                                     PART I

ITEM 1.  BUSINESS

GENERAL

    ADAC designs, develops, manufactures, sells and services medical imaging
equipment and radiation therapy planning and health care information software
systems used in hospitals and clinics worldwide. The Company conducts its
business primarily through its Medical Systems, Radiation Therapy Products
("RTP") and Health Care Information Systems ("HCIS") business units.

    On October 1, 1999, the Company purchased two related companies, UGM Medical
Systems, Inc. and UGM Laboratory, Inc. (together referred to as "UGM'). UGM is a
leading developer and manufacturer of positron emission tomography ("PET")
equipment and had been a long-term strategic partner of the Company. ADAC and
UGM co-developed MCD-PET-TM-, the first coincidence detection technology, which
enables ADAC's nuclear medicine systems to perform PET imaging. In addition,
ADAC had been the principal distributor of UGM's C-PET-TM-, a clinically
optimized dedicated PET scanner. The Company believes the acquisition will allow
ADAC to better position itself in the rapidly growing PET imaging market and
accelerate its product leadership in all areas of PET imaging.

    In October 1996, the United States Department of Commerce awarded ADAC a
Malcolm Baldrige National Quality Award in the large manufacturing category in
recognition of its performance management system and its achievements in quality
and business performance. ADAC is the first health care manufacturer ever to
receive this award.

    ADAC was incorporated in California on October 14, 1970. Its principal
offices are located at 540 Alder Drive, Milpitas, California, 95035. Its
telephone number at that location is (408) 321-9100.

MEDICAL SYSTEMS

    The Medical Systems business unit includes the Company's nuclear medicine
product and service businesses. Revenues also include sales from the Company's
ADAC Medical Technologies ("AMT") products. In the third quarter of fiscal 1999,
the Company decided to close its AMT refurbishing facility in Washington,
Missouri, and to relocate part of the business to Milpitas, California, where it
has been combined with the Medical Systems business unit. Medical Systems
revenues represented 75%, 74% and 83% of the Company's total revenues in fiscal
1999, 1998 and 1997, respectively. See Note 12 "Segment Reporting and Foreign
Operations" of Notes to Consolidated Financial Statements.

    NUCLEAR MEDICINE.  Nuclear medicine is a diagnostic imaging modality that
images the function or physiology of organs and lesions. In a typical nuclear
medicine procedure, the patient is administered a small amount of a
radiopharmaceutical that localizes in normal and abnormal tissues according to
the make-up of the radiopharmaceutical, the functionality of the tissue, and the
procedure being utilized. The patient is then imaged with a gamma camera and the
images are recorded on a computer. These images may be processed further as
described below. The physician uses the final images and related clinical
information to evaluate the functional and metabolic performance of the portion
of the patient's body under examination. Nuclear medicine is used primarily for
oncology and cardiology procedures, which account for approximately 70% of all
nuclear medicine procedures performed. The Company believes the

                                       2
<PAGE>
functional imaging capability of nuclear medicine may allow for earlier
diagnosis of certain diseases than anatomical imaging modalities such as
magnetic resonance imaging ("MRI"), computerized tomography ("CT"), and
ultrasound.

    In its Medical Systems business, the Company designs, develops,
manufactures, sells and services a broad line of nuclear medicine cameras and
related computer systems capable of performing single photon imaging and
positron emission tomography ("PET") imaging. These systems consist primarily of
a camera, a computer workstation and clinical software that permits the
physician to process the resulting data.

    SINGLE PHOTON IMAGING.  There are three general methods for acquiring single
photon nuclear medicine images: single photon emission computed tomography
("SPECT"), planar imaging and total or whole body imaging. In SPECT imaging, the
camera rotates around the patient to create three-dimensional images. Planar or
static images are acquired at a single angle relative to a patient and are
similar to a "snapshot" image. In total body imaging, the camera moves along the
length of the patient to form a single image of the whole body.

    The Company offers two different types of gamma cameras for performing
single photon imaging: single head cameras with one detector head and dual head
cameras with two detector heads. Dual head cameras offer better patient
throughput and higher image quality than single head cameras. Dual head cameras
may include fixed angle or variable angle detectors. The detectors on a fixed
angle camera are generally fixed at a 90 degrees orientation for cardiac imaging
or at a 180 degrees orientation for oncology or general purpose imaging. The
detectors on a variable angle camera may be positioned in both of these two
orientations as well as other positions which allow for more versatile clinical
applications.

    All of the Company's gamma cameras are equipped with the Company's EPIC-TM-
digital detector. This innovative technology improves the reliability and
stability of the nuclear image over that achieved through the use of analog
technology. The EPIC detector also includes auto-tuning and remote diagnostics
capabilities which facilitate improved field service efficiency and customer
satisfaction.

    The Company's dual head camera product line currently includes the
following:

    - SKYLIGHT-TM---the Company's recently introduced, revolutionary,
      gantry-free nuclear medicine gamma camera. This system provides greater
      openness and flexibility of applications. The SKYLight system is based on
      an architecture that allows gamma detectors to be mounted directly into a
      room structure, thus reducing limitations associated with gantry-based
      cameras. SKYLight is currently a work in progress, and, accordingly, will
      not contribute to the Company's revenues in fiscal 2000.

    - FORTE-TM---the Company's newest open gantry, variable angle camera. This
      camera features the Company's unique FreeDOME-TM- open gantry, which
      enables a fuller range of image acquisition without obstruction from
      detector arms or gantry feet and improved patient comfort for all imaging
      positions, including patients on hospital beds, gurneys and wheelchairs.
      This camera is sold with the latest Pegasys computer workstation, the Sun
      Ultra-TM-60, which offers a two-fold increase in processing speed and
      power over previous generations.

    - VERTEX-TM-V60--the Company's latest generation Vertex dual ring, variable
      angle camera. This camera is also sold with the Pegasys Sun Ultra 60
      computer workstation. The Company's advanced imaging technologies,
      including Molecular Coincidence Detection ("MCD-PET-TM-"), MCD with
      attenuation correction ("MCD/AC-PET-TM-") and Vantage-TM- ExSPECT-TM- are
      currently available on this camera.

    - CARDIO-TM- EPIC--the Company's dual ring, fixed 90 degree camera. This
      camera is based on the Vertex design and was engineered especially for the
      cardiology market. Due to the fixed angle of the detectors, this camera is
      less expensive than the Vertex V60 but also offers EPIC image quality and
      dual head throughput advantages for cardiology imaging.

                                       3
<PAGE>
    - SOLUS-TM- EPIC--the Company's dual ring, fixed 180 degree camera. This
      camera is based on the Vertex design and was engineered especially for the
      oncology market. Like the Cardio, this camera is less expensive than the
      Vertex V60 but offers EPIC image quality and dual head throughput
      advantages for oncology imaging. MCD-PET and MCD/AC-PET are both available
      on the Solus, thus enhancing the oncology applications of the camera.

    The Company's single head product line currently includes the following
cameras:

    - SINGLE HEAD GENESYS-TM---the Company's first single detector gamma camera
      that was designed for general purpose nuclear medicine studies. The
      robotics and patient ergonomics provide efficient patient handling and
      transition from total body to SPECT studies in oncology applications. The
      compact design allows installation into small rooms.

    - ARGUS-TM---the Company's second single detector gamma camera that was
      designed to perform general purpose nuclear medicine studies and give
      added flexibility for imaging patients when they are seated or in their
      hospital bed. The detector orientation affords a larger imaging field for
      SPECT procedures, especially for oncology imaging.

    The Company also manufactures and sells the Transcam-TM- and Thyrus-TM-
gamma cameras, which are niche cameras with a small field of view and are
produced by the Company's Danish subsidiary, ADAC Laboratories A/S. These
cameras offer planar imaging for specific clinical diagnostic procedures. In
addition the Transcam is mobile and allows imaging to be performed in the
hospital ward without moving the patient.

    The Company's gamma cameras are sold with a computer workstation that
enables the user to acquire the data collected by the detectors, to generate a
digital image from that data and to process the data and the resulting image
using a number of clinical software applications. Most of the Company's gamma
cameras are sold with the Sun Ultra or Ultra 60 workstation from Sun
Microsystems.

    POSITRON EMISSION TOMOGRAPHY IMAGING ("PET").  PET imaging is a valuable
diagnostic tool because of its high resolution and high accuracy in oncology,
cardiology and neurology. The Company's positron emission tomography products
consist of MCD-PET, and C-PET MCD-PET is a hardware and software upgrade to the
Vertex V60 and Solux Epic cameras that enables these SPECT cameras to perform
PET imaging. MCD-PET offers physicians the ability to perform PET imaging with a
gamma camera at a fraction of the cost of a dedicated PET system. C-PET is a
clinically optimized, dedicated PET scanner. C-PET was designed and developed by
UGM, which the Company acquired on October 1, 1999. See Note 4 "Acquisitions" of
Notes to Consolidated Financial Statements. ADAC had served as the exclusive
distributor of C-PET prior to the acquisition. The Company believes the
acquisition will allow ADAC to better position itself in the rapidly growing PET
imaging market and accelerate its product leadership in all areas of PET
imaging. C-PET gives ADAC a full line of PET systems to meet different customer
needs. The C-PET system enables more patients to be imaged in a day than the
camera-based PET systems and is focused on customers with a higher PET patient
load.

    ENHANCEMENTS AND OPTIONS.  In addition to MCD-PET, the Company offers a
number of other clinical hardware and software enhancements to its gamma cameras
that enable physicians to extract clinical information from nuclear medicine
procedures to aid in the diagnosis of disease including the following:

    - Vantage ExSPECT--Co-developed with Emory University, this product is
      offered as an upgrade to the Company's Vantage-TM- product, and corrects
      for image distortions created by variations in tissue density, scatter and
      resolution. Vantage ExSPECT is particularly useful in cardiac studies, and
      the Company believes it offers important advantages over cardiac
      ultrasound, the alternate competitive procedure. Vantage ExSPECT permits
      evaluations of perfusion.

                                       4
<PAGE>
    - MCD/AC-PET--This product is designed to correct for attenuation when
      imaging with MCD-PET and provides substantial improvements in image
      quality. Similar to Vantage, MCD/AC-PET corrects for image distortions
      created by variations in tissue density. It is important to note that
      attenuation is a greater problem in positron imaging because the photons
      travel twice as far through the body than in traditional nuclear medicine
      procedures. To date, the Company is the only vendor to offer attenuation
      correction for coincidence imaging with a gamma camera.

    - Quantitative Gated SPECT ("QGS-TM-")--Developed with Cedars Sinai Medical
      Center, this software provides essential information for the detection and
      analysis of cardiac disease and enables physicians to study a number of
      different snapshots of the heart simultaneously.

    - AutoSPECT Plus-TM---This product allows physicians to automatically
      process through the use of a single button one or more cardiac SPECT,
      gated SPECT, Vantage SPECT and MCD/AC-PET data sets. Automated processing
      offers the following advantages over manual processing: reproducible and
      accurate results, reduced artifacts and processing time and increased
      efficiency.

    - AutoQUANT-TM---Jointly developed and under an exclusive license with
      Cedars Sinai Medical Center, this product provides comprehensive cardiac
      quantitative analysis capability with state of the art algorithms and an
      intuitive user interface. This product combines perfusion and functional
      information that is essential for the detection and analysis of cardiac
      disease and enables physicians to study a number of different quantitative
      parameters of the heart simultaneously.

    - Shadow-TM---This product enables remote processing of cardiac studies. The
      physician can process and review patient studies using a desktop PC
      networked to a Pegasys computer system. Shadow improves workflow by
      allowing the physician to obtain direct access from their office or
      viewing area to patient data acquired using a gamma camera.

    - Image Fusion and Review--This product is used to align and display
      different images such as MCD-PET, SPECT, PET, CT and MRI in three
      dimensions as composite images. Image Fusion also permits the operator to
      manipulate and align the images. This functionality facilitates image
      interpretation by a physician by combining functional and anatomical data
      in the same image.

    ADAC MEDICAL TECHNOLOGIES.  In the third quarter of fiscal 1999, the Company
decided to close its AMT refurbishing facility in Washington, Missouri, and
relocate the business to Milpitas, California. A restructuring charge of
$0.5 million was taken as a result of this action. See Note 3 "Restructuring
Charges" of Notes to Consolidated Financial Statements. Also in the third
quarter of fiscal 1999, the Company decided to discontinue refurbishment of a
number of lines of older and non-ADAC nuclear medicine equipment, the demand for
which was declining. These decisions, as well as existing market conditions,
rendered obsolete substantial inventories of equipment and parts, resulting in a
non-ordinary charge of $2.4 million in the third quarter of fiscal 1999. See
Note 10 "Non-Ordinary Charges and Expenses" of Notes to Consolidated Financial
Statements.

    CUSTOMER SUPPORT AND FIELD SERVICE.  The Company maintains a customer
support center in California, and field service forces in North America and
Europe for its Medical Systems business. The Company's network of service
engineers and customer support specialists provide installation, warranty,
repair, training and support services. Together with its distributors, the
Company services over 10,800 installed systems at over 3,650 sites worldwide,
including approximately 600 systems manufactured by vendors other than ADAC. The
Company generates service revenue under service contracts and by providing
service on a time and materials basis.

RADIATION THERAPY PRODUCTS ("RTP")

    The RTP business unit includes the Company's Radiation Therapy Planning and
its Radiology Solutions ("ARS") divisions. Revenues from the RTP business unit
represented 14%, 13% and 6% of the

                                       5
<PAGE>
Company's total revenues in fiscal 1999, 1998 and 1997, respectively. See
Note 12 "Segment Reporting and Foreign Operations" of Notes to Consolidated
Financial Statements.

    RADIATION THERAPY PRODUCTS.  In RTP, the Company designs, develops, markets
and supports turnkey radiation therapy planning systems that assist hospital
radiation oncology departments and cancer treatment centers in planning patient
treatments. The systems combine third-party workstations and printers with the
Company's proprietary application software, Pinnacle-TM-(3).

    RTP's principal product, Pinnacle(3), is a radiation therapy treatment
planning system that includes two-dimensional and three-dimensional planning
capabilities for radiation treatments. This includes implanting radioactive
sources (brachytherapy) and delivery of photon or electron particles at several
angles (stereotactic radiosurgery) for treatments of patients with cancer, as
well as certain benign conditions. Pinnacle(3)'s three-dimensional volumetric
image processing and dose computation capabilities enable physicians to plan the
precise application of high energy radiation to a specific targeted area for the
treatment of cancer and other diseases. The Company believes Pinnacle(3)
provides improved image processing and dose calculation methods compared to
other currently available products.

    ADAC RADIOLOGY SOLUTIONS.  In its ARS business, the Company refurbishes,
sells and services previously owned CT systems. The Company entered this
business in fiscal 1998 through the acquisition of Southern CATS, Inc. in
October 1997 and CT Solutions, Inc. in January 1998. See Note 4 "Acquisitions"
of Notes to Consolidated Financial Statements. The ARS business benefits from
synergies with ADAC's existing RTP division in the area of CT simulation. CT
simulation is a growing trend in radiation therapy planning. By bundling a
refurbished CT with the CT simulation component of the Pinnacle(3) treatment
planning system, ADAC is able to offer a very cost-effective solution enabling
oncology centers to adopt this new technology sooner.

HEALTH CARE INFORMATION SYSTEMS ("HCIS")

    The Company's HCIS division designs, develops, markets, sells and supports
integrated solutions consisting of computer equipment and software applications
that offer health care providers the necessary tools to process and archive
patient and clinical information. HCIS revenues represented 11%, 13% and 11% of
the Company's total revenues in fiscal 1999, 1998 and 1997, respectively. See
Note 12 "Segment Reporting and Foreign Operations" of Notes to Consolidated
Financial Statements.

    The Company's principal HCIS products are ENVOI-TM-, an integrated Image and
Information Management Solution, and CorCAAT-TM-, a cardiology information
system product. ENVOI includes QuadRIS-TM-, Physician Desktop-TM-, Intranet
Image Server, DICOM, Diagnostic and Clinical review workstations, and the
recently introduced integrated Workflow Manager. ENVOI's open clinical
architecture combines Oracle's-TM- relational database technology with Microsoft
Windows-TM- client/server software to deliver radiology information not just
within the radiology department, but throughout the health care delivery
network. In this environment, the product solution must meet the demands of
multiple health care facilities that act as a single integrated delivery
network. Physician Desktop, with integrated voice recognition and digital
dictation, enables radiologists to review patient examination history and
previous reports, as well as verify and sign-off on reports. ENVOI's Intranet
Image Server delivers an integrated image and information management solution
that provides real-time access to images and reports for radiologists, referring
physicians, and emergency room, intensive care and cardiac care unit
technologists. Utilizing an Internet browser and industry communications
standard such as DICOM, as well as other Internet protocols, ENVOI provides
immediate, secure access to images and reports for radiologists, referring
physicians and technologists.

    In October 1999, the Company signed a strategic alliance agreement with
Cedara Software to develop and market Picture Archiving Communications Systems
("PACS"). The Company believes that the integration of Cedara's image management
technology into the ENVOI product line will allow it to provide a clearly
differentiated full scale PACS offering to the market.

                                       6
<PAGE>
    In November 1999, the Company signed an agreement with Perot Systems. Under
this multi-year agreement Perot Systems Healthcare Services Group will provide
implementation and related services for the QuadRIS and ENVOI-TM- product lines.
Perot Systems will supply the full scope of services required for successful
large scale implementations, including system integration, network design and
implementation, clinical process reengineering and implementation of the
Company's Web-based technology.

    The Company also markets CorCAAT, a cardiac catheterization laboratory
information system. CorCAAT performs a number of functions that previously
required equipment and systems from multiple vendors and eliminates the need for
expensive and inflexible interfaces. CorCAAT also simplifies the patient
monitoring, inventory management, case reporting, image management and outcomes
management processes by providing a single point of access to all
catheterization laboratory data. The product is based on networked computing
technology and standard components including Microsoft Windows NT-TM-, Microsoft
SQL Server-TM- and Intel-TM--based computers. CorCAAT is currently installed at
25 sites in the United States.

    In the first quarter of fiscal 1998, the Company discontinued developing and
marketing LabStat-TM-, the Company's laboratory information system, while
retaining its laboratory support and maintenance business. As a result, the
Company took an non-ordinary charge of $11.3 million in that quarter. See
Note 10 "Non-Ordinary Charges and Expenses" of Notes to Consolidated Financial
Statements.

    The Company also supports a line of other more mature products, including
LabCare-TM-, MARS II-TM-, and IMAGES/3000-TM-, which are installed in hospitals
throughout the United States and Canada.

OTHER

    From time to time, the Company explores other opportunities for expanding
its business. On October 30, 1997, ADAC Radiology Services exercised an option
to acquire the business of Medical Transition Strategies, Inc., which was in the
business of forming and managing radiology networks. Because, among other
things, this business did not contribute meaningfully to the Company's results
in fiscal 1998, and was not expected to do so in future periods, the Company
decided to discontinue this business in the fourth quarter of fiscal 1998. As a
result, the Company took a non-ordinary charge of $1.9 million in that quarter.
See Note 10 "Non-Ordinary Charges and Expenses" of Notes to Consolidated
Financial Statements.

MARKETING AND SALES

    ADAC has a direct sales force in the United States. The Company also
conducts certain direct sales and/or service activities through its subsidiaries
in the Netherlands, Germany, France, Italy, Denmark, the United Kingdom, Canada
and Brazil. Sales and service in other countries are generally handled by
distributors. The Company is currently in the process of restructuring its
operations in Brazil and intends to handle all future sales through a
distributor. North America is the largest market for the Company's products and
services followed by Europe, Japan, Asia Pacific and South America. ADAC is
represented in all of these geographic areas. See Note 12 "Segment Reporting and
Foreign Operations" of Notes to Consolidated Financial Statements.

RESEARCH AND DEVELOPMENT

    Developing products, systems and services based on advanced technological
concepts is essential to ADAC's ability to compete effectively. The Company
currently maintains a product development and engineering staff responsible for
product design and engineering. In addition, as part of ADAC's research and
development programs, the Company has established the Advanced Clinical Research
Program, which provides annual grants to clinical trial sites at major
institutions to assist the Company in product development concepts and to aid in
verifying engineering and design activities. There can be no assurance that the
Company's product development efforts will result in the development or
commercialization of

                                       7
<PAGE>
successful products or product enhancements. Research and development
expenditures, net of software capitalization, totaled $18.2, $16.8 and
$16.7 million in fiscal 1999, 1998, and 1997, respectively.

COMPETITION

    The markets in which the Company competes are characterized by rapidly
evolving technology, intense competition and pricing pressure. There are a
number of companies that currently offer or are in the process of developing
products that compete with products offered by the Company. Some of these
competitors have substantially greater capital, manufacturing and other
resources than the Company. These competitors could develop technologies and
products that are more effective than those currently used or produced by the
Company or that could render the Company's products obsolete or noncompetitive.
In addition, as the Company enters new markets, there can be no assurance that
the Company will be able to penetrate such markets successfully.

    In the nuclear medicine market, the Company competes with several other
major suppliers. From the end of fiscal 1998 to the end of fiscal 1999, the U.S.
nuclear medicine market grew approximately 4%. According to data provided by the
National Electronics Manufacturers Association ("NEMA"), ADAC's share of the
U.S. market, based on bookings volume, was approximately 41% for fiscal 1999,
which represents approximately a 3% percentage point decrease in market share
from the prior year. During this period, according to the same NEMA data, the
Company maintained its price premium of approximately 5% in the dual head market
over its competitors. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Business Considerations."

    The Company believes that the key to success in its markets is to provide
technologically superior products that deliver cost-effective, high quality
clinically diagnostic data and images that meet or exceed customer quality and
service expectations. ADAC's ability to compete successfully depends on its
ability to commercialize new products ahead of its competitors. In addition to
the rapid development of innovative and cost-effective new products, the Company
believes that other competitive factors include patient throughput, system
functionality and reliability, image quality, computer processing speed,
customer service and support, and worldwide distribution network. The Company's
products also must focus on solutions for the managed care environment in order
to improve clinical outcomes at lower clinical process costs.

    The Company believes that other key competitive factors in RTP and HCIS
include system architecture, key proprietary algorithms, functionality of the
application software, post-sales support services, time to market, integration
expertise with hospital information systems and price/performance.

MANUFACTURING AND SUPPLIERS

    The Company's manufacturing process includes mechanical assembly, final
system integration and testing. In 1996, the Company's nuclear medicine
manufacturing operations in Milpitas, California were certified to the
requirements of the international quality system requirements of ISO 9001.

    The Company purchases certain sub-systems, including Sun-TM- workstations,
disk drives and sodium iodide crystals, from third party suppliers. Although
most materials and purchased components for its products are available from more
than one source of supply, certain essential components such as the sodium
iodide crystals included in its gamma cameras are presently available from only
one supplier. The Company also relies on several significant vendors for
hardware and software components for its HCIS products such as Hewlett-Packard
Company, Oracle Corporation and others. The loss of any of these suppliers,
including any single-source supplier, would require obtaining one or more
replacement suppliers as well as potentially requiring a significant level of
hardware and software development to incorporate the new parts into the
Company's products. Although the Company has obtained insurance to protect
against loss due to business interruption from these and other sources, there
can be no assurance that such coverage would be adequate.

GOVERNMENT REGULATION

    ADAC's Medical Systems and RTP businesses, as well as certain portions of
its HCIS business, are regulated by the United States Food and Drug
Administration ("FDA"). The FDA regulates the development, testing,
manufacturing, packaging, labeling, distribution and marketing of medical
devices under the Federal, Food, Drug and Cosmetic Act (the "FDC Act") and
regulations promulgated by the FDA. The State of California (through its
Department of Health Services), where the Company maintains its factory, as well
as other states, also regulates the manufacture of medical devices.

    In general, these laws require that manufacturers adhere to certain
standards designed to ensure the safety and effectiveness of medical devices.
Under the FDC Act, each medical device manufacturer must comply with
requirements applicable to manufacturing practices, clinical investigations
involving humans, sale and marketing of medical devices, post-market
surveillance, repairs, replacements and refunds, recalls and other matters. The
FDA is authorized to obtain and inspect devices and their labeling and
advertising, and to inspect the facilities in which they are manufactured.

    The FDC Act also requires compliance with specific manufacturing and quality
assurance standards, including regulations promulgated by the FDA with respect
to good manufacturing practices ("GMP"). FDA regulations, specifically the
Quality System Regulation ("QSR"), require that each manufacturer establish a
quality assurance program by which the manufacturer monitors the manufacturing
process and maintains records that show compliance with FDA regulations and the
manufacturer's written specifications and procedures relating to the devices.
Compliance is necessary to receive FDA clearance to market new products and is
necessary for a manufacturer to be able to continue to market cleared product
offerings. Recently, the FDA promulgated new design process regulations that
revised and expanded the good manufacturing practices applicable to medical
device manufacturers. Among other things, these new regulations require that
manufacturers establish a formalized design control process. The QSR took effect
on June 1, 1997, and included a twelve-month transition period during which
enforcement action with respect to design control requirements was not to be
taken. That transition period has expired and the regulation is in full force
and effect.

    The FDA makes unannounced inspections of medical device manufacturers and
may issue reports of observations where the manufacturer has failed to comply
with applicable regulations and/or procedures. Failure to comply with applicable
regulatory requirements can, among other things, result in warning letters,
civil penalties, injunctions, suspensions or losses of regulatory clearances,
product recalls, seizure or administrative detention of products, operating
restrictions through consent decrees or otherwise, and criminal prosecution,
which could have a material adverse effect upon the Company.

    The FDA requires that a new medical device or a new indication for use of or
other significant change in an existing medical device obtain either 510(k)
premarket notification clearance or an approved Pre-Market Approval Application
("PMAA") before orders can be obtained and the product distributed in the United
States. The 510(k) clearance process is applicable when the new product being
submitted is substantially equivalent to an existing commercially available
product. If a product does not meet the eligibility requirements for the 510(k)
process, then it must instead be submitted under the PMAA process. The process
of obtaining 510(k) clearance may take at least three months from the date of
filing of the application and generally requires the submission of supporting
data, which can be extensive and extend the process for a considerable period of
time. Under the PMAA process, the applicant must generally conduct at least one
clinical investigation and submit extensive supporting data and clinical
information in the PMAA, which typically takes from one to two years, but
sometimes longer for the FDA to review. Generally, the Company has not been
required to resort to the PMAA process for approval of its products.

    The sale of medical devices outside the United States is subject to foreign
regulatory requirements that vary widely from country to country. The time
required to obtain clearance in foreign countries may be longer or shorter than
in the United States. In 1995, ADAC implemented a program to enter the Japanese
market and has, through its distributor, received Japanese Ministry of Health
and Welfare

                                       9
<PAGE>
(JMHW) approval to market the Forte, Vertex V60, Cardio Epic, Solus Epic, and
MCD-PET with the Company's Pegasys Ultra-TM- computer system. In addition, ADAC
has met the requirements of the European Medical Device Directive, which became
effective in the European Community in June 1998, for its principal products.
Failure of the Company to comply with these requirements could have a material
adverse effect on the Company's results of operations and financial condition.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Business Considerations".

    In mid-1997, the FDA conducted an inspection of the Company's newly acquired
subsidiary, Cortet, Inc. ("Cortet"). As a result of that inspection, Cortet
received a Warning Letter from the FDA containing inspectional observations
relating to the adequacies of Cortet's quality assurance system. Cortet
responded to the FDA's observations and Warning Letter and, in October 1997,
received correspondence from the FDA indicating that Cortet's responses appeared
to adequately address the FDA's concerns. In mid-1998, the State of California,
under a contract with the FDA, completed a routine inspection of ADAC's facility
in Milpitas, California. The state investigator issued a FDA Form 483 containing
observations of non-compliance of the recently implemented QSR. The state
investigator also placed a temporary shipment hold on Pinnacle(3) pending the
Company satisfactorily responding to the State's concerns regarding the
Company's quality systems. The Company promptly responded to the FDA and the
State and initiated a number of corrective actions. The State lifted the
Pinnacle(3)shipment hold on August 28, 1998 and, in September 1998, ADAC
received a letter from the FDA indicating that the Company had adequately
responded to the FDA's concerns. Although the Company was deemed to have
adequately responded to the State and FDA following the mid-1998 inspection, the
Company is responsible for the full implementation of all corrective actions. In
addition, as all companies are, the Company remains subject to periodic
inspections in the future and there can be no assurance as to the timing or
outcome of any subsequent inspection. The scope of any re-inspection could be
more comprehensive than the inspections of Cortet and the Company's Milpitas
facility, and there can be no assurance that the FDA, upon re-inspection, will
deem the Company's corrective actions to be adequate or that additional
corrective action, in areas not addressed in the Warning Letter or the
Form 483, will not be required. Any failure by the Company to fully implement
the required corrective actions or to comply with any other applicable
regulatory requirements could have a material adverse effect on the Company's
ability to continue to manufacture and distribute its products, and in more
serious cases, could result in seizure, recall, injunction and/or civil fines.
Any of the foregoing, would have a material adverse effect on the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Business Considerations".

    Certain additional requirements of other Federal laws and of state, local
and foreign governments exist which may apply to the manufacture and marketing
of the Company's products and to products such as radiopharmaceuticals or
possession and use of radioactive materials that are used in conjunction with
the Company's products.

    The Company is subject to various environmental laws and regulations both in
the United States and abroad. The operations of the Company, like those of other
medical device companies, involve the use of substances regulated under
environmental laws.

PATENT, COPYRIGHTS AND ROYALTIES

    The Company relies on a combination of trade secret, copyright, patent and
trademark laws and contractual provisions to protect its proprietary rights. The
Company has a policy of undertaking an ongoing review of its products with
patent counsel to determine to what extent its products may be prosecutable
under the patent or copyright laws and taking appropriate action to protect its
intellectual property based on such review. While the Company believes that it
benefits from such patents, competitors may develop competing products by
"designing around" patents held by the Company or may claim that the Company's
products infringe their proprietary rights.

                                       10
<PAGE>
    The Company develops application software for its products and also licenses
software components from third parties. Third party software developers include
software companies and clinical development sites that provide turnkey products
or software code. Under its agreements with third parties, the Company generally
obtains a license to use the third party software and to include such software
in its own products for a specified period of time in exchange for the payment
of a royalty to the developer. These agreements may be either exclusive or
non-exclusive.

EMPLOYEES

    As of November 30, 1999, the Company had approximately 1,070 full-time
employees worldwide, including 800 employed in Medical Systems, 100 in RTP and
170 in HCIS business units. None of the Company's employees are represented by a
labor union. The Company believes its relations with its employees are good.
Many of the Company's employees are highly skilled and competition in recruiting
and retaining such employees is intense. The Company believes its continued
success is dependent in part upon its ability to continue to attract and retain
highly qualified personnel.

ITEM 2. PROPERTIES

    The Company's principal administrative, manufacturing and research
operations occupy approximately 200,000 square feet of leased space in buildings
located in Milpitas, California, under leases expiring through 2006. The
Company's principal health care information systems operations occupy
approximately 54,000 square feet of leased space in buildings located in
Houston, Texas, under leases expiring in 2002. Other smaller facilities are
leased in various states and foreign countries. Management believes that the
Company's facilities are adequate at least through fiscal 2000 to meet presently
anticipated manufacturing and other requirements. See Note 6 "Commitments and
Contingencies" of Notes to Consolidated Financial Statements.

ITEM 3. LEGAL PROCEEDINGS

    Commencing in December 1998, a total of eleven class action lawsuits were
filed in federal court by or on behalf of stockholders who purchased Company
stock between January 10, 1996 and December 28, 1998. These actions name as
defendants the Company and certain of its present and former officers and
directors. The complaints allege various violations of the federal securities
laws in connection with the restatement of the Company's financial statements
and seek unspecified but potentially significant damages. In April 1999, these
actions were ordered consolidated and, in July 1999, the plaintiffs filed a
consolidated amended complaint. The Company intends to contest this action
vigorously. A stockholder derivative action, purportedly on behalf of the
Company and naming as defendants Company officers and directors was also filed
in state court seeking recovery for the Company based on stock sales by these
defendants during the above time period. The Company is also a defendant in
various legal proceedings incidental to its business.

    While it is not possible to determine the ultimate outcome of these actions
at this time, management is of the opinion that any liability resulting from
these claims would not have a material adverse effect on the Company's
consolidated financial position. However, the outcome of these actions could
have a material adverse effect on the Company's results of operations or cash
flows.

    The Company has been informed that the United States Securities and Exchange
Commission (SEC) has issued a Formal Order of Private Investigation in
connection with matters relating to the Company's previously announced
restatement of its financial results for 1996, 1997 and the first three quarters
of 1998. The Company is continuing to cooperate with the SEC. The Company is
unable to predict the outcome of the investigation at this time.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

    The following discussion and analysis should be read in conjunction with the
Company's Consolidated Financial Statements and related Notes thereto contained
elsewhere within this document.

OVERVIEW

    The Company's fiscal year ends on the Sunday closest to September 30. Fiscal
1999 included 53 weeks, while fiscal 1998 and 1997 included 52 weeks.

    Prior to fiscal 1999, the results of the Company's RTP and HCIS divisions
were combined under Software Business for the purposes of Management's
Discussion and Analysis. However, due to continued growth, the results of each
division are now presented separately. The results of the Company's ARS business
unit were presented under Medical Systems prior to fiscal 1999 for the purposes
of Management's Discussion and Analysis. The ARS business unit is now presented
under RTP, this coincides with the Company's decision to move the management of
ARS under RTP. The ARS business benefits from synergies with the RTP division in
the area of CT simulation. All historical data and comparisons have been
restated to reflect these changes.

UGM ACQUISITION

    On October 1, 1999, the Company acquired two related companies, UGM Medical
Systems Inc. and UGM Laboratories, Inc. (together "UGM") for $18.5 million. UGM
was an independent developer and manufacturer of PET equipment, for which the
Company has been its principal distributor. The acquisition was accounted for
using the purchase method of accounting and the results of UGM have been
included in the Company's financial statements subsequent to October 1, 1999.
The amortization of goodwill, acquired technology and workforce is being
computed on the straight-line basis over lives of 6 to 15 years.

    The Company recognized a pre-tax charge to operations of $1.4 million for
the purchase of acquired in-process research and development. This charge was
computed using the percent complete method, discounting the relevant future cash
flows at 40% to reflect the weighted average cost of capital and the specific
risks associated with each in-process product.

                                       13
<PAGE>
    Further, the Company may be required to pay additional purchase price
consideration and incur future compensation in amounts not exceeding $18.0 and
$2.0 million, respectively, pursuant to the terms of certain earn out
provisions. The performance period for such provisions is five years.

FISCAL 1999 COMPARED TO FISCAL 1998 AND FISCAL 1997

    Revenues for fiscal years 1999, 1998 and 1997 were $342.1, $300.5 and
$263.9 million, respectively. Revenues increased 14% from fiscal 1998 to 1999
and 14% from fiscal 1997 to 1998. Medical Systems revenues represented 75%, 74%
and 83% of the Company's total revenues in fiscal 1999, 1998 and 1997,
respectively. RTP revenues represented approximately 14%, 13% and 6% of the
Company's total revenues in fiscal 1999, 1998 and 1997, respectively. HCIS
revenues represented approximately 11%, 13% and 11% of the Company's total
revenues in fiscal 1999, 1998 and 1997, respectively. Gross profit for fiscal
1999 totaled $102.4 million, a decrease of 5% from gross profit of
$107.8 million in fiscal 1998, which increased 4% over gross profit of
$103.8 million in fiscal 1997.

NON-ORDINARY CHARGES AND EXPENSES

INVENTORY AND RECEIVABLES

    During fiscal 1998, the Company began an examination of the performance,
profitability and prospects of its various business units as part of an overall
evaluation of its business and internal controls. In connection with this
examination, the Company identified issues relating to its application of
accounting principles and conducted a review of its asset carrying values,
accruals and expenses in historical financial periods, leading to a restatement
of reported financial results for fiscal 1996, fiscal 1997 and the first three
quarters of fiscal 1998. Following the restatement, the Company continued to
focus on its accounting systems and weaknesses in its internal controls and the
assessment of its business units. As part of this focus and assessment, and
against the background of increasing competition in certain of the Company's
markets, new product introductions by the Company and its competitors, and its
customers deferring purchasing decisions due to their perceived Year 2000
compliance risks, the Company revised its estimates of 1) the recoverability of
the Company's inventory to reflect its lower build plans which resulted in
increased levels of potentially excess and obsolete inventory, 2) the
collectibility of receivables, and 3) the value of certain other assets carried
on the Company's books.

    The Company also decided to close its AMT refurbishing facility in
Washington, Missouri, relocate the business to Milpitas, California, and
discontinue refurbishment of a number of lines of older nuclear medicine
equipment, the demand for which was declining. These fiscal 1999 decisions, as
well as existing market conditions, rendered obsolete substantial inventories of
equipment and parts.

    The Company's financial statements for fiscal 1999 include charges for these
changes in estimates of $13.6 million related to inventory and $6.0 million
related to receivables (excluding South American receivables).

SOUTH AMERICA

    As previously disclosed in the Company's Form 10-Q for the quarter ended
April 4, 1999, a significant number of the Company's customers in its principal
South American markets of Brazil, Argentina and Colombia are delinquent in
making periodic payments due under the terms of sales previously made to them,
many of which were supported by third-party financing arrangements that involve
full or partial recourse to the Company. Deteriorating economic conditions and
currency devaluations occurring primarily during fiscal 1999, and ineffective
monitoring of delinquencies and collection efforts by the Company, may have all
contributed to delays in the collection of accounts receivable from customers in
these markets. During fiscal 1999, the Company undertook renewed collection
efforts and completed an evaluation of each receivable balance and recourse
obligation to determine the level of reserves required

                                       14
<PAGE>
for these customers. As a result of this evaluation, the Company has revised its
estimate of the recoverability of its South American receivables and recourse
obligations and provided additional reserves of $8.9 million during fiscal 1999,
of which, $1.8 million was recorded in the fourth quarter. These charges
resulted in total reserves of $9.8 million against total gross receivables and
recourse obligations for South America of approximately $12.8 million.
Consequently, at October 3, 1999, the Company has net South American receivables
of $1.8 million and recourse contingencies of $1.2 million.

LITIGATION

    In the fourth quarter of fiscal 1999, the Company incurred $1.2 million in
litigation expenses related to the pending class action lawsuit and stockholder
derivative action. See Note 6 "Commitments and Contingencies" of Notes to
Consolidated Financial Statements.

    The Company has concentrated resources on continuing to improve its
accounting systems and internal controls, and has retained a nationally
recognized accounting firm as a consultant and internal auditor. That firm has
developed a number of recommendations and has been retained to assist the
Company in implementing them. Among other things, the Company is attempting to
integrate more closely its inventory procurement procedures with the process of
developing and introducing new products in order to reduce the risk of
substantial inventories being obsoleted by product introductions. Furthermore,
with respect to receivables, the Company is improving its sales order and
collection procedures related to product and field service sales, and the sale
of ancillary products which resulted in the majority of the additional
receivables reserves added during fiscal 1999.

</TABLE>

    Medical Systems product revenues increased 10% from fiscal 1998 to fiscal
1999 and decreased 3% from fiscal 1997 to fiscal 1998. The increase in fiscal
1999 was driven by increased sales and installations due to readiness of
customers sites matched with the availability of cameras. The proportion of the
Company's revenues derived from North America increased because of the relative
deterioration of economic and business conditions in Europe and South America,
and because the Company was able to more quickly complete installations of
ordered products in North America than in those other regions. The product
revenue decline in fiscal 1998 was due to the timing of delivery for
installations caused by a longer product installation process.

    Gross margins for Medical Systems products decreased 15% and 3% in fiscal
1999 and 1998, respectively. The decline in gross margin for fiscal 1999 is
primarily attributable to the non-ordinary charges and expenses associated with
product inventory of $11.1 million. See Note 10 "Non-Ordinary Charges and
Expenses" of Notes to Consolidated Financial Statements. There was a further
charge of $3.3 million from a book to physical inventory adjustment identified
in fiscal 1999 in the Company's AMT equipment refurbishment business.

    Gross margins for fiscal 1999 were also adversely affected by a reduced
build plan, due to the Company's effort to decrease finished goods inventory.
With fewer units manufactured the cost per unit increased. Gross margins were
further adversely affected by competitive pricing pressures, the transition to
new products with higher costs on initial shipments and higher overhead expenses
associated with adding to the management team.

    The decline in gross margin for fiscal 1998 is attributable to a charge of
$4.9 million related to a carrying value adjustment for inventory and a
discontinued product charge for the Company's Digital Subtraction Angiography
("DSA") of $2.4 million. See Note 10 "Non-Ordinary Charges and Expenses" of
Notes to Consolidated Financial Statements.

    Medical Systems service revenues increased 29% from fiscal 1998 to fiscal
1999 and increased 15% from fiscal 1997 to fiscal 1998. The increases in fiscal
1999 and 1998 resulted from a continued higher number of customers under service
contract as the installed base of the Company's equipment grew. Additionally,
revenue for upgrades increased from services provided to bring customer's
equipment into Year 2000 compliance. Service margins decreased 3% from fiscal
1998 to fiscal 1999 and decreased 2% from fiscal 1997 to fiscal 1998. The
decline in fiscal 1999 was caused by the write-off of approximately
$0.8 million of excess inventory of consumable spare parts held in the field and
from increases in international parts expenses. Service margins decreased in
fiscal 1998 due to increased staffing and higher retrofit costs.

    Parts used for servicing installed equipment are stated at cost and
depreciation is computed over the estimated useful life. During fiscal 1999, the
Company reviewed the composition of its capitalized field service inventory and
the estimated collective useful life of this asset. As a result of this review,
effective beginning in the fourth quarter of fiscal 1999, the Company revised
its method of computing depreciation on its existing service parts inventory
from 10 years using the declining balance method to 5 years on the straight line
method. Depreciation on all service parts capitalized in the future will be
computed over 7 years on the straight line method. These revisions had an
immaterial effect on the results of operations. The Company will continue to
monitor recoverability of the collective asset under SFAS No. 121 "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of."

RADIATION THERAPY PRODUCTS ("RTP")

    RTP revenues are generated primarily from the sale and support of the
Company's Pinnacle(3) radiation therapy planning system. RTP revenues also
include sales from the Company's CT refurbishing business unit, ARS. Summary
information related to RTP product and support revenues and gross profit margins
for fiscal 1999 compared to fiscal 1998 and fiscal 1997 are as follows:

</TABLE>

    RTP product revenues increased 24% from fiscal 1998 to fiscal 1999 and
increased 118% from fiscal 1997 to fiscal 1998. The increase in fiscal 1999 and
1998 was driven by the market acceptance of the Pinnacle(3) product and the
formation of the ARS refurbishing business early in fiscal 1998.

                                       17
<PAGE>
    Gross margins for RTP products decreased 9% from fiscal 1998 to fiscal 1999
and increased 6% from fiscal 1997 to fiscal 1998. The decrease in fiscal 1999
resulted from several factors. First, there was a change in product mix, with
the lower margin ARS refurbishing business being a larger share of revenue. This
resulted in a decline in the overall RTP margin of 4%. Second, there was a
charge of $0.9 million for the reduced market value of ARS inventory, which
reduced the margin by 2%. See Note 10 "Non-Ordinary Charges and Expenses" of
Notes to Consolidated Financial Statements. Lastly, pricing pressures and other
margin charges account for the remainder of the overall decline in gross
margins. The increase in fiscal 1998 compared to fiscal 1997 was the result of
increased sales of the higher margin Pinnacle(3) product.

    RTP service revenues for fiscal 1999 and 1998 were from the ARS refurbishing
business that was formed in early fiscal 1998. In November 1998, ARS exited the
low margin x-ray service business, causing service revenues to decrease 19% and
service margins to increase 9% in fiscal 1999.

HEALTH CARE INFORMATION SYSTEMS ("HCIS")

    HCIS historically generated revenues from the sale of radiology, laboratory
and cardiology information systems as well as from providing support for these
products. In the first quarter of fiscal 1998, the Company took a non-ordinary
charge of $11.3 million to discontinue the development and marketing of LabStat,
its laboratory information system product, based on a decision by the Company's
Board of Directors made in that quarter. See Note 10 "Non-Ordinary Charges and
Expenses" of Notes to Consolidated Financial Statements. HCIS' current revenues
are derived from the sale and support of radiology and cardiology information
systems and the support of the Company's legacy laboratory information systems.
Summary information related to HCIS product and support revenues and gross
profit margins for fiscal 1999 compared to fiscal 1998 and fiscal 1997 are as

    HCIS product revenues increased 2% from fiscal 1998 to fiscal 1999 and
increased 73% from fiscal 1997 to fiscal 1998. The Company believes the reduced
revenue growth for fiscal 1999 was due to customers deferring purchasing
decisions due to their perceived Year 2000 risks. The revenue growth in fiscal
1998 was due to greater penetration of the commercial sector by HCIS' QuadRIS
product and continued growth in government sales under the Company's digital
imaging network--picture archiving communications systems (DIN-PACS) contract
with the United States Department of Defense.

                                       18
<PAGE>
    Gross margins on HCIS products from fiscal 1998 to fiscal 1999 increased due
to a $11.3 million charge associated with the discontinuance of the LabStat in
fiscal 1998. See Note 10 "Non-Ordinary Charges and Expenses" of Notes to
Consolidated Financial Statements. Excluding the effects of this discontinued
product charge, gross profit margins for HCIS products were comparable in fiscal
1998 and 1999, and increased in fiscal 1998 from fiscal 1997 due to DIN-PACS
contracts, fixed costs being absorbed by a greater number of unit sales, and the
discontinuance of the lower margin LabStat product.

    HCIS service revenues decreased 8% from fiscal 1998 to fiscal 1999 due to
fewer laboratory service contracts from the legacy product, LabStat. Service
revenues increased 6% from fiscal 1997 to fiscal 1998 due to increased radiology
hardware support revenues and growth in the QuadRIS installed base. Service
gross margins increased 4% from fiscal 1998 to fiscal 1999 due to the decline in
lower margin third party maintenance fees. Service gross margins increased 2%
from fiscal 1997 to fiscal 1998 due to the increased QuadRIS installed base.

</TABLE>

    Marketing and sales expenses totaled $62.4, $49.6 and $41.6 million in
fiscal 1999, 1998 and 1997, respectively. Marketing and sales expenses increased
$12.8 million in fiscal 1999 and $8.0 million in fiscal 1998, when compared to
respective prior fiscal years. The fiscal 1999 increase can be attributed to
commissions associated with higher revenues, increased international sales
expense from RTP, HCIS ENVOI product marketing spending and field service
commissions related to year 2000 compliance work. The fiscal 1998 increase is
primarily attributed to higher revenues.

    Research and development expenses, net of software capitalization, totaled
$18.2, $16.8 and $16.7 million in fiscal 1999, 1998, and 1997, respectively.
Research and development expenses, net of software capitalization expenses,
increased $1.4 million in fiscal 1999 and $0.1 million in fiscal 1998, when
compared to respective prior fiscal years. The increase in fiscal 1999 is due to
new development programs in Medical Systems and RTP. The increase in fiscal 1998
is a result of additional investments made by the Company to accelerate the
development of the Company's laboratory product and to maintain and enhance the
Company's radiology product. Capitalized software costs were $8.9, $7.0 and
$4.5 million in fiscal 1999, 1998 and 1997, respectively.

    General and administrative expenses totaled $53.6, $19.5 and $15.9 million
in fiscal 1999, 1998 and 1997, respectively. General and administrative expenses
increased $34.1 million in fiscal 1999 and $3.6 million in fiscal 1998, when
compared to respective prior fiscal years. In fiscal 1999, the Company revised
its estimates of the recoverability of its South American receivables and
provided additional reserves of

                                       19
<PAGE>
$8.9 million. Additionally in fiscal 1999, following a review of all receivables
on the Company's books other than South American receivables, the Company
increased its bad debt reserves by $6.0 million. The Company incurred
$9.3 million of extra expenses related to the additional employees and the
increased use of consultants associated with business development, finance,
quality systems, information technologies, and legal. The Company had expenses
of $1.2 million in the fourth quarter of fiscal year 1999, associated with
litigation expenses related to the pending class action lawsuit and shareholder
derivative action. See Note 10 "Non-Ordinary Charges and Expenses" of Notes to
Consolidated Financial Statements. The increase in fiscal 1998 as a percentage
of sales and in dollar volume from fiscal 1997 to fiscal 1998 was due to higher
staffing levels.

    Goodwill amortization totaled $2.0, $2.2 and $1.0 million in fiscal 1999,
1998 and 1997, respectively. Goodwill amortization decreased $0.2 million in
fiscal 1999 and increased $1.2 million in fiscal 1998, when compared to
respective prior fiscal years. The decrease in fiscal 1999 is due to having
fully amortized a goodwill asset from an older acquisition. The increase in
fiscal 1998 resulted from the amortization of goodwill expenses associated with
acquisitions of Southern Cats, CT Solutions and ONES in fiscal 1998. See Note 4
"Acquisitions" of Notes to Consolidated Financial Statements.

    The Company also recognized a pre-tax charge to operations of $1.4 million
for the purchase of acquired in-process research and development related to the
acquisition of UGM. This charge was computed using the percent complete method,
discounting the relevant future cash flows at 40% reflecting the weighted
average cost of capital and the specific risks associated with each in-process
product. See Note 4 "Acquisitions" of Notes to Consolidated Financial
Statements.

    Restructuring charges totaled $4.0 million in fiscal 1999. On September 27,
1998, the Company concluded a comprehensive review of its international
operations and decided to restructure its European and South American
businesses. As a result, the Company recorded charges in fiscal 1999 of $2.5 and
$0.8 million, respectively. In June of 1999, the Company also decided to
restructure its ADAC Medical Technologies ("AMT") business and recorded a charge
of $0.5 million. See Note 10 "Non-Ordinary Charges and Expenses". In
September 1999, the Company decided to carry out additional restructuring of its
South American business and recorded a charge of $0.5 million and recovered
$0.2 million of European restructuring charges due to revised estimates related
to employee severance costs. The fiscal 1999 restructuring costs were comprised
of $2.3 million for severance expenses, $0.8 million for legal and consulting
costs, $0.2 million for facilities and $0.8 million for other costs associated
with the restructuring. As of October 3, 1999, $2.0 million remained in the
accrual for restructuring costs comprised of $1.1 million for severance
expenses, $0.5 million for legal and consulting, $0.2 million for facilities and
$0.2 million for other costs associated with the restructuring. The Company
currently anticipates that these restructuring costs will be paid during fiscal
2000. See Note 3 "Restructuring Charges" of Notes to Consolidated Financial
Statements.

    In fiscal 1998, the Company recognized non-ordinary pre-tax charges of
approximately $1.3 million to write off capitalized expenses relating to
specific acquisitions activities which were discontinued by the Company and
$1.9 million for discontinuing the Company's physician network services
business. See Note 10 "Non-Ordinary Charges and Expenses" of Notes to
Consolidated Financial Statements.

    Other expense, net, which primarily consists of interest expense and foreign
currency transaction gains and losses, totaled $4.5, $4.3 and $5.3 million in
fiscal 1999, 1998 and 1997, respectively. Other expense, net, increased
$0.2 million in fiscal 1999 and decreased $1.0 million in fiscal 1998, when
compared to respective prior fiscal years. The fiscal 1999 increase was due to
increased interest expense incurred on higher debt levels. The 1998, decrease
was primarily due to foreign currency gains in fiscal 1998, partially offset by
increased interest expense.

                                       20

INCOME TAXES

    The Company's effective tax rate for fiscal years 1999, 1998 and 1997 was
23%, 39% and 39%, respectively. The principal reasons for the difference between
the statutory tax rate of 35% and the effective tax rate of 23% in fiscal 1999
related to (1) changes in assumptions regarding the realization of certain
deferred tax assets, and (2) state income taxes and certain permanent
differences. Fiscal 1998 and 1997 effective tax rates were approximately equal
to the Company's statutory federal and state tax rates after utilization of tax
credits. The Company currently expects the fiscal 2000 effective tax rate to be
between 35% and 40%.

LIQUIDITY AND CAPITAL RESOURCES

    The Company believes its available cash and cash equivalents, cash to be
generated primarily from operations, and its available credit lines, will
provide adequate funds to finance the Company's operations in fiscal 2000. If
necessary, the Company will seek to increase its credit lines to support the
Company's future growth. There can be no assurance that credit lines sufficient
to satisfy the Company's cash requirements will be available on terms acceptable
to the Company, if at all.

    Cash provided by operating activities was $6.2 million in fiscal 1999. The
primary source of cash was the net loss from operations of $33.6 million, which
includes $53.5 million (net) of non-cash charges. Net changes in operating
assets and liabilities of $13.6 million reduced the amount of cash otherwise
provided by operating activities. Cash of $27.3 million was provided by the
decrease in inventories primarily due to a work-down of finished goods
inventory. These sources of cash were partially offset by the $25.1 million net
increase in accounts receivable due to a decrease in accounts receivable sold to
third party finance companies and, to a lesser degree, increased sales for
fiscal 1999 when compared to fiscal 1998.

    Cash provided by operating activities was $5.3 million in fiscal 1998. The
primary source of cash from operations was the net income of $7.4 million with
non-cash charges of $33.8 million. The non-cash charges primarily consist of
amounts provided for discontinued products, and depreciation and amortization.
These sources of cash were partially offset by a $30.8 increase in inventories.

    Cash of $37.0 million was used for investing activities in fiscal 1999. This
activity consisted primarily of $17.0 million for the UGM acquisition (see
Note 4 "Acquisitions" of Notes to Consolidated Financial Statements),
$9.7 million capital equipment expenditures, and $8.9 million increase in
capitalized software. Capital expenditures were primarily for internal use
engineering and sales demonstration equipment and equipment to support new
enterprise software being installed for the sales and service groups. The
increase in capitalized software is from the continued investment in the next
generation of software products. Cash of $18.2 million was used for investing
activities in fiscal 1998. This activity consisted principally of capitalized
software and intangibles from the acquisitions of CT Solutions and ONES.

    Financing activities provided $32.1 million of cash in fiscal 1999. This was
primarily attributable to $28.6 million of increased borrowings and
$3.9 million of proceeds from common stock issued to employees under the
Company's employee stock purchase and option plans. Financing activities
provided $12.7 million of cash in fiscal 1998. This was primarily attributable
to $12.8 million of proceeds from common stock issued to employees under the
Company's employee stock purchase and option plans.

    The Company has a $75.0 million revolving credit facility with a bank
syndicate. The credit facility offers borrowings in either U.S. dollars or in
foreign currencies and expires on March 29, 2002. The Company pays interest and
commitment fees on its borrowings based on its debt level in relation to its
cash flow. Commitment fees range from 0.25% to 0.75% of unused commitment and
interest rates are based on the bank prime rate or LIBOR plus rates ranging from
1.0% to 2.5%. At October 3, 1999, the Company had $23.4 million available for
borrowing under this facility. Borrowings are collateralized by all of the
Company's assets, and the Company is required to comply with certain financial
and other covenants. In February 1999, the Company delayed delivering financial
statements and related information to its banks in connection with the
restatement occurring at that time. This constituted a default under the
facility. In

                                       21
<PAGE>
May 1999, the Company again delayed delivering financial statements and related
information to its banks in connection with the delayed public release of second
quarter financials for fiscal 1999. This also constituted a default under the
facility. In both cases, the banks waived the defaults and consented to an
extension of time required to provide such information. The Company has since
delivered all required information within the time frames required by the
covenants. In addition, the results of the Company's operations in the second
and third quarters of fiscal 1999 caused the Company to be out of compliance
with all financial covenants in the facility. The banks waived this default for
the second quarter of fiscal 1999. The Company amended the facility on
August 17, 1999, modifying the financial covenants to be more reflective of the
Company's recent financial performance. The Company was in compliance with all
financial covenants in the facility on October 3, 1999.

    The Company's liquidity is affected by many factors, some based on the
normal ongoing operations of the business and others related to the
uncertainties of the industry and global economies. Although the Company's cash
requirements will fluctuate based on the timing and extent of these factors,
management believes that cash to be generated from operations, together with the
liquidity provided by existing cash balances and borrowing capability, will be
sufficient to satisfy commitments for capital expenditures and other cash
requirements for the next fiscal year. However, the Company may need to increase
its sources of capital through additional borrowings or the sale of securities
in response to changing business conditions or to pursue new business
opportunities. There can be no assurance that such additional sources of capital
will be available on terms favorable to the Company, if at all.

RECENT PRONOUNCEMENTS

    In June 1998, Statement of Financial Accounting Standard 133, "Accounting
for Derivative Instruments and Hedging Activities" ("FAS 133"), was issued and
is effective for fiscal years commencing after June 15, 2000. The Company will
comply with the requirements of FAS 133 in fiscal year 2001. Currently the
Company does not hold any derivative instruments or engage in any hedging
activities.

BUSINESS CONSIDERATIONS

    From time to time, the Company may disclose, through press releases, filings
with the SEC or otherwise, certain matters that constitute forward looking
statements within the meaning of the Federal securities laws. These statements,
including the forward looking statements contained in this Form 10-K, are
subject to a number of risks and uncertainties, which could cause actual results
to differ materially from those projected, including without limitation those
set forth below. These forward looking statements include statements concerning
the Company's future bookings, revenue, expenses and earnings, the establishment
of additional reserves and the recording of non-ordinary charges. Factors that
could cause actual results to differ materially from those contained in such
forward-looking statements include, but are not limited to, the existence of
significant competition in each of the business segments in which the Company
conducts business; the impact of Year 2000 on the Company's results; the
Company's dependence on successfully developing, introducing and commercializing
new products and developing enhancements to existing products; the
collectibility of the Company's receivables; changes to the Company's operating
structure and charges and dislocations that may result therefrom; the impact of
international economic conditions on the Company's business; and a number of
factors that can introduce variability in the Company's operating results,
including the timing of product orders, shipments, and installations. Further
information on these and other factors is found below. All forward-looking
statements are based on information available to the Company on the date hereof,
and the Company assumes no obligation to update such statements.

LITIGATION

    Commencing in December 1998, a total of eleven class action lawsuits were
filed in federal court by or on behalf of stockholders who purchased Company
stock between January 10, 1996 and December 28, 1998. These actions name as
defendants the Company and certain of its present and former officers and

                                       22
<PAGE>
directors. The complaints allege various violations of the federal securities
laws in connection with the restatement of the Company's financial statements
and seek unspecified but potentially significant damages. In April 1999, these
actions were ordered consolidated and, in July 1999, the plaintiffs filed a
consolidated amended complaint. The Company intends to contest this action
vigorously. A stockholder derivative action, purportedly on behalf of the
Company and naming as defendants Company officers and directors was also filed
in state court seeking recovery for the Company based on stock sales by these
defendants during the above time period. The Company is also a defendant in
various legal proceedings incidental to its business.

    While it is not possible to determine the ultimate outcome of these actions
at this time, management is of the opinion that any liability resulting from
these claims would not have a material adverse effect on the Company's
consolidated financial position. However, the outcome of these actions could
have a material adverse effect on the Company's results of operations or cash
flows.

    The Company has been informed that the United States Securities and Exchange
Commission (SEC) has issued a Formal Order of Private Investigation in
connection with matters relating to the Company's previously announced
restatement of its financial results for 1996, 1997 and the first three quarters
of 1998. The Company is continuing to cooperate with the SEC. The Company is
unable to predict the outcome of the investigation at this time.

SOUTH AMERICAN OPERATIONS

    As previously disclosed in the Company's Form 10-Q for the quarter ended
April 4, 1999, a significant number of the Company's customers in its principal
South American markets of Brazil, Argentina and Colombia are delinquent in
making periodic payments due under the terms of sales previously made to them,
many of which were supported by third-party financing arrangements that involve
full or partial recourse to the Company. Deteriorating economic conditions and
currency devaluations occurring primarily during fiscal 1999, and ineffective
monitoring of delinquencies and collection efforts by the Company, may have all
contributed to delays in the collection of accounts receivable from customers in
these markets. During fiscal 1999, the Company undertook renewed collection
efforts and completed an evaluation of each receivable balance and recourse
obligation to determine the level of reserves required for these customers. As a
result of this evaluation, the Company has revised its estimate of the
recoverability of its South American receivables and recourse obligations and
provided additional reserves of $8.9 million during fiscal 1999, of which
$1.8 million was recorded in the fourth quarter. These charges resulted in total
reserves of $9.8 million against total gross receivables and recourse
obligations for South America of approximately $12.8 million. Consequently, at
October 3, 1999, the Company has net South American receivables of $1.8 million
and recourse contingencies of $1.2 million.

GOVERNMENT REGULATION

    The design, clinical activities, manufacturing, labeling, distribution,
sale, marketing, advertising and promotion of the company's products are subject
to extensive and rigorous governmental regulation in the United States and
foreign countries. In the United States and certain foreign countries, the
process of obtaining and maintaining required regulatory clearances or approvals
is lengthy, expensive and uncertain. There can be no assurance that any
necessary clearance or approval will be granted the Company or that FDA or other
regulatory agency review will not involve delays adversely affecting the
Company. In addition, a failure to comply with applicable regulatory
requirements could result in enforcement actions including Warning Letters, as
well as civil penalties, injunctions, suspensions or losses of regulatory
clearances, product recalls, seizure or administrative detention of products,
operating restrictions through consent decrees or otherwise, and criminal
prosecution, which could have a material adverse effect upon the Company.

    Following an inspection in mid-1997, Cortet, Inc., which the Company
acquired in May 1997, received a Warning Letter from the FDA concerning
inspectional observations relating to the adequacies of

                                       23
<PAGE>
Cortet's quality assurance system. Cortet responded to the observations and the
Warning Letter and received correspondence from the FDA's Florida District
Office indicating that Cortet's responses appeared to adequately address the
FDA's concerns. In mid-1998, the State of California, under a contract with the
FDA, completed a routine inspection of ADAC's facility in Milpitas, California.
The state investigator issued a FDA Form 483 containing observations of
non-compliance of the recently implemented QSR. The state investigator also
placed a temporary shipment hold on Pinnacle(3) pending the Company
satisfactorily responding to the State's concerns regarding the Company's
quality systems. The Company promptly responded to the FDA and the State and
initiated a number of corrective actions. The State lifted the Pinnacle(3)
shipment hold on August 28, 1998 and, in September 1998, ADAC received a letter
from the FDA indicating that the Company had adequately responded to the FDA's
concerns. Although the Company was deemed to have adequately responded to the
State and FDA following the foregoing inspections, the Company is responsible
for the full implementation of all corrective actions. In addition, as all
companies are, the Company remains subject to periodic inspections in the future
and there can be no assurance as to the timing or outcome of any subsequent
inspection. The scope of any re-inspection could be more comprehensive than the
inspections of Cortet and the Company's Milpitas facility, and there can be no
assurance that the FDA, upon re-inspection, will deem the Company's corrective
actions to be adequate or that additional corrective action, in areas not
addressed in the Warning Letter or the Form 483, will not be required. Any
failure by the Company to fully implement the required corrective actions or to
comply with any other applicable regulatory requirements could have a material
adverse effect on the Company's ability to continue to manufacture and
distribute its products, and in more serious cases, could result in seizure,
recall, injunction and/or civil fines. Any of the foregoing, would have a
material adverse effect on the Company.

    The Company is also subject to FTC restrictions on advertising and numerous
federal, state and local laws relating to such matters as safe working
conditions, manufacturing practices, environmental protection and disposal of
hazardous substances. Changes in existing requirements, adoption of new
requirements or failure to comply with applicable requirements could have a
material adverse effect on the Company.

COMPETITION

    The markets served by the Company are characterized by rapidly evolving
technology, intense competition and pricing pressure. There are a number of
companies that currently offer, or are in the process of developing, products
that compete with products offered by the Company. Some of the Company's
competitors have substantially greater capital, engineering, manufacturing and
other resources than the Company. These competitors could develop technologies
and products that are more effective than those currently used or marketed by
the Company or that could render the Company's products obsolete or
noncompetitive, which could have a material adverse effect on the Company's
business.

DEPENDENCE ON NEW PRODUCTS AND PRODUCT ENHANCEMENTS

    ADAC's success is dependent upon the successful development, introduction
and commercialization of new products and the development of enhancements to
existing products. Because the markets in which the Company competes are highly
competitive, the Company must continue to develop and successfully commercialize
innovative new products and product enhancements such as SKYLight, C-PET, Forte,
MCD-PET, MCD/AC-PET and ENVOI in order to pursue its growth strategy. The
development of new products and product enhancements entails considerable time
and expense, including research and development costs, and the time, expense and
uncertainty involved in obtaining any necessary regulatory clearances. Failure
of the Company to develop, market and sell new products and enhancements
effectively in future periods could have a material adverse effect on the
Company's results of operations and financial condition.

                                       24
<PAGE>
FUTURE OPERATING RESULTS

    The Company's future operating results may vary substantially from period to
period. The timing and amount of revenues are subject to a number of factors
that make estimation of revenues and operating results prior to the end of the
quarter uncertain. The timing of revenues can be affected by delays in product
introductions, shipments and installation scheduling, as well as general
economic and industry conditions. Furthermore, of the orders received by the
Company in any fiscal quarter, a disproportionately large percentage has
typically been received and shipped toward the end of that quarter, which is
typical for the industry. Accordingly, results for a given quarter can be
adversely affected if there is a substantial order shortfall late in that
quarter. In addition, the Company's bookings and backlog cannot necessarily be
relied upon as an accurate predictor of future revenues as the timing of such
revenues is dependent upon completion of customer site preparation and
construction, installation scheduling, receipt of applicable regulatory
approvals, customer financing and other factors. Accordingly, there can be no
assurance that orders will mature into revenue. The Company has accounts
receivable due from customers in South America. Recent changes in economic
conditions in that region, including the devaluation of Brazilian currency, may
adversely affect the Company's ability to collect these accounts receivable. The
Company recorded reserves during 1999 relating to a majority of these accounts
receivable. If the Company were unable to collect the remaining portion of these
accounts receivable its future results of operations could be adversely
affected.

MATERIAL WEAKNESSES IN INTERNAL CONTROLS

    After completion of their audit of the Company's fiscal 1998 consolidated
financial statements, the Company's independent accountants reported to the
Company's audit committee that they had found material weaknesses in the
Company's internal accounting controls. Following receipt of this report, the
Company retained a nationally recognized accounting firm as consultant and
internal auditor other than its independent accountants to review its controls.
That firm has developed a number of recommendations and has been retained to
assist the Company in implementing certain process improvements. The Company
believes that it has already taken steps to remedy certain weaknesses in its
control functions, and that improvements already in place, coupled with
improvements the Company plans to make in the near future, are expected to
substantially improve the timeliness and accuracy of the Company's internal
financial reporting and monitoring functions.

RISKS RELATED TO ACQUISITIONS

    In the past three years, the Company has acquired a number of businesses,
and anticipates that it may continue to acquire businesses whose products and
services complement the Company's businesses. Acquisitions involve numerous
risks, including, among other things, difficulties in successfully integrating
the businesses (including products and services, as well as sales and marketing
efforts), failure to retain existing customers or attract new customers to the
acquired business operations, failure to retain key technical and management
personnel, coordinating geographically separated organizations, and diversion of
ADAC management attention. These risks, as well as liabilities of any acquired
business (whether known or unknown at the time of acquisition), could have a
material adverse effect on the results of operations and financial condition of
the Company, including adverse short-term effects on its reported operating
results. The Company seeks to mitigate these risks by taking reserves when
appropriate in connection with these acquisitions. In addition, the Company has
in the past and may in the future issue stock as consideration for acquisitions.
Future sales of shares of the Company's stock issued in such acquisitions could
adversely affect or cause fluctuations in the market price of the Company's
Common Stock.

YEAR 2000 COMPLIANCE

    The following statements are a "Year 2000 Readiness Disclosure" within the
meaning of the Year 2000 Information and Readiness Disclosure Act. Many
currently installed computer systems and software products are coded to accept
only 2 digit entries in the date code field. Beginning in the Year 2000, these
date code fields will need to accept 4 digit entries to distinguish 21st century
dates from 20th century dates. Systems that do not properly recognize such
information could generate erroneous data or cause a system to fail. As a
result, computer systems and/or software used by many companies may need to be
upgraded to comply with such Year 2000 requirements. The Company has utilized
both internal and external resources to identify, correct or reprogram, and test
its internal systems, for Year 2000 compliance. Although management is
continuing to assess the expense associated with internal Year 2000 compliance,
the Company does not believe that the costs incurred in connection with its Year
2000 compliance program will have a material adverse effect on the Company's
results of operations or financial condition.

    The Company has completed an assessment and analysis of its internal
information technology systems, software and manufacturing equipment. The
Company has implemented the significant system changes needed to correct its
internal Year 2000 issues. While the Company currently expects that the Year
2000 will not pose significant internal operational problems, failure to fully
identify all Year 2000 dependencies in the Company's systems could have a
material adverse effect on the Company's results of operations.

    The Company has established a program to assess its products to ensure that
they are Year 2000 compliant. To monitor this program and to inform customers
about the Year 2000 issues with respect to its products, the Company has created
a website at www.adaclabs.com/about/year20001.html. This website identifies the
status of Year 2000 compatibility of its products, including products that are
Year 2000 compliant, products that need software updates, products that require
hardware upgrades, and products that cannot be made Year 2000 compliant.

    The Company is selling, or providing under warranty or service contracts,
software license upgrades to update its installed base to make its products Year
2000 compliant. For older equipment which the Company no longer manufactures,
the Company will sell hardware upgrades to its customers which will address the
Year 2000 compliance where possible. The Company has contacted by mail all
customers which require computer hardware upgrades, and has also posted
information relating to Year 2000 compliance for its products on the Company's
website as described above.

    The Company has completed gathering information from its suppliers and
vendors to determine the extent to which the Company's capabilities are
vulnerable to failure by those third parties to remedy their own Year 2000
issues. The Company does not believe that there will be any material adverse
effect on the Company's results of operations. However, there is no guarantee
that the systems and products of other companies on which the Company relies
will be timely converted or that they will not have a material adverse effect on
the Company.

    The Company has implemented a Year 2000 contingency plan and incurred Year
2000 costs of approximately $1.2 million. This amount does not include any
potential costs related to any customer or other claim. In addition, these costs
are based on current assessments of the activities already completed and are
subject to any changes necessary, after the Year 2000 transition occurs.

    Actual results may vary as a result of number of factors, including those
described herein. There can be no assurance that the Company has successfully
modified all such products, services and systems to comply with Year 2000
requirements, which failure could have a material adverse effect on the
Company's operating results.

    In addition, the Company has ensured that the software included in its
products and other systems is Year 2000 compliant. Failure (or perceived
failure) of such products to be Year 2000 compliant could significantly
adversely affect sales of such products, which could have a material adverse
effect on the

                                       26
<PAGE>
Company's results of operations and financial condition. In addition, the
Company believes that the purchasing patterns of customers and potential
customers may be affected by Year 2000 issues in a variety of ways. Potential
customers may choose to defer purchasing Year 2000 compliant products until they
believe it is absolutely necessary, thus resulting in potentially stalled market
sales within the industries in which the Company competes. Conversely, Year 2000
issues may cause other companies to accelerate purchases, thereby causing an
increase in short-term demand and a consequent decrease in long-term demand for
the Company's products. Additionally, Year 2000 issues could cause a significant
number of companies, including current Company customers, to reevaluate their
current system needs, and as a result consider switching to other systems or
suppliers. Any of the foregoing could result in a material adverse effect on the
Company's business, operating results and financial condition.

HEALTH CARE REFORM; REIMBURSEMENT AND PRICING PRESSURE

    There is significant concern today about the availability and rising cost of
health care in the United States. Cost containment initiatives, market pressures
and proposed changes in applicable laws and regulations may have a dramatic
effect on pricing or potential demand for medical devices, the relative costs
associated with doing business and the amount of reimbursement by both
government and third party payors, which could have a material adverse effect on
the Company's results of operations.

INTELLECTUAL PROPERTY RIGHTS

    The Company's success depends in part on its continued ability to obtain
patents, to preserve its trade secrets and to operate without infringing the
proprietary rights of third parties. There can be no assurance that pending
patent applications will mature into issued patents or that third parties will
not make claims of infringement against the Company's products or technologies
or will not be issued patents that may require payment of license fees by the
Company or prevent the sale of certain products by the Company.

RELIANCE ON SUPPLIERS

    Certain components used by the Company to manufacture its products such as
the sodium iodide crystals used in the Company's Medical Systems are presently
available from only one supplier. The Company also relies on several significant
vendors for hardware and software components for its health care information
systems products. The loss of any of these suppliers, including any
single-source supplier, would require obtaining one or more replacement
suppliers as well as potentially requiring a significant level of hardware and
software development to incorporate the new parts into the Company's products.
Although the Company has obtained insurance to protect against loss due to
business interruption from these and other sources, there can be no assurance
that such coverage would be adequate.

PRODUCT LIABILITY

    Although the Company maintains product liability insurance coverage in an
amount that it deems sufficient for its business, there can be no assurance that
such coverage will ultimately prove to be adequate or that such coverage will
continue to remain available on acceptable terms, if at all.

VOLATILITY OF STOCK PRICE

    The market price of the Company's Common Stock is and is expected to
continue to be subject to significant fluctuations in response to variations in
anticipated or actual operating results, market speculation, announcements of
new products or technology by the Company or its competitors, changes in
earnings estimates by the Company's analysts, trends in the health care industry
in general and other factors, many of which are beyond the control of the
Company. In addition, broad market fluctuations as well as general economic or
political conditions or initiatives, such as health care reform, may adversely
impact the market price of the Common Stock regardless of the Company's
operating results.

MARKET RISK

FOREIGN CURRENCY EXCHANGE

    The Company faces exposure to adverse movements in foreign currency exchange
rates. These exposures may change over time as business practices evolve and
could have a material adverse impact on the Company's financial results. The
Company's primary exposures relate to non-U.S. dollar denominated sales in
Europe and Canada where the principal currencies are Dutch Guilders, German
Deutsche Marks and Canadian Dollars. Currently, the Company does not hedge
foreign currency exchange rate exposures.

INTEREST RATE RISK

    The Company's exposure to market risk for changes in interest rates relates
primarily to the Company's cash equivalents and notes payable to banks. The
Company's cash equivalents include highly liquid instruments with an original
maturity of three months or less. The Company primarily enters into debt
obligations to support general corporate purposes, including working capital
requirements, capital expenditures, and acquisitions. The Company is subject to
fluctuating interest rates that may impact, adversely or otherwise, its results
of operations or cash flows for its variable rate notes payable and cash
equivalents.

    The estimated fair value of the Company's cash and cash equivalents
approximates their carrying values based on the short maturities of these
financial instruments. The estimated fair value of the Company's debt
obligations approximates their carrying values based on rates currently
available to the Company for debt with similar terms and remaining maturities.
Although payments under certain of the Company's operating leases for its
facilities are tied to market indices, the Company is not exposed to material
interest rate risk associated with these obligations. The Company does not hedge
interest rate change exposures.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

FISCAL YEAR

    The Company's fiscal year ends on the Sunday closest to September 30. Fiscal
1999 included 53 weeks, while fiscal 1998 and 1997 included 52 weeks.

FINANCIAL STATEMENT PRESENTATION

    The consolidated financial statements include the accounts of ADAC
Laboratories and its wholly owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in the financial statements.
Certain amounts in the prior years' financial statements have been reclassified
to conform to the fiscal 1999 presentation.

FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS

    The Company's foreign subsidiaries' functional currencies are considered to
be their respective local currencies. Adjustments that arise in translating
their financial statements into U.S. dollars are included as a separate
component of shareholders' equity in the consolidated balance sheets. Gains and
losses from foreign currency transactions have been immaterial for the periods
presented.

REVENUE RECOGNITION

    Beginning in fiscal 1999, the Company adopted Statement of Position 97-2
("SOP 97-2") "Software Revenue Recognition," as amended by Statements of
Position 98-4 "Deferral of the Effective Date of a Provision of SOP 97-2,
Software Revenue Recognition" and 98-9 "Modification of SOP 97-2 with Respect to
Certain Transactions". The adoption of SOP 97-2, as amended, applied to revenue
recognized in the Company's RTP and HCIS businesses.

    Medical Systems: Revenues related to the Company's Medical Systems business
product sales are recognized upon shipment to the customer, at which time title
and risk of ownership pass. In circumstances where customers request the product
to be temporarily stored or shipped to a site other than where it is intended to
be used, revenue is recognized where the customer makes a written request based
on its circumstances which prevent immediate on site delivery, title and risk of
ownership pass to the customer, a significant down payment is received, and
delivery to the end use site is generally expected within a specified period.
Estimated provisions for installation and warranty are accrued upon revenue
recognition for the product sales. Revenues related to Medical Systems services
are recognized ratably over the relevant contractual period or as the services
are performed. Medical Systems services revenue billed but unearned is included
on the consolidated balance sheets as deferred revenue.

    Radiation Therapy Products ("RTP") and Health Care Information Systems
("HCIS") Cardiology: Revenues related to the RTP and HCIS Cardiology businesses
are derived from software licenses, computer hardware sales, related
implementation, training and support services and maintenance contracts.
Revenues for software licenses are recognized at the shipment date. Revenues for
computer hardware sales are recognized at the time of shipment. When software is
sold in conjunction with hardware, revenue is recognized when both software and
hardware have been shipped. The Company's obligations subsequent to shipment
primarily relate to implementation, training and maintenance, such revenues are
recognized as services are performed based on vendor specific objective evidence
of fair value. Revenues from support services and maintenance contracts are
recognized ratably over the relevant contractual period.

the HCIS business are derived from software licenses, computer hardware sales,
related implementation, training and support services and maintenance contracts.
The installation of HCIS systems typically occurs over a nine to twelve month
period. During fiscal 1997 and 1998, revenues in the HCIS business were
recognized as described in the preceding paragraph. Adoption of SOP 97-2, as
amended, in fiscal 1999 resulted in changes in revenue recognition for the
Company's HCIS business. Commencing with contracts entered into in fiscal 1999,
HCIS recognized revenue for software licenses, computer hardware, implementation
and training under the percentage of completion method, based on the ratio of
labor costs incurred versus total estimated labor costs. Revenues from support
services and maintenance contracts are recognized ratably over the relevant
contractual period. Renewal of software licenses are recognized over the renewal
period.

RESEARCH AND DEVELOPMENT

    Research and development expenditures are charged to operations as incurred.

INCOME TAXES

    Under the asset and liability method of accounting for income taxes,
deferred tax assets and liabilities are recognized for the future tax
consequences attributable to temporary differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates expected to apply to taxable income in the years in which
those temporary differences are expected to be recovered or settled. The effect
on deferred tax assets and liabilities of a change in tax rate is recognized as
income in the period that includes the enactment date. A valuation allowance is
established if it is more likely than not that the related deferred tax assets
will not be realized.

INCOME (LOSS) PER SHARE

    Basic net income (loss) per share has been computed using the weighted
average number of common shares outstanding. Diluted net income (loss) per share
includes the effect of common stock options and warrants using the treasury
stock method, if dilutive. The calculation of basic and diluted net income
(loss) per share is as follows:

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CASH EQUIVALENTS

    All highly liquid investments purchased with an original maturity of three
months or less are considered cash equivalents.

CONCENTRATION OF CREDIT RISK

    The Company sells its products to hospitals and clinics worldwide. The
Company performs ongoing credit evaluations of its customers and generally does
not require collateral. The Company maintains allowances for potential credit
losses. The Company invests any excess cash on deposits with a major investment
bank. The Company has not experienced any losses on these deposits.

RELIANCE ON CERTAIN SUPPLIERS

    Certain components and services used by the Company to manufacture and
develop its products are presently available from only one or a limited number
of suppliers or vendors. The loss of any of these suppliers or vendors would
potentially require a significant level of hardware and/or software development
to incorporate the products or services from new suppliers or vendors into the
Company's products. Although the Company has obtained business interruption
insurance to protect against such losses, there is no assurance that such
coverage would be adequate.

INVENTORIES

    Inventories are stated at the lower of standard cost (which approximates
cost on a first-in, first-out basis) or market. Inventory reserves are recorded
in the period when slow moving or obsolete materials are first identified.

SERVICE PARTS

    Parts used for servicing installed equipment are stated at cost and
depreciation is computed over the estimated useful life. During fiscal 1999, the
Company reviewed the composition of its capitalized field service inventory and
the estimated collective useful life of this asset. As a result of this review,
effective beginning in the fourth quarter of fiscal 1999, the Company revised
its method of computing depreciation on its existing service parts inventory
from 10 years using the declining balance method to 5 years on the straight line
method. Depreciation on all service parts capitalized in the future will be
computed over 7 years on the straight line method. These revisions had an
immaterial effect on the results of operations. The Company will continue to
monitor recoverability of the collective asset under SFAS No. 121 "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of."

FIXED ASSETS

    Major additions and improvements are capitalized at cost, while maintenance
and repairs which do not improve or extend the life of the respective assets are
expensed as incurred. When assets are retired or otherwise disposed of, the
costs and related accumulated depreciation are removed from the financial
statements, and any gain or loss on disposal is included in the consolidated
statements of operations. Depreciation on fixed assets, other than leasehold
improvements, is computed on a straight-line basis over their estimated useful
lives (3-5 years). Leasehold improvements are amortized on a straight-line basis
over the lesser of their estimated useful lives or the remaining term of the
related leases.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CAPITALIZED SOFTWARE FOR PRODUCTS

    Costs related to the conceptual formulation and design of software products
to be licensed or sold are expensed as research and development. Costs incurred
subsequent to establishing technological feasibility of software products to be
licensed or sold are capitalized. Amortization of capitalized software
development costs, which begins when products are available for general release
to customers, is computed using the greater of 1) the ratio that current gross
revenues bear to the total of current and anticipated future gross revenues; or
2) a straight-line basis over the expected product lives, generally estimated to
be three to seven years.

    Software costs capitalized during fiscal 1999, 1998 and 1997 were
approximately $8.9 million, $7.0 million and $4.5 million, respectively.
Amortization of capitalized development software costs during the fiscal 1999,
1998 and 1997 of approximately $3.2 million, $3.4 million and $3.2 million,
respectively, has been charged to cost of product revenues. Capitalized software
development costs relating to products which have not yet been released were
approximately $4.9 million at October 3, 1999. See Note 10, "Non-Ordinary
Charges and Expenses", relating to the write-off of LabStat capitalized
software.

INTERNAL USE SOFTWARE

    The Company adopted Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." Costs related to the
purchase, design, coding, testing and installation of internal use software are
capitalized. Amortization of internal use software costs, which begins when
software is used in business operations, is computed using the straight-line
method over the expected lives, generally estimated to be five years. Internal
use software costs capitalized during fiscal 1999 amounted to approximately
$0.9 million. The Company had no internal use software costs capitalized before
fiscal 1999.

INTANGIBLES

    Goodwill and other purchased intangibles, including acquired technology, are
capitalized and amortized on a straight-line basis over the estimated useful
life of the related asset (7-20 years). The Company evaluates the recoverability
of long-lived assets not held for sale by measuring the carrying amount of the
assets against the estimated undiscounted future cash flows associated with
them. At the time such flows are not sufficient to recover the carrying value of
such assets, the assets are adjusted to their fair values. Based on these
evaluations, there were no adjustments to the carrying value of long-lived
assets in fiscal 1999 or 1998.

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.

NOTE 3 RESTRUCTURING CHARGES

    On September 27, 1998, the Company concluded a comprehensive review of its
international operations and decided to restructure its European and South
American businesses. As a result, the Company recorded charges in fiscal 1999 of
$2.5 and $0.8 million, respectively. In June of 1999, the Company also decided
to restructure its ADAC Medical Technologies ("AMT") business and recorded a
charge of $0.5 million. In September 1999, the Company decided to carry out
additional restructuring of its South American Business and recorded a charge of
$0.5 million and recovered $0.2 million of European restructuring charges due to
revised estimates related to employee severance costs. The fiscal 1999
restructuring costs were comprised of $2.3 million for severance expenses,
$0.8 million for legal and consulting costs, $0.2 million for facilities and
$0.8 million for other costs associated with the restructuring. As of
October 3, 1999, $2.0 million remained in the accrual for restructuring costs
comprised of $1.1 million for severance expenses, $0.5 million for legal and
consulting, $0.2 million for facilities and $0.2 million for other costs
associated with the restructuring. The Company currently anticipates that these
restructuring costs will be paid during fiscal 2000.

NOTE 4 ACQUISITIONS

    On October 1, 1999, the Company acquired two related companies, UGM Medical
Systems Inc. and UGM Laboratories, Inc. (together "UGM") for $18.5 million. UGM
was an independent developer and manufacturer of PET equipment, for which the
Company has been its principal distributor. The acquisition was accounted for
using the purchase method of accounting and the results of UGM have been
included in the Company's financial statements subsequent to October 1, 1999.
The allocation of the purchase price to the tangible and identifiable intangible
assets acquired in connection with this acquisition was based on estimated fair
values as determined by management as follows:

</TABLE>

    The amortization of goodwill, acquired technology and workforce is being
computed on the straight-line basis. The Company also recognized a pre-tax
charge to operations of $1.4 million for the purchase of acquired in-process
research and development. This charge was computed using the percent complete
method, discounting the relevant future cash flows at 40% to reflect the
weighted average cost of capital and the specific risks associated with each
in-process product.

    The total purchase price consisted of cash of $18.0 million and transaction
costs of $0.5 million. Further, the Company may be required to pay additional
purchase price consideration and incur future compensation in amounts not

NOTE 5 CREDIT AND BORROWING ARRANGEMENTS

    The Company has a $75.0 million revolving credit facility with a bank
syndicate. The credit facility offers borrowings in either U.S. dollars or in
foreign currencies and expires on March 29, 2002. The Company pays interest and
commitment fees on its borrowings based on its debt level in relation to its
cash flow. Commitment fees range from 0.25% to 0.75% of unused commitment and
interest rates are based on the bank prime rate or LIBOR plus rates ranging from
1.0% to 2.5%. At October 3, 1999, the Company had $23.4 million available for
borrowing under this facility. Borrowings are collateralized by all of the
Company's assets, and the Company is required to comply with certain financial
and other covenants. In February 1999, the Company delayed delivering financial
statements and related information to its banks in connection with the
restatement occurring at that time. This constituted a default under the
facility. In May 1999, the Company again delayed delivering financial statements
and related information to its banks

in connection with the delayed public release of second quarter financials for
fiscal 1999. This also constituted a default under the facility. In both cases,
the banks waived the defaults and consented to an extension of time required to
provide such information. The Company has since delivered all required
information within the time frames required by the covenants. In addition, the
results of the Company's operations in the second and third quarters of
fiscal 1999 caused the Company to be out of compliance with all financial
covenants in the facility. The banks waived this default for the second quarter
of fiscal 1999. The Company amended the facility on August 17, 1999, modifying
the financial covenants to be more reflective of the Company's recent financial
performance. The Company was in compliance with all financial covenants in the
facility on October 3, 1999.

    Additional information with respect to such revolving lines of credit is as

LITIGATION

    Commencing in December 1998, a total of eleven class action lawsuits were
filed in federal court by or on behalf of stockholders who purchased Company
stock between January 10, 1996 and December 28, 1998. These actions name as
defendants the Company and certain of its present and former officers and
directors. The complaints allege various violations of the federal securities
laws in connection with the restatement of the Company's financial statements
and seek unspecified but potentially significant damages. In April 1999, these
actions were ordered consolidated and, in July 1999, the plaintiffs filed a
consolidated amended complaint. The Company intends to contest this action
vigorously. A stockholder derivative action, purportedly on behalf of the
Company and naming as defendants Company officers and directors was also filed
in state court seeking recovery for the Company based on stock sales by these
defendants during the above time period. The Company is also a defendant in
various legal proceedings incidental to its business.

    While it is not possible to determine the ultimate outcome of these actions
at this time, management is of the opinion that any liability resulting from
these claims would not have a material adverse effect on the Company's
consolidated financial position. However, the outcome of these actions could
have a material adverse effect on the Company's results of operations or cash
flows.

    The Company has been informed that the United States Securities and Exchange
Commission (SEC) has issued a Formal Order of Private Investigation in
connection with matters relating to the Company's previously announced
restatement of its financial results for 1996, 1997 and the first three quarters
of 1998. The Company is continuing to cooperate with the SEC. The Company is
unable to predict the outcome of the investigation at this time.

OTHER

    Under third party financing programs in effect prior to fiscal 1999, the
Company has contingent liabilities and certain recourse obligatons ranging from
10% to 100% of the amounts financed. As of October 3, 1999, the contingent
liability in excess of amounts accrued was $1.2 million.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

    The Company has in place performance bonds to shield certain customers from
potential damages that might result should the Company fail to deliver equipment
as promised. The amount of the bonds at October 3, 1999 was $0.6 million.

NOTE 7 CAPITAL STOCK

PREFERRED STOCK

    The Board of Directors is authorized to determine the rights and preferences
of the preferred stock, issuable in series. The Board of Directors may increase
or decrease the number of shares of any series of preferred stock, but not below
the number of shares of such series then outstanding.

COMMON STOCK

    In fiscal 1997 and 1995, the Board of Directors approved the issuance of
warrants to purchase up to 24,000 and 60,000 shares of common stock,
respectively, to a consulting firm as partial compensation for services rendered
and to be rendered. The exercise price for these warrants were $22.00 and
$11.88, respectively. The warrants were issued proportionately as services were
performed. As of October 3, 1999, 24,000 of these warrants were still
outstanding. For fiscal 1999, the warrants had no effect on the shares used for
calculation of diluted net loss per share. For fiscal 1998 and 1997, the effect
on shares used for calculation of diluted net income per share were 46,494 and
69,655, respectively.

NOTE 8 STOCK PLANS

STOCK OPTION PLANS

    The Company currently has two stock option plans for employees, the 1992
Stock Option Plan, as amended, and the 1999 Long-Term Incentive Plan which was
approved by the Company's stockholders in May 1999.

    The 1992 Stock Option Plan allows for non-qualified as well as incentive
options to be granted to employees, officers, consultants and others. Incentive
stock options must be granted at exercise prices of not less than fair market
value and expire within 10 years from the date of grant. Under the plan,
non-qualified stock options can have exercise prices of not less than 85% of
fair market value and also expire within 10 years of grant date.

    The 1999 Long-term Plan (the "1999 Plan") authorizes the issuance of
incentive stock options, non-qualifying stock options, restricked stock and
other incentives to directors, employees, and consultants. The exercise price
under the 1999 Plan can not be less than the fair market value per share on the
date of the grant. The term of the options are 10 years and generally vest over
a five-year period. The 1999 Plan limits the number of options that can be
granted to any one individual in any fiscal year to 300,000 shares.

    In fiscal 1999, the Company adopted the 1999 Supplemental Incentive Plan
("the Supplemental Plan"). The Supplemental Plan provides for the issuance of
options and restricted stock grants to directors, employees and consultants of
the Company. The restricted stock generally vests over four years. During fiscal
1999, the Board of Directors approved the issuance of 150,000 shares of common
stock under the supplemental plan. As of October 3, 1999, no shares have been
issued. The Company recognized $160,000 of compensation expense in fiscal 1999.

    In addition, the Company has a directors' stock option plan under which
options are granted to non-employee directors. Options under this plan are
granted for a period of 5 years from the date of grant at an option exercise
price equal to fair market value.

    A summary of the activity under these plans is as follows:

    Because the accounting method prescribed by SFAS 123 is not applicable to
options granted prior to October 3, 1995, the compensation cost reflected in the
pro forma amounts shown above may not be representative of the amounts to be
expected in future years.

    On November 10, 1997, HCIS adopted a stock option plan, the HCIS 1997 Stock
Option Plan, for its employees under which options may be granted. Total shares
of HCIS common stock reserved under the plan are 1,485,000. During fiscal 1999,
583,000 options were granted under the plan. Total options outstanding at
October 3, 1999 are 1,044,000, and total options available for grant are
441,000. The Company recognized $388,000 and $343,000 of compensation expense in
fiscal 1999 and 1998, respectively, related to this plan.

EMPLOYEE STOCK PURCHASE PLAN

    This plan, as amended, permits eligible employees to purchase common stock
through payroll deductions (which cannot exceed 10% of the employee's
compensation and cannot exceed 200 shares per employee per interim offering
period) at the lower of 85% of fair market value at the beginning of the
applicable offering period or at the end of each interim period. During fiscal
1999, 1998 and 1997, 75,000, 99,000 and 56,000 shares were issued at an average
price of $13.11, $16.22 and $15.05 per share, respectively. At October 3, 1999,
there were 263,000 share available under this plan.

PREFERRED SHARE PURCHASE RIGHTS PLAN

    In April 1996, the Company's Board of Directors adopted a Preferred Share
Purchase Rights Plan (the "Rights Plan"). Under the Rights Plan, a dividend of
one preferred share purchase right (a "Right") for each outstanding share of
common stock, of the Company was declared. Each Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Junior

NOTE 8 STOCK PLANS (CONTINUED)

Participating Preferred Stock, without par value (the "Preferred Stock"), at a
price of seventy dollars ($70.00) per one one-hundredth of a Preferred Share.
Each one one-hundredth of a share of Preferred Stock has designations and the
powers, preferences and rights, and the qualifications, limitations and
restrictions which make its value approximately equal to the value of a share of
common stock. In general, the Rights are exercisable upon the commencement of,
or announcement of an intention to make, a tender offer or exchange offer, the
consummation of which would result in the beneficial ownership by a person or
group of 15% or more of the Company's outstanding common stock. The Rights
expire in April 2006 unless the expiration date is extended or unless the Rights
are earlier redeemed by the Company.

    The Rights Plan is designed to provide an adequate opportunity for the
Company's Board of Directors to consider and evaluate all strategic alternatives
of the Company in the event an unsolicited attempt is made to acquire the
Company. The Rights are intended to enable all of the Company's shareholders to
realize the full value of their investment and to provide for fair and equal
treatment for all shareholders. The adoption of the Rights Plan will not, nor is
it intended to, prevent all takeover actions. The Rights were not distributed in
response to any proposal to acquire the Company.

    As of October, 3 1999, the Company has reserved a total of 5,415,000 shares
of common stock for issuance under its employee stock option, incentive and
purchase plans.

NOTE 9 RETIREMENT SAVINGS PLANS

    The Company maintains a qualified retirement plan, under the provisions of
Section 401(k) of the Internal Revenue Code, in which eligible employees may
participate. Substantially all participants in this plan are able to defer
compensation up to the annual maximum amount allowable under Internal Revenue
Service regulations. Additionally, the Company may match employee contributions
with discretionary amounts as may be determined by the Board of Directors.
During fiscal 1999, 1998 and 1997, the Company matched employee contributions up
to a maximum of $750, $500 and $500, respectively, per employee. The Company's
total contributions to the plan were $0.9, $0.3 and $0.3 million in fiscal 1999,
1998 and 1997, respectively.

    Effective June 1, 1999, the Company adopted an unfunded nonqualified
Deferred Compensation Plan (the "Plan"). The Plan permits certain employees,
consultants and directors to annually elect to defer a portion of their
compensation and qualifying gain with respect to exercises of eligible stock
options, until their retirement. The Plan allows for voluntary contributions by
the Company. There were no company contributions to the Plan in fiscal year
ending October 3, 1999. Total deferred compensation liabilities, under the Plan
were $159,000 as of October 3, 1999.

    To assist in funding the deferred compensation liability, the Company has
invested in corporate-owned life insurance policies. The cash surrender value of
these policies as of October 3, 1999 is $512,182 which are recorded as assets of
the Company in the consolidated balance sheet.

FISCAL 1999

INVENTORY AND RECEIVABLES

    During fiscal 1998, the Company began an examination of the performance,
profitability and prospects of its various business units as part of an overall
evaluation of its business and internal controls. In

NOTE 10 NON-ORDINARY CHARGES AND EXPENSES (CONTINUED)

connection with this examination, the Company identified issues relating to its
application of accounting principles and conducted a review of its asset
carrying values, accruals and expenses in historical financial periods, leading
to a restatement of reported financial results for fiscal 1996, fiscal 1997 and
the first three quarters of fiscal 1998. Following the restatement, the Company
continued to focus on its accounting systems and weaknesses in its internal
controls and the assessment of its business units. As part of this focus and
assessment, and against the background of increasing competition in certain of
the Company's markets, new product introductions by the Company and its
competitors, and its customers deferring purchasing decisions due to their
perceived Year 2000 compliance risks, the Company revised its estimates of
1) the recoverability of the Company's inventory to reflect its lower build
plans which resulted in increased levels of potentially excess and obsolete
inventory, 2) the collectibility of receivables, and 3) the value of certain
other assets carried on the Company's books.

    The Company also decided to close its AMT refurbishing facility in
Washington, Missouri, relocate the business to Milpitas, California, and
discontinue refurbishment of a number of lines of older nuclear medicine
equipment, the demand for which was declining. These fiscal 1999 decisions, as
well as existing market conditions, rendered obsolete substantial inventories of
equipment and parts.

    The Company's financial statements for fiscal 1999 include charges for these
changes in estimates of $13.6 million related to inventory and $6.0 million
related to receivables (excluding South American receivables).

SOUTH AMERICA

    As previously disclosed in the Company's Form 10-Q for the quarter ended
April 4, 1999 a significant number of the Company's customers in its principal
South American markets of Brazil, Argentina and Colombia are delinquent in
making periodic payments due under the terms of sales previously made to them,
many of which were supported by third-party financing arrangements that involve
full or partial recourse to the Company. Deteriorating economic conditions and
currency devaluations occurring primarily during fiscal 1999, and ineffective
monitoring of delinquencies and collection efforts by the Company, may have all
contributed to delays in the collection of accounts receivable from customers in
these markets. During fiscal 1999, the Company undertook renewed collection
efforts and completed an evaluation of each receivable balance and recourse
obligation to determine the level of reserves required for these customers. As a
result of this evaluation, the Company has revised its estimate of the
recoverability of its South American receivables and recourse obligations and
provided additional reserves of $8.9 million during fiscal 1999, of which
$1.8 million was recorded in the fourth quarter. These charges resulted in total
reserves of $9.8 million against total gross receivables and recourse
obligations for South America of approximately $12.8 million. Consequently, at
October 3, 1999, the Company has net South American receivables of $1.8 million
and recourse contingencies of $1.2 million.

LITIGATION

    In the fourth quarter of fiscal 1999, the Company incurred $1.2 million in
litigation expenses related to the pending class action lawsuit and stockholder
derivative action, see Note 6 "Commitments and Contingencies."

</TABLE>

    Of the amounts summarized above, substantially all of the inventory charges
were recorded in cost of product and service revenues in the statement of
operations. Substantially all the other charges were recorded in general and
administrative expense in the statement of operations.

    The Company has concentrated resources on continuing to improve its
accounting systems and internal controls, and has retained a nationally
recognized accounting firm as consultant and internal auditor. That firm has
developed a number of recommendations and has been retained to assist the
Company in implementing certain process improvements. Among other things, the
Company is attempting to integrate more closely its inventory procurement
procedures with the process of developing and introducing new products in order
to reduce the risk of substantial inventories being obsoleted by product
introductions. Furthermore, with respect to receivables, the Company is
improving its sales order and collection procedures related to product and field
service sales, and the sale of ancillary products which sales resulted in the
majority of the additional receivables reserves added during fiscal 1999.

FISCAL 1998

    On September 25, 1998, the Company concluded a comprehensive review of its
operations and decided to discontinue its physician network services business.
As a result, the Company recorded a

non-ordinary charge in the fourth quarter of fiscal 1998 of $1.9 million. The
Company decided to discontinue this business in the fourth quarter of fiscal
1998 and focus on its core businesses, since, among other things, this business
did not contribute meaningfully to the Company's results in fiscal 1998, and was
not expected to do so in future periods.

    In connection with the Company's evaluation of its operations, the Company
identified certain assets, consisting of capitalized consulting and banking
expenses relating to potential acquisitions, and determined it was appropriate
to write off these assets since the acquisitions would not occur. Accordingly,
the Company recorded a charge of $1.3 million in its results of operations for
the fourth quarter of fiscal 1998 for these assets.

    On February 10, 1998, the Company decided to discontinue the HCIS business
unit's LabStat product while retaining the laboratory support and maintenance
business. The decision was made after it was determined that continuing
development and marketing of LabStat was not in the best interest of the Company
and its shareholders and that all meaningful discussions with possible strategic
partners had ceased. This decision has allowed the Company to increase its focus
on the radiology business resulting in greater profitability for both HCIS and
ADAC as a whole.

    The Company's decision to discontinue LabStat resulted in a non-ordinary
discontinued product charge of $11.3 million. The charge is a consequence of the
Company determining that certain assets utilized in the development and
marketing of LabStat became impaired as a result of the Company's decision. The
discontinued business charge consisted principally of non-cash charges, includes
the write off of $4.9 million of capitalized software, $4.7 million of deferred
product costs, $0.6 million of fixed assets that were specifically utilized in
the LabStat product, $1.0 million in legal and other expenses and $0.1 million
in receivables.

    In connection with the Company's evaluation of its laboratory information
systems business, the Company also conducted an analysis of the recoverability
of certain assets utilized in the Company's Digital Subtraction Angiography
(DSA) business and determined it was appropriate to write off certain of these
assets. Accordingly, the Company included an impairment charge of $2.4 million
in its results of operations for the first quarter of fiscal 1998 related to
these assets. The decision to write off the DSA assets, consisting primarily of
inventory, was a result of the Company's decision to no longer market the
product due to steadily declining revenues. The combined a non-ordinary write
off for LabStat and DSA was $13.7 million.

FISCAL 1997

    In conjunction with the acquisition of Cortet in June 1997, the Company
identified certain assets, consisting of capitalized consulting and banking
expenses relating to other potential acquisitions, and determined it was
appropriate to write off these assets since the acquisitions would not occur. As
a result, the Company included a charge for $0.7 million in its results of
operations for the third quarter of fiscal 1997 for these assets.

    In fiscal 1999, changes in estimates reducing the benefit recorded for

    As of October 3, 1999, the Company had net operating loss carryforwards of
approximately $75.6 million available to offset future federal taxable income
and approximately $3.7 million available to offset future taxable income in
various foreign jurisdictions. Federal net operating loss carryforwards of
$15.7 million expire 2001, $30.8 million expire 2006 to 2010, $29.1 million
expire 2009 to 2014, and foreign operating loss carryforwards expire beginning
in fiscal year 2008. The federal operating loss carryforwards expiring in 2006
to 2010 are subject to certain restrictions on their annual utilization. The
Company also has business credit carryforwards of $6.4 million, of which
$0.4 million will expire in fiscal 2000, $3.8 million will expire 2006 to 2014,
and $2.2 million have no expiration date.

NOTE 12 SEGMENT REPORTING AND FOREIGN OPERATIONS

In fiscal 1999, the Company adopted statement of Financial Accounting Standard
("SFAS") 131, "Disclosures about Segments of an Enterprise and Related
Information." Accordingly, the prior year's segment information has been
restated to present the Company's reportable segments, Medical Systems ("MS"),
Radiation Therapy and Planning ("RTP"), Health Care Information Systems
("HCIS"), and Other. The Other segment comprises the Company's physician network
services business that was discontinued in fiscal 1998, see Note 10
"Non-Ordinary Charges and Expenses." The adoption of this statement did not
affect the results of operations or financial position of the Company. The
accounting policies of the Company's operating segments are the same as those
described in Note 1 "Summary of Significant Accounting Policies." The Company is
organized on the basis of products and services. The Company's reportable
segments are strategic business units that offer different products and include
corporate allocations of general and administrative expenses. The following
table summarizes information about the Company's reportable segments for fiscal
1999, 1998 and 1997. Asset information by reportable segment has not been
presented as the Company does not produce and rely on such information.

NOTE 13 COMPREHENSIVE INCOME (LOSS)

    Effective September 28, 1998, the Company adopted SFAS 130, "Reporting
Comprehensive Income" ("FAS 130.") FAS 130 establishes standards for reporting
and displaying income and its components (revenue, expenses, gains and losses)
in a full set of general-purpose financial statements. FAS 130 requires the
classification of items of comprehensive income by their nature in a financial
statement and the accumulated balance of other comprehensive income separately
in the shareholders' equity section of the balance sheet. The Company's
accumulated other comprehensive income consists solely of translation

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

(1) The Company's net income and net income per share in the first quarter
    includes the effects of a non-ordinary pre-tax charge of approximately
    $2.5 million to restructure its European operations.

(2) Gross profit, net loss and net loss per share in the second quarter includes
    the effects of non-ordinary pre-tax charges of approximately $11.2 million
    related to inventory obsolescence. Net loss and net loss per share in the
    second quarter also includes the effects of non-ordinary pre-tax charges of
    approximately $6.0 and $0.8 million related to increased receivable reserves
    and restructuring the Company's South American operations.

(3) In the third quarter, the Company recorded non-ordinary pre-tax charges of
    $7.1 million for additional reserves for South American receivables and
    recourse obligations. The Company also decided to close its AMT refurbishing
    facility in Washington, Missouri and relocate the business to Milpitas
    California. This decision resulted in a non-ordinary pre-tax restructuring
    charge of $0.5 million. The Company also decided to discontinue
    refurbishment of a number of older nuclear medicine equipment lines. This
    decision rendered obsolete substantial inventories of equipment and parts,
    resulting in a non-ordinary pre-tax charges of $2.4 million.

(4) In the fourth quarter the Company purchased UGM. This purchase resulted in a
    pre-tax charge of $1.4 million for the value of acquired in-process research
    and development. The Company took non-ordinary pre-tax charges of
    $1.8 million for additional reserves for South American receivables and
    recourse obligations, $1.2 million for litigation expenses related to the
    pending class action lawsuit and stockholder derivative action. The Company
    also decided to carry out additional restructuring of its South American
    business and took a charge of $0.5 million, partially off-set by a
    $0.2 million recovery of European restructuring charges due to revised
    estimates related to employee severance costs.

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

(1) Gross profit, net loss and net loss per share in the first quarter includes
    the effects of a non-ordinary pre-tax charge of approximately
    $14.5 million. The charge consists of $11.6 million for the discontinuance
    of the Company's LabStat product and $2.9 million for impairment of assets
    utilized in the Company's DSA business. $0.3 million and $0.5 million of
    this charge were reversed in the fourth quarter because the Company lowered
    estimates of liabilities associated with LabStat and because the Company was
    able to redeploy certain of impaired DSA assets elsewhere in its business,
    respectively.

(2) Fourth quarter adjustments include the effect of non-ordinary pre-tax
    charges aggregating approximately $8.2 million. These charges include a
    $4.9 million carrying value adjustment for inventory at the Company's AMT
    facility, a $1.0 million write off of a European distributor receivable, the
    write off of $1.3 million of acquisition costs for non-consummated
    transactions and a charge of $1.9 million related to the discontinuation of
    the MTS business, less $0.9 million in charges taken in the first quarter
    reversed as the amount of the charges was reexamined at the end of the
    fiscal year.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of ADAC Laboratories and Subsidiaries

    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of ADAC
Laboratories and its Subsidiaries (the "Company") at October 3, 1999 and
September 27, 1998, and the results of their operations and their cash flows for
each of the three years in the period ended October 3, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States which 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, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

Our report on the consolidated financial statements of ADAC Laboratories and its
Subsidiaries is included on page 56 of this Form 10-K. In connection with our
audits of such financial statements, we have also audited the related financial
statement schedules listed in the index on page 28 of this Form 10-K. In our

       1.02   OTHER OFFICES.  The board of directors may change the location
of the principal office of the corporation, or establish and maintain
additional offices at such other places as it may from time to time designate.

                                      ARTICLE II

                               MEETINGS OF SHAREHOLDERS

       2.01   PLACE OF MEETINGS.  Meetings of shareholders shall be held at
any place within or outside the State of California designated by the board
of directors.  In the absence of any such designation, shareholders meetings
shall be held at the principal executive office of the corporation.

       2.02   ANNUAL MEETING.  The annual meeting of the shareholders, after
the year of incorporation, shall be held at four o'clock on the third
Wednesday of the first month of the calendar year.  If this day falls on a
legal holiday, the annual meeting shall be held at the same time on the
following business day thereafter.

       2.03   SPECIAL MEETING.  A special meeting of the shareholders may be
called at any time by the board of directors, or by the chairman of the
board, or by the president or by one or more shareholders holding shares in
the aggregate entitled to cast not less than 10% of the votes at that meeting.

              If a special meeting is called by any person or persons other
than the board of directors, the request shall be in writing specifying the
time of such meeting and the general nature

                                        -1-

<PAGE>

of the business proposed to be transacted, and shall be delivered personally
or sent by registered mail or by telegraphic or other facsimile transmission
to the chairman of the board, the president, any vice president or the
secretary of the corporation.  The officer receiving the request shall cause
notice to be promptly given to the shareholders entitled to vote, in
accordance with the provisions of Section 601 of the Corporations Code of the
State of California, that a meeting will be held at the time requested by the
person or persons calling the meeting, not less than thirty-five (35) nor
more than sixty (60) days after the receipt of the request.  If the notice is
not given within twenty (20) days after receipt of the request, the person or
persons requesting the meeting may give the notice.  Nothing contained in
this paragraph of this Section 2.03 shall be construed as limiting, fixing or
affecting the time when a meeting of shareholders called by action of the
board of directors may be held.

       2.04   NOTICE OF SHAREHOLDERS MEETINGS.  All notices of meetings of
shareholders shall be sent or otherwise given in accordance with Section 2.05
of this Article 2 not less than ten (10) nor more than sixty (60) days before
the date of the meeting.  The notice shall specify the place, date and hour
of the meeting and (i) in the case of a special meeting, the general nature
of the business to be transacted, or (ii) in the case of the annual meeting,
those matters which the board of directors, at the time of giving the notice,
intends to present for action by the shareholders.  The notice of any meeting
at which directors are to be elected shall include the name of any nominee or
nominees whom, at the time of the notice, management intends to present for
election.

              If action is proposed to be taken at any meeting for approval
of (i) a contract or transaction in which a director has a direct or indirect
financial interest, pursuant to Section 310 of the Corporations Code of
California, (ii) an amendment of the articles of incorporation, pursuant to
Section 902 of that Code, (iii) a reorganization of the corporation, pursuant
to Section 1201 of that code, (iv) a voluntary dissolution of the
corporation, pursuant to Section 1900 of that Code, or (v) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares, pursuant to Section 2007 of that Code, the notice shall also state
the general nature of that proposal.

       2.05   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE.  Notice of any
meeting of shareholders shall be given either personally or by first class
mail or telegraphic or other written communication, charges prepaid,
addressed to the shareholder at the address of that shareholder appearing on
the books of the corporation or given by the shareholder to the corporation
for the purpose of notice.  If no such address appears on the corporation's
books or is given, notice shall be deemed to have been given if sent to that
shareholder by first class mail or telegraphic or other written communication
to the corporation's principal executive office, or if published at least
once in a newspaper of general circulation in the county where that office is
located.  Notice shall be deemed to have been given at the time when
delivered personally or deposited in the mail or sent by telegram or other
means of written communication.

              If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the

                                        -2-

<PAGE>

shareholder at that address, all future notices or reports shall be deemed to
have been duly given without further mailing if these shall be available to
the shareholder on written demand of the shareholder at the principal
executive office of the corporation for a period of one year from the date of
the giving of the notice.

              An affidavit of the mailing or other means of giving any notice
of any shareholders meeting shall be executed by the secretary, assistant
secretary or any transfer agent of the corporation giving the notice, and
shall be filed and maintained in the minute book of the corporation.

       2.06   QUORUM.  The presence in person or by proxy of the holders of a
majority of the shares entitled to vote at any meeting of shareholders shall
constitute a quorum for the transaction of business.  The shareholders
present at a duly called or held meeting at which a quorum is present may
continue to do business until adjournment, notwithstanding the withdrawal of
enough shareholders to leave less than a quorum, if any action taken (other
than adjournment) is approved by at least a majority of the shares required
to constitute a quorum.

       2.07   ADJOURNED MEETING; NOTICE.  Any shareholders meeting, annual or
special, whether or not a quorum is present, may be adjourned from time to
time by the vote of the majority of the shares represented at that meeting,
either in person or by proxy, but in the absence of a quorum, no other
business may be transacted at that meeting, except as provided in Section
2.06 of this Article 2.

              When any meeting of shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place are announced at a meeting at which the
adjournment is taken, unless a new record date for the adjourned meeting is
fixed, or unless the adjournment is for more than forty-five (45) days from
the date set for the original meeting, in which case the board of directors
shall set a new record date.  Notice of any such adjourned meeting shall be
given to each shareholder of record entitled to vote at the adjourned meeting
in accordance with the provisions of Sections 2.04 and 2.05 of this Article
2.  At any adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting.

       2.08   VOTING.  The shareholders entitled to vote at any meeting of
shareholders shall be determined in accordance with the provisions of Section
701 of the Corporations Code of the State of California, subject to the
provisions of Section 702, Section 703 and Section 704 of the Corporations
Code of the State of California (relating to voting shares held by a
fiduciary, in the name of a corporation, or in joint ownership).  The
shareholders vote may be by voice vote or by ballot; provided, however, that
any election for directors must be by ballot if demanded by any shareholder
before the voting has begun. On any matter other than election of directors,
any shareholder may vote part of the shares in favor of the proposal and
refrain from voting the remaining shares, or vote them against the proposal,
but, if the shareholder fails to specify the number of shares which the
shareholder is voting affirmatively, it will be conclusively presumed that
the shareholders approving vote is with respect to all shares that the
shareholder is entitled to vote.  If a quorum is present, the affirmative
vote of the majority of the shares represented at the meeting and entitled to
vote on any

                                        -3-
<PAGE>

matter (other than the election of directors) shall be the act of the
shareholders, unless the vote of a greater number or voting by classes is
required by California General Corporation Law or by the articles of
incorporation.

              At a shareholders meeting at which directors are to be elected,
no shareholder shall be entitled to cumulate votes (i.e., cast for any one or
more candidates a number of votes greater than the number of the shareholders
shares) unless the candidates names have been placed in nomination prior to
commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholders intention to cumulate votes.
If any shareholder has given such a notice, then every shareholder entitled
to vote may cumulate votes for candidates in nomination and give one
candidate a number of votes equal to the number of directors to be elected,
multiplied by the number of votes to which that shareholder's shares are
entitled, or distribute the shareholder's votes on the same principle among
any or all of the candidates as the shareholder thinks fit.  The candidates
receiving the highest number of votes, up to the number of directors to be
elected, shall be elected.

       2.09   WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS.  The
transactions of any meeting of shareholders, either annual or special,
however called and noticed and wherever held, shall be as valid as though had
at a meeting duly held after regular call and notice, if a quorum be present
either in person or by proxy, and if, either before or after the meeting,
each person entitled to vote who was not present in person or by proxy signs
a written waiver of notice or a consent to a holding of the meeting, or an
approval of the minutes.  The waiver of notice or consent need not specify
either the business to be transacted or the purpose of any annual or special
meeting of shareholders, except that if action is taken or proposed to be
taken for approval for any of those matters specified in Section 601 of the
Corporations Code of the State of California; the waiver of notice or consent
shall state the general nature of the proposal.  All such waivers, consents
or approvals shall be filed with the corporate records or made a part of the
minutes of the meeting.

              Attendance by a person at a meeting shall also constitute a
waiver of notice of that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the
meeting is not lawfully called or convened, and except that attendance at a
meeting is not a waiver of any right to object to the consideration of
matters not included in the notice of the meeting if that objection is
expressly made at the meeting.

       2.10   SHAREHOLDERS ACTION BY WRITTEN CONSENT WITHOUT A MEETING.  Any
action which may be taken at any annual or special meeting of shareholders
may be taken without a meeting and without prior notice if a consent in
writing setting forth the action so taken is signed by the holders of
outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take that action at a meeting at which all
shares entitled to vote on that action were present and voted.  In the case
of election of directors, such a consent shall be effective only if signed by
the holders of all outstanding shares entitled to vote for the election of
directors; provided, however, that a director may be elected at any time to
fill a vacancy on the board of directors that has not been filled by the
directors by the written consent of the holders of a majority of the
outstanding

                                        -4-

<PAGE>

shares entitled to vote for the election of directors.  All such consents
shall be filed with the secretary of the corporation and shall be maintained
in the corporate records. Any shareholder giving a written consent, or the
shareholder's proxy holders, or a transferee of the shares or a personal
representative of the shareholder of their respective proxy holders, may
revoke the consent by a writing received by the secretary of the corporation
before written consents of the number of shares required to authorize the
proposed action have been filed with the secretary.

              If the consents of all shareholders entitled to vote have not
been solicited in writing, and if the unanimous written consent of all such
shareholders shall not have been received, the secretary shall give prompt
notice of the corporate action approved by the shareholders without a
meeting. This notice shall be given in the manner specified in Section 2.05
of this Article 2.  In the case of approval of (i) contracts or transactions
in which a director has a direct or indirect financial interest, pursuant to
Section 310 of the Corporations Code of California, (ii) indemnification of
agents of the corporation, pursuant to Section 317 of that Code, (iii) a
reorganization of the corporation, pursuant to Section 1201 of that Code, and
(iv) a distribution in dissolution other than in accordance with the rights
of outstanding preferred shares, pursuant to Section 2007 of that Code, the
notice shall be given at least ten (10) days before the consummation of any
action authorized by that approval.

       2.11   RECORD DATE FOR SHAREHOLDER NOTICE, VOTING AND GIVING CONSENTS.
For purposes of determining the shareholders entitled to notice of any
meeting or to vote or entitled to give consent to corporate action without a
meeting, the board of directors may fix, in advance, a record date, which
shall not be more than sixty (60) days before any such action without a
meeting, and in this event only shareholders of record on the date so fixed
are entitled to notice and to vote or to give consents, as the case may be,
notwithstanding any transfer of any shares on the books of the corporation
after the record date except as otherwise provided in the California General
Corporation Law.

              If the board of directors does not so fix a record date:

              (a)    The record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given
or, if notice is waived, at the close of business on the business day next
preceding the day on which the meeting is held.

              (b)    The record date for determining shareholders entitled to
give consent to corporate action in writing without a meeting, (i) when no
prior action by the board has been taken, shall be the day on which the first
written consent is given, or (ii) when prior action of the board has been
taken, shall be at the close of business on the day on which the board adopts
the resolution relating to that action, or the sixtieth (60th) day before the
date of such other action, whichever is later.

                                        -5-

<PAGE>

       2.12   PROXIES.  Every person entitled to vote for directors or on any
other matter shall have the right to do so either in person or by one or more
agents authorized by a written proxy signed by the person and filed with the
secretary of the corporation.  A proxy shall be deemed signed if the
shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the shareholder or the
shareholder's attorney in fact.  A validly executed proxy which does not
state that it is irrevocable shall continue in full force and effect unless
(i) revoked by the person executing it, before the vote pursuant to that
proxy, by a writing delivered to the corporation stating that the proxy is
revoked, or by a subsequent proxy executed by, or attendance at the meeting
and voting in person by, the person executing the proxy; or (ii) written
notice of the death or incapacity of the maker of that proxy is received by
the corporation before the vote pursuant to that proxy is counted; provided,
however, that no proxy shall be valid after the expiration of eleven (11)
months from the date of the proxy, unless otherwise provided in the proxy.

       2.13   INSPECTORS OF ELECTION.  Before any meeting of shareholders,
the board of directors may appoint any persons other than nominees for office
to act as inspectors of election at the meeting or its adjournment.  If no
inspectors of election are so appointed, the chairman of the meeting may, and
on the request of any shareholder or a shareholder's proxy shall, appoint
inspectors of election at the meeting.  The number of inspectors shall be
either one (1) or three (3).  If inspectors are appointed at a meeting on the
request of one or more shareholders or proxies present at the meeting shall
determine whether one (1) or three (3) inspectors are to be appointed.  If
any person appointed as inspector fails to appear or fails or refuses to act,
the chairman of the meeting may, and upon the request of any shareholder or a
shareholder's proxy shall, appoint a person to fill the vacancy.

              These inspectors shall:

              (a)    Determine the number of shares outstanding and the
voting power of each, the shares represented at the meeting, the existence of
a quorum, and the authenticity, validity, and effect of proxies;

              (b)    Receive votes, ballots, or consents;

              (c)    Hear and determine all challenges and questions in any
way arising in connection with the right to vote;

              (d)    Count and tabulate all votes or consents;

              (e)    Determine when the polls shall close;

              (f)    Determine the results; and

              (g)    Do any other acts that may be proper to conduct the
election or vote with fairness to all shareholders.

                                     ARTICLE III

                                      DIRECTORS

       3.01   POWERS.  Subject to the provisions of the California General
Corporation Law and any limitations in the articles of incorporation and
these bylaws relating to action required to be approved by the shareholders
or by the outstanding shares, the business and affairs of the corporation
shall be managed and all corporate powers shall be exercised by or under the
direction of the board of directors.  Notwithstanding the foregoing, until
November 30, 1980, the issuance of shares or the granting of options to
purchase shares of this corporation's common stock to officers and directors
of this corporation, shall require the unanimous approval by all members of
the board of directors.

       3.02   NUMBER AND QUALIFICATION OF DIRECTORS.  The number of directors
shall be not less than five (5) or more than eight (8), the exact number of
directors shall be fixed from time to time by a resolution duly adopted by
the vote or written consent of holders of a majority of the outstanding
shares entitled to vote; provided, however, that an amendment reducing the
number of directors to a number less than five (5) cannot be adopted if the
votes cast against its adoption at a meeting, or the shares not consenting in
the case of action by written consent, are equal to more than 16 2/3% of the
outstanding shares entitled to vote.

       3.03   ELECTION AND TERM OF OFFICE OF DIRECTORS.  Directors shall be
elected at each annual meeting of the shareholders to hold office until the
next annual meeting.  Each director, including a director elected to fill a
vacancy, shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.

       3.04   VACANCIES.  Vacancies in the board of directors may be filled
by a majority of the remaining directors, though less than a quorum, or by a
sole remaining director, except that a vacancy created by the removal of a
director by the vote or written consent of the shareholders, or by court
order, may be filled only by the vote of a majority of the shares entitled to
vote represented at a duly held meeting at which a quorum is present, or by
the shares entitled to vote.  Each director so elected shall hold office
until the next annual meeting of the shareholders and until a successor has
been elected and qualified.

              A vacancy or vacancies in the board of directors shall be
deemed to exist in the event of the death, resignation or removal of any
director, or if the board of directors who has been declared of unsound mind

              The shareholders may elect a director or directors at any time

outstanding shares entitled to vote.

              Any director may resign effective on giving written notice to
the chairman of the board, the president, the secretary or the board of
directors, unless the notice specifies a later time for that resignation to
become effective.  If the resignation of a director is effective at a future
time, the board of directors may elect a successor to take office when the
resignation becomes effective.

              No reduction of the authorized number of directors shall have
the effect of removing any director before that director's term of office

each annual meeting of shareholders, the board of directors shall hold a

constitute a quorum for the transaction of business, except to adjourn as
provided in Section 3.11 of this Article 3.  Every act or decision done or

California (as to approval of contracts or transactions in which a director
has a direct or indirect material financial interest), Section 311 of that
Code (as to appointment of committees) and Section 317(e) of that Code (as to

meeting at which a quorum is initially present may continue to transact
business notwithstanding the withdrawal of directors if any action taken is
approved by at least a majority of the required quorum for that meeting.

       3.10   WAIVER OF NOTICE.  The transactions of any meeting of the board
of directors, however called and noticed or wherever held, shall be as valid
as though had at a meeting duly held after regular call and notice if a
quorum is present, and if either before or after the meeting, each of the
directors not present signs a written waiver of notice, a consent to holding
the meeting or an approval of the minutes.  The waiver of notice or consent
need not specify the purpose of the meeting.  All such waivers, consents and
approvals shall be filed with the corporate records or made a part of the
minutes of the meeting.  Notice of a meeting shall also be deemed given to
any director who attends the meeting without protesting before or at its
commencement the lack of notice to that director.

not constituting a quorum, may adjourn any meeting to another time and place.

taken by the board of directors may be taken without a meeting if all members
of the board shall individually or collectively consent in writing to that

consents shall be filed with the minutes of the proceedings of the board.

       3.14   FEES AND COMPENSATION OF DIRECTORS.  Directors and members of
committees may receive such compensation, if any, for their services and such
reimbursement of expenses as may be fixed or determined by resolution of the
board of directors.  This Section 3.11 shall not be construed to preclude any
director from serving the corporation in any other capacity as an officer,
agent, employee or otherwise and receiving compensation for those services.

                         OFFICERS, EMPLOYEES AND OTHER AGENTS

       6.01   AGENTS, PROCEEDINGS AND EXPENSES.  For the purposes of this
Article, "agent" means any person who is or was a director, officer, employee
or other agent of this corporation, or is or was serving at the request of
this corporation as a director, officer, employee or agent of another foreign
or domestic corporation, partnership, joint venture, trust or other
enterprise, or was a director, officer, employee or agent of a foreign or
domestic corporation which was a predecessor corporation of this corporation
or of another enterprise at the request of such predecessor corporation;
"proceeding" means any threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative; and "expenses"
includes, without limitation, attorneys' fees and any expenses of
establishing a right to indemnification under Section 6.04 or Section 6.05(c)
of this Article.

       6.02   ACTIONS OTHER THAN BY THE CORPORATION.  This corporation shall
indemnify any person who was or is a party, or is threatened to be made a
party, to any proceeding (other than an action by or in the right of this
corporation to procure a judgment in its favor) by reason of the fact that
such person is or was an agent of this corporation, against expenses,
judgments, fines, settlements and other amounts actually and reasonably
incurred in connection with such proceedings if that person

                                        -12-
<PAGE>

acted in good faith and in a manner that person reasonably believed to be in
the best interests of this corporation and, in the case of a criminal
proceeding, had no reasonable cause to believe the conduct of that person was
unlawful, conviction or upon a plea of nolo contendere or its equivalent
shall not, of itself, create a presumption that the person did not act in
good faith and in a manner which the person reasonably believed to be in the
best interests of this corporation or that the person has reasonable cause to
believe that the person's conduct was unlawful.

       6.03   ACTIONS BY THE CORPORATION.  This corporation shall indemnify
any person who was or is a party, or is threatened to be made a party, to any
threatened, pending or completed action by or in the right of this
corporation to procure a judgment in its favor by reason of the fact that
person is or was an agent of this corporation, against expenses actual and
reasonably incurred by that person in connection with the defense or
settlement of that action if that person acted in good faith, in a manner
that person believed to be in the best interest of this corporation and with
such care, including reasonable inquiry, as an ordinarily prudent person in a
like position would use under similar circumstances.  No indemnification
shall be made under this Section 6.03.

              (a)    In respect of any claim, issue or matter as to which
that person shall have been adjudged to be liable to this corporation in the
performance of that person's duty to this corporation, unless and only to the
extent that the court in which that proceeding is or was pending shall
determine upon application that, in view of the circumstances of the case,
that person is fairly and reasonably entitled to indemnity for the expenses
which the court shall determine;

              (b)    Of amounts paid in settling or otherwise disposing of a
threatened or pending action, with or without court approval; or

              (c)    Of expenses incurred in depending a threatened or
pending action which is settled or otherwise disposed of without court
approval.

       6.04   SUCCESSFUL DEFENSE BY AGENT.  To the extent that an agent of
this corporation has been successful on the merits in defense of any
proceeding referred to in Sections 6.02 or 6.03 of this Article, or in
defense of any claim, issue or matter therein, the agent shall be indemnified
against expenses actually and reasonably incurred by the agent in connection
therewith.

       6.05   REQUIRED APPROVAL.  Except as provided in Section 6.04 of this
Article, any indemnification under this Article shall be made by this
corporation only if authorized in the specific case on a determination that
indemnification of the agent is proper in the circumstances because the agent
has met the applicable standard of conduct set forth in Sections 6.02 or 6.03
of this Article, by:

              (a)    A majority vote of a quorum consisting of directors who
are not parties to the proceeding;

              (b)    Approval by the affirmative vote of a majority of the
shares of this corporation entitled to vote represented at a duly held
meeting at which a quorum is present or by the written

                                        -13-

<PAGE>

consent of holders of a majority of the outstanding shares entitled to vote.
For this purpose, the shares owned by the person to be indemnified shall not
be considered outstanding or entitled to vote thereon; or

              (c)    The court in which the proceeding is or was pending, on
application made by this corporation or the agent or the attorney or other
person rendering services in connection with the defense, whether or not such
application by the agent, attorney or other person is opposed by this
corporation.

       6.06   ADVANCE OF EXPENSES.  Expenses incurred in defending any
proceeding may be advanced by this corporation before the final disposition
of the proceeding on receipt of an undertaking by or on behalf of the agent
to repay the amount of the advance unless it shall be determined ultimately
that the agent is entitled to be indemnified as authorized in this Article.

       6.07   OTHER CONTRACTUAL RIGHTS.  Nothing contained in this Article
shall affect any right to indemnification to which persons other than
directors and officers of this corporation or any subsidiary hereof may be
entitled by contract or otherwise.

       6.08   LIMITATIONS.  No indemnification or advance shall be made under
this Article, except as provided in Section 6.04 or Section 6.05(c), in any
circumstance where it appears:

              (a)    That it would be inconsistent with a provision of the
articles, a resolution of the shareholders or an agreement in effect at the
time of the accrual of the alleged cause of action asserted in the proceeding
in which the expenses were incurred or other amounts were paid, which
prohibits or otherwise limits indemnification; or

              (b)    That it would be inconsistent with any condition
expressly imposed by a court in approving a settlement.

       6.09   INSURANCE.  Upon and in the event of a determination by the
board of directors of this corporation to purchase such insurance on behalf
of any agent of the corporation against any liability asserted against or
incurred by the agent in such capacity or arising out of the agent's status
as such whether or not this corporation would have the power to indemnify the
agent against that liability under the provisions of this section.

       6.10   FIDUCIARIES OF CORPORATE EMPLOYEE BENEFIT PLAN.  This Article
does not apply to any proceeding against any trustee, investment manager or
other fiduciary of an employee benefit plan in that person's capacity as
such, even though that person may also be an agent of the corporation  as
defined in Section 6.01 of this article.  Nothing contained in this Article
shall limit any right to indemnification to which such a trustee, investment
manager or other fiduciary may be entitled by contract or otherwise, which
shall be enforceable to the extent permitted by 2.07 of the California
Corporations Code.

is not in the State of California, at its principal business office in this

corporation of the corporation.

       7.04   INSPECTION BY DIRECTORS.  Every director shall have the

periodic reports as they consider appropriate.

and any income statement of the corporation for each quarterly period of each
fiscal year, and any accompanying balance sheet of the corporation as of the
end of each such period, that has been prepared by the corporation shall be

(12) months and each such statement shall be exhibited at all reasonable
times to any shareholder demanding an examination of any such statement or a
copy shall be mailed to any such shareholder.

the outstanding shares of any class of stock of the corporation makes a
written request to the corporation for an income statement of the corporation
for the three month, six month or nine month period of the then current
fiscal year ended more than thirty (30) days before the date of the request,
and a balance sheet of the corporation as of the end of that period, the
chief financial officer shall cause that statement to be prepared, if not

statements to the person making the request within thirty (30) days after the
receipt of the request.  If the corporation has not sent to the shareholders
its annual report for the last fiscal year, this report shall likewise be

days after the request.

       The corporation shall also, on the written request of any shareholder,
mail to the shareholder a copy of the last annual, semi-annual or quarterly
income statement which it has prepared and a balance sheet as of the end of
that period.

       The quarterly income statements and balance sheets referred to in this

accountants engaged by the corporation or the certificate of an authorized
officer of the corporation that the financial statements were prepared
without audit from the books and records of the corporation.

purposes of determining the shareholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful action (other than action
by shareholders by written consent without a meeting), the board of directors
may fix, in advance, a record date, which shall not be more than sixty (60)
days before any such action, and in that case only shareholders of record on
the date so fixed are entitled to receive the dividend rights, as the case
may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date so fixed, except as otherwise provided in
the California General Corporation Law.

       If the board of directors does not so fix a record date, the record

of directors, except as otherwise provided in these bylaws, may authorize any
officer or officers, agent or agents, to enter into any contract or execute
any instrument in the name of and on behalf of the corporation, and this
authority may be general or confined to specific instances; and, unless so
authorized or ratified by the board of directors or within the agency power
of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge
its credit or to render it liable for any purpose or for any amount.

       8.04   CERTIFICATES FOR SHARES.  A certificate or certificates for
shares of the capital stock of the corporation shall be issued to each
shareholder when any of these shares are fully paid, and the board of
directors may authorize the issuance of certificates or shares as partly paid
provided that these certificates shall state the amount of the consideration
to be paid for them and the amount paid. All certificates shall be signed in
the name of the corporation by the chairman of the board or vice chairman of
the board or the president or vice president and by the chief financial
officer or an assistant treasurer or the secretary or any assistant
secretary, certifying the number of shares and the class or series of shares
owned by the shareholder.  Any or all of the signatures on the certificate
may be facsimile.  In case any officer, transfer agent or registrar who has
signed or whose facsimile signature has been placed on a certificate shall
have ceased to be that officer, transfer agent or registrar before that
certificate is issued, it may be issued by the corporation with the same
effect as if that person were an officer, transfer agent or registrar at the
date of issue.

new certificates for shares shall be issued to replace an old certificate
unless the latter is surrendered to the corporation and canceled at the same
time.  The board of directors may, in case any share certificate or
certificate for any other security is lost, stolen or destroyed, authorize
the issuance of a replacement certificate on such terms and conditions as the
board may require, including provision for indemnification of the corporation
secured by a bond or other adequate security sufficient to protect the
corporation against any claim that may be made against it, including any
expense or liability, on account of the alleged loss, theft or destruction of
the certificate or the issuance of the replacement certificate.

       8.06   REPRESENTATION OF SHARES OF OTHER CORPORATIONS.  The chairman
of the board, the president or any vice president or any other person
authorized by resolution of the board of directors or by any of the foregoing
designated officers, is authorized to vote on behalf of the corporation any
and all shares of any other corporation or corporations, foreign or domestic,
standing in the name of the corporation.  The authority granted to these
officers to vote or represent on behalf of the corporation any and all shares
held by the corporation in any other corporation or corporations may be
exercised by any of these officers in person or by any person authorized to
do so by a proxy duly executed by these officers.

       8.07   CONSTRUCTION AND DEFINITIONS.  Unless the context requires
otherwise, the general provisions, rules of construction and definitions in
the California General Corporation Law shall govern the construction of these
bylaws.  Without limiting the generality of this provision, the singular
number includes the plural, the plural number includes the singular and the

         this Agreement (including the amount limitations set forth in PARAGRAPH
         2.02 and the conditions set forth in SECTION III), each Lender
         severally agrees to advance to Borrower from time to time during the
         period beginning on the Closing Date and ending on the Maturity Date
         such loans as Borrower may request under this PARAGRAPH 2.01
         (individually, a "LOAN"); PROVIDED, HOWEVER, that (i) the aggregate
         principal amount of all Loans made by such Lender at any time
         outstanding shall not exceed such Lender's Commitment at such time and
         (ii) the aggregate principal amount of all Loans made by all Lenders at
         any time outstanding shall not exceed the Total Commitment at such
         time. All Loans shall be made on a pro rata basis by the Lenders in
         accordance with their respective Proportionate Shares, with each
         Borrowing to be comprised of a Loan by each Lender equal to such
         Lender's Proportionate Share of such Borrowing. Except as otherwise
         provided herein, Borrower may borrow, repay and reborrow Loans until
         the Maturity Date.

                  (b) NOTICE OF BORROWING. Borrower shall request each Borrowing
         by delivering to Agent an irrevocable written notice in the form of
         EXHIBIT A, appropriately completed (a "NOTICE OF BORROWING"), which
         specifies, among other things:

                           (i) The principal amount of the requested Borrowing,
                  which shall be in the amount of (A) $100,000 or an integral
                  multiple of $50,000 in excess thereof in the case of a
                  Borrowing consisting of Base Rate Loans; or (B) $400,000 or an
                  integral multiple of $100,000 in excess thereof in the case of
                  a Borrowing consisting of LIBOR Loans;

                           (ii) Whether the requested Borrowing is to consist of
                  Base Rate Loans or LIBOR Loans;

                           (iii) If the requested Borrowing is to consist of
                  LIBOR Loans, the initial Interest Period selected by Borrower

                           (iv) The date of the requested Borrowing, which shall
                  be a Business Day;

         Borrower shall give each Notice of Borrowing to Agent at least three
         (3) Business Days before the date of the requested Borrowing in the
         case of a Borrowing consisting of LIBOR Loans with Interest Periods of
         one month or longer and on or before the date of the requested
         Borrowing in the case of any other Borrowing. Each Notice of Borrowing
         shall be delivered by first-class mail or facsimile to Agent at the
         office or facsimile number and during the hours specified in PARAGRAPH
         8.01; PROVIDED, HOWEVER, that Borrower shall promptly deliver to Agent
         the original of any Notice of Borrowing initially delivered by
         facsimile. Agent shall promptly notify each Lender of the contents of
         each Notice of Borrowing and of the amount and Type of (and, if
         applicable, the Interest Period for) each Loan to be made by such
         Lender as part of the requested Borrowing.

<PAGE>

                  (c) LOAN INTEREST RATES. Borrower shall pay interest on the
         unpaid principal amount of each Loan from the date of such Loan until
         the maturity thereof, at one of the following rates per annum:

                           (i) During such periods as such Loan is a Base Rate
                  Loan, at a rate per annum equal to the Base Rate PLUS the
                  Applicable Margin therefor, such rate to change from time to
                  time as the Applicable Margin or Base Rate shall change; and

                           (ii) During such periods as such Loan is a LIBOR
                  Loan, at a rate per annum equal at all times during each
                  Interest Period for such LIBOR Loan to the LIBO Rate for such
                  Interest Period PLUS the Applicable Margin therefor, such rate
                  to change from time to time during such Interest Period as the
                  Applicable Margin shall change.

         All Loans in each Borrowing shall, at any given time prior to maturity,
         bear interest at one, and only one, of the above rates. The number of
         Borrowings consisting of LIBOR Loans shall not exceed seven (7) at any
         time.
                  (d) CONVERSION OF LOANS. Borrower may convert any Borrowing
         from one Type of Borrowing to the other Type; PROVIDED, HOWEVER, that
         any conversion of a Borrowing consisting of LIBOR Loans into a
         Borrowing consisting of Base Rate Loans shall be made on, and only on,
         the last day of an Interest Period for such LIBOR Loans. Borrower shall
         request such a conversion by an irrevocable written notice to Agent in
         the form of EXHIBIT B, appropriately completed (a "NOTICE OF
         CONVERSION"), which specifies, among other things:

                           (i)      The Borrowing which is to be converted;

                           (ii) The Type of Borrowing into which such Borrowing
                  is to be converted;

                           (iii) If such Borrowing is to be converted into a
                  Borrowing consisting of LIBOR Loans, the initial Interest
                  Period selected by Borrower for such Loans in accordance with
                  SUBPARAGRAPH 2.01(e); and

                           (iv) The date of the requested conversion, which
                  shall be a Business Day.

         Borrower shall give each Notice of Conversion to Agent at least three
         (3) Business Days before the date of the requested conversion in the
         case of a conversion into a Borrowing consisting of LIBOR Loans with
         Interest Periods of one month or more and on or before the date of the
         requested conversion in the case of a conversion into any other
         Borrowing. Each Notice of Conversion shall be delivered by first-class
         mail or facsimile to Agent at the office or to the facsimile number and
         during the hours specified in PARAGRAPH 8.01; PROVIDED, HOWEVER, that

                  two (2) weeks, one (1) month, two (2) months, three (3) months
                  or six (6) months; PROVIDED, HOWEVER, that (A) any Interest
                  Period which would otherwise end on a day which is not a
                  Business Day shall be extended to the next succeeding Business
                  Day unless such next Business Day falls in another calendar
                  month, in which case such Interest Period shall end on the
                  immediately preceding Business Day; (B) any Interest Period
                  (other than a one-week or two-week Interest Period) which
                  begins on the last Business Day of a calendar month (or on a
                  day for which there is no numerically corresponding day in the
                  calendar month at the end of such Interest Period) shall end
                  on the last Business Day of a calendar month; and (C) no such
                  Interest Period shall end after the Maturity Date.

                           (ii) Borrower shall notify Agent by an irrevocable
                  written notice in the form of EXHIBIT C, appropriately
                  completed (a "NOTICE OF INTEREST PERIOD SELECTION"), at least
                  three (3) Business Days prior to the last day of each Interest
                  Period for LIBOR Loans of the Interest Period selected by
                  Borrower for the next succeeding Interest Period for such
                  Loans. Each Notice of Interest Period Selection shall be given
                  by first-class mail or facsimile to the office or the
                  facsimile number and during the hours specified in PARAGRAPH
                  8.01; PROVIDED, HOWEVER, that Borrower shall promptly deliver
                  to Agent the original of any Notice of Interest Period
                  Selection initially delivered by facsimile. If Borrower fails
                  to notify Agent of the next Interest Period for LIBOR Loans in
                  accordance with this SUBPARAGRAPH 2.01(e), such Loans shall
                  automatically convert to Base Rate Loans on the last day of
                  the current Interest Period therefor.

                  (f) SCHEDULED LOAN PAYMENTS. Borrower shall repay the
         principal amount of the Loans on the Maturity Date. Borrower shall pay
         accrued interest on the unpaid principal amount of each Loan in arrears
         (A) in the case of a Base Rate Loan, on the last day in each March,
         June, September and December, (B) in the case of a LIBOR Loan, on the
         last day of each Interest Period therefor (and, if any such Interest
         Period is longer than three (3) months, every three (3) months); and
         (C) in the case of all Loans, upon prepayment (to the extent thereof)
         and at maturity.

                  (g) PURPOSE. Borrower shall use the proceeds of the Loans (i)
         first, to repay on the Closing Date all indebtedness outstanding under
         the Existing Credit Agreement and (ii) thereafter, for Borrower's
         general corporate needs, including the consummation of acquisitions
         otherwise permitted pursuant to the terms of this Agreement.

                  (h) MATURITY DATE EXTENSIONS. On or before the last Business
         Day of each December beginning on December 31, 2001, Borrower may
         request the Lenders to extend the Maturity Date for an additional
         one-year period. Borrower shall request each such extension by
         appropriately completing, executing and delivering to Agent a written

<PAGE>

         request in the form of EXHIBIT D (a " MATURITY DATE EXTENSION
         REQUEST"). Borrower understands that this SUBPARAGRAPH 2.01(h) is
         included in this Agreement for Borrower's convenience in requesting
         extensions and acknowledges that neither Agent nor any Lender has
         promised (either expressly or by implication), and neither Agent nor
         any Lender has any obligation or commitment, to extend the Maturity
         Date at any time. Agent shall promptly deliver to each Lender three (3)
         copies of each Maturity Date Extension Request received by Agent. If a
         Lender, in its sole and absolute discretion, consents to any Maturity
         Date Extension Request, such Lender shall evidence such consent by
         executing and returning two (2) copies of the Maturity Date Extension
         Request to Agent not later than the last Business Day which is thirty
         (30) days after the date Borrower delivered to Agent the Maturity Date
         Extension Request. Any failure by any Lender to execute and return a
         Maturity Date Extension Request shall be deemed a denial thereof. If
         Borrower shall deliver a Maturity Date Extension Request to Agent
         pursuant to the first sentence of this SUBPARAGRAPH 2.01(h), then not
         later than the last Business Day which is thirty-five (35) days after
         the date Borrower delivered to Agent the Maturity Date Extension
         Request, Agent shall notify Borrower in writing whether (i) Agent has
         received a copy of the Maturity Date Extension Request executed by each
         Lender, in which case the definition of " Maturity Date" set forth in
         PARAGRAPH 1.01 shall be deemed amended as provided in the Maturity Date
         Extension Request as of the date of such written notice from Agent to
         Borrower, or (ii) Agent has not received a copy of the Maturity Date
         Extension Request executed by each Lender, in which case such Maturity
         Date Extension Request shall be deemed denied. Agent shall deliver to
         Borrower, with each written notice under CLAUSE (i) of the preceding
         sentence which notifies Borrower that Agent has received a Maturity
         Date Extension Request executed by each Lender, a copy of the Maturity
         Date Extension Request so executed by each Lender.

         2.2.    COMMITMENT REDUCTIONS, ETC.

                  (a) OPTIONAL REDUCTION OR CANCELLATION OF COMMITMENTS.
         Borrower may, upon three (3) Business Days written notice to Agent,
         permanently reduce the Total Commitment by the amount of one million
         Dollars ($1,000,000) or an integral multiple of one million Dollars
         ($1,000,000) in excess thereof or cancel the Total Commitment in its
         entirety; PROVIDED, HOWEVER, that:

                           (i) Borrower may not reduce the Total Commitment
                  prior to the Maturity Date, if, after giving effect to such
                  reduction, the aggregate principal amount of all Loans then
                  outstanding would exceed the Total Commitment; and

                           (ii) Borrower may not cancel the Total Commitment
                  prior to the Maturity Date, if, after giving effect to such
                  cancellation, any Loans would then remain outstanding.

                  (b) MANDATORY REDUCTION OR CANCELLATION OF COMMITMENTS. If, at
         any time, Borrower is required to make any mandatory prepayment of
         Loans pursuant to CLAUSE (ii) OF SUBPARAGRAPH 2.04(c), the Total
         Commitment shall be automatically and permanently

<PAGE>

         reduced or cancelled by an amount equal to the full amount of any
         required prepayment.

                  (c) EFFECT OF COMMITMENT REDUCTIONS. From the effective date
         of any reduction of the Total Commitment, the Commitment Fees payable
         pursuant to SUBPARAGRAPH 2.03(b) shall be computed on the basis of the
         Total Commitment as so reduced. Once reduced or cancelled, the Total
         Commitment may not be increased or reinstated without the prior written
         consent of all Lenders. Any reduction of the Total Commitment pursuant
         to SUBPARAGRAPH 2.02(a) or SUBPARAGRAPH 2.02(b) shall be applied
         ratably to reduce each Lender's Commitment in accordance with CLAUSE
         (i) OF SUBPARAGRAPH 2.08(a).

         2.3.    FEES.

                  (a) AGENT'S FEE. Borrower shall pay to Agent, for its own
         account, agent's fees and other compensation in the amounts and at the
         times set forth in the Agent's Fee Letter.

                  (b) COMMITMENT FEES. Borrower shall pay to Agent, for the
         ratable benefit of the Lenders as provided in CLAUSE (iii) OF
         SUBPARAGRAPH 2.08(a), nonrefundable commitment fees (the "COMMITMENT
         FEES") equal to the Commitment Fee Percentage on the daily average
         Unused Commitment for the period beginning on the date of this
         Agreement and ending on the Maturity Date. The Commitment Fee
         Percentage shall be determined as provided in the Pricing Grid and may
         change for each calendar quarter. Borrower shall pay the Commitment
         Fees in arrears on the last day in each March, June, September and
         December and on the Maturity Date (or if the Total Commitment is
         cancelled on a date prior to the Maturity Date, on such prior date).

                  (c) PARTICIPATION FEE. On the Closing Date, Borrower shall pay
         to Agent, for the benefit of the Lenders, a one-time non-refundable
         participation fee equal to 0.15% of the Total Commitment to be shared
         among the Lenders pro rata in accordance with such Lenders' respective
         proportionate share of the Total Commitment.

         2.4.    PREPAYMENTS.

                  (a) TERMS OF ALL PREPAYMENTS. Upon the prepayment of any Loan
         (whether such prepayment is an optional prepayment under SUBPARAGRAPH
         2.04(b), a mandatory prepayment required by SUBPARAGRAPH 2.04(c) or a
         mandatory prepayment required by any other provision of this Agreement
         or the other Credit Documents, including, without limitation, a
         prepayment upon acceleration), Borrower shall pay to the Lender which
         made such Loan (i) all accrued interest to the date of such prepayment
         on the amount prepaid and (ii) if such prepayment is the prepayment of
         a LIBOR Loan on a day other than the last day of an Interest Period for
         such LIBOR Loan, all amounts payable to such Lender pursuant to
         PARAGRAPH 2.11.

                  (b) OPTIONAL PREPAYMENTS. At its option, Borrower may, upon
         three (3) Business Days notice to Agent, prepay the Loans in any
         Borrowing in part, in an aggregate principal amount of $1,000,000 or
         more, or in whole; except that Borrower may prepay the Loans in any
         Borrowing consisting of Base Rate Loans on the last Business Day in

<PAGE>

         any fiscal quarter of Borrower upon same day notice to Agent if
         Borrower delivers such notice to Agent not later than 1:00 p.m. on
         the date of such prepayment.

                  (c) MANDATORY PREPAYMENTS. Borrower shall immediately repay
         Loans as follows:

                           (i) If, at any time, the aggregate principal amount
                  of all Loans then outstanding exceeds the Total Commitment at
                  such time, Borrower shall immediately prepay Loans in an
                  aggregate principal amount equal to such excess; and

                           (ii) Upon the incurrence by Borrower of unsecured
                  Indebtedness of the type permitted pursuant to CLAUSE (xi) OF
                  SUBPARAGRAPH 5.02(a), Borrower shall immediately prepay Loans
                  in an amount equal to the Net Proceeds derived from the
                  Indebtedness so incurred.

         2.5.    OTHER PAYMENT TERMS.

                  (a) PLACE AND MANNER. Borrower shall make all payments due to
         each Lender or Agent hereunder by payments to Agent at Agent's office
         located at the address specified in PARAGRAPH 8.01, with each payment
         due to a Lender to be for the account of such Lender and such Lender's
         Applicable Lending Office. Borrower shall make all payments hereunder
         in lawful money of the United States and in same day or immediately
         available funds not later than 12:00 noon on the date due, except that
         Borrower may make prepayments of the Loans in a Borrowing consisting of
         Base Rate Loans on the last Business Day of a fiscal quarter as late as
         1:00 p.m. Agent shall promptly disburse to each Lender each payment
         received by Agent for the account of such Lender.

                  (b) DATE. Whenever any payment due hereunder shall fall due on
         a day other than a Business Day, such payment shall be made on the next
         succeeding Business Day, and such extension of time shall be included
         in the computation of interest or fees, as the case may be.

                  (c) LATE PAYMENTS. If any amounts required to be paid by
         Borrower under this Agreement or the other Credit Documents (including,
         without limitation, principal or interest payable on any Loan, any fees
         or other amounts) remain unpaid after such amounts are due, Borrower
         shall pay interest on the aggregate, outstanding balance of such
         amounts from the date due until those amounts are paid in full at a per
         annum rate equal to the Base Rate PLUS two percent (2.00%), such rate
         to change from time to time as the Base Rate shall change.

                  (d) APPLICATION OF PAYMENTS. All payments hereunder shall be
         applied first to unpaid fees, costs and expenses then due and payable
         under this Agreement or the other Credit Documents, second to accrued
         interest then due and payable under this Agreement or the other Credit
         Documents and finally to reduce the principal amount of outstanding
         Loans.

                  (e) FAILURE TO PAY AGENT. Unless Agent shall have received
         notice from Borrower at

<PAGE>

         least one (1) Business Day prior to the date on which any payment is
         due to the Lenders hereunder that Borrower will not make such
         payment in full, Agent shall be entitled to assume that Borrower has
         made or will make such payment in full to Agent on such date and
         Agent may, in reliance upon such assumption, cause to be paid to the
         Lenders on such due date an amount equal to the amount then due such
         Lenders. If and to the extent Borrower shall not have so made such
         payment in full to Agent, each such Lender shall repay to Agent
         forthwith on demand such amount distributed to such Lender together
         with interest thereon, for each day from the date such amount is
         distributed to such Lender until the date such Lender repays such
         amount to Agent, at (i) the Federal Funds Rate for the first three (3)
         days and (ii) the per annum rate applicable to Base Rate Loans
         thereafter. A certificate of Agent submitted to any Lender with respect
         to any amounts owing by such Lender under this SUBPARAGRAPH 2.05(e)
         shall be conclusive absent manifest error.

         2.6.    NOTES AND INTEREST ACCOUNT.

                  (a) NOTES. The obligation of Borrower to repay the Loans made
         by each Lender and to pay interest thereon at the rates provided herein
         shall be evidenced by a promissory note in the form of EXHIBIT E
         (individually, an "AMENDED AND RESTATED NOTE") which note shall be (i)
         payable to the order of such Lender, (ii) in the amount of such
         Lender's Commitment, (iii) dated the Closing Date and (iv) otherwise
         appropriately completed. Borrower authorizes each Lender to record on
         the schedule annexed to such Lender's Amended and Restated Note the
         date and amount of each Loan made by such Lender and of each payment or
         prepayment of principal thereon made by Borrower, and agrees that all
         such notations shall constitute prima facie evidence of the matters
         noted; PROVIDED, HOWEVER, that any failure by a Lender to make any such
         notation shall not affect the Obligations. Borrower further authorizes
         each Lender to attach to and make a part of such Lender's Amended and
         Restated Note continuations of the schedule attached thereto as
         necessary.

                  (b) INTEREST ACCOUNT. Borrower authorizes Agent to record in
         an account or accounts maintained by Agent on its books (the "INTEREST
         ACCOUNT") (i) the interest rates applicable to all Loans and the
         effective dates of all changes thereto, (ii) the Interest Period for
         each LIBOR Loan, (iii) the date and amount of each principal and
         interest payment on each Loan and (iv) such other information as Agent
         may determine is necessary for the computation of interest payable by
         Borrower hereunder.

         2.7.    LOAN FUNDING.

                  (a) LENDER FUNDING AND DISBURSEMENT TO BORROWER. Each Lender
         shall, before 12:00 noon on the date of each Borrowing, make available
         to Agent at Agent's office specified in PARAGRAPH 8.01, in same day or
         immediately available funds, such Lender's Proportionate Share of such
         Borrowing. After Agent's receipt of such funds and upon satisfaction of
         the applicable conditions set forth in SECTION III, Agent shall
         promptly disburse such funds to Borrower in same day or immediately
         available funds. Unless

<PAGE>

         otherwise directed by Borrower, Agent shall disburse the proceeds of
         each Borrowing by disbursement to the account or accounts specified
         in the applicable Notice of Borrowing.

                  (b) LENDER FAILURE TO FUND. Unless Agent shall have received
         notice from a Lender prior to the date of any Borrowing that such
         Lender will not make available to Agent such Lender's Proportionate
         Share of such Borrowing, Agent shall be entitled to assume that such
         Lender has made or will make such portion available to Agent on the
         date of such Borrowing in accordance with SUBPARAGRAPH 2.07(a), and
         Agent may on such date, in reliance upon such assumption, disburse or
         otherwise credit to Borrower a corresponding amount. If any Lender does
         not make the amount of its Proportionate Share of any Borrowing
         available to Agent on or prior to the date of such Borrowing, such
         Lender shall pay to Agent, on demand, interest which shall accrue on
         such amount from the date of such Borrowing until such amount is paid
         to Agent at rates equal to (i) the daily Federal Funds Rate during the
         period from the date of such Borrowing through the third Business Day
         thereafter and (ii) the rate applicable to Base Rate Loans thereafter.
         A certificate of Agent submitted to any Lender with respect to any
         amounts owing under this SUBPARAGRAPH 2.07(b) shall be conclusive
         absent manifest error. If the amount of any Lender's Proportionate
         Share of any Borrowing is not paid to Agent by such Lender within three
         (3) Business Days after the date of such Borrowing, Borrower shall
         repay such amount to Agent, on demand, together with interest thereon,
         for each day from the date such amount was disbursed to Borrower until
         the date such amount is repaid to Agent, at the interest rate
         applicable at the time to the Loans comprising such Borrowing.

                  (c) LENDERS' OBLIGATIONS SEVERAL. The failure of any Lender to
         make the Loan to be made by it as part of any Borrowing shall not
         relieve any other Lender of its obligation hereunder to make its Loan
         on the date of such Borrowing, but no Lender shall be obligated in any
         way to make any Loan which another Lender has failed or refused to make
         or otherwise be in any way responsible for the failure or refusal of
         any other Lender to make any Loan required to be made by such other
         Lender on the date of any Borrowing.

         2.8.    PRO RATA TREATMENT.

                  (a) BORROWINGS, COMMITMENT REDUCTIONS, ETC.  Except as
         otherwise provided herein:

                           (i) Each Borrowing and reduction of the Total
                  Commitment shall be made or shared among the Lenders pro rata
                  according to their respective Proportionate Shares;

                           (ii) Each payment of principal of Loans in any
                  Borrowing shall be shared among the Lenders which made or
                  funded the Loans in such Borrowing pro rata according to the
                  respective unpaid principal amounts of such Loans so made or
                  funded by such Lenders;

                           (iii) Each payment of interest on Loans in any
                  Borrowing shall be shared among the Lenders which made or
                  funded the Loans in such Borrowing pro rata

<PAGE>

                  according to (A) the respective unpaid principal amounts of
                  such Loans so made or funded by such Lenders and (B) the
                  dates on which such Lenders so made or funded such Loans;

                           (iv) Each payment of Commitment Fees shall be shared
                  among the Lenders pro rata according to (A) their respective
                  Proportionate Shares and (B) in the case of each Lender which
                  becomes a Lender hereunder after the date hereof, the date
                  upon which such Lender so became a Lender;

                           (v) Each payment of interest (other than interest on
                  Loans) shall be shared among the Lenders and Agent owed the
                  amount upon which such interest accrues pro rata according to
                  (A) the respective amounts so owed such Lenders and Agent and
                  (B) the dates on which such amounts became owing to such
                  Lenders and Agent; and

                           (vi) All other payments under this Agreement and the
                  other Credit Documents shall be for the benefit of the Person
                  or Persons specified.

                  (b) SHARING OF PAYMENTS, ETC. If any Lender shall obtain any
         payment (whether voluntary, involuntary, through the exercise of any
         right of setoff, or otherwise) on account of Loans owed to it in excess
         of its ratable share of payments on account of such Loans obtained by
         all Lenders entitled to such payments, such Lender shall forthwith
         purchase from the other Lenders such participations in the Loans as
         shall be necessary to cause such purchasing Lender to share the excess
         payment ratably with each of them; PROVIDED, HOWEVER, that if all or
         any portion of such excess payment is thereafter recovered from such
         purchasing Lender, such purchase shall be rescinded and each other
         Lender shall repay to the purchasing Lender the purchase price to the
         extent of such recovery together with an amount equal to such other
         Lender's ratable share (according to the proportion of (i) the amount
         of such other Lender's required repayment to (ii) the total amount so
         recovered from the purchasing Lender) of any interest or other amount
         paid or payable by the purchasing Lender in respect of the total amount
         so recovered. Borrower agrees that any Lender so purchasing a
         participation from another Lender pursuant to this SUBPARAGRAPH 2.08(b)
         may, to the fullest extent permitted by law, exercise all its rights of
         payment (including the right of setoff) with respect to such
         participation as fully as if such Lender were the direct creditor of
         Borrower in the amount of such participation.

         2.09.    CHANGE OF CIRCUMSTANCES.

                  (a) INABILITY TO DETERMINE RATES. If, on or before the first
         day of any Interest Period for any LIBOR Loan, (i) any Lender shall
         advise Agent that the LIBO Rate for such Interest Period cannot be
         adequately and reasonably determined due to the unavailability of funds
         in or other circumstances affecting the London interbank market or (ii)
         any Lender shall advise Agent that the rate of interest for such Loan
         does not adequately and fairly reflect the cost to such Lender of
         making or maintaining such LIBOR Loan, Agent shall immediately give
         notice of such condition to Borrower and the other Lenders. After the
         giving of any such notice and until Agent shall otherwise notify
         Borrower that the

<PAGE>

         circumstances giving rise to such condition no longer exist,
         Borrower's right to request the making of or conversion to, and the
         Lenders' obligations to make or convert to LIBOR Loans shall be
         suspended. Any LIBOR Loans outstanding at the commencement of any such
         suspension shall be converted at the end of the then current Interest
         Period for such LIBOR Loans into a Base Rate Loans unless such
         suspension has then ended.

                  (b) ILLEGALITY. If, after the date of this Agreement, the
         adoption of any Governmental Rule, any change in any Governmental Rule
         or the application or requirements thereof (whether such change occurs
         in accordance with the terms of such Governmental Rule as enacted, as a
         result of amendment or otherwise), any change in the interpretation or
         administration of any Governmental Rule by any Governmental Authority,
         or compliance by any Lender with any request or directive (whether or
         not having the force of law) of any Governmental Authority (a "CHANGE
         OF LAW") shall make it unlawful or impossible for any Lender to make or
         maintain any LIBOR Loan, such Lender shall immediately notify Agent and
         Borrower of such Change of Law. Upon receipt of such notice, (i)
         Borrower's right to request the making of or conversion to, and such
         Lender's obligation to make or convert to LIBOR Loans shall be
         terminated, and (ii) Borrower shall, at the request of such Lender,
         either (A) pursuant to SUBPARAGRAPH 2.01(d) convert any such then
         outstanding LIBOR Loans into Base Rate Loans at the end of the current
         Interest Period for such LIBOR Loans or (B) immediately repay or
         convert any such LIBOR Loans if such Lender shall notify Borrower that
         such Lender may not lawfully continue to fund and maintain such LIBOR
         Loans. Any conversion or prepayment of LIBOR Loans made pursuant to the
         preceding sentence prior to the last day of an Interest Period for such
         LIBOR Loans shall be deemed a prepayment thereof for purposes of
         PARAGRAPH 2.11. After any Lender notifies Agent and Borrower of such a
         Change of Law and until such Lender notifies Agent and Borrower that it
         is no longer unlawful or impossible for such Lender to make or maintain
         a LIBOR Loan, all Loans of such Lender shall be Base Rate Loans.

                  (c) INCREASED COSTS. If, after the date of this Agreement, any
         Change of Law:

                           (i) Shall subject any Lender to any tax, duty or
                  other charge with respect to any LIBOR Loan, or shall change
                  the basis of taxation of payments by Borrower to any Lender on
                  such a LIBOR Loan or in respect to such a LIBOR Loan under
                  this Agreement (except for changes in the rate of taxation on
                  the overall net income of any Lender imposed by its
                  jurisdiction of incorporation or the jurisdiction in which its
                  principal executive office is located); or

                           (ii) Shall impose, modify or hold applicable any
                  reserve (excluding any Reserve Requirement or other reserve to
                  the extent included in the calculation of the LIBO Rate for
                  any Loans), special deposit or similar requirement against
                  assets held by, deposits or other liabilities in or for the
                  account of, advances or loans by, or any other acquisition of
                  funds by any Lender for any LIBOR Loan; or

                           (iii) Shall impose on any Lender any other condition
                  related to any LIBOR

<PAGE>

                  Loan or such Lender's Commitment;

         And the effect of any of the foregoing is to increase the cost to such
         Lender of making, renewing, or maintaining any such LIBOR Loan or its
         Commitment or to reduce any amount receivable by such Lender hereunder;
         then Borrower shall from time to time, within five (5) days after
         demand by such Lender, pay to such Lender additional amounts sufficient
         to reimburse such Lender for such increased costs or to compensate such
         Lender for such reduced amounts. A certificate as to the amount of such
         increased costs or reduced amounts, submitted by such Lender to
         Borrower shall, in the absence of manifest error, be conclusive and
         binding on Borrower for all purposes. The obligations of Borrower under
         this SUBPARAGRAPH 2.09(c) shall survive the payment and performance of
         the Obligations and the termination of this Agreement.

                  (d) CAPITAL REQUIREMENTS. If, after the date of this
         Agreement, any Lender determines that (i) any Change of Law affects the
         amount of capital required or expected to be maintained by such Lender
         or any Person controlling such Lender (a "CAPITAL ADEQUACY
         REQUIREMENT") and (ii) the amount of capital maintained by such Lender
         or such Person which is attributable to or based upon the Loans, the
         Commitments or this Agreement must be increased as a result of such
         Capital Adequacy Requirement (taking into account such Lender's or such
         Person's policies with respect to capital adequacy), Borrower shall pay
         to such Lender or such Person, within five (5) days after demand of
         such Lender, such amounts as such Lender or such Person shall determine
         are necessary to compensate such Lender or such Person for the
         increased costs to such Lender or such Person of such increased
         capital. A certificate of any Lender setting forth in reasonable detail
         the computation of any such increased costs, delivered by such Lender
         to Borrower shall, in the absence of manifest error, be conclusive and
         binding on Borrower for all purposes. The obligations of Borrower under
         this SUBPARAGRAPH 2.09(d) shall survive the payment and performance of
         the Obligations and the termination of this Agreement.

                  (e) MITIGATION. Any Lender which becomes aware of (i) any
         Change of Law which will make it unlawful or impossible for such Lender
         to make or maintain any LIBOR Loan or (ii) any Change of Law or other
         event or condition which will obligate Borrower to pay any amount
         pursuant to SUBPARAGRAPH 2.09(c) or SUBPARAGRAPH 2.09(d) shall notify
         Borrower and Agent thereof as promptly as practical. If any Lender has
         given notice of any such Change of Law or other event or condition and
         thereafter becomes aware that such Change of Law or other event or
         condition has ceased to exist, such Lender shall notify Borrower and
         Agent thereof as promptly as practical. Each Lender affected by any
         Change of Law which makes it unlawful or impossible for such Lender to
         make or maintain any LIBOR Loan or to which Borrower is obligated to
         pay any amount pursuant to SUBPARAGRAPH 2.09(c) or SUBPARAGRAPH 2.09(d)
         shall use reasonable commercial efforts (including changing the
         jurisdiction of its Applicable Lending Office) to avoid the effect of
         such Change of Law or to avoid or materially reduce any amounts which
         Borrower is obligated to pay pursuant to SUBPARAGRAPH 2.09(c) or
         SUBPARAGRAPH 2.09(d) if, in the reasonable opinion of such Lender, such
         efforts would not be disadvantageous to such Lender or contrary to such
         Lender's normal banking practices.

         2.10.    TAXES ON PAYMENTS.

                  (a) PAYMENTS FREE OF TAXES. All payments made by Borrower
         under this Agreement and the other Credit Documents shall be made free
         and clear of, and without deduction or withholding for or on account
         of, any present or future income, stamp or other taxes, levies,
         imposts, duties, charges, fees, deductions or withholdings, now or
         hereafter imposed, levied, collected, withheld or assessed by any
         Governmental Authority (except net income taxes and franchise taxes in
         lieu of net income taxes imposed on Agent or any Lender by its
         jurisdiction of incorporation or the jurisdiction in which its
         Applicable Lending Office is located) (all such non-excluded taxes,
         levies, imposts, duties, charges, fees, deductions and withholdings
         being hereinafter called "TAXES"). If any Taxes are required to be
         withheld from any amounts payable to Agent or any Lender hereunder or
         under the other Credit Documents, the amounts so payable to Agent or
         such Lender shall be increased to the extent necessary to yield to
         Agent or such Lender (after payment of all Taxes) interest or any such
         other amounts payable hereunder at the rates or in the amounts
         specified in this Agreement and the other Credit Documents. Whenever
         any Taxes are payable by Borrower, as promptly as possible thereafter,
         Borrower shall send to Agent for its own account or for the account of
         such Lender, as the case may be, a certified copy of an original
         official receipt received by Borrower showing payment thereof. If
         Borrower fails to pay any Taxes when due to the appropriate taxing
         authority or fails to remit to Agent the required receipts or other
         required documentary evidence, Borrower shall indemnify Agent and the
         Lenders for any incremental taxes, interest or penalties that may
         become payable by Agent or any Lender as a result of any such failure.
         The obligations of Borrower under this SUBPARAGRAPH 2.10(a) shall
         survive the payment and performance of the Obligations and the
         termination of this Agreement.

                  (b) WITHHOLDING EXEMPTION CERTIFICATES. On or prior to the
         date of the initial Borrowing or, if such date does not occur within
         thirty (30) days after the date of this Agreement, by the end of such
         30-day period, each Lender which is not organized under the laws of the
         United States of America or a state thereof shall deliver to Borrower
         and Agent two duly completed copies of United States Internal Revenue
         Service Form 1001 or 4224 (or successor applicable form), as the case
         may be, certifying in each case that such Lender is entitled to receive
         payments under this Agreement without deduction or withholding of any
         United States federal income taxes. Each Lender which delivers to
         Borrower and Agent a Form 1001 or 4224 pursuant to the immediately
         preceding sentence further undertakes to deliver to Borrower and Agent
         two further copies of Form 1001 or 4224 (or successor applicable
         forms), as the case may be, on or before the date that any such form
         expires or becomes obsolete or after the occurrence of any event
         requiring a change in the most recent form previously delivered by such
         Lender to Borrower and Agent, certifying that such Lender is entitled
         to receive payments under this Agreement without deduction or
         withholding of any United States federal income taxes. Each Lender
         which is not organized under the laws of the United States of America
         or a state thereof further agrees (i) promptly to notify Agent and
         Borrower of any change of circumstances (including without limitation
         any change in any treaty, law or regulation) which would prevent such
         Lender from receiving payments hereunder

<PAGE>

         without any deduction or withholding of United States federal income
         tax and (ii) to furnish to Agent and Borrower any other manner of
         certification as Agent or Borrower may reasonably request to establish
         the right of such Lender to receive payments hereunder without any
         deduction or withholding of United States federal income tax.

                  (c) MITIGATION. If Agent or any Lender claims any additional
         amounts to be payable to it pursuant to this PARAGRAPH 2.10, such
         Person shall use reasonable commercial efforts to file any certificate
         or document requested in writing by Borrower (including without
         limitation copies of Internal Revenue Service Form 1001 (or successor
         forms) reflecting a reduced rate of withholding) or to change the
         jurisdiction of its Applicable Lending Office if the making of such a
         filing or such change in the jurisdiction of its Applicable Lending
         Office would avoid the need for or materially reduce the amount of any
         such additional amounts which may thereafter accrue and if, in the
         reasonable opinion of such Person, in the case of a change in the
         jurisdiction of its Applicable Lending Office, such change would not be
         disadvantageous to such Person or contrary to such Person's normal
         banking practices.

                  (d) TAX RETURNS. Nothing contained in this PARAGRAPH 2.10
         shall require Agent or any Lender to make available any of its tax
         returns (or any other information relating to its taxes which it deems
         to be confidential).

         2.11. FUNDING LOSS INDEMNIFICATION. If Borrower shall (a) repay, prepay
or convert any LIBOR Loan on any day other than the last day of an Interest
Period therefor (whether a scheduled payment, an optional prepayment or
conversion, a mandatory prepayment or conversion, a payment upon acceleration or
otherwise), (b) fail to borrow any LIBOR Loan for which a Notice of Borrowing
has been delivered to Agent (whether as a result of the failure to satisfy any
applicable conditions or otherwise) or (c) fail to convert any Loans into LIBOR
Loans in accordance with a Notice of Conversion delivered to Agent (whether as a
result of the failure to satisfy any applicable conditions or otherwise),
Borrower shall, upon demand by any Lender, reimburse such Lender for and hold
such Lender harmless from all costs and losses incurred by such Lender as a
result of such repayment, prepayment, conversion or failure. Borrower
understands that such costs and losses may include, without limitation, losses
incurred by a Lender as a result of funding and other contracts entered into by
such Lender to fund a LIBOR Loan. Each Lender demanding payment under this
PARAGRAPH 2.11 shall deliver to Borrower, with a copy to Agent, a certificate
setting forth the amount of costs and losses for which demand is made, which
certificate shall set forth in reasonable detail the calculation of the amount
demanded. Such a certificate so delivered to Borrower shall constitute PRIMA
FACIE evidence of such costs and losses. The obligations of Borrower under this
PARAGRAPH 2.11 shall survive the payment and performance of the Obligations and
the termination of this Agreement.

         2.12.    GUARANTIES.

                  (a) GUARANTIES. The Obligations shall be secured by an Amended
         and Restated Guaranty in the form of EXHIBIT F, duly executed by each
         Domestic Subsidiary of Borrower (the "AMENDED AND RESTATED GUARANTY").

<PAGE>

                  (b) FURTHER ASSURANCES. Borrower shall deliver, or cause its
         Subsidiaries to deliver, to Agent such additional guaranties and other
         instruments, agreements, certificates, opinions and documents as
         Required Lenders may reasonably request to cause all Domestic
         Subsidiaries of Borrower to guarantee the Obligations on the terms set
         forth in the Amended and Restated Guaranty and otherwise establish,
         maintain, protect and evidence the rights provided to Agent, for the
         benefit of Agents and the Lenders, pursuant to the Amended and Restated
         Guaranty. Borrower shall fully cooperate with Agent and the Lenders and
         perform all additional acts reasonably requested by Agent or any Lender
         to effect the purposes of this PARAGRAPH 2.12.

         2.13. REPLACEMENT OF LENDERS. If any Lender shall (a) suspend its
obligation to make or maintain LIBOR Loans pursuant to SUBPARAGRAPH 2.09(b) for
a reason which is not applicable to the Lenders (or a material number of the
Lenders) generally, or (b) demand any payment under SUBPARAGRAPH 2.09(c),
2.09(d) OR 2.10(a) for a reason which is not applicable to the Lenders (or a
material number of the Lenders) generally, then Agent may (or upon the written
request of Borrower so long as no Default or Event of Default shall have
occurred and be continuing, shall) replace such Lender (the "AFFECTED LENDER"),
or cause such affected Lender to be replaced, with another lender (the
"REPLACEMENT LENDER") satisfying the requirements of an Assignee Lender under
SUBPARAGRAPH 8.05(c), by having the affected Lender sell and assign all of its
rights and obligations under this Agreement and the other Credit Documents to
the replacement lender pursuant to SUBPARAGRAPH 8.05(c); PROVIDED, HOWEVER, that
if Borrower seeks to exercise such right, it must do so within one hundred
twenty (120) days after it first knows or should have known of the occurrence of
the event or events giving rise to such right, and neither Agent nor any Lender
shall have any obligation to identify or locate a replacement lender for
Borrower. Upon receipt by any affected Lender of a written notice from Agent
stating that Agent is exercising the replacement right set forth in this
PARAGRAPH 2.1e, such affected Lender shall sell and assign all of its rights and
obligations under this Agreement and the other Credit Documents to the
replacement lender pursuant to an Assignment Agreement and SUBPARAGRAPH 8.05(c)
for a purchase price equal to the sum of the principal amount of the affected
Lender's Loans so sold and assigned, all accrued and unpaid interest thereon and
its ratable share of all fees to which it is entitled.

SECTION III.  CONDITIONS PRECEDENT.

         3.1. INITIAL CONDITIONS PRECEDENT. The obligations of the Lenders to
make the Loans comprising the initial Borrowing are subject to receipt by Agent,
on or prior to the Closing Date, of each item listed in SCHEDULE 3.01, each in
form and substance satisfactory to Agent and each Lender, and with sufficient
copies for, Agent and each Lender.

         3.2. CONDITIONS PRECEDENT TO EACH CREDIT EVENT. The occurrence of each
Credit Event (including the initial Borrowing) is subject to the further
conditions that:

                  (a) Borrower shall have delivered to Agent the Notice of
         Borrowing, Notice of Conversion or Notice of Interest Period Selection,
         as the case may be, for such Credit Event in accordance with this
         Agreement; and

<PAGE>

                  (b) On the date such Credit Event is to occur and after giving
         effect to such Credit Event, the following shall be true and correct:

                           (i) The representations and warranties of Borrower
                  and its Subsidiaries set forth in PARAGRAPH 4.01 and in the
                  other Credit Documents are true and correct in all material
                  respects as if made on such date (except for representations
                  and warranties expressly made as of a specified date, which
                  shall be true as of such date);

                           (ii) No Default or Event of Default has occurred and
                  is continuing or will result from such Credit Event; and

                           (iii) All of the Credit Documents are in full force
                  and effect.

         The submission by Borrower to Agent of each Notice of Borrowing, each
         Notice of Conversion (other than a notice for a conversion to a Base
         Rate Loan) and each Notice of Interest Period Selection shall be deemed
         to be a representation and warranty by Borrower that each of the
         statements set forth above in this SUBPARAGRAPH 3.02(b) is true and
         correct as of the date of such notice.

         3.3. COVENANT TO DELIVER. Borrower agrees (not as a condition but as a
covenant) to deliver to Agent each item required to be delivered to Agent as a
condition to the occurrence of any Credit Event if such Credit Event occurs.
Borrower expressly agrees that the occurrence of any such Credit Event prior to
the receipt by Agent of any such item shall not constitute a waiver by Agent or
any Lender of Borrower's obligation to deliver such item.

SECTION IV.   REPRESENTATIONS AND WARRANTIES.

         4.1. BORROWER'S REPRESENTATIONS AND WARRANTIES. In order to induce
Agent and the Lenders to enter into this Agreement, Borrower hereby represents
and warranties to Agent and the Lenders as follows:

                  (a) DUE INCORPORATION, QUALIFICATION, ETC. Each of Borrower
         and Borrower's Subsidiaries (i) is a corporation duly organized,
         validly existing and in good standing under the laws of its
         jurisdiction of organization; (ii) has the power and authority to own,
         lease and operate its properties and carry on its business as now
         conducted; and (iii) is duly qualified, licensed to do business and in
         good standing as a foreign corporation in each jurisdiction where the
         failure to be so qualified or licensed is reasonably likely to have a
         Material Adverse Effect.

                  (b) AUTHORITY. The execution, delivery and performance by
         Borrower of each Credit Document executed, or to be executed, by
         Borrower and the consummation of the transactions contemplated thereby
         (i) are within the power of Borrower and (ii) have been duly authorized
         by all necessary actions on the part of Borrower.

                  (c) ENFORCEABILITY. Each Credit Document executed, or to be
         executed, by Borrower

<PAGE>

         has been, or will be, duly executed and delivered by Borrower and
         constitutes, or will constitute, a legal, valid and binding obligation
         of Borrower, enforceable against Borrower in accordance with its terms,
         except as limited by bankruptcy, insolvency or other laws of general
         application relating to or affecting the enforcement of creditors'
         rights generally and general principles of equity.

                  (d) NON-CONTRAVENTION. The execution and delivery by Borrower
         of the Credit Documents executed by Borrower and the performance and
         consummation of the transactions contemplated thereby do not (i)
         violate any Requirement of Law applicable to Borrower; (ii) violate any
         provision of, or result in the breach or the acceleration of, or
         entitle any other Person to accelerate (whether after the giving of
         notice or lapse of time or both), any Contractual Obligation of
         Borrower; or (iii) result in the creation or imposition of any Lien (or
         the obligation to create or impose any Lien) upon any property, asset
         or revenue of Borrower (except such Liens as may be created in favor of
         Agent pursuant to this Agreement or the other Credit Documents).

                  (e) APPROVALS. No consent, approval, order or authorization
         of, or registration, declaration or filing with, any Governmental
         Authority or other Person (including, without limitation, the
         shareholders of any Person) is required in connection with the
         execution and delivery of the Credit Documents executed by Borrower and
         the performance and consummation of the transactions contemplated
         thereby, except such as have been made or obtained and are in full
         force and effect.

                  (f) NO VIOLATION OR DEFAULT. Neither Borrower nor any of its
         Subsidiaries is in violation of or in default with respect to (i) any
         Requirement of Law applicable to such Person; (ii) any Contractual
         Obligation of such Person (nor is there any waiver in effect which, if
         not in effect, would result in such a violation or default), where, in
         each case, such violation or default is reasonably likely to have a
         Material Adverse Effect. Without limiting the generality of the
         foregoing, neither Borrower nor any of its Subsidiaries (A) has
         violated any Environmental Laws, (B) has any liability under any
         Environmental Laws or (C) has received notice or other communication of
         an investigation or is under investigation by any Governmental
         Authority having authority to enforce Environmental Laws, where such
         violation, liability or investigation is reasonably likely to have a
         Material Adverse Effect. No Event of Default or Default has occurred
         and is continuing.

                  (g) LITIGATION. No actions (including, without limitation,
         derivative actions), suits, proceedings or investigations are pending
         or, to the knowledge of Borrower, threatened against Borrower or any of
         its Subsidiaries at law or in equity in any court or before any other
         Governmental Authority which (i) are reasonably likely (alone or in the
         aggregate) to have a Material Adverse Effect or (ii) seek to enjoin,
         either directly or indirectly, the execution, delivery or performance
         by Borrower of the Credit Documents or the transactions contemplated
         thereby.

                  (h) TITLE; POSSESSION UNDER LEASES. Borrower and its
         Subsidiaries own and have good and marketable title, or a valid
         leasehold interest in, all their respective properties

<PAGE>

         and assets as reflected in the most recent Financial Statements
         delivered to Agent (except those assets and properties disposed of
         in the ordinary course of business or otherwise in compliance with
         this Agreement since the date of such Financial Statements) and all
         respective assets and properties acquired by Borrower and its
         Subsidiaries since such date (except those disposed of in the
         ordinary course of business or otherwise in compliance with this
         Agreement). Such assets and properties are subject to no Lien,
         except for Permitted Liens. Each of Borrower and its Subsidiaries
         has complied with all obligations under all leases to which it is a
         party and enjoys peaceful and undisturbed possession under such
         leases except where the failure to so comply or enjoy is not
         reasonably likely to have a Material Adverse Effect.

                  (i) FINANCIAL STATEMENTS. The Financial Statements of Borrower
         and its Subsidiaries which have been delivered to Agent, (i) are in
         accordance with the books and records of Borrower and its Subsidiaries,
         which have been maintained in accordance with good business practice;
         (ii) have been prepared in conformity with GAAP; and (iii) fairly
         present the financial conditions and results of operations of Borrower
         and its Subsidiaries as of the date thereof and for the periods covered
         thereby. Neither Borrower nor any of its Subsidiaries has any
         Contingent Obligations or other outstanding obligations which are
         material in the aggregate, except as disclosed in the audited Financial
         Statements dated September 27, 1998, furnished by Borrower to Agent
         prior to the date hereof, or in the Financial Statements delivered to
         Agent pursuant to CLAUSE (i) OR (ii) OF SUBPARAGRAPH 5.01(a).

                  (j) NO AGREEMENTS TO SELL ASSETS; ETC. Neither Borrower nor
         any of its Subsidiaries has any legal obligation, absolute or
         contingent, to any Person to sell all or substantially all of the
         assets of Borrower or, except to the extent permitted pursuant to
         SUBPARAGRAPH 5.02(d) OR 5.02(e), any of its Subsidiaries (other than
         sales in the ordinary course of business), or to effect any merger,
         consolidation or other reorganization of Borrower or, except to the
         extent permitted pursuant to SUBPARAGRAPH 5.02(d) OR 5.02(e), any of
         its Subsidiaries or to enter into any agreement with respect thereto.

                  (k) EMPLOYEE BENEFIT PLANS.

                           (i) Based on the latest valuation of each Employee
                  Benefit Plan that either Borrower or any ERISA Affiliate
                  maintains or contributes to, or has any obligation under
                  (which occurred within twelve months of the date of this
                  representation), the aggregate benefit liabilities of such
                  plan within the meaning of Section 4001 of ERISA did not
                  exceed the aggregate value of the assets of such plan. Neither
                  Borrower nor any ERISA Affiliate has any liability with
                  respect to any post-retirement benefit under any Employee
                  Benefit Plan which is a welfare plan (as defined in section
                  3(1) of ERISA), other than liability for health plan
                  continuation coverage described in Part 6 of Title I(B) of
                  ERISA, which liability for health plan contribution coverage
                  is not reasonably likely to have a Material Adverse Effect.

<PAGE>

                           (ii) Each Employee Benefit Plan complies, in both
                  form and operation, in all material respects, with its terms,
                  ERISA and the IRC, and no condition exists or event has
                  occurred with respect to any such plan which would result in
                  the incurrence by either Borrower or any ERISA Affiliate of
                  any material liability, fine or penalty. Each Employee Benefit
                  Plan, related trust agreement, arrangement and commitment of
                  Borrower or any ERISA Affiliate is legally valid and binding
                  and in full force and effect. No Employee Benefit Plan is
                  being audited or investigated by any government agency or is
                  subject to any pending or threatened claim or suit. Neither
                  Borrower nor any ERISA Affiliate nor any fiduciary of any
                  Employee Benefit Plan has engaged in a prohibited transaction
                  under section 406 of ERISA or section 4975 of the IRC.

                           (iii) Neither Borrower nor any ERISA Affiliate
                  contributes to or has any material contingent obligations to
                  any Multiemployer Plan. Neither Borrower nor any ERISA
                  Affiliate has incurred any material liability (including
                  secondary liability) to any Multiemployer Plan as a result of
                  a complete or partial withdrawal from such Multiemployer Plan
                  under Section 4201 of ERISA or as a result of a sale of assets
                  described in Section 4204 of ERISA. Neither Borrower nor any
                  ERISA Affiliate has been notified that any Multiemployer Plan
                  is in reorganization or insolvent under and within the meaning
                  of Section 4241 or Section 4245 of ERISA or that any
                  Multiemployer Plan intends to terminate or has been terminated
                  under Section 4041A of ERISA.

                  (l) OTHER REGULATIONS. Borrower is not subject to regulation
         under the Investment Company Act of 1940, the Public Utility Holding
         Company Act of 1935, the Federal Power Act, any state public utilities
         code or to any other Governmental Rule limiting its ability to incur
         indebtedness.

                  (m) PATENT AND OTHER RIGHTS. Borrower and its Subsidiaries own
         or license (or could obtain such ownership or license on terms not
         materially adverse to Borrower and its Subsidiaries, taken as a whole)
         under validly existing agreements, and have the full right to license
         in the ordinary course of business as currently contemplated without
         the consent of any other Person, all patents, licenses, trademarks,
         trade names, trade secrets, service marks, copyrights and all rights
         with respect thereto, which are required to conduct their businesses as
         now conducted.

                  (n) GOVERNMENTAL CHARGES. Borrower and its Subsidiaries have
         filed or caused to be filed all tax returns which are required to be
         filed by them. Borrower and its Subsidiaries have paid, or made
         provision for the payment of, all taxes and other Governmental Charges
         which have or may have become due pursuant to said returns or otherwise
         and all other indebtedness, except such Governmental Charges or
         indebtedness, if any, which are being contested in good faith and as to
         which adequate reserves (determined in accordance with GAAP) have been
         provided or which are not reasonably likely to have a Material Adverse
         Effect if unpaid.

<PAGE>

                  (o) MARGIN STOCK. Borrower owns no Margin Stock which would
         cause it to be in violation of SUBPARAGRAPH 5.01(f).

                  (p) SUBSIDIARIES, ETC. Set forth in SCHEDULE 4.01(q) (as
         supplemented by Borrower from time to time in a written notice to
         Agent) is a complete list of all of Borrower's Subsidiaries; the
         jurisdiction of incorporation of each such Subsidiary; and the
         percentage of each such Subsidiary's outstanding Equity Securities
         owned directly by Borrower or another Subsidiary of Borrower. Except
         for such Subsidiaries, Borrower has no Subsidiaries, is not a partner
         in any partnership or a joint venturer in any joint venture.

                  (q) CATASTROPHIC EVENTS. Neither Borrower nor any of its
         Subsidiaries and none of their properties is or has been affected by
         any fire, explosion, accident, strike, lockout or other labor dispute,
         drought, storm, hail, earthquake, embargo, act of God or other casualty
         that is reasonably likely to have a Material Adverse Effect. There are
         no disputes presently subject to grievance procedure, arbitration or
         litigation under any of the collective bargaining agreements,
         employment contracts or employee welfare or incentive plans to which
         Borrower or any of its Subsidiaries is a party, and there are no
         strikes, lockouts, work stoppages or slowdowns, or, to the best
         knowledge of Borrower, jurisdictional disputes or organizing activities
         occurring or threatened which alone or in the aggregate are reasonably
         likely to have a Material Adverse Effect.

                  (r) BURDENSOME CONTRACTUAL OBLIGATIONS, ETC. Neither Borrower
         nor any of its Subsidiaries and none of their properties is subject to
         any Contractual Obligation or Requirement of Law which is reasonably
         likely to have a Material Adverse Effect.

                  (s) NO MATERIAL ADVERSE EFFECT. No event has occurred and no
         condition exists which is reasonably likely to have a Material Adverse
         Effect.

                  (t) ACCURACY OF INFORMATION FURNISHED. None of the Credit
         Documents and none of the other certificates, statements or information
         furnished to Agent or any Lender by or on behalf of Borrower or any of
         its Subsidiaries in connection with the Credit Documents or the
         transactions contemplated thereby contains or will contain any untrue
         statement of a material fact or omits or will omit to state a material
         fact necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading; PROVIDED,
         HOWEVER, that it is recognized by Agent and the Lenders that
         projections and forecasts provided and developed by Borrower, while
         reflecting Borrower's good faith projections or forecasts based upon
         methods and data Borrower believed to be reasonable and accurate when
         made, are not to be viewed as facts and that actual results during the
         period or periods covered by any such projections and forecasts may
         differ from the projected or forecasted results.

                  (u) YEAR 2000 COMPATIBILITY. Borrower and its Subsidiaries
         have reviewed the areas within their business and operations which
         could be adversely affected by, and have developed or are developing a
         program to address on a timely basis, the "Year 2000 Problem" (that is,
         the risk that computer applications used by Borrower and its
         Subsidiaries may be unable to recognize and perform properly
         date-sensitive functions

<PAGE>

         involving certain dates prior to and any date on or after December 31,
         1999), and have made related appropriate inquiry of material
         suppliers and vendors. Based on such review and program, Borrower
         believes that the "Year 2000 Problem" will not have a Material
         Adverse Effect.

         4.2. REAFFIRMATION. Borrower shall be deemed to have reaffirmed, for
the benefit of the Lenders and Agent, each representation and warranty contained
in PARAGRAPH 4.01 and in the other Credit Documents on and as of the date of
each Credit Event (except for representations and warranties expressly made as
of a specified date, which shall be true as of such date).

                  Borrower with the terms of this Agreement and the other Credit

                  (b) BOOKS AND RECORDS. Borrower and its Subsidiaries shall at

                  term of this Agreement by others engaged in substantially the
                  same business as such Person and operating in the same
                  geographic area as such Person, including, but not limited to,
                  fire, public liability, property damage and worker's

                           (iii) Deliver to Agent from time to time, as Agent
                  may request, schedules setting forth all insurance then in
                  effect.

         promptly pay and discharge when due all taxes and other Governmental
         Charges prior to the date upon which penalties accrue thereon, except
         such taxes and other Governmental Charges as may in good faith be
         contested or disputed, or for which arrangements for deferred payment
         have been made, provided that in each such case appropriate reserves
         are maintained to the reasonable satisfaction of Agent.

                  (f) USE OF PROCEEDS. Borrower shall use the proceeds of the
         Loans only for the purposes set forth in SUBPARAGRAPH 2.01(g). Borrower
         shall not use any part of the proceeds of any Loan, directly or
         indirectly, for the purpose of purchasing or carrying any Margin Stock
         or for the purpose of purchasing or carrying or trading in any
         securities under such circumstances as to involve Borrower, any Lender
         or Agent in a violation of Regulations T, U or X issued by the Federal
         Reserve Board.

                  (g) GENERAL BUSINESS OPERATIONS. Except to the extent
         otherwise permitted pursuant to SUBPARAGRAPH 5.02(d), each of Borrower
         and its Subsidiaries shall (i) preserve and maintain its corporate
         existence and all of its rights, privileges and franchises reasonably
         necessary to the conduct of its business; PROVIDED, HOWEVER, that
         Borrower may cause any wholly-owned Subsidiary to be liquidated if
         Borrower's board of directors determines that it is in the best
         interests of Borrower and its Subsidiaries, taken as a whole and the

<PAGE>

         assets of such dissolved wholly-owned Subsidiary are placed with
         Borrower or any Guarantor hereunder; (ii) conduct its business
         activities in compliance with all Requirements of Law and Contractual
         Obligations applicable to such Person, the violation of which is
         reasonably likely to have a Material Adverse Effect; and (iii) keep all
         property useful and necessary in its business in good working order and
         condition, ordinary wear and tear excepted, except where any failure to
         do so is not reasonably likely to have a Material Adverse Effect.
         Borrower shall maintain its chief executive office and principal place
         of business in the United States and shall not relocate its chief
         executive office or principal place of business outside of California
         except upon not less than ninety (90) days prior written notice to

                  (h) YEAR 2000 COMPATIBILITY. Borrower and its Subsidiaries

         material to their business operations or financial condition will
         properly perform date sensitive functions before, during and after the
         year 2000. At the request of Agent, Borrower shall provide to Agent
         such certifications or other evidence of compliance with this
         SUBPARAGRAPH 5.01(h) as Agent may from time to time require.

                  (i) PARI PASSU RANKING. Borrower shall take, or cause to be
         taken, all actions necessary to ensure that the Obligations of Borrower
         are and continue to rank at least PARI PASSU in right of payment with
         all other unsecured Indebtedness of Borrower.

         5.2. NEGATIVE COVENANTS. Until the termination of this Agreement and
the satisfaction in full by Borrower of all Obligations, Borrower will comply,
and will cause compliance, with the following negative covenants, unless
Required Lenders shall otherwise consent in writing:

                  (a) INDEBTEDNESS. Neither Borrower nor any of its Subsidiaries
         shall create, incur, assume or permit to exist any Indebtedness except
         for the following ("PERMITTED INDEBTEDNESS"):

                           (i)   The Obligations of Borrower under the Credit
                  Documents;

                           (ii)  Indebtedness of Borrower and its Subsidiaries

                  this Agreement;

                           (iii) Indebtedness of Borrower and its Subsidiaries
                  arising from the endorsement of instruments for collection in
                  the ordinary course of Borrower's or a Subsidiary's business;

                           (iv)  Indebtedness of Borrower and its Subsidiaries
                  under Rate Contracts, provided that (A) all such arrangements

payable by Borrower to be immediately due and payable without presentment,

Notes to the contrary notwithstanding. Upon the occurrence or existence of

immediately and without notice, (1) the Commitments and the obligations of

SECTION VII.          THE AGENT AND RELATIONS AMONG LENDERS.

         7.1. APPOINTMENT, POWERS AND IMMUNITIES. Each Lender hereby appoints
and authorizes Agent to act as its agent hereunder and under the other Credit
Documents with such powers as are expressly delegated to Agent by the terms
of this Agreement and the other Credit Documents, together with such other
powers as are reasonably incidental thereto. Agent shall not have any duties
or responsibilities except those expressly set forth in this Agreement or in
any other Credit Document, be a trustee for any Lender or have any fiduciary
duty to any Lender. Notwithstanding anything to the contrary contained herein
Agent shall not be required to take any action which is contrary to this
Agreement or any other Credit Document or any applicable Governmental Rule.
Neither Agent nor any Lender shall be responsible to any other Lender for any
recitals, statements, representations or warranties made by Borrower or any
of its Subsidiaries contained in this Agreement or in any other Credit
Document, for the value, validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Credit Document or for any
failure by Borrower or any of its Subsidiaries to perform their respective
obligations hereunder or thereunder. Agent may employ agents and
attorneys-in-fact

<PAGE>

and shall not be responsible to any Lender for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.
Neither Agent nor any of its directors, officers, employees, agents or
advisors shall be responsible to any Lender for any action taken or omitted
to be taken by it or them hereunder or under any other Credit Document or in
connection herewith or therewith, except for its or their own gross
negligence or willful misconduct. Except as otherwise provided under this
Agreement, Agent shall take such action with respect to the Credit Documents
as shall be directed by the Required Lenders.

         7.2. RELIANCE BY AGENT. Agent shall be entitled to rely upon any
certificate, notice or other document (including any cable, telegram,
facsimile or telex) believed by it in good faith to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel, independent
accountants and other experts selected by Agent with reasonable care. As to
any other matters not expressly provided for by this Agreement, Agent shall
not be required to take any action or exercise any discretion, but shall be
required to act or to refrain from acting upon instructions of the Required
Lenders and shall in all cases be fully protected by the Lenders in acting,
or in refraining from acting, hereunder or under any other Credit Document in
accordance with the instructions of the Required Lenders, and such
instructions of the Required Lenders and any action taken or failure to act
pursuant thereto shall be binding on all of the Lenders.

         7.3. DEFAULTS. Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default unless Agent has
received a written notice from a Lender or Borrower, referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "Notice of Default". If Agent receives such a notice of the
occurrence of a Default or Event of Default, Agent shall give prompt notice
thereof to the Lenders. Agent shall take such action with respect to such
Default or Event of Default as shall be reasonably directed by the Required
Lenders; PROVIDED, HOWEVER, that until Agent shall have received such
directions, Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lenders.

         7.4. INDEMNIFICATION. Without limiting the Obligations of Borrower
hereunder, each Lender agrees to indemnify Agent, ratably in accordance with
their Proportionate Shares, for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may at any time be
imposed on, incurred by or asserted against Agent in any way relating to or
arising out of this Agreement or any documents contemplated by or referred to
herein or therein or the transactions contemplated hereby or thereby or the
enforcement of any of the terms hereof or thereof; PROVIDED, HOWEVER, that no
Lender shall be liable for any of the foregoing to the extent they arise from
Agent's gross negligence or willful misconduct. Agent shall be fully
justified in refusing to take or in continuing to take any action hereunder
unless it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. The obligations of
each Lender under this PARAGRAPH 7.04 shall survive the payment and
performance of the Obligations, the termination of this Agreement and any
Lender ceasing to be a party to this Agreement (with respect to events

<PAGE>

which occurred prior to the time such Lender ceased to be a Lender hereunder).

         7.5. NON-RELIANCE. Each Lender represents that it has, independently
and without reliance on Agent, or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own
appraisal of the business, prospects, management, financial condition and
affairs of Borrower and the Subsidiaries and its own decision to enter into
this Agreement and agrees that it will, independently and without reliance
upon Agent or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own appraisals
and decisions in taking or not taking action under this Agreement. Neither
Agent nor any of its affiliates nor any of their respective directors,
officers, employees, agents or advisors shall (a) be required to keep any
Lender informed as to the performance or observance by Borrower or any of its
Subsidiaries of the obligations under this Agreement or any other document
referred to or provided for herein or to make inquiry of, or to inspect the
properties or books of Borrower or any of its Subsidiaries; (b) have any duty
or responsibility to provide any Lender with any credit or other information
concerning Borrower or any of its Subsidiaries which may come into the
possession of Agent, except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by Agent
hereunder; or (c) be responsible to any Lender for (i) any recital,
statement, representation or warranty made by Borrower or any officer,
employee or agent of Borrower in this Agreement or in any of the other Credit
Documents, (ii) the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any Credit Document, or
(iii) any failure by Borrower to perform its obligations under this Agreement
or any other Credit Document.

         7.6. RESIGNATION OR REMOVAL OF AGENT. Agent may resign at any time
by giving thirty (30) days prior written notice thereof to Borrower and the
Lenders, and Agent may be removed at any time with or without cause by the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint a successor Agent, which Agent, if not a
Lender, shall be reasonably acceptable to Borrower; PROVIDED, HOWEVER, that
Borrower shall have no right to approve a successor Agent if a Default or an
Event of Default has occurred and is continuing. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from the duties and obligations thereafter arising hereunder.
After any retiring Agent's resignation or removal hereunder as Agent, the
provisions of this SECTION VII shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting
as Agent.

         7.7. AUTHORIZATION. Agent is hereby authorized by the Lenders to
execute, deliver and perform, each of the Credit Documents to which Agent is
or is intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

         7.8. AGENT IN ITS INDIVIDUAL CAPACITY. Agent and its affiliates may
make loans to, accept deposits from and generally engage in any kind of
banking or other business with Borrower and its Subsidiaries and affiliates
as though Agent were not Agent hereunder. With respect to Loans, if any, made
by Agent in its capacity as a Lender, Agent in its capacity as a Lender shall
have the same rights and powers under this Agreement and the other Credit
Documents as any other

<PAGE>

Lender and may exercise the same as though it were not Agent, and the terms
"Lender" or "Lenders" shall include Agent in its capacity as a Lender.

SECTION VIII.         MISCELLANEOUS.

         8.1. NOTICES. Except as otherwise provided herein, all notices,

Each Notice of Borrowing, Notice of Conversion and Notice of Interest Period
Selection shall be given by Borrower to Agent's office located at the address
referred to above during Agent's normal business hours; PROVIDED, HOWEVER,
that any such notice received by Agent after 10:30 a.m. on any Business Day
shall be deemed received by Agent on the next Business Day. In any case where
this Agreement authorizes notices, requests, demands or other communications
by Borrower to Agent or any Lender to be made by telephone or facsimile,
Agent or any Lender may conclusively presume that anyone purporting to be a
person designated in any incumbency certificate or other similar document
received by Agent or a Lender is such a person.

         8.2. EXPENSES. Borrower shall pay on demand, whether or not any Loan
is made hereunder, (a) all reasonable fees and expenses, including reasonable
attorneys' fees and expenses, incurred by Agent in connection with the
preparation, negotiation, execution and delivery of, and the exercise of its
duties under, this Agreement and the other Credit Documents, and the
preparation, negotiation, execution and delivery of amendments and waivers
hereunder and thereunder and (b) all reasonable fees and expenses, including
reasonable attorneys' fees and expenses, incurred by Agent and the Lenders in
the enforcement or attempted enforcement of any of the Obligations or in
preserving any of Agent's or the Lenders' rights and remedies (including,
without limitation, all such fees and expenses incurred in connection with
any "workout" or restructuring affecting the Credit Documents or the
Obligations or any bankruptcy or similar proceeding involving Borrower or any
of its Subsidiaries). As used herein, the term "reasonable attorneys' fees
and expenses" shall include, without limitation, allocable costs and expenses
of Agent's and Lenders' in-house legal counsel and staff. The obligations of
Borrower under this PARAGRAPH 8.02 shall survive the payment and performance
of the Obligations and the termination of this Agreement.

         8.3. INDEMNIFICATION. To the fullest extent permitted by law,
Borrower agrees to protect, indemnify, defend and hold harmless Agent, the
Lenders and their Affiliates and their respective directors, officers,
employees, agents and advisors ("INDEMNITEES") from and against any and all
liabilities, losses, damages or expenses of any kind or nature and from any
suits, claims or demands (including in respect of or for reasonable
attorney's fees and other expenses) arising on account of or in connection
with any matter or thing or action or failure to act by Indemnitees, or any
of them, arising out of or relating to the Credit Documents or any
transaction contemplated thereby, including without limitation any use by
Borrower of any proceeds of the Loans, except to the extent such liability
arises from the willful misconduct or gross negligence of such Indemnitee.
Upon receiving knowledge of any suit, claim or demand asserted by a third
party that Agent or any Lender believes is covered by this indemnity, Agent
or such Lender shall give Borrower notice of the matter and an opportunity to
defend it, at Borrower's sole cost and expense, with legal counsel
satisfactory to Agent or such Lender, as the case may be. Agent or

<PAGE>

such Lender may also require Borrower to defend the matter. Any failure or
delay of Agent or any Lender to notify Borrower of any such suit, claim or
demand shall not relieve Borrower of its obligations under this PARAGRAPH
8.03 but shall reduce such obligations to the extent of any increase in those
obligations caused solely by any such failure or delay which is unreasonable.
The obligations of Borrower under this PARAGRAPH 8.03 shall survive the
payment and performance of the Obligations and the termination of this
Agreement.

         8.4. WAIVERS; AMENDMENTS. Any term, covenant, agreement or condition
of this Agreement or any other Credit Document may be amended or waived, and
any consent under this Agreement or any other Credit Document may be given,
if such amendment, waiver or consent is in writing and is signed by Borrower
and the Required Lenders (or Agent on behalf of the Required Lenders with the
written approval of the Required Lenders); PROVIDED, HOWEVER that:

                  (a) Any amendment, waiver or consent which would (i) increase
         the Total Commitment, (ii) extend the Maturity Date, (iii) reduce the
         principal of or interest on any Loan or any fees or other amounts
         payable for the account of the Lenders hereunder, (iv) extend any
         scheduled principal, interest or fee payment date, (v) amend this
         PARAGRAPH 8.04, (vi) releases the Amended and Restated Guaranty, or
         (vii) amends the definition of Required Lenders, must be in writing and
         signed or approved in writing by all Lenders;

                  (b) Any amendment, waiver or consent which increases or
         decreases the Proportionate Share of any Lender must be in writing and
         signed by such Lender; and

                  (c) Any amendment, waiver or consent which affects the rights
         or obligations of Agent must be in writing and signed by Agent.

No failure or delay by Agent or any Lender in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or
of any other right hereunder or thereunder nor shall any single or partial
exercise of any such right preclude any other further exercise thereof or of
any other right hereunder or thereunder. Unless otherwise specified in such
waiver or consent, a waiver or consent given hereunder shall be effective
only in the specific instance and for the specific purpose for which given.

         8.5.    SUCCESSORS AND ASSIGNS.

                  (a) BINDING EFFECT. This Agreement and the other Credit
         Documents shall be binding upon and inure to the benefit of Borrower,
         the Lenders, Agent, all future holders of the Amended and Restated
         Notes and their respective successors and permitted assigns, except
         that Borrower may not assign or transfer any of its rights or
         obligations under any Credit Document without the prior written consent
         of Agent and each Lender. All references in this Agreement to any
         Person shall be deemed to include all successors and assigns of such
         Person.

                  (b) PARTICIPATIONS. Any Lender may at any time sell to one or
         more banks or other financial institutions ("PARTICIPANTS")
         participating interests in any Loan owing to such

<PAGE>

         Lender, any Amended and Restated Note held by such Lender, any
         Commitment of such Lender or any other interest of such Lender
         under this Agreement and the other Credit Documents. In the event of
         any such sale by a Lender of participating interests, such Lender's
         obligations under this Agreement shall remain unchanged, such Lender
         shall remain solely responsible for the performance thereof, such
         Lender shall remain the holder of its Amended and Restated Notes for
         all purposes under this Agreement and Borrower and Agent shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Agreement. Any
         agreement pursuant to which any such sale is effected may require
         the selling Lender to obtain the consent of the Participant in order
         for such Lender to agree in writing to any amendment, waiver or
         consent of a type specified in CLAUSE (i), (ii), (iii) OR (iv)
         OF SUBPARAGRAPH 8.04(a) but may not otherwise require the selling
         Lender to obtain the consent of such Participant to any other
         amendment, waiver or consent hereunder. Borrower also agrees that any
         Lender which has transferred any participating interest in its
         Commitment or Loans shall, notwithstanding any such transfer, be
         entitled to the full benefits accorded such Lender under PARAGRAPH
         2.09, Paragraph 2.10, and PARAGRAPH 2.11, as if such Lender had not
         made such transfer.

                  (c) ASSIGNMENTS. Any Lender may, at any time, sell and assign
         to any Lender or any Eligible Assignee (individually, an "ASSIGNEE
         LENDER") all or a portion of its rights and obligations under this
         Agreement and the other Credit Documents (such a sale and assignment to
         be referred to herein as an "ASSIGNMENT") pursuant to an assignment
         agreement in the form of EXHIBIT G (an "ASSIGNMENT AGREEMENT"),
         executed by each Assignee Lender and such assignor Lender (an "ASSIGNOR
         LENDER") and delivered to Agent for its acceptance and recording in the
         Register; PROVIDED, HOWEVER, that:

                           (i) Without the written consent of Agent and, if no
                  Default or Event of Default has occurred and is continuing,
                  Borrower (which consent of Agent and Borrower shall not be
                  unreasonably withheld), no Lender may make any Assignment to
                  any Assignee Lender which is not, immediately prior to such
                  Assignment, a Lender hereunder or an Affiliate thereof; or

                           (ii) Without the written consent of Agent and, if no
                  Default or Event of Default has occurred and is continuing,
                  Borrower (which consent of Agent and Borrower shall not be
                  unreasonably withheld), no Lender may make any Assignment to
                  any Assignee Lender if, after giving effect to such
                  Assignment, the Commitment of such Lender or such Assignee
                  Lender would be less than Five Million Dollars ($5,000,000)
                  (except that a Lender may make an Assignment which reduces its
                  Commitment to zero without the written consent of Borrower and
                  Agent); or

                           (iii) Without the written consent of Agent and, if no
                  Default or Event of Default has occurred and is continuing,
                  Borrower (which consent of Agent and Borrower shall not be
                  unreasonably withheld), no Lender may make any Assignment
                  which does not assign and delegate an equal pro rata interest
                  in such

<PAGE>

                  Lender's Loans, Commitment and all other rights, duties and
                  obligations of such Lender under this Agreement and the
                  other Credit Documents.

         Upon such execution, delivery, acceptance and recording of each
         Assignment Agreement, from and after the Assignment Effective Date
         determined pursuant to such Assignment Agreement, (A) each Assignee
         Lender thereunder shall be a Lender hereunder with a Proportionate
         Share as set forth on ATTACHMENT 1 TO SUCH ASSIGNMENT AGREEMENT (under
         the caption "Proportionate Share After Assignment") and shall have the
         rights, duties and obligations of such a Lender under this Agreement
         and the other Credit Documents, and (B) the Assignor Lender thereunder
         shall be a Lender with a Proportionate Share as set forth on ATTACHMENT
         1 TO SUCH ASSIGNMENT AGREEMENT (under the caption "Proportionate Share
         After Assignment"), or, if the Proportionate Share of the Assignor
         Lender has been reduced to 0%, the Assignor Lender shall cease to be a
         Lender and to have any obligation to make any Loan; PROVIDED, HOWEVER,
         that any such Assignor Lender which ceases to be a Lender shall
         continue to be entitled to the benefits of any provision of this
         Agreement which by its terms survives the termination of this
         Agreement. Each Assignment Agreement shall be deemed to amend SCHEDULE
         I to the extent, and only to the extent, necessary to reflect the
         addition of each Assignee Lender, the deletion of each Assignor Lender
         which reduces its Proportionate Share to 0% and the resulting
         adjustment of Proportionate Shares arising from the purchase by each
         Assignee Lender of all or a portion of the rights and obligations of an
         Assignor Lender under this Agreement and the other Credit Documents. On
         or prior to the Assignment Effective Date determined pursuant to each
         Assignment Agreement, Borrower, at its own expense, shall execute and
         deliver to Agent, in exchange for the surrendered Amended and Restated
         Note of the Assignor Lender thereunder, a new Amended and Restated Note
         to the order of each Assignee Lender thereunder (with each new Amended
         and Restated Note to be in an amount equal to the Commitment assumed by
         such Assignee Lender) and, if the Assignor Lender is continuing as a
         Lender hereunder, a new Amended and Restated Note to the order of the
         Assignor Lender (with the new Amended and Restated Note to be in an
         amount equal to the Commitment retained by it). Each such new Amended
         and Restated Note shall be dated the Closing Date and each shall
         otherwise be in the form of the Amended and Restated Note replaced
         thereby. The Amended and Restated Notes surrendered by the Assignor
         Lender shall be returned by Agent to Borrower marked "replaced". Each
         Assignee Lender which was not previously a Lender hereunder and which
         is not incorporated under the laws of the United States of America or a
         state thereof shall, within three (3) Business Days of becoming a
         Lender, deliver to Borrower and Agent two duly completed copies of
         United States Internal Revenue Service Form 1001 or 4224 (or successor
         applicable form), as the case may be, certifying in each case that such
         Lender is entitled to receive payments under this Agreement without
         deduction or withholding of any United States federal income taxes.

                  (d) REGISTER. Agent shall maintain at its address referred to
         in PARAGRAPH 8.01 a copy of each Assignment Agreement delivered to it
         and a register (the "REGISTER") for the recordation of the names and
         addresses of the Lenders and the Proportionate Shares of each Lender
         from time to time. The entries in the Register shall be conclusive in

<PAGE>

         the absence of manifest error, and Borrower, Agent and the Lenders may
         treat each Person whose name is recorded in the Register as the owner
         of the Loans recorded therein for all purposes of this Agreement. The
         Register shall be available for inspection by Borrower or any Lender at
         any reasonable time and from time to time upon reasonable prior notice.

                  (e) REGISTRATION. Upon its receipt of an Assignment Agreement
         executed by an Assignor Lender and an Assignee Lender (and, to the
         extent required by SUBPARAGRAPH 8.05(c), by Borrower and Agent)
         together with payment to Agent by Assignor Lender of a registration and
         processing fee of $4000, Agent shall (i) promptly accept such
         Assignment Agreement and (ii) on the Effective Date determined pursuant
         thereto record the information contained therein in the Register and
         give notice of such acceptance and recordation to the Lenders and
         Borrower. Agent may, from time to time at its election, prepare and
         deliver to the Lenders and Borrower a revised SCHEDULE I reflecting the
         names, addresses and respective Proportionate Shares of all Lenders
         then parties hereto.

                  (f) CONFIDENTIALITY. Agent and the Lenders may disclose the
         Credit Documents and any financial or other information relating to
         Borrower or any Subsidiary to each other or, with the consent of
         Borrower, to any potential Participant or Assignee Lender.

         8.6. SETOFF. In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, with the prior consent of
Agent but without prior notice to or consent of Borrower, any such notice and
consent being expressly waived by Borrower to the extent permitted by
applicable law, upon the occurrence and during the continuance of an Event of
Default, to set-off and apply against the Obligations any amount owing from
such Lender to Borrower. The aforesaid right of set-off may be exercised by
such Lender against Borrower or against any trustee in bankruptcy, debtor in
possession, assignee for the benefit of creditors, receiver or execution,
judgment or attachment creditor of Borrower or against anyone else claiming
through or against Borrower or such trustee in bankruptcy, debtor in
possession, assignee for the benefit of creditors, receiver, or execution,
judgment or attachment creditor, notwithstanding the fact that such right of
set-off may not have been exercised by such Lender at any prior time. Each
Lender agrees promptly to notify Borrower after any such set-off and
application made by such Lender, PROVIDED that the failure to give such
notice shall not affect the validity of such set-off and application.

         8.7. NO THIRD PARTY RIGHTS. Nothing expressed in or to be implied
from this Agreement is intended to give, or shall be construed to give, any
Person, other than the parties hereto and their permitted successors and
assigns hereunder, any benefit or legal or equitable right, remedy or claim
under or by virtue of this Agreement or under or by virtue of any provision
herein.

         8.8. PARTIAL INVALIDITY. If at any time any provision of this
Agreement is or becomes illegal, invalid or unenforceable in any respect
under the law or any jurisdiction, neither the legality, validity or
enforceability of the remaining provisions of this Agreement nor the
legality, validity or enforceability of such provision under the law of any
other jurisdiction shall in any way be affected or impaired thereby.

         8.9. JURY TRIAL. EACH OF BORROWER, THE LENDERS AND AGENT, TO THE

<PAGE>

FULLEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL
RIGHT TO TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION,
PROCEEDING, OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT.

         8.10. COUNTERPARTS. This Agreement may be executed in any number of
identical counterparts, any set of which signed by all the parties hereto
shall be deemed to constitute a complete, executed original for all purposes.

         8.11. CONFIDENTIALITY. None of the Banks and Agent shall disclose to
any Person any information with respect to Borrower or any of its
Subsidiaries which is furnished pursuant to this Agreement or under the other
Credit Documents, except that any Bank or Agent may disclose any such
information (a) to its own directors, officers, employees, auditors, counsel
and other professional advisors and to its Affiliates if such Bank or Agent
or such Bank's or such Agent's holding or parent company in its sole
discretion determines that any such party should have access to such
information; (b) to another Bank or Agent; (c) if generally available to the
public through no fault of Agent or the Banks; (d) if required or appropriate
in any report, statement or testimony submitted to any Governmental Authority
having or claiming to have jurisdiction over such Bank or Agent; (e) if
required or appropriate in response to any summons or subpoena or in
connection with any litigation, to the extent permitted or deemed advisable
by counsel; (f) to comply with any Requirement of Law applicable to such Bank
or Agent; (g) to any Participant or Assignee Bank or any prospective
Participant or Assignee Bank, provided that such Participant or Assignee or
prospective Participant or Assignee agrees in writing to be bound by this
PARAGRAPH 8.11 prior to disclosure; or (h) otherwise with the prior consent
of Borrower; PROVIDED, HOWEVER, that any disclosure made in violation of this
Agreement shall not affect the obligations of Borrower and its Subsidiaries
under this Agreement and the other Credit Documents.

         8.12. EFFECT; TERMINATION OF EXISTING CREDIT AGREEMENT. Borrower,
Agent and the Lenders agree that, on and after the Closing Date, (a) this
Agreement, the Amended and Restated Notes and the Amended and Restated
Guaranty shall amend, restate in their entirety and replace, without
novation, the Existing Credit Agreement, the promissory notes issued by
Borrower in connection with the Existing Credit Agreement (the "Existing
Notes") and the Guaranty dated as of July 31, 1996 issued by the Domestic
Subsidiaries in favor of Agent for the benefit of the Lenders in connection
with the Existing Credit Agreement (the "Existing Guaranty"), respectively,
(b) all obligations of the Lenders to make loans or otherwise extend credit
to Borrower under the Existing Credit Agreement shall be terminated and (c)
the Security Documents and all of the Liens granted to Agent and the Lenders
thereunder shall terminate; PROVIDED, HOWEVER, that such termination shall
not (i) operate as a waiver of any right, power or remedy of Agent or the
Lender hereunder or under the Amended and Restated Notes, the Amended and
Restated Guaranty or any related document, instrument or agreement or (ii)
extinguish or impair any obligations of Borrower under the Existing Credit
Agreement, the Existing Notes, the Existing Guaranty or any related document,
instrument or agreement except to the extent any such obligation is actually
satisfied by Borrower or is covered in this Agreement or the other Credit
Documents; PROVIDED, FURTHER, that all of the Loans

<PAGE>

outstanding under the Existing Credit Agreement shall remain outstanding and
shall be deemed to have been made under this Agreement on a pro rata basis by
the Lenders hereunder in accordance with their respective Proportionate
Shares.

                       [The first signature page follows.]

                  IN WITNESS WHEREOF, Borrower, the Lenders and Agent have

2.       The Closing Date through the quarter ending on or about June 30, 1999
         will be a Level 2 Quarter.

3.       Each quarter thereafter will be a Level 1 Quarter, a Level 2 Quarter, a
         Level 3 Quarter, a Level 4 Quarter, a Level 5 Quarter, a Level 6
         Quarter or a Level 7 Quarter depending upon Borrower's Debt/EBITDA
         Ratio for the consecutive four-quarter period which ended with the

         ADAC Laboratories, a California corporation ("BORROWER"), the Lenders
         and Agent, the Lenders have agreed to extend certain credit facilities
         to Borrower upon the terms and subject to the conditions set forth
         therein. The availability of the credit facilities under such Existing
         Credit Agreement was subject, among other conditions, to the execution
         and delivery of each Guarantor of a Guaranty dated as of July 31, 1996
         (the "EXISTING GUARANTY").

                  B. Borrower has requested Agent and the Lenders to amend the
         Existing Credit Agreement in certain respects. Pursuant to an Amended
         and Restated Credit Agreement dated the date hereof (the "CREDIT
         AGREEMENT"), among Borrower, Agent and the Lenders, Agent and the

         Guaranty as so amended in its entirety and (ii) the receipt by Agent of
         Subsidiary Joinders, duly executed by each future Domestic Subsidiary
         of Borrower. Each of the undersigned Guarantors is a Domestic
         Subsidiary of Borrower and expects to continue to derive substantial
         direct and indirect benefit from the transactions contemplated by the
         Credit Agreement.

                  2.       GUARANTY.

                           (a) PAYMENT GUARANTY. Each Guarantor unconditionally
                  guarantees and promises to pay and perform as and when due,
                  whether at stated maturity, upon acceleration or otherwise,
                  any and all of the Guaranteed Obligations. If any Insolvency
                  Proceeding relating to Borrower is commenced, each Guarantor
                  further unconditionally guarantees and promises to pay and
                  perform, upon the demand of Agent, any and all of the
                  Guaranteed Obligations (including any and all Disallowed
                  Post-Commencement Interest and Expenses) in accordance with
                  the terms of the Credit Documents, whether or not such
                  obligations are then due and payable by Borrower and whether
                  or not such obligations are modified, reduced or discharged in
                  such Insolvency Proceeding. This Guaranty is a guaranty of
                  payment and not of collection.

                           (b) CONTINUING GUARANTY. This Guaranty is an
                  irrevocable continuing guaranty of the Guaranteed Obligations
                  which shall continue in effect until all obligations of the
                  Lenders to extend credit to Borrower have terminated and all
                  of the Guaranteed Obligations have been fully, finally and
                  indefeasibly paid. If any payment on any Guaranteed Obligation
                  is set aside, avoided or rescinded or otherwise recovered from
                  Agent or any Lender, such recovered payment shall constitute a
                  Guaranteed Obligation hereunder and, if this Guaranty was
                  previously released or terminated, it automatically shall be
                  fully reinstated, as if such payment was never made.

                           (c) INDEPENDENT OBLIGATION. The liability of each
                  Guarantor hereunder is independent of the Guaranteed
                  Obligations and of the obligations of each other Guarantor
                  hereunder, and a separate action or actions may be brought and
                  prosecuted against each Guarantor irrespective of whether
                  action is brought against Borrower, any other Guarantor or any
                  other guarantor of the Guaranteed Obligations or whether
                  Borrower, any other Guarantor or any other guarantor of the
                  Guaranteed Obligations is joined in any such action or
                  actions.

                           (d) FRAUDULENT TRANSFER LIMITATION. If, in any action
                  to enforce this Guaranty, any court of competent jurisdiction
                  determines that enforcement against any Guarantor for the full
                  amount of the Guaranteed Obligations is not lawful under or
                  would be subject to avoidance under Section 548 of the United
                  States Bankruptcy Code or any applicable provision of any
                  comparable law of any state or other jurisdiction, the
                  liability of such Guarantor under this Guaranty shall be
                  limited to the maximum amount lawful and not subject to such
                  avoidance.

                           (e) TERMINATION. Notwithstanding any termination of
                  this Guaranty in accordance with PARAGRAPH 6 hereof, this
                  Guaranty shall continue to be in full force and effect and
                  applicable to any Guaranteed Obligations arising thereafter
                  which arise because prior payments of Guaranteed Obligations
                  are rescinded or otherwise required to be surrendered by Agent
                  or any Lender after receipt.

                  jurisdiction where the nature of its business or properties
                  requires such qualification, except where the failure to
                  qualify could not have a Material Adverse Effect.

                           (b) AUTHORITY. The execution, delivery and

                  necessary actions on the part of such Guarantor.

                           nonjudicial foreclosure with respect to security for
                           a Guaranteed Obligation, has destroyed such
                           Guarantor's rights of subrogation and reimbursement
                           against Borrower by the operation of Section 580d of
                           the Code of Civil Procedure or otherwise; and

                                    (xvi) All other rights and defenses
                           available to such Guarantor by reason of Sections
                           2787 to 2855, inclusive, Section 2899 or Section 3433
                           of the California Civil Code or Section 3605 of the
                           California Commercial

                           Code.

                  Without limiting the scope of any of the foregoing provisions
                  of this Paragraph 5, and pursuant to the provisions of
                  California Civil Code Section 2856, each Guarantor hereby
                  further waives all rights and defenses that such Guarantor may
                  have because the Guaranteed Obligations are secured by real
                  property. This means, among other things:

                                    (A) Agent or any Lender may collect from any
                           Guarantor without first foreclosing on any real or
                           personal property collateral pledged by Borrower.

                                    (B) If Agent or any Lender forecloses on any
                           real property collateral pledged by Borrower:

                                            (1) The amount of the Guaranteed
                                    Obligations may be reduced only by the price
                                    for which that collateral is sold at the
                                    foreclosure sale, even if the collateral is
                                    worth more than the sale price.

                                            (2) Agent or any Lender may collect
                                    from any Guarantor even if Agent or any
                                    Lender, by foreclosing on the real property
                                    collateral, has destroyed any right such
                                    Guarantor or any other Guarantor may have to
                                    collect from Borrower.

                  This is an unconditional and irrevocable waiver of any rights
                  and defenses each Guarantor may have because the Guaranteed
                  Obligations are secured by real property. These rights and
                  defenses include, but are not limited to, any rights or
                  defenses based upon Section 580a, 580b, 580d, or 726 of the
                  California Code of Civil Procedure.

                           (c) FINANCIAL CONDITION OF BORROWER, ETC. Each
                  Guarantor is fully aware of the financial condition and
                  affairs of Borrower. Each Guarantor has executed this Guaranty
                  without reliance upon any representation, warranty, statement
                  or information concerning Borrower furnished to such Guarantor
                  by Agent or any Lender and has, independently and without
                  reliance on Agent or any Lender, and based on such documents
                  and information as it has deemed appropriate, made its own
                  appraisal of the financial condition and affairs of Borrower
                  and of other circumstances affecting the risk of nonpayment or
                  nonperformance of the Guaranteed Obligations. Each Guarantor
                  is in a position to obtain, and assumes full responsibility
                  for obtaining, any additional information about the financial
                  condition and affairs of Borrower and of other circumstances
                  affecting the risk of nonpayment or nonperformance of the
                  Guaranteed Obligations and will, independently and without
                  reliance upon Agent or any Lender, and based on such documents
                  and information as it shall deem appropriate at the time,
                  continue to make its own appraisals and decisions in

                                         F-

                  taking or not taking action in connection with this Guaranty.

                  6. SUBORDINATION. Each Guarantor hereby subordinates any and
         all debts, liabilities and obligations owed to such Guarantor by
         Borrower or any Subsidiary of Borrower (the "SUBORDINATED OBLIGATIONS")
         to the Guaranteed Obligations as provided in this PARAGRAPH 6.

                           (a) PROHIBITED PAYMENTS, ETC. Until the occurrence of
                  a Default or an Event of Default or any default by any
                  Guarantor hereunder, each Guarantor and its Subsidiaries may
                  receive regularly scheduled payments from Borrower on account
                  of Subordinated Obligations. After the occurrence and during
                  the continuance of any Default or Event of Default or any
                  default by any Guarantor hereunder (including the commencement
                  and continuation of any Insolvency Proceeding relating to
                  Borrower, however, unless Agent or Required Lenders otherwise
                  requests, no Guarantor shall, nor shall it permit any of its
                  Subsidiaries to, demand, accept or take any action to collect
                  any payment on account of the Subordinated Obligations.

                           (b) PRIOR PAYMENT OF GUARANTEED OBLIGATIONS. In any
                  Insolvency Proceeding relating to Borrower, each Guarantor
                  agrees that Agent and the Lenders shall be entitled to receive
                  payment of all Guaranteed Obligations (including any and all
                  Disallowed Post-Commencement Interest and Expenses) before
                  such Guarantor or any of its Subsidiaries receives payment of
                  any Subordinated Obligations.

                           (c) TURN-OVER. After the occurrence and during the
                  continuance of any Default or Event of Default (including the
                  commencement and continuation of any Insolvency Proceeding
                  relating to Borrower, each Guarantor and its Subsidiaries
                  shall, if Agent or Required Lenders so requests, collect,
                  enforce and receive payments on account of the Subordinated
                  Obligations as trustee for Agent and the Lenders and deliver
                  such payments to Agent on account of the Guaranteed
                  Obligations (including any and all Disallowed
                  Post-Commencement Interest and Expenses), together with any
                  necessary endorsements or other instruments of transfer, but
                  without reducing or affecting in any manner the liability of
                  such Guarantor under the other provisions of this Guaranty.

                           (d) AGENT AUTHORIZATION. After the occurrence and
                  during the continuance of any Default or Event of Default or
                  any default by a Guarantor hereunder (including the
                  commencement and continuation of any Insolvency Proceeding
                  relating to Borrower, Agent is authorized and empowered (but
                  without any obligation to so do), in its discretion, (i) in
                  the name of each Guarantor and its Subsidiaries, to collect
                  and enforce, and to submit claims in respect of, Subordinated
                  Obligations and to apply any amounts received thereon to the
                  Guaranteed Obligations (including any and all Disallowed
                  Post-Commencement Interest and Expenses), and (ii) to require
                  each Guarantor (A) to collect and

                                         F-

<PAGE>

                  enforce, and to submit claims in respect of, Subordinated
                  Obligations and (B) to pay any amounts received on such
                  obligations to Agent for application to the Guaranteed
                  Obligations (including any and all Disallowed
                  Post-Commencement Interest and Expenses).

                  7.       GENERAL PLEDGE; SETOFF.

                           (a) PLEDGE. In addition to all liens upon and rights
                  of setoff against the property of any Guarantor given to Agent
                  or any Lender by law or separate agreement to secure the
                  liabilities of any Guarantor hereunder, to the extent
                  permitted by law, each Guarantor hereby grants to Agent (for
                  the ratable benefit of Agent and the Lenders), as security for
                  such Guarantor's obligations hereunder, a security interest in
                  all monies, deposit accounts, securities and other property of
                  such Guarantor now or hereafter in the possession of or on
                  deposit with Agent or any Lender, whether held in a general or
                  special account or deposit, or for safekeeping or otherwise;
                  and Agent shall have all rights and remedies of a secured
                  party with respect to such property.

                           (b) SETOFF. In addition to any rights and remedies of
                  Agent or any Lender provided by law, Agent and the Lenders
                  (with the prior consent of Agent) shall have the right,
                  without prior notice to any Guarantor, any such notice being
                  expressly waived by each Guarantor to the extent permitted by
                  applicable law, upon the occurrence and during the continuance
                  of a Default or an Event of Default, to set-off and apply
                  against the Guaranteed Obligations any amount owing from Agent
                  or any Lender to such Guarantor, including all deposits,
                  accounts and moneys of such Guarantor then or thereafter
                  maintained with Agent or any Lender, at or at any time after,
                  the happening of any of the above mentioned events.

                           (c) NONWAIVER. No security interest or right of
                  setoff shall be deemed to have been waived by any act or
                  conduct on the part of Agent or any Lender or by any failure
                  to exercise such right of setoff or to enforce such security
                  interest, or by any delay in so doing; and every right of
                  setoff and security interest shall continue in full force and
                  effect until such right of setoff or security interest is
                  specifically waived or released by an instrument in writing
                  executed by Agent.

                  8. CONTRIBUTION AMONG GUARANTORS. The Guarantors desire to
         allocate among themselves, in a fair and equitable manner, their rights
         of contribution from each other when any payment is made by any
         Guarantor under this Guaranty. Accordingly, if any payment is made by
         any Guarantor under this Guaranty (a "FUNDING GUARANTOR") that exceeds
         its Fair Share, the Funding Guarantor shall be entitled to a
         contribution from each other Guarantor in the amount of such other
         Guarantor's Fair Share Shortfall, so that all such contributions shall
         cause each Guarantor's Aggregate Guaranty Payments to equal its Fair
         Share. The amounts payable as contributions hereunder shall be
         determined by the Funding Guarantor as of the date on which the related
         payment or distribution is

                                         F-

<PAGE>

         made by the Funding Guarantor, and such determination shall be
         binding on the other Guarantors absent manifest error. The
         allocation and right of contribution among the Guarantors set forth
         in this Paragraph 8 shall not be construed to limit in any way the
         liability of any Guarantor under this Guaranty or the amount of
         the Guaranteed Obligations.

                  9.       MISCELLANEOUS.

                           (a) NOTICES. Except as otherwise provided herein, all
                  notices, requests, demands, consents, instructions or other
                  communications to or upon any Guarantor, any Lender or Agent
                  under this Guaranty or the other Credit Documents to which a
                  Guarantor is a party shall be in writing and faxed, mailed or

                  facsimile number or address set forth below or in the
                  respective Subsidiary Joinder for such Guarantor or, if to any

                  facsimile number or address for any party as indicated in any
                  notice given by that party to the other parties). All such
                  notices and communications shall be effective (i) when sent by
                  overnight service of recognized standing, on the second
                  Business Day following the deposit with such service; (ii)

                           (b) PAYMENTS. Each Guarantor shall make all payments
                  required hereunder to Agent, or its order, at Agent's office
                  located at the address set forth in SUBPARAGRAPH 9(a) hereof,
                  or at such other office as Agent may designate, on demand, in
                  Dollars. If any amounts required to be paid by a Guarantor
                  under this Guaranty are not paid when due, such Guarantor
                  shall pay interest on the aggregate, outstanding balance of
                  such amounts from the date due until those amounts are paid in
                  full at a per annum rate equal to the Base Rate plus two
                  percent (2.00%), such rate to change from time to time as the
                  Base Rate shall change.

                           (c) EXPENSES. Each Guarantor shall pay on demand (i)
                  all reasonable fees and expenses, including reasonable
                  attorneys' fees and expenses, incurred by Agent in connection
                  with the preparation, execution and delivery of, and the
                  exercise of its duties under, this Guaranty and the
                  preparation, execution and delivery of amendments and waivers
                  hereunder and (ii) all reasonable fees and expenses, including
                  reasonable attorneys' fees and expenses, incurred by Agent and
                  the Lenders in connection with the enforcement or attempted
                  enforcement of this Guaranty or any of the Guaranteed
                  Obligations or in preserving any of Agent's or the Lenders'
                  rights and remedies (including, without limitation, all such
                  fees and expenses incurred in connection with any "workout" or
                  restructuring affecting the Credit Documents or the Guaranteed
                  Obligations or any bankruptcy or similar proceeding involving
                  Guarantor, any other Guarantor, Borrower or any of their
                  affiliates).

                           (d) WAIVERS; AMENDMENTS. This Guaranty may not be
                  amended or modified, nor may any of its terms be waived,
                  except by written instruments signed by each Guarantor and
                  Agent to the extent permitted pursuant to Section 8.04 of the
                  Credit Agreement. Each waiver or consent under any provision
                  hereof shall be effective only in the specific instances for
                  the purpose for which given. No failure or delay on Agent's or
                  any Lender's part in exercising any right hereunder shall
                  operate as a waiver thereof or of any other right nor shall
                  any single or partial exercise of any such right preclude any
                  other further exercise thereof or of any other right.

                           (e) ASSIGNMENTS. This Guaranty shall be binding upon
                  and inure to

                                         F-

                  the benefit of Agent, the Lenders, the Guarantors and their
                  respective successors and assigns; PROVIDED, HOWEVER, that
                  no Guarantor may assign or transfer any of its rights and
                  obligations under this Guaranty without the prior written
                  consent of Agent and the Lenders, and, PROVIDED, FURTHER,
                  that Agent and any Lender may sell, assign and delegate their
                  respective rights and obligations hereunder only as permitted
                  by the Credit Agreement. All references in this Guaranty to
                  any Person shall be deemed to include all permitted
                  successors and assigns of such Person.

                           (f) CUMULATIVE RIGHTS, ETC. The rights, powers and
                  remedies of Agent and the Lenders under this Guaranty shall be
                  in addition to all rights, powers and remedies given to Agent
                  and the Lenders by virtue of any applicable law, rule or
                  regulation of any Governmental Authority, the Credit
                  Agreement, any other Credit Document or any other agreement,
                  all of which rights, powers, and remedies shall be cumulative
                  and may be exercised successively or concurrently without
                  impairing Agent's or any Lender's rights hereunder. Each
                  Guarantor waives any right to require Agent or any Lender to
                  proceed against any Person or to exhaust any Collateral or to
                  pursue any remedy in Agent's or such Lender's power.

                           (g) PAYMENTS FREE OF TAXES, ETC. All payments made by
                  each Guarantor under this Guaranty shall be made by each
                  Guarantor free and clear of and without deduction for any and
                  all present and future taxes, levies, charges, deductions and
                  withholdings. In addition, each Guarantor shall pay upon
                  demand any stamp or other taxes, levies or charges of any
                  jurisdiction with respect to the execution, delivery,
                  registration, performance and enforcement of this Guaranty. If
                  any taxes, levies, charges or other amounts are required to be
                  withheld from any amounts payable to Agent or any Lender
                  hereunder, the amounts so payable to Agent or such Lender
                  shall be increased to the extent necessary to yield to Agent
                  or such Lender (after payment of all such amounts) any such
                  amounts payable hereunder in the amounts specified in this
                  Guaranty. Upon request by Agent or any Lender, each Guarantor
                  shall furnish evidence satisfactory to Agent or such Lender
                  that all requisite authorizations and approvals by, and
                  notices to and filings with, governmental authorities and
                  regulatory bodies have been obtained and made and that all
                  requisite taxes, levies and charges have been paid.

                           (h) PARTIAL INVALIDITY. If at any time any provision
                  of this Guaranty is or becomes illegal, invalid or
                  unenforceable in any respect under the law or any
                  jurisdiction, neither the legality, validity or enforceability
                  of the remaining provisions of this Guaranty nor the legality,
                  validity or enforceability of such provision under the law of
                  any other jurisdiction shall in any way be affected or
                  impaired thereby.

                           (i) JOINT AND SEVERAL OBLIGATION. The obligations of
                  the Guarantors under this Guaranty are joint and several
                  obligations of each Guarantor and may be freely enforced
                  against each Guarantor, for the full amount of the Guaranteed

                                         F-

<PAGE>

                  Obligations, without regard to whether enforcement is sought
                  or available against any other Guarantor.

                           (j) GOVERNING LAW. This Guaranty shall be governed by
                  and construed in accordance with the laws of the State of
                  California without reference to conflicts of law rules.

                           (k) JURY TRIAL. EACH GUARANTOR, THE LENDERS AND
                  AGENT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
                  HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY AS TO ANY
                  ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
                  COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY.

                           (l) LIMITATION OF LIABILITY. NO CLAIM MAY BE MADE BY
                  ANY GUARANTOR AGAINST AGENT, ANY LENDER OR THE AFFILIATES,
                  DIRECTORS, OFFICERS, EMPLOYEES, ATTORNEYS OR AGENTS OF AGENT
                  OR ANY LENDER FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR
                  PUNITIVE DAMAGES IN RESPECT OF ANY CLAIM (WHETHER BASED UPON
                  ANY BREACH OF CONTRACT, TORT, BREACH OF STATUTORY DUTY OR ANY
                  OTHER THEORY OF LIABILITY) ARISING OUT OF OR RELATED TO THE
                  TRANSACTIONS CONTEMPLATED BY THIS GUARANTY, OR ANY ACT,
                  OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, AND
                  GUARANTOR HEREBY WAIVES, RELEASES AND AGREES NOT TO SUE UPON
                  ANY CLAIM FOR ANY SUCH DAMAGES, WHETHER OR NOT NOW ACCRUED AND
                  WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR.

                           (m) COUNTERPARTS. This Agreement may be executed in
                  any number of identical counterparts, any set of which signed
                  by all parties hereto shall be deemed to constitute a
                  complete, executed original for all purposes.

                  IN WITNESS WHEREOF, each Guarantor has caused this Guaranty to
         be executed as of the day and year first above written.

SECTION II.     CREDIT FACILITY.

        2.01.   REVOLVING LOAN FACILITY.

                (a) LOAN AVAILABILITY.  Subject to the terms and conditions of
        this Agreement (including the amount limitations set forth in PARAGRAPH
        2.02 and the conditions set forth in SECTION III), each Lender severally
        agrees to advance to Borrower from time to time during the period
        beginning on the Closing Date and ending on the Maturity Date such loans
        as Borrower may request under this PARAGRAPH 2.01 (individually, a
        "LOAN"); PROVIDED, HOWEVER, that (i) the aggregate principal amount of
        all Loans made by such Lender at any time outstanding shall not exceed
        such Lender's Commitment at such time and (ii) the aggregate principal
        amount of all Loans made by all Lenders at any time outstanding shall
        not exceed the Total Commitment at such time.  All Loans shall be made
        on a pro rata basis by the Lenders in accordance with their respective
        Proportionate Shares, with each Borrowing to be comprised of a Loan by
        each Lender equal to such Lender's Proportionate Share of such
        Borrowing.  Except as otherwise provided herein, Borrower may borrow,
        repay and reborrow Loans until the Maturity Date.

                (b) NOTICE OF BORROWING.  Borrower shall request each Borrowing
        by delivering to Agent an irrevocable written notice in the form of
        EXHIBIT A, appropriately completed (a "NOTICE OF BORROWING"), which
        specifies, among other things:

                        (i)     The principal amount of the requested Borrowing,
                which shall be in the amount of (A) $100,000 or an integral
                multiple of $50,000 in excess thereof in the case of a Borrowing
                consisting of Base Rate Loans; or (B) $400,000 or an integral
                multiple of $100,000 in excess thereof in the case of a
                Borrowing consisting of LIBOR Loans;

                        (ii)    Whether the requested Borrowing is to consist of
                Base Rate Loans or LIBOR Loans;

                        (iii)   If the requested Borrowing is to consist of
                LIBOR Loans, the initial Interest Period selected by Borrower
                for such Loans in accordance with SUBPARAGRAPH 2.01(e); and

                        (iv)    The date of the requested Borrowing, which shall
                be a Business Day;

        Borrower shall give each Notice of Borrowing to Agent at least three (3)
        Business Days before the date of the requested Borrowing in the case of
        a Borrowing consisting of LIBOR Loans with Interest Periods of one month
        or longer and on or before the date of the requested Borrowing in the
        case of any other Borrowing.  Each Notice of Borrowing shall be
        delivered by first-class mail or facsimile to Agent at the office or
        facsimile number and during the hours specified in PARAGRAPH 8.01;
        PROVIDED, HOWEVER, that Borrower shall promptly deliver to Agent the
        original of any Notice of Borrowing initially delivered by facsimile.
        Agent shall promptly notify each Lender of the contents


                                       22

<PAGE>

        of each Notice of Borrowing and of the amount and Type of (and, if
        applicable, the Interest Period for) each Loan to be made by such Lender
        as part of the requested Borrowing.

                (c) LOAN INTEREST RATES.  Borrower shall pay interest on the
        unpaid principal amount of each Loan from the date of such Loan until
        the maturity thereof, at one of the following rates per annum:

                        (i)     During such periods as such Loan is a Base Rate
                Loan, at a rate per annum equal to the Base Rate PLUS the
                Applicable Margin therefor, such rate to change from time to
                time as the Applicable Margin or Base Rate shall change; and

                        (ii)    During such periods as such Loan is a LIBOR
                Loan, at a rate per annum equal at all times during each
                Interest Period for such LIBOR Loan to the LIBO Rate for such
                Interest Period PLUS the Applicable Margin therefor, such rate
                to change from time to time during such Interest Period as the
                Applicable Margin shall change.

        All Loans in each Borrowing shall, at any given time prior to maturity,
        bear interest at one, and only one, of the above rates.  The number of
        Borrowings consisting of LIBOR Loans shall not exceed seven (7) at any
        time.

                (d) CONVERSION OF LOANS.  Borrower may convert any Borrowing
        from one Type of Borrowing to the other Type; PROVIDED, HOWEVER, that
        any conversion of a Borrowing consisting of LIBOR Loans into a Borrowing
        consisting of Base Rate Loans shall be made on, and only on, the last
        day of an Interest Period for such LIBOR Loans.  Borrower shall request
        such a conversion by an irrevocable written notice to Agent in the form
        of EXHIBIT B, appropriately completed (a "NOTICE OF CONVERSION"), which
        specifies, among other things:

                        (i)     The Borrowing which is to be converted;

                        (ii)    The Type of Borrowing into which such Borrowing
                is to be converted;

                        (iii)   If such Borrowing is to be converted into a
                Borrowing consisting of LIBOR Loans, the initial Interest Period
                selected by Borrower for such Loans in accordance with
                SUBPARAGRAPH 2.01(e); and

                        (iv)    The date of the requested conversion, which
                shall be a Business Day.

        Borrower shall give each Notice of Conversion to Agent at least three
        (3) Business Days before the date of the requested conversion in the
        case of a conversion into a Borrowing consisting of LIBOR Loans with
        Interest Periods of one month or more and on or before the date of the
        requested conversion in the case of a conversion into any other
        Borrowing.


                                       23

<PAGE>

        Each Notice of Conversion shall be delivered by first-class mail or
        facsimile to Agent at the office or to the facsimile number and during
        the hours specified in PARAGRAPH 8.01; PROVIDED, HOWEVER, that Borrower
        shall promptly deliver to Agent the original of any Notice of Conversion
        initially delivered by facsimile.  Agent shall promptly notify each
        Lender of the contents of each Notice of Conversion.

                (e) LIBOR LOAN INTEREST PERIODS.

                        (i)     The initial and each subsequent Interest Period
                selected by Borrower for a LIBOR Loan shall be one (1) week, two
                (2) weeks, one (1) month, two (2) months, three (3) months or
                six (6) months; PROVIDED, HOWEVER, that (A) any Interest Period
                which would otherwise end on a day which is not a Business Day
                shall be extended to the next succeeding Business Day unless
                such next Business Day falls in another calendar month, in which
                case such Interest Period shall end on the immediately preceding
                Business Day; (B) any Interest Period (other than a one-week or
                two-week Interest Period) which begins on the last Business Day
                of a calendar month (or on a day for which there is no
                numerically corresponding day in the calendar month at the end
                of such Interest Period) shall end on the last Business Day of a
                calendar month; and (C) no such Interest Period shall end after
                the Maturity Date.

                        (ii)    Borrower shall notify Agent by an irrevocable
                written notice in the form of EXHIBIT C, appropriately completed
                (a "NOTICE OF INTEREST PERIOD SELECTION"), at least three (3)
                Business Days prior to the last day of each Interest Period for
                LIBOR Loans of the Interest Period selected by Borrower for the
                next succeeding Interest Period for such Loans.  Each Notice of
                Interest Period Selection shall be given by first-class mail or
                facsimile to the office or the facsimile number and during the
                hours specified in PARAGRAPH 8.01; PROVIDED, HOWEVER, that
                Borrower shall promptly deliver to Agent the original of any
                Notice of Interest Period Selection initially delivered by
                facsimile.  If Borrower fails to notify Agent of the next
                Interest Period for LIBOR Loans in accordance with this
                SUBPARAGRAPH 2.01(e), such Loans shall automatically convert to
                Base Rate Loans on the last day of the current Interest Period
                therefor.

                (f) SCHEDULED LOAN PAYMENTS.  Borrower shall repay the principal
        amount of the Loans on the Maturity Date.  Borrower shall pay accrued
        interest on the unpaid principal amount of each Loan in arrears (A) in
        the case of a Base Rate Loan, on the last day in each March, June,
        September and December, (B) in the case of a LIBOR Loan, on the last day
        of each Interest Period therefor (and, if any such Interest Period is
        longer than three (3) months, every three (3) months); and (C) in the
        case of all Loans, upon prepayment (to the extent thereof) and at
        maturity.

                (g) PURPOSE.  Borrower shall use the proceeds of the Loans (i)
        first, to repay on the Closing Date all indebtedness outstanding under
        the Existing Credit Agreement and


                                       24

<PAGE>

        (ii) thereafter, for Borrower's general corporate needs, including the
        consummation of acquisitions otherwise permitted pursuant to the terms
        of this Agreement.

                (h) MATURITY DATE EXTENSIONS.  On or before the last Business
        Day of each December beginning on December 31, 2001, Borrower may
        request the Lenders to extend the Maturity Date for an additional
        one-year period.  Borrower shall request each such extension by
        appropriately completing, executing and delivering to Agent a written
        request in the form of EXHIBIT D (a " MATURITY DATE EXTENSION REQUEST").
        Borrower understands that this SUBPARAGRAPH 2.01(h) is included in this
        Agreement for Borrower's convenience in requesting extensions and
        acknowledges that neither Agent nor any Lender has promised (either
        expressly or by implication), and neither Agent nor any Lender has
        any obligation or commitment, to extend the Maturity Date at any
        time.  Agent shall promptly deliver to each Lender three (3) copies
        of each Maturity Date Extension Request received by Agent.  If a
        Lender, in its sole and absolute discretion, consents to any Maturity
        Date Extension Request, such Lender shall evidence such consent by
        executing and returning two (2) copies of the Maturity Date Extension
        Request to Agent not later than the last Business Day which is thirty
        (30) days after the date Borrower delivered to Agent the Maturity
        Date Extension Request.  Any failure by any Lender to execute and
        return a Maturity Date Extension Request shall be deemed a denial
        thereof.  If Borrower shall deliver a Maturity Date Extension Request
        to Agent pursuant to the first sentence of this SUBPARAGRAPH 2.01(h),
        then not later than the last Business Day which is thirty-five (35)
        days after the date Borrower delivered to Agent the Maturity Date
        Extension Request, Agent shall notify Borrower in writing whether (i)
        Agent has received a copy of the Maturity Date Extension Request
        executed by each Lender, in which case the definition of " Maturity
        Date" set forth in PARAGRAPH 1.01 shall be deemed amended as provided
        in the Maturity Date Extension Request as of the date of such written
        notice from Agent to Borrower, or (ii) Agent has not received a copy
        of the Maturity Date Extension Request executed by each Lender, in
        which case such Maturity Date Extension Request shall be deemed
        denied.  Agent shall deliver to Borrower, with each written notice
        under CLAUSE (i) of the preceding sentence which notifies Borrower
        that Agent has received a Maturity Date Extension Request executed by
        each Lender, a copy of the Maturity Date Extension Request so
        executed by each Lender.

        2.02.   COMMITMENT REDUCTIONS, ETC.

                (a) OPTIONAL REDUCTION OR CANCELLATION OF COMMITMENTS.  Borrower
        may, upon three (3) Business Days written notice to Agent, permanently
        reduce the Total Commitment by the amount of one million Dollars
        ($1,000,000) or an integral multiple of one million Dollars ($1,000,000)
        in excess thereof or cancel the Total Commitment in its entirety;
        PROVIDED, HOWEVER, that:

                        (i)     Borrower may not reduce the Total Commitment
                prior to the Maturity Date, if, after giving effect to such
                reduction, the aggregate principal amount of all Loans then
                outstanding would exceed the Total Commitment; and


                                       25

<PAGE>

                        (ii)    Borrower may not cancel the Total Commitment
                prior to the Maturity Date, if, after giving effect to such
                cancellation, any Loans would then remain outstanding.

                (b) MANDATORY REDUCTION OR CANCELLATION OF COMMITMENTS.  If, at
        any time, Borrower is required to make any mandatory prepayment of Loans
        pursuant to CLAUSE (ii) OF SUBPARAGRAPH 2.04(c), the Total Commitment
        shall be automatically and permanently reduced or cancelled by an amount
        equal to the full amount of any required prepayment.

                (c) EFFECT OF COMMITMENT REDUCTIONS.  From the effective date of
        any reduction of the Total Commitment, the Commitment Fees payable
        pursuant to SUBPARAGRAPH 2.03(b) shall be computed on the basis of the
        Total Commitment as so reduced.  Once reduced or cancelled, the Total
        Commitment may not be increased or reinstated without the prior written
        consent of all Lenders.  Any reduction of the Total Commitment pursuant
        to SUBPARAGRAPH 2.02(a) or SUBPARAGRAPH 2.02(b) shall be applied ratably
        to reduce each Lender's Commitment in accordance with CLAUSE (i) OF
        SUBPARAGRAPH 2.08(a).

        2.03.   FEES.

                (a) AGENT'S FEE.  Borrower shall pay to Agent, for its own
        account, agent's fees and other compensation in the amounts and at the
        times set forth in the Agent's Fee Letter.

                (b) COMMITMENT FEES.  Borrower shall pay to Agent, for the
        ratable benefit of the Lenders as provided in CLAUSE (iii) OF
        SUBPARAGRAPH 2.08(a), nonrefundable commitment fees (the "COMMITMENT
        FEES") equal to the Commitment Fee Percentage on the daily average
        Unused Commitment for the period beginning on the date of this Agreement
        and ending on the Maturity Date.  The Commitment Fee Percentage shall be
        determined as provided in the Pricing Grid and may change for each
        calendar quarter.  Borrower shall pay the Commitment Fees in arrears on
        the last day in each March, June, September and December and on the
        Maturity Date (or if the Total Commitment is cancelled on a date prior
        to the Maturity Date, on such prior date).

                (c) PARTICIPATION FEE.  On the Closing Date, Borrower shall pay
        to Agent, for the benefit of the Lenders, a one-time non-refundable
        participation fee equal to 0.15% of the Total Commitment to be shared
        among the Lenders pro rata in accordance with such Lenders' respective
        proportionate share of the Total Commitment.

        2.04.   PREPAYMENTS.

                (a) TERMS OF ALL PREPAYMENTS.  Upon the prepayment of any Loan
        (whether such prepayment is an optional prepayment under SUBPARAGRAPH
        2.04(b), a mandatory prepayment required by SUBPARAGRAPH 2.04(c) or a
        mandatory prepayment required by any other provision of this Agreement
        or the other Credit Documents, including, without limitation, a
        prepayment upon acceleration), Borrower shall pay to the Lender which
        made such Loan (i) all accrued interest to the date of such prepayment
        on the amount


                                       26

<PAGE>

        prepaid and (ii) if such prepayment is the prepayment of a LIBOR Loan
        on a day other than the last day of an Interest Period for such LIBOR
        Loan, all amounts payable to such Lender pursuant to PARAGRAPH 2.11.

                (b) OPTIONAL PREPAYMENTS.  At its option, Borrower may, upon
        three (3) Business Days notice to Agent, prepay the Loans in any
        Borrowing in part, in an aggregate principal amount of $1,000,000 or
        more, or in whole; except that Borrower may prepay the Loans in any
        Borrowing consisting of Base Rate Loans on the last Business Day in any
        fiscal quarter of Borrower upon same day notice to Agent if Borrower
        delivers such notice to Agent not later than 1:00 p.m. on the date of
        such prepayment.

                (c) MANDATORY PREPAYMENTS.  Borrower shall immediately repay
        Loans as follows:

                        (i)     If, at any time, the aggregate principal amount
                of all Loans then outstanding exceeds the Total Commitment at
                such time, Borrower shall immediately prepay Loans in an
                aggregate principal amount equal to such excess; and

                        (ii)    Upon the incurrence by Borrower of unsecured
                Indebtedness of the type permitted pursuant to CLAUSE (xi) OF
                SUBPARAGRAPH 5.02(a), Borrower shall immediately prepay Loans in
                an amount equal to the Net Proceeds derived from the
                Indebtedness so incurred.

        2.05.   OTHER PAYMENT TERMS.

                (a) PLACE AND MANNER.  Borrower shall make all payments due to
        each Lender or Agent hereunder by payments to Agent at Agent's office
        located at the address specified in PARAGRAPH 8.01, with each payment
        due to a Lender to be for the account of such Lender and such Lender's
        Applicable Lending Office.  Borrower shall make all payments hereunder
        in lawful money of the United States and in same day or immediately
        available funds not later than 12:00 noon on the date due, except that
        Borrower may make prepayments of the Loans in a Borrowing consisting of
        Base Rate Loans on the last Business Day of a fiscal quarter as late as
        1:00 p.m.  Agent shall promptly disburse to each Lender each payment
        received by Agent for the account of such Lender.

                (b) DATE.  Whenever any payment due hereunder shall fall due on
        a day other than a Business Day, such payment shall be made on the next
        succeeding Business Day, and such extension of time shall be included in
        the computation of interest or fees, as the case may be.

                (c) LATE PAYMENTS.  If any amounts required to be paid by
        Borrower under this Agreement or the other Credit Documents (including,
        without limitation, principal or interest payable on any Loan, any fees
        or other amounts) remain unpaid after such amounts are due, Borrower
        shall pay interest on the aggregate, outstanding balance of such amounts
        from the date due until those amounts are paid in full at a per annum
        rate


                                       27

<PAGE>

        equal to the Base Rate PLUS two percent (2.00%), such rate to change
        from time to time as the Base Rate shall change.

                (d) APPLICATION OF PAYMENTS.  All payments hereunder shall be
        applied first to unpaid fees, costs and expenses then due and payable
        under this Agreement or the other Credit Documents, second to accrued
        interest then due and payable under this Agreement or the other Credit
        Documents and finally to reduce the principal amount of outstanding
        Loans.

                (e) FAILURE TO PAY AGENT.  Unless Agent shall have received
        notice from Borrower at least one (1) Business Day prior to the date on
        which any payment is due to the Lenders hereunder that Borrower will not
        make such payment in full, Agent shall be entitled to assume that
        Borrower has made or will make such payment in full to Agent on such
        date and Agent may, in reliance upon such assumption, cause to be paid
        to the Lenders on such due date an amount equal to the amount then due
        such Lenders.  If and to the extent Borrower shall not have so made such
        payment in full to Agent, each such Lender shall repay to Agent
        forthwith on demand such amount distributed to such Lender together with
        interest thereon, for each day from the date such amount is distributed
        to such Lender until the date such Lender repays such amount to Agent,
        at (i) the Federal Funds Rate for the first three (3) days and (ii) the
        per annum rate applicable to Base Rate Loans thereafter.  A certificate
        of Agent submitted to any Lender with respect to any amounts owing by
        such Lender under this SUBPARAGRAPH 2.05(e) shall be conclusive absent
        manifest error.

        2.06.   NOTES AND INTEREST ACCOUNT.

                (a)  NOTES.  The obligation of Borrower to repay the Loans made
        by each Lender and to pay interest thereon at the rates provided herein
        shall be evidenced by a promissory note in the form of EXHIBIT E
        (individually, an "AMENDED AND RESTATED NOTE") which note shall be
        (i) payable to the order of such Lender, (ii) in the amount of such
        Lender's Commitment, (iii) dated the Closing Date and (iv) otherwise
        appropriately completed.  Borrower authorizes each Lender to record on
        the schedule annexed to such Lender's Amended and Restated Note the date
        and amount of each Loan made by such Lender and of each payment or
        prepayment of principal thereon made by Borrower, and agrees that all
        such notations shall constitute prima facie evidence of the matters
        noted; PROVIDED, HOWEVER, that any failure by a Lender to make any such
        notation shall not affect the Obligations.  Borrower further authorizes
        each Lender to attach to and make a part of such Lender's Amended and
        Restated Note continuations of the schedule attached thereto as
        necessary.

                (b)  INTEREST ACCOUNT.  Borrower authorizes Agent to record in
        an account or accounts maintained by Agent on its books (the "INTEREST
        ACCOUNT") (i) the interest rates applicable to all Loans and the
        effective dates of all changes thereto, (ii) the Interest Period for
        each LIBOR Loan, (iii) the date and amount of each principal and
        interest


                                       28

<PAGE>

        payment on each Loan and (iv) such other information as Agent may
        determine is necessary for the computation of interest payable by
        Borrower hereunder.

        2.07.   LOAN FUNDING.

                (a)  LENDER FUNDING AND DISBURSEMENT TO BORROWER.  Each Lender
        shall, before 12:00 noon on the date of each Borrowing, make available
        to Agent at Agent's office specified in PARAGRAPH 8.01, in same day or
        immediately available funds, such Lender's Proportionate Share of such
        Borrowing.  After Agent's receipt of such funds and upon satisfaction of
        the applicable conditions set forth in SECTION III, Agent shall promptly
        disburse such funds to Borrower in same day or immediately available
        funds.  Unless otherwise directed by Borrower, Agent shall disburse the
        proceeds of each Borrowing by disbursement to the account or accounts
        specified in the applicable Notice of Borrowing.

                (b)  LENDER FAILURE TO FUND.  Unless Agent shall have received
        notice from a Lender prior to the date of any Borrowing that such Lender
        will not make available to Agent such Lender's Proportionate Share of
        such Borrowing, Agent shall be entitled to assume that such Lender has
        made or will make such portion available to Agent on the date of such
        Borrowing in accordance with SUBPARAGRAPH 2.07(a), and Agent may on such
        date, in reliance upon such assumption, disburse or otherwise credit to
        Borrower a corresponding amount.  If any Lender does not make the amount
        of its Proportionate Share of any Borrowing available to Agent on or
        prior to the date of such Borrowing, such Lender shall pay to Agent, on
        demand, interest which shall accrue on such amount from the date of such
        Borrowing until such amount is paid to Agent at rates equal to (i) the
        daily Federal Funds Rate during the period from the date of such
        Borrowing through the third Business Day thereafter and (ii) the rate
        applicable to Base Rate Loans thereafter.  A certificate of Agent
        submitted to any Lender with respect to any amounts owing under this
        SUBPARAGRAPH 2.07(b) shall be conclusive absent manifest error.  If the
        amount of any Lender's Proportionate Share of any Borrowing is not paid
        to Agent by such Lender within three (3) Business Days after the date of
        such Borrowing, Borrower shall repay such amount to Agent, on demand,
        together with interest thereon, for each day from the date such amount
        was disbursed to Borrower until the date such amount is repaid to Agent,
        at the interest rate applicable at the time to the Loans comprising such
        Borrowing.

                (c)  LENDERS' OBLIGATIONS SEVERAL.  The failure of any Lender to
        make the Loan to be made by it as part of any Borrowing shall not
        relieve any other Lender of its obligation hereunder to make its Loan on
        the date of such Borrowing, but no Lender shall be obligated in any way
        to make any Loan which another Lender has failed or refused to make or
        otherwise be in any way responsible for the failure or refusal of any
        other Lender to make any Loan required to be made by such other Lender
        on the date of any Borrowing.

        2.08.   PRO RATA TREATMENT.

                (a)     BORROWINGS, COMMITMENT REDUCTIONS, ETC.  Except as
        otherwise provided herein:

                        (i)     Each Borrowing and reduction of the Total
                Commitment shall be made or shared among the Lenders pro rata
                according to their respective Proportionate Shares;

                        (ii)    Each payment of principal of Loans in any
                Borrowing shall be shared among the Lenders which made or funded
                the Loans in such Borrowing pro rata according to the respective
                unpaid principal amounts of such Loans so made or funded by such
                Lenders;

                        (iii)   Each payment of interest on Loans in any
                Borrowing shall be shared among the Lenders which made or funded
                the Loans in such Borrowing pro rata according to (A) the
                respective unpaid principal amounts of such Loans so made or
                funded by such Lenders and (B) the dates on which such Lenders
                so made or funded such Loans;

                        (iv)    Each payment of Commitment Fees shall be shared
                among the Lenders pro rata according to (A) their respective
                Proportionate Shares and (B) in the case of each Lender which
                becomes a Lender hereunder after the date hereof, the date upon
                which such Lender so became a Lender;

                        (v)     Each payment of interest (other than interest on
                Loans) shall be shared among the Lenders and Agent owed the
                amount upon which such interest accrues pro rata according to
                (A) the respective amounts so owed such Lenders and Agent and
                (B) the dates on which such amounts became owing to such Lenders
                and Agent; and

                        (vi)    All other payments under this Agreement and the
                other Credit Documents shall be for the benefit of the Person or
                Persons specified.

                (b)  SHARING OF PAYMENTS, ETC.  If any Lender shall obtain any
        payment (whether voluntary, involuntary, through the exercise of any
        right of setoff, or otherwise) on account of Loans owed to it in excess
        of its ratable share of payments on account of such Loans obtained by
        all Lenders entitled to such payments, such Lender shall forthwith
        purchase from the other Lenders such participations in the Loans as
        shall be necessary to cause such purchasing Lender to share the excess
        payment ratably with each of them; PROVIDED, HOWEVER, that if all or any
        portion of such excess payment is thereafter recovered from such
        purchasing Lender, such purchase shall be rescinded and each other
        Lender shall repay to the purchasing Lender the purchase price to the
        extent of such recovery together with an amount equal to such other
        Lender's ratable share (according to the proportion of (i) the amount of
        such other Lender's required repayment to (ii) the total amount so
        recovered from the purchasing Lender) of any interest or other amount
        paid or


                                       30

<PAGE>

        payable by the purchasing Lender in respect of the total amount so
        recovered.  Borrower agrees that any Lender so purchasing a
        participation from another Lender pursuant to this SUBPARAGRAPH 2.08(b)
        may, to the fullest extent permitted by law, exercise all its rights of
        payment (including the right of setoff) with respect to such
        participation as fully as if such Lender were the direct creditor of
        Borrower in the amount of such participation.

        2.09.   CHANGE OF CIRCUMSTANCES.

                (a)  INABILITY TO DETERMINE RATES.  If, on or before the first
        day of any Interest Period for any LIBOR Loan, (i) any Lender shall
        advise Agent that the LIBO Rate for such Interest Period cannot be
        adequately and reasonably determined due to the unavailability of funds
        in or other circumstances affecting the London interbank market or
        (ii) any Lender shall advise Agent that the rate of interest for such
        Loan does not adequately and fairly reflect the cost to such Lender of
        making or maintaining such LIBOR Loan, Agent shall immediately give
        notice of such condition to Borrower and the other Lenders.  After the
        giving of any such notice and until Agent shall otherwise notify
        Borrower that the circumstances giving rise to such condition no longer
        exist, Borrower's right to request the making of or conversion to, and
        the Lenders' obligations to make or convert to LIBOR Loans shall be
        suspended.  Any LIBOR Loans outstanding at the commencement of any such
        suspension shall be converted at the end of the then current Interest
        Period for such LIBOR Loans into a Base Rate Loans unless such
        suspension has then ended.

                (b)  ILLEGALITY.  If, after the date of this Agreement, the
        adoption of any Governmental Rule, any change in any Governmental Rule
        or the application or requirements thereof (whether such change occurs
        in accordance with the terms of such Governmental Rule as enacted, as a
        result of amendment or otherwise), any change in the interpretation or
        administration of any Governmental Rule by any Governmental Authority,
        or compliance by any Lender with any request or directive (whether or
        not having the force of law) of any Governmental Authority (a "CHANGE OF
        LAW") shall make it unlawful or impossible for any Lender to make or
        maintain any LIBOR Loan, such Lender shall immediately notify Agent and
        Borrower of such Change of Law.  Upon receipt of such notice,
        (i) Borrower's right to request the making of or conversion to, and such
        Lender's obligation to make or convert to LIBOR Loans shall be
        terminated, and (ii) Borrower shall, at the request of such Lender,
        either (A) pursuant to SUBPARAGRAPH 2.01(d) convert any such then
        outstanding LIBOR Loans into Base Rate Loans at the end of the current
        Interest Period for such LIBOR Loans or (B) immediately repay or convert
        any such LIBOR Loans if such Lender shall notify Borrower that such
        Lender may not lawfully continue to fund and maintain such LIBOR Loans.
        Any conversion or prepayment of LIBOR Loans made pursuant to the
        preceding sentence prior to the last day of an Interest Period for such
        LIBOR Loans shall be deemed a prepayment thereof for purposes of
        PARAGRAPH 2.11.  After any Lender notifies Agent and Borrower of such a
        Change of Law and until such Lender notifies Agent and Borrower that it
        is no longer unlawful or impossible for such Lender to make or maintain
        a LIBOR Loan, all Loans of such Lender shall be Base Rate Loans.


                                       31

<PAGE>


                (c)  INCREASED COSTS.  If, after the date of this Agreement,
        any Change of Law:

                        (i)     Shall subject any Lender to any tax, duty or
                other charge with respect to any LIBOR Loan, or shall change the
                basis of taxation of payments by Borrower to any Lender on such
                a LIBOR Loan or in respect to such a LIBOR Loan under this
                Agreement (except for changes in the rate of taxation on the
                overall net income of any Lender imposed by its jurisdiction of
                incorporation or the jurisdiction in which its principal
                executive office is located); or

                        (ii)    Shall impose, modify or hold applicable any
                reserve (excluding any Reserve Requirement or other reserve to
                the extent included in the calculation of the LIBO Rate for any
                Loans), special deposit or similar requirement against assets
                held by, deposits or other liabilities in or for the account of,
                advances or loans by, or any other acquisition of funds by any
                Lender for any LIBOR Loan; or

                        (iii)   Shall impose on any Lender any other condition
                related to any LIBOR Loan or such Lender's Commitment;

        And the effect of any of the foregoing is to increase the cost to such
        Lender of making, renewing, or maintaining any such LIBOR Loan or its
        Commitment or to reduce any amount receivable by such Lender hereunder;
        then Borrower shall from time to time, within five (5) days after demand
        by such Lender, pay to such Lender additional amounts sufficient to
        reimburse such Lender for such increased costs or to compensate such
        Lender for such reduced amounts.  A certificate as to the amount of such
        increased costs or reduced amounts, submitted by such Lender to Borrower
        shall, in the absence of manifest error, be conclusive and binding on
        Borrower for all purposes.  The obligations of Borrower under this
        SUBPARAGRAPH 2.09(c) shall survive the payment and performance of the
        Obligations and the termination of this Agreement.

                (d)  CAPITAL REQUIREMENTS.  If, after the date of this
        Agreement, any Lender determines that (i) any Change of Law affects the
        amount of capital required or expected to be maintained by such Lender
        or any Person controlling such Lender (a "CAPITAL ADEQUACY REQUIREMENT")
        and (ii) the amount of capital maintained by such Lender or such Person
        which is attributable to or based upon the Loans, the Commitments or
        this Agreement must be increased as a result of such Capital Adequacy
        Requirement (taking into account such Lender's or such Person's policies
        with respect to capital adequacy), Borrower shall pay to such Lender or
        such Person, within five (5) days after demand of such Lender, such
        amounts as such Lender or such Person shall determine are necessary to
        compensate such Lender or such Person for the increased costs to such
        Lender or such Person of such increased capital.  A certificate of any
        Lender setting forth in reasonable detail the computation of any such
        increased costs, delivered by such Lender to Borrower shall, in the
        absence of manifest error, be conclusive and binding on Borrower for all
        purposes.  The obligations of Borrower under this SUBPARAGRAPH 2.09(d)
        shall survive the payment and performance of the Obligations and the
        termination of this Agreement.

                                          32

<PAGE>

                (e)  MITIGATION.  Any Lender which becomes aware of (i) any
        Change of Law which will make it unlawful or impossible for such Lender
        to make or maintain any LIBOR Loan or (ii) any Change of Law or other
        event or condition which will obligate Borrower to pay any amount
        pursuant to SUBPARAGRAPH 2.09(c) or SUBPARAGRAPH 2.09(d) shall notify
        Borrower and Agent thereof as promptly as practical.  If any Lender has
        given notice of any such Change of Law or other event or condition and
        thereafter becomes aware that such Change of Law or other event or
        condition has ceased to exist, such Lender shall notify Borrower and
        Agent thereof as promptly as practical.  Each Lender affected by any
        Change of Law which makes it unlawful or impossible for such Lender to
        make or maintain any LIBOR Loan or to which Borrower is obligated to pay
        any amount pursuant to SUBPARAGRAPH 2.09(c) or SUBPARAGRAPH 2.09(d)
        shall use reasonable commercial efforts (including changing the
        jurisdiction of its Applicable Lending Office) to avoid the effect of
        such Change of Law or to avoid or materially reduce any amounts which
        Borrower is obligated to pay pursuant to SUBPARAGRAPH 2.09(c) or
        SUBPARAGRAPH 2.09(d) if, in the reasonable opinion of such Lender, such
        efforts would not be disadvantageous to such Lender or contrary to such
        Lender's normal banking practices.

     2.10.      TAXES ON PAYMENTS.

                (a)  PAYMENTS FREE OF TAXES.  All payments made by Borrower
        under this Agreement and the other Credit Documents shall be made free
        and clear of, and without deduction or withholding for or on account of,
        any present or future income, stamp or other taxes, levies, imposts,
        duties, charges, fees, deductions or withholdings, now or hereafter
        imposed, levied, collected, withheld or assessed by any Governmental
        Authority (except net income taxes and franchise taxes in lieu of net
        income taxes imposed on Agent or any Lender by its jurisdiction of
        incorporation or the jurisdiction in which its Applicable Lending Office
        is located) (all such non-excluded taxes, levies, imposts, duties,
        charges, fees, deductions and withholdings being hereinafter called
        "TAXES").  If any Taxes are required to be withheld from any amounts
        payable to Agent or any Lender hereunder or under the other Credit
        Documents, the amounts so payable to Agent or such Lender shall be
        increased to the extent necessary to yield to Agent or such Lender
        (after payment of all Taxes) interest or any such other amounts payable
        hereunder at the rates or in the amounts specified in this Agreement and
        the other Credit Documents.  Whenever any Taxes are payable by Borrower,
        as promptly as possible thereafter, Borrower shall send to Agent for its
        own account or for the account of such Lender, as the case may be, a
        certified copy of an original official receipt received by Borrower
        showing payment thereof.  If Borrower fails to pay any Taxes when due to
        the appropriate taxing authority or fails to remit to Agent the required
        receipts or other required documentary evidence, Borrower shall
        indemnify Agent and the Lenders for any incremental taxes, interest or
        penalties that may become payable by Agent or any Lender as a result of
        any such failure.  The obligations of Borrower under this
        SUBPARAGRAPH 2.10(a) shall survive the payment and performance of the
        Obligations and the termination of this Agreement.

                (b)  WITHHOLDING EXEMPTION CERTIFICATES.  On or prior to the
        date of the initial Borrowing or, if such date does not occur within
        thirty (30) days after the date of this Agreement, by the end of such
        30-day period, each Lender which is not organized under the laws of the
        United States of America or a state thereof shall deliver to Borrower
        and Agent two duly completed copies of United States Internal Revenue
        Service Form 1001 or 4224 (or successor applicable form), as the case
        may be, certifying in each case that such Lender is entitled to receive
        payments under this Agreement without deduction or withholding of any
        United States federal income taxes.  Each Lender which delivers to
        Borrower and Agent a Form 1001 or 4224 pursuant to the immediately
        preceding sentence further undertakes to deliver to Borrower and Agent
        two further copies of Form 1001 or 4224 (or successor applicable forms),
        as the case may be, on or before the date that any such form expires or
        becomes obsolete or after the occurrence of any event requiring a change
        in the most recent form previously delivered by such Lender to Borrower
        and Agent, certifying that such Lender is entitled to receive payments
        under this Agreement without deduction or withholding of any United
        States federal income taxes.  Each Lender which is not organized under
        the laws of the United States of America or a state thereof further
        agrees (i) promptly to notify Agent and Borrower of any change of
        circumstances (including without limitation any change in any treaty,
        law or regulation) which would prevent such Lender from receiving
        payments hereunder without any deduction or withholding of United States
        federal income tax and (ii) to furnish to Agent and Borrower any other
        manner of certification as Agent or Borrower may reasonably request to
        establish the right of such Lender to receive payments hereunder without
        any deduction or withholding of United States federal income tax.

                (c)  MITIGATION.  If Agent or any Lender claims any additional
        amounts to be payable to it pursuant to this PARAGRAPH 2.10, such Person
        shall use reasonable commercial efforts to file any certificate or
        document requested in writing by Borrower (including without limitation
        copies of Internal Revenue Service Form 1001 (or successor forms)
        reflecting a reduced rate of withholding) or to change the jurisdiction
        of its Applicable Lending Office if the making of such a filing or such
        change in the jurisdiction of its Applicable Lending Office would avoid
        the need for or materially reduce the amount of any such additional
        amounts which may thereafter accrue and if, in the reasonable opinion of
        such Person, in the case of a change in the jurisdiction of its
        Applicable Lending Office, such change would not be disadvantageous to
        such Person or contrary to such Person's normal banking practices.

                (d)  TAX RETURNS.  Nothing contained in this PARAGRAPH 2.10
        shall require Agent or any Lender to make available any of its tax
        returns (or any other information relating to its taxes which it deems
        to be confidential).

        2.11.   FUNDING LOSS INDEMNIFICATION.  If borrower shall (a) repay,
prepay or convert any LIBOR loan on any day other than the last day of an
interest period therefor (whether a scheduled payment, an optional prepayment
or conversion, a mandatory prepayment or conversion, a payment upon
acceleration or otherwise), (b) fail to borrow any LIBOR loan for which a
Notice of Borrowing has been delivered to Agent (whether as a result of the
failure to

                                      34

<PAGE>

satisfy any applicable conditions or otherwise) or (c) fail to convert any
loans into LIBOR loans in accordance with a Notice of Conversion delivered to
Agent (whether as a result of the failure to satisfy any applicable
conditions or otherwise), Borrower shall, upon demand by any Lender,
reimburse such Lender for and hold such Lender harmless from all costs and
losses incurred by such Lender as a result of such repayment, prepayment,
conversion or failure.  Borrower understands that such costs and losses may
include, without limitation, losses incurred by a Lender as a result of
funding and other contracts entered into by such Lender to fund a LIBOR loan.
 Each lender demanding payment under this PARAGRAPH 2.11 shall deliver to
Borrower, with a copy to Agent, a certificate setting forth the amount of
costs and losses for which demand is made, which certificate shall set forth
in reasonable detail the calculation of the amount demanded.  Such a
certificate so delivered to Borrower shall constitute PRIMA FACIE evidence of
such costs and losses.  The obligations of Borrower under this PARAGRAPH 2.11
shall survive the payment and performance of the Obligations and the
termination of this Agreement.

        2.12.    SECURITY.

             (a)  GUARANTIES.  The Secured Obligations shall be  Guaranteed
        by an Amended and Restated Guaranty in the form of EXHIBIT F, duly
        executed by each Domestic Subsidiary of Borrower (the "AMENDED AND
        RESTATED GUARANTY").

             (b)  mortgages, security agreements, etc.  on and after the
        first amendment effective date, the secured obligations shall be secured
        by the following:

                     (i)     a security agreement in the form of exhibit H-1,
                duly executed by borrower (the "borrower security agreement");

                        (ii)    a domestic subsidiary security agreement in the
                form of exhibit H-2, duly executed by each domestic subsidiary
                of borrower (each a "domestic subsidiary security agreement,"
                and collectively, the "domestic subsidiary security
                agreements");

                     (iii)   a borrower intellectual property security
                agreement in the form of exhibit I-1, duly executed by borrower
                (the "borrower ip security agreement");

                     (iv)    a domestic subsidiary intellectual property
                security agreement in the form of exhibit i-2, duly executed by
                each domestic subsidiary of borrower (each a "domestic
                subsidiary ip security agreement," and collectively, the
                "domestic subsidiary ip security agreements"); and

                     (v)     a pledge agreement in the form of exhibit J,
                duly executed by borrower (the "pledge agreement").
                                      35

<PAGE>

                (c)  FURTHER ASSURANCES.  Except as otherwise provided in
        Subparagraph 2.12(e), Borrower shall deliver, or cause its Subsidiaries
        to deliver, to Agent such additional mortgages, deeds of trust, security
        agreements, pledge agreements, guaranties, lessor consents and estoppels
        (containing appropriate mortgagee and lender protection language) and
        other instruments, agreements, certificates, opinions and documents
        (including Uniform Commercial Code financing statements and fixture
        filings and landlord waivers) as Required Lenders may reasonably request
        to :

                     (i)     Grant, perfect, maintain, protect and evidence
                security interests in favor of Agent, for the benefit of Agent
                and the Lenders as security for the Secured Obligations, in any
                or all present and future real and personal property of Borrower
                and each Domestic Subsidiary of Borrower prior to the Liens or
                other interests of any Person, except for Permitted Liens;

                        (ii)    Cause all Domestic Subsidiaries of Borrower to
                guarantee the Secured Obligations on the terms set forth in the
                Amended and Restated Guaranty; and

                     (iii)   Otherwise establish, maintain, protect and
                evidence the rights provided to Agent, for the benefit of Agents
                and the Lenders, pursuant to the  Security Documents.

        Borrower shall fully cooperate with Agent and the Lenders and perform
        all additional acts reasonably requested by Agent or any Lender to
        effect the purposes of this PARAGRAPH 2.12.

                (d)  ALLOCATION OF COLLATERAL PROCEEDS.  Agent shall apply any
        proceeds realized by Agent from the sale, disposition or collection of
        Collateral as follows:

                        (i)     Agent first shall apply such proceeds to pay all
                reasonable costs and expenses incurred by Agent in realizing
                such proceeds.

                     (ii)    If any proceeds then remain, Agent shall apply
                such proceeds to the Primary Secured Obligations until all such
                obligations are satisfied in full.  If such proceeds are
                insufficient to satisfy all of the Primary Secured Obligations
                in full, Agent shall allocate such proceeds among the Lenders
                pro rata according to the Primary Secured Obligations then owed
                to each Lender.

                     (iii)   If any proceeds then remain, Agent shall apply
                such proceeds to the Secondary Secured Obligations until all
                such obligations are satisfied in full.  If such proceeds are
                insufficient to satisfy all of the Secondary Secured Obligations
                in full, Agent shall allocate such proceeds among the
                                      36

<PAGE>

                Lenders pro rata according to the Secondary Secured Obligations
                then owed to each Lender.

                (e)  Release of Collateral.

                        (i)     Each Lender hereby authorizes Agent to execute
                and deliver such documents, instruments and agreements as
                borrower may reasonably request to release the Lien granted to
                Agent by the Security Documents in any Collateral that is sold
                by Borrower in accordance with Subparagraph 5.02(c).  In
                determining whether a sale is in accordance with Subparagraph
                5.02(c), Agent may rely upon certificates of Borrower or such
                other evidence as Agent may deem appropriate.

                        (ii)    In addition, if during each of any two
                consecutive fiscal quarters occurring after the First Amendment
                Effective Date Borrower maintains a Debt/EBITDA Ratio of less
                than 1.00 to 1.00 (as determined by agent in its reasonable
                discretion), Agent shall execute and deliver (and each Lender
                hereby authorizes Agent to execute and deliver) such documents,
                instruments and agreements as Borrower may reasonably request to
                release the Lien granted to Agent by the Security Documents in
                the Collateral.

        2.13.   REPLACEMENT OF LENDERS.  IF any Lender shall (a) suspend its
obligation to make or maintain LIBOR Loans pursuant to SUBPARAGRAPH 2.09(b)
for a reason which is not applicable to the Lenders (or a material number of
the Lenders) generally, or (b) demand any payment under SUBPARAGRAPH 2.09(c),
2.09(d) OR 2.10(a) for a reason which is not applicable to the Lenders (or a
material number of the Lenders) generally, then Agent may (or upon the
written request of Borrower so long as no Default or Event of Default shall
have occurred and be continuing, shall) replace such Lender (the "AFFECTED
LENDER"), or cause such affected Lender to be replaced, with another lender
(the "REPLACEMENT LENDER") satisfying the requirements of an Assignee Lender
under SUBPARAGRAPH 8.05(c), by having the affected Lender sell and assign all
of its rights and obligations under this Agreement and the other Credit
Documents to the replacement lender pursuant to SUBPARAGRAPH 8.05(c);
PROVIDED, HOWEVER, that if Borrower seeks to exercise such right, it must do
so within one hundred twenty (120) days after it first knows or should have
known of the occurrence of the event or events giving rise to such right, and
neither Agent nor any Lender shall have any obligation to identify or locate
a replacement lender for Borrower.  Upon receipt by any affected Lender of a
written notice from Agent stating that Agent is exercising the replacement
right set forth in this PARAGRAPH 2.1e, such affected Lender shall sell and
assign all of its rights and obligations under this Agreement and the other
Credit Documents to the replacement lender pursuant to an Assignment
Agreement and SUBPARAGRAPH 8.05(c) for a purchase price equal to the sum of
the principal amount of the affected Lender's Loans so sold and assigned, all
accrued and unpaid interest thereon and its ratable share of all fees to
which it is entitled.

SECTION III.    CONDITIONS PRECEDENT.

        3.01.   INITIAL CONDITIONS PRECEDENT.  The obligations of the Lenders to
make the loans comprising the initial borrowing are subject to receipt by agent,
on or prior to the Closing Date, of each item listed in SCHEDULE 3.01, each in
form and substance satisfactory to Agent and each Lender, and with sufficient
copies for, Agent and each Lender.

        3.02.   CONDITIONS PRECEDENT TO EACH CREDIT EVENT.  The occurrence of
each Credit Event (including the initial borrowing) is subject to the further
conditions that:

                (a)  Borrower shall have delivered to Agent the Notice of
        Borrowing, notice of conversion or notice of interest period selection,
        as the case may be, for such credit event in accordance with this
        agreement; and

                (b)  On the date such credit event is to occur and after giving
        effect to such credit event, the following shall be true and correct:

                        (i)     The representations and warranties of Borrower
                and its Subsidiaries set forth in PARAGRAPH 4.01 and in the
                other Credit Documents are true and correct in all material
                respects as if made on such date (except for representations and
                warranties expressly made as of a specified date, which shall be
                true as of such date);

                        (ii)    No Default or Event of Default has occurred and
                is continuing or will result from such Credit Event; and

                        (iii)   All of the Credit Documents are in full force
                and effect.

        The submission by Borrower to Agent of each Notice of Borrowing, each
        Notice of Conversion (other than a notice for a conversion to a Base
        Rate Loan) and each Notice of Interest Period Selection shall be deemed
        to be a representation and warranty by Borrower that each of the
        statements set forth above in this SUBPARAGRAPH 3.02(b) is true and
        correct as of the date of such notice.

        3.03.   COVENANT TO DELIVER.  Borrower agrees (not as a condition but
as a covenant) to deliver to Agent each item required to be delivered to
Agent as a condition to the occurrence of any Credit Event if such credit
event occurs. Borrower expressly agrees that the occurrence of any such
credit event prior to the receipt by agent of any such item shall not
constitute a waiver by Agent or any Lender of Borrower's obligation to
deliver such item.

SECTION IV.     REPRESENTATIONS AND WARRANTIES.

        4.01.   BORROWER'S REPRESENTATIONS AND WARRANTIES.  In order to
induce Agent and the Lenders to enter into this Agreement, Borrower hereby
represents and warranties to Agent and the Lenders as follows:

                                     38

<PAGE>

                (a)  DUE INCORPORATION, QUALIFICATION, ETC.  Each of Borrower
        and Borrower's Subsidiaries (i) is a corporation duly organized, validly
        existing and in good standing under the laws of its jurisdiction of
        organization; (ii) has the power and authority to own, lease and operate
        its properties and carry on its business as now conducted; and (iii) is
        duly qualified, licensed to do business and in good standing as a
        foreign corporation in each jurisdiction where the failure to be so
        qualified or licensed is reasonably likely to have a Material Adverse
        Effect.

                (b)  AUTHORITY.  The execution, delivery and performance by
        Borrower of each Credit Document executed, or to be executed, by
        Borrower and the consummation of the transactions contemplated thereby
        (i) are within the power of Borrower and (ii) have been duly authorized
        by all necessary actions on the part of Borrower.

                (c)  ENFORCEABILITY.  Each Credit Document executed, or to be
        executed, by Borrower has been, or will be, duly executed and delivered
        by Borrower and constitutes, or will constitute, a legal, valid and
        binding obligation of Borrower, enforceable against Borrower in
        accordance with its terms, except as limited by bankruptcy, insolvency
        or other laws of general application relating to or affecting the
        enforcement of creditors' rights generally and general principles of
        equity.

                (d)  NON-CONTRAVENTION.  The execution and delivery by Borrower
        of the Credit Documents executed by Borrower and the performance and
        consummation of the transactions contemplated thereby do not (i) violate
        any Requirement of Law applicable to Borrower; (ii) violate any
        provision of, or result in the breach or the acceleration of, or entitle
        any other Person to accelerate (whether after the giving of notice or
        lapse of time or both), any Contractual Obligation of Borrower; or
        (iii) result in the creation or imposition of any Lien (or the
        obligation to create or impose any Lien) upon any property, asset or
        revenue of Borrower (except such Liens as may be created in favor of
        Agent pursuant to this Agreement or the other Credit Documents).

                (e)  APPROVALS.  No consent, approval, order or authorization
        of, or registration, declaration or filing with, any Governmental
        Authority or other Person (including, without limitation, the
        shareholders of any Person) is required in connection with the execution
        and delivery of the Credit Documents executed by Borrower and the
        performance and consummation of the transactions contemplated thereby,
        except such as have been made or obtained and are in full force and
        effect.

                (f)  NO VIOLATION OR DEFAULT.  Neither Borrower nor any of its
        Subsidiaries is in violation of or in default with respect to (i) any
        Requirement of Law applicable to such Person; (ii) any Contractual
        Obligation of such Person (nor is there any waiver in effect which, if
        not in effect, would result in such a violation or default), where, in
        each case, such violation or default is reasonably likely to have a
        Material Adverse Effect.  Without limiting the generality of the
        foregoing, neither Borrower nor any of its Subsidiaries (A) has violated
        any Environmental Laws, (B) has any liability under any Environmental
        Laws or (C) has received notice or other communication of an
        investigation or is under

                                     39

<PAGE>

        investigation by any Governmental Authority having authority to enforce
        Environmental Laws, where such violation, liability or investigation is
        reasonably likely to have a Material Adverse Effect.  No Event of
        Default or Default has occurred and is continuing.

                (g)  LITIGATION.  No actions (including, without limitation,
        derivative actions), suits, proceedings or investigations are pending
        or, to the knowledge of Borrower, threatened against Borrower or any of
        its Subsidiaries at law or in equity in any court or before any other
        Governmental Authority which (i) are reasonably likely (alone or in the
        aggregate) to have a Material Adverse Effect or (ii) seek to enjoin,
        either directly or indirectly, the execution, delivery or performance by
        Borrower of the Credit Documents or the transactions contemplated
        thereby.

                (h)  TITLE; POSSESSION UNDER LEASES.  Set forth in Schedule 7 to
        the Collateral Certificate (as supplemented by Borrower from time to
        time in a written notice to Agent pursuant to clause (vii) of
        Subparagraph 5.01(a) or otherwise) is a complete list of all real
        property owned by Borrower or any of its Domestic Subsidiaries, with the
        owner of such property, the location of such property, a brief
        description of such property and the use of such property.  Set forth in
        Schedule 7 to the Collateral Certificate (as supplemented by Borrower
        from time to time in a written notice to Agent pursuant to clause (vii)
        of Subparagraph 5.01(a) or otherwise) is a complete list of all real
        property leased by Borrower or any of its Domestic Subsidiaries as
        lessee or sublessee, with the lessee or sublessee of such property, the
        location of such property, a brief description of such property, the use
        of such property, the owner of such property and the date and title of
        and parties to the lease for such property (including all amendments
        thereof).  Borrower and its Subsidiaries own and have good and
        marketable title, or a valid leasehold interest in, all their respective
        properties and assets as reflected in the most recent Financial
        Statements delivered to Agent (except those assets and properties
        disposed of in the ordinary course of business or otherwise in
        compliance with this Agreement since the date of such Financial
        Statements) and all respective assets and properties acquired by
        Borrower and its Subsidiaries since such date (except those disposed of
        in the ordinary course of business or otherwise in compliance with this
        Agreement).  Such assets and properties are subject to no Lien, except
        for Permitted Liens.  Each of Borrower and its Subsidiaries has complied
        with all obligations under all leases to which it is a party and enjoys
        peaceful and undisturbed possession under such leases except where the
        failure to so comply or enjoy is not reasonably likely to have a
        Material Adverse Effect.

                (i)  FINANCIAL STATEMENTS.  The Financial Statements of Borrower
        and its Subsidiaries which have been delivered to Agent, (i) are in
        accordance with the books and records of Borrower and its Subsidiaries,
        which have been maintained in accordance with good business practice;
        (ii) have been prepared in conformity with GAAP; and (iii) fairly
        present the financial conditions and results of operations of Borrower
        and its Subsidiaries as of the date thereof and for the periods covered
        thereby.  Neither Borrower nor any of its Subsidiaries has any
        Contingent Obligations or other outstanding obligations which are
        material in the aggregate, except as disclosed in the audited Financial
        Statements

                                     40

<PAGE>

        dated September 27, 1998, furnished by Borrower to Agent prior to the
        date hereof, or in the Financial Statements delivered to Agent pursuant
        to CLAUSE (I) OR (II) OF SUBPARAGRAPH 5.01(A).

                (j)  NO AGREEMENTS TO SELL ASSETS; ETC.  Neither Borrower nor
        any of its Subsidiaries has any legal obligation, absolute or
        contingent, to any Person to sell all or substantially all of the assets
        of Borrower or, except to the extent permitted pursuant to SUBPARAGRAPH
        5.02(d) OR 5.02(e), any of its Subsidiaries (other than sales in the
        ordinary course of business), or to effect any merger, consolidation or
        other reorganization of Borrower or, except to the extent permitted
        pursuant to SUBPARAGRAPH 5.02(d) OR 5.02(e), any of its Subsidiaries or
        to enter into any agreement with respect thereto.

                (k)  EMPLOYEE BENEFIT PLANS.

                        (i)     Based on the latest valuation of each Employee
                Benefit Plan that either Borrower or any ERISA Affiliate
                maintains or contributes to, or has any obligation under (which
                occurred within twelve months of the date of this
                representation), the aggregate benefit liabilities of such plan
                within the meaning of Section 4001 of ERISA did not exceed the
                aggregate value of the assets of such plan.  Neither Borrower
                nor any ERISA Affiliate has any liability with respect to any
                post-retirement benefit under any Employee Benefit Plan which is
                a welfare plan (as defined in section 3(1) of ERISA), other than
                liability for health plan continuation coverage described in
                Part 6 of Title I(B) of ERISA, which liability for health plan
                contribution coverage is not reasonably likely to have a
                Material Adverse Effect.

                        (ii)    Each Employee Benefit Plan complies, in both
                form and operation, in all material respects, with its terms,
                ERISA and the IRC, and no condition exists or event has occurred
                with respect to any such plan which would result in the
                incurrence by either Borrower or any ERISA Affiliate of any
                material liability, fine or penalty.  Each Employee Benefit
                Plan, related trust agreement, arrangement and commitment of
                Borrower or any ERISA Affiliate is legally valid and binding and
                in full force and effect.  No Employee Benefit Plan is being
                audited or investigated by any government agency or is subject
                to any pending or threatened claim or suit.  Neither Borrower
                nor any ERISA Affiliate nor any fiduciary of any Employee
                Benefit Plan has engaged in a prohibited transaction under
                section 406 of ERISA or section 4975 of the IRC.

                        (iii)   Neither Borrower nor any ERISA Affiliate
                contributes to or has any material contingent obligations to any
                Multiemployer Plan.  Neither Borrower nor any ERISA Affiliate
                has incurred any material liability (including secondary
                liability) to any Multiemployer Plan as a result of a complete
                or partial withdrawal from such Multiemployer Plan under
                Section 4201 of ERISA or as a result of a sale of assets
                described in Section 4204 of ERISA.  Neither Borrower nor any
                ERISA Affiliate has been notified that any Multiemployer Plan is
                in

                                     41

<PAGE>

                reorganization or insolvent under and within the meaning of
                Section 4241 or Section 4245 of ERISA or that any Multiemployer
                Plan intends to terminate or has been terminated under
                Section 4041A of ERISA.

                (l)  OTHER REGULATIONS.  Borrower is not subject to regulation
        under the Investment Company Act of 1940, the Public Utility Holding
        Company Act of 1935, the Federal Power Act, any state public utilities
        code or to any other Governmental Rule limiting its ability to incur
        indebtedness.

                (m)  PATENT AND OTHER RIGHTS.  Borrower and its Subsidiaries own
        or license (or could obtain such ownership or license on terms not
        materially adverse to Borrower and its Subsidiaries, taken as a whole)
        under validly existing agreements, and have the full right to license in
        the ordinary course of business as currently contemplated without the
        consent of any other Person, all patents, licenses, trademarks, trade
        names, trade secrets, service marks, copyrights and all rights with
        respect thereto, which are required to conduct their businesses as now
        conducted.

                (n)  GOVERNMENTAL CHARGES.  Borrower and its Subsidiaries have
        filed or caused to be filed all tax returns which are required to be
        filed by them.  Borrower and its Subsidiaries have paid, or made
        provision for the payment of, all taxes and other Governmental Charges
        which have or may have become due pursuant to said returns or otherwise
        and all other indebtedness, except such Governmental Charges or
        indebtedness, if any, which are being contested in good faith and as to
        which adequate reserves (determined in accordance with GAAP) have been
        provided or which are not reasonably likely to have a Material Adverse
        Effect if unpaid.

                (o)  MARGIN STOCK.  Borrower owns no Margin Stock which would
        cause it to be in violation of SUBPARAGRAPH 5.01(f).

                (p)  SUBSIDIARIES, ETC.  Set forth in SCHEDULE 4.01(p) (as
        supplemented by Borrower from time to time in a written notice to Agent)
        is a complete list of all of Borrower's Subsidiaries; the jurisdiction
        of incorporation of each such Subsidiary; for each Domestic Subsidiary
        and each direct Foreign Subsidiary, the number of shares of each class
        of Equity Security of such Subsidiary outstanding; and the percentage of
        each such Subsidiary's outstanding Equity Securities owned directly by
        Borrower or another Subsidiary of Borrower.  Except for such
        Subsidiaries, Borrower has no Subsidiaries, is not a partner in any
        partnership or a joint venturer in any joint venture.

                (q)  CATASTROPHIC EVENTS.  Neither Borrower nor any of its
        Subsidiaries and none of their properties is or has been affected by any
        fire, explosion, accident, strike, lockout or other labor dispute,
        drought, storm, hail, earthquake, embargo, act of God or other casualty
        that is reasonably likely to have a Material Adverse Effect.  There are
        no disputes presently subject to grievance procedure, arbitration or
        litigation under any of the collective bargaining agreements, employment
        contracts or employee welfare or incentive plans to which Borrower or
        any of its Subsidiaries is a party, and there are no strikes, lockouts,
        work stoppages or slowdowns, or, to the best knowledge of Borrower,

                                     42

<PAGE>

        jurisdictional disputes or organizing activities occurring or threatened
        which alone or in the aggregate are reasonably likely to have a Material
        Adverse Effect.

                (r)  BURDENSOME CONTRACTUAL OBLIGATIONS, ETC.  Neither Borrower
        nor any of its Subsidiaries and none of their properties is subject to
        any Contractual Obligation or Requirement of Law which is reasonably
        likely to have a Material Adverse Effect.

                (s)  NO MATERIAL ADVERSE EFFECT.  No event has occurred and no
        condition exists which is reasonably likely to have a Material Adverse
        Effect.

                (t)  ACCURACY OF INFORMATION FURNISHED.  None of the Credit
        Documents and none of the other certificates, statements or information
        furnished to Agent or any Lender by or on behalf of Borrower or any of
        its Subsidiaries in connection with the Credit Documents or the
        transactions contemplated thereby contains or will contain any untrue
        statement of a material fact or omits or will omit to state a material
        fact necessary to make the statements therein, in light of the
        circumstances under which they were made, not misleading; PROVIDED,
        HOWEVER, that it is recognized by Agent and the Lenders that projections
        and forecasts provided and developed by Borrower, while reflecting
        Borrower's good faith projections or forecasts based upon methods and
        data Borrower believed to be reasonable and accurate when made, are not
        to be viewed as facts and that actual results during the period or
        periods covered by any such projections and forecasts may differ from
        the projected or forecasted results.

                (u)  YEAR 2000 COMPATIBILITY.  Borrower and its Subsidiaries
        have reviewed the areas within their business and operations which could
        be adversely affected by, and have developed or are developing a program
        to address on a timely basis, the "Year 2000 Problem" (that is, the risk
        that computer applications used by Borrower and its Subsidiaries may be
        unable to recognize and perform properly date-sensitive functions
        involving certain dates prior to and any date on or after December 31,
        1999), and have made related appropriate inquiry of material suppliers
        and vendors.  Based on such review and program, Borrower believes that
        the "Year 2000 Problem" will not have a Material Adverse Effect.

        4.02.   REAFFIRMATION.  Borrower shall be deemed to have reaffirmed,
for the benefit of the Lenders and Agent, each representation and warranty
contained in PARAGRAPH 4.01 and in the other Credit Documents on and as of
the date of each Credit Event (except for representations and warranties
expressly made as of a specified date, which shall be true as of such date).

SECTION V.      COVENANTS.

        5.01.   AFFIRMATIVE COVENANTS.  Until the termination of this
Agreement and the satisfaction in full by Borrower of all Obligations,
Borrower will comply, and will cause compliance, with the following
affirmative covenants, unless Required Lenders shall otherwise consent in
writing:

                (c)  INSPECTIONS.  Borrower and its Subsidiaries shall permit
        any Person designated by any Lender, upon reasonable notice and during
        normal business hours, to visit and inspect any of the properties and
        offices of Borrower and its Subsidiaries, to conduct audits of any or
        all of the Collateral at Borrower's expense, to examine the books and
        records of Borrower and its Subsidiaries and make copies thereof and to
        discuss the affairs, finances and business of Borrower and its
        Subsidiaries with, and to be advised as to the same by, their officers,
        auditors and accountants, all at such times and intervals as any Lender
        may reasonably request; provided, however, that, so long as no Default
        or Event of Default has occurred and is continuing, (i) audits of the
        Collateral shall be conducted by Persons designated by Agent at
        reasonable cost and shall not be conducted at Borrower's expense more
        than once in any twelve (12) month period and (ii) Agent shall use its
        best efforts to schedule such audits at times during which Borrower and
        its Subsidiaries are conducting their own audits in order to minimize
        the expenses incurred by Agent or its designees in performing such
        audits.

                (d)  INSURANCE.  Borrower and its Subsidiaries shall:

                        (i)     Carry and maintain insurance of the types and in
                the amounts customarily carried from time to time during the
                term of this Agreement by others engaged in substantially the
                same business as such Person and operating in the same
                geographic area as such Person, including, but not limited to,
                fire, public liability, property damage and worker's
                compensation;

                        (ii)    Carry and maintain each policy for such
                insurance with (A) a company which is rated A or better by A.M.
                Best and Company at the time such policy is placed and at the
                time of each annual renewal thereof or (B) any other insurer
                which is reasonably satisfactory to Agent;

                        (iii)   Obtain and maintain endorsements for such
                insurance as specified in Exhibit L; and

                        (iv)    Deliver to Agent from time to time, as Agent may

        shall be rendered against Borrower and/or any of its Subsidiaries in
        connection with any single or related series of transactions, incidents
        or circumstances and the same shall not be vacated or stayed for a
        period of ten (10) consecutive days; (ii) any judgment, writ,
        assessment, warrant of attachment, tax lien or execution or similar
        process shall be issued or levied against a substantial part of the
        property of Borrower or any of its Subsidiaries and the same shall not
        be released, stayed, vacated or otherwise dismissed within ten (10) days
        after issue or levy; or (iii) any other judgments, orders, decrees,
        arbitration awards, writs, assessments, warrants of attachment, tax
        liens or executions or similar processes which, alone or in the
        aggregate, are reasonably likely to have a Material Adverse Effect are
        rendered, issued or levied; or

                (i)  CREDIT DOCUMENTS.  Any Credit Document or any material term
        thereof shall cease to be, or be asserted by Borrower or any of its
        Subsidiaries not to be, a legal, valid and binding obligation of
        Borrower or any of its Subsidiaries enforceable in accordance with its
        terms; or

                (j)  ERISA.  Any Reportable Event which constitutes grounds for
        the termination of any Employee Benefit Plan by the PBGC or for the
        appointment of a trustee by the PBGC to administer any Employee Benefit

        within the meaning of Title IV of ERISA or a trustee shall be appointed
        by the PBGC to administer any Employee Benefit Plan; or

                (k)  CHANGE OF CONTROL.  Any Change of Control shall occur; or

                (l)  MATERIAL ADVERSE EFFECT.  Any event(s) or condition(s)
        which is(are) reasonably likely to have a Material Adverse Effect shall
        occur or exist.

     6.02.      REMEDIES.  At any time after the occurrence and during the
continuance of any event of default (other than an event of default referred to
in SUBPARAGRAPH 6.01(f) or 6.01(g)), Agent may, with the consent of the Required
Lenders, or shall, upon instructions from the Required Lenders, by written
notice to Borrower, (a) terminate the Commitments and the obligations of the
Lenders to make Loans and/or (b) declare all outstanding Obligations payable by
Borrower to be immediately due and payable without presentment, demand, protest
or any other notice of any kind, all of which are hereby expressly waived,
anything contained herein or in the Amended and Restated Notes to the contrary
notwithstanding.  Upon the occurrence or existence of any Event of Default
described in SUBPARAGRAPH 6.01(f) or 6.01(g), immediately and without notice,
(1) the Commitments and the obligations of the Lenders to make Loans shall
automatically terminate and (2) all outstanding Obligations payable by Borrower
hereunder shall automatically become immediately due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived, anything contained herein or in the Amended and
Restated Notes to the contrary notwithstanding.  In addition to the foregoing
remedies, upon the occurrence or existence of any Event of Default, Agent may
exercise any other right, power or remedy available to it under any of the
Credit Documents or otherwise by law, either by suit in equity or by action at
law, or both.

SECTION VII.    THE AGENT AND RELATIONS AMONG LENDERS.

        7.01.   APPOINTMENT, POWERS AND IMMUNITIES.  Each Lender hereby appoints
and authorizes Agent to act as its agent hereunder and under the other Credit
Documents with such powers as are expressly delegated to Agent by the terms of
this Agreement and the other Credit Documents, together with such other powers
as are reasonably incidental thereto.  Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in any
other Credit Document, be a trustee for any Lender or have any fiduciary duty to
any Lender.  Notwithstanding anything to the contrary contained herein Agent
shall not be required to take any action which is contrary to this Agreement or
any other Credit Document or any applicable Governmental Rule.  Neither Agent
nor any Lender shall be responsible to any other Lender for any recitals,
statements, representations or warranties made by Borrower or any of its
Subsidiaries contained in this Agreement or in any other Credit Document, for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Credit Document or for any failure by Borrower or
any of its Subsidiaries to perform their respective obligations hereunder or
thereunder.  Agent may employ agents and attorneys-in-fact and shall not be
responsible to any Lender for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care.  Neither Agent nor any of
its directors, officers, employees, agents or advisors shall be responsible to
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Credit Document or in connection herewith or therewith,
except for its or their own gross negligence or willful misconduct.  Except as
otherwise provided under this Agreement, Agent shall take such action with
respect to the Credit Documents as shall be directed by the Required Lenders.

     7.02.      RELIANCE BY AGENT.  Agent shall be entitled to rely upon any
certificate, notice or other document (including any cable, telegram, facsimile
or telex) believed by it in good faith to be genuine and correct and to have
been signed or sent by or on behalf of the proper Person or Persons, and upon
advice and statements of legal counsel, independent accountants and other
experts selected by Agent with reasonable care.  As to any other matters not
expressly provided for by this Agreement, Agent shall not be required to take
any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Lenders and shall in all
cases be fully protected by the Lenders in acting, or in refraining from acting,
hereunder or under any other Credit Document in accordance with the instructions
of the Required Lenders, and such instructions of the Required Lenders and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders.

     7.03.      DEFAULTS.  Agent shall not be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default unless Agent has received a
written notice from a Lender or Borrower, referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"Notice of Default".  If Agent receives such a notice of the occurrence of a
Default or Event of Default, Agent shall give prompt notice thereof to the
Lenders.  Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders; PROVIDED,
HOWEVER, that until Agent shall have received such directions, Agent may (but
shall not be obligated to) take such action, or refrain


                                       60

<PAGE>

from taking such action, with respect to such Default or Event of Default as
it shall deem advisable in the best interest of the Lenders.

     7.04.      INDEMNIFICATION.  Without limiting the Obligations of
Borrower hereunder, each Lender agrees to indemnify Agent, ratably in
accordance with their Proportionate Shares, for any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may at any
time be imposed on, incurred by or asserted against Agent in any way relating
to or arising out of this Agreement or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or
thereby or the enforcement of any of the terms hereof or thereof; PROVIDED,
HOWEVER, that no Lender shall be liable for any of the foregoing to the
extent they arise from Agent's gross negligence or willful misconduct.  Agent
shall be fully justified in refusing to take or in continuing to take any
action hereunder unless it shall first be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action. The
obligations of each Lender under this PARAGRAPH 7.04 shall survive the
payment and performance of the Obligations, the termination of this Agreement
and any Lender ceasing to be a party to this Agreement (with respect to
events which occurred prior to the time such Lender ceased to be a Lender
hereunder).
     7.05.      NON-RELIANCE.  Each Lender represents that it has, independently
and without reliance on Agent, or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own appraisal of the
business, prospects, management, financial condition and affairs of Borrower and
the Subsidiaries and its own decision to enter into this Agreement and agrees
that it will, independently and without reliance upon Agent or any other Lender,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own appraisals and decisions in taking or not taking
action under this Agreement.  Neither Agent nor any of its affiliates nor any of
their respective directors, officers, employees, agents or advisors shall (a) be
required to keep any Lender informed as to the performance or observance by
Borrower or any of its Subsidiaries of the obligations under this Agreement or
any other document referred to or provided for herein or to make inquiry of, or
to inspect the properties or books of Borrower or any of its Subsidiaries; (b)
have any duty or responsibility to provide any Lender with any credit or other
information concerning Borrower or any of its Subsidiaries which may come into
the possession of Agent, except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by Agent
hereunder; or (c) be responsible to any Lender for (i) any recital, statement,
representation or warranty made by Borrower or any officer, employee or agent of
Borrower in this Agreement or in any of the other Credit Documents, (ii) the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any Credit Document, (iii) the value or sufficiency of the
Collateral or the validity or perfection of any of the liens or security
interests intended to be created by the Credit Documents, or (iv) any failure by
Borrower to perform its obligations under this Agreement or any other Credit
Document.

        7.06.   RESIGNATION OR REMOVAL OF AGENT.  Agent may resign at any time
by giving thirty (30) days prior written notice thereof to Borrower and the
Lenders, and Agent may be removed at any time with or without cause by the
Required Lenders.  Upon any such resignation or removal,


                                       61

<PAGE>


the Required Lenders shall have the right to appoint a successor agent, which
agent, if not a lender, shall be reasonably acceptable to borrower; PROVIDED,
HOWEVER, that Borrower shall have no right to approve a successor Agent if a
Default or an Event of Default has occurred and is continuing.  Upon the
acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from the duties and obligations thereafter arising
hereunder.  After any retiring Agent's resignation or removal hereunder as
Agent, the provisions of this SECTION VII shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Agent.

     7.07.      AUTHORIZATION.  Agent is hereby authorized by the Lenders to
execute, deliver and perform, each of the Credit Documents to which Agent is or
is intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

     7.08.      AGENT IN ITS INDIVIDUAL CAPACITY.  Agent and its affiliates may
make loans to, accept deposits from and generally engage in any kind of banking
or other business with Borrower and its Subsidiaries and Affiliates as though
Agent were not Agent hereunder.  With respect to Loans, if any, made by Agent in
its capacity as a Lender, Agent in its capacity as a Lender shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" or "Lenders" shall include Agent in its capacity as a Lender.

SECTION VIII.   MISCELLANEOUS.

        8.01.   NOTICES.  Except as otherwise provided herein, all notices,
requests, demands, consents, instructions or other communications to or upon
Borrower, any Lender or Agent under this Agreement or the other Credit Documents
shall be in writing and faxed, mailed or delivered, if to Borrower or Agent, at
its respective facsimile number or address set forth below or, if to any Lender,
at the address or facsimile number specified beneath the heading "Address for
Notices" under the name of such Lender in SCHEDULE I (or to such other facsimile
number or address for any party as indicated in any notice given by that party
to the other parties).  All such notices and communications shall be effective
(a) when sent by Federal Express or other overnight service of recognized
standing, on the Business Day following the deposit with such service; (b) when
mailed, first class postage prepaid and addressed as aforesaid through the
United States Postal Service, upon receipt; (c) when delivered by hand, upon
delivery; and (d) when faxed, upon confirmation of receipt; PROVIDED, HOWEVER,
that any notice delivered to Agent under SECTION II shall not be effective until
received by Agent.

Each Notice of Borrowing, Notice of Conversion and Notice of Interest Period
Selection shall be given by Borrower to Agent's office located at the address
referred to above during Agent's normal business hours; PROVIDED, HOWEVER, that
any such notice received by Agent after 10:30 a.m. on any Business Day shall be
deemed received by Agent on the next Business Day.  In any case where this
Agreement authorizes notices, requests, demands or other communications by
Borrower to Agent or any Lender to be made by telephone or facsimile, Agent or
any Lender may conclusively presume that anyone purporting to be a person
designated in any incumbency certificate or other similar document received by
Agent or a Lender is such a person.

        8.02.   EXPENSES.  Borrower shall pay on demand, whether or not any Loan
is made hereunder, (a) all reasonable fees and expenses, including reasonable
attorneys' fees and expenses, incurred by Agent in connection with the
preparation, negotiation, execution and delivery of, and the exercise of its
duties under, this Agreement and the other Credit Documents, and the
preparation, negotiation, execution and delivery of amendments and waivers
hereunder and thereunder and (b) all reasonable fees and expenses, including
reasonable attorneys' fees and expenses, incurred by Agent and the Lenders in
the enforcement or attempted enforcement of any of the obligations or in
preserving any of Agent's or the Lenders' rights and remedies (including,
without limitation, all such fees and expenses incurred in connection with any
"workout" or restructuring affecting the Credit Documents or the Obligations or
any bankruptcy or similar proceeding involving Borrower or any of its
Subsidiaries).  As used herein, the term "reasonable


                                       63

<PAGE>

attorneys' fees and expenses" shall include, without limitation, allocable
costs and expenses of Agent's and Lenders' in-house legal counsel and staff.
The obligations of Borrower under this PARAGRAPH 8.02 shall survive the
payment and performance of the Obligations and the termination of this
Agreement.

        8.03.   INDEMNIFICATION.  To the fullest extent permitted by law,
Borrower agrees to protect, indemnify, defend and hold harmless Agent, the
Lenders and their Affiliates and their respective directors, officers,
employees, agents and advisors ("INDEMNITEES") from and against any and all
liabilities, losses, damages or expenses of any kind or nature and from any
suits, claims or demands (including in respect of or for reasonable attorney's
fees and other expenses) arising on account of or in connection with any matter
or thing or action or failure to act by Indemnitees, or any of them, arising out
of or relating to the Credit Documents or any transaction contemplated thereby,
including without limitation any use by Borrower of any proceeds of the Loans,
except to the extent such liability arises from the willful misconduct or gross
negligence of such Indemnitee.  Upon receiving knowledge of any suit, claim or
demand asserted by a third party that Agent or any Lender believes is covered by
this indemnity, Agent or such Lender shall give Borrower notice of the matter
and an opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel satisfactory to Agent or such Lender, as the case may be.  Agent or such
Lender may also require Borrower to defend the matter.  Any failure or delay of
Agent or any Lender to notify Borrower of any such suit, claim or demand shall
not relieve Borrower of its obligations under this PARAGRAPH 8.03 but shall
reduce such obligations to the extent of any increase in those obligations
caused solely by any such failure or delay which is unreasonable.  The
obligations of Borrower under this PARAGRAPH 8.03 shall survive the payment and
performance of the Obligations and the termination of this Agreement.

        8.04.   WAIVERS; AMENDMENTS.  Any term, covenant, agreement or condition
of this Agreement or any other Credit Document may be amended or waived, and any
consent under this Agreement or any other Credit Document may be given, if such
amendment, waiver or consent is in writing and is signed by Borrower and the
required Lenders (or Agent on behalf of the required Lenders with the written
approval of the Required Lenders); PROVIDED, HOWEVER that:

                (a)  Any amendment, waiver or consent which would (i) increase
        the Total Commitment, (ii) extend the Maturity Date, (iii) reduce the
        principal of or interest on any Loan or any fees or other amounts
        payable for the account of the Lenders hereunder, (iv) extend any
        scheduled principal, interest or fee payment date, (v) amend this
        PARAGRAPH 8.04, (vi)  releases the Amended and Restated Guaranty, (vii)
        amends the definition of Required Lenders, or (viii) release any
        substantial and material part of the Collateral (except for any release
        permitted by Subparagraph 2.12(e)), must be in writing and signed or
        approved in writing by all Lenders;

                (b)  Any amendment, waiver or consent which increases or
        decreases the Proportionate Share of any Lender must be in writing and
        signed by such Lender; and


                                       64

<PAGE>

                (c)  Any amendment, waiver or consent which affects the rights
        or obligations of Agent must be in writing and signed by Agent.

No failure or delay by Agent or any Lender in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or of
any other right hereunder or thereunder nor shall any single or partial exercise
of any such right preclude any other further exercise thereof or of any other
right hereunder or thereunder.  Unless otherwise specified in such waiver or
consent, a waiver or consent given hereunder shall be effective only in the
specific instance and for the specific purpose for which given.

     8.05.      SUCCESSORS AND ASSIGNS.

                (a)  BINDING EFFECT.  This Agreement and the other Credit
        Documents shall be binding upon and inure to the benefit of Borrower,
        the Lenders, Agent, all future holders of the Amended and Restated Notes
        and their respective successors and permitted assigns, except that
        Borrower may not assign or transfer any of its rights or obligations
        under any Credit Document without the prior written consent of Agent and
        each Lender.  All references in this Agreement to any Person shall be
        deemed to include all successors and assigns of such Person.

                (b)  PARTICIPATIONS.  Any Lender may at any time sell to one or
        more banks or other financial institutions ("PARTICIPANTS")
        participating interests in any Loan owing to such Lender, any Amended
        and Restated Note held by such Lender, any Commitment of such Lender or
        any other interest of such Lender under this Agreement and the other
        Credit Documents.  In the event of any such sale by a Lender of
        participating interests, such Lender's obligations under this Agreement
        shall remain unchanged, such Lender shall remain solely responsible for
        the performance thereof, such Lender shall remain the holder of its
        Amended and Restated Notes for all purposes under this Agreement and
        Borrower and Agent shall continue to deal solely and directly with such
        Lender in connection with such Lender's rights and obligations under
        this Agreement.  Any agreement pursuant to which any such sale is
        effected may require the selling Lender to obtain the consent of the
        Participant in order for such Lender to agree in writing to any
        amendment, waiver or consent of a type specified in CLAUSE (i), (ii),
        (iii) OR (iv) OF SUBPARAGRAPH 8.04(a) but may not otherwise require the
        selling Lender to obtain the consent of such Participant to any other
        amendment, waiver or consent hereunder.  Borrower also agrees that any
        Lender which has transferred any participating interest in its
        Commitment or Loans shall, notwithstanding any such transfer, be
        entitled to the full benefits accorded such Lender under PARAGRAPH 2.09,
        PARAGRAPH 2.10, and PARAGRAPH 2.11, as if such Lender had not made such
        transfer.

                (c)  ASSIGNMENTS.  Any Lender may, at any time, sell and assign
        to any Lender or any Eligible Assignee (individually, an "ASSIGNEE
        LENDER") all or a portion of its rights and obligations under this
        Agreement and the other Credit Documents (such a sale and assignment to
        be referred to herein as an "ASSIGNMENT") pursuant to an assignment
        agreement in the form of EXHIBIT G (an "ASSIGNMENT AGREEMENT"), executed
        by each


                                       65

<PAGE>


        Assignee Lender and such assignor Lender (an "ASSIGNOR LENDER")
        and delivered to Agent for its acceptance and recording in the Register;
        PROVIDED, HOWEVER, that:

                        (i)     Without the written consent of Agent and, if no
                Default or Event of Default has occurred and is continuing,
                Borrower (which consent of Agent and Borrower shall not be
                unreasonably withheld), no Lender may make any Assignment to any
                Assignee Lender which is not, immediately prior to such
                Assignment, a Lender hereunder or an Affiliate thereof; or

                        (ii)    Without the written consent of Agent and, if no
                Default or Event of Default has occurred and is continuing,
                Borrower (which consent of Agent and Borrower shall not be
                unreasonably withheld), no Lender may make any Assignment to any
                Assignee Lender if, after giving effect to such Assignment, the
                Commitment of such Lender or such Assignee Lender would be less
                than Five Million Dollars ($5,000,000) (except that a Lender may
                make an Assignment which reduces its Commitment to zero without
                the written consent of Borrower and Agent); or

                        (iii)   Without the written consent of Agent and, if no
                Default or Event of Default has occurred and is continuing,
                Borrower (which consent of Agent and Borrower shall not be
                unreasonably withheld), no Lender may make any Assignment which
                does not assign and delegate an equal pro rata interest in such
                Lender's Loans, Commitment and all other rights, duties and
                obligations of such Lender under this Agreement and the other
                Credit Documents.

        Upon such execution, delivery, acceptance and recording of each
        Assignment Agreement, from and after the Assignment Effective Date
        determined pursuant to such Assignment Agreement, (A) each  Assignee
        Lender thereunder shall be a Lender hereunder with a Proportionate Share
        as set forth on ATTACHMENT 1 TO SUCH ASSIGNMENT AGREEMENT (under the
        caption "Proportionate Share After Assignment") and shall have the
        rights, duties and obligations of such a Lender under this Agreement and
        the other Credit Documents, and (B) the Assignor Lender thereunder shall
        be a Lender with a Proportionate Share as set forth on ATTACHMENT 1 TO
        SUCH ASSIGNMENT AGREEMENT (under the caption "Proportionate Share After
        Assignment"), or, if the Proportionate Share of the Assignor Lender has
        been reduced to 0%, the Assignor Lender shall cease to be a Lender and
        to have any obligation to make any Loan; PROVIDED, HOWEVER, that any
        such Assignor Lender which ceases to be a Lender shall continue to be
        entitled to the benefits of any provision of this Agreement which by its
        terms survives the termination of this Agreement.  Each Assignment
        Agreement shall be deemed to amend SCHEDULE I to the extent, and only to
        the extent, necessary to reflect the addition of each Assignee Lender,
        the deletion of each Assignor Lender which reduces its Proportionate
        Share to 0% and the resulting adjustment of Proportionate Shares arising
        from the purchase by each Assignee Lender of all or a portion of the
        rights and obligations of an Assignor Lender under this Agreement and
        the other Credit Documents.  On or prior to the Assignment Effective
        Date determined pursuant to each Assignment Agreement, Borrower, at its
        own expense, shall execute and


                                       66

<PAGE>

        deliver to Agent, in exchange for the surrendered Amended and
        Restated Note of the Assignor Lender thereunder, a new Amended and
        Restated Note to the order of each Assignee Lender thereunder (with
        each new Amended and Restated Note to be in an amount equal to the
        Commitment assumed by such Assignee Lender) and, if the Assignor
        Lender is continuing as a Lender hereunder, a new Amended and
        Restated Note to the order of the Assignor Lender (with the new
        Amended and Restated Note to be in an amount equal to the Commitment
        retained by it).  Each such new Amended and Restated Note shall be
        dated the Closing Date and each shall otherwise be in the form of the
        Amended and Restated Note replaced thereby.  The Amended and Restated
        Notes surrendered by the Assignor Lender shall be returned by Agent
        to Borrower marked "replaced".  Each Assignee Lender which was not
        previously a Lender hereunder and which is not incorporated under the
        laws of the United States of America or a state thereof shall, within
        three (3) Business Days of becoming a Lender, deliver to Borrower and
        Agent two duly completed copies of United States Internal Revenue
        Service Form 1001 or 4224 (or successor applicable form), as the case
        may be, certifying in each case that such Lender is entitled to
        receive payments under this Agreement without deduction or
        withholding of any United States federal income taxes.

                (d)  REGISTER.  Agent shall maintain at its address referred to
        in PARAGRAPH 8.01 a copy of each Assignment Agreement delivered to it
        and a register (the "REGISTER") for the recordation of the names and
        addresses of the Lenders and the Proportionate Shares of each Lender
        from time to time.  The entries in the Register shall be conclusive in
        the absence of manifest error, and Borrower, Agent and the Lenders may
        treat each Person whose name is recorded in the Register as the owner of
        the Loans recorded therein for all purposes of this Agreement.  The
        Register shall be available for inspection by Borrower or any Lender at
        any reasonable time and from time to time upon reasonable prior notice.

                (e)  REGISTRATION.  Upon its receipt of an Assignment Agreement
        executed by an Assignor Lender and an Assignee Lender (and, to the
        extent required by SUBPARAGRAPH 8.05(c), by Borrower and Agent) together
        with payment to Agent by Assignor Lender of a registration and
        processing fee of $4000, Agent shall (i) promptly accept such Assignment
        Agreement and (ii) on the Effective Date determined pursuant thereto
        record the information contained therein in the Register and give notice
        of such acceptance and recordation to the Lenders and Borrower.  Agent
        may, from time to time at its election, prepare and deliver to the
        Lenders and Borrower a revised SCHEDULE I reflecting the names,
        addresses and respective Proportionate Shares of all Lenders then
        parties hereto.

                (f)  CONFIDENTIALITY.  Agent and the Lenders may disclose the
        Credit Documents and any financial or other information relating to
        Borrower or any Subsidiary to each other or, with the consent of
        Borrower, to any potential Participant or Assignee Lender.
        8.06.   SETOFF; SECURITY INTEREST.

                (a)  SETOFF.  In addition to any rights and remedies of the
        Lenders provided by law, each Lender shall have the right, with the
        prior consent of Agent but without prior notice
                                       67

<PAGE>

        to or consent of Borrower, any such notice and consent being
        expressly waived by Borrower to the extent permitted by applicable
        law, upon the occurrence and during the continuance of an Event of
        Default, to set-off and apply against the Obligations any amount
        owing from such Lender to Borrower. The aforesaid right of set-off
        may be exercised by such Lender against Borrower or against any
        trustee in bankruptcy, debtor in possession, assignee for the benefit
        of creditors, receiver or execution, judgment or attachment creditor
        of Borrower or against anyone else claiming through or against
        Borrower or such trustee in bankruptcy, debtor in possession,
        assignee for the benefit of creditors, receiver, or execution,
        judgment or attachment creditor, notwithstanding the fact that such
        right of set-off may not have been exercised by such Lender at any
        prior time.  Each Lender agrees promptly to notify Borrower after any
        such set-off and application made by such Lender, PROVIDED that the
        failure to give such notice shall not affect the validity of such
        set-off and application.

                (b)  SECURITY INTEREST.  As security for the Secured
        Obligations, Borrower hereby grants to Agent and each Lender, for the
        benefit of all Lenders, a continuing security interest in any and all
        deposit accounts or moneys of Borrower now or hereafter maintained with
        such Lender.  Each Lender shall have all of the rights of a secured
        party with respect to such security interest.

        8.07.   NO THIRD PARTY RIGHTS.  Nothing expressed in or to be implied
from this Agreement is intended to give, or shall be construed to give, any
Person, other than the parties hereto and their permitted successors and assigns
hereunder, any benefit or legal or equitable right, remedy or claim under or by
virtue of this Agreement or under or by virtue of any provision herein.

        8.08.   PARTIAL INVALIDITY.  If at any time any provision of this
Agreement is or becomes illegal, invalid or unenforceable in any respect under
the law or any jurisdiction, neither the legality, validity or enforceability of
the remaining provisions of this Agreement nor the legality, validity or
enforceability of such provision under the law of any other jurisdiction shall
in any way be affected or impaired thereby.

        8.09.   JURY TRIAL.  EACH OF BORROWER, THE LENDERS AND AGENT, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT
TO TRIAL BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT.

        8.10.   COUNTERPARTS.  This Agreement may be executed in any number of
identical counterparts, any set of which signed by all the parties hereto shall
be deemed to constitute a complete, executed original for all purposes.

        8.11.   CONFIDENTIALITY.  None of the Banks and Agent shall disclose to
any Person any information with respect to Borrower or any of its Subsidiaries
which is furnished pursuant to this Agreement or under the other Credit
Documents, except that any Bank or Agent may disclose any such information (a)
to its own directors, officers, employees, auditors, counsel and

                                       68

<PAGE>

other professional advisors and to its Affiliates if such Bank or Agent or
such Bank's or such Agent's holding or parent company in its sole discretion
determines that any such party should have access to such information; (b) to
another Bank or Agent; (c) if generally available to the public through no
fault of Agent or the Banks; (d) if required or appropriate in any report,
statement or testimony submitted to any Governmental Authority having or
claiming to have jurisdiction over such Bank or Agent; (e) if required or
appropriate in response to any summons or subpoena or in connection with any
litigation, to the extent permitted or deemed advisable by counsel; (f) to
comply with any Requirement of Law applicable to such Bank or Agent; (g) to
any Participant or Assignee Bank or any prospective Participant or Assignee
Bank, provided that such Participant or Assignee or prospective Participant
or assignee agrees in writing to be bound by this PARAGRAPH 8.11 prior to
disclosure; or (h) otherwise with the prior consent of Borrower; PROVIDED,
HOWEVER, that any disclosure made in violation of this agreement shall not
affect the obligations of Borrower and its Subsidiaries under this Agreement
and the other Credit Documents.

     8.12.      EFFECT; TERMINATION OF EXISTING CREDIT AGREEMENT.  Borrower,
Agent and the Lenders agree that, on and after the Closing Date, (a) this
Agreement, the Amended and Restated Notes and the Amended and Restated Guaranty
shall amend, restate in their entirety and replace, without novation, the
Existing Credit Agreement, the promissory notes issued by Borrower in connection
with the Existing Credit Agreement (the "Existing Notes") and the Guaranty dated
as of july 31, 1996 issued by the Domestic Subsidiaries in favor of Agent for
the benefit of the Lenders in connection with the Existing Credit Agreement (the
"Existing Guaranty"), respectively, (b) all obligations of the Lenders to make
loans or otherwise extend credit to Borrower under the Existing Credit Agreement
shall be terminated and (c) the Prior Security Documents and all of the Liens
granted to Agent and the Lenders thereunder shall terminate; PROVIDED, HOWEVER,
that such termination shall not (i) operate as a waiver of any right, power or
remedy of Agent or the Lender hereunder or under the Amended and Restated Notes,
the Amended and Restated Guaranty or any related document, instrument or
agreement or (ii) extinguish or impair any obligations of Borrower under the
Existing Credit Agreement, the Existing Notes, the Existing Guaranty or any
related document, instrument or agreement except to the extent any such
obligation is actually satisfied by Borrower or is covered in this Agreement or
the other Credit Documents; PROVIDED, FURTHER, that all of the Loans outstanding
under the Existing Credit Agreement shall remain outstanding and shall be deemed
to have been made under this Agreement on a pro rata basis by the Lenders
hereunder in accordance with their respective Proportionate Shares.
                        [the first signature page follows.]

                                     EXPLANATION

1.   The Applicable Margin for each Loan and the Commitment Fee Percentage will
     be set for each quarter and will vary depending upon whether such quarter
     is a Level 1 Quarter, a Level 2 Quarter, a Level 3 Quarter, a Level 4
     Quarter, OR a Level 5 Quarter.

2.   The Closing Date through the quarter ending on or about June 30, 1999 will
     be a Level 2 Quarter.

3.   Each quarter thereafter will be a Level 1 Quarter, a Level 2 Quarter, a
     Level 3 Quarter, a Level 4 Quarter, OR a Level 5  Quarter depending upon
     Borrower's Debt/EBITDA Ratio for the consecutive four-quarter period which
     ended with the second quarter prior to such quarter.

4.   Examples:

     (a)  For the consecutive four-quarter period ending on or about  September
          30, 1999, Borrower's Debt/EBITDA Ratio was 1.30.  The quarter ending
          on or about  March 31, 2000 will be a Level  3 Quarter.

                          AMENDED AND RESTATED GUARANTY

     THIS AMENDED AND RESTATED GUARANTY (this "Guaranty"), dated as of March 29,
1999 is executed by each of the undersigned (each such entity and each entity
which hereafter executes and delivers a Subsidiary Joinder in substantially the
form of Attachment 1 hereto to be referred to herein as a "Guarantor"), in favor
of ABN AMRO BANK N.V., a Netherlands public company acting through its San
Francisco Representative Office, acting as agent (in such capacity, "Agent") for
the financial institutions which are from time to time parties to the Credit
Agreement referred to in Recital A below (collectively, the "Lenders").

                                    RECITALS

     A. Pursuant to a Credit Agreement dated as of July 31, 1996 (as amended to
the date hereof, the "Existing Credit Agreement"), among ADAC Laboratories, a
California corporation ("Borrower"), the Lenders and Agent, the Lenders have
agreed to extend certain credit facilities to Borrower upon the terms and
subject to the conditions set forth therein. The availability of the credit
facilities under such Existing Credit Agreement was subject, among other
conditions, to the execution and delivery of each Guarantor of a Guaranty dated
as of July 31, 1996 (the "Existing Guaranty").

     B. Borrower has requested Agent and the Lenders to amend the Existing
Credit Agreement in certain respects. Pursuant to an Amended and Restated Credit
Agreement dated the date hereof (the "Credit Agreement"), among Borrower, Agent
and the Lenders, Agent and the Lenders have agreed to amend and restate the
Existing Credit Agreement upon the terms and subject to the conditions set forth
therein including, without limitation, (i) receipt by Agent of this Guaranty,
duly executed by each existing Domestic Subsidiary of Borrower, which amends,
and for convenience of reference, restates the Existing Guaranty as so amended
in its entirety and (ii) the receipt by Agent of Subsidiary Joinders, duly
executed by each future Domestic Subsidiary of Borrower. Each of the undersigned
Guarantors is a Domestic Subsidiary of Borrower and expects to continue to
derive substantial direct and indirect benefit from the transactions
contemplated by the Credit Agreement.

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, each Guarantor hereby agrees with Agent, for the ratable benefit
of the Lenders and Agent, that the Existing Guaranty shall be amended and
restated to read in its entirety as follows:

     2.   GUARANTY.

          (a)  PAYMENT GUARANTY.  Each Guarantor unconditionally guarantees and
     promises to pay and perform as and when due, whether at stated maturity,
     upon acceleration or otherwise, any and all of the Guaranteed Obligations.
     If any Insolvency Proceeding relating to Borrower is commenced, each
     Guarantor further unconditionally guarantees and promises to pay and
     perform, upon the demand of Agent, any and all of the Guaranteed
     Obligations (including any and all Disallowed Post-Commencement Interest
     and Expenses) in accordance with the terms of the Credit Documents, whether
     or not such obligations are then due and payable by Borrower and whether or
     not such obligations are modified, reduced or discharged in such Insolvency
     Proceeding.  This Guaranty is a guaranty of payment and not of collection.

          (b)  CONTINUING GUARANTY.  This Guaranty is an irrevocable continuing
     guaranty of the Guaranteed Obligations which shall continue in effect until
     all obligations of the Lenders to extend credit to Borrower have terminated
     and all of the Guaranteed Obligations have been fully, finally and
     indefeasibly paid.  If any payment on any Guaranteed Obligation is set
     aside, avoided or rescinded or otherwise recovered from Agent or any
     Lender, such recovered payment shall constitute a Guaranteed Obligation
     hereunder and, if this Guaranty was previously released or terminated, it
     automatically shall be fully reinstated, as if such payment was never made.

          (c)  INDEPENDENT OBLIGATION.  The liability of each Guarantor
     hereunder is independent of the Guaranteed Obligations and of the
     obligations of each other Guarantor hereunder, and a separate action or
     actions may be brought and prosecuted against each Guarantor irrespective
     of whether action is brought against Borrower, any other Guarantor or any
     other guarantor of the Guaranteed Obligations or whether Borrower, any
     other Guarantor or any other guarantor of the Guaranteed Obligations is
     joined in any such action or actions.

          (d)  FRAUDULENT TRANSFER LIMITATION.  If, in any action to enforce
     this Guaranty, any court of competent jurisdiction determines that
     enforcement against any Guarantor for the full amount of the Guaranteed
     Obligations is not lawful under or would be subject to avoidance under
     Section 548 of the United States Bankruptcy Code or any applicable
     provision of any comparable law of any state or other jurisdiction, the
     liability of such Guarantor under this Guaranty shall be limited to the
     maximum amount lawful and not subject to such avoidance.

          (e)  TERMINATION.  Notwithstanding any termination of this Guaranty in
     accordance with PARAGRAPH 6 hereof, this Guaranty shall continue to be in
     full force and effect and applicable to any Guaranteed Obligations arising
     thereafter which arise because prior payments of Guaranteed Obligations are
     rescinded or otherwise required to be surrendered by Agent or any Lender
     after receipt.


                                      F-4

     Material Adverse Effect.

     Guarantor of this Guaranty are within the power of such Guarantor and have

     generally.

          (d)  NON-CONTRAVENTION.  The execution, delivery and performance by
     such Guarantor of this Guaranty do not (i) violate any Requirement of Law

     imposed by any Governmental Authority due and payable by such Guarantor
     other than those which are being challenged in good faith by appropriate
     proceedings and for which adequate reserves have been established.

          redemption or similar law or similar rights for marshalling;

               (x)    Any right to be informed by Agent or any Lender of the
          financial condition of Borrower, any other Guarantor or any other
          guarantor of the Guaranteed Obligations or any change therein or any
          other circumstances bearing upon the risk of nonpayment or
          nonperformance of the Guaranteed Obligations;

               (xi)   Until all obligations of Agent or any Lender to extend
          credit to Borrower have terminated and all of the Guaranteed
          Obligations have been fully, finally and indefeasibly paid, any right
          to revoke this Guaranty;

               (xii)  Any defense arising from an election for the application
          of Section 1111(b)(2) of the United States Bankruptcy Code which
          applies to the Guaranteed Obligations;

          the size of a deficiency judgment following any foreclosure on any
          security for the Guaranteed Obligations;

               (xv)   All rights and defenses arising out of an election of
          remedies by Agent or any Lender, even though that election of
          remedies, such as a nonjudicial foreclosure with respect to security
          for a Guaranteed Obligation, has destroyed such Guarantor's rights of
          subrogation and reimbursement against Borrower by the operation of
          Section 580d of the Code of Civil Procedure or otherwise; and

               (xvi)  All other rights and defenses available to such Guarantor
          by reason of Sections 2787 to 2855, inclusive, Section 2899 or Section
          3433


                                      F-9
<PAGE>

          of the California Civil Code or Section 3605 of the California
          Commercial Code.

     Without limiting the scope of any of the foregoing provisions of this
     Paragraph 5, and pursuant to the provisions of California Civil Code
     Section 2856, each Guarantor hereby further waives all rights and defenses
     that such Guarantor may have because the Guaranteed Obligations are secured
     by real property.  This means, among other things:

               (A)    Agent or any Lender may collect from any Guarantor without
          first foreclosing on any real or personal property collateral pledged
          by Borrower.

               (B)    If Agent or any Lender forecloses on any real property
          collateral pledged by Borrower:

                      (1)     The amount of the Guaranteed Obligations may be
               reduced only by the price for which that collateral is sold at
               the foreclosure sale, even if the collateral is worth more than
               the sale price.

                      (2)     Agent or any Lender may collect from any Guarantor
               even if Agent or any Lender, by foreclosing on the real property
               collateral, has destroyed any right such Guarantor or any other
               Guarantor may have to collect from Borrower.

     This is an unconditional and irrevocable waiver of any rights and defenses
     each Guarantor may have because the Guaranteed Obligations are secured by
     real property.  These rights and defenses include, but are not limited to,
     any rights or defenses based upon Section 580a, 580b, 580d, or 726 of the
     California Code of Civil Procedure.

          (c)  FINANCIAL CONDITION OF BORROWER, ETC.  Each Guarantor is fully
     aware of the financial condition and affairs of Borrower.  Each Guarantor
     has executed this Guaranty without reliance upon any representation,
     warranty, statement or information concerning Borrower furnished to such
     Guarantor by Agent or any Lender and has, independently and without
     reliance on Agent or any Lender, and based on such documents and
     information as it has deemed appropriate, made its own appraisal of the
     financial condition and affairs of Borrower and of other circumstances
     affecting the risk of nonpayment or nonperformance of the Guaranteed
     Obligations.  Each Guarantor is in a position to obtain, and assumes full
     responsibility for obtaining, any additional information about the
     financial condition and affairs of Borrower and of other circumstances
     affecting the risk of nonpayment or nonperformance of the Guaranteed
     Obligations and will, independently and without reliance upon Agent or any
     Lender, and based on such documents and information as it shall deem


                                      F-10
<PAGE>

     appropriate at the time, continue to make its own appraisals and decisions
     in taking or not taking action in connection with this Guaranty.

     6.   SUBORDINATION.  Each Guarantor hereby subordinates any and all debts,
liabilities and obligations owed to such Guarantor by Borrower or any Subsidiary
of Borrower (the "SUBORDINATED OBLIGATIONS") to the Guaranteed Obligations as
provided in this PARAGRAPH 6.

          (a)  PROHIBITED PAYMENTS, ETC.  Until the occurrence of a Default or
     an Event of Default or any default by any Guarantor hereunder, each
     Guarantor and its Subsidiaries may receive regularly scheduled payments
     from Borrower on account of Subordinated Obligations.  After the occurrence
     and during the continuance of any Default or Event of Default or any
     default by any Guarantor hereunder (including the commencement and
     continuation of any Insolvency Proceeding relating to Borrower, however,
     unless Agent or Required Lenders otherwise requests, no Guarantor shall,
     nor shall it permit any of its Subsidiaries to, demand, accept or take any
     action to collect any payment on account of the Subordinated Obligations.

          (b)  PRIOR PAYMENT OF GUARANTEED OBLIGATIONS.  In any Insolvency
     Proceeding relating to Borrower, each Guarantor agrees that Agent and the
     Lenders shall be entitled to receive payment of all Guaranteed Obligations
     (including any and all Disallowed Post-Commencement Interest and Expenses)
     before such Guarantor or any of its Subsidiaries receives payment of any
     Subordinated Obligations.

          (c)  TURN-OVER.  After the occurrence and during the continuance of
     any Default or Event of Default (including the commencement and
     continuation of any Insolvency Proceeding relating to Borrower, each
     Guarantor and its Subsidiaries shall, if Agent or Required Lenders so
     requests, collect, enforce and receive payments on account of the
     Subordinated Obligations as trustee for Agent and the Lenders and deliver
     such payments to Agent on account of the Guaranteed Obligations (including
     any and all Disallowed Post-Commencement Interest and Expenses), together
     with any necessary endorsements or other instruments of transfer, but
     without reducing or affecting in any manner the liability of such Guarantor
     under the other provisions of this Guaranty.

          (d)  AGENT AUTHORIZATION.  After the occurrence and during the
     continuance of any Default or Event of Default or any default by a
     Guarantor hereunder (including the commencement and continuation of any
     Insolvency Proceeding relating to Borrower, Agent is authorized and
     empowered (but without any obligation to so do), in its discretion, (i) in
     the name of each Guarantor and its Subsidiaries, to collect and enforce,
     and to submit claims in respect of, Subordinated Obligations and to apply
     any amounts received thereon to the Guaranteed Obligations (including any
     and all Disallowed Post-Commencement


                                      F-11
<PAGE>

     Interest and Expenses), and (ii) to require each Guarantor (A) to collect
     and enforce, and to submit claims in respect of, Subordinated Obligations
     and (B) to pay any amounts received on such obligations to Agent for
     application to the Guaranteed Obligations (including any and all Disallowed
     Post-Commencement Interest and Expenses).

     7.   GENERAL PLEDGE; SETOFF.

          (a)  PLEDGE.  In addition to all liens upon and rights of setoff
     against the property of any Guarantor given to Agent or any Lender by law
     or separate agreement to secure the liabilities of any Guarantor hereunder,
     to the extent permitted by law, each Guarantor hereby grants to Agent (for
     the ratable benefit of Agent and the Lenders), as security for such
     Guarantor's obligations hereunder, a security interest in all monies,
     deposit accounts, securities and other property of such Guarantor now or
     hereafter in the possession of or on deposit with Agent or any Lender,
     whether held in a general or special account or deposit, or for safekeeping
     or otherwise; and Agent shall have all rights and remedies of a secured
     party with respect to such property.

          (b)  SETOFF.  In addition to any rights and remedies of Agent or any
     Lender provided by law, Agent and the Lenders (with the prior consent of
     Agent) shall have the right, without prior notice to any Guarantor, any
     such notice being expressly waived by each Guarantor to the extent
     permitted by applicable law, upon the occurrence and during the continuance
     of a Default or an Event of Default, to set-off and apply against the
     Guaranteed Obligations any amount owing from Agent or any Lender to such
     Guarantor, including all deposits, accounts and moneys of such Guarantor
     then or thereafter maintained with Agent or any Lender, at or at any time
     after, the happening of any of the above mentioned events.

          (c)  NONWAIVER.  No security interest or right of setoff shall be
     deemed to have been waived by any act or conduct on the part of Agent or
     any Lender or by any failure to exercise such right of setoff or to enforce
     such security interest, or by any delay in so doing; and every right of
     setoff and security interest shall continue in full force and effect until
     such right of setoff or security interest is specifically waived or
     released by an instrument in writing executed by Agent.

     8.   CONTRIBUTION AMONG GUARANTORS.  The Guarantors desire to allocate
among themselves, in a fair and equitable manner, their rights of contribution
from each other when any payment is made by any Guarantor under this Guaranty.
Accordingly, if any payment is made by any Guarantor under this Guaranty (a
"FUNDING GUARANTOR") that exceeds its Fair Share, the Funding Guarantor shall be
entitled to a contribution from each other Guarantor in the amount of such other
Guarantor's Fair Share Shortfall, so that all such contributions shall cause
each Guarantor's Aggregate Guaranty Payments to equal its Fair Share.  The
amounts payable as contributions hereunder shall be determined


                                      F-12
<PAGE>

by the Funding Guarantor as of the date on which the related payment or
distribution is made by the Funding Guarantor, and such determination shall be
binding on the other Guarantors absent manifest error. The allocation and right
of contribution among the Guarantors set forth in this Paragraph 8 shall not be
construed to limit in any way the liability of any Guarantor under this Guaranty
or the amount of the Guaranteed Obligations.

     9.   MISCELLANEOUS.

          (a)  NOTICES.  Except as otherwise provided herein, all notices,

          (b)  PAYMENTS.  Each Guarantor shall make all payments required
     hereunder to Agent, or its order, at Agent's office located at the address
     set forth in SUBPARAGRAPH 9(a) hereof, or at such other office as Agent may
     designate, on demand, in Dollars.  If any amounts required to be paid by a
     Guarantor under this Guaranty are not paid when due, such Guarantor shall
     pay interest on the aggregate, outstanding balance of such amounts from the
     date due until those amounts are paid in full at a per annum rate equal to
     the Base Rate plus two percent (2.00%), such rate to change from time to
     time as the Base Rate shall change.

          (c)  EXPENSES.  Each Guarantor shall pay on demand (i) all reasonable
     fees and expenses, including reasonable attorneys' fees and expenses,
     incurred by Agent in connection with the preparation, execution and
     delivery of, and the exercise of its duties under, this Guaranty and the
     preparation, execution and delivery of amendments and waivers hereunder and
     (ii) all reasonable fees and expenses, including reasonable attorneys' fees
     and expenses, incurred by Agent and the Lenders in connection with the
     enforcement or attempted enforcement of this Guaranty or any of the
     Guaranteed Obligations or in preserving any of Agent's or the Lenders'
     rights and remedies (including, without limitation, all such fees and
     expenses incurred in connection with any "workout" or restructuring
     affecting the Credit Documents or the Guaranteed Obligations or any
     bankruptcy or similar proceeding involving Guarantor, any other Guarantor,
     Borrower or any of their affiliates).

          (d)  WAIVERS; AMENDMENTS.  This Guaranty may not be amended or
     modified, nor may any of its terms be waived, except by written instruments
     signed by each Guarantor and Agent to the extent permitted pursuant to
     Section


                                      F-16
<PAGE>

     8.04 of the Credit Agreement. Each waiver or consent under any provision
     hereof shall be effective only in the specific instances for the purpose
     for which given. No failure or delay on Agent's or any Lender's part in
     exercising any right hereunder shall operate as a waiver thereof or of any
     other right nor shall any single or partial exercise of any such right
     preclude any other further exercise thereof or of any other right.

          (e)  ASSIGNMENTS.  This Guaranty shall be binding upon and inure to
     the benefit of Agent, the Lenders, the Guarantors and their respective
     successors and assigns; PROVIDED, HOWEVER, that no Guarantor may assign or
     transfer any of its rights and obligations under this Guaranty without the
     prior written consent of Agent and the Lenders, and, PROVIDED, FURTHER,
     that Agent and any Lender may sell, assign and delegate their respective
     rights and obligations hereunder only as permitted by the Credit Agreement.
     All references in this Guaranty to any Person shall be deemed to include
     all permitted successors and assigns of such Person.

          (f)  CUMULATIVE RIGHTS, ETC.  The rights, powers and remedies of Agent
     and the Lenders under this Guaranty shall be in addition to all rights,
     powers and remedies given to Agent and the Lenders by virtue of any
     applicable law, rule or regulation of any Governmental Authority, the
     Credit Agreement, any other Credit Document or any other agreement, all of
     which rights, powers, and remedies shall be cumulative and may be exercised
     successively or concurrently without impairing Agent's or any Lender's
     rights hereunder.  Each Guarantor waives any right to require Agent or any
     Lender to proceed against any Person or to exhaust any Collateral or to
     pursue any remedy in Agent's or such Lender's power.

          (g)  PAYMENTS FREE OF TAXES, ETC.  All payments made by each Guarantor
     under this Guaranty shall be made by each Guarantor free and clear of and
     without deduction for any and all present and future taxes, levies,
     charges, deductions and withholdings.  In addition, each Guarantor shall
     pay upon demand any stamp or other taxes, levies or charges of any
     jurisdiction with respect to the execution, delivery, registration,
     performance and enforcement of this Guaranty.  If any taxes, levies,
     charges or other amounts are required to be withheld from any amounts
     payable to Agent or any Lender hereunder, the amounts so payable to Agent
     or such Lender shall be increased to the extent necessary to yield to Agent
     or such Lender (after payment of all such amounts) any such amounts payable
     hereunder in the amounts specified in this Guaranty.  Upon request by Agent
     or any Lender, each Guarantor shall furnish evidence satisfactory to Agent
     or such Lender that all requisite authorizations and approvals by, and
     notices to and filings with, governmental authorities and regulatory bodies
     have been obtained and made and that all requisite taxes, levies and
     charges have been paid.

          (h)  PARTIAL INVALIDITY.  If at any time any provision of this
     Guaranty is or becomes illegal, invalid or unenforceable in any respect
     under the law or any


                                      F-17
<PAGE>

     jurisdiction, neither the legality, validity or enforceability of the

                                    RECITALS


     A.   Assignor Lender is one of the lenders which is a party to the Amended

<PAGE>

     3.   ASSIGNMENT EFFECTIVE NOTICE.  Upon (a) receipt by Agent of five (5)
counterparts of this Assignment Agreement (to each of which is attached a fully

each Assignee Lender (and, to the extent required by SUBPARAGRAPH 8.05(c) OF THE
CREDIT AGREEMENT, by Borrower and Agent) and (b) payment to Agent of the
registration and processing fee specified in SUBPARAGRAPH 8.05(e) OF THE CREDIT
AGREEMENT by Assignor Lender, Agent will transmit to Borrower, Assignor Lender
and each Assignee Lender an Assignment Effective Notice substantially in the

     4.   ASSIGNMENT EFFECTIVE DATE.  At or before 12:00 noon (local time of
Assignor Lender) on the Assignment Effective Date, each Assignee Lender shall
pay to Assignor Lender, in immediately available or same day funds, an amount
equal to the purchase price, as agreed between Assignor Lender and such Assignee
Lender (the "PURCHASE PRICE"), for the Proportionate Share purchased by such
Assignee Lender hereunder.  Effective upon receipt by Assignor Lender of the
Purchase Price payable by each Assignee Lender, the sale, assignment and
delegation to such Assignee Lender of such Proportionate Share as described in

     5.   PAYMENTS AFTER THE ASSIGNMENT EFFECTIVE DATE.  Assignor Lender and
each Assignee Lender hereby agree that Agent shall, and hereby authorize and
direct Agent to, allocate amounts payable under the Credit Agreement and the
other Credit Documents as follows:

          (a)  All principal payments made after the Assignment Effective Date
     with respect to each Proportionate Share assigned to an Assignee Lender
     pursuant to this Assignment Agreement shall be payable to such Assignee
     Lender.

          (b)  All interest, fees and other amounts accrued after the Assignment
     Effective Date with respect to each Proportionate Share assigned to an
     Assignee Lender pursuant to this Assignment Agreement shall be payable to
     such Assignee Lender.

Assignor Lender and each Assignee Lender shall make any separate arrangements
between themselves which they deem appropriate with respect to payments between
them of amounts paid under the Credit Documents on account of the Proportionate
Share assigned to such Assignee Lender, and neither Agent nor Borrower shall
have any responsibility to effect or carry out such separate arrangements.

     6.   DELIVERY OF NOTES.  On or prior to the Assignment Effective Date,
Assignor Lender will deliver to Agent the Notes payable to Assignor Lender.  On
or prior to the Assignment Effective Date, Borrower will deliver to Agent new
Notes for each Assignee Lender and Assignor Lender, in each case in principal
amounts reflecting, in accordance with the Credit Agreement, their respective
Commitments (as adjusted pursuant to this Assignment Agreement).  As provided in
SUBPARAGRAPH 8.05(c) OF THE CREDIT AGREEMENT, each such new Note shall be dated

                                      G-2
<PAGE>

the Assignment Effective Date, Agent will send to each of Assignor Lender and
the Assignee Lenders its new Notes and will send to Borrower the superseded Note
payable to Assignor Lender, marked "Replaced."

     7.   DELIVERY OF COPIES OF CREDIT DOCUMENTS.  Concurrently with the
execution and delivery hereof, Assignor Lender will provide to each Assignee

copies of all documents delivered to Assignor Lender on or prior to the Closing
Date in satisfaction of the conditions precedent set forth in the Credit
Agreement.

     8.   FURTHER ASSURANCES.  Each of the parties to this Assignment Agreement
agrees that at any time and from time to time upon the written request of any
other party, it will execute and deliver such further documents and do such
further acts and things as such other party may reasonably request in order to
effect the purposes of this Assignment Agreement.

     9.   FURTHER REPRESENTATIONS, WARRANTIES AND COVENANTS.  Assignor Lender
and each Assignee Lender further represent and warrant to and covenant with each
other, Agent and the Lenders as follows:

          (a)  Other than the representation and warranty that it is the legal
     and beneficial owner of the interest being assigned hereby free and clear
     of any adverse claim, Assignor Lender makes no representation or warranty
     and assumes no responsibility with respect to any statements, warranties or
     representations made in or in connection with the Credit Agreement or the
     other Credit Documents or the execution, legality, validity,
     enforceability, genuineness, sufficiency or value of the Credit Agreement
     or the other Credit Documents furnished.

          (b)  Assignor Lender makes no representation or warranty and assumes
     no responsibility with respect to the financial condition of Borrower or
     any of its obligations under the Credit Agreement or any other Credit
     Documents.

          (c)  Each Assignee Lender confirms that it has received a copy of the
     Credit Agreement and such other documents and information as it has deemed
     appropriate to make its own credit analysis and decision to enter into this
     Assignment Agreement.

          (d)  Each Assignee Lender will, independently and without reliance
     upon Agent, Assignor Lender or any other Lender and based upon such
     documents and information as it shall deem appropriate at the time,
     continue to make its own credit decisions in taking or not taking action
     under the Credit Agreement and the other Credit Documents.

          (e)  Each Assignee Lender appoints and authorizes Agent to take such
     action as Agent on its behalf and to exercise such powers under the Credit


                                      G-3

     Agreement and the other Credit Documents as Agent is authorized to exercise
     by the terms thereof, together with such powers as are reasonably
     incidental thereto, all in accordance with SECTION VII OF THE CREDIT
     AGREEMENT.

          (f)  Each Assignee Lender agrees that it will perform in accordance
     with their terms all of the obligations which by the terms of the Credit
     Agreement and the other Credit Documents are required to be performed by it
     as a Lender.

          (g)  ATTACHMENT I hereto sets forth administrative information with
     respect to each Assignee Lender.

     10.  EFFECT OF THIS ASSIGNMENT AGREEMENT.  On and after the Assignment
Effective Date, (a) each Assignee Lender shall be a Lender with a Proportionate
Share equal to the Proportionate Share set forth under the caption
"Proportionate Share After Assignment" opposite such Assignee Lender's name on

Lender under the Credit Agreement and the other Credit Documents and (b)

Proportionate Share set forth under the caption "Proportionate Share After
Assignment" opposite Assignor Lender's name on ATTACHMENT I hereto and shall
have the rights, duties and obligations of such a Lender under the Credit
Agreement and the other Credit Documents, or, if the Proportionate Share of
Assignor Lender has been reduced to 0%, Assignor Lender shall cease to be a
Lender and shall have no further obligation to make any Loans.

     11.  MISCELLANEOUS.  This Assignment Agreement shall be governed by, and
construed in accordance with, the laws of the State of California.  Paragraph

                                    AGREEMENT

     NOW, THEREFORE, in consideration of the above recitals and for other good

Security Agreement and are hereby incorporated by reference.

     2. Grant of Security Interest. As security for the Secured Obligations,
Borrower hereby pledges and assigns to Agent (for the ratable benefit of the
Lenders and Agent) and grants to Agent (for the ratable benefit of the Lenders
and Agent) a security interest in all right, title and interest of Borrower in
and to the property described in Attachment 1 hereto, whether now owned or
hereafter


                                     H-1-2
<PAGE>
acquired (collectively and severally, the "Collateral"), which Attachment 1 is
incorporated herein by this reference.

     3. Representations and Warranties. Borrower represents and warrants to the
Lenders and Agent as follows:

          (a) Borrower is the legal and beneficial owner of the Collateral (or,
     in the case of after-acquired Collateral, at the time Borrower acquires
     rights in the Collateral, will be the legal and beneficial owner thereof).
     No other Person has (or, in the case of after-acquired Collateral, at the
     time Borrower acquires rights therein, will have) any right, title, claim
     or interest (by way of Lien, purchase option or otherwise) in, against or
     to the Collateral, other than Permitted Liens.

          (b) Agent has (or in the case of after-acquired Collateral, at the
     time Borrower acquires rights therein, will have) a first priority
     perfected security interest in the Collateral to the extent that a security
     interest in such Collateral can be perfected by the filing of a financing
     statement, and a security interest in all other Collateral, subject to no
     other Liens except for Permitted Liens.

          (c) All Equipment and Inventory are (i) located at the locations
     indicated in item 8 of the Collateral Certificate, (ii) in transit to such
     locations or (iii) in transit to a third party purchaser which will become
     obligated on a Receivable to Borrower upon receipt. Except for Equipment
     and Inventory referred to in clauses (ii) and (iii) of the preceding
     sentence, Borrower has exclusive possession and control of the Inventory
     and Equipment.

          (d) All Inventory has been (or, in the case of hereafter produced
     Inventory, will be) produced in compliance with all applicable Governmental
     Rules, including the Fair Labor Standards Act (if applicable).

          (e) Borrower keeps all records concerning the Receivables and the
     originals of all Related Contracts at its chief executive office located at
     the address set forth in item 2 of the Collateral Certificate.

          (f) Each Receivable is genuine and enforceable against the party
     obligated to pay the same (an "Account Debtor") free from any right of
     rescission, defense, setoff or discount.

          (g) Each insurance policy maintained by Borrower is validly existing
     and is in full force and effect. Borrower is not in default in any material
     respect under the provisions of any insurance policy, and there are no
     facts which, with the giving of notice or passage of time (or both), would
     result in such a default under any provision of any such insurance policy.


                                     H-1-3
<PAGE>
          (h) The information set forth in the Collateral Certificate is true,
     correct and accurate.

     4. Covenants. Borrower hereby agrees as follows:

          (a) Borrower, at Borrower's expense, shall promptly procure, execute
     and deliver to Agent all documents, instruments and agreements and perform
     all acts which are necessary, or which Agent may reasonably request, to
     establish, maintain, preserve, protect and perfect the Collateral, the Lien
     granted to Agent therein and the first priority of such Lien (subject to
     Permitted Liens) or to enable Agent to exercise and enforce its rights and
     remedies hereunder with respect to any Collateral. Without limiting the
     generality of the preceding sentence, Borrower shall (i) procure, execute
     and deliver to Agent all stock powers, endorsements, assignments, financing
     statements and other instruments of transfer requested by Agent, (ii)
     deliver to Agent promptly upon receipt all originals of Collateral
     consisting of instruments, documents and chattel paper in amounts exceeding
     $1,000,000 (provided, however that upon the occurrence of a Default, if
     requested by Agent, Borrower shall deliver to Agent promptly upon receipt
     all originals of Collateral consisting of instruments, documents and
     chattel paper in amounts of less than $1,000,000 but exceeding $100,000)
     and (iii) take such actions as may be necessary or reasonably requested by
     Agent to perfect the Lien of Agent in any Collateral consisting of
     investment property (including taking the actions required by Subparagraph
     4(f) hereof and, in those jurisdictions where appropriate, causing such
     Liens to be recorded or registered in the books of any financial
     intermediary or clearing corporation requested by Agent).

          (b) Borrower shall not use or permit any Collateral to be used in
     violation of (i) any provision of the Credit Agreement, this Security
     Agreement or any other Security Document, (ii) any applicable Governmental
     Rule where such use might have a Material Adverse Effect, or (iii) any
     policy of insurance covering the Collateral.

          (c) Borrower shall pay promptly when due all taxes and other
     governmental charges, all Liens and all other charges now or hereafter
     imposed upon, relating to or affecting any Collateral.

          (d) Without thirty (30) days prior written notice to Agent, Borrower
     shall not (i) change Borrower's name or place of business (or, if Borrower
     has more than one place of business, its chief executive office), or the
     office in which Borrower's records relating to Receivables or the originals
     of Related Contracts are kept, (ii) keep Collateral consisting of chattel
     paper and documents at any location other than its chief executive office
     set forth in item 2 of the Collateral Certificate, or (iii) keep Collateral


                                     H-1-4
<PAGE>
     consisting of Equipment, Inventory or other goods at any location other
     than the locations set forth in item 8 of the Collateral Certificate.

          (e) For each deposit account maintained by Borrower, Borrower shall
     (i) execute and deliver to the bank or other depository institution at
     which such deposit account is maintained (the "Depositary Bank") a Notice
     of Security Interest in the form of Attachment 2 hereto and (ii) use its
     best efforts to cause the Depositary Bank to execute and deliver to Agent
     an Acknowledgment and Agreement in the form set forth in such Notice of
     Security Interest (or in any other form acceptable to Agent in its sole
     discretion). Without ten (10) days prior written notice to Agent, Borrower
     shall not establish any deposit account not set forth in item 15 of the
     Collateral Certificate.

          (f) For each securities account and commodity account maintained by
     Borrower, Borrower shall (i) complete, execute and deliver to the bank,
     broker or other Person at which such account is maintained (the
     "Intermediary") a Notice of Security Interest in the form of Attachment 3
     hereto and (ii) cause the Intermediary to execute and deliver to Agent an
     Acknowledgment and Agreement in the form set forth in such Notice of
     Security Interest (or in any other form acceptable to Agent in its sole
     discretion). Without thirty (30) days prior written notice to Agent,
     Borrower shall not establish any securities account or commodity account
     not set forth in item 16 of the Collateral Certificate.

          (g) If requested by Agent, Borrower shall deposit, or cause to be
     deposited, all remittances, checks and other funds (in whatever form)
     received with respect to Receivables to a deposit account for which
     Borrower has complied with subparagraph 4(e) above and in which Agent has a
     first priority perfected security interest.

          (h) Borrower shall appear in and defend any action or proceeding which
     may affect its title to or Agent's interest in the Collateral if an adverse
     decision is reasonably likely to have a Material Adverse Effect.

          (i) If Agent gives value to enable Borrower to acquire rights in or
     the use of any Collateral, Borrower shall use such value for such purpose.

          (j) Borrower shall keep separate, accurate and complete records of the
     Collateral and shall provide Agent with such records and such other reports
     and information relating to the Collateral as Agent may reasonably request
     from time to time.

          (k) Borrower shall not surrender or lose possession of (other than to
     Agent), sell, encumber, lease, rent, option, or otherwise dispose of or
     transfer any Collateral or right or interest therein except as permitted in
     the


                                     H-1-5
<PAGE>
     Credit Agreement, and Borrower shall keep the Collateral free of all Liens
     except Permitted Liens.

          (l) Borrower shall, if requested by Agent, type, print or stamp
     conspicuously on the face of all original copies of all Collateral
     consisting of chattel paper and documents in excess of $100,000 not in the
     possession of Agent a legend satisfactory to Agent indicating that such
     chattel paper and documents are subject to the security interest granted
     hereby.

          (m) Borrower shall collect, enforce and receive delivery of the
     Receivables in accordance with past practice until otherwise notified by
     Agent.

          (n) Borrower shall comply with all material Requirements of Law
     applicable to Borrower which relate to the production, possession,
     operation, maintenance and control of the Collateral (including, without
     limitation, the Fair Labor Standards Act).

          (o) Borrower shall (i) carry and maintain insurance on the Collateral
     as required pursuant to Subparagraph 5.01(c) of the Credit Agreement, (ii)
     deliver to Agent from time to time, as Agent may request, schedules setting
     forth all insurance then in effect, and (iii) deliver to Agent copies of
     each policy of insurance which replaces, or evidences the renewal of, each
     existing policy of insurance at least fifteen (15) days prior to the
     expiration of such policy. Agent shall be named as additional insured or
     additional loss payee, as appropriate, on all liability and property
     insurance of Borrower and such policies shall contain such additional
     endorsements as shall be required by Agent. Prior to the occurrence and the
     continuance of an Event of Default, all proceeds of any property insurance
     paid as a result of any event or occurrence shall be paid to Borrower. All
     proceeds of any property insurance paid after the occurrence and during the
     continuance of an Event of Default shall be paid to Agent to be held as
     Collateral and applied as provided in the Credit Agreement or, at the
     election of the Required Lenders, returned to Borrower.

     5. Authorized Action by Agent. Borrower hereby irrevocably appoints Agent
as its attorney-in-fact and agrees that Agent may perform (but Agent shall not
be obligated to and shall incur no liability to Borrower or any third party for
failure so to do) any act which Borrower is obligated by this Security Agreement
to perform, and to exercise such rights and powers as Borrower might exercise
with respect to the Collateral, including, without limitation, the right to (a)
collect by legal proceedings or otherwise and endorse, receive and receipt for
all dividends, interest, payments, proceeds and other sums and property now or
hereafter payable on or on account of the Collateral; (b) enter into any
extension, reorganization, deposit, merger, consolidation or other agreement
pertaining to, or deposit,


                                     H-1-6
<PAGE>
surrender, accept, hold or apply other property in exchange for the Collateral;
(c) insure, process, preserve and enforce the Collateral; (d) make any
compromise or settlement, and take any action it deems advisable, with respect
to the Collateral; (e) pay any Indebtedness of Borrower relating to the
Collateral; and (f) execute UCC financing statements and other documents,
instruments and agreements required hereunder; provided, however, that Agent
shall not act pursuant to this appointment or otherwise hereunder unless an
Event of Default has occurred and is continuing. Borrower agrees to reimburse
Agent upon demand for all reasonable costs and expenses, including attorneys'
fees, Agent may incur while acting as Borrower's attorney-in-fact hereunder, all
of which costs and expenses are included in the Secured Obligations. Borrower
agrees that such care as Agent gives to the safekeeping of its own property of
like kind shall constitute reasonable care of the Collateral when in Agent's
possession; provided, however, that Agent shall not be required to make any
presentment, demand or protest, or give any notice and need not take any action
to preserve any rights against any prior party or any other Person in connection
with the Secured Obligations or with respect to the Collateral.

     6. Default and Remedies. Borrower shall be deemed in default under this
Security Agreement upon the occurrence and during the continuance of an Event of
Default, as that term is defined in the Credit Agreement. In addition to all
other rights and remedies granted to Agent by this Security Agreement, the
Credit Agreement, the other Credit Documents, the UCC and other applicable
Governmental Rules, Agent may, upon the occurrence and during the continuance of
any Event of Default, exercise any one or more of the following rights and
remedies: (a) collect, receive, appropriate or realize upon the Collateral or
otherwise foreclose or enforce Agent's security interests in any or all
Collateral in any manner permitted by applicable Governmental Rules or in this
Security Agreement; (b) notify any or all Account Debtors to make payments on
Receivables directly to Agent; (c) direct any Depositary Bank or Intermediary to
liquidate the account(s) maintained by it, pay all amounts payable in connection
therewith to Agent and/or deliver any proceeds thereof to Agent; (d) sell or
otherwise dispose of any or all Collateral at one or more public or private
sales, whether or not such Collateral is present at the place of sale, for cash
or credit or future delivery, on such terms and in such manner as Agent may
determine; (e) require Borrower to assemble the Collateral and make it available
to Agent at a place to be designated by Agent; (f) enter onto any property where
any Collateral is located and take possession thereof with or without judicial
process; and (g) prior to the disposition of the Collateral, store, process,
repair or recondition any Collateral consisting of goods, perform any
obligations and enforce any rights of Borrower under any Related Contracts or
otherwise prepare and preserve Collateral for disposition in any manner and to
the extent Agent deems appropriate. In furtherance of Agent's rights hereunder,
Borrower hereby grants to Agent an irrevocable, non-exclusive license
(exercisable without royalty or other payment by Agent) to use, license or
sublicense any patent, trademark, tradename, copyright or other intellectual
property in which Borrower now or hereafter has any right, title or interest,
together with the right of access to


                                     H-1-7
<PAGE>
all media in which any of the foregoing may be recorded or stored. In any case
where notice of any sale or disposition of any Collateral is required, Borrower
hereby agrees that seven (7) days notice of such sale or disposition is
reasonable.

     7. MISCELLANEOUS.

          (a) Notices. Except as otherwise specified herein, all notices,
     requests, demands, consents, instructions or other communications to or
     upon Borrower or Agent under this Security Agreement shall be given as
     provided in Paragraph 8.01 of the Credit Agreement.

          (b) Waivers; Amendments. Any term, covenant, agreement or condition of
     this Security Agreement may be amended or waived only as provided in the
     Credit Agreement. No failure or delay by Agent or any Lender in exercising
     any right hereunder shall operate as a waiver thereof or of any other right
     nor shall any single or partial exercise of any such right preclude any
     other further exercise thereof or of any other right. Unless otherwise
     specified in any such waiver or consent, a waiver or consent given
     hereunder shall be effective only in the specific instance and for the
     specific purpose for which given.

          (c) Successors and Assigns. This Security Agreement shall be binding
     upon and inure to the benefit of Agent, the Lenders and Borrower and their
     respective successors and assigns; provided, however, that Agent, the
     Lenders and Borrower may sell, assign and delegate their respective rights
     and obligations hereunder only as permitted by the Credit Agreement. Agent
     and the Lenders may disclose this Security Agreement as provided in the
     Credit Agreement.

          (d) Partial Invalidity. If at any time any provision of this Security
     Agreement is or becomes illegal, invalid or unenforceable in any respect
     under the law or any jurisdiction, neither the legality, validity or
     enforceability of the remaining provisions of this Security Agreement nor
     the legality, validity or enforceability of such provision under the law of
     any other jurisdiction shall in any way be affected or impaired thereby.

          (e) Cumulative Rights, etc. The rights, powers and remedies of Agent
     and the Lenders under this Security Agreement shall be in addition to all
     rights, powers and remedies given to Agent and the Lenders by virtue of any
     applicable Governmental Rule, the Credit Agreement, any other Credit
     Document or any other agreement, all of which rights, powers, and remedies
     shall be cumulative and may be exercised successively or concurrently
     without impairing Agent's rights hereunder. Borrower waives any right to
     require Agent or any Lender to proceed against any Person or to exhaust any
     Collateral or to pursue any remedy in Agent's or such Lender's power.


                                     H-1-8
<PAGE>
          (f) Payments Free of Taxes, Etc. All payments made by Borrower under
     this Security Agreement shall be made by Borrower free and clear of and
     without deduction for any and all present and future taxes, levies,
     charges, deductions and withholdings. In addition, Borrower shall pay upon
     demand any stamp or other taxes, levies or charges of any jurisdiction with
     respect to the execution, delivery, registration, performance and
     enforcement of this Security Agreement. Upon request by Agent, Borrower
     shall furnish evidence satisfactory to Agent that all requisite
     authorizations and approvals by, and notices to and filings with,
     governmental authorities and regulatory bodies have been obtained and made
     and that all requisite taxes, levies and charges have been paid.

          (g) Borrower's Continuing Liability. Notwithstanding any provision of
     this Security Agreement or any other Credit Document or any exercise by
     Agent of any of its rights hereunder or thereunder (including, without
     limitation, any right to collect or enforce any Collateral), (i) Borrower
     shall remain liable to perform its obligations and duties in connection
     with the Collateral (including, without limitation, the Related Contracts
     and all other agreements relating to the Collateral) and (ii) neither Agent
     nor any Lender shall assume any liability to perform such obligations and
     duties or to enforce any of Borrower's rights in connection with the
     Collateral (including, without limitation, the Related Contracts and all
     other agreements relating to the Collateral).

          (h) Governing Law. This Security Agreement shall be governed by and
     construed in accordance with the laws of the State of California without
     reference to conflicts of law rules (except to the extent otherwise
     provided in the UCC).

     2. GRANT OF SECURITY INTEREST. As security for the Secured Obligations,
Grantor hereby pledges and assigns to Agent (for the ratable benefit of the
Lenders and Agent) and grants to Agent (for the ratable benefit of the Lenders
and Agent) a security interest in all right, title and interest of Grantor in
and to the property described in Attachment 1 hereto, whether now owned or
hereafter acquired (collectively and severally, the "Collateral"), which
Attachment 1 is incorporated herein by this reference.

     3. REPRESENTATIONS AND WARRANTIES. Grantor represents and warrants to the
Lenders and Agent as follows:

          (a) Grantor is the legal and beneficial owner of the Collateral (or,
     in the case of after-acquired Collateral, at the time Grantor acquires
     rights in the Collateral, will be the legal and beneficial owner thereof).
     No other Person has (or, in the case of after-acquired Collateral, at the
     time Grantor acquires rights therein, will have) any right, title, claim or
     interest (by way of Lien, purchase option or otherwise) in, against or to
     the Collateral, other than Permitted Liens.

          (b) Agent has (or in the case of after-acquired Collateral, at the
     time Grantor acquires rights therein, will have) a first priority perfected
     security interest in the Collateral to the extent that a security interest
     in such Collateral can be perfected by the filing of a financing statement,
     and a security interest in all other Collateral, subject to no other Liens
     except for Permitted Liens.

          (c) All Equipment and Inventory are (i) located at the locations
     indicated in item 8 of the Collateral Certificate, (ii) in transit to such
     locations or (iii) in transit to a third party purchaser which will become
     obligated on a Receivable to Grantor upon receipt. Except for Equipment and
     Inventory referred to in clauses (ii) and (iii) of the preceding sentence,
     Grantor has exclusive possession and control of the Inventory and
     Equipment.

          (d) All Inventory has been (or, in the case of hereafter produced
     Inventory, will be) produced in compliance with all applicable Governmental
     Rules, including the Fair Labor Standards Act (if applicable).

          (e) Grantor keeps all records concerning the Receivables and the
     originals of all Related Contracts at its chief executive office located at
     the address set forth in item 2 of the Collateral Certificate.

          (f) Each Receivable is genuine and enforceable against the party
     obligated to pay the same (an "Account Debtor") free from any right of
     rescission, defense, setoff or discount.


                                     H-2-3
<PAGE>
          (g) Each insurance policy maintained by Grantor is validly existing
     and is in full force and effect. Grantor is not in default in any material
     respect under the provisions of any insurance policy, and there are no
     facts which, with the giving of notice or passage of time (or both), would
     result in such a default under any provision of any such insurance policy.

          (h) The information set forth in the Collateral Certificate is true,
     correct and accurate.

     4. COVENANTS. Grantor hereby agrees as follows:

          (a) Grantor, at Grantor's expense, shall promptly procure, execute and
     deliver to Agent all documents, instruments and agreements and perform all
     acts which are necessary, or which Agent may reasonably request, to
     establish, maintain, preserve, protect and perfect the Collateral, the Lien
     granted to Agent therein and the first priority of such Lien (subject to
     Permitted Liens) or to enable Agent to exercise and enforce its rights and
     remedies hereunder with respect to any Collateral. Without limiting the
     generality of the preceding sentence, Grantor shall (i) procure, execute
     and deliver to Agent all stock powers, endorsements, assignments, financing
     statements and other instruments of transfer requested by Agent, (ii)
     [deliver to Agent promptly upon receipt all originals of Collateral
     consisting of instruments, documents and chattel paper in amounts exceeding
     $1,000,000 (provided, however, that upon the occurrence of a Default, if
     requested by Agent, Grantor shall deliver to Agent promptly upon receipt
     all originals of Collateral consisting of instruments, documents and
     chattel paper in amounts of less than $1,000,000 but exceeding $100,000)]
     {for use in all Domestic Subsidiary Security Agreements other than ADAC
     Capital, LLC}[upon the occurrence of a Default, if requested by Agent,
     deliver to Agent promptly upon receipt all originals of Collateral
     consisting of instruments, documents and chattel paper in amounts exceeding
     $1,000,000] {for use in ADAC Capital, LLC Domestic Subsidiary Security
     Agreement}and (iii) take such actions as may be necessary or reasonably
     requested by Agent to perfect the Lien of Agent in any Collateral
     consisting of investment property (including taking the actions required by
     Subparagraph 4(f) hereof and, in those jurisdictions where appropriate,
     causing such Liens to be recorded or registered in the books of any
     financial intermediary or clearing corporation requested by Agent).

          (b) Grantor shall not use or permit any Collateral to be used in
     violation of (i) any provision of the Credit Agreement, this Security
     Agreement or any other Security Document, (ii) any applicable Governmental
     Rule where such use might have a Material Adverse Effect, or (iii) any
     policy of insurance covering the Collateral.

     governmental charges, all Liens and all other charges now or hereafter

          (d) Without thirty (30) days prior written notice to Agent, Grantor
     shall not (i) change Grantor's name or place of business (or, if Grantor

     of Related Contracts are kept, (ii) keep Collateral consisting of chattel
     paper and documents at any location other than its chief executive office

     consisting of Equipment, Inventory or other goods at any location other
     than the locations set forth in item 8 of the Collateral Certificate.

          (e) For each deposit account maintained by Grantor, Grantor shall (i)
     execute and deliver to the bank or other depository institution at which
     such deposit account is maintained (the "Depositary Bank") a Notice of
     Security Interest in the form of Attachment 2 hereto and (ii) use its best
     efforts to cause the Depositary Bank to execute and deliver to Agent an
     Acknowledgment and Agreement in the form set forth in such Notice of
     Security Interest (or in any other form acceptable to Agent in its sole
     discretion). Without ten (10) days prior written notice to Agent, Grantor
     shall not establish any deposit account not set forth in item 15 of the
     Collateral Certificate.

          (f) For each securities account and commodity account maintained by
     Grantor, Grantor shall (i) complete, execute and deliver to the bank,
     broker or other Person at which such account is maintained (the
     "Intermediary") a Notice of Security Interest in the form of Attachment 3
     hereto and (ii) cause the Intermediary to execute and deliver to Agent an
     Acknowledgment and Agreement in the form set forth in such Notice of
     Security Interest (or in any other form acceptable to Agent in its sole
     discretion). Without thirty (30) days prior written notice to Agent,
     Grantor shall not establish any securities account or commodity account not
     set forth in item 16 of the Collateral Certificate.

          (g) If requested by Agent, Grantor shall deposit, or cause to be
     deposited, all remittances, checks and other funds (in whatever form)
     received with respect to Receivables to a deposit account for which Grantor
     has complied with subparagraph 4(e) above and in which Agent has a first
     priority perfected security interest.

          (h) Grantor shall appear in and defend any action or proceeding which
     may affect its title to or Agent's interest in the Collateral if an adverse
     decision is reasonably likely to have a Material Adverse Effect.

     transfer any Collateral or right or interest therein except as permitted in
     the Credit Agreement, and, notwithstanding any provision of the Credit
     Agreement, Grantor shall keep the Collateral free of all Liens except
     Permitted Liens.

          (l) Grantor shall, if requested by Agent, type, print or stamp
     conspicuously on the face of all original copies of all Collateral
     consisting of chattel paper and documents in excess of $100,000 not in the
     possession of Agent a legend satisfactory to Agent indicating that such
     chattel paper and documents are subject to the security interest granted

     5. AUTHORIZED ACTION BY AGENT. Grantor hereby irrevocably appoints Agent as
its attorney-in-fact and agrees that Agent may perform (but Agent shall not be
obligated to and shall incur no liability to Grantor or any third party for
failure so to do) any act which Grantor is obligated by this Security Agreement
to perform, and to exercise such rights and powers as Grantor might exercise
with respect to the Collateral, including, without limitation, the right to (a)
collect by legal proceedings or otherwise and endorse, receive and receipt for
all dividends, interest, payments, proceeds and other sums and property now or
hereafter payable on or on account of the Collateral; (b) enter into any
extension, reorganization, deposit, merger, consolidation or other agreement
pertaining to, or deposit, surrender, accept, hold or apply other property in
exchange for the Collateral; (c) insure, process, preserve and enforce the
Collateral; (d) make any compromise or settlement, and take any action it deems
advisable, with respect to the Collateral; (e) pay any Indebtedness of Grantor
relating to the Collateral; and (f) execute UCC financing statements and other
documents, instruments and agreements required hereunder; provided, however,
that Agent shall not act pursuant to this appointment or otherwise hereunder
unless an Event of Default has occurred and is continuing. Grantor agrees to
reimburse Agent upon demand for all reasonable costs and expenses, including
attorneys' fees, Agent may incur while acting as Grantor's attorney-in-fact
hereunder, all of which costs and expenses are included in the Secured
Obligations. Grantor agrees that such care as Agent gives to the safekeeping of
its own property of like kind shall constitute reasonable care of the Collateral
when in Agent's possession; provided, however, that Agent shall not be required
to make any presentment, demand or protest, or give any notice and need not take
any action to preserve any rights against any prior party or any other Person in
connection with the Secured Obligations or with respect to the Collateral.

     6. DEFAULT AND REMEDIES. Grantor shall be deemed in default under this
Security Agreement upon the occurrence and during the continuance of an Event of
Default, as that term is defined in the Credit Agreement. In addition to all
other rights and remedies granted to Agent by this Security Agreement, the
Credit Agreement, the other Credit Documents, the UCC and other applicable
Governmental Rules, Agent may, upon the occurrence and during the continuance of
any Event of Default, exercise any one or more of the following rights and
remedies: (a) collect, receive, appropriate or realize upon the Collateral or
otherwise foreclose or enforce Agent's security interests in any or all
Collateral in any manner permitted by applicable Governmental Rules or in this
Security Agreement; (b) notify any or all Account Debtors to make payments on
Receivables directly to Agent; (c) direct any Depositary Bank or Intermediary to
liquidate the account(s) maintained by it, pay all amounts payable in connection
therewith to Agent and/or deliver any proceeds thereof to Agent; (d) sell or
otherwise dispose of any or all Collateral at one or more public or private
sales, whether or not such Collateral is present at the place of sale, for cash
or credit or future delivery, on such terms and in such manner as Agent may
determine; (e) require Grantor to assemble the Collateral and make it available
to Agent at a place to be designated by Agent; (f)


                                     H-2-7
<PAGE>
enter onto any property where any Collateral is located and take possession
thereof with or without judicial process; and (g) prior to the disposition of
the Collateral, store, process, repair or recondition any Collateral consisting
of goods, perform any obligations and enforce any rights of Grantor under any
Related Contracts or otherwise prepare and preserve Collateral for disposition
in any manner and to the extent Agent deems appropriate. In furtherance of
Agent's rights hereunder, Grantor hereby grants to Agent an irrevocable,
non-exclusive license (exercisable without royalty or other payment by Agent) to
use, license or sublicense any patent, trademark, tradename, copyright or other
intellectual property in which Grantor now or hereafter has any right, title or
interest, together with the right of access to all media in which any of the
foregoing may be recorded or stored. In any case where notice of any sale or
disposition of any Collateral is required, Grantor hereby agrees that seven (7)
days notice of such sale or disposition is reasonable.

     7. AUTHORIZATIONS, WAIVERS, ETC.

          (a) Authorizations. Grantor authorizes Agent and the Lenders, in their
     discretion, without notice to Grantor, irrespective of any change in the
     financial condition of Borrower, Grantor or any other guarantor of the

          accelerate or otherwise change the time for payment or performance of,

          against Borrower, Grantor, any other guarantor of the Secured

          credit to Borrower have terminated and all of the Secured Obligations
          have been fully, finally and indefeasibly paid, any right of

          to the Secured Obligations;

               (xiii) Any defense based upon any borrowing or grant of a

               (xiv) Any right it may have to a fair value hearing to determine

          security for the Secured Obligations;

               (xv) All rights and defenses arising out of an election of
          remedies by Agent or any Lender, even though that election of
          remedies, such as a nonjudicial foreclosure with respect to security
          for a Secured Obligation, has destroyed Grantor's rights of
          subrogation and reimbursement against Borrower by the operation of
          Section 580d of the Code of Civil Procedure or otherwise; and

               (xvi) All other rights and defenses available to Grantor by
          reason of Sections 2787 to 2855, inclusive, Section 2899 or Section

          Commercial Code.

          Without limiting the scope of any of the foregoing provisions of this
          Paragraph 5, and pursuant to the provisions of California Civil Code
          Section 2856, Grantor hereby further waives all rights and defenses
          that Grantor may have because the Secured Obligations are secured by
          real property.  This means, among other things:

                    (A) Agent or any Lender may collect from Grantor without
               first foreclosing on any real or personal property collateral
               pledged by Borrower.

                    (B) If Agent or any Lender forecloses on any real property
               collateral pledged by Borrower:

                         (1) The amount of the Secured Obligations may be
                    reduced only by the price for which that collateral is sold
                    at the foreclosure sale, even if the collateral is worth
                    more than the sale price.

                         (2) Agent or any Lender may collect from Grantor even
                    if Agent or any Lender, by foreclosing on the real property
                    collateral, has destroyed any right Grantor may have to
                    collect from Borrower.

          This is an unconditional and irrevocable waiver of any rights and
          defenses Grantor may have because the Secured Obligations are secured
          by real property. These rights and defenses include, but are not
          limited to, any rights or defenses based upon Section 580a, 580b,
          580d, or 726 of the California Code of Civil Procedure.

<PAGE>
          (c) Financial Condition of Borrower, Etc. Grantor is fully aware of
     the financial condition and affairs of Borrower. Grantor has executed this
     Security Agreement without reliance upon any representation, warranty,
     statement or information concerning Borrower furnished to Grantor by Agent
     or any Lender and has, independently and without reliance on Agent or any
     Lender, and based on such documents and information as it has deemed
     appropriate, made its own appraisal of the financial condition and affairs
     of Borrower and of other circumstances affecting the risk of nonpayment or
     nonperformance of the Secured Obligations. Grantor is in a position to
     obtain, and assumes full responsibility for obtaining, any additional
     information about the financial condition and affairs of Borrower and of
     other circumstances affecting the risk of nonpayment or nonperformance of
     the Secured Obligations and will, independently and without reliance upon
     Agent or any Lender, and based on such documents and information as it
     shall deem appropriate at the time, continue to make its own appraisals and
     decisions in taking or not taking action in connection with this Security
     Agreement.

     8. Miscellaneous.

               (b) Waivers; Amendments. Any term, covenant, agreement or
          condition of this Security Agreement may be amended or waived only as
          provided in the Credit Agreement. No failure or delay by Agent or any
          Lender in exercising any right hereunder shall operate as a waiver
          thereof or of any other right nor shall any single or partial exercise
          of any such right preclude any other further exercise thereof or of
          any other right. Unless otherwise specified in any such waiver or
          consent, a waiver or consent given hereunder shall be effective only
          in the specific instance and for the specific purpose for which given.

               (c) Successors and Assigns. This Security Agreement shall be
          binding upon and inure to the benefit of Agent, the Lenders and
          Grantor and their respective successors and assigns; provided,
          however, that Agent, the Lenders and Grantor may sell, assign and
          delegate their respective rights and obligations hereunder only as
          permitted by the Credit Agreement. Agent and the Lenders may disclose
          this Security Agreement as provided in the Credit Agreement.

               (d) Partial Invalidity. If at any time any provision of this
          Security Agreement is or becomes illegal, invalid or unenforceable in
          any respect under the law or any jurisdiction, neither the legality,
          validity or enforceability of the remaining provisions of this
          Security Agreement nor the legality, validity or enforceability of
          such provision under the law of any other jurisdiction shall in any
          way be affected or impaired thereby.

               (e) Cumulative Rights, etc. The rights, powers and remedies of
          Agent and the Lenders under this Security Agreement shall be in
          addition to all rights, powers and remedies given to Agent and the
          Lenders by virtue of any applicable Governmental Rule, the Credit
          Agreement, any other Credit Document or any other agreement, all of
          which rights, powers, and remedies shall be cumulative and may be
          exercised successively or concurrently without impairing Agent's
          rights hereunder. Grantor waives any right to


                                     H-2-13
<PAGE>
          require Agent or any Lender to proceed against any Person or to
          exhaust any Collateral or to pursue any remedy in Agent's or such
          Lender's power.

               (f) Payments Free of Taxes, Etc. All payments made by Grantor
          under this Security Agreement shall be made by Grantor free and clear
          of and without deduction for any and all present and future taxes,
          levies, charges, deductions and withholdings. In addition, Grantor
          shall pay upon demand any stamp or other taxes, levies or charges of
          any jurisdiction with respect to the execution, delivery,
          registration, performance and enforcement of this Security Agreement.
          Upon request by Agent, Grantor shall furnish evidence satisfactory to
          Agent that all requisite authorizations and approvals by, and notices
          to and filings with, governmental authorities and regulatory bodies
          have been obtained and made and that all requisite taxes, levies and
          charges have been paid.

               (g) Grantor's Continuing Liability. Notwithstanding any provision
          of this Security Agreement or any other Credit Document or any
          exercise by Agent of any of its rights hereunder or thereunder
          (including, without limitation, any right to collect or enforce any
          Collateral), (i) Grantor shall remain liable to perform its
          obligations and duties in connection with the Collateral (including,
          without limitation, the Related Contracts and all other agreements
          relating to the Collateral) and (ii) neither Agent nor any Lender
          shall assume any liability to perform such obligations and duties or
          to enforce any of Grantor's rights in connection with the Collateral
          (including, without limitation, the Related Contracts and all other
          agreements relating to the Collateral).

               (h) Governing Law. This Security Agreement shall be governed by
          and construed in accordance with the laws of the State of California
          without reference to conflicts of law rules (except to the extent
          otherwise provided in the UCC).

         3. REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants
to the Lenders and Agent as follows:

              (a) Borrower is the legal and beneficial owner of the Collateral
         (or, in the case of after-acquired Collateral, at the time Borrower
         acquires rights in the Collateral, will be the beneficial owner
         thereof). No other Person has (or, in the case of after-acquired
         Collateral, at the time Borrower acquires rights therein, will have)
         any right, title, claim or interest (by way of Lien, purchase option
         or otherwise) in, against or to the Collateral, other than Permitted
         Liens.

              (b) Agent has (or in the case of after-acquired Collateral, at
         the time Borrower acquires rights therein, will have) a first
         priority perfected security interest in the Collateral, subject to
         no other Liens other than Permitted Liens; provided, however, that
         (i) the security interest of Agent may be subject to Permitted Liens
         and (ii) Agent must make the filings with the Patent and Trademark
         Office contemplated by this Security Agreement to perfect its
         security interest in Borrower's Patents and Trademarks registered
         with that office.

              (c) Borrower has the sole, full and unencumbered right, title
         and interest in and to (i) each of the Trademarks described in
         Schedule A to Attachment 1 hereto for the goods and services covered
         by the registrations thereof, (ii) each of the Patents described in
         Schedule B to Attachment 1 hereto, (iii) each of the Copyrights
         described in Schedule C to Attachment 1 hereto and (iv) each of the
         Mask Works described in Schedule D to Attachment 1 hereto. Any
         registrations for such Trademarks and Patents are valid and
         enforceable and in full force and effect and none of the Patents has
         been abandoned or dedicated. According to the records of the
         Copyright Office, all registered Copyrights and Mask Works are valid
         and enforceable and in full force and effect.

              (d) Borrower does not own any Patents, Trademarks, Copyrights
         or Mask Works registered in, or the subject of pending applications
         in, the

                                     I-1-3

<PAGE>

         Patent and Trademark Office or the Copyright Office, other than those
         described in Schedules A, B, C and D to Attachment 1 hereto.

              (e) To the best of Borrower's knowledge, no claim has been made
         by any third party and remains unresolved that any of the Patents,
         Trademarks, Copyrights or Mask Works is invalid and unenforceable or
         violates or may violate the rights of any Person.

              (f) Set forth in Schedule E to Attachment 1 hereto is a
         complete list of all material licenses of Patents, Trademarks,
         Copyrights, Mask Works and Trade Secrets which Borrower has granted
         to any Person.

              (g) Set forth in Schedule F to Attachment 1 hereto is a
         complete list of all licenses of Patents, Trademarks, Copyrights,
         Mask Works and Trade Secrets which any Person has granted to
         Borrower.

              (h) Borrower has obtained from each employee who may be
         considered the inventor of patentable inventions (invented within
         the scope of such employee's employment with Borrower) an agreement
         to assign to Borrower all rights to such inventions, including
         Patents.

              (i) Borrower has taken all commercially reasonable steps to
         protect the secrecy and the validity under applicable law of all
         material Trade Secrets.

         4. COVENANTS OF BORROWER. Borrower hereby agrees as follows:

              (a) Borrower, at Borrower's expense, shall promptly procure,
         execute and deliver to Agent all documents, instruments and
         agreements and perform all acts which are necessary, or which Agent
         may reasonably request, to establish, maintain, preserve, protect
         and perfect the Collateral, the Lien granted to Agent therein and
         the first priority of such Lien or to enable Agent to exercise and
         enforce its rights and remedies hereunder with respect to any
         Collateral. Without limiting the generality of the preceding
         sentence, Borrower shall (i) execute all notices of security
         interest for each relevant type of intellectual property in forms
         suitable for filing with the Patent and Trademark Office or the
         Copyright Office, as applicable, substantially in the forms of
         Attachments 2 and 3 hereto or other forms reasonably acceptable to
         Agent and (ii) take all commercially reasonable steps in any
         proceeding before the Patent and Trademark Office, the Copyright
         Office or any similar office or agency in any other country or any
         political subdivision thereof, to diligently prosecute or maintain,
         as applicable, each application and registration of material
         Patents, Trademarks, Copyrights and Mask Works, including filing of
         renewals, affidavits of use, affidavits of incontestability and
         opposition, interference and cancellation proceedings (except to the
         extent that dedication,
                                     I-1-4


<PAGE>
         abandonment or invalidation is permitted hereunder or would not be
         reasonably likely to have a Material Adverse Effect).

              (b) Borrower shall not use any Collateral or permit any
         Collateral to be used in violation of (i) any provision of the
         Credit Agreement, this Security Agreement or any other Credit
         Document, (ii) any applicable Governmental Rule or Contractual
         Obligation where such use could reasonably be expected to have a
         Material Adverse Effect, or (iii) any policy of insurance covering
         the Collateral where such use is reasonably likely to have a
         Material Adverse Effect.

              (c) Borrower shall pay promptly when due all taxes and other
         governmental charges, all Liens and all other charges now or
         hereafter imposed upon, relating to or affecting any Collateral.

              (d) Borrower shall appear in and defend any action or
         proceeding which may affect its title to or Agent's security
         interest in the Collateral if an adverse decision is reasonably
         likely to have a Material Adverse Effect.

              (e) Borrower shall keep separate, accurate and complete records
         of the Collateral and shall permit Agent to examine and make copies
         of such records and provide such reports and information relating to
         the Collateral as Agent may reasonably request from time to time.

              (f) Borrower shall not surrender or lose possession of (other
         than to Agent), sell, encumber, lease, rent, option, license or
         otherwise dispose of or transfer any Collateral or right or interest
         therein except as permitted in the Credit Agreement, and Borrower
         shall keep the Collateral free of all Liens except Permitted Liens.

              (g) Borrower (either directly or through licensees) will make
         commercially reasonable efforts to continue to use the Trademarks
         which are material to Borrower's business or operations in
         connection with each and every trademark class of goods or services
         applicable to its current line of products or services as reflected
         in its current catalogs, brochures, price lists or similar materials
         in order to maintain such Trademarks in full force and effect free
         from any claim of abandonment for nonuse, and Borrower will not (and
         will not permit any licensee thereof to) do any act or knowingly
         omit to do any act whereby Borrower's rights in any such material
         Trademark is reasonably likely to become invalidated. Borrower will
         not do any act, or omit to do any act, whereby the Patents or Patent
         Registrations which are material to Borrower's business or
         operations may become abandoned or dedicated or the remedies
         available against potential infringers weakened if such action or
         omission would be reasonably likely to have a Material Adverse
         Effect and shall notify Agent immediately if it knows of any reason
         or has reason to know that any such Patent Registration may become

                                     I-1-5



<PAGE>

         abandoned or dedicated. Borrower will not do any act or omit to do
         any act, whereby the Copyrights or Mask Works which are material to
         Borrower's business or operations may become abandoned or dedicated
         or the remedies available against potential infringers weakened if
         such action or omission would be reasonably likely to have a
         Material Adverse Effect, and shall notify Agent immediately if it
         knows of any reason or has reason to know that any such Copyright or
         Mask Work may become abandoned or dedicated.

              (h) Borrower will promptly notify Agent upon the filing, either
         by Borrower or through any agent, employee, licensee or designee, of
         (i) an application for the registration of any Patent, Trademark,
         Copyright or Mask Work with the Patent and Trademark Office or the
         Copyright Office or any similar office or agency in any other
         country or any political subdivision thereof, (ii) any assignment of
         any Patent or Trademark, which Borrower may acquire from a third
         party, with the Patent and Trademark Office or any similar office or
         agency in any other country or any political subdivision thereof, or
         (iii) any assignment of any Copyright or Mask Work, which Borrower
         may acquire from a third party, with the Copyright Office or any
         similar office or agency in any other country or any political
         subdivision thereof.

              (i) Borrower shall (i) make application to the Patent and
         Trademark Office to register any material unpatented but patentable
         inventions developed by Borrower or its employees (within the scope
         of their employment), unless Borrower, in the exercise of its
         prudent business judgment, deems any such Patent not to have any
         significant commercial value or determines that its rights
         thereunder are better preserved as a Trade Secret, (ii) make
         application to the Patent and Trademark Office to register any
         registerable but unregistered material Trademarks used by Borrower
         in connection with its products or services unless Borrower in the
         exercise of its prudent business judgment, deems any such Trademark
         not to have any significant commercial value, and (iii) make
         application to the Copyright Office to register any material
         unregistered Copyright or Mask Work to which Borrower has rights
         unless Borrower in the exercise of its prudent business judgment,
         deems any such Copyright or Mask Work not to have any significant
         commercial value or determines that its rights thereunder are better
         protectable as a Trade Secret.

              (j) Borrower shall (i) use proper statutory notice in connection
         with its use of the Trademarks, Copyrights and Mask Works,
         (ii) maintain consistent standards of quality in its manufacture of
         products sold under the Trademarks or provision of services in
         connection with the Trademarks, and (iii) take all commercially
         reasonable steps to protect the secrecy and the validity under
         applicable law of all material Trade Secrets.

                                     I-1-6

<PAGE>
              (k) If any Executive Officer of Borrower learns of any use by
         any Person of any term or design likely to cause confusion with any
         Trademark, Borrower shall promptly notify Agent of such use and of
         all steps taken and to be taken to remedy any infringement of such
         Trademark.

              (l) Borrower shall maintain with each employee who may have
         access to any material Trade Secrets of Borrower an agreement by
         which such employee agrees not to disclose such Trade Secrets and
         with each employee who may be the inventor of patentable inventions
         (invented within the scope of such employee's employment) an
         invention assignment agreement requiring such employee to assign all
         rights to such inventions, including, patents and patent
         applications, to Borrower and further requiring such employee to
         cooperate fully with Borrower, its successors in interest, including
         Agent, and their counsel, in the prosecution of any patent
         application or in any litigation involving the invention, whether
         such cooperation is required during such employee's employment with
         Borrower or after the termination of such employment.

         5. AUTHORIZED ACTION BY AGENT. Borrower hereby irrevocably appoints
Agent as its attorney-in-fact and agrees that Agent may perform (but Agent
shall not be obligated to and shall incur no liability to Borrower or any
third party for failure so to do) any act which Borrower is obligated by this
Security Agreement to perform, and to exercise such rights and powers as
Borrower might exercise with respect to the Collateral, including, without
limitation, the right to (a) collect by legal proceedings or otherwise and
endorse, receive and receipt for all royalties, payments, proceeds and other
sums and property now or hereafter payable on or on account of the Collateral;
(b) enter into any extension, reorganization, deposit, merger, consolidation or
other agreement pertaining to, or deposit, surrender, accept, hold or apply
other property in exchange for the Collateral; (c) insure, process, preserve and
enforce the Collateral; (d) make any compromise or settlement, and take any
action it deems advisable, with respect to the Collateral; (e) pay any
indebtedness of Borrower relating to the Collateral; and (f) execute UCC
financing statements and other documents, instruments and agreements required
hereunder; provided, however, that Agent shall exercise such powers only after
the occurrence and during the continuance of an Event of Default. In furtherance
of the powers granted in this paragraph 5, Borrower shall execute and deliver to
Agent a Special Power of Attorney in the form of Attachment 4 hereto. Borrower
agrees to reimburse Agent upon demand for all reasonable costs and expenses,
including reasonable attorneys' fees, Agent may incur while acting as Borrower's
attorney-in-fact hereunder, all of which costs and expenses are included in the
Secured Obligations. Borrower agrees that such care as Agent gives to the
safekeeping of its own property of like kind shall constitute reasonable care of
the Collateral when in Agent's possession; provided, however, that Agent shall
not be required to make any presentment, demand or protest, or give any notice
and need not take any

                                     I-1-7

<PAGE>

action to preserve any rights against any prior party or any other Person
in connection with the Secured Obligations or with respect to the Collateral.

         6. DEFAULT AND REMEDIES. Borrower shall be deemed in default under
this Security Agreement upon the occurrence and during the continuance of an
Event of Default, as that term is defined in the Credit Agreement. In
addition to all other rights and remedies granted to Agent by this Security
Agreement, the Credit Agreement, the other Credit Documents, the UCC and
other applicable Governmental Rules, Agent may, upon the occurrence and
during the continuance of any Event of Default, exercise any one or more of
the following rights and remedies: (a) collect, receive, appropriate or
realize upon the Collateral or otherwise foreclose or enforce Agent's
security interests in any or all Collateral in any manner permitted by
applicable Governmental Rules or in this Security Agreement; (b) notify any
or all licensees to make payments on Receivables directly to Agent; (c) sell
or otherwise dispose of any or all Collateral at one or more public or
private sales, whether or not such Collateral is present at the place of
sale, for cash or credit or future delivery, on such commercially reasonable
terms and in such commercially reasonable manner as Agent may determine; (d)
upon ten (10) Business Days' prior notice to Borrower, direct Borrower not to
make any further use of the Patents, the Trademarks (or any mark similar
thereto), the Copyrights (or any work deriving therefrom), or the Mask Works
for any purpose; (e) upon ten (10) Business Days' prior notice to Borrower,
license, whether general, special or otherwise, and whether on an exclusive
or nonexclusive basis, any of the Patents, Trademarks, Copyrights or Mask
Works, throughout the world for such term or terms, on such conditions, and
in such manner, as Agent shall in its sole discretion determine; (f) enforce
(and upon notice to Borrower have the exclusive right to enforce) against any
licensee or sublicensee all rights and remedies of Borrower in, to and under
any one or more license agreements with respect to the Collateral (without
assuming any obligations or liability thereunder), and take or refrain from
taking any action under any thereof; and (g) in addition to the foregoing, in
order to implement the assignment, sale or other disposal of any of the
Collateral, pursuant to the authority granted in paragraph 5 hereof, execute

         7.       INDEMNIFICATION AND RELEASE.

               (a) Borrower assumes all responsibility and liability arising
         from the use of the Patents, Trademarks, Copyrights and Mask Works,
         and Borrower hereby indemnifies and holds Agent, each other Agent
         and each Lender and their respective directors, officers, employees,
         agents and any of their respective Affiliates ("Indemnitees")
         harmless from and against any claim, suit, loss, damage or expense
         (including reasonable attorneys' fees and

                                     I-1-8

<PAGE>

         expenses) arising out of or in connection with any alleged
         infringement of any patent, trademark, service mark, trade name,
         trade secret, copyright or mask work of a third party or alleged
         defect in any product manufactured, promoted or sold by Borrower (or
         any Affiliate of Borrower) in connection with any Patent, Trademark,
         Copyright or Mask Work or out of the manufacture, promotion, labeling,
         sale or advertisement of any product or service by Borrower (or any
         Affiliate of Borrower); provided, however, that the foregoing indemnity
         shall not extend to any use by Agent or any Lender (or any of their
         respective Affiliates) of any Patent, Trademark, Copyright or Mask Work
         which constitutes gross negligence or willful misconduct. Borrower
         agrees that Agent, the Agent and the Lenders do not assume, and shall
         have no responsibility for, the payment of any sums due or to become
         due under any agreement or contract included in the Collateral or the
         performance of any obligations to be performed under or with respect to
         any such agreement or contract by Borrower, and Borrower hereby agrees
         to indemnify and hold each Indemnitee harmless with respect to any and
         all claims by any Person relating thereto.

              (b) Borrower agrees to indemnify and hold the Indemnitees
         harmless and against any claim, suit, loss, damage or expense
         (including reasonable attorneys' fees and expenses) arising out of
         or in connection with any action taken or omitted to be taken by
         Agent hereunder with respect to any license agreement of Borrower,
         other than actions taken or omitted to be taken through the gross
         negligence or willful misconduct of such Indemnities or any breach
         of this Agreement or the other Credit Documents.

              (c) Borrower agrees to indemnify and hold the Indemnitees
         harmless and against any claim, suit, loss, damage or expense
         (including reasonable attorneys' fees and expenses) arising out of
         or in connection with any claim, suit or proceeding instituted by
         Borrower or in which Borrower participates.

              (d) Borrower hereby releases the Indemnitees from any claims,
         causes of action and demands at any time arising out of or with
         respect to any actions taken or omitted to be taken by Agent under
         the powers of attorney granted in paragraph 5 hereof, other than
         actions taken or omitted to be taken through the gross negligence or
         willful misconduct of such Indemnitees or any breach of this
         Agreement or the other Credit Documents.

              (e) Borrower agrees to cause Agent to be named as an additional
         insured with respect to any policy of insurance held by Borrower
         from time to time covering product liability or intellectual
         property infringement risk.

              (f) Nothing contained in this Paragraph 7 shall, however, be
         deemed to require Borrower to indemnify or hold harmless any
         Indemnitee

                                     I-1-9

<PAGE>

         from any losses, costs, claims or damages arising from or relating
         to such Indemnitee's gross negligence or willful misconduct.

     (b) WAIVERS; AMENDMENTS. Any term, covenant, agreement or
condition of this Security Agreement may be amended or waived only
as provided in the Credit Agreement. No failure or delay by Agent in

such right preclude any other further exercise thereof or of any
other right. Unless otherwise specified in any such waiver or
consent, a waiver or consent given hereunder shall be effective only
in the specific instance and for the specific purpose for which

     (c) SUCCESSORS AND ASSIGNS. This Security Agreement shall be

in any respect under the law of any jurisdiction, neither the

of such provision under the law of any other jurisdiction shall in
any way be affected or impaired thereby.

     (e) CUMULATIVE RIGHTS, ETC. The rights, powers and remedies of

rights, powers and remedies given to Agent and the Lenders by virtue
of any applicable Governmental Rule, the Credit Agreement, any other
Credit Document or any other agreement, all of which rights, powers,
and remedies shall be cumulative and may be exercised successively
or concurrently without impairing Agent's rights hereunder. Borrower
waives any right to require Agent or any Lender to proceed against
any Person or to exhaust any Collateral or to pursue any remedy in
Agent's or any Lender's power.

         authorities and regulatory bodies have been obtained and made and
         that all requisite taxes, levies and charges have been paid.

              (g) Borrower's Continuing Liability. Notwithstanding any
         provision of this Security Agreement or any other Credit Document or
         any exercise by Agent of any of its rights hereunder or thereunder
         (including, without limitation, any right to collect or enforce any
         Collateral), (i) Borrower shall remain liable to perform its
         obligations and duties in connection with the Collateral and (ii)
         neither Agent nor any Lender shall assume or be considered to have
         assumed any liability to perform such obligations and duties or to
         enforce any of Borrower's rights in connection with the Collateral.

              (h) Governing Law. This Security Agreement shall be governed by
         and construed in accordance with the laws of the State of California
         without reference to conflicts of law rules (except to the extent

     Agent (for the ratable benefit of the Lenders and Agent).

          [D. Pursuant to the Security Agreement, Borrower has granted to Agent
     (for the ratable benefit of the Lenders and Agent) a security interest in
     all right, title and interest of Borrower in and to the Trademarks,
     together with the goodwill of the business symbolized by the Trademarks and
     the customer lists and records related to the Trademarks and the
     applications and registrations thereof, and all proceeds thereof, including
     any and all causes of action which may exist by reason


                                    I-1[2]-1

     Security Agreement.]

          [D. Pursuant to the Security Agreement, Borrower has granted to Agent

     and all proceeds thereof, including any and all causes of action which may
     exist by reason of infringement thereof for the full term of the Copyrights

     Agreement.]

     Agreement.]

          NOW, THEREFORE, for good and valuable consideration, receipt of which
     is hereby acknowledged, Borrower does hereby further grant to Agent a

     performance and observance of the Secured Obligations.

          acquires rights in the Collateral, will be the beneficial owner
          thereof). No other Person has (or, in the case of after-acquired
          Collateral, at the time Grantor acquires rights therein, will have)
          any right, title, claim or interest (by way of Lien, purchase option
          or otherwise) in, against or to the Collateral, other than Permitted
          Liens.

               (b) Agent has (or in the case of after-acquired Collateral, at
          the time Grantor acquires rights therein, will have) a first priority
          perfected security interest in the Collateral, subject to no other
          Liens other than Permitted Liens; provided, however, that (i) the
          security interest of Agent may be subject to Permitted Liens and (ii)
          Agent must make the filings with the Patent and Trademark Office
          contemplated by this Security Agreement to perfect its security
          interest in Grantor's Patents and Trademarks registered with that
          office.

               (c) Grantor has the sole, full and unencumbered right, title and
          interest in and to (i) each of the Trademarks described in Schedule A
          to Attachment 1 hereto for the goods and services covered by the
          registrations thereof, (ii) each of the Patents described in Schedule
          B to Attachment 1 hereto, (iii) each of the Copyrights described in
          Schedule C to Attachment 1 hereto and (iv) each of the Mask Works
          described in Schedule D to Attachment 1 hereto. Any registrations for
          such Trademarks and Patents are valid and enforceable and in full
          force and effect and none of the Patents has been abandoned or
          dedicated. According to the records of the Copyright


                                     I-2-3
<PAGE>
          Office, all registered Copyrights and Mask Works are valid and
          enforceable and in full force and effect.

               (d) Grantor does not own any Patents, Trademarks, Copyrights or
          Mask Works registered in, or the subject of pending applications in,
          the Patent and Trademark Office or the Copyright Office, other than
          those described in Schedules A, B, C and D to Attachment 1 hereto.

               (e) To the best of Grantor's knowledge, no claim has been made by
          any third party and remains unresolved that any of the Patents,

          violates or may violate the rights of any Person.

               (f) Set forth in Schedule E to Attachment 1 hereto is a complete
          list of all material licenses of Patents, Trademarks, Copyrights, Mask
          Works and Trade Secrets which Grantor has granted to any Person.

          and Trade Secrets which any Person has granted to Grantor.

               (h) Grantor has obtained from each employee who may be considered
          the inventor of patentable inventions (invented within the scope of
          such employee's employment with Grantor) an agreement to assign to
          Grantor all rights to such inventions, including Patents.

               (i) Grantor has taken all commercially reasonable steps to
          protect the secrecy and the validity under applicable law of all

          4. Covenants of Grantor. Grantor hereby agrees as follows:

               (a) Grantor, at Grantor's expense, shall promptly procure,
          execute and deliver to Agent all documents, instruments and agreements
          and perform all acts which are necessary, or which Agent may
          reasonably request, to establish, maintain, preserve, protect and
          perfect the Collateral, the Lien granted to Agent therein and the
          first priority of such Lien or to enable Agent to exercise and enforce
          its rights and remedies hereunder with respect to any Collateral.
          Without limiting the generality of the preceding sentence, Grantor
          shall (i) execute all notices of security interest for each relevant
          type of intellectual property in forms suitable for filing with the
          Patent and Trademark Office or the Copyright Office, as applicable,

          forms reasonable acceptable to Agent and (ii) take all commercially
          reasonable steps in any proceeding before the Patent and Trademark
          Office, the Copyright Office or any similar office or agency in any
          other country or any


                                     I-2-4
<PAGE>
          political subdivision thereof, to diligently prosecute or maintain, as
          applicable, each application and registration of material Patents,
          Trademarks, Copyrights and Mask Works, including filing of renewals,
          affidavits of use, affidavits of incontestability and opposition,
          interference and cancellation proceedings (except to the extent that
          dedication, abandonment or invalidation is permitted hereunder or
          would not be reasonably likely to have a Material Adverse Effect).

               (b) Grantor shall not use any Collateral or permit any Collateral
          to be used in violation of (i) any provision of the Credit Agreement,
          this Security Agreement or any other Credit Document, (ii) any
          applicable Governmental Rule or Contractual Obligation where such use
          could reasonably be expected to have a Material Adverse Effect, or
          (iii) any policy of insurance covering the Collateral where such use
          is reasonably likely to have a Material Adverse Effect.

               (c) Grantor shall pay promptly when due all taxes and other
          governmental charges, all Liens and all other charges now or hereafter
          imposed upon, relating to or affecting any Collateral.

               (d) Grantor shall appear in and defend any action or proceeding
          which may affect its title to or Agent's security interest in the
          Collateral if an adverse decision is reasonably likely to have a
          Material Adverse Effect.

               (e) Grantor shall keep separate, accurate and complete records of
          the Collateral and shall permit Agent to examine and make copies of
          such records and provide such reports and information relating to the
          Collateral as Agent may reasonably request from time to time.

               (f) Grantor shall not surrender or lose possession of (other than
          to Agent), sell, encumber, lease, rent, option, license or otherwise
          dispose of or transfer any Collateral or right or interest therein
          except as permitted in the Credit Agreement, and Grantor shall keep
          the Collateral free of all Liens except Permitted Liens.

               (g) Grantor (either directly or through licensees) will make
          commercially reasonable efforts to continue to use the Trademarks
          which are material to Grantor's business or operations in connection
          with each and every trademark class of goods or services applicable to
          its current line of products or services as reflected in its current
          catalogs, brochures, price lists or similar materials in order to
          maintain such Trademarks in full force and effect free from any claim
          of abandonment for nonuse, and Grantor will not (and will not permit
          any licensee thereof to) do any act or knowingly omit to do any act
          whereby Grantor's rights in any such material Trademark is reasonably
          likely to become invalidated. Grantor will not do any act, or omit to
          do any act, whereby the Patents or Patent Registrations which are


                                     I-2-5
<PAGE>
          material to Grantor's business or operations may become abandoned or
          dedicated or the remedies available against potential infringers
          weakened if such action or omission would be reasonably likely to have
          a Material Adverse Effect and shall notify Agent immediately if it
          knows of any reason or has reason to know that any such Patent
          Registration may become abandoned or dedicated. Grantor will not do
          any act or omit to do any act, whereby the Copyrights or Mask Works
          which are material to Grantor's business or operations may become
          abandoned or dedicated or the remedies available against potential
          infringers weakened if such action or omission would be reasonably
          likely to have a Material Adverse Effect, and shall notify Agent
          immediately if it knows of any reason or has reason to know that any
          such Copyright or Mask Work may become abandoned or dedicated.

               (h) Grantor will promptly notify Agent upon the filing, either by
          Grantor or through any agent, employee, licensee or designee, of (i)
          an application for the registration of any Patent, Trademark,
          Copyright or Mask Work with the Patent and Trademark Office or the
          Copyright Office or any similar office or agency in any other country
          or any political subdivision thereof, (ii) any assignment of any
          Patent or Trademark, which Grantor may acquire from a third party,
          with the Patent and Trademark Office or any similar office or agency
          in any other country or any political subdivision thereof, or (iii)
          any assignment of any Copyright or Mask Work, which Grantor may
          acquire from a third party, with the Copyright Office or any similar
          office or agency in any other country or any political subdivision
          thereof.

               (i) Grantor shall (i) make application to the Patent and
          Trademark Office to register any material unpatented but patentable
          inventions developed by Grantor or its employees (within the scope of
          their employment), unless Grantor, in the exercise of its prudent
          business judgment, deems any such Patent not to have any significant
          commercial value or determines that its rights thereunder are better
          preserved as a Trade Secret, (ii) make application to the Patent and
          Trademark Office to register any registerable but unregistered
          material Trademarks used by Grantor in connection with its products or
          services unless Grantor in the exercise of its prudent business
          judgment, deems any such Trademark not to have any significant
          commercial value, and (iii) make application to the Copyright Office
          to register any material unregistered Copyright or Mask Work to which
          Grantor has rights unless Grantor in the exercise of its prudent
          business judgment, deems any such Copyright or Mask Work not to have
          any significant commercial value or determines that its rights
          thereunder are better protectable as a Trade Secret.

<PAGE>
               (j) Grantor shall (i) use proper statutory notice in connection
          with its use of the Trademarks, Copyrights and Mask Works, (ii)
          maintain consistent standards of quality in its manufacture of
          products sold under the Trademarks or provision of services in
          connection with the Trademarks, and (iii) take all commercially
          reasonable steps to protect the secrecy and the validity under
          applicable law of all material Trade Secrets.

               (k) If any Executive Officer of Grantor learns of any use by any
          Person of any term or design likely to cause confusion with any
          Trademark, Grantor shall promptly notify Agent of such use and of all
          steps taken and to be taken to remedy any infringement of such
          Trademark.

               (l) Grantor shall maintain with each employee who may have access
          to any material Trade Secrets of Grantor an agreement by which such
          employee agrees not to disclose such Trade Secrets and with each
          employee who may be the inventor of patentable inventions (invented
          within the scope of such employee's employment) an invention
          assignment agreement requiring such employee to assign all rights to
          such inventions, including, patents and patent applications, to
          Grantor and further requiring such employee to cooperate fully with
          Grantor, its successors in interest, including Agent, and their
          counsel, in the prosecution of any patent application or in any
          litigation involving the invention, whether such cooperation is
          required during such employee's employment with Grantor or after the
          termination of such employment.

          5. Authorized Action by Agent. Grantor hereby irrevocably appoints
     Agent as its attorney-in-fact and agrees that Agent may perform (but Agent
     shall not be obligated to and shall incur no liability to Grantor or any
     third party for failure so to do) any act which Grantor is obligated by
     this Security Agreement to perform, and to exercise such rights and powers
     as Grantor might exercise with respect to the Collateral, including,
     without limitation, the right to (a) collect by legal proceedings or
     otherwise and endorse, receive and receipt for all royalties, payments,
     proceeds and other sums and property now or hereafter payable on or on
     account of the Collateral; (b) enter into any extension, reorganization,
     deposit, merger, consolidation or other agreement pertaining to, or
     deposit, surrender, accept, hold or apply other property in exchange for
     the Collateral; (c) insure, process, preserve and enforce the Collateral;
     (d) make any compromise or settlement, and take any action it deems
     advisable, with respect to the Collateral; (e) pay any indebtedness of
     Grantor relating to the Collateral; and (f) execute UCC financing
     statements and other documents, instruments and agreements required
     hereunder; provided, however, that Agent shall exercise such powers only
     after the occurrence and during the continuance of an Event of Default. In
     furtherance of the powers granted in this paragraph 5, Grantor shall
     execute and deliver to Agent a Special Power of Attorney in the form of
     Attachment 4 hereto. Grantor agrees to reimburse Agent upon demand for all
     reasonable costs and expenses, including


                                     I-2-7
<PAGE>
     reasonable attorneys' fees, Agent may incur while acting as Grantor's
     attorney-in-fact hereunder, all of which costs and expenses are included in
     the Secured Obligations. Grantor agrees that such care as Agent gives to
     the safekeeping of its own property of like kind shall constitute
     reasonable care of the Collateral when in Agent's possession; provided,
     however, that Agent shall not be required to make any presentment, demand
     or protest, or give any notice and need not take any action to preserve any
     rights against any prior party or any other Person in connection with the
     Secured Obligations or with respect to the Collateral.

          6. Default and Remedies. Grantor shall be deemed in default under this
     Security Agreement upon the occurrence and during the continuance of an
     Event of Default, as that term is defined in the Credit Agreement. In
     addition to all other rights and remedies granted to Agent by this Security
     Agreement, the Credit Agreement, the other Credit Documents, the UCC and
     other applicable Governmental Rules, Agent may, upon the occurrence and
     during the continuance of any Event of Default, exercise any one or more of
     the following rights and remedies: (a) collect, receive, appropriate or
     realize upon the Collateral or otherwise foreclose or enforce Agent's
     security interests in any or all Collateral in any manner permitted by
     applicable Governmental Rules or in this Security Agreement; (b) notify any
     or all licensees to make payments on Receivables directly to Agent; (c)
     sell or otherwise dispose of any or all Collateral at one or more public or
     private sales, whether or not such Collateral is present at the place of
     sale, for cash or credit or future delivery, on such commercially
     reasonable terms and in such commercially reasonable manner as Agent may
     determine; (d) upon ten (10) Business Days' prior notice to Grantor, direct
     Grantor not to make any further use of the Patents, the Trademarks (or any
     mark similar thereto), the Copyrights (or any work deriving therefrom), or
     the Mask Works for any purpose; (e) upon ten (10) Business Days' prior
     notice to Grantor, license, whether general, special or otherwise, and
     whether on an exclusive or nonexclusive basis, any of the Patents,
     Trademarks, Copyrights or Mask Works, throughout the world for such term or
     terms, on such conditions, and in such manner, as Agent shall in its sole
     discretion determine; (f) enforce (and upon notice to Grantor have the
     exclusive right to enforce) against any licensee or sublicensee all rights
     and remedies of Grantor in, to and under any one or more license agreements
     with respect to the Collateral (without assuming any obligations or
     liability thereunder), and take or refrain from taking any action under any
     thereof; and (g) in addition to the foregoing, in order to implement the
     assignment, sale or other disposal of any of the Collateral, pursuant to
     the authority granted in paragraph 5 hereof, execute and deliver on behalf
     of Grantor, upon five (5) Business Days' prior notice to Grantor, one or
     more instruments of assignment of the Patents, Trademarks, Copyrights or
     Mask Works (or any application or registration thereof), in form suitable
     for filing, recording or registration in any country.

     7. Indemnification and Release.

          (a) Grantor assumes all responsibility and liability arising from the
     use of the Patents, Trademarks, Copyrights and Mask Works, and Grantor
     hereby indemnifies and holds Agent, each other Agent and each Lender and
     their respective directors, officers, employees, agents and any of their
     respective Affiliates ("Indemnitees") harmless from and against any claim,
     suit, loss, damage or expense (including reasonable attorneys' fees and
     expenses) arising out of or in connection with any alleged infringement of
     any patent, trademark, service mark, trade name, trade secret, copyright or
     mask work of a third party or alleged defect in any product manufactured,
     promoted or sold by Grantor (or any Affiliate of Grantor) in connection
     with any Patent, Trademark, Copyright or Mask Work or out of the
     manufacture, promotion, labeling, sale or advertisement of any product or
     service by Grantor (or any Affiliate of Grantor) provided, however, that
     the foregoing indemnity shall not extend to any use by Agent or any Lender
     (or any of their respective Affiliates) of any Patent, Trademark, Copyright
     or Mask Work which constitutes gross negligence or willful misconduct.
     Grantor agrees that Agent, the Agent and the Lenders do not assume, and
     shall have no responsibility for, the payment of any sums due or to become
     due under any agreement or contract included in the Collateral or the
     performance of any obligations to be performed under or with respect to any
     such agreement or contract by Grantor, and Grantor hereby agrees to
     indemnify and hold each Indemnitee harmless with respect to any and all
     claims by any Person relating thereto.

          (b) Grantor agrees to indemnify and hold the Indemnitees harmless and
     against any claim, suit, loss, damage or expense (including reasonable
     attorneys' fees and expenses) arising out of or in connection with any
     action taken or omitted to be taken by Agent hereunder with respect to any
     license agreement of Grantor, other than actions taken or omitted to be
     taken through the gross negligence or willful misconduct of such
     Indemnitees or any breach of this Agreement or the other Credit Documents.

          (c) Grantor agrees to indemnify and hold the Indemnitees harmless and
     against any claim, suit, loss, damage or expense (including reasonable
     attorneys' fees and expenses) arising out of or in connection with any
     claim, suit or proceeding instituted by Grantor or in which Grantor
     participates.

          (d) Grantor hereby releases the Indemnitees from any claims, causes of
     action and demands at any time arising out of or with respect to any
     actions taken or omitted to be taken by Agent under the powers of attorney
     granted in paragraph 5 hereof, other than actions taken or omitted


                                     I-2-9
<PAGE>
     to be taken through the gross negligence or willful misconduct of such
     Indemnitees or any breach of this Agreement or the other Credit Documents.

          (e) Grantor agrees to cause Agent to be named as an additional insured
     with respect to any policy of insurance held by Grantor from time to time
     covering product liability or intellectual property infringement risk.

          (f) Nothing contained in this Paragraph 7 shall, however, be deemed to
     require Grantor to indemnify or hold harmless any Indemnitee from any
     losses, costs, claims or damages arising from or relating to such
     Indemnitee's gross negligence or willful misconduct.

     8. Authorizations, Waivers, Etc.

          (a) Authorizations. Grantor authorizes Agent and the Lenders, in their
     discretion, without notice to Grantor, irrespective of any change in the
     financial condition of Borrower, Grantor or any other guarantor of the
     Secured Obligations since the date hereof, and without affecting or
     impairing in any way the liability of Grantor hereunder, from time to time
     to:

          accelerate or otherwise change the time for payment or performance of,

          against Borrower, Grantor, any other guarantor of the Secured
          Obligations or any security, including, without limitation, the right
          to foreclose upon any such security by judicial or nonjudicial sale;

               (xv) All rights and defenses arising out of an election of
          remedies by Agent or any Lender, even though that election of
          remedies, such as a nonjudicial foreclosure with respect to security
          for a Secured Obligation, has destroyed Grantor's rights of
          subrogation and reimbursement against Borrower by the operation of
          Section 580d of the Code of Civil Procedure or otherwise; and

               (xvi) All other rights and defenses available to Grantor by
          reason of Sections 2787 to 2855, inclusive, Section 2899 or Section
          3433 of the California Civil Code or Section 3605 of the California
          Commercial Code.

     Without limiting the scope of any of the foregoing provisions of this
     Paragraph 5, and pursuant to the provisions of California Civil Code
     Section 2856, Grantor hereby further waives all rights and defenses that
     Grantor may have because the Secured Obligations are secured by real
     property. This means, among other things:

               (A) Agent or any Lender may collect from Grantor without first
          foreclosing on any real or personal property collateral pledged by
          Borrower.

               (B) If Agent or any Lender forecloses on any real property
          collateral pledged by Borrower:

                    (1) The amount of the Secured Obligations may be reduced
               only by the price for which that collateral is sold at the
               foreclosure sale, even if the collateral is worth more than the
               sale price.

                    (2) Agent or any Lender may collect from Grantor even if
               Agent or any Lender, by foreclosing on the real property
               collateral, has destroyed any right Grantor may have to collect
               from Borrower.

     This is an unconditional and irrevocable waiver of any rights and defenses
     Grantor may have because the Secured Obligations are secured by real
     property. These rights and defenses include, but are not limited to, any
     rights or defenses based upon Section 580a, 580b, 580d, or 726 of the
     California Code of Civil Procedure.


                                     I-2-13
<PAGE>
          (c) Financial Condition of Borrower, Etc. Grantor is fully aware of
     the financial condition and affairs of Borrower. Grantor has executed this
     Security Agreement without reliance upon any representation, warranty,
     statement or information concerning Borrower furnished to Grantor by Agent
     or any Lender and has, independently and without reliance on Agent or any
     Lender, and based on such documents and information as it has deemed
     appropriate, made its own appraisal of the financial condition and affairs
     of Borrower and of other circumstances affecting the risk of nonpayment or
     nonperformance of the Secured Obligations. Grantor is in a position to
     obtain, and assumes full responsibility for obtaining, any additional
     information about the financial condition and affairs of Borrower and of
     other circumstances affecting the risk of nonpayment or nonperformance of
     the Secured Obligations and will, independently and without reliance upon
     Agent or any Lender, and based on such documents and information as it
     shall deem appropriate at the time, continue to make its own appraisals and
     decisions in taking or not taking action in connection with this Security
     Agreement.

          9. Miscellaneous.

               (a) Notices. Except as otherwise specified herein, all notices,
          requests, demands, consents, instructions or other communications to
          or upon Grantor or Agent under this Security Agreement shall be given
          as provided in Paragraph 8.01 of the Credit Agreement.

               (b) Waivers; Amendments. Any term, covenant, agreement or
          condition of this Security Agreement may be amended or waived only as
          provided in the Credit Agreement. No failure or delay by Agent in
          exercising any right hereunder shall operate as a waiver thereof or of
          any other right nor shall any single or partial exercise of any such
          right preclude any other further exercise thereof or of any other
          right. Unless otherwise specified in any such waiver or consent, a
          waiver or consent given hereunder shall be effective only in the
          specific instance and for the specific purpose for which given.

               (c) Successors and Assigns. This Security Agreement shall be
          binding upon and inure to the benefit of Agent, Grantor and the
          Lenders and their respective successors and assigns; provided,
          however, that Agent, the Lenders and Grantor may sell, assign and
          delegate their respective rights and obligations hereunder only as
          permitted by the Credit Agreement. The Lenders and Agent may disclose
          this Security Agreement as provided in the Credit Agreement.

               (d) Partial Invalidity. If at any time any provision of this
          Security Agreement is or becomes illegal, invalid or unenforceable in
          any respect under the law of any jurisdiction, neither the legality,
          validity or enforceability of the remaining provisions of this
          Security Agreement nor the


                                     I-2-14
<PAGE>
          legality, validity or enforceability of such provision under the law
          of any other jurisdiction shall in any way be affected or impaired
          thereby.

               (e) Cumulative Rights, etc. The rights, powers and remedies of
          Agent under this Security Agreement shall be in addition to all
          rights, powers and remedies given to Agent and the Lenders by virtue
          of any applicable Governmental Rule, the Credit Agreement, any other
          Credit Document or any other agreement, all of which rights, powers,
          and remedies shall be cumulative and may be exercised successively or
          concurrently without impairing Agent's rights hereunder. Grantor
          waives any right to require Agent or any Lender to proceed against any
          Person or to exhaust any Collateral or to pursue any remedy in Agent's
          or any Lender's power.

               (f) Payments Free of Taxes, Etc. All payments made by Grantor
          under this Security Agreement shall be made by Grantor free and clear
          of and without deduction for any and all present and future taxes,
          levies, charges, deductions and withholdings. In addition, Grantor
          shall pay upon demand any stamp or other taxes, levies or charges of
          any jurisdiction with respect to the execution, delivery,
          registration, performance and enforcement of this Security Agreement.
          Upon request by Agent, Grantor shall furnish evidence satisfactory to
          Agent that all requisite authorizations and approvals by, and notices
          to and filings with, governmental authorities and regulatory bodies
          have been obtained and made and that all requisite taxes, levies and
          charges have been paid.

               (g) Grantor's Continuing Liability. Notwithstanding any provision
          of this Security Agreement or any other Credit Document or any
          exercise by Agent of any of its rights hereunder or thereunder
          (including, without limitation, any right to collect or enforce any
          Collateral), (i) Grantor shall remain liable to perform its
          obligations and duties in connection with the Collateral and (ii)
          neither Agent nor any Lender shall assume or be considered to have
          assumed any liability to perform such obligations and duties or to
          enforce any of Grantor's rights in connection with the Collateral.

               (h) Governing Law. This Security Agreement shall be governed by
          and construed in accordance with the laws of the State of California
          without reference to conflicts of law rules (except to the extent
          otherwise provided in the UCC).

               (b) Agent has (or in the case of after-acquired Collateral, at
          the time Borrower acquires rights therein, will have) a first priority
          perfected security interest in the Pledged Shares and the other
          Collateral.

               (c) All Pledged Shares have been (or in the case of
          after-acquired Pledged Shares, at the time Borrower acquires rights
          therein, will have been) duly authorized, validly issued and fully
          paid and are (or in the case of after-acquired Pledged Shares, at the
          time Borrower acquires rights therein, will be) non-assessable.

               (d) Borrower has (or will have within fourteen (14) days of the
          date hereof) delivered to Agent, together with all necessary stock
          powers, endorsements, assignments and other necessary instruments of
          transfer, the originals of all Pledged Shares, other certificated
          securities, other Collateral and all certificates, instruments and
          other writings evidencing the same.

               (e) Set forth in Attachment 1 hereto is a true, complete and
          accurate list of all Subsidiary Shares. All information set forth in
          Attachment 1 is true, complete and accurate.

          4. Covenants. Borrower hereby agrees as follows:

               (a) Borrower, at Borrower's expense, shall promptly procure,
          execute and deliver to Agent all documents, instruments and agreements
          and perform all acts which are necessary, or which Agent may
          reasonably request, to establish, maintain, preserve, protect and
          perfect the Collateral, the Lien granted to Agent therein and the
          first priority of such Lien or to enable Agent to exercise and enforce
          its rights and remedies hereunder with respect to any Collateral.
          Without limiting the generality of the preceding sentence, Borrower
          shall (i) procure, execute and deliver to Agent all stock powers,
          endorsements, assignments, financing statements and other instruments
          of transfer requested by Agent, (ii) deliver to Agent promptly upon
          receipt the originals of all Pledged Shares, other certificated
          securities, other Collateral and all certificates, instruments and
          other writings evidencing the same and (iii) cause the Lien of Agent
          to be recorded or registered in the books of any financial
          intermediary or clearing corporation requested by Agent.

               (b) Borrower shall pay promptly when due all taxes and other
          governmental charges, all Liens and all other charges now or hereafter
          imposed upon, relating to or affecting any Collateral.

               (c) Upon demand by Agent after the occurrence and during the
          continuation of any Event of Default, Borrower shall deposit, or cause
          to be deposited, all remittances, checks and other funds (in whatever
          form) received with respect to Collateral to a deposit account for
          which Borrower


                                      J-4
<PAGE>
          has complied with subparagraph 4(e) of the Borrower Security Agreement
          and in which Agent has a first priority perfected security interest.

               (d) Borrower shall appear in and defend any action or proceeding
          which may affect its title to or Agent's security interest in the
          Collateral if an adverse decision is reasonably likely to have a
          Material Adverse Effect.

               (e) Borrower shall not surrender or lose possession of (other
          than to Agent), sell, encumber, lease, rent, option, or otherwise
          dispose of or transfer any Collateral or right or interest therein
          except as permitted in the Credit Agreement, and, notwithstanding any
          provision of the Credit Agreement, Borrower shall keep the Collateral
          free of all Liens (except with respect to Collateral other than the
          Pledged Shares, Permitted Liens.

          5. Voting Rights and Dividends Prior to Default. Unless an Event of
     Default has occurred and is continuing:

               (a) Borrower may exercise or refrain from exercising any and all
          voting and other consensual rights pertaining to the Pledged Shares or
          any part thereof; provided, however, that Borrower shall not exercise
          or refrain from exercising any such rights where the consequence of
          such action or inaction would be (i) to impair any Collateral, the
          Lien granted to Agent therein, the first priority of such Lien or
          Agent's rights and remedies hereunder with respect to any Collateral
          or (ii) otherwise inconsistent with the terms of this Pledge Agreement
          and the other Credit Documents.

               (b) Borrower may receive and retain all dividends and interest
          paid in cash in respect of the Pledged Shares, except for any such
          dividends and interest paid in connection with a partial or total
          liquidation or dissolution or in connection with a reduction of
          capital, capital surplus or paid-in-surplus. Borrower shall promptly
          deliver to Agent to hold as Collateral all dividends and interest
          which Borrower is not entitled to receive and retain pursuant to the
          preceding sentence, in the same form as so received (with any
          necessary endorsement), and, until so delivered, shall hold such
          dividends and interest in trust for the benefit of Agent, segregated
          from the other property or funds of Borrower.

          6. Authorized Action by Agent. Borrower hereby irrevocably appoints
     Agent as its attorney-in-fact and agrees that Agent may perform (but Agent
     shall not be obligated to and shall incur no liability to Borrower or any
     third party for failure so to do) any act which Borrower is obligated by
     this Pledge Agreement to perform, and to exercise such rights and powers as
     Borrower might exercise with respect to the Collateral, including, without
     limitation, the right to (a) collect by legal proceedings or otherwise and
     endorse, receive and receipt for all dividends, interest, payments,
     proceeds and other sums and property now or hereafter payable on or on
     account of the Collateral; (b) enter into any extension, reorganization,


                                      J-5
<PAGE>
     deposit, merger, consolidation or other agreement pertaining to, or
     deposit, surrender, accept, hold or apply other property in exchange for
     the Collateral; (c) insure, process, preserve and enforce the Collateral;
     (d) make any compromise or settlement, and take any action it deems
     advisable, with respect to the Collateral; (e) pay any Indebtedness of
     Borrower relating to the Collateral; and (f) execute UCC financing
     statements and other documents, instruments and agreements required
     hereunder; provided, however, that Agent may exercise such powers only
     after the occurrence and during the continuance of an Event of Default.
     Borrower agrees to reimburse Agent upon demand for all reasonable costs and
     expenses, including attorneys' fees, Agent may incur while acting as
     Borrower's attorney-in-fact hereunder, all of which costs and expenses are
     included in the Secured Obligations. Borrower agrees that such care as
     Agent gives to the safekeeping of its own property of like kind shall
     constitute reasonable care of the Collateral when in Agent's possession;
     provided, however, that Agent shall not be required to make any
     presentment, demand or protest, or give any notice and need not take any
     action to preserve any rights against any prior party or any other Person
     in connection with the Secured Obligations or with respect to the
     Collateral.

          7. Events of Default.

               (a) Event of Default. Borrower shall be deemed in default under
          this Pledge Agreement upon the occurrence and during the continuance
          of an Event of Default, as that term is defined in the Credit
          Agreement.

               (b) Voting Rights and Dividends. Upon the occurrence and during
          the continuance of an Event of Default:

                    (i) All rights of Borrower to exercise the voting and other
               consensual rights which it would otherwise be entitled to
               exercise pursuant to subparagraph 5(b) hereof and to receive the
               dividends and interest payments which it would otherwise be
               authorized to receive and retain pursuant to subparagraph 5(a)
               hereof shall cease and all such rights shall thereupon become
               vested in Agent which shall thereupon have the sole right, but
               not the obligation, to exercise such voting and other consensual
               rights and to receive and hold as Collateral such dividends and
               interest payments.

                    (ii) Borrower shall promptly deliver to Agent to hold as
               Collateral all dividends and interest received by Borrower after
               the occurrence and during the continuance of any Event of
               Default, in the same form as so received (with any necessary
               endorsement), and, until so delivered, shall hold such dividends
               and interest in trust for the benefit of Agent, segregated from
               the other property or funds of Borrower.


                                      J-6
<PAGE>
               (c) Other Rights and Remedies. In addition to all other rights
          and remedies granted to Agent by this Pledge Agreement, the Credit
          Agreement, the other Credit Documents, the UCC and other applicable
          Governmental Rules, Agent may, upon the occurrence and during the
          continuance of any Event of Default, exercise any one or more of the
          following rights and remedies: (i) collect, receive, appropriate or
          realize upon the Collateral or otherwise foreclose or enforce Agent's
          security interests in any or all Collateral in any manner permitted by
          applicable Governmental Rules or in this Pledge Agreement; (ii) notify
          any or all issuers of or transfer or paying agents for the Collateral
          or any applicable clearing corporation, financial intermediary or
          other Person to register the Collateral in the name of Agent or its
          nominee and/or to pay all dividends, interest and other amounts
          payable in respect of the Collateral directly to Agent; (iii) sell or
          otherwise dispose of any or all Collateral at one or more public or
          private sales, whether or not such Collateral is present at the place
          of sale, for cash or credit or future delivery, on such terms and in
          such manner as Agent may determine; and (iv) require Borrower to
          assemble all records and information relating to the Collateral and
          make it available to Agent at a place to be designated by Agent. In
          any case where notice of any sale or disposition of any Collateral is
          required, Borrower hereby agrees that seven (7) days notice of such
          sale or disposition is reasonable.

               (d) Securities Laws.

                    (i) Borrower acknowledges and recognizes that Agent may be
               unable to effect a public sale of all or a part of the Pledged
               Shares and may be compelled to resort to one or more private
               sales to a restricted group of purchasers who will be obligated
               to agree, among other things, to acquire the Pledged Shares for
               their own account, for investment and not with a view to the
               distribution or resale thereof. Borrower acknowledges that any
               such private sales may be at prices and on terms less favorable
               to Agent than those of public sales, and agrees that such private
               sales shall be deemed to have been made in a commercially
               reasonable manner and that Agent has no obligation to delay sale
               of any Pledged Shares to permit the issuer thereof to register it
               for public sale under the Securities Act of 1933, as amended, or
               under any state securities law.

                    (ii) Upon the occurrence and during the continuation of an
               Event of Default and at Agent's request, Borrower shall, and
               shall cause all issuers of Collateral and all officers and
               directors thereof and all other necessary Persons to, execute and
               deliver all documents, instruments and agreements and perform all
               other acts necessary or, in the opinion of Agent, advisable to
               sell the Collateral in any public or private sale, including any
               acts requested by Agent to (A) register


                                      J-7
<PAGE>
               any Collateral under the Securities Act of 1933, (B) qualify any
               Collateral under any state securities or "Blue Sky" laws or (C)
               otherwise permit any such sale to be made in full compliance with
               all applicable Governmental Rules.

          8. Miscellaneous.

               (a) Notices. Except as otherwise specified herein, all notices,
          requests, demands, consents, instructions or other communications to
          or upon Borrower or Agent under this Pledge Agreement shall be given
          as provided in Paragraph 8.01 of the Credit Agreement.

               (b) Waivers; Amendments. Any term, covenant, agreement or
          condition of this Pledge Agreement may be amended or waived only as
          provided in the Credit Agreement. No failure or delay by Agent or any
          Lender in exercising any right hereunder shall operate as a waiver
          thereof or of any other right nor shall any single or partial exercise
          of any such right preclude any other further exercise thereof or of
          any other right. Unless otherwise specified in any such waiver or
          consent, a waiver or consent given hereunder shall be effective only
          in the specific instance and for the specific purpose for which given.

               (c) Successors and Assigns. This Pledge Agreement shall be
          binding upon and inure to the benefit of Agent, the Lenders and
          Borrower and their respective successors and assigns; provided,
          however, that Agent, the Lenders and Borrower may sell, assign and
          delegate their respective rights and obligations hereunder only as
          permitted by the Credit Agreement. Agent may disclose this Pledge
          Agreement as provided in the Credit Agreement.

               (d) Partial Invalidity. If at any time any provision of this
          Pledge Agreement is or becomes illegal, invalid or unenforceable in
          any respect under the law of any jurisdiction, neither the legality,
          validity or enforceability of the remaining provisions of this Pledge
          Agreement nor the legality, validity or enforceability of such
          provision under the law of any other jurisdiction shall in any way be
          affected or impaired thereby.

               (e) Cumulative Rights, etc. The rights, powers and remedies of
          Agent and the Lenders under this Pledge Agreement shall be in addition
          to all rights, powers and remedies given to Agent and the Lenders by
          virtue of any applicable Governmental Rule, the Credit Agreement, any
          other Credit Document or any other agreement, all of which rights,
          powers, and remedies shall be cumulative and may be exercised
          successively or concurrently without impairing Agent's rights
          hereunder. Borrower waives any right to require Agent or any Lender to
          proceed against any Person or to exhaust any Collateral or to pursue
          any remedy in Agent's or such Lender's power.


                                      J-8
<PAGE>
               (f) Payments Free of Taxes, Etc. All payments made by Borrower
          under this Pledge Agreement shall be made by Borrower free and clear
          of and without deduction for any and all present and future taxes,
          levies, charges, deductions and withholdings. In addition, Borrower
          shall pay upon demand any stamp or other taxes, levies or charges of
          any jurisdiction with respect to the execution, delivery,
          registration, performance and enforcement of this Pledge Agreement.
          Upon request by Agent, Borrower shall furnish evidence satisfactory to
          Agent that all requisite authorizations and approvals by, and notices
          to and filings with, governmental authorities and regulatory bodies
          have been obtained and made and that all requisite taxes, levies and
          charges have been paid.

               (g) Borrower's Continuing Liability. Notwithstanding any
          provision of this Pledge Agreement or any other Credit Document or any
          exercise by Agent of any of its rights hereunder or thereunder
          (including, without limitation, any right to collect or enforce any
          Collateral), (i) Borrower shall remain liable to perform its
          obligations and duties in connection with the Collateral and (ii)
          neither Agent nor any Lender shall assume or be considered to have
          assumed any liability to perform such obligations and duties or to
          enforce any of Borrower's rights in connection with the Collateral.

               (h) Governing Law. This Pledge Agreement shall be governed by and
          construed in accordance with the laws of the State of California
          without reference to conflicts of law rules (except to the extent
          otherwise provided in the UCC).

               (b) In respect of the interests of Agent in the policies, the

          Insured Party or by any Person having temporary possession of the
          property covered thereby (the "Property") while under contract with
          any Insured Party to perform maintenance, repair, alteration or
          similar work on the Property, and shall insure the interests of Agent
          regardless of any breach or violation of any warranty, declaration or
          condition contained in the insurance policy by any Insured Party or
          Agent or any other additional insured (other than by such additional
          insured, as to such additional insured) or by any Person having
          temporary possession of the Property while under contract with
          Borrower to perform maintenance, repair, alteration or similar work on
          the Property.

               (c) If the insurance policy is cancelled for any reason
          whatsoever, or substantial change is made in the coverage that affects
          the interests of Agent, or if the insurance coverage is allowed to
          lapse for non-payment of premium, such cancellation, change or lapse
          shall not be effective as to Agent for 30 days (or 10 days in the case
          of non-payment of premium) after receipt by Agent of written notice
          from the insurers of such cancellation, change or lapse.

               (d) Neither Agent nor any Lender shall have any obligation or
          liability for premiums, commissions, assessments, or calls in
          connection with the insurance.

          or any other deduction, whether by attachment or otherwise, that it
          may have against Agent and each Lender.

               (f) The insurance shall be primary without right of contribution
          from any other insurance that may be carried by Agent or any Lender
          with respect to its or their interest in the Property.

               (g) The insurer shall waive any right of subrogation against
          Agent and each Lender.

<PAGE>
               (h) All provisions of the insurance, except the limits of

          Insured Party or by any Person having temporary possession of the
          property covered thereby (the "Property") while under contract with
          any Insured Party to perform maintenance, repair, alteration or
          similar work on the Property, and shall insure the interests of Agent
          regardless of any breach or violation of any warranty, declaration or
          condition contained in the insurance policy by any Insured Party or
          Agent or any other additional insured (other than by such additional
          insured, as to such additional insured) or by any Person having
          temporary possession of the Property while under contract with
          Borrower to perform maintenance, repair, alteration or similar work on
          the Property; provided, however, that the foregoing shall not be
          deemed to (i) cause such insurance policies to cover matters otherwise
          excluded from coverage by the terms of such policies or (ii) require
          any insurance to remain in force notwithstanding non-payment of
          premiums except as provided in clause (c) below.

               (c) If the insurance policy is cancelled for any reason
          whatsoever, or substantial change is made in the coverage that affects
          the interests of Agent, or if the insurance coverage is allowed to
          lapse for non-payment of premium, such cancellation, change or lapse

          of non-payment of premium) after receipt by Agent of written notice
          from the insurer of such cancellation, change or lapse.

               (d) Neither Agent nor any Lender shall have any obligation or
          liability for premiums, commissions, assessments, or calls in
          connection with the insurance.

          from any other insurance that may be carried by Agent or any Lender
          with respect to their interests in the Property.
