                                    PART I

ITEM 1.  DESCRIPTION OF BUSINESS

     Benthos, Inc. (the "Company") was founded in 1962 to act as a manufacturer
of oceanographic products. It was incorporated as a Massachusetts corporation in
1965. Over the last 37 years, the Company has developed and acquired new
technology and products. Currently, the Company consists of two distinct
divisions: the Undersea Systems Division and the Container Inspection Systems
Division.

     Historically, the Company has focused its efforts on the Undersea Systems
marketplace with particular emphasis placed on the military and government
markets. Early in the 1990's, funding for these markets declined and the
Company's sales to these markets suffered a corresponding reduction. As a
result, the Company shifted its priorities to business development efforts in
commercial markets. These markets include the geophysical industry, where the
Company's hydrophone products are used in the search for oil and gas deposits
offshore, as well as the scientific research, nuclear inspection and
environmental markets. Also as a result of these efforts, added resources were
applied to the Company's Container Inspection Systems Division. A series of new
products was introduced and these products gained rapid acceptance into major
market segments such as the beer and beverage markets. The Company plans to
continue its emphasis on these markets into the future independent of any
recovery in the levels of government funding for the military market.

     In August, 1999, the Company acquired substantially all of the assets of
Datasonics, Inc., a manufacturer of acoustic based oceanographic products. The
Datasonics product lines are complementary to the Company's traditional undersea
products and are sold to many of the same customers and through substantially
the same product distribution system. The Company is in the process of
integrating the business acquired from Datasonics into its current operations.

     The Company's wholly-owned subsidiary, Benthos International, Inc. acts as
a foreign sales corporation (FSC) for the Company's foreign sales. It has no
substantial assets, liabilities or income.

                                       3

Undersea Systems Division

     The Company's Undersea Systems Division designs, develops, manufacturers
and sells products and services used in oceanographic and underwater
environments. The markets for these products include oceanographic research, oil
and gas exploration and production, hydrographic survey, nuclear power
generation, and underwater relocation, marking and navigation. The product range
includes acoustic transponders used for location marking and navigation,
acoustic release devices used for recovering instrumentation packages from the
depths of the ocean, optical imaging systems (including video, 35mm and digital
still cameras), hydrophones used for geophysical exploration and sound
detection, remotely operated vehicles for inspection and light work tasks and
glass flotation products used to house instruments and to provide buoyancy. The
product lines acquired from Datasonics include side scan sonars and sub bottom
profilers used for sea bed imaging, acoustic modems used to transmit digital
data underwater, and acoustic pingers used to locate and mark objects lost
underwater such as aircraft flight data and voice recorders. The Company's
undersea products are generally marketed under the trade name "Benthos." The
Company may also continue to use the "Datasonics" name for certain products.

Container Inspection Systems Division

     The Company's Container Inspection Systems Division designs, develops,
manufactures and sells systems used to inspect the integrity of containers in
the food, pharmaceutical and beverage industries. The customers for these
systems include manufacturers of food, beverages and pharmaceuticals packaged in
bottles, cans, glass jars, plastic containers and assorted vacuum packages with
metal and plastic caps. These systems are marketed under the trade name
"TapTone." TapTone systems integrate various sensor technologies with digital
signal processing techniques in order to inspect containers for leakage, seal
integrity, low or high pressure or vacuum, and similar packaging defects.
TapTone systems may be used on-line as continuous inspection systems that
operate at production speeds or as off-line inspection systems to periodically
validate package integrity.

1.   Principal Products

Undersea Systems

     The Company's undersea products and services are divided into nine distinct
groups as follows:

     a.   Acoustics

     The Acoustics product group includes transponders, acoustic releases and
companion deck control systems, and altimeters. Transponders are used to
transmit and receive acoustic signals underwater for the purposes of determining
location, navigation, or sending and receiving data. These products are used for
scientific

                                       4
<PAGE>

research, salvage and ship positioning operations. Both expendable and
recoverable products are manufactured. The transponder line includes low cost
versions that transmit a limited signal selection in response to a command
received, as well as more sophisticated versions that can be programmed to
transmit a wide variety of functions in response to received commands.
Transponders are monitored by and communicate with companion deck units which
are typically located on board a ship.

     Acoustic releases are sound-operated devices that will anchor underwater
products in place and will release those products, allowing them to float to the
surface, in response to an acoustic command signal transmitted from the surface.
The acoustic release product line includes both deep water (up to 12,000
meters), heavy duty, releases as well as shallow water (up to 600 meters), light
duty, low cost releases. Releases may be operated with companion deck control
units.

     Altimeters are used to determine the distance from the seabed to an object
or vehicle in the water column.

     b.   Hydrophones

     Hydrophones are underwater sensors designed to produce an output signal in
response to an acoustic pressure signal. They can be thought of as underwater
microphones. The Company's hydrophone products are typically used in the
offshore oil and gas exploration industry, where they listen to acoustic sound
waves generated by the reflections of an acoustic signal as it bounces off of
the various geological layers beneath the ocean floor. These data are used to
generate information about the geological structure beneath the ocean as a means
of locating promising oil and gas exploration sites. The Company's hydrophone
product line is also used in military applications to listen for and detect
submarines and other vessels under and on the surface of the ocean. Hydrophones
may also be sold to research institutions for various applications such as
listening to marine animals.

     The Company's hydrophone product line includes sophisticated versions that
offer high sensitivity and can operate at great depth without significant
variation in response, as well as low cost hydrophones for the seismic research
industry that are produced in high production volumes. The Company's hydrophone
products may be used with companion amplifiers that convert the electrical
signals to usable formats and they may be integrated into arrays, which are
groupings of hydrophones assembled together in long tubes for the purpose of
added acoustic sensitivity and for listening to acoustic signals over a long
distance.

     c.   Imaging

     The imaging products group consists of a line of cameras that are packaged
in enclosures that allow them to operate at varying depths underwater. The
Company's capabilities include still cameras (typically 35 mm), video cameras,
and digital still cameras

                                       5
<PAGE>

that can capture an image comprised of digital data for transmission to the
surface and subsequent processing by software. The Company also sells companion
underwater camera flashes and lights.

     The Company's imaging products are used in research to photograph
underwater wildlife and geological formations. Imaging products are also used in
the commercial market to photograph underwater structures, such as oil rigs and
shipwrecks, for the purposes of inspection. Imaging products are also employed
in military applications to remotely inspect underwater objects such as mines.

     d.   Remotely Operated Vehicles (ROVs)

     ROVs are unmanned underwater vehicles that are controlled from the surface
by a skilled operator. The Company's ROV product line includes a number of
specialized designs that are aimed at specific markets. These markets include
the research sector, where ROVs may be used as a camera delivery system for
visual documentation and inspection. ROVs are also sold to the nuclear power
industry, where they are used to perform inspections and light work tasks in
radioactive cooling water pools, and to the military sector, where they may be
used for remote inspection and to retrieve or deliver objects. The Company's ROV
products are also used for sewer and pipeline inspection. ROV systems are
occasionally used by the entertainment industry.

     e.   Glass Flotation

     The Company manufactures a line of glass spheres that are used to provide
buoyancy to underwater products and systems and may be used to house underwater
instruments and electronics, such as transponders. Glass spheres are offered in
three sizes depending on the individual requirements of buoyancy and/or housing
size. The Company also customizes its glass spheres for individual customer
requirements by providing various penetrations, machined surfaces and electrical
connectors. The Company pressure tests all of its glass sphere products in order
to insure successful operation at desired depths. Glass spheres are normally
provided with companion plastic "hard hats" that allow for protection of the
glass from breakage and for safe transport.

     f.   Acoustic Modems

     Acoustic modems are used to send and receive digital data underwater using
sound as the transmitting signal. The Company manufactures several different
configurations of modems dependent on the specific requirements of the
applications. Underwater acoustic modems utilize a sending and/or receiving
transducer, suitable digital electronics for coding and decoding the acoustic
signals and proprietary software algorithms to enable the modems to work in the
underwater environment.

                                       6
<PAGE>

     g.   Relocation Pingers

     Relocation pingers are small acoustic transmitters that operate in water
and produce a steady acoustic signal. Using a suitable receiver, an underwater
object equipped with a relocation pinger may be located by listening for the
pinger's pressure-emitted signal. Relocation pingers are most commonly installed
on commercial and military flight data and voice recorders but may also be used
on other objects such as torpedoes, remotely operated vehicles and shipping
containers.

     h.   Side Scan Sonar Systems and Sub Bottom Profilers

     Side scan sonar systems consist of an underwater towed body, commonly
referred to as a "towfish" and an electronic control and display package. The
towfish emits an acoustic signal while it is being towed and then listens for
the signal's reflections which are generated by objects on the sea floor. These
echoes are then manipulated electronically and by software and used to generate
an image of the sea floor. Side scan sonars are commonly used to conduct
underwater surveys in order to plan the routing of pipes and cables, locate
shipwrecks and similar objects and determine the overall structure and nature of
the ocean bottom.

     Sub bottom profilers also utilize a towfish and topside electronic control
and display devices. The towfish emits acoustic signals which penetrate the
surface of the sea floor. Some of the acoustic energy is reflected back and
received by the towfish. These reflected signals are processed electronically
and by software and are used to generate a visual image of the structure beneath
the sea floor. Sub bottom profilers are used to locate buried objects such as
shipwrecks, shallow mineral deposits and to aid in hydrographic surveys by
providing information about the seabed structure.

     i.   Contract Research and Engineering Services

     The Company periodically performs research under contract and custom
engineering design for both commercial and government agencies. Generally these
contract research and development activities support the Company's primary
product development efforts and are used to offset a portion of the costs
associated with advanced research and development. Revenues from these
activities have not been significant.

Container Inspection Systems

     The Company's container inspection systems are used to inspect bottles,
cans and similar packages for a variety of defects. The TapTone product line
includes the following:

                                       7
<PAGE>

     a.   TapTone II Pressure/Vacuum Discriminator

     TapTone II uses acoustic technology to test for acceptable levels of
pressure or vacuum in containers that have metal closures and/or are metallic
themselves (such as beverage cans, glass bottles with metal crowns, and
conventional steel cans). These data are used to determine if the tested package
meets preset quality acceptance criteria. TapTone II is used for a variety of
food processing and beverage applications and its principal market is the
brewing and beverage industry. The TapTone II system is an on-line, high speed
inspection system designed to test 100% of the containers on a production line
and to reject containers that are determined to be defective. A typical TapTone
II system consists of a sensor assembly, an electronic control and display unit,
and a rejector for removing defective containers from the production line.
TapTone II is also available in a case configuration which incorporates multiple
sensors for testing products that have been packaged in sealed cases.

     b.   TapTone 100

     The TapTone 100 system is a low cost universal inspection system that uses
a proximity sensor to measure the deflection of the metal lid on a container.
These data are used to determine if the container meets preset quality
acceptance criteria based upon lid deflection and its correlation with the
pressure or vacuum inside the container. TapTone 100 systems are normally used
to inspect steel and aluminum cans. TapTone 100 systems are on-line, high speed
inspection systems designed to test 100% of the containers on a production line,
rejecting containers that are determined to be defective. TapTone 100 systems
are self contained inspection systems and may be fitted with a variety of
optional sensors for additional inspections such as label presence, cocked cap
and missing cap.

     c.   Turbo Tracker

     The Turbo Tracker system uses a proximity sensor and digital signal
processing to measure the deflection of the metal lid on a container. These data
are used to determine if the container meets preset quality acceptance criteria
based upon lid deflection and its correlation with the pressure or vacuum inside
the container. A typical Turbo Tracker system consists of a sensor assembly, an
electronic control and display unit, and a rejector for removing defective
containers from the production line. The Turbo Tracker is also available in a
case configuration.

     d.   Laser Tracker

     The Laser Tracker system is similar to the Turbo Tracker system except that
it uses a laser beam to measure closure deflection on a container with a non-
metallic lid or closure. These data are correlated with pressure or vacuum
inside the container and are used to determine container quality based upon
preset criteria.

                                       8
<PAGE>

     e.   Squeezer

     The Squeezer mechanically deforms a resilient container with a preset
force. These data are used to determine if the container is leaking based upon
preset criteria. Squeezers are typically used on squeezable packages, such as
plastic bottles, jugs, and pouches.

     f.   Ray TRAK

     Ray TRAK is an X-ray based container inspection system used to determine if
containers are filled to the correct level. The inspection system illuminates
the container with an X-ray beam as it passes through the Ray TRAK. A detector
measures the X-ray radiation that passes through the container and correlates
that signal to the level of material in the container. The system can be
configured to detect underfills, overfills, or both. Containers such as steel
cans, aluminum beverage cans, bottles and jars are used with Ray TRAK.

     g. TapTone 500

     The Company introduced the TapTone 500 inspection system during fiscal year
1999. The TapTone 500 system is an upgraded inspection platform designed to
eventually replace the current TapTone II acoustic inspection system and the
current Turbo Tracker system. The TapTone 500 system incorporates several
improvements over the Company's existing products and may be integrated with a
variety of optional sensors to accommodate additional inspections. The first
version of the TapTone 500 system designed for pressure or vacuum discrimination
in cans was introduced during the year and additional versions are planned for
the future.

2.   Distribution and Marketing Methods

     The Undersea Systems Division and the Container Inspection Systems Division
market their products through an international network of independent sales
representatives and distributors. Sales representatives and distributors are
located in North America, South America, Europe, the Far East, Africa and
Australia. Domestic and international customers may also order the Company's
products directly from its headquarters in Massachusetts. Both divisions of the
Company participate in a number of trade shows and exhibitions around the world.
The Company also maintains an internal staff of trained sales and marketing
personnel with experience and expertise in the markets served by the Company.

3.   New Products.

     During fiscal year 1999 the Company introduced the TapTone 100 low cost
universal inspection system. This addition to the TapTone product line is
designed to meet the inspection requirements of the domestic and international
food canning markets. The Company also introduced the TapTone 500 inspection
controller, designed to form a foundation for future inspection systems.

4.   Competition

     Undersea Systems Division

     The Company competes with a variety of companies in various product
markets. The Company's policy is to compete based upon technical superiority and
quality and to differentiate itself through strong post-sale support. The
Company also has a policy of pursuing patent protection for its products when
possible. The Company also competes by providing customers with well trained
field service and application engineering support.

     In some markets, such as glass flotation and geophysical hydrophones, the
Company is one of the larger participants in the market. In other markets, such
as ROV systems, the Company is a minor participant and competes with larger,
well established companies that have significantly more resources than the
Company.

     A partial listing of competitors for the various markets in which the
Company competes appears below:

     Product Market                      Competitor(s)

     Acoustic Modems                     Orca Instrumentation

     Container Inspection Systems Division

     The Container Inspection Systems Division competes with a number of
domestic and international competitors. At least two of these companies are
larger than the Company and offer a broader range of products. All of these
competitors offer some products

                                       10
<PAGE>

that compete with certain models offered by the Company. One German competitor
competes with the Company in the bottled beer leak detection market with
products substantially similar to those produced by the Company.

5.   Sources and Availability of Raw Materials

     The products of both divisions generally utilize mechanical and electrical
components that are readily available from a wide variety of domestic and
foreign vendors. In certain cases, the Company produces components internally,
utilizing its labor force and machine shop capability. Some components are
specially designed for specific products and are purchased from a single vendor.
A ceramic component that is used in the geophysical hydrophone product is
purchased from a single vendor, CTS Wireless Components, Inc., although the
Company believes that there are other vendors that possess the capability to
provide a replacement component. The Company's glass flotation products are also
purchased from a single vendor, Holophane Corp., although similar products could
be obtained from other vendors. The Company has not experienced any problems
with the supply of its raw materials and it believes that its sources of supply
are adequate for its present and future requirements.

6.   Dependence on Major Customers

     Although the Company has a number of major customers, during fiscal 1999,
only two customers, Syntron, Inc. and Schlumberger, Ltd., represented more than
10% of the Company's total revenue.

7.   Patents, Trademarks and Other Agreements

     The Company possesses several patents pertaining to the design and
manufacture of its products. Several names utilized by the Company are also
trademarked. It is the Company's policy to seek patent protection on products
and designs that it considers important to its future. However, the Company
believes that quality and technical superiority, rather than patent protection,
are the most important criteria for its future success. The Company does not
license any of its patents or designs to others at this time. The Company is
currently a licensee under a non-exclusive license pertaining to the design of
its seismic hydrophone product from The Penn State Research Foundation. The
Company is also a licensee under an exclusive agreement with Syntron, Inc. for a
patent pertaining to the design of the Company's GeoPoint hydrophone product.

<PAGE>

8.   Government Approvals and Contracts

     There are no government approvals required for any of the products
currently manufactured by the Company. Certain products of the Undersea Systems
Division cannot be sold to certain countries under U.S. export controls. Also,
certain hydrophone products must conform to regulations that limit the ability
of the hydrophone to be utilized for military applications. The Company does not
anticipate that these export restrictions will be removed in the near future.

     During fiscal 1999, less than 5% of the sales of the Undersea Systems
Division were derived from military procurement contracts, primarily contracts
with the U.S. Navy.

9.   Effect of Government Regulations

     The Company is not aware of any government regulations or pending
legislation that would adversely affect the future sales of its products.

10.  Research and Development

     The Company maintains an internal staff of engineers and external

fiscal years ended September 30, 1997, 1998 and 1999, respectively. In addition,
the Company has an ongoing technical consulting agreement with William D.
McElroy, an expert in undersea acoustics.

11.  Environmental Protection Regulations

     The Company believes that its compliance with current federal, state, and
local environmental regulations will not have a material adverse effect on its
capital expenditures, earnings, or competitive position.

12.  Employees

     As of September 30, 1999, the Company employed 118 full-time individuals,
26 of whom were engaged in research and development, 59 in manufacturing and 33
in sales, marketing and administrative positions. Of the 118 full-time
employees, four are employed on a temporary basis. None of the Company's
employees is covered by a collective bargaining agreement. The Company believes
that it maintains good relations with its employees.

space in two single-story, industrial buildings on a 34 acre rural setting. The
Undersea Systems Division and the Container Inspection Systems Division are
housed in separate facilities, each with its own dedicated engineering,
manufacturing, testing and sales administration staff. All facilities have been
recently modernized and are in good condition.

     In connection with the Datasonics acquisition, the Company leased two
buildings in the Cataumet section of Bourne, Massachusetts, containing 20,000
square feet of space used for office, administration and manufacturing. These
leases expire August 19, 2000 and the Company is in the process of relocating
the Datasonics operations to its North Falmouth headquarters.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS

     Overview

     The Company was founded in 1962 to act as a manufacturer of oceanographic
products. Over the last 37 years, the Company has developed and acquired new
technology and products. Currently, the Company consists of two distinct
divisions: the Undersea Systems Division and the Container Inspection Systems
Division. The Container Inspection Systems Division was formed in 1971 using
aspects of acoustic technology (originally developed for oceanographic products)
and applied to the testing of cans, bottles and other containers for the purpose
of finding leaks and other package defects.

     On August 19, 1999, the Company acquired substantially all of the assets of
Datasonics, Inc., a manufacturer of underwater acoustic products, including side
scan sonar systems, acoustic relocation devices, high-speed underwater acoustic
modems and data telemetry systems. The sales and income from the acquired
business are included in the Company's results of operations for the last six
weeks of fiscal 1999.

Years Ended September 30, 1999 and 1998.

Sales. Total sales increased 22.9% to $17,248,000 for fiscal year 1999 as
compared to $14,038,000 for fiscal year 1998. Sales by the Undersea Systems
Division increased by 31.0% to $12,174,000 for fiscal year 1999 as compared to
$9,290,000 for fiscal year 1998. This increase resulted primarily from increased
sales of the Company's geophysical hydrophone (used for offshore oil
exploration) and remotely operated vehicle (ROV) product lines and was somewhat
offset by decreases in sales of the Company's imaging and flotation product
lines. In addition, 1999 includes approximately six weeks' sales of the
Datasonics product lines acquired on August 19, 1999. Sales by the Container
Inspection Systems Division increased by 6.9% to $5,074,000 for fiscal year 1999
as compared to $4,748,000 for fiscal year 1998. This increase was attributable
to new products and an increase in international shipments.

Gross Profit. Gross profit increased by 14.4% to $7,447,000 for fiscal year 1999
as compared to $6,509,000 for fiscal year 1998. As a percentage of sales, gross
profit was 43.2% for fiscal year 1999 as compared to 46.4% for fiscal year 1998.
The decrease in the gross profit percentage is a result of a shift in product
mix

                                       16
<PAGE>

towards Undersea Systems Division products which have lower margins than
Container Inspection Systems Division sales.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 0.3% to $4,385,000 for fiscal year 1999 as
compared to $4,374,000 for fiscal year 1998. The minor increase in these
expenses was a result of increases in overall Company expenses coinciding with
the increased sales volume and decreases in selling expenses related to expense
control and a reduction in commission expenses due to product mix. As a
percentage of sales, selling, general and administrative expenses decreased to
25.4% for fiscal year 1999 as compared to 31.2% for fiscal year 1998.

Research and Development Expenses. Research and development expenses increased
10.0% to $1,363,000 for fiscal year 1999 as compared to $1,239,000 for fiscal
year 1998. As a percentage of sales, research and development expenses were 7.9%
for fiscal year 1999 as compared to 8.8% for fiscal year 1998. Although the
total amount of research and development expenses increased in fiscal 1999,
consistent with the Company's current operational plans, the percentage of sales
represented by those expenses decreased as a result of increased sales volume.

In-Process Research and Development. On August 19, 1999, the Company acquired
substantially all of the assets and assumed certain liabilities of Datasonics,
Inc. The Company acquired Datasonics for approximately $6.7 million (including
acquisition costs) and recorded the acquisition under the purchase method of
accounting. As a result, a purchase price premium of $5.3 million was recorded
on the transaction. A significant portion of the purchase price was identified
in an independent appraisal, using proven valuation procedures and techniques,
as intangible assets. These intangible assets included approximately $750,000
for in-process research and development for projects that did not have future
alternative uses. This allocation represents the estimated fair market value
based on risk-adjusted cash flows related to the in-process research and
development projects. At the date of acquisition, the development of these
projects had not yet reached technological feasibility, and the in-process
research and development had no alternative future uses. Accordingly, these
costs were written off in the fiscal quarter ended September 30, 1999. The
remaining premium of $4.5 million was allocated to identifiable intangibles and
goodwill, and is being amortized to operations over 6 to 13 years, with an
average amortization period of approximately 8 1/2 years. The acquisition was
financed from borrowings under a $5.5 million note payable to a bank.

As of August 19, 1999, Datasonics' in-process research and development value was
comprised of six primary research and development programs that were expected to
reach completion during

                                       17
<PAGE>

periods ranging from October 1999 through August 2000. At the acquisition date,
Datasonics' research and development programs ranged in completion from
approximately 41% to 61%, and total continuing research and development
commitments to complete the projects were expected to be approximately $400,000.
On the acquisition date, certain projects within the Datasonics research and
development programs were expected, if successful, to begin to bear results in
fiscal year 2000. Expenditures to complete the Datasonics projects were expected
to be approximately $400,000 in fiscal year 2000. These estimates are subject to
change, given the uncertainties of the development process, and no assurance can
be given that deviations from these estimates will not occur. Additionally,
these projects will require maintenance expenditures when and if they reach a
state of technological and commercial feasibility. Management believes the
Company is positioned to complete each of the major research and development
programs. However, there is risk associated with the completion of the projects,
and there is no assurance that any project will meet with either technological
or commercial success. The substantial delay or outright failure of the
Datasonics research and development could adversely impact the Company's
financial condition. See Note 2 of Notes to the Company's Consolidated Financial
Statements.

The value assigned to purchased in-process research and development was
determined by estimating the costs to develop Datasonics' purchased in-process
research and development into commercially viable products, estimating the
resulting net cash flows from the projects and discounting the net cash flows to
their present value. The revenue estimates used to value the in-process research
and development were based on estimates of relevant market sizes and growth
factors, expected trends in technology and the nature and expected timing of new
product introductions by the Company and its competitors. Discounting the net
cash flows back to their present value was based on the weighted average cost of
capital ("WACC"). The business enterprise is comprised of various types of
assets, each possessing different degrees of investment risk contributing to a
company's overall cost of capital. Intangible assets are assessed higher risk
factors due to their lack of liquidity and poor versatility for redeployment
elsewhere in the business. A discount rate of 17 percent was used for in-process
research and development. This rate is higher than the WACC due to the inherent
uncertainties surrounding the successful development of the purchased in-process
technology. The estimates used by the Company in valuing in-process research and
development were based upon assumptions the Company believes to be reasonable
but which are inherently uncertain and unpredictable. The Company's assumptions
may be incomplete or inaccurate, and no assurance can be given that
unanticipated events and circumstances will not occur. Accordingly, actual
results may vary from the projected results. Any such variance may result in a
material adverse effect on the financial condition and results of operations of
the Company.

                                       18
<PAGE>

Interest Income. Interest income increased to $176,000 for fiscal year 1999 as
compared to $165,000 for fiscal year 1998. This increase resulted from higher
invested cash balances and was offset by lower available returns on the invested
cash balances.

Interest Expense. Interest expense was $49,000 for fiscal year 1999 as compared
to $41,000 for fiscal year 1998. The increase was a result of borrowing on the
$5.5 million term loan made in August 1999 in connection with the Datasonics
acquisition, as compared to the Company's elimination of short and long term
debt in 1998.

Provision for Income Taxes. The provision for income taxes decreased to $248,000
for fiscal year 1999 as compared to $305,000 for fiscal year 1998. The effective
tax rate used for fiscal year 1999 was 23.0% as compared to an effective tax
rate of 29.9% used in fiscal year 1998. The rate used in fiscal year 1999 is
lower than the statutory rate due to an increased benefit from the Company's
foreign sales corporation and other state tax credits as compared to the prior
year.

Years Ended September 30, 1998 and 1997

Sales. Total sales decreased 14.5% to $14,038,000 for fiscal year 1998 as
compared to $16,414,000 for fiscal year 1997. Sales by the Undersea Systems
Division decreased by 3.1% to $9,290,000 for fiscal year 1998 as compared to
$9,591,000 for fiscal year 1997. This decrease resulted primarily from decreased
sales of the Company's acoustic and glass flotation product lines and was
somewhat offset by increases in sales of the Company's imaging, hydrophone (used
for offshore oil exploration), and remotely operated vehicle (ROV) product
lines. Sales by the Container Inspection Systems Division decreased by 30.4% to
$4,748,000 for fiscal year 1998 as compared to $6,823,000 for fiscal year 1997.
This decrease was attributable to fewer large project orders and the effects of
the Asian financial crisis, which caused some Asian customers to delay orders.

Gross Profit. Gross profit decreased by 25.8% to $6,509,000 for fiscal year 1998
as compared to $8,775,000 for fiscal year 1997. As a percentage of sales, gross
profit was 46.4% for fiscal year 1998 as compared to 53.5% for fiscal year 1997,
as a result of decreased sales of the Company's Container Inspection Systems
Division (which has higher profit margins) and start-up expenses incurred in
fiscal year 1998 related to the Company's Undersea Systems Division's new
Geopoint acoustic hydrophone product line.

Selling, General and Administrative Expenses. Selling, general and
administrative expenses decreased 10.8% to $4,374,000 for fiscal year 1998 as
compared to $4,903,000 for fiscal year 1997. The decrease in these expenses was
a result of lower commission and selling expenses relating to the decreased
sales volume, reductions

                                       19
<PAGE>

in overall Company expenses coinciding with this reduced sales volume and a
nonrecurrence of the expenses related to the registration and listing of the
Company's securities which occurred in fiscal year 1997. As a percentage of
sales, selling, general and administrative expenses increased to 31.2% for
fiscal year 1998 as compared to 29.9% for fiscal year 1997.

Research and Development Expenses. Research and development expenses decreased
5.2% to $1,239,000 for fiscal year 1998 as compared to $1,307,000 for fiscal
year 1997. As a percentage of sales, research and development expenses were 8.8%
for fiscal year 1998 as compared to 8.0% for fiscal year 1997. The increase in
percentage of sales is a result of investments in new product development and
reduced sales volume and is consistent with the Company's current operational
plans.

Interest Income. Interest income increased to $165,000 for fiscal year 1998 as
compared to $42,000 for fiscal year 1997. This increase resulted from higher
invested cash balances.

Interest Expense. Interest expense decreased 50% to $41,000 for fiscal year 1998
as compared to $82,000 for fiscal year 1997. The decrease was a result of no
borrowing on the credit line in fiscal year 1998 and the elimination of the
Company's short and long term debt in 1998.

Provision for Income Taxes. The provision for income taxes decreased to $305,000
for fiscal year 1998 as compared to $967,000 for fiscal year 1997. The effective
tax rate used for fiscal year 1998 was 29.9% as compared to an effective tax
rate of 38.3% used in fiscal year 1997. The rate used in fiscal year 1998 is
lower than the statutory rate due to the benefit from the Company's foreign
sales corporation and other state tax credits which benefitted the Company in
fiscal year 1998.

Liquidity and Capital Resources

     The Company's principal capital requirement is to provide working capital
to support growth.

     As of September 30, 1999 the Company had cash and cash equivalents of
$2,930,000 compared to a balance of $2,509,000 on September 30, 1998. Operating
income for the fiscal year ended September 30, 1999 was $949,000 as compared to
$896,000 for the fiscal year ended September 30, 1998. Accounts receivable
decreased by $355,000 as a result of improved collections. Inventories increased
by $919,000 to support early fiscal year 2000 shipments. Deferred tax assets
increased by $648,000 as the result of an increase in refundable income taxes.
Accounts payable increased by $226,000 as purchasing activities increased to
support necessary inventory levels. Accrued expenses increased by $405,000 as a
result of higher profit sharing expenses and current income taxes payable. Net
cash provided by operating activities increased to $1,588,000 for fiscal year
1999 as compared to $1,095,000 for fiscal year 1998.

                                       20
<PAGE>

     In the fiscal year ended September 30, 1999, the Company used $6,689,000
for investing activities. Of this total, $181,000 was used to purchase property,
plant, and equipment and $6,729,000 represents cash paid in connection with the
Datasonics acquisition.

     Cash provided by financing activities for the fiscal year ended September
30, 1999 was $5,522,000. Included in this were borrowings on long-term debt of
$5,500,000 used to finance the Datasonics acquisition, $45,000 from the exercise
of stock options, and $42,000 from the sale of treasury stock to the ESOP.

     The Company has a secured line of credit for $2,000,000. As of September
30, 1999, the Company had no outstanding advances against the line of credit.

     The Company believes that existing cash balances, current line of credit
arrangement and cash anticipated to be generated from operations will be
sufficient to finance the Company's operations for the next twelve months. A
portion of the Company's cash may be used to acquire or invest in complementary
businesses or products or to obtain the right to use complementary technologies.
From time to time, in the ordinary course of business, the Company evaluates
potential acquisitions of such businesses, products or technologies. The Company
engages in discussions and negotiations with respect to potential acquisitions
from time to time but has no current agreements or commitments at the present
time.

New Accounting Standards

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities, which
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives) and for hedging activities. SFAS No.
133, as amended by SFAS No. 137, is effective for all fiscal quarters of fiscal
years beginning after June 15, 2000. As the Company does not currently engage in
derivatives or hedging transactions, there will be no current impact to the
Company's results of operations, financial position or cash flows upon the
adoption of SFAS No. 133.

Prospects for the Future

     The Company will continue to focus resources on growth opportunities in the
markets that it serves. These activities will include research and development,
distribution channel development, and geographical market development. In
addition, the Company will continue its efforts at identifying and pursuing
strategically compatible product and/or company acquisitions.

Undersea Systems Division

     The Undersea Systems Division has made significant progress in penetrating
the market for geophysical oil and gas exploration. It is expected that this
division will continue to focus its resources on further business development in
this market. The Company believes that a number of its present products, as well
as those under development, are well-positioned to take advantage of developing
trends in the offshore oil and gas markets. These trends include an increased
effort to search for oil and gas deposits in deeper waters as well as efforts to
perform more accurate geophysical surveys in areas that were previously surveyed
using older, less accurate technology.

     The Company will also continue to maintain its presence and focus on its
traditional markets, including military, oceanographic research and nuclear
inspection. Some of these markets are affected by the level of U.S. Government
expenditures which have declined sharply in recent years. However, the Company
believes that some future recovery is likely and that several promising
opportunities presently exist within these markets.

     The Company also believes that the underwater data telemetry market is an
emerging market that will continue to develop during the next several years and
the Company intends to devote some of its resources towards capitalizing on this
developing market.

     The Company is not aware of any trends or changes in market characteristics
for the markets served by its Undersea Systems Division that would adversely
affect either sales or gross profits.

Container Inspection Systems Division

     The Container Inspection Systems Division serves the brewing, beverage,
food processing and pharmaceutical markets. An active competitive environment,
concerns about product liability, an increased focus on improving quality, and
efforts at cost reduction are characteristic trends within these industries.
These trends are favorable for the Company's products and the Company expects
these trends to continue in the future.

     The Company plans to maintain its focus on the domestic and international
beer market by improving its traditional leak detection equipment and by
developing other products that provide increased inspection capability to
brewers. The Company also plans to continue to develop its presence in the food
packaging market through enhanced marketing efforts coupled with product
development initiatives.

     The Container Inspection Systems Division competes with a number of
domestic and international companies. It is possible that increased competitive
pressures will be experienced in the

                                       22

future, affecting both sales and gross profits. The Company is not aware of any
technological trends that would adversely affect the sales of its products
within the industry segments served by its Container Inspection Systems
Division.

Profit Margins

Overall

     Overall profit margins on the Company's products are influenced by the
relative mix of sales between the Undersea Systems Division and the Container
Inspection Systems Division. For the fiscal year ended September 30, 1999, sales
of the Undersea Systems Division increased to 71% of total Company sales as
compared to 66% for the prior fiscal year, while sales of the Container
Inspection Systems Division decreased to 29% of total Company sales as compared
to 34% for the prior fiscal year. The increase in sales from fiscal year 1998 to
fiscal year 1999 was 31% for the Undersea Systems Division and 7% for the
Container Inspection Systems Division. This resulted in an overall gross profit
for the Company of 43.2% for the fiscal year ended September 30, 1999 as
compared to 46.4% for the fiscal year ended September 30, 1998.

Undersea Systems Division

     Gross profit margins on Undersea Systems Division products average
approximately 47.4%. The Company expects that the overall sales mix of its
undersea products will shift slightly in the future due to decreased sales of
hydrophone products to the offshore oil and gas market. The Company does not
expect this sales mix to adversely affect overall profit margins. It is possible
that increased competition will result in lower realized selling prices for
certain products, especially hydrophones, resulting in reductions in product
profit margins. The Company is not aware of other trends or competitive
pressures that would adversely affect either product mix or gross profit margins
within other product lines.

Container Inspection Systems Division

     Gross profit margins on Container Inspection Systems Division products
average approximately 54.5%. The Company expects that the sales mix of different
products will not significantly change and will not adversely affect overall
divisional gross margins in the future. It is possible that increased
competition will result in an overall reduction of selling prices and associated
profit margins. The Company is not aware of any technological trends or
marketplace trends which would adversely affect gross margins on these product
lines.

Forward-Looking Information

     The statements made in this report and in oral statements which may be made
by representatives of the Company relating to plans, strategies, economic
performance and trends and other statements that are not descriptions of
historical facts may be forward-looking statements within the meaning of the
Private Securities Litigation Reform Act, Section 27A of the Securities Act of
1933 and Section 21E of the Securities Exchange Act of 1934. Such information
includes information relating to the Company which is based upon the beliefs of
the Company's management as well as assumptions made by and information
currently available to the Company's management. When used in this report, words
such as "anticipate," "believe," "estimate," "expect," "intend," and similar
expressions, as they relate to the Company's management, identify forward-
looking statements. Such statements reflect the current views of management with
respect to future events and are subject to certain inherent risks,
uncertainties and assumptions relating to the operations and results of
operations of the Company, the timing of large project orders, competitive
factors, shifts in customer demand, government spending, economic cycles,
availability of financing as well as the factors described in this report.
Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual results or outcomes may vary
materially from those described herein as anticipated, believed, estimated,
expected or intended.

Year 2000 Issues

     During 1998 and 1999, the Company was actively engaged in addressing Year
2000 ("Y2K") issues, which result from the use of two-digit, rather than four-
digit, year dates in software, a practice which could cause date-sensitive
systems to malfunction or fail because they may not recognize or process date
information correctly.

State of Readiness: To manage its Y2K program, the Company has divided its
efforts into four program areas:

     .    Information Technology (computer hardware and software)

     .    Physical Plant (manufacturing equipment and facilities)

     .    Products (including product development)

     .    Extended Enterprise (suppliers and customers)

     For each of these program areas, the Company has used a four-step approach:

                                       24
<PAGE>

     .    Ownership (creating awareness, assigning tasks)

     .    Inventory (listing items to be assessed for Y2K readiness)

     .    Assessment (prioritizing the inventoried items, assessing their Y2K
          readiness, planning corrective actions, developing initial
          contingency plans)

     .    Corrective Action Deployment (implementing corrective actions,
          verifying implementation, finalizing and executing contingency plans)

     As of September 30, 1999, the Ownership, Inventory, Assessment and
Corrective Action Development steps were essentially complete for all program
areas.

     Costs to Address Y2K Issues: The Company began incurring expenses in 1997
to resolve this issue. All expenditures have been expensed as incurred and have
not had (and are not expected to have) a significant impact on the Company's
ongoing results of operations.

     Risks of Y2K Issues and Contingency Plans: The Company has been in the
process of assessing the Year 2000 issues relating to its physical plant,
products and suppliers. The Company has developed a contingency planning process
to mitigate worst-case business disruptions such as delays in product delivery,
which could potentially result from events such as supply chain disruptions. The
Company expects its contingency plans to be complete by December 31, 1999.

                   Report of Independent Public Accountants



To Benthos, Inc.:

We have audited the accompanying consolidated balance sheets of Benthos, Inc. (a
Massachusetts corporation) and subsidiary as of September 30, 1999 and 1998, and
the related consolidated statements of income, stockholders' investment and cash
flows for each of the three years in the period ended September 30, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Benthos, Inc. and subsidiary as
of September 30, 1999 and 1998, and the results of their operations and their
cash flows for each of the three years in the period ended September 30, 1999,
in conformity with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements

                (In Thousands, except share and per share data)



(1)  Operations and Significant Accounting Policies

     Benthos, Inc. (the Company) designs, manufactures, sells and services
     oceanographic products and systems for underwater exploration, oil and gas
     development and production, research and defense, as well as electronic
     inspection equipment for the automated assessment of the seal integrity of
     consumer food, beverage, pharmaceutical and chemical containers.  The
     Company's customers are located throughout the world.

     The accompanying consolidated financial statements reflect the application
     of certain significant accounting policies as described below and elsewhere
     in the accompanying notes to the consolidated financial statements.

     (a)  Principles of Consolidation

          The consolidated financial statements include the accounts of the
          Company and its wholly owned subsidiary, Benthos International Inc., a
          foreign sales corporation. All material intercompany transactions and
          balances have been eliminated in consolidation.

     (b)  Management 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 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.

     (c)  Cash and Cash Equivalents

          The Company considers all highly liquid securities with original
          maturities of three months or less to be cash equivalents.

     (d)  Inventories

          Inventories are stated at the lower of cost (first-in, first-out) or
          market. Work-in-process and finished goods inventories include
          materials, labor and overhead. Inventories consist of the following at
          September 30, 1999 and 1998:

     (e)  Depreciation and Amortization

          The Company provides for depreciation and amortization using the
          straight-line method by charges to operations in amounts estimated to
          allocate the cost of the assets over their estimated useful lives, as
          follows:

                                                Estimated
                    Asset Classification       Useful Life

                Buildings and improvements       15-33 years
                Equipment and fixtures               5 years
                Demonstration equipment              3 years

     (f)  Intangible Assets

          The Company assesses the realizability of intangible assets in
          accordance with Statement of Financial Accounting Standards (SFAS) No.
          121, Accounting for the Impairment of Long-Lived Assets and for Long-
          Lived Assets to Be Disposed Of. Under SFAS No. 121, the Company is
          required to assess the valuation of its long-lived assets, including
          intangible assets, based on the estimated cash flows to be generated
          by such assets. Based on its most recent analysis, the Company
          believes that no material impairment of intangible assets exists as of
          September 30, 1999.

          Intangible assets, resulting from Datasonics Acquisition (Note 2), are
          included in "Other Assets" on the face of the consolidated balance
          sheets and are amortized on a straight-line basis, based on their
          estimated lives, as follows:

                                  (Continued)

     (g) Revenue Recognition and Warranty Costs

         The Company recognizes revenue upon shipment and provides for estimated
         warranty costs at that time. Amounts received from customers for future
         delivery are shown as customer deposits in the accompanying
         consolidated balance sheets.

     (h) Concentration of Credit Risk

         SFAS No. 105, Disclosure of Information about Financial Instruments
         with Off-Balance-Sheet Risk and Financial Instruments with
         Concentration of Credit Risk, requires disclosure of any significant
         off-balance-sheet and credit risk concentrations. The Company has no
         significant off-balance-sheet concentration of credit risk such as
         foreign exchange contracts, options contracts or other foreign hedging
         arrangements. Financial instruments, which potentially subject the
         Company to concentrations of credit risk, are principally cash, cash
         equivalents and accounts receivable. The Company places its cash and
         cash equivalents in rated financial institutions. In 1999, two
         customers accounted for 14% and 12% of net sales, respectively. In 1998
         and 1997, one customer accounted for approximately 22% and 16% of net
         sales, respectively. As of September 30, 1999, one customer accounted
         for 15% of accounts receivable. At September 30, 1998, one customer
         accounted for approximately 30% of accounts receivable. The Company has
         not experienced significant losses related to receivables from
         individual customers or groups of customers in any specific industry or
         geographic area. Due to these factors, no additional credit risk beyond
         amounts provided for collection losses is believed by management to be
         probable in the Company's accounts receivable.

         The changes in the accounts receivable reserve are as follows:

                                  (Continued)

     (i)  Reclassifications

          The Company has reclassified certain prior year information to conform
          with the current year's presentation.

     (j)  Financial Instruments

          The estimated fair value of the Company's financial instruments, which
          include cash and cash equivalents, accounts receivable and debt,
          approximate their carrying value.

     (k)  New Accounting Standards

          In June 1998, the Financial Accounting Standards Board (FASB) issued
          SFAS No. 133, Accounting for Derivative Instruments and Hedging
          Activities, which establishes accounting and reporting standards for
          derivative instruments, including certain derivative instruments
          embedded in other contracts (collectively referred to as derivatives)
          and for hedging activities. SFAS No. 133, as amended by SFAS No. 137,
          is effective for all fiscal quarters of fiscal years beginning after
          June 15, 2000. As the Company does not currently engage in derivatives
          or hedging transactions, there will be no current impact to the
          Company's results of operations, financial position or cash flows upon
          the adoption of SFAS No.133.

     (l)  Comprehensive Income

          The Company has adopted SFAS No. 130, Reporting Comprehensive Income.
          SFAS No. 130 requires disclosure of all components of comprehensive
          income on an annual and interim basis. Comprehensive income is defined
          as the change in equity of a business enterprise during a period from
          transactions and other events and circumstances from nonowner sources.
          Comprehensive income is the same as net income for all periods
          presented.

     (2)  Acquisition of Datasonics, Inc.

          In August 1999, the Company acquired substantially all of the assets
          of Datasonics, Inc. (Datasonics). This acquisition was accounted for
          as a purchase in accordance with Accounting Principles Board (APB)
          Opinion No. 16, Business Combinations. To fund the purchase, the
          Company entered into a $5.5 million note payable with a bank (see Note
          5). The aggregate purchase price of approximately $6,732 (which
          consisted of a $6,011 of cash and $721 of direct acquisition costs)
          was allocated based on the fair value of the tangible and intangible
          assets acquired as follows:

   In connection with the purchase price allocation, the Company obtained an
   independent appraisal of the intangible assets acquired.  Acquired
   intangibles include acquired technology, goodwill and an assembled workforce.
   These intangibles are being amortized over their estimated useful lives of
   six to 13 years.  The portion of the purchase price allocated to the
   purchased incomplete research and development projects that had not yet
   reached technological feasibility and did not have a future alternative use,
   totaling $750, was charged to expense as of the acquisition date.  The amount
   allocated to the purchased incomplete research and development projects
   represents the estimated fair value related to these projects determined by
   an independent appraisal.  Proven valuation procedures and techniques were
   used in determining the fair market value of each intangible asset.  To bring
   these projects to technological feasibility, high-risk developmental and
   testing issues needed to be resolved, which required substantial additional
   effort and testing.

     differences, about which the Company believes there is uncertainty
     regarding realizability.

          period, commencing one year from the date of grant, and expire not
          more than 10 years from the date of grant. The purchase price

       In October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
       Compensation.  SFAS No. 123 requires the measurement of the fair value of
       stock options or warrants to be included in the statement of operations
       or disclosed in the notes to financial statements.  The Company has
       determined that it will continue to account for stock-based compensation
       for employees under APB Opinion No. 25 and elect the disclosure-only
       alternative under SFAS No. 123 for stock-based compensation awarded in
       1999, 1998 and 1997 using the Black-Scholes option pricing model
       prescribed by SFAS No. 123.  The underlying assumptions used are as
       follows:

   (b) Employee Stock Ownership Plan

       The Company has an Employee Stock Ownership Plan (ESOP) for substantially
       all employees.  Contributions to the ESOP are made at the discretion of
       the Board, provided that the total amount contributed for any ESOP year
       does not exceed the maximum amount allowable by the Internal Revenue
       Code.  Amounts allocated to a participant's account vest ratably over
       five years based on years of completed service, as defined.  The
       accompanying consolidated statements of income for the years ended
       September 30, 1999, 1998 and 1997 include provisions for contributions to
       the ESOP of approximately $74, $41, and $71, respectively.

   (c) 401(k) Retirement Plan

       The Company maintains a 401(k) retirement plan covering all eligible
       employees, as defined.  Contributions to the plan are made at the
       discretion of the Board in an amount determined by the Board.  These
       contributions vest to a participant's account ratably over five years
       based on years of completed service, as defined.  Additionally, each
       participant may elect to contribute up to 20% of his or her compensation
       for the plan year, but not more than $10,000 (for calendar 1999), to the
       plan.  The accompanying consolidated statements of income for the years
       ended September 30, 1999, 1998 and 1997 include provisions for
       contributions to the plan of approximately $74, $41, and $210,
       respectively.

   (d) Supplemental Executive Retirement Plan

       The Company has a Supplemental Executive Retirement Plan (SERP) for the
       benefit of certain management and highly compensated executive employees.
       Under the SERP, participants may elect to defer a portion of their
       compensation paid by the Company for supplemental retirement benefits.
       The Company also established the Supplemental Executive Retirement Trust
       (the Trust Fund) and shall regularly transfer to the Trust Fund amounts
       equal to the elective deferrals made by participants under the SERP.  No
       such elective deferrals have been made by participants as of September
       30, 1999.

(9)  Earnings per Share

     Basic earnings per share were computed by dividing net income by the
     weighted average number of common shares outstanding during the period.
     Diluted earnings per share were computed by dividing net income by diluted
     weighted average number of common and common equivalent shares outstanding
     during the period. The weighted average number of common equivalent shares
     outstanding has been determined in accordance with the treasury-stock
     method. Common stock equivalents consist of common stock issuable upon the
     exercise of outstanding options.

     As of September 30, 1999 and 1998, 106,719 and 91,500 options,
     respectively, were outstanding but not included in the diluted weighted
     average common share calculation as the effect would have been
     antidilutive. As of September 30, 1997, there were no antidilutive shares.

(10) Employment and Noncompetition Agreement

     The Company has an employment and noncompetition agreement, as amended,
     with a director/stockholder. In connection with the employment agreement,
     the Company has agreed to provide a $1,500 split-dollar life insurance
     policy on the director/stockholder. At the director/stockholder's request,
     the Company may be obligated to repurchase from the director/stockholder
     the number of shares that are contributed to or purchased by the Company's
     ESOP each year. The Company also has the right of first refusal on any
     future sales of common stock by the director/stockholder at fair market
     value. In addition, a change in the control of the Company, as defined,
     will result in certain payments to the director/stockholder, as outlined
     under the employment agreement.

     Compensation expense of approximately $86, $85, and $93 related to this
     agreement is included in the accompanying 1999, 1998 and 1997 consolidated
     statements of income, respectively.

(11) Segment Reporting

     The Company has adopted SFAS No. 131, Disclosures about Segments of an
     Enterprise and Related Information, in the fiscal year ended September 30,
     1999. SFAS No. 131 establishes standards for reporting information
     regarding operating segments in annual financial statements and requires
     selected information of those segments to be presented in interim financial
     reports issued to stockholders. SFAS No. 131 also establishes standards for
     related disclosures about products and services and geographic areas.
     Operating segments are identified as components of an enterprise about
     which separate discrete financial information is available for evaluation
     by the chief operating decision maker, or decision making group, in making
     decisions on how to allocate resources and assess performance. The
     Company's chief decision-maker, as defined under SFAS No. 131, is a
     combination of the president, the chief financial officer and other
     operating officers. To date, the Company has viewed its operations and

            as Amended and Restated Effective as of October 1, 1987


          AMENDMENT adopted this 22/nd/ day of October 1997, by Benthos, Inc.
(hereinafter referred to as the "Company"):


                                  WITNESSETH:
                                  ----------

          WHEREAS, the Company has heretofore adopted a defined contribution
plan known as the "Benthos, Inc. Employee Stock Ownership Plan", which was
amended and restated effective as of July 1, 1987 (the "Plan") and

          WHEREAS the Company previously amended said amended and restated Plan
to make a technical modification to the provisions pertaining to the limit on
"annual additions;" and

          WHEREAS, the Company, pursuant to Section 16.1 of the Plan, has
reserved the right to amend the Plan at any time by vote of its Board of
Directors; and

          WHEREAS, the Company wishes to amend further the Plan to permit
distributions to Participants or their Beneficiaries as soon as practicable
following retirement, death or other termination of employment.

          NOW, THEREFORE, effective as of October 1, 1996, unless otherwise
specified, the Plan is hereby amended as follows:

          1. Section 8.1(a) is amended to read as follows:

                    (a) Upon a Participant's attaining his Normal Retirement
               Age, or upon his becoming a Disabled Participant, he shall become
               entitled to the total value of his Account. The amount to which
               the Participant is entitled shall be paid as provided in this
               Article VIII in the form specified in Section 8.2 as soon as
               practicable following his Normal Retirement Date, or if later,
               his actual retirement date, but in no event shall commence later
               than the earlier of (i) 60 days after the end of the Plan Year in
               which he retires, unless the Participant elects to defer the
               payment of his benefit pursuant to subsection (b) or (ii) his
               Required Distribution Date. Any additional amounts to which a
               retired or Disabled Participant who has received a distribution
               shall become entitled (for example, as a result of an additional
               Company contribution or allocation or forfeiture) shall be paid
               to him as soon as practicable following the end of the Plan Year
               in which such distribution was made.

                                      -1-
<PAGE>

     2. The reference in Section 9.3(a) to "Section 12.7" is hereby changed to
     "Section 12.5."

     3. The first sentence of Section 9.3(c) is amended to read as follows:

                 The amount to which the Beneficiary is entitled shall be
            available for distribution to the Beneficiary as soon as practicable
            following the death of the Participant.

     4. Section 10.2(a) is deleted in its entirety and the following
     substituted therefor:

                 (a)  If the vested value of the Account of an Inactive
            Participant whose employment terminated before attaining Normal
            Retirement Age does not exceed $3,500 ($5,000 for Plan Years
            beginning on or after October 1, 1997), the Administrative Committee
            shall direct the Trustee to distribute the vested value to such
            Participant in a lump sum in whole Shares with fractional Shares
            paid in cash without the consent of the Participant. Subject to the
            requirements of Section 12.5, this distribution shall be made as
            soon as practicable following the termination of the Inactive
            Participant's employment. If the vested value of the Account of an
            Inactive Participant whose employment terminated before attaining
            his Normal Retirement Age exceeds $3,500 ($5,000 for Plan Years
            beginning on or after October 1, 1997) the individual may elect to
            have the vested value paid to him or applied for his benefit in
            accordance with the provisions of Article VIII as soon as
            practicable following his termination of employment or at any time
            thereafter. The vested value of an Inactive Participant's Account
            shall be determined as of the Valuation Date immediately preceding
            or coinciding with his Benefit Starting Date.

     In all other respects of the terms of the Plan remain unchanged and in full
force and effect.

     IN WITNESS WHEREOF, the undersigned Company has caused this Amendment to be
executed by its duly authorized officer as of the day and year set forth above.

                              THIRD AMENDMENT TO
                  BENTHOS, INC. EMPLOYEE STOCK OWNERSHIP PLAN
            as Amended and Restated Effective as of October 1, 1987

     This AMENDMENT is adopted this 16th day of July 1999, by Benthos, Inc.
(hereinafter referred to as the "Company"):

                                  WITNESSETH:
                                  ----------

     WHEREAS, the Company has heretofore adopted a defined contribution plan
known as the "Benthos, Inc. Employee Stock Ownership Plan", which was amended
and restated effective as of October 1, 1987 and was further amended effective
October 1, 1996 (the "Plan"); and

     WHEREAS, the Company, pursuant to Section 16.1 of the Plan, has reserved
the right to amend the Plan at any time by vote of its Board of Directors; and

     WHEREAS, the Company wishes to amend further the Plan to change the first
paragraph of the definition of "Compensation".

     NOW, THEREFORE, effective as of October 1, 1998 the Plan is hereby amended
as follows:

     The definition of "Compensation" set forth in ARTICLE II is amended by
deleting the first paragraph thereof and substituting the following therefor:

     "Compensation" means all of an Employee's "wages" within the meaning of
Section 3401(a) of the Code in connection with income tax withholding at the
source, and all other compensation paid to the Employee by the Company in the
course of its trade or business, for which the Company is required to furnish
the Employee with a written statement under Sections 6041(d), 6051(a)(3) and
6052 of the Code, determined without regard to exclusions based on the nature or
location of the employment or the services performed (such as the exception for
agricultural labor in Section 3401(a)(2) of the Code). Compensation shall
include only amounts actually paid to the Employee during the Plan Year, except
that (1) Compensation shall exclude bonuses, commissions, and compensation for
services of a type customarily performed by outside contractors (but shall
include overtime pay); and (2) in an Employee's initial year of participation in
the Plan, Compensation shall include only amounts actually paid to the Employee
from the Employee's effective date of participation pursuant to Section 3.1 to
the end of the Plan Year, or, if earlier, to the date on which the Employee
ceases to be a Participant. In addition, Compensation shall include any amount
which is contributed to an employee benefit plan for the Employee by the Company
pursuant to a salary reduction agreement, and which is not otherwise includible
in the gross income of the Employee under Section 125, 402(e)(3), 402(h)(B),
SARSEP or 403(b) of the Code.

<PAGE>

     In all other respects the terms of the Plan remain unchanged and in full
force and effect.

     IN WITNESS WHEREOF, the Company has caused this Third Amendment to be
executed in the name of and on behalf of the Company by its duly authorized
officer as of the day and year set forth above.

                                REVOLVING LOANS

     Section 2.01. Revolving Loans. Subject to the terms and conditions
                   ---------------
hereinafter set forth, the Lender will make loans ("Revolving Loans") under this
Article II to the Borrower at the Principal Office of the Lender on any Business
Day prior to the first to occur of (i) the Expiration Date or (ii) the earlier
termination of the Revolving Commitment pursuant to the express terms of this
Agreement, in such amounts as the Borrower may request; provided, however, that
                                                        --------  -------
the aggregate outstanding balance due pursuant to the Revolving Loans shall at
no time exceed the Revolving Commitment Amount. Each Revolving Loan shall be a
Fully Variable Prime Rate Loan. The Borrower may obtain Revolving Loans, repay
Revolving Loans and obtain Revolving Loans again on one or more occasions. The
Revolving Loan shall mature as of the Expiration Date, but may be renewed by the
Lender, in its sole discretion, on a year-to-year basis thereafter subject to
satisfactory review of the Borrower's financial condition and compliance with
the Borrower's then current underwriting criteria.

make or cause to be made, on a schedule attached to the Revolving Note or on the
books of the Lender, at or following the time of the making of each Revolving
Loan and at the time of receiving any payment of principal thereon, an
appropriate notation reflecting such transaction and the then aggregate unpaid
principal balance of the Revolving Loans. The amount so noted shall constitute
presumptive evidence as to the amount owed by the Borrower with respect to the
principal amount of the Revolving Loans. Failure of the Lender to make any such
notation shall not, however, affect any obligation of the Borrower or any right
of the Lender hereunder or under the Revolving Note.

     Section 2.03. Requests for Revolving Loans. The Borrower shall give notice
                   ----------------------------
(a "Notice of Borrowing") to the Lender by 1:30 p.m. (Boston, Massachusetts
time) on the proposed date of funding such Revolving Loan. Each Notice of
Borrowing shall be given to the Lender in writing in substantially the form of
Exhibit      attached hereto, specifying (a) the requested date of funding such
- -------------
Revolving Loan (which shall be a Business Day) and (b) the amount of such
Revolving Loan. The Borrower agrees to indemnify and hold the Lender harmless
for any action or inaction, including the making of Revolving Loans hereunder,
or losses or expenses, taken or incurred by the Lender in good faith reliance
upon such Notice of Borrowing.

     Section 2.04. Interest Payments. (a) The Borrower will pay interest on the
                   -----------------
principal amount of each Revolving Loan outstanding from time to time, from the
date of the initial Revolving Loan until payment of all Revolving Loans in full,
such interest to be payable (i) monthly in arrears on the first day of each
month, commencing with the first day of the first month after the initial
Revolving

                                       7
<PAGE>

Loan and (ii) on the date of any voluntary or mandatory repayment of all or a
portion of any Revolving Loan. The rate of interest so payable shall be a
fluctuating rate per annum which shall at all times be equal to the sum of the
Prime Rate minus one quarter of one percent (0.25%), but, in no event, in excess
of the maximum rate then permitted by applicable law, with a change in such rate
of interest to become effective on the same day on which any change in the Prime
Rate is effective.

     (b)  Interest payable under the Revolving Loans shall be computed on the
basis of a year of 360 days for the number of days actually elapsed.

     (c)  Overdue principal and, to the extent permitted by law, interest shall
bear interest at a fluctuating rate per annum which at all times shall be equal
to the Prime Rate plus [four percent (4%)] (but in no event in excess of the
maximum rate permitted by then applicable law), payable on demand.

     Section 2.05. Mandatory Repayment. The Borrower shall repay in full the
                   -------------------
principal balance of all Revolving Loans and all interest thereon upon the first
to occur of: (i) the Expiration Date, or (ii) an acceleration under Subsection
11.02(a) following an Event of Default.

     Section 2.06. Voluntary Repayment. The Borrower may prepay, at any time,
                   -------------------
the whole or any portion of the principal balance of the Revolving Loans without
premium or penalty. Each such prepayment shall be accompanied by (i) the payment
of the full amount of interest accrued but unpaid to the date of such prepayment
for each Revolving Loan being prepaid in whole or in part, and (ii) if such
prepayment is less than the aggregate outstanding balance of all of the
Revolving Loans, the principal amount of such prepayment shall be Twenty Five
Thousand Dollars ($25,000) or an integral multiple thereof.

of which loan shall be used to fund the Acquisition. On or before the Closing
Date, the Borrower shall elect whether the Term Loan will be (a) a Fully
Variable Prime Rate Loan, (b) an Annually Adjusted Prime Rate Loan or (c) a
Fixed Rate Loan. If the Borrower elects to have the Term Loan be classified as
either a Fully Variable Prime Rate Loan or an Annually Adjusted Prime Rate Loan,
the Borrower may elect to convert the Term Loan to a Fixed Rate Loan at any
time, prior to the Term Loan Expiration Date or the occurrence of an Event of
Default.

     Section 3.02. Term Note. The Term Loan shall be evidenced by the Term Note

the first day of each month, commencing with the first day of the first month
after the date hereof, (ii) on the date of any voluntary or mandatory repayment
of all or a portion of the Term Loan. The Term Loan shall bear interest as set
forth in the Term Note.

             (b)    Interest payable on the Term Loan shall be computed on the
basis of a year of 360 days for the number of days actually elapsed.

             (c)    Overdue principal and, to the extent permitted by law,
interest owing on the Term Loan shall bear interest at a fluctuating rate per
annum which at all times shall be equal to the Prime Rate plus [four percent
(4%)] (but in no event in excess of the maximum rate permitted by then
applicable law), payable on demand.

     Section 3.04.  Amortization of Term Loan.
                    -------------------------

             (a)    The Borrower shall repay the Term Loan on the first date of
each month beginning on September 1, 1999 (or, if such date is not a Business
Day, on the immediately preceding Business Day) in eighty-four (84) monthly
payments, the first eighty-three of which payments shall be in the amount of
$65,475.19, plus such interest as is payable pursuant to Section 3.03(a) hereof,
and the eighty-fourth of which payment shall be due on the Term Loan Expiration
Date and shall be in the full amount of the principal then outstanding under the
Term Loan, plus such interest as is payable pursuant to Section 3.03(a) hereof.

     Section 3.05.  Prepayment of Term Loan. Except as hereinafter provided,
                    -----------------------
Borrower shall have the right to prepay Term Loan incurred by it in whole or in
part from time to time without premium or penalty in multiples of Twenty Five
Thousand Dollars ($25,000) only. The foregoing notwithstanding, to the extent
that the Term Loan is a Fixed Rate Loan, there will be a prepayment fee
associated with any prepayment, whether in whole or in part, if on the date of
such prepayment, the Federal Home Loan Rate for the period of time nearest to
the remaining period of maturity of the Loan (the "Comparison Rate") is less
than the Federal Home Loan Rate at the time of conversion to a Fixed Rate Loan
(the "Base Rate"), the prepayment will be the difference between the Base Rate
and the Comparison Rate times the prepayment amount, times the remaining period
to the maturity of the Term Loan.

with the amount of all payments of interest, principal and other sums due, from
time to time, under this Agreement and/or the Notes; and will thereafter notify

                   ----------------
regulation, policy, guideline or directive (whether or not having the force of
law), or any interpretation thereof, or the compliance by the Lender with any of
the foregoing,

          (a)  subjects the Lender to any tax, duty, charge or withholding on or
     from payments due from the Borrower (excluding taxation of the overall net
     income of the Lender), or changes the basis of taxation of payments to the
     Lender in respect of the Revolving Loans; or

          (b)  imposes, or increases, or deems applicable any reserve,
     assessment, insurance charge, special deposit or similar requirement
     against assets of, deposits with, or credit extended by, the Lender; or

          (c)  imposes any other condition, the result of which is to increase
     the cost to the Lender of making, funding or maintaining the Loans, or
     reduces any amount receivable by the Lender in connection with the Loans,
     or requires the Lender to make any payment calculated by reference to the
     amount of the Loans held or interest received on the Loans; or

          (d)  affects the amount of capital required or expected to be
     maintained by the Lender or any corporation controlling the Lender, and the
     Lender determines the amount of capital required is increased by, or based
     upon, the existence of this Credit Agreement or its obligation to make the
     Loans hereunder or of commitments of this type;

                                       11

then, upon notice to the Borrower in accordance with Section 14.03 hereof, the
Borrower shall pay to the Lender that portion of such increased expense incurred
(including, in the case of the preceding clause (d), any reduction in the rate
of return on capital to an amount below that which the Lender could have
achieved but for such change in regulation, after taking into account the
Lender's policies as to capital adequacy), or reduction in an amount received,
which the Lender determines is attributable to making, funding and maintaining
the Revolving Loans.

     Section 5.02  Notice to Borrower  If the Lender shall determine that it is
                   ------------------
entitled to reimbursement pursuant to Section 5.01 hereof, the Lender shall give
notice thereof to the Borrower, whereupon the Borrower shall pay such amount to
the Lender within thirty (30) days of receipt of such notice. Such notice shall
set forth the nature of the occurrence giving rise to such compensation, the
additional amount or amounts to be paid to the Lender, and the method by which
such amounts were determined. Such notice shall be conclusive evidence of the
amount owed by the Borrower in the absence of manifest error. In determining
such amount, the Lender may use any reasonable averaging and attribution
methods. No failure on the part of the Lender to demand compensation on any one
occasion shall constitute a waiver of its right to demand such compensation on
any other occasion.

     (c)  The execution, delivery and performance of this Agreement, the Notes,
the Security Instruments and the other documents required to be executed by the
Borrower pursuant hereto have been duly authorized by all necessary corporate
action, will not require the consent of any third party, and will not conflict

Event of Default on the part of the Borrower under any contract, agreement, law,
rule, order, ordinance, franchise, instrument or other document or under any
provision of the Charter or By-laws of the Borrower, or will result in the
imposition of any lien or encumbrance on any property or assets of the Borrower,

and provisions hereof, the Borrower covenants and agrees that, so long as any
Loan is outstanding or any obligation of the Borrower to the Lender, in any

governmental charges or levies imposed upon it or them, or upon its or their
income or profits, or upon any properties belonging to it or them, prior to the

Borrower; provided, that the Borrower shall not be required to pay any such tax,

timely manner, all lease obligations, all trade debt, purchase money

insurance companies or associations satisfactory to the Lender in such amounts

becoming a co-insurer, and which shall in no event be less than the amount and
coverage in effect on the date of this Agreement and as reflected in the
certificates of insurance delivered by the Borrower to the Lender on the date
hereof. All insurance herein provided for shall be in such form and written by
such companies as may be satisfactory to the Lender. Regardless of the types or
amounts of insurance required and approved by the Lender, the Borrower shall
assign and deliver to the Lender duplicate original copies or certificates for
all policies of insurance, as collateral and further security for the

requested, to the Lender; and whenever any insurance is to expire for any
reason, the Borrower will deliver to the Lender, at least thirty (30) days prior
to such expiration, a renewal or replacement policy, complying with all of the
conditions of this Section, marked "premium paid" or accompanied by other
evidence of payment satisfactory to the Lender. Any sums received by the Lender
in payment of losses under such policies may, at the option of the Lender,
either (i) be applied to the payment or prepayment of any obligations of the
Borrower to the Lender, or (ii) be transmitted in whole or in part to the owner
of the property damaged or destroyed for the purpose of repairing or replacing
the same.

rules, regulations and the orders of any court or other tribunal or governmental

at any time following the occurrence of an Event of Default), permit the Lender,

as good condition and repair as same were on the date hereof, or in such better
condition and repair as same may have been put thereafter. The Borrower will not
waste or destroy or suffer the waste or destruction of the Collateral or the
Premises or any part thereof. The Borrower will not use any of the Collateral or
the Premises in violation of any insurance thereon. In the event of damage to or
destruction of all or any part of the Premises or the Collateral from any cause,
the Borrower shall repair, replace, restore and reconstruct the Premises (in the
case of leased Premises, to the extent required by the lease thereof) and the
Collateral to the extent necessary to restore each portion of same to
substantially its condition immediately prior to such damage or destruction, and
this obligation shall not be limited by the amount of insurance proceeds

                                                -------

                     ------------------------------
Event of Default and at any time thereafter, in addition to any other rights and
remedies available to the Lender hereunder or otherwise, the Lender may exercise
any one or more of the following rights and remedies (all of which shall be
cumulative):

     (a) Declare the entire unpaid principal amount of the Notes then
outstanding, all interest accrued and unpaid thereon and all other amounts
payable under this Agreement, and all other Indebtedness of the Borrower to the
Lender, to be forthwith due and payable, whereupon the same shall become
forthwith due and payable, without presentment, demand, protest or notice of any
kind, all of which are hereby expressly waived by the Borrower.

     (b) Terminate the Revolving Commitment hereunder.

                                       29
<PAGE>

     (c)  Exercise all of the rights and remedies of a secured party under the
Uniform Commercial Code. The Lender may enter upon the Premises and may take
physical possession of the Collateral or render the Collateral unusable by
process of law or peaceably without process of law. The Borrower shall
peacefully and quietly yield up and surrender its Collateral and shall upon the
request from the Lender assemble it and make it available to the Lender at a
place or places designated by the Lender which is or are reasonably convenient
to the Borrower and the Lender. The Lender may maintain possession of any
Collateral on any property owned, leased by or licensed to the Borrower or
remove same or any part thereof to such place or places as the Lender may elect.
The Borrower will also deliver to the Lender upon request all documents of title
and other instruments relating to the Collateral. The Borrower waives all rights
which it would otherwise have had under law to prohibit entry to any Premises or
to require notice of any replevin or retaking, all to the extent that the same
is permitted by law. The Lender may with only such demand, advertising or notice
as may be required by law, sell and deliver any and all Collateral held by it
for its account at any time or times in one or more private or public sales, for
cash or credit or otherwise, at such price and upon such terms as the Lender
deems advisable in its sole discretion. Notice of any public sale shall be
sufficient if it describes the Collateral to be sold in general terms, stating
the amounts thereof and the location and nature of the properties covered by the
security interests and the prior liens thereon, and is published at least once,
not less than seven (7) days prior to the sale, in any newspaper of general
circulation in the locale of the Collateral to be sold which the Lender may
elect. All requirements of reasonable notice shall be met if such notice is sent
to the Borrower, in the manner provided in Section 14.03 below, at least seven
(7) days before the time of such sale or disposition. The Lender may be the
purchaser at any such sale, if it is public, free from any right of redemption.
The proceeds of sale shall be applied first to the costs of retaking,
refurbishing, storing and selling any Collateral hereunder and to other costs of
collection, and then to the payment of obligations of the Borrower to the
Lender. The Lender shall be entitled to apply any collections on account of the
Revolving Note first to fees, costs and charges accrued to the date of receipt,
next to accrued interest and only thereafter to principal. Any excess shall be
returned to the Borrower, and the Borrower shall remain liable for any
deficiency.

     (d) Enforce the provisions of this Agreement by legal proceedings for the
specific performance of any covenant or agreement contained herein or for the
enforcement of any other appropriate legal or equitable remedy, and the Lender
may recover damages caused by any breach by the Borrower of the provisions of
this Agreement, including court costs, reasonable attorneys' fees and other
costs and expenses incurred in the enforcement of the obligations of the
Borrower hereunder.

     (e) Exercise all rights and remedies hereunder, under each of the Notes,
the Security Instruments and under any other agreement with the Lender; and
exercise all other rights and remedies which the Lender may have under
applicable law.

       Section 11.03. Set-off. In addition to any rights now or hereafter
                      -------
granted under applicable

                                       30
<PAGE>

law and not by way of limitation of any such rights, upon the occurrence of any
Event of Default, the Lender is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, all of which are hereby expressly waived, to
set off and to appropriate and apply any and all deposits (general or special)
and any other Indebtedness at any time held or owing by the Lender to or for the
credit or the account of the Borrower against and on account of the obligations
and liabilities of the Borrower to the Lender under this Agreement or otherwise,
irrespective of whether or not the Lender shall have made any demand hereunder
and although said obligations or liabilities, or any of them, may then be
contingent or unmatured and without regard for the availability or adequacy of
other collateral. The Borrower also grants to the Lender a security interest
with respect to all its deposits and all securities or other property in the
possession of the Lender from time to time, and, upon the occurrence of any
Event of Default, the Lender may exercise all rights and remedies of a secured
party under the Uniform Commercial Code.

                                  ARTICLE XII

                     FURTHER PROVISIONS AS TO RECEIVABLES

     Section 12.01. Title to Receivables. The Borrower represents and warrants
                    --------------------
to the Lender that each Receivable will be free and clear of all adverse
interests in favor of any Person other than the Lender. The Borrower represents
and warrants to the Lender that each Qualified Receivable will cover a bona fide
                                                                       ---------
provision of services usually dealt in by the Borrower in the ordinary course of
its business, will be subject to a fully perfected first priority security
interest in favor of the Lender and to no lien in favor of any other Person,
will be for a liquidated amount, will mature as stated in the duplicate invoice
covering such transaction, and will not be subject to any deduction, offset,
counterclaim or other condition other than the Borrower's usual discounts and
ordinary deductions.

     Section 12.02. Furnishing Information.  The Borrower will, at the Lender's
                    ----------------------
request, deliver confirmatory written assignments of Receivables, but the
failure to execute or deliver any such assignment shall not affect or limit the
security interest of the Lender in any Receivable.  Together with each such
assignment, if the Lender so requests, the Borrower will furnish the Lender with
copies of invoices to customers or the equivalent.  The Borrower shall promptly
make, stamp or record such entries or legends on the Borrower's books and
records or on any of the Collateral as the Lender shall request from time to
time to indicate that the Lender has a security interest in such Collateral.

     Section 12.03. Returns; Disputes.  The Borrower shall notify the Lender
                    -----------------
promptly of all material disputes and claims with respect to Receivables.  Other
than in the ordinary course of business, the Borrower shall not settle or adjust
any dispute or claim and no extraordinary discount, credit or allowance shall be
granted without the Lender's consent.  Upon the occurrence of any Event

                                       31
<PAGE>

of Default, the Lender may settle or adjust disputes or claims directly with
customers or account debtors for amounts and upon terms which it considers
advisable. In all cases, the Borrower's account will be credited only with
amounts actually received by the Lender. When the Borrower has received
Collateral of any kind or nature by reason of transactions between itself and
its customers or account debtors, it will hold the same on the Lender's behalf,
subject to the Lender's instructions, and as property forming part of the
Receivables.

     Section 12.04. Collections. After the occurrence of an Event of Default,
                    -----------
the Lender or its designee may at any time notify customers or account debtors
of the Lender's security interest in Receivables, collect the same directly, and
charge the collection costs and expenses to the Borrower's account. Whenever the
Lender deems it desirable that any legal or other action be instituted in order
to effectuate collection of any Receivable, the Lender may at its option
reassign any such Receivable to the Borrower (and any such reassignment shall be
deemed to be without recourse to the Lender in any event) and require the
Borrower to proceed with such legal or other action at the Borrower's sole
liability, cost and expense, in which event all amounts collected by the
Borrower on such Receivable shall nevertheless be subject to this Agreement.

                                 ARTICLE XIII

                         FURTHER RIGHTS OF THE LENDER

     Section 13.01. Further Assurances.  The Borrower shall do all things and
                    ------------------
deliver all instruments reasonably requested by the Lender to protect or perfect
any security interest granted or intended to be granted under the Security
Instruments.  If the Borrower fails promptly to comply with any such request, or
if any Event of Default shall have occurred hereunder, the Borrower authorizes
the Lender to execute, in the name or on behalf of the Borrower, any financing
statement or other document or instrument that the Lender may require to
perfect, protect or establish any security interest or lien interest to which
the Lender may be then entitled and further authorizes the Lender to sign the
Borrower's name on the same.  The Borrower appoints (but only for the purposes
of protecting the Lender's interests in the Collateral or its rights to receive
payments under this Agreement or the Revolving Note or otherwise exercising any
of its rights or causing the performance and fulfillment of the obligations and
agreements intended to be performed and fulfilled by the Borrower) such Person
or Persons as the Lender may designate as the Borrower's attorney-in-fact with
the power to endorse the name of the Borrower on any checks, notes, drafts, or
other forms of payment or security relating to any Collateral that may come into
the possession of the Lender; to sign the name of the Borrower on invoices or
bills of lading, drafts against customers, notices of assignment, verifications
and schedules; to demand, collect, receive payment of, receipt for, settle,
compromise or adjust and give discharges and releases in respect of the
Receivables or any of them; to commence and prosecute any suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect the Receivables or any of them and to enforce any other rights in

                                       32
<PAGE>

respect thereof or in respect of the goods which have given rise thereto; to
defend any suit, action or proceeding brought against the Borrower in respect of
any Receivables or the goods which have given rise thereto, to settle,
compromise or adjust any such suit, action or proceeding and, in connection
therewith, to give such discharges or releases as the Lender may deem
appropriate; to notify the U.S. Postal Service authorities to change the address
of delivery of mail to an address designated by the Lender and to open and
dispose of mail addressed to the Borrower; and, generally, to do all things
necessary to carry out the intent of this Agreement.  This power, being coupled
with an interest, is irrevocable, and the Borrower approves all acts of such
attorney-in-fact.  The powers conferred on the Lender by this Agreement and the
Security Instruments are solely to protect the interest of the Lender and shall
not impose any duty upon the Lender to exercise any such power, and neither the
Lender nor such attorney-in-fact shall be liable for any act or omission, error
in judgment or mistake of law, except for its actual willful misconduct or bad
faith.  The Lender shall have no duty as to the collection or protection of any
Collateral and shall have no duty as to the preservation of rights against prior
parties or any other rights pertaining thereto, except as provided by applicable
law.

     Section 13.02. Right to Cure. In the event that the Borrower shall fail to
                    -------------
purchase or maintain insurance, to pay any tax, assessment, government charge or
levy, except as the same may be otherwise permitted hereunder, or in the event
that any lien, encumbrance or security interest prohibited hereby shall not be
paid in full or discharged, or in the event that the Borrower shall fail to pay
or comply with any other obligation hereunder, the Lender may, but shall not be
required to, pay, satisfy, perform, discharge or bond the same for the account
of the Borrower, and all moneys so paid by the Lender shall be payable on demand
and shall bear interest at the maximum rate in effect and permitted by this
Agreement.

                                  ARTICLE XIV

                                 MISCELLANEOUS

     Section 14.01. No Waiver; Cumulative Remedies.  No failure or delay on the
                    ------------------------------
part of the Lender in exercising any right, power or remedy hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
such right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder.  The remedies herein
provided are cumulative and not exclusive of any remedies provided by law or
otherwise available to the Lender.  The Lender's remedies may be exercised
without resort or regard to any other source of satisfaction of any liabilities
of the Borrower to the Lender.  The provisions of this Agreement are not in
derogation or limitation of any obligations, liabilities or duties of the
Borrower under the Security Instruments or any other agreement with or for the
benefit of the Lender.  No inconsistency in default provisions between this
Agreement and the Security Instruments or any such other agreement will be
deemed to create any additional grace period or otherwise derogate from the

                                       33
<PAGE>

express terms of each such default provision. No covenant, agreement or
obligation of the Borrower contained herein, nor any right or remedy of the
Lender contained herein, shall in any respect be limited by or be deemed in
limitation of any inconsistent or additional provisions contained in the
Security Instruments or any such other agreement.

     Section 14.02. Amendments, Waivers and Consents. Neither this Agreement nor
                    --------------------------------
any provision hereof may be amended, waived, discharged or terminated orally,
but only by a statement in writing signed by the party against whom enforcement
of the amendment, waiver, discharge or termination is sought. Any waiver or
consent may be given subject to satisfaction of conditions stated herein and any
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.
