NETWORKING PRODUCTS

Overview

  The computer networking industry represents one of the fastest growing
segments of the technology industry. Industry growth has been a product of a
rising number of personal computers in use within organizations, generational
upgrades of computers, standardization of network operating system software, the
rising importance of network communications as an organizational productivity
tool and the increasing speed and flexibility of networks. According to
International Data Corporation ("IDC"), in 1996 there are an estimated 189
million PCs installed in businesses worldwide and 118 million PCs, or 62%, are
connected to LANs. By 1999, the installed base of business PCs is projected to
rise to 290 million, of which 220 million, or 76%, are expected to be connected
to a network.

  Local area networks connect groups of personal computers, file servers,
printers and other devices, thereby facilitating communications among those
devices. The following is a brief description of the principal components of a
LAN:

  Adapter cards. Most LANs utilize one of two generally accepted networking
topologies: Ethernet (approximately 80% of networks, according to IDC) or Token
Ring (approximately 20%). Generally, Ethernet LANs transmit data over a network
at 10 megabits per second ("Mb" or "Mbps"); Token Ring LANs generally operate at
4 or 16Mbps. A new standard called Fast Ethernet (also called 10/100 Ethernet or
100BaseT) transmits data at 100Mbps. For any PC connected to a network there is
a need for a LAN adapter card, which translates data to and from the computer in
a format understandable to the network. The adapter card must conform to the LAN
topology (Ethernet, Fast Ethernet, or Token Ring), to the internal architecture
of the PC (the 16-bit ISA bus or 32-bit PCI and EISA buses), the physical
dimensions of the PC (such as the credit-card-sized PCMCIA adapter cards
required for laptop computers), and to the physical wiring scheme of the network
(there are three commonly used wiring systems, the most popular one of which is
called 10BaseT). As such, there are numerous permutations of adapter cards
required to meet the needs of network users, and differentiating features that
further segment the market. Microdyne designs, manufactures, markets, and sells
each of the adapter cards described above.

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

  Concentrators and hubs. In addition, small groups of networked PCs are linked
by devices called concentrators or unmanaged hubs, which control data traffic
within a small group of PCs. Concentrators generally do not have on-board
microprocessors to provide "intelligence" to the data switching process. Hubs
that have such built-in microprocessors are generally called "managed" hubs and
can handle more PCs and peripherals at higher data rates. Microdyne markets and
sells concentrators and unmanaged hubs.

  File server and printer adapter cards. Hubs and concentrators are, in turn,
connected to file servers and printers, each of which also requires a
specialized adapter card linking the device to the network. File servers may
also have links to redundant storage devices to ensure against loss of data in
the event of a catastrophic failure of the file server; such links require
specialized adapter cards at each device called mirrored server links. Microdyne
designs, manufactures, markets and sells file server adapter cards, and markets
and sells print servers and mirrored server link hardware.

  Switches. Beyond a certain size, LANs experience congestion as too many users
vie for the available bandwidth of the network. To accomodate the needs of
larger organizations, LANs of either the same or different topologies can be
connected by switches, which route inter-computer traffic among different LANs.
Microdyne markets and sells several configurations of LAN switches connecting
Ethernet to Ethernet, Fast Ethernet to Fast Ethernet, and Ethernet to Fast
Ethernet.

  Other adapter cards. Minicomputers and mainframe computers may also reside on
a LAN and such connections require adapter cards specific to the operating
system of each larger computer. Microdyne designs, manufactures, markets and
sells minicomputer and mainframe computer adapter cards.

  Other networking products. Contiguous or non-contiguous LANs are connected
together via routers, which are devices that provide protocol translation and,
literally, "route" data traffic between networks. Microdyne does not offer such
products, which are generally considered wide-area-networking devices.

The changing role of networks

  Networks have become an essential element of organizational productivity.
Initially, LANs performed simple file and print sharing tasks among a group of
PC users. As a result of faster processing capabilities of PCs, inexpensive,
more powerful mass storage file and application servers, generally falling
hardware prices and faster network speeds, LANs are now used to also deliver
critical applications among network users. These new applications include fax
origination and delivery, e-mail access, document imaging, storage and
manipulation, desktop video conferencing, real-time workgroup use of common
images and other CPU-intensive networking activities. As user requirements for
the network have increased -- including the need for greater throughput speeds
and bandwidth -new bus architectures, network topologies and transmission media
have been developed. The resulting upgrade and sale of new PCs, adapter cards
and ancillary networking hardware to the installed base have further stimulated
market growth.

  The Internet and its graphical adjunct, the World-Wide Web, have contributed
to the explosive growth of PCs both in business and at home. At-home users
generally connect to the Internet via a modem and a telephone line (a connection
scheme which does not utilize any Microdyne products). Computer users within an
organization may also access the Internet via a modem and a dedicated telephone
line but, more likely, the organization maintains a direct connection to an
Internet Service Provider from one or more points on the organization's LAN. In
that case, PC users who wish to connect to the Internet or the World Wide Web do
so via their LAN, and Microdyne's adapter cards, hubs, and switches become an
integral part of the connection process.

  Within the past year, the concept of the intranet has taken hold. An intranet
is a collection of interconnected local area networks within an organization, in
which a file server is designated as the internal organization's equivalent of a
"home page" for employees and others with access to it. Connecting to an
intranet is the same as accessing any other file server on a LAN. Microdyne's
adapter cards, hubs, and switches are an integral aspect of intranet
connectivity.

  LAN usage has expanded from a group of physically proximate users connected by
wires to include remote users requiring periodic access to certain computers and
file servers. The growth of laptop and notebook PCs, combined with improved
modem technology, higher transmission speeds, falling telecommunications costs
and growth in online services and the Internet, have fueled demand for remote
access to and from networks. Remote access allows users to dial-in to LANs from
remote sites and to access external networks (e.g., Compuserve, Lexis/Nexis, the
Internet) via their office PC without the requirement of a dedicated telephone
line or modem. Remote access requires specialized software and board- or system-

level hardware. Microdyne designs, manufactures, markets and sells board- and
system-level remote access hardware.

The networking environment

  The Company believes that as LANs have evolved, many segments of local area
networking have become non-proprietary, price sensitivity has increased and
buyers have come to favor multi-product vendors. In addition, buyers have become
more cautious about embracing new technology if adopting it renders a large part
of an existing networking investment obsolete. As a result, the Company believes
that an ability to differentiate products through enhancements and added
features, the timing of product introductions, effective distribution and
marketing, efficient manufacturing and a low-cost infrastructure are critical
elements for success.

  The Company has established itself as a leading supplier of LAN adapter cards
which provide the essential connection between computers (including personal
computers, file servers, minicomputers and mainframe computers) and the network.
The Company's products support all established computer bus structures, wiring
systems and network topologies, including Ethernet, Fast Ethernet and Token
Ring. The Company also sells a line of products directed to the remote access
market permitting both dial-up access to LANs and LAN access to remote
databases. The Company believes that its products provide a combination of
reliable, high performance, fully featured solutions at attractive prices.

  To enhance its competitiveness, Microdyne offers a broad mix of networking
products that meet both the broad needs of those who build and maintain
networks, as well as specialty products that occupy niches within the networking
market. Microdyne's product family consists of more than 100 individual products
grouped into the principal categories of Fast Ethernet, Ethernet, and Token Ring
adapter cards, hubs, and switches; remote access products; wide-area and IBM
connectivity products; and minicomputer connectivity. Microdyne also sells
Bundled Products consisting of Microdyne hardware packaged with Novell Inc.'s
("Novell") NetWare. The Company leverages Novell's position as the largest
supplier of LAN operating system software through a perpetual, exclusive right
to distribute certain networking products using Novell trade dress. Microdyne
also sells products under the Eagle and EP brands.

Distribution

  Products of the kind sold by Microdyne's Networking Products Division are
generally sold in one of three ways: The first is via direct sale to large
end-user organizations by bid. Generally, except for sales to the U.S.
Government via GSA schedules, Microdyne does not sell to such organizations. The
second method is to sell products directly to very large system integrators,
which install PCs and networks for clients. Generally, Microdyne does not sell
to such system integrators. These two channels of distribution are characterized
by intense marketing efforts. The third channel of distribution, described more
fully below, is the two-step distribution channel. According to IDC, this
channel accounted for more than 75% of all networking products sold in the
United States in 1994.

  The two-step distribution process consists of distributors and resellers.
Electronics distributors stock products from hundreds of manufacturers. The
industry includes several hundred distributors specializing in computer products
and these firms serve regional, national or international markets. Microdyne's
largest distributors include Ingram Micro Corporation, Southern Electronics
Corporation, Tech Data, Inc., Merisel Inc. and C2000 GmbH. The customers of
those distributors are, in turn, more than 50,000 worldwide computer products
value-added resellers ("VARs") which sell to smaller systems integrators that
specify, assemble and install networks for end user customers; and integrators,
which install components and systems as a service to customers. The Company
believes that selling through distributors carries specific benefits, including
limiting the Company's customers to a finite number of generally well-financed
entities, limiting the amount of finished-goods inventory which the Company must
carry and lessening the need for a direct sales force.

  Microdyne treats sales to distributors outside the United States (or
U.S.-based distributors with a majority of their sales in international markets)
in a manner substantially similar to U.S.-based accounts. All products are
priced to distributors in U.S. dollars, and distributors assume any risk of 
currency fluctuation.

  Because Microdyne reports revenue based upon sale of products to distributors,
which in turn are not the final customers for products, the Company places
considerable emphasis on tracking the sale of products from distributors to
resellers, VARs, and integrators. The quality of such sales information (called
"POS," for Point of Sale data) varies widely among distributors. POS from the
largest, U.S.-based distributors is

available weekly and, although subject to revision, is generally accurate.
During the past year, Microdyne has invested in creating active programs to
obtain and interpret POS data from all distributors in all locations.

Extended Distribution Program; Novell Agreements

  Beginning in 1993, Microdyne broadened its distribution network by adding a
second group of distributors for which Microdyne served as a source of both
networking hardware products and Novell NetWare network operating system
software. Microdyne combined its networking hardware products with appropriate
Novell NetWare in one package. The resulting combinations (called "Bundled
Products" beginning in 1994) were sold under the Extended Distribution Program.
Pursuant to an agreement with Novell, Microdyne sought out distributors that
were not otherwise authorized by Novell to sell NetWare and other Novell
software products. Distribution terms and discount policies were set by Novell.
The Company believed that by participating in the Extended Distribution Program,
Microdyne enhanced its position as a supplier of networking hardware products
and increased the likelihood that its products would be recommended by these
distributors. Sales rose rapidly through the end of 1995, but declined after the
first quarter of FY1996 as Novell decreased the discount available to Microdyne
for the purchase of NetWare, making the sale of Bundled Products less
attractive, and altered its distribution policies and practices.

   In April, 1996, Microdyne obtained the perpetual, exclusive,
non-royalty-bearing rights to market a series of hardware products in Novell
trade dress, in return for a payment of $6.8 million in cash and notes. The
April 1996 agreement superceded an earlier series of agreements between the two
companies, signed between 1989 and 1995, under which the Company manufactured
and distributed various networking products utilizing Novell licensed technology
and trade dress. Those agreements, which required Microdyne to pay a royalty
based on sales into distribution, reserved to Novell the right to grant
identical rights to other manufacturers and to terminate Microdyne's rights at
any time. Microdyne paid $6.4 million of royalties under those earlier
agreements in FY1995.

Marketing, Sales and Customer Support

  Because there are several levels of intermediaries between the Company and its
end user customer, Microdyne devotes its sales resources to working with
distributors ("push" programs) and must rely upon marketing efforts to reach
resellers and end user customers ("pull" programs). It is critical to the
Company's success that distributors' telemarketing representatives are familiar
with Microdyne's products and can explain to their customers how Microdyne
products are differentiated from those of its competitors. To that end, the
Company conducts periodic training programs for its distributors' telemarketing
representatives. The Company may also periodically run push programs including
promotions and rebates aimed at distributors' telemarketing representatives.

  The Company's pull programs are aimed at resellers and end users. These
programs take the form of print advertising in computer industry trade
publications that reach resellers and corporate information systems managers,
direct mail to resellers, trade press publicity about new products and product
features, participation in the networking industry's trade shows, promotions
designed to increase sales in a specific period, and rebates.

  The Company uses its Novell and Eagle brand names to establish and retain
customer loyalty to Microdyne's products. Microdyne believes the Novell name
connotes quality and reliability in the minds of customers, and that the Eagle
name is well established in the minds of many customers as a reliable,
price-competitive brand.

  As part of the Company's acquisition of the IRMAtrac product line, Attachmate
assumed certain obligations for the continued sale of those products for a
period of five years commencing in 1994. Microdyne is dependent upon
Attachmate's efforts for the sale of Token Ring products.

  Microdyne maintains a toll-free telephone technical support center in
Alexandria, Virginia and San Jose, California where help is available 12 hours a
day, five days a week. Networking products have a lifetime warranty against 
failure or defective workmanship. Products are replaced upon submission of 
the failed product together with purchase documentation.

Research and Development

  Research and development activities are carried out at the Company's facility
in San Jose, California by a staff of approximately 30 engineers. Research and
development expense in fiscal 1996 declined slightly to $3.5 million from $3.8
million in fiscal 1995. Expenditures for research and development in the
Networking Products Division was $2.3 million in 1994. Certain software
development expenses are capitalized, the amortization of which is included as
part of "Amortization of Intangibles" in the Consolidated Statements of
Operations.

  The Company focuses its engineering efforts on product cost reduction,
extension of existing product lines and enrichment of features on existing
products. The Company has historically obtained new technologies or new products
primarily through OEM relationships or the purchase of technology as part of
larger business acquisitions. Each of the four acquisitions completed between
July 1994 and September 1995 contributed specific new products and/or
technologies to Microdyne.

Manufacturing and Supply

  Because of variable demand for its products and the availability of low-cost
contract production capabilities, Microdyne outsources virtually all of its
board-level Networking Products manufacturing to contract manufacturers, which
are primarily established, U.S.-based corporations. The Company believes it can
maintain a high level of quality while reducing its cost of goods sold below
that which the Company would incur if it manufactured products in-house. The
Company believes there are a sufficient number of contract manufacturers to
ensure adequacy of supply for the foreseeable future. Microdyne has experienced
no substantial difficulty purchasing components and raw materials in the open
market from multiple suppliers; however, certain integrated circuits are
available from a single vendor and can require long lead times to obtain in
quantity.

Competition

  The networking products market is very competitive. The Company believes its
ability to compete successfully depends on a number of factors, including:
price; product features; product quality; performance and reliability; name
recognition and reputation; international certification; retention of
experienced sales, marketing and service personnel; development of new products
and enhancements; and adherence to rapidly changing industry standards.

  Microdyne competes with a number of vendors including 3Com Corporation,
Standard Microsystems Corporation and Intel Corporation. Each has significantly
greater financial, marketing, technical and other resources as well as the
capacity to obtain components at lower cost either by purchasing large
quantities of such components or by fabricating such components in-house. These
competitors have the financial resources to lower prices in order to increase
market share, and may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, devote greater resources to
the development, promotion and sale of their products or control the timing of,
or respond more effectively to, new product introductions.

AEROSPACE TELEMETRY

Overview

  Data gathering and analysis is a basic requirement in the testing and analysis
of any process or operation. When the process or device being measured is close
at hand, it is a relatively simple task to attach probes, sensors or other
measuring devices to the object. These devices convert physical measurements
(e.g., temperature, rotation, pressure) into a variable stream of electrical
current. The current flows over wires and is either shown on an analog display
(a thermometer or voltmeter, for example) or converted into digital form and fed
into a computer file. This well-established practice works well so long as the
object or process to be measured is sufficiently close to permit wires to
connect those probes and sensors with the computer logging the resulting output.

  Telemetry is the technology of measuring various equipment performance
parameters at a distance, and is required when the object under test is moving
too quickly or is at too great a distance to use wires. Information may consist
of readings from hundreds of sensors recording such things as heat, vibration,
stress and operational performance. Each sensor will produce its own data stream
which must be transmitted and captured. In telemetry, data is gathered,
multiplexed, and transmitted at microwave frequencies, usually

in a rapid burst form, toward a ground station. There, a highly selective radio
receiver gathers the information. In other applications such as weather
satellites or space vehicles, the information will consist of data and video
transmissions. The U.S. Government operates several hundred ground stations,
each of which may have racks of telemetry receivers. Other governments operates
dozens of sites.

  Since 1968, Microdyne has manufactured telemetry receivers, sophisticated
radio receivers that can accurately tune in and hold the telemetry signals from
aircraft and space vehicles. During the past several years, Microdyne has
expanded and updated its telemetry product line, including the addition of
card-level products that perform essentially the same functions as the Company's
traditional rack-mounted devices. While there is and will continue to be a
substantial market for stand-alone rack-mounted products, two trends are pushing
telemetry receivers toward becoming board-level systems with computer control.
First, very powerful personal computers can process telemetry data at rates
previously unattainable. Second, telemetry receivers are increasingly being used
in mobile environments such as aircraft and on board ships where the receivers'
light weight and compactness are an advantage over larger rack mounted devices.
The Company's new telemetry products include:

    - A single-card telemetry receiver designed to plug into a VME,
      VXI or PC bus; and

    - A board-level diversity combiner which is a special device to take the
      input of two telemetry receivers, each of which has been tuned to the same
      sets of frequencies, but at different polarity, and combine those two
      signal streams into one continuously readable data stream. This type of
      product is required whenever the telemetry stream comes from a vehicle
      that is maneuvering or rotating.

  Other Aerospace Telemetry products include compact telemetry receivers and a
sophisticated signal simulation source for use in calibrating telemetry
equipment and systems, to ensure that a system is set up correctly and fully
operational prior to a mission; and diversity combiners that allow data loggers
to record an uninterrupted stream of data from two receivers, regardless of the
polarity of the signal from the telemetry source.

  The Company has long been a supplier of telemetry receivers to system
integrators both in the U.S. market and internationally. Since 1989, Microdyne
has actively bid on systems contracts in the $500,000 - $15 million range.

  The growth of the Aerospace Telemetry market may be augmented by several
factors. First, there is a need to upgrade telemetry systems installed in the
1970s. Second, scientists' desire to take more detailed and more frequent
measurement of physical processes, coupled with the ability to process data
input more quickly, is leading to requirements for wider bandwidth receivers.
And, third, planned launches of low-earth-orbit ("LEO") satellites to facilitate
new communications services may spur demand for the installation of many new
ground stations, each of which must be equipped with telemetry equipment.

  In addition, the Company has started to address markets beyond its traditional
one for telemetry receivers that serve the R&D, test and evaluation, and
military markets. These new markets and the products for them include:

  - Antennae. Microdyne has designed, built, and sold prototypes of a low-cost,
portable antenna for use by the telemetry community. The antenna enhances the
ability to track and obtain data from missiles during the first minutes after
launch when the vertical change of the missile taxes the tracking ability of
most satellite dishes.

  - New card-level receivers. Microdyne has received requests for proposals from
organizations with requirements for lower-cost receivers for use in a variety of
applications. One near-term opportunity is for receivers to capture and process
data from NASA's "Mission to Planet Earth" satellite series planned for launch
in 1997. Ground stations would be encouraged at schools and universities for
students to study real-time data from these satellites. Lower-cost board-level
Microdyne receivers may be used for such applications.

  While each of the preceding are prospective opportunities, each opens a new, 
multi-million-dollar market to the Company. However, there can be no assurance 
that the Company will realize such opportunities.

Marketing and Sales

space vehicles. The four major user groups include Government testing ranges,
aerospace companies engaged in the development and manufacture of missiles and
satellites, companies that design and manufacture antennae used in tracking and
receiving signals being sent from missiles and satellites and meteorological
systems used to gather weather data.

  Microdyne markets its products directly to these user groups through a sales
and marketing department located at the Company's Ocala, Florida facility.
Because most telemetry products are purchased directly or indirectly with
Government funding, much of Microdyne's marketing effort is channeled into
establishing and maintaining name and product recognition for the Company with
Government agencies and aerospace and defense contractors. Microdyne also
undertakes projects combining the Company's telemetry components and subsystems
with those of other manufacturers for customers worldwide. To service these
customers, Microdyne maintains customer support operations in countries around
the world.

  Government agency and Government prime contractor revenue in fiscal 1996 was
$9.3 million, or 54.7% of total Aerospace Telemetry revenue, compared to $9.6
million, or 55.3% in 1995. The telemetry industry is dependent upon Government
procurement and can be adversely affected by any substantial decreases in direct
Government purchases of the Company's products and services, or in indirect
purchases of products acquired under Government contract. The Company believes
there is growth potential both in domestic and international markets. To address
international opportunities, the Aerospace Telemetry Division has established a
sales office in London, and also uses international manufacturers'
representatives.

Research and Development and Manufacturing

  Expenditures for Aerospace Telemetry research and development totaled $1.5
million, or 8.8% of telemetry revenue in 1996. This compared to $1.4 million, or
8.0% of telemetry revenue in 1995 and $1.2 million, or 9.7% of revenue in 1994.
Microdyne maintains a telemetry products manufacturing facility in Ocala,
Florida.

Competition

  The Company believes the market for telemetry products has entered a new
growth stage after a period of years of stable revenues. Microdyne believes that
of telemetry receivers sold for use in research, development, test and
evaluation, the Company has the largest market share for such products sold in
the world. However, the market for defense electronics is very competitive
and marked by a shift toward fewer, but much larger vendors. Microdyne believes
that the relative maturity of the overall defense electronics market could
attract competition from vendors in related fields of defense electronics that
are seeking to expand total corporate sales by leveraging relationships with
existing customers to include additional product lines in ancillary fields.

MANUFACTURER SUPPORT SERVICES

Overview

  There has been a growing trend in recent years toward the providing of labor
from third-party organizations -- "outsourcing" -- of both technical and
non-technical positions in industry. Outsourcing enables an organization to cope
with changes in growth, seasonality, and constraints on the number of full-time
worked counted as employees. Outsourcing allows an organization to focus its
internal and human resources on activities which will creates the highest rate
of return. Outsourcing may also lower an organization's cost of doing business.
Examples of outsourcing include staffing and operating telephone technical
support centers, warranty repair and after-warranty service centers.

  Since 1989, the Company has provided outsourced services to one large
electronics manufacturer. The activities performed in behalf of this customer
include telephone technical support, component and board repair, warranty
administration, and the operation of a large transit warehouse. Microdyne
provides its customer with trained personnel, including, as of September 29,
1996, a staff of 271 full-time and 160 part-time employees in the customer's
facilities near Los Angeles, California and in Indianapolis, Indiana. The
Company's revenue is based on the number of units repaired or refurbished, or,
alternately, the number of employees assigned to each aspect of the customer's
business, the number of hours worked by those employees and the rate at which
Microdyne is paid for such services.

  The Company maintains a contract with its customer which was renewed for a
period of five years in March 1996.

Marketing

  Microdyne believes it has the skills and depth of management to expand its
Manufacturer Support Services business. While the Company's primary focus is
maintaining and expanding its relationship with its current customer, Microdyne
believes it has the resources and qualifications to serve other customers, and
is currently exploring ways to capitalize on its expertise. There can be no
assurances that the Company will gain new customers through such efforts.

Competition

  The competition for Manufacturer Support Services is both in-house sourcing
and other organizations that specialize in outsourcing. Microdyne's customer
may, upon notice, sever its contract with the Company and elect to perform these
tasks either using its own employees or a third-party support vendor. The
Company believes its relationship with its customer is excellent, and is
evidenced by the fact that the level of work performed for the customer has
expanded significantly during the past two years. Also, for the past three
years, the Company's customer has been ranked #1 in customer service in its
product area by a respected periodical.

  Microdyne seeks to reduce the risk of being displaced by either in-house staff
or another third-party provider by continually recruiting highly skilled staff
to meet the customer's growing requirements, by upgrading the work skills of its
staff through training, and by providing its staff with a career path to reduce
turnover and increase efficiency so as to lower costs to the customer.

PATENTS AND PROPRIETARY RIGHTS

  The Company does not consider that its business is dependent upon patent
protection. Nevertheless, the Company is subject to the risk of adverse claims
and litigation alleging infringement of the proprietary rights of others. From
time to time the Company has received claims of infringement of other parties'
proprietary rights. Although the Company believes that it does not infringe the
valid patents of others, there can be no assurance that third parties will not
assert infringement claims in the future with respect to the Company's current
or future products or that any such claims will not require the Company to enter
into license arrangements or result in protracted and costly litigation,
regardless of the merits of such claims. No assurance can be given that any
necessary licenses will be available or that, if available, such licenses can be
obtained on commercially reasonable terms.

UNITED STATES GOVERNMENT CONTRACTS

  During fiscal 1996 and 1995, $13.5 million, or 14% and $13.1 million, or 8%,
respectively, of Microdyne's total sales were derived from contracts and
subcontracts involving the U.S. Government and its agencies. For fiscal 1996 and
1995, U.S. Government sales as a percentage of each activity's sales were as
follows:

BACKLOG


  Revenue backlog believed to be firm amounted to $5.0 million at September 29,
1996, and $4.8 million at October 1, 1995. Backlog by activity was as follows:

<TABLE>

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

       <S>                                           <C>              <C>

       Aerospace Telemetry.................           3,663,000        2,671,000

</TABLE>


  The Company does not believe backlog is a meaningful indicator of future
business trends. Microdyne's Networking Products operation is not based upon
either long lead times for delivery or contract delivery schedules. Rather, with
the exception of back-ordered products, Networking Products are generally
shipped upon receipt of order. Aerospace Telemetry backlog is dependent upon the
receipt or renewal of Government contracts, the timing over which the Company
has no control.

MICRODYNE CORPORATION                           1996 ANNUAL REPORT ON FORM 10-K
- -------------------------------------------------------------------------------

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

OVERVIEW

  Microdyne's fiscal 1996 results were affected by several events in the
Company's Networking Products Division which overshadowed the excellent
performance of the Company's Aerospace Telemetry and Manufacturer Support
Services divisions. These events included an excess of distribution channel
inventory resulting from an over-estimation of end-user demand for Microdyne's
networking products during 1995, and the adverse effect of changes in Novell,
Inc.'s ("Novell") distribution policies.

- - Beginning in the first quarter of 1996 and continuing throughout the year,
Microdyne sold less product to distributors than those same distributors sold to
end user customers. The $52.7 million of Networking Products hardware shipped in
1996 was substantially less than the Company believes was sold to end user
customers in the same period, based on sales reports supplied to the Company by
distributors.

- - In late 1995 Novell initiated changes in the net effective discount on NetWare
available to Microdyne, which made the sale of NetWare network operating system
software bundled with Microdyne hardware products ("Bundled Products") less
financially attractive to Microdyne in 1996. Fiscal 1995 sales also included
non-recurring demand for NetWare upgrades, the sale of which was curtailed in
December 1995. As a result, Microdyne's sales of Bundled Products declined from
1995 to 1996, from $51.5 million to $15.7 million, with $10.3 million of such
sales occurring in the first quarter.

- - The aerospace telemetry market in which Microdyne competes is in the midst of
a growth cycle. This growth is due to the launching or planned launch of a new
generation of satellites, a desire for more data from vehicles being tested via
telemetry coupled with increased ability to process and evaluate such data, and
an expansion of educational and international opportunities. Microdyne has
developed and is marketing products to serve these audiences.

- - The outsourcing industry, of which the Company's Manufacturer Support Services
division is a part, is experiencing rapid growth. Such growth is a result of
organizations' desire to control costs, constrain headcount, and generally focus
human and financial resources on activities that will produce higher rates of
return. Microdyne believes its core competency in this field can serve as a
template for becoming a provider of high-quality outsourced services to other
customers, though it can provide no assurances of success.

         The above discussion contains forward-looking statements that involve
risks and uncertainties. In addition, certain other factors could cause actual
results to differ materially from management's expectations. The following risk
factors apply to Microdyne's businesses in fiscal 1997 and beyond:

         The networking products industry is one of continuing evolution. While
the LAN adapter card segment is comparatively technologically stable, network
speeds are increasing. In 1996, LAN adapter card manufacturers agreed on a
standard for 100 megabit per second, or "Fast" Ethernet. By mid-year, industry
reports showed that Fast Ethernet sales accounted for more than 15% of total LAN
adapter card demand. Fast Ethernet adapter card prices, which began the year at
a 50% premium to the traditional 10Mbps Ethernet cards, closed to within a 20%
pemium by year-end. While Microdyne believes it has a defensible market share of
the 10Mbps adapter card market, there can be no assurances that the Company's
Fast Ethernet products will be adopted by users, or that Microdyne will be
accorded a similar share of the market.

         For Microdyne to effectively compete in the LAN adapter card industry,
it must match both the price and the features of cards offered by its
competitors. Microdyne believes that, at present, its product prices and
features compare favorably to those of the industry leader. However, Microdyne
believes the coming year will be one of rapid change, with probable decreases in
prices for both 10Mbps and Fast Ethernet products. Should prices decline faster
than Microdyne's ability to reduce manufacturing costs, gross margins will be
adversely affected.

         Microdyne competes against companies far larger than itself, which
offer broader families of networking products, which have substantially greater
marketing resources, and which can call directly on the resellers and end users.
The Company believes the cumulative effect of such competition has the potential
to erode Microdyne's sales over time.

         Microdyne's Networking Products revenue does not always accurately
reflect underlying end-user demand for its products. Determining the appropriate
stocking level for products requires that the Company rely on periodic Point of
Sale ("POS") reports from distributors to assess end-user demand. The
reliability and timeliness of POS information from distributors is not uniform.
The Company endeavors to pro-actively obtain the most reliable reports of sales
out of distribution but, even so, results may be unreliable for reasons beyond
the control of the Company. POS data can only reflect past demand for current
products; not future demand for new or existing products. Ultimately, the
Company must use its best judgement as to what represents adequate distributor
stocks.

         Microdyne believes the use of Novell trade dress (including the Novell
name) on certain of its networking products benefits the Company and accords it
a certain level of continuing demand. In April 1996, Microdyne acquired the
perpetual, exclusive, non-royalty-bearing rights to market more than 30 products
in Novell trade dress, for which Microdyne paid $6.8 million. The marketplace's
perception of Novell's product quality and longevity directly affects the value
of the Novell name on Microdyne's products. This value may be diminished by
erosion of Novell's share of the network operating system market.

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

         The Company's Networking Products Division continues to depend upon
Novell for certain technology and marketing rights. Changes in Novell policies,
channels of distribution, or corporate direction could adversely affect the
Division by impairing the value of its assets or limiting its access to products
and technology.

         Microdyne's Networking Products Division has historically operated with
limited backlog because its products are shipped shortly after orders are
received, and frequently realizes a substantial portion of its net revenues in
the last month of the quarter. As a result, revenue in any quarterly period is
substantially dependent on orders booked and shipped in the last month of that
period. Delays in receipt of end-of-quarter orders in a given quarter may
adversely affect the Company's results of operations for that quarter, as the
Company's expense levels are based primarily on full-quarter revenue estimates
and only a small portion of the Company's operating expenses vary with its
revenue. Accordingly, the Company may be subject to significant and
unanticipated quarter-to-quarter fluctuations.

         Any shortfall in revenue or earnings from the levels expected by
securities analysts could have an immediate and significant effect on the
trading price of the Company's common stock in any given period. Moreover, in
view of historical selling patterns, the Company may not learn of such
shortfalls until late in the fiscal quarter, which could result in an even more
immediate and adverse effect on the trading price of the Company's stock.
Finally, the Company participates in an intensely competitive industry marked by
rapidly changing technology, which may result in significant volatility of the
Company's common stock price.

</TABLE>


FISCAL YEARS ENDED SEPTEMBER 29, 1996 AND OCTOBER 1, 1995

Revenue. Revenue for fiscal 1996 decreased to $99.2 million from $170.1 million
in fiscal 1995, a decrease of 41.8%. This decrease was a result of lower sales
at the Company's Networking Products division.

         As a result of lower networking hardware sales and higher revenue from
professional service sources, Microdyne now reports revenue derived from
products and revenue derived from services separately. Service revenue accounted
for 15.0% of fiscal 1996 revenue compared to 7.4% in fiscal 1995.

         Networking Products revenue decreased to $68.4 million in 1995 from
$141.3 million in 1994, a decrease of 51.6%. The decrease reflects lower sales
of Bundled Products, which declined from $51.5 million to $15.7 million for the
reasons outlined in the "Overview" above. Sales of networking hardware products
declined from $89.8 million to $52.7 million. The preponderance of this decrease
was due to the Company's decision to re-balance channel inventory held by
distributors.

         The Company shipped less product in each of its principal sales
categories: PC Connectivity products (including Ethernet and Token Ring adapter
cards), and Minicomputer and Mainframe Connectivity products. Within the PC
Connectivity products, Microdyne saw an increase in demand for Fast Ethernet
adapter cards, which the Company believes will gradually replace 10Mbps
technology. Fast Ethernet products accounted for 23.8% of shipments in the
fourth quarter of fiscal 1996.

         The Company also saw increases in two distribution segments in 1996:
sales to other adapter card providers of Microdyne's 100Mbps ISA-bus adapter,
and sales to U.S. Government ("Government") agencies. Microdyne sells its Fast
Ethernet ISA-bus product to three companies on an OEM basis, and its products
are now included on 11 Government contracts, up from six in 1995.

         Microdyne believes there was an absolute decline in demand for
Minicomputer and Mainframe

MICRODYNE CORPORATION                           1996 ANNUAL REPORT ON FORM 10-K
- -------------------------------------------------------------------------------

Connectivity products in 1996, reflecting the industry's evolution away from
such computing solutions.

         Aerospace Telemetry revenue was relatively stable at $17.0 million in
1996 versus $17.4 million in 1995, largely as a result of continued demand for
the Company's telemetry products. Manufacturer Support Services revenue
increased to $14.4 million from $12.1 million in fiscal 1995, reflecting
continued growth in support activities for this division's customer.

         Gross Profit. Gross profit decreased to $27.3 million in 1996 from
$52.8 million in 1995, and as a percentage of revenue decreased to 27.6% from
31.0%. The decrease in dollars reflects lower sales versus fiscal 1995. The
percentage decrease in gross margin is attributable to lower gross margins in
the Company's Networking Products activity, which was affected by lower
absorption of manufacturing overhead over a small sales base and acceleration of
certain expenses offset partially by lower sales of low-gross-margin Bundled
Products and decreased royalty payments in the fourth quarter. Gross profit was
relative unchanged at the Aerospace Telemetry and Manufacturer Support Services
divisions.

         Selling, General and Administrative. Selling, general and
administrative expense was relatively stable at $23.4 million in 1996 versus
$23.6 million in 1995, but increased as a percentage of revenue to 23.6% from
13.9%. The increase as a percentage of sales was due principally to the
Company's inability to shed committed costs in the first half of the year at the
Networking Products division. By the fourth quarter, annualized SG&A expense had
fallen to $21.8 million. Amortization of product line acquisition costs rose to
$2.6 million in 1996 from $1.2 million in 1995, due principally to the purchase
of National Semiconductor's Ethernet adapter card product line in September 1995
and the acquisition in April 1996 of perpetual rights to market certain
Novell-developed technology and the use of Novell trade dress on certain
products.

         Research and Development. Research and development expense decreased to
$4.2 million in 1996 from $4.7 million in 1995 but increased as a percentage of
revenue to 4.2% from 2.8%. The percentage increase is due principally to
relatively stable R&D costs at the Company's Networking Products division spread
over a lower sales base.

         Other Income (Expense).  Other expense in both 1996 and 1995 includes
interest expense associated with outstanding borrowings against the Company's
line of credit. The higher interest expense in 1996 was due to larger
outstanding borrowings caused by acquisitions and reduction of trade payables.

         Provision for Income Taxes. The Company accrued a benefit from income
taxes of $2.0 million in 1996 versus a provision for income taxes of $7.8
million in 1995. The benefit was due to the Company's net loss for the year.

FISCAL YEARS ENDED OCTOBER 1, 1995 AND SEPTEMBER 30, 1994
Revenue. Revenue for fiscal 1995 increased to $170.1 million from $101.3 million
in fiscal 1994, an increase of 67.9%. This increase was a result of internal
growth in each of the Company's three operations and Networking Products
acquisitions.

         Networking Products revenue increased to $141.3 million in 1995 from
$80.5 million in 1994, an increase of 75.5%. The growth reflects acquisitions by
Microdyne, the continued growth of the LAN products industry and the Company's
increased market share. PC Connectivity products, which include the Company's
Ethernet and Token Ring adapter cards, increased to $76.5 million in 1995 from
$31.6 million in 1994, an increase of 142.0%. The increase reflects recent
acquisitions, particularly the Eagle acquisition in January 1995. Total Ethernet
revenue increased to $60.6 million in 1995 from $27.3 million in 1994. Token
Ring revenue increased to $15.9 million in 1995 from $4.4 million in 1994.
Revenue from sales of Microdyne hardware bundled with Novell software ("Bundled
Products") increased to $51.5 million in 1995 from $28.8 million in 1994.
Reflecting industry trends, Minicomputer Connectivity and Mainframe Connectivity
product revenue declined $4.1 million in 1995 from 1994.

         Aerospace Telemetry revenue increased to $17.4 million in 1995 from
$12.3 million in 1994, largely as a result of demand for the Company's new
telemetry products and Government contracts received late in 1994. Manufacturer
Support Services revenue increased to $12.1 million from $8.0 million in fiscal
1994, reflecting continued growth in support activities for the Company's
customer. The Industrial Telemetry operations, which contributed $738,000 in
1994, was sold in December 1993.

         Gross Profit. Gross profit increased to $52.8 million in 1995 from
$28.0 million in 1994, and as a percentage of revenue increased to 31.0% from
27.7%. The increase in gross margin is attributable to higher gross margins in
the Company's Networking Products activity. Gross profit also increased in the
Aerospace Telemetry and Manufacturer Support Services operations.

         Selling, General and Administrative. Selling, general and
administrative expense grew to $24.4 million in 1995 from $16.7 million in 1994,
but decreased as a percentage of revenue to 14.3% from 16.4%. Amortization of
product line acquisition cost from acquisitions made to date will result in an
annual expense of approximately $1.3 million for the next six fiscal years and
approximately $900,000 in the following year.

         Research and Development. Research and development expense increased to
$5.2 million in 1995 from $3.6 million in 1994 but decreased as a percentage of
revenue to 3.1% from 3.5%. The dollar increase

is attributable to the addition of former DCA Token Ring engineers in the fourth
quarter of 1994 as well as the development of new products introduced in 1995.

         Other Income (Expense).  Other expense in both 1995 and 1994
includes interest expense associated with outstanding borrowings against the
Company's line of credit. The higher interest expense in 1995 was due to larger
outstanding borrowings which financed the Eagle acquisition. Also included in
1995 are one-time charges totaling $875,000, in connection with the settlement
of a stockholder class action lawsuit filed against the Company in 1992.

         Provision for Income Taxes. Provision for income taxes was $7.8 million
(38.3% of pre-tax earnings) and $2.7 million (37.0% of pre-tax earnings) in 1995
and 1994, respectively. The increase in the effective tax rate resulted in part
from reduced tax credits, the impact of which was partially offset by lower
percentage state income taxes and benefits from the Company's foreign sales
corporation.

LIQUIDITY AND CAPITAL RESOURCES

         During the past three years, the Company has financed its operations
principally through internally generated funds. However, the Company has secured
external financing in connection with acquisitions and the repurchase of its
common stock.

         External financing has been primarily provided through bank borrowings.
As of September 29, 1996, the Company has $17.5 million of bank debt, consisting
of a $3.1 million term note which is repaid in monthly payments and scheduled to
be fully satisfied in May 1997; and $14.4 million in outstanding borrowings
under a revolving line of credit facility (see Note G to the Notes to the
Consolidated Financial Statements). On September 29, 1996, the Company had $1.8
million of cash and $3.1 million available for borrowing under its revolving
credit facility. The Company is required to repay its bank borrowings on a
schedule which will result in the extinguishment of all current bank debt prior
to December 31, 1997. The Company believes that based on its current forecast of
cash generation it will meet that schedule.

         In April 1996, the Company utilized cash and notes to purchase from
Novell the exclusive, royalty-free perpetual right to market certain hardware
and related technology which were previously sold by the Company under license
from Novell, and to convert certain accounts payable. As of September 29, 1996,
notes payable due Novell totaled $7.9 million, of which $2.5 million has been
classified as as short-term obligation and $5.4 million as long-term obligations
on the September 29, 1996 Balance Sheet.

         During fiscal 1996, net cash used by operating activities was $0.9
million, primarily due to a net loss. Decreases in accounts receivable and
inventories were mostly offset by decreases in accounts payable and accrued
expenses. The decreases in accounts receivable and accounts payable reflect the
Company's reduced level of business. Cash used from investing activities was
$1.4 million, most of which reflected the Novell acquisition. Capital
expenditures were minimal and the Company has no material commitments for future
capital expenditures. Cash used in financing activities was $0.4 million
representing payments on notes largely offset by additional borrowings.

         The Company believes its available cash, funds generated from
operations, and funds available under its credit facilities should be sufficient
to finance its continuing operations in fiscal 1997. The Company may from time
to time consider the acquisition of businesses, products, or technologies that
may require additional funds.

INFLATION

         For the past three years, inflation has not had a significant impact on
the Company's operations.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


Board of Directors
Microdyne Corporation


We have audited the accompanying consolidated balance sheets of Microdyne
Corporation (the Corporation) as of September 29, 1996 and October 1, 1995, and
the related consolidated statements of operations, stockholders' equity and cash
flows for each of the three years in the period ended September 29, 1996. These
financial statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above, present
fairly, in all material respects, the financial position of Microdyne
Corporation as of September, 29, 1996 and October 1, 1995, and results of its
operations and its cash flows for each of the three years in the period ended
September 29, 1996 in conformity with generally accepted accounting principles.

                              MICRODYNE CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           September 30, 1994, October 1, 1995, and September 29, 1996

NOTE A - NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

1.    NATURE OF OPERATIONS

      Microdyne Corporation is comprised of three divisions. Its Networking
Products division develops, manufactures, and markets a broad line of network
connectivity products. Its Aerospace Telemetry division manufactures and sells
aerospace telemetry receivers and ancillary devices, and provides systems
integration services. Its Manufacturer Support Services division provides
outsourced services including telephone technical support and warranty and
product repair.

2.    PRINCIPLES OF CONSOLIDATION

      The consolidated financial statements include Microdyne Corporation,
Microdyne Ltd., and Microdyne U.K. All significant intercompany amounts have
been eliminated in consolidation.

3.    REVENUE RECOGNITION

      Revenue from the sale of computer hardware, peripheral equipment and
computer networking products, including software, is recognized when the
products are shipped. Service revenue is recognized as service is provided.
Revenue from the manufacture of aerospace telemetry products and systems is
recognized using the percentage-of-completion method where progress is measured
based on costs incurred to date as compared to total expected costs. Estimated
losses on aerospace telemetry contracts, if any, are recognized when they are
identified.

      The Company provides terms of net 30 days for most products its sells. On
certain products, these terms may be extended at the discretion of management.

      The Company's agreements with distributors allow defective products to be
returned for credit. Distributor terms also permit stock rotation of products, a
standard practice in the electronics industry. The Company from time to time
sells products on a non-cancellation, no-return basis. In such cases, pricing
will reflect the non-cancellable nature of the order. Distributor agreements
also provide distributors with protection against price decreases applicable to
products in distributors' inventories at the time of the decrease. Provision has
been made in the accompanying financial statements for the estimated liability
associated with defective product returns, stock rotations, and price decreases.

      The Company's business activity is geographically diverse, with sales
within the United States as well as in foreign countries. The Company's exposure
to credit risk associated with nonperformance of these customers in fulfilling
its contractual commitment is limited to the contractual amount of the
receivable.

      Generally, in its Networking Products business, the Company must
manufacture products in advance of orders from distributors and must, therefore,
estimate demand as accurately as possible. Distributors provide certain
information regarding their levels of sales to value-added resellers and other
customers, called Point of Sale ("POS") data, but such POS information cannot be
assured to be either timely or accurate. In addition, distributors maintain
target stocking levels of products, and such targeted levels may change without
notice, which could decrease the Company's revenue in a given period. Moreover,
distributors characteristically sell products at a small mark-up to the price
from which they are obtained from manufacturers, and terms of sale may influence
a distributor's decision to carry certain products. Based on inadequate POS and
end user information, unanticipated distributor targeted stocking levels,
unanticipated price competition, or otherwise, the Company may be unable to
estimate production requirements of its distributors and future sales levels
generally, the Company's revenue may fluctuate due to production in excess of
demand. Moreover, the inability of the Company to timely market excess
inventory, if any, on economically viable terms could have a material adverse
effect on the Company. Conversely, if the Company's production is insufficient
to satisfy demand, the Company could be adversely affected.

4.    INVENTORIES

Inventories are stated at the lower of cost or market. Inventories are
standard-cost based, with such standards reviewed periodically against purchase
prices and adjusted as appropriate.

         POLICIES - CONTINUED

5.    PROPERTY AND EQUIPMENT

Property and equipment are stated at cost and are depreciated or amortized using
the straight-line method over the following estimated useful lives:


<TABLE>
                  <S>                                  <C>     
                  Machinery and equipment                                             3-10 years
                  Buildings                                                             20 years
                  Furniture and fixtures                                             3 - 5 years
                  Automobiles                                                          3-5 years
                  Leasehold improvements               Shorter of term of lease or life of asset
</TABLE>

6.    CAPITALIZED SOFTWARE COSTS

      Included in other assets as of September 29, 1996 is $433,000 in net
capitalized software costs. The Company's policy is to expense the costs
incurred prior to establishment of technological feasibility. The establishment
of technological feasibility and the ongoing assessment of recoverability of
capitalized software development costs require considerable judgment by
management with respect to certain external factors, including anticipated
future gross revenue, estimated economic life and changes in technologies.
Development costs beyond the point of technological feasibility are capitalized.
Amortization, which begins when the product is available for general release,
occurs over the estimated economic life which is typically between one and two
years. Amortization expense associated with capitalized software costs for the
years ended September, 30, 1994, October 1, 1995, and September 29, 1996 was
$473,000, $494,000 and $775,000, respectively.

7.    EARNINGS PER SHARE

      Earnings per common and common equivalent share is computed by dividing
the earnings or loss by the weighted average number of common and common
equivalent shares outstanding during the respective years.

      The weighted average number of shares outstanding with the number of
shares used in the computation of earnings per share is as follows (in
thousands):

                                                                    -------        -------          ------
                                                                     13,088         13,096          12,811
</TABLE>

8.     FISCAL YEAR

         During fiscal year 1995, the Company changed its fiscal year from
September 30 each year to a 52 or 53 week year ending on the Sunday nearest the
last day of September in each year. Therefore, fiscal years 1995 and 1996 ended
on October 1, 1995 and September 29, 1996, respectively, whereas fiscal year
1994 was under the fiscal calendar which ended on September 30. 1994. All
references to years relate to fiscal years rather than calendar years.

9. 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.

10.     CASH AND CASH EQUIVALENTS

         For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.

11.     RECLASSIFICATIONS

         Certain amounts in the 1994 and 1995 financial statements have been
reclassified to conform to the 1996 presentation.

NOTE B - ACQUISITIONS AND DISPOSITIONS

         In April 1996, the Company purchased from Novell the exclusive
royalty-free perpetual rights to market certain hardware products and related
technology for $6.8 million in cash and notes. See Notes G and I4. The
amortization period for the purchased intangibles, based on management's
estimate of the useful life of the acquired rights, is seven years. The Company
had previously licensed the rights to sell and market such products under
various license agreements.

         In September 1995, the Company acquired the Ethernet product line from
National Semiconductor ("National"). This acquisition included certain
intangibles of $1.8 million and National's 10Mb and 10/100Mb Ethernet adapter
card inventory of approximately $3.5 million. The amortization period for the
intangibles, based on management's estimate of the useful life of the acquired
technology, is seven years.

         In January 1995, the Company acquired the Eagle Technology ("Eagle")
business from Artisoft, Inc. Eagle provided the Company with a family of
Ethernet adapter cards, file server cards, hubs, and print server cards. The
purchase price was $16.5 million, representing $8.3 million in inventory, $7.5
million in goodwill and other intangibles, and $700,000 in fixed assets. The
amortization period for the intangibles, based on management's estimate of the
useful life of the acquired technology, is seven years.

         The Company also acquired certain product lines, inventory, fixed
assets and intellectual property from Gateway Communications, Inc. for two
million dollars in a purchase transaction initiated in June 1994 and completed
in September 1994.

         In July 1994, Digital Communications Associates (DCA) sold to the
Company certain fixed assets, property, rights, and inventory related to DCA's
Token Ring product line. The purchase price was approximately seven million
dollars, representing the net book value of the assets sold and guaranteed
minimum royalties of three million dollars. This minimum royalty commitment
covers five years and the long-term portion is presented as both a product line
acquisition cost and a long-term obligation in the consolidated balance sheets.
Such deferred minimum royalties will be amortized over five years as payments
are made.

         In December 1993, the Company sold the net assets and operations of
Wireless Data Corporation, a subsidiary which manufactured industrial telemetry
products, for one million dollars in cash and a $300,000 note which was
subsequently paid.

         On an ongoing basis, management reviews the valuation and amortization
of product line acquisition cost to determine possible impairment. The
recoverability of product line acquisition cost is assessed by determining
whether the amortization of such cost over its remaining life can be recovered
through projected undiscounted future cash flows.

         Under Statement of Financial Accounting Standards No. 107, "Disclosures
about Fair Value of Financial Instruments," effective for fiscal years that end
after December 15, 1995, the Company is required to provide fair value
disclosures of its financial instruments beginning in fiscal year 1996.

         Outstanding Borrowing Base Loans approximate their fair values as the
interest rate fluctuates. The notes payable are not instruments with readily
available market values. The stated note interest rates are 8% and, based on the
currently prevailing prime rate of approximately 8%, the net book values of the
notes payable as of September 29, 1996 approximate their fair values as
calculated.

NOTE H - INCOME TAXES

         The Company provides for income taxes using the liability method.
Deferred income taxes are classified as current or noncurrent, based on the
classification of the related assets and liabilities giving rise to the
temporary difference.

2.       LITIGATION

         In fiscal 1995, the Company settled (and reflected as an $875,000
charge to Other Expense) a shareholder class action lawsuit.

3.       EMPLOYMENT AND NONCOMPETITION AGREEMENTS

         The Company is committed under long-term employment and noncompetition
agreements with an officer. Approximate future minimum annual payments required
under the agreements are $475,000 and expire in fiscal 1999.

4.       ROYALTIES

         Prior to April 1996, the Company paid royalties to Novell in return
for the non-exclusive, worldwide right to manufacture and distribute various
hardware networking products under multiple licensing agreements.

         In April 1996, the Company purchased from Novell the exclusive
royalty-free perpetual right to market certain hardware products and related
technology which had been subject to many of the licensing agreements above.
The $6.8 million purchase price gave the Company the right to sell more than 30
products and product families in Novell trade dress. Previously, the Company's
right to sell under the Novell brand name could be withdrawn at any time by
Novell, and Novell could grant similar rights to other companies. See Note G.

         The Company is required to pay royalties to Attachmate (formerly DCA)
pursuant to that product line acquisition in July 1994 (see Note B). The
residual guaranteed minimum royalty due Attachmate at September 29, 1996 in the
amount of $1,132,000 has been capitalized as a product line acquisition cost
with a corresponding liability. The recovery of the capitalized cost is
dependent upon related sales levels sufficient to generate such outstanding
guaranteed minimum royalty.

         Total royalty expense was $4,560,000, $6,374,000, and $2,445,000 for
the years ended September 30, 1994, October 1, 1995, and September 29, 1996,
respectively. In addition, included in cost of goods sold are product purchases
from Novell of $25,758,000, $43,455,000, and $12,575,000 for the years ended
September 30, 1994, October 1, 1995, and September 29, 1996.

NOTE N - ACCOUNTING STANDARDS

1.   ACCOUNTING FOR STOCK-BASED COMPENSATION

         The Financial Accounting Standards Board recently issued Statement of
Financial Accounting Standards No. 123 (SFAS 123), "Accounting for Stock-Based
Compensation," effective for fiscal years that begin after December 15, 1995.
The new standard encourages all entities to adopt a fair value based method of
accounting for all employee stock option plans. Under this method, compensation
cost is measured at the grant date based on the value of the stock option award
and is recognized over the service period, which is usually the vesting period.
Optionally, a company may continue to use the intrinsic value method, as
described by Opinion 25, that measures compensation costs only to the extent
that the option price is lower than the quoted market price of the stock at the
date of the award. In fiscal year 1997, the Company expects to continue the
application of Opinion 25, but will comply with the pro forma disclosures of
net income, and earnings per share, as if the fair value based method of
accounting defined in SFAS 123 had been applied.

2.   ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED
     ASSETS TO BE DISPOSED OF

         The Financial Accounting Standards Board recently issued Statement of
Financial Accounting Standards No. 121 (SFAS 121), "Accounting for the
Impairment of Long-Lived Assets to Be Disposed Of," effective for fiscal years
that begin after December 15, 1995. The new standard requires a company to
review for impairment long-lived assets and certain identifiable intangibles to
be held and used whenever events or changes in circumstances indicate the the
carrying amount of an asset may not be recoverable. If the events or changes in
circumstances are present, an impairment loss should be recognized. The
Company's long-lived assets consist of land and buildings in Ocala, Florida;
purchased intangibles; and capitalized software costs. In management's opinion,
no events or changes in circumstances exist relating to the Company's
long-lived assets that would have resulted in any impairment losses being
recognized had the Company implemented SFAS 121 in fiscal year 1996 and earlier
years.

                 THIS SECOND AMENDMENT TO CREDIT AGREEMENT (the "Amendment"),
dated and effective as of June 30, 1996, is made by and between MICRODYNE

Banks.

                                    RECITALS

Agreement, dated as of January 27, 1995, and amended by the First Amendment to

Agreement shall have the same defined meanings when such terms are used in this
Amendment.

                 The Borrower, the Agent and the Banks have agreed to amend
certain provisions of the Agreement.  Accordingly, for valuable consideration,
the receipt and sufficiency of which are acknowledged, the Borrower, the Banks
and the Agent agree as follows:

                 1.      The following definition is added to Section 1.1 of
the Agreement:

                                    "Borrowing Base Loans" means, at the time
                 in question, the sum of (a) the aggregate of the principal
                 balances of the outstanding Advances, (b) the aggregate of the
                 principal balances of the outstanding Term Loans, and (c) the
                 aggregate of the face amounts of the outstanding Letters of
                 Credit.

                 2.       The following definitions contained in Section 1.1
of the Agreement are deleted in their entirety and replaced with the following
provisions:

                                    "Advance Commitment" means $15,619,500 in
                 the case of Crestar and $6,880,500 in the case of NBD;

                 reduced automatically by its Commitment Percentage of any
                 Maximum Amount reduction resulting from a prepayment of the
                 Advances pursuant to Section 2.10(e).

                                    "Borrowing Base" means, at the time in

                 lease or service that have been formally awarded to the
                 Borrower and for which all required contract documents have
                 been executed by the Customer and the Borrower and, in the
                 case of Accounts Receivable owed by the Government, for which
                 funds have been appropriated and allocated; (b) with respect
                 to which the applicable goods have been delivered to and
                 accepted by the Customer on an absolute sale basis and not on
                 a bill and hold sale basis, a consignment sale basis, a
                 guaranteed sale basis, a sale or return basis or on the basis

                 other credits applicable thereto; (f) that are subject to no
                 Liens other than those permitted by this Agreement; (g) that
                 continue to be in full conformity with the representations and
                 warranties made by the Borrower to the Banks in this Agreement
                 and the Security Agreement; (h) with respect to which the
                 Banks are and continue to be satisfied with the credit
                 standing of the Customer; (i) on which the Customer is not a
                 creditor of the Borrower; and (j) on which, unless an
                 Acceptable Foreign Customer or otherwise approved by the Banks
                 in writing, in their sole discretion, the Customer is not a
                 Foreign Customer; provided, however, and without limiting any
                 other provisions of this Agreement with respect to the
                 exclusion of Receivables from the category of Eligible
                 Receivables and the Borrowing Base, that (1) if either Bank
                 reasonably determines that the collectibility of any Account
                 Receivable makes it unacceptable for inclusion as an Eligible
                 Receivable and gives written notice to the Borrower indicating
                 the reasons for such determination, then such Account
                 Receivable shall thereafter be excluded from the category of
                 Eligible Receivables, (2) if more than 50% of the aggregate
                 face amount of Accounts Receivable owed by a Customer other
                 than the Government are aged more than 90 days from the dates
                 of the initial invoices, then all Accounts Receivable owed by
                 such Customer shall be included in a separate line item on the
                 Agings and, at the option of either Bank, shall be excluded
                 from the category of Eligible Receivables, and (3) in no case
                 shall Eligible Receivables include any Account Receivable
                 representing or arising out of retainages, holdbacks, revenues
                 recognized or costs incurred in excess of approved or allowed

                 Inventory, valued at the lower of cost or market, but in no
                 event shall the Inventory Component included in the Borrowing
                 Base be more than $5,000,000.

                          "Maximum Amount" means, with respect to the Advances,
                 $22,500,000; provided, however, that the applicable Maximum
                 Amount on any date





                                       2
<PAGE>   3
                 shall be further reduced by the amount of the prepayment of
                 the Advances required by Section 2.10(e) of this Agreement.

                                    "Spread" shall mean 2.50%.

                 pursuant to Section 9.1, or any later date if the Termination
                 Date is extended in the sole discretion of the Banks in
                 accordance with Section 2.4.

                 3.       The last sentence of Section 2.1(a) is deleted in
its entirety and replaced with the following:

                 "Within the limits of each Bank's Advance Commitment and up to
                 the Maximum Amount, the Borrower may borrow, prepay pursuant
                 to Section 2.10 and reborrow hereunder from the date of this
                 Agreement until the Termination Date; provided, however, that
                 no Advance will be disbursed by any Bank if, after such
                 disbursement, the Borrower would be required to make a
                 prepayment of the Obligations in accordance with the
                 provisions of Section 2.10(d)."

                 4.       Section 2.1(b) is deleted in its entirety and
replaced with the following provisions:

                                    "(b)   In addition to the prepayments
                 required by Sections 2.10(d) and (e), the Borrower shall 
                 immediately prepay the Advances to the extent that the sum of 
                 the aggregate unpaid principal balance of the Advances plus the
                 aggregate face amounts of the Letters of Credit at any time
                 exceeds the Maximum Amount then applicable.  If, after any
                 mandatory prepayment of the Advances, all or a portion of the
                 aggregate face amount of outstanding Letters of Credit still
                 exceeds the applicable Maximum Amount, the Borrower, within
                 five days of the Agent's demand therefor, shall pay to the
                 Agent an amount of cash equal to such excess amount, and such
                 amounts of cash shall be held by the Agent in a cash
                 collateral account for the benefit of the Banks, over which
                 the Agent shall have the exclusive power of withdrawal, as
                 security for the Obligations arising out of the Letters of
                 Credit and the corresponding LC Agreements."

                 5.       The following provisions are added to the end of
Section 2.10:

                          "(d) The Borrower shall immediately prepay the
                 Obligations to the extent that the Borrowing Base is less than
                 70% of the outstanding Borrowing Base Loans at any time.

                          (e)       The Borrower shall apply the net sales
                 proceeds of any debt or equity securities issued by the
                 Borrower or any assets sold by the Borrower (other than
                 Inventory sold in the ordinary course of business) to the
                 prepayment of the Obligations.

                          (f)       Any prepayments required by Sections
                 2.10(d) or (e) shall be applied first to the Term Loans, then
                 to the Advances and then to the cash collateral account for
                 the Letters of Credit described in Section 2.1(b)."

                 6.       The first sentence of Section 2.11 is deleted and
replaced with the following:

                          "(a)      In consideration of Advances to be made by 
                 the Banks, the Borrower agrees to pay to the Agent for the 
                 account of each Bank a commitment fee equal to 1/8 of 1% per 
                 annum of the Maximum Amount, to be paid on July 1, 1996."

                 7.       Subsection (1) of Section 7.1(b) is deleted in its
entirety and replaced with the following:

                                    "(1) As soon as available and, in any
                 event, within 20 days after the end of each calendar month,

                 stockholders' equity of the Borrower and its Subsidiaries for
                 the period commencing at the end of the previous fiscal year
                 and ending with the last day of the preceding month, all in
                 reasonable detail and stating in comparative form the
                 respective consolidated figures for the corresponding date and
                 period in the previous fiscal year and all prepared in
                 accordance with GAAP.  Such statements shall be accompanied by

                 goods Inventory by division and revenues and gross profits by
                 division.  Such financial statements and reports shall be

                               THIRD AMENDMENT TO
                                CREDIT AGREEMENT

                 THIS THIRD AMENDMENT TO CREDIT AGREEMENT (the "Amendment"),
dated and effective as of August 19, 1996, is made by and between MICRODYNE
CORPORATION, a Maryland corporation (the "Borrower"), CRESTAR BANK and NBD BANK
(the "Banks"), and CRESTAR BANK ("Crestar") as agent (the "Agent") for the
Banks.

                                    RECITALS

                 The Borrower, the Banks and the Agent are parties to a Credit
Agreement, dated as of January 27, 1995, and amended by the First Amendment to
Credit Agreement, dated as of October 26, 1995, and the Second Amendment Credit
Agreement, dated as of June 30, 1996 (as further amended, modified or
supplemented from time to time, the "Agreement").  Terms defined in the
Agreement shall have the same defined meanings when such terms are used in this
Amendment.

                 The Borrower, the Agent and the Banks have agreed to amend
certain provisions of the Agreement.  Accordingly, for valuable consideration,
the receipt and sufficiency of which are acknowledged, the Borrower, the Banks
and the Agent agree as follows:

                 1.       The following definition is added to Section 1.1 of
the Agreement:

                                  "Mortgage" means a Mortgage, in form and 
                 substance acceptable to the Banks, creating a lien against 
                 the land, buildings and fixtures located at 491 Oak Road, 
                 Ocala, Florida, as the same may be amended, modified or
                 supplemented from time to time.  The Mortgage shall be a Loan
                 Document, as defined in this Agreement.

                 2.       The following definitions contained in Section 1.1
of the Agreement are deleted in their entirety and replaced with the following
provisions:

                                  "Advance Commitment" means $13,884,000 in 
                 the case of Crestar and $6,116,000 in the case of NBD; 
                 provided, however that each Bank's Advance Commitment shall be 
                 reduced automatically by its Commitment Percentage of any 
                 Maximum Amount reduction resulting from a prepayment of the 
                 Advances pursuant to Section 2.10(e).

                                  "Maximum Amount" means, with respect to the 
                 Advances, $20,000,000; provided, however, that the applicable 
                 Maximum Amount on any date
<PAGE>   2
                 shall be further reduced by the amount of the prepayment of
                 the Advances required by Section 2.10(e) of this Agreement.

                                  "Termination Date" means September 19, 1996, 
                 any earlier date of termination in whole of the Commitments
                 pursuant to Section 9.1, or any later date if the Termination
                 Date is extended in the sole discretion of the Banks in
                 accordance with Section 2.4.

                 3.       Section 2.l(a) is deleted in its entirety and
replaced with the following:

                 "Subject to the terms and conditions of this Agreement, each
                 Bank severally may make Advances to the Borrower from time to
                 time until the Termination Date in an aggregate amount not to
                 exceed at any time outstanding such Bank's Advance Commitment.
                 The aggregate outstanding amount of Advances shall not exceed
                 the Maximum Amount at any time, unless the Banks, in their
                 sole discretion elect to make Advances in excess of such
                 limit, which Advances, if made, shall be subject to the terms
                 of this Agreement.  All Advances will be made from time to
                 time in the sole discretion of the Banks, and this Agreement,
                 the making of any Advance or any other action by any Bank
                 shall not obligate the Banks to make further Advances to the
                 Borrower.  The Borrower acknowledges and agrees that the Banks
                 may decline to make an Advance for any reason, even if no
                 Default or Event of Default has occurred and if the Borrower
                 is in compliance with all of the terms and conditions of this
                 Agreement.  By close of business on Tuesday of each week prior
                 to the Termination Date, Borrower shall prepare and deliver to
                 the Agent a weekly cash projection showing Borrower's
                 projected receipts, disbursements, and Advance requests for
                 the next seven calendar days.  Subject to the foregoing,
                 within the limits of each Bank's Advance Commitment and up to
                 the Maximum Amount, the Borrower may borrow, prepay pursuant
                 to Section 2.10 and reborrow hereunder from the date of this
                 Agreement until the Termination Date."

                 4.       The following provisions are added to the end of
Article 4:

                          "SECTION 4.4 Mortgage.  As additional security for
                 the Obligations, the Borrower shall use its best efforts to
                 execute, deliver and record the Mortgage in the appropriate
                 land records not later than September 6, 1996, and deliver to
                 the Agent, not later than September 13, 1996, a mortgagee
                 title insurance commitment, issued by a title insurance
                 company acceptable to the Banks, to insure the Lien of the
                 Mortgage as a second Lien, subordinate only to the Lien
                 securing the Industrial Development Revenue Bonds described on
                 Schedule 4 to this Agreement, and containing no exceptions to
                 title that are not acceptable to the Banks in their sole
                 discretion.

                 SECTION 4.5 Cash Collateral Account.  The Borrower agrees that
                 it shall direct all payments on Receivables to a lockbox
                 established with the Agent.  The Borrower also agrees to remit
                 all payments on Receivables received by the Borrower, as well
                 as any



                                      2
<PAGE>   3
                 other revenues of any kind (including, without limitation, any
                 income tax refunds) received by the Borrower, to the Agent.
                 All of the foregoing payments and revenues shall be remitted
                 or delivered to the lockbox or the Agent, as applicable, in
                 their original form on the date of receipt. All such payments
                 and revenues shall be credited to a cash collateral account
                 over which the Agent shall have the exclusive power of
                 withdrawal.  The Agent shall hold all funds in the cash
                 collateral account as security for the Obligations and is
                 authorized to apply funds in the cash collateral to pay the
                 Obligations from time to time.  The Borrower represents that
                 it does not have an account with any financial institution
                 other than the Agent, save and except those accounts set forth
                 on Schedule A ("Other Accounts"). The Borrower agrees that it
                 shall not establish any other account hereafter without prior
                 written approval of the Agent.  The Borrower further agrees
                 that proceeds of Receivables totalling in excess of $25,000
                 deposited in any Other Account shall be transferred to the
                 cash collateral account established hereunder within 24 hours
                 of such deposit and all other proceeds of Receivables
                 deposited in any Other Account shall be transferred to said
                 cash collateral account within 48 hours of such deposit.  The
                 Borrower shall respond to requests by the Agent for
                 information or documents relating to the Other Accounts and
                 the balances therein within 24 hours of its receipt of each
                 such request."

                 5.       Pursuant to the provisions of Subsection (9) of
Section 7.1(b), the Borrower agrees to provide to the Agent, (a) on each
Business Day on which Receivables are created or collected, or on which
Inventory is purchased, shipped or returned, or on which a credit is issued or
created with respect to a Receivable, a sales journal on a form provided by the
Agent reflecting such activity and the resulting balance of Receivables and
Inventory, and (b) on each Business Day, a summary, by budget category, of all
disbursements in excess of $5,000 made by the Borrower on the immediately
preceding Business Day.

                 6.       Except for the amendments to the Agreement expressly
set forth above, the Agreement and the other Loan Documents shall remain in
full force and effect.  The Borrower acknowledges and agrees that this
Amendment only amends the terms of the Agreement and is not a novation, and the
Borrower ratifies and confirms the remaining terms and provisions of the
Agreement and the other Loan Documents in all respects.  Nothing in this
Amendment shall require the Banks to grant any further amendments to the terms
of the Loan Documents.  Without limiting the generality of the foregoing, the
Borrower acknowledges and agrees that it is obligated to develop a business
plan acceptable to the Banks as required by the August 19, 1996 letter from the
Agent to the Borrower, and that no Advances will be made after September 16,
1996, unless such business plan is received by the Banks.

                 7.       The Borrower acknowledges and agrees that (a) there
are no defenses, counterclaims or setoffs against any of its obligations under
the Loan Documents, and (b) the prior grant of a security interest in the
Collateral created by the Security Agreement and the Patent and Trademark
Assignment continues to secure the Obligations, is in full force and effect,
and is ratified and confirmed by the Borrower in all respects.

                 8.       The Borrower represents and warrants that this
Amendment has been duly authorized, executed and delivered by it in accordance
with resolutions adopted by its board of directors. All other representations
and warranties made by the Borrower in the Loan Documents are incorporated by
reference in this Amendment and are deemed to have been repeated as of the date
of this Amendment with the same force and effect as if set forth in this
Amendment, except that any representation or warranty relating to any financial
statements shall be deemed to be applicable to the financial statements most
recently delivered to the Banks in accordance with the provisions of the Loan

                               FOURTH AMENDMENT TO
                                CREDIT AGREEMENT

         THIS FOURTH AMENDMENT TO CREDIT AGREEMENT ("the "Amendment"), dated and
effective as of September 27, 1996, is made by and between MICRODYNE
CORPORATION, a Maryland corporation (the "Borrower"), CRESTAR BANK and NBD BANK
(the "Banks"), and CRESTAR BANK ("Crestar") as agent (the "Agent") for the
Banks.

                                    RECITALS

         The Borrower, the Banks and the Agent are parties to a Credit
Agreement, dated as of January 27, 1995, as amended by the First Amendment to
Credit Agreement, dated as of October 26, 1995, the Second Amendment to Credit
Agreement, dated as of June 30, 1996 (the "Second Amendment"), and the Third
Amendment to Credit Agreement, dated as of August 19, 1996 (as further amended,
modified or supplemented from time to time, the "Agreement").  Terms defined in
the Agreement shall have the same defined meanings when such terms are used in
this Amendment.

         The Borrower, the Agent and the Banks have agreed to amend certain
provisions of the Agreement. Accordingly, for valuable consideration, the
receipt and sufficiency of which are acknowledged, the Borrower, the Banks and
the Agent agree as follows:

         1.       The following definitions are added to Section 1.1 of
the Agreement:

                  "Applicable DC Advance Percentage" means the percentage
         approved by the Banks from time to time for purposes of determining the
         appropriate amounts of Eligible Data Communications Receivables to be
         included in the Borrowing Base. As of September 30, 1996, the
         Applicable DC Advance Percentage shall be 40%. If the average Dilution
         Rate is 20% or less for two successive fiscal quarters, the Banks will
         increase the Applicable DC Advance Percentage to 60%; provided,
         however, that if the Dilution Rate exceeds 20% for any subsequent
         fiscal quarter, the Banks may reduce the Applicable DC Advance
         Percentage to 40%. Notwithstanding the foregoing, if the Banks
         determine in their sole discretion at any time that the then-applicable
         percentage is not an appropriate percentage based on the Dilution Rate
         for a particular quarter, the Banks may lower the Applicable DC Advance
         Percentage to a level that they deem appropriate, but in no event to
         less than 20%. Each change in the Applicable DC Advance Percentage
         shall become effective on the next Business Day following written
         notice from the Agent to the Borrower.

                  "Dilution Rate" means, for any fiscal quarter, a fraction
         (expressed as a percentage), the numerator of which is the aggregate
         amount of cash and non-cash


<PAGE>   2



         credits issued to Customers of the Data Communications division during
         such quarter (including, without limitation, returns, stock rotation
         credits and billing adjustments), and the denominator of which is the
         gross sales of the Borrower for the immediately preceding fiscal
         quarter.

                  "Eligible Data Communications Receivables" means Eligible
         Receivables arising out of the operation of the Borrower's Data
         Communications division.

                  "Eligible Equipment" means machinery and equipment, in good
         and workable condition, to which the Borrower has title and in which
         the Banks have a first priority security interest, free and clear of 
         all other Liens, including, without limitation, any Liens arising out
         of Capital Leases; provided, however, that in no event shall Eligible
         Equipment include fixtures that form part of the Eligible Real Estate.

                  "Eligible Real Estate" means the Land and the building and
         fixtures located on the Land; provided, however, that such Land,
         building and fixtures shall not become Eligible Real Estate unless and
         until the Agent receives a mortgagee title insurance policy, issued by
         Ticor Title Insurance Company, in the amount of $5,000,000, insuring
         the Mortgage as a valid first Lien against the fee simple title to the
         Land and such buildings and fixtures, and containing no exceptions,
         printed form or otherwise, other than (a) real estate taxes not yet due
         and payable, (b) an exception for matters that would be disclosed by a
         current survey, and (c) the exceptions listed as items 4 through 14 in
         Section II of Schedule B of Attorney's Title Insurance Fund, Inc.
         Commitment No. C-2358100, dated September 13, 1996.

                  "Land" means Lots 23 through 38, inclusive, Block 722, Unit
         No. 29. Silver Spring Shores, Marion County, Florida, as the same are
         platted in Plat Book J, Pages 227 through 231, Public Records of
         Marion County, Florida.

                  "Value" means, with respect to the Eligible Real Estate (a)
         prior to the receipt and approval by the Banks of an appraisal of the
         Eligible Real Estate, the assessed value thereof, based on the Marion
         County, Florida real estate tax assessment, and (b) upon the receipt
         and approval by the Banks of such appraisal, 80% of the appraised value
         of the Eligible Real Estate; in either case, not to exceed $5,000,000.
         Any appraisal shall be ordered by the Agent and shall conform to the
         regulatory guidelines applicable to each Bank.

         2.       The following definitions contained in Section 1.1 of the
Agreement are deleted in their entirety and replaced with the following
provisions:

                  "Advance Commitment" means (a) from the date hereof until
         December 30, 1996, $12,148,500 in the case of Crestar and $5,351,500
         in the

                                        2



<PAGE>   3



         case of NBD; (b) as of December 31, 1996, and until March 30, 1997,
         $10,065,900 in the case of Crestar and $4,434,100 in the case of NBD;
         and (c) as of March 31, 1997, and until June 29, 1997, $5,553,600 in
         the case of Crestar and $2,446,400 in the case of NBD; and (d) as of
         June 30, 1997, and at all times thereafter, $3,471,000 in the case of
         Crestar and $1,529,000 in the case of NBD; provided, however that each
         Bank's Advance Commitment shall be reduced automatically by its
         Commitment Percentage of any Maximum Amount reduction resulting from a
         prepayment of the Advances pursuant to Section 2.10(e).

                  "Borrowing Base" means, at the time in question, the sum of
         the following: (a) Applicable DC Advance Percentage of Eligible Data
         Communications Receivables, plus (b) 80% of Eligible Billed Receivables
         that do not arise out of the Borrower's Data Communications division,
         plus (c) the applicable Inventory Component, plus (d) 30% of the net
         book value of Eligible Equipment, plus (e) the Value of the Eligible
         Real Estate, provided, however, that at no time shall the Borrowing
         Base attributable to the Inventory Component exceed the Borrowing Base
         attributable to clauses (a) and (b) of this definition.

                  "Eligible Receivables" means Accounts Receivable of the
         Borrower (a) that represent valid obligations incurred by a Customer
         for goods shipped or delivered or services completed under valid
         contracts of sale, lease or service that have been formally awarded to
         the Borrower and for which all required contract documents have been
         executed by the Customer and the Borrower and, in the case of Accounts
         Receivable owed by the Government, for which funds have been
         appropriated and allocated; (b) with respect to which the applicable
         goods have been delivered to and accepted by the Customer on an
         absolute sale basis and not on a bill and hold sale basis, a
         consignment sale basis, a guaranteed sale basis, a sale or return 
         basis or on the basis of any other similar understanding; (c) on which
         the Customer is not an Affiliate or Subsidiary of the Borrower; (d)
         with respect to which the Borrower has no knowledge or notice of any
         inability of the Customer to make full payment; (e) from the face
         amounts of which have been deducted all payments, setoffs, amounts
         subject to adverse claims made in writing to the Borrower, contractual
         allowances, bad debt reserves and other credits applicable thereto,
         (f) that are subject to no Liens other than those permitted by this
         Agreement; (g) that continue to be in full conformity with the
         representations and warranties made by the Borrower to the Banks in
         this Agreement and the Security Agreement; (h) with respect to which
         the Banks are and continue to be satisfied with the credit standing of
         the Customer; (i) on which the Customer is not a creditor of the
         Borrower, and (j) on which, unless an Acceptable Foreign Customer or
         otherwise approved by the Banks in writing, in their sole discretion,
         the Customer is not a Foreign Customer; provided, however, and without
         limiting any other provisions of this Agreement with respect to the
         exclusion of Receivables from the category of Eligible Receivables and
         the Borrowing Base,

                                        3



<PAGE>   4



         that (1) if either Bank reasonably determines that the collectibility
         of any Account Receivable makes it unacceptable for inclusion as an
         Eligible Receivable and gives written notice to the Borrower indicating
         the reasons for such determination, then such Account Receivable shall
         thereafter be excluded from the category of Eligible Receivables, (2)
         if more than 50% of the aggregate face amount of Accounts Receivable
         owed by a Customer other than the Government are aged more than 90 days
         from the date of the initial invoices, then all Accounts Receivable
         owed by such Customer shall be included in a separate line item on the
         Aging and shall be excluded from the category of Eligible Receivables,
         and (3) in no case shall Eligible Receivables include any Account
         Receivable representing or arising out of retainages, holdbacks,
         revenues recognized or costs incurred in excess of approved or allowed
         reimbursement rates, cost overruns, unauthorized work or work beyond
         the scope of a contract, rebillings or contracts secured by surety
         bonds.

                  "Inventory Component" means 20% of Eligible Inventory, valued
         at the lower of cost or market, but in no event shall the Inventory
         Component included in the Borrowing Base be more than $6,000,000.

                  "Maximum Amount" means, with respect to the Advances, (a) as
         of September 30, 1996, until December 30, 1996, $17,500,000, (b) as of
         December 31, 1996, and until March 30, 1997, $14,500,000, (c) as of
         March 31, 1997, and until June 29, 1997, $8,000,000, and (d) as of June
         30, 1997, and at all times thereafter, $5,000,000; provided, however,
         that the applicable Maximum Amount on any date shall be further reduced
         by the amount of the prepayment of the Advances required by Section
         2.10(e) of this Agreement.

                  "Termination Date" means September 30, 1997, any earlier date
         of termination in whole of the Commitments pursuant to Section 9.1, or
         any later date if the Termination Date is extended in the sole
         discretion of the Banks in accordance with Section 2.4.

         3.       Section 2.1(a) is deleted in its entirety and replaced
with the following:

                  "SECTION 2.1 The Advances.

                  (a) Each Bank severally agrees, subject to the terms and
         conditions of this Agreement, to make Advances to the Borrower from
         time to time on any Business Day during the period from the date hereof
         until the Termination Date in an aggregate amount not to exceed at any
         time outstanding the amount of such Bank's Advance Commitment. The
         aggregate outstanding amount of Advances shall not exceed the Maximum
         Amount at any time. With the limits of each Bank's Advance Commitment
         and up to the Maximum Amount, the Borrower may borrow, prepay pursuant
         to Section 2.10 and reborrow hereunder from the date of this Agreement
         until the Termination Date; provided, however, that no Advance will be
         disbursed by

                                        4



<PAGE>   5



         any Bank if, after such disbursement, the Borrower would be required to
         make a prepayment of the Obligations in accordance with the provisions
         of Section 2.10(d)."

         4.       The Borrower acknowledges and agrees that the term "Borrowing
Base Loans" means, at any time, the sum of (a) the aggregate of the principal
balances of the outstanding Advances, (b) the aggregate of the principal
balances of the outstanding Term Loans, and (c) the aggregate of the face
amounts of the outstanding Letters of Credit. Section 2.10(d) is amended to read
as follows:

                  "(d) The Borrower shall immediately prepay the Obligations to
         the extent that (1) the Borrowing Base is less than 75% of the
         outstanding Borrowing Base Loans at any time until December 30, 1996,
         (2) as of December 31, 1996, and until March 30, 1997, the Borrowing
         Base is less than 80% of the Borrowing Base Loans at any time, and (3)
         as of March 31, 1997, and at all times thereafter, the Borrowing Base
         is less than 100% of the outstanding Borrowing Base Loans at any time."

         5.       The Borrower agrees that it shall no longer have the right to
designate a Loan to be, continue a Loan as or convert a Loan into a Eurodollar
Rate Loan, and the provisions of Section 2.9 are no longer applicable. In
addition, Section 2.6 is deleted in its entirely and replaced with the
following:

                  "SECTION 2.6 Interest". The Borrower shall pay interest on the
         unpaid principal amount of each Advance and Term Loan, on each Interest
         Payment Date, at a rate per annum equal to the Base Rate plus 1%,
         adjusted daily when and as the Base Rate is changed."

         6.       The first sentence of Section 2.11 is deleted and replaced

PAYMENT OF THIS NOTE IS SUBORDINATED TO PAYMENT OF THE "SENIOR DEBT" AS DEFINED
HEREIN


                                COMMERCIAL NOTE




$3,035,000                                                        April 17, 1996


                  FOR VALUE RECEIVED, the undersigned (the "Borrower") promises
to pay to the order of NOVELL, INC., a Delaware corporation (the "Lender,"
which term shall include any holder of this Note) without offset, at the
Lender's office located at 2180 Fortune Drive, San Jose, California 95131 (or
at such other address as the Lender shall designate), the principal sum of
Three Million Thirty-five Thousand Dollars ($3,035,000), together with interest
on the principal balance outstanding from time to time at the rate provided in
this Note.

                  INTEREST RATE.  This Note shall bear interest on the
principal balance outstanding from time to time, from the date of this Note
until paid in full, at a fixed rate per annum of eight percent (8.0%). Interest
shall be computed on the basis of a 360 day year, counting the actual number of
days elapsed.


                  PAYMENT TERMS.  The Borrower agrees to pay this Note in
installments of $137,264.83 including interest, beginning May 17, 1996 and on
the same day of each consecutive month thereafter; provided, however,
principal, interest and all other charges shall be due and payable in full on
April 17, 1998.


                  PREPAYMENT.  The Borrower may pay the whole or any part of
the outstanding indebtedness evidenced by this Note at any time without penalty
by paying the principal amount to be prepaid together with accrued interest
thereon to the date of prepayment.  Any prepayment of principal shall not
affect the obligation of the Borrower to make subsequent scheduled principal
payments at the times and in the amounts required until this Note is paid in
full.




                                  Page 1 of 5
<PAGE>   8
                  DEFAULT.  Each of the following events or conditions shall
constitute a default ("Default") under this Note:

                  (a)     the failure to make any payment of principal,
interest or any other amount due under this Note within three (3) business
days from the date on which Borrower receives written notice from Lender that
such payment is due and unpaid;

                  (b)     the failure to perform or observe any warranty,
covenant, or other condition of this Note; or

                  (c)     the insolvency of the Borrower, the filing of a
petition by or against the Borrower under the provisions of any bankruptcy,
reorganization, arrangement, insolvency, liquidation or similar law for relief
of debtors, the appointment or application for appointment of any receiver for
the Borrower or the property of the Borrower, or an assignment for the benefit
of creditors by the Borrower.


                  ACCELERATION.  At the option of the Lender, upon the
occurrence of a Default as defined above, the full amount remaining unpaid on
this Note shall become immediately due and payable without presentment, demand
or notice of any kind; and the Lender may exercise any or all remedies
available to it under applicable law and the Loan Documents.


                  IMMEDIATELY AVAILABLE FUNDS.  The principal of and interest
on this Note shall be payable in immediately available funds in lawful money of
the United States which shall be legal tender for public and private debts at
the time of payment.


                  APPLICATION OF PAYMENTS.  Payments will be applied to
interest, principal, and late charges and other charges due at the time such
payments are received, in that order.  All payments shall be applied to
satisfaction of scheduled payments in the order in which they become due.


                  LATE CHARGE; ATTORNEYS' FEES.  If the Borrower fails to pay
any amount due under this Note within 15 days of the date due, the Borrower
shall pay to the Lender on demand a late charge equal to five percent (5%) of
the amount due.  The Borrower shall pay to the Lender on demand all reasonable
costs incurred by the Lender, and reasonable attorneys' fees, in the collection
or enforcement of this Note in the event of Default, whether or not suit is
brought.

                  SUBORDINATION.  The Lender hereby subordinates the payment of
this Note (the "Subordinated Debt") to the payment in full of all loans,
advances, liabilities and indebtedness now or hereafter owed by the Borrower to
Crestar Bank, a Virginia banking corporation (the "Bank") and all renewals,
extensions, and modifications thereof and substitutions therefor and all loans,
advances, liabilities and indebtedness now or hereafter owed by the Borrower to
NBD Bank under the Credit Agreement, dated as of January 27, 1995, among NBD
Bank, Crestar Bank and the Borrower, and all extensions, renewals and
modifications thereof and substitutions therefor, with respect to which Crestar
Bank acts as agent for NBD Bank (the "Senior Debt").  The Lender further agrees
that any lien, encumbrance or other security for the payment of the
Subordinated Debt, whether now existing or hereafter arising, is and shall be
expressly subordinated to any lien, encumbrance or other security for the
payment of the Senior Debt.

                  Notwithstanding the provisions of the preceding paragraph, as
long as no default has occurred under any instrument or agreement evidencing or
securing the Senior Debt, scheduled payments of principal, interest and fees on
the Subordinated Debt, and no other payments, may be received, accepted and
retained by the Lender; provided, however in no event will the Lender receive,
accept or retain any prepayment of the Subordinated Debt prior to the scheduled
due date.

                  The Lender agrees that until the Senior Debt is paid in full
it will not (i) ask, demand, sue for take or receive from the Borrower directly
or indirectly, in cash, securities or other property or by set-off or in any
other manner (including, without limitation, from or by way of collateral),
payment of all or any part of the Subordinated Debt, or (ii) commence or join
with other creditors in commencing any bankruptcy, reorganization, receivership
or insolvency proceeding against the Borrower.  In the event of any Default
described in paragraph (c) of the DEFAULT section of this Note, then and in any
such event the Bank and NBD Bank shall be entitled to receive payment in full
in cash or cash equivalents of all amounts due or to become due on or in
respect of all Senior Debt before the Lender shall be entitled to receive and
retain any payment on account of the principal, interest or other amounts due
or to become due on the Subordinated Debt, and to that end the Bank and NBD
Bank shall be entitled to receive, for application to the payment of the Senior
Debt, any payment or distribution of any kind or character whether in cash,
securities, or other property, which may be payable or deliverable in respect
of the Subordinated Debt in any such case, proceeding, dissolution, liquidation
or other winding up or event.  Accordingly, any payment or distribution of
assets of the Borrower of any kind or character which would otherwise have been
made to the Lender but for the provisions of this section shall instead be made
by the Borrower or by the trustee in bankruptcy, receiver liquidating trustee,
custodian, assignee, agent or other person making payment or distribution of
assets of the Borrower directly to the Bank and NBD Bank for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full in cash or cash equivalents after giving effect to any
concurrent payment or distribution to or for the benefit of the Bank and NBD
Bank.  The Lender irrevocably authorizes and empowers the Bank to file claims
and take such other actions, in the Bank's own name or in the name of the
Lender

                                  Page 3 of 5
<PAGE>   10
or otherwise, as the Bank may deem necessary or advisable for the enforcement
of this section of this Note, and to vote the full amount of the Lender's
claims in any receivership, insolvency or bankruptcy proceeding in the Lender's
place and stead.  The Under further irrevocably appoints the Bank its true and
lawful attorney-in-fact for the purposes specified herein, with full power of
substitution, and such power shall be a power coupled with an interest.  The
Lender further agrees to execute and deliver to the Bank such powers of
attorney, assignments or other instruments as may be reasonably requested by
the Bank in order to enable the Bank to enforce any and all claims upon or with
respect to any or all of the Subordinated Debt and to collect and receive any
and all payments or distributions which may be payable or deliverable at any
time upon or with respect to any of the Subordinated Debt.

                  If, notwithstanding the provisions of this section of this
Note, the Lender shall have received any payment or distribution of assets of
the Borrower of any kind or character before all amounts due or to become due
on or in respect of all Senior Debt have been paid in full in cash or cash
equivalents, then and in such event such payment or distribution shall be
received in trust for the Bank and NBD Bank and shall be forthwith paid over or
delivered by the Lender receiving the same directly to the Bank and NBD Bank or
to the extent legally required, to the trustee in bankruptcy, receiver
liquidating trustee, custodian, assignee, agent or other person making such
payment or distribution of assets of the Borrower for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full after giving effect to any concurrent payment or
distribution to or for the Bank and NBD Bank.

                  The Lender agrees that until the Senior Debt is paid in full
it will not subordinate any part of the Subordinated Debt to any indebtedness
owed to any person other than the Bank and NBD Bank.

                  The terms of this section of this Note shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Debt is rescinded or must otherwise be returned by the Bank
or NBD Bank upon the insolvency, bankruptcy or reorganization of the Borrower
or otherwise, all as though such payment had been due but not made at such
time.


                  ADDITIONAL TERMS.

                  The proceeds of this Note shall be used to acquire or carry
on a business, professional, investment, or commercial enterprise or activity.

                  The rights and remedies of the Lender under this Note, the
other Loan Documents, and applicable law shall be cumulative and concurrent,
and the exercise of any one or more of them shall not preclude the simultaneous
or later exercise by the Lender of any or all such other rights or remedies.
In the event any provision of this Note is held to be

                                  Page 4 of 5
<PAGE>   11
invalid, illegal, or unenforceable for any reason, then such provision only
shall be deemed null and void and shall not affect any other provisions of this
Note, which shall remain effective.

                  This Note shall be governed by and construed in accordance
with the laws of the Commonwealth of Virginia.

                  WITNESS the following signature and seal:

affect the obligation of the Borrower to make subsequent scheduled principal
payments at the times and in the amounts required until this Note is paid in
full.


                  DEFAULT.  Each of the following events or conditions shall
constitute a default ("Default") under this Note:

                                  Page 1 of 5
<PAGE>   15
                  (a)     the failure to make any payment of principal,
interest or any other amount due under this Note within three business days of
the date on which Borrower receives written notice from Lender that such
payment is due and unpaid;

                  (b)     the failure to perform or observe any warranty,
covenant, or other condition of this Note; or

                  (c)     the insolvency of the Borrower, the filing of a
petition by or against the Borrower under the provisions of any bankruptcy,
reorganization, arrangement, insolvency, liquidation or similar law for relief
of debtors, the appointment or application for appointment of any receiver for
the Borrower or the property of the Borrower, or an assignment for the benefit
of creditors by the Borrower.


                  ACCELERATION.  At the option of the Lender, upon the
occurrence of a Default as defined above, the full amount remaining unpaid on
this Note shall become immediately due and payable without presentment, demand
or notice of any kind; and the Lender may exercise any or all remedies
available to it under applicable law and the Loan Documents.


                  IMMEDIATELY AVAILABLE FUNDS.  The principal of and interest
on this Note shall be payable in immediately available funds in lawful money of
the United States which shall be legal tender for public and private debts at
the time of payment.


                  APPLICATION OF PAYMENTS.  Payments will be applied to
interest, principal, and late charges and other charges due at the time such
payments are received, in that order.  All payments shall be applied to
satisfaction of scheduled payments in the order in which they become due.


                  LATE CHARGE; ATTORNEYS' FEES.  If the Borrower fails to pay
any amount due under this Note within 15 days of the date due, the Borrower
shall pay to the Lender on demand a late charge equal to five percent (5%) of
the amount due.  The Borrower shall pay to the Lender on demand all reasonable
costs incurred by the Lender, and reasonable attorneys' fees, in the collection
or enforcement of this Note in the event of Default, whether or not suit is
brought.


                  SUBORDINATION.  The Lender hereby subordinates the payment of
this Note (the "Subordinated Debt") to the payment in full of all loans,
advances, liabilities and indebtedness now or hereafter owed by the Borrower to
Crestar Bank, a Virginia banking corporation (the "Bank") and all renewals,
extensions, and modifications thereof and

                                  Page 2 of 5
<PAGE>   16


substitutions therefor and all loans, advances, liabilities and indebtedness
now or hereafter owed by the Borrower to NBD Bank under the Credit Agreement,
dated as of January 27, 1995, among NBD Bank, Crestar Bank and the Borrower,
and all extensions, renewals and modifications thereof and substitutions
therefor, with respect to which Crestar Bank acts as agent for NBD Bank (the
"Senior Debt").  The Lender further agrees that any lien, encumbrance or other
security for the payment of the Subordinated Debt, whether now existing or
hereafter arising, is and shall be expressly subordinated to any lien,
encumbrance or other security for the payment of the Senior Debt.

                 Notwithstanding the provisions of the preceding paragraph, as
long as no default has occurred under any instrument or agreement evidencing or
securing the Senior Debt, scheduled payments of principal, interest and fees on
the Subordinated Debt, and no other payments, may be received, accepted and
retained by the Lender; provided, however in no event will the Lender receive,
accept or retain any prepayment of the Subordinated Debt prior to the scheduled
due date.

                 The Lender agrees that until the Senior Debt is paid in full
it will not (i) ask, demand, sue for take or receive from the Borrower directly
or indirectly, in cash, securities or other property or by set-off or in any
other manner (including, without limitation, from or by way of collateral),
payment of all or any part of the Subordinated Debt, or (ii) commence or join
with other creditors in commencing any bankruptcy, reorganization, receivership
or insolvency proceeding against the Borrower.  In the event of any Default
described in paragraph (c) of the DEFAULT section of this Note, then and in any
such event the Bank and NBD Bank shall be entitled to receive payment in full
in cash or cash equivalents of all amounts due or to become due on or in
respect of all Senior Debt before the Lender shall be entitled to receive and
retain any payment on account of the principal, interest or other amounts due
or to become due on the Subordinated Debt, and to that end the Bank and NBD
Bank shall be entitled to receive, for application to the payment of the Senior
Debt, any payment or distribution of any kind or character whether in cash,
securities, or other property, which may be payable or deliverable in respect
of the Subordinated Debt in any such case, proceeding, dissolution, liquidation
or other winding up or event.  Accordingly, any payment or distribution of
assets of the Borrower of any kind or character which would otherwise have been
made to the Lender but for the provisions of this section shall instead be made
by the Borrower or by the trustee in bankruptcy, receiver liquidating trustee,
custodian, assignee, agent or other person making payment or distribution of
assets of the Borrower directly to the Bank and NBD Bank for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full in cash or cash equivalents after giving effect to any
concurrent payment or distribution to or for the benefit of the Bank and NBD
Bank.  The Lender irrevocably authorizes and empowers the Bank to file claims
and take such other actions, in the Bank's own name or in the name of the
Lender or otherwise, as the Bank may deem necessary or advisable for the
enforcement of this section of this Note, and to vote the full amount of the
Lender's claims in any receivership, insolvency or bankruptcy proceeding in the
Lender's place and stead.  The Lender further irrevocably appoints the Bank its
true and lawful attorney-in-fact for the purposes specified



                                  Page 3 of 5
<PAGE>   17
herein, with full power of substitution, and such power shall be a power
coupled with an interest.  The Lender further agrees to execute and deliver to
the Bank such powers of attorney, assignments or other instruments as may be
reasonably requested by the Bank in order to enable the Bank to enforce any and
all claims upon or with respect to any or all of the Subordinated Debt and to
collect and receive any and all payments or distributions which may be payable
or deliverable at any time upon or with respect to any of the Subordinated
Debt.

                 If, notwithstanding the provisions of this section of this
Note, the Lender shall have received any payment or distribution of assets of
the Borrower of any kind or character before all amounts due or to become due
on or in respect of all Senior Debt have been paid in full in cash or cash
equivalents, then and in such event such payment or distribution shall be
received in trust for the Bank and NBD Bank and shall be forthwith paid over or
delivered by the Lender receiving the same directly to the Bank and NBD Bank or
to the extent legally required, to the trustee in bankruptcy, receiver
liquidating trustee, custodian, assignee, agent or other person making such
payment or distribution of assets of the Borrower for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full after giving effect to any concurrent payment or
distribution to or for the Bank and NBD Bank.

                 The Lender agrees that until the Senior Debt is paid in full
it will not subordinate any part of the Subordinated Debt to any indebtedness
owed to any person other than the Bank and NBD Bank.

                 The terms of this section of this Note shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Debt is rescinded or must otherwise be returned by the Bank
or NBD Bank upon the insolvency, bankruptcy or reorganization of the Borrower
or otherwise, all as though such payment had been due but not made at such
time.



                 ADDITIONAL TERMS.

                 The proceeds of this Note shall be used to acquire or carry on
a business, professional, investment, or commercial enterprise or activity.

                 The rights and remedies of the Lender under this Note, the
other Loan Documents, and applicable law shall be cumulative and concurrent,
and the exercise of any one or more of them shall not preclude the simultaneous
or later exercise by the Lender of any or all such other rights or remedies.
In the event any provision of this Note is held to be invalid, illegal, or
unenforceable for any reason, then such provision only shall be deemed null and
void and shall not affect any other provisions of this Note, which shall remain
effective.

                 SUBORDINATION.  The Lender hereby subordinates the payment of
this Note (the "Subordinated Debt") to the payment in full of all loans,
advances, liabilities and indebtedness now or hereafter owed by the Borrower to
Crestar Bank, a Virginia banking corporation (the "Bank") and all renewals,
extensions, and modifications thereof and substitutions therefor and all loans,
advances, liabilities and indebtedness now or hereafter owed by the Borrower to
NBD Bank under the Credit Agreement, dated as of January 27, 1995, among NBD
Bank, Crestar Bank and the Borrower, and all extensions, renewals and
modifications thereof and substitutions therefor, with respect to which Crestar
Bank acts as agent for NBD Bank (the "Senior Debt").  The Lender further agrees
that any lien, encumbrance or other security for the payment of the
Subordinated Debt, whether now existing or hereafter arising, is and shall be
expressly subordinated to any lien, encumbrance or other security for the
payment of the Senior Debt.

                 Notwithstanding the provisions of the preceding paragraph, as
long as no default has occurred under any instrument or agreement evidencing or
securing the Senior Debt, scheduled payments of principal, interest and fees on
the Subordinated Debt, and no other payments, may be received, accepted and
retained by the Lender; provided, however in no event will the Lender receive,

it will not (i) ask, demand, sue for take or receive from the Borrower directly

described in paragraph (c) of the DEFAULT section of this Note, then and in any
such event the Bank and NBD Bank shall be entitled to receive payment in full
in cash or cash equivalents of all amounts due or to become due on or in
respect of all Senior Debt before the Lender shall be entitled to receive and
retain any payment on account of the principal, interest or other amounts due
or to become due on the Subordinated Debt, and to that end the Bank and NBD
Bank shall be entitled to receive, for application to the payment of the Senior
Debt, any payment or distribution of any kind or character whether in cash,
securities, or other property, which may be payable or deliverable in respect

assets of the Borrower of any kind or character which would otherwise have been
made to the Lender but for the provisions of this section shall instead be made

custodian, assignee, agent or other person making payment or distribution of

Lender

of this section of this Note, and to vote the full amount of the Lender's
claims in any receivership, insolvency or bankruptcy proceeding in the Lender's
place and stead.  The Lender further irrevocably appoints the Bank its true and
lawful attorney-in-fact for the purposes specified herein, with full power of
substitution, and such power shall be a power coupled with an interest.  The
Lender further agrees to execute and deliver to the Bank such powers of
attorney, assignments or other instruments as may be reasonably requested by
the Bank in order to enable the Bank to enforce any and all claims upon or with
respect to any or all of the Subordinated Debt and to collect and receive any
and all payments or distributions which may be payable or deliverable at any
time upon or with respect to any of the Subordinated Debt.

                 If, notwithstanding the provisions of this section of this
Note, the Lender shall have received any payment or distribution of assets of
the Borrower of any kind or character before all amounts due or to become due
on or in respect of all Senior Debt have been paid in full in cash or cash
equivalents, then and in such event such payment or distribution shall be
received in trust for the Bank and NBD Bank and shall be forthwith paid over or
delivered by the Lender receiving the same directly to the Bank and NBD Bank or
to the extent legally required, to the trustee in bankruptcy, receiver
liquidating trustee, custodian, assignee, agent or other person making such
payment or distribution of assets of the Borrower for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full after giving effect to any concurrent payment or
distribution to or for the Bank and NBD Bank.

                 The Lender agrees that until the Senior Debt is paid in full
it will not subordinate any part of the Subordinated Debt to any indebtedness
owed to any person other than the Bank and NBD Bank.

                 The terms of this section of this Note shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Debt is rescinded or must otherwise be returned by the Bank
or NBD Bank upon the insolvency, bankruptcy or reorganization of the Borrower
or otherwise, all as though such payment had been due but not made at such
time.


                 ADDITIONAL TERMS.

other Loan Documents, and applicable law shall be cumulative and concurrent,
and the exercise of any one or more of them shall not preclude the simultaneous
or later exercise by the Lender of any or all such other rights or remedies.
In the event any provision of this Note is held to be

invalid, illegal, or unenforceable for any reason, then such provision only
shall be deemed null and void and shall not affect any other provisions of this
Note, which shall remain effective.

and all extensions, renewals and modifications thereof and substitutions
therefor, with respect to which Crestar Bank acts as agent for NBD Bank (the
"Senior Debt").  The Lender further agrees that any lien, encumbrance or other
security for the payment of the Subordinated Debt, whether now existing or
hereafter arising, is and shall be expressly subordinated to any lien,
encumbrance or other security for the payment of the Senior Debt.

                 Notwithstanding the provisions of the preceding paragraph, as
long as no default has occurred under any instrument or agreement evidencing or
securing the Senior Debt, scheduled payments of principal, interest and fees on
the Subordinated Debt, and no other payments, may be received, accepted and
retained by the Lender; provided, however in no event will the Lender receive,
accept or retain any prepayment of the Subordinated Debt prior to the scheduled
due date.

                 The Lender agrees that until the Senior Debt is paid in full
it will not (i) ask, demand, sue for take or receive from the Borrower directly
or indirectly, in cash, securities or other property or by set-off or in any
other manner (including, without limitation, from or by way of collateral),
payment of all or any part of the Subordinated Debt, or (ii) commence or join
with other creditors in commencing any bankruptcy, reorganization, receivership
or insolvency proceeding against the Borrower.  In the event of any Default
described in paragraph (c) of the DEFAULT section of this Note, then and in any
such event the Bank and NBD Bank shall be entitled to receive payment in full
in cash or cash equivalents of all amounts due or to become due on or in
respect of all Senior Debt before the Lender shall be entitled to receive and
retain any payment on account of the principal, interest or other amounts due
or to become due on the Subordinated Debt, and to that end the Bank and NBD
Bank shall be entitled to receive, for application to the payment of the Senior
Debt, any payment or distribution of any kind or character whether in cash,
securities, or other property, which may be payable or deliverable in respect
of the Subordinated Debt in any such case, proceeding, dissolution, liquidation
or other winding up or event.  Accordingly, any payment or distribution of
assets of the Borrower of any kind or character which would otherwise have been
made to the Lender but for the provisions of this section shall instead be made
by the Borrower or by the trustee in bankruptcy, receiver liquidating trustee,
custodian, assignee, agent or other person making payment or distribution of
assets of the Borrower directly to the Bank and NBD Bank for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full in cash or cash equivalents after giving effect to any
concurrent payment or distribution to or for the benefit of the Bank and NBD
Bank.  The Lender irrevocably authorizes and empowers the Bank to file claims
and take such other actions, in the Bank's own name or in the name of the
Lender or otherwise, as the Bank may deem necessary or advisable for the
enforcement of this section of this Note, and to vote the full amount of the
Lender's claims in any receivership, insolvency or bankruptcy proceeding in the
Lender's place and stead.  The Lender further irrevocably appoints the Bank its
true and lawful attorney-in-fact for the purposes specified

                                  Page 3 of 5
<PAGE>   27
herein, with full power of substitution, and such power shall be a power
coupled with an interest.  The Lender further agrees to execute and deliver to
the Bank such powers of attorney, assignments or other instruments as may be
reasonably requested by the Bank in order to enable the Bank to enforce any and
all claims upon or with respect to any or all of the Subordinated Debt and to
collect and receive any and all payments or distributions which may be payable
or deliverable at any time upon or with respect to any of the Subordinated
Debt.

                 If, notwithstanding the provisions of this section of this
Note, the Lender shall have received any payment or distribution of assets of
the Borrower of any kind or character before all amounts due or to become due
on or in respect of all Senior Debt have been paid in full in cash or cash
equivalents, then and in such event such payment or distribution shall be
received in trust for the Bank and NBD Bank and shall be forthwith paid over or
delivered by the Lender receiving the same directly to the Bank and NBD Bank or
to the extent legally required, to the trustee in bankruptcy, receiver
liquidating trustee, custodian, assignee, agent or other person making such
payment or distribution of assets of the Borrower for application to the
payment of all Senior Debt remaining unpaid to the extent necessary to pay all
Senior Debt in full after giving effect to any concurrent payment or
distribution to or for the Bank and NBD Bank.

                 The Lender agrees that until the Senior Debt is paid in full
it will not subordinate any part of the Subordinated Debt to any indebtedness
owed to any person other than the Bank and NBD Bank.

                 The terms of this section of this Note shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Senior Debt is rescinded or must otherwise be returned by the Bank
or NBD Bank upon the insolvency, bankruptcy or reorganization of the Borrower
or otherwise, all as though such payment had been due but not made at such
time.



                 ADDITIONAL TERMS.

                 The proceeds of this Note shall be used to acquire or carry on
a business, professional, investment, or commercial enterprise or activity.

                 The rights and remedies of the Lender under this Note, the
other Loan Documents, and applicable law shall be cumulative and concurrent,
and the exercise of any one or more of them shall not preclude the simultaneous
or later exercise by the Lender of any or all such other rights or remedies.
In the event any provision of this Note is held to be invalid, illegal, or
unenforceable for any reason, then such provision only shall be deemed null and
void and shall not affect any other provisions of this Note, which shall remain
effective.

                                    RECITALS

  In the course of the distribution and sale of its products, Epson requires
product and subassembly repair and refurbishment, warranty administration,
product upgrade projects, telephone technical support, and other miscellaneous
Services.  Epson has determined that it is in its best interest to contract for
personnel to perform these Services, and Microdyne desires to provide personnel
to perform these Services on an independent contractor basis.  Additionally,
Epson and Microdyne wish to terminate the previous Depot Repair, Product
Refurbishment, and Warranty Administration Agreement, dated December 13, 1990,
and replace it with this Agreement to reflect current Epson requirements,
working conditions, and revised pricing.  The Depot Repair, Product
Refurbishment, and Warranty Administration Agreement, dated December 13, 1990,
and all its amendments, including Amendment 1, dated September 1, 1991,
Amendment 2, dated October 2, 1992, Amendment 3, dated December 1, 1992,
Amendment 4, dated May 1, 1993, Amendment 5, dated December 1, 1993, and
Amendment 6, dated October 1, 1994, are cancelled, terminated, and superseded
by this Agreement.

  1 . TERM.

      Five years effective April 1, 1996.

  2.  MICRODYNE PROVISION OF PERSONNEL AND SERVICES.

      Microdyne will provide qualified personnel to perform depot repair of
      products and subassemblies, product refurbishment, product upgrade
      projects, warranty administration, telephone technical support, and other
      miscellaneous Services (collectively called "Services") as requested by
      Epson.  The type and quantity of personnel and Services requested by
      Epson are subject to change from time to time to meet Epson's business
      needs.  Some Services may be performed by Epson personnel or by other
      independent contractors retained by Epson.  The Services performed by
      Microdyne will be mutually agreed upon and identified in writing, signed
      by the parties."

             Statement of Work, Attachment A hereto).  Epson retains full
             management control over its service terms and programs, as well as
             Epson's customer and end user relations.  For all practical
             purposes, Microdyne's provisions of the Services shall be
             invisible to Epson's customers and end users.

             methodologies that may result in increased Epson customer service
             and/or cost reductions.

             Epson will provide, at no charge to Microdyne, ongoing training
             for new Epson products to enable Leased Employees to perform the
             Services.

      2.4    Facilities and Equipment.

             Services will be performed at Epson's facilities currently located
             in Torrance and Carson, California, and Indianapolis, Indiana, and
             other locations as mutually agreed upon in writing, signed by the
             parties.  Epson will provide use of these facilities and all
             equipment, tools, test equipment, documentation, and supplies
             needed for the Services at no charge to Microdyne.  Both parties
             shall have a mutual and affirmative obligation to maintain the
             integrity and security of all facilities and equipment.  Both
             parties will take all reasonable steps to assure the security of
             the facilities and their contents.  Microdyne will reimburse Epson
             for any damage or loss caused by negligence on the part of
             Microdyne.

      2.5    Insurance.

             Microdyne shall indemnify, defend and hold Epson, its employees
             and affiliates harmless from any and all damages, liabilities,
             costs and expenses incurred by Epson as a result of any claims,
             judgments, or adjudication against Epson for any breach by
             Microdyne of the provisions of this Agreement or





                                       3
<PAGE>   4


             arising from any misconduct or negligence of Microdyne's employees
             in the scope of their employment.  Epson shall indemnify, defend
             and hold Microdyne, its employees and affiliates harmless from any
             and all damages, liabilities, costs and expenses incurred by
             Microdyne as a result of any breach of this Agreement by Epson,
             arising out of processes or procedures required by Epson or
             arising from any misconduct or negligence of Epson's employees in
             the scope of their employment.

             To support these indemnities, Microdyne and Epson will obtain and
             maintain in effect at all times contractual liability insurance in
             support of this agreement.  Epson will be named as an additional
             insured and policy limits should not be less than $1 million per
             occurrence and $10 million total.  Evidence of insurance will be
             provided to Epson within thirty (30) days of each policy renewal
             by Certificate of Insurance.

             Microdyne's insurance policies will waive any and all subrogation
             against Epson.

      2.6    Operating Assets and Equipment.

             During the course of the previous agreement, Microdyne purchased
             some assets and equipment as described in Attachment D. These
             assets and equipment will continue to be owned and used by
             Microdyne as required with no additional charge to Epson.

      2.7    Parts, Inventory, and Ordering.

             Epson will provide all parts necessary for the Services at no cost
             to Microdyne.  Microdyne will order parts from Epson on an as
             needed basis in conformance with Epson's existing parts and
             accounting procedures.

      2.8    Records and Audit Rights.

             (a)  Microdyne agrees to keep and maintain commercially reasonable
                  records of the charges associated with Microdyne's provision
                  of the Leased Employees and Services.  Epson retains the
                  right to have a representative of Epson's certified public
                  accounting firm inspect and audit Microdyne's books and
                  records pertaining to the





                                       4
<PAGE>   5
                  Leased Employees and Services upon notice to Microdyne, at
                  Epson's expense, to insure compliance with the terms of this
                  agreement.  If the audit at Epson's expense reveals
                  deficiencies greater than 2% of billing, then the cost of the
                  audit will be paid by Microdyne.

             (b)  Microdyne agrees to furnish to Epson a statement within
                  fifteen (15) days following the end of each month identifying
                  the Services performed during the preceding month and labor
                  expended.  Microdyne shall keep and maintain true and
                  accurate records regarding all information and data
                  reasonably necessary or required for the computation and
                  verification of all amounts payable to Microdyne hereunder.

             (c)  Microdyne agrees to provide any information required by Epson
                  to comply with government rules and regulations.  The
                  information will be made available on a mutually agreeable
                  schedule determined at the time of any request.

      2.9    Product Safety.

             Microdyne agrees to notify Epson immediately in writing upon
             discovery that any Epson product fails to comply with any
             applicable consumer product or electrical safety law or
             regulation, or upon discovery that any such product contains a
             defect which could, in the reasonable opinion of Microdyne, create
             a substantial operational problem or consumer product safety or
             electrical hazard.

      2.10   Failure to Perform.

             (a)  If Epson determines that Microdyne has consistently failed to
                  meet the mutually agreed upon quality and performance
                  standards for Services and Leased Employees, described in
                  Attachment A.II.A. and B., Epson will notify Microdyne in
                  writing of such discrepancies.  Microdyne will have 15 days
                  to develop a written plan of corrective action to meet
                  quality and performance standards.  Upon approval of the
                  corrective action plan by Epson, Microdyne will have 60 days
                  to restore Services or Leased Employees to quality and
                  performance standards.





                                       5
<PAGE>   6
             (b)  Additionally, if Epson executive management determines that
                  any Leased Employee has significantly failed to meet quality
                  or performance standards, or performed any other detrimental
                  act, Epson at its sole discretion may request that Microdyne
                  immediately replace that Leased Employee and Microdyne will
                  comply.

             (c)  Any personnel actions, including reductions in staff or
                  terminations, performed as a result of 2.10. a. or b. above
                  will be Microdyne's sole responsibility as defined in 2.1
                  above.

3.    USE OF EPSON TRADEMARKS AND LOGOS.

      During the term of this agreement, Microdyne is authorized to use the
      Epson trademarks, proprietary logos, and designations applicable to the
      products as may be necessary for Microdyne to provide the Services, in
      conformity with Epson's written guidelines for trademark usage.  Upon
      expiration or termination of this agreement, Microdyne shall cease all
      references and use of any and all Epson names, trademarks, logos, and

             applicable rights and patents, copyrights and trade secrets in
             Epson's products shall remain with Epson, and Microdyne agrees to

             agrees to take appropriate action by instructions or agreement
             with its employees, agents, and contractors who are permitted
             access to the Epson products or other proprietary information to

             with the repair and refurbishment criteria for the applicable
             service provided by Epson, and industry standards.  In the event

             a period of ninety (90) days after shipment thereof by Epson to a

      whichever is applicable.  Further, Microdyne reserves the right to
      suspend all Services provided under this agreement or require payment in
      advance in the event any two consecutive invoices are not paid in full
      within forty-five (45) days after the second invoice date.

      The charges identified herein in Attachment C shall be reviewed and
      negotiated, for the next twelve (12) month period, commencing ninety

             from the nonbreaching party.  This agreement shall automatically
             be cancelled if either party becomes insolvent or makes an
             assignment for the benefit of creditors or if any insolvency
             proceeding is initiated by or against it. All unpaid charges

<PAGE>   19
      2.     Epson will specify in writing the quantity of temporary or part
             time Microdyne employees requested by job description and will
             estimate the duration of the requirement.  Epson will make a best
             effort to provide a minimum of two (2) days advance notice for
             increases and one (1) day advance notice for decreases.

      3.     Epson will provide 65 days advanced notice for any decrease in
             Leased Employee staffing levels which may trigger the requirements
             of the Workers Adjustment and Retraining Notification Act of 1988.

      4.     All changes to requested staff levels require approval by Epson
             executive management or authorized Epson management.

  D.  Monthly Charges (Based on Rates in Table 1)

      1.     Full Time Employees, Salaried:

             a.   Charges will be at a monthly flat rate per employee based on
                  the applicable pay grade.

             b.   Epson will not be charged for full time, salaried employees
                  who are absent due to short or long term disability, leave of
                  absence, or jury duty; nor will these absences be counted
                  against Microdyne attendance percentages.

             c.   Microdyne will be expected to maintain acceptable levels of
                  full time, salaried employee attendance as follows:

<TABLE>
                  <S>                                         <C>
                  # Salaried employee days worked in month    = Monthly Attendance %
                  ----------------------------------------
                  # Salaried employees x # work days in month
</TABLE>


                  A rolling six month minimum monthly attendance average of 94%
                  must be maintained for the immediate preceding six months.
                  In any month where the six month average falls below 94%, the
                  monthly invoice will be reduced in percentage by the amount
                  that the six month average is below 94%.  For example, a six
                  month average attendance percent of 92.5% would cause a 1.5%
                  decrease in the invoice for that month.





                                       2
<PAGE>   20
      2.     Full Time Employees, Hourly:

             Billing will be for actual hours worked based on the applicable
             pay grade.  All other hours and payments are excluded.

      3.     Temporary and Part-Time Employees, Hourly:

             Billing will be for actual hours worked on a cost plus basis.  All
             other hours and payments are excluded.

      4.     Volume Discount:

             A volume discount will be applied to the total monthly invoice
             amount.

  E.  Overtime Authorization.

      For each operational area, Epson will authorize Microdyne the authority
      to work a reasonable amount of overtime sufficient to provide operational
      flexibility.  Overtime in excess of this amount must be approved in
      advance by Epson.

  F.  Pricing Equity.

      1      Microdyne will insure that all Leased Employees meet or exceed
             minimum job description qualifications for their assigned job and
             pay grade as charged to Epson, and that actual pay rates for
             Leased Employees will meet or exceed the low pay range of the pay
             grade charged to Epson for that Leased Employee.

      2.     Microdyne will further insure that it hires and administers Leased
             Employee salaries within the guidelines of Microdyne's employee
             policies and procedures, meeting reasonable industry standards.

  G.  Skill Range Progression.

      1.     Certain jobs have skill range progressions, e.g., technicians, TTS
             representatives.  Microdyne and Epson will agree on the desired
             number of employees at each skill level.

      2.     Microdyne may be unable to provide sufficient qualified personnel
             to meet the agreed upon skill level allocation.  If this occurs
             Microdyne, with Epson's approval, may elect to provide Leased
             Employees at a lower skill level, charging at the appropriate
             lower pay rate.  At some time, some of these Leased Employees may
             have increased their skills to meet the job description
             requirements for the next higher pay rate.  Microdyne may promote
             these Leased Employees to a higher pay grade and increase charges
             to Epson, subject to Epson's agreement that the Leased Employee
             meets job description requirements and is within the skill level
             allocation stated in Gl.

  H.  Other Charges.

      1 .    Epson may request travel for non-management Leased Employees or
             special travel for management Leased Employees.  Microdyne will
             insure travel expenses are incurred within Microdyne's travel
             expense policies, and will invoice Epson for actual charges.  No
             charges will be invoiced for normal business travel by Microdyne
             management employees.

      2.     Epson will pay directly for all outside vendors, services, and
             temporary agency personnel utilized in performing Services.

      3.     No other charges will apply.

                  CONFIDENTIALITY AND NON-DISCLOSURE AGREEMENT



This Agreement is made as of the 1st day of April, 1996, by and between Epson
America, Inc., a California corporation with its principal place of business at
20770 Madrona Avenue, Torrance, California 90509 ("Epson") and Microdyne
Corporation, a Virginia corporation located at 3601 Eisenhower Avenue,
Alexandria, Virginia 22304 ("Microdyne").

Whereas Epson will disclose to Microdyne certain information relating to its
products, parts, customers, and business practices for the purpose of enabling
Microdyne to perform various maintenance, repair, and distribution services
pertinent to certain Epson products and sub-assemblies sold by Epson and its
other appointees in the marketplace. Epson desires that any confidential and/or
proprietary information ("Information") disclosed to Microdyne be used only to
further the business relationship between the parties hereto.

In order to ensure that the information disclosed by Epson to Microdyne is used
only in accordance with the purposes stated above, the parties agree to the
following:

         I.       This Agreement shall be in effect for five (5) years.

         II.      Microdyne shall prevent the disclosure to others of
                  Information transmitted to Microdyne where such
                  Information is prominently designated as confidential,
                  and is disclosed in the performance of, or in
                  connection with, Microdyne services performed for
                  Epson.  Any Information delivered by Epson to Microdyne
                  marked "secret", "confidential", or with words of
                  similar meaning, shall be conclusively deemed, as
                  between the parties, confidential and trade secret
                  information of Epson.  Any Information not bearing such
                  marking shall not, however, be deemed to be non-secret
                  or non-confidential, but any such unmarked information
                  shall be subject to the same restrictions as contained
                  herein.

         III.     Epson warrants that no restriction is made upon

         IV.      Microdyne shall not use such confidential information
                  itself, disclose it to others to permit the disclosure
                  of such information to others, and will prevent
                  Microdyne employees (so long as they shall remain
                  employed by Microdyne) from divulging, publishing, or
                  using such information, except as is necessary to
                  perform the aforementioned maintenance repair and
                  distribution services.

         V.       All information disclosed by Epson to Microdyne shall remain
                  the property of Epson. At Epson's request, the tangible
                  information from Epson shall be promptly returned or
                  destroyed, together with all copies thereof. Upon request,
                  Microdyne shall provide written certification of the
                  destruction.

         VI.      Any notice or other communication provided under this
                  Agreement will be in writing and be sent via facsimile,
                  or certified or registered mail, return receipt
                  requested, to the respective addresses as either party
                  has designated to the other by notice in writing.  Any
                  such notice will be deemed given when received by the
                  other party, attention directed to the individual
                  singing this Agreement.

         VII.     This Agreement will be governed by the laws of the
                  State of California and constitutes the entire
                  Agreement between Epson and Microdyne pertaining to the
                  subject matter hereof.  No provisions of this Agreement
                  will be deemed waived, amended, or modified by either
                  party unless such waiver, amendment, or modification be

                  sought to enforce the waiver, amendment, or
                  modification.  If any provision of this Agreement is
                  held to be illegal or unenforceable, such shall not
                  effect the balance thereof.

         VIII.    The parties hereto acknowledge that they have read this
                  Agreement, understand it, and agree to be bound by its terms
                  and conditions. Further, the parties acknowledge that this
