                                ITEM 1. BUSINESS

Overview

      We design, develop, produce and market sophisticated components and
systems that are used by telecommunication and defense systems and
telecommunications service providers in a broad range of applications. Revenue
growth over the past five years has been driven by the global expansion of
telecommunications services such as satellite systems, cable television,
cellular telephone systems, PCS telephony and the Internet. We meet the high
performance requirements of our telecommunications customers by drawing upon
proprietary expertise in key microwave amplification and transmission
technologies developed over more than 32 years of operations.

      A majority of our sales in fiscal 1999 were of products developed by us
within the last 5 years, including, for example, linear amplifiers sold to
cellular and PCS telephony system manufacturers for testing their systems'
amplifiers, and turbo codec modems sold to satellite systems integrators and
service providers for use in voice, data, video and fax transmission. Our
internally funded and customer funded research and development expenses
aggregated $3.8 million, $1.7 million and $1.5 million in fiscal 1999, 1998 and
1997, representing 10.0%, 5.6% and 6.0% of our net sales in those fiscal years.

      We conduct our business through three decentralized but complementary
product and service segments: telecommunications transmission, RF microwave
amplifiers, and our development-stage mobile data communication services
business that we acquired in 1998.

            Telecommunications transmission -- modems, frequency up converters
      and down converters, solid state, high-power amplifiers, satellite very
      small aperture (VSAT) transceivers and antennas for satellite ground
      station applications and adaptive modems and microwave radios for
      over-the-horizon microwave communications systems. Customers include,
      among others, satellite systems integrators and communication service
      providers and oil companies.

            RF microwave amplifiers -- solid state, high-power, broadband
      amplifier products in the microwave and radio frequency (RF) spectrums for
      a wide range of applications, including testing amplifiers used in the
      cellular and wireless industries and amplifiers in jamming and
      identification, friend or foe (IFF) defense systems. Customers include,
      among others, communication service providers, cellular and PCS telephony
      manufacturers and defense contractors.

            Mobile data communications services -- Secure, real time two-way
      messaging links between mobile platforms, such as land vehicles, rail and
      aircraft, remotely placed fixed site sensors and user headquarters through
      our Germantown, Maryland gateway satellite earth station. The network
      employs leased satellite capacity and direct line or Internet links
      between our gateway and user headquarters. Depending upon the end-user's
      needs, our system can be configured to provide a wide range of non-voice
      applications, ranging from simple location tracking to messaging, e-mail,
      broadcasting of information, meter and other sensor reading, and monitor
      and control of gauges and sensors.

            In June 1999, the U. S. Army awarded us a contract which, subject to
      government funding and deployment decisions, provides for the purchase of
      up to $418.2 million in mobile transceiver units and global data messaging
      communication services over an eight-year period. We have not yet received
      significant orders under this contract, which can be terminated by the
      U.S. Army at any time for its convenience, and we cannot assure you that
      we will receive any such orders.

            Sales for use by international customers represented approximately
      60.1%, 46.5%, and 57.3% of our net sales in fiscal years 1999, 1998 and
      1997, respectively. We believe that the global expansion of


                                       1
<PAGE>

telecommunications, particularly in developing countries in Asia, South America,
the Middle East and Europe, represents a key opportunity for the continued
growth of our telecommunications business. Included as international sales are
sales made to domestic companies for inclusion in products which will be sold to
international customers.

      Our product designs are based on both analog and digital microwave
technologies. Digital microwave technology can significantly enhance performance
of telecommunications systems. We have invested significant resources in
developing our technological expertise, and work closely with customers and
potential customers to develop product lines in market niches where we believe
our expertise can enable us to become a leading supplier.

      Our three business segments -- telecommunications transmission, RF
microwave amplifiers and our development-stage mobile data communications
services business -- operate through individual operating units, each of which
maintains its own sales, marketing, product development and manufacturing
functions. We believe that this organizational structure allows the key
personnel of each operating unit to be more responsive to their particular
markets and customers. Brief descriptions of our business segments and operating
units follow.

Telecommunications Transmission Business Segment

      The demand for telecommunications is increasing worldwide as emerging
economies seek to modernize their infrastructure and as increasingly
information-intensive markets introduce new telecommunications services. The
telecommunications industry has expanded rapidly during the last decade due to
technological advances and deregulation. Advances in technology have lowered
per-unit communications costs, increased product reliability and encouraged a
proliferation of new and enhanced communications products and services.

      In making procurement decisions, customers for telecommunications
equipment must weigh the relative costs and advantages of the six presently
available transmission technologies: copper cable, fiber optic cable, high
frequency radio systems, wireless microwave systems, over-the-horizon microwave
systems and satellite systems. Rarely is a complete communications network or
system based solely on one of these technologies. Transmission can be routed
through a combination of technologies, each employed where most cost-effective.
Our products are used in satellite, over-the-horizon microwave, terrestrial
line-of-sight microwave and wireless.

            Satellite communications systems have grown and diversified in
            response to demand for efficient and accurate long distance voice
            and video communication and digital information exchange. In a
            satellite communications system, information is relayed to and from
            microwave transmitting and receiving stations on the ground by means
            of a low earth orbit (LEO), medium earth orbit (MEO), or
            geostationary earth orbit (GEO) satellites, which are generally
            placed in an orbit from 600 to 22,300 miles above the earth's
            equator. Satellite communications systems are particularly useful
            where long-range, high capacity and high quality point-to-point or
            point-to-multipoint communication is desirable. As few as three GEO
            satellites can provide global communications coverage. These
            systems, which use microwave technology, are well suited for rapid
            introduction of service in remote areas or where communication
            alternatives are unavailable, such as mobile, shipboard or defense
            applications.

            Over-the-horizon microwave communication systems transmit signals
            over distances from 30 to 600 miles by reflection of the transmitted
            signals off the troposphere, an atmospheric layer located
            approximately seven miles above the earth's surface. The net effect
            is that the signal is reflected by a large number of scattering
            particles in the troposphere which, in turn, directs a portion of
            the transmitted signal energy well beyond line-of-sight. Such
            systems offer a high level of reliability and security.

            Wireless and line-of-sight microwave communications systems,
            generally used for point-to-point communications, employ signals
            with extremely short wave-lengths which travel only in line-of-sight
            paths over relatively short distances, generally under 30 miles, can
            be quickly and easily installed, require relatively low initial
            capital investment and can be upgraded and expanded over time.


                                       2
<PAGE>

            High frequency (HF) radio systems employ long wavelengths which are
            propagated beyond line-of-sight distances either by surface waves
            traveling along the earth's perimeter or by skywave reflection of
            the transmitted waves off different layers of the ionosphere.

            Fiber optic cable is best suited to high-volume, point-to-point,
            short- or long-distance links where its advantages -- capacity,
            quality and security -- justify the long lead time and high cost to
            equip and install a network.

            Copper cable, the traditional transmission medium most familiar to
            consumers, is being replaced and supplemented by the other media,
            particularly for high-volume and long distance transmissions where
            it has substantial capacity, cost and reliability limitations.

      Our Comtech Systems, Inc. subsidiary, located in St. Cloud, Florida,
designs, markets, manufactures and installs telecommunication products for
domestic and international applications. It also supplies telecommunication
systems by combining its products with equipment manufactured by our other
Comtech operating units and third parties.

      Comtech Systems Inc.'s product line consists primarily of equipment for
over-the-horizon microwave systems and networks. It has a turnkey capability
that ranges from system and network planning through equipment and system
training and operation and maintenance programs. Comtech Systems Inc.'s markets
its products and services to oil and gas companies and other commercial users,
foreign defense commands and system prime contractors. We believe that Comtech
Systems Inc.'s products, which employ adaptive modem digital transmission
technology, offer high-speed data benefits over the traditional analog
over-the-horizon microwave products offered by most of its competitors.

      Our Comtech Communications Corp. subsidiary located in Tempe, Arizona,
designs and manufactures equipment used in commercial and defense satellite
communications. The equipment includes modems, frequency up converters and down
converters, solid state power amplifiers and satellite VSAT transceivers, which
combine our frequency converters with solid state, high-power amplifiers. These
products comprise a broad range of receiving and transmitting equipment offering
a variety of state-of-the-art technical capabilities with respect to
performance, complexity and value. Comtech Communications Corp. recently
introduced its own turbo codec modem product line. This forward error correction
solution offers significantly improved performance, power and bandwidth
performance over traditional systems.

      Our Comtech Antenna Systems, Inc. subsidiary, located in St. Cloud,
Florida, designs, manufactures, and markets a wide variety of fiberglass and
aluminum antennas for over-the-horizon microwave and satellite communication
applications, including distributed network programming, cable and broadcast
television and radio as well as other forms of information and entertainment
distribution. Comtech Antenna Systems, Inc. designs antennas for specific types
of telecommunications systems and, typically, sells standardized products to
independent distributors, prime contractors and end user customers. Comtech
Antenna Systems Inc.'s antenna product line includes fixed and mobile antenna
systems and specialized multi-beam satellite antenna systems that are capable of
receiving signals simultaneously from many independent satellites located up to
60 degrees apart.

RF Microwave Amplifier Business Segment

      Amplifiers are a class of electronic apparatus that reproduce signals with
greater power, current or voltage amplitude. Indispensable in the world of
signal processing, amplifiers can be as tiny as a microchip for a hearing aid or
as massive as a multi-story building for transmitting radio signals to submerged
submarines or to outer space. Although the majority of amplifier applications
are satisfied by solid state transistor and integrated circuit technology,
vacuum tubes still play an important role in the very high-power microwave
applications. Because of their greater instantaneous bandwidths, greater
reliability and generally smaller size, however, solid state amplifiers are
constantly being sought as replacements for vacuum tube amplifiers for all
applications throughout the useable frequency spectrum.


                                       3
<PAGE>

      We are one of a small number of companies producing solid state,
high-power, broadband RF amplifier products that use the microwave and radio
frequency (RF) spectrums in a wide range of applications. Our products amplify
energy for applications including wireless, telecommunications, instrumentation,
and defense systems.

      In telecommunications, solid state, high power amplifiers are used to
amplify signals for radiation from transmitting antennas in satellite or other
wireless telecommunications systems. They are also used to amplify signals in
defense and airport radar and electronic jamming systems. In the laboratory,
solid state, high-power amplifiers are used to test the performance of
high-power microwave and wireless electronic system components by simulating
operating environment conditions.

      Solid state, high-power amplifiers are also used in electromagnetic
compatibility and susceptibility testing. The proliferation of electronic
systems in products such as automobiles, computers, wireless telephones, radios,
televisions, medical equipment, sound amplifiers, aircraft and other products
has led to increasingly serious problems with electromagnetic interference.
Manufacturers, therefore, test these electronic systems for electromagnetic
compatibility and susceptibility using solid state, high-power RF microwave
amplifiers such as those we manufacture. For example, such testing may be used
to determine whether the various electronic systems in a commercial aircraft are
likely to be affected by the use of laptop computers, wireless telephones or
video games by passengers in flight.

      Our Comtech PST Corp. subsidiary, located in Melville, New York, designs,
develops, manufactures and markets solid state, high-power large signal
amplifiers in the microwave and RF spectrums for communications, defense and
instrumentation applications where they are employed to amplify microwave or RF
energy for the emission of signal. Comtech PST Corp. sells its products to
domestic and foreign commercial users, governmental agencies and prime
contractors. We believe it is an innovative supplier of solid state, high-power
amplifiers and related power processing equipment, which also replace amplifiers
using vacuum tube systems.

Mobile Data Communications Services Business Segment

      The demand for mobile data communications services and products has
increased dramatically over the past years for both government and commercial
applications. This demand is driven by digital technology advances coupled with
the desire to locate, track, manage, monitor and communicate with mobile and
fixed assets. The transmission of these services may be done over various
systems, i.e., terrestrial, cellular or satellite, depending on the most
cost-effective approach to meet the application's requirements.

      Through our Comtech Mobile Datacom Corp. subsidiary, we have developed and
have begun marketing a satellite-based data communications system for the land
transportation, remote sensing, utility and aviation markets. Applications
include asset tracking (using information obtained from the Global Positioning
Satellite system), two-way mobile messaging, e-mail and automated reading of
sensors including meters and gauges. Through our satellite earth station gateway
in Germantown, Maryland, we can route signals to and from mobile or fixed,
remote terminals via leased satellite. Customers can access their message or
data through an Internet connection or a direct line to their personal web
sites. We developed our system, including our mobile terminals and the software
to operate our gateway data processing system, through a combination of internal
development and government contract funding.

      Comtech Mobile Datacom Corp. acquired the assets of its predecessor
company, Mobile Datacom Corp., in 1998. Mobile Datacom Corp. was formed in 1993
by its President and CEO, Joel R.Alper, along with a number of senior executive
and technical personnel formerly employed by COMSAT Corp., which transferred its
mobile data communication technology to Mobile Datacom Corp. and provided a
portion of its initial funding for the company. Over the intervening years,
Mobile Datacom Corp. made successive improvements in its technology through
development contracts with a variety of government agencies, and provided
limited commercial services in the land transportation and aviation markets.

      In early 1999, Comtech Mobile Datacom Corp. lead a multi-company team in
competing for the U.S. Army's Movement Tracking System, a system to be deployed
by the Army for global use in tracking its assets and communicating by message
in real time with these vehicles from fixed and mobile command centers. The
contract was awarded to Comtech Mobile Datacom Corp. in June 1999. The contract
allows for purchases of up to $418.2 million of equipment and services over an
eight-year period, and is also open to other government agencies to procure
their tracking and messaging requirements. In September 1999, Comtech Mobile
Datacom completed the


                                       4

first major milestone in the contract, a validation demonstration involving
communicating between mobile terminals in Germany and Texas, over two satellite
links with the respective ground stations interconnected via the Internet.

Sales, Marketing and Customer Support

      Each of our operating units conducts its own sales and marketing efforts.
In some instances, our operating units may bundle other units' products. Sales
and marketing strategies vary with particular markets served and include direct
sales through sales, marketing and engineering personnel, sales through
independent representatives, value-added resellers or a combination of the
foregoing. Our operating units enter into sales distribution agreements for
certain products with distributors. Unlike sales representatives, who merely
find customers on a commission basis, some of our distributors purchase products
from us for resale. We intend to continue to expand domestic and international
marketing efforts through both independent sales representatives, distributors
and value-added resellers.

      Our management, technical and marketing personnel establish and maintain
relationships with customers. Our strategy includes a commitment to provide
ongoing customer support for our systems and equipment. This support involves
providing direct access to engineering staff or trained technical
representatives to resolve technical or operational problems.

      Our international sales from all three business segments represented
approximately 60.1%, 46.5% and 57.3% of total net sales in fiscal 1999, 1998 and
1997, respectively. International sales are expected to continue to increase due
to the global expansion of telecommunications and microwave instrumentation and
we expect that international sales will remain a substantial portion of our
total sales for the foreseeable future.

      Domestic commercial sales represented approximately 24.3%, 34.0% and 25.7%
and U.S. government sales represented 15.6%, 19.5% and 17.0% of our net sales in
fiscal 1999, 1998 and 1997, respectively.

      Sales to one customer in fiscal 1999 and to different customers in fiscal
1998 and 1997 represented 27.0%, 12.2% and 10.2% of our consolidated net sales,
respectively.

Compliance with Federal, State and Local Environment Protection Laws

      We are subject to a variety of local, state and federal governmental
regulations relating to the storage, discharge, handling, emission, generation,
manufacture and disposal of toxic or other hazardous substances used to
manufacture our products, particularly in connection with the fabrication of
fiberglass antennas by Comtech Antenna Systems, Inc. We believe that we are
currently in compliance in all material respects with such regulations and that
we have obtained all necessary environmental permits to conduct our business. To
date, compliance with federal, state or local environment protection laws has
not had a material effect on our capital expenditures, earnings or competitive
position, and we do not expect that such compliance will have a material effect
in the future.

Backlog

      Our backlog as of July 31, 1999 and 1998 was approximately $38.6 million
and $15.4 million, respectively. We expect that a substantial majority of the
backlog as of July 31, 1999 will be recognized as sales during fiscal 2000. We
received payments in respect of progress billings and advance payments
aggregating approximately $2.9 million as of July 31, 1999 in connection with
orders included in the backlog at that date. Approximately 2.7% of that backlog
consisted of U.S. government contracts, subcontracts and government funded
programs, approximately 92.1% consisted of orders for use by foreign customers
or domestic companies whose products will be sold to foreign customers and
approximately 5.2% consisted of orders for use by domestic commercial customers.
Our backlog at July 31, 1999 included a $100,000 funded order under the Mobile
Datacom Corp.'s contract with the U.S. Army.

      Our backlog consists solely of orders believed to be firm. In the case of
contracts with departments or agencies of the U.S. government, orders are only
included in backlog to the extent funding has been obtained for such orders. All
of the contracts in our backlog are subject to cancellation at the convenience
of the customer or for default in the event that we are unable to perform the
contract.


                                       5
<PAGE>

      Variations in backlog from time to time are attributable, in part, to the
timing of our preparation and submission of contract proposals, the timing of
contract awards and the delivery schedules on specific contracts. As a result,
we believe our backlog at any point in the fiscal year is not necessarily
indicative of the total sales anticipated for any particular future period. Our
Comtech Antenna and Comtech Communications businesses, as well as a significant
portion of Comtech PST's business, operate under short lead times and usually
generate sales out of inventory.

Manufacturing and Service

      Our manufacturing operations consist principally of the assembly and
testing of electronic products we design and build from purchased fabricated
parts, printed circuits and electronic components and, in the case of antennas,
the casting of fiberglass antennas. We employ formal quality management programs
and other training programs, including International Standards Organization's
(ISO 9000) quality procedure registration programs. Our Comtech PST Corp.
operating unit has been qualified for ISO 9001 and we are in the process of
qualifying our other operating units.

      Our ability to deliver products to customers on a timely basis is
dependent, in part, upon the availability and timely delivery by subcontractors
and suppliers of the components and subsystems that are used by us in
manufacturing our products. Electronic components and raw materials used in our
products are generally obtained from independent suppliers. Some components are
standard items and are available from a number of suppliers. Others are
manufactured to our specifications by subcontractors. We obtain certain
components and subsystems from a single source or a limited number of sources.
We believe that most components and equipment are available from existing or
alternative suppliers and subcontractors. A significant interruption in the
delivery of such items could have a material adverse effect on our business and
results of operations. See "Mobile Data Communications Services Business
Segment" for a further description of manufacturing operations in that segment.

      The technology used in our products is subject to rapid development and
frequent change. Our business position is in large part contingent upon the
continuous refinement of our scientific and engineering expertise and the
development, either through internal research and development or acquisitions,
of new or enhanced products and technologies.

      We reported research and development expenses of $2.0 million, $1.3
million and $1.0 million in fiscal 1999, 1998 and 1997, respectively,
representing 5.3%, 4.4% and 4.1% of total net sales, respectively, for such
years. A portion of our research and development efforts relates to the
adaptation of our basic technology to specialized customer requirements and is
recoverable under such contracts, and such expenditures are not included in our
research and development expenses for financial reporting purposes. During
fiscal 1999, 1998 and 1997, we were reimbursed by customers for such activities
in the amounts of $1.8 million, $356,000 and $436,000, respectively.
Accordingly, our aggregate research and development expenditures (internal and
customer funded) were 10.0%, 5.6% and 6.0% of net sales in fiscal 1999, 1998 and
1997, respectively.

Patents and Licenses

      Although we own or hold licenses for a number of patents, patents and
licenses have been of substantially less significance in our business than our
scientific and engineering know-how, production techniques, the timely
application of our technology and the design development and marketing
capabilities of our personnel. We rely on the laws of unfair competition,
restrictions in licensing agreements and confidentiality agreements to protect
such knowledge and techniques.


                                       6

Competition

      Our businesses are highly competitive and characterized by rapid
technological change. In addition, the number of potential customers for our
products is limited. Our growth and financial condition depend, among other
things, on our ability to keep pace with such changes and developments and to
respond to the sophisticated requirements of an increasing variety of electronic
equipment users. Many of our competitors are substantially larger, have
significantly greater financial, marketing, research and development,
technological and operating resources and broader product lines than we do. A
significant technological breakthrough by others, including smaller competitors
or new companies could have a material adverse effect on our business. In
addition, certain of our customers have technological capabilities in our
product areas and could choose to replace our products with their own should
they decide it would be advantageous for them to do so.

      In the market for mobile data communications services, there are several
much larger competitors with existing systems. The most prominent of these
competitors is Qualcomm Incorporated, which has sold over 250,000 mobile units
and provides messaging and maintenance services to over 850 transportation
companies in the United States alone. Existing competitors are aggressively
pricing their products and services and may continue to do so in the future. We
anticipate that new competitors will enter the market in the future. Competitors
continue to offer new value-added products and services, which we may be unable
to match on a timely or cost-effective basis. Increased competition may impact
margins throughout the industry.

      We believe that competition in our telecommunications transmission and RF
amplifier business segments' markets is based primarily on price, product
performance, reputation, delivery times and customer support. Due to our
decentralized organizational structure and proprietary know-how, we believe we
have the ability to develop, produce and to deliver equipment on a
cost-effective basis faster than many of our competitors.

Key Personnel/Employees

      We believe our success is dependent upon the continued contributions of
our key management personnel, including the key management at each of our
operating units, and depends to a significant extent upon our President and
Chief Executive Officer, Fred Kornberg. Many of our key personnel, particularly
the key engineers, would be difficult to replace, and are not subject to
employment or non-competition agreements. The development of our mobile data
communications services business is particularly dependent upon Joel R. Alper,
the President of Comtech Mobile Datacom. Our growth and future success will
depend in large part upon our ability to attract and retain highly qualified
engineering, sales and marketing personnel. Competition for such personnel from
other companies, academic institutions, government entities and other
organizations is intense. Although we believe we have been successful to date in
recruiting and retaining key personnel, we may not be successful in attracting
and retaining the personnel we require in order to continue to grow and operate
profitably. The management skills that have been appropriate for our business in
the past may not continue to be appropriate if our business continues to grow
and diversify.

      At July 31, 1999, we had 268 employees, 132 of whom were engaged in
production and production support, 89 in research and development and other
engineering support and 49 in marketing and administrative functions. None of
the employees are represented by a labor union. We believe that our employee
relations are good.

Disclosure Regarding Forward-Looking Statements

      The Private Securities Litigation Reform Act of 1995 provides for
forward-looking statements. Certain information in Items 1,2,3,7 and 8 of this
Form 10-K include information that is forward-looking, such as our anticipated
sales levels, our anticipated liquidity and capital requirements and the results
of legal proceedings. The matters referred to in forward-looking statements
could be affected by the risks and uncertainties involved in our business. These
risks and uncertainties include, but are not limited to, the effect of economic
and market conditions, unpredictable reductions in funding for government
defense expenditures, and the risks associated with international sales,
including fluctuations in foreign currency exchange rates, political and
economic instability, availability of suitable export financing, export license
requirements, tariff regulations and other U.S. and foreign regulations that may
apply to the export of our products, as well as certain other risks described
above in this Item under "Backlog,"

"Competition" and "Key Personnel/Employees" and below in Item 3 in "Legal
Proceedings" and in Item 7 in "Management's Discussion and Analysis of Financial
Condition and Results of Operations." Subsequent written and oral
forward-looking statements attributable to us or persons acting on our behalf
are expressly qualified in their entirety by the cautionary statements in this
paragraph and elsewhere in this Form 10-K.

                               ITEM 2. PROPERTIES

      Our corporate offices are located in a portion of the 46,000-square foot
facility on two acres of land in Melville, New York which also houses Comtech
PST.

      We lease the facility in Melville, New York from a partnership controlled
by our Chairman, Chief Executive Officer and President. The lease, as amended,
provides for our exclusive use of the premises as they now exist for an initial
term of ten years through December 2001. We have the option to extend the term
of the lease for an additional ten-year period and a right of first refusal in
the event of a sale of the facility. The base annual rental under the lease is
subject to adjustments. We believe that the terms of this lease are not less
advantageous to us than those that would have been available to us from an
unrelated party.

      We lease the 32,000-square foot facility on eight acres of land used by
Comtech Antenna Systems, Inc. and Comtech Systems, Inc. in St. Cloud, Florida
from a Florida land trust controlled by our Senior Vice President and Chief
Financial Officer. The lease provides for our exclusive use of the premises as
they now exist for a term expiring September 2003. We have the option to extend
the term of the lease for an additional five-year period. The base annual rental
under the lease is subject to adjustments. We believe that the terms of this
lease are not less advantageous to us than those that would have been available
to us from an unrelated party.

      We lease a 20,000-square foot building in Tempe, Arizona for our Comtech
Communications Corp. operating unit from an unrelated third party. The lease
provides for the exclusive use of the premises as they now exist for a term of
three years through April 2001.

      We lease 7,100-square feet of space located in Germantown, Maryland that
is used by Comtech Mobile Datacom Corp. from an unrelated third party. This
lease provides for the exclusive use of the premises as they now exist through
August 2004. We have a one-time option to terminate the lease effective August
31, 2003 by providing at least six months' notice and paying $17,500. The base
annual rental under this lease is subject to adjustments.

                            ITEM 3. LEGAL PROCEEDINGS

      We are subject to certain legal actions which arise out of the normal
course of business. We believe that the outcome of these actions will not have a
material effect on our consolidated financial position or results of operations.

           ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      No matters were submitted to our stockholders during the fourth quarter of
the fiscal year ended July 31, 1999.

Dividends

      We have never paid cash dividends on our common stock and we intend to
continue this policy for the foreseeable future. We expect to use earnings to
finance the development and expansion of our business. Our Board of Directors
reviews our dividend policy periodically. The payment of dividends in the future
will depend upon our earnings, capital requirements, financial condition and
other factors considered relevant by our Board of Directors.

Approximate Number of Equity Security Holders

      As of October 22, 1999, there were approximately 770 holders of the
Company's common stock. Such number of record owners was determined from the
Company shareholders' records and does not include beneficial owners of the
Company's common stock held in the names of various security holders, dealers
and clearing agencies.

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

Overview

            We design, develop, produce and market sophisticated components and
systems that are used by telecommunication and defense systems and
telecommunications service providers in a broad range of applications. A
substantial portion of our business is derived from a limited number of
relatively large customer contracts, the timing of which cannot be predicted.
Accordingly, we experience significant fluctuations in sales and operating
results from quarter to quarter.

      Our business consists of three segments: telecommunications transmission;
RF microwave amplifiers; and mobile data communications services, which is a
development-stage business. We began reporting financial results on a segment
basis in fiscal 1999. Our sales are made to domestic and international
customers, both commercial and governmental. International sales are expected to
increase in the foreseeable future due to the growing worldwide demand for
wireless and satellite telecommunications and our expanded line of product
offerings to meet these demands.

      Sales consist of stand-alone products and systems, although for the past
five years we have endeavored to achieve greater product sales as a percentage
of total sales, due to generally higher gross profit margins on products rather
than systems.

      We generally recognize income under contracts only when the products are
shipped. However, when the performance of a contract will extend beyond a
12-month period, income is recognized on the percentage-of-completion method.

      Our gross profit is affected by a variety of factors, including the mix of
products, systems and equipment sold, production efficiency and price
competition.

      Selling, general and administrative expenses consist primarily of salaries
and benefits for marketing, sales and administrative employees, advertising and
trade show costs, professional fees and amortization of deferred compensation.
Deferred compensation consists of restricted stock awards granted to certain
operating management personnel. Under these grants, the employees purchased
shares of our common stock at prices representing a discount to the then market
value. The stock is subject to certain restrictions which lapse after ten years
and which may be removed earlier upon achievement of certain business unit
performance goals.

      Our research and development expenses relate to both existing product
enhancement and new product development. A portion of our research and
development efforts is related to specific contracts and is recoverable under
those contracts because they are funded by the customers. Such customer-funded
expenditures are not included in research and development expenses for financial
reporting purposes but are reflected in cost of sales.

      As of the end of fiscal 1998, we had a 100% valuation allowance against
our gross deferred tax assets. During fiscal 1999, based on our assessment of
the recoverability of the deferred tax assets, we concluded that a full
valuation allowance was no longer necessary given our estimates of future
earnings and the expected timing of temporary difference reversals. Accordingly,
we reduced the valuation allowance to $777,000 and recorded a corresponding
one-time $4.6 million benefit for income taxes in fiscal 1999.

      In the first quarter of fiscal 1999, through newly formed wholly-owned
subsidiaries Comtech Mobile Datacom, our Mobile data communications services
business, and Comtech Wireless, Inc., our wireless local loop business, we
acquired the assets and assumed certain liabilities of two businesses. Both
acquisitions were accounted for using the purchase method of accounting. The
goodwill resulting from the purchase of the mobile data communications services
business (i.e., the excess of the purchase price over the fair value of the net
assets acquired and liabilities assumed) is being amortized over a 20-year
period. In June 1999, the U.S. Army awarded us a contract which, subject to
government funding and deployment decisions, provides for the purchase of up to
$418.2 million in mobile terminal units and global data communications services
over an eight-year period. Although sales will be dependent upon annual
government funding we are anticipating there will be sales under this


                                       11
<PAGE>

contract in fiscal 2000. Sales for the mobile data communications segment in
fiscal 1999 were approximately $300,000.

      Comtech Wireless, Inc. designs and manufactures wireless local loop
systems for the rural and remote telephony market. Due to disappointing results
and uncertain prospects, in September 1999 the Board of Directors approved a
plan to liquidate Comtech Wireless, Inc. by January 31, 2000 and the results of
operations for the segment have been shown as a discontinued operation in the
consolidated financial statements as of and for the year ended July 31, 1999.
Comtech Wireless, Inc. did not have any sales in fiscal 1999 and negligible
revenues are anticipated in fiscal 2000.

Results of Operations

      The following table sets forth, for the periods indicated, certain income
and expense items expressed as a percentage of our net sales:

Comparison of Fiscal 1999 and 1998

Net Sales Consolidated net sales were $37.9 million and $30.1 million for fiscal
1999 and 1998, respectively, representing an increase of $7.8 million or 25.8%.
This increase was due primarily to increased sales by our telecommunications
transmission segment of over-the-horizon microwave equipment, principally to one
customer, a major U.S. prime contractor. Total sales to this customer during
fiscal 1999 were approximately $10.2 million, representing 27.0% of the total
net sales. The total order received from this customer in fiscal 1999 was
approximately $42.5 million and the contract balance of approximately $32.3
million is expected to be recognized as revenue in fiscal 2000 and 2001. There
were no other customers for which total sales in fiscal 1999 represented 10% or
more of net sales. In fiscal 1998, sales to a different customer represented
12.2% of total net sales. Included in the telecommunications transmission
segment are sales of our satellite equipment products, which increased in fiscal
1999 by approximately 65.8%, due to additional product offerings. Sales from our
RF microwave amplifier segment declined by approximately 14.9% compared to
fiscal 1998, due to the timing of receipt of follow-on orders. International
sales increased by approximately $8.8 million or 62.7%, representing 60.1% and
46.5% of total net sales for fiscal 1999 and 1998, respectively. Domestic sales
decreased by $1.0 million or 9.9%, representing 24.3% and 34.0%, of total net
sales for fiscal 1999 and 1998, respectively. U.S. government sales increased by
$20,000 or .3%, representing 15.6% and 19.5% of total net sales for fiscal 1999
and 1998, respectively.

Gross Profit Gross profit was $11.5 million and $8.8 million for fiscal 1999 and
1998, respectively, representing an increase of $2.7 million or 30.7%. The
increase was due primarily to the increase in sales volume in fiscal 1999
compared to fiscal 1998. Gross margin as a percentage of net sales was 30.3% and
29.2% in fiscal 1999 and 1998, respectively, due primarily to increased sales of
products coupled with lower per unit costs.

Selling, General and Administrative Selling, general and administrative expenses
were $6.6 million and $6.0 million in the fiscal 1999 and 1998, respectively,
representing an increase of $619,000 or 10.3%. This increase


                                       12
<PAGE>

was due primarily to higher sales commissions, marketing personnel expenses,
deferred compensation and other administrative expenses. As a percentage of net
sales, these expenses were 17.5% and 20.0% in fiscal 1999 and 1998,
respectively. Although increased expenses were required to support the higher
sales volume in fiscal 1999 compared to fiscal 1998, these expenses increased at
a lower rate than the increase in sales. In addition, the increased expenditures
reflect those required by our mobile data communications services segment which
was formed in fiscal 1999.

Research and Development Research and development expenses were $2.0 million and
$1.3 million in fiscal 1999 and 1998, respectively, representing an increase of
$703,000 or 53.3%. We are continually enhancing and developing new products and
technologies. In fiscal 1999, the research and development expenses were
primarily for developing additional satellite product offerings and redesigning
components of over-the-horizon microwave products. Whenever possible, we seek
customer funding for research and development to adapt our products to
specialized customer requirements. During fiscal 1999 and 1998, we were
reimbursed $1.8 million and $356,000, respectively, which amounts are not
reflected in the reported research and development expenses.

Operating Income As a result of the foregoing factors, we had operating income,
from continuing operations, of $2.8 million and $1.5 million in fiscal 1999 and
1998, respectively, representing an increase of $1.4 million or 94.7%.

Interest Expense Interest expense was $204,000 and $234,000 for fiscal 1999 and
1998, respectively, representing a decrease of $30,000 or 12.8%. Interest
expense in both years was due primarily to interest associated with our capital
lease obligations.

Interest Income Interest income was $65,000 and $36,000 for fiscal 1999 and
1998, respectively, representing an increase of $29,000 or 80.6%. The increase
was due primarily to the increase in the amount of cash available to invest in
fiscal 1999 as compared to fiscal 1998. Interest income was primarily derived
from the cash on hand in excess of working capital requirements that is invested
in highly liquid, short-term money-market funds consisting primarily of direct
obligations of the U.S. government.

Income Taxes The benefit for income taxes applicable to continuing operations in
fiscal 1999 was $3.8 million compared to the provision for income taxes of
$180,000 in fiscal 1998. Due to our net operating loss carryforwards and other
temporary differences between recognition of income for financial reporting and
income tax purposes, we had deferred tax assets of $5.4 and $5.3 million in
fiscal 1999 and 1998, respectively. As of July 31, 1998, we assessed a 100%
valuation allowance against this deferred tax asset. During fiscal 1999, we
concluded that a full valuation allowance was no longer necessary given our
estimates of future earnings based on substantial new contracts entered into and
the expected timing of temporary difference reversals. Accordingly, we reduced
the valuation allowance to $777,000 during fiscal 1999. The effect of this
change resulted in a tax benefit to us in fiscal 1999 of $4.6 million, which was
partially offset by the provision for the current year's income tax expense.

Discontinued Operations In September 1999, we adopted a plan, effective as of
July 31, 1999, to liquidate the wireless local loop business. The loss from
operations, net of a tax benefit, for fiscal 1999, was $622,000. The loss on the
disposition of the segment, net of a tax benefit, was $594,000, which includes a
provision of $430,000 for operating losses expected to be incurred during the
phase-out period. The liquidation is expected to be completed by January 31,
2000.

Comparison of Fiscal 1998 and 1997

Net Sales Consolidated net sales were $30.1 million and $24.7 million in fiscal
1998 and 1997, respectively, representing an increase of $5.4 million or 21.7%.
This increase was due primarily to increased domestic and U.S. government sales
of high-power amplifiers and increased international sales of over-the-horizon
microwave equipment, partially offset by decreased international sales of
satellite communication products. International sales decreased by approximately
$184,000 or .6% representing 46.5% and 57.3% of total net sales for fiscal 1998
and 1997, respectively. Domestic sales increased by $2.9 million or 60.9%
representing 34.0% and 25.7% of total net sales. U.S. government sales increased
by $1.7 million or 39.9% representing 19.5% and 17.0% of total net sales in
fiscal 1998 and 1997, respectively. Sales to one customer in fiscal 1998 and
sales to different customers in fiscal 1997 represented 12.2% and 10.2% of
consolidated net sales for fiscal 1998 and 1997, respectively.


                                       13
<PAGE>

Gross Profit Gross profit was $8.8 million and $7.1 million for fiscal 1998 and
1997, respectively, representing an increase of $1.7 million. The primary reason
for this increase was a net increase in sales volume in fiscal 1998. Gross
profit, as a percentage of net sales, was relatively unchanged.

Selling, General and Administrative Selling, general and administrative expenses
were $6.0 million and $5.4 million in fiscal 1998 and 1997, respectively,
representing an increase of $598,000 or 11%. This increase was due primarily to
the increased expenses required to support the higher level of sales in the
fiscal 1998 period, including higher bid and proposal expenses, sales
commissions, marketing personnel expenses and other administrative expenses. As
a percentage of sales, however, these expenses decreased to 20.0% in fiscal
1998, from 21.9% in fiscal 1997.

Research and Development Research and development expenses were $1.3 million and
$1.0 million in fiscal 1998 and 1997, respectively, representing an increase of
$296,000 or 28.9%. Research and development expenses as a percentage of net
sales were 4.4% and 4.1%. This increase was primarily due to increased expenses
for general product improvements and for the development of a CSAT transceiver
and VSAT modem and a complement of additional product offerings to the
"fly-away" and "quick deployment" antenna product lines. Whenever possible, we
seek customer funding for research and development to adapt our products to
specialized customer requirements. During fiscal 1998 and 1997, we were
reimbursed $356,000 and $436,000, respectively, which amounts are not reflected
in the reported research and development expenses.

Operating Income As a result of the foregoing factors, we reported operating
income of $1.5 million in fiscal 1998 compared to operating income of $638,000
in fiscal 1997, representing an increase of $814,000 or 127.6%.

Interest Expenses Interest expense was $234,000 and $284,000 in the fiscal 1998
and 1997, respectively. Interest expense in both years was due primarily to
interest associated with our capital lease obligations.

Interest Income Interest income for fiscal 1998 and 1997 was $36,000 and
$33,000, respectively. This increase was due primarily to the increase in the
amount of cash available to invest in fiscal 1998. Interest income in fiscal
1997 included approximately $14,000 that was received from a customer for
extended payment terms.

Other Income We reported other income of $30,000 and $151,000 in fiscal 1998 and
1997, respectively. Other income in fiscal 1998 was due primarily to the gain on
a foreign currency exchange rate and to the sale of scrap materials. In fiscal
1997, the primary components were the result of a gain on the sale of a storage
facility, the sale of fully depreciated equipment and a finder's fee we earned,
offset by the write-off of other miscellaneous items.

Income Taxes The provision for income taxes was $180,000 and $54,000 in fiscal
1998 and 1997, respectively. This was comprised of $45,000 and $20,000 for
federal income tax and $135,000 and $34,000 for state income taxes in fiscal
1998 and 1997, respectively. Net operating loss carryforwards were available to
offset corporate federal income tax and we were generally subject only to the
alternative minimum tax. At such dates, we believed our tax benefits were
subject to a 100% valuation allowance as of July 31, 1998 and 1997 due to
earnings fluctuations inherent in our operations and recent operating losses.

Liquidity and Capital Resources

      Our cash and cash equivalents position increased by $3.2 million from $2.7
million at July 31, 1998 to $5.9 million at July 31, 1999. Restricted cash of
$22,000, which was securing standby letters of credit at July 31, 1998, was no
longer required at the end of fiscal 1999. In fiscal 1999, operating activities
provided net cash of $4.9 million, investing activities used net cash of $1.2
million and financing activities used net cash of $598,000. During fiscal 1999,
we acquired the assets and assumed certain liabilities of two businesses: a
mobile data communications services business and a wireless local loop business.
The total consideration for these acquisitions of approximately $978,000 was
financed by a cash payment of $200,000, a non-recourse note of $250,000 and the
issuance of restricted stock and warrants. As of July 31, 1999, one of these
acquisitions, the wireless local loop business, was classified as a discontinued
operation and certain adjustments were made and expenses accrued, as a result of
this decision.


                                       14
<PAGE>

      Accounts receivable as of July 31, 1999 decreased by $1.0 million from
July 31, 1998 to July 31, 1999 due primarily to the timing of the shipments and
subsequent collections. The allowance for doubtful accounts decreased by
$25,000. We review our allowance for doubtful accounts periodically and believe
it adequately reflects the collectibility of our receivables based on past
experience and our credit standards. Generally, foreign customers are required
to secure payment by an irrevocable letter of credit before an order is
accepted.

      Inventory increased by $1.3 million from July 31, 1998 to July 31, 1999
due primarily to the higher level of backlog of orders. We generally operate on
a job-order cost basis, that is, costs are incurred as work-in-process inventory
for specific contracts or jobs. Accordingly, inventory levels will vary as a
function of our order backlog. We do have some product lines which require a
more rapid delivery response to customers' requirements and require us to
provide for a level of "off-the-shelf" equipment inventory availability. The
only other general inventory that we maintain is for basic components which are
common to many of our products. Inventory reserves increased by $341,000.
Inventory reserves are reviewed on an ongoing basis and adjustments are made as
needed.

      Net intangible assets at July 31, 1999 of $1.6 million represent goodwill
as a result of our acquisition of a mobile data communications services business
and entry into that segment. The amortization period for this asset is 20 years.

      Accounts payable increased by $372,000 from July 31, 1998 to July 31,
1999, due primarily to the timing of the purchases and to the higher volume of
inventory purchased due to the increased level of sales and backlog.

      Accrued expenses and other current liabilities increased by $2.4 million
from July 31,1998 to July 31, 1999. This was due primarily to the increase in
customer advances and deposits and, to a lesser extent, to accrued wages and
benefits. Whenever possible, we require advance payments, deposits or
"milestone" payments on long-term contracts in order to provide working capital
while the contract is in process. Accrued wages and benefits are primarily a
function of the number of employees. At July 31,1999, we had 268 employees
compared to 216 employees at July 31,1998.

      During fiscal 1999, we made leasehold improvements and purchases of
machinery and equipment of $1.1 million, of which $136,000 was financed by
capital leases.

      All of our long-term debt consists of capital lease obligations. Principal
payments on long-term debt of $821,000 were made during fiscal 1999, resulting
in long-term debt, including the current portion, of $1.6 million.

      We have an $8.0 million secured credit facility from Republic National
Bank of New York. The line of credit, which is to be used for working capital
requirements, is for a term of one year and bears interest on borrowing of
90-day LIBOR plus 1.50 % (6.875% at July 31,1999). During fiscal 1999, we drew
advances in the aggregate of $850,000 which were totally repaid by July 31,
1999. The credit facility expires December 31, 1999. We have renewed and
received increases in this line of credit annually since 1996.

      We believe that our working capital position and available credit
facilities are sufficient to meet our cash requirements during the next year at
our current business levels. However, given the potential for receipt of large
orders under the U.S. Army contract, or the growth of our business beyond
expected levels, we may seek additional external financing.

Year 2000 Compliance

      Management has initiated a company-wide program and has developed a formal
plan of implementation to prepare for the Year 2000. This includes taking
actions designed to ensure that our information technology systems, products and
infrastructure are Year 2000 compliant and that its customers, suppliers and
service providers have taken similar action. With respect to Year 2000 internal
issues, we have evaluated our information technology systems, products,
equipment and other facilities systems, and management believes that all are
Year 2000 compliant. With respect to our external Year 2000 issues, we are
surveying our customers, suppliers and service providers primarily through
written correspondence. Despite the efforts to survey customers, suppliers and
service providers, management cannot be certain as to the actual Year 2000
readiness of these third parties. To the extent any of our suppliers or service
providers are not Year 2000 ready, we believe that we will be able to obtain
other


                                       15
<PAGE>

suppliers or service providers without a significant interruption to our
business. Based upon responses to our inquiries of third parties, we currently
believe we do not have a need for a contingency plan. Certain experts who have
studied the issue have published reports indicating that the Year 2000 problem
could be substantially more severe in developing economies than in the United
States. A significant amount of our sales are for customers in developing
countries.

      Our management currently believes that the costs related to our compliance
with the Year 2000 issue will not have a material adverse effect on our
consolidated financial position, results of operations or cash flows.

       ITEM 7A. QUANTATATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      The Company's earnings and cash flows are subject to fluctuations due to
changes in interest rates primarily from its investment of available cash
balances in money market funds. Under its current policies, the Company does not
use the interest rate derivative instruments to manage exposure to interest rate
changes.

                          Independent Auditors' Report

The Board of Directors and Stockholders
Comtech Telecommunications Corp.:

We have audited the consolidated financial statements of Comtech
Telecommunications Corp. and subsidiaries as listed in the accompanying index.
In connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedule II as listed in the accompanying
index. These consolidated financial statements and financial statement schedule
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements and financial
statement schedule 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
reasonably assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Comtech
Telecommunications Corp. and subsidiaries as of July 31, 1999 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended July 31, 1999 in conformity with generally accepted
accounting principles. Also in our opinion, the related financial statement
schedule II, when considered in relation to the basic consolidated financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

                   Notes to Consolidated Financial Statements

                             July 31, 1999 and 1998

(1)   Summary of Significant Accounting and Reporting Policies

      (a)   Principles of Consolidation

      The accompanying consolidated financial statements include the accounts
            of Comtech Telecommunications Corp. and its subsidiaries (the
            Company), all of which are wholly-owned. All significant
            intercompany balances and transactions have been eliminated in
            consolidation.

      (b)   Nature of Business

      We design, develop, produce and market sophisticated components and
            systems that are used by telecommunications and defense systems and
            service providers in a broad range of applications.

      The Company's business is highly competitive and characterized by rapid
            technological change. In addition, the number of potential customers
            for the Company's products is limited. The Company's growth and
            financial position depends, among other things, on its ability to
            keep pace with such changes and developments and to respond to the
            sophisticated requirements of an increasing variety of electronic
            equipment users. Many of the Company's competitors are substantially
            larger, have significantly greater financial, marketing and
            operating resources and broader product lines than does the Company.
            A significant technological breakthrough by others, including
            smaller competitors or new companies, could have a material adverse
            effect on the Company's business. In addition, certain of the
            Company's customers have technological capabilities in the Company's
            product areas and could choose to replace the Company's products
            with their own.

      International sales expose the Company to certain risks, including
            barriers to trade, fluctuations in foreign currency exchange rates
            (which may make the Company's products less price competitive),
            political and economic instability, availability of suitable export
            financing, export license requirements, tariff regulations, and
            other United States and foreign regulations that may apply to the
            export of the Company's products, as well as the generally greater
            difficulties of doing business abroad. The Company attempts to
            reduce the risk of doing business in foreign countries by seeking
            contracts denominated in U.S. dollars, advance payments and
            irrevocable letters of credit in its favor.

      (c)   Revenue Recognition

      Revenues on long-term, fixed price contracts are generally recorded based
            on the relationship of total costs incurred to date to total
            projected final costs or, alternatively, as deliveries are made.
            Revenue under cost reimbursement contracts are recorded as costs are
            incurred.

      Revenues on other contract orders are recognized under the units of
            delivery method. Under this method, revenues are recorded as units
            are delivered with the related cost of sales recognized on each
            shipment based upon a percentage of estimated final contract costs.
            Contract costs include material, direct labor, manufacturing
            overhead and other direct costs. Retainages and estimated earnings
            in excess of amounts billed on certain multi-year programs are
            reported as unbilled receivables.

                                                                     (Continued)


                                      F-8
<PAGE>

      Revenue not associated with long-term contracts are generally recognized
            when the earnings process is complete, generally upon shipment or
            customer acceptance.

      Provision for anticipated losses on uncompleted contracts is made in the
            period in which such losses are determined.

      (d)   Cash and Cash Equivalents

      Cash equivalents consist of highly liquid direct obligations of the U.S.
            government with a maturity at acquisition of three months or less.
            Cash equivalents of July 31, 1999 and 1998 amounted to $2,258,000
            and $1,991,000. These investments are carried at cost plus accrued
            interest, which approximates market. The Company had $22,000 of
            restricted cash securing letter of credit obligations with a
            financial institution at July 31, 1998.

      (e)   Statement of Cash Flows

      The Company acquired equipment financed by capital leases in the amounts
            of $136,000, $1,207,000 and $48,000 in 1999, 1998 and 1997,
            respectively.

      (f)   Inventories

      Work-in-process inventory reflects all accumulated production costs, which
            are comprised of direct production costs and overhead, reduced by
            amounts attributable to units delivered. These inventories are
            reduced to their estimated net realizable value by a charge to cost
            of sales in the period such excess costs are determined.

      Raw materials and components and work-in-process inventory are stated at
            the lower of cost or market, computed on the first-in, first-out
            (FIFO) method.

      (g)   Long-Lived Assets

      The Company's plant and equipment, which are recorded at cost, are
            depreciated or amortized over their estimated useful lives (building
            and improvements - 40 years, equipment - three to eight years) under
            the straight-line method. Capitalized values of properties under
            leases are amortized over the life of the lease or the estimated
            life of the asset, whichever is less. Intangible assets, consisting
            of goodwill resulting from acquisitions, is being amortized over
            twenty years. The Company reviews its long-lived assets for
            impairment whenever events or circumstances indicate that the
            carrying amount of an asset may not be recoverable. If the sum of
            the expected cash flows, undiscounted and without interest, is less
            than the carrying amount of the asset, an impairment loss is
            recognized as the amount by which the carrying amount of the asset
            exceeds its fair value.

      (h)   Other Assets

      Included in other assets at July 31, 1999 and 1998 is approximately
            $350,000 less accumulated amortization, which relates to an
            intellectual property rights agreement being amortized over the
            eight-year term of the agreement. At July 31, 1999 and 1998,
            accumulated amortization related to this purchased technology was
            approximately $232,000 and $190,000, respectively. The Company
            assesses the recoverability of the intangible asset by determining
            whether the amortization of purchased technology over its remaining
            life can be recovered through undiscounted future operating cash
            flows from product sales utilizing the technology.

      (i)   Research and Development Costs

      The Company charges research and development costs to operations as
            incurred, except in those cases in which such costs are reimbursable
            under customer-funded contracts. In fiscal 1999, 1998 and 1997, the
            Company was reimbursed by customers for such activities in the
            amount of $1,779,000, $356,000 and $436,000, respectively.

                                                                     (Continued)


                                      F-9
<PAGE>

      (j)   Income Taxes

      Income taxes are accounted for under the asset and liability method.
            Deferred tax assets and liabilities are recognized for the future
            tax consequences attributable to differences between the financial
            statement carrying amounts of existing assets and liabilities and
            their respective tax bases and operating loss and tax credit
            carryforwards. Deferred tax assets and liabilities are measured
            using the enacted tax rates expected to apply to taxable income in
            the years in which those temporary differences are expected to be
            recovered or settled. The effect on deferred tax assets and
            liabilities of a change in tax rates is recognized in income in the
            period that includes the enactment date.

      (k)   Earnings Per Share

      The Company calculates earnings per share ("EPS") in accordance with the
            Statement of Financial Accounting Standards ("SFAS") No. 128,
            "Earnings per Share". Basic EPS are computed based on the weighted
            average number of shares outstanding. Diluted EPS reflects the
            maximum dilution from potential common stock issuable pursuant to
            the exercise of stock options and warrants, if dilutive, outstanding
            during each period. All share and per share amounts have been
            restated to reflect a three-for-two stock split effective July 30,
            1999 (Note 9(e)).

      (l)   Financial Instruments

      Management of the Company believes that the book value of its monetary
            assets and liabilities approximates fair value as a result of the
            short-term nature of such assets and liabilities. Management further
            believes that the fair market value of long-term debt relating to
            capital leases does not differ materially from its carrying value.

      (m)   Use of Estimates

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

      (n)   Accounting for Stock-Based Compensation

      The Company records compensation expense for employee stock options only
            if the current market price of the underlying stock exceeds the
            exercise price on the date of the grant. The Company has elected not
            to implement the fair value based accounting method for employee
            stock options of SFAS No. 123, "Accounting for Stock-Based
            Compensation", but has elected to disclose the pro forma net income
            per share for employee stock option grants made beginning in fiscal
            1996 as if such method had been used to account for stock-based
            compensation cost as described in SFAS No. 123.

      (o)   Reporting Comprehensive Income

      The Company has adopted SFAS No. 130, "Reporting Comprehensive Income,"
            which requires companies to report all changes in equity during a
            period, except those resulting from investment by owners and
            distribution to owners, for the period in which they are recognized.
            Comprehensive income is the total of net income and all other
            nonowner changes in equity (or other comprehensive income) such as
            unrealized gains/losses on securities classified as
            available-for-sale, foreign currency translation adjustments and
            minimum pension liability adjustments.

      Comprehensive and other comprehensive income must be reported on the face
            of annual financial statements or in the case of interim reporting,
            the footnote approach may be utilized. The Company's operations did
            not give rise to items includible in comprehensive income which were
            not already included in net income. Accordingly, the Company's
            comprehensive income is the same as its net income for all periods
            presented.

      In December 1991, the Company and a partnership controlled by the
            Company's Chairman, Chief Executive Officer and President entered
            into an agreement in which the Company leases from the partnership
            its corporate headquarters and Melville production facility. The
            lease is for a ten-year period and provides for annual rentals of
            approximately $448,000 for fiscal 1999, subject to annual
            adjustments equal to the lesser of 5% or the change in the Consumer
            Price Index. For financial reporting purposes, the Company has
            capitalized this lease at inception in the amount of $2,450,000, net
            of deferred interest of $1,345,000. The outstanding balance at July
            31, 1999 and 1998 approximated $817,000 and $1,105,000,
            respectively.

      The Company provides for income taxes under the provisions of SFAS No.
            109, "Accounting for Income Taxes". SFAS 109 requires an asset and
            liability based approach in accounting for income taxes. In
            assessing the realizability of deferred tax assets and liabilities,
            management considers whether it is more likely than not that some
            portion or all of them will not be realized. At July 31, 1998 the
            Company had a 100% valuation allowance against these gross deferred
            tax assets. During fiscal 1999, the Company concluded that a full
            valuation allowance was no longer necessary given its estimates of
            future earnings, which include substantial long-term contracts
            entered into in the first and fourth quarters of fiscal 1999 and the
            expected timing of temporary difference reversals. Accordingly, the
            Company reduced the valuation allowance to $777,000 during fiscal
            1999 and recorded deferred tax assets of $4,575,000 of which
            $3,155,000 was recorded in the fourth quarter. The Company must
            generate approximately $13,500,000 of taxable income to fully
            utilize its deferred tax assets. Management believes it is more
            likely than not that the results of future operations will generate
            sufficient taxable income to realize the net deferred tax assets.

(9)   Stockholders' Equity

      (a)   Option and Warrant Plans and Agreements

      The Company has several option and warrant plans and agreements as
            follows:

      1982 Incentive Stock Option Plan - The 1982 Incentive Stock Option and
            Appreciation Plan provided for the granting to key employees and
            officers of incentive stock options to purchase up to 240,000 shares
            of the Company's common stock through September 29, 1992 at prices
            not less than the fair market value of such shares on the date the
            option is granted. The plan expired on September 29, 1992. Options
            granted to purchase an aggregate of 16,350 shares remain
            outstanding.

      1993 Incentive Stock Option Plan - The 1993 Incentive Stock Option Plan,
            as amended, provides for the granting to key employees and officers
            of incentive and non-qualified stock options to purchase up to
            1,042,500 shares of the Company's common stock at prices generally
            not less than the fair market value at the date of grant with the
            exception of anyone who, prior to the grant, owns more than 10% of
            the voting power, the exercise price cannot be less than 110% of the
            fair market value. In addition, it provides formula grants to
            non-employee members of the Board of Directors. The term of the
            options may be no more than ten years. However, for incentive stock
            options granted to any employee who, prior to the granting of the
            option, owns stock representing more than 10% of the voting power,
            the option term may be no more than five years. The plan expires in
            2002, unless terminated earlier by the Board of Directors under
            conditions specified in the plan. As of July 31, 1999, the Company
            had granted incentive stock options representing the right to
            purchase an aggregate of 1,029,015 shares at prices ranging between
            $1.50 - $7.50 per share, of which 69,600 options were canceled and
            888,045 are outstanding at July 31, 1999. To date, 71,370 shares
            have been exercised.

      Warrant Issued Pursuant to Acquisition of CMDC - As part of the asset
            purchase agreement for the acquisition of Mobile Datacom Corp. (see
            Note 12), which was incorporated into the Company as a wholly-owned
            subsidiary, Comtech Mobile Datacom Corp., the Company issued
            warrants to the owners and creditors to purchase 150,000 shares of
            the Company's common stock at an exercise price of $6.57. The
            warrants, which contain transferability restrictions, are
            exercisable for a period of five years commencing September 24,
            1998, and shares purchased through the exercise of these warrants
            contain voting restrictions. Due to the transferability and voting
            restrictions and other conditions, no value was ascribed to these
            warrants for purposes of determining the cost of the acquisition.

      (c)   Stock-Based Compensation Plans

      The Company has two stock option plans, the 1982 Incentive Stock Option
            and Appreciation Plan and the 1993 Incentive Stock Option Plan. The
            Company accounts for these plans under APB Opinion No. 25, under
            which no compensation cost has been recognized. Had compensation
            cost for these plans been determined consistent with SFAS No. 123,
            the Company's net income and income per share would have been
            reduced to the following pro forma amounts:

                                                1999          1998         1997
                                         -----------   -----------  -----------
Net income      As reported              $ 5,255,000     1,104,000      484,000
                Pro forma                $ 4,836,000       817,000      475,000

Net income
 per share      As reported  Basic       $      1.27          0.28         0.13
                             Diluted     $      1.15          0.27         0.12

                Pro forma    Basic       $      1.17          0.21         0.12
                             Diluted     $      1.06          0.19         0.12

      The full impact of calculating compensation cost for stock options under
            SFAS No. 123 is not reflected in the pro forma net income and net
            income per share amounts presented above because compensation cost
            is reflected over the option's vesting period and compensation cost
            for options granted prior to August 1, 1995 was not considered.

      The per share weighted-average fair value of stock options granted
            during 1999 and 1998 was $3.19 and $2.30, respectively, on the date
            of grant using the Black Scholes option-pricing model with the
            following weighted-average assumptions:

      1999 - expected dividend yield of 0%, risk-free interest rate of 5.86%,
            expected volatility of 69.5% and an expected option life of 10
            years.

      1998 - expected dividend yield of 0%, risk-free interest rate of 6%,
            expected volatility of 63.32% and an expected option life of 10
            years.

      1997 - expected dividend yield of 0%, risk-free interest rate of 6%,
            expected volatility of 64.49% and an expected option life of 10
            years.

      (d)   Restricted Common Stock

      In February 1994, a total of 180,000 (after effect of three-for-two
            stock split - see Note 9(e)) restricted shares of the Company's
            common stock were granted by the Board of Directors to the principal
            officers of one of the Company's operating units, Comtech
            Communications Corp, ("CCC"), at a cost of $.10 per share. The award
            relates to services to be provided over future years and, as a
            result, the stock awards are subject to certain restrictions which
            may be removed earlier upon CCC attaining certain business plan
            milestones, as provided in the agreement, but no later than ten
            years from the date of the award. The excess of market value over
            cost of the shares awarded of $633,000 was recorded as deferred
            compensation and is being amortized to expense over a ten-year
            period subject to the aforementioned accelerated provisions, if
            appropriate, as evaluated on an annual basis. The deferred
            compensation is reflected as a reduction of stockholders' equity in
            the accompanying consolidated balance sheet. During fiscal 1997,
            60,000 of such shares were forfeited due to the termination of an
            officer's employment prior to vesting.

      In October 1998, a total of 225,000 (after effect of three-for-two
            stock split - see Note 9(e)) restricted shares of the Companys'
            common stock were granted by the Board of Directors to the principal
            officers and employees of the Companys' new subsidiary, Comtech
            Mobile Datacom Corp.("CMDC"), at a cost of $.10 per share. The award
            relates to services to be provided over future years and, as a
            result, the stock awards are subject to certain restrictions which
            may be removed earlier upon CMDC attaining certain business plan
            milestones, as provided in the agreement, but no later than ten
            years from the date of the award. The excess of market value over
            cost of the


                                      F-16
<PAGE>

            shares awarded of $1,041,000 was recorded as deferred compensation
            and is being amortized to expense over a ten-year period subject to
            the aforementioned accelerated provisions, if appropriate, as
            evaluated on an annual basis. The deferred compensation is reflected
            as a reduction of stockholders' equity in the accompanying
            consolidated balance sheet as of July 31,1999.

      (d)   Stock Split

      On July 6, 1999, the Company's Board of Directors authorized a
            three-for-two stock split effected in the form of a 50% stock
            dividend payable July 30, 1999 to stockholders of record on July 16,
            1999. All share and per share amounts in the accompanying
            consolidated financial statements have been restated to reflect the
            stock split.

(10)  Segment and Principal Customer Information

      Effective July 31, 1999, the Company adopted SFAS No. 131,"Disclosures
            about Segments of an Enterprise and Related Information." Reportable
            operating segments are determined based on the Company's management
            approach. The management approach, as defined by SFAS No. 131, is
            based on the way that the chief operating decision-maker organizes
            the segments within an enterprise for making operating decisions and
            assessing performance. While the Company's results of operations are
            primarily reviewed on a consolidated basis, the chief operating
            decision-maker also manages the enterprise in four segments:

            (I)Telecommunications Transmission, (II) RF Microwave Amplifiers,
            (III) Mobile Data Communications Services and (IV) Wireless Local
            Loop, which is being discontinued. Telecommunications Transmission
            products include modems, frequency converters, satellite VSAT
            transceivers and antennas and over-the-horizon microwave
            communications products and systems. RF Microwave Amplifier products
            include high-power amplifier products that use the microwave and
            radio frequency spectrums. Mobile Data Communications Services
            include two-way messaging links between mobile platforms or remote
            sites and user headquarters using satellite, terrestrial microwave
            or Internet links. Corporate assets consist principally of cash,
            deferred tax assets and intercompany receivables. Corporate losses
            result from such corporate expenses as legal, accounting and
            executive. Sales between segments were negligible. Eliminations
            consist of intercompany balances.

      Sales to one customer in fiscal 1999 and to different customers in fiscal
            1998 and 1997 represented 27.0% and 12.2% and 10.2% of the
            consolidated net sales, respectively. Such sales were made from the
            Telecommunications Transmission business segment in 1999 and 1997,
            and from the RF Microwave Amplifier business segment in 1998.

      During fiscal 1999, 1998 and 1997, approximately 16%, 20% and 17%,
            respectively, of the Company's net sales resulted from contracts
            with the United States government and its agencies. Export sales
            comprised 60%, 46% and 57% of net sales in fiscal 1999, 1998 and
            1997, respectively. Export sales include sales to domestic companies
            for inclusion in products which will be sold to international
            customers.

(11)  Commitments and Contingencies

      (a)   Operating Leases

      The Company is obligated under noncancellable operating lease
            agreements. At July 31, 1999, the future minimum lease payments
            under operating leases are as follows:

                                 2000          $     355,000
                                 2001                355,000
                                 2002                193,000
                                 2003                196,000
                                               -------------
                                               $   1,099,000
                                               =============

      Lease expense charged to operations was $301,000, $140,000 and $123,000 in
            fiscal 1999, 1998 and 1997, respectively.

      (b)   United States Government Contracts

      Certain of the Company's contracts are subject to audit by applicable
            governmental agencies. Until such audits are completed, the ultimate
            profit on these contracts cannot be determined; however, it is
            management's belief that the final contract settlements will not
            have a material adverse effect on the Company's consolidated
            financial condition.

      (c)   Litigation

      The Company is subject to certain legal actions which arise out of the
            normal course of business. It is management's belief that the
            outcome of these actions will not have a material adverse effect on
            the Company's consolidated financial position.



                                      F-18
<PAGE>

      (d)   Employment Contract

      Mr. Kornberg, the Company's Chairman of the Board of Directors, Chief
            Executive Officer and President is employed pursuant to an agreement
            which was amended and restated in January 1998 which provides, among
            other things, for his employment until 2003 at a current basic
            compensation of $295,000 per annum plus such additional amounts, if
            any, as the Board of Directors may from time to time determine.

(12)  Acquisitions

      In the first quarter of fiscal 1999, the Company formed two
            subsidiaries, Comtech Mobile Datacom Corp. ("CMDC") and Comtech
            Wireless, Inc. ("CWI") to acquire the assets and assume certain
            liabilities of two businesses. The purchase price of the business
            acquired by CMDC amounted to $628,000 consisting of cash of
            $100,000, 150,000 shares of restricted common stock, valued at
            $528,000, and warrants to purchase 150,000 shares of common stock at
            an exercise price of $6.57 per share. The purchase price of the
            business acquired by CWI amounted to $350,000 consisting of $100,000
            of cash and a non-recourse note payable of $250,000. The assets
            acquired were inventories and equipment. Both acquisitions were
            accounted for as purchases whereby the assets and liabilities of the
            businesses acquired were consolidated with those of the Company from
            their respective acquisition dates. The excess of the purchase price
            over the fair value of the net assets of the business acquired by
            CMDC approximated $1,701,000 and is being amortized over a 20-year
            period. This amount is included in intangible assets in the
            accompanying consolidated balance sheet. Effective July 31, 1999,
            the operations of the business acquired by CWI are being
            discontinued (see Note 13). The pro forma effect of the acquisition
            of CMDC was not material to the results of operations for the years
            ended July 31,1999 and 1998.

(13)  Discontinued Operations

      Based upon CWI's disappointing fiscal 1999 results of operations and its
            uncertain future prospects, in September 1999, the Board of
            Directors approved a plan to liquidate CWI by January 31, 2000. The
            consolidated financial statements of the Company have been
            reclassified to reflect the effects of the Company's decision to
            account for the disposal of CWI as a discontinued operation.
            Accordingly, costs and expenses, assets and liabilities, and cash
            flows associated with CWI have been excluded from the respective
            captions in the accompanying consolidated balance sheet, statements
            of operations and statements of cash flows. Components of amounts
            included in the net liabilities of discontinued operations in the
            accompanying consolidated balance sheet are as follows:

                                                                   July 31, 1999
                                                                   -------------

            Inventory                                                $  293,000
            Provision for operating losses during phase-out period     (430,000)

                                                                     ----------
                                                                     $ (137,000)
                                                                     ==========

      The Company expects to liquidate the operations of CWI by January 31,
            2000 and has estimated a loss of $470,000 on disposal of CWI's
            assets and $430,000 for operating losses through January 31, 2000.
            CWI had no revenue in fiscal 1999 and expenses of $942,000.

(14)  Stockholder Rights Plan

      On December 15, 1998, the Company's Board of Directors approved the
            adoption of a stockholder rights plan in which one stock purchase
            right ("Right") was distributed as a dividend on each outstanding
            share of the Company's common stock to stockholders of record at the
            close of business on January 4, 1999. Under the plan, the Rights
            will be exercisable only if triggered by a person or group's
            acquisition of 15% or more of the Company's common stock. If
            triggered, each Right, other than Rights held by the acquiring
            person or group, would entitle its holder to purchase a specified
            number of the Company's common shares for 50% of


                                      F-19
<PAGE>

            their market value at that time. Unless a 15% acquisition has
            occurred, the Rights may be redeemed by the Company at any time
            prior to the termination date of the plan.

            This Right to purchase common stock at a discount will not be
            triggered by a person's or group's acquisition of 15% or more of the
            common stock pursuant to a tender or exchange offer which is for all
            outstanding shares at a price and on terms that Comtech's Board of
            Directors determines (prior to acquisition) to be adequate and in
            the best interest of the Company and its stockholders. The Rights
            will expire on December 15, 2008.

o     Fiscal year-end Cumulative CMDC Pre-Tax              One-sixth (1/6)
      Profits of $7,000,000 and fiscal year Net          of Shares purchased

         (c)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement,  but subject to satisfying the tax withholding requirements contained
in Subsection 4(d) hereof,  (i) all Restricted Shares shall become  Unrestricted
Shares upon  termination  of  Employee's  employment  with CMDC by reason of his
death,  total and permanent  disability  (as  determined in accordance  with the
policies and practices of Comtech),  normal  retirement  (at or after age 70 or,
with the consent of Comtech,  before age 70), or early  retirement  at Comtech's
request; and (ii) upon discharge of Employee by CMDC other than for cause (which
for this purpose shall mean Employee's willful misconduct,  dereliction of duty,
or conviction for a crime involving moral turpitude).

         (d) If, at the time any  Shares  become  Unrestricted  Shares,  Comtech
determines  that it has  withheld an amount  which is less than the  withholding
that may be required  pursuant to the Internal  Revenue Code or other applicable
law,  Employee shall forthwith pay to Comtech the amount of monies  necessary to
satisfy such withholding or equivalent  requirements.  Until the payment of such
monies or,  alternatively the execution and delivery by Employee of an agreement
satisfactory to Comtech in it sole discretion  providing for the payment of such
monies,  the Unrestricted  Shares shall not be released to Employee  pursuant to
the terms of the Escrow Agreement. If payment of such monies is not made or such
agreement is not entered into,  such  Unrestricted  Shares  shall,  at Comtech's
direction,  be sold by  Employee  to Comtech  for a purchase  price equal to the
purchase price per share provided in Section 2 hereof,  adjusted, as appropriate
for any subsequent stock-split, recapitalization or the like.

         (e) In the event of Employee's  termination of employment with CMDC for
any reason other than those  specified  in  Subsection  4(c) hereof  (including,
without  limitation,  any voluntary  termination of  employment)  all Restricted
Shares shall be sold by Employee to Comtech,  for the price and otherwise in the
manner provided in Subsection 4(d) hereof.

         5. Representations and Warranties of Employee

         Employee represents and warrants as follows:

         (a)  Assuming  that  Comtech  has  transferred  to  Employee  good  and
marketable  title to the Shares,  Employee has not taken any action or permitted
any action to occur,  nor will  employee take any action or permit any action to
occur,  that would  result in the Shares  becoming  subject to any claim,  lien,
pledge or encumbrance of any nature whatsoever.


                                       4

<PAGE>


         (b)  Employee  has full legal power and capacity to execute and deliver
this  Agreement,  and such execution and delivery and  Employee's  acceptance of
employment with CMDC  contemporaneously  with the execution and delivery of this
Agreement are not in violation of any other agreement,  instrument or obligation
to which  Employee is a party,  including,  without  limitation,  any employment
agreement or non-competition agreement of any kind whatsoever.

         (c) This Agreement  constitutes the legal, valid and binding obligation
of Employee.

         (d)  Employee  has not  employed  any broker or finder or incurred  any
liability for any brokerage  fees or  commissions or finders' fees in connection
with this Agreement.

         (e) Employee is acquiring the Shares for  investment  purposes only and
not with a view to distribution,  and  acknowledges  that he has been advised by
his counsel, and understands, that the Shares have not been registered under the
Securities Act of 1933, as amended,  and under the  securities  laws, may not be
sold or transferred unless registered under such Act or pursuant to an exemption
from such  registration  and that a  restrictive  legend to that effect shall be
placed on the certificate(s)  representing the Shares. Employee has further been
advised by his counsel  with  respect to making an election  pursuant to Section
83(b) of the Internal  Revenue Code and has chosen,  or will choose,  whether to
make such election as he deems appropriate.

         6. Representations and Warranties of Comtech

         Comtech represents and warrants as follows:

         (a)  Comtech is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of Delaware with full power and legal right
to execute and deliver this Agreement and perform its obligations hereunder.

         (b) The  execution  and  delivery of this  Agreement by Comtech and the
performance by it of its obligations  hereunder have been duly authorized by all
necessary  corporate  action  and do not  violate  the terms of any  outstanding
agreements to which it is a party. This Agreement  constitutes the legal,  valid
and binding obligation of Comtech.

         7. Certain Employment Matters

         (a) The purchase of Shares  hereunder shall not preclude  Employee from
being eligible to participate in any other plans, programs or benefits otherwise
available to employees of Comtech or its subsidiaries. Nothing in this Agreement
shall  be   construed  to   constitute   or  be  evidence  of  an  agreement  or
understanding,  express  or  implied,  on the part of  Comtech or CMDC to employ
Employee for any specific period of time.

         (b) In  consideration  of his  employment  with  CMDC  and the sale and
issuance of the Shares to him pursuant to this  Agreement,  Employee  shall not,
during the period he is employed by CMDC and for one year  thereafter  following
Employee's  voluntary  termination  of is  employment  by CMDC,  in any  manner,
directly or indirectly, engage anywhere in the United States in any

                                       5

<PAGE>


business which competes with the business in which CMDC or Comtech or any of its
other subsidiaries is engaged at any time during the period in which Employee is
employed  by CMDC,  and he shall  not,  directly  or  indirectly,  own,  manage,
operate, join, control or participate in the ownership, management, operation or
control of, or be employed by, or connected in any manner with any  corporation,
firm or business  that is so engaged;  provided,  however,  that nothing  herein
contained  shall  prohibit  Employee  from  owning  not  more  than  5%  of  the
outstanding stock of any publicly held corporation. If any restriction set forth
in this  Subsection  7(b) is  found  by a court  of  competent  jurisdiction  or
arbitrator to be unenforceable  because it extends for too long a period of time
or over too great a range of  activities  or in too broad a geographic  area, it
shall be interpreted  to extend only over the maximum  period of time,  range of
activities or geographic area as to which it may be enforceable.

         (c) Employee shall hold in a fiduciary capacity for the benefit of CMDC
and Comtech all confidential information, knowledge or data relating to CMDC and
Comtech  or any of its  other  subsidiaries,  and  their  respective  businesses
obtained  by  Employee  before or during the period in which he is  employed  by
CMDC.

         (d)  The  restrictions  contained  in  Subsections  (b) and (c) of this
Section 7 are necessary for the  protection of the business and goodwill of CMDC
and Comtech and are  considered  by Employee to be  reasonable  to such purpose.
Employee agrees that any breach of such  Subsections (b) and (c) will cause CMDC
and/or Comtech substantial and irreparable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, CMDC
and/or Comtech shall have the right to seek specific  performance and injunctive
relief.

         8. Liability of Comtech

         The  liability  of  Comtech  under  this  Agreement  is  limited to the
obligations  expressly set forth herein and nothing  herein  contained  shall be
construed to impose any  liability on Comtech in favor of Employee  with respect
to any loss,  cost or expense  which  Employee may incur or suffer in connection
with or arising out of this Agreement, including, without limitation, Employee's
purchase of the Shares.

         9. Voting Concerning Certain Corporate Matters

         (a) Employee  agrees to have  counted for purposes of a quorum,  and to
vote, all Restricted Shares (whether such vote shall be by written consent or by
vote,  in  person  or, if  requested  by  Comtech,  by  proxy,  at a meeting  of
shareholders of Comtech) for the election to Comtech's Board of Directors of the
nominees from time to time designated by the Board of Directors of Comtech.

         (b) To facilitate, and not in limitation of, the agreement contained in
Subsection 9(a) hereof,  Employee irrevocably appoints the Chairman of the Board
and the Secretary of Comtech,  and their  respective  successors in office,  and
each of them, with full power of substitution,  as the lawful proxy for Employee
as to all Restricted  Shares,  to vote all  Restricted  Shares which Employee is
entitled  to vote,  for and in the name,  place and  stead of  Employee,  at any
annual,  special  or other  meeting of the  holders of shares of Comtech  Common
Stock and at any adjournment thereof, or

                                       6

<PAGE>



pursuant to any  consent in lieu of a meeting,  for the  election  to  Comtech's
Board of  Directors  of the  nominees  designated  by the Board of  Directors of
Comtech.  The  foregoing  proxy is coupled  with an interest and  therefore  not
terminable by Employee without the consent of Comtech.

         10. Additional Restricted Shares.

         Employees  agrees that the term  "Restricted  Shares" shall include any
shares or other  securities  which he may receive or be entitled to receive as a
result of the ownership of the original  Restricted  Shares whether the same are
issued as a result of a share split, share dividend, recapitalization,  or other
subdivision or consolidation of shares effected without receipt of consideration
by Comtech or the  result of the merger or  consolidation  of Comtech or sale of
assets of Comtech.

         11. Binding Agreement

         This  Agreement  shall inure to the  benefit  of, and be binding  upon,
Comtech and its  successors  and assigns and  Employee  and his heirs,  personal
representatives, successors and assigns.

         12. Notices

         Any  notice,  request  or  other  communication  hereunder  shall be in
writing and shall be deemed to have been duly given if hand  delivered or mailed
by registered or certified mail, return receipt  requested,  addressed as herein
set forth,  or to such  other  address as may be  designated  by a notice  given
pursuant hereto,  which change of address notice shall be effective upon receipt

law,  Employee shall forthwith pay to Comtech the amount of monies  necessary to
satisfy such withholding or equivalent  requirements.  Until the payment of such
monies or,  alternatively the execution and delivery by Employee of an agreement
satisfactory to Comtech in it sole discretion  providing for the payment of such
monies,  the Unrestricted  Shares shall not be released to Employee  pursuant to
the terms of the Escrow Agreement. If payment of such monies is not made or such
agreement is not entered into,  such  Unrestricted  Shares  shall,  at Comtech's
direction,  be sold by  Employee  to Comtech  for a purchase  price equal to the
purchase price per share provided in Section 2 hereof,  adjusted, as appropriate
for any subsequent stock-split, recapitalization or the like.

          (e) In the event of Employee's termination of employment with CMDC for
any reason other than those  specified  in  Subsection  4(c) hereof  (including,
without  limitation,  any voluntary  termination of  employment)  all Restricted
Shares shall be sold by Employee to Comtech,  for the price and otherwise in the
manner provided in Subsection 4(d) hereof.

          5. Representations and Warranties of Employee

          Employee represents and warrants as follows:

          (a)  Assuming  that  Comtech  has  transferred  to  Employee  good and
marketable  title to the Shares,  Employee has not taken any action or permitted
any action to occur,  nor will  employee take any action or permit any action to
occur,  that would  result in the Shares  becoming  subject to any claim,  lien,
pledge or encumbrance of any nature whatsoever.



                                        4

<PAGE>



          (b)  Employee has full legal power and capacity to execute and deliver
this  Agreement,  and such execution and delivery and  Employee's  acceptance of
employment with CMDC  contemporaneously  with the execution and delivery of this
Agreement are not in violation of any other agreement,  instrument or obligation
to which  Employee is a party,  including,  without  limitation,  any employment
agreement or non-competition agreement of any kind whatsoever.

          (c) This Agreement constitutes the legal, valid and binding obligation
of Employee.

          (d)  Employee  has not  employed  any broker or finder or incurred any
liability for any brokerage  fees or  commissions or finders' fees in connection
with this Agreement.

          (e) Employee is acquiring the Shares for investment  purposes only and
not with a view to distribution,  and  acknowledges  that he has been advised by
his counsel, and understands, that the Shares have not been registered under the
Securities Act of 1933, as amended,  and under the  securities  laws, may not be
sold or transferred unless registered under such Act or pursuant to an exemption
from such  registration  and that a  restrictive  legend to that effect shall be
placed on the certificate(s)  representing the Shares. Employee has further been
advised by his counsel  with  respect to making an election  pursuant to Section
83(b) of the Internal  Revenue Code and has chosen,  or will choose,  whether to
make such election as he deems appropriate.

          6. Representations and Warranties of Comtech

          Comtech represents and warrants as follows:

          (a) Comtech is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of Delaware with full power and legal right
to execute and deliver this Agreement and perform its obligations hereunder.

          (b) The  execution  and delivery of this  Agreement by Comtech and the
performance by it of its obligations  hereunder have been duly authorized by all
necessary  corporate  action  and do not  violate  the terms of any  outstanding
agreements to which it is a party. This Agreement  constitutes the legal,  valid
and binding obligation of Comtech.

          7. Certain Employment Matters

          (a) The purchase of Shares hereunder shall not preclude  Employee from
being eligible to participate in any other plans, programs or benefits otherwise
available to employees of Comtech or its subsidiaries. Nothing in this Agreement
shall  be   construed  to   constitute   or  be  evidence  of  an  agreement  or
understanding,  express  or  implied,  on the part of  Comtech or CMDC to employ
Employee for any specific period of time.

          (b) In  consideration  of his  employment  with  CMDC and the sale and
issuance of the Shares to him pursuant to this  Agreement,  Employee  shall not,
during the period he is employed by CMDC and for one year  thereafter  following
Employee's  voluntary  termination  of is  employment  by CMDC,  in any  manner,
directly or indirectly, engage anywhere in the United States in any


                                        5

<PAGE>



business which competes with the business in which CMDC or Comtech or any of its
other subsidiaries is engaged at any time during the period in which Employee is
employed  by CMDC,  and he shall  not,  directly  or  indirectly,  own,  manage,
operate, join, control or participate in the ownership, management, operation or
control of, or be employed by, or connected in any manner with any  corporation,
firm or business  that is so engaged;  provided,  however,  that nothing  herein
contained  shall  prohibit  Employee  from  owning  not  more  than  5%  of  the
outstanding stock of any publicly held corporation. If any restriction set forth
in this  Subsection  7(b) is  found  by a court  of  competent  jurisdiction  or
arbitrator to be unenforceable  because it extends for too long a period of time
or over too great a range of  activities  or in too broad a geographic  area, it
shall be interpreted  to extend only over the maximum  period of time,  range of
activities or geographic area as to which it may be enforceable.

          (c)  Employee  shall hold in a fiduciary  capacity  for the benefit of
CMDC and Comtech all  confidential  information,  knowledge or data  relating to
CMDC  and  Comtech  or any of  its  other  subsidiaries,  and  their  respective
businesses  obtained  by  Employee  before or during  the  period in which he is
employed by CMDC.

          (d) The  restrictions  contained  in  Subsections  (b) and (c) of this
Section 7 are necessary for the  protection of the business and goodwill of CMDC
and Comtech and are  considered  by Employee to be  reasonable  to such purpose.
Employee agrees that any breach of such  Subsections (b) and (c) will cause CMDC
and/or Comtech substantial and irreparable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, CMDC
and/or Comtech shall have the right to seek specific  performance and injunctive
relief.

          8. Liability of Comtech

          The  liability  of  Comtech  under  this  Agreement  is limited to the
obligations  expressly set forth herein and nothing  herein  contained  shall be
construed to impose any  liability on Comtech in favor of Employee  with respect
to any loss,  cost or expense  which  Employee may incur or suffer in connection
with or arising out of this Agreement, including, without limitation, Employee's
purchase of the Shares.

          9. Voting Concerning Certain Corporate Matters

          (a) Employee  agrees to have counted for purposes of a quorum,  and to
vote, all Restricted Shares (whether such vote shall be by written consent or by
vote,  in  person  or, if  requested  by  Comtech,  by  proxy,  at a meeting  of
shareholders of Comtech) for the election to Comtech's Board of Directors of the
nominees from time to time designated by the Board of Directors of Comtech.

          (b) To facilitate,  and not in limitation of, the agreement  contained
in Subsection  9(a) hereof,  Employee  irrevocably  appoints the Chairman of the
Board and the Secretary of Comtech,  and their respective  successors in office,
and each of them,  with full  power of  substitution,  as the  lawful  proxy for
Employee  as to all  Restricted  Shares,  to vote all  Restricted  Shares  which
Employee is entitled to vote, for and in the name,  place and stead of Employee,
at any  annual,  special or other  meeting  of the  holders of shares of Comtech
Common Stock and at any adjournment thereof, or


                                        6

<PAGE>



pursuant to any  consent in lieu of a meeting,  for the  election  to  Comtech's
Board of  Directors  of the  nominees  designated  by the Board of  Directors of
Comtech.  The  foregoing  proxy is coupled  with an interest and  therefore  not
terminable by Employee without the consent of Comtech.

          10. Additional Restricted Shares.

          Employees agrees that the term  "Restricted  Shares" shall include any
shares or other  securities  which he may receive or be entitled to receive as a
result of the ownership of the original  Restricted  Shares whether the same are
issued as a result of a share split, share dividend, recapitalization,  or other
subdivision or consolidation of shares effected without receipt of consideration
by Comtech or the  result of the merger or  consolidation  of Comtech or sale of
assets of Comtech.

          11. Binding Agreement

          This  Agreement  shall inure to the  benefit of, and be binding  upon,
Comtech and its  successors  and assigns and  Employee  and his heirs,  personal
representatives, successors and assigns.

          12. Notices

          Any  notice,  request  or other  communication  hereunder  shall be in
writing and shall be deemed to have been duly given if hand  delivered or mailed
by registered or certified mail, return receipt  requested,  addressed as herein
set forth,  or to such  other  address as may be  designated  by a notice  given
pursuant hereto,  which change of address notice shall be effective upon receipt

       (c)    Notwithstanding  anything  to  the  contrary   contained   in this
Agreement,  but subject to satisfying the tax withholding requirements contained
in Subsection 4(d) hereof,  (i) all Restricted Shares shall become  Unrestricted
Shares upon  termination  of  Employee's  employment  with CMDC by reason of his
death,  total and permanent  disability  (as  determined in accordance  with the
policies and practices of Comtech),  normal  retirement  (at or after age 70 or,
with the consent of Comtech,  before age 70), or early  retirement  at Comtech's
request; and (ii) upon discharge of Employee by CMDC other than for cause (which
for this purpose shall mean Employee's willful misconduct,  dereliction of duty,
or conviction for a crime involving moral turpitude).

       (d)    If, at the time  any Shares  become  Unrestricted  Shares, Comtech
determines  that it has  withheld an amount  which is less than the  withholding
that may be required  pursuant to the Internal  Revenue Code or other applicable
law,  Employee shall forthwith pay to Comtech the amount of monies  necessary to
satisfy such withholding or equivalent  requirements.  Until the payment of such
monies or,  alternatively the execution and delivery by Employee of an agreement
satisfactory to Comtech in it sole discretion  providing for the payment of such
monies,  the Unrestricted  Shares shall not be released to Employee  pursuant to
the terms of the Escrow Agreement. If payment of such monies is not made or such
agreement is not entered into,  such  Unrestricted  Shares  shall,  at Comtech's
direction,  be sold by  Employee  to Comtech  for a purchase  price equal to the
purchase price per share provided in Section 2 hereof,  adjusted, as appropriate
for any subsequent stock-split, recapitalization or the like.

       (e)    In the  event of Employee's  termination  of employment  with CMDC
for any reason other than those specified in Subsection 4(c) hereof  (including,
without  limitation,  any voluntary  termination of  employment)  all Restricted
Shares shall be sold by Employee to Comtech,  for the price and otherwise in the
manner provided in Subsection 4(d) hereof.

       5.     Representations and Warranties of Employee

       Employee represents and warrants as follows:

       (a)    Assuming  that  Comtech  has  transferred  to  Employee  good  and
marketable  title to the Shares,  Employee has not taken any action or permitted
any action to occur,  nor will  employee take any action or permit any action to
occur,  that would  result in the Shares  becoming  subject to any claim,  lien,
pledge or encumbrance of any nature whatsoever.


                                       4

       (b)    Employee   has  full  legal  power  and  capacity  to  execute and
deliver  this  Agreement,   and  such  execution  and  delivery  and  Employee's
acceptance  of  employment  with CMDC  contemporaneously  with the execution and
delivery  of  this  Agreement  are  not in  violation  of any  other  agreement,
instrument  or  obligation  to which  Employee  is a party,  including,  without
limitation,  any employment  agreement or non-competition  agreement of any kind
whatsoever.

       (c)    This Agreement constitutes the legal, valid and binding obligation
of Employee.

       (d)    Employee  has not employed  any  broker or finder or incurred  any
liability for any brokerage  fees or  commissions or finders' fees in connection
with this Agreement.

not with a view to distribution,  and  acknowledges  that he has been advised by
his counsel, and understands, that the Shares have not been registered under the
Securities Act of 1933, as amended,  and under the  securities  laws, may not be
sold or transferred unless registered under such Act or pursuant to an exemption
from such  registration  and that a  restrictive  legend to that effect shall be
placed on the certificate(s)  representing the Shares. Employee has further been
advised by his counsel  with  respect to making an election  pursuant to Section
83(b) of the Internal  Revenue Code and has chosen,  or will choose,  whether to
make such election as he deems appropriate.

       6.     Representations and Warranties of Comtech

       Comtech represents and warrants as follows:

       (a)    Comtech  is a  corporation  duly  organized, existing  and in good
standing under the laws of the State of Delaware with full power and legal right
to execute and deliver this Agreement and perform its obligations hereunder.

       (b)    The  execution  and delivery of this  Agreement by Comtech and the
performance by it of its obligations  hereunder have been duly authorized by all
necessary  corporate  action  and do not  violate  the terms of any  outstanding
agreements to which it is a party. This Agreement  constitutes the legal,  valid
and binding obligation of Comtech.

       7.     Certain Employment Matters

       (a)    The purchase of Shares  hereunder shall not preclude Employee from
being eligible to participate in any other plans, programs or benefits otherwise
available to employees of Comtech or its subsidiaries. Nothing in this Agreement
shall  be   construed  to   constitute   or  be  evidence  of  an  agreement  or
understanding,  express  or  implied,  on the part of  Comtech or CMDC to employ
Employee for any specific period of time.

       (b)    In  consideration of his employment  with  CMDC  and the  sale and
issuance of the Shares to him pursuant to this  Agreement,  Employee  shall not,
during the period he is employed by CMDC and for one year  thereafter  following
Employee's  voluntary  termination  of is  employment  by CMDC,  in any  manner,
directly or indirectly, engage anywhere in the United States in any


                                       5

<PAGE>

business which competes with the business in which CMDC or Comtech or any of its
other subsidiaries is engaged at any time during the period in which Employee is
employed  by CMDC,  and he shall  not,  directly  or  indirectly,  own,  manage,
operate, join, control or participate in the ownership, management, operation or
control of, or be employed by, or connected in any manner with any  corporation,
firm or business  that is so engaged;  provided,  however,  that nothing  herein
contained  shall  prohibit  Employee  from  owning  not  more  than  5%  of  the
outstanding stock of any publicly held corporation. If any restriction set forth
in this  Subsection  7(b) is  found  by a court  of  competent  jurisdiction  or
arbitrator to be unenforceable  because it extends for too long a period of time
or over too great a range of  activities  or in too broad a geographic  area, it
shall be interpreted  to extend only over the maximum  period of time,  range of
activities or geographic area as to which it may be enforceable.

       (c)    Employee  shall  hold  in  a fiduciary capacity for the benefit of
CMDC and Comtech all  confidential  information,  knowledge or data  relating to
CMDC  and  Comtech  or any of  its  other  subsidiaries,  and  their  respective
businesses  obtained  by  Employee  before or during  the  period in which he is
employed by CMDC.

       (d)    The  restrictions  contained  in  Subsections (b)  and (c) of this
Section 7 are necessary for the  protection of the business and goodwill of CMDC
and Comtech and are  considered  by Employee to be  reasonable  to such purpose.
Employee agrees that any breach of such  Subsections (b) and (c) will cause CMDC
and/or Comtech substantial and irreparable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, CMDC
and/or Comtech shall have the right to seek specific  performance and injunctive
relief.

       8.      Liability of Comtech

       The  liability  of  Comtech  under  this  Agreement  is  limited  to  the
obligations  expressly set forth herein and nothing  herein  contained  shall be
construed to impose any  liability on Comtech in favor of Employee  with respect
to any loss,  cost or expense  which  Employee may incur or suffer in connection
with or arising out of this Agreement, including, without limitation, Employee's
purchase of the Shares.

       9.     Voting Concerning Certain Corporate Matters

       (a)    Employee  agrees to have  counted for purposes of a quorum, and to
vote, all Restricted Shares (whether such vote shall be by written consent or by
vote,  in  person  or, if  requested  by  Comtech,  by  proxy,  at a meeting  of
shareholders of Comtech) for the election to Comtech's Board of Directors of the
nominees from time to time designated by the Board of Directors of Comtech.

       (b)    To facilitate,  and not in limitation of, the agreement  contained
in Subsection  9(a) hereof,  Employee  irrevocably  appoints the Chairman of the
Board and the Secretary of Comtech,  and their respective  successors in office,
and each of them,  with full  power of  substitution,  as the  lawful  proxy for
Employee  as to all  Restricted  Shares,  to vote all  Restricted  Shares  which
Employee is entitled to vote, for and in the name,  place and stead of Employee,
at any  annual,  special or other  meeting  of the  holders of shares of Comtech
Common Stock and at any adjournment  thereof, or


                                        6

<PAGE>

pursuant to any  consent in lieu of a meeting,  for the  election  to  Comtech's
Board of  Directors  of the  nominees  designated  by the Board of  Directors of
Comtech.  The  foregoing  proxy is coupled  with an interest and  therefore  not
terminable by Employee without the consent of Comtech.

       10.    Additional Restricted Shares.

       Employees  agrees that the term  "Restricted  Shares"  shall  include any
shares or other  securities  which he may receive or be entitled to receive as a
result of the ownership of the original  Restricted  Shares whether the same are
issued as a result of a share split, share dividend, recapitalization,  or other
subdivision or consolidation of shares effected without receipt of consideration
by Comtech or the  result of the merger or  consolidation  of Comtech or sale of
assets of Comtech.

       11.    Binding Agreement

       This  Agreement  shall  inure to the  benefit  of, and be  binding  upon,
Comtech and its  successors  and assigns and  Employee  and his heirs,  personal
representatives, successors and assigns.

       12.    Notices

       Any notice, request or other communication  hereunder shall be in writing
and  shall be deemed to have  been  duly  given if hand  delivered  or mailed by
registered or certified mail, return receipt requested,  addressed as herein set
forth,  or to such other address as may be designated by a notice given pursuant
hereto, which change of address notice shall be effective upon receipt thereof.

Subsection 4(d) hereof, upon the first anniversary of the date hereof.

         (b) Subject to satisfying  the tax  withholding  requirements
contained in Subsection 4(d) hereof, the remaining  five-sixths of the

Shares on an accelerated  basis in the one-sixth  increments set forth
in the following  schedule  after the  Performance  Criteria set forth
therein are achieved:

                                                        Number of Shares

                                                          that become

         (c)  Notwithstanding   anything  to  the  contrary  contained  in  this
Agreement,  but subject to satisfying the tax withholding requirements contained
in Subsection 4(d) hereof,  (i) all Restricted Shares shall become  Unrestricted
Shares upon  termination  of  Employee's  employment  with CMDC by reason of his
death,  total and permanent  disability  (as  determined in accordance  with the
policies and practices of Comtech),  normal  retirement  (at or after age 70 or,
with the consent of Comtech,  before age 70), or early  retirement  at Comtech's
request; and (ii) upon discharge of Employee by CMDC other than for cause (which
for this purpose shall mean Employee's willful misconduct,  dereliction of duty,
or conviction for a crime involving moral turpitude).

         (d) If, at the time any  Shares  become  Unrestricted  Shares,  Comtech
determines  that it has  withheld an amount  which is less than the  withholding
that may be required  pursuant to the Internal  Revenue Code or other applicable
law,  Employee shall forthwith pay to Comtech the amount of monies  necessary to
satisfy such withholding or equivalent  requirements.  Until the payment of such
monies or,  alternatively the execution and delivery by Employee of an agreement
satisfactory to Comtech in it sole discretion  providing for the payment of such
monies,  the Unrestricted  Shares shall not be released to Employee  pursuant to
the terms of the Escrow Agreement. If payment of such monies is not made or such
agreement is not entered into,  such  Unrestricted  Shares  shall,  at Comtech's
direction,  be sold by  Employee  to Comtech  for a purchase  price equal to the
purchase price per share provided in Section 2 hereof,  adjusted, as appropriate
for any subsequent stock-split, recapitalization or the like.

         (e) In the event of Employee's  termination of employment with CMDC for
any reason other than those  specified  in  Subsection  4(c) hereof  (including,
without  limitation,  any voluntary  termination of  employment)  all Restricted
Shares shall be sold by Employee to Comtech,  for the price and otherwise in the
manner provided in Subsection 4(d) hereof.

         5. Representations and Warranties of Employee

         Employee represents and warrants as follows:

         (a)  Assuming  that  Comtech  has  transferred  to  Employee  good  and
marketable  title to the Shares,  Employee has not taken any action or permitted
any action to occur,  nor will  employee take any action or permit any action to
occur,  that would  result in the Shares  becoming  subject to any claim,  lien,
pledge or encumbrance of any nature whatsoever.

                                       4

<PAGE>



         (b)  Employee  has full legal power and capacity to execute and deliver
this  Agreement,  and such execution and delivery and  Employee's  acceptance of
employment with CMDC  contemporaneously  with the execution and delivery of this
Agreement are not in violation of any other agreement,  instrument or obligation
to which  Employee is a party,  including,  without  limitation,  any employment
agreement or non-competition agreement of any kind whatsoever.

         (c) This Agreement  constitutes the legal, valid and binding obligation
of Employee.

         (d)  Employee  has not  employed  any broker or finder or incurred  any
liability for any brokerage  fees or  commissions or finders' fees in connection
with this Agreement.

         (e) Employee is acquiring the Shares for  investment  purposes only and
not with a view to distribution,  and  acknowledges  that he has been advised by
his counsel, and understands, that the Shares have not been registered under the
Securities Act of 1933, as amended,  and under the  securities  laws, may not be
sold or transferred unless registered under such Act or pursuant to an exemption
from such  registration  and that a  restrictive  legend to that effect shall be
placed on the certificate(s)  representing the Shares. Employee has further been
advised by his counsel  with  respect to making an election  pursuant to Section
83(b) of the Internal  Revenue Code and has chosen,  or will choose,  whether to
make such election as he deems appropriate.

         6. Representations and Warranties of Comtech

         Comtech represents and warrants as follows:

         (a)  Comtech is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of Delaware with full power and legal right
to execute and deliver this Agreement and perform its obligations hereunder.

         (b) The  execution  and  delivery of this  Agreement by Comtech and the
performance by it of its obligations  hereunder have been duly authorized by all
necessary  corporate  action  and do not  violate  the terms of any  outstanding
agreements to which it is a party. This Agreement  constitutes the legal,  valid
and binding obligation of Comtech.

         7. Certain Employment Matters

         (a) The purchase of Shares  hereunder shall not preclude  Employee from
being eligible to participate in any other plans, programs or benefits otherwise
available to employees of Comtech or its subsidiaries. Nothing in this Agreement
shall  be   construed  to   constitute   or  be  evidence  of  an  agreement  or
understanding,  express  or  implied,  on the part of  Comtech or CMDC to employ
Employee for any specific period of time.

         (b) In  consideration  of his  employment  with  CMDC  and the sale and
issuance of the Shares to him pursuant to this  Agreement,  Employee  shall not,
during the period he is employed by CMDC and for one year  thereafter  following
Employee's  voluntary  termination  of is  employment  by CMDC,  in any  manner,
directly or indirectly, engage anywhere in the United States in any

                                       5

<PAGE>
business which competes with the business in which CMDC or Comtech or any of its
other subsidiaries is engaged at any time during the period in which Employee is
employed  by CMDC,  and he shall  not,  directly  or  indirectly,  own,  manage,
operate, join, control or participate in the ownership, management, operation or
control of, or be employed by, or connected in any manner with any  corporation,
firm or business  that is so engaged;  provided,  however,  that nothing  herein
contained  shall  prohibit  Employee  from  owning  not  more  than  5%  of  the
outstanding stock of any publicly held corporation. If any restriction set forth
in this  Subsection  7(b) is  found  by a court  of  competent  jurisdiction  or
arbitrator to be unenforceable  because it extends for too long a period of time
or over too great a range of  activities  or in too broad a geographic  area, it
shall be interpreted  to extend only over the maximum  period of time,  range of
activities or geographic area as to which it may be enforceable.

         (c) Employee shall hold in a fiduciary capacity for the benefit of CMDC
and Comtech all confidential information, knowledge or data relating to CMDC and
Comtech  or any of its  other  subsidiaries,  and  their  respective  businesses
obtained  by  Employee  before or during the period in which he is  employed  by
CMDC.

         (d)  The  restrictions  contained  in  Subsections  (b) and (c) of this
Section 7 are necessary for the  protection of the business and goodwill of CMDC
and Comtech and are  considered  by Employee to be  reasonable  to such purpose.
Employee agrees that any breach of such  Subsections (b) and (c) will cause CMDC
and/or Comtech substantial and irreparable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, CMDC
and/or Comtech shall have the right to seek specific  performance and injunctive
relief.

         8. Liability of Comtech

         The  liability  of  Comtech  under  this  Agreement  is  limited to the
obligations  expressly set forth herein and nothing  herein  contained  shall be
construed to impose any  liability on Comtech in favor of Employee  with respect
to any loss,  cost or expense  which  Employee may incur or suffer in connection
with or arising out of this Agreement, including, without limitation, Employee's
purchase of the Shares.

         9. Voting Concerning Certain Corporate Matters

         (a) Employee  agrees to have  counted for purposes of a quorum,  and to
vote, all Restricted Shares (whether such vote shall be by written consent or by
vote,  in  person  or, if  requested  by  Comtech,  by  proxy,  at a meeting  of
shareholders of Comtech) for the election to Comtech's Board of Directors of the
nominees from time to time designated by the Board of Directors of Comtech.

         (b) To facilitate, and not in limitation of, the agreement contained in
Subsection 9(a) hereof,  Employee irrevocably appoints the Chairman of the Board
and the Secretary of Comtech,  and their  respective  successors in office,  and
each of them, with full power of substitution,  as the lawful proxy for Employee
as to all Restricted  Shares,  to vote all  Restricted  Shares which Employee is
entitled  to vote,  for and in the name,  place and  stead of  Employee,  at any
annual,  special  or other  meeting of the  holders of shares of Comtech  Common
Stock and at any adjournment thereof, or

                                       6

<PAGE>


pursuant to any  consent in lieu of a meeting,  for the  election  to  Comtech's
Board of  Directors  of the  nominees  designated  by the Board of  Directors of
Comtech.  The  foregoing  proxy is coupled  with an interest and  therefore  not
terminable by Employee without the consent of Comtech.

         10. Additional Restricted Shares.

         Employees  agrees that the term  "Restricted  Shares" shall include any
shares or other  securities  which he may receive or be entitled to receive as a
result of the ownership of the original  Restricted  Shares whether the same are

subdivision or consolidation of shares effected without receipt of consideration
by Comtech or the  result of the merger or  consolidation  of Comtech or sale of
assets of Comtech.

         11. Binding Agreement

         This  Agreement  shall inure to the  benefit  of, and be binding  upon,

                                                        that become

         (c)  Notwithstanding   anything  to  the  contrary  contained  in  this

Shares upon  termination  of  Employee's  employment  with CMDC by reason of his
death,  total and permanent  disability  (as  determined in accordance  with the
policies and practices of Comtech),  normal  retirement  (at or after age 65 or,
with the consent of Comtech,  before age 65), or early  retirement  at Comtech's
request; and (ii) upon discharge of Employee by CMDC other than for cause (which
for this purpose shall mean Employee's willful misconduct,  dereliction of duty,
or conviction for a crime involving moral turpitude).

          (d) If, at the time any Shares  become  Unrestricted  Shares,  Comtech
determines  that it has  withheld an amount  which is less than the  withholding
that may be required  pursuant to the Internal  Revenue Code or other applicable
law,  Employee shall forthwith pay to Comtech the amount of monies  necessary to
satisfy such withholding or equivalent  requirements.  Until the payment of such
monies or,  alternatively the execution and delivery by Employee of an agreement
satisfactory to Comtech in its sole discretion providing for the payment of such
monies,  the Unrestricted  Shares shall not be released to Employee  pursuant to
the terms of the Escrow Agreement. If payment of such monies is not made or such
agreement is not entered into,  such  Unrestricted  Shares  shall,  at Comtech's
direction,  be sold by  Employee  to Comtech  for a purchase  price equal to the
purchase price per share provided in Section 2 hereof,  adjusted, as appropriate
for any subsequent stock-split, recapitalization or the like.

         (e) In the event of Employee's  termination of employment with CMDC for
any reason other than those  specified  in  Subsection  4(c) hereof  (including,
without  limitation,  any voluntary  termination of  employment)  all Restricted
Shares shall be sold by Employee to Comtech,  for the price and otherwise in the
manner provided in Subsection 4(d) hereof.

         5. Representations and Warranties of Employee

         Employee represents and warrants as follows:

         (a)  Assuming  that  Comtech  has  transferred  to  Employee  good  and
marketable  title to the Shares,  Employee has not taken any action or permitted
any action to occur,  nor will  employee

                                       4

<PAGE>
take any action or permit any action to occur,  that would  result in the Shares
becoming  subject  to any  claim,  lien,  pledge or  encumbrance  of any  nature
whatsoever.

         (b)  Employee  has full legal power and capacity to execute and deliver
this  Agreement,  and such execution and delivery and  Employee's  acceptance of
employment with CMDC  contemporaneously  with the execution and delivery of this
Agreement are not in violation of any other agreement,  instrument or obligation
to which  Employee is a party,  including,  without  limitation,  any employment
agreement or non-competition agreement of any kind whatsoever.

         (c) This Agreement  constitutes the legal, valid and binding obligation
of Employee.

         (d)  Employee  has not  employed  any broker or finder or incurred  any
liability for any brokerage  fees or  commissions or finders' fees in connection
with this Agreement.

         (e) Employee is acquiring the Shares for  investment  purposes only and
not with a view to distribution,  and  acknowledges  that he has been advised by
his counsel, and understands, that the Shares have not been registered under the
Securities Act of 1933, as amended,  and under the  securities  laws, may not be
sold or transferred unless registered under such Act or pursuant to an exemption
from such  registration  and that a  restrictive  legend to that effect shall be
placed on the certificate(s)  representing the Shares. Employee has further been
advised by his counsel  with  respect to making an election  pursuant to Section
83(b) of the Internal  Revenue Code and has chosen,  or will choose,  whether to
make such election as he deems appropriate.

         6. Representations and Warranties of Comtech

         Comtech represents and warrants as follows:

         (a)  Comtech is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of Delaware with full power and legal right
to execute and deliver this Agreement and perform its obligations hereunder.

         (b) The  execution  and  delivery of this  Agreement by Comtech and the
performance by it of its obligations  hereunder have been duly authorized by all
necessary  corporate  action  and do not  violate  the terms of any  outstanding
agreements to which it is a party. This Agreement  constitutes the legal,  valid
and binding obligation of Comtech.

         7. Certain Employment Matters

         (a) The purchase of Shares  hereunder shall not preclude  Employee from
being eligible to participate in any other plans, programs or benefits otherwise
available to employees of Comtech or its subsidiaries. Nothing in this Agreement
shall  be   construed  to   constitute   or  be  evidence  of  an  agreement  or
understanding,  express  or  implied,  on the part of  Comtech or CMDC to employ
Employee for any specific period of time.


                                       5

<PAGE>

          (b) In  consideration  of his  employment  with  CMDC and the sale and
issuance of the Shares to him pursuant to this  Agreement,  Employee  shall not,
during the period he is employed by CMDC and for one year  thereafter  following
Employee's  voluntary  termination  of his  employment  by CMDC,  in any manner,
directly or  indirectly,  engage  anywhere in the United  States in any business
which  competes  with the  business in which CMDC or Comtech or any of its other
subsidiaries  is engaged at any time  during  the  period in which  Employee  is
employed  by CMDC,  and he shall  not,  directly  or  indirectly,  own,  manage,
operate, join, control or participate in the ownership, management, operation or
control of, or be employed by, or connected in any manner with any  corporation,
firm or business  that is so engaged;  provided,  however,  that nothing  herein
contained  shall  prohibit  Employee  from  owning  not  more  than  5%  of  the
outstanding stock of any publicly held corporation. If any restriction set forth
in this  Subsection  7(b) is  found  by a court  of  competent  jurisdiction  or
arbitrator to be unenforceable  because it extends for too long a period of time
or over too great a range of  activities  or in too broad a geographic  area, it
shall be interpreted  to extend only over the maximum  period of time,  range of
activities or geographic area as to which it may be enforceable.

         (c) Employee shall hold in a fiduciary capacity for the benefit of CMDC
and Comtech all confidential information, knowledge or data relating to CMDC and
Comtech  or any of its  other  subsidiaries,  and  their  respective  businesses
obtained  by  Employee  before or during the period in which he is  employed  by
CMDC.

         (d)  The  restrictions  contained  in  Subsections  (b) and (c) of this
Section 7 are necessary for the  protection of the business and goodwill of CMDC
and Comtech and are  considered  by Employee to be  reasonable  to such purpose.
Employee agrees that any breach of such  Subsections (b) and (c) will cause CMDC
and/or Comtech substantial and irreparable damage and therefore, in the event of
any such breach, in addition to such other remedies which may be available, CMDC
and/or Comtech shall have the right to seek specific  performance and injunctive
relief.

         8. Liability of Comtech

         The  liability  of  Comtech  under  this  Agreement  is  limited to the
obligations  expressly set forth herein and nothing  herein  contained  shall be
construed to impose any  liability on Comtech in favor of Employee  with respect
to any loss,  cost or expense  which  Employee may incur or suffer in connection
with or arising out of this Agreement, including, without limitation, Employee's
purchase of the Shares.

         9. Voting Concerning Certain Corporate Matters

         (a) Employee  agrees to have  counted for purposes of a quorum,  and to
vote, all Restricted Shares (whether such vote shall be by written consent or by
vote,  in  person  or, if  requested  by  Comtech,  by  proxy,  at a meeting  of
shareholders of Comtech) for the election to Comtech's Board of Directors of the
nominees from time to time designated by the Board of Directors of Comtech.

         (b) To facilitate, and not in limitation of, the agreement contained in
Subsection 9(a) hereof,  Employee irrevocably appoints the Chairman of the Board
and the Secretary of Comtech, and
                                       6
<PAGE>
their  respective  successors  in office,  and each of them,  with full power of
substitution,  as the lawful proxy for Employee as to all Restricted  Shares, to
vote all  Restricted  Shares which  Employee is entitled to vote, for and in the
name,  place and stead of Employee,  at any annual,  special or other meeting of
the holders of shares of Comtech Common Stock and at any adjournment thereof, or
pursuant to any  consent in lieu of a meeting,  for the  election  to  Comtech's
Board of  Directors  of the  nominees  designated  by the Board of  Directors of
Comtech.  The  foregoing  proxy is coupled  with an interest and  therefore  not
terminable by Employee without the consent of Comtech.

         10. Additional Restricted Shares.

         Employees  agrees that the term  "Restricted  Shares" shall include any
shares or other  securities  which he may receive or be entitled to receive as a
result of the ownership of the original  Restricted  Shares whether the same are
issued as a result of a share split, share dividend, recapitalization,  or other
subdivision or consolidation of shares effected without receipt of consideration
by Comtech or the  result of the merger or  consolidation  of Comtech or sale of
assets of Comtech.

Government, will not constitute grounds for excusable delay by the contractor in
the performance of the contract nor will it justify or excuse the contractor
defaulting the performance of this contract; and such withdrawal will not serve

withdrawal is made for the reasons stated in subparagraph h above. Under no
circumstances will the withdrawal of such status or privileges be considered or

                             Statement of Objectives
                                     for the
                         Movement Tracking System (MTS)

1.       Program Goals.

The MTS is a world-wide, data communications capability for locating and
managing the movement of logistics and combat support vehicles. MTS will provide
in-transit visibility and velocity management of logistics and other Army combat
support assets anywhere from the sustaining base to the theater of operations.
MTS will be used to support missions throughout the full range of military
operations from peacetime to war. MTS will provide commanders with near
real-time data for location and status of logistics and combat support movement.
MTS will provide key capabilities to enable and enhance in-transit visibility
and velocity management such as the ability to reroute supplies due to changing
priorities, helping avoid hazards, and maintaining updated unit status. The MTS
capability will improve the efficiency and the effectiveness of distribution of
resources and assets.

2.       Program Objectives.

The Army will field an effective capability in response to the MTS mission needs
statement and MTS Operational Requirements Document (ORD). The MTS capability
will be consistent with the Army Force and Combat Service Support initiatives.
The Army recognizes that the key technologies required for MTS are available as
commercial or non-developmental items. However, the commercial satellite
communication services are not as prevalent and may be characterized as emerging
and not stable in terms of capability and service availability on a world-wide
basis. The Army recognizes that the acquisition and fielding of the MTS must be
accomplished at the same time that necessary technology and services are
advancing. Therefore, the Army will acquire the MTS with an initial set of
capabilities and provisions for Pre-Planned Product Improvements (P3I),
technology insertion, and technology additions consistent with the baseline
requirements and subsequent requirements of the ORD.

The MTS program is an integration program expected to leverage commercial items,
non-developmental items, and commercial communication services. MTS will
incorporate elements such as Global Positioning System (GPS), geographic
information system (GIS) mapping technologies, automatic identification
technologies (AIT), Information Security (INFOSEC), and encryption techniques,
Communications Security (COMSEC), and commercial satellite services.

In order to provide a baseline capability in the short term, the MTS will be
procured with a set of initial capabilities followed by P3I, technology
insertion, and technology additions. A key objective is to develop a system
architecture capable of accommodating system evolution without redesign. The
initial requirements must provide a significant, identifiable operational
capability and be supportable in the Army operational environment.

Another key objective is to provide the necessary software and hardware
modularity in the system design so that system elements can be separated from
the others for specialized upgrades. P3I, technology insertion, and technology
additions will provide incremental upgrades that will incorporate additional
functionality as stated in the MTS technical specifications. P3I,

technology insertion, and technology additions will also be utilized to
incorporate additional services and technology improvements to include access to
multiple satellite service providers. This approach will allow the program to
achieve overall capability through fielding and support of incremental upgrades
to the baseline operational capability.

3.       System/contract management

A Government/Contractor Integrated Product Team (IPT) will be established to
provide assistance, oversight, and review as the MTS proceeds through its
acquisition lifecycle. The EPT will execute the program using a plan and
schedule that will be developed after contract award.

4.       Specific Objectives

Provide world-wide MTS operational capability; articulate a stable system design
and architecture that provides for system evolution.

5.       System Design and Integration

Provide a modular software and hardware system design with an upgrade path for
system evolution.

Maximize use of commercial, non-developmental items, and open systems. Provide
capability that satisfies Information Security (INFOSEC) requirements for
sensitive but unclassified data as specified in MTS technical specifications,
use current robust industry encryption standards, and plan for cost-effective
future encryption improvements.

Provide necessary interfaces as specified in MTS technical specifications.

Perform total system integration (total system integration responsibility) prior
to delivery. All operating and system support software will be loaded. All
components will be integrated, configured, tested, and each equipment set will
be made operational.

6.       Validation Demonstration and Deployment

Conduct a Government-witnessed demonstration to validate that the system is
capable of performing as claimed in the winning proposal. The demonstration will
be scheduled in accordance with the MTS contract requirements. Deliver equipment
in accordance with MTS contract requirements.

7.       Operations and Support

Develop operations training and maintenance training.

Provide responsive, customer focused, full-service assistance program as
described in the MTS SOW/specification. This will include a problem report and
tracking process, telephonic trouble shooting assistance and problem resolution,
and feedback.

Provide an order processing and tracking information service for delivery/task
orders via email, World Wide Web or satellite messaging.

8.       System Evolution and P3I.

Design the MTS using highly modular elements allowing easy upgrade and system
evolution to include future access to multiple satellite service providers.

Conduct operational evaluation and pre-planned product improvements resulting in
delivery of objective requirements.

9.       System Cost.

Minimize cost of upgrades to objective requirements.

Minimize recurring unit cost of handheld, mobile, and control stations.

Minimize system life cycle costs.

1.     PURPOSE

The purpose of this procurement is to provide GPS, commercial computer
equipment; system support software; installation kits (A-Kit), air time,
associated documentation and reports; integration; maintenance; and technical
support services and services to provide a world-wide two-way data
communications and geo-location capability between mobile units (Handheld Mobile
Unit [V1] and Vehicle Mounted Mobile Unit [V2], also called B-Kits) and
designated control points (Control Stations). To the extent practical, the
equipment shall represent state-of-the-art technology. MTS will support
military operations on a world-wide basis in peacetime, peacekeeping and wartime
operations. MTS system components shall be capable of operating without the use
of direct telephone (land line or cellular) connections or LAN/WAN/INTERNET
direct connectivity.

2.     SCOPE

The equipment and services shall support the MTS program and operate in an open
systems environment on a world-wide basis. This environment requires solutions
that are compliant with open systems standards defined in the Department of Army
Joint Technical Architecture - Army (JTA-A). As part of the technical support
services provided under this contract, the Contractor may perform engineering
studies, technical services, develop device drivers to facilitate the passing of
data to an open systems environment compliant with the JTA-A and interfaces, and
develop A-Kits to facilitate vehicle integration.

The U.S. Army, other U.S. Armed Services, Department of Defense (DoD) Agencies,
other U.S. Federal Government Agencies, and foreign allied military services
shall be authorized to order from this contract.

3.     OPERATIONAL ENVIRONMENT

The Control Station will be operated in a fixed, heated/cooled environment
(operation center, etc.), but is required to be transportable and capable of
being interfaced to a LAN, and wide area network (WAN) for subsequent passing of
data. No dedicated power generation equipment is required. The Control Station
equipment requires standard 110-volt (CONUS) or 220-volt (OCONUS) 50/60 Hz
commercial power. Devices to protect against power surges (e.g., surge
suppressers) are required in CONUS and OCONUS. The Control Station is also
required to operate from battery power. The V1 and V2 units will be operated in
a mobile environment inside a vehicle. V1 units require battery power and an
additional connection for operation from vehicle power. V2 units, mounted in a
vehicle, require power from the vehicle only when the engine is running. The V2
shall be capable of operating from standard 110-volt (CONUS) or 220-volt
(OCONUS) 50/60 Hz commercial power.

Classification Specification, at Part III, Attachment III.b of the contract. The
Contractor shall not claim lack of security clearances as a reason for
non-compliance. The specific security access requirements will be set forth in
each respective delivery/task order.

b. As necessary for performance on this contract, the Government will provide
assistance to the Contractor in gaining access to Government facilities,
including controlled access areas.

6.9    USAGE TIME/AIR TIME

a. It is anticipated that the equipment proposed will require access to a
commercial communications provider. All costs for such usage shall be at a fixed
price for continuous unlimited usage on a daily, continuous 24 hour period,
basis, i.e. $X/per day/per unit, unlimited use. Daily unlimited use shall work
this way. A day of unlimited use shall be charged against a specific serialized
unit once that unit sends a message, or other traffic on that day, then within
that same 24 hour period that specific unit shall be afforded complete unlimited
access. No other notification to the contractor shall be required other than to
send a message. For these purposes, the sending of an acknowledgment "ACK" to a
received message shall also constitute activation of that days air time on and
for that unit. Usage of days of air time may not be continuous, but shall be
tracked by the contractor to inform the user, via the World-Wide Web Site, of
how many days of usage are remaining.

b. The contractor shall include a minimum 400 days of unlimited usage air time
in the price of both mobile units (V1 and V2) and Control Station. The 400 days
included with the units are required to be used within a maximum period of eight
years from contract award. Additional days of air time shall be separately
priced. All air time provided with the equipment, for equipment purchased on the
same date, shall be for the same duration. Availability of connection to a
commercial communications provider shall commence upon Government acceptance of
the system, with the 400 days ready for use. The charging or decrementing of
days used shall commence once a specific unit is activated with a message being
sent. The contractor shall have an accounting system that tracks usage time/air
time and allows the Government to obtain records of this usage by accessing the
contractor established WEB page (CLIN x018), with a method provided to allow a
user to query a specific unit to obtain the number of prepaid days of unlimited
use remaining. All MTS units which have reached 75% of the initial 400 days of
usage time/air time or subsequently purchased air time shall also be identified
in the database.

c. The contractor shall also provide monthly notification when 75% of the
initial 400 days or any subsequently purchased usage time/air time has been
expended for any of the MTS units. This list shall be included in the monthly
Project Status Report submitted under CLIN 0016.

d. The Government also has the option of purchasing MTS units and usage time/air
time in groups/pools of units. In these cases, the usage time/air time shall be
tracked by total usage time/air time of the group/pool rather than by the
individual MTS unit.

e. Prior to the end of this contract, the contractor should provide a means by
which the Government may acquire and pay for subsequent usage time/air time
usage for systems they already own.

f. The data contained in the table below is provided as information only. The
numbers are estimates. Actual government usage is unknown and is dependent on
many factors such as the addition of applications identified in Paragraph
III.2.15 of this document. This information is not meant to change or modify the
Government's requirement for "fixed price for continuous unlimited usage on a
daily basis, i.e. $X/per day/per unit unlimited use."

(1) Training Analysis Process. A front end training analysis will be
accomplished to develop a general training concept, a training Master Task List
(MTL), and identify the Terminal Learning Objectives and Enabling Learning
Objectives to support each task. Subject matter experts (SME) will subsequently
review the analysis. Following approval of the MTL, a Task Selection Matrix
(TSM) will be developed, critical tasks identified for training, and methods of
training will be determined. An Instructional Media Design Report (IMDR)
(details the flow, appearance, and subject matter of the interactive courseware)
will be completed and training scenarios reflecting operational environments
will be developed. From the approved TSM, tests for each task will be developed,
draft Programs of Instruction (POI), Lesson Plans (LP) Storyboards, Handouts
(HO), Practical Exercises (PE), and a Training Database will be developed. As
the system matures, a Detailed Task Selection Matrix will be developed to
identify step-by-step procedures required to accomplish each task. Draft
Training Packages and supporting documentation will be tested and adjusted prior
to the Operational Test (OT). SME support will be provided/coordinated by USA
Combined Arms Support Command (CASCOM) throughout the development process. The
development contractors will visit and/or coordinate directly with designated
Points of Contact (POC)

(2) Multimedia Training. Multimedia Training shall be the primary method of
training for the MTS. The multimedia training will be on a separate CD ROM that
must be periodically updated to reflect the changes to the system. It will
satisfy the majority of the requirements for extension, sustainment, collective,

(c) A multimedia package will be developed. It must have hooks embedded into the
prime system software (embedded training) so the user can obtain access to the
training system and receive training by clicking on the hyper text, go to
training, and return to the work area (training itself may be on CD-ROM). This
will be an option load with the prime system. The training package must also be
capable of operating separately, to provide the capability for conduct of
initial or sustainment training; it will be MTS specific and capable of use on
any compatible DOS computer. Training screens will be identical to the prime
system screens and help capabilities.

(3) Paper-Based Training. Paper-based training will be developed for designated
tasks and those tasks not identified for embedded training. These packages must
contain approved task lists, Programs of Instruction (POIs) and Lesson Plans (to
include handouts, slides, practical exercises and tests) to assist the unit in
conducting sustainment training.

(4) System Extension Training (SET). A training team will conduct operator and
Control Station operator training at each training location. The extension
packages will include training for all critical tasks identified during the
Front End Analysis and the design and development efforts that were selected for
training. The approved training package will be utilized to provide this initial
training. The training will be provided on-site at each extension location that
has system hardware being fielded to that site. Representative system hardware
will be utilized. Monitorship and on-the-job training will occur following
classroom training and system extension. The purpose of the monitorship is to
ensure training effectiveness. Over-the-shoulder individual assistance will be
provided as required, until the training team is satisfied that the operators
and managers have the capability to exercise the system to its full capacity.
The team will ensure full conversion and operation of the system prior to
departure from the installation.

(5) Unit / Sustainment Training. Multimedia Embedded Training (EI) will be
provided with the system and will have hooks resident in the system software to
effect ET. Training CD-ROM disks will also be provided. A complete copy of the
system extension training package, to include those tasks not selected for ET
(including POI, Lesson Plans, and any other paper-based material), will be
provided to units for unit sustainment training. Commanders of TOE / TDA units
are responsible for conducting unit sustainment training as required.

(6) Training Evaluation and Manual Verification. USA CASCOM training evaluators
will conduct a training Operational Test and Readiness Evaluation (OTRE) of the
final training package when the operational test players are being trained. An
OTRE will be conducted for all training provided. The training will include ET,
Help, the Program of Instruction (POI), Task Selection Matrix (TSM), Lesson
Plans (LP)/Story Boards, Practical Exercises (PE), test, tutorials and manuals
(on-line and paper-based). USA CASCOM will issue a training Operational Test
Readiness Statement (OTRS) through TRADOC to OPTEC as a result of the OTRE. To
insure a successful OTRE, the PM MTS should request a customer test by USA
CASCOM at any time prior to the OT.

u.  RESERVED

v. The Contractor shall certify with the submission of the proposal, that V1
and V2 Mobile Units are safe to use as close as five inches from unsbielded
munitions that contain 10 mA no-fire current, electro-explosive devices (EEDs).
This certification shall be required for each type of RF component provided on
the Contract, throughout the life of the Contract. A determination of the
required safe separation distance can be made by referring to the graph entitled
"Safe Separation Distance Between an RF Source and Unshielded Munitions
Containing 10 mA No-fire Current Electro-Explosive Devices (EEDs)" in Exhibit-A.
This graph relates safe separation distances to irradiated output power as a
function of operating frequency. Although many ordnance items have no EEDs, and
other items have EEDs that are less sensitive to RF energy, this requirement
represents a worst-case scenario that ensures safe operation around what
frequently is unknown ordnance (unknown to transporters and others).
Transmitters, RF Relays and any other emitter shall be furnished, with a
warning label that clearly indicates the safe separation distance that must be
maintained between ordnance and the irradiating source.

w. The MTS shall provide positive acknowledgement to the message sender/user.

APPENDAGE# 1                        TO DD FORM 254

             SAFEGUARDING "FOR OFFICIAL USE ONLY" (FOUO) INFORMATION

                    Provided by the Security Support Division
               Directorate for Intelligence & Information Security

1. The "For Official Use Only" (FOUO) marking is assigned to information at the
time of its creation in a DOD User Agency. It is not authorized as a substitute
for a security classification marking but it is used on official government
information that may be withheld from the public under exemptions 2 through 9 of
the Freedom of Information Act.

2. Other non-secutity markings, such as "Limited Official Use" and "Official Use
Only" are used by non-DoD User Agencies for the same type of information and
should be safeguarded and handled in accordance with instructions received from
such agencies.

3. Use of the above markings does not mean that the information cannot be
released to the public, only that it must be reviewed by the Government prior to
its release to determine whether a significant and legitimate government purpose
is served by withholding the information or portions of it.

4. IDENTIFICATION MARKINGS

       a. An unclassified document containing FOUO information will be marked
"FOR OFFICIAL USE ONLY" at the bottom of the front cover (if any), on the
first page, on each page containing FOUO information, on the back page, and on
the outside of the back cover (if any). No portion marking will be shown.

b. Within a classified document an individual page that contains FOUO and
classified information will be marked at the top and bottom with the highest
security classification appearing on the page. If an individual portion contains
FOUO information but no classified information, the portion will be marked,
"FOUO".

c. Any "FOR OFFICIAL USE ONLY" information released to a contractor by a DoD
User Agency is requi!red to be marked with the following statement prior to
transfer.

THIS DOCUMENT CONTAINS INFORMATION EXEMPT FROM MANDATORY DISCLOSURE UNDER THE
FOIA. EXEMPTIONS ----------- APPLY

d. Removal of the "FOR OFFICIAL USE ONLY" marking can only be accomplished by
the originator or other competent authority. When "FOR OFFICIAL USE ONLY" status
is terminated, all known holders will be notified to the extent practical.

S. DISSEMINATION: Contractors may disseminate "FOR OFFICIAL USE ONLY"
information to their employees and subcontractors who have a need for the
information in connection with a classified contract.

6. STORAGE During working hours, "FOR OFFICIAL USE ONLY" information shall be
placed in an out-of-sight location if the work area is accessible to persons who
do not have a need for the information. During nonworking hours, the information
shall be stored to preclude unauthorized access. Filing such material with other
unclassified records in unlocked files or desks, is adequate when internal
building security is provided during



<PAGE>

nonworking hours. When such internal security control is not exercised, locked
buildings or rooms will provide adequate after-hours protection or the material
can be stored in locked receptacles such as file cabinets, desks or bookcases.

7. TRANSMISSION: "FOR OFFICIAL USE ONLY" information may be sent via first-class
mail or parcel post. Bulky shipments may be sent by fourth-class mail.

8. DISPOSITION: When no longer needed, FOUO information may be disposed of by
tearing each copy into pieces to preclude reconstructing, and placing it in a
regular trash container or as directed by the User Agency.

9. UNAUTHORIZED DISCLOSURE: Unauthorized disclosure of "FOR OFFICIAL USE ONLY"
information does not constitute a security violation but the releasing agency
should be informed of any unauthorized disclosure. The unauthorized disclosure
of FOUO information protected by the Privacy Act may result in criminal
sanctions.

      3.2   Mobile Satellite Terminal License.

      In consideration of CMDC's obligations under this Agreement, Vistar hereby
      grants to CMDC during the Term of this Agreement only:

          (i)  a  non-exclusive,   non-transferable   license  to  use,  modify,
               maintain, lease or sell Mobile Satellite Terminals containing MST
               Technology;
          (ii) subject to the provisions of Subsection 3.2(iv), a non-exclusive,
               non-transferable  license to  provide,  to the MST  manufacturers
               selected  by  CMDC,  the MST  Technology  excluding  Source  Code
               required  by  such   manufacturers   for  the  sole   purpose  of
               manufacturing MSTs. However,  the Parties expressly agree that in
               the event the manufacturer selected by CMDC is not located in the
               United  States or  Canada,  CMDC must  obtain  the prior  written
               consent  of  Vistar,  which  consent  shall  not be  unreasonably
               withheld, for release of MST Technology to the Manufacturer;
          (iii)notwithstanding   Subsection   3.2(i)   above,   subject  to  the

               subject to the terms of  Subsection  3.2(iv) as well as any other
               commercially reasonable terms stipulated by Vistar, Vistar agrees
               to grant CMDC the right to sub-license MST Technology,  on a case
               by case basis, to third parties.  The Parties hereby  acknowledge
               that such  commercial  terms may,  in Vistar's  sole  discretion,
               include  amendments to, or replacements  of, the terms respecting
               Royalties.  In such an event, the Parties agree, for the purposes
               of only the specific  sub-license under  consideration,  to enter
               into a written agreement  reflecting any such amendments.  In the
               event that  Vistar  grants its  consent  to a  sub-license  it is
               expressly  understood  that  CMDC  remains  responsible  for  the
               payment  to  Vistar  of  all  Royalties   associated   with  MSTs
               sub-licensed  in  accordance  with the  terms of this  Subsection
               3.2(iii)  and/or for any other payments due to Vistar pursuant to
               the said modifications to the Royalty terms;
          iv)  In the event that MST  Technology,  or part thereof is authorized
               by Vistar for release to a third party  manufacturer  pursuant to
               Subsection  3.2(ii) above,  or the granting of a sub-license to a
               third  party is  authorized  by  Vistar  pursuant  to  Subsection
               3.2(iii) then as a pre-condition to the said authorization coming
               into effect, CMDC must enter into (i) a sub-license agreement, in
               a form satisfactory to Vistar,  with such third party stipulating
               the terms of the

                                      6

<PAGE>



               sub-license; and (ii) a Confidentiality Agreement in the form set
               out in Schedule D with such third  party and Vistar.  CMDC hereby
               agrees  to  indemnify   Vistar  for  all  losses  and/or  damages
               including,  without  limitation,  legal fees,  resulting from the
               breach of such agreement by such third party.

      3.3   Royalties.

          (i)  CMDC will also pay to VISTAR, upon successful production and sale
               of Mobile Satellite  Terminals,  a Royalty calculated at the rate
               of XX dollars  ($XX) per MST for up to and including
               each of the first ten thousand  (10,000)  terminals  produced and
               sold, and XX dollars  ($XX) per terminal for each and every
               terminal produced and sold thereafter.

          (ii) Unless the Term of this Agreement is extended pursuant to Section
               6.2,  the Royalty  shall be payable for a period of six (6) years
               commencing on the production of the first  commercial MST. In the
               event that the Term of the  Agreement  is  extended  pursuant  to
               Section  6.2 then the  Royalty  shall  continue  to be payable to
               Vistar for an additional  period  equivalent to the length of the
               extension to the Term. It is expressly  agreed that in accordance
               with this methodology,  CMDC's  obligations to pay Royalties will
               continue after the expiration of the Term of the Agreement  until
               the   expiration  of  the  periods  of  time  described  in  this
               Subsection.

          (iii)Royalties  shall be paid on a quarterly  basis with the  payments
               reflecting the Royalties  associated  with MSTs produced and sold
               during the immediately  preceding quarter. A report detailing the
               Royalty  calculation shall be provided with each Royalty payment.
               On an annual  basis,  at Vistar's  option,  Vistar can request an
               audit of the Royalty  calculation.  The audit will be at Vistar's
               expense  unless it is  determined  through  the  audit  that CMDC
               failed to pay any Royalties owing to Vistar under this Agreement,
               exceeding five percent (5%) of the Royalty amount paid by CMDC in
               which case, CMDC shall bear all costs of the audit.

      All documents (in whatever form,  including machine readable or electronic
      form) and other product materials owned by a Party must contain all proper

            Each Party agrees:

          (i)  to observe  confidentiality  with  respect  to the other  Party's
               Confidential Information;

          (ii) not to disclose,  or permit any third party or entity  access to,
               the  Confidential  Information (or any portion  thereof)  without
               prior written permission of the Disclosing Party; and

          (iii)to ensure that any  employees,  or any  authorized  third parties

               regard  to  the  Confidential   Information  procedures  no  less
               restrictive than the procedures used by such Party to protect its
               own similar  confidential and proprietary  information,  but at a
               minimum commercially reasonable procedures.

      8.4   Breach and Survival.

      It is expressly agreed and understood by the Parties that a breach of this
      Section 8 shall be deemed a Material Breach of this Agreement which breach

9.    INTELLECTUAL PROPERTY RIGHTS INDEMNITY

      9.1   Defense by CMDC.

            Except as provided in Subsection  9.2 below,  CMDC shall defend,  at
            its own expense,  any action  brought  against  Vistar to the extent
            that such  action is based  upon an IP Claim  that the use of MST by
            CMDC,  its  permitted   licenses   and/or   assigns   infringes  any
            Intellectual Property rights of a third party.

      9.2   Defense by Vistar.

          (i)  Vistar shall defend,  at its expense,  any action brought against
               CMDC to the  extent  that it is based on a claim  that the use of
               the MST Technology developed by Vistar infringes any Intellectual
               Property Right of any third party ("IP Claim" or "IP  Claimant").
               CMDC agrees to notify Vistar promptly in writing of any IP Claim,
               to permit  Vistar to defend,  compromise  or settle such IP Claim
               and to provide  reasonably  available  information and assistance
               regarding such IP Claim;  provided that if Vistar fails to retain
               defense  counsel  for any such  claim,  CMDC may  retain  its own
               defense counsel and defend against such IP Claim.
          (ii) Should  the MST  Technology  in the  opinion  of  Vistar's  Legal
               Counsel,  be likely to become the subject of an IP Claim,  Vistar
               shall either:

               a.   Procure for CMDC, at no cost to CMDC,  the right for CMDC to
                    continue  exercising  the  rights  granted  under  the  CMDC
                    License;
               b.   Replace or modify the MST  Technology  at no cost to CMDC to
                    make the MST  Technology  non-infringing,  provided that the
                    replacement    or   modified   MST    Technology    provides
                    substantially similar functionality and performance; or
               c.   If  neither  a. or b.  is  technically  feasible,  terminate
                    CMDC's then existing  rights under this Agreement and refund
                    of all  amounts  already  paid to Vistar by CMDC  under this
                    Agreement, including all Royalties.

     9.3  Limitation.  Vistar  shall have no  liability  for any IP Claim to the
          extent  that it is based  upon the  operation  or use of CMDC or third
          party  designs,  applications,  products or  materials  not  supplied,
          specified or approved by Vistar in writing and such IP Claim would not
          have occurred but for the use of such  unapproved  CMDC or third party
          designs, applications, products or materials, even if the operation or
          use of such designs, applications,  products or materials is permitted
          by the terms of CMDC's License.

                                      12

     9.4  Notification of Unauthorized Use. Each Party shall promptly notify the
          other in writing upon its discovery of any allegedly  unauthorized use
          or infringement of the MST Technology or the Confidential Information.
          In the event  that an  action  is  brought  regarding  such  allegedly
          unauthorized  use or  infringement,  the Parties shall  co-operate and
          provide full  information  and  assistance to each other in connection
          with any such action or proceeding.

               notice,

               a.   upon  the   institution   by  either  Party  of  insolvency,
                    receivership or bankruptcy proceedings,
               b.   upon the  institution  against  either Party of  insolvency,
                    receivership or bankruptcy proceedings,  if such proceedings
                    are not  dismissed  within  ninety  (90) days of the Party's
                    receipt of notice of such proceedings against it;
               c.   upon either  Party's making an assignment for the benefit of
                    creditors of all or part of its assets, or
               d.   upon either Party's dissolution or ceasing to do business or
                    upon  a  decision  by  the  Shareholders   and/or  Board  of
                    Directors of either Party to cease to do business.
          (ii) Upon the  occurrence of any of the events set forth in Subsection
               11.1 (i),  the Party  making the  filing,  assignment,  receiving
               notice  thereof,  or dissolving  or ceasing to do business  shall
               immediately inform the other Party in writing of such event.
          (iii)Upon the  occurrence of any of the events in Subsection  11.1(i),
               in the event that  Vistar is the party with  respect to which the
               event occurred, CMDC shall be entitled to exercise the rights set
               out in Section 12.

      11.2  Termination for Material Breach.

            Except in the case of a Material  Breach of Sections 8, in the event
            of a Material Breach of any provision of this License Agreement, the
            non-breaching  Party may terminate this License  Agreement by giving
            thirty  (30)  days  prior  written  notice to the  breaching  Party;
            provided,  however,  that this License Agreement shall not terminate
            if the breaching  Party has cured the breach prior to the expiration
            of such thirty  (30) day period,  or if subject to the terms of this
            Agreement  any Dispute  regarding  such breach has been  referred to
            Arbitration in accordance  with the provisions of Section 13. In the
            event of a  Material  Breach  of  Sections  8, if the  breach is not
            capable  of  being  cured  to  the  reasonable  satisfaction  of the
            non-breaching Party, the Party not in default may elect to terminate
            this License  Agreement  upon ten (10)  business  days prior written
            notice to the Party in default. In such circumstances, the Agreement
            shall  terminate  at the  conclusion  of this notice  period  unless
            otherwise mutually agreed upon by the Parties.

      In the event of any Dispute, each Party shall provide the other Party with
      written notice setting forth the outstanding  issues and positions of such
      Party   regarding   such  Dispute.   It  shall  be  the   obligation   and
      responsibility  of each  Party  to use his or her  best  efforts,  in good

      If the Parties are unable to resolve a Dispute  within thirty (30) days of

      arising under Section 8, any such Dispute shall be settled by  arbitration
      in accordance with the Ontario Arbitration Act. The Parties shall mutually
      select a single  arbitrator.  If the  Parties  are  unable to agree on the

      selection process,  then the number of arbitrators shall be three (3), and
      each Party  shall  select one  arbitrator  and the two  arbitrators  shall
      mutually  select and agree upon the third  arbitrator.  The Parties  shall
      provide the arbitrators and any expert  witnesses with all information and
      resources they may require to make their  decision.  Any failure of either
      Party to comply  with such  request of the  arbitrators  shall be deemed a
      Material Breach of this License Agreement.  An arbitration  decision shall
      be  binding.  The  prevailing  Party may enter such  decision in any court
      having competent  jurisdiction and failure to comply with such arbitration
      decision shall result in a Material Breach by the non-complying Party. The
      arbitration  proceeding  shall be  conducted  in the  English  language in
      Ottawa,  Ontario,  unless the  Parties  agree in  writing  to conduct  the
      arbitration  in  another  location.  Failure  of  either  Party to  attend
      arbitration shall result in a Material Breach by the absent Party.

                                      18

      15.11 Cumulation of Remedies.

      Except as  otherwise  expressly  stated  in this  License  Agreement,  all
      remedies  available to either  Party for breach of this License  Agreement
      are  cumulative  and may be exercised  concurrently  or separately and the
      exercise of any one remedy  shall not be deemed an election of such remedy
      to the exclusion of other remedies.

      15.12 Equitable Relief.

      The Parties agree that certain breaches of this Agreement may give rise to
      injuries that are not fully compensable by damages. Therefore, the Parties
      acknowledge and agree that in addition to any other remedies  available at
      law, and  notwithstanding the provisions of Section 12.2, a Party shall be
      entitled to apply to a court of competent jurisdiction and seek injunctive
      or  other  equitable  relief,  including,  without  limitation,   specific
      performance,  from the other Party to enjoin any breach by the other Party
      of the provisions of this Agreement.

      15.13 Interest.

      Any amount that is not paid when due will bear  interest  until fully paid
      at the rate of the  lesser of (i) one  percent  and one half  (1.5%),  per
      month compounded monthly, or (ii) the highest rate permitted by applicable
      law.  Vistar shall also be entitled to recover its costs and expenses,  if
      any, incurred in collecting such amount.  Vistar's entitlement to interest
      shall in no way effect CMDC's  obligations  to make payments in accordance
      with Section 4 of this Agreement, and Vistar's acceptance of such interest
      shall not be deemed to be waiver of any of CMDC's  obligations  respecting
      payments.

      15.14 Waiver.

      No term or provision  hereof shall be deemed waived and no breach  excused
      unless such waiver or consent  shall be in writing and signed by the Party
      claimed to have waived or  consented,  and such written  waiver shall only
      serve to waive or  excuse,  as the case may be, the  particular  breach to
      which it applies and no other.

      15.15 Force Majeure.

      Each Party shall be excused from performance  under this License Agreement
      and shall  have no  liability  to the other  Party for any period if it is
      prevented  from  performing  any of its  obligations  (other than  payment
      obligations)  in whole or in part,  as a result of delays caused by an act
      of God, war, civil disturbance,  company or industry-wide labour disputes,
      or other cause  beyond its  reasonable  control  and such  non-performance
      shall not be a default under,  or grounds for  termination of this License
      Agreement.  However,  if a Force Majeure event continues for more than one
      hundred and eighty  (180) days,  then the Party whose  performance  is not
      affected  by the Force  Majeure  shall  have the right to  terminate  this
      License Agreement.

      they  were  set  forth  in this  License  Agreement.  In the  event of any
      conflict or inconsistency between the provisions of this License Agreement
      and one or more of the Schedules,  the conflict or inconsistency  shall be
      resolved in favour of the License Agreement.

      the  Schedules  attached  hereto and forming part  hereof,  and each Party
      understands and agrees to be bound by its terms and conditions.

      Schedules hereto,  shall be effective unless reduced to writing and signed
      by the Parties hereto.

      15.19 Expenses.

      Travel and living expenses incurred by Vistar shall be invoiced to CMDC at
      cost  with  associated  receipts.  Travel  and  living  expenses  must  be
      authorized in advance by CMDC.

      15.20 Operating Systems.

      To  the  extent  permitted  by  law  or  Vistar's   existing   contractual
      obligations,  Vistar  agrees to make  available  to CMDC the  Precise  MQX
      Operating System license  associated with the CMDC terminal for a price of
      $XX.

      15.21 Survival.

      Except as otherwise provided in this License Agreement,  the provisions of
      Sections 4, 5, 7, 8, 9, 10 and 15 with the exception of Subsections 15.15,
      15.17,  15.18,  15.19, 15.20 and Subsections 3.1, 3.3 and 13.2, as well as
      the guarantees and/or indemnifications in Subsections 3.2(iii) and 3.2(iv)
      shall survive the termination or rescission of this License  Agreement for

      extend or override a  statutory  limitation  on the time within  which any
      action or actions based on this License Agreement may be brought.

      15.22 Publicity.

      Any press  release or other  publication  by either  Party  regarding  the
      existence  or terms of this  License  Agreement  must be  approved by both
      Parties prior to its publication.

      15.23 Entire Agreement.

      This License Agreement, together with Schedules A, B, C, D and E set forth
      and  constitutes  the entire  agreement  by and between  the Parties  with
      respect to the  development and licensing of MST Technology and supersedes
      any and all prior agreements,  understandings and representations  made by
      the Parties  concerning the subject matter of this Agreement.  For greater
      certainty it is expressly  acknowledged  and agreed that  co-incident with
      the execution of this  agreement the MOA and  amendments  thereto shall be
      terminated and each Party releases the other of all obligations under that
      agreement.
