                               NETRO CORPORATION

      We are a leading provider of intelligent broadband wireless access systems
to competitive communications service providers worldwide. Our AirStar system
allows service providers to rapidly and cost effectively offer integrated voice
and high-speed packet data services to their business subscribers. We have
engineered AirStar to support broad service rollouts and to operate at a number
of different licensed frequencies worldwide. AirStar derives its
price-performance benefits from dynamic bandwidth allocation and an intelligent
point-to-multipoint architecture. We believe that AirStar is one of the first
commercially available broadband wireless access systems providing integrated
voice and high-speed data services using a point-to-multipoint architecture.

      We began shipping the beta AirStar system to service providers in the
third quarter of 1998. The AirStar system is currently deployed in trials or
initial commercial deployments in 17 service providers and enterprises
worldwide. Most of these service providers are served through our strategic
relationships with Lucent and Siemens/Italtel.

      In recent years, the volume of high-speed data traffic across
communications networks worldwide has grown dramatically as the public Internet
and private corporate intranets have become essential for communications and
e-commerce. This traffic growth has created demand for cost-effective, broadband
network access, as business users increasingly rely on high-bandwidth network
applications and content. Increased deregulation has enabled a number of
competitive service providers to provide local network access that has
historically been offered exclusively by the incumbent provider in a given
geographical region. There are a number of alternatives to deliver broadband
access through existing or new wireline infrastructures, but technical,
performance, cost or availability issues often limit the ability of these
alternatives to satisfy the access needs of service providers and businesses
worldwide. Broadband wireless offers competitive service providers the ability
to rapidly provide service to large numbers of businesses without the
constraints of a legacy wireline infrastructure.

      Competitive service providers deploying broadband wireless networks today
must differentiate their services to a wide base of business users and compete
effectively with services offered through fiber, leased lines, DSL and cable
modems. Our system is designed to address these needs and deliver the following
benefits to service providers:

      Service Integration and Bandwidth on Demand.  Service providers using
AirStar's intelligent wireless transport can support both voice and high-speed
packet data services on the same system, enabling them to increase revenue from
their licensed spectrum. AirStar allows service providers to offer symmetrical
broadband services, with on-demand burst rates up to 8 Mbps.

      Cost-Effective Deployment and Operation.  AirStar allows a competitive
service provider to compete effectively in the broadband access market. AirStar
is designed to provide for low overall system costs and enable success-based
capital deployment by directly linking network buildout expenditures to
subscriber growth. Additionally, AirStar's statistical multiplexing allows a
service provider to optimize spectrum use and the deployment of equipment by
expanding effective transmission capacity.

      Quality of Service and Reliability.  Service providers using AirStar can
deploy voice and high-speed packet data services at different price points to
different market segments with the option for guaranteed quality of service
levels and up to 99.999% availability. These capabilities allow a service
provider to match and guarantee delivered bandwidth to a particular business'
requirements and budget.

                                        1
<PAGE>   6

      Rapid Time to Market.  Service providers using AirStar can achieve rapid
time to market for integrated voice and high-speed data services through
AirStar's efficient installation, end-to-end network management integration and
intelligent wireless transport. By installing a single AirStar base station, the
service provider can attain coverage of many potential subscribers. For example,
a typical cell at 10 GHz or 26 GHz can cover ranges from 110 to 275 square miles
or 5 to 15 square miles, respectively, depending on local conditions, and has a
transmission capacity equivalent to approximately 400 to 450 T1 lines, or an
aggregate capacity of over 600 Mbps.

      Our objective is to be the leading supplier of broadband wireless access
systems used by competitive service providers at multiple licensed frequencies
worldwide. We intend to capitalize on early design wins with key service
providers to increase sales as these service providers deploy broadband services
more widely. Furthermore, as this occurs, we intend to utilize reference sales
and new product offerings to drive sales in new markets. We intend to leverage
our architecture to offer new features that will provide competitive advantages
to service providers. We are currently developing new products at new
frequencies to meet the needs of service providers worldwide. Additionally, we
intend to build upon the success that we have achieved through our strategic
relationships with Lucent and Siemens/Italtel to meet the needs of service
providers seeking to deploy large-scale networks and to expand our customer
base.

                                  RISK FACTORS

      Before investing in our common stock, you should be aware that there are
various risks, including those described below. As a Netro shareholder, you will
be subject to risks inherent in our business. The value of your investment may
increase or decline and could result in a loss. You should carefully consider
the following factors as well as other information contained in this prospectus
before deciding to invest in shares of our common stock.

WE HAVE A LIMITED OPERATING HISTORY AND OUR BUSINESS MODEL IS UNPROVEN AND MAY
NOT SUCCEED

      We have a very limited operating history. We were incorporated in November
1994 and have generated only limited revenues to date, most of which have come
from sales of a predecessor point-to-point product, AirMAN, and customer trials
of AirStar, our current point-to-multipoint product. In addition, our business
model is evolving and relies on the success of competitive service providers and
the cost competitiveness of broadband wireless access solutions compared to
wireline solutions. Due to our limited operating history, it is difficult for us
to predict future results of operations, and you should not expect future
revenue growth to be comparable to our recent revenue growth. In addition, we
believe that comparing our operating results for different periods is not
meaningful, and that therefore, you should not rely on the results for any
period as an indication of our future performance. Investors in our common stock
must consider our business and prospects in light of the risks typically
encountered by companies in their early stages of development, particularly
those in rapidly evolving markets such as the communications equipment industry
and the emerging communication services industry. Some of these risks, in
addition to those risks discussed elsewhere in this "Risk Factors" section,
include:

        - a history of losses and potential for future losses;

        - significant fluctuations in quarterly operating results;

        - the intensely competitive market for telecommunications equipment;

        - the challenges encountered in expanding our sales organization;

        - the risks relating to the timely introduction of new products and
          product enhancements; and

        - the risks associated with the expansion of our field support
          infrastructure.

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

      As of March 31, 1999, we had an accumulated deficit of $74.6 million, and
we expect to continue to incur net losses. We anticipate continuing to incur
significant sales and marketing, research and development and general and
administrative expenses and, as a result, we will need to generate significantly
higher revenues to achieve and sustain profitability. We incurred net losses of
approximately $12.2 million, $24.5 million, $28.8 million and $7.0 million in
1996, 1997 and 1998 and the three months ended March 31, 1999. Our financial
results to date are largely based on sales of AirMAN and customer trials of
AirStar. Although our AirStar revenues have grown in recent quarters, our past
results should not be relied on as indications of future performance. We cannot
be certain that we will realize sufficient revenues to achieve and sustain
profitability.

OUR OPERATING RESULTS ARE SUBJECT TO MANY FACTORS, SOME OF WHICH ARE OUTSIDE OF
OUR CONTROL, THAT COULD CAUSE OUR QUARTERLY OPERATING RESULTS TO FLUCTUATE AND
OUR STOCK PRICE TO BE VOLATILE

      Our quarterly and annual operating results have fluctuated in the past and
are likely to fluctuate significantly in the future due to a variety of factors,
some of which are outside of our control. Our operating results to date are
largely based on sales of AirMAN and customer trials of AirStar. It is likely
that in some future quarter our operating results may fall below the
expectations of securities analysts and investors. In this event, the trading
price of our common stock could significantly decline.

                                        4
<PAGE>   9

      Some of the factors that could affect our quarterly or annual operating
results include:

        - our ability to attain and maintain production volumes and quality
          levels for our products;

        - our ability to obtain sufficient supplies of sole source or long
          lead-time components for our products;

        - our ability to achieve cost reductions;

        - the size, timing and frequency of network buildouts, which are
          typically large and infrequent;

        - the timing and amount of, or cancellation or rescheduling of, orders
          for our products, particularly large orders from our key distributors
          and system integrators;

        - our ability to develop, introduce, ship and support new products and
          product features and to manage product transitions; and

        - a decrease in the average selling prices of our products.

      Service providers and system integrators may delay delivery schedules or
cancel their orders without notice. Due to these and other factors, quarterly
revenues, expenses and results of operations could vary significantly in the
future, and you should not rely on period-to-period comparisons as indications
of future performance.

WE HAVE NOT MANUFACTURED OUR PRODUCTS IN SUBSTANTIAL VOLUMES. IF WE ARE UNABLE
TO DO SO IN A COST-EFFICIENT WAY, OUR MANUFACTURING COSTS WILL BE HIGHER THAN
EXPECTED, WHICH WOULD ADVERSELY AFFECT OUR BUSINESS

      We have not manufactured our products in large volumes. We manufacture
only small quantities of our products at our own facilities, and we have only
recently begun limited quantity manufacturing runs with two contract
manufacturers. If we or our manufacturers are unable to develop processes by
which we can manufacture substantial volumes of our products at the required
quality and expected costs in relatively short periods of time, our financial
results will suffer. Manufacturing our products, particularly the radio elements
of our products, is complex and difficult. One of our contract manufacturers
does not have a history of producing these elements on a large scale. We have no
substantial experience on which to base forecasts of customer orders, and,
consequently, we may be unable to meet demand or we may build an excess of
inventory with our contract manufacturers. Furthermore, if we do not achieve
economies of scale in manufacturing, our gross margins, and hence our operating
results, will not meet expectations. In addition, many of our contracts with
distributors and system integrators provide for financial penalties in the event
of a delay in delivery of products, which would adversely affect our business.

IF WE CANNOT REDUCE OUR MANUFACTURING COSTS, POTENTIAL CUSTOMERS WILL NOT
PURCHASE OUR PRODUCTS

      Market acceptance of our products will depend in part on reductions in the
unit cost of our products. We expect that as broadband access systems become
more widely deployed, the price of broadband access products will decline.
However, we may be unable to reduce the cost of our products sufficiently to
enable us to compete with other broadband access technologies or with access
lines leased from the incumbent carrier, commonly known as leased lines, prices
of which are generally declining. Our cost reduction efforts may not allow us to
keep pace with competitive pricing pressures or lead to improved gross margins.
In order to remain competitive, we must significantly reduce the cost of
manufacturing our products through design and engineering changes. We may not be
successful in redesigning our products. Even if we are successful, our redesign
may be delayed or may contain significant errors and product defects. In
addition, any redesign may fail to result in sufficient cost reductions to allow
us to significantly reduce the price of our products or improve our gross
margin.

<PAGE>   10

IF BROADBAND WIRELESS ACCESS TECHNOLOGY OR OUR IMPLEMENTATION OF THIS TECHNOLOGY
IS NOT ACCEPTED BY SERVICE PROVIDERS, WE WILL NOT BE ABLE TO SUSTAIN OR GROW OUR
BUSINESS

      Our future success is substantially dependent on whether broadband
wireless access technology gains market acceptance by a limited number of
service providers. We have invested substantial resources in the development of
this technology, and all of our products are based on this technology. Service
providers continuously evaluate alternative broadband access technologies,
including wireline technologies such as DSL, cable modem, optical fiber, leased
lines and different wireless technologies. In particular, competitive service
providers are able to use leased lines to offer service. The price of leased
lines has declined significantly in many countries. If this trend continues,
service providers might be more likely to use leased lines than our products,
which would adversely affect our market share and pricing. In addition,
widespread acceptance of broadband, point-to-multipoint wireless technology may
be hindered by inherent technological limitations, such as a need for a clear
line-of-sight for transmissions and a reduction in coverage radius in areas that
experience heavy rain. In the event that service providers adopt technologies
other than the broadband point-to-multipoint wireless technology that we offer,
we may not be able to sustain or grow our business.

THE MAJORITY OF SERVICE PROVIDERS THAT ARE EXPECTED TO USE OUR PRODUCTS ARE
EMERGING COMPANIES WITH LIMITED OPERATING HISTORIES. IF THESE SERVICE PROVIDERS
DO NOT SUCCEED, THERE WILL BE NO MARKET FOR OUR PRODUCTS

      Most communications service providers using our products are competitive
local exchange carriers, or CLECs, seeking to challenge service providers that
have had a historical monopoly in a given market. If these CLECs do not succeed,
there will be no market for our products. Many of these CLECs are still forming
their business models, building their infrastructures, acquiring spectrum
licenses and rolling out their services. These service providers have little or
no experience in deploying telecom or datacom services, marketing and
integrating a combination of voice and data solutions, or obtaining rights to
roof space, commonly known as roof rights. Neither they nor we have experience
in integrating an end-to-end service network. There is no proven business model
for competitive service providers providing end-to-end services, and,
consequently, there is no ability to forecast how successful these service
rollouts will be. These service providers require substantial capital for the
development, construction and expansion of their networks and the introduction
of their services. Financing may not be available to emerging service providers
on favorable terms, if at all. Additionally, many competitive service providers
may not be successful in obtaining rights to broadband spectrum. The inability
of emerging service providers to acquire and keep customers, acquire spectrum
licenses, successfully raise needed funds, or respond to any other trends such
as price reductions for their services or diminished demand for communications
services generally, could adversely affect their businesses or cause them to
reduce their capital spending on network buildouts. If competitive service
providers are forced to defer or curtail their capital spending programs, sales
of our products might be impacted, which would have an adverse effect on our
business.

WE HAVE A LONG SALES CYCLE, WHICH LIMITS OUR ABILITY TO PREDICT REVENUES

      We do not yet know what our typical sales cycle will be. System
integrators and service providers typically perform numerous tests and
extensively evaluate our products before incorporating them into networks. The
time required for testing, evaluation and design of our products into the
service provider's network typically ranges from six to twelve months. If a
service provider decides to supply commercial service with our products, it can
take an additional six to twelve months or more before a service provider
commences mass deployment of networks that incorporate our products. Because of
this potentially long sales cycle, we may experience a delay between the time
when we increase operating expenses and the time when we generate revenues, if
any, from these expenses. Some factors that affect the length of our sales cycle
include:

        - testing and evaluation;

        - acquisition of roof rights;

        - deployment and planning of network infrastructure;

                                        6
<PAGE>   11

        - complexity of network;

        - scope of project;

        - availability of spectrum; and

        - regulatory issues.

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

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

      We have launched our products only in small-scale installations and trial
deployments to date. Our products have not been deployed on a large scale.
Therefore, we cannot assure you that our products will work as we intend them to
work, including with respect to transmission speed, capacity and quality, nor
can we predict whether our products will sustain system failures in a
large-scale field deployment. In addition, our products may contain undetected
or unresolved errors when they are first introduced or as new versions are
released. Our products are integrated with other network elements. There may be
incompatibilities between these elements and our products that adversely affect
the service provider or its subscribers. As is common in our industry, errors
may be found in new products or upgrades, or there may be incompatibilities in
integrated systems as a whole, after their deployment. If our products do not
function in a large-scale deployment or in a network environment, or if there
are errors or defects in our products, we could experience:

        - delays in or loss of sales opportunities;

        - diversion of development resources;

        - injury to our reputation; and

        - increased service, warranty and replacement costs.

      Although we have set aside warranty and inventory reserves, we might
experience claims that exceed these reserves with respect to either our current
product or our discontinued point-to-point product.

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

      We sell most of our products through two system integrators. These system
integrators incorporate our products into larger networks that include equipment
manufactured by them or other parties. Aggregate sales through these two system
integrators accounted for approximately 31% of our revenues for 1998, and
approximately 88% of our revenues for the three months ended March 31, 1999.
Accordingly, unless and until we diversify and expand our customer base, our
future success will significantly depend on the timing and size of future
purchase orders, if any, from these two system integrators and, in particular:

        - the product requirements of these system integrators and their service
          provider customers;

        - the market success of these system integrators; and

        - the success of the networks deployed using our products.

      The loss of either of these system integrators or the delay of significant
orders from these system integrators, even if only temporary, could, among other
things:

        - reduce or delay our recognition of revenues;

        - harm our reputation in the industry; or

        - reduce our ability to accurately predict cash flow.

                                        7
<PAGE>   12

      We have no agreements for minimum purchase commitments from our system
integrators or other resellers. The amount and timing of resources that our
system integrators devote to our business is not within our control. Should
either of our system integrators cease to emphasize systems that include our
products, our revenues and consequently results of operations would be adversely
affected. Furthermore, our relationships with these system integrators are
non-exclusive. Therefore, to the extent that they elect to market alternative
broadband access solutions, such as cable modems or DSL, or our competitors'
broadband wireless products more aggressively or instead of our products, our
revenues and consequently results of operations would be adversely affected. For
instance, Siemens has an equity interest in, and an OEM relationship with, one
of our competitors, which may motivate Siemens to select this competitor's
solutions over our own in the future. Our major system integrators or their
affiliates may also acquire or form partnerships with our competitors or may
develop, support or market competing broadband access solutions. There are a
limited number of other system integrators that have the global reach, financial
resources or technical expertise to sell, service and integrate our products
effectively. Some of those other system integrators may market products that
compete with our products. If one or both of our system integrators will not
sell, service or integrate our products, and we cannot identify other system
integrators as replacements, we would be limited in our ability to sell our
products.

WE DEPEND ON TWO CONTRACT MANUFACTURERS.  IF THESE MANUFACTURERS ARE UNABLE TO
FILL OUR ORDERS ON A TIMELY BASIS, AND WE ARE UNABLE TO FIND ALTERNATIVE
SOURCES, WE MAY BE UNABLE TO DELIVER PRODUCTS TO MEET CUSTOMER ORDERS

      We currently have relationships with two contract manufacturers of our
products. We manufacture only small quantities of products at our own
facilities. Our reliance on contract manufacturers involves a number of risks,
in particular:

        - their need to develop high-speed testing and manufacturing methods;

        - the possibility that they may not devote adequate capacity to us; and

        - reduction of our control over delivery schedules, manufacturing yields
          and costs.

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

BECAUSE SOME OF OUR KEY COMPONENTS ARE FROM SOLE SOURCE SUPPLIERS OR REQUIRE
LONG LEAD TIMES, OUR BUSINESS IS SUBJECT TO UNEXPECTED INTERRUPTIONS

      Many of our key components have long lead times and are purchased from
sole source vendors for which alternative sources are not currently available.
For example, we purchase our Base Station Shelf from Cisco Systems, Inc.
pursuant to an agreement that terminates in February 2000. Cisco has recently
acquired interests in companies with broadband wireless technology, and we
cannot be certain that Cisco will continue to supply us after the termination of
the current agreement. While we plan to eliminate the reliance on the Cisco
shelf in future versions of our product and are in the process of both
developing our own alternative for the shelf and seeking third-party
alternatives for the shelf, engineering or other delays could hinder
introduction of these alternatives. Until we phase out the Cisco shelf, our
inability to obtain sufficient quantities of that shelf may result in delays or
reductions in product shipments, which could adversely affect our business. In
addition, we purchase most of our electronic boards from Solectron, one of our
contract manufacturers, and other components from other sole source and long
lead time vendors.

                                        8
<PAGE>   13

      Any alternate suppliers for our key components might not meet our quality
standards for component vendors. In the event of a reduction or interruption of
supply, as much as six months could be required before we would begin receiving
adequate supplies from alternative suppliers, if any. It is possible that a
source may not be available for us or be in a position to satisfy our production
requirements at acceptable prices and on a timely basis, if at all. In addition,
the manufacture of some of our long lead time and sole source components is
extremely complex, and our reliance on the suppliers of these components exposes
us to potential production difficulties and quality variations, which could
negatively impact the cost and timely delivery of our products. Any significant
interruption in the supply, or degradation in the quality, of any component
could have a material adverse effect on our business.

OUR FUTURE OPERATING RESULTS ARE DEPENDENT ON THE SALES OF A SINGLE PRODUCT

      We currently derive substantially all of our revenues from our broadband
point-to-multipoint wireless products and expect that this will continue for the
foreseeable future. The market may not continue to demand our current products,
and we may not be successful in marketing or developing any new or enhanced
products. Any reduction in the demand for our current products or our failure to
successfully develop, market and introduce new or enhanced products could
adversely affect our business. Factors that could affect sales of our current or
new or enhanced products include:

        - the demand for broadband point-to-multipoint wireless solutions;

        - our development and introduction of, and the market acceptance of, new
          and enhanced products that address customer requirements;

        - product introductions or announcements by our competitors;

        - price competition in our industry and among competing broadband access
          technologies, including leased line pricing; and

        - technological change.

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

      The communications market is characterized by rapid technological
advances, evolving industry and regulatory standards, changes in end-user
requirements, frequent new product introductions and evolving offerings by
service providers. We believe our future success will depend, in part, on our
ability to anticipate and adapt to these changes and to offer on a timely basis
new products and product features that meet customer demands. Furthermore, in
order to compete in many markets, we will have to develop different versions of
our existing products that operate at different frequencies and comply with
diverse, new or varying governmental regulations in each market. Our ability to
develop on a timely basis new products or enhancements and interfaces to
existing products, or the failure of new products, enhancements or interfaces to
achieve market acceptance, could adversely affect our business.

WE MUST DEVELOP PRODUCTS THAT ARE COMPLIANT WITH A VARIETY OF STANDARDS AND WORK
WITH DIFFERENT SPECTRUM ALLOCATION SCHEMES AND OTHER REGULATORY REQUIREMENTS.
FAILURE TO COMPLY WITH THESE STANDARDS WILL ADVERSELY AFFECT OUR ABILITY TO
INTRODUCE NEW PRODUCTS OR SELL EXISTING PRODUCTS

      Many countries require communications equipment used in their country to
comply with specific regulations, including safety regulations. In addition,
broadband wireless equipment must work with diverse spectrum allocation schemes
of many different countries, and some of these countries have not completed
their spectrum allocation process. We cannot predict what these regulations or
spectrum allocation schemes will be, nor when they will be completed, and we
cannot assure you that we will be able to comply with these regulations or
requirements. In addition, we have not completed all activities necessary to
comply with existing regulations and requirements in most of the countries in
which we intend to sell our products. Failure of our products to comply, or
delays in compliance, with the various existing and evolving industry
regulations and standards could delay the introduction or hinder the sale of our
products.
                                        9
<PAGE>   14

If this compliance proves to be more expensive or time-consuming than we
anticipate, our business would be adversely affected.

IF WE EXPERIENCE DIFFICULTIES OR DELAYS IN DEVELOPING NEW PRODUCTS, WE MIGHT
INCUR SIGNIFICANT UNEXPECTED EXPENSES OR REDUCED REVENUES

      We intend to continue to invest in product and technology development. The
development of new or enhanced products is a complex and uncertain process
requiring the accurate anticipation of technological and market trends. We may
experience design or manufacturing difficulties that could delay or prevent our
development, introduction or marketing of new products and enhancements, any of
which could cause us to incur unexpected expenses or lose revenues.

WE DEPEND ON REVENUES FROM INTERNATIONAL SALES. IF WE ARE UNABLE TO MANAGE OUR
INTERNATIONAL OPERATIONS EFFECTIVELY, OUR BUSINESS WOULD BE ADVERSELY AFFECTED

      Sales in foreign countries accounted for 76% of our revenues in 1998 and
49% in the three months ended March 31, 1999. In addition, most equipment
purchased by domestic customers has been shipped to international service
providers. International operations are subject to a number of risks and
uncertainties, including:

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

        - unexpected changes in regulatory requirements;

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

        - inadequate protection of intellectual property in some countries;

        - increased difficulty in collecting delinquent or unpaid accounts;

        - potentially adverse tax consequences;

        - the difficulties and costs of staffing and managing international
          operations;

        - political and economic instability; and

        - currency fluctuations.

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

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS, AND OUR REVENUES FLUCTUATE ACCORDING
TO THE TIMING AND SIZE OF THESE CUSTOMERS' ORDERS

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

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

        - the product requirements of these customers;

        - the financial and operational success of these customers; and

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

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

                                       10

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

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

IF THE MARKET FOR BROADBAND ACCESS DOES NOT CONTINUE TO GROW, THERE MAY BE A
LIMITED MARKET FOR OUR PRODUCTS

      The commercial market for products designed for broadband access has only
recently begun to develop, and our success will depend in large part on the
increased need for high-speed access networks and the continuation of broadband
spectrum allocations worldwide. Critical issues concerning the increased use of
broadband access services, including reliability, cost, ease of access, quality
of service and security, remain unresolved and may limit the market for our
products. As a result, the future growth rate, if any, or the ultimate size of
the market for our products cannot be accurately predicted.

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

      The market for broadband access products generally, and
point-to-multipoint wireless access products specifically, is rapidly evolving
and highly competitive. As a provider of broadband point-to-multipoint wireless
access products, we compete with several large telecommunications equipment
suppliers such as Alcatel, Bosch, Ericsson, Hughes, Newbridge, Nortel and
Spectrapoint, a newly formed joint venture between Cisco and Motorola, as well
as with smaller start-up companies. In addition, well capitalized companies such
as Nokia are potential entrants into the market. As an industry, broadband
point-to-multipoint wireless access products compete with other potential
broadband access solutions, such as wireless point-to-point technologies and
broadband satellite, wireline technologies that utilize existing infrastructure,
such as digital subscriber line, or DSL, fiber optic cable, cable modem
technologies and leased lines.

      We expect our competitors to continue to improve the performance of their
current products and introduce new products or new technologies as industry
standards and customer requirements evolve that may supplant or provide lower
cost alternatives to our products. Successful new product introductions or
enhancements by our competitors could reduce sales or the market acceptance of
our products, perpetuate intense price competition or make our products
obsolete. To be competitive, we must continue to invest significant resources in
research and development, sales and marketing and customer support. We cannot be
sure that we will have sufficient resources to make these investments or that we
will be able to make the technological advances necessary to be competitive. As
a result, we may not be able to compete effectively against our competitors. Our
failure to maintain and enhance our competitive position within the market may
adversely affect our business. Some of the factors on which we compete are:

          - availability of product

          - availability of financing

          - reliability of product

          - low entry price point

          - ability to scale

          - ease of use

          - bandwidth of product

          - operating experience

          - price-performance

          - breadth of frequency offerings

          - completeness of integration

          - customer support

          - multi-service capability

          - manufacturing capacity

          - network management software

          - installed base
                                       11
<PAGE>   16

      Increased competition is likely to result in price reductions, shorter
product life cycles, reduced gross margins, longer sales cycles and loss of
market share, any of which would adversely affect our business.

CHANGES IN REGULATIONS AFFECTING THE COMMUNICATIONS INDUSTRY COULD REDUCE THE
DEMAND FOR OUR PRODUCTS OR REQUIRE US TO MAKE EXPENSIVE MODIFICATIONS TO OUR
PRODUCTS

      Any changes to legal requirements relating to the communications industry,
including the adoption by international, federal or state regulatory authorities
of new laws or regulations, legal challenges to existing laws or regulations, or
a reversal of the trend toward deregulation, could have an adverse effect on the
market for our products. Moreover, service providers may require us, or we may
otherwise deem it necessary or advisable, to modify our products to address
actual or anticipated changes in the regulatory environment. Our inability to
modify our products or address any regulatory changes could have an adverse
effect on our business.

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

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

IF WE FAIL TO MANAGE OUR GROWTH, OUR BUSINESS WILL BE ADVERSELY AFFECTED

      During 1998, we increased the number of employees from 122 to 149. We
anticipate that further significant expansion, including opening additional
sales locations, will be required to address any future growth. We may not be
able to implement management information and control systems in an efficient and
timely manner, and our current or planned personnel, systems, procedures and
controls may not be adequate to support our future operations. If we are unable
to manage growth effectively, our business will be adversely affected. To manage
the expected growth of our operations and personnel, we will be required to:

        - improve financial and operational controls, and reporting systems and
          procedures;

        - install new management information systems; and

        - train, motivate and manage our sales and marketing, engineering,
          technical and customer support employees.

OUR LIMITED ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY MAY ADVERSELY AFFECT
OUR BUSINESS

      Our success and ability to compete is dependent in part on our proprietary
technology. Any infringement of our proprietary rights could result in
significant litigation costs, and any failure to adequately protect our
proprietary rights could result in our competitors offering similar products,
potentially resulting in loss of a competitive advantage and decreased revenues.
We rely on a combination of patent, copyright, trademark and trade secret laws,
as well as confidentiality agreements and licensing arrangements, to establish
and protect our proprietary rights. We presently have two issued U.S. patents
and two patent applications pending. Despite our efforts to protect our
proprietary rights, existing patent, copyright, trademark and trade secret laws
afford only limited protection. In addition, the laws of some
                                       12
<PAGE>   17

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

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

      The communications industry is characterized by the existence of a large
number of patents and frequent litigation based on allegations of patent
infringement. From time to time, third parties may assert patent, copyright,
trademark and other intellectual property rights to technologies and in various
jurisdictions that are important to our business. Any claims asserting that our
products infringe or may infringe proprietary rights of third parties, if
determined adversely to us, could have an adverse effect on our business. In
addition, in our agreements, we agree to indemnify our customers for any
expenses or liabilities resulting from claimed infringements of patents,
trademarks or copyrights of third parties. As the number of entrants in our
market increases and the functionality of our products is enhanced and overlaps
with the products of other companies, we may become subject to claims of
infringement or misappropriation of the intellectual property rights of others.
Any claims, with or without merit, could be time-consuming, result in costly
litigation, divert the efforts of our technical and management personnel, cause
product shipment delays or require us to enter into royalty or licensing
agreements, any of which could have an adverse effect on our operating results.
Royalty or licensing agreements, if required, may not be available on terms
acceptable to us, if at all. Legal action claiming patent infringement may be
commenced against us. We cannot assure you that we would prevail in this
litigation given the complex technical issues and inherent uncertainties in
patent litigation. In the event a claim against us was successful and we could
not obtain a license to the relevant technology on acceptable terms or license a
substitute technology or redesign our products to avoid infringement, our
business would be adversely affected.

IF WE, OUR SUPPLIERS, SYSTEM INTEGRATORS, RESELLERS OR SERVICE PROVIDERS FAIL TO
BE YEAR 2000 COMPLIANT, OUR BUSINESS MIGHT BE SEVERELY DISRUPTED

      The risk that software or hardware inaccurately process dates following
the Year 2000 presents several areas of risk for our business. In particular, we
are subject to:

        - costs associated with the failure of our products to be Year 2000
          compliant, including potential warranty or other claims from our
          customers, which may result in significant expense to us;

        - business shutdowns or slowdowns as a result of a failure of the
          internal management systems we use to run our business, which could
          disrupt our business operations;

        - interruption of product or component supplies, or a reduction in
          product quality, as a result of the failure of systems used by our
          suppliers; and

        - reductions or deferrals in sales activities as a result of Year 2000
          compliance issues of our distributors and system integrators.

CONTROL BY OUR EXISTING SHAREHOLDERS WILL LIMIT YOUR ABILITY TO INFLUENCE THE
OUTCOME OF MATTERS REQUIRING SHAREHOLDER APPROVAL AND COULD DISCOURAGE POTENTIAL
ACQUISITIONS OF OUR BUSINESS BY THIRD PARTIES

      Upon completion of this offering, our executive officers, directors and 5%
or greater shareholders and their affiliates will own 22,122,389 shares or
approximately __% of the outstanding shares of common stock. These shareholders,
if acting together, would be able to control all matters requiring approval by

                                       13
<PAGE>   18

shareholders, including the election of directors and the approval of mergers or
other business combination transactions. This concentration of ownership could
have the effect of delaying or preventing a change in our control or otherwise
discouraging a potential acquirer from attempting to obtain control of us, which
in turn could have an adverse effect on the market price of our common stock or
prevent our shareholders from realizing a premium over the market price for
their shares of common stock.

OUR ARTICLES OF INCORPORATION AND BYLAWS MAY DISCOURAGE POTENTIAL ACQUISITIONS
OF OUR BUSINESS BY THIRD PARTIES

      Some provisions of our Articles of Incorporation and Bylaws and of
California law may discourage, delay or prevent a merger or acquisition that a
shareholder may consider favorable. These provisions include:

        - authorizing the board to issue additional preferred stock;

        - prohibiting cumulative voting in the election of directors;

        - limiting the persons who may call special meetings of shareholders;

        - establishing a classified board of directors;

        - prohibiting shareholder actions by written consent; and

        - establishing advance notice requirements for nominations for election
          to the board of directors or for proposing matters that can be acted
          on by shareholders at shareholder meetings.

SUBSTANTIAL NUMBERS OF SHARES OF OUR COMMON STOCK WILL BECOME AVAILABLE FOR SALE
IN THE PUBLIC MARKET SIMULTANEOUSLY, WHICH COULD CAUSE THE MARKET PRICE OF OUR
STOCK TO DECLINE

      Sales of substantial amounts of common stock in the public market
following this offering, or the appearance that a large number of shares is
available for sale, could cause the market price of our common stock to decline.
The number of shares of common stock available for sale in the public market
will be limited by lock-up agreements under which the holders of substantially
all of our outstanding shares of common stock and options and warrants to
purchase common stock will agree not to sell or otherwise dispose of any of
their shares for a period of 180 days after the date of this prospectus without
the prior written consent of Merrill Lynch. However, Merrill Lynch may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to lock-up agreements. In addition to the adverse effect
a price decline could have on holders of common stock, that decline would likely
impede our ability to raise capital through the issuance of additional shares of
common stock or other equity securities.

PURCHASERS IN THIS OFFERING WILL SUFFER IMMEDIATE, SUBSTANTIAL DILUTION IN NET
TANGIBLE BOOK VALUE PER SHARE

      Because our common stock has in the past been sold at prices substantially
less than the initial public offering price that you will pay, you will suffer
immediate dilution of $     per share in pro forma net tangible book value. The
exercise of outstanding options and warrants is likely to result in further
dilution.

WE MAY NOT BE ABLE TO OBTAIN ADDITIONAL CAPITAL TO FUND OUR OPERATIONS ON
REASONABLE TERMS

      Our capital requirements depend on several factors, including the rate of
market acceptance of our products, the ability to expand our distribution and
customer base, the growth of sales and marketing expenses and other factors. If
capital requirements vary from those currently planned, we may require
additional financing sooner than anticipated. If we raise additional funds
through the issuance of equity securities, the percentage ownership of our
shareholders will be reduced, shareholders may experience additional dilution,
or these equity securities may have rights, preferences or privileges senior to
those of the holders of our common stock. If we raise additional funds through
the issuance of debt securities, those securities would have rights, preferences
and privileges senior to holders of common stock and the
                                       14
<PAGE>   19

terms of this debt could impose restrictions on our operations. Additional
financing may not be available when needed on terms favorable to us or at all.
If adequate funds are not available or are not available on acceptable terms, we
may be unable to develop or enhance our services, take advantage of future
opportunities or respond to competitive pressures, which could adversely affect
our business.

OUR STOCK PRICE MAY BE VOLATILE AND YOU MAY BE UNABLE TO RESELL YOUR SHARES AT
OR ABOVE THE OFFERING PRICE

      There previously has not been a public market for our common stock. We
cannot predict the extent to which investor interest in us will lead to the
development of a trading market or how liquid that market might become. The
initial public offering price for the shares will be determined by negotiations
between us and the representatives of the underwriters and may not be indicative
of prices that will prevail in the trading market. The trading price of our
common stock could be subject to wide fluctuations in response to factors such
as:

        - actual or anticipated variations in quarterly operating results;

        - announcements of technological innovations;

        - new products or services announced or offered by us or our
          competitors;

        - changes in financial estimates by securities analysts;

        - announcements of significant acquisitions, strategic partnerships,
          joint ventures or capital commitments by us or our competitors;

        - additions or departures of key personnel;

        - sales of common stock; and

        - other events or factors, many of which are beyond our control.

      In addition, the stock market in general, and the Nasdaq National Market
and stocks of technology companies in particular, have experienced extreme price
and volume fluctuations that have often been unrelated or disproportionate to
the operating performance of these companies. Broad market and industry factors
may adversely affect the market price of our common stock, regardless of our
actual operating performance. In the past, following periods of volatility in
the market price of a company's securities, securities class-action litigation
has often been initiated against these companies. This litigation, if initiated,
could result in substantial costs and a diversion of management's attention and
resources, which would adversely affect our business.

                           FORWARD-LOOKING STATEMENTS

      This prospectus includes forward-looking statements. We have based these
forward-looking statements on our current expectations and projections about
future events. These forward-looking statements are subject to risks,
uncertainties and assumptions about us, including:

        - uncertainty regarding the commercial acceptance of broadband wireless
          technologies;

        - uncertainty regarding our future operating results;

        - our ability to introduce new products;

        - delays or losses of sales due to long sales and implementation cycles
          for our products;

        - the possibility of lower prices, reduced gross margins and loss of
          market share due to increased competition; and

        - increased demands on our resources due to anticipated growth.

      In light of these risks, uncertainties and assumptions, the
forward-looking events discussed in this prospectus might not occur. We
undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information or future events.

                                   TRADEMARKS

      Each trademark, trade name or service mark appearing in this prospectus
belongs to its holder. AirView and AirMAN are our registered trademarks.

                                USE OF PROCEEDS

      We estimate our net proceeds from the sale of the      shares of our
common stock offered in this offering to be approximately $     million, or
approximately $     million if the underwriters' over-allotment option is
exercised in full, based on an assumed initial public offering price of $
per share and after deducting the estimated underwriting discount and offering
expenses.

      We intend to use the net proceeds from this offering for general corporate
purposes, including research and development, expansion of our sales and
marketing organizations and working capital. Pending these uses, we intend to
invest the net proceeds from this offering in short-term, investment-grade,
interest-bearing securities.

                                DIVIDEND POLICY

      We have never paid cash dividends on our common stock. We currently intend
to retain any future earnings to fund the development and growth of our
business. Therefore, we do not currently anticipate paying any cash dividends in
the foreseeable future. In addition, pursuant to our loan agreement with Silicon
Valley Bank and subject to limited exceptions, we may not pay dividends on our
capital stock so long as obligations are outstanding under the loan agreement or
for so long as Silicon Valley Bank has any commitment to make advances to us
under the loan agreement.

                                 CAPITALIZATION

      The following table summarizes our capitalization as of March 31, 1999 as
follows:

        - on an actual basis;

        - on a pro forma basis to give effect to the conversion of all
          outstanding shares of our preferred stock into common stock; and

        - on a pro forma, as adjusted basis to reflect the application of the
          net proceeds from our initial public offering and the conversion of
          all outstanding shares of our preferred stock into common stock.

          outstanding as of March 31, 1999 at a weighted average exercise price
          of $1.68 per share; and

                                    DILUTION

      As of March 31, 1999, our net tangible book value was approximately $18.9
million, or $0.50 per share of common stock, after giving effect to the
conversion of all outstanding shares of our preferred stock into common stock.
Net tangible book value represents the total amount of our tangible assets less
total liabilities divided by the number of shares of common stock outstanding.
Without taking into account any other changes in net tangible book value after
March 31, 1999, other than to give effect to the receipt by us of the net
proceeds from the sale of the      shares of common stock in this offering at an
assumed initial public offering price of $     per share, our pro forma net
tangible book value as of March 31, 1999 would have been approximately $     ,
or $     per share. This represents an immediate increase in net tangible book
value of $     per share to existing shareholders and an immediate dilution of
$     per share to new investors purchasing shares in this offering. The
following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      This section contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ substantially from those
anticipated in these forward-looking statements as a result of many factors,
including those set forth under "Risk Factors" and elsewhere in this prospectus.
The following discussion should be read together with our consolidated financial
statements and related notes included elsewhere in this prospectus.

OVERVIEW

      We are a leading provider of intelligent broadband wireless access systems
to competitive communications service providers worldwide. We were incorporated
in 1994 and introduced our first product, the AirMAN point-to-point system, in
1996. AirMAN was discontinued in September 1998 because the market for
high-capacity point-to-point broadband wireless access systems did not develop
as we had expected. From 1996 onward, substantially all of our product
development efforts were devoted to the AirStar point-to-multipoint broadband
wireless access system. The first AirStar beta systems were shipped in the third
quarter of 1998.

      All of our 1996 and 1997 revenues and approximately 47% of our 1998
revenues were derived from sales of the AirMAN system. Currently, our revenues
are generated from sales of AirStar systems through system integrators that
integrate our products, local resellers and our direct sales force. We began
initial sales of an early 26 GHz AirStar system in Europe in early 1998.
Subsequently, we introduced the AirStar system more widely to the European,
Latin American and Middle Eastern markets. For 1998 and the three months ended
March 31, 1999, international revenues represented approximately 76% and 49% of
total revenues. In addition, a substantial portion of our domestic revenues is
derived from systems intended for installation in international locations.

      Although we have historically assembled our products in-house, we are
currently in the process of outsourcing manufacturing and assembly to contract
manufacturers. We expect these contract manufacturers to be responsible for most
of our volume production in the future. Currently, we have contracts in place
with Solectron Corporation and Microelectronic Technologies, Inc. of Taiwan to
serve as our manufacturers.

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

      Revenues. Our current revenues primarily consist of product revenues from
the sale of the AirStar system. Revenues from product sales are generally
recognized when all of the following conditions are met: the product has
shipped, we have the right to invoice the customer, collection of the receivable
is probable and we have fulfilled all contractual obligations to the customer.

      Cost of Revenues. Our cost of revenues consists of contract manufacturing
costs, material costs, compensation costs, manufacturing overhead, warranty
reserves and other direct product costs.

      Research and Development. Research and development expenses consist of
compensation costs, the cost of certain software development tools, consultant
fees and prototype expenses related to the design, development and testing of
our products. Our policy is to expense all research and development expenses as
incurred. For certain projects we receive third-party research and development
funding, which is offset against the related expenses.

                                       21
<PAGE>   26

      Sales and Marketing. Sales and marketing expenses consist primarily of
compensation costs, commissions, travel and related expenses for marketing,
sales and field service support personnel, as well as product management, trade
show and promotional expenses.

      General and Administrative. General and administrative expenses consist
primarily of compensation costs and related expenses for executive, finance,
management information systems, human resources, and administrative personnel.
These expenses also include professional fees, facilities and other general
corporate expenses.

      Amortization of Deferred Stock Compensation. Amortization of deferred
stock compensation resulted from the granting of stock options to employees with
exercise prices per share determined to be below the estimated fair values per
share of our common stock at dates of grant. The deferred compensation is being
amortized to expense over the vesting period of the individual options,
generally four years. We have recorded total deferred stock compensation of $2.1
million through March 31, 1999.

      Other Income (Expense). Other income (expense) consists primarily of
interest income earned on low-risk, short-term investments and interest paid on
outstanding debt.

      Income Taxes. We have not recorded any provision for income taxes for any
of the periods presented because we have generated net losses since inception.

COMPARISON OF THREE MONTHS ENDED MARCH 31, 1998 AND 1999

      Revenues. Revenues increased 115% from $996,000 for the three months ended
March 31, 1998 to $2.1 million for the three months ended March 31, 1999. This
increase was primarily due to an increase in the number of sales of the 26 GHz
AirStar system and was partially offset by a decrease in sales of AirMAN
systems. Sales to three customers, Nortel, Pele-Phone and Italtel, represented
43%, 18% and 15% of revenues for the three months ended March 31, 1998. Sales to
two customers, Lucent and Italtel, represented 51% and 37% of revenues for the
three months ended March 31, 1999. Substantially all of the revenues for these
periods were generated from installations in international locations.

      Gross Profit. Gross profit increased from a loss of $314,000 for the three
months ended March 31, 1998 to a profit of $493,000 for the three months ended
March 31, 1999. This increase in gross profit was primarily due to lower unit
costs and lower labor costs associated with higher volume product sales and
greater product maturity of the AirStar system. Gross profit, as a percentage of
revenues, improved from negative 32% for the three months ended March 31, 1998
to 23% for the three months ended March 31, 1999. We anticipate that gross
profit will vary significantly from period to period until our sales and
production volumes stabilize.

      Research and Development. Research and development expenses decreased from
$4.3 million for the three months ended March 31, 1998 to $4.2 million for the
three months ended March 31, 1999, primarily due to the offset of $450,000 from
third-party research and development funding. This decrease was primarily the
result of the greater increase in revenues during the stated periods. Gross
research and development expenses increased from $4.3 million for the three
months ended March 31, 1998 to $4.7 million for the three months ended March 31,
1999. This increase was primarily due to an increase in our research and
development personnel, number of development projects and related third-party
design and consulting charges. These projects primarily consisted of the
development of the AirStar system at 26, 10 and 38 GHz.

      Sales and Marketing. Sales and marketing expenses increased from $1.1
million for the three months ended March 31, 1998 to $1.3 million for the three
months ended March 31, 1999. This increase was due to the continued expansion in
sales, technical assistance and field support personnel necessary to support
both the pre-sale and post-sale activities associated with the AirStar system.
Increased spending includes compensation costs, travel and increased sales
commissions due to higher sales. Sales and marketing expenses, as a percentage
of revenues, decreased from 106% to 62%. This decrease was primarily due to a
greater increase in revenues during the stated periods.

                                       22
<PAGE>   27

      General and Administrative. General and administrative expenses increased
from $913,000 for the three months ended March 31, 1998 to $1.8 million for the
three months ended March 31, 1999. This increase was due to an increase in rent
expense resulting from additional office space assumed and an increase in
personnel. General and administrative expenses, as a percentage of revenues,
decreased from 92% to 82%. This decrease was primarily due to a greater increase
in revenues during the stated periods.

      Amortization of Deferred Stock Compensation. Amortization of deferred
compensation was $168,000 for the three months ended March 31, 1999. This
amortization is due to deferred compensation of approximately $2.1 million,
related to stock options granted in the year ended December 31, 1998 and the
three months ended March 31, 1999, which we are amortizing over the vesting
periods of the applicable options beginning in 1999.

      Other Income (Expense). Other income decreased from $218,000 for the three
months ended March 31, 1998 to an expense of $39,000 for the three months ended
March 31, 1999. This decrease was primarily due to less interest earned on lower
average cash balances, and interest expense incurred due to greater utilization
of secured equipment loans and lease and bank financing for working capital.

COMPARISON OF YEARS ENDED DECEMBER 31, 1996, 1997 AND 1998

      Revenues. Revenues increased from $731,000 in 1996 to $5.6 million in 1997
due to increased sales of AirMAN in 1997 after its introduction in late 1996.
Revenues decreased from $5.6 million in 1997 to $5.4 million in 1998. This
decrease was primarily due to the discontinuation of the AirMAN system, which
resulted in declining revenues that more than offset the revenues generated from
the launch of the AirStar system. Sales to two customers, PanDacom and o.tel.o
Communications GmbH, represented 79% and 12% of revenues for 1996. Sales to four
customers, PanDacom, Pele-Phone, o.tel.o and Alpine-Energie, represented 39%,
21%, 20% and 12% of revenues for 1997. PanDacom resold substantially all of its
purchases to o.tel.o in 1996 and 1997. Sales to four customers, Alpine-Energie,
Lucent, Italtel and Pele-Phone, represented 27%, 16%, 15% and 10% of revenues
for 1998. Substantially all of the revenues for these years were generated from
installations in international locations.

      Gross Profit (Loss). Gross profit decreased from $112,000 in 1996 to a
loss of $2.7 million in 1997 due to sales discounts and inventory write-downs
related to the AirMAN system. Gross profit decreased from a loss of $2.7 million
in 1997 to a loss of $4.2 million in 1998. This decrease was primarily due to
pricing pressures for the AirMAN system in the point-to-point equipment market
and increased warranty reserves for the AirMAN system.

      Research and Development. Research and development expenses increased from
$10.4 million in 1996 to $15.3 million in 1997 and $16.1 million in 1998. The
increases in research and development expenses were primarily due to increases
in personnel and compensation costs, prototype material expenses, third party
engineering charges and expenses related to the beta release of the initial
AirStar system. Gross research and development expenses increased from $15.3
million in 1997 to $17.0 million in 1998. Gross research and development
expenses in 1998 were partially offset by third-party research and development
funding of $900,000.

      Sales and Marketing.  Sales and marketing expenses increased from $1.3
million in 1996 to $3.8 million in 1997 and $4.8 million in 1998. These
increases were primarily due to the significant expansion in sales, technical
assistance and field support personnel necessary to support both the pre-sale
and post-sale activities associated with the AirStar system. Increased spending
also included compensation costs, travel and increased sales commissions due to
higher sales.

      General and Administrative.  General and administrative expenses increased
from $1.2 million in 1996 to $3.5 million in 1997 and $4.0 million in 1998. The
increases in 1997 and 1998 were primarily due to increased rent expense due to
relocation to larger facilities, as well as an increase in personnel.

      Other Income (Expense).  Other income increased from $643,000 in 1996 to
$703,000 in 1997 and decreased to $304,000 in 1998. In 1997, interest earned
increased due to higher average cash balances year

                                       23
<PAGE>   28

to year. The decrease in 1998 was primarily due to interest expense resulting
from greater utilization of secured equipment loans and lease and bank financing
for working capital.

QUARTERLY RESULTS OF OPERATIONS

      The following tables present unaudited quarterly operating results, in
dollars and as a percentage of revenues, for the five quarters ended March 31,
1999. We believe this information reflects all adjustments (consisting only of
normal recurring adjustments) that we consider necessary for a fair presentation
of such information in accordance with generally accepted accounting principles.
The results for any quarter are not necessarily indicative of results for any
future period.

      Revenues increased for the two quarters ended March 31 and June 30, 1998
due to increased sales volumes driven by AirMAN system discounts. During these
quarters, revenues also increased due to

                                       24
<PAGE>   29

AirStar system sales to customers for our pre-beta testing program. Revenues
decreased for the quarter ended September 30, 1998 primarily due to the
discontinuation of the AirMAN system. Revenues increased for the quarters ended
December 31, 1998 and March 31, 1999 due to AirStar system sales following our
beta release. Gross profit increased for the quarters ended September 30, 1998,
December 31, 1998 and March 31, 1999 primarily due to increased sales of AirStar
products at relatively higher profit margins. Research and development expenses
decreased in the quarter ended December 31, 1998 primarily due to third-party
engineering funding and fluctuations in third-party design and consulting
charges and usage of prototype material. Sales and marketing expenses fluctuate
on a quarterly basis due to seasonal promotional and marketing expenses for
trade shows. General and administrative expenses increased in the quarter ended
March 31, 1999 due to an increase in rent expense resulting from additional
office space assumed and an increase in personnel. Other income decreased for
the quarters ended June 30, September 30 and December 31, 1998 primarily due to
an increase in interest expense as a result of greater utilization of secured
equipment loans and lease financing and bank financing for working capital.

      We believe that period-to-period comparisons of our operating results are
not necessarily meaningful. You should not rely on them to predict future
performance. The amount and timing of our operating expenses generally may
fluctuate significantly in the future as a result of a variety of factors. We
face a number of risks and uncertainties encountered by early stage companies,
particularly those in rapidly evolving markets such as the telecommunications
and data communications equipment industries. We may not be able to successfully
address these risks and difficulties. In addition, although we have experienced
revenue growth recently, our revenue growth may not continue, and we may not
achieve or maintain profitability in the future.

      Our quarterly and annual operating results have fluctuated in the past and
are likely to fluctuate significantly in the future due to a variety of factors,
many of which are outside of our control. Our operating results to date are
largely based on sales of AirMAN and customer trials of AirStar. It is likely
that in some future quarter our operating results may fall below the
expectations of securities analysts and investors. In this event, the trading
price of our common stock could significantly decline.

      Some of the factors that could affect our quarterly or annual operating
results include:

        - our ability to attain and maintain production volumes and quality
          levels for our products;

        - our ability to obtain sufficient supplies of sole source or long lead
          time components for our products;

        - our ability to achieve cost reductions;

        - the size, timing and frequency of network buildouts, which are
          typically large and infrequent;

        - the timing and amount of, or cancellation or rescheduling of, orders
          for our products, particularly large orders from our system
          integrators and resellers;

        - our ability to develop, introduce, ship and support new products and
          product features and to manage product transitions; and

        - a decrease in the average selling prices of our products.

      Our sales cycle, which is lengthy -- typically between six and twelve
months -- contributes to fluctuations in our quarterly operating results.
Further, the emerging and evolving nature of the market for point-to-multipoint
systems may lead prospective customers to postpone their purchasing decisions.
In addition, general concerns regarding Year 2000 compliance may further delay
purchase decisions by prospective customers.

      Most of our expenses, such as employee compensation and lease payments for
facilities and equipment, are relatively fixed in the near term. In addition,
our expense levels are based, in part, on our expectations regarding future
revenues. As a result, any shortfall in revenues relative to our expectations
could cause significant changes in our operating results from quarter to
quarter. Due to the foregoing

                                       25
<PAGE>   30

factors, we believe period-to-period comparisons of our revenue levels and
operating results are not meaningful. You should not rely on our quarterly
revenues and operating results to predict our future performance.

LIQUIDITY AND CAPITAL RESOURCES

      Since inception, we have financed our operations primarily through the
sale of preferred equity securities and more recently through the use of secured
loans and leases for the purchase of capital equipment and bank financing for
working capital. As of March 31, 1999, we have raised an aggregate of $93.1
million, before offering expenses of $200,000, through the sale of preferred
stock.

      As of March 31, 1999, cash and cash equivalents were $8.0 million and
short-term investments were $14.9 million. We have a $6.0 million bank line of
credit. As of March 31, 1999, borrowings outstanding were $2.9 million and
amounts utilized for outstanding letters of credit were $500,000 under this
agreement. The line of credit is secured by eligible outstanding accounts
receivable and inventory. The borrowings under the line are due in January 2000
and accrue interest at the 30-day LIBOR plus 2.25% or the bank's prime rate, at
our option. In addition, we have secured equipment financing with three lenders
which allows a maximum borrowing of $11.8 million of which $2.0 million was
available as of March 31, 1999. As of March 31, 1999, $7.0 million remained
outstanding under these arrangements. See note 6 of notes to consolidated
financial statements.

      Cash used for operations was $5.0 million for the three months ended March
31, 1999 and $25.9 million for fiscal 1998. Cash used for operations for both
periods was primarily due to the net loss, partially offset by non-cash charges.

      Cash used in investing activities was $6.4 million for the three months
ended March 31, 1999, primarily due to excess cash invested in short-term
investments. Cash used in investing activities was $2.2 million for fiscal 1998,
primarily for capital equipment purchases.

      Cash provided by financing activities was $13.3 million for the three
months ended March 31, 1999. Cash provided by financing activities was $18.5
million for fiscal 1998. Cash provided by financing activities for both periods
was primarily due to issuance of preferred stock and, to a lesser extent,
capital lease and bank financing.

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

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

      We believe that continued substantial investment in research and
development is critical to attaining our strategic product and cost-reduction
objectives. We also expect to expand our field sales and customer support
organizations as customers move from trials to large scale deployments, which
will in turn increase sales and marketing expenses. The growth of our business
and operation as a public company will require additional personnel and costs
resulting in increases in our general and administrative expenses.

      We believe that the net proceeds from this offering together with our cash
and cash equivalents balances, short-term investments and funds available under
our existing line of credit will be sufficient to

                                       26
<PAGE>   31

satisfy our cash requirements for at least the next 12 months. Our management
intends to invest our cash in excess of current operating requirements in
short-term, interest-bearing, investment-grade securities.

IMPACT OF YEAR 2000

      Many currently installed computer systems and software products are coded
to accept only two-digit entries in date code fields. Beginning in the year
2000, these date code fields will need to accept four-digit entries to
distinguish 21st century dates from 20th century dates. Any of our computer
programs or hardware that have date-sensitive software or embedded chips and
have not been upgraded to comply with these "year 2000" requirements may
recognize a date using "00" as the year 1900 rather that the year 2000. This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar normal business activities.

      General Readiness Assessment.  The year 2000 problem affects the
computers, software and other equipment that we use, operate or maintain for our
operations. As a result, we have formalized our year 2000 compliance plan, to be
implemented by a team of our internal information technology staff responsible
for monitoring the assessment and remediation status of our year 2000 projects
and reporting that status to our executive staff. This project team is currently
assessing the potential effect and costs of remediating the year 2000 problem
for our internal systems. To date, we have not obtained verification or
validation from any independent third parties of our processes to assess and
correct any of our year 2000 problems or the costs associated with these
activities.

      Assessment of Netro's Products.  Beginning in 1998, we began assessing the
ability of our products to operate properly in the year 2000. We believe that
our current products are year 2000 compliant, other than software used in our
AirMAN product. We are in the process of notifying all of our customers that are
using our AirMAN product that we have a software upgrade that fixes the
non-compliant software. Additionally, as we design and develop new products, we
subject them to testing for year 2000 compliance and the ability to distinguish
between various date formats. We expect to continue to test our software and
products for year 2000 compliance and compliance when used with other standard
operating systems or computer platforms. Accordingly, we do not believe that the
year 2000 issue presents a material exposure as it relates to our products

      Assessment of Internal Infrastructure.  We believe that we have identified
most of the major computers, software applications and related equipment used in
connection with our internal operations that will need to be evaluated to
determine if they must be modified, upgraded or replaced to minimize the
possibility of a material disruption to our business. Based on a review of our
computer systems, we have determined that we will be required to modify or
replace some portions of our software so that those systems will properly
utilize dates beyond December 31, 1999. We presently believe that with
modifications or replacements of existing software through our maintenance
contracts with third-party vendors, year 2000 issues can be mitigated. We expect
to complete this process before December 31, 1999.

      Systems Other than Information Technology Systems.  In addition to
computers and related systems, the operation of office and facilities equipment,
such as fax machines, telephone switches, security systems and other common
devices, may be affected by the year 2000 problem. We are currently assessing
the potential effect and costs of remediating the year 2000 problem on our
office equipment and our facilities in San Jose, California. We expect to
complete this process before December 31, 1999.

      Costs of Remediation.  We estimate the total cost to us of completing any
required modifications, upgrades or replacements of our internal systems will
not exceed $100,000, most of which we expect to incur during calendar 1999. This
estimate is being monitored, and we will revise it as additional information
becomes available. Based on the activities described above, we do not believe
that the year 2000 problem will have a material adverse effect on our business
or operating results. In addition, we have not deferred any material information
technology projects nor equipment purchases as a result of our year 2000 problem
activities.

                                       27
<PAGE>   32

      Suppliers.  As part of our year 2000 plan, we have contacted third-party
suppliers of components and key subcontractors used in the delivery of our
products to identify and, to the extent possible, resolve issues involving the
year 2000 problem. However, we have limited or no control over the actions of
these third-party suppliers and subcontractors. Thus, while we expect that we
will be able to resolve any significant year 2000 problems with these third
parties, there can be no assurance that these suppliers will resolve any or all
year 2000 problems before the occurrence of a material disruption to the
operation of our business. Any failure on the part of these third parties to
timely resolve year 2000 problems with their systems in a timely manner could
have a material adverse effect on our business. We expect to complete this
process before December 31, 1999.

      Most Likely Consequences of Year 2000 Problems.  We expect to identify and
resolve all year 2000 problems that could materially adversely affect our
business operations before December 31, 1999. However, we believe that it is not
possible to determine with complete certainty that all year 2000 problems
affecting us have been identified or corrected. The number of devices and
systems that could be affected and the interactions among these devices and
systems are too numerous to address. In addition, no one can accurately predict
which year 2000 problem-related failures will occur or the severity, timing,
duration or financial consequences of these potential failures. As a result, we
believe that the following consequences are possible:

        - a significant number of operational inconveniences and inefficiencies
          for us, our contract manufacturers and our customers that will divert
          management's time and attention and financial and human resources from
          ordinary business activities;

        - possible business disputes and claims, including claims under product
          warranty, due to year 2000 problems experienced by our customers and
          incorrectly attributed to our products or performance, which we
          believe will be resolved in the ordinary course of business; and

        - a few serious business disputes alleging that we failed to comply with
          the terms of contracts or industry standards of performance, some of
          which could result in litigation or contract termination.

      Contingency Plans:  We are currently developing contingency plans to be
implemented if our efforts to identify and correct year 2000 problems affecting
our internal systems are not effective. We expect to complete our contingency
plans before December 31, 1999. Depending on the systems affected, these plans
could include:

        - accelerated replacement of affected equipment or software;

        - short- to medium-term use of backup equipment and software or other
          redundant systems;

        - increased work hours for our personnel or the hiring of additional
          information technology staff; and

        - the use of contract personnel to correct, on an accelerated basis, any
          year 2000 problems that arise or to provide interim alternate
          solutions for information system deficiencies.

      Our implementation of any of these contingency plans could have a material
adverse effect on our business.

      Disclaimer:  The discussion of our efforts and expectations relating to
year 2000 compliance are forward-looking statements. Our ability to achieve year
2000 compliance, and the level of incremental costs associated therewith, could
be adversely affected by, among other things, the availability and cost of
contract personnel and external resources, third-party suppliers' ability to
modify proprietary software and unanticipated problems not identified in the
ongoing compliance review.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      Foreign Currency Hedging Instruments.  We transact business in various
foreign currencies and, accordingly, we are subject to exposure from adverse
movements in foreign currency exchange rates. To

date, the effect of changes in foreign currency exchange rates on revenues and
operating expenses have not been material. Basically, all of our revenues are
earned in U.S. dollars. Operating expenses incurred by our German subsidiary are
denominated primarily in European currencies. We currently do not use financial
instruments to hedge these operating expenses. We intend to assess the need to
utilize financial instruments to hedge currency exposures on an ongoing basis.

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

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

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

                                    BUSINESS

      We are a leading provider of intelligent broadband wireless access systems
to competitive communications service providers worldwide. Our AirStar system
allows service providers to rapidly and cost effectively offer integrated voice
and high-speed packet data services to their business subscribers. We have
engineered AirStar to support broad service rollouts and to operate at a number
of different licensed frequencies worldwide. AirStar derives its
price-performance benefits from dynamic bandwidth allocation and an intelligent
point-to-multipoint architecture. We believe that AirStar is one of the first
commercially available broadband wireless access systems providing integrated
voice and high-speed data services using a point-to-multipoint architecture.

INDUSTRY BACKGROUND

      In recent years, the volume of high-speed data traffic across
communications networks worldwide has grown dramatically as the public Internet
and private corporate intranets have become essential for communications and
e-commerce. International Data Corporation forecasts that the number of Internet
users worldwide will grow from approximately 142 million in 1998 to
approximately 502 million by the end of 2003. In addition to an increase in
network traffic volume resulting from this growing user base, traffic is also
increasing due to the development of sophisticated multimedia content and the
deployment of bandwidth-consuming network applications such as e-commerce. IDC
estimates that by 2003, 87% of worldwide e-commerce revenue will be generated
from business users or business-to-business transactions. These forms of content
and network applications require the transmission of large, bandwidth-intensive
files across networks. As users increasingly rely on higher-bandwidth network
applications and content for business and personal use, they require
cost-effective broadband network access, which is often unavailable or
inadequate over the legacy wireline access network infrastructure.

      Telecommunications deregulation worldwide is creating greatly expanded
opportunities for a larger group of service providers to meet the increasing
demand for broadband network access. Increased deregulation has enabled a large
number of CLECs to provide local network access historically only offered by the
incumbent, often monopolistic, provider in a given geographical region. This
opportunity is increasingly global as Europe, Latin America and Japan join the
U.S. and the United Kingdom in promoting a competitive local access environment.
Many of these CLECs are focusing on the deployment of wireless broadband
networks because of the inherent ability of wireless technology to offer service
quickly to a large number of subscribers. Furthermore, regulators and local
service providers are focused on wireless broadband as a key technology enabler
for future broadband networks, especially in countries where existing wireline
infrastructure quality would require substantial investment to carry broadband
services. The Strategis Group estimates that wireless broadband, defined as
licensed frequencies from 2.5 to 43 GHz, has the potential to address 60% of the
metropolitan broadband business services market.

      In order to enable greater local competition and accelerate broadband
deployments, the FCC and similar regulators abroad have recently opened up
various bands of wireless spectrum at frequencies of 10 GHz and above. These
frequency bands have been allocated or awarded in large contiguous blocks and
have the potential to support both broadband data and traditional voice
services, unlike some lower frequency bands used for narrowband mobile
telephony. To obtain the rights to these licensed bands, many service providers
have either paid substantial upfront fees, committed to large capital
deployments for wireless network buildouts or acquired companies that own
broadband spectrum. Additionally, some mobile telephony operators are seeking to
leverage their wireless experience, roof rights and backhaul infrastructure by
acquiring spectrum to deploy broadband services in what is called fixed mobile
integration, or FMI. These spectrum acquisitions have given CLECs and mobile
operators an alternative means to provide broadband services.

      Although increased demand and deregulation have generated new
opportunities for service providers using both wireline and wireless networks,
bandwidth limitations of the "last mile" have constrained service providers from
exploiting these opportunities. The last mile generally spans the link between
the network backbone and the subscriber. Although many wide area network
backbones have been upgraded

                                       30
<PAGE>   35

with fiber and have utilized technologies to operate at speeds up to 9 gigabits
per second, the local access telephone network typically consists of legacy
copper lines originally designed to transmit constant-rate voice at a fraction
of that speed. This access bottleneck is frustrating a broad base of business
users, many of which require symmetrical access to high-speed data that tends to
be bursty.

      Wireline technologies attempt to solve these bandwidth constraints, but
they do not meet the needs of many CLECs that are seeking to offer broadband
services to businesses worldwide. DSL and cable modem services have recently
been launched by incumbent owners of copper or coaxial cable infrastructures, or
by selected CLECs in the U.S. that have been granted regulatory access to those
infrastructures. Most DSL and cable modem deployments, however, offer
high-speed, asymmetrical services or slower speed symmetrical services. In the
case of DSL, speeds can vary with distance and infrastructure quality. Neither
of these services satisfies the needs of many businesses that require access to
symmetrical high-speed data. Additionally, because coaxial cable passes more
residences than businesses, or is not deployed in many countries, it is not an
alternative for many business users worldwide. Leased lines are available to
business users in many countries, but the prices associated with these
dedicated, high-bandwidth lines are often prohibitive, especially outside the
U.S. Similarly, fiber optic technology is typically only deployed to solve the
bandwidth needs of the largest businesses, where high installation costs can be
spread over many users. In short, these wireline technologies are not
cost-effective for many businesses, or they require either substantial upfront
capital investment or a high-quality existing infrastructure.

      CLECs and mobile operators with licenses to broadband wireless spectrum
worldwide are now seeking to capitalize on deregulation and increased demand to
offer broadband network access to subscribers. Many of these CLECs target
business customers for which alternate broadband access technologies are
unavailable, inadequate or not cost-effective. Broadband wireless technologies
can offer immediate coverage of a metropolitan area and can be deployed rapidly
without dependence on the quality of or access to a legacy network.

      Although many CLECs with broadband wireless spectrum recognize the
opportunity to meet new demand for integrated voice and high-speed data
services, many are constrained from cost effectively offering these services to
a wide base of business users. Historically, most wireless broadband access
technologies were only cost-effective for providing a dedicated link to connect
high traffic nodes in a network such as large office buildings where high radio
costs can be spread over many users. These dedicated wireless links are
typically referred to as point-to-point connections.

      CLECs and mobile operators deploying broadband wireless networks today
must differentiate their services to a wide base of business users while
effectively competing with services offered by fiber, leased lines, DSL and
cable modems. For example, a CLEC deploying a wireless network could offer
multiple integrated voice and data services with guaranteed quality levels to
maximize revenue from its spectrum. A CLEC that could rapidly offer these
services to a broad base of business customers would often have an early-mover
advantage in a particular metropolitan market. Any broadband wireless solution
implemented by these CLECs must be reliable and cost-effective to deploy.
Although a large market opportunity exists to provide solutions that allow CLECs
to deploy differentiated services, very few vendors offer commercially available
wireless broadband products to serve this market.

THE NETRO SOLUTION

      We are a leading provider of intelligent broadband wireless access systems
to competitive communications service providers worldwide. Our AirStar system
allows service providers to rapidly and cost effectively offer integrated voice
and high-speed packet data services to their business subscribers. We have
engineered AirStar to support broad service rollouts and to operate at a number
of different licensed frequencies worldwide. AirStar derives its
price-performance benefits from dynamic bandwidth allocation and an intelligent
point-to-multipoint architecture. We believe that AirStar is one of the first
commercially available broadband wireless access systems providing integrated
voice and high-speed data services using a

                                       31
<PAGE>   36

point-to-multipoint architecture. We believe our AirStar system provides the
following benefits to service providers:

      Service Integration and Bandwidth on Demand.  Our AirStar system employs
our proprietary ATM-based media access control layer, CellMAC, which enables
flexible and dynamic sharing of bandwidth on a packet-by-packet basis among a
number of subscribers and service types. Many existing access network
implementations are optimized for either voice or data traffic. Voice traffic
requires constant, low capacity transmissions while data traffic requires
bursty, high-capacity transmissions. Consequently, network operators wishing to
carry both types of traffic often must set aside capacity to service peak data
traffic requirements, allow degradation of service during heavy usage or service
a smaller number of subscribers. In contrast, service providers using AirStar's
intelligent wireless transport can support voice and high-speed data from the
same system without these performance compromises. Additionally, AirStar allows
service providers to offer symmetrical broadband services, with burst rates up
to 8 Mbps to meet the needs of many business users that send and receive large
files for email, application hosting, intranet access and e-commerce.

      Cost-Effective Deployment and Operation.  AirStar's cost-effective
deployment allows a service provider to compete effectively in the broadband
access market. By employing a point-to-multipoint, hub-and-spoke architecture,
one AirStar hub radio can serve multiple subscriber radios, which lowers total
radio costs relative to point-to-point solutions. AirStar also uses a time
division multiple access, or TDMA, architecture, which reduces duplicate network
hardware components such as modems, and further lowers overall system costs. In
addition, a significant portion of the buildout of an AirStar network is
directly related to subscriber growth, resulting in success-based deployment of
capital. To deploy service to incremental subscribers in a sector, a provider
simply installs plug-and-play subscriber equipment at the business and
provisions the installation remotely. Finally, AirStar's statistical
multiplexing allows a service provider to optimize spectrum use and the
deployment of equipment by expanding effective transmission capacity.

      Quality of Service and Reliability.  Service providers using AirStar can
deploy voice and data services at different price points to different market
segments with the option for guaranteed quality of service levels and up to
99.999% availability. AirStar can prioritize transmissions based on different
traffic priority levels, and fill available transmission capacity with packets
of lower priority data traffic. Furthermore, AirStar's system is engineered to
enable competitive service providers to offer the same high reliability and
availability for all services that incumbent service providers have historically
offered for voice services. Reliability is accomplished through forward error
correction, redundancy and comprehensive network management software.

      Rapid Time to Market.  Service providers using AirStar can achieve rapid
time to market for integrated voice and high-speed data through AirStar's
efficient installation, end-to-end network management and intelligent wireless
transport. Competitive service providers that we target have typically committed
a high level of capital investment to enter the broadband access market, and
thus are focused on quickly realizing return on their investment. Our AirStar
system is scalable and allows service providers to rapidly offer new services to
existing or incremental subscribers within a cell by a simple software command
and a plug-and-play radio installation that is automatically configured by the
base station with little technician intervention. By installing one AirStar base
station, the service provider can attain coverage of many potential subscribers.
For example, a typical cell at 10 GHz or 26 GHz can cover ranges from 110 to 275
square miles or 5 to 15 square miles, respectively, depending on local
conditions, and has a transmission capacity equivalent to approximately 400 to
450 T1 lines, or an aggregate capacity of over 600 Mbps. Compared to other
broadband access technologies that often require lengthy and expensive plant
upgrades before offering service or do not support integrated voice and
symmetrical data services, AirStar allows a service provider to rapidly deploy
integrated voice and high-speed data services as demand warrants.

STRATEGY

      Our objective is to be the leading supplier of broadband wireless access
systems used by competitive service providers at multiple licensed frequencies
worldwide. Key elements of our strategy include the following:

      Increase Deployments within Our Existing Service Provider Base.  As the
needs of service providers evolve, we intend to extend product features to
leverage the success achieved at key service providers. We believe that we are
one of the first vendors to deliver a commercially available point-to-multipoint
broadband access system and thus have an early mover advantage. To date, service
providers have deployed the AirStar system in limited commercial rollouts or
trials. We intend to convert early design wins within our existing service
provider base into large-scale commercial deployments. We expect the average
time between trial and commercial rollout to decrease as these service providers
successfully deploy service to subscribers and become more familiar with the
system.

      Drive Deployments by New Service Providers.  We believe that our
visibility as one of the first vendors to commercially offer point-to-multipoint
broadband wireless access products will provide additional customer trials and
reference sales. We intend to utilize successful deployments at existing service
providers as reference accounts for new service providers. Our products are
designed to provide price and performance advantages that will help generate new
revenues rapidly for many service providers that license broadband wireless
spectrum worldwide. Consequently, we intend to aggressively expand our product
marketing and development beyond existing service providers at the 10 and 26 GHz
frequencies and into new markets domestically and internationally to serve a
broader service provider base. For example, we intend to conduct 38 GHz trial
installations in 1999, allowing us to serve CLECs at that frequency in the U.S.
market.

      Provide Competitive Advantages to Service Providers.  We intend to
continue to focus our product development efforts on features that enable
service providers to deploy differentiated, profitable services to their
business subscribers. The AirStar system allows service providers to rapidly and
cost-effectively deploy voice and data services when demand warrants. As service
providers begin to deploy AirStar on a broader basis, we expect they will demand
support for additional data and voice services and higher bandwidth interfaces
to increase their market share. We intend to offer new features that will enable
service providers to further differentiate their services. For example, we
expect to introduce support for ISDN-PRI and Frame Relay interfaces and up to 16
Mbps burst rates in 1999.

      Strengthen and Expand Relationships with Leading Communications Equipment
Vendors.  We intend to build on our success with Lucent and Siemens/Italtel to
meet the needs of service providers seeking to deploy large-scale networks and
to expand our service provider base. Our relationships with these two vendors
enable service providers deploying AirStar to access turnkey services, such as
system integration, and to receive an increased level of customer service. We
believe the provision of these turnkey services can facilitate broader
deployments worldwide. We further believe that leading communications equipment
vendors have a global sales presence and are in the strongest position to
provide service providers with system integration and comprehensive services and
support. Thus, we believe strengthening these relationships and selectively
establishing new relationships will facilitate increased volume deployments of
our products in the global market.

      Capitalize on Technology Leadership to Rapidly and Cost Effectively
Introduce New Products. Our platform enables dynamic bandwidth allocation by
integrating a number of technical competencies, including millimeter wave radio
design, data networking and network management software. We believe integrating
these competencies is highly complex, and we intend to leverage our technology
expertise to introduce new products and features rapidly and cost effectively.
Our modular architectural design enables us to reuse many common networking
elements and protocol software. As a result, the introduction of products in a
new frequency typically only requires relatively simple modifications in the
radio elements rather than the extensive development time and costs of entirely
redesigned equipment.

                                       33
<PAGE>   38

      Leverage Third-Party Customer Support to Scale Rapidly.  We are actively
training our system integrators, our other resellers and service providers
themselves in the operation and maintenance of the AirStar system. Many of our
service providers and system integrators have extensive experience in deploying
and provisioning broadband networks on a large scale. We plan to work closely
with our system integrators and service providers to enable them to provide
their own primary and secondary tiers of support for the AirStar system while
our engineers and customer service personnel will provide backup support on a
24-hour, 7-day basis. By educating our system integrators and service providers'
personnel about primary and secondary levels of support, we intend to scale our
business rapidly as service providers worldwide transition from trials to
commercial deployments.

PRODUCTS

      The AirStar system is typically deployed in a cellular, hub-and-spoke
architecture. Each cell has a central hub that can provide immediate coverage of
a particular area, with coverage depending on the licensed frequency, local
conditions and the service availability chosen by the service provider. The
AirStar system consists of integrated network and millimeter wave radio
components located at a central hub and at multiple subscriber locations within
a cell. Components of this system, which are described below, are the Base
Station, the Base Radio Unit, the Subscriber Radio Unit and Subscriber Access
System, all of which are managed by the AirView LE network management software.
Equipment at the hub consists of the Base Station and the Base Radio Unit.
Equipment at a subscriber's premises consists of a Subscriber Access System and
a Subscriber Radio Unit. The AirView LE is typically used at the service
provider's Metropolitan Switching Center, or MSC, where it is used to remotely
monitor the subscriber and the hub equipment. The table below shows the coverage
statistics for a typical installation and configuration under common local
conditions in the geographic regions where we expect many of our products to be
deployed.

      The Base Radio Units at the hub site send and receive simultaneous
broadband transmissions from multiple Subscriber Radio Units. The system
schedules transmissions from each subscriber on a packet-by-packet basis. The
Base Station prioritizes the transmissions and allocates just enough bandwidth
or time slots to complete the transfer of each packet. The Base Station and the
Subscriber Access System process and manage the information transmitted by the
radio components over the air. Security of the transmissions over the air is
achieved through discrete identifiers for each of the Subscriber Access Systems
and bit-level scrambling of the digital transmission through our air interface
protocol. This traffic is processed and delivered to the service provider's MSC,
where the voice and data traffic is interconnected with the public switched
telephone network for voice networks, the Internet backbone or public frame
relay networks.

   3. Right Central Section and Right Section. A diagram depicting the
"backbone" with a cloud depicting traffic from the Base Station being converted
into several networks depicted by clouds: Internet, Frame Relay, PSTN, TDM,
Mobile Switching Center and ATM.

      Base Station. Each hub can be configured to provide full redundancy, as
required by telecom service providers, for each of the Base Station components
and the Base Radio Units. A typical Base Station configuration requires a single
Base Station Shelf, which houses several Base Sector Controllers, and is
connected to several Base Modem Units. The design of the Base Station greatly
facilitates redundancy configuration compared to competing solutions that
require much more space.

        - BSS. The Base Station Shelf is a chassis with an ATM backplane that
          houses the Base Sector Controllers and is connected to the Base Modem
          Unit. The BSS aggregates traffic from multiple Base Sector Controllers
          and enables them to interface with the various public wide area
          networks. It provides network interfaces to these wide area networks
          at rates from 34 Mbps (E3) or 45 Mbps (DS3) to 155 Mbps (OC-3/STM-1).

        - BSC. The Base Sector Controller controls activity within each sector
          by shaping, policing and grooming traffic received from multiple
          subscribers. These functions combine to provide network management and
          routing within sectors. The BSC supports the CellMAC protocol in
          hardware and software and multiplexes and concentrates ATM traffic to
          the ATM network through the BSS' ATM UNI trunk. It has built-in Simple
          Network Management Protocol, or SNMP, remote management agents, and
          enables redundancy support and switching.

        - BMU. The Base Modem Unit works together with the Base Radio Unit that
          covers a particular sector. It supports high-speed quadrature
          amplitude mode, or QAM, modulation to convert air interface signals
          into digital bit stream by using burst modulation techniques.

      BRU. The Base Radio Unit is a radio transceiver with a single, built-in
sector antenna covering a 90(LOGO) sector. It is compact and lightweight, has a
low profile and is easy to install and align. The BRU transmits and receives
signals from the Subscriber Radio Unit. A typical Base Station configuration
would include four BRUs to cover the whole cell area. We are currently testing a
new release that supports 45(LOGO)

                                       35
<PAGE>   40

sectors that will enable higher transmission capacity in some configurations. We
expect this release to be available to our customers in 1999.

      SRU.  The Subscriber Radio Unit is a radio transceiver with a single
directional antenna with a plug-and-play feature resulting from automatic
frequency tuning. We offer the SRU with built-in or external antennas. It is
compact and lightweight, has a low profile and is easy to install and align. The
SRU transmits and receives signals from the BRU.

      SAS.  The Subscriber Access System provides the subscriber premises
interfaces and translates voice and data traffic to asynchronous transfer mode,
or ATM, cells for air transmission in a TDMA CellMAC format to and from the Base
Station. It supports the following features:

        - Software interfaces to full and fractional T1/E1 and Ethernet for IP
          over ATM. We are currently testing a new release that adds intelligent
          voice processing for ISDN-PRI and DASS2, a 100 BaseT interface and
          Frame Relay. We expect this release to be available to our customers
          in 1999.

        - Ability to request, through the CellMAC air interface protocol, and
          support high-speed sustained transmission up to rates in excess of 500
          Kbps to and from the Base Station and burst transmissions up to
          channel rates of 8 Mbps. We are currently testing a new release that
          supports high-speed sustained transmission up to rates in excess of 3
          Mbps and burst transmission up to channel rates of 16 Mbps. We expect
          this release to be available to our customers in 1999.

        - Remote monitoring of the SRUs.

      AirView LE.  All components of the AirStar network are managed remotely by
our AirView Link Explorer software, using SNMP. With AirView LE, an SRU, once
installed, can "self-admit" into the network, saving configuration and
installation time, and SAS software upgrades can be supported remotely. AirView
LE provides remote SNMP monitoring of all configuration items and alarms. We are
currently testing a new release that enables AirView to interface with leading
third-party network management systems, enabling service provisioning, fault
management, performance monitoring and simultaneous access by multiple network
operators. We expect this release to be available to our customers in 1999. This
remote and simultaneous access capability supports the management of regional or
national networks.

TECHNOLOGY

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

      CellMAC Air Interface Protocol.  We believe our proprietary ATM-based
CellMAC protocol maximizes the benefit of point-to-multipoint transmission
through our TDMA/ATM architecture, and advanced TDMA-based burst modulation and
demodulation techniques. CellMAC schedules transmissions from each subscriber on
a packet-by-packet basis. It allows subscribers to request additional bandwidth
from the Base Station for bursty data services through a bandwidth reservation
mechanism that requires little wasted spectrum. The Base Station can prioritize
the requests according to service level agreements and allocates just enough
bandwidth or time slots to complete the transfer of each packet. Traffic from
each subscriber terminal shares the bandwidth on a packet-by-packet basis, as
necessary, to fulfill the quality of service for each subscriber.

      ATM Architecture.  We have implemented ATM/TDMA technology over the air
interface to efficiently combine constant bit rate voice and variable bit rate,
bursty packet data onto a single bit stream. CellMAC is our implementation of
ATM protocol over the air. We believe ATM is the only standardized technology
that can transport voice and data traffic simultaneously and maintain QoS for
each traffic type: low end-to-end delay for voice, and statistical multiplexing
and fair sharing for bursty data. With statistical

                                       36

multiplexing of bursty data services, bandwidth for IP services can be provided
based on average throughput requirements rather than peak throughput
requirements. As a result, the capacity of the transmission channel is increased
by this peak to average throughput ratio, resulting in better use of spectrum
and thus lower equipment expenditures.

      Burst Modulation and Millimeter Wave Radio Technology.  During the same
time point-to-point wireless transmission evolved toward point-to-multipoint
topologies, modulation technology migrated from frequency shift keying, or FSK,
to the more bandwidth and power efficient QAM modulation. This has led to demand
for increased performance in radio design as well as improved operational
robustness. Higher throughput and lower power requirements necessitate advanced
radio design. Since our inception, we have worked extensively on radio designs
and volume manufacturing processes to create robust yet cost-effective radios
that support QAM modulation. The current AirStar radios are our third generation
design.

      System and Services Software.  Our software architecture and use of
object-oriented design principles for both real-time and network management
software are key to making our AirStar software modular and adjustable to
additional communications protocols. Our software extends the ability of the
AirStar system to enable the inter-working of voice protocols and support
statistical multiplexing of voice services. In a release we are currently
testing, our software extends the capabilities of the CellMAC protocol to
provide dynamic bandwidth allocation to voice services, such as ISDN PRI and
DASS2.

SALES AND MARKETING

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

      We also target key strategic accounts with our direct sales force. In
determining which accounts to service directly, we identify those that are key
early adopters that can help drive the product feature sets in a manner that
will better address the needs of the marketplace as a whole. Regardless of the
actual distribution channel that services the account, our direct sales force
maintains contact with the service provider and the system integrator account
team. This contact keeps us close to the evolving needs of the service providers
and helps ensure that we are well positioned within each account. In some
markets, we have established distribution relationships with local resellers
that also provide support and maintenance to the service providers they cover.

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

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

STRATEGIC RELATIONSHIPS

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

        - Lucent.  Under an OEM agreement we signed with Lucent in October 1998
          after extensive qualifying and testing of our AirStar product, Lucent
          will sell and market our AirStar equipment on a non-exclusive basis
          for a period of up to three years, with an option to extend this
          initial period. Lucent is currently marketing the AirStar product
          under the name Lucent OnDemand. We have agreed to manufacture and sell
          our products to Lucent and to provide Lucent with technical support
          and assistance in the development of customer proposals. Lucent plans
          to offer the OnDemand solution as part of an end-to-end solution with
          a complete suite of support services, NetCare(R) that includes
          planning, design and consulting, network implementation and
          integration and administration services and tools as well as
          comprehensive support. We have also entered into an accelerated
          development agreement with Lucent to collaborate on the development of
          the 38 GHz version of the AirStar.

        - Siemens - Italtel.  Italtel is an entity that is owned 50% by Siemens
          and 50% by Telecom Italia. Siemens has advised us that Italtel serves
          as the center of competence of radio technology in the Siemens group
          of affiliated companies. Under an OEM agreement we signed with Italtel
          in November 1997, Siemens and some of its affiliates will sell and
          market our products on a non-exclusive basis for a period of up to
          five years and we will manufacture and sell these products. Siemens is
          currently marketing the AirStar product under the name Siemens SRA MP.
          Siemens/Italtel plans to sell our products as part of an integrated
          network solution. Italtel has also made an equity investment in Netro.

CUSTOMERS

      We target service providers worldwide that have broadband wireless
spectrum rights or are planning to acquire rights to deliver broadband services
to subscribers. We began shipping the beta AirStar system to service providers
in the third quarter of 1998. Our direct sales in most cases are to our system
integrators, Lucent and Siemens/Italtel, or to distributors that in turn sell to
service providers. The following is a partial list of service providers or
enterprises that have purchased or deployed our AirStar system, either as a
trial system or to carry traffic to subscribers, and the locations of
deployment, and in connection with which we have recognized revenues in excess
of $80,000.

      In addition, we have service provider trials in Germany and Japan and
several trial installations with system integrators in the U.S. and Europe.

OPERATIONS AND MANUFACTURING

        Our manufacturing activities, based in our San Jose facility, consist
primarily of low-volume production and procurement. Our strategy is to outsource
manufacturing to contract manufacturers, which

                                       38
<PAGE>   43

have the expertise and ability to achieve cost reductions associated with volume
manufacturing and to respond quickly to customer orders while maintaining high
quality standards. This also serves to turn some of our fixed costs into
variable costs and enables us to enjoy the purchasing efficiencies of these
larger manufacturers. We have manufacturing contracts in place with Solectron
Corporation and Microelectronic Technologies, Inc. of Taiwan (MTI). MTI will
manufacture millimeter wave radio equipment, and Solectron will manufacture both
millimeter wave radio equipment and digital system components. Our agreement
with MTI makes us MTI's exclusive customer for terrestrial point-to-multipoint
millimeter wave radio equipment, provided we meet annual purchase minimums.

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

RESEARCH AND DEVELOPMENT

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

      We believe that our future success depends on our continued investment in
research and development in core radio, networking and software technologies,
and we expect to continue to invest a significant portion of revenues in this
area. Our net research and development expenditures for 1996, 1997, 1998 and the
three months ended March 31, 1999 were $10.4 million, $15.3 million, $16.1
million and $4.2 million. We are committed to an ongoing new product development
program that is based on an assessment of service providers' needs and
technological changes in the communications market. We are currently investing
significant resources in enhancing our network management software, integrating
base station components, extending the capabilities, frequencies and capacity of
AirStar's transmission, improving performance and accelerating cost reduction.

CUSTOMER SERVICE

      A high level of continuing service and support is critical to our
objective of developing long-term customer relationships. Our customer support
organization is based in our San Jose headquarters. We also have a customer
service presence in the United Kingdom and Germany. Our headquarters support
organization serves as the interface to our research and development group to
escalate certain problems and also provides information about customers' needs
to the marketing and research and development organizations. Our customer
support model consists of three tiers of support: local problem isolation, fault
isolation and repair, and expert level support.

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

      We have a number of flexible hardware and software maintenance and support
programs available for products beyond the applicable warranty period, depending
on our customer preferences. In the case of trials, we offer an evaluation
support package, where training, installation and acceptance testing are
delivered within specific time frames. These activities are usually performed
on-site by our personnel. As more trials begin carrying commercial traffic, we
will migrate the support capabilities to off-hours, 24-hour, 7-day support, and
continue to provide expert level support for service providers and system
integrators.

COMPETITION

      The market for broadband access products generally, and
point-to-multipoint wireless access products specifically, is rapidly evolving
and highly competitive. As a provider of broadband point-to-multipoint wireless
access products, we compete with several large telecommunications equipment
suppliers such as Alcatel, Bosch, Ericsson, Hughes, Newbridge, Nortel and
Spectrapoint, a newly formed joint venture between Cisco and Motorola, as well
as with smaller start-up companies. In addition, well capitalized companies such
as Nokia are potential entrants into the market. As an industry, broadband
point-to-multipoint wireless access products compete with other potential
broadband access solutions, such as wireless point-to-point technologies and
broadband satellite, wireline technologies that utilize existing infrastructure,
such as digital subscriber line, or DSL, fiber optic cable, cable modem
technologies and leased lines.

      We expect competition to persist and intensify in the future. Many of our
competitors are substantially larger than we are and have significantly greater
financial, sales and marketing, technical, manufacturing and other resources and
more established distribution channels. These competitors may be able to respond
more rapidly to new or emerging technologies and changes in customer
requirements or devote greater resources to the development, promotion, sale and
financing of their products than we can. Furthermore, some of our competitors
may make strategic acquisitions or establish cooperative relationships among
themselves or with third parties to increase their ability to rapidly gain
market share by addressing the needs of our prospective customers. These
competitors may enter our existing or future markets with solutions that may be
less expensive, provide higher performance or additional features or be
introduced earlier than our solutions. We also expect that other companies may
enter our market with better products and technologies. If any technology that
is competing with ours is more reliable, faster, less expensive or has other
advantages over our technology, then the demand for our products and services
would decrease, which would seriously harm our business.

      We expect our competitors to continue to improve the performance of their
current products and introduce new products or new technologies as industry
standards and customer requirements evolve that may supplant or provide lower
cost alternatives to our products. Successful new product introductions or
enhancements by our competitors could reduce sales or the market acceptance of
our products, perpetuate intense price competition or make our products
obsolete. To be competitive, we must continue to invest significant resources in
research and development, sales and marketing and customer support. We cannot be
sure that we will have sufficient resources to make these investments or that we
will be able to make the technological advances necessary to be competitive. As
a result, we may not be able to compete effectively against our competitors. Our
failure to maintain and enhance our competitive position within the market may
adversely affect our business. Some of the factors on which we compete are:

<TABLE>
<S>    <C>
    -  availability of product
    -  availability of financing
    -  reliability of product
    -  low entry price point
    -  ability to scale
    -  ease of use
    -  bandwidth of product
    -  operating experience
    -  price-performance
    -  breadth of frequency offerings
    -  completeness of integration
    -  customer support
    -  multi-service capability
    -  manufacturing capacity
    -  network management software
    -  installed base
</TABLE>

      Increased competition is likely to result in price reductions, shorter
product life cycles, reduced gross margins, longer sales cycles and loss of
market share, any of which would adversely affect our business.

INTELLECTUAL PROPERTY

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

PROPERTIES

      We sublease an approximately 66,000 square foot facility in San Jose,
California, approximately 47,000 of which we currently use for executive offices
and for administrative, engineering, product development, manufacturing and
sales and marketing purposes. The remaining space is available for our use for
general offices, light manufacturing, storage or other related uses. The
sublease for this facility expires in September 2001.

EMPLOYEES

      As of March 31, 1999, we employed approximately 146 full-time employees
and 22 contract personnel. Our full-time employees include 50 people in
operations and manufacturing, 61 in engineering, 22 in sales, marketing and
customer service, and 13 in finance and administration. None of our employees is
represented by collective bargaining agreements, and we consider relations with
our employees to be good.

LEGAL PROCEEDINGS

      In March 1999, one of our former contract manufacturers, Quadrus
Manufacturing, a division of Bell Microproducts Inc., filed for binding
arbitration in Santa Clara County, California with respect to a dispute with us.
The arbitration involves claims by Quadrus for approximately $950,000 for
amounts allegedly owed by us for inventory purchased by Quadrus in anticipation
of our projected demand. In June 1999, we filed an answer and counterclaim
alleging damages of approximately $275,000 for product failures. We believe we
have meritorious defenses to their claim, and we intend to defend this
arbitration vigorously. However, we may not prevail in this arbitration. The
arbitration process is inherently uncertain. Our defense of this arbitration,
regardless of its eventual outcome, has been, and will likely continue to be,
time-consuming, costly and a diversion for our personnel. A failure to prevail
could result in us having to pay monetary damages to Quadrus, which could
materially harm our business.

of our Articles of Incorporation, effective upon the closing of this offering,
the terms of office of the directors will be divided into two classes: Class I,
whose term will expire at the annual meeting of shareholders to be held in 2000
or a special meeting held instead of that annual meeting, and Class II, whose
term will expire at the annual meeting of shareholders to be held in 2001 or a
special meeting held instead of that annual meeting. The Class I directors are
Messrs. Baruch, Douglas and Federman; the Class II directors are Messrs.
Ben-Efraim, Moley and Walecka. At each annual meeting of shareholders after the
initial classification or special meeting held instead of an annual meeting, the
successors to directors whose terms will then expire will be elected to serve
from the time of election and qualification until the second annual meeting
following election or special meeting held instead of an annual meeting. In
addition, our Articles of Incorporation provide that the authorized number of
directors may be changed only by resolution of the board of directors. Any
additional directorships resulting from an increase in the number of directors
will be distributed among the two classes so that, as nearly as possible, each
class will consist of one-half of the directors. This classification of the
board of directors may have the effect of delaying or preventing changes in
control or management of Netro. Although directors of Netro may be removed for
cause by the affirmative vote of the holders of a majority of the common stock,
our Articles of Incorporation provide that holders of two-thirds of the common
stock must vote to approve the removal of a director without cause.

BOARD COMPENSATION

      We do not currently compensate our directors, but directors are reimbursed
for out-of-pocket expenses incurred in connection with attendance at meetings of
the board of directors or any committees of the board of directors. Our
directors are eligible to participate in our 1996 Stock Option Plan and, to the
extent that a director is an employee of Netro, to participate in our 1999
Employee Stock Purchase Plan. Our directors who are not employees also receive
periodic stock option grants under our 1997 Directors' Stock Option Plan.

BOARD COMMITTEES

      Upon the effectiveness of this offering, the Compensation Committee will
consist of Messrs. Baruch and Walecka. The Compensation Committee reviews and
approves the compensation and benefits for our executive officers and grants
stock options under our stock option plans; and makes recommendations to the
board of directors regarding such matters. Upon the effectiveness of this
offering, the Audit Committee will consist of Messrs. Douglas and Federman. The
Audit Committee makes recommendations to the board of directors regarding the
selection of independent auditors; reviews the results and scope of the

                                       44

audit and other services provided by our independent auditors; and reviews and
evaluates our audit and control functions.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      No member of the Compensation Committee serves as a member of the board of
directors or compensation committee of any entity that has one or more executive
officers serving as a member of our board of directors or Compensation
Committee. See "Certain Transactions" for a description of transactions between
Netro and entities affiliated with members of the Compensation Committee.

      The following table provides certain summary information regarding stock
options granted to the Named Executive Officers during the fiscal year ended
December 31, 1998.

      Individual grants below consist of options granted pursuant to Netro's
1995 and 1996 Stock Option Plans. The 5% and 10% assumed annual rates of
compounded stock price appreciation are mandated by the rules of the SEC. There
can be no assurance that the actual stock price appreciation over the ten-year
option term will be at the assumed 5% and 10% levels or at any other defined
level. Unless the market price of the common stock appreciates over the option
term, no value will be realized from the option grants made to the Named
Executive Officers.

EMPLOYMENT AND CHANGE OF CONTROL AGREEMENTS

      In March 1995, Netro entered into an employment agreement with Gideon
Ben-Efraim, Netro's Chief Executive Officer, President and Director. The initial
base salary under this agreement was $120,000 per year, with an automatic
increase to $145,000 upon the closing of Netro's Series A preferred stock
financing. Mr. Ben-Efraim's salary has been increased pursuant to annual review
by the Board of Directors. Pursuant to the agreement, Mr. Ben-Efraim receives a
cash bonus equal to 20% of his base salary, in addition to participation in any
annual executive bonus plan of Netro. In the event of termination other than for
cause, the agreement entitles Mr. Ben-Efraim to severance benefits equal to
twelve months of his then-current base salary as well as a lapse of 25% of
Netro's repurchase option on unvested shares then held by Mr. Ben-Efraim,
including those held by his family trust. If Netro enters into certain change-
of-control transactions, the vesting of Mr. Ben-Efraim's options and shares
subject to repurchase, including those held by his family trust, will accelerate
so that all unvested options and shares would become fully vested upon the
closing of the change-of-control transaction. The agreement also provides that,
in the event Netro grants registration rights to any officers or investors,
Netro will grant no less favorable rights to Mr. Ben-Efraim.

      Netro has entered into change-of-control agreements with Richard M. Moley,
Gideon Ben-Efraim, Michael T. Everett, Matthew Powell, John Perry, Man Wong and
James Hannigan. Pursuant to Mr. Moley's agreement, in the event of a merger,
consolidation, acquisition or other change-of-control event, unvested shares and
options held by Mr. Moley, or his affiliates, will vest immediately with respect
to the number of shares that would otherwise have vested through the date that
is two years after the next monthly vesting date following the change-of-control
event. Mr. Ben-Efraim and Mr. Everett each have an agreement with Netro which
provides that, if his employment with Netro is involuntarily terminated without
cause within one year following a change of control or if he is not offered a
comparable position by the acquiror, each of his unvested options will vest
immediately with respect to the number of shares that would otherwise have
vested pursuant to the terms of such option through the date that is two years
after the next monthly vesting date following the change-of-control event.
Pursuant to the agreement for Mr. Powell, in the event that Mr. Powell is
involuntarily terminated without cause following a change of control and is not
offered a comparable position by the acquiror, unvested shares and options held
by Mr. Powell will vest immediately with respect to the number of shares that
would otherwise have vested through the first fifteen months of employment, if
the termination occurs before Mr. Powell has completed one year of employment.
However, if the termination occurs after two full years of employment, the
accelerated vesting will occur with respect to an additional twelve months of
vesting. Pursuant to each of the agreements for Mr. Perry, Mr. Wong and Mr.
Hannigan, in the event the employee is involuntarily terminated without cause
following a change of control and without an offer of a comparable position with
the acquiror, and the termination occurs before the employee has completed one
year of employment, unvested shares and options held by that employee will vest
immediately with respect to the number of shares that would otherwise have
vested through the first year of employment.

STOCK PLANS

1996 Stock Option Plan

      Our 1996 Stock Option Plan is intended to serve as the successor equity
incentive program to our 1995 Stock Option Plan. No option grants will be made
under the 1995 Stock Option Plan after this offering. The 1996 Stock Option Plan
provides for the grant of incentive stock options, as defined in Section 422 of
the Internal Revenue Code, to employees and the grant of nonstatutory stock
options to employees, non-employee directors and consultants. The purposes of
the 1996 Stock Option Plan are to attract and retain the best available
personnel, to provide additional incentives to our employees and consultants and
to promote the success of our business. Options outstanding under the 1995 Stock
Option Plan are subject to substantially the same terms as described below for
option awards under the 1996 Stock Option Plan.

                                       47
<PAGE>   52

      The 1996 Stock Option Plan was adopted by our board of directors in
December 1996 and approved by our shareholders in January 1997. Unless
terminated earlier by the board of directors, the 1996 Stock Option Plan will
terminate in December 2006. The 1996 Stock Option Plan was amended by our board
of directors in April 1999 and June 1999 to increase the total number of shares
reserved for issuance by 2,120,284 shares, to provide for an automatic annual
increase in the number of shares reserved for issuance and to incorporate other
changes. The 1996 Stock Option Plan amendments will be submitted to our
shareholders for their approval prior to the date of this offering. As of June
11, 1999, a total of 8,800,000 shares of common stock had been reserved for
issuance under the 1996 Stock Option Plan, which includes the aggregate number
of shares remaining available for grant under the 1995 Stock Option Plan as of
the date of this offering. The number of shares reserved for issuance under the
1996 Stock Option Plan will be subject to an automatic annual increase on the
first day of each of our fiscal years beginning in 2001 and ending in 2005 equal
to the least of (1) 750,000 shares; (2) 3% of our outstanding common stock on
the last day of the immediately preceding fiscal year; or (3) a lesser number of
shares determined by the administrator. As of June 11, 1999, options to purchase
an aggregate of 4,562,478 shares of common stock were outstanding under the 1995
Stock Option Plan and 1996 Stock Option Plan at a weighted average exercise
price of $1.99, 2,418,542 shares had been issued upon exercise of outstanding
options, and 2,290,523 shares remained available for future grant.

      The Compensation Committee currently administers the 1996 Stock Option
Plan and the Board of Directors has designated the Compensation Committee to
administer the 1996 Stock Option Plan with respect to different groups of
service providers. The administrator of the 1996 Stock Option Plan will
determine numbers of vesting schedules for and exercise prices for options,
granted under the 1996 Stock Option Plan, provided, however, an individual
employee may not receive option grants for more than 1,000,000 shares in any
fiscal year.

      The exercise price of incentive stock options must be at least equal to
100% of the fair market value of our common stock on the date of grant, and no
less than 110% of the fair market value in the case of incentive stock options
granted to an employee who holds, at the time the option is granted, more than
10% of the total voting power of all classes of our stock or any parent's or
subsidiary's stock. Nonstatutory stock options granted under the 1996 Stock
Option Plan will have an exercise price as determined by the administrator of
the 1996 Stock Option Plan, provided that the exercise price of a nonstatutory
stock option intended to qualify as performance-based compensation under Section
162(m) of the Internal Revenue Code must equal at least 100% of the fair market
value of the common stock on the date of grant. Payment of the exercise price
may be made in cash or other form of consideration approved by the
administrator. The administrator determines the term of options, which may not
exceed ten years, or five years in the case of an incentive stock option granted
to an employee who holds, at the time the option is granted, more than 10% of
the total voting power of all classes of our stock or any parent's or
subsidiary's stock. No option may be transferred by the optionee other than by
will or the laws of descent or distribution, provided, however, that the
administrator may in its discretion provide for the transferability of
nonstatutory stock options granted under the 1996 Stock Option Plan. Each option
may be exercised during the lifetime of the optionee only by the optionee or a
permitted transferee. The administrator determines when options become
exercisable. Options granted under the 1996 Stock Option Plan generally become
exercisable at the rate of 1/4th of the total number of shares subject to the
options twelve months after the date of grant, and 1/48th of the total number of
shares subject to the options each month thereafter. To the extent an optionee
would have the right in any calendar year to exercise for the first time one or
more incentive stock options for shares having an aggregate fair market value in
excess of $100,000 as of the date the options were granted, the excess options
will be treated as nonstatutory stock options.

      In the event of a sale of all or substantially all of the assets of Netro,
or the merger or consolidation of Netro with or into another corporation in
which the successor corporation issues its securities to our shareholders,
outstanding options will be assumed or substituted by the successor corporation.
If the successor corporation does not agree to this assumption or substitution,
the options will terminate upon the closing of the transaction.

                                       48
<PAGE>   53

      The board of directors may amend, modify or terminate the 1996 Stock
Option Plan at any time as long as any amendment, modification or termination
does not impair vesting rights of plan participants and provided that
shareholder approval is required for an amendment to the extent required by
applicable law, regulations or rules. The 1996 Stock Option Plan will terminate
in December 2006 unless the board of directors terminates it earlier.

1999 Executive Stock Plan

      Our 1999 Executive Stock Plan was adopted by the board of directors in
April 1999 and approved by the shareholders in May 1999. A total of 1,195,000
shares of common stock has been reserved for issuance under the 1999 Executive
Stock Option Plan. As of June 11, 1999, options to purchase 1,195,000 shares of
common stock with a weighted average exercise price of $3.50 had been issued, of
which 1,195,000 shares were outstanding, and no shares remained available for
future option grants. Unless terminated earlier, the 1999 Executive Stock Option
Plan will terminate in April 2009. No further options will be granted under the
1999 Executive Stock Plan.

      The terms of options issued under the 1999 Executive Stock Option are
generally the same as those that may be issued under the 1996 Stock Option Plan,
except with respect to the following features. The 1999 Executive Stock Option
Plan does not impose an annual limitation on the number of shares subject to
options that may be issued to any individual employee.

      Options granted under the 1999 Executive Stock Plan generally may be
exercised immediately after the grant date, but to the extent the shares subject
to the options are not vested as of the date of exercise, Netro retains a right
to repurchase any shares that remain unvested at the time of the optionee's
termination of employment by paying an amount equal to the exercise price times
the number of unvested shares. Options granted under the 1999 Executive Stock
Plan generally vest at the rate of 25% of the total number of shares subject to
the options twelve months after the date of grant and 1/48th of the total number
of shares subject to the options each month thereafter.

1997 Directors' Stock Option Plan

      The 1997 Directors' Stock Option Plan was adopted by the board of
directors in December 1997 and amended in June 1999. A total of 300,000 shares
of common stock has been reserved for issuance under the Directors' Stock Option
Plan. As of June 11, 1999, options to purchase 125,000 shares of common stock
were outstanding under the 1997 Directors' Stock Option Plan at a weighted
average price of $2.00. No shares had been issued upon exercise of outstanding
options and 175,000 shares remained available for future grants.

      Under the 1997 Directors' Stock Option Plan, as amended, each non-employee
director who first becomes a non-employee director after the effective date of
the amendment receives an automatic initial grant of an option to purchase
10,000 shares of common stock upon appointment or election. Initial grants to
non-employee directors are vested and exercisable in full as of the date of
grant. The 1997 Directors' Stock Option Plan also provides for annual grants of
options to purchase 10,000 shares of common stock on the first day of each of
our fiscal years to each non-employee director who has served on our board of
directors for at least six months, provided that a non-employee director who
received a 20,000 share initial grant under the original version of the 1997
Directors' Stock Option Plan shall be eligible to receive an annual grant of an
option to purchase 5,000 shares of common stock until the first day of our
fiscal year following the date on which the initial option has fully vested
under the terms of that option after which date each director shall be eligible
to receive an annual grant of an option to purchase 10,000 shares of common
stock. The annual grants to non-employee directors are vested and exercisable in
full as of the date of grant. In June 1999, our board of directors approved an
amendment to the terms of the annual grants issued in January 1999 to our
current non-employee directors, which amendment made those grants vested and
exercisable in full. The exercise price of all stock options granted under the
1997 Directors' Stock Option Plan shall be equal to the fair market value of a
share of Netro's common stock on the date of grant of the option. Options
granted under the 1997 Directors' Stock Option Plan have a term of ten

                                       49

years. However, unvested options will terminate when the optionee ceases to
serve as a director and vested options will terminate if they are not exercised
within 12 months after the director's death or disability or within 90 days
after the director ceases to serve as a director for any other reason.

      In the event of a dissolution or liquidation of Netro, sale of all or
substantially all of the assets of Netro or the merger or consolidation of Netro
in which Netro is not the surviving corporation or any other capital
reorganization in which the ownership of more than 50% of the total combined
voting power of our outstanding securities changes hands, each nonemployee
director will have either (1) a reasonable time within which to exercise the
option, including any part of the option that would not otherwise be
exercisable, prior to the effectiveness of such dissolution, liquidation, sale,
merger or reorganization, at the end of which time the option will terminate, or
(2) the right to exercise the option, including any part that would not
otherwise be exercisable, or receive a substitute option with comparable terms,
as to an equivalent number of shares of stock of the corporation succeeding
Netro or acquiring its business by reason of the dissolution, liquidation, sale,
merger or reorganization.

      The 1997 Directors' Stock Option Plan is designed to work automatically
without administration. However, to the extent administration is necessary, it
will be performed by the Board of Directors other than the director or directors
that have a personal interest at stake. Although the Board of Directors may
amend or terminate the 1997 Directors' Stock Option Plan, it may not take any
action that may adversely affect any outstanding option. The 1997 Directors'
Stock Option Plan will have a term of ten years unless terminated earlier.

1999 Employee Stock Purchase Plan

      Our 1999 Employee Stock Purchase Plan was adopted by the board of
directors in June 1999 and will be submitted for approval by the shareholders in
July 1999. The 1999 Employee Stock Purchase Plan becomes effective on the date
of this prospectus. A total of 1,000,000 shares of common stock has been
reserved for issuance under the 1999 Employee Stock Purchase Plan. The number of
shares reserved for issuance under the 1999 Employee Stock Purchase Plan will be
subject to an automatic annual increase on the first day of each of our fiscal
years beginning after 2001 and ending in 2005 equal to the least of: (1) 250,000
shares; (2) 1% of our outstanding common stock on the last day of the
immediately preceding fiscal year; or (3) a lesser number of shares determined
by the administrator. The 1999 Employee Purchase Plan will terminate in June
2019 unless terminated earlier in accordance with its provisions.

      The 1999 Employee Stock Purchase Plan, which is intended to qualify under
Section 423 of the Code, provides our employees with an opportunity to purchase
our common stock through accumulated payroll deductions. The 1999 Employee Stock
Purchase Plan will be administered by the board of directors or by a committee
appointed by the board of directors. The 1999 Employee Stock Purchase Plan
permits an eligible employee to purchase common stock through payroll deductions
of up to 15% of an employee's compensation. Employees, including officers and
employee directors, of Netro, or of any majority-owned subsidiary designated by
the board of directors, are eligible to participate in the 1999 Employee Stock
Purchase Plan if they are employed by Netro or any such subsidiary for at least
20 hours per week and more than five months per year. Unless the board of
directors or its committee determines otherwise, the 1999 Employee Stock
Purchase Plan will be implemented by a series of overlapping offering periods
generally of 24 months' duration with new offering periods, other than the first
offering period, commencing on February 1 and August 1 of each year. Each
offering period will be divided into four consecutive purchase periods of
approximately six months' duration. The first offering period is expected to
commence on the date of this offering and end on July 31, 2001; the initial
purchase period is expected to end on January 31, 2000. The price at which
common stock will be purchased under the 1999 Employee Stock Purchase Plan is
equal to 85% of the fair market value of the common stock on the first day of
the applicable offering period or the last day of the applicable purchase
period, whichever is lower. Employees may end their participation in an offering
period at any time, and participation automatically ends on termination of
employment.

                                       50
<PAGE>   55

      Under the 1999 Employee Stock Purchase Plan, no employee may be granted an
option if immediately after the grant the employee would own stock and/or hold
outstanding options to purchase stock equaling 5% or more of the total voting
power or value of all classes of our stock or that of our subsidiaries. In
addition, no employee may be granted an option under the 1999 Employee Stock
Purchase Plan if the option would permit the employee to purchase stock under
all of our employee stock purchase plans in an amount that exceeds $25,000 of
fair market value for each calendar year in which the option is outstanding at
any time, In addition, no employee may purchase more than 2,000 shares of common
stock under the 1999 Employee Stock Purchase Plan in any one purchase period. If
the fair market value of the common stock on a purchase date other than the
final purchase date of an offering period is less than the fair market value at
the beginning of the offering period, each participant in the 1999 Employee
Stock Purchase Plan will automatically be withdrawn from the offering period as
of the purchase date and re-enrolled in a new 24-month offering period on the
first business day following the purchase date.

      The 1999 Employee Purchase Plan provides that in the event of a merger of
Netro with or into another corporation or a sale of all or substantially all of
its assets, each right to purchase stock under the Purchase Plan will be assumed
or an equivalent right substituted by the successor corporation. However, our
board of directors will shorten any ongoing offering period so that employees'
rights to purchase stock under the 1999 Employee Stock Purchase Plan are
exercised prior to the transaction in the event that the successor corporation
refuses to assume each purchase right or to substitute an equivalent right. The
board of directors has the power to amend or terminate the 1999 Employee Stock
Purchase Plan as long as its action does not adversely affect any outstanding
rights to purchase stock thereunder. However, our board of directors may amend
or terminate the 1999 Employee Stock Purchase Plan or an offering period even if
it would adversely affect options in order to avoid our incurring adverse
accounting charges.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

      We have adopted provisions in our Articles of Incorporation that limit the
liability of our directors for monetary damages arising from a breach of their
fiduciary duty as directors to the fullest extent permitted by the California
Corporations Code. This limitation of liability does not affect the availability
of equitable remedies such as injunctive relief or rescission.

      Our Bylaws provide that we will indemnify our directors and officers to
the fullest extent permitted by California law, including circumstances in which
indemnification is otherwise discretionary under California law. We have entered
into indemnification agreements with our directors and officers containing
provisions that are in some respects broader than the specific indemnification
provisions contained in the California Corporations Code. The indemnification
agreements may require us to indemnify our directors and officers against
liabilities that may arise by reason of their status or service as directors or
officers, other than liabilities arising from willful misconduct of a culpable
nature, to advance their expenses incurred as a result of any proceeding against
them as to which they could be indemnified and to obtain directors' and
officers' insurance if available on reasonable terms. We currently have a policy
for directors' and officers' insurance, which we intend to replace with a
similar policy that provides coverage for matters relating to public offerings
of our securities.

      At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of ours in which indemnification would be
required or permitted. We are not aware of any threatened litigation or
proceeding that might result in a claim for such indemnification. We believe
that our charter provisions and indemnification agreements are necessary to
attract and retain qualified persons as directors and officers.

                             PRINCIPAL SHAREHOLDERS

      The following table sets forth information regarding the beneficial
ownership of Netro's common stock as of June 11, 1999 and as adjusted to reflect
the sale of the common stock offered by Netro pursuant to this prospectus and
conversion of all outstanding shares of preferred stock into shares of common
stock by (1) each of our directors, (2) each of our Named Executive Officers,
(3) all directors and executive officers as a group, and (4) each person who is
known by us to own beneficially more than 5% of our common stock.

      Except as otherwise noted, the address of each person listed in the table
is c/o Netro Corporation, 3860 North First Street, San Jose, CA 95134, and the
persons named in the table have sole voting and investment power with respect to
all shares of common stock shown as beneficially owned by them, subject to
community property laws where applicable.

      Applicable percentage of beneficial ownership is based on 38,276,583
shares of common stock outstanding as of June 11, 1999, together with applicable
options and warrants that are exercisable within 60 days of June 11, 1999 for
such shareholder. Beneficial ownership is determined in accordance with the
rules of the Securities and Exchange Commission. The number of shares
beneficially owned by a person includes shares of common stock subject to
options held by that person that are currently exercisable or exercisable within
60 days of June 11, 1999. Shares issuable pursuant to such options are deemed
outstanding for computing the percentage ownership of the person holding such
options but are not deemed outstanding for the purposes of computing the
percentage ownership of each other person. Percentages for beneficial ownership
after offering assume underwriters do not exercise their over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

      Following the closing of the sale of the shares offered hereby, our
authorized capital stock will consist of 100,000,000 shares of common stock and
5,000,000 shares of undesignated preferred stock.

COMMON STOCK

      As of March 31, 1999, there were 37,868,678 shares of common stock
outstanding that were held of record by approximately 176 shareholders after
giving effect to the conversion of our Series A preferred stock, Series B
preferred stock, Series C preferred stock, and Series D preferred stock into
common stock at a one-to-one ratio and the exercise of 57,028 warrants to
purchase shares of preferred stock and assuming no exercise of any other
outstanding options or warrants after March 31, 1999. Under the same
assumptions, there will be                shares of common stock outstanding
after giving effect to the sale of the shares of common stock offered by us.

      The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the shareholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available therefor. In
the event of a liquidation, dissolution or winding up of Netro, the holders of
common stock are entitled to share ratably in all assets remaining after payment
of liabilities, subject to prior rights of preferred stock, if any, then
outstanding. The common stock has no preemptive or conversion rights or other
subscription rights. There are no redemption or sinking fund provisions
available to the common stock. All outstanding shares of common stock are fully
paid and non-assessable.

PREFERRED STOCK

      Effective upon the closing of this offering, Netro will be authorized to
issue 5,000,000 shares of undesignated preferred stock. The board of directors
will have the authority to issue the undesignated preferred stock in one or more
series and to determine the powers, preferences and rights and the
qualifications, limitations or restrictions granted to or imposed upon any
wholly unissued series of undesignated preferred stock and to fix the number of
shares constituting any series and the designation of that series, without any
further vote or action by the shareholders. The rights of the holders of the
common stock will be subject to, and may be adversely affected by, the rights of
the holders of any preferred stock that may be issued in the future. The
issuance of preferred stock may have the effect of delaying, deferring or
preventing a change in control of Netro without further action by the
shareholders and may adversely affect the voting and other rights of the holders
of common stock. At present, we have no plans to issue any shares of preferred
stock. Furthermore, the preferred stock may have other rights, including
economic rights senior to the common stock, and, as a result, the issuance of
preferred stock could have a material adverse effect on the market value of the
common stock. We have no present plan to issue shares of preferred stock.

REGISTRATION RIGHTS OF CERTAIN HOLDERS

      The holders of 30,990,671 shares of common stock referred to in this
prospectus as Registrable Securities, or their transferees are entitled to
certain rights with respect to the registration of these shares under the
Securities Act. These rights are provided under the terms of an agreement
between Netro and the holders of Registrable Securities dated June 21, 1999.
Subject to certain limitations in this agreement, the holders of the Registrable
Securities may require, on two occasions at any time after six months from the
effective date of this offering, that Netro use its best efforts to register the
Registrable Securities for public resale. If we register any of our common stock
either for our own account or for the account of other security holders, the
holders of Registrable Securities are entitled to include their shares of common
stock in the registration. A holder's right to include shares in an underwritten
registration is subject to the ability of the underwriters to limit the number
of shares included in this offering. All fees, costs and expenses of such
registrations must be borne by Netro, and all selling expenses, including
underwriting

                                       56
<PAGE>   61

discounts, selling commissions and stock transfer taxes, relating to Registrable
Securities must be borne by the holders of the securities being registered.

      Additionally, holders of Registrable Securities may require on no more
than one occasion in a twelve-month period, that we register their shares for
public resale on Form S-3 or similar short-form registration, provided Netro is
eligible to use Form S-3 or similar short-form registration and provided further
that the value of the securities to be registered is at least $500,000. All
fees, costs and expenses of such registrations on Form S-3 and all selling
expenses, including underwriting discounts, selling commissions and stock
transfer taxes, relating to Registrable Securities must be borne by the holders
of the securities being registered.

ANTI-TAKEOVER PROVISIONS

      Upon completion of this offering, certain provisions of our charter
documents, including a provision eliminating the ability of shareholders to take
actions by written consent, may have the effect of delaying or preventing
changes in control or management of Netro, which could have an adverse effect on
the market price of our common stock. Our stock option and purchase plans
generally provide for assumption of our benefit plans or substitution of an
equivalent option of a successor corporation or, alternatively, at the
discretion of the board of directors, exercise of some or all of the options,
including those for non-vested shares, or acceleration of vesting of shares
issued pursuant to stock grants, upon a change of control or similar event. The
board of directors will have authority to issue up to 5,000,000 shares of
preferred stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of these shares without any further vote or action by
the shareholders. See " -- Preferred Stock."

WARRANTS

      As of March 31, 1999, warrants were outstanding to purchase an aggregate
of 57,028 shares of preferred stock at a weighted average exercise price of
$7.39 per share. Warrants to purchase 23,750 shares at $7.00 per share will
expire either two years from the date of an initial public offering or five
years from the date the warrants were granted, whichever is later. Warrants to
purchase 5,000 shares at $7.00 per share will expire either two years from the
date of an initial public offering or five years from the date the warrants were
granted, whichever is later. Warrants to purchase 8,997 shares at $7.78 per
share will expire either two years from the date of an initial public offering
or five years from the date the warrants were granted, whichever is later.
Warrants to purchase 19,281 shares at $7.78 per share will expire either three
years from the closing of an initial public offering or seven years from the
date the warrants were granted, whichever is later. The warrants to purchase
shares of preferred stock outstanding following this offering will convert into
warrants to purchase shares of common stock on the closing of this offering on a
one-to-one basis. Generally, each warrant contains provisions for the adjustment
of the exercise price and the aggregate number of shares issuable upon the
exercise of the warrant under certain circumstances, including stock dividends,
stock splits, reorganizations, reclassifications, consolidations and certain
dilutive issuances of securities at prices below the then existing warrant
exercise price. In addition, pursuant to a manufacturing and engineering
services agreement with MTI, Netro will issue stock to MTI as consideration for
engineering services upon the achievement by MTI of certain milestones, provided
that following Netro's initial public offering of common stock, Netro may elect
to pay such consideration in cash.

TRANSFER AGENT AND REGISTRAR

      The Transfer Agent and Registrar for our common stock is American Stock
Transfer & Stock Company.

LISTING

      We have applied to list our common stock on the Nasdaq National Market

                        SHARES ELIGIBLE FOR FUTURE SALE

      Upon the closing of this offering, we will have           shares of common
stock outstanding, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options to purchase common stock after
June 11, 1999. All of our directors and executive officers and some of our
shareholders, holding in the aggregate           shares of our common stock,
have agreed that they will not, without the prior written consent of Merrill
Lynch on behalf of the underwriters, offer, sell or otherwise dispose of any
shares of common stock or options to acquire shares of common stock during the
180-day period following the date of this prospectus. See "Underwriting."

      All of the shares of common stock being sold in this offering will be
freely tradeable without restriction or further registration under the
Securities Act, except for shares held by our "affiliates," as defined in Rule
144 under the Securities Act, which may generally only be sold in compliance
with the limitation of Rule 144, described below. The remaining 19,106,416
shares were issued and sold by us in private transactions and are deemed
restricted securities under Rule 144. These shares may be sold in the public
market only if registered under the Securities Act or if exempt from
registration under Rules 144, 144(k) or 701 under the Securities Act, which
rules are summarized below. Subject to the agreements between our shareholders
and the underwriters, described above, and the provisions of Rules 144, 144(k)
and 701, additional shares will be available for sale in the public market,
subject in the case of shares held by affiliates to compliance with volume
restrictions, as follows:

         -           shares will be available for immediate sale in the public
           market on the date of this prospectus;

         - no shares will be available for sale beginning 90 days after the date
           of this prospectus; and

         - 37,739,356 shares will be available for sale under Rules 144 and 701
           upon the expiration of agreements between our shareholders and the
           underwriters at varying dates beginning 180 days after the date of
           this prospectus.

      In general, under Rule 144, beginning 90 days after the date of this
prospectus, a person or persons whose shares are aggregated, including an
affiliate, who has beneficially owned restricted shares for at least one year,
is entitled to sell within any three-month period a number of shares that does
not exceed the greater of 1% of the then outstanding shares of common stock,
approximately           shares immediately after this offering, or the average
weekly trading volume of our common stock on the Nasdaq National Market during
the four calendar weeks preceding the date of the sale. Sales under Rule 144
also are subject to requirements pertaining to the manner and notice of the
sales and the availability of current public information concerning Netro.

      Under Rule 144(k), a person who is not deemed to have been an affiliate of
Netro at any time during the 90 days before a sale and who has beneficially
owned the shares proposed to be sold for at least two years would be entitled to
sell these shares without regard to the requirements described above. To the
extent that shares were acquired from an affiliate of Netro, the transferee's
holding period for the purpose of effecting a sale under Rule 144(k) commences
on the date of transfer from the affiliate.

      Rule 701 provides that, beginning 90 days after the date of this
prospectus, persons other than affiliates may sell shares of common stock
acquired from us in connection with written compensatory benefit plans,
including our stock option plans, subject only to the manner of sale provisions
of Rule 144. Beginning 90 days after the date of this prospectus, affiliates may
sell these shares of common stock subject to all provisions of Rule 144 except
the one-year minimum holding period.

      Shortly after the closing of this offering, we intend to file a
registration statement on Form S-8 under the Securities Act to register all
shares of common stock issuable under the 1995 Stock Option Plan, the 1996 Stock
Option Plan, the 1997 Directors' Stock Option Plan, the 1999 Executive Stock
Plan and the 1999 Employee Stock Purchase Plan. See "Management--Stock Plans."
This Form S-8 registration statement is expected to become effective immediately
upon filing and shares covered by that registration statement will then be
eligible for sale in the public markets, subject to the Rule 144 limitations
applicable to affiliates.

      Prior to this offering, there has been no public market for our common
stock, and no predictions can be made regarding the effect, if any, that sales
of shares in the open market or the availability of shares for sale will have on
the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of our common stock in the public market could adversely
affect the prevailing market price.

      After the closing of this offering, the holders of 30,990,671 shares of
our common stock will be entitled to rights with respect to the registration of
these shares under the Securities Act. Registration of these shares under the
Securities Act would result in these shares becoming freely tradeable without
restriction under the Securities Act, except for shares purchased by affiliates,
immediately upon the effectiveness of registration. For a discussion of these
rights, see "Description of Capital Stock--Registration Rights of Certain
Holders."

</TABLE>

      Subject to the terms and conditions set forth in the purchase agreement,
each of the underwriters is committed to purchase all of the shares of our
common stock being sold pursuant to the purchase agreement if any shares of our
common stock are purchased. Under certain circumstances, under the terms of the
purchase agreement, the commitments of the non-defaulting underwriters may be
increased or the purchase agreement may be terminated. We have agreed to
indemnify the underwriters against some liabilities, including some liabilities
under the Securities Act, or to contribute to payments the underwriters may be
required to make in respect of those liabilities.

      The shares of common stock are being offered by the several underwriters,
subject to prior sale, when, as and if issued to and accepted by them, subject
to approval of certain legal matters by counsel for the underwriters and certain
other conditions. The underwriters reserve the right to withdraw, cancel or
modify such offer and to reject orders in whole or in part.

COMMISSIONS AND DISCOUNTS

      The representatives have advised us that they propose initially to offer
the shares of our common stock to the public at the initial public offering
price set forth on the cover page of this prospectus, and to certain dealers at
such price less a concession not in excess of $          per share of common
stock. The underwriters may allow, and such dealers may reallow, a discount not
in excess of $          per share of common stock on sales to certain other
dealers. After the initial public offering, the public offering price,
concession and discount may be changed.

      The following table shows the per share and total public offering price,
underwriting discount to be paid by us to the underwriters and the proceeds
before expenses to us. This information is presented assuming either no exercise
or full exercise by the underwriters of their over-allotment options.

OVER-ALLOTMENT OPTION

      We have granted to the underwriters an option, exercisable for 30 days
after the date of this prospectus, to purchase up to an aggregate of
additional shares of common stock at the public offering price set forth on the
cover of this prospectus, less the underwriting discount. The underwriters may
exercise this option solely to cover over-allotments, if any, made on the sale
of our common stock offered hereby. To the extent that the underwriters exercise
this option, each underwriter will be obligated, subject to certain conditions,
to purchase a number of additional shares of our common stock proportionate to
such underwriter's initial amount reflected in the foregoing table.

DIRECTED SHARES

      At our request, the underwriters have reserved approximately
          shares of our common stock for sale at the public offering price to
our directors, consultants and certain other persons with relationships to
Netro. The number of shares of our common stock available for sale to the
general public will be reduced to the extent such persons purchase such reserved
shares. Any reserved shares which are not so orally confirmed for purchase
within one day of the pricing of the offering will be offered by the
underwriters to the general public on the same basis as the other shares offered
by this prospectus.

NO SALES OF SIMILAR SECURITIES

      We, our executive officers and directors, and most of our existing
shareholders have agreed, with certain exceptions, not to directly or
indirectly:

         - offer, pledge, sell, contract to sell, sell any option or contract to
           purchase, purchase any option or contract to sell, grant any option,
           right or warrant for the sale of, or otherwise dispose of or transfer
           any shares of our common stock or any securities convertible into or
           exchangeable or exercisable for our common stock, whether now owned
           or later acquired by the person executing the agreement or with
           respect to which the person executing the agreement later acquires
           the power of disposition, or file any registration statement under
           the Securities Act relating to any shares of our common stock for a
           period of 180 days after the date of this prospectus; or

         - enter into any swap or other agreement that transfers, in whole or in
           part, directly or indirectly, the economic consequence of ownership
           of our common stock, whether any such swap or transaction is to be
           settled by delivery of our common stock or other securities, in cash
           or otherwise, without the prior written consent of Merrill Lynch on
           behalf of the underwriters for a period of 180 days after the date of
           this prospectus. See "Shares Eligible for Future Sale."

QUOTATION ON THE NASDAQ NATIONAL MARKET

      Before this offering, there has been no public market for our common
stock. The initial public offering price will be determined through negotiations
among us and the representatives. Among the factors to be considered by us and
the representatives in determining the public offering price of our common
stock, in addition to prevailing market conditions, will be the trading
multiples of publicly traded companies that the representatives believe to be
comparable to us, certain of our financial information, the history of, and the
prospects for, our company and the industry in which we compete, and an
assessment of our management, our past and present operations, the prospects
for, and timing of, our future revenue, the present state of our development,
the percentage interest of Netro being sold as compared to the valuation for the
entire company and the above factors in relation to market values and various
valuation measures of other companies engaged in activities similar to ours.
There can be no assurance that an active trading market will develop for our
common stock or that our common stock will trade in the public market subsequent
to the offering at or above the public offering price.

      We have applied for a listing of our common stock on the Nasdaq National
Market under the symbol "NTRO."

                                       61
<PAGE>   66

      The underwriters have advised us that they do not expect sales to accounts
over which the underwriters exercise discretionary authority to exceed five
percent of the total number of shares of our common stock offered by them.

PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS

      Until the distribution of our common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
certain selling group members to bid for and purchase our common stock. As an
exception to these rules, the representatives are permitted to engage in certain
transactions that stabilize the price of our common stock. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of our common stock.

      If the underwriters create a short position in our common stock in
connection with the offering, that is, if they sell more shares of common stock
than are set forth on the cover page of this prospectus, the representatives may
reduce that short position by purchasing common stock in the open market. The
representatives may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.

      The representatives may also impose a penalty bid on certain underwriters
and selling group members. This means that, if the representatives purchase
shares of our common stock in the open market to reduce the underwriters' short
position or to stabilize the price of our common stock, they may reclaim the
amount of the selling concession from the underwriters and selling group members
that sold those shares as part of the offering.

      In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of our common stock to the extent that it
discourages resales of our common stock.

      Neither we nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of our common stock. In addition, neither
we nor any of the underwriters makes any representation that the representatives
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of Netro Corporation:

     We have audited the accompanying consolidated balance sheets of Netro
Corporation (a California corporation) and subsidiaries as of December 31, 1997
and 1998, and the related consolidated statements of operations and
comprehensive loss, shareholders' equity and cash flows for each of the three
years in the period ended December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Netro Corporation and
subsidiaries as of December 31, 1997 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (INFORMATION AS OF MARCH 31, 1999 IS UNAUDITED)

1.  ORGANIZATION AND OPERATIONS OF THE COMPANY:

     Netro Corporation (the "Company") was incorporated in California on
November 14, 1994 to develop, manufacture and sell broadband wireless access
systems.

     During 1997, the Company commenced volume shipments of its products and
emerged from the development stage. Although no longer in the development stage,
the Company continues to be subject to a number of risks similar to other
companies in a comparable stage of development, including reliance on key
personnel, successful marketing of its products in an emerging market,
competition from substitute products and other companies, successful development
of new products and the ability to secure adequate financing to support future
growth.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

UNAUDITED INTERIM FINANCIAL DATA

     The unaudited interim consolidated financial statements for the three
months ended March 31, 1998 and 1999, were prepared on the same basis as the
audited consolidated financial statements and, in the opinion of management,
include all adjustments (consisting only of normal recurring adjustments)
necessary to present fairly the financial information set forth therein, in
accordance with generally accepted accounting principles.

PRINCIPLES OF CONSOLIDATION

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

FOREIGN CURRENCY TRANSLATION

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

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

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

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

CASH AND CASH EQUIVALENTS

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

SHORT-TERM INVESTMENTS

     The Company classifies its investments in debt securities as
"held-to-maturity." Accordingly, these investments, which mature at various
dates through August 1999, are valued using the amortized cost

method. The fair value of the investments approximates amortized cost and, as
such, the gross unrealized holding gains and losses at December 31, 1997 and
1998 were not material.

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

     Approximately $12,050,000 and $4,971,000 of the total investments in debt
securities as of December 31, 1997 and 1998, respectively, are included in cash
and cash equivalents. The remaining balance is classified as short-term
investments.

</TABLE>

EQUIPMENT AND LEASEHOLD IMPROVEMENTS

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

SOFTWARE DEVELOPMENT COSTS

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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

REVENUE RECOGNITION

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

RESEARCH AND DEVELOPMENT

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

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

     Historical net loss per share was calculated under SFAS No. 128, "Earnings
per Share." Basic and diluted net loss per share on a historical basis is
computed using the weighted average number of shares of common stock
outstanding. Potential common shares from conversion of convertible preferred
stock, stock options and warrants are excluded from diluted net loss per share
as they are antidilutive. The total number of shares excluded from diluted net
loss per share relating to these securities was 22,260,942 shares, 29,777,846
shares, and 32,453,093 shares for 1996, 1997 and 1998, respectively, and
33,481,134 shares and 33,946,641 shares for the three months ended March 31,
1998 and 1999, respectively.

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

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

COMPREHENSIVE LOSS

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

STOCK-BASED COMPENSATION PLANS

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

ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," which requires
companies to value derivative financial instruments, including those used for
hedging foreign currency exposures, at current market value with the impact of
any change in market value being charged against earnings in each period. SFAS
No. 133 will be effective for and adopted by the Company in the first quarter of
the fiscal year ending December 31, 2000. The Company anticipates that SFAS No.
133 will not have a material impact on its consolidated financial statements. To
date, the Company has not entered into any derivative financial instrument
contracts.

3.  CONCENTRATIONS OF CREDIT RISK:

     Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of trade receivables and cash
investments. As of December 31, 1998 and March 31, 1999, approximately 71% and
71%, respectively, of the Company's trade accounts receivable balance was
represented by two customers. The Company does not require collateral on
accounts receivable, as the majority of the Company's customers are large,
well-established companies. The Company provides reserves for credit losses and
such losses are insignificant in all periods presented in the accompanying
consolidated financial statements. With respect to cash investments, the Company
has cash investment policies that limit the amount of credit exposure to any one
issuer and restrict placement of these investments to issuers evaluated as
credit worthy.

     Equipment and leasehold improvements consisted of the following (in

     In January 1998, the Company entered into a new bank line of credit under
which up to $6,000,000 is available for borrowings and letters of credit. This
arrangement was renewed in January 1999 and expires in January 2000. Borrowings
are limited to an aggregate amount equaling approximately 80% and 90% of
domestic and foreign eligible trade accounts receivables, respectively, and 50%
of eligible foreign inventories. The line of credit is secured by the Company's
outstanding trade accounts receivable and inventory. The borrowings under the
line are due in January 2000 and accrue interest at the 30-day LIBOR rate plus
2.25% or the bank's prime rate, at the Company's option. Under the agreement,
the Company must comply with certain financial and other covenants. As of
December 31, 1998, borrowings outstanding under this agreement were $1,839,000
and amounts utilized for outstanding letters of credit were $500,000. Through
the three months ended March 31, 1999, the Company borrowed an additional
$1,035,000 under the existing bank line of credit.

     In 1997, the Company borrowed $3,750,000 from a lender to finance purchases
of fixed assets. The loan accrues interest at 12.5% per annum from the date of
borrowing, and is secured by a purchase money lien on the equipment financed.
Principal payments due under the loan at December 31, 1998 are as follows (in
thousands):

</TABLE>

     Rent expense for the operating leases was approximately $224,000, $538,000
and $922,000 in 1996, 1997 and 1998, respectively.

     The Company issued a standby letter of credit of $500,000 to secure certain
of the Company's warranty obligations to one customer related to possible
damages resulting from downtime due to product performance issues. The letter of
credit is secured by a certificate of deposit for $125,000. The letter of credit
is subject to draw if the Company fails to meet its obligation for liquidated
damages to the customer.

CONTINGENCIES

     In March 1999, one of the Company's former contract manufacturers filed for
binding arbitration in Santa Clara County, California with respect to a dispute
with the Company. The arbitration involves claims for approximately $950,000 for
amounts allegedly owed by the Company for inventory purchased by the plaintiff
in anticipation of the Company's projected demand. In June 1999, the Company
filed an answer and counterclaim alleging damages of approximately $275,000 for
product failures. The Company believes it has meritorious defenses to its claim,
and intends to defend this arbitration vigorously.

8.  EMPLOYEE BENEFIT PLAN:

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

9.  CAPITAL STOCK:

STOCK SPLIT

     In December 1996, the Company's Board of Directors effected a two-for-one
stock split payable in the form of a dividend of one additional share of the
Company's capital stock for every share owned by shareholders. Accordingly, all
share data was adjusted to retroactively reflect the stock split.

CAPITAL STOCK

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

     At December 31, 1998, 33,014,597 shares of Common Stock were reserved,
including 5,244,615 shares for issuance under the Company's stock option plans,
27,732,235 shares for conversion of the outstanding Convertible Preferred Stock
and 37,747 for Convertible Preferred Stock warrants.

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

STOCK OPTION PLANS

  1997 Directors' Stock Option Plan

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

  1995 and 1996 Stock Option Plans

     During 1996, the Company established the 1996 Stock Option Plan (the "1996
Plan"). All shares previously available for issuance under the Company's 1995
Stock Option Plan are reserved for issuance under the 1996 Plan. As of December
31, 1998, 6,679,716 shares of Common Stock have been reserved for issuance under
the 1996 Plan. Under the 1996 Plan, the Company may grant incentive stock
options or nonstatutory stock options to employees, officers, directors and
consultants at an exercise price of not less than 100% of the fair market value
of the Common Stock on the date of grant, except that nonstatutory stock options
may be granted at 85% of such fair market value. Options granted generally
become exercisable at a rate of one-fourth of the shares subject to the option
at the end of the first year and 1/48 of the shares subject to the option at the
end of each calendar month thereafter. However, at the discretion of management,
the optionee may have the immediate right to exercise the option subject to a
restricted stock agreement that gives the Company the right to repurchase
unvested shares at the original issuance price in the event of termination of
employment. The maximum term of a stock option under the plans is ten years, but
if the optionee at the time of grant has voting power of more than 10% of the
Company's outstanding capital stock, the maximum term is five years.

     The following table summarizes option activity under all option plans:

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

     The weighted average fair values of options granted during 1996, 1997 and
1998 were $0.58, $2.47 and $2.48 per share, respectively. The fair value of each
option grant was estimated on the date of grant using the Black-Scholes option
valuation model with the following assumptions:

DEFERRED STOCK COMPENSATION (UNAUDITED)

     In connection with the grant of stock options to purchase 2,223,050 shares
of common stock with a weighted average exercise price of $2.00 per share to
employees during 1998 and the three months ended March 31, 1999, the Company
recorded deferred compensation of $2,123,000, representing the difference
between the estimated fair value of the common stock and the option exercise
price of such options at the date of grant. Such amount is presented as a
reduction of shareholders' equity and amortized ratably over the vesting period
of the applicable options (generally four years). Amortization expense related
to fiscal 1998 was immaterial. Amortization expense of $168,000 was recorded
during the three months ended March 31, 1999. Compensation expense is decreased
in the period of forfeiture for any accrued but unvested compensation arising
from the early termination of an option holder's services.

     In April and May of 1999, the Company recorded an additional $3,725,000 of
deferred stock compensation in connection with the grant of additional options

     The rights and preferences of the Series A, B, C and D Convertible
Preferred Stock are as follows:

     - The holders of Series A, B, C and D Preferred Stock are entitled to
       dividends of $0.036, $0.16, $0.56 and $0.62 per share, respectively,
       payable annually, as and if declared by the Board of Directors. Dividends
       declared are prior and in preference to payment of dividends on Common
       Stock. No dividends had been declared as of December 31, 1998.

     - In the event of a liquidation or winding up of the Company, the holders
       of Series A, B, C and D Preferred Stock shall be entitled to receive, in
       preference to holders of Common Stock, an amount that is equal to $0.45,
       $2.00, $7.00 and $7.78 per share, respectively, plus any declared but
       unpaid dividends on such shares. If amounts are not available to satisfy
       the full preferential amounts, the entire assets of the Company will be
       distributed to the preferred shareholders in proportion to the aggregate
       liquidation preferences of the shares of Preferred Stock held.

     - Each share of Preferred Stock is convertible, at the option of the holder
       at any time after the date of issuance of such shares, into Common Stock
       at the initial conversion rate of one fully paid and non-assessable share
       of Common Stock. The conversion rate is subject to adjustments upon the
       occurrence of certain events.

     - Each share of Preferred Stock will convert into shares of Common Stock
       immediately upon the consummation of an underwritten public offering
       pursuant to an effective registration statement under the Securities Act
       of 1933.

     - Each holder of Preferred Stock has the right to one vote for each share
       of Common Stock into which the Preferred Stock could then be converted.
       Holders of Preferred Stock vote with holders of Common Stock except (i)
       on matters required by law or otherwise to be voted upon by class and
       (ii) for the election of members of the Board of Directors. Holders of
       Preferred Stock as a group are entitled to elect three members of the
       Board of Directors.

     - Holders of at least a majority of the Preferred Stock are required to
       consent to any action that: (i) alters or changes the rights, preferences
       or privileges of that class of Preferred Stock; (ii) increases the
       authorized number of shares of Preferred Stock; (iii) creates any class
       of stock with preferences or priorities superior to or on a parity with
       the preferences and priority of the Preferred Stock; or (iv) affects the
       sale of all or substantially all of the assets of the Company, or any
       consolidation or merger, or any sale of more than 50% of the Company's
       capital stock.

     In connection with one of the Company's capital lease financing
arrangements, the Company issued warrants to its lessor as follows:

Series D Preferred Stock...............................   1998      8,997      $7.78
</TABLE>

     The warrants are exercisable immediately upon issuance and expire two years
from the closing of an initial public offering or five years from the date the
warrants were granted, whichever is later. The fair value of the warrants was
estimated at the date of grant using the Black-Scholes model and the value was
determined to be immaterial.

     In March 1999, as part of a new equipment loan agreement, the Company
issued warrants to purchase 19,281 shares of Series D Preferred Stock at an
exercise price of $7.78 per share. The warrants are exercisable immediately upon
issuance and expire three years from the closing of an initial public offering
or seven years from the date the warrants were granted, whichever is later. The
fair value of the warrants was estimated at the date of grant using the
Black-Scholes model and the value was determined to be immaterial.

PRO FORMA SHAREHOLDERS' EQUITY (UNAUDITED)

     In May 1999, the Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission to register shares of the
Company's Common Stock in connection with a proposed initial public offering
("IPO"). If the offering is consummated under the terms presently anticipated,
all of the currently outstanding Convertible Preferred Stock will convert to
29,250,875 shares of common stock upon the closing of the IPO. The effect of
this conversion has been reflected as unaudited pro forma shareholders' equity
in the accompanying consolidated balance sheet as of March 31, 1999.

10.  INCOME TAXES:

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

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

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

     As of December 31, 1998, the Company had Federal and State net operating
loss carryforwards of approximately $59,891,000 and $20,160,000, respectively.
The Company's net operating loss carryforwards expire at various dates through
2018. Under current tax law, the net operating loss and tax credit carryforwards
available for use in any given year may be limited upon the occurrence of
certain events, including significant changes in ownership interest.

11.  SEGMENT REPORTING

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

     The Company markets its products in the United States and in other foreign
countries through worldwide system integrators, its direct sales force and local
resellers. Revenue by country was as follows:

12.  SUBSEQUENT EVENTS:

     In April and June 1999, the Company issued 630,614 additional shares of
Series D Convertible Preferred Stock at $7.78 per share for net proceeds of
approximately $4,906,000.

     In January 1999, the Company entered into an agreement with one of its
vendors to issue up to approximately 100,000 shares of Preferred Stock for
engineering work performed. The number of shares to be issued will be determined
by dividing the dollar amount specified for the achievement of agreed-upon
milestones by the price per share of such series of Preferred Stock most
recently issued. In June 1999, the Company issued 20,794 shares of Series D
Convertible Preferred Stock pursuant to the terms of this agreement.

     In April 1999, the Board of Directors approved the 1999 Executive Stock
Plan (the "Executive Plan"). A total of 1,195,000 shares of common stock were
reserved for issuance under the plan. In June 1999, options to purchase
1,195,000 shares of common stock at an exercise price of $3.50 per share had
been issued under the Executive Plan and no further options will be granted.

     In April 1999, the Board of Directors approved an increase in the total
number of shares of Common Stock reserved for issuance under the 1996 Stock
Option Plan of 2,120,284 shares.

     In June 1999, the Board of Directors adopted the 1999 Employee Stock
Purchase Plan (the "Purchase Plan"). The Purchase Plan is intended to qualify
under Section 423 of the Internal Revenue Code. A total of 1,000,000 shares of
common stock have been reserved for issuance under the Purchase Plan. The price
of shares purchased under the plan will be equal to 85% of the fair market value
of the Common Stock on the first or last day of the offering period, whichever
is lower.

aggregate capacity of over 600 Mbps.

5. On the Left-hand Side:

   - Service Integration and Bandwidth on Demand. Service Providers using
     AirStar's intelligent wireless transport can support both voice and
     high-speed packet data services on the same system, enabling them to
     increase revenue from their licensed spectrum.

  - Cost Effective Deployment and Operation. AirStar allows competitive service
    providers to compete effectively in the broadband access market because it
    is designed to provide for low overall system costs and enable success-based
    capital deployment by directly linking network buildout expenditures to
    subscriber growth. Additionally, AirStar's statistical multiplexing allows a
    service provider to optimize spectrum use and equipment deployment by
    expanding effective transmission capacity.

  - Quality of Service. Using our AirStar system, service providers can deploy
    voice and high-speed packet data services at different price points to
    different market segments with the option for guaranteed quality of service
    levels and up to 99.999% availability. These capabilities allow a service
    provider to match and guarantee delivered bandwidth to a particular
    business' requirements and budget.

  - Rapid Time to Market. Service providers using AirStar can achieve rapid time
    to market for integrated voice and high speed data services through
    AirStar's efficient installation, end-to-end network management integration
    and intelligent wireless transport. By installing a single AirStar base
    station, the service provider can attain coverage of many potential
    subscribers.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 317 of the California General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Act").
Article VI of the Registrant's Amended and Restated Articles of Incorporation,
to be filed and effective upon completion of this offering (Exhibit 3.3 hereto),
provides for indemnification of its directors and officers to the maximum extent
permitted by the California General Corporation Law and Section 6.1 of the
Registrant's Bylaws, to be filed and effective upon completion of this offering
(Exhibit 3.4 hereto), provides for indemnification of its directors, officers,
employees and other agents to the maximum extent permitted by the California
General Corporation Law. In addition, the Registrant has entered into
Indemnification Agreements (Exhibit 10.1 hereto) with its directors and officers
containing provisions that are in some respects broader than the specific
indemnification provisions contained in the California General Corporation Law.
The indemnification agreements may require the Registrant, among other things,
to indemnify its directors against certain liabilities that may arise by reason
of their status or service as directors (other than liabilities arising from
willful misconduct of culpable nature), to advance their expenses incurred as a
result of any proceeding against them as to which they could be indemnified, and
to obtain directors' insurance if available on reasonable terms. Reference is
also made to Section 6(b) of the Underwriting Agreement contained in Exhibit 1.1
hereto, indemnifying officers and directors of the Registrant against certain
liabilities.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES

with any distribution thereof and appropriate legends affixed to the securities
issued in such transactions. All recipients had adequate access, through their
relationships with the Registrant, to information about the Registrant.

ITEM 17.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Act, the
     information omitted from the form of Prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in the form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act shall be deemed to be a part of this Registration
     Statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Act, each
     post-effective amendment that contains a form of Prospectus shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE

To the Board of Directors and Shareholders of
Netro Corporation:

     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Netro Corporation (a California
corporation) and subsidiaries included in this registration statement and have
issued our report thereon dated March 4, 1999. Our audits were made for the
purpose of forming an opinion on the basic financial statements taken as a
whole. The schedule listed in the exhibit index above is the responsibility of
the Company's management, is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

                                NETRO CORPORATION

      The undersigned, Gideon Ben-Efraim and Tae Hea Nahm certify that:

      1. They are the duly elected President and Secretary of Netro Corporation,
a California corporation.

      2. The Articles of Incorporation of this corporation are amended and
restated to read in full as follows:

                                       "I

      The name of this corporation is Netro Corporation.

                                       II

      The purpose of this corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                       III

      (A) Classes of Stock. This corporation is authorized to issue two classes
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
The total number of shares which the corporation is authorized to issue is
92,692,517 shares, of which 60,000,000 shares shall be Common Stock and
32,692,517 shares shall be Preferred Stock, each with a par value of $0.001.

      (B) Rights, Preferences and Restrictions of Preferred Stock. The Preferred
Stock authorized by these Articles of Incorporation may be issued from time to
time in series. The first series of Preferred Stock shall be designated "Series
A Preferred Stock" and shall consist of 13,466,660 shares. The second series of
Preferred Stock shall be designated "Series B Preferred Stock" and shall consist
of 5,250,000 shares. The third series of Preferred Stock shall be designated
"Series C Preferred Stock" and shall consist of 8,475,857 shares. The fourth
series of Preferred Stock shall be designated "Series D Preferred Stock" and
shall consist of 5,500,000 shares. The rights, preferences, privileges, and
restrictions granted to and imposed on the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock are as
follows:

<PAGE>   2
            (1) Dividends.

                  (aa) The holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall be
entitled to receive in any fiscal year, when and as declared by the Board of
Directors, out of any assets at the time legally available therefor, dividends
in cash at the rate of $0.036, $0.160, $0.560 and $0.618, respectively, per
share per annum, before any cash dividend is paid on Common Stock. Such
dividends or distributions may be payable annually or otherwise as the Board of
Directors may from time to time determine. Dividends or distributions (other
than dividends payable solely in shares of Common Stock) may be declared and
paid upon shares of Common Stock in any fiscal year of the corporation only if
dividends shall have been paid on or declared and set apart upon all shares of
the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
and Series D Preferred Stock at the respective annual rates prescribed herein;
and no further dividends shall be paid to holders of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock in excess of such annual rates in any fiscal year unless at the
same time equivalent dividends are paid to holders of shares of Common Stock.
The right to such dividends on shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock shall not
be cumulative and no right shall accrue to holders of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock by reason of the fact that dividends on said shares are not
declared in any prior year, nor shall any undeclared or unpaid dividend bear or
accrue interest.

                  (bb) In the event this corporation shall declare a
distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (including cash dividends in
excess of the amount paid in such fiscal year to holders of shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock) or options or rights to purchase any such securities or
evidences of indebtedness, then, in each such case the holders of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though the holders of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock were the
holders of the number of shares of Common Stock of the corporation into which
their respective shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock are convertible as of the
record date fixed for the determination of the holders of Common Stock of the
corporation entitled to receive such distribution.

            (2) Voting Rights.

                  (aa) In General. Subject to subsection (bb) hereof and except
as otherwise required by law, the holders of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock and the
holders of Common


                                      -2-
<PAGE>   3
Stock shall be entitled to notice of any shareholders' meeting and to vote
together as a single class upon any matter submitted to the shareholders for a
vote, as follows: (A) each holder of Series A Preferred Stock shall have one
vote for each full share of Common Stock into which its shares of Series A
Preferred Stock would be convertible on the record date for the vote, (B) each
holder of Series B Preferred Stock shall have one vote for each full share of
Common Stock into which its shares of Series B Preferred Stock would be
convertible on the record date for the vote, (C) each holder of Series C
Preferred Stock shall have one vote for each full share of Common Stock into
which its shares of Series C Preferred Stock would be convertible on the record
date for the vote, (D) each holder of Series D Preferred Stock shall have one
vote for each full share of Common Stock into which its shares of Series D
Preferred Stock would be convertible on the record date for the vote and (E) the
holders of Common Stock shall have one vote per share of Common Stock.

                  (bb) Voting for Board of Directors. The Board of Directors of
this corporation shall consist of seven members. The holders of shares of Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series
D Preferred Stock, voting together as a single class, shall elect three members
of the Board of Directors of the corporation. The holders of shares of Common
Stock, voting separately as a class, shall elect three members of the Board of
Directors of the corporation. The remaining member of the Board of Directors
shall be elected by the holders of shares of Common Stock, Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock, voting together as a single class. If a vacancy on the Board of Directors
is to be filled by the Board of Directors, only a director or directors elected
by the same class of shareholders as those who would be entitled to vote to fill
such vacancy, if any, shall vote to fill such vacancy. No action by members of
the Board of Directors filling a vacancy on the Board of Directors shall be
effective until 10 days after all Board members who do not have a right to vote
on such appointment have received notice thereof. A majority of the Board
members entitled to receive such notice may waive such notice requirement on
behalf of all such Board members. A director may be removed from the Board of
Directors with or without cause by the vote or consent of the holders of the
outstanding class or series with voting power to elect him or her in accordance
with the California General Corporation Law and these Articles of Incorporation.

                  (3) Conversion. The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

                  (aa) Right to Convert.

                        (i) Each share of Series A Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Series A Preferred Stock, into Common Stock at the initial conversion
rate of one fully paid and non-assessable share of Common Stock for each share
of Series A Preferred Stock,


                                      -3-
<PAGE>   4
subject, however, to the adjustments described below. (The number of shares of
Common Stock into which each share of Series A Preferred Stock may be converted
is hereafter referred to as the "Series A Conversion Rate.")

                        (ii) Each share of Series B Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Series B Preferred Stock, into Common Stock at the initial conversion
rate of one fully paid and non-assessable share of Common Stock for each share
of Series B Preferred Stock, subject, however, to the adjustments described
below. (The number of shares of Common Stock into which each share of Series B
Preferred Stock may be converted is hereafter referred to as the "Series B
Conversion Rate.")

                        (iii) Each share of Series C Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Series C Preferred Stock, into Common Stock at the initial conversion
rate of one fully paid and non-assessable share of Common Stock for each share
of Series C Preferred Stock, subject, however, to the adjustments described
below. (The number of shares of Common Stock into which each share of Series C
Preferred Stock may be converted is hereafter referred to as the "Series C
Conversion Rate.")

                        (iv) Each share of Series D Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the corporation or any transfer agent
for the Series D Preferred Stock, into Common Stock at the initial conversion
rate of one fully paid and non-assessable share of Common Stock for each share
of Series D Preferred Stock, subject, however, to the adjustments described
below. (The number of shares of Common Stock into which each share of Series D
Preferred Stock may be converted is hereafter referred to as the "Series D
Conversion Rate.")

                        (v) No fractional shares of Common Stock shall be issued
upon conversion of the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock and any shares of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock surrendered for conversion which would otherwise result in a
fractional share of Common Stock shall be redeemed for the then fair market
value thereof as determined by the corporation's Board of Directors, payable as
promptly as possible whenever funds are legally available therefor. If more than
one share of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock is surrendered for conversion at any
one time by the same holder, the number of full shares of Common Stock to be
issued upon conversion shall be computed on the basis of the aggregate number of
shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred
Stock or Series D Preferred Stock so surrendered.


                                      -4-
<PAGE>   5
                        (vi) Automatic Conversion. Each share of Preferred Stock
of any series shall automatically be converted into shares of Common Stock at
the then effective Conversion Rate for that series (A) in the event of, and
contingent upon, the consummation of a firm commitment underwritten public
offering pursuant to an effective registration statement under the Securities
Act of 1933, as amended, covering the offer and sale of Common Stock for the
account of the corporation to the public, resulting in gross proceeds to the
Company of at least $10,000,000 and at a price per share no less than the fair
market value (as determined in good faith by the Company's Board of Directors)
of a share of the Company's Common Stock as of the date thereof, or (B) by
consent of the holders of not less than a majority in voting interest of the
then outstanding shares of Preferred Stock.

                  (bb) Mechanics of Conversion. Before any holder of Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or Series D
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, such holder shall surrender the certificate or certificates therefor,
duly endorsed, at the office of the corporation or of any transfer agent for the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock or
Series D Preferred Stock, as applicable, and shall give written notice to the
corporation at such office that such holder elects to convert the same and shall
state therein the name or names in which such holder wishes the certificate or
certificates for the number of shares of Common Stock to be issued. The
corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock or Series D Preferred Stock, or to such holder's
nominee or nominees, a certificate or certificates for the number of shares of
Common Stock to which such holder shall be entitled as aforesaid. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock to be converted, and the person or persons entitled to receive the shares
of Common Stock issuable upon such conversion shall be treated for all purposes
as the record holder or holders of such shares of Common Stock on such date.

                  (cc) Adjustment of Conversion Rate For Combinations or
Consolidations of Common Stock. In the event the corporation, at any time or
from time to time after the effective date of a written agreement by the
corporation for the initial sale of Preferred Stock (hereinafter referred to as
the "Original Issue Date"), effects a subdivision or combination of its
outstanding Common Stock into a greater or lesser number of shares without a
proportionate and corresponding subdivision or combination of its outstanding
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, then and in each such event the Series A Conversion
Rate, Series B Conversion Rate, Series C Conversion Rate and Series D Conversion
Rate shall be increased or decreased proportionately.

                  (dd) Adjustments for Reorganization, Reclassification,
Exchange and Substitution. If the Common Stock issuable upon conversion of the
Series


                                      -5-
<PAGE>   6
A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series
D Preferred Stock shall be changed into the same or a different number of shares
of any other class or classes of stock or other securities or property, whether
by reorganization (unless such reorganization is deemed a liquidation under
Section 4(bb) hereof), reclassification or otherwise (other than a subdivision
or combination of shares provided for above), the Series A Conversion Rate,
Series B Conversion Rate, Series C Conversion Rate and Series D Conversion Rate
then in effect shall, concurrently with the effectiveness of such reorganization
or reclassification, be proportionately adjusted such that the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock shall be convertible into, in lieu of the number of shares of
Common Stock which the holders would otherwise have been entitled to receive, a
number of shares of such other class or classes of stock or other securities or
property equivalent to the number of shares of Common Stock that would have been
subject to receipt by the holders upon conversion of the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock, respectively, immediately before such event; and, in any such case,
appropriate adjustment shall be made in the application of the provisions herein
set forth with respect to the rights and interest thereafter of the holders of
the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
and Series D Preferred Stock, to the end that the provisions set forth herein
(including provisions with respect to changes in and other adjustments of the
Series A Conversion Rate, Series B Conversion Rate, Series C Conversion Rate and
Series D Conversion Rate) shall thereafter be applicable, as nearly as
reasonably may be, in relation to any shares of stock or other property
thereafter deliverable upon the conversion of the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock.

                  (ee) Adjustment of Conversion Rate for Dividends,
Distributions and Common Stock Equivalents. In the event the corporation at any
time or from time to time after the Original Issue Date shall make or issue, or
fix a record date for the determination of holders of Common Stock entitled to
receive a dividend or other distribution payable in additional shares of Common
Stock or other securities or rights (hereinafter referred to as "Common Stock
Equivalents") convertible into or entitling the holder thereof to receive
additional shares of Common Stock without payment of any consideration by such
holder for such Common Stock Equivalents or the additional shares of Common
Stock, then and in each such event the maximum number of shares (as set forth in
the instrument relating thereto without regard to any provisions contained
therein for a subsequent adjustment of such number) of Common Stock issuable in
payment of such dividend or distribution or upon conversion or exercise of such
Common Stock Equivalents shall be deemed to be issued and outstanding as of the
time of such issuance or, in the event such a record date shall have been fixed,
as of the close of business on such record date. In each such event, the Series
A Conversion Rate, Series B Conversion Rate, Series C Conversion Rate and Series
D Conversion Rate for the Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock, respectively, shall be
increased as of the time of such issuance or, in the event such a record date
shall have been fixed, as of the close of business on such record


                                      -6-
<PAGE>   7
date, by multiplying the Series A Conversion Rate, Series B Conversion Rate,
Series C Conversion Rate or Series D Conversion Rate, as applicable, by a
fraction,

                        (i) the numerator of which shall be the total number of
shares of Common Stock issued and outstanding or deemed to be issued and
outstanding immediately prior to the time of such issuance on the close of
business on such record date plus the number of shares of Common Stock issuable
in payment of such dividend or distribution or upon conversion or exercise of
such Common Stock Equivalents and

                        (ii) the denominator of which shall be the total number
of shares of Common Stock issued and outstanding or deemed to be issued and
outstanding immediately prior to the time of such issuance on the close of
business on such record date provided, however, (A) if such record date shall
have been fixed and such dividend is not fully paid or if such distribution is
fully made on the date fixed therefor, the Series A Conversion Rate, Series B
Conversion Rate, Series C Conversion Rate and Series D Conversion Rate shall be
recomputed accordingly as of the close of business on such record date and
thereafter the Series A Conversion Rate, Series B Conversion Rate, Series C
Conversion Rate and Series D Conversion Rate shall be adjusted pursuant to this
paragraph (B)(3)(ee) as of the time of actual payment of such dividends or
distribution; (B) if such Common Stock Equivalents provide, with the passage of
time or otherwise, for any decrease in the number of shares of Common Stock
issuable upon conversion or exercise thereof, the Series A Conversion Rate,
Series B Conversion Rate, Series C Conversion Rate and Series D Conversion Rate
for such series shall, upon any such decrease becoming effective, be recomputed
to reflect such decrease insofar as it affects the rights of conversion or
exercise of the Common Stock Equivalents then outstanding; and (C) upon the
expiration of any rights of conversion or exercise under any unexercised Common
Stock Equivalents, the Series A Conversion Rate, Series B Conversion Rate,
Series C Conversion Rate and Series D Conversion Rate computed upon the original
issue thereof shall, upon such expiration, be recomputed as if the only
additional shares of Common Stock issued were the shares of such stock, if any,
actually issued upon the conversion or exercise of such Common Stock
Equivalents.

                  (ff) No Impairment. The corporation will not, by amendment of
its Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of this paragraph (B)(3) and in the taking of all such action as may be
necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock against impairment.

                  (gg) Certificate as to Adjustments. Upon the occurrence of
each adjustment or readjustment of the Series A Conversion Rate, Series B
Conversion Rate, Series C Conversion Rate or Series D Conversion Rate pursuant
to this paragraph (B)(3),


                                      -7-
<PAGE>   8
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of affected Preferred Stock a certificate setting forth such adjustment
or readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, Series B Preferred Stock, Series
C Preferred Stock and Series D Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Series A Conversion Rate, Series B Conversion Rate,
Series C Conversion Rate or Series D Conversion Rate at the time in effect, as
appropriate, and (iii) the number of shares of Common Stock and the amount, if
any, of the property which at the time would be received upon the conversion of
such holder's shares of Series A Preferred Stock, Series B Preferred Stock,
Series C Preferred Stock and Series D Preferred Stock.

                  (hh) Notices of Record Date. In the event of the establishment
by the corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any Common Stock
Equivalents or any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to receive
any other right, the corporation shall mail to each holder of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock, at least twenty (20) days prior to the date specified therein, notice
specifying the date on which any such record is to be taken for the purpose of
such dividend, distribution or right, and the amount and character of such
dividend, distribution or right.

                  (ii) Reservation of Stock Issuable Upon Conversion. The
corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series D Preferred Stock such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all then outstanding shares of the Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock;
and if at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of all of the then outstanding
shares of the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock, the corporation will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purpose.

                  (jj) Notices. Any notices required by the provisions of this
paragraph (B)(3) to be given to the holders of shares of Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock or Series D Preferred
Stock shall be deemed


                                      -8-
<PAGE>   9
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at such holder's address appearing on the books of the
corporation.

                  (kk)  Status of Converted Stock.  All converted shares of
Preferred Stock shall be deemed cancelled and shall not be issued again by
the Company.

            (4) Liquidation Preference.

                  (aa) In the event of any liquidation, dissolution or winding
up of the corporation, either voluntary or involuntary, the holders of the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock shall be entitled to receive, prior and in preference
to any distribution of any of the assets or surplus funds of the corporation to
the holders of the Common Stock by reason of their ownership thereof, the amount
of $0.45, $2.00, $7.00 and $7.78 per share, respectively, and in addition, an
amount equal to all declared but unpaid dividends on the Series A Preferred
Stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred
Stock respectively. If, upon the occurrence of such event, the assets and funds
thus distributed among the holders of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall be
insufficient to permit the payment to such holders of the full preferential
amount, then the entire assets and funds of the corporation legally available
for distribution shall be distributed ratably among the holders of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock as between such series, in proportion to the product of the
respective preference amount of each shares multiplied by the number of shares
of such stock owned by each such holder. After payment has been made to the
holders of the Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock of the full amounts to which they
shall be entitled as aforesaid, any remaining assets shall be distributed
ratably to the holders of the corporation's Common Stock.

                  (bb) A merger of the corporation with or into any other
corporation or corporations, or the merger of any other corporation or
corporations into the corporation, in which consolidation or merger the
shareholders of the corporation receive distributions in cash or securities of
another corporation or corporations as a result of such consolidation or merger,
or a sale of all or substantially all of the assets of the corporation, shall be
treated as a liquidation, dissolution or winding up for purposes of this
paragraph (B)(4), unless the shareholders of this corporation hold at least 50%
of the outstanding voting equity securities of the surviving corporation;
provided that nothing contained in this subsection (bb) shall limit the right of
a holder of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock or Series D Preferred Stock to convert such shares into Common
Stock prior to the effective date of any such transaction.

            (5) Protective Provisions. In addition to any other rights provided
by law, so long as 15,000,000 shares of Series A Preferred Stock, Series B
Preferred Stock,


                                      -9-
<PAGE>   10
Series C Preferred Stock and Series D Preferred Stock taken together shall be
outstanding, this corporation shall not, without first obtaining the affirmative
vote or written consent of the holders of not less than a majority in voting
interest of such outstanding shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, voting
together as a single class:

                  (aa) amend or repeal any provision of, or add any provision
to, this corporation's Articles of Incorporation or Bylaws if such action would
alter or change the preferences, rights, privileges or powers of, or the
restrictions provided for the benefit of, the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock;

                  (bb) authorize shares of any class of stock having any
preference or priority as to dividends or assets superior to or on a parity with
any such preference or priority of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock or Series D Preferred Stock, or
authorize shares of stock of any class or any bonds, debentures, notes or other
obligations convertible into or exchangeable for, or having option rights to
purchase, any shares of stock of this corporation having any preference or
priority as to dividends or assets superior to or on a parity with any such
preference or priority of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock or Series D Preferred Stock;

                  (cc) effect in any transaction or series of transactions a
sale or other conveyance of all or substantially all of the assets of the
corporation or any of its subsidiaries, or any consolidation or merger involving
the corporation or any of its subsidiaries where the corporation or such
subsidiary is not the surviving corporation, or any sale of more than 50% of the
corporation's capital stock; or

                  (dd)  increase the authorized number of shares of Preferred
Stock.

      (C) Common Stock.

            (1) Dividend Rights. Subject to the prior rights of holders of all
classes of stock at the time outstanding having prior rights as to dividends,
the holders of the Common Stock shall be entitled to receive, when and as
declared by the Board of Directors, out of any assets of the corporation legally
available therefor, such dividends as may be declared from time to time by the
Board of Directors.

            (2) Liquidation Rights. Upon the liquidation, dissolution or winding
up of the corporation, the assets of the corporation shall be distributed as
provided in paragraph III(B)(4) hereof.

            (3) Voting Rights. The holder of each share of Common Stock shall
have the right to one vote, and shall be entitled to notice of any shareholders'
meeting in


                                      -10-
<PAGE>   11
accordance with the Bylaws of this corporation, and shall be entitled to vote
upon such matters and in such manner as may be provided by law.

                                       IV

      (A) Limitation on Directors' Liability. The liability of the directors of
the corporation for monetary damages shall be eliminated to the fullest extent
permissible under California law.

      (B) Indemnification of Corporate Agents. The corporation is authorized to
provide indemnification of agents (as defined in Section 317 of the California
General Corporation law) through Bylaw provisions, agreements with agents, vote
of shareholders or disinterested directors or otherwise, in excess of the
indemnification otherwise permitted by Section 317 of the California General
Corporation law, subject only to the applicable limits set forth in Section 204
of the California General Corporation Law with respect to actions for breach of
duty to the corporation and its shareholders.

      (C) Repeal or Modification. Any repeal or modification of the foregoing
provisions of this Article IV by the shareholders of the corporation shall not
adversely affect any right or protection of a director of the corporation
existing at the time of such repeal or modification."

      3. The foregoing amendment of the Articles of Incorporation has been duly
approved by the Board of Directors.

      4. The foregoing Amended and Restated Articles of Incorporation have been
duly approved by the required vote of shareholders in accordance with Sections

                                NETRO CORPORATION


                                    ARTICLE I

                                CORPORATE OFFICES

        1.1 PRINCIPAL OFFICE

        The board of directors shall fix the location of the principal executive
office of the corporation at any place within or outside the State of
California. If the principal executive office is located outside such state and
the corporation has one or more business offices in such state, then the board
of directors shall fix and designate a principal business office in the State of
California.

        1.2 OTHER OFFICES

        The board of directors may at any time establish branch or subordinate
offices at any place or places where the corporation is qualified to do
business.


                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

        2.1 PLACE OF MEETINGS

        Meetings of shareholders shall be held at any place within or outside
the State of California designated by the board of directors. In the absence of
any such designation, shareholders' meetings shall be held at the principal
executive office of the corporation.

        2.2 ANNUAL MEETING

        The annual meeting of shareholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such
designation, the annual meeting of shareholders shall be held on the First day
of April in each year at 11:00 a.m. However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding full business day. At the meeting, directors shall be elected, and
any other proper business may be transacted.

        2.3 SPECIAL MEETING

        A special meeting of the shareholders may be called at any time by the
board of directors, or by the chairman of the board, or by the president, or by
one or more shareholders holding


<PAGE>   6
shares in the aggregate entitled to cast not less than ten percent (10%) of the
votes at that meeting.

        If a special meeting is called by any person or persons other than the
board of directors or the president or the chairman of the board, then the
request shall be in writing, specifying the time of such meeting and the general
nature of the business proposed to be transacted, and shall be delivered
personally or sent by registered mail or by telegraphic or other facsimile
transmission to the chairman of the board, the president, any vice president or
the secretary of the corporation. The officer receiving the request shall cause
notice to be promptly given to the shareholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request. If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice. Nothing contained in this paragraph of this
Section 2.3 shall be construed as limiting, fixing or affecting the time when a
meeting of shareholders called by action of the board of directors may be held.

        2.4 NOTICE OF SHAREHOLDERS' MEETINGS

        All notices of meetings of shareholders shall be sent or otherwise given
in accordance with Section 2.5 of these bylaws not less than ten (10) (or, if
sent by third-class mail pursuant to Section 2.5 of these bylaws, thirty (30))
nor more than sixty (60) days before the date of the meeting. The notice shall
specify the place, date, and hour of the meeting and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the shareholders
(but subject to the provisions of the next paragraph of this Section 2.4 any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

        If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California (the
"Code"), (ii) an amendment of the articles of incorporation, pursuant to Section
902 of the Code, (iii) a reorganization of the corporation, pursuant to Section
1201 of the Code, (iv) a voluntary dissolution of the corporation, pursuant to
Section 1900 of the Code, or (v) a distribution in dissolution other than in
accordance with the rights of outstanding preferred shares, pursuant to Section
2007 of the Code, then the notice shall also state the general nature of that
proposal.

<PAGE>   7
        2.5 MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

        Written notice of any meeting of shareholders shall be given either (i)
personally or (ii) by first-class mail or (iii) by third-class mail but only if
the corporation has outstanding shares held of record by five hundred (500) or
more persons (determined as provided in Section 605 of the Code) on the record
date for the shareholders' meeting, or (iv) by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the shareholder at the address of that shareholder
appearing on the books of the corporation or given by the shareholder to the
corporation for the purpose of notice. If no such address appears on the
corporation's books or is given, notice shall be deemed to have been given if
sent to that shareholder by mail or telegraphic or other written communication
to the corporation's principal executive office, or if published at least once
in a newspaper of general circulation in the county where that office is
located. Notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail or sent by telegram or other means of
written communication.

        If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at that address, then all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder on written demand of the shareholder at the principal executive
office of the corporation for a period of one (1) year from the date of the
giving of the notice.

        An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

        2.6 QUORUM

        The presence in person or by proxy of the holders of a majority of the
shares entitled to vote thereat constitutes a quorum for the transaction of
business at all meetings of shareholders. The shareholders present at a duly
called or held meeting at which a quorum is present may continue to do business
until adjournment, notwithstanding the withdrawal of enough shareholders to
leave less than a quorum, if any action taken (other than adjournment) is
approved by at least a majority of the shares required to constitute a quorum.

        2.7 ADJOURNED MEETING; NOTICE

        Any shareholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of the majority of the
shares represented at that meeting, either in person or by proxy. In the absence
of a quorum, no other business may be transacted at that meeting except as
provided in Section 2.6 of these bylaws.


                                      -3-


<PAGE>   8
        When any meeting of shareholders, either annual or special, is adjourned
to another time or place, notice need not be given of the adjourned meeting if
the time and place are announced at the meeting at which the adjournment is
taken. However, if a new record date for the adjourned meeting is fixed or if
the adjournment is for more than forty-five (45) days from the date set for the
original meeting, then notice of the adjourned meeting shall be given. Notice of
any such adjourned meeting shall be given to each shareholder of record entitled
to vote at the adjourned meeting in accordance with the provisions of Sections
2.4 and 2.5 of these bylaws. At any adjourned meeting the corporation may
transact any business which might have been transacted at the original meeting.

        2.8 VOTING

        The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of Section 2.11 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

        The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

        Except as provided in the last paragraph of this Section 2.8, or as may
be otherwise provided in the articles of incorporation, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to a
vote of the shareholders. Any shareholder entitled to vote on any matter may
vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or, except when the matter is the election of directors, may
vote them against the proposal; but, if the shareholder fails to specify the
number of shares which the shareholder is voting affirmatively, it will be
conclusively presumed that the shareholder's approving vote is with respect to
all shares which the shareholder is entitled to vote.

        If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation.

        At a shareholders' meeting at which directors are to be elected, a
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such shareholder normally
is entitled to cast) if the candidates' names have been placed in nomination
prior to commencement of the voting and the shareholder has given notice prior
to commencement of the voting of the shareholder's intention to cumulate votes.
If any shareholder has given such a notice, then every shareholder entitled to
vote may cumulate votes for candidates in nomination either (i) by giving one
candidate a number of votes equal to the


                                      -4-


<PAGE>   9
number of directors to be elected multiplied by the number of votes to which
that shareholder's shares are normally entitled or (ii) by distributing the
shareholder's votes on the same principle among any or all of the candidates, as
the shareholder thinks fit. The candidates receiving the highest number of
affirmative votes, up to the number of directors to be elected, shall be
elected; votes against any candidate and votes withheld shall have no legal
effect.

        2.9 VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

        The transactions of any meeting of shareholders, either annual or
special, however called and noticed, and wherever held, shall be as valid as
though they had been taken at a meeting duly held after regular call and notice,
if a quorum be present either in person or by proxy, and if, either before or
after the meeting, each person entitled to vote, who was not present in person
or by proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof. The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of shareholders, except that if action is taken
or proposed to be taken for approval of any of those matters specified in the
second paragraph of Section 2.4 of these bylaws, the waiver of notice or consent
or approval shall state the general nature of the proposal. All such waivers,
consents, and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

        Attendance by a person at a meeting shall also constitute a waiver of
notice of and presence at that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the meeting
is not lawfully called or convened. Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

        2.10 SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any action which may be taken at any annual or special meeting of
shareholders may be taken without a meeting and without prior notice, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take that action at a meeting at which all
shares entitled to vote on that action were present and voted.

        In the case of election of directors, such a consent shall be effective
only if signed by the holders of all outstanding shares entitled to vote for the
election of directors. However, a director may be elected at any time to fill
any vacancy on the board of directors, provided that it was not created by
removal of a director and that it has not been filled by the directors, by the
written


                                      -5-


<PAGE>   10
consent of the holders of a majority of the outstanding shares entitled to vote
for the election of directors.

        All such consents shall be maintained in the corporate records. Any
shareholder giving a written consent, or the shareholder's proxy holders, or a
transferee of the shares, or a personal representative of the shareholder, or
their respective proxy holders, may revoke the consent by a writing received by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

        If the consents of all shareholders entitled to vote have not been
solicited in writing and if the unanimous written consent of all such
shareholders has not been received, then the secretary shall give prompt notice
of the corporate action approved by the shareholders without a meeting. Such
notice shall be given to those shareholders entitled to vote who have not
consented in writing and shall be given in the manner specified in Section 2.5
of these bylaws. In the case of approval of (i) a contract or transaction in
which a director has a direct or indirect financial interest, pursuant to
Section 310 of the Code, (ii) indemnification of a corporate "agent," pursuant
to Section 317 of the Code, (iii) a reorganization of the corporation, pursuant
to Section 1201 of the Code, and (iv) a distribution in dissolution other than
in accordance with the rights of outstanding preferred shares, pursuant to
Section 2007 of the Code, the notice shall be given at least ten (10) days
before the consummation of any action authorized by that approval.

        2.11 RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING CONSENTS

        For purposes of determining the shareholders entitled to notice of any
meeting or to vote thereat or entitled to give consent to corporate action
without a meeting, the board of directors may fix, in advance, a record date,
which shall not be more than sixty (60) days nor less than ten (10) days before
the date of any such meeting nor more than sixty (60) days before any such
action without a meeting, and in such event only shareholders of record on the
date so fixed are entitled to notice and to vote or to give consents, as the
case may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date, except as otherwise provided in the Code.

        If the board of directors does not so fix a record date:

               (a) the record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held; and

               (b) the record date for determining shareholders entitled to give
consent to corporate action in writing without a meeting, (i) when no prior
action by the


                                      -6-


<PAGE>   11
board has been taken, shall be the day on which the first written consent is
given, or (ii) when prior action by the board has been taken, shall be at the
close of business on the day on which the board adopts the resolution relating
to that action, or the sixtieth (60th) day before the date of such other action,
whichever is later.

        The record date for any other purpose shall be as provided in Article
VIII of these bylaws.

        2.12 PROXIES

        Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation. A proxy shall be deemed signed if the shareholder's name is
placed on the proxy (whether by manual signature, typewriting, telegraphic
transmission or otherwise) by the shareholder or the shareholder's
attorney-in-fact. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) the person who
executed the proxy revokes it prior to the time of voting by delivering a
writing to the corporation stating that the proxy is revoked or by executing a
subsequent proxy and presenting it to the meeting or by voting in person at the
meeting, or (ii) written notice of the death or incapacity of the maker of that
proxy is received by the corporation before the vote pursuant to that proxy is
counted; provided, however, that no proxy shall be valid after the expiration of
eleven (11) months from the date of the proxy, unless otherwise provided in the
proxy. The dates contained on the forms of proxy presumptively determine the
order of execution, regardless of the postmark dates on the envelopes in which
they are mailed. The revocability of a proxy that states on its face that it is
irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of
the Code.

        2.13 INSPECTORS OF ELECTION

        Before any meeting of shareholders, the board of directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no inspector of election is so appointed, then the chairman of the meeting
may, and on the request of any shareholder or a shareholder's proxy shall,
appoint an inspector or inspectors of election to act at the meeting. The number
of inspectors shall be either one (l) or three (3). If inspectors are appointed
at a meeting pursuant to the request of one (l) or more shareholders or proxies,
then the holders of a majority of shares or their proxies present at the meeting
shall determine whether one (l) or three (3) inspectors are to be appointed. If
any person appointed as inspector fails to appear or fails or refuses to act,
then the chairman of the meeting may, and upon the request of any shareholder or
a shareholder's proxy shall, appoint a person to fill that vacancy.

        Such inspectors shall:

               (a) determine the number of shares outstanding and the voting
power of each, the number of shares represented at the meeting, the existence of
a quorum, and the authenticity, validity, and effect of proxies;


                                      -7-


<PAGE>   12
               (b) receive votes, ballots or consents;

               (c) hear and determine all challenges and questions in any way
arising in connection with the right to vote;

               (d) count and tabulate all votes or consents;

               (e) determine when the polls shall close;

               (f) determine the result; and

               (g) do any other acts that may be proper to conduct the election
or vote with fairness to all shareholders.


                                   ARTICLE III

                                    DIRECTORS

        3.1 POWERS

        Subject to the provisions of the Code and any limitations in the
articles of incorporation and these bylaws relating to actions required to be
approved by the shareholders or by the outstanding shares, the business and
affairs of the corporation shall be managed and all corporate powers shall be
exercised by or under the direction of the board of directors.

        3.2 NUMBER OF DIRECTORS

        The authorized number of directors shall be seven (7). The authorized
number may be changed by a duly adopted amendment to the articles of
incorporation or by an amendment to this bylaw adopted by the vote or written
consent of holders of a majority of the outstanding shares entitled to vote;
provided, however, that an amendment reducing the fixed number or the minimum
number of directors to a number less than five (5) cannot be adopted if the
votes cast against its adoption at a meeting, or the shares not consenting in
the case of an action by written consent, are equal to more than sixteen and
two-thirds percent (16-2/3%) of the outstanding shares entitled to vote thereon.
No reduction of the authorized number of directors shall have the effect of
removing any director before that director's term of office expires.

        3.3 ELECTION AND TERM OF OFFICE OF DIRECTORS

        Directors shall be elected at each annual meeting of shareholders to
hold office until the next annual meeting. Each director, including a director

        3.4 RESIGNATION AND VACANCIES

        Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may elect a successor to take office when the resignation
becomes effective.

        Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote or
written consent of the shareholders or by court order may be filled only by the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present (which shares voting affirmatively
also constitute a majority of the required quorum), or by the unanimous written
consent of all shares entitled to vote thereon. Each director so elected shall
hold office until the next annual meeting of the shareholders and until a
successor has been elected and qualified.

        A vacancy or vacancies in the board of directors shall be deemed to
exist (i) in the event of the death, resignation or removal of any director,
(ii) if the board of directors by resolution declares vacant the office of a
director who has been declared of unsound mind by an order of court or convicted
of a felony, (iii) if the authorized number of directors is increased, or (iv)
if the shareholders fail, at any meeting of shareholders at which any director
or directors are elected, to elect the number of directors to be elected at that
meeting.

        The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election
other than to fill a vacancy created by removal, if by written consent, shall
require the consent of the holders of a majority of the outstanding shares
entitled to vote thereon.

        3.5 PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular meetings of the board of directors may be held at any place
within or outside the State of California that has been designated from time to
time by resolution of the board. In the absence of such a designation, regular
meetings shall be held at the principal executive office of the corporation.
Special meetings of the board may be held at any place within or outside the
State of California that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice, at the principal executive
office of the corporation.

        Any meeting, regular or special, may be held by conference telephone or
similar communication equipment, so long as all directors participating in the
meeting can hear one another; and all such directors shall be deemed to be
present in person at the meeting.

time of the holding of the meeting. If the notice is delivered personally or by
telephone or telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

        3.8 QUORUM

        A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these bylaws. Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of
Section 310 of the Code (as to approval of contracts or transactions in which a
director has a direct or indirect material financial interest), Section 311 of
the Code (as to appointment of committees), Section 317(e) of the Code (as to
indemnification of directors), the articles of incorporation, and other
applicable law.

        A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

        3.9 WAIVER OF NOTICE

        Notice of a meeting need not be given to any director (i) who signs a

        A majority of the directors present, whether or not constituting a
quorum, may adjourn any meeting to another time and place.

        3.11 NOTICE OF ADJOURNMENT

        Notice of the time and place of holding an adjourned meeting need not be
given unless the meeting is adjourned for more than twenty-four (24) hours. If

the directors who were not present at the time of the adjournment.

        3.12 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any action required or permitted to be taken by the board of directors
may be taken without a meeting, provided that all members of the board
individually or collectively consent in writing to that action. Such action by
written consent shall have the same force and effect as a unanimous vote of the
board of directors. Such written consent and any counterparts thereof shall be
filed with the minutes of the proceedings of the board.

        Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the board of directors. This Section 3.13 shall not

capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

        The corporation may, upon the approval of the board of directors alone,

amounts actually and reasonably incurred in connection with any proceeding (as
defined in Section 317(a) of the Code), arising by reason of the fact that such

"director" or "officer" of the corporation includes any person (i) who is or was
a director or officer of the corporation, (ii) who is or was serving at the
request of the corporation as a director or officer of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was a
director or officer of a corporation which was a predecessor corporation of the

permitted by the Code, to indemnify each of its employees and agents (other than
directors and officers) against expenses (as defined in Section 317(a) of the
Code), judgments, fines, settlements, and other amounts actually and reasonably
incurred in connection with any proceeding (as defined in Section 317(a) of the
Code), arising by reason of the fact that such person is or was an agent of the

corporation (other than a director or officer) includes any person (i) who is or
was an employee or agent of the corporation, (ii) who is or was serving at the
request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the

corporation.

        6.3 PAYMENT OF EXPENSES IN ADVANCE

        Expenses incurred in defending any civil or criminal action or
proceeding for which indemnification is required pursuant to Section 6.1 or for
which indemnification is permitted pursuant to Section 6.2 following
authorization thereof by the Board of Directors shall be paid by the corporation
in advance of the final disposition of such action or proceeding upon receipt of
an undertaking by or on behalf of the indemnified party to repay such amount if
it shall ultimately be determined that the indemnified party is not entitled to
be indemnified as authorized in this Article VI.

<PAGE>   21
        6.4 INDEMNITY NOT EXCLUSIVE

        The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the articles of
incorporation.

        6.5 INSURANCE INDEMNIFICATION

        The corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of

or not the corporation would have the power to indemnify him against such
liability under the provisions of this Article VI.

        6.6 CONFLICTS

        No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

               (1) That it would be inconsistent with a provision of the
articles of incorporation, these bylaws, a resolution of the shareholders or an
agreement in effect at the time of the accrual of the alleged cause of the
action asserted in the proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

               (2) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

        If no annual report for the fiscal year has been sent to shareholders,
then the corporation shall, upon the written request of any shareholder made
more than one hundred twenty (120) days after the close of such fiscal year,
deliver or mail to the person making the request, within thirty (30) days
thereafter, a copy of a balance sheet as of the end of such fiscal year and an
income statement and statement of changes in financial position for such fiscal
year.

        If a shareholder or shareholders holding at least five percent (5%) of
the outstanding shares of any class of stock of the corporation makes a written
request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and for a


                                      -19-


<PAGE>   24
balance sheet of the corporation as of the end of that period, then the chief
financial officer shall cause that statement to be prepared, if not already
prepared, and shall deliver personally or mail that statement or statements to
the person making the request within thirty (30) days after the receipt of the
request. If the corporation has not sent to the shareholders its annual report
for the last fiscal year, the statements referred to in the first paragraph of
this Section 7.6 shall likewise be delivered or mailed to the shareholder or
shareholders within thirty (30) days after the request.

        The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or by the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

        7.7 REPRESENTATION OF SHARES OF OTHER CORPORATIONS

        The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or
any other person authorized by the board of directors or the president or a vice
president, is authorized to vote, represent, and exercise on behalf of this
corporation all rights incident to any and all shares of any other corporation
or corporations standing in the name of this corporation. The authority herein
granted may be exercised either by such person directly or by any other person
authorized to do so by proxy or power of attorney duly executed by such person
having the authority.


                                  ARTICLE VIII

                                 GENERAL MATTERS

        8.1 RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

        For purposes of determining the shareholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action (other than action by shareholders by written consent without a meeting),
the board of directors may fix, in advance, a record date, which shall not be
more than sixty (60) days before any such action. In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the Code.

        If the board of directors does not so fix a record date, then the record
date for determining shareholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution or the
sixtieth (60th) day before the date of that action, whichever is later.


                                      -20-


<PAGE>   25
        8.2 CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

        8.3 CORPORATE CONTRACTS AND INSTRUMENTS; HOW EXECUTED

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

        8.4 CERTIFICATES FOR SHARES

        A certificate or certificates for shares of the corporation shall be
issued to each shareholder when any of such shares are fully paid. The board of
directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid. All certificates
shall be signed in the name of the corporation by the chairman of the board or
the vice chairman of the board or the president or a vice president and by the
chief financial officer or an assistant treasurer or the secretary or an
assistant secretary, certifying the number of shares and the class or series of
shares owned by the shareholder. Any or all of the signatures on the certificate
may be facsimile.

        In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed on a certificate ceases to be that officer,
transfer agent or registrar before that certificate is issued, it may be issued
by the corporation with the same effect as if that person were an officer,
transfer agent or registrar at the date of issue.

        8.5 LOST CERTIFICATES

        Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or


                                      -21-


<PAGE>   26
liability, on account of the alleged loss, theft or destruction of the
certificate or the issuance of the replacement certificate.

        8.6 CONSTRUCTION; DEFINITIONS

        Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Code shall govern the construction of these
bylaws. Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person" includes both a corporation and a natural person.


                                   ARTICLE IX

                                   AMENDMENTS

        9.1 AMENDMENT BY SHAREHOLDERS

        New bylaws may be adopted or these bylaws may be amended or repealed by
the vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that if the articles of incorporation of
the corporation set forth the number of authorized directors of the corporation,
then the authorized number of directors may be changed only by an amendment of
the articles of incorporation.

        9.2 AMENDMENT BY DIRECTORS

        Subject to the rights of the shareholders as provided in Section 9.1 of
these bylaws, bylaws, other than a bylaw or an amendment of a bylaw changing the
authorized number of directors (except to fix the authorized number of directors
pursuant to a bylaw providing for a variable number of directors), may be
adopted, amended or repealed by the board of directors.

                            ARTICLES OF INCORPORATION

                                NETRO CORPORATION


      The undersigned, Gideon Ben-Efraim and Tae Hea Nahm, hereby certify that:

      1. They are the duly elected and acting President and Secretary,
respectively, of Netro Corporation, a California corporation.

      2. The Articles of Incorporation of this Corporation shall be amended and
restated to read in full as follows:

                                   "ARTICLE I

      The name of this corporation is Netro Corporation, (the "Corporation").

                                   ARTICLE II

      The purpose of the Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                   ARTICLE III

      (A) CLASSES OF STOCK. The Corporation is authorized to issue two classes
of stock to be designated, respectively, "Common Stock" and "Preferred Stock."
The total number of shares which the Corporation is authorized to issue is one
hundred five million (105,000,000) shares, each with a par value of $0.001 per
share. One hundred million (100,000,000) shares shall be Common Stock and five
million (5,000,000) shares shall be Preferred Stock.

      (B) The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, within the limitations and
restrictions stated in these Articles of Incorporation, to determine or alter
the rights, preferences, privileges and restrictions granted to or imposed upon
any wholly unissued series of Preferred Stock and the number of shares
constituting any such series and the designation thereof, or any of them; and to
increase or decrease the number of shares of any series subsequent to the
issuance of shares of that series, but not below the number of shares of such
series then outstanding. In case the number of shares of any series shall be so
decreased, the shares constituting such decrease shall resume the status which
they had prior to the adoption of the resolution originally fixing the number of
shares of such series.

<PAGE>   2
                                   ARTICLE IV

      No action shall be taken by the shareholders of the Corporation other than
at an annual or special meeting of the shareholders, upon due notice and in
accordance with the provisions of the Corporation's bylaws.

                                    ARTICLE V

      "Listing Event" as used in these Amended and Restated Articles of
Incorporation shall mean the Corporation becoming a "Listed Corporation" within
the meaning of Section 301.5 of the California Corporations Code.
Effective upon the occurrence of the Listing Event:

      (A) The Board of Directors of the Corporation shall divide the directors
into two classes, as nearly equal in number as reasonably possible, with the
term of office of the first class to expire at the first annual meeting of
shareholders (or any special meeting in lieu thereof) following the effective
date of the Listing Event (the "Effective Date"), and the term of office of the
second class to expire at the second annual meeting of shareholders after the
Effective Date (or any special meeting in lieu thereof). At each annual meeting
of shareholders or special meeting in lieu thereof following such initial
classification, directors elected to succeed those directors whose terms expire
shall be elected for a term of office to expire at the third succeeding annual
meeting of shareholders or special meeting in lieu thereof after their election
and until their successors are duly elected and qualified.

      (B) Subject to the rights of the holders of any series of Preferred Stock
then outstanding, newly created directorships resulting from any increase in the
authorized number of directors or any vacancies in the Board of Directors
resulting from death, resignation, retirement, disqualification, removal from
office or other cause may be filled only by a majority vote of the directors
then in office even though less than a quorum, or by a sole remaining director.
In the event of any increase or decrease in the authorized number of directors,
(i) each director then serving as such shall nevertheless continue as a director
of the class of which he or she is a member until the expiration of his or her
current term or his or her prior death, retirement, removal or resignation and
(ii) the newly created or eliminated directorships resulting from such increase
or decrease shall if reasonably possible be apportioned by the Board of
Directors among the two classes of directors so as to ensure that no one class
has more than one director more than any other class. To the extent reasonably
possible, consistent with the foregoing rule, any newly created directorships
shall be added to those classes whose terms of office are to expire at the
latest dates following such allocation and newly eliminated directorships shall
be subtracted from those classes whose terms of office are to expire at the
earliest dates following such allocation, unless otherwise provided for from
time to time by resolution adopted by a majority of the directors then in
office, although less than a quorum. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board of Directors until the vacancy is filled.
Notwithstanding the foregoing provisions of this Article V, each director shall
serve until his or her successor is duly elected and


                                      -2-
<PAGE>   3
qualified or until his or her death, resignation, or removal. No decrease in
the number of directors constituting the Board of Directors shall shorten the
term of any incumbent director.

      (C) In the election of directors, each holder of shares of any class or
series of capital stock of the Corporation shall be entitled to one vote for
each share held. No shareholder shall be permitted to cumulate votes at any
election of directors.

      (D) Vacancies in the Board of Directors and newly created directorships
resulting from any increase in the authorized number of directors shall be
filled by a vote of the majority of the directors then in office, though less
than a quorum, or by a sole remaining director.

                                   ARTICLE VI

      (A) The liability of the directors of the Corporation for monetary damages
shall be eliminated to the fullest extent permissible under California law.

      (B) The Corporation is authorized to provide indemnification of agents (as
defined in Section 317 of the California Corporations Code) to the fullest
extent permissible under California law.

      (C) Any amendment or repeal or modification of the foregoing provisions of
this Article VI by the shareholders of the Corporation shall not adversely
affect any right or protection of a director of the Corporation existing at the
time of such repeal or modification."

                                      * * *

      3. The foregoing amendment has been approved by the Board of Directors of
this Corporation.

      4. The foregoing amendment was approved by the holders of the requisite
number of shares of this Corporation in accordance with Sections 902 and 903 of
the California General Corporation Law. The total number of outstanding shares
entitled to vote with respect to the foregoing amendment was [__________] shares
of Common Stock. The number of shares voting in favor of the foregoing amendment
equaled or exceeded the vote required. The percentage vote required was a
majority of the outstanding shares of Common Stock. There are no shares of
Preferred Stock outstanding.

        1.1 PRINCIPAL OFFICE

        The board of directors shall fix the location of the principal executive
office of the corporation at any place within or outside the State of

                            MEETINGS OF SHAREHOLDERS

        2.1 PLACE OF MEETINGS

        Meetings of shareholders shall be held at any place within or outside

executive office of the corporation.

        2.2 ANNUAL MEETING

        (a) The annual meeting of shareholders shall be held each year on a date
and at a time designated by the board of directors. In the absence of such
designation, the annual meeting of shareholders shall be held on the third
Tuesday of May in each year at 10:00 a.m. However, if such day falls on a legal
holiday, then the meeting shall be held at the same time and place on the next
succeeding full business day. At the meeting, directors shall be elected, and
any other proper business may be transacted.

        (b) Nominations of persons for election to the board of directors of the

by or at the direction of the board of directors or (iii) by any shareholder of
the corporation who was a shareholder of record at the time of giving of the
notice provided for in this Section 2.2, who is entitled to vote at the meeting
and who has complied with the notice procedures set forth in this Section 2.2.

        (c) For nominations or other business to be properly brought before an
annual meeting by a shareholder pursuant to clause (iii) of paragraph (b) of
this Section 2.2, the shareholder must have given timely notice thereof in
writing to the secretary of the corporation and such business must be a proper
matter for shareholder action under the Corporations Code of California (the
"Code"). To be timely, a shareholder's notice shall be delivered to the
secretary at the principal executive offices of the corporation not less than
twenty (20) days nor more than ninety (90) days prior to the first anniversary
of the preceding year's annual meeting of shareholders; provided, however, that
in the event that the date of the annual meeting is more than thirty (30) days
prior to or more than sixty (60) days after such anniversary date, notice by the
shareholder to be timely must be so delivered not earlier than the ninetieth
(90th) day prior to such annual meeting and not later than the close of business
on the later of the twentieth (20th) day prior to such annual meeting or the
tenth (10th) day following the day on which public announcement of the date of
such meeting is first made. Such shareholder's notice shall set forth (i) as to
each person whom the shareholder proposes to nominate for election or reelection
as a director all information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors, or is otherwise
required, in each case pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (including such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); (ii) as to any other business that the shareholder
proposes to bring before the meeting, a brief description of such business, the
reasons for conducting such business at the meeting and any material interest in
such business of such shareholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (iii) as to the shareholder giving the notice
and the beneficial owner, if any, on whose behalf the nomination or proposal is
made (A) the name and address of such shareholder, as they appear on the
corporation's books, and of such beneficial owner and (B) the class and number
of shares of the corporation which are owned beneficially and of record by such
shareholder and such beneficial owner.

        (d) Only persons nominated in accordance with the procedures set forth
in this Section 2.2 shall be eligible to serve as directors and only such
business shall be conducted at an annual meeting of shareholders as shall have
been brought before the meeting in accordance with the procedures set forth in
this Section 2.2. The chairman of the meeting shall determine whether a
nomination or any business proposed to be transacted by the shareholders has
been properly brought before the meeting and, if any proposed nomination or
business has not been properly brought before the meeting, the chairman shall
declare that such proposed business or nomination shall not be presented for
shareholder action at the meeting.

        (e) For purposes of this Section 2.2, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service.



                                       2
<PAGE>   8

        (f) Nothing in this Section 2.2 shall be deemed to affect any rights of
shareholders to request inclusion of proposals in the corporation's proxy
statement pursuant to Rule 14a-8 under the Exchange Act.

        2.3 SPECIAL MEETING

        (a) A special meeting of the shareholders may be called at any time by
the board of directors, or by the chairman of the board, or by the president, or
by one or more shareholders holding shares in the aggregate entitled to cast not
less than ten percent (10%) of the votes at that meeting.

        (b) If a special meeting is called by any person or persons other than
the board of directors or the president or the chairman of the board, then the
request shall be in writing, specifying the time of such meeting and the general
nature of the business proposed to be transacted, and shall be delivered
personally or sent by registered mail or by telegraphic or other facsimile
transmission to the chairman of the board, the president, any vice president or
the secretary of the corporation. No business may be transacted at such special
meeting otherwise than specified in such notice. The officer receiving the
request shall cause notice to be promptly given to the shareholders entitled to
vote, in accordance with the provisions of Sections 2.4 and 2.5 of these bylaws,
that a meeting will be held at the time requested by the person or persons
calling the meeting, so long as that time is not less than thirty-five (35) nor
more than sixty (60) days after the receipt of the request. If the notice is not
given within twenty (20) days after receipt of the request, then the person or
persons requesting the meeting may give the notice. Nothing contained in this
paragraph of this Section 2.3 shall be construed as limiting, fixing or
affecting the time when a meeting of shareholders called by action of the board
of directors may be held.

        (c) Only such business shall be conducted at a special meeting of
shareholders as shall have been brought before the meeting pursuant to the
notice of meeting given in accordance with the provisions of Section 2.3(b).
Nominations of persons for election to the board of directors may be made at a
special meeting of shareholders at which directors are to be selected pursuant
to such notice of meeting (i) by or at the direction of the board of directors
or (ii) by any shareholder of the corporation who is a shareholder of record at
the time of giving of notice provided for in this Section 2.3(c), who shall be
entitled to vote at the meeting and who complies with the notice procedures set
forth in this Section 2.3(c). Nominations by shareholders of persons for
election to the board of directors may be made at such a special meeting of
shareholders if the shareholder's notice required by Section 2.2(c) shall be
delivered to the secretary at the principal executive offices of the corporation
not earlier than the ninetieth (90th) day prior to such special meeting and not
later than the close of business on the later of the twentieth (20th) day prior
to such special meeting or the tenth (10th) day following the day on which
public announcement is first made of the date of the special meeting and of the
nominees proposed by the board of directors to be selected at such meeting.

        2.4 NOTICE OF SHAREHOLDERS' MEETINGS

        All notices of meetings of shareholders shall be sent or otherwise given
in accordance with Section 2.5 of these bylaws not less than ten (10) (or, if
sent by third-class mail pursuant to Section 2.5 of these bylaws, thirty (30))
nor more than sixty (60) days before the date of the meeting. The notice shall
specify the place, date, and hour of the meeting and (i) in the case of a
special meeting, the general nature of the business to be transacted (no
business other than that specified in the notice may be transacted) or (ii) in
the case of the annual meeting, those matters which the board of directors, at
the time of giving the notice, intends to present for action by the shareholders
(but subject to the provisions of the next paragraph of this Section 2.4 any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

        If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Code, (ii) an amendment of the articles
of incorporation, pursuant to Section 902 of the Code, (iii) a reorganization of
the corporation, pursuant to Section 1201 of the Code, (iv) a voluntary
dissolution of the corporation, pursuant to Section 1900 of the Code, or (v) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, pursuant to Section 2007 of the Code, then the
notice shall also state the general nature of that proposal.

        2.5 ADVANCE NOTICE OF SHAREHOLDER NOMINEES

        Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the board of directors of the corporation
may be made at a meeting of shareholders by or at the direction of the board of
directors or by any shareholder of the corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5. Such nominations, other than those made by or at the
direction of the board of directors, shall be made pursuant to timely notice in
writing to the secretary of the corporation. To be timely, a shareholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the corporation not less than twenty (20) days nor more than ninety
(90) days prior to the meeting; provided, however, that in the event that less
than thirty (30) days' notice or prior public disclosure of the date of the
meeting is given or made to shareholders, notice by the shareholder to be timely
must be so received not later than the close of business on the 10th day
following the day on which such notice of the date of the meeting was mailed or
such public disclosure was made. Such shareholder's notice shall set forth (a)
as to each person whom the shareholder proposes to nominate for election or
re-election as a Director, (i) the name, age, business address and residence
address of such person, (ii) the principal occupation or employment of such
person, (iii) the class and number of shares of the corporation which are
beneficially owned by such person and (iv) any other information relating to
such person that is required to be disclosed in solicitations of proxies for
election of Directors, or is otherwise required, in each case pursuant to
Regulation 14A under the Securities Exchange Act of 1934, as



                                       4
<PAGE>   10
amended (including, without limitation, such person's written consent to being
named in the proxy statement as a nominee and to serving as a director if
elected); and (b) as to the shareholder giving the notice (1) the name and
address, as they appear on the corporation's books, of such shareholder and (2)
the class and number of shares of the corporation which are beneficially owned
by such shareholder. At the request of the board of directors any person
nominated by the board of directors for election as a director shall furnish to
the secretary of the corporation that information required to be set forth in a
shareholder's notice of nomination which pertains to the nominee. No person
shall be eligible for election as a director of the corporation unless nominated
in accordance with the procedures set forth in this Section 2.5. The Chairman of
the meeting shall, if the facts warrant, determine and declare to the meeting
that a nomination was not made in accordance with the procedures prescribed by
the Bylaws, and if he or she should so determine, he or she shall so declare to
the meeting and the defective nomination shall be disregarded.

        2.6 MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

        Written notice of any meeting of shareholders shall be given either (i)
personally or (ii) by first-class mail or (iii) by third-class mail but only if
the corporation has outstanding shares held of record by five hundred (500) or
more persons (determined as provided in Section 605 of the Code) on the record
date for the shareholders' meeting, or (iv) by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the shareholder at the address of that shareholder
appearing on the books of the corporation or given by the shareholder to the
corporation for the purpose of notice. If no such address appears on the
corporation's books or is given, notice shall be deemed to have been given if
sent to that shareholder by mail or telegraphic or other written communication
to the corporation's principal executive office, or if published at least once
in a newspaper of general circulation in the county where that office is
located. Notice shall be deemed to have been given at the time when delivered
personally or deposited in the mail or sent by telegram or other means of
written communication.

        If any notice addressed to a shareholder at the address of that
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at that address, then all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder on written demand of the shareholder at the principal executive
office of the corporation for a period of one (1) year from the date of the
giving of the notice.

        An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

        2.7    QUORUM

        The  presence  in person or by proxy of the holders of a majority of the
shares  entitled to vote thereat  constitutes  a quorum for the  transaction  of
business at all meetings of  shareholders.



                                       5
<PAGE>   11

The shareholders present at a duly called or held meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum.

        2.8 ADJOURNED MEETING; NOTICE

        Any shareholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of the majority of the
shares represented at that meeting, either in person or by proxy. In the absence
of a quorum, no other business may be transacted at that meeting except as
provided in Section 2.6 of these bylaws.

        When any meeting of shareholders, either annual or special, is adjourned
to another time or place, notice need not be given of the adjourned meeting if
the time and place are announced at the meeting at which the adjournment is
taken. However, if a new record date for the adjourned meeting is fixed or if
the adjournment is for more than forty-five (45) days from the date set for the
original meeting, then notice of the adjourned meeting shall be given. Notice of
any such adjourned meeting shall be given to each shareholder of record entitled
to vote at the adjourned meeting in accordance with the provisions of Sections
2.4 and 2.5 of these bylaws. At any adjourned meeting the corporation may
transact any business which might have been transacted at the original meeting.

        2.9 VOTING

        The shareholders entitled to vote at any meeting of shareholders shall
be determined in accordance with the provisions of Section 2.10 of these bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation or in joint
ownership).

        The shareholders' vote may be by voice vote or by ballot; provided,
however, that any election for directors must be by ballot if demanded by any
shareholder at the meeting and before the voting has begun.

        Except as may be otherwise provided in the articles of incorporation,
each outstanding share, regardless of class, shall be entitled to one vote on
each matter submitted to a vote of the shareholders. Any shareholder entitled to
vote on any matter may vote part of the shares in favor of the proposal and
refrain from voting the remaining shares or, except when the matter is the
election of directors, may vote them against the proposal; but, if the
shareholder fails to specify the number of shares which the shareholder is
voting affirmatively, it will be conclusively presumed that the shareholder's
approving vote is with respect to all shares which the shareholder is entitled
to vote.

        If a quorum is present, the affirmative vote of the majority of the
shares represented and voting at a duly held meeting (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or a vote by
classes is required by the Code or by the articles of incorporation.

        2.10 CUMULATIVE VOTING

        Shareholders shall not be entitled to cumulate votes for the election of
directors of this corporation.

        This Article shall become effective only when the corporation becomes,
and only for so long as the corporation remains, a listed corporation within the
meaning of Section 301.5 of the California Corporations Code.

        2.11 SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        No action shall be taken by the shareholders of the corporation other
than at an annual or special meeting of the shareholders, upon due notice and in
accordance with the other provisions of these Bylaws.

        2.12 VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

        The transactions of any meeting of shareholders, either annual or
special, however called and noticed, and wherever held, shall be as valid as
though they had been taken at a meeting duly held after regular call and notice,
if a quorum be present either in person or by proxy, and if, either before or
after the meeting, each person entitled to vote, who was not present in person
or by proxy, signs a written waiver of notice or a consent to the holding of the
meeting or an approval of the minutes thereof. The waiver of notice or consent
or approval need not specify either the business to be transacted or the purpose
of any annual or special meeting of shareholders, except that if action is taken
or proposed to be taken for approval of any of those matters specified in the
second paragraph of Section 2.4 of these bylaws, the waiver of notice or consent
or approval shall state the general nature of the proposal. All such waivers,
consents, and approvals shall be filed with the corporate records or made a part
of the minutes of the meeting.

        Attendance by a person at a meeting shall also constitute a waiver of
notice of and presence at that meeting, except when the person objects at the
beginning of the meeting to the transaction of any business because the meeting
is not lawfully called or convened. Attendance at a meeting is not a waiver of
any right to object to the consideration of matters required by the Code to be
included in the notice of the meeting but not so included, if that objection is
expressly made at the meeting.

        2.13 RECORD DATE FOR SHAREHOLDER NOTICE; VOTING

        For purposes of determining the shareholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not be more than sixty (60) days nor less than ten (10) days
before the date of any such meeting, and in such event only shareholders of
record on the date so fixed are entitled to notice and to vote, notwithstanding
any transfer of any shares on the books of the corporation after the record
date, except as otherwise provided in the Code.



                                       7
<PAGE>   13

        If the board of directors does not so fix a record date the record date
for determining shareholders entitled to notice of or to vote at a meeting of
shareholders shall be at the close of business on the business day next
preceding the day on which notice is given or, if notice is waived, at the close
of business on the business day next preceding the day on which the meeting is
held; and

        The record date for any other purpose shall be as provided in Article
VIII of these bylaws.

        2.14 PROXIES

        Every person entitled to vote for directors, or on any other matter,
shall have the right to do so either in person or by one or more agents
authorized by a written proxy signed by the person and filed with the secretary
of the corporation. A proxy shall be deemed signed if the shareholder's name is
placed on the proxy (whether by manual signature, typewriting, telegraphic
transmission or otherwise) by the shareholder or the shareholder's
attorney-in-fact. A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless (i) the person who
executed the proxy revokes it prior to the time of voting by delivering a
writing to the corporation stating that the proxy is revoked or by executing a
subsequent proxy and presenting it to the meeting or by voting in person at the
meeting, or (ii) written notice of the death or incapacity of the maker of that
proxy is received by the corporation before the vote pursuant to that proxy is
counted; provided, however, that no proxy shall be valid after the expiration of
eleven (11) months from the date of the proxy, unless otherwise provided in the
proxy. The dates contained on the forms of proxy presumptively determine the
order of execution, regardless of the postmark dates on the envelopes in which
they are mailed. The revocability of a proxy that states on its face that it is
irrevocable shall be governed by the provisions of Sections 705(e) and 705(f) of
the Code.

        2.15 INSPECTORS OF ELECTION

        Before any meeting of shareholders, the board of directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no inspector of election is so appointed, then the chairman of the meeting
may, and on the request of any shareholder or a shareholder's proxy shall,
appoint an inspector or inspectors of election to act at the meeting. The number
of inspectors shall be either one (1) or three (3). If inspectors are appointed
at a meeting pursuant to the request of one (1) or more shareholders or proxies,
then the holders of a majority of shares or their proxies present at the meeting
shall determine whether one (1) or three (3) inspectors are to be appointed. If
any person appointed as inspector fails to appear or fails or refuses to act,
then the chairman of the meeting may, and upon the request of any shareholder or
a shareholder's proxy shall, appoint a person to fill that vacancy.

        Such inspectors shall:

                (a) determine the number of shares outstanding and the voting
power of each, the number of shares represented at the meeting, the existence of
a quorum, and the authenticity, validity, and effect of proxies;



                                       8
<PAGE>   14

                (b) receive votes, ballots or consents;

                (c) hear and determine all challenges and questions in any way
arising in connection with the right to vote;

                (d) count and tabulate all votes or consents;

                (e) determine when the polls shall close;

                (f) determine the result; and

                (g) do any other acts that may be proper to conduct the election
or vote with fairness to all shareholders.


                                   ARTICLE III

                                    DIRECTORS

        3.1 POWERS

        Subject to the provisions of the Code and any limitations in the
articles of incorporation and these bylaws relating to actions required to be
approved by the shareholders or by the outstanding shares, the business and
affairs of the corporation shall be managed and all corporate powers shall be
exercised by or under the direction of the board of directors.

        3.2 NUMBER OF DIRECTORS

        The number of directors of the corporation shall be not less than four
(4) nor more than seven (7). The exact number of directors shall be six (6)
until changed, within the limits specified above, by a bylaw amending this
Section 3.2, duly adopted by the board of directors or by the shareholders. The
indefinite number of directors may be changed, or a definite number may be fixed
without provision for an indefinite number, by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw duly adopted by the
vote or written consent of holders of a majority of the outstanding shares
entitled to vote; provided, however, that an amendment reducing the fixed number
or the minimum number of directors to a number less than six (6) cannot be
adopted if the votes cast against its adoption at a meeting, or the shares not
consenting in the case of an action by written consent, are equal to more than
sixteen and two-thirds percent (16-2/3%) of the outstanding shares entitled to
vote thereon. No amendment may change the stated maximum number of authorized
directors to a number greater than two (2) times the stated minimum number of
directors minus one (1).

        No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

        3.3 ELECTION AND TERM OF OFFICE OF DIRECTORS

        Directors shall be elected at each annual meeting of the shareholders to
hold office until the next annual meeting. Each director, including a director
elected to fill a vacancy, shall hold office until the expiration of the term
for which elected and until a successor has been elected and qualified.

        3.4 RESIGNATION AND VACANCIES

        Any director may resign effective on giving written notice to the
chairman of the board, the president, the secretary or the board of directors,
unless the notice specifies a later time for that resignation to become
effective. If the resignation of a director is effective at a future time, the
board of directors may elect a successor to take office when the resignation
becomes effective.

        Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the shareholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum). Each director so elected shall hold office for
a term expiring at the annual meeting of shareholders at which the term of
office of the class to which they have been elected expires, if applicable, and
if no such classes shall have been established, at the next annual meeting of
the shareholders and until a successor has been elected and qualified.

        A vacancy or vacancies in the board of directors shall be deemed to
exist (i) in the event of the death, resignation or removal of any director,
(ii) if the board of directors by resolution declares vacant the office of a
director who has been declared of unsound mind by an order of court or convicted
of a felony, (iii) if the authorized number of directors is increased, or (iv)
if the shareholders fail, at any meeting of shareholders at which any director
or directors are elected, to elect the number of directors to be elected at that
meeting.

        The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election
other than to fill a vacancy created by



                                       10
<PAGE>   16

removal shall require the consent of the holders of a majority of the
outstanding shares entitled to vote thereon.

        3.5 PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular meetings of the board of directors may be held at any place
within or outside the State of California that has been designated from time to

Special meetings of the board may be held at any place within or outside the
State of California that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice, at the principal executive
office of the corporation.

personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. If the notice is mailed, it
shall be deposited in the United States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally or by
telephone or telegram, it shall be delivered personally or by telephone or to
the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose or the place of the
meeting, if the meeting is to be held at the principal executive office of the
corporation.

        3.8 QUORUM

        A majority of the authorized number of directors shall constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these bylaws. Every act or decision done or made by a majority of the
directors present at a duly held meeting at which a quorum is present shall be
regarded as the act of the board of directors, subject to the provisions of
Section 310 of the Code (as to approval of contracts or transactions in which a
director has a



                                       11

transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

        3.9 WAIVER OF NOTICE

        Notice of a meeting need not be given to any director (i) who signs a
waiver of notice or a consent to holding the meeting or an approval of the
minutes thereof, whether before or after the meeting, or (ii) who attends the
meeting without protesting, prior thereto or at its commencement, the lack of
notice to such director. All such waivers, consents, and approvals shall be
filed with the corporate records or made part of the minutes of the meeting. A
waiver of notice need not specify the purpose of any regular or special meeting
of the board of directors.

        3.10 ADJOURNMENT

        A majority of the directors present, whether or not constituting a
quorum, may adjourn any meeting to another time and place.

        3.11 NOTICE OF ADJOURNMENT

        Notice of the time and place of holding an adjourned meeting need not be
given unless the meeting is adjourned for more than twenty-four (24) hours. If
the meeting is adjourned for more than twenty-four (24) hours, then notice of
the time and place of the adjourned meeting shall be given before the adjourned
meeting takes place, in the manner specified in Section 3.7 of these bylaws, to
the directors who were not present at the time of the adjournment.

        3.12 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any action required or permitted to be taken by the board of directors
may be taken without a meeting, provided that all members of the board
individually or collectively consent in writing to that action. Such action by
written consent shall have the same force and effect as a unanimous vote of the
board of directors. Such written consent and any counterparts thereof shall be
filed with the minutes of the proceedings of the board.

        3.13 FEES AND COMPENSATION OF DIRECTORS

        Directors and members of committees may receive such compensation, if
any, for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the board of directors. This Section 3.13 shall not

capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

make loans of money or property to, or guarantee the obligations of, any officer
of the corporation or its parent or subsidiary, whether or not a director, or
adopt an employee benefit plan or plans authorizing such loans or guaranties

        The board of directors may, by resolution adopted by a majority of the

consisting of two or more directors, to serve at the pleasure of the board. The
board may designate one (1) or more directors as alternate members of any
committee, who may replace any absent member at any meeting of the committee.
The appointment of members or alternate members of a committee requires the vote
of a majority of the authorized number of directors. Any committee, to the

or by resolution of the committee, that special meetings of committees may also
be called by resolution of the board of directors, and that notice of special
meetings of committees shall also be given to all alternate members, who shall

        6.4 INDEMNITY NOT EXCLUSIVE

        The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any bylaw, agreement,



                                       17

vote of shareholders or disinterested directors or otherwise, both as to action
in an official capacity and as to action in another capacity while holding such
office, to the extent that such additional rights to indemnification are
authorized in the articles of incorporation.

        6.5 INSURANCE INDEMNIFICATION

        The corporation shall have the power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
the corporation against any liability asserted against or incurred by such
person in such capacity or arising out of such person's status as such, whether
or not the corporation would have the power to indemnify him against such
liability under the provisions of this Article VI.

        6.6 CONFLICTS

        No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

        (1) That it would be inconsistent with a provision of the articles of
incorporation, these bylaws, a resolution of the shareholders or an agreement in
effect at the time of the accrual of the alleged cause of the action asserted in
the proceeding in which the expenses were incurred or other amounts were paid,
which prohibits or otherwise limits indemnification; or

        (2) That it would be inconsistent with any condition expressly imposed
by a court in approving a settlement.


                                   ARTICLE VII

                               RECORDS AND REPORTS

        7.1 MAINTENANCE AND INSPECTION OF SHARE REGISTER

        The corporation shall keep either at its principal executive office or
at the office of its transfer agent or registrar (if either be appointed), as
determined by resolution of the board of directors, a record of its shareholders
listing the names and addresses of all shareholders and the number and class of
shares held by each shareholder.

        A shareholder or shareholders of the corporation who holds at least five
percent (5%) in the aggregate of the outstanding voting shares of the
corporation or who holds at least one percent (1%) of such voting shares and has
filed a Schedule 14B with the Securities and Exchange Commission relating to the
election of directors, may (i) inspect and copy the records of shareholders'
names, addresses, and shareholdings during usual business hours on five (5)
days' prior written demand on the corporation, (ii) obtain from the transfer
agent of the corporation, on written demand and on the tender of such transfer
agent's usual charges for such list, a list of the names and addresses of the
shareholders who are entitled to vote for the election of directors, and their
shareholdings, as of the most recent record date for which that list has been



                                       18
<PAGE>   24

compiled or as of a date specified by the shareholder after the date of demand.
Such list shall be made available to any such shareholder by the transfer agent
on or before the later of five (5) days after the demand is received or five (5)
days after the date specified in the demand as the date as of which the list is
to be compiled.

        The record of shareholders shall also be open to inspection on the
written demand of any shareholder or holder of a voting trust certificate, at
any time during usual business hours, for a purpose reasonably related to the
holder's interests as a shareholder or as the holder of a voting trust
certificate.

        Any inspection and copying under this Section 7.1 may be made in person
or by an agent or attorney of the shareholder or holder of a voting trust
certificate making the demand.

        7.2 MAINTENANCE AND INSPECTION OF BYLAWS

        The corporation shall keep at its principal executive office or, if its
principal executive office is not in the State of California, at its principal
business office in California the original or a copy of these bylaws as amended
to date, which bylaws shall be open to inspection by the shareholders at all
reasonable times during office hours. If the principal executive office of the
corporation is outside the State of California and the corporation has no
principal business office in such state, then the secretary shall, upon the
written request of any shareholder, furnish to that shareholder a copy of these
bylaws as amended to date.

        7.3 MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS

        The accounting books and records and the minutes of proceedings of the
shareholders, of the board of directors, and of any committee or committees of
the board of directors shall be kept at such place or places as are designated
by the board of directors or, in absence of such designation, at the principal
executive office of the corporation. The minutes shall be kept in written form,
and the accounting books and records shall be kept either in written form or in
any other form capable of being converted into written form.

        The minutes and accounting books and records shall be open to inspection
upon the written demand of any shareholder or holder of a voting trust
certificate, at any reasonable time during usual business hours, for a purpose
reasonably related to the holder's interests as a shareholder or as the holder
of a voting trust certificate. The inspection may be made in person or by an
agent or attorney and shall include the right to copy and make extracts. Such
rights of inspection shall extend to the records of each subsidiary corporation
of the corporation.

        7.4 INSPECTION BY DIRECTORS

        Every director shall have the absolute right at any reasonable time to
inspect all books, records, and documents of every kind as well as the physical
properties of the corporation and each of its subsidiary corporations. Such
inspection by a director may be made in person or by an agent or attorney. The
right of inspection includes the right to copy and make extracts of documents.

        7.5 ANNUAL REPORT TO SHAREHOLDERS; WAIVER

        The board of directors shall cause an annual report to be sent to the
shareholders not later than one hundred twenty (120) days after the close of the
fiscal year adopted by the corporation. Such report shall be sent at least
fifteen (15) days (or, if sent by third-class mail, thirty-five (35) days)
before the annual meeting of shareholders to be held during the next fiscal year
and in the manner specified in Section 2.5 of these bylaws for giving notice to
shareholders of the corporation.

        The annual report shall contain (i) a balance sheet as of the end of the
fiscal year, (ii) an income statement, (iii) a statement of changes in financial
position for the fiscal year, and (iv) any report of independent accountants or,
if there is no such report, the certificate of an authorized officer of the
corporation that the statements were prepared without audit from the books and
records of the corporation.

        The foregoing requirement of an annual report shall be waived so long as
the shares of the corporation are held by fewer than one hundred (100) holders
of record.

        7.6 FINANCIAL STATEMENTS

        If no annual report for the fiscal year has been sent to shareholders,
then the corporation shall, upon the written request of any shareholder made
more than one hundred twenty (120) days after the close of such fiscal year,
deliver or mail to the person making the request, within thirty (30) days
thereafter, a copy of a balance sheet as of the end of such fiscal year and an
income statement and statement of changes in financial position for such fiscal
year.

        If a shareholder or shareholders holding at least five percent (5%) of
the outstanding shares of any class of stock of the corporation makes a written
request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and for a
balance sheet of the corporation as of the end of that period, then the chief
financial officer shall cause that statement to be prepared, if not already
prepared, and shall deliver personally or mail that statement or statements to
the person making the request within thirty (30) days after the receipt of the
request. If the corporation has not sent to the shareholders its annual report
for the last fiscal year, the statements referred to in the first paragraph of
this Section 7.6 shall likewise be delivered or mailed to the shareholder or
shareholders within thirty (30) days after the request.

        The quarterly income statements and balance sheets referred to in this
section shall be accompanied by the report, if any, of any independent
accountants engaged by the corporation or by the certificate of an authorized
officer of the corporation that the financial statements were prepared without
audit from the books and records of the corporation.

        7.7 REPRESENTATION OF SHARES OF OTHER CORPORATIONS

        The chairman of the board, the president, any vice president, the chief
financial officer, the secretary or assistant secretary of this corporation, or
any other person authorized by the



                                       20
<PAGE>   26

board of directors or the president or a vice president, is authorized to vote,
represent, and exercise on behalf of this corporation all rights incident to any
and all shares of any other corporation or corporations standing in the name of
this corporation. The authority herein granted may be exercised either by such
person directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.


                                  ARTICLE VIII

                                 GENERAL MATTERS

        8.1 RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

        For purposes of determining the shareholders entitled to receive payment
of any dividend or other distribution or allotment of any rights or the
shareholders entitled to exercise any rights in respect of any other lawful
action (other than action by shareholders by written consent without a meeting),
the board of directors may fix, in advance, a record date, which shall not be
more than sixty (60) days before any such action. In that case, only
shareholders of record at the close of business on the date so fixed are
entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided in the Code.

        If the board of directors does not so fix a record date, then the record
date for determining shareholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution or the
sixtieth (60th) day before the date of that action, whichever is later.

        8.2 CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

        From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

        8.3 CORPORATE CONTRACTS AND INSTRUMENTS; HOW EXECUTED

        The board of directors, except as otherwise provided in these bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
corporation; such authority may be general or confined to specific instances.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
authority to bind the corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.



                                       21
<PAGE>   27

        8.4 CERTIFICATES FOR SHARES

        A certificate or certificates for shares of the corporation shall be
issued to each shareholder when any of such shares are fully paid. The board of
directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid. All certificates
shall be signed in the name of the corporation by the chairman of the board or
the vice chairman of the board or the president or a vice president and by the
chief financial officer or an assistant treasurer or the secretary or an
assistant secretary, certifying the number of shares and the class or series of
shares owned by the shareholder. Any or all of the signatures on the certificate
may be facsimile.

        In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed on a certificate ceases to be that officer,
transfer agent or registrar before that certificate is issued, it may be issued
by the corporation with the same effect as if that person were an officer,
transfer agent or registrar at the date of issue.

        8.5 LOST CERTIFICATES

        Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and canceled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

        8.6 CONSTRUCTION; DEFINITIONS

        Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Code shall govern the construction of these
bylaws. Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person" includes both a corporation and a natural person.


                                   ARTICLE IX

                                   AMENDMENTS

        9.1 AMENDMENT BY SHAREHOLDERS

        New bylaws may be adopted or these bylaws may be amended or repealed by
the vote of holders of a majority of the outstanding shares entitled to vote;
provided, however, that if the articles of incorporation of the corporation set
forth the number of authorized directors of the



                                       22
<PAGE>   28

corporation, then the authorized number of directors may be changed only by an
amendment of the articles of incorporation.

        9.2 AMENDMENT BY DIRECTORS

        Subject to the rights of the shareholders as provided in Section 9.1 of
these bylaws, bylaws, other than a bylaw or an amendment of a bylaw changing the
authorized number of directors (except to fix the authorized number of directors
pursuant to a bylaw providing for a variable number of directors), may be
adopted, amended or repealed by the board of directors.

        The undersigned hereby certifies that he is the duly elected, qualified,
and acting Secretary of Netro Corporation (the "Company"), and that the
foregoing Bylaws, comprising twenty-three (23) pages, were adopted by the board
of directors of the Company as the Amended and Restated Bylaws of the

                            INDEMNIFICATION AGREEMENT

        This Indemnification Agreement ("Agreement") is made as of
_____________, by and between Netro Corporation, a California corporation (the
"Company"), and _________ ("Indemnitee").

        WHEREAS, the Company and Indemnitee recognize the difficulty in
obtaining directors' and officers' liability insurance, the cost of such
insurance and the limited scope of coverage of such insurance;

        WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting officers and directors
to expensive litigation risks at the same time as the availability and coverage
of liability insurance has been severely limited;

        WHEREAS, Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other officers and
directors of the Company may not be willing to continue to serve as officers and
directors without additional protection; and

        WHEREAS, the Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve as officers and
directors of the Company and to indemnify its officers and directors so as to
provide them with the maximum protection permitted by law.

        NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

        1.      Indemnification.

                (a) Third Party Proceedings. The Company shall indemnify
Indemnitee if Indemnitee is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the Company) by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action, suit or proceeding if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe Indemnitee's
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that Indemnitee did
not act in good faith and in a manner which Indemnitee reasonably believed to be
in or not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that Indemnitee's



<PAGE>   2

conduct was unlawful.

                (b) Proceedings By or in the Right of the Company. The Company
shall indemnify Indemnitee if Indemnitee was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in
the right of the Company or any subsidiary of the Company to procure a judgment
in its favor by reason of the fact that Indemnitee is or was a director,
officer, employee or agent of the Company, or any subsidiary of the Company, by
reason of any action or inaction on the part of Indemnitee while an officer or
director or by reason of the fact that Indemnitee is or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) and, to the fullest extent permitted by
law, amounts paid in settlement, in each case to the extent actually and
reasonably incurred by Indemnitee in connection with the defense or settlement
of such action or suit if Indemnitee acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of
the Company and its shareholders, except that no indemnification shall be made
in respect of any claim, issue or matter as to which Indemnitee shall have been
adjudged to be liable to the Company in the performance of Indemnitee's duty to
the Company and its shareholders unless and only to the extent that the court in
which such action or suit is or was pending shall determine upon application
that, in view of all the circumstances of the case, Indemnitee is fairly and
reasonably entitled to indemnity for expenses and then only to the extent that
the court shall determine.

                (c) Mandatory Payment of Expenses. To the extent that Indemnitee
has been successful on the merits or otherwise in defense of any action, suit or
proceeding referred to in Subsections (a) and (b) of this Section 1 or the
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
Indemnitee in connection therewith.

        2.      Expenses; Indemnification Procedure.

                (a) Advancement of Expenses. The Company may advance all
expenses incurred by Indemnitee in connection with the investigation, defense,
settlement or appeal of any civil or criminal action, suit or proceeding
referenced in Section l(a) or (b) hereof (but not amounts actually paid in
settlement of any such action, suit or proceeding). Indemnitee hereby undertakes
to repay such amounts advanced only if, and to the extent that, it shall
ultimately be determined that Indemnitee is not entitled to be indemnified by
the Company as authorized hereby. Any advances made hereunder shall be paid by
the Company to Indemnitee within twenty (20) days following delivery of a
written request therefor by Indemnitee to the Company.

                (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to his or her right to be indemnified under this Agreement,
give the Company notice in writing as soon as practicable of any claim made
against Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the Chief Executive
Officer of the Company at the address shown on the signature page of this
Agreement (or such other address as the Company shall designate in writing to
Indemnitee). Notice shall be deemed received three business days after the date
postmarked if sent by domestic certified or



                                      -2-
<PAGE>   3

registered mail, properly addressed, otherwise notice shall be deemed received
when such notice shall actually be received by the Company. In addition,
Indemnitee shall give the Company such information and cooperation as it may
reasonably require and as shall be within Indemnitee's power.

                (c) Procedure. Any indemnification and advances provided for in
Section 1 shall be made no later than forty-five (45) days after receipt of the
written request of Indemnitee. If a claim under this Agreement, under any
statute, or under any provision of the Company's Articles of Incorporation or
Bylaws providing for indemnification, is not paid in full by the Company within
forty-five (45) days after a written request for payment thereof has first been
received by the Company, Indemnitee may, but need not, at any time thereafter
bring an action against the Company to recover the unpaid amount of the claim
and, subject to Section 13 of this Agreement, Indemnitee shall also be entitled
to be paid for the expenses (including attorneys' fees) of bringing such action.
It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in connection with any action, suit or
proceeding in advance of its final disposition) that Indemnitee has not met the
standards of conduct which make it permissible under applicable law for the
Company to indemnify Indemnitee for the amount claimed. Indemnitee shall be
entitled to receive interim payments of expenses pursuant to Subsection 2(a)
unless and until such defense may be finally adjudicated by court order or
judgment from which no further right of appeal exists. It is the parties'
intention that if the Company contests Indemnitee's right to indemnification,
the question of Indemnitee's right to indemnification shall be for the court to
decide, and neither the failure of the Company (including its Board of
Directors, any committee or subgroup of the Board of Directors, independent
legal counsel, or its shareholders) to have made a determination that
indemnification of Indemnitee is proper in the circumstances because Indemnitee
has met the applicable standard of conduct required by applicable law, nor an
actual determination by the Company (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its shareholders) that Indemnitee has not met such applicable standard of
conduct, shall create a presumption that Indemnitee has or has not met the
applicable standard of conduct.

                (d) Notice to Insurers. If, at the time of the receipt of a
notice of a claim pursuant to Section 2(b) hereof, the Company has director and
officer liability insurance in effect, the Company shall give prompt notice of
the commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

                (e) Selection of Counsel. In the event the Company shall be
obligated under Section 2(a) hereof to pay the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the
defense of such proceeding, with counsel approved by Indemnitee, upon the
delivery to Indemnitee of written notice of its election so to do. After
delivery of such notice, approval of such counsel by Indemnitee and the
retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred by
Indemnitee with respect to the same proceeding, provided that (i) Indemnitee
shall have the right to employ his or her counsel in any such proceeding at
Indemnitee's expense; and (ii) if (A) the employment of counsel by Indemnitee
has been previously



                                      -3-
<PAGE>   4

authorized by the Company, (B) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the
conduct of any such defense, or (C) the Company shall not, in fact, have
employed counsel to assume the defense of such proceeding, then the fees and
expenses of Indemnitee's counsel shall be at the expense of the Company.

        3.      Additional Indemnification Rights; Nonexclusivity.

                (a) Scope. Notwithstanding any other provision of this
Agreement, the Company hereby agrees to indemnify the Indemnitee to the fullest
extent permitted by law, notwithstanding that such indemnification is not
specifically authorized by the other provisions of this Agreement, the Company's
Articles of Incorporation, the Company's Bylaws or by statute. In the event of
any change in any applicable law, statute or rule which narrows the right of a
California corporation to indemnify a member of its board of directors or an
officer, such changes, to the extent not otherwise required by such law, statute
or rule to be applied to this Agreement shall have no effect on this Agreement
or the parties' rights and obligations hereunder.

                (b) Nonexclusivity. The indemnification provided by this
Agreement shall not be deemed exclusive of any rights to which Indemnitee may be
entitled under the Company's Articles of Incorporation, its Bylaws, any
agreement, any vote of shareholders or disinterested Directors, the Corporation
Law of the State of California, or otherwise, both as to action in Indemnitee's
official capacity and as to action in another capacity while holding such
office. The indemnification provided under this Agreement shall continue as to
Indemnitee for any action taken or not taken while serving in an indemnified
capacity even though he or she may have ceased to serve in such capacity at the
time of any action, suit or other covered proceeding.

        4. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred by him or her in the investigation, defense, appeal or settlement of
any civil or criminal action, suit or proceeding, but not, however, for the
total amount thereof, the Company shall nevertheless indemnify Indemnitee for
the portion of such expenses, judgments, fines or penalties to which Indemnitee
is entitled.

        5. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or applicable public policy may prohibit
the Company from indemnifying its directors and officers under this Agreement or
otherwise. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the Securities and
Exchange Commission to submit the question of indemnification to a court in
certain circumstances for a determination of the Company's right under public
policy to indemnify Indemnitee.

        6. Officer and Director Liability Insurance. The Company may, from time
to time, make the good faith determination whether or not it is practicable for
the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other



                                      -4-
<PAGE>   5

considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
director and officer liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company, but is an officer; or of the Company's key employees,
if Indemnitee is not an officer or director, but is a key employee.
Notwithstanding the foregoing, the Company shall have no obligation to obtain or
maintain such insurance if the Company determines in good faith that such
insurance is not reasonably available, if the premium costs for such insurance
are disproportionate to the amount of coverage provided, if the coverage
provided by such insurance is limited by exclusions so as to provide an
insufficient benefit, or if Indemnitee is covered by similar insurance
maintained by a subsidiary or parent of the Company. However, the Company's
decision whether or not to adopt and maintain such insurance shall not affect in
any way its obligations to indemnify its officers and directors under this
Agreement or otherwise.

        7. Severability. Nothing in this Agreement is intended to require or
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law. The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. The provisions of this Agreement shall be severable as provided
in this Section 7. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

        8. Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

                (a) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except with respect
to proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 317 of the California Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors has approved the initiation or bringing of such suit.

                (b) Lack of Good Faith. To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous.

                (c) Insured Claims. To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company.



                                      -5-
<PAGE>   6

                (d) Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        9.      Construction of Certain Phrases.

                (a) For purposes of this Agreement, references to the "Company"
shall include any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that if Indemnitee is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, Indemnitee shall stand in the same position under the
provisions of this Agreement with respect to the resulting or surviving
corporation as Indemnitee would have with respect to such constituent
corporation if its separate existence had continued.

                (b) For purposes of this Agreement, references to "other
enterprises," shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee or agent of the Company
which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan, its participants, or
beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan, Indemnitee shall be deemed to have acted in a
manner "not opposed to the best interests of the Company" as referred to in this
Agreement.

the commencement date of Indemnitee's employment as an Officer or Director of

Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys, fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all court costs and expenses, including attorneys' fees,

incurred by Indemnitee in defense of such action (including with respect to
Indemnitee's counterclaims and cross-claims made in such action), unless as a
part of such action the court determines that each of Indemnitee's material
defenses to such action were made in bad faith or were frivolous.

        14. Notice. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if

Committee, or a combination thereof, as determined by the Board. The Plan may be
administered by different administrative bodies with respect to different
classes of Optionees and, if permitted by the Applicable Laws, the Board may
authorize one or more officers to grant Options or Stock Purchase Rights under
the Plan.

               (b) ADMINISTRATION WITH RESPECT TO REPORTING PERSONS. With
respect to Options granted to Reporting Persons and Named Executives, the Plan
may (but need not) be administered so as to permit such Options to qualify for
the exemption set forth in Rule 16b-3 and to qualify as performance-based
compensation under Section 162(m) of the Code.

               (c) COMMITTEE COMPOSITION. If a Committee has been appointed
pursuant to this Section 4, such Committee shall continue to serve in its
designated capacity until otherwise directed by the Board. From time to time the
Board may increase the size of any Committee and appoint additional members
thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies (however caused) and remove all members of
a Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws and, in the case of a Committee administering
the Plan pursuant to Section 4(b) above, to the extent permitted or required by
Rule 16b-3 and Section 162(m) of the Code.

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



                                      -4-
<PAGE>   5

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

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

                      (iii) to determine whether and to what extent Options are
granted;

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

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

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

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

                      (viii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option has declined since the date the Option was granted and to
make any other amendments or adjustments to any Option that the Administrator
determines, in its discretion and under the authority granted to it under the
Plan, to be necessary or advisable, provided however that no amendment or
adjustment to an Option that would materially and adversely affect the rights of
any Optionee shall be made without the prior written consent of the Optionee;

                      (ix) to initiate an Option Exchange Program;

                      (x) to construe and interpret the terms of the Plan and
Options granted under the Plan; and

                      (xi) in order to fulfill the purposes of the Plan and
without amending the Plan, to modify grants of Options to Participants who are
foreign nationals or employed outside of the United States in order to recognize
differences in local law, tax policies or customs.

               (e) EFFECT OF ADMINISTRATOR'S DECISION. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Participants.

        5. ELIGIBILITY.

               (a) RECIPIENTS OF GRANTS. Nonstatutory Stock Options may be
granted to



                                      -5-
<PAGE>   6

Employees and Consultants. Incentive Stock Options may be granted
only to Employees; provided however that Employees of Affiliates shall not be
eligible to receive Incentive Stock Options. An Employee or Consultant who has
been granted an Option may, if he or she is otherwise eligible, be granted
additional Options.

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

               (c) AT-WILL RELATIONSHIP. The Plan shall not confer upon any
Participant any right with respect to continuation of employment or consulting
relationship with the Company, nor shall it interfere in any way with such
Optionee's right or the Company's right to terminate his or her employment or
consulting relationship at any time, with or without cause.

        6. TERM OF PLAN. The Plan shall become effective upon its adoption by
the Board. It shall continue in effect for a term of ten years unless sooner
terminated under Section 14 of the Plan.

        7. TERM OF OPTION. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement. However, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Option is granted, is a Ten Percent Holder,
the term of such Option shall be five years from the date of grant thereof or
such shorter term as may be provided in the Option Agreement.

        8. OPTION EXERCISE PRICE AND CONSIDERATION.

               (a) The per Share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Administrator and set forth in the applicable Option Agreement, but shall be
subject to the following:

                      (i) In the case of an Incentive Stock Option that is:

                             (A)    granted to an Employee who, at the time of
grant is a Ten Percent Holder, the per Share exercise price shall be no less
than 110% of the Fair Market Value per Share on the date of grant.

                             (B) granted to any other Employee, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.



                                      -6-
<PAGE>   7
                      (ii) In the case of a Nonstatutory Stock Option that is:

                             (A) granted prior to the date, if any, on which the
Common Stock becomes a Listed Security to a person who at the time of grant is a
Ten Percent Holder, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of the grant if required by the
Applicable Laws and, if not so required, shall be such price as is determined by
the Administrator.

                             (B) granted prior to the date, if any, on which
the Common Stock becomes a Listed Security to any other eligible person, the per
Share exercise price shall be no less than 85% of the Fair Market Value per
Share on the date of grant if required by the Applicable Laws and, if not so
required, shall be such price as is determined by the Administrator.

                      (iii)  Notwithstanding the foregoing, Options may be
granted with a per Share exercise price other than as required above pursuant to
a merger or other corporate transaction.

               (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash; (2)
check; (3) delivery of Optionee's promissory note with such recourse, interest,
security and redemption provisions as the Administrator determines to be
appropriate ; (4) cancellation of indebtedness; (5) other Shares that (x) in the
case of Shares acquired upon exercise of an Option, either have been owned by
the Optionee for more than six months on the date of surrender or such other
period as may be required to avoid a charge to the Company's earnings or were
not acquired, directly or indirectly, from the Company, and (y) have a Fair
Market Value on the date of surrender equal to the aggregate exercise price of
the Shares as to which such Option shall be exercised; (6) authorization for the
Company to retain from the total number of Shares as to which the Option is
exercised that number of Shares having a Fair Market Value on the date of
exercise equal to the exercise price for the total number of Shares as to which
the Option is exercised; (7) delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the broker, if
applicable, shall require to effect exercise of the Option and prompt delivery
to the Company of the sale or loan proceeds required to pay the exercise price
and any applicable withholding taxes; (8) any combination of the foregoing
methods of payment; or (9) such other consideration and method of payment for
the issuance of Shares to the extent permitted under the Applicable Laws. In
making its determination as to the type of consideration to accept, the
Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company, and the Administrator may refuse to
accept a particular form of consideration at the time of any Option exercise if,
in its sole discretion, acceptance of such form of consideration is not in the
best interests of the Company at such time.

        9. EXERCISE OF OPTION.

               (a) PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option
granted



                                      -7-
<PAGE>   8

hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, consistent with the term of the Plan and
reflected in the Option Agreement, including vesting requirements and/or
performance criteria with respect to the Company and/or the Optionee; provided
however, that, if required by the Applicable Laws, any Option granted prior to
the date, if any, upon which the Common Stock becomes a Listed Security shall
become exercisable at the rate of at least 20% per year over five years from the
date the Option is granted. In the event that any of the Shares issued upon
exercise of an Option (which exercise occurs prior to the date, if any, upon
which the Common Stock becomes a Listed Security) should be subject to a right
of repurchase in the Company's favor, such repurchase right shall, if required
by the Applicable Laws, lapse at the rate of at least 20% per year over five
years from the date the Option is granted. Notwithstanding the above, in the
case of an Option granted to an officer, Director or Consultant of the Company
or any Parent, Subsidiary or Affiliate of the Company, the Option may become
fully exercisable, or a repurchase right, if any, in favor of the Company shall
lapse, at any time or during any period established by the Administrator. The
Administrator shall have the discretion to determine whether and to what extent
the vesting of Options shall be tolled during any leave of absence.

        An Option may not be exercised for a fraction of a Share.

        An Option shall be deemed exercised when written notice of such exercise
has been given to the Company in accordance with the terms of the Option by the
person entitled to exercise the Option and the Company has received full payment
for the Shares with respect to which the Option is exercised. Full payment may,
as authorized by the Administrator, consist of any consideration and method of
payment allowable under Section 8(b) of the Plan. Until the issuance (as
evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing
such Shares, no right to vote or receive dividends or any other rights as a
shareholder shall exist with respect to the Optioned Stock, not withstanding the
exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate promptly upon exercise of the Option. No adjustment will be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 11 of the
Plan.

        Exercise of an Option in any manner shall result in a decrease in the
number of Shares that thereafter may be available, both for purposes of the Plan
and for sale under the Option, by the number of Shares as to which the Option is
exercised.

               (b) TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP. In the
event of termination of an Optionee's Continuous Service Status with the
Company, such Optionee may, but only within three months (or such other period
of time, not less than 30 days, as is determined by the Administrator, with such
determination in the case of an Incentive Stock Option being made at the time of
grant of the Option) after the date of such termination (but in no event later
than the expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that the Optionee was
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the Optionee does not exercise the Option to the



                                      -8-
<PAGE>   9
extent so entitled within the time specified above, the Option shall terminate
and the Optioned Stock underlying the unexercised portion of the Option shall
revert to the Plan. Unless otherwise determined by the Administrator, no
termination shall be deemed to occur and this Section 9(b) shall not apply if
(i) the Optionee is a Consultant who becomes an Employee, or (ii) the Optionee
is an Employee who becomes a Consultant.

               (c) DISABILITY OF OPTIONEE.

                      (i) Notwithstanding Section 9(b) above, in the event of
termination of an Optionee's Continuous Service Status as a result of his or her
total and permanent disability (within the meaning of Section 22(e)(3) of the
Code), such Optionee may, but only within twelve months (or such other period of
time as is determined by the Administrator, with such determination in the case
of an Incentive Stock Option made at the time of grant of the Option) from the
date of such termination (but in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise the Option
to the extent otherwise entitled to exercise it at the date of such termination.
To the extent that the Optionee was not entitled to exercise the Option at the
date of termination, or if the Optionee does not exercise such Option to the
extent so entitled within the time specified above, the Option shall terminate
and the Optioned Stock underlying the unexercised portion of the Option shall
revert to the Plan.

                      (ii) In the event of termination of an Optionee's
Continuous Service Status as a result of a disability which does not fall within
the meaning of total and permanent disability (as set forth in Section 22(e)(3)
of the Code), such Optionee may, but only within twelve months (or such other
period of time as is determined by the Administrator, with such determination in
the case of an Incentive Stock Option made at the time of grant of the Option)
from the date of such termination (but in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination. However, to the extent that such Optionee fails to exercise an
Option that is an Incentive Stock Option (within the meaning of Section 422 of
the Code) within three months of the date of such termination, the Option will
not qualify for Incentive Stock Option treatment under the Code. To the extent
that the Optionee was not entitled to exercise the Option at the date of
termination, or if the Optionee does not exercise such Option to the extent so
entitled within the time period specified above, the Option shall terminate and
the Optioned Stock underlying the unexercised portion of the Option shall revert
to the Plan.

               (d) DEATH OF OPTIONEE. In the event of the death of an Optionee
during the period of Continuous Service Status since the date of grant of the
Option, or within 30 days following termination of the Optionee's Continuous
Service Status, the Option may be exercised, at any time within twelve months
following the date of death (but in no event later than the expiration date of
the term of such Option as set forth in the Option Agreement), by such
Optionee's estate or by a person who acquired the right to exercise the Option
by bequest or inheritance, but only to the extent of the right to exercise that
had accrued at the date of death or, if earlier, the date of termination of the
Optionee's Continuous Service Status. To the extent that the Optionee was not
entitled to exercise the Option at the date of death or termination, as the



                                      -9-
<PAGE>   10
case may be, or if the Optionee does not exercise such Option to the extent so
entitled within the time specified above, the Option shall terminate and the
Optioned Stock underlying the unexercised portion of the Option shall revert to
the Plan.

               (e) EXTENSION OF EXERCISE PERIOD. The Administrator shall have
full power and authority to extend the period of time for which an Option is to
remain exercisable following termination of an Optionee's Continuous Status as
an Employee or Consultant from the periods set forth in Sections 9(b), 9(c) and
9(d) above or in the Option Agreement to such greater time as the Board shall
deem appropriate, provided, that in no event shall such Option be exercisable
later than the date of expiration of the term of such Option as set forth in the
Option Agreement.

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

        10. TAXES.

               (a) As a condition of the exercise of an Option or Stock Purchase
Right granted under the Plan, the Participant (or in the case of the
Participant's death, the person exercising the Option) shall make such
arrangements as the Administrator may require for the satisfaction of any
applicable federal, state, local or foreign withholding tax obligations that may
arise in connection with the exercise of an Option or Stock Purchase Right and
the issuance of Shares. The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

               (b) In the case of an Employee and in the absence of any other
arrangement, the Employee shall be deemed to have directed the Company to
withhold or collect from his or her compensation an amount sufficient to satisfy
such tax obligations from the next payroll payment otherwise payable after the
date of an exercise of the Option.

               (c) This Section 10(c) shall apply only after the date, if any,
upon which the Common Stock becomes a Listed Security. In the case of a
Participant other than an Employee (or in the case of an Employee where the next
payroll payment is not sufficient to satisfy such tax obligations, with respect
to any remaining tax obligations), in the absence of any other arrangement and
to the extent permitted under the Applicable Laws, the Participant shall be
deemed to have elected to have the Company withhold from the Shares to be issued
upon exercise of the Option or Stock Purchase Right that number of Shares having
a Fair Market Value determined as of the applicable Tax Date (as defined below)
equal to the amount required to be withheld. For purposes of this Section 10,
the Fair Market Value of the Shares to be withheld shall be determined on the
date that the amount of tax to be withheld is to be determined under the
Applicable Laws (the "Tax Date").

               (d) If permitted by the Administrator, in its discretion, a
Participant may satisfy his or her tax withholding obligations upon exercise of
an Option or Stock Purchase Right by surrendering to the Company Shares that (i)
in the case of Shares previously acquired from



                                      -10-
<PAGE>   11
the Company, have been owned by the Participant for more than six months on the
date of surrender, and (ii) have a Fair Market Value determined as of the
applicable Tax Date equal to the amount required to be withheld.

               (e) Any election or deemed election by a Participant to have
Shares withheld to satisfy tax withholding obligations under Section 10(c) or
(d) above shall be irrevocable as to the particular Shares as to which the
election is made and shall be subject to the consent or disapproval of the
Administrator. Any election by a Participant under Section 10(d) above must be
made on or prior to the applicable Tax Date.

               (f) In the event an election to have Shares withheld is made by a
Participant and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Participant shall receive
the full number of Shares with respect to which the Option or Stock Purchase
Right is exercised but such Participant shall be unconditionally obligated to
tender back to the Company the proper number of Shares on the Tax Date.

        11. NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS. Options
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred or disposed of in any manner other than by will or by the laws of
descent or distribution; provided however that, after the date, if any, upon
which the Common Stock becomes a Listed Security, the Administrator may in its
discretion grant transferable Nonstatutory Stock Options pursuant to Option
Agreements specifying (i) the manner in which such Nonstatutory Stock Options
are transferable and (ii) that any such transfer shall be subject to the
Applicable Laws. The designation of a beneficiary by an Optionee will not
constitute a transfer. An Option or Stock Purchase Right may be exercised,
during the lifetime of the holder of the Option or Stock Purchase Right, only by
such holder or a transferee permitted by this Section 11.

        12. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, CORPORATE TRANSACTIONS
AND CERTAIN OTHER TRANSACTIONS.

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



                                      -11-
<PAGE>   12
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of Shares of Common Stock subject to an Option.

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

               (c) CORPORATE TRANSACTIONS. In the event of a Corporate
Transaction, each outstanding Option shall be assumed or an equivalent option
shall be substituted by the successor corporation (or a Parent or Subsidiary of
such successor corporation), unless the successor corporation does not agree to
assume the outstanding Options or substitute equivalent options, in which case
the outstanding Options shall terminate upon the consummation of the
transaction..

               For purposes of this Section 12(c), an Option shall be considered
assumed, without limitation, if, at the time of issuance of the stock or other
consideration upon a Corporate Transaction, each Optionee would be entitled to
receive upon exercise of an Option the same number and kind of shares of stock
or the same amount of property, cash or securities as the Optionee would have
been entitled to receive upon the occurrence of such transaction if the Optionee
had been, immediately prior to the transaction, the holder of the number of
Shares of Common Stock covered by the Option at such time (after giving effect
to any adjustments in the number of Shares covered by the Option as provided for
in this Section 12); provided however that if such consideration received in the
transaction is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon exercise of the Option to be
solely common stock of the successor corporation or its Parent equal to the Fair
Market Value of the per Share consideration received by holders of Common Stock
in the transaction.

               (d) CERTAIN DISTRIBUTIONS. In the event of any distribution to
the Company's shareholders of securities of any other entity or other assets
(other than dividends payable in cash or stock of the Company) without receipt
of consideration by the Company, the Administrator may, in its discretion,
appropriately adjust the price per Share of Common Stock covered by each
outstanding Option to reflect the effect of such distribution.

        13. TIME OF GRANTING OPTIONS. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator;
provided however that in the case of any Incentive Stock Option, the grant date
shall be the later of the date on which the Administrator makes the
determination granting such Incentive Stock Option or the date of commencement
of the Optionee's employment relationship with the Company. Notice of the
determination shall be given to each Employee or Consultant to whom an Option is
so granted within a reasonable time after the date of such grant.

        14. AMENDMENT AND TERMINATION OF THE PLAN.



                                      -12-
<PAGE>   13

               (a) AUTHORITY TO AMEND OR TERMINATE. The Board may at any time
amend, alter, suspend, discontinue or terminate the Plan, but no amendment,
alteration, suspension, discontinuation or termination (other than an adjustment
made pursuant to Section 13 above) shall be made that would materially and
adversely affect the rights of any Optionee under any outstanding grant, without
his or her consent. In addition, to the extent necessary and desirable to comply
with the Applicable Laws, the Company shall obtain shareholder approval of any
Plan amendment in such a manner and to such a degree as required.

               (b) EFFECT OF AMENDMENT OR TERMINATION. No amendment or
termination of the Plan shall materially and adversely affect Options already
granted, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company.

        15. CONDITIONS UPON ISSUANCE OF SHARES. Notwithstanding any other
provision of the Plan or any agreement entered into by the Company pursuant to
the Plan, the Company shall not be obligated, and shall have no liability for,
failure to issue or deliver any Shares under the Plan unless such issuance or
delivery would comply with the Applicable Laws, with such compliance determined
by the Company in consultation with its legal counsel.

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

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

        17. OPTION AGREEMENTS. Options shall be evidenced by Option Agreements
in such form(s) as the Administrator shall from time to time approve.

        18. SHAREHOLDER APPROVAL. If required by the Applicable Laws,
continuance of the Plan shall be subject to approval by the shareholders of the
Company within twelve months before or after the date the Plan is adopted. Such
shareholder approval shall be obtained in the degree and manner required under
the Applicable Laws.

        19. INFORMATION AND DOCUMENTS TO OPTIONEES. Prior to the date, if any,
upon which the Common Stock becomes a Listed Security and if required by the
Applicable Laws, the Company shall provide financial statements at least
annually to each Optionee during the period such Optionee has one or more
Options outstanding, and in the case of an individual who acquired Shares
pursuant to the Plan, during the period such individual owns such Shares. The
Company shall not be required to provide such information if the issuance of
Options under the Plan is limited to key employees whose duties in connection
with the Company assure their access to equivalent information. In addition, at
the time of issuance of any securities under the Plan, the Company shall provide
to the Optionee a copy of the Plan and any agreement(s) pursuant to which
securities granted under the Plan are issued.

stockholder-approved amendment to the Plan, and (ii) all or a portion of such
additional Shares are to be issued with respect to one or more Offering Periods
that are underway at the time of such increase ("Additional Shares"), and (iii)
the Fair Market Value of a Share of Common Stock on the date of such increase

the grant, such Employee (or any other person whose stock would be attributed to
such Employee pursuant to Section 424(d) of the Code) would own capital stock of
the Company and/or hold outstanding options to purchase stock possessing five
percent (5%) or more of the total combined voting power or value of all classes
of stock of the Company or of any subsidiary of the Company, or (ii) if such
option would permit his or her rights to purchase stock under all employee stock
purchase plans (described in Section 423 of the Code) of the Company and its
Subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars
($25,000) of the Fair Market Value (as defined in Section 7(b) below) of such
stock (determined at the time such option is granted) for each calendar year in
which such option is outstanding at any time.

        4. OFFERING PERIODS AND PURCHASE PERIODS.

                (a) OFFERING PERIODS. The Plan shall be implemented by a series
of Offering Periods of twenty-four (24) months' duration, with new Offering
Periods commencing on or about February 1 and August 1 of each year (or at such
other time or times as may be determined by the Board of Directors). The first

prior to the scheduled beginning of the first Offering Period to be affected.

                (b) PURCHASE PERIODS. Each Offering Period shall consist of four
(4) consecutive purchase periods of six (6) months' duration. The last day of
each Purchase Period shall be the "Purchase Date" for such Purchase Period. A
Purchase Period commencing on February 1 shall end on the next July 31. A
Purchase Period commencing on August 1 shall end on the next January 31. The
first Purchase Period shall commence on the IPO Date and shall end on January
31, 2000. The Board of Directors of the Company shall have the power to change
the duration and/or frequency of Purchase Periods with respect to future
purchases without stockholder approval if such change is announced at least five
(5) days prior to the scheduled beginning of the first Purchase Period to be

        5. PARTICIPATION.

                (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement on the form provided by the Company and
filing it with the Company's payroll office prior to the applicable Offering
Date, unless a later time for filing the subscription agreement is set by the
Board for all eligible Employees with respect to a given Offering Period. The
subscription agreement shall set forth the percentage of the participant's
Compensation (subject to Section 6(a) below) to be paid as Contributions
pursuant to the Plan.

                (b) Payroll deductions shall commence on the first payroll
following the Offering Date and shall end on the last payroll paid on or prior
to the last Purchase Period of the Offering Period to which the subscription
agreement is applicable, unless sooner terminated by the participant as provided
in Section 10.

        6. METHOD OF PAYMENT OF CONTRIBUTIONS.

                (a) A participant shall elect to have payroll deductions made on
each payday during the Offering Period in an amount not less than one percent
(1%) and not more than fifteen percent (15%) (or such greater percentage as the
Board may establish from time to time before an Offering Date) of such
participant's Compensation on each payday during the Offering Period. All
payroll deductions made by a participant shall be credited to his or her account
under the Plan. A participant may not make any additional payments into such
account.

                (b) A participant may discontinue his or her participation in
the Plan as provided in Section 10, or, on one occasion only during a Purchase
Period may increase and on one occasion only during a Purchase Period may
decrease the rate of his or her Contributions with respect to the Offering
Period by completing and filing with the Company a new subscription agreement
authorizing a change in the payroll deduction rate. The change in rate shall be
effective as of the beginning of the next calendar month following the date of
filing of the new subscription agreement, if the agreement is filed at least ten
(10) business days prior to such date and, if not, as of the beginning of the
next succeeding calendar month.

                (c) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) herein, a
participant's payroll deductions may be decreased during any Purchase Period to
0%. Payroll deductions shall re-commence at the rate provided in such
participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10.

        7. GRANT OF OPTION.

                (a) On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Purchase Date a number of Shares of the Company's Common Stock
determined by dividing such Employee's Contributions accumulated prior to such
Purchase Date and retained in the participant's account as of the Purchase Date
by the applicable Purchase Price; provided however



                                      -4-
<PAGE>   5

that the maximum number of Shares an Employee may purchase during each Purchase
Period shall be 2,000 Shares (subject to any adjustment pursuant to Section 19
below), and provided further that such purchase shall be subject to the
limitations set forth in Sections 3(b) and 13.

                (b) The fair market value of the Company's Common Stock on a
given date (the "Fair Market Value") shall be determined by the Board in its
discretion based on the closing sales price of the Common Stock for such date
(or, in the event that the Common Stock is not traded on such date, on the
immediately preceding trading date), as reported by the National Association of
Securities Dealers Automated Quotation (Nasdaq) National Market or, if such
price is not reported, the mean of the bid and asked prices per share of the
Common Stock as reported by Nasdaq or, in the event the Common Stock is listed
on a stock exchange, the Fair Market Value per share shall be the closing sales
price on such exchange on such date (or, in the event that the Common Stock is
not traded on such date, on the immediately preceding trading date), as reported
in The Wall Street Journal. For purposes of the Offering Date under the first
Offering Period under the Plan, the Fair Market Value of a share of the Common
Stock of the Company shall be the Price to Public as set forth in the final
prospectus filed with the Securities and Exchange Commission pursuant to Rule
424 under the Securities Act of 1933, as amended.

        8. EXERCISE OF OPTION. Unless a participant withdraws from the Plan as
provided in Section 10, his or her option for the purchase of Shares will be
exercised automatically on each Purchase Date of an Offering Period, and the
maximum number of full Shares subject to the option will be purchased at the
applicable Purchase Price with the accumulated Contributions in his or her
account. No fractional Shares shall be issued. The Shares purchased upon
exercise of an option hereunder shall be deemed to be transferred to the
participant on the Purchase Date. During his or her lifetime, a participant's
option to purchase Shares hereunder is exercisable only by him or her.

        9. DELIVERY. As promptly as practicable after each Purchase Date of each
Offering Period, the Company shall arrange the delivery to each participant, as
appropriate, the Shares purchased upon exercise of his or her option. No
fractional Shares shall be purchased; any payroll deductions accumulated in a
participant's account which are not sufficient to purchase a full Share shall be
retained in the participant's account for the subsequent Purchase Period or
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 below. Any other amounts left over in a participant's account after a
Purchase Date shall be returned to the participant.

        10. VOLUNTARY WITHDRAWAL; TERMINATION OF EMPLOYMENT.

                (a) A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
each Purchase Date by giving written notice to the Company. All of the
participant's Contributions credited to his or her account will be paid to him
or her promptly after receipt of his or her notice of withdrawal and his or her
option for the current period will be automatically terminated, and no further
Contributions for the purchase of Shares will be made during the Offering
Period.



                                      -5-
<PAGE>   6

                (b) Upon termination of the participant's Continuous Status as
an Employee prior to the Purchase Date of an Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and his or her option will
be automatically terminated.

                (c) In the event an Employee fails to remain in Continuous
Status as an Employee of the Company for at least twenty (20) hours per week
during the Offering Period in which the employee is a participant, he or she
will be deemed to have elected to withdraw from the Plan and the Contributions
credited to his or her account will be returned to him or her and his or her
option terminated.

                (d) A participant's withdrawal from an offering will not have
any effect upon his or her eligibility to participate in a succeeding offering
or in any similar plan which may hereafter be adopted by the Company.

        11. AUTOMATIC WITHDRAWAL. If the Fair Market Value of the Shares on any
Purchase Date of an Offering Period is less than the Fair Market Value of the
Shares on the Offering Date for such Offering Period, then every participant
shall automatically (i) be withdrawn from such Offering Period at the close of
such Purchase Date and after the acquisition of Shares for such Purchase Period,
and (ii) be enrolled in the Offering Period commencing on the first business day
subsequent to such Purchase Period.

        12. INTEREST. No interest shall accrue on the Contributions of a
participant in the Plan.

        13. STOCK.

                (a) Subject to adjustment as provided in Section 19, the maximum
number of Shares which shall be made available for sale under the Plan shall be
1,000,000 Shares, plus an annual increase on the first day of each of the
Company's fiscal years beginning in 2001, 2002, 2003, 2004 and 2005 equal to the
lesser of (i) 250,000 Shares, (ii) one percent (1%) of the Shares outstanding on
the last day of the immediately preceding fiscal year, or (iii) such lesser
number of Shares as is determined by the Board. If the Board determines that, on
a given Purchase Date, the number of shares with respect to which options are to
be exercised may exceed (i) the number of shares of Common Stock that were
available for sale under the Plan on the Offering Date of the applicable
Offering Period, or (ii) the number of shares available for sale under the Plan
on such Purchase Date, the Board may in its sole discretion provide (x) that the
Company shall make a pro rata allocation of the Shares of Common Stock available
for purchase on such Offering Date or Purchase Date, as applicable, in as
uniform a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Purchase Date, and continue all Offering Periods then in
effect, or (y) that the Company shall make a pro rata allocation of the shares
available for purchase on such Offering Date or Purchase Date, as applicable, in
as uniform a manner as shall be practicable and as it shall determine in its
sole discretion to be equitable among all participants exercising options to
purchase Common Stock on such Purchase Date, and terminate any or all Offering
Periods then in effect pursuant to Section 20 below. The Company may make pro
rata allocation



                                      -6-
<PAGE>   7

of the Shares available on the Offering Date of any applicable Offering Period
pursuant to the preceding sentence, notwithstanding any authorization of
additional Shares for issuance under the Plan by the Company's stockholders
subsequent to such Offering Date.

                (b) The participant shall have no interest or voting right in
Shares covered by his or her option until such option has been exercised.

                (c) Shares to be delivered to a participant under the Plan will
be registered in the name of the participant or in the name of the participant
and his or her spouse.

        14. ADMINISTRATION. The Board, or a committee named by the Board, shall
supervise and administer the Plan and shall have full power to adopt, amend and
rescind any rules deemed desirable and appropriate for the administration of the
Plan and not inconsistent with the Plan, to construe and interpret the Plan, and
to make all other determinations necessary or advisable for the administration
of the Plan.

        15. DESIGNATION OF BENEFICIARY.

                (a) A participant may file a written designation of a
beneficiary who is to receive any Shares and cash, if any, from the
participant's account under the Plan in the event of such participant's death
subsequent to the end of a Purchase Period but prior to delivery to him or her
of such Shares and cash. In addition, a participant may file a written
designation of a beneficiary who is to receive any cash from the participant's
account under the Plan in the event of such participant's death prior to the
Purchase Date of an Offering Period. If a participant is married and the
designated beneficiary is not the spouse, spousal consent shall be required for
such designation to be effective.

                (b) Such designation of beneficiary may be changed by the
participant (and his or her spouse, if any) at any time by written notice. In
the event of the death of a participant and in the absence of a beneficiary
validly designated under the Plan who is living at the time of such
participant's death, the Company shall deliver such Shares and/or cash to the
executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such Shares and/or cash to the
spouse or to any one or more dependents or relatives of the participant, or if
no spouse, dependent or relative is known to the Company, then to such other
person as the Company may designate.

                16. TRANSFERABILITY. Neither Contributions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive Shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 15) by the participant. Any such attempt
at assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds in
accordance with Section 10.



                                      -7-
<PAGE>   8

        17. USE OF FUNDS. All Contributions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such Contributions.

        18. REPORTS. Individual accounts will be maintained for each participant
in the Plan. Statements of account will be given to participating Employees at
least annually, which statements will set forth the amounts of Contributions,
the per Share Purchase Price, the number of Shares purchased and the remaining
cash balance, if any.

        19. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE TRANSACTIONS.

                (a) ADJUSTMENT. Subject to any required action by the
stockholders of the Company, the number of Shares covered by each option under
the Plan which has not yet been exercised and the number of Shares which have
been authorized for issuance under the Plan but have not yet been placed under
option (collectively, the "Reserves"), as well as the maximum number of shares
of Common Stock which may be purchased by a participant in a Purchase Period,
the number of shares of Common Stock set forth in Section 13(a)(i) above, and
the price per Share of Common Stock covered by each option under the Plan which
has not yet been exercised, shall be proportionately adjusted for any increase
or decrease in the number of issued Shares resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common Stock
(including any such change in the number of Shares of Common Stock effected in
connection with a change in domicile of the Company), or any other increase or
decrease in the number of Shares effected without receipt of consideration by
the Company; provided however that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issue by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of Shares subject to an option.

                (b) CORPORATE TRANSACTIONS. In the event of a dissolution or
liquidation of the Company, any Purchase Period and Offering Period then in
progress will terminate immediately prior to the consummation of such action,
unless otherwise provided by the Board. In the event of a Corporate Transaction,
each option outstanding under the Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or Subsidiary of
such successor corporation. In the event that the successor corporation refuses
to assume or substitute for outstanding options, each Purchase Period and
Offering Period then in progress shall be shortened and a new Purchase Date
shall be set (the "New Purchase Date"), as of which date any Purchase Period and
Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the transaction and the Board shall
notify each participant in writing, at least ten (10) days prior to the New
Purchase Date, that the Purchase Date for his or her option has been changed to
the New Purchase Date and that his or her option will be exercised automatically
on the New Purchase Date, unless prior to such date he or she has withdrawn from
the Offering Period as provided in Section 10. For purposes of this Section 19,
an option granted under the Plan shall be deemed to be assumed, without
limitation, if, at the time of issuance of the stock or other consideration upon
a Corporate Transaction, each



                                      -8-
<PAGE>   9

holder of an option under the Plan would be entitled to receive upon exercise of
the option the same number and kind of shares of stock or the same amount of
property, cash or securities as such holder would have been entitled to receive
upon the occurrence of the transaction if the holder had been, immediately prior
to the transaction, the holder of the number of Shares of Common Stock covered
by the option at such time (after giving effect to any adjustments in the number
of Shares covered by the option as provided for in this Section 19); provided
however that if the consideration received in the transaction is not solely
common stock of the successor corporation or its parent (as defined in Section
424(e) of the Code), the Board may, with the consent of the successor
corporation, provide for the consideration to be received upon exercise of the
option to be solely common stock of the successor corporation or its parent
equal in Fair Market Value to the per Share consideration received by holders of
Common Stock in the transaction.

        The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per Share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of Shares of its outstanding Common
Stock, and in the event of the Company's being consolidated with or merged into
any other corporation.

        20. AMENDMENT OR TERMINATION.

                (a) The Board may at any time and for any reason terminate or
amend the Plan. Except as provided in Section 19, no such termination of the
Plan may affect options previously granted, provided that the Plan or an
Offering Period may be terminated by the Board on a Purchase Date or by the
Board's setting a new Purchase Date with respect to an Offering Period and
Purchase Period then in progress if the Board determines that termination of the
Plan and/or the Offering Period is in the best interests of the Company and the
stockholders or if continuation of the Plan and/or the Offering Period would
cause the Company to incur adverse accounting charges as a result of a change
after the effective date of the Plan in the generally accepted accounting rules
applicable to the Plan. Except as provided in Section 19 and in this Section 20,
no amendment to the Plan shall make any change in any option previously granted
which adversely affects the rights of any participant. In addition, to the
extent necessary to comply with Rule 16b-3 under the Exchange Act, or under
Section 423 of the Code (or any successor rule or provision or any applicable
law or regulation), the Company shall obtain stockholder approval in such a
manner and to such a degree as so required.

                (b) Without stockholder consent and without regard to whether
any participant rights may be considered to have been adversely affected, the
Board (or its committee) shall be entitled to change the Offering Periods and
Purchase Periods, limit the frequency and/or number of changes in the amount
withheld during an Offering Period, establish the exchange ratio applicable to
amounts withheld in a currency other than U.S. dollars, permit payroll
withholding in excess of the amount designated by a participant in order to
adjust for delays or mistakes in the Company's processing of properly completed
withholding elections, establish reasonable waiting and adjustment periods
and/or accounting and crediting procedures to ensure that amounts applied toward
the purchase of Common Stock for each participant properly correspond with



                                      -9-
<PAGE>   10

amounts withheld from the participant's Compensation, and establish such other
limitations or procedures as the Board (or its committee) determines in its sole
discretion advisable which are consistent with the Plan.

        21. NOTICES. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        22. CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such Shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, applicable state securities laws and the requirements of
any stock exchange upon which the Shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

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

        23. TERM OF PLAN; EFFECTIVE DATE. The Plan shall become effective upon
the IPO Date. It shall continue in effect for a term of twenty (20) years unless
sooner terminated under Section 20.

        24. ADDITIONAL RESTRICTIONS OF RULE 16b-3. The terms and conditions of
options granted hereunder to, and the purchase of Shares by, persons subject to
Section 16 of the Exchange Act shall comply with the applicable provisions of
Rule 16b-3. This Plan shall be deemed to contain, and such options shall
contain, and the Shares issued upon exercise thereof shall be subject to, such
additional conditions and restrictions as may be required by Rule 16b-3 to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

        2. I elect to have Contributions in the amount of ____% of my
Compensation, as those terms are defined in the Plan, applied to this purchase.
I understand that this amount must not be less than 1% and not more than 15% of
my Compensation during the Offering Period. (Please note that no fractional
percentages are permitted).

        3. I hereby authorize payroll deductions from each paycheck during the
Offering Period at the rate stated in Item 2 of this Subscription Agreement. I
understand that all payroll deductions made by me shall be credited to my
account under the Plan and that I may not make any additional payments into such
account. I understand that all payments made by me shall be accumulated for the
purchase of shares of Common Stock at the applicable purchase price determined
in accordance with the Plan. I further understand that, except as otherwise set
forth in the Plan, shares will be purchased for me automatically on the Purchase
Date of each Offering Period unless I otherwise withdraw from the Plan by giving
written notice to the Company for such purpose.

        4. I understand that I may discontinue at any time prior to the Purchase
Date my participation in the Plan as provided in Section 10 of the Plan. I also
understand that I can increase or decrease the rate of my Contributions on one
occasion only with respect to any increase and one occasion only with respect to
any decrease during any Purchase Period by completing and filing a new
Subscription Agreement with such increase or decrease taking effect as of the
beginning of the calendar month following the date of filing of the new
Subscription Agreement, if filed at least ten (10) business days prior to the
beginning of such month. Further, I may change the rate of deductions for future
Offering Periods by filing a new Subscription Agreement, and any such change
will be effective as of the beginning of the next Offering Period. In addition,
I acknowledge that, unless I discontinue my participation in the Plan as
provided in Section 10 of the Plan, my election will continue to be effective
for each successive Offering Period.



                                      -11-
<PAGE>   12

        5. I have received a copy of the Company's most recent description of
the Plan and a copy of the complete "Netro Corporation 1999 Employee Stock
Purchase Plan." I understand that my participation in the Plan is in all
respects subject to the terms of the Plan.

        6. Shares purchased for me under the Plan should be issued in the
name(s) of (name of employee or employee and spouse only):

                                            ____________________________________

                                            ____________________________________

        7. In the event of my death, I hereby designate the following as my
beneficiary(ies) to receive all payments and shares due to me under the Plan:



NAME:  (Please print)                       ____________________________________
                                            (First)       (Middle)        (Last)

                                            ____________________________________

        8. I understand that if I dispose of any shares received by me pursuant
to the Plan within 2 years after the Offering Date (the first day of the
Offering Period during which I purchased such shares) or within 1 year after the
Purchase Date, I will be treated for federal income tax purposes as having
received ordinary compensation income at the time of such disposition in an
amount equal to the excess of the fair market value of the shares on the
Purchase Date over the price which I paid for the shares, regardless of whether
I disposed of the shares at a price less than their fair market value at the
Purchase Date. The remainder of the gain or loss, if any, recognized on such
disposition will be treated as capital gain or loss.

        I hereby agree to notify the Company in writing within 30 days after the
date of any such disposition, and I will make adequate provision for federal,
state or other tax withholding obligations, if any, which arise upon the
disposition of the Common Stock. The Company may, but will not be obligated to,
withhold from my compensation the amount necessary to meet any applicable
withholding obligation including any withholding necessary to make available to
the Company any tax deductions or benefits attributable to the sale or early
disposition of Common Stock by me.

        9. If I dispose of such shares at any time after expiration of the
2-year and 1-year holding periods, I understand that I will be treated for
federal income tax purposes as having received compensation income only to the
extent of an amount equal to the lesser of (1) the excess of the fair market
value of the shares at the time of such disposition over the purchase price
which I paid for the shares under the option, or (2) 15% of the fair market
value of the



                                       -2-

shares on the Offering Date. The remainder of the gain or loss, if any,
recognized on such disposition will be treated as capital gain or loss.

        I understand that this tax summary is only a summary and is subject to
change. I further understand that I should consult a tax advisor concerning the
tax implications of the purchase and sale of stock under the Plan.

        10. I hereby agree to be bound by the terms of the Plan. The
effectiveness of this Subscription Agreement is dependent upon my eligibility to
participate in the Plan.

                                 LEASE AGREEMENT

                                    (PHASE I)

        1. PARTIES: This Lease Agreement ("Lease") is entered into on this 6th
day of May, 1990, between JOHN A. SOBRATO, Trustee Under Trust Agreement Dated
August 29, 1979, as Amended, SOBRATO INTERESTS II, a California general
partnership, and JOHN MICHAEL SOBRATO or his Successor, Trustee Under Revocable
Trust Agreement dated April 28, 1989, as amended, FBO Ann Sobrato (collectively,
"Landlord") and PYRAMID TECHNOLOGY CORPORATION, a Delaware corporation
("Tenant").

        2. PREMISES:

               A. Premises: Landlord hereby leases to Tenant, and Tenant
leases from Landlord, those certain Premises with the appurtenances, situated in
the City of San Jose, County of Santa Clara, State of California, and more
particularly described as follows:

               A one-story building to be constructed by Landlord consisting of
               101,552 square feet ("Building") on a portion of a site
               consisting of three buildings totaling 280,784 square feet (the
               "Project") on that certain real property at the southeast corner
               of North First Street and Rose Orchard Way whose assessor's
               parcel numbers are 097-03-043 and APN 097-03-044 and more
               particularly described in Exhibit "A" attached hereto and
               incorporated herein by reference. During that period of time
               which Tenant has the exclusive right to occupy the Project,
               Tenant shall have the exclusive use, without charge, of
               approximately 975 parking spaces in the Project as may be
               decreased due to a reconfiguration of the dock area (which
               constitute all of the parking spaces in the Project).

               B. Remeasurement: Upon Substantial Completion of the Premises
(as described in the Construction Addendum to Lease attached to the Lease as
Exhibit B" and incorporated herein by reference), Tenant may elect to have the
Premises measured by Tenant's Interior Improvement Architect, as defined in the
Construction Addendum (measured from the exterior of the exterior walls of the
Building and including one-half of the covered loading docks but excluding any
other outside areas or canopies). If the actual square footage differs from the
amount stated above, the monthly rent hereunder shall be adjusted by multiplying
One and 10/100 Dollars ($1.10) times the actual square feet of the Building and
the Tenant Improvement Allowance shall be adjusted by multiplying Thirty-Seven
and No/100 Dollars ($37.00) times the actual square feet of the Building. The
square footage, if so remeasured by Tenant, shall be substituted for that set
forth herein for purposes of this Lease.

        3. USE: Tenant shall use the Premises only for legally permitted uses.

        4. TERM AND RENTAL: The term of this Lease ("Lease Term") shall commence
on the "Commencement Date" (as defined in Paragraph 7 hereof). The Lease Term
shall expire on September 14, 2001. The monthly rent shall be paid without
deduction or offset (except as otherwise set forth herein), in monthly
installments of One Hundred Eleven Thousand Seven

<PAGE>   7
Hundred Seven and 20/100 Dollars ($111,707.20) due on or before the first day of
each calendar month during the Lease Term. Said rental shall be paid in lawful
money of the United States of America, and shall be paid to Landlord at such
place or places as may be designated from time to time by Landlord. Rent for any
period less than a calendar month shall be prorated based on a thirty (30) day
month.

               A Rental Adjustment: On that date that is thirty (30) months
after the Commencement Date of the Lease, and on each date which is thirty (30)
months after the first adjustment date (each of the foregoing is referred to as
the "Adjustment Date"), the then payable monthly rent shall be subject to
adjustment based on the increase, if any, in the Consumer Price Index. The basis
for computing the adjustment shall be the U.S. Department of Labor, Bureau of
Labor Statistic's Consumer Price Index for All Urban Consumers, All Items,
1982-84=100, for the San Francisco-Oakland-San Jose area ("Index"). The Index
most recently published preceding the commencement of the Lease shall be
considered the "Base Index." If the Index most recently published preceding the
Adjustment Date ("Comparison Index") is greater than the Base Index, the then
payable monthly rent shall be increased by multiplying the initial monthly rent
by a fraction, the numerator of which is the Comparison Index and the
denominator of which is the Base Index. Within thirty (30) days after each
adjustment as set forth herein, Landlord shall furnish a statement to Tenant
setting forth the rental adjustment determined by reference to the foregoing,
and the method by which Landlord has calculated the same. Landlord's calculation
of the rent escalation shall be conclusive and binding unless Tenant objects to
said calculation within a sixty (60) day period after Tenant's receipt of such
written statement. If the Index base year is changed so that it differs from
1982-84=100, the Index shall be converted in accordance with the conversion
factor published by the United States Department of Labor, Bureau of Labor
Statistics. If the Index is discontinued or revised during the term, such other
government index or computation with which it is replaced shall be used in order
to obtain substantially the same result as would be obtained if the index had
not been discontinued or revised. In no event shall the monthly rent immediately
after the Adjustment Date be less than one hundred seven and one-half percent
(107 1/2%) nor more than one hundred twenty percent (120%) than the monthly rent
immediately before the Adjustment Date.

        5. SECURITY DEPOSIT:

               A. Cash Security Deposit: Within three (3) business days after
both parties' execution of this Lease, Tenant shall deposit with Landlord the
sum of One Hundred Eleven Thousand Seven Hundred Seven and 20/100 Dollars
($111,707.20) as a security deposit. If Tenant defaults with respect to any
provisions of this Lease, including, but not limited to, the provisions relating
to payment of rent or other charges, Landlord may, to the extent reasonably
necessary to remedy Tenant's default, use all or any part of said deposit for
the payment of rent or other charges in default or the payment of any reasonable
amount which Landlord may spend or become obligated to spend by reason of
Tenant's default or to compensate Landlord for any other loss or damage which
Landlord may suffer by reason of Tenant's default. If any portion of said
deposit is so used or applied, Tenant shall, within ten (10) days after written
demand therefor, deposit cash with Landlord in an amount sufficient to restore
said deposit to the full amount hereinabove stated and shall pay to Landlord
such other sums as shall be necessary to


                                      -2-
<PAGE>   8
reimburse Landlord for any sums paid by Landlord. Said deposit shall be returned
to Tenant within thirty (30) days after the expiration of the Lease Term less
any amount deducted in accordance with this paragraph, together with Landlord's
written notice itemizing the amounts and purposes for such retention. In the
event of termination of Landlord's interest in this Lease, Landlord shall
transfer said deposit to Landlord's successor in interest.

               B. Letter of Credit: Notwithstanding the foregoing provisions
of this paragraph 5, Landlord agrees that in lieu of a cash security deposit,
Tenant may deposit a letter of credit in a form reasonably acceptable to
Landlord. Landlord shall be entitled to draw against the letter of credit at any
time that Tenant has committed a default under this Lease, provided that
Landlord certifies to the issuer of the letter of credit under penalty of
perjury that Tenant is in default under the Lease (as default is defined in
paragraph 22 of this Lease). Tenant shall keep the letter of credit in effect
during the entire Lease Term, as the same may be extended, plus a period of four
(4) weeks thereafter. At least thirty (30) days prior to expiration of any
letter of credit, the term thereof shall be renewed or extended. Subject to
Tenant's cure rights under Paragraph 22, Tenant's failure to so renew or extend
the letter of credit shall be a material default of this Lease by Tenant. If
Landlord draws against the letter of credit, Tenant shall replenish the existing
letter of credit or cause a new letter of credit to be issued such that the
aggregate amount of letters of credit available to Landlord at all times during
the Lease Term is the amount of the security deposit originally required.

        6. LATE CHARGES: Tenant hereby acknowledges that late payment by Tenant
to Landlord of rent and other sums due hereunder will cause Landlord to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
administrative, processing, accounting charges, and late charges, which may be
imposed on Landlord by the terms of any contract, revolving credit, mortgage or
trust deed covering the Premises. Accordingly, if any installment of rent or any
other sum due from Tenant shall not be received by Landlord or Landlord's
designee within ten (10) days after Tenant's receipt of written notice that such
amount is delinquent, Tenant shall pay to Landlord a late charge equal to four
percent (4%) of such overdue amount which shall be due and payable with the
payment then delinquent. The parties hereby agree that such late charge
represents a fair and reasonable estimate of the costs Landlord will incur by
reason of late payment by Tenant. Acceptance of such late charge by Landlord
shall in no event constitute a waiver of Tenant's default with respect to such
overdue amount, nor prevent Landlord from exercising any of the other rights and
remedies granted hereunder.

        7. CONSTRUCTION AND POSSESSION:

               A. Construction of Improvements: The "Building Shell" and
"Interior Improvements" shall be constructed by Landlord under the terms and
conditions of that certain Construction Addendum to Lease attached hereto as
Exhibit "B" (the "Construction Addendum") The term of the Lease shall not
commence (the "Commencement Date") until the later of December 15, 1990, or the
date on which the Premises are "substantially Completed" as defined in the
Construction Addendum. Notwithstanding the foregoing, Tenant may elect to occupy
the Premises for the conduct of its business prior to December 15, 1990 if the
Premises are


                                      -3-
<PAGE>   9
Substantially Completed before such date. In the event of such early occupancy,
and provided the Premises are Substantially Completed, Tenant shall begin paying
rent as of the date of such occupancy for the conduct of its business, and
Tenant's occupancy shall be subject to the terms and conditions of this Lease.

               B. Failure to Deliver Possession: If Landlord, for any reason
whatsoever, cannot deliver possession of the Premises to Tenant on the scheduled
commencement date of December 15, 1990, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant for any loss or damage
resulting therefrom if due to circumstances beyond Landlord's control; but in
that event the commencement and termination dates of the Lease and all other
dates affected thereby shall be revised to conform to the date of Landlord's
delivery of possession. If the Premises are not Substantially Completed on or
before December 15, 1990, then, Tenant, at its election and in addition to its
other rights and remedies, shall be entitled to receive free rent equal to Ten
Thousand Dollars ($10,000) for each day beyond December 15, 1990 that the
Premises are not so Substantially Completed (the "Free Rent Amount"). Moreover
if the Premises are not Substantially Completed on or before July 15, 1991,
Tenant, at its election and in addition to its other remedies, shall have the
right to terminate this Lease and, at Tenant's election, any other lease between
Landlord and Tenant ("Other Lease") covering other space in the Project (the
"Other Space"). In the event Tenant elects to terminate this Lease as provided
herein, Landlord shall pay to Tenant the amount of the accrued Free Rent Amount
as of the date of termination.

               C. Tenant Delays: Notwithstanding the foregoing, if there is
an actual delay in Substantial Completion of the Premises as a result of "Tenant
Delays" (as that term is defined in the Construction Addendum), then the
foregoing dates on which Tenant is entitled to free rent and to terminate this
Lease or any Other Lease on account of Landlord's failure to Substantially
Complete the Premises shall be postponed one (1) day for each day of the actual
delay in Substantial Completion caused by the Tenant Delay. Further, the date
Tenant is otherwise obligated to commence paying rent shall occur one day sooner
for each day of such actual delay in Substantial Completion caused by the Tenant
Delay; provided, however, that the Commencement Date shall in no event be prior
to December 15, 1990 regardless of any Tenant Delay.

        8. ACCEPTANCE OF PREMISES AND COVENANTS TO SURRENDER:

               A. Punch List: As soon as Landlord reasonably believes that
the Premises are Substantially Completed, as defined in the Construction
Addendum, Landlord and Tenant shall together walk through and inspect the work
and prepare a written "punch list" of incomplete or defective construction.
Landlord shall use its best efforts to complete and/or repair any items on the
"punch list" within thirty (30) days after the parties have prepared the "punch
list" or as soon thereafter as practicable.

               B. Correction of Defects: Notwithstanding anything to the
contrary in the Lease, Tenant's acceptance of the Premises or submission of a
"punch list" shall not be deemed a waiver of Tenant's right to have construction
or design defects in the Interior Improvements and


                                      -4-
<PAGE>   10
the Premises repaired at Landlord's sole expense. Tenant shall give notice to
Landlord whenever any such defect becomes reasonably apparent, and Landlord
shall repair such defect as soon as practicable. Landlord also hereby assigns to
Tenant all warranties with respect to the Premises which would reduce Tenant's
maintenance obligations hereunder and shall cooperate with Tenant to enforce all
such warranties. Landlord warrants that it will obtain a two (2) year warranty
from its contractors and suppliers on the roof membrane and, without limiting
any other obligation of Landlord hereunder, Landlord shall correct any defect or
problem in the roof membrane (except for routine maintenance items as set forth
in paragraph 11) for a period of two (2) years after the Commencement Date.
Further, without limiting any obligation of Landlord under this Lease, Landlord
warrants that it will obtain an express one (1) year warranty from its
contractors and suppliers on all other items and will not waive the protection
of any statute or case law providing for a longer period to assert a claim for
defects in the Premises or any item therein.

               C. Surrender: Tenant agrees on the last day of the Lease
Term, or promptly following any sooner termination of this Lease, to surrender
the Premises to Landlord in the condition delivered to Tenant, reasonable wear
and tear, acts of God, casualties, condemnation, Hazardous Materials, as defined
in paragraph 18 hereof (other than those stored, used or disposed of by Tenant
in or about the Premises in violation of Law, as "Law" defined in paragraph
11(a)), and Alterations (as defined in paragraph 10) made by Tenant which
Landlord has not required Tenant to remove, excepted. Tenant shall ascertain
from Landlord within thirty (30) days before the expiration of the Lease Term or
promptly following any sooner termination whether Landlord will require Tenant
to remove any Alterations made by Tenant at the Premises; provided that Landlord
shall not require Tenant to remove any Alteration which Landlord has previously
indicated may remain at the Premises. If Landlord shall so require, then Tenant
shall remove such Alterations as Landlord may designate and shall repair any
damage to the Premises occasioned by the removal before the expiration of the
Lease Term or promptly following any earlier termination at Tenant's sole cost
and expense. On or before the end of the Lease Term or promptly following sooner
termination of the Lease Term, Tenant shall remove all of its personal property
and trade fixtures from the Premises, and all property not so removed shall be
deemed to be abandoned by Tenant.

        9. USES PROHIBITED: Tenant shall not commit, or suffer to be committed,
any waste or nuisance upon the Premises, or allow any sale by auction upon the
Premises, or allow the Premises to be used for any unlawful purpose, or place
any loads upon the floor, walls, or ceiling which endanger the structure, or use
any machinery or apparatus which will vibrate or shake the Premises or the
Building of which it is a part so as to damage the Premises other than ordinary
wear and tear or otherwise in violation of applicable Law, or place any harmful
liquids, waste materials, or Hazardous Materials in the drainage system of, or
upon or in the soils surrounding the Building so as to damage the Premises or
otherwise in violation of applicable Law. No materials, supplies, equipment,
finished products or semi-finished products, raw materials or articles of any
nature or any waste materials, refuse, scrap or debris shall be stored upon or
permitted to remain on any portion of the Premises outside of the Building
proper in violation of Law.


                                      -5-
<PAGE>   11
        10. ALTERATIONS AND ADDITIONS:

               A. Construction of Alterations: Tenant may construct
non-structural alterations, additions and improvements ("Alterations") in the
Premises without Landlord's prior approval, if the cost of such work does not
exceed Fifty Thousand Dollars ($50,000.00). In the event Tenant desires to make
Alterations costing more than Fifty Thousand Dollars ($50,000.00) or structural
Alterations, Landlord's consent shall not be unreasonably withheld and, if
Landlord does not notify Tenant in writing of its reasonable disapproval of such
Alteration within fourteen (14) days following Tenant's written request for
approval and delivery to Landlord of the proposed plans, then Landlord shall be
deemed to have approved the proposed Alteration. Upon the request of Tenant,
Landlord shall within the above-stated fourteen (14) day period advise Tenant in
writing as to whether Landlord shall require removal of any Alteration in
question upon the expiration or earlier termination of the Lease. After having
obtained Landlord's consent, Tenant agrees that it will not proceed to make
Alterations until three (3) days from the receipt (or deemed receipt) of such
consent, in order that Landlord may post appropriate notices to avoid any
liability to contractors or material suppliers for payment for Tenant's
Alterations. Tenant will at all times permit such notices to be posted and to
remain posted until the completion of work.

               B. Ownership of Alterations: All Alterations, trade fixtures
and personal property installed in the Premises at Tenant's expense ("Tenant's
Property") shall at all times remain Tenant's property and Tenant shall be
entitled to all depreciation, amortization and other tax benefits with respect
thereto. Except for Alterations which cannot be removed without structural
injury to the Premises, Tenant may remove Tenant's Property from the Premises at
any time, provided Tenant repairs any damage caused by such removal. Landlord
shall have no lien or other interest whatsoever in any item of Tenant's Property
located in the Premises or elsewhere, or any portion thereof or interest
therein, and Landlord hereby waives all such liens and interests. Within ten
(10) days following Tenant's request, Landlord shall execute documents in
reasonable form to evidence Landlord's waiver of any right, title, lien or
interest in Tenant's Property located in the Premises.

        11. MAINTENANCE OF PREMISES:

               A. Tenant Maintenance: Subject to Landlord's obligations as
set forth in this Lease, and the amortization of capital items as described
below, Tenant shall, at its sole cost, keep and maintain, repair and replace,
the Premises and appurtenances, including, but not limited to, interior non-load
bearing walls, the roof membrane, sidewalks, parking areas, plumbing, electrical
and HVAC systems, and all the Interior Improvements in good and sanitary order,
condition, and repair. Notwithstanding the foregoing, Landlord shall repair and
maintain, at its sole cost, the structural portions of the Premises at all times
during the Lease Term, including the foundation, exterior walls, load-bearing
walls, roof structure and windows. Tenant shall provide Landlord with a copy of
a service contract between Tenant and a licensed air-conditioning and heating
contractor which contract shall provide for maintenance of all air conditioning
and heating equipment at the Premises at such intervals as may be reasonably
required by the manufacturer of such equipment. Subject to the obligations of
Landlord hereunder and the


                                      -6-
<PAGE>   12
amortization of capital items as set forth below, Tenant shall pay the cost of
all air-conditioning and heating equipment repairs or replacements. Tenant shall
be responsible for the preventive maintenance of the membrane of the roof, which
responsibility shall be deemed properly discharged if: (i) Tenant contracts with
a licensed roof contractor who is reasonably satisfactory to both Tenant and
Landlord, at Tenant's sole cost, to inspect the roof membrane at least every six
months, with the first inspection due the sixth (6th) month after the
Commencement Date; and (ii) Tenant performs, at Tenant's sole cost, all routine
preventive maintenance recommendations made by such contractor within a
reasonable time after such recommendations are made. Such preventive maintenance
might include acts such as clearing storm gutters and drains, removing debris
from the roof membrane, trimming trees overhanging the roof membrane, applying
coating materials to seal roof penetrations, repairing blisters, and other
routine measures. Tenant shall provide to Landlord a copy of such preventive
maintenance contract and paid invoices for the recommended work for which Tenant
is responsible. Subject to Landlord's obligations hereunder and to the
amortization of capital items set forth below, Tenant agrees to water, maintain
and replace, when necessary, any shrubbery and landscaping.

               B. Excluded Costs: Notwithstanding anything to the contrary
in this Lease, in no event shall Tenant have any obligation to perform or to pay
directly, or to reimburse Landlord for, all or any portion of the following
repairs, maintenance, improvements, replacements, premiums, claims, losses,
fees, charges, costs and expenses (collectively "Costs") nor shall any portion
of the Interior Improvement Costs (as defined in the Construction Addendum)
consist of the following items, all of which shall be the responsibility of
Landlord:

                      (1) Losses Caused By Others: Costs occasioned by the act
or omission or violation of covenants, statutes, laws, orders, rules,
underwriter's requirement, regulations, private restrictions, building codes or
ordinances (collectively, "Laws"), misrepresentation, or breach of this Lease,
by Landlord or its agents, employees, contractors, subcontractors or tenants.

                      (2) Casualties and Condemnations: Costs occasioned by
fire, acts of God, or other casualties or by the exercise of the power of
eminent domain, provided that Tenant will pay insurance deductibles but only to
the extent expressly provided for in paragraph 12.D of this Lease.

                      (3) Reimbursable Expenses: Costs for which Landlord has a
right of reimbursement from others or for which Landlord actually receives
reimbursement.

                      (4) Construction Defects and Compliance with Law: Costs
(i) relating to a failure of the Premises to conform to all CC&Rs, underwriter's
requirements or Laws as of the Commencement Date; (ii) relating to construction
defects; and (iii) required to conform the Premises to the Building Plans as
defined in the Construction Addendum.

                      (5) Hazardous Materials: Except to the extent caused by
the disposal, release, emission or storage of the Hazardous Material in question
by Tenant, its agents, employees, invitees or contractors in violation of Law,
Costs incurred to investigate the presence of any Hazardous Materials, Costs to
respond to any claim of Hazardous Material contamination


                                      -7-
<PAGE>   13
or damage, Costs to remove any Hazardous Material from the Premises, judgments
or other Costs incurred in connection with any Hazardous Materials exposure or
releases, and any other Cost associated with a Hazardous Material.

                      (6) Capital Improvements: If Tenant's maintenance or
repair obligations as set forth in this Lease would require Tenant to perform or
pay for any item which would be properly be capitalized under generally accepted
accounting principles, and the cost of any such individual item exceeds Ten
Thousand Dollars ($10,000), then Tenant shall perform such repair or make such
replacement and the cost of such item or improvement shall be allocated as
follows. Landlord and Tenant shall establish the useful life of the item in
question based upon generally accepted accounting principles. Tenant shall pay a
proportion of the cost equal to the actual cost of such improvement or item
times a fraction, the numerator of which is the number of months remaining in
the initial Lease Term, and the denominator of which is the useful life of the
improvement in months. Landlord shall pay to Tenant the balance of such cost
within five (5) days after written demand by Tenant. For purposes hereof,
Tenant's remodeling of finishes (such as wallpaper or carpeting) shall not be
considered a capital item toward which Landlord shall be required to contribute.

                      (7) Parking Lot: Costs relating to the repaving or
resurfacing of the parking area if such repaving or resurfacing is required more
frequently than once every five (5) years.

        12. INSURANCE AND DEDUCTIBLES:

               A. Tenant's Use: Tenant shall not use, or permit any part of
the Premises, to be used for any unlawful purpose and no use shall be made or
permitted to be made of the Premises, nor acts done, which will cause an
increase in insurance premiums for the insurance to be maintained by Landlord
(unless Tenant agrees to pay for the cost of such increase) or a cancellation of
any insurance policy covering the Building. Tenant shall, at its sole cost and
expense, comply with any and all requirements, pertaining to the Premises, of
any insurance organization or company, necessary for the maintenance of
reasonable fire and public liability insurance covering the Building and
appurtenances, excluding structural improvements not related to Tenant's
specific and particular use.

               B. Landlord's Insurance: Landlord agrees to purchase and keep
in force fire and extended coverage insurance in so-called "all risk" form
covering the Premises and all of the Interior Improvements (as defined in the
Construction Addendum) paid for by Landlord in the amount of their full
replacement value. Tenant agrees to pay to the Landlord as additional rent, on
demand, the cost of said insurance as evidenced by insurance billings to
Landlord. Payment shall be due to Landlord on the later of: (i) thirty (30) days
after written invoice to Tenant; or (ii) twenty (20) days prior to the due date
of such premiums. Tenant's obligation under this paragraph will be prorate to
reflect the commencement and termination dates of this Lease. With respect to
earthquake insurance, Landlord agrees to purchase earthquake coverage and Tenant
agrees to reimburse Landlord for the additional cost of such insurance provided
such insurance is commercially available, and provided further: (i) Tenant
requests such coverage and agrees to


                                      -8-
<PAGE>   14
pay for the same; or (ii) such insurance is required by Landlord's lender and is
customarily required by institutional lenders on comparable buildings in Santa
Clara County, and in such case the premium for such earthquake coverage shall be
shared equally between Landlord and Tenant and payable by Tenant in the manner
set forth above for casualty insurance. If the Project is located in a flood
zone, Landlord shall also maintain flood insurance insuring the Building and
Interior Improvements paid for by Landlord for their full replacement value, and
Tenant shall pay for flood insurance premiums in the manner set forth herein,
unless Tenant indicates to Landlord in writing that Tenant does not elect for
Landlord to carry such coverage.

               C. Tenant's Insurance: Tenant agrees to insure its personal
property, Interior Improvements paid for by Tenant and Alterations for their
full replacement value and to obtain worker's compensation insurance as required
by Law. Tenant shall also maintain comprehensive general liability insurance for
occurrences within the Premises of $5,000,000.00 combined single limit for
bodily injury and property damage. Tenant shall name Landlord as an additional
insured under such comprehensive general liability policy, and shall deliver a
copy of such policy and renewal certificates to Landlord within thirty (30) days
after the Commencement Date. Tenant's comprehensive general liability policy
shall provide for thirty (30) days' prior written notice to Landlord of any
cancellation or termination.

               D. Insurance Deductibles: Tenant shall have the right to
specify the deductible of any insurance policy to be carried by Landlord under
this Lease and shall reimburse Landlord, in the manner set forth in subparagraph
12.B, for the premiums payable with respect to insurance policies for which
Tenant is responsible under subparagraph 12.B containing the deductible so
specified by Tenant or on insurance policies for which Tenant fails to specify a
deductible amount within thirty (30) days following Landlord's written demand
for such deductible specification. In the event of damage to the Premises
covered by Landlord's "all risk" casualty policy (and not caused by the
negligence or willful misconduct of Landlord or Landlord's employees, agents,
contractors or invitees), Tenant shall pay the amount of any deductible under
such policy if this Lease is not terminated in connection with such casualty as
provided in paragraph 28 hereof, provided Tenant has approved in writing in
advance the amount of such deductible. Tenant shall in no event be required to
pay for any flood or earthquake insurance deductibles; however, if flood or
earthquake deductibles (as approved or deemed approved by Tenant) exceed ten
percent (10%) of the replacement value of the Premises, in the event of a flood
or earthquake, such casualty shall be treated as an "Uninsured Casualty" under
paragraph 28 hereof.

               E. Waiver: Notwithstanding anything to the contrary in this
Lease, Landlord and Tenant hereby waive any rights each may have against the
other on account of any loss or damage that is caused or results from a risk
which is actually insured against, which is required to be insured against under
this Lease, or which would normally be covered by a standard form of full
replacement value "all risk extended coverage" casualty insurance, regardless of
whether such loss or damage is due to the negligence of Landlord or Tenant or of
their respective agents, employees, subtenants, contractors, assignees, invitees
or any other cause. Each party shall use its best efforts to obtain from their
respective insurance companies a waiver of any right of subrogation which said
insurance company may have against the Landlord or the Tenant, as the


                                      -9-
<PAGE>   15
case may be. If such insurance policy cannot be obtained with such waiver of
subrogation, or if such waiver of subrogation is only available at additional
cost and the party for whose benefit the waiver is not obtained does not pay
such additional cost, then the party obtaining such insurance shall immediately
notify the other party of that fact.

        13. TAXES:

               A. Payment of Taxes: Tenant shall be liable for all taxes
levied against Tenant's personal property and trade or business fixtures, and
agrees to pay, as additional rental, all real estate taxes and special
assessment installments levied on the Premises or upon the occupancy of the
Premises. Tenant shall pay such taxes on the later of: (i) twenty (20) days
after written notice from Landlord (which notice shall contain a copy of the tax
bill in question) or (ii) ten (10) days before the tax delinquency date. It is
understood and agreed that Tenant's obligation under this paragraph will be
prorated to reflect the commencement and termination dates of this Lease Term.
If at any time during the term of this Lease a tax, excise on rents, business
license tax, or any other tax, however described, is levied or assessed against
Landlord, as a substitute or addition in whole or in part for taxes described
herein, Tenant shall pay such tax within the time period set forth above. In the
event that a tax that is the obligation of Tenant to pay hereunder is placed,
levied, or assessed against Landlord and the taxing authority takes the position
that Tenant cannot pay and discharge the tax in question, then at the sole
election of Landlord, Landlord may increase the rental charged hereunder by the
exact amount of such tax. Notwithstanding anything to the contrary herein,
Tenant shall not be required to pay any portion of any tax or assessment: (i)
levied on Landlord's rental income, unless such tax or assessment is imposed in
lieu of real property taxes; (ii) in excess of the amount which would be payable
if such tax or assessment were paid in installments over the longest possible
term; (iii) imposed on land and improvements other than the Premises; (iv)
occasioned by a change of ownership or other conveyance of the Premises or any
interest in the Premises or Landlord except as otherwise set forth in
subparagraph 13.C below; or (v) attributable to Landlord's net income,
inheritance, gift, transfer, franchise or estate taxes. Tenant may in good faith
contest any real property taxes provided that it indemnifies Landlord from any
loss or liability in connection therewith.

               B. Assessments: Landlord represents and warrants to Tenant
that as of the date of this Lease and again as of the Commencement Date, the
only tax assessment that encumbers the Premises or Project is that certain
assessment levied under San Jose Assessment Number 23E-971-OLD and that in no
event shall Tenant's obligation to pay such assessment exceed (i) on the
average, more than Two and Five-Tenths Cents ($.025) per square of the Building
per month during the Lease Term; or (ii) more than Three and Two-Tenths Cents
($.032) per square foot of the Building per month during any month of the Lease
Term. If any other tax assessments exist with respect to the Premises or the
Project as of the date of this Lease or on the Commencement Date, or if the
amount of the foregoing assessment exceeds that set forth herein, Landlord shall
pay the amount of such assessment or excess, as the case may be, without
contribution by Tenant. Landlord represents that as of the date of this Lease,
Landlord is not aware of any pending future assessments affecting the Project.


                                      -10-
<PAGE>   16
               C. Change of Ownership: If property taxes increase as a
result of reassessment after change of ownership under Proposition 13 or any
successor Law, Tenant's liability for property taxes during each of the twelve
(12) month periods following the change of ownership, commencing as of the date
of the change of ownership, shall be limited as follows: Tenant's liability in
the first twelve (12) months following the transfer of ownership shall be
limited to one hundred thirty-three and one-third percent (133 1/3%) of the
property taxes payable hereunder by Tenant with respect to the twelve (12)
months paid immediately preceding the transfer, and in the second twelve (12)
month period one hundred sixty-six and two-thirds percent (166 2/3%) of the
property taxes paid by Tenant with respect to the twelve month period preceding
the transfer. Commencing on the second anniversary of the change in ownership,
Tenant shall be liable for the entire amount of property taxes for which Tenant
is otherwise responsible under this Lease levied against the Premises with
respect to each period after the second anniversary. If the reassessment occurs
as of a date other than July 1 (i.e. the commencement of a tax year), Tenant's
liability for property taxes shall be prorated on the basis of a 365-day year
for the purpose of calculating the amounts payable by Tenant during the two
years following the transfer.

        14. UTILITIES: Tenant shall pay directly to the providing utility for
all service charges pertaining to water, gas, heat, light, power, telephone and
other utilities supplied to the Premises. Landlord shall not be liable for a
loss of or injury to property, however occurring, through or in connection with
or incidental to furnishing or failure to furnish any of utilities to the
Premises and Tenant shall not be entitled to abatement or reduction of any
portion of the rent, so long as any failure to provide and furnish the utilities
to the Premises is due to a cause beyond Landlord's reasonable control.
Notwithstanding the foregoing, if utilities are not available to the Premises
for a period of fifteen (15) days or more and such failure does not result from
Tenant's failure to make the payments required herein, Tenant shall be entitled
to an abatement of rent to the extent of the interference with Tenant's use of
the Premises occasioned thereby. If such interference is not corrected so that
the Premises are reasonably suitable for Tenant's intended use within three
hundred sixty-five (365) days following the interference or interruption, then
Tenant shall be entitled to terminate this Lease and, at Tenant's election, any
Other Lease by delivery of written notice to Landlord.

        15. ABANDONMENT: Tenant shall not abandon the Premises at any time
during the term; and if Tenant shall abandon or surrender the Premises, or be
dispossessed by process of law, any personal property belonging to Tenant and
left on the Premises shall be deemed to be abandoned, at the option of Landlord.

        16. FREE FROM LIENS: Tenant shall keep the Premises and the property on
which the Premises are situated, free from any liens arising out of any work
performed, materials furnished, or obligations incurred by Tenant; provided,
however that if Tenant, in good faith, elects to contest such lien, Tenant shall
furnish a bond or other security reasonably acceptable to Landlord and Tenant
shall not then be deemed in default under this Lease.

        17. COMPLIANCE WITH GOVERNMENTAL REGULATIONS: Tenant shall, at its sole
cost and expense, comply with all of the requirements of all municipal, state
and


                                      -11-
<PAGE>   17
federal authorities now in force, or which may hereafter be in force, pertaining
to Tenant's particular and specific use of the Premises, and shall faithfully
observe in the use of the Premises all municipal ordinances and state and
federal statutes now in force or which may hereafter be in force. The judgment
of any court of competent jurisdiction, or the admission of Tenant or Landlord
in any action or proceeding, that Landlord or Tenant, as the case may be, has
violated any ordinance or statute, shall be conclusive of that fact as between
Landlord and Tenant. At the Commencement Date, the Premises shall conform to all
requirements of covenants, conditions, restrictions and encumbrances ("CC&Rs"),
all underwriters' requirements, and all Laws applicable thereto. Tenant shall
not be required to construct or pay the cost of complying with any CC&Rs,
underwriters' requirements or Laws requiring construction of improvements in the
Premises which are properly capitalized under generally accepted accounting
principles, unless such compliance is necessitated solely because of Tenant's
particular and specific use of the Premises. Any structural requirements or
Costs necessitated by CC&R's, underwriters' requirements or Laws which are
imposed on buildings or real estate generally (as opposed to the Premises
because of Tenant's specific and particular use) shall be performed or paid by
Landlord without reimbursement by Tenant.

        18. TOXIC WASTE AND ENVIRONMENTAL DAMAGE:

               A. Tenant's Responsibility: Tenant shall not bring, allow, or
use upon the Premises, or generate or create at or emit or dispose from the
Premises any chemicals, toxic or hazardous gaseous, liquid or solid materials or
waste, including without limitation, material or substance having
characteristics of ignitability, corrosivity, reactivity, or toxicity or
substances or materials which are listed on any of the Environmental Protection
Agency's lists of hazardous wastes or which are identified in Sections 66680
through 66685 of Title 22 of the California Administrative Code as the same may
be amended from time to time (which are referred to in this Lease as "Hazardous
Materials") in violation of Law. Tenant shall comply, at its sole cost, with all
Laws pertaining to, and shall indemnify and hold Landlord harmless from any
claims, liabilities, costs or expenses incurred or suffered by Landlord arising
from the bringing, using, generating, creating, or emitting or disposing of any
Hazardous Materials by Tenant. Tenant's indemnification and hold harmless
obligations as hereinbefore specified include, without limitation, (i) claims,
liability, costs or expenses resulting from or based upon administrative,
judicial (civil or criminal) or other action, legal or equitable, brought by any
private or public person under common law or under the Comprehensive
Environmental Response, compensation and Liability Act of 1980 ("CERCLA"), the
Resource Conservation and Recovery Act of 1980 ("RCRA") or any other Federal,
State, County or Municipal law, ordinance or regulation; (ii) claims,
liabilities, costs or expenses pertaining to the cleanup or containment of
wastes, the identification of the pollutants in the waste, the identification of
scope of any environmental contamination, the removal of pollutants from soils,
riverbeds or aquifers, the provision of an alternative public drinking water
source, or the long term monitoring of ground water and surface waters, all to
the extent required by applicable Law, and (iii) all costs of defending such
claims. Tenant further agrees to properly close the facility with regard to
Hazardous Materials and obtain a Closure Certificate from the local
administering agency for any Hazardous Material used, generated, emitted or
disposed of by Tenant in or about the Premises if so required by Law upon the
expiration or earlier termination of the Lease.

anything in this Lease, Tenant shall have no responsibility to Landlord,
Landlord's employees, contractors, officers, agents or partners or to any third
party for any Hazardous Material which was not released, stored, disposed of,
emitted, or discharged by Tenant, its agents, invitees, employees and
contractors in or about the Premises and which is or comes to be, present on or
about the Premises, or the soil or groundwater thereof, at any time. Landlord,
at its sole expense, shall promptly comply with all Laws, orders, injunctions,
judgments, mandates and directives of any applicable governmental authority
concerning the investigation, removal, monitoring or remediation of any
Hazardous Materials present on the Premises or the groundwater thereof, except
to the extent that the Hazardous Material in question was released, stored,
disposed of, emitted or discharged by Tenant or its employees, invitees, agents,
or contractors in or about the Premises. Landlord hereby waives all claims,
liabilities, costs, expenses or obligations, known or unknown, against Tenant
with respect to Hazardous Materials present on the Premises as of the
Commencement Date or which come to be present on the Premises after the
Commencement Date, except to the extent that the Hazardous Materials in question
were released, emitted, or discharged onto the Premises or Project by Tenant or
its employees, agents, contractors or invitees In this regard, Landlord
acknowledges that it is aware of and hereby waives the provisions of California
Civil Code Section 1542 (or any similar or successor Law) which provides as
follows:

               "A general release does not extend to claims which the creditor
               does not know or suspect to exist in his favor, at the time of
               executing the release, which if known by him must have materially
               affected the settlement with the debtor."

               C. Indemnity by Landlord: Landlord shall indemnify, defend
and hold harmless Tenant from all claims, losses, liabilities, fines, penalties,
damages, costs or expenses (including, without limitation, attorneys' and
consultants' fees and costs) arising out of or in connection with Hazardous
Material that come to be present at or about the Premises through the acts or
omissions of Landlord or its employees, tenants (including subtenants and
assignees), invitees, agents or contractors. Further, if Tenant terminates this
Lease in connection with or arising out of Hazardous Materials present at or
about the Premises or Project or the soil or groundwater thereof on the
Commencement Date, in addition to Landlord's other obligations hereunder,
Landlord shall be obligated to reimburse Tenant for the unamortized cost of the
Interior Improvements at the Premises paid for by Tenant. Further, Landlord
shall indemnify, defend and hold harmless Tenant from: (i) all costs and
expenses (including attorney's and consultants fees and costs) associated with
the investigation, removal, monitoring or remediation of Hazardous Materials not
released, stored, disposed of, emitted or discharged by Tenant, its agents,
employees, contractors or invitees in or about the Premises; and (iii) all
claims, liabilities or obligations (including, without limitation, any
attorneys' and consultants' fees incurred in connection with the same) by or to
any third party, including, without limitation, any governmental entity or body,
associated with Hazardous Materials present on the Premises or the soil or
groundwater thereof through no act of Tenant or Tenant's agents, employees,
contractors or invitees. The obligations of Landlord and Tenant hereunder shall
survive the expiration or earlier termination of the Lease Term.

               D. Representation by Landlord: Landlord hereby represents and
warrants to Tenant, except as outlined in the Levine Fricke report dated

operations conducted thereon prior to the Commencement Date are in compliance
with all Laws regarding Hazardous Materials ("Hazardous Materials Laws"), and
(ii) any handling, transportation, storage, treatment, disposal, release or use
of Hazardous Materials that has occurred on or about the Premises prior to the

Tenant acknowledges reviewing the correspondence dated March 1, 1990 from the
Department of Health Services concerning the "mixing" that occurred with respect
to DDT at the Project. Landlord further represents and warrants that no
litigation has been brought or threatened, nor any settlements reached with any
governmental or private party, concerning the actual or alleged presence of
Hazardous Materials on or about the Premises, nor has Landlord received any
notice of any violation, or any alleged violation of any Hazardous Materials
Laws, pending claims or pending investigations with respect to the presence of
Hazardous Materials on or about the Premises.

               E. Notification: Landlord and Tenant shall notify the other
of the existence of any reports, recommendations or studies prepared in
connection with any investigation for the presence of Hazardous Materials on or
about the Premises and shall give written notice to the other as soon as
reasonably practicable of (i) any communication received from any governmental
authority concerning any Hazardous Materials which relates to the Premises; and
(ii) any contamination of the Premises by Hazardous Materials which constitutes
a violation of any Hazardous Materials Laws.

               F. Environmental Studies: Tenant shall have the right, at
Tenant's expense, to conduct a baseline environmental study at the Project,
including the right to bore holes and take soils samples, if Tenant so elects,
provided Tenant obtains Landlord's advance written consent, which consent shall
not be unreasonably withheld.

        19. INDEMNITY: As a material part of the consideration to be rendered to
Landlord, Tenant hereby waives all claims against Landlord for damages to goods,
wares and merchandise, and all other personal property in, upon or about said
Premises and for injuries to persons in or about said Premises, from any cause
arising at any time, and Tenant will indemnify, defend and hold harmless
Landlord from any damage or injury to any person, or to the goods, wares and
merchandise and all other personal property of any person, arising from the use
of the Premises by Tenant, or from the failure of Tenant to keep the Premises in
good condition and repair, as herein provided. Further, in the event Landlord is
made party to any litigation due to the acts or omissions of Tenant, Tenant will
indemnify and hold Landlord harmless from any such claim or liability including
Landlord's costs and expenses and reasonable attorneys' fees incurred in
defending such claims except to the extent of the negligence or willful
misconduct of Landlord or its agents, employees or contractors or a breach of
this Lease by Landlord. Notwithstanding anything to the contrary in this Lease,
Tenant shall neither release Landlord from, nor indemnify, defend or hold
harmless Landlord with respect to: (i) the negligence or willful misconduct of
Landlord, or its agents, employees, tenants, contractors, subcontractors or
invitees; (ii) a breach of Landlord's obligations or representations under this
Lease; or (iii) any


                                      -14-
<PAGE>   20
Hazardous Material which was not released, emitted, or discharged by Tenant, its
agents, employees, invitees or contractors and which is or comes to be, present
on or about the Premises, or the soil or groundwater thereof, at any time.
Landlord shall indemnify, defend and hold Tenant harmless from any claim, loss,
expense, obligation damage or liability (including, without limitation, Tenant's
costs and expenses and reasonable attorney's fees) arising from or in connection
with: (i) the negligence or willful misconduct of Landlord or its employees,
agents, contractors or invitees; or (ii) a breach of Landlord's obligations or
representations under this Lease.

        20. ADVERTISEMENTS AND SIGNS: Tenant will not place or permit to be
placed, in, upon or about the said Premises unless such signs comply with all
Laws. Landlord agrees that Tenant may erect a monument sign or other signage on
the exterior of the Building that Tenant deems appropriate; provided, however,
that Tenant shall obtain Landlord's advance written approval of any signage
visible from the exterior of the Building, which consent shall not be
unreasonably withheld or delayed. Any sign so placed on the Premises shall be so
placed upon the understanding and agreement that Tenant will remove the same
before the expiration or promptly following any earlier termination of the Lease
Term and repair any damage or injury to the Premises caused thereby, and if not
so removed by Tenant then Landlord may have same so removed at Tenant's expense.
Landlord shall cooperate with and assist Tenant in acquiring permits for the
signage desired by Tenant; provided, however, that Landlord shall not be
required to incur additional out-of-pocket costs in connection therewith.

        21. ATTORNEY'S FEES: In case suit should be brought for the possession
of the Premises, for the recovery of any sum due hereunder, or because of the
breach of any other covenant herein, or in connection with any matter relating
to this Lease, the losing party shall pay to the prevailing party reasonable
attorneys' fees and court costs which shall be enforceable whether or not such
action is prosecuted to judgment.

        22. TENANT'S DEFAULT: The occurrence of any of the following shall
constitute a default under this Lease by Tenant: (a) any failure by Tenant to
pay the rental or to make any other payment required to be made by Tenant
hereunder, where such failure continues for ten (10) days after receipt by
Tenant of written notice of Landlord's failure to receive such payment; (b) the
abandonment of the Premises by Tenant; (c) failure by Tenant to observe and
perform any other provision of this Lease to be observed or performed by Tenant,
where such failure continues for thirty (30) days after written notice thereof
by Landlord to Tenant; provided, however, that if the nature of such failure is
such that the same cannot reasonably be cured within such thirty (30) day period
Tenant shall not be deemed to be in default if Tenant shall within such period
commence such cure and thereafter diligently prosecute the same to completion;
(d) the making by Tenant of any general assignment for the benefit of creditors;
the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt
or of a petition for reorganization or arrangement under any law relating to
bankruptcy (unless, in the case of a petition filed against Tenant, the same is
dismissed within sixty (60) days after the filing); the appointment of a trustee
or receiver to take possession of substantially all of Tenant's assets located
at the Premises or of Tenant's interest in this Lease, where possession is not
restored to Tenant within sixty (60) days; or the attachment, execution or other
judicial seizure of


                                      -15-
<PAGE>   21
substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where such seizure is not discharged within sixty (60)
days. The notice requirements set forth herein are in lieu of and not in
addition to the notices required by California Code of Civil Procedure Section
1161, provided that such notices are given in the manner required by such
statute.

               A. Remedies: In the event of any such default by Tenant, then
in addition to any other remedies available to Land-lord at law or in equity,
Landlord shall have the immediate option to terminate this Lease and all rights
of Tenant hereunder by giving written notice of such intention to terminate. In
the event that Landlord shall elect to so terminate this Lease then Landlord may
recover from Tenant: (a) the worth at the time of award of any unpaid rent which
had been earned at the time of such termination; plus (b) the worth at the time
of award of the amount by which the unpaid rent which would have been earned
after termination until the time of award exceeds the amount of such rental loss
Tenant proves could have been reasonably avoided; plus (c) the worth at the time
of award of the amount by which the unpaid rent for the balance of the term
after the time of award exceeds the amount of such rental loss that Tenant
proves could be reasonably avoided; plus (d) any other amount necessary to
compensate Landlord for all the detriment proximately caused by Tenant's failure
to perform its obligations under this Lease or which in the ordinary course of
things would be likely to result therefrom. The term "rent", as used herein,
shall be deemed to be and to mean the minimum monthly installments of rent and
all other sums required to be paid by Tenant pursuant to the terms of this
Lease, all other such sums being deemed to be additional rent due hereunder. As
used in (a) and (b) above, the "worth at the time of award" is computed by
allowing interest at the rate of the discount rate of the Federal Reserve Bank
of San Francisco plus five (5%) percent per annum. As used in (c) above, the
"worth at the time of award" is computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award
plus one (1%) percent.

               B. Right to Re-enter: In the event of any default by Tenant
that results in the termination of the Lease, Landlord shall also have the right
to re-enter the Premises and remove all persons and property from the Premises;
such property may be removed and stored in a public warehouse or elsewhere at
the cost of and for the account of Tenant.

               C. Abandonment: In the event of the abandonment of the
Premises by Tenant or in the event that Landlord shall elect to re-enter as
provided in Paragraph 22.B above or shall take possession of the Premises
pursuant to legal proceedings, then if Landlord does not elect to terminate this
Lease as provided in Paragraph 22.A above, then the provisions of California
Civil Code Section 1951.4, as amended from time to time, shall apply and
Landlord may from time to time, recover all rental as it becomes due.

               D. No Termination: No re-entry or taking possession of the
Premises by Landlord pursuant to 22.B or 22.C of this Article 22 shall be
construed as an election to terminate this Lease unless a written notice of such
intention be given to Tenant or unless the termination thereof be decreed by a
court of competent jurisdiction.


                                      -16-
<PAGE>   22
        23. SURRENDER OF LEASE: The voluntary or other surrender of this Lease
by Tenant, or a mutual cancellation thereof, shall not automatically effect a
merger of the Lease with Landlord's ownership of the Premises. Instead, at the
option of Landlord, Tenant's surrender may terminate all or any existing
sublease or subtenancies, or may operate as an assignment to Landlord of any or
all such subleases or subtenancies, thereby creating a direct relationship
between Landlord and any subtenants.

        24. RIGHT OF FIRST OFFER TO PURCHASE:

               A. Grant of First Right: Landlord hereby grants to Tenant a
right of first offer (the "Right of First Offer") to purchase the Project or any
portion thereof or interest therein. If Landlord proposes to sell or otherwise
transfer the Project, or any portion thereof, or interest therein, to a third
party, Landlord may do so only after first offering to sell the Project, or such
portion thereof or interest therein, as Landlord proposes to transfer to the
third party, to Tenant on the terms and conditions set forth in this paragraph.

               B. Term: The term of this Right of First Offer shall commence
on the date both parties have executed this Lease, and shall continue until the
expiration or earlier termination of the Lease in accordance with its terms.

               C. Notice of Intent to Sell: Landlord shall give written
notice of its intent to sell or transfer the Project or portion thereof to
Tenant ("Landlord's Notice"). The Landlord's Notice shall include a current
preliminary title report and the following "Basic Business Terms" upon which
Landlord is willing to sell the Premises: (i) the sales price and the terms upon
which such sales price is payable, (ii) the amount and terms of any seller
financing, (iii) the amount and terms of any assumable third party financing,
(iv) the state of title to be transferred by Landlord, (v) the date for close of
escrow, (vi) the proration of closing expenses, (vii) any Hazardous Materials
indemnities to be included in the purchase and sale agreement and (viii) any
other material business terms. A copy of any written offer to purchase the
Project by any third party shall be attached to Landlord's Notice.

               D. Exercise of Right of First Offer: Tenant may elect to
exercise its Right of First Offer by giving Landlord written notice of such
election on or before the tenth (10th) day following actual receipt of
Landlord's Notice.

               E. Terms of Sale: Upon Tenant's exercise of the Right of
First Offer, Landlord shall sell to Tenant the Project or portion thereof on the
Basic Business Terms stated in Landlord's Notice, except the purchase price to
be paid by Tenant shall be reduced by the brokerage commission contained in the
offer, if any. Tenant shall purchase the Project or portion thereof
substantially on the same terms and conditions stated in Landlord's Notice,
including without limitation any indemnities specified therein and on such other
terms as are reasonable and customary in comparable sales of comparable
properties in Santa Clara County to institutional buyers of or investors in real
property. The parties also shall execute a written sales agreement incorporating
the Basic Business Terms (as modified pursuant to this paragraph) and such other
reasonable and customary terms within twenty (20) days after the Tenant
exercises its


                                      -17-
<PAGE>   23
Right of First Offer; provided, however, that the failure of the parties to
execute a formal contract shall not affect Tenant's rights hereunder.

               F. Landlord's Right to Sell: If Tenant does not indicate in
writing its election to exercise its Right of First Offer within the allowed
time period, Landlord thereafter shall have the right to sell the portion of or
interest in the Project specified in Landlord's Notice to any third party;
provided (i) the sale is consummated on the same Basic Business Terms set forth
in Landlord's Notice, including, without limitation, at the same purchase price
and on terms no more favorable than those set forth in the Landlord's Notice;
and (ii) escrow for the sale closes on or before the one hundred eightieth
(180th) day following delivery of Landlord's Notice. Any sales transaction,
other than a sale complying with the foregoing, shall be deemed a new
determination by Landlord to sell the Project and no such sale may be
consummated, unless Tenant is first offered the right to purchase the Project in
accordance with the provisions of this Right of First Offer. The rights granted
by this paragraph 24 shall not apply to any exercise of private power of sale,
judicial foreclosure, deed in lieu of foreclosure or other proceedings to
enforce a mortgage or deed of trust encumbering the Project.

        25. LANDLORD'S DEFAULT: In the event of Landlord's failure to perform
any of its covenants or agreements under this Lease, Tenant shall give Landlord
written notice of such failure and shall give Landlord thirty (30) days or such
longer time as may be reasonably required by Landlord to cure said failure in
the exercise of reasonable diligence provided Landlord commences the cure within
said thirty (30) day period and thereafter diligently prosecutes such cure to
completion prior to pursuing its remedies on account of such default. If
Landlord so fails to perform its obligations under this Lease, then, in addition
to its other rights and remedies, Tenant shall have the right to cure Landlord's
default and (i) to recover from Landlord the cost of the cure together with
interest thereon at the prime rate charged by Union Bank, main San Francisco
branch, plus two percent (2%) per annum from the date of the expenditure until
the date of the repayment; or (ii) for the period during which Landlord or any
other individual or entity affiliated or related to Landlord owns the Project or
any portion thereof or interest therein, to deduct the cost of cure together
with interest thereon at the prime rate charged by Union Bank, main San
Francisco branch, plus two percent (2%) per annum from the date of the
expenditure from the sums otherwise payable by Tenant hereunder. Even if the
foregoing entities or individuals do not have an interest in the Project, Tenant
shall, in addition to Tenant's other rights or remedies, have the right to
deduct the cost of cure together with interest thereon at the above-stated rate,
provided that the total amount of such deduction shall not exceed One Hundred
Eleven Thousand Seven Hundred Dollars ($111,700.00).

        26. NOTICES: All notices required or permitted to be given by this Lease
shall be in writing and shall be personally delivered or delivered by reputable
commercial overnight courier to the parties at the following addresses, or such
other addresses as the parties shall designate by three (3) days' prior written

        27. ENTRY BY LANDLORD: Upon twenty-four (24) hours advance written
notice (except in the event of any emergency) and provided that Landlord does
not unreasonably interfere with Tenant's use of the Premises, Tenant shall
permit Landlord and its agents to enter upon said Premises at all reasonable
times subject to any security or safety regulations of Tenant for the purpose of
inspecting the same or for the purpose of maintaining the Premises or for the
purpose of making repairs or alterations of the Premises as may be required to
fulfill Landlord's obligations hereunder, without any rebate of rent or without
any liability to Tenant for any loss of occupation or quiet enjoyment of the
Premises thereby occasioned; and Tenant shall permit Landlord and his agents, at
any time within one hundred twenty (120) days prior to the expiration of this
Lease, to: (i) place upon said Premises any "For Sale" or "For Lease" signs
provided Landlord obtains Tenant's advance consent of the design and location of
such signs, which


                                      -19-
<PAGE>   25
consent by Tenant shall not be unreasonably withheld or delayed; and (ii)
exhibit the Premises to prospective tenants at reasonable hours upon reasonable
prior notice.

        28. DESTRUCTION OF PREMISES:

               A. Obligation to Restore: In the event of damage or
destruction to the Building or Premises or any portion thereof by any casualty
during the Lease Term, Landlord shall forthwith repair the same to the condition
the Building or Premises was in immediately before the destruction, provided
such casualty is of a type required to be insured against by Landlord under the
terms of this Lease or actually insured against by Landlord (herein collectively
referred to as an "Insured Casualty"). In the event of damage or destruction of
the Premises by a casualty of a type which is not required to be insured against
by Landlord under this Lease, and which is not actually insured against by
Landlord (herein referred to as an "Uninsured Casualty"), Landlord shall restore
the Premises to the same condition as they were in immediately before such
destruction and this Lease shall not terminate; provided, that if in the case of
such Uninsured Casualty the cost of restoration exceeds ten percent (10%) of the
then replacement value of the Building, Landlord may elect to terminate this
Lease by giving written notice to Tenant within fifteen (15) days after
determining the replacement value and furnishing reasonable evidence thereof to
Tenant. If Landlord so elects to terminate this Lease, Tenant, within fifteen
(15) days after receiving Landlord's notice to terminate, can elect to pay to
Landlord at the time Tenant notifies Landlord of its election, the difference
between ten percent (10%) of the replacement cost of the Premises and the actual
cost of restoration, in which case Landlord shall restore the Premises and this
Lease shall not terminate. If Landlord so elects to terminate this Lease and
Tenant does not elect to contribute the cost of restoration as provided herein,
this Lease shall terminate. In all events Landlord shall not be required to
restore Tenant's Alterations or replace Tenant's fixtures or personal property.
Tenant shall be entitled to a proportionate reduction of rent during the period
of damage and restoration, such proportionate reduction to be based upon the
extent to which the damage and making of repairs shall interfere with Tenant's
use of the Premises.

               B. Tenant's Right to Terminate: In the event of damage or
destruction either to the Premises or to any Other Space within the Project
leased by Tenant from Landlord, Landlord shall furnish to Tenant a good faith
written estimate from Landlord's architect or construction consultant of the
time period needed to restore the Premises or Other Space, as the case may be,
within thirty (30) days after the date of the damage or destruction in question.
If such estimate indicates that the repair or restoration of the Premises or
Other Space, as the case may be, cannot be made within three hundred sixty-five
(365) days after the date of damage or destruction, Tenant may, at its option,
terminate this Lease and, at Tenant's election, any Other Lease between Landlord
or Tenant by giving written notice to Landlord of such election within thirty
(30) days after receipt of Landlord's estimate. Tenant shall also have the right
to terminate this Lease and, at Tenant's election, any Other Lease if the actual
restoration of the Premises or Other Space, as the case may be, is not
effectuated within three hundred sixty-five (365) days after the date of the
casualty. Further, Tenant shall have the right to terminate this Lease if the
Building is damaged by any peril within twelve (12) months of the last day of
the Lease Term to such an extent that more than thirty percent (30%) of the
floor area of the Building is rendered


                                      -20-
<PAGE>   26
unusable by Tenant for a period of more than sixty (60) days. The provision of
Section 1932, Subdivision 2, and of Section 1933, Subdivision 4, of the Civil
Code of the State of California are waived by Tenant to the extent inconsistent
with the provisions of this Lease.

        29. ASSIGNMENT OR SUBLEASE:

               A. Permitted Transfers: Tenant may, without Landlord's prior
written consent and without any participation by Landlord in assignment or
subletting proceeds, sublet the Premises or assign the Lease to the following
(herein called "Permitted Transferees"): (i) a subsidiary, affiliate, division
or corporation controlled by or under common control with Tenant; (ii) a
successor corporation related to Tenant by merger, consolidation, or
non-bankruptcy reorganization; or (iii) a purchaser of substantially all of
Tenant's assets located in the Premises. For the purpose of this Lease, sale of
Tenant's capital stock shall not be deemed an assignment, subletting, or any
other transfer of the Lease or the Premises.

               B. Consent by Landlord: In the event Tenant desires to assign
this Lease or any interest therein including, without limitation, a pledge,
mortgage or other hypothecation, or sublet the Premises or any part thereof
except as set forth above with respect to Permitted Transferees, Tenant shall
deliver to Landlord copies of the proposed assignment or sublease, the financial
statements of the assignee or subtenant, and any additional information as
reasonably required by Landlord. Landlord shall then have a period of ten (10)
days following receipt of such notice within which to notify Tenant in writing
that Landlord elects (i) to permit Tenant to assign or sublet such space to the
named assignee/subtenant; or (ii) to refuse consent, provided Landlord shall not
unreasonably refuse such consent. If Landlord should fail to notify Tenant in
writing of such election within said ten (10) day period, Landlord shall be
deemed to have elected option (i) above. No assignment or subletting by Tenant
shall relieve Tenant of any obligation under this Lease. Landlord's consent to
the proposed assignment or sublease shall not be unreasonably withheld or
delayed, provided and upon the following conditions:

                      A. The proposed uses shall not violate Laws;

                      B. The proposed assignee or subtenant has sufficient
financial worth to undertake the responsibility involved under the assignment or
sublease, and Landlord has been furnished with reasonable proof thereof; and

                      C. Any proposed assignment shall be in form reasonably
satisfactory to Landlord.

               C. Assignment or Subletting Consideration: Any rent actually
received by Tenant under any such sublease or assignment in excess of the rent
payable hereunder, after deducting the unamortized cost of the Interior
Improvements paid by Tenant and Alterations installed at Tenant's expense, and
subletting and assignment costs incurred by Tenant in connection with the
assignment or sublease (including, without limitation, attorneys' fees,
brokerage commissions, and remodeling costs), any vacancy costs incurred by
Tenant, and Tenant's costs in performing under such assignment or sublease,
shall be paid by Tenant fifty


                                      -21-
<PAGE>   27
percent (50%) to Landlord. Tenant's obligation to pay such consideration shall
constitute an obligation for additional rent hereunder.

               D. No Release: Any assignment except to Permitted Transferees
shall be made only if and shall not be effective until the assignee shall
execute, acknowledge and deliver to Landlord an agreement, in form and substance
reasonably satisfactory to Landlord, whereby the assignee shall assume all of
the obligations of this Lease on the part of Tenant to be performed or observed
and shall be subject to all of the covenants, agreements, terms, provisions and
conditions contained in this Lease. Notwithstanding any such sublease or
assignment and the acceptance of rent or additional rent by Landlord from any
subtenant or assignee, Tenant shall and will remain fully liable for the payment
of the rent and additional rent due, and to become due hereunder, for the
performance of all of the covenants, agreements, terms, provisions and
conditions contained in this Lease on the part of Tenant to be performed and for
all acts and omissions of any licensee, subtenant, assignee or any other person
claiming under or through any subtenant that shall be in violation of any of the
obligations of this Lease, and any such violation shall be deemed to be a
violation by Tenant. Tenant shall further indemnify, defend and hold Landlord
harmless from and against any and all losses, liabilities, damages, costs and
expenses (including reasonable attorney fees) resulting from any claims that may
be made against Landlord by any real estate brokers or other persons claiming a
commission or similar compensation in connection with the proposed assignment or
sublease.

               E. Effect of Default: In the event of Tenant's default,
Tenant hereby assigns all rents due from any assignment or subletting to
Landlord as security for performance of its obligations under this Lease and
Landlord may collect such rents as Tenant's attorney-in-fact, except that Tenant
may collect and retain such rents unless a default occurs as described in
Paragraph 22 above. The termination of this Lease due to Tenant's default shall
not automatically terminate any assignment or sublease then in existence. At the
election of Landlord, the assignee or subtenant shall attorn to Landlord and
Landlord shall undertake the obligations of the Tenant under the sublease or
assignment; provided the Landlord shall not be liable for prepaid rent, security
deposits or other defaults of the Tenant to the subtenant or assignee.

        30. CONDEMNATION: If any part of the Premises, Other Space leased by
Tenant from Landlord, or the Project shall be taken for any public or
quasi-public use, under any statute or by right of eminent domain or private
purchase in lieu thereof, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall as to the part so taken, terminate as of
the date title shall vest in the condemnor or purchaser, and the rent payable
hereunder shall be adjusted so that Tenant shall be required to pay for the
remainder of the Lease Term only such portion of such rent as the value of the
part of the Premises remaining after such taking bears to the value of the
entire Premises prior to such taking; but in such event Tenant shall have the
option to terminate this Lease and, at Tenant's election, any Other Lease as of
the date when title to the part so taken vests in the condemnor or purchaser if
the taking or condemnation of the Premises, Other Space or Project is such that
the remaining space or Project unaffected by the condemnation or taking is not
reasonably suitable for Tenant's continued use or the conduct of Tenant's
business. If a part or all of the Premises be taken, all compensation awarded
upon such


                                      -22-
<PAGE>   28
taking shall go to the Landlord and the Tenant shall have no claim thereto;
provided, however, that nothing contained herein shall be deemed to waive or
release Tenant's interest in any award for (i) loss of or damage to Tenant's
trade fixtures, Alterations, or personal property; (ii) interruption of Tenant's
business; (iii) Tenant's loss of goodwill; (iv) Tenant's moving cost; (v)
Tenant's interest in any Interior Improvements; (vi) or any separate award made
to Tenant for whatever purpose. In the event that this Lease is not terminated
by reason of the condemnation, Landlord at its expense shall repair any damage
to the Premises caused by such condemnation. Tenant hereby waives the provisions
of California Code of Civil Procedures Section 1265.130 to the extent
inconsistent with the provisions of this Lease.

        31. EFFECTS OF CONVEYANCE: The term "Landlord" as used in this Lease,
means only the owner for the time being of the Premises, so that, in the event
of any sale of the Premises, the Landlord shall be and hereby is entirely freed
and relieved of all covenants and obligations of the Landlord hereunder accruing
after the date of the conveyance. Notwithstanding the foregoing, Landlord shall
not be relieved of its obligations under this Lease, unless and until Landlord
transfers the cash security deposit or original letter of credit to its
successor and the successor assumes in writing the obligations of Landlord
accruing on and after the effective date of the transfer. Furthermore, Landlord
shall not be relieved of its obligations hereunder accruing after the date of
the transfer unless the assignee or successor in question has the requisite net
worth to perform the obligations of Landlord hereunder, and Landlord furnishes
reasonable evidence thereof to Tenant.

        32. SUBORDINATION:

               A. Subordination to Future Obligations: If Landlord notifies
Tenant in writing, this Lease shall be subordinate to any ground Lease, deed of
trust, or other hypothecation for security now or hereafter placed upon the real
property of which the Premises are a part and to any and all advances made on
the security thereof and to renewals, modifications, replacements and extensions
thereof. Tenant agrees to promptly execute any reasonable documents which may be
required to effectuate such subordination. Notwithstanding such subordination,
Tenant's right to quiet possession of the Premises and other rights shall not be
disturbed if Tenant is not in default and so long as Tenant shall pay the rent
and observe and perform all of the provisions of this Lease. Notwithstanding
anything to the contrary in the Lease, subordination of Tenant's leasehold
interest to a mortgage, deed of trust, ground lease or instrument of security,
and Tenant's attornment to any party is conditioned upon (i) Tenant's concurrent
receipt from the lender or ground lessor in question of an express written
agreement in form reasonably satisfactory to Tenant providing for recognition of
all of the terms and conditions of this Lease and providing for continuation of
this Lease upon foreclosure of the deed of trust, mortgage or security interest
or termination of the ground lease; and (ii) the written agreement by such
successor to perform all of the obligations to be performed by Landlord under
the Lease on and after the date of the foreclosure or termination.

               B. Existing Obligations: Landlord represents and warrants
that the Project is not encumbered by a mortgage, deed of trust or ground lease
as of the date of both parties' execution of this Lease, except for a certain
loan in favor of Union Bank ("Union"). As a


                                      -23-
<PAGE>   29
condition precedent to Tenant's obligations under this lease or any Other Lease,
Landlord shall furnish to Tenant within fourteen (14) days of the date of both
parties' execution of this Lease with a written agreement in form satisfactory
to Tenant providing for: (i) recognition by Union of all of the terms and
conditions of this Lease and any Other Lease; and (ii) continuation of this
Lease and any Other Lease upon foreclosure of Union's security interest in the
Project.

        33. WAIVER: The waiver by Landlord or Tenant of any breach of any term,
covenant or condition, herein contained shall not be deemed to be a waiver of
such term, covenant or condition or any subsequent breach of the same or any
other term, covenant or condition herein contained. The subsequent acceptance of
rent hereunder by Landlord shall not be deemed to be a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, other than
the failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent.

        34. HOLDING OVER: Tenant shall have the right to hold ever under the
terms of this Lease for a period of up to eighteen (18) months by providing
Landlord written notice ("Holdover Notice") at least one hundred twenty (120)
days prior to the expiration of the Lease Term or extension thereof. Included in
the Notice shall be Tenant's determination of the holdover term required up to
eighteen (18) months. Rent during this period shall be at fair market rent as
defined in paragraph 38 below. Any holding over beyond the period elected in the
Notice, or after the Lease Term expires if no such Holdover Notice is given,
shall be construed to be a holdover tenancy and Tenant shall pay rent to
Landlord at a rate equal to one hundred twenty-five percent (125%) (prorated on
a daily basis) of the fair market rent as determined in accordance with
paragraph 38 for such period and shall otherwise be on the terms and conditions
herein specified. Furthermore, no holding over shall be deemed or construed to
exercise any option to extend or renew this Lease in lieu of full and timely
exercise of any such option as required hereunder. In establishing "fair market
rent" for purposes hereof, the parties (and the appraisers, if applicable) shall
take into account that Landlord shall not incur brokerage commissions, vacancy
costs, and costs for the installation of new interior improvements (including
recarpeting and repaving).

        35. SUCCESSORS AND ASSIGNS: The covenants and conditions herein
contained shall, subject to the provisions as to assignment, apply to and bind
the heirs, successors, executors, administrators and assigns of all the parties
hereto; and all of the parties hereto shall be jointly and severally liable
hereunder.

        36. ESTOPPEL CERTIFICATES: Each party shall at any time during the Lease
Term, upon not less than ten (10) business days prior written notice from the
other, execute and deliver to the requesting party a statement in writing
certifying that this Lease is unmodified and in full force and effect (or, if
modified, stating the nature of such modification) and the date to which the
rent and other charges are paid in advance, if any, and acknowledging that there
are not, to the party's knowledge, any uncured defaults on the part of the other
party hereunder or specifying such defaults if they are claimed. Any such
statement may be conclusively relied upon by any prospective purchaser or
encumbrancer of the Premises or a purchaser of Tenant's assets or leasehold
interest. Landlord's or Tenant's failure to deliver such statement within such


                                      -24-
<PAGE>   30
time shall be conclusive upon the party not providing the statement that: (a)
this Lease is in full force and effect, without modification except as may be
represented by the requesting party; (b) there are not uncured defaults in the
requesting party's performance.

        37. OPTION TO EXTEND: Tenant shall have the option and right to extend
the term of this Lease for three (3) separate additional and consecutive option
periods of five (5) years each (each such period being referred to as the
"Renewal Term") commencing with rent at ninety percent (90%) of the fair market
monthly rent only under the following conditions precedent: (i) that no material
event of default exists on the date of Tenant's exercise (i.e., Tenant has
failed to remedy any material breach in its performance within the time periods
set forth in paragraph 22); and (ii) Tenant has delivered written notice to
Landlord not less than one hundred and twenty (120) days prior to the expiration
of the then existing term of the Lease of Tenant's intention to extend the term
of the Lease. Tenant may exercise its option as to the premises whether or not
Tenant elects to exercise Tenant's option with respect to any Other Space. The
parties acknowledge that they have agreed to so set the rent at ninety percent
(90%) of the then fair market monthly rent for the premises in recognition of
and in consideration for, the fact that Landlord shall not incur brokerage
commissions, vacancy costs, and costs for the installation of new tenant
improvements (including recarpeting and repainting), along with other savings,
if Tenant elects to extend the term of this Lease, and that such discount of the
full fair market rent is a reasonable estimate of the savings to be so realized
by Landlord.

        38. APPRAISAL: If the parties are unable to agree upon the fair market
monthly rent for the Premises for the Renewal Term in question at least ninety
(90) days prior to the commencement of such Renewal Term, then the fair market
monthly rent shall be determined by appraisal conducted pursuant to this
paragraph 38. In the event it becomes necessary to determine by appraisal the
fair market rent for the Premises for the purpose of establishing the monthly
rent pursuant to paragraph 38 or for purposes of any other provision of this
Lease, then such fair market monthly rent shall be determined by three (3) real
estate appraisers, all of whom shall be members of the American Institute of
Real Estate Appraisers with not less than five (5) years experience appraising
commercial and industrial real property located in Santa Clara County,
California, in accordance with the following procedures:

               A. The party demanding an appraisal (the "Notifying Party")
shall notify the other party (the "Non-Notifying Party") thereof by delivering a
written demand for appraisal, which demand, to be effective, must give the name,
address and qualifications of an appraiser selected by the Notifying Party.
Within ten (10) days of receipt of said demand, the Non-Notifying Party shall
select its appraiser and notify the Notifying Party, in writing, of the name,
address and qualifications of an appraiser selected by it. Failure by the
Non-Notifying Party to select a qualified appraiser within said ten (10) day
period shall be deemed a waiver of its right to select a second appraiser on its
own behalf and the Notifying Party shall select a second appraiser on behalf of
the Non-Notifying Party within five (5) days after the expiration of said ten
(10) day period. Within ten (10) days from the date the second appraiser shall
have been appointed, the two (2) appraisers so selected shall appoint a third
appraiser. In the event the two appraisers fail to select a third qualified
appraiser, the third appraiser shall be appointed by the then Presiding


                                      -25-
<PAGE>   31
Judge of the Superior Court of the State of California for the County of Santa
Clara or the head of the most local chapter of the American Institute of Real
Estate Appraisers.

               B. The three (3) appraisers so selected shall meet in Santa
Clara County, California, not later than twenty (20) days following the
selection of the third appraiser. At said meeting the appraisers so selected
shall attempt to determine the fair market monthly rent of the Premises for the
Renewal Term in question.

               C. If the appraisers so selected are unable to complete their
determinations in one meeting, they may continue to consult at such times as
they deem necessary for a fifteen (15) day period from the date of the first
meeting, in an attempt to have at least two (2) of them agree. If at the initial
meeting or at any time during said fifteen (15) day period two (2) or more of
the appraisers so selected agree on the fair market rent for the Premises, such
agreement shall be determinative and binding on the parties hereto, and the
agreeing appraisers shall, in simple letter form executed by the agreeing
appraisers, forthwith notify both Landlord and Tenant of the amount set by such
agreement.

               D. In the event two (2) or more appraisers do not so agree
within said fifteen (15) day period, then each appraiser shall, within five (5)
days after the expiration of said fifteen (15) day period, submit his or her
independent appraisal in simple letter form to Landlord and Tenant stating his
or her determination of the fair market rent for the Premises for the Renewal
Term in question. The parties shall then determine the fair market rent for the
Premises by determining the average of the fair market rent set by each of the
appraisers; provided, however, that (i) if the lowest appraisal is less than
eighty-five percent (85%) of the middle appraisal, then such lowest appraisal
shall be disregarded; and/or (ii) if the highest appraisal is greater than one
hundred fifteen percent (115%) of the middle appraisal, then such highest
appraisal shall be disregarded. If any appraisal is so disregarded, then the
average shall be determined by computing the average set by the other appraisals
that have not been disregarded.

               E. Each party shall bear the fees and expenses of the
appraiser selected by or for it, and the fees and expenses of the third
appraiser (or the joint appraiser if one joint appraiser is used) shall be borne
fifty percent (50%) by Landlord and fifty percent (50%) by Tenant.

               F. Any determination of fair market rent of the Premises made
pursuant to any provision of this Lease, whether by agreement of the parties or
by appraisal pursuant to this paragraph, shall be based upon the following: (i)
that the Premises would be leased for five (5) years on the same terms as
contained in this Lease, particularly with regard to Tenant's obligation to pay
additional rent and its obligation to repair and maintain; (ii) the condition,
size, age and location of the Premises; and (iii) the fair market rent for the
Premises shall not include any part of the rental value added to the Premises as
a consequence of construction of Alterations or improvements made by Tenant or
at Tenant's expense.

               G. Tenant shall have the right to rescind its exercise of the
option if it does not approve in writing the fair market rent determined by
appraisal, but in such case, Tenant shall pay the costs of the appraisals. In
the event Tenant rescinds its exercise of the option, the Lease shall be
automatically extended for a period of one hundred twenty (120) days from the
date of


                                      -26-
<PAGE>   32
Tenant's written rescission at the rent then payable under this Lease until the
expiration of the Lease Term or Renewal Term in question, and thereafter at the
rate established by appraisal until the end of the one hundred twenty (120) day
period.

        39. COMMON AREA COSTS AND PARKING:

               A. Initial Occupancy: Landlord shall, subject to
reimbursement by Tenant as provided in Section 39(E) below, maintain in good
condition and repair all areas outside of the Building, except for any
landscaping located immediately adjacent to the Building, until Tenant occupies
all of the buildings in the Project.

               B. Subdivision: Promptly following Landlord and Tenant's
execution of this Lease, Landlord shall commence and use its best efforts to
effectuate a subdivision of the Project into three legal parcels complying with
the Subdivision Map Act and all Laws. Landlord shall obtain Tenant's advance
written approval of the boundaries of the proposed parcels and all material
aspects of the subdivision. Landlord shall pay all costs arising out of or in
connection with the subdivision. Furthermore, if Landlord becomes legally
required to subdivide the Project at any time during the Lease Term (for
example, if such subdivision is required by Law if the Project becomes a
multi-tenant Project), Landlord shall at its sole cost effectuate such
subdivision with Tenant's advance approval as indicated above.

               C. Common Area Costs: The parties acknowledge that if at any
time during the Lease Term Tenant no longer leases all of the buildings in the
Project, there will need to be an adjustment in the maintenance responsibilities
of the parties and a provision for the payment of costs pertaining to the
maintenance of those areas within the Project that are not designed for the
exclusive use of Tenant or other tenants such as the parking areas, sidewalks,
and landscaped areas (hereinafter "Common Area").

               D. Maintenance: If Tenant ceases to occupy all of the
buildings of the Project, Landlord shall be required to maintain the Common Area
and every part thereof in good and sanitary order, condition and repair.
Further, Landlord shall furnish utilities to such Common Areas.

               E. Payment of Common Area Costs: Tenant shall pay its
"Proportionate Share" of "Common Area Costs" as defined herein, within thirty
(30) days of written invoice from Landlord documenting such Common Area Costs.
Landlord shall not bill Tenant for such Common Area Costs more frequently than
once every three (3) months. For purposes hereof, the term "Common Area Costs"
shall mean the following:

                      (1) Service charges incurred by Landlord in furnishing
water and electricity to the Common Area; and

                      (2) The reasonable costs incurred by Landlord for routine
maintenance and repair of the Common Area, such as the reasonable costs paid by
Landlord to third party contractors for the routine maintenance of the
sidewalks, parking areas, driveways and landscaping.


                                      -27-
<PAGE>   33
               F. Proportionate Share: Tenant's "Proportionate Share" of
Common Area Costs shall be computed by multiplying the total Common Area Costs
by a fraction, the numerator of which is the square footage of the Building and
the denominator of which is the total square footage of all of the buildings in
the Project.

               G. Proration: It is understood and agreed that Tenant's
obligation to share in Common Area Costs shall be adjusted to reflect the
commencement and termination dates of the Lease Term.

               H. Parking: In the event Tenant does not occupy all of the
Project, Tenant shall be entitled to the non-exclusive use of a minimum number
of number of parking spaces equal to Tenant's Proportionate Share of all parking
spaces in the Project. Landlord agrees that in no event shall Landlord (i)
allocate exclusive parking spaces to any other tenant or occupant; (ii)
oversubscribe parking; or (iii) allocate to any other tenant or occupant more
than its proportionate share (based on the square footage occupied) of available
Project parking.

        40. QUIET ENJOYMENT: Tenant shall quietly have and hold the Premises for
the term and any extensions thereof subject to the provisions of this Lease
without interference by Landlord or any party claiming by or through Landlord.

        41. BROKERS/PREVIOUS DEALINGS: Landlord shall pay any commission due to
any broker, agent or finder claiming a fee or commission in connection with this
transaction without reimbursement by Tenant. Landlord shall indemnify, defend,
and hold Tenant harmless against any claim, cost, expense, liability, damage or
cause of action (including, without limitation, attorneys' fees and costs) in
connection with any claim or assertion by Coldwell Banker Commercial or any
party claiming through Coldwell Banker in connection with this Lease or any
Other Lease between Landlord or Tenant.

        42. AUTHORITY OF PARTIES:

               A. Authority of Tenant: This Lease and any Other Lease is
conditioned upon approval and ratification of this Lease and the Other Leases by
Tenant's Board of Directors pursuant to a duly adopted resolution of such Board
of Directors. If such approval pursuant to such resolution is not obtained on or
before May 25, 1990, this Lease and any Other Lease shall be of no force or
effect.

               B. Landlord's Authority: The individual(s) executing this
Lease on Landlord's behalf represent and warrant that they have the requisite
authority to sign this Lease and that this Lease is binding on Landlord.

        43. MISCELLANEOUS PROVISIONS:

               A. Rights and Remedies: All rights and remedies hereunder are
cumulative and not alternatives to the extent permitted by law and are in
addition to all other rights and remedies in law and in equity.


                                      -28-
<PAGE>   34

               B. Severability: If any term or provision of this Lease is
held unenforceable or invalid by a court of competent jurisdiction, the
remainder of the Lease shall not be invalidated thereby but shall be enforceable
in accordance with its terms, omitting the invalid or unenforceable term.

               C. Choice of Law: This Lease shall be governed by and construed
in accordance with California law.

               D. Interest: All sums due hereunder, including rent and
additional rent, if not paid within ten (10) days after written notice of the
delinquency, shall bear interest at the prime rate charged by Union Bank, main
San Francisco branch, plus two percent (2%) per annum from time to time or, if
lower, at the maximum rate permitted under California law accruing from the date
due until the date paid.

               E. Time: Time is of the essence hereunder.

               F. Headings: The headings or titles to the paragraphs of this
Lease are not a part of this Lease and shall have no effect upon the
construction or interpretation of any part thereof. This instrument contains all
of the agreements and conditions made between the parties hereto and may not be
modified orally or in any other manner than by an agreement in writing signed by
all of the parties hereto or their respective successors in interest.

               G. Performance by Landlord: If Tenant defaults in its
performance of any obligation required under this Lease after expiration of any
applicable cure period, Landlord, in its sole discretion, may, without further
notice, perform such obligation, in which event Tenant shall pay Landlord as
additional rent all reasonable sums paid by Landlord in connection with such
substitute performance within ten (10) days following Landlord's written notice
for such payment.

               H. Representations: Tenant acknowledges that, except as set
forth herein, neither Landlord or its affiliates or agents have made any
agreements, representations, warranties or promises with respect to the
Premises.

               I. Rent: All monetary sums due from Tenant to Landlord under this
Lease shall be deemed to be rent.

               J. Interference: If the Premises or any Other Space leased by
Tenant from Landlord should become unsuitable for Tenant's use as a consequence
of the presence of any Hazardous Material which does not result from Tenant's
use, storage or disposal of such material in violation of applicable Law or by
consequence of legal restrictions preventing Tenant's use of the Premises for
manufacturing and assembly ("Interfering Event"), which, in the case of the
foregoing Interfering Events persists for thirty (30) continuous business days,
then Tenant shall be entitled to an abatement of rent to the extent of the
interference with Tenant's use of the Premises or Other Space occasioned thereby
from the date of the Interfering Event, and, if such interference cannot be
corrected or the damage resulting therefrom repaired so that the Premises or any
Other Space leased by Tenant from Landlord will be reasonably suitable for
Tenant's


                                      -29-
<PAGE>   35
intended use within one hundred eighty (180) days following the occurrence of
the Interfering Event, then Tenant shall be entitled to terminate this Lease
and, at Tenant's election, any Other Lease by delivery of written notice to
Landlord at any time after occurrence of the Interfering Event.

               K. Approvals: Whenever the Lease requires an approval,
consent, designation, determination or judgment by either Landlord or Tenant,
such approval, consent, designation, determination or judgment (including,
without limiting the generality of the foregoing, those required in connection
with assignment and subletting) shall not be unreasonably withheld or delayed
and in exercising any right or remedy hereunder, each party shall at all times
act reasonably and in good faith.

               L. Reasonable Expenditures: Any expenditure by a party
permitted or required under the Lease, for which such party is entitled to
demand and does demand reimbursement from the other party, shall be limited to
the fair market value of the goods and services involved, shall be reasonably
incurred, and shall be substantiated by documentary evidence available for
inspection and review by the other party or its representative during normal
business hours.

               M. Exhibits: All exhibits are incorporated herein by reference.

               N. Light and View: Landlord shall not construct any structure
or improvement or do any other act that will impede Tenant's light, air or view.

               O. Memorandum of Lease: At Tenant's option, a memorandum of
this Lease shall be recorded in a form acceptable to Tenant in the Official
Records of Santa Clara County, California. Landlord agrees to execute such
memorandum.

LANDLORD:                                         TENANT:
John Michael Sobrato, or his Successor Trustee    PYRAMID TECHNOLOGY CORPORATION, a Delaware
Under Revocable Trust Agreement dated April 28,   corporation

        2. PLANS:

               A. Preliminary Plans For Interior Improvements: On or before
July 25, 1990, Tenant shall attempt to cause to be prepared and delivered to
Landlord a preliminary space plan for the Interior Improvements for Landlord's
approval, which approval shall not be unreasonably withheld. If Landlord fails
to approve or disapprove the proposed space plan within seven (7) days following
delivery of the proposed plan to Landlord, the space plan proposed by Tenant
shall be deemed to be the approved Preliminary Interior Improvement Plans for
the purposes of this Addendum. If Landlord disapproves the proposed space plan
in any respect, it shall deliver to Tenant its written proposal for required
changes and the parties shall negotiate in good faith to reach agreement on the
Preliminary Interior Improvement Plans. At Tenant's request, Landlord shall
confer with Tenant to obtain a preliminary cost estimate based upon the
Preliminary Interior Improvement Plans. Tenant shall have no obligation to
submit a preliminary space plan to Landlord, and if Tenant so elects, Tenant may
eliminate such intermediate procedure and proceed with the preparation of final
plans and specifications and working drawings in accordance with the procedures
set forth below.

               B. Final Interior Improvement Plans and Cost Estimate: On the
later of (i) that date that is fourteen (14) days after approval by both parties
of the Preliminary Interior Improvement Plans if Tenant elects to submit a
preliminary space plan to Landlord, or (ii) August 15, 1990, Tenant shall cause
the Interior Improvement Architect selected by Tenant and approved by Landlord
to prepare and deliver to Landlord proposed final plans, specifications and
working drawings for the Interior Improvements. Landlord shall submit any
reasonable objections to the proposed final plans, specifications and working
drawings to Tenant in writing within seven (7) days after Landlord's receipt of
same and shall submit a proposed Interior Improvement Cost Estimate for the
Interior Improvements shown on the proposed final plans, specifications and
working drawings, as amended by the changes reasonably made by Landlord. If
Tenant disapproves the cost estimate or the proposed final plans with Landlord's
modifications in any respect, then within seven (7) days following receipt of
the proposed final plans and cost estimate, Tenant may deliver to Landlord its
written proposal for the changes necessary, in Tenant's opinion, to satisfy
Tenant's objections or to reduce costs. If Tenant fails to approve or disapprove
the final plans within the allowed time period, the final plans proposed by
Tenant, with Landlord's reasonable modifications, shall be deemed to be the
approved Final Interior


                                      -4-
<PAGE>   41
Improvement Plans for the purpose of this Addendum. If Tenant fails to approve
or disapprove the proposed cost estimate within the allowed time period, the
cost estimate proposed by Landlord shall be deemed to be the approved Interior
Improvement Cost Estimate for the purposes of this Addendum. If Tenant proposes
changes to the proposed final plans for the Interior Improvements, Landlord
shall not unreasonably withhold its approval of such change and the parties
shall confer and negotiate in good faith to reach agreement on specific required
modifications to the proposed final plans and costs estimate as a consequence of
such change. If Tenant believes that the cost estimate is incorrect, it may
require that all or any portion of the work be submitted for competitive bids.
The final plans, modified for changes proposed by Tenant and approved by
Landlord pursuant to this paragraph, shall be the approved Final Interior
Improvement Plans and cost estimate approved by Tenant shall be the Interior
Improvement Cost Estimate for the purposes of this Addendum.

               C. Application For Approvals: As soon as the Final Interior
Improvement Plans are approved by Landlord and Tenant, Landlord shall submit the
approved Building Plans to all appropriate governmental agencies for their
approval and issuance of all required permits. Landlord shall use its best
efforts to obtain all governmental approvals and permits necessary for
construction of the Premises in accordance with the Building Plans on or before
October 15, 1990. Landlord and Tenant shall initial the Building Plans
immediately after all governmental approvals and permits have been obtained and
shall append the approved Building Plans and Interior Improvement Cost Estimate
to this Construction Addendum as Schedule 2.

               D. Termination: If all permits required for construction of
the Premises in accordance with the Building Plans have not been issued on or
before January 15, 1991, then Tenant, in its discretion, may elect to terminate
the Lease and, at Tenant's election, any Other Lease between Landlord and
Tenant.

               E. Changes to Building Plans: After the Building Plans have
been approved by Landlord and Tenant as provided above, neither party shall have
the right to require extra work or make any modifications with respect to the
construction of the Premises, without the prior written consent of the other
party as to (i) the change, (ii) any estimated delay in the scheduled completion
date of the Premises caused by the change, and (iii) any modification to the
Interior Improvement Cost Estimate as a consequence of the change. Landlord
shall not unreasonably withhold or delay its consent to changes or extra work
proposed by Tenant with respect to the Interior Improvements and, if the change
will not materially increase the cost incurred by Landlord for construction of
the Building Shell nor materially modify the exterior appearance of the Building
Shell, then Landlord also shall not unreasonably withhold its consent to change
in the Building Shell. Tenant shall not unreasonably withhold or delay its
consent to changes or extra work proposed by Landlord with respect to the
Building Shell which does not cause any modification of the Final Interior
Improvement Plans, does not increase Interior Improvement Costs, does not delay
construction and does not adversely impact the appearance of the Premise or
Tenant's proposed use. Tenant may withhold its consent, in its discretion, to
any change in the Final Interior Improvement Plans or Interior Improvement Cost
Estimate.

        3. CONTRACTORS:

               A. General Contractor: Landlord shall serve as the general
contractor for construction of the Interior Improvements.

               B. Subcontracts: Landlord shall cause each subcontract to be
competitively bid by three contractors for construction of the Interior
Improvements. The contractors to whom such work shall be competitively bid shall
be selected by Landlord and approved by Tenant, which approval shall not be
unreasonably withheld. All bids shall be opened simultaneously. All work shall
be awarded based upon the lowest bid submitted unless agreed in writing by
Tenant. Notwithstanding the foregoing, Tenant in its discretion may elect to use
Therma as the mechanical subcontractor and Viking Electric ("Viking") as the
electrical subcontractor in lieu of awarding such subcontracts on the basis of
competitive bids, or Tenant may require that Therma and Viking be one of the
contractors to whom such work shall be competitively bid. Notwithstanding
Tenant's right to approve the subcontractors, each subcontractor is a contractor
only of Landlord and Tenant shall have no liability to the subcontractor under
any subcontract or otherwise with respect to the Building.

               C. Construction Manager: Tenant shall have the right to elect
one of the following alternatives in Tenant's discretion: (i) to increase the
development fee set forth in subparagraph 1.L from seven percent (7%) to eight
percent (8%) in lieu of employing a construction manager; or (ii) employ a
construction manager to assist Tenant in planning its Interior Improvements or
to act in a supervisory role to evaluate Tenant's plans and requirements. In the
event Tenant elects to employ a construction manager Landlord shall submit to
Tenant a list of three construction managers to be employed by Tenant and Tenant
shall enter into a contract with one of such construction managers on terms
acceptable to Tenant. The fee charged by such construction manager shall at
Tenant's election be an "Interior Improvement Cost," and Landlord shall pay any
such fee before it becomes due under the terms of Tenant's contract. Landlord
shall not charge any development fee as set forth in subparagraph l.L on any
fees or charges by such construction manager. If Landlord fails to pay such
costs, Tenant, in addition to its other remedies, may (but shall not be
obligated to) advance such costs on Landlord's behalf, and Tenant shall be
entitled to recover such costs from Landlord together with interest at the rate
specified under paragraph 43.D of the Lease from the date of the expenditure
until repaid.

        4. COMMENCEMENT AND COMPLETION OF BUILDING:

               A. Landlord's Obligation To Construct The Building: As soon
as the Building Plans have been approved, all necessary governmental approvals
and permits have been obtained, and the bids have been accepted, Landlord shall
cause construction of the Building Shell and the Interior Improvements to be
commenced and diligently prosecuted to completion, so that the Premises will be
Substantially Complete as soon as possible. Landlord shall use its best efforts
to give Tenant partial occupancy of the portion of the Premises selected by
Tenant at the earliest possible date, if Tenant so chooses and if such partial
occupancy is legally


                                      -6-
<PAGE>   43
permissible and such partial occupancy shall not unreasonably interfere with
Landlord's completion of construction.

               B. Schedule of Critical Dates: Set forth in this paragraph is
a schedule of certain critical dates relating to Landlord's and Tenant's
respective obligations regarding the construction of the Building Shell and the
Interior Improvements (the "Schedule of Performance"). Landlord and Tenant shall
each be obligated to use reasonable efforts to perform their respective
obligations within the time periods set forth in this Schedule of Performance
and elsewhere in this Construction Addendum. The Schedule of Performance is as
follows:

</TABLE>

               C. Delivery of Possession: When the Premises are
substantially Complete, Landlord shall deliver possession of the Premises to
Tenant. However, Tenant shall have no obligation to accept possession of the
Premises or commence payment of rent until the Commencement Date, as defined in
paragraph 7 of the Lease.

               D. Failure to Deliver: Landlord hereby acknowledges that its
failure to deliver to Tenant Premises that are Substantially Complete on or
before December 15, 1990 will cause Tenant to incur costs not contemplated by
the Lease, the exact amount of which will be extremely difficult to ascertain.
Accordingly, if Landlord fails to deliver to Tenant Premises that are
Substantially Complete on or before said date, in Tenant's discretion, Tenant
shall be entitled to apply the sum designated in paragraph 7 of the Lease as the
"Free Rent Amount," to its rental obligations under the Lease. Further, if
Tenant elects to terminate this Lease as a result of Landlord's failure to
deliver possession of the Premises as provided for in the Lease or this
Addendum, Tenant shall be entitled to receive any accrued Free Rent Amount as of
the date of Tenant's termination as liquidated damages for each day delivery of
the Building is delayed beyond December 15, 1990. The parties hereby agree that
such amount represents a fair and reasonable estimate of the cost Tenant will
incur by reason of the late delivery of the Building. Acceptance by Tenant of
liquidated damages for delay shall not constitute a waiver of Landlord's breach
of any provision of the Lease.

        5. PAYMENT OF CONSTRUCTION COSTS:

               A. Tenant's Contribution To Interior Improvement Costs:
Tenant's obligation to pay the cost of constructing the Premises shall be
limited to the positive difference, if any, between the total Interior
Improvement Costs (not to exceed the Interior Improvement Cost Estimate approved
by Tenant in writing) and the Interior Improvement Allowance (or the sum of the
Interior Improvement Allowance and the portion of the Additional Interior
Improvement Allowance that Tenant elects to apply). The parties acknowledge that
Tenant shall have no obligation to pay any cost of constructing any portion of
the Premises in excess of such amount. If the Interior Improvement Cost Estimate
is more than the Interior Improvement Allowance (plus the portion of the
Additional Interior Improvement Allowance that Tenant elects to apply), Tenant
shall pay to Landlord a proportionate share of each progress payment due to the
subcontractors which bears the same relationship to the total amount of the

Costs bears to the Interior Improvement Cost Estimate. Tenant shall pay Tenant's
share of any progress payment to Landlord within fifteen (15) days after receipt
of a statement and reasonable documentation of such costs from Landlord. If
Tenant pays any such excess Interior Improvement Costs, as soon as possible
after commencement of the Lease, Landlord and Tenant shall designate as Tenant's
property Interior Improvements having a cost approximately equal to the excess
paid by Tenant. Property designated as Tenant's property under the terms of this
paragraph may be removed from the Premises at any time by Tenant and Tenant
shall be entitled to all investment tax credit, depreciation, and other tax
attributes relating to such property. In determining which Interior Improvements
will be designated as Tenant's property, the parties shall confer in good faith
and shall give preference to those Interior Improvements which are most readily
removable from the Building and which shall have the greatest utility for Tenant
outside of the Building but which are not required for basic business operations
at the Building. At the expiration or sooner termination of the Lease, all
Interior Improvements not designated as Tenant's property under this paragraph
shall be surrendered to Landlord in accordance with the terms of the Lease.

               B. Rights if Allowance Unused: If the Interior Improvement
Cost Estimate is less than Landlord's Interior Improvements Allowance, Tenant
shall be entitled to, at Tenant's election: (i) apply any unused allowance for
the payment of interior improvement costs for any other building leased by
Tenant from Landlord; or (ii) offset from its rental obligations under this
Lease the total amount of such unused Interior Improvement Allowance.

        6. TENANT'S RIGHT TO ENTER: Tenant, and its authorized representatives,
shall have the right to enter the Building at all reasonable times for the
purpose of inspecting the progress of the construction of the Building Shell and
Interior Improvements. Landlord shall give Tenant at least sixty (60) days prior
written notice of its estimated date for Substantial Completion of the Building,
so that Tenant may cause its fixtures and equipment to be ordered. When the
construction of the Building has proceeded to the point where Tenant's work of
installing its fixtures and equipment in the Building can be commenced in
accordance with good construction practice, Landlord also shall notify Tenant to
that effect and shall permit Tenant and its authorized representatives and
contractors to have access to the Building for a period of not less than thirty
(30) days for the purpose of installing Tenant's trade fixtures and equipment.

        7. CONSTRUCTION WARRANTY FOR THE BUILDING: Notwithstanding anything to
the contrary in the Lease, effective upon delivery of the Premises to Tenant,
Landlord does hereby warrant (i) that the Building Shell and the Interior
Improvements were constructed in accordance with any applicable covenants,
conditions or restrictions and the rules, regulations, codes, statutes,
ordinances, and laws of all governmental and quasi-governmental authorities
having jurisdiction over the Building, (ii) that the Building Shell and Interior
Improvements were constructed in accordance with the Building Plans and in a
good and workmanlike manner; and (iii) that all material and equipment installed
at the Premises conformed to the Building Plans and was new and otherwise of
good quality. Notwithstanding anything to the contrary contained in the Lease or
this Addendum, Tenant's acceptance of the Premises shall not be deemed a waiver
of the foregoing warranty or any other warranty of


                                      -9-
<PAGE>   46
Landlord under the Lease, and Landlord shall promptly repair all violations of
the warranty set forth in this paragraph at its sole cost and expense.

        8. RISK OF LOSS: Risk of loss of the Premises prior to the Commencement
Date of the Lease shall be borne by Landlord. At all times prior to the
Commencement Date, Landlord at its sole cost and expense shall maintain
so-called contingent liability and broad form "builder's risk" insurance with
coverage in an amount equal to the replacement cost of the Building Shell plus
the Interior Improvement Cost Estimate. The insurance policy (i) shall be in a
form reasonably satisfactory to Tenant, (ii) shall be carried with a company
reasonably acceptable to Tenant, (iii) shall provide that such policy shall not
be subject to cancellation or change except after at least ten (10) days prior
written notice to Tenant, and (iv) shall contain a "cross liability" provision
insuring Landlord and Tenant against any loss caused by the negligence of the
other party. If the Interior Improvement Cost Estimate exceeds the Interior
Improvement Allowance, Tenant shall be designated as a named insured on said
insurance policy and the "deductible" thereunder shall not exceed Five Thousand
Dollars ($5,000). If the Building is damaged or destroyed prior to the
Commencement of the Lease, Tenant shall have the right to terminate the Lease,
and, at Tenant's election, any Other Lease, if the Premises, in the reasonable
opinion of the Architect, cannot be Substantially Complete prior to September
15, 1991. If the Lease is so terminated, Tenant shall be entitled to that amount
of the builder's risk insurance proceeds equal to the amount, if any, paid by
Tenant for construction of the Interior Improvements prior to the termination
date. If the Premises are damaged or destroyed and the Lease is not terminated
pursuant to the terms of the Lease or this Addendum, Landlord shall promptly and
diligently complete construction of the Building in accordance with this
Addendum and all insurance proceeds with respect to the loss shall be paid to an
independent depository, reasonably acceptable to Landlord and Tenant, for
disbursement to the contractors completing the Building as the work progresses
in accordance with customary institutional lending practices.

        9. RIGHTS UPON TERMINATION: If the Lease is terminated pursuant to any
provision of this Addendum, then in addition to all other amounts due Tenant
hereunder, all security deposits, letters of credit, prepaid rent, and other
monies paid by Tenant under the terms of the Lease or this Addendum shall be
returned to Tenant upon demand. Subject to Tenant's rights under paragraph 8, in
the event Tenant elects to terminate this Lease, Landlord shall not be required
to return progress payments made by Tenant for construction of the Interior
Improvements in accordance with paragraph 5 of this Addendum.

        10. ACCOUNTING: Landlord shall submit to Tenant on a monthly basis an
accounting of all Interior Improvement Costs, certified as true and correct by
Landlord. Tenant shall have the right to audit the books, records and supporting
documents of Landlord during normal business hours, after giving Landlord at
least twenty-four (24) hours prior notice to the extent reasonably necessary to
determine the accuracy of any accounting. Within fifteen (15) days after
Substantial Completion, Landlord shall render to Tenant a final and detailed
accounting of all Interior Improvement Costs paid by Landlord and Tenant,
certified as true and correct by Landlord. Tenant shall have the same audit
rights as set forth above with respect to the monthly accountings. If such audit
discloses that an overpayment was made by Tenant, there


                                      -10-
<PAGE>   47
shall be an adjustment between Landlord and Tenant as soon as reasonably
practicable such that each shall only be required to contribute to the payment
of costs to the extent provided for in this Addendum.

        11. TENANT DELAYS: For purposes of this Construction Addendum and the
Lease, the foregoing shall be deemed "Tenant Delays": (i) Tenant's failure to
submit plans and information or review and approve information including the
Interior Improvement Cost Estimate by the dates set forth in this Construction
Addendum except that Tenant's failure to submit a preliminary space plan shall
not be deemed a "Tenant Delay" hereunder; or (ii) as a result of written change
orders made by Tenant pursuant to the terms of this Construction Addendum after
final approval of the Building Plans, to the extent specified in any written
change order. In the event of such Tenant Delays, then the dates on which Tenant
is entitled to the rent or other liquidated damages and to terminate this Lease
or any Other Lease on account of Landlord's failure to Substantially Complete
the Premises shall be postponed one day for each day of such actual delay in
Substantial Completion caused by such Tenant Delay. Furthermore, the date Tenant
is otherwise obligated to begin paying rent shall occur one day earlier than the
Commencement Date for each day that the Commencement Date is actually delayed as
a result of a Tenant Delay; provided, however, that for purposes of this
paragraph, the Commencement Date shall in no event be deemed to occur any date
earlier than December 15, 1990 regardless of any Tenant Delay.

        12. CONFLICT: In the event of any conflict between the terms of this
Addendum and the Lease, this Addendum shall prevail.

his Successor Trustee Under Revocable Trust Agreement dated April 28, 1989, as
amended, FBO Ann Sobrato, John A. Sobrato, Trustee Under Trust Agreement dated

square feet, located in San Jose, California, as such premises are more
particularly described in the Lease (the "Lease")

         B. The parties wish to clarify certain matters concerning the Lease in
this Amendment.

         NOW THEREFORE, in consideration of the mutual promises contained herein
and for other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties do hereby agree as follows:


                                    AGREEMENT

                               SUBLEASE AGREEMENT

        This Sublease Agreement ("Sublease") dated for reference purposes only,
December 15, 1997, by and between Siemens Pyramid Information Systems, Inc., a
Delaware corporation, with its principal offices at 3860 North First Street, San
Jose, California, 95134 ("SUBLANDLORD"), and Netro Corporation, a California

                                    RECITALS


                                  [ILLEGIBLE]


        Therefore, SUBLANDLORD and SUBTENANT agree as follows:

        1. PREMISES. Subject to the terms, conditions, and covenants set forth
in this Sublease, SUBLANDLORD hereby leases to SUBTENANT and SUBTENANT hereby
leases from SUBLANDLORD, approximately 47,950 rentable square foot in the

("Expansion Premises") at which time, the



<PAGE>   2

SUBLANDLORD shall deliver the Expansion Premises to SUBTENANT "broom clean" with
all building systems in good working and operable condition. The Expansion
Premises shown as outlined in green on Exhibit B. SUBTENANT shall have a right
of first refusal for the remainder of the Building commonly known as 3860 North
First Street, San Jose, CA-R3 under the same terms and conditions of this
Sublease Agreement, except as provided in this paragraph below.

        SUBTENANT shall have a right of first refusal to sublease the remainder
of the Building. If SUBLANDLORD desires to sublease that space, or any portion
thereof, to a third party, SUBLANDLORD shall provide written notice to SUBTENANT
of the terms upon which SUBLANDLORD would be willing to lease the space in
question. If SUBTENANT does not deliver written notice to SUBLANDLORD, within
fifteen (15) days of receipt of SUBLANDLORD's notice, of SUBTENANT's willingness
to occupy the subject space SUBLANDLORD shall be free to sublease that space to
the third party in question. If SUBTENANT does timely indicate its willingness
to occupy the subject space, SUBLANDLORD shall lease the space to SUBTENANT on
all the same terms and conditions set forth herein, including Rent, provided
that if SUBTENANT indicates in its response to SUBLANDLORD that SUBTENANT
desires to substitute any material business term from SUBLANDLORD's notice which
is more favorable to SUBTENANT, such term shall be incorporated into the
sublease of the subject space. It is understood and agreed that SUBLANDLORD
shall have the right to Sublease to any subsidiary, affiliate, or alliance
company without triggering the foregoing right of first refusal.

        3. TERM. The term of this Sublease shall be for a period of forty three
(43) months commencing on February 15, 1998 ("Commencement Date"), with Basic
Rent due and payable upon the Commencement Date. The Sublease will expire on
September 14, 2001, unless sooner terminated pursuant to any provision hereof,
or by breach of the terms and conditions of this Sublease.

        If for any reason, except as provided for below, SUBLANDLORD has not
delivered possession of the Premises to SUBTENANT by February 15, 1998, in the
condition required hereunder, which shall include completion by SUBLANDLORD, at
its sole cost and expense, of a demising wall separating the existing Premises
and the subleased Premises in a manner reasonably acceptable to SUBTENANT, this
Sublease shall not be void or voidable, nor shall SUBLANDLORD be liable to
SUBTENANT for any loss or damage resulting therefrom: but in such event
SUBTENANT shall not be obligated to pay rent until the date that SUBLANDLORD
delivers possession of the Premises, and the Commencement Date of this Sublease
shall be revised to conform to such date. Notwithstanding the foregoing
sentence, SUBLANDLORD shall not be responsible for any delays whatsoever caused
by or due to the fault of MASTER LANDLORD, or any such delays which may be
caused by, due to, or occur in connection with obtaining MASTER LANDLORD's

the monetary sums due herewith, SUBLANDLORD may (but shall not be required to)
use, apply or retain all or any part of this Security Deposit for the payment of
any other amount which SUBLANDLORD may spend by reason of SUBTENANT's default or
to compensate SUBLANDLORD for any other loss or damage which SUBLANDLORD may
suffer by reason of SUBTENANT's default. If any portion of said Deposit is so
used or applied, SUBTENANT shall, within ten (10) days after written demand
therefor, deposit cash with SUBLANDLORD in that amount sufficient to restore the
Security Deposit to its original amount. SUBTENANT's failure to do so shall be a
material breach of this Sublease. SUBLANDLORD shall not be required to keep this
Security Deposit separate from its general funds, and SUBTENANT shall not be
entitled to interest on such Deposit. So much of the Security Deposit as has not
been properly used, applied, or retained hereunder shall be returned to
SUBTENANT (or at SUBLANDLORD's option, to the last assignee of SUBTENANT's
interest hereunder) at the expiration of the Sublease term and after SUBTENANT
has vacated the Premises. If

SUBTENANT, during the term of the Sublease, successfully completes an Initial
Public Offering (IPO) and can provide proof and evidence thereof, SUBLANDLORD
shall reimburse to SUBTENANT one-half of the security deposit, One Hundred
Eighteen Thousand Four Hundred Eighty Eight and 60/100 ($118,488.60).

        6. USE. SUBTENANT shall use the Premises only for general offices, light
assembly, light manufacturing, storage of electronic components and any other
related legal use in accordance with the Master Lease. SUBTENANT shall not
permit the Premises or any part thereof to be used for any purpose or use in
violation of any law or ordinance, or of the regulation of any governmental
authority, or in any manner that will constitute a nuisance, or in any manner
which would generate or create or emit any toxic waste, hazardous materials, or
environmental damage. SUBTENANT shall not allow any use in violation of any
existing restriction on the Premises. SUBTENANT shall conform its use of the
Premises in every respect to all laws, statutes, ordinances, and regulations now
enforced or hereafter enacted affecting the use of occupancy of the Premises,
provided that SUBTENANT shall not be obligated to correct any condition
pre-dating the Commencement Date for the initial Subleased Premises or the
Expansion Premises, unless the need to comply with such requirement is triggered
by a specific and particular use of the Subleased Premises by SUBTENANT, or by
the construction of alterations by SUBTENANT.

        7. ACCEPTANCE OF PREMISES. SUBTENANT acknowledges that the Premises
contain certain existing tenant improvements with which SUBTENANT is familiar.
SUBTENANT agrees that its act of taking possession of the Premises will
constitute its acknowledgment and acceptance that the Premises are in rentable
and good condition, and that SUBLANDLORD makes no representation or warranty of
any kind whatsoever as to the condition or repair of the Premises. Except as
provided for in Section 7.1 below, SUBTENANT acknowledges and hereby agrees that
SUBTENANT is Subleasing the Subject Premises strictly on an "as is" basis, and
that SUBLANDLORD makes no representation or warranty relating to the suitability
of the Premises for SUBTENANT's intended use, or whether said Premises are in
compliance with all applicable building codes, governmental laws, statutes,
ordinances and regulations (e.g. ADA and Title 24 statutes and laws). Any
additional compliance measures regarding ADA shall be sole responsibility of
SUBTENANT, except as otherwise provided herein.

        7.1 SUBLANDLORD shall deliver the Premises to SUBTENANT, prior to
SUBTENANT's access, with all building utility systems in good working and
operable condition and with the roof in good condition and repair. Any building
system or component that is altered or damaged during SUBTENANT's access to the
Premises for their operation setup, or thereafter during the term of this
Sublease, by SUBTENANT, its agents, employees or contractors, shall be repaired
at SUBTENANT's expense.

        8. INCORPORATION OF MASTER LEASE, ASSUMPTION, TERMINATION OF MASTER
LEASE.

                8.1 This Sublease is expressly subject and subordinate to the
terms and conditions of "The Master Lease" attached hereto as Exhibit A. Subject
and except for



                                      -4-
<PAGE>   5

paragraphs 2, 4, 5, 24, 29C, 37, 38, and 41 of the Master Lease, and all
provisions contained in FIRST AMENDMENT TO LEASE AGREEMENT as they apply to this
Sublease, or as otherwise provided herein, all terms and conditions of the
Master Lease are incorporated herein and are deemed a part of this Sublease.
With respect to the obligation to maintain the Premises, SUBLANDLORD shall
continue to maintain the roof membrane, HVAC and other Building systems,
exterior landscaping and common areas as required under the Master Lease, and
SUBTENANT shall pay to SUBLANDLORD its pro rata share of the reasonable costs so
incurred promptly following receipt of written invoice therefor. The basis for
determining the pro rata share of the reasonable costs shall be; (i) an agreed
percentage of such costs if such costs are incurred in the common (shared) areas
of the Premises, proposed by SUBLANDLORD, on the basis of the relative
difference in the square footage of the Building to be occupied by SUBLANDLORD
and by SUBTENANT, to be 47% allocated to SUBTENANT, and after the Expansion
Premises is occupied by SUBTENANT, to be 65% allocated to SUBTENANT, and (ii)
100% allocated to SUBTENANT if such costs involve services rendered for the
primary benefit of the Premises or the Expansion Premises. Subject to Section 10
herein, references to Landlord and Tenant in the Master Lease shall, for
purposes of this Sublease, be deemed to refer to both MASTER LANDLORD and
SUBLANDLORD, and SUBTENANT, respectively, and reference to the Premises (as
defined in the Master Lease) shall refer to the Premises (as defined herein).

                8.2 Except as otherwise provided herein, SUBTENANT hereby
expressly assumes and agrees to perform and comply with all obligations required
to be kept or performed by SUBLANDLORD pursuant to the provisions of the Master
Lease with respect to the Premises, to the extent incorporated into this
Sublease. SUBTENANT shall not commit or permit to be committed on the Premises
any act or omission which shall violate any term or condition of the Master
Lease. SUBTENANT agrees to indemnify, defend, hold harmless SUBLANDLORD from any
and all claims, damages, costs, and expenses (including reasonable attorney's
fees) with respect to SUBTENANT's non performance or non observance of any such
term and condition.

                8.3 If the Master Lease is terminated, this Sublease shall
terminate simultaneously and the SUBLANDLORD and SUBTENANT shall thereafter be
released from all obligations under this Sublease accruing thereafter (except
that SUBTENANT shall have all of its rights and remedies against SUBLANDLORD if
the Master Lease is terminated as a result of a default by SUBLANDLORD
hereunder, if such default was not the result of a default by SUBTENANT
hereunder, and SUBLANDLORD shall refund to SUBTENANT any unreturned Rent paid in
advance, except as otherwise provided in this Sublease).

        9. UTILITIES/SERVICES. SUBLANDLORD will provide domestic water for
building operation and utility water, natural gas, HVAC, electrical power, and
fire protection systems as necessary for the normal operation of the Subleased
Premises, except for those services described below to be obtained directly by
SUBTENANT. Except as otherwise provided herein, SUBTENANT shall pay as
Additional Rent and in accordance with the Master Lease, its share of all
expenses, based on occupied square footage compared to total square footage of
the Premises,



                                      -5-
<PAGE>   6

for all utilities provided to the Premises. SUBTENANT will reimburse to
SUBLANDLORD the actual cost of electrical power supplied to the Premises. The
parties have assumed that each party will consume electrical power at a similar
rate, and the electrical power costs will, therefore, be allocated initially
according to the percentage shares described in section 8.1. However, if either
party determines that the percentage shares do not accurately reflect the actual
consumption of electrical power by the parties, that party may so inform the
other party in writing. For a period of thirty days following receipt of such
notice, the parties will negotiate in good faith to attempt to allocate more
accurately the costs of electrical power, which may include retaining, at the
joint cost of the parties, an independent, qualified electrical consultant to
investigate actual electrical power usage. Provided, however, SUBTENANT shall
obtain, contract for, and pay 100% of all expenses relating to its personal
electronic communications, data and telephone services, its private security
systems, trash, and recycling services provided to the SUBTENANT's Premises.
SUBTENANT's pro-rata share of the Premises shall be 47% for the initial seven
and one-half (7-1/2) months of occupancy. Beginning October 1, 1998, this share
shall increase to 65% for the remainder of the Sublease term provided that if
SUBTENANT subleases the remainder of the Building, pursuant to paragraph 2
herein, its share shall increase to 100%. It is understood and agreed the cost
to sub-meter the Premises has been deemed prohibitive. Any electrical cost
incremental to SUBLESSOR'S normal operation shall be paid by SUBTENANT according
to the square footage allocation. All service, repairs, and maintenance
responsibilities will be listed on attached Schedule A.

        10. OBLIGATIONS OF SUBLANDLORD. SUBLANDLORD agrees to maintain the
Master Lease during the Term of this Sublease, subject, however, to any
termination of the Master Lease without the fault of SUBLANDLORD. SUBLANDLORD
agrees to comply with or perform all of its obligations under the Master Lease
that SUBTENANT has not assumed under this Sublease. Provided, however,
SUBLANDLORD, does not assume the obligations required to be kept or performed by
the MASTER LANDLORD under the Master Lease. SUBLANDLORD shall upon written
request by SUBTENANT, fully cooperate with SUBTENANT in enforcing the Master
Lease against MASTER LANDLORD, and SUBTENANT shall reimburse SUBLANDLORD for all
of SUBLANDLORD's costs reasonably incurred in connection therewith. SUBLANDLORD
represents and warrants (i) that the document attached as Exhibit A to this
Sublease is a true, correct and complete copy of the Master Lease, that the
Master Lease represents the entire agreement between SUBLANDLORD and MASTER
LANDLORD with respect to the lease of the Premises, (ii) there is no default, or
any condition which with the passage of time or the giving of notice, or both,
would constitute a default, on the part of either party to the Master Lease,
(iii) SUBLANDLORD has not assigned, encumbered or otherwise transferred any
interest of the Tenant under the Master Lease, and (iv) the scheduled Expiration
Date of the Master Lease is September 14, 2001. SUBLANDLORD shall cooperate with
SUBTENANT as reasonably necessary to obtain the consent of MASTER LANDLORD to
any act for which such consent is required.

        11. ALTERATIONS, ADDITIONS, OR IMPROVEMENTS. SUBTENANT shall not make
any alterations, additions or improvements on or to the Premises without first
obtaining the written consent of SUBLANDLORD, which consent will not be
unreasonably withheld or delayed and,



                                      -6-
<PAGE>   7

if required by the Master Lease, the consent of the MASTER LANDLORD. All
permitted alterations, additions and improvements shall be made at the sole
expense of SUBTENANT, and the rights and obligations of the parties regarding
the removal of such alterations, additions and improvements from the Subleased
Premises, and title to the same, shall be governed by Paragraph 10 of the Master
Lease as incorporated herein.

        12. ASSIGNMENT OR SUBLEASE. SUBTENANT shall have the Sublease rights of
SUBLANDLORD set forth in Paragraph 29 of the Master Lease, subject to
SUBLANDLORD and MASTER LANDLORD's approval to the extent required hereunder. All
Sublease profits (100%) shall be paid to SUBLANDLORD.

        13. HAZARDOUS MATERIALS. Notwithstanding anything contained in Paragraph
18 of the Master Lease, SUBTENANT shall not be entitled to use or store any
Hazardous Materials or Substances on or about the Premises without first
obtaining the express written consent of SUBLANDLORD, which may be given or
withheld in SUBLANDLORD's absolute and sole discretion. Except as otherwise
provided in this Section 13, the provisions of Paragraph 18 of the Master Lease
apply to this Sublease. Provided however, that SUBLANDLORD's consent shall not
be required for normal use, in compliance with applicable Environmental Laws of
customary household and office supplies (SUBTENANT shall first provide
SUBLANDLORD with a list of said materials use), such as mild cleaners,
lubricants and copier toner.

        14. BROKERS. SUBLANDLORD and SUBTENANT hereby agree, consent to and
acknowledge that Cooper/Brady Corporate Real Estate Services has represented the
SUBLANDLORD and Colliers Parrish International, Inc. has represented the
SUBTENANT ("Brokers") in connection with this Sublease. SUBLANDLORD and
SUBTENANT represent that no other brokers have been retained in connection with
this Sublease and agree to indemnify, defend and hold harmless the other in
connection with any commission claims brought in connection with their
respective activities on this Sublease. SUBLANDLORD shall pay all commissions
payable to Brokers in connection with this Sublease in accordance with a
separate agreement between SUBLANDLORD and Cooper/Brady Corporate Real Estate
Services.

        15. CONSENT OF MASTER LANDLORD. This Sublease requires the consent and
agreement of MASTER LANDLORD and the effectiveness of this Sublease is hereby
expressly conditioned upon receiving such consent. SUBLANDLORD and SUBTENANT
agree to timely execute MASTER LANDLORD's standard Consent to Sublease Agreement
form (a sample copy is provided herein as Exhibit C), which shall be prepared by
MASTER LANDLORD, and shall set forth MASTER LANDLORD's acknowledgment of this
Sublease, and which shall be subject to review and reasonable approval of the
parties. Said Consent shall apply to this Sublease only, and shall not be deemed
as MASTER LANDLORD's consent to any other sublease.

        16. MISCELLANEOUS PROVISIONS.

                A. SIGNAGE. Notwithstanding anything contained in the Master
Lease, SUBTENANT shall have building signage rights at the front entrance on
North First Street and the subject Premises as reasonably allowed by
SUBLANDLORD, MASTER LANDLORD,



                                      -7-
<PAGE>   8

CITY OF SAN JOSE, and any of the covenant, codes, and restrictions per Master
Lease. All costs of related signage shall be paid by SUBTENANT.

                B. SUBTENANT EQUIPMENT. SUBTENANT will require roof access, in
an ongoing process, to inspect and demonstrate equipment related to their
business. Any roof penetrations will be done in accordance with the Master
Lease. Notwithstanding anything contained in the Master Lease, any damage to the
roof through SUBTENANTS actions shall be fully repaired at SUBTENANTS cost.
Subject to the approval of the MASTER LANDLORD, if required by the Master Lease,
SUBTENANT shall have the right to install an LN2 plumbing system, at its sole
cost, in accordance with the Master Lease and this Section 16 of the Sublease,
and conforming to all codes, covenants, and restrictions with the City of San
Jose. SUBTENANT shall conform with all covenants codes and restrictions of the
Master Lease and the City of San Jose.

                C. USE OF SUBLANDLORD EMPLOYEES BY SUBTENANT. In the event
SUBTENANT uses any employees of SUBLANDLORD for any of it's purposes for
outfitting or work arrangements, SUBTENANT agrees that it will pay any charge
therefore imposed by SUBLANDLORD and assume the sole liability and
responsibility with respect to any personal injury, including death, or property
damage to or in connection with such use.

                D. HOLDING OVER. If SUBTENANT holds over after the expiration of
the Master Lease and SUBLANDLORD pays holdover rent on the entire Premises due
to SUBTENANT's holdover, SUBTENANT shall assume the entire holdover obligation
due under Master Lease.

        17. NOTICES. All notices to be given to SUBTENANT may be given in
writing, personally, or by depositing the same in the United States mail,

                         LANDLORD'S CONSENT TO SUBLEASE

        North San Jose Interests, a California limited partnership, as successor
in interest to John A. Sobrato, Trustee under trust agreement dated August 29,
1979, as Amended, Sobrato Interest II, a California general partnership, and
John Michael Sobrato or his successor, Trustee Under Revocable Trust Agreement
dated April 28, 1989, as amended, FBO Ann Sobrato ("Landlord"), as Landlord
under that certain Lease (the "Lease") dated May 30, 1990 and a First Amendment
to Lease dated March 12, 1991, by and between Landlord and Siemens Pyramid
Information Systems, Inc., a Delaware corporation ("Tenant"), as Tenant, subject
to and specifically conditioned upon the following terms and conditions hereby
grants its consent to the Sublease dated December 15, 1997 made by and between
the Tenant, as sublandlord, and Netro Corporation, a California corporation
("Subtenant"), as subtenant, a copy of which is attached as Exhibit A ("the
Sublease"), covering that certain premises (the "Premises") commonly known as
3860 North First Street, San Jose, California.

        As conditions to the consent of Landlord to the Sublease, it is
understood and agreed as follows:

        1.      NO RELEASE. This Consent to Sublease shall in no way release the
Tenant or any person or entity claiming by, through or under Tenant, including
Subtenant, from any of its covenants, agreements, liabilities and duties under
the Lease, as the same may be amended from time to time, without respect to any
provision to the contrary in the Sublease.

        2.      SPECIFIC PROVISIONS OF LEASE AND SUBLEASE. This Consent to
Sublease consenting to a sublease to Subtenant does not constitute approval by
Landlord of any of the provisions of the Sublease document or agreement thereto
or therewith; nor shall the same be construed to amend the Lease in any respect,
any purported modifications being solely for the purpose of setting forth the
rights and obligations as between Tenant and Subtenant, but not binding
Landlord. The Sublease is, in all respects, subject and subordinate to the
Lease, as the same may be amended. Furthermore, in the case of any conflict
between the provisions of this Consent to Sublease or the Lease and the
provisions of the Sublease, the provisions of this Consent to Sublease or the
Lease, as the case may be, shall prevail unaffected by the Sublease.

        3.      LIMITED CONSENT. This Consent to Sublease does not and shall not
be construed or implied to be a consent to any other matter for which Landlord's
consent is required under the Lease, including, without limitation, any
Alterations under the Lease.

        4.      TENANT'S CONTINUING LIABILITY. Tenant shall be liable to
Landlord for any default under the Lease, whether such default is caused by
Tenant or Subtenant or anyone claiming by or through either Tenant or Subtenant,
but the foregoing shall not be deemed to restrict or diminish any right which
Landlord may have against Subtenant pursuant to the Lease, in law or in equity
for violation of the Lease or otherwise, including, without limitation, the
right to enjoin or otherwise restrain any violation of the Lease by Subtenant.

        5.      DEFAULT BY TENANT UNDER THE LEASE. If Tenant defaults under the
Lease, Landlord may elect to receive directly from Subtenant all sums due or
payable to Tenant by


<PAGE>   2
Subtenant pursuant to the Sublease. Upon written notice from Landlord, Subtenant
shall thereafter pay to Landlord any and all sums due or payable under the
Sublease. In such event, Tenant shall receive from Landlord a corresponding
credit for such sums against any payments then due or thereafter becoming due
from Tenant.

        6.      TERMINATION OF LEASE. If at any time prior to the expiration of
the term of the Sublease the Lease shall terminate or be terminated for any
reason, the Sublease shall simultaneously terminate. However, Subtenant agrees,
at the election and upon written demand of Landlord, and not otherwise, to
attorn to Landlord for the remainder of the term of the Sublease, such
attornment to be upon all of the terms and conditions of the Lease, except that
the Base Rent set forth in the Sublease shall be substituted for the Base Rent
set forth in the Lease and the computation of Additional Rent as provided in the
Lease shall be modified as set forth in the Sublease. The foregoing provisions
of this paragraph shall apply notwithstanding that, as a matter of law, the
Sublease may otherwise terminate upon the termination of the Lease and shall be
self-operative upon such written demand of the Landlord, and no further
instrument shall be required to give effect to said provisions. Upon the demand
of Landlord, however, Subtenant agrees to execute, from time to time, documents
in confirmation of the foregoing provisions of this paragraph satisfactory to
Landlord in which Subtenant shall acknowledge such attornment and shall set
forth the terms and conditions of its tenancy.

        7.      SUBLEASE PROFITS. Pursuant to Section 29 of the Lease, provided
the Sublease remains in full force and effect, Tenant agrees to pay to Landlord
each month along with the base monthly rent due under the Lease, the sum
outlined on the attached spreadsheet representing Landlord's fifty percent (50%)
share of the amount by which the consideration received pursuant to the Sublease
exceeds the amount due to Landlord under the Lease less the reasonable
subletting costs.

        8.      NO WAIVER; NO PRIVITY. Nothing herein contained shall be deemed
a waiver of any of the Landlord's rights under the Lease. In no event, however,
shall Landlord be deemed to be in privity of contract with Subtenant or owe any
obligation or duty to Subtenant under the Lease or otherwise, any duties of
Landlord under the Lease being in favor of, for the benefit of and enforceable
solely by Tenant.

        9.      NOTICES. Subtenant agrees to promptly deliver a copy to Landlord
of all notices of default and all other notices sent to Tenant under the
Sublease, and Tenant agrees to promptly deliver a copy to Landlord of all such
notices sent to Subtenant under the Sublease. All copies of any such notices
shall be delivered personally or sent by United States registered or certified
mail, postage prepaid, return receipt requested, to Landlord.

         accredited Registrar have an equal registration (in case of overseas
         supplier).

(b)      Supplier commits to having a continuous improvement program in place
         which will allow it to attain and maintain "acceptable" ratings (or
         equivalent) on all quality system elements per Supplier Capability
         Assessment (SCA), or other type of Company assessment, as periodically
         performed by Company. An "acceptable" element is defined as one where
         the quality system meets the "general intent" of the quality system
         element and is fully implemented to maintain the quality system and
         product quality. No significant deficiencies encountered that would
         jeopardize the quality system, and product quality and/or reliability.

(c)      Supplier commits to establish quality control (QC) verification points
         throughout the manufacturing process. These verification points should

                                      -5-
<PAGE>   9

         and with the use of statistically valid sampling plans, that MATERIAL
         conforms to Supplier's manufacturing, product and process
         specifications, standards of acceptable workmanship, as well as other
         specification's which may be provided by Company. Company reserves the
         right to review these QC points and make suggestions for improvement.
         Supplier commits to address these suggestions through the
         implementation of appropriate corrective actions.

(d)      Supplier commits to establish an end of the line Quality Assurance
         product audit on material by 12/1/98. The focus of this audit shall be
         to replicate user application of MATERIAL as specified by Company's
         customer. Test and examination of MATERIAL under the quality audit
         shall be at a system level, and shall include but is not limited to:

         a)       Exercising said MATERIAL over the full spectrum of temperature
                  ranges over which MATERIAL is designed to operate.

         b)       Full operation of MATERIAL over a period of time not less than
                  to ensure best practice and quality.

         c)       A system for continuous monitoring of all primary and
                  ancillary product functions and fault detection of the
                  MATERIAL while under this test.

         Supplier shall continuously review customer return data to ensure that
         the scope of the product quality assurance audit function includes the
         requirement(s)/condition(s) under which the return failed.

         Supplier shall perform a detailed failure mode analysis of all MATERIAL
         found defective through the quality assurance audit in line with the
         requirements and process outlined in paragraph F.

         Supplier agrees to provide to Company on a monthly basis, results of
         the quality assurance product audit in a format specified by Company.

(e)      Supplier commits to establishing a program of tracking return rates.
         The following is the suggested method for tracking, calculating, and
         tracking customer returns. Company and supplier may mutually agree to
         modify this method as appropriate. MATERIAL which has been in operation
         for any period of time up to, and including one full year shall be
         considered part of this tracking program. For the purpose of this
         article, the term "product" shall be used to define the lowest
         replaceable unit (lru) of MATERIAL supplied to Company.

         For the purpose of calculating the return rate, the following
         definitions apply:

         RTM(x) = The quantity of lru's which were manufactured in the Target
         Month;(x) that have been returned during the period beginning the 4th
         month after the Target Month and ending the 15th month from the Target
         Month.



                                      -6-
<PAGE>   10

         PTM(x) = The total number of lru's in the Target Month;(x).

         All returns will be included in the calculation of the return rate
         including, but not limited to, failures, no trouble founds, and
         recalls.

         A Target Quarter Return Rate (TQRR) is to be calculated using the
         following equation:

         TQRR = 10,000 x [[RTM(l)+RTM(2)+RTM(3)]/[PTM(l)+PTM(2)+PTM(3)]]

         Where:

         "(1)" refers to the first month of the Target Quarter "(2)" refers to
         the second month of the Target Quarter "(3)" refers to the third month
         of the Target Quarter

         This calculation shall be made on a quarterly basis for the product
         manufactured under this contract.

         The Supplier agrees to update and report TQRR's on a quarterly basis to
         Company, and to comply with the Annual Return Rate (ARR) requirement in
         accordance with the following schedule:

<TABLE>

</TABLE>

         The ARR is 10,000 times the summation of the number of returns received
         for the Target Months of the Manufacture Year divided by the summation
         of the manufacturing populations for the Target Months of the
         Manufacture Year. Supplier commits to provide to company on a monthly
         basis, the cumulative year to date results of the ARR until the annual
         measurement requirement is due.

(f)      Supplier commits to establishing a system for tracking and analysis all
         MATERIAL returned by Company to it, as well as any MATERIAL failures
         which occur through the company's end of the line quality assurance
         audit. For all MATERIAL in the above two categories, supplier shall
         perform a failure mode analysis, which at a minimum will be down to the
         component level. Component level failure modes will be recorded, and
         failed components found defective will be accumulated for the purpose
         of determining repetitive occurrences.

<PAGE>   11

         Material shall be considered defective if it fails to meet the warranty
         specifications under this Agreement (including performance and
         appearance Specifications) or if during customer testing, installation,
         or use, the MATERIAL fails to operate as expected or specified.

         If the analysis of a Company return is found to be within the
         specifications of this agreement (i.e., a no trouble found condition),
         then Supplier shall track these no trouble found conditions and notify
         Company of said findings at a minimum of a monthly interval, so that
         appropriate investigative measures may be taken to determine the root
         cause.

(G)      If a Target Quarter Return Rate (TQRR) is found to exceed the
         applicable ARR requirements specified in paragraph E, or repetitive

         c)       Repair and/or replace previously shipped MATERIAL that may
                  contain the same problem trend. In the event that Company
                  incurs costs due to such repair and/or replacement, including
                  but not limited to labor and shipping costs, Supplier shall
                  reimburse Company for such costs. Supplier shall bear risk of

                  MATERIAL.

         Supplier and Company shall mutually agree in writing as to the
         implementation schedule of the corrective action plan. Supplier agrees
         to use its best efforts to implement the plan in accordance with the
         agreed upon schedule. It is also agreed that the Company shall be
         entitled to postpone at no charge to Company, further deliveries of
         orders until such time as the remedy is implemented consistent with
         this Article.

(H)      As part of a program of continuous improvement, Supplier agrees to
         establish annually, improvement goals for a series of key quality

In the event that Supplier exceeds the above maximum interval, then in addition
to all other rights and remedies at law or equity or otherwise, and without any
liability or obligation of Company, Company shall have the right to: (a) cancel
such purchase order, or (b) extend such delivery date to a later date, subject,
however, to the right to cancel as in (a) preceding if delivery is not made or

Supplier acknowledges that a pattern of failure to deliver fully conforming
MATERIAL within the time specified in this Agreement or in an order placed
pursuant to this Agreement will cause serious damage to Company. If a pattern of
late or non-conforming delivery emerges, Supplier agrees to pay to Company, as
liquidated damages sustained by Company resulting from such delays, and not as a

Supplier's failure to deliver conforming MATERIAL within the time specified in
this Agreement or such order, shall give Company the right at any time to cancel
this Agreement or any orders, placed pursuant to this Agreement, in whole or in
part, and to place no future orders under this Agreement. If Company elects to
cancel an order on which liquidated damages for late delivery are still
accruing, such accrual shall cease on the effective date of the cancellation.

These provisions concerning late delivery of conforming material are intended to
be and shall be cumulative and in addition to every other remedy now or
hereafter possessed by Company for other than late delivery, including but not
limited to its rights to recover damages under the WARRANTY clause in this
Agreement.

Company shall be allowed to cancel purchase orders or items within purchase
orders subject to the following fee schedule:

supplier has issued an end of life notice to the Company, the term of the
availability of maintenance, replacement and repair parts shall be limited by
the end of life terms. The price for the MATERIAL and Parts shall be the price
set forth in Supplier's then current agreement with Company for said MATERIAL or
Parts or, if no such agreement exists, at a price agreed upon by Company and
Supplier. If the parties fail to agree on a price, the price shall be a
reasonably competitive price for said MATERIAL or Parts at the time for
delivery. The MATERIAL and parts shall be warranted as set forth in the WARRANTY
clause of this Agreement.

In the event Supplier fails to supply such MATERIAL or parts and Supplier is
unable to obtain another source of supply for Company, then such failure or
inability shall be considered noncompliance with this clause and Supplier shall,
license to Company, or another manufacturer under contract with Company, the
technical information or other rights so that Company can manufacture, have
manufactured or obtain such extended or enhanced products, solely for the
purposes contemplated by this Agreement, subject to the negotiation of
reasonable terms and conditions compensating Supplier for such information,
which Supplier and Company agree to negotiate in good faith.

The technical information includes, by example, and not by way of limitation:
(a) manufacturing drawings and specifications of raw materials and components
comprising such MATERIAL or Parts, (b) manufacturing drawings and specifications
covering special tooling and the operation thereof, (c) a detailed list of all
commercially available MATERIAL or Parts and components purchased by Supplier on
the open market disclosing the MATERIAL or part number, name and location of the
Supplier and price lists for the purchase thereof, and (d) one complete copy of
the source code used in the preparation of any software licensed or otherwise
acquired by Company from Supplier under this Agreement.

When the supplier initiates an End of Life (EOL) on a product, it will do so
under the following terms:


<TABLE>
<S>                                   <C>
Supplier Issues EOL Notice:            EOL Notice Date
Last Order Opportunity                 Minimum [***] from EOL Notice Date
RMA Support                            [***] years from EOL Notice Date
Software Release Support:              Earlier of [***] Releases of two years from EOL Notice Date
</TABLE>

In the absence of FORCE MAJEURE conditions of Article 38, Supplier shall accept
orders for any quantity of EOL MATERIAL from the Company in the period from the
EOL notice date to the Last Order Opportunity. Supplier will use best efforts to
maintain its standard delivery schedules on these orders.

If Supplier replaces EOL MATERIAL with a new generation of product which is
functionally equivalent, the software interface to the new generation unit must
be backward compatible to the EOL MATERIAL.

         a)       The receiving party shall use Information only for the
                  Purpose, shall hold Information in confidence using the same
                  degree of care as it normally exercises to protect its own
                  proprietary information, but not less than reasonable care,
                  taking into account the nature of the Information, and shall
                  grant access to Information only to its employees who have a
                  need to know, shall cause its employees to comply with the
                  provisions of this Agreement applicable to the receiving
                  party, shall reproduce Information only to the extent
                  essential to fulfilling the Purpose, and shall prevent
                  disclosure of Information to third parties. The receiving
                  party may, however, disclose the Information to its
                  consultants and contractors with a need to know; provided that
                  by doing so, the receiving party agrees to bind those
                  consultants and contractors to terms at least as restrictive
                  as those stated herein, advise them of their obligations, and
                  indemnify the disclosing party for any breach of those
                  obligations.

         b)       Upon the disclosing party's request, the receiving party shall
                  either return to the disclosing party all Information or shall
                  certify to the disclosing party that all media containing
                  Information have been destroyed. Provided, however, that an
                  archival copy of the Information may be retained in the files
                  of the receiving party's counsel, solely for the purpose of
                  proving the contents of the Information.

7.       The foregoing restrictions on each party's use or disclosure of
         Information shall not apply to Information that the receiving party can
         demonstrate:

         a)       was independently developed by or for the receiving party
                  without reference to the Information, or was received without
                  restrictions; or

         b)       has become generally available to the public without breach of
                  confidentiality obligations of the receiving party; or

         c)       was in the receiving party's possession without restriction or
                  was known by the receiving party without restriction at the
                  time of disclosure; or

         d)       is the subject of a subpoena or other legal or administrative
                  demand for disclosure; provided, however, that the receiving
                  party has given the disclosing party prompt notice of such
                  demand for disclosure and the receiving party reasonably
                  cooperates with the disclosing party's efforts to secure an
                  appropriate protective order.

8.       Access to Information hereunder shall not preclude an individual who
         has seen such Information for the purposes of this Agreement from
         working on future projects for the receiving party which relate to
         similar subject matters, provided that such individual does not make
         reference to the Information and does not copy the substance of the
         Information during the Confidentiality Period. Furthermore, nothing
         contained herein shall be construed as imposing any restriction on the
         receiving party's disclosure or use of any general learning, skills or
         know-how developed by the receiving party's personnel under



                                      -22-

         this Agreement, if such disclosure and use would be regarded by a
         person of ordinary skill in the relevant area as not constituting a
         disclosure or use of the Information.

9.       As between the parties, all Information shall remain the property of
         the disclosing party. By disclosing Information or executing this
         Agreement, the disclosing party does not grant any license, explicitly
         or implicitly, under any trademark, patent, copyright, mask work
         protection right, trade secret or any other intellectual property
         right. THE DISCLOSING PARTY DISCLAIMS ALL WARRANTIES REGARDING THE
         INFORMATION, INCLUDING ALL WARRANTIES WITH RESPECT TO INFRINGEMENT OF
         INTELLECTUAL PROPERTY RIGHTS AND ALL WARRANTIES AS TO THE ACCURACY OR
         UTILITY OF SUCH INFORMATION.

information provided pursuant to this Agreement may be subject to United States
export laws and regulations and agree that any use or transfer of such items

any other designation or drawing of Lucent Technologies, Supplier, or their
affiliates. Supplier shall remove or obliterate any such Identification prior to
any use or disposition of any material rejected or not purchased by Company.

names, insignia, symbols, decorative designs, or packaging designs of Company,

manner in which such Insignia will be affixed must be approved in writing by
Company in accordance with standards established by Lucent Technologies as
applicable. Lucent Technologies Inc., (Company) shall retain all right, title
and interest in any and all packaging designs, finished artwork, and separations

                        situation that causes critical impact to the Customer's
                        business operation. The Customer, the

                        Reseller and/or System Integrator, and Netro will commit
                        all resources necessary to resolve the situation.

                        Priority 1 problems are given the highest level of
                        attention and are immediately addressed by the Netro
                        Technical Assistance Center. Netro Engineering will
                        become engaged as necessary at the request of Netro

        Priority 2:     The operation of an existing network or link or a test
                        network imminently due to go live is severely degraded,
                        or significant aspects of the Customer's business
                        operation are being negatively impacted by unacceptable
                        hardware or software performance. The Customer, the
                        Reseller and/or System Integrator and Netro will make
                        every reasonable effort to resolve the situation in a
                        timely manner.

        Priority 3:     Operational performance of the network is impaired while
                        most business operations remain functional. The
                        Customer, the Reseller and/or System Integrator and
                        Netro will commit resources during Standard Business
                        Hours to restore service to satisfactory levels.

        Priority 4:     Information or assistance is required on Netro product
                        capabilities, installation, enhancement requests or
                        configuration. There is clearly little or no impact to
                        the Customer's business operation. Netro is willing to
                        provide resources during Standard Business Hours to
                        provide information or assistance as requested. Netro

                        developments to resolve requests for improvement by the

                        around, a resolution through a new feature included in a
                        future release, revised documentation or a statement
                        that Netro will not be modifying the product as
                        suggested.

IX.     REPAIR ACTIVITIES:

        1.      HARDWARE UPGRADES: At customer's request, units received by
                Netro for repair will also be upgraded to the latest engineering
                revision level whenever practical.

        2.      TURNAROUND: REPAIR AND RETURN.

                Netro will make all reasonable efforts to repair and ship the
                Customer's unit within 20 business days of receipt of the unit
                at Netro. (This applies to units repaired under Warranty or
                under the Netro Reseller Support Contract (if covered) outside
                of the Warranty period)

                It is important that the Reseller and the Customer follow
                Netro's RMA (Return Material Authorization) process. The
                Reseller is urged to document each service request made by the
                Customer and retain a full log, with a resolution of each case.
                Cases referred to Netro will all be documented by Netro against
                an RMA number, and will be cleared by a resolution and
                description of the cause, which will also be documented by
                Netro. Netro's RMA process is initiated by contacting the Netro
                Technical Assistance Center. The Reseller and the Customer are
                responsible for the proper packaging and the payment of shipping
                related fees for shipment of the product of Netro. Netro is
                responsible for the proper packaging and payment of shipping
                related fees for shipment of payment of shipping related fees
                upon return of the product to the Reseller (or Customer as
                required by the Reseller).

        3.      TURNAROUND: ADVANCE REPLACEMENT.

                Netro will make all reasonable efforts to ship a replacement
                unit to the customer within 5 business days of notification that
                the Customer requests an "Advance Replacement."

                Customer must return the defective unit to Netro within 15
                business days. Netro retains the right to invoice units not
                received within 15 business days at the then current list price.
                Customer or Reseller will assume ownership of the replaced unit
                and Netro will assume ownership of the repaired unit.

                Shipping and packaging terms and responsibilities and costs are
                as for normal `Turnaround: Repair and Return' as defined above.

                                   TRANSACTION

The Warranty Eligibility System (WES) tracks a serialized product from
manufacturing to the customer and provides up-to-date information about the
product's warranty status. In order to accomplish this, WES receives data from
entities whose functions affect an item's warrantability.

At the end of the manufacturing, shipping, or repair processes, information
about an item will be sent to WES for inclusion on the Warranty Database. This
file can be sent to WES using

1)      UNIX file transfer at,

        [***] where origsystem is the UNIX machine originating the file XX is a
        location code entry in location table and NNNN is the sequence number on
        the header record.

2)      or electronically sent to,

        [***]

3)      or via internet,

        [***]

4)      or by placing the file on a floppy disk and mailing the disk directly to
        the WES group at:

        Lucent Technologies, Inc.
        Westwood of Lisle
        Attn:  [***]
        2443 Warrenville Road
        Lisle, IL  60532

Batch files received for processing by WES must be processed by a Header Record
as attached. Following the Data Records must be a Trailer Record also attached.
The Header and Trailer Records are interrogated by WES and messages are returned
to the sending location indicating the status of each file transmitted to WES.

services and material, if any, provided by Supplier to Company under this
agreement up to and including the effective date of termination. Such payment
will constitute a full and complete discharge of Company's obligations under
this Agreement.

In the event that Lucent terminates the Agreement prior to shipment of the
[***] GHz product to Lucent's customers, Netro agrees to pay a rebate to Lucent
from its sales of the [***] GHz radios. The rebate will be paid at the rate of
[***]% of the net sales of the [***] GHz radios up to a maximum rebate of
Lucent's funding prior to termination. The rebate of funding shall survive the
original OEM agreement in time if Lucent's funding has not been fully rebated.
If Company terminates the accelerated development of [***] GHz product, Company
will not recognize any preferred pricing as described in Article 3 of the OEM
agreement for [***] GHz product.

Lucent agrees that it will provide a $[***] minimum order to Netro for [***] GHz
products as soon as it is able to do so but no later than December 31, 1998.
Lucent realizes that unless a firm order of at least [***] dollars is placed for
[***] GHz equipment, there is no economic justification to continue the
development effort beyond the prototype stage. Hence in the absence of a firm
order of at least [***], it is the intention of both Lucent and Netro to halt
the [***] GHz development effort after the completion of the prototype

                        TO SUPPLEMENTAL AGREEMENT NR. 01



                QUALITY ASSURANCE CHARACTERISTICS AND CONDITIONS



Netro's quality program is an integral part of Netro's business process and is
involved in all aspects of the activities that occur within Netro on a daily
basis. In the area of Netro products, the quality program starts at the earliest
phase in the new product design and progresses throughout the life cycle of the
product. It includes design control's and evaluations, manufacturing readiness
evaluations prior to release for manufacture, full documentation of all parts,
materials and processes, material and vendor testing and controls, full product
evaluation and testing prior to shipment to the end users, and a complete
customer service activity to resolve any issues that may occur after shipment.

Netro's quality program is based on ISO-9001 Quality System Requirements and
Netro has been registered by the British Standards Institute (BSI) after having
been evaluated through an exhaustive set of audits to those requirements.
Netro's registration number is #xxxxxx, and this initial registration was
received in March of 1997. Since that time, Netro has had a follow-up six month
audit by BSI and successfully passed this additional evaluation. Continuing
audits of the Netro system can be expected to be completed on a six month basis.

In addition to the BSI registration, Netro has been evaluated and audited by the
British Approvals Board for Telecommunications (BABT) and has received their
Full Quality Assurance Approval (FQAA) so that Netro quality system and testing
procedures have been approved for testing of the Digital products produced by
Netro. FQAA approval was received after a comprehensive audit of Netro's quality
system that was similar in content and thoroughness to the ISO registration
audit. This approval was also received in March of 1997 and since that time,
Netro has had a successful follow-up audit which allows for continuation of
Netro's FQAA approval.

To assure that all products produced by Netro meet the requirements specified by
Netro's product specifications or the special requirements imposed by Netro
customers, Netro has implemented a comprehensive system of quality assurance
analysis and test that starts at the earliest part of the production process:

- -    Components are carefully selected to assure that their performance had been
     proven in the environments that Netro's products will see in use. Custom
     parts and Materials are specially tested and evaluated by Netro to assure
     reliable performance. To the extent possible, Supplier Quality Systems must
     meet the requirements of ISO-9000. When this is not possible, Netro
     evaluates the Supplier systems to assure that their approach to quality
     assurance provides products that meet all applicable requirements.



                                      -16-
<PAGE>   17

- -    Material received by Netro, is evaluated upon receipt to see that it meets
     specified requirements. Material that is found to be discrepant is
     evaluated to identify the specific problem found and the supplier contacted
     to determine the corrective and preventive action that must be taken so
     that defective material is not received in the future.

- -    As product moves through the production line, it is evaluated by trained
     production operators to assure that it meets all of the quality
     requirements necessary for acceptable product performance. An on line
     quality information system (Quality Feedback System) is utilized to
     maintain the data associated with evaluations and test. Each step in the
     production process is entered into QFS by the use of bar codes, and if any
     step should be missed, or has defects associated with it, the system will
     prevent the product from moving on in the production flow. Data from this
     system is utilized to analyze failure modes and to establish the corrective
     and preventive actions necessary to eliminate the problem.

- -    At the system level, products are subjected to a wide range of tests and
     evaluations to assure that they will work in the customers applications.
     These tests include Environmental Stress Screening (ESS), electrical
     performance tests, calibration tests, and any other tests and evaluations
     deemed necessary to assure superior performance. Burn-in tests and other
     tests necessary to weed out early failures are conducted at various levels
     of the production cycle.

- -    All products are packaged in specially designed materials and containers
     that have been tested to assure that they will survive the rigorous and
     difficult environments that are seen in transporting and handling Digital
     Radio products.

Continuous improvement and total customer satisfaction are the cornerstones of
Netro's quality system and reflect the major content of Netro's quality policy.
Continuous improvement is a way of life at Netro. Not only improvement in the
quality of the products Netro produces, but improvement in product performance,
in Netro's business systems, and overall service to the customers. In its drive
to achieve total customer satisfaction Netro has fully staffed a Customer
Services Organization that responds to customer requirements and issues as they
occur. This organization stands ready to respond to Customers requests as they
arise and is continuously seeking ways of improving overall service.

Netro's Quality Assurance Manual has been written to reflect the actual
operating methods employed by Netro during all phases of its business and
product life. This manual describes all parts of the Netro quality Assurance
System and is available for review by customers. If forms the basis for a
comprehensive system of documents that describe the actual procedures that are
used by Netro personnel in the performance of their duties. Employee's are
thoroughly trained in all aspects of the Quality Manual and the Company
Operating Procedures and part of each employee responsibility is to understand
and use Netro's quality policy and overall quality system. This well trained and
competent work force assures Netro customers of superior radio products.

Netro will also deliver a copy of its quality manual to Italtel promptly when it
is available.

                     Customer will commit resources as deemed necessary to
                     resolve the situation. The situation may be resolved by a
                     fix, a workaround, an upgrade to the software, or an
                     operational change that allows the customer to gain
                     operational stability.

Priority 3:          Operational performance of the network is impaired while
                     most business operations remain functional. Italtel, Netro
                     and the Customer are willing to commit resources during
                     Standard Business Hours to restore service to satisfactory
                     levels. The situation may be resolved by a fix, a
                     workaround, an upgrade to the software, or an operational
                     change that allows the customer to gain operational
                     stability.

Priority 4:          Information or assistance is required on Netro product
                     capabilities, installation, or configuration. There is
                     clearly little or no impact to the Customer's business
                     operation. Netro and Customer are willing to provide
                     resources during Standard Business Hours to provide
                     information or assistance as requested. If a fix or
                     workaround is deemed necessary, it may be provided in a
                     later release of the software or the Customer may be
                     requested to upgrade to a higher level of software to
                     resolve the issue.

Feeder Product for the Feeder Market, the characteristics and specifications of
which are described in Annex 1 hereto.

        1.02. Since the Feeder Product shall be developed by adapting and using
as a basis the Netro PMP Product (AIRSTAR), in the event that third party's
software is used in the Netro PMP Product, Netro warrants to Italtel that such
third party's software is available on commercially reasonable terms and will
not prejudice in any way Italtel rights under this Supplemental Agreement.

        Netro will provide access to the third party's software at the same
price and conditions obtained by Netro.

        Netro further warrants that it owns or has rights to all intellectual
property necessary for the development and manufacture of AirStar and the Feeder
Product, free and clear of any adverse claims of any third party.

3.      SYSTEM SPECIFICATIONS

3.1     TRAFFIC TRANSPORT DEFINITION

Each [***] may require n = [***] to [***] kbit/s (DS0) channels. In a [***]
application, each channel consists of [***] x [***] kbit/s sub-channels, one of
which may be a "[***]" channel. The Feeder transports the nxDS0 channels
transparently, regardless of signaling content. Base Stations i and j may have
ni and nj channels, respectively, and in general, ni needs not be equal to nj.

The [***] channels are provided at the [***] as [***]. Only n out of the full
line capacity is forwarded to the [***]. The air interface will transmit only
the n provisioned channels but these provisioned channels are always
transmitted, whether active or not. The [***] need not be contiguous. The [***]
are full duplex. These channels are delivered as [***] interfaces at the [***]
interface, such that each [***] line is an aggregate of multiple base stations
traffic. The mapping of [***] channels is such that all channels from one [***]
terminate in the same [***].

The bandwidth provisioning is semi permanent. A change requires human
intervention via NMS and is considered to be an non-frequent event. A change in
capacity will interrupt the service for that particular mobile base station.

These specifications are summarized below.

The TS is an outdoor unit including the radio section and [***] interface. It is
equivalent to a single box containing the AirStar SRU and SAS, however only one
[***] is required as an interface. The [***] is lightning protected.

The TS includes the functions of the SAS digital card (Subscriber Interface
Card), excluding unneeded stuff options, but the card is modified to the outdoor
temperature range. It is TBD whether the SIC card will be used as-is or it will
be redesigned for a new form-factor.

The TS includes also the SAS modem card, which is de-stuffed for unneeded
functions, such as the coax multiplexer and telemetry (radio control) modem.

The rest of the TS is the SRU function, which includes most of the AirStar
modules unchanged. Two modules that can be slightly depopulated are the Radio
Unit Controller (RUC) and If module.

The TS will have an integral [***] antenna compliant with [***] for the [***]
band, and an optional [***] mm parabolic-reflector antenna, that may use a
different TS enclosure than the lens-horn. For [***] GHz bands an
[***]-compliant flat antenna will be used.

The polarization can be either [***] or [***]. A field setting of
polarization is desired, but a factory setting is acceptable. The current
elongated shape of the SRU is desired to be maintained with the TS, although it
may be enlarged to accommodate the extra hardware.

No local craft interface is required, however the design will allow optional
[***] port. This port will be used for trouble shooting purpose, not for
configuration and not on a permanent basis.

The TS will have optional [***] protection switching option including switching
of the [***] port.

A backup control unit will be developed to provide both battery backup and E1/T1
switching for the mobile base station.

3.5     CENTRAL STATION

The Central Station is located normally next to a mobile BSC. It provides access
at increments of [***][***]. The main building blocks are;

Central Station Shelf (CSS) consisting of a card cage [***], and including AC or
DC redundant power supplies and fan-cooling shelves. This card cage can host the
CSC (identical to AirStar BSC) card.

The first generation CSC card has two channels, each supporting [***][***]
payload. The CSC uses one channel for communication with a modem unit (CMU) that
is attached to a CRU (identical to a BRU). The other channel in the CSC is
connected to a second port in the CMU. This port is converted to four local
El/T1 interfaces by a card identical to an existing SIC Card, via a digital
adapter ("Null Modem").

The CSC must redirect the wireless traffic to the local E1/T1 ports at the SIC
card. This is done by the ATM switching function of the CSC.

A local [***] port is used for local craft and NMS access.

The CSC-CMU-CRU group is subject to [***] redundancy, and they can be switched
with the [***] lines. The [***] lines switching is TBD.

The CMU is a rack mounted box. A future product release will allow to plug the
CMU directly to the CSS.

A co-located TMN adapter converts the l0BaseT SNMP traffic to CMIZE/Q3 traffic.

3.6     CENTRAL STATION RELEASE 1

The configuration of release 1 is depicted in Figure 3-1. It consists of the
following components:

[***]

[***]. The ASC card provides mass storage, synchronization and NMS
access. The ASC card will not be required in future releases that do not use the
Axis shelf.

A CSC card, Axis plug-in module, identical to the AirStar Access product, with 2
[***] Mbit/sec capacity. The CSC is further discussed below.

A CTU (Central terminal Unit), a rack mounted module for converting two BSC
channels to [***] [***] lines. The CTU is similar in function to two SAS units
in the Access product.

A CMU - a rack-mounted "[***]" including [***]-channel RF modem. In release 1
[***] channel is in use per CCS card, however the other channel is available foe
a second [***] or for the future [***] CSC.

The CRU is the same [***] GHz product as the BRU in the Access project. It uses
a [***] antenna to cover a sector or a corner of a square cell.

Each CSC has a [***] port for NMS access. Future releases will convert these
ports by extra hardware and software to a TMN interface.

A [***] interface runs through the ch-2 port of the CSC to the CMU and from the
CSC to the CTU, thus the two CSC cards can communicate both via the [***] and
they have control of the CMU and CRU for redundancy switching.

The main differences in release 2:

The CSC is replaced by an identical function that does not require an Axis shelf
and an ASC card. The new unit is rack mounted, has [***] and is called BUNI (for
Base-User Network Interface). The BUNI also includes a port for fast redundancy
switch using the direct port.

Subsequent BUNI and CMU releases will also support [***] QAM.

The CSC includes some functions that are not necessary for the feeder
application. Over time, these functions will be de-stuffed for cost reduction.
The main elements are:

CellMAC Controller for controlling the MAC air interface (including framing,
FEC, timing).

Request Grant Processor for coordinating the air interface activities.

ATM Cross connect for switching local traffic and user traffic.

A CPU, PCI interface and [***] interfaces.

While there will be several versions of the SIC card, the above \block diagram
depicts the typical implementation.

CellMAC ASIC controls the MAC layer, scrambling, REC and ATM conversion (AAL1
and AAL5).

A CPU control the system, running the VX-Works operating system, local
configuration, MAC management and the SNPM agent.

Four [***] or [***] (stuff options) provide the line interfaces.

Two serial ports provide a test port and a telemetry port controlling the radio.

The modem interface includes data/clock lines and a control bus.

3.9     ENVIRONMENTAL

See Table 3-3.

3.10    NMS

See Table 3-3. Italtel will provide a QAD board for NMS integration. [***]

3.11    EVOLUTION

The product will evolve in capacity, national standards, and frequency bands.

The evolutionary steps are:

The CSC release 1 is [***] channel [***]QAM for [***] MHz (ETSI) and [***] MHz
(FCC) channel spacing. Release 2 is [***] channel, [***] QAM [***] MHz (ETSI)
and [***] MHz (FCC). The CSC is changed to a rack mounted [***].

The CRU and TS release 1 are [***] GHz band. Future release is for [***] GHz
channel and US bands (TBD).

The CMU is a [***] [***] Pizza box, [***] QAM. It will evolve to a Dual [***]
QAM modem BMU card, and a SMU card (dual [***]) in release 2.

1.   PERIOD OF AGREEMENT

This agreement is entered into as of May 31, 1998 between Solectron California
Corporation whose principal place of business is located at 847 Gibraltar Drive
Milpitas, California 95035 (Supplier) and Netro Corporation whose principal
place of business is located at 3860 North First Street, San Jose, CA 95134
(Netro). This contract shall begin on the date of signing of the Agreement, and
shall terminate thirty-six (36) months from that date unless terminated or
renewed per other terms of the Agreement. Contract renewal discussions will
begin at least six (6) months in advance of the contract termination date. It is
the intent of the parties that this Agreement shall prevail over the terms and
conditions of any purchase order, acknowledgment form or other instrument.

2.   PRODUCTS, PRICES & QUANTITIES.

2.1  PRODUCTS TO BE PRODUCED. Supplier agrees to supply to Netro throughout the
term of this Agreement, any mix of the items listed in Appendix "A" at the
prices agreed to in writing by the parties. Other Products may be added to
Appendix "A" once Netro and Supplier have reached written agreement.

2.2  PRODUCT DEFINITION. At the start of this Agreement, Supplier shall produce
the Products defined in Appendix "A" exactly to the drawings, specifications,
and documentation provided by Netro and agreed to in writing by Supplier unless
otherwise approved in writing by Netro. Only the suppliers shown on the Approved
Vendor List ("AVL") provided by Netro shall be utilized for the initial
procurement of materials. Supplier shall have the right to submit revisions to
Netro to the AVL and Bill of Material ("BOM") so that cost reductions shall be
achieved. Such revisions may include, but not be limited to design changes,
manufacturing technology improvements, development of new vendors, etc. All such
changes submitted by Supplier shall be approved in writing by Netro, prior to
implementation of the changes and Netro shall have the unlimited right to use
such changes, in any way it deems appropriate and at its sole discretion.

2.3  COST REDUCTION. Supplier shall implement an ongoing cost reduction program
(including material and productivity improvements) that will target an
annualized cost reduction of a minimum of [***] per cent ([***]) per Quarter for
Appendix "A" Products. Each cost reduction year will start at the signing of the
Agreement and continue until the anniversary date of the Agreement, then a new
cost reduction year will start. Netro will support this cost reduction effort
and will work closely with Supplier to achieve the targeted results. Changes to
meet the cost reduction goals will be mutually agreed to in terms of
implementation timing, effect on inventories, value of the cost reduction,
overall total cost savings, etc. Supplier shall retain the savings of Supplier
generated cost reductions within the quarter that they occur and will be
reflected in the quoted Product costs at the quarterly progress review meeting,
then such savings shall revert fully to Netro. Cost reductions developed solely
by Netro shall be fully retained by Netro. Each cost reduction activity
associated with material or design changes will be authorized by a Netro
generated and approved Engineering Change Order (ECO). The ECO will document the
initiator of the cost reduction, i.e., Netro or Supplier, and the change in the
Product cost to Netro resulting from the cost reduction. Cost reductions may
include but not be limited to reductions in Supplier margins, labor rates,
overheads, G & A's, etc. as driven by efficiency improvements, volumes or total
revenues. At each quarterly progress review meeting, a summary of cost reduction
activities and results will be presented by Supplier.

information from time to time from Supplier and vice versa. These requirements
may be included as an Appendix to this Agreement or requested in writing from
Netro or Supplier.

4. PRODUCT ORDERING

4.1 FORECAST. Netro will provide a [***] rolling shipment forecast each month
and a [***] shipment forecast each quarter. These forecasts shall be by item
part number and shall include anticipated delivery date, quantity to be
delivered, etc. and are non-binding best estimates of Netro's future needs.
However, if Netro falls short of this goal by the end of the term of this
Agreement, or cancels this Agreement, there shall be no bill-backs or other
retroactive price increases associated with the shortfall or cancellation.

4.2 PURCHASE ORDERS. Netro's initial purchase order for each Product shall be
for sixty (60) days of Product shipments which will set forth the ordered
types, quantities & required delivery dates of the Products to be produced. Each
month, Netro will release an additional thirty (30) days of Product, which will
be, to the extent possible, based on the forecasts provided above. Upon receipt
and acceptance of Netro's purchase order or material release, Supplier will be
obligated to sell and deliver the Products in accordance with the quantities
and delivery dates specified by the purchase orders or releases. Purchase order
releases will be provided to Supplier by Netro within ten (10) working days
after the end of each calendar month.

4.3 QUANTITY & DELIVERY CHARGES. Purchase orders for existing Products can
deviate from forecast or purchase order as follows:

          a.   Within 30 Days - plus or minus [***]
          b.   Between 31 and 60 Days - plus or minus [***]
          c.   More than 60 Days - plus or minus [***]

where the total charge for the quarter is plus or minus [***] per cent [***].
Any change requested by Netro beyond the allowable increase/decrease shall be
handled by Supplier on a reasonable commercial efforts basis subject to material
availability, capacity availability and agreed upon Product testing
requirements. If the volume exceeds [***] Product units per month, Netro and
Supplier agree to review these percentages at the quarterly progress review
meetings and adjust them to then current business requirements. Should Netro
insist on keeping this high degree of flexibility for unit volumes exceeding
[***] per month the parties will negotiate in good faith a reasonable carrying
charge for such excess inventory.

From time to time, Netro may request Supplier to carry or have on order certain
strategic components, subassemblies, or assemblies (collectively "Strategic
Materials") at higher levels than required in this clause. In this case, Netro
would be responsible for the carrying cost of Strategic Materials.

facilities. Supplier will provide reasonable space for the source inspector.
Supplier will provide Netro five (5) working days advance notice of Product
availability for source inspection and Netro agrees to source inspect said
Products within five (5) working days after such notification. When Netro elects
to perform source inspection at Supplier's facility, final acceptance shall
occur at the time of source inspector's acceptance of Product, provided however,
that the mere review by Netro of performance data, test results and
manufacturing processes and consultation with Supplier's employees by Netro
regarding such information shall not be deemed to be a Source Inspection
hereunder. Netro may elect to inspect delivered Products one hundred per cent
(100%) or on a sampling basis. Any lot failing to meet the mutually agreed upon
sample inspection lot rejection criteria may be returned to Supplier for one
hundred per cent (100%) inspection, at Supplier's expense, if so desired by
Netro. Netro will notify Supplier of rejection of any Products in writing
within two (2) working days after rejection. Supplier may elect to have the
Products returned to them for evaluation, or with Netro's concurrence, have
Netro repair the Product at Supplier's pre-approved cost. Any Products returned
to Supplier shall be handled per Supplier's Returned Material Authorization
procedure. Products returned to Supplier for evaluation and/or repair shall be
repaired or replaced by Supplier within ten (10) working days of receipt unless
required by Netro to meet Netro's monthly shipment commitments. In that event,
the Supplier will utilize available resources, including finished goods
inventory, overtime labor, etc. to expedite and complete the timely delivery of
Products at Supplier's expense.

8. SHIPMENT & DELIVERY.

8.1 ON-TIME DELIVERY. Supplier agrees to deliver Products on-time per its
committed delivery dates as stated on Netro's Purchase Order and agreed to by
Suppliers acknowledgment of said Purchase Order. On-time delivery is defined to
be plus or minus [***] from the committed delivery dates. On-time delivery point
is Supplier's dock. The FOB point will be Supplier's facility. Shipping is to be
by normal transportation methods, unless otherwise requested by Netro. Netro, in
the future, may require Supplier to ship directly to end users of the Products.
These shipments will be FOB Supplier's facility.

8.2 EARLY/LATE DELIVERY. Early Delivery is defined as [***] in advance of
scheduled delivery date. Netro at its option can refuse to accept early delivery
and if Netro chooses to accept early delivery, such acceptance must be in
writing. Late delivery is defined as being [***] later than the scheduled and
acknowledged delivery date at the applicable dock as stated in the appropriate
purchase order. If Supplier fails to make deliveries at the specified time and
such failure is caused by Supplier, Supplier will, at no additional cost to
Netro, employ accelerated measures such as material expediting fees, premium
transportation costs, or labor overtime required to meet the specified delivery
schedule or minimize the lateness of deliveries. If despite such measures and in
the event late delivery is solely attributed to Supplier, Supplier shall, after
a  grace period of ten (10) business days, incur a liquidated damage fee for
late delivery of [***] of the Product selling price for each full week units are
late after the grace period. These liquidated damages shall be capped at [***]
of the price of the late units. Netro may terminate the Purchase Order (or this

MANUFACTURING AGREEMENT
- --------------------------------------------------------------------------------
10. TERMINATION.

Either party shall have the right to cancel this Agreement without cause by
providing ninety (90) days written notice to the other party. Supplier will be
entitled to reimbursement for reasonable costs associated with termination
without cause by Netro or with cause by Supplier (as provided in Section 13.4),
but shall not be entitled to reimbursement if this Agreement is canceled
without cause by the Supplier or with cause (as provided in Section 13.4) by
Netro. Reasonable costs may include the contract price of all finished Products
on hand, the cost of material inventory (including handling charges and value
add) whether in raw form or work in process, the cost of material on order
(including charges) which can not be canceled, and any vendor cancellation
charges incurred with respect to material canceled or returned to the vendor.
The Supplier will use reasonable commercial efforts to mitigate these
cancellation and restocking charges through negotiation with suppliers and
utilization of materials in Supplier's other customer's products. Netro shall
have the right to any or all material received by or paid for by Netro under
this clause. In the event of a termination request by Supplier without cause,
Netro shall receive no less than ninety (90) days written notice to place a last
buy for forecasted deliveries up to (6) months inclusive of the 90 days written
notice and Supplier will provide documentation for tooling and fixtures to Netro
as requested.

11. WARRANTY.

Supplier warrants that the units of Product supplied under this Agreement will
meet the mutually agreed upon specifications in effect at the time of
manufacture and be free from defects in Supplier supplied material and
workmanship for a period of [***] from the date of manufacture. Parts not
meeting the specifications shall be returned to Supplier for replacement, repair
or credit. Supplier will return all units determined by Supplier to be warranty
defectives within ten (10) working days of receipt. The repair work will be
warranted for a period of [***] from the date of repair or for the original
warranty date, whichever is longer. Repair of out of warranty returns will be
negotiated between Netro and Supplier. Supplier will provide corrective and
preventive action for all in warranty materials identified as not meeting
specifications. Replacement, repair or credit of warranty repairs constitutes
Netro's sole remedies against Supplier for breach of warranty claims. Out-of
Warranty Products returned to Supplier for repair shall be evaluated and the
cost to repair the unit determined. Within five (5) business days of receipt of
Product Supplier will notify Netro of the estimated repair cost and will await
written authorization from Netro before starting work. Out-of-warranty repairs
will be completed and returned to Netro or end customer within fifteen (15) days
of receipt of start work authorization subject to material availability.
Products that have been subjected to abuse, misuse, accident, alteration,
neglect or unauthorized repair will be handled the same as an Out-of-warranty
repair.

THE WARRANTIES CONTAINED IN THIS SECTION ARE IN LIEU OF, AND SUPPLIER EXPRESSLY
DISCLAIMS AND NETRO WAIVES ALL OTHER REPRESENTATIONS AND WARRANTIES, EXPRESS,
IMPLIED, STATUTORY OR ARISING BY COURSE OF DEALING OR PERFORMANCE, CUSTOM,
USAGE IN THE TRADE OR OTHERWISE, INCLUDING WITHOUT LIMITATION THE IMPLIED

                               APPENDIX B QUALITY

(A) Supplier commits to ensure that all manufacturing, and design operations,
    including any key sub-contractor, or contract manufacturing suppliers, which
    contribute to the design, development, production, delivery and service of
    material are ISO 9000 registered by an accredited Registrar by one year
    after first purchase order is placed by Netro.

(B) Supplier commits to having a continuous improvement program in place which
    will allow it to attain and maintain "acceptable" ratings (or equivalent) on
    all quality system elements as periodically performed by Netro. An
    "acceptable" element is defined as one where the quality system meets the
    "general intent" of the quality system and is fully deployed to maintain the
    quality system and product quality. No significant deficiencies encountered
    that would jeopardize the quality system, and product quality and/or
    reliability.

(C) Supplier commits to establish key quality control (qc) verification points
    throughout the manufacturing process. These verification points should be
    located in-process as well as after MATERIAL has completed all manufacturing
    operations. The scope of these qc verification points shall be validated
    through visual or mechanical inspections and/or tests, and with the use of
    statistically valid sampling plans, that MATERIAL conforms to Supplier's
    manufacturing, product and process specifications, standards of acceptable
    workmanship, as well as other specifications which may be provided by Netro.

      Material shall be considered defective if it fails to meet the warranty
      specifications under this Agreement (including performance and appearance
      Specifications) or if during customer testing, installation, or use, the
      MATERIAL fails to operate as expected or specified.

      If the analysis of a return is found to be within the specifications of
      this agreement (i.e., a no trouble found condition), then Supplier shall
      track these no trouble found conditions and notify Netro of said findings
      at a minimum of a monthly interval, so that appropriate investigative
      measures may be taken to determine the root cause.

(G)   If the return rate is found to exceed a mutually agreed to acceptable rate
      or repetitive occurrences are observed with regard to component level
      failures then the supplier shall provide a written Corrective Action
      Report to Netro, explaining in detail the nature of the problem detected,
      and the step(s) Supplier proposes to correct the problem. As part of the
      plan to correct the problem, it is agreed that the Supplier shall:

            a) Incorporate the remedy in affected MATERIAL.

            b) Ship all subsequent MATERIAL incorporating the required

                                   APPENDIX C

                               STATEMENT OF WORK

OBJECTIVE: Netro will help Solectron acquire high-frequency RF expertise, with
the goal of becoming proficient in manufacturing radio products within 6 to 9
months. Solectron will help Netro put processes in place that will facilitate
future product transitions, as well as prepare for volume ramp of Netro's
product line.

SCOPE OF WORK

Solectron shall make itself familiar with Netro's products, primarily by
residing on-site to learn and document processes and technology. The objective
is to fully understand the design, test and manufacturing of the Netro's product
line. Listed below are the major points that need to be addressed going forward.

1.  This phase will review the following areas:

    1.1  Netro's design, test and manufacturing process flow

    1.2  Netro's test plans and procedures, Failure diagnostics/analysis
         methodologies, cycle time, calibration procedure and cycle time, test
         cycle time, and yield data.

2.  ESS requirements (HALT, etc.)
    Solectron shall work with Netro to prepare and compile:
    2.1  Test plans
    2.2  Test Procedures
    2.3  Define failure criteria at the component, board and system level
    2.4  And provide/participate for the design inputs as a result of 2.1-2.3.

3.  ICT opportunities

STC shall work with Netro to determine which assemblies are candidates for ICT.
Netro to provide schematics for all assemblies quoted.

4.  Failure analysis/isolation/detection

    There shall be three levels of failure isolation/detection, based on
    criticality:
    4.1  Level three (board/box level failures that occur during normal
         manufacturing operations)
    4.2  Level two - component level failures which may be due to:
         4.2.1  Faulty/Bad component
         4.2.2  Design related failures (Derating factors, out of spec, etc.)
         4.2.3  Process related failures (IR reflow, shorts/opens, solder, etc.)
    4.3  Level one (Failure has been isolated to a component, cross sectioning
         may be required to determine the cause of the failure to be performed
         either at Solectron or at Solectron's supplier using Solectron's
         leverage)




                                       1
<PAGE>   22
5.   RF functional Test

Short term, Solectron will work with Netro to streamline current test process to
increase efficiency and throughput. Longer term, the focus would move towards:

     5.1  Cost/Trade off analysis on the level of automation
     5.2  Automation implementation based outcome of 5.1 above
     5.3  Increase test coverage at the box level
     5.4  Determine proper amount of time for testing

6.   Training methodology

     6.1  The Solectron project will work with Netro to understand their testing
          methodology and put forward a training plan for Solectron's operators.
     6.2  Based on the outcome in 6.1, adequate training for Solectron's
          operators/technicians/engineers will be provided.
     6.3  The Solectron project team will work to enhance the on-going RF
          training provided presently for the operators, technicians and
          engineers working at Solectron, to ensure a strong RF pool of
          resources to draw from in future.

7.   Hiring of RF engineers/technicians:

Due to increasing demand for manufacturing and testing RF products, Solectron is
in the process of recruiting additional RF/Microwave/Wireless engineers and
technicians. There are several openings within the Milpitas campus. The
Solectron Technical Center has solidly positioned its RF capabilities by
establishing several business relationships with RF consulting firms in US for
outsourcing of consulting engineering services if an when necessary. Solectron
is currently staffed for the manufacturing of PCB's from Netro, but will hire
(or transfer) resources for the radio production.

8.   Reliability

Solectron shall implement a reliability and qualification program plan in
collaboration with Netro. This plan will encompass both component and system
level testing in an attempt to help Netro with its design for reliability, yield
analysis and improvement, IQC, reduction/elimination of burn-in time, review/
audit of supplier's reliability, qualification and screening procedures,
utilization of derating factors, and worst case scenario analysis. Netro will
identify critical component list for Solectron.

9.   Source Inspection

Solectron to help perform source inspection, qualification, incoming test and
quality control for the critical RF components. Netro to identify critical
component list for Solectron.

the foregoing assignment by execution and delivery of such assignments,
confirmations or other written instruments as Purchaser may request. Purchaser,
its successors and assigns, shall have the right to obtain and hold in its own
name all copyright registrations and other evidence of rights that may be
available for such Specifications and Documentation. Manufacturer acknowledges
Purchaser's right to place the Specifications and Documentation in escrow in
Purchaser's cost, pursuant to the terms of Purchaser's agreements with customers
and other third parties. Notwithstanding the foregoing, in the event that
Manufacturer applies an improvement or invention to the Products which was not
(a) originally conceived of or reduced to practice in connection with a Product
of Purchaser, (b) created with the assistance of Purchaser personnel, materials
or information, OR (c) created pursuant to Section 5 hereof, such improvement or
invention shall be solely owned by Manufacturer, including without limitation,
patent, copyright, trademark, trade-secret, know-how, and other intellectual
property rights thereto.

4.      PURCHASE AND SALE OF PRODUCTS

a. Forecast. On or before the fifteenth (15th) day of each month, Purchaser
shall provide Manufacturer with a non-binding forecast setting forth, on a
Product by Product basis, Purchaser's requirements for the next six (6) calendar
months (the "Purchaser Forecast"). In addition, on each such date Purchaser will
provide Manufacturer with a good faith estimate of its expectations of Product
purchases by its third-party contractors. Manufacturer shall at all times
maintain sufficient inventory of components for the Products to ensure the
availability of Products to Purchaser and its third-party contractors consistent
with the forecasts provided as provided above. The Purchaser Forecast shall not
bind the Purchaser except as set forth in Section 4(b) below.

b. Orders. Purchaser agrees to place a binding purchase order for at least the
quantity of Products set forth on the latest two (2) months of the Purchaser
Forecast pursuant to standard purchase orders. Purchaser may also order
additional amounts from Manufacturer, pursuant to separate purchase orders
specifying the quantity of each Product to be purchased and the requested
delivery dates. Each purchase order hereunder shall be subject to the following
terms and conditions, notwithstanding anything contained in the purchase order
to the contrary.

(i) Acceptance and Rejection. Manufacturer will accept or reject purchase orders
from Purchaser in a written notice within five (5) working days of receipt
thereof, provided, however, that Manufacturer shall be required to accept any
purchase order that (A) does not increase the total amount to be purchased by
Purchaser beyond 25% of the total amount forecast during such period, and (B)
requests delivery no sooner than four (4) calendar weeks from the

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

date of such purchase order. Failure by Manufacturer to reject a purchase order
within the timeframe specified above shall be deemed to be acceptance of a
purchase order hereunder.

               Purchaser or its designees may elect to source inspect Products
and/or test data and results before delivery from Manufacturer. Manufacturer
will provide reasonable space for the source inspection. Manufacturer will
provide Purchaser with five (5) working days advance notice of Product
availability for source inspection and Purchaser agrees to source inspect said
Products within five (5) working days after such notification. When Purchaser
elects to perform source inspection at Manufacturer's facility, final acceptance
shall occur at the time of source inspector's written acceptance of Product. The
source inspector's written acceptance shall be made within five (5) working days
after such source inspection. If the source inspector fails to be available for
source inspection within the time frame established above, Manufacturer may ship
the Products and Purchaser will inspect the Products upon receipt as described
in the first paragraph hereof.

        (ii) Price. Following the qualification of Manufacturer for a given
Product, Manufacturer will quote a firm price for such Product, which will be
included in Appendix A to this Agreement and will be the price for a given
Product unless reduced as follows. Each such firm price quote will include a
bill of materials, cost of materials, cost of labor, profit margin and such
other detail as Purchaser shall reasonably request.

               Manufacturer will use its best efforts, with the assistance of
Purchaser, to implement an ongoing cost reduction program that will aim at a
price reduction to Purchaser of [***] percent ([***]) per annum, beginning once
the Manufacturer has produced more than [***] units of a Product. Manufacturer
agrees to update the Specifications and Documentation to reflect all such cost
reduction efforts and any such revised materials shall be "Specifications"
and/or "Documentation" for all purposes under this Agreement. Notwithstanding
the foregoing, no change will be made to the Specifications of or manufacturing
process for a Product without the prior written approval of Purchaser.

        (iii) Delivery. All purchase orders issued by Purchaser will be shipped
according to the schedule provided in the applicable purchase order. Deliveries
will be marked as instructed by the party placing such order, including without
limitation, with bar code labels as specified by Purchaser or its third party
contractors from time to time, and will include all relevant test data for such
shipment. All shipments of Products are FOB Manufacturer's factory location with
method of shipment and insurance specified by and paid for by the party placing
the order. If a Product is not available for more than ten (10) working days
from the originally schedule delivery date, Manufacturer shall accrue a late fee
of [***] of the selling price for such Product(s) which is (are) delayed in such
order for each day that such order is delayed beyond such ten (10) working day
period, up to a maximum of [***]. Notwithstanding the foregoing, such penalties
shall not apply where the delays in shipment are as a result of design defects
or Purchaser's negligence.

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

           (iv) Rescheduling. A purchase order may be rescheduled, prior to
fifteen (15) working days before the scheduled delivery date for such order. If
a purchase order is rescheduled for more than thirty (30) calendar days from the
originally scheduled delivery date, Purchaser shall accrue a rescheduling charge
of [***] of the selling price for such rescheduled purchase order for each
thirty (30) day period that such rescheduling of a delivery date is delayed
beyond such thirty (30) day period up to a maximum of [***]. If a rescheduling
of a delivery date is delayed beyond [***], Manufacturer shall have the right to
deliver the Products for such purchase order on the one hundred-and-eightieth
day from the originally scheduled delivery date.

        (v) Cancellation. In the event that Purchaser cancels any purchase
order, Purchaser shall compensate Manufacturer for the reasonable, actual,
out-of-pocket expenses incurred by Manufacturer in acquiring components and
manufacturing the Products subject to such order. Manufacturer will use its best
efforts to mitigate such costs however, in the event that Purchaser is required
to compensate Manufacturer under this Section, Purchaser shall be entitled to
take title over all inventory, components and Products for which it delivers
compensation hereunder.

        (vi) Payment. Payment is due and payable fifty (50) calendar days from
the date of issuance of the invoice or shipment of the Products, whichever is
later (the "Payment Date"). Within ten (10) business days after notice by
Manufacturer of its acceptance of a purchase order, Purchaser will establish an
irrevocable letter of credit with a U.S. Bank in favor of the Manufacturer in
the amount of such purchase order (each an "LC"). Each LC shall provide that the
Manufacturer may draw upon the LC on the Payment Date, upon presentation of a
letter, certified by Manufacturer, as to the shipment of the Products and the
invoice and/or shipment date, together with such other documentation and
evidence of shipment as is reasonably established in such LC.

        (vii) Electronic Data Interchange. Manufacturer and Purchaser will
jointly implement an Electronic Data Interchange ("EDI") system that is
compliant with the EDI requirements of Purchaser's customers in a mutually
agreed to scope and timetable.

        (viii) Semi-Annual Review of Prices. Beginning on the date [***] from
the date of this Agreement, and every [***] thereafter, the parties will meet to
discuss in good faith revisions to the pricing and payment terms set forth in
this Section 4(b), in order to reflect competitive pressures and other
then-current market conditions.

c. Acceptance and Rejection of Deliveries. The basic acceptance criteria for
Products shall be conformance to the Specifications by Purchaser. The Purchaser,
or its third-party contractors will accept or reject deliveries of the Products
within twenty (20) working days of receipt of such Products. Such party may
elect to reject Products individually or reject lots on the basis of sample
inspections as described on Appendix A. Any Product (or lot of Products based on
a sample) which fails to meet the Specifications due to the fault of
Manufacturer, will be replaced or repaired by Manufacturer. All such Products
shall be tracked by Manufacturer's RMA system. Manufacturer shall provide
monthly reports on the status of all RMAs. If the recipient

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

of an order does not provide Manufacturer such notice within the twenty (20)
working day period, the Product will be presumed to have been accepted, and any
defective Products will be dealt with thereafter as warranty claims.

d. Purchases from Purchaser. Manufacturer will purchase certain components and
inventory from Purchaser on terms and conditions mutually agreeable to the
parties and pursuant to purchase orders distinct from those under this
Agreement.

5.      ENGINEERING SERVICES

a. Identification of Services. Manufacturer agrees to undertake and complete
certain manufacturing engineering tasks for Purchaser. Purchaser has described
such services to Manufacturer in detail and Manufacturer has provided purchaser
with a firm price quote for such services, both of which are attached hereto as
Appendix D. It is the parties intention that Purchaser will compensate
Manufacturer for these services proportionately to reflect the timely
achievement of milestones by Manufacturer and the value of interim milestones to
Purchaser. Therefore, within ten (10) working days after the Effective Date,
Purchaser and Manufacturer will mutually agree upon an update to Appendix D,
which will provide for the same services to be provided by Manufacturer to
Purchaser at the same price quoted by Manufacturer, but will also list key
interim milestones for such services, delivery dates for each such milestone and
payment amounts for each such milestone. As the parties identify additional
manufacturing engineering tasks with respect to existing or newly added Products
the parties will, by mutual agreement, update Appendix D in writing. The
products of the efforts of the tasks referred to on Appendix D are referred to
herein as the "Deliverables".

b. Acceptance and Rejection of Deliverables. Upon delivery of any Deliverables,
Purchaser will test, review and otherwise evaluate such Deliverables to
determine whether such Deliverables warrant modifications to the Specifications,
Documentation or manufacturing process for a Product. Within thirty (30)
calendar days of delivery of the Deliverables, Purchaser shall provide
Manufacturer with written notice of acceptance or rejection of such
Deliverables. In the event Purchaser rejects such Deliverables for cause (i.e.,
failure to comply with the specifications for such Deliverable), Purchaser may,
at its option extend the period for delivery of such Deliverable on the basis of
the originally agreed to compensation or terminate the project for such
Deliverable with no further liability to Manufacturer. If Purchaser rejects such
Deliverable other than for cause, Manufacturer shall nonetheless be entitled to
receive the compensation as set forth in subsection (c) below. If Purchaser
accepts such Deliverable, Manufacturer and Purchaser will work together to
implement such changes as are necessitated to the Specifications, Documentation
and other materials and Manufacturer shall be entitled to receive compensation
as set forth in subsection (c) below.

c. Ownership of Deliverables. Manufacturer understands and agrees that the work
to performed by it for Purchaser pursuant to this Agreement shall be considered
"Work Made for Hire" as that term is defined in Title 17, United States Code,
Section 201; Purchaser shall own all right, title and interest in the
Deliverables developed by Manufacturer. If, for any reason, the

<PAGE>   8

NETRO
THE WIRELESS ATM COMPANY                                          EXECUTION COPY
- --------------------------------------------------------------------------------

Works Made for Hire rule is found not be applicable to this Agreement,
Manufacturer hereby assigns all of its right, title and interest in the
Deliverables, including, without limitation, all patent rights, copyrights,
trade secrets to Purchaser. Manufacturer agrees to cooperate with Purchaser and
to execute all documents necessary to effectuate and perfect Purchaser's
ownership of and rights to the Deliverables.

d. Compensation for Deliverables. In consideration for any engineering services
provided hereunder Purchaser will issue securities to Manufacturer (or a
wholly-owned subsidiary of Manufacturer) as follows. Upon the achievement of
each milestone for which Manufacturer is entitled to compensation pursuant to
Appendix D, Purchaser will issue to Manufacturer (or a wholly-owned subsidiary
of Manufacturer) that number of shares of the Purchaser's then most recently
issued series of Preferred Stock as is determined by dividing the dollar amount
specified for the achievement of such milestone on Appendix D by the price per
share at which shares of such series of Preferred Stock were most recently
issued. Notwithstanding the foregoing, if Purchaser effects an initial public
offering of Common Stock, then following such offering Purchaser may, at its
election, decide to compensate Manufacturer in cash, or such other mutually
agreeable form of consideration, for any services provided on or after the
effective date of such offering.

d. Termination of Projects. Purchaser may cancel a project for cause under this
Section, without any further liability to Manufacturer, if Manufacturer has not
delivered a Deliverable or other significant intermediate work product within
thirty (30) working days of the mutually agreed scheduled delivery date, or for
other material failures of Manufacturer in connection with such project.
Purchaser may also cancel a project for convenience under this Section at any
time, provided however, that if Purchaser cancels a project for convenience, and
the securities delivered by Purchaser as of such cancellation reflect, a
different percentage of the total securities originally planned to be issued for
such project than the percentage of work completed by Manufacturer as of such
date, then the party to whom such benefit has accrued will provide the other
party with cash compensation or will return or grant, as appropriate, securities
to the other party, to offset such differential compensation.

e. Additional Representations. With respect to any securities issued hereunder,
Manufacturer hereby represents and warrants, and agrees to represent and warrant
at the time such securities are issued, as follows: (i) that Manufacturer has
had access to and is familiar with information concerning the Purchaser's
business, affairs, financial condition, and current prospects; (ii) that any
such securities are being acquired for its own account, not as a nominee or
agent, and not with a view to or in connection with the sale or distribution of
any part thereof; (iii) that Manufacturer understands that such securities will
not be registered under the Securities Act of 1933, and (iv) that the issuance
of such securities does not conflict with the laws of the jurisdiction in which
Manufacturer is organized. The Manufacturer further agrees that, in connection
with the initial registration of the Purchaser's securities that, upon request
of the Purchaser or the underwriters managing any underwritten initial public
offering of the Purchaser's securities, not to sell, make any short sale of,
loan, grant any option for the purchase of, or otherwise dispose of any
securities of the Purchaser (other than those included in the

registration) without the prior written consent of the Purchaser or such
underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days from the effective date of such registration) as may
be requested by the Purchaser or such managing underwriters.

6.      WARRANTY

Manufacturer warrants all Products sold under this Agreement to comply with the
Specifications and be free from defects in material and workmanship under normal
and proper use for a period of [***] from the latest of the issuance date of the
invoice of the purchase order, the shipment date for such Products and the
acceptance date for such Products.

THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES EXPRESSED, IMPLIED, OR
STATUTORY, INCLUDING WARRANTY OF MERCHANTABILITY.

Within the stated warranty period, Manufacturer will repair or replace, at its
option, any Product which is returned to its plant, provided inspection and
examination discloses to Manufacturer's reasonable satisfaction that (a) the
reported defects are within the warranty coverage, (b) the Product has not been
tampered with, or (c) the Product has not been damaged due to misuse, improper
storage or maintenance, negligence or accident. Purchaser will bear the cost of
shipping such defective Products to Manufacturer, and if Manufacturer is
required to repair or replace such Products, Manufacturer will return the
warranty repaired Product shipping via the same type of service originally used
to ship the failed Product to the recipient at Manufacturer's cost.

Any such returned or repaired item shall have a full [***] warranty beginning on
the date that such repaired or replaced Products are received by the Purchaser
or the Purchaser's customer. Manufacturer shall provide repaired or replaced
Products to the party ordering such products within fifteen (15) working days of
receiving such defective products.

THE FOREGOING CONSTITUTES THE PURCHASER'S SOLE AND EXCLUSIVE REMEDY AND IS IN
LIEU OF ANY AND ALL REMEDIES WHICH MAY BE AVAILABLE TO THE PURCHASER.

7.      Term

(including the deemed value of any engineering services provided hereunder)
during calendar year 2001 is greater than or equal to the greater of (A) [***]
and (B) [***] of Purchaser's Requirement of Products during such period;
Manufacturer and its affiliates agree that they will not directly or indirectly
provide products or services (excluding stand-alone, receive-only Low Noise
Block down converters for broadcast television services in the consumer
marketplace which are not designed to be integrated into the broad-band
point-to-multipoint microwave radios of any third party) to any third party,
including any affiliate of Manufacturer, with the effect of aiding the design or
manufacture of non-satellite, broad-band point-to-multipoint microwave radios in
the 10 to 42 GHz frequencies to a party other than the Purchaser.
Notwithstanding the foregoing, neither the dollar volume nor the percentage
purchase requirements for the maintenance will be necessary for the maintenance
of exclusivity if (1) Manufacturer has not qualified to release the Products
listed on Appendix E hereto within the timeframes listed thereon, or (2)
Manufacturer is failing to provide Products to Purchaser in accordance with the
delivery and quality requirements set forth in this Agreement and the
Documentation.

b. For purposes of measuring the minimum dollar requirements of Section 14(a)
above, up to an aggregate of [***] worth of purchase orders and engineering
services requests placed prior to the end of a period, but which are not to be
delivered until subsequent periods may, at Purchaser's election, be included in
measuring such minimum quantities, provided that if such amounts are so included
in a period, such amounts will not be included in any subsequent periods. For
purposes of measuring the minimum percentage requirements described in Section
14(a) above, the numerator of such fraction will be the monetary value of all
cash, securities and other compensation (including for components and
engineering services) delivered to Manufacturer by Purchaser or its third party
contractors hereunder and the denominator of such fraction will be the
Purchaser's Requirement for Products. The term "Requirement for Products" shall
mean the dollar value (as measured by the price from Manufacturer to Purchaser)
of complete radios purchased by Purchaser from any source.

c. In the event that Manufacturer's quoted prices are not comparable to those
available to Purchaser from other parties on similar terms and conditions,
Manufacturer will work together with Purchaser in good faith to reach a mutually
acceptable prices.

15.     PRODUCT CHANGES

Manufacturer understands and agrees that Purchaser from time to time may make
changes to the design and/or Specifications on any Product involved with this
Agreement. Changes will be documented and provided to Manufacturer via
Engineering Change Orders ("ECOs"). Each ECO will specify an effective date for
the change. Upon receipt of an ECO, Manufacturer shall review it and provide a
written response to Purchaser within five (5) working days stating any impact to
schedule or price. Manufacturer shall not implement any ECO which delays any
delivery schedule or increases price to the Purchaser without first obtaining
written authorization from Purchaser. Upon adoption of any ECO that has a
material impact on the price for a Product, Manufacturer will requote a firm
price for such Product in accordance with the

                                     [***]





The associated channel plan for the lower half of the band is listed in Table
2-1: ETSI [***] GHz Band [***] MHz Channel Plan. The table assumes that base
station uses the lower duplex frequency for transmit, although this does not
need to be the case. In some regions, the upper half of the band may be also
used, which is not illustrated here.

The ETSI [***]GHz band is divided into four bands each corresponding to a unique
radio unit model:

- -   Band [***] (downstream [***]): [***]GHz

- -   Band [***] (downstream [***]): [***]GHz

- -   Band [***] (upstream [***]): [***]GHz

- -   Band [***] (upstream [***]): [***]GHz

With Release 2, the AirStar system supports the [***] [***] GHz frequency plan
in the range [***]GHz, with a T/R spacing of [***]MHz and [***]MHz of step size.
The system will be capable of supporting [***] MHz or [***] MHz channels. The
associated channel plans for each of the channels are listed below. The AirStar
system is configured that the [***] transmit, higher duplex frequency is used
for Base Station receive. Vice verse for Subscriber terminals. The center
frequencies are in Table 2-2: [***] [***] GHz Channel Plan.

The values in Figure 2-2 - Bit Error Ratio [***] are based on extensive forward
error correction. As stated earlier the AirStar system uses [***], which is used
in the upstream transmission. Without [***], the [***] effect could be
disastrous. The analysis below refers to the upstream direction because it is

FEC overhead than the downstream direction. In the downstream [***] thus the
error performance is slightly better.

The degradation for [***] and [***] is tolerable because these values are well
within the link rain-fade margins. One view is that these are lost margins that
affect the link availability for subscriber terminals located in an interference
zone. But this view is too pessimistic.) [***] in linear unit's increases nearly
exponentially with distance. Therefore, in a [***] the interference source is
attenuated much more than the local source and [***] is lost.

At [***] the degradation is [***]. Therefore, a suitable frequency reuse scheme
will exclude coverage for areas with CIR below [***].

2.1.3. Frequency Reuse Assumptions

 1. The base stations use directional (sectorial) antennas with front-to-back
    ratio of at lease [***] dB, antenna pattern per ETSI specs (worst case).

 2. The subscriber terminals use directional antennas with front-to-back ratio
    of at least [***] dB.

 3. Each sector transmits in [***]. If [***] are aggregated in one sector, they
    are considered one frequency band for this analysis. Specifically, if four
    [***] MHz channels are in use, a [***] reuse scheme allows to group channels
    [***] and channels [***].

 4. Cross polarization is not included. This degree of freedom is additional to
    this analysis and can be added to [***], however horizontal polarization
    will have a [***] then vertical polarization caused by [***].

 5. The transmission if full duplex, Frequency [***]. All base stations transmit
    in the same frequency band.

 6. [***] AM modulation with strong FEC, such as BCH, [***] block.

 7. All terminals have line of sight to their base station.

 8. The area is a perfect plane where all base stations are visible (a worst
    case for interference).

 9. Any receiver can reject adjacent channels to a negligible interference. A
    [***] dB rejection is sufficient for most situations discussed below.

10. Free space attenuation law (Inverse Square of distance).

2.1.4 Two-Frequency Arrangement

A [***] arrangement can be assembled by a square cell shape or by hexagonal
shape. An example of a square arrangement is shown in Figure 2-3 -
Two-[***] reuse scheme.

2.1.5   TWO-FREQUENCY ARRANGEMENT COVERAGE

Based on the assumptions above and the AirStar system elements analysis of
coverage of a two-frequency square pattern has shown that about [***] of
subscribers can have good CIR with the [***] mm subscriber antenna. A large,
[***]mm antenna increases CIRlimited coverage to virtually [***]. This
performance is due to the following key enabling features.

- -       Interference-tolerant [***]QAM modulation

- -       Directional subscriber terminal antennas

- -       Sector antennas width with fast roll-off

- -       A special square-zone reuse geometry

The BRU and BMM IF interfaces are [***] Ohm TNC connectors. The BRU has an AGC
circuit on the IF interface to normalize the IF signals and overcome cable loss
due to varying lengths. Based on the cable AGC dynamic range, the IF cable type
can be employed based on the length requirement, for example LMR240 for less
than [***] meter and LMR400 for less than [***] meters.

Use only coaxial cable that meets the specifications in the Table below.

                                     [***]

An undamaged, unconnected coaxial cable should have a very high resistance
between center and ground. Cables reading less than 10MOhms should be carefully
inspected for water ingress or connector corrosion.

                                     [***]

3.2     SUBSCRIBER RADIO UNIT (SRU)

The SRU is a compact outdoor unit, which includes radio frequency (RF)
transmitter and receiver, as well as an integral antenna. For certain
applications an optional non-integral antennae can be used to increase the link
performance. The SRU utilizes a frequency diplexer, which allows transmitter and
receiver to share the same antenna unit.

The main function of an SRU is to provide a link to the BRU and to interface
with SAS at an intermediate frequency (IF).

For the [***]GHz system the mechanical interface is a one bolt attachment to the
SRU support cradle. The SRU cradle mounts to the outside wall or other mounting
surface at the subscriber premises. The mounting is intended to be low cost and
simple to install in common with a high volume subscriber application. Panning
in both azimuth and elevation is catered for, with a simple locking mechanism.

3.2.4.3 NON-INTEGRAL [***] GHZ ANTENNA MOUNT

The antenna is connected to a pole mount and the SRU is connected to the
antenna. This allows the radio transceiver to be removed without the need to
realign the antenna. The mounting system uses a waveguide flange and quick
release mounts, as is standard in the point to point area.

3.2.5   IF INTERFACE

The SAS-SRU IF interface is identical to the BRU-BMM IF interface.

                           QUALITY STANDARDS AND REPORTS

(A)   Manufacturer hereby represents and warrants that it is, and will continue
      to be ISO 9000 registered and commits to ensure that all sub-contractors
      or contract manufacturing manufacturers, which contribute to the design,
      development, production, delivery and service of material will become ISO
      9000 registered by an accredited Registrar within eighteen (18) months
      after first purchase order is placed by Purchaser.

(B)   Manufacturer commits to having a continuous improvement program in place
      which will allow it to attain and maintain "acceptable" ratings (or
      equivalent) on all quality system elements as periodically performed by
      Purchaser. An "acceptable" element is defined as one where the quality
      system meets the "general intent" of the quality system and is fully
      deployed to maintain the quality system and product quality. No
      significant deficiencies encountered that would jeopardize the quality
      system, and product quality and/or reliability.

(C)   Manufacturer commits to establish key quality control ("QC") verification
      points throughout the manufacturing process. These verification points
      should be located in-process as well as after material has completed all
      manufacturing operations. The scope of these QC verification points shall
      be validated through visual or mechanical inspections and/or tests, and
      with the use of statistically valid sampling plans, that material conforms
      to Manufacturer's manufacturing, product and process specifications,
      standards of acceptable workmanship, as well as other specification's
      which may be provided by Purchaser. Purchaser reserves the right to review
      these QC points and make suggestions for improvement. Manufacturer commits
      to address these suggestions through the implementation of appropriate
      corrective actions.

(D)   Manufacturer commits to establish an end of the line Quality Assurance
      product audit on material by three (3) months after first purchase order.
      The focus of this audit shall be to replicate user application of material
      as specified by Purchaser's customer. Test and examination of material
      under the quality audit shall be at a system level, and shall include but
      is not limited to:

      a)   Exercising said material over the full spectrum of temperature ranges
           over which material is designed to operate.

      b)   Full operation of material over a period of time not less than 72
           hours.

      c)   A system for continuous monitoring of all primary product functions
           and fault detection of the material while under this test.

      Manufacturer shall continuously review customer return data to ensure that
      the scope of the product quality assurance audit function includes the
      requirement(s)/condition(s) under which the return failed.

      Manufacturer shall perform a detailed failure mode analysis of all
      material found defective through the quality assurance audit in line with
      the requirements and process outlined in paragraph F.

      Manufacturer agrees to provide to Purchaser on a monthly basis, results of
      the quality assurance product audit in a format specified by Purchaser.

(E)   Manufacturer commits to establishing a program of tracking monthly,
      quarterly, and annual return rates for the product manufactured under this
      contract. The Manufacturer agrees to update and report on returns on a
      quarterly basis to Purchaser.

(F)   Manufacturer commits to establishing a system for tracking and analysis
      all material returned by Purchaser to it, as well as any material failures
      which occur through Purchaser's end of the line quality assurance audit.
      For all material in the above two categories, Manufacturer shall perform a
      failure mode analysis, which at a minimum will be down to the component
      level. Component level failure modes will be recorded, and failed
      components found defective will be accumulated for the purpose of
      determining repetitive occurrences.

      Material shall be considered defective if it fails to meet the warranty
      specifications under this Agreement (including performance and appearance
      Specifications) or if during customer testing, installation, or use, the
      material fails to operate as expected or specified.

      If the analysis of a return is found to be within the specifications of
      this agreement (i.e., a no trouble found condition), then Manufacturer
      shall track these no trouble found conditions and notify Purchaser of said
      findings at a minimum of a monthly interval, so that appropriate
      investigative measures may be taken to determine the root cause.

(G)   If the return rate is found to exceed a mutually agreed to acceptable rate
      or repetitive occurrences are observed with regard to component level
      failures then the Manufacturer shall provide a written Corrective Action
      Report to Purchaser, explaining in detail the nature of the problem
      detected, and the step(s) Manufacturer proposes to correct the problem. As
      part of the plan to correct the problem, it is agreed that the
      Manufacturer shall:

      a)   Incorporate the remedy in affected material.

      b)   Ship all subsequent material incorporating the required modification
           correcting the problem at no additional charge to Purchaser; and

      c)   Create a mutually agreed to plan to address the scope of correction
           and the proper course of actions to be taken by Manufacturer and
           Purchaser.

      Manufacturer and Purchaser shall mutually agree in writing as to the
      implementation schedule of the corrective action plan. Manufacturer agrees
      to use its best efforts to implement the plan in accordance with the
      agreed upon schedule. It is also agreed that

      Purchaser shall be entitled to postpone at no charge to Purchaser, further
      deliveries of orders until such time as the remedy is implemented
      consistent with this Article.

(H)   As part of a program of continuous improvement, Manufacturer agrees to
      establish annually, improvement goals for a series of key quality
      objectives. These goals should include, but are not limited to a) customer
      return rates b) Quality Assurance product quality audit defect rates, c)
      final system test yields. Manufacturer agrees to track these goals on a
      monthly basis, and to commit the resources necessary for the attainment of

NOTES:

Completion of the project definition means a resource plan is completed and
agreed upon in writing by both parties.

The units are to be tested against a mutually agreed written test plan. This
test plan to be prepared and finalized ahead of the delivery of the units to
prevent the qualification from being gated by this activity.

The units described as "pilot" are the units which are candidates to become the
"beta" deliverables from Netro under its gate process. They are intended to be a
"production" quality but to be built from early product documentation. These
designs are intended to migrate to "limited availability" and then "general
availability" without significant redesign.

The last milestone for each frequency marks the point at which the
responsibility for the project is transferred from the Engineering to the
Manufacturing organization in each company.

                                  OEM AGREEMENT

                                (Cisco as Seller)

This OEM Agreement (the "Agreement") is made as of the 7th of December, 1998
(the "Effective Date") by and between Cisco Systems, Inc., a California
corporation, having principal offices at 170 West Tasman Drive, San Jose,
California 95134-1706 ("Cisco") and Netro Corporation, a California corporation
having its principal place of business at 3860 North First Street, San Jose,
California 95134 ("Netro").

                                    RECITALS

      A. Netro has been purchasing from Cisco the Cisco MGX 8220 shelves and
associated products, software and firmware by means of purchase orders over the
past several months. These shelves have been, in turn, integrated with Netro's
Base Station Controller boards and resold to third parties as a part of the
"AirStar" wireless communications systems developed by Netro.

      B. Netro is developing an independent solution, which will permit it to
sell its systems without relying on the Cisco MGX 8220 shelves; however, Netro
requires on-going access to the Cisco MGX 8220 shelves for resale during this
development period. Cisco desires to sell the Cisco MGX 8220 shelves and
associated products, software and firmware to Netro during the development
period to enable Netro to transition to an independent solution.

      C. Netro also desires access to certain Cisco technology and intellectual
property in order to transition to an independent solution. Cisco desires to
license such technology to Netro under a separate license agreement that will be
executed contemporaneously with this Agreement (the "Technology Agreement").

      D. The parties now desire to enter into an agreement pursuant to which
Cisco agrees to sell and Netro agrees to purchase a limited number of the
Products under the terms and conditions set forth herein.

      NOW, therefore, in consideration of the terms and conditions of this
Agreement, the parties agree as follows:

1.    DEFINITIONS

      Terms used in this Agreement not otherwise defined elsewhere shall have
the meanings ascribed to them below.

standard lead time, which shall be thirty (30) days unless Cisco notifies Netro
to the contrary. Cisco shall use reasonable efforts to notify Netro of the
acceptance or rejection of a purchase order within ten (10) days of receipt of
the purchase order, however, no purchase order will be binding upon Cisco until
accepted by Cisco in writing. Partial shipment of an order will not constitute
acceptance of an entire order. Cisco shall use reasonable efforts to ship
Products covered by a Purchase Order so as to ensure receipt prior to the
corresponding confirmed delivery date. Netro's sole and exclusive remedy if
Cisco fails to so ship such Products at that time shall be to require Cisco to
reschedule delivery within fourteen (14) days of the original scheduled delivery
date.

shall deliver to Cisco its good faith, non-binding forecast of Netro's estimated
demand for the during the first two (2) calendar quarter of the Purchase Period.
Netro shall deliver to Cisco a good faith, non-binding forecast for each
additional calendar quarter at least sixty (60) days prior to the commencement
of such calendar quarter. The submission of a forecast shall not require Netro
to make any purchases and does not constitute an order.

      4.4 Cancellation. Netro may cancel, postpone or reschedule delivery of the
Products ordered pursuant to Purchase Orders upon notice to Cisco prior to
scheduled delivery as set forth below. Any cancellation of delivery of the
Products less than ninety (90) days prior to the scheduled delivery date shall
be subject to a cancellation charge to Netro based on the table below. A
postponement or postponements which are to a date more than thirty (30) days
after the original scheduled delivery date and which are made at Netro's request
may at Cisco's option by written notice to Netro be treated as a cancellation
pursuant to this Section 4.4. The provisions of this Section 4.4 shall survive
any termination of this Agreement with respect to Purchase Orders issued prior
to such termination.

authorized officer of both parties.

      17.8 Waiver. Except as specifically provided in a waiver signed by a duly
authorized officer of the party seeking enforcement, the failure to enforce or
the waiver of any term of this Agreement shall not constitute the waiver of such
term at any time or in any circumstance and shall not give rise to any

for convenience of reference only and shall not alter or affect the terms, or
interpretation, of this Agreement.

      17.10 Force Majeure. Neither Cisco nor Netro shall be liable to the other

      17.13 Mutual Release.

      (a) Netro's Release. In consideration of the rights and licenses granted
to Netro under this Agreement and the Technology Agreement, Netro hereby
releases and forever discharges Cisco and its direct or indirect assigns,
parents, predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants, successors and
assigns, past and present, and each of them, from any and all claims, liens,
demands, causes of action, obligations,


                                      -15-
<PAGE>   16
damages and liabilities, known or unknown, that Netro has had in the past, or
now has, or may have in the future against Cisco, or any other persons or
entities, arising directly or indirectly out of or related in any way to any
prior business dealings, negotiations, discussions or agreements between parties
or their predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants successors and
assigns, past and present. Netro agrees and covenants that it will not ever
institute any suit or action at law or in equity against Cisco by reason of any
claims or causes of action described above.

      (b) Netro's Waiver of Unknown Claims. Netro expressly understands and
acknowledges that it is possible that unknown losses or claims exist or that
present losses may have been underestimated in amount or severity, and that it
explicitly took that into consideration in entering into this Agreement. With
knowledge of the possibility of unknown claims, a portion of the consideration
provided for herein was given in exchange for a full accord, satisfaction and
discharge of all such claims. Consequently, Netro acknowledges and agrees that
it is fully aware of and hereby waives all rights or benefits which it may now
or in the future have under the provisions of California Civil Code Section
1542, which section has been explained fully by counsel and which provides as
follows:

A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with debtor.

      (c) Cisco's Release. Cisco hereby releases and forever discharges Netro
and its direct or indirect assigns, parents, predecessors, successors,
subsidiaries or affiliated corporations or business entities, past and present,
as well as its directors, officers, partners, shareholders, agents, employees,
attorneys, servants successors and assigns, past and present, and each of them,
from any and all claims, liens, demands, causes of action, obligations, damages
and liabilities, known or unknown, that Cisco has had in the past, or now has,
or may have in the future against Netro, or any other persons or entities,
arising directly or indirectly out of or related in any way to any prior
business dealings, negotiations, discussions or agreements between parties or
their predecessors, successors, subsidiaries or affiliated corporations or
business entities, past and present, as well as its directors, officers,
partners, shareholders, agents, employees, attorneys, servants successors and
assigns, past and present. Cisco agrees and covenants that it will not ever
institute any suit or action at law or in equity against Netro by reason of any
claims or causes of action described above.

      (d) Cisco's Waiver of Unknown Claims. Cisco expressly understands and
acknowledges that it is possible that unknown losses or claims exist or that
present losses may have been underestimated in amount or severity, and that it
explicitly took that into consideration in entering into this Agreement. With
knowledge of the possibility of unknown claims, a portion of the consideration
provided for herein was given in exchange for a full accord, satisfaction and
discharge of all such claims. Consequently, Cisco acknowledges and agrees that
it is fully aware of and hereby waives all rights or benefits which it may now
or in the future have under the


                                      -16-

provisions of California Civil Code Section 1542, which section has been
explained fully by counsel and which provides as follows:

A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with debtor.

      (e) Limitation. The parties acknowledge and agree that the mutual releases
and waivers contained in Sections 17.13(a), (b), (c) and (d) above do not apply
to claims, liens, demands, causes of action, obligations, damages and
liabilities arising out of, or relating to, (1) any purchase orders for the
Products placed Netro and accepted by Cisco prior to the Effective Date of this
Agreement or (2) a breach of the terms and conditions of this Agreement or the
Technology Agreement.

      17.14 Entire Agreement. The Technology Agreement and this Agreement,
including any Appendices, schedules and tables attached hereto which either have
been specifically referred to herein or have been initialed by the parties,
constitute the entire agreement between the parties with respect to the subject
matter. This Agreement supersedes all prior discussions, understandings,
agreements and representations with respect to the subject matter hereof.

      17.15 Relationship of the Parties. The parties are independent contractors
under this Agreement and no other relationship is intended, including a
partnership, franchise, joint venture, agency, employer/employee, fiduciary,
master/servant relationship, or other special relationship. Neither party shall
act in a manner which expresses or implies a relationship other than that of
independent contractor, nor bind the other party. The parties acknowledge and
agree that any breach of the foregoing sentence shall be deemed a material
breach of this Agreement.

      IN WITNESS WHEREOF, the parties have executed this Agreement as of the day
and year first above written.

                              EMPLOYMENT AGREEMENT

        This Employment Agreement (the "Agreement") is entered into as of March
__, 1995 between Netro Corporation, a California corporation (the "Company"),
and Gideon Ben-Efraim, an individual ("Employee"). This Agreement shall have an
effective date (the "Effective Date") of December 1, 1994.

        In consideration of the promises and the terms and conditions set forth
in this Agreement, the parties agree as follows:

        1.      POSITION. During the term of this Agreement, the Company will
employ Employee, and Employee will serve the Company, as its Chairman of the
Board of Directors and Chief Executive Officer and President. In the event that
another individual is hired to serve as Chief Executive Officer of the Company
(following consultation with Employee) in the future, Employee shall continue as
Chairman (but not as the CEO or, unless otherwise determined by the Board of
Directors, as the President) and will continue to play an active role in the
operations and management of the Company, including in the areas of marketing,
engineering, strategic planning and corporate relationships, with leadership
responsibilities and authority in such areas.

        2.      DUTIES. During the period of Employee's employment relationship
with the Company, Employee will devote his best efforts to the interests of the
Company. Employee will not engage in other employment or consultancy without the
prior written consent of the Company, except where he has provided prior written
notice to the Company of his intention to engage in any such activities which in
his reasonable opinion are not adverse to the best interests of the Company and
the Company has not objected to such engagement in writing within ten (10)
business days thereafter. Employee agrees to abide faithfully by all Company
rules, regulations and policies. In the event of any conflict between the
Company's rules, regulations or policies and the terms of this Agreement or
other written agreements between the Company and Employee, the terms of this
Agreement or such other agreement will control.

        3.      COMPENSATION AND BENEFITS.

               3.1 BASE SALARY. The Company agrees to pay Employee a base salary
of $120,000 per year (the "Initial Base Salary"), payable in accordance with the
Company's customary payroll practices, from the Effective Date of this Agreement
until the first closing (the "Initial Base Salary Period") of the Company's
Series A Preferred Stock financing in which the Company sells a minimum of
$2,500,000 of its securities (the "Financing"). Immediately following such
closing, Employee's base salary shall be increased to $145,000 year (the
"Regular Base Salary"), payable in accordance with the Company's customary
payroll practices. Further, promptly following such closing, the Company shall
pay Employee an amount equal to the difference between the Regular Base Salary
and the Initial Base Salary over the Initial Base Salary Period. Employee's base
salary shall be subject to annual review by the Board of Directors, and
increases to such base salary, if any, shall be determined by the Board of
Directors, consistent with the salaries of other senior executives of the
Company. Notwithstanding the foregoing, Employee's base salary shall be at least
equal to the base salary of the Company's Chief Executive Officer, if hired,
unless agreed otherwise by Employee in


<PAGE>   2
writing or by affirmative vote as a member of the Company's Board of Directors.
The provision set forth in the preceding sentence shall terminate and be of no
further force or effect upon the consummation of the sale of the Company's
securities pursuant to a registration statement filed by the Company under the
Securities Act of 1933, as amended, in connection with the firm commitment
underwritten offering of its securities to the general public.

               3.2 CASH BONUSES. Employee shall receive an initial cash bonus
equal to 20% of Employee's Regular Base Salary (or such higher salary as is set
by the Board of Directors), to be paid immediately following the closing of the
Financing. Employee shall further be entitled to participate in the Company's
annual executive bonus plan as may be adopted by the Board of Directors or
modified from time to time; provided, however, that Employee's bonus under such
annual bonus plan shall be at least equal to the bonus received by the Company's
Chief Executive Officer, if hired, under such bonus plan until the consummation
of the sale of the Company's securities pursuant to a registration statement
filed by the Company under the Securities Act of 1933, as amended, in connection
with the firm commitment underwritten offering of its securities to the general
public.

               3.3 START-UP INCENTIVE. Upon execution of this Agreement, the
Company shall pay Employee $12,082 plus an amount equal to all out-of-pocket
start-up costs of the Company incurred by Employee (upon submission to the
Company by Employee of a written expense report).

               3.4 ADDITIONAL BENEFITS. Employee will be eligible to participate
in the Company's employee benefit plans of general application, including
without limitation those plans covering medical, disability and life insurance
(in an amount equal to two years' base salary) in accordance with the rules
established for individual participation in any such plan and applicable law.
Employee will receive two paid vacation days per month and will receive such
other benefits as the Company generally provides to its senior executives and
the Chief Executive Officer (exclusive of relocation related allowances or
assistance).

               3.5 EXPENSES. The Company will reimburse Employee for all
reasonable and necessary expenses incurred by Employee in connection with the
Company's business, provided that such expenses are in accordance with the
Company's applicable policies and are properly documented and accounted for in
accordance with the requirements of the Internal Revenue Service.

        4.      SEVERANCE.

               4.1 DEFINITION OF CAUSE. For purposes of this Section 4, "cause"
shall mean conviction of a felony.

               4.2 DEFINITION OF CHANGE OF CONTROL. For purposes of this Section
4, a "Change of Control" shall mean: (i) a merger transaction or a sale of stock
by existing shareholders of the Company to a single purchaser or group of
affiliated purchasers, as a result of either of which actions shareholders of
the Company's voting capital stock immediately prior to the effective date of
such transaction or sale do not own at least a majority of the outstanding


                                      -2-


<PAGE>   3
shares of the Company's voting capital stock (or other equivalent evidence of
ownership) immediately following such transaction or sale; or (ii) a sale of all
or substantially all of the Company's assets to a third party.

               4.3 TERMINATION OF EMPLOYMENT OTHER THAN FOR CAUSE. In the event
that (i) Employee's employment relationship with the Company is terminated by
the Company other than for cause, (ii) Employee voluntarily terminates his

days of a failure by the Company to comply with any material provision of this
Agreement which has not been cured within thirty (30) days of written notice
thereof by Employee to the Board of Directors, Employee shall be entitled to
severance payments equal to twelve (12) months of Employee's then-current base
salary (payable during such 12 month period on the Company's normal payroll
dates) and shall be entitled to receive continued benefits under the Company's
benefit plans of general application (other than further accrual of vacation
time, which shall cease upon termination of the employment relationship) during
such 12-month period, and Employee agrees in exchange for such severance
payments and benefits continuation to execute a release in reasonable form
provided by the Company releasing each party and its affiliates or related
parties from all claims, known and unknown, which such party may have against
the other party or its affiliates or related parties other than as related to
the payment of such severance, the provision of such benefits or the continued
operation of the applicable provisions of agreements relating to confidential
information which the parties have previously executed.

               4.4 TERMINATION OF EMPLOYMENT FOR CAUSE, DEATH OR DISABILITY. In
the event that Employee's employment relationship with the Company is terminated
for cause or is terminated due to his death or a disability which renders him
unable to perform substantially the functions of his position, Employee shall
not be entitled to the severance payments described in Section 4.3.

               4.5 STOCK VESTING MATTERS. Notwithstanding the vesting schedule
contained in Section 3(a) of the Common Stock Purchase Agreement dated January
13, 1995 between the Company and Gideon and Bina Ben-Efraim, Trustees of the
Gideon Ben-Efraim and Bina Ben-Efraim Family Trust dated July 29, 1994 (the
"Stock Purchase Agreement"), the parties agree that the following provisions
shall apply under the circumstances enumerated below: (i) All of the then
Unvested Shares shall be released from the Company's repurchase option in the
event that the Company is a party to a merger transaction or if a sale of stock
by existing shareholders of the Company to a single purchaser or group of
affiliated purchasers occurs, as a result of either of which actions
shareholders of the Company's voting capital stock immediately prior to the
effective date of such transaction or sale do not own at least a majority of the
outstanding shares of the Company's voting capital stock (or other equivalent
evidence of ownership) immediately


                                      -3-


<PAGE>   4
following such transaction or sale, or if the Company sells all or substantially
all of its assets to a third party; (ii) in addition to the Shares already
released from the Company's original repurchase option, an additional
twenty-five percent ( 25%) of the Shares shall be released from the Company's
repurchase option in the event that the Company hires a Chief Executive Officer
without first obtaining the prior approval of Purchaser and the Purchaser elects
to terminate his employment with the Company within one hundred eighty (180)
days of commencement of employment by such Chief Executive Officer; (iii) in
addition to the Shares already released from the Company's original repurchase
option, an additional twenty-five percent ( 25%) of the Shares shall be released
from the Company's repurchase option, if Purchaser's employment relationship
with the Company is terminated by the Company other than for cause; and (iv) if
Purchaser's employment relationship with the Company is terminated due to his
death or disability (as defined below), then (a) a total of twenty-five percent
(25%) of the Shares shall be released from the Company's repurchase option (in
lieu of what would otherwise have been released under the original repurchase
option) in the event that Purchaser dies or becomes disabled less than one year
after the Vesting Commencement Date, (b) a total of fifty percent (50%) of the
Shares shall be released from the repurchase option (in lieu of what would
otherwise have been released under the original repurchase option) in the event
that Purchaser dies or becomes disabled one year or more but less than two years
after the Vesting Commencement Date, and (c) only that number of Shares provided
by the terms of Section 3(a) of the Stock Purchase Agreement shall be released
from the Company's original repurchase option in the event Purchaser dies or
becomes disabled two years or more after the Vesting Commencement Date. For
purposes of the foregoing paragraph, capitalized terms shall have the meanings
ascribed to them in the Stock Purchase Agreement. For purposes of the foregoing
paragraph, "disability or "disabled" shall refer to a disability which renders
the Employee unable to perform substantially the functions of his position by
reason of any medically determinable substantial physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than 12 months as certified by a
licensed physician

        5.      REGISTRATION RIGHTS. In the event that the Company grants
registration rights to any of its officers or investors with respect to any
shares of the Company's capital stock or other securities issued to them, the
Company shall grant no less favorable registration rights to Employee with
respect to his shares of Common Stock, whether or not Employee is then employed
by the Company.

        6.      CONFIDENTIALITY AGREEMENT. Employee shall sign a Confidentiality
and Inventions Agreement in the form attached hereto as Exhibit A.

        7.      MISCELLANEOUS.

               7.1 SEVERABILITY. If any provision of this Agreement shall be
found by any arbitrator or court of competent jurisdiction to be invalid or
unenforceable, then the parties hereby waive such provision to the extent that
it is found to be invalid or unenforceable and to the extent that to do so would
not deprive one of the parties of the substantial benefit of its bargain. Such
provision shall, to the extent allowable by law and the preceding sentence, be


                                      -4-


<PAGE>   5
modified by such arbitrator or court so that it becomes enforceable consistent
with the intent of this Agreement and, as modified, shall be enforced as any
other provision hereof, all the other provisions continuing in full force and
effect.

               7.2 NO WAIVER. The failure by either party at any time to require
performance or compliance by the other of any of its obligations or agreements
shall in no way affect the right to require such performance or compliance at
any time thereafter. The waiver by either party of a breach of any provision
hereof shall not be taken or held to be a waiver of any preceding or succeeding
breach of such provision or as a waiver of the provision itself. No waiver of
any kind shall be effective or binding, unless it is in writing and is signed by
the party against whom such waiver is sought to be enforced.

               7.3 ASSIGNMENT. This Agreement and all rights hereunder are
personal to Employee and may not be transferred or assigned by Employee at any
time. The Company may assign its rights, together with its obligations
hereunder, to any parent, subsidiary, affiliate or successor, or in connection
with any sale, transfer or other disposition of all or substantially all of its
business and assets, provided, however, that any such assignee assumes the
Company's obligations hereunder, and that such assignment shall be subject to
the severance provisions described in Section 4 to the extent applicable.

               7.4 WITHHOLDING. All sums payable to Employee hereunder shall be
reduced by all federal, state, local and other withholding and similar taxes and
payments required by applicable law.

between the parties relating to the subject matter hereof and thereof, and
supersede any and all previous contracts, arrangements or understandings with
respect hereto and thereto. This Agreement represents the mutual understanding

its drafting or preparation.

hereto.

Ben-Efraim, an individual (the "Employee").

        WHEREAS, the Company and the Employee entered into an Employment
Agreement dated March 27, 1995 (the "Employment Agreement"); and

        WHEREAS, the Company and the Employee desire to amend certain sections
of the Employment Agreement;

        NOW THEREFORE, pursuant to the provisions of Section 7.6 of the

        1.      Section 1 of the Employment Agreement shall be amended to read

serve the Company, as its Chairman of the Board of Directors and Chief Executive
Officer and President until such officer relationships are modified in
accordance with the provisions of the balance of this Section 1 or until
Employee's employment relationship with the Company is terminated by either the
Company or Employee. In the event that another individual is hired to serve as
Chief Executive Officer of the Company (following consultation with Employee) in
the future, Employee shall, so long as he remains an employee of the Company,
continue as Chairman (but not as the CEO or, unless otherwise determined by the
Board of Directors, as the President) and will continue to play an active role
in the operations and management of the Company, including in the areas of
marketing, engineering, strategic planning and corporate relationships, with
leadership responsibilities and authority in such areas."

        2.      Section 3.4 of the Employment Agreement shall be amended to read
in its entirety as follows:

               "3.4 ADDITIONAL BENEFITS. Employee will be eligible to
participate in the Company's employee benefit plans of general application,

insurance (in an amount equal to two years' base salary) in accordance with the
rules established for individual participation in any such plan and applicable
law. Employee will receive paid vacation in accordance with the Company's
vacation policy then in effect (provided that in any case Employee will not
receive fewer paid vacation days than any person appointed in the future as the
Company's Chief Executive Officer or as other senior officers of the Company)
and will receive such other benefits as the Company generally provides to its
senior executives and the Chief Executive Officer (exclusive of relocation
related allowances or assistance)."

        3.      Section 4.3 of the Employment Agreement shall be amended to read
in its entirety as follows:

               "4.3 TERMINATION OF EMPLOYMENT OTHER THAN FOR CAUSE. In the event
that (i) Employee's employment relationship with the Company is terminated by

employment relationship with the Company within thirty (30) days of a change in
Employee's main place of employment to a location outside what is generally

voluntarily terminates his employment relationship with the Company within 60
days of a failure by the Company to comply with any material provision of this
Agreement which has not been cured within thirty (30) days of written notice
thereof by Employee to the Board of Directors, Employee shall be entitled to
severance payments equal to twelve (12) months of Employee's then-current base
salary (payable during such 12 month period on the Company's normal payroll
dates) and shall be entitled to receive continued benefits under the Company's
benefit plans of general application (other than further accrual of vacation
time, which shall cease upon termination of the employment relationship) during
such 12-month period, and Employee agrees in exchange for such severance
payments and benefits continuation to execute a release in reasonable form
provided by the Company releasing each party and its affiliates or related
parties from all claims, known and unknown, which such party may have against
the other party or its affiliates or related parties other than as related to
the payment of such severance, the provision of such benefits or the continued
operation of the applicable provisions of agreements relating to confidential
information which the parties have previously executed."

        4.      All other provisions of the Employment Agreement shall remain in
full force and effect.

        The foregoing Amendment to Employment Agreement is hereby executed as of
the date first above written.

                                                                   Exhibit 10.13

                           CHANGE OF CONTROL AGREEMENT


        This Change of Control Agreement (the "Agreement") is made and entered
into effective as of September 15, 1998, by and between (Employee) (the
"Employee") and Netro Corporation, a California corporation (the "Company").

                                    RECITALS

        A. It is expected that another company or other entity may from time to
time consider the possibility of acquiring the Company or that a change in
control may otherwise occur, with or without the approval of the Company's Board
of Directors (the "Board"). The Board recognizes that such consideration can be
a distraction to the Employee, an executive officer of the Company, and can
cause the Employee to consider alternative employment opportunities. The Board
has determined that it is in the best interests of the Company and its
stockholders to assure that the Company will have the continued dedication and
objectivity of the Employee, notwithstanding the possibility, threat or
occurrence of a Change of Control (as defined below) of the Company.

        B. The Board believes that it is in the best interests of the Company
and its stockholders to provide the Employee with an incentive to continue his
or her employment with the Company, which for purposes of this Agreement as it
relates to Employee's employment shall include a majority-owned subsidiary of
the Company.

        C. The Board believes that it is imperative to provide the Employee with
certain benefits upon termination of the Employee's employment in connection
with a Change of Control, which benefits are intended to provide the Employee
with financial security and provide sufficient encouragement to the Employee to
remain with the Company notwithstanding the possibility of a Change of Control.

        D. To accomplish the foregoing objectives, the Board of Directors has
directed the Company, upon execution of this Agreement by the Employee, to agree
to the terms provided in this Agreement.

        E. Certain capitalized terms used in the Agreement are defined in
Section 3 below.

        In consideration of the mutual covenants contained in this Agreement,
and in consideration of the continuing employment of Employee by the Company,
the parties agree as follows:

        1.      At-Will Employment. The Company and the Employee acknowledge
that the Employee's employment is and shall continue to be at-will, as defined
under applicable law. If the Employee's employment terminates for any reason,
including (without limitation) any termination prior to a Change of Control, the
Employee shall not be entitled to any benefits, other than (A) as provided by
this Agreement, (B) as may be available in accordance with the terms of the
Company's established employee plans and written policies at the time of
termination, (C) as may be provided in Employee's Offer Letter/Employment
Agreement with the Company dated _____________, or (D) as may be approved by the
Board of Directors of the Company in its discretion. The terms of this Agreement
shall terminate upon the earlier of (i) the date on which Employee ceases to be
employed as an executive officer of the Company, other than as a result of


<PAGE>   2
an involuntary termination by the Company without Cause (ii) the date that all
obligations of the parties hereunder have been satisfied, or (iii) one (1) year
after a Change of Control. A termination of the terms of this Agreement pursuant
to the preceding sentence shall be effective for all purposes, except that such
termination shall not affect the provision of benefits on account of a
termination of employment occurring prior to the termination of the terms of
this Agreement.

        2.      Change of Control.

               (a) Termination Following A Change of Control. Subject to
Sections 4 and 5 below, if the Employee's employment with the Company is
terminated at any time within one (1) year after a Change of Control, then the
Employee shall be entitled to receive severance benefits as follows:

                      (i) Voluntary Resignation. If the Employee voluntarily
resigns from the Company (other than as an Involuntary Termination (as defined
below) or if the Company terminates the Employee's employment for Cause (as
defined below)), then the Employee shall not be entitled to receive severance
payments. The Employee's benefits will be terminated under the Company's then
existing benefit plans and policies in accordance with such plans and policies
in effect on the date of termination and in accordance with the terms of the
Employee's Offer Letter/Employment Agreement or as otherwise determined by the
Board of Directors of the Company.

                      (ii) Involuntary Termination. If the Employee's employment
is terminated as a result of an Involuntary Termination other than for Cause,
each stock option to purchase the Company's Common Stock granted to Employee
over the course of his or her employment with the Company (or share of Common
Stock purchased by Employee and subject to a repurchase option in favor of the
Company) and held by Employee on the date of termination of employment shall
become immediately vested (or the repurchase option shall be released) on such
date as to that number of shares that would have vested in accordance with the
terms of such option (or underlying Common Stock Purchase Agreement) (assuming
that Employee had remained in Continuous Status as an Employee, as defined in
the relevant plan and agreement) for two (2) years after the next monthly
vesting date following such termination (e.g., if such option vested as to
additional shares on the 17th day of each month, and such termination were to
occur on the 18th of a month, then the foregoing two (2) year period would begin
after the 17th day of the following month). In the case of options, each such
option shall be exercisable in accordance with the provisions of the option
agreement and plan pursuant to which such option was granted.

                      (iii) Involuntary Termination for Cause. If the Employee's
employment is terminated for Cause, then the Employee shall not be entitled to
receive severance benefits. The Employee's benefits will be terminated under the
Company's then existing benefit plans and policies in accordance with such plans
and policies in effect on the date of termination.

               (b) Termination Apart from A Change of Control. In the event the
Employee's employment terminates for any reason, either prior to the occurrence
of a Change of Control or after one year period following the effective date of
a Change of Control, then the Employee shall not be entitled to receive any
severance benefits under this Agreement. The Employee's benefits will be
terminated under the terms of the Company's then existing benefit plans and
policies in accordance


                                      -2-


<PAGE>   3
with such plans and policies in effect on the date of termination and in
accordance with the terms of the Employee's Offer Letter/Employment Agreement or
as otherwise determined by the Board of Directors of the Company.

        3.      Definition of Terms. The following terms referred to in this
Agreement shall have the following meanings:

               (a) Change of Control. "Change of Control" shall mean the
occurrence of any of the following events:

                      (i) Ownership. Any "Person" (as such term is used in
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is
or becomes the "Beneficial Owner" (as defined in Rule 13d-3 under said Act),
directly or indirectly, of securities of the Company representing more than
thirty percent (30%) or more of the total voting power represented by the
Company's then outstanding voting securities without the approval of the Board
of Directors of the Company;

                      (ii) Merger/Sale of Assets. A merger or consolidation of
the Company whether or not approved by the Board of Directors of the Company,
other than a merger or consolidation which would result in the voting securities
of the Company outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of
the surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Company or such surviving entity
outstanding immediately after such merger or consolidation, or the stockholders
of the Company approve a plan of complete liquidation of the Company or an
agreement for the sale or disposition by the Company of all or substantially all
of the Company's assets; or

                      (iii) Change in Board Composition. A change in the
composition of the Board of Directors of the Company, as a result of which fewer
than a majority of the directors are Incumbent Directors. "Incumbent Directors"
shall mean directors who either (A) are directors of the Company as of December
31, 1997 or (B) are elected, or nominated for election, to the Board of
Directors of the Company with the affirmative votes of at least a majority of
the Incumbent Directors at the time of such election or nomination (but shall
not include an individual whose election or nomination is in connection with an
actual or threatened proxy contest relating to the election of directors to the
Company).

               (b) Cause. "Cause" shall mean (i) gross negligence or willful
misconduct in the performance of the Employee's duties to the Company where such
gross negligence or willful misconduct has resulted or is likely to result in
substantial and material damage to the Company or its subsidiaries, (ii)
repeated unexplained or unjustified absence from the Company, (iii) a material
and willful violation of any federal or state law; (iv) commission of any act of

<PAGE>   4
turpitude causing material harm to the standing and reputation of the Company,
in each case as determined in good faith by the Board of Directors of the
Company.

               (c) Involuntary Termination. "Involuntary Termination" shall
include any termination by the Company other than for Cause and the Employee's
voluntary termination, upon 30 days prior written notice to the Company,
following (i) a material reduction or change in job duties, responsibilities and
requirements from the Employee's duties, responsibilities and requirements prior
to the Change of Control or in the materiality of those responsibilities (for
example, a division president is a material change from the CEO of the Company,
and a division controller is a material change from the CFO of the Company),
(ii) any reduction of the Employee's total compensation and benefits (including
a refusal by the Acquiror to assume any stock option or stock purchase agreement
in its entirety); or (iii) the Employee's refusal to relocate to a location more
than 50 miles from the Company's current location.

        4.      Limitation on Payments.

               (a) In the event that the severance benefits provided for in this
Agreement to the Employee (i) constitute "parachute payments" within the meaning
of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code")
and (ii) but for this Section, would be subject to the excise tax imposed by
Section 4999 of the Code, then the Employee's benefits under Section 2 shall be
payable either: (i) in full, or (ii) as to such lesser amount which would result
in no portion of such severance benefits being subject to excise tax under
Section 4999 of the Code, whichever of the foregoing amounts, taking into
account the applicable federal, state and local income taxes and the excise tax
imposed by Section 4999, results in the receipt by the Employee on an after-tax
basis, of the greatest amount of benefits under Section 2, notwithstanding that
all or some portion of such benefits may be taxable under Section 4999 of the
Code. Unless the Company and the Employee otherwise agree in writing, any
determination required under this Section 4 shall be made in writing by the
Company's independent public accountants (the "Accountants"), whose
determination shall be conclusive and binding upon the Employee and the Company
for all purposes. For purposes of making the calculations required by this
Section 4, the Accountants may make reasonable assumptions and approximations
concerning applicable taxes and may rely on reasonable, good faith
interpretations concerning the application of Section 280G and 4999 of the Code.
The Company and the Employee shall furnish to the Accountants such information
and documents as the Accountants may reasonably request in order to make a
determination under this Section. The Company shall bear all costs the
Accountants may reasonably incur in connection with any calculations
contemplated by this Section 4.

               (b) The payment of severance benefits provided for in this
Agreement shall be subject to all applicable income, employment and social tax
rules and regulations.

        5.      Successors. Any successor to the Company (whether direct or
indirect and whether by purchase, lease, merger, consolidation, liquidation or
otherwise) to all or substantially all of the Company's business and/or assets
shall assume the obligations under this Agreement and agree expressly to perform
the obligations under this Agreement in the same manner and to the same extent
as the Company would be required to perform such obligations in the absence of a
succession. The terms of this Agreement and all of the Employee's rights
hereunder shall inure


                                       -4-

to the benefit of, and be enforceable by, the Employee's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees.

        6.      Notice. Notices and all other communications contemplated by
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid. Mailed notices to the Employee
shall be addressed to the Employee at the home address which the Employee most
recently communicated to the Company in writing. In the case of the Company,
mailed notices shall be addressed to its corporate headquarters, and all notices
shall be directed to the attention of its Secretary.

        7.      Miscellaneous Provisions.

               (a) No Duty to Mitigate. The Employee shall not be required to
mitigate the amount of any payment contemplated by this Agreement (whether by
seeking new employment or in any other manner), nor, except as otherwise
provided in this Agreement, shall any such payment be reduced by any earnings
that the Employee may receive from any other source.

               (b) Waiver. No provision of this Agreement shall be modified,
waived or discharged unless the modification, waiver or discharge is agreed to
in writing and signed by the Employee and by an authorized officer of the
Company (other than the Employee). No waiver by either party of any breach of,
or of compliance with, any condition or provision of this Agreement by the other
party shall be considered a waiver of any other condition or provision or of the
same condition or provision at another time.

               (c) Whole Agreement. No agreements, representations or
understandings (whether oral or written and whether express or implied) which
are not expressly set forth in this Agreement have been made or entered into by
either party with respect to the subject matter hereof. This Agreement
supersedes any agreement of the same title and concerning similar subject matter
dated prior to the date of this Agreement, and by execution of this Agreement
both parties agree that any such predecessor agreement shall be deemed null and
void.

               (d) Choice of Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the laws of the State of
California without reference to conflict of laws provisions.

               (e) Severability. If any term or provision of this Agreement or
the application thereof to any circumstance shall, in any jurisdiction and to
any extent, be invalid or unenforceable, such term or provision shall be
ineffective as to such jurisdiction to the extent of such invalidity or
unenforceability without invalidating or rendering unenforceable the remaining
terms and provisions of this Agreement or the application of such terms and
provisions to circumstances other than those as to which it is held invalid or
unenforceable, and a suitable and equitable term or provision shall be
substituted therefor to carry out, insofar as may be valid and enforceable, the
intent and purpose of the invalid or unenforceable term or provision.

               (f) Arbitration. Any dispute or controversy arising under or in
connection with this Agreement may be settled at the option of either party by
binding arbitration in the County of


                                      -5-

Santa Clara, California, in accordance with the rules of the American
Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction. Punitive damages shall not
be awarded.

               (g) Legal Fees and Expenses. The parties shall each bear their
own expenses, legal fees and other fees incurred in connection with this
Agreement.

               (h) No Assignment of Benefits. The rights of any person to
payments or benefits under this Agreement shall not be made subject to option or
assignment, either by voluntary or involuntary assignment or by operation of
law, including (without limitation) bankruptcy, garnishment, attachment or other
creditor's process, and any action in violation of this subsection (h) shall be
void.

               (i) Employment Taxes. All payments made pursuant to this
Agreement will be subject to withholding of applicable income and employment
taxes.

               (j) Assignment by Company. The Company may assign its rights
under this Agreement to an affiliate, and an affiliate may assign its rights
under this Agreement to another affiliate of the Company or to the Company;
provided, however, that no assignment shall be made if the net worth of the
assignee is less than the net worth of the Company at the time of assignment. In
the case of any such assignment, the term "Company" when used in a section of
this Agreement shall mean the corporation that actually employs the Employee.

               (k) Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together will
constitute one and the same instrument.

Shares, the Conversion Shares or the Common Shares to agree to take and hold
such securities subject to the provisions and upon the conditions specified in
this Agreement.

        1.3 Restrictive Legend. Each certificate representing (i) the Preferred

securities laws):

        "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
        INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

        AND PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT."

        "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
        ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE

<PAGE>   5

        1.4 Notice of Proposed Transfers. The holder of each certificate
representing Restricted Securities, by acceptance thereof, agrees to comply in
all respects with the provisions of this Section 1. Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities, unless there is in
effect a registration statement under the Securities Act covering the proposed
transfer, the holder thereof shall give written notice to the Company of such
holder's intention to effect such transfer, sale, assignment or pledge. Each
such notice shall describe the manner and circumstances of the proposed
transfer, sale, assignment or pledge in sufficient detail, and shall be
accompanied at such holder's expense by either (i) an unqualified written
opinion of legal counsel who shall, and whose legal opinion shall be, reasonably
satisfactory to the Company, addressed to the Company, to the effect that the
proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act, or (ii) a "no action" letter from the
Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. The Company will not require such a legal opinion or "no action" letter
(a) in any transaction in compliance with Rule 144, (b) in any transaction in
which an Investor which is a corporation distributes Restricted Securities after
six (6) months after the purchase thereof solely to its majority-owned
subsidiaries or affiliates for no consideration, or (c) in any transaction in
which an Investor which is a partnership distributes Restricted Securities after
six (6) months after the purchase thereof solely to partners thereof for no
consideration, provided that each transferee agrees in writing to be subject to
the terms of this Section 1.4. Each certificate evidencing the Restricted
Securities transferred as above provided shall bear, except if such transfer is
made pursuant to Rule 144, the appropriate restrictive legend set forth in
Section 1.3 above, except that such certificate shall not bear such restrictive
legend if, in the opinion of counsel for such holder and the Company, such
legend is not required in order to establish compliance with any provisions of
the Securities Act.

        1.5 Request for Registration.

                (a) In case the Company shall receive from the Initiating
Holders a written request that the Company effect any registration,
qualification or compliance with respect to the Registrable Securities, the
Company will:

                        (i) promptly give written notice of the proposed
registration, qualification or compliance to all other Holders; and

                        (ii) as soon as practicable, use its best efforts to
effect such registration, qualification or compliance (including, without
limitation, the execution of an undertaking to file post-effective amendments,
appropriate qualification under applicable blue sky or other state securities
laws and appropriate compliance with applicable regulations issued under the
Securities Act and any other governmental requirements or regulations) as may be
so requested and as would permit or facilitate the sale and distribution of all
or such portion of such Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders joining in such request as are specified in a written request received
by the Company within twenty (20) days after receipt of such written notice from
the Company; provided, however, that the Company shall not be obligated to take
any action to effect


<PAGE>   6

any such registration, qualification or compliance pursuant to this Section 1.5:

                                (1) In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                                (2) Prior to the earlier of (i) two (2) years
from the date of this Agreement or (ii) six months following the Company's
initial public offering;

                                (3) During the period ending on the date three
(3) months immediately following the effective date of, any registration
statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit
plan);

                                (4) After the Company has effected two (2) such
registration pursuant to this subparagraph 1.5(a), such registration has been
declared or ordered effective and the securities offered pursuant to such
registration have been sold; or

                                (5) If the Company shall furnish to such Holders
a certificate, signed by the President of the Company, stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 1.5 shall be deferred for a single period
not to exceed one hundred-twenty (120) days from the date of receipt of written
request from the Initiating Holders.

        Subject to the foregoing clauses (1) through (5), the Company shall file
a registration statement covering the Registrable Securities so requested to be
registered as soon as practicable after receipt of the request or requests of
the Initiating Holders.

                (b) Underwriting. In the event that a registration pursuant to
Section 1.5 is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1.5(a)(i). The right of any Holder to registration pursuant to Section
1.5 shall be conditioned upon such Holder's participation in the underwriting
arrangements required by this Section 1.5 and the inclusion of such Holder's
Registrable Securities in the underwriting, to the extent requested, to the
extent provided in this Agreement.

        The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with the managing underwriter selected for such underwriting
by a majority in interest of the Initiating Holders (which managing underwriter
shall be reasonably acceptable to the Company). Notwithstanding any other
provision of this Section 1.5, if the managing underwriter advises the
Initiating Holders in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the Company shall so advise all
Holders of Registrable Securities and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated among all Holders thereof in proportion, as nearly as practicable, to
the respective amounts of Registrable Securities held by such Holders at the
time of filing the


<PAGE>   7

registration statement. No Registrable Securities excluded from the underwriting
by reason of the underwriter's marketing limitation shall be included in such
registration. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

        If any Holder of Registrable Securities disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the managing underwriter and the Initiating Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of such registration.

        1.6 Company Registration.

                (a) Notice of Registration. If at any time or from time to time,
the Company shall determine to register any of its securities, either for its
own account or the account of a security holder or holders other than (i) a
registration relating solely to employee benefit plans, or (ii) a registration
relating solely to a Commission Rule 145 transaction, the Company will:

                        (i) promptly give to each Holder written notice thereof;
and

                        (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved in such registration, all the Registrable Securities specified in a
written request or requests made within twenty (20) days after receipt of such
written notice from the Company by any Holder, but only to the extent that such
inclusion will not diminish the number of securities included by the Company or
by holders of the Company's securities who have demanded such registration.

                (b) Underwriting. If the registration of which the Company gives
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.6(a)(i). In such event, the right of any Holder to
registration pursuant to Section 1.6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company (or by the
holders who have demanded such registration). Notwithstanding any other
provision of this Section 1.6, if the managing underwriter determines that
marketing factors require a limitation of the number of shares to be
underwritten, the managing underwriter may limit the Registrable Securities to
be included in such registration to a minimum of 25% of the total shares to be
included in such underwriting or exclude them entirely in the case of the
Company's initial public offering. The Company shall so advise all Holders and
the other holders distributing their securities through such underwriting
pursuant to piggyback registration rights similar to this Section 1.6, and the
number of shares of Registrable Securities and other securities that may be
included in the registration and underwriting shall be allocated among all
Holders and other holders in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by


<PAGE>   8

such Holders and other securities held by other holders at the time of filing
the registration statement. To facilitate the allocation of shares in accordance
with the above provisions, the Company or the underwriters may round the number
of shares allocated to any Holder or other holder to the nearest 100 shares. If
any Holder or other holder disapproves of the terms of any such underwriting, he
or she may elect to withdraw therefrom by written notice to the Company and the
managing underwriter. Any securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration, and shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of the registration statement relating thereto.

                (c) Right to Terminate Registration. The Company shall have the
right to terminate or withdraw any registration initiated by it under this
Section 1.6 prior to the effectiveness of such registration, whether or not any
Holder has elected to include securities in such registration.

        1.7 Registration on Form S-3.

                (a) If any Holder requests that the Company file a registration
statement on Form S-3 (or any successor form to Form S-3) for a public offering
of shares of the Registrable Securities, the reasonably anticipated aggregate
price to the public of which, net of underwriting discounts and commissions,
would exceed $500,000, and the Company is a registrant entitled to use Form S-3
to register the Registrable Securities for such an offering, the Company shall
use its best efforts to cause such Registrable Securities to be registered for
the offering on such form; provided, however, that the Company shall not be
required to effect more than one registration pursuant to this Section 1.7 in
any twelve (12) month period. The Company will (i) promptly give written notice
of the proposed registration to all other Holders, and (ii) as soon as
practicable, use its best efforts to effect such registration (including,
without limitation, the execution of an undertaking to file post-effective
amendments, appropriate qualification under applicable blue sky or other state
securities laws and appropriate compliance with applicable regulations issued
under the Securities Act and any other governmental requirements or regulations)
as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holder or Holders joining in such request as are specified in
a written request received by the Company within twenty (20) days after receipt
of such written notice from the Company. The substantive provisions of Section
1.5(b) shall be applicable to each registration initiated under this Section
1.7.

                (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 1.7: (i) in any particular
jurisdiction in which the Company would be required to execute a general consent
to service of process in effecting such registration, qualification or
compliance unless the Company is already subject to service in such jurisdiction
and except as may be required by the Securities Act, (ii) during the period
ending on a date three (3) months following the effective date of, a
registration statement (other than with respect to a registration statement
relating to a Rule 145 transaction, an offering solely to employees or any other
registration which is not appropriate for the registration of Registrable
Securities), or (iii) if the Company shall furnish to such Holder a certificate
signed by the President of the Company stating that, in the good faith judgment
of the Board of Directors, it would be seriously


<PAGE>   9

detrimental to the Company or its shareholders for registration statements to be
filed in the near future, then the Company's obligation to use its best efforts
to file a registration statement shall be deferred for a single period not to
exceed one hundred twenty (120) days from the receipt of the request to file
such registration by such Holder or Holders.

        1.8 Limitations on Subsequent Registration Rights. From and after the
date of this Agreement, the Company shall not enter into any agreement granting
any holder or prospective holder of any securities of the Company registration
rights with respect to such securities unless such shares or securities are
entitled to be included in registrations only to the extent that the inclusion
of such securities will not diminish the amount of Registrable Securities that
are included.

        1.9 Expenses of Registration. All Registration Expenses incurred in
connection with any registration pursuant to Sections 1.5 and 1.6 and the
reasonable cost of one special legal counsel to represent all of the Holders
together in any such registration shall be borne by the Company, provided that
the Company shall not be required to pay the Registration Expenses of any
registration proceeding begun pursuant to Section 1.5, the request of which has
been subsequently withdrawn by the Initiating Holders. In such case, the holders
of Registrable Securities to have been registered shall bear all such
Registration Expenses pro rata on the basis of the number of shares to have been
registered unless the Holders holding a majority of the Registrable Securities,
as appropriate, agree to forfeit their right to one demand registration pursuant
to Section 1.5. Notwithstanding the foregoing, however, if at the time of the
withdrawal, the Holders have learned of a material adverse change in the
condition, business or prospects of the Company from that known to such Holders
at the time of their request, of which the Company had knowledge at the time of
the request, then the Holders shall not be required to pay any of said
Registration Expenses or to forfeit the right to one demand registration. Unless
otherwise stated, all other Selling Expenses relating to securities registered
on behalf of the Holders and all Registration Expenses incurred in connection
with any registration pursuant to Section 1.7 shall be borne by the Holders of
the registered securities included in such registration pro rata on the basis of
the number of shares so registered.

        1.10 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

                (a) Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least one hundred
eighty (180) days or until the distribution described in the registration
statement has been completed; and

                (b) Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement, preliminary prospectus, final
prospectus and such other documents as such underwriters may reasonably request
in order to facilitate the public offering of such securities.

        1.11 Indemnification.


<PAGE>   10

                (a) The Company will indemnify each Holder, each of its
trustees, officers and directors and partners, and each person controlling such
Holder within the meaning of Section 15 of the Securities Act, with respect to
which registration, qualification or compliance has been effected pursuant to
this Section 1, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the Securities Act, against all
expenses, claims, losses, damages or liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, or any violation by the Company of any rule or regulation
promulgated under the Securities Act applicable to the Company in connection
with any such registration, qualification or compliance, and the Company will
reimburse each such Holder, each of its officers and directors, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder, controlling person or underwriter and stated to be specifically for use
therein.

                (b) Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter, if any, of the Company's
securities covered by such a registration statement, each person who controls
the Company or such underwriter within the meaning of Section 15 of the
Securities Act, and each other such Holder, each of its officers and directors
and each person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all claims, losses, damages and liabilities (or actions
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the Company, such Holders, such directors, officers, persons, underwriters or
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder and
stated to be specifically for use therein; provided, however, that the liability
of a Holder for indemnification under this Section 1.11(b) shall not exceed the
gross proceeds from the offering received by such Holder.

                (c) Each party entitled to indemnification under this Section
1.11 (the


<PAGE>   11

"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Section 1 unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action.
No Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

        1.12 Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as the Company may
request in writing and as shall be required in connection with any registration,
qualification or compliance referred to in this Section 1.

        1.13 Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to use its best efforts to:

                (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act, at all times
after the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended (the "Exchange Act");

                (b) File with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements); and

                (c) So long as an Investor owns any Restricted Securities, to
furnish to the Investor forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents of the Company and other information in the possession of or
reasonably obtainable by the Company as an Investor may reasonably request in
availing itself of any rule or regulation of the Commission allowing an Investor
to sell any such securities without registration.

        1.14 Transfer of Registration Rights. The rights to cause the Company to
register


<PAGE>   12

securities granted Investors under Sections 1.5, 1.6 and 1.7 may be assigned to
a transferee or assignee reasonably acceptable to the Company in connection with
any transfer or assignment of Registrable Securities by an Investor (together
with any affiliate); provided, that (a) such transfer may otherwise be effected
in accordance with applicable securities laws, (b) notice of such assignment is
given to the Company, and (c) such transferee or assignee (i) is a wholly-owned
subsidiary or constituent partner (including limited partners) of such Investor,
or (ii) acquires from such Investor the lesser of (a) 100,000 or more shares of
Restricted Securities (as appropriately adjusted for stock splits and the like)
or (b) all of the Restricted Securities then owned by such Investor.

        1.15 Standoff Agreement. Each Investor, and any transferee of shares
held by an Investor, agrees in connection with the initial registration of the
Company's securities that, upon request of the Company or the underwriters
managing any underwritten initial public offering of the Company's securities,
not to sell, make any short sale of, loan, grant any option for the purchase of,
or otherwise dispose of any Registrable Securities (other than those included in
the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days from the effective date of such registration) as may
be requested by the Company or such managing underwriters; provided that the
officers and directors of the Company who own stock of the Company also agree to
such restrictions.

        1.16 Termination of Rights. The rights of any particular Holder to cause
the Company to register securities under Sections 1.5, 1.6 and 1.7 shall
terminate with respect to such Holder following a bona fide firm underwritten
public offering of shares of the Company's Common Stock registered under the
Securities Act (provided the aggregate offering price, net of underwriting
discounts and commissions, exceeds ten million dollars ($10,000,000)) at such
time as such Holder is able to dispose of all its Registrable Securities in one
three-month period pursuant to the provisions of Rule 144; provided, that such
Holder holds Registrable Securities constituting less than 1% of the outstanding
voting stock of the Company.

                                    SECTION 2

                             Right of Participation

        2.1 Purchasers' Right of Participation.

                (a) Right of Participation. Subject to the terms and conditions
contained in this Section 2.1, the Company hereby grants to each Purchaser the
right of participation to purchase its Pro Rata Portion of any New Securities
(as defined in subsection 2.1(b)) which the Company may, from time to time,
propose to sell and issue. A Purchaser's "Pro Rata Portion" for purposes of this
Section 2.1 is the ratio that (x) the sum of the number of shares of the
Company's Common Stock then held by such Purchaser and the total number of
shares of the Company's Common Stock issuable upon conversion of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock then held by such Purchaser bears to (y) the sum of the total
number of shares of the Company's Common Stock then outstanding and the total
number of shares of the Company's Common Stock issuable upon conversion of the
then outstanding Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock


<PAGE>   13

and Series D Preferred Stock.

                (b) Definition of New Securities. Except as set forth below,
"New Securities" shall mean any shares of capital stock of the Company,
including Common Stock and Preferred Stock, whether authorized or not, and
rights, options or warrants to purchase said shares of Common Stock or Preferred
Stock, and securities of any type whatsoever that are, or may become,
convertible into said shares of Common Stock or Preferred Stock. Notwithstanding
the foregoing, "New Securities" does not include (i) the Common Shares, the
Preferred Shares or the Conversion Shares, (ii) securities offered to the public
generally pursuant to a registration statement under the Securities Act, (iii)
securities issued pursuant to the acquisition of another corporation by the
Company by merger, purchase of substantially all of the assets or shares or
other reorganization whereby the Company or its shareholders own not less than a
majority of the voting power of the surviving or successor corporation, (iv)
shares of the Company's Common Stock or related options or warrants convertible
into or exercisable for such Common Stock issued to employees, officers and
directors of, and consultants to, the Company, pursuant to any arrangement
approved by the Board of Directors of the Company, (v) shares of the Company's
Common Stock or related options or warrants convertible into or exercisable for
such Common Stock issued to customers and vendors of the Company pursuant to any
arrangement unanimously approved by the Board of Directors of the Company; (vi)
shares of the Company's Common Stock or related options convertible into or
exercisable for such Common Stock issued to banks, commercial lenders, lessors
and other financial institutions in connection with the borrowing of money or
the leasing of equipment by the Company, (vii) stock issued pursuant to any
rights or agreements, including, without limitation, convertible securities,
options and warrants, provided that the Company shall have complied with the
rights of participation established by this Section 2.1 with respect to the
initial sale or grant by the Company of such rights or agreements, or (viii)
stock issued in connection with any stock split, stock dividend or
recapitalization by the Company.

                (c) Notice of Right. In the event the Company proposes to
undertake an issuance of New Securities, it shall give each Purchaser written
notice of its intention, describing the type of New Securities and the price and
terms upon which the Company proposes to issue the same. Each Purchaser shall
have twenty (20) days from the date of receipt of any such notice to agree to
purchase shares of such New Securities (up to the amount referred to in
subsection 2.1(a)), for the price and upon the terms specified in the notice, by
giving written notice to the Company and stating therein the quantity of New
Securities to be purchased.

                (d) Exercise of Right. If any Purchaser exercises its right of
participation under this Agreement, the closing of the purchase of the New
Securities with respect to which such right has been exercised shall take place
within ninety (90) calendar days after the Purchaser gives notice of such
exercise, which period of time shall be extended in order to comply with
applicable laws and regulations. Upon exercise of such right of participation,
the Company and the Purchaser shall be legally obligated to consummate the
purchase contemplated thereby and shall use their best efforts to secure any
approvals required in connection therewith.

                (e) Lapse and Reinstatement of Right. In the event a Purchaser
fails to exercise the right of participation provided in this Section 2.1 within
said twenty (20) day period, the Company shall have ninety (90) days thereafter
to sell or enter into an agreement (pursuant to


<PAGE>   14

which the sale of New Securities covered thereby shall be closed, if at all,
within sixty (60) days from the date of said agreement) to sell the New
Securities not elected to be purchased by such Purchaser at the price and upon
the terms no more favorable to the purchasers of such securities than specified
in the Company's notice. In the event the Company has not sold the New
Securities or entered into an agreement to sell the New Securities within said
ninety (90) day period (or sold and issued New Securities in accordance with the
foregoing within sixty (60) days from the date of said agreement), the Company
shall not thereafter issue or sell any New Securities without first offering
such securities to the Purchasers in the manner provided above.

                (f) Assignment. The right of the Purchasers to purchase any part
of the New Securities may be assigned in whole or in part to any partner,
subsidiary, affiliate or shareholder of a Purchaser, or other persons or
organizations who acquire the lesser of (i) 100,000 or more shares of Restricted
Securities (as adjusted for stock splits and the like) or (ii) all of the
Restricted Securities then owned by such Purchaser.

        2.2 Termination of Participation Right. The rights of participation
granted under Section 2.1 of this Agreement shall terminate on and be of no
further force or effect upon the earlier of (i) the consummation of the
Company's sale of its Common Stock in an underwritten public offering pursuant
to an effective registration statement filed under the Securities Act
immediately subsequent to which the Company shall be obligated to file annual
and quarterly reports with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act or (ii) the registration by the Company of a class of its equity
securities under Section 12(b) or 12(g) of the Exchange Act.

        2.3 Waiver of Prior Right. Pursuant to the terms of the June 1995 Rights
Agreement, the November 1995 Rights Agreement, the July 1996 Rights Agreement,
the 1997 Rights Agreement, the November 1997 Rights Agreement, the December 1997
Rights Agreement and the July 1998 Rights Agreement, the Purchasers hereby waive
any right of pro rata participation which may have accrued to them in the past
with respect to any prior issuance of securities by the Company, including the
issuance of shares of Series D Preferred Stock to certain Series D Purchasers in
connection herewith.

                                    SECTION 3

                                  Miscellaneous

        3.1 Assignment. Except as otherwise provided in this Agreement, the
terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the respective successors and assigns of the parties to this
Agreement.

        3.2 Third Parties. Nothing in this Agreement, express or implied, is
intended to confer upon any party, other than the parties to this Agreement, and
their respective successors and assigns, any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.

        3.3 Governing Law. This Agreement shall be governed by and construed
under the laws of the State of California in the United States of America
without giving effect to the conflicts of laws principles thereof.


<PAGE>   15

        3.4 Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

        3.5 Notices. Any notice, demand or request required or permitted to be
given under this Agreement shall be in writing and shall be deemed sufficient
when delivered personally by a recognized international courier (e.g., Federal
Express or DHL) or sent by confirmed facsimile, and addressed, if to the
Company, at its principal place of business, attention the President, and if to
a Purchaser, at their address as shown on the stock records of the Company. Such
notice shall be effective upon receipt by the organization being notified.

        3.6 Severability. If one or more provisions of this Agreement are held
to be unenforceable under applicable law, portions of such provisions, or such
provisions in their entirety, to the extent necessary, shall be severed from
this Agreement, and the balance of this Agreement shall be enforceable in
accordance with its terms.

        3.7 Amendment and Waiver. Any provision of this Agreement may be amended
or waived with the written consent of the Company and the Holders of at least a
majority of the outstanding shares of the Registrable Securities, so long as the
effect is to treat all Holders equally. Any amendment or waiver effected in
accordance with this paragraph shall be binding upon each Holder of Registrable
Securities and the Company. In addition, the Company may waive performance of
any obligation owing to it, as to some or all of the Holders of Registrable
Securities, or agree to accept alternatives to such performance, without
obtaining the consent of any Holder of Registrable Securities. In the event that
an underwriting agreement is entered into between the Company and any Holder,
and such underwriting agreement contains terms differing from this Agreement, as
to any such Holder the terms of such underwriting agreement shall govern.

        3.9 Rights of Holders. Each holder of Registrable Securities shall have
the absolute right to exercise or refrain from exercising any right or rights
that such holder may have by reason of this Agreement, including, without
limitation, the right to consent to the waiver or modification of any obligation
under this Agreement, and such holder shall not incur any liability to any other
holder of any securities of the Company as a result of exercising or refraining
from exercising any such right or rights.

        3.10 Delays or Omissions. No delay or omission to exercise any right,
power or remedy accruing to any party to this Agreement, upon any breach or
default of the other party, shall impair any such right, power or remedy of such
non-breaching party nor shall it be construed to be a waiver of any such breach
or default, or an acquiescence therein, or of or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring. Any waiver,


<PAGE>   16

permit, consent or approval of any kind or character on the part of any party of
any breach or default under this Agreement, or any waiver on the part of any
