                                  THE COMPANY
 
    The Company provides advanced communications solutions to customers with
operations in remote, difficult-access regions and in areas around the world
where government deregulation has created new market opportunities. The Company
delivers comprehensive communications services to its customers by utilizing a
broad range of analog and digital technologies, including satellite, microwave
radio, conventional two-way radio and fiber optic cable. The Company's core
business to date has focused on the provision of communications solutions for
customers in the oil and gas industry, such as AMOCO, British Gas, Chevron,
Conoco, Exxon and Shell. Such customers exemplify users with unique
communications needs related to the remote, difficult-access nature of their
operating locations. By providing a wide range of communications solutions to
its oil and gas customers, the Company has developed a high level of expertise
and a unique skill set in planning, designing and implementing total
communications solutions for multi-site customers with operations located in
remote regions or underdeveloped areas where the existing communications
infrastructure is insufficient to meet advanced telecommunications needs. The
Company intends to leverage this skill set and expertise by supplying
communications services to multi-site customers outside of the oil and gas
industry, particularly customers with operations located near the Company's
existing and planned telecommunications infrastructure. Potential additional
customers include health care providers, financial institutions and other
multi-location communication-intensive companies, such as large publishing
companies.
 
    The Company recently has installed a tandem switch and a value-added
services platform in Houston, Texas. This switch and platform enable the Company
to connect its digital network with the networks of other carriers, thereby
permitting the routing of phone calls in a cost-competitive manner. As the
Company's communications network in the Gulf Coast expands, the Company intends
to install additional switches in other strategic locations. The Company
recently has received approval to serve as a competitive local exchange carrier
("CLEC") in select locations in Texas and has applied for CLEC status in
Louisiana. As a result, the Company believes that it is well positioned to use
the full capacity of its existing and planned infrastructure by providing call
routing to other carriers and, in select locations, by providing call completion
services at profit margins that the Company believes will be higher than those
achievable without CLEC status. As a CLEC offering competitive rates for call
completion services, the Company expects that cellular, personal communications
services ("PCS") and other long distance carriers will become additional
customers.
 
    The telecom services industry is being transformed by the deregulation of
telecommunications markets around the world. In the United States, efforts at
deregulating the telecommunications industry resulted in the separation of the
long distance market from the local exchange services market, with the outcome
being an opening of the long distance market to competition. The enactment of
the Telecommunications Act of 1996 (the "1996 Telecommunications Act")
established an expansive framework for greater competition, including within the
local exchange services market. Under the 1996 Telecommunications Act, state
laws prohibiting competition are preempted and CLECs, such as the Company, have
legal rights to interconnect with the facilities of the Bell Operating Companies
("BOCs") and GTE Operating Companies ("GTOCs"), resell local services that were
previously provided only by the BOCs and GTOCs, and deliver CLEC-provided local
services as well as long distance services. Telecommunications revenues of CLECs
grew almost 80% in 1996 to $2.1 billion, compared with nearly $1.2 billion in
1995, according to
 
                                       3
<PAGE>
the 8th Edition of the ANNUAL REPORT ON THE COMPETITIVE TELECOMMUNICATIONS
INDUSTRY. International deregulation has also gained momentum, as demonstrated
by the recent 68-nation World Trade Organization agreement on communications
services, which reflects efforts to dismantle government-owned
telecommunications monopolies throughout Europe, Asia and India.
 
    The introduction and proliferation of new communications technologies,
together with global socioeconomic development, are also contributing to
significant increases in demand for telecommunications services throughout the
world. Advances in communications delivery technology, including those achieved
through the deployment of satellite systems and the development of data
compression technologies, have expanded the variety of information that can be
digitized as well as the geographic scope of where such data may be transmitted
or received. Political and economic changes in many regions of the world have
contributed to the emergence of additional global market opportunities in a
variety of industries and an increased rate of adoption of Western business
practices in previously non-Westernized areas. The Company believes that these
changes have escalated the demand for Western telecommunications services,
particularly in remote regions of the world or in regions where the
telecommunications infrastructure is underdeveloped.
 
    While the demand for telecommunications services is increasing worldwide,
the Company believes that the exploration and development activities
characteristic of the oil and gas industry have placed that industry, in
particular, at the forefront in applying modern communications technologies in
remote regions of the world or regions that lack developed telecommunications
infrastructure. The Company also believes that numerous other industries are
taking advantage of technological advances and socioeconomic development by
pursuing opportunities to expand their operations into remote regions or areas
with underdeveloped telecommunications infrastructure. Following the
installation of additional infrastructure in such regions, the local communities
in such regions may be able to make use of the available extra carrier capacity,
even though such additional infrastructure might have been installed originally
as a specific communications solution for a particular company or end-user. The
Company believes that a significant opportunity exists to provide advanced
communications services to end-users outside the oil and gas industry by
delivering effective temporary or permanent solutions at competitive rates and,
in doing so, the Company intends to position itself to serve the
telecommunications carrier service needs of neighboring communities and
businesses.
 
    The Company's goal is to become a leading provider of total communications
solutions to end-users with operations in remote, difficult-access regions or in
areas around the world where government deregulation has created new market
opportunities and to leverage this position by providing carrier services to
additional customers located in these same regions. To reach this goal, the
Company intends to pursue the following strategies: (i) develop additional
Company-owned infrastructure; (ii) vertically integrate service offerings; (iii)
diversify its customer base; (iv) capitalize on opportunities created by
government deregulation and globalization trends in various industries; and (v)
expand existing strategic alliances and establish new alliances.
 
    The Company commenced doing business as IWL Communications in 1981 and was
incorporated as a Texas corporation in 1983. The Company currently has domestic
branch offices in Houston and Friendswood, Texas and Lafayette and New Orleans,
Louisiana and an international office in Moscow, Russia. The Company's principal
executive office is located at 12000 Aerospace Avenue, Suite 200, Houston,
Texas, 77034 and its telephone number is (281) 482-0289. The Company's Internet

    AN INVESTMENT IN THE SHARES OF COMMON STOCK, PAR VALUE $.01 PER SHARE (THE
"COMMON STOCK"), OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK. IN ADDITION TO
THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS, PROSPECTIVE INVESTORS SHOULD
CONSIDER CAREFULLY THE FOLLOWING RISK FACTORS IN EVALUATING THE COMPANY AND ITS
BUSINESS BEFORE PURCHASING THE SHARES OF COMMON STOCK OFFERED HEREBY. THIS
PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS,
INCLUDING THOSE SET FORTH IN THE FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS
PROSPECTUS.
 
INDUSTRY CONCENTRATION AND DEPENDENCE ON MAJOR CUSTOMERS
 
    Customers in the oil and gas industry accounted for substantially all of the
Company's sales in its fiscal years ended June 30, 1995 and 1996. The Company's
business and results of operations are substantially dependent on sales to oil
and gas customers, and the loss of one or more of these customers, or a
significant reduction in sales to them, could have a material adverse effect on
the Company's financial condition, results of operations and cash flow. The
Company currently is attempting to broaden its customer base into other
industries besides the oil and gas industry; however, there can be no assurance
that the Company will be successful in doing so. Currently, the Company's
operations could be significantly impacted by market forces affecting the the
oil and gas industry as a whole. There can be no assurance that the oil and gas
industry will not suffer a significant downturn, nor can there be any assurance
that the Company will remain profitable when operating under such conditions.
Product resales by the Company to Shell Offshore Services Company ("Shell"), a
subsidiary of Shell Oil Company, were approximately $10.6 million and $4.7
million for the year ended June 30, 1996 and for the six months ended December
31, 1996, representing approximately 38% and 30%, respectively, of total sales
during such periods. These resales were made in connection with a one-time
project for Shell, which includes a significant equipment resale component, that
the Company expects will be substantially completed in fiscal 1997 and,
therefore, is not expected to contribute in a material manner to the Company's
total sales in future periods. While the Company performs other services for
Shell and its affiliates from time-to-time on a project-by-project basis, the
Company expects that future sales to Shell and its affiliates will be less than
sales in fiscal 1996. If sales to Shell and its affiliates decline and are not
replaced by additional sales to other customers, then the Company's sales will
be materially reduced. A loss of Shell and its affiliates as a customer, or a
significant reduction in sales to Shell and its affiliates, could have a
material adverse effect on the Company's financial condition, results of
operation and cash flow. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business--IWL Strategy" and
"--Selected Customers."
 
COMPETITION
 
    The nature of the Company's competition is diverse due to the breadth of the
services offered by the Company and the geographic regions in which such
services are provided. The Company is subject to intense competition with
respect to each of its individual service offerings. Many of the Company's
competitors have significantly greater financial, technical, manufacturing,
personnel and marketing resources than the Company. To date, however, the
Company believes that these large competitors generally have not made it a
priority to provide telecommunications services in remote, difficult-access
regions. Should one or more of such companies focus on such services, it would
likely have a material adverse effect on the financial condition, results of
operations and cash flow of the Company. Currently, the Company believes it
competes directly with Autocomm Communications Engineering Corp., Sola
Communications, Inc. and Datacom for the sale of telecommunications services to
oil and gas companies in the Gulf of Mexico. The Company believes that its
ability to compete in the markets in which it operates depends on such factors
as reputation, technical expertise, quality, customer service, knowledge of the
business, ease of use, reliability, marketing and distribution channels and the
array of services and products
 
                                       6
<PAGE>
that it can provide. Although the Company believes that it competes favorably
with respect to these factors, there can be no assurance that the Company will
be able to compete successfully in the future. As the Company pursues new
markets, the Company likely will encounter new competitors. While the recent
World Trade Organization agreement on communications services may result in
regulatory changes that could benefit the Company as it competes in existing
markets, or seeks to enter new markets, there can be no assurance that the
agreement will be implemented in a manner that would benefit the Company or that
the pro-competitive effects of the agreement will not increase the amount of
competition encountered by the Company.
 
    DOMESTIC AND INTERNATIONAL LONG DISTANCE.  The Company provides long
distance carrier services both domestically and internationally, which it has
been marketing as a switchless reseller since 1994 and which the Company intends
to provide as a facilities-based carrier beginning in the fourth quarter of its
1997 fiscal year. The long distance markets are characterized by intense
competition with a number of companies, including very large companies such as
AT&T Corp. ("AT&T"), MCI Communications Corporation ("MCI") and Sprint
Corporation ("Sprint"), that have greater name recognition and greater
financial, technical, network and marketing resources than the Company. In
addition, as a result of the Telecommunications Act of 1996 (the "1996
Telecommunications Act"), the Bell Operating Companies ("BOCs") and the GTE
Operating Companies ("GTOCs") are able to enter the long distance market.
 
    LOCAL EXCHANGE SERVICE.  The Company is expanding its operations to provide
local exchange services typically provided by local exchange carriers ("LECs").
The local service market has only recently been opened to new service providers
following enactment of the 1996 Telecommunications Act; however, the competition
for this market is likely to be as intense as competition for the long distance
market. The services offered by the Company will compete with those offered by
LECs, such as BellSouth and Southwestern Bell and their affiliates, which
currently dominate the provision of local services in their respective markets.
If LECs lower their rates, other telecommunications providers may be forced by
market conditions to charge less for their services in order to compete, which
could have a material adverse effect on the Company's financial condition,
results of operations and cash flow. The Company also may face competition in
the provision of local telecommunications services from cable companies,
electric utilities, LECs operating outside their current local service areas,
long distance carriers and start-up telecommunications ventures. There can be no
assurance that the Company will be able to compete effectively in the local
service markets.
 
    INTERNATIONAL AND FOREIGN MARKET SERVICES.  The Company offers
telecommunications service to and from remote and difficult-access locations
outside of the United States for its customers. Such services include the
provision of telecommunications services between domestic corporate offices and
remote sites. Therefore, the Company has not competed in a full range of
services with the incumbent telecommunications providers in a particular country
and has faced competition from international telecommunications providers
generally and others who provide telecommunications services to remote and
difficult-access locations. The Company provides private-line telecommunications
services in Russia. In Russia, the major competitors for networks are SOVAMTEL,
ROSTELECOM, AMRUSCOM and Global One. Additionally, to the extent other foreign
markets are identified by the Company, they also may be identified by other
companies with significantly greater financial and other resources than the
Company. As a result, there can be no assurance that the Company will be able to
compete effectively in these markets. See "Business--Strategic Relationships and
Alliances" and "--Competition."
 
RISKS ASSOCIATED WITH ENTRY INTO LOCAL PHONE SERVICE MARKET AND OTHER NEW
  MARKETS
 
    The Company's strategy includes developing new service offerings for
specific new markets and pursuing new markets for its existing services. Entry
into new markets entails a number of risks, including those associated with the
state of development of the market, intense competition from companies already
operating in those markets, potential competition from companies that may have
greater resources than
 
                                       7
<PAGE>
the Company and increased selling and marketing expenses. In addition, to the
extent the markets are outside the United States, the Company will be subject to
the risks associated with international operations.
 
    The Company currently is developing a telecommunications network to provide
an alternative to the resale of long distance service and to provide LEC
services in selected areas along the Louisiana and Texas Gulf Coast region,
which may involve, among other things, acquiring or leasing switches and
dedicated transmission lines. The network will enable the Company, as a
switched-based carrier, to provide long distance service to its customers
directly instead of reselling other carriers' services. Notwithstanding the
Company's development of its network, the Company will remain dependent to a
large degree on the networks of other carriers for long distance services;
however, operation of a switch will enable the Company to route its customers'
calls in a more cost-effective manner. There can be no assurance that the
Company's development of a telecommunications network in the Gulf Coast region
will be completed or, if completed, will be profitable. In acquiring or leasing
the switches, dedicated transmission lines and microwave radios needed to
develop a telecommunications network, the Company may incur high levels of
indebtedness and fixed operating costs. The Company has no prior experience
operating as a switch-based carrier.
 
    The Company, which recently has been approved as a competitive local
exchange carrier ("CLEC") in Texas and has applied for CLEC status in Louisiana,
intends to offer LEC services in selected markets. Competition for local
services is at an early stage. It is difficult to determine how this market will
develop due to many factors including regulatory changes, resistance from
incumbent LECs, its market acceptance as a CLEC and competition from other
CLECs. In entering the local services market, the Company initially intends to
serve as a reseller of LEC services as permitted under the 1996
Telecommunications Act, which allows it to purchase such services at a discount
and then resell them to the public. However, the Company intends to reduce its
reliance on LECs for those services by developing its own network and installing
one or more end-office switches. Other than its experience in the Gulf of
Mexico, the Company has no experience operating as a CLEC. The Company's success
will depend, in part, on its ability to manage and integrate the operations of a
telecommunications network into the Company's existing operations, including the
development of the Company's management information systems. Such success also
will depend upon the Company's ability to resell the additional capacity that
will be available on its network. There can be no assurance that the Company's
provision of LEC services will receive market acceptance in a timely manner, or
at all, or that the Company's LEC services will be profitable. The Company's
success in the provision of CLEC services is also highly dependent on the pace
and phase of implementation of the pro-competitive provisions of the 1996
Telecommunications Act by federal and state regulatory authorities. The
Company's entry into the local phone service market, and the Company's operation
as a switch-based carrier, could have a material adverse effect on the Company's
financial condition, results of operations and cash flow. There can be no
assurance that the Company will be successful in operating as a CLEC nor can any
assurance be given with respect to its operation as a switch-based long distance
carrier if and when it develops its own network. See "--Risks Associated with
International Operations" and "Business--IWL Strategy" and "--Service
Offerings."
 
GOVERNMENT REGULATION
 
    The Company and the equipment it installs are subject to varying degrees of
federal, state and local regulation relating to wireless, long distance and
local access telecommunications services. The Company holds various radio
station authorizations that are subject to licensing, operational and technical
requirements imposed on commercial and private mobile radio services, fixed
microwave services and satellite radio earth station services. In the United
States, the provision of the Company's services is subject to the provisions of
the Communications Act of 1934, as amended (the "1934 Communications Act"), the
1996 Telecommunications Act and the regulations of the Federal Communications
Commission (the "FCC") thereunder, as well as the applicable laws and
regulations of the various states administered by the relevant
 
                                       8
<PAGE>
state public service commissions ("PSCs"). The recent trend in the United
States, for both federal and state regulation of telecommunications services
providers, has been in the direction of reduced regulation. Although this trend
facilitates market entry and competition by multiple providers, it has also
given AT&T, the largest international and domestic long distance carrier in the
United States, as well as other large long distance providers, increased pricing
and market entry flexibility that has permitted them to compete more effectively
with smaller carriers such as the Company, as well as the opportunity to
re-enter the local telephone service market. There can be no assurance that
future regulatory, judicial and legislative changes in the United States will
not have a material adverse effect on the financial condition, results of
operations and cash flow of the Company. Further, any failure by the Company to
maintain proper federal and state tariffs or certification or any finding by
federal or state agencies that the Company is not operating under permissible
terms and conditions may result in an enforcement action or investigation by the
FCC or a PSC, either of which could have a material adverse effect on the
financial condition, results of operations and cash flow of the Company.
 
    The 1996 Telecommunications Act has significantly altered regulation of the
telecommunications industry by preempting a number of state and local laws
inhibiting competition and by imposing a variety of new duties on incumbent LECs
in order to promote competition in local exchange and access services. The 1996
Telecommunications Act also eliminates previous prohibitions on the provision of
long distance services by the BOCs and GTOCs and opens up local telephone
service to long distance companies. Although the Company believes that the
enactment of the 1996 Telecommunications Act and other trends in federal and
state legislation and regulation that favor increased competition create new
opportunities for the Company, there can be no assurance that the resulting
increased competitive opportunities or other changes in current or future
regulations at the federal or state level will not have a material adverse
effect on the financial condition, results of operations and cash flow of the
Company. Furthermore, there can be no assurance of how the 1996
Telecommunications Act will be implemented or enforced or the effect it will
have on competition within the telecommunications industry generally or on the
competitive position of the Company specifically.
 
    The Company also holds authority from the FCC to provide international
services. The FCC's rules applicable to the provision of international services
may limit, under certain conditions, the size of investments in the Company by,
and affiliations with, foreign telecommunications carriers. In addition, because
the Company holds several common carrier radio licenses, the 1934 Communications
Act limits ownership of the Company by non-U.S. citizens, foreign governments
and corporations organized under the laws of a foreign country. If the Company's
foreign ownership were to exceed the limit set forth in the 1934 Communications
Act, the FCC could impose a range of penalties on the Company, including fines
or revocation or divestiture of its licenses. The Company's operations also will
be affected by introduction of new cellular services and the future allocations
and auctions of the radio frequency spectrum for such services, which may
increase competition as well as affect the type of services or products that can
be installed or offered. Regulatory changes, whether domestic or international,
may be affected by political, economic and technical factors and could
significantly impact the Company's operations in numerous ways, including by
creating greater competition, imposing new limits on services, making current
communication systems obsolete and increasing the opportunities for competition.
In addition, each country where the Company provides telecommunications services
has its own laws and regulations. In certain locations, disputes may arise as to
which country's laws and regulations apply. In many instances foreign
jurisdictions require governmental or other regulatory approval for the
equipment that the Company intends to install and the services that it intends
to provide. There can be no assurance that the Company will be able to obtain
such approvals or that it will obtain such approvals without significant delay
or expense. The delays inherent in this approval process may cause the
cancellation, postponement or rescheduling of the installation of communications
systems for the Company's customers, which in turn may have a material adverse
effect on the financial condition, results of operations and cash flow of the
Company. See "Business--Government Regulation."

VARIABILITY IN OPERATING RESULTS
 
    The Company's annual and quarterly operating results have varied
significantly in the past and are expected to vary significantly in the future.
These fluctuations in operating results generally are caused by a number of
factors, including changes in the Company's services and product mix, levels of
product resales, adverse weather conditions in customer locations, the degree to
which the Company encounters competition in its existing or target markets,
general economic conditions, the volume and timing of orders received during the
period, sales and marketing expenses related to entering new markets, the timing
of new product or service introductions by the Company or its competitors and
changes in billing rates by the Company or its competitors. Any of these factors
could cause future quarterly or fiscal year operating results to vary
significantly from the prior period and, because of the possibility of these
fluctuations, results for any particular quarter or fiscal year should not be
relied upon as being indicative of future performance. In addition, the
Company's total sales increased to $27.8 million in fiscal 1996 from $15.8
million in fiscal 1995, due primarily to product resales that were made as part
of a one-time project for Shell. The Company expects that this project will be
substantially completed in fiscal 1997. As a result, while the Company performs
other services for Shell and its affiliates from time-to-time on a project-by-
project basis, the Company expects that future sales to Shell and its affiliates
will be less than the fiscal 1996 level. See "--Industry Concentration and
Dependence on Major Customers" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
RELIANCE ON THIRD PARTIES
 
    The Company purchases substantially all of its telecommunications equipment
for use in the oil and gas industry from Alcatel Network Systems, Inc.
("Alcatel") pursuant to an agreement that generally requires the Company to use
Alcatel equipment in sales to customers in the U.S. oil and gas industry. This
requirement may limit the ability of the Company to effectively compete for
certain sales or reduce the profitability that could otherwise be obtained by
the Company from such sales. The Alcatel agreement expired on December 31, 1996;
however, the parties have continued to abide by the terms of the Alcatel
agreement while negotiating the terms of a new agreement, which the parties
expect will be substantially similar to the old agreement. The Company does not
manufacture, nor does it have the ability to manufacture, the telecommunications
equipment used by the Company in performing its services. Therefore, any
reduction or interruption in the supply of equipment from Alcatel, or any
increase in pricing by Alcatel that cannot be passed through to customers, could
have a material adverse effect on the Company's financial condition, results of
operations and cash flow until sufficient alternative supply sources are
established. Although there are other manufacturers who have, or are developing,
equipment that would satisfy the Company's needs, there can be no assurance that
the Company would be able to replace its current primary supplier on
commercially reasonable terms or on terms as favorable as those contained in the
Alcatel agreement or without a significant disruption of service or business.
See "Business--Strategic Relationships and Alliances."
 
    In an attempt to make its service more accessible to potential customers,
the Company has entered into contracts with the owners of over fifty drilling
rigs in the Gulf of Mexico whereby the Company's equipment is installed on the
drilling rigs regardless of who leases such rigs for exploration and drilling
purposes. Although such arrangements support the selection of the Company for
the rig's telecommunications services, such arrangements make the Company
dependent upon the drilling rig owner to keep the drilling rig fully leased. If
the drilling rig is not in operation, such equipment will generate limited
revenue for the Company and will not be available for use with other customers.
The failure of such rigs to operate could have a material adverse effect upon
the Company's financial condition, results of operations and cash flow.

SIGNIFICANT CAPITAL REQUIREMENTS
 
    The expansion of the Company's telecommunications operations and the
continued funding of operating expenses will require substantial capital
investment. Additionally, as part of its strategy, the Company may seek to
acquire complementary assets or businesses, including additional spectrum
licenses, which also could require substantial capital investment. The Company's
decision to accelerate the development of its carrier services in response to
the 1996 Telecommunications Act has substantially increased the Company's
capital expenditure requirements. The Company anticipates that, based on current
plans and assumptions relating to its operations, upon completion of the
Offering its financial resources and equipment financing arrangements will be
sufficient to fund the Company's growth and operations for approximately twelve
months from the date of this Prospectus. The Company believes that its capital
needs at the end of such period will continue to be significant and thus the
Company will continue to seek additional sources of capital. Further, in the
event the Company's plans or assumptions change or prove to be inaccurate, or if
the Company consummates any unplanned acquisitions of businesses or assets, the
Company may be required to seek additional sources of capital sooner than
currently anticipated. There can be no assurance that the Company will be able
to obtain additional financing or, if such financing is available, that the
Company will be able to obtain it on acceptable terms. Failure to obtain
additional financing, if needed, could result in the delay or abandonment of
some or all of the Company's development and expansion plans, which would have a
material adverse effect on the Company's financial condition, results of
operations and cash flow. See "Use of Proceeds" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview" and "--
Liquidity and Capital Resources."
 
MANAGING CHANGE
 
    The Company recently has experienced a period of significant growth and
expansion that has placed, and if sustained would continue to place, a
significant strain on its resources. This growth has resulted in an increase in
the level of responsibility for management personnel. The Company's officers
have had limited experience in managing companies as large and rapidly changing
as the Company. The Company's ability to manage change successfully will require
such personnel to work together effectively and will require the Company to
improve its operational, management, financial and information systems and
controls. If the Company's management is unable to manage change effectively,
the Company's financial condition, results of operations and cash flow could be
materially and adversely affected. See "Management."
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company is substantially dependent upon certain of its officers,
including Ignatius W. Leonards, its Chairman and Chief Executive Officer, Byron
M. Allen, its President, and Richard H. Roberson, its Chief Financial Officer.
The Company's future success depends on the continued contributions of such
officers, including the maintenance, enhancement and establishment of key
customer relationships and the management of operations and financial control.
The loss of any of these officers by the Company could have a material adverse
effect on the Company's financial condition, results of operations and cash
flow. The Company is dependent in large part on its ability to attract and
retain management, engineering, marketing and other technical personnel.
Competition for engineering and other technical personnel is intense, and the
inability to attract and retain highly qualified technical personnel to
coordinate the Company's operations could adversely affect the Company's
operations and prospects in related markets. There can be no assurance that the
Company will be able to attract and retain the qualified personnel necessary for
its business. See "Business--Employees" and "Management--Directors and Executive
Officers."

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
    A portion of the Company's sales to date have been made to customers located
outside of the United States, including customers located in Moscow, Russia and
Quito, Ecuador. International sales may account for a larger portion of the
Company's sales in the foreseeable future. Risks inherent in the Company's
international business activities include changes in regulatory requirements,
costs and risks of localizing systems in foreign countries, availability of
suitable export financing, timing and availability of export licenses, tariffs
and other trade barriers, customs matters, longer payment cycles, higher tax
rates or additional withholding requirements, difficulty in enforcing
agreements, military, political and transportation obstacles, political,
economic and religious instability, difficulties in staffing and managing
foreign operations, the burden of complying with a wide variety of complex
foreign laws and treaties and difficulty in accounts receivable collections. In
addition, foreign operations involve uncertainties arising from local business
practices, language differences, cultural considerations and international
political and trade tensions. Some of the Company's customer purchase agreements
are governed by foreign laws, which may differ significantly from U.S. laws.
Therefore, the Company may be limited in its ability to enforce its rights under
such agreements and to collect damages, if awarded. The provision of service in
foreign countries will subject the Company to a variety of laws and regulations.
These laws and regulations vary from country to country and are subject to
change. Foreign laws could prohibit, limit, impose conditions or create
competition to the Company's services. While the recent 68-nation World Trade
Organization agreement on communications services may lessen regulatory
restrictions on the Company's ability to compete in foreign countries, it may
also increase the opportunities in these countries available to the Company's
competitors. There can be no assurance that any of these factors will not have a
material adverse effect on the Company's financial condition, results of
operations and cash flow. Currently, the Company's international sales are
denominated in United States currencies. The Company does not currently engage
in foreign currency hedging transactions. The Company may be required in the
future to denominate international sales in foreign currencies. In such event, a
decrease in the value of foreign currencies relative to the United States dollar
could result in losses from transactions denominated in foreign currencies and,
with respect to the Company's international sales that are United States
dollar-denominated, such a decrease could make the Company's services less
price-competitive. In the future, the Company may seek to implement hedging
techniques with respect to foreign currency transactions. There can be no
assurance, however, that such hedging activities would successfully protect
against foreign currency exchange losses or against other international sales
risks such as exchange limitations, price controls or other foreign currency
restrictions.
 
    The Company's headquarters and administrative offices are in Houston, Texas.
In addition, as of December 31, 1996, the Company maintained an office in
Moscow, Russia with approximately 10 employees. The geographical distance
between Houston, Texas and Moscow, Russia, as well as time-zone differences, can
isolate management from operational issues, delay communications and require a
significant amount of time, effort and expense for international travel. There
can be no assurance that the Company will not face significant management
demands associated with its international operations in the future. Any
significant disruption in the management of the Company's international
operations could have a material adverse effect on the Company's financial
condition, results of operations and cash flow. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
RELIANCE ON OTHER TELECOMMUNICATIONS CARRIERS
 
    The Company depends primarily on other long distance carriers for the
transmission of long distance telephone calls. Although the Company believes its
relations with its carriers are good, the termination of the Company's contracts
with its carriers or a reduction in their services could have a material adverse
effect on the Company's financial condition, results of operations and cash
flow. In addition, the accurate and prompt billing of the Company's subscribers
is dependent upon such carriers providing accurate and timely call detail
records to third-party billing companies who bill the Company's services. There
can be no
 
                                       12
<PAGE>
assurance that the Company's current long distance carriers will provide
accurate information on a timely basis, or that the third-party billing
companies will accurately bill the Company's customers, the failure of which
could have a material adverse effect on the Company's financial condition,
results of operations and cash flow. As a reseller of LEC services, the Company
will be dependent upon the LEC for such service and the rates which will be
charged. The 1996 Telecommunications Act provides that LECs will be required to
sell their service at a discount to CLECs as established by federal and state
regulatory authority. The Company's dependence upon the LECs will be impacted by
a number of factors including regulatory changes, resistance from incumbent
LECs, its market acceptance as a CLEC and competition from other CLECs. See
"Business--Government Regulation."
 
CHANGES IN TECHNOLOGY, SERVICES AND INDUSTRY STANDARDS
 
    The telecommunications industry has been characterized by rapid
technological change, changing end-user requirements, frequent new service
introductions and evolving industry standards. The Company believes that its
future success will depend on its ability to anticipate and adapt to such
changes and to offer, on a timely basis, services that meet these evolving
industry standards. There can be no assurance that existing, proposed or as yet
undeveloped technologies will not become dominant in the future and render the
Company's systems less competitive or less viable. There can be no assurance
that the Company will have sufficient resources to make the investments
necessary to acquire new technologies or to introduce new services that could
compete with future technologies or that equipment held by the Company in
inventory will not be rendered obsolete, any of which factors could have a
material adverse effect on the Company's financial condition, results of
operations and cash flow.
 
DEPENDENCE ON INFORMATION SYSTEMS
 
    The Company currently depends upon third-party billing companies to bill the
Company's customers for their long distance usage. As the Company implements its
strategy to develop a network and to provide LEC services, the Company may begin
to bill its customers itself. In such case, the Company's information systems
will become more and more important as maintaining sophisticated and reliable
transaction processing systems is essential for a communications company. To
promptly and accurately bill its customers, the Company must record and process
massive amounts of data quickly and accurately. The Company is in the process of
evaluating and updating its information systems. However, the Company does not
have extensive experience in implementing and operating such systems. The
Company believes that the continued enhancement of its information systems is
important to its continued growth and its ability to monitor and control costs,
but there can be no assurance that the Company will not encounter delays or
suffer adverse consequences in implementing the enhanced systems. Any such delay
or other malfunction of the Company's management information systems could have
a material adverse effect on the Company's financial condition, results of
operations and cash flow.
 
POSSIBLE SERVICE INTERRUPTIONS; NATURAL DISASTERS
 
    The Company's operations are dependent on its ability to protect the
equipment it owns, and the ability of third parties to protect the equipment the
Company leases from them, against damage that may be caused by fire, equipment
failures, weather, power loss, telecommunications failures, failure or loss of
satellites, human error, unauthorized intrusion, natural disasters or
occurrences, acts of sabotage and other similar events. The Company's operations
in remote and underdeveloped areas of the world make its operations, equipment
and employees susceptible to environmental extremes and political instability.
There can be no assurance that fire, equipment failure or other events would not
disable the Company's equipment, which could have a material adverse effect on
the Company's financial condition, results of operations and cash flow. Also,
networks and switching facilities experience periodic service interruptions and
equipment failures, and the operation of such networks will be subject to
international, national and regional telecommunications outages from time to
time. It is therefore possible that the networks and
 
                                       13
<PAGE>
facilities utilized by the Company may from time to time experience service
interruptions or equipment failures that could have a material adverse effect on
the Company's financial condition, results of operations and cash flow.
Additionally, many of the Company's customers with offshore locations will
abandon facilities during the pendency of severe weather, such as hurricanes,
tropical storms and other dangerous natural forces, which results in a cessation
in the provision of services by the Company until normal operations are resumed.
Similarly, the Company's pay telephones located on customers' drilling rigs and
production platforms may experience interruptions or cessation of use due to
weather conditions or other natural occurrences, such as earthquakes or floods,
which are beyond the Company's control. A significant portion of the Company's
facilities, as well as a significant portion of its customers, are located in
the Louisiana and Texas Gulf Coast region, which is particularly susceptible to
hurricanes. Although the Company has taken precautions to protect itself and its
customers from events that could interrupt the delivery of the Company's
services, there can be no assurance that a fire, telecommunications failure,
human error, natural disaster, act of sabotage or other similar event would not
cause a disruption in the Company's services and that such events will not have
a material adverse effect on the Company's financial condition, results of
operations and cash flow.
 
CONCENTRATION OF OWNERSHIP
 
    Upon consummation of the Offering, Ignatius W. Leonards, the Company's Chief
Executive Officer and Chairman of the Board of Directors, will beneficially own
an aggregate of approximately 58% of the outstanding shares of Common Stock (or
approximately 55% if the Underwriters' over-allotment option is exercised in
full) and Mr. Leonards, together with Byron M. Allen, the President of the
Company, will beneficially own an aggregate of approximately 64% of the
outstanding shares of Common Stock (or approximately 61% if the Underwriters'
over-allotment option is exercised in full). As a result of this stock ownership
and their respective positions with the Company, Mr. Leonards, acting alone, and
Messrs. Leonards and Allen, acting together, will be in a position to control
the affairs of the Company through the ability to influence the outcome of
matters submitted to a vote of the shareholders of the Company, including the
election of directors, and matters on which the Board of Directors may act. See
"Certain Transactions" and "Principal Shareholders".
 
PROPRIETARY RIGHTS
 
    The Company believes that the future success of its business will depend
more on the technical competence, creativity and marketing abilities of its
employees than on patents, trademarks and other intellectual property rights.
Nevertheless, the Company attempts to protect its intellectual property rights
through patents, trademarks, trade secrets and other measures. The Company
currently does not own any patents, but has one patent application on file with
the U.S. Patent and Trademark Office. There can be no assurance that such
measures will provide adequate protection for the Company's trade secrets or
other proprietary information, that disputes with respect to the ownership of
its intellectual property rights will not arise, that the Company's trade
secrets or proprietary technology will not otherwise become known or be
independently developed by competitors or that the Company can otherwise
meaningfully protect its intellectual property rights. In addition, there can be
no assurance that foreign intellectual property laws will adequately protect the
Company's intellectual property rights, if any, in other countries. Litigation
may be necessary to protect the Company's intellectual property rights and trade
secrets, which could result in substantial costs and diversion of resources and
may ultimately prove unsuccessful. The failure of the Company to protect its
proprietary rights could have a material adverse effect on its financial
condition, results of operations and cash flow. If any claims or actions are
asserted against the Company, the Company may seek to obtain a license under a
third party's intellectual property rights; however, there can be no assurance
that a license will be available on commercially reasonable terms or at all.

CERTAIN ANTI-TAKEOVER MATTERS
 
    Upon the consummation of the Offering, there will be 96,522,184 authorized
and unissued shares of Common Stock and 10,000,000 authorized and unissued
shares of Preferred Stock, par value $.01 per share (the "Preferred Stock"). The
existence of authorized but unissued Common Stock and Preferred Stock may enable
the Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a merger, tender offer, proxy
solicitation or otherwise. In this regard, the Company's Amended and Restated
Articles of Incorporation (the "Restated Articles of Incorporation") grant the
Board of Directors of the Company broad power to establish the rights,
preferences and privileges of authorized and unissued Preferred Stock without
shareholder approval. The issuance of shares of Preferred Stock pursuant to the
Board of Director's authority described above could decrease the amount of
earnings and assets available for distribution to holders of Common Stock or
adversely affect the rights and powers, including voting rights, of such
holders. The issuance of Common Stock or Preferred Stock could also have the
effect of delaying, deferring or preventing a change in control of the Company,
including transactions in which the shareholders might otherwise receive a
premium for their shares over the then current market price, and may adversely
affect the market price of the Common Stock. The Board of Directors does not
currently intend to seek shareholder approval prior to any issuance of Common
Stock or Preferred Stock, unless otherwise required by law. The Company is also
subject to prior regulatory approval by the FCC and various state regulatory
agencies for a transfer of control of the Company or for the assignment of the
Company's intrastate certification authority and its international authority.
The 1934 Communications Act provides that non-U.S. citizens, foreign governments
or their representatives or corporations organized under the laws of a foreign
country may not own in the aggregate more than 20% of a company that owns common
carrier radio licenses such as the Company. In addition, because the Company
holds FCC authority to provide international service, the FCC will scrutinize an
ownership interest in the Company of greater than 25%, or a controlling interest
at any level, by a dominant foreign carrier. International carriers, such as the
Company, must notify the FCC 60 days in advance of an acquisition of a 10% or
greater interest by a foreign carrier in such carriers. Furthermore, the
Company's bank loan agreement provides that an event of default thereunder will
occur if all or a controlling interest in the Company's capital stock is sold,
assigned or otherwise transferred. Any of the foregoing factors could have the
effect of delaying, deferring or preventing a change of control of the Company.
See "Business--Government Regulation" and "Description of Capital
Stock--Preferred Stock" and "--Certain Anti-Takeover Matters."
 
ABSENCE OF PRIOR PUBLIC MARKET; VOLATILITY OF STOCK PRICE
 
    Prior to the Offering, there has been no public market for shares of Common
Stock and there can be no assurance that an active market will develop or be
sustained following the Offering. The initial public offering price for the
shares of Common Stock sold in the Offering will be determined through
negotiations between the Company and the Representative and will not necessarily
reflect the market price for the Common Stock following the Offering. The market
price for the Common Stock following the Offering will be influenced by a number
of factors, including the depth and liquidity of the market for the Common
Stock, investor perceptions of the Company's and competitors' operating results
and general economic and other conditions. The stock market has experienced
volatility, particularly with respect to the market prices of equity securities
of many technology and telecommunications companies. The volatility often has
been unrelated to the operating performance of the affected companies. These
market fluctuations may adversely affect the price of the Common Stock. See
"Underwriting."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    No prediction can be made as to the effect, if any, that future sales of
shares, or the availability of such shares for future sales, will have on the
market price of the Common Stock of the Company. Sales of a substantial number
of shares of Common Stock in the public market following the Offering, or the
 
                                       15
<PAGE>
perception that such sales may occur, could adversely affect the market price
for the Common Stock. Upon completion of the Offering, the Company will have
outstanding 3,477,816 shares of Common Stock (3,665,316 shares if the
Underwriters' over-allotment option is exercised in full), assuming no exercise
of options or warrants after the date of this Prospectus. Of these shares, the
1,250,000 shares offered hereby (1,437,500 shares if the Underwriters'
over-allotment option is exercised in full) will be freely tradeable without
restriction or further registration under the Securities Act, unless purchased
by "affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act ("Rule 144"). The remaining 2,227,816 shares of Common Stock
outstanding upon completion of the Offering are "restricted securities," as that
term is defined in Rule 144. Upon expiration of certain Lock-Up Agreements (as
defined below) one year after the effective date of the Offering, approximately
2,225,008 shares will be eligible for sale subject to the timing, volume and
manner of sale restrictions of Rule 144. The 2,808 remaining shares held by an
existing shareholder will become eligible for sale over a period of less than
one year. In addition, 13,919 shares subject to outstanding vested stock
options, if exercised, will become eligible for sale 90 days after the effective
date of the Offering and, upon expiration of certain Lock-Up Agreements, an
additional 146,695 shares subject to outstanding stock options under the
Company's Employee Incentive Stock Option Plan (the "Incentive Stock Option
Plan") (including unvested stock options the vesting of which will be
automatically accelerated upon completion of the Offering), if exercised, will
be eligible for sale, in each case subject to the restrictions of Rule 701 under
the Securities Act, unless sold pursuant to an effective registration statement
under the Securities Act. See "--Significant Capital Requirements" and "Shares
Eligible for Future Sale."
 
DILUTION TO NEW INVESTORS
 
    Investors purchasing shares of Common Stock in the Offering will experience
immediate and substantial dilution in net tangible book value of approximately
$4.39 per share of Common Stock (assuming an initial public offering price of
$8.00 per share). To the extent outstanding options to purchase the Company's
Common Stock are exercised, there will be further dilution. See "Dilution."
 
LACK OF DIVIDENDS
 
    The Company has never paid dividends on its Common Stock and does not
anticipate paying any cash dividends on its Common Stock in the foreseeable
future and, in certain circumstances, is prohibited from doing so under the
terms of its bank credit facility. See "Dividend Policy" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operation--Liquidity and Capital Resources."

<PAGE>
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 1,250,000 shares of
Common Stock offered by the Company hereby are estimated to be $8.6 million
($10.0 million if the over-allotment option granted to the Underwriters by the
Company is exercised in full), assuming an initial public offering price of
$8.00 per share (the midpoint of the range of the proposed initial public
offering price) and after deducting estimated offering expenses and underwriting
discounts and commissions payable by the Company. The Company intends to use the
estimated net proceeds as follows: (i) approximately $7.7 million will be
applied to acquire equipment for the continued development of communications
infrastructure for the Company's network, including microwave and fiber optic
equipment to expand the Company's carrier services; (ii) approximately $680,000
will be used to repay a capitalized lease; and (iii) approximately $220,000 will
be used for working capital and general corporate purposes. Pending application
of the proceeds as described above, the Company intends to invest the net
proceeds of the Offering in short-term, investment-grade, interest-bearing
securities.
 
    The Company intends to use approximately $680,000 of the estimated net
proceeds of the Offering to fully pay the outstanding balance of all rental
payments due and to become due under a lease pursuant to which the Company
acquired a tandem switch, and related equipment and maintenance services, for
the Company's telecommunications network. The term of the lease commenced in
January 1997 and expires five years thereafter. The lease included a related
agreement for switch maintenance services, which commenced in January 1997 and
expires two years thereafter. The Company currently is required to make monthly
payments under the lease of approximately $11,500 for the switch and related
equipment and approximately $2,300 for maintenance services. Upon payment in
full of all outstanding amounts under such lease, the Company will acquire title
to the tandem switch and related equipment.
 
                                DIVIDEND POLICY
 
    The Company has never paid dividends on its Common Stock and does not
anticipate paying dividends on the Common Stock in the foreseeable future. In
addition, under the terms of the Company's bank line of credit, the Company may
not pay dividends without the prior consent of the lending bank. The Company
expects that it will retain all available earnings generated by the Company's
operations for the development and growth of its business. Any future
determination as to the payment of dividends will be made in the discretion of
the Board of Directors of the Company and will depend upon the Company's
operating results, financial condition, capital requirements, general business
conditions and such other factors as the Board of Directors deems relevant.

<PAGE>
                                    DILUTION
 
    The net tangible book value of the Company as of December 31, 1996 was
$3,968,755, or $1.78 per share of Common Stock. Net tangible book value per
share represents the amount of the Company's total tangible assets reduced by
the amount of its total liabilities, divided by the total number of outstanding
shares of Common Stock. After giving effect to the sale of the shares of Common
Stock offered hereby and the receipt and application of the estimated proceeds
therefrom at an assumed initial public offering price of $8.00 and after
deducting estimated underwriting discounts and commissions and estimated
expenses of the Offering, the adjusted net tangible book value of the Company at
December 31, 1996 would have been $12,568,755 or $3.61 per share. This
represents an immediate increase in the net tangible book value of $1.83 per
share to existing shareholders and an immediate dilution in net tangible book
value of $4.39 per share to new investors purchasing Common Stock in the
Offering. The following table illustrates the per share dilution to new
investors:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
SELECTED CONSOLIDATED FINANCIAL DATA, CONSOLIDATED FINANCIAL STATEMENTS AND
NOTES THERETO AND THE OTHER FINANCIAL INFORMATION CONTAINED ELSEWHERE IN THIS
PROSPECTUS. MOREOVER, THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT
INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS MAY DIFFER
SIGNIFICANTLY FROM THE RESULTS DISCUSSED IN THE FORWARD-LOOKING STATEMENTS.
FACTORS THAT MIGHT CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT
LIMITED TO, THOSE DISCUSSED IN "RISK FACTORS."
 
OVERVIEW
 
    The Company's total sales are derived from the provision of a variety of
services, including telecom and carrier services, land mobile services and
product resales. Telecom and carrier services include the resale of long
distance, the provision of private lease lines, the resale of equipment and the
provision of related services to furnish and install telecommunications systems.
The Company recently has installed a tandem switch at its facility in Houston,
Texas and when such switch is fully operational (which the Company expects to
occur by the end of the fourth quarter of fiscal 1997), the Company will provide
services as a switch-based long distance carrier. Land mobile services consist
of the rental, sale, service and maintenance of two-way radio communications
systems.
 
    In connection with product resales, the Company serves as the exclusive
manufacturer's representative of Alcatel products to the U.S. oil and gas
industry. In fiscal 1996, the Company provided services to Shell, which included
the resale of a significant amount of Alcatel products. For the year ended June
30, 1996 and for the six months ended December 31, 1996, Shell purchased from
the Company approximately $10.6 million and $4.7 million of Alcatel products and
other equipment and hardware, representing approximately 38.0% and 30.0%,
respectively, of total sales during such periods. Although profitable, the sale
of Alcatel products to Shell significantly reduced the Company's gross margin in
these periods. The Shell project is expected to be substantially completed in
fiscal 1997 and, therefore, is not expected to contribute in a material manner
to the Company's total sales in future periods.
 
    The Company was founded in 1981 as a contract supplier of communications
technology installation and equipment leasing services, and over the ensuing
years broadened the scope of its service offerings to include microwave, two-way
radio and related wireless services and technologies for an expanded customer
base, primarily comprised of major oil and gas companies operating in the Gulf
of Mexico region. During this period, the Company began to provide an increasing
variety of services to its oil and gas customers in other remote and
underdeveloped regions around the world.
 
    To support its international expansion, in 1994 the Company began providing
telecommunications services and network support inside the former Soviet Union
to United States oil and gas customers. As the Company expanded its service
offerings and developed greater infrastructure, it commenced service as a long
distance carrier and as a switchless reseller in 1995. The Company is continuing
to expand its network through a recently-acquired tandem switch and the
installation of fiber optic cable and microwave radios in targeted service
areas. In connection with such expansion, the Company has also received CLEC
status in Texas and has applied for CLEC status in Louisiana. See "Risk
Factors--Risks Associated with Entry into Local Phone Service Market and Other
New Markets."
 
    While annual growth rates of the Company's total sales since 1992 have
ranged from 6.3% to 76.0%, the Company's quarterly operating results have varied
significantly in the past, and can be expected to vary in the future. These
fluctuations in operating results generally are caused by a number of factors,
including changes in the Company's services and product mix, levels of product
resales, adverse weather conditions in customer locations, the degree to which
the Company encounters competition in its existing or target markets, general
economic conditions, the volume and timing of orders received during the period,
sales

and marketing expenses related to entering new markets, the timing of new
product or service introductions by the Company or its competitors and changes
in billing rates by the Company or its competitors.

COMPARISON OF SIX MONTHS ENDED DECEMBER 31, 1996 AND 1995
 
    TOTAL SALES.  Total sales increased $8.4 million or 116.7% to $15.6 million
for the six months ended December 31, 1996 from $7.2 million for the comparable
period in the prior fiscal year. Of this increase, $3.7 million, or 44.0%,
resulted from increases in the Company's telecom, carrier and land mobile
services, while $4.7 million, or 56.0%, resulted in part from product resales to
a single customer. The product resales are expected to be substantially
completed in fiscal 1997 and, therefore, are not expected to contribute in a
material manner to the Company's total sales in future periods.
 
    GROSS MARGIN.  Gross profit increased $989,000 or 33.3% to $4.0 million for
the six months ended December 31, 1996 from $3.0 million for the comparable
period in the prior fiscal year, representing gross margins of 25.3% and 41.3%,
respectively. The decrease in margin was due in principal part to the lower
margin on product resales in 1996 and increases in materials and supplies
expense. Excluding product resales, gross profit for the six months ended
December 31, 1996 would have been approximately $3.6 million, representing a
gross margin of 34.6%.
 
    SELLING EXPENSES.  Selling expenses increased $101,000 or 25.6% to $495,000
for the six months ended December 31, 1996 from $394,000 for the comparable
period in the prior fiscal year. Selling expenses as a percentage of total sales
decreased to 3.2% from 5.5% during these respective periods. The increase in
selling expenses resulted from the addition of sales personnel and from
increases in travel and advertising.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased $310,000 or 16.0% to $2.2 million for the six months ended December
31, 1996 from $1.9 million for the comparable period in the prior fiscal year.
As a percentage of total sales, general and administrative expenses
 
                                       22
<PAGE>
decreased to 14.3% for the six months ended December 31, 1996 from 26.8% for the
comparable period in the prior fiscal year. The decrease in general and
administrative expenses as a percentage of sales was primarily due to product
resales that required little or no incremental administrative expense. The
increases in the dollar amount of general and administrative expenses over these
periods were due in principal part to increased telephone expense, insurance
expense, rent expense and legal expense relating to facilities and personnel
additions in Houston, Texas and Lafayette, Louisiana. Exclusive of product
resales, general and administrative expenses for the six months ended December
31, 1996 would have been approximately 21.4% of total sales.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
$152,000 or 31.5% to $635,000 for the six months ended December 31, 1996 from
$483,000 in the comparable period in the prior fiscal year. This increase was
primarily attributable to the acquisition of an additional $2.3 million of
property, plant and equipment, comprised of $1.8 million in equipment for
satellite, microwave and other equipment and $500,000 for computers, furniture
and fixtures, service vehicles and test equipment.
 
    NET INTEREST EXPENSE.  Net interest expense increased $64,000 or 43.0% to
$213,000 for the six months ended December 31, 1996 from $149,000 for the
comparable period in the prior fiscal year. The Company's borrowings increased
to $6.0 million for the six months ended December 31, 1996 from $2.8 million for
the comparable period in the prior fiscal year. Borrowings were reduced in 1995
by the receipt of $2.0 million from Shell as a deposit under a product resale
contract. The increase in borrowings was used to fund acquisitions of property,
plant and equipment.
 
    OTHER INCOME, NET.  Other income decreased $96,000 or 84.2% to $18,000 for
the six months ended December 31, 1996 from $114,000 for the comparable period
in the prior fiscal year. The decrease resulted from a decrease in earnings from
the Company's 50%-owned subsidiary, Kenwood Systems Group, Inc. ("Kenwood").
 
    INCOME TAX EXPENSE.  Provision for income taxes increased $90,000 or 204.5%
to $134,000 for the six months ended December 31, 1996 from $44,000 for the
comparable period in the prior fiscal year, which represents an effective tax
rate of 34.0% for each period.
 
COMPARISON OF FISCAL YEARS ENDED JUNE 30, 1996 AND 1995
 
    TOTAL SALES.  Total sales increased by $12.0 million or 75.9% to $27.8
million for fiscal 1996 from $15.8 million for fiscal 1995. This increase
resulted in principal part from product resales of approximately $10.6 million,
with the remainder of the increase attributable to growth in the Company's
telecom, carrier and land mobile services. Excluding product resales, total
sales for fiscal 1996 would have been $17.3 million. Since such product resales
are expected to be substantially completed in fiscal 1997, they are not expected
to contribute in a material manner to the Company's total sales in future
periods.
 
    GROSS MARGIN.  Gross profit increased $1.2 million or 19.7% to $7.3 million
in fiscal 1996 from $6.1 million in fiscal 1995, representing gross margins of
26.5% and 39.0%, respectively. The decrease in gross margin primarily was due to
the lower profit margin from product resales. Excluding product resales, gross
profit would have been approximately $6.6 million in fiscal 1996, representing a
gross margin of 38.0%.
 
    SELLING EXPENSES.  Selling expenses decreased $20,000 or 2.4% to $842,000,
or 3.0% of revenues, in fiscal 1996 from $862,000, or 5.5% of revenues, in
fiscal 1995. Advertising and promotion expenditures increased $81,000, travel
increased $21,000 and salaries and employee benefits decreased $110,000, which
reflected the reassignment of certain employees to other departments.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased $720,000 or 20.4% to $4.2 million in fiscal 1996 from $3.5 million in
fiscal 1995. As a percentage of total sales, general and administrative expenses
decreased to 15.3% for fiscal 1996 from 22.4% for fiscal 1995. The increase in
 
                                       23
<PAGE>
general and administrative expenses was primarily due to a higher level of
expenses in fiscal 1996 associated with the Company's international operations
and related travel, including increased activity in Russia and South America as
well as a project in Bosnia that was started and completed in fiscal 1996. In
addition, general and administrative expenses were higher in fiscal 1996 due to
increases in insurance costs and employee compensation resulting from the
development of the Company's infrastructure to accommodate growth specifically
through an increased number of employees, increased telephone expenses relating
to increased activity in the Company's international operations and costs
associated with opening offices in Lafayette and New Orleans, Louisiana.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
$183,000 or 22.3% to $1.0 million in fiscal 1996 from $820,000 in fiscal 1995.
This increase was principally attributable to an additional $1.2 million of
property, plant and equipment, comprised of $621,000 for satellite, microwave
and other telecommunications equipment, and $579,000 for computers, furniture
and fixtures, service vehicles and test equipment.
 
    NET INTEREST EXPENSE.  Net interest expense increased $26,000 or 10.6% to
$270,000 in fiscal 1996 from $244,000 in fiscal 1995. The increase in interest
expense was due to an increase of $350,000 in borrowings under the Company's
credit lines. Interest expense was minimized during fiscal 1996 as a result of a
$2.0 million deposit received from Shell under a product resale contract.
 
    OTHER INCOME, NET.  Other income in fiscal 1996 and fiscal 1995 resulted
from the Company's 50% ownership interest in Kenwood, as well as certain asset
dispositions effected in such periods. Such items were not material to the
Company's operating results in fiscal 1996 or fiscal 1995.
 
    INCOME TAX EXPENSE.  Provision for income taxes increased $23,000 or 7.8% to
$316,000 in fiscal 1996, representing an effective income tax rate of 30.0%,
from $293,000 in fiscal 1995, representing an effective tax rate of 35.4%. The
decrease in the effective tax rate in fiscal 1996 primarily was due to the
availability of foreign tax credits in such year.
 
COMPARISON OF FISCAL YEARS ENDED JUNE 30, 1995 AND 1994
 
    TOTAL SALES.  Total sales increased $935,000 or 6.3% to $15.8 million for
fiscal 1995 from $14.9 million for fiscal 1994. This increase resulted from a
general increase in sales of the Company's telecom, carrier and land mobile
services, including the establishment of the Company's long distance carrier
services.
 
    GROSS MARGIN.  Gross profit increased $1.3 million or 28.5% to $6.1 million
in fiscal 1995 from $4.8 million in fiscal 1994, representing gross margins of
39.0% and 32.2%, respectively. The increase in gross margin in fiscal 1995
resulted, in principal part, from reductions in the cost of direct labor and
materials.
 
    SELLING EXPENSES.  Selling expenses decreased $30,000 or 3.4% to $862,000 in
fiscal 1995 from $892,000 in fiscal 1994. The decrease in selling expenses was
attributable to the focusing of marketing resources on activities that yielded
higher returns.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased $358,000 or 11.3% to $3.5 million in fiscal 1995 from $3.2 million in
fiscal 1994. As a percentage of total sales, general and administrative expenses
increased to 22.4% for fiscal 1995 from 21.4% for fiscal 1994. The increase for
1995 was minimized by reduced expenditures made in areas such as contract
services, bad debts, which included a write off of $84,500 in fiscal 1994, data
processing expenses and telephone expenses. Items increasing in fiscal 1995
included expenditures on foreign ventures due to increased activity in Russia,
accounting and legal expenses and training and consulting resulting from the
installation of new accounting software.
 
                                       24
<PAGE>
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
$249,000 or 43.6% to $820,000 in fiscal 1995 from $571,000 in fiscal 1994. The
increase was principally attributable to an additional $1.5 million of property,
plant and equipment comprised of $1.1 million for satellite, microwave and other
equipment and $420,000 for computers, furniture and fixtures, service vehicles
and test equipment.
 
    NET INTEREST EXPENSE.  Interest expense increased $244,000 or 13.5% in
fiscal 1995 from $215,000 in fiscal 1994. Outstanding debt increased $3.6
million or 31.0% in fiscal 1995 from $2.7 million in fiscal 1994. This increased
financing was used primarily to fund the Company's growth in property, plant and
equipment.
 
    OTHER INCOME, NET.  Other income decreased to $138,000 in fiscal 1995 from
$253,000 in fiscal 1994. Other income is composed of earnings from Kenwood, and
the gain incurred on the disposition of certain assets.
 
    INCOME TAX EXPENSE.  The Company's fiscal 1995 provision for income taxes
was $293,000, representing an effective rate of 35.0%. In fiscal 1994, the tax
provision amounted to $41,000, representing an effective tax rate of 22.3%.
 
QUARTERLY RESULTS
 
    The following table presents selected quarterly financial information for
the periods indicated. This information has been derived from unaudited
Consolidated Financial Statements which, in the opinion of management, include
all adjustments (consisting only of normal recurring adjustments) necessary for
a fair presentation of such information. These operating results are not
necessarily indicative of results for any future period.
 
    The Company's quarterly operating results have varied significantly in the
past and can be expected to vary in the future. These fluctuations in operating
results generally are caused by a number of factors, including changes in the
Company's services and product mix, levels of product resales, adverse weather
conditions in customer locations, the degree to which the Company encounters
competition in its existing or target markets, general economic conditions, the
volume and timing of orders received during the period, sales and marketing
expenses related to entering new markets, the timing of new product or service
introductions by the Company or its competitors and changes in billing rates by
the Company or its competitors.

LIQUIDITY AND CAPITAL RESOURCES
 
    During the six months ended December 31, 1996, the Company generated
$334,000 of cash from operating activities, borrowed an additional net amount of
$2.0 million from credit facilities, received payment of $142,000 from
collections on outstanding notes receivable and received $10,000 from the sale
and issuance of Common Stock to an employee. The Company spent $2.4 million on
property and equipment (net of proceeds of $29,000 from certain dispositions of
assets) and increased its investment in an unconsolidated subsidiary by $50,000.
These activities provided an increase in the Company's cash balance of $62,000
to a balance of $423,000 at December 31, 1996.
 
    The Company's working capital increased to $2.1 million at December 31, 1996
from $1.8 million at June 30, 1996. Accounts receivable decreased from $5.5
million at June 30, 1996 to $5.0 million at December 31, 1996, while inventory
increased from $987,000 at June 30, 1996 to $1.8 million at December 31, 1996.
In addition, the current portion of notes payable increased from $1.0 million at
June 30, 1996 to $1.1 million at December 31, 1996, while deferred revenue and
customer deposits increased from $614,000 at June 30, 1996 to $838,000 at
December 31, 1996.
 
    During fiscal 1996, the Company generated $737,000 of cash from operating
activities, borrowed an additional net amount of $350,000 from credit
facilities, received payment of $264,000 from collections on outstanding notes
receivable (net of new notes issued for $396,000), and received $10,000 from the
sale and issuance of Common Stock to an employee. The Company also spent $1.3
million on property, plant and equipment (net of proceeds of $202,000 from
certain dispositions of assets). These activities provided an increase in the
Company's cash balance of $70,000 at June 30, 1995 to a balance of $361,000 at
June 30, 1996.
 
    The Company's working capital increased to $1.8 million at June 30, 1996,
representing an increase of $2.1 million from the negative working capital
position of $265,000 at June 30, 1995. The Company restructured its credit
facility to reclassify some borrowings as long term in fiscal 1996 that were
considered current obligations in fiscal 1995. The increased working capital was
used to support growth in the Company's core business as well as an increase in
accounts receivable from $2.0 million in fiscal 1995 to $5.5 million in fiscal
1996 and an increase in inventory from $601,000 at June 30, 1995 to $987,000 at
June 30, 1996. Offsetting these increases was a higher balance of accounts
payable and accrued liabilities to $3.9 million in fiscal 1996 from $1.1 million
in fiscal 1995. The current portion of notes payable for this period decreased
to $1.0 million in fiscal 1996 from $2.3 million in fiscal 1995.
 
    The Company has a bank line of credit of $4.5 million of which $2.3 million
was advanced at December 31, 1996. Line of credit availability is based upon
eligible accounts receivable and inventory with interest on borrowed funds at
prime plus 0.75% and a fee equal to 0.50% is charged on any unused portion of
the facility. See Note 5 to Notes to Consolidated Financial Statements. The bank
line is collateralized by substantially all of the Company's assets and expires
in December 1998, although it may be terminated by the Company through December
20, 1997 for a prepayment premium of 1% of the maximum amount of credit.
Thereafter through December 1998, it may be terminated for a fee of 0.50% of the
maximum amount of credit. The Company has other credit facilities with its bank
lender for specific items of equipment which are collateralized by those items.
The credit agreement prohibits the payment of dividends without prior approval
of the lender and requires the Company to maintain certain covenants
and financial ratios including working capital and net worth ratios. The Company
has recently received an increase of $2.0 million and is currently negotiating
for additional facilities to finance equipment for the provision of services to
customers. In December 1996, the Company violated a financial covenant under the
credit agreement. The bank lender did not declare the Company in default and
waived the violation. In addition, the bank lender has amended the financial
covenant at issue, such that the Company does not expect to be in violation of
such covenant in the future.
 
    The Company currently expects that capital expenditures for the continued
development of infrastructure and associated growth will be approximately $9.0
million in fiscal 1997, $6.7 million of which will occur
 
                                       26
<PAGE>
in the second half of fiscal 1997. The Company entered into an agreement in
December 1996 to acquire microwave radios from a customer. The Company will be
required to make a cash payment of approximately 30% of the purchase price on
April 1, 1997. The balance will be carried in a note payable to the customer
bearing interest at 6.75% with monthly principal and interest payments to begin
in July 1997, with a final payment of principal and interest to be made in June
2006. The Company anticipates that, based on current plans and assumptions
relating to its operations, upon completion of the Offering its financial
resources and equipment financing arrangements will be sufficient to fund the
Company's growth and operations for approximately twelve months from the date of
this Prospectus. The Company believes that its capital needs at the end of such
period will continue to be significant and, therefore, the Company will continue
to seek additional sources of capital. Further, in the event the Company's plans
or assumptions change or prove to be inaccurate, or if the Company consummates
any unplanned acquisitions of businesses or assets, the Company may be required
to seek additional sources of capital sooner than currently anticipated. Sources
of additional capital may include public and private equity and debt financings,
sales of nonstrategic assets and other financing arrangements. See "Risk
Factors--Significant Capital Requirements" and "Use of Proceeds."
 
NEW ACCOUNTING STANDARDS
 
    In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock-Based Compensation." As a result of this statement,
the Company will begin to provide additional disclosures related to its stock
based compensation plans in its fiscal 1997 financial statements. Adoption of
SFAS No. 123 will not have a material effect on the Company's financial position
or results of operations. The Company adopted the provisions of SFAS No. 121,
"Accounting for the Impairment of Long-lived Assets," in its 1996 fiscal year,
which did not have a material effect on the Company's financial position or
results of operations.

BUSINESS OVERVIEW
 
    The Company provides advanced communications solutions to customers with
operations in remote, difficult-access regions and in areas around the world
where government deregulation has created new market opportunities. The Company
delivers comprehensive communications services to its customers by utilizing a
broad range of analog and digital technologies, including satellite, microwave
radio, conventional two-way radio and fiber optic cable. The Company's core
business to date has focused on the provision of communications solutions for
customers in the oil and gas industry, such as AMOCO, British Gas, Chevron,
Conoco, Exxon and Shell. Such customers exemplify users with unique
communications needs related to the remote, difficult-access nature of their
operating locations. By providing a wide range of communications solutions to
its oil and gas customers, the Company has developed a high level of expertise
and a unique skill set in planning, designing and implementing total
communications solutions for multi-site customers with operations located in
remote regions or underdeveloped areas where the existing communications
infrastructure is insufficient to meet advanced telecommunications needs. The
Company intends to leverage this skill set and expertise by supplying
communications services to multi-site customers outside of the oil and gas
industry, particularly customers with operations located near the Company's
existing and planned telecommunications infrastructure. Potential additional
customers include health care providers, financial institutions and other
multi-location communication-intensive companies, such as large publishing
companies.
 
    The Company recently has installed a tandem switch and a value-added
services platform in Houston, Texas. This switch and platform enable the Company
to connect its digital network with the networks of other carriers, thereby
permitting the routing of phone calls in a cost-competitive manner. As the
Company's communications network in the Gulf Coast expands, the Company intends
to install additional switches in other strategic locations. The Company
recently has received approval to serve as a CLEC in select locations in Texas
and has applied for CLEC status in Louisiana. As a result, the Company believes
that it is well positioned to use the full capacity of its existing and planned
infrastructure by providing call routing to other carriers and, in select
locations, by providing call completion services at profit margins that the
Company believes will be higher than those achievable without CLEC status. As a
CLEC offering competitive rates for call completion services, the Company
expects that cellular, PCS and other long distance carriers will become
additional customers.
 
    The Company provides its telecommunications services through a satellite
network, a microwave network, wireless licenses and carrier agreements for long
distance service combined with a switch-based network. The IWL satellite network
includes two 5.6 meter Ku band earth stations and access agreements for Orion
and GTE Spacenet satellites. The Company's microwave network includes a system
that has been built by the Company onshore in the Texas Gulf Coast region and
extends offshore into the Gulf of Mexico. Through various agreements, the
Company has access to capacity from other microwave systems owned by carriers
throughout the Texas and Louisiana Gulf Coast region. In order to provide its
wireless mobile services, the Company owns various radio systems that provide
two-way voice communications and has obtained 35 FCC licenses with approximately
320 frequency pairs. The Company's long distance services are provided through
the recently-installed tandem switch as well as through agreements with other
long distance carriers. The LEC services that the Company intends to provide
will be obtained from existing LECs on a reseller basis and from the Company's
generation of such services through the acquisition of its own end-office switch
and access to fiber optic cable obtained by the Company or on which the Company
leases capacity. The Company's relationship with international oil and gas
company customers created an opportunity to expand its operations globally by
providing communications solutions for these customers' other facilities located
in remote or underdeveloped locations around the world. The Company currently
has domestic offices in Houston and Friendswood, Texas and Lafayette and New
Orleans, Louisiana and an international office in Moscow, Russia.

MARKET OPPORTUNITY
 
    The introduction and proliferation of new communications technologies,
together with global socioeconomic development, are contributing to significant
increases in demand for telecommunications services throughout the world.
Advances in communications delivery technology, including those achieved through
the deployment of satellite systems and the development of data compression
technologies, have expanded the variety of information that can be digitized as
well as the geographic scope of where such data may be transmitted or received.
Businesses in numerous industries around the world increasingly depend upon
their ability to effectively and quickly transmit larger quantities and more
varied types of data, including voice and video. As each technological advance
creates a new service or product, or enhances the quality or reduces the cost of
existing services and products, the demand for telecommunications services
increases. In addition, political and economic changes in many regions of the
world have contributed to the emergence of additional global market
opportunities in a variety of industries and an increased rate of adoption of
Western business practices in previously non-Westernized areas. Examples of such
changes include the spread of multi-party governments and free market economies
in Eastern Europe, the unification effort in Western Europe, the North American
Free Trade Agreement and the privatization of government-operated industries in
South America. The Company believes that these changes have escalated the demand
for Western telecommunications services, particularly in remote regions of the
world or in regions where the telecommunications infrastructure is
underdeveloped.
 
    The telecom services industry is being transformed further by the
deregulation of telecommunications markets around the world. In the United
States, a court decree in 1984 required AT&T to divest its local systems into
seven independent Regional Bell Operating Companies, which own the BOCs that
provide local services. This action resulted in the separation of the long
distance market from the local exchange services market, with the outcome being
an opening of the long distance market to competition. The enactment of the 1996
Telecommunications Act established an expansive framework for greater
competition, including within the local exchange services market. Under the 1996
Telecommunications Act, state laws prohibiting competition are preempted and
CLECs, such as the Company, have legal rights to interconnect with the
facilities of the incumbent LECs, including the BOCs and GTOCs, resell local
services that were previously provided only by the BOCs and GTOCs, and deliver
CLEC-provided local services as well as long distance services.
Telecommunications revenues of CLECs grew almost 80% in 1996 to $2.1 billion,
compared with nearly $1.2 billion in 1995, according to the 8th Edition of the
ANNUAL REPORT ON THE COMPETITIVE TELECOMMUNICATIONS INDUSTRY. Whereas the CLEC
industry in 1995 derived 42% of its service revenues from private line and
dedicated access services and only 20% from local and switched access services,
in 1996 switched services constituted 36% of total CLEC telecom revenues.
Deregulation of telecommunications markets is occurring at the international
level as well, as demonstrated by the recent 68-nation World Trade Organization
agreement on communications services, which reflects efforts to dismantle
government-owned telecommunications monopolies throughout Europe, Asia and
India. The Company believes that deregulation efforts, both domestically and
internationally, will continue to create opportunities for new entrants in the
telecom services industry, particularly companies capable of meeting the
challenges presented by remote or underdeveloped geographies.
 
    While the demand for telecommunications services is increasing worldwide,
the Company believes that the exploration and development activities
characteristic of the oil and gas industry have placed that industry, in
particular, at the forefront in applying modern communications technologies in
remote regions of the world or regions that lack developed telecommunications
infrastructure. The oil and gas industry is characterized by companies with
global operations that require reliable data and voice communications. Companies
engaged in oil and gas exploration operate sophisticated seismic and drilling
equipment in areas that are often uninhabited or otherwise present logistical
adversity, such as offshore platforms that operate in the Gulf of Mexico or the
North Sea and remote areas of Russia or South America. Information gathered by
an oil and gas company at such locations often must be transmitted to the
company's main office for evaluation, with subsequent communications between the
remote and main office locations being necessary to manage the conduct of such
operations. Furthermore, the Company believes that oil and gas companies are
increasingly outsourcing their telecommunications services needs. Because each
active
 
                                       29
<PAGE>
drilling rig or seismic unit typically requires communications services, the
Company believes that growth in the demand for telecom services within the oil
and gas industry generally relates to the overall level of activity in the
petroleum industry. According to the OIL INDUSTRY OUTLOOK published by PennWell
Publishing Company in August 1996, worldwide petroleum industry capital
expenditures were approximately $73.9 billion in 1995, up from $65.6 billion in
1990, and are expected to grow to approximately $94.6 billion in the year 2000,
for an increase of approximately 28%. The OIL INDUSTRY OUTLOOK also reports
that, at the end of 1995, there were approximately 723 active drilling rigs in
the U.S., and this number is expected to grow to approximately 920 active
drilling rigs by the year 2000, for an increase of approximately 27%.
 
    The Company also believes that numerous other industries are taking
advantage of technological advances and socioeconomic development by pursuing
opportunities to expand their operations into remote regions or areas with
underdeveloped telecommunications infrastructure. In some cases, such areas
include highly populated communities in developed and lesser developed
countries. Following the installation of additional infrastructure in such
regions, these communities may be able to make use of the available extra
carrier capacity, even though such additional infrastructure might have been
installed originally as a specific communications solution for a particular
company or end-user. One example of a type of end-user, other than an oil and
gas company, that may experience unique communications challenges requiring
additional infrastructure would be a large publisher. Publication companies
often need to transmit large quantities of news information and other data to
numerous remote locations but may not have access to sufficient wire or fiber
connections. Similarly, health care providers, financial institutions and other
multi-location companies, including other telecommunications carriers,
throughout the world require specialized telecom solutions. The Company believes
that a significant opportunity exists to provide advanced communications
services to end-users outside the oil and gas industry by delivering effective
temporary or permanent solutions at competitive rates and, in doing so, the
Company intends to position itself to serve the telecommunications carrier
service needs of neighboring communities and businesses.
 
IWL STRATEGY
 
    The Company's goal is to become a leading provider of total communications
solutions to end-users with operations in remote, difficult-access regions or in
areas around the world where government deregulation has created new market
opportunities and to leverage this position by providing carrier services to
additional customers located in these same regions. To reach this goal, the
Company intends to pursue the following strategies:
 
    DEVELOP ADDITIONAL COMPANY-OWNED INFRASTRUCTURE.  The Company intends to
develop additional Company-owned infrastructure and plans to leverage that
infrastructure to provide expanded and better quality services to existing and
new customers. By maintaining an ownership interest in the communications
infrastructure installed by the Company for specific customers, the Company can
establish a lasting presence in the regions within which those customers
operate. The Company may then sell communications carrier services to additional
customers by utilizing that same infrastructure. For example, the Company
intends to invest in the required infrastructure, including fiber optic cable,
in certain selected areas of the Texas and Louisiana Gulf Coast region.
 
    VERTICALLY INTEGRATE SERVICE OFFERINGS.  The Company believes that it has
the capability to be a single-source provider of total communications solutions,
including long distance services and local carrier services, and a variety of
complementary services such as two-way radio, paging and Internet access. The
Company intends to aggressively market its existing and new services to
customers through its single-source approach. The Company believes that this
single-source strategy will enable it to increase sales to its existing and
future customers.
 
    DIVERSIFY CUSTOMER BASE.  By providing a wide range of communications
solutions to its oil and gas customers, the Company has developed a high level
of expertise and a unique skill set in planning, designing and implementing
total communications solutions for multi-site customers with operations in
remote regions or underdeveloped areas where the existing communications
infrastructure is insufficient to meet advanced telecommunications needs. The
Company intends to leverage this skill set and expertise
 
                                       30
<PAGE>
by supplying communications services to multi-site customers outside of the oil
and gas industry, particularly customers with operations located near the
Company's existing and planned telecommunications infrastructure. Potential
additional customers include health care providers, financial institutions and
other multi-location companies, such as large publishing companies. In
particular, cellular, PCS and other long distance carriers have become
significant potential additional customers because, as a CLEC, the Company will
be able to complete phone calls at cost-effective rates.
 
    CAPITALIZE ON OPPORTUNITIES CREATED BY GOVERNMENT DEREGULATION AND
GLOBALIZATION TRENDS IN VARIOUS INDUSTRIES.  The Company intends to explore new
markets that opened as a result of the recent trend toward worldwide government
deregulation in the telecommunications industry. Recent U.S. legislation has
opened the domestic local exchange market to competition, and the Company
intends to provide a combination of long distance services and basic local phone
services to domestic customers. To capitalize on opportunities presented by the
changing international regulatory environment and the size of the international
market, the Company intends to target customers who have international
telecommunication needs. In addition, the Company intends to take advantage of
opportunities created by the movement towards a free market economy in certain
parts of the world by providing communications services to companies in a
variety of industries as those companies and industries pursue international
expansion.
 
    EXPAND EXISTING STRATEGIC ALLIANCES AND ESTABLISH NEW ALLIANCES.  The
Company intends to expand its existing strategic alliances and intends to enter
into new strategic alliances that will enable the Company to broaden its
customer base or expand its service offerings. The Company intends to focus on
strategic alliances with suppliers, major customers and long distance carriers
and other telecommunications carriers. The Company believes that such strategic
alliances are an important means of achieving economies of scale and full
utilization of its infrastructure.
 
SERVICE OFFERINGS
 
    TELECOM AND CARRIER SERVICES
 
    The Company currently offers its customers a single source for voice, data
and Internet communications services. The Company provides telecommunications
services in remote, difficult-access regions and in areas around the world where
government deregulation has created new market opportunities. The Company,
utilizing a broad range of analog and digital technologies, provides its telecom
and carrier services through a satellite network, a microwave network, wireless
licenses, and carrier agreements for long distance service combined with a
switch-based network. The Company's satellite network includes two 5.6 meter Ku
band earth stations and access agreements for Orion and GTE Spacenet satellites.
The Company's microwave network includes a system that has been built by the
Company onshore in the Texas Gulf Coast region and extends offshore into the
Gulf of Mexico. Through various agreements, the Company has access to capacity
from other microwave systems owned by carriers throughout the Texas and
Louisiana Gulf Coast region. In order to provide its wireless mobile services,
the Company owns various radio systems that provide two-way voice communications
and has obtained 35 FCC licenses with approximately 320 frequency pairs. The
Company's long distance services are provided through the recently-installed
tandem switch as well as through agreements with other long distance carriers.
The LEC services that the Company intends to provide will be obtained from
existing LECs on a reseller basis and from the Company's generation of such
services through its acquisition of one or more end-office switches and access
to fiber optic cable obtained by the Company or on which the Company leases
capacity.
 
    Related services provided by the Company include project engineering,
telecom installation and maintenance, network management and telecom product
sales and equipment rentals. To provide its customers with total, integrated
communications services, IWL performs many functions, including system
specification, engineering, integration, test and installation. IWL's dedicated
project management and engineering staff has experience in network design and
implementation and has the expertise to engineer, design and install systems
that meet its customers' requirements.
 
    The Company's telecom services also provide the connection between the
common carrier's network and the customer's location. Although such connection
can span large distances, it is commonly referred to as last-mile connectivity.
The Company's Offshore Dedicated Digital Services Program ("ODDS"), which
 
                                       31
<PAGE>
delivers connectivity to offshore locations exemplifies the Company's last-mile
connectivity services in the Gulf of Mexico. ODDS is a fully digital,
communications system that is flexible enough to be reconfigured to a new
location after the customer's drilling rig changes locations.
 
    In order to provide last-mile connectivity in remote locations, the Company
utilizes a variety of equipment and services. Satellite services are used where
access to the world public switch network is not available on other transmission
media and other means of connectivity, such as microwave or fiber optic cable,
are cost prohibitive based on the volume of the data being transmitted. The
public switch network is a direct distance dialing telephone network that is
available for public use that consists of an integrated system of transmission
and switching facilities, signaling processors, and associated operations
support systems that is shared by customers. The Company owns and operates two
satellite earth stations in Friendswood, Texas and has space segment agreements
with Orion and GTE Spacenet to use their respective satellites. Earth stations
receive signals from and transmit signals to orbital satellites. These
satellites have footprints covering parts of the U.S. and Europe. See "Risk
Factors--Risks Associated with International Operations."
 
    The Company-owned digital microwave network in the Gulf of Mexico consists
of five microwave repeaters that cover over 40 drilling sites in a 100 mile
radius. The Company has installed microwave infrastructure where moderate
capacity is required for data transmissions and there is no existing
infrastructure or, if there is such infrastructure, it can not be used cost
effectively. In areas not served by the Company's microwave network, the Company
leases the right to install microwave repeaters on other companies' digital
microwave networks. In addition, for onshore remote communications, radio
telephone is used between the microwave backbone (such as microwave radios) and
destinations within the line of sight of such backbone.
 
    In addition to providing its customers with project-specific telecom
communications solutions, in recent years the Company has expanded the provision
of its long distance carrier services including international services, through
its IWL Connect-TM- division, to provide long distance carrier services. The
Company recently installed a tandem switch and a value-added services platform
in Houston, Texas, thus enabling the Company to market its own long distance
carrier services instead of reselling the services of others. The Company's
domestic and international switched access services include a full range of
services with enhanced features, including: 1+ switched domestic service, which
provides for the origination and termination of calls for direct dial service
and is available in all equal access locations in the U.S. and in the Gulf of
Mexico; 1+ switched international service, which provides for the termination of
calls for direct dial service in virtually every country in the world; 1+
dedicated service via a DS1 connection between the customer's on-premise
equipment and the Company's switching platform, which provides high speed
dedicated access; 800/888 switched and dedicated service, which is provided from
the U.S. and Canada and allows phone calls to terminate to switched access
facilities or over DS1 connections; calling card service, which allows phone
calls to originate in the North American Numbering Plan Area and terminate
worldwide, and which is provided via 800/888 access using authorization codes;
and debit card service, which is provided via 800/888 access providing online
services including voice mail, follow-me-number portability and 1+ dialing. The
Company expects to add additional value-added switched access services in the
future, including ISDN (integrated services digital network), ATM (asynchronous
transfer mode) and frame relay services, which the Company believes will allow
it to leverage its infrastructure investment through a larger customer base. The
Company intends to commence providing long distance services through its own
network by the end of 1997. See "Risk Factors--Competition," "--Risks Associated
with Entry into Local Phone Service Market and Other New Markets" and
"--Reliance on Other Telecommunications Carriers."
 
    Because many of the Company's customers require connectivity to locations
along the Texas and Louisiana Gulf Coast region, the Company is currently
installing additional Company-owned infrastructure in that region, which
includes microwave towers, fiber optic cable and leased capacity. The Company
intends to use this installed network to offer long distance and local exchange
services throughout the Texas and Louisiana Gulf Coast region.
 
                                       32
<PAGE>
    The Company intends to begin providing LEC services in the Texas and
Louisiana Gulf Coast region through reselling existing LEC services and through
generating such services through the Company's own infrastructure. The Company
is currently providing similar services in the Gulf of Mexico. LEC services will
include dial tone service and call termination, which will allow customers to
get new or additional phone lines under a basic service plan. In addition, the
Company will be able to provide value-added services such as: DS3 connectivity
for large corporations with heavy traffic, which need a 45 megabyte DS3 line;
DS1 services for WAN connections or interconnections to other carriers at a
1.544 megabyte rate; and DS0, or 64 kilobyte, connections for specific voice and
data uses over FX (foreign exchange) lines, tie lines and PBXs (private branch
exchanges). Before it can provide LEC services, the Company will need to be
licensed as a CLEC in addition to its existing license as a competitive access
provider ("CAP") in both Texas and Louisiana. The Company has obtained a Service
Provider Certificate of Authority ("SPCOA") in Texas, which qualifies it as a
CLEC in Texas, and has applied for CLEC status in Louisiana, which it expects to
receive by the fourth quarter of fiscal 1997. See "Risk Factors--Risks
Associated with Entry into Local Phone Service Market and Other New Markets."
 
    LAND MOBILE SERVICES
 
    The Company provides two-way radio sales and maintenance services to oil and
gas companies, governmental agencies and petrochemical plants located on the
Texas and Louisiana Gulf Coast through its land mobile radio division ("LMR
Division"). IWL offers a broad line of two-way and trunking radios, paging
products and wireless systems for both voice and data applications. The Company
resells these products, which include: portables; mobiles; two-way repeaters
(repeaters repeat the signal so it can be carried over greater distances); base
stations (which are used to communicate to mobiles and portables); RF (radio
frequency) data modules (which are used for transmitting remote data to a
central site); customized radio consoles; single side band, high-frequency
radios (which are used for long distances that are not in the line of sight);
paging networks; and trunking systems (which allow individual communications
over radios). The Company also engineers and designs new systems and modifies
existing systems to meet its customers' specifications. In addition, the Company
provides complete turnkey design and implementation of conventional and trunking
radio networks, integrates new equipment into existing networks, and engineers
and designs new systems or updates existing systems to meet new FCC regulations
as they are adopted.
 
    The Company maintains a fleet of rental radio equipment for short- or
long-term rentals. Customers rent from the Company to support temporary
communication needs for plant maintenance, shutdowns, disaster recovery,
sporting events and conventions. The Company's inventory of radio equipment
includes intrinsically safe ("IS") portables, which are important to oil and gas
companies because they require the use of IS-rated radio products in the
hazardous or explosive atmospheres typically found in petrochemical plants. The
Company employs factory trained licensed technicians on call 24-hours a day,
seven days a week. These personnel are trained in safety procedures for on-site
service in petrochemical plants. The Company's Land Mobile facility located in
Friendswood, Texas has special approval certification from Factory Mutual System
to repair any IS-rated radio products manufactured by Motorola, EF Johnson or
Ericsson-GE.
 
    PRODUCT RESALES
 
    Product resales currently consist of sales of telecom products to Shell.
Shell has a purchasing contract with the Company for Alcatel radios and other
related equipment and hardware. Sales to Shell under the contract were
approximately $10.6 million and $4.7 million for the year ended June 30, 1996
and for the six months ended December 31, 1996. The Shell project is expected to
be substantially completed in fiscal 1997 and, therefore, is not expected to
contribute in a material manner to the Company's total sales in future periods.
It is possible that the Company may have other large projects consisting
primarily of product resales that will be included in product resales in the
future. See "Risk Factors-- Industry Concentration and Dependence on Major
Customers" and "--Variability in Operating Results" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

SALES AND MARKETING
 
    Since its inception, the Company has utilized a direct sales approach in
marketing its services to its customers. The Company currently has a sales force
of approximately 20 sales representatives, with sales offices located in
Houston, Texas, New Orleans, Louisiana and Moscow, Russia. The Company's direct
sales approach enables it to provide a high level of customer service. To
complement the Company's direct sales efforts, the Company often participates in
various domestic and international industry trade shows and conducts advertising
campaigns in trade publications. The Company plans to expand its existing sales
force and develop new market areas as opportunities for projects arise and as
its infrastructure grows.
 
    The Company targets domestic and international customers that require
turnkey system solutions and other telecommunications services. The Company's
sales force sells frequency bandwidth, call completion and system solutions,
allowing the Company to further develop its own telecommunications
infrastructure. Current and prospective customers are assigned to account
managers, who are principally responsible for providing high levels of contact
and customer service. In addition, the Company utilizes business development
managers to focus on specific customer requirements and opportunities. The
business development manager is typically involved in major projects and the
installation of infrastructure domestically or internationally.
 
STRATEGIC RELATIONSHIPS AND ALLIANCES
 
    Recognizing the importance of strategic alliances in the telecom services
industry, IWL has negotiated several agreements with various manufacturers to
resell their products or to combine their facilities and relationships with the
Company's expertise. Certain of these key alliances are described below:
 
    ALCATEL.  The Company has entered into an agreement with Alcatel under which
the Company serves as the exclusive representative for the sale of Alcatel's
fiber and radio system products to companies in the U.S. oil and gas industry.
In return for Alcatel's agreement not to accept orders directly from such
companies, the Company has agreed to actively pursue purchase orders for
Alcatel's products and to propose only Alcatel's products to its prospective
customers in the U.S. oil and gas industry, except where the Alcatel products do
not meet the technical requirements of the prospective customers. Although the
Company is an exclusive sales representative for such products, Alcatel has
other authorized distributors that are not part of the Alcatel agreement, and
those distributors may or may not provide quotations and accept orders from oil
and gas industry companies. Furthermore, in international transactions, other
divisions of Alcatel or its affiliates and other resellers of Alcatel products
outside of the U.S. have been in the past, and in the future may be, competitive
with the Company using Alcatel or non-Alcatel products. The Alcatel agreement
expired in December 1996; however, the parties have continued to abide by the
terms of the Alcatel agreement while negotiating the terms of a new agreement,
which the parties expect will be substantially similar to the old agreement.
 
    ITAR-TASS.  The Company has established a strategic relationship with
ITAR-TASS, the Russian News Agency, in order to provide information and
communications services using INTELSAT satellite capacity and other facilities.
Under its agreement with ITAR-TASS, the Company has agreed to provide marketing
services, develop proposals for customers, engineer, purchase, ship, install and
test equipment, and provide monitoring and maintenance services on systems owned
or leased by customers. In return, ITAR-TASS has agreed to provide marketing and
sales support and to implement, monitor and maintain a communications backbone
network in the Russian Federation (including purchasing or leasing from the
Company equipment associated with earth stations, cable systems and the
network). Through their collaborative efforts, the Company and ITAR-TASS provide
services to major Western oil companies with operations in Russia such as Exxon,
Conoco/Polar Lights and Amoco.
 
    The ITAR-TASS agreement further provides that the Company will have a right
of first refusal on 6.0 MHz of bandwidth on the Atlantic Ocean Region, 4.5 MHz
of bandwidth on the Indian Ocean Region and 3.0 MHz of bandwidth on the
Asia-Pacific Region INTELSAT satellites. These bandwidths enable the
 
                                       35
<PAGE>
Company to provide international access to space segments as required. ITAR-TASS
has a right of first refusal on all contracts for communications services to the
Russian Federation that are proposed by the Company. Each party has agreed that
they will not compete for projects proposed by the other party and will
coordinate with each other to provide communications services to customers.
However, the agreement is not exclusive, and either party can work with other
entities if, in the opinion of such party, financial or technical considerations
dictate a different working arrangement. The agreement provides that it will
terminate in May 1999, unless either party terminates it sooner. Either party
may end the agreement by giving 60 days written notice if, in the opinion of
that party, business or political conditions call for an earlier termination. No
early termination will affect any existing agreements that the Company has
entered into, and notwithstanding such termination, ITAR-TASS will be required
to provide marketing support and other services with respect to existing
agreements for the remainder of their respective terms.
 
    ENTERGY.  In July 1996, the Company entered into a Memorandum of
Understanding ("MOU") with Interstate FiberNet operating on its behalf and on
behalf of Entergy Technology Corporation ("ETC") for the purpose of defining a
contractual relationship between the parties for the interconnection,
co-location, and leasing capacity of each of the parties' fiber optic cable
networks in Louisiana. The MOU reflects the parties' mutual intent to provide
each other with transport capacity on a leased basis at prevailing carriers'
rates. The MOU also provides that the parties will mutually agree to a formal
set of policies to be provided to customers and that they will move forward
expeditiously to conclude a final agreement embodying the intent set forth in
the MOU. The MOU provides that such final agreement will be for an initial term
of five years, with two additional five-year option terms. There can be no
assurance that the parties will enter into a definitive agreement. See "Risk
Factors--Reliance on Third Parties."
 
CUSTOMER SERVICE
 
    The Company provides customer support for products and services through its
full-service support teams in Friendswood, Texas, Lafayette and New Orleans,
Louisiana, and Moscow, Russia. Support services include: (i) on-site
maintenance, with over 50 technical specialists on call for immediate dispatch
when customers' communications systems require maintenance; (ii) a Network
Operations Center where IWL professionals remotely monitor customers'
communications systems throughout the Gulf of Mexico and around the world seven
days a week, 24 hours a day; (iii) customer support through its LMR Division,
which includes rental packages of portable microwave and satellite systems,
two-way radios, fax machines and cellular phones for customers whose
communications needs are temporary or do not justify the purchase of such
equipment; (iv) training programs designed to maximize the customers'
communications investment, classroom training at customers' sites, and
multimedia video training tools; and (v) research and development for unique
applications where the Company's engineers can custom design or modify hardware
to improve its performance within a particular system.
 
COMPETITION
 
    The nature of the Company's competition is diverse due to the breadth of the
services offered by the Company and the geographic regions in which such
services are provided. The Company is subject to intense competition with
respect to each of its individual service offerings. Many of the Company's
competitors have significantly greater financial, technical, manufacturing,
personnel and marketing resources than the Company. To date, however, the
Company believes that these large competitors generally have not made it a
priority to provide telecommunications services in remote, difficult-access
regions. Should one or more of such companies focus on such services, it would
likely have a material adverse effect on the financial condition, results of
operations and cash flow of the Company. Currently, the Company believes it
competes directly with Autocomm Communications Engineering Corp., Sola
Communications, Inc. and Datacom for the sale of telecommunications services to
oil and gas companies in the Gulf of Mexico. The Company believes that its
ability to compete in the markets in which it operates depends on such factors
as reputation, technical expertise, quality, customer service, knowledge of the
 
                                       36
<PAGE>
business, ease of use, reliability, marketing and distribution channels and the
array of services and products that it can provide. Although the Company
believes that it competes favorably with respect to these factors, there can be
no assurance that the Company will be able to compete successfully in the
future. As the Company pursues new markets, the Company likely will encounter
new competitors. While the recent World Trade Organization agreement or
communications services may result in regulatory changes that could benefit the
Company as it competes in existing markets, or seeks to enter new markets, there
can be no assurance that the agreement will be implemented in a manner that
would benefit the Company or that the pro-competitive effects of the agreement
will not increase the amount of competition encountered by the Company.
 
    DOMESTIC AND INTERNATIONAL LONG DISTANCE.  The Company provides long
distance carrier services both domestically and internationally, which it has
been marketing as a switchless reseller since 1994 and which the Company intends
to provide as a facilities-based carrier beginning in the fourth quarter of its
1997 fiscal year. The Company resells long distance service provided by other
long distance carriers and is in the process of developing a switch-based
network from New Orleans, Louisiana to Corpus Christi, Texas, which, if
completed, will deliver long distance service between the various cities and
communities on the network. The long distance markets are characterized by
intense competition with a number of companies, including very large companies
such as AT&T, MCI and Sprint, that have greater name recognition and greater
financial, technical, network and marketing resources than the Company. In
addition, as a result of the 1996 Telecommunications Act, the BOCs and GTOCs are
able to enter the long distance market. The Company's strategy is to expand its
long distance service only as part of a complete telecommunications solution or
where, due to the establishment of a network, the Company can offer service at
rates less than those currently being offered in the particular market. There
can be no assurance that the Company will not encounter intense competition in
the provision of such services or that it will be successful in attracting
customers for its new services.
 
    LOCAL EXCHANGE SERVICE.  The Company is expanding its operations to provide
local exchange services typically provided by LECs. The local service market has
only recently been opened to new service providers following enactment of the
1996 Telecommunications Act; however, the competition for this market is likely
to be as intense as competition for the long distance market. The services
offered by the Company will compete with those offered by LECs, such as
BellSouth and Southwestern Bell and their affiliates, which currently dominate
the provision of local services in their respective markets. In entering the
local services market, the Company initially intends to serve as a reseller of
LEC services as permitted under the 1996 Telecommunications Act, which allows it
to purchase such services at a discount and then resell them to the public.
However, in entering this market, the Company believes that LECs have long-
standing relationships with their customers, have the ability to subsidize
competitive services with revenues from a variety of other services and benefit
from existing state and federal regulations that currently favor LECs over new
service providers such as the Company in certain respects. While legislative and
regulatory changes have provided increased business opportunities for
competitive telecommunications providers such as the Company, these same changes
have given LECs increased flexibility in the pricing of their services, which
may allow LECs to offer special discounts to the Company's customers and
potential customers. Further, as competition increases in the local
telecommunications market, the Company anticipates that general pricing
competition and pressures will increase significantly. If LECs lower their
rates, other telecommunications providers may be forced by market conditions to
charge less for their services in order to compete, which could have a material
adverse effect on the Company's financial condition, results of operations and
cash flow.
 
    The Company also may face competition in the provision of local
telecommunications services from cable companies, electric utilities, LECs
operating outside their current local service areas, long distance carriers and
start-up telecommunications ventures. The great majority of these entities
provide transmission services primarily over fiber-optic, copper-based or
microwave networks, which enjoy proven market
 
                                       37
<PAGE>
acceptance for the transmission of telecommunications traffic. Moreover, the
consolidation of telecommunications companies and the formation of strategic
alliances within the telecommunications industry, which are expected to
accelerate as a result of the enactment of the 1996 Telecommunications Act,
could give rise to significant new or stronger competitors. The 1996
Telecommunications Act contains several provisions that bear directly on
wireless service providers such as the Company including provisions that entitle
wireless carriers to obtain interconnection from LECs, eliminate equal access
obligations with respect to wireless services, limit the ability of state and
local governments to discriminate against or prohibit certain wireless services
and allow BOC affiliates and large long distance carriers to bundle local and
long distance services with wireless offerings. Currently, the FCC is
implementing the provisions of the 1996 Telecommunications Act and several of
the FCC's decisions already are being challenged, thus the Company cannot at
this time predict the extent to or manner in which the 1996 Telecommunications
Act will affect the Company's business. The Company's strategy is to provide
local carrier services only where such services are part of a complete
telecommunications solution or where, because of the Company's early market
acceptance, it can offer services at competitive rates. There can be no
assurance that the Company will be able to compete effectively in the local
service markets. See "Risk Factors--Risks Associated with Entry into Local Phone
Service Market and Other New Markets."
 
    INTERNATIONAL AND FOREIGN MARKET SERVICES.  The Company offers
telecommunications service to and from remote and difficult-access locations
outside of the United States for its customers. Such services include the
provision of telecommunications services between domestic corporate offices and
remote sites. Therefore, the Company has not competed in a full range of
services with the incumbent telecommunications providers in a particular country
and has faced competition from international telecommunications providers
generally and others who provide telecommunications services to remote and
difficult-access locations. The Company provides private-line telecommunications
services in Russia. In Russia, the major competitors for networks are SOVAMTEL,
ROSTELECOM, AMRUSCOM and Global One. Although the Company believes that its
alliance with ITAR-TASS will allow it to compete favorably in Russia, there can
be no assurance that such alliance will continue on favorable terms to the
Company, if at all. In Russia, as well as in each other country where the
Company elects to compete, the Company may have to compete with the incumbent
service providers, which may have substantially greater financial resources,
governmental support both financially and otherwise, greater installed
infrastructure, long-standing relationships with their customers, favorable
governmental regulations, better understanding of local business practices and
customers and no foreign currency risks. Additionally, to the extent these
foreign markets are identified by the Company, they may be identified by other
companies that have significantly greater financial and other resources than the
Company. As a result, there can be no assurance that the Company will be able to
compete effectively in these markets. See "--Strategic Relationships and
Alliances" and "Risk Factors-- Competition" and "--Risks Associated with
International Operations."
 
GOVERNMENT REGULATION
 
    UNITED STATES.  In the United States, the Company's services are subject to
the 1934 Communications Act, the 1996 Telecommunications Act and the FCC
regulations thereunder, as well as the applicable laws and regulations of the
various states and state PSCs. Generally, the FCC exercises jurisdiction over
all facilities of, and services offered by, telecommunications common carriers
to the extent such services involve interstate or international communications,
while state regulatory authorities retain jurisdiction over intrastate
communications. The FCC also regulates the licensing and use of the
electromagnetic spectrum (I.E., wireless services) pursuant to Title III of the
1934 Communications Act.
 
    FEDERAL REGULATION
 
    FCC REGULATION OF WIRELESS LICENSES:  The Company holds numerous radio
station licenses which are subject to FCC regulation pursuant to Title III of
the 1934 Communications Act. The FCC regulates the
 
                                       38
<PAGE>
licensing, construction, operation, acquisition and sale of the Company's
wireless facilities and services, including the Company's microwave, satellite
earth station and land mobile systems. In recent years, Congress and the FCC
have made significant changes in the regulation of the wireless industry in
order to promote competition and expand the scope of services that wireless
service providers can offer.
 
    Facilities licensed by the FCC to provide microwave, satellite earth station
and land mobile service are subject to a variety of licensing, operational and
technical requirements specific to each service. Among other requirements,
licensees seeking to continue operating beyond the expiration date of the
licenses must renew their authority. FCC rules also impose prior approval
requirements on proposed transfers of control or frequency assignments. The FCC
continues to refine its wireless rules for each service area to accommodate
advances in technology, developing markets and new service arrangements, and to
eliminate confusing, outdated, redundant or otherwise burdensome regulation. The
outcome of FCC regulatory activities or decisions affecting wireless services
cannot be predicted and, therefore, there can be no assurances that FCC actions
or decisions in this area will not limit the Company's services or plans or have
a material adverse effect upon the Company's financial condition, results of
operations and cash flow.
 
    The 1996 Telecommunications Act contains several provisions that bear
directly on wireless service providers including provisions that entitle
wireless carriers to obtain interconnection from LECs, eliminate equal access
obligations with respect to wireless services, limit the ability of state and
local governments to discriminate against or prohibit certain wireless services
and allow BOC affiliates and long distance carriers, including the Company, to
bundle local and inter-LATA (local access and transport area) services with
wireless offerings. Currently, the FCC is implementing the provisions of the
1996 Telecommunications Act and several of the FCC's decisions already are being
challenged. Thus, the Company cannot at this time predict the extent to which
the 1996 Telecommunications Act will affect the Company's wireless business.
 
    TWO-WAY RADIO:  The FCC regulates the Company's two way business radio
systems under Part 90 of the FCC's rules and regulations. Business radio service
providers traditionally have been regulated by the FCC as private carriers
subject to minimal regulation in comparison to other wireless common carriers,
such as cellular service providers. However, the Omnibus Budget Reconciliation
Act of 1993, which amended the 1934 Communications Act, mandated regulatory
parity for "commercial mobile radio services" ("CMRS"), later defined by the FCC
to include business radio services that offer customers for-profit
interconnected service. Accordingly, the FCC reclassified for-profit business
radio systems that are interconnected to the public switched network as a common
carrier service, thereby imposing certain common carrier obligations on the
providers. Effective in October 1996, the FCC's rules permitted CMRS providers,
such as the Company, including for-profit interconnected business radio
services, to provide fixed wireless service in their assigned spectrum blocks on
a co-primary basis with mobile services. The Company's licenses are also subject
to various operational, technical and filing requirements, including
requirements that Company renew its licenses and seek prior approval of
transfers of control and frequency assignments.
 
    MICROWAVE SERVICES:  The Company holds various common carrier and private
microwave licenses. The FCC regulates fixed common carriers' microwave services
under Part 21 of its rules and regulations and private carriers under Part 94 of
its rules and regulations. Generally, a common carrier microwave service
provider offers services indifferently to all potential users, whereas a private
carrier's provision of telecommunications services is limited to the
transmission of its own internal communications or its customers' private
communications. Under the FCC's rules, private microwave carriers are not
permitted to transmit common carrier services over their network. IWL's
microwave licenses are subject to various operational, technical and filing
requirements, including requirements that the Company renew its licenses prior
to their expiration and seek prior approval of transfers of control or frequency
assignments.
 
    SATELLITE EARTH STATIONS:  The Company holds various earth station licenses.
The FCC regulates earth stations and VSAT (very small aperture terminal)
facilities and services under Part 25 of the FCC's rules
 
                                       39

and regulations. The Company's earth station and VSAT authorizations permit the
Company to provide both domestic and international voice and data services. The
Company provides service between the U.S. and Bosnia pursuant to its private
carrier earth station license. Effective April 11, 1996, the FCC revised its
"Separate Satellite Systems" and "Transborder Policies" governing U.S.-licensed
domestic and international satellites. As a part of its change in policy for
satellite space stations, the FCC eliminated certain licensing restrictions on
earth stations making it easier for U.S. earth stations to communicate both with
U.S. domestic satellites and certain international satellites such as PanAmSat,
Orion and Columbia Communication's TDRSS satellites. The FCC recently amended
the VSAT licensing and other satellite service rules in an effort to clarify and
streamline satellite service regulations. These rule changes and other
regulatory actions and decisions may permit earth station licensees such as the
Company greater flexibility in providing satellite earth station services. The
Company's licenses are subject to various operational, technical and filing
requirements, including renewal and prior transfer approval requirements.
 
    DOMESTIC WIRELINE SERVICE REGULATION:  As a common carrier offering
interstate long distance telephone service to the public, the Company is subject
to additional FCC regulation. As a common carrier, the Company is obligated to
offer service on a non-discriminatory basis at just and reasonable rates. The
FCC has sought generally to minimize regulations that apply to nondominant
carriers such as the Company, and thus domestic regulation of such carriers'
long distance service occurs primarily through the FCC's complaint procedures.
Until recently, carriers such as the Company have been required to file tariffs
with the FCC containing the rates, terms and conditions of interstate service.
Pursuant to a recent FCC order, as of December 1997, nondominant carriers will
no longer be able to file tariffs with the FCC with respect to their long
distance services. Such carriers will, however, be required to maintain at their
offices, and to provide to customers or regulators upon request, information
concerning their long distance services. An appeal of the FCC order eliminating
tariffs has been submitted to the U.S. Court of Appeals for the District of
Columbia and a motion to that Court requesting stay of the FCC's detariffing
order is pending. There can be no assurance of whether the appeal or stay will
be successful, or if successful, what effect such decisions may have on the
Company. However, if detariffing ultimately takes effect, the Company, like
other long distance companies, would likely incur additional costs in
establishing legally binding relationships with customers.
 
    The 1996 Telecommunications Act is intended to remove the formal barriers
between the long distance and local telecommunications services markets allowing
service providers from each market (as well as providers of cable television and
other services) to compete in all telecommunications markets. LECs are now
required to permit interconnection to their networks and satisfy obligations
with respect to unbundled access, resale, number portability, dialing parity,
access to rights-of-way, mutual compensation and other matters. In addition, the
legislation codifies the LECs' equal access and nondiscrimination obligations
and preempts inconsistent state regulation. As required by the legislation, the
FCC is conducting a large number of proceedings to adopt rules and regulations
to implement the new statutory provisions and requirements. In August 1996, the
FCC adopted new rules implementing certain provisions of the 1996
Telecommunications Act (the "Interconnection Orders"). These rules are designed
to implement the pro-competitive, deregulatory national policy framework of the
new statute by removing or minimizing the regulatory, economic and operational
impediments to competition for facilities-based and resold local services,
including switched local exchange service.
 
    Among other things, the Interconnection Orders establish rules requiring
incumbent LECs to interconnect with new entrants such as the Company at
specified network points; require incumbent LECs to provide carriers with
nondiscriminatory access to network elements on an unbundled basis at any
technically feasible point at rates that are just, reasonable and
nondiscriminatory; establish rules requiring incumbent LECs to allow
interconnection via physical and virtual collocation; require the states to set
prices for interconnection, unbundled elements, and termination of local calls
that are nondiscriminatory and cost-based using a forward looking methodology
which excludes embedded costs but allows a reasonable cost-of-capital profit;
require incumbent LECs to offer for resale any telecommunication
 
                                       40
<PAGE>
service that the carrier provides at retail to end users at prices to be
established by the states but which generally are at retail prices less
reasonably avoidable costs; and require LECs and utilities to provide new
entrants with nondiscriminatory access to poles, ducts, conduit and
rights-of-way owned or controlled by LECs or utilities. Exemptions to some of
these rules are available to LECs which qualify as rural LECs under the 1996
Telecommunications Act. The Interconnection Orders also require that intra-LATA
presubscription (pursuant to which LECs must allow customers to choose different
carriers for intra-LATA toll service without having to dial extra digits) be
implemented no later than February 1999; that LECs provide new entrants with
nondiscriminatory access to directory assistance services, directory listings,
telephone numbers and operator services; and that LECs comply with certain
network disclosure rules designed to ensure interoperability of multiple local
switched networks.
 
    Petitions seeking reconsideration of one or more aspects of the
Interconnection Orders have been filed with the FCC and are pending and various
appeals of the Interconnection Orders have been consolidated into proceedings
currently pending before the U.S. Eighth Circuit Court of Appeals. Certain of
the rules adopted in the Interconnection Orders, including rules that concern
the pricing of interconnection, have been stayed by the Court. There can be no
assurance of how the Interconnection Orders will be implemented or enforced or
to what effect they will have on competition within the telecommunications
industry generally or on the competitive position of the Company specifically.
 
    Other matters addressed by the 1996 Telecommunications Act may affect the
Company's operations. For example, as required by the 1996 Telecommunications
Act, a joint board of federal and state regulators was convened to consider
possible changes to the FCC's existing universal service support mechanisms
designed to ensure that affordable telephone service is available to all
consumers. In November 1996, the FCC initiated a proceeding to examine universal
service issues, and has received comment on the proposals set forth by the joint
board. Access charge reform also may significantly affect the Company. Access
charges are charges imposed by LECs on long distance providers for access to the
local exchange network, and were designed to compensate the LEC for its
investment in the local network. As required by the 1996 Telecommunications Act,
in December 1996 the FCC issued an order which, among other things, requests
comment on a number of interstate access charge reform issues designed to foster
efficient pricing of access, competition for access services, and to reflect the
development for local services prompted by the 1996 Telecommunications Act. The
FCC has also sought comment on whether Internet service providers and other
information service providers should be subject to access charges.
 
    The legislation also contains special provisions that eliminate the
restrictions on the BOCs and GTOCs from providing long distance services. These
new provisions permit a BOC to enter the "out-of-region" long distance market
immediately upon the receipt of any state or federal regulatory approvals
otherwise applicable to the provision of long distance service. These new
provisions also permit a BOC to enter the "in-region" long distance market if it
satisfies procedural and substantive requirements, including obtaining FCC
approval upon a showing that in certain situations facilities-based competition
is present in its market, and that it has entered into interconnection
agreements which satisfy a 14-point "checklist" of competitive requirements. The
GTOCs are permitted to enter the long distance market immediately without regard
to limitations by region, although necessary regulatory approvals to provide
long distance services must be obtained, and the GTOCs are subject to the
provisions of the 1996 Telecommunications Act that impose interconnection and
other requirements on LECs. The 1996 Telecommunications Act also imposes certain
restrictions on the BOCs' entry into long distance services, including a
separate subsidiary requirement and joint marketing restrictions.
 
    There can be no assurance of how the 1996 Telecommunications Act will be
implemented or enforced or the effect it will have on competition within the
telecommunications industry generally or on the competitive position of the
Company specifically.
 
    INTERNATIONAL SERVICE REGULATION:  International common carriers, such as
the Company, are required to obtain authority under Section 214 of the 1934
Communications Act and file a tariff containing the
 
                                       41
<PAGE>
rates, terms and conditions applicable to their services prior to initiating
their international telecommunications services. The Company has obtained
authorization from the FCC to resell the switched capacity of several underlying
carriers to provide international message telecommunications services. Under
recently-revised FCC rules, the Company has sought even broader global authority
from the FCC to provide resold and facilities-based international private line
and switched service to virtually every foreign point in the world. This
application will be processed under streamlined procedures at the FCC. The
Company intends to file an application for authority to use foreign-licensed
facilities that are not covered by the streamlined application for global
authority.
 
    Under current tariff rules applicable to international carriers, nondominant
international carriers such as the Company must file their international tariffs
and any revisions thereto with one day's notice. The Company has filed an
international tariff for switched services with the FCC. Additionally,
international telecommunications service providers are required to file copies
of their contracts with other carriers, including correspondent agreements, with
the FCC within 30 days of execution. The FCC's rules also require the Company to
file periodically a variety of reports regarding its international traffic flows
and use of international facilities.
 
    The Company also must conduct its international business in compliance with
the FCC's international settlements policy. The FCC's international settlements
policy establishes the permissible boundaries for U.S. facilities-based carriers
and their foreign correspondents to settle the cost of terminating each other's
traffic over their respective networks. The amount of payments (the "settlement
rate") is determined by the negotiated accounting rate specified in the
correspondent agreement. Under the FCC's international settlements policy,
unless prior approval is obtained, the settlement rate generally must be
one-half of the accounting rate. Carriers must obtain waivers of the FCC's rules
if they wish to use an accounting rate that differs from the prevailing rate or
vary the settlement rate from one-half of the accounting rate. As a result of
the FCC's pro-competition policies, the recent trend has been toward reduction
in the accounting rate.
 
    The FCC recently revised its rules to permit more flexibility in its
international settlements policy as a method of achieving lower cost-based
accounting rates as more competition is introduced in foreign markets and
proposed new rules to lower the price of providing international services. These
and other changes may provide more flexibility to the Company and its
competitors to respond more rapidly to changes in the global telecommunications
market. The Company intends, where possible, to take advantage of lowered
accounting rates and flexible arrangements. The Company cannot predict how the
FCC will resolve pending international policy issues or how such resolution will
affect its international business.
 
    FOREIGN OWNERSHIP LIMITATIONS:  The 1934 Communications Act limits the
ownership of an entity holding a common carrier radio license by non-U.S.
citizens, foreign corporations and foreign governments. The 1934 Communications
Act provides that non-U.S. citizens, foreign governments or their
representatives or corporations organized under the laws of a foreign country
may not own in the aggregate more than 20% of a company holding common carrier
radio licenses or no more than 25% of the parent of a common carrier radio
licensee if the FCC determines that the public interest would be served by
prohibiting such ownership. If the Company's foreign ownership were to exceed
the limits set forth in the 1934 Communications Act, the FCC could impose a
range of penalties on the Company, including fines and/or revocation or
divestiture of its licenses.
 
    The FCC recently adopted new rules relating to the entry and participation
of foreign entities in the U.S. telecommunications market. The Company holds FCC
authority to provide international services and therefore is subject to the
FCC's rules on foreign affiliations. Under those rules, the FCC will scrutinize
an ownership interest greater than 25%, or a controlling interest at any level,
in a U.S. carrier by a dominant foreign carrier, to determine whether the
destination market of the foreign carrier offers "effective, competitive
opportunities" ("ECO"). The FCC imposes the same ECO test and affiliation
standard on U.S.-based carriers that invest in dominant foreign carriers. The
FCC may impose restrictions on affiliated carriers not meeting the ECO test. The
new rules also require international carriers to notify the FCC
 
                                       42
<PAGE>
60 days in advance of an acquisition of a 10% or greater interest by a foreign
carrier in that U.S. carrier. The FCC has discretion to determine that unique
factors require application of the ECO test or a change in regulatory status of
the U.S. carrier even though the foreign carrier's interest is less than 25%.
 
    Regulation of the telecommunications industry is changing rapidly. The FCC
is considering a number of international service issues in the context of
several policy rulemaking proceedings and in response to specific petitions and
applications filed by other international carriers. The FCC's resolution of some
of these issues in other proceedings may adversely affect the Company's
international business (by, for example, permitting larger carriers to take
advantage of accounting rate discounts for high traffic volumes). The Company is
unable to predict how the FCC will resolve the pending international policy
issues or how such resolution will affect its international business. There can
be no assurance that future regulatory changes will not have a material adverse
impact on the Company's financial condition, results of operations and cash
flow.
 
    REGULATORY OVERSIGHT:  The FCC imposes a variety of reporting and annual fee
requirements. The FCC and the state regulatory agencies with jurisdiction over
the Company and its services have discretion to, among other things, impose
fines, conditions or revoke the Company's authority to the extent that such
agencies find that the Company has violated regulatory requirements, including
the requirement to pay the required fees or the FCC's restrictions on the use of
private lines for providing switched services. The FCC also has authority to
address violations of the foreign ownership limitation, by, among other things,
requiring divestiture or restructuring of the Company's radio station licenses.
 
STATE REGULATION
 
    Some of the Company's services may be classified as intrastate and therefore
subject to state regulation. Such services are regulated by the applicable
individual state PSCs. Governing regulations at the state level differ from
state to state and, sometimes, by the telecommunications service provided. The
majority of states require carriers to apply for certification to provide
intrastate telecommunications service. The Company has sought and obtained
authority to provide long distance service in Texas and to provide high capacity
dedicated services in Louisiana. The Company also serves customers located in
other states. To the extent that such services can be interpreted to be
intrastate in nature, the Company would be required to obtain the appropriate
certification or other authority from the relevant PSC. If any state PSC were to
conclude that the Company is or was providing intrastate service without the
appropriate authority, the PSC could initiate enforcement actions, which could
include, but need not be limited to, the imposition of fines or the refusal to
grant the regulatory authority necessary for the future provision of intrastate
telecommunications services. Although the Company intends to obtain operating
authority in each jurisdiction in which such authority is required, there can be
no assurance that one or more jurisdictions will not deny the Company's request
for operating authority. It is possible that any adverse PSC action would have a
material adverse effect on the Company.
 
    PSCs also regulate access charges and other pricing for telecommunications
services within each state. The BOCs and other local exchange carriers have been
seeking reduction of state regulatory requirements, including greater pricing
flexibility. If regulations are changed to allow variable pricing of access
charges based on volume, the Company could be placed at a competitive
disadvantage over larger long distance carriers. The Company also could face
increased price competition from the BOCs and other local exchange carriers for
intra-LATA and inter-LATA long distance services, which competition may be
increased by the removal of former restrictions on long distance service
offerings by the BOCs as a result of the 1996 Telecommunications Act. The impact
of such rule changes on the Company cannot be predicted.

EMPLOYEES
 
    As of December 31, 1996, the Company employed approximately 134 people,
including approximately 20 in selling and marketing, 85 in engineering and
technical services and 29 in management, administration and finance. None of the
Company's employees is represented by a labor union or is subject to a
collective bargaining agreement. The Company believes that its relations with
its employees are good.
 
FACILITIES
 
    The Company owns an office building in Friendswood, Texas and Lafayette,
Louisiana and leases additional space in Friendswood and Houston, Texas, New
Orleans, Louisiana and Moscow, Russia. The Company considers its current
facilities adequate for its current needs and believes that suitable additional
space will be available, as needed, to accommodate further physical expansion of
corporate operations and for additional sales and service.
 
COMPANY LICENSES AND CERTIFICATIONS
 
    The Company has owned and maintained a variety of telecommunications
infrastructures and holds many FCC and international licenses to transmit voice
and data. FCC licenses issued to the Company allow it to provide radio and land
mobile, microwave and satellite communications services. The Company currently
holds 35 FCC licenses, with approximately 320 frequency pairs, for commercial
mobile radio service, which provides two-way wireless radio services along the
Texas and Louisiana Gulf Coast region
and offshore to oil and gas related companies. Each frequency pair allows
two-way transmission and reception. The Company holds six point-to-point
microwave FCC licenses providing voice and data services along the Texas and
Louisiana Gulf Coast region and offshore to drilling, production and related
companies. The Company holds and operates seven Ku band and two C band fixed
earth stations and holds FCC licenses that allow the Company to locate earth
stations in Texas and other U.S. locations.
 
    The Company operates as a FCC licensed 214 carrier to provide resold
switched telecommunications services. The Company currently provides
international facilities-based private line service on a private carrier basis
into Bolivia, Bosnia, Croatia, Ecuador, Hungary and Russia. The Company recently
installed a Class 4 tandem switch and value-added services platform at its
facility in Houston, Texas as part of its new point-of-presence ("POP") for its
IWL Connect-TM- division. As part of the Company's plans to install fiber optic
cable and wireless infrastructure, the Company has received CAP certification
and authority to operate from the States of Louisiana and Texas, and has
obtained a Service Provider Certificate of Operating Authority from the State of
Texas, which qualifies the Company as a CLEC in Texas. The Company has applied
for CLEC status in Louisiana, which the Company expects to receive by the fourth
quarter of fiscal 1997. In addition, the Company has been approved to have pole
attachment rights to existing or future facilities of Entergy, BellSouth and the
State of Louisiana. Pole attachment rights allow the Company to attach its own
fiber optic cable to such parties' utility poles.

DIRECTOR COMPENSATION
 
    Non-employee directors of the Company of the Board of Directors will be paid
$1,000 per meeting for attending or participating in meetings of the Board of
Directors or any committee thereof, and receive reimbursement for out-of-pocket
expenses incurred for attendance at meetings. Non-employee directors will also
receive non-statutory stock options under the 1997 Director Option Plan. See
"--Benefit Plans-- 1997 Director Stock Option Plan." The Company's policy is not
to pay any additional compensation to employees of the Company for their
services as a director.
 
LIMITATION OF LIABILITY
 
    As permitted by the Texas Business Corporation Act, the Company's Restated
Articles of Incorporation provide that the directors of the Company shall not be
liable to the Company or its shareholders for monetary damages for an act or
omission in the director's capacity as a director, except that such provision
does not authorize the elimination or limitation of liability of a director to
the extent the director is found liable for (i) a breach of the director's duty
of loyalty to the Company or its shareholders, (ii) any act or omission not in
good faith or that constitutes a breach of duty of the director to the Company
or an act or omission that involves intentional misconduct or a knowing
violation of law, (iii) any transaction from which the director derived any
improper personal benefit, whether or not the benefit resulted from an action
taken within the scope of the director's office or (iv) any act or omission for
which the liability of the director is expressly provided by statute.
 
    As a result of this provision, the Company and its shareholders may be
unable to obtain monetary damages from a director for breach of the duty of
care. Although shareholders may continue to seek injunctive or other equitable
relief for an alleged breach of fiduciary duty by a director, shareholders may
not have any effective remedy against the challenged conduct if equitable
remedies are unavailable.
 
    In addition, the Company's Restated Articles of Incorporation and Amended
and Restated Bylaws provide certain rights of indemnification for all officers
and directors.

(1) The fair market value of the Common Stock on June 30, 1996 was not more than
    $3.56 per share, as determined by the Board of Directors, which was also the
    exercise price payable for such shares.
 
(2) The Board of Directors has accelerated the vesting of all outstanding
    options granted under the Incentive Stock Option Plan effective upon
    completion of the Offering.
 
BENEFIT PLANS
 
    EMPLOYEE INCENTIVE STOCK OPTION PLAN.  Adopted on November 1, 1996 by the
Board of Directors and approved by the shareholders on December 8, 1996, the
Company's Incentive Stock Option Plan is intended to be an incentive for key
employees to continue to promote the best interests of the Company and enhance
its long-term performance and to provide an incentive for key employees to join
or remain with the Company. Options may be granted under the Incentive Stock
Option Plan to any person who is an officer or other executive personnel of the
Company.
 
    Options granted under the Incentive Stock Option Plan may be granted in the
form of options that qualify for treatment as "incentive stock options" (the
"Incentive Stock Options") under Section 422 of the Code and applicable
regulations and rulings promulgated thereunder. A total of 258,600 shares of
Common Stock have been reserved for issuance upon the exercise of options
granted under the Incentive Stock Option Plan. A total of 160,614 options have
been granted as of the date of this Prospectus at a weighted average exercise
price of $3.62 per share. The Company does not intend to grant any more options
under the Incentive Stock Option Plan due to the adoption of the 1997 Stock
Option Plan. The Incentive Stock Option Plan has terms substantially similar to
the 1997 Stock Option Plan described below.
 
    In February 1997, the Board of Directors determined that, effective upon
completion of the Offering, the vesting of all unvested options granted under
the Incentive Stock Option Plan would be automatically accelerated, without the
need for further action by the Board, so that all such options would become
fully vested and presently exercisable at such time.
 
    1997 STOCK OPTION PLAN.  Adopted in February 1997 by the Board of Directors
and the shareholders of the Company, the Company's 1997 Stock Option Plan is
intended to attract and retain the best available personnel for positions of
substantial responsibility, to provide additional incentives to employees and
consultants of the Company and any affiliates thereof and to promote the success
of the Company's business.
 
    Options to be granted under the 1997 Stock Option Plan may be either
Incentive Stock Options or non-statutory stock options under the Code. Incentive
Stock Options may be granted under the 1997 Stock Option Plan to any person who
is an officer or other employee (including officers and employees who are also
directors) of the Company or any of its subsidiaries. The exercise price of
Incentive Stock Options must be at least the fair market value of a share of the
Common Stock on the date of grant (and not less than 110% of the fair market
value in the case of an Incentive Stock Option granted to an optionee owning 10%
or more of the Company's Common Stock). A total of 300,000 shares of Common
Stock have been
 
                                       49
<PAGE>
reserved for issuance upon the exercise of options to be granted under the 1997
Stock Option Plan. No options have been granted as of the date of this
Prospectus under the 1997 Stock Option Plan.
 
    The 1997 Stock Option Plan is administered by the Company's Board of
Directors or a committee of the Board of Directors (the "Administrators"). Upon
completion of the Offering, the members of the Compensation Committee of the
Board will administer the 1997 Stock Option Plan. The Administrators have full
and final authority in their discretion, subject to the 1997 Stock Option Plan's
provisions (a) to determine the individuals to whom, and the time or times at
which, options shall be granted and the number of shares of Common Stock covered
by each option and (b) to construe and interpret the 1997 Stock Option Plan.
 
    Generally, options granted under the 1997 Stock Option Plan will be
exercisable at any time, and from time to time, throughout a five-year period
commencing on or after the date of grant in cumulative installments of 20% per
each year, or as otherwise specified by the Administrators and ending upon the
earliest of the expiration, cancellation, surrender or termination of the option
as provided in the 1997 Stock Option Plan. The Board of Directors may at any
time amend, alter, suspend or discontinue the 1997 Stock Option Plan, but no
amendment, alteration, suspension or discontinuation will be made that would
impair the rights of any optionee under any outstanding option grants without
the optionee's consent. In addition, to the extent necessary to comply with Rule
16b-3 or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of the NASD), the Company will obtain
shareholder approval of any plan amendment as required. The term of an option
may not exceed ten years. Upon dissolution or liquidation of the Company, each
outstanding option will terminate. In the event of a proposed sale of all or
substantially all of the assets of the Company or upon certain mergers where the
shareholders of the Company receive cash or securities of another issuer, or any
combination thereof, the options will be assumed by the successor entity or
substituted with an equivalent option.
 
    1997 DIRECTOR STOCK OPTION PLAN.  The Company's 1997 Director Option Plan
was adopted in February 1997 by the Board of Directors and the shareholders of
the Company to encourage ownership of the Company by eligible non-employee
directors of the Company whose continued services are considered essential to
the Company's future progress and to provide them with a further incentive to
remain as directors of the Company. All options to be granted under the 1997
Director Option Plan will be non-qualified and not eligible for treatment as
Incentive Stock Options under Section 422 of the Code. A total of 100,000 shares
of Common Stock have been reserved for issuance under the 1997 Director Option
Plan.
 
    The 1997 Director Option Plan is administered by the Company's Board of
Directors. The Board of Directors has full and final authority in their
discretion, subject to the 1997 Director Option Plan's provisions (a) to
determine the individuals to whom, and the time or times at which, options shall
be granted and the number of shares of Common Stock covered by each option and
(b) to construe and interpret the 1997 Director Option Plan. The Company expects
that each new non-employee director of the Company, upon becoming a director,
will receive option grants that generally will vest one-third on the day
preceding the first annual meeting of shareholders of the Company held after the
date of grant and one-third on each of the two following anniversaries of that
date, so long as the director continues to serve as a director of the Company.
The Board will also have the authority to make additional option grants to
existing non-employee directors.
 
    Each option will expire ten years from the date of grant. Outstanding
options will expire earlier if an optionee terminates service as a director
before the end of the first ten-year term. If an optionee terminates service as
a director for any reason including disability or death, the option will
automatically expire 12 months after the date of termination, but in no event
after the ten-year term. Options are not assignable and may not be transferred
other than by will or the laws of descent and distribution. Upon a dissolution
or liquidation of the Company, each outstanding Option will terminate unless
otherwise provided by the Board of Directors. In the event of a proposed sale of
all or substantially all of the assets of
 
                                       50
<PAGE>
the Company or upon certain mergers where the shareholders of the Company
receive cash or securities of another issuer, the options will be assumed by the
successor entity or substituted with an equivalent option.
 
    The 1997 Director Option Plan provides that the Board of Directors may
suspend or discontinue the 1997 Director Option Plan or review or amend it in
any respect whatsoever. If required by Rule 16b-3 under the Exchange Act or any
Code or Nasdaq National Market requirements, the Board of Directors will not
amend or terminate the 1997 Director Option Plan without shareholder approval.
No such termination will affect the terms of any options outstanding at that
time.
 
    401(K) PLAN.  Effective November 1, 1991, the Company established a
Retirement and Savings Plan (the "401(k) Plan"). The 401(k) Plan is a defined
contribution plan qualified under Section 401(a) of the Code that provides for
employee pre-tax contributions pursuant to Section 401(k) of the Code and both
matching and profit-sharing Company contributions. Eligible participants may
contribute, on a pre-tax basis through payroll deduction, between 1% and 15% of
their salary to a maximum of $9,500 in 1997. The Company has reserved the right
to amend or terminate the 401(k) Plan at any time. The Company matches 25% of
the first 6% of the employee's contribution, up to a maximum 1 1/2% of the
employee's contribution.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    During its fiscal year ended June 30, 1996, the Company had no Compensation
Committee or other committee of the Board of Directors performing similar
functions, and, accordingly, the Board of Directors determined the compensation
for the executive officers and related matters. Ignatius W. Leonards, as the
sole director of the Company during the last fiscal year, conducted all
deliberations of the Board of Directors concerning executive officer
compensation. However, Mr. Leonards, with respect to determinations regarding
his own compensation, relied on recommendations made by Byron M. Allen, the
Company's President. During such fiscal year, no executive officer of the
Company served as a member of the board of directors or compensation committee
of any entity that has one or more executive officers serving as a member of the
Company's Board of Directors. Effective upon consummation of the Offering, the
Board of Directors will have a Compensation Committee, of which Mr. Amenson and
the other non-employee director to be appointed by the Company following
completion of the Offering will be the initial members.
 
    Byron M. Allen, the Company's President and a director, lent the Company
$150,000 in September 1994 evidenced by a promissory note payable to Mr. Allen
bearing interest at the rate of 10% per annum. During the fiscal year ended June
30, 1995, Mr. Allen lent the Company an additional $100,000 evidenced by a
promissory note payable to Mr. Allen bearing interest at the rate of 2% per
annum in excess of Mr. Allen's cost of funds in his margin account at his
brokerage firm. The full amount of the notes, together with interest thereon,
was repaid by the Company in December 1995.
 
    Caroline Fontenot, the sister of Mr. Leonards, the Company's Chairman of the
Board and Chief Executive Officer, lent the Company $75,000 on June 1, 1992, of
which an outstanding balance of $47,680, bearing interest at the rate of 12% per
annum, remained as of December 31, 1996.

    Since the beginning of the Company's 1994 fiscal year, the Company has
entered into the various transactions with officers, directors and affiliates of
the Company described below.
 
    Byron M. Allen, the Company's President and a director, lent the Company

PRINCIPAL SHAREHOLDERS, DIRECTORS AND OFFICERS
 
    The following table sets forth certain information regarding the beneficial
ownership of the Company's Common Stock as of February 28, 1997 and as adjusted
to reflect the sale of the Common Stock offered by this Prospectus, by (i) each
person who is known by the Company to own beneficially more than 5% of the
Company's outstanding Common Stock, (ii) each of the Company's Named Executive
Officers and directors, and (iii) all of the current executive officers and
directors of the Company as a group. The information contained in this table
with respect to beneficial ownership reflects "beneficial ownership" as defined
in Rule 13d-3 under the Exchange Act. Shares of Common Stock not outstanding but
deemed beneficially owned by virtue of the right of an individual or group to
acquire shares within 60 days after February 28, 1997 are treated as outstanding
only when determining the amount and percentage of Common Stock owned by such
individual or group. Except as otherwise noted or pursuant to community property
laws, each person has sole voting and sole investment power with respect to the
shares shown. The address of each person listed is 12000 Aerospace Avenue, Suite

                          DESCRIPTION OF CAPITAL STOCK
 
    Upon the consummation of the Offering, the Company's authorized capital
stock will consist of 100,000,000 shares of Common Stock, par value $.01 per
share, and 10,000,000 shares of Preferred Stock, par value $.01 per share.
 
COMMON STOCK
 
    As of February 28, 1997, there were 2,227,816 shares of Common Stock issued
and outstanding, and held of record by four shareholders. There will be
3,477,816 shares outstanding after giving effect to the sale of shares of Common
Stock offered hereby (3,665,316 if the Underwriters' over-allotment option is
exercised in full). The holders of Common Stock are entitled to one vote per
share on all matters submitted to a vote of the shareholders. Cumulative voting
of shares of Common Stock is prohibited, which means that the holders of a
majority of shares voting for the election of directors can elect all members of
the Board of Directors. Except as otherwise required by applicable law, a
majority vote is sufficient for any act of shareholders. The holders of Common
Stock are entitled to receive ratably such dividends, if any, as may be declared
from time to time by the Board of Directors out of funds legally available
therefor, subject to the payment of any preferential dividends with respect to
any Preferred Stock that from time to time may be outstanding. In the event of
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior distribution rights of the holders of any
outstanding Preferred Stock. The holders of Common Stock have no preemptive or
conversion rights or other subscription rights, and there are no redemption or
sinking fund provisions applicable to the Common Stock. All of the outstanding
shares of Common Stock are fully paid and nonassessable, and all of the shares
of Common Stock offered hereby, when issued, will be fully paid and
nonassessable.
 
PREFERRED STOCK
 
    The Board of Directors has the authority to issue up to 10,000,000 shares of
Preferred Stock in one or more series and to fix the designations, relative
powers, preferences, rights, qualifications, limitations and restrictions of all
shares of each of such series, including, without limitation dividend rates,
preemptive rights, conversion rights, voting rights, redemption and sinking fund
provisions, liquidation preferences and the number of shares constituting each
such series, without any further vote or action by the shareholders. The
issuance of Preferred Stock could decrease the amount of earnings and assets
available for distribution to holders of Common Stock or adversely affect the
rights and powers, including voting rights, of the holders of Common Stock. The
issuance of Preferred Stock could also have the effect of delaying, deferring or
preventing a change in control of the Company, including transactions in which
the shareholders might otherwise receive a premium for their shares over the
then current market price, and may adversely affect the market price of the
Common Stock. At present, the Company has no plans to issue any shares of
Preferred Stock.
 
REPRESENTATIVE'S WARRANT
 
    The Company has agreed to sell to the Representative or its designees, for
nominal consideration, the Representative's Warrant to purchase up to 125,000
shares of Common Stock at an exercise price of equal to 120% of the initial
price of the Common Stock being offered hereby to the public. The Representative
has certain demand and "piggy-back" registration rights that may require the
Company to register for resale the shares of Common Stock issuable under the
Representative's Warrant. The Representative's Warrant is exercisable for a
period of four years, beginning one year from the date of this Prospectus. See
"Underwriting."

CERTAIN ANTI-TAKEOVER MATTERS
 
    Upon the consummation of the Offering, there will be 96,522,184 authorized
and unissued shares of Common Stock and 10,000,000 authorized and unissued
shares of Preferred Stock. The existence of authorized but unissued Common Stock
and Preferred Stock may enable the Board of Directors to render more difficult
or to discourage an attempt to obtain control of the Company by means of a
merger, tender offer, proxy solicitation or otherwise. For example, if in the
due exercise of its fiduciary obligations, the Board of Directors were to
determine that a takeover proposal is not in the Company's best interest, the
Board of Directors could cause shares of Common Stock or Preferred Stock to be
issued without shareholder approval in one or more private offerings or other
transactions that might dilute the voting or other rights of the proposed
acquiror or insurgent shareholder or shareholder group or create a substantial
voting block in institutional or other hands that might undertake to support the
position of the incumbent Board of Directors. In this regard, the Company's
Restated Articles of Incorporation grant the Board of Directors broad power to
establish the rights, preferences and privileges of authorized and unissued
Preferred Stock without shareholder approval. The issuance of shares of
Preferred Stock pursuant to the Board of Director's authority described above
could decrease the amount of earnings and assets available for distribution to
holders of Common Stock or adversely affect the rights and powers, including
voting rights, of such holders. The issuance of Common Stock or Preferred Stock
could also have the effect of delaying, deferring or preventing a change in
control of the Company, including transactions in which the shareholders might
otherwise receive a premium for their shares over the then current market price,
and may adversely affect the market price of the Common Stock. The Board of
Directors does not currently intend to seek shareholder approval prior to any
issuance of Common Stock or Preferred Stock, unless otherwise required by law.
 
    The Company is also subject to prior regulatory approval by the FCC and
various state regulatory agencies for a transfer of control of the Company or
for the assignment of the Company's intrastate certification authority and its
international authority. The 1934 Communications Act provides that non-U.S.
citizens, foreign governments or their representatives or corporations organized
under the laws of a foreign country may not own in the aggregate more than 20%
of a company that owns common carrier radio licenses such as the Company. In
addition, because the Company holds FCC authority to provide international
service, the FCC will scrutinize an ownership interest in the Company of greater
than 25%, or a controlling interest at any level, by a dominant foreign carrier.
International carriers, such as the Company, must notify the FCC 60 days in
advance of an acquisition of a 10% or greater interest by a foreign carrier in
such carriers. Furthermore, the Company's bank loan agreement provides that an
event of default thereunder will occur if all or a controlling interest in the
Company's capital stock is sold, assigned or otherwise transferred. Any of the
foregoing factors could have the effect of delaying, deferring or preventing a
change of control of the Company. See "--Preferred Stock" and
"Business--Government Regulation."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have outstanding 3,477,816
shares of Common Stock, assuming no exercise of options or warrants after the
date of this Prospectus. Of these shares, all 1,250,000 shares offered hereby
(1,437,500 shares if the Underwriters' over-allotment option is exercised in
full) will be freely tradeable in the public market without restriction unless
purchased by "affiliates" of the Company as that term is defined in Rule 144
under the Securities Act. The remaining 2,227,816 shares of Common Stock
outstanding upon completion of the Offering are "restricted securities" as that
term is defined in Rule 144.
 
    The executive officers and directors of the Company, who as of the date of
this Prospectus held an aggregate of 2,225,008 shares of Common Stock and
options to purchase an aggregate of 146,695 shares, all of which will be
currently exercisable upon closing of the Offering, have entered into lock-up
agreements (collectively, the "Lock-Up Agreements") with Cruttenden Roth
Incorporated pursuant to which such persons have agreed not to sell any of such
shares of Common Stock owned by such persons pursuant to Rule 144 under the
Securities Act or otherwise, without the prior written consent of Cruttenden
Roth Incorporated, for a period of one year from the date of this Prospectus.
Cruttenden Roth Incorporated has informed the Company that it does not intend to
reduce or eliminate the lock-up period except with respect to the sale of shares
by Mr. Leonards to Mr. Allen described in "Principal Shareholders."
 
    Upon expiration of the Lock-Up Period, approximately 2,225,008 additional
shares will be eligible for sale subject to the timing, volume and manner of
sale restrictions of Rule 144. The 2,808 remaining restricted shares held by an
existing shareholder will become eligible for sale at various times over a
period of less than one year. In addition, 13,919 shares subject to outstanding
vested stock options, if exercised, will become eligible for sale 90 days after
the effectiveness of the Offering and, upon expiration of certain Lock-Up
Agreements, an additional 146,695 shares subject to outstanding stock options
(including unvested options the vesting of which will become automatically
accelerated upon completion of the Offering), if exercised, will be eligible for
sale, in each case subject to the restrictions of Rule 701 unless sold pursuant
to an effective registration statement under the Securities Act.
 
    In general, under Rule 144 (as amended effective as of April 29, 1997), a
person (or persons whose shares are aggregated) who has beneficially owned
shares for at least one year, including persons who may be deemed to be
"affiliates" of the Company as that term is defined under Rule 144, would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of 1% of the then outstanding shares of the Company's Common
Stock (34,778 shares after the Offering) or the average weekly trading volume in
the Nasdaq National Market during the four calendar weeks preceding the date on
which the notice of the sale is filed with the SEC. Sales by affiliates and
beneficial owners of restricted securities held for less than two years may not
be made under Rule 144 until 90 days after the date of this Prospectus and are
subject to the foregoing volume limitations and to certain manner of sale
provisions, notice requirements and the availability of current public
information about the Company. However, a person who is not an affiliate of the
Company at any time within 90 days preceding a sale and who has beneficially
owned shares for at least two years would be entitled immediately, upon the date
of this Prospectus, to sell such shares under Rule 144(k) without regard to the
volume limitations, manner of sale provisions, notice and current public
information requirements. In general, Rule 701 permits resales of shares issued
pursuant to certain compensatory benefit plans and contracts commencing 90 days
after an issuer becomes subject to the reporting requirements of the Exchange
Act (which will occur upon completion of the Offering) in reliance upon Rule 144
but without compliance with certain restrictions, including the holding period
requirements, contained in Rule 144.
 
    The Company, which has granted outstanding options to acquire 160,614 shares
under the Incentive Stock Option Plan, does not intend to grant any additional
options under that plan. There are also (i) 300,000 shares of Common Stock
reserved for issuance under the 1997 Stock Option Plan
 
                                       56
<PAGE>
(ii) 100,000 shares of Common Stock reserved for issuance under the 1997
Director Option Plan and (iv) 125,000 shares of Common Stock subject to the
Representative's Warrant. The Company intends to file a registration statement
after the Offering on Form S-8 under the Securities Act to register the 560,614
shares of stock issuable under the Company's stock option plans. See
"Management--Benefit Plans." Shares issued upon exercise of options after the
effective date of such registration statement will be generally eligible for
sale in the open market, subject to expiration of certain Lock-Up Agreements. In
addition, the Representative has demand and "piggy-back" registration rights in
connection with the Representative's Warrant. Registration of such shares under
the Securities Act would result in such shares becoming freely tradeable without
restriction under the Securities Act (except for shares purchased by affiliates
of the Company) immediately upon the effective date of such registration. If
such holders, by exercising their demand registration rights, cause a large
number of securities to be registered and sold in the public market, such sales
could have an adverse effect on the market price for the Company's Common Stock.
If the Company were to include in a Company-initiated registration such shares
pursuant to the exercise of piggy-back registration rights, such sales may have
an adverse effect on the Company's ability to raise additional capital. The
Representative's Warrant may not be exercised until the first anniversary of the
date of this Prospectus. See "Description of Capital Stock--Representative's
Warrant" and "Underwriting."
 
    Prior to the Offering, there has been no public market for the Common Stock
of the Company. No prediction can be made as to the effect, if any, that future
sales of shares, or the availability of shares for future sales, will have on
the market price of the Common Stock. Sales of a substantial number of shares of
Common Stock in the public market following the Offering, or the perception that
such sales could occur, could adversely affect the market price of the Company's
Common Stock.

underwriting discounts and commissions set forth on the cover page of this

</TABLE>
 
    The Company has been advised by the Representative that the Underwriters
propose to offer the shares of Common Stock to the public at the public offering
price reflected on the cover page of this Prospectus and to selected securities
dealers at such price less a concession not exceeding $      per share. The
Underwriters may allow, and such dealers may reallow, a concession not exceeding
$      per share to other dealers. After the public offering of the shares of
Common Stock, the public offering price and other offering terms may be changed.
No change in such terms shall change the amount of proceeds to be received by
the Company as set forth on the cover page of this Prospectus.
 
    The Company has granted the Underwriters an over-allotment option,
exercisable during the 45-day period after the date of this Prospectus, to
purchase up to 187,500 additional shares of Common Stock at the public offering
price set forth on the cover page of this Prospectus less the underwriting
discounts and commissions. The Underwriters may exercise the over-allotment
option only to cover over-allotments in the sale of the Common Stock offered
hereby. If the Underwriters exercise the over-allotment option, the Underwriters
will purchase additional shares in approximately the same proportion as the
shares set forth in the above table.
 
    In connection with the Offering, the Company has agreed to issue to the
Representative the Representative's Warrant to purchase up to 125,000 shares of
Common Stock. The Representative's Warrant is exercisable for a period of four
years, beginning one year from the date of this Prospectus. The Representative's
Warrant is exercisable at an exercise price equal to 120% of the initial price
of the Common Stock being offered hereby to the public. The Representative's
Warrant is nontransferable for a period of one year following the date of this
Prospectus, except (i) to any of the Underwriters, or to individuals who are
either officers or partners of an Underwriter, or (ii) by will or the laws of
descent and distribution. The holders of the Representative's Warrant will have,
in that capacity, no voting, dividend or other shareholder rights. During the
exercise period, the Representative is entitled to certain demand and
"piggy-back" registration rights that may require the Company to register for
public resale the shares of Common Stock issuable under the Representative's
Warrant. The number of shares covered by the Representative's Warrant and the
exercise price thereof are subject to adjustment in certain events to prevent
dilution. Any profit realized by the Representative on the sale of securities
issuable upon exercise of the Representative's Warrant may be deemed to be
additional underwriting compensation.
 
                                       58
<PAGE>
    The Representative will also receive at the closing of the Offering a
nonaccountable expense allowance equal to 3% of the aggregate public offering
price of the shares of Common Stock sold in the Offering including proceeds from
the over-allotment option, if exercised. The Representative's expenses in excess
of the non-accountable expense allowance, including its legal expenses, will be
borne by the Representative. To the extent that the expenses of the
Representative are less than the non-accountable expense allowance, the excess
shall be deemed to be compensation to the Representative.
 
    The Representative has informed the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
    In addition, the Company has agreed to indemnify the Underwriters against
certain liabilities, including liabilities under the Securities Act, and to
contribute in certain events to any liabilities incurred by the Underwriters in
connection with the sale of shares of Common Stock.
 
    Prior to the Offering, there has not been a public market for the Common
Stock. The public offering price of the Company Stock has been determined by
arm's-length negotiation between the Company and the Representative. Among the
factors to be considered by the Company and the Representative in pricing the
Common Stock are prevailing market conditions, the results of operations,
current financial condition and future prospects of the Company, the experience
of management, the amount of ownership to be retained by present shareholders,
the general condition of the economy and the demand for similar securities of
companies considered comparable to the Company.
 
    The foregoing sets forth the material terms and conditions of the
Underwriting Agreement, but does not purport to be a complete statement of the
terms and conditions thereof. Copies of the Underwriting Agreement are on file
at the offices of the Representative, the Company and the SEC. See "Additional
Information."

Company by Munsch Hardt Kopf Harr & Dinan, P.C., Dallas, Texas. Certain legal
matters in connection with the Common Stock offered hereby will be passed upon

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
IWL Communications, Inc. and Subsidiaries:
 
    We have audited the accompanying consolidated balance sheets of IWL
Communications, Inc. and Subsidiaries (the Company) as of June 30, 1995 and
1996, and the related consolidated statements of operations, stockholders'
equity, and cash flows for each of the three years ended June 30, 1996. 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 audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
IWL Communications, Inc. and Subsidiaries as of June 30, 1995 and 1996 and the
results of their operations and their cash flows for each of the three years
ended June 30, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                     (INFORMATION FOR THE SIX MONTHS ENDED
                    DECEMBER 31, 1995 AND 1996 IS UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    NATURE OF BUSINESS
 
    The Company provides communications solutions to customers with operations
in remote, difficult-access regions and in areas around the world where
government deregulation has created new market opportunities. The Company
delivers communications services to its customers by utilizing a broad range of
analog and digital technologies, including satellite, microwave radio,
conventional two-way radio and fiber optic cable. The Company has operations in
Friendswood and Houston, Texas, New Orleans and Lafayette, Louisiana and Moscow,
Russia.
 
    BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of IWL
Communications, Inc. and its wholly-owned subsidiaries, Spacelink Systems, Inc.,
Spacelink Systems FSC, Inc. and IWL Communications Ltd. (Russia). All material
intercompany accounts and transactions have been eliminated. The Company's
investment in and operating results of Kenwood Systems Group, which is a 50%
owned entity, are included in the accompanying financial statements on the basis
of the equity method of accounting.
 
    CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
    CONCENTRATION OF CREDIT RISK
 
    The Company performs credit evaluations of its customers, but does not
require collateral.
 
    MAJOR CUSTOMERS AND SUPPLIERS
 
    For the year ended June 30, 1996, approximately $11,450,000 (41%) of the
Company's sales were from one customer. At June 30, 1996, accounts
receivable-trade included balances of approximately $2,346,000 and $561,000 from
two of the Company's major customers.
 
    The majority of these sales ($10,553,846) were attributable to a one-time
project, which includes a significant equipment resale component, that the
Company expects will be substantially completed in fiscal 1997 and, therefore,
is not expected to contribute in a material manner to the Company's revenue in
future periods.
 
    The Company purchases substantially all of its telecommunications equipment
for use in the oil and gas industry from one supplier pursuant to an exclusive
distributorship agreement.
 
    INVENTORY
 
    Inventory substantially consists of parts and equipment held for resale.
Inventory that can be specifically identified using a unique identification
number is stated at the lower of specific cost or market. Inventory that cannot
be specifically identified is stated at the lower of cost or market where cost
is determined using the first in-first out method. Market value, in all cases,
represents the lower of replacement cost or net realizable value.

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT/DEPRECIATION
 
    Property and equipment is stated at cost. Depreciation is computed using the
straight-line method over the estimated useful lives of the assets as indicated
below:
 
<TABLE>
<S>                                                               <C>
Buildings and improvements......................................  7-31 years
Vehicles........................................................     5 years
Furniture and fixtures..........................................   5-7 years
Leasehold improvements..........................................  Lease term
Equipment for rent/lease........................................  7-10 years
Computers, office and test equipment............................   5-7 years
</TABLE>
 
    Significant expenditures that add materially to the utility or useful lives
of property, plant and equipment are capitalized. All other maintenance and
repair costs are charged to current operations. The cost and related accumulated
depreciation of assets replaced, retired or otherwise disposed of are eliminated
from the property accounts and any gain or loss is reflected as other income and
expense.
 
    REVENUE RECOGNITION
 
    The Company provides services such as telecom and carrier services and land
mobile services whose revenue is recognized based on the monthly service
provided. Lease revenues from equipment rentals are recorded over the life of
the lease contract. Communication systems contracts are typically fixed price
and revenue is recognized based on the percentage-of-completion method.
 
    STOCK OPTION PLAN
 
    Prior to July 1, 1996, the Company accounted for its stock option plan in
accordance with the provisions of Accounting Principles Board (APB) Opinion No.
25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and related interpretations. As
such, compensation expense would be recorded on the date of grant only if the
current market price of the underlying stock exceeded the exercise price. On
July 1, 1996, the Company adopted SFAS No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION, which permits entities to recognize as expense over the vesting
period the fair value of all stock-based awards on the date of grant.
Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net income and pro forma
earnings per share disclosures for employee stock option grants made in 1995 and
future years as if the fair-value-based method defined in SFAS No. 123 had been
applied. The Company has elected to continue to apply the provisions of APB
Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No. 123
commencing in its June 30, 1997 financial statements.
 
    INCOME TAXES
 
    The Company uses the asset and liability method of accounting for income
taxes. Under this method, deferred tax assets and liabilities are determined
based on differences between financial reporting and tax bases of assets and
liabilities and are measured using the enacted tax rate and laws that will be in
effect when the differences are expected to reverse.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                     (INFORMATION FOR THE SIX MONTHS ENDED
                    DECEMBER 31, 1995 AND 1996 IS UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The provision for income taxes includes federal, foreign, state and local
income taxes currently payable and those deferred because of temporary
differences between the financial statement and tax bases of assets and
liabilities.
 
    ESTIMATES
 
    Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these financial statements in
conformity with generally accepted accounting principles. Actual results could
differ from those estimates.
 
    INTERIM FINANCIAL STATEMENTS
 
    The consolidated financial statements at December 31, 1996 and for the six
months ended December 31, 1995 and 1996 are unaudited. In the opinion of the
Company, the unaudited consolidated financial statements at December 31, 1996
and for the six months ended December 31, 1995 and 1996, include all
adjustments, consisting only of normal recurring adjustments necessary for a
fair presentation of the financial position and results of operations for such
periods. Results of operations for the six months ended December 31, 1996 are
not necessarily indicative of results to be expected for the full year.
 
    NET INCOME PER SHARE
 
    Net income per share is computed by dividing net income applicable to common
stock by the weighted average number of shares of common stock and common stock
equivalents outstanding, net of shares assumed to be repurchased using the
treasury stock method. Common stock equivalents arise from the assumed
conversion of outstanding stock options and warrants.
 
    On November 1, 1995, the Board of Directors declared a two hundred-for-one
common stock split effective November 1, 1995. All share amounts and numbers of
shares have been restated to reflect the stock split.

(9) LEASE CONTRACTS
 
    The Company provides telecommunications services to various customers under
operating leases with typical terms of one to five years. The services may
include communications equipment, line/satellite charges and/or maintenance
charges. These leases impose certain obligations on both the lessor and lessee
which must be met during the term of the lease.
 
    A significant portion of these services requires that the Company have
access to international communication satellites. The Company has contracted
with a Russian entity for rights to access its portion of an international
communications satellite. The Company has agreed to pay a recurring monthly fee
to the entity based on the amount of satellite space segment utilized by each
lessee. Additionally, the Company has sold communications equipment to the
entity. The Company utilizes those facilities to provide communication services
to various United States oil and gas companies and other customers doing
business in Russia.

authorized to fix the designations, relative powers, preferences, rights,
qualifications, limitations and restrictions of all shares of each of such
series, including without limitation dividend rates, preemptive rights,
conversion rights, voting rights, redemption and sinking fund provisions,
liquidation preferences and the number of shares constituting each such series,
without any further vote or action by the shareholders. Upon consummation of a
public offering of common stock, there will be 10,000,000 authorized and
unissued shares of preferred stock. The Company's Articles of Incorporation
grant the Board of Directors power to establish the rights, preferences and
privileges of authorized and unissued preferred stock. The issuance of shares of
preferred stock pursuant to the Board of Director's authority described above
could decrease the amount of earnings and assets available for distribution to
holders of common stock.
 
    (B) COMMON STOCK
 
    The Company amended and restated its Articles of Incorporation to restate
the common stock authorized, issued and outstanding from no par value to a $0.01
par value per common share. All share amounts have been restated to reflect this
amendment.
 
    (C) STOCK OPTION PLANS
 
    The Company adopted a 1997 Stock Option Plan and a 1997 Director Stock
Option Plan in February 1997 (the Plans). These Plans provide for the granting
of a maximum of 400,000 options to purchase shares of common stock to selected
employees, consultants, affiliates, and non-employee directors of the Company.
 
    In addition, effective upon completion of a public offering of common stock,
the vesting of all unvested options granted under the Employee Incentive Stock
Option Plan (Note 8) would be automatically accelerated and such options would
become fully vested and presently exercisable at such time.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Article XII of the Registrant's Amended and Restated Articles of
Incorporation provides the following:
 
   "A director of the Corporation shall not be liable to the Corporation or its
   shareholders for monetary damages for an act or omission in the director's
   capacity as a director, except that this Article shall not authorize the
   elimination or limitation of the liability of a director to the extent the
   director is found liable for:
 
            (1) a breach of the director's duty of loyalty to the Corporation or
       its shareholders;
 
            (2) an act or omission not in good faith that constitutes a breach
       of duty of the director to the Corporation or an act or omission that
       involves intentional misconduct or a knowing violation of the law;
 
            (3) a transaction from which the director received an improper
       benefit, whether or not the benefit resulted from an action taken within
       the scope of the director's office;
 
            (4) an act or omission for which the liability of a director is
       expressly provided by an applicable statute."
 
    Article XI of the Registrant's Amended and Restated Articles of
Incorporation provides the following:
 
   "The directors and officers of the Corporation shall be indemnified by the
   Corporation in a manner and to the maximum extent permitted by applicable
   state or federal law as in effect from time to time."
 
    Section 7.06 of the Registrant's Amended and Restated Bylaws provides the
following:
 
   "The Corporation shall have the authority to and shall indemnify and advance
   expenses to the Directors, officers, employees, and agents of the Corporation
   or any other persons serving at the request of the Corporation in such
   capacities in a manner and to the maximum extent permitted by applicable
   state or federal law. The Corporation may purchase and maintain liability
   insurance or
 
                                      II-1
<PAGE>
   make other arrangements for such obligations to the extent permitted by the
   Texas Business Corporation Act."
 
    The Texas Business Corporation Act permits, and in some cases requires,
corporations to indemnify officers, directors, agents and employees who are or
have been a party to or are threatened to be made a party to litigation against
judgments, penalties (including excise and similar taxes), fines, settlements
and reasonable expenses under certain circumstances.
 
    The Underwriting Agreement (Exhibit 1.1 hereto) provides for indemnification
by the Underwriters of the Company and its officers and directors, and by the
Company of the Underwriters, for certain liabilities arising under the
Securities Act or otherwise.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    The following sets forth information as of February 28, 1997, regarding all
sales of unregistered securities of the Registrant during the past three years.
All such shares were issued in reliance upon an exemption from registration
under the Securities Act by reason of Section 4(2) or 3(b) of the Securities Act
and/or the rules and regulations promulgated thereunder. In connection with each
of these transactions, the shares were sold to a very limited number of persons,
such persons were provided access to all relevant information regarding the
Registrant or represented to the Registrant that they were "sophisticated"
investors, and such persons represented to the Registrant that the shares were
purchased for investment purposes only and with no view toward distribution.
 
    The number of shares set forth herein and the prices paid per share have
been adjusted to reflect a 200-for-1 stock split of the Registrant's Common
Stock, par value $.01 per share.
 
    In June 1996, Kelly Dean, an employee of the Company, purchased 2,808 shares
of Common Stock for $3.56 per share for an aggregate purchase price of
approximately $10,000.
 
    In November 1996, Keith Johnson, Vice President--Marketing of the Company,
purchased 2,808 shares of Common Stock for $3.56 per share for an aggregate
purchase price of approximately $10,000.

ITEM 17. UNDERTAKINGS
 
    (a) The undersigned registrant (the "Registrant") hereby undertakes to
provide to the Underwriters, at the closing specified in the Underwriting
Agreement, certificates in such denominations and registered in such names as
required by the Underwriters to permit prompt delivery to each purchaser.
 
    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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 Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than 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, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its 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 Securities Act and will be governed by the final
adjudication of such issue.
 
    (c) The Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities 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 Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    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.

state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading; and at the time
the Registration Statement became or becomes, as the case may be, effective and

reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from

otherwise), earnings, operations, business or business prospects of the Company.

              (s)  Except as otherwise set forth in the Registration 
Statement and the Prospectus, each officer and director of the Company, and 
each shareholder that holds restricted securities has agreed in writing that 
such person will not, except as described below, for a period of 365 days 
from the date of the final Prospectus (the "Lock-Up Period"), sell, offer to 
sell, solicit an offer to buy, contract to sell, loan, pledge, grant any 
option to purchase, or otherwise transfer or dispose of (collectively, a 
"Disposition"), any shares of Common Stock, or any securities convertible 
into or exercisable or exchangeable for Common Stock (collectively, 
"Securities"), now owned or hereafter acquired by such person or with respect 
to which such person has or hereafter acquires the power of disposition 
otherwise than (i) on exercise (on a cash or cashless basis, whether in a 
traditional cashless exercise or in a "brokers" cashless exercise), of Common 
Stock options or warrants outstanding, it being understood, however, that the 
shares of Common Stock received (net of shares sold by or on behalf of such 
person in a "brokers" cashless exercise or shares delivered to the Company in 
a traditional cashless exercise thereof) by such person upon exercise thereof 
shall be subject to the terms of the Lock-Up Agreement (as defined below), 
(ii) on the transfer of shares of Common Stock or Securities during such 
person's lifetime by BONA FIDE gift or upon death by will or intestacy, 
provided that any transferee agrees to be bound by the Lock-Up Agreement, and 
(iii) on the transfer or other disposition of shares of Common Stock or 
Securities as a distribution to limited partners or shareholders of such 
person, provided that the distributees thereof agree to be bound by the terms 
of the Lock-Up Agreement.  The foregoing restriction has been expressly 
agreed to preclude the holder of the Securities from engaging in any hedging, 
pledge or other transaction which is designed to or may reasonably be 
expected to lead to or result in a Disposition of Securities during the 
Lock-up Period, even if such Securities would be disposed of by someone other 
than such shareholder.  Such prohibited hedging, pledge or other transactions 
would include, without limitation, any short sale (whether or not against the 
box) any pledge of shares covering an obligation that matures, or could 
reasonably mature during the Lock-Up Period, or any purchase, sale or grant 
of any right (including, without limitation, any put or call option) with 
respect to any Securities or with respect to any security (other than a 
broad-based market basket or index) that includes, relates to or derives any 
significant part of its value from Securities.  Furthermore, such person has 
also agreed and consented to the entry of stop transfer instructions with the 
Company's transfer agent against the transfer of the Securities held by such 
person except in compliance with this restriction.  The Company has provided 
to counsel for the Underwriters a complete and accurate list of all 
securityholders of the Company as of February 28, 1997 and the number and 
type of securities held by each securityholder.  The Company has provided to 
counsel for the Underwriters true, accurate and complete copies of all of the 
agreements pursuant to which its officers, directors and shareholders have 
agreed to such or similar restrictions (the "Lock-up Agreements") presently 
in effect or effected hereby.  The Company hereby represents and warrants 
that it will not release any of its officers, directors or other shareholders 
from any Lock-up Agreements currently existing or hereafter effected without 
the prior written consent of Cruttenden Roth Incorporated.

executed in accordance with management's general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets, (iii) access to assets is permitted only in

              (u)  There are no outstanding loans, advances (except normal
advances for business expenses in the ordinary course of business) or guarantees
of indebtedness by the Company to or for the benefit of any of the officers or

              (v)  Other than Cruttenden Roth Incorporated, on behalf of the

or similar payment in connection with the transactions contemplated by this
Agreement.
         
    3.   PURCHASE, SALE AND DELIVERY OF SHARES.  On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and each Underwriter agrees, severally and not jointly, to
purchase from the Company, at a purchase price of $_____ per share, the
respective number of Firm Shares which is set forth opposite the name of such
Underwriter in Schedule A hereto (subject to adjustment as provided in Section
10).

         Delivery of definitive certificates for the Firm Shares to be
purchased by the Underwriters pursuant to this Section 3 shall be made against
payment of the purchase price therefor by the several Underwriters by certified
or official bank check or checks drawn in next-day funds, payable to the order
of the Company (and the Company agrees not to deposit any such check in the bank
on which it is drawn, and not to take any other action with the purpose or
effect of receiving immediately available funds, until the business day
following the date of delivery to the Company and, in the event of any breach of
the foregoing, the Company shall reimburse the Underwriters for the interest
lost and any other expenses borne by the Underwriters by reason of such breach),
at the offices of Brobeck, Phleger & Harrison LLP, 301 Congress Avenue, Suite
1200, Austin, Texas (or at such other place as may be agreed upon between the
Representative and the Company, at 7:00 A.M. Pacific daylight savings time, (a)
on the third (3rd) full business day following the first day that Shares are
traded, (b) if this Agreement is executed and delivered after 1:30 P.M. Pacific
daylight savings time, the fourth (4th) full business day following the day that
this Agreement is executed and delivered or (c) at such other time and date not
later than seven (7) full business days following the first day that Shares are
traded as the Representative and the Company may determine (or at such time and
date to which payment and delivery shall have been postponed pursuant to Section
10 hereof), such time and date of payment and delivery being herein called the
"Closing Date"; PROVIDED, HOWEVER, that if the Company has not made available to
the Representative copies


                                         -10-

<PAGE>


of the Prospectus within the time provided in Section 4(d) hereof, the
Representative may, in its sole discretion, postpone the Closing Date until no
later than two (2) full business days following delivery of copies of the
Prospectus to the Representative.  The certificates for the Firm Shares to be so
delivered will be made available to you at such office or such other location
including, without limitation, in New York City, as you may reasonably request
for checking at least one (1) full business day prior to the Closing Date and
will be in such names and denominations as you may request, such request to be
made at least two (2) full business days prior to the Closing Date.  If the
Representative so elects, delivery of the Firm Shares may be made by credit
through full fast transfer to the accounts at The Depository Trust Company
designated by the Representative.

         It is understood that you, individually, and not as the Representative
of the several Underwriters, may (but shall not be obligated to) make payment of
the purchase price on behalf of any Underwriter or Underwriters whose check or
checks shall not have been received by you prior to the Closing Date for the
Firm Shares to be purchased by such Underwriter or Underwriters.  Any such
payment by you shall not relieve any such Underwriter or Underwriters of any of
its or their obligations hereunder.

         After the Registration Statement becomes effective, the several
Underwriters intend to make a public offering (as such term is described in
Section 11 hereof) of the Firm Shares at a public offering price of $_____ per
share.  After the public offering, the several Underwriters may, in their
discretion, vary the public offering price.

         The information set forth on the front cover page (insofar as such
information relates to the Underwriters) concerning stabilization,
over-allotment and passive market making by the Underwriters, and under the
first, third, eighth and last paragraphs under the caption "Underwriting" in any
Preliminary Prospectus and in the Prospectus constitutes the only information
furnished by the Underwriters to the Company for inclusion in any Preliminary
Prospectus, the Prospectus or the Registration Statement, and you, on behalf of
the respective Underwriters, represent and warrant to the Company that the
statements made therein do not include any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

    4.   FURTHER AGREEMENTS OF THE COMPANY.  The Company agrees with the
several Underwriters that:

              (a)  The Company will use its best efforts to cause the
Registration Statement and any amendment thereof, if not effective at the time
and date that this Agreement is executed and delivered by the parties hereto, to
become effective as promptly as possible; the Company will use its best efforts
to cause any abbreviated registration statement pursuant to Rule 462(b) of the
Rules and Regulations as may be required subsequent to the date the Registration
Statement is declared effective to become effective as promptly as possible; the
Company will notify you, promptly after it shall receive notice thereof, of the
time when the Registration Statement, any subsequent amendment to the
Registration Statement or any abbreviated registration statement has become


                                         -11-

<PAGE>


effective or any supplement to the Prospectus has been filed; if the Company
omitted information from the Registration Statement at the time it was
originally declared effective in reliance upon Rule 430A(a) of the Rules and
Regulations, the Company will provide evidence satisfactory to you that the
Prospectus contains such information and has been filed, within the time period
prescribed, with the Commission pursuant to subparagraph (1) or (4) of Rule
424(b) of the Rules and Regulations or as part of a post-effective amendment to
such Registration Statement as originally declared effective which is declared
effective by the Commission; if the Company files a term sheet pursuant to Rule
434 of the Rules and Regulations, the Company will provide evidence satisfactory
to you that the Prospectus and term sheet meeting the requirements of Rule
434(b) or (c), as applicable, of the Rules and Regulations have been filed,
within the time period prescribed, with the Commission pursuant to subparagraph
(7) of Rule 424(b) of the Rules and Regulations; if for any reason the filing of
the final form of Prospectus is required under Rule 424(b)(3) of the Rules and
Regulations, it will provide evidence satisfactory to you that the Prospectus
contains such information and has been filed with the Commission within the time
period prescribed; it will notify you promptly of any request by the Commission
for the amending or supplementing of the Registration Statement or the
Prospectus or for additional information; promptly upon your request, it will
prepare and file with the Commission any amendments or supplements to the
Registration Statement or Prospectus which, in the opinion of counsel for the
several Underwriters ("Underwriters' Counsel"), may be necessary or advisable in
connection with the distribution of the Shares by the Underwriters; it will
promptly prepare and file with the Commission, and promptly notify you of the
filing of, any amendments or supplements to the Registration Statement or
Prospectus which may be necessary to correct any statements or omissions, if, at
any time when a prospectus relating to the Shares is required to be delivered
under the Act, any event shall have occurred as a result of which the Prospectus
or any other prospectus relating to the Shares as then in effect would include
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; in case any Underwriter is required
to deliver a prospectus nine (9) months or more after the effective date of the
Registration Statement in connection with the sale of the Shares, it will
prepare promptly upon request, but at the expense of such Underwriter, such
amendment or amendments to the Registration Statement and such prospectus or
prospectuses as may be necessary to permit compliance with the requirements of
Section 10(a)(3) of the Act; and it will file no amendment or supplement to the
Registration Statement or Prospectus which shall not previously have been
submitted to you a reasonable time prior to the proposed filing thereof or to
which you shall reasonably object in writing, subject, however, to compliance
with the Act and the Rules and Regulations and the provisions of this Agreement.

              (b)  The Company will advise you, promptly after it shall receive
notice or obtain knowledge, of the issuance of any stop order by the Commission
suspending the effectiveness of the Registration Statement or of the initiation
or threat of any proceeding for that purpose; and it will promptly use its best
efforts to prevent the issuance of any stop order or to obtain its withdrawal at
the earliest possible moment if such stop order should be issued.

              (c)  The Company will use its best efforts (including by
providing full cooperation with your counsel, whose services in this matter are
required and which you and the


                                         -12-

<PAGE>


Company will seek to expedite) to qualify the Shares for offering and sale under
the securities laws of such jurisdictions as you may designate and to continue
such qualifications in effect for so long as may be required for purposes of the
distribution of the Shares, except that the Company shall not be required in
connection therewith or as a condition thereof to qualify as a foreign
corporation or to execute a general consent to service of process in any
jurisdiction in which it is not otherwise required to be so qualified or to so
execute a general consent to service of process.  In each jurisdiction in which
the Shares shall have been qualified as above provided, the Company will make
and file such statements and reports in each year as are or may be required by
the laws of such jurisdiction for such purpose.

              (d)  The Company will furnish to you, as soon as available, and,
in the case of the Prospectus and any term sheet or abbreviated term sheet under
Rule 434, in no event later than the first full business day following the first
day that Shares are traded, copies of the Registration Statement (two of which
will be signed and which will include all exhibits), each Preliminary
Prospectus, the Prospectus and any amendments or supplements to such documents,
including any prospectus prepared to permit compliance with Section 10(a)(3) of
the Act, all in such quantities as you may from time to time reasonably request.
Notwithstanding the foregoing, if Cruttenden Roth Incorporated, on behalf of the
several Underwriters, shall agree to the utilization of Rule 434 of the Rules
and Regulations, the Company shall provide to you copies of a Preliminary
Prospectus updated in all respects through the date specified by you in such
quantities as you may from time to time reasonably request.

              (e)  The Company will make generally available to its 
securityholders as soon as practicable, but in any event not later than the 
forty-fifth (45th) day following the end of the fiscal quarter first 
occurring after the first anniversary of the effective date of the 
Registration Statement, an earnings statement (which will be in reasonable 
detail but need not be audited) complying with the provisions of Section 
11(a) of the Act and covering a twelve (12) month period beginning after the 
effective date of the Registration Statement.

              (f)  During a period of five (5) years after the date hereof, the
Company will furnish to its shareholders as soon as practicable after the end of
each respective period, annual reports (including financial statements audited
by independent certified public accountants) and, upon request by a shareholder,
unaudited quarterly reports of operations for each of the first three quarters
of the fiscal year, and will furnish to you and the other several Underwriters
hereunder, upon request (i) concurrently with furnishing such reports to its
shareholders, statements of operations of the Company for each of the first
three (3) quarters in the form furnished to the Company's shareholders, (ii)
concurrently with furnishing to its shareholders, a balance sheet of the Company
as of the end of such fiscal year, together with statements of operations, of
shareholders' equity, and of cash flows of the Company for such fiscal year,
accompanied by a copy of the certificate or report thereon of independent
certified public accountants, (iii) as soon as they are available, copies of all
reports (financial or other) mailed to shareholders, (iv) as soon as they are
available, copies of all reports and financial statements furnished to or filed
with the Commission, any securities exchange or the NASD, (v) every material
press release and every material news item or article in respect of the Company
or


                                         -13-

<PAGE>


its affairs which was generally released to shareholders or prepared by the
Company, and (vi) any additional information of a public nature concerning the
Company, or its business which you may reasonably request.  During such five (5)
year period, if the Company shall have active subsidiaries, the foregoing
financial statements shall be on a consolidated basis to the extent that the
accounts of the Company and such subsidiaries are consolidated, and shall be
accompanied by similar financial statements for any significant subsidiary which
is not so consolidated.

              (g)  The Company will apply the net proceeds from the sale of the
Shares being sold by it in the manner set forth under the caption "Use of
Proceeds" in the Prospectus.

              (h)  The Company will maintain a transfer agent and, if necessary
under the jurisdiction of incorporation of the Company, a registrar (which may
be the same entity as the transfer agent) for its Common Stock.

              (i)  If the transactions contemplated hereby are not consummated
by reason of any failure, refusal or inability on the part of the Company to
perform any agreement on its part to be performed hereunder or to fulfill any
condition of the Underwriters' obligations hereunder, or if the Company shall
terminate this Agreement pursuant to Section 11(a) hereof, or if the
Underwriters shall terminate this Agreement pursuant to Section 11(a) or 11(b),
then the provisions of Section 11 of that certain letter agreement dated October
17, 1996 between you and the Company (the "Letter Agreement") shall govern
payment and reimbursement obligations of the parties notwithstanding that the
Letter Agreement shall have ceased to be of full force or effect for any other
purpose.

              (j)  If at any time during the ninety (90) day period after the
Registration Statement becomes effective, any rumor, publication or event
relating to or affecting the Company shall occur as a result of which in your
opinion the market price of the Common Stock has been or is likely to be
materially affected (regardless of whether such rumor, publication or event
necessitates a supplement to or amendment of the Prospectus), the Company will,
after written notice from you advising the Company to the effect set forth
above, forthwith prepare, consult with you concerning the substance of and
disseminate a press release or other public statement, reasonably satisfactory
to you, responding to or commenting on such rumor, publication or event.

              (k)  During the Lock-up Period, the Company will not, without the
prior written consent of Cruttenden Roth Incorporated, effect the Disposition
of, directly or indirectly, any Securities other than the sale of the Firm
Shares and the Option Shares hereunder and the Company's issuance of options or
Common Stock under the Company's presently authorized stock option and stock
purchase plans described in the Registration Statement and the Prospectus.  

              (l)  The terms of paragraph 9 of the Letter Agreement are hereby
incorporated by reference and made obligations of the Company and Cruttenden
Roth Incorporated as part of this Agreement notwithstanding that the Letter
Agreement shall have ceased to be of full force or effect for any other purpose.

              (m)  The Company shall reimburse and pay to Cruttenden Roth
Incorporated a nonaccountable expense allowance equal to two percent (2.0%) of
the total Price to Public shown on the front cover of the Prospectus, including,
if exercised, with respect to the over-allotment option.  Cruttenden Roth
Incorporated acknowledges that $30,000 of the amount payable pursuant to this
paragraph has already been paid.

    5.   EXPENSES.

              (a)  The Company agrees with each Underwriter that:

                        (i)  The Company will pay and bear all costs and
expenses in connection with the preparation, printing and filing of the
Registration Statement (including financial statements, schedules and exhibits),
Preliminary Prospectuses and the Prospectus and any amendments or supplements
thereto; the printing of this Agreement, the Agreement Among Underwriters, the
Selected Dealer Agreement, the Preliminary Blue Sky Survey and any Supplemental
Blue Sky Survey, the Underwriters' Questionnaire and Power of Attorney, and any
instruments related to any of the foregoing; the issuance and delivery of the
Shares hereunder to the several Underwriters, including transfer taxes, if any,
the cost of all certificates representing the Shares and transfer agents' and
registrars' fees; the fees and disbursements of counsel for the Company; all
fees and other charges of the Company's independent certified public
accountants; the cost of furnishing to the several Underwriters copies of the
Registration Statement (including appropriate exhibits), Preliminary Prospectus
and the Prospectus, and any amendments or supplements to any of the foregoing;
NASD filing fees and the cost of qualifying the Shares under the laws of such
jurisdictions as you may designate (including filing fees and fees and
disbursements of Underwriters' Counsel in connection with such NASD filings and
Blue Sky qualifications); and all other expenses directly incurred by the
Company in connection with the performance of its obligations hereunder.  The
provisions of this Section 5(a)(i) are intended to relieve the Underwriters from
the payment of the expenses and costs which the Company hereby agrees to pay.

                        (ii) In addition to its other obligations under Section
8(a) hereof, the Company agrees that, as an interim measure during the pendency
of any claim, action, investigation, inquiry or other proceeding described in
Section 8(a) hereof, it will reimburse the Underwriters on a monthly basis for
all reasonable legal or other expenses incurred in connection with investigating
or defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the Company's obligation to reimburse the Underwriters for
such expenses and the possibility that such payments might later be held to have
been improper by a court of competent jurisdiction.  To the extent that any such
interim reimbursement payment is so held to have been improper, the Underwriters
shall promptly return such payment to the Company together with interest,
compounded daily, determined on the basis of the prime rate (or other commercial
lending rate for borrowers of the highest credit standing) listed from time to
time in THE WALL STREET JOURNAL which represents the base rate on corporate
loans posted by a substantial majority of the nation's thirty (30) largest banks
(the "Prime Rate").  Any such interim reimbursement payments which are not made
to the Underwriters within thirty (30) days of a request for reimbursement shall
bear interest at the Prime Rate from the date of such request.

              (b)  In addition to their other obligations under Section 8(b)
hereof, the Underwriters severally and not jointly agree that, as an interim
measure during the pendency of any claim, action, investigation, inquiry or
other proceeding described in Section 8(b) hereof, they will


                                         -16-

<PAGE>


reimburse the Company on a monthly basis for all reasonable legal or other
expenses incurred in connection with investigating or defending any such claim,
action, investigation, inquiry or other proceeding, notwithstanding the absence
of a judicial determination as to the propriety and enforceability of the
Underwriters' obligation to reimburse the Company for such expenses and the
possibility that such payments might later be held to have been improper by a
court of competent jurisdiction.  To the extent that any such interim
reimbursement payment is so held to have been improper, the Company shall
promptly return such payment to the Underwriters together with interest,
compounded daily, determined on the basis of the Prime Rate.  Any such interim
reimbursement payments which are not made to the Company within thirty (30) days
of a request for reimbursement shall bear interest at the Prime Rate from the
date of such request.

              (c)  It is agreed that any controversy arising out of the
operation of the interim reimbursement arrangements set forth in Sections
5(a)(ii) and 5(b) hereof, including the amounts of any requested reimbursement
payments, the method of determining such amounts and the basis on which such
amounts shall be apportioned among the reimbursing parties, shall be settled by
arbitration conducted under the provisions of the Constitution and Rules of the
Board of Governors of the New York Stock Exchange, Inc. or pursuant to the Code
of Arbitration Procedure of the NASD.  Any such arbitration must be commenced by
service of a written demand for arbitration or a written notice of intention to
arbitrate, therein electing the arbitration tribunal.  In the event the party
demanding arbitration does not make such designation of an arbitration tribunal
in such demand or notice, then the party responding to said demand or notice is
authorized to do so.  Any such arbitration will be limited to the operation of
the interim reimbursement provisions contained in Sections 5(a)(ii) and 5(b)
hereof and will not resolve the ultimate propriety or enforceability of the
obligation to indemnify for expenses which is created by the provisions of
Sections 8(a) and 8(b) hereof or the obligation to contribute to expenses which
is created by the provisions of Section 8(d) hereof.

    6.   CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the
several Underwriters to purchase and pay for the Shares as provided herein shall
be subject to the accuracy, as of the date hereof and the Closing Date and any
later date on which Option Shares are to be purchased, as the case may be, of
the representations and warranties of the Company herein, to the performance by
the Company of its obligations hereunder and to the following additional
conditions:

              (a)  The Registration Statement shall have become effective not
later than 2:00 P.M., Pacific daylight savings time, on the date following the
date of this Agreement, or such later date and time as shall be consented to in
writing by you; and no stop order suspending the effectiveness thereof shall
have been issued and no proceedings for that purpose shall have been initiated
or, to the knowledge of the Company or any Underwriter, threatened by the
Commission, and any request of the Commission for additional information (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to the satisfaction of Underwriters' Counsel.


                                         -17-

<PAGE>


              (b)  All corporate proceedings and other legal matters in
connection with this Agreement, the form of Registration Statement and the
Prospectus, and the registration, authorization, issue, sale and delivery of the
Shares, shall have been reasonably satisfactory to Underwriters' Counsel, and
such counsel shall have been furnished with such papers and information as they
may reasonably have requested to enable them to pass upon the matters referred
to in this Section.

              (c)  Subsequent to the execution and delivery of this Agreement
and prior to the Closing Date, or any later date on which Option Shares are to
be purchased, as the case may be, there shall not have been any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company from that set forth in the Registration Statement or
Prospectus, which, in your sole judgment, is material and adverse and that makes
it, in your sole judgment, impracticable or inadvisable to proceed with the
public offering of the Shares as contemplated by the Prospectus. 

              (d)  You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, the
following opinion of counsel for the Company dated the Closing Date or such
later date on which Option Shares are to be purchased addressed to the
Underwriters and with reproduced copies or signed counterparts thereof for each
of the Underwriters, to the effect that:

                        (i)       The Company and its subsidiaries have been
         duly incorporated and are validly existing as corporations in good
         standing under the laws of the jurisdiction of their incorporation;

                        (ii)      The Company has the corporate power and
         authority to own, lease and operate its properties and to conduct its

         as a foreign corporation and is in good standing in each jurisdiction,
         if any, in which the ownership or leasing of its properties or the
         conduct of its business requires such qualification, except where the
         failure to be so qualified or be in good standing would not have a
         material adverse effect on the condition (financial or otherwise),
         earnings, operations or business of the Company.  To such counsel's
         knowledge, the Company does not own or control, directly or
         indirectly, any corporation, association or other entity other than
         IWL Communications, Ltd., a corporation organized under the laws of
         Russia, IWL Baltija Communications (Latvia) SIA, a corporation
         organized under the laws of Latvia, each of which is a wholly-owned
         subsidiary of the Company, and Kenwood Systems Group, Inc., a
         California corporation of which the Company owns 50% of the
         outstanding Common Stock;

         the caption "Capitalization" as of

         stock of the Company have been duly and validly issued and are fully
         paid and nonassessable, and will not have been issued in violation of
         or subject to any preemptive right, co-sale right, registration right,
         right of first refusal or other similar right;

                        (v)       The Firm Shares or the Option Shares, as the
         case may be, to be issued by the Company pursuant to the terms of this
         Agreement have been duly authorized and, upon issuance and delivery
         against payment therefor in accordance with the terms hereof, will be
         duly and validly issued and fully paid and nonassessable and will not
         have been issued in violation of or subject to any preemptive right,
         co-sale right, registration right, right of first refusal or other
         similar right contained in the Company's charter or bylaws or in any
         other agreement or contract to which the Company is a party; and the

                        (vi)      The Company has the corporate power and
         authority to enter into this Agreement and to issue, sell and deliver
         to the Underwriters the Shares to be issued and sold by it hereunder;

                        (vii)     This Agreement has been duly authorized by
         all necessary corporate action on the part of the Company and has been
         duly executed and delivered by the Company and, assuming due
         authorization, execution and delivery by you, is a valid and binding
         agreement of the Company, enforceable in accordance with its terms,
         except insofar as indemnification provisions may be limited by
         applicable law and except as enforceability may be limited by
         bankruptcy, insolvency, reorganization, moratorium or similar laws
         relating to or affecting creditors' rights generally or by general
         equitable principles;

                        (viii)    The Registration Statement has become
         effective under the Act and, to such counsel's knowledge, no stop
         order suspending the effectiveness of the Registration Statement has
         been issued and no proceedings for that purpose have been instituted
         or are pending or threatened under the Act;

                        
                        (ix)      The Registration Statement and the
         Prospectus, and each amendment or supplement thereto (other than the
         financial statements (including supporting schedules), financial data
         derived therefrom and other financial and statistical information
         included therein as to which such counsel need express no opinion), as
         of the effective date of the Registration Statement, complied as to
         form in all material respects with the requirements of the Act and the
         applicable Rules and Regulations;

<PAGE>


                        (x)       The information in the Prospectus under the
         caption "Description of Capital Stock," to the extent that it
         constitutes matters of law or legal conclusions, has been reviewed by
         such counsel and is a fair summary of such matters and conclusions;


                        (xi)      The description in the Registration Statement
              and the Prospectus of the charter and bylaws of the Company and
              of statutes are accurate and fairly present the information
              required to be presented by the Act and the applicable Rules and
              Regulations;

                        (xii)     To such counsel's knowledge, there are no
         agreements, contracts, leases or documents to which the Company is a
         party of a character required to be described or referred to in the
         Registration Statement or Prospectus or to be filed as an exhibit to
         the Registration Statement which are not described or referred to
         therein or filed as required;

                        (xiii)    The performance of this Agreement and the
         consummation of the transactions herein contemplated (other than
         performance of the Company's indemnification obligations hereunder,
         concerning which no opinion need be expressed) will not (a) result in
         any violation of the charter or bylaws of the Company or (b) result in
         a material breach or violation of any of the terms and provisions of,
         or constitute a default under, any material bond, debenture, note or
         other evidence of indebtedness, or any material lease, contract,
         indenture, mortgage, deed of trust, loan agreement, joint venture or
         other agreement or instrument to which the Company is a party or by
         which its properties are bound, or any applicable statute, rule or
         regulation or any order, writ or decree of any court, government or
         governmental agency or body having jurisdiction over the Company or
         any of its properties or operations; provided, however, that such
         counsel need not express any opinion or belief with respect to state
         securities or Blue Sky laws;

                        (xiv)     No consent, approval, authorization or order
         of or qualification with any court, government or governmental agency
         or body having jurisdiction over the Company or any of its properties
         or operations is necessary in connection with the consummation by the
         Company of the transactions herein contemplated, except such as have
         been obtained under the Act or such as may be required under state or
         other securities or Blue Sky laws in connection with the purchase and
         the distribution of the Shares by the Underwriters;

                        (xv)      To such counsel's best knowledge, there are
         no legal or governmental proceedings pending or threatened against the
         Company of a character required to be disclosed in the Registration
         Statement or the Prospectus by the Act or the Rules and Regulations,
         other than those described therein;

                        (xvi)     The Company is not in violation of its
         respective charter or bylaws.

                        (xvii)    To such counsel's best knowledge, except as 
         set forth in the Registration Statement and Prospectus, no holders of
         Common Stock or other securities of the Company have registration
         rights with respect to securities of the Company and, except as set
         forth in the Registration Statement and Prospectus, all holders of
         securities of the Company having rights to registration of such shares
         of Common Stock or other securities, because of the filing of the
         Registration Statement by the Company have, with respect to the
         offering contemplated thereby, waived such rights or such rights have
         expired by reason of lapse of time following notification of the
         Company's intent to file the Registration Statement; and

                        (xviii)   Except as set forth in the Registration
         Statement and the Prospectus, such counsel has no knowledge of any
         actual or threatened action, suit, claim or proceeding relating to
         patents, patent rights or licenses, trademarks or trademark rights,
         copyrights, collaborative research, licenses or royalty arrangements
         or agreements or trade secrets, know-how or proprietary techniques or
         technology, including, processes and substances, owned by or affecting
         the business operations of the company which are pending or threatened
         against the Company and which action, suit, claim or proceeding would,
         with respect to any of the foregoing, have a material adverse effect
         on the condition (financial or other), earnings, operations, business
         or business prospects of the Company.

              In addition, such counsel shall state that such counsel has acted
as outside corporate legal counsel to the Company and participated in
conferences with officials and other representatives of the Company, the
Representative, Underwriters' Counsel and the independent certified public
accountants of the Company, at which such conferences the contents of the
Registration Statement and Prospectus and related matters were discussed, and
although they have not verified the accuracy or completeness of the statements
contained in the Registration Statement or the Prospectus, nothing has come to
the attention of such counsel which leads such counsel to believe that, at the
time the Registration Statement became effective and at all times subsequent
thereto up to and on the Closing Date and on any later date on which Option
Shares are to be purchased, the Registration Statement and any amendment or
supplement thereto (other than the financial statements including supporting
schedules, other financial  information derived therefrom and other financial
and statistical information included therein, as to which such counsel need
express no opinion) contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading, or at the Closing Date or any later date on
which the Option Shares are to be purchased, as the case may be, the
Registration Statement, the Prospectus and any amendment or supplement thereto
(except as aforesaid) contained any untrue statement of a material fact or
omitted to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. 

              Counsel rendering the foregoing opinion may rely as to questions
of law not involving the laws of the United States or the State of Texas upon
opinions of local counsel, and as to questions of fact upon representations or
certificates of officers of the Company, and of government


                                         -22-

<PAGE>


officials, in which case their opinion is to state that they are so relying and
that they have no knowledge of any material misstatement or inaccuracy in any
such opinion, representation or certificate.  Copies of any opinion,
representation or certificate so relied upon shall be delivered to you, as
Representative of the Underwriters, and to Underwriters' Counsel.

              (e)  You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, an opinion
of Brobeck, Phleger & Harrison LLP, in form and substance reasonably
satisfactory to you, with respect to the sufficiency of all such corporate
proceedings and other legal matters relating to this Agreement and the
transactions contemplated hereby as you may reasonably require, and the Company
shall have furnished to such counsel such documents as they may have requested
for the purpose of enabling them to pass upon such matters.

              (f)  You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, an opinion
of Swiddler & Berlin dated the Closing Date or such later date on which Option
Shares are to be purchased and addressed to the Underwriters and with reproduced
copies or signed counterparts thereof for each of the Underwriters, that the
information in the Registration Statement and the Prospectus under the captions
"Risk Factors--Government Regulation" and "Business--Government Regulation," to
the extent that they constitute matters of law or legal conclusions, have been
reviewed by such counsel and are a fair and accurate summary of such matters.

              In addition, such counsel shall state that such counsel has
represented the Company in regulatory-related matters, and has participated in
conferences with officials and other representatives of the Company, the
Representative, Underwriters' Counsel and the independent certified public
accountants of the Company, at which such conferences the contents of the
relevant sections ("Relevant Sections") of the Registration Statement and
Prospectus and related matters were discussed, and although they have not
verified the accuracy or completeness of the statements contained in the
Relevant Sections of the Registration Statement or the Prospectus, nothing has
come to the attention of such counsel which leads such counsel to believe that,
at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the Closing Date and on any later date on which
Option Shares are to be purchased, the Relevant Sections of the Registration
Statement and any amendment or supplement thereto (other than the financial
statements including supporting schedules and other financial and statistical
information derived therefrom, as to which such counsel need express no comment)
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, or at the Closing Date or any later date on which the Option
Shares are to be purchased, as the case may be, the Relevant Sections of the
Registration Statement, the Prospectus and any amendment or supplement thereto
(except as aforesaid) contained any untrue statement of a material fact or
omitted to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

              (g)  You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a letter
from KPMG Peat Marwick LLP, Independent Auditors ("Peat Marwick"),  addressed to
the Underwriters, dated the Closing Date or such later date on which Option
Shares are to be purchased, as the case may be (in each case, the "Bring Down
Letter"), confirming that they are independent certified public accountants with
respect to the Company within the meaning of the Act and the applicable
published Rules and Regulations and based upon the procedures described in a
letter delivered to you concurrently with the execution of this Agreement
(herein called the "Original Letter"), but carried out to a date not more than
five (5) business days prior to the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, (i) confirming, to the
extent true, that the statements and conclusions set forth in the Original
Letter are accurate as of the Closing Date or such later date on which Option
Shares are to be purchased, as the case may be, and (ii) setting forth any
revisions and additions to the statements and conclusions set forth in the
Original Letter that are necessary to reflect any changes in the facts described
in the Original Letter since its date, or to reflect the availability of more
recent financial statements, data or information.  The Bring Down Letter shall
not disclose any change in the condition (financial or otherwise), earnings,
operations, business or business prospects of the Company from that set forth in
the Registration Statement or Prospectus, which, in your sole judgment, is
material and adverse and that makes it, in your sole judgment, impracticable or
inadvisable to proceed with the public offering of the Shares as contemplated by
the Prospectus.  The Original Letter from Peat Marwick shall be addressed to or
for the use of the Underwriters in form and substance satisfactory to the
Underwriters and shall (i) represent, to the extent true, that they are
independent certified public accountants with respect to the Company within the
meaning of the Act and the applicable published Rules and Regulations, (ii) set
forth their opinion with respect to their examination of the balance sheet of
the Company as of June 30, 1996, 1995 and 1994 and March 31, 1997 and related
statements of operations, shareholders' equity and cash flows for the twelve
(12) months ended June 30, 1996, 1995 and 1994 and the nine (9) months ended
March 31, 1997, (iii) state that nothing came to their attention that caused
them to believe that the financial statements included in the Registration
Statement and Prospectus do not comply as to form in all material respects with
the applicable accounting requirements of Rule 11-02 of Regulation S-X and that
any adjustments thereto have not been properly applied to the historical amounts
in the compilation of such statements, and (iv) address other matters agreed
upon by Peat Marwick and you.  In addition, you shall have received from Peat
Marwick a letter addressed to the Company and made available to you for the use
of the Underwriters stating that their review of the Company's system of
internal accounting controls, to the extent they deemed necessary in
establishing the scope of their examination of the Company's financial
statements as of March 31, 1997, did not disclose any weaknesses in internal
controls that they considered to be material weaknesses.

              (h)  You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a
certificate of the Company, dated the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, signed by the Chief
Executive Officer and Chief Financial Officer of the Company, to the effect
that, and you shall be satisfied that:


                                         -24-

<PAGE>


                        (i)       The representations and warranties of the
         Company in this Agreement are true and correct, as if made on and as
         of the Closing Date or any later date on which Option Shares are to be
         purchased, as the case may be, and the Company has complied with all
         the agreements and satisfied all the conditions on its part to be
         performed or satisfied at or prior to the Closing Date or any later
         date on which Option Shares are to be purchased, as the case may be;

                        (ii)      No stop order suspending the effectiveness of
         the Registration Statement has been issued and no proceedings for that
         purpose have been instituted or are pending or threatened under the
         Act;

                        (iii)     When the Registration Statement became
         effective and at all times subsequent thereto up to the delivery of
         such certificate, the Registration Statement and the Prospectus, and
         any amendments or supplements thereto, contained all material
         information required to be included therein by the Act and the Rules
         and Regulations, and in all material respects conformed to the
         requirements of the Act and the Rules and Regulations, the
         Registration Statement, and any amendment or supplement thereto, did
         not and does not include any untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, the
         Prospectus, and any amendment or supplement thereto, did not and does
         not include any untrue statement of a material fact or omit to state a
         material fact necessary to make the statements therein, in light of
         the circumstances under which they were made, not misleading, and,
         since the effective date of the Registration Statement, there has
         occurred no event required to be set forth in an amended or
         supplemented Prospectus which has not been so set forth; and

                        (iv)      Subsequent to the respective dates as of
         which information is given in the Registration Statement and
         Prospectus, there has not been (a) any material adverse change in the
         condition (financial or otherwise), earnings, operations, business or
         business prospects of the Company, (b) any transaction that is
         material to the Company, except transactions entered into in the
         ordinary course of business, (c) any obligation, direct or contingent,
         that is material to the Company, incurred by the Company, except
         obligations incurred in the ordinary course of business, (d) any
         change in the capital stock or outstanding indebtedness of the Company
         that is material to the Company or is out of the ordinary course of
         business of the Company, (e) any dividend or distribution of any kind
         declared, paid or made on the capital stock of the Company, or (f) any
         loss or damage (whether or not insured) to the property of the Company
         which has been sustained or will have been sustained which has a
         material adverse effect on the condition (financial or otherwise),
         earnings, operations, business or business prospects of the Company.

              (i)  The Company shall have obtained and delivered to you an
agreement from each officer and director of the Company, each shareholder that
holds restricted securities and each entity that is a shareholder and is
affiliated with an officer or director of the Company in writing prior to the
date hereof that such person will not, except as described below, during the
Lock-up Period, effect the Disposition of any Securities now owned or hereafter
acquired by such person or with respect to which such person has or hereafter
acquires the power of disposition, otherwise than (i) on exercise (on a cash or
cashless basis, whether in a traditional cashless exercise or in a "brokers"
cashless exercise), of Common Stock options or warrants outstanding, it being
understood, however, that the shares of Common Stock received (net of shares
sold by or on behalf of such person in a "brokers" cashless exercise or shares
delivered to the Company in a traditional cashless exercise thereof) by such
person upon exercise thereof shall be subject to the terms of the Lock-Up
Agreement, (ii) on the transfer of shares of Common Stock or Securities during
such person's lifetime by BONA FIDE gift or upon death by will or intestacy,
provided that any transferee agrees to be bound by the Lock-Up Agreement, and
(iii) on the transfer or other disposition of shares of Common Stock or
Securities as a distribution to limited partners or shareholders of such person,
provided that the distributees thereof agree to be bound by the terms of the
Lock-Up Agreement.  The foregoing restriction shall have been expressly agreed
to preclude the holder of the Securities from engaging in any hedging, pledge or
other transaction which is designed to or may reasonably be expected to lead to
or result in a Disposition of Securities during the Lock-Up Period, even if such
Securities would be disposed of by someone other than the such holder.  Such
prohibited hedging, pledge or other transactions would include, without
limitation, any short sale (whether or not against the box), any pledge of
shares covering an obligation that matures or could reasonably mature during the
Lock-Up Period, or any purchase, sale or grant of any right (including, without
limitation, any put or call option) with respect to any Securities or with
respect to any security (other than a broad-based market basket or index) that
includes, relates to or derives any significant part of its value from
Securities. Furthermore, such person will have also agreed and consented to the
entry of stop transfer instructions with the Company's transfer agent against
the transfer of the Securities held by such person except in compliance with
this restriction. 
         
                   (j)  The Company shall have furnished you a warrant for the
purchase of up to 125,000 shares of Common Stock at an exercise price per share
equal to 120% of the offering price per share of the Shares, in the form
attached hereto as Exhibit A.
         
                   (k)  The Company shall have furnished to you such further
certificates and documents as you shall reasonably request (including
certificates of officers of the Company) as to the accuracy of the
representations and warranties of the Company herein, as to the performance by
the Company of its obligations hereunder and as to the other conditions
concurrent and precedent to the obligations of the Underwriters hereunder.

              All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel.  The Company will furnish you with such number of
conformed copies of such opinions, certificates, letters and documents as you
shall reasonably request.

    7.   OPTION SHARES.

              (a)  On the basis of the representations, warranties and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company hereby grants to the several Underwriters, for the purpose of
covering over-allotments in connection with the distribution and sale of the
Firm Shares only, a nontransferable option to purchase up to an aggregate of
187,500 Option Shares at the purchase price per share for the Firm Shares set
forth in Section 3 hereof.  Such option may be exercised by the Representative
on behalf of the several Underwriters on one (1) or more occasions in whole or
in part during the period of  forty-five (45) days after the date on which the
Firm Shares are initially offered to the public by giving written notice (the
"Option Notice") to the Company.  The number of Option Shares to be purchased by
each Underwriter upon the exercise of such option shall be the same proportion
of the total number of Option Shares to be purchased by the several Underwriters
pursuant to the exercise of such option as the number of Firm Shares purchased
by such Underwriter (set forth in Schedule A hereto) bears to the total number
of Firm Shares purchased by the several Underwriters (set forth in Schedule A
hereto), adjusted by the Representative in such manner as to avoid fractional
shares.  

              Delivery of definitive certificates for the Option Shares to be
purchased by the several Underwriters pursuant to the exercise of the option
granted by this Section 7 shall be made against payment of the purchase price
therefor by the several Underwriters by certified or official bank check or
checks drawn in next-day funds, payable to the order of the Company (and the
Company agrees not to deposit any such check in the bank on which it is drawn,
and not to take any other action with the purpose or effect of receiving
immediately available funds, until the business day following the date of its
delivery to the payee).  In the event of any breach of the foregoing, the
Company shall reimburse the Underwriters for the interest lost and any other
expenses borne by them by reason of such breach.  Such delivery and payment
shall take place at the offices of Brobeck, Phleger & Harrison LLP, 301 Congress
Avenue, Suite 1200, Austin, Texas or at such other place as may be agreed upon
between the Representative and the Company (i) on the Closing Date, if written
notice of the exercise of such option is received by the Company at least two
(2) full business days prior to the Closing Date, or (ii) on a date which shall
not be later than the third (3rd) full business day following the date the
Company receives written notice of the exercise of such option, if such notice
is received by the Company after the date two (2) full business days prior to
the Closing Date.

              The certificates for the Option Shares to be so delivered will be
made available to you at such office or such other location including, without
limitation, in New York City, as you may reasonably request for checking at
least one (1) full business day prior to the date of payment and delivery and
will be in such names and denominations as you may request, such request to be
made at least two (2) full business days prior to such date of payment and
delivery.  If the Representative so elects, delivery of the Option Shares may be
made by credit through full fast transfer to the accounts at The Depository
Trust Company designated by the Representative.

              It is understood that you, individually, and not as the
Representative of the several Underwriters, may (but shall not be obligated to)
make payment of the purchase price on


                                         -27-

<PAGE>


behalf of any Underwriter or Underwriters whose check or checks shall not have
been received by you prior to the date of payment and delivery for the Option
Shares to be purchased by such Underwriter or Underwriters.  Any such payment by
you shall not relieve any such Underwriter or Underwriters of any of its or
their obligations hereunder.

              (b)  Upon exercise of any option provided for in Section 7(a)
hereof, the obligations of the several Underwriters to purchase such Option
Shares will be subject (as of the date hereof and as of the date of payment and
delivery for such Option Shares) to the accuracy of and compliance with the
representations, warranties and agreements of the Company herein, to the
accuracy of the statements of the Company and officers of the Company made
pursuant to the provisions hereof, to the performance by the Company of its
obligations hereunder, to the conditions set forth in Section 6 hereof, and to
the condition that all proceedings taken at or prior to the payment date in
connection with the sale and transfer of such Option Shares shall be
satisfactory in form and substance to you and to Underwriters' Counsel, and you
shall have been furnished with all such documents, certificates and opinions as
you may request in order to evidence the accuracy and completeness of any of the
representations, warranties or statements, the performance of any of the
covenants or agreements of the Company or the satisfaction of any of the
conditions herein contained.

    8.   INDEMNIFICATION AND CONTRIBUTION.

              (a)  The Company agrees to indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject (including, without
limitation, in its capacity as an Underwriter or as a "qualified independent
underwriter" within the meaning of Schedule E of the Bylaws of the NASD), under
the Act, the Exchange Act or otherwise, specifically including, but not limited
to, losses, claims, damages or liabilities (or actions in respect thereof)
arising out of or based upon (i) any breach of any representation, warranty,
agreement or covenant of the Company herein contained, (ii) any untrue statement
or alleged untrue statement of any material fact contained in the Registration
Statement or any amendment or supplement thereto, or 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 (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading, and agrees to
reimburse each Underwriter for any legal or other expenses reasonably incurred
by it in connection with investigating or defending any such loss, claim,
damage, liability or action; PROVIDED, HOWEVER, that the Company shall not be
liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in the
Registration Statement, such Preliminary Prospectus or the Prospectus, or any
such amendment or supplement thereto, in reliance upon, and in conformity with,
written information relating to any Underwriter furnished to the Company by such
Underwriter, directly or through you, specifically for use in the preparation
thereof and, PROVIDED FURTHER, that the indemnity agreement provided in this
Section 8(a) with respect to any Preliminary


                                         -28-

<PAGE>


Prospectus shall not inure to the benefit of any Underwriter from whom the
person asserting any losses, claims, damages, liabilities or actions based upon
any untrue statement or alleged untrue statement of material fact or omission or
alleged omission to state therein a material fact purchased Shares, if a copy of
the Prospectus in which such untrue statement or alleged untrue statement or
omission or alleged omission was corrected had not been sent or given to such
person within the time required by the Act and the Rules and Regulations, unless
such failure is the result of noncompliance by the Company with Section 4(d)
hereof.

              The indemnity agreement in this Section 8(a) shall extend upon
the same terms and conditions to, and shall inure to the benefit of, each
person, if any, who controls any Underwriter within the meaning of the Act or
the Exchange Act.  This indemnity agreement shall be in addition to any
liabilities which the Company may otherwise have.

              (b)  Each Underwriter, severally and not jointly, agrees to
indemnify and hold harmless the Company against any losses, claims, damages or
liabilities, joint or several, to which the Company may become subject under the
Act or otherwise, specifically including, but not limited to, losses, claims,
damages or liabilities (or actions in respect thereof) arising out of or based
upon (i) any breach of any representation, warranty, agreement or covenant of
such Underwriter herein contained, (ii) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement or any
amendment or supplement thereto, or 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 (iii) any untrue statement or alleged
untrue statement of any material fact contained in any Preliminary Prospectus or
the Prospectus or any amendment or supplement thereto, or the omission or
alleged omission to state therein a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in the case of subparagraphs (ii) and (iii) of this
Section 8(b) to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by such
Underwriter, directly or through you, specifically for use in the preparation
thereof, and agrees to reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
any such loss, claim, damage, liability or action.

              The indemnity agreement in this Section 8(b) shall extend upon
the same terms and conditions to, and shall inure to the benefit of, each
officer of the Company who signed the Registration Statement and each director
of the Company, and each person, if any, who controls the Company within the
meaning of the Act or the Exchange Act.  This indemnity agreement shall be in
addition to any liabilities which each Underwriter may otherwise have.

              (c)  Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against any indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof, but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this


                                         -29-

<PAGE>


Section 8 except to the extent that it has been prejudiced by such omission.  In
case any such action is brought against any indemnified party, and it notified
the indemnifying party of the commencement thereof, the indemnifying party will
be entitled to participate therein and, to the extent that it shall elect by
written notice delivered to the indemnified party promptly after receiving the
aforesaid notice from such indemnified party, to assume the defense thereof,
with counsel reasonably satisfactory to such indemnified party; PROVIDED,
HOWEVER, that if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it which are different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate counsel to assume such
legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties.  Upon receipt of notice from the
indemnifying party to such indemnified party of the indemnifying party's
election so to assume the defense of such action and approval by the indemnified
party of counsel, the indemnifying party will not be liable to such indemnified
party under this Section 8 for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (together with appropriate local counsel) approved by the
indemnifying party representing all the indemnified parties under Section 8(a)
or 8(b) hereof who are parties to such action), (ii) the indemnifying party
shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of
commencement of the action or (iii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the
indemnifying party.  In no event shall any indemnifying party be liable in
respect of any amounts paid in settlement of any action unless the indemnifying
party shall have approved the terms of such settlement; PROVIDED that such
consent shall not be unreasonably withheld.  No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnification could have
been sought hereunder by such indemnified party, unless such settlement includes
an unconditional release of such indemnified party from all liability on all
claims that are the subject matter of such proceeding.

              (d)  In order to provide for just and equitable contribution in
any action in which a claim for indemnification is made pursuant to this Section
8 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 8 provides for
indemnification in such case, all the parties hereto shall contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that the Underwriters
severally and not jointly are responsible pro rata for the portion represented
by the percentage that the underwriting discount bears to the public offering
price, and the Company is responsible for the remaining portion, PROVIDED,
HOWEVER, that (i) no Underwriter shall be required to contribute any amount in
excess of the amount by which the underwriting discount applicable to the Shares
purchased by such Underwriter exceeds the amount of damages which such
Underwriter has otherwise been


                                         -30-

<PAGE>


required to pay and (ii) no person guilty of a fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who is not guilty of such fraudulent
misrepresentation.  The contribution agreement in this Section 8(d) shall extend
upon the same terms and conditions to, and shall inure to the benefit of, each
person, if any, who controls any Underwriter or the Company within the meaning
of the Act or the Exchange Act and each officer of the Company who signed the
Registration Statement and each director of the Company.

              (e)  The parties to this Agreement hereby acknowledge that they
are sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 8, and are fully informed regarding said provisions. 
They further acknowledge that the provisions of this Section 8 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement and Prospectus as required by the Act and the Exchange
Act.

    9.   REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS TO SURVIVE
DELIVERY.  All representations, warranties, covenants and agreements of the
Company and the Underwriters herein or in certificates delivered pursuant
hereto, and the indemnity and contribution agreements contained in Section 8
hereof shall remain operative and in full force and effect regardless of any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter within the meaning of the Act or the Exchange Act, or by or on
behalf of the Company, or any of its officers, directors or controlling persons
within the meaning of the Act or the Exchange Act, and shall survive the
delivery of the Shares to the several Underwriters hereunder or termination of
this Agreement.

    10.  SUBSTITUTION OF UNDERWRITERS.  If any Underwriter or Underwriters
shall fail to take up and pay for the number of Firm Shares agreed by such
Underwriter or Underwriters to be purchased hereunder upon tender of such Firm
Shares in accordance with the terms hereof, and if the aggregate number of Firm
Shares which such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed 10% of the Firm Shares, the remaining Underwriters
shall be obligated, severally in proportion to their respective commitments
hereunder, to take up and pay for the Firm Shares of such defaulting Underwriter
or Underwriters.

         If any Underwriter or Underwriters so defaults and the aggregate
number of Firm Shares which such defaulting Underwriter or Underwriters agreed
but failed to take up and pay for exceeds 10% of the Firm Shares, the remaining
Underwriters shall have the right, but shall not be obligated, to take up and
pay for (in such proportions as may be agreed upon among them) the Firm Shares
which the defaulting Underwriter or Underwriters so agreed but failed to
purchase.  If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares which the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for
twenty-four (24) hours to allow the several Underwriters the privilege of
substituting within twenty-four (24) hours (including non-business hours)
another underwriter or underwriters (which may include any nondefaulting
Underwriter) satisfactory to the Company.  If no such underwriter or
underwriters shall have been substituted as aforesaid by such postponed Closing
Date,


                                         -31-

<PAGE>


the Closing Date may, at the option of the Company, be postponed for a further
twenty-four (24) hours, if necessary, to allow the Company the privilege of
finding another underwriter or underwriters, satisfactory to you, to purchase
the Firm Shares which the defaulting Underwriter or Underwriters so agreed but
failed to purchase.  If it shall be arranged for the remaining Underwriters or
substituted underwriter or underwriters to take up the Firm Shares of the
defaulting Underwriter or Underwriters as provided in this Section 10, (i) the
Company shall have the right to postpone the time of delivery for a period of
not more than seven (7) full business days, in order to effect whatever changes
may thereby be made necessary in the Registration Statement or the Prospectus,
or in any other documents or arrangements, and the Company agrees promptly to
file any amendments to the Registration Statement, supplements to the Prospectus
or other such documents which may thereby be made necessary, and (ii) the
respective number of Firm Shares to be purchased by the remaining Underwriters
and substituted underwriter or underwriters shall be taken as the basis of their
underwriting obligation.  If the remaining Underwriters shall not take up and
pay for all such Firm Shares so agreed to be purchased by the defaulting
Underwriter or Underwriters or substitute another underwriter or underwriters as
aforesaid and the Company shall not find or shall not elect to seek another
underwriter or underwriters for such Firm Shares as aforesaid, then this
Agreement shall terminate.

         In the event of any termination of this Agreement pursuant to the
preceding paragraph of this Section 10, then, other than as set forth in the
Letter Agreement, the Company shall not be liable to any Underwriter (except as
provided in Sections 5 and 8 hereof) nor shall any Underwriter (other than an
Underwriter who shall have failed, otherwise than for some reason permitted
under this Agreement, to purchase the number of Firm Shares agreed by such
Underwriter to be purchased hereunder, which Underwriter shall remain liable to
the Company and the other Underwriters for damages, if any, resulting from such
default) be liable to the Company (except to the extent provided in Sections 5
and 8 hereof).

         The term "Underwriter" in this Agreement shall include any person
substituted for an Underwriter under this Section 10.

    11.  EFFECTIVE DATE OF THIS AGREEMENT AND TERMINATION.

              (a)  This Agreement shall become effective at the earlier of (i)
6:30 A.M., Pacific daylight savings time, on the first full business day
following the effective date of the Registration Statement, or (ii) the time of
the public offering of any of the Shares by the Underwriters after the
Registration Statement becomes effective.  The time of the public offering shall
mean the time of the release by you, for publication, of the first newspaper
advertisement relating to the Shares, or the time at which the Shares are first
generally offered by the Underwriters to the public by letter, telephone,
telegram or telecopy, whichever shall first occur.  By giving notice as set
forth in Section 12 before the time this Agreement becomes effective, you, as
Representative of the several Underwriters, or the Company, may prevent this
Agreement from becoming effective without liability of any party to any other
party, except as provided in Sections 4(i) and 8 hereof.

<PAGE>


                   (b)  You, as Representative of the several Underwriters,
shall have the right to terminate this Agreement by giving notice as hereinafter
specified at any time on or prior to the Closing Date or on or prior to any
later date on which Option Shares are to be purchased, as the case may be, (i)
if the Company shall have failed, refused or been unable to perform any
agreement on its part to be performed, or because any other condition of the
Underwriters' obligations hereunder required to be fulfilled is not fulfilled,
including, without limitation, any change in the condition (financial or
otherwise), earnings, operations, business or business prospects of the Company
from that set forth in the Registration Statement or Prospectus, which, in your
sole judgment, is material and adverse, or (ii) if additional governmental
restrictions, not in force and effect on the date hereof, shall have been
imposed upon trading in securities generally or minimum or maximum prices shall
have been generally established on the New York Stock Exchange or on the
American Stock Exchange or in the over the counter market by the NASD, or
trading in securities generally shall have been suspended on either such
exchange or in the over the counter market by the NASD, or if a banking
moratorium shall have been declared by federal, New York or California
authorities, or (iii) if the Company shall have sustained a loss by strike,
fire, flood, earthquake, accident or other calamity of such character as to
interfere materially with the conduct of the business and operations of the
Company regardless of whether or not such loss shall have been insured, or (iv)
if there shall have been a material adverse change in the general political or
economic conditions or financial markets as in your judgment makes it
inadvisable or impracticable to proceed with the offering, sale and delivery of
the Shares, or (v) if there shall have been an outbreak or escalation of
hostilities or of any other insurrection or armed conflict or the declaration by
the United States of a national emergency which, in the opinion of the
Representative, makes it impracticable or inadvisable to proceed with the public
offering of the Shares as contemplated by the Prospectus.  In the event of
termination pursuant to subparagraph (i) above, the Company shall remain
obligated to pay costs and expenses pursuant to Sections 4(i), 5 and 8 hereof. 
Any termination pursuant to any of subparagraphs (ii) through (v) above shall be
without liability of any party to any other party except as provided in Sections
4(i) and 8 hereof.

         If you elect to prevent this Agreement from becoming effective or to
terminate this Agreement as provided in this Section 11, you shall promptly
notify the Company by telephone, telecopy or telegram, in each case confirmed by
letter.  If the Company shall elect to prevent this Agreement from becoming
effective, the Company shall promptly notify you by telephone, telecopy or
telegram, in each case, confirmed by letter.

                           IWL COMMUNICATIONS, INCORPORATED
                                 COMMON STOCK WARRANT



THIS WARRANT AND THE SECURITIES ISSUABLE UPON THE EXERCISE HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND MAY NOT BE SOLD,
OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED UNLESS THERE IS
AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR THE COMPANY RECEIVES AN
OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH SALE OR TRANSFER IS
EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.


         This certifies that, for good and valuable consideration, receipt of
which is hereby acknowledged, Cruttenden Roth Incorporated ("HOLDER") is
entitled to purchase, subject to the terms and conditions of this Warrant, from
IWL Communications, Incorporated, a Texas corporation (the "COMPANY"),  125,000
fully paid and nonassessable shares of the Common Stock ("COMMON STOCK") of the
Company, in accordance with Section 2 during the period commencing one year from
the date hereof and ending on the earlier to occur of (i) at 5:00 p.m.
California time, April ____, 2002 (the "EXPIRATION DATE"), at which time this
Warrant will expire and become void unless earlier terminated as provided
herein.  The shares of Common Stock of the Company for which this Warrant is
exercisable as adjusted from time to time pursuant to the terms hereof, are
hereinafter referred to as the "SHARES."

         1.   EXERCISE PRICE.  The initial purchase price for the Shares shall
be $________ per share.  Such price shall be subject to adjustment pursuant to
the terms hereof (such price, as adjusted from time to time, is hereinafter
referred to as the "EXERCISE PRICE").

         2.   EXERCISE AND PAYMENT.  

              (a)  CASH EXERCISE.  At any time after April ____, 1998, this
Warrant may be exercised, in whole or in part, from time to time by the Holder,
during the term hereof, by surrender of this Warrant and the Notice of Exercise
annexed hereto duly completed and executed by the Holder to the Company at the
principal executive offices of the Company, together with payment in the amount
obtained by multiplying the Exercise Price then in effect by the number of
Shares thereby purchased, as designated in the Notice of Exercise.  Payment may
be in cash or by check payable to the order of the Company.  

              (b)  NET ISSUANCE.  In lieu of payment of the Exercise Price
described in Section 2(a), the Holder may elect to receive, without the payment
by the Holder of any additional consideration, shares equal to the value of this
Warrant or any portion hereof by the surrender of


                                          1.

<PAGE>


this Warrant or such portion to the Company, with the net issue election notice
annexed hereto (the "NET ISSUANCE ELECTION NOTICE") duly executed, at the office
of the Company.  Thereupon, the Company shall issue to the Holder such number of
fully paid and nonassessable shares of Common Stock as is computed using the
following formula:

where:                               X = Y (A-B)
                                         -------
                                            A

    X =  the number of shares to be issued to the Holder pursuant to this
         Section 2. 

    Y =  the number of shares covered by this Warrant in respect of which the
         net issuance election is made pursuant to this Section 2.

    A =  the fair market value of one share of Common Stock, as determined in
         accordance with the provisions of this Section 2.

    B =  the Exercise Price in effect under this Warrant at the time the net
         issuance election is made pursuant to this Section 2.

For purposes of this Section 2, the "FAIR MARKET VALUE" per share of the
Company's Common Stock shall mean:

              i.   If the Common Stock is traded on a national securities
    exchange or admitted to unlisted trading privileges on such an exchange, or
    is listed on the National Market (the "NATIONAL MARKET") of the National
    Association of Securities Dealers Automated Quotations System (the
    "NASDAQ") or other over-the-counter quotation system, the fair market value
    shall be the last reported sale price of the Common Stock on such exchange
    or on the Nasdaq National Market or other over-the-counter quotation system
    on the last business day before the effective date of exercise of the net
    issuance election or if no such sale is made on such day, the mean of the
    closing bid and asked prices for such day on such exchange, the Nasdaq
    National Market or over-the-counter quotation system; and 

              ii.  If the Common Stock is not so listed or admitted to unlisted
    trading privileges and bid and ask prices are not reported, the fair market
    value shall be the price per share which the Company could obtain from a
    willing buyer for shares sold by the Company from authorized but unissued
    shares, as such price shall be determined by mutual agreement of the
    Company and the Holder of this Warrant.  If the Company and the Holder
    cannot mutually agree on such price, the fair market value shall be made by
    an appraiser of recognized standing selected by the Holder and the Company,
    or, if they cannot agree on an appraiser, each of the Company and the
    Holder shall select an appraiser of recognized standing and the two
    appraisers shall designate a third appraiser of recognized standing, whose
    appraisal shall be determinative of such value.


                                          2.

         3.   DELIVERY OF STOCK CERTIFICATES.  Within a reasonable time after
exercise, in whole or in part, of this Warrant, the Company shall issue in the
name of and deliver to the Holder, a certificate or certificates for the number
of fully paid and nonassessable shares of Common Stock which the Holder shall
have requested in the Notice of Exercise or Net Issuance Election Notice.  If
this Warrant is exercised in part, the Company shall deliver to the Holder a new
Warrant for the unexercised portion of this Warrant at the time of delivery of
such stock certificate or certificates.

         4.   NO FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares will be issued upon exercise of this Warrant.  If upon any
exercise of this Warrant a fraction of a share results, the Company will pay the
Holder the difference between the cash value of the fractional share and the
portion of the Exercise Price allocable to the fractional share.

         5.   CHARGES, TAXES AND EXPENSES.  The Holder shall pay all transfer
taxes or other incidental charges, if any, in connection with the transfer of
the Shares purchased pursuant to the exercise hereof from the Company to the
Holder.

         6.   LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT.  Upon receipt
by the Company of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to the Company,
and upon reimbursement to the Company of all reasonable expenses incidental
thereto, and upon surrender and cancellation of this Warrant, if mutilated, the
Company will make and deliver a new Warrant of like tenor and dated as of such
cancellation, in lieu of this Warrant.

         7.   SATURDAYS, SUNDAYS, HOLIDAYS, ETC.  If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday or a Sunday or shall be a legal holiday, then such
action may be taken or such right may be exercised on the next succeeding
weekday which is not a legal holiday.

         8.   ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES.  The number of
and kind of securities purchasable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as follows:

              (a)  SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES.  If the
Company shall at any time after the date hereof but prior to the expiration of
this Warrant subdivide its outstanding securities as to which purchase rights
under this Warrant exist, by split-up or otherwise, or combine its outstanding
securities as to which purchase rights under this Warrant exist, the number of
Shares as to which this Warrant is exercisable as of the date of such
subdivision, split-up or combination shall forthwith be proportionately
increased in the case of a subdivision, or proportionately decreased in the case
of a combination.  Appropriate adjustments shall also be made to the purchase
price payable per share, but the aggregate purchase price payable for the total
number of Shares purchasable under this Warrant as of such date shall remain the
same.


                                          3.

<PAGE>


              (b)  STOCK DIVIDEND.  If at any time after the date hereof the
Company declares a dividend or other distribution on Common Stock payable in
Common Stock or other securities or rights convertible into Common Stock
("COMMON STOCK EQUIVALENTS") without payment of any consideration by such holder
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon exercise or
conversion thereof), then the number of shares of Common Stock for which this
Warrant may be exercised shall be increased as of the record date (or the date
of such dividend distribution if no record date is set) for determining which
holders of Common Stock shall be entitled to receive such dividend, in
proportion to the increase in the number of outstanding shares (and shares of
Common Stock issuable upon conversion of all such securities convertible into
Common Stock) of Common Stock as a result of such dividend, and the Exercise
Price shall be adjusted so that the aggregate amount payable for the purchase of
all the Shares issuable hereunder immediately after the record date (or on the
date of such distribution, if applicable), for such dividend shall equal the
aggregate amount so payable immediately before such record date (or on the date
of such distribution, if applicable).

              (c)  OTHER DISTRIBUTIONS.  If at any time after the date hereof
the Company distributes to holders of its Common Stock, other than as part of
its dissolution or liquidation or the winding up of its affairs, any shares of
its capital stock, any evidence of indebtedness or any of its assets (other than
cash, Common Stock or securities convertible into Common Stock), then the
Company may, at its option, either (i) decrease the per share Exercise Price of
this Warrant by an appropriate amount based upon the value distributed on each
share of Common Stock as determined in good faith by the Company's Board of
Directors or (ii) provide by resolution of the Company's Board of Directors that
on exercise of this Warrant, the Holder hereof shall thereafter be entitled to
receive, in addition to the shares of Common Stock otherwise receivable on
exercise hereof, the number of shares or other securities or property which
would have been received had this Warrant at the time been exercised.

              (d)  MERGER.  If at any time after the date hereof there shall be
a merger or consolidation of the Company with or into another corporation when
the Company is not the surviving corporation then the Holder shall thereafter be
entitled to receive upon exercise of this Warrant, during the period specified
herein and upon payment of the aggregate Exercise Price then in effect, the
number of shares or other securities or property of the successor corporation
resulting from such merger or consolidation, which would have been received by
Holder for the shares of stock subject to this Warrant had this Warrant at such
time been exercised.

              (e)  RECLASSIFICATION, ETC.  If at any time after the date hereof
there shall be a change or reclassification of the securities as to which
purchase rights under this Warrant exist into the same or a different number of
securities of any other class or classes, then the Holder shall thereafter be
entitled to receive upon exercise of this Warrant, during the period specified
herein and upon payment of the Exercise Price then in effect, the number of
shares or other securities or property resulting from such change or
reclassification, which would have been received by Holder for the shares of
stock subject to this Warrant had this Warrant at such time been exercised.


                                          4.

<PAGE>


         9.   NOTICE OF ADJUSTMENTS; NOTICES.  Whenever the Exercise Price or
number of Shares purchasable hereunder shall be adjusted pursuant to Section 8
hereof, the Company shall execute and deliver to the Holder a certificate
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated and
the Exercise Price and number of shares purchasable hereunder after giving
effect to such adjustment, and shall cause a copy of such certificate to be
mailed (by first class mail, postage prepaid) to the Holder.

         10.  RIGHTS AS SHAREHOLDER.  Prior to exercise of this Warrant, the
Holder shall not be entitled to any rights as a shareholder of the Company with
respect to the Shares, including (without limitation) the right to vote such
Shares, receive dividends or other distributions thereon, or be notified of
shareholder meetings, and the Holder shall not be entitled to any notice or
other communication concerning the business or affairs of the Company.  However,
in the event of any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend (other than a cash dividend) or other
distribution, any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to receive
any other right, the Company shall mail to each Holder of this Warrant, at least
10 days prior to the date specified therein, a notice specifying the date on
which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right. 

         11.  RESTRICTED SECURITIES.  The Holder understands that this Warrant
and the Shares purchasable hereunder constitute "RESTRICTED SECURITIES" under
the federal securities laws inasmuch as they are, or will be, acquired from the
Company in transactions not involving a public offering and accordingly may not,
under such laws and applicable regulations, be resold or transferred without
registration under the Securities Act of 1933, as amended (the "1933 ACT") or an
applicable exemption from such registration.  In this connection, the Holder
acknowledges that Rule 144 of the Securities and Exchange Commission (the "SEC")
is not now, and may not in the future be, available for resales of the Warrant
and the Shares purchasable hereunder. Unless the Shares are subsequently
registered pursuant to Section 14, the Holder further acknowledges that the
securities legend on Exhibit A to the Notice of Exercise attached hereto shall
be placed on any Shares issued to the Holder upon exercise of this Warrant.

         12.  CERTIFICATION OF INVESTMENT PURPOSE.  Unless a current
registration statement under the 1933 Act shall be in effect with respect to the
securities to be issued upon exercise of this Warrant, the Holder covenants and
agrees that, at the time of exercise hereof, it will deliver to the Company a
written certification executed by the Holder that the securities acquired by him
upon exercise hereof are for the account of such Holder and acquired for
investment purposes only and that such securities are not acquired with a view
to, or for sale in connection with, any distribution thereof.

         13.  DISPOSITION OF SHARES.  Holder hereby agrees not to make any
disposition of any Shares purchased hereunder unless and until:


                                          5.

<PAGE>


              (a)  Holder shall have notified the Company of the proposed
disposition and provided a written summary of the terms and conditions of the
proposed disposition;

              (b)  Holder shall have complied with all requirements of this
Warrant applicable to the disposition of the Shares; and

              (c)  Holder shall have provided the Company with written
assurances, in form and substance satisfactory to legal counsel of the Company,
that (i) the proposed disposition does not require registration of the Shares
under the 1933 Act or (ii) all appropriate action necessary for compliance with
the registration requirements of the 1933 Act or of any exemption from
registration available under the 1933 Act has been taken.

         The Company shall NOT be required (i) to transfer on its books any
Shares which have been sold or transferred in violation of the provisions of
this Section 13 or (ii) to treat as the owner of the Shares, or otherwise to
accord voting or dividend rights to, any transferee to whom the Shares have been
transferred in contravention of the terms of this Warrant.

         14.  REGISTRATION RIGHTS.

              (a)  PIGGYBACK REGISTRATION.  If at any time during the four-year
period commencing April ____, 1998 and ending on April ____, 2002, the Company
shall determine to register for its own account or the account of others under
the 1933 Act any of its equity securities, other than on Form S-4 or Form S-8 or
their then equivalents relating to equity securities to be issued solely in
connection with any acquisition of any entity or business, or equity securities
issuable in connection with stock option or other employee benefit plans, the
Company shall send to each Holder of Warrants or Shares, who is entitled to
registration rights under this Section 14(a) written notice of such
determination and, if within twenty (20) days after receipt of such notice, such
Holder shall so request in writing (hereafter a "SELLING HOLDER"), the Company
shall include in such Registration Statement all or any part of the Shares
issuable upon exercise of the Warrants (the "REGISTRABLE SECURITIES") such
Selling Holder requests to be registered.  The obligations of the Company under
this Section 14(a) may be waived by Holders holding a majority in interest of
the Registrable Securities.  In the event that the managing underwriter for said
offering advises the Company in writing that the inclusion of such securities in
the offering would be materially detrimental to the offering, then the Company
shall be required to include in the offering only that number of Registrable
Securities which the managing underwriter determines in its sole discretion will
not jeopardize the success of the offering (the securities so included to be
apportioned pro rata among all selling holders according to the total amount of
securities entitled to be included therein owned by each selling holder or in
such other proportions as shall mutually be agreed to by such selling holders);
PROVIDED HOWEVER, that in no event shall any Holder of Registrable Securities
have the number of shares of such securities reduced in such offer unless and
until any holders of non-Registrable Securities intending to participate in such
offering (which selling holders' registration rights, if any, were granted by
the Company from and after the date hereof) first shall have had the number of
their shares of such securities reduced up to the amount of securities the
managing underwriter has determined in its sole discretion shall be



                                          6.

<PAGE>

excluded from the offering; and PROVIDED FURTHER, that in no event shall any
shares being sold by a Holder properly exercising a demand registration granted
in Section 14(b) be excluded from such offering.  

              (b)  DEMAND REGISTRATION.  In addition to any Registration
Statement pursuant to subparagraph (a) above, during the four-year period
beginning on April ____, 1998 and ending on April ____, 2002, the Company will,
as promptly as practicable (but in any event within 60 days), after written
request (the "REQUEST") by the Holder, or by a person or persons holding (or
having the right to acquire by virtue of holding the Warrants) at least 50% of
the shares of Common Stock which have been (or may be) issued upon exercise of
the Warrants (such Holder or Holders to be included in the definition of
"SELLING HOLDER" for the purposes of Section 14(c) hereof), prepare and file at
its own expense a Registration Statement with the SEC and appropriate "blue sky"
authorities sufficient to permit the public offering of the Registrable
Securities and will use its best efforts at its own expense through its
officers, directors, auditors and counsel, in all matters necessary or
advisable, to cause such Registration Statement to become effective as promptly
as practicable and to maintain such effectiveness so as to permit resale of the
Shares covered by the Request until the earlier of the time that all such Shares
have been sold or the expiration of 90 days from the effective date of the
Registration Statement;  provided, however, that the Company shall only be
obligated to file one such Registration Statement under this Section 14(b).
         
              (c)  OBLIGATIONS OF THE HOLDERS.  In connection with the
registration of the Registrable Securities pursuant to either Sections 14(a) or
(b), the Selling Holders shall have the following obligations:

                   i.   It shall be a condition precedent to the obligations of
the Company to take any action pursuant to this Agreement with respect to each
Selling Holder that such Selling Holder shall furnish to the Company such
information regarding itself, the Registrable Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of the Registrable Securities
and shall execute such documents in connection with such registration as the
Company may reasonably request.  At least fifteen (15) days prior to the first
anticipated filing date of the Registration Statement, the Company shall notify
each Selling Holder of the information the Company requires from each such
Selling Holder (the "REQUESTED INFORMATION") in the case of a Registration
Statement being prepared pursuant to Section 14(b) or if such Selling Holder
elects to have any of such Selling Holder's Registrable Securities included in
the Registration Statement in the case of a Registration Statement being
prepared pursuant to Section 14(a).

                   ii.  Each Selling Holder by such Selling Holder's acceptance
of the Registrable Securities agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statement hereunder, unless such Selling Holder has notified the
Company in writing of such Selling Holder's election to exclude all of such
Selling Holder's Registrable Securities from the Registration Statement; and


                                          7.

<PAGE>


                   iii. No Selling Holder may participate in any underwritten
registration hereunder unless such Selling Holder (i) agrees to sell such
Selling Holder's Registrable Securities on the basis provided in any
underwriting arrangements, (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements, and (iii)
agrees to pay its pro rata share of all underwriting discounts and commissions
and other fees and expenses of investment bankers and any manager or managers of
such underwriting, except as provided in Section 14(d) below.

              (d)  EXPENSES OF REGISTRATION.  All expenses, other than
underwriting discounts and commissions and other fees and expenses of investment
bankers and other than brokerage commissions, incurred in connection with
registrations, filings or qualifications pursuant to Section 14(a) or 14(b),
including, without limitation, all registration, listing and qualifications
fees, printers and accounting fees and the fees and disbursements of counsel for
the Company and the Selling Holders, shall be borne by the Company; PROVIDED,
HOWEVER, that the Company shall only be required to bear the fees and
out-of-pocket expenses of one legal counsel selected by the Selling Holders in
connection with such registration.  

              (e)  INDEMNIFICATION.  In the event any Registrable Securities
are included in a Registration Statement under this Agreement:

                   i.   To the extent permitted by law, the Company will
indemnify and hold harmless each Selling Holder who holds such Registrable
Securities, the directors, if any, of such Selling Holder, the officers, if any,
of such Selling Holder, each person, if any, who controls any Selling Holder
within the meaning of the 1933 Act, any underwriter (as defined in the 1933 Act)
for the Selling Holders, the directors, if any, of such underwriter and the
officers, if any, of such underwriter, and each person, if any, who controls any
such underwriter within the meaning of the 1933 Act (each, an "INDEMNIFIED
PERSON"), against any losses, claims, damages, expenses or liabilities (joint or
several) (collectively, "CLAIMS") to which any of them may become subject under
the 1933 Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement when it first became effective, or any
related final prospectus, amendment or supplement thereto, or the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which the statements therein were made, not misleading (a "VIOLATION").  The
Company shall reimburse the Selling Holders and each such underwriter or
controlling person, promptly as such expenses are incurred and are due and
payable, for any legal fees or other reasonable expenses incurred by them in
connection with investigating or defending any such Claim.  Notwithstanding
anything to the contrary contained herein, the indemnification agreement
contained in this Section 14(e)(i) shall not apply in such case to the extent
any such Claim arising out of or based upon a Violation which occurs in reliance
upon and in conformity with information furnished in writing to the Company by
any Indemnified Person or underwriter for such Indemnified Person expressly for
use in connection with the preparation of the Registration


                                          8.

<PAGE>


Statement or any such amendment thereof or supplement thereto, and shall not
apply to amounts paid in settlement of any Claim if such settlement is effected
without the prior written consent of the Company, which consent shall not be
unreasonably withheld.  

              ii.  In connection with any Registration Statement in which a
Selling Holder is participating, each such Selling Holder agrees to indemnify
and hold harmless, to the same extent and in the same manner set forth in
Section 14(e)(i), the Company, each of its directors, each of its officers who
signs the Registration Statement, each person, if any, who controls the Company
within the meaning of the 1933 Act, any underwriter and any other shareholder
selling securities pursuant to the Registration Statement or any of its
directors or officers or any person who controls such shareholder or underwriter
within the meaning of the 1933 Act (collectively and together with an
Indemnified Person, an "INDEMNIFIED PARTY"), against any Claim to which any of
them may become subject, under the 1933 Act or otherwise, insofar as such Claim
arises out of or is based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished to the Company by such Selling
Holder expressly for use in connection with such Registration Statement, and
such Selling Holder will reimburse any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such Claim;
PROVIDED, HOWEVER, that the indemnity agreement contained in this Section
14(e)(ii) shall not apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of such Selling Holder,
which consent shall not be unreasonably withheld.

              iii. The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in any distribution to the same extent as provided
above, with respect to information furnished in writing by such persons
expressly for inclusion in the Registration Statement.

              iv.  Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 14(e) of notice of the commencement of any
action (including any governmental action), such Indemnified Person or
Indemnified Party shall, if a Claim in respect thereof is made against any
indemnifying party under this Section 14(e), deliver to the indemnifying party a
written notice of the commencement thereof and 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
control of the defense thereof with counsel mutually satisfactory to the
indemnifying parties; PROVIDED, HOWEVER, that an Indemnified Person or
Indemnified Party shall have the right to retain its own counsel, with the fees
and expenses to be paid by the indemnifying party, if, in the reasonable opinion
of counsel retained by the indemnifying party, the representation by such
counsel of the Indemnified Person or Indemnified Party and the indemnifying
party would be inappropriate due to actual or potential differing interests
between such Indemnified Person or Indemnified Party and any other party
represented by such counsel in such proceeding.  The Indemnifying Party shall
pay for only one separate legal counsel for the Indemnified Parties; such legal
counsel shall be selected by the Indemnified Parties holding a majority in
interest of the Registrable Securities.  The failure to deliver written notice
to the indemnifying party within a reasonable time of the commencement


                                         9.

<PAGE>


of any such action shall not relieve such indemnifying party of any liability to
the Indemnified Person or Indemnified Party under this Section 14(e), except to
the extent that the indemnifying party is prejudiced in its ability to defend
such action.  The indemnification required by this Section 14(e) shall be made
by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.

              v.   Notwithstanding any of the foregoing, if, in connection with
an underwritten public offering of Registrable Securities, the Company, the
Selling Holders and the underwriter(s) enter into an underwriting or purchase
agreement relating to such offering which contains provisions covering
indemnification and contribution among the parties, the indemnification and
contribution provisions of this Section 14(e) shall be deemed inoperative for
purposes of such offering.


              (f)  CONTRIBUTION.  To the extent any indemnification by an
indemnifying party is prohibited or limited by law, the indemnifying party
agrees to make the maximum contribution with respect to any amounts for which it
would otherwise be liable under Section 14(e) to the fullest extent permitted by
law; PROVIDED, HOWEVER, that (i) no contribution shall be made under
circumstances where the maker would not have been liable for indemnification
under the fault standards set forth in Section 14(e), (ii) no seller of
Registrable Securities guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from
any seller of Registrable Securities who was not guilty of such fraudulent
misrepresentation, and (iii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities.

              (g)  REPORTS UNDER EXCHANGE ACT.  With a view to making available
to the Holders the benefits of Rule 144 promulgated under the 1933 Act or any
other similar rule or regulation of the SEC that may at any time permit the
Holders to sell securities of the Company to the public without registration
("RULE 144"), the Company agrees to:

                   i.   make and keep public information available, as those
terms are understood and defined in Rule 144; and

                   ii.  file with the SEC in a timely manner all reports and
other documents required of the Company under the 1933 Act and the Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT"); and

                   iii. furnish to each Holder so long as such Holder owns
Registrable Securities, promptly upon request, (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144, (ii) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company,


                                         10.

<PAGE>


and (iii) such other information as may be reasonably requested to permit the
Holders to sell such securities without registration pursuant to Rule 144.

              (h)  ASSIGNMENT OF THE REGISTRATION RIGHTS.  The rights to have
the Company register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Holders to transferees or assignees of all or any
portion of such securities only if:  (i) the Holder agrees in writing with the
transferee or assignee to assign such rights, (ii) the Company is, within a
reasonable time after such transfer or assignment, furnished with written notice
of the name and address of such transferee or assignee (iii) such assignment is
in accordance with and permitted by law and all other agreements between the
transferor or assignor and the Company, including without limitation,
shareholder's agreements, warrants and subscription agreements, and the
transferor or assignor otherwise is not in material default of any obligation to
the Company under any such other agreement, and (iv) at or before the time the
Company received the written notice contemplated by clause (ii) of this sentence
the transferee or assignee agrees in writing with the Company to be bound by all
of the provisions contained herein.

              (i)  TERMINATION OF REGISTRATION RIGHTS.  No Holder of Warrants
or Shares shall be entitled to exercise any right provided for in this Section
14 at such time as such Holder would be able to dispose of all of its
Registrable Securities in any three (3) month period under SEC Rule 144 or any
successor rule thereto.

         15.  TRANSFERABILITY.    

              (a)  GENERAL.  This Warrant shall be transferable only on the
books of the Company maintained at its principal office in Houston, Texas or
wherever its principal office may then be located, upon delivery thereof duly
endorsed by the Holder or by its duly authorized attorney or representative,
accompanied by proper evidence of succession, assignment or authority to
transfer.  Upon any registration of transfer, the Company shall execute and
deliver new Warrants to the person entitled thereto.

              (b)  LIMITATIONS ON TRANSFER.  This Warrant shall not be sold,
transferred, assigned or hypothecated by the Holder except to (i) one or more
persons, each of whom on the date of transfer is an officer of the Holder; (ii)
a general partnership or general partnerships, the general partners of which are
the Holder and one or more persons, each of whom on the date of transfer is an
officer of the Holder; (iii) a successor to the Holder in any merger or
consolidation; (iv) a purchaser of all or substantially all of the Holder's
assets; or (v) any person receiving this Warrant from one or more of the persons
listed in this Section 15(b) at such person's or persons' death pursuant to
will, trust or the laws of intestate succession.  This Warrant may be divided or
combined, upon request to the Company by the Holder, into a certificate or
certificates representing the right to purchase the same aggregate number of
Shares.  
              
         16.  MISCELLANEOUS.


                                         11.

<PAGE>


              (a)  CONSTRUCTION.  Unless the context indicates otherwise, the
term "Holder" shall include any transferee or transferees of this Warrant
pursuant to Section 15(b), and the term "Warrant" shall include any and all
warrants outstanding pursuant to this Agreement, including those evidenced by a
certificate or certificates issued upon division, exchange, substitution or

EXHIBIT A


To: IWL COMMUNICATIONS, INCORPORATED                             


         In connection with the purchase by the undersigned of ___________
shares of the Common Stock (the "STOCK") of IWL Communications, Incorporated, a
Texas corporation (the "COMPANY"), upon exercise of that certain Common Stock
Warrant dated as of April ____, 1997, the undersigned hereby represents and
warrants as follows:

         1.   The shares of Stock to be received by the undersigned upon
exercise of the Warrant are being acquired for its own account, not as a nominee
or agent, and not with a view to resale or distribution of any part thereof, and
the undersigned has no present intention of selling, granting any participation
in, or otherwise distributing the same.  The undersigned further represents that
it does not have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person or to any third
person, with respect to the Stock.  The undersigned believes it has received all
the information it considers necessary or appropriate for deciding whether to
purchase the Stock.

         2.   The undersigned understands that the shares of Stock are
characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from the Company in transactions not
involving a public offering and that under such laws and applicable regulations
such securities may be resold without registration under the Securities Act of
1933, as amended (the "ACT"), only in certain limited circumstances.  In this
connection, the undersigned represents that it is familiar with SEC Rule 144, as
presently in effect, and understands the resale limitations imposed thereby and
by the Act.

         3.   Without in any way limiting the representations set forth above,
the undersigned agrees not to make any disposition of all or any portion of the
Stock unless and until:

              (a)  There is then in effect a registration statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

              (b)  (i) The undersigned shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
requested, the undersigned shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the Company that such disposition will not
require registration of such shares under the Act.  The Company will not require
an opinion of counsel for sales made pursuant to Rule 144 except in unusual
circumstances.

         4.   The undersigned understands the instruments evidencing the Stock
may bear the following legend:

         THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND MAY NOT BE SOLD,
OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED UNLESS THERE IS
AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR THE COMPANY RECEIVES AN
OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH SALE OR TRANSFER IS
EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

a specified portion of the shares entitled to vote is required by the Texas
Business Corporation Act, the act of the shareholders on that matter shall be

affirmative vote of the holders of a specified portion of the shares of any
class is required by the Texas Business Corporation Act, the act of the holders
of shares of that class on that matter shall be the affirmative vote of the
holders of a majority of shares of that class, rather than the affirmative vote

     Section 2.01.  PLACE OF MEETINGS.  Meetings of shareholders for all
purposes may be held at such time and place, within or without the State of
Texas, as shall be stated in the notice of the meeting or in a duly executed
waiver of notice thereof.

     Section 2.02.  ANNUAL MEETING.  An annual meeting of the shareholders,
commencing with the year 1997, shall be held in each year on a date to be

brought before the meeting.

     Section 2.03.  LIST OF SHAREHOLDERS.  The officer or agent having charge of

meeting of shareholders, except to the extent that the voting rights of the
shares of any class or classes are limited or denied by the Articles of
Incorporation.  At any meeting of the shareholders, every shareholder having the
right to vote shall be entitled to vote either in person or by proxy executed in
writing subscribed by the shareholder.  A telegram, telex, cablegram or similar
transmission by the shareholder, or a photographic, photostatic, facsimile or
similar reproduction of a writing executed by the shareholder shall be treated
as an execution in writing for purposes of this section.  No proxy shall be

below, any action required or permitted to be taken at a meeting of the
shareholders of the Corporation may be taken without a meeting if a consent in
writing setting forth the action so taken shall be signed by all of the
shareholders entitled to vote with respect to the subject matter thereof, and
such consent shall have the same force and effect as a unanimous vote of the
shareholders.

     The Articles of Incorporation may provide that any action required by the
Texas Business Corporation Act to be taken at any annual or special meeting of
shareholders, or any action that may be taken at any annual or special meeting
of shareholders, may be taken without a meeting, without prior notice, and
without a vote, if a consent or consents in writing, setting forth the action so
taken, shall be signed by the holder or holders of shares having not less than
the minimum number of votes that would be necessary to take such action at a
meeting at which the holders of all shares entitled to vote on the action were
present and voted.  If the Articles of Incorporation make such a provision, then
such written consent shall bear the date of signature of each shareholder who
signs the consent.  No written consent shall be effective to take the action
that is the subject of the consent unless, within sixty (60) days after the date
of the earliest dated consent delivered to the Corporation in the manner
required by the Texas Business Corporation Act, a consent or consents signed by
the holder or holders of shares having not less than the minimum number of votes
that would be necessary to take the action that is the subject of the consent

principal place of business, or an officer or agent of the Corporation having
custody of the books in which proceedings of meetings of shareholders are
recorded.  Delivery shall be by hand or certified or registered mail, return
receipt requested.  Delivery to the Corporation's principal place of business
shall be addressed to the president or principal executive officer of the
Corporation.

     A telegram, telex, cablegram, or similar transmission by a shareholder, or
a photographic, photostatic, facsimile or similar reproduction of a writing
signed by a shareholder shall be regarded as signed by the shareholder for
purposes of this section.  Prompt notice of the taking of any action by
shareholders without a meeting by less than unanimous written consent shall be
given to those shareholders who did not consent in writing to the action.

     Section 2.11.  TELEPHONE MEETINGS.  Subject to applicable notice provisions
and unless otherwise restricted by the Articles of Incorporation, shareholders
may participate in and hold a meeting by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and participation in such meeting shall
constitute presence in person at such meeting, except where a person's
participation is for the express purpose of objecting to the transaction of any
business on the ground that the meeting is not lawfully called or convened.

been elected and shall qualify.

     Section 3.03.  CHANGE IN NUMBER.  The number of directors may be increased
or decreased from time to time by resolution of the shareholders or the Board of
Directors of the Corporation, but no decrease shall have the effect of
shortening the term of any incumbent director.

plurality of the votes cast by the holders of shares entitled to vote in the

Bylaws, neither the business to be transacted at nor the purpose of any special
meeting need be specified in a notice or waiver of notice of such meeting.

     Section 3.09.  QUORUM.  At all meetings of the Board of Directors, the
presence of a majority of the number of the directors fixed by or in the manner
provided in the Articles of Incorporation or these Bylaws shall constitute a
quorum for the transaction of business unless a greater number is required by
law, the Articles of Incorporation or the Bylaws.  The act of a majority of the
directors present at any meeting at which there is a quorum shall be the act of
the Board of Directors unless the act of a greater number is required by law,
the Articles of Incorporation or by these Bylaws.

majority of the remaining directors though less than a quorum of the Board of
Directors.  A director elected to fill a vacancy shall be elected for the
unexpired term of such director's predecessor in office.  A directorship to be
filled by reason of an increase in the number of directors may be filled in
accordance with Section 3.12 of this Article III or, subject only to any 
limitations then contained in the Texas Business Corporation Act relating to the
number of directors that may be elected by the Board of Directors to fill newly-
created directorships, may be filled by the Board of Directors for a term of
office continuing only until the next election of one (1) or more directors by
the shareholders.

     Section 3.12.  VOTE OF SHAREHOLDERS TO FILL VACANCY.  Any vacancy occurring
in the Board of Directors or any directorship to be filled by reason of an
increase in the number of directors may be filled by election at any annual or
special meeting of shareholders called for that purpose.

     Section 3.13.  ACTION WITHOUT MEETING; TELEPHONE MEETINGS.  Unless
otherwise restricted by the Articles of Incorporation or these Bylaws, any
action required or permitted to be taken at a meeting of the Board of Directors
or of any committee designated by the Board of Directors may be taken without a
meeting if a consent in writing, setting forth the action so taken is signed by
all the members of the Board of Directors or committee, as the case may be. 
Such consent shall have the same force and effect as a unanimous vote at a
meeting and may be stated as such in any document or instrument filed with the
Secretary of State.  Subject to applicable notice provisions and unless
otherwise restricted by the Articles of Incorporation or these Bylaws, members
of the Board of Directors or members of any committee designated by the Board of
Directors may participate in and hold a meeting by means of conference telephone
or similar communications equipment by means of which all persons participating
in the meeting can hear each other, and participation in such meeting shall
constitute presence in person at such meeting, except where a person
participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

     Section 3.14.  CHAIR OF THE BOARD.  The Board of Directors may elect a
Chair of the Board to preside at their meetings and perform such other duties as
the Board may from time to time assign to the Chair.

     Section 3.15.  COMPENSATION.  Directors, as such, shall not receive any
stated salary for their services, but, by resolution of the Board a fixed sum
and expenses of attendance, if any, may 


                                       5

<PAGE>

be allowed for attendance at each regular or special meeting of the Board; 
provided that nothing herein contained shall be construed to preclude any 
director from serving the Corporation in any other capacity and receiving 
compensation therefor.  Members of any committee designated by the Board may, 
by resolution of the Board of Directors, be allowed like compensation for 
attending committee meetings.

     Section 3.16.  COMMITTEES.  The Board of Directors, by resolution adopted
by a majority of the full Board of Directors, may designate from among its
members one (1) or more committees, each of which shall be comprised of one (1)
or more of its members and may designate one (1) or more of its members as
alternate members of any committee, who may, subject to any limitations imposed
by the Board of Directors, replace absent or disqualified members at any meeting
of that committee.  Any such committee, except to the extent provided in said
resolution, shall have and may exercise all of the authority of the Board of
Directors in the management of the business and affairs of the Corporation,
except where action of the full Board of Directors is required by law or by the
Articles of Incorporation.  Any member of the committees may be removed by the
Board of Directors by the affirmative vote of a majority of the Board of
Directors, whenever in its judgment the best interests of the Corporation will
be served thereby.  The committees shall keep regular minutes of their
proceedings and report the same to the Board of Directors when required.


                                   ARTICLE IV.

                                     NOTICES

     Section 4.01.  METHOD.  Whenever by statute, the Articles of Incorporation
or these Bylaws, notice is required to be given to any director or shareholder,
and no provision is made as to how such notice shall be given, it shall not be
construed to mean personal notice, but any such notice may be given in writing,
either personally or by mail, postage prepaid, addressed to such director or
shareholder at such address as appears on the share transfer records of the
Corporation or in any other method permitted by law.  Any notice required or
permitted to be given by mail shall be deemed to be given at the time when the
same shall be thus deposited in the United States mail as aforesaid.

     Section 4.02.  WAIVER.  Whenever any notice is required to be given to any
shareholder or director of the Corporation by law, the Articles of Incorporation
or these Bylaws, a waiver thereof in writing signed by the person or persons
entitled to such notice, whether before or after the time stated in such notice,
shall be deemed equivalent to the giving of such notice.  Attendance of a
shareholder or director at a meeting shall constitute a waiver of notice of such
meeting, except where a shareholder or director attends for the express purpose
of objecting to the transaction of any business on the ground that the meeting
is not lawfully called or convened.  Consent in writing by a shareholder or
director to any action taken or resolution adopted by the shareholders or
directors of the Corporation shall constitute a waiver of any and all notices
required to be given in connection with such action or resolution.

majority of the members of the Board of Directors represented at a meeting of
the Board of Directors at which a quorum is represented, whenever in its
judgment the best interests of the Corporation will be served thereby; but such

Directors.  The Chief Executive Officer shall have general and active management
of the business and affairs of the Corporation, shall see that all orders and
resolutions of the Board are carried into effect, and shall perform such other
duties as the Board of Directors shall prescribe.  Such duties shall be
performed by the President of the Corporation if the Board of Directors does not
elect a Chief Executive Officer.

     Section 5.06.  PRESIDENT.  The President shall preside at all meetings of
the shareholders and the Board of Directors unless the Board shall choose to

special meetings of the Board of Directors, and shall perform such other duties
as may be prescribed by the Board of Directors or President, under whose
supervision the Secretary shall be.  The Secretary shall keep in safe custody
the seal of the Corporation and affix the same to any instrument requiring it,
and, when so affixed, it shall be attested by the Secretary's signature or by
the signature of the Treasurer or an Assistant Secretary.

     Section 5.09.  ASSISTANT SECRETARIES.  Each Assistant Secretary shall have

shall disburse the funds of the Corporation as may be ordered by the Board of
Directors, taking proper vouchers for such disbursements, and shall render to
the President and directors, at the regular meetings of the Board, or whenever
they may require it, an account of all the Treasurer's transactions as Treasurer
and of the financial condition of the Corporation, and shall perform such other
duties as the Board of Directors may prescribe.  If required by the Board of
Directors, the Treasurer shall give the Corporation a bond in such form in such
sum, and with surety or sureties as shall be satisfactory to the Board for the
faithful performance of the duties of the Treasurer's office and for the
restoration to the Corporation, in case of the Treasurer's death, resignation,

                                   ARTICLE VI.

                        CERTIFICATES REPRESENTING SHARES

     Section 6.01.  CERTIFICATES.  Certificates in such form as may be
determined by the Board of Directors shall be delivered representing all shares
to which shareholders are entitled.  Such certificates shall be consecutively
numbered and shall be entered in the books of the Corporation 


                                       8

<PAGE>

as they are issued.  Each certificate shall state on the face thereof the 
holder's name, the number and class of shares, and the par value of such 
shares or a statement that such shares are without par value.  They shall be 
signed by the President or a Vice President and the Secretary or an Assistant 
Secretary and may be sealed with the seal of the Corporation or a facsimile 
thereof.  If any certificate is countersigned by a transfer agent, or an 
assistant transfer agent or registered by a registrar, other than the 
Corporation or an employee of the Corporation, the signature of any such 
officer may be facsimile.  Shares may not be issued until the full amount of 
the consideration, fixed as provided by law, has been paid.

     Section 6.02.  LOST CERTIFICATES.  The Board of Directors may direct a new
certificate representing shares to be issued in place of any certificate
theretofore issued by the Corporation alleged to have been lost or destroyed,
upon the making of an affidavit of that fact by the person claiming the
certificate to be lost or destroyed.  When authorizing such issue of a new
certificate, the Board of Directors, in its discretion and as a condition
precedent to the issuance thereof, may require the owner of such lost or
destroyed certificate, or such owner's legal representative, to advertise the
same in such manner as it shall require and/or give the Corporation a bond in
such form, in such sum, and with such surety or sureties as it may direct as
indemnity against any claim that may be made against the Corporation with
respect to the certificate alleged to have been lost or destroyed.

     Section 6.03.  TRANSFER OF SHARES.  Except as is otherwise provided in
these Bylaws, shares of stock shall be transferable only on the books of the
Corporation by the holder thereof in person or by such holder's duly authorized
attorney.  Upon surrender to the Corporation or the transfer agent of the
Corporation of a certificate representing shares duly endorsed or accompanied by
proper evidence of succession, assignment or authority to transfer, it shall be
the duty of the Corporation or the transfer agent of the Corporation to issue a
new certificate to the person entitled thereto, cancel the old certificate and
record the transaction upon its books.

     Section 6.04.  REGISTERED SHAREHOLDERS.  Unless otherwise provided by
statute, the Corporation may regard the person in whose name any shares issued
by the Corporation are registered in the share transfer records of the
Corporation at any particular time (including, without limitation as of a record
date fixed pursuant to Sections 6.05 and 6.06) as the owner of those shares at
that time for purposes of voting those shares, receiving distributions thereon
or notices in respect thereof, transferring those shares, exercising rights of
dissent with respect to those shares, exercising or waiving any preemptive right
with respect to those shares, entering into agreements with respect to those
shares in accordance with the Texas Business Corporation Act or giving proxies
with respect to those shares.  Neither the Corporation nor any of its officers,
directors, employees or agents shall be liable for regarding that person as the
owner of those shares at that time for those purposes, regardless of whether
that person possesses a certificate for those shares.

     Section 6.05.  FIXING RECORD DATE FOR MATTERS OTHER THAN CONSENTS TO
ACTION.  For the purpose of determining shareholders entitled to notice of or to
vote at any meeting of shareholders or any adjournment thereof, or entitled to
receive a distribution by the Corporation (other than a distribution involving a
purchase or redemption by the Corporation of any of its own shares) or a share
dividend, or in order to make a determination of shareholders for any other
proper purpose (other than determining shareholders entitled to consent to
action by shareholders proposed to be taken without a meeting of shareholders),
the Board of Directors may provide that the share 


                                       9

<PAGE>

transfer records shall be closed for a stated period but not to exceed, in 
any case, sixty (60) days.  If the share transfer records shall be closed for 
the purpose of determining shareholders entitled to notice of or to vote at a 
meeting of shareholders, such records shall be closed for at least ten (10) 
days immediately preceding such meeting.  In lieu of closing the share 
transfer records, the Board of Directors may fix in advance a date as the 
record date for any such determination of shareholders, such date in any case 
to be not more than sixty (60) days, and, in the case of a meeting of 
shareholders, not less than ten (10) days, prior to the date on which the 
particular action requiring such determination of shareholders is to be 
taken.  If the share transfer records are not closed and no record date is 
fixed for the determination of shareholders entitled to notice of or to vote 
at a meeting of shareholders, or shareholders entitled to receive a 
distribution (other than a distribution involving a purchase or redemption by 
the Corporation of any of its own shares) or a share dividend, the date on 
which such notice of the meeting is mailed or the date on which the 
resolution of the Board of Directors declaring such distribution or share 
dividend is adopted, as the case may be, shall be the record date for such 
determination of shareholders.  When a determination of shareholders entitled 
to vote at any meeting of shareholders has been made as provided in this 
Section, such determination shall apply to any adjournment thereof, except 
where the determination has been made through the closing of the share 
transfer records and the stated period of closing has expired.

     Section 6.06.  FIXING RECORD DATE FOR CONSENTS TO ACTION.  Unless a record
date shall have previously been fixed or determined pursuant to this Article VI,
whenever action by shareholders is proposed to be taken by consent in writing
without a meeting of shareholders, the Board of Directors may fix a record date
for the purpose of determining shareholders entitled to consent to that action,
which record date shall not precede, and shall not be more than ten (10) days
after, the date upon which the resolution fixing the record date is adopted by
the Board of Directors.  If no record date has been fixed by the Board of
Directors and the prior action of the Board of Directors is not required by the
Texas Business Corporation Act, the record date for determining shareholders
entitled to consent to action in writing without a meeting shall be the first
date on which a signed written consent setting forth the action taken or
proposed to be taken is delivered to the Corporation by delivery to its
registered office, its principal place of business, or an officer or agent of
the Corporation having custody of the books in which proceedings of meetings of
shareholders are recorded.  Delivery shall be by hand or by certified or
registered mail, return receipt requested.  Delivery to the Corporation's
principal place of business shall be addressed to the President or the principal
executive officer of the Corporation.  If no record date shall have been affixed
by the Board of Directors and prior action of the Board of Directors is required
by statute, the record date for determining shareholders entitled to consent to
action in writing without a meeting shall be at the close of business on the
date on which the Board of Directors adopts resolution taking such prior action.

     Section 6.07.  DISTRIBUTION HELD IN SUSPENSE.  Distributions made by the
Corporation, including those that were payable but not paid to a holder of
shares or to such holder's heirs, successors or assigns, and have been held in
suspense by the Corporation or were paid or delivered by it into an escrow
account or to a trustee or custodian, shall be payable by the Corporation,
escrow agent, trustee or custodian to the holder of the shares as of the record
date determined for that distribution as provided in Section 6.05, or to such
holder's heirs, successors or assigns.


                                      10

<PAGE>

     Section 6.08.  JOINT OWNERS OF SHARES.  When shares are registered on the
books of the Corporation in the names of two (2) or more persons as joint owners
with the right of survivorship, after the death of a joint owner and before the
time that the Corporation receives actual written notice that parties other than
the surviving joint owner or owners claim an interest in the shares or any
distributions thereon, the Corporation may record on its books and otherwise
effect the transfer of those shares to any person, firm, or Corporation
(including that surviving joint owner individually) and pay any distributions
made in respect of those shares, in each case as if the surviving joint owner or
owners were the absolute owners of the shares.  The Corporation permitting such
a transfer by and making any distribution to such a surviving joint owner or
owners before the receipt of written notice from other parties claiming an
interest in those shares or distributions is discharged from all liability for
the transfer or payment so made; provided, however, that the discharge of the
Corporation from liability and the transfer of full legal and equitable title of
the shares in no way affects, reduces, or limits any cause of action existing in
favor of any owner of an interest in those shares or distributions against the
surviving owner or owners.


                                  ARTICLE VII.

                               GENERAL PROVISIONS

     Section 7.02.  RESERVES.  There may be created by resolution of the Board
of Directors out of the surplus of the Corporation such reserve or reserves as
the directors from time to time, in their discretion, think proper to provide
for contingencies, or to equalize distributions, or to repair or maintain any
property of the Corporation, or for such other purposes as the Board of
Directors shall think beneficial to the Corporation, and the Board of Directors
may modify or abolish any such reserve in the manner in which it was created.

     Section 7.03.  CHECKS.  All checks or demands for money and notes of the
Corporation shall be signed by such officer or officers or such other person or

fixed by resolution of the Board of Directors.

the Corporation and may be in such form as the Board of Directors may determine.
Said seal may be used by causing it or a facsimile thereof to be impressed or
affixed or reproduced or otherwise.

     Section 7.06.  INDEMNIFICATION.  The Corporation shall have the authority
to and shall indemnify and advance expenses to the directors, officers,
employees, agents of the Corporation or any other persons serving at the request
of the Corporation in such capacities in a manner and to the maximum extent
permitted by applicable state or federal law.  The Corporation may 


                                      11

<PAGE>

purchase and maintain liability insurance or make other arrangements for such 
obligations to the extent permitted by the Texas Business Corporation Act.

     Section 7.07.  TRANSACTIONS WITH DIRECTORS AND OFFICERS.  No contract or
transaction between the Corporation and one (1) or more of its directors or
officers, or between the Corporation and any other Corporation, partnership,
association, or other organization in which one (1) or more of its directors or
officers are directors or officers or have a financial interest, shall be void
or voidable solely for this reason, solely because the director or officer is
present at or participates in the meeting of the Board of Directors or committee
thereof that authorizes the contract or transaction, or solely because his, her,
its or their votes are counted for such purpose, if:

          (1)  The material facts as to such person's relationship or interest
     and as to the contract or transaction are disclosed or are known to the
     Board of Directors or the committee, and the Board of Directors or
     committee in good faith authorizes the contract or transaction by the
     affirmative vote of a majority of the disinterested directors, even though
     the disinterested directors be less than a quorum; or

          (2)  The material facts as to such person's relationship or interest
     and as to the contract or transaction are disclosed or are known to the
     shareholders entitled to vote thereon, and the contract or transaction is
     specifically approved in good faith by vote of the shareholders; or

          (3)  The contract or transaction is fair as to the Corporation as of
     the time it is authorized, approved or ratified by the Board of Directors,
     a committee thereof, or the shareholders.

Common or interested directors may be counted in determining the presence of a
quorum at a meeting of the Board of Directors or of a committee that authorizes
the contract or transaction.

     Section 7.08.  AMENDMENTS.  The Board of Directors may amend or repeal the
Bylaws of the Corporation or adopt new Bylaws, unless: (1) the Articles of
Incorporation or the Texas Business Corporation Act reserves the power
exclusively to the shareholders in whole or part; or (2) the shareholders in
amending, repealing or adopting a particular bylaw expressly provide that the
Board of Directors may not amend or repeal that bylaw.  Unless the Articles of

all or some portion of the Bylaws, the shareholders may amend, repeal or adopt
the Bylaws even though the Bylaws may also be amended, repealed or adopted by
the Board of Directors.

     Section 7.09.  TABLE OF CONTENTS; HEADINGS.  The Table of Contents and
headings used in these Bylaws have been inserted for convenience only and do not
constitute matters to be construed in interpretation.

                               IWL COMMUNICATIONS, INC.

                         EMPLOYEE INCENTIVE STOCK OPTION PLAN

1.  PURPOSE.

    The purpose of this Employee Incentive Stock Option Plan (the PLAN) is to
give officers and executive personnel (KEY EMPLOYEES) of IWL COMMUNICATIONS,
INC., a Texas Corporation (the COMPANY), an opportunity to acquire shares of the
common stock of the Company, without par value (COMMON STOCK), to provide an
incentive for key employees to continue to promote the best interests of the
Company and enhance its long-term performance, and to provide an incentive for
key employees to join or remain with the Company.

2.  ADMINISTRATION.

    (a)  BOARD OF DIRECTORS. The Plan shall be administered by the Board of
Directors of the Company (the BOARD), which, to the extent it shall determine,
may delegate its powers with respect to the administration of the Plan (except
its powers under Section 11(c)) to a committee (COMMITTEE) appointed by the
Board. If the Board chooses to appoint a Committee, references hereafter to the
Board (except in Section 11(c)) shall be deemed to refer to the Committee.
Notwithstanding the proceeding provisions of the Section, no member of the Board
may exercise discretion with respect to, or participate in the administration of
the Plan if, at any time within one year prior to such exercise or
participation, he or she has received stock, stock options, stock appreciation
rights or any other derivative security pursuant to the Plan or any other plan
of the Company or any affiliate thereof as to which any discretion is exercised.

    (b)  POWERS. Within the limits of the express provisions of the Plan, the
Board shall determine:

         (i)   the key employees to whom awards hereunder shall be granted,

         (ii)  the time or times at which such awards shall be granted,

         (iii) the form and amount of the awards, and

         (iv)  the limitations, restrictions and conditions applicable to any
               such award.

In making such determinations, the Board may take into account the nature of the
services rendered by such employees, or classes of employees, their present and
potential contributions to the Company's success and such other factors as the
Board in its discretion shall deem relevant.

    (c)  INTERPRETATIONS. Subject to the express provisions of the Plan, the
Board may interpret the Plan, prescribe, amend and rescind rules and regulations
relating to it, determine the terms and provisions of the respective awards and
make all other determinations it deems necessary or advisable for the
administration of the Plan.

    (d)  DETERMINATIONS. The determinations of the Board on all matters 
regarding the Plan shall be conclusive. A member of the Board shall only be 
liable for any action taken or determination made in bad faith.

<PAGE>

    (e)  NONUNIFORM DETERMINATIONS.  The Board's determinations under the 
Plan, including determinations as to the persons to receive awards, the 
provisions and restrictions of such awards and the agreements evidencing the 
same, need not be uniform and may be made by it selectively among persons who 
receive or are eligible to receive awards under the Plan, whether or not such 
persons are similarly situated.

3.  AWARDS UNDER THE PLAN.

    (a)  FORM.  Awards under the Plan may be granted in the form of Incentive 
Stock Options, as described in Section 4.

    (b)  MAXIMUM LIMITATIONS.  The aggregate number of shares of Common Stock 
available for grant under the Plan is 258,600, subject to adjustment pursuant 
to Section 7. Shares of Common Stock issued pursuant to the Plan may be 
either authorized but unissued shares or shares now or hereafter held in the 
treasury of the Company. In the event that any Option under the Plan expires 
unexercised or is terminated, surrendered or canceled without being 
exercised, in whole or in part, for any reason, the number of shares subject 
to such Option, or the unexercised, terminated, forfeited or unearned portion 
thereof, shall be added to the remaining number of shares available for grant 
under the Plan, including a grant to a former holder of such Option, upon 
such terms and conditions as the Board shall determine, which terms may be 
more or less favorable than those applicable to such former Option.

    (c)  TEN PERCENT SHAREHOLDER.  Notwithstanding any other provision 
contained herein, no key employee may receive an Incentive Stock Option under 
the Plan if such employee, at the time the award is granted, owns (as defined 
in Section 424(d) of the Internal Revenue Code, as amended (the CODE)) stock 
possessing more than 10% of the total combined voting power of all classes of 
stock of the Company, unless the option price for such Incentive Stock Option 
is at least 110% of the fair market value of the Common Stock subject to such 
Incentive Stock Option on the date of grant and such Option is not exercisable 
after the date five years from the date such Option is granted.

4.  INCENTIVE STOCK OPTIONS.

    It is intended that Incentive Stock Options granted under the Plan shall
constitute Incentive Stock Options within the meaning of Section 422 of the
Code.  Incentive Stock Options may be granted under the Plan for the purchase of
shares of Common Stock. Incentive Stock Options shall be in such form and upon
such conditions as the Board shall from time to time determine, subject to the
following:

    (a)  OPTION PRICES.  The option price of each Incentive Stock Option shall
be at least 100% of the fair market value of the Common Stock subject to such
Incentive Stock Option on the date of grant.

                                     2 
<PAGE>

    (b)  TERMS OF OPTIONS.  No Incentive Stock Option shall be exercisable
prior to vesting. Each Option Agreement shall include a vesting schedule which
shall show when the Option becomes exercisable; provided, however, that each
option shall vest at a rate of at !east twenty percent (20%) per year over a
period of five (5) years. The Board in its discretion may accelerate the above
vesting schedule or may grant options pursuant to more favorable vesting
schedules, but in no event shall any Incentive Stock Options be exercisable
after the date ten years from the date such Option is granted, nor shall any
vesting schedule impose upon the Company any obligation to retain the Optionee
in its employ or under contract for any period, or otherwise to change the
employment status of an Optionee who is an employee of the Company.

    (c)  LIMITATION ON AMOUNTS.  The aggregate fair market value (determined 
with respect to each Incentive Stock Option as of the time such Incentive 
Stock Option is granted) of the capital stock with respect to which Incentive 
Stock Options are exercisable for the first time by a key employee during any 
calendar year (under this Plan or any other p!an of the Company) shall not 
exceed $100,000.

5.  PROVISIONS APPLICABLE TO INCENTIVE STOCK OPTIONS.

    (a)  EXERCISE.  Incentive Stock Options shall be subject to such terms and
conditions, shall be exercisable at such time or times, and shall be evidenced
by such form of written option agreement between the optionee and the Company,
as the Board shall determine, provided that such determinations are not
inconsistent with other provisions of the Plan, or with Section 422 of the Code
or regulations thereunder.

    (b)  MANNER OF EXERCISE OF OPTIONS AND PAYMENT FOR COMMON STOCK.  Incentive
Stock Options may be exercised by an optionee by giving written notice to the
Secretary of the Company stating the number of shares of Common Stock with
respect to which the Incentive Stock Option is being exercised and tendering
payment therefor. At the time that an Incentive Stock Option granted under the
Plan, or any part thereof, is exercised, payment for the Common Stock issuable
thereupon shall be made in full in cash or by certified check or, if the Board
in its discretion agrees to accept, by a promissory note payable to the Company
by the Optionee, secured by the stock being purchased under the Option, and
pursuant to such other terms and conditions as the Board may decide. As soon as
reasonably possible following such exercise, a certificate representing shares
of Common Stock purchased, registered in the name of the optionee, shall be
delivered to the optionee.

6.  TRANSFERABILITY.

    No Incentive Stock Option may be transferred, assigned, pledged or
hypothecated (whether by operation of law or otherwise), except as provided by
will or the applicable laws of descent or distribution, and no Incentive Stock
Option shall be subject to execution, attachment or similar process.  Any
attempted assignment, transfer, pledge, hypothecation or other disposition of an
Incentive Stock Option or levy of attachment or similar process upon the
Incentive Stock Option not specifically permitted herein shall be null and void
and without effect. An Incentive Stock Option may be exercised only by a key
employee during his or her 

                                     3 
<PAGE>

lifetime, or pursuant to Section 10(c), by his or her estate or the person 
who acquires the right to exercise such Incentive Stock Option upon his or 
her death by bequest or inheritance.

7.  ADJUSTMENT PROVISIONS.

    The aggregate number of shares of Common Stock with respect to which
Incentive Stock Options may be granted, the aggregate number of shares of Common
Stock subject to each outstanding Incentive Stock Option, and the option price
per share of each such Incentive Stock Option, may all be appropriately adjusted
as the Board may determine for any increase or decrease in the number of shares
of issued Common Stock resulting from a subdivision or consolidation of shares,
whether through reorganization, recapitalization, stock split-up, stock
distribution or combination of shares, or the payment of a share dividend or
other increase or decrease in the number of such shares outstanding effected
without receipt of consideration by the Company. Adjustments under this Section
shall be made according to the sole discretion of the Board, and its decisions
shall be binding and conclusive.

8.  DISSOLUTION, MERGER AND CONSOLIDATION.

    Upon the dissolution or liquidation of the Company, or upon a merger or
consolidation of the Company in which the Company is not the surviving
corporation, each Incentive Stock Option granted hereunder shall expire as of
the effective date of such transaction; provided, however, that the Board shall
give at least 30 days' prior written notice of such event to each optionee
during which time he or she shall have a right to exercise his or her wholly or
partially unexercised VESTED OR NONVESTED Incentive Stock Option (without regard
to installment exercise limitations, if any) and, subject to prior expiration
pursuant to Section 10(b) or (c), each Incentive Stock Option shall be
exercisable after receipt of such written notice and prior to the effective date
of such transaction.

9.  EFFECTIVE DATE AND CONDITIONS SUBSEQUENT TO EFFECTIVE DATE.

    (a)  The Plan shall become effective on the date of the approval of the
Plan by the holders of a majority of the shares of Common Stock of the Company;
provided, however, that the adoption of the Plan is subject to such shareholder
approval within twelve (12) months before or after the date of adoption of the
Plan by the Board. The Plan shall be null and void and of no effect if the
foregoing condition is not fulfilled, and in such event each Incentive Stock
Option granted hereunder shall, notwithstanding any of the preceding provisions
of the Plan, be null and void and of no effect.

    (b)  No grant or award shall be made under the Plan more than 10 years from
the earlier of the date of adoption of the Plan by the Board and shareholder
approval hereof; provided, however, that the Plan and all Incentive Stock
Options granted under the Plan prior to such date shall remain in effect and
subject to adjustment and amendment as herein provided until they have been
satisfied or terminated in accordance with the terms of the respective grants or
awards and the related agreements.

                                     4 
<PAGE>

10.      TERMINATION OF EMPLOYMENT.

    (a)  Each Incentive Stock Option shall, unless sooner expired pursuant to
Section 10(b) or (c) below, expire on the first to occur of the tenth
anniversary of the date of grant thereof or the expiration date set forth in the
applicable option agreement.

    (b)  An Incentive Stock Option shall expire on the first to occur of the
applicable date set forth in paragraph (a) next above or the date that the
employment of the key employee with the Company terminates for any reason other
than death or disability.  Notwithstanding the preceding provisions of this
paragraph, the Board, in its sole discretion, may, by written notice given to an
ex-employee, permit the ex-employee to exercise Incentive Stock Options during a
period following his or her termination of employment, which period shall not
exceed thirty (30) days. In no event, however, may the Board permit an ex-
employee to exercise an Incentive Stock Option after the expiration date
contained in the agreement evidencing such Incentive Stock Option.
Notwithstanding the preceding provisions of this paragraph, if the Board permits
an ex-employee to exercise Incentive Stock Options during a period following his
or her termination of employment pursuant to such preceding provisions, such
Incentive Stock Options shall, to the extent unexercised, expire on the date
that such ex-employee violates (as determined by the Board) any covenant not to
compete in effect between the Company and the ex-employee or the date that such
employee discloses (as determined by the board) information of a confidential
nature about the company to a third party.

    (c)  If the employment of a key employee with the Company terminates by
reason of disability (as defined in Section 422(c)(6) of the Code and as
determined by the Board) or by reason of death, his or her Incentive Stock
Options shall expire on the first to occur of the date set forth in paragraph
(a) of this Section 10 or the first anniversary of such termination of
employment.

11. MISCELLANEOUS.

    (a)  LEGAL AND OTHER REQUIREMENTS.  The obligation of the Company to sell
and deliver Common Stock under the Plan shall be subject to all applicable laws,
regulations, rules and approvals, including, but not by way of limitation, the
effectiveness of a registration statement under the Securities Act of 1933 if
deemed necessary or appropriate by the Company. Certificates for shares of
Common Stock issued hereunder may be legended as the Board shall deem
appropriate.

    (b)  NO OBLIGATION TO EXERCISE OPTIONS. The granting of an Incentive Stock
Option shall impose no obligation upon an optionee to exercise such Incentive
Stock Option.

    (c)  TERMINATION AND AMENDMENT OF PLAN. The Board, without further action
on the part of the shareholders of the Company, may from time to time alter,
amend or suspend the Plan or any Incentive Stock Option granted hereunder or may
at any time terminate the Plan, except that it may not, without the approval of
the shareholders of the Company (except to the extent provided in Section 7
hereof):

                                     5 
<PAGE>

         (i)   Materially increase the total number of shares of Common Stock
    available for grant under the Plan except as provided in Section 7;

         (ii)  Materially modify the class of eligible employees under the Plan;

         (iii) Materially increase benefits to any key employee who is
    subject to the restrictions of Section 16 of the Securities Exchange Act of
    1934; or

         (iv)  Effect a change relating to Incentive Stock Options granted
    hereunder which is inconsistent with Section 422 of the Code or regulations
    issued thereunder. No action taken by the Board under this Section, either
    with or without the approval of the shareholders of the Company, may
    materially and adversely affect any outstanding Incentive Stock Option
    without the consent of the holder thereof;

    (d)  APPLICATION OF FUNDS.  The proceeds received by the Company from the
sale of Common Stock pursuant to Incentive Stock Options will be used for
general corporate purposes.

    (e)  WITHHOLDING TAXES.  Upon the exercise of any Incentive Stock Option
the Company shall have the right to require the optionee to remit to the Company
an amount sufficient to satisfy all federal, state and local withholding tax
requirements prior to the delivery of any certificate or certificates for shares
of Common Stock. In the event that the optionee disposes of any Common Stock
acquired by the exercise of an Incentive Stock Option within the two-year period
following grant, or within the one-year period following exercise, of the
Incentive Stock Option, the Company shall have the right to require the optionee
to remit to the Company an amount sufficient to satisfy all federal, state and
local withholding tax requirements as a condition to the registration of the
transfer of such Common Stock on its books. Whenever under the Plan payments are
to be made by the Company in cash or by check, such payments shall be net of any
amounts sufficient to satisfy all federal, state and local withholding tax
requirements.

    (f)  RIGHT TO TERMINATE EMPLOYMENT.  Nothing in the Plan or any agreement
entered into pursuant to the Plan shall confer upon any key employee or other
optionee the right to continue in the employment of the Company or any
subsidiary or affect any right which the Company or any subsidiary may have to
terminate the employment of such key employee or other optionee.

    (g)  RIGHTS AS A SHAREHOLDER. No optionee shall have any right as a
shareholder unless and until certificates for shares of Common Stock are issued
to him or her.

    (h)  LEAVES OF ABSENCE AND DISABILITY. The Board shall be entitled to make
such rules, regulations and determinations as it deems appropriate under the
Plan in respect of any leave of absence taken by or disability of any key
employee. Without limiting the generality of the foregoing, the Board shall be
entitled to determine (i) whether or not any such leave of absence shall
constitute a termination of employment within the meaning of the Plan, and (ii)
the 

                                      6 
<PAGE>

impact, if any, of any such leave of absence on awards under the Plan 
theretofore made to any key employee who takes such leave of absence.

    (i)  FAIR MARKET VALUE.  Whenever the fair market value of Common Stock 
is to be determined under the Plan as of a given date, such fair market value 
shall be:

         (i)   If the Common Stock is traded on the over-the-counter market, the
    average of the mean between the bid and the asked price for the Common
    Stock at the close of trading for the 10 consecutive trading days
    immediately preceding such given date;

         (ii)  If the Common Stock is listed on a national securities exchange,
    the average of the closing prices of the Common Stock on the Composite Tape
    for the 10 consecutive trading days immediately preceding such given date;
    and

         (iii) If the Common Stock is neither traded on the over-the-counter 
    market nor listed on a national securities exchange, such value as the 
    Board, in good faith, shall determine.

         Notwithstanding any provision of the Plan to the contrary, no 
determination made with respect to the fair market value of Common Stock subject
to an Incentive Stock Option shall be inconsistent with Section 422 of the Code
or regulations thereunder.

    (j)  NOTICES.  Every direction, revocation or notice authorized or required
by the Plan shall be deemed delivered to the Company (1) on the date it is
personally delivered to the Secretary of the Company at its principal executive
offices or (2) three business days after it is sent by registered or certified
mail, postage prepaid, addressed to the Secretary at such offices, and shall be
deemed delivered to an optionee (1) on the date it is personally delivered to
him or her or (2) three business days after it is sent by registered or
certified mail, postage prepaid, addressed to him or her at the last address
shown for him or her on the records of the Company.

    (k)  APPLICABLE LAW.  All questions pertaining to the validity, construction
and administration of the Plan and Stock Options granted hereunder shall be 
determined in conformity with the laws of the state of Texas, to the extent not 
inconsistent with Section 422 of the Code and regulations thereunder.

    (l)  ELIMINATION OF FRACTIONAL SHARES.  If under any provision of the Plan
which requires a computation of the number of shares of Common Stock subject to
an Incentive Stock Option the number so computed is not a whole number of shares
of Common Stock, such number of shares of Common Stock shall be rounded down to
the next whole number.

    (m)  STOCK REDEMPTION AGREEMENT.  Notwithstanding anything to the contrary
contained in the Plan, the Company shall be under no obligation to sell or
deliver Common Stock under the Plan to an optionee unless such optionee shall
execute a Stock Redemption Agreement with respect to such Common Stock,
substantially in the form of EXHIBIT A attached hereto.

     1.   PURPOSES OF THE PLAN.

     The purposes of this Stock Option Plan are to attract and retain the best
available personnel for positions of substantial responsibility, to provide
additional incentive to Employees and Consultants of the Company and its
Subsidiaries, and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory Stock
Options, as determined by the Administrator at the time of grant of an Option
and subject to the applicable provisions of Section 422 of the Code and the

the Plan and shall not become available for future distribution under the

     4.   ADMINISTRATION OF THE PLAN.

     (a)  INITIAL PLAN PROCEDURE. Prior to the date, if any, upon which the
Company becomes subject to the Exchange Act, the Plan shall be administered by
the Board or a Committee appointed by the Board.

     (b)  PLAN PROCEDURE AFTER THE DATE, IF ANY, UPON WHICH THE COMPANY BECOMES
SUBJECT TO THE EXCHANGE ACT.

          (i)  MULTIPLE ADMINISTRATIVE BODIES. If permitted by Rule 16b-3, the
     Plan may be administered by different bodies with respect to Directors,
     Officers, and Employees who are neither Directors nor Officers.

          (ii) ADMINISTRATION WITH RESPECT TO DIRECTORS AND OFFICERS.  With
     respect to grants of Options to Employees who are also Officers or
     Directors of the Company, the Plan shall be administered by (A) the Board,
     if the Board may administer the Plan in compliance with the rules under
     Rule 16b-3 relating to the disinterested administration of employee benefit
     plans under which Section 16(b) exempt discretionary grants and awards of
     equity securities are to be made, or (B) a Committee designated by the

     comply with the rules under Rule 16b-3 relating to the disinterested
     administration of employee benefit plans under which Section 16(b) exempt
     discretionary grants and awards of equity securities are to be made. Once
     appointed, such Committee shall continue to serve in its designated
     capacity until otherwise directed by the Board. From time to time the Board
     may increase the size of the Committee and appoint additional members
     thereof, remove members (with or without cause) and appoint new members in
     substitution therefor, fill vacancies, however caused, and remove all
     members of the Committee and thereafter directly administer the Plan, all
     to the extent permitted by the rules under Rule 16b-3 relating to the
     disinterested administration of employee benefit plans under which Section
     16(b) exempt discretionary grants and awards of equity securities are to be
     made.

          (iii)     ADMINISTRATION WITH RESPECT TO OTHER EMPLOYEES AND
     CONSULTANTS. With respect to grants of Options to Employees or Consultants
     who are neither Directors nor Officers of the Company, the Plan shall be
     administered by (A) the Board or (B) a Committee designated by the Board,
     which committee shall be constituted in such a manner as to satisfy
     Applicable Laws. Once appointed, such Committee shall continue to serve in
     its designated capacity until otherwise directed by the Board. From time to
     time the Board may increase the size of the Committee and appoint
     additional members thereof, remove members (with or without cause), and
     appoint new members in substitution therefor, fill vacancies, however


                                       4

<PAGE>

     caused, and remove all members of the Committee and thereafter directly
     administer the Plan, all to the extent permitted by the Applicable Laws.

     (c)  POWERS OF THE ADMINISTRATOR. Subject to the provisions of the Plan
and, in the case of a Committee, the specific duties delegated by the Board to
such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any stock exchange upon which the Common
Stock is listed, the Administrator shall have the authority in its discretion:

          (i)  to determine the Fair Market Value of the Common Stock, in
     accordance with Section 2(m) of the Plan;

          (ii) to select the Consultants and Employees to whom Options may from
     time to time be granted hereunder;

          (iii) to determine whether and to what extent Options or any
     combination thereof are granted hereunder;

          (iv) to determine the number of Shares to be covered by each such
     award granted hereunder;

          (v)  to approve forms of agreement for use under the Plan;

          (vi) to determine whether and under what circumstances an Option may
     be settled in cash under Section 9(e) instead of Common Stock;

          (vii) to determine the terms and conditions, not inconsistent with
     the terms of the Plan, of any award granted hereunder. Such terms and
     conditions include, but are not limited to, the exercise price, the time or
     times when Options may be exercised (which may be based on performance
     criteria), any vesting acceleration or waiver of forfeiture restrictions,
     and any restriction or limitation regarding any Option or the shares of
     Common Stock relating thereto, based in each case on such factors as the
     Administrator, in its sole discretion, shall determine;

          (viii) to reduce the exercise price of any Option to the then
     current Fair Market Value if the Fair Market Value of the Common Stock
     covered by such Option has declined since the date the Option was granted;
     and

          (ix) to construe and interpret the terms of the Plan and awards
     granted pursuant to the Plan.

     (d)  EFFECT OF ADMINISTRATOR'S DECISION. All decisions, determinations and
interpretations of the Administrator shall be final and binding on all Optionees
and any other holders of any Options.

     5.   ELIGIBILITY.

     (a)  Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

     (b)  Each Option shall be designated in the Option Agreement as either an
Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding
such designation, to the extent that the aggregate Fair Market Value of the
Shares with respect to which Incentive Stock Options are exercisable for the
first time by the Optionee during any calendar year (under all plans of the
Company or any Parent or Subsidiary) exceeds $100,000, such Options shall be
treated as Nonstatutory Stock Options. For purposes of this Section 5(b),
Incentive Stock Options shall be taken into account in the order in which they
were granted. The Fair Market Value of the Shares shall be determined as of the
time the Option with respect to such Shares is granted.

     (c)  Neither the Plan nor any Option shall confer upon any Optionee any
right with respect to continuation of his or her employment or consulting
relationship with the Company, nor shall it interfere in any way with his or her
right or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.

     6.   TERM OF PLAN.

     The Plan shall become effective upon the earlier to occur of its adoption
by the Board of Directors or its approval by the shareholders of the Company, as
described in Section 17 of the Plan. It shall continue in effect for a term of
ten (10) years unless sooner terminated under Section 13 of the Plan.

     7.   TERM OF OPTIONS.

     The term of each Option shall be the term stated in the Option Agreement;
provided, however, that the term shall be no more than ten (10) years from the
date of grant thereof. In the case of an Incentive Stock Option granted to an
Optionee who, at the time the  Option is granted, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement.

     8.   OPTION EXERCISE PRICE AND CONSIDERATION.

     (a)  The per share exercise price for the Shares to be issued upon exercise
of an Option shall be such price as is determined by the Administrator, but
shall be subject to the following:

          (i)  In the case of an Incentive Stock Option


                                       6

<PAGE>

               (A)  granted to an Employee who, at the time of grant of such
          Option, owns stock representing more than ten percent (10%) of the
          voting power of all classes of stock of the Company or any Parent or
          Subsidiary, the per Share exercise price shall not be less than 110%
          of the Fair Market Value per Share on the date of grant; and

               (B)  granted to any other Employee, the per Share exercise price
          shall not be less than 100% of the Fair Market Value per Share on the
          date of grant.

          (ii) In the case of a Nonstatutory Stock Option

               (A)  granted to a person who, at the time of grant of such
          Option, owns stock representing more than ten percent (10%) of the
          voting power of all classes of stock of the Company or any Parent or
          Subsidiary, the per Share exercise price shall not be less than 110%
          of the Fair Market Value per Share on the date of the grant; and

               (B)  granted to any other person, the per Share exercise price
          shall not be less than 85% of the Fair Market Value per Share on the
          date of grant.

     (b)  The consideration to be paid for the Shares to be issued upon exercise
of an Option, including the method of payment, shall be determined by the
Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (i) cash,
(ii) a check, (iii) a promissory note, (iv) other Shares that (A) in the case of
Shares acquired directly or indirectly from the Company, have been owned by the
Optionee for more than six months on the date of surrender, and (B) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which such Option shall be exercised, (v) delivery of a
properly executed exercise notice together with such other documentation as the
Administrator and a broker, if applicable, shall require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the exercise price, or (vi) any combination of the foregoing methods of
payment. In making its determination as to the type of consideration to accept,
the Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

     9.   EXERCISE OF OPTION.

     (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option granted
hereunder shall be exercisable at such times and under such conditions as
determined by the Administrator, including performance criteria with respect to
the Company and/or the Optionee, and as shall be permissible under the terms of
the Plan, but in no case at a rate of less than 20% per year over five (5) years
from the date the Option is granted.


                                       7

<PAGE>

     An Option may not be exercised for a fraction of a Share.  Exercise of an
Option in any manner shall result in a decrease in the number of Shares that
thereafter may be available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

     An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option Agreement by the person entitled to exercise the Option and full payment
for the Shares with respect to which the Option is exercised has been received
by the Company. Full payment may, as authorized by the Administrator, consist of
any consideration and method of payment allowable under Section 8(b) hereof.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote, receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment shall be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 11 hereof.

     (b)  TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP.  In the event of
termination of an Optionee's Continuous Status as an Employee or Consultant,
such Optionee may exercise his or her Option to the extent that the Optionee was
entitled to exercise it at the date of such termination; provided, however, that
such Option may be exercised only within such period of time as is determined by
the Administrator.  Such time period shall be at least thirty (30) days but
shall not, in the case of an Incentive Stock Option, exceed three (3) months
after the date of such termination and shall not, in any case, be later than the
expiration date of the term of such Option as set forth in the Option Agreement.
To the extent that the Optionee was not entitled to exercise the Option at the
date of such termination, or if the Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate.  An Optionee's Continuous Status as an Employee or Consultant shall
not be terminated in the event of Optionee's change of status from an Employee
to a Consultant or from a Consultant to an Employee; provided, however, that in
the event of an Optionee's change of status from an Employee to a Consultant,
any Incentive Stock Option granted to such Employee shall automatically convert
to a Nonstatutory Stock Option on the date three (3) months and one day
following such change of status.

     (c)  DISABILITY OF OPTIONEE.  In the event of termination of an Optionee's
Continuous Status as an Employee or Consultant as a result of his or her
disability, the Optionee may, but only within twelve (12) months from the date
of such termination (and in no event later than the expiration date of the term
of such Option as set forth in the Option Agreement), exercise the Option to the
extent he or she otherwise entitled to exercise it at the date of such
termination.  If such disability is not a "disability" as such term is defined
in Section 22(e)(3) of the Code, then in the case of an Incentive Stock Option
such Incentive Stock Option shall automatically cease to be treated as an
Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory
Stock Option on the day three months and one day following such termination. To
the extent that the Optionee was not entitled to 


                                       8

<PAGE>

exercise the Option at the date of termination, or if the Optionee does not 
exercise such Option to the extent so entitled within the time specified 
herein, the Option shall terminate, and the Shares covered by such Option 
shall revert to the Plan.

     (d)  DEATH OF OPTIONEE.  In the event of the death of an Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration date of the term of such
Option as set forth in the Option Agreement) by the Optionee's estate or by any
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent that the Optionee was entitled to exercise the Option on
the date of death.  If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after the
Optionee's death, the Optionee's estate or any person who acquires the right to
exercise the Option by bequest or inheritance does not exercise the Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

     (e)  BUYOUT PROVISIONS.  The Administrator may at any time offer to buy out
for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     10.  NON-TRANSFERABILITY OF OPTIONS.  

     An Incentive Stock Option shall not be transferrable except by will or by
the laws of descent and distribution and shall be exercisable during the
lifetime of the person to whom the Incentive Stock Option is granted only by
such person.  A Nonstatutory Stock Option shall not be transferrable except by
will or by the laws of descent and distribution or pursuant to a qualified
domestic relations order, as defined by the Code or by Title I of the Employee
Retirement Income Security Act of 1974, as amended, or the rules thereunder (a
"QDRO"), and shall be exercisable during the lifetime of the person to whom the
Option is granted only by such person or any transferee pursuant to a QDRO.

     11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

     (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company. The conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance 


                                       9

<PAGE>

by the Company of shares of stock of any class, or securities convertible 
into shares of stock of any class, shall affect, and no adjustment by reason 
thereof shall be made with respect to, the number or price of shares of 
Common Stock subject to an Option. 

     (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed dissolution
or liquidation of the Company, the Administrator shall notify the Optionee at
least fifteen (15) days prior to such proposed action. To the extent it has not
been previously exercised, the Option shall terminate immediately prior to the
consummation of such proposed action.

     (c)  MERGER OR ASSET SALE.  In the event of the merger of the Company into,
or the consolidation of the Company with, another corporation in which the
shareholders of the Company receive cash or securities of another issuer, or any
combination thereof, in exchange for their shares of Common Stock, or the sale
of all or substantially all of the assets of the Company, each outstanding
Option shall be assumed or an equivalent option or right substituted by the
successor corporation or a Parent or Subsidiary of the successor corporation. 
In the event that the successor corporation refuses to assume or substitute for
the Option, the Optionee shall fully vest in and have the right to exercise the
Option as to all of the Optioned Stock, including Shares as to which it would
not otherwise be vested or exercisable.  If an Option becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a merger,
consolidation or sale of assets, the Administrator shall notify the Optionee
that the Option shall be fully exercisable for a period of fifteen (15) days
from the date of such notice, and the Option shall terminate upon the expiration
of such period.  For the purposes of this paragraph, the Option shall be
considered assumed if, following the merger, consolidation or sale of assets,
the option confers the right to purchase or receive, for each Share of Optioned
Stock subject to the Option immediately prior to the merger, consolidation or
sale of assets, the consideration (whether stock, cash, or other securities or
property) received in the merger, consolidation or sale of assets by holders of
Common Stock for each Share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding Shares); provided,
however, that if such consideration received in the merger, consolidation or
sale of assets is not solely common stock of the successor corporation or its
Parent (if any), the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of
the Option, for each Share of Optioned Stock subject to the Option, to be solely
common stock of the successor corporation or its Parent (if any) equal in fair
market value to the per share consideration received by holders of Common Stock
in the merger, consolidation or sale of assets.

     12.  TIME OF GRANTING OPTIONS.

      The date of grant of an Option shall, for all purposes, be the date on
which the Administrator makes the determination granting such Option, or such
other date as is determined by the Administrator.  Notice of the determination
shall be given to each Employee or Consultant to whom an Option is so granted
within a reasonable time after the date of such grant.


                                      10

<PAGE>

     13.  AMENDMENT AND TERMINATION OF THE PLAN.

     (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend, alter,
suspend or discontinue the Plan, but no amendment, alteration, suspension or
discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent.  In addition, to
the extent necessary and desirable to comply with Rule 16b-3 or with Section 422
of the Code (or any other applicable law or regulation, including the
requirements of the NASD or an established stock exchange), the Company shall
obtain shareholder approval of any Plan amendment in such a manner and to such a
degree as required.

     (b)  EFFECT OF AMENDMENT OR TERMINATION.  Any amendment or termination of
the Plan shall not affect Options already granted, and such Options shall remain
in full force and effect as if this Plan had not been amended or terminated,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

     14.  CONDITIONS UPON ISSUANCE OF SHARES.

     Shares shall not be issued pursuant to the exercise of an Option unless the
exercise of such Option and the issuance and delivery of such Shares pursuant
thereto shall comply with all relevant provisions of law, including, without
limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules
and regulations promulgated thereunder, and the requirements of any stock
exchange upon which the Shares may then be listed or any automatic quotation
system upon which the Shares may then be quoted, and shall be further subject to
the approval of counsel for the Company with respect to such compliance.

     As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

     15.  RESERVATION OF SHARES.

     The Company, during the term of this Plan, shall at all times reserve and
keep available such number of Shares as shall be sufficient to satisfy the
requirements of the Plan.

     The inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.


                                      11

<PAGE>

     16.  AGREEMENTS.

     Options shall be evidenced by Option Agreements in such form as the
Administrator shall approve from time to time.

     17.  SHAREHOLDER APPROVAL.  

     Continuance of the Plan shall be subject to approval by the shareholders of
the Company within twelve (12) months before or after the date the Plan is
adopted.  Such shareholder approval shall be obtained in the degree and manner
required under Applicable Laws and the rules of any stock exchange upon which
the Common Stock is listed or any automatic quotation system upon which the
Common Stock is quoted.

     18.  INFORMATION TO OPTIONEES AND PURCHASERS.

     The Company shall provide to each Optionee and to each individual who
acquires Shares pursuant to the Plan, not less frequently than annually during
the period such Optionee or purchaser has one or more Options outstanding, and,
in the case of an individual who acquires Shares pursuant to the Plan, during
the period such individual owns such Shares, copies of annual financial
statements.  The Company shall not be required to provide such statements to key
employees whose duties in connection with the Company assure their access to
equivalent information.

     II.  AGREEMENT

     1.   GRANT OF OPTION.  IWL Communications, Incorporated (the "Company")
hereby grants to the Optionee named in Section I hereof (the "Optionee") an
option (the"Option") to purchase the total number of shares of Common Stock (the
"Shares") set forth in Section I hereof, at the exercise price per share set
forth in Section I hereof (the "Exercise Price") subject to the terms,
definitions and provisions of the 1997 Stock Option Plan (the "Plan") adopted by
the Company, which is incorporated herein by reference.  Unless otherwise
defined herein, the terms defined in the Plan shall have the same defined
meanings in this Option Agreement.

     If designated in Section I hereof as an Incentive Stock Option, this Option
is intended to qualify as an Incentive Stock Option as defined in Section 422 of
the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code
Section 422(d), this Option shall be treated as a Nonstatutory Stock Option.

     2.   EXERCISE OF OPTION.

     (a)  RIGHT TO EXERCISE.  This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in Section I hereof and with the
applicable provisions of the Plan and this Option Agreement. In the event of
Optionee's death, disability or other termination of the employment or
consulting relationship, this Option shall be exercisable in accordance with the
applicable provisions of the Plan and this Option Agreement.

     (b)  METHOD OF EXERCISE.  This Option shall be exercisable by written
notice (in the form attached hereto as EXHIBIT A) which shall state the election
to exercise the Option, the number of Shares in respect of which the Option is
being exercised, and such other representations and agreements as to the
holder's investment intent with respect to such shares of Common Stock as may be
required by the Company pursuant to the provisions of the Plan.  Such written
notice shall be 


                                      14

<PAGE>

signed by the Optionee and shall be delivered in person or by certified mail 
to the Secretary of the Company.  The written notice shall be accompanied by 
payment of the Exercise Price.  This Option shall be deemed to be exercised 
upon receipt by the Company of such written notice accompanied by the 
Exercise Price.

     The Optionee shall, upon notification of the amount due (if any) as a
result of the exercise of the Option and prior to or concurrent with delivery of
the certificate representing the Shares, pay to the Company amounts necessary to
satisfy applicable federal, state and local tax withholding requirements.

     No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange upon which the Shares may then be listed
or any automatic quotation system upon which the Shares may then be quoted. 
Assuming such compliance, for income tax purposes the Shares shall be considered
transferred to the Optionee on the date on which the Option is exercised with
respect to such Shares.

     3.   LOCK-UP PERIOD.  Optionee hereby agrees that if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act of 1933, as amended (the "Securities Act"),
Optionee shall not sell or otherwise transfer any Shares or other securities of
the Company during the one-year period (or such longer period as may be
requested in writing by the Managing Underwriter and agreed to in writing by the
Company) (the "Market Standoff Period") following the effective date of a
registration statement of the Company filed under the Securities Act; provided,
however, that such restriction shall apply only to the first registration
statement of the Company to become effective under the Securities Act that
includes securities to be sold on behalf of the Company to the public in an
underwritten public offering under the Securities Act.  The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such Market Standoff Period.

     4.   METHOD OF PAYMENT.  Payment of the Exercise Price shall be by any of
the following, or a combination thereof, at the election of the Optionee:

     (a)  cash;

     (b)  check;

     (c)  surrender of other shares of Common Stock of the Company that (A) in
the case of Shares acquired directly or indirectly from the Company, have been
owned by the Optionee for more than six (6) months on the date of surrender, and
(B) have a Fair Market Value on the date of surrender equal to the Exercise
Price of the Shares as to which the Option is being exercised; or  


                                      15

<PAGE>

     (d)  delivery of a properly executed exercise notice together with such
other documentation as the Administrator and the broker, if applicable, shall
require to effect an exercise of the Option and delivery to the Company of the
sale or loan proceeds required to pay the Exercise Price.

     5.   RESTRICTIONS ON EXERCISE.  This Option may not be exercised until such
time as the Plan has been approved by the shareholders of the Company, and may
not be exercised if the issuance of such Shares upon such exercise or the method
of payment of consideration for such shares would constitute a violation of any
applicable federal or state securities or other law or regulation, including any
rule under Part 207 of Title 12 of the Code of Federal Regulations as
promulgated by the Federal Reserve Board.

     6.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution or
as otherwise set forth in the Plan and may be exercised during the lifetime of
Optionee only by Optionee or a permitted transferee as set forth in the Plan. 
The terms of the Plan and this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

     7.   TERM OF OPTION.  This Option may be exercised only within the term set
out in Section I hereof, and may be exercised during such term only in

                        IWL COMMUNICATIONS, INCORPORATED

                         1997 DIRECTOR STOCK OPTION PLAN


     1.   PURPOSE.  The purpose of this 1997 Director Stock Option Plan (the
"Plan") of IWL Communications, Incorporated, a Texas corporation (the
"Company"), is to encourage ownership in the Company by outside directors of the
Company whose continued services are considered essential to the Company's
future progress and to provide them with a further incentive to remain as
directors of the Company.

     2.   ELIGIBILITY.  Options (each, an "Option") to purchase shares
("Shares") of the Company's common stock, par value $.01 per share ("Common
Stock"), may be granted only to Outside Directors.  An "Outside Director" is a
member of the Board of Directors of the Company ("Board of Directors") that is
not an Employee (each, an "Optionee").  "Employee" means any person, including
officers and directors, employed by the Company or any Parent or Subsidiary of
the Company.  The payment of a Director's fee by the Company shall not be
sufficient to constitute "employment" by the Company.  A "Parent" means a
"parent corporation," whether now or hereafter existing, as defined in Section
424(e) of the Internal Revenue Code of 1986, as amended to date and as it may be
hereafter amended from time to time (the "Code"), and a "Subsidiary" means a
"subsidiary corporation," whether now or hereafter existing, as defined in
Section 424(f) of the Code.

     3.   ADMINISTRATION

          (a)  BOARD OF DIRECTORS.  The Board of Directors of the Company shall
supervise and administer the Plan in compliance with the rules under Rule 16b-3
or any successor rule thereto ("Rule 16b-3") under the Securities Exchange Act
of 1934, as amended (the "Exchange Act").  All questions of interpretation of
the Plan or of any Options issued under it shall be determined by the Board of
Directors and such determination shall be final and binding upon all persons
having an interest in the Plan.  In the event it becomes necessary after the
date on which the Plan is adopted to have the Plan administered by a committee
of the Board of Directors, then a committee designated by the Board of Directors
will administer the Plan, which committee shall be constituted to comply with
the rules under Rule 16b-3 relating to the administration of employee benefit
plans for Outside Directors, and all references in the Plan to the Board of
Directors shall be deemed to be a reference to such committee.

          (b)  POWERS OF THE BOARD OF DIRECTORS.  Subject to the provisions of
the Plan and subject to the approval of any relevant authorities, including the
approval, if required, of any national market system or established stock
exchange upon which the Common Stock is quoted or listed, the Board of Directors
shall have the authority in its discretion:

               (i)  to determine the Fair Market Value of the Common Stock, in
     accordance with Section 5(b) of the Plan;


<PAGE>

               (ii) to determine the recipients of Options and the number of
     shares to be covered by each Option granted hereunder, including the number
     of shares to be covered by Options to be granted to an Optionee;

               (iii) to determine the terms and conditions, not inconsistent
     with the terms of the Plan, of any award granted hereunder.  Such terms and
     conditions include, but are not limited to, the exercise price, the time or
     times when Options may be exercised, any vesting, acceleration or waiver of
     forfeiture restrictions, and any restriction or limitation regarding any
     Option or the shares of Common Stock relating thereto, based in each case
     on such factors as the Board of Directors, in its sole discretion, shall
     determine; and

               (iv) to construe and interpret the terms of the Plan and awards
     granted pursuant to the Plan, and to amend, suspend or discontinue the Plan
     as provided for in Section 10 hereof.

     4.   STOCK SUBJECT TO THE PLAN

          (a)  MAXIMUM NUMBER OF SHARES.  The maximum number of shares which may
be issued under the Plan shall be 100,000 shares of Common Stock, subject to
adjustment as provided in Section 9 below.

          (b)  TERMINATION OF OPTIONS.  If any Option shall for any reason
expire or otherwise terminate without having been exercised in full, the stock
not purchased under such Option shall revert to and again become available for
issuance under the Plan unless the Plan shall have terminated; provided,
however, that shares of Common Stock that have been actually issued under the
Plan shall not be returned to the Plan and shall not become available for future
issuance under the Plan.  Shares that are withheld as payment of the Exercise
Price of any Options (as set forth in Section 5(f)) shall be deemed issued for
purposes of this Section.

          (c)  STOCK SUBJECT TO THE PLAN.  The stock subject to the Plan may be
unissued shares or reacquired shares, bought on the market or otherwise.

     5.   TERMS, CONDITIONS AND FORM OF OPTIONS

          (a)  OPTION AGREEMENT

               Each option agreement governing an Option ("Option Agreement")
shall be in the form attached hereto as Exhibit A.  In the event any provisions
of the Option Agreement and the Plan conflict, the provisions of the Plan shall
control.  The provisions of separate Options need not be identical, but each
Option Agreement shall include (through incorporation of provisions hereof by
reference in the Option or otherwise) the substance of each of the following
provisions set forth in this Section 5.

                                     2

<PAGE>

          (b)  OPTION EXERCISE PRICE.  The exercise price per share for each
Option granted under the Plan shall be equal to one hundred percent (100%) of
the fair market value of each such share ("Fair Market Value") on the date of
grant.  The Fair Market Value shall be equal to (i) if the Common Stock is
quoted or listed on any national market system or established stock exchange,
including without limitation the Nasdaq National Market (the "NASDAQ"), the
closing sales price for such stock on the date of determination (or, if no such
price is reported on such date, such price as reported on the nearest preceding
day) as quoted on such system or exchange (or the exchange with the greatest
volume of trading in the Common Stock), as reported in THE WALL STREET JOURNAL
or such other source as the Board of Directors deems reliable, or (ii) if the
Common Stock is quoted on the NASDAQ System (but not on the Nasdaq National
Market thereof) or is regularly quoted by a recognized securities dealer but
selling prices are not reported, the mean of the closing bid and asked prices
for the Common Stock on the date of determination (or if such prices are not
reported on such date, such prices as reported on the nearest preceding date),
as reported in THE WALL STREET JOURNAL or such other source as the Board of
Directors deems reliable; or (iii) if the fair market value is not determined
pursuant to (i) or (ii) above, the fair market value as determined in good faith
by the Board of Directors.

          (c)  OPTIONS NON-TRANSFERABLE.  No Option shall be transferable by the
Optionee otherwise than by will, by the laws of descent and distribution, or
pursuant to a qualified domestic relations order, as defined in the Code or
Title I of the Employee Retirement Security Act of 1974, as amended ("ERISA"),
or the rules thereunder ("QDRO"), and shall be exercised during the lifetime of
the Optionee only by such person or any transferee pursuant to a QDRO.  No
Option or interest therein may be transferred, assigned, pledged or hypothecated
by the Optionee during such person's lifetime, whether by operation of law or
otherwise, or be made subject to execution, attachment or similar process.

          (d)  EXERCISE PERIOD.  Subject to Section 7, each Option shall become
vested and exercisable as follows:  The Options will vest one-third on the day
preceding the first Annual Meeting of Shareholders of the Company held after the
date of grant and one-third on each of the two following anniversaries of that
date so long as Optionee continues to serve as a director of the Company.  In
the event an Optionee ceases to serve as a director of the Company, each such
Option may be exercised by the Optionee (or, in the event of such person's
death, by such person's administrator, executor or heirs), at any time within 12
months after the Optionee ceases to serve as a director, but only to the extent
such Option was exercisable at the time of such cessation of service.
Notwithstanding the foregoing, no Option shall be exercisable after the
expiration of 10 years from the date of grant.

          (e)  EXERCISE PROCEDURE.  Subject to Section 12, an Option shall be
deemed to be exercised when written notice ("Exercise Notice") of such exercise
has been given to the Company in accordance with the terms of the Option
Agreement by the person entitled to exercise the Option and full payment for the
shares of Common Stock with respect to which the Option is exercised has been
received by the Company.  Each Optionee who exercises an Option shall, upon
notification of the amount due (if any) and prior to or concurrent with delivery
of the certificate representing the shares, pay by cash or check to the Company
all amounts necessary to satisfy applicable federal, state

                                     3

<PAGE>

and local tax withholding requirements.  No Option may at any time be
exercised with respect to a fractional share.

          (f)  PAYMENT OF EXERCISE PRICE.  The purchase price of stock acquired
pursuant to an Option shall be paid, to the extent permitted by applicable
statutes and regulations at the time the Option is exercised, either (i) in cash
or check, or (ii) at the discretion of the Board of Directors in one or a
combination of the following ways, (A) by delivery to the Company of other
shares of Common Stock of the Company to be valued at their Fair Market Value on
the exercise date (provided that any shares acquired directly or indirectly from
the Company shall have been owned by the Optionee for more than six months on
the date of surrender), or (B) withholding of shares that would otherwise be
issued upon the exercise of the Option to be valued at their Fair Market Value
on the exercise date.  If the Fair Market Value of the number of whole shares
transferred or the number of whole shares subject to an Option surrendered is
less than the total exercise price of the Option, the shortfall must be made up
in cash or by check.

     6.   NONSTATUTORY OPTIONS.  All Options granted under the Plan shall be
nonstatutory Options not entitled to special tax treatment under Section 422 of
the Code.

     7.   EFFECTIVE DATE AND TERM

          The Plan was adopted by the Board of Directors and the shareholders of
the Company as of 5:00 p.m. on February 28, 1997 and became effective upon its
adoption.  The Plan shall continue in effect until it is terminated by action of
the Board, but such termination shall not affect the terms of any outstanding
Options.

     8.   LIMITATION OF RIGHTS

          (a)  NO RIGHT TO CONTINUE AS DIRECTOR.  Neither the Plan, nor the
granting of an Option nor any other action taken pursuant to the Plan, shall
constitute or be evidence of any agreement or understanding, express or implied,
that the Company will retain a director for any period of time.

          (b)  NO SHAREHOLDERS' RIGHTS FOR OPTIONEES.  Neither an Optionee nor
any person to whom an Option is transferred pursuant to the Plan shall be deemed
to be the holder of, or to have any of the rights of a holder with respect to,
any shares of Common Stock subject to such Option including, but not limited to,
rights to vote or to receive dividends, unless and until such person has
satisfied all requirements for exercise of the Option pursuant to its terms, the
certificates evidencing such shares have been issued and such person has become
a record holder of such shares.

     9.   ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER

          (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by the
shareholders of the Company, the aggregate number of shares of Common Stock
subject to Options, the number of shares of Common Stock subject to Options to
be granted on each event described in Section 5,

                                     4

<PAGE>

the number of shares of Common Stock covered by each outstanding Option and
the number of shares of Common Stock that have been authorized for issuance
under the Plan but as to which no Options have yet been granted or that have
been returned to the Plan upon cancellation or expiration of an Option, as
well as the price per share of Common Stock covered by each such outstanding
Option, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of issued shares of
Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the
Company shall not be deemed to have been "effected without receipt of
consideration."  Such adjustment shall be made by the Board of Directors,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an
Option.

          (b)  DISSOLUTION OR LIQUIDATION.  In the event of the proposed
dissolution or liquidation of the Company, each outstanding Option will
terminate immediately prior to the consummation of such proposed action.

          (c)  MERGER OR ASSET SALE.  In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger or consolidation
of the Company with or into another entity in which the shareholders of the
Company receive cash or securities of another issuer, or any combination
thereof, in exchange for their shares of Common Stock, each outstanding Option
shall be assumed or an equivalent option shall be substituted by such successor
entity or a parent or subsidiary of such successor entity.  For the purposes of
this Section, the Option shall be considered assumed if, following the merger,
consolidation or sale of assets, the Option confers the right to purchase, for
each share of Common Stock subject to the Option immediately prior to the
merger, consolidation or sale of assets, the consideration (whether stock, cash,
or other securities or property) received in the merger, consolidation or sale
of assets by holders of Common Stock for each share held on the effective date
of the consummation of the transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding shares of common stock).

     10.   AMENDMENT OF THE PLAN

          The Board of Directors may amend or terminate the Plan in any respect
whatsoever, provided that any such amendment or termination of the Plan shall
not affect Options already granted and such Options shall remain in full force
and effect as if the Plan had not been amended or terminated.

     11.  NOTICE

          Any written notice to the Company required by any of the provisions of
the Plan shall be addressed to the Secretary of the Company and shall become
effective when it is received.  Any

                                     5

<PAGE>

written notice to Optionees required by any provisions of the Plan shall be
addressed to the Optionee at the address on file with the Company and shall
become effective 3 days after it is mailed by certified mail, postage prepaid
to such address or at the time of delivery if delivered sooner by messenger or
overnight courier.

     12.  REGULATORY APPROVAL, COMPLIANCE AND OTHER MATTERS.

          (a)  Options shall not be exercised, and shares shall not be issued
upon such exercise, unless the exercise of such Option and the issuance and
delivery of such shares shall comply with all relevant provisions of law,
including, without limitation, any applicable state securities laws, the
Securities Act of 1933, as amended ("the Securities Act"), the Exchange Act, the
rules and regulations thereunder and the requirements of any stock exchange upon
which such shares may then be listed or approved for listing upon notice of
issuance, and such issuance shall be further subject to the approval of counsel
for the Company with respect to such compliance, including the availability of
an exemption from registration for the issuance and sale of such shares.  The
inability of the Company to obtain from any regulatory body the authority deemed
by the Company to be necessary for the lawful issuance and sale of any shares
under this Plan, or the unavailability of an exemption from registration for the
issuance and sale of any shares under this Plan, shall relieve the Company of
any liability with respect to the non-issuance or sale of such shares.

          (b)  OTHER CONDITIONS.  The Company may require any Optionee, or any
person to whom an Option is transferred pursuant to the Plan, as a condition to
exercising any such Option, (i) to give written assurances satisfactory to the
Company as to the Optionee's knowledge and experience in financial and business
matters and/or to employ a purchaser representative reasonably satisfactory to
the Company who is knowledgeable and experienced in financial and business
matter, and that he or she is capable of evaluating, alone or together with the
purchaser representative, the merits and risks of exercising the Option; (ii) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Option for such person's own account and not
with any present intention of selling or otherwise distributing the stock; and
(iii) to deliver such other documentation as may be necessary to comply with
federal and state securities laws.  These requirements, and any assurances given
pursuant to such requirements, shall be inoperative if (i) the issuance of the
shares upon the exercise of the Option has been registered under a then
currently effective registration statement under the Securities Act and all
applicable state securities laws, or (ii) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws.  The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the stock and may enter stop
transfer orders against the transfer of the shares of Common Stock issuable upon
the exercised Options.  The Company has no obligation to undertake registration
of Options or the shares of Common Stock issuable upon the exercise of Options.

          (c)  RULE 16b-3.  With respect to persons subject to Section 16 of the
Exchange Act, transactions under the Plan are intended to comply with all
applicable conditions of Rule 16b-3

                                     6

<PAGE>

and with respect to such persons all transactions shall be subject to such
conditions regardless of whether they are expressly set forth in the Plan or
the Option Agreement.  To the extent any provision of the Plan or action by
the Board of Directors fails to so comply, it shall not apply to such persons
or their transactions and shall be deemed null and void, to the extent
permitted by law and deemed advisable by the Board of Directors.

     13.  GOVERNING LAW.  The Plan and all rights and obligations thereunder
shall be construed in accordance with and governed by the laws of the state of
Texas without regard to its conflict of laws rules.

2.  PREMISES:

    2.1  PREMISES. Landlord hereby leases to Tenant and Tenant leases from
Landlord, for the term, at the rental and upon all of the conditions set forth
herein, that certain real property known by unit number and address specified in
Article 1.1 hereof, consisting of the approximate Area specified in Article 1.2
hereof, and which is referred to herein as the "Premises". The Premises are
depicted in EXHIBIT "A" attached hereto. The Premises are located in a building
(the "Building"), which building, the real property on which it is situated, and
any parking facilities or structures appurtenant thereto, are hereinafter
collectively referred to as the "Property", and described in EXHIBIT "B"
attached hereto.

    2.2  USE CLAUSE. Tenant is permitted to use the Premises for the purposes
specified in Article 1.3 hereof, and for no other purpose whatsoever. Tenant
shall obtain, at its own expense, all necessary governmental licenses and
permits, inclusive of any impact or use fees imposed by said governmental
bodies, for such use. Tenant shall not conduct any secondhand, auction,
distress, fire, bankruptcy or going-out-of-business sales.

    2.3  COMMON AREA. As long as the Lease remains in effect and Tenant is not
in default hereunder, Tenant shall have the nonexclusive right, in common with
the Landlord, other tenants, subtenants, employees and invitees, to use the
common areas of the Property, which include, but are not limited to: walkways,
patios, landscaped areas and parks, sidewalks, service corridors, recreational
facilities, restrooms, stairways, elevators, plazas, malls, throughways, parking
areas and roadways, provided that Landlord shall have the right at any time to
exclude therefrom such areas as Landlord may determine so long as access to the
Premises is not unreasonably denied.

3.  LEASE TERM:

    3.1  TERM.  The Term of this Lease shall be as defined in Article 1.4
hereof, commencing on the Lease Commencement Date specified in Article 1.5
hereof, and ending on the Lease Expiration Date specified in Article 1.6 
hereof, unless sooner terminated pursuant to any provision of this Lease.

    3.2  CHANGE IN LEASE COMMENCEMENT DATE.  If for any reason Landlord cannot
deliver possession of the Premises to Tenant on said Lease Commencement Date,
Landlord shall not be subject to any liability therefor, nor shall such failure
affect the validity of this Lease or the obligations of the Tenant hereunder.
However, in such case Tenant shall not be obligated under any provisions of this
Lease until possession of the Premises is tendered to Tenant, which date shall
be the new Lease Commencement Date, and the Lease Expiration Date shall remain
unchanged. In the event that Landlord shall permit Tenant to occupy Premises
prior to said Lease Commencement Date, such occupancy shall be subject to all of
the provisions of this Lease. Said early possession shall not advance the Lease
Expiration Date.

         Upon Landlord's or Tenant's request, the parties agree to execute in
writing an Addendum to certify the commencement date and expiration date hereof,
but this Lease shall not be affected in any manner if either party fails or
refuses to execute such Addendum.

4.  RENTS:

    4.1  PAYMENT.  All rents shall be payable in advance, without prior demand
or any right of offset or deduction, in monthly installments on the first day of
each calendar month of the Term hereof. Tenant shall pay all rents to Landlord
in lawful money of the United States of America at the address stated in Article
1.9(B) or to such other persons or at such other places as Landlord may
designate in writing.

         If the Lease Commencement Date occurs on a day other than the first
day of a calendar month, then all rents shall be prorated for the balance of
that month based upon the actual number of days the Lease is in effect during
said calendar month. The term "Lease Year", as hereinafter used, refers to each
successive twelve-month period beginning with the Lease Commencement Date, as it
may be adjusted pursuant to Article 3.2 hereof. Notwithstanding 

                                       2 
<PAGE>

anything to the contrary contained herein, after Lease expiration Landlord 
shall have the right to reconcile all rents billed, paid and/or owed by 
Tenant during the Term hereof and thereafter submit a final billing to 
Tenant. Upon receipt thereof, Tenant shall submit payment in full to Landlord 
within thirty (30) days.

    4.2  LATE FEES.  Should Tenant fail to pay when due any installment of rent
or any other sum payable to Landlord under the terms of this Lease, Landlord may
assess interest at eighteen percent (18%) from and after the date on which any
such sum shall be due and payable, and such interest, which shall be paid by
Tenant to Landlord at the time of payment of the delinquent sum; provided,
however, nothing charged hereby shall ever exceed the amount that may properly
be charged or recovered under the laws of the state in which the Premises are
located.

    4.3  BASE RENT.  Payment of Base Rent shall begin on the Base Rent
Commencement Date specified in Article 1.10. If the Base Rent Commencement Date
occurs on a day other than the first day of a calendar month, then Base Rent
shall be prorated for the balance of that month based upon the actual number of
days from the Base Rent Commencement Date through the last day of said calendar
month. The amount of each monthly installment of Base Rent for the Premises for
the entire term of this Lease shall be as specified in Article 1.11, subject to
adjustment pursuant to the following paragraph.

    4.4  ADDITIONAL RENT.  Commencing with the calendar year which follows the
year in which the Lease Commencement Date occurs and continuing thereafter for
each calendar year during the full term of this Lease, Landlord shall present to
Tenant prior to the beginning of each calendar year a statement of Tenant's
Forecast Additional Rental.

         As used herein, "TENANT'S FORECAST ADDITIONAL RENTAL" shall mean 
Landlord's reasonable estimate of Tenant's Additional Rental (defined below) 
for the coming calendar year.

    "TENANT'S ADDITIONAL RENTAL" as that term is used herein, shall be computed 
on a calendar year basis and shall mean the sum of Tenant's Percentage Share 
(defined below) of Operating Expenses (defined below), to the extent such sum 
exceeds Tenant's Percentage Share of Operating Expenses during the "Base Year". 
There is established under this lease a "BASE YEAR", which for these purposes is
the calendar year 1996. As used herein, "TENANT'S PERCENTAGE SHARE" shall mean a
fraction, the numerator of which is the total number of square feet of Net 
Rentable Area within the Leased Premises and the denominator of which is 95% of 
the total square footage of all Net Rentable Area in the Building. For the 
purposes of this lease, the "TENANT'S PERCENTAGE SHARE" shall be 14.7%; 
provided, however, that in the event that the amount of space leased by Tenant 
shall increase or decrease subsequent to the beginning date of the term of this 
lease, whether pursuant to an option to expand or otherwise, Tenant's 
Proportionate Share shall be appropriately adjusted by Landlord. *See Addendum 
for cap on certain Operating Expenses.

         No later than one hundred twenty (120) days after the end of the
calendar year in which the Commencement Date occurs and of each calendar year
thereafter during the term of this lease, Landlord shall provide Tenant a
statement comparing the Base Year's Operating Expenses for each such calendar
year and a statement prepared by Landlord comparing Tenant's Forecast Additional
Rental with Tenant's Additional Rental. In the event that Tenant's Forecast
Additional Rental actually paid by Tenant exceeds Tenant's Additional Rental for
said calendar year, Landlord shall pay Tenant (in the form of a credit against
rentals next due or, if these rentals next due are less than the amount owed
Tenant, Landlord shall pay the difference in the form of a check) an amount
equal to such excess. In the event that Tenant's Additional Rental exceeds
Tenant's Forecast Additional Rental for said calendar year, Tenant hereby agrees
to pay Landlord, within thirty (30) days of receipt of the statement, an amount
equal to such difference ("TENANT'S ADDITIONAL RENTAL ADJUSTMENT").  The
provisions of this paragraph shall survive any expiration, termination or
cancellation of this lease.

         Tenant, at Tenant's sole cost and expense, shall have the right, to be
exercised by written notice given to Landlord within one hundred eighty (180)
days after receipt of aforesaid statement showing Operating Expenses for the
preceding calendar year, to audit, at the place where Landlord maintains its
books and records, Landlord's books and records pertaining only to such


                                       3 
<PAGE>

Operating Expenses for three (3) preceding calendar years and Tenant's Base
Year, provided such audit commences within thirty (30) days after Tenant's
notice to Landlord and thereafter proceeds regularly and continuously to
conclusion, and that such audit does not unreasonably interfere with the
conduct of Landlord's business. Landlord agrees to cooperate in good faith with
Tenant in the conduct of any such audit.

         "OPERATING EXPENSES", for each calendar year, shall consist of all
operating costs (defined below) for the Property.

         For the purposes of this Lease, "OPERATING COSTS" shall mean all (or
where specified by Landlord as hereinafter permitted or required, an amortized
portion of) expenses, costs and accruals (excluding therefrom, however, specific
costs billed to or otherwise incurred for the particular benefit of specific
tenants of the Building) computed on an accrual basis, incurred or accrued in
connection with, or relating to, the ownership, maintenance, or operation of the
Property during each calendar year, including, but not limited to, the 
following:

         (1)  Management fees of the building manager, not to exceed four
percent (4%) of the gross rentals collected;

         (2)  wages and salaries, including taxes, insurance and benefits, of
all on and off-site employees engaged in operations, maintenance or access
control, as reasonably allocated by Landlord;

         (3)  cost of all supplies, tools, equipment and materials to the
extent used in operations and maintenance, as reasonably allocated by Landlord;

         (4)  cost of all utilities including, but not limited to, the cost of
electricity, the cost of water and the cost of power for heating, lighting, air
conditioning and ventilating;

         (5)  cost of all maintenance and service agreements and the equipment
therein, including, but not limited to, access control service, garage
operations, window cleaning, elevator maintenance, janitorial service and
landscaping maintenance.;

         (6)  cost of repairs and general maintenance (excluding repairs,
alterations and general maintenance paid by proceeds of insurance), or if and to
the extent Landlord so elects in order to reduce the amount of Operating
Expenses paid by tenants of the Property in any given year or years, Landlord
may at its option amortize such cost based upon any amortization schedule in
accordance with generally accepted accounting principals, in which event the
amortized portion of such repair and maintenance costs (whether such costs were
incurred in the same year or in any prior year) shall be included as an
Operating Cost in each year of the amortization schedule as selected by
Landlord;

         (7)  amortization of the cost (together with reasonable financing
charges and installation costs), based upon any amortization schedule in
accordance with generally accepted accounting principals, of any system,
apparatus, device, or equipment which is installed for the principal purpose
of(i) reducing Operating Expenses, (ii) promoting safety, or (iii) complying
with governmental requirements which become effective after the Commencement
Date, in each case whether such costs were incurred in the same year or in any
prior year;

         (8)  the cost of all insurance, including, but not limited to, the
cost of casualty, rental abatement and liability insurance, and insurance on
Landlord's personal property, plus the cost of all deductible payments made by
Landlord in connection therewith;

         (9)  the cost of reasonable legal and accounting fees; and

         (10) all taxes, assessments and governmental charges, whether or not
directly paid by Landlord, whether federal, state, county or municipal and
whether they be by taxing districts or authorities presently taxing the Property
and said common areas or by others subsequently created or otherwise, and any
other taxes and assessments attributable to the Property and said common 

                                       4 
<PAGE>

areas or their operation, excluding, however, taxes and assessments 
attributable to the personal property of other tenants, federal and state 
taxes on income, death taxes, franchise taxes, and any taxes imposed or 
measured on or by the income of Landlord from the operation of the Property; 
provided, however, that if at any time during the term of this lease, the 
present method of taxation or assessment shall be so changed that the whole 
or any part of the taxes, assessments, levies, impositions or changes now 
levied, assessed or imposed on real estate and the improvements thereon shall 
be discontinued and as a substitute therefor, or in lieu of or in addition 
thereto, taxes, assessments, levies, impositions or charges shall be levied, 
assessed or imposed, wholly or partially, as a capital levy or otherwise, on 
the rents received from the Property or the rents reserved herein or any part 
thereof, then such substitute or additional taxes, assessments, levies, 
impositions or charges, to the extent so levied, assessed or imposed with 
respect to the Property, shall be deemed to be included within the operating 
costs. Consultation, legal fees and costs resulting from any challenge of tax 
assessments as reasonably allocated by Landlord shall also be included in 
operating costs. It is agreed that Tenant will be responsible for ad valorem 
taxes on its personal property and on the value of the leasehold improvements 
in the Leased Premises to the extent that the same exceed Building standard 
allowances. In the case of special taxes and assessments which may be payable 
in installments, only the amount of each installment accruing during a 
calendar year shall be included in the operating costs for such year.

         Notwithstanding any language contained herein to the contrary, Tenant
hereby agrees that, during any calendar year in which the entire Building is not
completely occupied, Landlord shall compute all Variable Operating Costs
(defined below) for such calendar year at 95% occupancy. For purposes of this
lease, the term "VARIABLE OPERATING COSTS" shall mean any operating cost that is
variable with the level of occupancy of the Building (e.g., tenant utilities and
tenant cleaning services). In the event that Landlord excludes from "OPERATING
COSTS" any specific costs billed to or otherwise incurred for the particular
benefit of specific tenants of the Building, Landlord shall have the right to
increase "OPERATING COSTS" by an amount equal to the cost of providing standard
services similar to the services for which such excluded specific costs were
billed or incurred.

         Notwithstanding anything to the contrary in this Section 5.4, the
following items shall be expressly excluded from Operating Costs:

         (1)  Repairs or other work occasioned by (i) fire, windstorm, or other
casualty of the type which Landlord has insured or is required to insure
pursuant to the terms of this Lease, or (ii) by the exercise of the right of
eminent domain;

other expenses incurred in connection with negotiations or disputes with other

         (3)  Expenses incurred in tenant buildout, renovating, or otherwise
improving or decorating, painting, or redecorating space for other tenants or
other occupants of vacant space;

         (4)  Costs incurred by Landlord for alterations which are considered
capital improvements, capital repairs, capital equipment and capital tools all
in conformity with generally accepted accounting principals consistently
applied, except to the extent included as an operating cost under clauses (6) or
(7) of the preceding definition of operations costs.

         (5)  Depreciation and amortization, except to the extent included as
an operating cost under clauses (6) or (7) of the preceding definition of
operations costs.

         (6)  All other costs of a capital nature, including, but not limited
to, capital improvements, capital repairs, capital equipment and capital tools

applied, except to the extent included as an operating cost under clauses (6) or
(7) of the preceding definition of operations costs.

         (7)  Expenses in connection with services or other benefits of a type
which are not 

                                       5

         (9)  Overhead and profit increment paid to subsidiaries or other

         (10) Payments of principal and/or interest on debt or amortization
payments on any mortgage or mortgages executed by Landlord covering the

         (11) All general administrative overhead expenses of Landlord for
services not specifically performed for the Building;

         (12) Any compensation paid to clerks, attendants or other persons in
commercial concessions operated by Landlord;

         (13) All items and services for which Tenant pays directly to third
parties or for which Tenant reimburses Landlord or pays third persons or for or

volts single phase or its equivalent consumption at a higher voltage, (ii) heat

                                       6 
<PAGE>

required for the comfortable occupation of the Premises during the following 
Building Operating Hours: 8:00 a.m. to 6:00 p.m. weekdays and 8:00 a.m. to 
1:00 p.m. on Saturdays (exclusive of Sundays and state and national holidays) 
or such shorter period specified or prescribed by any applicable policies or 
regulations adopted by any utility or government agency. Any usage by Tenant

personal injury and property damage that may result to Tenant from theft, 
burglary or intentional conduct on the part of any person or entity except 
Landlord, Landlord's agents, and/or Landlord's employees.

    It is understood that Landlord does not warrant that any of the services
referred to above, or any other services which Landlord may supply, will be free
from interruption. Tenant acknowledges that any one or more such services may be
suspended or reduced by reason of accident or repairs, alterations or
improvements necessary to be made, by strikes or by any cause beyond the
reasonable control of Landlord, or by orders or regulations of any federal,
state, county or municipal authority. Any such interruption or suspension of
services shall never be deemed an eviction or disturbance to Tenant's use and
possession of the Premises or any part thereof, or, except as hereinafter
provided, render Landlord liable to Tenant for damages by abatement of rent, or
relieve Tenant of performance of Tenant's obligation under this Lease.  Landlord
will use its reasonable efforts in the event of a strike to secure parties not
involved in the labor dispute to provide minimum services for cleaning
restrooms, waste removal, and janitorial services.

    In the event of any interruption of any services furnished by Landlord,
Landlord shall use reasonable diligence to restore such service and, in the
event of the interruption of any such services furnished by Landlord for a
period in excess of forty-eight (48) hours, to the extent that Tenant is
prevented from using the Leased Premises in the ordinary course of its business
and actually ceases operating its business at the Leased Premises as a result
thereof, after Tenant provides notice thereof to Landlord, rent shall abate
during the period of such interruption. Tenant can cancel the lease if
interruption of services exceeds sixty (60) days.

    Tenant shall notify Landlord of any need for an increase in power usage.
Failure to do so and should an increase in usage of power by Tenant be
recognized by Landlord, it shall be deemed that the increased amount of usage
shall have been initiated the first day of occupancy of the Premises by Tenant.

    Whenever heat generating machines or equipment or lighting other than
building standard lights are used in the premises by Tenant which affect the
temperature otherwise maintained by the air conditioning system, Landlord shall
have the right to install supplementary air conditioning units in the Premises,
and the cost thereof, including the cost of installation and the cost of
operating and maintenance thereof, shall be paid by Tenant to Landlord upon
billing by Landlord. If Tenant installs lighting requiring power in excess of
that required for normal desk-top office equipment or normal copying equipment
as determined by Landlord, Tenant shall pay to Landlord upon billing for the
cost of such excess power as additional rent, together with the cost of
installing any additional risers or other facilities that may be necessary to
furnish such excess power to the Premises.

6.  TERM, COMPLETION OF IMPROVEMENTS:

    The term of this Lease shall commence and unless sooner terminated as
hereinafter provided, shall end on the dates respectively specified in Articles
1.5 and 1.6 hereof. Prior to the commencement of the term Landlord shall
complete, construct or install in the Premises the improvements to be
constructed or installed by Landlord pursuant to the provisions of Exhibit "C".
The Premises shall be deemed complete and possession delivered when Landlord has
substantially completed these improvements. "Substantial Completion" shall mean
when (i) installation of building standard improvements has occurred, (ii)
Tenant has direct access from street to the elevator 

                                       7 
<PAGE>

lobby on the floor where the Premises are located, and (iii) building 
services are ready to be furnished to the Premises.  Substantial Completion 
shall be deemed to have occurred notwithstanding a requirement to complete 
"punchlist" or similar corrective work. Landlord shall use its best efforts 
to advise Tenant of the anticipated date of completion at least 30 days prior 
to such date, but the failure to give such notice shall not constitute a 
default hereunder by Landlord. If Landlord, for any reason whatsoever, cannot 
deliver possession of the Premises to Tenant at the commencement of said 
term, as above specified, this Lease shall not be void or voidable, nor shall 
Landlord be liable to Tenant for any loss or damage resulting therefrom, but 
in that event rental shall be waived for the period between the commencement 
of said term and the time when Landlord can deliver possession. No delay in 
delivery of possession shall operate to extend the term hereof

    In the event Tenant does not occupy the space designated herein, all
interior finishing costs become due and payable by Tenant upon billing by
Landlord.

    In the event Landlord provides Tenant any concessions which may include but
not be limited to rent abated occupancy, and Tenant Improvements; Tenant
acknowledges, understands and agrees that (i) any concessions are personal to
Tenant and shall not be assigned or sublet, in whole or in part, to any assignee
or subtenant without the prior written approval of Landlord, and (ii) Landlord
has provided any concessions to Tenant in reliance upon Tenant's warranty that
Tenant shall faithfully and timely perform all terms and conditions in this
Lease. Accordingly, in the event Tenant fails, after written notice to Tenant,
to timely perform any term and condition of this Lease, including, without
limitation, the timely payment of rent, any concessions herein provided Tenant
shall be immediately due and payable as additional rent without further notice
or demand to Tenant.

7.  ACCEPTANCE:

    Tenant acknowledges that it has fully inspected the Premises, and hereby
accepts such "As Is". Tenant also acknowledges that the Premises are suitable
for the purposes for which the same are leased, in their present condition plus
the Tenant Improvements to be performed by Landlord pursuant to Exhibit "C".
Tenant further acknowledges that Landlord has made no warranties or
representations as to either the condition or the suitability of the Premises in
terms of the Use as specified in Article 1.3. This Lease is, and shall be
considered to be, the only agreement between the parties hereto and their
representatives and agents. All negotiations and oral agreements acceptable to
both parties have been merged into and are included herein. There are no other
representations or warranties between the parties and all reliance with respect
to representations is solely upon the representations and agreements contained
in this document.

8.  ASSIGNMENT OR SUBLETTING:

    Tenant shall not voluntarily or by action of law transfer, assign, sublet,
mortgage or otherwise transfer or encumber all or any part of Tenant's interest
in this Lease or in the Premises without Landlord's prior written consent (which
consent shall not be unreasonably withheld), nor shall Tenant suffer or permit
the Premises or any part thereof to be used or occupied by others except
Tenant's employees without Landlord's prior written consent. Any attempted
assignment, transfer, mortgage, encumbrance or subletting without such consent
shall be void and shall constitute a breach of this Lease. Regardless of
Landlord's consent, no subletting or assignment or other transfer shall release
Tenant of Tenant's obligation or alter the primary liability of Tenant to pay
the rent and to perform all other obligations to be performed by Tenant
hereunder.

    As a condition of obtaining Landlord's consent, Tenant shall submit to
Landlord with its request the effective date of the transfer (it must be at
least thirty (30) days after submission date), the name of the proposed assignee
or subtenant, the terms and provisions of the proposed transaction, the proposed
use, which must be consistent with the provisions of Article 1.3 hereof, a
financial statement, and a business history ("NOTICE"). Landlord shall respond
to Tenant with its approval or disapproval of the proposed subtenant within
fifteen (15) days from the date Landlord receives the Notice. If no response is
received within said fifteen (15) day period, the subtenant shall be deemed
approved.

    In addition, Tenant shall execute an agreement with Landlord agreeing to
pay to Landlord, 

                                       8 
<PAGE>

as Additional Rent, fifty percent (50%) of all monies or other consideration 
received by Tenant from its transferee in excess of the amounts owed by 
Tenant to Landlord under this Lease, which Additional Rent shall be paid to 
Landlord as and when received by Tenant.

9.  CONDUCT OF BUSINESS:

    Tenant agrees to conduct its business at all times in a first class manner
consistent with reputable business standards and practices.

10. DEFAULTS AND REMEDIES:

    10.1 DEFAULTS.  The occurrence of any one or more of the following events
shall constitute a default and breach of this Lease by Tenant;

         (A)  The failure by Tenant to make any payment of Base Rent, Additional
Rent or any other payment required to be made by Tenant hereunder, as and when 
due; or

         (B)  More than two defaults by Tenant within any one Lease Year for 
the nonpayment of rent hereunder, necessitating that Landlord, because of 
such defaults, shall have served upon Tenant within said Lease Year more than 
two written notices. This default shall be deemed a non-curable default; or

         (C)  The failure by Tenant to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Tenant,
other than Paragraph (A) above, where such failure shall continue for a period
of twenty (20) business days after written notice thereof from Landlord to
Tenant; or

         (D)  The insolvency of the Tenant or the execution by Tenant of an
assignment for the benefit of creditors; or

         (E)  The filing by or for reorganization or arrangement under any law
relating to bankruptcy or insolvency; or

         (F)  The appointment of a receiver or trustee to take possession of
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease; or

         (G)  The vacating or abandonment of the Premises for a period of three
(3) days or more without notice to Landlord, or dispossession by process of law
or otherwise.

    10.2 REMEDIES. Upon the occurrence of any event of default, Landlord shall
have the right at any time thereafter to pursue any one or more of the following
remedies with or without notice or demand. Pursuit of any of the following
remedies shall not preclude pursuit of any of the other remedies herein provided
or any other remedies provided by law, nor shall pursuit of any remedy herein
provided constitute a forfeiture or waiver of any rents due to Landlord
hereunder or of any damages accruing to Landlord by reason of the Tenant's
violation of any of the terms, conditions or covenants herein contained.

         (A)  Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may,
without prejudice to any other remedy which it may have for possession or
arrearages in rents, enter upon and take possession of the Premises and expel or
remove Tenant and any other person who may be occupying the Premises or any part
thereof, by force if necessary, without being liable for prosecution or any
claim for damages therefor. Tenant agrees to pay to Landlord on demand the
amount of all loss and damage which Landlord may suffer by reason of such
termination, whether through inability to relet the Premises on satisfactory
terms or otherwise.

         (B)  Enter upon and take possession of the Premises and expel or
remove Tenant and any other person who may be occupying the Premises, by force
if necessary, without being liable for prosecution or any claim for damages
therefor, and relet the Premises and receive the rents 

                                       9 
<PAGE>

therefrom. Tenant agrees to pay to Landlord on demand any deficiency that may 
arise by reason of such reletting.

         (C)  Enter upon the Premises, by force if necessary, without being
liable for prosecution or any claim for damages therefor, and do whatever Tenant
is obligated to do under the terms of this Lease. Tenant agrees to reimburse
Landlord on demand for expenses which Landlord may incur in effecting compliance
with Tenant's obligations under this Lease, and Tenant further agrees that
Landlord shall not be liable for any damages resulting to the Tenant from such
action.

         (D)  At its option, declare the rents for the entire remaining Term,
and other indebtedness if any, immediately due and payable without regard to
whether or not possession shall have been surrendered to or taken by Landlord,
and may commence action immediately thereupon and recover judgment therefor.

         Any rents which may be due Landlord, whether by acceleration or
otherwise, as provided herein, shall include Base Rent, and any Additional Rent
provided for herein.

         (E)  Demand payment for any rents be made by certified check,
cashier's check or money order.

damage to property occurring in or about the Premises or arising out of the
ownership, maintenance, use or occupancy thereof. Said insurance shall specify a
single occurrence policy limit of at least $1,000,000;

         (B)  All Risk property insurance, including coverage against damage

the state where the Building is located, in the amounts required by law.

    11.2 LANDLORD'S INSURANCE. Landlord shall obtain and keep in force during
the Term of this Lease fire and extended coverage on the Building. Tenant agrees
that it will not store, keep, use, or sell in or upon the Premises, gasoline and
related products, firearms, explosives or any other article which may be
prohibited by the standard form of fire insurance policy, or which will increase
Landlord's insurance cost.

    11.3 INSURANCE POLICIES. Insurance required to be obtained by Tenant
hereunder shall be in companies rated A+, AAA or better in "Best's Insurance
Guide", and licensed to do business in the state where the policy is written.
Tenant shall furnish Landlord proof of insurance policies within ten (10) days
after the execution of this Lease but not later than ten (10) days prior to
possession of the Premises. Such policies shall provide that coverage may not be
canceled or reduced without at least ten (10) days written notice first being
given to Landlord. If Tenant shall fail to procure and maintain the insurance
required hereunder, Landlord may but shall not be required to procure and
maintain the same, and any amounts paid by Landlord for such insurance shall be
Additional Rent, which shall be due and payable by Tenant on the next succeeding
date on which a Base Rent installment is due.

    11.4 WAIVER OF SUBROGATION. As long as their respective insurers so permit

representatives of the other for loss or damage

<PAGE>

to such waiving party or its property or the property of others under its 
control, where such loss or damage is insured under any insurance policy in 
force at the time of such loss or damage.

12. NO PERSONAL LIABILITY OF LANDLORD:

    "Landlord", as used in this Lease insofar as covenants or obligations on
the part of Landlord are concerned, shall be limited to mean and include only
the owner or owners at the time in question of the Premises. In the event of any
transfer of title, the Landlord named herein shall automatically be freed and
relieved from and after the date of such transfer or conveyance of all personal
liability as respects the performance of any covenants or obligations on the
part of Landlord contained in this Lease thereafter to be performed, provided
that any funds in the hands of such Landlord at the time of such transfer shall
be turned over to the grantee. Tenant shall look solely to the estate and
property of Landlord in the Property of which the Premises are a part for the
satisfaction of Tenant's remedies for collection of a judgment or other judicial
process requiring the payment of money by Landlord in the event of any default
or breach by Landlord of any of the terms, covenants and conditions of Lease to
be observed and/or performed by Landlord, and no other property or assets of
Landlord, its partners or agents shall be subject to levy, execution or other
enforcement procedure for the satisfaction of Tenant's remedies.

13. HOLD HARMLESS:

    Tenant shall indemnify, defend and hold Landlord harmless from any and all
claims, liabilities, damages and costs, including attorneys' fees, incurred by
Landlord which may arise from Tenant's use of the Premises or from the conduct
of its business or from any activity, work or things which may be permitted or
suffered by Tenant in, on or about the Premises, and shall further indemnify,
defend and hold Landlord harmless from and against any and all claims,
liabilities, damages and costs, including attorneys' fees, incurred by Landlord
which may arise from any breach or default in the performance of any obligation
on Tenant's part under this Lease or which may arise from any negligence of
Tenant or any of its agents, representatives, customers, employees or invitees.
Tenant shall indemnify, defend and hold Landlord harmless from and against any
and all liabilities, damages and costs, including attorneys' fees, which may
arise from any injury or loss incurred as a result of Landlord, its agents,
representatives or designees entering the Premises under an emergency
circumstance, such as fire or similar event, when Tenant is negligent.

14. ACCESS TO PREMISES:

    Landlord, its agents, representatives and designees shall have the right to
enter the Premises at any time to examine and inspect the same, or to make such
repairs, additions or alterations as Landlord may deem necessary or proper for
the safety, improvement or preservation thereof. Landlord shall give Tenant at
least twenty-four (24) hours notice (excepting emergencies) prior to entering
the Premises and shall make all reasonable efforts to conduct any inspections
and make any repairs after normal business hours. Landlord shall also have the
right to enter the Premises during Tenant's regular business hours, to exhibit
same to prospective purchasers, mortgagees, lessees and tenants (only six (6)
months prior to the Lease Expiration Date in the case of lessees and tenants).

15. ALTERATIONS:

    15.1 ALTERATIONS BY LANDLORD. The Building and common areas are at all
times subject to the exclusive control and management of Landlord. Without
limiting the generality of the foregoing, Landlord has the right in this
management and operation of the Building to do and perform such acts in and to
the Building in the use of good business judgment the Landlord determines to be
advisable for the more efficient and proper operation of the Building provided
such acts do not materially interfere with Tenant's ability to use the Premises,
including:

         (A)  Obstruct or close off all or any part of the Property for the
purpose of maintenance, repair or construction;

         (B)  Use any part of the Common Area for merchandising, display,
decorations, entertainment, and structures designed for retail selling or
special features or promotional activities;

                                       11 
<PAGE>

         (C)  Change area, level, location, arrangement or use of Property or
any part thereof;

         (D)  Construct other buildings, structures or improvements on the
Property and make alterations thereof, additions thereto, subtractions
therefrom, or rearrangements thereof, build additional stories on any building,
and construct additional buildings or facilities adjoining or proximate to the
Property;

         (E)  Construct multiple deck, elevated or underground parking
facilities, and expand, reduce or alter same in any manner whatsoever.

    15.2 ALTERATIONS BY TENANT.   Tenant shall not make any structural or
mechanical alterations in any portion of the Premises. Tenant shall not make any
interior alterations without first obtaining the written consent of Landlord.
All alterations, additions and improvements provided for herein shall become,
upon completion, the property of Landlord subject to the terms of this Lease;
however, if Landlord at its sole option so elects, Tenant shall promptly remove
all alterations, additions and improvements and any-other property placed in the
Premises by Tenant and Tenant shall be responsible for any damage caused by such
removal.

16. REPAIRS AND MAINTENANCE:

    16.1 LANDLORD'S OBLIGATIONS. Landlord shall keep in good order, condition
and repair the structural portions of the Building and those portions of the
Property not occupied or leased by any tenant, and all costs incurred by
Landlord in making such repairs or performing such maintenance shall be
operating expenses as defined in Article 5.4, provided that Landlord shall have
no obligation to perform any act which is the obligation of Tenant or any other
tenant in the Building. Tenant expressly waives the benefit of any statute now
or hereafter in effect which would otherwise afford Tenant the right to make
repairs at Landlord's expense.

    16.2 TENANT'S OBLIGATIONS. Tenant, at Tenant's expense, shall keep in good
order, condition and repair the Premises and every part thereof including,
without limiting the generality of the foregoing, all plumbing and sewer lines
to the point where they intersect with common lines, fixtures, interior walls
and interior surfaces of exterior walls, ceilings, windows, doors and plate
glass located within or upon the Premises, ordinary wear and tear excepted. All
repairs made by Tenant shall be at least of the same quality, design and class
as that of the original work.

         If Tenant refuses or neglects to make repairs and/or to maintain the
Premises or any part thereof in a manner reasonably satisfactory to Landlord,
Landlord shall have the right, but not the obligation, upon giving Tenant
reasonable written notice of its election to do so, to make such repairs or
perform such maintenance on behalf of and for the account of Tenant. Such work
shall be paid for by Tenant, as Additional Rent, promptly upon receipt of a bill
therefor.

    16.3 SURRENDER. On the last day of the Term hereof, or on any sooner
termination or date on which Tenant ceases to possess the Premises, Tenant shall
surrender the Premises, and the keys thereto, to Landlord in good and clean
condition, ordinary wear and tear excepted. Prior to such surrender, Tenant
shall repair any damage to the Premises occasioned by its removal of trade
fixtures, furnishings and equipment, which repair shall include the patching and
filling of holes and repair of structural damage.

17. LIENS:

    Tenant shall suffer no liens of any kind to be placed upon the Premises or
the Property. If any lien is placed upon the Premises or the Property as a
result of any work done on behalf of Tenant, or as a result of any goods or
services sold or rendered to Tenant, then Tenant shall, within ten (10) days of
the imposition of the lien, cause said lien to be removed, at Tenant's sole
expense. At any time Tenant either desires to or is required to make repairs or
alternations in accordance with this Lease, Landlord may require Tenant, at
Tenant's sole cost and expense, to obtain and provide to Landlord a lien and
completion bond (or such other applicable bond as determined by Landlord) in an
amount equal to one and one-half times the estimated cost of such improvements
to insure 

                                       12 
<PAGE>

Landlord against liability including but not limited to liability for mechanics'
and materialmen's liens and to insure completion of the work.

18. DAMAGE OR DESTRUCTION:

    If the Premises or the Building shall be damaged or destroyed by fire or
other casualty, Landlord shall have the following options:

    18.1 LEASE TERMINATION.

         (A)  If the Building or the Premises is damaged or destroyed to the
extent of fifty percent (50%) or more of its reasonable market value prior to
the time of said damage or destruction, Landlord may terminate this Lease as of
the date of the occurrence; provided, however that if the Landlord shall fail to
complete repairs or restoration to the Premises in accordance with Section 18.2
hereof within three (3) months of the date of such damage or destruction, Tenant
may elect to terminate this Lease.

         (B)  If the Building or the Premises is damaged or destroyed to the
extent of less than fifty percent (50%) of its reasonable market value prior to
the time of said damage or destruction but the Building cannot, in the sole
judgment of Landlord, be operated economically as an integral unit then Landlord
may terminate this Lease as of the date of the occurrence.

         (C)  If the Premises are damaged or destroyed within the last twenty-
four (24) months of the Term of this Lease or any extension thereof, to the
extent that Tenant cannot carry on Tenant's business, then Landlord and Tenant,
may terminate this Lease as of the date of the occurrence.

    18.2 REPAIR OR RESTORATION. If Landlord elects to repair or restore the
Premises to the same condition as existed before such damage or destruction, it
shall proceed with reasonable dispatch to perform the necessary work. However,
notwithstanding anything in this Lease to the contrary, if the cost of repair or
restoration exceeds any insurance proceeds available for such work, Landlord may
terminate this Lease unless Tenant shall, after notice of the amount of
deficiency, pay to Landlord that deficiency. Upon Landlord's election to repair
or restore the Premises, the Base Rent shall be abated until such work is
completed but Landlord shall not be liable to Tenant for any delay which arises
by reason of labor strikes, adjustments of insurance or any other cause beyond
Landlord's control, and in no event shall Landlord be liable for any loss of
profits or income. If fire or other casualty causing damage to the Premises or
other parts of the Building shall have been caused by the negligence or
misconduct of the Tenant, its agents, representatives, employees, or of any
other person entering the Premises under express or implied invitation of
Tenant, such damage shall be repaired by Landlord at the expense of Tenant
despite contrary provisions appearing in this Lease and in such event there
shall be no abatement of rent.

19. CONDEMNATION:

    If the Premises shall be taken by right of eminent domain, in whole or in
part, for public purposes or should be sold by Landlord under the threat of the
exercise of such power, then this Lease, at the option of Landlord, shall
terminate and the Rent shall be properly apportioned to the date of such taking,
and the Landlord shall receive the entire award for the lands and improvements
so taken, or the entire amount of any payment made under the threat of the
exercise of power of eminent domain, and Tenant shall have no claim for the
value of any portion of its leasehold estate so terminated except any claim to
which Tenant is solely entitled not affecting Landlord's claim. If less than a
substantial part of the Premises shall be taken, this Lease shall not terminate
but Landlord, at its sole expense, shall promptly restore and reconstruct the
Premises, provided such restoration and reconstruction shall make the same
reasonably suitable for the uses for which the Premises are leased, but in no
event shall Landlord be required to expend any amount greater than the amount
received by Landlord as compensation for the portion of the Premises taken by
the condemnor. Tenant's rental obligations during the unexpired portion of this
Lease shall be adjusted proportionately to reflect the gross leasable area
remaining in the Premises, as of the date on which the condemning authority
takes title or possession.

                                       13 
<PAGE>

20. FORCE MAJEURE:

    In the event that either party hereto shall be delayed or hindered in or
prevented from the performance of any act required hereunder by reason of
strikes, lockouts, inability to procure materials, loss of utility services,
restrictive governmental laws or regulations, riots, insurrection, war, acts of
God, or other reason of a like nature not the fault of the party delayed in
performing work or doing acts required under the terms of this Lease, then
performance of such act shall be excused for the period of delay and the period
for the performance of any such act shall be extended for a period equivalent to
the period of such delay.

21. SUCCESSION TO LANDLORD'S INTEREST:

    21.1 ATTORNMENT. Tenant shall attorn and be bound to any of Landlord's
successors under all terms, covenants and conditions of this Lease for the
balance of the remaining Term, provided said successors recognize Tenant's
rights outlined in this Lease.

    21.2 SUBORDINATION. This Lease shall be subordinate to the lien of any
mortgage or security deed or the lien resulting from any other method of
financing or refinancing now or hereafter in force against the Property, any
portion thereof, or upon any buildings hereafter placed upon the land of which
the Premises are a part, and to any and all advances to be made under such
mortgages, and all renewals, modifications, extensions, consolidations and
replacements thereof. The aforesaid provisions shall be self-operative and no
further instrument shall be required to evidence such subordination. Tenant
covenants and agrees to execute and deliver upon demand such further instrument
or instruments subordinating this Lease on the foregoing basis to the lien of
any such mortgage or mortgages as shall be desired by Landlord and any
mortgagees or proposed mortgagees.

    21.3 ESTOPPEL CERTIFICATE. Within ten (10) days after request therefor by
Landlord, or in the event that upon any sale, assignment or hypothecation of the
Premises and/or the land thereunder by Landlord an estoppel certificate shall be
required from Tenant, Tenant agrees to deliver in recordable form a certificate
to any proposed mortgagee or purchaser, or to Landlord, certifying that this
Lease is unmodified and in full force and effect (or if modified, the same is in
full force and effect as modified, and stating the modifications), that there
are no defenses or offsets thereto (or stating those claimed by Tenant) and the
dates to which Base Rent and Additional Rent have been paid.

22. SURRENDER OF PREMISES:

    22.1 At the expiration or earlier termination of this Lease, Tenant shall
surrender the Premises to Landlord broom clean and in the same condition as when
tendered by Landlord, reasonable wear and tear and insured casualty excepted.
Tenant shall promptly repair any damage to the Premises caused by the removal of
any furniture, trade fixtures or other personal property placed in the Premises.

    22.2 Should Tenant, with Landlord's written consent, hold over at the end
of the term hereof, Tenant shall become a Tenant at will and any such holding
over shall not constitute an extension of this Lease. During such holding over,
Tenant shall pay rent and other charges at 125% of the highest monthly rate
provided herein. If Tenant holds over at the end of the term hereof without
Landlord's written consent, Tenant shall pay Landlord as liquidated damages a
sum equal to 150% the rent to be paid by Tenant to Landlord for all the time
Tenant shall so retain possession of the Premises; provided that the exercise of
Landlord's rights under this clause shall not be interpreted as a grant of
permission to Tenant to continue in possession.

                                       14 
<PAGE>

23. PARKING:

    The parking areas, or designated portions thereof, shall be available for
the use of tenants of the Building and, to the extent designated by Landlord,
the employees, agents, customers and invitees of said tenants shall be subject
to the Rules, Regulations, Charges, and Rates as set forth by the Landlord from
time to time. However, Landlord may restrict to certain portions of the parking
areas parking for the Tenant and other tenants of the Building and their
employees and agents, and may designate other areas to be used at large only by
customers and invitees of the Building.

    Notwithstanding anything elsewhere herein contained, Landlord reserves the
right from time to time to make reasonable changes in, additions to and
deletions from the parking areas and the purposes to which the same may be
devoted, and the use of parking areas shall at all times be subject to such
reasonable rules and regulations as may be promulgated by Landlord provided that
Landlord shall not reduce Tenant's parking rights as described in subparagraph
below (although it may change the locations thereof).

    Notwithstanding the above, Tenant shall have rights to no less than thirty-
six (36) parking spaces in the surface parking lot adjacent to the Building for
Tenant's employees.

    Landlord, or its agents (if Landlord has delegated such privileges), shall
have the right to cause to be removed any cars of Tenant, its employees or
agents that are parked in violation hereof or in violation of Regulations of the
Building, without liability of any kind to Landlord, its agents or employees,
and Tenant agrees to hold Landlord harmless from and defend it against any and
all claims, losses, or damages asserted or arising in respect to or in
connection with the removal of any such automobiles as aforesaid. Tenant shall
from time to time upon request of Landlord supply Landlord with a list of
license plate numbers of all automobiles operated by its employees and agents
who are to have parking privileges hereunder.  Landlord may, as a part of the
regulations promulgated by Landlord, if for use of the Parking Areas, require
that Tenant cause an identification sticker issued by Landlord to be affixed to
all automobiles of Tenant and its employees or agents who are authorized to park
in the Parking Areas.

24. MISCELLANEOUS:

    24.1 PARTIAL INVALIDITY. If any term, covenant or condition of this Lease
or the application thereof to any person or circumstance shall, to any extent,
be invalid or unenforceable, the remainder of this Lease, or the application of
such term, covenant or condition to persons or circumstances other than those as
to which it is held invalid or unenforceable, shall not be affected thereby, and

their respective heirs, personal representatives, executors, successors and
assigns.

condition herein contained shall not be deemed to be a waiver of such term,
covenant or condition for any subsequent breach of the same or any other term,
covenant or condition herein contained. The subsequent acceptance of rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
by Tenant of any term, covenant or condition of this Lease, other than the
failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent. No covenant, term or condition of this Lease shall be deemed to have been
waived by Landlord, unless such waiver be in writing by Landlord.

    24.4 ACCORD AND SATISFACTION. No payment by Tenant or receipt by Landlord
of a lesser amount than the monthly rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement
or statement on any check or any letter accompanying any check or payment as
rent be deemed an accord and satisfaction, and Landlord 

                                       15 
<PAGE>

may accept such check or payment without prejudice to Landlord's right to 
recover the balance of such rent or pursue any other remedy in this Lease 
provided.

    24.5 ATTORNEY'S FEES. In the event any action is commenced for any breach
of any covenant, condition or agreement herein contained, the prevailing party
in such action shall be entitled to receive all costs incurred in such action,

    24.6 TIME IS OF THE ESSENCE. Time is of the essence of this agreement.

expense or liability for any compensation, commissions and charges claimed by
any other broker or agent with respect to this Lease or the negotiation thereof.

    24.8 NO LIGHT, AIR OR VIEW EASEMENT. Any diminution or shutting off of
light, air or view by any structure which may be erected on lands adjacent to
the Building shall in no way affect this Lease or impose any liability on
Landlord.

    24.9 ENTIRE AGREEMENT. This Lease and the Exhibits and Addenda attached
hereto and forming a part hereof, set forth all the covenants, promises,
agreements, conditions and understandings between Landlord and Tenant concerning
the Premises and there are no covenants, promises, agreements, conditions or
understandings, either oral or written, between them other than as are herein

amendment, change or addition to this Lease shall be binding upon Landlord or
Tenant unless reduced to writing and signed by them.

Lease shall be governed by the laws of the state in which the Building is 
located.

quietly have, hold and enjoy the Premises during the Term of this Lease and any
extension or renewal hereof

    24.13 COMPLIANCE WITH LAW.  Tenant shall comply with all present and future

    24.14 SUPERIOR LAW. If any provision of this Lease is ever in conflict and 
subordinate to any applicable law or regulation, either now in effect or 
hereafter adopted, said law or regulation shall control.

attached hereto and by this Article made a part hereof.

    24.16 EXECUTION OF LEASE. The submission of this Lease for examination does

1.  Renewal Option.

    Subject to the terms contained in this Renewal Option, Tenant shall have,
and is hereby granted the option (the "RENEWAL OPTION") to extend the term of
this Lease for one (1) additional period of five (5) years. The extended term
("EXTENDED TERM") shall commence upon the day immediately succeeding the date of
the expiration of the initial term of this Lease (the "EXTENDED TERM
COMMENCEMENT DATE"). The Renewal Option may only be exercised by Tenant giving
written notice thereof no later than six (6) months prior to the expiration of
the initial term. If Tenant fails to give notice of exercise of the Renewal
Option within such specified time period, Tenant's Renewal Option shall be
deemed waived and of no further force and effect.

    The right of Tenant to extends this Lease as provided for herein can be
exercised only if, at the time of such exercise and upon the commencement of the
Extended Term, (i) Tenant is not in default under this Lease beyond any
applicable grace period, and (ii) Tenant is in possession of at least fifty
percent (50%) of the Leased Premises (unless Landlord, in its sole discretion,
elects to waive either such condition). In the event that either of such
conditions are not satisfied or waived by Landlord, Tenant's Renewal Option
shall be terminated and of no further force and effect.

    If Tenant shall have elected (in accordance with and subject to the
provisions of this Renewal Option) to renew the term of this Lease, the Extended
Term shall be upon, and subject to, all of the terms, covenants and conditions
provided in this Lease except that (a) the Base Rental during the Extended Term
shall be determined in accordance with the procedure for determining Fair Market
Value (defined below) but in no event shall the annual Base Rental be less than
$12.00 per square foot of Net Rentable Area per year, (b) Tenant shall not have
the right to assign the Renewal Option to any sublessee of the Leased Premises
or assignee of the Lease, nor may any such sublessee or assignee exercise the
Renewal Option, and (c) except for any terms, covenants and conditions that are
expressly or by their nature inapplicable to the Extended Term including,
without limitation, this Renewal Option shall no longer be applicable.

    With respect to the renewal option, the applicable "Fair Market Value"
annual rental rate shall be that rate charged for space of comparable size and

Operating Expenses (exclusive of the Non-Capped Operating Expenses, as
hereinafter defined) for any calendar year in which the term of this Lease
commences by more than five percent (5%) per year on a cumulative basis,
compounded annually. For example, if Operating Expenses (exclusive of Non-Capped
Operating Expenses) during the calendar year in which the term of this Lease
commences were $100,000, the cap on Operating Expenses (exclusive of Non-Capped
Operating Expenses) for the fourth full calendar year would be $121,550.63

agreed that there shall be no cap on Non-Capped Operating Expenses, which are
hereby defined to mean all utility expenses, insurance premiums and real estate

3.1 IWL will make proposals to customers after soliciting a quotation for
    services from ITAR-TASS. IWL will treat ITAR-TASS as service provider and
    will consider the Russian services as IWL's cost in the proposals to the
    customers. IWL will submit to ITAR-TASS description of services,
    approximate start date, term, and resource requirements associated with
    proposed service. ITAR-TASS will provide approval of estimates and/or
    quotations within ten (10) working days of submittal by IWL. IWL will
    submit to ITAR-TASS all charges to customers based on associated ITAR-TASS
    services before IWL signs contract with the cusomter. After award of a
    contract, Appendix A will be amended and the additional payments added. 
    IWL will administer the customer contract and pay the amount specified in
    ITAR-TASS's proposal less payments due to IWL for ITAR-TASS's equipment
    purchases, subcontract charges and labor charges in support of the 
    ITAR-TASS communication earth station and backbone network. IWL will 
    provide ITAR-TASS with a statement of the total contract value. Labor 
    rates will be charged in accordance with Appendix C.

3.2 In the event a customer contract obtained by IWL involves the purchase or
    lease of equipment by said customer from  IWL, and ITAR-TASS is involved in
    providing communication services as part of this contract, IWL will provide
    an accounting schedule to ITAR-TASS, after IWL receives full payment from
    customer for said equipment. The accounting schedule will state the profit
    contained in the equipment sale. IWL will make payment to ITAR-TASS of XXX
    of said profit. Profit is defined as the equipment sales price less all
    associated costs which includes but is not limited to the direct equipment
    costs, bank interest, allocated general and administration costs,
    engineering costs, and project management expenses, purchasing, marketing,
    and shipping costs.

    IWL will supply this equipment at IWL's cost (as defined in 3.2) plus XXX
    profit. The equipment will be added to the list contained in appendix B and
    the monthly payment for the equipment will be adjusted for the remaining
    term.
<PAGE>

3.4  IWL Communications may make other payments on behalf of ITAR-TASS for
     miscellaneous items or training classes. These costs will be deducted each
     month from the total amount to be paid to ITAR-TASS at XXX profit above
     IWL's costs as defined in section 3.2. ITAR-TASS shall approve all such
     expenditures prior to their being incurred. IWL will provide ITAR-TASS with

     transferred to a specified account or when a check is placed in the mail to
     the designate address.

3.6  IWL Communications, Inc. will keep detailed accounts of the transactions
     under this contract. All labor charges assessed to ITAR-TASS by IWL will be
     documented by IWL time records which will reflect the individual performing
     services and the related time expended in performing those services..

3.7  ITAR-TASS will pay for all banking charges and currency conversion charges
     relating to payments to ITAR-TASS under this agreement.

3.8  In event that a customer reduces payments to IWL due to network outages, 
     if the outage is Russian circuit problems, IWL shall reduce the payment due
     under section 3.1 and 3.2 to ITAR-TASS by corresponding amount. If the 
     outage is due to a non-Russian circuit problem, payment to ITAR-TASS shall
     not be reduced.

3.9  ITAR-TASS shall provide maintenance support to those customers as noted in
     Appendix A.

3.10 In the event the balance owed IWL by ITAR-TASS exceeds the amount of
     customer contracts in-place, ITAR-TASS will agree to pay the amount
     exceeded balance directly.


4.0  OTHER TERMS AND CONDITIONS

5.0 ARBITRATION

     Any dispute arising under this Agreement between the parties hereto shall
     be submitted to, and finally and conclusively resolved, settled, and
     determined under the International Arbitration Rules (the "Rules") of the
     London court of International Arbitration ("LCIA") by a panel of three
     arbitrators appointed in accordance with the Rules. The arbitration shall
     take place in Stockholm, Sweden. Notice of such dispute must be timely
     given by serving upon the other party written notice of the complaint,
     including the specific paragraphs or subparagraphs of this Agreement
     allegedly violated and the remedy sought. The complainant must thereafter
     within thirty (30) days, or by written agreement within any longer agreed
     upon period, request arbitration.
 
     The panel of three arbitrators shall be chosen from a list of at least
     seven (7) qualified arbitrators appointed by the LCIA, all of whom must be
     familiar with general international business practices. The parties shall
     alternately strike names until three names remain, which persons shall
     serve as arbitrators. The party to strike first shall be determined by lot.
 
     The arbitration shall be conducted and governed pursuant to the Rules and
     accepted commercial practices. The award shall be accompanied by a written
     opinion setting forth the reason for the award and the facts relied upon.
 
     Arbitrators shall promptly hear the matter and shall within sixty (60) days
     from the hearing, render a decision, which decision shall be final,
     binding, and conclusive on the parties and their respective successors and
     assigns, and entitled to be enforced to the fullest extent permitted by
     law. Each party hereby agrees that any arbitration award may be enforced in
     any location where such party owns assets. Each party further acknowledges
     that this Agreement and any award rendered pursuant to it shall be governed
     by the 1958 United Nations Convention on the Recognition and Enforcement of
     Foreign Arbitral Awards. ITAR-TASS hereby waives any claims of sovereign
     immunity it may have regarding claims of IWL under this Agreement.
 
     Each party shall pay its own expenses of arbitration and the expenses of
     the arbitrators shall be equally shared provided, however, that is in the
     opinion of the arbitrators any claim for indemnification by any party
     hereunder or any defense or objection thereto by the other party was
     unreasonable, the arbitrators may assess, as part of the award, all or any
     part of the arbitration expense (including reasonable attorneys' fees and
     costs) of the other party and of the arbitrators against the party raising
     such unreasonable claim, defense or objection. Nothing herein set forth
     shall prevent the parties from settling any dispute by mutual agreement at
     any time.

    by a natural disaster, fire, explosion, transportation contingencies,
    quarantine, restriction, epidemic, natural catastrophe, war, civil
    disturbance, acts of the government of any country or of any governmental
    agency of official thereof, court order, labor dispute, third party 
    non-performance, or other causes, events, or circumstances beyond its
    reasonable control, and such non-performance shall not be a default under
    this Agreement nor a ground for termination of this Agreement as long as
    the excused party makes reasonable efforts to remedy, if and to the extent
    reasonably possible, the cause for such non-performance. Should the force
    majeure continue in effect for a period exceeding one-year and through best
    efforts of the parties this Agreement shall be terminated.

         Retrieval Service (hereinafter called "NIRS Bulletins Board").


5.  TERRITORY

    A.   Nothing in this Agreement shall be construed as conferring upon SELECT
         Partner an exclusive distributorship, dealership, franchise or
         territory for marketing the Products. A SELECT Partner may make sales
         of the Products in any of the fifty (50) United States, the District
         of Columbia and Puerto Rico (the "Authorized Area"), subject to SELECT
         Partner's ability to fulfill its obligations under this Agreement.

    B.   Due to the need to maintain high standards for support of the
         Products, Newbridge reserves the right to require SELECT Partner to
         provide such information as Newbridge requires to determine SELECT
         Partner's ability to adequately support the Products on all sales made
         outside of the United States.

    C.   Equipment shall be delivered F.O.B. Origin for all US orders placed
         direct with Newbridge and F.O.B. Point of Embarkation for all
         international orders. Shipments to locations outside of the United
         States will be accomplished through Newbridge Networks Corporation and
         Newbridge reserves the right to select the means of transportation and
         routing unless otherwise advised. SELECT Partner shall be responsible
         for all shipping charges, import and customs duties and any applicable
         taxes which may be imposed by the country of destination.

    D.   In the event that the Select Partner uncovers a sales opportunity
         outside of the Authorized Area, such sales will be handled on a 
         case-by-case basis. For all sales made outside of the United States, 
         SELECT Partner will be required to obtain product configuration 
         approval from the appropriate Newbridge System Engineer prior to 
         presenting any quotation to a customer. Such approval can be obtained
         by submitting a completed "Quote Request Form" to the appropriate 
         Newbridge Systems Engineer.  All direct international sales will 
         require the completion of an "INTERNATIONAL DIRECT PURCHASE REQUEST" 
         form (Exhibit D) and approval from the appropriate Newbridge 
         individuals. Newbridge shall have the right to approve all 
         international sales and for all such sales, at least one intelligent
         node on the customer's network must reside in the United States. 
         All sales made outside of the Authorized Area will be at prices 
         set forth in Exhibit B.

6.  REFERRAL ACCOUNTS

    A.   SELECT Partner may refer certain customers directly to Newbridge for
         the purchase of Newbridge products not available for sale through
         Newbridge's distributors. In all such cases SELECT Partner shall be
         entitled to receive a referral fee as outlined in paragraph E below.
         All referral accounts will require the completion of a "FINDERS FEE
         REQUEST" form (Exhibit E) and approval from the appropriate Newbridge
         individuals.

    B.   SELECT Partner acknowledges that each customer referred to Newbridge
         has not previously made contact with Newbridge for the purpose of
         purchasing products and that all customers referred to Newbridge must
         not be a Newbridge existing customer.

    C.   SELECT Partner shall be required to transfer complete account control,
         including the right for future product(s) sales, to Newbridge in
         exchange for payment of the referral fee.


                                       4

    D.   During the term of SELECT Partner's responsibilities hereunder, SELECT
         Partner will not sell competitive equipment or represent a competitive
         manufacturer into the account where it has received a referral fee
         from Newbridge.

    E.   Newbridge will pay to SELECT Partner a referral fee based on a
         percentage of the net revenue received during the first two years
         after the account referral date, according to the following schedule:
         (For purposes hereof, net revenue shall be the invoiced value of
         products shipped by Newbridge to the customer.)

implementation of all inter-rack cabling. Commissioning is the set of 
programming, testing and cutover activities carried out by Newbridge 
personnel on the Customer premises. The standard cutover support allocation 
included in Installation and Commissioning is dependent on the type of 
equipment being installed, as shown below:

              EXPECTED INSTALL TIME    AFTER HOURS CUTOVER SUPPORT

Small Node           XXXX                     XXXX
Single Shelf 3600    XXXX                     XXXX
Dual Shelf 3600      XXXX                     XXXX
3645; 36150 or       XXXX                     XXXX*
36170 (8- & 16-port)

*This number is average (per Peripheral shelf). The extent of after-hour 
cutover support for these products is a function of the size and complexity 
of the node configuration.

Services offered, as shown above, under the standard Installation and 
Commissioning include on-site after-hour cutover support of Customer voice 
and data circuits provided that function can be performed on the same day as 
the installation of the equipment. Any additional time or support required on 
a day other than the date of installation requires Extended Cutover Support 
(Part Number 91-0008-01).

Newbridge will only install and commission equipment that has previously been 
staged (SIAT).

<PAGE>

All installation work performed by Newbridge Networks Inc. is warranted to be 
free from workmanship defects in accordance with Newbridge installation 
specifications for a period of sixty (60) days. This warranty requires that 
the node(s) be accessible via a dial-up modem.

Pricing for Installation and Commissioning is based on a percentage of the 
equipment list price, and minimum per site charges apply, as shown below. 
Standard installations are performed between the hours of 8 a.m. and 5 p.m. 
(local time), Monday through Friday. Installations to be performed outside of 
those times will be billed at one and a half times the standard installation 
rate. Installations to be performed on Newbridge holidays will be 
accommodated on a best effort basis and will he billed at twice the standard 
installation rate.

THIS AGREEMENT is made this ______ day of_________________, 19____, between 
NEWBRIDGE NETWORKS INC., a Delaware corporation with principal offices

1.  LICENSE

1.1 All software provided to Customer shall be licensed subject to the terms 
and conditions of this Agreement and, as applicable, the terms set forth in 
the third party "shrink-wrapped" license packed with the software. Newbridge 
grants to Customer and Customer accepts a non-exclusive, non-transferable 
license to use any software and related documentation provided by Newbridge 
pursuant to this Agreement ("Licensed Software") for Customer's own internal 
use, solely in conjunction with hardware supplied or approved by Newbridge.  
In case of equipment failure, Customer may use the Licensed Software on a 
back-up system, but only for such limited time as is reasonably required to 
rectify the failure.

1.2 Customer acknowledges that Newbridge may have encoded within the Licensed 
Software an "application key", establishing the usage and functionality 
(e.g., the number of equivalent nodes and workstations or other features) of 
the software as it has been licensed to the Customer. The usage or 
functionality of such Licensed Software may be expanded only upon payment to 
Newbridge of an applicable upgrade fee. The above referenced application key 
shall be conveyed to Customer upon installation of the Licensed Software or 
upgrade.


2.  PROTECTION AND SECURITY OF LICENSED SOFTWARE

2.1 Customer acknowledges and agrees that the Licensed Software contains 
proprietary and confidential information of Newbridge and its third party 
suppliers and agrees to keep such information confidential. Customer agrees 
not to allow access to the Licensed Software except by its employees having a 
need for such access, in keeping with it's intended use as set forth herein. 
Such employees shall have been advised of the confidential and proprietary 
nature of information contained in the Licensed Software and shall have 
agreed to protect same.

2.2 All right, title and interest in and to the Licensed Software, other than 
that expressly granted to Customer herein, shall remain vested in Newbridge 
or its third party suppliers. Customer shall not, and shall not permit others 
to: copy, translate, modify, create derivative works from, reverse engineer, 
decompile, encumber or otherwise use the Licensed Software, except as is 
specifically authorized under this Agreement. All appropriate copyright and 
other proprietary notices and legends shall be retained on all Licensed 
Software supplied by Newbridge, and Customer shall maintain and reproduce 
such notices on any full or partial copies made.


3.  TERM

3.1 The license shall become effective upon delivery of the Licensed Software 
to Customer.

3.2 Newbridge may terminate this Agreement and/or any license issued 
hereunder: (a) upon written notice to Customer if any amount payable to 
Newbridge is not paid within thirty (30) days of the date on which payment is 
due; (b) if Customer becomes bankrupt, makes an assignment for the benefit of 
its creditors, or if its assets vest or become subject to the rights of any 
trustee, receiver or other administrator; (c) if bankruptcy, reorganization 
or insolvency proceedings are instituted against Customer and not dismissed 
within 15 days; or (d) if Customer breaches a material provision of this 
Agreement and such breach cannot be rectified or is not rectified within 15 
days of receipt of written notice of the breach from Newbridge.

3.3 Upon termination of any license, Customer shall return or destroy all 
copies of the respective Licensed Software. All obligations of Customer 
arising prior to termination, and those obligations relating to 
confidentiality and non-use, shall survive termination of this Agreement or 
of the license.
<PAGE>

4.  SUPPORT AND UPGRADES

Customer shall receive software support and upgrades for the Licensed 
Software only to the extent provided for in the applicable Newbridge software 
support program then currently in effect, and upon payment of any applicable 
fees.


5.  CHARGES

Upon shipment of the Licensed Software, Newbridge will invoice Customer for 
all fees, and any taxes, duties and other charges. Customer will be invoiced 
for any increased usage and functionality upon issuance by Newbridge of a new 
software application key. All amounts shall be due and payable within thirty 
(30) days of receipt of invoice. Interest may, at Newbridge's discretion, be 
charged on the balance of any overdue amount at a level not to exceed 1 1/2% 
per month (19.6% per annum) or highest rate allowed by law.


6.  INDEMNIFICATION

Newbridge shall defend and indemnify Customer in any action to the extent 
that such action is based upon a claim that the Licensed Software furnished 
by Newbridge infringes any patent, copyright, trade secret or other 
intellectual property right, provided that Customer: notifies Newbridge 
within ten (10) days of its discovery of the existence or imminence of such 
claim, gives Newbridge sole control of the litigation or settlement of the 
claim, and provides all such assistance as Newbridge may reasonably require. 
Notwithstanding the foregoing, Newbridge shall have no liability if the claim 
results from any modification or unauthorized use of the Licensed Software by 
Customer or use of the Licensed Software in combination with any software or 
equipment not supplied or expressly approved by Newbridge, in which event 
Customer shall defend and indemnify Newbridge against such claim.


7.  WARRANTIES

7.1 Newbridge warrants, for a period of 90 days from the date of shipment, 
that the Licensed Software, as originally delivered to Customer, will operate 
substantially in accordance with the functional description set out in the 
user manual supplied with the Licensed Software, when the Licensed Software 
is used in accordance with the user manual. Newbridge's sole liability and 
Customer's sole remedy for a breach of this warranty shall be Newbridge's 
good faith effort to rectify the nonconformity or, if after repeated efforts 
Newbridge is unable to rectify the non-conformity, Newbridge shall accept 
return of the Licensed Software and shall refund to Customer all amounts paid 
in respect thereof. This warranty is available only once in respect of any 
Licensed Software, and is not renewed by the payment of fees for additional 
equivalent nodes or other increased use.

7.2 NEWBRIDGE EXPRESSLY DISCLAIMS ALL OTHER WARRANTIES, WHETHER EXPRESS OR

and Lessor's assigns shall not be invalidated by any act, omission or neglect 
of Lessee and cannot be cancelled or modified without 60 days prior written 
notice to Lessor. As to each policy, Lessee shall immediately furnish to 
Lessor a certificate of insurance from the insurer, which certificate shall 
evidence the insurance coverage required by this SECTION 10 ("Valid 
Evidence"). Lessor shall have no obligation to ascertain the existence of or 
provide any insurance coverage for the Equipment or for Lessee's benefit. The 
insurance proceeds shall be the sole property of Lessor, and shall be used by 
Lessor for the repair or replacement of the Equipment, or if Lessee is in 
default under the terms of the Lease Agreement toward any payment of Lessee's 
obligations to Lessor. In the event Lessee fails to procure the insurance 
required above prior to the commencement of this Lease or if Lessee fails to 
provide valid evidence, or in the event Lessee fails to maintain the required 
insurance after the commencement date of this Lease, Lessor may, but will not 
be required to, and without notice to Lessee, purchase such insurance and add 
the cost, including customary charges or fees associated with the placement, 
maintenance or service of such insurance (collectively "Insurance Charge"), 
to the next monthly rental payment to become due hereunder. Lessor may 
terminate or allow to lapse any coverage obtained by Lessor without having 
any liability to Lessee. Lessee hereby appoints Lessor as Lessee's 
attorney-in-fact to make a claim for, receive payment of, and execute and 
endorse all documents, checks or drafts for loss, theft, damage or 
destruction to the Equipment under any property insurance.

11.  INDEMNITY.  Lessee will indemnify and defend Lessor, its affiliates, 
their officers, agents and employees, assigns, successors, heirs and personal 
representatives of Lessor against all loss, liability and expense, including, 
without limitation, all attorney's fees (including costs of a successful 
defense) from claims for negligence, tort, strict liability, bodily injury, 
including death or property damage or for any alleged violation of rights of 
others, including contract, patent, trademark, copyright or intellectual 
property rights or for any alleged violation of any law, ordinance, rule, 
regulation, decree, or otherwise arising from or in any way related to the 
Equipment, supplies, software, Lease Agreement, lease or otherwise, including,
without limitation, the ownership, operation, manufacturing, maintenance or 
services of the Equipment. This provision shall survive expiration, assignment
or termination of any lease under Lease Agreement.

12.  LOSS OR DAMAGE.  Lessee shall bear all the risks of loss of and damage 
to the Equipment from any cause and the occurrence of such loss or damage shall 
not relieve Lessee of any obligation hereunder. In the event of such loss or 
damage, Lessee shall immediately notify the Lessor in writing and, at the 
election of Lessor, shall; (a) place the same in like new condition and 
working order, certified for original manufacturer's maintenance and deliver 
to Lessor written confirmation or; (b) replace the same with like equipment 
in like new condition and working order, certified for original 
manufacturer's maintenance, free and clear of encumbrances and deliver to 
Lessor written confirmation, a bill of sale and serial number(s) conveying 
the replacement equipment to Lessor.

13.  FEES, COLLECTION EXPENSES AND LATE CHARGES.  Lessee shall also pay to 
Lessor with the first rental payment an administration fee of one hundred 
dollars ($100.00). If any amount payable herein is not paid when due, Lessor 
may elect for the Lessee to pay any or all amounts hereunder with respect to 
each overdue payment on demand; (a) any collection agency fees and expenses 
plus; (b) a late payment service fee equal to the greater of fifteen dollars 
($15.00) or ten percent (10%) of the late payment (but not to exceed $50.00), 
which is a reasonable approximation of the internal costs that Lessor will 
incur as a result of Lessee's delay in payment plus; (c) interest at a 
minimum of eighteen percent (18%) per annum (but not to exceed the highest 
rate permitted by law) ("Late Charge Rate") on such overdue payment for the 
period for which it is overdue. If Lessee fails to make any payment of any 
lease under this Lease Agreement or perform any of its other agreements in 
this Lease Agreement (including, without limitation, its agreement to provide 
insurance coverage and valid evidence as stated herein), Lessor may make such 
payment or perform such agreement and the amount of such payment and the 
expense of Lessor shall be additional rent, payable by Lessee on demand. 
Lessee shall pay to Lessor a fee of one hundred dollars ($100.00) for each 
check returned to Lessor unpaid in addition to any other fee provided for 
herein for a delinquent payment.

14.  ASSIGNMENT.  LESSEE SHALL NOT, DIRECTLY OR INDIRECTLY; (A) ASSIGN, SELL 
OR OTHERWISE DISPOSE OF ANY LEASE UNDER LEASE AGREEMENT OR ANY INTEREST THEREIN 
OR THE EQUIPMENT OR ANY PART THEREOF OR; (B) SUBLEASE, CREATE, GRANT, ASSUME OR 
ALLOW TO EXIST ANY LIEN OR OTHER CLAIM TO THE EQUIPMENT OR ANY PART HEREOF. 
Lessor, any assignee or representative of Lessor, may sell or grant a security 
interest in all or any part of Lessor's rights, obligations, title or interest 
in the Equipment and any lease under Lease Agreement or any amount payable under
this Lease Agreement or the Lease Agreement to any entity (a "Transferee") and 
in such event the transferee shall have all of the rights, powers and remedies 
of Lessor hereunder. Lessee shall execute all documentation deemed necessary by
Lessor, any assignee or transferee of Lessor for said assignment. Lessee agrees
that after written notice by Lessor of any such assignment, Lessee shall pay all
rent payable by Lessee hereunder to such assignee or transferee, and agrees to 
make all such payments of rent to such assignee or transferee whether or not any
lease under Lease Agreement or the Lease Agreement is terminated by operation of
law, any act of the parties or otherwise. Lessee will not (a) assert against any
such assignee or transferee, any claims by way of abatement, defense, setoff, 
counterclaim, recoupment or otherwise which Lessee may have, (b) look to such 
assignee or transferee to perform any of Lessor's obligations hereunder or (c) 
terminate or attempt to terminate any lease under Lease Agreement on account 
of any default by Lessor. Lessee acknowledges that any such transfer transaction
will not materially increase or change its obligations, burdens, duties or risks
under this Lease Agreement. This Lease Agreement and its leases shall inure to 
the benefit of and be binding upon the successors and assigns of the 
respective parties hereto and the heirs, executors and administrators of the 
Lessee, if an individual, always providing that nothing in this paragraph 
contained shall impair any of the provisions hereinbefore set forth 
inhibiting assignment without written approval of Lessor.

15.  DEFAULT.  Any of the following events or conditions shall constitute an 
event of default hereunder; (a) Lessee fails to pay any rental or any other 
payment hereunder when due; (b) Lessee fails to perform any covenant, in part 
or whole, herein; (c) Lessee becomes insolvent or makes an assignment for the 
benefit of creditors or ceases doing business as a going concern; (d) a 
receiver, trustee, conservator, or liquidator of Lessee is appointed with or 
without the application or approval of Lessee; (e) the filing by or against 
Lessee of a petition under the Bankruptcy Code of any Amendment thereto; or 
under any other insolvency law or laws providing for, but not limited to, the 
relief of Debtors or; (f) any representation or statement made or furnished to 
Lessor by or on behalf of Lessee which could prove to have been false, 
misleading or have a material effect on Lessee in any respect when made or 
furnished; (g) liquidate, dissolve or suspend business; (h) sell, transfer or 
otherwise dispose of all or a majority of its assets, except that Lessee may 
sell its inventory in the ordinary course of its business; (i) enter into any 
merger, consolidation or similar reorganization unless it is the surviving 
corporation; (j) transfer all or any substantial part of its operations or 
assets outside of the United States of America; or (k) without 30 days 
advance written notice to Lessor, change its name or chief place of business. 
Lessee shall at all times maintain a tangible net worth which is no less than 
the greater of 49% of its tangible net worth as of the date of the Lease 
Agreement or 49% of its highest tangible net worth thereafter. As used in this 
SECTION 15, the term "Lessee" also includes any guarantor of all of Lessee's 
obligations hereunder.

16.  REMEDIES.  If any event of default exists, Lessor, at Lessor's sole 
discretion, may, at any time, do one or more of the following in any order and 
Lessee shall perform its obligations imposed immediately thereby; (a) Lessor may
require Lessee to return any or all Equipment executed under this Lease 
Agreement within a minimum of ten (10) days; (b) Lessor or its agent may 
repossess any or all Equipment wherever found; (c) Lessor may sell any or all 
Equipment at public or private sale, with or without advertisement or 
publication, may re-lease or otherwise dispose of it or may use, hold or keep 
it; (d) Lessor may require Lessee to pay to Lessor on a date specified by 
Lessor, with respect to any or all Equipment (i) all accrued and unpaid rent, 
late charges and other amounts due under this Lease Agreement on or before such 
date specified by Lessor plus (ii) the present value, discounted in advance at 
two percent (2%) per annum, of the remaining rents through the end of the lease 
term and all other amounts payable under this Lease Agreement plus (iii) the 
anticipated market value of the Equipment as determined by Lessor ("Stipulated 
Loss Value") as liquidated damages for loss of the bargain and not as a penalty 
plus (iv) interest at the Late Charge Rate on the total of the foregoing; (e) 
Lessee shall immediately pay all costs, expenses, damages and loss of reasonable
profits incurred by Lessor because of the event of default or its actions under 
this section, including, without limitation, any collection agency and 
attorney's fees and expenses and; (f) Lessor may terminate this Lease Agreement 
and all its leases, may sue to enforce Lessee's performance of its obligation 
under this Lease Agreement and may exercise any other right or remedy then 
available to Lessor at law or in equity. Lessor is not required to take any 
legal process or give Lessee any notice before exercising any of the above 
remedies. Lessee expressly waives all rights to Lessor notice prior to 
exercising such remedies and pursue any and all legal action(s) against Lessor. 
None of the above remedies is exclusive, but each is cumulative and in addition 
to any other remedy available to Lessor. Lessor's exercise of one or more 
remedies shall not preclude its exercise of any other remedy at any time. No 
delay or failure on the part of Lessor to exercise any right hereunder shall 
operate as a waiver thereof nor as an acquiescence in any default, nor shall 
any single or partial exercise of any right preclude any other exercise 
thereof or the exercise of any other right at any future and all Lessor's 
rights and remedies contained herein shall survive the termination of Lease 
Agreement and any attached lease(s) hereto. Lessor shall not be required to 
sell, re-lease or otherwise dispose of any Equipment prior to Lessor 
enforcing any of the remedies described above. Lessor may sell or re-lease 
the Equipment in any manner it chooses, free and clear of any claims or 
rights of Lessee and without any duty to account to Lessee with respect 
thereto except, at Lessor's sole discretion, as provided below. If Lessor 
actually sells or re-leases the Equipment, Lessor, at its sole discretion, 
may elect to credit the net proceeds of any sale of the Equipment, or the net 
present value (discounted at the rate of eighteen percent (18%) per annum) of 
the rents payable under any new lease of the Equipment, against and up to 
(but not exceeding) the Stipulated Loss Value of the Equipment and any other 
amounts Lessee owes Lessor, or may elect to reimburse Lessee for and up to 
(but not exceeding) such amount after deducting the costs, expenses and 
reasonable profits described in above "(e)." Lessor may credit excess net 
proceeds against any short fall (residual position) in the lease (future 
valued at eighteen percent (18%) from the lease commencement date) before 
stated election of any reimbursement(s) to Lessee. If Lessor elects in 
writing to sell or re-lease any Equipment, it may similarly elect to credit 
or reimburse Lessee for Lessor's reasonable estimate of such Equipment's 
market value.

17.  RETURN OF EQUIPMENT.  Upon lease term expiration, at Lessee's sole expense,
Lessee shall; (a) immediately return the Equipment to Lessor, in like new 
condition, including, without limitation, certified for maintenance by the 
original manufacturer, all owner's manuals and Equipment cables, to a location 
designated by Lessor; (b) bear all expenses incurred by Lessor to bring the 
Equipment to such like new condition, as set forth and Lessee agrees to 
immediately pay Lessor for such expenses incurred upon written notice by Lessor;
(c) agree that all shortfall positions (residual position) taken in soft costs 
and the lease by Lessor, including, without limitation, (i) system software, 
(ii) application software, (iii) installation, (iv) maintenance and (v) fees, 
shall be immediately paid by Lessee, future valued at eighteen percent (18%) 
from lease rental commencement until termination of the lease, upon written 
notice by Lessor, and; (d) agree to lease finance any lease term extensions, 
and all replacement equipment with Lessor, at Lessor's sole discretion, or at 
a mutually agreed upon rate; (e) purchase Equipment. In the event Lessee elects
to purchase Equipment, Lessor will provide a market value of the Equipment for 
Lessee's option to purchase in its entirety as owner. Should Lessee not return 
or purchase the Equipment, Lessee shall continue to pay rent to Lessor as 
specified; SECTION 3.

18.  UCC FILINGS AND FINANCIAL STATEMENTS.  Lessor and Lessee agree that a 
reproduction of this Lease Agreement and its attaches may be filed as a 
financing statement and shall be sufficient as a financing statement under the 
Uniform Commercial Code. Lessee hereby ratifies all action of the Lessor in 
executing and filing financing statements prior to the execution of this Lease 
Agreement. Lessee shall execute or obtain or deliver to Lessor, upon Lessor's 
request, such other documents as Lessor deems necessary or advisable for the 
protection or perfection of this Lease Agreement and its attaches and Lessor's 
rights hereunder and shall pay all costs incident thereto. Lessee authorizes 
Lessor to insert in this Lease Agreement and its attaches, in any filings, the 
serial number(s) of all the leased Equipment, and irrevocably appoints Lessor as
Lessee's attorney-in-fact to sign any such filings. Lessee shall make available 
to the Lessor all financial statements and tax returns upon request. At a 
minimum, Lessee agrees to provide Lessor such statements during any lease term 
attached hereto.

19.  ENTIRE AGREEMENT.  THIS AGREEMENT REPRESENTS THE FINAL, COMPLETE, AND 
ENTIRE AGREEMENT BETWEEN THE PARTIES. THERE ARE NO ORAL OR WRITTEN AGREEMENTS
OR UNDERSTANDINGS AFFECTING THIS LEASE AGREEMENT, THE LEASE OR EQUIPMENT. No 
manufacturer, vendor or supplier or software manufacturer, vendor or supplier 
is the agent of Lessor. Any representation, warranty or agreement made by a 
manufacturer, vendor or supplier or software manufacturer, vendor or supplier or
their employees, sales representatives or agents shall not be binding on Lessor.
Lessee shall look solely to manufacturer, vendor or supplier or software 
manufacturer, vendor or supplier for all claims arising under its performance; 
that Lessor makes no expressed or implied warranties or representations 
whatsoever, including warranties of merchantability or fitness for a particular 
purpose, concerning said performance or the obligations thereunder, and that 
Lessee shall continue to pay Lessor all monthly rental charges and perform all 
other obligations of Lessee under this Lease Agreement without asserting any 
setoff, counterclaims, or other defense for any reason whatsoever, including 
without limitation, the failure of manufacturer, vendor or supplier or software 
manufacturer, vendor or supplier to perform its obligations; and Lessee shall 
not attempt to terminate this Lease Agreement or its leases under any condition 
or circumstance for a default or non performance by manufacturer, vendor or 
supplier or software manufacturer, vendor or supplier.

20.  MISCELLANEOUS.  In the event any provision, in part or whole, hereof shall
be invalid or unenforceable, the remaining provision(s), in part or whole, 
hereof shall remain and survive in full force and effect. The provisions of this
Lease Agreement shall be binding upon and shall inure to the benefit of the 
permitted assigns, transfers, successors, heirs and personal representatives of 
Lessor and Lessee. Lessor shall not be liable to Lessee for any direct, 
indirect, consequential, special or other damages for any reason whatsoever. If 
this Lease Agreement or any lease hereunder is signed by more than one Lessee, 
each of such Lessees shall be jointly and severally liable for payment and 
performance of all of the Lessee's obligations under this Lease Agreement. In 
the event(s) unauthorized party(s) execute signature authority or represents as 
the Lessee in action, commitment, deed or otherwise such event(s) shall be 
deemed unconditionally binding as being authorized by Lessee and Lessee herein 
as set forth; SECTION 2 shall be liable and such event(s) shall be enforceable 
by Lessor, at Lessor's sole discretion, under the terms of this Lease Agreement 
and attaches hereto unless otherwise specified by Lessor in writing.

21.  JURISDICTION.  This Lease Agreement shall be binding when accepted in 
writing by the Lessor in the State of North Carolina and shall be deemed to 
have been made in the Eastern District, North Carolina. The interpretation, 
construction and validity of this Lease Agreement shall be governed by the 
laws of the State of North Carolina, where Lessor has its principal place of 
business, where the lease is accepted and executed by Lessor, and where 
payments are to be made by Lessee unless otherwise specified by Lessor. 
Lessee hereby voluntarily consents to the jurisdiction of any Federal or 
State Court, located in the Eastern District, North Carolina with respect to 
any legal action commenced hereunder. Lessee expressly waives any right to a 
trial by jury.

22.  STATEMENT OF PURPOSE.  Lessee hereby warrants and represents that all 
leased Equipment under this Lease Agreement will be used for business 
purposes and not for personal, family or household purposes and Lessee 
acknowledges that Lessor has relied upon this representation entering into 
this Lease Agreement.

                              PROMISSORY NOTE

                            FIRST BANK AND TRUST

$1,350,000.00                 Cleveland, Texas               September 20, 1996

    For value received after date, without grace except as herein provided, in
the manner, on the date, and in the amounts herein stipulated, the undersigned,
IWL COMMUNICATIONS, INC., as principal (herein called "Maker", whether one or
more), promises to pay to the order of FIRST BANK AND TRUST, its successors and
assigns, in the City of Cleveland, Liberty County, Texas, the sum of ONE MILLION
THREE HUNDRED FIFTY THOUSAND AND NO/100 ($1,350,000.00) DOLLARS, or so much
thereof as is advanced from time to time and remains outstanding, in legal and
lawful money of the United States of America, which shall be legal tender, in
payment of all debts and dues, public and private, at the time of payment, and
to pay interest thereon, from the date hereof until maturity at the rate of nine
per cent (9%) per annum; the interest payable monthly.

    This note is due and payable as follows, to-wit:

    Interest accruing and to accrue on this note will be due and payable monthly
    on the 28th day of October and November, 1996, and thereafter this note will
    be due and payable in installments of principal in the amount of TWENTY-TWO 
    THOUSAND FIVE HUNDRED AND NO/100 ($22,500.00) DOLLARS, each plus accrued but
    unpaid interest on the 28th day of each month beginning the 28th day of 
    December, 1996, and continuing on the same date in each subsequent month 
    thereafter until the 28th day of November, 2001, at which time the entire 
    balance of this note, both principal and accrued but unpaid itnerest will 
    at once mature and become finally due and payable. All regular installments
    are to be applied first to accrued but unpaid interest and the balance, if 
    any, toward the payment of principal.

    It is also agreed that all past due principal and accrued interest shall
bear interest from the date it is due until paid at the maximum lawful rate of
interest permitted to be charged by the holder of this Note to Maker under the
laws of the State of Texas or the United States of America (whichever is higher)
and further limited by the provisions of this Note hereinafter set forth, which
provisions control the calculation of interest to be charged on the loan
evidenced by this Note (hereinafter called the "Maximum Rate"); provided,
however, nothing herein or in any instrument, document or other writing now or
hereafter securing this Note shall entitle the holder of this Note to contract
for, charge or receive interest hereon in excess of the Maximum Rate. ln the
event this Note is prepaid in full or in the event the maturity of this Note is
accelerated prior to the end of the full stated term hereof, and the interest
contracted for, charged, or received for the actual period of the existence of
this Note prior to such prepayment or acceleration exceeds the Maximum Rate, the
then holder of this Note shall credit the amount of such excess against the
amounts lawfully owing under this Note or under any instrument, document or
other writing securing this Note as of the date of such prepayment or
acceleration, in any order, preference or manner as the holder hereof may elect,
until all such sums owing to the holder hereof are fully and finally paid, and
the balance, if any, shall be refunded to the party or parties entitled thereto.

    It is, however, expressly provided and stipulated that, notwithstanding any
other provision of this Note, in no event shall the aggregate of (i) the
aggregate interest which has accrued on this Note from the date hereof through
the date of such calculation, and (ii) the aggregate of any other amounts
accrued, contracted for, charged or paid which, under applicable laws, are
deemed to constitute interest upon the loan evidenced hereby from the date
hereof through the date of such calculation, ever exceed the Maximum Rate on the
principal balance of the loan evidenced by this Note from time to time remaining
unpaid. In this connection, it is expressly stipulated and agreed that it is the
intent of the holder of this Note and the Maker in the execution and delivery of
this Note to contract in strict compliance with the state and federal usury laws
from time to time in effect. In furtherance thereof, none of the terms of this
Note or the security instruments hereinafter described shall ever be construed
to create a contract to pay for, charge, or receive for the use, forbearance or
detention of money or interest at a rate in excess of the Maximum Rate. The
Maker or any guarantors, endorsers or other parties now or hereafter becoming
liable for the Maximum Rate agree that provisions of this paragraph shall
control over all other provisions of this Note or the security instruments which
may be in apparent conflict therewith.

    Specifically and without limiting the generality of the foregoing, it is
expressly provided that:

    (i)  If under any circumstances the aggregate amounts paid, charged, or
         contracted for on this Note prior to and incident to final payment
         hereof include amounts which by law are deemed interest and which
         would exceed the Maximum Rate, the Maker stipulates that such payment
         and collection will have been and will be deemed to have been the
         result of mathematical error on the part of both Maker and the holder
         of this Note, and the party receiving such excess payments shall
         promptly refund the amount of such excess (to the extent only of such
         interest payments above the maximum amount which could lawfully have
         been collected and retained) upon discovery of such error by the party
         receiving such payment or notice thereof from the party making such
         payment; and

    (ii) All sums paid, charged, or agreed to be paid to the holder hereof for
         the use, forbearance or detention of the indebtedness evidenced hereby
         shall, to the extent permitted by applicable law, be amortized,
         prorated, allocated and spread throughout the full term of this Note.

    The principal of this Note may be prepaid in whole or in part at any time
prior to maturity provided there shall simultaneously be paid to the holder of
this Note, all interest then accrued but unpaid hereon. All prepayments shall be
applied first to accrued and unpaid interest and the balance, if any, toward
principal in inverse order of maturity.

    It is agreed that time is of the essence of this agreement, and to the
extent permitted by law, that in the event of default in the payment of any
installment of principal or interest when due for any reason, or in the event
there is or occurs any event of default under any of the terms, covenants or
provisions set forth in this Note or in any instrument, document or other
writing now or hereafter securing this Note, or in the event any maker,
endorser, surety or guarantor hereof becomes insolvent or commits an act of
bankruptcy or makes an assignment for the benefit of creditors or authorizes the
filing of or files a voluntary petition in bankruptcy or takes advantage of or
seeks any other relief under any bankruptcy, reorganization, rehabilitation,
debtor's relief or insolvency law now or hereafter existing, or in the event an
Order for Relief is instituted by or on behalf of any maker, endorser, surety or
guarantor hereof, or in the event a receiver or custodian of any property of any
maker, endorser, surety or guarantor hereof if appointed, or in the event that
any writ of garnishment, writ of sequestration, writ of attachment or other
legal process in any manner applicable to or concerning any property securing
this indebtedness of (or debt by the holder hereof to) any maker, endorser,
surety or guarantor hereof is applied for or issued, or in the event of the
occurrence or non-occurrence of any event whatsoever which would permit the
holder of this Note to accelerate the maturity hereof hereunder or under any
instrument, document or other writing now or hereafter securing or pertaining to
this Note, then in any such event, the owner and holder of this Note at its
option may declare the principal balance of this Note plus all accrued but
unpaid interest immediately due and payable, without notice of intention to
accelerate maturity or other notice, except for such notices as are applicable
and any other notices, if any, required by law, and failure to exercise said
option at any time shall not constitute a waiver of the right to exercise said
option at any other time.

    If this Note is collected by suit, through probate or bankruptcy court, or
by any other judicial proceedings, or if this Note is not paid at maturity,
howsoever such maturity may be brought about, and is placed in the hands of an
attorney for collection, then the Maker promises to pay, reasonable attorney's
fees in addition to all other amounts owing hereunder, at the time this Note is
placed in the hands of such attorney, which additional sum, to the extent
permitted by law, is agreed by Maker to be a reasonable additional liquidated
sum and which shall be immediately due and payable without notice of such event
and which shall be added to the principal of this Note and shall bear interest
at the Maximum Rate.

    To the extent permitted by law, the outstanding principal balance of this
Note plus all accrued but unpaid interest hereon shall become immediately due
and payable, at the option of the holder hereof, without presentment or demand
or any notice, except for such notices as are applicable and any other notices,
if any, required by law, to any maker, endorser, surety, guarantor or any other
person obligated hereon, whether primarily or secondarily, upon default under
the terms hereof or of any other of the above mentioned security agreements,

    of the Advances under the CAPEX Loan.

    8.2  PROMISE TO PAY INTEREST.

    Interest will be payable on demand.

         (f)  Any change in the interest rate resulting from a change in the
    Prime Rate shall take effect simultaneously with such change in the Prime
    Rate.  Interest shall be computed on the daily unpaid principal balance of
    Advances.  Interest prior to the occurrence of an Event of Default shall be
    calculated for each calendar day at 1/360th of the applicable per annum
    rate, which will result in an effective per annum rate higher than that
    specified in ITEMS 19, 19A and 19B of the Schedule, unless such calculation
    would exceed the Maximum Legal Rate, in which event interest shall be
    calculated for each calendar day at 1/365th or 1/366th, as the case may be,
    of the applicable per annum rate.  Interest subsequent to the occurrence
    of; and during the continuance of; an Event of Default shall be calculated
    for each calendar day at 1/365th or 1/366th, as the case may be, of the
    applicable per annum rate. In no event shall the rate of interest exceed
    the Maximum Legal Rate. If Debtor pays to Secured Party interest in excess
    of the Maximum Legal Rate, such excess shall be applied in reduction of the
    principal of Advances made pursuant to this Agreement, and any remaining
    excess interest, after application thereof to the principal of Advances,
    shall be refunded to Debtor.

    terms of any or all of the Transaction Documents; (ii) enforcing the
    Transaction Documents; (iii) performing, pursuant to Section 14.2, Debtor's

    relating to the Collateral (e.g., filing fees, recording taxes, and
    documentary stamp taxes); (v) maintaining the Marine Payment Account; (vi)
    administering the Transaction Documents, but not ordinary general and
    administrative expenses; (vii) compromising, pursuing, or defending any
    controversy, action, or proceeding resulting, directly or indirectly, from
    Secured Party's relationship with Debtor, regardless of whether Debtor is a
    party to such controversy, action, or proceeding and of whether the
    controversy, action, or proceeding occurs before or after the Indebtedness
    has been paid in full; (viii) realizing upon or protecting any Collateral;
    (ix) enforcing or collecting any Indebtedness or guaranty thereof; (x)
    employing collection agencies or other agents to collect any or all of the
    Receivables; (xi) examining Debtor's books and records or inspecting the
    Collateral where such examinations or inspections must be conducted, at
    Secured Party's option, more frequently than is customary, including,
    without limitation, the reasonable costs of examinations and inspections
    conducted by third parties, provided 

LOAN AGREEMENT-PAGE 22

<PAGE>

    that nothing herein shall limit Secured Party's right to audit, examination,
    inspection, or other fees otherwise payable under Section 8.3; and (xii) 
    obtaining independent appraisals from time to time as deemed necessary or 
    appropriate by Secured Party.

         (b)  Without limiting Section 8.4(a), Debtor also agrees to pay to
    Secured Party, on demand, the actual fees and disbursements incurred by
    Secured Party for attorneys retained by Secured Party for advice, suit,
    appeal, or insolvency or other proceedings under the Federal Bankruptcy
    Code or otherwise, or in connection with any purpose specified in Section
    8.4(a).

         (c)  If after the date hereof, Secured Party determines that (i) the
    adoption of any applicable law, rule, or regulation regarding capital
    requirements for banks or bank holding companies or the subsidiaries
    thereof, (ii) any change in the interpretation or administration of any
    such law, rule, or regulation by any governmental authority, central bank,
    or comparable agency charged with the interpretation or administration
    thereof; or (iii) compliance by Secured Party or its holding company with
    any request or directive of any such governmental authority, central bank
    or comparable agency regarding capital adequacy (whether or not having the
    force of law), has the effect of reducing the return on Secured Party's
    capital to a level below that which Secured Party could have achieved
    (taking into consideration Secured Party's and its holding company's
    policies with respect to capital adequacy immediately before such adoption,
    change, or compliance and assuming that Secured Party's capital was fully
    utilized prior to such adoption, change, or compliance) but for such
    adoption, change, or compliance as a consequence of Secured Party's
    commitment to make Advances pursuant hereto by any amount deemed by Secured
    Party to be material:

             (x)  Secured Party shall promptly, after Secured Party's 
        determination of such occurrence, give notice thereof to Debtor; and

             (y)  Debtor shall pay to Secured Party as an additional fee from 
        time to time, on demand, such amount as Secured Party certifies to be 
        the amount that will compensate Secured Party for such reduction.  A 
        certificate of Secured Party claiming entitlement to compensation as 
        set forth above will be conclusive in the absence of manifest error. 
        Such certificate will set forth the nature of the occurrence giving 
        rise to such compensation, the additional amount or amounts to be 
        paid to Secured Party, and the method by which such amounts were 
        determined.  In determining such amount, Secured Party may use any 
        reasonable averaging and attribution method.

    8.5. METHOD OF PAYMENT OF PRINCIPAL, INTEREST, FEES, AND COSTS 
AND EXPENSES. Without limiting Debtor's obligation, pursuant to 
Sections 8.1, 8.2, 8.3, and 8.4 to pay the principal of Advances, 
interest, fees, and costs and expenses, the following provisions 
shall apply to the payment thereof:

         Inventory, and any funds in the Marine Payment Account, to the payment 
         of such items.

         (c)  Notwithstanding any other provision of this Agreement, Secured
    Party, at its option, shall determine the manner and amount of application
    of payments and credits, if any, to be made on all or any part of any
    component or components of the Indebtedness, whether principal, interest,
    fees, costs and expenses, or otherwise.

    8.6. COMPUTATION OF DAILY OUTSTANDING BALANCE. For the purpose of 
calculating the aggregate principal balance of outstanding Advances 
under Sections 2.1(a) and (b), Section 2.5 and Section 2.6, Advances 
shall be deemed to be paid on the date that checks drawn on, or other 
funds received from, the Marine Payment Account are applied by 
Secured Party to Advances, and on the date any other payments on 
Receivables, or other payments from sales or leases of Inventory to 
be so applied, have been processed for collection by Secured Party; 
provided, however, for the purpose of calculating interest payable by 
Debtor, funds from the Marine Payment Account, payments on 
Receivables, other payments from sales or leases of Inventory, and 
any other payments, shall be deemed to be applied to Advances the 
number of days specified in ITEM 21 of the Schedule after the 
application of such funds from the Marine Payment Account or receipt 
of such payments by Secured Party, and the amount of interest payable 
will be adjusted by Secured Party from time to time accordingly. 
Notwithstanding any other provision of this Agreement, if any item 
presented for collection by Secured Party is not honored, Secured 
Party may reverse any provisional credit which has been given for the 
item and make appropriate adjustments to the amount of interest and 
principal due.

    8.7. ACCOUNT STATED.  Debtor agrees that each monthly or other 
statement of account mailed or delivered by Secured Party to Debtor 
pertaining to the outstanding balance of Advances, the amount of

conclusive, and binding on Debtor and shall constitute an "account 
stated" with respect to the matters contained therein unless, within

not mailed, delivered to Debtor, Debtor shall deliver to Secured

    8.8. MAXIMUM LEGAL RATE OF INTEREST.  No agreements, conditions, 
provisions or stipulations contained in this Agreement or in any other 
agreement between Debtor and Secured Party, or the occurrence of an Event of 
Default hereunder, or the exercise by Secured Party of the right to 
accelerate the payment of the maturity of principal and interest, or to 
exercise any option whatsoever contained in this Agreement or any other 
agreement between Debtor and Secured Party, or the arising of any contingency 
whatsoever, shall entitle Secured Party to collect, in any event, interest 
exceeding the Maximum Legal Rate; and in no event shall Debtor be obligated 
to pay interest exceeding such Maximum Legal Rate, and all agreements, 
conditions or stipulations, if any, which may in any event or contingency 
whatsoever operate to bind, obligate, or compel Debtor to pay a rate of 
interest exceeding the Maximum Legal Rate shall be without binding force or 
effect, at law or in equity, to the extent only of the excess of interest 
over such Maximum Legal Rate. In the event any interest is charged in excess 
of the Maximum Legal Rate (herein referred to as the "Excess"), Debtor 
acknowledges and stipulates that any such charge shall be the result of an 
accidental and bona fide error, and such Excess shall be, first, applied to 
reduce the principal of any Indebtedness due, and, second, returned to 
Debtor, it being the intention of the parties hereto not to enter at any time 
into a usurious or otherwise illegal relationship. The parties hereto 
recognize that with fluctuations in the Prime Rate such an unintentional 
result could inadvertently occur. By the execution of this Agreement, Debtor 
covenants that (a) the credit or return of any Excess shall constitute the 
acceptance by Debtor of such Excess, and (b) Debtor shall not seek or pursue 
any other remedy, legal or equitable against Secured Party based, in whole or 
in part, upon the charging or receiving of any interest in excess of the 
Maximum Legal Rate. For the purpose of determining whether or not any Excess 
has been contracted for, charged, or received by Secured Party, all interest 
at any time contracted for, charged, or received by Secured Party in 
connection with the Indebtedness shall be amortized, prorated, allocated and 
spread in equal parts during the entire term of this Agreement.

    8.9. ADJUSTMENTS BASED ON THE MAXIMUM LEGAL RATE OF INTEREST. 
Notwithstanding the provisions of Section 8.8 of this Agreement to the 
contrary, (a) if at any time the amount of interest computed on the basis of 
any of the fluctuating per annum rates specified in ITEMS 19, 19A, 19B, or 
19C of the Schedule (the "ANNUAL RATES") would exceed the amount of such 
interest computed upon the basis of the Maximum Legal Rate, the interest 
payable under this Agreement shall be computed upon the basis of the Maximum 
Legal Rate, but any subsequent reduction in the Annual Rates shall not reduce 
such interest thereafter payable hereunder below the amount computed on the 
basis of the Maximum Legal Rate until the aggregate amount of such interest 
accrued and payable under this Agreement equals the total amount of interest 
which would have accrued if such interest had been at all times computed 
solely on the basis of the Annual Rates; and (b) unless preempted by federal 
law, the Annual Rates from time to time in effect hereunder may not exceed 
the "Indicated Ceiling Rate" from time to time in effect under Chapter 15 of 
the Texas Credit Code (Vernon's Texas Civil Statutes), Section (c), Article 
5069-1.04, as amended.

    8.10.     INCORPORATION BY REFERENCE OF MAXIMUM LEGAL RATE OF INTEREST
PROVISIONS. The provisions of Section 8.8 of this Agreement shall be deemed to
be incorporated into every document or communication relating to the
Indebtedness which sets forth or prescribes any account, right, or claim or
alleged account, right, or claim of Secured Party with 


LOAN AGREEMENT - PAGE 25
<PAGE>

respect to Debtor (or any other obligor in respect of the Indebtedness), 
whether or not any provision of Section 8.8 of this Agreement is referred to 
therein. All such documents and communications and all figures set forth 
therein shall for the sole purpose of computing the extent of the 
Indebtedness asserted by Secured Party thereunder, be automatically 
recomputed by Debtor and Secured Party or any other obligor, and by any court 
considering the same, to give effect to the adjustments or credits required 
by Section 8.8 of this Agreement.

    8.11.     SUBSEQUENT CHANGE OF MAXIMUM LEGAL RATE OF INTEREST. If the
applicable state or federal law is amended in the future to allow a greater rate
of interest to be charged under this Agreement than is presently allowed by
applicable state or federal law, then the limitation of interest hereunder shall
be increased to the maximum rate of interest allowed by applicable state or
federal law as amended, which increase shall be effective hereunder on the
effective date of such amendment, and all interest charges owing to Secured
Party by reason thereof shall be payable upon demand.

9.  PROCEDURES AFTER SCHEDULING RECEIVABLES.

    9.1. RETURNED MERCHANDISE. Debtor shall notify Secured Party immediately of
the return, rejection, repossession, stoppage in transit, loss, damage, or
destruction of any Inventory. In addition to making appropriate adjustments to
the Receivables Borrowing Base and the Inventory Borrowing Base to reflect the
return of such Inventory, Secured Party may, in its sole discretion, request
Debtor to pay to Secured Party an amount equal to the consideration to have been
paid for such Inventory by the Account Debtor, such payment to be applied
directly to unpaid Advances.

    9.2. CREDITS AND EXTENSIONS.

         (a)  Granting of Credits and Extensions. Debtor may grant such Credits
    and such Extensions as are ordinary in the usual course of Debtor's
    business without the prior consent of Secured Party; provided, however,
    that any such Extension shall not extend the time for payment beyond thirty
    (30) days after the original due date as shown on the Invoice evidencing
    the related Receivable, or as computed based on the information set forth
    on such Invoice.

         (b)  Accounting for Credits and Extensions. Debtor shall make a full
    accounting of each grant of a Credit or an Extension, including a brief
    description of the reasons therefor and a copy of all credit memoranda.
    Such accountings shall be in form satisfactory to Secured Party and shall
    be delivered to Secured Party daily or at such other intervals as may be
    specified in ITEM 18 of the Schedule. All credit memoranda issued by Debtor
    shall be numbered consecutively and copies of the same, when delivered to
    Secured Party, shall be in numerical order and accounted for in the same
    manner as provided in Section 6.2 with respect to Invoices.

         (c)  Adjustment to Receivables Borrowing Base. The Receivables
    Borrowing Base will be reduced by the amount of all Credits reflected in an
    accounting required by 


LOAN AGREEMENT - PAGE 26
<PAGE>

    Section 9.2(b) and may, in the sole discretion of Secured Party, be 
    reduced by the full amount of any Receivables for which Extensions 
    were granted.

    9.3. RETURNED INSTRUMENTS. In the event that any check or other 
instrument received in payment of a Receivable shall be returned uncollected 
for any reason, Secured Party may, in its sole discretion, again forward the 
same for collection or return the same to Debtor. Upon receipt of a returned 
check or instrument by Debtor, Debtor shall immediately make the necessary 
entries on its books and records to reinstate the Receivable as outstanding 
and unpaid and immediately notify Secured Party of such entries. Pursuant to 
Section 1.1 (cc)(iii), the Receivable with respect to which such check or 
instrument was received shall thereupon become an Ineligible Receivable.

    9.4. DEBIT MEMORANDA.

         (a)  Unless Secured Party otherwise notifies Debtor in writing, Debtor
    shall deliver at least monthly to Secured Party, together with the
    Borrowing Base Report provided for in ITEM 18 of the Schedule, copies of
    all debit memoranda issued by Debtor.

         (b)  All debit memoranda issued by Debtor shall be numbered
    consecutively and copies of the same, when delivered to Secured Party,
    shall be in numerical order and accounted for in the same manner as
    provided in Section 6.2 with respect to Invoices.

    9.5. NOTES RECEIVABLE.  Debtor shall not accept any note or other 
instrument (except a check or other instrument for the immediate payment of 
money) with respect to any Receivable without the prior written consent of 
Secured Party. If Secured Party, at its option, consents to the acceptance of 
any such note or instrument, the same shall be considered as evidence of the 
Receivable giving rise to such note or instrument, shall be subject to the 
Security Interest, and shall not constitute payment of such Receivable, and 
Debtor shall forthwith endorse such note or instrument to the order of 
Secured Party and deliver the same to Secured Party. Upon collection, the 
proceeds of such note or instrument may be applied directly to unpaid 
Advances, interest, and costs and expenses as provided in Section 8.5.

10.  AFFIRMATIVE COVENANTS. So long as any part of the Indebtedness remains
unpaid, or this Agreement remains in effect, Debtor shall comply with the

    or any other lending agreement with Debtor shall prove to have been false
    in any material respect at the time as of which the facts therein set forth
    were certified or to have omitted any substantial contingent or
    unliquidated liability or claim against Debtor or any such Third Party, or
    if on the date of the execution of this Agreement there shall have been any

    death of Ignatius W. Leonards shall not be an Event of Default until the
    expiration of a period of 150 days immediately following his death, so long

    for a new President with credentials comparable to those of Ignatius W.
    Leonards.

         (p)  Change of Ownership. If all, or a controlling interest of; the
    capital stock of Debtor shall be sold, assigned, or otherwise transferred

12.2.    EFFECTS OF AN EVENT OF DEFAULT.

    (a)  Upon the happening of one or more Events of Default (except an Event
of Default under either Section 12.1(e) or 12.1(f), Secured Party may declare
any obligations it may have hereunder to be canceled, and the principal of the
Indebtedness then outstanding to be immediately due and payable, together with
all interest thereon and costs and expenses accruing under the Transaction
Documents.  Upon such declaration, any obligations Secured Party may have
hereunder shall be immediately canceled, and the 


LOAN AGREEMENT - PAGE 37

<PAGE>

    Indebtedness then outstanding shall become immediately due and payable 
    without presentation, demand, or further notice of any kind to Debtor.

        (b)  Upon the happening of one or more Events of Default under Section 
    12.1(e) or 12.1(f), Secured Party's obligations hereunder shall be canceled
    immediately, automatically, and without notice, and the Indebtedness then
    outstanding shall become immediately due and payable without presentation,
    demand, or notice of any kind to the Debtor.

13. SECURED PARTY'S RIGHTS AND REMEDIES.

    13.1.     GENERALLY. Secured Party's rights and remedies with respect to
the Collateral, in addition to those rights granted herein and in any other
agreement between Debtor and Secured Party now or hereafter in effect, shall be
those of a secured party under the Uniform Commercial Code as in effect in the
State and under any other applicable law.

    13.2.     NOTIFICATION OF ACCOUNT DEBTORS. Upon the occurrence of an Event
of Default or an event which with notice or lapse of time, or both, would
constitute an Event of Default, Secured Party may, at any time and from time to
time, notify any or all Account Debtors of the Security Interest and may direct
such Account Debtors to make all payments on Receivables directly to Secured
Party.

    13.3.     POSSESSION OF COLLATERAL. Whenever Secured Party may take
possession of the Collateral, pursuant to Section 13.1, Secured Party may take
possession of the Collateral on Debtor's premises or may remove the Collateral,
or any part thereof; to such other places as the Secured Party may, in its sole
discretion, determine. If requested by Secured Party, Debtor shall assemble the
Collateral and deliver it to Secured Party at such place as may be designated by
Secured Party.

    13.4.     COLLECTION OF RECEIVABLES. Upon the occurrence of an Event of
Default or an event which with notice or lapse of time, or both, would
constitute an Event of Default, Secured Party may demand, collect, and sue for
all monies and Proceeds due, or to become due, on the Receivables (in either
Debtor's or Secured Party's name at the latter's option) with the right to
enforce, compromise, settle, or discharge any or all Receivables. If Secured
Party takes any action contemplated by this Section with respect to any
Receivable, Debtor shall not exercise any right that Debtor would otherwise have
had to take such action with respect to such Receivable.

    13.5.     ENDORSEMENT OF CHECKS; DEBTOR'S MAIL. Debtor hereby irrevocably
appoints Secured Party the Debtor's agent with full power, in the same manner,
to the same extent, and with the same effect as if Debtor were to do the same:
upon the occurrence of an Event of Default or an event of which with notice or
lapse of time, or both, would constitute an Event of Default, to endorse
Debtor's name on any Instruments or Documents pertaining to any Collateral, to
receive and collect all mail addressed to Debtor, to direct the place of
delivery of such mail to any location designated by Secured Party, to open such
mail, to remove all contents therefrom, and to retain all contents thereof
constituting or relating to the Collateral. This agency is unconditional


LOAN AGREEMENT - PAGE 38
<PAGE>


and shall not terminate until all of the Indebtedness is paid in full and 
this Agreement has been terminated. Secured Party agrees to give Debtor 
notice in the event it exercises this agency, except with respect to the 
endorsement of Debtor's name on any instruments or documents pertaining to 
any Collateral.

    13.6.     LICENSE TO USE PATENTS, TRADEMARKS, AND TRADENAMES. Debtor grants
to Secured Party a royalty-free license to use any and all patents, trademarks,
and tradenames now or hereafter owned by, or licensed to, Debtor for the
purposes of manufacturing and disposing of Inventory after the occurrence of an
Event of Default. All Inventory shall at least meet quality standards maintained
by Debtor prior to such Event of Default.

14. MISCELLANEOUS.

    14.1.     PERFECTING THE SECURITY INTEREST; PROTECTING THE COLLATERAL. 
Debtor will execute and deliver to Secured Party such financing statements,
assignments, and other documents and will do such other things in connection
with the Transaction Documents as Secured Party may request. Debtor hereby
authorizes Secured Party to file such financing statements relating to the
Collateral without Debtor's signature thereon as Secured Party may deem
appropriate, and appoints Secured Party as Debtor's attorney-in-fact (without
requiring Secured Party) to execute any such financing statement or statements
in Debtor's name and to perform all other acts which Secured Party deems
appropriate to perfect and continue the Security Interest and to protect,
preserve, and realize upon the Collateral.

    14.2.     PERFORMANCE OF DEBTOR'S DUTIES. Upon Debtor's failure to 
perform any of its duties under the Transaction Documents, including, without 
limitation, the duty to obtain insurance as specified in Section 10.11, 
Secured Party may, but shall not be obligated to, perform any or all such 
duties.

    14.3.     NOTICE OF SALE.  Without in any way requiring notice to be given
in the following manner, Debtor agrees that any notice by Secured Party of sale,
disposition, or other intended action hereunder, or in connection herewith,
whether required by the Uniform Commercial Code as in effect in the State or
otherwise, shall constitute reasonable notice to Debtor if such notice is mailed
by regular or certified mail, postage prepaid, at least five (5) days prior to
such action, to Debtor's address or addresses specified above or to any other
address which Debtor has specified in writing to Secured Party as the address to
which notices hereunder shall be given to Debtor.

    14.4.     WAIVER BY SECURED PARTY.  No course of dealing between Debtor and
Secured Party and no delay or omission by Secured Party in exercising any right
or remedy under the Transaction Documents or with respect to any Indebtedness
shall operate as a waiver thereof or of any other right or remedy, and no single
or partial exercise thereof shall preclude any other or further exercise thereof
or the exercise of any other right or remedy. All rights and remedies of Secured
Party are cumulative.


LOAN AGREEMENT - PAGE 39
<PAGE>

    14.5.     WAIVER BY DEBTOR.  Secured Party shall have no obligation to 
take, and Debtor shall have the sole responsibility for taking, any and all 
steps to preserve rights against any and all Account Debtors and against any 
and all prior parties to any note, Chattel Paper, draft trade acceptance, or 
other instrument for the payment of money covered by the Security Interest 
whether or not in Secured Party's possession. Secured Party shall not be 
responsible to Debtor for loss or damage resulting from Secured Party's 
failure to enforce any Receivables or to collect any moneys due, or to become 
due, thereunder or other Proceeds constituting Collateral hereunder. Debtor 
waives protest of any note, check, draft, trade acceptance, or other 
instrument for the payment of money constituting Collateral at any time held 
by Secured Party on which Debtor is in any way liable and waives notice of 
any other action taken by Secured Party, including, without limitation, 
notice of Secured Party's intent to accelerate the Indebtedness or any part 
thereof.

    14.6.     SETOFF.  Without limiting any other right of Secured Party,
whenever Secured Party has the right to declare any Indebtedness to be
immediately due and payable (whether or not it has so declared), Secured Party,
at its sole election, may setoff against the Indebtedness any and all monies
then or thereafter owed to Debtor by Secured Party in any capacity, whether or
not the Indebtedness or the obligation to pay such monies owed by Secured Party
is then due, and Secured Party shall be deemed to have exercised such right of
setoff immediately at the time of such election even though any charge therefor
is made or entered on Secured Party's records subsequent thereto.

    14.7.     ASSIGNMENT.  The rights and benefits of Secured Party hereunder 
shall, if Secured Party so agrees, inure to any party acquiring any interest 
in the Indebtedness or any part thereof.

    14.8.     SUCCESSORS AND ASSIGNS. Secured Party and Debtor, as used 
herein, shall include the successors or assigns of those parties, except that 
Debtor shall not have the right to assign its rights hereunder or any 
interest herein.

    14.9.     MODIFICATION. No modification, rescission, waiver, release, or 
amendment of any provision of this Agreement shall be made, except as may be 
provided in Item 36 of the Schedule or by a written agreement signed by 
Debtor and a duly authorized officer of Secured Party.

    14.10.    COUNTERPARTS.  This Agreement may be executed in any number of 
counterparts, and by Secured Party and Debtor on separate counterparts, each 
of which, when so executed and delivered, shall be an original, but all of 
which shall together constitute one in the same Agreement

    14.11. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES.  Any financial calculation
to be made, all financial statements and other financial information to be
provided, and all books and records to be kept in connection with the provisions
of this Agreement, shall be in accordance with generally accepted accounting
principles consistently applied during each interval and from interval to
interval; provided, however, that in the event changes in generally accepted
accounting principles shall be mandated by the Financial Accounting Standards
Board or any


LOAN AGREEMENT - PAGE 40
<PAGE>

similar accounting body of comparable standing, or should be recommended by 
Debtor's certified public accountants, to the extent such changes would 
affect any financial calculations to be made in connection herewith, such 
changes shall be implemented in making such calculations only from and after 
such date as Debtor and Secured Party shall have amended this Agreement to 
the extent necessary to reflect such changes in the financial and other 
covenants to which such calculations relate.

    14.12. INDEMNIFICATION.

         (a)  If after receipt of any payment of all, or any part of; the
    Indebtedness, Secured Party is, for any reason, compelled to surrender such
    payment to any person or entity because such payment is determined to be
    void or voidable as a preference, an impermissible set-off, or a diversion
    of trust funds, or for any other reason, the Transaction Documents shall
    continue in full force and Debtor shall be liable, and shall indemnify and
    hold Secured Party harmless for, the amount of such payment surrendered.
    The provisions of this Section shall be and remain effective
    notwithstanding any contrary action which may have been taken by Secured
    Party in reliance upon such payment, and any such contrary action so taken
    shall be without prejudice to Secured Party's rights under the Transaction
    Documents and shall be deemed to have been conditioned upon such payment
    having become final and irrevocable. The provisions of this Section
    14.12(a) shall survive the termination of this Agreement and the
    Transaction Documents.

         (b)  Debtor agrees to indemnify, defend, and hold harmless Secured
    Party from, and against, any and all liabilities, claims, damages,
    penalties, expenditures, losses, or charges, including, but not limited to,
    all costs of investigation, monitoring, legal representations, remedial
    response, removal, restoration, or permit acquisition, which may now, or in
    the future, be undertaken, suffered, paid, awarded, assessed, or otherwise
    incurred by Secured Party or any other person or entity as a result of the
    presence of, Release of, or threatened Release of Hazardous Substances on,
    in, under, or near the property owned, leased, or operated by Debtor or any
    Consolidated Subsidiary.  The liability of Debtor under the covenants of
    this Section 14.12(b) is not limited by any exculpatory provisions in this
    Agreement or any other documents securing the Indebtedness and shall
    survive repayment of the Indebtedness or any transfer or termination of
    this Agreement regardless of the means of such transfer or termination. 
    Debtor agrees that Secured Party shall not be liable in any way for the
    completeness or accuracy of any Environmental Report or the information
    contained therein.  Debtor further agrees that Secured Party has no duty to
    warn Debtor or any other person or entity about any actual or potential
    environmental contamination or other problem that may have become apparent,
    or will become apparent, to Secured Party.

         (c)  Debtor agrees to pay, indemnify, and hold Secured Party harmless
    from, and against, any and all liabilities, obligations, losses, damages,
    penalties, actions, judgments, suits, costs, expenses, or disbursements of
    any kind or nature whatsoever (including, without limitation, counsel and
    special counsel fees and disbursements in connection with any litigation,
    investigation, hearing, or other proceeding) with respect, or in any way


LOAN AGREEMENT - PAGE 41
<PAGE>

    related, to the existence, execution, delivery, enforcement, performance,
    and administration of this Agreement and any other Transaction Document
    (all of the foregoing, collectively, the "Indemnified Liabilities").  The
    agreements in this Section 14.12(c) shall survive repayment of the
    Indebtedness.

14.13. TERMINATION; PREPAYMENT PREMIUM.

         (a)  Termination. This Agreement is, and is intended to be, a
    continuing Agreement and shall remain in full force and effect for an
    initial term equal to the term set forth in ITEM 33 of the Schedule and for
    any renewal term also specified in ITEM 33 of the Schedule; provided,
    however, that either party may terminate this Agreement as of the end of
    the initial term or any subsequent renewal term by giving the other party
    notice to terminate in writing at least sixty (60) days prior to the end of
    any such period whereupon at the end of such period all Indebtedness shall
    be due and payable in full without presentation, demand, or further notice
    of any kind, whether or not all or any part of such Indebtedness is
    otherwise due and payable pursuant to the agreement or instrument
    evidencing same. Secured Party may terminate this Agreement immediately and
    without notice upon the occurrence of an Event of Default.  Notwithstanding
    the foregoing or anything in this Agreement or elsewhere to the contrary,
    the Security Interest, Secured Party's rights and remedies under the
    Transaction Documents and Debtor's obligations and liabilities under the
    Transaction Documents, shall survive any termination of this Agreement and
    shall remain in full force and effect until all of the Indebtedness
    outstanding, or contracted or committed for (whether or not outstanding),
    before the receipt of such notice by Secured Party, and any extensions or
    renewals thereof (whether made before or after receipt of such notice),
    together with interest accruing thereon after such notice, shall be finally
    and irrevocably paid in full. No Collateral shall be released or financing
    statement terminated until: (i) such final and irrevocable payment in full
    of the Indebtedness as described in the preceding sentence; and (ii) Debtor
    and Secured Party execute a mutual general release, in form and substance
    satisfactory to the Secured Party and Debtor and their counsel.

         (b)  Revolving Credit Prepayment Premium.  If Debtor pays in full all,
    or substantially all, of the principal balance of Advances under the
    Revolving Credit prior to the end of the initial term or any renewal term
    of this Agreement as set forth in ITEM 33 of the Schedule, other than
    temporarily from funds internally generated in the ordinary course of
    business, at the time of any such payment, Debtor shall also pay to Secured
    Party the prepayment premium set forth in ITEM 35 of the Schedule.  Any
    tender of payment in full of such principal balance following an
    acceleration by Secured Party of the Indebtedness, pursuant to Section 12.2
    shall be, for purposes of this Section 14.13(b), deemed to be considered a
    prepayment requiring Debtor to pay the prepayment premium set forth in ITEM
    35 of the Schedule.

    14.14.    FURTHER ASSURANCES. From time to time, Debtor shall take such
action and execute and deliver to Secured Party such additional documents,
instruments, certificates, and 


LOAN AGREEMENT - PAGE 42
<PAGE>

agreements as Secured Party may reasonably request to effectuate the purposes 
of the Transaction Documents.

    14.15.    HEADINGS.  Article and Section headings used in this Agreement
are for convenience only and shall not affect the construction of this
Agreement.

    14.16.    CUMULATIVE SECURITY INTEREST, ETC. The execution and delivery of
this Agreement shall in no manner impair or affect any other security (by
endorsement or otherwise) for payment or performance of the Indebtedness, and no
security taken hereafter as security for payment or performance of the
Indebtedness shall impair in any manner or affect this Agreement, or the
security interest granted hereby, all such present and future additional
security to be considered as cumulative security.

    14.17.    SECURED PARTY'S DUTIES.  Without limiting any other provision of
this Agreement: (a) the powers conferred on Secured Party hereunder are solely
to protect its interests and shall not impose any duty to exercise any such
powers; and (b) except as may be required by applicable law, Secured Party shall
not have any duty as to any Collateral or as to the taking of any necessary
steps to preserve rights against any parties or any other rights pertaining to
any Collateral.

    14.18.    NOTICES GENERALLY. All notices and other communications hereunder
shall be made by telegram, telex, electronic transmitter, overnight air courier,
or certified or registered mail, return receipt requested, and shall be deemed
to be received by the party to whom sent one Business Day after sending, if sent
by telegram, telex, electronic transmitter, or overnight air courier, and three
Business Days after mailing, if sent by certified or registered mail. All such
notices and other communications to a party hereto shall be addressed to such
party at the address set forth on the cover page hereof or to such other address
as such party may designate for itself in a notice to the other party given in
accordance with this Section 14.18.

    14.19.    SEVERABILITY.  The provisions of this Agreement are independent
of, and separable from, each other, and no such provision shall be affected or
rendered invalid or unenforceable by virtue of the fact that for any reason any
other such provision may be invalid or unenforceable in whole or in part.  If
any provision of this Agreement is prohibited or unenforceable in any
jurisdiction, such provision shall be ineffective in such jurisdiction only to
the extent of such prohibition or unenforceability, and such prohibition or
unenforceability shall not invalidate the balance of such provision to the
extent it is not prohibited or unenforceable nor render prohibited or
unenforceable such provision in any other jurisdiction.

    14.20.    INCONSISTENT PROVISIONS.  The terms of this Agreement and the
other Transaction Documents shall be cumulative except to the extent that they
are specifically inconsistent with each other, in which case the terms of this
Agreement shall prevail.

    14.21.    ENTIRE AGREEMENT. This Agreement and the other Transaction

                                      TERM NOTE

$950,000.00                                                   December 20, 1995

    FOR VALUE RECEIVED, the undersigned ("BORROWER"), hereby promises to pay 
to the order of MARINE MIDLAND BUSINESS LOANS, INC., a Delaware corporation 
("LENDER"), in such coin or currency of the United States which shall be 
legal tender in payment of all debts and dues, public and private, at the 
time of payment, the principal sum of Nine Hundred Fifty Thousand Dollars and 
No/l00 ($950,000.00), together with interest on the unpaid principal balance 
outstanding from and after the date hereof (i) until maturity (whether by 
acceleration or otherwise) at a variable rate per annum equal to 
three-fourths percent (0.75%) above the Prime Rate and (ii) thereafter, at a 
variable rate per annum equal to three and three-fourths percent (3.75%) 
above the Prime Rate.

    This Term Note (the "NOTE") is the Term Note referred to in, and is 
issued pursuant to, that certain Loan and Security Agreement between Borrower 
and Lender dated December ____, 1995 (as amended from time to time, the "LOAN 
AGREEMENT"), and is entitled to all of the benefits and security of the Loan 
Agreement. All of the terms, covenants and conditions of the Loan Agreement 
and all other instruments evidencing or securing the indebtedness hereunder 
(including, without limitation, the "Transaction Documents" as defined in the 
Loan Agreement) are hereby made a part of this Note and are deemed 
incorporated herein in full. All capitalized terms used herein, unless 
otherwise specifically defined in this Note, shall have the meanings ascribed 
to them in the Loan Agreement.

    Borrower acknowledges and understands that the Prime Rate merely serves 
as a basis upon which effective rates of interest are calculated for loans 
making reference to the per annum rate of interest publicly announced by 
Marine Midland Bank from time to time as its prime rate and that such rate 
may not be the lowest or best rate at which such bank calculates interest or 
extends credit. After the date hereof, the rate of interest in effect 
hereunder shall be increased or decreased, as the case may be, by an amount 
equal to any increase or decrease in the Prime Rate, with such adjustments to 
be effective as of the opening of business on the date that any such change 
in the Prime Rate becomes effective. The Prime Rate in effect on the date 
hereof shall be the Prime Rate effective as of the opening of business on the 
date hereof, but if this Note is executed on a day that is not a Business 
Day, the Prime Rate in effect on the date hereof shall be the Prime Rate 
effective as of the opening of business on the last Business Day immediately 
preceding the date hereof.

    In no contingency or event whatsoever, whether by reason of advancement 
of the proceeds hereof or otherwise, shall the amount paid or agreed to be 
paid to Lender for the use, forbearance or detention of money advanced 
hereunder exceed the highest lawful rate permissible under any law which a 
court of competent jurisdiction may deem applicable hereto. In the event that 
such a court determines that Lender has charged or received interest 
hereunder in excess of the highest applicable rate, such rate shall 
automatically be reduced to the maximum 

TERM NOTE-PAGE 1

<PAGE>

rate permitted by applicable law and Lender shall promptly refund to Borrower 
any interest received by Lender in excess of the maximum lawful rate or, if 
so requested by Borrower, shall apply such excess to the principal balance of 
this Note. It is the intent hereof that Borrower not pay or contract to pay, 
and that Lender not receive or contract to receive, directly or indirectly in 
any manner whatsoever, interest in excess of that which may be paid by 
Borrower under applicable law.

    For so long as no Event of Default shall have occurred under the Loan 
Agreement, the principal amount and accrued interest of this Note shall be 
due and payable on the dates and in the manner hereinafter set forth:

         (a)  interest shall be due and payable monthly, in arrears, on the
    first day of each month, commencing on February 1, 1996, and continuing
    until such time as the full principal balance, together with all other
    amounts owing hereunder, shall have been paid in full;

         (b)  commencing on February 1, 1996, and continuing on the first day
    of each month thereafter to and including the first day of the month
    immediately preceding the expiration of the Renewal Term (as set forth in
    the Schedule to the Loan Agreement, including any extensions there),
    principal payments in the amount of Fifteen Thousand Eight Hundred Thirty-
    Three Dollars and No/100 ($15,833.00) each; and

         (c)  at the expiration of the Renewal Term (which presently is 
    December 31, 1998), a final principal payment equal to the entire 
    unpaid principal balance hereof, together with any and all other 
    amounts due hereunder.

    If the Renewal Term is extended in a manner as provided by the Loan 
Agreement, then the final principal payment will be due upon the expiration 
of the extended Renewal Term; and monthly principal payments, as contemplated 
in clause (b) above, shall continue to be payable during the period of any 
such extension.

    Notwithstanding the foregoing, the entire unpaid principal balance and 
accrued interest on this Note shall be due and payable immediately upon any 
termination of the Loan Agreement pursuant to Section 14.13 thereof.

    This Note shall be subject to mandatory prepayment in accordance with the 
provisions of Section 14.13 of the Loan Agreement. Borrower may prepay this 
Note in whole at any time or in part from time to time, subject to the 
applicable prepayment premium set forth in the Schedule.

    All partial prepayments, whether mandatory or voluntary, shall be applied 
to installments of principal in the inverse order of their maturities.

    The occurrence of an Event of Default under the Loan Agreement, 
including, without limitation, (i) the failure to pay any installment of 
principal or interest on this Note in full on the due date thereof in 
accordance with the terms of this Note or (ii) the failure to pay any 


TERM NOTE-PAGE 2

<PAGE>

installment of principal or interest on the CAPEX Term Note (as such term is 
defined in the Loan Agreement) in full on the due date thereof in accordance 
with the terms of the CAPEX Term Note, shall constitute an Event of Default 
under this Note and shall entitle Lender, at its option, upon, or at any time 
after the occurrence of any such Event of Default, to declare the then 
outstanding principal balance and accrued interest hereof to be, and the same 
shall thereupon become, immediately due and payable without notice to or 
demand upon Borrower, all of which Borrower hereby expressly waives. If this 
Note is collected by or through an attorney at law, then Borrower shall be 
obligated to pay, in addition to the principal balance and accrued interest 
hereof, reasonable attorney's fees, not to exceed 15% of such principal and 
interest, and court costs.

    Time is of the essence of this Note. To the fullest extent permitted by 
applicable law, Borrower, for itself and its legal representatives, 
successors and assigns, expressly waives presentment, demand, protest, notice 
of dishonor, notice of nonpayment, notice of maturity, notice of protest, 
presentment for the purpose of accelerating maturity, diligence in 
collection, and the benefit of any exemption or insolvency laws.

    Wherever possible each provision of this Note shall be interpreted in 
such a manner as to be effective and valid under applicable law, but if any 
provision of this Note shall be prohibited or invalid under applicable law, 
such provision shall be ineffective to the extent of such prohibition or 
invalidity without invalidating the remainder of such provision or remaining 
provisions of this Note. No delay or failure on the part of Lender in the 
exercise of any right or remedy hereunder shall operate as a waiver thereof, 
nor as an acquiescence in any default, nor shall any single or partial 
exercise by Lender of any right or remedy preclude any other right or remedy. 
Lender, at its option, may enforce its rights against any collateral securing 
this Note without enforcing its rights against Borrower, any guarantor of the 
indebtedness evidenced hereby or any other property or indebtedness due or to 
become due to Borrower. Borrower agrees that, without releasing or impairing 
Borrower's liability hereunder, Lender may at any time release, surrender, 
substitute or exchange any collateral securing this Note and may at any time 
release any party primarily or secondarily liable for the indebtedness 
evidenced by this Note.

    This Note shall be governed by, and construed and enforced in accordance 
with, the internal laws of the State of Texas.

    IN WITNESS WHEREOF, Borrower has caused this Note to be duly executed 
and delivered in Dallas, Texas, on the date first above written.

If any payment obligation under this Note is not paid when due, the Promisor 
promises to pay all costs of collection, including reasonable attorney fees, 
whether or not a lawsuit is commenced as part of the collection process.

If any of the following events of default occur, this Note and any other 
obligations of the Promisor to the Payee, shall become due immediately, 
without demand or notice:

in full on or before the Due Date;

2)  the filing of bankruptcy proceedings involving the Promisor as a Debtor;

3)  the application for appointment of a receiver for the Promisor;

4)  the making of a general assignment for the benefit of the Promisor's 
creditors;

5)  the insolvency of the Promisor; or

6)  the misrepresentation by the Promisor to the Payee for the purpose of 
obtaining or extending credit.

In addition, the Promisor shall be in default if there is a sale, transfer, 
assignment, or any other disposition of any assets pledged as security for 
the payment of this Note, or if there is a default in any security agreement 
which secures this Note.

If any one or more of the provisions of this Note are determined to be 
unenforceable, in whole or in part, for any reason, the remaining provisions 
shall remain fully operative.
