     All of the 2,500,000 shares of Common Stock offered hereby (the "Offering")
are being sold by Innova Corporation ("Innova" or the "Company"). The Company
designs, manufactures and supports millimeter wave radios for use as
short-to-medium-distance wireless communications links in telecommunications

Stock of the Company. It is currently estimated that the initial public offering
price will be between $10.00 and $12.00 per share. See "Underwriting" for a
discussion of factors considered in determining the initial public offering
price. Following the Offering, the Company's directors and officers and their
affiliates will beneficially own approximately 65% of the Company's outstanding
Common Stock (assuming the exercise of all warrants and vested and unvested
options held by them) and will therefore have the ability to elect the Board of
Directors and control the management of the Company and its affairs and
business. The Common Stock has been approved for quotation on the Nasdaq
National Market under the symbol "INVA", subject to official notice of issue.
    
 
     THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK. SEE "RISK
FACTORS" BEGINNING ON PAGE 5.

                                  THE COMPANY
 
   
     Innova designs, manufactures and supports millimeter wave radios for use as
short- to medium-distance wireless communication links in developed and
developing telecommunications markets. Innova's products enable
telecommunications service providers to establish reliable and cost-effective
voice, data and video communications links within their networks. Innova's
products operate in frequencies ranging from 13-38 GHz and may be used in
various applications, including cellular and PCS/PCN networks, broadband
communications, local loop services and long distance networks.
    
 
   
     In recent years, growing demand for telecommunications services has been
driven by the emergence of improved technologies and by the recognition that
effective communications can enhance business productivity and accelerate
economic growth. Regulatory changes, including the privatization of state-run
telephone monopolies, allocation of additional radio spectrum and licensing of
new entrants to the telecommunications market, have created a competitive
environment in which a growing number of service providers are seeking to meet
this demand and capture market share by rapidly establishing new networks and
expanding existing networks.
    
 
     Millimeter wave radios have become an increasingly critical component of
telecommunications networks. As a result, telecommunications service providers
have focused on the quality and lifetime ownership cost of these systems. Innova
has combined its expertise in radio frequency ("RF") systems architecture and
software design to create reliable, cost-effective, intelligent and feature-rich
millimeter wave radio systems that are easy to install, maintain and upgrade.
 
   
     Innova's millimeter wave radio systems are designed to operate at multiple
E1/T1 rates in the high frequency bands used for the transmission of voice, data
and video traffic. Innova's products are based on a common system architecture
and are software configurable. Innova's radio systems consist of an Indoor Unit
("IDU"), which interfaces with the user's network and is digitally linked to an
Outdoor Unit ("ODU"), which transmits and receives the RF signal. The common
embedded software platform in the IDU and ODU is simple network management
protocol ("SNMP") compliant and provides the ability to remotely monitor and
manage Innova's radios within a network using the service provider's network
management system.
    
 
   
     Innova's objective is to be a leading provider of digital millimeter wave
radios. Innova's strategy is to: (i) continue to focus on enhancing existing and
developing new solutions for the point-to-point millimeter wave radio market;
(ii) expand the geographic coverage and increase the market penetration of its
products by strengthening existing and establishing new strategic distribution
relationships; (iii) leverage its existing system architecture to be
first-to-market with high-quality, cost-effective radios; and (iv) further
automate its product calibration and test processes to promote quality control
and cost-effective manufacturing and to improve productivity.
    
 
     Innova markets its products principally to systems integrators with a
strong regional presence in Europe, Latin America and Asia. Innova seeks to
develop strategic relationships with these systems integrators, which provide
field engineering, installation, project financing and support to service
providers. To date, Innova has entered into distribution agreements with MAS
Technology Limited ("MAS"), NERA ASA ("NERA") and Societe Anonyme de
Telecommunications ("SAT"). Innova also markets its products directly to service
providers in the U.S. and internationally. To date, the Company has supplied
products, either through distribution relationships or directly, to Alestra
(Mexico), Associated Communications (U.S.), Avantel (Mexico), Bouygues Telecom
(France), Globtel (Slovakia), Northern Telecom Limited ("Nortel") (Canada),
PacBell Mobile Services (U.S.) and Telcel (Venezuela), among others.
 
   
     The Company was incorporated in Delaware in 1989 and merged into a
Washington corporation in 1991. The Company's headquarters and principal place
of business are located at Gateway North, Building 2, 3325 South 116th Street,
Seattle, Washington 98168-1974. Its telephone number is (206) 439-9121.

                                  RISK FACTORS
 
   
     An investment in the shares of Common Stock being offered by this
Prospectus involves a high degree of risk. In addition, this Prospectus contains
forward-looking statements that involve risks and uncertainties. Discussions
containing such forward-looking statements may be found in the material set
forth under "Prospectus Summary," "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," and "Business," as
well as in this Prospectus generally. The Company's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of many factors, including those set forth in the following risk factors
and elsewhere in this Prospectus. Accordingly, prospective investors should
consider carefully the following risk factors, in addition to the other
information concerning the Company and its business contained in this
Prospectus, before purchasing the shares of Common Stock offered hereby.
    
 
LIMITED OPERATING HISTORY; HISTORY OF SIGNIFICANT LOSSES
 
   
     The Company was incorporated in 1989 and was in the development stage until
mid-1996, when it began shipment of XP4 products, its first line of millimeter
wave radios to be shipped in commercial quantities. From inception through June
30, 1997, the Company generated a cumulative net loss of approximately $43.4
million. From April 1, 1996 through June 30, 1997, the Company generated total
revenues of approximately $14.7 million, of which $14.2 million, or 97%, was
generated in the nine months ended June 30, 1997. For the quarter ended December
31, 1996, the quarter ended March 31, 1997, and the quarter ended June 30, 1997,
the Company's net losses were $2.5 million, $2.1 million, and $900,000,
respectively. Due to the Company's limited operating history, among other
things, there can be no assurance that revenues will not decline. The Company
intends to continue to invest significant amounts in its operations,
particularly to support existing and new product development, increased
manufacturing capacity, and sales and marketing of its recently introduced
product line. Thus, the Company may continue to generate losses even if revenues
increase, and there can be no assurance that the Company will become profitable.
In view of its limited operating history, an investment in the Common Stock must
be considered in light of the problems, expenses, complications and delays
frequently encountered in connection with the development of new products,
markets and operations. As a result of the Company's net losses and limited
operating and sales history, period-to-period comparisons of operating results
may not be meaningful and results of operations from prior periods may not be
indicative of future performance. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
    
 
SIGNIFICANT CUSTOMER CONCENTRATION; DEPENDENCE ON LARGE CONTRACTS
 
   
     The Company is dependent, in significant part, on large contracts with a
limited number of customers. Such contracts are often with systems integrators,
which in turn provide the Company's products to service providers as part of
larger telecommunications infrastructure projects. To date, approximately
eighteen customers have accounted for all of the Company's sales. During the 12
months ended June 30, 1997, three customers, Associated Communications, Nortel
and SAT, accounted for approximately 13%, 44%, and 29%, respectively, or an
aggregate of approximately 86%, of the Company's sales of XP4 products and six
customers accounted for over 93% of XP4 sales. Similarly, as of June 30, 1997,
two customers, Nortel and SAT, accounted for approximately 27% and 40%,
respectively, or an aggregate of approximately 67%, of the Company's backlog.
See "Business -- Backlog." Historically, a significant percentage of the
Company's products have been purchased by customers for use in single
large-scale projects. For example, virtually all of the Company's sales to
Nortel (or approximately 44% of the Company's total XP4 sales through June 30,
1997) were for use in a single large-scale project undertaken by Globtel in
Slovakia. Due to the Company's limited operating history and limited number of
customers to date, it is difficult, if not impossible, for the Company to
accurately predict the mix or nature of infrastructure projects which could be
the basis for its product sales to systems integrators. However, the Company
anticipates that revenue derived from current and future large customers and
large-scale projects will continue to represent a significant proportion of its
total revenues. Because of the small size of the Company's customer base, the
loss of, or reduced demand for products from any customer for any reason,
including business failure of the customer, abandonment or delay of the
underlying project or changes in government policy or general economic
conditions, for example, could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business -- Customers."
    
 
                                        5
<PAGE>   8
 
DEPENDENCE ON DISTRIBUTION RELATIONSHIPS
 
   
     The Company's product distribution strategy is to rely principally on
developing relationships with wireless systems integrators for international
sales, and to make direct sales to service providers in North and Central
America and certain other countries on a case-by-case basis. To date, the
Company has established strategic relationships with NERA and SAT. See
"Business -- Distribution Relationships." There can be no assurance that the
Company will be able to establish distribution relationships with other systems
integrators or that existing relationships will be successful. Thus, the loss of
one or more major distribution relationships, or any significant reduction of
orders by or the business failure of a distributor, could have a material
adverse effect on the Company's business, financial condition and results of
operations. If the Company is unable to establish additional distribution
relationships, it will be unable to implement its distribution strategy and be
required to seek other distribution channels. There can be no assurance that the
Company will be able to successfully implement such alternative distribution
channels or that the costs of doing so, or the result of any delays in
establishing such channels, will not have a material adverse effect on the
Company's business, financial condition and results of operations. Furthermore,
if the Company is unable to produce and sell its products at margins that permit
it to provide systems integrators with a sufficient financial incentive to
distribute the Company's products without adversely affecting the Company's
profitability, the Company's distribution strategy could adversely affect the
Company's net income.
    
 
   
     There are a number of other risks inherent in the Company's distribution
strategy. Agreements with systems integrators are typically terminable on short
notice and generally do not prohibit the systems integrators from distributing
products competitive with those manufactured by the Company. Thus, there can be
no assurance that such distributors will promote the Company's products
aggressively or achieve greater market penetration for the Company's products
than for competing products, that such relationships will not be terminated
prior to achievement of the Company's marketing objectives, or that the
establishment of multiple relationships will not result in excessive competition
among authorized distributors, resulting in price erosion or interference with
service provider relationships or other distribution arrangements. In addition,
because of its distribution strategy, the Company is dependent upon the
financial viability, reputation and success of its distributors, with the result
that the Company's business, financial condition and results of operations could
be adversely affected by factors unrelated to the Company's performance.
    
 
   
     The Company has granted SAT exclusive distribution rights with respect to
France, Hungary, Poland, Italy, Monaco and Andorra, which in certain instances
could survive for up to five years after termination of the Company's
distribution agreement with SAT and prevent the Company from distributing XP4
products in these countries. To the extent that the Company grants similar
rights to other distributors in the future, it will be solely dependent upon the
success of its chosen distributor for sales into a particular territory. In
certain instances, even the establishment of non-exclusive distribution
relationships may preclude or make it more difficult to establish similar
relationships with other systems integrators who compete directly with the
Company's distributors, or prevent the Company from marketing its products
directly. The Company has also granted SAT and NERA the right to produce the
Company's products, and, in certain instances, the right to use the Company's
technology. See "-- Risks Associated with Grants of Limited Manufacturing
Rights." The Company's distribution agreements with SAT and NERA contain
"most-favored customer" clauses, and the Company anticipates that additional
distribution arrangements which it enters in the future may contain similar
clauses. These contractual limitations on the Company's ability to price its
products may adversely affect the Company's operating margins and volume of
sales and, therefore, its business, financial condition and results of
operations.
    
 
SIGNIFICANT FLUCTUATIONS IN RESULTS OF OPERATIONS
 
   
     The Company may in the future experience significant fluctuations in sales,
gross margins and operating results. In connection with its efforts to ramp-up
production of recently introduced products, the Company expects to continue to
make substantial capital investments in equipment, to recruit and train
additional personnel, and possibly to increase outsourcing of components or
invest in additional manufacturing facilities. The Company anticipates that
these expenditures may be made in advance of, and in anticipation of, increased
sales and, therefore, that its gross margins will be adversely affected from
time-to-time due to short-term inefficiencies associated with addition of
equipment, personnel or facilities, and that costs may increase as a percentage
of revenues from time-to-time on a periodic basis. As a result, the Company's
operating results will vary. Because of the relatively small size of the
    
 
                                        6
<PAGE>   9
 
   
Company's customer base and the large-scale nature of the projects in which the
Company's products are typically used, revenues derived from current and future
large customers and large-scale projects will likely represent a significant
portion of revenue in any given period. Thus, a decrease in demand for products
from any customer for any reason, including the business failure of the customer
or abandonment or delay of a particular project, or change in government policy
or general economic conditions may result in significant periodic fluctuations
in sales. Similarly, revenues derived from large-scale projects are often
difficult to forecast due to a relatively long time frame for implementing such
projects. Delays can be caused by delays in site acquisition by service
providers, late deliveries by other vendors, changes in implementation
priorities, slower than anticipated growth, declining demand for the services
that the Company's products support and delays in obtaining regulatory approvals
for installation of such systems. Delays and reductions in the planned
deployment of systems utilizing the Company's products can also be caused by
declines in the local economy or capital availability, and by import controls.
    
 
   
     The Company's operating results for a particular period may be materially
adversely affected by delay, rescheduling or cancellation of one or more
purchase orders. Moreover, purchase orders are often received and accepted
substantially in advance of shipment, and the failure to reduce costs to the
extent anticipated, or an increase in anticipated costs before shipment, could
materially adversely affect the gross margins for such order, and as a result,
the Company's business, financial condition and results of operations. Many new
service providers do not have the financial resources of existing service
providers. To the extent these new service providers are unable to adequately
finance their operations, they may cancel orders. The Company has at times
failed to fill orders on a timely basis due principally to capacity constraints.
A delay in a shipment near the end of a particular quarter, due to, for example,
an unanticipated shipment rescheduling, a cancellation or deferral by a
customer, competitive or economic factors, unexpected manufacturing or other
difficulties, delays in deliveries of components, subassemblies or services by
suppliers, or the failure to receive an anticipated order, may cause sales in a
particular period to fall significantly below the Company's expectations and may
materially adversely affect the Company's business, financial condition and
results of operations for such period.
    
 
   
     A large portion of the Company's expenses are fixed and difficult to reduce
should revenues not meet the Company's expectations, thus magnifying the
material adverse effect of any revenue shortfall. Furthermore, announcements by
the Company or its competitors of new products and technologies could cause
customers to defer or cancel purchases of the Company's systems, which would
materially adversely affect the Company's business, financial condition and
results of operations. Additional factors that have caused or may cause the
Company's sales, gross margins and results of operations to vary significantly
from period to period include: existing and new product development,
introduction and enhancement, including related costs; the Company's ability to
manufacture and produce sufficient products to meet customer requirements;
limitations on manufacturing capacity; the Company's ability to reduce costs;
gain or loss by the Company of significant customers; changes in pricing by the
Company, its customers or suppliers; inventory obsolescence; market acceptance
and the timing of availability of new products by the Company or its customers;
use of different distribution and sales channels; natural disasters or adverse
weather; fluctuations in foreign currency exchange rates; delays or changes in
regulatory approval of the Company's products; increases in warranty and
customer support expenses; and general economic and political conditions. In
addition, the Company's results of operations have been, and will continue to
be, influenced significantly by competitive factors including the pricing and
availability of, and demand for, competitive products. All of the above factors
could materially adversely affect the Company's business, financial condition
and results of operations. As a result, the Company believes that
period-to-period comparisons are not necessarily meaningful and should not be
relied upon as indications of future performance. Due to all the foregoing
factors, it is likely that in some future quarter the Company's operating
results will be below the expectations of public market analysts and investors.
In such event, the price of the Company's Common Stock may be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
DEPENDENCE ON SINGLE PRODUCT LINE
 
   
     Substantially all of the Company's product sales since mid-1996 have been
derived from sales of its 18 GHz, 23 GHz and 38 GHz XP4 radio systems. The
Company's business strategy includes efforts to reduce its reliance on revenues
from its existing products by developing new products and product enhancements,
including a lower cost product line and a high-capacity system. The Company's
prior generation of radios, the XP3, did not achieve market
    
 
                                        7
<PAGE>   10
 
   
acceptance, and there can be no assurance that the Company will be able to
reduce its reliance on sales of its current XP4 products by developing new
products that achieve market acceptance or enhancing its existing products. As a
result, any factor adversely affecting the sales of such products would have a
material adverse effect on the Company's business, financial condition, and
results of operations. See "Business -- Products."
    
 
UNCERTAINTY OF MARKET ACCEPTANCE
 
   
     The Company's success will depend upon its recently developed XP4 radio
systems achieving broad market acceptance. The Company believes that this
acceptance is dependent upon the XP4's ability to successfully compete on the
basis of performance, reliability, cost, ease of installation, adaptability and
upgradeability. The Company must, among other things, offer additional products
with superior price/performance characteristics, supply its products on a timely
and cost-effective basis in sufficient volume to satisfy prospective customers'
requirements and otherwise overcome any reluctance on the part of systems
integrators or service providers to transition to new products. There can be no
assurance that service providers or systems integrators will design
telecommunications networks to include the Company's products, or will continue
to include the Company's systems in their networks in the future, or that the
Company's products will replace existing products or achieve widespread
acceptance in the wireless telecommunications market.
    
 
   
     From its inception through 1992, the Company manufactured a line of
Television Receive Only antennas, most of which were sold to a single customer
in Europe. This product line was discontinued by the Company in 1992. In 1992,
the Company began developing millimeter wave radios. In 1993, the Company
shipped its first radios, based on its initial architecture, the XP3. Because
the XP3 failed to gain market acceptance and proved difficult to manufacture in
commercial quantities, the Company discontinued its production in 1994. Any
failure of the XP4 radio systems to gain and maintain market acceptance, or of
the Company to improve upon its current market position or to achieve acceptable
gross margins, would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
    
 
LIMITED PRODUCTION CAPACITY; NO ASSURANCE OF SUCCESSFUL EXPANSION OF OPERATIONS
 
   
     During the last three fiscal quarters, demand for the Company's products
exceeded its production capacity. This resulted in some delays in delivery of
products and some lost orders. The Company believes that its present
manufacturing capacity continues to be inadequate to meet anticipated demand on
a timely basis. The Company's business plan is to continue to expand its
manufacturing capacity by purchasing additional equipment, hiring additional
personnel, further developing its proprietary test software to improve
productivity, increasing the efficiency of its production processes, and, in
certain instances, by externally subcontracting additional assembly, calibration
and testing processes. In addition, if the Company is to achieve its objectives,
it will be required to significantly expand its sales, marketing and customer
support capabilities. Due to the Company's limited experience with large scale
operations, there can be no assurance that the Company will be able to develop
internally, or contract with third parties for, additional manufacturing
capacity on acceptable terms, that it will be able to maintain the quality of
its products as production increases, or that it will develop the administrative
and other structures necessary to support expanded operations. If the Company is
unable to increase its production capacity significantly, it will not realize
its business plan.
    
 
     The Company's arrangements with its customers typically require that orders
be shipped not more than 60 days after the order. There can be no assurance that
the Company will be able to increase its production capacity at an acceptable
cost or rapidly enough to fill its orders. The failure to assemble and ship
products on a timely basis could damage relationships with customers and result
in cancellation of orders or lost orders, which would have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Manufacturing" and "-- Distributor Relationships."
 
     The Company currently conducts its manufacturing operations for all of its
products in a single facility in Seattle, Washington. If the Company's
facilities or the facilities of its suppliers were incapable of operating, even
temporarily, or were unable to operate at or near full capacity for any extended
period, the Company's business, financial condition and results of operations
could be materially adversely affected. In connection with the expansion of its
capacity, the Company may seek to develop one or more additional manufacturing
facilities, including, possibly, facilities located
 
                                        8
<PAGE>   11
 
   
outside the Seattle, Washington area. Although there can be no assurance such a
facility will be added, the development of any such facilities would
significantly increase the complexity of the Company's operations.
    
 
NO ASSURANCE OF PRODUCT QUALITY, PERFORMANCE AND RELIABILITY
 
   
     The Company's ability to achieve sales will depend in significant part upon
its ability to obtain and fulfill orders from, maintain good relationships with,
and provide support to existing and new customers, and to manufacture products
on a timely and cost-effective basis to meet stringent customer performance
requirements and shipment and delivery dates. Some early shipments of XP4
products experienced some problems with a power source component produced by a
third party. Because of the Company's short operating history and the short time
that the XP4 products have been in production, there can be no assurance that
problems will not occur with respect to the quality, performance and reliability
of the Company's products. If such problems occur, the Company could experience
increased costs or delays in, cancellations of, or rescheduling of orders or
shipments, any of which may have a material adverse effect on the Company's
business, financial condition and results of operations.
    
 
REQUIREMENT FOR RESPONSES TO RAPID TECHNOLOGICAL CHANGE AND REQUIREMENT FOR
FREQUENT NEW PRODUCT INTRODUCTIONS
 
   
     The wireless communications market is subject to rapid technological
change, frequent new product introductions and enhancements, product
obsolescence, changes in customer requirements and evolving industry standards.
To be competitive, the Company must successfully develop, introduce and sell new
products or product enhancements that respond to changing customer requirements
on a timely and cost-effective basis. Any success of the Company in developing
new and enhanced products will depend on a variety of factors including: timely
and efficient completion of system design; timely and efficient implementation
of assembly, calibration, and test processes; sourcing of components;
development and completion of related software; the reliability, cost and
quality of its products; market acceptance; and development and introduction of
competitive products by competitors. The Company has experienced and may
experience delays from time-to-time in completing development and introduction
of new products. Moreover, there can be no assurance that the Company will be
successful in selecting, developing, manufacturing and marketing new products or
product enhancements. The inability of the Company to introduce in a timely
manner new products or product enhancements that contribute to sales could have
a material adverse effect on the Company's business, financial condition and
results of operations. In addition, changes in manufacturing operations to
incorporate new products and processes could cause disruptions in production,
which, in turn, could adversely affect customer relationships and the market's
acceptance of the Company's products, and have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Manufacturing" and "-- Research and Development."
    
 
MANAGEMENT OF GROWTH
 
   
     The growth of the Company's operations since the introduction of the XP4
product line has imposed, and will continue to impose, a significant strain on
the Company's financial resources as well as its product design, assembly, test
and calibration capabilities. To alleviate the impact of the strain, the Company
must successfully manage the transition to higher manufacturing volumes,
establishment of additional facilities, control of overhead expenses and
inventories, development, introduction, marketing and sales of new products and
product enhancements, management and training of its employees, and monitoring
of third-party contractors and suppliers. Accordingly, the Company will need to
significantly expand its internal management and information systems and
implement necessary procedures and controls. Failure to develop and implement
these systems, procedures and controls to effectively manage the Company's
growth in operations in a timely manner could have a material adverse effect on
the Company's business, financial condition and results of operations.
    
 
     The principal means by which the Company maintains its books and records as
well as the bulk of its purchasing and manufacturing data is a relatively simple
PC-network based system. To the extent that the Company continues to grow, this
system may need to be replaced or upgraded.

NO ASSURANCE OF COST REDUCTIONS
 
     To compete successfully, the Company believes that it needs to achieve
significant reductions in production costs. The Company's objective is to
achieve these reductions through engineering improvements and economies of scale
in production and purchasing. There can be no assurance that the Company will be
able to achieve the desired cost savings. Its failure to do so would have a
material adverse effect on its business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
POSSIBLE DECLINE IN PRICES
 
   
     The Company believes that average selling prices and gross margins for its
products will decline as such products mature, as volume price discounts in
contracts take effect and as competition intensifies, among other factors. To
offset declining selling prices, the Company believes that it must successfully
reduce the costs of production of its existing products and introduce and sell
new products and product enhancements on a timely basis at a lower cost or that
incorporate features that enable them to be sold at higher average selling
prices. To the extent that the Company is unable to reduce costs sufficiently to
offset declining average selling prices, the Company's gross margins will
decline, and such decline would have a material adverse effect on the Company's
business, financial condition, results of operations and particularly on the
Company's ability to profitably pursue its distribution strategy. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Research and Development" and "-- Distribution
Relationships".
    
 
SINGLE OR LIMITED SOURCES OF SUPPLY
 
   
     Certain parts and components used in the Company's products, including the
field programmable gate arrays supplied by Xylinx, monolithic microwave
integrated circuits ("MMICs") and hybrids of certain frequencies supplied by
Hewlett-Packard, saw filters supplied by Sawtek, microprocessors supplied by
Motorola and power supplies supplied by Calex are presently only available from
a single source. Certain other parts and components used in the Company's
products are available from a limited number of sources. The Company's reliance
on these single source or limited source suppliers involves certain risks and
uncertainties, including the possibility of a shortage or discontinuation of
certain key components and reduced control over delivery schedules,
manufacturing capability, quality and cost. Any reduced availability of such
parts or components when required could materially impair the Company's ability
to manufacture and deliver its products on a timely basis and result in the
cancellation of orders which could have a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
the purchase of certain key components involves long lead times and, in the
event of unanticipated increases in demand for the Company's products, the
Company may be unable to obtain such components in sufficient quantities to meet
its customers' requirements. The Company does not have guaranteed supply
arrangements with many of its single or limited source suppliers, does not
maintain an extensive inventory of parts or components and customarily purchases
single or limited source parts and components pursuant to purchase orders.
Business disruptions, production shortfalls or financial difficulties of a
single or limited source supplier could materially and adversely impact the
Company by increasing product costs, or reducing or eliminating or delaying the
availability of such parts or components. In such event, the inability of the
Company to develop alternative sources of supply quickly and on a cost-effective
basis could materially impair the Company's ability to manufacture and deliver
its products on a timely basis and could have a material adverse effect on its
business, financial condition and results of operations. See
"Business -- Manufacturing."
    
 
DEPENDENCE ON KEY PERSONNEL
 
   
     The Company's future operating results depend in significant part upon the
continued contributions of each of its eight key technical and senior management
personnel, including Francois Grenon, the Company's Chief Executive Officer,
each of whom would be difficult to replace, as there is a limited number of
people with the necessary skills and experience to develop and manufacture
millimeter wave radios. The development and manufacture of millimeter wave
radios is extremely complicated, and the knowledge and experience of each of its
key technical and management personnel is critical to the Company's ability to
develop new products and product enhancements. The Company has not entered into
long-term employment or non-competition agreements with any of such personnel,
or any other employees, the Company does not maintain key-man life insurance on
any of its key technical or senior management personnel and its senior
management personnel do not generally have significant equity interests in the
Company. In
    
 
                                       10
<PAGE>   13
 
addition, the Company anticipates that it will need additional management
personnel if it is to be successful in increasing production capacity and the
scale of its operations. There can be no assurance that it will be able to
obtain such personnel on acceptable terms.
 
     The Company's future operating results also depend in significant part upon
its ability to attract and retain qualified engineering, manufacturing, quality
assurance, sales, marketing and customer support personnel. Competition for such
personnel is intense. The Company has experienced difficulties over the past
nine months in recruiting sufficient qualified engineering and manufacturing
personnel in the Seattle area, and there can be no assurance that the Company
will be successful in attracting or retaining such personnel. There may be only
a limited number of persons with the requisite skills to serve in these
positions, and it may be increasingly difficult for the Company to hire such
personnel over time. The loss of any key employee, the failure of any key
employee to perform in his or her current position, the Company's inability to
attract and retain skilled employees as needed or the inability of the officers
and key employees of the Company to expand, train and manage the Company's
employee base could materially adversely affect the Company's business,
financial condition and results of operations. See "Business -- Employees" and
"-- Management."
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
   
     Approximately 84% of the Company's XP4 sales through June 30, 1997 were
made to customers located outside of the United States. For the nine month
fiscal period ended December 31, 1996, 50% of total sales were to a single
customer in Canada, and 50% and 28% of total sales for the six months ended June
30, 1997 were to a single customer in each of Canada and France, respectively.
    
 
   
     The Company anticipates that international sales will continue to account
for at least a majority of its sales for the foreseeable future. The Company's
international sales may be denominated in foreign or United States currencies.
The Company does not currently engage in foreign currency hedging transactions
as all sales to date have been in U.S. dollars. However, if a material amount of
future sales are denominated in foreign currency, a decrease in the value of
foreign currencies relative to the United States dollar could result in losses
from such transactions. In such event, the Company might seek to limit its
exposure to foreign currency transactions by hedging strategies. There can be no
assurance that any such strategy would be successful in avoiding
exchange-related losses. With respect to the Company's international sales that
are United States dollar denominated, such a decrease could make the Company's
systems less price-competitive, or could cause distributors or customers to
renegotiate prices for subsequent purchases, both of which could have a material
adverse effect upon the Company's business, financial condition and results of
operations. Additional risks inherent in the Company's international business
activities include changes in regulatory requirements, tariffs and other trade
barriers, political and economic instability, difficulties in staffing and
managing foreign operations, difficulties in managing distributors, customs
requirements, potentially adverse tax consequences, the burden of complying with
a wide variety of complex foreign laws and treaties, difficulties in obtaining
necessary equipment authorizations and the possibility of difficulty in accounts
receivable collections. Distribution and sales agreements entered into with
foreign customers may be governed by foreign laws which may differ significantly
from U.S. laws. Therefore, the Company may be limited in its ability to enforce
its rights under such agreements and to collect damages, if awarded. There can
be no assurance that any of these factors will not have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
     If service providers in developing markets do not construct wireless
telecommunications systems, or construction of such systems is delayed for a
variety of reasons, demand for the Company's products in those markets will be
also limited or delayed. In relying on direct or indirect sales to service
providers in developing markets, the Company may also face economic, political
and foreign currency fluctuations that are more volatile than those commonly
experienced in the United States and other areas.
 
DEPENDENCE ON GROWTH OF WIRELESS COMMUNICATIONS MARKET
 
     The future operating results of the Company depend to a significant extent
upon the continued growth and increased availability and acceptance of cellular
and PCS/PCN and wireless local loop access telecommunications services
internationally and, to a lesser extent, in the United States. There can be no
assurance that the volume and variety of wireless telecommunications services or
the markets for and acceptance of such services will grow, or that
 
                                       11
<PAGE>   14
 
   
such services will create a demand for the Company's systems. If the millimeter
wave radio market fails to grow, or grows more slowly than anticipated, the
Company's business, financial condition and results of operations would be
materially adversely affected. Certain sectors of the communications market will
require the development and deployment of an extensive and expensive
communications infrastructure. In particular, the establishment of cellular and
PCS/PCN networks in the U.S. and other countries will require very large capital
expenditures. There can be no assurance that communications providers have the
ability, or be willing to, make the necessary investment in such infrastructure,
or that the creation of this infrastructure will occur in a timely manner.
Moreover, purchase of the Company's systems for local loop service is dependent
on the pricing of wireless telecommunications services at rates competitive with
those charged by wireline telephone companies. In the U.S., rates for wireless
access are currently substantially higher than those charged by wireline
companies, and there can be no assurance that rates for wireless access will be
competitive with rates charged by wireline companies in the U.S. or elsewhere.
If wireless access rates are not competitive, demand for wireless access may be
materially adversely affected. If the Company allocates its resources, or relies
heavily on a system provider that allocates it resources, to any market segment
that does not grow as rapidly as projected, it may be unable to reallocate its
resources to other market segments in a timely manner, which may curtail or
eliminate its ability to enter such market segments, and may have a material
adverse effect on the Company's business, financial condition and results of
operations.
    
 
INTENSELY COMPETITIVE INDUSTRY
 
   
     The wireless communications market is intensely competitive. The Company's
millimeter wave radio systems compete with other wireless telecommunications
products and alternative telecommunications transmission services. The principal
competitive factors in this market include product performance and reliability,
ability to meet delivery requirements, price, ease of installation, adaptability
and upgradeability and other product features. The Company experiences intense
competition worldwide from a number of leading telecommunications companies that
offer a variety of competitive products and broader telecommunications product
lines, including Alcatel Network Systems, California Microwave, Inc., Digital
Microwave Corporation, Ericsson Limited, Harris Corporation -- Farinon Division,
Nokia Telecommunications and P-COM, Inc., all of which have substantially
greater installed bases, financial resources and production, marketing,
manufacturing, engineering and other capabilities than the Company. The Company
may also face competition in the future from new market entrants offering
competing technologies. In addition, the Company's current and prospective
customers and distributors have developed, are currently developing or could
develop the capability to manufacture products competitive with those that have
been or may be developed by the Company. Certain distributors have access to the
Company's technology or have been granted the right to use the technology for
purposes of manufacturing under defined circumstances. See "-- Risks of Limited
Manufacturing Rights." The Company's future results of operations may depend in
part upon the extent to which these customers elect to purchase rather than
develop and manufacture their own radio systems. The Company expects that its
competitors will continue to improve the performance and lower the price of
their current products, and to introduce new products or new technologies that
may be comparable or superior to the Company's current products, which could
cause a significant decline in sales or loss of market acceptance of the
Company's products or render the Company's technologies obsolete or
non-competitive. The Company expects to continue to experience significant price
competition that may materially adversely affect its gross margins and its
business, financial condition and results of operations. The Company believes
that to be competitive, it will be required to expend significant resources on,
among other items, new product development, and product enhancement and cost
reduction. As a result there can be no assurance that the Company will be able
to compete successfully. See "Business -- Competition."
    
 
POSSIBLE NEED FOR ADDITIONAL CAPITAL
 
   
     The Company's future capital requirements will depend upon many factors,
including the success or failure of the Company's efforts to expand its
production, sales and marketing efforts, the status of competitive products, and
the requirements of the Company's efforts to develop new products and product
enhancements. The Company believes that current capital resources, together with
anticipated net proceeds from the offering are adequate to fund its operations
for at least twelve months. There can be no assurance, however, that the Company
will not require additional financing to accomplish its planned expansion of
production capacity and related infrastructure. In such event, there can be no
assurance that additional financing will be available to the Company on
acceptable terms, or at all, or that such financing may not result in further
dilution to existing stockholders. The Company may be required
    
 
                                       12
<PAGE>   15
 
   
to obtain funds through its arrangements with partners or others that may
require the Company to relinquish rights to certain of its technologies or
potential products or other assets. If adequate funds are not available, the
Company may be required to delay, scale back or eliminate its expansion of
production, administration, and its research and development programs. Any
inability to obtain needed financing by the Company could have a material
adverse effect on its business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."
    
 
POTENTIAL FLUCTUATIONS IN BACKLOG
 
   
     The Company's current backlog consists of a relatively small number of
large orders for XP4 equipment, principally from SAT for use by Bouygues Telecom
and Nortel for use by Globtel, and is attributable largely to limitations in the
Company's current production capacity. Purchase orders are often received and
accepted substantially in advance of shipment and are generally cancelable prior
to shipment. As a result, backlog may not result in revenues or, as of any
particular date, be a reliable indicator of sales for any future period.
Furthermore, the Company's business strategy is to reduce the period between
receipt and shipment of orders by increasing production capacity. Thus, the
Company does not expect backlog will remain at current levels as a percentage of
sales. Furthermore, due to the many factors affecting decisions by customers to
place orders and the relative impact of a small number of large orders, backlog
may fluctuate significantly. Such fluctuations may adversely affect the price of
the Common Stock. See "Business -- Backlog."
    
 
RISKS ASSOCIATED WITH GRANTS OF LIMITED MANUFACTURING RIGHTS
 
   
     Some of the Company's existing and anticipated distribution relationships
with systems integrators involve or may involve the granting of rights enabling
the systems integrators to manufacture millimeter wave radios using the
Company's proprietary designs and technologies. For example, the Company has
granted SAT certain non-exclusive perpetual rights to use XP4 technology to
develop new radios for frequencies below 15GHz, and to manufacture and sell XP4
products in that frequency range, subject to limitations as to the place of
manufacture. The Company has also granted SAT non-exclusive perpetual rights to
manufacture and sell certain XP4 products of 18GHz or greater, subject to
limitations as to the place of manufacture, as well as quantity restrictions
which may be released under certain conditions. As a result of these grants, SAT
may be able to compete directly with the Company in the production and sale of
radios in various frequency ranges. The Company has granted NERA rights to
manufacture XP4 products in the event that the Company fails to meet its
delivery requirements under its distribution agreement with NERA. Distribution
arrangements that the Company enters in the future may contain similar grants of
manufacturing rights. See "Business -- Distribution Relationships." The
negotiation of limited manufacturing rights typically involves highly sensitive
business issues such as sharing of the Company's proprietary information, rights
to Company-developed and jointly-developed improvements, preservation of rights
to next-generation product designs, conditions and limitations under which such
manufacturing rights may be utilized and compensation for the use of proprietary
information and technologies. Because the negotiated compensation to the Company
from third-party-manufactured units results in lower margins than those earned
on Company manufactured units, the Company attempts to negotiate limits on the
amount of third-party manufacturing and to contractually protect its business
interests although it is not always able to do so. There can be no assurance
that negotiated limitations, if any, on the exercise of such rights will be
sufficient to prevent such exercise from having a material adverse effect on the
Company's business, financial condition and results of operations. Nor is there
any assurance that contractual provisions and related legal remedies will be
adequate to prevent distributors from making unauthorized disclosures, or
excessive or unanticipated uses of the Company's proprietary designs and
technologies or sales of such products. Granting of manufacturing rights, in
general may also create competition between the Company and its distributors
over access to critical components that may be in limited or short supply. See
"Business -- Manufacturing".
    
 
EXTENSIVE GOVERNMENT REGULATION
 
   
     Radio communications are subject to extensive regulation by foreign and
U.S. laws and international treaties. The Company's systems must conform to a
variety of international and domestic requirements established to, among other
things, avoid interference among users of radio frequencies and to permit
interconnection of equipment. In order for the Company's radios to be used in a
foreign jurisdiction, regulatory approval for its systems must be obtained and
    
 
                                       13
<PAGE>   16
 
   
end users must comply with such regulations. Regulatory bodies worldwide are
continuing the process of adopting new standards for wireless communication
products. The delays inherent in this governmental approval process may cause
the cancellation, postponement or rescheduling of the installation of
communications systems by the Company's customers, which in turn may have a
material adverse effect on the sale of systems by the Company to such customers.
The Company's arrangements with its distributors generally provide for the
distributor to obtain the regulatory approvals applicable to use of the
Company's products in the countries into which they are sold by the
distributors. The Company believes that its XP4 products currently comply with
all applicable U.S. and foreign regulations in countries in which its sales are
material, but changes in these regulations, the need to comply with regulations
in additional countries in the event of sales into those countries, or a failure
by the Company's distributors to obtain necessary approvals or permits in
connection with sales to service providers in a country could require the
Company to change the features of its radio systems and thereby incur
substantial costs and experience delays in radio system installation or
operation in countries in which its sales are material. Equipment to support new
services can be marketed only if permitted by suitable frequency allocations,
auctions and regulations, and the process of establishing new regulations is
complex and lengthy. To the extent systems integrators or service providers are
delayed in deploying these systems, the Company could experience delays in
orders. These delays could have a material adverse effect on the Company's
business, financial condition and results of operations.
    
 
     The regulatory environment in which the Company operates is subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly impact the Company's
operations by restricting network development efforts by the Company's customers
or end users, making current systems obsolete or increasing the opportunity for
additional competition. Any such regulatory changes could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company might deem it necessary or advisable to modify its
systems to operate in compliance with such regulations. Such modifications could
be extremely expensive and time-consuming. See "Business -- Government
Regulation."
 
UNCERTAINTY REGARDING PROTECTION OF PROPRIETARY RIGHTS
 
   
     The Company does not hold any patents regarding the technology and
expertise involved in the assembly, calibration and testing of its XP4 products.
The Company relies on technological innovations, trade secrets and expertise to
develop and maintain its competitive position, and upon confidentiality
procedures, common law remedies and contractual provisions to protect its
proprietary rights. The Company's agreements with its distributors generally
contain non-competition and non-disclosure provisions prohibiting the
distributor from manufacturing products based on the Company's designs for the
term of the agreement and for a short period thereafter. In general, the Company
has not entered into non-competition agreements with its management and other
employees or into confidentiality and non-disclosure agreements with system
integrators or service providers.
    
 
     The Company's success will depend in part on its ability to protect its
technology and preserve its trade secrets through common law and contractual
restrictions. There can be no assurance that the trade secrecy or other measures
taken by the Company will be adequate to prevent misappropriation of its
technology, or that competitors will not be able to independently develop
technologies having similar or better functions or performance characteristics.
In addition, the laws of some foreign countries do not protect the Company's
proprietary rights to the same extent as do the laws of the United States. There
can be no assurance that the Company will have adequate legal remedy to prevent
or seek redress for future unauthorized misappropriation of the Company's
technology.
 
     The telecommunications industry is characterized by rapid technological
change, with frequent introductions of new products and technologies. As a
result, industry participants often find it necessary to develop products and
features similar to those introduced by others, increasing the risk that their
products and processes may give rise to claims that they infringe the patents of
others. Accordingly, the Company's current and future products and processes, or
uses thereof, may conflict with patents that have been granted or may be granted
to competitors or others. Such competitors or others could bring legal actions
against the Company or its customers, claiming damages and seeking to enjoin
manufacturing, marketing or use of the affected product or processes. Similarly,
the Company may in the future find it necessary to commence litigation in order
to enforce and protect its proprietary rights. If the Company becomes involved
in any such litigation, it could consume a substantial portion of the Company's
resources and result in a significant diversion of management's attention. If
the outcome of any such litigation were adverse to the Company or its customers,
its business, financial condition and results of operations could be materially
adversely
 
                                       14
<PAGE>   17
 
affected. In addition to any potential liability for damages, the Company or its
customers could be enjoined from continuing to manufacture, market or use the
affected product or process, and could be required to obtain a license in order
to continue such manufacture, marketing or use. There can be no assurance that
the Company or its customers would prevail in any such action or that any
license required under any such patent would be made available on acceptable
terms, if at all.
 
   
LIMITATIONS ON USE OF NET OPERATING LOSS CARRYFORWARDS
    
 
   
     Section 382 of the Internal Revenue Code of 1986 (the "Code") imposes
certain limitations on the ability of a "loss corporation" to use its net
operating losses ("NOLs") to offset its future taxable income in taxable years
following an "ownership change" (including an ownership change resulting from
the issuance of stock). In general, an ownership change occurs if the percentage
(as measured by value) of the loss corporation's stock (other than certain
preferred stock) which is owned, directly or indirectly, by one or more 5%
shareholders (or certain groups of shareholders collectively treated as a 5%
shareholder) is increased by more than 50 percentage points over the lowest
percentage of stock owned by such 5% shareholders at any time during the
applicable "testing period" of three years or less. In the event of an ownership
change, the amount of pre-change NOLs that the loss corporation can use to
offset its taxable income in a post-change taxable year will generally be
limited to an amount equal to the product of the "long-term tax-exempt rate" in
effect on the date of the ownership change and the value of the loss
corporation's stock immediately prior to the ownership change (without taking
into account for such valuation purposes certain capital contributions received
by the loss corporation during the two-year period preceding the ownership
change) (the "Section 382 limitation"). The long-term tax-exempt rate is an
interest rate based upon certain specified U.S. Treasury debt obligations
adjusted for differences between rates on taxable and tax-exempt obligations and
announced on a monthly basis by the Internal Revenue Service. In addition, if
the loss corporation does not continue its historic business or continue to use
a substantial portion of its historic assets in its business for a two-year
period following an ownership change, the Section 382 limitation would be
reduced to zero, with the effect that no portion of the pre-change NOLs would be
available to offset future taxable income (except in certain very limited
circumstances).
    
 
   
     The Company has reviewed past issuances of stock, grants of options and
warrants to acquire Company stock and issuances of debt instruments convertible
into Company stock, as well as share transfers among its shareholders, to
determine the effect of such events under Section 382 of the Code. Based on such
review, the Company believes that ownership changes occurred on both February
20, 1992 and February 13, 1995, and that as a result, the NOLs incurred by the
Company prior to such dates are subject to the Section 382 limitation. Thus, to
the extent that the Company's taxable income in a post-change taxable year
exceeds the amount of the Section 382 limitation, the Company's federal income
tax liability for such taxable year would be greater than it would otherwise be
if the pre-change NOLs were fully available to offset such taxable income. The
Company believes that the availability of the cumulative NOL incurred through
February 13, 1995 will not be limited by the Section 382 limitation. The Company
further believes that its issuance of Common Stock pursuant to the Offering,
when combined with other events subsequent to February 13, 1995, should not
result in another ownership change. However, there can be no assurance that
future events, such as the Company's issuance of additional shares of Common
Stock or transfers of outstanding shares of Common Stock by the Company's
shareholders, will not cause an ownership change to occur in the future. In the
event of any such future ownership change, the Company's ability to use some or
all of its NOLs incurred after February 13, 1995 to offset its future taxable
income would also become subject to the Section 382 limitation. As of June 30,
1997 the Company had remaining NOLs of approximately $37.2 million.
    
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price of the Common Stock will be determined
by negotiations between the Company and the Representatives of the Underwriters
and may not be indicative of the market price for the Common Stock in the
future. See "Underwriting" for a discussion of the factors considered in
determining the initial public offering price. There can be no assurance that an
active trading market will develop or be sustained after this Offering. The
Company believes that factors such as announcements of developments related to
the Company's business; announcements of technological innovations or new
products or enhancements by the Company or its competitors; sales by
competitors, including sales to the Company's customers; sales of the Company's
Common Stock into the public market, including by members of
 
                                       15
<PAGE>   18
 
management; developments in the Company's relationships with its customers,
partners, distributors and suppliers; shortfalls or changes in revenues, gross
margins, earnings or losses or other financial results from analysts'
expectations; regulatory developments; fluctuations in results of operations;
and general conditions in the Company's market, or the markets served by the
Company's customers, or the economy could cause the price of the Company's
Common Stock to fluctuate, perhaps substantially. In addition, in recent years
the stock market, in general, and the market for shares of small capitalization
and technology stocks in particular, have experienced extreme price
fluctuations, which have often been unrelated to the operating performance of
affected companies. Many companies in the telecommunications industry have
recently experienced historic highs in the market price of their common stock.
There can be no assurance that the market price of the Company's Common Stock
will not experience significant fluctuations in the future, including
fluctuations that are unrelated to the Company's performance. Such fluctuations
could materially adversely affect the market price of the Company's Common
Stock.
 
   
RISKS ASSOCIATED WITH DEVELOPING TECHNOLOGIES; PRODUCT LIABILITY
    
 
   
     If wireless telecommunications systems are determined, perceived or alleged
to create a health risk, the Company could be named as a defendant, and held
liable, in product liability lawsuits commenced by individuals alleging that the
Company's products harmed them. The occurrence of any of such event could have a
material adverse effect on the Company's business, results of operations and
financial condition. Any alleged health or environmental risk could also lead to
a delay or prohibition against the installation of wireless networks which could
have a material adverse effect on the Company's business, results of operations
and financial condition. In addition, an inability to maintain insurance at an
acceptable cost or to otherwise protect against potential product liability
could inhibit the commercialization of the Company's products and have a
material adverse effect on the Company's business, results of operations and
financial condition. Further, the installation of wireless networks may be
delayed or prohibited by various environmental regulations. Any such delay or
prohibition would have a material adverse effect on the Company's business,
results of operations and financial condition.
    
 
   
BROAD DISCRETION OF MANAGEMENT TO ALLOCATE OFFERING PROCEEDS
    
 
   
     The Company expects to use approximately $5.6 million of the net proceeds
to repay the outstanding principal and interest on its outstanding credit
facility, approximately $8.5 million for the purchase of equipment, and the
remaining $10.0 million for working capital and other general corporate
purposes, such as supporting growth in inventory and receivables, and hiring
additional personnel in connection with the Company's efforts to increase its
production capacity and scope of operations and research and development and
sales and marketing activities. The Company's management will have broad
discretion to allocate the proceeds of the Offering, and the amounts actually
expended for each use listed above may vary significantly depending on a number
of factors, including the amount of future revenues, the amount of cash

product development efforts, technological advances, and the status of
competitive products.
    
 
SHARES ELIGIBLE FOR FUTURE SALE AFTER THE OFFERING
 
   
     Upon completion of this Offering, 12,139,006 shares of Common Stock will be
outstanding, assuming no exercise of outstanding options or warrants to purchase
stock of the Company, (12,514,006 shares if the Underwriters' over-allotment
option is exercised in full) of which the 2,500,000 shares offered hereby
(2,875,000 if the Underwriters over-allotment is exercised in full) will be
freely tradable on the public market, except to the extent that such shares are
held by an affiliate of the Company. Of the remaining 9,639,006 outstanding
shares, 444,629 shares are eligible for public sale immediately after this
Offering pursuant to Rule 144 under the Securities Act of 1933, as amended (the
"Securities Act"), 9,175 shares will become eligible for public sale 90 days
after the date of this Offering pursuant to Rule 701 under the Securities Act
and 7,719,666 shares will become eligible for public sale 180 days after the
date of this Offering upon the expiration of lock-up agreements entered into by
holders of substantially all of the Common Stock not being sold in this Offering
(the "Lock-Up Agreements"). All officers, directors and significant shareholders
and substantially all of the other shareholders of the Company have agreed not
to sell, offer to sell, solicit an offer to buy, contract to sell, grant any
option to purchase, contract to require any other person to purchase, or
otherwise transfer or dispose of any interest in, any shares of capital stock of
the Company, or any securities convertible into or exercisable or exchangeable
for capital stock of the Company, for a period of 180 days after the date of
this Prospectus

without the prior written consent of UBS Securities LLC, with certain limited
exceptions, and the Company has agreed that it will not, until 180 days
following the date of this Prospectus, without the prior written consent of UBS
Securities LLC, sell, offer or agree to sell, contract to sell, grant any option
to purchase, make any short sale or otherwise dispose of any shares of Common
Stock, except that the Company may grant additional options and issue stock
under the 1990 Stock Option Plan and the Director Stock Option Plan or issue
shares of Common Stock upon the exercise of outstanding stock options and
warrants. As of the date of this Prospectus, an additional 1,709,517 shares were
issuable upon exercise of outstanding stock options. Of the 633,458 shares
issuable upon currently exercisable stock options, 456,188 are subject to
Lock-Up Agreements. Upon expiration of the Lock-Up Agreements, such shares will
be eligible for immediate public sale.
    
 
   
     An additional 2,949,137 shares of Common Stock are issuable upon exercise
of warrants outstanding at June 30, 1997, all of which are currently
exercisable. Of these shares, 2,907,233 shares are subject to Lock-Up
Agreements.
    
 
   
     Shareholders who will hold an aggregate of 9,549,177 shares of Common Stock
after this Offering have the right to require the Company to register their
shares for sale under the Securities Act, beginning 180 days after the closing
of this Offering. Sales of substantial numbers of shares of Common Stock in the
public market following this Offering could materially adversely affect the
market price for the Common Stock. See "Shares Eligible for Future Sale" and
"Descriptions of Common Stock -- Registration Rights."
    
 
CONTROL BY EXISTING SHAREHOLDERS; EFFECTS OF CERTAIN ANTI-TAKEOVER PROVISIONS
 
   
     Following the completion of this Offering, members of the Board of
Directors and the officers of the Company, together with entities that may be
deemed affiliates of or related to such persons or entities, will beneficially
own approximately 63% (approximately 65% on a fully diluted basis, assuming the
exercise of all warrants and vested and unvested options held by such persons
and outstanding at June 30, 1997) of the outstanding shares of Common Stock of
the Company. Accordingly, these stockholders are able to significantly influence
the election of the members of the Company's Board of Directors and
significantly influence the outcome of corporate actions requiring stockholder
approval, such as mergers and acquisitions. This level of ownership, together
with certain provisions of the Company's articles of incorporation, equity
incentive plans, bylaws and Washington law, may have a significant effect in
delaying, deferring or preventing a change in control of the Company and may
adversely affect the voting and other rights of other holders of Common Stock.
See "Management -- Directors and Executive Officers," "-- Principal
Stockholders" and "Description of Capital Stock."
    
 
   
IMMEDIATE AND SUBSTANTIAL DILUTION
    
 
   
     Investors in Common Stock in the Offering will experience immediate
dilution in the net tangible book value of their shares. Assuming an initial
public offering price of $11.00 per share, dilution to new investors would be
$8.26 per share. Additional dilution will occur upon exercise of outstanding
stock options and warrants. If all of the shares issuable upon the exercise of
stock options granted pursuant to the Company's stock option plans were issued,
dilution to new investors would be $8.30 per share. If the Company seeks
additional capital in the future, the issuance of shares or convertible debt to
obtain such capital may lead to further dilution. See "Dilution."

                                  THE COMPANY
 
     The Company was incorporated on June 30, 1989 as a Delaware corporation and
reincorporated as a Washington corporation through a merger with a wholly-owned
subsidiary on May 31, 1991. Unless the context otherwise requires, the term
"Company" refers to Innova Corporation and its subsidiaries, Innova Europe
Limited and Techinnova S.A. de C.V. The Company's principal executive offices
are located at Gateway North, Building 2, 3325 South 116th Street, Seattle,
Washington 98168-1974, and its telephone number is (206) 439-9121.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 2,500,000 shares of
Common Stock offered hereby, based on an assumed initial public offering price
of $11.00 per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses payable by the Company, are
estimated to be $24,775,000 ($28,611,250 if the Underwriters' over-allotment
option is exercised in full).
    
 
   
     The Company intends to use a portion of the net proceeds from the Offering
to repay the outstanding principal and accrued interest of its credit line with
Greyrock Business Credit, a Division of NationsCredit Commercial Corporation
("Greyrock Business Credit"). As of June 30, 1997, the outstanding balance of
this credit line, which matures October 31, 1997, was approximately $4.1
million. The Company will also use a portion of the net proceeds of the Offering
to repay the Company's outstanding principal balance and accrued interest on its
term loan with Greyrock Business Credit, which will become due upon consummation
of the Offering. As of June 30, 1997, the outstanding balance on this term loan
was approximately $1.5 million. The credit line and the term loan each bear
interest at the greater of 4.75% above LIBOR or 8% per annum. The Company has
used both the credit line and the term loan for inventory, supplies and
equipment used to manufacture XP4 products and for general working capital
purposes. The Company currently estimates that approximately $8.5 million of the
proceeds will be applied to acquire equipment. The Company expects to use the
balance of the proceeds from the Offering, approximately $10 million, for
working capital and other general corporate purposes, such as supporting growth
in inventory and receivables and hiring additional personnel in connection with
the Company's efforts to increase its production capacity and scope of
operations and research and development and sales and marketing activities.
    
 
     Pending their application, the Company intends to invest the net proceeds
from this Offering in government securities or short-term, interest- or
dividend-bearing investment-grade securities.
 
                                DIVIDEND POLICY
 
     The Company has never paid cash dividends on its Common Stock. The Company
currently intends to retain earnings, if any, to finance the growth and
development of its business and does not anticipate paying any cash dividends or
other distributions on its Common Stock in the foreseeable future.

                                 CAPITALIZATION
 
   
     The following table sets forth the short-term debt and capitalization of
the Company at June 30, 1997 (after giving effect to a 24:1 reverse stock split
and changes in authorized common and redeemable preferred stock, to be effective
upon closing of the Offering) and the short-term debt and capitalization of the
Company as adjusted to give effect to the: (i) conversion of all outstanding
shares of Preferred Stock upon consummation of the Offering; (ii) sale by the
Company of the 2,500,000 shares of Common Stock offered hereby at an assumed
initial public offering price of $11.00 per share, after deducting the
underwriting discounts and commissions and estimated Offering expenses; (iii)
application of the estimated net proceeds of the Offering. See "Use of Proceeds"

                                    DILUTION
 
   
     As of June 30, 1997, the pro forma net tangible book value of the Company's
Common Stock was approximately $8,330,000, or $0.86 per share. Pro forma net
tangible book value per share represents the amount of total tangible assets
less total liabilities, divided by the number of shares of Common Stock
outstanding, after giving effect to pro forma adjustments consisting of the
conversion of the Preferred Stock into Common Stock. Additionally, after giving
effect to the sale by the Company of the shares of Common Stock offered hereby
and after deducting the underwriting discounts and commissions and estimated
offering expenses payable by the Company, the pro forma net tangible book value
of the Company as of June 30, 1997 would have been approximately $33,247,000 or
$2.74 per share. This represents an immediate increase in net tangible book
value of $1.88 per share to existing shareholders and an immediate dilution of
$8.26 per share of Common Stock to new investors purchasing shares of Common
Stock in this Offering. Dilution is determined by subtracting pro forma net
tangible book value per share after the Offering from the amount of cash paid by
a new investor for a share of Common Stock.
    
 
     The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
"Selected Financial Data" and the Company's Consolidated Financial Statements
and Notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
 
   
     Innova designs, manufactures and supports millimeter wave radios for use as
short- to medium-distance wireless communications links in developed and
developing telecommunications markets. The Company began shipping the 23, 26 and
38 GHz models of its XP4 radio systems in the quarter ended September 30, 1996.
As of June 30, 1997 the Company had sold its XP4 radios to a total of 18
customers, generating $12.2 million in total revenues, $6.8 million of which
occurred in the quarter ended June 30, 1997. Through June 30, 1997 approximately
44%, 29% and 13% of the Company's XP4 sales have been to Nortel, SAT and
Associated Communications, respectively. Through June 30, 1997 approximately 84%
of the Company's XP4 sales were made to customers located outside of the United
States. The Company anticipates that international sales will continue to
account for at least a majority of its sales for the foreseeable future. The
Company was a development stage company from its incorporation in 1989 through
March 31, 1996. As of June 30, 1997, the Company had an accumulated deficit of
approximately $43.4 million. After March 31, 1996 the Company changed its fiscal
year-end to December 31.
    
 
   
     The Company's net sales consist primarily of sales of point-to-point
millimeter wave radios to systems integrators, other equipment resellers and
service providers, principally for installation outside the U.S. Other revenues
are generated from the resale of related telecommunications equipment such as
antennas, cables and enclosures. The Company recognizes revenue upon shipment.
    
 
   
     In the period from calendar 1989 to calendar 1992 the Company developed and
manufactured a line of TVRO (Television Receive Only) antennas. Approximately
$3.2 million of these antennas were sold, primarily to a single customer in
Europe, before the product line was discontinued in calendar 1992. The Company
began developing millimeter wave radios early in calendar 1992. The Company
generated its first revenue from the shipment of radios, based on its initial
architecture, the XP3, in late calendar 1993. The Company subsequently
determined that the technology and architecture upon which the XP3 product line
was based was not suitable to meet the evolving needs of the target market. In
late calendar 1994, the Company decided to curtail further development of the
XP3 product line and concentrate its development efforts on a new product
architecture, which it believed would be more reliable and would incorporate
features that would be more attractive to customers. In November 1994, the
Company ceased marketing XP3 products, and for approximately the next year, its
only material revenues consisted of subcontractor fees for manufacturing a
revised model of the XP3 for SAT. During this period, research and development
efforts were devoted to the development of the XP4 product line.
    
 
   
     In calendar 1995, the Company began making significant additions of
experienced management in the engineering, manufacturing, sales and
administrative areas, including a new Chief Executive Officer who took office in
early calendar 1996. From late calendar 1995 to the latter part of calendar
1996, the Company continued to invest in product development and manufacturing
infrastructure, in anticipation of the launch of the XP4 product line, which
occurred in the third quarter of calendar 1996. After an initial evaluation
period, orders for XP4 radios increased late in the final quarter of calendar
1996 and continued to increase in the first two quarters of 1997. Since
launching the XP4 product line, the Company has increased expenditures in an
effort to increase sales and expand manufacturing capacity. In light of the
fundamental changes in the character of the Company's operations during the past
three years, which resulted in the Company changing from a development stage
Company to an operating Company during its most recent fiscal year, the Company
believes that period-to-period comparisons of its financial results should not
be relied upon as an accurate indicator of future performance.
    
 
   
     Since introduction of the XP4 product line, orders have increased more
rapidly than the Company has been able to expand its manufacturing capacity,
resulting in delayed shipping dates and lost orders. The Company's backlog was
approximately $11.6 million as of June 30, 1997. The Company includes in backlog
only customer commitments for which it has received signed purchase orders and
assigned shipment dates within the following 180 days. The Company's
distribution agreements generally provide that products are to be shipped not
more than 60 days after the order and that orders may be cancelled prior to
shipment. The Company believes the current level of backlog, as a
    
 
                                       22
<PAGE>   25
 
   
percentage of sales, is due to inadequate manufacturing capacity and anticipates
that the backlog will decrease as a percentage of sales as manufacturing
capacity increases and delivery times decrease. The Company intends to continue
its efforts to increase manufacturing capacity but expects that sales may
continue to be constrained by capacity limitations through 1997 and into 1998.
    
 
   
     As sales have increased since introduction of the XP4 in the third quarter
of calendar 1996, the Company's gross margins have improved, due to the
Company's ability to absorb fixed and semi-variable operating costs over larger
manufacturing volumes. The Company's gross profits over the past three quarters
have also been favorably affected by lower component costs, particularly
fabricated metal parts and transmit and receive hybrids. These component cost
savings are principally a result of higher volume purchasing, the substitution
of lower cost parts and the redesign of components and circuits. In addition to
component cost savings, the Company is pursuing programs to simplify and reduce
the cost of its assembly, test and manufacturing processes. Realization of
further planned savings is necessary if the Company is to improve gross margins.
There can be no assurance, however, that the Company will be successful in
achieving further cost reductions. The Company also expects that its gross
margins will continue to be affected by a variety of other factors, such as:
increases in lower-margin sales through large distributors; increased investment
in manufacturing facilities or equipment; changes in labor costs resulting from
increasing manufacturing capacity; increased manufacturing or testing
arrangements with distributors; changes in product mix; receipt of royalties
under limited manufacturing licenses; increased sourcing of components and
subassemblies from third-party manufacturers; and potential increased price
competition.
    
 
   
     Continued expansion of the Company's manufacturing capacity will be
required for the Company to achieve its business plan. Such expansion will
require substantial investments in additional capital equipment, the recruiting
and training of additional personnel, and possibly increased sourcing of
components from third-parties or investment in additional manufacturing
facilities. Addition of a new facility and increased manufacturing capacity,
particularly if located in another state or country, is likely to add
significant amounts of fixed overhead to the Company's manufacturing costs and
to appreciably increase the complexity of the Company's operations.
    
 
   
     To the extent sales volumes continue to grow, the accounting and other
systems used by the Company may not be suitable to handle the volume and
complexity of the resulting transactions. At present, the principal means by
which the Company maintains its books and records, as well as the bulk of its
purchasing and manufacturing data, is a relatively simple PC-network based
system. To the extent the Company continues to grow, this system may need to be
replaced or upgraded. The Company is currently in the process of upgrading its
current information management software; however, this upgrade may prove to be
only a first step in dealing with the anticipated needs of the Company.
    
 
   
     The Company has entered into distribution agreements whereby it has agreed
to sell XP4 products at various fixed prices. Certain of these distribution
agreements include "most favored customer" pricing commitments which require the
Company to offer lower prices to such distributors in the event such prices are
offered under like terms and conditions to other customers. In addition, some of
these agreements grant limited manufacturing licenses under certain conditions
or impose penalties for late delivery. The Company anticipates that certain of
its distributors will manufacture a portion of the XP4 radios they sell. To the
extent such manufacturing by the Company's distributors decreases the number of
XP4 units built by the Company, the Company's manufacturing gross profit will be
reduced. As of June 30, 1997, no XP4 products have been manufactured by any of
the Company's distributors.
    
 
   
     The Company's sales may also be affected by a variety of other factors
including the establishment of new distribution relationships, the addition of
direct sales personnel or sales offices, the introduction of new products by the
Company or its competitors, and competitive and other conditions affecting the
telecommunications industry generally. The Company remains dependent on
significant contracts from a limited number of customers. Such contracts are
often with systems integrators, which in turn provide the Company's products to
service providers as part of larger telecommunication system infrastructure
buildouts. Due to the Company's limited operating history and limited number of
customers to date, it is difficult, if not impossible for the Company to
accurately predict the mix or nature of infrastructure projects that provide the
basis for its product sales to systems integrators. The Company anticipates,
however, that revenue derived from current and future large customers and
large-scale projects will continue to represent a significant portion of its
total revenues. Because of the small size of the Company's customer base, the
loss of or reduced demand for products from any customer for any reason,
including business failure of the
    
 
                                       23
<PAGE>   26
 
   
customer, abandonment of the underlying project, or changes in government policy
or general economic conditions, for example, could have a material adverse
effect on the Company's business, financial condition and results of operations.
The Company believes that price competition among manufacturers of millimeter
wave radios is likely to increase over time, which could adversely affect the
Company's sales and margins.
    
 
     In addition to expanding the XP4 product line with additional frequencies
and data rates, the Company is also developing point-to-point millimeter wave
radios with different architectures that are designed to address different
market needs than the XP4. To maintain current or target additional market
opportunities, the Company will need to undertake additional development
programs and to produce new products and product enhancements on a timely and
cost-effective basis. Accordingly, research and development costs are expected
to increase over time.
 
   
     The Company has granted non-qualified stock options to its employees which
in some cases have required attainment of performance goals prior to vesting.
Generally, these options have been granted at exercise prices which the Company
believed to be no less than the fair market value of the underlying Common Stock
as of the date of grant. In 1997, the Company amended previously granted options
to eliminate performance-related vesting criteria. In connection with these
amendments, the Company recorded a non-cash charge to operations of $965,533 for
the six months ended June 30, 1997, which is due primarily to the estimated fair
market value of these amended options exceeding the exercise price on the
amendment date. Additional compensation expense of up to $623,744 will be
recorded over the next 4 years as these options vest.
    
 
   
     The Company accrues for warranty expenses on an estimated basis, based on a
fixed dollar amount for each radio system shipped. Due to the limited operating
history of the Company, this estimate is based in part on experience with the
XP4 and, to a greater extent, on management's experience in the millimeter wave
radio industry generally. Actual warranty expenses for XP4 sales may vary
significantly from the Company's estimates. If warranty expenses exceed the
Company's estimate, or if the Company is required to make in-the-field repairs
or adjustments to a significant number of radio systems, the Company's business,
financial condition and results of operations could be materially adversely
affected.
    
 
   
     The fifth, sixth, seventh, eighth, ninth, tenth and eleventh paragraphs of
this "Overview" section contain forward looking statements. Actual results could
differ materially from those projected in the forward looking statements, as a
result of a number of factors, including those set forth in the section entitled
"Risk Factors." In particular, note the "Risk Factors" entitled "Potential
Significant Fluctuations in Results of Operations," "Significant Customer
Concentration; Dependence on Large Customers," "Intensely Competitive Industry"
and "Limited Production Capacity; No Assurance of Successful Expansion of
Operation."

  SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1996
    
 
   
     TOTAL REVENUES. Net product sales increased to $12.6 million for the six
months ended June 30, 1997, as compared to minimal levels for the six months
ended June 30, 1996. The increase is attributable to sales of XP4 radios, which
were not sold until the quarter ended September 30, 1996. International sales
represented 87% of total net product sales for the six months ended June 30,
1997. Manufacturing contract service revenues, which consisted of fees received
for manufacturing a revised XP3 for SAT, were eliminated due to SAT's decision
to discontinue production of XP3 radios in Innova's facilities for the six
months ended June 30, 1996.
    
 
   
     GROSS PROFIT (LOSS). Gross profit increased to $3.0 million for the six
months ended June 30, 1997, as compared to a loss of $1.9 million for the six
months ended June 30, 1996. The increase in gross profit was attributable to the
sales of XP4 radios, increased manufacturing volumes and reduced unit material
and outside processing costs resulting from higher-volume purchases and lower,
negotiated prices.
    
 
   
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to $3.5 million for the six months ended June
30, 1997 as compared to $1.5 million for the six months ended June 30, 1996. The
increase was due primarily to a $864,000 charge to compensation expense in
connection with amendments to stock options granted in calendar 1996 as well as
increased compensation expense associated with the addition of sales and
marketing staff in the U.S. and U.K. offices to support the launch of the XP4
product line. The Company may incur additional compensation expense in
connection with opening additional sales offices, particularly in certain
international markets and in connection with adding administrative personnel.
The Company anticipates that selling, general and administrative expenses will
continue to increase.
    
 
   
     RESEARCH AND DEVELOPMENT. Research and development expenses decreased to
$2.2 million for the six months ended June 30, 1997 as compared to $2.4 million
for the six months ended June 30, 1996. The decrease in research and development
expenses was primarily due to a $710,000 reduction in consulting expenses, which
was partially offset by an increase in employee compensation costs due to
increased headcount. Research and development expenses incurred for the six
months ended June 30, 1997 were related to refinements and expansion of the XP4
product line and initial planning for the possible development of other
products. The Company believes research and development expenses will increase
in future periods, as the Company continues to increase research and development
headcount.

     OTHER INCOME (EXPENSE). Other expense increased to $337,000 for the six
months ended June 30, 1997 as compared to $131,000 for the six months ended June
30, 1996. The increase was due primarily to increases in interest expense
resulting from additional capitalized leases and borrowings on the Company's
working capital line. The Company anticipates that net interest expense will
decrease due to repayment of debt from the proceeds of the Offering and
investment of the remaining balance.
    
 
   
     INCOME TAXES. No provision for income taxes has been recorded, as the
Company incurred net operating losses through June 30, 1997. As of June 30,
1997, the Company had remaining net operating loss carryforwards of $37.2
million and additional loss carryovers relating to its U.K. subsidiary. The U.S.
net operating loss carryforwards will expire in various amounts from 2005 to
2012. Although the application of these amounts is subject to certain annual
limitations under the Internal Revenue Code of 1986, as amended, the Company
believes that the availability of the cumulative Federal net operating loss
carryforward is not currently limited. However, there can be no assurances that
future events, such as the issuance of additional shares of Common Stock or
transfers of outstanding shares of Common Stock by the Company's shareholders,
will not cause an ownership change to occur in the future and limit availability
of the NOLs. The Company anticipates that its effective income tax rate will
approach the statutory rate after these amounts are applied or expire. The
Company has provided a full valuation allowance on the deferred tax assets
because of the uncertainty regarding realizability. See Note 11 of Notes to
Consolidated Financial Statements.
    
 
  NINE MONTH FISCAL PERIOD ENDED DECEMBER 31, 1996 COMPARED TO THE FISCAL YEARS
ENDED MARCH 31, 1996 AND 1995
 
   
     TOTAL REVENUE. Net product sales increased to $2.1 million for the nine
month fiscal period ended December 31, 1996, as compared to $445,000 and $1.2
million for the fiscal years ended March 31, 1996 and March 31, 1995,
respectively. The increase in net product sales for the nine month fiscal period
ended December 31, 1996 was due to the launch of the XP4 product line in the
quarter ended September 30, 1996. International sales during this nine month
period represented 69% of net product sales. The decrease for the fiscal year
ended March 31, 1996, as compared to the fiscal year ended March 31, 1995, was
due to the decision to discontinue production of XP3 radios. Manufacturing
contract service revenues increased to $1.5 million for the fiscal year ended
March 31, 1996, as compared to $1.2 million for the fiscal year ended March 31,
1995. Manufacturing contract service revenues in each of these periods related
to manufacture of the XP3 radios for SAT, which was substantially discontinued
in the quarter ended March 31, 1996.
    
 
   
     GROSS PROFIT (LOSS). The Company's gross profit increased to a loss of $1.6
million for the nine month fiscal period ended December 31, 1996, as compared to
a loss of $2.0 million and $2.2 million for the fiscal years ended March 31,
1996 and March 31, 1995, respectively. The increase in gross profit for the nine
month fiscal period ended December 31, 1996 was due to increased revenue
resulting from sales of the XP4 products, which more than offset increased
expenses and the decrease in manufacturing contract sales revenue and related
costs resulting from termination of subcontracting services. Losses in the
fiscal years ended March 31, 1996 and March 31, 1995 were the result of the
ramp-up of production capabilities for the XP3 and fixed manufacturing costs
associated therewith. Due to the planned introduction of the XP4, these fixed
costs were not reduced after the decision to end XP3 production.
    
 
   
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased to $2.6 million for the nine month fiscal
period ended December 31, 1996, as compared to $2.3 million and $2.1 million for
the fiscal years ended March 31, 1996 and March 31, 1995, respectively. The
increase for the nine month fiscal period ended December 31, 1996 was due to
increased staffing, both in the U.S. and U.K. offices, associated with launch of
the XP4 product line. Selling, general and administrative expenses for the
fiscal years ended March 31, 1996 and March 31, 1995 reflect continued
investment in marketing and other staff in anticipation of the launch of the XP4
after ending production of XP3 radios. Selling, general and administrative
expenses are anticipated to continue to increase.
    
 
   
     RESEARCH AND DEVELOPMENT. Research and development expenditures were $3.0
million for the nine month fiscal period ended December 31, 1996 as compared to
$4.5 million and $1.9 million for the fiscal years ended March 31, 1996 and
March 31, 1995, respectively. The decrease for the nine month fiscal period
ended December 31, 1996, was due to the shorter period and to the Company's
decision to reduce consulting expenses, which were partially offset by increases
in internal research and development headcount. Research and development
expenses for the nine
    
 
                                       26
<PAGE>   29
 
month fiscal period ended December 31, 1996 were devoted to development of the
XP4 product line, including the development of several frequency and data rate
product variations. The Company anticipates research and development expenses
will increase as the Company focuses on new products in addition to the XP4
product line. The increase in expenses for the fiscal year ended March 31, 1996
as compared to the fiscal year ended March 31, 1995 was attributable to
increased efforts associated with development of the XP4 product line, and
increased expenditures for engineering consulting services.
 
   
     OTHER INCOME (EXPENSE). Other expense for the nine month fiscal period
ended December 31, 1996 decreased as compared to the fiscal year ended March 31,
1996. Other expense decreased due to interest income from investment of proceeds
of equity financing. The increase in interest expense for the fiscal year ended
March 31, 1996 as compared to the fiscal year ended March 31, 1995 was due
primarily to higher average borrowings in anticipation of equity financings. The
Company anticipates that interest expense may increase substantially over time
if sales and, therefore, eligible accounts receivable and working capital line
borrowings, increase and the Company expands its manufacturing capacity. The
Company, however, intends to use the proceeds from the Offering to pay down
working capital borrowings and reduce interest expense.

results could differ materially from those anticipated or projected in the
Forward Looking Statements as a result of a number of factors, including those
set forth in the Section entitled "Risk Factors." In particular, note the Risk
Factors entitled "Significant Fluctuations in Results of Operations,"
"Significant Customer Concentration; Dependence on Large Contracts," "Limited
Production Capacity; No Assurance of Successful Expansion of Operations" and
"Intensely Competitive Industry."
    
 
QUARTERLY RESULTS OF OPERATIONS
 
     The significant fluctuations in the Company's historical quarterly
operating results are principally a function of the fact that the Company was,
until mid-1996, a development stage company. In consequence, these fluctuations
are largely explained by variation in expenses incurred in connection with the
development of the Company's XP4 systems. In addition, the historical quarterly
operating results have been affected by the launch and subsequent
discontinuation of the XP3 radio line, along with the fluctuation in revenues
received by the Company under its agreement with SAT for the subcontract
manufacture for SAT of XP3 products. The discontinuation of XP3 manufacture or
subcontract manufacture did not result in a corresponding decrease in expenses
as the Company maintained staffing levels in anticipation of the launch of the
XP4 product line. The Company may continue to experience significant quarterly
fluctuations in sales, gross margins and operating results; however, these
fluctuations are likely to be caused by different factors than those that
existed in the past, making prediction of the Company's performance difficult,
if not impossible.
 
   
     In connection with its efforts to ramp up production of recently introduced
products, the Company expects to continue to make substantial capital
investments in equipment, recruit and train additional personnel, and may
increase outsourcing of components, or invest in additional manufacturing
facilities. The Company anticipates that these expenditures may be made in
advance of, and in anticipation of, increased sales and, therefore, that its
gross margins will be adversely affected from time to time due to short-term
inefficiencies associated with addition of equipment, personnel or facilities,
and that each cost category will increase as a percentage of revenues from time
to time on a periodic basis. As a result, the Company's operating results will
vary. Because of the relatively small size of the Company's customer base and
large-scale nature of the projects in which the Company's products are typically
used, revenues derived from current and future large customers and large-scale
projects will likely represent a significant portion of revenue in any given
period. Thus, a decrease in demand for products from any customer for any
reason, including the business failure of the customer or abandonment of a
particular project, may result in significant periodic fluctuations in sales.
Similarly, revenues derived from large-scale projects are often difficult to
forecast due to a relatively long time frame for implementing such projects.
Delays can be caused by late deliveries by other vendors, changes in
implementation priorities, slower than anticipated growth and declining demand
for the services that the
    
 
                                       27
<PAGE>   30
 
Company's products support, and delays in obtaining regulatory approvals for
installation of such systems. Delays and reductions in the planned deployment of
systems utilizing the Company's products can also be caused by fluctuations in
the local economy, capital availability, and changes in import controls.
 
   
     The Company has at times failed to fill orders on a timely basis due
principally to capacity constraints. Delay in a shipment near the end of a
particular quarter, for any reason, may cause sales in that quarter to fall
significantly below the Company's expectations and materially adversely affect
the Company's operating results for that quarter.
    
 
   
     Additional factors that may cause the Company's sales, gross margins and
results of operations to vary significantly from period to period include: new
product introductions and enhancements, including related costs; the Company's
ability to manufacture and produce sufficient products to meet customer
requirements; limitations on the Company's manufacturing capacity; the Company's
ability to reduce costs; gain or loss by the Company of significant customers;
reduced demand for the Company's products; existing and new product development
expenses; pricing changes by the Company, its customers or suppliers; inventory
obsolescence; natural disasters or adverse weather; market acceptance and the
timing of availability of new products by the Company or its customers; use of
different distribution and sales channels; fluctuations in foreign currency
exchange rates; delays or changes in regulatory approval of the Company's
products; warranty and customer support expenses; income taxation; and general
economic and political conditions.
    
 
   
     Because of the many factors which may affect the Company's performance in
any particular period and because the Company changed from a development stage
Company to an operating Company during its most recent fiscal year, the Company
believes that period to period comparisons are not necessarily meaningful and
should not be relied upon as indications of future performance.
    
 
   
     The following table sets forth the unaudited results of operations for each
of the six fiscal quarters beginning January 1, 1996 and ending June 30, 1997.
In the opinion of the Company's management, this unaudited financial information
includes all adjustments (consisting only of normal recurring adjustments)
necessary to present fairly the information set forth therein, when read in
conjunction with the Company's audited Consolidated Financial Statements and the
Notes thereto appearing elsewhere in this Prospectus.
    
 
   
     Results of operations for any quarter are not necessarily indicative of the
results that may be expected for any future period. There can be no assurance
that the Company will not experience significant variations in its future
results of operations. See "Risk Factors -- Significant Fluctuations in Results
of Operations."

LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company requires capital principally for capital equipment, investment
in product development activities, operations and more recently for financing
accounts receivable and inventory. To date, the Company has financed its
operations primarily from private placements of equity securities, and, more
recently, bank borrowings. During the nine month fiscal period ended December
31, 1996, and the fiscal years ended March 31, 1996, 1995 and 1994, the Company
raised $9,735,000, $6,790,000, $9,143,000 and $16,274,000, respectively from the
sale of debt and equity securities. Since December 31, 1996, the Company has
raised an additional $8.5 million from the private placement of equity
securities. Investing activities were minimal during these periods.
    
 
   
     The Company has a credit facility with a commercial bank, which provides
for a revolving credit line and a term loan. Outstanding balances on the credit
line bear interest at the greater of the LIBOR rate in effect each month plus
4.875% per annum, or 8% per annum, and matures on October 31, 1997. The term
loan accrues interest at the same rate and is payable upon the consummation of
the Offering. The Company has used both the credit line and the term loan for
inventory, supplies and equipment in the manufacturing of XP4 products, and for
general working capital purposes.
    
 
   
     The Company's cash and cash equivalents increased to $3.8 million at June
30, 1997 as compared to $173,000 at December 31, 1996. Working capital increased
to $4.4 million at June 30, 1997 as compared to a negative ($300,000) at
December 31, 1996. This increase was partly due to receipt of $7.0 million in
proceeds from redeemable preferred stock during the period. Accounts receivable
increased to $5.1 million at June 30, 1997, as compared to $1.7 million at
December 31, 1996. This was the result of increased sales volumes in the six
months ended June 30, 1997. Inventories also increased to $5.9 million at June
30, 1997, as compared to $2.5 million at December 31, 1996. This increase was
related to the increase in manufacturing levels necessary to support increased
sales. The outstanding balance on the working capital line increased to $4.1
million at June 30, 1997 compared to $506,000 at December 31, 1996. Accounts
payable increased to $3.0 million at June 30, 1997 as compared to $1.9 million
at December 31, 1996 largely due to the ramp-up related to the XP4 product.
Investment in equipment and leasehold improvements in the fiscal year ended
March 31, 1996 and the nine-month fiscal period ended December 31, 1996 was $1.0
million in both periods. Investment in equipment and leasehold improvements in
the six months ended June 30, 1997 was $2.8 million.
    
 
   
     Accounts receivable increased to $5.1 million at June 30, 1997, from $1.7
million at December 31, 1996. This increase resulted from the addition of
receivables from sales of the Company's XP4 products. While the Company
anticipates that the proceeds from the Offering together with cash generated
from operations will be sufficient to
    
 
                                       29
<PAGE>   32
 
finance an anticipated increase in inventory and receivables, should receivables
and inventories increase faster than anticipated, the Company could be required
to incur additional indebtedness.
 
   
     The Company intends to use a portion of the proceeds of this Offering to
retire all outstanding borrowings under its credit facilities and to terminate
the revolving credit line and term loan. Under the revolving credit line,
outstanding balances and available borrowing capacity as of June 30, 1997 were
$4.1 million, with $38,000 available to be drawn down. There was $1.5 million
outstanding under the term loan at June 30, 1997, with no additional amount
available to be borrowed.
    
 
   
     As of June 30, 1997 the Company had made $2.8 million of capital
expenditures in 1997, and plans to spend an additional $6.1 million over the
remainder of the fiscal year. The Company anticipates financing these
expenditures with the proceeds of the Offering.
    
 
   
     The Company believes that the net proceeds of this Offering, together with
funds provided by operations, will be sufficient to meet its liquidity
requirements for at least the next 12 months; however, the Company anticipates
securing a new credit facility after the closing of the Offering. To the extent
additional capital is necessary, the Company could be required to obtain
additional credit facilities sell additional equity, debt or convertible
securities. There can be no assurance that additional financing will be
available at the time or in the amounts that may be needed, or that any
financing which is available will be on terms favorable to the Company and its
shareholders.
    
 
   
     While the operating income the Company will rely upon to meet a portion of
its liquidity needs will come in significant part from international customers,
the Company has experienced no appreciable difference in pricing, inventory
levels or receivables realization between its domestic and international
customers. Additionally, as all of the Company's sales to date have been
denominated in U.S. dollars and the Company anticipates that this will continue
for the foreseeable future, the Company's operating revenues are not subject to
appreciable exchange rate risk and the Company has consequently not implemented
any programs to specifically address such risk.

OVERVIEW
 
   
     Innova designs, manufactures and supports millimeter wave radios for use as
short- to medium-distance wireless communication links in developed and
developing telecommunications markets. Innova's products enable
telecommunications service providers to establish reliable and cost-effective
voice, data and video communications links within their networks. Innova's
products operate in frequencies ranging from 13-38 GHz and may be used in
various applications, including cellular and PCS/PCN networks, broadband
communications, local loop services and long distance networks.
    
 
   
     Innova's millimeter wave radio systems are designed to operate at multiple
E1/T1 rates, are based on a common system architecture and are software
configurable. Innova's radio systems consist of an Indoor Unit, which interfaces
with the user's network and is digitally linked to an Outdoor Unit, which
transmits and receives the RF signal. The common embedded software platform in
the IDU and ODU is SNMP-compliant and provides the ability to remotely monitor
and manage Innova's radios within a network using the service provider's network
management system.
    
 
   
     Innova markets its products principally to systems integrators with a
strong regional presence in Europe, Latin America and Asia. Innova seeks to
develop strategic relationships with these systems integrators, which provide
field engineering, installation, project financing and support to service
providers. To date, Innova has entered into distribution agreements with MAS,
NERA and SAT. Innova also markets its products directly to certain service
providers in the U.S. and internationally. To date, the Company has supplied
products, either through distribution relationships or directly, to Alestra
(Mexico), Associated Communications (U.S.), Avantel (Mexico), Bouygues Telecom
(France), Globtel (Slovakia), Nortel (Canada), PacBell Mobile Services (U.S.)
and Telcel (Venezuela), among others.
    
 
INDUSTRY BACKGROUND
 
     In recent years, worldwide demand for telecommunications services has
increased dramatically. In developed countries, much of the demand has been for
mobile services, while in developing countries demand has been principally for
basic voice service. This demand has been driven by the recognition that
effective communications enhance business productivity and can accelerate
economic growth. Demand has also been driven by the emergence of technologies
that allow the development and deployment of cost-effective, reliable
telecommunications systems.
 
   
     Changes in the regulatory environment in many countries, including the
elimination of monopolies for public telecommunications services, privatization
of government-owned telecommunications organizations and allocation and
licensing of radio frequency spectrum by regulatory authorities, have led to an
increase in the number of telecommunications service providers seeking to meet
this demand. In Europe, for example, recent EU directives prohibit each member
country from restricting competitive access to mobile and local service after
January 1, 1998. In the U.S., the Telecommunications Act of 1996 mandated
competitive access to local telephone networks, and spectrum has been allocated
for five wireless carriers per market. Similar trends are occurring in
developing countries, creating significant opportunities for new entrants in the
telecommunications markets.
    
 
   
     Telecommunications service providers are seeking to rapidly capture market
share by establishing new networks and expanding existing networks in response
to the opportunities created by deregulation, technological advances and
increasing consumer demand. As demand for telecommunications services has
increased, mobile and local service providers have committed significant amounts
of capital to the installation of network infrastructure. In developed
countries, new service providers have the option to lease network capacity from
existing service providers, but often choose not to do so since such leasing
arrangements may be with competitors, may be comparatively expensive and would
not allow the service provider to control the network. As a result, many new
service providers are seeking to build their own networks to provide new or
improved service. In addition, existing service providers have continued to
upgrade and expand their networks to respond to customer demand and increased
competition. In developing countries, both new and existing service providers
are investing heavily to build out network infrastructure to respond to the
demand for basic service.
    
 
     Telecommunications links are a critical element of network infrastructure.
Service providers must choose between wireline or wireless equipment for each of
the many telecommunications links that connect various parts of their
 
                                       31
<PAGE>   34
 
networks. Wireless links are frequently used within telecommunications networks
to interconnect cell sites, switching systems, wireline transmission systems and
other fixed facilities. Wireless links generally involve relatively low initial
capital costs, and may be quickly deployed, especially in urban areas, as no
terrestrial rights of way need to be acquired or cables installed. In addition,
new wireless links can be rapidly added to upgrade or expand existing
telecommunications networks and installed links can be quickly relocated to
respond to shifts in demand.
 
   
     Telecommunications infrastructure developers rely increasingly upon
millimeter wave radio systems for short- to medium-distance wireless links. The
narrower antenna-beam width of millimeter wave frequencies allows a higher
density of links in a given geographic area as compared to lower frequencies.
The atmospheric attenuation of millimeter wave frequencies also allows these
frequencies to be re-used after relatively short distances. As a result,
millimeter wave radios are particularly well-suited to provide wireless
transmission over short- to medium-distances, especially in areas of dense
usage.
    
 
   
     The following diagram illustrates one possible application for millimeter
wave radios within a mobile telecommunications network:

<PAGE>   35
 
   
     As millimeter wave radios have become an increasingly critical component of
telecommunications networks, service providers have focused on the quality and
lifetime ownership cost of these systems. Thus, service providers now demand
more reliable millimeter wave radios in order to reduce costly service
interruptions resulting from the failure of critical links within their
telecommunications networks. Due to increased sensitivity to aesthetic concerns,
congestion in urban environments and use of wireless systems in developing
countries, base stations are becoming smaller and are being placed in less
suitable locations. As a result, service providers now seek radio systems which
are smaller and which perform reliably under adverse conditions. In addition,
larger and more complex telecommunications networks require millimeter wave
radios which can be easily integrated with other parts of the network, avoiding
the need for multiple network management systems. Moreover, the need to rapidly
deploy and upgrade networks requires millimeter wave radios which can be easily
installed without sophisticated tools or special skills, and which can be easily
and quickly reconfigured or field upgraded.
    
 
INNOVA SOLUTION
 
   
     Innova's millimeter wave radio systems are reliable, intelligent,
feature-rich and easy to install, maintain and upgrade. The Company's XP4 radio
systems have been selected for deployment by major systems integrators and new
service providers since their introduction in 1996. The Company believes its
products provide the following benefits:
    
 
   
     Reliability. The Company develops and manufactures radio systems capable of
performing reliably under extreme temperatures. The Company believes the low
parts count, low power consumption and high tolerance to temperature extremes of
its XP4 radio systems make them inherently more reliable than competing
products. In addition, the all-digital communications interface between the XP4
radio systems' Indoor Unit and Outdoor Unit provides greater immunity to
electromagnetic and radio-frequency-induced interference.
    
 
   
     Ease of Installation and Maintenance. The lightweight XP4 can be easily
installed by a single technician without a PC, additional software, specialized
tools or test equipment. The comprehensive embedded software program facilitates
accurate installation by alerting the installer to configuration mistakes with
blinking LEDs. The diagnostic features of the embedded software platform
simplify maintenance by permitting field technicians to determine proper
operation of an installed terminal without disconnecting the radio unit from the
antenna. The XP4 software platform allows control of the entire radio link from
either end of the link, or from a single remote location. In addition, the SNMP
interface allows operation of the entire system from a central, common network
management center. XP4 radio systems also feature a high degree of modular
commonality across frequency bands and data rates. This common architecture
reduces spare parts inventory and training costs.
    
 
   
     Adaptability. The Company believes it is the first to provide millimeter
wave radio systems which provide an open network management capability, thereby
facilitating inclusion of the systems into a variety of telecommunications
networks. Innova's compact XP4 radio systems are designed to occupy less space
and are well-suited to operate in various settings where small size and
resistance to temperature extremes are necessary. The high immunity to
interference provided by the digital communications link between the IDU and the
ODU also allows the XP4 to be deployed in less suitable sites currently
prevalent in developing countries and congested urban areas.
    
 
   
     Ease of Reconfiguration and Upgradeability. Common hardware and a common
software platform across all XP4 radio systems facilitate integration into
network management systems and provide remote reconfiguration and upgrade
capabilities. The comprehensive embedded software platform common to all of
Innova's XP4 radio systems allows network operators to download new code into
the radio units without interrupting traffic or upgrading each unit on site. The
ability to easily reconfigure and upgrade the XP4 systems allow service
providers to enhance and expand their networks without having to replace
installed XP4s.

INNOVA STRATEGY
 
     Innova's objective is to be a leading provider of digital millimeter wave
radios. Innova intends to address the needs of major systems integrators using
millimeter wave radios for wireless connectivity solutions in mobile and local
loop networks, including broadband capability. Innova's strategy includes the
following key elements:
 
   
     Continue To Focus on Millimeter Wave Radio Market. The Company intends to
continue to focus its product development efforts on new and existing
point-to-point millimeter wave radios, and to maintain its competitive advantage
by continuing to focus its development efforts on small, lightweight systems
which perform reliably at extreme temperatures and can be produced, installed
and maintained on a cost-effective basis. The Company believes it was the first
to provide millimeter wave radio systems with a SNMP-compliant architecture, and
that it was the first to develop, produce and deliver 24 GHz equipment for use
in the U.S. market in response to allocation of 24 GHz spectrum by the FCC. The
Company intends to further expand the frequency range and traffic capacity of
its systems, and is in the process of developing prototypes of possible products
designed for new applications and upgrades of several of the existing products.
    
 
   
     Expand Distribution Through Strategic Relationships. The Company intends to
expand the geographic coverage and increase the market penetration of its
products by strengthening existing, and establishing new, strategic
relationships with major systems integrators with strong regional presences
throughout the world. The Company believes that the cost-effective architecture
of its products provides a competitive advantage in developing relationships
with major systems integrators. The Company intends to focus on further reducing
the cost of its radio systems to maintain that advantage. The Company also
believes its relationships with major systems integrators will become
increasingly important as service providers more often rely on third parties to
supply and build their network infrastructure. The Company believes the ability
of many major systems integrators to offer financing on larger projects, and
supply complementary products and services necessary to build telecommunications
networks, facilitates sales of the Company's products.
    
 
   
     Leverage System Architecture. The Company intends to leverage its system
architecture to realize efficiencies in its product design, assembly and test
processes. The Company believes these attributes will enable the Company to be
first to market with new, reliable products that are cost-effective and meet the
evolving demands of systems integrators and service providers. The Company plans
to continue to design its system architecture to minimize the number of
components in each system and to maximize the use of common components across
the full range of the Company's products. The Company believes its use of common
modules, components and a common software platform facilitates product
enhancement and new product development by reducing the number of components
that need to be re-engineered.
    
 
   
     Simplify Product Assembly and Test Processes. The Company continually seeks
to refine and simplify its product design and assembly, calibration and test
processes, which are the most significant components of production cost. The
Company believes its rigorous testing processes, including operation of radio
systems at extreme temperatures and use of proprietary software and test
stations, provide a significant competitive advantage. The Company intends to
continue to develop software that increases automation and process reliability
and improves productivity. The Company also believes that increased automation
could allow it to reduce dependence on skilled labor and enable it to establish
additional manufacturing facilities in developing markets to increase market
opportunity.

(1)  The Company expects that the 8E1 and 8T1 configurations will be available
     for volume shipments during the third quarter of 1997.
    
 
     The Company's products are designed to connect to the end user's network
through multiple high-capacity lines. In transmission mode, the Company's Indoor
Unit accepts the customer's traffic from these multiple lines. The
microprocessors in the IDU then combine the multiple signals into a single,
digital signal, which is combined with data used to control functions and
parameters of the radio link, and digitally transmitted over a single coaxial
cable to the Outdoor Unit. The frequency shift key ("FSK")
modulator/demodulator, housed in the ODU, converts the digital signal into the
appropriate radio frequency. The RF signal is then fed into the hybrid
"transmit" module, which increases the signal to the transmitting frequency. The
high-frequency, millimeter wave signal is then passed through a diplexer filter
to the antenna and broadcast to the receiving unit. In receive mode, the signal
is passed from the antenna through the diplexer filter to the hybrid "receive"
module, where the signal is amplified and stepped down to a lower frequency. The
signal is then passed through the demodulator and converted into a digital
signal, before being routed down the coaxial cable to the IDU. In the IDU, the
end user's traffic is separated from the system control data and delivered to
multiple lines for transmission to the end user's network.
 
   
     The diagram below depicts a millimeter wave radio link. Each radio system
consists of an Indoor and an Outdoor Unit which are described more fully in the
following paragraphs.
    
 
                                      LOGO
 
   
     Indoor Unit. The IDU is the interface to the user's network. It is an
assembly mounted indoors, or in a base station, that contains digital signal
processing electronics, including line interface and digital multiplexing
circuitry.
    
 
                                       35
<PAGE>   38
 
   
The IDU also includes the alarm and diagnostic ports, service channel and
SNMP-compliant network management capability. The IDU provides for the ability
to set capacity, frequency and power output of the radio link through software
configuration without requiring access to the outdoor unit.
    
 
     Configuration of the Company's radio systems, including frequency
selection, power output setting, capacity and link ID, along with alarm
monitoring and receive signal level indications, are performed using the
five-button keypad located on the front panel of the IDU, or by using a PC and
the Company's proprietary XPView software interface. In contrast, many competing
millimeter wave systems require mechanical adjustment and manual tuning, which
involve sending maintenance personnel with test equipment to the radio's
installed location. Software embedded in the Company's radio system also
facilitates upgrades of system capacity, with minimal hardware changes.
 
     Outdoor Unit. The ODU consists of a lightweight, compact, integrated RF
electronics enclosure that attaches directly to an antenna. The RF enclosure
contains electronics that, when transmitting, convert, modulate and amplify the
digital signal received from the IDU. Typically, the ODU is installed outdoors
on a tower or rooftop. A simple latch secures the ODU to the antenna, allowing
for vertical or horizontal installation, and permits removal of the ODU without
tools and without affecting antenna alignment.
 
   
     Software. The Company's embedded software platform is common to all XP4
frequency bands and capacity models. It enables control of user configurable
features from the five-button keypad on the IDU. The embedded software code is
also compatible with the Company's custom manufacturing test and calibration
software. This approach facilitates automation of the final test process by
enabling adjustments to equipment parameters through software commands, rather
than the traditional method of manual dip-switches or pots.
    
 
   
     The Company's XPView software provides a remote means of configuring the
Company's radio systems, as well as providing for advanced diagnostics and
maintenance capabilities, including code downloading. The optional SNMP feature
is implemented via a small plug card in the IDU which provides Ethernet, RS232,
and RS422 communication ports for remote link control and remote collection of
status and alarm data.
    
 
   
     The diagram below depicts the internal system architecture of Innova's

SYSTEM ARCHITECTURE
    
 
   
     The Company's system architecture is designed to offer advantages in
reliability, cost, installation and maintenance when compared to competitive
systems. The Company employs a common set of modules and components for all data
rates and frequencies with the exception of the transmit and receive modules and
diplexer filters. This substantially simplifies the logistics of customer
support, purchasing, and manufacturing. The Company incorporates the four-level
FSK modulator/demodulator into the ODU, rather than including it in the IDU. The
Company believes this results in a more reliable design by permitting digital
communications between the IDU and ODU, thereby reducing interference from EMI
or ground loop, by permitting filtering of undesirable noise and eliminating
cable equalization circuitry completely. This also reduces the electronics
contained in the IDU, resulting in a compact indoor unit which occupies only one
rack unit mounting space in telecom cabinets or base stations.
    
 
     The Company's ODU uses advanced miniature, multifunction transmit or
receive hybrid modules which provide for lower power consumption, smaller size
and fewer interconnection cables or assemblies than conventional millimeter wave
radio systems. In addition the Company's proprietary compact diplexer filter
design eliminates the need for bulky separate transmit and receive filters and
an associated circulator. This design approach results in a lighter, more
compact ODU than competing systems.
 
   
     The embedded software platform reduces the number of manufacturing models
by facilitating production of radio systems for use with varying frequency plans
in different countries. In contrast, traditional systems require hardware
variations to adjust to different frequency plans in each country. In addition,
each ODU will support multiple traffic capacities without any hardware changes,
as these modifications are also governed by software. Transmit power level is
also controlled electronically from the IDU. As a result, no field adjustments,
switch settings or other modifications are required to operate an ODU within its
designated tuning range regardless of frequency plan, traffic capacity or
transmitter output power. The intuitive built-in software interface permits
terminal configuration without extensive training or special tests using the
five-button keypad on the face of the IDU. The embedded software platform also
facilitates accurate installation by alerting the installer to mistakes with
blinking LEDs. Software configurability enables the provision of advanced field
diagnostic tools such as RF terminal loopback. In this mode, the transmitter is
tuned to the frequency of the local receiver, enabling operation of the terminal
in RF loopback and verification of proper, error-free performance. In order to
perform similar functions, competing systems require either the use of a bulky,
external turnaround oscillator or the use of complex, internal mechanical
assemblies.
    
 
CUSTOMERS
 
   
     The Company's customers consist principally of systems integrators, which
incorporate XP4 radio systems into a variety of telecommunications networks to
be sold to telecommunications service providers. Systems integrators may also
provide engineering and installation services and project financing for service
providers. These systems integrators develop the network design and provide the
field effort necessary to install, commission and maintain the Company's
systems. Systems integrators are extensively used by fixed and mobile service
providers in Europe, Asia and developing countries. The Company also sells its
products directly to service providers, principally in North America. Service
providers can use the Company's products for various applications, including
cellular and PCS/PCN networks, broadband communications, local loop services,
and access to long distance networks. As of June 30, 1997, 76% of the Company's
sales have been to systems integrators, with the remaining 24% being made
directly to service providers.
    
 
   
     The systems integrators and service providers set forth below have each
placed significant orders for XP4 radios since introduction of the product line
in the quarter ended September 30, 1996. The Company has also received orders
    
 
                                       37

(1) Indicates service providers that purchased equipment from a systems
    integrator.
 
   
     To date, approximately eighteen customers have accounted for all of the
Company's sales of XP4 systems. Sales to Associated Communications, Bachow
Communications and Nortel accounted for approximately 15%, 12% and 44% of the
Company's XP4 sales, respectively, in calendar 1996. For the six months ended
June 30, 1997, Associated Communications, Nortel and SAT accounted for 12%, 44%
and 33%, respectively, of the Company's sales, and as of June 30, 1997, two
customers, Nortel and SAT, accounted for approximately 27% and 40%,
respectively, or an aggregate of 67%, of the Company's backlog scheduled for
shipment in the six months subsequent to June 30, 1997. Paul Bachow, a director
and greater-than-10% beneficial owner of the Company's Common Stock, is the only
shareholder and the President of Bachow Communications. SAT is a greater-than-5%
beneficial owner of the Company's Common Stock. See "Principal Shareholders" and
"Certain Transactions." The Company has entered into agreements with SAT for
exclusive distribution in France, Italy, Poland, Hungary, Andorra and Monaco and
non-exclusive distribution in other countries; with NERA, for distribution
principally in Asia, Latin America and parts of Europe; and with MAS for
distribution principally in New Zealand and Southeast Asia. The Company has also
sold a significant portion of its products to Nortel. The Company anticipates
that its sales will continue to be to a relatively small group of customers,
consisting principally of international systems integrators and, in North
America, service providers. For the nine month fiscal period ended December 31,
1996, 50% of total sales were to a single customer in Canada, and 50% and 28% of
total sales for the six months ended June 30, 1997 were to a single customer in
each of Canada and France, respectively. See Note 13 to Consolidated Financial
Statements.
    
 
   
     The Company's ability to achieve or increase its sales in the future will
depend in significant part upon its ability to obtain and fulfill orders from
existing and new customers and maintain relationships with and provide support
to existing and new customers, its ability to manufacture systems on a timely
and cost-effective basis and to meet stringent customer performance and other
requirements and shipment delivery dates. As a result, any cancellation,
reduction or delay in orders by, or shipments to, any customer, as a result of
manufacturing difficulties or otherwise, may have a material adverse effect upon
the Company's business, financial condition and results of operations. There can
be no assurance that the Company's sales will continue to increase in the future
or that the Company will be able to retain and support existing customers or to
attract new customers.
    
 
DISTRIBUTION RELATIONSHIPS
 
     The Company markets its products principally to systems integrators with a
strong regional presence in countries in Europe, Latin America and Asia. The
Company believes these relationships are a critical component of its ability to
include its systems in major network buildout projects. To date, the Company has
entered into agreements with NERA and SAT as well as other system integrators.
 
   
     NERA Arrangements. NERA ASA has entered into an OEM Purchase and Limited
Licensing Agreement with the Company (the "NERA Agreement") to purchase at least
$5 million of XP4 product kits and components prior to May 30, 1998. The NERA
Agreement authorizes NERA and its affiliated companies to purchase products from
the Company on most-favored-customer pricing and terms and to distribute such
products on a non-exclusive basis in all countries other than France, Hungary,
Poland, Italy, Monaco and Andorra (collectively, the "SAT Territories"), where
    
 
                                       38
<PAGE>   41
 
   
sales by NERA are to be coordinated with SAT on a case-by-case basis. Under the
NERA Agreement, the Company and NERA have committed to cooperative development
of certain new XP4 products and features, and the Company has granted NERA
certain design approval rights, as well as testing rights on XP4 kits purchased
from the Company. The Company has also granted NERA a royalty-free right to
manufacture and test XP4 indoor units solely for sale with the Company's outdoor
units; and a royalty-bearing right to use the Company's designs and technologies
for the purpose of manufacturing XP4 products, effective only upon the
occurrence of one of the following restrictive conditions: (i) the failure of
the Company to timely deliver products for over two months, (ii) the bankruptcy,
termination of business or dissolution of the Company, or (iii) the termination
of manufacturing and promotion by the Company of XP4 products under the NERA
Agreement. The NERA Agreement provides for the Company to pay penalties for late
delivery, to the extent NERA is obligated to make penalty payments to its
customers due to the late delivery. The NERA Agreement has a five-year term
expiring May 30, 2002, at which time all distribution, manufacturing and other
rights will terminate. However, the Company's warranty, maintenance and repair
obligations survive termination. NERA is obligated, during the term of the
agreement and for a two-year period following its termination, not to develop,
manufacture or sell any product based on the Company's products or technologies.
The Company also is considering outsourcing some circuit board assembly to
NERA's Singapore facility.
    
 
   
     SAT Arrangements. The Company has entered into a Cooperation Agreement with
SAT under which it has granted distribution rights to SAT for its XP4 products,
including exclusive rights in the SAT Territories and non-exclusive rights in
all other countries except in North America, Australia and New Zealand. The
Cooperation Agreement prohibits the Company from selling XP4 products directly
or indirectly in any of the SAT Territories. The Cooperation Agreement also
grants distribution rights to the Company with respect to certain SAT products;
assures each of the parties most-favored-customer pricing and terms; specifies
the maximum production capacity required to be allocated to SAT by the Company;
assures SAT access to the Company's supply relationships for custom design parts
and components, on comparable commercial terms; grants SAT the right to
advertise the XP4 products as its own; and provides for cooperation in the
development of certain features of the Company's XP4 product line, and sharing
of technical data on an ongoing basis, subject to confidentiality and other
restrictions on use.
    
 
   
     The Cooperation Agreement also grants SAT a right to immediate use of the
Company's XP4 designs and technologies for the purpose of developing and
manufacturing (i) any product below 15 GHz within the SAT Territories and (ii)
certain products above 15 GHz, subject to limitations as to the place of
manufacture and, in certain cases, to quantity limitations. SAT is also granted
additional rights to use the Company's designs and technologies for the purpose
of manufacturing certain other XP4 products, subject to limitations as to the
place of manufacture but without quantity limitations. These additional rights
are effective only upon the occurrence of certain failures by the Company to
perform certain obligations under the Cooperation Agreement, such as failure of
the Company to timely deliver a minimum percentage of products for over three
months, discontinuation of manufacture of products, wrongful rejection of
purchase orders or failure to afford SAT "most favored customer" terms. In any
such case, the Company's failure must involve at least $100,000 of products. SAT
is required to pay specified royalties to the Company on products manufactured
pursuant to both its conditional and unconditional rights. The Cooperation
Agreement has an initial term of 5 years, expiring October 31, 2001, but is
automatically renewed for successive five-year terms unless terminated by either
party with one year's notice. Upon expiration of the initial term or upon
termination of the Cooperation Agreement due to an uncured material breach by
the Company, all manufacturing rights which are at that time effective will
become irrevocable and fully paid, and SAT will thereafter be entitled to
manufacture certain XP4 products free of any royalties or other compensation to
the Company.
    
 
   
     In conjunction with the Cooperation Agreement, the Company and SAT have
also entered into a Master Purchase Agreement which includes confidential
conditional commitments by SAT to purchase a fixed number of XP4 products in
various frequencies and configurations from the Company within an initial
specified period, and to purchase a specified dollar amount of XP4 products
within a subsequent specified period. The Master Purchase Agreement contains
other provisions regarding product acceptance testing procedures applicable to
SAT's purchase commitment. See "Certain Transactions -- XP4 Product
Arrangements."
    
 
RESEARCH AND DEVELOPMENT
 
   
     The Company has an ongoing research and development program to enhance its
existing products and to introduce new products. The Company invested
approximately $4.5 million and $1.9 million in the fiscal years ended
    
 
                                       39
<PAGE>   42
 
   
March 31, 1996 and 1995, respectively, and $3 million in the nine month fiscal
period ended December 31, 1996 in research and development efforts. Research and
development expense decreased to $2.2 million for the six months ended June 30,
1997 as compared to $2.4 million for the six months ended June 30, 1996. This
decrease was due primarily to savings realized upon transfering research and
development functions from consultants to Company employees. The Company expects
to continue to invest significant resources in product research and development.
    
 
   
     The Company's research and development efforts focus on using existing
product architectures and technology to maintain commonality and minimize
time-to-market for new products and enhancements. The Company's research and
development efforts are currently focused on developing additional models of the
Company's XP4 product line to address higher capacity applications and greater
modulation efficiency, and on leveraging the Company's temperature resistant
technology to develop a low-cost, all-outdoor radio, and the Company has
developed prototypes of these products. The common architecture of the Company's
XP4 products, by limiting the number of new components needed to develop
products or new frequencies, also allows the Company to react quickly to
changing regulatory environments. The Company was the first manufacturer to
develop and ship radios operating in the 24 GHz range in response to the recent
licensing of the 24 GHz spectrum in the U.S. The Company's research and
development efforts continually strive to enhance software features contained in
its products, and to develop products which can be manufactured in a simple and
cost-effective manner.
    
 
   
     The wireless communications market is subject to rapid technological
change, frequent new product introductions and enhancements, product
obsolescence, changes in customer requirements and evolving industry standards.
To be competitive, the Company must successfully develop, introduce and sell new
products or product enhancements that respond to changing customer requirements
on a timely and cost-effective basis. Any success of the Company in developing
new and enhanced products will depend on a variety of factors including: timely
and efficient completion of system design; timely and efficient implementation
of assembly, calibration, and test processes; development and completion of
related software; the reliability, cost and quality of its products; market
acceptance; and development and introduction of competitive products by
competitors. The Company has experienced and may experience delays from time to
time in completing development and introduction of new products. Moreover, there
can be no assurance that the Company will be successful in selecting,
developing, manufacturing and marketing new products or product enhancements.
The inability of the Company to introduce in a timely manner new products or
product enhancements that contribute to sales could have a material adverse
effect on the Company's business, financial condition and results of operations.
    
 
MANUFACTURING
 
   
     The Company performs final assembly and test, quality assurance, packaging
and shipping at its facility in Seattle, Washington. The Company purchases all
of the circuit boards, integrated circuits and other components used in its
products from third-party suppliers. The Company inspects these components for
quality, groups the components into kits by production order and ships the kits
to its subcontractors for initial assembly. As a result of the use of common
components across the full range of XP4 products, the Company's manufacturing
process is flexible and can accommodate significant changes in the frequency or
data rate of radios produced on a daily basis. This flexibility also reduces the
Company's need to maintain a large inventory of finished goods, as radios may be
produced to meet specific customer requirements without the need for significant
lead times, setup costs or changes to the manufacturing process.
    
 
   
     The Company designs its products to provide a high degree of reliability.
The Company inspects and tests its products during the assembly process and
tests finished products using internally developed procedures. The Company
believes its testing procedures at extreme temperatures are among the most
rigorous in the industry. The Company's quality inspection and testing also
include "burn-in" procedures throughout the assembly process to ensure the
quality and reliability of the Company's products. The Company has extensively
invested in computerized test stations reducing dependency on skilled labor and
facilitating a gradual increase in capacity. The Company believes that its
practice of conducting all testing and calibration internally has contributed to
the reliability of its products. To date, the Company's installed base of XP4
radio systems have achieved a field failure rate of less than 2%. The Company
believes that this reliability is the result of its quality assurance
procedures. The Company received ISO 9001 certification in May 1996.
    
 
                                       40
<PAGE>   43
 
   
     Certain parts incorporated in the Company's products are only available
from a single source, including the field programmable gate arrays supplied by
Xylinx, MMICs and hybrids of certain frequencies supplied by Hewlett-Packard,
saw filters supplied by Sawtek, microprocessors supplied by Motorola and power
supplies supplied by Calex and incorporated in the Company's products. Certain
other parts and components used in the Company's products are available from a
limited number of sources. The Company's reliance on these single source or
limited source suppliers involves certain risk and uncertainties, including the
possibility of a shortage or discontinuation of certain key components and
reduced control over delivery schedules, manufacturing capability, quality and
cost. Any reduced availability of such parts or components when required could
materially impair the Company's ability to manufacture and deliver its products
on a timely basis and result in the cancellation of orders which could have a
material adverse effect on the Company's business, financial condition and
results of operations. In addition, the purchase of certain key components
involves long lead times and, in the event of unanticipated increases in demand
for the Company's products, the Company may be unable to obtain such components
in sufficient quantities to meet its customers' requirements. The Company has
established dual sources for transmit and receive hybrids with Hewlett-Packard
Company ("Hewlett-Packard"), among others, through blanket order arrangements
covering estimated requirements for 1997 and 1998. The Company does not have
guaranteed supply arrangements with many of its single or limited source
suppliers, does not maintain an extensive inventory of parts or components and
customarily purchases single or limited source parts and components pursuant to
purchase orders. Business disruptions, production shortfalls or financial
difficulties of a single or limited source supplier could materially and
adversely impact the Company by increasing product costs, or reducing or
eliminating the availability of such parts or components. In such event, the
inability of the Company to establish alternative sources of supply quickly and
on a cost-effective basis could materially impair the Company's ability to
manufacture and deliver its products on a timely basis and could have a material
adverse effect on its business, financial condition and results of operations.
    
 
SALES, MARKETING AND CUSTOMER SUPPORT
 
   
     Innova's sales and marketing efforts are headquartered in the Company's
executive offices in Seattle, Washington. The Company has also established and
staffed small sales, service and customer support facilities in Shirley,
England. In addition, the Company has one sales and customer support
representative in Nashua, New Hampshire and Dallas, Texas. The Company has
recently opened a service and support facility in Mexico City, Mexico. The
Company may increase its overseas presence by opening sales and support offices
in countries not served by its distribution partners. The Company markets its
products directly to service providers in North America and certain other
countries. The Company believes that the contact it achieves with service
providers through such direct sales provides valuable feedback on product
performance and customer needs, which assists the Company in developing new and
enhanced products. The Company promotes its products through participation and
exhibition at trade shows in North America and through promotion of its products
by its system integrators in Europe and Asia.
    
 
   
     The Company believes that the ability of its customer service personnel to
work with systems integrators in resolving any technical problems experienced by
service providers is fundamental to its success. Although system integrators are
responsible for providing customer support to the service providers, the
Company's technical support team must work closely with the systems integrator's
support personnel to promptly and efficiently identify and resolve technical
issues.
    
 
   
     If the Company is selected to submit a proposal or bid by a new customer,
the Company may also be required to conduct system trials or provide units for
customer approval. If system trials or testing are required and successfully
completed, the Company then negotiates a contract with the customer to set
technical and commercial terms of sale. The Company generally targets systems
integrators that are involved in multiple projects including large quantities of
radios. Once a radio system has been tested by a systems integrator, determined
to meet its specification and designed into a service provider's network,
further testing or contract negotiations are generally not required for
successive orders from that systems integrator, substantially shortening the
sales cycle. The process for sales directly to service providers by the Company
is similar to the sales process for the first sale to a systems integrator, in
that it may involve field trials, contract negotiation, and take from three to
six months to complete.

COMPETITION
 
   
     The wireless communications market is intensely competitive. The Company's
millimeter wave radio systems compete with other wireless telecommunications
products and alternative telecommunications transmission media. The principal
competitive factors in this market include product performance and reliability,
ability to meet delivery requirements, price, and product features. The Company
believes that the relatively small size, light weight, low parts count and low
power consumption of its XP4 products, together with the embedded software
platform contained in those products, should allow the Company to compete
favorably with its principal competitors in terms of the reliability,
adaptability, upgradeability and ease of installation of its products. The
Company experiences intense competition worldwide from a number of leading
telecommunications companies that offer a variety of competitive products and
broader telecommunications product lines, including Alcatel Network Systems,
California Microwave, Inc., Digital Microwave Corporation, Ericsson Limited,
Harris Corporation -- Farinon Division, Nokia Telecommunications and P-COM,
Inc., most of which have substantially greater installed bases, financial
resources and production, marketing, manufacturing, engineering and other
capabilities than the Company. The Company may also face competition in the
future from new market entrants offering competing technologies. In addition,
the Company's current and prospective customers, including Nortel, and certain
others which have access to the Company's technology or under some circumstances
are granted the right to use the technology for purposes of manufacturing, could
develop or manufacture products competitive with those that have been or may be
developed by the Company. The Company's future results of operations may depend
in part upon the extent to which the Company's customers elect to purchase from
outside sources rather than develop and manufacture their own radio systems.
There can be no assurance that such customers will rely on or expand their
reliance on the Company as an external source of supply for their radio systems.
    
 
   
     Recently, certain of the Company's competitors have announced the
introduction of competitive products, and the acquisition of other competitors
and competitive technologies. Within the near future, the Company expects its
competitors to continue to improve the performance and lower the price of their
current products, and to introduce new products or new technologies that provide
added functionality and other features that may or may not be comparable to the
Company's products, which could cause a significant decline in sales or loss of
market acceptance of the Company's systems, or render the Company's systems or
technologies obsolete or noncompetitive. The Company expects to continue to
experience significant price competition that may materially adversely affect
its gross margins and its business, financial condition and results of
operations. The Company believes that to be competitive, it will continue to be
required to expend significant resources on, among other items, new product
development, and product enhancement and cost reduction. There can be no
assurance that the Company will be able to compete successfully.
    
 
GOVERNMENT REGULATION
 
   
     Radio communications are subject to extensive regulation by foreign and
U.S. laws and international treaties. The Company's systems must conform to a
variety of international and domestic requirements established to, among other
things, avoid interference among users of radio frequencies and to permit
interconnection of equipment. In order for the Company's radios to be used in a
foreign jurisdiction, regulatory approval for its systems must be obtained and
end users must comply with such regulations. Regulatory bodies worldwide are
continuing the process of adopting new standards for wireless communication
products. The delays inherent in this governmental approval process may cause
the cancellation, postponement or rescheduling of the installation of
communications systems by the Company's customers, which in turn may have a
material adverse effect on the sale of systems by the Company to such customers.
The Company's arrangements with its distributors generally provide for the
distributor to obtain the regulatory approvals applicable to use of the
Company's products in the countries into which they are sold by the
distributors. The Company believes that its XP4 products currently comply with
all applicable U.S. and foreign regulations in countries in which its sales are
material, but changes in these regulations, the need to comply with regulations
in additional countries in the event of sales into those countries, or a failure
by the Company's distributors to obtain necessary approvals or permits in
connection with sales to service providers in a country could require the
Company to change the features of its radio systems and thereby incur
substantial costs and experience delays in radio system installation or
operations by systems integrators or service providers in countries in which its
sales are material. Failure of the Company's radio systems to comply with
current or future regulations could result in delay, suspension or cessation of
radio systems installation or operations by systems integrators or service
providers. Such regulations could
    
 
                                       42
<PAGE>   45
 
   
require the Company to change the features of its radio systems and incur
substantial costs and experience delays to comply with such time-consuming
regulations. Equipment to support new services can be marketed only if permitted
by suitable frequency allocations, auctions and regulations, and the process of
establishing new regulations is complex and lengthy. To the extent systems
integrators or service providers are delayed in deploying these systems, the
Company could experience delays in orders. These delays could have a material
adverse effect on the Company's business, financial condition and results of
operations.
    
 
   
     The regulatory environment in which the Company operates is subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly impact the Company's
operations by restricting network deployment efforts by the Company's customers
or end users, making current systems obsolete or increasing the opportunity for
additional competition. Any such regulatory changes could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company might deem it necessary or advisable to modify its
products to operate in compliance with such regulations. Such modifications
could be extremely expensive and time-consuming.
    
 
   
INTELLECTUAL PROPERTY
    
 
   
     The Company relies on technological innovations, trade secrets and
expertise to develop and maintain its competitive position, and upon
confidentiality procedures, common law remedies and contractual provisions to
protect its proprietary rights. The Company does not hold any patents regarding
the technology and expertise involved in the assembly, calibration and testing
of its XP4 products. The Company has applied for patents on various elements of
its radio systems. There can be no assurance, however, that such pending patent
applications will ultimately issue as patents or, if patents do issue, that the
claims allowed will be sufficiently broad to protect the Company's proprietary
rights or provide any competitive advantage. In addition, there can be no
assurance that issued patents or pending applications will not be challenged or
circumvented by competitors, or that rights granted will provide any competitive
advantage to the Company. The Company's agreements with its distributors
generally contain non-competition and non-disclosure provisions prohibiting the
distributor from manufacturing products based on the Company's designs for the
term of the agreement and for a short period thereafter. In general, the Company
has not entered into non-competition agreements with its management and other
employees or into confidentiality and non-disclosure agreements with system
integrators or service providers. Furthermore, it is likely that the Company's
competitors can obtain samples of the Company's products and, through reverse
engineering, obtain access to proprietary knowledge regarding the Company's
product designs.
    
 
   
     The Company's success will depend in part on its ability to protect its
technology and preserve its trade secrets through common law and contractual
restrictions. There can be no assurance that the trade secrecy or other measures
taken by the Company will be adequate to prevent misappropriation of its
technology, or that competitors will not be able to independently develop
technologies having similar or better functions or performance characteristics.
In addition, the laws of some foreign countries do not protect the Company's
proprietary rights to the same extent as do the laws of the U.S. There can be no
assurance that the Company will have adequate legal remedy to prevent or seek
redress for future unauthorized misappropriation of the Company's technology.
    
 
     The telecommunications industry is characterized by rapid technological
change, with frequent introductions of new products and technologies. As a
result, industry participants often find it necessary to develop products and
features similar to those introduced by others, increasing the risk that their
products and processes may give rise to claims that they infringe the patents of
others. Accordingly, the Company's current and future products and processes, or
uses thereof, may conflict with patents that have been granted or may be granted
to competitors or others. Such competitors or others could bring legal actions
against the Company or its customers, claiming damages and seeking to enjoin
manufacturing, marketing or use of the affected product or processes. Similarly,
the Company may in the future find it necessary to commence litigation in order
to enforce and protect its proprietary rights. If the Company becomes involved
in any such litigation, it could consume a substantial portion of the Company's
resources and result in a significant diversion of management attention. If the
outcome of any such litigation were adverse to the Company or its customers, its
business, financial condition and results of operations could be materially
adversely affected. In addition to any potential liability for damages, the
Company or its customers could be enjoined from continuing to manufacture,
market or use the affected product or process, and could be required to obtain a
license in order to continue such manufacture, marketing or use. There can be no
assurance that the Company or its customers would
 
                                       43
<PAGE>   46
 
prevail in any such action or that any license required under any such patent
would be made available on acceptable terms, if at all.
 
EMPLOYEES
 
   
     As of June 30, 1997, the Company employed 138 full-time and temporary
employees. None of the Company's employees is represented by a collective
bargaining agreement. The Company's future performance will depend in large
measure on its ability to attract and retain highly skilled employees. The
Company has never experienced a work stoppage and believes its relationship with
its employees to be good.
    
 
FACILITIES
 
   
     The Company's corporate offices and research, development and manufacturing
facilities are located in Seattle, Washington, in two leased buildings
aggregating approximately 60,000 square feet. The Company also leases 2,200
square feet of office space in Shirley, England. The Company believes its
facilities are adequate to meet its needs for the next 12 months.
    
 
BACKLOG
 
   
     The Company's backlog was approximately $11.6 million as of June 30, 1997.
The Company includes in backlog only customer commitments for which it has
received signed purchase orders and assigned shipment dates within the following
180 days. The Company's experience has been that customers generally request
shipment within 60 days of their order date. Customer orders have exceeded the
Company's ability to manufacture radio systems. The Company intends to increase
its manufacturing capacity and believes that backlog will decrease, as a
percentage of sales, as the Company becomes able to fill orders on a more timely
basis. Moreover, substantially all of the product orders comprising the
Company's backlog scheduled for shipment in the next six months can be canceled
with limited or no penalties at any time before shipment. Thus, backlog may not
result in revenues or, as of any particular date, be a reliable indicator of
sales for any future period.
    
 
   
LEGAL PROCEEDINGS
    
 
   
     The Company is not currently a party to any material legal proceedings.

DIRECTOR COMPENSATION
 
     All directors of the Company are reimbursed for out-of-pocket expenses
incurred attending meetings of the Board of Directors.
 
   
     The Board of Directors granted Mr. Shattuck, as compensation for his
service as a director during 1996, (i) $1,000 in cash for each regularly
scheduled Board meeting attended and (ii) options to purchase 1,420 shares of
Common Stock, with an exercise price of $1.968 per share and, as compensation
for his service as a director during 1997, $1,000 in cash for each regularly
scheduled Board meeting attended, and options to purchase 1,736 shares of Common
Stock, with an exercise price of $2.88 per share of Common Stock.
    
 
   
     The Company's Director Stock Option Plan (the "Director Plan") was adopted
in June 1997. In connection with the adoption of the Director Plan, each
non-employee director received options to purchase up to 10,000 shares of Common
Stock (other than Mr. Shattuck, whose option was reduced to reflect the option
previously granted for service in 1997, as reflected above) resulting in the
grant of options covering an aggregate of 48,263 shares of Common Stock. These
options vested on the date of grant and had an exercise price of $9.84 per
share, which was determined by the Board of Directors to be not less than the
fair market value of the Common Stock on the date of grant. The Director Plan
provides for additional grants to non-employee directors of options to purchase
4,000 shares of Common Stock commencing on January 1, 1998 and thereafter at
each annual shareholder's meeting, commencing in 1999. The exercise price of
options granted under the Director Plan is determined by a formula based on the
trading price of the Common Stock for the 20 trading days preceding the grant.
One quarter of the options granted vest after one year, with the remainder
vesting in 36 equal monthly increments. Unvested options under the Director Plan
expire upon termination of service other than by death, or disability, to the
extent not exercised. The options are granted automatically without further
action from the Board of Directors, except to the extent necessary to determine
the fair market value of the Common Stock on the date of grant.

    date of grant, with the remaining shares vesting ratably over the next 36
    months. One half of the options were subject to performance vesting criteria
    when granted, but were amended in 1997 to provide for vesting over time.
    
(2) The exercise price of each option was not less than the estimated fair value
    of the Common Stock on the date of grant.
(3) Based upon the estimated fair value of the Common Stock on the date of grant

    assumed annual rates of compounded stock appreciation are mandated by the
    rules of the Securities and Exchange Commission and do not represent the
    Company's estimate or projection of the future price of the Common Stock.
    Actual gains, if any, on stock option exercises are dependent on the future

BENEFIT PLANS
 
   
     Stock Options. The Company's 1990 Stock Option Plan permits options to
purchase up to an aggregate of 2,083,333 shares of Common Stock to be granted to
employees and nonemployees of the Company. The Plan is administered by the Board
of Directors, which has the authority to select individuals who are to receive
options and to specify the terms and conditions of each option so granted,
including the number of shares covered by the option, the type of option
(incentive stock option or nonqualified option), the exercise price (which, in
case of options granted after the effective date of the Offering, must be at
least 100% of the fair market value of the Common Stock), vesting provisions,
and the overall option term. At June 30, 1997, options to purchase an aggregate
of 1,655,298 shares of Common Stock were outstanding under the Plan.
    
 
     401(k) Plan. The Company maintains a 401(k) plan that covers all employees
who satisfy certain eligibility requirements relating to minimum age, length of
service and hours worked. Under the profit sharing portion of the plan, the
Company may make an annual contribution for the benefit of eligible employees in
an amount determined by the Board of Directors, but no such contributions have
been made to date. Under the 401(k) portion of the plan, eligible employees may
make pre-tax elective contributions of up to 10% of their compensation, subject
to maximum limits on contributions prescribed by law.

                              CERTAIN TRANSACTIONS
 
   
FINANCING TRANSACTIONS
    
 
   
     Between 1989 and June 1997, the following officers, directors and
beneficial owners of 5% or more of the Company's capital stock participated in a
complex series of financing transactions pursuant to which the Company issued
seven series of convertible Preferred Stock (Series A, B, C, C1, D, E and F),
warrants to purchase shares of Series A Preferred Stock, warrants to purchase
shares of Common Stock, convertible notes, all of which were subsequently repaid
or converted into one or another series of Preferred Stock, and certain other
notes, all of which have been paid in full: Woodside Fund, Woodside Fund II and
Woodside Fund III (the "Woodside Funds"); UVCC Fund II and UVCC II Parallel
Fund, L.P. (collectively "UVCC"); Tregor Electronique, S.A. ("Tregor"), a
holding company of SAT; Bachow Investment Partners III, L.P. ("Bachow Investment
Partners"), Paul S. Bachow Co-Investment Fund ("Bachow Co-Investment Fund") and
Paul S. Bachow ("Bachow") (collectively, the "Bachow Entities"); Pomona Capital
II, L.P. ("Pomona") and Baupost Limited Partnership 1983 C-1 ("Baupost"); V.
Frank Mendicino ("Medicino") and the V. Frank Mendicino Defined Benefit Pension
Plan (the "Benefit Plan"); Brian Flynn, former acting CEO, and Daniel Nelson,
former Vice President of Manufacturing. Under the Company's Restated Articles of
Incorporation, as amended, each share of Preferred Stock outstanding at the
closing of the Offering will be automatically converted into one share of Common
Stock. Set forth below are descriptions of insider participation in these
transactions over the past three years.
    
 
   
     1994 Series A Financings and Related Bridge Financings. In April 1994, the
Company issued an aggregate of 338,188 shares of Series A Preferred Stock
pursuant to the antidilution rights of certain holders of Series A Preferred
Stock derived from the previous Series A financings, which were completed in
1989, 1990, 1992 and 1993. In this issuance, Woodside Fund and Woodside Fund II
together and UVCC were issued 96,100 and 23,936 shares of Series A Preferred
Stock, respectively. At approximately the same time, Woodside Fund II and
Woodside Fund III and one unaffiliated investor advanced the Company an
aggregate of $246,934 in exchange for non-interest bearing notes (the "1994
Woodside Notes") convertible into Series A Preferred Stock at a price of $7.9168
per share and rights to receive warrants to purchase Common Stock based on the
amount invested, at an exercise price of $0.84 per share. In this transaction,
Woodside Funds received $46,934 of these notes. In May 1994, the rights to
receive warrants to purchase Common Stock were amended to provide the investors
with the right to receive either warrants to purchase Common Stock at an
exercise price of $0.84 per share or warrants to purchase Series A Preferred
Stock at an exercise price of $0.84 per share. These notes were converted in May
1994 as described below. V. Frank Medicinio, the Chairman of the Company's Board
of Directors is a General Partner of the Woodside Funds. Bernard D. Tarr, Jr., a
member of the Company's Board of Directors, is a Managing Director of UVCC.
    
 
   
     In May 1994, $1,700,000 of outstanding convertible non-interest bearing
notes issued in connection with the Series A Financing and the 1994 Woodside
Notes (collectively, the "Series A Notes") were converted into Series A
Preferred Stock at a price of $7.9168 per share, and warrants were issued to
purchase a total of 462,639 shares of Series A Preferred Stock with an exercise
price of $0.84 per share, to 20 investors. In this transaction, Woodside Funds
and UVCC were issued shares of Series A Preferred Stock with an aggregate
purchase price of $757,853 and $131,386, respectively, and warrants to purchase
177,429 and 37,540 shares of Series A Preferred Stock, respectively. In December
1994, the remaining notes issued in connection with the Series A Financing (all
of which were held by unaffiliated investors) were converted into shares of
Series A Preferred Stock with an aggregate purchase price of $500,000 at a price
of $7.9168 per share and warrants to purchase a total of 19,338 shares of Series
A Preferred Stock at an exercise price of $0.84 per share were issued to these
same unaffiliated investors.
    
 
   
     In May 1994, the Company issued Tregor a warrant to purchase 56,378 shares
of Series A Preferred Stock pursuant to the Company's contractual obligation to
adjust SAT's percentage ownership of the Company to 10% in connection with the
conversion of the Series A Notes. The Company no longer has such obligation.
    
 
   
     Each share of Series A Preferred Stock will be automatically converted into
one share of Common Stock (or an aggregate of 1,574,143 shares of Common Stock)
upon consummation of the Offering and all material contractual covenants by the
Company in favor of the Series A Preferred Stock holders will automatically
terminate, other than the registration rights described below. See "Shares
Eligible for Future Sales -- Outstanding Registration Rights."

     Series B Financing. In April 1994, the Bachow Entities acquired a
$1,000,000 convertible note bearing interest at 15% per annum (the "Bachow
Note"). The Bachow Note, including accrued interest of $20,135, was converted
into Series B. Preferred Stock at a price of $6.0850 per share in May 1994 in
connection with the closing of the Series B Financing. In May 1994, the Company
also issued additional shares of Series B Preferred Stock with an aggregate
purchase price of $1,999,997 to the Bachow Entities at a price of $6.0850 per
share along with three options to purchase additional shares of Series B
Preferred Stock. In July and August of 1994, the first of the three options was
fully exercised. Pursuant to the exercise, the Bachow Entities purchased shares
of Series B Preferred Stock with an aggregate purchase price of $2,800,000 at a
price of $6.3679 per share. The second and third options expired unexercised.
    
 
   
     Each of the 804,553 outstanding shares of Series B Preferred Stock will be
automatically converted into one share of Common Stock upon consummation of the
Offering and all material contractual covenants of the Company in favor of the
Series B Preferred Stockholders will automatically terminate upon consummation
of the Offering, other than the registration rights described below. See "Shares
Eligible for Future Sales -- Outstanding Registration Rights."
    
 
   
     1994 Bridge Loan. In September 1994, Woodside Fund III loaned the Company
$178,650 pursuant to a note, which has since been repaid in full. In October
1994, the Bachow Entities loaned the Company an aggregate of $500,000 evidenced
by notes, payable on or before October 31, 1994 and bearing interest at the rate
of 10.75% per annum, with a default interest rate of 15% per annum. These notes
were exchanged for Series C Preferred Stock at a price of $6.3672 per share at
the time of the Series C financing described below.
    
 
   
     SAT Note. In October 1994, SAT loaned the Company $300,000, which was
subsequently repaid in full.

Tregor, UVCC, Woodside Funds, purchased Series C Preferred Stock with an
aggregate purchase price of $997,181, $1,495,771, $159,549 and $944,225,
respectively, Common Stock with an aggregate purchase price of $2,819, $4,229,
$458 and $3,669, respectively, at a purchase price of $.024 per share and
received warrants to purchase 283,859 shares, 425,789 shares, 45,416 shares, and
268,784 shares, of Common Stock, respectively, at a price of $.024 per share in
a financing transaction in which the Company sold Series C Preferred Stock with
an aggregate purchase price of $4,229,792 at a price of $6.3672 per share,
Common Stock with an aggregate purchase price of $11,957 at a price of $.024 per
share, and issued warrants to purchase a total of 1,204,050 shares of Common
Stock at an exercise price of $.024 per share to these persons and 13 other
unaffiliated investors.
    
 
   
     In September and November 1995, the Company sold of Series C1 Preferred
Stock with an aggregate purchase price of $2,890,428 at a price of $6.3672 per
share, Common Stock with an aggregate purchase price of $8,171 at a price of
$.024 per share and issued warrants to purchase a total of 680,917 shares of
Common Stock with an exercise price of $.024 per share to Bachow Investment
Partners, Bachow, UVCC, Woodside Funds, and 14 other unaffiliated investors. In
this transaction, Bachow Investment Partners, Bachow, UVCC and Woodside Funds
acquired Series C1 Preferred Stock with an aggregate purchase price of
$1,520,661, $249,296, and $648,168 respectively, shares of Common Stock with an
aggregate purchase price of $4,229, $705, and $1,832, respectively, and received
warrants to purchase 358,239, 58,728, and 152,695 shares of Common Stock at an
exercise price of $.024 per share, respectively.
    
 
   
     Each of the 1,120,592 outstanding shares of Series C and C1 Preferred Stock
will be automatically converted into one share of Common Stock upon consummation
of the offering and all contractual covenants by the Company in favor of the
holders of Series C and C1 Preferred Stock will automatically terminate, other
than the registration rights described below. See "Shares Eligible for Future
Sales -- Outstanding Registration Rights."
    
 
   
     1995 Bridge Loans. From November 1995 through January 1996 Bachow
Investment Partners, UVCC, Woodside Fund III, and nine other unaffiliated
investors loaned the Company $1,000,000. Of this amount, Bachow Investment
Partners, UVCC and Woodside Fund III advanced $491,921, $87,828, and $291,922,
respectively. The notes (the "1995 Notes") received by the investors were
payable on demand on or after April 1, 1996, and bore interest at a rate of 16%
per annum for 90 days from the date of issuance and at the rate of 21% per annum
thereafter until paid in full. The investors to whom these notes were issued
were also granted rights to receive warrants to purchase Common Stock, the
exercise price of which was to be the lower of $4.80 per share or 80% of the
average price at which the next $20,000,000 of equity is raised by the Company.
The number of warrants to be received was
    
 
                                       51
<PAGE>   54
 
   
determined by multiplying the principle amount of the note by 50% and dividing
the result by the exercise price of the warrants as determined above (the "1995
Bridge Warrants").
    
 
   
     1996 Bridge Loans. In March and April 1996, Bachow Investment Partners,
Bachow, UVCC, Woodside Fund III, and 13 other unaffiliated persons advanced the
Company an aggregate of $6,069,869 as advances in respect of possible purchases
of Series D Preferred Stock. In this transaction, Bachow Investment Partners and
Bachow, UVCC, and Woodside Fund III were issued notes ("Series D Notes") (all of
which were subsequently converted into Series D Preferred Stock) in the
principal amount of $3,543,263, $350,000, and $1,258,078, respectively. In the
event the Company closed a financing at a pre-money valuation greater than $22.5
million, holders of the Series D Notes were eligible to receive warrants to
purchase Common Stock with an exercise price of $.024 upon the consummation of
such financing (the "1996 Bridge Warrants"). The number of shares to be covered
by the 1996 Bridge Warrants was equal to the difference between the number of
shares of Series D Preferred Stock issuable upon conversion of the Series D
Notes, if the notes were converted at a pre-money valuation of $22.5 million,
and the number of shares of Series D Preferred Stock issuable upon conversion of
the Series D Notes if the Series D Financing occurred at a higher valuation.
    
 
   
     Series D Financing. In April 1996, substantially all of the 1995 Notes and
Series D Notes were converted into shares of Series D Preferred Stock with an
aggregate purchase price of $6,000,000, at a price of $3.228 per share with the
balance being paid in cash. Bachow Investment Partners, Bachow, UVCC and
Woodside Fund III received shares of Series D Preferred Stock with an aggregate
purchase price of $4,035,184, $437,828 and $1,550,000 respectively. Upon the
closing of the Series D financing, the Company issued 1995 Bridge warrants to
purchase an aggregate of 193,611 shares of Common Stock at an exercise price per
share of $2.5824. Bachow Investment Partners, UVCC, and Woodside Fund III
received 1995 Bridge warrants to purchase 95,244, 17,004, and 56,521 shares of
Common Stock, respectively. The Company also issued 1996 Bridge Warrants to
purchase an aggregate of 367,082 shares of Common Stock, with Bachow Investment
Partners, Bachow, UVCC and Woodside Fund III receiving 1996 Bridge Warrants to
purchase 211,610, 22,960 and 81,284 shares of Common Stock, respectively.
    
 
   
     In the Series D Financing the Company also issued to Pomona and Baupost
Series D Preferred Stock with an aggregate purchase price of $5,000,000 at a
price of $3.228 per share.
    
 
   
     Each of the 3,717,643 shares of Series D Preferred Stock will be
automatically converted into one share of Common Stock upon consummation of the
offering, and all contractual covenants by the Company in favor of the holders
of Series D Preferred Stock will automatically terminate, other than the
registration rights described below. See "Shares Eligible for Future
Sales -- Outstanding Registration Rights."
    
 
   
     November 1996 Through March 1997 Bridge Financing. In November 1996 and
December 1996, Bachow Investment Partners, Baupost and Pomona, Brian Flynn, UVCC
and Woodside Fund III loaned the Company $572,513, $326,535, $6,507, $71,114 and
$282,450 respectively, or an aggregate of $1,500,000, and received notes in
exchange (the "Series E Notes"). The notes bore interest at 12% per year and
were payable on demand 90 days after issuance. The Series E Notes were
convertible into Series E Preferred Stock at the option of the holder 90 days
from the date of issuance if not repaid by the Company prior to 91 days from the
date of issuance, at a conversion price of $.1345 per share. In a second related
bridge financing in March 1997, Bachow Investment Partners and Bachow advanced
$1,541,395, Baupost and Pomona advanced $371,303, UVCC advanced $172,902 and
Woodside Fund III advanced $686,739, or an aggregate of $3,000,000, for
additional Series E Notes. $1,500,000 of the proceeds from this financing
retired the notes issued in November and December and notes in the remaining
$1,500,000 were converted into Series E Preferred Stock in connection with the
Series E financing described below.
    
 
   
     Series E Financing. In March 1997 Bachow Investment Partners and Bachow,

MANUFACTURING AND DISTRIBUTION ARRANGEMENTS; SALES OF XP3 AND XP4 PRODUCT
    
 
   
     SAT. The Company has entered into several agreements with SAT concerning
technical cooperation in the development of the Company's products, and the
purchase, distribution and manufacture of such products by SAT, as follows:
    
 
     XP3 Product Arrangements. In October 1992, the Company entered into a
Master Agreement which provided for cooperative development of certain products
based on the Company's XP3 architecture, payment by SAT of $800,000 to the
Company upon achievement of certain development milestones, and the granting to
SAT of certain marketing and manufacturing rights as to XP3 products. In June
1993, the Company and SAT entered into an OEM Distributor Agreement pertaining
to the XP3 product line (as modified by four subsequent amendments, the "XP3 OEM
Agreement"), which granted SAT a right to purchase XP3 products on most-favored
customer terms, and a right to distribute such products on an exclusive basis in
France and certain other European countries and on a non-exclusive basis
elsewhere; imposed certain limits on the Company's sales of XP3 products;
granted SAT a right to manufacture XP3 products in France subject to certain
conditions, limitations and royalty obligations; provided for cooperation in
product development and access to component suppliers; and granted SAT a right
of first refusal as to XP4 distribution and manufacturing rights in France and
certain other countries. In December 1994, following a decision by the Company
to concentrate development efforts on its new XP4 product architecture, the
Company and SAT executed a Processor For Hire Agreement (as modified by
subsequent amendments, the "Processing Agreement"), under which SAT acquired the
Company's inventory of XP3 parts and work in process for approximately $2.6
million (paid for in part by satisfying approximately $1.9 million of advances
made to the Company by SAT), and the Company agreed to continue manufacturing
XP3 products for SAT in return for a processing fee based on the Company's
actual costs of manufacturing.
 
   
     The Company's sales of XP3 products to SAT constituted substantially all of
the Company's net product sales of $1,151,605 and $445,229 in the years ended
March 31, 1995 and 1996, respectively, and were $3,000 and $0 in the nine month
fiscal period ended December 31, 1996 and the six months ended June 30, 1997,
respectively. Processing fees received by the Company from SAT under the
Processing Agreement amounted to $1,206,894, $1,516,870, $53,257, and $0 in the
years ended March 31, 1995 and 1996, the nine month fiscal period ended December
31, 1996, and the six months ended June 30, 1997, respectively. The Processing
Agreement was terminated by mutual agreement of the parties in April 1997. On
June 20, 1997, the Company and SAT agreed to terminate the Master Agreement and
XP3 OEM Agreement, and SAT was granted a fully-paid, perpetual, worldwide
license to manufacture, modify and otherwise exploit the XP3 technology. Having
transitioned its product development, sales and marketing, and strategic focus
to the XP4 product line, the Company does not believe that SAT's continuing
rights as to XP3 products pose either a competitive threat or a significant
impediment to the Company's ability to distribute its XP4 products through SAT.

     XP4 Product Arrangements. In November 1995, the Company and SAT entered
into a Memorandum of Understanding providing for joint development of a product
specification for the Company's XP4 product line, joint ownership of an XP4
interface specification subject to certain transfer limitations, efforts by both
parties to develop compatible and complementary product lines, and development
of a plan for purchases of products by each party from the other. This
Memorandum of Understanding was terminated in June 1997. On October 31, 1996,
the Company and SAT entered into a more detailed Cooperation Agreement, which
provides for cooperative development of XP4 products, and grants SAT certain
exclusive and nonexclusive distribution rights as to XP4 products, as well as
certain unconditional and conditional limited rights to manufacture certain XP4
products. See "Risk Factors -- Risks Associated with Grants of Limited
Manufacturing Rights" and "Business -- Distribution Relationships -- SAT
Arrangements." Simultaneously with the Cooperation Agreement, the Company and
SAT entered into a Master Purchase Agreement, which included a confidential
conditional commitment by SAT to purchase a limited fixed number of XP4 products
in various frequencies and configurations from the Company for an initial
specified period, and thereafter a commitment to purchase a limited quantity of
XP4 products corresponding to a fixed dollar amount for a specific period. The
Master Purchase Agreement contains other provisions regarding product acceptance
testing procedures applicable to SAT's purchase commitment. Orders satisfying
SAT's purchase commitment have been placed and shipments are expected to have
been completed by the fourth quarter of 1997. On June 20, 1997, the Company and
SAT amended the Cooperation Agreement to expand certain of SAT's development and
manufacturing rights, to modify the terms of sale between the parties, and to
add a confidential conditional commitment by SAT to purchase a specified dollar
amount of XP4 products within a specified period. The Company's sales of XP4
products to SAT were $3,352,000 in the six months ended June 30, 1997.
    
 
   
Sales to Bachow Communications
    
 
   
     During the fiscal period ended December 31, 1996, the Company sold XP4
radios and other equipment with an aggregate purchase price of $212,000 to
Bachow Communications, Inc. Paul S. Bachow, a director of the Company, is the
sole shareholder and President of Bachow Communications.
    
 
   
Compensation to Bachow & Associates for Acting CEO's Services.
    
 
   
     In May 1996, Bachow & Associates received $217,500 for the services
provided by Brian Flynn, formerly a Managing Director of Bachow & Associates,
who served as the acting Chief Executive Officer of the Company from January
1995 to February 1996.
    
 
   
Policy Concerning Transactions with Related Parties
    
 
   
     The Company has adopted a policy prohibiting transactions with its
directors, officers or controlling shareholders or their affiliates other than
those that result from competitive bidding or that a majority of the Company's
disinterested directors conclude are expected to benefit the Company and are on
terms no less favorable to the Company than could be obtained in arm's-length
transactions with unaffiliated third parties.

                          DESCRIPTION OF CAPITAL STOCK
 
     Upon completion of the Offering, the authorized capital stock of the
Company will consist of 30,000,000 shares of Common Stock and 5,000,000 shares
of Preferred Stock.
 
COMMON STOCK
 
   
     As of July 8, 1997, 9,639,006 shares of Common Stock were outstanding and
were held of record by 84 shareholders. Holders of Common Stock are entitled to
one vote per share on all matters submitted to a vote of the shareholders and do
not have the right to cumulate votes with respect to elections of directors.
Accordingly, holders of a majority of the shares of Common Stock voting in any
election of directors will have the ability to elect all of the directors
standing for election. All directors hold office until the next annual meeting
of shareholders and until their successors have been duly elected and qualified.
Directors may be removed with or without cause by the holders of a majority of
the outstanding shares of Common Stock.
    
 
     Holders of Common Stock are entitled to receive ratably any dividends as
may be declared by the Board of Directors out of legally available funds,
subject to any preferences that may be afforded to any outstanding preferred
stock. In the event of a liquidation, dissolution or winding up of the Company,
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of liabilities and the liquidation preference of any outstanding
preferred stock. Holders of Common Stock have no preemptive, subscription,
redemption or conversion rights. All of the outstanding shares of Common Stock
are, and all shares of Common Stock to be outstanding upon consummation of the
Offering will be, when issued and paid for, fully paid and nonassessable. The
Company's Articles of Incorporation and Bylaws provide for release and
indemnification of the Company's directors and officers as to certain
liabilities arising from their actions in such capacities to the fullest extent
permitted by law.
 
PREFERRED STOCK
 
     The Board of Directors has the authority to issue 5,000,000 shares of
preferred stock in one or more series and to fix the relative rights,
preferences and privileges thereof, including dividend rights, conversion
rights, voting rights, redemption terms, liquidation preferences and number of
shares constituting any series up to the maximum number of preferred stock. The
market price for the Common Stock, and the voting and other rights of the
holders thereof, may be adversely affected by the rights, preferences and
privileges accorded to any preferred stock issued by the Company. Issuances of
preferred stock in certain circumstances may also have the effect of delaying,
deferring or preventing a change in control of the Company, or discouraging bids
for the Company's Common Stock at a premium over the market price. Upon
consummation of the Offering, the Company will have no shares of preferred stock
outstanding. The Company has no present plans to issue any preferred stock.

CERTAIN VOTING AND OTHER MATTERS
 
     Under the Washington Business Corporation Act (the "Act"), shareholder
approval is required in order for the Company to participate in certain mergers
and share exchanges or to sell substantially all of its assets, and for certain
other actions. Within certain limits, the Act permits a corporation's articles
of incorporation to specify the level of shareholder approval required for such
transactions. The Company's Articles of Incorporation generally require any such
transaction to be approved by the holders of a majority of the outstanding
shares of Common Stock.
 
                                       57
<PAGE>   60
 
     Under the Company's Articles of Incorporation and Bylaws, special meetings
of the shareholders may be called only by the Board of Directors, the Chairman
of the Board, or the President, or the holders of at least 25% of all the votes
entitled to be cast on any issues proposed to be considered at such special
meeting. Amendments to the Articles of Incorporation must generally be approved
by the Board of Directors and the holders of a majority of the outstanding
shares of Common Stock.
 
   
     The Company's Bylaws provide that shareholders seeking to bring business
before, or to nominate directors at, any meeting of shareholders must provide
timely notice thereof in writing. To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive office of the
Company not less than 70 days prior to the date of the meeting, or the tenth day
after notice of the meeting is first given to shareholders, whichever is later
if the meeting is an annual meeting or a special meeting at which directors are
to be elected. The Bylaws also contain specific requirements for the form of a
shareholder's notice. These provisions may preclude or may make it difficult for
some shareholders from bringing matters before the shareholders or from making
nominations for directors. The Bylaws may be amended or repealed by the Board of
Directors or by the majority of the holders of the outstanding shares of Common
Stock.
    
 
   
     Holders of shares of preferred or other capital stock hereafter issued by
the Company may also be entitled to vote in connection with the matters
described above, and separate approval may be required to the extent of any
class voting rights accorded to the holders of such other stock. It is possible
that the provisions of the Company's Articles of Incorporation and Bylaws
described above may have the effect of delaying, deterring or preventing a
takeover or change in control of the Company.
    
 
ANTITAKEOVER RESTRICTIONS
 
   
     Washington law contains certain provisions that may have the effect of
delaying, deferring or preventing a takeover or change of control of the Company
which is not supported by the Board of Directors. Chapter 23B.19 of the
Washington Business Corporation Act prohibits the Company, with certain
exceptions, from engaging in certain significant business transactions with an
"acquiring person" (defined as a person who acquires 10% or more of the
Company's voting securities without the prior approval of the Company's Board of
Directors) for a period of five years after such acquisition. The prohibited
transactions include, among others, a merger with, disposition of assets to, or
issuance or redemption of stock to or from, the acquiring person, or otherwise
allowing the acquiring person to receive any disproportionate benefit as a
shareholder. The Company may not exempt itself from coverage of this statute.
These statutory provisions may have the effect of delaying, deferring or
preventing a takeover or change in control of the Company.

be outstanding, assuming no exercise of outstanding stock options or warrants to
purchase Common Stock (12,514,006 shares if the Underwriters' over-allotment
option is exercised in full), of which the 2,500,000 shares offered hereby
(2,875,000 shares if the Underwriters' over-allotment option is exercised in
full) will be freely tradable on the public market without restriction or
further registration under the Securities Act, except to the extent such shares
are held by an "affiliate" of the Company as such term is used under the
Securities Act. The remaining 9,639,006 shares were issued and sold by the
Company in private transactions, and public sale thereof is restricted except to
the extent they are registered under the Securities Act or sold in accordance
with an exemption from such registration. Shareholders who will hold an
aggregate of 9,549,177 shares of Common Stock after this offering have the right
to require the Company to register their shares for sale under the Securities
Act. Sales of substantial numbers of shares of Common Stock in the public market
following this offering could materially adversely affect the market price for
the Common Stock. See "Shares Eligible for Future Sale."
    
 
   
     Of the remaining 9,639,006 outstanding shares, 444,629 shares will be
eligible for public sale immediately after this offering pursuant to Rule 144
and 9,175 shares will be eligible for public sale 90 days after the date of this
prospectus. Certain shareholders have executed Lock-Up Agreements restricting
resale of 9,168,728 shares of Common Stock owned by them for a period of 180
days after the effective date of the Offering without the prior written consent
of UBS Securities LLC, with some exceptions. See "Underwriting." Upon the
expiration of the Lock-Up Agreements, 7,719,666 of these shares will be eligible
for immediate sale to the public under Rule 144. As of July 21, 1997, options to
purchase 1,709,517 shares of Common Stock were outstanding. Of the 633,458
shares issuable upon exercise of outstanding vested stock options as of July 21,
1997, 456,188 will be subject to the Lock-Up Agreements. Upon expiration of the
Lock-Up Agreements, all such shares, plus any additional shares purchased
pursuant to options that have vested during the Lock-Up period, will be eligible
for immediate public sale. An additional 2,949,137 shares of Common Stock are
currently issuable upon exercise of warrants outstanding at June 30, 1997. Of
these shares, 2,907,233 shares are subject to Lock-Up Agreements.
    
 
   
     In general, Rule 144 as currently in effect provides that any person who
has beneficially owned shares for at least one year, including an "affiliate"
(as defined in Rule 144), is entitled to sell, within any three-month period, a
number of shares that does not exceed the greater of 1% of the shares of Common
Stock then outstanding or the reported average weekly trading volume of the
Common Stock during the four calendar weeks immediately preceding the date on
which notice of the sale is sent to the Securities and Exchange Commission (the
"SEC"). Sales under Rule 144 are subject to certain manner of sale restrictions,
notice requirements and availability of current public information concerning
the Company. A person who is not an affiliate of the Company, and who has not
been an affiliate within three months prior to the sale, generally may sell
shares without regard to the limitations of Rule 144 provided that the person
has held such shares for a period of at least two years.
    
 
     Any employee, director or officer of, or consultant to, the Company holding
shares purchased pursuant to a written compensatory plan or contract (including
options) entered into prior to the Offering is entitled to rely on the resale
provisions of Rule 701, which permit nonaffiliates to sell such shares without
having to comply with the public information, holding period, volume limitation
or notice requirements of Rule 144 and permit affiliates to sell their Rule 701
shares without having to comply with the holding period restrictions of Rule
144, in each case commencing 90 days after the date of this Prospectus.
 
     Prior to the Offering, there has been no public market for the Common Stock
of Company and no prediction can be made of the effect, if any, that the sale or
availability for sale of shares of Common Stock will have on the market price of
the Common Stock. Nevertheless, sales of substantial amounts of such shares in
the public market could adversely affect the market price of the Common Stock.
 
OUTSTANDING REGISTRATION RIGHTS
 
   
     Under a Registration Agreement dated as of May 26, 1994, as amended on
April 26, 1996, April 30, 1997, and June 13, 1997 (the "Registration Rights
Agreement"), the holders of an aggregate of 9,549,177 shares of Common Stock
issuable upon the conversion of the Preferred Stock at the closing of the
Offering ("Registrable Securities") have certain rights as to the registration
of their shares of Common Stock under the Securities Act of 1933. Holders of
Registrable Securities have the right at any time and from time to time after
the consummation of the Offering: (i) to
    
 
                                       59
<PAGE>   62
 
   
demand registrations under the Securities Act of all or a part of the
Registrable Securities held by them on Form S-1 or any similar form; (ii) to an
unlimited number of demand registrations on Form S-2 or Form S-3 (or any
equivalent successor form) if the anticipated aggregate offering price of the
Registrable Securities covered by such form exceeds $1,000,000; (iii) in the
case of any demand registration, to select the investment bankers and managers
of the offering, subject to the Company's approval; and (iv) to have shares of
Common Stock constituting Registrable Securities held by them included in any
registration statement filed by the Company, subject to certain limitations, and
provided that such shares cannot be sold publicly without registration or
compliance with Rule 144 and to the pro rata exclusion of their shares from a
primary offering by the Company if the managing underwriters for the primary
offering advise the Company in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number
which can be sold in such offering.
    
 
     The Registration Rights Agreement requires the Company to pay all expenses
incident to its performance of or compliance with the Agreement other than
underwriting discounts and commissions allocable to the sale of a holder's
securities and the fees and expenses of the holder's own counsel, accountants
and other professional advisors.
 
   
     Registrable Securities cease to be Registrable Securities when they have
been distributed to the public pursuant to an offering registered under the
Securities Act or sold to the public through a broker, dealer or market maker in
compliance with Rule 144. No holders of registration rights under the
Registration Rights Agreement have exercised their registration rights with
respect to the Offering.

     The Underwriting Agreement provides that the Underwriters' obligations are
subject to certain conditions precedent, including the absence of any material
adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel. The nature
of the Underwriters' obligation is such that they are committed to purchase all
of the shares of Common Stock offered hereby (other than those covered by the
over-allotment option described below) if any such shares are purchased.
 
     The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock directly to the public at the offering price
set forth on the cover page of this Prospectus, and to certain dealers at such
price less a commission not exceeding $          per share. The Underwriters may
allow and such dealers may reallow, a concession not in excess of $          per
share to certain other dealers. After the public offering of the shares of
Common Stock the offering price and other selling terms may be changed by the
Underwriters.
 
     The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to 375,000
additional shares of Common Stock to cover over-allotments, if any, at the
public offering price set forth on the cover page of this Prospectus. To the
extent that the Underwriters exercise this option, each of the Underwriters will
have a firm commitment to purchase approximately the same percentage thereof
which the number of shares of Common Stock to be purchased by it shown in the
above table bears to the total number of shares of Common Stock offered hereby.
The Company will be obligated, pursuant to the option, to sell such shares to
the Underwriters to the extent the option is exercised.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
   
     All officers, directors and significant shareholders and substantially all
other shareholders of the Company, have agreed not to sell, offer to sell,
solicit an offer to buy, contract to sell, grant any option to purchase,
contract to require any other person to purchase, or otherwise transfer or
dispose of any interest in, any shares of capital stock of the Company, or any
securities convertible into or exercisable or exchangeable for capital stock of
the Company, for a period of 180 days after the date of this Prospectus without
the prior written consent of UBS Securities LLC, except for (i) securities
donated as charitable contributions which qualify as such under Section 170 of
the Internal Revenue Code of 1986, as amended, (ii) securities given by a
shareholder to members of such shareholder's "immediate family" (as such term is
defined under Item 404 of Regulation S-K under the Securities Act of 1933, as
amended), or transferred by such shareholder to one or more trusts established
for the benefit of members of such shareholder's immediate family, and (iii)
securities disposed of by the laws of testamentary or intestate descent or
pursuant to a final and non-appealable order of a court or other body of
competent jurisdiction; provided that, the shareholder may exercise presently
outstanding options, warrants or rights so long as he does not transfer the
shares obtained in violation of the Lock-Up Agreement. The Company has agreed
that it will not, until 180 days following the date of this Prospectus, without
the prior written consent of the UBS Securities LLC, sell, offer or agree to
sell, contract to sell, grant any option to purchase, make any short sale or
otherwise dispose of any shares of Common Stock, except that the Company
    
 
                                       61
<PAGE>   64
 
may grant additional options and issue stock under the 1990 Stock Option Plan
and the Director Plan or issue shares of Common Stock upon the exercise of
outstanding stock options and warrants.
 
     The Representatives have informed the Company that the Underwriters do not
intend to make sales to any accounts over which they exercise discretionary
authority.
 
     Prior to this Offering, there has been no public market for the Common
Stock. The initial price to public will be determined by agreement between the
Company and the Representatives. In determining the initial price to public, the
Company and the Representatives will consider, among other things, the history
of and prospects for the industry in which the Company operates, past and
present operations and earnings of the Company and the trend of such earnings,
the qualifications of the Company's management, the general condition of the
securities markets at the time of the Offering and the market prices for other
publicly traded companies.
 
     The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the Offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions or the imposition of penalty bids, which may have the effect of
stabilizing or maintaining the market price of the Common Stock at a level above
that which might otherwise prevail in the open market. A "stabilizing bid" is a
bid or the purchase of the Common Stock on behalf of the Underwriters for the
purpose of fixing or maintaining the price of the Common Stock. A "syndicate
covering transaction" is the bid for or the purchase of the Common Stock on
behalf of the Underwriters to reduce a short position incurred by the
Underwriters in connection with the Offering. A "penalty bid" is an arrangement
permitting the Representatives to reclaim the selling concession otherwise
accruing to an Underwriter or syndicate member in connection with the Offering
if the Common Stock originally sold by such underwriter or syndicate member is
purchased by the Representatives in a syndicate covering transaction and has
therefore not been effectively placed by such Underwriter or syndicate member.
The Representatives have advised the Company that such transactions may be
effected on the Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.
 
                                 LEGAL MATTERS
 
     The validity of the Common Stock being offered hereby will be passed upon
for the Company by Graham & James LLP, Seattle, Washington. Certain legal
matters in connection with the Offering will be passed upon for the Underwriters
by Drinker Biddle & Reath LLP, Philadelphia, Pennsylvania.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Innova Corporation:
 
     We have audited the accompanying consolidated balance sheets of Innova
Corporation and subsidiary as of March 31, 1996 and December 31, 1996, and the
related consolidated statements of operations, stockholders' deficit, and cash
flows for each of the years in the two-year period ended March 31, 1996 and for
the nine month fiscal period ended December 31, 1996. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Innova
Corporation and subsidiary as of March 31, 1996 and December 31, 1996, and the
results of their operations and their cash flows for each of the years in the
two-year period ended March 31, 1996 and for the nine month fiscal period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                   ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
    
 
 (1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     (A) NATURE OF BUSINESS
 
     Innova Corporation (Company) was formed to develop, manufacture and market
communication systems utilizing conical horn technology. In November 1993, the
Company shipped the first production units of the point-to-point radios. In
November 1994, the Company discontinued manufacture for its own account of the
original radio line; however, production of this product was continued under a
"Processor For Hire Agreement" for the account of one of Innova's stockholders
[see note 7(a), Related Party Transactions] until approximately March 31, 1996.
Also in 1994, a program to redesign the original radios was launched. The
redesign program was undertaken due to changing market demands. For the period
from January 17, 1989 (inception) through March 31, 1996, the Company was
considered to be in the development stage as the Company had not generated
significant revenues from its research and development efforts and "Processor
For Hire Agreement" and operations had been financed primarily through the
issuance of equity securities. Subsequent to March 31, 1996, the Company
effected a change in its year-end to December 31. During the nine month fiscal
period ended December 31, 1996, the Company began manufacturing and selling
redesigned radios and emerged from the development stage.
 
     (B) PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the Company and its
wholly-owned subsidiary, Innova Europe Limited.
 
     Innova Europe Limited was formed to sell products developed and
manufactured by the Company to customers in Europe. All significant intercompany
balances and transactions have been eliminated in consolidation.
 
     (C) CASH EQUIVALENTS
 
     The Company considers all short-term investments with a maturity of three
months or less at date of purchase to be cash equivalents.
 
     (D) INVENTORIES
 
     Inventories are stated at the lower of cost (first-in, first-out) or market
(net realizable value).
 
     (E) DEPRECIATION AND AMORTIZATION
 
     Depreciation of equipment and amortization of leasehold improvements is
provided on the straight-line method over the estimated useful lives of the
assets which range from two to five years, not to exceed lease terms for
leasehold improvements.
 
     (F) PATENTS
 
     The Company has filed several patent applications in the United States and
other countries. Costs associated with filing patent applications are expensed
as incurred.
 
     (G) RESEARCH AND DEVELOPMENT COSTS
 
     Research and development costs are charged to expense as incurred.
Statement of Financial Accounting Standards No. 86, Accounting for the Costs of
Computer Software to be Sold, Leased or Otherwise Marketed, requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility.

                   ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
    
 
     Based on the Company's product development process, software development
costs incurred by the Company between the establishment of technological
feasibility and the point at which the product is ready for general release have
not been significant.
 
     (H) REVENUE RECOGNITION
 
     The Company recognizes revenue on product sales upon shipment. The Company
provides certain service and support for its products and accrues for the
estimated amount of these costs at the time of sale. These costs have not been
significant through December 31, 1996. Under the Processor For Hire
Agreement -- (PFHA) as discussed in note 7(a), manufacturing contract service
revenues were recognized as the services were performed.
 
     (I) INCOME TAXES
 
     Deferred income tax assets and liabilities are computed for differences
between the financial statement and tax basis of assets and liabilities that
will result in taxable or deductible amounts in the future based on enacted tax
laws and rates applicable to the periods in which the differences are expected
to affect taxable income. Valuation allowances are established for deferred tax
assets to the extent there is uncertainty regarding the Company's ability to
generate taxable income in the future and when it is more likely than not that
such deferred tax assets will not be realized. Income tax expense is the tax
payable or refundable for the period plus or minus the change during the period
in net deferred tax assets and liabilities.
 
     (J) FOREIGN CURRENCY TRANSLATION
 
     Assets and liabilities of Innova Europe Limited have been translated to
U.S. dollars using rates of exchange in effect at the end of the fiscal year.
Income and expense accounts have been translated to U.S. dollars using annual
average rates of exchange. The net gain or loss resulting from translation is
shown as a cumulative translation adjustment in stockholders' equity.
 
     (K) RECLASSIFICATIONS
 
     Certain reclassification amounts have been made to the March 31, 1995 and
1996 balances to conform to the December 31, 1996 presentation.
 
     (L) CONCENTRATION OF CREDIT RISK AND SUPPLIER CONCENTRATION
 
     The Company currently purchases an important component of its products from
two principal suppliers. Although there are a limited number of potential
manufacturers of such component, management believes that other suppliers could
provide similar components on comparable terms. A change in suppliers, however,
could cause a delay in manufacturing and a possible loss of sales, which could
have a material adverse effect on the manufacturing and delivery of the
Company's products. Purchases from these principal suppliers were as follows:

     (M) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF
 
     The Company adopted the provisions of Statement of Financial Accounting
Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of, on April 1, 1996. This Statement requires
that long-lived assets and certain identifiable intangibles be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets
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. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell. Adoption of this Statement did not have
a material impact on the consolidated financial statements.
 
     (N) PRODUCT WARRANTIES
 
     The Company provides warranties which generally last for two years, on the
products that it sells. The provision for warranty expense is based on
historical industry and Company experience and is accrued when products are
sold.
 
     (O) STOCK-BASED COMPENSATION
 
     The Company accounts for its stock-based compensation arrangement in
accordance with the provisions of Accounting Principles Board (APB) Opinion No.
25, Accounting for Stock Issued to Employees, and related interpretations. As
such, compensation expense under fixed plans would be recorded on the date of
grant only if the fair value of the underlying stock at the date of grant
exceeded the exercise price. Statement of Financial Accounting Standard (SFAS)
No. 123, Accounting for Stock-Based Compensation, requires entities that
continue to apply the provisions of APB Opinion No. 25 for transactions with
employees to provide pro forma net income and pro forma earnings per share
disclosures for employee stock option grants made in 1995 and future years as if
the fair-value-based method defined in SFAS No. 123 had been applied to these
transactions.
 
     (P) UNAUDITED INTERIM FINANCIAL STATEMENTS
 
   
     In the opinion of the Company's management, the June 30, 1997 and 1996
unaudited interim financial statements include all adjustments consisting only
of normal recurring adjustments, necessary for a fair presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
   
            (INFORMATION AS OF JUNE 30, 1997 AND FOR THE SIX MONTHS
    
   
                   ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
    
 
     (Q) PRO FORMA NET LOSS PER SHARE
 
   
     Pro forma net loss per share is computed by dividing net loss by the
weighted average number of shares of common stock and common stock equivalents
outstanding during each period and the shares resulting from the conversion of
all outstanding shares of preferred stock at the closing of the IPO. Common
stock equivalents include all warrants and stock options which would have a
dilutive effect, applying the treasury stock method. Additionally, common and
common equivalent shares issued during the twelve months immediately preceding
the initial filing of the Company's initial public offering have been included
in the calculation of common and common equivalent shares as if they were
outstanding for all periods presented, including loss years where the impact of
the incremental shares is antidilutive, using the treasury stock method and an
assumed initial public offering price of $11 per share. Due to the significant
impact of the assumed conversion of the redeemable preferred stock upon closing
of the IPO, historical net loss per share is not meaningful and is therefore not
presented.
    
 
   
     Supplementary net loss per share is $(0.72) and $(0.27) for the nine month
fiscal period ended December 31, 1996 and the six months ended June 30, 1997,
respectively.
    
 
   
     The calculation of supplementary net loss per share assumes that notes
payable outstanding at the beginning of the periods presented were retired with
proceeds from the issuance of common stock. The number of shares of common stock
the proceeds of which were used to retire the notes payable are included in the
calculation.
    
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, Earnings Per Share, (Statement 128).
This statement establishes standards for the computation, presentation and
disclosure of earnings per share (EPS), replacing the presentation of currently
required Primary EPS with a presentation of Basic EPS. It also requires dual
presentation of Basic EPS and Diluted EPS on the face of the income statement
for entities with complex capital structures. Basic EPS is based on the
weighted-average number of common shares outstanding during the period. Diluted
EPS is based on the potential dilution that would occur, upon exercise or
conversion of securities into common stock using the treasury stock method.
Statement 128 is effective for financial statements for periods ending after
December 15, 1997, including interim periods, and earlier application is not
permitted. When adopted, the Company will be required to restate its EPS data
for all prior periods presented. The Company does not expect the impact of the
adoption of this statement to be material to previously reported EPS amounts.
 
 (2) USE OF ESTIMATES
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 (5) NOTES PAYABLE
 
   
     In October 1996, the Company entered into a $5 million revolving credit
agreement which bears interest at the LIBOR rate plus 4.875% with a minimum of
8% per annum (10.545% at December 31, 1996 and 10.595% at June 30, 1997).
Amounts outstanding were $0, $506,180, and $4,118,236 at March 31, 1996,
December 31, 1996 and June 30, 1997, respectively. Under the terms of the

terms. In April 1997, the Company amended the credit agreement to include an
additional term loan for $1,500,000 due on the earlier of:
 
          (a) April 30, 1998;
 
          (b) the date the initial October 1996 revolving credit agreement
     terminates; or
 
          (c) the date the Company first issues equity, debt or other
     securities, other than the Series F financing discussed in note 17,
     subsequent to April 1997.
 
   
     Interest is payable monthly with interest at the LIBOR rate plus 4.875%
with a minimum of 8% per annum. In connection with the term loan, the Company
issued to the lender a warrant to purchase 21,500 shares of the Company's common
stock, at $6.96 per share. The warrant expires in April 2003. The estimated
value of the warrant $67,400, was recorded as debt discount and is being
amortized to interest expense over the period that the debt is outstanding.

 (7) RELATED PARTY TRANSACTIONS
 
     (A) SALES, MANUFACTURING AND SERVICE REVENUES
 
   
     Sales totaling approximately $212,000 were made to the Company's major
stockholder during the nine month fiscal period ended December 31, 1996.
    
 
     Substantially all of the total revenues recorded in the year ended March
31, 1996 were to a stockholder of the Company, Societe Anonyme de
Telecommunications (SAT). In November 1994, the Company entered into an
agreement [Processor For Hire Agreement -- (PFHA)] with SAT whereby SAT
purchased substantially all of the Company's inventories as of November 1994 for
cash. The PFHA called for the Company to continue to manufacture radios for SAT;
however, SAT was responsible for supplying the materials used in the manufacture
of these radios. Under the PFHA, SAT reimbursed the Company for the costs
incurred by the Company in the assembly and testing of the radios. In addition,
SAT paid to the Company a fee to cover administrative costs plus a profit. This
fee was based on the volume of materials purchased for SAT for the production of
the radios. The Company managed all of the manufacturing and purchasing
functions associated with the manufacture of radios and the purchase of radio
components. The PFHA was substantially terminated as of March 31, 1996.
 
     The reimbursement of the costs of manufacture along with the administration
fee during the fiscal year ended March 31, 1995 and 1996 and the nine month
fiscal period ended December 31, 1996 have been recorded as manufacturing
contract service revenues in the consolidated statements of operations. The
identifiable costs associated with the manufacture of the radios covered by the
PFHA have been summarized in the consolidated statements of operations as
manufacturing contract service expenses.

     Product sales made to SAT for the nine month fiscal period ended December
31, 1996 were approximately $3,000 and for the six months ended June 30, 1997
were approximately $3,532,000.
    
 
     (B) ACCOUNTS RECEIVABLE
 
   
     Accounts receivable due from SAT were $76,523, $58,283 and $2,641,717 at
March 31, 1996, December 31, 1996 and June 30, 1997, respectively.
    
 
     (C) MANDATORILY CONVERTIBLE NOTES PAYABLE FOR PREFERRED STOCK, STOCK
         SUBSCRIPTIONS RECEIVABLE AND RELATED EQUITY TRANSACTIONS
 
   
     On March 27, 1996, the Company entered into stock subscription agreements
with certain existing stockholders for the purpose of selling Series D preferred
stock for an aggregate price of $7,000,000. The $7,000,000 includes $1,000,000
in unsecured notes payable to stockholders issued in November and December 1995
as discussed in the following paragraph. As of March 31, 1996, proceeds of
$3,702,219 net of offering costs of $15,910, had been received by the Company
related to the stock subscription agreements. The remaining $3,281,871 was
received during the nine month fiscal period ended December 31, 1996.
Mandatorily convertible notes payable were issued as the cash was received by
the Company. Mandatorily convertible notes payable accrued interest at 16%
annually and were convertible into Series D preferred shares at the earlier of a
"qualified financing" event or April 26, 1996. A "qualified financing" event, as
defined in the stock subscription agreements, was consummated on April 26, 1996
when the Company issued 1,548,940 shares of Series D preferred stock, at $3.228
per share to a new stockholder for proceeds of $4,953,121. The mandatorily
convertible notes payable outstanding at April 26, 1996 were then converted into
2,168,523 shares of Series D preferred stock at $3.228 per share, and contingent
common stock purchase warrants (contingent upon the pricing of the "qualified
financing" event) totaling 367,082 with an exercise price of $0.024 per share,
were issued to the former holders of the mandatorily convertible notes payable.
No separate value has been assigned to the warrants as the value was not
significant at the date of issuance.
    
 
     Unsecured notes payable to stockholders were issued in November and
December 1995 totaling $1,000,000, bearing interest at rates ranging from
16%-21%. In connection with these notes, 193,611 warrants were issued to
purchase common stock for $2.5824 per share which expire April 26, 2001. No
separate value has been assigned to the warrants as the value was not
significant at the date of issuance. On March 27, 1996, these unsecured notes
payable were exchanged for mandatorily convertible notes payable as part of the
stock subscription agreements described above.
 
   
     Interest expense on unsecured borrowings from stockholders amounted to
$79,357, $107,648, $70,101 and $62,934 for the years ended March 31, 1995 and
1996, the nine month fiscal period ended December 31, 1996 and the six months
ended June 30, 1997, respectively.
    
 
     In November 1996, the Company issued $1,500,000 in unsecured 12%
convertible promissory notes payable to stockholders, which were subsequently
repaid by notes which in turn were converted into Series E preferred stock in
March 1997.
 
     (D) COMPENSATION EXPENSE
 
     In May 1996, the Company paid a representative of a stockholder $217,500
for services rendered from January 1995 to February 1996, who served as the
acting Chief Operating Officer of the Company.

common shares at any time, are automatically convertible upon the consummation
of an initial public offering (IPO), have certain liquidation and dividend
preferences over common shares, and also have certain antidilution rights. The

     The Company has a stock option plan (Plan) to compensate key employees,
consultants and vendors for past and future services and has authorized a total
of 1,458,333 shares of common stock to be reserved for grants. In the first
quarter of 1997, a plan amendment was approved increasing shares available for
grant by 125,000 bringing the total authorized to 1,583,333. Options may be
granted under the Plan as either incentive stock options or as nonqualified
stock options.
 
     Incentive stock options may be granted at prices not less than fair market
value of the stock, generally are exercisable based on continued employment over
a five-year period in equal increments each year beginning one year from the
date of grant, and expire ten years from the date of grant. The Company has
granted no incentive stock options to date.
 
     Nonqualified options may be granted at prices determined by the Company and
generally expire twenty years from the date of grant. The options vest and
become exercisable over one to four years in cumulative increments beginning one
year from the date of grant. A distinction is made between nonqualified time
vesting and nonqualified time and performance vesting options. Nonqualified time
and performance vesting options require the attainment of certain performance
goals in addition to the passage of time prior to vesting.
 
     In accounting for the options requiring the attainment of certain
performance goals, the Company must include a determination of compensation cost
at the end of each period if the market value of the shares of the Company's
stock exceeds the exercise price. Any compensation cost shall be charged to
expense over the periods the employee performs the related service. During the
first quarter in 1997, the Company amended the terms of 460,633 stock options by
eliminating the performance criteria. The table below reflects these performance
options as being amended to time

vesting. The Company has recorded deferred stock option compensation totaling
$1,279,900 and $309,377 during the first and second quarters in 1997,
respectively. The first quarter of 1997 deferred stock option compensation
relates principally to the 460,633 options with performance goals outstanding
prior to the elimination of the performance criteria. In addition, the deferred
stock option compensation includes some amounts recorded for nonqualified time
vesting grants where the estimated market value of the shares of the Company's
stock exceeded the exercise price at the date of the grant. The estimated market
value of the Company's common stock used in calculating the majority of the
deferred stock option compensation was approximately $4.32 per share. The second
quarter of 1997 deferred stock option compensation relates principally to the
authorization by the Board of Directors for the future grant of 56,250 options
to employees that vest upon the attainment of certain performance goals. In June
1997, the Company amended the terms of these future stock option grants by
eliminating the performance criteria. The 56,250 options are not reflected in
the table below as they have not been granted. The exercise price of these
options range from $4.60 to $6.00 per share.
    
 
     A summary of nonqualified time vesting and time and performance vesting
stock options is as follows:

     The Company applies APB Opinion No. 25 in accounting for its Plans, and no
compensation cost for the years ended March 31, 1995 and 1996 and the nine month
fiscal period ended December 31, 1996 has been recognized for its employee stock
options in the consolidated financial statements. Had the Company determined
compensation cost of employee stock options based on the fair value at the grant
date for its stock options under SFAS No. 123, the Company's pro forma net loss
would not have been significantly different than the reported net loss.
 
     The weighted-average fair value per share of the grants made during the
year ended March 31, 1996 and the nine month fiscal period ended December 31,
1996 was approximately $0.02 and $0.054 respectively. The fair value of the
stock options granted was estimated on the date of grant using the Black Scholes
option-pricing model with the following weighted-average assumptions: for the
year ended March 31, 1996 -- expected dividend yield 0%, risk-free

(10) EMPLOYEE BENEFIT PLAN
 
   
     In January 1996, the Company implemented a 401(k) plan that covers all
employees who satisfy certain eligibility requirements relating to minimum age,
length of service and hours worked. Under the profit sharing portion of the
plan, the Company may make an annual contribution for the benefit of eligible
employees in an amount determined by the Board of Directors. As of June 30,
1997, the Company had not made any contributions to the plan. Under the 401(k)
portion of the plan, eligible employees may make pretax elective contributions
of up to 10% of their compensation, subject to maximum limits on contributions
prescribed by law.
    
 
(11) INCOME TAXES
 
     The Company has not recorded an income tax benefit for the years ending
March 31, 1995 and 1996, and the nine month fiscal period ended December 31,
1996 due to the recording of a valuation allowance as an offset to net deferred
tax assets. A valuation allowance is provided due to uncertainties relating to
the realization of deferred tax assets.

Kingdom taxable income, if any, of approximately $1.8 million expiring in 2006
through 2011.
 
     The utilization of the tax net operating loss carryforwards may be limited
due to ownership changes that have occurred as a result of the sale of common
and preferred stock.

     The Company is obligated under various capital leases for certain equipment
that expire at various dates during the next three years. The Company also has
certain noncancelable operating leases that expire over the next two years and

                                 AND SUBSIDIARY
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
   
            (INFORMATION AS OF JUNE 30, 1997 AND FOR THE SIX MONTHS
    
   
                   ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
    
 
(14) OPERATIONS AND FINANCING
 
     The Company's consolidated financial statements have been prepared on a
going concern basis.
 
   
     The Company incurred a net loss of $7,328,836, had negative cash flows from
operations of $9,550,621, and an accumulated deficit of $40,374,903 as of and
for the nine month fiscal period ended December 31, 1996. The Company has
expended a significant amount of cash in developing its technology and
redesigned radios and during the nine month fiscal period ended December 31,
1996, the Company commenced principal operations. The Company expects to expand
its manufacturing and sales efforts during 1997 and to reach profitable levels
during 1997. Although, as of June 1997, the Company has a significant sales
order backlog, and is successfully manufacturing its redesigned radios,
management recognizes that to sustain the rate of growth projected and to meet
working capital requirements, additional resources may be necessary.
Accordingly, in March 1997, the Company closed a Series E preferred stock
financing transaction totaling $5 million. Included in the $5 million financing
was the conversion of unsecured convertible promissory notes payable to
stockholders. Additional financing is discussed in note 17. In addition, the
Company has retained investment banking counsel to advise it on the possible
sale of additional equity securities in connection with a proposed IPO. The
Company intends to offer for sale, as part of the IPO, 2,500,000 shares of
common stock at a price ranging from $10 to $12 per share.
    
 
     Management expects that these efforts will result in adequate near term
financing. No assurances can be given that the Company will achieve
profitability or positive cash flow.
 
(15) CONTINGENCIES
 
     The Company is subject to various legal proceedings and claims which have
arisen in the ordinary course of its business. These actions when ultimately
concluded and determined will not, in the opinion of management, have a material
effect on results of operations or the financial condition of the Company.
 
(16) FINANCIAL INSTRUMENTS
 
     The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, accounts payable, accrued liabilities,
obligations under capital leases, notes payable and notes payable to
stockholders. The fair value of obligations under capital leases, notes payable
and notes payable to stockholders estimates their recorded values based on
current rates available to the Company. The remaining financial instruments have
a short-term until maturity or settlement in cash and, therefore, the carrying
value approximates fair value.
 
(17) SUBSEQUENT EVENTS
 
     In June 1997:
 
   
- The Board of Directors authorized the increase in the number of common shares
  to 16,666,666 and preferred shares to 13,379,164 of which 504,166 shares are
  designated as Series F Preferred Stock which have identical preferences as the
  Series C Senior Preferred, D and E Preferred, except that the liquidation
  preference is $6.96 per share. Also in June 1997, the Company issued 502,867
  shares of Series F Preferred Stock at $6.96 per share, for total cash
  consideration of $3,500,000, before issuance costs.
    
 
   
- The Board of Directors authorized a 24:1 reverse stock split on its common and
  preferred stock and eliminated the par values related thereto. In addition,
  the Board subsequently approved changes in the authorized number of preferred
  shares to 5,000,000 and common shares to 30,000,000, to be effective upon
  closing of the IPO. These consolidated financial statements and notes thereto
  have been restated for these actions.

                   ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
    
 
   
- A plan amendment to the Company's Stock Option Plan was approved increasing
  shares available for grant by 500,000 bringing the total authorized to
  2,083,333.
    
 
- The Board of Directors authorized a Stock Option Plan for Nonemployee
  Directors for which 120,000 shares of common stock were reserved for sale and
  issuance under the plan. Under the provisions of the plan, 48,263 options were
  granted with an exercise price of $9.84 per share and a vesting period of 4
  years.
 
   
- The Board of Directors amended the terms of 56,250 future stock option grants,
  discussed in footnote (9), by eliminating the performance criteria.
    
 
   
- The Board of Directors authorized management to file a registration statement
  with the Securities and Exchange Commission to permit the Company to sell
  shares of its common stock to the public. Upon completion of the Company's
  initial public offering, each outstanding share of redeemable preferred stock
  will convert into one share of common stock. Unaudited pro forma stockholders'
  equity reflects the assumed conversion of the redeemable preferred stock into
  common stock as of June 30, 1997.
    
 
   
- Prior to June 1997, certain warrants to purchase 481,977 of Series A.2
  preferred stock were outstanding. In June, 1997, the Company amended the
  warrants to provide that if the outstanding preferred shares of the Company is
  converted into common shares, the warrants will be for the purchase of 481,977
  shares of common stock.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act authorize a court to award, or a corporation's board of
directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article V, Section 5.1, of the Registrant's Second Restated
Articles of Incorporation (Exhibit 3.1 hereto) and Article X of the Registrant's
Amended and Restated Bylaws (Exhibit 3.2 hereto) provide for mandatory
indemnification of the Registrant's directors, officers, employees and agents to
the maximum extent permitted by law. (The directors and officers of the
Registrant also may be indemnified against liability they may incur for serving
in that capacity pursuant to a liability insurance policy maintained by the
Company for such purpose.)
 
     Section 23B.08.320 of the Washington Business Corporation Act authorizes a
corporation to limit a director's liability to the corporation or its
shareholders for monetary damages for acts or omissions as a director, except in
certain circumstances involving intentional misconduct, self-dealing or illegal
corporate loans or distributions, or any transaction from which the director
personally receives a benefit in money, property or services to which the
director is not legally entitled. Article V, Section 5.2, of the Registrant's
Amended and Restated Articles of Incorporation contains provisions implementing,
to the fullest extent permitted by Washington law, such limitations on a
director's liability to the Registrant and its shareholders.
 
   
     Reference is made to the Registrant's Second Restated Articles of
Incorporation, filed as Exhibit 3.1 to this Registration Statement, and the
Registrant's Amended and Restated Bylaws, filed as Exhibit 3.2 to this
Registration Statement. The provisions of the Registrant's Second Restated
Articles of Incorporation regarding indemnification of officers and directors
are substantially the same as those of Article V of the Registrant's Restated
Articles of Incorporation, to be filed as Exhibit 3.2 to this Registration
Statement.
    
 
     Reference is also made to the form of Underwriting Agreement filed as
Exhibit 1.1 to this Registration Statement for certain provisions regarding the
indemnification of officers and directors of the Registrant by the Underwriters.

ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described in Item 14 above, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes to provide to the
Underwriters, at the closing specified in the Underwriting Agreement,
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this registration statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Securities Act shall be deemed to be a part of this
     registration statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new Registration Statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
