ITEM 1 - BUSINESS

THE COMPANY

        STM Wireless, Inc. (the "Company" or "STM"), is a developer,
manufacturer and provider of wireless-based satellite communications
infrastructure and user terminal products utilized in public and private
telecommunications networks. These networks support data, fax, voice and video
communication and are used to either bypass or extend terrestrial networks or
provide a communications infrastructure where a network does not currently
exist. The Company's product line is based on proprietary hardware and software
and primarily consists of two-way earth stations, sometimes referred to as VSATs
(very small aperture terminals), associated infrastructure equipment and
software, transceivers, modems and other networking equipment. The Company
currently focuses its sales efforts on the international marketplace,
particularly developing countries because management believes that these areas
offer greater applications for the Company's technology, a higher growth
potential and more favorable competitive dynamics. The Company's proprietary
equipment and software are utilized by businesses, government agencies and
telephone companies in Europe, the Americas, Africa and Asia.

        The Company was incorporated in California in January 1982 as Services
Via Satellite and in December 1982 changed its name to Satellite Technology
Management, Inc. In January 1995, the Company registered in California to do
business as STM Wireless, Inc. In December 1995, the Company reorganized as a
Delaware corporation via a merger into a wholly-owned subsidiary with the name
STM Wireless, Inc.

RECENT EVENTS

        Direc-To-Phone International, Inc.: As part of STM's goal to expand its
role as a leading provider of fixed telephony solutions, the Company formed
Direc-To-Phone International, Inc. ("DTPI") in September 1996. Utilizing
equipment manufactured by STM and others, DTPI, through joint ventures and
partnership agreements with local telecommunication service providers, provides
rural telephony services in developing countries. DTPI seeks to achieve
international market penetration for its products and services through the
establishment of in-country joint venture relationships. DTPI and its joint
venture partners are responsible for their pro rata share of the cost of any
investment. DTPI contributes technology, know-how and expertise while the local
partners maintain the operating licenses, and provide frontline customer
service. In the second half of 1997, DTPI was awarded two major contracts for
rural telephony services in Mexico and Venezuela.

        In Mexico, DTPI has partnered with a newly created entity, a joint
venture between Korea Telecom and a local Mexican partner, formed to hold and
operate telecommunications licenses in Mexico (the "Mexican Telecom Venture"),
to build and operate a nationwide telephony network. The Mexican Telecom Venture
has guaranteed DTPI a minimum revenue stream of approximately $103 million over
the ten-year term of the contract.

        In Venezuela, DTPI is in the process of forming a joint venture ("JV")
with Compania Anonima Telefonos de Venezuela ("CANTV"), the Venezuelan national
telephone company. DTPI will hold a 49% ownership in the JV. Under the JV
agreement, CANTV guarantees minimum revenues to the JV and DTPI's share of such
revenues is approximately $50 million over the fifteen-year term of the
agreement.

        Acquisition of TI: As part of STM's strategy to leverage its existing
marketing and distribution channels through the acquisition of companies with
complementary products and services, in December 1997, the Company entered into
an Agreement and Plan of Merger with Telecom International, Inc. ("TI") pursuant
to which TI merged with and into a wholly-owned subsidiary of STM. TI was a
leading service provider that integrated and installed satellite communications
systems used in rural telephony and enterprise networks. Under the terms of this
acquisition, STM issued 480,000 shares of its Common Stock. The acquisition was
accounted for as a pooling of interests transaction and accordingly, all prior
period financial results have been restated to include the results of TI.

        Equity Financing: In March 1998, the Company completed a $10 million
equity offering of shares of STM and DTPI to Pequot Private Equity Fund L.P.
("Pequot"), the private investment vehicle of Dawson-Samberg Capital Management,
Inc. Through the transaction, Pequot acquired 571,429 newly issued shares of
common stock of STM.

        New Management Organization: In January 1998, the Company announced that
it would operate as three independent but related business units. Each business
unit will operate independently and have its own President. The re-organization
is intended to strengthen the Company's management. The three operating
divisions are:

        STM Network Systems combines the systems integration and digital video
business of TI with the core STM Wireless design, manufacture and sales of
satellite network systems;

        Direc-To-Phone International, Inc., as previously described, is the
Company's majority-owned rural telephony services subsidiary; and

        Telecom Multimedia Systems, Inc. is the Company's majority-owned
technology subsidiary which focuses on Internet telephony and voice over IP
solutions.

DESCRIPTION OF THE BUSINESS

        The Company, founded in 1982, develops, manufactures and markets
wireless based satellite communications infrastructure products to customers for
the creation of public and private networks. These networks are used to either
bypass or extend terrestrial networks or in some instances to provide a
communications infrastructure where a terrestrial network does not exist. The
Company's products provide customers with the ability to transmit many forms of
information including voice, fax, data and video. The Company sells its products
primarily in the international marketplace where the growing deregulation of
telecommunications markets and rapid economic growth stimulates the demand for
communications infrastructure. The solutions currently provided by the Company
are principally satellite communications networks which can be deployed and
reconfigured faster and at a lower cost than terrestrial alternatives. The main
products that STM sells are two-way small earth stations referred to as VSATs
(very small aperture terminals), associated infrastructure equipment and
software, transceivers, modems and other networking equipment.

        The Company's product line is based on proprietary hardware and software
used in the remote terminals, hubs/gateways and network management systems. The
Company's satellite communications product line includes products that are
capable of concurrently transmitting and receiving data as well as several
channels of digitized voice, using the Company's software to perform call
routing and to allocate satellite capacity on call initiation. These product
features allow more efficient use of satellite transponders and are attractive
to international customers for whom combined voice and data communications costs
are a prime concern.

        The Company has established alliances with customers, distributors and
sales representatives in over 30 countries and has supplied, both through STM
and TI, networks to customers or end users in many geographic areas, including
Argentina, Bosnia, Brazil, Canada, Chile, China, Columbia, Dominican Republic,
Ecuador, Germany, Haiti, Holland, Hungary, India, Italy, Kenya, Malaysia,

Mauritania, Mexico, Pakistan, Peru, Philippines, Poland, Sudan, audi Arabia,
Spain, Sudan, Thailand, the United States, Venezuela and Zambia.

INDUSTRY BACKGROUND

        VSAT products provide customers with the ability to transmit several
forms of information including voice, fax, data and video by attaching standard
communications equipment such as telephones, fax machines or computers to the
VSAT which in turn relays information to and from satellites. The primary
advantage of VSAT networks is the substantial cost savings compared to
land-based telephone networks where the network users are geographically
widespread. Due to the nature of satellites, transmission costs are not affected
by the distance information travels, while in terrestrial networks, transmission
costs are directly related to the distance between the network users. VSAT
equipment can be rapidly installed, upgraded or moved. Thus, networks can be
expanded or changed with relatively little expense and disruption to users.
Bandwidth allocated to each user can be changed dynamically, and the network can
be reconfigured and additional features and changes downloaded to the user.
Furthermore, the network user or service provider has the ability to monitor
operations of the network, collect performance statistics and perform
diagnostics.

        The Company divides the market for VSAT applications into two segments.
The rural telephony segment is comprised of providing basic telephony services
to rural or isolated areas of developing countries. The enterprise network
segment is comprised of business or government organizations that install
private networks or subscribe to services offered by independent operators to
provide communications between branch offices and corporate headquarters.

        Since the mid-1980s, the VSAT network market has grown with the North
American enterprise network market share dominating. In recent years, changes in
both the political and regulatory environments have contributed to the
international expansion of the VSAT network market. While the North American
market is primarily for data transmission applications, in most international
markets, applications for basic telephony services including voice, facsimile
and low speed data transmission are important. Recently, VSATs have emerged as a
compelling solution for providers of such basic telephony services in developing
countries. In certain developing countries where existing communications systems
are inadequate for the growing economy, VSATs are a practical method of quickly
making available sophisticated communications capabilities. A significant growth
opportunity for these capabilities is rural telephony, the provision of
telephone facilities to villages located in remote or difficult terrain.

        In response to the current opportunity that exists for the provision of
products and services in the rural telephony market, the Company is incurring
significant expenditures on developing improved products that are especially
suitable for rural telephony applications and should result in the availability
of lower priced, high quality rural telephony products. Additionally, due to the
similarities between rural telephony and enterprise network products, the
Company's research and development expenditures should also result in the
availability of lower priced, high quality enterprise network products.

RURAL TELEPHONY MARKET

        As the world's economies continue to globalize, the need for countries
to provide their population with access to telecommunications service has become
significantly more important as a means of increasing competitiveness. In
developed countries, the International Telecommunications Union reports estimate
that the average telephony penetration is over 50 lines per 100 inhabitants,
while the overall global penetration is still under 15 lines per 100
inhabitants, and in certain developing countries, less than two lines per 100
inhabitants. In response, many developing countries throughout



                                       4

<PAGE>   5

the world have begun to make significant capital expenditures on the deployment
of new networks and the expansion of their existing telephone infrastructure to
increase telephony penetration. While traditional terrestrial telecommunications
networks are being deployed and expanded in the urban areas of these developing
countries to increase telephony penetration, it is more difficult to provide
networks to the rural areas of these countries due to the dispersion of the
population and difficult terrain that often characterizes these locations. As a
result, in a large number of remote and rural areas in developing countries,
there continues to be limited or no telephone service.

        To date, the local telephone service providers in less developed
countries, where the need for rural telephony is greatest, have focused their
attention on developing and increasing the telephony penetration in urban areas,
which they have considered better short-term opportunities to increase revenues
at a lower cost, rather than providing rural telephony. In response to the need
for telephone service in rural areas, governments are increasingly putting
pressure on the telephone service providers to offer universal service coverage
by ensuring telephony availability in these regions. Deregulation of the
telecommunication markets in these developing countries has led to increased
competition and many governments are requiring the domestic telephone companies
to fulfill certain rural telephony obligations as a prerequisite to renewing
their licenses. The Company believes that this increased emphasis on providing
rural telephony services will generate significant market opportunities
primarily in Latin America, Asia/Pacific and Eastern Europe.

        There are a number of alternatives to satellite technology that are
being used to meet increased demand for telecommunication services. Wireline and
cellular telephony networks can be used to effectively meet telecommunications
needs in rural areas with relatively higher population densities. However, in
many of the rural areas of developing countries, villages can be scattered
sometimes several hundred miles apart and may be inaccessible by road at all
times due to harsh terrain or at certain times of the year due to climatic
conditions. In addition, the spending power of the inhabitants of those villages
has limited the subscriber count. Satellite telephony networks offer significant
advantages compared to traditional telephony systems in these areas. The
following describes the primary disadvantages of using alternative technologies
in these markets:

        Wireline systems: Wireline systems involve the laying of fiber or copper
        wires between the telephone operating company's central office and each
        subscriber's home or office. The principal drawbacks of wireline systems
        include: expense of constructing networks over long distances and rough
        terrain; susceptibility to weather and vandalism and long construction
        time.

        Cellular systems: Cellular systems involve the use of a cellular phone
        to communicate directly with a locally installed base station
        transmitter which, in turn, switches the communication to the intended
        recipient. The principal drawbacks to cellular systems for rural
        telephony arise from the limited geographical coverage of cellular base
        stations resulting in the need for a relatively high population density
        over which to spread the infrastructure costs of the many base stations
        needed.

        Wireless local loop systems ("WLL"): Much like cellular systems, typical
        WLL systems involve the use of fixed or mobile telephone handsets to
        communicate with locally installed base station transmitters. WLL
        systems are generally designed for higher density applications than
        those addressed by the Company. However, due to their lower cost and
        efficiency for local distribution WLL systems can be used as a
        complementary distribution product in satellite-based rural telephony
        networks and the Company is examining such combined product solutions.



                                       5

<PAGE>   6




        Microwave systems: Microwave systems involve the use of microwave radios
        to communicate directly between two points. The principal drawbacks to
        microwave systems are the high cost of providing service and limited
        service availability in rough terrain due to the requirement for a line
        of sight between the two points. Many rural areas are not easily
        accessible and the terrain makes the cost of constructing many microwave
        towers with relay sites prohibitive.

        Mobile satellite systems ("MSS"): Mobile satellite systems involve the
        use of hand held phones to communicate typically via Low Earth Orbiting
        Satellites ("LEOS"). In the MSS model, the LEOS act as a replacement for
        the local base station transmitter of cellular systems but provide much
        greater range based on the satellite footprint. No MSS systems are
        currently in operation and the first major one (Iridium) is not
        scheduled to be available until later in 1998. Due to the high cost of
        satellite construction and launch, MSS systems are expected to have much
        higher usage costs. This predicates against their use as a viable
        replacement of VSATs for the rural telephony market.

        In summary, the Company believes that VSAT networks have a number of
advantages over alternative solutions for many rural and urban telephony
applications in developing countries where low population density and rough
terrain are considerations. Due to the nature of satellites, transmission costs
are not affected by the distance signals must travel. Therefore, generally, the
greater the distance between the sites to be served, the greater the benefit of
a VSAT network. VSAT equipment can be rapidly installed and connected to a
network and can easily be upgraded, expanded or relocated with relatively little
expense and disruption. VSAT networks are relatively simple to reconfigure, are
relatively immune to difficulties in topography and can be located almost
anywhere.

        To complement its product offerings, the Company is developing a WLL
product and is considering entering into strategic relationship with other
providers of WLL products, thereby ensuring that the Company has an economical
product offering in more densely populated regions.

ENTERPRISE NETWORKS

        Enterprise networks are private communications systems which provide a
solution for organizations with frequent communications needs between remote
locations allowing them to collect, process, respond to and disseminate
information in a timely, reliable and cost-efficient manner. VSATs have
historically been used in developed countries for transaction oriented
applications, including point-of-purchase transactions, credit card
verification, automatic teller machine transactions, and inventory management.

        In recent years, the price of VSATs has decreased, their functionality
and reliability have improved and the number of communication protocols that can
be supported has increased. These improvements allow VSAT networks to compete
effectively as full service communications systems in international markets
where the lack of reliable terrestrial networks necessitates the use of
alternative telecommunication infrastructure. In addition to transaction
oriented applications, international VSAT enterprise networks are used for
communications applications such as e-mail, intranets, Internet access and basic
voice service. The Company believes that the need for these advanced
telecommunication services coupled with the lack of infrastructure to provide
these services will cause the international VSAT enterprise network market to
grow much more rapidly than the domestic market.

        Historically, the concentration of sales of VSATs in the United States
and other developed countries has been primarily to large corporations for
transaction oriented enterprise networks. It is believed that over 60% of
worldwide installations for enterprise network VSAT terminals are in North
America. The Company has focused its efforts in the international markets due to
the more favorable competitive



                                       6

<PAGE>   7

environment, the growth potential of the market, especially in rural telephony
and other services and the Company's overseas operating experience.

BUSINESS STRATEGY

        STM seeks to leverage its technical strength in networking and telephony
technologies as well as its strong position and marketing expertise in
international markets to become the leading supplier of satellite-based
communications solutions to emerging countries. To achieve this objective, the
Company is pursuing the following initiatives:

        Solidify Leadership Position in Rural Telephony Market: In a large
number of rural areas in developing countries, telephone service is limited or
non-existent. Often such areas are characterized by rough terrain, low
population density and a harsh climate. As deregulation and economic necessity
have spurred demand in developing nations for telecommunications infrastructure,
many countries have mandated that their telephone companies provide telephony
services to rural regions. The Company believes that satellite communications
networks, which can be deployed and reconfigured faster and at a lower cost than
terrestrial and microwave transmission alternatives, offers a cost effective
solution for these regions.

        Management believes that STM offers a comprehensive rural telephony
solution through a suite of products specifically designed to service these
needs. The competitiveness of the Company's product portfolio and system
architecture is evidenced by the fact that during 1997, STM was awarded
contracts for three major rural telephony projects in Mexico, Venezuela and
Thailand for approximately $180 million. Of these contracts, $30 million was
attributable to an equipment supply contract and $150 million was attributable
to long-term service contracts through DTPI. Management believes that the use of
VSATs for rural telephony is currently in its infancy and a substantial global
market opportunity exists for this technology to serve rural telephony needs.

        Expand Market Share in Enterprise Networks: VSAT networks are also used
by organizations with numerous geographically dispersed locations and frequent
communications needs between those remote locations. VSAT-based enterprise
networks are attractive to customers due to the substantial cost savings as well
as the higher level of flexibility and control these networks offer compared to
traditional telephone service. Both political and regulatory advances have
contributed to the international market growing faster than the domestic market.
The Company's enterprise network strategy is to capitalize on its international
expertise to sell products in the growing international market.

        To that end, the Company acquired TI, whose business is the integration
and installation of large satellite terminals used in rural telephony and
enterprise networks. Management believes that supplementing the Company's
enterprise network expertise with the TI expertise and experience should
increase the Company's ability to capitalize on market opportunities.

        Leverage Existing Marketing and Distribution Channels: STM's sales and
distribution networks comprise 30 countries in five continents and the
Company's products are currently utilized by more than 70 customers with
equipment installed in approximately 90 countries. The Company seeks to increase
the breadth of products that can be sold through its distribution network by
both internal research and development ("R&D") and strategic alliances with
other manufacturers, as well as complementary acquisitions. STM has incurred
significant R&D expenditures in recent years relative to its revenues, as
management believes that the Company's significant dedication of resources to
R&D is the primary reason for the competitive edge and market leadership of the
Company's product portfolio. STM's R&D efforts are primarily focused on reducing
the overall cost of its products to its customers, as well as increasing their
performance, thereby expanding the



                                       7

<PAGE>   8

addressable market size.

PRODUCTS

        The principal products sold by the Company are two-way small earth
stations referred to as VSATs (very small aperture terminals), associated
infrastructure equipment and software, transceivers, modems and other networking
equipment, as well as voice over IP gateway and software solutions. The
Company's satellite products communicate via geostationary satellites in order
to provide customers the ability to exchange several forms of information
including voice, fax, data and video within their networks. Geostationary
satellites are placed in orbit approximately 23,000 miles above the earth so
that their orbit matches the speed of the earth's rotation resulting in the
satellite maintaining a fixed position relevant to the earth's surface. VSAT
networks can offer advantages over traditional networks of terrestrial telephone
lines including control over the network itself, improved response times with
cost reduction opportunities and increased flexibility and reliability. For
voice communications, VSAT networks are particularly suited to providing
communications between geographically dispersed locations in that they are
easier to install and provide wider accessibility and availability than
terrestrial and microwave transmission alternatives.

        The Company's VSAT products fall into two principal families: DAMA 10000
and X.STAR. Both of these product families may be used by customers to build
networks capable of communicating voice, fax, data and video, but, because they
use different architectures, the use of each product is determined by the
particular needs of the customer's network. The principal difference between the
two product families lie in the methodology used for communicating between any
two remote VSATs on a network. DAMA 10000 is what is often termed a "mesh"
product and employs circuit switched transmission. In mesh networks, any one
VSAT communicates directly with any other VSAT on the network via a single
transmission to and from the satellite. X.STAR, however, is what is often termed
a "star" product and employs packetized transmission.

Existing Products and Products Under Development

        Satellite Products:

        DAMA 10000: The Company's DAMA 10000 product primarily supports public
and private networks that need to have full connectivity among all sites. The
DAMA 10000 is a fully integrated product that offers the flexibility to create
and manage both large and small networks. With an expandable system architecture
and highly configurable terminal equipment, the DAMA 10000 is a cost efficient
solution for small to very large networks. The system supports full mesh,
point-to-point or point-to-multi-point communications circuits and any user can
connect to any other user on the network. DAMA 10000 uses a proprietary control
channel to set up and tear down calls between VSATs as these are requested by
users on the network. This results in satellite capacity only being consumed
when calls are requested, thereby optimizing satellite transponder costs for the
customer. In addition, DAMA 10000 provides support for the major international
telephony signaling systems including R2 and DTMF as well as various payphone
metering schemes, allowing it to be interconnected with the Public Switched
Telephony System ("PSTN") in many countries around the world. These features of
the product have resulted in it being ideally suited for rural telephony
applications where individual VSATs provide multiple telephone lines to
subscribers in remote locations. These VSATs are, in turn, all interconnected
via satellite with the PSTN in the country of deployment providing the remote
subscribers with worldwide calling capability.

        Subscriber Earth Station: The Company's Subscriber Earth Station
("SES"), currently under development, is expected to be a low cost telephony
product derived from and compatible with DAMA 10000. As an extension of DAMA
10000, the SES will be targeted at the provision of



                                       8

<PAGE>   9

telephony services to unserved or underserved regions of the world. SES will be
designed to provide reliable, affordable, on-demand telecommunications service
in remote and rural areas. SES will be a small, light weight and low cost
terminal ideally suited for areas where telecommunications service is
unavailable, unreliable or simply too expensive. Since it will be
satellite-based, an SES terminal will be capable of being installed quickly,
virtually anywhere, to allow immediate access to the SES network and the PSTN.
SES will provide telecommunications service with high quality voice and industry
standard interfaces. It is expected that the SES will be available in 1998.

        X.STAR: The Company's X.STAR product primarily supports private networks
with a need to connect remote user locations with a central site. A typical
application of an X.STAR network would be the processing of point of sale
transactions between retail outlets and a central database. However, the X.STAR
product supports all types of data including voice, fax and broadcast video and
more recently has been used by customers to interconnect LANs across their
enterprises. The network is controlled by a central hub that acts as a gateway
to the host facilities and as a switching and routing center for transmitting
information between VSATs. A powerful network management system ("NMS") is also
a part of the hub and multiple remote NMS stations may be deployed on the
network.

        In an X.STAR network, VSATs all receive a common broadcast signal from
the hub, filtering the data received to accept only the information addressed to
devices connected to the VSAT. In order to transmit information back to the hub
or to another VSAT via the hub, VSATs on the network share a common transmit
channel back to the hub. Access to this transmit channel is controlled by the
Company's unique dynamic capacity allocations algorithm which allocates a
transmission time and duration to each VSAT dynamically based on its traffic
requirements.

        X.STAR uses a packet-based transmission and switching protocol that
makes it suitable for the transmission of packetized data which is increasingly
being used in today's communications networks including the Internet. This
protocol establishes and maintains error-free channels from initiation points to
destination points on a network. In addition, the X.STAR product supports most
major communications protocols including SDLC, X.25, X.3, HDLC and TCP/IP,
resulting in seamless transport of information using these protocols across an
X.STAR network.

        SpaceWeb: The Company's SpaceWeb product, currently under development,
is an evolutionary development of the X.STAR family and will be fully compatible
with X.STAR. SpaceWeb will provide a low cost, star-connected solution for data,
fax and voice applications and is aimed at international Internet access.
SpaceWeb will be a low cost terminal that communicates with a low cost central
hub whose modular architecture will be designed to provide attractive start up
costs, without restricting network growth potential. For reliable end to end
communications, SpaceWeb will utilize the Company's X.STAR communications
protocol and will support all of the same communications protocols as X.STAR. It
is expected that SpaceWeb will be available in 1998.

        Hubs/Gateways: The Company manufactures the digital and modem portion of
the hubs/gateways which are comprised of a series of special purpose processing
units utilized in multiplexing, network configuration and routing of information
to the appropriate network destinations. This is controlled by the Company's
proprietary networking and system software. Typically, the digital portion of
the hub/gateway has a number of voice and data ports that directly attach to the
user's equipment. Transmission between the hub/gateway and the remote VSAT is
via a satellite transponder. The hub/gateway also includes radio frequency
components and an antenna, which are purchased from suppliers and integrated
into the system by the Company. The hub/gateway interacts with a network
management system, which operates on a local or remote work station using
proprietary software supplied by the Company.



                                       9

        Network Management Systems: The Company provides a network management
system which shows network status in real time, and permits the operator to
monitor and control network operations, including the diagnosis of problems. The
interface with the operator is by a graphic display of the network status on a
color monitor. The network management system can also be used for redefining
network parameters, for adding and deleting remote network locations, for
changing protocols and for collecting and reporting operational information and
providing management reports. In addition, the system can be expanded if the
hub/gateway is shared among several customers, to permit each customer to have
such capabilities. The network management system can be installed remotely from
the hub/gateway location if required.

        Systems Integration Products: The Company also integrates equipment from
other manufacturers into systems or earth stations manufactured by the Company.
These products include antennas, radio frequency equipment, satellite modems,
voice and data multiplexers, local area network routers and video communications
equipment. The STM Network Systems division expects to continue to sell such
systems on an individual project basis as part of its direct sales effort.

        Terrestrial Communications Products:

        Internet and Frame Relay Products: Through its subsidiary, Telecom
Multimedia Systems Inc. ("TMSI"), the Company has introduced another line of
communication products. TMSI's core technology is a proprietary software
platform (CLEARCONNECT(TM)) that acts as an operating system kernel for a
variety of compression and signaling technologies utilized for the transport of
voice, fax and data over communications networks. TMSI's CLEARCONNECT(TM)
platform supports many International Telecommunications Union ("ITU") standards
for digital voice compression including G.711, G.165, G.721/G723, G723.1, G.726,
G.728 and G.729. In addition, TMSI supports the AMBE algorithm for low bit rate
voice as well as Group III fax and modem relay up to V.32bis. With such a
comprehensive suite of compression protocols supported, TMSI provides the
Company with state of the art voice, fax and modem transport in its DAMA 10000,
SES, X.STAR and SpaceWeb product lines.

        TMSI has also deployed its software on its own hardware platforms.
TMSI's Lepton product family is used by customers to compress and transport
information over public and private communications networks. The Lepton offers a
variety of standard user and network interfaces which when combined with the
CLEARCONNECT(TM) software allow users to maximize the amount of information
transported over a given amount of terrestrial or wireless capacity thereby
reducing the cost of transmission facilities for the customer.

        TMSI's Lepton products can also be used to connect legacy telephony with
the Internet. The introduction of telephony services over the Internet is vital
for realizing true multimedia services. TMSI's suite of technologies for voice
and facsimile compression, telephony operating systems, signaling and other
related functions can readily be used for seamless voice communication over
packet switched networks including the Internet.

        TMSI's products are all capable of remote management using its
MediaMaster network management system. MediaMaster provides users with a
friendly Graphical User Interface ("GUI") for monitoring and controlling
different aspects of the equipment and software. In addition, MediaMaster is
being enhanced to offer customers the capabilities for user authentication,
billing and directory services.

SERVICES

        Rural Telephony Services: Utilizing equipment manufactured by STM and
others, DTPI, through joint ventures and partnership agreements with local
telecommunication service providers, provides rural telephony services in
developing countries. DTPI invests in the joint ventures, contributes



                                       10

<PAGE>   11

technology, know-how and expertise, while the local partners maintain the
operating licenses, and provide frontline customer service, as well as
contributing their share of the required investment. See Recent Events for a
more detailed review of DTPI.

        Project Management: The Company offers engineering, project management,
and contract services in support of products sold.

        Custom Development: From time to time the Company receives orders from
its customers and distributors for product features, new products or software
protocols and functions that enhance the Company's product lines. While such
custom development orders do not contribute significantly to the Company's
revenues, they demonstrate the Company's ability to be responsive to market
requirements.

        Technical Support Services: The Company provides technical support
services to its installed base of customers either directly or through
third-parties. Services include technical support, installations, maintenance,
training and spares provisioning.

SALES AND MARKETING

        Network Systems Division: The Company sells its satellite communication
products directly and through international distributors and alliances which are
supported by the Company's sales and marketing personnel. With the recent
re-organization of the business into three independent but related business
units, the Network Systems division has focused its sales efforts on the
following:

    o      Expanding global coverage through increasing the number of highly
           trained direct sales personnel with regional responsibilities

    o      Identifying sales opportunities that exist with newly licensed
           service providers in international markets, particularly those
           focused on providing rural telephony services

    o      Identifying capable local distributors and replacing, if necessary,
           its current distributors and alliances

    o      Supplying highly integrated low cost solutions to customers through
           the Company's product offerings.

        Direc-To-Phone International, Inc.: DTPI was founded as a separate
business unit of STM with the intention of becoming the predominant provider of
Direct To Home telephony services in developing countries. To date, DTPI has
been awarded two long-term service contracts for the provision of rural
telephony services in Mexico and Venezuela. Both of these contracts are with
local, in-country partners who are the license holders in the respective
countries and include a guaranteed minimum level of revenue by the local
in-country partner to subsidize the initial service. DTPI aims to increase
penetration and volume by moving toward consumer level pricing and operation. To
achieve this, DTPI is focused on the following:

    o      Being the first to market a fixed satellite telephony solution, on a
           mass scale, with a consumer oriented product that can satisfy the
           demand in unserved areas;
    o      leveraging the marketing, operating and technical capabilities of
           local partners for each region or country;
    o      providing potential subscribers and users with a high quality
           telephone and other added value services;
    o      employing a system design that has the lowest recurring cost compared
           to other satellite-



                                       11

<PAGE>   12

           based competing systems;

    o      offering domestic long distance calls, to the extent possible from a
           regulatory standpoint, at the same basic per minute rate as local
           calls;
    o      employing a consumer oriented sales and marketing strategy that
           differentiates the Company from others and provides for a higher
           level of product acceptance by end users; and
    o      seeking strategic partners who can further increase the visibility
           and market penetration of the Company's services.

        Export sales, as a percentage of revenues, were approximately 96%, 91%
and 95% in 1997, 1996 and 1995, respectively. In 1997, sales to a single
customer in Thailand accounted for approximately 59% of revenues. No other
customer accounted for greater than 10% of revenues in 1997. Reference is made
to Note 12 of the notes to the consolidated financial statements - Sales to
Principal Customers, Geographic Regions and Concentration of Credit Risk in Item
8 - "Financial Statements, Financial Statement Schedule and Supplementary Data".

BACKLOG

        The Company's backlog represents all future revenues that may be earned
from signed sales orders or sales contracts for products or services. As of
December 31, 1997, the Company's backlog was approximately $153.2 million,
comprising approximately $150 million in long-term service contracts and
approximately $3.2 million for products. At December 31, 1996, the Company's
product backlog was approximately $9.0 million. Based on current estimates,
approximately $145 million of the long-term service backlog will not be filled
in 1998. The Company manufactures its products on the basis of customer orders
and its forecast of near-term demand from its customers and for use by DTPI in
its service business. The Company conducts nearly all of its business with
foreign customers in United States currency and accordingly, is generally not
subject to foreign currency fluctuations. Customary terms of business for
product sales are a substantial deposit on order with the remainder guaranteed
by an irrevocable letter of credit or, when appropriate, open account. For DTPI,
the terms of business for its existing contracts include an initial fee payable
upon the telephone lines being commissioned. In addition, there are revenue
sharing arrangements based upon actual revenues earned and guaranteed monthly
fees. The service backlog at December 31, 1997, represents the value of the
guaranteed minimum revenue sharing and the initial fees.

MANUFACTURING

        The Company's products are assembled by the Company using subsystems and
circuit boards supplied by subcontractors. The Company's microwave products are
designed and fabricated utilizing microwave components manufactured by outside
suppliers. The Company maintains adequate stock to reduce the procurement lead
time for certain components. The Company's products use a number of application
specific integrated circuit (ASIC) chips, monolithic microwave integrated
circuits (MMIC) and customized components or subassemblies produced by a limited
number of suppliers. In the event that such suppliers are unable to fulfill the
Company's requirements, the Company may experience an interruption in production
until an alternative source of supply is developed. The Company maintains an
inventory of certain long lead time components and subassemblies to limit the
potential for such an interruption. The Company believes that there are a number
of companies capable of providing replacements for the types of unique chips,
customized components and subassemblies used in its products.

RESEARCH AND DEVELOPMENT

        The Company's research and development efforts are devoted to the design
and implementation of satellite and wireless radio communications network
hardware and software, along with voice over IP software and hardware solutions.
The Company's future growth depends on adaptation of its existing satellite
communications products to new applications, and the introduction of new
communications products that will gain market acceptance and benefit from the
Company's established international distribution channels. Accordingly, the
Company is actively applying its communications expertise to design and develop
new hardware and software products and enhance existing products.

        STM's R&D efforts are primarily focused on reducing the overall cost of
ownership of its products to its customers, thereby expanding the addressable
market size. For example, the Company is developing two new low cost products;
Subscriber Earth Station, aimed at the rural telephony market, and SpaceWeb to
provide fast internet communication in enterprise networks. The Company believes
that these products will be priced low enough to attract a large market
internationally, and expects to begin shipping them in 1998. In addition, the
Company may opportunistically acquire products, technologies or companies
consistent with its commercial objectives to serve the evolving needs of the
Company's customer base.

        In 1997, 1996, and 1995, the Company incurred expenses of $6,387,000,
$6,895,000, and $3,677,000 respectively, on research and development activities.
During this period, the Company enhanced the TXR-3000 VSAT, and continued the
development of the DAMA 10000 VSAT, SMR 2000, SCPC C-Band satellite transceiver,
and started development of the Subscriber Earth Station, SpaceWeb and Internet
telephony products.

COMPETITION

        Network Systems Division: The Company has a number of competitors in the
satellite communications field, most of which have substantially greater
financial, marketing, and technological resources than the Company. The
Company's competitors include large companies such as Hughes Network Systems
and Scientific Atlanta, all of whom compete to some extent in some international
markets. There can be no assurance that the Company will not experience
increased competition in the future from these or other competitors which may
adversely affect the Company's ability to continue to successfully market its
products or services. The Company believes that it has been able to compete with
these companies by offering flexible and cost effective products and utilizing
the resources of local distributors, forming strategic alliances with major
corporations, and by emphasizing product features and functions such as
concurrent support of multiple protocols, voice capability, built-in diagnostic
ports and downloadable software and configurations, which allow the products to
serve the diverse needs of international customers. These product features and
functions are based upon the Company's proprietary hardware and software.
See "Patents and Intellectual Property."

        However, most of the Company's competitors offer products which have one
or more of the features and functions similar to those offered by the Company.
The Company believes that the quality, performance and capabilities of its
products, its ability to customize certain network functions and the efficient
utilization of satellite capacity, coupled with the products generally offered
by the Company's major vendors, have contributed to the Company's ability to
compete successfully. The Company's major competitors have the resources
available to develop products with features and functions, competitive with, or
superior to, those offered by the Company. There can be no assurance that such
competitors will not develop such features or functions, or that the Company
will be able to maintain a lower cost advantage for these products.

        Direc-To-Phone International, Inc.: DTPI deploys wireless-based
communication infrastructure products utilizing geostationary satellite
spectrum. Geostationary satellites are placed in orbit approximately 23,000
miles above the earth so that their orbit matches the speed of the earth's
rotation resulting in the satellite maintaining a fixed position relative to the
earth's surface. This gives a fixed area of coverage, or footprint, in which
satellite networks can operate. This distance above the earth also produces two
drawbacks of geostationary satellites. First, because there is a significant
distance traveled, there is a noticeable delay (approximately 250 msec) between
transmission and reception. This can be disconcerting in voice networks,
especially if a double-hop (or two transmissions) is needed because of the
network design. DTPI uses full-mesh products which minimize this delay and so it
is not a significant factor in DTPI rural telephony networks. A similar delay
occurs on many standard international calls when the trunking is done by
satellite transmission. The second disadvantage is, due to the long distance,
transmission power and reception sensitivity needs to be greater than for the
LEOS (see below). This means larger equipment which precludes mobile telephony.
However, in the rural telephony market, mobility is not a requirement.

        DTPI's potential direct competitors in the geostationary rural telephony
service arena are suppliers of geostationary networks such as Hughes,
Scientific-Atlanta, SPAR/Comstream and Gilat. However, due to the significant
investments in technology made by STM in the past years, it is believed that STM
presently holds a strong competitive position in rural telephony products.
Furthermore, with DTPI's successes in Mexico and Venezuela and STM's prior rural
telephony sales in Thailand and Argentina, the Company believes DTPI is a leader
in rural telephony solutions. Other geostationary satellite-based competitors
include American Mobile Satellite Corporation (AMSC), Asia Pacific Mobile
Telecom (APMT), Afro-Asian Satellite (ASC), Asean Cellular System (ACS) and
Comsat.

        Mobile Satellite Systems (MSS) use Low Earth Orbit Satellites (LEOS).
LEOS, because of their low proximity to the earth, move in relation to the
earth's surface, therefore, a constellation of satellites is needed. At any one
time, two or more satellites must be in sight of the user in order to carry out
a successful call handoff if the active satellite disappears below the horizon.
This adds to the complication and expense of the MSS offering. MSS does have two
advantages - smaller handheld terminals and lower voice transmission delay.

        However, DTPI considers its most immediate and serious competition to
come from MSS. Despite their potential higher cost of service, compared to DTPI,
their financial projections include significant penetration into the unserved
and underserved areas of developing countries. Despite the advantages of a
mobile service, DTPI believes that the high cost of MSS service will make its
geostationary solution a more realistic solution for telephony service in remote
areas.

PATENTS AND INTELLECTUAL PROPERTY

        The Company relies on a combination of trade secrets, copyrights,
trademarks, service marks and contractual rights to protect its techonoloy and
software. The Company attempts to protect its trade secrets and other
proprietary information through agreements with its customers, suppliers,
employees and consultants. Except for terrestrial and low cost telephony
products, the Company does not have patent protection on any aspect of its
technology or software. The Company believes that the improvement of existing
products, reliance upon trade secrets, copyrights and unpatented proprietary
know-how and the development of new products are generally as important as
patent protection in establishing and maintaining a competitive advantage
because, among other reasons, patents often provide only narrow protection which
may not result in a competitive advantage in areas of rapid technological
change. Further, patents require public disclosure of information which may
otherwise be subject to trade secret protection. The Company believes that the
value of its products is dependent upon its proprietary software and hardware
remaining "trade secrets" or subject to copyright protection.



                                       14

<PAGE>   15


However, with its venture into new fields such as terrestrial and low cost
telephony products, the Company believes that patent protection may be more
appropriate. Accordingly, the Company has applied for one patent and is in the
process of pursuing one additional patent. However, there can be no assurance
that the Company's proprietary technology will remain a trade secret, or that
others will not develop a similar technology and use such technology to compete
with the Company. In addition, the laws of certain countries in which the
Company's products are or may be developed, manufactured or sold may not protect
the Company's products and intellectual property rights to the same extent as
the laws of the United States. The inability of the Company to protect its
intellectual property and proprietary technology could have a material adverse
effect on its business, operating results and financial condition. As the number
of patents, copyrights and other intellectual property rights in the Company's
industry increases, and as the coverage of these rights and the functionality of
the products of new markets further overlap, the Company believes that its
products may increasingly become the subject of infringement claims. The Company
may in the future be notified that it is infringing upon certain intellectual
property rights of others. Although the Company has not received any such
notification to date, and there are no pending or threatened intellectual
property lawsuits against the Company, there can be no assurance that such
litigation or infringement claims will not occur in the future. Any such
litigation or claims could result in substantial costs and diversion of
resources and could have a material adverse effect on the Company's business,
operating results and financial condition.

GOVERNMENT REGULATIONS

        The Communications Act of 1934, as amended, gives the Federal
Communications Commission ("FCC") jurisdiction over the communications products
and services provided by the Company in the United States. Part 25 of the FCC's
rules and regulations governs the operation and use of satellite transponders
and requires authorization for construction and operation of each transmitting
earth station, including VSATs installed on customers' premises. The Company
believes it has received all authorizations from the FCC required to date in the
operation of its two-way VSAT network in the United States.

        The Company's international sales are also subject to Department of
Commerce regulations for export of its products, which usually meet general
license requirements depending on country of destination.

EMPLOYEES

        As of December 31, 1997, the Company employed 208 people on a full-time
basis, including 45 employees in engineering/research and development, 64
employees in manufacturing, 27 employees in marketing and sales, 32 employees in
administration and accounting, and 40 employees in customer service and support.

        The Company believes that its relations with all employees are
satisfactory. The employees and the Company are not parties to any collective
bargaining agreements.

LONG TERM CYCLES INVOLVED IN COMPLETING MAJOR CONTRACTS, PARTICULARLY IN FOREIGN
MARKETS, INCREASING COMPETITIVE PRESSURES, GENERAL ECONOMIC CONDITIONS,
TECHNOLOGICAL ADVANCES, THE TIMING OF NEW PRODUCT INTRODUCTIONS, POLITICAL AND
ECONOMIC RISKS INVOLVED IN FOREIGN MARKETS AND FOREIGN CURRENCIES AND THE TIMING
OF OPERATING AND OTHER EXPENDITURES.

        BECAUSE OF THESE AND OTHER FACTORS THAT MAY AFFECT THE COMPANY'S
OPERATING RESULTS, PAST FINANCIAL PERFORMANCE SHOULD NOT BE CONSIDERED AN
INDICATOR OF FUTURE PERFORMANCE, AND INVESTORS SHOULD NOT USE HISTORICAL TRENDS
TO ANTICIPATE RESULTS OR TRENDS IN FUTURE PERIODS.

 HISTORY OF LOSSES AND FLUCTUATIONS IN QUARTERLY OPERATING RESULTS

        Results of operations may fluctuate significantly and will depend upon
numerous factors, including the competitive environment in which the Company
operates, the delays that arise when operating in an international environment,
the long lead time and extended sales effort required to secure larger value
orders that the Company focuses on obtaining, the continued need to invest in
the development of new products and in the enhancement of existing products, the
risk of inventory obsolescence and the exposure to disputes by international
customers.

        The Company has incurred operating losses in both 1997 and 1996 and may
incur losses in 1998. However, the Company has taken certain actions that it
believes should improve the operating results of the Company. Management
believes that through investing in DTPI as a service business with long-term
recurring revenues, the Company, over time, will be able to generate a more
stable pattern of business. In addition, the Company has recently reorganized
itself internally to focus clearly on its three main businesses and has
strengthened its management team through the acquisition of TI in December 1997.
It is believed that these actions should lead to improved operating results.
However, there can be no assurance that there will not be operating losses in
the future periods, or that the Company's reorganization will lead to improved
operating results.

     The Company's quarterly operating results fluctuate primarily due to the
timing of product sales. Sales of the Company's products are generally
consummated through large orders which require a long lead-time and an extended
sales effort. The Company's sales in any quarter are dependent on orders booked
and shipped in that quarter. As a result, the precise timing of the recognition
of revenue from an order can have a significant impact on the Company's total
revenues and operating results for a particular period. The Company's operating
results for a particular period could be adversely affected if an order is
cancelled or rescheduled by customers or cannot be shipped in time to recognize
revenue during that period due to, for example, unanticipated manufacturing,
testing, shipping or product acceptance delays. In addition, the Company's
expense levels are based, in large part, on the Company's expectations as to
future revenues and are, therefore, relatively fixed in the short term. If
revenue levels fall below expectations, net income will be disproportionately
and adversely affected. The impact of these and other factors on the Company's
revenues and operating results in any future period cannot be forecast with any
degree of certainty. Accordingly, the Company believes that period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as an indication of future performance. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."



                                       16

<PAGE>   17

DEPENDENCE ON VSAT MARKET

     A significant part of the Company's product revenues are derived from sales
of VSAT communications networks. While the market for VSAT communications
networks and services has grown steadily since its inception in the mid-1980s,
there can be no assurance that this market will continue to grow or that the
technology serving this market will not be replaced by an alternative
technology. A significant slowdown in this market or the replacement of the
existing VSAT technology by an alternative technology could have a material
adverse effect on the Company's business, operating results and financial
condition.

DEPENDENCE ON ASIAN MARKETS

     The Company generated 68%, 53% and 40% of its revenues in Asia in 1997,
1996 and 1995, respectively. In addition, the Company generated approximately
59%, 33% and 6% of revenues from one Asian customer in 1997, 1996 and 1995,
respectively. While in any individual year, the Company's revenues generally
represent new projects to new or existing customers in new or existing
geographic regions, there can be no assurance that the recent turmoil in the
Asian economies will not have any impact on the level of revenues generated by
the Company in this market in future years and that any shortfall in such
revenues will not have a material adverse effect on the results of operation and
financial condition of the Company.

RURAL TELEPHONY MARKET

     The Company's strategy includes focusing on establishing rural telephony
networking infrastructure for developing countries through strategic alliances
with regional and local service providers. There can be no assurance that a
substantial market for rural telephony equipment in developing countries will
ever develop, or if such a market does develop, that fixed-site VSAT-based
equipment will capture a significant portion of that market. The Company's
ability to penetrate this market will be dependent on its ability to develop
equipment and software which can be utilized by regional and local service
providers to market and sell the use of such systems. Furthermore, there can be
no assurance that the regional and local service providers will be able to
successfully market such services to rural subscribers.

SALES TO FOREIGN CUSTOMERS

     The Company's success is dependent upon its ability to continue to
successfully market voice and data VSAT communication networks in the
international market. The Company's export sales, as a percentage of total
revenues, were approximately 96%, 91%, and 95% in 1997, 1996 and 1995,
respectively. As a result, the Company is subject to various risks, including
currency fluctuations, greater difficulty of administering business globally,
compliance with multiple and potentially conflicting regulatory requirements,
such as import requirements, tariffs and other barriers, differences in
intellectual property protections, difficulties in staffing and managing foreign
operations, longer accounts receivable cycles and delays in resolving customer
disputes, repatriation of earnings, export control restrictions, overlapping or
differing tax structures, political and economic instability and general trade
restrictions. If any of these risks materializes, it could have a material
adverse effect on the Company's business, operating results and financial
condition. In addition, the satellite network service industries in the
Company's target markets are highly regulated, which may limit the number and
identity of potential service providers to which the Company can sell its
products. Given the high degree of regulation in the Company's target market,
and given the fact that such markets, which are primarily developing countries,
involve greater political and economic instability, there can be no assurance
that the Company's products will achieve general market acceptance in the
Company's target markets. The Company's foreign sales are generally invoiced in
U.S. dollars. However, as the Company continues to expand its international
operations, the Company may be paid in foreign currencies, and exposure to
losses in foreign currency transactions may increase. In addition, if the
relative value of the U.S. dollar in comparison to the Company's foreign
customers' currency should increase, the resulting effective price increase of
the Company's products to such foreign customers could result in decreased sales
which could have a material adverse effect on the Company's business, operating
results and financial condition.

 DEPENDENCE ON SUCCESS OF DTPI

     Under the terms of its existing contracts, DTPI is required to finance its
pro rata share of the build-out of the rural telephony networks for its
long-term service contracts in Mexico and Venezuela.



                                       17

<PAGE>   18


This will require substantial capital expenditures by DTPI, in addition to the
ongoing operating costs of running these rural telephony projects. Furthermore,
DTPI is investing in establishing a senior management team, whose
responsibilities will be to grow the business and to secure new contracts in
other countries. For DTPI to succeed, the Company will have to attract
substantial debt or equity financings either into DTPI directly, or into STM.
Also, due to the long term nature of the contracts that DTPI enters into, should
there be a breach of contract by either party to the contracts, or should the
customer be unable to pay the guaranteed revenues under the contracts, DTPI may
not be able to realize expected revenues and cash flows. In March 1998, the
Company completed a $10 million equity offering and is working with other
investors to secure additional financing. Should the Company not be able to
secure such financing, or should customer disputes or collectibility issues
arise, the Company may not be able to meet its business objectives for DTPI
which could have a significant impact on the size of the Company's business and
its level of profitability in the future.

 COMPETITION

     The market for the Company's products is intensely competitive. Many of the
companies that have developed competing technologies and market competing
products, including Hughes Network Systems and Scientific Atlanta, have
significantly greater financial, technical and marketing resources than the
Company. In addition, the Company's competitors in rural telephony have
substantially greater resources available to them to develop their products and
to establish strategic relationships in developing countries. There can be no
assurance that the Company's competitors will not succeed in developing
technologies and products that are more effective or less costly than any which
have been or are being developed by the Company or that would render the
Company's technologies or products obsolete or not competitive or that their
greater financial resources will not enable them to penetrate developing
countries more quickly than DTPI. The Company also competes against various
companies that offer communications network systems based on other technologies
(e.g., terrestrial lines and frame relay or radio and microwave transmission)
that in certain circumstances can be competitive in price and performance with
the Company's products. There can be no assurance that these or other
technologies will not capture a significant part of the markets in which the
Company's VSAT products compete.

 RAPID TECHNOLOGICAL CHANGE

        The technology underlying the Company's products and services is subject
to rapid change. The Company's success will depend in part upon its continuing
ability to respond quickly and successfully to technological advances by
developing and introducing new products. Most of the Company's competitors have
substantially greater financial and technical resources than the Company. If one
or more of the Company's competitors were to introduce competing products with
superior technological features, such introduction could have a material adverse
effect on the success of the Company's products.

DEPENDENCE ON PROPRIETARY RIGHTS; RISK OF INFRINGEMENT CLAIMS

     The Company relies on a combination of trade secrets, copyrights,
trademarks, service marks and contractual rights to protect its technology and
software. The Company attempts to protect its trade secrets and other
proprietary information through agreements with its customers, suppliers,
employees and consultants. Except for terrestrial and low cost telephony
products, the Company does not have patent protection on any aspect of its
technology or software. The Company believes that the improvement of existing
products, reliance upon trade secrets, copyrights and unpatented proprietary
know-how and the development of new products are generally as important as
patent protection in establishing and maintaining a competitive advantage
because, among other reasons, patents often provide only narrow



                                       18

<PAGE>   19
protection which may not provide a competitive advantage in areas of rapid
technological change. The use of trade secrets and copyrights will not
necessarily protect the Company from the use by other persons of its technology
or software, or technology or software that is similar to that which is embodied
in the Company's trade secrets or copyrights. There can be no assurance that
others will not be able to duplicate the Company's technology and software in
whole or in part. In addition, the laws of certain countries in which the
Company's products are or may be developed, manufactured or sold may not protect
the Company's products and intellectual property rights to the same extent as
the laws of the United States. The inability of the Company to protect its
intellectual property and proprietary technology could have a material adverse
effect on its business, operating results and financial condition. With respect
to the Company's venture into new fields such as terrestrial and low cost
telephony products, the Company believes that patent protection may be
necessary. Accordingly, the Company has applied for one patent and is in the
process of seeking additional patent protection with respect to this
application. In addition, as the number of patents, copyrights and other
intellectual property rights in the Company's industry increases, and as the
coverage of these rights and the functionality of the products of new markets
further overlap, the Company believes that its products may increasingly become
the subject of infringement claims. The Company may in the future be notified
that it is infringing upon certain intellectual property rights of others.
Although the Company has not received any such notification to date, and there
are no pending or threatened intellectual property lawsuits against the Company,
there can be no assurance that such litigation or infringement claims will not
occur in the future. Any such litigation or claims could result in substantial
costs and diversion of resources and could have a material adverse effect on the
Company's business, operating results and financial condition.

DEPENDENCE ON KEY PERSONNEL

     The Company's future performance is significantly dependent on the
continued active participation of Emil Youssefzadeh, the Company's founder,
Chief Executive Officer and President. However, in January 1998, the Company
announced a reorganization of the Company's businesses which will strengthen the
Company management and reduce the Company's dependence on Mr. Youssefzadeh.
However, should Mr. Youssefzadeh leave or otherwise become unavailable to the
Company, the Company's business, operating results and financial condition may
be materially adversely affected. The Company has obtained a "key man" life
insurance policy in the amount of $5,000,000 on the life of Mr. Youssefzadeh. In
addition to Mr. Youssefzadeh, the Company's future success depends upon its
ability to attract and retain additional highly qualified management and
technical personnel. The Company faces intense competition for qualified
personnel, and there can be no assurance that the Company will be able to
attract and retain such personnel.

ABILITY TO MANAGE GROWTH AND EXPANSION

     The Company has experienced growth over the past few years and aims to
continue to expand its operations both in the traditional, core manufacturing
business and through DTPI, its rural telephony service business. The management
of the Company's growth, if any, requires continued expansion of the Company's
operational and financial control systems, as well as a significant increase in
the Company's manufacturing, testing, quality control, delivery and service
operations. Although the Company has not experienced disruption in manufacturing
or shipment of its products in connection with its expansion to date, the
inability of the Company to meet its manufacturing and delivery commitments in a
timely manner (as a result of its expansion or otherwise) could result in the
loss of sales by the Company, expose it to contractual penalties, costs or
expenses and damage the Company's reputation in the marketplace. The Company's
inability to manage growth effectively could have a material adverse effect on
its business, operating results and financial condition and results of
operations. In addition, as a result of the planned expansion, the Company's
operating expenses have increased and the Company's operating results will be
adversely affected if sales do not increase as anticipated.



                                       19

<PAGE>   20

 DEPENDENCE ON KEY SUPPLIERS AND MANUFACTURERS

     Certain components used by the Company in its existing products are
purchased from single source suppliers and manufacturers. While the Company
maintains an inventory of components and believes that alternative suppliers and
manufacturers for all such components are currently available at reasonable
terms, an interruption in the delivery of these components may have a material
adverse effect on the Company. There can be no assurance as to when or whether
the Company would be able to locate any such alternative suppliers. Furthermore,
there can be no assurance that the Company will not encounter future component
shortages or other disruptions in the supply of materials. Delays associated
with raw materials or component shortages could have a material adverse effect
on the Company's business, operating results and financial condition.

POTENTIAL PRODUCT LIABILITY CLAIMS

     Although to date the Company has not experienced any product liability
claims, the sale and support of products by the Company involves the risk of
such claims. The Company maintains product liability insurance in amounts it
believes are customary for similar businesses in the industry; however, a
successful product liability claim brought against the Company, in excess of the
amount for which the Company is insured, or for which coverage is not provided
under the Company's insurance policies, could have a material adverse effect
upon the Company's business, financial condition and results of operations.

 CONTROL BY DIRECTORS, EXECUTIVE OFFICERS AND AFFILIATED ENTITIES

        As of September 30, 1997, the officers, directors, principal
stockholders and their affiliates owned approximately 54% of the outstanding
Common Stock. If such stockholders were to act in concert, they would be able to
control substantially all matters requiring approval by the stockholders of the
Company, including the election of directors. Such concentration of ownership
could discourage or prevent a change in control of the Company.
See "Principal Stockholders."

 POSSIBLE VOLATILITY OF STOCK PRICES

        The market prices for securities of technology companies, including the
Company, have been volatile. Quarter to quarter variations in operating results,
changes in earnings estimates by analysts, announcements of technological
innovations or new products by the Company or its competitors, announcements of
major contract awards and other events or factors may have a significant impact
on the market price of the Company's Common Stock. In addition, the securities
of many technology companies have experienced extreme price and volume
fluctuations, which have often been unrelated to the companies' operating
performance. These conditions may adversely affect the market price of the
Company's Common Stock.

 ANTI-TAKEOVER PROVISIONS

        The Company's Certificate of Incorporation provides for 5,000,000
authorized but unissued shares of Preferred Stock, the rights, preferences,
qualifications, limitations and restrictions of which may be fixed by the Board
of Directors without any further vote or action by the stockholders. The
Company's charter documents prescribe procedures for the nomination and election
of directors and limit the ability of stockholders to take actions by written
consent which could make it more difficult for stockholders to elect directors
or take other actions. Further, the Company's Bylaws include a "fair price
provision" which requires the affirmative vote of two-thirds of the outstanding
shares of



                                       20

<PAGE>   21

capital stock entitled to vote generally in the election of directors to approve
certain business combinations. In addition, the Company's stock option plan
provides for the acceleration of vesting of options granted under such plan in
the event of certain transactions which result in a change of control of the
Company. Further, Section 203 of the General Corporation Law of Delaware
prohibits the Company from engaging in certain business combinations with
interested stockholders. These provisions may have the effect of delaying or
preventing a change in control of the Company without action by the stockholders
and therefore could adversely affect the price of the Company's Common Stock.

CONCENTRATION OF CREDIT RISK

        The Company generates a substantial amount of its revenues from
individually significant orders, primarily on an international basis. These
sales are on a letter of credit or a similar guaranteed basis or on an open
account basis. Generally, credit on an open account basis is only extended to
customers with substantial financial resources or to public utilities that are
government owned in the country to which the product is shipped. There can be no
assurance, however, that these customers will not encounter liquidity problems
that could result in exceptional delays in the payment of or the inability to
pay, accounts receivable balances. In the event of such an occurrence, the
Company's financial condition and results of operations could be adversely
affected.

YEAR 2000 COMPLIANCE

        Many existing software programs use only two digits to identify the year
in the date field. If such programs are not corrected, date data concerning the
Year 2000 could cause many computer applications to fail, lock-up or generate
erroneous results. The Company is in the process of identifying and assessing
its mission-critical systems related to the Year 2000 and will commit the
resource necessary to resolve any potential Year 2000 issues. Although the
Company is addressing such issues in what it considers sufficient time prior to
century rollover, there can be no assurance that there will be no interruption
of operations or other limitations of system functionality, or that the Company
will not incur substantial costs to avoid such occurrences. The Company is
currently assessing the cost to remediate its Year 2000 issues. Although the
actual costs to remediate these issues is not yet fully known, based upon
information to date, it is expected that the remediation will not have a
material impact on the Company's financial condition or operating results.
However, failure to identify the mission-critical systems related to Year 2000
or failure to commit the resources necessary to resolve the Year 2000 issues on
a timely basis, could have a material impact on the Company's financial
condition or operating results.

ITEM 2 -  PROPERTIES

        The Company's principal offices are located in a 62,000 square foot
facility in Irvine, California, which houses all functions including
manufacturing, engineering, accounting, administration, marketing, sales, and
service. The Company purchased this facility on July 28, 1994 with cash reserves
and a purchase money promissory mortgage note (the "Mortgage Note") in the
amount of approximately $4.3 million. The Mortgage Note is secured by the
Company's land and building, accrues interest at 7% per annum, and requires
monthly principal and interest payments of approximately $28,700 which commenced
with the Company's occupancy in October 1994. The Mortgage Note is being
amortized over a thirty-year period and matures on September 1, 2009, at which
time all remaining principal and accrued interest is due.

ITEM 3 - LEGAL PROCEEDINGS

        From time to time, the Company is involved in litigation relating to
claims arising out of its operations in the normal course of business. As of
December 31, 1997, the Company was not engaged in any material legal proceedings
which the Company expects, individually or in the aggregate, will have a
material adverse effect on the Company's results of operations or its financial
condition.

ITEM 6 - SELECTED CONSOLIDATED FINANCIAL DATA

        The following selected consolidated financial data should be read in
conjunction with the consolidated financial statements and notes thereto
included elsewhere herein.

        Effective March 31, 1996, the Company sold all the outstanding common
stock of RF Microsystems ("RF") a wholly owned subsidiary for $2,926,000. This
sale qualified as a disposal of a segment of the business and accordingly prior
period financial statements have been reclassified to reflect the discontinuance
of this segment of the business. See note 4 to the consolidated financial
statements.

        In December 1997, the Company issued 480,000 shares of common stock in
exchange for all the outstanding common stock of Telecom International, Inc.
("TI"), a company that specializes in network systems integration. The
transaction was accounted for as a pooling of interests and accordingly, the
Company's financial statements have been restated to include the results of TI
for all applicable periods. TI commenced operations on June 12, 1995.

        The statement of operations data and income (loss) per share of common
stock with respect to the years ended December 31, 1997, 1996, and 1995 and the
balance sheet data at December 31, 1997 and 1996 are derived from audited
financial statements included elsewhere herein. The statement of operations data
and income (loss) per share of common stock for the year ended December 31, 1994
and 1993 and the balance sheet data at December 31, 1995, 1994, and 1993 are
derived from audited financial statements reclassified in connection with the
disposal discussed above.

     * The results for the fourth quarter of 1996 included charges of $5,200,000
which comprised reserves of $2,500,000, primarily for inventory obsolescence due
to the uncertainty about future revenues from the previous generation of the
Company's products, $1,000,000 for the settlement of contractual commitments and
claims, including $650,000 non-recurring engineering charges for a version of a
product that the Company does not expect to sell in significant quantities and
$1,700,000, primarily for customer concessions and allowances.

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

BACKGROUND

     STM is a developer, manufacturer, supplier and service provider of
wireless-based satellite communications infrastructure and user terminal
products, utilized for the creation of public and private telecommunications
networks. These networks support data, fax, voice and video communication and
are used to either bypass or extend terrestrial networks or provide a
communications infrastructure where a network does not currently exist. The
Company's product line is based on proprietary hardware and software and
primarily consists of two-way earth stations sometimes referred to as VSATs
(very small aperture terminals), associated infrastructure equipment and
software, transceivers, modems and other networking equipment. The Company
currently focuses its sales efforts on the international marketplace,
particularly developing countries because management believes that these areas
offer greater applications for the Company's technology, a higher growth
potential and more favorable competitive dynamics. Approximately 95% of the
Company's revenue is generated in the international market through foreign
distributors and sales representatives. The Company's customers include
government agencies, telephone companies, multi-location corporations and
others.

     During August, 1995 the Company purchased 72.5% of the outstanding common
stock and newly issued preferred stock of Telecom Multimedia Systems, Inc.
("TMSI") for $1,000,000 cash and 10,000 shares of the Company's common stock.
Arising from this transaction, the Company has approximately $617,000 of net
intangible assets and a balance of $259,000 due to the minority shareholders at
December 31, 1997.

     Effective March 31, 1996, the Company sold its RF subsidiary for $2,926,000
cash to REMEC, Inc. ("REMEC") Further, the Company also entered into a
Technology Purchase Agreement on March 31, 1996 with REMEC whereby the Company
sold certain of its technologies, which were not part of the RF business
segment, for $1,000,000 cash. See Note 4 to the consolidated financial
statements. In addition, the Company entered into a Development, Manufacturing
and Product Supply Agreement and a Manufacturing Supply Agreement which
established REMEC as the sole provider for certain components that are
incorporated into the Company's products utilizing the aforementioned
technologies. The Development, Manufacturing and Product Supply Agreement also
provides for joint development of other products by the Company and REMEC which
will require purchases of such products by the Company at specified levels and
market prices. See note 10 to the consolidated financial statements. The sale of
RF has been accounted as a discontinuation of a segment of the business and
prior period financial statements have been reclassified. Accordingly, the 1995
comparatives included herein have been revised to compare current year
continuing operations to prior periods continuing operations.

     In 1997, the Company was awarded, through its Direc-To-Phone International
subsidiary, two long-term service contracts to provide rural telephony services
in Mexico and Venezuela. DTPI was established in 1996 for the purpose of
offering fixed satellite telephony and advanced data services in emerging
markets. DTPI uses products manufactured by STM to enter into service agreements
with local partners for the purpose of generating long-term cash flows. These
service contracts will require significant up-front investment in equipment in
both countries. Such equipment will give rise to long-term cash flows from both
these contracts through revenue sharing arrangements with local in-country
service providers. In addition to the revenue sharing arrangement, there are
certain guaranteed monthly minimum revenues on a per line basis as well as one
time fees that are earned upon commissioning of each line. No revenues were
recognized under these contracts in 1997.



                                       26

<PAGE>   27

        In December 1997, the Company issued 480,000 shares of common stock in
exchange for all the outstanding common stock of Telecom International, Inc.
("TI"), a company that specializes in network systems integration. The
transaction was accounted for as a pooling of interests and accordingly, the
Company financial statements have been restated to include the results of TI for
all applicable periods.

RESULTS OF OPERATIONS

     The following table sets forth for the periods presented the percentages of
revenues represented by certain items in the Company's Statements of Operations
for the last three fiscal years. These percentages have been recalculated to
give effect to the discontinuation of the RF business segment in 1996 and the
acquisition of TI in 1997.

</TABLE>

RESULTS OF CONTINUING OPERATIONS

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     Revenues increased to $52,148,000 in 1997 from $38,294,000 in 1996, a 36.2%
increase, primarily as a result of the revenue earned under a $30 million
equipment supply contract with a customer in Thailand and an increase in
revenues earned by the Company's system integration business in 1997.
Approximately $30 million of revenues were recognized under this equipment



                                       27

<PAGE>   28
supply agreement and these revenues were recognized throughout the year
primarily in quarters 1 through 3 of 1997. The Company earned approximately
$12,500,000 from the same customer in Thailand in 1996 under another contract.
The Company's system integration business was acquired in 1997 when the Company
acquired TI in December 1997 in a transaction that was accounted for as a
pooling of interests and accordingly, the Company's financial statements were
restated to include the results of TI.

     The decline in service revenues to $2,324,000 in 1997 compared to
$2,904,000 in 1996 reflected a lower service content in 1997 revenues that can
occur, depending upon the nature of the contracts that the Company enters into
in any given period.

     The Company's focus on larger value sales can expose the Company to a
concentration of revenues to individual customers and in geographic regions
during particular fiscal periods. The $30 million equipment supply contract in
1997 increased this concentration of revenues. In recognition of this, the
Company's sales and marketing activities have been increased to broaden coverage
in the Company's selected markets. However, the Company will continue to take
advantage of individual significant contracts should they arise for both its
equipment supply and service business.

        Gross profits increased to 26.4% of revenues in 1997 from 24.4% in 1996.
Excluding approximately $2,500,000 of inventory obsolescence reserves included
in cost of revenues in 1996, the adjusted gross profit percentage for 1996 would
have been approximately 30.9%. The decline in the gross profit in 1997 reflects
a relatively lower gross profit percentage earned by the Company on the $30
million equipment supply sale to the customer in Thailand and a higher system
integration sales content at a lower gross profit percentage than the core
manufacturing business, in 1997 compared to 1996. 

     Selling, general and administrative expenses in 1997 were $9,589,000
compared to $9,688,000 in 1996. Measured as a percent of revenues, these
expenses decreased to 18.4% in 1997 as compared to 25.3% in 1996. The 1996
expense included approximately $1,700,000 associated with customer concessions
and allowances. Excluding this $1,700,000 from the 1996 expense, the adjusted
1996 selling, general and administrative expenses would have been $7,988,000 or
20.9% of revenues, compared to 18.4% for 1997. The decrease in percentage terms
in 1997 reflected the relatively fixed nature of certain costs that did not
increase in proportion to the increase in revenues. The dollar increase in
selling, general and administrative expenses in 1997 compared to 1996 (adjusted
for the $1,700,000 previously discussed) reflected increased costs, primarily to
support the growth in revenue in both the core manufacturing business and the
system integration business.

     Research and development expenses were $6,387,000 in 1997 as compared to
$6,895,000 in 1996. Measured as a percent of revenues, these expenses decreased
to 12.2% in 1997 as compared to 18.0% in 1996. Adjusting the 1996 expense for
$1,000,000 of non-recurring engineering charges associated with a product that
the Company does not expect to sell in significant numbers and was fully
expensed in 1996, research and development expenses in 1997 would have increased
by $492,000, or 8.3% over the comparable 1996 expense. This dollar increase was
due to planned expenditures for personnel and outside services in support of the
Company's continuing new product development efforts. In percentage terms, the
adjusted 1996 expenses represented 15.4% of revenues. The decrease in percentage
terms in 1997 was due to the relatively fixed nature of certain costs that did
not increase in proportion to the increase in revenues.

     The income tax benefit for 1997 was $306,000 as compared to $1,907,000 in
1996. The decrease in the income tax benefit in 1997 compared to 1996 related to
a lower loss in 1997 compared to 1996 and the Company reviewing the level of
deferred tax assets existing at December 31, 1997 for



                                       28

<PAGE>   29
realizability due to the Company incurring losses for both 1997 and 1996.
Management believes that its is more likely than not that the Company will
realize the benefit of its existing timing differences, however, there can be no
assurance that the Company will generate any specific level of income in future
years.

     The minority interest of $126,000 and $67,000 in 1997 and 1996
respectively, represented the share of the losses of TMSI attributable to the
minority shareholders.

     The income from discontinued operations and gain on sale, net of income
taxes in 1996 of $88,000 related to the disposal of RF.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     Revenues for 1996 were $38,294,000 compared with $31,881,000 for 1995, a
20.1% increase. The increase in revenues in 1996 compared to 1995 related to
increased sales to certain key customers and increased sales in the system
integration business. Revenues in 1996 included significant sales to customers
in Thailand, the Netherlands, India, Brazil and the Philippines.

     Service revenues for 1996 were $2,904,000 compared to $3,611,000 in 1995, a
decrease of 19.6%. This decrease in 1996 was primarily the result of the absence
of a 1995 management services contract for the provision of services to a
Malaysian customer.

     The gross profit for 1996 was $9,328,000 compared to $10,990,000 for 1995,
representing gross profit percentages of 24.4% and 34.5% for 1996 and 1995,
respectively. The decrease in the gross profit to 24.4% in 1996 was primarily
the result of the recognition of inventory obsolescence reserves which reflected
the Company's decision to focus on the high volume public telephony business
represented by the DAMA product and the higher system integration sales content
in 1996 compared to 1995, at a lower gross profit percentage than the core
manufacturing business.

     Selling, general and administrative expenses were $9,688,000 in 1996
compared to $6,315,000 in 1995, representing 25.3% and 19.8% of revenues for
1996 and 1995, respectively. The increase of $3,373,000 in 1996 comprised
increased selling costs of approximately $1,700,000 attributable to reserves
established in 1996 to recognize customer concessions and allowances and
increased costs incurred to support the growth in revenues in both the core
manufacturing business and the system integration business. Excluding the
$1,700,000 reserves established, the selling, general and administrative
expenses would have represented 20.9% of revenues in 1996 compared to 19.8% of
revenues in 1995.

     Research and development costs for 1996 were $6,895,000 compared to
$3,677,000 in 1995, representing 18.0% and 11.6% of revenues for 1996 and 1995,
respectively. Approximately $1.0 million of the increase was attributable to the
Company recognizing its full obligation for certain non-recurring engineering
charges associated with a product that the Company does not expect to sell in
significant numbers. The remaining increase related to planned investment in
personnel and outside services, both in the Company and its TMSI subsidiary.

     Interest income for 1996 was $982,000 compared to $702,000 for 1995. The
increase reflected higher investment income generated from the Company's excess
cash. Interest expense for 1996 was $764,000 compared with $379,000 for 1995.
The increase reflected a higher level of short term borrowings as a result of
draw downs under the Company's credit facilities.

     In 1996, the Company had an income tax benefit of $1,907,000 compared to an
income tax



                                       29

<PAGE>   30

provision of $347,000 in 1996. The 1996 benefit reflected losses incurred in
1996 as compared with income for 1995. The benefit in 1996 primarily related to
the effects of current year net operating losses on deferred income taxes.

     The minority interest of $67,000 and $82,000 for 1996 and 1995
respectively, represented the share of losses of TMSI attributable to the
minority shareholders.

     The income from discontinued operations and gain on sale in 1996, net of
income taxes related to RF and represented in 1996, the net income from
operations for the period January 1, 1996 to March 31, 1996 and the gain on the
sale, while in 1995 it represented the results of operations for the year 1995.

RESULTS OF DISCONTINUED OPERATIONS

     For 1996 and 1995, revenues for RF were $1,216,000 and $5,339,000, net
income (loss) was $37,000 and $333,000, respectively, and the gain on sale in
1996 was $51,000.

LIQUIDITY AND CAPITAL RESOURCES

     In 1997, the Company had positive cash flows from continuing operations of
$944,000 compared to negative cash flows of $2,378,000 in 1996. This improved
cash flow from continuing operations in 1997 compared to 1996, was primarily a
result of lower net losses for the year, decreases in accounts receivable, and
increases in accounts payable, partially offset by increases in inventories.

     In 1997, the Company used $9,940,000 in investing activities, compared with
$2,332,000 provided by investing activities in 1996. The significant changes in
1997 compared to 1996 primarily relate to approximately $7,800,000 of property,
plant and equipment that was capitalized in the fourth quarter of 1997 in
connection with the Company's long-term service contracts in Mexico and
Venezuela and the absence of the proceeds of the disposal of RF, which occurred
in 1996.

     In 1997, net cash provided by financing activities was $2,638,000, compared
to $4,873,000 in 1996, primarily comprising in 1997, net proceeds received under
credit facilities of $1,344,000 and proceeds from the issuance of common stock
of $821,000 (mainly arising from the exercise of stock options). In 1996, the
net proceeds received under credit facilities was $5,157,000.

     Overall, the Company's cash, cash equivalents and short-term investments
totaled $8,622,000 at December 31, 1997 compared to $14,962,000 at December 31,
1996.

     The Company has lines of credit from three separate banks totaling
$13,350,000. Availability under these lines of credit at December 31, 1997 was
approximately $13,000,000, of which $7,900,000 was drawn down.

     In connection with the award of certain long-term service contracts in
Mexico and Venezuela, and due to the capital intensive nature of these
contracts, and other contracts that DTPI may be awarded in the future, the
Company is reviewing financing alternatives to enable it to pursue these
business opportunities in the most beneficial manner. However, there can be no
assurance that such financing will be available, nor that such financing will be
available on terms acceptable to the Company. However, subsequent to December
31, 1997, the Company and DTPI completed a $10 million equity offering with
Pequot Private Equity Fund L.P., the private investment vehicle of
Dawson-Samberg Capital Management, Inc. for newly issued shares in both STM and
DTPI.

     Management expects to have sufficient cash generated through operations,
through availability under existing lines of credit and through other sources to
meet its anticipated cash requirements for the next 12 months.

     In September, 1994 the Company's Board of Directors authorized a stock
repurchase program whereby the Company may repurchase, in the open market, up to
10% of its shares outstanding, at times and prices to be determined by the
Board. The repurchased shares would be used for potential future acquisitions
and for exercises under the Company's stock option plans. The Company has not
repurchased any shares to date nor does it have any present commitments to
repurchase shares at this time.

NEW ACCOUNTING STANDARDS

     In June 1997, the Financial Accounting Standards Board issued SFAS Nos. 130
and 131, Reporting Comprehensive Income ("SFAS 130") and Disclosures about
Segments of an Enterprise and Related Information ("SFAS 131") respectively
(collectively, the "Statements"). The Statements are effective for fiscal years
beginning after December 15, 1997. SFAS 130 establishes standards for reporting
of comprehensive income and its components in annual financial statements. SFAS
131 establishes standards for reporting financial and descriptive information
about an enterprise's operating segments in its annual financial statements and
selected segment information in interim financial reports. Reclassification or
restatement of comparative financial statements or financial information for
earlier periods is required upon adoption of SFAS 130 and SFAS 131,
respectively. Application of the Statements' requirements is not expected to
have a material impact on the Company's consolidated financial position, results
of operations or loss per share as currently reported.

YEAR 2000 COMPLIANCE

     Many existing software programs use only two digits to identify the year in
the date field. If such programs are not corrected, date data concerning the
Year 2000 could cause many computer applications to fail, lock-up or generate
erroneous results.

     The Company is in the process of identifying and assessing its
mission-critical systems related to the Year 2000 and will commit the resources
necessary to resolve any potential Year 2000 issues. Although the Company is
addressing such issues in what it considers is sufficient time prior to century
rollover, there can be no assurance that there will be no interruption of
operations or other limitations of system functionality, or that the Company
will not incur substantial costs to avoid such occurrences.

     The Company is currently assessing the cost to remediate its Year 2000
issues. Although the actual cost to remediate these issues is not yet fully
known, based upon information to date, it is expected that the remediation will
not have a material impact on the Company's financial condition or operating
results.

also audited the financial statement schedule as listed in the accompanying
index. These consolidated financial statements and financial statement schedule
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements and financial
statement schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of STM Wireless, Inc.
and subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 31, 1997, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic consolidated financial statements taken as a
whole, presents fairly, in all material respects, the information set forth
therein.

                   Notes to Consolidated Financial Statements
                  Years ended December 31, 1997, 1996 and 1995

(1)     Description of the Company

        STM Wireless, Inc. (the "Company" or "STM") is a developer, manufacturer
        and provider of wireless-based satellite communications infrastructure
        and user terminal products utilized in public and private
        telecommunications networks. These networks support data, fax, voice and
        video communication and are used to either bypass or extend terrestrial
        networks or provide a communications infrastructure where a network does
        not currently exist. The Company's product line is based on proprietary
        hardware and software and primarily consists of two-way earth stations
        sometimes referred to as VSATs (very small aperture terminals),
        associated infrastructure equipment and software, transceivers, modems
        and other networking equipment. The Company currently focuses its sales
        efforts on the international marketplace, particularly developing
        countries. The Company's subsidiary, Direc-To-Phone International, Inc.
        ("DTPI"), will provide fixed telephony services in international
        markets.

(2)     Summary of Significant Accounting Policies

        Principles of Consolidation

        The consolidated financial statements include the accounts of the
        Company and its majority and wholly-owned subsidiaries including DTPI,
        the Company's fixed telephony service subsidiary and Telecom
        International, Inc. ("TI"), the Company's system integration subsidiary
        (see note 3). The minority interest relates to Telecom Multimedia
        Systems, Inc., ("TMSI"), the Company's internet telephony and voice over
        IP solutions subsidiary (see note 3). All significant intercompany
        balances and transactions have been eliminated in consolidation.

        Use of Estimates

        The financial statements have been prepared in conformity with generally
        accepted accounting principles. In preparing the financial statements,
        management is required to make estimates and assumptions that affect the
        reported amounts of assets and liabilities and disclosure of contingent
        assets and liabilities as of the dates of the balance sheets and
        revenues and expenses for the periods. Actual results could differ
        significantly from those estimates.

        Revenue Recognition

        Sales of the Company's communications products and related installed
        software are generally recognized upon shipment. Sales of the Company's
        products to distributors are normally not subject to right of return.

        Revenues from contract services are earned under cost reimbursement and
        fixed price type contracts. Revenues from contracts are recognized under
        the percentage-of-completion method, whereby contract costs are expensed
        as incurred and revenues are recorded based on the ratio of costs
        incurred to total estimated costs at completion. There were no costs and
        estimated earnings in excess of billings on contracts under the
        percentage of completion method at December 31, 1997, and 1996
        respectively. If the estimate of total contract costs



                                       39

<PAGE>   40

        results in a loss, a provision is made currently for the total
        anticipated loss.

        The Company generally warrants its products to be free from defects for
        a period of one year from shipment. Estimated warranty expense is
        recognized upon shipment of equipment.

        Cash Equivalents

        Cash equivalents are highly liquid investments which are readily
        convertible into known amounts of cash and have original maturities of
        three months or less, consisting primarily of cash, certificates of
        deposit and other money market instruments.

        Short-term Investments

        The Company's short-term investments consisting of certificates of
        deposits, various U.S. government securities, and others have been
        classified as "available for sale" and have original maturities between
        90 and 360 days. As of December 31, 1997 and 1996 the fair market value
        of these securities approximates cost.

        Inventories

        Inventories are stated at the lower of cost (first-in, first-out method)
        or market and consist of the following:

</TABLE>

        Certain components used by the Company in its existing products are
        purchased from single source suppliers and manufacturers. While the
        Company maintains an inventory of components and believes that
        alternative suppliers and manufacturers for all such components are
        available at reasonable terms, an interruption in the delivery of these
        components may have a material adverse effect on the Company.

        In December 1996, the Company increased its inventory reserves by
        approximately $2,500,000 to recognize the increased risk of obsolescence
        associated with previous generations of the Company's products and to
        reflect the Company's present focus on the high volume public telephony
        business. These reserves are substantially intact at December 31, 1997.

        Property, Plant and Equipment

        Property, plant and equipment is recorded at cost and depreciated on a
        straight-line basis over the estimated useful lives of the assets.
        Buildings are depreciated over 30 years. Satellite equipment, other
        equipment and furniture and fixtures are depreciated over 3-5 years.
        Assets used for long-term service contracts will be depreciated
        commencing when the asset is placed in service, over the shorter of
        their estimated useful lives or the lives of the contracts to which they
        relate. Leasehold improvements are amortized over the shorter of their
        estimated useful lives or the



                                       40

<PAGE>   41

        term of the lease.

        Long-Term Receivables

        Long-term receivables are recorded at cost, less the related allowance
        for impaired notes receivable. Management, considering current
        information and events regarding the borrowers' ability to repay their
        obligations, considers a note to be impaired when it is probable that
        the Company will be unable to collect all amounts due according to the
        contractual terms of the note agreement. When a loan is considered to be
        impaired, the amount of the impairment is measured based on the present
        value of expected future cash flows discounted at the note's effective
        interest rate. Impairment losses are included in the allowance for
        doubtful accounts through a charge to bad debt expense. Cash receipts on
        impaired notes receivable are applied to reduce the principal amount of
        such notes until the principal has been recovered and are recognized as
        interest income, thereafter. As of December 31, 1997 and 1996, the
        Company has not considered an allowance for impaired notes receivable to
        be necessary.

        Fair Value of Financial Instruments

        SFAS No. 107, "Disclosure about Fair Value of Financial Instruments,"
        requires entities to disclose the fair value of financial instruments,
        both assets and liabilities recognized and not recognized on the balance
        sheet, for which it is practicable to estimate fair value. SFAS No. 107
        defines fair value of a financial instrument as the amount at which the
        instrument could be exchanged in a current transaction between willing
        parties.

        As of December 31, 1997 and 1996, the carrying value of cash and cash
        equivalents, accounts receivable, accounts payable, accrued liabilities
        and income taxes payable approximate fair value due to the short term
        nature of such instruments. The carrying value of short-term investments
        approximate fair value based on quoted market prices for those or
        similar investments. The fair value of all debt and long-term
        receivables approximate fair value as the related interest rates
        approximate rates currently available to/from the Company.

        Research and Development

        All research and development costs are charged to expense as incurred
        and primarily consist of salaries and applicable overhead expenses of
        employees directly involved in the design and implementation of the
        satellite network hardware and software and certain third party outside
        service costs.

        Income Taxes

        Income taxes are accounted for under the asset and liability method.
        This method generally provides that deferred tax assets and liabilities
        be recognized for temporary differences between the financial reporting
        basis and the tax basis of the Company's assets and liabilities and
        expected benefits of utilizing net operating loss ("NOL") carryforwards.
        The Company records a valuation allowance for certain temporary
        differences for which it is not more likely than not that it will
        realize future tax benefits. The impact on deferred taxes of changes in
        tax rates and laws, if any, are applied to the years during which
        temporary differences are expected to be settled and reflected in the
        financial statements in the period of enactment.



                                       41

<PAGE>   42



        Stock Options Plans

        Prior to January 1, 1996, the Company accounted for its stock option
        plans in accordance with the provisions of the Accounting Principles
        Board ("APB") Opinion 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 January 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
        (loss) and pro forma net income (loss) 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.

        Impairment of Long-lived assets and Long-lived assets to be disposed of

        The Company reviews long-lived assets and certain identifiable
        intangibles for impairment whenever events or changes in circumstances
        indicate that the carrying amount of an asset may not be recoverable.
        Recoverability of assets to be held and used is measured by a comparison
        of the carrying amount of an asset to future net cash flows expected to
        be generated by the asset. If such assets are considered to be impaired,
        the impairment to be recognized is measured by the amount by which the
        carrying amount of the assets exceed the fair value of the assets.

        Income (Loss) per Share of Common Stock

        Effective December 31, 1997, the Company adopted SFAS No. 128, "Earnings
        per Share". This statement replaces the previously reported primary and
        fully diluted earnings per share with basic and diluted earnings per
        share. Unlike primary earnings per share, basic earnings per share
        excludes any dilutive effects of options. Diluted earnings per share is
        very similar to the previously reported fully diluted earnings per
        share. All income and loss per share amounts for all periods presented
        have been restated to conform to the SFAS No. 128 requirements (see note
        14).

        New Accounting Pronouncements

        In June 1997, the Financial Accounting Standards Board issued SFAS Nos.
        130 and 131, "Reporting Comprehensive Income" ("SFAS 131") and
        "Disclosures about Segments of an Enterprise and Related Information"
        ("SFAS 131"), respectively (collectively, the "Statements"). The
        Statements are effective for fiscal years beginning after December 15,
        1997. SFAS 130 established standards for reporting of comprehensive
        income and its components in annual financial statements. SFAS 131
        establishes standards for reporting financial and descriptive
        information about an enterprise's operating segments in its annual
        financial statements and selected segment information in interim
        financial reports. Reclassification or restatement of comparative
        financial statements or financial information for earlier periods is
        required upon adoption of SFAS 130 and SFAS 131, respectively.
        Application of the Statements' requirements is not expected to have a
        material impact on the Company's consolidated financial position,
        results of operations or income (loss) per share data as currently
        reported.

        Reclassifications

        Certain reclassifications have been made to the 1996 and 1995
        consolidated financial statements to conform to the 1997 presentation.

 (3)    Acquisitions

        Telecom International, Inc.

        On December 12, 1997, the Company issued 480,000 shares of its common
        stock in exchange for all of the outstanding common stock of TI. TI is a
        system integrator and installer of large satellite terminals used in
        rural telephony and enterprise networks. The merger has been accounted
        for as a pooling of interests and accordingly, all prior period
        financial statements have been restated as if the merger took place at
        the beginning of such periods.

        TI was a Subchapter S corporation for income tax purposes from its
        inception on June 12, 1995, to December 31, 1995, and therefore did not
        pay U.S. federal income taxes. Effective January 1, 1996, TI elected C
        corporation status for federal income tax reporting purposes. TI will be
        included in the Company's U.S. consolidated tax return effective
        December 12, 1997 (the date of acquisition).

        Results of operations for the periods prior to the merger with TI are as
        follows:

        Telecom Multimedia Systems, Inc.

        In August 1995, the Company purchased 72.5% of the outstanding common
        stock and newly issued preferred stock of Telecom Multimedia Systems,
        Inc. ("TMSI") for $1,000,000 cash and 10,000 shares of the Company's
        common stock valued at $18.75 per share. TMSI develops and markets
        advanced Internet telephony products, leveraging its expertise in
        digital signal processing solutions to provide low delay, high quality,
        voice over IP solutions. The acquisition of TMSI was accounted for as a
        purchase. Accordingly, the purchase price was allocated to the net
        assets acquired based upon their estimated fair market values. The
        accompanying consolidated statements of income reflect the operations of
        TMSI since the effective date of the acquisition.

(4)     Discontinued Operations

        Effective March 31, 1996, the Company sold its RF Microsystems ("RF")
        subsidiary to REMEC, Inc.("REMEC") for cash of $2,926,000. RF designed
        and manufactured microwave systems and components and provided technical
        support under government contracts. Such disposition has been accounted
        for as a disposal of a segment of a business and prior period financial
        statements have been reclassified to reflect discontinuance of this
        business segment.

        During the three-months ended March 31, 1996 and the year ended December
        1995, RF had revenues of $1,216,000, and $5,339,000 respectively and net
        income of $37,000, and $333,000, respectively. Additionally, the Company
        recorded a gain on the sale of RF of $51,000 which is included in income
        from discontinued operations and gain on sale in 1996, net of income
        taxes in the accompanying consolidated statement of operations for 1996.

        In 1984, the Company adopted an Incentive Stock Option Plan ("ISO") (the
        "1984 Plan") to reward the performance and contributions of eligible
        employees. Options were granted at the discretion of the Board of
        Directors to selected employees to purchase shares of the Company's
        common stock at fair market value at the date of grant. Options
        generally became exercisable in annual installments beginning one year
        after the date of grant. All options expired ten years after the date of
        grant. No more than 498,000 shares were to be issued under the 1984
        Plan. Also, the Company from time to time granted non qualified stock
        options to directors, consultants and officers. These options were
        granted and vested based upon terms decided upon by the Board of
        Directors. At December 31, 1996, all options to purchase shares had been
        exercised. The 1984 Plan was terminated by the Board of Directors in
        February 1992.

        In January 1992, the Company adopted the Incentive Stock Option, Non
        qualified Stock Option and Restricted Stock Purchase Plan - 1992 (the
        "1992 Plan"). The 1992 Plan was amended by the Board of Directors in
        both 1995 and 1994 to increase the number of stock options available for
        grant by 500,000. The 1992 Plan now provides for the grant by the
        Company of options and/or rights to purchase up to an aggregate of
        850,000 shares of common stock.

        In October 1994, the Company's Board of Directors adopted the Satellite
        Technology Management, Inc. 1994 Option Plan for Non-Employee Directors
        (the "1994 Plan"). The 1994 Plan was approved by the Company's
        stockholders in July 1995. The 1994 Plan provides for the grant by the
        Company of options to purchase up to 250,000 shares of common stock to
        non-employee members of the Company's Board of directors who are neither
        employees nor paid consultants of the Company.

        As explained in Note 2, the Company applies APB Opinion No. 25 in
        accounting for its stock option plans. Accordingly, no compensation cost
        has been recognized for the Company's plans in the consolidated
        financial statements. Had the Company determined compensation cost based
        on the fair value at the grant date for its stock options under SFAS No.
        123, the Company's basic and diluted net income (loss) and net income
        (loss) per share would have been adjusted to the following pro forma
        amounts:

       Compensation cost of $1,237,000, $750,000, and $395,000 for 1997, 1996
       and 1995 respectively, was determined using the Black-Scholes option
       pricing model with the following weighted average assumptions for grants
       in 1997, 1996, and 1995 -- risk free interest rate of 6.33%, 6.21%, and
       6.31%, respectively, an expected life of five years and an expected
       volatility rate of 68.3%, 55.8% and 55.8%, respectively.

       Pro forma net income (loss) and pro forma income (loss) per share
       reflects only options granted in 1997, 1996 and 1995. Therefore, the full
       impact of calculating compensation cost for stock options under SFAS 123
       is not reflected in the net income (loss) presented above because
       compensation cost is reflected over the options' vesting period of five
       years and compensation cost for options granted prior to January 1, 1995
       is not considered.

        Common stock received through the exercise of non-qualified stock
        options or incentive stock options which are sold by the optionee within
        two years of grant or one year of exercise result in a tax deduction for
        the Company equivalent to the taxable gain recognized by the optionee.
        For financial reporting purposes, the tax effect of this deduction is
        accounted for as a credit to common stock rather than as a reduction of
        income tax expense. Such optionee sales resulted in a tax benefit to the
        Company of approximately $115,000 during 1995.

        At December 31, 1997, the range of exercise prices and weighted -
        average remaining contractual life of outstanding options under the
        Company's stock option plans were $ 3.88 to $14.00 and 8.45 years,
        respectively.

    (1)    The Company implemented an option cancellation/regrant program for
           directors, executive officers, and all other employees holding stock
           options with an exercise price per share in excess of the market
           value of STM Wireless, Inc. common stock at the time the
           cancellation/regrant occurred. Optionees who accepted the repricing
           agreed that the regranted options would vest ratably over a period
           one year longer than the vesting period of the options cancelled. The
           program was effected on March 20, 1997 and 332,850 options in excess
           of $7.125 per share were cancelled and 332,850 new options were
           granted at an exercise price of $7.125, the fair value on the date of
           grant.

        Stock Purchase Warrants

        In connection with the Company's initial public offering of common stock
        (the "IPO") in 1992, the Underwriter acquired warrants from the Company
        to purchase up to 162,500 shares of Common Stock at an exercise price of
        $15.00 per share. The warrants were exercisable for



                                       49

<PAGE>   50

        a period of four years beginning one year after the date of the IPO and
        expired in 1997.

        In May 1993, in connection with a settlement agreement, a warrant to
        purchase 7,500 shares of Common Stock at an exercise price of $10.00 per
        share was granted. The warrant was fully exercised during 1995.

(10)    Commitments and Contingencies

        Purchase Commitments

        In connection with the sale of RF (see note 4), the Company entered into
        purchase commitments with REMEC to purchase components that are
        incorporated into certain of the Company's products.

        Under the Manufacturing and Product Supply Agreement dated April 30,
        1996 the Company entered into a two year agreement to purchase a minimum
        of $9,375,000 of product for which there is no remaining obligation at
        December 31, 1997.

        Under the Development, Manufacturing and Product Supply Agreement, dated
        April 30,1996 as amended November 1, 1996, the Company entered into a
        three year agreement to undertake the joint development of two products.
        The agreement requires the Company to reimburse REMEC for non-recurring
        engineering expenses for the development of the products up to
        $1,250,000 and to purchase products up to approximately $18,000,000. STM
        will have title to and ownership of the design of the products and will
        have exclusive rights to the sale of the products. The three year period
        commences with the production of the first unit, which is expected to be
        in 1998. Should the Company fail to purchase the minimum requirement of
        the products or elects to terminate the agreement, the Company will be
        required to pay REMEC up to $2,475,000. To date, the Company has
        expensed $1,250,000 for non-recurring engineering expenses of which
        $250,000 and $1,000,000 was recognized in 1997 and 1996, respectively.

        While management believes that none of these purchase commitments are in
        excess of requirements and all purchases will be used to fulfill
        customer orders and orders in connection with the Company's long-term
        contracts in Mexico and Venezuela, in the normal course of business,
        there can be no assurance that the Company will generate a future level
        of revenues sufficient to satisfy its purchase commitments.

        Litigation

        The Company is involved as both plaintiff and defendant in various
        claims and legal actions arising in the ordinary course of business. In
        the opinion of management, the ultimate disposition of these matters
        will not have a material adverse effect on the Company's financial
        position or results of operation.

        Contingency

        A wholly-owned subsidiary of the Company, the net assets of which are
        insignificant, is contingently liable under a $1,592,000 standby letter
        of credit as security for a non-recourse bank loan made to the Company
        in a back-to-back lending arrangement. The total facility available to
        the Company is $3,600,000. Under the arrangement, a customer pledged
        cash balances and cash flows sufficient to repay bank indebtedness used
        by that customer to fund



                                       50

<PAGE>   51

        purchases from the subsidiary. The customer's bank indebtedness was
        arranged under terms duplicate to, and is being used to service, the
        non-recourse bank loan. The Company has determined that the customer's
        cash security is sufficient to repay the bank's loan and that it is
        remote that the standby letter of credit will be negotiated to repay any
        indebtedness owed by the customer. Accordingly, the back-to-back loans
        have been offset by the Company.

        In addition, the Company is contingently liable for standby letters of
        credit for a $120,000 bid bond issued in connection with a customer
        tender document.

(11)    Income Taxes

        The components of income tax benefit (expense) consists of the

</TABLE>

        The valuation allowance established against deferred tax assets was
        increased by $22,000 in 1997. In order to fully realize the net deferred
        tax asset of $3,132,000 at December 31, 1997, the Company must generate
        net taxable income during the carryforward period of approximately
        $7,830,000. Additionally, in order to utilize the foreign tax credit
        carryforward the Company must have sufficient foreign source income.
        Management believes it is more likely than not that the Company will
        realize the benefit of the existing net deferred tax assets as of
        December 31, 1997 and that the existing net deductible temporary
        differences will reverse during periods in which the Company generates
        net taxable income; however, there can be no assurance that the Company
        will generate any earnings or any specific level of continuing earnings
        in future years.

        At December 31, 1997, the Company had available research and development
        credit carryforwards of approximately $450,000 which expire in 2001 to
        2010, as well as $95,000 of alternative minimum tax credits which
        carryforward indefinitely.

        The Company has not provided for U.S. Federal income and foreign
        withholding taxes on its foreign subsidiaries' undistributed earnings as
        of December 31, 1997, because such earnings are intended to be
        reinvested indefinitely. If these earnings are distributed in the
        future, foreign tax credits would become available under U.S. law to
        reduce the effect on the Company's overall tax liability.

</TABLE>

        The Company generates a substantial amount of its revenues from
        individually significant orders, primarily on an international basis to
        both developed and developing countries. This can give rise to a
        concentration of revenues and credit risks to individual customers and
        in geographic regions.

        No revenues were recognized in 1997, for certain long-term service
        contracts in Mexico and Venezuela that were awarded to DTPI in 1997.

        In 1997, the Company generated revenues from approximately 45 customers
        in 25 countries (including the United States) compared to approximately
        58 customers in 26 countries in 1996.

        While in an individual year a customer can represent a significant
        proportion of the revenues for that year, the Company does not generate
        a significant level of on-going repeat revenues for any individual
        customer. The Company's revenues, in general, in any given year
        represent new projects, to new or existing customers in new or existing
        geographic regions.

        However, the Company has generated approximately 68%, 53% and 40% of its
        revenue in Asia in 1997, 1996 and 1995, respectively. In addition, the
        Company has generated approximately 59%, 33% and 6% of revenues from one
        Asian customer in 1997, 1996 and 1995, respectively. The recent
        deterioration of the Asian economies may impact the level of revenues
        that the Company may earn in future years.

        To date, the Company has been successful in generating sales to new
        customers, however, there can be no assurance that the Company will
        generate any revenues or any specific level of continuing revenues in
        future years.

        Asia

        Within the Asian region there were sales to one customer in Thailand for
        approximately $30,600,000, 12,500,000 and approximately $2,050,000 in
        1997, 1996 and 1995, respectively. At December 31, 1996 and 1995, the
        accounts receivable balances for this customer were approximately
        $1,476,000 and $211,000, respectively. There was no balance receivable
        from this customer at December 31, 1997. In addition, sales in India in
        1996 and 1995 were approximately $4,350,000 and $5,100,000 respectively.
        The sales in 1996 were to six customers while in 1995 there were sales
        to two customers of which approximately $4,650,000 was to one customer.

        For 1995, there were sales to a single Malaysian customer having as a
        director and major shareholder the Chairman of the Board of Directors
        and major shareholder of Berjaya. Berjaya owns 1,221,294 shares (17.1%)
        of the Company's common stock. Revenues in 1995 for this customer
        include product hardware and software of $4,698,000 and engineering,
        project management and contract negotiation fees (services) of
        $1,175,000. There were no sales to this customer in 1996 and 1997.

        Latin and South America

        Sales in Latin and South America in 1997 were to 17 customers. There was
        only one significant sale to a customer in Venezuela for approximately
        $3,300,000 in 1997. At December 31, 1997, the accounts receivable
        balance for this customer was approximately $2,200,000. The Company and
        this customer entered into a joint venture agreement in December 1997,
        to provide long-term fixed telephony services in Venezuela. Sales in
        Brazil in 1997, 1996 and 1995 were approximately $1,313,000, $2,737,000
        and $4,084,000, respectively. Sales in 1996 are net of a 1995 sale of
        $2,132,000 that was reversed in 1996 as a result of the Company's
        decision to rescind the sale and refund the original deposit made by the
        customer, due to changed economic and regulatory conditions in Brazil.

        Europe

        Sales in Europe in 1997 were to 5 customers. The only significant sale
        in 1997 was to a customer in Poland for approximately $2,500,000. The
        accounts receivable balance for this customer was approximately
        $1,100,000 at December 31, 1997. There were no sales to this customer in
        1996 or 1995. In Holland, sales to one customer were approximately
        $600,000, $3,800,000 and $1,680,000 in 1997, 1996 and 1995,
        respectively. In Spain, sales to one customer were approximately
        $560,000, $660,000 and $6,450,000 in 1997, 1996 and 1995, respectively.

        Sales in Italy amounting to approximately $2,335,000 in 1996 were
        primarily to a distributor whose Former Chief Executive Officer was a
        member of the Company's Board of Directors from November 1991 until
        April 1993.

        North America

        Sales in North America have been reclassified in 1996 and 1995 for the
        sale of RF in 1996 which has been treated as a discontinuation of a
        segment of the business. Sales by RF in 1996 and 1995 were $1,216,000
        and $5,339,000, respectively and all sales were to customers in North
        America.

        Sales are, in general, to customers with substantial financial resources
        or to public utilities that are government owned in the country to which
        the product is shipped.

        The Company sells substantially all of its products and services
        internationally both on a letter of credit or similar guaranteed basis,
        whereby customers post secured letters of credit to assure collection
        of receivables, and on an open account basis. At December 31, 1997 and
        1996, the Company had five customers, which accounted for approximately
        $5,835,000 and $6,111,000, respectively of total accounts receivable, of
        which 68% and 63%, respectively were on a letter of credit basis.

        In 1996, the Company established approximately $1,700,000 in accounts
        receivable



                                       54

<PAGE>   55

       
        allowances, primarily for customer concessions and allowances that were
        estimated to be required. Approximately $1,100,000 of accounts
        receivable were written-off against these allowances in 1997.

(13)    Employee Benefits

        Effective September 1991, the Company adopted a defined contribution
        401(k) savings and investment plan. The Company's contributions to the
        plan are determined at the discretion of the Board of Directors. During
        1997, 1996 and 1995, the Company made no contributions to the Plan.

        In 1996, TI established a separate, defined contribution 401(k) savings
        and investment plan for all its eligible employees. Under the plan, the
        Company contributes a specified percentage of each eligible employee's
        contribution. The Company's contributions totaled approximately $7,000
        and $4,000 in 1997 and 1996, respectively.
    
 (14)   Income (loss) per common share

        As discussed in Note 2, the Company adopted SFAS No. 128 effective
        December 31, 1997. The following table illustrates the computation of
        basic and diluted loss per share under the provisions of SFAS No. 128.

</TABLE>

        The computation of diluted loss per share for 1997 and 1996 excluded the
        effect of incremental common shares attributable to the exercise of

(1) Options to purchase an aggregate of 539,850 shares of Common Stock were

    year ended December 31, 1997. Included were 332,850 options granted to

    cancellation/regrant program.

(2) Options granted have a term of ten years, subject to earlier termination on
    certain events related to termination of employment or service to the
    Company.

(3) The potential realizable value is calculated based on the term of the option
    at its time of grant (10 years). It is calculated by assuming that the stock
    price appreciates at the indicated annual rate compounded annually for the
    entire term of the option and that the option is exercised and sold on the
    last day of its term for the appreciated stock price. No gain to the option
    holder is possible unless the stock price increases over the option term.

(4) Regrant of 10,000 options on March 20, 1997 in connection with the Company's

The Company implemented an option cancellation/regrant program for directors,
executive officers, and all other employees holding stock options with an
exercise price per share in excess of the market value of STM's common stock at
the time the cancellation/regrant occurred. Optionees who accepted the repricing
agreed that the re-granted options would vest ratably over a period one year
longer than the vesting period of the options cancelled. The program was
effected on March 20, 1997 and 332,850 options in excess of $7.125 per share
were cancelled and 332,850 new options were granted with an exercise price of
$7.125.

ITEM 13 - CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        In June 1994, the Registrant sold 693,188 shares of newly issued common
stock at a price of $10.00 per share to Berjaya Cayman, a wholly-owned
subsidiary of Berjaya Group Berhad. In addition, Berjaya Cayman purchased an
additional 528,106 shares of common stock from the open market and from certain
former shareholders of the Company, COM.NET S.p.A. ("COMNET") and IMI Capital
Markets USA Corporation. A major shareholder and the Chairman of the Board of
Directors of Berjaya Group Berhad is also a major shareholder and a director of
Mutiara Telecommunications SDN ("Mutiara") a customer of the Company. The
Company made sales of products and provided services to Mutiara approximating
$5,873,000 in 1995. The Registrant believes that the terms and conditions of
sales to Mutiara were negotiated at arm's length and are no less favorable than
those that could be entered into with independent parties.

        In 1997 and 1996, the Company contracted with Gulf Communications
International, Inc. ("GCI") in the normal course of business to provide
installation services. GCI is 50% owned by an officer of the Company. Total
purchases by the Company from GCI were approximately $720,000 and $469,000 in
1997 and 1996, respectively.

        In March 1998, the Company completed a $10 million equity offering of
shares of STM and Direc-To-Phone International, Inc. ("DTPI"), the Company's
subsidiary, to Pequot Private Equity Fund L.P. ("Pequot"), the private
investment vehicle of Dawson-Samberg Capital Management, Inc. Through the
transaction, Pequot acquired 571,429 shares in the Company. Dawson-Samberg
Capital

Management, Inc. is the beneficial owner of these shares. In addition, they
purchased 182,500 shares in the open market which approximates to 10% of the
outstanding shares of common stock of the Company. Coinciding with the equity
offering, two officers of Pequot were appointed to DTPI's Board of Directors.
