THE COMPANY'S ACTUAL RESULTS COULD DIFFER SIGNIFICANTLY FROM THE RESULTS
DISCUSSED IN THE FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE OR
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE THOSE DISCUSSED IN "RISK FACTORS" AS WELL
AS THOSE DISCUSSED ELSEWHERE IN THIS PROSPECTUS. THE COMPANY HAS RECENTLY
CHANGED ITS NAME FROM WORLDCOMM SYSTEMS INC. TO GLOBECOMM SYSTEMS INC.
 
                                  THE COMPANY
 
    Globecomm Systems Inc. ("GSI" or the "Company") designs, assembles and
installs satellite ground segment systems and networks which support a wide
range of satellite communications applications, including fixed, mobile and
direct broadcast services as well as certain military applications. The
Company's customers include prime communications infrastructure contractors,
government-owned postal, telephone and telegraph providers ("PTTs"), other
telecommunications carriers, producers and distributors of news and
entertainment content and other corporations. The Company's ground segment
systems typically consist of an earth station, which is an integrated system
designed to transmit and receive signals to and from satellites, together with
ancillary subsystems. The Company's ground segment networks are typically
comprised of two or more ground segment systems communicating with a satellite
and interconnected with a terrestrial network. Since the Company commenced
operations in August 1994, it has completed the installation of 35 ground
segment systems and networks for 24 customers in 18 countries.
 
    During the six months ended December 31, 1996, the Company booked $28.8
million in contract orders and at December 31, 1996 had a backlog of $27.1
million of contract orders. The Company believes that its historical performance
and its ability to compete successfully in the future are based on its unique
combination of competitive advantages which include: (i) an experienced
management group with extensive technological and engineering expertise, (ii)
the proven ability to meet the complex satellite ground segment requirements of
its customers in diverse political, economic and regulatory environments in
various locations around the world and (iii) its ability to identify, develop
and maintain strategic relationships with developers and suppliers of
leading-edge technologies which enhance performance, reduce costs and broaden
applications of the Company's ground segment systems and networks.
 
    The Company has recently established a subsidiary, NetSat Express, Inc.
("NetSat"), to develop service revenues by providing high-speed,
satellite-delivered data communications to developing markets worldwide. In
order to accomplish this objective, NetSat intends to leverage: (i) the
Company's expertise in satellite ground segment system and network
implementation, (ii) extensive management experience in providing
satellite-delivered communications services, (iii) the knowledge and
capabilities of local market strategic partners and (iv) DirecPC and Personal
Earth Station technology developed and owned by Hughes Network Systems, Inc., a
subsidiary of Hughes Electronics Corp. ("Hughes Network Systems" or "HNS"). Any
use by NetSat of HNS' DirecPC technology will require the grant of a license
from HNS to NetSat. NetSat currently is pursuing joint ventures with local
partners in Russia and Brazil to market low-
 
                                       3
<PAGE>
cost, high-speed satellite Internet access services, as well as intranet
services, to corporate, educational and government customers who have limited or
no access to terrestrial network infrastructure capable of supporting the
economical delivery of such services.
 
    According to Federal Communications Commission (the "FCC") estimates,
providers of satellite-delivered communications services generated approximately
$13.8 billion in revenues in 1995, which amount is projected to grow at a
compound annual rate of 21% to approximately $37.0 billion in 2000. The Company
believes this expected growth in satellite communications services will require
significant investment in new ground segment system and network infrastructure.
Based on industry sources, the markets for ground segment systems and networks
in which the Company competes had aggregated revenues of approximately $1.6
billion in 1996 and are projected to grow at a compound annual rate of
approximately 11% to revenues of approximately $2.5 billion by the year 2000.
Although there are currently no reliable data available on the market for
satellite-delivered Internet and intranet applications in developing countries,
a market in which the Company participates through NetSat, the Company believes
such market has potential for rapid growth. The FCC has estimated that
satellite-delivered data communications services accounted for approximately
$1.3 billion of service revenues worldwide in 1995 and that this amount will
grow at a compound annual rate of approximately 26% to revenues of approximately
$4.2 billion in 2000.
 
    The Company believes that the growth in demand for ground segment
infrastructure is principally a result of the following major factors: (i)
global deregulation and privatization of government-owned monopoly
telecommunications carriers and the emergence of competitive carriers, each of
which is driving capital investment, (ii) rapidly growing worldwide demand for
communications services generally, including data communications services over
the Internet and corporate intranets, (iii) relative cost-efficiency of
satellite communications for many applications and (iv) technological
advancements which reduce costs and increase capacity, thereby broadening
applications for both satellite and terrestrial networks.
 
    The Company's business strategy is to expand its market share in its ground
segment systems and networks business, improve its profitability and create
opportunities to capture recurring service revenues. The Company intends to
execute this strategy by: (i) targeting communications infrastructure
development opportunities worldwide, (ii) focusing on high margin
engineering-intensive ground segment system and network projects, (iii)
developing strategic customer relationships, (iv) developing strategic supplier
relationships and (v) entering the satellite-delivered data communications
services business through NetSat.
 
    The Company seeks to build close relationships with customers for whom it
can provide complementary engineering skills by working as part of their system
development teams. A key objective of this strategy is to obtain this business
on a negotiated basis, rather than through the competitive bidding process,
which is likely to carry a lower margin. To date, the Company has developed
strategic relationships with two of its customers: Hughes Network Systems and
Thomson-CSF S.A. ("Thomson"). The Company sought the establishment of these
relationships based on these customers' abilities to: (i) generate significant
potential revenues for the Company, (ii) provide access to a large number of
potential business opportunities as a result of their size and global operations
and (iii) provide access to complementary technologies and expertise that could
serve as competitive advantages for the Company. At January 31, 1997, Hughes
Network Systems and Thomson owned equity interests in the Company of 3.7% and
4.9%, respectively. In addition, Hughes Network Systems owns a 19% equity stake
in NetSat, with an option to increase this position to 29%.
 
    In addition to its strategic customer relationships, the Company also seeks
to develop strategic relationships with suppliers which it believes are each in
a position to supply products, technologies or services which will improve the
Company's competitive position in one or more of the market segments it serves.
As of December 31, 1996, the Company has made equity investments aggregating
approximately $835,000 in three such companies. These suppliers enable the
Company to outsource a significant portion
 
                                       4
<PAGE>
of its research and development efforts and gain access to advanced technology
while the Company continues its independence to select the most suitable
products and technologies to deliver to its customers from any suppliers.
 
    The Company was incorporated in Delaware on August 17, 1994. The Company's
principal executive offices are located at 375 Oser Avenue, Hauppauge, New York
11788, and its telephone number is (516) 231-9800.

<PAGE>
                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK
FACTORS SHOULD BE CAREFULLY CONSIDERED IN EVALUATING THE COMPANY AND ITS
BUSINESS BEFORE PURCHASING SHARES OF COMMON STOCK OFFERED HEREBY.
 
LIMITED OPERATING HISTORY; HISTORY OF OPERATING LOSSES AND ACCUMULATED DEFICIT
 
    The Company, which was formed in August 1994, has a limited operating
history upon which an evaluation of the Company and its prospects can be based
and has incurred significant operating losses since its inception. The Company
generated its first revenue from its ground segment systems and networks
business in June 1995 and has generated only minimal revenues from its
satellite-delivered data communications services business, which commenced
operations in July 1996. The Company incurred operating losses of $1.1 million,
$2.3 million and $1.2 million during the fiscal years ended June 30, 1995 and
1996 and during the six-month period ended December 31, 1996, respectively. The
Company currently anticipates that it will incur further operating losses as it
attempts to expand its business, and there can be no assurance that the Company
will generate significant additional revenues or will ever generate positive
operating or net income. As of December 31, 1996, the Company had an accumulated
deficit of $4.2 million. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations-- Liquidity and Capital Resources."
 
INTENSE COMPETITION; LIMITED BARRIERS TO ENTRY
 
    The markets for both ground segment systems and networks and
satellite-delivered data communications services are highly competitive. Many of
the Company's competitors have greater market presence, engineering and
marketing capabilities, and financial, technological and personnel resources
than those available to the Company. As a result, such competitors may be able
to develop and expand their products and services more quickly, adapt more
swiftly to new or emerging technologies and changes in customer requirements,
take advantage of acquisition and other opportunities more readily, and devote
greater resources to the marketing and sale of their products and services than
can the Company. In addition, there are limited barriers to entry in the
Company's markets and certain of the Company's strategic suppliers and customers
have technologies and capabilities in the Company's product areas and could
choose to compete with the Company or to replace the Company's products or
services with their own. The entry of new competitors, the decision by a
strategic ally to compete with the Company or the decision by a customer to
develop and employ in-house capability to satisfy its satellite communications
needs could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Competition."
 
    There can be no assurance that the Company's competitors will not develop or
acquire competing products or that such products will not be offered at
significantly lower prices. In addition, current and potential competitors in
both markets in which the Company competes have established or may establish
cooperative relationships among themselves or with third parties to increase the
ability of their products and services to address the needs of the Company's
current and prospective customers. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. Increased competition is likely to result in price
reductions, reduced gross profit margins and loss of market share, any of which
would have a material adverse effect on the Company's business, results of
operations and financial condition. There can be no assurance that the Company
will be able to compete successfully against current or future competitors or
that competitive pressures will not have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business-- Competition."
 
    The Company also is dependent on the continued success and development of
the satellite communications industry, which itself competes with other
technologies such as terrestrial microwave, copper wire
 
                                       7
<PAGE>
and fiber optic communications systems. Any failure of the satellite
communications industry to continue to develop, or any technological development
which significantly improves the capacity, cost or efficiency of such competing
systems relative to satellite systems, could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"--Rapid Industry Change; Technological Obsolescence."
 
RELIANCE ON STRATEGIC RELATIONSHIPS
 
    The Company is dependent on certain customers and suppliers for the
development and expansion of its ground segment system and network business.
However, such relationships are not governed by any contract and accordingly
neither the Company nor such customers or suppliers are obligated to maintain
such strategic relationships. There can be no assurance that the Company will be
able to maintain such strategic relationships, that its strategic customers and
suppliers will continue to assist the Company by developing and expanding its
business and by providing research and development expertise, or that such
strategic customers and suppliers will not actually compete with the Company in
the future. See "--Intense Competition; Limited Barriers to Entry."
 
    In addition, the Company relies on the Personal Earth Station and DirecPC
technologies provided by Hughes Network Systems in connection with the planned
operation of NetSat's satellite-delivered data communications services business.
Any use by NetSat of HNS' DirecPC technology will require the grant of a license
from HNS to NetSat. Hughes Network Systems is under no obligation to grant such
licenses and there can be no assurance that NetSat will be able to negotiate
such licensing arrangements with Hughes Network Systems on acceptable terms, or
at all. In addition, failure to maintain a business relationship with Hughes
Network Systems would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    Because the Company intends to provide its satellite-delivered data
communications services almost entirely in developing markets where the Company
has little or no market experience, the Company will also be dependent on local
partners in such markets to provide marketing expertise and knowledge of the
local regulatory environment in order to facilitate the acquisition of necessary
licenses and access to existing customers. The Company has not yet formally
established an alliance with a local partner. The Company's failure to form and
maintain such alliances with local partners, or the preemption or disruption of
such alliances by the actions of the Company's competitors or otherwise, would
adversely affect the Company's ability to penetrate and compete successfully in
such emerging markets. There can be no assurance that the Company will be able
to compete successfully in the future in such markets or that competition will
not have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Strategic Relationships" and
"--Competition."
 
CUSTOMER CONCENTRATION
 
    The Company typically relies upon a small number of customers for a large
portion of its revenues. For example, approximately 43% and 17% of the Company's
revenues in fiscal 1996 and for the six months ended December 31, 1996,
respectively, were derived from sales to Hughes Network Systems. At December 31,
1996, $16.5 million, or approximately 61% of the Company's backlog, was
accounted for by a contract between the Company and American Sky Broadcasting
LLC ("A Sky B"). The Company expects that in the near term a significant portion
of its revenues will continue to be derived from one or a limited number of
customers (the identity of whom may vary from year to year) as the Company seeks
to expand its business and its customer base. The reduction, delay, or
cancellation of orders from one or more of such significant customers would have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Customers."
 
MANAGEMENT OF RAPID GROWTH
 
    The Company has been significantly and rapidly expanding its operations
since its inception. In order to pursue successfully the opportunities presented
by the ground segment and emerging satellite-delivered
 
                                       8
<PAGE>
communications and Internet/intranet-infrastructure markets, the Company will be
required to continue to expand its operations. Such expansion has placed, and is
expected to continue to place, a significant strain on the Company's personnel,
management, financial and other resources. In order to manage any future growth
effectively, the Company will, among other things, be required to attract,
train, motivate and manage a significantly larger number of employees
successfully to conduct product engineering and management, product
implementation, sales activity and customer support activities; manage higher
working capital requirements; and improve its operating and financial systems.
Any failure to manage any future growth in an efficient manner and at a pace
consistent with the Company's business could have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview," "Business--Product Design, Assembly and Testing,"
"--Facilities" and "--Employees."
 
RISK OF FIXED-PRICE CONTRACTS
 
    Virtually all of the Company's contracts for installation of ground segment
systems and networks are on a fixed-price basis. Profitability of such contracts
is subject to inherent uncertainties as to the cost of performance. In addition
to possible errors or omissions in making initial estimates, cost overruns may
be incurred as a result of unforeseen obstacles, including both physical
conditions and unexpected problems encountered in engineering, design and
testing. Since the Company's business may at certain times be concentrated in a
limited number of large contracts, a significant cost overrun on any one
contract could have a material adverse effect on the Company's business,
financial condition and results of operations. See "--Customer Concentration."
 
INTERNATIONAL OPERATIONS
 
    Most of the Company's revenues are derived from sales to customers outside
the United States. Revenues from foreign sales accounted for 21.8% and 58.6% of
total revenues in fiscal 1996 and the six-month period ended December 31, 1996,
respectively, and the Company anticipates that foreign sales will continue to
account for a significant portion of total revenues in the foreseeable future.
The Company's foreign sales are generally denominated in U.S. dollars.
Consequently, a decrease in the value of foreign currencies relative to the U.S.
dollar may adversely affect demand for the Company's products and services by
increasing the price of the Company's products and services in the currency of
the countries in which they are sold. Additional risks inherent in the Company's
international business activities include various and changing regulatory
requirements, costs and risks of relying upon local subcontractors for the
installation of its ground segment systems and networks, increased sales and
marketing expenses, availability of export licenses, tariffs and other trade
barriers, political and economic instability, difficulties in staffing and
managing foreign operations, potentially adverse taxes, complex foreign laws and
treaties and the possibility of difficulty in accounts receivable collections.
In addition, the Company is subject to the Foreign Corrupt Practices Act (the
"FCPA") which may place the Company at a competitive disadvantage to foreign
companies, which are not subject to the FCPA. There can be no assurance that any
of these factors will not have a material adverse effect on the Company's
business, financial condition and results of operations.
 
EMPHASIS ON DEVELOPING MARKETS; UNCERTAIN MARKET POTENTIAL
 
    The Company believes a substantial portion of the growth in demand for its
ground segment systems and networks and its recently launched
satellite-delivered data communications services will come from customers in
developing countries. There can be no assurance that such increases in demand
will occur or that prospective customers will accept such products and services
in sufficient quantities or at all. The degree to which the Company is able to
penetrate potential markets in developing countries will be affected in major
part by the speed with which other competing elements of the communications
infrastructure, such as telephone lines, other satellite-delivered solutions and
fiber optic cable and television cable, are installed in the developing
countries and with respect to the Company's data communications services, on the
effectiveness of the Company's local partners in such markets. The failure
 
                                       9
<PAGE>
to have its products and services accepted in developing countries would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "--Intense Competition; Limited Barriers to Entry"
and "--Reliance on Strategic Relationships."
 
RAPID INDUSTRY CHANGE; TECHNOLOGICAL OBSOLESCENCE
 
    The telecommunications industry, including the satellite communications
ground segment systems and networks and data communication services businesses,
is characterized by rapid and continuous technological change. Future
technological advances in the telecommunications industry may result in the
availability of new products or services that could compete with the satellite
ground segment products and services provided by the Company or render the
Company's products and services obsolete. There can be no assurance that the
Company will be successful in developing and introducing new products and
services that meet changing customer needs or in responding to technological
changes or evolving industry standards in a timely manner, if at all, or that
services or technologies developed by others will not render the Company's
products or services noncompetitive. Any failure by the Company to respond to
changing market conditions, technological developments, evolving industry
standards or changing customer requirements, or the development of competing
technology or products that render the Company's products and services
noncompetitive or obsolete would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--Research
and Development" and "-- Competition."
 
DEPENDENCE UPON SUPPLIERS; SOLE AND LIMITED SOURCES OF SUPPLY
 
    The Company currently procures most of the critical components and services
for its products from single or limited sources in connection with specific
contracts and does not otherwise carry significant inventories or have long-term
or exclusive supply contracts with its source vendors. The Company has from time
to time experienced delays in receiving products from certain of its vendors due
to quality control or manufacturing problems, shortages of materials or
components or product design difficulties. There can be no assurance that
similar problems will not recur or that replacement products will be available
when needed at commercially reasonable rates, or at all. If the Company were to
change certain of its vendors, the Company would be required to perform
additional testing procedures upon the components supplied by such new vendors,
which could prevent or delay product shipments. Additionally, prices could
increase significantly in connection with changes of vendors. Any inability of
the Company to obtain timely deliveries of materials of acceptable quality or
timely services, or any significant increase in the prices of materials or
services, could have a material adverse effect on the Company's business,
financial condition and results of operations. See "--Risk of Fixed-Price
Contracts," "--Quarterly Fluctuations" and "Business--Product Design, Assembly
and Testing."
 
QUARTERLY FLUCTUATIONS
 
    The Company may in the future experience significant quarter to quarter
fluctuations in its results of operations, which may result in volatility in the
price of the Company's Common Stock. Quarterly results of operations may
fluctuate as a result of a variety of factors, including the timing of the
initiation and completion of contracts, the demand for the Company's products
and services, the introduction of new or enhanced products and services by the
Company or its competitors, market acceptance of new products and services, the
mix of revenues between custom-built satellite communications systems and
networks designed for its customers and standard installations provided to its
customers, the growth of demand for Internet infrastructure-based products and
services in developing countries, the timing of significant marketing programs,
the extent and timing of the hiring of additional personnel, competitive
conditions in the industry and general economic conditions. Due to the foregoing
factors, it is likely that in one or more future quarters the Company's
operating results will be below the expectations of public market analysts and
investors. Such an event could have a material adverse effect on the price of
the Company's Common Stock. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations-- Quarterly Results."
 
                                       10
<PAGE>
GOVERNMENT REGULATIONS
 
    The Company is subject to various federal laws and regulations which may
have negative effects on the Company. The Company intends to erect a teleport in
Hauppauge, New York, which will be subject to FCC Rules and Regulations. The
Company will be required to obtain a license from the FCC for both domestic and
international operation of the teleport and must operate it in compliance with
FCC Rules and Regulations for the term of the license. There can be no assurance
that the Company will be able to obtain or maintain the necessary license. See
"Business--Government Regulation."
 
    Under the FCC Rules and Regulations, non-U.S. citizens or their
representatives, foreign governments, or corporations otherwise subject to
control by non-U.S. citizens, may not own more than 20% of a licensee directly,
or, if the FCC finds it consistent with the public interest, may not own more
than 25% of the parent of a licensee. Non-U.S. citizens may not serve as
officers of a licensee or as members of a licensee's board of directors,
although the FCC may waive this requirement in whole or in part. Failure to
comply with these requirements may result in the FCC issuing an order to the
entity requiring divestiture of alien ownership to bring the entity into
compliance with the FCC Rules and Regulations. In addition, fines, a denial of
renewal or revocation of the license are possible. The Company has no knowledge
of any present foreign ownership which would result in a violation of the FCC
Rules and Regulations, but there can be no assurance that foreign holders will
not in the future hold more than 20% or 25% of the Common Stock of the Company.
 
    Regulatory schemes in countries in which the Company may seek to provide its
satellite-delivered data communications services may impose impediments on the
Company's operations. Certain countries in which the Company intends to operate
have telecommunications laws and regulations that do not currently contemplate
technical advances in broadcast technology such as Internet/intranet
transmission by satellite. There can be no assurance that the present regulatory
environment in any such country will not be changed in a manner which may have a
material adverse impact on the Company's business. The Company or its local
partners typically must obtain authorization for each country in which the
Company provides its satellite-delivered data communications services. Although
the Company believes that it or its local partners will be able to obtain the
requisite licenses and approvals from the countries in which the Company intends
to provide service, the regulatory schemes in each country are different and
thus there may be instances of noncompliance of which the Company is not aware.
Although the Company believes these regulatory schemes will not prevent the
Company from pursuing its business plan, there can be no assurance such licenses
and approvals are or will remain sufficient in the view of foreign regulatory
authorities, or that necessary licenses and approvals will be granted on a
timely basis in all jurisdictions in which the Company wishes to offer its
services or that restrictions applicable thereto will not be unduly burdensome.
See "Business--Government Regulation."
 
    The sale of the Company's ground segment systems and networks outside the
United States is subject to compliance with the regulations of the United States
Export Administration Regulations. The absence of comparable restrictions on
competitors in other countries may adversely affect the Company's competitive
position. In addition, in order to ship its products into European Union
countries, the Company must satisfy certain technical requirements. If the
Company were unable to comply with such requirements with respect to a
significant quantity of the Company's products, the Company's sales in Europe
could be restricted, which could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business--Government Regulation."
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's future success depends to a significant extent on its
executive officers and certain technical, managerial and marketing personnel.
The loss of the services of any of these individuals or group of individuals
could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company maintains term life insurance
in the amount of $1.0 million on David E. Hershberg, the Chairman and Chief
Executive Officer of the Company and term life insurance in the amount of
$500,000 for each of Messrs. Miller, DiCicco, Woodring, Yablonski and Melfi, all
of whom are
 
                                       11
<PAGE>
officers of the Company. The Company believes that its future success also will
depend significantly upon its ability to attract, motivate and retain additional
highly skilled technical, managerial and marketing personnel. Competition for
such personnel is intense, and there can be no assurance that the Company will
be successful in attracting, assimilating and retaining the personnel it
requires to grow and operate profitably. See "Management--Directors and
Executive Officers and Other Key Employees" and "Business--Employees."
 
PROPRIETARY TECHNOLOGY; RISK OF INFRINGEMENT
 
    The Company relies heavily on the technological and creative skills of its
personnel, new product developments, computer programs and designs, frequent
product enhancements, reliable product support and proprietary technological
expertise in maintaining its competitive position, and lacks patent protection
for its products and services. There can be no assurance that others will not
independently develop or acquire substantially equivalent techniques or
otherwise gain access to the Company's proprietary and confidential
technological expertise or disclose such technologies or that the Company can
ultimately protect its rights to such proprietary technological expertise.
 
    The Company generally relies on confidentiality agreements with its
consultants, key employees and sales representatives to protect its proprietary
technological expertise, and generally controls access to and distribution of
its technology, software and other proprietary information. Despite these
precautions, there can be no assurance that such agreements will not be
breached, that the Company will have adequate remedies for any such breach or
that a third party will not copy or otherwise obtain and use the Company's
products or technology without authorization or develop similar products or
technology independently. Failure by the Company to maintain protection of its
proprietary technological expertise for any reason could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Intellectual Property."
 
    The Company is subject to the risk of alleged infringement of intellectual
property rights of others. Most of the Company's officers and employees were
formerly officers or employees of other companies in the industry. The Company
believes that neither it nor its officers or employees have violated any
agreements with, or obligations to, prior employers. Although the Company is not
aware of any pending or threatened infringement claims with respect to the
Company's current or future products, there can be no assurance that third
parties, including previous employers, will not assert such claims or that any
such claims will not require the Company to enter into license arrangements or
result in protracted and costly litigation, regardless of the merits of such
claims. No assurance can be given that any necessary licenses will be available
or that, if available, such licenses can be obtained on commercially reasonable
terms. Furthermore, litigation may be necessary to enforce or protect the
Company's intellectual property rights, to determine the validity and scope of
the proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    The Company currently has two patent applications pending in the United
States and intends to seek further patents on its technology, if appropriate.
There can be no assurance that patents will issue from any of the Company's
pending or any future applications or that any claims allowed from such
applications will be of sufficient scope or strength, or be issued in all
countries where the Company's products can be sold, to provide meaningful
protection or any commercial advantage to the Company. Also, competitors of the
Company may be able to design around the Company's patents. The laws of certain
foreign countries in which the Company's products are or may be developed,
manufactured or sold may not protect the Company's products or intellectual
property rights to the same extent as do the laws of the United States and thus
make the possibility of piracy of the Company's technology and products more
likely.
 
    The Company has filed an application for registration of Globecomm Systems
Inc. as a service mark in the United States and has filed applications for
registration of NetSat Express as a trademark and service mark in the United
States, Singapore, the European Union and the Russian Federation and as a
 
                                       12
<PAGE>
trademark in Brazil, and intends to seek registration of other trademarks and
service marks in the future. There can be no assurance that registrations will
be granted from any of the Company's pending or future applications, or that any
registrations that are granted to the Company will prevent others from using
similar trademarks and service marks in connection with related goods and
services.
 
CONTROL BY EXISTING STOCKHOLDERS
 
    Upon completion of this Offering, the Company's officers and directors, and
their affiliates, will beneficially own approximately       shares, constituting
approximately    % of the Company's outstanding Common Stock. These
stockholders, if acting together, may be able to exert significant influence
over the election of directors and other corporate actions requiring stockholder
approval. See "Management" and "Principal Stockholders."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Sales of substantial numbers of shares of Common Stock in the public market
after this Offering could adversely affect the market price of the Common Stock.
Upon completion of this Offering, the Company will have outstanding       shares
of Common Stock. In addition to the       shares of Common Stock offered hereby,
as of the effective date of the Registration Statement of which this Prospectus
forms a part (the "Effective Date"), there will be 5,750,191 shares of Common
Stock outstanding, all of which are "restricted securities" under the Securities
Act. Certain stockholders of the Company are subject to lock-up agreements
providing generally that they will not offer to sell, sell, contract to sell,
grant any option to sell or otherwise dispose of any shares of Common Stock or
any securities convertible or exchangeable into Common Stock for a period of 180
days after the date of this Prospectus without the prior written consent of
PaineWebber Incorporated which may be given at any time, without notice, with
respect to all or any portion of such shares. Certain other stockholders of the
Company are subject to lock-up agreements providing generally that they will not
offer to sell, sell, contract to sell, grant any option to sell or otherwise
dispose of any shares of Common Stock or any securities convertible or
exchangeable into Common Stock for a period of one year after the date of this
Prospectus without the prior written consent of PaineWebber Incorporated which
may be given at any time, without notice, with respect to all or any portion of
such shares. Taking into account the lock-up agreements and notwithstanding
possible earlier eligibility for resale under the provisions of Rules 144 and
701, the numbers of shares that will be available for sale in the public market
will be as follows. Beginning 90 days after the Effective Date, approximately
      shares of restricted securities will become eligible for resale in the
public market. Beginning 180 days after the Effective Date, approximately
additional shares of restricted securities will become eligible for sale in the
public market upon expiration of certain lock-up agreements pursuant to Rules
144 and 701 and, as of that date, approximately       of such shares will be
subject to certain volume and other resale restrictions pursuant to Rules 144
and 701. Beginning one year after the Effective Date, approximately
additional shares of restricted securities will become eligible for sale in the
public market upon expiration of certain lock-up agreements pursuant to Rules
144 and 701 and, as of that date, approximately       of such shares will be
subject to certain volume and other resale restrictions pursuant to Rules 144
and 701.
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
    Prior to this Offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for the
Common Stock will develop or be sustained after the Offering. The initial public
offering price will be determined by negotiations between the Company and the
representatives of the Underwriters based upon several factors and may not be
indicative of future market prices. The market price of the Company's Common
Stock could be subject to wide fluctuations in response to quarterly variations
in operating results, announcements of technological innovations or new products
by the Company or its competitors, acceptance of satellite communication
services in developing countries, and other events or factors. In addition, the
stock market has experienced extreme price and volume fluctuations, which have
affected the market price of securities of many companies in the
 
                                       13
<PAGE>
telecommunications and high technology industries. These broad market
fluctuations may adversely affect the market price of the Company's Common
Stock. See "--Quarterly Fluctuations" and "Underwriting."
 
MANAGEMENT'S DISCRETION OVER APPLICATION OF PROCEEDS OF THE OFFERING
 
    The Company has no specific plan for the net proceeds of this Offering other
than to fund capital expenditures and for general working capital purposes. As a
consequence, the Company's management will have broad discretion over the
allocation of the proceeds for the foreseeable future. Pending any such uses,
the Company plans to invest the net proceeds in investment-grade,
interest-bearing securities. See "Use of Proceeds."
 
ANTI-TAKEOVER CONSIDERATIONS
 
    The Company's Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") authorizes the Board of Directors to issue,
without stockholder approval, up to 1,000,000 shares of Preferred Stock with
voting, conversion and other rights and preferences that could adversely affect
the voting power or other rights of the holders of Common Stock. In addition,
the Company will be subject to the provisions of Section 203 of the Delaware
General Corporation Law, which will generally prohibit the Company from engaging
in a "business combination" with an "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
interested stockholder, unless the business combination is approved in a
prescribed manner. The foregoing and other provisions of the Certificate of
Incorporation and the Company's By-laws, as amended (the "By-laws") and the
application of Section 203 of the Delaware General Corporation Law could have
the effect of deterring certain takeovers or delaying or preventing certain
changes in control or management of the Company, including transactions in which
stockholders might otherwise receive a premium for their shares over then
current market prices. See "Description of Capital Stock--Preferred Stock" and
"--Delaware Anti-takeover Statute."
 
SUBSTANTIAL DILUTION
 
    Purchasers of shares of Common Stock offered hereby will experience
immediate and substantial dilution in the net tangible book value of their
investment from the initial public offering price. Additional dilution will
occur upon exercise of outstanding options, warrants and preemptive rights. In
addition, Thomson is entitled to receive shares of Common Stock equal to 1% of
the Company's Common Stock outstanding upon the acceptance by the Company of
each of the next four $3.0 million of orders placed by Thomson with the Company
through May 1998. See "Dilution" and "Business--Strategic Relationships--
Thomson-CSF."
 
ABSENCE OF DIVIDENDS
 
    The Company has never paid any cash dividends on the Common Stock and does
not anticipate paying any cash dividends in the foreseeable future, but instead
intends to retain earnings, if any, for use in the Company's operations and in
the expansion of its business. See "Dividend Policy."

<PAGE>
                                USE OF PROCEEDS
 
    The net proceeds to the Company from this Offering are estimated to be
approximately $         ($      if the Underwriters' over-allotment option is
exercised in full), assuming an initial public offering price of $    per share
and after deducting underwriting discounts and commissions and estimated
Offering expenses.
 
    The Company anticipates that approximately $         million of the net
proceeds from this Offering will be used to fund capital expenditures,
investments in strategic suppliers, including the exercise of certain stock
purchase rights, and investments in potential international joint ventures
associated with NetSat. The remainder of the net proceeds will be used to fund
working capital requirements, increased selling and marketing efforts, increased
internal research and development expenses, start-up expenses related to NetSat,
and for general corporate purposes.
 
    Pending such uses, the net proceeds will be invested in short-term debt
instruments, certificates of deposit or direct or guaranteed obligations of the
United States.
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid any cash dividends on its capital stock
since inception and does not expect to pay dividends in the foreseeable future.
The Company presently intends to retain future earnings, if any, to finance the
expansion of its business. The payment of any cash dividends in the future will
depend on the Company's earnings, financial condition, results of operations,
capital needs, and other factors deemed pertinent by the Company's Board of
Directors, subject to laws and regulations then in effect.

and the authorization of additional shares of Common Stock and Preferred Stock,
$.001 par value (the "Preferred Stock") and (ii) on a pro forma as adjusted
basis to give effect to the sale by the Company of       shares of Common Stock
at an assumed initial public offering price of $         per share, after
deducting underwriting discounts and commissions and estimated Offering
expenses, and the application of the estimated net proceeds therefrom.

    $5.65 per share. At December 31, 1996, 1,995,000 shares of Common Stock were
    available for issuance under the Company's stock option plans. On February
    26, 1997, the Board of Directors authorized, subject to stockholder
    approval, an increase of 285,000 shares of Common Stock available for
    issuance under the Company's stock option plan. Also excludes 64,125 shares
    of Common Stock issuable upon exercise of warrants, all with an exercise

                                    DILUTION
 
    The pro forma net tangible book value of the Company as of December 31, 1996
was approximately $16.5 million or $2.88 per share of Common Stock. "Pro forma
net tangible book value per share" is equal to the Company's total tangible
assets less total liabilities, divided by the number of shares of Common Stock
outstanding and gives effect to the Stock Split, the Preferred Stock Conversion
and the exercise of a warrant on January 24, 1997 to purchase 106,901 shares of
Common Stock at an exercise price of $5.26 per share. After giving effect to the
sale by the Company of       shares of Common Stock in this Offering (at an
assumed initial public offering price of $         per share) and after
deducting the estimated underwriting discounts and Offering expenses, the pro
forma net tangible book value of the Company as of December 31, 1996 would have
been $         or $         per share of Common Stock. This represents an
immediate increase in pro forma net tangible book value per share of $
to existing holders and immediate dilution in pro forma net tangible book value
of $         per share to new investors. The following table illustrates the per
share dilution:

    The foregoing is based on the number of shares outstanding as of December
31, 1996 and assumes no exercise of any outstanding options or warrants. At
December 31, 1996, there were outstanding options to purchase an aggregate of
1,557,027 shares at a weighted average exercise price of $5.65 per share.
Additionally, on December 31, 1996 there were outstanding warrants which may be
exercised for up to 64,125 shares of Common Stock at a price of $8.07 per share.
Additional dilution will occur upon exercise of the outstanding warrants or
options. See "Management--1997 Stock Incentive Plan" and Notes 6 and 8 of Notes

    shipped but have not been accepted by the customer. The Company's backlog at
    any given time is not necessarily indicative of future period revenues. See

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
    THIS PROSPECTUS CONTAINS, IN ADDITION TO HISTORICAL INFORMATION,
FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S
ACTUAL RESULTS COULD DIFFER SIGNIFICANTLY FROM THE RESULTS DISCUSSED IN THE
FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH
DIFFERENCES INCLUDE THOSE DISCUSSED IN "RISK FACTORS" AS WELL AS THOSE DISCUSSED
ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
    The Company designs, assembles and installs satellite ground segment systems
and networks. In addition, it is currently in the early stages of expanding its
business to provide high-speed, satellite-delivered data communications
services, including Internet access, to areas of the world which lack the
terrestrial communication network infrastructure required to provide such
services on a cost-effective basis.
 
    The Company was founded in August 1994 and was a development-stage
enterprise for the period from its inception through June 30, 1995. During this
period it was involved in various start-up activities, including raising
capital, acquiring equipment, leasing office space, recruiting and training
personnel and developing its initial marketing efforts. The Company began
generating revenue during June 1995, and has grown rapidly since that date.
 
    Since the Company's inception, substantially all of the Company's revenue
has been generated by its satellite ground segment-related operations. Contracts
for these ground segment systems and networks have been in virtually all cases
fixed-price contracts. The period from contract award through installation of
ground segment systems and networks supplied by the Company generally requires
from three to 12 months. The Company uses the percentage of completion method of
accounting for contract revenues, upon the achievement of certain milestones.
Accordingly, most of the revenue from sales of products is typically recognized
when the product is shipped, with the balance recognized at the time of
acceptance by the customer. Revenues from providing services are recognized at
the time the service is performed. Costs of revenues are generally recorded
based on the relationship of the amount of projected final costs to the
percentage of revenue recorded for the specific contract. See Note 2 of Notes to
Consolidated Financial Statements.
 
    The Company's role in supplying a particular system or network may range
from designing systems and acquiring and installing the components required to
meet a customer's specific design specifications to the complete design and
engineering of the ground segment of a satellite communications network. The
profitability of any particular contract is affected significantly by: (i) the
extent to which the Company is called upon to perform relatively high
value-added design activities, (ii) whether the contract is awarded on a
negotiated basis or by competitive bid, (iii) the extent to which the system or
network can be implemented by replicating previously engineered products and
(iv) competitive factors. Generally, the lowest margins are experienced for
ground segment systems and networks built to customer-engineered specifications,
installed under a contract awarded through a competitive bidding process and
requiring a minimum of engineering by the Company. The highest margins generally
are experienced for engineering-intensive, value-added ground segment systems
and networks designed by the Company.
 
    The Company typically relies upon a small number of customers for a large
portion of its revenues. For example, approximately 43% and 17% of the Company's
revenues in fiscal 1996 and for the six months ended December 31, 1996,
respectively, were derived from sales to Hughes Network Systems. At December 31,
1996, $16.5 million, or approximately 61% of the Company's backlog, was
accounted for by a contract between the Company and A Sky B. The Company expects
that in the near term a significant portion of its revenues will continue to be
derived from one or a limited number of customers (the identity of whom may vary
from year to year) as the Company seeks to expand its business and its customer
base. The reduction, delay, or cancellation of orders from one or more of such
significant customers would have
 
                                       20
<PAGE>
a material adverse effect on the Company's business, financial condition and
results of operations. See "Risk Factors--Customer Concentration" and
"Business--Customers."
 
    Costs of revenues consist primarily of the costs of purchased material,
direct labor and related overhead expenses, project-related travel, living costs
and subcontractor salaries. Selling and marketing expenses consist primarily of
salaries and travel and living costs for sales and marketing personnel. Research
and development expenses consist primarily of salaries and related overhead
expenses paid to engineers. The Company also benefits from research and
development conducted by its strategic suppliers. See "Business--Research and
Development." General and administrative expenses consist of expenses associated
with the Company's management, accounting, contract and administrative
functions. The Company anticipates that selling and marketing, research and
development and general and administrative expenses will continue to increase
during the next several years due to expected increases in personnel and
expenses related to supporting the Company's expanding customer base.
 
    The Company and Thomson entered into an agreement in November 1995 under
which Thomson purchased 199,500 shares of Common Stock of the Company at $4.68
per share. Pursuant to this agreement, the Company is obligated to issue up to
an additional 5% of its Common Stock under the following conditions: 1% of the
then outstanding Common Stock upon acceptance of sales orders from Thomson
totalling $1.5 million, and 1% of the then outstanding Common Stock upon the
acceptance of each of four subsequent increments of $3.0 million of sales orders
from Thomson. This agreement is in effect until May 1998. Upon the issuance of
shares under this agreement, the Company recognizes sales and marketing expense
based on a price of $4.68 per share, the fair market value of the shares at the
date of the agreement. Such amounts are recorded initially in the balance sheet
as prepaid expenses until the related orders are recorded as revenue, at which
time such amounts are recorded in the statement of operations. In November 1995,
the Company issued 37,147 shares of Common Stock to Thomson under this
arrangement after receipt of sales orders totaling $1.5 million, resulting in
the recognition of $173,743 of selling and marketing expense during the six
months ended December 31, 1996. See "Dilution," "Business--Strategic
Relationships--Thomson-CSF" and Note 6 of Notes to Consolidated Financial
Statements.
 
    The Company consolidates the operating results of NetSat subject to the
minority interests relating to Hughes Network Systems' 19% and PolyVentures II,
Limited Partnership's ("PolyVentures") 2% investment in NetSat. For the six
months ended December 31, 1996, the minority interests in the operations of
consolidated subsidiary recorded was $275,000, the total amount of HNS' and
PolyVentures' capital contributions to NetSat. In the future (unless a party
other than the Company makes an additional capital contribution to NetSat), the
Company will consolidate 100% of NetSat's operating losses. If NetSat's
operations achieve profitability in the future, the Company would continue to
consolidate 100% of NetSat's operating results until such time as the amount of
profits otherwise attributable to Hughes Network Systems and PolyVentures would
have fully offset their proportionate share of NetSat's losses previously
recorded by the Company. In addition, Hughes Network Systems has the right,
until August 2001, to increase its equity interest in NetSat to 29% at nominal
cost.
 
    The Company currently accounts for its interests in its strategic supplier
partners and other investees using the cost method of accounting. To the extent
that the Company exercises any of its options to increase its equity interest in
such investee to greater than 20% and has the ability to exercise significant
influence over the operating and financial policies of the investee, the
Company's equity in the net income or loss of such investee would be accounted
for using the equity method of accounting. In the event that the Company
increases its interest in any of its investees such that it would be required to
convert to accounting for such interest using the equity method, generally
accepted accounting principles require that the Company's historical financial
statements be adjusted retroactively in a manner consistent with the accounting
for a step-by-step acquisition with respect to the results of any such investee
for the periods prior to using the equity method. See "Business--Strategic
Relationships."

    Due to the Company's development stage status prior to June 30, 1995, and
its rapid growth since that date, the comparison of its financial position and
results of operations from one period to another, as set forth below, is of
limited utility in predicting future results, and should be viewed with
considerable caution.

    SIX MONTHS ENDED DECEMBER 31, 1996 AND 1995
 
    REVENUES.  Revenues, which were derived from sales of ground segment systems
and networks, increased by $6.0 million, or 81.9%, to $13.3 million for the six
months ended December 31, 1996 from $7.3 million for the six months ended
December 31, 1995. The increase was primarily the result of an increase in the
number of shipments and/or completion of contracts from eight for the six months
ended December 31, 1995 to 24 for the six months ended December 31, 1996.
 
    COSTS OF REVENUES.  Costs of revenues increased by $5.5 million, or 92.4%,
to $11.5 million for the six months ended December 31, 1996 from $6.0 million
for the six months ended December 31, 1995. The increase was primarily due to
the increase in the shipment and/or completion of ground segment systems and
networks contracts. Costs of revenues as a percentage of revenues was 86.4% for
the six months ended December 31, 1996 compared to 81.7% for the six months
ended December 31, 1995.
 
    GROSS PROFIT.  Gross profit increased by $470,000 to $1.8 million for the
six months ended December 31, 1996 from $1.3 million for the six months ended
December 31, 1995. The increase was primarily due to the increase in the
shipment of ground segment systems and networks. Gross profit as a percentage of
revenues was 13.6% for the six months ended December 31, 1996 compared to 18.3%
for the six months ended December 31, 1995. Such decrease was due primarily to
an increase in orders awarded through a competitive bidding process, which
typically result in lower gross profit margins than negotiated contracts.

    SELLING AND MARKETING.  Selling and marketing expenses increased by
$605,000, or 75.9%, to $1.4 million for the six months ended December 31, 1996
from $796,000 for the six months ended December 31, 1995. The increase was
primarily due to the opening of marketing offices in Hong Kong and in Atlanta,
Georgia, the hiring of selling and marketing personnel for NetSat, commission
expense recorded in connection with the issuance of 37,147 shares of Common
Stock to Thomson as described above, and the increase in the number of bids and
proposals prepared by the Company. Selling and marketing expenses as a
percentage of revenues was 10.5% for the six months ended December 31, 1996
compared to 10.9% for the six months ended December 31, 1995.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses decreased by
$21,000, or 8.4%, to $229,000 for the six months ended December 31, 1996 from
$251,000 for the six months ended December 31, 1995 due to a decline in
development costs associated with customizable systems. Research and development
expenses as a percentage of revenues decreased to 1.7% for the six months ended
December 31, 1996 from 3.4% for the six months ended December 31, 1995.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
by $554,000, or 64.2%, to $1.4 million for the six months ended December 31,
1996 from $862,000 for the six months ended December 31, 1995, but decreased as
a percentage of revenues to 10.7% for the six months ended December 31, 1996
from 11.8% for the six months ended December 31, 1995. The increase in general
and administrative expenses resulted from personnel increases to service the
increasing customer base for the Company's ground segment business as well as
the hiring of NetSat administrative personnel.
 
    FISCAL YEARS ENDED JUNE 30, 1996 AND 1995
 
    REVENUES.  Revenues increased to $13.5 million for the fiscal year ended
June 30, 1996 from $72,000 for the year ended June 30, 1995 as a result of the
commencement of commercial operations.
 
    COSTS OF REVENUES.  Costs of revenues increased to $11.2 million for the
fiscal year ended June 30, 1996 from $58,000 for the fiscal year ended June 30,
1995 as a result of the commencement of commercial operations.
 
    GROSS PROFIT.  Gross profit increased to $2.2 million for the fiscal year
ended June 30, 1996 from $14,000 for the fiscal year ended June 30, 1995. The
increase was primarily due to the commencement of commercial operations and the
shipment of ground segment systems and networks.
 
    SELLING AND MARKETING.  Selling and marketing expenses increased to $1.9
million for the fiscal year ended June 30, 1996 from $346,000 for the fiscal
year ended June 30, 1995 as a result of the first full year of commercial
operations.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses were $712,000
for the fiscal year ended June 30, 1996. There were no research and development
expenses for the fiscal year ended June 30, 1995. Research and development
expenses in fiscal 1996 were related primarily to development of the Company's
customizable systems.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
to $1.9 million for the fiscal year ended June 30, 1996 from $772,000 for the
fiscal year ended June 30, 1995. This increase was primarily attributable to
increases in costs of hiring additional personnel to support the Company's
expanding customer base.

    The Company may in the future experience significant quarter to quarter
fluctuations in its results of operations, which may result in volatility in the
price of the Company's Common Stock. Quarterly results of operations may
fluctuate as a result of a variety of factors, including the timing of the
initiation and completion of contracts, the demand for the Company's products
and services, the introduction of new or
 
                                       24
<PAGE>
enhanced products and services by the Company or its competitors, market
acceptance of new products and services, the mix of revenues between
custom-built satellite communications systems and networks designed for its
customers and standard installations provided to its customers, the growth of
demand for Internet infrastructure-based products and services in developing
countries, the timing of significant marketing programs, the extent and timing
of the hiring of additional personnel, competitive conditions in the industry
and general economic conditions. Due to the foregoing factors, it is likely that
in one or more future quarters the Company's operating results will be below the
expectations of public market analysts and investors. Such an event could have a
material adverse effect on the price of the Company's Common Stock.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company has financed its operations to date primarily from the sale of
equity securities and, to a lesser degree, from stockholder loans. Through
December 31, 1996, the Company raised approximately $19.8 million of net
proceeds through private offerings of its Common Stock and Convertible Preferred
Stock. The Company received net proceeds of $4.2 million from sales of Common
Stock in private offerings during the period from August 17, 1994 (inception) to
June 30, 1995, $4.4 million from sales of Common Stock and Convertible Preferred
Stock in private offerings during the fiscal year ended June 30, 1996 and $11.2
million from the sale of Convertible Preferred Stock in private offerings
completed during the six months ended December 31, 1996. In addition, the
Company's chief executive officer lent the Company $315,000 in October 1994,
which was repaid in full in January 1997, and $80,700 during fiscal 1995, of
which $60,000 was repaid during fiscal 1995 and $20,700 was repaid during fiscal
1996. See "Certain Transactions."
 
    At December 31, 1996, the Company had working capital of $11.3 million,
including cash and cash equivalents of $9.6 million, restricted cash of $1.6
million and accounts receivable of $7.8 million, offset by $6.3 million in
accounts payable and $1.6 million in accrued expenses.
 
    The Company has experienced negative cash flow from operations since its
inception. Net cash used in operating activities for the periods from inception
to June 30, 1995 and the fiscal year ended June 30, 1996 was $454,000 and $2.5
million, respectively. The principal factor contributing to the negative
operating cash flow during the period from inception to June 30, 1995 was the
net loss from operations for this period of $1.1 million. This loss was offset
in part by an excess of approximately $387,000 of accounts payable over the
value of inventory at the end of the period. This excess reflects the fact that
the Company normally acquires inventory only against specific customer
contracts. As a result, a portion of such inventory is delivered and revenue
accrued more quickly than payment for such inventory is required by normal
commercial terms. For the fiscal year ended June 30, 1996, the principal
contributor to the negative cash flow, in addition to the net loss of $2.2
million, was an increase in accounts receivable of approximately $1.9 million as
deliveries were made against the underlying contracts. This negative cash flow
was offset in part by reductions in inventory of approximately $664,000,
increases in operating liabilities (reflecting a continued expansion of
operations) and the use of stock to pay certain compensation expenses.
 
    Management anticipates that NetSat will experience negative cash flow for at
least the next several years as a result of capital investment required for
construction of its hub facility in Hauppauge, New York, development of its
planned initial operations in Russia, Brazil and Eastern Europe and initial
losses from operations. In order to limit the capital requirements for startup
of operations in Eastern Europe, current plans call for NetSat to use the
services of a hub facility located in Germany and owned by Hughes Olivetti
Telecom Limited, an affiliate of Hughes Network Systems.
 
    Several factors had a major effect on the Company's liquidity during the six
months ended December 31, 1996. First, revenues increased substantially as a
result of a significant increase in contract deliveries, particularly during
December. Revenues for the six-month period nearly equaled those of the
 
                                       25
<PAGE>
entire fiscal year ended June 30, 1996. The higher revenues increased the
Company's working capital needs, as accounts receivable increased by
approximately $5.8 million during the six-month period. Offsetting the increased
accounts receivable were an increase in accounts payable of approximately $3.5
million and accrued expenses of approximately $1.1 million, both reflecting
costs incurred in performing the contracts and receipt of substantial progress
payments against contracts not yet completed of approximately $1.7 million.
Because the Company records progress payments as an offset to inventory, the
approximately $1.3 million decrease in net inventory during the six-month period
is lower than might be expected based on the increased level of activity.
Inventory levels may be expected to increase as work proceeds on these
contracts.
 
    The second factor affecting liquidity during the six-month period was the
Company's investment activities. The Company increased its investment in its
strategic suppliers by approximately $835,000 during the period and purchased
approximately $400,000 in additional computer and test equipment. In addition,
the Company purchased a new office and assembly facility for approximately $2.6
million in cash, which the Company expects will require an additional
expenditure of $2.5 million for improvements before it is ready for occupancy.
The Company intends to seek financing for the facility and improvements through
third parties.
 
    The third major factor affecting liquidity was the completion of a private
offering of Convertible Preferred Stock at the close of the six-month period.
Net proceeds of this offering were approximately $11.0 million leaving the
Company with cash and cash equivalents at the end of the period of approximately
$9.6 million.
 
    The Company has incurred losses since its inception and therefore has not
been subject to federal income taxes. Through December 31, 1996, the Company,
for income tax purposes, has generated net operating loss carryforwards of
approximately $3.1 million which may be available to reduce future taxable
income and future tax liabilities. These carryforwards begin to expire in the
years 2010 through 2012. The Tax Reform Act of 1986 provides for an annual
limitation on the use of net operating loss carryforwards (following certain
ownership changes) that could significantly limit the Company's ability to
utilize these carryforwards. Upon the completion of this Offering, the exercise
of the over-allotment option or the subsequent exercise of option or warrants or
in connection with other future sales of equity, the Company's ability to
utilize the aforementioned carryforwards to reduce future taxable income and tax
liabilities may be limited. Additionally, because the United States tax laws
limit the time during which these carryforwards may be applied against future
taxes, the Company may not be able to take full advantage of these attributes
for federal income tax purposes.
 
    The Company is currently in negotiations with a bank with respect to a $5.0
million credit facility.
 
    The Company's future capital requirements will depend upon many factors,
including the extent to which it is able to locate additional strategic
suppliers in whose technology it wishes to invest, the success of the Company's
marketing efforts in both the satellite ground segment and Internet services
fields, the nature and timing of customer orders and the extent to which it must
conduct research and development efforts internally. Based on current plans, the
Company believes that its existing capital resources together with the net
proceeds of this Offering will be sufficient to meet its capital requirements
for at least the next 18 months.

OVERVIEW
 
    The Company designs, assembles and installs satellite ground segment systems
and networks which support a wide range of satellite communications
applications, including fixed, mobile and direct broadcast services as well as
certain military applications. The Company's customers include prime
communications infrastructure contractors, government-owned PTTs, other
telecommunications carriers, producers and distributors of news and
entertainment content and other corporations. The Company's ground segment
systems typically consist of an earth station, which is an integrated system
designed to transmit and receive signals to and from satellites, together with
ancillary subsystems. The Company's ground segment networks are typically
comprised of two or more ground segment systems communicating with a satellite
and interconnected with a terrestrial network. Since the Company commenced
operations in August 1994, it has completed the installation of 35 ground
segment systems and networks for 24 customers in 18 countries.
 
    During the six months ended December 31, 1996, the Company booked $28.8
million in contract orders and at December 31, 1996 had a backlog of $27.1
million of contract orders. The Company believes that its historical performance
and its ability to compete successfully in the future are based on its unique
combination of competitive advantages which include: (i) an experienced
management group with extensive technological and engineering expertise, (ii)
the proven ability to meet the complex satellite ground segment requirements of
its customers in diverse political, economic and regulatory environments in
various locations around the world and (iii) its ability to identify, develop
and maintain strategic relationships with developers and suppliers of
leading-edge technologies which enhance performance, reduce costs and broaden
the applications of the Company's ground segment systems and networks.
 
    The Company has recently established a subsidiary, NetSat, to develop
service revenues by providing high-speed, satellite-delivered data
communications to developing markets worldwide. In order to accomplish this
objective, NetSat intends to leverage: (i) the Company's expertise in satellite
ground segment system and network implementation, (ii) extensive management
experience in providing satellite-delivered communications services, (iii) the
knowledge and capabilities of local market strategic partners and (iv) DirecPC
and Personal Earth Station technology developed and owned by Hughes Network
Systems. Any use by NetSat of HNS' DirecPC technology will require the grant of
a license from HNS to NetSat. NetSat currently is pursuing joint ventures with
local partners in Russia and Brazil to market low-cost, high-speed satellite
Internet access services, as well as intranet services, to corporate,
educational and government customers who have limited or no access to
terrestrial network infrastructure capable of supporting the economical delivery
of such services.
 
INDUSTRY BACKGROUND
 
SATELLITE COMMUNICATIONS
 
    MARKET STRUCTURE
 
    Satellite communications systems are comprised of satellites (the "space
segment") and ground-based transmission and reception systems (the "ground
segment"). The space segment consists of one or more satellites in earth orbit
which typically provide continuous communications coverage over a wide
geographic area. Satellites typically contain multiple transponders, each
capable of independently receiving and transmitting one or more signals to or
from multiple users simultaneously. The ground segment consists principally of
one or more earth stations, which provide a communications link to the end user
either directly or through a terrestrial network. An earth station is an
integrated system consisting of antennas, radio signal transmitting and
receiving equipment, modulation/demodulation equipment, monitor and control
systems and voice, data and video network interface equipment.
 
                                       27
<PAGE>
    Satellite communications industry participants include: (i) designers,
manufacturers and integrators of ground segment products, systems and networks,
(ii) communications service providers, which may or may not own the actual
satellites used for transmission and (iii) designers, manufacturers and
operators of satellites. The Company has participated principally in the ground
segment systems and networks portion of the market and has recently expanded
into the satellite-delivered data communications services market through its
NetSat subsidiary.
 
    MARKET SIZE
 
    According to FCC estimates, providers of commercial satellite-delivered
communications services generated approximately $13.8 billion in revenues in
1995 and this amount is expected to grow at a compound annual rate of
approximately 21% through the year 2000 to approximately $37.0 billion. The
Company believes that the historic and expected growth in its addressable ground
segment markets has been and will continue to be driven by, among other things,
the growth of satellite-delivered communications services.
 
    SATELLITE GROUND SEGMENT.  Based on industry sources, the markets for ground
segment systems and networks in which the Company competes had aggregated
revenues of approximately $1.6 billion in 1996 and are projected to grow at a
compound annual rate of approximately 11% to revenues of approximately $2.5
billion by the year 2000. These data do not include estimates for revenues of
military-tactical systems, custom networks, ground segment management systems
and dedicated Internet access products, each of which is a market to which the
Company targets its ground segment systems and networks.
 
    SATELLITE-DELIVERED DATA COMMUNICATIONS SERVICES.  Through NetSat, the
Company participates in the satellite-delivered data communications segment of
the overall satellite-delivered communications services market. Although there
are currently no reliable data available on the market for satellite-delivered
Internet and intranet applications in developing countries, the Company believes
such market has potential for rapid growth. The Company bases this belief on the
increasing use of Internet and intranet applications in developing markets,
together with the relatively undeveloped terrestrial infrastructure in such
markets. The FCC has estimated that the worldwide satellite-delivered data
communications market (including Internet and intranet applications) accounted
for revenues of approximately $1.3 billion in 1995 and projects that such
worldwide market will grow at a compound annual growth rate of 26% to revenues
of approximately $4.2 billion in the year 2000.
 
    SATELLITE SERVICE APPLICATIONS
 
    Satellites provide a number of advantages over terrestrial facilities for
many high-speed communications service applications. First, satellites enable
high-speed communications service where there is no suitable terrestrial
alternative available or where the terrestrial alternative is inadequate.
Second, unlike the cost of terrestrial networks, the cost to provide services
via satellite does not increase with the distance between sending and receiving
stations. Finally, in contrast to the installation of fiber optic cable which is
expensive, time consuming and requires obtaining rights-of-way, satellite
networks can be rapidly installed, upgraded and reconfigured. The three
principal categories of satellite communications service applications are: (i)
fixed satellite services, (ii) mobile satellite services and (iii) direct
broadcast services.
 
    FIXED SATELLITE SERVICES.  Fixed satellite services provide point-to-point
and point-to-multipoint satellite communication of voice, data and video between
fixed land-based earth stations. The introduction of high-power satellites has
created additional growth within the fixed satellite services segment by
enabling the use of smaller, less costly earth stations, such as very small
aperture terminals ("VSATs"), for applications such as corporate data networks,
Internet access and rural telephony. The Company believes that the fixed
satellite services segment will continue to experience rapid growth due to the
expansion of VSAT applications and the planned implementation of new
high-capacity, high-power Ka-band (20-30
 
                                       28
<PAGE>
GHz) systems within the next several years. The future Ka-band services are
expected to expand the number of applications provided directly to the home and
are expected to reduce significantly the cost of such services. These systems
offer the additional bandwidth needed for emerging multimedia services that
combine voice and video transmissions, as well as Internet access, expanded
telephony services, and computer networking.
 
    MOBILE SATELLITE SERVICES.  Mobile satellite services, which operate between
fixed gateway earth stations and mobile user earth stations (terminals), provide
mobile voice and data transmission capability on land, sea and air. New mobile
satellite services are being developed using low, medium and geostationary
orbiting satellite systems that are designed to bring more extensive coverage
and circuit reliability for mobile telephone and data services to underserved
populations throughout the world.
 
    DIRECT BROADCAST SERVICES.  Direct broadcast satellite services provide a
direct transmission link from high-power satellites to customers over a wide
geographic area. Technology which has been successfully deployed by Thomson,
Hughes Network Systems and others for direct-to-home television services is now
being applied to direct broadcast data services, including Internet and intranet
access.
 
DATA COMMUNICATIONS AND THE INTERNET
 
    The data communications services market is comprised currently of common
carrier data network services, corporate business networks and emerging
applications such as Internet and intranet services. The Company believes that
Internet and intranet services will comprise a significant portion of data
communications services used in developing countries, and that the growth of
data communications services in these regions will rely on satellite
communications to a significant extent.
 
    THE INTERNET
 
    The Internet is a global network of millions of interconnected computers and
computer networks that allow businesses, other organizations and individuals to
communicate electronically, distribute and receive information and conduct
commerce. Advances in technology, low-cost Internet access and an increasing
corporate reliance on distributed information environments has fueled the rapid
growth of the Internet. Much of the recent growth in Internet use by businesses
and individuals has been driven by the emergence of the World Wide Web (the
"Web"), a network of servers and information available on the Internet. The Web
enables users to find and retrieve vast and diverse quantities of information on
the Internet in a consistent, easy-to-use manner that makes the underlying
complexities transparent to the user. Recently introduced applications permit
the user to carry on a conversation, complete with video, with a user located
anywhere in the world for the price of a local call.
 
    The utility of the Internet as a global communications network enabling
millions of users worldwide to access information in real-time is dependent upon
the existence of a communications infrastructure which can accommodate the rapid
and reliable transmission of such information. Today, much of the world lacks
not only the sophisticated optical fiber and digital switching infrastructure
required for the high-speed transmission of data over the Internet, but also the
basic telephone networks to accommodate low-speed data communication over
traditional analog facilities. Due to the high costs associated with the
installation of wireline infrastructures capable of the reliable transmission of
data at higher speeds and with better quality, the Company believes that the
development of a communications infrastructure in much of the world, and the use
of the Internet both by individuals and as a viable commercial tool, will in
large part depend upon the rapid installation of wireless and satellite
communications systems.
 
    CORPORATE INTRANETS
 
    The low-cost client/server tools which have been developed for the Internet
offer compelling support for the creation of corporate "intranets," which are
private data networks that provide employees with easy access to corporate
databases. The benefits of applying Internet technology to private corporate
data
 
                                       29
<PAGE>
networks include the lower cost of implementation, standardized user interfaces,
lower training and support costs, platform independence, and the ease of
interfacing to "legacy" mainframe databases. The benefits associated with
corporate migration to these Internet tools have created a rapidly growing
market in the United States and other developed markets where relatively
inexpensive data communications have been available. An industry source
estimates that revenues from the corporate intranet market will exceed the
revenues attained from the Internet market by a ratio of 2:1 by the year 1999.
 
    The Company believes that the use of satellite communications technology
which may be used to bring both the Internet and corporate intranets to nations
that are developing their telecommunications infrastructure will help those
nations rapidly improve their education, access to medical information, commerce
and overall communications.
 
GROWTH DRIVERS
 
    The Company believes that the growth projected by third parties in the
satellite communications industry will be driven principally by the following
major factors: (i) global deregulation and privatization of government-owned
monopoly telecommunications carriers, (ii) rapidly growing worldwide demand for
communications services in general, including data communications services over
the Internet and corporate intranets, (iii) the relative cost-effectiveness of
satellite communications for many applications and (iv) technological
advancements which broaden applications for and increase the capacity in both
satellite and terrestrial networks.
 
    DEREGULATION AND PRIVATIZATION.  Rapid deregulation and privatization, and
the implementation of governmental policies aimed at developing modern
telecommunications infrastructure, are occurring globally, as countries seek the
economic benefits of enhanced and expanded telecommunications services. Through
deregulation and privatization, governments are stimulating the development of
competitive telecommunications services in the private sector. These actions
have placed communications carriers under increasing pressure to achieve greater
efficiencies and to offer their services to broader customer bases at more
competitive prices, leading to an increase in capital investment. In addition,
the Company believes that the recent World Trade Organization proposal which
will provide U.S. and foreign companies with market access to a variety of
telecommunications services and allow foreign ownership of telecommunication
companies will lead to additional increased capital investment in the worldwide
telecommunications market.
 
    GROWING WORLDWIDE DEMAND FOR COMMUNICATIONS SERVICES.  Factors contributing
to the growing demand for communications services include worldwide economic
development, governmental policies aimed at improving the telecommunications
infrastructure in developing countries and the increasing globalization of
commerce. In addition to the growth in developing markets, the terrestrial
infrastructure in developed countries is evolving to support the growing demand
for higher bandwidth services in response to the needs of businesses to
communicate with customers and employees located around the world and to the
growing acceptance of the Internet and multimedia applications as both
productivity-enhancing tools and consumer products. The Company expects demand
for these kinds of higher bandwidth services to grow in developing countries as
well. The International Telecommunications Union forecasts that the number of
telephone lines in developing countries will grow at a compound annual growth
rate of 17% per year through the year 2000, compared to 5% per year in the same
period for developed nations. The Company believes that global network
infrastructure development will require significant reliance upon satellite
communications because satellite-delivered communications services can be
implemented quickly and deliver flexible high-speed transmission capacity at
relatively low cost over large geographic areas.
 
    RELATIVE COST-EFFECTIVENESS OF SATELLITE COMMUNICATIONS.  The relative
cost-effectiveness of satellite communications compared to terrestrial solutions
for many applications is a major factor driving the growth of satellite
communications in areas with rapidly growing telecommunications infrastructures
such
 
                                       30
<PAGE>
as the Asia-Pacific region and the former Soviet Union. The vast geographic
areas to be covered, where population concentrations are separated by large
distances, require a technology whose cost and speed of implementation is
relatively insensitive to distance. Unlike the cost of terrestrial networks, the
cost to provide services via satellite does not increase with the distance
between sending and receiving stations. A single satellite can be configured to
deliver both broad beams that cover entire regions and narrow spot beams that
cover only areas of high population or traffic density.
 
    TECHNOLOGICAL ADVANCES.  Technological advances which increase the capacity
of a single satellite and/ or increase the number of potential applications of
its available bandwidth reduce the overall cost of a system or the service it
delivers. This increases the number of potential end users for the services and
expands the available market. Recent technological developments which make
satellite solutions increasingly competitive in cost and performance with
terrestrial-based networks, or as a viable alternative solution where
terrestrial services are not feasible, include:
 
    - BANDWIDTH ON DEMAND -- allows the satellite transponder bandwidth to be
      allocated dynamically as user needs require. Excess bandwidth capacity is
      returned to a "pool" of bandwidth that can then be accessed by other
      users.
 
    - DIGITAL TECHNOLOGY -- allows compression of data to communicate more
      information at lower costs using less bandwidth. Digital compression
      technology, when applied to international voice, data and video
      transmission by satellite, increases several fold the capacity of
      satellite transponders.
 
    - HIGH-POWER SATELLITES -- provide a signal powerful enough to deliver
      reception over a large geographic area and reduce the size, and
      consequently cost, of the ground-based receiving and transmitting
      antennas. High-power satellites, coupled with advanced digital processing
      receivers, allow transmission of high-quality television programming and
      high-speed data to the home with antennas of less than 21 inches in
      diameter.
 
    - SPOT-BEAM TECHNOLOGY -- narrowly focuses a satellite-delivered signal on
      the receiving antenna and reduces the total power requirements in the
      satellite, enabling an increase in a satellite's circuit capacity without
      a corresponding increase in weight, associated equipment and launch costs.
      Spot-beam technology, combined with an antenna for wide area coverage, may
      be used to provide local and national television programming
      simultaneously from a single geostationary satellite.
 
    - ONBOARD PROCESSING -- provides the ability to switch circuits on the
      satellite rather than on the ground. By building a "switch in the sky,"
      the cost of implementing telecommunications infrastructure may be reduced,
      facilitating the implementation of applications such as mobile telephony
      via satellite and future direct-to-home data, video and voice services.
 
GSI COMPETITIVE ADVANTAGES
 
    The Company believes that it is well positioned to capitalize on the
increasing demand for satellite ground segment systems and networks and
satellite-delivered data communications services and that its future success in
these markets will be based upon its ability to leverage its unique combination
of competitive advantages that have led to its historical achievements and its
favorable industry reputation. These competitive advantages include: (i) an
experienced management group with extensive technological and engineering
expertise, (ii) the proven ability to meet the complex satellite ground segment
requirements of its customers in diverse political, economic and regulatory
environments in various locations around the world and (iii) the ability to
identify, develop and maintain strategic relationships with developers and
suppliers of leading-edge technologies which enhance the performance, reduce
costs and broaden the applications of the Company's ground segment systems and
networks.

GSI BUSINESS STRATEGY
 
    The Company's business strategy is to expand its market share in its ground
segment systems and networks business, improve its profitability, and create
opportunities to capture recurring service revenues. The Company intends to
execute this strategy by: (i) targeting communication infrastructure development
opportunities worldwide, (ii) focusing on high margin engineering-intensive
system and network projects, (iii) developing strategic customer relationships,
(iv) developing strategic supplier relationships and (v) entering the data
communications services business through NetSat.
 
TARGET INFRASTRUCTURE DEVELOPMENT OPPORTUNITIES
 
    The Company primarily targets developing markets which it believes will
account for a significant portion of the growing demand for ground segment
systems and networks because these markets typically lack terrestrial
infrastructure adequate to support increasing demand for domestic and
international communications services. In addition, in developed countries the
Company targets ground segment infrastructure development projects for emerging
satellite communications applications such as direct broadcast and future
Ka-band frequencies. The Company has developed an international sales and
marketing organization focused on identifying opportunities for the Company and
on developing key sourcing relationships. In order to increase its access to
project opportunities and limit its exposure to the political and commercial
complexities of doing business in foreign countries, the Company intends to
continue to pursue international opportunities primarily in partnership with
strong local companies or as a subcontractor to larger communications services
and infrastructure providers. Most of the Company's revenues are derived from
sales to customers outside the United States. Revenues from foreign sales
accounted for 21.8% and 58.6% of total revenues in fiscal year 1996 and the six
month period ended December 31, 1996, respectively.
 
FOCUS ON ENGINEERING-INTENSIVE SYSTEM AND NETWORK PROJECTS
 
    The Company seeks to focus its technological expertise on high value-added
system and network projects which require engineering-intensive design and
implementation. This emphasis positions the Company to earn higher gross margins
through the delivery of innovative, cost-effective solutions to customer
performance requirements that are typically priced on a negotiated basis, as
opposed to typically lower-margin competitive bid projects. In addition, the
Company often benefits from the research and design phase of its more complex
projects through the development of proprietary products, systems and
technologies that can be applied cost-effectively to future projects and which
provide the Company with a competitive advantage.
 
DEVELOP STRATEGIC CUSTOMER RELATIONSHIPS
 
    The Company seeks to build close relationships with customers for whom it
can provide complementary engineering skills by working as part of their system
development teams. A key objective of this strategy is to obtain this business
on a negotiated basis, rather than through the competitive bidding process,
which is likely to carry a lower margin. To date, the Company has developed
strategic relationships with two of its customers: Hughes Network Systems and
Thomson. The Company sought the establishment of these relationships based on
these customers' abilities to: (i) generate significant potential revenues for
the Company, (ii) provide access to a large number of potential business
opportunities as a result of their size and global operations and (iii) provide
access to complementary technologies and expertise that could serve as
competitive advantages for the Company. At January 31, 1997, Hughes Network
Systems and Thomson owned equity interests in the Company of 3.7% and 4.9%,
respectively. In addition, Hughes Network Systems owns a 19% equity stake in
NetSat, with an option to increase this position to 29%.
 
                                       32
<PAGE>
DEVELOP STRATEGIC SUPPLIER RELATIONSHIPS
 
    The Company seeks to establish strategic relationships with suppliers that
it believes are in a unique position to supply products or services which will
improve the Company's competitive position in one or more of the markets which
it serves. In certain cases, the Company seeks to strengthen such relationships
by investing in such suppliers, and has, through December 31, 1996, made equity
investments of an aggregate of approximately $835,000 for minority equity stakes
of approximately 19%, 5% and 15% in Shiron Satellite Communications (1996) Ltd.
("Shiron"), C-Grams Unlimited, Inc. ("C-Grams") and Armer Communications
Engineering Services, Inc. ("Armer"), respectively. The strategic supplier
relationships with Shiron and C-Grams enable the Company to outsource a
significant portion of its research and development costs and gain access to
advanced technology while preserving the independence to select the best
products and technologies to deliver to its customers on any particular project.
The relationship with Armer allows the Company preferred access to quality field
engineering and installation resources. The Company intends to continue to
pursue additional strategic supplier relationships on a selective basis.
 
CREATE RECURRING SERVICE REVENUE OPPORTUNITIES
 
    The Company seeks to capture recurring revenues by providing data
communications services. The initial application of this strategy is the
Company's NetSat subsidiary, formed in alliance with Hughes Network Systems, to
provide satellite-delivered data communications services such as Internet
access, intranet applications and business data applications in developing
countries, using HNS' low-cost, high-speed Personal Earth Station and DirecPC
Terminal technology. The Company's strategy for implementing this objective
through NetSat includes the following major elements:
 
    MARKET THROUGH JOINT VENTURES AND STRATEGIC RELATIONSHIPS.  NetSat intends
to form joint ventures with strategic partners located in local markets around
the world which are expected typically to handle marketing, distribution and
support of the NetSat Direct and DirecPC products and would typically provide
transmission, content delivery, billing and customer service functions. The
Company anticipates selecting local market partners based upon their in-region
marketing experience, knowledge of the local regulatory environment, operating
licenses, existing customers, established business organizations and other
important elements that the Company believes will help support the success of
the venture. The Company is currently providing services in certain Eastern
European countries pursuant to a value-added reseller agreement with Hughes
Olivetti Telecom Limited ("HOT"), a joint venture between Ing. C. Olivetti & C.,
S.p.A. and an affiliate of Hughes Network Systems, and is pursuing joint
ventures with local partners in Russia and Brazil.
 
    SEEK MULTIPLE REVENUE SOURCES.  Through NetSat and its potential joint
venture affiliates, the Company intends to generate revenue from multiple
sources, including the sales of terminal equipment to potential subscribers, the
transmission of data via satellite, the provision of Internet connections and
incidental services such as domain name service, and the development and
delivery of custom content for specific customer groups.
 
    TARGET MULTINATIONAL CUSTOMER BASE.  NetSat intends to establish a diverse,
multinational customer base by designing innovative Internet, intranet and
business data service solutions for corporations, governments and educational
institutions in countries with rapidly growing telecommunications infrastructure
requirements. NetSat plans to apply the same satellite-delivered technology
which it uses for Internet access to meet the communication needs of corporate
users in such countries in support of their intranet requirements.

GSI GROUND SEGMENT SYSTEMS AND NETWORKS
 
    The Company designs, assembles and installs ground segment system and
network solutions for the complex and changing communications requirements of
its customers. The Company's ground segment systems typically consist of an
earth station and ancillary subsystems such as microwave links for back-haul of
traffic to a central office or generators for emergency power restoral. An earth
station is an integrated system consisting of antennas, transmitting and
receiving equipment, modulation/demodulation equipment, monitor and control
systems and voice, data and video network interface equipment. The Company's
ground segment networks are typically comprised of two or more ground segment
systems interconnected with a satellite and/or terrestrial communications
network. The Company's customizable systems may be sold separately as
stand-alone ground segment systems or may be used as modular building blocks to
be integrated into a complete ground segment system or network. The Company
believes that this modular approach allows it to engineer its ground segment
systems and networks to serve client-specific traffic and service requirements
rapidly, cost-effectively and efficiently.
 
CUSTOMIZABLE SYSTEMS
 
    CURRENTLY AVAILABLE CUSTOMIZABLE SYSTEMS
 
    FAMILY OF STANDARD INTELSAT EARTH STATIONS. This family of earth stations,
which is used primarily for international voice, data and video circuit trunking
and as gateways for domestic networks using the International Telecommunications
Satellite Organization ("Intelsat") system, is targeted principally at PTTs and
other common carriers. The family consists of earth stations of varying sizes
and capacities, all of which conform to Intelsat specifications. The Intelsat
Standard A earth stations, which have the highest capacity, feature antennas
ranging from 13 to 21 meters in diameter, high-power amplifiers from 700 to
3,000 watts, radio frequency converters and related electronics, modems and a
UNIX or Microsoft Windows NT based monitoring and control system. Available
options include power monitor systems, de-icing equipment, uninterruptible power
system/backup generators and equipment shelters. The Company has designed and
installed Intelsat Standard A earth stations in China, Korea, Kuwait, Malaysia,
the United Kingdom and the United States. The Company typically sells these
Intelsat Standard A earth stations at prices ranging from approximately $1.0
million (13-meter antenna) to approximately $2.0 million (21-meter antenna). The
Company is able to provide smaller, lower capacity earth stations that conform
to Intelsat specifications by customizing its modular building block or
commercial terminal families of earth stations described below.
 
    MODULAR BUILDING BLOCK (MBB) EARTH STATION.  These earth stations are
incorporated in point-to-point data links and hubs for VSAT and Demand Assigned
Multiple Access ("DAMA") networks, and are typically used as gateways for
corporate, common carrier and government networks. These earth stations can also
be configured to conform to the applicable standards of Intelsat and other
satellite systems. Earth stations constructed using MBBs require minimal site
preparation and can be installed rapidly and cost-effectively due to their
modular construction. Antenna sizes range from 4.5 to 9 meters, with high-power
amplifiers ranging from 50 to 700 watts. Generally, all electronics are housed
in a single building mounted rack. Available options include de-icing equipment,
tracking equipment, uninterruptible power system/ backup generators and
equipment shelters. To date, the Company has designed and installed MBB earth
stations in Brazil, India, Indonesia, Pakistan, Russia, Thailand and the United
States. The Company typically sells these earth stations at prices ranging from
approximately $250,000 to $600,000.
 
    COMMERCIAL TERMINAL FAMILY (CTF).  This family of earth stations, which
encompasses a range of general purpose, low-cost antenna-mounted earth stations,
is used primarily for data, voice or video transmissions from commercial or
government premises, and are principally targeted at corporate, common carrier
and government networks. These earth stations can also be configured to conform
to the applicable standards of Intelsat and other satellite systems. Antenna
sizes range from 1.2 to 9.3 meters, with high-power amplifiers ranging from 16
to 400 watts. Generally, all radio frequency electronics are
 
                                       34
<PAGE>
housed in weatherproof enclosures mounted on the antenna. To date, the Company
has designed and installed CTF earth stations in India, Korea, Russia and the
United States. The Company typically sells these earth stations at prices
ranging from approximately $100,000 to $300,000.
 
    MILITARIZED TRIBAND FLY-AWAY EARTH STATION FAMILY.  This family of triband
tactical earth stations is used for military communications applications and is
targeted principally at major defense contractors. These earth stations
typically use a 2.4 meter antenna, are highly transportable, and are designed to
be mounted on a pallet on military vehicles or air-dropped into a combat
environment. The pallet-mounted earth station features an automatic antenna
pointing and multichannel capability. These militarized earth stations are able
to perform under extreme conditions in the military tactical environment and
offer multiband capability: C-band (4-6 GHz), X-band (7-8 GHz) or K-band (12-17
GHz). The Company has sold one of each configuration of this earth station to
Thomson to be used as demonstration models incorporated into military
communications systems currently marketed by Thomson. Prices for these systems
range from approximately $250,000 to $1.0 million, depending on the
configuration.
 
    DIGITAL FLY-AWAY EARTH STATIONS.  This group of earth stations is primarily
used for emergency communications and news gathering and is comprised of highly
transportable, modular earth stations designed to be quickly deployed and
installed anywhere in the world. Antenna sizes range from 1.2 to 2.4 meters,
with high-power amplifiers up to 350 watts. All components are mounted in
separate cases which are small enough to be easily transported by commercial
carrier. Additional system availability can be achieved through the addition of
redundant modules for critical components. Since these units may be operated in
a variety of harsh environments, the Company conducts environmental stress
screening tests on these components for enhanced reliability. To date, the
Company has sold one digital fly-away earth station to a customer in Portugal.
The Company markets these earth stations at prices ranging from approximately
$150,000 to $600,000.
 
    EARTH STATION MANAGEMENT SYSTEMS.  The Company's earth station systems
typically employ monitor and control software for system maintenance developed
either by the Company or by its strategic supplier, C-Grams. This software
permits the station operator to monitor and control the status of each
electronic equipment component at the station from a remote location and to
receive immediate failure reports and analysis. The Company also offers database
applications to integrate maintenance and operational functions, thereby
reducing operating costs. The price of this software varies substantially and is
typically included in the price of the system or network provided by the
Company.
 
    CUSTOMIZABLE SYSTEMS UNDER DEVELOPMENT
 
    COMPACT DIGITAL EARTH STATION FAMILY.  This family of earth stations is
designed to be used principally to provide limited capacity (up to T1/E1 data
rates) to areas with limited or no telecommunications infrastructure. These
digital earth stations will integrate radio frequency and baseband components
into one antenna-mounted package. These earth stations feature a multiband
capability and a proprietary L-band (1 to 1.5 GHz) interface being developed
with Shiron which can support a series of modems for a range of applications,
including rural telephony and digital video. These earth stations may be
operated on either preassigned channels or channels assigned on demand, allowing
efficient transponder utilization. Antenna sizes range from 1.2 to 3.7 meters.
These earth stations are expected to be marketed for less than $20,000.
 
    MOBILE SATELLITE SYSTEM RADIO FREQUENCY TERMINALS.  These terminals are a
component of the mobile satellite system gateways expected to be used to
interface between terrestrial telephone networks and satellites that communicate
with mobile land-, air- and sea-based terminals. The Company has designed one
version of this terminal in concert with Hughes Network Systems and another
version in concert with Thomson. Both versions incorporate innovative
proprietary designs which provide L-band interfaces between an earth station's
radio frequency equipment and baseband equipment. Antenna sizes range from 4.5
to 16 meters. These terminals are expected to be marketed primarily to prime
contractors at prices ranging from approximately $500,000 to $2.0 million.

NETSAT DATA COMMUNICATIONS SERVICES
 
    The Company's NetSat services are designed to provide broadband access to
data communications media such as the Internet, corporate intranet applications
and business data applications by integrating end-user terminals, satellite
communications equipment and international networks. NetSat provides data
communications services through either a one-way satellite downlink using HNS'
DirecPC Terminal linked to existing terrestrial communications infrastructure,
or through a two-way satellite uplink/downlink using a NetSat Direct Terminal,
which consists of an HNS DirecPC Terminal integrated with an HNS Personal Earth
Station. Any use by NetSat of HNS's DirecPC technology will require the grant of
a license from HNS to NetSat. HNS is under no obligation to grant such licenses
and no assurance can be given that NetSat will be able to obtain licenses from
HNS on acceptable terms, or at all. See "Risk Factors-- Reliance on Strategic
Relationships." NetSat currently has entered into a value-added reseller
agreement with HOT for sales of DirecPC and Personal Earth Station 5000 products
in certain Eastern European countries.
 
    In the future, NetSat intends to offer a range of options and accessories to
permit value-added resellers to deliver reliable, cost-effective turnkey
solutions to their customers. These options are expected to include multimedia
PCs, alternative antenna configurations, local area network ("LAN") servers and
custom system configurations. NetSat's Network Operations Center ("NOC"), when
functional, will provide 24-hour technical support, as well as a customer and
billing database and certain other functions such as a domain name service, a
mail server and a Web server. NetSat also expects to offer its customers the
ability to access customized interactive multimedia program content developed
for specific user groups.
 
NETSAT INFRASTRUCTURE
 
    The DirecPC Terminal is a two-way Internet access terminal with a satellite
downlink of 400 Kbps from the Internet, approximately seven times as fast as a
terrestrial ISDN line, and a standard dial-up modem to access and send requests
to the Internet. This Internet connection can be routed through either a local
Internet service provider or one of the proposed regional NetSat satellite
gateways. In locations where terrestrial connections do not exist or are not
economically or practically feasible, the DirecPC Terminal downlink can be
integrated with an HNS Personal Earth Station uplink to form the NetSat Direct
Terminal, a small satellite earth station system that can provide the user with
two-way direct satellite access to the Internet and other data communications
services. With a NetSat Direct Terminal, the customer request channel is
uplinked at 19.2 Kbps and is designed to be connected from the NetSat regional
satellite gateway to NetSat's planned NOC in Hauppauge, New York, and then into
the Internet. Responses from the Internet to either a DirecPC unit or a NetSat
Direct Terminal will pass through NetSat's NOC to the regional gateway, and will
be placed onto the satellite link and transmitted to the terminal units at 400
Kbps.

STRATEGIC RELATIONSHIPS
 
    A key element of the Company's strategy is to establish strategic customer
and supplier relationships. The Company selects its strategic customers and
suppliers based on many factors, including technical capability, geographic
location and market presence. The Company has found that making an equity
investment in a supplier, or allowing a customer to acquire an equity interest
in it, strengthens the relationship and results in greater awareness of the
Company's capabilities by potential customers as well as referrals of potential
projects to the Company by its strategic customers.
 
    The following table sets forth certain information regarding the Company's
strategic relationships:

SALES AND MARKETING
 
    The Company markets its products and services to prime communications
infrastructure contractors, PTTs, other telecommunications carriers, producers
and distributors of news and entertainment content and other corporations
through sales representatives in foreign countries as well as its sales and
marketing offices in Hauppauge, New York, Atlanta, Georgia, and Hong Kong. The
Company presently employs 23 persons with marketing responsibility, of which 10
are engaged in marketing on a full-time basis.
 
    The Company applies a "project team" approach to identifying, obtaining and
maintaining customer accounts by grouping sales representatives, marketing
executives, business execution teams and account managers together to develop
close and continuing relationships with its customers. The Company's sales
representatives in foreign countries provide local presence and identify
prospective customers for the Company's marketing executives. The marketing
executives and associated business execution teams work together to develop
relationships with these customers, and ultimately obtain orders for the
Company's products or services. The business execution teams manage the accounts
on a day-to-day basis and long-term customers are assigned to an account manager
who usually also functions as a project engineer for that account. The Company
believes that this account management focus provides continuity and loyalty
between the Company and its customers and fosters long-term relationships that
lead to follow-up work and referrals to new customers.
 
    In addition to obtaining business through its project team approach, the
Company obtains sales leads for new customers through referrals from existing
customers, industry suppliers, and other sources such as participation in trade
shows. The Company also directs its marketing efforts to its strategic allies,
primarily through the Company's senior management. In some cases a strategic
ally may be the prime contractor for a system or network installation and will
subcontract the ground segment of the project to the Company. In other cases,
the strategic ally may recommend the Company as prime contractor for the design
and supply of a system.
 
    The Company's marketing strategy for NetSat's Internet access and data
communications services is at an early stage of development. The Company
anticipates that such strategy will be carried out primarily through local joint
ventures and value added resellers in each of the countries in which it markets
its services, depending on the capabilities of such partners and resellers, the
nature and location of prospective customers in such countries and the
particular communications infrastructure requirements and regulatory structure
of each potential market. The Company expects that members of senior management
will play a role in developing and maintaining relationships with local value
added resellers, joint venture partners and local partners.

    The Company typically relies upon a small number of customers for a large
portion of its revenues. For example, approximately 43% and 17% of the Company's
revenues in fiscal 1996 and for the six months ended December 31, 1996,
respectively, were derived from sales to Hughes Network Systems. At December 31,
1996, $16.5 million, or approximately 61% of the Company's backlog, was
accounted for by a contract between the Company and A Sky B. The Company expects
that in the near term a significant portion of its revenues will continue to be
derived from one or a limited number of customers (the identity of whom may vary
from year to year) as the Company seeks to expand its business and its customer
base. The reduction, delay, or cancellation of orders from one or more of such
significant customers would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
BACKLOG
 
    At December 31, 1996, the Company's backlog of undelivered orders was $27.1
million (approximately 82% of which is expected to be delivered during fiscal
1997) compared with $8.0 million at December 31, 1995. The Company records an
order in backlog when it receives a firm contract or purchase order which
identifies product quantities, sales price and delivery dates. Backlog
represents the amount of unrecorded revenue on undelivered orders and a
percentage of revenues from sales of products that have
 
                                       42
<PAGE>
been shipped but have not been accepted by the customer. The Company's backlog
at any given time is not necessarily indicative of future period revenues. While
from time to time a substantial portion of the Company's backlog has been
comprised of large orders, the cancellation of any of which could have a
material adverse effect on the Company's operating results, the Company to date
has not experienced significant changes in its backlog from cancellations or
revisions of orders. See "Risk Factors--Customer Concentration."
 
PRODUCT DESIGN, ASSEMBLY AND TESTING
 
    The Company assigns a project team to each contract into which it enters.
The project team is led by a project engineer who is responsible for execution
of the project process, which includes engineering and design, assembly and
testing, installation and customer acceptance. Project teams generally consist
of between two and 10 employees and include engineers, integration specialists,
buyer-planners and an operations team. The Company's proprietary products and
system designs are utilized in the engineering and design phases of a project.
Once a system is designed, the integration specialist works with the buyer-
planner and the operations team to assure a smooth transfer from the engineering
phase to the integration phase. The integration phase consists mainly of
integration of purchased equipment, components and subsystems into a complete
functioning system. Assembly, integration and test operations are conducted on
both an automated and manual basis, depending primarily on production volume.
The Company provides facilities for complete in-plant testing of all its systems
before delivery in order to assure all performance specifications will be met
during installation at the customer's site.
 
    The Company employs formal Total Quality Management programs and other
training programs, and has entered the International Organization of Standards
quality certification process for ISO 9001, a standard sometimes imposed by
foreign buyers, that enumerates certain requirements an organization must follow
in order to assure consistent quality in the supply of products and services.
The certification process qualifies the Company for access to virtually all
international projects, and the Company believes that this represents a
competitive advantage. The Company has designed its processes and procedures
based on ISO 9001 requirements and believes, although there can be no
assurances, that certification will be completed in a timely manner.
 
    The Company currently procures most of the critical components and services
for its products from single or limited sources in connection with specific
contracts and does not otherwise carry significant inventories or have long-term
or exclusive supply contracts with its source vendors. The Company has from time
to time experienced delays in receiving products from certain of its vendors due
to quality control or manufacturing problems, shortages of materials or
components or product design difficulties. There can be no assurance that
similar problems will not recur or that replacement products will be available
when needed at commercially reasonable rates, or at all. If the Company were to
change certain of its vendors, the Company would be required to perform
additional testing procedures upon the components supplied by such new vendors,
which could prevent or delay product shipments. Additionally, prices could
increase significantly in connection with changes of vendors. Any inability of
the Company to obtain timely deliveries of materials of acceptable quality or
timely services, or any significant increase in the prices of materials or
services, could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Risk Factors--Risks of
Fixed-Price Contracts," "--Quarterly Fluctuations" and "--Dependence upon
Suppliers; Sole and Limited Sources of Supply."
 
RESEARCH AND DEVELOPMENT
 
    The Company outsources much of its research and development by making
strategic investments in certain suppliers who perform research and development
for the Company. This provides the Company with a cost-effective way to develop
new technology, while minimizing its direct expenditures. The Company believes
that outsourcing research and development, where the costs are funded partially
by the investments made in its strategic suppliers, allows the Company to retain
its flexibility in developing
 
                                       43
<PAGE>
solutions for its customers, while at the same time leaving open the opportunity
to develop proprietary products through its strategic supplier relationships.
 
    The Company's internal research and development efforts generally focus on
the development of products not available from other suppliers to the industry.
Current efforts are focused on developing a compact digital earth station and
other customizable systems. Through December 31, 1996, the Company has incurred
$941,000 in internal research and development expenses.
 
COMPETITION
 
    The markets for both ground segment systems and networks and
satellite-delivered data communications services are highly competitive. Many of
the Company's competitors have greater market presence, engineering and
marketing capabilities, and financial, technological and personnel resources
than those available to the Company. As a result, such competitors may be able
to develop and expand their products and services more quickly, adapt more
swiftly to new or emerging technologies and changes in customer requirements,
take advantage of acquisition and other opportunities more readily, and devote
greater resources to the marketing and sale of their products and services than
can the Company. In addition, there are limited barriers to entry in the
Company's markets and certain of the Company's strategic suppliers and customers
have technologies and capabilities in the Company's product areas and could
choose to compete with the Company or to replace the Company's products or
services with their own. The entry of new competitors, the decision by a
strategic ally to compete with the Company or the decision by a customer to
develop and employ in-house capability to satisfy its satellite communications
needs could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    The Company believes that its ability to compete successfully in the
satellite ground segment market is based primarily on its ability to provide a
solution which fits the customer's requirements, as well as on price,
performance, reputation of its management, on-time delivery, reliability and
customer support. The Company believes its success in the satellite-delivered
data communications services market will depend primarily on its ability to
provide prompt delivery and installation, competitive pricing, consistent and
reliable connections, and customer support.
 
    The Company's primary competitors in the satellite ground segment market
generally fall into the following groups: (i) vertically integrated satellite
systems providers such as Nippon Electric Corporation ("NEC"), California
Microwave, Inc. ("CMI"), Scientific-Atlanta, Inc. and ComSat RSI and (ii) system
integrators such as Engineering & Technical Services and IDB Systems, a division
of LDDS Worldcom Inc. In the satellite-delivered data communications (including
Internet) services market, while the Company expects to cooperate with many
local providers, the Company may compete with other satellite communication
companies as they develop technology in this area as well as conventional
Internet services providers, such as Uunet Technology, Inc., NETCOM On-Line
Communication Services, Inc. and PSINet Inc. In addition, the Company may
compete with local governmental PTTs and other local access providers which
often have monopoly rights for certain services including telephony.
 
    The Company anticipates that its competitors may develop or acquire products
that provide functionality that is similar to that provided by the Company's
products and that such products may be offered at a significantly lower price or
bundled with other products. In addition, current and potential competitors in
both markets have established or may establish cooperative relationships among
themselves or with third parties to increase the ability of their products and
services to address the needs of the Company's current and prospective
customers. Accordingly, it is possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share, any of which would have a material adverse effect on the
Company's business, results of operations and financial condition. There can be
no assurance that the Company will be able to compete successfully against
current or future competitors or that
 
                                       44
<PAGE>
competitive pressures will not have a material adverse effect on the Company's
business, results of operations and financial condition.
 
INTELLECTUAL PROPERTY
 
    The Company relies heavily on the technological and creative skills of its
personnel, new product developments, computer programs and designs, frequent
product enhancements, reliable product support and proprietary technological
expertise in maintaining its competitive position, and lacks patent protection
for its products and services. There can be no assurance that others will not
independently develop or acquire substantially equivalent techniques or
otherwise gain access to the Company's proprietary and confidential
technological expertise or disclose such technologies or that the Company can
ultimately protect its rights to such proprietary technological expertise.
 
    The Company generally relies on confidentiality agreements with its
consultants, key employees and sales representatives to protect its proprietary
technological expertise, and generally controls access to and distribution of
its technology, software and other proprietary information. Despite these
precautions, there can be no assurance that such agreements will not be
breached, that the Company will have adequate remedies for any such breach or
that a third party will not copy or otherwise obtain and use the Company's
products or technology without authorization or develop similar products or
technology independently. Failure by the Company to maintain protection of its
proprietary technological expertise for any reason could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Risk Factors--Proprietary Technology; Risk of Infringement."
 
    The Company is subject to the risk of alleged infringement of intellectual
property rights of others. Most of the Company's officers and employees were
formerly officers or employees of other companies in the industry. The Company
believes that neither it nor its officers or employees have violated any
agreements with, or obligations to, prior employers. Although the Company is not
aware of any pending or threatened infringement claims with respect to the
Company's current or future products, there can be no assurance that third
parties, including previous employers, will not assert such claims or that any
such claims will not require the Company to enter into license arrangements or
result in protracted and costly litigation, regardless of the merits of such
claims. No assurance can be given that any necessary licenses will be available
or that, if available, such licenses can be obtained on commercially reasonable
terms. Furthermore, litigation may be necessary to enforce or protect the
Company's intellectual property rights, to determine the validity and scope of
the proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    The Company currently has two patent applications pending in the United
States and intends to seek further patents on its technology, if appropriate.
There can be no assurance that patents will issue from any of the Company's
pending or any future applications or that any claims allowed from such
applications will be of sufficient scope or strength, or be issued in all
countries where the Company's products can be sold, to provide meaningful
protection or any commercial advantage to the Company. Also, competitors of the
Company may be able to design around the Company's patents. The laws of certain
foreign countries in which the Company's products are or may be developed,
manufactured or sold may not protect the Company's products or intellectual
property rights to the same extent as do the laws of the United States and thus
make the possibility of piracy of the Company's technology and products more
likely.
 
    The Company has filed an application for registration of Globecomm Systems
Inc. as a service mark in the United States and has filed applications for
registration of NetSat Express as a trademark and service mark in the United
States and in Singapore, the European Union and the Russian Federation and as a
trademark in Brazil, and intends to seek registration of other trademarks and
service marks in the future. There can be no assurance that registrations will
be granted from any of the Company's pending or
 
                                       45
<PAGE>
future applications, or that any registrations that are granted to the Company
will prevent others from using similar trademarks and service marks in
connection with related goods and services.
 
GOVERNMENT REGULATION
 
    The Company is subject to various federal laws and regulations which may
have negative effects on the Company. The operation of the teleport (a group of
transmit earth stations) that the Company intends to construct in Hauppauge, New
York, will be subject to regulation by the FCC for domestic and international
carriage and by government agencies in other countries. The Company's
transmission of voice and data for its data communications business through the
teleport must be licensed by the FCC for domestic and international service.
Additionally, a Certificate of Public Convenience and Necessity ("CPCN") must be
obtained and a tariff filed for the provision of international service.
 
    To receive the license for domestic service, the Company must submit an
application which contains technical information about the proposed teleport and
a demonstration of the public interest aspects of the teleport, including a
shareholder list and a statement that the Company's ownership complies with the
FCC's foreign ownership restrictions for licensees. Under the FCC Rules and
Regulations, non-U.S. citizens or their representatives, foreign governments, or
corporations otherwise subject to control by non-U.S. citizens, may not own more
than 20% of a licensee directly, or, if the FCC finds it consistent with the
public interest, may not own more than 25% of the parent of a licensee. Non-U.S.
citizens may not serve as officers of a licensee or as members of a licensee's
board of directors, although the FCC may waive this requirement in whole or in
part. Failure to comply with these requirements may result in the FCC issuing an
order to the entity requiring divestiture of alien ownership to bring the entity
into compliance with the FCC Rules and Regulations. In addition, fines, a denial
of renewal or revocation of the license are possible. The Company has no
knowledge of any present foreign ownership which would result in a violation of
the FCC Rules and Regulations, but there can be no assurance that foreign
holders will not in the future hold more than 20% or 25% of the Common Stock of
the Company.
 
    The application, if accepted for filing, is placed on public notice for 30
days. After the notice period, the FCC determines whether the application should
be granted. If the license is granted, the teleport must be constructed and made
operational within twelve months from the date of the license grant. The Company
will have to file annual reports with the FCC indicating modifications, project
status and changes in foreign ownership. The Company is in the process of
preparing the application and there can be no assurance that the FCC will grant
a license for the teleport.
 
    With respect to international service, the Company must submit an
application to the FCC for a CPCN which is placed on public notice and, if no
comments are received, automatically granted on the 36th day following
publication. The Company will also be required to file and maintain tariffs
containing the specific rates, terms and conditions applicable to its services.
The tariffs can become effective one day after public notice of grant of the
CPCN. No assurance can be given that the Company will receive a CPCN or
successfully file and maintain its tariff.
 
    Regulatory schemes in countries in which the Company may seek to provide its
satellite-delivered data communications services may impose impediments on the
Company's operations. Certain countries in which the Company intends to operate
have telecommunications laws and regulations that do not currently contemplate
technical advances in broadcast technology such as Internet/intranet
transmission by satellite. There can be no assurance that the present regulatory
environment in any such country will not be changed in a manner which may have a
material adverse impact on the Company's business. The Company or its local
partners typically must obtain authorization for each country in which the
Company provides its satellite-delivered data communications services. Although
the Company believes that it or its local partners will be able to obtain the
requisite licenses and approvals from the countries in which the Company intends
to provide service, the regulatory schemes in each country are different and
thus there may be instances of noncompliance of which the Company is not aware.
Although the Company believes
 
                                       46
<PAGE>
these regulatory schemes will not prevent the Company from pursuing its business
plan, there can be no assurance such licenses and approvals are or will remain
sufficient in the view of foreign regulatory authorities, or that necessary
licenses and approvals will be granted on a timely basis in all jurisdictions in
which the Company wishes to offer its services or that restrictions applicable
thereto will not be unduly burdensome.
 
    The Company's Internet operations (other than the operation of a teleport)
are not currently subject to direct government regulation in most countries, and
there are currently few laws or regulations directly applicable to access to or
commerce on the Internet. However, due to the increasing popularity and use of
the Internet, it is likely that a number of laws and regulations may be adopted
at the local, national or international levels with respect to the Internet,
covering issues such as user privacy and expression, pricing of products and
services, taxation, advertising, intellectual property rights, information
security or the convergence of traditional communication services with Internet
communications. For example, the Telecommunications Act of 1996 (the
constitutionality of certain portions of which is currently under challenge) was
recently enacted in the United States, and imposes criminal penalties via the
Communications Decency Act (or "CDA") on anyone who distributes obscene,
lascivious or indecent communications over the Internet. It is anticipated that
a substantial portion of the Company's Internet operations will be carried out
in countries which may impose greater regulation of the content of information
coming into the country than that which is generally applicable in the United
States. To the extent that the Company provides content as a part of its
Internet services, it will be subject to any such laws regulating content.
Moreover, the adoption of any such laws or regulations may decrease the growth
of the Internet, which could in turn decrease the demand for the Company's
Internet services or increase the Company's cost of doing business or in some
other manner have a material adverse effect on the Company's business, operating
results and financial condition. In addition, the applicability to the Internet
of existing laws governing issues such as property ownership, copyrights and
other intellectual property issues, taxation, libel and personal privacy is
uncertain. The vast majority of such laws were adopted prior to the advent of
the Internet and related technologies and, as a result, do not contemplate or
address the unique issues of the Internet and related technologies. Changes to
such laws intended to address these issues, including some recently proposed
changes, could create uncertainty in the marketplace which could reduce demand
for the Company's services, could increase the Company's cost of doing business
as a result of costs of litigation or increased product development costs, or
could in some other manner have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The sale of the Company's ground segment systems and networks outside the
United States is subject to compliance with the regulations of the United States
Export Administration Regulations. The absence of comparable restrictions on
competitors in other countries may adversely affect the Company's competitive
position. In addition, in order to ship its products into European Union
countries, the Company must satisfy certain technical requirements. If the
Company were unable to comply with such requirements with respect to a
significant quantity of the Company's products, the Company's sales in Europe
could be restricted, which could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
EMPLOYEES
 
    As of December 31, 1996, the Company had 60 full-time employees, including
27 in engineering and program management, 12 in the manufacturing and
manufacturing support group, 10 in sales and marketing, and 11 in management and
administration. The Company's employees are not covered by any
collective-bargaining agreements. The Company believes that its relations with
its employees are good.
 
FACILITIES
 
    The Company's principal offices and production facilities are currently
located in approximately 20,000 square feet of space in an industrial facility
located at 375 Oser Avenue, Hauppauge, New York.
 
                                       47
<PAGE>
The Company leases the space under an agreement which terminates on November 30,
1998 with a base rent of $105,000 per year. In December 1996, the Company
purchased 121,830 square feet of space in a facility in Hauppauge on 7.2 acres
where the Company intends to move its principal offices and production
facilities by May 1997. The Company has a one-year lease on office space in Hong
Kong at a monthly rental fee (including maintenance fees) of approximately
$3,000. The Company also leases office space in the Atlanta, Georgia, area under
a three-year lease at an initial base monthly rent of $1,750, which rental
amount increases in years two and three of the lease and is currently $1,820 per
month. NetSat's principal offices are located in approximately 3,000 square feet
of space located at 400 Oser Avenue, Hauppauge, New York, which NetSat leases on
a month-to-month basis, at a monthly rent of $2,500.
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any material legal proceedings.

    DAVID E. HERSHBERG founded the Company in 1994 and has served as Chief
Executive Officer and Chairman of the Board of Directors since its inception.
From 1976 to 1994, Mr. Hershberg was the President of Satellite Transmission
Systems, Inc. ("STS"), a provider of satellite ground segment systems and
networks, which he founded and which became a subsidiary of CMI. From 1990 to
1994, Mr. Hershberg also served as Group President of the Satellite
Communications Group of CMI, where he also had responsibility for EFData, Inc.,
a manufacturer of satellite communications modems and for Viasat Technology
Corp. ("Viasat"), a manufacturer of communications systems which specialized in
portable and mobile satellite communications equipment. Mr. Hershberg headed the
Space Communications division of ITT Corporation from 1968 to 1972, and the
Systems Division of Comtech Systems, Inc. ("Comtech") from 1972 to 1976. Mr.
Hershberg is a Director of Primus Telecommunications Group, Incorporated
("Primus"), a telecommunications company providing long distance services. He
holds a B.S.E.E. from Rensselaer Polytechnic Institute, an M.S.E.E. from
Columbia University and an M.S. in Management Science from Stevens Institute of
Technology.
 
    KENNETH A. MILLER has served as President and a Director since joining the
Company in November 1994. From 1978 to 1994, he held various positions with STS,
and succeeded Mr. Hershberg as President of that company in 1994. During his

1997 STOCK INCENTIVE PLAN
 
    The Company's 1997 Stock Incentive Plan (the "1997 Plan") is intended to
serve as the successor equity incentive program to the Company's Incentive Stock
Option Plan and Director Stock Option Plan (the "Predecessor Plans"). The 1997
Plan was adopted by the Board of Directors on February 26, 1997, subject to
stockholder approval. 2,280,000 shares of Common Stock have been initially
authorized for issuance under the 1997 Plan. This share reserve is comprised of
(i) the shares which remained available for issuance under the Predecessor
Plans, including the shares subject to outstanding options thereunder, plus (ii)
an additional increase of 285,000 shares. This initial share reserve will
increase on the first trading day of each calendar year beginning with the 1998
calendar year by one percent (1%) of the aggregate shares of Common Stock
outstanding on the last business day of the preceding calendar year. However, in
no event may any one participant in the 1997 Plan receive option grants or
direct stock issuances for more than 1,425,000 shares in the aggregate per
calendar year.
 
    Outstanding options under the Predecessor Plans will be incorporated into
the 1997 Plan upon the date of this Offering, and no further option grants will
be made under the Predecessor Plans. The incorporated options will continue to
be governed by their existing terms, unless the Plan Administrator elects to
extend one or more features of the 1997 Plan to those options. However, except
as otherwise noted below, the outstanding options under the Predecessor Plans
contain substantially the same terms and conditions summarized below for the
Discretionary Option Grant Program in effect under the 1997 Plan.
 
    The 1997 Plan is divided into five separate components: (i) the
Discretionary Option Grant Program, (ii) the Salary Investment Option Grant
Program, (iii) the Stock Issuance Program, (iv) the Automatic Option Grant
Program and (v) the Director Fee Option Grant Program.
 
                                       54
<PAGE>
    The Discretionary Option Grant, Salary Investment Option Grant and Stock
Issuance Programs will be administered by the Compensation Committee. The
Compensation Committee as Plan Administrator will have complete discretion to
determine which eligible individuals are to receive option grants or stock
issuances, the time or times when such option grants or stock issuances are to
be made, the number of shares subject to each such grant or issuance, the status
of any granted option as either an incentive stock option or a non-statutory
stock option under the Federal tax laws, the vesting schedule to be in effect
for the option grant or stock issuance and the maximum term for which any
granted option is to remain outstanding.
 
    Under the Discretionary Option Grant Program, eligible individuals may, at
the discretion of the Plan Administrator, be granted options to purchase shares
of Common Stock at an exercise price not less than 85% of their fair market
value on the grant date.
 
    Stock appreciation rights are authorized for issuance under the
Discretionary Option Grant Program which provide the holders with the election
to surrender their outstanding options for an appreciation distribution from the
Company equal to the excess of (i) the fair market value of the vested shares of
Common Stock subject to the surrendered option over (ii) the aggregate exercise
price payable for such shares. Such appreciation distribution may be made in
cash or in shares of Common Stock.
 
    The Plan Administrator has the authority to effect the cancellation of
outstanding options under the Discretionary Option Grant Program (including
options incorporated from the Predecessor Plans) in return for the grant of new
options for the same or different number of option shares with an exercise price
per share based upon the fair market value of the Common Stock on the new grant
date.
 
    Under the Stock Issuance Program, eligible individuals may, in the Plan
Administrator's discretion, be issued shares of Common Stock directly, through
the purchase of such shares at a price not less than 85% of their fair market
value at the time of issuance or as a bonus tied to the performance of services.
 
    In the event that there is a change in control of the Company (including the
acquisition of more than 35% of the outstanding voting stock), each outstanding
option under the Discretionary Option Grant Program will automatically
accelerate in full, and all unvested shares under the Stock Issuance Program
will immediately vest. Options currently outstanding under the Incentive Stock
Option Plan will accelerate upon an acquisition of the Company by merger or
asset sale, but such options are not subject to acceleration upon a hostile
change in control of the Company. Options currently outstanding under the
Director Stock Option Plan accelerate upon the optionee's retirement, disability
or death, or if the Company executes an agreement pursuant to which the Company
is acquired by merger or asset sale or an acquisition (or increase in ownership)
by any person to more than 20% of the outstanding voting stock.
 
    Under the Salary Investment Option Grant Program, selected executive
officers and other highly compensated employees may elect to have a portion of
their base salary invested each year in special option grants. The Plan
Administrator will have the discretion to determine the calendar years for which
the program is to be in effect and to select the individuals eligible to
participate in the program. For each year the Plan Administrator elects to
activate the Salary Investment Option Grant Program, each individual selected
for participation may elect, prior to the start of the calendar year, to reduce
his base salary for that calendar year by a specified dollar amount not less
than $5,000 nor more than $50,000. In return, the officer will automatically be
granted, on or before the last trading day in January of the calendar year for
which the salary reduction is to be in effect, a non-statutory option to
purchase that number of shares of Common Stock determined by dividing the salary
reduction amount by two-thirds of the fair market value per share of Common
Stock on the grant date. The option will be exercisable at a price per share
equal to one-third of the fair market value of the option shares on the grant
date. As a result, the built-in gain on the option at the time of grant will be
equal to the salary reduction amount. The option will vest in a series of 12
equal monthly installments over the calendar year for which the salary reduction
is in effect and will be subject to full and immediate vesting upon certain
changes in the ownership or control of the Company.
 
                                       55

    Under the Automatic Option Grant Program, each individual who first becomes
a nonemployee Board member on or after the date the Underwriting Agreement for
this Offering is executed will receive an option grant on such date for 15,000
shares of Common Stock, provided such individual has not otherwise been in the
prior employ of the Company and provided he is not serving as a member of the
Board pursuant to contractual rights granted to certain groups of stockholders
in connection with their purchase of stock in the Company.
 
    Each automatic grant will have a term of 10 years, subject to earlier
termination following the optionee's cessation of Board service. Each automatic
option will be immediately exercisable; however, any shares purchased upon
exercise of the option will be subject to repurchase should the optionee's
service as a nonemployee Board member cease prior to vesting in the shares. Each
15,000-share grant will vest to the extent of one-third of the number of shares
granted (5,000 shares), on the first anniversary of the date of grant, and
cumulatively to the extent of an additional one-third, on each of the next two
succeeding anniversaries of the date of grant. However, each outstanding option
will immediately vest upon: (i) certain changes in the ownership or control of
the Company or (ii) the death or disability of the optionee while serving as a
Board member.
 
    Under the Director Fee Option Grant Program, nonemployee Board members may
elect to have all or any portion of any annual retainer fee otherwise payable in
cash applied to a special option grant. Each member who elects, prior to the
start of a calendar year, to apply all or any portion of his retainer fee for
that calendar year to the acquisition of an option will automatically be
granted, on the first trading day in the calendar year for which the salary
reduction is to be in effect, a non-statutory option to purchase that number of
shares of Common Stock determined by dividing the amount of the retainer fee
subject to the election by two-thirds of the fair market value per share of
Common Stock on the grant date. The option will be exercisable at a price per
share equal to one-third of the fair market value of the option shares on the
grant date. As a result, the built-in gain on the option at the time of grant
will be equal to the amount of the retainer fee subject to the election. The
option becomes exercisable for 50% of the option shares upon completion of six
(6) months of Board service in the calendar year for which the election is in
effect and the balance of the shares will become exercisable in a series of six
(6) equal monthly installments upon completion of each additional month of Board
service during that calendar year. The option will be subject to full and
immediate vesting upon certain changes in the ownership or control of the
Company.
 
    The Board may amend or modify the 1997 Plan at any time. The 1997 Plan will
terminate on February 25, 2007, unless sooner terminated by the Board.
 
EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS
 
    The Company has entered into three-year employment agreements with each of
Messrs. Hershberg and Miller as of January 27, 1997 (the "Executive
Agreements"). Messrs. Hershberg and Miller are required to devote their
full-time efforts to the Company as Chairman of the Board and Chief Executive
Officer, and as President, respectively. The Company is required to compensate
Messrs. Hershberg and Miller at annual rates of $165,000 and $160,000,
respectively (which amounts are reviewed annually by the Board of Directors and
are subject to increase at their discretion). Messrs. Hershberg and Miller are
entitled to all employee benefits generally made available to executive
officers. If the Company terminates the Executive Agreements other than for
disability or cause, the Company will have the following obligations: (i) if the
termination is after the end of the initial three-year term, the Company must
pay the terminated executive one-twelfth of his then applicable base salary as
severance pay and (ii) if the termination is before the end of the initial
three-year term, the Company must pay to the terminated executive, as they
become due, all amounts otherwise payable if he had remained employed by the
Company until the end of the third year of the Executive Agreements. If their
employment is terminated other than for cause following a change of control of
the Company, each of Messrs. Hershberg and Miller will be entitled to receive:
(i) a cash payment equal to three times his respective annual base salary plus
fringe benefits and bonus, (ii) a cash payment equal to three times the
Company's 401(k) contribution for
 
                                       56
<PAGE>
such executive and (iii) medical benefits for one year for the executive and his
dependents. In addition, all stock options will become immediately exercisable
upon a change of control. The definition of "change in control" in the Executive
Agreements is the same as in the 1997 Plan.
 
    The Compensation Committee as Plan Administrator of the 1997 Plan will have
the authority to provide for the accelerated vesting of the shares of Common
Stock subject to outstanding options held by any executive officer or the shares
of Common Stock subject to direct issuances held by any such individual, in
connection with certain changes in control of the Company or the subsequent
termination of the executive officer's employment following the change in
control.
 
401(K) PLAN
 
    The Company participates in a tax-qualified employee savings and retirement
plan (the "401(k) Plan") which covers all of the Company's employees with one
(1) month of service before the end of the preceding quarter who are at least 21
years of age. Pursuant to the 401(k) Plan, employees may elect to reduce their
current compensation by up to 20% and have the amount of such reduction
contributed to the 401(k) Plan. The Company matches 100% of the first 4% of such
contributions. In addition, the 401(k) Plan provides for discretionary
profit-sharing contributions in an amount determined each year by the Board of
Directors. The Company has not made any such discretionary profit-sharing
contributions under the Plan to date. The 401(k) Plan further provides for
additional voluntary contributions (which are made on an after-tax basis) by
Plan participants. The 401(k) Plan is intended to qualify under Section 401 of
the Internal Revenue Code of 1996, as amended, so that salary reduction
contributions by employees, matching or profit-sharing contributions by the
Company, and income earned on plan contributions, are not taxable to employees
until withdrawn from the 401(k) Plan, and so that contributions by the Company
will be deductible by the Company when made. The Trustees under the 401(k) Plan,
at the direction of each participant, invest the assets of the 401(k) Plan in
one or more of several investment options.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    As of the date of this Prospectus, the Company's Compensation Committee
consists of Mr. Fialkov and Dr. Waylan. Prior to this time, effective September
19, 1996, the Board elected a Compensation Committee consisting of Messrs.
Hershberg and Fialkov and Dr. Harrison. From February 21, 1995 to September 18,
1996, the Compensation Committee consisted of Mr. Fialkov and Mr. Andrew B.
Krieger (who is no longer a Director of the Company). Prior to that time,
decisions concerning the compensation of executive officers were made by the
entire Board of Directors. Certain members of the Company's Board of Directors
are parties to transactions with the Company. See "Certain Transactions."
 
KEY-PERSON LIFE INSURANCE
 
    The Company maintains key-person life insurance policies on the life of Mr.
Hershberg in the amount of $1.0 million and on the lives of Messrs. Miller,
DiCicco, Woodring, Yablonski and Melfi in the amount of $500,000 for each.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's Certificate of Incorporation provides that, except to the
extent prohibited by the Delaware General Corporation Law (the "Delaware Law"),
its directors shall not be personally liable to the Company or its stockholders
for monetary damages for any breach of fiduciary duty as directors of the
Company. Under Delaware law, the directors have a fiduciary duty to the Company
which is not eliminated by this provision of the Certificate of Incorporation
and, in appropriate circumstances, equitable remedies such as injunctive or
other forms of nonmonetary relief will remain available. In addition, each
director will continue to be subject to liability under Delaware law for breach
of the director's duty of loyalty to the Company, for acts or omissions which
are found by a court of competent
 
                                       57
<PAGE>
jurisdiction to be not in good faith or involving intentional misconduct, for
knowing violations of law, for actions leading to improper personal benefit to
the director, and for payment of dividends or approval of stock repurchases or
redemptions that are prohibited by Delaware law. This provision also does not
affect the directors' responsibilities under any other laws, such as the Federal
securities laws or state or Federal environmental laws. The Company has obtained
liability insurance for its officers and directors.
 
    Section 145 of the Delaware Law empowers a corporation to indemnify its
directors and officers and to purchase insurance with respect to liability
arising out of their capacity or status as directors and officers, provided that
this provision shall not eliminate or limit the liability of a director: (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the Delaware Law or (iv) for any transaction from which the
director derived an improper personal benefit. The Delaware Law provides further
that the indemnification permitted thereunder shall not be deemed exclusive of
any other rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, vote of stockholders or otherwise. The
Company's Certificate of Incorporation eliminates the personal liability of
directors to the fullest extent permitted by Section 102(b)(7) of the Delaware
Law and provides that to the fullest extent permitted by law, the Corporation
shall fully indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the fact
that such person is or was a director or officer of the Corporation, or is or
was serving at the request of the Corporation as a director or officer of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding.
 
    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate of Incorporation. The Company is not
aware of any threatened litigation or proceeding that may result in a claim for
such indemnification.

broker-dealer in the private placements through an affiliation with NSI. In

Mr. Krieger is the President and Chief Executive Officer, cash commissions

Company has agreed to pay Krieger Associates further cash commissions totaling
an aggregate of $432,000, to be paid in monthly installments over a 36-month
period, of which the Company has paid $12,000 to date. The Company also has

performance of such services since February 1995. In addition, in connection
with these private placements, the Company issued an aggregate of 156,488 shares

shares of Common Stock issued upon conversion of the Class A and Class B

    In November 1995, Thomson purchased 199,500 shares of the Company's Common

                                       59

Board of Directors out of funds legally available therefor. In the event of a
liquidation, dissolution or winding up of the Company, holders of Common Stock
would be entitled to share in the Company's assets remaining after the payment
of liabilities and the satisfaction of any liquidation preference granted to the
holders of any outstanding shares of Preferred Stock. A stockholder, holding in
the aggregate 282,401 shares of Common Stock, has the right to participate in
any private offering of the Company to the extent required to maintain its
percentage ownership in the Company. No other holders of Common Stock have any
preemptive or other subscription rights. The shares of Common Stock are not
convertible into any other security. The outstanding shares of Common Stock are,
and the shares being offered hereby will be, upon issuance and sale, fully paid
and nonassessable.
 
    At January 31, 1997, there were 5,750,191 shares of Common Stock outstanding
(after giving effect to the Preferred Stock Conversion and the Stock Split) and
held of record by 295 stockholders, and options to purchase an aggregate of
1,557,027 shares of Common Stock were also outstanding. See "Management-- 1997
Stock Incentive Plan."
 
PREFERRED STOCK
 
    Upon the consummation of this Offering, the Company will be authorized to
issue 1,000,000 shares of Preferred Stock with such voting rights, designations,
preferences and rights and such qualifications, limitations or restrictions
thereof, as may be determined by the Board of Directors providing for such
series. Although the Company has no current plans to issue any shares of
Preferred Stock, the issuance of Preferred Stock or of rights to purchase
Preferred Stock could be used to discourage an unsolicited acquisition proposal.
In addition, the possible issuance of Preferred Stock could discourage a proxy
contest, make more difficult the acquisition of a substantial block of the
Company's Common Stock or limit the price that investors might be willing to pay
in the future for shares of the Company's Common Stock.
 
    The Company believes that the Preferred Stock will provide the Company with
increased flexibility in structuring possible future financing and acquisitions,
and in meeting other corporate needs that might arise. Having such authorized
shares available for issuance will allow the Company to issue shares of
Preferred Stock without the expense and delay of a special stockholders'
meeting. The authorized shares of Preferred Stock, as well as shares of Common
Stock, will be available for issuance without further action by stockholders,
unless such action is required by applicable law or the rules of any stock
exchange on which the Company's securities may be listed.

COMMON STOCK WARRANTS
 
    As of January 31, 1997, warrants to purchase an aggregate of 64,125 shares
of the Company's Common Stock, all of which will expire on November 21, 2006 and
have an exercise price of $8.07 per share, were outstanding.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
    After this Offering, the holders of       shares of Common Stock (the
"Registrable Securities") will be entitled to certain demand rights with respect
to the registration of the Registrable Securities under the Securities Act.
Under the terms of the agreement between the Company and the holders of the
Registrable Securities, subject to certain restrictions, at any time twelve (12)
months after this Offering is complete, holders holding more than 25% of the
Registrable Securities are entitled to demand that the Company register not less
than 25% of the Registrable Securities under the Securities Act in an
underwritten public offering, the expected aggregate price to the public of
which exceeds $3,000,000 (net of underwriting discounts and commissions).
Additionally, the Company shall not, subject to certain provisions, be obligated
to effect a registration pursuant to such a demand right during the period
starting with the date sixty (60) days prior to the Company's estimated date of
filing of, and ending on a date four (4) months following the effective date of,
a registration statement pertaining to an underwritten public offering of
securities for the account of the Company. The Company is not required to effect
more than one such registration pursuant to such demand registration rights.
 
    Additionally, after this Offering, the holders of       shares of Common
Stock (the "Additional Registrable Securities"), pursuant to the terms of the
July 1995 private placement, will be permitted by the Company to undertake one
demand registration right. Thereafter, the holders of the Additional Registrable
Securities will have piggyback registration rights. Such demand and piggyback
rights are subject to certain restrictions.
 
    Under an additional agreement with respect to the holders of 491,066 shares
of Common Stock (the "Class A Registrable Securities"), the holders of the Class
A Registrable Securities will be entitled to certain demand rights with respect
to the registration of the Class A Registrable Securities under the Securities
Act. Under the terms of the agreement between the Company and the holders of the
Class A Registrable Securities, subject to certain restrictions, at any time
after this Offering is complete, holders holding more than 25% of the Class A
Registrable Securities are entitled to demand that the Company register not less
than 25% of the Class A Registrable Securities under the Securities Act in an
underwritten public offering, the expected aggregate price to the public of
which exceeds $3,000,000 (net of underwriting discounts and commissions). The
Company is not required to effect more than one such registration pursuant to
such demand registration rights.
 
    In addition, under an additional agreement with respect to the holders of
1,383,088 shares of Common Stock (the "Class B Registrable Securities"), after
this Offering, if the Company proposes to register any of its securities under
the Securities Act, either for its own account or for the account of other
security holders exercising registration rights, subject to certain
restrictions, the holders of the Registrable Securities, the Class A Registrable
Securities and the Class B Registrable Securities are entitled to notice of such
registration and are entitled to request inclusion of their Registrable
Securities, Class A Registrable Securities and Class B Registrable Securities
therein. The Company is required to include any Registrable Securities and Class
A Registrable Securities in an unlimited number of such registrations, and any
Class B Registrable Securities in not more than two such registrations. In
addition, at any time fifty-four (54) weeks after the Offering is complete, the
holders of the Class B Registrable Securities, subject to certain restrictions,
are entitled to demand that the Company register the Class B Registrable
Securities under the Securities Act in an underwritten public offering. The
Company is generally required to bear the expenses of any registrations pursuant
to the exercise of the registration rights described herein.
 
                                       64
<PAGE>
    Registration of the Registrable Securities, the Additional Registrable
Securities, the Class A Registrable Securities or Class B Registrable Securities
pursuant to such rights would result in such shares becoming freely tradable
without restriction under the Securities Act immediately upon the effectiveness
of such registration.
 
DELAWARE ANTI-TAKEOVER STATUTE
 
    The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203") which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the date that such stockholder
became an interested stockholder, unless: (i) prior to such date, the Board of
Directors of the corporation approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder, (ii) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced, excluding for purposes of determining the number of
shares outstanding those shares owned (a) by persons who are directors and also
officers and (b) by employee stock plans in which employee participants do not
have the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer or (iii) on or subsequent to
such date, the business combination is approved by the Board of Directors and

consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock which is not owned by the interested stockholder.

    Upon the closing of this Offering, the Company will have       shares of
Common Stock outstanding, assuming no exercise of the over-allotment option or
of warrants and options to acquire an aggregate of       shares outstanding at
December 31, 1996. Of these shares, the       shares registered in this Offering
will be freely tradable without restriction under the Securities Act, unless
they are purchased by "affiliates" of the Company, as that term is used under
the Securities Act. The remaining 5,750,191 shares will be "restricted
securities," as defined in Rule 144 under the Securities Act (the "Restricted
Shares").
 
    As of the date of this Prospectus,       Restricted Shares not subject to
lock-up agreements and not being sold in this Offering will be eligible for sale
in the public market without restriction in reliance on Rule 144(k) under the
Securities Act. All officers and directors of the Company and certain other
stockholders, holding an aggregate of       shares of Common Stock, have agreed
with PaineWebber Incorporated not to offer to sell, sell, contract to sell,
grant any option to sell or otherwise dispose of any shares owned by them for a
period ending 180 days after the date of this Prospectus (the "lock-up period")
without the prior written consent of PaineWebber Incorporated. Certain other
stockholders, holding an aggregate of       shares of Common Stock, have agreed
with PaineWebber Incorporated not to offer to sell, sell, contract to sell,
grant any option to sell or otherwise dispose of any shares owned by them for a
period ending one year after the date of this Prospectus (the "one-year lock-up
period") without the prior written consent of PaineWebber Incorporated. Upon the
expiration of the lock-up period, or earlier upon the consent of PaineWebber
Incorporated       shares will become eligible for sale without restriction
under Rule 144(k), and an additional       shares issuable upon exercise of then
exercisable options will become eligible subject to the restrictions of Rule 144
and, in some cases, Rule 701. Upon the expiration of the one-year lock-up
period, or earlier upon the consent of PaineWebber Incorporated       shares

additional       shares issuable upon exercise of then exercisable options will
become eligible subject to the restrictions of Rule 144 and, in some cases, Rule
701.
 
    In general, under Rule 144, as it will be in effect as of April  , 1997, any
person (or persons whose shares are aggregated) who has beneficially owned his
or her restricted securities (as that term is defined in Rule 144) for at least
one year is entitled to sell, within any three-month period, a number of such
securities that does not exceed the greater of 1% of the then outstanding shares
of the Company's Common Stock (approximately       shares immediately after this
Offering) or the average weekly trading volume during the four calendar weeks
preceding the date on which notice of such sale was filed under Rule 144,
provided certain requirements concerning availability of public information,
manner of sale and notice of sale are satisfied. A person who is not an
affiliate, has not been an affiliate within three months prior to the sale and
has beneficially owned the restricted securities for at least two years is
entitled to sell such shares under Rule 144(k) without regard to any of the
limitations described above. In meeting the one- and two-year holding periods
described above, a holder of Restricted Shares may include under certain
circumstances the holding period of a prior owner. Currently, the holding
periods are two years and three years, respectively.
 
    Any employee or director of or consultant to the Company who has been
granted options to purchase shares or who has purchased shares pursuant to a
written compensatory plan or written contract prior to the effective date of
this Offering pursuant to Rule 701 will be entitled to rely on the resale
provisions of Rule 701, which permits nonaffiliates to sell their Rule 701
shares without having to comply with the public information, holding-period,
volume-limitation or notice provisions of Rule 144 and permits affiliates to
sell their Rule 701 shares without having to comply with the Rule 144 holding
period restrictions, in each case commencing 90 days after the date of this
Prospectus.
 
    The Company intends to file, on or about the date of the Prospectus, a
registration statement on Form S-8 under the Securities Act to register shares
of Common Stock reserved for issuance under the Predecessor Plans and the 1997
Plan, including, in some cases, shares for which an exemption under
 
                                       66
<PAGE>
Rule 144 or Rule 701 would also be available, thus permitting the resale of
shares issued under those plans, options or warrants by nonaffiliates in the
public market without restriction under the Securities Act. Such registration
statement will become effective immediately upon filing. An aggregate of
1,557,027 shares of Common Stock are issuable pursuant to outstanding options
and options under the 1997 Plan. An additional 722,973 shares of Common Stock
are available for future grants under the Company's 1997 Plan.
 
    Following this Offering, the holders of       Restricted Shares and the
holders of warrants to purchase an additional       shares of Common Stock will
have the right to cause the Company to register the sale of such shares under
the Securities Act. If such registration rights are exercised, the shares can be
sold without any holding period or sales volume limitation. See "Description of
Capital Stock-- Registration Rights of Certain Holders."
 
    Prior to this Offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could adversely effect the market price of the Common Stock.

    The Underwriting Agreement provides that the obligations of the Underwriters
to purchase the Shares listed above are subject to certain conditions. The
Underwriting Agreement also provides that the Underwriters are committed to
purchase, and the Company is obligated to sell, all of the Shares offered by
this Prospectus, if any of the Shares being sold pursuant to the Underwriting
Agreement are purchased (without consideration of any shares that may be
purchased through the exercise of the Underwriters' over-allotment option).
 
    The Representatives have advised the Company that the Underwriters propose
to offer the Shares to the public initially at the public offering price set
forth on the cover page of this Prospectus and to certain dealers at such price
less a concession not in excess of $         per share. The Underwriters may
allow, and such dealers may reallow, a concession to other dealers not in excess
of $         per share. After the initial public offering of the Shares, the
public offering price, the concessions to selected dealers and the reallowance
to other dealers may be changed by the Representatives.
 
    The Company has granted to the Underwriters an option, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to an
additional       shares of Common Stock at the initial public offering price set
forth on the cover page of this Prospectus, less underwriting discounts and
commissions. The Underwriters may exercise such option only to cover
over-allotments, if any, incurred in the sale of Shares. To the extent the
Underwriters exercise such option, each of the Underwriters will become
obligated, subject to certain conditions, to purchase such percentage of such
additional shares of Common Stock as is approximately equal to the percentage of
Shares that it is obligated to purchase as shown in the table set forth above.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
    Certain officers of Unterberg Harris own in the aggregate 10,177 shares of
Common Stock of the Company.
 
    The Representatives have informed the Company that they do not intend to
confirm sales to any account over which they exercise discretionary authority.

Prospectus, and certain other stockholders holding in the aggregate       shares
of Common Stock, for a period ending one year from the date of this Prospectus,
have agreed not to offer to sell, sell, contract to sell, or grant any option to
purchase or otherwise dispose of, directly or indirectly, any shares of capital
stock of the Company or any securities convertible into or exercisable or
exchangeable for any capital stock or warrants or other rights to purchase
shares of capital stock of the Company owned by any of them prior to the
expiration of 180 days or one year from the date of this Prospectus, as the case
may be, except: (i) for the Shares offered hereby, (ii) with the prior written
consent of PaineWebber Incorporated and (iii) in the case of the Company, for
the issuance of shares of Common Stock upon the exercise of options, or the
grant of options to purchase shares of Common Stock or restricted stock awards
under the Stock Plans.
 
    Prior to this Offering, there has been no public market for the Common Stock
of the Company. The initial public offering price will be determined pursuant to
negotiations between the Company and the Representatives. Among the factors to
be considered in determining the initial public offering price, in addition to
prevailing market conditions, will be certain financial information of the
Company, the history of, and the prospects for, the Company and the industry in
which it competes, an assessment of the Company's management, its past and
present operations, the prospects for, and timing of, future revenues of the
Company, the present state of the Company's development, and the above factors
in relation to market values and various valuation measures of other companies
engaged in activities similar to the Company. The initial public offering price
set forth on the cover page of this Prospectus should not, however, be
considered an indication of the actual value of the Common Stock. Such price is
subject to change as a result of market conditions and other factors. There can
be no assurance that an active trading market will develop for the Common Stock
or that the Common Stock will trade in the public market subsequent to the
Offering at or above the initial public offering price.
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Brobeck, Phleger & Harrison LLP, New York, New York, and for the
Underwriters by Shearman & Sterling, New York, New York.

                       CHANGE IN INDEPENDENT ACCOUNTANTS
 
    On November 27, 1996, the Company dismissed Price Waterhouse LLP as its
independent accountants. The reports of Price Waterhouse LLP on the Company's
financial statements for the past two fiscal years contained no adverse opinion
or disclaimer of opinion, and were not qualified or modified as to uncertainty,
audit scope or accounting principles. In connection with its audits for the year
ended June 30, 1996 and for the period from August 17, 1994 (inception) through
June 30, 1995, and through November 27, 1996, there have been no disagreements
with Price Waterhouse LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements if not resolved to the satisfaction of Price Waterhouse LLP would
have caused them to make reference thereto in their report on the financial
statements for such years. The decision to change firms was approved by the
Company's Board of Directors. The Company has requested that Price Waterhouse
LLP furnish it with a letter addressed to the Commission stating whether or not
it agrees with the above statements. A copy of such letter, dated February 27,
1997, is filed as an exhibit to the Registration Statement of which this
Prospectus forms a part.
 
    The Company engaged Ernst & Young LLP as its new independent auditors as of
November 27, 1996.
 
    During the two most recent fiscal years and through November 27, 1996, the
Company did not consult with Ernst & Young LLP on items which (i) were or should
have been subject to Statement on Auditing Standards No. 50 or (ii) concerned
the subject matter of a disagreement or reportable event with Price Waterhouse
LLP.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders of
  Globecomm Systems Inc.
 
    We have audited the accompanying consolidated balance sheet of Globecomm
Systems Inc. at December 31, 1996 and the related consolidated statements of
operations, changes in stockholders' equity and cash flows for the six months
then ended. These consolidated financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Globecomm

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
  and Stockholders of Globecomm Systems Inc.
 
The stock split described in Note 1 to the financial statements has not been
consummated at February 26, 1997. When it has been consummated, we will be in a
position to furnish the following report:
 
    "In our opinion, the accompanying consolidated balance sheets and the
    related consolidated statements of operations, of changes in stockholders'
    equity and of cash flows present fairly, in all material respects, the
    financial position of Globecomm Systems Inc. and its subsidiary at June 30,
    1995 and 1996, and the results of their operations and their cash flows for
    the period from August 17, 1994 (inception) through June 30, 1995 and the
    year ended June 30, 1996, in conformity with generally accepted accounting
    principles. These financial statements are the responsibility of the
    Company's management; our responsibility is to express an opinion on these
    financial statements based on our audits. We conducted our audits of these
    statements in accordance with generally accepted auditing standards which
    require that we plan and perform the audit to obtain reasonable assurance
    about whether the financial statements are free of material misstatement. An
    audit includes examining, on a test basis, evidence supporting the amounts
    and disclosures in the financial statements, assessing the accounting
    principles used and significant estimates made by management, and evaluating
    the overall financial statement presentation. We believe that our audits
    provide a reasonable basis for the opinion expressed above."

$.001, to be effective prior to the closing of the planned initial public
offering ("IPO"). Effect has been given to this stock split as if it occurred on
August 17, 1994 (inception). All common share, option and warrant data has been
restated to reflect the stock split. In addition, on February 26, 1997, the
Board of Directors authorized, subject to stockholder approval, the 1997 Stock
Incentive Plan ("1997 Plan"), which will serve as a successor plan to the stock
option plans discussed in Note 8. The 1997 Plan provides for an increase of
285,000 shares to the previously existing stock option plans, among other
matters.
 
    The Company has incurred operating losses since its inception and had an
accumulated deficit at December 31, 1996 of $4,202,621. Such losses have
resulted principally from general and administrative and selling and marketing
expenses associated with the Company's operations. The Company expects that its
cash and working capital requirements will continue to increase in connection
with the Company's plans to continue to expand operations. In order to fund
these efforts, the Company completed a private placement of preferred stock in
December 1996, whereby it received net proceeds of $10,965,000. Management
believes that sufficient funding has been obtained to enable the Company to meet
its working capital needs through December 31, 1997.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the financial statements and accompanying notes. Actual
results could differ from those estimates.
 
REVENUE RECOGNITION
 
    The Company uses the percentage-of-completion method of accounting for
contract revenues, upon the achievement of certain milestones. Accordingly,
revenue from long-term, fixed-price contracts, are generally recorded based on
the relationship of total costs incurred to date to total projected final costs.
Contract costs generally include purchased material, direct labor, overhead and
other indirect costs. Anticipated contracted losses are recognized as they
become known.
 
    Revenues from sales of products and services are generally recognized when
the product is shipped or the service is performed.
 
INVENTORIES
 
    Inventories, which consists primarily of costs incurred in connection with
specific customer contracts, are stated at the lower of cost or market value.
 
CASH EQUIVALENTS
 
    The Company classifies as cash equivalents all highly liquid instruments
with a maturity of three months or less at the time of purchase.
 
FIXED ASSETS
 
    Fixed assets are stated at cost less accumulated depreciation. Depreciation
of fixed assets is provided on a straight-line basis over their estimated useful
lives of three to five years. Certain leased office equipment has been
capitalized. These amounts are included in fixed assets within the accompanying
consolidated balance sheet and are being amortized over the estimated useful
lives of the equipment.
 
RESEARCH AND DEVELOPMENT
 
    Research and development expenditures are expensed as incurred.
 
INCOME TAXES
 
    The financial statements have been prepared in conformity with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes." This
statement requires recognition of deferred income taxes under the liability
method.
 
PRO FORMA LOSS PER SHARE (UNAUDITED)
 
    Pro forma loss per share is based on the weighted average number of shares
of Common Stock outstanding assuming the conversion of the Class A and Class B
Convertible Preferred Stock into

Common Stock, which will occur upon the consummation of the Company's planned
IPO. However, in accordance with Staff Accounting Bulletin 83 of the Securities
and Exchange Commission, the stock options that were issued during the 12 months
preceding the planned IPO at prices below the estimated IPO price (assumed to be
$         per share) have been included in the Company's pro forma loss per
share computation using the treasury stock method and the estimated IPO price,
and treated as if they had been issued at the Company's inception even though
they were antidilutive. Historical losses per share have not been presented
because such amounts are not deemed meaningful due to the significant change in
the Company's capital structure which will occur in connection with the planned
IPO.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The book values of cash and cash equivalents, accounts receivable, note
receivable from stockholder, accounts payable, and accrued liabilities
approximate their fair values principally because of the short-term maturities
of these instruments. The fair value of the Company's note payable to
stockholder is estimated based on the current rates offered to the Company for
debt of similar terms and maturities. Under this method, the Company's fair
value of note payable to stockholder was not significantly different than the
stated value at June 30, 1995 and 1996 and December 31, 1996.
 
LONG-LIVED ASSETS
 
    In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("Statement
121"), which requires impairment losses to be recorded on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated by those assets are less than the assets'
carrying amount. Statement 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company has adopted Statement
121 during the six months ended December 31, 1996, and there was no effect on
the financial statements related to the adoption.

6. COMMON STOCK
 
SALES OF COMMON STOCK
 
    In June 1995, the Company completed a private placement offering in which
the Company issued 1,218,982 shares of common stock to various investors.
Proceeds from the issuance of these shares totaled $5,031,966, including

paid $669,682 in cash and issued 156,488 shares of its common stock valued at
$731,924. Additionally, in connection with this offering, the Company sold to
one of its investors for $3,751, a five-year warrant to purchase 106,901 shares
of the Company's common stock at a price of $5.26 per share. The warrant

STOCK ISSUED TO CONSULTANTS
 
    During the year ended June 30, 1996, the Company issued 9,975 shares of its
common stock to a consultant in payment for his efforts in assisting in various
Company matters. These shares were purchased by the consultant at a price of
$.04 per share. Consulting expense recorded as a result of this transaction
amounted to $46,270, which represents the difference between the fair market
value of the shares at the date of issuance and the purchase price.
 
    During November 1996, the Company issued a ten-year warrant to five
consultants for future services to purchase an aggregate of 64,125 shares of
common stock at a price per share of $8.07, equal to the fair market value of
the shares at the date of issuance.
 
ISSUANCE OF COMMON STOCK AS COMMISSION
 
    On November 9, 1995, and in connection with the Company's sale of 199,500
shares of its common stock to an investor also during the year ended June 30,
1996, the Company entered into a commitment to issue up to 5% of its share
capital as follows: (i) 1% of the then outstanding share capital of the Company

6. COMMON STOCK (CONTINUED)
    In November 1995, the Company issued 37,147 shares of its common stock to
this investor, or 1% of the then outstanding share capital. This issuance
resulted in $173,743 of commission expense based on the fair market value of the
shares at the date of issuance. As of June 30, 1996, this entire amount is
included in prepaid expenses within the accompanying consolidated balance sheet
as the related orders were not recorded as revenue during the year ended June
30, 1996. Such amount was included in selling and marketing expense in the
accompanying consolidated statement of operations for the six months ended
December 31, 1996, the period in which the related revenue was recognized.
 
7. CONVERTIBLE PREFERRED STOCK
 
    In December 1996, the Company issued 485,294 shares (including 53,152 shares
issued as commission) of its Class B convertible preferred stock ("Class B

shares totaled $10,965,000, net of related cash expenses of $1,135,000.
 
    On May 30, 1996, the Company issued 156,250 shares of its Class A
convertible preferred stock ("Class A Convertible") at $16.00 per share to
investors. Proceeds from the sale of these shares totaled $2,485,000, net of
related expenses of $15,000. In addition, during August 1996, the Company issued
16,054 shares of Class A Convertible at $16.00 per share to an investor.
 
    The principal terms of the Class A Convertible and Class B Convertible
(collectively, the "Preferred Stock") are as follows:
 
- - LIQUIDATION PREFERENCE
 
    In the event of a liquidation of the Company and before any distribution of
    assets is made to holders of common stock, the holders of the Preferred
    Stock are entitled to receive: Class A Convertible, $16.00 per share, or
    $2,756,864, and Class B Convertible, $28.00 per share or $13,588,232.
 
- - CONVERSION
 
    The holders of the Preferred Stock have the right, at any time, to convert
    such shares into common stock on a 2.85-for-1 basis, subject to certain
    anti-dilution provisions as described in the agreement. The Preferred Stock
    shall automatically convert into common stock upon notice of and prior to
    the consummation of a public offering of the Company's common stock, where
    gross proceeds from the offering are at least $7,500,000, subject to certain
    adjustment provisions as described in the Company's Certificate of
    Incorporation, as amended.

    right to vote.
 
8. STOCK OPTION PLANS
 
    The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" and related Interpretations in
accounting for its stock options because, as discussed below, the alternative
fair value accounting provided for under Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based-Compensation" ("Statement 123"),
requires the use of option valuation models that were not developed for use in
valuing employee and director stock options.
 
EMPLOYEE PLAN
 
    In February 1995, the Company adopted a stock option plan (the "Employee
Stock Option Plan"), which provides that the Company may grant employees options
to acquire up to an aggregate of 285,000 shares of the Company's common stock.
During the six months ended December 31, 1996, the Company increased the number
of shares it may grant to 1,710,000. The options generally vest in equal
installments over a four-year period and expire on the tenth anniversary of the
date of grant.
 
    The following table summarizes activity in employee stock options:

    Exercise prices for options outstanding at December 31, 1996 ranged from
$3.51 to $8.07 per share. The weighted average remaining contractual life of
those options is approximately ten years. As of December 31, 1996, options to
purchase approximately 120,000 shares of common stock are exercisable at a
weighted average exercise price of $4.27.
 
    As a result of stock options granted during the years ended June 30, 1995
and 1996, the Company recorded compensation expense of $14,237, $99,053, $49,527

1995 and 1996 and the six months ended December 31, 1995 and 1996, respectively,
based on the difference between the fair market value of the shares and the
option exercise prices at the dates of grant. As of December 31, 1996, remaining
compensation expense to be recorded through the year ended June 30, 1999 was
approximately $63,000.
 
DIRECTOR PLAN
 
    In June 1995, the Company adopted a stock option plan (the "Director Stock
Option Plan"), which provides that the Company may grant outside directors
options to acquire up to an aggregate of 285,000 shares of the Company's common
stock. The options vest annually in equal installments over a three year period
commencing on the date of grant. The options expire the earlier of five years
from the date of grant or three years from concluding service as director of the
Company.
 
    Pursuant to the Director Stock Option Plan, in June 1995, the Company
granted certain outside directors options to purchase 128,250 shares of the
Company's common stock at $3.51 per share. As a result of these grants, the
Company recorded compensation expense during the years ended June 30, 1995 and
1996, and the six months ended December 31, 1995 and 1996 of $2,081, $92,962,
$46,481 and $19,772, respectively, based on the fair market value of the shares
at the date of grant. As of December 31, 1996, remaining compensation expense to
be recorded through the year ended June 30, 1998 was approximately $35,000. As
of December 31, 1996, 64,125 options were exercisable and none were exercised.
 
STATEMENT 123
 
    Pro forma information regarding net loss and net loss per share is required
by Statement 123, which also requires that the information be determined as if
the Company has accounted for its stock options granted subsequent to July 1,
1995 under the fair value method of that Statement. The fair value for these
options was estimated using a Black-Scholes option pricing model with the
following weighted-average assumptions for the year ended June 30, 1996 and the
six months ended December 31, 1996: risk-free interest rate of 6.5%, volatility
factor of the expected market price of the Company's common stock of .40, a
weighted-average expected life of the option of six years and no dividend
yields.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its stock options.

10. PENSION PLAN
 
    During the period ended June 30, 1995, the Company established a 401(k) plan
which covers substantially all employees of the Company. Participants may elect
to contribute from 1% to 20% of their pre-tax compensation. Participant
contributions up to 4% of pre-tax compensation were fully matched by the Company
during the years ended June 30, 1995 and 1996 and the six months ended December
31, 1995 and 1996. The plan also provides for discretionary contributions by the
Company. The Company contributed $8,967, $41,883, $11,896 and $42,994 to the
plan during the years ended June 30, 1995 and 1996 and the six months ended

income tax return at December 31, 1996, it would have available net operating
loss carryforwards of approximately $3,100,000 for income tax purposes which
expire through 2012.
 
    As the Company has had cumulative losses and there is no assurance of future
taxable income, a valuation allowance has been established to offset deferred
tax assets. The components of the Company's net deferred tax assets are as
follows:

customers' financial condition and in most cases requires a letter of credit or
cash in advance for foreign customers. Historically, the Company has not
incurred significant losses from trade receivables.
 
    Sales to two major customers accounted for approximately 61% (43% and 18%)
of the Company's net revenues for the year ended June 30, 1996, and 86% (53% and
33%) and 33% (17% and 16%) of net revenues for the six months ended December 31,
1995 and 1996, respectively.
 
    Revenues from foreign sales accounted for 22% (13% Europe, 5% Africa and 4%
Asia), 5% (Asia) and 59% (43% Asia, 13% Europe and 3% Africa) of total revenues
for the year ended June 30, 1996 and the six months ended December 31, 1995 and
1996, respectively.
 
    Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and trade receivables.
The Company places its cash and cash equivalents with high quality financial
institutions and, by policy, limits the amount of credit exposure to any one
institution. Cash equivalents are comprised of short-term debt instruments,
certificates of deposit or direct or guaranteed obligations of the United
States, which are held to maturity and approximate cost. At times, cash may be
in excess of FDIC insurance limits.
 
13. COMMITMENTS
 
LINE OF CREDIT
 
    As of December 31, 1996, the Company maintains a secured line of credit of
$1,500,000, which expires on January 31, 1997. Borrowings under this line bear
interest at the then prime rate and are secured by certain assets of the Company
in addition to a personal guarantee by the Company's chief executive officer,
who is also a stockholder of the Company. Through December 31, 1996, there were
no borrowings made under this line.
 
    During January 1997, the Company received a one year, $5,000,000 proposed
credit facility from a bank. The proposed facility is to support the working
capital requirements of the Company and for the issuance of letters of credit.
The proposed facility will provide for interest at the prime rate plus 1/2% per
annum and will be collateralized by a first security interest on all assets.
Prior to closing of the proposed facility, the bank will complete its due
diligence inquiry of the Company, including an accounts receivable review, as
defined.
 
LETTERS OF CREDIT
 
    The Company utilizes standby letters of credit to secure certain bid
proposals and performance guarantees in the normal course of business. The
Company provides cash collateral for all of these letters of credit. As of June
30, 1995 and 1996 and December 31, 1996, cash collateral related to bid
proposals amounted to $96,000, $1,043,000 and $1,270,625, respectively, and cash
collateral related to performance guarantees amounted to zero, $188,850 and
$344,861, respectively. These amounts are included in restricted cash in the
accompanying consolidated balance sheet.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law authorizes a court to

directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Act"). Article 7 of the Registrant's Amended and Restated
Certificate of Incorporation provides for indemnification of its directors and
officers and permissible indemnification of employees and other agents to the
maximum extent permitted by the Delaware General Corporation Law. Reference is
also made to Section       of the Underwriting Agreement contained in Exhibit
1.1 hereto, which sets forth certain indemnification provisions. The Registrant
has obtained liability insurance for its officers and directors.

ITEM 17. UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes to provide to the Underwriter,
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation of the Registrant, the Underwriting Agreement, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action,
 
                                      II-3
<PAGE>
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
    The undersigned Registrant hereby undertakes:
 
    (1) That for purposes of determining any liability under the Act, the
information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
Prospectus filed by the Registrant pursuant to Rule 424 (b) (1) or (4), or 497
(h) under the Act shall be deemed to be part of this Registration Statement as
of the time it was declared effective.
 
    (2) That for the purpose of determining any liability under the Act, each
post-effective amendment that contains a form of Prospectus shall be deemed to
be a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

definition, limitation and regulation of the powers of the corporation and of
its directors and stockholders:

SEVENTH: Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this

jurisdiction within the State of Delaware, may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this corporation under the provisions of Section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in

any reorganization of this corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization

                             WORLDCOMM SYSTEMS INC.
           CERTIFICATE OF DESIGNATION OF RELATIVE RIGHTS, PREFERENCES,
                          PRIVILEGES AND RESTRICTIONS

     The undersigned, President of Worldcomm Systems, Inc., a Delaware
corporation (the "Corporation"), hereby certifies and sets forth the following.

     Pursuant to the authority contained in Article FOURTH of the Certificate of
Incorporation, the Board of Directors has adopted the following resolution to
authorize the issuance of a class of the Corporation's Preferred Stock, par
value $.01 per share, and to fix the preferences and relative, participating,
optional or other special rights, and qualifications, limitations or
restrictions thereof.

          RESOLVED, that pursuant to the authority granted by Article FOURTH of
     the Certificate of Incorporation, the Board of Directors authorizes
     issuance of a new class of the Corporation's Preferred Stock, par value
     $.01 per share, having the following designation and preferences and
     relative, participating, optional or other special rights, and
     qualifications, limitations or restrictions thereof.

          This class is designated Class A Preferred Stock.

          The number of shares which shall initially constitute the Class A
     Preferred Stock is 156,250 shares.

          At the option of the holder thereof, each share of Class A Preferred
     Stock shall be convertible, at any time or from time to time, into the
     number of fully paid and nonassessable share of Common Stock which results
     from dividing $16.00 by the conversion price which is in effect at the time
     of conversion (the "Conversion Price"). The Conversion Price shall be
     subject to adjustment from time to time as provided below.

          If the Corporation shall (i) issue additional shares of Common Stock
     as a dividend or other distribution on outstanding Common Stock, (ii)
     subdivide the outstanding shares of Common Stock into a greater number of
     shares of Common Stock or (iii) combine the outstanding shares of Common
     Stock into a smaller number of shares of Common Stock, then upon the
     happening of such event, the Conversion Price of the Class A Preferred
     Stock shall be adjusted by multiplying the Conversion Price in effect
     immediately prior to such event by a fraction, the numerator of which is
     the number of shares of Common Stock issued and outstanding immediately
     prior to such event, and the denominator of which is the number of shares
     of Common Stock issued and outstanding immediately after such event. The
     product so obtained shall thereafter be the Conversion Price for the Class
     A Preferred Stock.

               If at any time or from time to time the Corporation shall pay a
     dividend or make another distribution to holders of the Common Stock
     payable in securities of the Corporation other than shares of Common 

<PAGE>

     Stock, then in each such event the Corporation shall make provision so that
     holders of the Class A Preferred Stock shall receive upon conversion
     thereof, in addition to the number of shares of Common Stock receivable
     upon conversion thereof, the amount of securities of the Corporation which
     they would have received had their Class A Preferred Stock been converted
     into Common Stock on the date of such event and had they thereafter, during
     the period from the date of such event to and including the conversion
     date, retained such securities receivable by them as aforesaid during such
     period, subject to all other adjustments called for during such period
     under this Section (c) with respect to rights of the holders of the Class A
     Preferred Stock or with respect to such other securities by their terms.

               Each holder of Class A Preferred Stock who elects to convert the
     same into shares of Common Stock shall surrender the certificate or
     certificates therefor, duly endorsed, at the office of the Corporation or
     any transfer agent for the Class A Preferred Stock or Common Stock, and
     shall give written notice to the Corporation at such office that such
     holder elects to convert the same and shall state therein the number of
     shares of Class A Preferred Stock being converted. Thereupon, the
     Corporation shall promptly issue and deliver at such office to such holder
     a certificate or certificates for the number of shares of Common Stock to
     which such holder is entitled upon such conversion. Such conversion shall
     be deemed to have been made immediately prior to the close of business on
     the date of such surrender of the certificate or certificates representing
     the shares of Class A Preferred Stock to be converted, and the person
     entitled to receive the shares of Common Stock issuable upon such
     conversion shall be treated for all purposes as the record holder of such
     shares of Common Stock on such date.

               No fractional shares of Common Stock shall be issued upon any
     conversion of Class A Preferred Stock. In lieu of any fractional share to
     which the holder would otherwise be entitled, the Corporation shall pay the
     holder cash equal to be product of such fraction multiplied by the Common
     Stock's fair market value as determined in good faith by the Corporation's
     Board of Directors as of the date of conversion.

               The Corporation shall at all times reserve and keep available out
     of its authorized but unissued shares of Common Stock, solely for the
     purpose of effecting the conversion of the shares of Class A Preferred
     Stock, such number of its shares of Common Stock as shall from time to time
     be sufficient to effect the conversion of all outstanding shares of Class A
     Preferred Stock; and if at any time the number of authorized but unissued
     shares of Common Stock shall not be sufficient to effect the conversion of
     all been outstanding shares of Class A Preferred Stock, the Corporation
     will take such corporate action as may, in the opinion of its 

<PAGE>

     counsel, be necessary to increase its authorized but unissued shares of
     Common Stock to such number of shares as shall be sufficient for such
     purpose.

               The Corporation shall not avoid or seek to avoid the observance
     or performance of any of the terms to be observed or performed hereunder by
     the Corporation, but shall at all times in good faith assist in carrying
     out all such actions as may be reasonably necessary or appropriate in order
     to protect the conversion price of the holders of the Class A Preferred
     Stock against impairment.

          Each share of Class A Preferred Stock shall automatically be converted
     into fully paid and nonassessable shares of Common Stock, as provided
     herein immediately prior to the closing of a firm commitment underwritten
     public offering pursuant to an effective registration statement under the
     Securities Act of 1933, as amended, covering the offer and sale of Common
     Stock for the account of the Corporation in which the aggregate public
     offering price (before deduction of underwriters' discounts and
     commissions) equals or exceeds $7,500,000. Such conversion shall occur
     whether or no the certificates evidencing the shares so converted are
     surrendered to the Corporation or its transfer agent. However, the
     Corporation shall not be obligated to issue certificates evidencing the
     shares of Common Stock issuable upon such conversion unless the
     certificates evidencing such shares of Class A Preferred Stock are either
     delivered to the Corporation or its transfer agent as provided below, or
     the holder notifies the Corporation or its transfer agent that such
     certificates have been lost, stolen or destroyed and executes an agreement
     satisfactory to the Corporation to indemnify the Corporation from any loss
     incurred by it in connection with such certificates. Upon the occurrence of
     such automatic conversion of Class A Preferred Stock, the holders of such
     Preferred Stock shall surrender the certificates evidencing such shares at
     the office of the Corporation or any transfer agent for the Class A
     Preferred Stock or Common Stock. Thereupon, there shall be issued and
     delivered to such holder promptly at such office and in its name as shown
     on such surrendered certificate or certificates, a certificate or
     certificates for the number of shares of Common Stock into which the shares
     of Class A Preferred Stock so surrendered were convertible on the date on
     which such automatic conversion occurred.

          Except as otherwise required by law, each holder of the Class A
     Preferred Stock shall be entitled to one vote for each share of Common
     Stock into which the Preferred Stock held by such holder is at the time
     reference convertible. Holders of the Class A Preferred Stock shall vote as
     a single class with holders of the Common Stock on all matters upon which a
     vote of stockholders is authorized or required by law or by the Certificate
     of Incorporation.


<PAGE>

          Holders of the Class A Preferred Stock shall be entitled to
     participate ratably, based on the number of shares of Common Stock into
     which the such holder's shares of Class A Preferred Stock are then
     convertible, with holders of the Common Stock in any dividends or other
     distributions which may be declared upon or paid to holders of the Common
     Stock.

          In the event of the dissolution, liquidation or winding up of the
     Corporation, or a sale of all of its assets, whether voluntary or
     involuntary, or in the event of its insolvency, there shall be paid to the
     holders of the Preferred Stock the sum of $16.00 per share, before any sums
     shall be paid or any assets distributed among holders of the Common Stock.
     If the assets of the Corporation shall be insufficient to permit the
     payment in full to the holders of the Preferred Stock of the amount thus
     distributable, then the entire assets of the Corporation shall be
     distributed ratably among the holders of the Preferred Stock. After the
     foregoing up to the holders of the Preferred Stock, the remaining assets
     and funds of the Corporation shall be distributed among and paid to the
     holders of the Common Stock and the Preferred Stock, share and share alike,
     in proportion to their stockholdings.

          If the Corporation proposes at any time to issue additional voting
     securities for payment in cash, the Corporation shall give holders of the
     Class A Preferred Stock prompt written notice of such proposal, including
     information regarding (i) the number and class or series of the securities
     proposed to be sold (the "Offered Securities"), and, if such securities
     will be of a new class, the rights, preferences and restrictions applicable
     to such new class, (ii) if known, the identity of any proposed third party
     acquiror or acquirors of the proposed Offered Securities, (iii) the price
     per security at which the Corporation proposes to sell the Offered
     Securities (the "Offer Price") and (iv) the proposed terms of payment and
     other material terms and conditions of the proposed sale. Subject to the
     provisions set forth below, each holder of the Class A Preferred Stock held
     have a preemptive right to purchase such holder's Pro Rata Part (as
     hereinafter defined) of the Offered Securities at the Offer Price and on
     the other terms and conditions set forth in the notice. "Pro Rata Part"
     shall mean the proportion which the number of votes which the holder is
     entitled to cast by reason of his ownership of Class A Preferred Stock
     bears to the number of votes which holders of all voting securities
     (including such holder) are entitled to cast immediately prior to the date
     subscriptions are opened for such offering. In order to exercise such
     preemptive rights, such holder must notify the Corporation in writing not
     later than fifteen (15) days after receipt by the holder of the
     Corporation's notice. Such notice from the holder shall state the number of

<PAGE>

     securities which the holder desires to purchase, and shall be deemed an
     irrevocable commitment on the part of such holder to purchase the number of
     securities set forth therein for the Offer Price and upon the other terms
     and conditions set forth in the Corporation's notice. The preemptive right
     set forth above shall not apply to:

                    shares of the Corporation's Common Stock (or options or
     warrants therefor) issued to employees, officers or directors of or
     consultants to, the Corporation pursuant to incentive agreements or plans
     approved by the Board of Directors of the Corporation;

                    any securities issuable upon conversion of or with respect
     to any then outstanding shares of Class A Preferred Stock of the
     Corporation or Common Stock or other securities issuable upon conversion
     thereof;

                    any securities issuable upon exercise of any options,
     warrants or rights to purchase any securities of the Corporation
     outstanding on the date of issuance of such Class A Preferred Stock
     ("Warrant Securities") and any securities issuable upon the conversion of
     any Warrant Securities;

     preferences, privileges or restrictions of such Class or increase the total
     number of authorized shares of such Class:

               reclassify any outstanding shares or securities of the
     corporation into shares having rights, preferences or privileges senior to
     such Class; or

                              WORLDCOMM SYTEMS INC.

          CERTIFICATION OF DESIGNATION OF RELATIVE RIGHTS, PREFERENCES,
                          PRIVILEGES AND RESTRICTIONS

     The undersigned, President of Worldcomm Systems, Inc., a Delaware
corporation (the "Corporation"), hereby certifies and sets forth the following.

1.   Pursuant to the authority contained in Article FOURTH of the Certificate of
     Incorporation, the Board of Directors has adopted the following resolution
     to authorize the issuance of a class of the Corporation's Preferred Stock,
     par value $.01 per share, and to fix the preferences and relative,
     participating, optional or other special rights, and qualifications,
     limitations or restrictions thereof.

     RESOLVED, that pursuant to the authority granted by Article FOURTH of the
Certificate of Incorporation, the Board of Directors authorizes issuance of a
new class of the Corporation's Preferred Stock, par value $.01 per share, having
the following designation and preferences and relative, participating, optional
or other special rights, and qualifications, limitations or restrictions
thereof.

     (a)  This class is designated Class B Preferred Stock.
     (b)  The number of shares which shall initially constitute the Class B
          Preferred Stock is 714,400 shares.
     (c)  At the option of the holder thereof, each share of Class B Preferred
          Stock shall be convertible, at any time or from time to time, into the
          number of fully paid and nonassessable shares of Common Stock which
          results from dividing $28.00 by the conversion price which is in
          effect at the time of conversion (the "Conversion Price"). The
          Conversion Price shall be subject to adjustment from time to time as
          provided below.

                    (i) If the Corporation shall (1) issue additional shares of
               Common Stock as a dividend or other distribution on outstanding
               Common Stock, (2) subdivide the outstanding shares of Common
               Stock into greater number of Common Stock, or (3) combine the
               outstanding shares of Common Stock into a smaller number of
               shares of Common Stock, then upon the happening of such event,
               the Conversion Price of the Class B Preferred Stock shall be
               adjusted by multiplying the Conversion Price in effect
               immediately prior to such event by a fraction, the numerator of
               which is the number of shares of Common Stock issued and
               outstanding immediately prior to such event, and the denominator
               of which is the number of shares of Common Stock issued and
               outstanding immediately after such event. The product so obtained
               shall thereafter be the Conversion Price for the Class B
               Preferred Stock.

                    (ii) If at any time or from time to time the Corporation
               shall pay a dividend or make another distribution to holders of
               the Common Stock payable in securities of the Corporation other
               than shares of Common Stock, then in each such event the
               Corporation shall make provision so that holders of the Class B
               Preferred Stock shall receive upon conversion thereof, in
               addition to the number of shares of Common Stock receivable upon
               conversion thereof, the amount of securities of the Corporation
               which they would have received had their Class B

<PAGE>

               Preferred Stock been converted into Common Stock on the date of
               such event and had they thereafter, during the period from the
               date of such event to and including the conversion date, retained
               such securities receivable by them as aforesaid during such
               period, subject to all other adjustment called for during such
               period under this Section (c) with respect to rights of the
               holders of the Class B Preferred Stock or with respect to such
               other securities by their terms.

                    (iii) Each holder of Class B Preferred Stock who elects to
               convert the same into shares of Common Stock shall surrender the
               certificate or certificates therefor, duly endorsed, at the
               office of the Corporation or any transfer agent for the Class B
               Preferred Stock or Common Stock and shall give written notice to
               the Corporation at such office that such holder elects to convert
               the same and shall state therein the number of shares of Class B
               Preferred Stock being converted. Thereupon, the Corporation shall
               promptly issue and deliver at such office to such holder a
               certificate or certificates for the number of shares of Common
               Stock to which such holder is entitled upon conversion. Such
               conversion shall be deemed to have been made immediately prior to
               the close of business on the date of such surrender of the
               certificate or certificates representing the shares of Class B
               Preferred Stock to be converted, and the person entitled to
               receive the shares of Common Stock issuable upon such conversion
               shall be treated for all purposes as the record holder of such
               shares of Common Stock on such date.

                    (iv) No fractional shares of Common Stock shall be issued
               upon any conversion of Class B Preferred Stock. In lieu of any
               fractional share to which the holder would otherwise be entitled,
               the Corporation shall pay the holder cash equal to be product of
               such fraction multiplied by the Common Stock's fair market value
               as determined in good faith by the Corporation's Board of
               Directors as of the date of conversion.

                    (v) The Corporation shall at all times reserve and keep
               available out of its authorized but unissued shares of Common
               Stock, solely for the purpose of effecting the conversion of the
               shares of Class B Preferred Stock, such number of its shares of
               Common Stock as shall from time to time be sufficient to effect
               the conversion of all outstanding shares of Class B Preferred
               Stock, and if at any time the number of authorized but unissued
               shares of Common Stock shall not be sufficient to effect the
               conversion of all then outstanding shares of Class B Preferred
               Stock, the Corporation will take such corporate action as may, in
               the opinion of its counsel, be necessary to increase its
               authorized but unissued shares of Common Stock to such number of
               shares as shall be sufficient for such purpose.

                    (vi) The corporation shall not avoid or seek to avoid the
               observance or performance of any of the terms to be observed or
               performed hereunder by the Corporation, but shall at all times in
               good faith assist in carrying out all such actions as may be
               reasonably necessary or appropriate in order to protect the
               conversion price of the holders of 

<PAGE>

               the Class B Preferred Stock against impairment.

     (d)  Each share of Class B Preferred Stock shall automatically be converted
          into fully paid and nonassessable shares of Common Stock, as provided
          herein immediately prior to the closing of a firm commitment
          underwritten public offering pursuant to an effective registration
          statement under the Securities Act of 1933, as amended, covering the
          offer and sale of Common Stock for the account of the Corporation in
          which the aggregate public offering price (before deduction of
          underwriters' discounts and commissions) equals or exceeds $7,500,000.
          Such conversion shall occur whether or not certificates evidencing the
          shares so converted are surrendered to the Corporation or its transfer
          agent. However, the Corporation shall not be obligated to issue
          certificates evidencing the shares of Common Stock issuable upon such
          conversion unless the certificates evidencing such shares of Class B
          Preferred Stock are either delivered to the Corporation or its
          transfer agent as provided below, or the holder notifies the
          Corporation or its transfer agent that such certificates have been
          lost, stolen or destroyed and executes an agreement satisfactory to
          the Corporation to indemnify the Corporation from any loss by it in
          connection with such certificates. Upon the occurrence of such
          automatic conversion of Class B Preferred Stock, the holder of such
          Preferred Stock, shall surrender the certificates evidencing such
          shares at the office of the Corporation or any transfer agent for the
          Class B Preferred Stock or Common Stock. Thereupon, there shall be
          issued and delivered to such holder promptly at such office and in its
          name as shown on such surrendered certificate or certificates, a
          certificate or certificates for the number of shares of Common Stock
          into which the shares of Class B Preferred Stock so surrendered were
          convertible on the date on which such automatic conversion occurred.

     (e)  Except as otherwise required by law, each holder of the Class B
          Preferred Stock shall be entitled to one vote for each share of Common
          Stock into which the Preferred Stock held by such holder is at the
          time of reference convertible. Holders of the Class B Preferred Stock
          shall vote as a single class with holders of the Common Stock on all
          mattters upon which a vote of stockholders is authorized or required
          by law by the Certificate of Incorporation.

     (f)  Holders of the Class B Preferred Stock shall be entitled to
          participate ratably, based on the number of shares of Common Stock
          into which some holder's shares of Class B Preferred Stock are then
          convertible, with holders of the Common Stock in any dividends or
          other distributions which may be declared upon or paid to holders of
          the Common Stock.

     (g)  In the event of the dissolution, liquidation or winding up of the
          Corporation, or a sale of all its assets, whether voluntary or
          involuntary, or in the event of its insolvency, there shall be paid to
          the holders of the Preferred Stock the sum of $28.00 per share, before
          any sums shall be paid or any assets distributed among holders of the
          Common Stock. If the assets of the Corporation shall be insufficient
          to permit the payment in full to the holders of the Preferred Stock of
          the amount thus distributable, then the entire assets of the
          Corporation shall be distributed ratably among the holders of the
          Preferred Stock. After the foregoing payment to the holders of the
          Preferred Stock, the remaining assets and funds of the Corporation
          shall be distributed among and paid to the holders of the Common Stock
          and the Preferred Stock, share and share alike, in proportion to their
          stockholdings.

     (h)  The Class B Preferred Stock shall not be redeemable.

     (i)  There shall not be any sinking fund for the redemption of the Class B
          Preferred Stock.

     (j)  The approval, by vote or written consent, of the holders of a majority
          of the outstanding shares of Class B Preferred Stock shall be required
          to:

                    (1)  take any action which would alter or change any of the
                         rights, preferences, privileges or restrictions of such
                         Class or increase 


<PAGE>

                         the total number of authorized shares of such Class;
                    (2)  reclassify any outstanding shares or securities of the
                         corporation into shares having rights, preferences or
                         privileges senior to such Class; or
                    (3)  authorize or issue any other stock having rights or
                         preferences senior to such Class.

     (k)  Except as expressly provided above, or above, or as required by law,
          the preferences and relative, participating, optional or other special
          rights, and qualifications, limitations or restrictions thereof
          granted to or imposed upon the Common Stock and the Class B Preferred
          Stock, or the holders thereof, shall be in all respects identical.

2.   The foregoing resolution was duly adopted at a meeting of the Board of
     Directors held on Sept. 19, 1996.

     IN WITNESS of the foregoing I have executed this certificate this 17
day of November, 1996.

require such list of stockholders to be produced as evidence of the right of the
persons challenged to vote at such meeting, and all persons who appear from such
list to be stockholders entitled to vote thereat may vote at such meeting.

      Section 2.4. Notice of Meetings. Written notice of each annual and special
meeting of stockholders, other than any meeting for which the giving of notice

therein.

      Notice of any meeting need not be given to any stockholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting. The attendance of any stockholder at a meeting, in person or by proxy,
shall constitute a waiver of notice by him except where the person is attending
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of stockholders, directors or committee of directors
need be specified in any written waiver of notice.

      Section 2.5. Adjourned Meeting and Notice Thereof. Any meeting of
stockholders may be adjourned to another time or place, and the Corporation may
transact at any adjourned meeting any business which might have been transacted
on the original date of the meeting. Notice need not be given of the adjourned

such notice shall be given to each stockholder of record entitled to vote at the
adjourned meeting in the manner prescribed in Section 2.4.

      Section 2.6. Quorum. At any meeting of stockholders, except as otherwise
expressly required by law or the Certificate of Incorporation, the holders of a
majority of the shares entitled to vote at such meeting shall constitute a
quorum for the transaction of any business, provided that when a specified item
of business is required to be voted on by a class or series, voting as a class,
the holders of a majority of the shares of such class or series shall constitute
a quorum for the transaction of such specified item of business. In the absence
of a quorum, the stockholders present may adjourn such meeting. When a quorum is
once present to organize a meeting, the quorum is not broken by the subsequent
withdrawal of any stockholders.

      Section 2.7. Voting. Every stockholder of record shall be entitled, at
every meeting of stockholders, to one (1) vote for every share standing in his
name on the record of stockholders of the Corporation unless otherwise provided
in the Certificate of Incorporation. Directors shall, unless otherwise required
by law or by the Certificate of Incorporation, be elected by a plurality of the
votes cast at a meeting of stockholders by the holders of shares entitled to
vote thereon. Whenever any corporate action, other than the election of
directors, is to be taken by vote of the stockholders, it shall, except as
otherwise required by law or by the Certificate of Incorporation, be authorized
by a majority of the votes cast at a meeting of stockholders by the holders of
shares entitled to vote thereon.

      Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent without a meeting may authorize another person or
persons to act for him by proxy. Every proxy must be signed by the stockholder
or his attorney-in-fact. No proxy shall be valid after the expiration of three
(3) years from the date thereof, unless otherwise provided in the proxy. Every
proxy shall be revocable at the pleasure of the stockholder executing it, except

person presiding thereat.

      Section 2.8. Voting Rights of Certain Shares. Neither treasury shares nor
shares held by another corporation, if a majority of the shares entitled to vote
in the election of directors of such other corporation is held by the
Corporation, shall be counted for quorum purposes or entitled to vote. Shares
held by an administrator, executor, guardian, conservator, committee, or other
fiduciary, except a trustee, may be voted by him, either in person or by proxy,
without transfer of such shares into his name. Shares held by a trustee may be
voted by him, either in person or by proxy, only after the shares have been
transferred into his name as trustee or into the name of his nominee. A
stockholder whose shares are pledged shall be entitled to vote such until the
shares have been transferred into the name of the pledgee, or a nominee of the
pledgee.

      Section 2.9. Action by Consent of Stockholders. Whenever a vote of
stockholders at a meeting thereof is required or permitted to be taken in
connection with any corporate action by any provision of statute or of the
Certificate of Incorporation or these By-Laws, the meeting, prior notice thereof
and vote of stockholders may be dispensed with if the holders of shares having
not less than the minimum number of votes that would have been necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted shall consent in writing to the taking of such
action. Where corporate action is taken in such manner by less than unanimous
written consent, prompt written notice of the taking of such action shall be

at a meeting of the Board of Directors which authorizes the contract or
transaction. In the absence of a quorum, a majority of the directors present may
adjourn the meeting until a quorum shall be present.

greater number.

      Section 5.6. Cancellation. Each certificate for capital stock surrendered
to the Corporation for exchange or transfer shall be canceled and no new
certificate or certificates shall be issued in exchange for any existing
certificate (other than pursuant to Section 5.7) until such existing certificate
shall have been canceled.

      Section 5.7. Lost, Destroyed, Stolen and Mutilated Certificates. In the
event that any certificate for shares of capital stock of the Corporation shall
be mutilated, the Corporation shall issue a new certificate in place of such
mutilated certificate. In case any such certificate shall be lost, stolen or
destroyed, the Corporation may, in the discretion of the Board of Directors or a
committee designated thereby with power so to act, issue a new certificate for
capital stock in the place of any such lost, stolen or destroyed certificate.
The applicant for any substituted certificate or certificates shall surrender
any mutilated certificate or, in the case of any lost, stolen or destroyed
certificate, furnish satisfactory proof of such loss, theft or destruction of
such certificate and of the ownership thereof. The Board of Directors or such
committee may, in its discretion, require the owner of a lost, stolen or
destroyed certificate, or his representatives, to furnish to the Corporation a
bond with an acceptable surety or sureties and in such sum as will be sufficient
to indemnify the Corporation against any claim that may be made against it on
account of the lost, stolen or destroyed certificate or the issuance of such new
certificate. A new certificate may be issued without requiring a bond when, in
the judgment of the Board of Directors, it is proper to do so.

      Section 5.8. Fixing of Record Date. (a) The Board of Directors may fix, in
advance, a record date, which shall not be more than sixty (60), nor less than
ten (10), days before the date of any meeting of stockholders, nor more than
sixty (60) days prior to any other action, for the purpose of determining
stockholders entitled to notice of or to vote at such meeting of stockholders or
any adjournment thereof, or to express consent or dissent to corporate action in
writing without a meeting, or to receive payment of any dividend or allotment of
any rights, or for the purpose of any other action, except that where the matter
to be acted on is a merger or consolidation of the Corporation or a sale, lease
or exchange of all or substantially all of its assets, such date shall be not
less than twenty nor more than sixty days prior to such meeting.

      (b) If no record date is fixed by the Board of Directors:

            (i) The record date for determining stockholders entitled to notice
of or to vote at a meeting of stockholders shall be at the close of business on
the next day preceding the day on which notice is given, or if no notice is
given, the day on which the meeting is held;

            (ii) The record date for determining stockholders for any purpose
other than that specified in subparagraph (i) shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto.

      (c) A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting,
provided that the Board of Directors may fix a new record date for the adjourned
meeting.

                          ARTICLE VI - INDEMNIFICATION

      Section 6.1. Indemnification. The Corporation shall indemnify any person
made, or threatened to be made, a party to an action or proceeding (including
one by or in the right of the Corporation to procure a judgment in its favor),
whether civil or criminal, including, but not limited to, an action by or in the
right of any other corporation of any type or kind, domestic or foreign, or any
partnership, joint venture, trust, employee benefit plan or other enterprise,
which any director or officer of the Corporation served in any capacity at the
request of the Corporation, by reason of the fact that he, his testator or
intestate, was a director or officer of the Corporation, or served such other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise in any capacity, against judgments, fines, amounts paid in settlement
and reasonable expenses, including, but not limited to, attorneys' fees incurred
as a result of such action or proceeding, or any appeal therein, provided that
no indemnification shall be made to or on behalf of any director or officer of
the Corporation if a judgment or other final adjudication adverse to the
director or officer establishes that his acts were committed in bad faith or
were the result of active and deliberate dishonesty and were material to the
cause of action so adjudicated, or that he personally gained in fact a financial
profit or other advantage to which he was not legally entitled.

      The Corporation shall he deemed to have requested a person to serve an
employee benefit plan where the performance by such person of his duties to the
Corporation also imposes duties on, or otherwise involves services by, such
person to the plan or participants or beneficiaries of the plan; excise taxes
assessed on a person with respect to an employee benefit plan pursuant to
applicable law shall be considered fines.

      Expenses incurred in connection with a civil or criminal action or
proceeding may be paid by the Corporation in advance of the final disposition of
any such action or proceeding upon 

<PAGE>

receipt of an undertaking by or on behalf of the director or officer to repay
the expenses so advanced, if the director or officer is ultimately found not to
be entitled to indemnification, and where the director or officer is ultimately
found to be entitled to some indemnification, to the extent the expenses so
advanced exceed the indemnification to which the director or officer ultimately
is found to be entitled.

      Notwithstanding the failure of the Corporation to provide indemnification,
and despite any contrary resolution of the Corporation's Board of Directors or
of the Corporation's stockholders in any specific case arising under the
Delaware General Corporation Law, indemnification shall be awarded by a court to
the maximum extent permitted under these By-laws. Application therefor may be
made, in every case, either:

            (i) In. the civil action or proceeding in which the expenses were
incurred or other amounts were paid, or

            (ii) To a court in a separate proceeding, in which case the
application shall set forth the disposition of any previous application made to
any court for the same or similar relief and also reasonable cause for the
failure to make application for such relief in the action or proceeding in which
the expenses were incurred or other amounts were paid.

      (a) The application shall be made in such manner and form as may be
required by the applicable rules of court or, in the absence thereof, by
direction of a court to which it is made. Such application shall be upon notice
to the Corporation. The court may also direct that notice be given at the
expense of the Corporation to the Corporation's stockholders and such other
persons as it may designate in such manner as it may require.

      (b) Where indemnification is sought by judicial action, the court may
allow a person such reasonable expenses, including attorneys' fees, during the
pendency of the litigation as are necessary in connection with his defense
therein.

      All expenses incurred defending a civil or criminal action or proceeding
which are allowed by a court under paragraph (b) above, shall be repaid in case
the director or officer receiving such allowance is ultimately found not to be
entitled to indemnification, and where the director or officer is ultimately
found to be entitled to some indemnification, to the extent the expenses so
allowed by the court exceed the indemnification to which the director or officer
ultimately is found to be entitled.

      Any indemnification by the Corporation pursuant hereto shall only be made
in the manner and to the extent authorized by applicable law, but shall be made
to the maximum extent permitted by applicable law, and such indemnification
shall not be deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.

      Section 6.2. Indemnification Insurance. To the extent permitted by law,
the Corporation shall have power to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such.

                     ARTICLE VII - MISCELLANEOUS PROVISIONS

      Section 7.1. Corporate Seal. The seal of the Corporation shall be circular
in form with the name of the Corporation in the circumference and the words and
figures "Corporate Seal - 1994, Delaware" in the center. The seal may be used by
causing it to be affixed or impressed, or a facsimile thereof may be reproduced

bill so exchange, notes or other obligations or orders for the payment of money
shall be signed in the name of the Corporation by such officer or officers or
person or persons, as the Board of Directors may from time to time designate.
Except as otherwise provided by law, the Board of Directors, any committee given
specific authority in the premises by the Board of Directors, or any committee
given authority to exercise generally the powers of the Board of Directors,
during the intervals between meetings of the Board of Directors, may authorize
any officer, employee or agent, in the name of and on behalf of the Corporation,
to enter into or execute and deliver deeds, bonds, mortgages, contracts and
other obligations or instruments, and such authority may be general or confined
to specific instances.

      All applications, written instruments and papers required by any
department of the United States Government or by any state, county, municipal or
other governmental authority, may be executed in the name of the Corporation by
any principal officer or subordinate officer of the Corporation, or, to the
extent designated for such purpose from time to time by the Board of Directors,
by an employee or agent of the Corporation. Such designation may contain the
powers to substitute, in the discretion of the person named, one (1) or more
other persons.

                            ARTICLE VIII - AMENDMENTS

      Section 8.1. By Stockholders. These By-Laws may be amended or repealed, or
new By-Laws may be adopted, at any meeting of stockholders.

have other offices at such places within or without the State of Delaware as the
Board of Directors may from time to time designate or the business of the
Corporation may require.

                      ARTICLE II - MEETING OF STOCKHOLDERS

      Section 2.1. Annual Meeting. The annual meeting of the stockholders of the
Corporation for the election of directors and for the transaction of such other
business as may properly come before the meeting shall he held at the principal
office of the Corporation in the State of New York, or at such other place
within or without the State of Delaware as the Board of Directors may fix, at 10
o'clock a.m., local time, on August 15 of each year, commencing with the year
1995, or at such other time and date as the Board of Directors may fix.

       Section 2.2. Special Meetings. Special meetings of stockholders,
unless otherwise prescribed by law, may be called at any time by the Board of
Directors, by the Chief Executive Officer or by order of the Board of Directors
pursuant to the written request of the holders of at least fifty percent (50%)
of the outstanding stock of the Corporation. At any special meeting, only such
business may be transacted as is related to the purpose or purposes set forth in
the notice required by Section 2.4. Special meetings of stockholders shall be
held at such place within or without the State of Delaware as shall be
designated in the notice of meeting.

      Section 2.3. List of Stockholders Entitled to Vote. A list of stockholders
as of the record date, determined pursuant to Section 5.8 and certified by the
corporate officer responsible for its preparation or by the Corporation's
transfer agent, shall be produced at any meeting of stockholders upon request of
any stockholder thereat or prior thereto. If the right to vote at any meeting is
challenged, the inspectors of election, or person presiding thereat, shall
require such list of stockholders to be produced as evidence of the right of the
persons challenged to vote at such meeting, and all persons who appear from such
list to be stockholders entitled to vote thereat may vote at such meeting.

      Section 2.4. Notice of Meetings. Written notice of each annual and special
meeting of stockholders, other than any meeting for which the giving of notice
is otherwise prescribed by law, stating the place, date and hour of the meeting,
and, in the case of a special meeting, indicating that it is being issued by or
at the direction of the person or persons calling the meeting and stating the
purpose or purposes for which it is called, shall be given, personally or by
mail, not less than ten (10) nor more than sixty (60) days before such meeting,
to each stockholder entitled to vote at such meeting, except that where the
matter to be acted on is a merger or consolidation of the Corporation or a sale,
lease or exchange of all or substantially all 

<PAGE>

of its assets, such notice shall be given not less than twenty (20) nor more
than sixty (60) days before such meeting. If mailed, such notice shall be deemed
given when deposited in the United States mail, postage prepaid, directed to
such stockholder at his address as it appears on the record of stockholders of
the Corporation. An affidavit of the Secretary or other person giving the notice
or of the transfer agent of the Corporation that notice has been given shall be
evidence of the facts stated therein.

      Notice of any meeting need not be given to any stockholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting. The attendance of any stockholder at a meeting, in person or by proxy,
shall constitute a waiver of notice by him except where the person is attending
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of stockholders, directors or committee of directors
need be specified in any written waiver of notice.

      Section 2.5. Adjourned Meeting and Notice Thereof. Any meeting of
stockholders may be adjourned to another time or place, and the Corporation may
transact at any adjourned meeting any business which might have been transacted
on the original date of the meeting. Notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting at which the
adjournment is taken, unless a new record date is fixed for the adjourned
meeting by the Board of Directors. If notice of the adjourned meeting is given,
such notice shall be given to each stockholder of record entitled to vote at the
adjourned meeting in the manner prescribed in Section 2.4.

      Section 2.6. Quorum. At any meeting of stockholders, except as otherwise
expressly required by law or the Certificate of Incorporation, the holders of a
majority of the shares entitled to vote at such meeting shall constitute a
quorum for the transaction of any business, provided that when a specified item
of business is required to be voted on by a class or series, voting as a class,
the holders of a majority of the shares of such class or series shall constitute
a quorum for the transaction of such specified item of business. In the absence
of a quorum, the stockholders present may adjourn such meeting. When a quorum is
once present to organize a meeting, the quorum is not broken by the subsequent
withdrawal of any stockholders.

      Section 2.7. Business At Annual Meeting. At an annual meeting of the
stockholders, only such business shall be conducted as shall have been properly
brought before the meeting. To be properly brought before an annual meeting,
business must be (a) specified in the notice of meeting (or any supplement
thereto) given by or at the direction of the Board of Directors, (b) otherwise
properly brought before the meeting by or at the direction of the Board of
Directors or (c) otherwise properly brought before the meeting by a stockholder.

      For business to be properly brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary. To be timely, a stockholder's notice must be received at the
principal executive offices of the Corporation no later than the date designated
for receipt of stockholders' proposals in a prior public disclosure made by the
Corporation. If there has been no such prior public disclosure, then to be
timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the Corporation not less than 60 days nor
more than 90 days prior to the annual meeting; 


                                       2
<PAGE>

provided, however, that in the event that less than 60 days' notice of the date
of the annual meeting is given to stockholders or prior public disclosure of the
date of the meeting is made, notice by the stockholder to be timely must be so
received not later than the close of business on the 10th day following the day
on which such notice of the date of the annual meeting was mailed or such public
disclosure was made. A stockholder's notice to the Secretary shall set forth as
to each matter the stockholder proposes to bring before the annual meeting (a) a
brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (b)
the name and address, as they appear on the Corporation's books, of the
stockholder proposing such business, (c) the class and number of shares of the
Corporation which are beneficially owned by the stockholder, (d) any material
interest of the stockholder in such business and (e) the same information
required by clauses (b), (c) and (d) above with respect to any other stockholder
that, to the knowledge of the stockholder proposing such business, supports such
proposal. Notwithstanding anything in these Bylaws to the contrary, no business
shall be conducted at an annual meeting except in accordance with the procedures
set forth in this Section 2.7. The Chairman shall, if the facts warrant,
determine that a matter of business was not properly brought before the meeting
in accordance with the provisions of this Section 2.7, and if the Chairman
should so determine, he shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

      Section 2.8. Voting. Every stockholder of record shall be entitled, at
every meeting of stockholders, to one (1) vote for every share standing in his
name on the record of stockholders of the Corporation unless otherwise provided
in the Certificate of Incorporation. Directors shall, unless otherwise required
by law or by the Certificate of Incorporation, be elected by a plurality of the
votes cast at a meeting of stockholders by the holders of shares entitled to
vote thereon. Whenever any corporate action, other than the election of
directors, is to be taken by vote of the stockholders, it shall, except as
otherwise required by law or by the Certificate of Incorporation, be authorized
by a majority of the votes cast at a meeting of stockholders by the holders of
shares entitled to vote thereon.

      Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent without a meeting may authorize another person or
persons to act for him by proxy. Every proxy must be signed by the stockholder
or his attorney-in-fact. No proxy shall be valid after the expiration of three
(3) years from the date thereof, unless otherwise provided in the proxy. Every
proxy shall be revocable at the pleasure of the stockholder executing it, except
as otherwise provided by law.

      The Board of Directors, in advance of any stockholders, meeting, may
appoint one (1) or more inspectors to act at the meeting or any adjournment
thereof. If inspectors are not so appointed, the person presiding at a
stockholders, meeting may, and on the request of any stockholder entitled to
vote thereat shall, appoint one (1) or more inspectors. In case any person
appointed fails to appear or act, the vacancy may be filled by appointment made
in advance of the meeting by the Board of Directors or at the meeting by the
person presiding thereat.

      Section 2.9. Voting Rights of Certain Shares. Neither treasury shares nor
shares held by another corporation, if a majority of the shares entitled to vote
in the election of directors of such other corporation is held by the
Corporation, shall be counted for quorum purposes or entitled to vote. Shares
held by an administrator, executor, guardian, conservator, committee, or other
fiduciary, except a trustee, may be voted by him, either in person or by proxy,


                                       3
<PAGE>

without transfer of such shares into his name. Shares held by a trustee may be
voted by him, either in person or by proxy, only after the shares have been
transferred into his name as trustee or into the name of his nominee. A
stockholder whose shares are pledged shall be entitled to vote such until the
shares have been transferred into the name of the pledgee, or a nominee of the
pledgee.

      Section 2.10. Action by Consent of Stockholders. Whenever a vote of
stockholders at a meeting thereof is required or permitted to be taken in
connection with any corporate action by any provision of statute or of the
Certificate of Incorporation or these By-Laws, the meeting, prior notice thereof
and vote of stockholders may be dispensed with if the holders of shares having
not less than the minimum number of votes that would have been necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted shall consent in writing to the taking of such
action. Where corporate action is taken in such manner by less than unanimous
written consent, prompt written notice of the taking of such action shall be
given to all stockholders who have not consented in writing thereto.

                        ARTICLE III - BOARD OF DIRECTORS

      Section 3.1. General Powers. The business of the Corporation shall be
managed by the Board of Directors. The Board of Directors may exercise all such
powers of the Corporation and have such authority and do all such lawful acts
and things as are permitted by law, the Certificate of Incorporation or these
Bylaws.

      Section 3.2. Number of Directors. The number of directors constituting the
entire Board of Directors shall be the number, not more than ten, as fixed from
time to time by a majority of the total number of directors which the
Corporation would have, prior to any increase or decrease, if there were no
vacancies, provided, however, that no decrease shall shorten the term of an
incumbent director. Until otherwise fixed by the directors, the number of
directors constituting the entire Board shall be five (5).

      Section 3.3. Election. Directors of the Corporation shall be elected to
hold office until the next annual meeting. At each annual meeting of
stockholders or at a special meeting in lieu of the annual meeting called for
such purpose, a new Board of Directors of the Corporation shall be elected.

      Section 3.4. Term. Each director shall hold office until the expiration of
the term for which he is elected and until his successor is duly elected and
qualified, except in the event of the earlier termination of his term of office
by reason of death, resignation, removal or other person.

      Section 3.5. Resignation and Removal. Any director may resign at any time
upon written notice to the Board of Directors, the Chief Executive Officer, the
President or the Secretary. The resignation of any director shall take effect
upon receipt of notice thereof or at such later time as shall be specified in
such notice, and unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

      Any director may be removed for cause by vote of the stockholders or the
Board of Directors. Any director may be removed without cause by vote of the
stockholders.


                                       4
<PAGE>

      Section 3.6. Vacancies. Newly created directorships resulting from an
increase in the number of directors and vacancies occurring in the Board of
Directors for any reason except the removal of directors without cause may be
filled by vote of a majority of the directors then in office, although less than
a quorum exists. Vacancies occurring in the Board of Directors by reason of the
removal of directors without cause may be filled only by vote of the
stockholders.

      A director elected to fill a vacancy shall be elected to hold office for
the unexpired term of his predecessor.

      Section 3.7. Nomination Of Directors. Nominations of persons for election
to the Board of Directors may be made by the Board of Directors, or by any
stockholder of the Corporation entitled to vote for the election of directors at
the annual meeting who complies with the notice procedures set forth in this
Section 3.7. Nominations by stockholders shall be made pursuant to timely notice
in writing to the Secretary. To be timely, a stockholder's notice shall be
received at the principal executive offices of the Corporation no later than the
date designated for receipt of stockholders' proposals in a prior public
disclosure made by the Corporation. If there has been no such prior public
disclosure, then to be timely, a stockholder's nomination must be delivered to
or mailed and received at the principal executive offices of the Corporation not
less than 60 days nor more than 90 days prior to the annual meeting; provided,
however, that in the event that less than 60 days' notice of the date of the
meeting is given to stockholders or prior public disclosure of the date of the
meeting is made, notice by the stockholder to be timely must be so received not
later than the close of business on the 10th day following the day on which such
notice of the date of the annual meeting was mailed or such public disclosure
was made. Such stockholder's notice shall set forth (a) as to each person whom
the stockholder proposes to nominate for election or re-election as a director,
(i) the name, age, business address and residence address of such person, (ii)
the principal occupation or employment of such person, (iii) the class and
number of shares of the Corporation which are beneficially owned by such person,
and (iv) any other information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (including without limitation such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); and (b) as to the stockholder giving notice (i) the name
and address, as they appear on the Corporation's books, of the stockholder
proposing such nomination, and (ii) the class and number of shares of the
Corporation which are beneficially owned by the stockholder. No person shall be
eligible for election as a director of the Corporation unless nominated in
accordance with the procedures set forth in this Section 3.7. The Chairman
shall, if the facts warrant, determine and declare to the annual meeting that a
nomination was not made in accordance with the provisions of this Section 3.7,
and if the Chairman should so determine, he shall so declare to the meeting and
the defective nomination shall be disregarded.

      Section 3.8. Quorum and Voting. Unless the Certificate of Incorporation
provides otherwise, at all meetings of the Board of Directors, a majority of the
entire Board of Directors shall constitute a quorum for the transaction of
business or of any specified item of business. A director interested in a
contract or transaction may be counted in determining the presence of a quorum
at a meeting of the Board of Directors which authorizes the contract or
transaction. In the absence of a quorum, a majority of the directors present may
adjourn the meeting until a quorum shall be present.


                                       5
<PAGE>

      The vote of the majority of the directors present at the time of a vote at
a meeting at which a quorum is present shall be the act of the Board of
Directors unless the Certificate of Incorporation shall require the vote of a
greater number.

      Section 3.9. Regulations. The Board of Directors may adopt such rules and
regulations for the conduct of the business and management of the Corporation,
not inconsistent with the law or the Certificate of Incorporation or these
By-Laws, as the Board of Directors may deem proper.

      The Board of Directors may hold its meetings at any place within or
without the State of Delaware as the Board of Directors may from time to time
determine.

      Section 3.10. Annual Meeting of Board of Directors. An annual meeting of
the Board of Directors shall be called and held for the purpose of organization,
election of officers and transaction of any other business. If such meeting is
held promptly after and at the place specified for the annual meeting of
stockholders, no notice of the annual meeting of the Board of Directors need be
given. Otherwise such annual meeting shall be held at such time (not more than
thirty (30) days after the annual meeting of stockholders) and place as may be
specified in a notice of the meeting.

      Section 3.11. Regular Meetings. Regular meetings of the Board of Directors
shall be held at the time and place as shall from time to time be determined by
the Board of Directors. After there has been such determination and notice
thereof has been given to each member of the Board of Directors, no further
notice shall be required for any such regular meeting. Except as otherwise
provided by law, any business may be transacted at any regular meeting.

      Section 3.12. Special Meetings. Special meetings of the Board of Directors
may, unless otherwise prescribed by law, be called from time to time by the
Chief Executive officer, and shall be called by the President or the Secretary
upon the written request of a majority of the Board of Directors then in office
directed to the President or the Secretary. Except as provided below, notice of
any special meeting of the Board of Directors, stating the time and place of
such special meeting, shall be given to each director.

      Section 3.13. Notice of Meeting; Waiver of Notice. Notice of any meeting
of the Board of Directors shall be deemed to be duly given to a director (i) if

capital stock of the Corporation shall be signed by, or in the name of the
Corporation by, (i) the Chairman of the Board, the Chief Executive Officer, the
President or a Vice President and by (ii) the Secretary, the Treasurer, an
Assistant Secretary or an Assistant Treasurer, and shall bear the corporate seal
of the Corporation or a printed or engraved facsimile thereof.

      If any such certificate is countersigned by a transfer agent or registered
by a register, other than the Corporation or its employee, any other signature
on the certificate may be a facsimile. In case any officer who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer before such certificate is issued, such certificate may be
issued by the Corporation with the same effect as if such signer were such
officer at the date of issue.

      Section 5.3. Stock Ledger. A record of all certificates for capital stock
issued by the Corporation shall be kept by the Secretary or any other officer,
employee or agent designated by the Board of Directors. Such record shall show
the name and address of each stockholder, the number and class of shares held by

of certificates which have been canceled, the dates of cancellation thereof.

      The Corporation shall be entitled to treat the holder of record of shares
of capital stock as shown on the stock ledger as the owner thereof and as the
person entitled to receive dividends thereon, to vote such shares, to receive
notice of meetings, and for all other purposes. Prior to due presentment for
registration of transfer of any certificate for shares of capital stock of the
Corporation, the Corporation shall not be bound to recognize any equitable or
other claim to or interest in any share of capital stock represented by such
certificate on the part of any other person whether or not the Corporation shall
have express or other notice thereof.

      Section 5.4. Regulations Relating to Transfer. The Board of Directors may
make such rules and regulations as it may deem expedient, not inconsistent with
law, the Certificate of Incorporation or these By-Laws, concerning issuance,
transfer and registration of certificates for shares of capital stock of the
Corporation. The Board of Directors may appoint, or authorize any principal
officer to appoint, one (1) or more transfer clerks or one (1) or more 


                                       10
<PAGE>

transfer agents and one (1) or more registers and may require all certificates
for capital stock to bear the signature or signatures of any of them.

      Section 5.5. Transfers. Transfers of capital stock shall be made on the
books of the Corporation only upon delivery to the Corporation or its transfer
agent of (i) a written direction of the registered holder named in the
certificate or such holder's attorney lawfully constituted in writing, (ii) the
certificate for the shares of capital stock being transferred, and (iii) a
written assignment of the shares of capital stock evidenced thereby.

      Section 5.6. Cancellation. Each certificate for capital stock surrendered
to the Corporation for exchange or transfer shall be canceled and no new
certificate or certificates shall be issued in exchange for any existing
certificate (other than pursuant to Section 5.7) until such existing certificate
shall have been canceled.

      Section 5.7. Lost, Destroyed, Stolen and Mutilated Certificates. In the
event that any certificate for shares of capital stock of the Corporation shall
be mutilated, the Corporation shall issue a new certificate in place of such
mutilated certificate. In case any such certificate shall be lost, stolen or
destroyed, the Corporation may, in the discretion of the Board of Directors or a
committee designated thereby with power so to act, issue a new certificate for
capital stock in the place of any such lost, stolen or destroyed certificate.
The applicant for any substituted certificate or certificates shall surrender
any mutilated certificate or, in the case of any lost, stolen or destroyed
certificate, furnish satisfactory proof of such loss, theft or destruction of
such certificate and of the ownership thereof. The Board of Directors or such
committee may, in its discretion, require the owner of a lost, stolen or
destroyed certificate, or his representatives, to furnish to the Corporation a
bond with an acceptable surety or sureties and in such sum as will be sufficient
to indemnify the Corporation against any claim that may be made against it on
account of the lost, stolen or destroyed certificate or the issuance of such new
certificate. A new certificate may be issued without requiring a bond when, in
the judgment of the Board of Directors, it is proper to do so.

      Section 5.8. Fixing of Record Date. (a) The Board of Directors may fix, in
advance, a record date, which shall not be more than sixty (60), nor less than
ten (10), days before the date of any meeting of stockholders, nor more than
sixty (60) days prior to any other action, for the purpose of determining
stockholders entitled to notice of or to vote at such meeting of stockholders or
any adjournment thereof, or to express consent or dissent to corporate action in
writing without a meeting, or to receive payment of any dividend or allotment of
any rights, or for the purpose of any other action, except that where the matter
to be acted on is a merger or consolidation of the Corporation or a sale, lease
or exchange of all or substantially all of its assets, such date shall be not
less than twenty nor more than sixty days prior to such meeting.

      (b) If no record date is fixed by the Board of Directors:

            (i) The record date for determining stockholders entitled to notice
of or to vote at a meeting of stockholders shall be at the close of business on
the next day preceding the day on which notice is given, or if no notice is
given, the day on which the meeting is held;

            (ii) The record date for determining stockholders for any purpose
other than that specified in subparagraph (i) shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto.


                                       11
<PAGE>

      (c) A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting,
provided that the Board of Directors may fix a new record date for the adjourned
meeting.

                          ARTICLE VI - INDEMNIFICATION

      Section 6.1. Indemnification. The Corporation shall indemnify any person
made, or threatened to be made, a party to an action or proceeding (including
one by or in the right of the Corporation to procure a judgment in its favor),
whether civil or criminal, including, but not limited to, an action by or in the
right of any other corporation of any type or kind, domestic or foreign, or any
partnership, joint venture, trust, employee benefit plan or other enterprise,
which any director or officer of the Corporation served in any capacity at the
request of the Corporation, by reason of the fact that he, his testator or
intestate, was a director or officer of the Corporation, or served such other
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise in any capacity, against judgments, fines, amounts paid in settlement
and reasonable expenses, including, but not limited to, attorneys' fees incurred
as a result of such action or proceeding, or any appeal therein, provided that
no indemnification shall be made to or on behalf of any director or officer of
the Corporation if a judgment or other final adjudication adverse to the
director or officer establishes that his acts were committed in bad faith or
were the result of active and deliberate dishonesty and were material to the
cause of action so adjudicated, or that he personally gained in fact a financial
profit or other advantage to which he was not legally entitled.

      The Corporation shall he deemed to have requested a person to serve an
employee benefit plan where the performance by such person of his duties to the
Corporation also imposes duties on, or otherwise involves services by, such
person to the plan or participants or beneficiaries of the plan; excise taxes
assessed on a person with respect to an employee benefit plan pursuant to
applicable law shall be considered fines.

      Expenses incurred in connection with a civil or criminal action or
proceeding may be paid by the Corporation in advance of the final disposition of
any such action or proceeding upon receipt of an undertaking by or on behalf of
the director or officer to repay the expenses so advanced, if the director or
officer is ultimately found not to be entitled to indemnification, and where the
director or officer is ultimately found to be entitled to some indemnification,
to the extent the expenses so advanced exceed the indemnification to which the
director or officer ultimately is found to be entitled.

      Notwithstanding the failure of the Corporation to provide indemnification,
and despite any contrary resolution of the Corporation's Board of Directors or
of the Corporation's stockholders in any specific case arising under the
Delaware General Corporation Law, indemnification shall be awarded by a court to
the maximum extent permitted under these By-laws. Application therefor may be
made, in every case, either:

            (i) In. the civil action or proceeding in which the expenses were
incurred or other amounts were paid, or

            (ii) To a court in a separate proceeding, in which case the
application shall set forth the disposition of any previous application made to
any court for the same or similar relief and also reasonable cause for the
failure to make application for such relief in the action or proceeding in which
the expenses were incurred or other amounts were paid.


                                       12
<PAGE>

      (a) The application shall be made in such manner and form as may be
required by the applicable rules of court or, in the absence thereof, by
direction of a court to which it is made. Such application shall be upon notice
to the Corporation. The court may also direct that notice be given at the
expense of the Corporation to the Corporation's stockholders and such other
persons as it may designate in such manner as it may require.

      (b) Where indemnification is sought by judicial action, the court may
allow a person such reasonable expenses, including attorneys' fees, during the
pendency of the litigation as are necessary in connection with his defense
therein.

      All expenses incurred defending a civil or criminal action or proceeding
which are allowed by a court under paragraph (b) above, shall be repaid in case
the director or officer receiving such allowance is ultimately found not to be
entitled to indemnification, and where the director or officer is ultimately
found to be entitled to some indemnification, to the extent the expenses so
allowed by the court exceed the indemnification to which the director or officer
ultimately is found to be entitled.

      Any indemnification by the Corporation pursuant hereto shall only be made
in the manner and to the extent authorized by applicable law, but shall be made
to the maximum extent permitted by applicable law, and such indemnification
shall not be deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.

      Section 6.2. Indemnification Insurance. To the extent permitted by law,
the Corporation shall have power to purchase and maintain insurance on behalf of
any person who is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such.

                     ARTICLE VII - MISCELLANEOUS PROVISIONS

      Section 7.1. Corporate Seal. The seal of the Corporation shall be circular
in form with the name of the Corporation in the circumference and the words and
figures "Corporate Seal - 1994, Delaware" in the center. The seal may be used by
causing it to be affixed or impressed, or a facsimile thereof may be reproduced
or otherwise used in such manner as the Board of Directors may determine.

      Section 7.2. Fiscal Year. The fiscal year of the Corporation shall end on
June 30 of each year, or such other twelve (12) consecutive months as the Board
of Directors may designate.

      Section 7.3. Execution of Instruments, Contracts, etc. All checks, drafts,
bill so exchange, notes or other obligations or orders for the payment of money
shall be signed in the name of the Corporation by such officer or officers or
person or persons, as the Board of Directors may from time to time designate.
Except as otherwise provided by law, the Board of Directors, any committee given
specific authority in the premises by the Board of Directors, or any committee
given authority to exercise generally the powers of the Board of Directors,
during the intervals between meetings of the Board of Directors, may authorize
any officer, employee or agent, in the name of and on behalf of the Corporation,
to enter into or execute and deliver deeds, 


                                       13
<PAGE>

bonds, mortgages, contracts and other obligations or instruments, and such
authority may be general or confined to specific instances.

      All applications, written instruments and papers required by any
department of the United States Government or by any state, county, municipal or
other governmental authority, may be executed in the name of the Corporation by
any principal officer or subordinate officer of the Corporation, or, to the
extent designated for such purpose from time to time by the Board of Directors,
by an employee or agent of the Corporation. Such designation may contain the
powers to substitute, in the discretion of the person named, one (1) or more
other persons.

                            ARTICLE VIII - AMENDMENTS

      Section 8.1. By Stockholders. These By-Laws may be amended or repealed, or
new By-Laws may be adopted, at any meeting of stockholders.

                                                                    Exhibit 10.1
                          REGISTRATION RIGHTS AGREEMENT

     This AGREEMENT is made as of February ___, 1997, by and among WORLDCOMM
     SYSTEMS INC, a Delaware corporation (hereinafter referred to as the
     "Company"), and those persons listed on Exhibit A attached hereto.

                                    RECITALS

Each of the Holders (as defined below) is the owner of shares of (i) the
Company's Class A Preferred Stock, par value $.01 per share, (ii) the Company's
Class B Preferred Stock, par value $.01 per share or (iii) the Company's Common
Stock, par value $.01 per share. Upon the closing of the Company's initial
public offering of its Common Stock, (i) the shares of such Preferred Stock held
by holders thereof will be automatically converted into shares of the Company's
Common Stock, par value $.001 per share pursuant to the terms of the
certificates of designation with respect to such Preferred Stock and to an
amendment and restatement of the Company's certificate of incorporation which is
being effected as of the effective date of the registration statement for such
public offering, and (iii) the shares of Common Stock, par value $.01 per share
held by Holders will be converted into shares of Common Stock, par value $.001
per share by the amendment and restatement referred to above. The shares of
Common Stock which will be held by the Holders following such transactions are
referred to in this Agreement as the "Shares." 

Each of the Holders is also a party to one or more stockholders' agreements or
registration rights agreements pursuant to which such Holder has been granted
certain rights with respect to the Shares. In connection with the Company's
initial public offering of its Common Stock, the underwriter has required each
Holder to enter into an agreement pursuant to which such Holder is agreeing that
he will not sell or otherwise dispose of any of the Shares for periods ranging
from 6 to 12 months from the effective date of the registration statement for
such offering. The stockholders' agreements referred to above will terminate
upon the effectiveness of such offering. The parties deem it to be in their best
interests, and in the best interests of the Company that the registration rights
of the Holders with respect to the Shares be set forth clearly in a separate
agreement which will survive the initial public offering, and that such
registration rights be identical for each Holder.

The parties therefore agree as follows.

1.   Registration Rights.

(a)  Definitions. For purposes of this Section 1:

          (i) The term "Act" means the Securities Act of 1933, as amended, or
any other statute in effect from time to time corresponding to such act.

          (ii) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement.

          (iii) The term "Registrable Securities" means (i) the Shares, (ii) any
securities of the Company issued as a dividend or other distribution with
respect to, or in exchange or in replacement of, the Shares and (iii) shares of
Common Stock the holders of which are entitled to registration rights pursuant
to other agreements of like tenor with the Company. Registrable Securities, if
transferred pursuant to an exemption from registration under the Act, will
remain Registrable Securities.

          (iv) The term "Holder" means (i) any stockholder holding Registrable
Securities originally acquired by such person, and (ii) any other person holding
Registrable Securities to whom these registration rights have been transferred.

          (v) The term "Initial Public Offering" means the first underwritten
public offering of the Company's securities amounting to not less than
$3,000,000.

(b)  Demand Registration.

          (i) Request for Registration. If, at any time after the Initial Public
Offering, the Company shall receive a written request (specifying that it is
being made pursuant to this Section 1(b)) from the Holders holding more than
twenty-five percent (25%) of the Registrable Securities held by all Holders at
that time outstanding that the Company file a registration statement or similar
document under the Act, covering the registration of not less than twenty-five
percent 25% of the Registrable Securities held by all the Holders, the expected
aggregate price to the public of which exceeds $3,000,000, net of underwriting
discounts and commissions, then the Company shall promptly notify all other
Holders of such request and shall use its best efforts to cause all Registrable
Securities that Holders have requested be so registered to be registered under
the Act.

          (ii) Right to Defer Registration. Notwithstanding the foregoing,


<PAGE>

               (A) the Company shall not be obligated to effect a registration
pursuant to this Section 1(b) during the period starting with the effective date
of the Initial Public Offering and extending for a period of twelve months
thereafter, and

               (B) the Company shall not be obligated to effect a registration
pursuant to this Section 1(b) during the period starting with the date sixty
(60) days prior to the Company's estimated date of filing of, and ending on a
date four (4) months following the effective date of, a registration statement
pertaining to an underwritten public offering of securities for the account of
the Company, provided that (x) the Company is actively employing in good faith,
all reasonable efforts to cause such registration statement to become effective
and that the Company's estimate of the date of filing of such registration
statement is made in good faith, and (y) the Company shall furnish to the
Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors it would be seriously detrimental
to the Company or its stockholders for a registration statement to be filed
prior to a date certain in the near future. If postponed, the Company's
obligation to use its best efforts to file a registration statement shall be
deferred for a period not to exceed the earlier of six (6) months after the
effective date of the registration statement or nine (9) months from the
estimated filing date of the registration statement

          (iii) Limit on Demand Registrations. The Company shall be obligated to
effect only one registration pursuant to this Section 1(b) initiated by Holders.
Further, each Holder shall be ineligible to request registration of any of his
Shares which may be sold without registration and without limitation as to
amount pursuant to Rule 144 or any successor or similar regulation or statute.
Any request for registration under this Section 1(b) must be for an underwritten
public offering to be managed by an underwriter or underwriters of recognized
national standing reasonably acceptable to the Company. 

(c) Piggy-back Registration. Subject to Sections 1(g) and 1(h) if at any time or
from time to time the Company proposes to register any of its equity securities
under the Act in connection with a primary or secondary public offering of such
securities solely for cash on a form that would also permit the registration of
the Registrable Securities, the Company shall, each such time, promptly give
each Holder written notice of such determination. Upon the written request of
any Holder given within twenty (20) days after mailing of any such notice by the
Company, the Company shall use its best efforts to cause to be registered under
the Act all of the common stock of the Company that each such Holder has
requested be registered.

(d) Obligations of the Company. Whenever required under Sections 1(b), or 1(c)
to use its best efforts to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

          (i) Prepare and file with the Securities and Exchange Commission
("SEC") a registration statement with respect to such Registrable Securities and
use its best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a
so-called "shelf registration"), the Company shall in no event be obligated to
cause any such registration to remain effective for more than ninety (90) days.

          (ii) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (iii) Furnish to the Holders and deliver as directed such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by them

          (iv) Use its best efforts to take such steps as may reasonably be
required to permits the sale the securities covered by such registration
statement under such other securities or Blue Sky laws of such jurisdictions as
shall be reasonably appropriate for the distribution of the securities covered
by the registration statement, provided that the Company shall not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions, and further provided that (anything in this Agreement to the
contrary notwithstanding with respect to the bearing of expenses) if any
jurisdiction in which the securities shall be qualified shall require that
expenses incurred in connection with the qualification of the securities in that
jurisdiction be borne by selling Stockholders, then such expenses shall be
payable by selling Stockholders pro rata, to the extent required by such
jurisdiction.

(e) Furnish Information. It shall be a condition precedent to the obligations of
the Company to take any action pursuant to Section 1 that the Holders shall
furnish to the Company such information regarding them, the


                                       2
<PAGE>

Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company. 

(f) Expenses of Demand Registration. All expenses incurred in connection with a
registration pursuant to Section 1(b) (excluding underwriters' discounts and
commissions), including without limitation all registration and qualification
fees, printers' and accounting fees, fees and disbursements of counsel for the
Company, and the reasonable fees and disbursements of one counsel for the
selling Holders shall be borne by the Company, provided, however, that the
Company shall not be required to pay for any of any registration proceeding
begun pursuant to Section 1(b) if the registration request is subsequently
withdrawn, unless the initiating Holders agree to forfeit their right to the
demand registration pursuant to Section 1(b); and provided further that the
initiating Holders may withdraw a request if the audited financial statements of
the Company materially and adversely differ from the information known to the
Holders at the time of their request, in which event the Holders shall not be
required to pay any of the expenses and shall retain the right to require the
Company to register Registrable Securities pursuant to Section 1(b).

(g) Piggy-back Registration Expenses. In the case of any registration effected
pursuant to Section 1(c), the Company shall bear all registration and state
filing fees and (excluding underwriters' discounts and commissions), including
any additional costs and disbursements of counsel for the Company that result
from the inclusion of securities held by the Holders in such registration. Each
selling Holder shall bear the fees and costs of its own counsel in connection
with any registration effected pursuant to Section 1(c).

(h) Underwriting Requirements. In connection with any offering involving an
underwriting of shares being issued by the Company, the Company shall not be
required to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it. If the total amount of
Registrable Securities that all Holders request to be included in an offering
pursuant to Sections 1(b) and 1(c) above exceeds the amount of securities that
the underwriters reasonably believe compatible with the success of the offering,
the Company shall only be required to include in the offering such number of
shares as the underwriters believe are compatible with the success of the
offering (the securities so included to be apportioned pro rata among the
selling Holders according to the total amount of Common Stock held by the
selling Holders as if all options and warrants held by them had been exercised,
or in such other proportions as shall mutually be agreed to by such selling
Holders). In the event a pro rata apportionment is required for purposes of a
registration pursuant to Section 1(c), securities shall be included in the
offering in the following priority and the pro rata apportionment shall occur in
the class after the last class which can be included in the offering without
apportionment: (1) all securities being offered by the Company or for its own
account; (2) Registrable Securities of Holders; and (3) Common Stock of
executive officers of the Company.

(i) Delay of Registration. No Holder shall have any right to take any action to
restrain, enjoin, or otherwise delay any registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Section 1.

(j) Indemnification and Contribution, Subject to Section l(g) in the event any
Registrable Securities are included in a registration statement under Section 1:

          (i) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934 (the "1934 Act") against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Act, the 1934 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based on any
untrue or alleged untrue statement of any material fact contained in such
registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein not
misleading, or arise out of any violation by the Company of any rule or
regulation promulgated under the Act or the 1934 Act applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration; and will reimburse each such Holder, such underwriter, or
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 1(j)(i) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld) nor shall the Company be liable in 


                                       3
<PAGE>

any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in connection with such
registration statement, preliminary prospectus, final prospectus, or amendments
or supplements thereto, in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
any such Holder, underwriter or controlling person.

          (ii) To the extent permitted by law, each Holder requesting or joining
in a registration will severally indemnify and hold harmless the Company, each
of its directors, each of its officers who have signed the registration
statement, each person, if any, who controls the Company within the meaning of
the Act or the 1934 Act, and each agent and any underwriter for the Company
(within the meaning of the Act or the 1934 Act) against any losses, claims,
damages or liabilities, joint or several, to which the Company or any such
director, officer, controlling person, agent or underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such registration statement, preliminary or final prospectus, or amendments
or supplements thereto, in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, agent or underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action, provided, however, that the
indemnity agreement contained in this Section 1(j)(ii) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of such Holder (which consent
shall not be unreasonably withheld).

          (iii) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this Section, notify the indemnifying party in writing of the commencement
thereof and (unless the interest of the indemnifying party conflicts with that
of the indemnified party) the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties. The failure to notify
an indemnifying party promptly of the commencement of any such action, if
prejudicial to his ability to defend such action, shall relieve such
indemnifying party, to the extent that he is prejudiced thereby, of any
liability to the indemnified party under this Section, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this Section

          (iv) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any Holder exercising
rights under this Agreement, or any controlling person of any such Holder, makes
a claim for indemnification pursuant to this Section 1(j) but it is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 1(j) provides for indemnification in
such case, or (ii) contribution under the Act may be required on the part of any
such selling Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 1(j); then, and in each such
case, the Company and such Holder will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that such Holder is responsible for the
portion represented by the percentage that the public offering price of its
Registrable Securities offered by the registration statement bears to the public
offering price of all securities offered by such registration statement, and the
Company is responsible for the remaining portion; provided, however, that, in
any such case, (A) no such Holder will be required to contribute any amount in
excess of the public offering price of all such Registrable Securities offered
by it pursuant to such registration statement; and (B) no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 1(f) of
the Act) will be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation.

2. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the


                                       4
<PAGE>

benefits of Rule 144 promulgated under the Act and any other rule or regulation
of the SEC that may at any time permit a Holder to sell securities of the
Company to the public without registration, the Company agrees to use its best
efforts to:

and defined in Rule 144, at all times subsequent to ninety (90) days after the
effective date of the first registration statement covering an underwritten
public offering filed by the Company;

(b) file with the SEC in a timely manner all reports and other documents
required of the Company under the 1934 Act, and

(c) furnish to any Holder so long as such Holder owns any of the Registrable
Securities forthwith upon request a written statement by the Company that it has
complied with the reporting requirements of Rule 144 (at any time after ninety
(90) days after the effective date of said first registration statement filed by
the Company), and of the Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), a copy of the most recent annual or
quarterly report of the Company, and such other reports and documents so filed
by the Company as may be reasonably requested in availing any Holder of any rule
or regulation of the SEC permitting the selling of any such securities without
registration.

3. Lockup Agreement. The Holders shall, in connection with any registration of
the Company's Common Stock for sale to the general public, upon the request of
the Company or the underwriters managing any underwritten offering of the
Company's securities, not sell, make short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Registrable Securities (other than
those included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred eighty (180) days) from the effective date of such
registration as the Company or the underwriters may specify; provided, however,
that the Company may not discriminate among the Holders with respect to any
lockup arrangements pursuant to this Section 3.

4. Certain Limitations in Connection with future Grants of Registration Rights.
From and after the date of this Agreement, the Company shall not enter into any
agreement with any holder or prospective holder of any securities of the Company
providing for the granting to such holder of registration rights unless: (a)
such agreement includes the equivalent of Section 3 as a term; and (b) such
registration rights, if more favorable than those granted herein, are extended
to the Holders or their transferees permitted under Section 5

5. Transfer of Registration Rights. The registration rights of a Holder under
Sections 1(b) and 1(c) may be transferred to a transferee who acquires at least
20% of the Registrable Securities originally issued to the Holder, or to a
partner or affiliated partnership of such Holder without restriction as to
minimum transfer amount. The Company shall be given written notice by the Holder
at the time of such transfer stating the name and address of the transferee and
identifying the securities with respect to which the rights under Section 1 are
being assigned.

6. Notices. Any notice required or permitted to be given pursuant to this
Agreement shall be in writing and shall be deemed to have been properly given
when delivered by hand or mailed by registered or certified mail, return receipt
requested, with postage prepaid, to the party or parties to whom such notice is
intended to be given at the address of such party first above written or such
other address as such party may designate by notice given hereunder

7. Miscellaneous.

any provision or provisions of this Agreement is found to be void or
unenforceable, the remaining provisions of this Agreement shall remain binding

Securities that Holders have requested be so registered to be registered under
the Act.

          (ii) Right to Defer Registration. Notwithstanding the foregoing,

               (A) the Company shall not be obligated to effect a registration

pertaining to an underwritten public offering of securities for the account of

time or from time to time the Company proposes to register any of its equity
securities under the Act in connection with a primary or secondary public
offering of such securities solely for cash on a form that would also permit the
registration of the Registrable Securities, the Company shall, each such time,
promptly give each Holder written notice of such determination. Upon the written
request of any Holder given within twenty (20) days after mailing of any such

Holder has requested be registered.

     (d) Obligations of the Company. Whenever required under Sections 1(b), or
1(c) to use its best efforts to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

          (i) Prepare and file with the Securities and Exchange Commission
("SEC") a registration statement with respect to such Registrable Securities and
use its best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a
so-called "shelf registration"), the Company shall in no event be obligated to
cause any such registration to remain effective for more than ninety (90) days.

          (ii) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the

          (iii) Furnish to the Holders and deliver as directed such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned

thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions, and further provided that (anything
in this Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling Stockholders, then such
expenses shall be payable by selling Stockholders pro rata, to the extent
required by such jurisdiction.

     (e) Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Section 1 that the
Holders shall furnish to the Company such information regarding them, the

such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.

     (f) Expenses of Demand Registration. All expenses incurred in connection
with a registration pursuant to Section 1(b) (excluding underwriters' discounts
and commissions), including without limitation all registration and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company, and the reasonable fees and disbursements of one
counsel for the selling Holders shall be borne by the Company, provided,
however, that the Company shall not be required to pay for any of any
registration proceeding begun pursuant to Section 1(b) if the registration
request is subsequently withdrawn, unless the initiating Holders agree to
forfeit their right to the demand registration pursuant to Section 1(b); and
provided further that the initiating Holders may withdraw a request if the
audited financial statements of the Company materially and adversely differ from
the information known to the Holders at the time of their request, in which
event the Holders shall not be required to pay any of the expenses and shall
retain the right to require the Company to register Registrable Securities
pursuant to Section 1(b).

     (g) Piggy-back Registration Expenses. In the case of any registration
effected pursuant to Section 1(c), the Company shall bear all registration and

<PAGE>

     (h) Underwriting Requirements. In connection with any offering involving an
underwriting of shares being issued by the Company, the Company shall not be
required to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it. If the total amount of
Registrable Securities that all Holders request to be included in an offering
pursuant to Sections 1(b) and 1(c) above exceeds the amount of securities that
the underwriters reasonably believe compatible with the success of the offering,
the Company shall only be required to include in the offering such number of
shares as the underwriters believe are compatible with the success of the
offering (the securities so included to be apportioned pro rata among the
selling Holders according to the total amount of Common Stock held by the
selling Holders as if all options and warrants held by them had been exercised,
or in such other proportions as shall mutually be agreed to by such selling
Holders). In the event a pro rata apportionment is required for purposes of a
registration pursuant to Section 1(c), securities shall be included in the
offering in the following priority and the pro rata apportionment shall occur in
the class after the last class which can be included in the offering without
apportionment: (1) all securities being offered by the Company or for its own
account; (2) Registrable Securities of Holders; and (3) Common Stock of
executive officers of the Company.

     (i) Delay of Registration. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

     (j) Indemnification and Contribution, Subject to Section l(g) in the event
any Registrable Securities are included in a registration statement under
Section 1:

          (i) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934 (the "1934 Act") against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Act, the 1934 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based on any
untrue or alleged untrue statement of any material fact contained in such
registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein not
misleading, or arise out of any violation by the Company of any rule or
regulation promulgated under the Act or the 1934 Act applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration; and will reimburse each such Holder, such underwriter, or
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 1(j)(i) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld) nor shall the Company be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus, or amendments or supplements thereto,
in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by any such Holder, underwriter or
controlling person

          (ii) To the extent permitted by law, each Holder requesting or joining
in a registration will severally indemnify and hold harmless the Company, each
of its directors, each of its officers who have signed the registration
statement, each person, if any, who controls the Company within the meaning of
the Act or the 1934 Act, and each agent and any underwriter for the Company
(within the meaning of the Act or the 1934 Act) against any losses, claims,
damages or liabilities, joint or several, to which the Company or any such
director, officer, controlling person, agent or underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such registration statement, preliminary or 
<PAGE>

final prospectus, or amendments or supplements thereto, in reliance upon and in
conformity with written information furnished by such Holder expressly for use
in connection with such registration; and each such Holder will reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, agent or underwriter in connection with
investigating or defending any such loss, claim, damage, liability or action,
provided, however, that the indemnity agreement contained in this Section
1(j)(ii) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of such Holder (which consent shall not be unreasonably withheld).

          (iii) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this Section, notify the indemnifying party in writing of the commencement
thereof and (unless the interest of the indemnifying party conflicts with that
of the indemnified party) the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties. The failure to notify
an indemnifying party promptly of the commencement of any such action, if
prejudicial to his ability to defend such action, shall relieve such
indemnifying party, to the extent that he is prejudiced thereby, of any
liability to the indemnified party under this Section, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this Section

          (iv) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any Holder exercising
rights under this Agreement, or any controlling person of any such Holder, makes
a claim for indemnification pursuant to this Section 1(j) but it is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 1(j) provides for indemnification in
such case, or (ii) contribution under the Act may be required on the part of any
such selling Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 1(j); then, and in each such
case, the Company and such Holder will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that such Holder is responsible for the
portion represented by the percentage that the public offering price of its
Registrable Securities offered by the registration statement bears to the public
offering price of all securities offered by such registration statement, and the
Company is responsible for the remaining portion; provided, however. that, in
any such case, (A) no such Holder will be required to contribute any amount in
excess of the public offering price of all such Registrable Securities offered
by it pursuant to such registration statement; and (B) no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 1(f) of
the Act) will be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation. 

2. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to use its best efforts to:

     (a) make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Company;

     (b) file with the SEC in a timely manner all reports and other documents
required of the Company under the 1934 Act, and

     (c) furnish to any Holder so long as such Holder owns any of the
Registrable Securities forthwith upon request a written statement by the Company
that it has complied with the reporting requirements of Rule 144 (at any time
after ninety (90) days after the effective date of said first registration
statement filed by the Company), and of the Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed by the Company as may be reasonably requested in availing any
Holder of any rule or regulation of the SEC permitting the selling of any such
securities without registration. 

3. Lockup Agreement. The Holders shall, in connection with any registration of
the Company's Common Stock for sale to the general public, upon the request of
the Company or the underwriters managing any 
<PAGE>

underwritten offering of the Company's securities, not sell, make short sale of,
loan, grant any option for the purchase of, or otherwise dispose of any
Registrable Securities (other than those included in the registration) without
the prior written consent of the Company or such underwriters, as the case may
be, for such period of time (not to exceed one hundred twenty (120) days) from
the effective date of such registration as the Company or the underwriters may
specify; provided, however, that the Company may not discriminate among the
Holders with respect to any lockup arrangements pursuant to this Section 3.

4. Certain Limitations in Connection with future Grants of Registration Rights.
From and after the date of this Agreement, the Company shall not enter into any
agreement with any holder or prospective holder of any securities of the Company
providing for the granting to such holder of registration rights unless:

     (a) such agreement includes the equivalent of Section 3 as a term; and

     (b) such registration rights, if more favorable than those granted herein,
are extended to the Holders or their transferees permitted under Section 5

5. Transfer of Registration Rights. The registration rights of a Holder under
Sections 1(b) and 1(c) may be transferred to a transferee who acquires at least
20% of the Registrable Securities originally issued to the Holder, or to a
partner or affiliated partnership of such Holder without restriction as to
minimum transfer amount. The Company shall be given written notice by the Holder
at the time of such transfer stating the name and address of the transferee and
identifying the securities with respect to which the rights under Section 1 are
being assigned.

6. Notices. Any notice required or permitted to be given pursuant to this
Agreement shall be in writing and shall be deemed to have been properly given
when delivered by hand or mailed by registered or certified mail, return receipt
requested, with postage prepaid, to the party or parties to whom such notice is
intended to be given at the address of such party first above written or such
other address as such party may designate by notice given hereunder

7. Miscellaneous.

     (a) This Agreement shall be governed by the laws of the State of New York.
If any provision or provisions of this Agreement is found to be void or
unenforceable, the remaining provisions of this Agreement shall remain binding
and in full force and effect

     (b) Wherever appropriate, the singular shall be deemed also to mean the
plural, and visa versa, and the male gender shall comprehend the female and
neuter. The captions in this Agreement are for convenience only, and shall not
affect the construction of the provisions hereof.

     (c) This Agreement may be terminated, waived or modified only by a written
agreement executed by the party against which enforcement of such termination,
waiver or modification is sought. This Agreement merges all prior understandings
of the parties with respect to the subject matter hereof:

     (d) This Agreement may be executed in several counterparts, each of which
shall constitute an original, but all counterparts shall constitute but one and
the same Agreement.

     (e) This Agreement shall be binding upon and shall inure to the benefit of
the parties and their respective heirs, executors, administrators, legal
representatives, successors and permitted assigns.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.

                          REGISTRATION RIGHTS AGREEMENT

          This AGREEMENT is made as of December 31, 1996, by and among WORLDCOMM
     SYSTEMS INC, a Delaware corporation (hereinafter referred to as the
     "Company"), and those persons listed on Exhibit A attached hereto.

                                    RECITALS

     Each of the Holders (as defined below) is the owner of shares of the
Company's Class B Preferred Stock, par value $.01 per share. The shares of such
Preferred Stock held by such Holders are referred to in this Agreement as the
"Shares." 

1.   Registration Rights.

     (a) Definitions. For purposes of this Section 1:

          (i) The term "Act" means the Securities Act of 1933, as amended, or
any other statute in effect from time to time corresponding to such act.

          (ii) The terms "register," "registered," and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Act and the declaration or ordering of effectiveness of such
registration statement.

          (iii) The term "Registrable Securities" means (i) the shares of Common
Stock issuable upon conversion of the Shares, (ii) any securities of the Company
issued as a dividend or other distribution with respect to, or in exchange or in
replacement of, Registrable Securities and (iii) shares of Common Stock the
holders of which are entitled to registration rights pursuant to other
agreements of like tenor with the Company. Registrable Securities, if
transferred pursuant to an exemption from registration under the Act, will
remain Registrable Securities.

          (iv) The term "Holder" means (i) any stockholder holding Registrable
Securities originally acquired by such person, and (ii) any other person holding
Registrable Securities to whom these registration rights have been transferred.

          (v) The term "Initial Public Offering" means the first underwritten
public offering of the Company's securities amounting to not less than
$3,000,000.

     (b) Rights to Include Shares in Initial Public Offering. Subject to
Sections 1(f) and 1(g) if at any time or from time to time the Company
determines to register its Common Stock under the Act in connection with an
initial public offering of such securities, the Company shall, each such time,
promptly give each Holder written notice of such determination. Upon the written
request made on behalf of the Holder in accordance with this Section 1(b), and
given within twenty (20) days after mailing of any such notice by the Company,
the Company shall use its best efforts to cause to be included in such
registration statement all of the Registrable Securities owned by such Holder
with respect to which registration has been so requested. A request for
registration in accordance which this Section 1(b) may be made only by Andrew B.
Krieger, as agent and attorney-in-fact for the Holders, and may not be made by
any Holder independently. Each Holder constitutes and appoints Andrew B. Krieger
as his agent and attorney-in-fact for the purpose of making such request, with
full power and authority to determine, subject to the following provisions of
this Section 1(b), (i) whether to make such request, and (ii) if such request is
made, and the number of shares of Holders to be included in such registration.
In determining whether to make such request, and the number of shares with
respect to which registration is to be requested, Mr. Krieger shall consider,
among other things, any adverse impact which the inclusion of Holders' shares
would have on the Company's ability to obtain financing. If required by the
underwriter in connection with such offering, each Holder shall agree to a
"lock-up" of his shares for such period as the underwriter may require. Each
Holder constitutes and appoints Andrew B. Krieger as his agent and
attorney-in-fact to execute and deliver on his behalf a "lock-up" agreement with
such underwriter in such form and upon such terms as Mr. Krieger may, in his
sole discretion, determine. Each Holder further acknowledges that Mr. Krieger is
a Director of the Company, and in that capacity has certain fiduciary
obligations to the Company and its stockholders, and nothing contained herein is
intended to require Mr. Krieger to take any action which he believes to be
inconsistent with such obligations.

     (c) Piggyback Registration. Subject to Sections 1(f) and 1(g), if at any
time or from time to time the Company proposes to register any of its equity
securities under the Act in connection with a primary or secondary public
offering of such securities solely for cash on a form that would also permit the
registration of the Registrable Securities, the Company shall, each such time,
promptly give each Holder written notice of such determination. Upon the written
request of any Holder given within twenty (20) days after mailing of any such
notice by the Company, the Company shall use its best efforts to cause to be
registered under the Act all of the Registrable 

<PAGE>

Securities that each such Holder has requested be registered. Notwithstanding
the foregoing, the Company shall not be obligated to include shares to be
offered by Holders in a registration statement in accordance with this Section
1(c) on more than two occasions.

     (d) Obligations of the Company. Whenever required under Section 1(b) or
1(c) to use its best efforts to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

          (i) Prepare and file with the Securities and Exchange Commission
("SEC") a registration statement with respect to such Registrable Securities and
use its best efforts to cause such registration statement to become and remain
effective; provided, however, that in connection with any proposed registration
intended to permit an offering of any securities from time to time (i.e., a
so-called "shelf registration"), the Company shall in no event be obligated to
cause any such registration to remain effective for more than ninety (90) days.

          (ii) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (iii) Furnish to the Holders and deliver as directed such numbers of
copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by them

          (iv) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably appropriate for the
distribution of the securities covered by the registration statement, provided
that the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions, and further provided that (anything
in this Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling Stockholders, then such
expenses shall be payable by selling Stockholders pro rata, to the extent
required by such jurisdiction.

     (e) Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Section 1 that the
Holders shall furnish to the Company such information regarding them, the
Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.

     (f) Registration Expenses. In the case of any registration effected
pursuant to Section 1(b) or 1(c), the Company shall bear all registration and
qualification fees and (excluding underwriters' discounts and commissions),
including any additional costs and disbursements of counsel for the Company that
result from the inclusion of securities held by the Holders in such
registration. Each selling Holder shall bear the fees and costs of its own
counsel in connection with any registration effected pursuant to such Sections

     (g) Underwriting Requirements. In connection with any offering involving an
underwriting of shares being issued by the Company, the Company shall not be
required to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it. If the total amount of
Registrable Securities that all Holders request to be included in an offering
pursuant to Section 1(c) above exceeds the amount of securities that the
underwriters reasonably believe compatible with the success of the offering, the
Company shall only be required to include in the offering such number of shares
as the underwriters believe are compatible with the success of the offering (the
securities so included to be apportioned pro rata among the selling Holders
according to the total amount of Common Stock held by the selling Holders as if
all options and warrants held by them had been exercised, or in such other
proportions as shall mutually be agreed to by such selling Holders). In the
event a pro rata apportionment is required for purposes of a registration
pursuant to Section 1(b), securities shall be included in the offering in the
following priority and the pro rata apportionment shall occur in the class after
the last class which can be included in the offering without apportionment: (1)
all securities being offered by the Company for its own account; (2) Registrable
Securities of Holders; and (3) Common Stock of executive officers of the
Company.

     (h) Delay of Registration. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 1.


                                       2

     (i) Indemnification and Contribution, Subject to Section 1(f) in the event
any Registrable Securities are included in a registration statement under
Section 1:

          (i) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder requesting or joining in a registration, any
underwriter (as defined in the Act) for it, and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the
Securities Exchange Act of 1934 (the "1934 Act") against any losses, claims,
damages or liabilities, joint or several, to which they may become subject under
the Act, the 1934 Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based on any
untrue or alleged untrue statement of any material fact contained in such
registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein, or necessary to make the statements therein not
misleading, or arise out of any violation by the Company of any rule or
regulation promulgated under the Act or the 1934 Act applicable to the Company
and relating to action or inaction required of the Company in connection with
any such registration; and will reimburse each such Holder, such underwriter, or
such controlling person for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 1(i)(i) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company (which consent shall not be unreasonably
withheld) nor shall the Company be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus, or amendments or supplements thereto,
in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by any such Holder, underwriter or
controlling person

          (ii) To the extent permitted by law, each Holder requesting or joining
in a registration will severally indemnify and hold harmless the Company, each
of its directors, each of its officers who have signed the registration
statement, each person, if any, who controls the Company within the meaning of
the Act or the 1934 Act, and each agent and any underwriter for the Company
(within the meaning of the Act or the 1934 Act) against any losses, claims,
damages or liabilities, joint or several, to which the Company or any such
director, officer, controlling person, agent or underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus, or any amendments or supplements thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such registration statement, preliminary or final prospectus, or amendments
or supplements thereto, in reliance upon and in conformity with written
information furnished by such Holder expressly for use in connection with such
registration; and each such Holder will reimburse any legal or other expenses
reasonably incurred by the Company or any such director, officer, controlling
person, agent or underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action, provided, however, that the
indemnity agreement contained in this Section 1(i)(ii) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of such Holder (which consent
shall not be unreasonably withheld).

          (iii) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this Section, notify the indemnifying party in writing of the commencement
thereof and (unless the interest of the indemnifying party conflicts with that
of the indemnified party) the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties. The failure to notify
an indemnifying party promptly of the commencement of any such action, if
prejudicial to his ability to defend such action, shall relieve such
indemnifying party, to the extent that he is prejudiced thereby, of any
liability to the indemnified party under this Section, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this Section


                                       3
<PAGE>

          (iv) In order to provide for just and equitable contribution to joint
liability under the Act in any case in which either (i) any Holder exercising
rights under this Agreement, or any controlling person of any such Holder, makes
a claim for indemnification pursuant to this Section 1(i) but it is judicially
determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last
right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 1(i) provides for indemnification in
such case, or (ii) contribution under the Act may be required on the part of any
such selling Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 1(i); then, and in each such
case, the Company and such Holder will contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (after contribution
from others) in such proportion so that such Holder is responsible for the
portion represented by the percentage that the public offering price of its
Registrable Securities offered by the registration statement bears to the public
offering price of all securities offered by such registration statement, and the
Company is responsible for the remaining portion; provided, however. that, in
any such case, (A) no such Holder will be required to contribute any amount in
excess of the public offering price of all such Registrable Securities offered
by it pursuant to such registration statement; and (B) no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 1(f) of
the Act) will be entitled to contribution from any person or entity who was not
guilty of such fraudulent misrepresentation. 

2. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to use its best efforts to:

     (a) make and keep public information available, as those terms are
understood and defined in Rule 144, at all times subsequent to ninety (90) days
after the effective date of the first registration statement covering an
underwritten public offering filed by the Company;

     (b) file with the SEC in a timely manner all reports and other documents
required of the Company under the 1934 Act, and

     (c) furnish to any Holder so long as such Holder owns any of the
Registrable Securities forthwith upon request a written statement by the Company
that it has complied with the reporting requirements of Rule 144 (at any time
after ninety (90) days after the effective date of said first registration
statement filed by the Company), and of the Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed by the Company as may be reasonably requested in availing any
Holder of any rule or regulation of the SEC permitting the selling of any such
securities without registration.

3. Lockup Agreement. The Holders shall, in connection with any registration of
the Company's Common Stock for sale to the general public, upon the request of
the Company or the underwriters managing any underwritten offering of the
Company's securities, not sell, make short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any Registrable Securities (other than
those included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred twenty (120) days) from the effective date of such
registration as the Company or the underwriters may specify; provided, however,

Worldcomm Systems Inc.
375 Oser Avenue
Hauppauge, NY  11788

                                                              November 9th, 1995

and Worldcomm Systems Inc. ("WSI") agrees to issue and sell to Thomson, 70,000
shares of common stock, par value $0.01 per share, of WSI ("Shares") for a total

check at a closing (the "Closing") to occur at WSI's offices at the address set
forth above no later than November 20th, 1995.

   2. General Rights and Obligations of Thomson. Thomson shall have all of the

was contemplated as, and shall be deemed for all purposes to be, the "corporate
investor" referred to in Sections 1.03(c), 2.05(a) and 2.05(b) of the Group "A"
Shareholders' Agreement, dated March 28th, 1995, among WSI and certain
shareholders of WSI, a copy of which (certified by the Secretary of WSI as true
and correct) is attached hereto as Annex 1 (the "Shareholders' Agreement"), and
in Section 7.3(b) of the form Subscription Agreement to the Private Placement,
executed and delivered by each of the investors in the Private Placement, a copy
of which (certified by the Secretary of WSI as true and correct) is attached
hereto as Annex 2 (the "Subscription Agreement") and that, without prejudice to
WSI's right otherwise to seek further equity financing as approved by its Board
of Directors, there shall be no further "corporate investors" within the meaning
of such sections of the Shareholders' Agreement or such section of the
Subscription Agreement. Pursuant to Section 7.3(b) of the Subscription
Agreement, WSI hereby deems all of the investors in the Private Placement to
have approved and consented to this Agreement.

   3. Condition to Closing. The obligation of Thomson to consummate the Closing
is subject to (a) the accuracy as of the closing of the representations and
warranties of WSI herein in all material respects, (b) the performance and
compliance as of the Closing by WSI in all material respects of its undertakings
and agreements herein and (c) the execution and delivery to Thomson, at or prior
to the Closing, by parties to the Shareholders' Agreement set forth in Annex 3
hereto (together with each such party's shareholdings) representing not less
than 59% of the outstanding share capital and voting rights of

                                                                  Execution Copy


WSI as of the Closing, of a consent in the form attached hereto as Annex 4.

   4. Special Rights of Thomson. WSI hereby agrees that Thomson shall have the
rights provided in Paragraph 2 and certain additional rights set out below in
respect of WSI and each of the shareholders set forth in Annex 3 who executes
and delivers the consent referred to in Paragraph 3. WSI hereby agrees as
follows:

      (a) Public Offering Preemptive Right. In the event WSI proposes to issue
securities through a public offering of securities for payment in cash, whether
by decision of the Board of Directors of WSI or a General Meeting of
Shareholders, WSI shall give Thomson prompt written notice of such proposal,
including information regarding (i) the number and class or series of the
securities proposed to be sold, and, if such securities will be of a new class,
the rights, preferences and restrictions applicable to such new class, (ii) the
price or price range at which WSI expects to offer such securities and (iii) the
proposed terms of payment and any other material terms and conditions of the
offering. WSI shall also give Thomson written notice of the public offering
price simultaneously with the final determination thereof. Thomson shall have a
preemptive right (with priority over any rights of any other shareholder) to
purchase up to 15% of the total number of securities offered in such public
offering (or such greater number of securities as the Board of Directors of WSI
may approve) at a price per security equal to the public offering price and on
the other terms and conditions of the public offering. In order to exercise its
preemptive right under this Paragraph 4(a), Thomson must notify WSI thereof in
writing not later than thirty (30) minutes after receipt by Thomson of written
notice of the final public offering price. Such notice shall state the number of
securities which Thomson desires to purchase and shall be deemed to be an
irrevocable commitment on the part of Thomson to purchase the number of
securities set forth therein for the public offering price and upon the other
terms and conditions of the public offering. Thomson agrees to consult,
regularly and on a timely basis, with WSI and the managing underwriter (if any)
of the public offering in connection with its exercise of its preemptive right
pursuant to this Paragraph 4(a).

      (b) Private Offering Preemptive Right.

      (i)   In the event WSI proposes to issue securities through a private
            offering of securities for payment in cash, whether by decision of
            the Board of Directors of WSI or a General Meeting of Shareholders,
            WSI shall give Thomson prompt written notice of such proposal (a
            "Private Offering Notice"), including information regarding (A) the
            number and class or series of the securities proposed to be sold
            (the "Offered Securities"), and, if such securities will be of a new
            class, the rights, preferences and restrictions applicable to


                                       2
<PAGE>

            such new class, (B) if known, the identity of any proposed third
            party acquiror or acquirors of the Offered Securities, (C) the price
            per security at which WSI proposes to sell the Offered Securities
            (the "Offer Price") and (D) the proposed terms of payment and any
            other material terms and conditions of the proposed sale. Subject to
            the provisions of Paragraph 4(b)(iv), Thomson shall have a
            preemptive right with WSI to purchase its Pro Rata Part (as
            hereinafter defined) of the Offered Securities at the Offer Price
            and on the other terms and conditions set forth in the Private
            Offering Notice. "Pro Rata Part" shall mean the proportion which the
            number of voting securities of WSI owned by Thomson bears to the
            number of voting securities of WSI owned by all shareholders
            (including Thomson) immediately prior to the date subscriptions are
            opened in such private offering. In order to exercise its preemptive
            right under this Paragraph 4(b)(i), Thomson must notify WSI thereof
            in writing not later than fifteen (15) days after receipt by Thomson
            of the Private Offering Notice. Such notice shall state the number
            of securities which Thomson desires to purchase and shall be deemed
            to be an irrevocable commitment on the part of Thomson to purchase
            the number of securities set forth therein for the Offering Price
            upon the other terms and conditions set forth in the Private
            Offering Notice.

      (ii)  To the extent the other shareholders have not elected, prior to the
            fifth day preceding the date subscriptions are opened in such
            private offering, to purchase, pursuant to their preemptive rights
            (if any) existing as of the date hereof, all of the Offered
            Securities as to which Thomson has not exercised its preemptive
            right under Paragraph 4(b)(i) (the "Remaining Securities"), WSI
            shall give Thomson written notice thereof (a "Notice of Remaining
            Securities"), not later than the forth day preceding the date
            subscriptions are opened in such private offering, including the
            number of Remaining Securities. Thomson shall have an additional
            preemptive right, subject to the provision of Paragraph 4(b)(iv), to
            purchase all or any portion of the Remaining Securities at the Offer
            Price and on the other terms and conditions set forth in the Private
            Offering Notice. In order to exercise its right under this Paragraph
            4(b)(ii), Thomson must notify WSI thereof in writing not later than
            three days after receipt by Thomson of the Notice of Remaining
            Securities. Such notice shall state the number of Remaining
            Securities which Thomson desires to purchase and shall be deemed to
            be an irrevocable commitment on the part of Thomson to purchase the
            number of securities set forth therein for the Offer Price and upon
            the other terms

<PAGE>

                                                                  Execution Copy


and conditions set forth in the Private Offering Notice.

      (iii) To the extent Thomson and the other shareholders do not elect to
            purchase all of the Offered Securities pursuant to their respective
            preemptive rights, WSI may sell the shares of Offered Securities as
            to which such preemptive rights have not been exercised within a
            period of six (6) months following the date the subscriptions are
            opened in such private offering, at a price per security not less
            than the Offer Price and on such other terms and conditions as are
            no more favorable to the purchasers than those specified in the
            Private Offering Notice. If any such sale of Offered Securities by
            WSI is not completed within such six-month period, the provisions of
            this Paragraph 4(b) shall again apply.

      (iv)  Thomson agrees not to exercise its preemptive rights under Paragraph
            4(b)(i) and 4(b)(ii) in the case of any private offering of
            securities by WSI exclusively to a single industrial entity as part
            of a Strategic Business Alliance (as hereinafter defined) with such
            entity. "Strategic Business Alliance" shall mean a strategic
            business alliance with an industrial entity where (A) the Board of
            Directors of WSI has been given a written report outlining in
            reasonable detail the business objectives and commercial advantages
            to be obtained by WSI and providing a business plan demonstrating
            the commercial advantages to WSI in connection with such strategic
            business alliance, (B) such strategic business alliance has been
            approved by a majority vote of the Board of Directors of WSI after
            full consideration of any strong and well reasoned objection thereto
            by any director on the Board of Directors or any shareholder owning
            at least 5% of the share capital of WSI and (C) the industrial
            entity with which such strategic business alliance is proposed is
            not a competitor of Thomson, as set out in Annex 5 hereto.

      (c) Board Seat. Subject to Paragraph 7(a), the Board of Directors of WSI
shall at all times include as a director such person as Thomson may from time to
time notify to WSI, provided (i) for the period from the Closing to the date of
the next Annual Shareholders Meeting of WSI (September 1996), the Thomson
nominee shall be appointed to the Board of Directors of WSI by action of the
Board of Directors and (ii) thereafter at each Annual Shareholders Meeting, the
Board of Directors of WSI shall nominate the nominee designated by Thomson and
shall recommend the election of such nominee to the shareholders of WSI.

      (d) Shares for Orders. Thomson shall receive Shares in consideration for
Orders in accordance with Paragraph 9(c) below.

                                                                  Execution Copy


      (e) Survival of Rights. Thomson's rights under Paragraphs 4, 5 and 9(c) of
this Agreement shall not be affected by the termination of the Shareholders'
Agreement.

   5. Assignment of Priority Right of First Refusal. Subject to Paragraph 7(a),
WSI hereby irrevocably assigns and transfers to Thomson, effective as of the
Closing, its priority right of first refusal under Sections 1.03(c) and
1.03(e)(i) of the Shareholders' Agreement. WSI represents and warrants that, as
a result of such assignment, Thomson shall have a right of first refusal (with
priority over the rights of first refusal of the other shareholders) to purchase
any Shares proposed to be transferred by any shareholder, at a price per Share
equal to the bona fide third party purchase price offered to such shareholder.
Thomson's rights under this Paragraph 5 shall not cover Shares which are
encumbered, sold or otherwise disposed of (a) to a shareholder of WSI by any
other shareholder of WSI with the prior written consent of the Board of
Directors of WSI pursuant to Section 1.03(a) of the Shareholders' Agreement, (b)
by an investor in the Private Placement who is not a party to the Shareholders'
Agreement, or (c) pursuant to Section 1.01(b) of the Shareholders' Agreement.

   6. Representations and Warranties of WSI. WSI hereby represents, warrants and
covenants to Thomson as follows:

      (a) the Shares to be purchased by Thomson pursuant to Paragraph 1 above
shall represent approximately 5.4%, but in no event less than 5%, of the
outstanding share capital and voting rights of WSI as of the Closing, and WSI
shall certify to Thomson, on or prior to the Closing, the exact percentage of
the outstanding share capital and voting rights of WSI represented by 70,000
Shares;

      (b) to WSI's best knowledge as of the Closing, there are no restrictions
under applicable law on (i) the ability of Thomson to exercise its right to
nominate a director to the Board of Directors of WSI as contemplated under
Paragraph 4(c) above and (ii) the ability of Thomson's nominee to the Board of
Directors of WSI to participate fully as a director in the management of WSI;
and

of the Board of Directors of WSI.

   7. Representations and Warranties of Thomson. Thomson hereby represents,
warrants and covenants to WSI, effective as of the Closing, as follows:

      (a) Thomson's rights under Paragraphs 4, 5, and 9(c) of this Agreement

other disposition(s), Thomson and its permitted transferees shall

<PAGE>

                                                                  Execution Copy


collectively own less than 5% of the outstanding share capital of WSI.

      (b) Thomson has been provided with or permitted access to all information
regarding WSI which it deems material to formulating an investment decision and
such information (assuming its accuracy and completeness) has been sufficient to
make an informed investment decision.

   8. Covenants of WSI. No later than three (3) days following the execution of
this Agreement by WSI, WSI shall furnish to Thomson complete copies of all of
the offering documents furnished or made available to other offerees in
connection with the Private Placement including, without limitation, the
offering memorandum and the Subscription Agreement (the "Offering Documents").
WSI shall use its good faith best efforts to fulfil or obtain the fulfilment of
the condition to Closing set forth in Paragraph 3 above.

   9. Business Cooperation. The parties intend for this Agreement to result in
short- and long-term business cooperation between them. Thomson further intends
to offer business opportunities to WSI after the Closing. In order to facilitate
the achievement of the foregoing objectives, the parties agree, effective as of
the Closing, as follows:

      (a) Thomson shall make a good faith effort to provide WSI with business
and marketing assistance in the field of satellite communications.

      (b) WSI shall make good faith effort to support Thomson's activities and
endeavors in the field of satellite communications.

      (c) In consideration for Orders awarded by Thomson to WSI during the
period commencing on the date of the Closing and ending on the date which is two
years and 183 days following the date of the Closing (the "Award Period"), WSI
shall issue to Thomson newly-issued Shares as follows:

      (i)   when the aggregate value of all Orders awarded by Thomson to WSI
            during the Award Period equals or exceeds $1.5 million, WSI shall
            issue to Thomson a number of Shares equal to 1% of the then
            outstanding share capital of WSI, excluding employee and other
            incentive stock options (collectively, "Employee ISOs"); and

      (ii)  for each of the first four subsequent increments of $3 million of
            aggregate value of all Orders in excess of $1.5 million awarded by
            Thomson to WSI during the Award Period, WSI shall issue to Thomson
            an additional number of Shares equal to 1% of the then outstanding
            share capital of WSI, excluding Employee ISOs.

                                                                  Execution Copy


For purposes of this Paragraph 9(c), the term "Order" means a confirmed, legally
binding order for goods or services that has been duly awarded by Thomson and
duly accepted in writing by WSI; provided, however, that, except for orders in
connection with the Triband Project, orders for goods or services procured
exclusively in connection with research and development projects shall not be
considered "Orders" for the purposes hereof. Any Shares issued to Thomson
pursuant to this Paragraph 9(c) shall be limited to a maximum of five "1%"
grants, where "1%" is determined as 1% of the outstanding share capital at the
time of the grant, excluding Employee ISOs. These "1%" grants are not
retroactive and therefore will not result in the readjustment of previously
granted "1%" share amounts. The parties acknowledge that previously granted "1%"
amounts may no longer represent exactly 1% of the outstanding share capital of
WSI at the time of additional 1% grants since the outstanding share capital of
WSI will change by virtue of these grants and other authorized changes.

      (d) The obligations of good faith effort set forth in Paragraphs 9(a) and
9(b) above shall not give rise to a right to recover damages in favor of WSI,
Thomson or any other person.

   10. Termination. This Agreement shall terminate on November 15, 1995 if it
has not been accepted and agreed to by WSI prior thereto and may be terminated
by Thomson, without any liability or other obligation of Thomson, by written
notice delivered by WSI at its address set forth at the head of this Agreement
at any time prior to the Closing, in the event Thomson is not satisfied with the
information regarding WSI contained in the Offering Documents or otherwise
disclosed to Thomson in the course of Thomson's due diligence as a private
investor in accordance with applicable law. In the event that, not later than
the day prior to the Closing, Thomson has not provided WSI with written
acknowledgement that (i) it has satisfied its due diligence investigation for
purposes of Paragraphs 9(a) and 9(b) above (without prejudice to the survival of
the representations and warranties of WSI hereunder pursuant to Paragraph 11)
and (ii) the conditions to the Closing set out in Paragraph 9(c) above has been
satisfied, this Agreement may be terminated by WSI at anytime thereafter prior
to or at the Closing, without any liability or other obligation headquarters
address in Paris.

   11. Miscellaneous. All of the respective representations and warranties of
WSI and Thomson hereunder shall survive the Closing. This Agreement shall be
governed by, and construed in accordance with, the law of the State of New York
without reference to choice of law principles. This Agreement constitutes the
entire understanding of the parties hereto with respect to the subject matter
contained herein. Time shall be of the essence in this Agreement. All disputes
relating to money damages arising in connection with this Agreement shall be
finally resolved under the Rules of Conciliation and Arbitration of the
International Chamber of Commerce by three

                              INVESTMENT AGREEMENT

     THIS INVESTMENT AGREEMENT is made the 12 day of February 1996 BY AND
          BETWEEN:

     Shiron Satellite Communications (1996) Ltd., located at 14 Kiryat Sefer,
          Tel Aviv, Israel, a company registered in Israel, (the "Company") and

     Worldcomm Systems, Inc., located at 375 Oser Avenue, Hauppauge, N.Y., a
          company incorporated under the laws of the State of Delaware ("WSI").

     WHEREAS the Company is in the business of developing, producing and
          marketing modems for satellite communications; and

     WHEREAS Shiron Advanced Communication Ltd. ("Shiron"), an affiliate of the
          Company, has received a grant from the BIRD foundation to develop and
          market a satellite modem (the "Modem") in accordance with the details
          set forth in the grant application, and

     WHEREAS the Company shall acquire from Shiron the full ownership in certain
          know-how related to the developement of a satellite modem in exchange
          for shares in the Company, and shall receive the rights granted to
          Shiron pursuant to its portion in the BIRD Foundation grant
          application; and

     WHEREAS WSI wishes to invest in the Company, and the Company wishes to
          accept such investment, in each case subject to the terms and
          conditions set forth herein.

NOW THEREFORE IT IS ACCORDINGLY AGREED AS FOLLOWS:

1.   SUBSCRIPTION

     1.1  Subject to the terms and conditions of this Agreement, at the Closing
          the Company shall issue and allot to WSI such number of Ordinary
          Shares of the Company (the "Shares") which, upon issuance, shall
          constitute 10% (ten percent) of the issued share capital of the
          Company, free and clear of all liens, charges, claims, encumbrances,
          security interest or third party rights.


     1.2  Upon the Company completing a first laboratory prototype (the
          "Prototype") of the Modem, WSI will subscribe for an additional 9%
          (nine percent) of the issued Shares, free and clear of all liens,
          charges, claims, encumbrances, security interest or third party
          rights.

     1.3  WSI will also have an option to subscribe for an additional 1% (one
          percent) of the issued shares at any time during the 18 month period
          following the second subscription under Section 1.2, free and clear of
          all liens, charges, claims, Encumbrances, security interest or third
          party rights.

<PAGE>

                                       2


     1.4  WSI will also have an option to subscribe for an additional 10% (ten
          percent) of the issued Shares, free and clear of all liens, charges,
          claims, encumbrances, security interest or third party rights, at the
          same price per Share as paid for the first subscription, at any time
          during the 18 months period following the first subscription under
          Section 1.2 if WSI purchases and pays for at least $750,000 worth of
          products from SatMod during the 18 months period, or at a Share price
          to be negotiated during the 24 months period following the first
          subscription under Section 1.2, if WSI purchases and pays for at least
          $1,500,000 worth of products from SatMod during the 24 months period.

     1.5  In the event that the Company decides to issue additional Shares in
          the Company to other investors, the Company shall so inform WSI.
          Shares issued to other investors, during the 12 months period
          following the first subscription under Section 1.2, shall come from
          Shiron's percentage. After the 12 months period following the first
          subscription, Shares issued to other investors will dilute all
          shareholders and WSI shall have the option to purchase that number of
          additional Shares at the same price as the price to be paid by the
          other investors, in order to maintain WSI's holdings in the Company at
          20% (twenty percent). The foregoing notwithstanding, the Company shall
          be entitled to issue Shares constituting up to 10% (ten percent) of
          its Share capital to its employees. Shares issued to employees within
          the first 18 months shall come from Shiron's percentage. After 18
          months, Shares issued to employees will dilute all shareholdings.
          However, WSI will have the option to purchase additional Shares to
          maintain its percentage, within 3 months after such 18 month period.
          The price per Share in this case will be the same as the price paid by
          the last non-strategic investor.


     1.6  WSI shall hold its Shares in the Company, and shall not sell or
          transfer them, in whole or in part, for at least three (3) years from
          the date of this Agreement.

          2.   THE SUBSCRIPTION PRICE

     The subscription price to be paid by WSI for the Shares shall be equal to
     the sum of (a) US $150,000 (one hundred and fifty thousand dollars) at
     Closing, (b) US $135,000 (one hundred and thirty five thousand dollars)
     upon presentation to WSI of the Prototype and (c) US15,000 (fifteen
     thousand dollars) upon exercise of the option to subscribe for 1% of the
     shares.

3.   DIRECTORS

     Immediately upon payment of that portion of the subscription price, as set
     forth in Section 2(a) above, WSI shall be entitled to appoint one (I)
     director to the board of directors of the Company and Shiron shall be
     entitled to appoint four (4) directors to the board of directors of the
     Company. If WSI chooses not to appoint a director at such time, it shall be
     entitled to have a representative attend board meetings as an observer
     until such time as it chooses to appoint a director. In the event that WSI
     fails to meet any of its additional investment obligations thereafter,
     pursuant to Section 2(b) above or to the Articles of Association, then WSI
     shall lose the right to appoint a director or an observer.

          APPLICABLE STATE SECURITIES LAWS.

The legend set forth above shall be removed by the Company from any certificate
evidencing Purchased Shares upon delivery to the Company of an opinion by
counsel, reasonably satisfactory to the Company, that a registration statement
under the Act is at that time in effect with respect to the legended security or
that such security can be freely transferred in a public sale without such a
registration statement being in effect and that such transfer will not

the Company to the Investor under this Agreement are subject to the fulfillment
or waiver on or before the Closing of each of the following conditions:

          6.1 Representations and Warranties. The representations and warranties
of Investor contained in Section 4 shall be true and correct in all material
respects on the date of the Closing with the same effect as though such
representations and warranties had been made on and as of the Closing.

          6.2 Payment of Purchase Price. The Investor shall have delivered to

Section 2.

          6.3 Securities Exemptions. The offer and sale of the Purchased Shares

requirements of the Act and the registration and/or qualification requirements

          7.1 Grant of Option. The Company does hereby grant to Investor an
irrevocable option (the "Option") to purchase an additional Fifteen Percent
(15%) of the then issued and outstanding shares of the Company's Common Stock,
on an after acquired basis (the "Option Shares"), pursuant to the terms and
conditions of this Agreement. It being the intention of the parties that
investor shall have the right to acquire and maintain, should Investor so elect,
a Twenty Percent (20%) ownership interest in the Company.

          7.2 Option Term. The Option term shall commence on the date hereof and
shall continue for a period of two (2) years from the date hereof (the "Option
Term").


                                        8

<PAGE>

          7.3 Option Exercise. (a) Investor may exercise the Option at any time
during the Option Term by giving written notice (the "Option Notice") of its
intention to do so to the Company. The date notice is given shall be referred to
as the "Exercise Date".

               (b) Within thirty (30) days after the Option Notice has been
delivered by Investor to the Company, the Company shall issue, transfer and
deliver to Investor certificates representing Fifteen Percent (15%) of the then
issued and outstanding shares of Common Stock of the Company, on an after
acquired basis. The Option Shares shall be free and clear of all liens, security
interests and other encumbrances, and upon payment as provided in Section 7.4
below, such Option Shares shall be duly and validly issued, fully paid and
nonassessable. Such Option Shares shall be recorded on the books of the Company
in the name of Investor.

          7.4 Purchase Price. (a) The purchase price for the Option shares shall
be based upon the Company's projected Fiscal Year 1998 net income of Three
Hundred Eighty Three Thousand Nine Hundred Ninety-Eight Dollars ($383,998) as
illustrated in Exhibit G. Such projected net income shall then be multiplied by
a price to earnings multiplier of twenty (20) times, which product shall be
multiplied by the percentage of the Company being acquired by Investor pursuant
to the Option, and which product will then be subject to a twenty percent (20%)
discount (the "Purchase Price"). This aforementioned purchase term applies to
shares purchased on or prior to August 30, 1997. The Purchase Price shall be
paid by Investor to the Company at the closing in cash or by certified check.

               (b) Option shares acquired after August 30, 1997, but no later
than August 30, 1998, will be based upon the Company's then most recent
projected Fiscal Year 1999 net income, which in no case shall be less than the
Purchase Price set forth in Section 7.4(a) above or greater than One Million
Thirty Three Thousand Five Hundred Thirty Eight Dollars ($1,033,538), as
illustrated in Exhibit G. The net income projected in Exhibit G will serve as
the basis for the maximum possible purchase price. Such projected net income
shall then be multiplied by a price to earnings multiplier of twenty (20) times,
which product shall be multiplied by the percentage of the Company being
acquired by Investor pursuant to the Option, and which product will then be
subject to a twenty percent (20%) discount (the "Secondary Purchase Price"). The
Secondary Purchase Price shall be paid by Investor to the Company at the closing
in cash or by certified check.

          7.5 Closing. The Option Notice shall specify a date (the "Closing
Date") not less than thirty (30) and not more than forty-five (45) days
subsequent to the date of the Option Notice for the closing (the "Closing");
provided that, if no Closing Date is specified in the Option Notice, the Closing
Date shall be the first business day that is at least forty-five (45) days after
the Exercise Date. The Closing shall occur at the offices of the Company at
10:00 a.m. or at such other time, place and date as may be agreed upon by the
Company and Investor.

          7.6 Cooperation. At the Closing and thereafter, each party shall
execute and deliver to the other party such instruments and documents as are
reasonably required to accomplish and conclude the transactions contemplated
under this Section 7; and the Company shall also provide copies of any corporate
books and records reasonably requested by Investor on or prior to Closing.

          7.7 Conditions to Closing. Investor's obligation to close following
the exercise of the Option shall be subject to there having been no material
adverse change in the condition, value or prospects of the Company between the
Exercise Date and the Closing Date.

     8. RIGHT OF FIRST REFUSAL.

          8.1 General. Investor shall have the right of first refusal to
purchase its "Pro Rata Share" (as defined below), of all (or any part) of any
"New Securities" (as defined in Section 8.2) that the Company may from time to
time issue after the date of this Agreement. Investor's "Pro Rata Share" for
purposes of this right of first refusal is the ratio of (a) the number of shares
of Common Stock held by Investor to (b) the total number of shares of Common
Stock of the Company then outstanding prior to the issuance of the subject New
Securities.

          8.2 New Securities. (a) "New Securities" shall mean any Common Stock
or preferred stock of the Company, whether now authorized or not and rights,
options or warrants to purchase such Common Stock or preferred stock, and
securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or preferred stock; provided however, that
the term "New Securities" does not include:

                    (i) shares of the Company's Common Stock issued in
connection with any stock split or stock dividend;

                    (ii) securities offered by the Company to the public
pursuant to a registration statement filed under the Act;

                    (iii) shares of common stock, or options exercisable
therefor, issuable to officers, directors, consultants and employees of the
Company or any subsidiary pursuant to any plan, agreement or arrangement
approved by a vote of not less than a majority of the Board of Directors of the
Company; and

                    (iv) securities issued solely in consideration for the
acquisition (whether by merger or otherwise) by the Company or any of its
subsidiaries of all or substantially all of the stock or assets of any other
entity.

               (b) In the event securities of the Company are issued in the
manner contemplated by Section 8.2(a)(iii) (in excess of the 500,000 shares
reserved for issuance under the Equity Incentive Plan) or Section 8.2(a)(iv),
then in such event Investor shall have the right of first refusal to purchase
unissued shares of the Company's securities sufficient for Investor to maintain
its Pro Rata Share.

          8.3 Procedures. In the event that the Company proposes to undertake an
issuance of New Securities or an issuance pursuant to Section 8.2(a)(iii) (in
excess of the 500,000 shares reserved for issuance under the Equity Incentive
Plan) or Section 8.2(a)(iv), it shall give to Investor written notice of its
intention to issue such securities (the "Notice"), describing the type of such
securities and the price and the general terms upon which the Company proposes
to issue such securities. Investor shall have thirty (30) days from the date of
mailing of any such Notice to agree in writing to purchase Investor's Pro Rata
Share of such securities for the price and upon the general terms specified in
the Notice (which shall be the


                                       10

<PAGE>

same price and terms as are offered to third parties) by giving written notice
to the Company and stating therein the quantity of such securities to be
purchased (not to exceed Investor's Pro Rata Share). If Investor fails to so
agree in writing within such thirty (30) day period to purchase Investor's full
or partial Pro Rata Share of an offering of such securities, then Investor shall
forfeit the right hereunder to purchase that part of its Pro Rata Share of such
securities that it did not so agree to purchase.

          8.4 Failure of Exercise. In the event that Investor fails to exercise
in full the right of first refusal within such thirty (30) day period, then the
Company shall have one hundred twenty (120) days thereafter to sell the New
Securities or the securities described in Section 8.2(a)(iii) or Section
8.2(a)(iv) with respect to which the Investor's rights of first refusal
hereunder were not exercised, at a price and upon general terms not more
favorable to the purchasers thereof than specified in the Company's Notice to
Investor. In the event that the Company has not issued and sold the New
Securities or the securities described in Section 8.2(a)(iii) or Section
8.2(a)(iv) within such one hundred twenty (120) day period, then the Company
shall not thereafter issue or sell any such securities without again first
offering such securities to Investor pursuant to this Section 8.

     9. CERTAIN COVENANTS AND AGREEMENTS

          9.1 Indemnification by the Company. The Company agrees to indemnify,
defend and hold Investor harmless, at any time after the Closing, from and
against all losses, costs, damages, liabilities, interest, penalties,
settlements, judgments or expenses, including, but not limited to, reasonable
attorney's fees and expenses, asserted against, resulting from, imposed upon or
incurred by Investor directly or indirectly, arising out of or in connection

the Company made in or pursuant to this Agreement; and/or (ii) any breach or
non-fulfillment of any covenant or agreement of the Company contained in this

the Company's undertaking an initial public offering, it will permit Investor to
include in the registration statement filed by the Company in connection with
such initial public offering all of the Common Stock of the Company that
Investor holds and has requested be registered, subject to the right of the
Company to limit the number of such shares to be included in such registration
statement if the managing underwriter of such initial public offering reasonably
determines that the inclusion of such shares in such offering would materially
adversely affect the marketability of such offering by the Company.

     10. MISCELLANEOUS.

meeting of the Company, Investor's nominee shall be appointed to the Board of

Share to be delivered to the Selling Founder for the proposed sale, transfer or
disposition, and (iii) all other material terms and conditions of the proposed
transaction.

and on the terms and conditions specified in the Notice. The Purchaser must
exercise such option, no later than 45 days after such Notice is deemed under
Section 8.4 hereof to have been delivered to it, by written notice to the
Selling Founder.

          4.2 In the event the Purchaser duly exercises his option to purchase
all or part of the Offered Shares, the closing of such purchase shall take place
at the offices of the Company on the date five days after the expiration of such

Purchaser for the Offered Shares consists of property other than cash or a
promissory note, the consideration required to be paid by the Purchaser
exercising his option under Section 4 hereof may consist of cash equal to the
value of such property, as determined in good faith by agreement of the Selling
Founder and the Purchaser.

General Scope of Responsibilities

The purpose of this document is to outline an initial service and engineering
scope of responsibilities for the NSX/AppliedTheory relationship. This document
does not imply or discuss funding, capital costs or business relationships. The
use of words such as provide, responsible and manage are used to define
functional ownership only.

A.   NetSat Express Internet Network Operations Center

     The Internet Network Operations Center is multi-function Center that
     includes IP server based services, LAN and WAN interconnects and systems,
     monitoring and management controls and support services for customers. NOC
     functions are described in various sections of this document.

     1.   AppliedTheory will design the Internet components of the NetSat USA
          NOC in the WSI/NSX facility in Hauppauge, New York. This includes
          Internet Access, Backbone Connectivity, Router configuration and
          maintenance and integration of Internet Services.

     2.   NSX engineering will take an active role in this design.

     3.   NSX will be responsible for the building of this facility.
          AppliedTheory will advise on the construction of the Internet related
          equipment and interfaces.

     4.   AppliedTheory will be responsible for the initial management and
          operations of the Internet aspects of facility until they can train
          the NetSat staff for a technology transfer. Both AppliedTheory and NSX
          will be responsible for supplying staff during this period. The time
          period of this technology transfer has not been determined, but will
          primarily focused on handing off the responsibilities to NSX quickly.

     5.   Upon completing this technology transfer, AppliedTheory will provide
          phone support and under emergency situation could supply on-site help.

     6.   Both Engineering groups believe it is necessary to jointly more
          explicitly define the following items before relevant technical design
          can progress.

          a.   Services provided from this NOC such as News, Mail, FTP and
               administrative services including the initial and long-term
               volume and capacities required.

          b.   Interfaces to the Hughes Network System DirecpC and PES Networks


                                     Page 1

<PAGE>

          c.   DNS server responsibilities

          d.   Distribution of Internet Servers and services (FTP, DNS, etc.)
               function between USA NOC and Regional Uplink Facilities.

          e.   Monitoring, management and trouble tracking systems

B.   Internet Access

     1.   AppliedTheory will provide Internet access from their Deer Park POP to
          the NetSat Express/WSI facility. Upgrades and redundancy will be
          added as required.

     2.   AppliedTheory is responsible for solving Internet problems with this
          link and other parts of the public Internet.

     3.   AppliedTheory will provide the Backbone Router at the NetSat Express
          facility. The Backbone router will be considered part of the
          AppliedTheory Backbone Network.

          Both groups agree that CISCO are the routers of choice.

          Both AppliedTheory and NSX will jointly engineer the Backbone Router
          at the NSX facility. Jim Canniff and Dave Barr will jointly agree on
          the details and capabilities of this router. CISCO Series 4000 and
          7000 routers will be considered. Sparing and Cisco maintenance will
          also be determined at this time.

          AppliedTheory will software manage this router. NSX will hardware
          manage the router with the help of AppliedTheory. There will be a
          joint installation. AppliedTheory and NSX will jointly maintain the
          router.

          NSX will provide a POTS (phone) line and modem at the router location
          so that AppliedTheory can have out-of-band access to the router.
          NSX/WSI will have SNMP and read access to this router. AppliedTheory
          will have read/write and SNMP access to this router.

          AppliedTheory will use this router to train NSX in the use and
          configuration of Backbone routers. Both parties should keep in mind
          that this router will likely be carrying commercial traffic during
          periods of training and the training sessions can not disrupt the
          daily operations of the network. (This router will be treated as a
          "production" router.)

          AppliedTheory will retain long term soffware management of this router
          and other AppliedTheory Backbone routers.


                                     Page 2

     4.   The Internet Connectivity of the WSI corporate network will be
          transitioned from PSI to AppliedTheory. WSI and AppliedTheory will
          coordinate this effort. WSI will cut over from PSI to AppliedTheory
          during or after the building move. (Estimated date is 01-April-97.)

          WSI and NSX will be using this router and Internet link for their
          companies' business purposes (in addition to the eventual NOC and
          customer Internet traffic).

          AppliedTheory will consider WSI to be a NSX customer and the WSI use
          will be limited to its corporate Internet business unless mutually
          agreed arrangements are addressed. WSI will be limited in bandwidth
          based on WSI requirements, NSX management of hardware configuration
          and AppliedTheory pricing.

C.   NetSat Express Backbone Requirement

     1.   AppliedTheory will provide the management of both Router to Router
          terrestrial and satellite Backbone links between the NSX NOC and their
          Regional Uplink Facilities for a period of one year (to be reviewed
          quarterly). AppliedTheory will train NSX on the Backbone Circuit
          Management for the eventual technology transition.

     2.   AppliedTheory will provide Backbone router software management,
          configurations, monitoring, reporting on all Backbone routers and
          their interfaces for a period of one year (to be reviewed quarterly).
          NSX/WSI will have SNMP and read access to the Backbone routers.
          AppliedTheory will have read/write and SNMP access to the Backbone
          Routers. AppliedTheory will train NSX on the Backbone Router
          Management for the eventual technology transition.

     3.   Both AppliedTheory and NSX will jointly engineer the Backbone Routers.
          Jim Canniff and Dave Barr will jointly agree on the details and
          capabilities of this router. Sparing and Cisco maintenance will also
          be determined at this time.

     4.   NSX is responsible for Router to Router configuration across the
          satellite links. AppliedTheory will support NSX with problem solving
          and trouble-shooting.

     5.   Both parties agree that CISCO is the router of choice for the Backbone
          network.

     6.   The responsibility of ordering, payment and "Letter of Agency" for
          Backbone routers and terrestrial circuits will be determined.

     7.   NSX will manage and maintain the Local Area Networks inside the USA
          NOC and Regional Uplink Facility. AppliedTheory will provide advise.


                                     Page 3

<PAGE>

     8.   Router installation and hardware maintenance inside the Regional
          Uplink Facility will be the responsibility of NSX with phone support
          from AppliedTheory

     9.   NSX will provide POTs line and modem to router locations inside the
          Regional Uplink Facilities.

     10.  AppliedTheory will provide routing protocol specifications for both
          IGP and EGP routing functions. AppliedTheory will provide a scaleable
          network routing plan for the Backbone network

D.   NetSat Remote Customer Locations

     1.   NSX will be responsible for support of the equipment at the customer
          sites.

     2.   In customer locations which have routers, AppliedTheory will advise on
          router selection and configurations (set a series of standard hardware
          and software configurations).

     3.   NSX will install, manage and maintain the routers at these sites.

     4.   NSX is responsible for the satellite links to and from these sites.

     5.   AppliedTheory should not be responsible for local ISP connectivity
          problems when remote DirecPC users select local ISPs as their path
          from the customer site to the Internet.

     6.   AppliedTheory will provide recommendations on the equipment, software
          and configurations for routers, Internet servers, terminal servers,
          modems and any other components for the proposed "cookie cutter" ISP
          sites.

E.   Customer Support and NOC Staffing 

     1.   Remote sites are NSX customers.

     2.   NSX is responsible for billing these customers. AT will help extract
          and collect this data.

     3.   AppliedTheory will provide a NOC Staffing Plan to NSX for 7X24
          customer support.

          AT will document the "Support Plan" for NSX. The Support Plan will 
          include:

          a.   Mission
          b.   Staffing Plan
          c.   Equipment and software requirements
          d.   Job Description


                                     Page 4

<PAGE>

          e.   Schedule Plan
          f.   Training Plan
          g.   Outline Procedures and Policies

          AppliedTheory will provide temporary customer support while NSX builds
          its own support infrastructure. This support could be provided out of
          the AppliedTheory support headquarters in Syracuse or NYC.

          AppliedTheory to NSX customer support can be transitioned on a shift
          by shift basis as NSX grows.

          NSX strongly desires that all calls directed to this 7x24 customer
          support have the phone answered as "NetSat Express". NSX and AT will
          jointly address this issue.

          In order to support the services and products supplied by
          AppliedTheory, even after the above mentioned transition period, the
          AppliedTheory customer support facility will be available to NSX
          employees. NSX believes this support should also extend to specified
          "NSX Teaming Partners" at Regional Uplink Facilities.

          NSX and AT will work jointly to develop a support plan that allows the
          'NSX Teaming Partners' at the Regional Uplink Facilities to be
          supported by the terms and conditions of the MOU and contracts.

          Before AppliedTheory can provide any future or temporary customer
          support functions for NetSat Express's customers, a definition of the
          Products and Services offered and formal procedures and guidelines
          relating to this customer service need to be jointly established. Also
          these procedures and guideline must address the "escalation pathes"
          which must be followed when a customer service issue warrants a level
          of support for which the support staff is not normally prepared to
          handle.

     4.   End-user documentation is the responsibility of NSX.

     5.   AppliedTheory will provide to NSX documentation and specifications for
          services that are designed by AppliedTheory or jointly. This
          documentation may be incorporated into NSX end-user manuals.

     6.   AppliedTheory will be responsible for monitoring and trouble-shooting
          the entire network segment from the Internet to the Backbone Routers
          at the NOC and Regional Uplink Facilities. Since NSX will often have
          personnel at these sites, they will be available to provide
          assistance.

     7.   AppliedTheory will provide daily monitoring reports via Web interface
          for all AppliedTheory monitored and managed interfaces.


                                     Page 5

1.   AGREEMENT TO PURCHASE AND SELL STOCK. The Company shall sell to the
     Investor at the Closing, and the Investor shall purchase from the Company
     at the Closing, 190,000 shares of the Class A Preferred, at a price of
     $1.32 per share. The shares of Class A Preferred Stock purchased and sold
     pursuant to this Agreement will be collectively hereinafter referred to as
     the "Purchased Shares."

2.   OPTION TO PURCHASE COMMON STOCK. The Company further grants to the Investor
     the option to purchase, at any time until 5:00 P.M., New York City time, on
     July 31, 2001, up to the number specified below of fully paid and
     non-assessable shares of the Company's Common Stock, $.01 par value
     ("Common Stock") at a price of $1.50 per share of Common Stock (the
     "Exercise Price") payable in cash, by certified check or official bank
     check or by wire transfer, subject to adjustment as provided below. The
     shares of Common Stock which may the purchased upon exercise of such option
     are collectively hereinafter referred to as the "Option Shares."

     2.1. As used in this paragraph, the term "Partially Diluted Common Stock"
          means the sum of (i) the number of shares of common stock actually
          outstanding at the time of reference, less any shares of common stock
          issued upon exercise of the option granted herein or conversion of the
          Class A Preferred Stock plus (ii) the number of shares of common stock
          issuable upon conversion of any outstanding convertible securities of
          the Company other than the Class A Preferred Stock plus (iii) the
          number of shares of common stock issuable upon exercise of all
          outstanding warrants, options, or other rights to acquire common stock
          other than the option granted herein. The term "Fully Diluted Common
          Stock" means the sum of (i) the number of shares of common stock
          actually outstanding at the time of reference, including all shares of
          common stock issued upon exercise of the option granted herein or upon
          conversion of the Class A Preferred Stock plus (i) the number of
          shares of common stock issuable upon conversion of any outstanding
          convertible securities of the Company including the Class A Preferred
          Stock plus (iii) the number of shares of common stock issuable upon
          exercise of all outstanding warrants, options, or other rights to
          acquire common stock including the option granted herein. If the
          option is exercised by the later of (x) 2


<PAGE>

          years from the date of this Agreement and (y) the first anniversary of
          the commencement of commercial operations at the Company's first
          commercial hub serving a multi-national market, then the number of
          shares constituting the Option Shares shall be the greater of 100,000
          shares and the number of shares produced by the formula specified
          below (the "Formula Number"). If the option is not exercised within
          the period specified in the preceding sentence, the number of shares
          constituting the Option Shares shall be 100,000. The Formula Number
          shall be that number which satisfies both of the following two
          conditions:

          2.1.1. the sum of the Formula Number and the Partially Diluted Common
                 Stock immediately before exercise of the option shall equal
                 81% of the Fully Diluted Common Stock immediately following
                 exercise of the option, and

          2.1.2. the Formula Number shall equal 10% of the Fully Diluted Common
                 Stock immediately following exercises of the option.

          Mathematically, the Formula Number shall be the result of solving for
          FN the following two equations:

          PDCS+FN=0.81*FDCS

          FN=0.10*FDCS

          where PDCS is Partially Diluted Common Stock immediately before
          exercise of the option and FDCS is Fully Diluted Common Stock
          immediately following exercise of the option.

2.2. Subdivision and Combination. In case the Company shall at any time
     subdivide or combine the outstanding shares of Common Stock, the Exercise
     Price shall forthwith be proportionately decreased in the case of
     subdivision or increased in the case of combination.

2.3. Adjustment in Number of Shares. Upon each adjustment of the Exercise Price
     pursuant to the provisions of this Section 2, the number of shares of
     Common Stock issuable upon the exercise of the option shall be adjusted to
     the nearest full share by multiplying the Exercise Price in effect
     immediately prior to such adjustment by the number of shares of Common
     Stock issuable upon exercise of the option immediately prior to such
     adjustment and dividing the product so obtained by the adjusted Exercise
     Price.

2.4. Reclassification, Consolidation, Merger, Etc. In case of any
     reclassification or change of the outstanding shares of Common Stock (other
     than a change in par value to no par value, or from no par value to par
     value, or as a result of a subdivision or combination), the Investor shall
     thereafter have the right to purchase the kind and number of shares of
     stock and other securities and property which would have been received upon
     such reclassification or change if the Investor had exercised the option
     granted herein immediately prior to such transaction, at a price equal to
     the product of (x) the number of shares issuable upon exercise of the
     option and (y) the Exercise Price in effect immediately prior to the record
     date for such reclassification or change.

3.   CLOSING. The purchase and sale of the Purchased Shares will take place at
     the offices of the Investor on August 2, 1996 or at such time and place as
     the Company and Investor mutually agree upon (which time and place are
     referred to in this Agreement as the "Closing"). At the Closing, the
     Company will deliver to the Investor a certificate representing the number
     of Purchased Shares that the Investor has agreed to purchase against

            SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO
            RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE

            a public sale without such a registration statement's being in

                              EMPLOYMENT AGREEMENT

          THIS AGREEMENT made as of January 27, 1997 by and between David E.
     Hershberg, a resident of Port Jefferson, New York (the "Executive"), and
     Worldcomm Systems, Inc., a corporation organized and existing under the
     laws of the State of Delaware (the "Company").

                                    RECITALS

The Executive is currently the Chairman of the Board and Chief Executive Officer
of the Company. The Board of Directors of the Company desires assurance that the
Executive will continue as its leader for at least the next three years. The
Company further wishes to assure itself of continuity of management in the event
of any actual or threatened change in the control of the Company, and believes
it is important that Executive be able to assess and advise the Company whether
supporting a change in control would be in the best interests of the Company and
its shareholders without being influenced by the uncertain effect of such a
change upon Executive's role within the Company. The Executive is willing to
commit to undertake his responsibilities as Chairman of the Board and Chief
Executive Officer of the Company on the terms and conditions hereinafter set
forth. The parties therefore agree as follows. 

1. Employment and Term. The Company hereby employs the Executive, and the
Executive hereby accepts employment with the Company, for the period commencing
on the date hereof and continuing until the third anniversary of such date and
from year to year thereafter, unless terminated by either party by written
notice of termination given to the other party. Termination by the Company of
the employment of Executive hereunder shall be effective (a) 90 days after the
date such notice is given if such termination is pursuant to Sections 0 or 0
below, or (b) immediately upon the date such notice is given if such termination
is pursuant to Section 0 below.

2. Responsibilities. During the term of his employment, the Executive shall
devote his full time, attention, loyalty, skill and efforts to the performance
of his responsibilities to the Company as Chairman of the Board and Chief
Executive Officer. The Company will not during the terms of this Agreement
demote the Executive or reduce his responsibility as the Chairman of the Board
and Chief Executive Officer, or otherwise reduce his stature in the Company.

3. Compensation. The Company shall pay or provide to the Executive, and the
Executive shall accept, the following as full compensation for all services
rendered hereunder. All compensation shall be subject to all applicable
withholding and similar requirements.

(a) Base Salary. The Company shall pay to the Executive a base salary (the "Base
Salary") at the annual rate of $165,000. The Base Salary shall be reviewed on an
annual basis and may be increased from time to time at the discretion of the
Board of Directors.

(b) Bonus or Incentive Compensation. Executive will participate in any bonus or
incentive compensation plan (including stock option and stock bonus plans)
approved by the Board of Directors for senior management of the Company.

(c) Benefits. The Company shall provide to the Executive, without any payment or
contribution by the Executive or members of his family, throughout his
employment by the Company the following benefits:

          (i) Life Insurance. A life insurance policy in the amount of three
times the Base Salary, payable to the beneficiaries designated by the Executive.

          (ii) Disability Insurance. Disability Insurance providing the
Executive with monthly payments during the period of his disability (after
termination of his employment) in an amount equal to 1/12th of his then
applicable annual Base Salary immediately prior to his disability. If the
disability insurance policy should begin payment while the Executive is still
being compensated by the Company under the terms of this Agreement, the
Executive will reimburse the Company for all portions of such payments which
cause his total compensation to exceed the amounts otherwise payable to the
Executive under the terms of this Agreement.

          (iii) Medical. Medical insurance protection for the Executive and his
family at least as favorable to the Executive and his family as the protection
and plan being made available to them on the date of this Agreement. In
addition, if not covered by insurance, the Company shall provide the Executive
with an annual health checkup.

          (iv) Professional Services Allowance. The Company will pay up to
$2,500 per year for Executive's tax planning and preparation and/or other
financial planning services used by the Executive.

          (v) Automobile. The Company will furnish the Executive, without cost
to him, with a Company-owned or leased automobile of the make and model then
authorized by the Company's policy or provide an allowance for that purpose.
<PAGE>

          (vi) Other. Such other benefits, not duplicative of the foregoing,
which the Board of Directors may now or in the future make available to its
senior executives.

4. Support and Expenses. The Company shall provide the Executive with an office,
staff and other support appropriate for the Chairman of the Board and Chief
Executive Officer of an organization of the stature of the Company, and shall
pay or reimburse the Executive for all reasonable travel and other expenses
incurred by him in connection with the performance of his services under this
Agreement upon presentation of expense statements or vouchers and such other
supporting information as the Company may from time to time reasonably request.

5. Termination by Company After Initial Term. If the Company shall terminate the
employment of Executive after the end of the third year of this Agreement, for a
reason other than "disability" or "cause," as defined in Section 0 hereof, the
Company shall continue to pay the Executive all of his compensation set forth in
Section 0 hereof through the effective date of termination. Thereafter the
Company shall pay to the Executive any compensation and other benefits which
were vested as of the effective date of termination but payable at a later date.
In addition to all of the foregoing, the Company shall pay to the Executive on
the first business day of the month following the effective date of termination
severance pay (herein called "Severance Pay") in a lump sum equal to 1/12th of
his then applicable annual Base Salary.

6. Termination by Company Prior to End of Initial Term. If the Company shall
terminate the employment of Executive prior to the end of the third year of this
Agreement, for a reason other than "disability" or "cause" as defined in Section
0 hereof, or if the Executive shall terminate his employment after the Company
has committed a material breach of this Agreement, then the Company shall pay to
the Executive as they become due, amounts otherwise payable to the Executive if
he had remained in the employment of the Company until the end of the third year
of this Agreement. In addition, the Company shall (i) forthwith pay Severance
Pay computed in accordance with Section 0 hereof, (ii) thereafter pay all
amounts of compensation and benefits which were vested on the date of
termination but not payable until a later date, including amounts payable under
Section 0(0) hereof, and (iii) comply with Section 0 hereof.

7. Termination for Disability or Cause. The Company may terminate the
Executive's employment due to "disability" if the Board of Directors shall
determine in good faith, that, by reason of physical or mental illness or other
condition continuing for more than one hundred and twenty (120) consecutive days
or for shorter periods aggregating more than one hundred and twenty (120) days
in any period of twelve (12) months (excluding in each case days on which on the
Executive was on vacation), the Executive has been substantially unable to
render services of the character contemplated by this Agreement. The Company may
terminate the Executive's employment for "cause" if the Board of Directors shall
determine in good faith that there shall have been a willful breach by the
Executive in a material manner of his duty of loyalty to the Company. If the
Company shall terminate the employment of Executive for disability or for cause
at any time, the Company shall have no further obligation hereunder except for
payment of Base Salary for services previously rendered, payment or provision of
other compensation or benefits previously vested, and the duty set forth in
Section 0 hereof.

8. Voluntary Termination. If prior to breach of this Agreement by the Company,
the Executive shall resign as an employee during the term of his employment, the
Company shall have no further obligation hereunder except for payment of Base
Salary for services previously rendered, payment or provision of other
compensation or benefits previously vested, and the duty set forth in Section 0
hereof.

9. Insurance after Termination. Except in case of termination voluntarily by the
Executive, or termination for Cause, the Company shall continue coverage of the
Executive and his family under the Company's group life, health and disability
insurance plans for a period of one year following termination. If such plans do
not continue to protect the Executive after termination of employment, the
Company will use its best efforts upon termination of the Executive's employment
for any reason other than death to arrange for transfer from a Company plan to
the Executive (to be carried, except in case of termination for Cause, at the
Company's expense for a period of one year and thereafter at his own expense)
any life, health and disability insurance protection which may be so
transferred.

10. Covenant Not to Compete. The Executive covenants and agrees that, from the
date hereof and until (i) thirty-six months following resignation by the
Executive pursuant to Section 0 hereof, or (ii) in the case of any other
termination of Executive's employment, six months following the date upon which
the final payment of amounts payable to the Executive by the Company by reason
of such termination becomes due, he shall not, either directly or indirectly,
(a) engage in or conduct any business competitive with the Company's business,
whether individually or as an employee, agent, officer, director, owner,
consultant or otherwise, without the prior written 


                                       2
<PAGE>

consent of the Board of Directors of the Company, or (b) induce or attempt to
induce any existing or future employee or consultant of the Company or any of
its Affiliates to leave such employment.

11. Litigation. If litigation shall be brought by either party to enforce or
interpret any provision contained herein and such party (the "prevailing party")
shall prevail on any issue contested in such litigation either through
settlement or judgment in favor of the prevailing party, the other party shall
reimburse the prevailing party for reasonable attorneys' fees and disbursements
incurred by the prevailing party in such litigation, and shall pay prejudgment
interest on any money judgment obtained by the prevailing party calculated at
the rate in effect from time to time designated by the Company's principal bank
as its prime rate from the date of the breach by such other party under this
Agreement.

12. Provisions Becoming Effective upon Change in Control. Beginning on the date
of a Change of Control (as defined below), this Section 0 shall govern
Executive's employment and compensation by the Company and the other matters
referred to herein, and any other employment or severance agreement, arrangement
or policy otherwise applicable to the Executive, including, without limitation,
Sections 0 through 0, shall be superseded by this Section.

(a) Definitions. As used in this Section 0, the following terms shall have the
meanings indicated below.

          (i) "Change of Control" means a change of control of the Company of a
nature that would be required to be reported in response to Item 6(e) of
Schedule 14A of Regulation 14A (or in response to any similar item on any
similar schedule or form) promulgated under the Securities Exchange Act of 1934
(the "Act"), whether or not the Company is then subject to such reporting
requirement; provided, however, that, without limitation, such a Change of
Control shall be deemed to have occurred if:

               (A) any person or group (as such terms are used in connection
with Sections 13(d) and 14(d) of the Act) becomes the "beneficial owner" (as
defined in Rule 13d-3 and 13d-5 under the Act), directly or indirectly, of
securities of the Company representing 35% or more of the combined voting power
of the Company's then outstanding securities;

               (B) the Company is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or

               (C) during any period of twenty-four consecutive months,
individuals who at the beginning of such period constituted the Board of
Directors (including for this purpose any new director whose election or
nomination for election by the Company's stockholders was approved by a vote of
at least two-thirds of the directors then still in office who were directors at
the beginning of such period) cease for any reason to constitute at least a
majority of the Board of Directors. Notwithstanding the foregoing provisions of
this Section 0(0)(0), a "Change of Control" will not be deemed to have occurred
solely because of the acquisition of securities of the Company (or any reporting
requirement under the Act relating thereto) by an employee benefit plan
maintained by the Company for its employees.

          (ii) "Term of Post-Takeover Employment" means the period beginning on
the date of a "Change of Control" and ending on the earliest of:

               (A) Executive's 65th birthday,

               (B) Executive's death,

               (C) the date on which this Agreement terminates in accordance
with Section 0(0), and

               (D) the date on which all rights and obligations of the parties
hereto have been satisfied in accordance with the terms of this Agreement.
Neither the expiration of the Term of Post-Takeover Employment nor the
termination of this Agreement will relieve the Company of the obligation to
provide Executive, in accordance with the terms hereof, the payments, benefits
and coverage to which he has become entitled under this Agreement.

(b) Either the Company or Executive may, by giving 60 days' written notice to
the other party, terminate the Agreement as of the third, or any subsequent,
anniversary of the Change of Control.

(c) Termination of Employment.

          (i) In the event Executive's employment is terminated by the Company
during the Term of Post-Takeover Employment for any reason other than "Cause"
(as defined in Section 0(0)(0) the Company will pay Executive:


                                       3
<PAGE>

               (A) a lump sum cash payment, payable within 30 days of his
termination, equal to 300% of the sum of:

                    (1) Executive's highest annual base salary in effect at any
time prior to his termination, plus

                    (2) the highest aggregate amount included by the Company on
his Form W-2 for fringe benefits provided in any of the three calendar years
prior to his termination, plus

                    (3) his highest bonus for any of the three full fiscal years
of the Company immediately preceding his termination; plus

               (B) a lump sum cash payment, payable within 30 days of his
termination, equal to 300% of the employer contribution made for his benefit
under the Company's 401(k) plan for the last fiscal year of the Company ending
prior to the Change of Control.

          (ii) In the event of a termination described in Section 0(0)(0),
Executive, together with his dependents and beneficiaries, will continue
following his termination to participate fully in accordance with Section 0(0)
in all life insurance plans, accident and health plans and other welfare plans,
maintained or sponsored by the Company immediately prior to the Change of
Control, or receive substantially equivalent coverage (or the full value thereof
in cash) from the Company, until the later of

               (A) the end of Executive's Term of Post-Takeover Employment or

               (B) the first anniversary of his termination.

The period of time between such a termination and the next following anniversary
of the Change of Control will be counted as service with the Company for
purposes of any benefit plan of the Company in which Executive is participating
at the time of the termination.

          (iii) In the event of a termination described in 0(0), Executive will
become immediately entitled to exercise any and all stock options previously
granted to him by the Company notwithstanding any provision to the contrary of
the option or any plan under which it was granted.

          (iv) Upon the occurrence of any breach by the Company of this
Agreement within the meaning of Section 0(0)(0), Executive may give the Company
written notice of his intention to resign effective the 30th day following the
date of such notice. If the Company does not fully remedy such breach within 15
days of the date of such notice, Executive's resignation will become effective
on such 30th day. If Executive resigns in accordance with this Section during
the Term of Post-Takeover Employment, his employment will be deemed to have been
terminated by the Company for reasons other than Cause (and he will be deemed to
have offered to continue to provide services to the Company), and he will be
entitled to all the payments and rights and benefits described in Sections
0(0)(0), 0(0)(0) and 0(0)(0) provided that such payments and rights and benefits
will in no event be less than they would have been had such termination taken
place on the date that the Company first breached this Agreement.

          (v) The following events are breaches by the Company of this Agreement
within the meaning of this Section 0(0)(0):

               (A) any reduction of, or failure to pay, Executive's salary or
bonus as described in Sections 0(0) or 0(0);

               (B) any failure to provide the benefits required by 0(0);

               (C) assignment to Executive of any duties inconsistent in any
respect with his position (including status, offices and titles), authority,
duties or responsibilities as contemplated by Section 0, or any other action by
the Company which results in a diminution of such position, authority, duties or
responsibilities;

               (D) failure after a Change of Control to comply with and satisfy
Section 0(0)(0) or 0(0)(0);

               (E) relocation of the Company's principal executive offices, or
any event that causes Executive to have his principal place of work changed, to
any location outside the area where its corporate headquarters are located at
the time of the Change of Control;

               (F) any requirement by the Company that Executive travel away
from his office in the course of his duties significantly more than the number
of consecutive days or aggregate days in any calendar year than was required of
him prior to the Change of Control; and

               (G) without limiting the generality or effect of the foregoing,
any other material breach of this Agreement by the Company or any successor
thereto or transferee of substantially all the assets thereof.


                                       4
<PAGE>

          (vi) If Executive is dismissed by the Company for Cause, he will not
be entitled to payments, benefits or acceleration of exercisability of options
provided under Sections 0(0)(0), 0(0)(0) or 0(0)(0). "Cause" means only the
willful commission by Executive of theft, embezzlement or other serious and
substantial crimes against the Company. For purposes of this definition, no act
or omission shall be considered to have been "willful" unless it was not in good
faith and Executive knew at the time that the act or omission was not in the
best interest of the Company.

          (vii) If Executive's employment is alleged to be terminated for Cause
or if Executive's right to resign under Section 0(0)(0) is disputed, Executive
may initiate binding arbitration in Suffolk County, New York, before the
American Arbitration Association by serving a notice to arbitrate upon the
Company or, at Executive's election, institute judicial proceedings, in either
case within 90 days of the effective date of his termination or, if later, his
receipt of notice of termination, or such longer period as may be reasonably
necessary for Executive to take such action if illness or incapacity should
impair his taking such action within the 90-day period. The Company agrees

               (A) to pay the costs and expenses (including Executive's counsel
fees), and

               (B) to pay interest to Executive on any amounts ultimately found
to be due to Executive hereunder during any period of time that such amounts are
withheld pending arbitration and/or judicial proceedings. Such interest will be
at a rate of 2% over the base rate most recently announced by the Company's
principle bank prior to the commencement of the arbitration.

          (viii) Termination of employment due to the death or total and
permanent disability of Executive will not be considered a termination for
purposes of this Section.

          (ix) If Executive dies following a termination of employment which
entitled him to benefits under this Section 0(0) but prior to receipt of all
such benefits:

               (A) his beneficiary (as designated to the Company in writing) or,
if none, his estate, will be entitled to receive all unpaid amounts due
hereunder; and

               (B) his beneficiary or estate will be entitled to exercise
options in accordance with Section 0(0)(0) and the terms of the options.

(d) No Obligation to Mitigate. There shall be no requirement on the Executive's
part to seek other employment or otherwise mitigate in order to be entitled to
the full amount of any payments or benefits hereunder.

(e) Limitation.

          (i) Notwithstanding any other provision of this Agreement, and except
as provided in Section 0(0)(0), the payments or benefits to which Executive will
be entitled under Section 0(0) of this Agreement will be reduced to the extent
necessary so that Executive will not be liable for the federal excise tax levied
on certain "excess parachute payments" under section 4999 of the Code.

          (ii) The limitation of Section 0(0)(0) will not apply if:

               (A) the difference between

                    (1) the present value of all payments to which Executive is
entitled under Section 0(0) of this Agreement determined without regard to
Section 0(0)(0), less

                    (2) the present value of all federal, state, and other
income and excise taxes for which Executive is liable as a result of such
payments; exceeds

               (B) the difference between

                    (1) the present value of all payments to which Executive is
entitled under Section 0(0) of this Agreement calculated as if the limitation
of Section 0(0)(0) applies, less

                    (2) the present value of all federal, state, and other
income and excise taxes for which Executive is liable as a result of such
reduced payments. Present values will be determined using the interest rate
specified in section 280G of the Code and will be the present values as of the
date on which Executive's employment terminates (unless it is necessary to use a
different date in order to avoid adverse consequences under section 280G).

          (iii) Whether payments to the Executive are to be reduced pursuant to
Section 0(0)(0), and the extent to which they are to be so reduced, will be
determined by the Executive. Executive may, at the expense of the Company, hire
an accounting firm, law firm or employment consulting firm selected by Executive
to assist him in such determination.


                                       5
<PAGE>

          (iv) If a reduction is made pursuant to Section 0(0)(0), Executive
will have the right to determine which payments and benefits will be reduced.

(f) Expenses.

          (i) It is the intent of the Company that the Executive not be required
to incur any expenses associated with the enforcement of his rights under this
Agreement by legal action or arbitration proceeding because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if Executive determines in good faith that
the Company has failed to comply with any of its obligations under this
Agreement, or if the Company or any other person takes any action to declare
this Agreement void or unenforceable, or institutes any legal action or
arbitration proceeding designed to deny Executive, or to recover from him, the
benefits intended to be provided hereunder, or in the event of actions
instituted as contemplated by Section 0(0)(0), the Company irrevocably
authorizes Executive from time to time to retain counsel of his choice, at the
expense of the Company as hereafter provided, to represent Executive in
connection with any and all actions and proceedings, whether by or against the
Company or any director, officer, stockholder or other person affiliated with
the Company, which may adversely affect Executive's rights under this Agreement.
In addition, notwithstanding any existing or prior attorney-client relationship
between the Company and such counsel, the Company irrevocably consents to
Executive's entering into an attorney-client relationship with such counsel and
agrees that a confidential relationship shall exist between Executive and such
counsel. Without limiting the effect of Section 0(0)(0) or of the foregoing
provisions of this Section 0(0)(0), the Company shall pay or cause to be paid
and shall be solely responsible for any and all attorneys' and related fees and
expenses incurred by Executive as a result of the Company's failure to perform
under this Agreement.

          (ii) Without limiting the effect of Section 0(0)(0), in order to
ensure the benefits intended to be provided to the Executive under such Section,
the Company will, if a Change of Control becomes likely or occurs, use
reasonable efforts to obtain an irrevocable $1,000,000 letter of credit issued
by a bank having combined capital and surplus in excess of $100,000,000, or
alternatively to place that amount in escrow or trust with such a bank, to
provide a fund for the benefit of Executive and other employees of the Company
with similar agreements with respect to enforcement of their rights under their
agreements, all on such terms as the Company shall consider appropriate when it
obtains such a letter of credit or establishes such a fund.

(g) Merger or Acquisition.

          (i) If the Company is at any time before or after a Change of Control
merged with or consolidated into or with any other corporation or other entity
(whether or not the Company is the surviving entity), or if substantially all of
the assets of the Company are transferred to another corporation or other
entity, the corporation or other entity resulting from such merger or
consolidation, or the acquirer of such assets, shall (by agreement in form and
substance satisfactory to Executive) expressly assume the obligations of the
Company under this Agreement. In any event, however, the provisions of this
Agreement shall be binding upon and inure to the benefit of the corporation or
other entity resulting from such merger or consolidation or the acquirer of such
assets, and this Section 0(0) will apply in the event of any subsequent
merger or consolidation or transfer of assets.

          (ii) In the event of any merger, consolidation or sale of assets
described above, nothing contained in this Agreement will detract from or
otherwise limit Executive's right to or privilege of participation in any stock
option or purchase plan or any bonus, profit sharing pension group insurance
hospitalization or other incentive or benefit plan or arrangement which may be
or become applicable to executives of the corporation resulting from such merger
or consolidation or the corporation acquiring such assets of the Company.

          (iii) In the event of any merger, consolidation or sale of assets
described above, references to the Company in this Agreement shall unless the
context suggests otherwise be deemed to include the entity resulting from such
merger or consolidation or the acquirer of such assets of the Company. 

13. Entire Agreement; Amendments. This Agreement contains the entire agreement
and understanding of the parties relating to the subject matter hereof and
supersedes all prior discussions, agreements and understandings of every nature
between them. This Agreement may not be changed or modified, except by an
agreement in writing signed by all of the parties hereto.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed as of
the day of year first above written.

                              EMPLOYMENT AGREEMENT

          THIS AGREEMENT made as of January 27, 1997 by and between Kenneth A.
     Miller, a resident of Huntington, New York (the "Executive"), and Worldcomm
     Systems, Inc., a corporation organized and existing under the laws of the
     State of Delaware (the "Company").

                                    RECITALS

The Executive is currently the Chairman of the Board and Chief Executive Officer
of the Company. The Board of Directors of the Company desires assurance that the
Executive will continue as its leader for at least the next three years. The
Company further wishes to assure itself of continuity of management in the event
of any actual or threatened change in the control of the Company, and believes
it is important that Executive be able to assess and advise the Company whether
supporting a change in control would be in the best interests of the Company and
its shareholders without being influenced by the uncertain effect of such a
change upon Executive's role within the Company. The Executive is willing to
commit to undertake his responsibilities as Chairman of the Board and Chief
Executive Officer of the Company on the terms and conditions hereinafter set
forth. The parties therefore agree as follows. 

1. Employment and Term. The Company hereby employs the Executive, and the
Executive hereby accepts employment with the Company, for the period commencing
on the date hereof and continuing until the third anniversary of such date and
from year to year thereafter, unless terminated by either party by written
notice of termination given to the other party. Termination by the Company of
the employment of Executive hereunder shall be effective (a) 90 days after the
date such notice is given if such termination is pursuant to Sections 0 or 0
below, or (b) immediately upon the date such notice is given if such termination
is pursuant to Section 0 below.

2. Responsibilities. During the term of his employment, the Executive shall
devote his full time, attention, loyalty, skill and efforts to the performance
of his responsibilities to the Company as Chairman of the Board and Chief
Executive Officer. The Company will not during the terms of this Agreement
demote the Executive or reduce his responsibility as the Chairman of the Board
and Chief Executive Officer, or otherwise reduce his stature in the Company.

3. Compensation. The Company shall pay or provide to the Executive, and
the Executive shall accept, the following as full compensation for all services
rendered hereunder. All compensation shall be subject to all applicable
withholding and similar requirements. 

(a) Base Salary. The Company shall pay to the Executive a base salary (the "Base
Salary") at the annual rate of $160,000. The Base Salary shall be reviewed on an
annual basis and may be increased from time to time at the discretion of the
Board of Directors.

(b) Bonus or Incentive Compensation. Executive will participate in any bonus or
incentive compensation plan (including stock option and stock bonus plans)
approved by the Board of Directors for senior management of the Company.

(c) Benefits. The Company shall provide to the Executive, without any payment or
contribution by the Executive or members of his family, throughout his
employment by the Company the following benefits:

          (i) Life Insurance. A life insurance policy in the amount of three
times the Base Salary, payable to the beneficiaries designated by the Executive.

          (ii) Disability Insurance. Disability Insurance providing the
Executive with monthly payments during the period of his disability (after
termination of his employment) in an amount equal to 1/12th of his then
applicable annual Base Salary immediately prior to his disability. If the
disability insurance policy should begin payment while the Executive is still
being compensated by the Company under the terms of this Agreement, the
Executive will reimburse the Company for all portions of such payments which
cause his total compensation to exceed the amounts otherwise payable to the
Executive under the terms of this Agreement.

          (iii) Medical. Medical insurance protection for the Executive and his
family at least as favorable to the Executive and his family as the protection
and plan being made available to them on the date of this Agreement. In
addition, if not covered by insurance, the Company shall provide the Executive
with an annual health checkup.

          (iv) Professional Services Allowance. The Company will pay up to
$2,500 per year for Executive's tax planning and preparation and/or other
financial planning services used by the Executive.

          (v) Automobile. The Company will furnish the Executive, without cost
to him, with a Company-owned or leased automobile of the make and model then
authorized by the Company's policy or provide an allowance for that purpose.


<PAGE>

          (vi) Other. Such other benefits, not duplicative of the foregoing,
which the Board of Directors may now or in the future make available to its
senior executives.

4. Support and Expenses. The Company shall provide the Executive with an office,
staff and other support appropriate for the Chairman of the Board and Chief
Executive Officer of an organization of the stature of the Company, and shall
pay or reimburse the Executive for all reasonable travel and other expenses
incurred by him in connection with the performance of his services under this
Agreement upon presentation of expense statements or vouchers and such other
supporting information as the Company may from time to time reasonably request.

5. Termination by Company After Initial Term. If the Company shall terminate the
employment of Executive after the end of the third year of this Agreement, for a
reason other than "disability" or "cause," as defined in Section 0 hereof, the
Company shall continue to pay the Executive all of his compensation set forth in
Section 0 hereof through the effective date of termination. Thereafter the
Company shall pay to the Executive any compensation and other benefits which
were vested as of the effective date of termination but payable at a later date.
In addition to all of the foregoing, the Company shall pay to the Executive on
the first business day of the month following the effective date of termination
severance pay (herein called "Severance Pay") in a lump sum equal to 1/12th of
his then applicable annual Base Salary.

6. Termination by Company Prior to End of Initial Term. If the Company shall
terminate the employment of Executive prior to the end of the third year of this
Agreement, for a reason other than "disability" or "cause" as defined in Section
0 hereof, or if the Executive shall terminate his employment after the Company
has committed a material breach of this Agreement, then the Company shall pay to
the Executive as they become due, amounts otherwise payable to the Executive if
he had remained in the employment of the Company until the end of the third year
of this Agreement. In addition, the Company shall (i) forthwith pay Severance
Pay computed in accordance with Section 0 hereof, (ii) thereafter pay all
amounts of compensation and benefits which were vested on the date of
termination but not payable until a later date, including amounts payable under
Section 0(0) hereof, and (iii) comply with Section 0 hereof.

7. Termination for Disability or Cause. The Company may terminate the
Executive's employment due to "disability" if the Board of Directors shall
determine in good faith, that, by reason of physical or mental illness or other
condition continuing for more than one hundred and twenty (120) consecutive days
or for shorter periods aggregating more than one hundred and twenty (120) days
in any period of twelve (12) months (excluding in each case days on which on the
Executive was on vacation), the Executive has been substantially unable to
render services of the character contemplated by this Agreement. The Company may
terminate the Executive's employment for "cause" if the Board of Directors shall
determine in good faith that there shall have been a willful breach by the
Executive in a material manner of his duty of loyalty to the Company. If the
Company shall terminate the employment of Executive for disability or for cause
at any time, the Company shall have no further obligation hereunder except for
payment of Base Salary for services previously rendered, payment or provision of
other compensation or benefits previously vested, and the duty set forth in
Section 0 hereof.

8. Voluntary Termination. If prior to breach of this Agreement by the Company,
the Executive shall resign as an employee during the term of his employment, the
Company shall have no further obligation hereunder except for payment of Base
Salary for services previously rendered, payment or provision of other
compensation or benefits previously vested, and the duty set forth in Section 0
hereof.

9. Insurance after Termination. Except in case of termination voluntarily by the
Executive, or termination for Cause, the Company shall continue coverage of the
Executive and his family under the Company's group life, health and disability
insurance plans for a period of one year following termination. If such plans do
not continue to protect the Executive after termination of employment, the
Company will use its best efforts upon termination of the Executive's employment
for any reason other than death to arrange for transfer from a Company plan to
the Executive (to be carried, except in case of termination for Cause, at the
Company's expense for a period of one year and thereafter at his own expense)
any life, health and disability insurance protection which may be so
transferred.

10. Covenant Not to Compete. The Executive covenants and agrees that, from the
date hereof and until (i) thirty-six months following resignation by the
Executive pursuant to Section 0 hereof, or (ii) in the case of any other
termination of Executive's employment, six months following the date upon which
the final payment of amounts payable to the Executive by the Company by reason
of such termination becomes due, he shall not, either directly or indirectly,
(a) engage in or conduct any business competitive with the Company's business,
whether individually or as an employee, agent, officer, director, owner,
consultant or otherwise, without the prior written consent of the Board of
Directors of the Company, or (b) induce or attempt to induce any existing or
future 


                                       2
<PAGE>

employee or consultant of the Company or any of its Affiliates to leave
such employment.

11. Litigation. If litigation shall be brought by either party to enforce or
interpret any provision contained herein and such party (the "prevailing party")
shall prevail on any issue contested in such litigation either through
settlement or judgment in favor of the prevailing party, the other party shall
reimburse the prevailing party for reasonable attorneys' fees and disbursements
incurred by the prevailing party in such litigation, and shall pay prejudgment
interest on any money judgment obtained by the prevailing party calculated at
the rate in effect from time to time designated by the Company's principal bank
as its prime rate from the date of the breach by such other party under this
Agreement. 

12. Provisions Becoming Effective upon Change in Control. Beginning on the date
of a Change of Control (as defined below), this Section 0 shall govern
Executive's employment and compensation by the Company and the other matters
referred to herein, and any other employment or severance agreement, arrangement
or policy otherwise applicable to the Executive, including, without limitation,
Sections 0 through 0, shall be superseded by this Section.

(a) Definitions. As used in this Section 0, the following terms shall have the
meanings indicated below.

          (i) "Change of Control" means a change of control of the Company of a
nature that would be required to be reported in response to Item 6(e) of
Schedule 14A of Regulation 14A (or in response to any similar item on any
similar schedule or form) promulgated under the Securities Exchange Act of 1934
(the "Act"), whether or not the Company is then subject to such reporting
requirement; provided, however, that, without limitation, such a Change of
Control shall be deemed to have occurred if:

               (A) any person or group (as such terms are used in connection
with Sections 13(d) and 14(d) of the Act) becomes the "beneficial owner" (as
defined in Rule 13d-3 and 13d-5 under the Act), directly or indirectly, of
securities of the Company representing 35% or more of the combined voting power
of the Company's then outstanding securities;

               (B) the Company is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board of Directors in office immediately prior to such
transaction or event constitute less than a majority of the Board of Directors
thereafter; or

               (C) during any period of twenty-four consecutive months,
individuals who at the beginning of such period constituted the Board of
Directors (including for this purpose any new director whose election or
nomination for election by the Company's stockholders was approved by a vote of
at least two-thirds of the directors then still in office who were directors at
the beginning of such period) cease for any reason to constitute at least a
majority of the Board of Directors. Notwithstanding the foregoing provisions of
this Section 0((0))((0)), a "Change of Control" will not be deemed to have
occurred solely because of the acquisition of securities of the Company (or any
reporting requirement under the Act relating thereto) by an employee benefit
plan maintained by the Company for its employees.

          (ii) "Term of Post-Takeover Employment" means the period beginning on
the date of a "Change of Control" and ending on the earliest of:

               (A) Executive's 65th birthday,

               (B) Executive's death,

               (C) the date on which this Agreement terminates in accordance
with Section 0((0)), and

               (D) the date on which all rights and obligations of the parties
hereto have been satisfied in accordance with the terms of this Agreement.
Neither the expiration of the Term of Post-Takeover Employment nor the
termination of this Agreement will relieve the Company of the obligation to
provide Executive, in accordance with the terms hereof, the payments, benefits
and coverage to which he has become entitled under this Agreement.

(b) Either the Company or Executive may, by giving 60 days' written notice to
the other party, terminate the Agreement as of the third, or any subsequent,
anniversary of the Change of Control.

(c) Termination of Employment.

          (i) In the event Executive's employment is terminated by the Company
during the Term of Post-Takeover Employment for any reason other than "Cause"
(as defined in Section 0((0))((0))) the Company will pay Executive:

               (A) a lump sum cash payment, payable within 30 days of his
termination, equal to 


                                       3
<PAGE>

300% of the sum of:

                    (1) Executive's highest annual base salary in effect at any
time prior to his termination, plus

                    (2) the highest aggregate amount included by the Company on
his Form W-2 for fringe benefits provided in any of the three calendar years
prior to his termination, plus

                    (3) his highest bonus for any of the three full fiscal years
of the Company immediately preceding his termination; plus

               (B) a lump sum cash payment, payable within 30 days of his
termination, equal to 300% of the employer contribution made for his benefit
under the Company's 401(k) plan for the last fiscal year of the Company ending
prior to the Change of Control.

          (ii) In the event of a termination described in Section 0((0))((0)),
Executive, together with his dependents and beneficiaries, will continue
following his termination to participate fully in accordance with Section 0((0))
in all life insurance plans, accident and health plans and other welfare plans,
maintained or sponsored by the Company immediately prior to the Change of
Control, or receive substantially equivalent coverage (or the full value thereof
in cash) from the Company, until the later of

               (A) the end of Executive's Term of Post-Takeover Employment or

               (B) the first anniversary of his termination.

The period of time between such a termination and the next following anniversary
of the Change of Control will be counted as service with the Company for
purposes of any benefit plan of the Company in which Executive is participating
at the time of the termination.

          (iii) In the event of a termination described in 0((0)), Executive
will become immediately entitled to exercise any and all stock options
previously granted to him by the Company notwithstanding any provision to the
contrary of the option or any plan under which it was granted.

          (iv) Upon the occurrence of any breach by the Company of this
Agreement within the meaning of Section 0((0))((0)), Executive may give the
Company written notice of his intention to resign effective the 30th day
following the date of such notice. If the Company does not fully remedy such
breach within 15 days of the date of such notice, Executive's resignation will
become effective on such 30th day. If Executive resigns in accordance with this
Section during the Term of Post-Takeover Employment, his employment will be
deemed to have been terminated by the Company for reasons other than Cause (and
he will be deemed to have offered to continue to provide services to the
Company), and he will be entitled to all the payments and rights and benefits
described in Sections 0((0))((0)), 0((0))((0)) and 0((0))((0)) provided
that such payments and rights and benefits will in no event be less than they
would have been had such termination taken place on the date that the Company
first breached this Agreement.

          (v) The following events are breaches by the Company of this Agreement
within the meaning of this Section 0((0))((0)):

               (A) any reduction of, or failure to pay, Executive's salary or
bonus as described in Sections 0((0)) or 0((0));

               (B) any failure to provide the benefits required by 0((0));

               (C) assignment to Executive of any duties inconsistent in any
respect with his position (including status, offices and titles), authority,
duties or responsibilities as contemplated by Section 0, or any other action by
the Company which results in a diminution of such position, authority, duties or
responsibilities;

               (D) failure after a Change of Control to comply with and satisfy
Section 0((0))((0)) or 0((0))((0));

               (E) relocation of the Company's principal executive offices, or
any event that causes Executive to have his principal place of work changed, to
any location outside the area where its corporate headquarters are located at
the time of the Change of Control;

               (F) any requirement by the Company that Executive travel away
from his office in the course of his duties significantly more than the number
of consecutive days or aggregate days in any calendar year than was required of
him prior to the Change of Control; and

               (G) without limiting the generality or effect of the foregoing,
any other material breach of this Agreement by the Company or any successor
thereto or transferee of substantially all the assets thereof.

          (vi) If Executive is dismissed by the Company for Cause, he will not
be entitled to payments, 


                                       4
<PAGE>

benefits or acceleration of exercisability of options provided under Sections
0((0))((0)), 0((0))((0)) or 0((0))((0)). "Cause" means only the willful
commission by Executive of theft, embezzlement or other serious and substantial
crimes against the Company. For purposes of this definition, no act or omission
shall be considered to have been "willful" unless it was not in good faith and
Executive knew at the time that the act or omission was not in the best interest
of the Company.

          (vii) If Executive's employment is alleged to be terminated for Cause
or if Executive's right to resign under Section 0((0))((0)) is disputed,
Executive may initiate binding arbitration in Suffolk County, New York, before
the American Arbitration Association by serving a notice to arbitrate upon the
Company or, at Executive's election, institute judicial proceedings, in either
case within 90 days of the effective date of his termination or, if later, his
receipt of notice of termination, or such longer period as may be reasonably
necessary for Executive to take such action if illness or incapacity should
impair his taking such action within the 90-day period. The Company agrees

               (A) to pay the costs and expenses (including Executive's counsel
fees), and

               (B) to pay interest to Executive on any amounts ultimately found
to be due to Executive hereunder during any period of time that such amounts are
withheld pending arbitration and/or judicial proceedings. Such interest will be
at a rate of 2% over the base rate most recently announced by the Company's
principle bank prior to the commencement of the arbitration.

          (viii) Termination of employment due to the death or total and
permanent disability of Executive will not be considered a termination for
purposes of this Section.

          (ix) If Executive dies following a termination of employment which
entitled him to benefits under this Section 0((0)) but prior to receipt of all
such benefits:

               (A) his beneficiary (as designated to the Company in writing) or,
if none, his estate, will be entitled to receive all unpaid amounts due
hereunder; and

               (B) his beneficiary or estate will be entitled to exercise
options in accordance with Section 0((0))((0)) and the terms of the options.

(d) No Obligation to Mitigate. There shall be no requirement on the Executive's
part to seek other employment or otherwise mitigate in order to be entitled to
the full amount of any payments or benefits hereunder.

(e) Limitation.

          (i) Notwithstanding any other provision of this Agreement, and except
as provided in Section 0((0))((0)), the payments or benefits to which Executive
will be entitled under Section 0((0)) of this Agreement will be reduced to the
extent necessary so that Executive will not be liable for the federal excise tax
levied on certain "excess parachute payments" under section 4999 of the Code.

          (ii) The limitation of Section 0((0))((0)) will not apply if:

               (A) the difference between

                    (1) the present value of all payments to which Executive is
entitled under Section 0((0)) of this Agreement determined without regard to
Section 0((0))((0)), less

                    (2) the present value of all federal, state, and other
income and excise taxes for which Executive is liable as a result of such
payments; exceeds

               (B) the difference between

                    (1) the present value of all payments to which Executive is
entitled under Section 0((0)) of this Agreement calculated as if the limitation
of Section 0((0))((0)) applies, less

                    (2) the present value of all federal, state, and other
income and excise taxes for which Executive is liable as a result of such
reduced payments. Present values will be determined using the interest rate
specified in section 280G of the Code and will be the present values as of the
date on which Executive's employment terminates (unless it is necessary to use a
different date in order to avoid adverse consequences under section 280G).

          (iii) Whether payments to the Executive are to be reduced pursuant to
Section 0((0))((0)), and the extent to which they are to be so reduced, will be
determined by the Executive. Executive may, at the expense of the Company, hire
an accounting firm, law firm or employment consulting firm selected by Executive
to assist him in such determination.

          (iv) If a reduction is made pursuant to Section 0((0))((0)), Executive
will have the right to determine which payments and benefits will be reduced.


                                       5
<PAGE>

(f) Expenses.

          (i) It is the intent of the Company that the Executive not be required
to incur any expenses associated with the enforcement of his rights under this
Agreement by legal action or arbitration proceeding because the cost and expense
thereof would substantially detract from the benefits intended to be extended to
the Executive hereunder. Accordingly, if Executive determines in good faith that
the Company has failed to comply with any of its obligations under this
Agreement, or if the Company or any other person takes any action to declare
this Agreement void or unenforceable, or institutes any legal action or
arbitration proceeding designed to deny Executive, or to recover from him, the
benefits intended to be provided hereunder, or in the event of actions
instituted as contemplated by Section 0((0))((0)), the Company irrevocably
authorizes Executive from time to time to retain counsel of his choice, at the
expense of the Company as hereafter provided, to represent Executive in
connection with any and all actions and proceedings, whether by or against the
Company or any director, officer, stockholder or other person affiliated with
the Company, which may adversely affect Executive's rights under this Agreement.
In addition, notwithstanding any existing or prior attorney-client relationship
between the Company and such counsel, the Company irrevocably consents to
Executive's entering into an attorney-client relationship with such counsel and
agrees that a confidential relationship shall exist between Executive and such
counsel. Without limiting the effect of Section 0((0))((0)) or of the
foregoing provisions of this Section 0((0))((0)), the Company shall pay or
cause to be paid and shall be solely responsible for any and all attorneys' and
related fees and expenses incurred by Executive as a result of the Company's
failure to perform under this Agreement.

          (ii) Without limiting the effect of Section 0((0))((0)), in order to
ensure the benefits intended to be provided to the Executive under such Section,
the Company will, if a Change of Control becomes likely or occurs, use
reasonable efforts to obtain an irrevocable $1,000,000 letter of credit issued
by a bank having combined capital and surplus in excess of $100,000,000, or
alternatively to place that amount in escrow or trust with such a bank, to
provide a fund for the benefit of Executive and other employees of the Company
with similar agreements with respect to enforcement of their rights under their
agreements, all on such terms as the Company shall consider appropriate when it
obtains such a letter of credit or establishes such a fund. 

(g) Merger or Acquisition.

          (i) If the Company is at any time before or after a Change of Control
merged with or consolidated into or with any other corporation or other entity
(whether or not the Company is the surviving entity), or if substantially all of
the assets of the Company are transferred to another corporation or other
entity, the corporation or other entity resulting from such merger or
consolidation, or the acquirer of such assets, shall (by agreement in form and
substance satisfactory to Executive) expressly assume the obligations of the
Company under this Agreement. In any event, however, the provisions of this
Agreement shall be binding upon and inure to the benefit of the corporation or
other entity resulting from such merger or consolidation or the acquirer of such
assets, and this Section 0((0)) will apply in the event of any subsequent
merger or consolidation or transfer of assets.

          (ii) In the event of any merger, consolidation or sale of assets
described above, nothing contained in this Agreement will detract from or
otherwise limit Executive's right to or privilege of participation in any stock
option or purchase plan or any bonus, profit sharing pension group insurance
hospitalization or other incentive or benefit plan or arrangement which may be
or become applicable to executives of the corporation resulting from such merger
or consolidation or the corporation acquiring such assets of the Company.

          (iii) In the event of any merger, consolidation or sale of assets
described above, references to the Company in this Agreement shall unless the
context suggests otherwise be deemed to include the entity resulting from such
merger or consolidation or the acquirer of such assets of the Company. 

13. Entire Agreement; Amendments. This Agreement contains the entire agreement
and understanding of the parties relating to the subject matter hereof and
supersedes all prior discussions, agreements and understandings of every nature
between them. This Agreement may not be changed or modified, except by an
agreement in writing signed by all of the parties hereto.

     By this Lease Landlord leases to Tenant and Tenant leases from Landlord the
Building as set forth and described on the Reference Page (the "Premises"). The
Reference Page, including all terms defined thereon, is incorporated as part of
this Lease.

1. USE AND RESTRICTIONS ON USE.

     1.1 The Premises are to be used solely for the purposes stated on the
Reference Page. Tenant shall not do or permit anything to be done in or about
the Premises which will in any way obstruct or interfere with the rights of
other tenants or occupants of the Building or injure, annoy, or disturb them or
allow the Premises to be used for any improper, immoral, unlawful, or
objectionable purpose. Tenant shall not do, permit or suffer in, on, or about
the Premises the sale of any alcoholic liquor without the written consent of
Landlord first obtained, or the commission of any waste. Tenant shall comply
with all governmental laws, ordinances and regulations applicable to the use of
the Premises and its occupancy and shall promptly comply with all governmental
orders and directions for the correction, prevention and abatement of any
violations in or upon, or in connection with, the Premises, all at Tenant's sole
expense. Tenant shall not do or permit anything to be done on or about the
Premises or bring or keep anything into the Premises which will in any way
increase the rate of, invalidate or prevent the procuring of any insurance
protecting against loss or damage to the Building or any of its contents by fire
or other casualty or against liability for damage to property or injury to
persons in or about the Building or any part thereof.

     1.2 Tenant shall not, and shall not direct, suffer or permit any of its
agents, contractors, employees, licensees or invitees to at any time handle,
use, manufacture, store or dispose of in or about the Premises or the Building
any (collectively "Hazardous Materials") flammables, explosives, radioactive
materials, hazardous wastes or materials, toxic wastes or materials, or other
similar substances, petroleum products or derivatives or any substance subject
to regulation by or under any federal, state and local laws and ordinances
relating to the protection of the environment or the keeping, use or disposition
of environmentally hazardous materials, substances, or wastes, presently in
effect or hereafter adopted, all amendments to any of them, and all rules and
regulations issued pursuant to any of such laws or ordinances (collectively
"Environmental Laws"), nor shall Tenant suffer or permit any Hazardous Materials
to be used in any manner not fully in compliance with all Environmental Laws, in
the Premises or the Building and appurtenant land or allow the environment to
become contaminated with any Hazardous Materials. Notwithstanding the foregoing,
and subject to Landlord's prior consent, Tenant may handle, store, use or
dispose of products containing small quantities of Hazardous Materials (such as
aerosol cans containing insecticides, toner for copiers, paints, paint remover
and the like) to the extent customary and necessary for the use of the Premises
for general office purposes, provided that Tenant shall always handle, store,
use, and dispose of any such Hazardous Materials in a safe and lawful manner and
never allow such Hazardous Materials to contaminate the Premises, Building and
appurtenant land or the environment. Tenant shall protect, Defend, indemnify and
hold each and all of the Landlord Entities (as defined in Article 28) harmless
from and against any and all loss, Claims, liability or costs (including court
costs and attorney 5 fees) incurred by reason of any actual or asserted failure
of Tenant to fully comply with all applicable Environmental Laws, or the
presence, handling, use or disposition in or from the Premises of any Hazardous
Materials (even though permissible under all applicable Environmental Laws or
the provisions of this Lease), or by reason of any actual or asserted failure of
Tenant to keep, observe, or perform any provision of this Section 1.2. 

                                                                       See Rider

2. TERM.

     2.1 The Term of this Lease shall begin on the date ("Commencement Date")
which shall be the later of the Scheduled Commencement Date as shown on the
Reference Page and the date that Landlord shall tender possession of the
Premises to Tenant. Landlord shall tender possession of the Premises with all
the work, if any, to be performed by Landlord pursuant to Exhibit B to this
Lease substantially completed. Tenant shall deliver a punch list 

<PAGE>

of items not completed within 30 days after Landlord tenders possession of the
Premises and Landlord agrees to proceed with due diligence to perform its
obligations regarding such items. Landlord and Tenant shall execute a memorandum
setting forth the actual Commencement Date and Termination Date.

     2.2 Tenant agrees that in the event of the inability of Landlord to deliver
possession of the Premises on the Scheduled Commencement Date. Landlord shall
not be liable for any damage resulting from such inability. but Tenant shall not
be liable for any rent until the time when Landlord can. after notice to Tenant,
deliver possession of the Premises to Tenant. No such failure to give possession
on the Scheduled Commencement Date shall affect the other obligations of Tenant
under this Lease, except that if Landlord is unable to deliver possession of the
Premises within one hundred twenty (120) days of the Scheduled Commencement Date
(other than as a result of strikes, shortages of materials or similar matters
beyond the reasonable control of Landlord and Tenant is notified by Landlord in
writing as to such delay). Tenant shall have the option to terminate this Lease
unless said delay is as a result of: (a) Tenant's failure to agree to plans and
specifications; (b) Tenant's request for materials, finishes or installations
other than Landlord's standard except those, if any, that Landlord shall have
expressly agreed to furnish without extension of time agreed by Landlord; (c)
Tenant's change in any plans or specifications; or, (d) performance or
completion by a party employed by Tenant. If any delay is the result of any of
the foregoing, the Commencement Date and the payment of rent under this Lease
shall be accelerated by the number of days of such delay.

     2.3 In the event Landlord shall permit Tenant to occupy the Premises prior
to the Commencement Date, such occupancy shall be subject to all the provisions
of this Lease. Said early possession shall not advance the Termination Date.

3. RENT.

     3.1 Tenant agrees to pay to Landlord the Annual Rent in effect from time to
time by paying the Monthly Installment of Rent then in effect on or before the
first day of each full calendar month during the Term, except that the first
month's rent shall be paid upon the execution of this Lease. The Monthly
Installment of Rent in effect at any time shall be one-twelfth of the Annual
Rent in effect at such time. Rent for any period during the Term which is less
than a full month shall be a prorated portion of the Monthly Installment of Rent
based upon a thirty (30) day month. Said rent shall be paid to Landlord, without
deduction or offset and without notice or demand, at the Landlord's address, as
set forth on the Reference Page, or to such other person or at such other place
as Landlord may from time to time designate in writing.

     3.2 Tenant recognizes that late payment of any rent or other sum due under
this Lease will result in administrative expense to Landlord, the extent of
which additional expense is extremely difficult and economically impractical to
ascertain. Tenant therefore agrees that if rent or any other sum is not paid
when due and payable pursuant to this Lease, a late charge shall be imposed in
an amount equal to the greater of: (a) Fifty Dollars ($50.00), or (b) a sum
equal to five percent (5%) per month of the unpaid rent or other payment. The
amount of the late charge to be paid by Tenant shall be reassessed and added to
Tenant's obligation for each successive monthly period until paid. The
provisions of this Section 3.2 in no way relieve Tenant of the obligation to pay
rent or other payments on or before the date on which they are due, nor do the
terms of this Section 3.2 in any way affect Landlord's remedies pursuant to
Article 18 in the event said rent or other payment is unpaid after date due.

4. TAXES.

     4.1 Tenant shall pay as additional rent all Taxes incurred on the Building
during the Term. Taxes shall be defined as real estate taxes and any other
taxes, charges and assessments which are levied with respect to the Building or
the land appurtenant to the Building, or with respect to any improvements,
fixtures and equipment or other property of Landlord, real or personal, located
in the Building and used in connection with the operation of the Building and
said land, any payments to any ground lessor in reimbursement of tax payments


<PAGE>

made by such lessor; and if a reduction, rebate or refund is obtained, all fees,
expenses and costs incurred by Landlord in investigating, protesting, contesting
or in any way seeking to reduce or avoid increase in any assessments, levies or
the lax rate pertaining to any Taxes to be paid by Landlord in any Lease Year.
Taxes shall not include any corporate franchise, or estate, inheritance or net
income tax, or tax imposed upon any transfer by Landlord of its interest in this
Lease or the Building.

     4.2 Prior to the actual determination thereof, Landlord may from time to
time estimate Tenant's liability for Taxes under Section 4.1, Article 6 and
Article 27 for the lease year or portion thereof. Landlord will give Tenant
written notification of the amount of such estimate and Tenant agrees that it
will pay, by increase of its Monthly Installments of Rent due in such lease
year, additional rent in the amount of such estimate. Any such increased rate of
Monthly Installments of Rent pursuant to this Section 4.2 shall remain in effect
until further written notification to Tenant pursuant hereto. Landlord will
provide copies of all tax bills.

     4.3 When the above mentioned actual determination of Tenant's liability for
Taxes is made in any lease year and when Tenant is so notified in writing, then:

          4.3.1 If the total additional rent Tenant actually paid pursuant to
Section 4.2 is less than Tenant's liability for Taxes, then Tenant shall pay to
Landlord as additional rent in one lump sum within thirty (30) days of receipt
of Landlord's bill therefor such deficiency; and

          4.3.2 If the total additional rent Tenant actually paid pursuant to
Section 4.2 is more than Tenant's liability for Taxes, then Landlord shall
credit the difference against the then next due payments to be made by Tenant
under this Article 4.

     4.4 If the Commencement Date is other than January 1 or if the Termination
Date is other than December 31, Tenant's liability for Taxes for the year in
which said Date occurs shall be prorated based upon a three hundred sixty five
(365) day year.

     4.5 Even though the Term has expired and Tenant has vacated the premises,
when the final determination is made of Tenant's liability for Taxes for the
year in which the Lease terminated. Tenant shall pay any difference due over the
estimated Taxes paid; and conversely any overpayment, less any amounts due
Landlord under this Lease, shall be rebated to Tenant.

5. SECURITY DEPOSIT.

Tenant shall deposit the Security Deposit with Landlord upon the execution of
this Lease. Said sum shall be held by Landlord as security for the faithful
performance by Tenant of all the terms, covenants and conditions of this Lease
to be kept and performed by Tenant and not as an advance rental deposit or as a
measure of Landlord's damage in case of Tenant's default. If Tenant defaults
with respect to any provision of this Lease. Landlord may use any part of the
Security Deposit for the payment of any rent or any other sum in default, or for
the payment of any amount which Landlord may spend or become obligated to spend
by reason of Tenant's default, or to compensate Landlord for any other loss or
damage which Landlord may suffer by reason of Tenant's default. If any portion
is so used. Tenant shall within five (5) days after written demand therefor,
deposit with Landlord an amount sufficient to restore the Security Deposit to
its original amount and Tenant's failure to do so shall be a material breach of
this Lease. Except to such extent, if any, as shall be required by law, Landlord
shall not be required to keep the Security Deposit separate from its general
funds, and Tenant shall not be entitled to interest on such deposit. If Tenant
shall fully and faithfully perform every provision of this Lease to be performed
by it, the Security Deposit or any balance thereof shall be returned to Tenant
at such time after termination of this Lease when Landlord shall have determined
that all of Tenant's obligations under this Lease have been fulfilled.

                                                                       See Rider

this Lease. Tenant shall not make or suffer to be made any alterations.

applying for such consent, Tenant shall, if requested by Landlord, furnish
complete plans and specifications for such alterations, additions and
improvements. See Rider

     6.2 In the event Landlord consents to the making of any such alteration,
addition or improvement by Tenant, the same shall be made using Landlord's
contractor (unless Landlord agrees otherwise) at Tenant's sole cost and expense.
If Tenant shall employ any Contractor other than Landlord's Contractor and such
other Contractor or any Subcontractor of such other Contractor shall employ any
non-union labor or supplier, Tenant shall be responsible for and hold Landlord
harmless from any and all delays, damages and extra costs suffered by Landlord
as a result of any dispute with any labor unions concerning the wage, hours,
terms or conditions of the employment of any such labor. In any event Landlord
may charge Tenant a reasonable charge to cover its overhead as it relates to
such proposed work.

     6.3 All alterations. additions or improvements proposed by Tenant shall be
constructed in accordance with all government laws, ordinances, rules and
regulations and Tenant shall. prior to construction, provide the additional
insurance required under Article II in such case, and also all such assurances
to Landlord, including but not limited to, waivers of lien, surety company
performance bonds Landlord shall require to assure payment of the costs thereof
and to protect Landlord and the Building and appurtenant land against any loss
from any mechanic's, materialmen's or other liens.

     6.4 All alterations, additions, and improvements in, on, or to the Premises
made or installed by Tenant, including carpeting, shall be and remain the
property of Tenant during the Term but, excepting furniture, furnishings,
movable partitions of less than full height from floor to ceiling and other
trade fixtures, shall become a part of the realty and belong to Landlord without
compensation to Tenant upon the expiration or sooner termination of the Term, at
which time title shall pass to Landlord under this Lease as by a bill of sale,
unless Landlord elects otherwise. Upon such election by Landlord, Tenant shall
upon demand by Landlord, at Tenant's sole cost and expense, forthwith and with
all due diligence remove any such alterations, additions or improvements which
are designated by Landlord to be removed, and Tenant shall forthwith and with
all due diligence, at its sole cost and expense, repair and restore the Premises
to their original condition, reasonable wear and tear and damage by fire or
other casualty excepted.

     6.5 Tenant shall pay in addition to any sums due pursuant to Article 4, any
increase in real estate taxes attributable to any such alteration, addition or
improvement for so long, during the Term, as such increase is ascertainable, at
Landlord's election said sums shall be paid in the same way as sums due under
Article 4.

7. REPAIR.

     7.1 Landlord shall have no obligation to alter, remodel, improve, repair,
decorate or paint the Premises, except as specified in Exhibit B if attached t
this Lease. By taking possession of the Premises, Tenant accepts them as being
in good order, condition and repair and in the condition in which Landlord is
obligated to deliver them. Tenant acknowledges that it is taking the Premises
"AS IS." It is hereby understood and agreed that no representations respecting
the condition of the Premises or the Building have been made by Landlord to
Tenant, except as specifically set forth in this Lease. Landlord shall not be
liable for any failure to make any repairs or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. See Rider

     7.2 Except for Landlord's obligations under Section 7.1, Tenant shall at
its own cost and expense keep and maintain all parts of the Premises in good

Premises from deterioration due to ordinary wear and from falling temporarily
out of repair, and upon termination of this Lease in any way Tenant will yield
up the Premises to Landlord in good condition and repair, loss by fire or other
casualty excepted (but not excepting any damage to glass).

     7.3 Except as provided in Article 21, there shall be no abatement of rent
and no liability of Landlord by reason of any injury to or interference with
Tenant's business arising from the making of any repairs, alterations or
improvements in or to any portion of the Building or the Premises or to

use reasonable efforts to minimize interruption of Tenant's business during any
such activities.

leasehold interest in the Premises free from an liens arising out of any
services, work or materials performed, furnished, or contracted for by Tenant,

thirty (30) days following the imposition of any such lien, either cause the
same to be released of record or provide Landlord with insurance against the
same issued by a major title insurance company or such other protection against
the same as Landlord shall accept, Landlord shall have the right to cause the
same to be released by such means as it shall deem proper, including payment of
the claim giving rise to such lien. All such sums paid by Landlord and all
expenses incurred by it in connection therewith shall be considered additional
rent and shall be payable to it by Tenant on demand.

9. ASSIGNMENT AND SUBLETTING.

     9.1 Tenant shall not have the right to assign or pledge this Lease or to
sublet the whole or any part of the Premises whether voluntarily or by operation
of law, or permit the use or occupancy of the Premises by anyone other than
Tenant, and shall not make, suffer or permit such assignment, subleasing or
occupancy without the prior written consent of Landlord, and said restrictions
shall be binding upon any and all assignees of the Lease and subtenants of the
Premises. In the event Tenant desires to sublet, or permit such occupancy of,
the Premises, or any portion thereof, or assign this Lease. Tenant shall give
written notice thereof to Landlord at least ninety (90) days but no more than
one hundred eighty (180) days prior to the proposed commencement date of such
subletting or assignment, which notice shall set forth the name of the proposed
subtenant or assignee, the relevant terms of any sublease or assignment and
copies of financial reports and other relevant financial reports and other
relevant financial information of the proposed subtenant or assignee.

     9.2 Notwithstanding any assignment or subletting, permitted or otherwise,
Tenant shall at all times remain directly, primarily and fully responsible and
liable for the payment of the rent specified in this Lease and for compliance
with all of its other obligations under the terms, provisions and covenants of
this Lease. Upon the occurrence of an Event of Default, if the Premises or any
part of them are then assigned or sublet. Landlord, in addition to any other
remedies provided in this Lease or provided by law, may, at its option, collect
directly from such assignee or subtenant all rents due and becoming due to
Tenant under such assignment or sublease and apply such rent against any sums
due to Landlord from Tenant under this Lease, and no such collection shall be
construed to constitute a novation or release of Tenant from the further
performance of Tenant's obligations under this Lease.

     9.3 In addition to Landlord's right to approve of any subtenant or
assignee, Landlord shall have the option, in its sole discretion, in the event
of any proposed subletting of more than 50% of the Premises or assignment of the
Lease to terminate this Lease, or in the case of a proposed subletting of less
than he entire Premises, to recapture the portion of the Premises to be sublet,
as of the date the

<PAGE>

subletting or assignment is to be effective. The option shall be exercised, if
it all, by Landlord giving Tenant written notice given by Landlord to Tenant
within sixty (60) days following Landlord's receipt of Tenant's written notice
as required above. If this Lease shall be terminated with respect to the entire
Premises pursuant to this Section, the Term of this Lease shall end on the date
stated in Tenant's notice as the effective date, of the sublease or assignment
as if that date had been originally fixed in this Lease for the expiration of
this Term. If Landlord recaptures under this Section only a portion of the
Premises, the rent to be paid from time to time during the unexpired Term shall
abate proportionately based on the proportion by which the approximate square
footage of the remaining portion of the Premises shall be less than that of the
Premises as of the date immediately prior to such recapture. Tenant shall at
Tenant's own cost and expense, discharge in full any outstanding commission
obligation on the part of Landlord with respect to this Lease, and any
commissions which may be due and owing as a result of any proposed assignment or
subletting, whether or not the Premises are recaptured pursuant to this Section
9.3 and rented by Landlord to the proposed tenant or any other tenant.

     9.4 In the event that Tenant sells, sublets, assigns or transfers this
Lease, Tenant shall pay to Landlord as additional rent an amount equal to fifty
percent (50%) of any Increased Rent (as defined below) when and as such
Increased Rent is received by Tenant. As used in this Section, "Increased Rent"
shall mean the excess of (i) all rent and other consideration which Tenant is
entitled to receive by reason of any sale, sublease, assignment or other
transfer of this Lease, over (ii) the rent otherwise payable by Tenant under
this Lease at such time. For purposes of the foregoing, any consideration
received by Tenant in form other than cash shall be valued at its fair market
value as determined by Landlord in good faith.

     9.5 Notwithstanding any other provision hereof, Tenant shall have no right
to make (and Landlord shall have the absolute right to refuse consent to) any
assignment of this Lease or sublease of any portion of the Premises if at the
time of either Tenant's notice of the proposed assignment or sublease or the
proposed commencement date thereof, there shall exist any uncured default of
Tenant or matter which will become a default of Tenant with passage of time
unless cured; or if the proposed assignee or sublessee is an entity: (a) with
which Landlord is already in negotiation as evidenced by the Issuance of a
written proposal; (b) is already an occupant of the Building unless Landlord is
unable to provide the amount of space required by such occupant; (c) is a
governmental agency; (d) is incompatible with the character of occupancy of the
Building; or (e) would subject the Premises to a use which would: (i) involve
increased personnel or wear upon the Building; (ii) violate any exclusive right
granted to another tenant of the Building; (iii) require any addition to or
modification of the Premises or the Building in order to comply with building
code or other governmental requirements; or, (iv) involves a violation of
Section 1.2. Tenant expressly agrees that Landlord shall have the absolute right
to refuse consent to any such assignment or sublease and that for the purposes
or any statutory or other requirement of reasonableness on the part of Landlord
such refusal shall be reasonable.

     9.6 Upon any request to assign, or sublet, Tenant will pay to Landlord the
Assignment/Subletting Fee plus, on demand, a sum equal to all of Landlord's1
actual and reasonable costs, including reasonable attorney's fees, incurred in
investigating and considering any proposed or purported assignment or pledge of
this Lease or sublease of any of the Premises, regardless of whether Landlord
shall consent to, refuse consent, or determine that Landlord's consent is not
required for, such assignment, pledge or sublease. Any purported sale,
assignment, mortgage, transfer of this Lease or sublettIng which does not comply
with the provislons of this Article 9 shall be void.

     9.7 If Tenant is a corporation, partnership or trust, any transfer or
transfers of or change or changes within any twelve month period in the number
of the outstanding voting shares of the corporation, the general partnership
interests in the partnership or the identity of the persons or entities
controlling the activities of such partnership or trust resulting in the parsons
or entities owning or controlling a majority or such shares, partnership
interests or activities of such partnership or trust at the beginning of such
period no longer having such ownership or control shall be regarded as
equivalent to an assignment of this Lease to the persons or entities acquiring
such ownership or control and shall be subject to all the provisions of this
Article 9 to the same extent and for all intents and purposes as though such an
assignment.

10. INDEMNIFICATION.

None of the Landlord Entities shall be liable and Tenant hereby waives all
claims against them for any damage to any property or any injury to any person
in or about the Premises by or from any cause whatsoever (including without
limiting the foregoing, rain or water leakage

<PAGE>

character from the roof, windows, walls, basement, pipes, plumbing works or
appliances, the Premises not being in good condition of repair, gas, fire, oil,
electricity or theft), except that landlord will indemnify and hold tenant
harmless from such claims to the extent caused by or arising from the negligence
or willful misconduct of Landlord or its agents, employees or contractors.
Tenant shall protect, indemnify and hold the Landlord Entities harmless from and
against any and all loss, claims, liability or costs (including court costs and
attorney's fees) incurred by reason of (a) any damage to any property (including
but not limited to property of any Landlord Entity) or any injury (including but
not limited to death) to any person occurring in, on or about the Premises to
the extent that such injury or damage shall be caused by or arise from any
actual or alleged act, neglect, fault, or omission by or of Tenant, its agents,
servants, employees, invitees, or visitors to meet any standards imposed by any
duty with respect to the injury or damage; (b) the conduct or management of any
work or thing whatsoever done by the Tenant in or about the Premises or from
transactions of the Tenant concerning the Premises; (c) Tenant's failure to
comply with any and all governmental law, ordinances and regulations applicable
to the condition or use of the Premises or its occupancy, or (d) any breach or
default on the part of Tenant to the performance of any covenant or agreement on
the part of the Tenant to be performed pursuant to this Lease. The provisions of
this Article shall survive the termination of this Lease with respect to any
claims or liability accruing prior to such termination.

expense; (b) name the Landlord and the building management company, if any, as
additional insureds; (c) be issued by an insurance company with a minimum Best's

     11.3 Whenever Tenant shall undertake any alterations, additions or
improvements in, to or about the Premises ("Work") the aforesaid
insurance protection must extend to and include injuries to persons and damage
to property arising in connection with such Work, without limitation including
liability under any applicable structural work act, and such other insurance as
Landlord shall require; and the policies of or certificates evidencing such
insurance must be delivered to Landlord prior to the commencement of any such

mutually waive their respective rights of recovery against each other for any
loss insured by fire, extended coverage, all Risks or other insurance now or

extent of the net insurance proceeds payable under such policies. Each party

plus all Rent Adjustments under Article 4; and, (b) the then market rental value
of the Premises as determined by Landlord assuming a new lease of the Premises
of the then usual duration and other terms, in either case prorated on a daily
basis, and also pay all damages sustained by Landlord by reason of such

effect, such holding over shall constitute renewal of this Lease for a period
from month to month or one year, whichever shall be specified in such notice, in
either case at the Holdover Rate, but if the Landlord does not so elect, no such
renewal shall result notwithstanding acceptance by Landlord of any sums due
hereunder after such termination; and instead, a tenancy at sufferance at the
Holdover Rate shall be deemed to have been created. In any event, no provision
of this Article 14 shall be deemed to waive Landlord's right of reentry or any
other right under this Lease or at law. 

15. SUBORDINATION.

Without the necessity of any additional document being executed by Tenant for
the purpose of effecting a subordination, this Lease shall be subject and
subordinate at all times to ground or underlying leases and to the lien of any
mortgages or deeds of trust now or hereafter placed on, against or affecting the
Building, Landlord's interest or estate in the Building, or any ground or
underlying lease; provided, however, that if the lessor, mortgagee, trustee, or
holder of any such mortgage or deed of trust elects to have Tenant's interest in
this Lease be superior to any such instrument, then, by notice to Tenant, this
Lease shall be deemed superior, whether this Lease was executed before or after
said instrument. Notwithstanding the foregoing, Tenant covenants and agrees to
execute and deliver upon demand such further instruments evidencing such
subordination or superiority of this Lease as may be required by Landlord.

and to alter, improve or repair the Premises and any portion of the Building,
without abatement of rent, and may for that purpose erect, use and maintain
scaffolding, pipes, conduits and other necessary structures and open any wall,
ceiling or floor in and through the Building and Premises where reasonably

Premises shall not be blocked thereby, and further provided that the business of
Tenant shall not be interfered with unreasonably.

     16.2 Except to the extent of Landlord's negligence, Tenant hereby waives
any claim for damages for any injury or inconvenience to or interference with
Tenant's business, any loss of occupancy or quiet enjoyment of the Premises, and
any other loss occasioned by any action of Landlord authorized by this Article

expenses which Landlord may incur in thus effecting compliance with Tenant's
obligations under this Lease.

Landlord may deem proper to open said doors in an emergency to obtain entry to
any portion of the Premises. As to any portion to which access can not be had by
means of a key or keys in Landlord's possession. Landlord is authorized to gain
access by such means as Landlord shall elect and the cost of repairing any
damage occurring in doing so shall be borne by Tenant and paid to Landlord as
additional rent upon demand.

this Lease, whether or not treated as additional rent under this Lease, and such
failure shall continue for a period of five business days after written notice
that such payment was not made when due, but if any such notice shall be given,
for the twelve month period commencing with the date of such notice, the failure
to pay within five business days after due any additional sum of money becoming
due to be paid to Landlord under this Lease during such period shall be an Event

          17.1.2 Tenant shall fail to comply with any term, provision or
covenant of this Lease which is not provided for in another Section of this
Article and shall not cure such failure within thirty (30) days (forthwith, if

thirty (30) days from the date of entry thereof.

     18.1 Except as otherwise provided in Article 19, upon the occurrence of any
of the Events of Default described or referred to in Article 17 and after
expiration of all cure and/or grace periods stated there, Landlord shall have
the option to pursue any one or more of the following remedies without any
notice or demand whatsoever, concurrently or consecutively and not
alternatively:

          18.1.1 Landlord may, at its election, terminate this Lease or
terminate Tenant's right to possession only, without terminating the Lease.

          18.1.2 Upon any termination of this Lease, whether by lapse of time or
otherwise, or upon any termination of Tenant's right to possession without
termination of the Lease, Tenant shall surrender possession and vacate the
Premises immediately, and deliver possession thereof to Landlord, and Tenant

Premises in such event and to repossess Landlord of the Premises as of
Landlord's former estate and to expel or remove Tenant and any others who may be
occupying or be within the Premises and to remove Tenant's signs and other
evidence of tenancy and all other property of Tenant therefrom without being
deemed in any manner guilty of trespass, eviction or forcible entry or detainer,
and without incurring any liability for any damage resulting therefrom, Tenant
waiving any right to claim damages for such reentry and expulsion, and without
relinquishing Landlord's right to rent or any other right given to Landlord
under this Lease or by operation of law.

          18.1.3 Upon any termination of this Lease, whether by lapse of time or
otherwise, Landlord shall be entitled to recover as damages, all rent, including
any amounts treated as additional rent under this Lease, and other sums due and
payable by Tenant on the date of termination, plus as liquidated damages and not
as a penalty, an amount equal to the sum of: (a) an amount equal to the then
present value of the rent reserved in this Lease for the residue of the stated
Term of this Lease including any amounts treated as additional rent under this
Lease and all other sums provided in this Lease to be paid by Tenant, minus the
fair rental value of the Premises for such residue; (b) the value of the time
and expense necessary to obtain a replacement tenant or tenants, and the
estimated expenses described in Section 18.1.4 relating to recovery of the
Premises, preparation for reletting and for reletting itself;


<PAGE>

and (c) the cost of performing any other covenants which would have otherwise
been performed by Tenant.

          18.1.4 Upon any termination of Tenant's right to possession only
without termination of the Lease:

          18.1.4.1 Neither such termination of Tenant's right to possession nor
Landlord's taking and holding possession thereof as provided in Section 18.1.2
shall terminate the Lease or release Tenant, in whole or in part, from any
obligation, including Tenant's obligation to pay the rent, including any amounts
treated as additional rent, under this Lease for the full Term, and if Landlord
so elects Tenant shall pay forthwith to Landlord the sum equal to the entire
amount of the rent, including any amounts treated as additional rent under this
Lease, for the remainder of the Term plus any other sums provided in this Lease
to be paid by Tenant for the remainder of the Term.

          18.1.4.2 Landlord shall use commercially reasonable efforts to relet
the Premises or any part thereof for such rent and upon such terms as Landlord,
in its sole discretion, shall determine (including the right to relet the
premises for a greater or lesser term than that remaining under this Lease, the
right to relet the Premises as a part of a larger area, and the right to change
the character or use made of the Premises). In connection with or in preparation
for any reletting, Landlord may, but shall not be required to, make repairs,
alterations and additions in or to the Premises and redecorate the same to the
extent Landlord deems necessary or desirable, and Tenant shall, upon demand, pay
the cost thereof, together with Landlord's expenses of reletting, including,
without limitation, any broker's commission incurred by Landlord. Landlord and
Tenant agree that nevertheless Landlord shall at most be required to use only
the same efforts Landlord then uses to lease premises in the Building generally
and that in any case that Landlord shall not be required to give any preference
or priority to the showing or leasing of the Premises over any other space that
Landlord may be leasing or have available and may place a suitable prospective
tenant in any such other space regardless of when such other space becomes
available. Landlord shall not be required to observe any instruction given by
Tenant about any reletting or accept any tenant offered by Tenant unless such
offered tenant has a credit-worthiness acceptable to Landlord and leases the
entire Premises upon terms and conditions including a rate of rent (after giving
effect to all expenditures by Landlord for tenant improvements, broker's
commissions and other leasing costs) all no less favorable to Landlord than as
called for in this Lease, nor shall Landlord be required to make or permit any
assignment or sublease for more than the current term or which Landlord would
not be required to permit under the provisions of Article 9.

          18.1.4.3 Until such time as Landlord shall elect to terminate the
Lease and shall thereupon be entitled to recover the amounts specified in such
case in Section 18.1.3, Tenant shall pay to Landlord upon demand the full amount
of all rent, including any amounts treated as additional rent under this Lease
and other sums reserved in this Lease for the remaining Term, together with the
costs of repairs, alterations, additions, redecorating and Landlord's expenses
of reletting and the collection of the rent accruing therefrom (including
attorney's fees and broker's commissions), as the same shall then be due or
become due from time to time, less only such consideration as Landlord may have
received from any reletting of the Premises; and Tenant agrees that Landlord may
file suits from time to time to recover any sums falling due under this Article
18 as they become due. Any proceeds of reletting by Landlord in excess of the
amount then owed by Tenant to Landlord from time to time shall be credited
against Tenant's future obligations under this Lease but shall not otherwise be
refunded to Tenant or inure to Tenant's benefit.

     18.2 Landlord may, at Landlord's option, enter into and upon the Premises
if Landlord determines in its sole discretion that Tenant is not acting within a
commercially reasonable time to maintain, repair or replace anything for which
Tenant is responsible under this Lease and correct the same, without being
deemed in any manner guilty of trespass, eviction or forcible entry and detainer
and without incurring any liability for any damage or interruption of Tenant's
business resulting therefrom. If Tenant shall have vacated the Premises.
Landlord may at Landlord's option re-enter the Premises at any time during the
last six months of the then current Term of this Lease and make any and all such
changes, alterations, revisions, additions and tenant and other improvements in
or about the Premises as Landlord shall elect, all without any abatement of any
of the rent otherwise to be paid by Tenant under this Lease.

     18.3 If, on account of any breach or default by Tenant in Tenant's
obligations under the terms and conditions of this Lease, it shall become
necessary or appropriate for Landlord to employ or consult with an attorney
concerning or to enforce or defend any of Landlord's rights or remedies arising
under this Lease, Tenant agrees to pay all Landlord's attorney's

<PAGE>

fees so incurred.

     18.4 Pursuit of any of the foregoing remedies shall not preclude pursuit of
any of the other remedies provided in this Lease or any other remedies provided
by Law (all such remedies being cumulative), nor shall pursuit of any remedy
provided in this Lease constitute a forfeiture or waiver of any rent due to
Landlord under this Lease or of any damages accruing to Landlord by reason of
the violation of any of the terms, provisions and covenants contained in this
Lease.

     18.5 No act or thing done by Landlord or its agents during the Term shall
be deemed a termination of this Lease or an acceptance of the surrender of the
Premises, and no agreement to terminate this Lease or accept a surrender of said
Premises shall be valid, unless in writing signed by Landlord. No waiver by
Landlord of any violation or breach of any of the terms, provisions and
covenants contained in this Lease shall be deemed or construed to constitute a
waiver of any other violation or breach of any of the terms, provisions and
covenants contained in this Lease. Landlord's acceptance of the payment of
rental or other payments after the occurrence of an Event of Default shall not
be construed as a waiver of such Default, unless Landlord so notifies Tenant in
writing. Forbearance by Landlord in enforcing one or more of the remedies
provided in this Lease upon an Event of Default shall not be deemed or construed
to constitute a waiver of such Default or of Landlord's right to enforce any
such remedies with respect to such Default or any subsequent Default.

     18.7 Any and all property which may be removed from the Premises by
Landlord pursuant to the authority of this Lease or of law, to which Tenant is
or may be entitled. may be handled, removed and/or stored, as the case may be,
by or at the direction of Landlord but at the risk, cost and expense of Tenant,
and Landlord shall in no event be responsible for the value, preservation or
safekeeping thereof. Tenant shall pay to Landlord, upon demand, any and all
expenses incurred in such removal and all storage charges against such property
so long as the same shall be in Landlord's possession or under Landlord's
control. Any such property of Tenant not retaken by Tenant from storage within
thirty (30) days after removal from the Premises shall, at Landlord's option, be
deemed conveyed by Tenant to Landlord under this Lease as by a bill of sale
without further payment or credit by Landlord to Tenant.

19. TENANT'S BANKRUPTCY OR INSOLVENCY.

     19.1 If at any time and for so long as Tenant shall be subjected to the
provisions of the United States Bankruptcy Code or other law of the United
States or any state thereof for the protection of debtors as in effect at such
time (each a "Debtor's Law"):

          19.1.1 Tenant, Tenant as debtor-in-possession, and any trustee or
receiver of Tenant's assets (each a "Tenant's Representative") shall have no
greater right to assume or assign this Lease or any interest in this Lease, or
to sublease any of the Premises than accorded to Tenant in Article 9, except to
the extent Landlord shall be required to permit such assumption, assignment or
sublease by the provisions of such Debtor's Law. Without limitation of the
generality of the foregoing, any right of any Tenant's Representative to assume
or assign this Lease or to sublease any of the Premises shall be subject to the
conditions that:

               19.1.1.1 Such Debtor's Law shall provide to Tenant's 
Representative aright of assumption of this Lease which Tenant's Representative
shall have timely exercised and Tenant's Representative shall have fully cured
any default of Tenant under this Lease.

<PAGE>

               19.1.1.2 Tenant's Representative or the proposed assignee, as
the case shall be, shall have deposited with Landlord as security for the timely
payment of rent an amount equal to the larger of: (a) three months' Rent and
other monetary charges accruing under this Lease; and (b) any sum specified in
Article 5; and shall have provided Landlord with adequate other assurance of the
future performance of the obligations of the Tenant under this Lease. Without
limitation, such assurances shall include, at least, in the case of assumption
of this Lease, demonstration to the satisfaction of the Landlord that Tenant's
Representative has and will continue to have sufficient unencumbered assets
after the payment of all secured obligations and administrative expenses to
assure Landlord that Tenant's Representative will have sufficient funds to
fulfill the obligations of Tenant under this Lease; and, in the case of
assignment, submission of current financial statements of the proposed assignee,
audited by an independent certified public accountant reasonably acceptable to
Landlord and showing a net worth and working capital in amounts determined by
Landlord to be sufficient to assure the future performance by such assignee of
all of the Tenant's obligations under this Lease.

               19.1.1.3 The assumption or any contemplated assignment of this
Lease or subleasing any part of the Premises, as shall be the case, will not
breach any provision in any other lease, mortgage, financing agreement or other
agreement by which Landlord is bound.

               19.1.1.4 Landlord shall have. or would have had absent the
Debtor's Law, no right under Article 9 to refuse consent to the proposed
assignment or sublease by reason of the identity or nature of the proposed
assignee or Sublessee or the proposed use of the Premises concerned.

20. QUIET ENJOYMENT.

Landlord represents and warrants that it has full right and authority to enter
into this Lease and that Tenant, while paying the rental and performing its
other covenants and agreements contained in this Lease, shall peaceably and
quietly have, hold and enjoy the Premises for the Term without hindrance or
molestation from Landlord subject to the terms and provisions of this Lease.
Landlord shall not be liable for any interference or disturbance by other
tenants or third persons, nor shall Tenant be released from any of the
obligations of this Lease because of such interference or disturbance.

21. DAMAGE BY FIRE, ETC.

     21.1 Landlord shall maintain all insurance policies deemed by Landlord to
be reasonably necessary or desirable and relating in any manner to the
protection, preservation or operation of the Premises, including by not limited
to, standard fire and extended coverage insurance covering the Premises in an
amount not less than ninety percent (90%) of the replacement cost thereof
insuring against the perils of fire and lightning and including extended
coverage or, at Landlord's option, all risk coverage and, if Landlord so elects,
earthquake, flood and wind coverages and Tenant shall pay, as additional rent,
the cost of such policies upon demand by Landlord. Such insurance shall be for
the sole benefit of Landlord and under its sole control. Tenant shall not take
out separate insurance concurrent in form or contributing in the event of loss
with that required to be maintained by Landlord hereunder unless Landlord is
included as a loss payee thereon. Tenant shall immediately notify Landlord
whenever any such separate insurance is taken out and shall promptly deliver to
Landlord the policy or policies of such insurance.

     21.2 In the event the Premises or the Building are damaged by fire or other
cause and in Landlord's reasonable estimation such damage can be materially
restored within one hundred eighty (180) days, Landlord shall forthwith repair
the same and this Lease shall remain in full force and effect, except that
Tenant shall be entitled to a proportionate abatement in rent from the date of
such damage. Such abatement of rent shall be made pro rata in accordance with
the extent to which the damage and the making of such repairs shall interfere
with the use and occupancy by Tenant of the Premises from time to time. Within
thirty (30) days from the date of such damage, Landlord shall notify Tenant, in
writing, of Landlord's reasonable estimation of the length of time within which
material restoration can be made, and Landlord's determination shall be binding
on Tenant. For purposes of this Lease, the Building or Premises shall be deemed
materially restored if they are in such condition as would not prevent or
materially interfere with Tenant's use of the Premises for the purpose for which
it was being used immediately before such damage.

     21.3 If such repairs cannot, in Landlord's reasonable estimation, be made
within one hundred eighty (180) days, Landlord and Tenant shall each have the
option of giving the other at any time within forty-five (45) days after such
damage, notice terminating this Lease as of the


<PAGE>

date of such damage. In the event of the giving of such notice, this Lease shall
expire and all interest of the Tenant in the Premises shall terminate as of the
date of such damage at if such date had been originally fixed in this Lease for
the expiration of the Term. In the event that neither Landlord nor Tenant
exercises its option to terminate this Lease, then Landlord shall repair or
restore such damage, this Lease continuing in full force and effect, and the
rent hereunder shall be proportionately abated as provided in Section 21.2.

     21.4 Landlord shall not be required to repair or replace any damage or loss
by or from fire or other cause to any panelings, decorations, partitions,
additions, railings, ceilings, floor coverings, office fixtures or any other
property or improvements installed on the Premises or belonging to Tenant. Any
insurance which may be carried by Landlord or Tenant against loss or damage to
the Building or Premises shall be for the sole benefit of the party carrying
such insurance and under its sole control.

     21.5 In the event that Landlord should fail to complete such repairs and
material restoration within forty-five (45) days after the date estimated by
Landlord therefor as extended by this Section 21.5, Tenant may at its option and
as its sole remedy terminate this Lease by delivering written notice to
Landlord, within fifteen (15) days after the expiration of said period of time,
whereupon the Lease shall end on the date of such notice or such later date
fixed in such notice as if the date of such notice was the date originally fixed
in this Lease for the expiration of the Term; provided, however, that if
construction is delayed because of changes, deletions or additions in
construction requested by Tenant, strike, lockouts, casualties, Acts of God,
war, material or labor shortages, government regulation or control or other
causes beyond the reasonable control of Landlord, the period for restoration,
repair or rebuilding shall be extended for the amount or time Landlord is so
delayed.

     21.6 Notwithstanding anything to the contrary contained in this Article:
(a) Landlord shall not have any obligation whatsoever to repair, reconstruct, or
restore the Premises when the damages resulting from any casualty covered by the
provisions of this Article 21 occur during the last twelve (12) months of the
Term or any extension thereof, but if Landlord determines not to repair such
damages Landlord shall notify Tenant within 30 days after the casualty and if
such damages shall render any material portion of the Premises untenantable as
determined by Tenant acting reasonably Tenant shall have the right to terminate
this Lease by notice to Landlord within fifteen (15) days after receipt of
Landlord's notice; and (b) in the event the holder of any indebtedness secured
by a mortgage or deed of trust covering the Premises or Building requires that
any insurance proceeds be applied to such indebtedness, then Landlord shall have
the right to terminate this Lease by delivering written notice of termination to
Tenant within fifteen (15) days after such requirement is made by any such
holder, whereupon this Lease shall end on the date of such damage as if the
date of such damage were the date originally fixed in this Lease for the
expiration of the Term.

     21.7 In the event of any damage or destruction to the Building or Premises
by any peril covered by the provisions of this Article 21, it shall be Tenant's
responsibility to properly secure the Premises and upon notice from Landlord to
remove forthwith, at its sole cost and expense, such portion of all of the
property belonging to Tenant or its licensees from such portion or all of the
Building or Premises as Landlord shall reasonably request.

22. EMINENT DOMAIN.

If all or any substantial part of the Premises shall be taken or appropriated by
any public or quasi-public authority under the power of eminent domain, or
conveyance in lieu of such appropriation, either party to this Lease shall have
the right, at its option, of giving the other, at any time within thirty (30)
days after such taking, notice terminating this Lease, except that Tenant may
only terminate this Lease by reason of taking or appropriation, if such taking
or appropriation shall be so substantial as to materially interfere with
Tenant's use and occupancy of the Premises. If neither party to this Lease shall
so elect to terminate this Lease, the rental thereafter to be paid shall be
adjusted on a fair and equitable basis under the circumstances. In addition to
the rights of Landlord above, if any substantial part of the Building shall be
taken or appropriated by any public or quasi-public authority under the power of
eminent domain or conveyance in lieu thereof, and regardless of whether the
Premises or any part thereof are so taken or appropriated, Landlord shall have
the right, at its sole option, to terminate this Lease. Landlord shall be
entitled to any and all income, rent, award, or any interest whatsoever in or
upon any such sum, which may be paid or made in connection with any such public
or quasi-public use or purpose, and Tenant hereby assigns to Landlord any
interest it may have in or claim to all or any part of such sums, other than any
separate award which may be made with respect to Tenant's trade fixtures and
moving expenses; Tenant shall make no claim for the value of any unexpired Term.

23. SALE BY LANDLORD.

In event of a sale or conveyance by Landlord of the Building, the same shall
operate to release Landlord from any future liability upon any of the covenants
or conditions, expressed or implied, contained in this Lease in favor of Tenant,
and in such event Tenant agrees to look


<PAGE>

solely to the responsibility of the successor in interest of Landlord in and to
this Lease. Except as set forth in this Article 23, this Lease shall not be
affected by any such sale and Tenant agrees to attorn to the purchaser or
assignee. If any security has been given by Tenant to secure the faithful
performance of any of the covenants of this Lease, Landlord may transfer or
deliver said security, as such, to Landlord's successor in interest and
thereupon Landlord shall be discharged from any further liability with regard to
said security.

24. ESTOPPEL CERTIFICATES.

Within ten (10) days following any written request which Landlord may make from
time to time, Tenant shall execute and deliver to Landlord or mortgagee or
prospective mortgagee a sworn statement certifying: (a) the date of commencement
of this Lease; (b) the fact that this Lease is unmodified and in full force and
effect (or, if there have been modifications to this Lease, that this lease is
in full force and effect, as modified, and stating the date and nature of such
modifications); (c) the date to which the rent and other sums payable under this
Lease have been paid; (d) the fact that there are no current material defaults
under this Lease by either Landlord or Tenant except as specified in Tenant's
statement; and (e) such other matters as may be requested by Landlord. Landlord
and Tenant intend that any statement delivered pursuant to this Article 24 may
be relied upon by any mortgagee, beneficiary or purchaser and Tenant shall be
liable for all loss, cost or expense resulting from the failure of any sale or
funding of any loan caused by any material misstatement contained in such
estoppel certificate. Tenant irrevocably agrees that if Tenant fails to execute
and deliver such certificate within such ten (10) day period Landlord or
Landlord's beneficiary or agent may execute and deliver such certificate on
Tenant's behalf, and that such certificate shall be fully binding on Tenant.

25. SURRENDER OF PREMISES.

     25.1 Tenant shall, at least thirty (30) days before the last day of the
Term, arrange to meet Landlord for a joint inspection of the Premises. In the
event of Tenant's failure to arrange such joint inspection to be held prior to
vacating the Premises, Landlord's inspection at or after Tenant's vacating the
Premises shall be conclusively deemed correct for purposes of determining
Tenant's responsibility for repairs and restoration.

     25.2 At the end of the Term or any renewal of the Term or other sooner
termination of this Lease, Tenant will peaceably deliver up to Landlord
possession of the Premises, together with all improvements or additions upon or
belonging to the same, by whomsoever made, in the same conditions received or
first installed, broom clean and free of all debris, expecting only ordinary
wear and tear and damage by fire or other casualty. Tenant may, and at
Landlord's request shall, at Tenant's sole cost, remove upon termination of this
Lease, any and all furniture, furnishings, movable partitions of less than full
height from floor to ceiling, trade fixtures and other property installed by
Tenant, title to which shall not be in or pass automatically to Landlord upon
such termination, repairing all damage caused by such removal. Property not so
removed shall, unless requested to be removed, be deemed abandoned by the Tenant
and title to the same shall thereupon pass to Landlord under this Lease as by a
bill of sale. All other alterations, additions and improvements in, on or to the
Premises shall be dealt with and disposed of as provided in Article 6.

     25.3 All obligations of Tenant under this Lease not fully performed as of
the expiration or earlier termination of the Term shall survive the expiration
or earlier termination of the Term. In the event that Tenant's failure to
perform prevents Landlord from releasing the Premises, Tenant shall continue to
pay rent pursuant to the provisions of Article 14 until such performance is
complete. Upon the expiration or earlier termination of the Term, Tenant shall
pay to Landlord the amount, as estimated by Landlord, necessary to repair and
restore the Premises as provided in this Lease and/or to discharge Tenant's
obligation for unpaid amounts due or to become due to Landlord. All such amounts
shall be used and held by Landlord for payment of such obligations of Tenant,
with Tenant being liable for any additional costs upon demand by Landlord, or
with any excess to be returned to Tenant after all such obligations have been
determined and satisfied. Any otherwise unused Security Deposit shall be
credited against the amount payable by Tenant under this Lease.

26. NOTICES.

Any notice or document required or permitted to be delivered under this Lease
shall be addressed to the intended recipient, shall be transmitted personally.
by fully prepaid registered or certified United States Mail return receipt
requested, or by reputable independent contract delivery service furnishing a
written record of attempted or actual delivery, and shall be deemed to be
delivered when tendered for delivery to the addressee at its address set forth
on the Reference Page, or at such other address as it has then last

27.  TAXES PAYABLE BY TENANT.

In addition to rent and other charges to be paid by Tenant under this Lease,
Tenant shall reimburse to Landlord, upon demand, any and all taxes payable by
Landlord (other than net income taxes) whether or not now customary or within
the contemplation of the parties to this Lease: (a) upon, allocable to. or
measured by or on the gross or net rent payable under this Lease, including
without limitation any gross income tax or excise tax levied by the State, any
political subdivision thereof, or the Federal Government with respect to the
receipt of such rent; (b) upon or with respect to the possession, leasing,
operation, management, maintenance, alteration, repair, use or occupancy of the
Premises or any portion thereof, including any sales, use or service tax imposed
as a result thereof; (c) upon or measured by the Tenant's gross receipts or
payroll or the value of Tenant's equipment, furniture, fixtures and other
personal property of Tenant or leasehold improvements, alterations or additions
located in the Premises; or (d) upon this transaction or any document to which
Tenant is a party creating or transferring any interest of Tenant in this Lease
or the Premises. In addition to the foregoing, Tenant agrees to pay, before
delinquency, any and all taxes levied or assessed against Tenant and which
become payable during the term hereof upon Tenant's equipment, furniture,
fixtures and other personal property of Tenant located in the Premises.

28. DEFINED TERMS AND HEADINGS.

                      375 Oser Avenue, Hauppauge, New York

Addenda to Provisions of the Printed Lease:

     Section 1.2. Landlord shall indemnify and hold Tenant harmless from and
against any and all costs of any required or necessary investigation, repair,
cleanup or detoxification and the preparation of any closure or other required
plans in connection therewith, whether voluntary or compelled by governmental
authority, all to the extent resulting from or necessitated by any environmental
conditions in place prior to the Commencement Date. However, in any action to
enforce such indemnity, Tenant will have the burden of proof to show that such
conditions pro-existed the Commencement Date.

     Section 5. (a) The amount of the Security Deposit specified on the
Reference Page equals four (4) months' rent at the rate of the Monthly
Installment of Rent first payable hereunder. Upon written demand by Landlord,
Tenant shall deposit with Landlord such additional amount as shall be required
by Landlord to maintain the Security Deposit at an amount equal to four times
the sum of then-current Monthly Installment of Rent. However, effective as of
the third (3rd) anniversary of the Commencement Date, if Tenant is not then in
default, the Security Deposit will be reduced to two (2) times the Monthly
Installment of Rent, as increased from time to time.

          (b) Except to the extent Landlord is entitled to retain all or a
portion of the Security Deposit pursuant to this Lease, Landlord shall return
the Security Deposit to Tenant within thirty (30) days after the expiration of
the Term.

     Section 6.1. (a) Landlord's consent is not required for any interior
alterations which (i) are not structural; (ii) do not affect the Building's
HVAC, electrical, plumbing, mechanical or other systems; and (iii) do not cost
in excess of $10,000. However, Tenant shall notify Landlord of any such
alterations at least twenty (20) days before effecting the same.

          (b) Landlord may condition its approval of any proposed alterations,
additions or improvements upon Tenant's agreement to remove the same at the end
of the Term and restore the Premises to their prior condition, reasonable wear
and tear excepted. At the time Tenant seeks Landlord's approval of any proposed
alterations, additions or improvements, Landlord, at Tenant's request, shall
advise Tenant if Landlord will require such removal and restoration. Landlord
may require, pursuant to Section 6.4, the removal at the end of the Term of any
alterations, additions or improvements installed by Tenant without Landlord's
approval, as permitted under the preceding subparagraph (a).

     Section 7.1 (a) Landlord represents that the HVAC systems serving the
Premises will be in good working condition as of the Commencement Date; however,
the inaccuracy of this representation would not give rise to any right of
termination.


                                      R-1

<PAGE>

          (b) Except as to repairs necessitated by the negligence or breach of
Lease by Tenant, Landlord shall repair and maintain the structural portions of
the roof, walls and foundation of the Building.

     Section 11.2. If the proceeds of any Tenant insurance policies are paid by
the insurer to Landlord, and if Landlord has no rightful interest in such
proceeds, Landlord shall immediately endorse or pay such proceeds over to
Tenant.

     Section 17.1.4. If an involuntary bankruptcy petition is filed against
Tenant, the same shall not constitute an Event of Default so long as Tenant is
diligently contesting the petition and the petition is dismissed not later than
sixty (60) days after filing.

     5ection 26. Landlord shall endeavor to deliver a concurrent copy of any
notice to Tenant to Ronald G. Goldman, Horowitz & Goldman, 595 Stewart Avenue,
Suite 710, Garden City, New York 11530; but failure to deliver such copy shall
not render defective any notice which is otherwise proper.

                                                                   Exhibit 10.12

STANDARD COMMERCIAL LEASE                                                  1/91 

                                LEASE AGREEMENT

            THIS LEASE made and entered into between RREEF USA FUND I, a
California Group Trust ("Landlord") and NETSAT EXPRESS, INC., a division of
Worldcomm Systems Inc. ("Tenant").

                              1. Premises and Term

            In consideration of the obligation of Tenant to pay rent and of the
other terms, provisions and covenants hereof, Landlord leases to Tenant, and
Tenant leases from Landlord, that portion as outlned on the site plan attached
as Exhibit B, including any parking areas and truck loading areas specifically
marked on Exhibit B for the exclusive use of Tenant (the "Premises") of certain
real property legally described in Exhibit A and the buildings and improvements
thereon (the "Building"). KNOWN AS 400 OSER AVENUE CONSISTING OF APPROXIMATELY
3,000SF - SUITE 300.

            Taking of possession by Tenant shall be deemed to establish
conclusively that the Premises have been so completed and that the Premises are
in good and satisfactory condition, as of when possession was so taken (except
for such items Landlord is permitted to complete at a later date because of
weather conditions or other causes beyond Landlord's reasonable control, which
items shall be specified by Landlord to Tenant in writing). Tenant acknowledges
that no representations as to the repair of the Premises have been made by
Landlord, unless expressly set forth in this Lease.

                         2. Base Rent; Security Deposit

            Tenant agrees to pay to Landlord base rent for the entire Term as
the rate shown on Exhibit B one such monthly installment shall be due and
payable without demand on or before the first day of each calendar month during
the Term, provided, that the rental payment for any fractional calendar month
shall be prorated. In addition, Tenant agrees to deposit with Landlord on the
date hereof the sum shown on Exhibit B as the security deposit, which sum shall
be held by Landlord, without obligation for interest, as security for the full,
timely and faithful performance of Tenant's obligations under this Lease, it
being agreed that such deposit is not an advance rental deposit or a measure of
Landlord's damages. Upon the occurrence of any event of default by Tenant,
Landlord may, from time to time, without prejudice to any other remedy, use such
fund to make good any arrears of rent or other payments due Landlord hereunder,
and any other damage, injury, expense or liability caused by Tenant's default;
and Tenant shall pay to Landlord on demand the amount so applied in order to
restore the security deposit to its orginal amount. Any remaining balance shall
be returned at such time after termination of this Lease when Landlord shall
have determined that all Tenant's obligations under this Lease have been
fulfilled.

                                     3. Use

            A. The Premises shall be continuously used by Tenant, but only for
the purpose of receiving, storing, shipping and selling (other than at retail)
products, materials and merchandise made and/or distributed by Tenant and for no
other use or purpose. Tenant shall at its own cost and expense obtain any and
all licenses and permits necessary for any such use. The outside storage of any
property (including, without limitation, overnight parking of trucks and other
vehicles) is prohibited. Tenant shall comply with all governmental laws,
ordinances and regulations ("Laws") applicable to its use and occupancy of the
Premises and shall promptly comply with all governmental orders and directives
for the correction, prevention and abatement of any violations or nuisances in
or upon, or connected with the Premises, all at Tenant's sole expense. If as a
result of any change in Laws, the Premises must be altered to lawfully
accommodate the use and occupancy thereof, such alterations shall be made only
with the consent of Landlord, but the entire cost thereof shall be borne by
Tenant; provided, that, the necessity of Landlord's consent shall in no way
create any liability against Landlord for the failure of the Tenant to comply
with such Laws. Tenant and its employees, customers and licensees shall have the
nonexclusive right to use in common with the other parties occupying the
Building, common parking areas, if any, (exclusive of any parking or work load
areas designated or to be designated by Landlord for the exclusive use of Tenant
or other tenants occupying or to be occupying other portions of the Building),
driveways and alleys adjacent to the Building. Landlord shall at all times have
the right to promulgage such reasonable rules and regulations as it deems
advisable for the safety, care and cleanliness of the Premises and for the
preservation of good order therein. Copies of all rules and regulations,
changes, and amendments will be forwarded to Tenant. Tenant shall be responsible
for the compliance with such rules and regulations by Tenant's agents,
employees, and invitees.

            B. Tenant agrees that Tenant, its agents and contractors, licensees,
or invitees shall not handle, use, manufacture, store or dispose of any
flammables, explosives, radioactive materials, hazardous wastes or materials,
toxic wastes or materials, petroleum products or derivatives or other similar
substances (collectively "Hazardous Materials") on, under, or about the
Premises, without Landlord's prior written consent in Landlord's sole
discretion. Tenant may handle, store, use or dispose of products containing
small quantities of Hazardous Materials, which products are of a type
customarily found in offices and households (such as aerosol cans containing
insecticides, toner for copies, and the like);provided that Tenant shall handle,
store, use and dispose of any such Hazardous Materials in a safe and lawful
manner and shall not allow such Hazardous Materials to contaminate the Premises
or the environment. Tenant further agrees that Tenant will not permit any
substance to come into contact with groundwater under the Premises. Any such
substance coming into contact with groundwater shall, regardless of its inherent
hazardous characteristics, be considered a Hazardous Material for purposes of
this Lease.

            C. If Landlord, in its sole discretion, believes that the Premises
or the environment have become contaminated with Hazardous Materials, Landlord,
in addition to its other rights under this Lease, may enter upon the Premises
and obtain samples from the Premises, including without limitation the soil and
groundwater under the Premises, for the purposes of analyzing the same to
determine whether and to what extent the Premises or the environment have become
so contaminated. Tenant shall reimburse Landlord for the costs of any
inspection, sampling and analysis that discloses contamination for which Tenant
is liable. Tenant may not perform any sampling, testing, or drilling to locate
any Hazardous Materials on the Premises without Landlord's to locate any
Hazardous Materials on the Premises without Landlord's prior written consent.
Any of Tenant's insurance insuring against claims of the type dealt with in this
Paragraph shall be considered primary coverage for claims against the Premises
arising out of or under this Paragraph. In the event of any transfer of Tenant's
interest under this Lease or the termination of this Lease, by lapse of time or
otherwise, Tenant shall be solely responsible for compliance with any and all
then effective Laws concerning (i) the physical condition of the Premises; or
(ii) the presence of Hazardous Materials in or on the Premises (such as the
Illinois Responsible Property Transfer Act), including but not limited to any
reporting or filing requirements imposed by such laws. Tenant's duty to pay rent
shall continue until the obligations imposed by such laws are satisfied in full
and any certificate of clearance or similar document has been delivered to
Landlord.

            D. Without limiting the above, Tenant shall reimburse, defend,
indemnify and hold Landlord harmless from and against any and all claims,
losses, liabilities, damages, costs and expenses, including without limitation,
loss of rental income, loss due to business interruption, and attorneys fees and
costs, arising out of or in any way connected with the use, manufacture,
storage, or disposal of Hazardous Materials by Tenant, its agents or contractors
on, under or about the Premises including, without limitation, the costs of any
required or necessary investigation, repair, cleanup or detoxification and the
preparation of any closure or other required plans in connection herewith,
whether voluntary or compelled by governmental authority. The indemnity
obligations of Tenant under this clause shall survive any termination of the
Lease, Tenant shall provide Landlord on a timely basis with (i) copies of all
documents, reports, and *for two (2) months , commencing July 15, 1996, and then
on a month to month term commencing September 16, 1996 and cancellable by either
party upon 30 days prior written notice which notice must be given no later than
the last day of the month preceeding the date of termination.

<PAGE>

communications with governmental authorities; and (ii) notice and an opportunity
to attend all meetings with regulatory authorities. Tenant shall comply with all
notice requirements and Landlord and Tenant agree to cooperate with governmental
authorities seeking access to the Premises for purposes of sampling or
inspection. No disturbance of Tenant's use of the Premises resulting from
activities conducted pursuant to this Paragraph shall constitute and actual or
constructive eviction of Tenant from the Premises. In the event that such
cleanup extends beyond the termination of the Lease, Tenant's obligation to pay
rent shall continue until such cleanup is completed and any certificate of
clearance or similar document has been delivered to Landlord. Rent during such
holdover period shall be at market rent; if the parties are unable to agree upon
the amount of such market rent, then the Landlord shall have the option of (a)
increasing the rent for the period of such holdover based upon the increase in
the Consumer Price Index for the third month preceding the Commencement Date to
the third month preceding the start of the holdover period; or (b) having
Landlord and Tenant each appoint a qualified MAI appraiser doing business in the
area; in turn, these two independent MAI appraisers shall appoint a third MAI
appraiser and the majority shall decide upon the fair market rental for Premises
as of the expiration of the then current term. Landlord and Tenant shall equally
share in the expense of this appraisal except that in the event the rent is
found to be within fifteen percent (15%) of the original rate quoted by
Landlord, then Tenant shall bear the full cost of all the appraisal process. In
no event shall the rent be subject to determination or modification by any
person, entity, court, or authority other than as set forth expressly herein,
and in no event shall the rent for any holdover period be less that the rent due
in the preceding period.

                                   5. Repairs

            A. Tenant shall at its own cost and expense keep and maintain all
parts of the Premises and such portion of the Building and improvements within
the exclusive control of Tenant in good condition, promptly making all necessary
repairs and replacements, whether ordinary or extraordinary, with materials and
workmanship of the same character, kind and quality as the original. Tenant as
part of its obligations hereunder shall keep the Premises in a clean and
sanitary condition. Tenant will, as far as possible keep all such parts of the
Premises from deterioration due to ordinary wear and from falling temporarily
out of repair, and upon termination of this Lease in any way Tenant will yield
up the Premises to Landlord in good condition and repair, loss by fire or other
casualty covered by insurance to be maintained by Landlord pursuant to
subparagraph 10A hereof excepted (but not excepting any damage to glass). Tenant
shall, at its own cost and expense, enter into a regularly scheduled preventive
maintenance/service contract with a maintenance contractor approved by Landlord
for servicing all heating and air conditioning systems and equipment serving the
Premises (and a copy thereof shall be furnished to Landlord). Tenant shall, at
its own cost and expense, repair any damage to the Premises resulting from
and/or caused in whole or in part by the negligence or misconduct of Tenant, its
agents, employees, invitees, or any other person entering upon the Premises as a
result of Tenant's business activities or caused by Tenant's default hereunder.

            B. Landlord shall at its expense maintain in good repair, reasonable
wear and tear and any casualty covered by insurance to be maintained by Landlord
pursuant to subparagraph 10A excepted, the foundation, roof and walls of the
Building. Tenant shall immediately give Landlord written notice of any defect or
need for repairs, after which Landlord shall have reasonable opportunity to
repair same or cure such defect. Landlord's liability with respect to any
defects, repairs or maintenance for which Landlord is responsible under any of
the provisions of this Lease shall be limited to the cost of such repairs or
maintenance or the curing of such defect. The term "walls" as used herein shall
not include windows, glass or plate glass, doors, special store fronts or office
entries.

                                  6. Alterations

            Tenants shall not make any alterations, additions or improvements
("Alterations") to the Premises without the prior written consent of Landlord,
which consent may in Landlord's sole discretion be withheld. Each request shall
be accompanied by plans detailing the proposed Alteration. In connection with
any request, Landlord may retain the services of an architect and/or engineer
and Tenant shall reimburse Landlord for the reasonable fees of such architect
and/or engineer. If Landlord shall consent to any Alterations, Tenant shall
construct the same in accordance with all Laws and shall, prior to construction,
provide such assurances to Landlord, (including but not limited to, waivers of
lien, surety company performance bonds and personal guarantees of individuals of
substance) as Landlord shall require to protect Landlord against any loss from
any mechanics', materialmen's or other liens. At the time of completion of each
Alteration, Tenant shall deliver to Landlord a set of final "as-built" plans.
All Alterations and partitions erected by Tenant shall be and remain the
property of Tenant during the Term and Tenant shall, unless Landlord otherwise
elects at the time of termination, remove all Alterations and partitions erected
by Tenant ( but not any improvements erected for Tenant by Landlord at the
commencement of the Term) and restore the Premises to their original condition
by the date of termination of this Lease or upon earlier vacating of the
Premises. All shelves, bins, machinery and trade fixtures installed by Tenant
shall be removed by the date of termination of this Lease or upon earlier
vacating of the Premises; upon any such removal Tenant shall restore the
Premises to their original condition (including the removal of all fastening
bolts and the patching of the walls and floors where necessary). All such
removals and restoration shall be accomplished in a good workmanlike manner so
as not to damage the primary structure or structural qualities of the Building.
Tenant shall not install any signs upon the Building.

                                 7. Inspections

            Landlord and Landlord's agents and representatives shall have the
right to enter and inspect the Premises at any reasonable time;(i) to ascertain
the condition of the Premises; (ii) to determine whether Tenant is diligently
fulfilling Tenant's responsibilities under the lease; (iii) to supply any
service to be provided by Landlord to Tenant hereunder;(iv) to make such repairs
as may be required or permitted to be made by Landlord under the terms of this
Lease (and may for that purpose, without abatement of rent, erect, use and
maintain scaffolding, pipes conduits, and other necessary structures in, through
or on the Premises where reasonably required by the character of the work to be
performed, provided entrance to the Premises shall not be blocked thereby, and
further provided that the business of Tenant shall not be interfered with
unreasonably); (v) to show the Premises to prospective tenants, purchasers
mortgagees; and (vi) to do any other act or thing which Landlord deems
reasonable to preserve the Premises.

                                   8. Utilities

            Tenant shall pay for all water, gas, heat, light, power, telephone,
sewer, sprinkler systems charges and other utilities and services used on or
from the Premises, including without limitation, Tenant's proportionate share as
determined by Landlord of the cost of any central station signaling system
installed in the Premises of the Building together with any taxes, penalties,
and surcharges or the like pertaining thereto and any maintenance charges for
utilities. Tenant shall furnish all electric light bulbs, tubes and ballasts,
battery packs for emergency lighting and fire extinguishers. If any such
services are not separately metered to Tenant, Tenant shall pay such proportion
of all charges jointly metered with other premises as determined by Landlord, in
its sole discretion, to be reasonable. Any such charges paid by Landlord and
assessed against Tenant shall be immediately payable to Landlord on demand and
shall be additional rent hereunder. Landlord shall in no event be liable for any
interruption or failure of utility services on or to the Premises.

                           9. Assignment and Subletting

            A. Tenant shall not have the right to assign or pledge this Lease or
to sublet the whole or any part of the Premises, whether voluntarily or by
operation of law, or permit the use or occupancy of the Premises by anyone other
than the Tenant, without the prior written consent of Landlord, which may be
withheld in Landlord's sole discretion, and such restrictions shall be binding
upon any assignee or subtenant to which Landlord has consented. In the event
Tenant desires to sublet the Premises, or any portion thereof, or assign this
Lease, Tenant shall give written notice thereof to Landlord within a reasonable
time prior to the proposed commencement date of such subletting or assignment,
which notice shall set forth the name of the proposed subtenant or assignee the
relevant terms of any sublease and copies of financial reports and other
relevant financial information on the proposed subtenant or assignee. In no
event may Tenant sublease, nor will Landlord consent to any sublease of all or
any portion of the Premises if the rent is determined in whole or in part upon
the income or profits derived by the sublessee (other than a rent based upon a
fixed percentage or percentages of receipts or sales). Notwithstanding any
permitted assignment or subletting, Tenant shall at all times remain directly,
primarily and fully responsible and liable for the payment of the rent herein
specified and for compliance with all of its other obligations under this Lease.
Upon the occurrence of an event of default, if the Premises or any part thereof
are then assigned or sublet, Landlord, in addition to any other remedies herein
provided, or provided by law, may, at its option, collect directly from such
assignee or subtenant all rents due and becoming due to Tenant under such
assignment or sublease and apply such rent against any sums due to Landlord from
Tenant hereunder, and no such collection shall be construed to constitute a
novation or a release of Tenant from the further performance of Tenant's
obligations hereunder.

            B. In addition to, but not in limitation of, Landlord's right to
approve of any subtenant or assignee, Landlord shall have the option, in its
sole discretion, in the event of any proposed subletting or assignment, to
terminate this Lease, or in the case of a proposed subletting of less than the
entire Premises, to recapture the portion of the Premises to be sublet, as of
the date the subletting or assignment is to be effective. The option shall be
exercised, if at all, by Landlord giving Tenant written notice thereof within
sixty (60) days following Landlord's receipt of Tenant's written notice as
required above. If this Lease shall be terminated with respect to the entire
Premises pursuant to this paragraph, the Term shall end on the date stated in
the Tenant's notice as the effective date of the sublease or assignment as if
that date had been originally fixed in the Lease for the expiration of the Term.
If Landlord recaptures under this paragraph only a portion of the Premises, the
rent during the unexpired Term shall abate proportionately based on the rent per
square foot contained in this Lease. In the event that Tenant sublets, assigns
or otherwise transfers its interest in this Lease and at any time receives
periodic rent and/or other consideration which exceeds that which Tenant would
at that time be obligated to pay to Landlord, Tenant shall pay to Landlord fifty
percent (50%) of the gross increase in such rent and fifty percent (50%) of any
other consideration as received by Tenant. Tenant shall pay to Landlord, on
demand, a reasonable service charge for the processing of the application for
consent and preparation of the consent and/or the assumption documents.

            C. It shall not be unreasonable for Landlord to withhold its consent
to any proposed assignment or sublease if (i) the proposed assignee's or
sublessee's anticipated use of the Premises involves the generation, storage,
use, treatment or disposal of Hazardous Materials;(ii) the proposed assignee or
sublessee has been required by any prior landlord, lender, or governmental
authority to take remedial action in connection with Hazardous Materials
contaminating a property if the contamination resulted from such assignee's or
sublessee's actions or use of the property in question; or (iii) the proposed
assignee or sublessee is subject to an enforcement order issued by any
governmental authority in connection with the use, disposal, or storage of a
Hazardous Material.

                          10. Casualty and Condemnation

            A. Landlord shall maintain all insurance policies deemed by Landlord
to be reasonably necessary or desirable and relating in any manner to the
protection, preservation or operation of the Building, including standard fire
and extended coverage insurance covering the Building in an amount not less than
ninety percent (90%) of the replacement cost thereof or, at Landlord's option,
all risk coverage and, if Landlord so elects, earthquakes, flood and wind
coverages. Subjects to the provisions of subparagraph 10B below, such insurance
shall be for the sole benefit of Landlord and under its sole control. Tenant
shall not take out separate insurance concurrent in form or contributing in the
event of loss with that required to be maintained by the Landlord hereunder.
Tenant shall maintain insurance on all Alterations erected by or on behalf of
Tenant in, on or about the Premises (but not any improvements erected for Tenant
by Landlord at the commencement of the Term) in an amount not less than ninety
percent (90%) of the replacement cost thereof. Such insurance shall insure
against the perils and be in form, including stipulated endorsements, as
provided in subparagraph 10A. Such insurance shall be for the sole benefit of
Tenant and under its sole control provided that Tenant shall be obligated to
immediately commence the rebuilding of the improvements erected by tenant and to
apply such proceeds in payment of the cost thereof.

<PAGE>

            B. If the Building should be damaged by any peril covered by the
insurance to be provided by Landlord under subparagraph 10A, but only to such
extent that the Building can in Landlord's estimation be materially restored
within two hundred fifty (250) days after the date upon which Landlord is
notified by Tenant of such damage (except that Landlord may elect not to rebuild
if such damage occurs during the last year of the Term), this Lease shall not
terminate, and Landlord shall at its sole cost and expense thereupon proceed
with reasonable diligence to rebuild and repair the Building to substantially
the condition in which they existed prior to such damage, except Landlord shall
not be required to rebuild, repair or replace any part of the partitions,
fixtures, additions and other improvements which may have been placed in, on or
about the Premises by Tenant. For purposes hereof the Building shall be deemed
"materially restored" if it is in such condition as would not prevent or
materially interfere with Tenant's use of the Premises for the purpose for which
they were then being used. If the Premises are untenantable in whole or in part
following such damage, the rent payable hereunder during the period in which the
Premises are untenantable shall be reduced to such extent as may be fair and
reasonable. In the event that Landlord should fail to complete such material
restoration within two hundred fifty (250) days after the date upon which
Landlord is notified by Tenant of such damage, Tenant may at its option
terminate this Lease within thirty (30) days thereafter by delivering written
notice of termination to Landlord as Tenant's exclusive remedy, whereupon the
Term shall end on the date of such notice as if the date of such notice were the
date originally fixed in the Lease for the expiration of the Term; provided,
however, that if construction is delayed because of changes, deletions, or
additions in construction requested by Tenant, strikes, lockouts, casualties,
acts of God, war, material or labor shortages, governmental regulation or
control or other causes beyond the reasonable control of Landlord, the period
for restoration, repair or rebuilding shall be extended for the amount of time
Landlord is so delayed. If the Building should be damaged or destroyed and
Landlord is not required to rebuild pursuant to the provisions of subparagraph
10B, this Lease shall terminate upon notice to Tenant, given within sixty (60)
days after Landlord is notified by Tenant of such damage, effective as of the
date of such damage as if the date had been originally fixed in the Lease for
the expiration of the Term.

            C. Notwithstanding anything herein to the contrary, in the event the
holder of any indebtedness secured by a mortgage or deed of trust covering the
Premises or the Building requires that the insurance proceeds be applied to such
indebtedness, then Landlord shall have the right to terminate this Lease by
delivering written notice of termination to Tenant within fifteen (15) days
after such request is made by any such holder, whereupon the Lease shall end on
the date of such damage as if the date of such damage were the date originally
fixed in the Lease for the expiration of the Term.

            D. Each of Landlord and Tenant hereby releases the other from any
and all liability or responsibility to the other or anyone claiming through or
under them by way of subrogation or otherwise for any loss or damage to property
caused by fire, extended coverage perils, vandalism or malicious mischief,
sprinkler leakage, or any other perils insured in policies of insurance covering
such property, even if such loss or damage shall have been caused by the fault
or negligence of the other party, or anyone for whom such party may be
responsible, including any other tenants or occupants of the remainder of the
Building; provided, however, that this release shall be applicable and in force
and effect only to the extent that such release shall be lawful at that time and
in any event only with respect to loss or damage occurring during such times as
the releasor's policies shall contain a clause or endorsement to the effect that
any such release shall not adversely affect or impair said policies or prejudice
the right of the releasor to recover thereunder and then only to the extent of
the insurance proceeds payable under such policies. Each of Landlord and Tenant
agrees that it will request its insurance carriers to include in its policies
such a clause or endorsement.

            E. If the whole or any substantial part of the Premises or Building
should be taken for any public or quasi-public use under any Law or by right of
eminent domain, or by private purchase in lieu thereof (a "Condemnation") and
the taking would prevent or materially interfere with the use of Premises or the
Building for the purpose for which they are then being used, this Lease shall
terminate effective when the physical taking shall occur as if the date of such
taking were the date originally fixed in the Lease for the expiration of the
Term. If part of the Premises shall be Condemned, and this Lease is not
terminated as provided above, this Lease shall not terminate but the rent
payable hereunder during the unexpired portion of this Lease shall be reduced to
such extent as may be fair and reasonable, Landlord shall undertake to restore
the Premises to a condition suitable for Tenant's use, as near to the condition
thereof immediately prior to such taking as is reasonably feasible. In the event
of any such Condemnation, Landlord and Tenant shall each be entitled to receive
and retain such separate awards and/or portion of lump sum awards as may be
allocated to their respective interests in any condemnation proceedings;
provided that Tenant shall not be entitled to receive any award for Tenant's
loss of its leasehold interest, the right to such award being hereby assigned by
Tenant to Landlord.

                                  11. Liability

            Landlord shall not be liable to Tenant or Tenant's employees,
agents, patrons or visitors, or to any other person whomsoever, for any injury
to persons or damage to property on or about the Premises, the Building
resulting from and/or caused in part or whole by the negligence or misconduct of
Tenant, its agents, employees, invitees or any other person entering upon the
Premises, or caused by the Building becoming out of repair, or caused by leakage
of gas, oil, water or steam or by electricity emanating from the Building, or
due to any cause whatsoever, and Tenant hereby covenants and agrees that it will
at all times indemnify and hold safe and harmless the Building and Landlord from
any loss, liability, claims, suits, costs, expenses, including attorney's fees
and damages, both real and alleged, arising out of any such damage or injury;
except injury to persons or damage to property the sole cause of which is the
negligence of Landlord or the failure of Landlord to repair any part of the
Premises which Landlord is obligated to repair and maintain hereunder within a
reasonable time after the receipt of written notice from Tenant of needed
repairs. Tenant shall procure and maintain throughout the Term a policy or
policies of insurance, in form and substance satisfactory to Landlord, at
Tenant's sole cost and expense, insuring Landlord, Landlord's mortgagee, if any,
and Tenant against all claims, demands or actions arising out or in connection
with: (i) the Premises; (ii) the condition of the Premises; (iii) Tenant's
operations in and maintenance and use of the Premises; and (iv) Tenant's
liability assumed under this Lease, the limits of such policy or policies to be
in the amount of not less than Two Million Dollars ($2,000,000) per occurrence
in respect of injury to persons (including death) and in the amount of not less
than Five Hundred Thousand Dollars ($500,000) per occurrence in respect of
property damage or destruction, including loss of use thereof.

                                12. Holding Over

            Tenant will, at the termination of this Lease by lapse of time or
otherwise, yield up immediate possession to Landlord. If Tenant retains
possession of the Premises or any part thereof after such termination, then
Landlord may, at its option, serve written notice upon Tenant that such holding
over constitutes any one of (i) renewal of this Lease for one year, and from
year to year thereafter, or (ii) creation of month to month tenancy, upon the
terms and conditions set forth in this Lease, or (iii) creation of a tenancy at
sufferance, in any case upon the terms and conditions set forth in this Lease;
provided, however, that the monthly rental (or daily rental under clause (iii))
shall, in addition to all other sums which are to be paid by Tenant hereunder,
whether or not as additional rent, be equal to double the total rental being
paid monthly to Landlord under this Lease immediately prior to such termination
(prorated in the case of clause (iii) on the basis of a 365 day year for each
day Tenant remains in possession). If no such notice is served, then a tenancy
at sufferance shall be deemed to be created at the rent in the preceeding
sentence. Tenant shall also pay to Landlord all damages sustained by Landlord
resulting from retention of possession by Tenant, including the loss of any
proposed subsequent tenant for any portion of the Premises. The provisions of
this paragraph shall not constitute a waiver by Landlord of any right of
re-entry nor shall receipt of any rent or any other act in apparent affirmance
of the tenancy operate as a waiver of the right to terminate this Lease.

                               13. Quiet Enjoyment

            Landlord covenants that it now has, or will acquire before Tenant
takes possession of the Premises, good title to the Premises. In the event this
Lease is a sublease, then Tenant agrees to take the Premises subject to the
provisions of the prior leases. Landlord represents and warrants that it has
full right and authority to enter into this Lease and that Tenant, upon paying
the rental herein set forth, and performing its other covenants and agreements
herein set forth shall peaceably and quietly have, hold and enjoy the Premises
for the Term without hindrance or molestation from Landlord, subject to the
terms and provisions of this Lease. Landlord agrees to make reasonable efforts
to protect Tenant from interference or disturbance by other tenants or third
persons; however, Landlord shall not be liable for any such interference or
disturbance, nor shall Tenant be released from any of the obligations of this
Lease because of such interference or disturbance.

                              14. Events of Default

            The following events shall be deemed to be events of default by
Tenant under this Lease:

            (a) Tenant shall fail to pay when or before due any sum of money
becoming due to be paid to Landlord hereunder, whether such sum be any
installment of the rent herein reserved, any other amount treated as additional
rent hereunder, or any other payment or reimbursement to Landlord required
herein, and such failure shall continue for a period of five (5) days from the
date such payment was due; or

            (b) Tenant shall fail to comply with any term, provision or covenant
of this Lease other than by failing to pay when or before due any sum of money
becoming due to be paid to Landlord hereunder, and shall not cure such failure
within twenty (20) days (forthwith, if the default involves a hazardous
condition) after written notice thereof to Tenant; or

            (c) Tenant shall fail to immediately vacate the Premises upon
termination of this Lease or upon termination of Tenant's right to possession
only; or

            (d) The leasehold interest of Tenant shall be levied upon under
execution or be attached by process of law or Tenant shall fail to contest
diligently the validity of any lien or claimed lien and give sufficient security
to Landlord to insure payment thereof or shall fail to satisfy any judgment
rendered thereon and have the same released, and such default shall continue for
ten (10) days after written notice thereof to Tenant.

                                  15. Remedies

            Upon the occurrence of any of such events of default described in
Paragraph 14 hereof or elsewhere in this Lease, Landlord shall have the option
to pursue any one or more of the following remedies without any notice or demand
whatsoever:

            (a) Landlord may, at its election, terminate this Lease or terminate
Tenant's right to possession only, without terminating the Lease.

            (b) Upon any such termination of this Lease, or upon any termination
of Tenant's right to possession without termination of the Lease, Tenant shall
surrender possession and vacate the Premises immediately, and deliver possession
thereof to Landlord, and Tenant hereby grants to Landlord full and free license
to enter into and upon the Premises in such event and to repossess Landlord of
the Premises as of Landlord's former estate and to expel or remove Tenant and
any others who may be occupying or within the Premises and to remove any and all
property therefrom without being deemed in any manner guilty of trespass,
eviction or forcible entry or detainer and without incurring any liability for
any damage resulting therefrom, Tenant hereby waiving any right to claim damage
for such re-entry and expulsion, and without relinquishing Landlord's right to
rent or any other right given to Landlord hereunder or by operation of law.

            (c) Upon any termination of this Lease, Landlord shall be entitled
to recover as damages, all rent, including any amounts treated as additional
rent hereunder, and other sums due and payable by Tenant on the date of
termination, plus the sum of (i) an amount equal to the then present value of
the rent, including any amounts treated as additional rent hereunder, and other
sums provided herein to be paid by Tenant for the residue of the stated Term,
less the fair rental value of the Premises for such residue, (taking into
account the time and expense necessary to obtain a replacement tenant or
tenants, including expenses hereinafter described in subparagraph (d) relating
to recovery of the Premises, preparation for reletting and for reletting itself)
which the parties agree shall in no event exceed sixty percent (60%) of the then
present value of the rent for the period, and (ii) the cost of performing any
other covenants which would have otherwise been performed by Tenant.

            (d) Upon any termination of Tenant's right to possession only
without termination of the Lease, Landlord may at Landlord's option, enter into
the Premises, remove Tenant's signs and other evidences of tenancy, and take and
hold possession thereof as provided in subparagraph (b) above, without such
entry and possession terminating the Lease or releasing Tenant, in whole or in
part, from any obligation, including Tenant's obligation to pay the rent,
including any amounts treated as additional rent hereunder for the full Term. In
any such case Tenant shall pay forthwith to Landlord, if Landlord so elects, a
sum equal to the entire amount of the rent, including any amounts treated as
additional rent hereunder, for the residue of the stated Term plus any other
sums provided herein to be paid by Tenant for the remainder of the Term.

            Landlord may, but need not, relet the Premises or any part thereof
for such rent and upon such terms as Landlord, in its sole discretion, shall
determine (including the right to relet the Premises for a greater or lesser
term than that remaining under this Lease, the right to relet the Premises as a
part of a larger area, and the right to change the character or use made of the
Premises). If Landlord decides to relet the Premises or a duty to relet is
imposed upon Landlord by law, Landlord and Tenant agree that Landlord shall only
be required to use the same efforts Landlord then uses to lease other properties
Landlord owns or manages (or if the Premises are then managed for Landlord, then
Landlord will instruct such manager to use the same efforts such manager then
uses to lease other space or properties which it owns or manages); provided,
however, that Landlord (or its manager) shall not be required to give any
preference or priority to the showing or leasing of the Premises over any other
space that Landlord (or its manager) may be leasing or have available and may
place a suitable prospective tenant in any such available space regardless of
when such alternative space becomes available; provided, further, that Landlord
shall not be required to observe any instruction given by Tenant about such
reletting or accept any tenant offered by Tenant unless such offered tenant has
a creditworthiness acceptable to Landlord, leases the entire Premises, agrees to
use the Premises in a manner consistent with the Lease and leases the Premises
at the same rent, for no more than the current Term and on the same other terms
and conditions as in this Lease without the expenditure by Landlord for tenant
improvements or broker's commissions. In any such case, Landlord may, but not
shall not be required to, make repairs, alterations and additions in or to the
Premises and redecorate the same to the extent Landlord deems necessary or
desirable, and Tenant shall, upon demand, pay the cost thereof, together with
Landlord's expenses of reletting, including, without limitation, any broker's
commission incurred by Landlord. If the consideration collected by Landlord upon
any reletting plus any sums previously collected from Tenant are not sufficient
to pay the full amount of all rent, including any amounts treated as additional
rent hereunder, and other sums reserved in this Lease for the remaining Term,
together with the cost of repairs, alterations, additions, redecorating, and
Landlord's expenses of reletting and the collection of the rent accruing the
refrom (including attorney's fees and broker's commissions), Tenant shall pay to
Landlord the amount of such deficiency upon demand and Tenant agrees that
Landlord may file suit from time to time to recover sums falling due under this
section.

            (e) Landlord may, at Landlord's option, enter into and upon the
Premises if Landlord determines in its sole discretion that Tenant is not acting
within a commercially reasonable time to maintain, repair or replace anything
for which Tenant is responsible hereunder and correct the same, without being
deemed in any manner guilty of trespass, eviction or forcible entry and detainer
and without incurring any liability for any damage resulting therefrom and
Tenant agrees to reimburse Landlord, on demand, as additional rent, for any
expenses which Landlord may incur in thus effecting compliance with Tenant's
obligations under this Lease.

            (f) Any and all property which may be removed from the Premises by
Landlord pursuant to the authority of the Lease or of law, to which Tenant is or
may be entitled, may be handled, removed and stored, as the case may be, by or
at the direction of Landlord at the risk, cost and expense of Tenant, and
Landlord shall in no event be responsible for the value, preservation or
safekeeping thereof. Tenant shall pay to Landlord, upon demand, any and all
expenses incurred in such removal and all storage charges against such property
so long as the same shall be in Landlord's possession or under Landlord's
control. Any such property of Tenant not retaken by Tenant from storage within
thirty (30) days after removal from the Premises shall, at Landlord's option, be
deemed conveyed by Tenant to Landlord under this Lease as by a bill of sale
without further payment or credit by Landlord to Tenant.

            In the event Tenant fails to pay any installment of rent, including
any amount treated as additional rent hereunder, or other sums hereunder as and
when such installment or other charge is due, Tenant shall pay to Landlord on
demand a late charge in an amount equal to five percent (5%) of such installment
or other charge overdue in any month and five percent (5%) each month thereafter
until paid in full to help defray the additional cost to Landlord for processing
such late payments, and such late charge shall be additional rent hereunder and
the failure to pay such late charge within ten (10) days after demand therefor
shall be an additional event of default
<PAGE>

hereunder. The provision for such late charge shall be in addition to all of
Landlord's other rights and remedies hereunder or at law and shall not be
construed as liquidated damages or as limiting Landlord's remedies in any
manner.

            Pursuit of any of the foregoing remedies shall not preclude pursuit
of any of the other remedies herein provided or any other remedies provided by
law (all such remedies being cumulative), nor shall pursuit of any remedy herein
provided constitute a forfeiture or waiver of any rent due to Landlord or of any
damages accruing to Landlord. No act or thing done by Landlord or its agents
during the Term shall be deemed a termination of this Lease or an acceptance of
the surrender of the Premises, and no agreement to terminate this Lease or
accept a surrender of said Premises shall be valid unless in writing signed by
Landlord. No waiver by Landlord of any violation or breach of any of the terms,
provisions and covenants herein contained shall be deemed or construed to
constitute a waiver of any other violation or breach. Landlord's acceptance of
the payment of rental or other payments hereunder after the occurrence of an
event of default shall not be construed as a waiver of such default, unless
Landlord so notifies Tenant in writing. Forbearance by Landlord in enforcing one
or more of the remedies herein provided upon an event of default shall not be
deemed or construed to constitute a waiver of such default or of Landlord's
right to enforce any such remedies with respect to such default or any
subsequent default. If, on account of any breach or default by Tenant, it shall
become necessary or appropriate for Landlord to employ or consult with an
attorney concerning or to enforce or defend any of Landlord's rights or remedies
hereunder, Tenant agrees to pay any attorney's fees so incurred.

                                  16. Mortgages

            Tenant accepts this Lease subject and subordinate to any mortgage(s)
and/or deed(s) of trust now or at any time hereafter constituting a lien or
charge upon the Premises or the Building, provided, however, that if the
mortgagee, trustee, or holder of any such mortgage or deed or trust elects to
have Tenant's interest in this Lease superior to any such instrument, then by
notice to Tenant from such mortgagee, trustee or holder, this Lease shall be
deemed superior to such lien, whether this Lease was executed before or after
said mortgage or deed of trust. Tenant shall at any time hereafter on demand
execute any instruments, releases or other documents which may be required by
any mortgagee for the purpose of evidencing the subjection and subordination of
this Lease to the lien of any such mortgage or for the purpose of evidencing the
superiority of this Lease to the lien of any such mortgage, as may be the case.

                         17. Mechanic's and Other Liens

            Tenant agrees that it will pay or cause to be paid all sums legally
due and payable by it on account of any labor performed or materials furnished
in connection with any work performed on the Premises on which any lien is or
can be validly and legally asserted against its leasehold interest in the
Premises and that it will save and hold Landlord harmless from any and all loss,
cost or expense based on or arising out of assorted claims or liens against the
leasehold estate or against the right, title and interest of the Landlord in the
Premises or under the terms of this Lease. If any such lien shall remain in
force and effect for twenty (20) days after written notice thereof from Landlord
to Tenant, Landlord shall have the right and privilege at Landlord's option of
paying and discharging the same or any portion thereof without inquiry as to the
validity thereof, and any amounts so paid, including expenses and interest,
shall be so much additional indebtedness hereunder due from Tenant to Landlord
and shall be repaid to Landlord immediately on rendition of a bill therefor.
Notwithstanding the foregoing, Tenant shall have the right to contest any such
lien in good faith and with all due diligence so long as any such contest, or
action taken in connection therewith, protects the interest of Landlord and
Landlord's mortgagee in the Premises and Landlord and any such mortgagee are, by
the expiration of said twenty (20) day period, furnished such protection, and
indemnification against any loss, cost or expense related to any such lien and
the contest thereof as are satisfactory to Landlord and any such mortgagee.

                                   18. Notices

            Any notice or document required or permitted to be delivered
hereunder shall be deemed to be delivered upon receipt if delivered personally
or by contract carrier or, whether actually received or not, when deposited in
the United States Mail, postage prepaid, Certified or Registered Mail, addressed
to the parties hereto at the respective addresses set out below, or at such
other address as they have theretofore specified by written notice delivered in
accordance herewith. If and when included within the term "Landlord" or "Tenant"
as used in this instrument, there are more than one person, firm or corporation,
all shall jointly arrange among themselves for their joint execution of such a
notice specifying some individual at some specific address for the receipt of
notices and payments. All parties included within the terms "Landlord" and
"Tenant", respectively, shall be bound by notices given in accordance with the
provisions of this paragraph to the same effect as if each had received such
notice.

                                19. Miscellaneous

            A. The terms, provisions and covenants and conditions contained in
this Lease shall apply to, inure to the benefit of, and be binding upon, the
parties hereto and upon their respective heirs, legal representatives,
successors and permitted assigns, except as otherwise herein expressly provided.
Landlord shall have the right to assign any of its rights and obligations under
this Lease and Landlord's grantee or Landlord's successor, as the case may be,
shall upon such assignment, become Landlord hereunder, thereby freeing and
relieving the grantor or assignor, as the case may be, of all covenants and
obligations of Landlord hereunder.

            B. Tenant shall at any time and from time to time within ten (10)
days after written request from Landlord execute and deliver to the Landlord or
any prospective Landlord, mortgagee or prospective mortgagee a sworn and
acknowledged estoppel certificate, in form reasonably satisfactory to Landlord
and/or such mortgagee certifying and stating accurate statements required by
Landlord or such mortgagee. It is intended that any such statement delivered
pursuant to this subsection may be relied upon by any prospective purchaser or
mortgagee and their respective successors and assigns and Tenant shall be liable
for all loss, cost or expense resulting from the failure of any sale or funding
of any loan caused by any misstatement contained in such estoppel certificate.
Tenant hereby irrevocably appoints Landlord or if Landlord is a trust,
Landlord's beneficiary, as attorney-in-fact for Tenant with full power and
authority to execute and deliver in the name of Tenant such estoppel certificate
if Tenant fails to deliver the same within such ten (10) day period and such
certificate as signed by Landlord or Landlord's beneficiary, as the case may be,
shall be fully binding on Tenant, if Tenant fails to deliver a contrary
certificate within five (5) days after receipt by Tenant of a copy of the
certificate executed by Landlord on behalf of Tenant.

            C. All obligations of Tenant hereunder not fully performed as of the
expiration or earlier termination of the Term shall survive the expiration or
earlier termination of the Term, including without limitation, all payment
obligations with respect to Taxes, Operating Costs and the like and all
obligations concerning the condition of the Premises. Upon the expiration or
earlier termination of the Term, and prior to Tenant vacating the Premises,
Landlord and Tenant shall jointly inspect the Premises and Tenant shall pay to
Landlord any amount estimated by Landlord as necessary to put the Premises,
including without limitation heating and air conditioning systems and equipment
therein, in good condition and repair. Any work required to be done by Tenant
prior to its vacation of the Premises which has not been completed upon such
vacation, may be completed by Landlord at Tenant's expense. Tenant shall also,
prior to vacating Premises, pay to Landlord the amount, as estimated by
Landlord, of Tenant's obligation hereunder for Taxes and Operating Costs. All
such amounts shall be used and held by Landlord for payment of such obligations
of Tenant hereunder, with Tenant being liable for any additional costs therefor
upon demand by Landlord, or with any excess to be returned to Tenant after all
such obligations have been determined and satisfied.

            D. All policies of insurance to be obtained by Tenant shall be
procured by Tenant from responsible insurance companies satisfactory to
Landlord. Certified copies of such policies, together with receipt evidencing
payment of premiums therefor, shall be delivered to Landlord prior to the
Commencement Date and not less than fifteen (15) days prior to the expiration
dates of such policies.

            E. Tenant's "proportionate share" as used in this Lease shall mean a
fraction, the numerator of which is the rentable area (other than any designated
parking and loading areas) contained in the Premises and the denominator of
which is the rentable area

<PAGE>

                                                     *James Mounce Inc.

contained in the Building, in each case as determined by Landlord. For purposes
hereof, the numerator is n/a and the denominator is n/a and Tenant's
proportionate share is __________ percent(___%).

            F. Tenant represents and warrants to Landlord that it has not dealt
with any broker or finder in connection with this Lease except,* and indemnifies
and holds the other harmless from any and all loss, liability, costs or expenses
(including attorney's fees) incurred as a result of any breach of the foregoing
warranty. Landlord agrees to pay the broker, if any, listed above.

            G. Neither party shall record this Lease or a memorandum hereof
without the prior written consent of the other party and the party seeking the
recording shall pay all charges and taxes incident thereto.

            H. In no event shall Landlord's liability for any breach of any
contractual obligation of this Lease exceed the amount of rental then remaining
unpaid for the then current Term (exclusive of any renewal periods which have
not then actually commenced). This provision is not intended to be a measure or
agreed amount of Landlord's liability with respect to any particular breach, and
shall not be utilized by any court or otherwise for the purpose of determining
any liability of Landlord hereunder, except only as a maximum amount not to be
exceeded in any event.

            EXECUTED the 15 day of July, 1996.

shall return the deposit (with interest earned thereon, if any) plus the net
cost of title examination and survey, if any, has been incurred by Buyer or (ii)
Buyer may elect to take such title as Seller is able to convey without any
reduction, credit or adjustment in the Purchase Price.

          C. Each party shall deliver or cause to be delivered to the other
party or to the title company such duly executed and acknowledged or verified
certificates and other instruments respecting its power and authority to perform
the obligations hereunder, the due authorization thereof by appropriate
corporate or other proceedings and the authority of the officer or other
representatives acting for such party at the Closing, as counsel for the other
party or the title company may reasonably request.

          D. If the Subject Premises shall, at the time of Closing, be subject
to any liens, such as for judgments or transfer, franchise, license or other
similar taxes, or any encumbrances or other title exceptions which would be
grounds for Buyer to reject title hereunder, Seller shall be obligated to expend
up to Five Hundred Thousand Dollars ($500,000.00) to satisfy or cure same or to
cause the Subject Premises to be released from such liens, and same shall not be
deemed an objection to title provided that, at the time of Closing, the title
company will issue or bind itself to issue a policy which will omit same as
exceptions to title or will insure buyer against collection thereof from or
enforcement thereof against the Subject Premises at no additional cost 


                                                                         Page 18

<PAGE>

to Buyer and for a premium computed at regular rates. Seller shall have no
obligation to cure non-monetary liens or encumbrances.

     12.  DESTRUCTION, DAMAGE OR CONDEMNATION.

          A. Seller shall keep in effect until Closing its present hazard
insurance. The risk of any loss by fire or other casualty or by the taking of
the Subject Premises or any part thereof by eminent domain shall be assumed
solely by Seller until Closing; provided, however, that in the event of damage
to or destruction of the Subject Premises that is not material (for the purposes
hereof, damage or destruction shall not be deemed material if the reasonably
estimated cost of restoration does not exceed Five Hundred Thousand Dollars
($500,000.00)), this Agreement shall remain in full force and effect, and Seller
shall pay over to Buyer the amount of the insurance proceeds collected to the
extent not applied to the restoration or repair of the Subject Premises or, if
any proceeds have not been collected, Seller shall assign to Buyer all its
right, title and interest in and to the same to the extent not applied by Seller
to the restoration or repair of the Subject Premises. In the event casualty
losses occur which were not insured.,Seller shall pay or credit to the Purchase
Price at the Closing an amount agreed to by Buyer and Seller to be necessary for
restoration. Seller retains the right to make any claims against the insurance
company arising out of any such casualty resulting in a credit to the Purchase
Price.

          B. If the damage or destruction to the Subject Premises is material
(the cost of restoration will exceed Five Hundred Thousand Dollars
($500,000.00)), or if any material part of the Subject Premises constituting
part of the property shall be taken by eminent domain, then


                                                                         Page 19

<PAGE>

Buyer or Seller may elect to, upon notice to the other party given not later
than ten (10) days after receipt of notice of such damage or taking, (i)
terminate this Agreement, or (ii) proceed to Closing under the same terms and
conditions as set forth herein, and, in the event of a taking, Buyer, if it
elects, in its sole discretion, to proceed, shall receive an assignment of any
awards in connection therewith. Upon termination pursuant to the preceding
sentence, the obligations of each party to the other shall terminate without
further liability hereunder or otherwise except that the Deposit (with interest
earned thereon, if any) shall be refunded by Seller and/or Escrow Agent to
Buyer.

     13.  BROKERAGE.

          Seller and Buyer represent and warrant to each other that they have
dealt with no broker in connection with this Agreement other than Corporate
National Realty, Inc. (the "Broker") and that they know of no broker who has
claimed or may have the right to claim a commission or other compensation, in
connection with this transaction other than the Broker. Seller and Buyer shall
indemnify, defend and hold each other harmless against any loss, liability,
costs, claims or expenses, including, but not limited to, reasonable attorneys'
fees and expenses, arising out of the breach on their part of any
representations, warranties or agreements contained in this Section 13. In the
event of a third-party brokerage claim made against either party, which claim,
if true, would constitute a breach of this representation, then the party
required to indemnify the other party shall defend such other party from such
claim. The representations and obligations under this Section 13 shall survive
the Closing or, if Closing does not occur, the termination of this Agreement.


                                                                         Page 20

     14.  NO MORTGAGE CONTINGENCY.

          A. This Agreement and Buyer's obligations hereunder are not subject to

whatsoever.

polychlorinated biphenyls, underground storage tanks and the contents thereof,
flammable explosives, radioactive materials, hazardous materials, hazardous
wastes, hazardous or toxic substances, or related materials, including, without
limitation, any such materials defined or regulated pursuant to (i) any federal
statute, law, rule or regulation, including, but not limited to, the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980 as
amended by the Superfund Amendments and Re-authorization Act of 1986, the
Resource Conservation and Recovery Act, (42 U.S.C. ss.6901. et seq.) and in the
regulations adopted and publications promulgated pursuant thereto, or (ii) any
state or local law, rule or regulation having jurisdiction thereof, as such laws
or regulations now exist.


                                                                         Page 22

<PAGE>

          B. Seller represents and warrants that to the best of its knowledge,
there is no environmental condition at the Subject Premises requiring the
clean-up of Hazardous Substances under applicable Federal, state and local laws,
rules and regulations and that there are no underground or above-ground fuel oil
storage tanks located at the Subject Premises, except as shown on the Phase I
Environmental Site Assessment, prepared by Geraghty & Miller. Seller's
representations and warranties set forth in this Section 16 shall survive the
Closing for a period of five (5) years.

          C. Notwithstanding anything contained in this Section 16 or this
Agreement to the contrary, it is expressly understood and agreed that Seller
shall in no event be liable to Buyer for consequential damages arising in
respect of environmental matters or claims.

     17.  CLOSING COSTS.

          Buyer shall pay the costs of examination of title and any owner's
policy of title insurance to be issued insuring Buyer's title to the Subject
Premises, any mortgagee's policy of title insurance to be issued insuring
mortgagee's mortgage encumbering the Subject Premises, if any, as all other
title charges and all other costs or expenses incident to the execution or
recordation of documents required in order to transfer title to (and mortgage)
the Subject Premises and record any document given in connection with the
conveyance (and mortgaging) of the Subject Premises, except that Seller shall
pay for all documentary stamps to be affixed to the Deed conveying the Subject
Premises in accordance with Article 31 of the Tax Law of the State of New


                                                                         Page 23


<PAGE>

York. Other than as expressly set forth herein, both parties shall bear all of
their respective costs and expenses associated with the transactions
contemplated by this Agreement.

     18.  PENDING TAX REDUCTION PROCEEDINGS

          A. Seller shall have the right to continue the tax certiorari
proceedings in respect of the Subject Premises which are currently pending for
the fiscal year 1996 and for periods prior thereto. In the event that as a
result of any such proceeding there is a real estate tax reduction which covers
a fiscal tax year a portion of which occurs from or after the Closing, Buyer
shall be entitled to its pro rata share of any such reduction, less the legal
fees and expenses in proportion to Buyer's share of the reduction.
Notwithstanding the foregoing, Seller shall suspend and adjourn any proceeding
or proceedings, if any, now pending for the reduction of the assessed valuation
of the Subject Premises for the fiscal year 1997 (the "Fiscal Year"), and at
Closing Seller shall assign any and all such proceedings to Buyer. On the
Closing Date, Seller shall deliver to Buyer copies of any applications currently
pending for such Fiscal Year, together with a substitution of counsel. The
attorneys representing Seller in connection with any such real estate tax
reduction proceedings will withdraw from representation of Seller effective on
the Closing Date free and clear of any claims for attorneys' fees.

          B. Buyer is hereby authorized to continue any such proceeding or
proceedings subsequent to Closing (as same relate to periods of time after the
Closing Date) and in Buyers sole discretion to litigate or settle same without
Seller's consent or approval.


                                                                         Page 24

<PAGE>

          C. It is further agreed between Seller and Buyer that the net refund
of taxes, if any, for such Fiscal Year received by either Seller or Buyer in any
such proceeding, shall be apportioned between Seller and Buyer, as of the
Closing Date, in the same manner as other adjustments, in accordance with the
provisions of this Agreement. Prior to any apportionment, however, Buyer shall
be entitled to deduct from any refund that it receives all expenses including
reasonable attorneys' fees incurred in obtaining such refund. Seller shall
deliver to Buyer, upon demand, receipted tax bills and cancelled checks used in
payment of such taxes and shall execute any and all consents or other documents,
and do any act or thing necessary for the collection of such refund by Buyer.
The provisions of this Section 18 shall survive the Closing.

     19.  LIQUIDATED DAMAGES.

          In the event for any reason the Buyer does not perform its obligations
hereunder by failing to close title hereunder, the parties agree that the
Deposit and any interest earned thereon shall be considered liquidated damages
and may be retained by the Seller for its sole and exclusive remedy. It is
understood that it would be impossible to ascertain the amount of damages in the
event of such default by Buyer, and therefore, the parties agree that the
Deposit together with interest earned thereon constitutes a fair and reasonable
sum to cover such damages. This in no way shall be construed as a penalty
clause.


                                                                         Page 25

<PAGE>

     20.  BUYER'S APPLICATION FOR PERMIT.

          A. Prior to the Closing Date, Buyer shall have the right to apply for
any permits for construction, alteration or other work on the Subject Premises.
Seller shall cooperate with Buyer; in connection with any such applications
including, without limitation, the execution and delivery of application or
consent forms, furnishing of documents and other information in Seller's
possession which may be reasonably required by Buyer or the agency, department
or other entity to whom such application may be made. Any such applications
shall be at Buyer's sole cost and expense and Seller shall not be obligated or
required to incur any expense or liability to third parties to comply with this
Section 20. Buyer shall not change or alter the Subject Premises or any
improvements thereon prior to the Closing Date, even if permits are issued by
the authorities having jurisdiction with respect thereto. It shall not be a
condition to Buyer's obligation to close under this Agreement that Buyer obtain
any of such permits.

     21.  MISCELLANEOUS PROVISIONS.

          A. This Agreement embodies and constitutes the entire understanding
between the parties with respect to the transaction contemplated herein, and all

Building, the improvements or personal property included therein. The Seller is
not liable or bound in any manner by any verbal or written statements,

condition, income, leases or rents furnished by any real estate broker, agent,
employee, or other person, unless the same are specifically set forth herein.

          C. The acceptance of the deed by Buyer at Closing shall be deemed to
be full performance of, and discharge of, every agreement, representation
(except those that are to expressly survive the Closing) and obligation on the
part of Seller to be performed hereunder as a condition precedent to Buyer's
obligations except for matters that are expressly provided herein or otherwise
in writing to survive the Closing.

of the successors and permitted assigns of the parties.

          G. The submission of this Agreement by Buyer or Seller shall in no

provisions of Section 1445 of the Internal Revenue Code of 1954, as amended
("Section 1445"). If Seller shall fail to furnish the same, Buyer shall comply

                                                                         Page 28

                                                                         Page 29

<PAGE>

          O. This Agreement has been drafted on the basis of mutual contribution

their own choosing, and is not to be construed against any party as being the
drafter or causing the same to be drafted.

          P. Each of Buyer and Seller shall pay its own costs and expenses
(including, without limitation, attorneys' fees and other professional fees and

writing at any time by the party which is entitled to the benefits thereof. No
waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of such provision at any time in the future or a waiver of
any other provision hereof.

          R. Notwithstanding anything to the contrary in this Agreement, (i)
nothing in this Agreement is intended to or shall create for or grant to any
third person any rights whatsoever, as a third party beneficiary or otherwise,
(ii) no third person is entitled to rely on any of the representations,
warranties, covenants or agreements contained herein; and (iii) no party hereto
shall incur any liability or obligation to any third person because of any
reliance by such third person on any representation, warranty, covenant or
agreement herein.


                                                                         Page 30

<PAGE>

          S. As used in this Agreement, the Exhibits and the Schedule as
required by the context; the singular and plural shall be deemed to include each
other an each gender, to include all genders, words importing persons shall
include partnerships, associations, corporations, trusts and other entities, the
terms "herein", "hereof", and "hereunder" or other similar terms refer to this
Agreement as a whole and not only to the particular sentence, paragraph,
subsection or section in which any term is used except as expressly more
specifically limited; and words and phrases defined in this Agreement have the
same meaning in the Exhibits and the Schedule unless specifically provided to
the contrary in any Exhibits and the Schedule. As used herein the term "party"
refers, as appropriate, to Seller or Buyer.

          T. Except with respect to the Confidentiality Agreement entered into
by and between Buyer and Seller, dated November 13, 1996, this Agreement,
including all Exhibits and the Schedule hereto, constitute the sole
understanding of the parties with respect to the matters contemplated hereby and
thereby and supersedes and renders null and void all prior agreements and
understandings between the parties with respect to such matters. No amendment
modification or alteration of the terms or provisions of this Agreement,
including all Exhibits and the Schedule hereto, shall be binding unless the same
shall be in writing and duly executed by the party to be charged with such
amendment, modification or alteration.


                                                                         Page 31

<PAGE>

          U. It is understood and agreed that all understandings,
representations and agreements heretofore had between the parties (including
their brokers and agents) hereto are merged in this Agreement, which alone fully
and completely expresses their agreement, and that the same is entered into
after full investigation neither party relying upon any statement or
representation not embodied in this Agreement, made by the other.

          V. Notwithstanding anything contained herein to the contrary, if this
transaction shall not close solely as a result of a willful default by Seller
under this Agreement, then the Deposit with interest earned on the Deposit,
shall be returned by Escrow Agent to Buyer within five (5) days following demand
by Buyer. In the event that Seller willfully fails to perform any of its
obligations under this Agreement, in addition to the return of the Deposit and
interest as above provided, Buyer shall have the right to seek specific
performance of this Agreement. In the event buyer prevails in such specific
performance action, Buyer shall be obligated to pay to Seller the full Purchase
Price including the amount of the Deposit, less cost and expenses of enforcing
rights including, but not limited to, legal fees and expenses. In no event shall
Buyer have the right to seek damages from Seller as a result of any default or
breach by Seller under this Agreement. Seller's inability to close (e.g., due to
title defects which Seller is not obligated to cure) shall not be deemed a
willful default.


                                                                         Page 32

<PAGE>

          W. Except in the event of a willful default by Seller, Buyer shall not
record this Agreement or a memorandum of this Agreement. Any such recording by
Buyer shall be deemed a material default hereunder entitling Seller to terminate
this Agreement and retain the Deposit and interest as liquidated damages.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date first above written.
