OVERVIEW

    Interwave Communications International, Ltd., ("we," "us," "the Company," or
"interWAVE") is a provider of compact wireless communications systems using GSM,
an international standard for voice and data communication. We have pioneered
what we believe is the only commercially available system that provides all of
the infrastructure equipment and software necessary to support an entire
wireless network within a single, compact enclosure. We have designed our
systems to serve the following applications:

    - WIRELESS OFFICES. Our systems allow wireless users in organizations such
      as large corporations, government entities and universities to maintain
      contact with the organization's private telephone network whether the
      users are in their offices, out of their offices or moving between
      locations.

    - COMMUNITY NETWORKS. Our systems enable wireless service providers to add
      capacity in heavy usage areas and to provide telephone service in
      previously unserved communities.

    - SPECIALIZED NETWORKS. The compact nature of our systems allows innovative
      uses of these systems in applications previously impossible. These include
      the deployment for emergency applications, military applications and
      cellular usage on airplanes.

    Our core product, WAVEXpress, delivers a comprehensive set of wireless
network capabilities which are based on the GSM standard. Our patented
WAVEXpress systems can serve as:

    - a base station to receive and transmit voice and data signals over radio
      frequencies;

    - a switch to route voice and data signals to their correct destinations;

    - a base station controller to manage voice and data signals between the
      base station and the switch; or

    - any combination of these functions depending on our system's hardware and
      software configuration.

    Our all-in-one solution, the Network In A Box, provides the capabilities of
a complete GSM network in an enclosure approximately the size of a personal
computer tower. Our system is designed to use the Internet Protocol, the
networking standard used to communicate across the Internet. We believe this
design provides us with an important competitive advantage because we believe
the next generation of wireless standards will be based on the Internet
Protocol.

                                       1

    We market and sell our solutions around the world utilizing a three-tiered
sales strategy which includes selling to communications equipment providers, to
systems integrators which integrate our systems with the products of other
companies and through our own direct sales force. Since 1997 we have sold over
1,800 units which have been installed in 24 countries worldwide. We have
established a wide-ranging strategic alliance with Nortel Networks, which
accounted for 28% and 51% of our revenues in 2000 and 1999, respectively and
which owns 17.1% of our fully diluted shares. We have a strategic alliance with
Alcatel Business Systems, which included the purchase of 4.3% of our fully
diluted shares. These alliances include purchase and distribution agreements
through which both companies market our products to their customers. In addition
to Nortel Networks and Alcatel, we have a strategic relationship with Hutchison
Whampoa, one of the leading global GSM cellular operators. Hutchison affiliates
own 5.5% of our fully diluted shares; Hutchison affiliates have deployed our
products in networks in Hong Kong, Sri Lanka, and India.

INDUSTRY

RAPID GROWTH FOR MOBILE WIRELESS COMMUNICATIONS

    In recent years, worldwide demand for mobile wireless communications has
increased dramatically. According to The Strategis Group, the worldwide wireless
market is expected to grow from 450 million users in 1999 to approximately
1.2 billion by 2004, a compounded annual growth rate of approximately 22%. The
increasing availability, functionality and affordability of wireless products
and services have driven this rapid growth.

    Changes in the worldwide regulatory environment, including the elimination
of monopolies for public communications services, privatization of
government-owned communications organizations and competitive licensing of radio
frequency spectrum by regulatory authorities, have led to an increase in the
number of communications service providers seeking to meet the rapidly growing
demand for mobile wireless communications. In Europe, for example, recent
European Union directives prohibit member countries from restricting competitive
access to mobile and local service after January 1, 1998. In the United States,
the Telecommunications Act of 1996 opened local telephone networks to new
competition. Similar trends in developing countries are creating significant
opportunities for new entrants in the communications market. This increasingly
competitive environment is rapidly driving down the prices that end-users pay
for services.

COMMUNICATIONS EQUIPMENT MARKET

    Wireless service providers are investing in expanding and upgrading their
networks to add capacity and keep pace with the demand for value-added services.
These investments are being driven by increased competition, strong subscriber
growth and new product innovation. Such investments enable wireless service
providers to extend geographic coverage, improve call quality, and deliver
enhanced features and services. Despite reductions in the cost of communications
equipment, service providers' capital budgets have continued to increase
substantially. According to industry sources, the digital wireless
communications equipment market is expected to grow from approximately
$38 billion in 1999 to $141 billion in 2003. Growth rates experienced by the
industry as a whole may not, however, reflect growth rates that we will
experience.

GLOBAL SYSTEM FOR MOBILE COMMUNICATIONS STANDARD

    The GSM standard competes primarily with the code division multiple access
standard, or CDMA, the time division multiple access standard, or TDMA, and
analog standards. According to The Comprehensive Guide to Wireless Technologies,
all of the digital standards, including GSM, CDMA and TDMA, offer clearer voice
communications than the older analog standards. We believe that digital
standards will attract even more users in the future, as functions such as
high-speed data

                                       2
<PAGE>
communications become available. The GSM standard allows users to receive text
messages and allows users to roam across international boundaries without an
interruption in service. The TDMA and CDMA standards provide similar advanced
messaging capabilities, but do not allow users to roam internationally because
the phones do not have a removable personal identity card, like GSM phones, to
identify the user to the network regardless of location. Without this portable
identity card, roaming of the user's phone is limited to networks that operate
in the same frequency range as the user's home network. Finally, CDMA, which
uses a wide frequency range with unique mathematical codes to distinguish
different users, does not have a maximum number of calls it can handle at a
given time, but rather can accommodate additional calls by slightly degrading
the quality of all ongoing calls. GSM and TDMA, which transmit and receive
information in predefined time slots in a narrowly defined frequency range,
cannot expand the maximum number of calls to accommodate such surges in demand.

    According to The Strategis Group, GSM is the world's most widely accepted
digital wireless standard with 290 million users in 1999 and is projected to
grow to over 700 million users by 2004. In 1999, GSM accounted for approximately
68% of the world's wireless market while CDMA, TDMA and analog accounted for 9%,
6% and 9% of the world's market, respectively. According to Frost & Sullivan,
154,000 GSM base stations were installed in 1999 and in 2002 they expect 400,000
GSM base stations to be installed. GSM is the dominant standard in Europe as a
result of the European Union's decision to endorse a single unifying digital
standard in the 1980s. In Asia, the rate of acceptance of the GSM standard is
growing rapidly as wireless service providers have selected GSM to offer
differentiated services and to increase capacity. On November 1, 1999, the GSM
Association and the Universal Wireless Communications Consortium, the governing
bodies of the GSM and TDMA standards, respectively, announced an agreement to
jointly develop standards that enable GSM and TDMA systems to operate together.
International standards organizations are also working to develop the next
generation of standards that will replace all three of these technologies.

    Early in the history of the wireless market, analog standards achieved a
strong presence in the United States while the GSM standard was being adopted in
Europe. According to the Yankee Group, at the end of 1999, 17% of the
86 million wireless users in the United States were using the GSM standard, up
from 3% in 1998. They project the total number of users to grow to 200 million
in the United States by 2005. Today, although the acceptance of the GSM standard
in North America is in its early stages, increased penetration of the GSM
standard is being driven by its ability to support international roaming, and
will be further driven by its advanced data transmission and messaging
capabilities. GSM has been adopted in North America by communications service
providers, including Microcell, PacBell VoiceStream, and Powertel. Both CDMA and
TDMA also have significant presence in the United States. Sprint PCS and GTE
have deployed CDMA. AT&T Wireless has deployed TDMA.

FUTURE WIRELESS STANDARD

    An international consortium of standards bodies is working to establish the
specifications of the next generation of wireless standards, often referred to
as the third generation wireless standard, and to ensure its interoperability
with existing network standards. Since the installed base of wireless networks
was not designed to be interoperable with what we expect will be the third
generation standard, significant capital expenditures will be required to update
these networks. We believe wireless service providers will attempt to preserve
their previous investments in infrastructure and will seek incremental solutions
that will facilitate upgrading to the third generation wireless standard while
ensuring interoperability among disparate networks. Industry analysts expect the
third generation standard to use the Internet Protocol to enable high-speed data
transmissions over wireless networks. The Internet Protocol is the networking
standard used to communicate voice and data across the Internet. Using this
protocol in a wireless network would give users access to Internet resources
that might otherwise be unavailable and will provide potential cost-savings for
operators by allowing them to use existing

                                       3
<PAGE>
Internet Protocol systems. We expect these developments will increase the demand
for cost-effective, flexible, wireless networks that can be easily upgraded to
the emerging future generation standard. According to The Strategis Group,
wireless messaging or data transmission devices in use will expand from
230 million in 2001 to over 1 billion by 2004.

KEY DEVELOPING MARKET OPPORTUNITIES

    Rapid technological innovation is creating new and varied market
opportunities in wireless communications.

    WIRELESS OFFICES.  Wireless office networks combine the mobility and
flexibility of wireless communications with all of the features of traditional
wireline networks, and enable organizations such as large corporations,
government entities and universities to integrate their private office networks
with public wireless networks. This integration enables abbreviated dialing
while the user remains within the private office network. After the user leaves
the office building, incoming calls are routed to the user's mobile phone via
the public wireless network. Wireless office networks can increase productivity
by making it possible to reach employees through a single phone number at all
times, regardless of location, while providing significant cost savings for the
organization. While the competing digital European cordless telephone standard,
also known as DECT, had a larger installed base of 1.6 million lines, in
wireless offices in Europe, compared to 410,000 lines for GSM, the DECT standard
does not permit roaming outside the office premises. While some handset vendors
either offer or are considering offering phones that support both DECT and GSM,
according to the Yankee Group there is expected to be a limited market for such
a product for both technical and economic reasons. The Yankee Group estimates
the market for these GSM-based wireless office networks will be 10.9 million
distinct phone lines in 2002 in the corporate market alone. The wireless office
market enables wireless service providers to expand their customer base, reduce
subscriber turnover, provide customized billing and establish a presence from
which to offer wireless data networks.

    COMMUNITY NETWORKS.  Community networks enable the introduction of wireless
service to areas that are currently not served by wireless providers or that may
not have any telephone service. Wireless solutions such as wireless local loop
networks offer the most cost-effective way to provide telephone service to areas
with no current service. Wireless local loop networks are wireless
communications systems that connect users to the public telephone network using
radio signals as a substitute for traditional landline connections. These
markets offer substantial growth potential due to the relatively low level of
rural and remote telephone service penetration and the continued need for
low-cost communications services. According to Frost and Sullivan, the wireless
local loop equipment market is expected to grow from $1.0 billion in 1999 to
$3.5 billion in 2005. In addition, the wireless solutions provide a high-value
proposition in developing countries since these solutions are generally less
expensive because of the lack of an established infrastructure in these
countries. To succeed in the community networks market, we believe wireless
service providers need to employ network systems that minimize initial capital
expenditures while providing the flexibility to scale cost-effectively as demand
grows. In addition, wireless service providers need to minimize ongoing
operating costs, the largest of which are the charges associated with routing
calls through a central switch.

PRIMARY OBJECTIVES OF THE WIRELESS SERVICE PROVIDER

    To better serve their existing user base and to gain market share, wireless
service providers are focused on the following primary objectives:

    COST-EFFECTIVE NETWORK DEPLOYMENT.  The deployment of traditional wireless
networks requires significant capital expenditures. A typical wireless network
consists of a switch to route voice and data signals to their correct
destinations, multiple base station controllers to aggregate and manage voice
and data signals between the switch and the base transceiver station and many
base transceiver stations

                                       4
<PAGE>
to transmit and receive voice and data signals over radio frequencies. Wireless
networks are typically designed to support large user bases. Service providers
need cost-effective ways to address smaller user bases. As service providers
face increasing price competition, they will depend on communications equipment
providers for cost-effective and technologically advanced infrastructure
systems.

    EXTENSION OF COVERAGE.  In the past, wireless networks have been deployed
primarily in urban centers and other heavy usage areas. Increasing demand for
improved service over wider geographic areas has prompted wireless service
providers to accelerate the expansion of their networks. In addition, wireless
service providers are deploying networks in locations where service has
previously been inadequate or prohibitively expensive to provide.

    IMPROVED QUALITY OF SERVICE.  Currently, wireless networks in metropolitan
areas are prone to a lower quality of service when heavy usage causes capacity
limits to be exceeded. Furthermore, wireless service in buildings, tunnels and
subways is often interrupted or unavailable. Similarly, wireless services in
remote areas are often limited due to the lack of a fully-developed wireless
infrastructure. Improving the quality of wireless service involves increasing
network capacity and capabilities to address current network constraints.

    VALUE-ADDED SERVICES.  The extreme competition faced by wireless service
providers requires them to offer differentiated, value-added services including
the ability to roam across regional, national and international boundaries
without an interruption in service, access to high-speed data transmission and
other features such as voicemail and caller ID. In order to address increasing
competitive pressures, wireless service providers must use flexible systems that
enable them to deploy numerous services in a timely and cost-efficient manner.

    As wireless service providers seek to achieve these objectives in an
extremely competitive market, they will increasingly require communications
equipment providers to develop wireless network solutions that enable the
flexible, cost-effective delivery of value-added services and that are capable
of being easily adapted to the third generation wireless standard.

THE INTERWAVE SOLUTION

    Our systems offer a number of important advantages to GSM service providers,
including:

COMPACT, FLEXIBLE AND MODULAR

    Our WAVEXpress products provide a comprehensive set of GSM network
capabilities. We believe that we provide the only commercially available system
that supports an entire GSM network within a single enclosure approximately the
size of a personal computer tower. The patented WAVEXpress system can serve as a
base station, base station controller, switch or any combination of these
functions depending on our system's hardware and software configuration. The
WAVEXpress product is modular, using only four hardware modules which enable the
system to be updated and enhanced by simply exchanging specific hardware modules
and upgrading software. Our compact and modular system enables wireless service
providers to implement wireless office networks, to fill in coverage blind
spots, to increase capacity in heavy usage areas and to provide service to
previously unserved areas.

COST-EFFECTIVE NETWORK DEPLOYMENT AND OPERATION

    Our compact, flexible systems enable us to be a price leader, reducing both
initial and incremental capital expenditures for network deployment by wireless
service providers. The flexible nature of our products enables wireless service
providers to rapidly add capacity to their networks. In addition, there are only
four WAVEXpress hardware modules, which result in reduced maintenance and
training costs, and a reduction in capital necessary to maintain spare parts in
inventory. Furthermore, we have a patented switching technology that allows the
network to determine whether a call should be directed

                                       5
<PAGE>
to its destination by the local network or by a central office. This proprietary
switching capability allows a wireless service provider to reduce its dependence
on central office switching equipment and increase network efficiency, resulting
in lower operating costs.

INTEROPERABILITY WITH EXISTING GSM NETWORKS

    We maintain strict adherence to GSM standards to ensure that our systems are
compatible with other communications equipment providers' products. We have
proven our systems' interoperability in live networks with equipment from all
major communications equipment providers, including Alcatel, Ericsson, Lucent,
Nokia, Nortel Networks and Siemens. Our systems are also compatible with
existing private telephone systems. Interoperability enables wireless service
providers to upgrade their existing systems without having to replace their
entire network, facilitating the introduction of new capabilities and services
in a timely and cost-effective manner. We plan to maintain our systems'
interoperability despite changes to software, equipment configuration, network
design and upgrades to the various network standards.

RAPID TIME-TO-MARKET FOR NEW, VALUE-ADDED SERVICES

    Service providers using our wireless network systems can achieve rapid
time-to-market for new services which they can offer to new and existing users.
Our flexible design enables the system to be readily upgraded through simple
hardware additions and software reconfigurations. These features allow service
providers to decrease the implementation time required to offer new services to
customers. Our WAVEView products also allow for the control of all functions and
components of the network through a single management system. This enables
service providers to customize and expand service offerings to users without
deploying additional systems that require incremental training and testing. Our
systems provide small, scalable and low-cost alternatives to expensive digital
communications infrastructure equipment. Furthermore, since our systems are
based on the Internet Protocol, we believe wireless service providers will be
able to easily adapt to the third generation wireless standard through simple
software upgrades or specific hardware replacements, instead of time-consuming
deployment of and costly investment in new network equipment.

STRATEGY

    Our goal is to be the premier global provider of cost-effective, compact
wireless systems in targeted segments of the GSM market. The key elements of our
strategy include:

PROVIDE GSM WIRELESS OFFICE SYSTEMS

    We intend to provide cost-effective network systems for large organizations
such as corporations, universities and government entities. We have developed a
wireless office system that can function as a stand-alone network or as an
add-on to a new or existing network. Our system, and specifically our patented
switching technology, reduces costs for an organization by allowing a user's
calls to any campus to stay inside the organization's network. Nortel Networks
and Alcatel are actively marketing our wireless office system.

DELIVER NEXT GENERATION INTERNET PROTOCOL-BASED SOLUTIONS

    Our research and development efforts are focused on using our WAVEXpress
products to offer voice and data communications over the Internet using the GSM
standard. We plan to capitalize on the flexibility of our system design to speed
our customers' transition to the emerging third generation standard once its
specifications are finalized. Our fully-functional, GSM voice communications
system that uses the Internet Protocol was demonstrated at the February 1999 GSM
World Congress.

FURTHER PENETRATE EXISTING MARKET OPPORTUNITIES

    To date, our sales have been predominantly to wireless service providers
seeking to fill gaps in coverage, to increase capacity in heavy usage areas and
to provide wireless service to previously unserved areas. We believe that these
applications will continue to represent a significant market opportunity for our
systems. As our customers expand their networks, we plan to generate additional
orders. We intend to convert existing trials into large-scale commercial
deployments. Currently, we are involved in 16 trials in nine countries. We also
believe that our visibility as an early provider of network solutions based on
the Internet Protocol will lead to new deployments with new and existing
customers. For example, Alcatel has integrated our products based on the
Internet Protocol with their corporate office networking products and will be
marketing them through their enterprise solutions division.

STRENGTHEN AND EXPAND RELATIONSHIPS WITH COMMUNICATIONS EQUIPMENT PROVIDERS

    We intend to use our strategic relationships with communications equipment
providers such as Nortel Networks, Alcatel and Sagem to expand our geographic
coverage and increase the market share for our solutions. Our relationships with
these equipment providers allow us to benefit from their sales forces selling
our products and enable us to reach new customers and strengthen our position
with existing customers. Communications equipment providers bundle our solutions
with their products to address the needs of wireless service providers. Our
sales are also enhanced by equipment providers' abilities to offer service and
support for our systems. We believe that strengthening these relationships and
selectively establishing new relationships will help us to generate new sales.

USE TECHNOLOGICAL LEADERSHIP TO PROVIDE COMPETITIVE ADVANTAGES FOR WIRELESS
  SERVICE PROVIDERS

    We intend to use our leading-edge technology and intellectual property to
expand the capabilities of our network systems, streamline system upgrades and
simplify the purchasing process. Furthermore, we intend to update our equipment
to use the latest generation Power PC which will provide significantly more
processing power and enhance service providers' ability to handle heavy data
usage. Upcoming enhancements to our systems include the implementation of a
Web-based system to manage wireless networks, which will provide all monitoring,
configuration and maintenance capabilities. This will enable rapid emergency
response and enhance overall system management. Finally, we intend to develop a
Web-based system to enable service providers to configure and purchase our
solutions online, streamlining the purchasing process and reducing related
purchasing costs.

PRODUCT LINES

WAVEXPRESS

    Our core WAVEXpress product can house any combination of our switch, our
base station controller and our base station in a single compact enclosure. The
WAVEXpress system is approximately the size of a personal computer tower and
weighs less than 50 pounds. Our WAVEXpress product line represented 84%, 80% and
86% of our net revenues for fiscal year ending June 30, 1998, 1999 and 2000,
respectively.

    WAVEXCHANGE.  The WAVEXchange is a wireless switch that routes calls and is
designed to allow the network to process calls locally rather than at a central
switch, thereby reducing operating costs. The small size and configurability of
the WAVEXchange enable wireless service providers to deploy value-added services
rapidly. The WAVEXchange can be integrated with existing private telephone
networks. The patented WAVEXchange is the only GSM switch on the market that can
act either as a base station controller extension of a central switch or as a
local switch, on a call-by-call basis. The WAVEXchange uses standard GSM
interfaces and can be configured with up to 16 connections that support up to
4,000 users, depending on the requirements of the network. We began shipping
WAVEXchange products in June 1998.

                                       7
<PAGE>
    WAVEXPRESS/BSC.  The WAVEXpress/BSC is a compact base station controller
that aggregates and manages the communications between the WAVEXpress/BTS and
the central switching equipment or a local WAVEXchange switch. The
wall-mountable WAVEXpress/BSC, one of the smallest GSM base station controllers
on the market, connects to any main switching center supporting the GSM
standard. The WAVEXpress can be configured with up to 16 connections depending
on the requirements of the network. We began shipping the WAVEXpress/BSC in
December 1996.

    WAVEXPRESS/BTS AND TURBOWAVE/BTS.  The WAVEXpress/BTS is a base transceiver
station which accommodates up to three radios providing up to 22 simultaneous
communication channels. Versions of the WAVEXpress/BTS are available in all
three GSM frequency bands: 900 Mhz and 1800 Mhz for Europe and Asia and 1900 Mhz
for the Americas. The WAVEXpress/BTS connects the user to the network with no
need for additional components. In addition, we offer a higher powered version
of the WAVEXpress/BTS, the TurboWAVE, which is available in two configurations.
The TurboWAVE offers broader geographic coverage with over 20 kilometers of
range. In covering a longer range, the TurboWAVE offers the service provider
benefits from increased coverage, greater reduction in transmission costs and
lower infrastructure costs per user. We began shipping the WAVEXpress/BTS in
December 1996 and the TurboWAVE/BTS in December 1997.

    WAVEXPRESS/TURBOMAX.  The WAVEXpress/TurboMAX is a high power macro network
product for the community market. TurboMAX offers wireless community network
service providers a cost-effective, easy-to-install macro network solution with
interWAVE's current WAVEXpress micro footprint.

    Designed as an integral part of interWAVE's suite of wireless network
products, TurboMAX shares a common hardware platform with increased power and
receive sensitivity that seamlessly interoperates with all other major wireless
networks. TurboMAX uses 40-watt power amplifiers per transceiver with a unique,
patented thermal technology developed initially for military applications.
Introduced in July 2000, shipments are expected before the end of the calendar
year 2000.

    NETWORK IN A BOX.  The Network In A Box offers the ability to support a
complete GSM network by integrating the switch, base station controller and base
station in a single WAVEXpress unit. The Network In A Box is designed for rapid
deployment and provides easy network expansion as usage and coverage
requirements increase. Ideally suited for wireless office networks, the Network
In A Box can support a stand-alone GSM network or it can integrate with most
private telephone networks to provide wireless GSM interoperability with a
corporate wireline network. We have a patented switching technology that allows
a single Network In A Box to act as a wireless extension to a private telephone
network and as an extension to a public wireless network on a call-by-call
basis. In remote and rural communities, the Network In A Box enables rapid
deployment of GSM capabilities. Since a high percentage of calls stay within the
local network, transmission costs associated with dependence on a central switch
are minimized. Coverage and capacity can be increased quickly and easily by
adding WAVEXpress/BTS and WAVEXpress/BSC units to the network. The Network In A
Box can also serve as a cost-efficient GSM starter network allowing wireless
service providers to match their infrastructure expenditures to usage growth. We
began shipping the Network In A Box in August 1998.

    WAVEXPRESS/BS PLUS.  The WAVEXpress/BS Plus combines the functions of a base
station controller and base station in a single product. A WAVEXpress/BS Plus
can support up to 600 users and up to three external WAVEXpress/BTS base
stations to serve up to 2,400 users. We began shipping the BS Plus product in
March 2000.

WAVEVIEW

    WAVEVIEW.  The WAVEView (OMC) is an operations and management control system

COMMUNICATIONS EQUIPMENT PROVIDERS

    NORTEL NETWORKS.  In March 1998, we entered into a five-year purchase and
distribution agreement with Nortel Networks. According to the terms of the
agreement, Nortel agrees to purchase a specified volume of our products to meet
quarterly purchase commitments. In addition, the agreement lists certain
features that our products must contain by various milestone dates. The
agreement precludes us from entering into similar agreements with two
telecommunications companies until January 2001.

    The agreement was amended in April 1999 with respect to Nortel Networks'
obligations to meet specific quarterly purchase commitments and to specify our
requirements to meet certain product development milestones that are important
to Nortel Networks. In the first nine quarters since the original agreement was
executed, Nortel Networks has purchased nearly $20 million of our products.

    The agreement with Nortel Networks is one of a number of agreements executed
as part of a strategic alliance between our two companies. We also entered into
a patent license agreement whereby we acquired a license to certain GSM patents
held by Nortel Networks and a technical information agreement whereby services
for systems testing facilities and equipment are provided. We have entered into
a number of financing transactions with Nortel Networks. Nortel Networks has
made an aggregate investment of $29.5 million in our company consisting of
$25.0 million in cash and delivery of license and technical information
agreements valued at $4.5 million. Assuming the exercise of all outstanding
warrants held by Nortel Networks, they own approximately 17.1% of our common
shares.

    ALCATEL.  In July 1998, we entered into a two-year, non-exclusive purchase
and distribution agreement with Alcatel CIT. This agreement targeted specific
wireless service providers located in Western Europe where Alcatel has a
significant supplier presence. In November 1999, we entered into a new two-year,
non-exclusive purchase and distribution agreement with Alcatel Business Systems.
Under this agreement, Alcatel will integrate our products, including our product
based on the Internet Protocol, with their corporate office networking products
and market them through Alcatel's enterprise solutions division to their mobile
operator customers. Alcatel, which has minimum purchase commitments through
December 2001 under the agreement, intends to resell our products primarily to
their corporate office customers. Under the Agreement, we agree to modify our
products to contain certain features by various milestone dates.

    In November 1999, Alcatel invested approximately $12.2 million in our
company by purchasing for cash approximately 1.5 million preferred shares at
$8.00 per share. In January 2000, Alcatel purchased an additional 500,000 common
shares at $13.00 per share as part of our initial public offering. As a result,
Alcatel currently owns approximately 4.3% of our fully diluted shares. Through
June 30, 2000, Alcatel had purchased approximately $3.8 million of our products
and services.

SYSTEMS INTEGRATORS

    ADC TELECOMMUNICATIONS/MICROCELLULAR SYSTEMS.  In early 1997, we entered a
four-year, non-exclusive distribution agreement with ADC
Telecommunications, Inc., which led to nearly $9.8 million in revenue between
1997 and early 1999. In May 1999, ADC Telecommunications assigned the agreement
to Microcellular Systems, Ltd., a company started by former ADC
Telecommunications mobile systems division employees. Microcellular Systems,
headquartered in the U.K., is targeted at providing systems integration and
service/support to specific key wireless service providers in Western Europe.
Microcellular Systems accounted for $1.3 million of our revenue representing 4%
of our net revenue for the fiscal year ended June 30, 2000. Microcellular is not
currently obligated to meet any minimum volume purchase commitments. ADC
Telecommunications also provided us with development support and testing
services. Between July 1998 and March 1999, we worked closely with the company
to jointly develop products for the North American market. In conjunction with
this activity, ADC Telecommunications acquired 360,000 shares of our preferred
shares in exchange for development services valued at approximately
$2.5 million. This agreement concluded in May 1999.

    HANGZHOU TOPPER ELECTRIC CORPORATION.  In June 1999, we began selling our
products in China to HangZhou Topper Electric, a private company incorporated in
China. We have sold $3.8 million of our products to HangZhou Topper Electric
through June 2000. We have entered into a joint venture agreement with HangZhou
Topper Electric whereby the joint venture will manufacture our products for the
Chinese market, as well as develop new products. HangZhou Topper Electric is not
currently obligated to meet any minimum volume purchase commitments.

DIRECT SALES

    We established a direct sales presence in Hong Kong in late 1995 and in
Paris in mid-1996. We have established a five-year cooperation agreement with
Telstra, headquartered in Australia. We have a multi-year cooperation agreement
with France Telecom, headquartered in Paris, providing us with information
sharing opportunities with France Telecom. Through wireless service providers,
Hutchison Telecommunications (Hong Kong), a unit of Hutchison Whampoa, Total
Access Communications, a subsidiary of UCOM Group of Thailand, Lanka Cellular

and Hutchison MAX, we have deployed our network solutions in Hong Kong, Bangkok,
Sri Lanka and India, respectively.

    HUTCHISON TELECOMMUNICATIONS GROUP.  We began deploying our products in Hong
Kong with Hutchison Telecommunications Group in 1997. In December 1999, we
executed a contract with an affiliate of Hutchison Telecommunications Group to
deploy our products in Sri Lanka. In addition, Holodeck Limited, an affiliate of
Hutchison Telecomunications Group and a wholly-owned subsidiary of Hutchison
Whampoa, purchased for cash 2 million preferred shares at $8.00 per share. As a
result, Holodeck Limited increased its beneficial ownership to 2.6 million
shares, or 5.5% of our outstanding shares.

    In connection with our contract with an affiliate of Hutchison
Telecommunications Group to sell our products in Sri Lanka and India, we entered
into an exclusivity agreement in which we agreed not to sell our WAVEXchange and
WAVExpress products to any party in Sri Lanka other than Hutchison's affiliate
for a period of three years. This period will be extended two years if at the
end of the three year period Hutchison's affiliate has ordered equipment in the
aggregate value of $15 million.

CUSTOMER SUPPORT--CUSTOMER ADVOCACY/ENGINEERING SERVICES

    Our support organization provides pre-sale, installation and post-sale
support to wireless service providers who have purchased systems directly from
us. We offer 24-hour telephone support 7 days a week. We provide manuals and
extensive training to support deployment and operation of our systems. We offer
an ongoing maintenance program for our products, consisting of product
enhancements, product updates and technical support. System operators may renew
maintenance and support on an annual basis by paying a maintenance fee. We also
provide extensive support to communication equipment providers and systems
integrators through product training, 24-hour help-desk support and emergency
problem resolution. In addition, we work closely with our customers' first-line
support organizations to insure that they have the necessary skills and specific
product knowledge to assist their customers with installation, management and
other network support requirements.

RESEARCH AND DEVELOPMENT

    To maintain our technology leadership position, we focus our research and
development efforts on improving the functionality and performance of our
current products and developing new products. We obtain extensive development
input from our customers and actively monitor changes in the marketplace. We are
currently investing significant resources to:

    - develop high-speed data capabilities while significantly reducing
      manufacturing costs;

                                       13
<PAGE>
    - expand the capacity of our base station;

    - modify our WAVEView management system to adapt to the Internet Protocol;
      and

    - deliver product enhancements that allow communications equipment providers
      to offer additional value-added services required by wireless service
      providers.

    We believe our future success will depend, in part, on our ability to
continue to develop and introduce new products and enhancements to our existing
products. Our research and development expenditures totaled approximately,
$15.3 million, $14.2 million and $18.1 million in the fiscal years ended
June 30, 1998, 1999 and 2000, respectively.

    We perform our research and product development activities in our Menlo Park
and Hong Kong offices. As of June 30, 2000, our research and development staff
consisted of 103 full-time or contracted employees that we supplement from time
to time with independent contractors and outside development resources.

PROPRIETARY RIGHTS

    Our success and ability to compete depends in part upon our proprietary
technology. We rely on a combination of patent, copyright and trade secret laws
as well as non-disclosure agreements to protect our proprietary technology. We
currently hold 19 United States patents and have 14 United States patent
applications pending. Many of these patent applications have also been filed in
a number of other countries. We cannot be certain that patents will be issued
with respect to pending or future patent applications or that our patents will
be upheld as valid or will be sufficient to prevent the development of
competitive products. We seek to protect our intellectual property rights by
limiting access to the distribution of our software, documentation and other
proprietary information. In addition, we have entered into confidentiality
agreements with our employees and certain customers, vendors and strategic
partners. Despite these efforts, it may be possible for unauthorized third
parties to copy certain portions of our products, to design around our patents,
or to reverse-engineer or otherwise obtain and use our proprietary information.
In addition, we cannot be certain that others will not develop substantially
equivalent or superseding proprietary technology, or that equivalent products
will not be marketed in competition with our products, thereby substantially
reducing the value of our proprietary rights. We are also subject to the risk of
adverse claims and litigation alleging infringement of the intellectual property
rights of others. In this regard, there can be no assurance that third parties
will not assert infringement claims in the future with respect to our current or
future products or that any such claims will not require us to enter into
license arrangements or result in protracted and costly litigation, regardless
of the merits of such claims.

    No assurance can be given that any necessary licenses will be available or
that, if available, such licenses can be obtained on commercially reasonable
terms. In addition, the laws of some countries do not protect our proprietary
rights to the same extent as do the laws of the United States. Accordingly, we
may not be able to protect our proprietary rights against unauthorized
third-party copying or use, which could significantly harm our business.

    In March, 1998, we acquired a license to certain GSM related patents held by
Nortel Networks in conjunction with Nortel Networks' equity investment in our
company.

MANUFACTURING

    We rely heavily on contract manufacturers to provide labor and
capital-intensive production capacity. We currently use a single primary
contractor--Pemstar, Inc., which is responsible for the manufacture of most of
our digital and radio modules. Pemstar has over 179,000 square feet of
manufacturing space in San Jose, California. Our initial manufacturing agreement
with Pemstar was signed in October 1995.

                                       14
<PAGE>
    While relying on contractors for most of our manufacturing needs, we also
conduct final assembly and systems test operations at our Menlo Park facility.

    Since we typically have long sales cycles, we rely on a detailed sales
forecast to determine our production requirements and meet the ordering needs of
our contract manufacturers. We utilize the sales forecast to control our
inventory levels, and due to the modular architecture of our product line we are
able to easily reconfigure our products in order to respond to specific customer
purchase orders in a timely manner. Our business is generally not subject to any
cyclicality, but rather our customers place periodic purchase orders with us
based on their requirements for our products.

    Our systems include a number of components that come from sole source
suppliers such as Lucent, Motorola and Xilinx. Our contract manufacturers
procure these components from distributors or directly from the sole source
manufacturer. We do not have any contracts with these sole source suppliers, but
we communicate with them frequently in order to insure the continuing
availability of the components. Generally, if a manufacturer decides to
discontinue a critical component, it would provide enough time for us and our
contract manufacturers to locate alternative components. However, we might be
required to redesign our products or take other steps which could delay their
availability.

COMPETITION

    The GSM wireless market is rapidly evolving and highly competitive. We
believe that our business is affected by the following competitive factors:

    - conformity to industry standards;

    - breadth of product line;

    - implementation of additional product features and enhancements, including
      improvements in product performance, reliability, size and scalability;

    - cost;

    - ease of deployment;

    - sales and distribution capability; and

    - technical support and service.

    We expect that competition in each of our markets will increase in the
future. We currently compete against GSM communications equipment providers such
as Ericsson, Lucent, Motorola, Nokia, and Siemens. We also compete with the TDMA
and CDMA product offerings from these same communications equipment providers
and expect that a number of them will develop competing data communications
products and technologies in the near future. We also compete with the CDMA
product offerings of Samsung and LG. While Alcatel and Nortel Networks are our
customers, we do compete in several market applications. Most of these leading
GSM communications equipment providers focus on solutions that address large
numbers of subscribers. Equipment providers are beginning to focus on markets
with smaller subscriber bases as we do currently. All of the major GSM
communications equipment providers have at least partial GSM solutions that
address our target markets.

    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 seriously harm our business. We cannot assure
you that we will be able to compete successfully against current or future
competitors or that competitors will not preclude us from making or selling
certain products or that the competitive pressures we face will not seriously
harm our business and results of operations.

EMPLOYEES

    As of June 30, 2000, we employed or contracted 201 full-time people,
including 13 in operations, 56 in marketing, sales and customer support, 103 in
research and development and 29 in finance and administration. Of these
employees, 17 were contract employees who were primarily engaged in software
engineering and systems integration and testing. None of our employees is
represented by a labor union and we have experienced no work stoppages to date.
We believe our relationship with our employees is good.

GOVERNMENT REGULATION

    We must obtain regulatory approval for our products to be used in some
jurisdictions. Regulators in Europe, Asia and North America have approved our
products as being compliant with GSM standards. We may sell and deploy our
products in these jurisdictions and in other jurisdictions which rely on these
jurisdictions for approvals. In some cases, specific country compliance testing
may be required. The delays inherent in this regulatory approval process may
cause the rescheduling, postponement or cancellation of the installation of our
products by our customers, which in turn, may significantly reduce sales of
products to such customers.

    We are also subject to US government export controls. We rely on our
customers to inform us when they plan to deliver our products to other countries
and we regularly inform our customers of the export controls with which they
must comply.

ITEM 2. PROPERTIES

    Our corporate headquarters is located in Hamilton, Bermuda. Our principal
administrative and engineering facilities are located in leased facilities
totaling approximately 56,000 square feet in Menlo Park, California. The
five-year lease commenced December 15, 1999. We sublet our former premises in
Redwood City following our relocation in early calendar 2000, until the
expiration of our Redwood City lease in 2002. In addition, we lease sales,
service and systems testing facilities totaling approximately 5,900 square feet
in Hong Kong and approximately 3,500 square feet in Paris, France. The leases
for the Hong Kong facilities expire in 2001 and 2003 and the lease for the Paris
facility expires in 2005. We intend to lease additional facilities as our global
workforce increases. The subsidiaries we acquired after the end of the fiscal
year lease facilities in Ireland, England, China and San Diego, California. See
"Subsequent Events."

ITEM 3. LEGAL PROCEEDINGS

    On June 28, 1999, we filed a complaint against JetCell Corporation, which
was acquired by Cisco Systems in May 2000, in the United States District Court
for the Northern District of California (INTERWAVE COMMUNICATIONS
INTERNATIONAL LTD., V. CISCO SYSTEMS, INC.) alleging misappropriation of trade
secrets and infringement of United States Patent Nos. 5,734,979 and 5,818,824.
Two of the founders of JetCell Corporation are former employees of interWAVE.
The complaint seeks injunctive relief and damages. On July 19, 1999, JetCell
filed an answer to the complaint and a series of counterclaims against us. The
answer denied the allegations made in the complaint and the counterclaims
included allegations against us of unfair trade practices, unfair competition,
defamation, patent misuse and patent invalidity. The answer and counterclaims
seek injunctive relief, damages, invalidation of our patents and a dismissal of
the complaint. On August 9, 1999, we filed an answer to JetCell's counterclaims
denying the allegations made in the counterclaims. We are unable to predict the
outcome of the litigation and do not expect it to be resolved in the near
future. However, if we are unable to settle these proceedings in a satisfactory
manner, the legal proceedings may be time consuming and expensive and the
outcome could be adverse to us. If the outcome is adverse to us, we would
experience more competition in our markets and may be required to license
technology required for

                                       16
<PAGE>
our products, either of which could harm our business and financial results. An
adverse outcome could have a material adverse effect on our financial position.

    We may from time to time become a party to various legal proceedings arising
in the ordinary course of our business. However, other than as described above,
we are not currently involved in any material legal proceedings.

USE OF PROCEEDS FROM OUR INITIAL PUBLIC OFFERING

    On January 28, 2000, a registration statement on Form F-1 (No. 333-92967)
was declared effective by the SEC, pursuant to which 9,775,000 shares of our
common shares were offered and sold for our account at a price of $13.00 per
share, generating gross proceeds of approximately $127.1 million.

    In connection with the offering, we incurred $8.9 million in underwriting
discounts and commissions, and $1.9 million in other related expenses. The net
proceeds from the offering, after deducting the foregoing expenses, were
$116.3 million. Each outstanding share of preferred shares were automatically
converted into one share of common shares upon the closing of the initial public
offering. The managing underwriters were Salomon Smith Barney, Banc of America
Securities LLC and SG Cowen.

    As of September 25, 2000, we have not spent the net proceeds of the initial
public offering. We intend to use the net proceeds for general corporate
purposes, including working capital, expansion of our engineering organization,
product development programs, sales and marketing capabilities, general and
administrative functions and capital expenditures. We may also use a portion of
the net proceeds to invest in complementary products, to license other
technology or to make potential acquisitions.

OVERVIEW

    We provide compact wireless communications systems for the GSM market. We
were incorporated in June 1994 and recorded our first product sale in May 1997.
Our systems were initially deployed to add capacity and coverage to existing
systems, primarily in Asia. Deployments of community networks began in 1998,
primarily in China and Africa. Trials of our wireless office systems commenced
in 1999 in both Europe and Asia. Prior to May 1997, we had no sales and our
operations consisted primarily of various start-up activities, such as research
and development, recruiting personnel, conducting customer field trials and
raising capital. We generated net revenues of $13.0 million in 1998,
$17.3 million in 1999 and $30.1 million in 2000. We incurred net losses of
$30.8 million in 1998, $24.5 million in 1999 and $30.5 million in 2000. As of
June 30, 2000, we had an accumulated deficit of $140.2 million.

    We operate in a single business segment. We generate net revenues from sales
of our systems and, in connection with our direct sales activity, from
installation, maintenance contracts and support of those systems. Revenue
derived from systems sales, comprised of unit sales of our WAVEXpress base
station and base station controller, our WAVEXchange, our Network In A Box and
our WAVEView management system, constituted 92% of net revenues in 1998, 88% of
net revenues in 1999 and 96% of net revenues in 2000.

    Equipment revenue is recognized when all of the following have occurred: the
system has been shipped, title and risk of loss have passed to the customer, we
have the right to invoice the customer, collection of the receivable is probable
and we have fulfilled all contractual obligations to the customer. Revenue from
extended warranty coverage and customer support is recognized ratably over the
period of the service contract. Trial sales directly to wireless service
providers are not recognized as revenue until the trial is completed and title
and risk of loss has passed to the customer. Trials of our systems conducted by
communications equipment providers and systems integrators are typically shipped
from inventory held by those parties and do not result in incremental revenue to
us.

    Currently, our revenues are generated by sales to communications equipment
providers and system integrators that may either sell our systems on a
stand-alone basis or integrate them with their systems and by our direct sales
force. In fiscal year 2000, sales to communications equipment providers
represented 37% of total revenues, sales to systems integrators accounted for
40% of total revenues and direct sales to wireless service providers represented
23% of total revenues.

    We have entered into purchase and distribution original equipment
manufacturer (OEM) agreements with Nortel Networks and Alcatel. These multi-year
agreements specify quarterly minimum purchase commitments by these
communications equipment providers. Nortel Networks' quarterly purchase
commitments began in June 1998 and increase quarterly through December 2000.
Alcatel's quarterly purchase commitments commenced in June 2000 and extend
through December 2001. Both agreements also obligate us to meet certain product
development milestones and provide for a reduction in Nortel Networks' and
Alcatel's purchase commitments if we do not meet our development milestones. In
April 1999, we agreed to reduce Nortel Networks' remaining quarterly commitments
because we were unable to meet certain product feature specifications provided
for in the agreement. We do not rely solely on these purchase commitments to
forecast our production requirements or anticipated sales to these customers.
Rather, we also rely on our internal sales forecasts and our ongoing discussions
with these customers, including their formal purchase orders, as guidance for
planning our production and our revenue outlook. However, we do rely in part on
these minimum purchase commitments in forecasting production quantities. Because
of the relatively fixed nature of many of our expenses, including personnel and
facilities costs, we cannot immediately adjust expenses in response to a decline
in revenues. Therefore, failure of these customers to achieve their quarterly
purchase commitments could cause a decline in our operating results.

    Net revenues outside the United States represented approximately, 53%, 80%
and 88% of total net revenues in fiscal years 1998, 1999 and 2000, respectively.
We have derived and expect to continue

                                       21
<PAGE>
to derive a majority of our revenues from products installed outside the U.S. by
both non-U.S. and U.S. based communications equipment providers, systems
integrators and wireless service providers, subjecting our revenue stream to
risks from economic uncertainties, currency fluctuations, political instability
and uncertain cultural and regulatory environments. All of our revenues are
currently in U.S. dollars, which reduces our exposure to fluctuations in
revenues attributable to changes in currency exchange rates. In the future,
business conditions may require us to sell our products in other currencies. In
addition, we face risks inherent in conducting global business. These risks
include extended collection time for receivables, the potential loss of security
interest, reduced ability to enforce obligations and reduced protection for our
intellectual property.

    We have a limited history of generating significant revenues, and many of
our products have only recently been introduced. We have incurred substantial
operating losses since our inception and we expect to incur net losses in the
future, which may be substantial. Most of our expenses are fixed in the near
term, and we may not be able to quickly reduce spending if our revenue is lower
than anticipated. Therefore, net losses in a given quarter could be greater than
expected. You have limited historical financial data and operating results with
which to evaluate our business and our prospects. As a result, you must consider
our prospects in light of the early stage of our business in a new and rapidly
evolving market. For additional information on factors that may affect our
future results of operations, please see "Factors That May Affect Future
Results."

    Communications equipment providers, system integrators and wireless service
providers typically perform numerous tests and extensively evaluate products
before incorporating them into their networks. The time required for testing,
evaluation and design of our systems into the service provider's network
typically ranges from six to twelve months. During the trial period we sell a
limited number of units. The successful completion of the trial phase often
results in another sale of additional units intended for deployment in
commercial service. 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 systems.

    Cost of revenues consists of material costs, direct labor costs, warranty
costs, royalties, overhead related to manufacturing our products, amortization
of intangible assets, and customer support costs.

    In general, our gross margins will be affected by the following factors and,
therefore, we are unable to predict what these margins will be in the future:

    - demand for our products and services;

    - new product introductions, both by us and our competitors;

    - changes in our pricing policies and those of our competitors;

    - the mix of products sold;

    - the sales channels through which our products are sold; and

    - the purchase volume discounts we are able to obtain from our contract
      manufacturers.

    We currently obtain all of our primary components and subassemblies for our
products from a single independent contract manufacturer. Accordingly, a
significant portion of our cost of revenues consists of payments to this
supplier. The remainder of our cost of revenues is related to our in-house
manufacturing operations, which consist primarily of quality control, final
assembly, testing and product integration.

    Research and development expenses consist primarily of compensation and
related costs for research and development personnel and expenses for testing
facilities and equipment. All research and development costs are expensed as
they are incurred. We expect to continue to make substantial

                                       22
<PAGE>
investments in research and development and anticipate that these expenses will
continue to increase in absolute dollars.

    Selling, general and administrative expenses consist primarily of
compensation and related costs for sales and sales support personnel, marketing
personnel, financial, accounting, human resource and general management
personnel, sales commissions, marketing programs, legal and professional
services, travel expenses, bad debt expenses and other general corporate
expenses. We expect to incur substantial expenditures related to sales and
marketing activities, the recruitment of additional sales and marketing
personnel and the expansion of our domestic and international distribution
channels. We expect selling, general and administrative expenses to increase in
absolute dollars due to the addition of sales and marketing personnel and due to
the additional costs related to the anticipated growth of our business and
operation as a public company.

    Since our inception, we have used share option programs for key employees as
compensation to attract strong business and technical talent. We have recorded
compensation expense for our option grants. The expense is equal to the excess
of the fair market price on the date of grant or sale over the option exercise
price. Of the total deferred compensation, approximately $7.6 million,
$5.3 million and $9.9 million was amortized in fiscal years 1998, 1999 and 2000,
respectively. The balance in deferred compensation of $6.2 million at June 30,
2000 is being amortized on an accelerated basis over the vesting period of the
applicable options, which is typically four years.

    Our current products operate on the GSM standard. GSM competes with other
digital standards, including code division multiple access, or CDMA, and time
division multiple access, or TDMA. GSM also competes with analog standards. In
the event that TDMA or CDMA become the dominant digital wireless communication
standard in geographic markets we are seeking to address, the acceptance of our
products and our revenues and operating results would be harmed.

    Our industry is intensely competitive, and many of our competitors are major
telecommunications equipment providers with resources that are significantly
greater than ours. In addition to competitive pressures, we will also likely
encounter declining sales prices and profit margins over time as products
mature.

</TABLE>

    The percentage of net revenues on a fiscal year basis comprised of sales to
Nortel Networks may decline due in part to the broadening of our customer base.
Nortel Networks is a principal shareholder of ours. ADC Telecommunications,
Alcatel and Holodeck Limited, an affiliate of Hutchison Telecommunications Group
and a wholly-owned subsidiary of Hutchison Whampoa, are shareholders of ours.
Microcellular Systems was created by a spin-off from ADC Telecommunications. Due
in part to general improvements in economic conditions in several key Asian
markets, we may experience increased sales in Asia in future periods.

    We have started negotiations for a purchase/resale agreement with Intasys
Corporation, one of our shareholders. Intasys plans to market our products in
Canada. As of June 30, 2000, we had recorded $3.6 million in services receivable
from this shareholder as a result of our issuance to Intasys of a warrant to
purchase 615,000 common shares at $1.00 per share. This warrant was exercised by
Intasys

                                       24
<PAGE>
in January 2000 prior to our initial public offering. See Note 9 to the
Consolidated Financial Statements.

COMPARISON OF FISCAL YEARS ENDED JUNE 30, 1999 AND 2000

NET REVENUES

    Net revenues increased 74%, an increase of $12.8 million, from
$17.3 million for the fiscal year ended June 30, 1999 to $30.1 million for the
fiscal year ended June 30, 2000. This increase was due to continued increases in
the number of active customers and the continued deployment of our systems.
Twelve customers accounted for all of our net revenues in 1999 while 22
customers accounted for all of our net revenues in 2000. Sales to Nortel
Networks and ADC Telecommunications accounted for 51% and 20%, respectively, of
net revenues in 1999, while sales to Nortel Networks, affiliates of Hutchison
Telecommunications Group, and HangZhou Topper Electric Corporation accounted for
28%, 21% and 11%, respectively, of net revenues in 2000.

COST OF REVENUES

    Cost of net revenues increased 50%, an increase of $6.2 million, from
$12.5 million during 1999 compared with $18.7 million during 2000. As a
percentage of net revenues, cost of revenues decreased from 72% in 1999 to 62%
in 2000, due to the overall volume of sales, offset in part by changes in the
mix of products sold. In 1999, 35% of net revenues was attributed to our
WAVEXchange and Network In A Box products, which earn higher gross profits,
while 45% was attributed to our WAVEXpress/ BTS, which earns lower gross
profits. In 2000, 22% of net revenues was attributed to our WAVEXchange and
Network In A Box products, which earn higher gross profits, while 64% was
attributed to our WAVEXpress/BTS, which earns lower gross profits. The product
mix in any period will vary depending on the customer's application and network
design, and therefore our gross profits will fluctuate. Due to the relatively
short time that we have been shipping our complete product line, we are unable
to forecast with certainty our product mix on a quarterly basis. As a result, we
expect that our gross profits will fluctuate on a quarterly basis.

RESEARCH AND DEVELOPMENT EXPENSES

    Research and development expenses increased by $3.9 million, an increase of
28%, from $14.2 million in 1999 to $18.1 million in 2000. The increase was
primarily due to increased headcount in research and development from 75 at
June 30, 1999 to 103 at June 30, 2000. Increased expenses can also be attributed
to higher depreciation expenses associated with purchased equipment and
intangible assets, and to higher facility expenses in the second half of fiscal
2000.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses increased by $6.1 million, an
increase of 82%, from $7.4 million during 1999 compared to $13.5 million in
2000. The increase was partially due to $2.4 million higher salaries and related
labor costs associated with increased headcount in sales, marketing, finance and
administration, $0.7 million higher legal and professional services expenses, a
$0.8 million addition to our allowance for doubtful accounts, and $0.7 million
of amortization expenses ascribed to warrants granted in September 1999 to a
potential distributor. Increased facilities expenses of $1.3 million in
connection with the move of our main facilities and increased travel expenses of
$.5 million, also contributed to the overall rise in expenses. Selling, general
and administrative expenses are expected to continue to increase as we expand
our marketing and sales support staff to support the increased number of
customers we serve and as we increase our general, administrative and management
expenses to provide support as a public company.

AMORTIZATION OF DEFERRED STOCK COMPENSATION

    Amortization of deferred stock compensation increased $4.6 million, an
increase of 88%, from $5.3 million in 1999 compared to $9.9 million in 2000.
During 2000, options to purchase 3.86 million common shares were granted at an
average exercise price of $5.46 resulting in an addition to deferred stock
compensation of $12.4 million.

INTEREST INCOME

    Interest income increased $3.9 million from $0.2 million in 1999 to
$4.1 million in 2000. The increase was due to the yield on investments as a
result of our initial public offering, which was completed in January 2000.

INTEREST EXPENSE

    Interest expense was $2.4 million versus $2.1 million in 1999 and 2000,
respectively. This expense was principally due to amortization of the discount
ascribed to the warrants issued in conjunction with the 1999 bridge loan
financing. See Note 8 to the Consolidated Financial Statements. The notes were
converted to Series H1 preferred shares on September 10, 1999. As a result of
the conversion of the notes into Series H1 preferred shares in September, the
unamortized discount was converted to additional paid-in-capital, and no further
interest expense will be incurred relative to the bridge loan financing.

    The Company has a committed $5 million line of credit. Should we elect to
borrow funds under our committed line of credit, we will incur interest expense
during any periods when amounts are outstanding under the line. At current
interest rates, the $5 million borrowings provision under the available line
would result in annual interest expense of approximately $444,000. There are no
current plans to draw down any of the available funds under this revolving line
of credit.

INCOME TAXES

    There is no income tax on income earned in Bermuda.

    In 1998, 1999 and 2000 our U.S. subsidiary incurred net losses for United
States federal and state income tax purposes; and we recorded a provision for
income taxes of $220,000, $113,000 and $99,000, respectively, related to current
international income tax provided on the profits attributable to our foreign
operations. As of June 30, 2000, we had $61 million of federal and $32 million
of state net operating loss carryforwards to offset future taxable income. The
difference between available net operating losses and our accumulated deficit as
reported for financial statement purposes is principally because losses incurred
in Bermuda are not subject to a carry-forward since there is no tax on income
earned in Bermuda, and the losses attributable to our U.S. subsidiary relate to
the manufacturing and development operations of our U.S. subsidiary and not to
our global sales and marketing activity.

COMPARISON OF FISCAL YEARS ENDED JUNE 30, 1998 AND 1999

NET REVENUES

    Net revenues increased $4.3 million or 33%, from $13.0 million in 1998 to
$17.3 million in 1999. This increase was principally due to increased sales to
Nortel Networks, who began marketing our products in the fourth quarter of 1998.
Nortel Networks accounted for $8.8 million of our 1999 net revenues, an increase
of $6.4 million over 1998. This increase, however, was offset by a reduction in
sales, through ADC Telecommunications who, with our consent, assigned our
distribution agreement to Microcellular Systems, a new company formed by a group
of former ADC Telecommunications employees in the spring of 1999. ADC
Telecommunications accounted for $3.4 million of our sales in 1999 and
$6.1 million in 1998. Also, in the second half of fiscal 1998, wireless service
providers in Asia

                                       26
<PAGE>
were adversely impacted by local economic conditions and accordingly curtailed
their planned programs to deploy our products aggressively in their networks.
Thus, sales to Hutchison Telecommunications Group and Total Access
Communications each declined to less than 10% of our revenues in fiscal 1999.
Net revenues in 1999 included $1.0 million related to training and support
services provided to a communications equipment provider. We incurred
$0.2 million of expenses related to this net revenue.

COST OF REVENUES

    Cost of revenues increased $0.2 million from $12.3 million in 1998 to
$12.5 million in 1999. As a percentage of net revenues, cost of revenues
decreased from 94% in 1998 to 72% in 1999. The decrease in the percentage of net
revenues was primarily due to lower cost of revenues associated with the
WAVEXchange and Network In A Box products introduced in the first half of fiscal
1999.

RESEARCH AND DEVELOPMENT EXPENSES

    Research and development expenses decreased $1.1 million or 7% from
$15.3 million in 1998 to $14.2 million in 1999 primarily due to a reduction in
nonrecurring engineering costs and engineering contractor expenses of
$1.2 million. In addition, expenses were reduced $0.3 million for hiring and
relocation expense, and $0.5 million for prototype materials. These reductions
were offset with other expense increases including additional personnel costs of
$0.4 million, increased depreciation expense of $0.2 million and intangible
amortization of $0.3 million.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses declined $0.3 million from
$7.7 million in 1998 to $7.4 million in 1999. This decrease was due to a shift
in our sales strategy to emphasize indirect sales channels. Selling general and
administrative expenses began increasing in the fourth quarter of 1999 as we
began making investments in marketing programs and increasing our presence in
Hong Kong and Paris.

AMORTIZATION OF DEFERRED STOCK COMPENSATION

    Amortization of deferred stock compensation decreased $2.3 million from
$7.6 million in 1998 to $5.3 million in 1999.

</TABLE>

    OPERATING ACTIVITIES.  Net cash used in operating activities in 2000, 1999
and 1998 was primarily a result of net operating losses.

    INVESTING ACTIVITIES.  Our recent investing activities have consisted
primarily of purchases of $92.2 million in short-term investments arising from
the funds received from the initial public offering. Other uses of cash in
investing activities consisted of purchases of $5.1 million in capital equipment
and intangible assets. We expect that capital expenditures will increase due to
continued expansion of our operations, our increasing employee base, and our
continued investment in research and development.

    FINANCING ACTIVITIES.  In January 2000, we completed our initial public
offering, which raised $116.3 million net of costs. In November and December
1999 we sold 4.9 million preferred shares for aggregate proceeds of
$37.9 million, net of costs.

    In 1999 and 1998, we had funded our operations primarily through private
placement of bridge loans and convertible preferred shares.

    COMMITMENTS.  We lease all of our facilities under operating leases that
expire at various dates through 2005. As of June 30, 2000, we had $12.5 million
in future operating lease commitments and $0.5 million of equipment financing.
In the future we expect to continue to finance the acquisition of computer and
network equipment through additional equipment financing arrangements.

    SUMMARY OF LIQUIDITY.  We believe that the existing cash, cash equivalents
and short-term investments, in addition to funds available under committed
credit facilities, will be sufficient to meet our working capital requirements
for the foreseeable future. However, the risk factors discussed in item 7 could
adversely affect our cash position. We may require additional funds to support
our working capital requirements or for other purposes and may seek to raise
these additional funds through public or private debt or equity financing or
from other sources.

EFFECT OF RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivatives and Hedging
Activities" ("SFAS 133"), which establishes accounting and reporting standards
for derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as "derivatives") and for hedging
activities. SFAS 133, as amended by SFAS 137 and SFAS 138, is effective for all
fiscal quarters of fiscal years beginning after June 15, 2000. As the Company
does not currently engage in derivatives or hedging transactions, there would be
no current impact to our results of operations, financial position, or cash
flows upon the adoption of SFAS 133.

    In December 1999, the Securities and Exchange Commission ("SEC") released
Staff Accounting Bulletin ("SAB") No. 101 "REVENUE RECOGNITION IN FINANCIAL
STATEMENTS," as amended by SAB No. 101B, which provides guidance on the
recognition, presentation, and disclosure of revenue in financial statements
filed with the SEC. SAB No. 101 outlines the basic criteria that must be met to
recognize revenue and provides guidance for disclosures related to revenue
recognition policies. We expect to adopt SAB No. 101 by the fourth quarter of
fiscal 2001. Although we do not expect the

                                       28
<PAGE>
adoption of SAB No. 101 to have a material effect on our financial statements,
implementation guidance is expected to be released by the SEC in the near term.

    In March 2000, the FASB issued Interpretation No. 44 "ACCOUNTING FOR CERTAIN
TRANSACTIONS INVOLVING STOCK COMPENSATION, AN INTERPRETATION OF APB OPINION
NO. 25." This interpretation clarifies the application of Opinion 25 for certain
issues including: (a) the definition of employee for purposes of applying
Opinion 25, (b) the criteria for determining whether a plan qualifies as a
non-compensatory plan, (c) the accounting consequence of various modifications
to the terms of a previously fixed stock option or warrant, and (d) the
accounting for an exchange of stock compensation awards in a business
combination. In general, the interpretation is effective July 1, 2000. The
adoption of Interpretation No. 44 did not have a material effect on our
financial statements.

FACTORS THAT MAY AFFECT FUTURE RESULTS

    In addition to the information in this Annual Report on Form 10-K, the
following should be considered in evaluating interWAVE and our business.

INVESTING IN OUR COMMON SHARES INVOLVES A HIGH DEGREE OF RISK. IF ANY OF THE
FOLLOWING RISKS OCCUR, THE MARKET PRICE OF OUR COMMON SHARES COULD DECLINE AND
YOU COULD LOSE ALL OR PART OF YOUR INVESTMENT.

BECAUSE WE HAVE A LIMITED OPERATING HISTORY, WE CANNOT BE SURE THAT WE CAN
SUCCESSFULLY EXECUTE OUR BUSINESS STRATEGY.

    We did not record revenue from our first product sale until May 1997. We
have a limited history of generating significant revenues. Many of our products
have only recently been introduced and many of our customers are testing our
products for incorporation into live networks. Therefore, you have limited
historical financial data and operating results with which to evaluate our
business and our prospects. You must consider our prospects in light of the
early stage of our business in a new and rapidly evolving market. Our limited
operating history may make it difficult for you to assess, based on historical
information, whether we can successfully execute our business strategy. If we
are unable to successfully execute our business strategy, we would likely not
achieve anticipated levels of revenue growth. In this event, we would be unable
to achieve profitability or build a sustainable business.

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

    As of June 30, 2000, we had an accumulated deficit of $140.2 million. We
incurred net losses of approximately $30.8 million, $24.5 million and
$30.5 million in the fiscal years ended June 30, 1998 and 1999 and 2000,
respectively. We expect to continue to incur net losses and these losses may be
substantial. Furthermore, we expect to generate significant negative cash flow
in the future. We will need to generate substantially higher revenues to achieve
and sustain profitability and positive cash flow. Our ability to generate future
revenues and achieve profitability will depend on a number of factors, many of
which are beyond our control. These factors include:

    - the rate of market acceptance of compact mobile wireless systems;

    - our ability to compete successfully against much larger GSM communications
      equipment providers; and

    - our ability to continue to expand our customer base.

    Due to these factors, as well as other factors described in this risk
factors section, we may be unable to achieve or maintain profitability. If we
are unable to achieve or maintain profitability, we will be unable to build a
sustainable business. In this event, our share price and the value of your
investment would likely decline.

                                       29
<PAGE>
OUR QUARTERLY OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY AND MAY
FAIL TO MEET THE EXPECTATIONS OF SECURITIES ANALYSTS AND INVESTORS, WHICH MAY
CAUSE OUR SHARE PRICE TO DECLINE.

    Our quarterly operating results have fluctuated significantly in the past
and are likely to do so in the future. If our operating results do not meet the
expectations of securities analysts and investors, our share price is likely to
decline. The many factors that could cause our quarterly results to fluctuate
include:

    - any delay in our introduction of new products or product enhancements;

    - the size and timing of customer orders and our product shipments, which
      have typically consisted of a relatively small number of units of wireless
      network systems at the end of each quarter;

    - the mix of products sold because our various products generate different
      gross margins;

    - any delay in shipments caused by component shortages or other
      manufacturing problems, extended product testing or regulatory issues;

    - the timing of orders from and shipments to major customers, including
      possible cancellation of orders and failure of major customers to meet
      applicable minimum purchase commitments;

    - the loss of a major customer;

    - reductions in the selling prices of our products;

    - cost pressures from shortages of skilled technical employees, increased
      product development and engineering expenditures and other factors; and

    - customer responses to announcements of new products and product
      enhancements by competitors and the entry of new competitors into our
      market.

    Due to these and other factors, our results of operations could fluctuate
substantially in the future, and quarterly comparisons may not be reliable
indicators of future performance. In addition, because many of our expenses for
personnel, facilities and equipment are relatively fixed in nature, if revenues
fail to meet our expectations, we may not be able to reduce expenses
correspondingly. As a result, we would experience greater than expected net
losses. If we experience greater than expected net losses, our share price and
the value of your investment would likely decline.

WE RELY ON A SMALL NUMBER OF CUSTOMERS FOR MOST OF OUR REVENUES, AND A DECREASE
IN REVENUES FROM THESE CUSTOMERS COULD SERIOUSLY HARM OUR BUSINESS.

    A small number of customers have accounted for a significant portion of our
revenues to date. Net revenues from significant customers as a percentage of our
total net revenues in the three most recent fiscal years were as follows:

</TABLE>

    Nortel Networks is one of our principal shareholders, and a Nortel Networks
employee is a member of our board of directors. ADC Telecommunications is a
shareholder of ours. In addition, the parent corporation of Total Access
Communications and ADC Telecommunications are shareholders of

                                       30
<PAGE>
ours. Microcellular Systems, Ltd. was created by a spin-off from ADC
Telecommunications in May 1999, and was acquired by interWAVE in July 2000. See
"Subsequent Events."

    We expect that the majority of our revenues will continue to depend on sales
to a small number of customers. If any key customers experience a downturn in
their business or shift their purchases to our competitors, our revenues and
operating results would decline.

    If our revenues, including those expected from Nortel Networks and Alcatel
under our purchase and distribution agreements, are lower than expected, we may
not be able to quickly reduce expenses because many of our expenses are fixed in
the near term.

WE HAVE MINIMUM PURCHASE COMMITMENTS FROM NORTEL NETWORKS AND ALCATEL, AND IF
THEY FAIL TO MEET THESE COMMITMENTS, THIS FAILURE COULD HARM OUR BUSINESS AND
OPERATING RESULTS.

    Nortel Networks and Alcatel have minimum purchase commitments under their
respective agreements. We rely in part on these commitments in forecasting
production quantities each quarter. We have also committed to Nortel Networks
and Alcatel that we will maintain quality, delivery, performance and design
standards for our systems. As a result, we bear the risk of carrying excess
inventory if Nortel Networks and Alcatel fail to meet their commitments or if we
fail to meet ours. From time to time, we have failed to deliver certain product
features by specific milestone dates and, as a result, we have renegotiated
downward minimum quarterly commitments with Nortel Networks. Nortel Networks did
not meet the renegotiated commitments for three of the four quarters ended
June 30, 2000. We cannot assure you that future minimum commitments will be met
or that they will not be renegotiated downward in the future. Failure of Nortel
Networks or Alcatel to meet minimum purchase commitments could cause our
revenues and operating results to decline. Furthermore, because Nortel Networks'
commitments are larger than Alcatel's, Nortel Networks' failure to meet
commitments would harm our operating results to a greater extent than Alcatel's
failure to do so. Failure of these companies to meet these commitments could
also cause our stock price to decline as a result of a revenue shortfall or
greater than anticipated operating losses.

WE CURRENTLY DEPEND ON A SINGLE CONTRACT MANUFACTURER FOR MOST OF OUR PRODUCTS
AND PLAN TO USE ONLY A SINGLE CONTRACT MANUFACTURER IN THE FUTURE.

    We depend on one contract manufacturer for most of our products. We do not
have long-term supply contracts with our contract manufacturers, and they are
not obligated to supply us with products for any specific period, in any
specific quantity or at any specific price, except as may be provided in a
particular purchase order. None of our products are manufactured by more than
one supplier, and we do not expect this to change for the foreseeable future.

    There are risks associated with our dependence on contract manufacturers,
including the contract manufacturer's control of capacity allocation, labor
relations, production quality and other aspects of the manufacturing process. If
we are unable to obtain our products from manufacturers on schedule, revenues
from the sale of those products may be delayed or lost, and our reputation,
relationship with customers and our business could be harmed. In addition, in
the event that a contract manufacturer must be replaced, the disruption to our
business and the expense associated with obtaining and qualifying a new contract
manufacturer could be substantial. If problems with our contract manufacturers
cause us to miss customer delivery schedules or result in unforeseen product
quality problems, we may lose customers. As a result, our revenues and our
future growth prospects would likely decline.

                                       31
<PAGE>
BECAUSE SOME OF OUR KEY COMPONENTS COME FROM A SINGLE SOURCE, OR REQUIRE LONG
LEAD TIMES, WE COULD EXPERIENCE UNEXPECTED INTERRUPTIONS WHICH COULD CAUSE OUR
OPERATING RESULTS TO SUFFER.

    We believe that a number of our suppliers are sole sources for key
components. These key components are complex and difficult to manufacture and
require long lead times. 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 other suppliers. Supply
interruptions could delay product shipments, causing our revenues and operating
results to decline.

WE DO NOT TYPICALLY HAVE A SALES BACKLOG AND THEREFORE MAY INCUR EXPENSES FOR
EXCESS INVENTORY OR BE UNABLE TO MEET CUSTOMER REQUIREMENTS.

    We do not have a significant backlog because our customers typically give us
firm purchase orders with short lead times before requested shipment. However,
our contract manufacturers require commitments from us so that they can allocate
capacity and be assured of having adequate components and supplies from third
parties. Failure by us to accurately estimate product demand could cause us to
incur expenses related to excess inventory or prohibit us from meeting customer
requirements.

OUR PRODUCTS ARE COMPLEX AND MAY HAVE ERRORS OR DEFECTS THAT ARE DETECTED ONLY
AFTER DEPLOYMENT IN COMPLEX NETWORKS, WHICH MAY HARM OUR BUSINESS.

    Our products are highly complex and are designed to be deployed in complex
networks. Although our products are tested during manufacturing and prior to
deployment, they can only be fully tested when deployed in networks with
high-call volume. Consequently, our customers may discover errors after the
products have been fully deployed. If we are unable to fix errors or other
problems that may be identified in full deployment, we could experience:

    - costs associated with the remediation of any problems;

    - loss of or delay in revenues;

    - loss of customers;

    - failure to achieve market acceptance and loss of market share;

    - diversion of deployment resources;

    - increased service and warranty costs;

    - legal actions by our customers; and

    - increased insurance costs.

    In addition, our products often are integrated with other network
components. There may be incompatibilities between these components and our
products that could significantly harm the service provider or its subscribers.
Product problems in the field could require us to incur costs to remedy the
problems and subject us to liability for damages caused by the problems. These
problems could also harm our reputation and competitive position in the
industry.

WE MAY EXPERIENCE DIFFICULTIES IN THE INTRODUCTION OF NEW OR ENHANCED PRODUCTS
THAT COULD RESULT IN SIGNIFICANT, UNEXPECTED EXPENSES OR DELAY THEIR LAUNCH,
WHICH WOULD HARM OUR BUSINESS.

    The development of new or enhanced products is a complex and uncertain
process. We may experience design, manufacturing, marketing and other
difficulties that could delay or prevent our development, introduction or
marketing of new products or product enhancements. We must also effectively
manage the transition from old products to new or enhanced products. We are
currently developing a system providing voice communication over the Internet.
We cannot assure you that we

                                       32
<PAGE>
will be able to develop, introduce or manage this or any other new products or
product enhancements in a timely manner or at all. Failure to develop new
products or product enhancements in a timely manner would substantially decrease
market acceptance and sales of our products.

FAILURE TO COMPLY WITH REGULATIONS AFFECTING THE TELECOMMUNICATIONS INDUSTRY
COULD SERIOUSLY HARM OUR BUSINESS AND RESULTS OF OPERATIONS.

    Our failure to comply with government regulations relating to the
telecommunications industry in countries where our products are deployed and
failure to comply with any changes to those regulations could seriously harm our
business and results of operations. We have not completed all activities
necessary to comply with existing regulations and requirements in some of the
countries in which we intend to sell our products. Compliance with the
regulations of numerous countries could be costly and require delays in
deployments.

OUR FAILURE TO COMPLY WITH EVOLVING INDUSTRY STANDARDS COULD DELAY OUR
  INTRODUCTION OF NEW PRODUCTS.

    An international consortium of standards bodies is working to establish the
specifications of a future wireless standard and its interoperability with
existing standards. Any failure of our products to comply could delay their
introduction and require costly and time consuming engineering changes. After
the future standard is adopted, any delays in our introduction of next
generation products could impair our ability to grow revenues in the future. As
a result, we may be unable to achieve or sustain profitability.

OUR MARKET OPPORTUNITY COULD BE SIGNIFICANTLY DIMINISHED IN THE EVENT THAT GSM
OR ANY SUBSEQUENT GSM-BASED STANDARDS DO NOT CONTINUE TO BE OR ARE NOT WIDELY
ADOPTED.

    Our current products are designed to utilize GSM, an international standard
for voice and data communications. There are other competing standards including
code division multiple access, or CDMA, and time division mutiple access, or
TDMA. We currently do not have plans to offer products that utilize these
standards. In the event that GSM or any GSM-based standards do not continue to
be or are not broadly adopted, our market opportunity could be significantly
limited, which would seriously harm our business.

WE HAVE A LONG SALES CYCLE, WHICH COULD CONTRIBUTE TO FLUCTUATIONS IN OUR
  RESULTS OF OPERATIONS AND SHARE PRICE.

    Our sales cycle is typically long and unpredictable, making it difficult to
plan our business. The long sales cycle also requires us to invest resources in
a possible transaction that may not be recovered if we do not successfully
conclude the transaction. Factors that affect the length of our sales cycle
include:

    - time required for testing and evaluation of our products before they are
      deployed in a network;

    - size of the deployment;

    - complexity of the customer's network environment; and

    - the degree of system configuration necessary to deploy our products.

    In addition, the emerging and evolving nature of the market for the systems
we sell may lead prospective customers to postpone their purchasing decisions.
Our long and unpredictable sales cycle can result in delayed revenues,
difficulty in matching revenues with expenses and increased expenditures, which
together may contribute to declines in our results of operations and our share
price.

                                       33
<PAGE>
INTENSE COMPETITION IN THE WIRELESS MARKET COULD PREVENT US FROM INCREASING OR
SUSTAINING REVENUES OR ACHIEVING OR SUSTAINING PROFITABILITY.

    The wireless market is rapidly evolving and highly competitive. We cannot
assure you that we will have the financial resources, technical expertise or
marketing, manufacturing, distribution and support capabilities to compete
successfully in the future. We expect that competition in each of our markets
will increase in the future.

    In the wireless office network market, the primary competing standard for
our systems is the digital European cordless telephone standard known as DECT.
In the community network market, we compete against wireless local loop
networks, which are wireless communication systems that connect users to the
public telephone network using radio signals as a substitute for traditional
telephone connections.

    We currently compete against communications equipment providers such as
Ericsson, Lucent, Motorola, Nokia and Siemens in the GSM, CDMA, TDMA, DECT and
wireless local loop markets. We also compete with our customers Alcatel and
Nortel Networks. All of the major communications equipment providers have broad
product lines that include at least partial solutions that address our target
markets.

    In addition, we are seeking to sell our products in emerging markets, many
of which have less reliable traditional telephone infrastructures than developed
countries. If these countries improve the reliability and service of their
traditional telephone networks, the demand for our products in these markets
could be harmed and our future revenue growth could decline.

    Many of our competitors and potential competitors have substantially greater
name recognition and technical, financial and sales and marketing resources than
we have. Such competitors may undertake more extensive marketing campaigns,
adopt more aggressive pricing policies and devote substantially more resources
to developing new products than we can. Trends toward increased consolidation in
the telecommunications industry may increase the size and resources of some of
our current competitors and could affect some of our current relationships.

    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 seriously harm our business. We cannot assure
you that we will be able to compete successfully against current or future
competitors. Competitive pressures we face may cause our revenues or growth to
decline and may therefore seriously harm our business and results of operations.

IF WE ARE UNABLE TO MANAGE OUR GLOBAL OPERATIONS EFFECTIVELY, OUR BUSINESS WOULD
BE SERIOUSLY HARMED.

    Substantially all of our revenue to date has been derived from systems
intended for installation outside of the United States. In addition to the
regulatory issues discussed previously, our operations are subject to the
following risks and uncertainties:

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

    - greater difficulty in trades receivable collection and longer collection
      periods;

    - costs of staffing and managing operations in several countries;

    - difficulties in protecting intellectual property rights;

    - changes in currency exchange rates which may make our U.S.
      dollar-denominated products less competitive in global markets;

    - the impact of recessions in global economies; and

    - political and economic instability.

                                       34

    In our joint venture with Hangzhou Topper Electric we expect to establish
manufacturing operations in China during calendar year 2000 which may subject
our joint venture to all of the risks listed above, particularly the difficulty
of protecting intellectual property rights.

WE HAVE EXPERIENCED AN INCREASE IN SALES TO COMPANIES IN THE PEOPLES REPUBLIC OF
CHINA, AND FUTURE SALES IN CHINA WILL BE SUBJECT TO ECONOMIC AND POLITICAL
RISKS.

    In the year ended June 30, 2000, sales to five customers, all located in the
Peoples Republic of China, accounted for 24% of our revenues. Sales in China
pose significant additional risks, which include:

    - potential inability to enforce contracts or take other legal action,
      including actions to protect intellectual property rights;

    - difficulty in collecting revenues and risks related to fluctuations in
      currency exchange rates, particularly when sales are denominated in the
      local currency rather than in U.S. dollars;

    - changes in U.S. foreign trade policy towards China which may restrict our
      ability to export products to or make sales in China, and similar changes
      in China's policy regarding the U.S.; and

    - changes in government regulation affecting companies doing business in
      China, either through export sales or local manufacturing operations.

    In the event our revenue levels from sales to China increase, we will become
increasingly subject to these risks. The occurrence of any of these risks would
harm our revenues from China and could in turn cause our revenues or growth to
decline and harm our business and results of operations.

IF WE FAIL TO IMPROVE OUR OPERATIONAL SYSTEMS AND CONTROLS TO MANAGE FUTURE
GROWTH, OUR BUSINESS COULD BE SERIOUSLY HARMED.

    We plan to continue to expand our operations significantly to pursue
existing and potential market opportunities. This growth places significant
demands on our management and our operational resources. In order to manage
growth effectively, we must implement and improve our operational systems,
procedures and controls on a timely basis.

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

    Our business is highly dependent on our ability to attract, retain and
motivate qualified technical and management personnel. Competition is intense
for qualified personnel in our industry and in Northern California, where most
of our engineering personnel are located, and we may not be successful in
attracting and retaining these personnel. We do not have non-compete agreements
with any of our key employees. We currently do not maintain key person life
insurance on any of our key executives. Our success also depends upon the
continuing contributions of our key management and our research, product
development, sales and marketing and manufacturing personnel. Many of these
would be difficult to replace.

OUR INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS MAY BE INSUFFICIENT TO PROTECT
OUR COMPETITIVE POSITION.

    We cannot assure you that the protection offered by our U.S. patents will be
sufficient or that any of our pending U.S. or foreign patent applications will
result in the issuance of patents. In addition, competitors in the United States
and other countries, many of whom have substantially greater resources, may
apply for and obtain patents that will prevent or interfere with our ability to
make and

                                       35
<PAGE>
sell our products in the U.S. and/or abroad. Unauthorized parties may attempt to
design around our patents, copy or otherwise obtain and use our products. We
cannot be certain that the steps we have taken will prevent unauthorized use of
our technology, particularly in countries where the laws may not protect our
proprietary rights as fully as in the United States. Failure to protect our
proprietary rights could harm our competitive position and therefore cause our
revenues and operating results to decline.

    On June 28, 1999, we filed a complaint against JetCell Corporation in the
United States District Court for the Northern District of California alleging
misappropriation of trade secrets and patent infringement. JetCell has filed a
series of counterclaims against us, which include allegations of unfair trade
practices, unfair competition, defamation, patent misuse and patent invalidity.
In May 2000 JetCell was acquired by Cisco Systems, Inc. Cisco has been
substituted as the defendant. We are unable to predict the outcome of this
litigation and do not expect it to be resolved in the near future. The legal
proceedings may be distracting to our management and expensive and the outcome
could be adverse to us. An adverse outcome could have a material adverse effect
on our financial position. If the outcome is adverse to us, we could experience
more competition or could be required to license our technology, either of which
could harm our business and financial results. See "Legal Proceedings."

CLAIMS THAT WE INFRINGE THIRD-PARTY INTELLECTUAL PROPERTY RIGHTS COULD RESULT IN
SIGNIFICANT EXPENSES AND 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 that are important to our
business. Any claims could result in costly litigation, divert the efforts of
our technical and management personnel, cause product shipment delays, require
us to enter into royalty or licensing agreements or prevent us from making or
selling certain products. Any of these could seriously harm our operating
results. Royalty or licensing agreements, if available, may not be available on
commercially reasonable terms, if at all. In addition, in some of 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. Costs associated with these indemnification obligations could be
significant and could cause our operating results and stock price to decline.

WE MAY NOT BE ABLE TO LICENSE NECESSARY THIRD-PARTY TECHNOLOGY OR IT MAY BE
EXPENSIVE TO DO SO.

    From time to time, we may be required to license technology from third
parties to develop new products or product enhancements. We have licensed
software for use in our products from Lucent Technologies, TCSI Inc., Trillium
Digital Systems Inc., and Wind River Associates. We cannot assure you that
third-party licenses will be available to us on commercially reasonable terms,
if at all. The inability to obtain any third-party license required to develop
new products and product enhancements could require us to obtain substitute
technology of lower quality or performance standards or at greater cost which
could seriously harm our competitive position, revenues and growth prospects.

    There are a number of general GSM patents held by different companies which
may impact our technology. If any of our products infringe on any of these
patents and we are unable to negotiate license agreements, then we may be
required to redesign a portion of our product line.

WE MAY BE UNABLE TO MEET OUR FUTURE CAPITAL REQUIREMENTS WHICH WOULD LIMIT OUR
ABILITY TO GROW AND COMPETE EFFECTIVELY, RESULTING IN SUBSTANTIAL HARM TO OUR
BUSINESS AND RESULTS OF OPERATIONS.

    We may require additional funding, which may not be available on terms which
are favorable to us. Currently, we do not have a credit facility or any lines of
credit. If we issue equity securities, existing shareholders may experience
dilution or the new equity securities may have rights, preferences and
privileges senior to those of existing shareholders. If additional funds are
raised through the issuance of debt securities, such securities would have
rights, preferences and privileges senior to holders of

                                       36
<PAGE>
common shares. If we cannot raise funds on terms favorable to us, we may not be
able to develop or enhance our products, take advantage of future opportunities
or respond to competitive pressures or unanticipated requirements. See "Use of
Proceeds," "Dilution" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources" for more
information on our capital requirements.

CONTROL BY OUR EXISTING SHAREHOLDERS COULD DISCOURAGE THE POTENTIAL ACQUISITION
OF OUR BUSINESS.

    As of September 13, 2000, our executive officers, directors and 5% or
greater shareholders and their affiliates owned 17.7 million shares or
approximately 36.6% of our outstanding common shares assuming the exercise of
all warrants and options held by them. Acting together, these shareholders would
be able to control all 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 control of our business or otherwise
discouraging a potential acquirer from attempting to obtain control of us, which
could prevent our shareholders from realizing a premium over the market price
for their common shares.

OUR BY-LAWS MAY DISCOURAGE POTENTIAL ACQUISITIONS OF OUR BUSINESS.

    Some of our by-laws and Bermuda law may discourage, delay or prevent a
merger or acquisition that shareholders may consider favorable. This may reduce
the market price of our common shares. A summary of these provisions is included
in "Description of Share Capital--Antitakeover Effects of Some Provisions of
Memorandum of Association and By-laws."

OUR BY-LAWS PROVIDE FOR WAIVER OF CLAIMS BY SHAREHOLDERS AND INDEMNIFY DIRECTORS
AND OFFICERS.

    Our by-laws provide for a broad indemnification of actions of directors and
officers. Under the by-laws, the shareholders agree to waive claims against
directors and officers for their actions in the performance of their duties,
except for acts of fraud or dishonesty. These waivers will not apply to claims
arising under the United States federal securities laws and will not apply to
the extent that they conflict with provisions of the laws of Bermuda or with the
fiduciary duties of our directors and officers.

OUR OPERATIONS BASED IN BERMUDA MAY BE SUBJECT TO UNITED STATES TAXATION, WHICH
COULD SIGNIFICANTLY HARM OUR BUSINESS AND OPERATING RESULTS.

    Except for our United States subsidiary, we do not consider ourselves to be
engaged in a trade or business in the United States. Our United States
subsidiary is subject to United States taxation on its worldwide income, and
dividends from our United States subsidiary are subject to United States
witholding tax. We and our non-U.S. subsidiaries would, however, be subject to
United States federal income tax on income related to the conduct of a trade or
business in the U.S. If we were determined to be subject to United States
taxation, our financial results would be significantly harmed. We cannot assure
you that the Internal Revenue Service will not contend that our Bermuda-based
operations are engaged in a United States trade or business and, therefore, are
subject to United States income taxation. See "Taxation" for more information on
the tax consequences of operating outside the United States.

A SUBSTANTIAL NUMBER OF OUR COMMON SHARES ARE AVAILABLE FOR SALE IN THE PUBLIC
MARKET SIMULTANEOUSLY, WHICH COULD CAUSE THE MARKET PRICE OF OUR SHARES TO
DECLINE.

    Sales of substantial amounts of our common shares in the public market or
the awareness that a large number of shares is available for sale could cause
the market price of our common shares to decline. Upon the expiration on
July 27, 2000 of lock-up agreements restricting the sale of shares by

                                       37
<PAGE>
our current shareholders, 35,458,187 of our common shares became eligible for
immediate sale. Sales of our common shares held by existing shareholders could
cause the market price of our shares to decline.

BECAUSE WE DO NOT INTEND TO PAY ANY CASH DIVIDENDS ON OUR COMMON SHARES, HOLDERS
OF OUR COMMON SHARES WILL NOT BE ABLE TO RECEIVE A RETURN ON THEIR SHARES UNLESS
THEY SELL THEM.

    We have never paid or declared any cash dividends on our common shares or
other securities and intend to retain any future earnings to finance the
development and expansion of our business. We do not anticipate paying any cash
dividends on our common shares in the foreseeable future. Unless we pay
dividends, our shareholders will not be able to receive a return on their shares
unless they sell them.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISKS

    Our financial market risk includes risks associated with international
operations and related foreign currencies. We anticipate that international
sales will continue to account for a significant portion of our consolidated
revenue. Our international sales are generally in U.S. dollars and therefore are
not subject to foreign currency exchange risk. Expenses of our international
operations are denominated in each country's local currency and therefore are
subject to foreign currency exchange risk; however, through June 30, 2000, we
have not experienced any significant negative impact on our operations as a
result of fluctuations in foreign currency exchange rates.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
interWAVE Communications International, Ltd.:

    We have audited the accompanying consolidated balance sheets of interWAVE
Communications International, Ltd. and subsidiaries as of June 30, 2000 and
1999, and the related consolidated statements of operations, shareholders'
equity and comprehensive loss, and cash flows for each of the years in the three
year period ended June 30, 2000. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

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

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of interWAVE
Communications International, Ltd. and subsidiaries as of June 30, 2000 and
1999, and the results of their operations and their cash flows for each of the
years in the three year period ended June 30, 2000 in conformity with accounting
principles generally accepted in the United States of America.

  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FISCAL YEARS ENDED JUNE 30, 2000,
                                 1999 AND 1998

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) DESCRIPTION OF BUSINESS

    interWAVE Communications International, Ltd. (the Company) develops,
manufactures and markets compact mobile wireless network solutions for GSM
wireless communications on a global basis. The Company's products are primarily
marketed to communication equipment providers, wireless service providers and
systems integrators.

    The Company has a fiscal year that ends on the Friday nearest June 30.
Fiscal 2000 and 1998 were 52-week years. Fiscal 1999 was a 53-week year. For
presentation purposes the accompanying consolidated financial statements and
notes refer to the calendar month-end.

(b) BASIS OF ACCOUNTING AND CONSOLIDATION

    The consolidated financial statements of the Company are presented in
conformity with generally accepted accounting principles as adopted in the
United States, the instructions to Form 10-K and the rules and regulations of
the Securities and Exchange Commission.

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries: interWAVE Communications, Inc. (Delaware,
USA); interWAVE Communications B.V. (Netherlands); interWAVE Communications
Solutions Ltd. (United Kingdom); and interWAVE Communications, S.A. (France).
The Company also operates a branch office in Hong Kong. All intercompany
balances and transactions have been eliminated in consolidation.

(c) INITIAL PUBLIC OFFERING

    On January 28, 2000, the Securities and Exchange Commission declared
effective the Company's Registration Statement on Form F-1. Pursuant to this
Registration Statement, the Company completed an initial public offering of
9,775,000 of its common shares (including 1,275,000 shares sold pursuant to the
exercise of the Underwriters' over-allotment option) at an initial public
offering price of $13.00 per share ("Offering"). The Offering was managed by
Salomon Smith Barney, Banc of America Securities LLC and SG Cowen. Proceeds to
the Company, after deduction of the Underwriters' discount and commission and
offering costs of approximately $1.9 million totaled approximately
$116.3 million.

    Upon completion of the Offering, the Company's preferred shares were
converted into 27,929,269 of common shares, and all outstanding preferred shares
were cancelled and retired.

(d) CURRENCY TRANSLATION

    For operations outside of the United States with the local currency as the
functional currency, assets and liabilities are translated at year-end exchange
rates, and statements of operations are translated at the average exchange rates
during the year. Adjustments arising from translation of non-U.S. currency
denominated assets and liabilities for these operations are included as a
component of other comprehensive income in shareholders' equity.

    For non-U.S. operations with the U.S. dollar as the functional currency,
non-U.S. currency denominated assets and liabilities are remeasured into U.S.
dollars using historical rates and any measurement gains and losses are included
in the consolidated results of operations and, to date, have not been
significant.

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
(e) CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Investments with an
original maturity of more than three months are classified as short-term
investments.

    Cash equivalents and short-term investments are classified as
"available-for-sale."

    The amortized cost of available-for-sale securities are adjusted for
amortization of premiums and accretion of discounts to maturity. Such
amortization is included in net investment income. Available-for-sale securities
are recorded at fair value. Unrealized gains and losses are reported as a
separate component of accumulated other comprehensive income in shareholders'
equity. Realized gains and losses and declines in value judged to be other than
temporary on available-for-sale securities are included in net investment
income. The cost of securities sold is based on the specific identification
method. Interest on securities classified as available-for-sale are included in
interest income.

(f) CONCENTRATION OF RISK

    Financial instruments, which potentially subject the Company to a
concentration of credit risk, principally consist of trade receivables. The
Company performs ongoing credit evaluations of its customers and generally does
not require collateral on trade receivables, as a majority of the Company's
customers are large, well established companies.

    The following table summarizes information relating to the Company's
significant customers with balances greater than 10% of trade receivables as of:

------------------------

(1) Hutchison Telecommunications Group includes HutchMax and Lanka Cellular
    Systems.

(2) Microcellular Systems, Ltd. was created by a spin-off from ADC
    Telecommunications in May 1999. See "Subsequent Events" Note 15.

(g) INVENTORIES

    Inventories are stated at the lower of average cost or market.

(h) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost, less accumulated depreciation,
calculated using the straight-line depreciation method over the estimated useful
lives of the related assets, generally two to five years. Leasehold improvements
are depreciated over the life of the underlying lease or the estimated useful
life, whichever is shorter.

(i) REVENUE RECOGNITION

    Equipment revenue is recognized when all of the following have occurred: the
product has been shipped, title and risk of loss have passed to the customer
(generally at time of shipment for U.S. shipments and at time of arrival at an
international port for non-U.S. shipments), we have the right to invoice the
customer, collection of the receivable is probable, and we have fulfilled all
pre-sale contractual obligations to the customer. Revenue from extended warranty
coverage and customer support is recognized ratably over the period of the
service contract. Trial sales made directly to wireless service providers are
not recognized as revenue until the trial is successfully completed. Trials
conducted by communications service providers and systems integrators are
normally shipped from their inventory and do not result in any incremental
revenue to us. Although the Company's products contain a software component, the
software is not sold separately and the Company is not contractually obligated
to provide software upgrades to its customers.

    The Company provides for estimated warranty costs at the time of sale. Sales
agreements include a 12 to 16 month warranty on all hardware and software.

                           1999 AND 1998 (CONTINUED)

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
(j) RESEARCH AND DEVELOPMENT COSTS

    Statement of Financial Accounting Standard (SFAS) No. 86 provides for the
capitalization of certain software development costs once technological
feasibility is established subject to an evaluation of realizability.
Capitalized costs are then amortized on a straight-line basis over the estimated
product life or based on the ratio of current revenues to projected product
revenues, whichever is greater. To date, the Company's products have been
available for general release concurrent with the establishment of technological
feasibility; and, accordingly, no development costs have been capitalized.

(k) INTANGIBLES

    The Company capitalizes costs of acquiring licenses from third parties for
technologies that have reached technological feasibility and can be incorporated
into the Company's products. The Company also capitalizes certain external costs
associated with patents and trademarks. Except for the license and technical
information agreement discussed in Note 9(a), the Company amortizes these assets
straight line over four years or based on the ratio of current revenues to
projected revenues whichever is greater.

(l) IMPAIRMENT OF LONG-LIVED ASSETS

    The Company evaluates its long-lived assets, including certain identifiable
intangibles, for impairment whenever events or changes in circumstances indicate
that the carrying amount of such assets might not be recoverable. Recoverability
of assets to be held and used is measured by a comparison of the carrying amount
of an asset to future net cash flows expected to be generated by the asset. If
such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the asset exceeds the
fair value of the asset. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell. To date the Company has
made no adjustment to the carrying value of its long-lived assets.

(m) INCOME TAXES

    The Company uses the asset and liability method of accounting for income
taxes. Deferred tax assets and liabilities are recognized for the estimated
future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases. Deferred tax assets and liabilities are measured using
enacted tax rates in effect for the year in which those temporary differences
are expected to be recovered or settled. Valuation allowances are established
when necessary to reduce deferred tax assets to the amounts expected to be
realized.

(n) LOSS PER SHARE

    The denominator used in the computation of basic and diluted net loss per
share is the weighted average number of common shares outstanding for the
respective period. All potentially dilutive securities were excluded from the
calculation of diluted net loss per share, as the effect would be anti-dilutive.
Diluted shares outstanding includes the assumed conversion of preferred shares.

(1) THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
(o) STOCK-BASED COMPENSATION AND WARRANTS FOR GOODS AND SERVICES

    The Company accounts for stock-based awards to employees using the intrinsic
value method. Expense associated with stock-based compensation is being
amortized on an accelerated basis over the vesting period of the individual
award.

    Warrants issued for goods or services are valued at the fair value of the
equity instrument or the goods or services received, whichever is more readily
determinable. Promises of future services are recorded as contra-equity until
such time as the services are received.

(p) USE OF ESTIMATES

    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

(q) COMPREHENSIVE INCOME

    "Other comprehensive income" refers to revenues, expenses, gains and losses
that are not included in net income, but rather are recorded directly in
shareholders' equity. The only component of other comprehensive income for the
years ended June 30, 1998 and 1999 was cumulative translation adjustments. The
components of other comprehensive income for the year ended June 30, 2000 were
cumulative translation adjustments and unrealized investment losses.

(r) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying value of cash, cash equivalents, trade receivables, accounts
payable and accrued expenses, other current liabilities and convertible notes
approximate fair value due to the short maturity of those instruments. The
carrying value of the notes payable approximate fair value due to the variable
interest rates on these notes.

    The net change in the total valuation allowance from the year ended
June 30, 2000 and 1999 was an increase of approximately $16,038,000 and
$4,888,000, respectively. Management believes that sufficient uncertainty exists
regarding the future realization on deferred tax assets and accordingly, a
valuation allowance is required.

    The company has net operating loss carryforwards for federal and California
income tax return purposes of approximately $61,096,000 and $31,848,000,
respectively. The net operating losses expire in the following years in the
following amounts:

    The company also has foreign net operating losses in France of $133,000;
which expire in 2002.

    The Company also has research credit carryforwards for U.S. federal and
California income tax return purposes of approximately $2,735,000 and
$1,662,000, respectively. The federal research credit carryforwards will expire

credits of approximately $36,000, which carry forward indefinitely until
utilized. The Company also has California manufacturer's investment credit
carryforwards of approximately $639,000, which expire in 2006 through 2010.

(7) EQUIPMENT LINE OF CREDIT

    During 1997, the Company obtained a secured equipment line of credit of
$2,500,000. Borrowings bear interest at 6% above the average term Treasury Note
two weeks preceding a drawdown. The Company had $486,000 outstanding under the
secured equipment line of credit as of June 30, 2000, the entire amount is
included in current portion of notes payable. As of June 30, 1999, the Company
had $1,073,000 outstanding under the secured equipment line of credit, of which
$486,000 is included in long-term liabilities and $587,000 is included in
current portion of notes payable. The Company does not have the ability to
borrow additional amounts under this facility. Borrowings under the line of
credit are payable monthly with the final payments due in July 2001.

(8) CONVERTIBLE NOTES

    In March 1999, as part of a bridge financing the Company issued $12,691,830
of convertible notes payable to a group of its preferred and common shareholders
in exchange for $12,163,965 in cash and a note receivable of $527,865. As of
June 30, 1999, the convertible notes, including accrued interest of $231,211
amounted to $12,923,041. The principal amount, together with interest accrued at
8% per annum, would have been due and payable on December 3, 1999 or
automatically converted into a new series of preferred shares upon the closing
of a minimum of $10 million of a new series of preferred shares to new
investors. As a result of the issuance of Series H-1 preferred shares on
September 9, 1999, the notes converted to Series H-1 preferred shares at a price
of $7 per share. As an incentive to participate in the convertible note
financing, current holders of Series A, B, C, D, E, F and G preferred shares
("original preferred shares") who participated at a minimum level based on their
respective ownership percentage were entitled to exchange their original
preferred shares for A-1, B-1, C-1, D-1, E-1, F-1 and G-1 preferred shares,
respectively ("new preferred shares"), whose terms were identical to the
original preferred shares, except that the new preferred shares would be
preferential in liquidation to all original preferred shares. All of the
preferred shares converted to common shares on a one-for-one basis on the
Company's "initial public offering."

    In conjunction with the bridge loan financing, the participants in the
convertible notes were granted a warrant to purchase one share of common shares
for each $2 invested in the convertible notes. As a result, the Company issued
warrants to purchase 6,345,939 shares of common shares at a price of $0.70 per
share, which are exercisable any time for a period of 5 years from date of
issuance. The proceeds from the bridge financing were allocated between the
convertible notes and the warrants based upon their relative fair values. The
amount of $5,592,552 (net of proportionate value of note receivable of $284,466)
ascribed to the warrants was estimated using the Black-Scholes option valuation
model with the following assumptions: no expected dividend yield; risk free
interest rate of 6%;

expected volatility 70%; and contractual term of 5 years. The value of the
warrants had been recorded as a discount on the convertible notes payable and
additional paid-in-capital and will be amortized over the term of the debt.

    The note receivable of $527,865 has been recorded as a reduction of the
convertible notes of $243,399 and a reduction of the warrants of $284,466
determined on a basis proportionate to the fair value of the bridge loan and
warrants.

    As of June 30, 2000 1,893,662 warrants have been exercised. Interest expense
of $1,921,447 and $1,921,567 has been recorded in connection with the
amortization of the discount in fiscal 2000 and 1999, respectively.

    On September 10, 1999, the Company completed an offering of 1,715,715 shares
of Series H-1 preferred shares and issued warrants to purchase an aggregate of
240,000 shares of common shares at $1 per share to a group of investors in
exchange for $12,010,000 (before financing costs of $766,000). The Series H-1
contained a $7 per share liquidation preference and converted to common shares
on a one-to-one basis. The warrants valued at $1,340,000 expire three years from
the issuance date, or upon the effectiveness of an initial public offering,
whichever comes first, unless previously exercised. All of the warrants were
exercised upon the Company's initial public offering. The fair value of the H-1
preferred and common shares at time of issuance of Series H-1 was deemed to be
$7.50 per share, resulting in recognition of a dividend at the time of issuance
(a beneficial conversion) of $2,055,000. The sale of Series H-1 preferred shares
met the minimum $10 million new financing described in footnote 8, and resulted
in the automatic conversion of the convertible notes and interest accrued
thereon into 1,872,362 shares of Series H-1 and the issuance of warrants to
purchase 253,874 shares of common shares for $1 per share to the note holders.
The warrants expire three years from the issuance date, or upon the
effectiveness of an initial public offering, whichever comes first, unless
previously exercised.

    In September 1999, the Company entered into a memorandum of understanding
expiring in August 2000 with an investor to distribute and manufacture the
investor's products and for the investor to market the company's products in
Canada. The Company expects to enter into a four-year distribution agreement. In
conjunction with the memorandum of understanding the Company issued a

warrant to purchase 615,000 common shares at an exercise price of $1 per share
and received a warrant to purchase 225,225 shares of the investor's publicly
traded common shares at $3.3125 per share expiring in August 2002. The warrant
to purchase the Company's common shares was exercised during the current fiscal
year.

    The amount of $475,688 ascribed to the warrants received by the Company was
estimated using the Black-Scholes option valuation model with the following
assumptions: no expected dividend yield; risk free interest rate of 6%; expected
volatility of 81%; and contractual term of 3 years. The warrant received was
recorded in other assets as of September 30, 1999.

    The amount of $4,121,688 ascribed to the warrants issued to the investor was
estimated using the Black-Scholes option valuation model with the following
assumptions: no expected dividend yield; risk free interest rate of 6%; expected
volatility of 70%; and contractual term of 3 years. The warrant was recorded as
additional paid in capital. The amount of $3,646,000 ascribed to the services to
be received from the investor was determined as the difference in value between
the warrants exchanged. This amount has been recorded as contra equity and will
be amortized to expense over the four year term of the distribution agreement.

    In November 1999, the Company completed an offering of 1,526,663 Series I-1
preferred shares to Alcatel in exchange for $12,013,304 (net of financing costs
of $200,000). The Series I-1 contained an $8 per share liquidation preference
and converted to common shares on a one-to-one basis. In connection with the
sale of Series I-1 preferred shares, the Company and Alcatel entered into a
purchase and distribution agreement whereby Alcatel will market the Company's
wireless office network products through Alcatel's enterprise solutions
division.

    In December 1999, the Company sold 2,000,000 Series I-1 preferred shares to
Holodeck for $16 million on similar terms as the November 1999 sale of shares to
Alcatel.

(b) SHARE OPTION PLAN

    In fiscal 1995, the Board of Directors adopted the 1994 Share Plan (the
Plan) providing for the issuance of common share options to employees and
consultants of the Company. The share options are a combination of both
incentive and non-statutory share options.

    Incentive share options may be granted at not less than 100% of the fair
market value per share, and non-statutory share options may be granted at not
less than 85% of the fair market value per share at the date of grant as
determined by the Board of Directors or committee thereof, except for options
granted to a person owning greater than 10% of the total combined voting power
of all classes of shares of the Company, for which the exercise price must not
be less than 110% of the fair market value. Share option plan shares generally
vest 25% after one year, with the remainder vesting monthly over the following
three years. Additional options granted to existing employees after July 28,
1998 are in general vesting monthly over four years.

    The Company uses the intrinsic value method to account for the 1994 plans.
Accordingly compensation cost has been recognized for its stock options in the
accompanying financial statements if, on the date of grant, the current market
value of the underlying common shares exceeded the exercise price of the stock
options at the date of grant.

(9) PREFERRED AND COMMON SHARES (CONTINUED)
    During fiscal 2000, 1999 and 1998, the Company granted options with a
weighted-average exercise price of $5.46, $0.90 and $1.15 respectively, compared
to the weighted-average fair value of approximately $2.74, $3.03 and $6.37 for
the same respective periods.

    Options generally have 10 year terms. However, options granted to an
optionee who, at the time the option is granted, owns shares representing more
than 10% of the voting power of all classes of shares of the Company, generally
have 5 year terms.

    The Company has reserved 10,730,000 common shares for issuance under the
Plan. A summary of the Company's share option plan activity is as follows:

    Under SFAS No. 123, Accounting for Stock-Based Compensation, the Company is
required to disclose the pro forma effects on net loss and net loss per share as
if the Company had elected to use the fair value approach to account for all of
its employee stock-based compensation plans. Had compensation cost for the
Company's plans been determined consistently with the fair value approach
described in SFAS No. 123, the Company's pro forma net loss and pro forma net
loss per share for the years ended June 30, 2000, 1999 and 1998, would have been

    The Company's facilities in Redwood City were subleased during March, 2000
and the payments of approximately $1.7 million received from the subleases will
cover our proportionate costs to the landlord under the existing lease. The
subleases will terminate at the same time that our lease ends on September 30,
2002.

    Rent expense was approximately $1,950,000, $961,000, and $822,000 for the
years ended June 30, 2000, 1999, and 1998, respectively.

(11) COMMITMENTS (CONTINUED)
(b) CONTRACT MANUFACTURERS

    The Company generally commits to purchase products from its contract
manufacturers to be delivered within the most recent 60 days covered by
forecasts with cancellation fees. As of June 30, 2000, the Company had committed
to make purchases totaling $7.5 million from these manufacturers in the next
60 days. In addition, in specific instances, the Company may agree to assume
liability for limited quantities of specialized components with lead times
beyond this 60-day period.

(12) LITIGATION

    On June 28, 1999, the Company filed a complaint against JetCell Corporation
in United States District Court alleging misappropriation of trade secrets and
patent infringement. The complaint seeks injunctive relief and damages. On
July 19, 1999, JetCell filed an answer to the complaint and a series of
counterclaims against the Company. The answer denied the allegations made in the
complaint and the counterclaims included allegations against the Company of
unfair trade practices, unfair competition, defamation, and patent misuse. The
answer and counterclaims seek injunctive relief, damages, invalidation of the
Company's patents and a dismissal of the complaint. On August 9, 1999 we filed
an awswer to JetCell's counter claims denying the allegation made in the counter
claims. The Company is unable to predict the outcome of the lawsuit and does not
expect it to be resolved in the near future. However, if the Company is unable
to settle these proceedings in a satisfactory manner, the legal proceedings may
be time consuming and expensive and the outcome could be adverse to the Company.
If the outcome is adverse to the Company, we would experience more competition
in the Company's markets and may be required to license technology required for
the Company's products, either of which could harm the Company's business and
financial results. An adverse outcome could have a material adverse effect on
our financial position. In May 2000 JetCell was acquired by Cisco Systems, Inc.
("Cisco"). Cisco was substituted for JetCell and Cisco is now the defendant.

(13) EMPLOYEE BENEFIT PLANS

    The Company maintains a 401(k) defined contribution benefit plan that covers
all U.S. employees who have attained the age of at least 20.5 years. This plan
allows employees to defer up to 20% of their pretax salary in certain
investments at the discretion of the employee. In addition, effective July 1,
1999, the Company amended the Plan to provide for a 100% vested Employer
Matching Contribution equal to 10% of the amount a participant elects to defer
as an elective contribution to the Plan up to a maximum of $1,000 during a plan
year. The Company had matching contributions to the Plan of $48,000 for the year
ended June 30, 2000, however, no matching contributions were made during the
years ended June 30, 1999 and 1998.

    The Company has a Employee Stock Purchase Plan (ESPP), under which eligible
employees may authorize payroll deductions of up to 15 percent of their
compensation, as defined, to purchase common shares at a price of 85 percent of
the lower of the fair market value as of the beginning or the end of the
offering period.

(14) SEGMENT INFORMATION

    In fiscal 1999, the Company adopted SFAS No. 131, DISCLOSURES ABOUT SEGMENTS
OF AN ENTERPRISE AND RELATED INFORMATION. SFAS No. 131 establishes standards for
the manner in which public companies report information about operating segments
in annual and interim financial statements. It also establishes standards for
related disclosures about products and services, geographic areas, and major
customers. The method for determining what information to report is based on the
way management organizes the operating segments within the Company for making
operating decisions and assessing financial performance. The Company's chief
operating decision-maker is considered to be the chief executive officer (CEO).
The financial information reviewed by the CEO is identical to the information
presented in the accompanying statements of operations. Therefore, the Company
has determined that it operates in a single operating segment: manufacturing and
sale of compact mobile wireless network solutions.

    Due to the nature of our business, shipments are frequently made to a
systems integrator located domestically or in a given country, only to be
repackaged and shipped to another country for actual installation. Geographic
revenue information for the fiscal years 2000, 1999, and 1998 is based on our
customers' location. Long-lived assets include property, plant and equipment.
Property, plant and equipment information is based on the physical location of
the asset at the end of each fiscal year.

    Net revenues from unaffiliated customers by geographic region were as

(15) SUBSEQUENT EVENTS (UNAUDITED)

    In July 2000, the Company purchased all of the outstanding shares of
Microcellular Systems Limited, an Irish company, for approximately
$13.5 million. This consideration is comprised of $3.1 million in cash, 555,556
shares of interWAVE common shares and the assumption of approximately
$3.1 million of Microcellular's liabilities. In addition, the Company committed
future consideration of up to $2.5 million in cash payments to current

achievement of certain sales objectives for the period from July 2000 through
June 2001, payable by August 31, 2001.

    Microcellular Systems Limited is a systems integrator and service provider
focused on worldwide microcellular GSM systems. The acquired business has
offices in Ireland, England, China, and California.

    The Company will treat the acquisition as a purchase. The total purchase
consideration will be allocated to the assets acquired and liabilities assumed
based on their estimated fair values as of July 28, 2000. Goodwill represents
the excess of purchase consideration over the fair value of assets, including
identifiable intangible assets, net of the fair value of liabilities assumed.
This allocation process is not complete, but based upon preliminary estimates
the Company anticipates that goodwill of approximately $8.0 million will be
recorded, including the estimated contingent consideration.

CONSOLIDATED SUPPLEMENTARY DATA

    The following table sets forth certain unaudited condensed consolidated
statement of operations data for each quarter of 1999 and 2000. This data has
been derived from unaudited condensed consolidated financial statements and, in
the opinion of management, includes all adjustments, consisting of normal
recurring adjustments, necessary for a fair presentation of the information when
read in conjunction with the consolidated financial statements and notes
thereto. Our quarterly results have in the past been and may in the future be
subject to significant fluctuations. As a result, we believe that results of
operations for interim periods should not be relied upon as an indication of the
results to be expected in future periods.
