THE NETRO SOLUTION

      We are a leading provider of wireless networking equipment used by
telecommunications service providers to provide businesses with high-speed
telecommunications connections. We believe that AirStar is a high-quality,
flexible system that allows service providers to deploy wireless
telecommunications services cost effectively and rapidly. We have engineered
AirStar to support broad service rollouts and to operate at radio frequencies
licensed for voice and high-speed data connections in different countries. We
believe that AirStar is one of the first commercially available, high-speed
wireless telecommunications systems to use a point-to-multipoint architecture in
providing integrated voice and high-speed data connections. Our AirStar system
is designed to provide the following benefits to service providers:

      SERVICE INTEGRATION AND BANDWIDTH ON DEMAND. Our AirStar system employs
our proprietary software protocol, CellMAC, which enables flexible and dynamic
sharing of capacity among a number of subscribers and services. Many existing
high-speed connection technologies are optimized for either voice or data
traffic. Voice traffic requires fixed-speed, low-capacity transmissions, while
data traffic requires variable-speed, high-capacity transmissions. Consequently,
network operators wishing to carry both types of traffic often must choose among
setting aside capacity to service peak transmission data traffic requirements,
allowing degradation of service during heavy usage, or servicing a smaller
number of subscribers. In contrast, service providers using the AirStar system
can support voice and high-speed data from the same system without these
performance compromises. Additionally, AirStar allows service providers to offer
symmetrical high-speed services, with peak transmission rates of up to 16 Mbps
to meet the needs of many business users that send and receive large files for
e-mail, application hosting, intranet access and e-commerce.

      COST-EFFECTIVE DEPLOYMENT AND OPERATION. AirStar's cost-effective
deployment allows a service provider to compete effectively in providing its
customers with high-speed telecommunications services. By employing a
point-to-multipoint architecture, one AirStar hub radio can serve multiple
subscriber radios, which results in lower total radio costs than architectures
in which each radio can only communicate with one other radio. AirStar also uses
an advanced technology that allows voice and data traffic to be transmitted in
adjacent time slots. This architecture reduces duplicate network hardware
components such as modems, and thus further lowers overall system costs. In
addition, a significant portion of the cost to build an AirStar network is
directly related to subscriber growth, allowing the service provider to incur
costs concurrently with the subscriber growth. To add subscribers in a sector, a
provider simply installs equipment at the subscriber's premises and activates
the service remotely. Finally, the AirStar system allows a service provider to
optimize the use of radio frequencies and the deployment of equipment by
expanding effective transmission capacity.

      QUALITY OF SERVICE AND RELIABILITY. Service providers using AirStar can
deploy voice and data services at different price points to different market
segments with the option for guaranteed quality of service levels and up to
99.999% availability. AirStar can prioritize transmissions depending on their
source and type, and fill available transmission capacity with lower priority
transmissions. Furthermore, the AirStar system is engineered to enable service
providers to offer the same high reliability and availability for services that
traditional service providers have historically offered for voice services.
Reliability is accomplished through an error correction algorithm, redundancy
and comprehensive network management software.

      RAPID TIME TO MARKET. Service providers using AirStar can achieve rapid
time to market for integrated voice and high-speed data connections through
AirStar's efficient installation, network management software and ability to
dynamically allocate capacity among subscribers. Service providers that we
target have typically committed a high level of capital investment to enter the
high-speed wireless telecommunications services market, and thus are focused on
quickly realizing a return on their investment. Our AirStar system is scalable
and allows service providers to rapidly offer new services to existing or
incremental subscribers within a coverage area by a simple software command and
a radio installation that is automatically configured by the base station with
little technician


                                       3
<PAGE>   4

intervention. By installing one AirStar base station, the service provider can
attain coverage of many potential subscribers. For example, a typical cell at 26
GHz, the frequency of our current highest-volume product, can cover ranges from
5 to 15 square miles, depending on local conditions, and has a transmission
capacity of over 600 Mbps. Compared to other high-speed, wire-based technologies
that often require lengthy and expensive upgrades before offering service or do
not support integrated voice and symmetrical data services, AirStar allows a
service provider to rapidly deploy integrated voice and high-speed data services
as demand warrants.

STRATEGY

      Our objective is to be the leading worldwide supplier of wireless,
high-speed equipment used by telecommunications service providers. Key elements
of our strategy include the following:

      INCREASE DEPLOYMENTS WITH SERVICE PROVIDERS WORLDWIDE. As the needs of
service providers evolve, we intend to extend product features to leverage the
success achieved at key service providers. We believe that AirStar is one of the
first commercially available, high-speed wireless systems with a
point-to-multipoint architecture. To date, service providers have deployed the
AirStar system in trials, with several commercial pilots. We intend to convert
early design wins within our existing service provider base into large-scale
commercial deployments. Once completed, we intend to utilize successful
deployments at existing service providers as reference accounts for new service
providers. We intend to expand aggressively our product marketing and
development beyond existing service providers that use the 10 GHz, 26 GHz and
38GHz frequencies and into new markets domestically and internationally to serve
a broader service provider base. For example, we expect to begin preliminary
customer testing of our 28 GHz product, allowing us to serve telecommunications
service providers that operate at this frequency in the U.S. market.

      INCREASE MANUFACTURING CAPACITY FOR LARGE SCALE DEPLOYMENTS. For large
scale deployments customers would require significantly larger quantities of
products than we are currently producing. In order to have the capacity
available to meet potential future product demands we are actively working with
our contract manufacturers to ensure that they can both scale their
manufacturing processes to meet our potential needs as well as maintain quality
standards at significantly higher volumes. We are also focused on achieving cost
reductions as we ramp our manufacturing to ensure lower product prices and costs
enable the continued development of the market. As a part of this process we
recently entered into a contract with a third contract manufacturer, NEC
America, in January of 2000. We are also selectively exploring relationships
with additional contract manufacturers.

      PROVIDE COMPETITIVE ADVANTAGES TO SERVICE PROVIDERS. We intend to continue
to focus our product development efforts on features that would enable service
providers to deploy differentiated, profitable services to their business
subscribers. The AirStar system allows service providers to deploy voice and
data services to additional subscribers rapidly and cost effectively when demand
warrants. As service providers begin to deploy AirStar on a broader basis, we
expect they will demand support for additional data and voice services and
higher-speed interfaces to increase their market share. We intend to offer new
features that will enable service providers to further differentiate their
services. For example, we expect to introduce support for additional data and
voice services and peak transmission rates of up to 26 Mbps later in 2000.

      CAPITALIZE ON TECHNOLOGY LEADERSHIP TO INTRODUCE NEW PRODUCTS RAPIDLY AND
COST EFFECTIVELY. Our AirStar platform can allocate capacity dynamically because
it integrates a number of technical capabilities, including millimeter wave
radio design, data networking and network management software. We believe
integrating these capabilities is highly complex, and we intend to leverage our
technology expertise to introduce new products and features rapidly and cost
effectively. AirStar's design enables us to reuse protocol software and many
common networking elements. As a result, the introduction of products in a new
frequency typically requires only relatively simple modifications in the radio
elements rather than the extensive development time and costs of entirely
redesigned equipment.

      BUILD SALES AND CUSTOMER ADVOCACY INFRASTRUCTURE. We believe the best way


                                       4
<PAGE>   5

to increase product sales and overall market acceptance of the AirStar system is
through the development of our own direct sales and customer advocacy
infrastructure. Our own direct sales force will allow us to reach customers who
have the ability to install, integrate, service and maintain their own systems.
Our direct sales force also helps us build long-term relationships with service
providers whether they are customers of ours or of our system integrators. We
plan to work closely with our system integrators and service providers to enable
them to provide their own primary and secondary tiers of support for the AirStar
system while our engineers and customer service personnel will provide backup
support on a 24-hour, 7-day basis. As a result, we intend to be in a position to
scale our business rapidly as service providers worldwide transition from trials
to commercial deployments.

      STRENGTHEN RELATIONSHIPS WITH LEADING COMMUNICATIONS EQUIPMENT VENDORS. We
intend to build on our success with Lucent and Siemens to meet the needs of
service providers seeking to deploy large-scale networks and to expand our
service provider base. Our relationships with these vendors enable service
providers deploying AirStar to receive services to integrate our equipment in
their network, and to receive an increased level of customer service. We believe
the provision of these services can facilitate broader deployments worldwide. We
further believe that leading communications equipment vendors with a global
sales presence are in the strongest position to provide service providers with
integration services and support. Thus, we believe strengthening these
relationships and selectively establishing new relationships will facilitate
increased volume deployments of our products in the global market.

PRODUCTS

      The AirStar system is typically deployed in a hub and spoke layout. Each
central hub can provide immediate wireless coverage of a particular area, with
the coverage area depending on the licensed frequency, local conditions and the
level of service availability chosen by the service provider. The AirStar system
consists of integrated network and millimeter wave radio components located at a
central hub and at multiple subscriber locations. AirStar components at the hub
consist of the base station and the base radio unit. AirStar components at a
subscriber's premises consist of a subscriber access system and a subscriber
radio unit. The AirView Link Explorer network management software is typically
used at the service provider's switching center, where it is used to remotely
monitor and manage the subscriber and the hub equipment. The table below shows
the coverage statistics for a typical installation and configuration of one hub
under common local conditions in the geographic regions where we expect many of
our products to be deployed.

      The base radio units at the hub site send and receive simultaneous
high-speed transmissions from multiple subscriber radio units. The system
schedules transmissions from each subscriber on a packet-by-packet basis. The
base station prioritizes the transmissions and allocates just enough bandwidth
or time slots to complete the transfer of each packet. The base station and the
subscriber access system process and manage the information transmitted by the
radio components over the air. Security of the transmissions over the air is
achieved through discrete identifiers for each of the subscriber access systems
and scrambling of the digital transmission through our air interface protocol.
This traffic is processed and delivered to the service provider's switching
center, where the voice and data traffic is connected to the public switched
telephone network for voice, and to the Internet or other public networks for
data.

TECHNOLOGY

      We believe we have developed industry-leading technologies, including
CellMAC software and hardware implementations, an advanced networking
architecture, radio transmission technology and networking software
capabilities. We first commercialized these technologies in the form of our
AirStar family of products by focusing on the service provider's needs.

      CELLMAC PROTOCOL. We believe our proprietary CellMAC protocol maximizes
the benefit of our point-to-multipoint architecture, and advanced peak traffic
management techniques. CellMAC schedules transmissions from each subscriber in
very small increments. It allows subscribers to request additional capacity from
the base station for peak demand data services through a capacity reservation
mechanism that requires little wasted radio frequency. The base station can
prioritize the requests according to service level agreements and allocates just
enough capacity or time slots to enable the transfer of each transmission.
Traffic from each subscriber terminal shares the capacity, as necessary, to
fulfill the quality of service for each subscriber.

      ASYNCHRONOUS TRANSFER MODE ARCHITECTURE. We have implemented an air
interface that utilizes asynchronous transfer mode, a communications protocol,
to efficiently combine voice and data onto a single stream. CellMAC is our
implementation of this protocol over the air. We believe that we are using the
only standardized technology that can transport voice and data traffic
simultaneously and maintain a guaranteed quality of service for each traffic
type. Using this architecture, capacity for services can be provided based on
average throughput requirements rather than peak throughput requirements. As a
result, the capacity of the transmission is increased, resulting in better use
of radio frequency and thus lower equipment expenditures.

      PEAK DEMAND MODULATION AND MILLIMETER WAVE RADIO TECHNOLOGY. Since our
inception, we have worked extensively on radio designs and volume manufacturing
processes to create robust yet cost-effective radios that support advanced radio
technology and peak demand transmission capabilities. The current AirStar radios
are our third generation design.

      SYSTEM AND SERVICES SOFTWARE. Our software architecture and use of
object-oriented design principles for both real-time and network management
software are key to making our AirStar software modular and adjustable to
additional communications protocols. Our software extends the ability of the
AirStar system to enable the inter-working of voice protocols and support the
concentration of voice traffic. In a recent software release we extended the
capabilities of the CellMAC protocol to provide dynamic allocation of capacity
to voice services.

SALES AND MARKETING

      We have sales representatives in Brazil, France, Germany and the United
Kingdom, as well as in Atlanta, Georgia and in our corporate headquarters in San
Jose, California. We sell our products through worldwide system integrators, our
direct sales force and local resellers. We have established relationships with
two leading system integrators, Lucent and Siemens. We have worked with these
system integrators in development of end-to-end network management systems and
radio planning tools. Our system integrators typically have the means to provide
vendor financing of equipment and may do so in situations where our equipment is
purchased as part of the total network. For some service providers, this
financing is a necessary part of the total solution.

      We also target key strategic accounts with our direct sales force, which
has become an increasingly important part of our sales strategy. In determining
which accounts are appropriate for direct sales, we try to identify those that
are key early adopters that can help drive our product feature sets in a manner
that will better address the needs of the marketplace as a whole. These
customers have the ability to install, integrate, service and maintain their
systems themselves. Regardless of the actual distribution channel that services
the account, our direct sales force maintains contact with the service provider
and the system integrator account team. This contact keeps us close to the
evolving needs of the service providers and helps ensure that we are well
positioned within each account. In some

                                       6
<PAGE>   7

markets, we have established distribution relationships with local resellers
that also provide support and maintenance to the service providers they cover.

      Our marketing group provides marketing support services for our executive
staff, our direct sales force and for our system integrators and resellers.
Through our marketing activities, we provide technical and strategic sales
support to our direct sales personnel and system integrators or resellers
including in-depth product presentations, technical manuals, sales tools,
pricing, marketing communications, marketing research, trademark administration
and other support functions.

      Our marketing group is also responsible for product management activities
throughout each product's lifecycle. These include the definition of product
features, approval of product releases, specification of enhancements to our
product and service offerings, and determination of future product platforms.

SYSTEM INTEGRATOR ALLIANCES

      We have established important relationships with two worldwide system
integrators to facilitate the deployment of our products and to meet the
requirements of service providers with end-to-end network integration as they
seek to deploy our high-speed wireless access solution.

      - Lucent. Under a product supply agreement we signed with Lucent in
        October 1998 after extensive qualifying and testing of our AirStar
        product, Lucent will sell and market our AirStar equipment on a
        non-exclusive basis for a period of up to three years, with an option to
        extend this initial period. Lucent is currently marketing the AirStar
        product under the name Lucent OnDemand. We have agreed to manufacture
        and sell our products to Lucent and to provide Lucent with technical
        support and assistance in the development of customer proposals. Lucent
        offers the OnDemand solution as part of an end-to-end solution with a
        complete suite of support services, NetCare(R), that includes planning,
        design and consulting, network implementation and integration and
        administration services and tools as well as comprehensive support.

      - Siemens. Under a product supply agreement we entered into with Siemens
        in January 1998, Siemens and some of its affiliates will sell and market
        our products on a non-exclusive basis for a period of up to five years
        and we will manufacture and sell these products. Siemens is currently
        marketing the AirStar product under the name Siemens SRA MP. Siemens
        sells our products as part of an integrated network solution and is a
        shareholder of Netro.

      We are selectively considering alliance opportunities with additional
system integrators.

CUSTOMERS

        We target service providers worldwide that have rights to wireless
spectrum suitable for high-speed services or are planning to acquire rights to
deliver high-speed services to subscribers. We began shipping the trial AirStar
system to service providers in the third quarter of 1998. Our direct sales in
most cases are to our system integrators, Lucent and Siemens, or to distributors
that in turn sell to service providers. The AirStar system is currently deployed
in 44 trials, 8 of which are commercial pilots. These trials and commercial
pilots are being conducted by 32 service providers, system integrators and
enterprises in 24 countries worldwide. The following is a partial list of
service providers or enterprises that have purchased or deployed our AirStar
system, either as a trial system or to carry traffic to subscribers, and the
locations of their deployments. In each case, we have recognized revenues in
excess of $90,000.

</TABLE>

        We also have trials with service providers in the U.S., Germany and
Japan and system integrators in the U.S. and Europe. During 1997, 1998 and 1999,
our five largest customers accounted for more than 50% of our revenues. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".

OPERATIONS AND MANUFACTURING

      Our manufacturing activities, based in our San Jose facility, consist
primarily of pilot manufacturing, final testing and system staging. Our strategy
is to outsource manufacturing to contract manufacturers, which have the
expertise and ability to achieve cost reductions associated with volume
manufacturing and to respond quickly to customer orders while maintaining high
quality standards. This also serves to turn some of our fixed costs into
variable costs and enables us to enjoy the purchasing efficiencies of these
larger manufacturers. We have manufacturing contracts in place with Solectron
California Corporation, Microelectronic Technology Inc. of Taiwan and NEC
America. Microelectronic Technology Inc. manufactures millimeter wave radio
equipment, Solectron manufactures both millimeter wave radio equipment digital

new contract manufacturers to expand our manufacturing capacity and better
control manufacturing costs.

      Our operations and manufacturing groups facilitate technology transfer
between our research and development group and the contract manufacturers. We
may also use our manufacturing operation to expedite the sales cycle before the
full product release to external manufacturers.

RESEARCH AND DEVELOPMENT

      We believe that our extensive experience designing and implementing
high-quality network and radio components and system software has enabled us to
develop high-value integrated systems solutions. As a result of these
development efforts, we believe we have created an industry-leading platform for
cost-effective high-speed wireless voice and data delivery with dynamic
allocation of capacity.

      We believe that our future success depends on our continued investment in
research and development in core radio, networking and software technologies,
and we expect to continue to invest a significant portion of revenues in this
area. Our research and development expenses for 1999, 1998 and 1997 were $19.3
million, $16.1 million and $15.3 million. We are committed to an ongoing new
product development program that is based on an assessment of service providers'
needs and technological changes in the communications market. We are currently
investing significant resources in enhancing our network management software,
integrating base station components, extending the capabilities, frequencies and
capacity of AirStar's transmission, improving performance and accelerating cost
reduction.

CUSTOMER ADVOCACY

      A high level of continuing service and support is critical to our
objective of developing long-term customer relationships. We have recently
merged our customer support functions with our quality assurance group to
consolidate all respects of our customer service, satisfaction and
quality assurance initiatives into a customer advocacy group. Our customer
advocacy organization is based in our San Jose headquarters. We also have a
customer support presence in Germany and the United Kingdom. Our customer
advocacy organization in San Jose serves as the interface to our research and
development group to highlight certain problems and also provides information
about customers' needs to the marketing and research and development
organizations. Our customer support model consists of three tiers of support:

        - local problem isolation, which provides for on-site problem
          identification and resolution of relatively simple issues;

        - fault isolation and repair, which provides for consultation and
          instruction by technicians trained by product experts; and

        - expert level support from product engineering experts for the
          resolution of problems not remedied by the first two levels of
          support.

      Our main focus is to provide system integrators with the ability to
provide local support worldwide to service providers, including training, spare
parts, maintenance and installation. As most of the hands-on support is provided
through system integrators, local resellers or the service providers themselves,
we focus on offering various training courses to enable system integrators and
service providers to perform both local problem isolation and fault isolation
and repair. When the sale is direct to the service provider, the service
provider typically assumes responsibilities for both local problem isolation and
fault isolation and repair tiers. Currently, the majority of our service and
support activities are related to training and installation support for service
providers. These services are provided directly at customer installations by our
customer advocacy group or remotely by our San Jose headquarters team.

      We have a number of flexible hardware and software maintenance and
customer support programs available for products beyond the applicable warranty
period, depending on our

                                       8
<PAGE>   9

customer preferences. In the case of trials, we offer an evaluation support
package, where training, installation and acceptance testing are delivered
within specific time frames. These activities are usually performed on-site by
our personnel. As more trials begin carrying commercial traffic, we will migrate
the support capabilities to off-hours, 24-hour, 7-day support, and continue to
provide expert level support for service providers and system integrators.

COMPETITION


      The market for high-speed, wireless, point-to-multipoint
telecommunications equipment is rapidly evolving and highly competitive.
Increased competition is likely to result in price reductions, shorter product
life cycles, reduced gross margins, longer sales cycles and loss of market
share, any of which would adversely affect our business. As a provider of
high-speed wireless telecommunications equipment, we compete with a number of
large telecommunications equipment suppliers including Alcatel, Ericsson,
Hughes, Marconi, Newbridge, Nortel and Spectrapoint, a joint venture between
Cisco and Motorola, as well as with smaller start-up companies. In addition,
well capitalized companies such as Nokia are potential entrants into the market.
As a technology for providing high-speed telecommunications services, high-speed
wireless solutions compete with other high-speed wire-based solutions, such as
digital subscriber lines, fiber optic cable, cable modems and high-speed wires
leased from traditional telecommunications service providers and satellite
technologies.

      We expect competition to persist and intensify in the future. Many of our
competitors are substantially larger than we are and have significantly greater
financial, sales and marketing, technical, manufacturing and other resources and
more established distribution channels. These competitors may be able to respond
more rapidly to new or emerging technologies and changes in customer
requirements or to devote greater resources to the development, promotion, sale
and financing of their products than we can. Our competitors may also attempt to
influence the adoption of standards that are not compatible with our current
architecture. Our larger, more established competitors may have more influence
with standards setting bodies than we do. In addition, if standards other than
ours are adopted, this may require us to incur additional development and
integration costs and may delay our sales efforts.

      Some of our competitors may make strategic acquisitions or establish
cooperative relationships among themselves or with third parties to increase
their ability to gain customer market share rapidly. These competitors may enter
our existing or future markets with solutions that may be less expensive,
provide higher performance or additional features or be introduced earlier than
our solutions. We also expect that other companies may enter our market with
better products and technologies. If any technology that is competing with ours
is more reliable, faster or less expensive or has other advantages over our
technology, then the demand for our products and services would decrease, which
would seriously harm our business.

      We expect our competitors to continue to improve the performance of their
current products and to introduce new products or new technologies that may
supplant or provide lower cost alternatives to our products. To be competitive,
we must continue to invest significant resources in research and development,
sales and marketing and customer support. We cannot be sure that we will have
sufficient resources to make these investments or that we will be able to make
the technological advances necessary to be competitive. As a result, we may not
be able to compete effectively against our competitors.

INTELLECTUAL PROPERTY

      We rely on a combination of patent, copyright, trademark and trade secret
laws, as well as confidentiality agreements and licensing arrangements, to
establish and protect our proprietary rights. We presently have two issued U.S.
patents, and two patent applications pending, with more in process. AirView,
AirMAN and AirStar are our registered trademarks. CellMAC, Netro and the Netro
logo are our trademarks. Every other trademark, trade name or service mark
appearing in this prospectus belongs to its holder.

                                       9
<PAGE>   10

      Despite our efforts to protect our proprietary rights, existing copyright,
trademark and trade secret laws afford only limited protection. In addition, the
laws of some foreign countries do not protect our proprietary rights to the same
extent as do the laws of the United States. Attempts may be made to copy or
reverse engineer aspects of our products or to obtain and use information that
we regard as proprietary. Accordingly, we may not be able to protect our
proprietary rights against unauthorized third-party copying or use. Furthermore,
policing the unauthorized use of our products is difficult. Litigation may be
necessary in the future to enforce our intellectual property rights, to protect
our trade secrets or to determine the validity and scope of the proprietary
rights of others. This litigation could result in substantial costs and
diversion of resources and could have a material adverse effect on our future
operating results.

<S>                                      <C>               <C>
 Third Quarter (ended 9/30/99)              $42.13            $19.13
 Fourth Quarter (ended 12/31/99)            $51.00            $22.13
</TABLE>


           The Closing price of the Company's Common Stock on The Nasdaq Stock
        Market on March 24, 2000 was $83.00.

           Future stock prices may be subject to volatility, particularly on a
quarterly basis. Any shortfall in revenues or net income from amounts expected
by securities analysts could have an immediate and significant adverse effect on
the trading price of the Company's stock.

(b)        Holders

           The Company's Common Stock is traded on the Stock Market under the

                                       10

symbol NTRO. As of March 24, 2000, the Company had approximately 294
shareholders of record.

(c)        Dividends

           The Company has not paid dividends on its Common Stock at any time
and has no present plans to do so in the future.

(d)        Report of offering securities and use of proceeds therefrom

            On August 18, 1999, in connection with the Company's initial public
offering, a Registration Statement on Form S-1 (No. 333-81325) was declared
effective by the Securities and Exchange Commission, pursuant to which 5,750,000
shares of the Company's Common Stock were offered and sold for the account of
the Company at a price of $8.00 per share, generating gross offering proceeds of
$46.0 million. The managing underwriters were Merrill Lynch, Pierce, Fenner &
Smith Incorporated, BancBoston Robertson Stephens Inc. and Dain Rauscher
Wessels, a division of Dain Rauscher Incorporated.

           The Company incurred the following expenses in connection with the
offering:



<TABLE>
<CAPTION>
<S>                                                   <C>
    Underwriting discounts and commissions            $3,220,000
    Other expenses                                     1,175,000
                                                      ----------
               Total Expenses                         $4,395,000
</TABLE>


           All of such expenses were direct or indirect payments to others.

           The net offering proceeds to the Company after deducting the total
expenses above were approximately $41,605,000. From August 18, 1999 to December
31, 1999, the Company used such net offering proceeds, in direct or indirect
payments to others, as follows:



<TABLE>
<S>                                                                <C>
 Investment in short-term, interest-bearing obligations            $37,887,000
 Working Capital                                                     3,718,000
                                                                   -----------
            Total                                                  $41,605,000
</TABLE>


           Each of such amounts is a reasonable estimate of the application of
the net offering proceeds. This use of proceeds does not represent a material
change in the use of proceeds described in the prospectus of the Registration
Statement.

OVERVIEW

      We are a leading provider of wireless broadband access equipment used by
telecommunications service providers to provide businesses with high-speed
internet access. We were incorporated in 1994 and introduced our first product,
the AirMAN system, in 1996. Recognizing the competitiveness of the market for
AirMAN products, we decided to devote substantially all of our product
development efforts to the AirStar product from 1996 onward. The AirMAN system
was designed to provide a dedicated link to connect two high traffic nodes in a
network. Unlike the AirMAN system, the AirStar system allows multiple
subscribers to communicate with a single base station radio in a
point-to-multipoint architecture using packet based technology. We began initial
sales of an early 26 GHz AirStar system in Europe in early 1998. With the
successful trial shipments of the AirStar system, we discontinued AirMAN in
September 1998. We shipped the first trial AirStar systems for 26 GHz in the
third quarter of 1998. We then shipped a trial version of a 10 GHz AirStar
product in November 1998. Based on our success in field trials and the receipt
of limited quantities of AirStar subsystems from our contract manufacturers, we
made the 26 GHz AirStar product commercially available in January 1999 and the
10 GHz AirStar product commercially available in October 1999. However, the
products were, and continue to be, available only in limited quantities due to
manufacturing and capacity constraints. Additionally, we shipped a trial version
of a 38 GHz product in September 1999. We also expect to begin customer testing
of a preliminary version of a 28 GHz AirStar product in the first quarter of
2000.

      All of our 1997 revenues, approximately 47% of our 1998 revenues and 2% of
our 1999 revenues were derived from sales of the AirMAN system. Due to the
product transition, revenues declined slightly to $5.4 million in 1998 from $5.6
million in 1997. We had negative gross margins in each quarter of 1997 and 1998
as a result of declining average selling prices in the market for the AirMAN
system; however, our 1999 gross margins were positive due primarily to the
advent of AirStar product sales.

      Currently, all of our revenues are generated from sales of AirStar systems
through system integrators, local resellers and our direct sales force. In the
first quarter of 1998, we entered into a product supply agreement with Siemens.
In the third quarter of 1998, we signed a product supply and joint development
agreement with Lucent. For 1998 and 1999, international revenues represented
approximately 76% and 43% of total revenues. In addition, substantially all of
our domestic revenues are derived from systems intended for installation in
international locations.

      Sales to our four largest customers represented approximately 77% of our
total revenue

                                       13
<PAGE>   14

in 1999, 68% of our total revenue in 1998 and 92% of our total revenue in 1997.
We expect that our key customers will continue to account for a significant
portion of our total revenue for 2000 and in the future.

      Although we have historically assembled our products in-house, we are
currently in the process of outsourcing manufacturing and assembly to contract
manufacturers. Solectron began providing us with AirStar subsystems in the first
quarter of 1999. In January 1999, we also signed a manufacturing agreement with
Microelectronic Technology Inc. of Taiwan, to obtain a second source for the
AirStar radios and to increase our manufacturing capacity. In August 1999, we
received our first AirStar subsystems from this manufacturer. We expect these
contract manufacturers to be responsible for most of our volume production in
the future. In January 2000, we signed a manufacturing agreement with NEC
America to obtain a second source for AirStar digital system components. In
December 1999, we received and qualified initial subsystems from this
manufacturer.

      System integrators and service providers typically perform numerous tests
and extensively evaluate products before incorporating them into networks. The
time required for testing, evaluation and design of our products into the
service provider's network typically ranges from six to twelve months. If a
service provider decides to supply commercial service with our products, it can
take an additional six to twelve months before a service provider commences
deployment of our products. During the trial period, we sell to service
providers a limited number base stations and corresponding subscriber equipment
The successful completion of this trial phase often results in another sale of
additional hubs and subscriber equipment intended for commercial service.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1998 AND 1999

      REVENUES. Current revenues primarily consist of product revenues from the
sale of the AirStar system. Revenues increased from $5.4 million in 1998 to
$18.2 million in 1999, due principally to increased AirStar system sales, which
were slightly offset by the final phase-out of AirMAN sales. Substantially all
of the revenues for these years were generated from installations in
international locations. Sales to major customers were as follows:

* Sales less than 10%.

      GROSS PROFIT (LOSS). Gross profit represents total revenue less the cost
revenue. Cost of revenues consists of contract manufacturing costs, material
costs, compensation costs, manufacturing overhead, warranty reserves and other
direct product costs. Gross profit increased from a loss of $4.2 million in 1998
to a profit of $3.3 million in 1999, principally due to increased AirStar system
sales, which typically have a higher margin than predecessor products.

      RESEARCH AND DEVELOPMENT. Research and development expenses consist of
compensation costs, the cost of some software development tools, consultant fees
and prototype expenses

                                       14
<PAGE>   15

related to the design, development and testing of our products. Research and
development expenses increased from $16.1 million in 1998 to $19.3 million in
1999, primarily due to increases in personnel and related compensation costs,
prototype material expenses, third-party engineering charges and expenses
related to the release of new product features for the AirStar system. Gross
research and development expenses increased from $17.0 million in 1998 to $19.9
million in 1999. We expect that continued substantial investment in research and
development will be critical to attaining our strategic product and cost
reduction objectives.

      SALES AND MARKETING. Sales and marketing expenses consist primarily of
compensation costs, commissions, travel and related expenses for marketing,
sales, customer advocacy and field service support personnel, as well as product
management, trade show and promotional expenses. Sales and marketing expenses
increased from $4.8 million in 1998 to $5.8 million in 1999. The increase was
primarily due to the significant expansion in sales, technical assistance and
field support personnel necessary to support both the pre-sale and post-sale
activities associated with the AirStar system. We expect these expenses to
continue to increase on an absolute basis as we invest in expanding our sales
and customer advocacy organizations.

      GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of compensation costs and related expenses for executive, finance,
management information systems, human resources and administrative personnel.
These expenses also include professional fees, facilities and other general
corporate expenses. General and administrative expenses increased from $4.0
million in 1998 to $7.4 million in 1999. The increase was primarily due to
deferred compensation charges, increased rent and overhead expenses associated
with additional facilities, as well as the increased cost associated with being
a public company. We expect that the growth of our operations as a public
company will continue to require additional personnel and costs.

      AMORTIZATION OF DEFERRED STOCK COMPENSATION. Amortization of deferred
stock compensation results from the granting of stock options to employees with
exercise prices per share determined to be below the estimated fair values per
share of our common stock at dates of grant. The deferred compensation that
results is being amortized to expense over the vesting periods of the individual
options, generally four years. We have recorded total deferred stock
compensation of $4.8 million through December 31, 1999.

      OTHER INCOME, NET. Other income (expense), net consists primarily of
interest income earned on low-risk, short-term investments and interest paid on
outstanding debt. Other income, net increased from $304,000 in 1998 to $353,000
in 1999 primarily due to higher interest income from higher average cash
balances partially offset by increased interest expense resulting from greater
utilization of secured equipment loans and lease and bank financing for working
capital.

      NET LOSS. Net loss was relatively constant at $28.8 million from 1998 to
1999 principally due to higher gross profit, offset by increased operating
expenses.



YEARS ENDED DECEMBER 31, 1997 AND 1998

      REVENUES. Revenues decreased from $5.6 million in 1997 to $5.4 million in
1998. This decrease was primarily due to the discontinuation of the AirMAN
system, which resulted in declining revenues that more than offset the revenues
generated from the launch of the AirStar system. Substantially all of the
revenues for these years were generated from installations in international
locations. Sales to major customers were as follows:

<PAGE>   16

      GROSS LOSS. Gross loss increased from $2.7 million in 1997 to $4.2 million
in 1998. This increase was primarily due to pricing pressures and increased
warranty reserves for the AirMAN system.

      RESEARCH AND DEVELOPMENT. Research and development expenses increased from
$15.3 million in 1997 to $16.1 million in 1998. The increase was primarily due
to increases in personnel and related compensation costs, prototype material
expenses, third-party engineering charges and expenses related to the trial
release of the initial AirStar system. Gross research and development expenses
increased from $15.3 million in 1997 to $17.0 million in 1998.

      SALES AND MARKETING. Sales and marketing expenses increased from $3.8
million in 1997 to $4.8 million in 1998. The increase was primarily due to the
significant expansion in sales, technical assistance and field support personnel
necessary to support both the pre-sale and post-sale activities associated with
the AirStar system.

      GENERAL AND ADMINISTRATIVE. General and administrative expenses increased
from $3.5 million in 1997 to $4.0 million in 1998. The increase was primarily
due to increased rent expense due to relocation to larger facilities, as well as
an increase in personnel from 8 to 15.

      OTHER INCOME, NET. Other income, net decreased from $703,000 in 1997 to
$304,000 in 1998, primarily due to greater utilization of secured equipment
loans and lease and bank financing for working capital.

      NET LOSS. Net loss increased from $24.5 million in 1997 to $28.8 million
in 1998 primarily due to increases in operating expenses and negative gross
profit.

LIQUIDITY AND CAPITAL RESOURCES

      As of December 31, 1999, cash and cash equivalents were $7.5 million and
short-term investments were $37.9 million. We have a $6.0 million bank line of
credit. As of December 31, 1999, borrowings outstanding were $4.3 million and
amounts utilized for outstanding letters of credit were $300,000 under this
agreement. The line of credit is secured by eligible outstanding accounts
receivable and inventory. The borrowings under the line are due in January 2001
and accrue interest at the 30-day LIBOR plus 2.25% or the bank's prime rate, at
our option. In addition, we have secured equipment financing which allows a
maximum borrowing of $3.0 million of which $1.1 million was available as of
December 31, 1999. See note 6 of notes to consolidated financial statements.

      Cash used in operating activities was $25.9 million for the year ended
December 31, 1998 and $29.1 million for the same period in 1999. Cash used for
operations for both periods was primarily due to the net loss, partially offset
by non-cash charges.

      Cash used in investing activities was $2.2 million for the year ended
December 31, 1998, primarily due to excess cash invested in short-term
investments and capital equipment purchases. Cash used in investing activities
was $30.6 million for the year ended December 31, 1999, primarily due to excess
cash invested in short-term investments.

      Cash provided by financing activities was $18.5 million and $61.0 million
for the years ended December 31, 1998 and 1999, respectively. Cash provided by
financing activities for both periods was primarily due to issuances of stock
and, to a lesser extent, capital lease and bank financing. Cash provided by
financing activities in 1999 includes net

                                       16
<PAGE>   17

proceeds of $41.6 million related to our initial public offering in August 1999.

      We completed our initial public offering of common stock in August 1999.
We sold 5,750,000 shares at a price of $8.00 per share. We received net
aggregate proceeds from the initial public offering of $41.6 million, net of
underwriting discounts and commissions and offering costs.

     In March 2000 the Company completed a follow-on public offering. Of the 6
million shares of common stock offered , the Company sold 4,504,111 shares and
selling shareholders sold 1,495,889, at a price of $82.5 per share. We received
net aggregate proceeds of approximately $352.3 million after deducting
underwriting discounts and commission and estimated offering costs.

      We have no material commitments other than obligations under our credit
facilities and operating and capital leases. See notes 6 and 7 of notes to
consolidated financial statements. Our future capital requirements will depend
upon many factors, including the timing of research and product development
efforts and expansion of our marketing efforts. We expect to continue to expend
significant but smaller amounts on property and equipment related to the
expansion of our facilities, and on research and development laboratory and test
equipment.

     The capital required for volume manufacturing is being committed by our
contract manufacturers. We provide six or twelve month forecasts to our contract
manufacturers. We generally commit to purchase products to be delivered within
the most recent 60 days covered by these forecasts with cancellation fees. As of
December 31, 1999, we had committed to make purchases totaling $4.6 million from
these manufacturers in the next 60 days. In addition, in specific instances we
may agree to assume liability for limited quantities of specialized components
with lead times beyond this 60-day period.

      In future periods, we generally anticipate significant increases in our
working capital needs on a period-to-period basis primarily as a result of
planned increased product revenues. In conjunction with the expected increases
in revenues, we expect higher levels of inventory and trade accounts receivable.
While we also expect an increase in trade accounts payable and other
liabilities, we do not expect that they will offset the increases in inventory
and trade accounts receivable.

      We believe that our current cash and cash equivalents balances, short-term
investments and funds available under our existing line of credit will be
sufficient to satisfy our cash requirements for at least the next twelve months.
Our management intends to invest our cash in excess of current operating
requirements in short-term, interest-bearing, investment-grade securities.

YEAR 2000 IMPACT

      We have not experienced any problems with our computer systems relating to
their inability to recognize appropriate dates related to the year 2000. We are
also not aware of any material problems with our clients or vendors.
Accordingly, we do not anticipate incurring material expenses or experiencing
any material operational disruptions as a result of any Year 2000 issues.

RISK FACTORS

      In addition to the other information in this Report, the following
factors should be considered carefully in evaluating the Company's business and
prospects:

WE HAVE A HISTORY OF LOSSES, EXPECT FUTURE LOSSES AND MAY NEVER ACHIEVE
PROFITABILITY

      As of December 31, 1999, we had an accumulated deficit of $96.4 million,
and we expect to continue to incur net losses. We anticipate continuing to incur
significant sales and marketing, research and development and general and
administrative expenses and, as a

                                       17
<PAGE>   18

result, we will need to generate significantly higher revenues to achieve and
sustain profitability. Our financial results prior to 1999 were largely based on
sales of AirMAN, a predecessor product, which we discontinued in September 1998.
For 1999, our financial results were largely based on customer trials and
commercial pilots of our AirStar product line. Although our AirStar revenues
have grown in recent quarters, our past results should not be relied on as
indications of future performance. We cannot be certain that we will realize
sufficient revenues to achieve and sustain profitability. We incurred net losses
of approximately $24.5 million, $28.8 million and $28.8 million in 1997, 1998
and 1999.

WE HAVE NOT MANUFACTURED OUR PRODUCTS IN SUBSTANTIAL VOLUMES. IF WE ARE UNABLE
TO DO SO IN A COST-EFFICIENT WAY, OUR BUSINESS WILL BE ADVERSELY AFFECTED

      Our products are commercially available only in limited quantities. We
began low-volume manufacturing runs in January 1999 with our first contract
manufacturer and in August 1999 with our second contract manufacturer. We are
currently in the process of initiating manufacturing runs with a third contract
manufacturer. If we or our manufacturers are unable to develop processes by
which we can manufacture substantial volumes of our products at the required
quality and expected costs in relatively short periods of time, our financial
results will suffer. Manufacturing our products, particularly the radio elements
of our products, is complex and difficult. One of our contract manufacturers
does not have a history of producing radio elements on a large scale. In
addition, many of our contracts with distributors and system integrators provide
for financial penalties in the event of a delay in delivery of products.

DUE TO OUR LIMITED OPERATING HISTORY IT IS DIFFICULT TO PREDICT FUTURE OPERATING
RESULTS OR OUR STOCK PRICE

      We have generated only limited revenues to date, and revenues from our
current AirStar product have been significant only in the past year. Prior to
1999, most of our revenues came from sales of a discontinued product line. Due
to our limited operating history with our current product line, it is difficult
for us to predict future results of operations. Investors in our common stock
must consider our business and prospects in light of our historical dependence
on a discontinued product line.

IF WE CANNOT REDUCE OUR PRODUCT COSTS, POTENTIAL CUSTOMERS WILL NOT PURCHASE OUR
PRODUCTS AND OUR RESULTS OF OPERATIONS WILL SUFFER

      Market acceptance of our products will depend in part on reductions in the
unit cost of our products. If we cannot reduce the cost of our products, our
product sales, and consequently our results of operations, will suffer. If
prices for alternative high-speed telecommunications services continue to
decline, we may not become profitable. We believe that the price for high-speed
wireless telecommunications equipment is driven by the prevailing price for
other high-speed connection technologies, especially the cost of leasing a
high-speed wire from the traditional telecommunications service provider in a
given locale. Recently, the price of these leased connections has declined
significantly in many countries. In addition, if this trend continues, service
providers might be more likely to use this kind of leased connection than to
introduce new technology such as our products, which would adversely affect our
market share and pricing. Our cost reduction efforts may not allow us to keep
pace with competitive pricing pressures or may not lead to improved gross
margins.

OUR FUTURE OPERATING RESULTS ARE DEPENDENT ON THE SALES OF A SINGLE PRODUCT
LINE. IF THERE ARE UNEXPECTED CHANGES IN REVENUES FROM THIS PRODUCT, WE WILL NOT
HAVE OTHER PRODUCTS TO OFFSET THE NEGATIVE IMPACT ON OUR OPERATING RESULTS

      We currently derive substantially all of our revenues from our AirStar
product line and expect that this will continue for the foreseeable future. If
there are unexpected changes in revenues from this product, we will not have
other products to offset the negative impact on our operating results. Many of
the risk factors listed in this section could negatively affect sales of our
product line.

OUR BUSINESS IS SUBJECT TO MANY FACTORS THAT COULD CAUSE OUR QUARTERLY OPERATING
RESULTS TO FLUCTUATE AND OUR STOCK PRICE TO BE VOLATILE

                                       18
<PAGE>   19

      Our quarterly and annual operating results have fluctuated in the past and
are likely to fluctuate significantly in the future due to the risk factors
described in this section. It is likely that in some future quarter our
operating results will fall below the expectations of securities analysts and
investors. In this event, the market price of our common stock could
significantly decline.

IF WE ARE UNABLE TO DEPLOY OUR PRODUCTS ON A LARGE SCALE OR INTEGRATE THEM INTO
A LARGE-SCALE NETWORK ENVIRONMENT, WE COULD LOSE SALES OPPORTUNITIES, SUFFER
INJURY TO OUR REPUTATION, OR EXPERIENCE WARRANTY CLAIMS

      To date, we have launched our products only in customer trials and
commercial pilots. If our products fail, or do not function adequately, in a
large-scale deployment or in a network environment, we could experience:

        -  delays in or losses of sales opportunities;

        -  diversion of development resources;

        -  injury to our reputation; and

        -  increased service, warranty and replacement costs.

      In addition, our products may contain undetected or unresolved errors when
they are first introduced or as a result of changes we make to reduce
manufacturing costs. Our products are integrated with other network elements.
There may be incompatibilities between these elements and our products that
adversely affect the service provider or its subscribers.

WE DEPEND ON TWO CONTRACT MANUFACTURERS AND WE ARE IN THE PROCESS OF INITIATING
MANUFACTURING RUNS WITH A THIRD. IF THESE MANUFACTURERS ARE UNABLE TO FILL OUR
ORDERS ON A TIMELY BASIS, AND WE ARE UNABLE TO FIND ALTERNATIVE SOURCES, WE MAY
BE UNABLE TO DELIVER PRODUCTS TO MEET CUSTOMER ORDERS

      We currently have relationships with three contract manufacturers of our
products. Two of these provided products to us in 1999, and we expect the third
will begin to provide products to us in the first quarter of 2000. We only
manufacture pilot runs of our products and perform testing and staging at our
own facilities. If our manufacturers are unable or unwilling to continue
manufacturing our products in required volumes, we would have to identify and
train acceptable alternative manufacturers, which could take as long as six
months and cause our results of operations to suffer.

      Our experience with these manufacturers provides us with no basis to
project their delivery schedules, yields or costs. In addition, few
manufacturers produce radios like ours on a large scale. It is possible that a
source may not be available to us when needed, and we may not be able to satisfy
our production requirements at acceptable prices and on a timely basis, if at
all. Any significant interruption in supply would affect the allocation of
products to customers, which in turn could have an adverse effect on our
business.

BECAUSE SOME OF OUR KEY COMPONENTS ARE FROM SOLE SOURCE SUPPLIERS OR REQUIRE
LONG LEAD TIMES, OUR BUSINESS IS SUBJECT TO UNEXPECTED INTERRUPTIONS, WHICH
COULD CAUSE OUR OPERATING RESULTS TO SUFFER

      Many of our key components have long lead times, are purchased from sole
source vendors for which alternative sources are not currently available, and
are complex to manufacture. In the event of a reduction or interruption of
supply, or a degradation in quality, as many as six months could be required
before we would begin receiving adequate supplies from alternative suppliers, if
any. As a result, product shipments could be delayed and our revenues and
results of operations would suffer.

      For example, we purchase our base station shelf from Cisco Systems, Inc.
under an agreement that terminates in September 2000. Cisco has recently
acquired interests in companies with high-speed wireless technology, and we
cannot be certain that Cisco will continue to supply us after the termination of
the current agreement. In addition, we purchase most of our electronic boards
for base station equipment from Solectron, one of our

                                       19
<PAGE>   20

contract manufacturers, and other components from other sole source and long
lead time vendors.

IF WE DO NOT DEVELOP NEW PRODUCTS AND PRODUCT FEATURES IN RESPONSE TO CUSTOMER
REQUIREMENTS OR IN A TIMELY WAY, CUSTOMERS WILL NOT BUY OUR PRODUCTS

      Our inability to develop new products or product features on a timely
basis, or the failure of new products or product features to achieve market
acceptance, could adversely affect our business. We may experience design or
manufacturing difficulties that could delay or prevent our development,
introduction or marketing of new products and enhancements, any of which could
cause us to incur unexpected expenses or lose revenues. For example, the first
trial shipments of AirStar were delayed for almost one year due to technical
problems. In addition, some of our customers have conditioned their future
purchases of our products on the addition of product features. In the past we
have experienced delays in introducing new features. For example, we intended to
introduce base radio units that supported smaller sectors and a new release of
our network management software in 1999, but the release of both of these
features has been delayed until later in 2000. Furthermore, in order to compete
in many markets, we will have to develop different versions of our existing
products that operate at different frequencies and comply with diverse, new or
varying governmental regulations in each market.

WE DEPEND ON TWO SYSTEM INTEGRATORS FOR MOST OF OUR REVENUES. IF THESE SYSTEM
INTEGRATORS DO NOT PROMOTE OR PURCHASE OUR PRODUCTS, OUR BUSINESS WILL BE
ADVERSELY AFFECTED

      We sell most of our products through two system integrators, Lucent and
Siemens. The loss of either of these system integrators or the delay of
significant orders from these system integrators, even if only temporary, could,
among other things:

        -  reduce or delay our revenues;

        -  harm our reputation in the industry; or

        -  reduce our ability to predict our cash flow accurately.

      Aggregate sales through these two system integrators accounted for
approximately 31% and 64% of our revenues for 1998 and 1999, respectively.
Accordingly, unless and until we diversify and expand our customer base, our
future success will significantly depend on the timing and size of future
purchase orders, if any, from these two system integrators. There are a limited
number of system integrators that have the financial resources or technical
expertise to sell, or to integrate, our products globally. If one or both of our
system integrators will not sell, service or integrate our products, and we
cannot identify other system integrators as replacements, we would be limited in
our ability to sell our products.

      Our relationships with our system integrators are non-exclusive and do not
contain minimum purchase commitments. Should either of our system integrators
cease to emphasize systems that include our products, choose to emphasize
alternative technologies or promote products of our competitors, our revenues
and consequently results of operations would be adversely affected. For example,
Siemens has an equity interest in, and a commercial relationship with, one of
our competitors, which may motivate Siemens to select this competitor's
solutions over our own in the future.

IF WE ARE UNSUCCESSFUL IN ESTABLISHING LARGER DIRECT SALES AND CUSTOMER ADVOCACY
ORGANIZATIONS, WE MAY NOT BE ABLE TO GROW OUR BUSINESS

      We intend to grow our direct sales force and customer advocacy
organization. We believe that the efforts of our direct sales force and customer
advocacy organization are important in enabling both ourselves and our system
integrators to acquire customers. We believe that qualified personnel are
difficult to find and, once found, take substantial lead time to become
productive. To the extent that we are unable to expand our direct sales force
and customer advocacy organization, we may be unable to grow our business.


IF HIGH-SPEED WIRELESS TELECOMMUNICATIONS TECHNOLOGY OR OUR IMPLEMENTATION OF
THIS TECHNOLOGY IS NOT ACCEPTED BY SERVICE PROVIDERS, WE WILL NOT BE ABLE TO
SUSTAIN OR GROW OUR BUSINESS


                                       20
<PAGE>   21

      Our future success is substantially dependent on whether high-speed
wireless telecommunications equipment gains market acceptance as a means to
provide telecommunications voice and data services. All of our products are
based on this technology. In the event that service providers adopt technologies
other than the high-speed wireless technology that we offer, we may not be able
to sustain or grow our business. Service providers continuously evaluate
alternative high-speed access technologies, including wire-based technologies
such as digital subscriber lines, cable modems, fiber optic cable and high-speed
wires leased from the traditional service providers in a given locale, as well
as different wireless technologies. In addition, widespread acceptance of our
technology may be hindered by inherent technological limitations, such as a need
for a clear line-of-sight for transmissions and a reduction in coverage radius
in areas that experience heavy rain.


THE MAJORITY OF SERVICE PROVIDERS USING OUR PRODUCTS ARE EMERGING COMPANIES WITH
UNPROVEN BUSINESS MODELS. IF THESE SERVICE PROVIDERS DO NOT SUCCEED, THERE WILL
BE NO MARKET FOR OUR PRODUCTS

      Most telecommunications service providers using our products are emerging
companies with unproven business models. If these new service providers do not
succeed, there will be no market for our products. Neither they nor we have
experience in integrating a complete telecommunications network that includes
our products. The inability of emerging service providers to acquire and keep
customers, acquire radio frequency licenses, successfully raise needed funds or
respond to any trends such as price reductions for their services or diminished
demand for telecommunications services generally, could cause them to reduce
their capital spending on network buildouts. If service providers defer or
curtail their capital spending programs, sales of our products might be
impacted, which would have an adverse effect on our business.

WE HAVE A LONG SALES CYCLE, WHICH COULD CAUSE OUR RESULTS OF OPERATIONS AND
STOCK PRICE TO FLUCTUATE

      We believe our sales cycles are long and unpredictable. As a result, our
revenues may fluctuate from quarter to quarter and fail to correspond with our
expenses. This would cause our operating results and stock price to fluctuate.
System integrators and service providers typically perform numerous tests and
extensively evaluate products before incorporating them into networks. The time
required for testing, evaluation and design of our products into the service
provider's network typically ranges from six to twelve months. If a service
provider decides to supply commercial service with our products, it can take an
additional six to twelve months before a service provider commences deployment
of our products. Some additional factors that affect the length of our sales
cycle include:

        -  testing and evaluation;

        -  acquisition of roof rights;

        -  deployment and planning of network infrastructure;

        -  complexity of a given network;

        -  scope of a given project;

        -  availability of radio frequency; and

        -  regulatory issues.

      In addition, the delays inherent in our sales cycle raise additional risks
of service provider decisions to cancel or change their product plans. Our
business could be adversely affected if a significant customer reduces or delays
orders during our sales cycle or chooses not to deploy networks incorporating
our products.

INTENSE COMPETITION IN THE MARKET FOR COMMUNICATIONS EQUIPMENT COULD PREVENT US
FROM INCREASING OR SUSTAINING REVENUES OR ACHIEVING OR SUSTAINING PROFITABILITY

      The market for high-speed, wireless, point-to-multipoint
telecommunications equipment is rapidly evolving and highly competitive.
Increased competition is likely to result in price reductions, shorter
product life cycles, reduced gross margins, longer sales cycles and

                                       21
<PAGE>   22

loss of market share, any of which would adversely affect our business. As a
provider of high-speed wireless telecommunications equipment, we compete with a
number of large telecommunications equipment suppliers, including Alcatel,
Ericsson, Hughes, Marconi, Newbridge, Nortel and Spectrapoint, a joint venture
between Cisco and Motorola, as well as with smaller start-up companies. In
addition, well capitalized companies such as Nokia are potential entrants into
the market. As a technology for providing high-speed telecommunications
services, high-speed, wireless solutions compete with other high-speed,
wire-based solutions, such as digital subscriber lines, fiber optic cable, cable
modems and high-speed wires leased from traditional telecommunications service
providers and satellite technologies.

      We expect our competitors to continue to improve the performance of their
current products and to introduce new products or new technologies that may
supplant or provide lower cost alternatives to our products. Our competitors may
also attempt to influence the adoption of standards that are not compatible with
our current architecture. Our larger, more established competitors may have more
influence with standards setting bodies than we do. In addition, if standards
other than ours are adopted, this may require us to incur additional development
and integration costs and may delay our sales efforts. To be competitive, we
must continue to invest significant resources in research and development, sales
and marketing and customer support. We cannot be sure that we will have
sufficient resources to make these investments or that we will be able to make
the technological advances necessary to be competitive. As a result, we may not
be able to compete effectively against our competitors.

BECAUSE WE MUST SELL OUR PRODUCTS IN MANY COUNTRIES THAT HAVE DIFFERENT
REGULATORY SCHEMES, IF WE CANNOT DEVELOP PRODUCTS THAT WORK WITH DIFFERENT
STANDARDS, WE WILL BE UNABLE TO SELL OUR PRODUCTS

      If our sales are to grow, we must sell our products in many different
countries. Many countries require communications equipment used in their country
to comply with unique regulations, including safety regulations, radio frequency
allocation schemes and standards. If we cannot develop products that work with
different standards, we will be unable to sell our products. If compliance
proves to be more expensive or time consuming than we anticipate, our business
would be adversely affected. Some countries have not completed their radio
frequency allocation process and therefore we do not know the standards with
which we would be forced to comply. We have not completed all activities
necessary to comply with existing regulations and requirements in most of the
countries in which we intend to sell our products. Furthermore, standards and
regulatory requirements are subject to change. For example, standards for
antenna design expected to be established by the European Telecommunications
Standards Institute are currently in flux.

IF WE ARE UNABLE TO MANAGE OUR INTERNATIONAL OPERATIONS EFFECTIVELY, OUR
BUSINESS WOULD BE ADVERSELY AFFECTED

      Sales in foreign countries accounted for 76% and 43% of our revenues in
1998 and 1999, respectively. In addition, most equipment purchased by domestic
customers has been shipped to international service providers. Our international
operations are subject to a number of risks and uncertainties, including:

        -  the difficulties and costs of obtaining regulatory approvals for
           our products;

        -  unexpected changes in regulatory requirements; and

        -  legal uncertainties regarding liability, tariffs and other trade
           barriers.

      Any of these factors could have an adverse impact on our existing
international operations and business or impair our ability to expand into
international markets.

                                       22
<PAGE>   23

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS. CHANGES IN TIMING AND SIZE OF
THESE CUSTOMERS' ORDERS MAY CAUSE OUR OPERATING RESULTS AND STOCK PRICE TO
FLUCTUATE

      We sell our products to a small number of customers. Unless and until we
diversify and expand our customer base, our future success will significantly
depend on:

        -  the timing and size of future purchase orders, if any, from our
           largest customers;

        -  the product requirements of these customers;

        -  the financial and operational success of these customers; and

        -  the success of service providers that have deployed our products.

      Sales to our largest customers have in the past fluctuated and may in
the future fluctuate significantly from quarter to quarter and year to year.

MANY PROJECTS THAT INCLUDE OUR PRODUCTS REQUIRE SYSTEM INTEGRATION EXPERTISE AND
THIRD-PARTY FINANCING, WHICH WE ARE UNABLE TO PROVIDE. IF SOURCES FOR SYSTEM
INTEGRATION OR FINANCING CANNOT BE OBTAINED AS NEEDED, SERVICE PROVIDERS MAY NOT
SELECT OUR PRODUCTS

      Some service providers using our products purchase them as a part of a
larger network deployment program that can require capital expenditures in the
hundreds of millions of dollars. In some circumstances, these service providers
require their equipment vendors to integrate equipment into these larger
networks and finance deployment. We will be unable to provide this integration
or financing and therefore will have to rely on the ability of our system
integrators or third parties to integrate or finance these transactions. In the
event that we are unable to identify distributors and system integrators that
are able to provide this integration or financing on our behalf, we would be
unable to compete for the business of some service provider accounts and our
business might be adversely affected.

IF WE ARE UNABLE TO HIRE OR RETAIN OUR PERSONNEL, WE MIGHT NOT BE ABLE TO
OPERATE OUR BUSINESS SUCCESSFULLY

      Given our early stage of development, we are dependent on our ability to
attract, retain and motivate high caliber personnel. The loss of the services of
any key personnel or our inability to hire new personnel could restrict our
ability to compete effectively. Competition for qualified personnel in our
industry and in the Silicon Valley is intense, and we may not be successful in
attracting and retaining these personnel. There are only a limited number of
people with the requisite skills, particularly people with millimeter wave radio
expertise. We are also dependent on the continued contributions of our principal
sales, engineering and management personnel, many of whom would be difficult to
replace. We currently do not maintain key person life insurance on any of our
key executives.

CLAIMS THAT WE INFRINGE THIRD-PARTY INTELLECTUAL PROPERTY RIGHTS COULD RESULT IN
SIGNIFICANT EXPENSES OR RESTRICTIONS ON OUR ABILITY TO SELL OUR PRODUCTS IN
PARTICULAR MARKETS


      From time to time, third parties may assert patent, copyright, trademark
and other intellectual property rights to technologies and in various
jurisdictions that are important to our business. Any claims could be
time-consuming, result in costly litigation, divert the efforts of our technical
and management personnel, cause product shipment delays or require us to enter
into royalty or licensing agreements, any of which could have an adverse effect
on our operating results. Royalty or licensing agreements, if required, may not
be available on terms acceptable to us, if at all. In addition, in our sales
agreements, we agree to indemnify our customers for any expenses or liabilities
resulting from claimed infringements of patents, trademarks or copyrights of
third parties.

CONTROL BY OUR EXISTING SHAREHOLDERS COULD DISCOURAGE POTENTIAL ACQUISITIONS OF
OUR BUSINESS THAT OTHER SHAREHOLDERS MAY CONSIDER FAVORABLE


                                       23
<PAGE>   24
        Our executive officers, directors and 5% or greater shareholders and
their affiliates own 16,492,453 shares or approximately 33.5% of the outstanding
shares of common stock. Acting together, these shareholders would be able to
exert substantial influence on matters requiring approval by shareholders,
including the election of directors. This concentration of ownership could have
the effect of delaying or preventing a change in our control or otherwise
discouraging a potential acquirer from attempting to obtain control of us, which
in turn could have an adverse effect on the market price of our common stock or
prevent our shareholders from realizing a premium over the market price for
their shares of common stock.

OUR ARTICLES OF INCORPORATION AND BYLAWS MAY DISCOURAGE POTENTIAL ACQUISITIONS
OF OUR BUSINESS BY THIRD PARTIES THAT SHAREHOLDERS MAY CONSIDER FAVORABLE

      Some provisions of our articles of incorporation and bylaws and of
California law may discourage, delay or prevent a merger or acquisition that
shareholders may consider favorable. This may reduce the market price of our
common stock. A summary of these provisions in our articles and bylaws is
included in "Description of Capital Stock - Anti-Takeover Provisions".

OUR STOCK PRICE MAY BE VOLATILE

      Since our initial public offering in August 1999, our stock price has
experienced significant volatility. We expect that the market price of our
common stock also will fluctuate in the future in response to many of the risk
factors listed in this section. These fluctuations may be exaggerated if the
trading volume of our common stock is low.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      FOREIGN CURRENCY HEDGING INSTRUMENTS. We transact business in various
foreign currencies and, accordingly, we are subject to exposure from adverse
movements in foreign currency exchange rates. To date, the effect of changes in
foreign currency exchange rates on revenues and operating expenses have not been
material. Basically, all of our revenues are earned in U.S. dollars. Operating
expenses incurred by our German subsidiary are denominated primarily in European
currencies. We currently do not use financial instruments to hedge these
operating expenses. We intend to assess the need to utilize financial
instruments to hedge currency exposures on an ongoing basis.

      We do not use derivative financial instruments for speculative trading
purposes.

      FIXED INCOME INVESTMENTS. Our exposure to market risks from changes in
interest rates relates primarily to corporate debt securities. We place our
investments with high credit quality issuers and, by policy, limit the amount of
the credit exposure to any one issuer.

      Our general policy is to limit the risk of principal loss and ensure the
safety of invested funds by limiting market and credit risk. All highly liquid
investments with a maturity of less than three months at the date of purchase
are considered to be cash equivalents; all investments with maturities of three
months or greater are classified as held-to-maturity and considered to be
short-term investments.

                           REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of Netro Corporation:

   We have audited the accompanying consolidated balance sheets of Netro
Corporation (a California corporation) and subsidiaries as of December 31, 1999
and 1998, and the related consolidated statements of operations and
comprehensive loss, shareholders' equity and cash flows for each of the three
years in the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

   We conducted our audits 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 financial statements referred to above present fairly, in
all material respects, the financial position of Netro Corporation and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with generally accepted accounting principles.

                                   NETRO CORPORATION

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    1.  DESCRIPTION OF BUSINESS:

    Netro Corporation (collectively, with its subsidiaries, the "Company") was
    incorporated in California on November 14, 1994. Netro is a leading provider
    of broadband wireless access equipment to competitive communications service
    providers worldwide. Netro's AirStar broadband access system derives its
    price-performance benefits from dynamic bandwidth allocation and a
    point-to-multipoint architecture that provides integrated voice and
    high-speed packet data services. The Company operates in one business
    segment.

    2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

    PRINCIPLES OF CONSOLIDATION

       The consolidated financial statements include the accounts of the
    Company, its wholly-owned subsidiaries in Germany, France and a dormant
    subsidiary in Israel.

    FOREIGN CURRENCY TRANSLATION

       The functional currency of the Company's subsidiaries is the local
    currency. Gains and losses resulting from the translation of the financial
    statements have not been material to date.

       Foreign exchange gains and losses resulting from foreign currency
    transactions were not material in any of the periods presented.

    USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

       The preparation of 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.

    CASH AND CASH EQUIVALENTS

       Cash and cash equivalents consist of short-term, highly liquid
    investments with original maturities of less than three months.

    SHORT-TERM INVESTMENTS

       The Company classifies its investments in debt securities as
    "held-to-maturity." Accordingly, these investments, which mature at various
    dates through February 2000, are valued using the amortized cost method. The
    fair value of the investments approximates amortized cost and, as such, the
    gross unrealized holding gains and losses at December 31, 1999 and 1998,
    were not material.

       The carrying value of the Company's investments by major security type
    consisted of the following (in thousands):

    EQUIPMENT AND LEASEHOLD IMPROVEMENTS

       Equipment is recorded at cost and depreciated using the straight-line
    method based upon the estimated useful lives of the assets, which range from
    three to five years. Leasehold improvements are recorded at cost and are
    amortized over the estimated lives of the improvements or the term of the
    lease, whichever is shorter. Maintenance and repairs that do not improve or
    extend the life of assets are expensed as incurred.

    SOFTWARE DEVELOPMENT COSTS

       Under the criteria set forth in Statement of Financial Accounting
    Standards ("SFAS") No. 86, "Accounting for the Costs of Computer Software to
    be Sold, Leased or Otherwise Marketed," capitalization of software
    development costs begins upon the establishment of technological feasibility
    of the product. The establishment of technological feasibility and the
    ongoing assessment of the recoverability of these costs requires
    considerable judgment by management with respect to certain external
    factors, including, but not limited to, anticipated future gross product
    revenues, estimated economic life and changes in software and hardware
    technology. Amounts that could have been capitalized under this statement
    after consideration of the above factors were immaterial and, therefore, no
    software development costs have been capitalized by the Company to date.

    REVENUE RECOGNITION

       Revenues from product sales are generally recognized when all of the
    following conditions are met: the product has shipped, an arrangement exits
    with the customer and the Company has the right to invoice the customer,
    collection of the receivable is probable and the Company has fulfilled all
    of its material contractual obligations to the customer. Provisions are made
    at the time of revenue recognition for estimated warranty costs.

    RESEARCH AND DEVELOPMENT

       Research and development costs are expensed as incurred and consist
    primarily of payroll costs, other direct expenses and overhead. The Company
    received third-party research and development funding of $625,000 and
    $900,000 in 1999 and 1998, respectively. The Company offset research and
    development expenses with the funding when agreed-upon milestones were met.

    COMPUTATION OF HISTORICAL NET LOSS PER SHARE AND PRO FORMA NET LOSS PER
    SHARE

       Historical net loss per share was calculated under SFAS No. 128,
    "Earnings per Share." Basic and diluted net loss per share on a historical
    basis is computed using the weighted average number of shares of common
    stock outstanding. Potential common shares from the conversion of
    convertible preferred stock and exercise of stock options and warrants are
    excluded from diluted net loss per share because they would be antidilutive.
    The total number of shares excluded from diluted net loss per share relating
    to these securities was 4,408,949, 32,453,093 and 29,777,846 shares for
    1999, 1998 and 1997, respectively.

       Pursuant to Securities and Exchange Commission Staff Accounting Bulletin
    No. 98, convertible preferred stock and common stock issued or granted for
    nominal consideration prior to the anticipated effective date of an initial
    public offering must be included in the calculation of basic and diluted net
    loss per share as if they had been outstanding for all periods presented. To
    date, the Company has not had any issuances or grants for nominal
    consideration.

       Pro forma basic and diluted net loss per share is calculated assuming the
    conversion of convertible preferred stock into an equivalent number of
    shares of common stock, as if the shares had converted on the dates of their
    issuance.

       The following table presents the calculation of historical and pro forma
    net loss per share (in thousands, except per share data):

    COMPREHENSIVE LOSS

       In June 1997, the Financial Accounting Standards Board issued SFAS No.
    130, "Reporting Comprehensive Income," which the Company adopted beginning
    on January 1, 1998. SFAS No. 130 establishes standards for the reporting and
    display of comprehensive income (loss) and its components in a full set of
    general purpose financial statements. The objective of SFAS No. 130 is to
    report a measure of all changes in equity of an enterprise that result from
    transactions and other economic events of the period other than transactions
    with shareholders. Comprehensive income (loss) is the total of net income
    (loss) and all other non-owner changes in equity. For each of the periods
    presented, the Company had no such transactions, therefore the comprehensive
    loss was equal to net loss.

    STOCK-BASED COMPENSATION PLANS

       Effective January 1, 1996, the Company adopted the disclosure provisions
    of SFAS No. 123, "Accounting for Stock-Based Compensation." In accordance
    with the provisions of SFAS No. 123, the Company applies Accounting
    Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to
    Employees," and related interpretations in accounting for stock options.

    ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
    "Accounting for Derivative Instruments and Hedging Activities," which
    requires companies to value derivative financial instruments, including
    those used for

                                       33
<PAGE>   34

    hedging foreign currency exposures, at current market value with the impact
    of any change in market value being charged against earnings in each period.
    In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
    "Accounting for Derivative Instruments and Hedging Activities--Deferral of
    the Effective Date of SFAS No. 133" to defer the effective date of SFAS No.
    133 until fiscal years beginning after June 15, 2000. To date, the Company
    has not entered into any derivative financial instrument contracts. Thus,
    the Company anticipates that SFAS No. 133 will not have a material impact on
    its consolidated financial statements.


    3.  CONCENTRATIONS OF CREDIT RISK:

       Financial instruments that potentially subject the Company to
    concentrations of credit risk consist principally of trade receivables, cash
    equivalents and short-term investments. As of December 31, 1999 and 1998,
    approximately 85% and 71%, respectively, of the Company's trade accounts
    receivable balance was represented by three customers and one customer,
    respectively. Although the Company does not require collateral on accounts
    receivable, because the majority of the Company's customers are large,
    well-established companies, it requires stand by letters of credits or
    prepayments on certain sales to foreign and smaller companies. The Company
    provides reserves for credit losses and such losses have been insignificant
    in all periods presented in the accompanying consolidated financial
    statements. With respect to cash equivalents and short-term investments, the
    Company has cash investment policies that limit the amount of credit
    exposure to any one issuer and restrict placement of these investments to
    issuers evaluated as creditworthy.

       In January 1998, the Company entered into a new bank line of credit under
    which up to $6,000,000 is available for borrowings and letters of credit.
    This arrangement was renewed in September 1999 and expires in January 2001.
    Borrowings are limited to an aggregate amount equaling approximately 80% and
    90% of domestic and foreign eligible trade accounts receivables,
    respectively, and 50% of eligible foreign inventories. The line of credit is
    secured by the Company's outstanding trade accounts receivable and
    inventory. The borrowings under the line are due in January 2001 and accrued
    interest at the 30-day LIBOR rate plus 2.25% or the bank's prime rate, at
    the Company's option. Under the agreement, the Company must comply with
    certain financial and other covenants.

       As of December 31, 1999, borrowings outstanding under this agreement were
    $4,338,000 and amounts utilized for outstanding letters of credit were
    $300,000.

       In 1997, the Company borrowed $3,750,000 from a lender to finance
    purchases of fixed assets. The loan accrues interest at 12.5% per annum from
    the date of borrowing, and is secured by a purchase money lien on the
    equipment financed. Principal payments due under the loan at December 31,
    1999, are as follows (in thousands):

       A significant portion of the Company's machinery and equipment is leased
    under agreements accounted for as capital leases. The cost of equipment
    under capital leases included in property and equipment at December 31, 1999
    and 1998 was approximately $6,590,000, and $5,754,000 respectively.

       In March 1999, the Company entered into a new equipment lease agreement,
    under which the Company can finance equipment purchases of up to $3,000,000.
    As of December 31, 1999, the Company had borrowed approximately $1,936,000
    against this agreement. See Note 9 for information regarding warrants issued

       Rent expense for the operating leases was approximately $1,361,000,
    $922,000, $538,000 in 1999, 1998, and 1997, respectively.

       The Company had outstanding a standby letter of credit of $400,000 to
    secure the Company's warranty obligations to one customer relating to
    discontinued product. The letter of credit is secured by a certificate of
    deposit for $125,000. The letter of credit is subject to draw if the Company
    fails to meet its obligation for liquidated damages to the customer for
    downtime.

       In January 1999, the Company entered into an engineering service
    agreement with one of its vendor's for $728,000, which is payable in cash or
    stock at the option of the Company. As of December 31,1999, the Company had
    paid 41,588 shares of Common Stock with a value of $328,000. In November
    1999, the Company agreed to pay the remaining future obligations under this
    agreement in cash.

    CONTINGENCIES

    In 1999, the Company reached a settlement agreement and mutual release with
    a former contract manufacturer. Under the settlement the Company will
    purchase certain component inventory for cash. This settlement is within
    amounts previously reserved for this purpose in the Company's financial
    statements.

    8.  EMPLOYEE BENEFIT PLAN:

       The Company maintains an employee savings plan for all of its full-time
    employees. This plan qualifies under Section 401(k) of the Internal Revenue
    Code (the "Code"). The plan allows employees to make pre-tax contributions
    in specified percentages up to the maximum dollar limitations prescribed by
    the Code. The Company has the option to contribute to the plan, but has not
    made contributions to date.

    9.  CAPITAL STOCK:

    INITIAL PUBLIC OFFERING

       On August 24, 1999, the Company completed its initial public offering of
    5,750,000 shares of common stock at a public offering price of $8 per share.
    The offering resulted in net proceeds to the Company of $42,780,000 after
    payment of the underwriters commission but before deduction of offering
    expenses. Simultaneously with the closing of the initial public offering,
    all of the Company's then outstanding convertible preferred stock was
    automatically converted into an aggregate of 29,902,283 shares of common
    stock.

    CAPITAL STOCK

       The Company's capital stock is divided into two classes: Common Stock and
    Convertible Preferred Stock. Convertible Preferred Stock consisted of Series
    A Convertible Preferred Stock, Series B Convertible Preferred Stock, Series
    C Convertible Preferred Stock and Series D Convertible Preferred Stock.

       At December 31, 1999, 7,907,469 shares of Common Stock were reserved,
    including 7,850,441 shares for issuance under the Company's stock option
    plans, and 57,028 for warrants to purchase Common Stock.

       During 1998, the Company issued 400,000 shares of Common Stock in
    exchange for a full recourse note in the amount of $800,000. The note bears
    interest at 5.44% per annum and is due in April 2002.

    STOCK OPTION PLANS

    1999 Executive Stock Plan

       The 1999 Executive Stock Plan was adopted by the board of directors in
    April 1999 and approved by the shareholders in May 1999. A total of
    1,195,000 shares of

                                       36
<PAGE>   37

    common stock has been reserved for issuance under the 1999 Executive Stock
    Plan. As of December 31, 1999, options to purchase 1,175,000 shares of
    common stock with a weighted average exercise price of $3.50 had been
    issued, and 20,000 shares remained available for future option grants.
    Unless terminated earlier, the 1999 Executive Stock Plan will terminate in
    April 2009. The 1999 Executive Stock Plan does not impose an annual
    limitation on the number of shares subject to options that may be issued to
    any individual employee.

       The terms of options issued under the 1999 Executive Stock Plan are
    generally the same as those that may be issued under the 1996 Stock Option
    Plan. However, all options granted under the 1999 Executive Stock Plan may
    be exercised immediately after the grant date, subject to the Company's
    right to repurchase at cost any shares that remain unvested at the time of
    the optionee's termination of employment. Options granted under the 1999
    Executive Stock Plan generally vest at the rate of 1/4th of the total number
    of shares subject to the options twelve months after the date of grant and
    1/48th of the total number of shares subject to the options each month
    thereafter.

    1997 Directors' Stock Option Plan

       The 1997 Directors' Stock Option Plan (the "Directors' Plan") was adopted
    by the Board of Directors in December 1997 and amended in June 1999. A total
    of 300,000 shares of common stock has been reserved for issuance under the
    Directors' Plan, of which options to purchase 125,000 shares of common stock
    had been granted. Under the Directors' Plan, as amended, each individual who
    first becomes a non-employee director after the effective date of the
    amendment will receive an automatic initial grant of an option to purchase
    10,000 shares of common stock upon appointment or election. Initial grants
    to non-employee directors will be vested and exercisable in full as of the
    date of grant. The Directors' Plan also provides for annual grants of
    options to purchase 10,000 shares of common stock on the first day of each
    fiscal year to each non-employee director who has served on the Board of
    Directors for at least six months, provided that a non-employee director who
    received a 20,000 share initial grant under the original version of the
    Directors' Plan will be eligible to receive an annual grant of an option to
    purchase 5,000 shares of common stock until the first day of the fiscal year
    following the date on which the initial option has fully vested under the
    terms of that option, after which date each director will be eligible to
    receive an annual grant of an option to purchase 10,000 shares of common
    stock. The annual grants to non-employee directors will be vested and
    exercisable in full as of the date of grant. The per share exercise price of
    all stock options granted under the Directors' Plan must be equal to the
    fair market value of a share of the Company's common stock on the date of
    grant of the option. Options granted under the Directors' Plan have a term
    of ten years. However, unvested options will terminate when the optionee
    ceases to serve as a director and vested options will terminate if they are
    not exercised within 12 months after the director's death or disability or
    within 90 days after the director ceases to serve as a director for any
    other reason.

    1995 and 1996 Stock Option Plans

       During 1996, the Company established the 1996 Stock Option Plan (the
    "1996 Plan"). All shares previously available for issuance under the
    Company's 1995 Stock Option Plan are reserved for issuance under the 1996
    Plan. As of December 31, 1999, 8,800,000 shares of Common Stock had been
    authorized for issuance under the 1995 and 1996 Plan, of which 810,981
    shares remained available for future option grants. Under the 1996 Plan, the
    Company may grant incentive stock options or nonstatutory stock options to
    employees, officers, directors and consultants at an exercise price of not
    less than 100% of the fair market value of the Common Stock on the date of
    grant, except that nonstatutory stock options may be granted at 85% of such
    fair market value. Options granted generally become exercisable at a rate of
    one-fourth of the shares subject to the option at the end of the first year
    and 1/48 of the shares subject to the option at the end of each calendar
    month thereafter. However, at the discretion of management, the optionee may
    have the immediate right to exercise the option subject to a restricted
    stock agreement that gives the Company the right to repurchase unvested
    shares at the original issuance price in the event of termination of
    employment. The maximum term of a stock option under the plans is ten years,
    but if the optionee at the

                                       37
<PAGE>   38

    time of grant has voting power of more than 10% of the Company's outstanding
    capital stock, the maximum term is five years. The number of shares reserved
    for issuance under the 1996 stock option plan will be subject to an
    automatic annual increase on the first day of each year beginning from 2001
    through 2005 equal to the least of: 1) 750,000 shares, 2) 3% of our
    outstanding common stock on the last day of the immediately preceding fiscal
    year or 3) a number of shares determined by the administrator.

       The following table summarizes option activity under all option plans
    including the 1997 Director Stock Option Plan, the 1999 Executive Stock
    Option Plan and the 1995 and 1996 Stock Option Plans:

       In January 1996, the Company adopted the provisions of SFAS No. 123,
    which calls for companies to measure employee stock compensation expense
    based on the fair value method of accounting. As allowed by SFAS No. 123,
    the Company elected the continued use of APB Opinion No. 25, with pro forma
    disclosure of net loss determined as if the fair value method had been
    applied in measuring compensation cost. Had compensation cost for the
    Company's stock based compensation awards been determined under the fair
    value method consistent with SFAS No. 123, the Company's net loss would have
    resulted in the following pro forma amounts:

    The fair value of each option grant for the six month period ended December
    31, 1999, was estimated on the date of the grant using the Black-Scholes
    option valuation model with the following assumptions:

    To comply with the pro forma reporting requirements of SFAS No. 123
    compensation cost is also estimated for the fair value of future employee
    stock purchase plan issuances. Therefore, the Company has estimated the
    compensation cost for our first employee stock purchase plan issuance, which
    will be in January 2000. The fair value of purchase rights granted under the
    Purchase Plan is estimated on the date of grant using the Black-Scholes
    option pricing model with the following weighted-average assumptions:

    1999 EMPLOYEE STOCK PURCHASE PLAN

                                       39
<PAGE>   40

       In June 1999, the Board of Directors adopted the 1999 Employee Stock
    Purchase Plan (the "Purchase Plan"). The Purchase Plan is intended to
    qualify under Section 423 of the Internal Revenue Code. A total of 1,000,000
    shares of common stock have been reserved for issuance under the Purchase
    Plan. The number of shares reserved for issuance under the Purchase Plan
    will be subject to an automatic annual increase on the first day of each of
    2001 through 2005 equal to the least of: (1) 250,000 shares, (2) 1% of the
    outstanding common stock on the last day of the immediately preceding fiscal
    year, or (3) a number of shares determined by the administrator. The price
    of shares purchased under the plan will be equal to 85% of the fair market
    value of the Common Stock on the first or last day of the offering period,
    whichever is lower.

    DEFERRED STOCK COMPENSATION

       In connection with the grant of stock options to purchase 2,338,550
    shares of common stock with a weighted average exercise price of $2.84 per
    share to employees during 1998 and 1999, the Company recorded deferred
    compensation of $4,834,000, representing the difference between the
    estimated fair value of the common stock and the aggregate option exercise
    price of such options at the date of grant. This amount is presented as a
    reduction of shareholders' equity and amortized ratably over the vesting
    period of the applicable options (generally four years). Amortization
    expense related to deferred stock compensation was immaterial in 1998.
    Amortization expense related to deferred stock compensation was $1,104,000
    in 1999. Compensation expense is decreased in the period of forfeiture for
    any accrued but unvested compensation arising from the early termination of
    an option holder's services.

    PREFERRED STOCK

    Netro is authorized to issue 5,000,000 shares of undesignated preferred
    stock. The board of directors will have the authority, without any further
    vote or action by the shareholders:

        -  to issue the undesignated preferred stock in one or more series.

        -  to determine the powers, preferences and rights and the
           qualifications, limitations or restrictions granted to or imposed
           upon any wholly unissued series of undesignated preferred stock;
           and

        -  to fix the number of shares constituting any series and the
           designation of that series.

         The rights of the holders of the common stock are subject to, and may
    be adversely affected by, the rights of the holders of any preferred stock
    that may be issued in the future.

</TABLE>


        Warrants to purchase 23,750 shares at $7.00 per share will expire in
    June 2002. Warrants to purchase 5,000 shares at $7.00 per share will expire
    in September 2002. Warrants to purchase 8,997 shares at $7.78 per share will
    expire in February 2003. Warrants to purchase 19,281 shares at $7.78 per
    share will expire in March 2006. The fair value of the warrants was
    estimated at the date of grant using the Black-Scholes model and the value
    was determined to be immaterial.

         All of the outstanding warrants to purchase Preferred Stock were
    converted upon completion of the Company's initial public offering into
    warrants to purchase shares of Common Stock on a one for one basis.

    10.  INCOME TAXES:

       The Company provides for income taxes under the provisions of SFAS No.
    109, "Accounting for Income Taxes." SFAS No. 109 requires an asset and
    liability based approach in accounting for income taxes. Deferred income tax
    assets and liabilities are recorded to reflect the tax consequences on
    future years of temporary differences of revenue and expense items for
    financial statement and income tax purposes. Valuation allowances are
    provided against assets that are not likely to be realized.

       The provision for income taxes differs from the expected tax benefit
    amount computed by applying the statutory federal income tax rate of 35% to
    loss before income taxes as follows:

</TABLE>


       The Company has established a valuation allowance for the total deferred
    tax asset because, given the Company's limited operating history and
    accumulated deficit, it is uncertain that the deferred tax asset will be
    realized.

       As of December 31, 1999, the Company had Federal and State net operating
    loss carryforwards of approximately $87,479,278 and $24,208,734,
    respectively. The Company's net operating loss carryforwards expire at
    various dates through 2019. Under current tax law, the net operating loss
    and tax credit carryforwards available for use in any given year may be
    limited upon the occurrence of certain events, including significant changes
    in ownership interest.

    11.  SEGMENT REPORTING:

       In June 1997, the Financial Accounting Standards Board issued SFAS No.
    131, "Disclosures About Segments of an Enterprise and Related Information."
    The Company adopted SFAS No. 131 in fiscal 1998. SFAS No. 131 establishes
    standards for disclosures about operating segments, products and services,
    geographic areas and significant customers. The Company is organized and
    operates as one operating segment: the design, development, manufacturing,
    marketing and selling of broadband wireless point-to-multipoint access
    systems.

       The Company markets its products in the United States and in other
    foreign countries through worldwide system integrators, its direct sales
    force and local resellers. Revenue by country based on sales to those
    customers before distribution to the end customer was as follows:

    12. SUBSEQUENT EVENT (UNAUDITED)

    2000 Non-Executive Stock Option Plan

         The 2000 non-executive stock option plan was adopted by the Board of
    Directors in February 2000 and, unless terminated earlier by the Board of
    Directors, will terminate in February 2010. It does not require shareholder
    approval. The 2000 non-executive stock option plan provides for the grant of
    nonstatutory stock options to non-executive employees of and consultants to
    the Company. The purposes of the 2000 non-executive stock option plan are:
    to attract and retain the best available personnel; to provide additional
    incentives to our non-executive employees and consultants; and to promote
    the success of the Company. The Company has reserved 2,000,000 shares for
    issuance under the 2000 non-executive stock option plan.

         The compensation committee currently administers the 2000 non-executive
    stock option plan. The administrator of the plan determines: the number of
    shares subject to options, provided that no individual employee may receive
    option grants for more than 1,000,000 shares; vesting schedules, which are
    typically 1/4(th) after one year and 1/48(th) per month thereafter; exercise
    prices, which must be at least 85% of the fair market value of our common
    stock; the term of the options, which may not exceed ten years; and the
    transferability of the options, which are generally non-transferable other
    than by will or the laws of descent or distribution, unless otherwise
    determined by the administrator.

         Options granted under the 2000 non-executive stock option plan are also
    subject to the following restrictions: options granted under the 2000
    non-executive stock option plan are only nonstatutory stock options; and
    executive officers of the Company may not receive grants under the plan.

         In the event of a change of control of the Company, outstanding options
    will be assumed or substituted by the successor corporation. If the
    successor corporation does not agree to this assumption or substitution, the
    options will terminate upon the closing of the transaction. The Company's
    board of directors may amend, modify or terminate the 2000 non-executive
    stock option plan if the amendment, modification or termination does not
    impair vesting rights of the plan participants.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE



To the Board of Directors and Shareholders of
Netro Corporation:

     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Netro Corporation (a California
corporation) and subsidiaries included in this registration statement and have
issued our report thereon dated January 24, 2000. Our audits were made for the
purpose of forming an opinion on the basic financial statements taken as a
whole. The schedule listed in the exhibit index above is the responsibility of
the Company's management, is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements, and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.
