                                  THE COMPANY
 
  Metawave Communications Corporation ("Metawave" or the "Company") designs,
develops, manufactures and markets spectrum management solutions for the
wireless communications industry. Metawave's spectrum management solutions,
consisting of smart antenna systems, applications software and engineering
services, enable cellular network operators to increase overall network
capacity, reduce network operation costs, better manage network infrastructure
and stimulate end user demand through improved system quality.
 
  The Company's smart antenna systems utilize fixed beam-switching hardware and
software algorithms to reduce system interference in order to enable more
efficient utilization of finite radio frequency spectrum or "wireless
bandwidth." The Company's products offer highly integrated system solutions
that can reduce the need for costly infrastructure upgrades and additional cell
site deployments, thereby enabling cellular network operators to reduce
otherwise capital intensive outlays and to keep pace with subscriber growth.
The Company's technology is designed to be leveraged across a variety of the
market segments in the wireless communications industry, including the AMPS,
CDMA, GSM, PCS, TDMA and wireless local loop ("WLL") segments. The Company's
customers include ALLTEL Communications Inc. ("ALLTEL"), 360(degrees)
Communications Company ("360(degrees) Communications") and Millicom
International Cellular S.A. ("Millicom") affiliates, Telefonica Celular del
Paraguay S.A. ("Telefonica Celular") and OJSC St. Petersburg Telecom ("St.
Petersburg Telecom"). The Company has completed a field trial with AirTouch
Communications, Inc. ("AirTouch") and is currently conducting a field trial
with GTE Corporation ("GTE").
 
  The worldwide demand for wireless communications services has grown
significantly, largely as a result of technological advancements, deregulation
and economies of scale that have substantially reduced the cost and improved
the quality and reliability of wireless services for the business and consumer
mass market. Increased demand for wireless services places a significant strain
on wireless network operators which have a fixed amount of radio frequency
spectrum or wireless bandwidth available to deliver wireless services. Unlike
traditional data and telephony communications bandwidth, which is an expandable
physical medium, wireless spectrum is generally allocated in fixed amounts by
governments in U.S. and foreign markets. Thus, the fundamental challenge for
wireless network operators is to increase capacity, coverage and call quality
within a fixed amount of wireless spectrum.
 
                                       3
<PAGE>
 
 
  To address capacity, coverage and call quality issues, cellular network
operators have begun to deploy more spectrum-efficient digital technologies.
However, because analog and digital technologies share the same fixed amount of
spectrum in a cellular network, cellular network operators must remove analog
channels to implement digital technologies, while simultaneously providing
analog cellular service to increasing numbers of subscribers. Traditionally,
cellular network operators have addressed capacity, coverage and call quality
problems by building new cell sites or adopting variations on antenna design
such as sectorized antennas.
 
  Metawave's spectrum management platform, the Spotlight 2000 system, is a
multibeam smart antenna technology that enables the transition from traditional
wireless network infrastructure design to an architecture which actively
optimizes finite spectrum or wireless bandwidth. The SpotLight 2000 system is
compatible with the Motorola, Inc. ("Motorola") HDII and Lucent Technologies
Inc. ("Lucent") Series II base stations and AMPS and CDMA air interface
protocols. Metawave's spectrum management solutions provide cost-effective
capacity expansion, efficient conversion to digital network capability and
improved network performance. Metawave's SpotLight 2000 system is currently
deployed in cellular networks in North America, South America and Europe.
 
  Metawave's objective is to be a leading provider of spectrum management
solutions to the worldwide wireless communications market. Key elements of the
Company's strategy include: (i) identifying rapidly growing wireless markets
and developing highly integrated solutions to their spectrum management
problems; (ii) building and expanding strategic customer relationships; (iii)
leveraging its proprietary core technology, which includes eight issued U.S.
patents and 25 pending patent applications, by investing substantial resources
in the research and product development necessary to address additional
markets; and (iv) offering system level solutions, including pre-sales system
planning, configurable products and on-site installation and optimization, that
enhance the performance of cellular operators' networks.
 
  Metawave sells its products through a technical direct sales force supported
by systems engineers. Direct sales personnel are assigned on a customer account
basis and are responsible for generating product sales and providing product
and customer support. As of June 30, 1998, the Company had 200 employees,
including 43 in sales, marketing and customer support, located in the Company's
Redmond, Washington, Washington, D.C. and Dallas, Texas offices.
 
  The Company's principal executive offices are located at 10735 Willows Road
NE, Redmond, Washington 98073-9769, and its telephone number is (425) 702-5600.
The Company was originally incorporated in the state of Washington in January
1995 and was reincorporated in the state of Delaware in July 1995.

                                 RISK FACTORS
 
  An investment in the shares offered hereby involves a high degree of risk.
The following risk factors should be considered carefully in addition to the
other information in this Prospectus before purchasing the shares of Common
Stock offered hereby. The discussion in this Prospectus contains certain
forward-looking statements that involve risks and uncertainties, such as
statements of the Company's plans, objectives, expectations and intentions.
The cautionary statements made in this Prospectus should be read as being
applicable to all related forward-looking statements wherever they appear in
this Prospectus. The Company's actual results could differ materially from
those discussed herein. Factors that could cause or contribute to such
differences include those discussed below as well as those discussed elsewhere
herein.
 
  Limited Operating History; Accumulated Deficit; Anticipated Losses. The
Company was incorporated in 1995 and was in the development stage until late
1997, when it commenced shipments for commercial sale of its first spectrum
management system. From inception through June 30, 1998, the Company generated
total revenues of approximately $9.2 million, of which $6.5 million, or 70.6%,
was generated in the six months ended June 30, 1998. For the quarters ended
March 31, 1998 and June 30, 1998, the Company's net losses were $7.0 million
and $9.2 million, respectively and, at June 30, 1998, the Company had a
cumulative net loss of approximately $50.1 million. The revenue and profit
potential of the Company's business is unproven and the Company's limited
operating history makes its future operating results difficult to predict. The
Company believes that its growth and future success will be dependent upon the
widespread acceptance of the SpotLight 2000 system by cellular network
operators. Because the SpotLight 2000 system was only recently introduced, the
Company is unable to predict with any degree of certainty whether the system
will achieve market acceptance. There can be no assurance that the Company
will ever achieve profitability or significant revenues on a quarterly or an
annual basis. The Company intends to continue to make significant investments
in its operations, particularly to support product development, to increase
manufacturing capacity and to market new products. Accordingly, the Company
expects to continue to generate losses for the foreseeable future, even if
revenues increase. In view of the Company's limited production history, an
investment in the Common Stock offered hereby must be considered in light of
the problems, expenses, complications and delays frequently encountered in
connection with the development of new technologies, products, markets and
operations. As a result of the Company's net losses and limited operating
history, period-to-period comparisons of operating results may not be
meaningful and operating results from prior periods may not be indicative of
future performance. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  Significant Fluctuations in Operating Results. The Company will likely
experience significant fluctuations in its operating results on a quarterly
and an annual basis in the future. In connection with its efforts to increase
production of its recently introduced SpotLight 2000 system, the Company
expects to continue to make substantial investments in capital equipment, to
recruit and train additional personnel and to invest in facilities and
management information systems. These expenditures may be made in advance of,
and in anticipation of, increased sales and, therefore, gross profits may be
adversely affected by short-term inefficiencies associated with the addition
of equipment, personnel or facilities, and costs may increase as a percentage
of revenues from time-to-time on a periodic basis. As a result, the Company's
operating results will vary from period to period. Because of the limited size
of the Company's customer base and the large size of customer orders, revenues
derived from a small number of customers will likely represent a significant
portion of revenue in any given period. Accordingly, a decrease in demand for
the Company's systems from any customer for any reason is likely to result in
significant periodic fluctuations in revenue. In addition, most of the
Company's contracts contain conditional acceptance provisions for certain
product sales and the Company delays recognition of revenues that are subject
to such contingencies until all such conditions are satisfied. If the Company
could not satisfy conditions in such
 
                                       6
<PAGE>
 
contracts or satisfaction of conditions were delayed for any reason, revenues
in any particular period could fall significantly below the Company's
expectations.
 
  A delay in a shipment or customer acceptance of the Company's product near
the end of a particular quarter, due to, for example, an unanticipated
shipment rescheduling, cancellation or deferral by a customer, competitive or
economic factors, unexpected manufacturing, installation or other
difficulties, failure to satisfy customer acceptance conditions,
unavailability or delays in deliveries of components, subassemblies or
services by suppliers, or the failure to receive an anticipated order, may
cause revenue in a particular period to fall significantly below the Company's
expectations and may materially adversely affect the Company's business and
operating results for such period. A significant portion of the Company's
expenses are fixed in advance and based in large part on revenue forecasts. If
revenues do not meet the Company's expectations in any given period, the
adverse impact on operating results of such a shortfall may be magnified by
the Company's inability to adjust spending to compensate for the shortfall. In
addition, the Company plans to increase operating expenses to fund additional
research and development, sales and marketing and general and administrative
activities. To the extent that these expenses are not accompanied by an
increase in revenues, the Company's business and operating results would be
materially adversely affected.
 
  Other factors that may cause the Company's revenue, gross profits and
results of operations to vary significantly from period to period include:
gain or loss by the Company of significant customers; delays in, or
prohibition of, installing the Company's systems due to topological or zoning
issues or customer installation schedules; the Company's ability to reduce
costs; existing and new product development; market acceptance and the timing
of availability of new products by the Company or its customers; changes in
pricing by the Company, its customers or suppliers; introduction and
enhancement of products by the Company and its competitors; increases in
warranty and customer support expenses; limitations on manufacturing capacity;
inventory obsolescence; introduction of new distribution and sales channels;
fluctuations in foreign currency exchange rates; delays or changes in
regulatory approval of the Company's systems or those of its customers;
natural disasters or adverse weather; and general economic and political
conditions. In addition, the Company's results of operations have been, and
will continue to be, influenced significantly by competitive factors including
the pricing and availability of, and demand for, competitive or substitute
products. It is likely that, in a future period, the Company's operating
results will not meet the expectations of public market analysts and
investors. In such event, the price of the Company's Common Stock could be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations." In addition, while the
Company's revenues have not been impacted by seasonality to date, the
telecommunications industry historically has been subject to some degree of
seasonality, with lower sales in the first calendar quarter. There can be no
assurance that the Company's business and operating results will not be
adversely affected by such seasonal fluctuations in the future.
 
  The Company's current backlog consists of a relatively small number of
orders for its SpotLight 2000 system. Purchase orders are received and
accepted in advance of shipment and are generally cancelable prior to
shipment. As a result, backlog may not result in revenues and, as of any
particular date, may not be a reliable indicator of sales for any future
period. Furthermore, the Company intends to increase production capacity in
order to reduce the period of time between receipt and shipment of orders.
Thus, the Company does not expect backlog will remain at current levels as a
percentage of sales. Furthermore, due to the many factors affecting decisions
by customers to place orders and the impact of a small number of large orders,
backlog at any given time may fluctuate significantly. Such fluctuations may
adversely affect the Company's business and operating results. See "Business--
Sales, Marketing and Customer Support."
 
  Significant Customer Concentration. The Company has derived a substantial
portion of its revenue from sales of the SpotLight 2000 system to a limited
number of cellular network operators, and the
 
                                       7
<PAGE>
 
Company expects this customer concentration to continue for the foreseeable
future. To date, four customers have accounted for all of the Company's
product sales. For the six months ended June 30, 1998, three customers, St.
Petersburg Telecom, Telefonica Celular and ALLTEL, accounted for approximately
27.4%, 24.0% and 44.2%, respectively, of the Company's net revenues. Due to
the highly concentrated nature of the cellular industry and industry
consolidation, the Company believes that the number of potential customers for
future products, if any, will be small. In this regard, on July 1, 1998,
ALLTEL completed the acquisition of 360(degrees) Communications, another
customer of the Company. Failure by the Company to capture a significant
number of the cellular network operators as customers could have a material
adverse effect on the Company's business and operating results. The Company
expects that a small number of customers will continue to represent a
significant percentage of its total revenues for the foreseeable future,
although the companies that comprise the largest percentage of sales in any
given quarter may change from quarter to quarter. Because of the small size of
the Company's customer base, the loss of any customer or reduced demand for
systems from any customer, could have a material adverse effect on the
Company's business and operating results. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business--
Customers."
 
  Uncertainty of Market Acceptance; Lengthy Sales Cycle. The Company's future
success will depend upon the degree of market acceptance of the Company's
spectrum management solutions. The Company believes that substantially all of
its revenues in the foreseeable future will be derived from sales of its
SpotLight 2000 system. In light of the recent introduction of the SpotLight
2000 system and the rapidly evolving nature of the wireless communications
industry, the Company is unable to predict with any degree of assurance
whether its current or future products will achieve market acceptance. There
can be no assurance that the Company will be able to reduce its reliance on
sales of its SpotLight 2000 system by developing interfaces to other wireless
protocols or base stations manufactured by vendors other than Motorola or
Lucent, or that if developed, such new system versions will achieve market
acceptance. If the SpotLight 2000 system fails to achieve broad market
acceptance, the Company's business and operating results would be materially
adversely affected. See "Business--Metawave Products."
 
  In order for its spectrum management solutions to achieve market acceptance,
the Company must demonstrate to cellular network operators that the systems
provide a spectrum management solution that addresses the cellular network
operators' challenges of capacity, coverage and call quality in a cost-
effective manner. The Company must demonstrate product performance to a
cellular network operator based on such operator's unique network
configuration and specifications. The Company's ability to optimize its
product in any given cell site varies greatly depending on such operator's
specifications and the local geographical terrain. Typically, performance of
the Company's product must be accepted in an initial cell site or cluster of
cell sites prior to completing any additional sales to such cellular network
operator. If the Company's spectrum management solutions are not accepted by
cellular network operators in a timely manner, or at all, the Company's
business and operating results could be materially adversely affected. See "--
Risks Related to Base Station Manufacturers," "--Competition" and "Business--
Metawave Products."
 
  Because the SpotLight 2000 system represents a new approach to increasing
network capacity and affects the key function of a cellular operator's
network, purchase of the SpotLight 2000 system is typically a strategic
decision that requires approval at senior levels of customers' organizations,
significant technical evaluation and a substantial commitment of customers'
personnel, financial and other resources. Historically, the Company has
conducted field trials and has been required to satisfy performance conditions
prior to the completion of a sale. For these and other reasons, the sales
process associated with the purchase of the Company's systems is typically
complex, lengthy and subject to a number of significant risks, including
changes in customers' budgets and approval at senior levels of customers'
organizations and approval by governmental agencies. In addition, given the
regional divisions of many cellular networks, an order from one region does
not necessarily result in subsequent orders from other regions of the same
cellular network without additional trials and substantial selling efforts by
the
 
                                       8
<PAGE>
 
Company. The Company's sales cycle can last up to 18 months or more and varies
substantially from customer to customer. Because of the lengthy sales cycle
and the dependence of the Company's quarterly revenues upon a small number of
orders that represent large dollar amounts, if revenues from any order
forecasted for a particular quarter are not received in that quarter, the
Company's business and operating results could be materially adversely
affected. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business--Sales, Marketing and Customer Support."
 
  Dependence on Cellular Network Operator Capital Spending. The Company
expects that it will derive substantially all of its revenues for the
foreseeable future from sales of its SpotLight 2000 system to cellular network
operators. These operators are located in the United States and foreign
markets. Demand for the Company's products will depend to a significant degree
upon the magnitude and timing of capital spending by cellular network
operators for constructing, rebuilding or upgrading their systems. The capital
spending patterns of cellular network operators depend on a variety of
factors, including access to financing, the status of federal, local and
foreign government regulation and deregulation, changing standards for
cellular technology, overall demand for analog and digital cellular services,
competitive pressures and general economic conditions. In addition, capital
spending patterns in the cellular industry can be subject to some degree of
seasonality, with lower levels of spending in the first calendar quarter,
based on annual budget cycles. Capital spending levels in the U.S. cellular
industry have fluctuated significantly in the past, and there can be no
assurance that such fluctuations will not occur in the future. Any substantial
decrease or delay in capital spending by cellular network operators in the
United States or abroad would have a material adverse effect on the Company's
business and operating results.
 
  Risk of Declining Prices; No Assurance of Cost Reductions. The Company
believes that for its systems to achieve broad market acceptance and to
compete effectively with alternative systems, the Company's average selling
prices must decline. The Company may be subject to price competition from base
station manufacturers which could lower base station prices thereby making the
addition of new base stations a more cost-effective alternative for cellular
network operators seeking increased capacity. In order to achieve lower
average selling prices without adversely affecting gross margins, the Company
must successfully reduce the manufacturing costs of its product through
engineering improvements and economies of scale in production and purchasing.
There can be no assurance that the Company will achieve cost savings at a rate
needed to keep pace with competitive pricing pressures. In addition, if the
cellular industry does not shift to digital protocols that yield higher
product margins for the Company, the Company's gross margins could be
adversely affected in future periods. To the extent that the Company is unable
to reduce costs sufficiently to offset declining average selling prices or the
mix of the Company's sales is comprised substantially of analog-based
technologies, the Company may not achieve positive gross margins. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Research and Development."
 
  Risks Related to Base Station Manufacturers. The Company's product strategy
relies on ensuring the compatibility of the Company's systems with base
stations sold by cellular equipment manufacturers. The Company's product
strategy is competitive in some respects with such manufacturers, and it may
be difficult or impossible for the Company to obtain technical cooperation
from such manufacturers, which may be required to make the Company's systems
compatible with their base stations. The initial version of the SpotLight
system relied on analog technologies and did not require significant
cooperation from such base station manufacturers. As the cellular industry
continues the conversion to digital technologies, increased signal and
connection complexity may require the Company, at a minimum, to obtain
customer or manufacturer cooperation on technical specifications and may
possibly require the Company to obtain manufacturer cooperation to embed the
Company's systems in the base station equipment. There can be no assurance
that the Company will be able to obtain cooperation to make the Company's
products compatible with manufacturers' base stations on reasonable terms, or
at all, and the failure to do so could materially and adversely affect the
Company's business and operating results.
 
                                       9

  Competition. The market for spectrum management solutions is relatively new
but is expected to become increasingly competitive. The Company's products
compete with other smart antenna systems and alternative wireless
infrastructure devices such as repeaters, cryogenic filters and tower-top
amplifiers. The Company believes the principal competitive factors are the
cost-effective delivery of increased capacity, expanded coverage and improved
call quality to cellular network operators. There can be no assurance that the
Company will compete favorably with respect to the foregoing factors.
 
  The Company believes that base station manufacturers, who provide cellular
network capacity through sales of additional base stations, represent a
significant competitive threat to the Company. These manufacturers, including
Ericsson LM Telephone Co. ("Ericsson"), Lucent, Motorola, Nokia Corporation
("Nokia"), Northern Telecom, Ltd. ("Northern Telecom") and Siemens Corporation
("Siemens"), have long-term, established relationships with the cellular
network operators. Deployment of the Company's SpotLight 2000 system by
cellular network operators can improve base station performance, and therefore
may result in fewer sales opportunities for base station manufacturers. Smart
antenna technology represents an area of opportunity for such manufacturers.
The Company believes that certain of these manufacturers are developing smart
antenna systems and are likely to offer smart antenna capabilities in the
future. In addition to having more established relationships with cellular
network operators, these manufacturers have significantly greater financial,
technical, manufacturing, sales, marketing and other resources than the
Company and have significantly greater name recognition for their existing
products and technologies than has the Company.
 
  The Company's current primary direct competitors for spectrum management
solutions are Celwave (a division of Radio Frequency Systems Inc., which is an
affiliate of Alcatel Alsthom S.A.), ArrayComm, Inc. and GEC-Marconi Hazeltine
Corporation. In addition, other companies, such as Raytheon E-Systems,
Watkins-Johnson Company, Texas Instruments Incorporated and ARGOSystems, Inc.
(a subsidiary of The Boeing Company), offer systems that utilize digital
signal processing and interference cancellation techniques to extend cell site
coverage and improve call quality. Several companies offer alternative
technologies such as cryogenic filters, tower-top low noise amplifiers and
repeaters that can be used to provide service in network coverage holes and
improve call quality. The Company may also face competition in the future from
new market entrants offering competing technologies.
 
  The Company believes that its ability to compete in the future will depend
in part on a number of competitive factors outside its control, including the
development by others of products that are competitive with the Company's
products and the price at which others offer comparable products. To be
competitive, the Company will need to continue to invest substantial resources
in engineering, research and development and sales and marketing. There can be
no assurance that the Company will have sufficient resources to make such
investments or that the Company will be able to make the technological
advances necessary to remain competitive. Accordingly, there can be no
assurance that the Company will be able to compete successfully in the future.
See "Business--Competition."
 
  Management of Growth; New Management Team. The growth of the Company's
operations has placed, and is expected to continue to place, a significant
strain on the Company's financial and management resources as well as its
product design, manufacturing, sales and customer support capabilities. In May
1998, the Company moved to significantly larger facilities to accommodate the
Company's expanded research and development and manufacturing needs. As the
Company expands its operations to multiple locations, including
internationally, management of the Company's operations will become
increasingly complex. To manage its anticipated growth, the Company must,
among other things, continue to implement and improve its operational,
financial and management information systems, hire and train additional
qualified personnel, continue to expand and upgrade core technologies and
effectively manage multiple relationships with various customers, suppliers
and other third parties. The Company recently upgraded its financial and
accounting software to an enterprise resource planning software package that
integrates manufacturing, finance and sales order management. The Company
anticipates that additional upgrades to its management information systems
will be required in the near future to address
 
                                      10
<PAGE>
 
the expected increased volume and complexity of the Company's transactions.
There can be no assurance that the Company will successfully integrate the
newly purchased software with its existing systems or that the integration of
the new systems will not cause unanticipated system disruptions, slower
response times, degradation in levels of performance or reliability, impaired
quality of production, and delays in reporting accurate financial information.
Failure to successfully implement and integrate these systems, procedures and
controls to effectively manage the Company's growth in operations in a timely
manner could have a material adverse effect on the Company's business and
operating results.
 
  From January 1, 1997 to June 30, 1998, the Company expanded from 91 to 200
employees. A majority of the Company's executive officers joined the Company
within the last 18 months and many of these officers have no prior experience
as executive officers of publicly traded companies. The Company's new
employees include the Chief Executive Officer and Chief Financial Officer as
well as a number of other key managerial, technical and operations personnel
who have not yet been fully integrated into the Company, and the Company
expects to add additional key personnel in the near future. There can be no
assurance that the Company's current and planned personnel will be adequate to
support the Company's future operations, that management will be able to hire,
train, retain, motivate and manage required personnel or that Company
management will be able to successfully identify, manage and exploit existing
and potential market opportunities. If the Company is unable to manage growth
effectively, its business and operating results will be materially adversely
affected.
 
  Rapid Technological Change and Requirement for Frequent New Product
Introductions. The Company's future success will depend in large part on its
ability to develop new products designed to operate with different digital
technologies such as CDMA and GSM as well as across other principal
manufacturer base stations. There can be no assurance that the Company will
successfully develop and introduce such products in a timely manner. In this
regard, the Company is currently conducting trials of its recently developed
dual-mode AMPS/CDMA based SpotLight 2000 system. There can be no assurance
that the trials will be successful or that the cellular network operators will
accept the product.
 
  The market for the Company's current products and planned future products is
subject to rapid technological change, frequent new product introductions and
enhancements, product obsolescence, changes in customer requirements and
evolving industry standards. To be competitive, the Company must successfully
develop, introduce and sell new products or product enhancements that respond
to changing customer requirements on a timely and cost-effective basis. The
Company's success in developing new and enhanced products will depend on a
variety of factors, many of which are beyond the Company's control. Such
factors include the timely and efficient completion of system design; the
timely and efficient implementation of assembly, calibration and test
processes; sourcing of components; the development and completion of related
software; the reliability, cost and quality of new products; the degree of
market acceptance; and the development and introduction of competitive
products by competitors. The Company has experienced and may continue to
experience delays in development and introduction of products. In addition,
the Company may be required to obtain licenses to intellectual property rights
held by third parties to develop new products or product enhancements and
there can be no assurance that such licenses will be available on acceptable
terms, if at all. The inability of the Company to introduce in a timely manner
new products or product enhancements that contribute to sales could have a
material adverse effect on the Company's business and operating results. In
addition, changes in manufacturing operations to incorporate new products and
processes could cause disruptions in production of existing products, which,
in turn, could adversely affect customer relationships and the market's
acceptance of the Company's products, and have a material adverse effect on
the Company's business and operating results. See "Business--Research and
Development" and "--Manufacturing."
 
  Limited Manufacturing Experience; No Assurance of Successful Expansion of
Operations. The Company's manufacturing operations consist primarily of
supplier and commodity management and assembling finished goods from
components and subassemblies purchased from outside suppliers.
 
                                      11
<PAGE>
 
Because the Company configures each SpotLight 2000 system to meet customer
specifications, the Company's ability to achieve manufacturing efficiencies by
assembling products before orders are received is limited. The Company intends
to expand its manufacturing capacity by purchasing additional equipment,
hiring additional personnel, further developing its proprietary test software
to improve productivity, increasing the efficiency of its production
processes, and, in certain instances, subcontracting additional assembly,
calibration and testing processes. If the Company is to achieve its
objectives, it will also be required to significantly expand its sales,
marketing and customer support capabilities. The Company intends to
subcontract a significant portion of its field installation work to third
parties. There can be no assurance that the Company will be successful in
identifying subcontractors with adequate experience or will be able to retain
experienced subcontractors on acceptable terms, if at all, or that the Company
will effectively manage multiple subcontractors working on multiple
installation projects. Due to the Company's limited experience with large
scale operations, there can be no assurance that the Company will be able to
develop internally, or contract with third parties for, additional
manufacturing capacity and field support on acceptable terms, that it will be
able to maintain the quality of its products as production increases, or that
it will develop the administrative and other structures necessary to support
expanded operations. The Company's success depends on its ability to
significantly increase its production capacity and field support.
 
  The Company's arrangements with its customers typically require that orders
be shipped not more than 90 days after the order. There can be no assurance
that the Company will be able to increase its production capacity at an
acceptable cost or rapidly enough to fill its orders. The failure to assemble
and ship products on a timely basis could damage relationships with customers
and result in cancellation of orders or lost orders, which would have a
material adverse effect on the Company's business and operating results. See
"Business--Manufacturing."
 
  The Company currently manufactures all of its products in a single facility
in Redmond, Washington. If the Company's facilities or the facilities of its
suppliers were incapable of operating, even temporarily, or were unable to
operate at or near full capacity for any extended period, the Company's
business and operating results could be materially adversely affected. In
connection with its capacity expansion, the Company may seek to develop one or
more additional manufacturing facilities, including, possibly, facilities
located outside the Redmond, Washington area. Although there can be no
assurance that such a facility will be added, the operation of any such
facility would significantly increase the complexity of the Company's
operations.
 
  No Assurance of Product Quality, Performance and Reliability. Manufacturing
and installing the Company's SpotLight 2000 system is a complex process and
requires significant expertise. Because of the Company's limited operating
history and the short time that the SpotLight 2000 system has been in
production, the Company's personnel have limited experience in installing and
integrating the Company's systems. If the Company were unable to successfully
and efficiently deploy its systems in the field, or were unable to attract and
retain the required trained technicians to deploy products in the field, the
Company's business and operating results would be materially adversely
affected.
 
  The Company's ability to achieve future revenue growth will depend in
significant part upon its ability to obtain and fulfill orders from, maintain
good relationships with and provide support to existing and new customers, and
to manufacture products on a timely and cost-effective basis to meet stringent
customer performance requirements and shipment and delivery dates. Because of
the Company's limited operating history and the short time that the SpotLight
2000 system has been in production, there can be no assurance that problems
will not occur with respect to the integration, quality, performance and
reliability of the Company's systems. If such problems occur, the Company
could experience significant warranty claims or increased costs or delays in,
cancellations of, or rescheduling of orders or shipments, any of which could
have a material adverse effect on the Company's business and operating
results.
 
  Dependence on Attraction and Retention of Key Personnel. The Company's
future operating results depend in significant part upon the continued
contributions of each of its key technical and senior
 
                                      12
<PAGE>
 
management personnel, including Douglas O. Reudink, the Company's founder and
Chief Technical Officer, each of whom would be difficult to replace, as there
is a limited number of people with the necessary skills and experience to
develop and manufacture the Company's products. The Company has not entered
into employment agreements with any of its employees other than severance
arrangements with Richard Henderson, Robert H. Hunsberger, Vito E. Palermo and
Dr. Reudink. See "Management--Severance Arrangements." Except for Dr. Reudink,
the Company has not entered into any non-competition agreements with any of
its employees. The Company does not maintain key-man life insurance on any of
its key technical or senior management personnel. In addition, the Company
anticipates that it will need additional management personnel if it is to be
successful in increasing production capacity and the scale of its operations.
There can be no assurance that it will be able to obtain and retain such
personnel on acceptable terms.
 
  The Company's future operating results also depend in significant part upon
its ability to attract and retain qualified engineering, manufacturing,
quality assurance, sales, marketing and customer support personnel.
Competition for such personnel, particularly qualified engineers, is intense.
The Company has experienced difficulties in recruiting sufficient numbers of
qualified engineers, and there can be no assurance that the Company will be
successful in attracting or retaining such personnel. There may be only a
limited number of persons with the requisite skills to serve in these
positions, particularly in the market where the Company is located, and it may
be increasingly difficult for the Company to hire such personnel over time. As
the Company's product development efforts relate to cellular standards that
are widely deployed in foreign countries, the Company may be required to
recruit foreign engineers who have expertise in such standards. Current U.S.
immigration laws restrict the Company's ability to hire foreign employees,
which could have a material adverse effect on the Company's product
development efforts. The loss of any key employee, the failure of any key
employee to perform in his or her current position, the Company's inability to
attract and retain skilled employees as needed or the inability of the
officers and key employees of the Company to expand, train and manage the
Company's employee base could materially adversely affect the Company's
business and operating results. See "Business--Employees" and "Management."
 
  Sole Source Suppliers; Dependence on Key Suppliers. Certain parts and
components used in the Company's products, including linear power amplifiers
supplied by Powerwave Technologies, Inc. ("Powerwave") are presently only
available from a sole source. In addition, the Company is currently dependent
upon Sanmina Corporation ("Sanmina") as the primary source for the supply of
the Company's printed circuit board assemblies. Certain other parts and
components used in the Company's products are available from a limited number
of sources. The Company's reliance on these sole or limited source suppliers
involves certain risks and uncertainties, including the possibility of a
shortage or the discontinuation of certain key components and reduced control
over delivery schedules, manufacturing capability, quality and cost. Any
reduced availability of such parts or components when required could
materially impair the Company's ability to manufacture and deliver its
products on a timely basis and result in the cancellation of orders, which
could have a material adverse effect on the Company's business and operating
results. In addition, the purchase of certain key components involves long
lead times and, in the event of unanticipated increases in demand for the
Company's products, the Company may be unable to obtain such components in
sufficient quantities to meet its customers' requirements. The Company does
not have guaranteed supply arrangements with any of its sole or limited source
suppliers, does not maintain an extensive inventory of parts or components and
customarily purchases sole or limited source parts and components pursuant to
purchase orders. Business disruptions, quality issues, production shortfalls
or financial difficulties of a sole or limited source supplier could
materially and adversely affect the Company by increasing product costs, or
eliminating or delaying the availability of such parts or components. In such
event, the inability of the Company to develop alternative sources of supply
quickly and on a cost-effective basis could materially impair the Company's
ability to manufacture and deliver its products on a timely basis and could
have a material adverse effect on its business and operating results. See
"Business--Manufacturing."
 
                                      13

  Dependence on Growth of Cellular Communications Market. The future operating
results of the Company will depend to a significant extent upon the continued
growth and increased availability and acceptance of cellular communications
services internationally and in the United States. There can be no assurance
that the volume and variety of cellular services or the markets for and
acceptance of such services will grow, or that such services will create a
demand for the Company's systems. If the cellular communications market fails
to grow, or grows more slowly than anticipated, the Company's business and
operating results may be materially adversely affected.
 
  The cellular communications industry has developed different technologies
and standards based on the type of service provided and geographical region.
There is uncertainty as to whether all existing cellular technologies will
continue to achieve market acceptance in the future. If a digital technology
for which the Company develops a product is not widely adopted, the potential
size of the market for the Company's product will be limited, and the Company
may not recover the cost of development of such product. Further, the Company
may not be able to re-direct its development efforts toward digital cellular
technologies that do sustain market acceptance in a timely manner, which would
have a material adverse effect on the Company's business and operating
results.
 
  Need for Additional Capital. The Company requires substantial working
capital to fund its business and expects to use a portion of the net proceeds
of this offering to fund its operating losses. The Company has experienced
negative cash flow from operations since inception and expects to continue to
experience significant negative cash flow from operations for the foreseeable
future. The Company's future capital requirements will depend upon many
factors, including the success or failure of the Company's efforts to expand
its production, sales and marketing efforts, the status of competitive
products, and the requirements of the Company's efforts to develop new
products and product enhancements. The Company believes that current capital
resources, together with the estimated net proceeds from this offering, are
adequate to fund its operations for at least twelve months. Thereafter, the
Company may be required to raise additional capital. There can be no assurance
that additional financing will be available to the Company on acceptable
terms, if at all, or that such financing may not result in further dilution to
existing stockholders. The Company may be required to obtain funds through its
arrangements with partners or others that may require the Company to
relinquish rights to certain of its technologies or potential products or
other assets. If adequate funds are not available, the Company may be required
to delay, scale back or eliminate expansion of its production, administration
or research and development programs. Any inability to obtain needed financing
by the Company could have a material adverse effect on its business and
operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  Risks Associated with International Markets. Approximately 51.5% of net
revenue for the six months ended June 30, 1998 was from sales of the Company's
SpotLight 2000 system to customers located outside of the U.S. For the quarter
ended June 30, 1998, 39.0% of net revenue was related to the sale of the
SpotLight 2000 system to a single customer in Paraguay.
 
  Although the Company believes that international sales will decline as a
percentage of net revenues over time, the Company anticipates that
international sales will continue to account for a significant portion of its
revenue for the foreseeable future. To date, the Company's international sales
have been denominated in U.S. dollars; however, in the future a portion of the
Company's international sales may be denominated in foreign currencies. The
Company does not currently engage in foreign currency hedging transactions as
all sales to date have been in U.S. dollars. However, if a material amount of
future sales are denominated in foreign currency, a decrease in the value of
foreign currencies relative to the United States dollar could result in losses
from such transactions. In such event, the Company might seek to limit its
exposure to foreign currency transactions by engaging in hedging activities.
There can be no assurance that any such activity would be successful in
avoiding exchange-related losses. With respect to the Company's international
sales that are United States dollar denominated, an increase in the relative
value of the U.S. dollar could make the Company's systems less price-
competitive, or could cause
 
                                      14
<PAGE>
 
customers to renegotiate prices for subsequent purchases, both of which could
have a material adverse effect upon the Company's business and operating
results. Additional risks inherent in the Company's international business
activities include delays due to customs inspections and procedures, changes
in regulatory requirements, tariffs and other trade barriers, political and
economic instability in developing countries, difficulties in staffing and
managing foreign operations, difficulties in managing distributors,
potentially adverse tax consequences, the burden of complying with a wide
variety of complex foreign laws and treaties, difficulties in obtaining
necessary equipment authorizations and the possibility of difficulty in
accounts receivable collections. Distribution and sales agreements entered
into with foreign customers may be governed by foreign laws which may differ
significantly from U.S. laws. Therefore, the Company may be limited in its
ability to enforce its rights under such agreements and to collect damages, if
awarded. There can be no assurance that any of these factors will not have a
material adverse effect on the Company's business and operating results.
 
  To date, the Company has sold its products directly to cellular network
operators. In the future, it may be desirable to establish distribution
relationships in the international market. The Company has not established any
distribution relationships and there can be no assurance that the Company will
be able to establish such distribution relationships on acceptable terms, if
at all. The failure to establish any distribution relationships, or the
failure to implement an alternative distribution strategy in a cost-effective
manner, or any delays in establishing such channels, could reduce or eliminate
the Company's opportunity to sell its systems in foreign markets, which could
have a material adverse effect on the Company's business and operating
results. Further, if the Company is unable to produce and sell its systems at
margins that permit it to provide distribution partners with a sufficient
financial incentive to distribute the Company's systems without adversely
affecting the Company's profitability, the Company's distribution strategy
could adversely affect the Company's business and operating results.
 
  Risks Associated with Potential Acquisitions. The Company intends to review
acquisition prospects that would complement its existing product offerings,
augment its market coverage or enhance its technological capabilities.
Although the Company has no current agreements or negotiations underway with
respect to any material acquisitions, the Company may make acquisitions of
businesses, products or technologies in the future. However, there can be no
assurance that the Company will be able to locate suitable acquisition
opportunities. Future acquisitions by the Company could result in potentially
dilutive issuances of equity securities, large write-offs, the incurrence of
debt and contingent liabilities or amortization expenses related to goodwill
and other intangible assets, any of which could materially adversely affect
the Company's operating results or the price of the Company's Common Stock.
Further, acquisitions entail numerous operational risks, including
difficulties in the assimilation of operations, potential loss of key
employees, technologies, products and the information systems of the acquired
companies, diversion of management's attention from other business concerns
and risks of entering geographic and business markets in which the Company has
no or limited prior experience. Since the Company has not made any material
acquisitions in the past, no assurance can be given as to the ability of the
Company to successfully integrate any businesses, products, technologies or
personnel that might be acquired in the future, and the failure of the Company
to do so could have a material adverse effect on the Company's business and
operating results.
 
  Government Regulation. Wireless communications are subject to extensive
regulation by foreign and U.S. laws and international treaties. The Company's
systems must conform to certain international and domestic regulations
established to, among other things, avoid interference among users of
frequencies. In order for the Company's products to be used, regulatory
approval must be obtained. This governmental approval process frequently
involves substantial delay which could result in the cancellation,
postponement or rescheduling of orders by the Company's customers, which in
turn may have a material adverse effect on the sale of systems by the Company
to such customers. The Company believes that its SpotLight 2000 system
currently complies with all applicable U.S. and foreign regulations in
countries in which its sales are material. However, changes in these
regulations, the need to comply with regulations
 
                                      15
<PAGE>
 
in additional countries in the event of sales to cellular network operators in
those countries, or a failure to obtain necessary approvals or permits in
connection with sales to cellular network operators in a country could
preclude sales of the Company's products to such operators or could require
the Company to change the features of its SpotLight 2000 system and thereby
incur substantial costs and experience delays in system installation or
operation.
 
  The regulatory environments in which the Company operates are subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly affect the Company's
operations by increasing or reallocating the amount of spectrum available to
wireless operators, restricting network development efforts by the Company's
customers or end users, making current systems obsolete, increasing the
opportunity for additional competition or requiring the Company's products to
comply with new regulations. Any such regulatory changes could have a material
adverse effect on the Company's business and operating results. The Company
might deem it necessary or advisable to modify its systems to operate in
compliance with such regulations. Such modifications could be expensive and
time-consuming. See "--Risks Associated with International Markets" and
"Business--Government Regulation."
 
  Uncertainty Regarding Protection of Intellectual Property. The Company
relies on a combination of patent, trade secret, copyright and trademark
protection, nondisclosure agreements and other measures to protect its
proprietary rights. The Company currently has eight issued U.S. patents and 25
pending U.S. patent applications. The Company's future success will depend in
large part on its ability to obtain patent protection in the U.S. and foreign
markets, to defend patents once obtained, to maintain trade secrets and to
operate without infringing upon the patents and proprietary rights of others.
The patent positions of companies in the worldwide wireless communications
industry, including the Company, are generally uncertain and involve complex
legal and factual questions. There can be no assurance that any issued patents
owned by or licensed to the Company will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company. Further, there can be no assurance that patents
will issue from any patent applications or that, if patents do issue, the
claims allowed would be sufficiently broad to protect the Company's
technology. In addition, there can be no assurance that patents issued in the
U.S. will receive corresponding patent protection in foreign markets or that
the Company will pursue similar patent protection in all foreign markets.
 
  Patents and patent applications relating to products used in the wireless
communications industry are numerous and current and potential competitors and
other third parties may have filed or may in the future file applications for,
or may have been issued or in the future may be issued, patents or may obtain
additional proprietary rights relating to products used or proposed to be used
by the Company. The Company may not be aware of all patents or patent
applications that may materially affect the Company's ability to make, use or
sell any current or future products. From time to time, third parties have
asserted patent, copyright and other intellectual property rights to
technologies that are important to the Company. The Company expects that it
will increasingly be subject to infringement claims as the number of products
and competitors in the spectrum management market grows and the functionality
of products overlaps. Third parties may assert infringement claims against the
Company in the future, and such assertions could result in costly litigation
or require the Company to obtain a license to intellectual property rights of
such parties. There can be no assurance that any such licenses would be
available on terms acceptable to the Company, if at all. Any failure to obtain
a license from any third party asserting claims in the future or defense of
any third party lawsuit could have a material adverse effect on the Company's
business and operating results.
 
  The Company also relies on unpatented trade secrets to protect its
proprietary technology, and there can be no assurance that others will not
independently develop or otherwise acquire the same or substantially
equivalent technologies or otherwise gain access to the Company's proprietary
technology or disclose such technology or that the Company can ultimately
protect its rights to such unpatented
 
                                      16
<PAGE>
 
proprietary technology. Further, third parties may obtain patent rights to
such unpatented trade secrets, which patent rights could be used to assert
infringement claims against the Company. The Company also relies on
confidentiality agreements with its employees, suppliers, consultants and
customers to protect its proprietary technology. There can be no assurance
that these agreements will not be breached, that the Company would have
adequate remedies for any breach or that the Company's trade secrets will not
otherwise become known to or be independently developed by competitors.
Failure to obtain or maintain patent and trade secret protection, for any
reason, could have a material adverse effect on the Company's business and
operating results. See "Business--Intellectual Property."
 
  Year 2000 Compliance. Many existing computer systems and applications, and
other control devices, use only two digits to identify a year in the date
field, without considering the impact of the upcoming change in the century.
As a result, such systems and applications could fail or create erroneous
results unless corrected so that they can process data related to the year
2000. The Company relies on its systems, applications and devices in operating
and monitoring all major aspects of its business, including financial and
accounting systems, customer services, networks and telecommunications
equipment and end products. The Company also relies, directly and indirectly,
on external systems of business enterprises such as customers, suppliers,
creditors, financial organizations, and of governmental entities, both
domestic and international, for accurate exchange of data. The Company's
current estimate is that the costs associated with the year 2000 issue, and
the consequences of incomplete or untimely resolution of the year 2000 issue,
will not have a material adverse effect on the result of operations or
financial position of the Company in any given year. However, despite the
Company's efforts to address the year 2000 impact on its internal systems, the
Company has not fully identified such impact or whether it can resolve it
without disruption of its business and without incurring significant expense.
In addition, even if the internal systems of the Company are not materially
affected by the year 2000 issue, the Company could be affected through
disruption in the operation of the enterprises with which the Company
interacts.
 
  No Prior Public Market; Possible Volatility of Stock Price. Prior to this
offering, there has been no public market for the Common Stock. The initial
public offering price of the Common Stock will be determined by negotiations
between the Company and the Representatives of the Underwriters and may not be
indicative of the market price for the Common Stock in the future. See
"Underwriting" for a discussion of the factors considered in determining the
initial public offering price. There can be no assurance that an active
trading market will develop or be sustained after this offering. The Company
believes that factors such as announcements of developments related to the
Company's business, announcements of technological innovations or new products
or enhancements by the Company or its competitors, sales by competitors,
including sales to the Company's customers, sales of the Company's Common
Stock into the public market, including by members of management, developments
in the Company's relationships with its customers, partners, distributors and
suppliers, shortfalls or changes in revenues, gross profits, earnings or
losses or other financial results from analysts' expectations, regulatory
developments, fluctuations in results of operations, and general conditions in
the Company's market, of the markets served by the Company's customers, or the
economy could cause the price of the Company's Common Stock to fluctuate,
perhaps substantially. In addition, in recent years the stock market, in
general, and the market for shares of small capitalization and technology
stocks in particular, have experienced extreme price fluctuations, which have
often been unrelated to the operating performance of affected companies. There
can be no assurance that the market price of the Company's Common Stock will
not experience significant fluctuations in the future, including fluctuations
that are unrelated to the Company's performance. Such fluctuations could
materially adversely affect the market price of the Company's Common Stock.
 
  Broad Discretion of Management to Allocate Offering Proceeds. The Company
will use approximately $16.2 million to repay one-half of the outstanding
principal and estimated interest on its 13.75% Senior Secured Bridge Notes and
the remaining $31.8 million for working capital and other general corporate
purposes including working capital to fund anticipated operating losses and
capital
 
                                      17
<PAGE>
 
expenditures. The Company may, when and if the opportunity arises, use a
portion of the proceeds to acquire or invest in complimentary business,
products or technologies. The Company's management will have broad discretion
to allocate the remaining proceeds of this offering, and the amounts actually
expended for each use listed above may vary significantly depending on a
number of factors, including the amount of future revenues, the amount of cash
generated or used by the Company's operations, the progress of the Company's
product development efforts, technological advances, and the status of
competitive products. There can be no assurance that the proceeds will be
utilized in a manner that the stockholders deem optimal, or that the proceeds
can or will be invested to yield a significant return.
 
  Shares Eligible for Future Sale After the Offering. Sales of substantial
amounts of Common Stock in the public market after this offering or the
anticipation of such sales could materially affect then prevailing market
prices. All of the 5,000,000 shares offered hereby may be resold immediately
in the public market. Beginning 90 days after the date of this Prospectus,
approximately 298,155 additional shares may be resold in the public market.
Beginning 180 days after the date of this Prospectus, upon expiration of pre-
existing lock-up agreements and lock-up agreements between the representatives
of the Underwriters and officers, directors and certain stockholders of the
Company, approximately 915,774 total shares will be eligible for sale without
restriction under Rule 144(k) or Rule 701 under the Securities Act of 1933, as
amended (the "Securities Act"), and 14,941,348 shares will be eligible for
sale subject to compliance with the restrictions of Rule 144 and, under
certain circumstances, Rule 701 under the Securities Act. Any early release of
the lock-up agreement by the Underwriters, which, if granted, could permit
sales of a substantial number of shares and could adversely affect the trading
price of the Company's shares, may not be accompanied by an advance public
announcement by the Company. Holders of approximately 15,338,305 shares of
Common Stock and the holders of the Note Warrants (the "Registrable
Securities") also will have the right to include such shares in any future
registration of securities effected by the Company and to require the Company
to register their shares for future sale, subject to certain exceptions. See
"Description of Securities--Registration Rights of Certain Holders" and
"Shares Eligible for Future Sale."
 
  Control by Existing Stockholders. Following the completion of this offering,
members of the Board of Directors and the officers of the Company, together
with entities that may be deemed affiliates of or related to such persons or
entities, will beneficially own approximately 58.4% (approximately 56.5% on a
fully diluted basis, assuming the exercise of all warrants and vested and
unvested options held by such persons and outstanding at June 30, 1998) of the
outstanding shares of Common Stock of the Company. Accordingly, these
stockholders are able to significantly influence the election of the members
of the Company's Board of Directors and significantly influence the outcome of
corporate actions requiring stockholder approval, such as mergers and
acquisitions. This level of ownership may have a significant effect in
delaying, deferring or preventing a change in control of the Company and may
adversely affect the voting and other rights of other holders of Common Stock.
See "Management--Directors and Executive Officers," "--Principal Stockholders"
and "Description of Capital Stock."
 
  Effect of Certain Charter and Bylaw Provisions. Certain provisions of the
Company's Restated Certificate of Incorporation and Bylaws may have the effect
of making it more difficult for a third party to acquire or of discouraging a
third party from attempting to acquire, control of the Company. Such
provisions could limit the price that certain investors might be willing to
pay in the future for shares of the Company's Common Stock. Certain of these
provisions allow the Company to issue up to 15,000,000 shares of Preferred
Stock and fix the rights and preferences thereof without any vote or further
action by the stockholders, eliminate the right of stockholders to act by
written consent without a meeting and eliminate cumulative voting in the
election of directors. The rights of holders of Common Stock will be subject
to, and may be adversely affected by, the rights of holders of any Preferred
Stock that may be issued in the future. These provisions may make it more
difficult for stockholders to take certain corporate actions and could have
the effect of delaying or preventing a change in control of the Company.
Certain provisions of Delaware law and Washington law applicable to the
Company could also delay or make more difficult a merger, tender offer or
proxy contest involving the Company. Such provisions include Section
 
                                      18
<PAGE>
 
203 of the Delaware General Corporation Law, which prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years unless certain conditions are met, and
Chapter 23B.19 of the Washington Business Corporation Act, which prohibits a
corporation operating in Washington from engaging in certain significant
business transactions with a person or group of persons who beneficially own
10% of the voting securities of such corporation for a period of five years
unless certain conditions are met. After the five-year period, such
significant business transaction must still comply with certain fair price
provisions of such statute. See "Management" and "Description of Securities--
Anti-Takeover Provisions of Delaware and Washington Law and Charter
Documents."
 
  Immediate and Substantial Dilution. Investors in Common Stock in this
offering will experience immediate dilution in the net tangible book value of
their shares. At the initial public offering price of $10.50 per share,
dilution to new investors will be $8.00 per share. Additional dilution will
occur upon exercise of outstanding stock options and warrants. If the Company
seeks additional capital in the future, the issuance of shares or convertible
debt to obtain such capital may lead to further dilution. See "Dilution."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale and issuance of the 5,000,000
shares of Common Stock offered hereby, at an assumed initial public offering
price of $10.50 per share, are estimated to be $48.0 million ($55.3 million if
the Underwriters' over-allotment option is exercised in full). The Company
will use approximately $16.2 million of the net proceeds to repay one-half of
the outstanding principal and estimated accrued interest on its 13.75% Senior
Secured Bridge Notes and the remaining proceeds for general corporate
purposes, including working capital to fund anticipated operating losses and
capital expenditures. The Company may, when and if the opportunity arises, use
a portion of the proceeds to acquire or invest in complimentary business,
products or technologies. The Company's management will have broad discretion
to allocate the remaining proceeds of this offering, and the amounts actually
expended for each use listed above may vary significantly depending on a
number of factors, including the amount of future revenues, the amount of cash
generated or used by the Company's operations, the progress of the Company's
product development efforts, technological advances, and the status of
competitive products. Pending such uses, the Company intends to invest such
funds in short-term, investment grade, interest-bearing obligations. See

                                   DILUTION
 
  As of June 30, 1998, the Company had a pro forma net tangible book value of
approximately $4.9 million, or $0.30 per share of Common Stock. Pro forma net
tangible book value represents total tangible assets less total liabilities
divided by the pro forma number of shares of Common Stock outstanding,
assuming the conversion of convertible and redeemable Preferred Stock to
Common Stock and the conversion of Preferred Stock warrants to Common Stock
warrants. Without taking into account any other changes in the pro forma net
tangible book value after June 30, 1998, other than to give effect to the
receipt by the Company of the net proceeds from the sale of the 5,000,000
shares of Common Stock offered by the Company hereby at an assumed initial
public offering price of $10.50 per share, and after deducting estimated
underwriting discounts and commissions and estimated offering expenses payable
by the Company, the pro forma net tangible book value at June 30, 1998 would
have been approximately $52.9 million, or $2.50 per share. This represents an
immediate increase in net tangible book value of $2.20 per share to existing
stockholders and an immediate dilution of $8.00 per share to new investors
purchasing shares in this offering. The following table illustrates this per
share dilution:

OVERVIEW
 
  Metawave designs, develops, manufactures and markets spectrum management
solutions for the wireless communications industry. Metawave's spectrum
management solutions, consisting of smart antenna systems, applications
software and engineering services, enable cellular network operators to
increase overall network capacity, reduce network operation costs, better
manage network infrastructure and stimulate end user demand through improved
system quality. Using its proprietary technologies, the Company has developed
products that address the capacity, coverage, and call quality problems faced
by cellular network operators.
 
  The Company was incorporated in January 1995. Net revenue since inception
has been attributable to an engineering consulting contract in 1996, services
rendered by the Company's Network Services division during 1997 and sales of
the SpotLight 2000 system during the six months ended June 30, 1998. The
Company's Network Services division was discontinued during the first quarter
of 1998. Since inception, the Company has incurred significant losses and as
of June 30, 1998, had an accumulated deficit of $50.1 million.
 
  From inception through June 30, 1998, the Company's operating activities
related primarily to conducting research and development, building market
awareness, recruiting management and technical personnel and building an
operating infrastructure. In 1997, the Company hired a new Chief Executive
Officer and a new Chief Financial Officer and added managerial personnel in
the engineering, product management, sales and administrative areas. Shipment
for commercial sale of the SpotLight 2000 system began late in the fourth
quarter of 1997. Since launching its SpotLight 2000 system, the Company has
increased operating expenditures in an effort to increase sales and expand
manufacturing capacity. In light of the progression of the Company from a
development stage to an operating stage during the past two years, the Company
believes that period to period comparisons of its financial results should not
be relied upon as an indicator of future performance.
 
  There are two components of net revenue attributable to the SpotLight 2000
system, product revenue and service revenue. Product revenue is comprised of
both the sale of hardware and the licensing of software. Service revenue is
derived from installation, consulting services and maintenance contracts. The
Company believes that substantially all of its revenues in the foreseeable
future will be derived from sales of its SpotLight 2000 system. Sales cycles
can be lengthy and the related contracts typically include performance
specifications and customer acceptance conditions in connection with the
initial sale of each system to each customer. The Company recognizes net
revenue when the product has been shipped and all customer acceptance
conditions have been satisfied. The Company recognizes service revenue when
the services have been performed. If the Company does not satisfy conditions
in such contracts or satisfaction of conditions is delayed, revenues in any
particular period could fall significantly below the Company's expectations.
Contract terms, including pricing and acceptance criteria, will typically vary
depending upon the order, and the nature and extent of installation and
consulting services. Consequently, net revenue may vary from quarter to
quarter depending on the length of the sales cycle
 
                                      24
<PAGE>
 
and the applicable contract terms. If anticipated sales and shipments in any
quarter do not occur when expected, expenses and inventory levels could be
disproportionately high.
 
  Cost of sales typically consists of material components, manufacturing
assembly and test, and overhead expenses. The Company believes that for its
SpotLight 2000 system to achieve broad market acceptance and compete
effectively with alternative systems, the Company's average selling prices
must decline. In order to achieve lower average selling prices without
adversely affecting gross profits, the Company must successfully reduce the
manufacturing costs of its product through engineering improvements and
economies of scale in production and purchasing. There can be no assurance,
however, that the Company will be able to achieve cost savings at a rate
necessary to keep pace with competitive pricing pressures. The Company expects
that its gross margins will continue to be affected by a variety of other
factors, including increased investment in manufacturing facilities and
equipment, changes in labor costs, changes in product mix due to a shift from
analog-only to analog/CDMA dual-mode system sales, changes in warranty expense
or inventory obsolescence, increased sourcing and changes in prices of
components and subassemblies from third party manufacturers and increased
price competition.
 
  The Company's manufacturing operations consist primarily of supplier and
commodity management and assembling finished goods from components and
subassemblies purchased from outside suppliers. In May 1998, the Company moved
to significantly larger facilities to accommodate the Company's current
research, development and manufacturing needs in the near term. The Company
plans to further expand its manufacturing capacity in the future if and to the
extent the Company's products achieve market acceptance and demand increases.
If such expansion occurs, substantial investments in additional capital
equipment and the recruiting and training of additional personnel will be
required, which may include increased sourcing of components from third
parties as well as increased system integration and full-configuration testing
or investment in additional manufacturing facilities. See "Risk Factors--
Limited Manufacturing Experience; No Assurance of Successful Expansion of
Operations."
 
  The Company recently upgraded its financial and accounting software to an
enterprise resource planning software package that integrates manufacturing,
finance and sales order management. The Company anticipates that additional
upgrades to its management information systems will be required in the near
future to address the expected increased volume and complexity of the
Company's transactions. See "Risk Factors--Management of Growth; New
Management Team."
 
  Research and development expense consists principally of salaries and
related personnel expenses, consultant fees and prototype expenses related to
the design, development, testing and enhancement of the Company's SpotLight
2000 system. As of June 30, 1998, all research and development costs had been
expensed as incurred. The Company believes that continued investment in
research and development is critical to attaining its strategic product and
cost reduction objectives and, as a result, expects these expenses to increase
significantly in absolute dollars in the future. Sales and marketing expense
consists of salaries, sales commissions and related expenses for personnel
engaged in marketing, sales and field service support functions, as well as
promotional expenditures. The Company expects sales and marketing expense to
increase significantly in absolute dollars in the future. General and
administrative expense consists primarily of salaries and personnel related
expenses, recruiting expenses, professional fees and other general corporate
expenses. The Company expects general and administrative expense to increase
in absolute dollars as the Company adds personnel and incurs additional costs
related to the growth of its business and operation as a public company.
 
  The revenue and profit potential of the Company's business is unproven and
the Company's limited operating history makes its future operating results
difficult to predict. The Company believes that its growth and future success
will be dependent upon the broad acceptance of the SpotLight 2000 system by
cellular network operators. Because the SpotLight 2000 system was only
recently introduced, the Company is unable to predict with any degree of
certainty whether it will achieve market acceptance.

There can be no assurance that the Company will ever achieve profitability or
significant revenues on a quarterly or an annual basis. Because of the limited
size of the Company's customer base and the large size of customer orders,
revenues derived from a small number of customers will likely represent a
significant portion of revenue in any given period. Thus, a decrease in demand
for the Company's systems from any customer for any reason is likely to result
in significant periodic fluctuations in revenue. Due to the highly
concentrated nature of the cellular industry, the Company believes that the
number of potential customers for future products, if any, will be small.
Failure by the Company to capture a significant number of the cellular network
operators as customers could have a material adverse effect on the Company's
business and operating results. See "Risk Factors--Limited Operating History;
Accumulated Deficit; Anticipated Losses," "--Significant Fluctuations in
Operating Results," "--Significant Customer Concentration" and "--Uncertainty
of Market Acceptance; Lengthy Sales Cycle."
 
RESULTS OF OPERATIONS
 
SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
  Net Revenue. Net revenue for the six months ended June 30, 1998 was $6.5
million, substantially all of which was derived from sales of the Motorola
HDII analog version of the Spotlight 2000 system to three customers. Net
Revenue for the six months ended June 30, 1997 was $392,000 all of which was
service revenue. International sales were 51.5% of net revenue for the six
months ended June 30, 1998. Although the Company anticipates that
international sales will continue to account for a significant portion of its
sales, the Company expects international sales to decrease as a percentage of
net revenue.
 
  Gross Profit (Loss). Cost of sales was $6.4 million and gross profit was
$105,000 for the six months ended June 30, 1998. Gross profit was adversely
affected by unabsorbed fixed manufacturing overhead costs due to the expansion
of manufacturing capacity in advance of unit sales volume increases.
Additionally, increases to the warranty and inventory obsolescence reserves
negatively impacted gross profit. Cost of sales was $516,000 and gross profit
(loss) was $(124,000) for the six months ended June 30, 1997. Cost of sales in
this period reflected the direct costs of the Network Services division
related supplies and expenses, and gross profit (loss) was adversely affected
by these relatively high fixed costs.
 
  Research and Development. For the six months ended June 30, 1998, research
and development expense was $8.0 million, of which $5.0 million was payroll
and benefits. For the six months ended June 30, 1997, research and development
expense was $5.4 million, of which $3.4 million was payroll and benefits. The
increase in research and development expense was primarily attributable to
increased staffing, prototype material costs and other associated expenses
relating to enhancing the features and functionality of the SpotLight 2000
system.
 
  Sales and Marketing. For the six months ended June 30, 1998, sales and
marketing expense was $4.1 million, of which $2.2 million was payroll and
benefits. For the six months ended June 30, 1997, sales and marketing expense
was $2.2 million, of which $1.4 million was payroll and benefits. The increase
in sales and marketing expense was primarily attributable to expansion of the
Company's direct sales force, as well as increased public relations and other
promotional expenditures.
 
  General and Administrative. For the six months ended June 30, 1998, general
and administrative expense was $2.4 million, of which $1.8 million was
payroll, $360,000 was in connection with certain patent license agreements and
$255,000 was stock compensation charges. For the six months ended June 30,
1997, general and administrative expense was $1.4 million, of which
$1.2 million was payroll and related expenses. The increase in general and
administrative expense was primarily attributable to increased personnel and
facility expenses necessary to support the Company's growth. The stock
compensation charge for the six months ended June 30, 1998 also contributed to
the increase over the prior year.
 
  Deferred Stock Compensation. In connection with the grant of certain stock
options during 1997, the Company recorded aggregate deferred stock
compensation of approximately $1.9 million,
 
                                      26
<PAGE>
 
representing the difference between the deemed value of the Common Stock for
accounting purposes and the option exercise price of such options at the date
of grant. Such amount is recorded as deferred stock compensation and amortized
ratably over the vesting period as stock compensation expense. For the six
months ended June 30, 1998, stock compensation expense was $328,000. For the
six months ended June 30, 1997, the Company recorded deferred stock
compensation of $224,000 and amortized a stock compensation expense of
$22,000. For the year ended December 31, 1997, the aggregate stock
compensation expense was $676,000.
 
  Interest Expense and Net Other Income. Interest expense increased to $2.2
million for the six months ended June 30, 1998, compared to $236,000 for the
six months ended June 30, 1997. The increase was primarily attributable to the
$2.0 million interest expense and associated fees to secure the $29.0 million
of 13.75% Senior Secured Bridge Notes. Net other income consists primarily of
earnings on the Company's cash and cash equivalents and short-term
investments. Net other income increased to $484,000 for the six months ended
June 30, 1998, from $409,000 for the six months ended June 30, 1997. The
increase was attributable to higher average cash and cash equivalent balances.
 
  Income Taxes. The Company has had a net loss for each period since
inception. As of June 30, 1998, the Company had approximately $39.3 million of
net operating loss carryforwards and $1.0 million of research and development
credit carryforward for federal income tax purposes, which begin to expire in
2009. The Company has provided a full valuation allowance on the deferred tax
asset, consisting primarily of net operating loss carryforward, because of
uncertainty regarding its realizability. See Note 7 of Notes to Financial
Statements.
 
YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995 (INCEPTION PERIOD)
 
  Net Revenue. Net revenue for 1997 and 1996 was $1.5 million and $1.3
million, respectively, and was attributable to services provided by the
Network Services division in 1997 and a one-time engineering consulting
contract in 1996. During 1995, the Company was primarily engaged in product
development and accordingly, recorded no revenue. The Network Services
division was discontinued in March 1998.
 
  Gross Profit (Loss). Cost of sales was $1.7 million and gross profit (loss)
was $(278,000) for the year ended December 31, 1997. Gross profit (loss) in
1997 was adversely affected by the high fixed cost of the Network Services
division during its initial year of operation. Cost of sales in this period
consists primarily of direct labor and materials related to services rendered
in generating the revenue for the period. Cost of sales was $1.1 million and
gross profit was $194,000 for the year ended December 31, 1996. Gross profit
in 1996 was attributable to a one-time engineering consulting contract.
 
  Research and Development. Research and development expense was $13.1
million, $7.2 million and $883,000 in 1997, 1996 and 1995, respectively. The
increases in research and development expense were primarily attributable to
increased staffing and associated costs related to product development. During
1997, research and development expense also included the design and
development of manufacturing infrastructure that was initially used for
prototyping activities.
 
  Sales and Marketing. Sales and marketing expense was $5.4 million, $1.7
million and $84,000 in 1997, 1996 and 1995, respectively. The increases in
sales and marketing expense were primarily attributable to expansion of the
Company's direct sales force and costs associated with initial field trials of
the SpotLight 2000 system.
 
  General and Administrative. General and administrative expense was $3.8
million, $2.4 million and $168,000 in 1997, 1996 and 1995, respectively. The
increases in general and administrative expense were primarily attributable to
increased payroll and related expenses in hiring additional personnel and
increased occupancy expenses necessary to support the Company's growth.
 
  Interest Expense and Net Other Income. Interest expense was $449,000,
$150,000 and $22,000 in 1997, 1996 and 1995, respectively. The increases in
interest expense were primarily attributable to increased capital lease
obligations and notes payable. Net other income was $851,000, $485,000 and
 
                                      27
<PAGE>
 
$157,000 in 1997, 1996 and 1995, respectively. The increases in net other
income were primarily attributable to interest income resulting from higher
cash and cash equivalent balances and short-term investments.

</TABLE>
 
  The Company's net revenue for the quarters in 1997 consisted primarily of
service revenue. Net revenue for the quarters ended March 31, 1998 and June
30, 1998 was primarily attributable to sales of the Company's SpotLight 2000
system.
 
  The significant fluctuations in the Company's historical quarterly operating
results are principally a function of the fact that the Company was a
development stage company through the latter part of the fourth quarter of
1997. These fluctuations are largely explained by significant increases and
large variations in expenses incurred in connection with the transition from
development stage to operating stage. Operating expense increased in each
quarter, primarily reflecting the increased expenditures related to the
Company's product development and its expanding workforce.
 
  The Company will likely experience significant fluctuations in its operating
results on a quarterly and an annual basis in the future. In connection with
its efforts to increase production of its recently introduced SpotLight 2000
system, the Company expects to continue to make substantial investments in
capital equipment, to recruit and train additional personnel and to invest in
facilities and management information systems. These expenditures may be made
in advance of, and in anticipation of, increased sales and, therefore, gross
profits may be adversely affected by short-term inefficiencies associated with
the addition of equipment, personnel or facilities and costs may increase as a
percentage of revenues from time to time on a periodic basis. As a result, the
Company's operating results will vary from period to
 
                                      28
<PAGE>
 
period. Because of the limited size of the Company's customer base and the
large size of customer orders, revenues derived from a small number of
customers will likely represent a significant portion of revenue in any given
period. Accordingly, a decrease in demand for the Company's systems from any
customer for any reason is likely to result in significant periodic
fluctuations in revenue. In addition, most of the Company's contracts contain
conditional acceptance provisions for certain product sales and the Company
delays recognition of revenues that are subject to such contingencies until
all such conditions are satisfied. If the Company could not satisfy conditions
in such contracts or satisfaction of conditions were delayed for any reason,
revenues in any particular period could fall significantly below the Company's
expectations. Many other factors may affect the Company's business and
operating results in future periods. See "Risk Factors--Limited Operating
History; Accumulated Deficit; Anticipated Losses" and "--Significant
Fluctuations in Operating Results."
 
YEAR 2000 COMPLIANCE
 
 
  Many currently installed computer systems and software products are coded to
accept only two-digit entries in the date code field. 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. As a result, in less
than two years, computer systems and software used by many companies may need
to be upgraded to comply with such year 2000 requirements. In 1998 the Company
installed an enterprise resource planning system that the vendor warrants is
year 2000 compliant. The Company's current estimate is that the costs
associated with the year 2000 issue, and the consequences of incomplete or
untimely resolution of the year 2000 issue, will not have a material adverse
effect on the result of operations or financial position of the Company in any
given year. However, despite the Company's efforts to address the year 2000
impact on its internal systems, the Company has not fully identified such
impact or whether it can resolve it without disruption of its business and
without incurring significant expense. In addition, even if the internal
systems of the Company are not materially affected by the year 2000 issue, the
Company could be affected through disruption in the operation of the
enterprises with which the Company interacts. See "Risk Factors--Year 2000
Compliance."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed its operations primarily through
private sales of Preferred Stock and Common Stock, the issuance of debt
instruments, capital leases arrangements and borrowings under various lines of
credit. Net proceeds from these transactions totaled $85.8 million as of June
30, 1998.
 
  For the six months ended June 30, 1998, net cash used in operating
activities was $20.8 million resulting from a net loss of $16.2 million and
increases of $8.1 million in inventories offset by decreases of $4.9 million
in accounts payable, accrued liabilities and other liabilities. Net cash used
in operating activities was $23.6 million, $10.2 million and $309,000 in 1997,
1996 and 1995, respectively. For 1997, cash used in operating activities
resulted from a net loss of $22.1 million and increases of $4.1 million in
inventories, $1.3 million in accounts receivable and $34,000 in prepaid
expenses and deposits partially offset by increases of $926,000 in accounts
payable, accrued liabilities and other liabilities and $1.8 million in
depreciation and amortization. For 1996, cash used in operating activities
resulted from a net loss of $10.8 million and increases of $67,000 in accounts
receivable and $222,000 in prepaid expenses partially offset by increases of
$906,000 in accounts payable, accrued liabilities and other liabilities and
$520,000 in depreciation and amortization. Cash used in operating activities
in 1995 was attributable to a net loss of $1.0 million and an increase of
$55,000 in prepaid expenses partially offset by an increases of $206,000 in
accounts payable, accrued liabilities and other liabilities and $19,000 in
depreciation and amortization.
 
  Net cash provided by (used in) investing activities of $(504,000),
$(621,000), $3.1 million and $(3.8 million) for the six months ended June 30,
1998 and the years ended December 31, 1997, 1996 and 1995, respectively, was
primarily related to purchases of property and equipment and purchases of
short term investments offset by maturities of short term investments. The
large increases in working capital on a period-to-period basis are a direct
result of the rapid growth of the Company in support of the product
development and sales and marketing efforts as well as the development of an
operational infrastructure to
 
                                      29
<PAGE>
 
support the sales of product in the recent quarters. Such growth has required
the Company to purchase additional equipment and software and increase purchase
of materials, which resulted in corresponding increases in inventories and
accounts payable.
 
  Cash provided by (used in) financing activities of $28.2 million for the six
months ended June 30, 1998 consisted of $29.0 million in proceeds from issuance
of 13.75% Senior Secured Bridge Notes offset by $130,000 in payments on debt
securities and $717,000 in principal payments on capital lease obligations.
Cash provided by financing activities of $18.4 million in 1997 consisted
primarily of $19.2 million in net proceeds from the issuance of Series D
Preferred Stock. Cash provided by financing activities of $24.8 million in 1996
was primarily from net proceeds of $24.6 million from the issuance of Series B
and C Preferred Stock and $500,000 of proceeds from the issuance of a note
payable. Cash provided by financing activities of $5.5 million in 1995
consisted primarily of $5.5 million in net proceeds from the issuance of Series
A Preferred Stock.
 
  In April 1998, the Company issued $29.0 million in aggregate principal 13.75%
Senior Secured Bridge Notes due April 28, 2000 to certain institutional and
corporate investors. The 13.75% Senior Secured Bridge Notes are secured by the
Company's personal property and intellectual property. The Company is required
to comply with certain covenants and certain reporting requirements determined
by the noteholders. On April 28, 1999 and each 180-day period thereafter until
the 13.75% Senior Secured Bridge Notes are repaid in full, the interest rate
will increase by 200 basis points up to a maximum of 18.0%. In addition, the
Company issued the Note Warrant to purchase an aggregate of 537,500 shares of
Series D Preferred Stock at a purchase price of $0.01 per share. The Note
Warrants expire on April 28, 2000. Pursuant to the terms of the 13.75% Senior
Secured Bridge Notes, upon the closing of this offering, the Company is
obligated to repay one-half of the aggregate principal amount of the 13.75%
Senior Secured Bridge Notes outstanding, together with accrued but unpaid
interest thereon. The remaining outstanding 13.75% Senior Secured Bridge Notes
are redeemable at the Company's option at any time prior to the maturity date.
Upon the closing of this offering, the Company has the right to redeem all of
the 13.75% Senior Secured Bridge Notes, Note Warrants and to repurchase any
stock issued upon exercise of the Note Warrants for an aggregate redemption
price of $40.6 million.
 
  The Company has a credit facility with a commercial bank, which provides for
a revolving credit line of $7.5 million to support working capital with a $3.0
million sublimit for issuance of trade-related commercial and standby letters
of credit, which matures on October 14, 1999. Outstanding balances on the
credit line bear interest at the bank's prime rate and are secured by the
Company's accounts receivable and inventory. As of the date hereof, no amounts
were outstanding under this revolving credit line secured by accounts
receivable and $2.5 million is outstanding related to issuance of a standby
letter of credit. See Note 4 of Notes to Financial Statements.
 
  The Company has several capital leases with terms ranging from 36 to 48
months. At June 30, 1998, the Company's outstanding capital lease obligations
were $5.1 million, accruing interest at rates ranging from 7.25% to 14.50%. On
April 17, 1998, the Company entered into an additional $3,500,000 capital lease
line with a 36 month term. See Note 8 of Notes to Financial Statements.
 
  As of June 30, 1998, the Company had $20.3 million of cash and cash
equivalents. As of June 30, 1998, the Company's principal commitments consisted
of accounts payable, current debt payable, convertible and redeemable preferred
stock and obligations outstanding under operating and capital leases. Although
the Company has no material commitments for capital expenditures, management
anticipates a substantial increase in its capital expenditures and lease
commitments consistent with anticipated growth in operations, infrastructure
and personnel. The Company may establish additional field service and customer
support locations, which would require it to commit to additional lease
obligations. In the future, the Company may support larger inventories in order
to provide shorter lead times to customers and achieve purchasing efficiencies.
 
                                       30
<PAGE>
 
  The Company will use approximately $16.2 million of the net proceeds
received from this offering to repay one-half of the outstanding principal and
estimated accrued interest on the 13.75% Senior Secured Bridge Notes and the
remaining proceeds of $31.8 million will be used for general corporate
purposes, including working capital to fund anticipated operating losses and
capital expenditures. See "Use of Proceeds." Following the expected
application of the estimated net proceeds of this offering together with
repayments of debt prior to this offering the Company will have $14.5 million
in outstanding principal 13.75% Senior Secured Bridge Notes.
 
  The Company believes that the net proceeds from this offering, together with
its cash and cash equivalents, will be sufficient to meet its capital
requirements for at least twelve months. The Company's future capital
requirements will depend upon many factors, including the success or failure
of the Company's efforts to expand its production, sales and marketing
efforts, the status of competitive products and the requirements of the
Company's efforts to develop new products and product enhancements. To the
extent that the funds generated by this offering, together with existing
resources and future earnings, are insufficient to fund the Company's future
activities, the Company may need to raise additional funds through public or
private financing. There can be no assurance that additional financing will be
available to the Company on acceptable terms, or at all, or that such
financing would not result in further dilution to existing stockholders. See
"Use of Proceeds."

trial with GTE.
 
INDUSTRY BACKGROUND
 
  The worldwide demand for wireless communications services has grown
significantly in recent years, largely as a result of technological
advancements and economies of scale that have substantially reduced the cost
and improved the quality and reliability of wireless services for the business
and consumer mass market. In addition, worldwide deregulation of the wireless
communications industry and increased government allocation of spectrum have
resulted in wider availability of wireless radio frequency and increased
competition among existing and new wireless network operators, further reducing
cost to the end user and stimulating demand. According to Dataquest, the number
of cellular and PCS subscribers increased 45% in 1997, from 134 million to 194
million, and is projected to be approximately 550 million by 2001.
 
  The demand for wireless communications services is expected to continue to
grow rapidly, as communications technology is driving the evolution of the
digital information age. The convergence of data communications, telephony and
wireless communications is straining public and private networks worldwide and
requiring the development of new technologies in order to enable the rate of
change to continue. Devices with wireless access such as mobile phones and palm
computers and the combination of wireless and internet protocol-based LAN
infrastructure may enable mobile customers to access services such as web
initiated telephony, unified messaging and advanced conferencing.
 
  The need for mobile communications ubiquity places a significant strain on
wireless service providers given the fixed amount of radio frequency spectrum
or wireless bandwidth available to deliver wireless services. Unlike
traditional data and telephony communications bandwidth, which is a physical
medium, wireless spectrum is an invisible medium and is generally allocated in
fixed amounts by governments in U.S. and foreign markets. Traditional methods
used in data and telephony networks for increasing available bandwidth through
the adoption of new technologies, such as frame or cell based switching or
dense wave division multiplexing, generally do not apply in wireless networks.
Thus, the fundamental challenge for wireless network operators is to increase
capacity, coverage and call quality within a fixed amount of wireless spectrum.
 
                                       32
<PAGE>
 
  To address capacity, coverage and call quality issues, wireless operators
have begun to deploy more spectrum-efficient digital technologies such as CDMA,
GSM and TDMA since the late 1980s. However, because analog and digital cellular
networks share the same fixed amount of spectrum, cellular network operators
must remove analog channels to implement digital technology. To install one
CDMA carrier into a network, an operator must clear 15 percent of its existing
analog spectrum. Removal of analog spectrum creates additional capacity
constraints within an existing analog network that is already nearing capacity
limits from the growing demand for analog minutes of use. As digital traffic
grows within analog systems, additional digital carriers must be added,
requiring more analog channels to be cleared. According to the Cahners In-Stat
Group, clearing analog spectrum to accommodate digital growth is expected to
continue for the next five to seven years as demand for digital capacity
increases.
 
  The need to provide analog cellular service to increasing numbers of
subscribers while simultaneously clearing fixed spectrum for digital deployment
creates numerous challenges for cellular network operators. Traditionally,
operators of 800 MHz cellular networks addressed capacity, coverage and call
quality problems by building new cell sites. According to the Cellular
Telecommunication Industry Association ("CTIA"), wireless network operators
added approximately 21,000 new cell sites worldwide in 1997. However,
constructing a new site, including land, building and equipment, can cost up to
$1,000,000, and technical factors such as frequency reuse limitations diminish
the marginal benefits of adding cell sites to networks. For example, building
cell sites closer together increases interference and noise in the network,
which reduces capacity and call quality, exacerbating the very problems the
additional cell sites are intended to resolve. Cellular network operators also
face significant community resistance arising from environmental concerns and
aesthetic objections to the appearance of cell site towers.
 
  In addition to building more cell sites, cellular network operators have
adopted variations on antenna design. Traditionally, operators used omni-
directional (360(degrees)) antennas, which receive and transmit in all
directions around a cell site. This has the advantage of making all radio
channels available to any cellular caller, but has the disadvantage of being
susceptible to interference from all directions. In areas where interference is
a problem, cellular network operators have often installed sectorized antennas,
usually consisting of a suite of three antennas, each covering a different
120(degrees) sector around a cell site. While sectorized antennas reject
signals from outside their sector, decreasing the overall level of interference
within a cell site, they can also reduce cell site capacity because each radio
channel is permanently allocated to a specific sector, and therefore cannot be
reused to cover other sectors.
 
  The growing demand for wireless services and the difficulties encountered by
cellular network operators in building additional cell sites and implementing
digital technologies contribute to the need for a cost-effective solution to
capacity, coverage and call quality problems. Cellular network operators need
solutions that work within the framework of intense wireless service
competition and reduced capital budgets. As they seek to provide ubiquitous
wireless service and support increased subscriber demand, cellular network
operators must address the fundamental challenge of achieving maximum capacity
from finite spectrum resources. Metawave believes that the growing demand for
wireless services as well as the set of technological problems and economic
constraints imposed by finite spectrum resources presents an attractive market
opportunity for providers of spectrum management solutions.
 
THE METAWAVE SOLUTION
 
  Metawave's spectrum management solutions, consisting of smart antenna
systems, applications software and engineering services, enable cellular
network operators to increase overall network capacity, reduce network
operation costs, better manage network infrastructure and stimulate end user
demand through improved system quality. The Company's initial spectrum
management platform, the SpotLight 2000 system, is a multibeam smart antenna
technology that is compatible with the Motorola HDII and Lucent Series II base
stations and AMPS and CDMA air interface protocols. The SpotLight 2000 system
divides the cell site coverage pattern into 12 fixed beams and incorporates
electronics and software to
 
                                       33
<PAGE>
 
create the optimum signal for each radio in the cell site. The Company's
spectrum management solutions provide cellular network operators with the
following benefits:
 
  Cost-Effective Capacity Expansion. The SpotLight 2000 system enables cellular
network operators to increase the capacity of their networks without the
increased network complexity and expenses associated with new cell site
development. The SpotLight 2000 system integrates narrow-beam antennas with RF
signal-processing hardware and beam-switching algorithms to provide stronger
signal reception and reduced interference. This enables cellular network
operators to more efficiently allocate radio frequencies and thereby increase
network capacity. The SpotLight 2000 system can be installed in a single cell
site or in multiple sites in a network. The system can be used to increase
analog capacity only or can be deployed in a dual-mode configuration to
simultaneously increase both analog and CDMA capacity. Based on field trials,
the Company estimates that the SpotLight 2000 system, when installed in a
network of cell sites, can improve analog capacity by as much as 100% and, when
used in a dual-mode system, can improve CDMA capacity by up to 40%.
 
  Efficient Conversion to Digital Network Capability. The SpotLight 2000 system
enables cellular network operators to use existing cell site infrastructure to
support current traffic levels with less of their allocated spectrum and fewer
channels. As a result, the SpotLight 2000 system facilitates the transition
from frequency-intensive analog service to more spectrum-efficient digital
service. Operators can use the SpotLight 2000 system to clear spectrum for the
first and each subsequent CDMA carrier while maintaining analog capacity and
service quality.
 
  Improved Network Performance. By providing a stronger signal and by reducing
interference, the SpotLight 2000 system can improve coverage in certain
portions of a cell site's geographic footprint, such as the interior of
buildings, where coverage is often insufficient. This stronger signal and
reduced interference can improve network quality. In addition, the SpotLight
2000 system provides RF engineers with the ability to measure and report
performance statistics in 30(degrees) increments around the cell site. Using
this data, engineers can better isolate specific network performance metrics
and determine optimum sector configurations.
 
STRATEGY
 
  The Company's objective is to be a leading provider of spectrum management
solutions to the worldwide wireless communications market. The Company's
strategy to achieve this objective incorporates the following key elements:
 
  Provide Solutions to High-Growth Wireless Communications Markets. The Company
seeks to identify rapidly growing wireless markets and to develop highly
integrated solutions to spectrum management problems in those markets. The
Company designed the SpotLight 2000 system initially for use in AMPS cellular
networks. In order to address the capacity and system quality problems facing
AMPS operators implementing CDMA digital technologies, the Company has
leveraged the SpotLight 2000 system technology to develop a dual-mode solution
that incorporates CDMA and AMPS protocols. The Company intends to explore other
high-growth markets such as GSM, PCS, TDMA and WLL and, if appropriate, to
develop similar solutions for such markets.
 
  Build and Expand Strategic Customer Relationships. Metawave is dedicated to
serving those cellular network operators which the Company believes are most
likely to adopt and promote the Company's solution across their networks. The
Company uses a direct sales model and has established significant field
engineering expertise that enables the Company to install and optimize its
equipment within customers' cell sites. The Company's system engineers work
closely with the Company's direct sales personnel and customers to ensure that
the Company's product performance is optimized for each operator's network. In
addition, the Company has developed expertise in assisting cellular network
operators in planning and improving overall network performance.
 
                                       34
<PAGE>
 
  Leverage Proprietary Core Technology. The Company seeks to continue to build
its core technology, which includes eight issued and 25 pending patents, and to
invest substantial resources in technology research and product development.
The Company has leveraged its core technology and expanded its customer base by
modifying its SpotLight 2000 system for use with the Lucent Series II base
station in addition to the Motorola HDII base station for which it was
initially developed. The Company is currently modifying the SpotLight 2000
system to interface with equipment made by other manufacturers, such as the
Ericsson 882 and Motorola SC2450 and SC9600 base stations, and intends to
expand into new technology markets by developing spectrum management solutions
for the GSM, PCS, TDMA and WLL markets, as appropriate. To facilitate the
adoption and deployment of the Company's spectrum management solutions, the
Company intends to develop stand-alone products and applications that are
readily installed in existing or new cell sites. The Company may establish
strategic relationships both to develop new technologies and to expand into new
markets.
 
  Focus on Highly Integrated System Solutions. The Company seeks to offer
system level products that enhance the performance of cellular network
operators' base station equipment. The Company will provide highly integrated
solutions that include pre-sales system planning, products configurable to
specific base station requirements and on-site installation and optimization
services to ensure a high level of system performance. The Company's highly
integrated system approach differentiates it from the component level product
offerings currently available in the market.
 
MARKETS
 
  Today's wireless communications industry is characterized by several
protocols that divide the industry into broad markets. Currently, networks
based on the AMPS and GSM protocols have the greatest number of subscribers
and, correspondingly, the largest number of cell sites. The Company expects
digital technologies to grow rapidly and account for increased levels of
infrastructure spending. Many analog cellular network operators are migrating
their analog networks to digital to increase capacity and improve their
competitive position relative to emerging PCS providers. Regardless of the
protocol adopted or the frequency band used, the Company believes wireless
network operators worldwide will need to address capacity, coverage or call
quality issues.
 
  Analog Cellular Market. The analog cellular market consists of operators that
provide cellular service within the 800 MHz and 900 MHz frequency bands using
analog technology. The predominant analog protocol is AMPS, which according to
the Strategis Group serves 71.0% of total analog subscribers worldwide. In
areas of the world where digital technology has not yet been introduced, AMPS
networks are growing to serve continued subscriber demand. In areas where
deployment of digital service is underway or planned, maintaining analog
capacity, coverage and call quality during this transition is essential. In
addition to currently serving the majority of subscribers and minutes of use in
North America, AMPS technology will also serve digital customers in cases where
they roam to other networks, in areas where digital service is not yet in place
and in circumstances where digital capacity is not sufficient to carry the
level of traffic. AMPS cellular phones also remain significantly less expensive
than digital and dual-mode phones. For these reasons, the Company believes the
migration to digital service will be an extended process. Moreover, the Company
believes that cellular network operators may be reluctant to allow AMPS service
quality to deteriorate during this process due to the presence of significant
competition from other cellular and emerging PCS operators. The Company's
SpotLight 2000 system enables cellular network operators to provide enhanced
capacity, coverage and call quality to facilitate this transition to digital
service.
 
  CDMA Digital Cellular Market. The CDMA digital cellular market consists of
operators overlaying CDMA technology onto existing AMPS technology in the 800
MHz frequency band. To deploy a single CDMA carrier, cellular network operators
must clear a portion of spectrum (approximately 15% in North and South America)
that was previously utilized for AMPS service. This involves taking analog
channels off the air, exacerbating capacity shortages and deteriorating network
quality. Approximately half of the
 
                                       35
<PAGE>
 
cellular networks in North America are ultimately expected to migrate to CDMA
technology as are many cellular network operators in South America. Cellular
network operators must separately optimize the CDMA portion of their network in
order to achieve the necessary capacity and performance. The Company's
SpotLight 2000 system provides additional analog capacity facilitating spectrum
clearing without adversely affecting capacity or network quality. The SpotLight
2000 system also provides additional CDMA capacity to manage the transition
from analog-only networks to dual-mode networks.
 
  GSM Market. The GSM market consists of networks that operate at 900 MHz and
1800 MHz. GSM was the first widely implemented digital technology and is
deployed in 110 countries, predominantly in Europe and Asia. As the most widely
deployed digital technology, GSM served 48.5 million subscribers at the end of
1997, according to the Strategis Group, and Allied Business Intelligence
estimates that GSM will account for over 50% of worldwide wireless subscribers
by 2000. GSM is not as spectrally efficient as other digital technologies.
Consequently, GSM networks are beginning to experience capacity constraints,
particularly in heavily subscribed areas. The Company believes that these
capacity shortfalls will become more common. The Company is currently
developing a product to provide cost-effective spectrum management solutions
for GSM network operators.
 
  TDMA Market. The TDMA digital cellular market consists of operators
overlaying TDMA technology onto existing AMPS technology in the 800 MHz
frequency band. The TDMA market represented approximately 50% of the North
American digital cellular market, as well as a significant portion of the South
American market at the end of 1997, according to the Strategis Group. TDMA
operates on analog channels, and therefore can reduce analog capacity. As
subscriber growth continues on these networks, the capacity gains of TDMA may
not be sufficient to accommodate subscriber growth. Although the Company
currently has no TDMA solution under development, the Company believes that its
technology is applicable to the issues facing TDMA operators. The Company
continues to evaluate the economic viability of a TDMA solution and may in the
future undertake product development for TDMA.
 
  PCS Market. In 1995 and 1996, the U.S. government auctioned new licenses at
frequencies of 1900 MHz, known as PCS. These licenses represent 120 MHz of new
spectrum compared to 50 MHz of spectrum held by the existing cellular network
operators. In doing so, the government opened up each wireless market to new
competitors. These new PCS operators represent a significant competitive threat
to cellular network operators. Since entering the market in 1997, deployed PCS
networks currently provide coverage to geographic regions covering
approximately 75% of the U.S. population and, according to The Yankee Group,
PCS accounted for 20% of all new wireless accounts in the United States in
1997. PCS operators deploy digital networks, using CDMA, TDMA or GSM
technology, which offer enhanced services, better security and more capacity
than analog networks. In addition, customer churn has intensified as a result
of new consumer choices. As these networks grow, it is expected that they will
experience capacity and optimization issues similar to cellular networks. The
Company continues to evaluate potential spectrum management solutions for PCS.

METAWAVE PRODUCTS
 
  The Company has developed spectrum management solutions, consisting of smart
antenna systems, applications software and engineering services, that enable
cellular network operators to increase overall network capacity, reduce network
operation costs, better manage network infrastructure and stimulate end user
demand through improved system quality. The Company's initial spectrum
management platform, the SpotLight 2000 system, is a multibeam smart antenna
technology that interfaces with Motorola HDII and Lucent Series II base
stations and is compatible with AMPS and CDMA air interface protocols.
 
  Metawave's proprietary spectrum management solutions enable the transition
from traditional wireless network infrastructure designs to an architecture
which actively optimizes finite spectrum or wireless bandwidth, thereby
enhancing the performance and increasing overall network capacity of the
cellular

operator's network. The architecture, shown in the figure below, adds smart
antenna performance to the cellular operator's network.
 
                            [GRAPHIC APPEARS HERE]
 
  SpotLight Platform. The Company's SpotLight 2000 smart antenna system was
initially designed for use in AMPS networks and was first shipped for
commercial sale in November 1997. The second generation SpotLight 2000 system
was designed as a dual-mode system and is currently in field trials. The
SpotLight 2000 system divides cell site antennas into 12 beams and incorporates
electronics and software to optimize the signal for each radio in the cell
site, resulting in increased network capacity and improved call quality.
Designed for 800 MHz networks, the SpotLight 2000 system currently provides
solutions for AMPS networks or dual-mode AMPS and CDMA networks.
 
  Based on field trials, the Company estimates that the SpotLight 2000 system,
when installed in a network of cell sites, can improve analog capacity by as
much as 100% and, when used in a dual-mode system, can improve CDMA capacity by
up to 40% without increasing the number of cell sites. Accordingly, the
SpotLight 2000 system is a cost-effective tool for clearing spectrum of analog
use to accommodate the transition of networks to digital service. Capacity is
increased by allowing for tighter re-use of frequency or by obtaining increased
trunking efficiency or a combination of both.
 
  The Spotlight 2000 system interfaces with base stations by coupling directly
to the I/O ports of base station radios and by processing transmit and receive
signals through its smart antenna spectrum management system. The Company
provides all necessary hardware and software to process transmit and receive
signals, including Spectrum Management Units ("SMUs"), linear power amplifiers,
filters and other equipment, including base station antennas.

  As the SpotLight 2000 system reduces interference in a network through
implementation of smart antennas, more channels can be added to each cell site
because frequencies can be reused more times over a given area, thereby
increasing network capacity. In areas where interference is a problem, cellular
network operators have often installed sectorized antennas, usually consisting
of a suite of three antennas, each covering a 120(degrees) sector around a cell
site. Sectorization reduces the amount of interference received by a given cell
site radio. The SpotLight 2000 system's 12 beam smart antenna has four times
the interference rejection potential of a three-sector antenna. As shown in the
figure below, the 12 beam antenna rejects potential signal interference that is
outside the caller's narrow 30(degrees) beam, reducing network interference.
This enables a cellular network operator to reuse the same frequencies more
often over a given service area, thereby adding more channels to each cell
site.

                            [GRAPHIC APPEARS HERE]
 
  Trunking efficiency represents a statistical measure of the call carrying
capacity of a set of channels. Trunking efficiency is increased whenever a
greater number of channels is made available for use by a group of subscribers
at a given location and time. Conventional three-sector antennas tend to reduce
capacity because they restrict the callers in any given sector to the cell site
radio channels assigned to that sector. In contrast, the SpotLight 2000
system's SMU's permit any caller in any beam to be assigned to any cell site
radio, thereby increasing the trunking efficiency and the cell site's capacity.
The primary interface between the SpotLight 2000 system and the cell site is
the set of RF connections between the transmit and receive terminals on cell
site radios and the SpotLight 2000 system's SMUs, which contain the core of
SpotLight's smart antenna capability. While any call is active, the SMUs
continuously measure call quality and make adjustments in beam assignment to
maintain the best possible call quality.
 
  Through the SpotLight 2000 system, cellular network operators deploying dual-
mode smart antenna systems can use a single set of antennas for both their
analog and CDMA networks, and can optimize each network's performance
independently.
 
  The SpotLight 2000 system also increases CDMA capacity because it allows
operators to manage and distribute traffic loading more effectively. The
geographic distribution of traffic loading across a CDMA network or within a
single cell varies considerably. In a typical three-sector cell, the traffic
density in the most heavily loaded sector is often significantly higher than
the least-loaded sector. As a result, some cells may have sectors that are
fully loaded with cellular traffic while other sectors of the same cell are
well below peak loading and have spare capacity. On a network scale, high
cellular traffic areas, such as highway interchanges, urban centers and
shopping centers, can become "hot spots" that strain network capacity even as
network resources go unused in low cellular traffic areas. This variability in
traffic density creates network inefficiencies and lower network capacity,
particularly in CDMA networks.
 
  To address traffic loading, the SpotLight 2000 system controls the
transmission and reception of CDMA radio signals by base stations through a
process called sector synthesis. The SpotLight 2000 system
 
                                       39
<PAGE>
 
adapts the sector coverage of the base stations' CDMA radios to the local
traffic patterns around cell sites. The system's phased-array antenna makes it
possible to create custom sector antenna patterns of varying degrees though an
embedded software-driven process. Optimization of the SpotLight 2000 system for
CDMA requires information about the CDMA signals on the network, which the CDMA
equipment within the system gathers through the antennas. Sector synthesis
occurs through software algorithms, which can be modified remotely to respond
to changing local traffic patterns in real time. Through sector synthesis,
cellular network operators also optimize their CDMA networks with increased
flexibility and precision, enhancing network capacity and performance in
response to changing traffic patterns as well as local terrain and variable RF
conditions, as illustrated in the following diagram.

  Other Spectrum Management Products. The SpotLight 2000 system can be
administered and monitored locally or remotely through LampLighter, SpotLight
2000's system configuration product. LampLighter, a Windows-based software
tool, configures the SpotLight 2000 system for optimal cell site performance.
In addition, LampLighter allows real time monitoring of system performance
through graphical displays and log files.
 
  In addition to the configuration capabilities of LampLighter, the Company
offers networked access to the SpotLight 2000 system configuration with its
SiteNet software product. SiteNet also provides a means for centralized
collection and analysis of RF performance statistics in analog and CDMA
networks. Cellular network operators can use the networked configuration
capability, as well as networked RF performance statistics, to attain remote
control of antenna operations across a network of SpotLight 2000 systems.
 
CORE TECHNOLOGY
 
  The Company believes that one of its key competitive advantages is its
investment and expertise in the core technologies that enable efficient
spectrum management of wireless communications networks. Spectrum management
encompasses a number of technical components, including advanced antenna
concepts, radiowave propagation models, network performance monitoring tools,
common air interface knowledge and communications systems hardware
implementations. These core competencies, when applied in combination, allow
cellular network operators to optimize capacity, coverage and quality across
their networks. The Company has developed, and continues to expand upon, the
following four fundamental technical elements:
 
  Phased-Array Antenna Systems. The Company has developed phased-array antenna
systems that provide compact beam-forming within a single structure. The
antenna systems make use of uniform linear
 
                                       40
<PAGE>
 
or cylindrical arrays with a combination of both ground-based and tower-based
feed networks. The Company has designed antennas to synthesize multiple narrow
fixed-beams, which can be used to track individual users within a cell site.
In addition, the Company has developed beam-forming techniques to allow the
coverage area of a cell site to be customized. The phased-array antenna
technology can be scaled to a variety of gains and to span a broad range of
frequencies. The basic implementations are protocol independent, and as such
can be applied to analog, TDMA and CDMA and other wireless networks. The
phased-array technology is extendible to as many as 128 simultaneous narrow
fixed-beams for high density applications or high bit rate services. Phased-
array antenna technology has potential applications in ground-based mobile
radio (cellular, PCS, enhanced specialized mobile radio ("SMR")), two-way
paging, local multipoint distribution service ("LMDS") as well as in emerging
satellite-based wireless services.
 
  Multibeam Hardware Architectures. The Company has developed cost-effective
hardware implementations of the complex circuitry necessary to support the
operation of multibeam systems on high-traffic cell sites. The hardware
architecture can be organized into several key subsystems: beam switching
matrices, ultra-linear amplification, beam-forming feed structures, array
calibration circuitry and performance measuring receivers. The Company has
designed compact high-density RF switch matrices for use in fast beam-
switching applications. The Company's beam-switching technology is modular,
reliable and readily adaptable to both TDMA and analog protocols, where rapid
beam switching is required. The Company holds proprietary technology for the
implementation of modular, scalable architectures that support beam-switching
and beam-forming. The Company has developed proprietary hardware techniques
for feeding and calibrating phased-arrays integrated into existing cell site
configurations. To monitor the radio environment, the Company has developed
high-speed, frequency-agile scanning receivers designed to accurately operate
over various channel bandwidths. The Company's controlled impedance circuit
board designs implement low-loss routing of hundreds of microwave signal paths
while maintaining low voltage standing wave ratio ("VSWR") and minimal
crosstalk. Additionally, the Company has patents related to architectures to
implement beam-switching for the CDMA protocol. The Company's spatial
technology allows the simultaneous operation of multiple protocols (for
example AMPS/CDMA or AMPS/TDMA) through the same physical antenna structure,
while maintaining independent optimization of the performance for each
protocol.
 
  Real-Time Network Control Algorithms. The Company has developed algorithms
to control beam switching hardware based upon extensive drive testing, data
gathering, statistical analysis and propagation modeling in complex, real-
world radio environments. These algorithms make real-time decisions about
which beams best serve each user, how often to update beam selections and how
to mitigate interference from other users on the same or adjacent channels.
The Company has patents related to cellular beam spectrum management and
forward-looking interference cancellation technology. In addition, the Company
has developed expertise in the optimization of cellular network performance
for AMPS/NAMPS and CDMA protocols. Such expertise allows network control
algorithms to be customized based on the specific protocol and network
deployment scenario. The Company has also developed internal software tools
for performance modeling cellular networks. These proprietary tools allow
evaluation of new algorithms for spectrum management on mixed analog and
digital cellular networks.
 
  Adaptive Beam-Forming Techniques. The Company designs and builds antenna
systems with a broad range of standard and custom beam types and shapes using
adaptive beam-forming technology. With respect to CDMA, the Company's system
makes use of the phased-array antenna to create custom sector antenna patterns
though an embedded software-driven process known as sector synthesis. Under
software control, independent selection of sector azimuth pointing angles,
beamwidths and per-beam gains can provide flexibility to fine-tune network
performance. With sector synthesis, cellular network operators can create
completely different sector mappings for AMPS and CDMA, thus allowing
independent network optimization while sharing the cell site's equipment,
including antennas. Adaptive beam-forming systems can monitor traffic loading
and interference levels and then respond by implementing changes designed to
equalize traffic loads and reduce interference.

CUSTOMERS
 
  Metawave works closely with its customers to establish long-term
relationships and to provide opportunities to expand the delivery of its
spectrum management solutions to these customers. Since 1996, the Company has
conducted field trials with a number of cellular network operators to test its
technology and to demonstrate the SpotLight 2000 system's capability to these
customers. These trials are an essential element in the Company's sales cycle.
Late in the fourth quarter of 1997, the Company began commercial shipment of
the Motorola HD-II analog-only version of its SpotLight 2000 system. In early
1998, the Company began field trials to demonstrate the capability of its
SpotLight 2000 Lucent Series II system for both analog and CDMA.
 
  The following table sets forth a list of companies that have purchased or
are evaluating the purchase of the SpotLight 2000 system as of June 30, 1998.

(1) On July 1, 1998, ALLTEL completed the acquisition of 360(degrees)
    Communications.
 
(2) These sales are conditional upon the achievement of certain performance
    criteria set forth in the sales contracts. No revenue is recognized by the
    Company until all customer acceptance conditions have been met.
 
  There can be no assurance that successful completion of a given field trial
will result in a system sale. The sale of the Company's products is subject to
numerous risks and uncertainties. In order for its products to achieve market
acceptance, the Company must demonstrate to cellular network operators that
the products provide a spectrum management solution that addresses the
cellular network operators' challenges of capacity, coverage and call quality
in a cost-effective manner. The Company must demonstrate product performance
to a cellular network operator based on such operator's needs and
specifications and the difficulty in optimizing the Company's product in any
given cell site varies greatly depending on such operator's specifications and
the geographical terrain. Typically, performance of the Company's product must
be accepted in an initial cell site or cluster of cell sites prior to
completing any additional sales to such cellular network operator. If the
Company's products are not accepted by cellular network operators in a timely
manner, or at all, the Company's business and operating results will be
materially adversely affected. See "Risk Factors--Uncertainty of Market
Acceptance; Lengthy Sales Cycle," "--Dependence on Cellular Network Operator
Capital Spending" and "--Competition."
 
  During the six months ended June 30, 1998, sales to St. Petersburg Telecom,
Telefonica Celular and ALLTEL accounted for 95.7% of net revenue. Sales to
these three customers are expected to continue to account for a substantial
majority of sales through the remainder of fiscal 1998. The loss of any of
these customers, or a significant loss, reduction or rescheduling of orders
from any of these customers, could have a material adverse effect on the
Company's business and operating results. See "Risk Factors--Significant
Customer Concentration" and "--Dependence on Growth of Cellular Communications
Market."

SALES, MARKETING AND CUSTOMER SUPPORT
 
  Metawave sells its products through a technical direct sales force supported
by systems engineers. Direct sales personnel are assigned on a customer
account basis and are responsible for generating product sales, providing
product and customer support and soliciting customer feedback for product
development. In addition, sales personnel receive support from the Company's
marketing organization.
 
  The Company's marketing efforts are primarily focused on establishing and
developing long-term relationships with potential customers. As is customary
in the industry, sales are made through standard purchase orders which can be
subject to cancellation, postponement or other types of delays. While certain
customers provide the Company with forecasted needs, they are not bound by
such forecasts. Historically, the Company has conducted field trials and has
been required to satisfy performance conditions prior to the completion of a
sale. For these and other reasons, the sales process associated with the
purchase of the Company's systems is typically complex, lengthy (up to 18
months or more) and subject to a number of significant risks, including
changes in customers' budgets and approval at senior levels of customers'
organizations and approval by governmental agencies. See "Risk Factors--
Uncertainty of Market Acceptance; Lengthy Sales Cycle."
 
  International sales of the Company's products accounted for 51.5% for the
six-month period ended June 30, 1998. There were no international sales for
the years ended December 31, 1995, 1996 and 1997. Foreign sales of the Company
products may be subject to national security and export regulations and may
require the Company to obtain a permit or license. See "Risk Factors--
Government Regulation." The Company has not experienced any material
difficulty in obtaining required permits or licenses. Installation and
operation of the Company's products may also require approval from
governmental agencies in these countries. Foreign sales are also subject to
risks related to political instability and economic downturns in foreign
nations. The Company's foreign customers typically pay for the Company's
products with U.S. dollars. As such, a strengthening of the U.S. dollar as
compared to a foreign customers' local currency would effectively increase the
price of the Company's products for that customer, thereby making the
Company's products less attractive to such customers. See "Risk Factors--Risks
Associated with International Markets."
 
  The Company's customer support organization performs network design, product
installation, network optimization, training, consulting and repair and
maintenance services to support its SpotLight 2000 system. The Company offers
consulting services to optimize the network following the SpotLight 2000
system installation. Optimizing a network requires expertise in RF network
design, individual network peculiarities and knowledge of the SpotLight 2000
system capabilities. The Company offers repair and maintenance services. The
Company's warranties vary by customer and range from 12 to 18 months. Warranty
obligations and other maintenance services for the Company's products are
performed at the Company's headquarters in Redmond, Washington.
 
  As of June 30, 1998, the Company had approximately $5.0 million of
unrecognized revenue for customer sales that are subject to the satisfaction
of customer acceptance conditions set forth in the sales agreements related
thereto. In addition, the Company's backlog of orders was approximately
$802,000 on June 30, 1998, compared to no backlog of orders on June 30, 1997.
The Company includes in backlog only customer commitments for which it has
received signed purchase orders and scheduled shipment dates within the
following six months. The Company intends to increase its manufacturing
capacity and believes that backlog will decrease, as a percentage of sales, as
the Company becomes able to fill orders on a more timely basis. Moreover,
product orders in the Company's current backlog are subject to changes in
delivery schedules or to cancellation at the option of the purchaser without
significant penalty. Accordingly, although useful for scheduling production,
backlog as of any particular date may not be a reliable measure of sales for
any future period. See "Risk Factors--Significant Fluctuations in Operating
Results."
 
  Because of the limited size of the Company's customer base and the
relatively large dollar amount of customer orders, revenues derived from a
small number of customers will likely represent a significant
 
                                      43
<PAGE>
 
portion of revenue in any given period. A decrease in demand for the Company's
systems from any customer for any reason is likely to result in significant
periodic fluctuations in revenue. Due to the highly concentrated nature of the
cellular industry, the Company believes that the number of potential customers
for future products, if any, will be small. Failure by the Company to capture
a significant number of the cellular network operators as customers could have
a material adverse effect on the Company's business and operating results. See
"Risk Factors--Significant Fluctuations in Operating Results," "--Significant
Customer Concentration."
 
RESEARCH AND DEVELOPMENT
 
  The Company's research and development efforts focus primarily on enhancing
the features and functionality, improving the quality and reducing the
manufacturing cost of the SpotLight 2000 system. The Company's efforts also
focus on using existing product architecture and technology to maintain
commonality and minimize time-to-market for new product enhancements and
technology platforms. The Company is investing resources in extending the
SpotLight 2000 system to other principal manufacturers' base station equipment
both in the United States and abroad. The Company is also investing resources
in the development of a spectrum management platform for GSM and in early-
stage research regarding CDMA for PCS and TDMA.
 
  Research and development expenses were approximately $883,000, $7.2 million
and $13.1 million for the fiscal years ended December 31, 1995, 1996 and 1997,
respectively, and $8.0 million for the six months ended June 30, 1998. The
Company believes that continued investment in research and development is
critical to attaining its strategic objectives and, as a result, expects
research and development expenses to increase in absolute dollars for the
foreseeable future. As of June 30, 1998, 91 employees were engaged in the
Company's research, development and product management efforts.
 
  The market for the Company's current product and planned future products is
subject to rapid technological change, frequent new product introductions and
enhancements, product obsolescence, changes in customer requirements and
evolving industry standards. To be competitive, the Company must successfully
develop, introduce and sell new products or product enhancements that respond
to changing customer requirements on a timely and cost-effective basis. The
Company's success in developing new and enhanced products will depend on a
variety of factors, many of which are beyond the Company's control. Such
factors include the timely and efficient completion of system design; the
timely and efficient implementation of assembly, calibration and test
processes; sourcing of components; the development and completion of related
software; the reliability, cost and quality of new products; the degree of
market acceptance; and the development and introduction of competitive
products by competitors. The inability of the Company to introduce in a timely
manner new products or product enhancements that contribute to sales could
have a material adverse effect on the Company's business and operating
results. See "Risk Factors--Rapid Technological Change and Requirement for
Frequent New Product Introductions."
 
MANUFACTURING
 
  The Company relies to a substantial extent on outside suppliers to
manufacture many of the components and subassemblies used in the SpotLight
2000 system. The Company's manufacturing operations consist primarily of
supplier and commodity management and assembling finished goods from
components and subassemblies purchased from such outside suppliers. The
Company monitors quality at each stage of the production process, including
the selection of component suppliers, the assembly of finished goods and final
testing, packaging and shipping. The Company considers quality, cost and
timing of delivery in selecting its component suppliers. Final assembly,
system integration and full-configuration testing operations are performed at
the Company's headquarters in Redmond, Washington.
 
  Certain parts and components used in the Company's products, including
linear power amplifiers supplied by Powerwave, are presently only available
from a sole source. In addition, the Company is
 
                                      44
<PAGE>
 
currently dependent upon Sanmina as the primary source for the supply of the
Company's printed circuit board assemblies. Certain other parts and components
used in the Company's products are available from a limited number of sources.
The Company's reliance on these sole source or limited source suppliers
involves certain risks and uncertainties, including the possibility of a
shortage or discontinuation of certain key components and reduced control over
delivery schedules, manufacturing capability, quality and cost. Any reduced
availability of such parts or components when required could materially impair
the Company's ability to manufacture and deliver its products on a timely
basis and result in the cancellation of orders which could have a material
adverse effect on the Company's business and operating results. See "Risk
Factors--Sole Source Suppliers; Dependence on Key Suppliers."
 
  The Company has had only limited experience manufacturing and arranging for
the manufacture of its products, and there can be no assurance that the
Company or any manufacturer of the Company's products will be successful in
increasing its manufacturing volume. The Company may need to procure
additional manufacturing facilities and equipment, adopt new inventory
controls and procedures, substantially increase its personnel and revise its
quality assurance and testing practices, and there can be no assurance that
any of these efforts will be successful. See "Risk Factors--Limited
Manufacturing Experience; No Assurance of Successful Expansion of Operations"
and "--Risks Associated with International Markets."
 
COMPETITION
 
  The market for spectrum management solutions is relatively new but is
expected to become increasingly competitive. The Company's products compete
with other smart antenna systems and alternative wireless infrastructure
devices such as repeaters, cryogenic filters and tower-top amplifiers. The
Company believes that the principal competitive factors are the cost-effective
delivery of increased capacity, expanded coverage and improved system quality
to cellular network operators. There can be no assurance that the Company will
compete favorably with respect to the foregoing factors.
 
  The Company believes that base station manufacturers, who provide cellular
network capacity through sales of additional base stations, represent a
significant competitive threat to the Company. These manufacturers, including
Ericsson, Lucent, Motorola, Nokia, Northern Telecom and Siemens, have
long-term, established relationships with the cellular network operators.
Deployment of the Company's SpotLight 2000 system by cellular network
operators can improve base station performance, and therefore may result in
fewer sales opportunities for base station manufacturers. Smart antenna
technology represents an area of opportunity for such manufacturers. The
Company believes that certain of these manufacturers are developing smart
antenna systems and are likely to offer smart antenna capabilities in the
future. In addition to having more established relationships with cellular
network operators, these manufacturers have significantly greater financial,
technical, manufacturing, sales, marketing and other resources than the
Company and significantly greater name recognition for their existing products
and technologies than the Company.
 
  The Company's current primary direct competitors for spectrum management
solutions are Celwave (a division of Radio Frequency Systems Inc. which is an
affiliate of Alcatel Alsthom S.A.), ArrayComm, Inc. and GEC-Marconi Hazeltine
Corporation. In addition, other companies, such as Raytheon E-Systems,
Watkins-Johnson Company, Texas Instruments Incorporated and ARGOSystems, Inc.
(a subsidiary of the Boeing Company), offer systems that utilize digital
signaling processing and interference cancellation techniques to extend cell
site coverage and improve call quality. Several companies offer alternative
technologies such as cryogenic filters, tower-top low noise amplifiers and
repeaters that can be used to provide service in network coverage holes and
improve call quality. The Company may also face competition in the future from
new market entrants offering competing technologies.
 
  The Company believes that its ability to compete in the future will depend
in part on a number of competitive factors outside its control, including the
development by others of products that are competitive with the Company's
products and the price at which others offer comparable products. To
 
                                      45
<PAGE>
 
be competitive, the Company will need to continue to invest substantial
resources in research and development and sales and marketing. There can be no
assurance that the Company will have sufficient resources to make such
investments or that the Company will be able to make the technological
advances necessary to remain competitive. Accordingly, there can be no
assurance that the Company will be able to compete successfully in the future.
See "Risk Factors--Competition."
 
INTELLECTUAL PROPERTY
 
  The Company relies on a combination of patent, trade secret, copyright and
trademark protection, nondisclosure agreements and other measures to protect
its proprietary rights. The Company currently has eight issued U.S. patents
and 25 pending U.S. patent applications. The Company's future success will
depend in large part on its ability to obtain patent protection, in the U.S.
and other world markets to defend patents once obtained, to maintain trade
secrets and to operate without infringing upon the patents and proprietary
rights of others. The patent positions of companies in the worldwide wireless
communications industry, including the Company, are generally uncertain and
involve complex legal and factual questions. There can be no assurance that
any issued patents owned by or licensed to the Company will not be challenged,
invalidated or circumvented, or that the rights granted thereunder will
provide competitive advantages to the Company. Further, there can be no
assurance that patents will issue from any patent applications or that, if
patents do issue, the claims allowed would be sufficiently broad to protect
the Company's technology. In addition, there can be no assurance that patents
issued in the U.S. will receive corresponding patent coverage in foreign
markets or that the Company will pursue similar patent coverage in all foreign
markets.
 
  Patents and patent applications relating to products used in the worldwide
wireless communications industry are numerous and current and potential
competitors and other third parties may have filed or may in the future file
applications for, or may have been issued or in the future may be issued,
patents or may obtain additional proprietary rights relating to products used
or proposed to be used by the Company. The Company may not be aware of all
patents or patent applications that may materially affect the Company's
ability to make, use or sell any current or future products. From time to
time, third parties have asserted patent, copyright and other intellectual
property rights to technologies that are important to the Company. The Company
expects that it will increasingly be subject to infringement claims as the
number of products and competitors in the spectrum management market grows and
the functionality of products overlaps. Third parties may assert infringement
claims against the Company in the future, and such assertions could result in
costly litigation or require the Company to obtain a license to intellectual
property rights of such parties. There can be no assurance that any such
licenses would be available on terms acceptable to the Company, if at all. Any
failure to obtain a license from any third party asserting claims in the
future or defense of any third party lawsuit could have a material adverse
effect on the Company's business and operating results.
 
  The Company also relies on unpatented trade secrets to protect its
proprietary technology, and there can be no assurance that others will not
independently develop or otherwise acquire the same or substantially
equivalent technologies or otherwise gain access to the Company's proprietary
technology or disclose such technology or that the Company can ultimately
protect its rights to such unpatented proprietary technology. Further, third
parties may obtain patent rights to such unpatented trade secrets, which
patent rights could be used to assert infringement claims against the Company.
The Company also relies on confidentiality agreements with its employees,
vendors, consultants and customers to protect its proprietary technology.
There can be no assurance that these agreements will not be breached, that the
Company would have adequate remedies for any breach or that the Company's
trade secrets will not otherwise become known to or be independently developed
by competitors. Failure to obtain or maintain patent and trade secret
protection, for any reason, could have a material adverse effect on the
Company's business and operating results. See "Risk Factors--Uncertainty
Regarding Protection of Intellectual Property."
 
                                      46

GOVERNMENT REGULATION
 
  Wireless communications are subject to extensive regulation by foreign and
U.S. laws and international treaties. The Company's systems must conform to
certain international and domestic regulations established to, among other
things, avoid interference among users of frequencies. In order for the
Company's products to be used, regulatory approval must be obtained. This
governmental approval process frequently involves substantial delay which
could result in the cancellation, postponement or rescheduling of products by
the Company's customers, which in turn may have a material adverse effect on
the sale of systems by the Company to such customers. The Company believes
that its SpotLight 2000 system currently complies with all applicable U.S. and
foreign regulations in countries in which its sales are material, but changes
in these regulations, the need to comply with regulations in additional
countries in the event of sales into those countries, or a failure to obtain
necessary approvals or permits in connection with sales to service providers
in a country could require the Company to change the features of its SpotLight
2000 system and thereby incur substantial costs and experience delays in
system installation or operation. Regulatory bodies frequently promulgate new
standards and regulations for wireless communications systems and products. To
the extent that the Company's customers are delayed in deploying these
cellular systems as a result of such new standards or regulations, the Company
could experience delays in orders. These delays could have a material adverse
effect on the Company's business and operating results.
 
  The regulatory environment in which the Company operates is subject to
significant change. Regulatory changes, which are affected by political,
economic and technical factors, could significantly affect the Company's
operations by restricting network development efforts by the Company's
customers or end users, making current systems obsolete or increasing the
opportunity for additional competition. Any such regulatory changes could have
a material adverse effect on the Company's business and operating results. The
Company might deem it necessary or advisable to modify its systems to operate
in compliance with such regulations. Such modifications could be expensive and
time-consuming. See "Risk Factors--Government Regulation."
 
EMPLOYEES
 
  As of June 30, 1998, the Company had 200 employees of which 91 were
primarily engaged in research, development and product management, 34 in
manufacturing, 43 in sales, marketing and customer support and 32 in general
and administration. The Company has no collective bargaining agreement with
its employees and the Company has never experienced a work stoppage. The
Company believes that its employee relations are good. See "Risk Factors--
Management of Growth; New Management Team" and "--Dependence on Attraction and
Retention of Key Personnel."
 
FACILITIES
 
  The Company is headquartered in Redmond, Washington, where it leases an
aggregate of approximately 96,000 square feet, housing its principal
administrative, sales and marketing, customer support and manufacturing
facilities. The Company's lease for such facility expires on May 31, 2005 and
the Company has an option to renew such lease for two additional five year
terms. In addition, the Company has sales and service offices in Dallas and
Washington, D.C. that are subject to short-term leases.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  The Company's Certificate of Incorporation limits the liability of directors
to the maximum extent permitted by the Delaware General Corporation Law (the
"DGCL"). The DGCL provides that a director of a corporation will not be
personally liable for monetary damages for breach of such individual's
fiduciary duties as a director except for liability (i) for any breach of such
director's duty of loyalty to the Company or to its stockholders, (ii) for
acts or omissions not in good faith or that involve intentional misconduct or
a knowing violation of law, (iii) for unlawful payments of dividends or
unlawful stock repurchases or redemptions or (iv) for any transaction from
which a director derives an improper personal benefit.
 
  The Company's Bylaws provide that the Company shall indemnify its directors
and officers and may indemnify its other employees and agents to the fullest
extent permitted by law. The Company believes that indemnification under its
Bylaws covers at least negligence and gross negligence on the part of an
indemnified party. The Company's Bylaws also permit the Company to advance
expenses incurred by an indemnified party in connection with the defense of
any action or proceeding arising out of such party's status or service as a
director, officer, employee or other agent of the Company upon an undertaking
by such party to repay such advances if it is ultimately determined that such
party is not entitled to indemnification, such advancement of expenses is
subject to authorization by the Board of Directors in the case of non-
executive officers, employees and agents.
 
  The Company has entered into separate indemnification agreements with each
of its directors and officers. These agreements require the Company, among
other things, to indemnify such director or officer against expenses
(including attorney's fees), judgments, fines and settlements (collectively,
"Liabilities") paid by such individual in connection with any action, suit or
proceeding arising out of such individual's status or service as a director or
officer of the Company (other than Liabilities arising from willful misconduct
or conduct that is knowingly fraudulent or deliberately dishonest) and to
advance expenses incurred by such individual in connection with any proceeding
against such individual with respect to which such individual may be entitled
to indemnification by the Company. The Company believes that its Certificate
of Incorporation and Bylaw provisions and indemnification agreements are
necessary to attract and retain qualified persons as directors and officers.
The Company also maintains directors' and officers' liability insurance.
 
  At present the Company is not aware of any pending litigation or proceeding
involving any director, officer, employee or agent of the Company where
indemnification will be required or permitted. The Company is not aware of any
threatened litigation or proceeding that might result in a claim for such
indemnification.

(1) As a result of his separation from the Company, all unexercised options
    held by Mr. Daley had expired as of December 31, 1997. Mr. Huseby did not
    hold any options as of December 31, 1997.
(2) All options to be granted under the 1998 Stock Option Plan and all options
    granted after July 15, 1997 under the 1995 Stock Option Plan may be
    exercised immediately upon grant and prior to full vesting, subject to the
    optionee's entering into a restricted stock purchase agreement with the
    Company with respect to any unvested shares. Under such agreement, the
    optionee grants the Company an option to repurchase any unvested shares at
    their original purchase price in the event the optionee's employment or
    consulting relationship with the Company is terminated. The Company's
    right of repurchase lapses as the shares vest in a series of equal monthly
    or annual installments in accordance with the vesting schedule of the
    exercised options.
(3) Based on an assumed initial public offering price of $10.50 per share,
    minus the exercise price, multiplied by the number of shares underlying
    the option.
 
  The Company has not granted options to purchase Common Stock to any of the
Named Executive Officers in 1998.
 
SEVERANCE ARRANGEMENTS
 
  The Company has entered into severance arrangements with Douglas O. Reudink,
Chief Technical Officer, Robert H. Hunsberger, President and Chief Executive
Officer, Vito E. Palermo, Senior Vice President and Chief Financial Officer,
and Richard Henderson, Vice President of Sales and Marketing.
 
  On July 7, 1995, in connection with the Series A Preferred Stock financing,
the Company entered into an agreement with Dr. Reudink which provides that if
the Company were to terminate his employment without cause after July 7, 1996,
the Company would be obligated to make a lump-sum payment to Dr. Reudink equal
to six months' of his then-current base salary and to provide benefits for six
months following termination. In connection with this agreement, Dr. Reudink
entered into a one-year non-competition agreement effective upon the
termination of his employment with the Company.
 
  On June 27, 1997, in connection with the employment of Mr. Hunsberger, the
Company entered into an arrangement with Mr. Hunsberger which provides that if
the Company were to terminate his employment without cause, the Company would
be obligated to make a lump-sum payment to Mr. Hunsberger equal to twelve
months' of his then-current base salary and provide benefits for twelve months
following termination.
 
  On July 23, 1997, in connection with the employment of Mr. Palermo, the
Company entered into an agreement with Mr. Palermo which provides that if the
Company were to terminate his employment without cause after January 20, 1998,
the Company would be obligated to make a lump-sum payment to Mr. Palermo equal
to six months' of his then-current base salary and 50% of his target bonus, if
any, for the year in which the termination occurs and to provide benefits for
six months following termination. In addition, Mr. Palermo's stock options
would continue to vest in accordance with the Company's 1995 Stock Option
Plan, as amended from time to time, during the period that Mr. Palermo would
receive continued benefits from the Company. Mr. Palermo's voluntary
resignation will not constitute termination without cause unless Mr. Palermo
were to resign for good reason, in which case the Company would be
 
                                      54
<PAGE>
 
obligated to make a lump-sum payment to Mr. Palermo equal to nine months' of
his then-current base salary and to pay for the reasonable cost of relocating
Mr. Palermo back to his primary residence. If the Company were to terminate
Mr. Palermo within six months following certain changes in control of the
Company, the Company would pay to Mr. Palermo an amount equal to twelve
months' of his then-current base salary and 100% of his target bonus for the
year in which the change in control transaction occurs. In addition, Mr.
Palermo's outstanding unvested stock options would vest during such period in
accordance with the Company's stock option plan as in effect at that time.
 
  On October 29, 1997, in connection with the employment of Mr. Henderson, the
Company entered into an agreement with Mr. Henderson which provides that if
the Company were to terminate his employment without cause, the Company would
be obligated to make a lump-sum payment to Mr. Henderson equal to six months'
of his then-current base salary.
 
STOCK PLANS
 
  1998 Stock Option Plan and 1995 Third Amended and Restated Stock Option
Plan. The 1998 Stock Option Plan (the "1998 Stock Option Plan") was adopted by
the Board of Directors in May 1998 and is expected to be approved by the
stockholders of the Company prior to the completion of this offering. A total
of 850,000 shares of Common Stock has been reserved for issuance under the
1998 Stock Option Plan, and, as of June 30, 1998, all such shares remained
available for grant under the 1998 Stock Option Plan. On the first trading day
of each of the five calendar years beginning in 1999 and ending in 2003, the
number of shares reserved for issuance under the 1998 Stock Option Plan shall
automatically be increased by an amount equal to three percent (3%) of the
Company's outstanding Common Stock, up to a maximum of 1,000,000 shares in any
calendar year, or such lower amount as determined by the Board of Directors.
 
  The 1995 Third Amended and Restated Stock Option Plan (the "1995 Stock
Option Plan") was originally adopted by the Board of Directors in August 1995
and was approved by the stockholders of the Company in January 1996. The 1995
Stock Option Plan was amended by the Board of Directors in December 1995,
February 1997, July 1997 and May 1998 and such amendments were approved by the
stockholders in January 1996, February 1997 and July 1997. A total of
4,150,000 shares of Common Stock has been reserved for issuance under the 1995
Stock Option Plan, and, as of June 30, 1998, 435,189 options remain available
for grant under such plan.
 
  Both the 1998 Stock Option Plan and the 1995 Stock Option Plan provide for
the grant to employees of the Company (including officers and employee
directors) of "incentive stock options" within the meaning of Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code") and for the grant
of nonstatutory stock options to employees, officers, directors (including
non-employee directors) and consultants of the Company. 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 (under all plans of the Company and determined for each share as
of the date the option to purchase the share was granted) in excess of
$100,000, any such excess options shall be treated as nonstatutory options.
 
  Both the 1998 Stock Option Plan and the 1995 Stock Option Plan are
administered by the Board of Directors or a committee of the Board of
Directors (the "Administrator"). The Administrator determines the terms of
options granted under the 1998 Stock Option Plan and 1995 Stock Option Plan,
including the number of shares subject to the option, exercise price, term and
exercisability. The exercise price of all incentive stock options granted
under either the 1998 Stock Option Plan or 1995 Stock Option Plan must be at
least equal to the fair market value of the Common Stock of the Company on the
date of grant. The exercise price of any incentive stock option granted to an
optionee who owns stock representing more than 10% of the voting power of the
Company's outstanding capital stock (a "10% Stockholder") must be at least
equal to 110% of the fair market value of the Common Stock on the date of
grant. The
 
                                      55
<PAGE>
 
exercise price of all nonstatutory stock options cannot be less than 85% of
the fair market value of the Common Stock of the Company on the date of grant,
except in the case of 10% Stockholders, in which case the exercise price
cannot be less than 110% of the fair market value of the Common Stock. Payment
of the exercise price, subject to approval by the Administrator, may be made
in cash, check, promissory note, delivery of shares of the Company's Common
Stock, subject to certain conditions, net exercise of the option, delivery of
an irrevocable subscription agreement that obligates the option holder to take
and pay for the shares issuable upon exercise not more than 12 months after
the date of delivery of the subscription agreement, any combination of the
foregoing, or other consideration approved by the Administrator. The term of
options granted under either the 1998 Stock Option Plan or the 1995 Stock
Option Plan may not exceed 10 years; provided, however, that the term of an
incentive stock option granted to a 10% stockholder may not exceed five years.
An option may not be transferred by the optionee other than by will or the
laws of descent or distribution. Each option may be exercised during the
lifetime of the optionee only by such optionee or by a permitted transferee.
Options granted to each employee under either the 1998 Stock Option Plan or
the 1995 Stock Option Plan generally become exercisable at the rate of 25% of
the total number of shares subject to the options after the first anniversary
following the date of grant, with 1/48th vesting monthly thereafter.
 
  The Board of Directors has the authority to amend or terminate both the 1998
Stock Option Plan and the 1995 Stock Option Plan as long as such action does
not adversely affect any outstanding option and provided that, to the extent
necessary and desirable to comply with Rule 16b-3 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act") or Section 422 of the Code,
stockholder approval shall be obtained for any amendment to either the 1998
Stock Option Plan or the 1995 Stock Option Plan. If not terminated earlier,
the 1998 Stock Option Plan will terminate in 2008 and the 1995 Stock Option
Plan will terminate in 2007.
 
  With respect to all options granted under the 1998 Stock Option Plan and
those options granted on or after February 12, 1997 under the 1995 Stock
Option Plan, in the event of certain changes in control of the Company (a
"Corporate Transaction"), an optionee is, provided such optionee is employed
at the time such Corporate Transaction occurs, entitled to accelerated vesting
of one year if such optionee has been employed by the Company less than two
years or accelerated vesting of two years if such optionee has been employed
by the Company for two years or more as of the date of the Corporate
Transaction; provided, however, this acceleration shall not occur if the
Administrator determines that the Board, the acquiring person or the surviving
corporation, as the case may be, has made equitable and appropriate provision
for the assumption of existing options or substitution of new options on terms
which are equivalent to the foregone option.
 
  The Board has the discretion to authorize the issuance of unvested shares of
Common Stock pursuant to the exercise of all stock options granted under the
1998 Stock Option Plan and any stock options granted after July 15, 1997 under
the 1995 Stock Option Plan. If the optionee ceases to be employed by or
provide services to the Company, all shares of Common Stock issued on exercise
of a stock option which are unvested at the time of cessation shall be subject
to repurchase by the Company at the exercise price paid for such shares (the
"Company Repurchase Right"). The terms and conditions upon which the
repurchase rights are exercisable by the Company are determined by the Board
and set forth in the agreement evidencing such right. The Board has
discretionary authority to cancel the Company's outstanding repurchase rights
with respect to the shares purchased or purchasable under an option granted
pursuant to such plans. In the event of a Corporate Transaction, if vesting of
the options accelerates, the repurchase rights of the Company with respect to
shares previously acquired on exercise of options granted under such plans
shall terminate.
 
  1998 Employee Stock Purchase Plan. The Company's Purchase Plan was adopted
by the Board of Directors in May 1998 and will be submitted for approval by
the stockholders prior to completion of this offering. A total of 500,000
shares of Common Stock has been reserved for issuance under the Purchase Plan.
The Purchase Plan, which is intended to qualify under Section 423 of the Code,
generally will be
 
                                      56
<PAGE>
 
implemented in a series of offering periods of 12 months duration with new
offering periods (other than the first offering period) commencing on or about
February 1 and August 1 of each year. Each offering period will consist of two
consecutive purchase periods of six months duration, with the last day of each
period being designated a purchase date. However, the first such offering
period is expected to commence on the date of this Offering and continue
through July 31, 1999, with the first purchase date occurring on January 31,
1999, and subsequent purchase dates to occur every six months thereafter. The
Purchase Plan will be administered by the Board of Directors or by a committee
appointed by the Board of Directors. Employees (including officers and
employee directors) of the Company, or of any subsidiary designated by the
Board of Directors, are eligible to participate if they are employed by the
Company or any such subsidiary for at least 20 hours per week and more than
five months per year. The Purchase Plan permits eligible employees to purchase
Common Stock through payroll deductions, which may not exceed 15% of an
employee's compensation, at a price equal to the lower of 85% of the fair
market value of the Company's Common Stock at the beginning of the offering
period or the purchase date; provided, however, an employee shall not be
permitted to purchase more than 2,500 shares of Common Stock in any single
purchase period. If the fair market value of the Common Stock on a purchase
date is less than the fair market value at the beginning of the offering
period, a new 12-month offering period will automatically begin on the first
business day following the purchase date with a new fair market value.
Employees may end their participation in the offering at any time during the
offering period, and an employee's participation ends automatically on
termination of employment with the Company. In addition, participants may
decrease their level of payroll deductions once during an offering period.
 
  The Purchase Plan provides that in the event of a merger of the Company with
or into another corporation or a sale of substantially all of the Company's
assets, each right to purchase Common Stock under the plan will be assumed or
an equivalent right substituted by the successor corporation unless the Board
of Directors shortens the offering period so that employees' rights to
purchase stock under the plan are exercised prior to the merger or sale of
assets. On the first trading day of each of the five calendar years beginning
in 1999 and ending in 2003, the number of authorized shares shall
automatically increase by an amount equal to two percent (2%) of the Company's
outstanding Common Stock, up to a maximum of 375,000 shares in any calendar
year, or such lower amount as determined by the Board of Directors. The Board
of Directors has the power to amend or terminate the Purchase Plan as long as
such action does not adversely affect any outstanding rights to purchase stock
thereunder. If not terminated earlier, the Purchase Plan will have a term of
20 years.
 
  1998 Directors' Stock Option Plan. The Directors' Plan was adopted by the
Board of Directors in February 1998 and approved by the stockholders on April
20, 1998. A total of 300,000 shares of Common Stock has been reserved for
issuance under the Directors' Plan. The Directors' Plan provides for the
automatic grant of nonstatutory stock options to nonemployee directors of the
Company. The Directors' Plan is designed to work automatically without
administration; however, to the extent administration is necessary, it will be
performed by the Board of Directors.
 
  The Directors' Plan provides that each person who becomes a nonemployee
director of the Company after the date of this offering shall be granted a
nonstatutory stock option to purchase 25,000 shares of Common Stock (the
"First Option") on the date on which the optionee first becomes a nonemployee
director of the Company. However, for individuals already serving as
nonemployee directors as of the date of this offering, the First Option shall
be an option to purchase 18,000 shares of Common Stock, except in the case of
Messrs. Jarvis, Edwards and Twyver who were granted options to purchase
25,000 shares of Common Stock on February 12, 1998, May 19, 1998 and May 19,
1998, respectively. Thereafter, on the date of each annual meeting of the
Company's stockholders following which a nonemployee director is serving on
the Board of Directors, each nonemployee director (including directors who
were not granted a First Option prior to the date of such annual meeting)
shall be granted an option to purchase 7,000 shares of Common Stock (a
"Subsequent Option") if, on such date, he or she has served on the Company's
Board of Directors for at least six months.
 
                                      57
<PAGE>
 
  The Directors' Plan sets neither a maximum nor a minimum number of shares
for which options may be granted to any one nonemployee director, but does
specify the number of shares that may be included in any grant and the method
of making a grant. No option granted under the Directors' Plan is transferable
by the optionee other than by will or the laws of descent or distribution or
pursuant to a qualified domestic relations order, or to a family trust or
family limited partnership established by the optionee, a member of optionee's
immediate family or to a partnership or other entity of which optionee is a
general partner or plays a similar role. Each option is exercisable, during
the lifetime of the optionee, only by such optionee or by a permitted
transferee. Provided an individual remains a director, the Directors' Plan
provides that each First Option and Subsequent Option shall become exercisable
in installments cumulatively as to 25% of the total number of shares subject
to the Option on the first anniversary of the date of grant of the Option and
1/48th of the total number of shares subject to the Option each month
thereafter. 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. The fair market
value of any option granted concurrently with the initial effectiveness of the
Purchase Plan shall be the Price to Public set forth in the final prospectus
relating to this offering. Options granted under the Directors' Plan have a
term of ten years.
 
  In the event of a Corporate Transaction, an optionee is, provided such
optionee continues to serve as a director until such Corporate Transaction
occurs, entitled to accelerated vesting of one year if such optionee has been
a director of the Company less than two years or accelerated vesting of two
years if such optionee has been a director of the Company for more than two
years as of the date of the Corporate Transaction; provided, however, this
acceleration shall not occur if the Administrator determines that the Board,
the acquiring person or the surviving corporation, as the case may be, has
made equitable and appropriate provision for the assumption or substitution of
new options on terms which are equivalent to the foregone option. The Board of
Directors may amend or terminate the Directors' Plan; provided, however, that
no such action may adversely affect any outstanding option, and the provisions
regarding the grant of options under the plan may be amended only once in any
six-month period, other than to comport with changes in the Code. If not
terminated earlier, the Directors' Plan will have a term of ten years.
 
  401(k) Plan. The Company maintains a 401(k) plan that covers all employees
who satisfy certain eligibility requirements relating to minimum age, length
of service and hours worked. Under the profit-sharing portion of the plan, the
Company may make an annual contribution for the benefit of eligible employees
in an amount determined by the Board of Directors. The Company has not made
any such contribution to date. Under the 401(k) plan, eligible employees may
make pretax elective contributions of up to 15% of their compensation, subject
to maximum limits on contributions prescribed by law.

E. Palermo, Senior Vice President and Chief Financial Officer of the Company
pursuant to a Promissory Note bearing interest at a rate of 5.50% per annum.
Fifty thousand dollars of the principal amount of the loan is to be forgiven
over a three-year period provided that Mr. Palermo remains employed with the
Company with the remaining balance of $25,000 due on the earlier of October
22, 2000 or the date his employment terminates. The maximum indebtedness under
the Promissory Note during the six-month period ended June 30, 1998 was

      options is subject to repurchase by the Company at the original exercise

                           DESCRIPTION OF SECURITIES
 
  Following the closing of the sale of the shares of Common Stock offered
hereby, the authorized capital stock of the Company will consist of
150,000,000 shares of Common Stock, $0.001 par value, and 15,000,000 shares of
Preferred Stock, $0.001 par value.
 
COMMON STOCK
 
  As of June 30, 1998, there were 16,166,277 shares of Common Stock
outstanding that were held of record by approximately 41 stockholders. There
will be 21,166,277 shares of Common Stock outstanding (assuming no exercise of
outstanding options after June 30, 1998) after giving effect to the sale of
the shares of Common Stock offered hereby.
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. 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. See "Dividend Policy." In the event of a liquidation, dissolution or
winding up of the Company, 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
 
  The Board of Directors is authorized to issue up to 15,000,000 shares of
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,
including dividend rights, dividend rates, conversion rights, voting rights,
terms of redemption, redemption prices, liquidation preferences and the number
of shares constituting any series or the designation of such series, without
any further vote or action by the stockholders.
 
  The issuance of Preferred Stock may have the effect of delaying, deferring
or preventing a change in control of the Company without further action by the
stockholders and may adversely affect the voting and other rights of the
holders of Common Stock. In certain circumstances, such issuance could have
the effect of decreasing the market price of the Common Stock. As of the
closing of this offering, no shares of Preferred Stock will be outstanding and
the Company currently has no plans to issue any shares of Preferred Stock.

  As of June 30, 1998, the Company has warrants outstanding to purchase an
aggregate of 65,416 shares of Series A Preferred Stock, 19,999 shares of

the Company issued a warrant to purchase up to an aggregate of 48,750 shares
of Series A Preferred Stock to Comdisco, Inc. ("Comdisco") at an exercise
price of $2.1875 per share. The warrant expires on the later of December 13,

equipment lease line entered into in August 1996, the Company
 
                                      63
<PAGE>
 
issued a warrant to purchase up to an aggregate of 19,999 shares of Series B

line entered into in June 1997, the Company issued a warrant to purchase up to
an aggregate of 34,090 shares of Series C Preferred Stock to Comdisco at an
exercise price of $6.16 per share. The warrant expires on the later of June 9,
2004 or 18 months following the effective date of this offering.
 
  In connection with the issuance of the 13.75% Senior Secured Bridge Notes in
April 1998, the Company issued the holders of the 13.75% Senior Secured Bridge
Notes warrants to purchase an aggregate of 537,500 shares of Series D
Preferred Stock at a purchase price of $0.01 per share (the "Note Warrants").
The Note Warrants expire on April 28, 2000.

Investments Corporation in April 1998, the Company issued a warrant to
purchase up to an aggregate of 4,375 shares of Series D Preferred Stock at an
exercise price of $8.00 per share. The warrant expires on the closing of this
offering and is expected to be net exercised simultaneously therewith.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
  The holders of 15,338,305 shares of Common Stock (the "Registrable
Securities") or their transferees are entitled to certain rights with respect
to the registration of such shares under the Securities Act. These rights are
provided under the terms of an agreement between the Company and the holders
of Registrable Securities. Subject to certain limitations in the agreement,
certain holders of the Registrable Securities may require, on two occasions at
any time after six months from the effective date of this offering, that the
Company use its best efforts to register the Registrable Securities for public
resale, provided that the proposed aggregate offering price is at least
$7,500,000. If the Company registers any of its Common Stock either for its
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. The holders of the Note Warrants are also entitled to
include shares issuable upon exercise of the Note Warrants 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 the initial public offering. Subject to certain
conditions, all fees, costs and expenses of such registrations must be borne
by the Company 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 OF DELAWARE AND WASHINGTON LAW AND CHARTER DOCUMENTS
 
  The Company is subject to the provisions of Section 203 of the DGCL. In
general, the statute prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date that the person became an interested
stockholder unless (with certain exceptions) the business combination or the
transaction in which the person became an interested stockholder is approved
in a prescribed manner. Generally, a "business combination" includes a merger,
asset or stock sale or other transaction resulting in a financial benefit to
the stockholder, and an "interested stockholder" is a person who, together
with affiliates and associates, owns (or within three years prior, did own)
15% or more of the corporation's outstanding voting stock. This provision may
have the effect of delaying, deferring or preventing a change in control of
the Company without further action by the stockholders.
 
  The laws of the State of Washington, where the Company's principal executive
offices are located, impose restrictions on certain transactions between
certain foreign corporations and significant stockholders. Chapter 23B.19 of
the Washington Business Corporation Act (the "WBCA") prohibits a "target
corporation," with certain exceptions, from engaging in certain "significant
business transactions"
 
                                      64
<PAGE>
 
with a person or group of persons who beneficially own 10% or more of the
voting securities of the target corporation (an "acquiring person") for a
period of five years after such acquisition, unless the transaction or
acquisition of such shares is approved by a majority of the members of the
target corporation's board of directors prior to the time of acquisition. Such
prohibited transactions include, among other things, a merger or consolidation
with, disposition of assets to, or issuance or redemption of stock to or from,
the acquiring person, termination of 5% or more of the employees of the target
corporation as a result of the acquiring person's acquisition of 10% or more
of the shares or allowing the acquiring person to receive disproportionate
benefit as a stockholder. After the five-year period, a significant business
transaction may take place as long as it complies with certain fair price
provisions of the statute. A target corporation includes a foreign corporation
if (i) the corporation has a class of voting stock registered pursuant to
Section 12 or 15 of the Exchange Act, (ii) the corporation's principal
executive office is located in Washington, and (iii) any of (a) more than 10%
of the corporation's stockholders of record are Washington residents, (b) more
than 10% of its shares are owned of record by Washington residents, (c) 1,000
or more of its stockholders of record are Washington residents, (d) a majority
of the corporation's employees are Washington residents or more than 1,000
Washington residents are employees of the corporation, or (e) a majority of
the corporation's tangible assets are located in Washington or the corporation
has more than $50.0 million of tangible assets located in Washington. A
corporation may not "opt out" of this statute and, therefore, the Company
anticipates this statute will apply to it. Depending upon whether the Company
meets the definition of a target corporation, Chapter 23B.19 of the WBCA may
have the effect of delaying, deferring or preventing a change in control of
the Company.
 
  In addition, upon completion of this offering, certain provisions of the
Company's charter documents, including a provision eliminating the ability of
stockholders to take actions by written consent, may have the effect of
delaying or preventing changes in control or management of the Company, which
could have an adverse effect on the market price of the Company's Common
Stock. The Company's stock option and purchase plans generally provide that
upon a change in control or similar event optionees are entitled to
accelerated vesting credit equal to either twelve months or twenty-four months
of additional vesting beyond that otherwise scheduled, based on whether he or
she has been employed by the Company less than two years, or two years or
more, respectively, as of the date of such event unless in connection with the
change in control or similar event, outstanding options are assumed or
substituted for equivalent options of a successor corporation. The Board of
Directors has authority to issue up to 15,000,000 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
stockholders. 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, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding
voting stock of the Company, thereby delaying, deferring or preventing a
change in control of the Company. Furthermore, such Preferred Stock may have
other rights, including economic rights senior to the Common Stock, and, as a
result, the issuance of such Preferred Stock could have a material adverse
effect on the market value of the Common Stock. The Company has no present
plan to issue shares of Preferred Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have outstanding
21,166,277 shares of Common Stock, assuming no exercise of options after June
30, 1998. Of these shares, the 5,000,000 shares sold in this offering will be

Securities Act unless purchased by "affiliates" of the Company as that term is
defined in Rule 144 of the Securities Act.

from registration. All directors and executive officers and certain other

</TABLE>
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for
at least one year, including persons who may be deemed "affiliates" of the
Company, would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of 1% of the number of shares of
Common Stock then outstanding or the average weekly trading volume of the
Common Stock as reported through the Nasdaq National Market during the four
calendar weeks preceding the filing of a Form 144 with respect to such sale.
Sales under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information
about the Company. In addition, a person who is not deemed to have been an
affiliate of the Company at any time during the 90 days preceding a sale, and
who has beneficially owned for at least two years the shares proposed to be
sold, would be entitled to sell such shares under Rule 144(k) without regard
to the requirements described above.

  In general, Rule 701 permits resales of shares issued pursuant to certain
compensatory benefit plans and contracts commencing 90 days after the issuer
becomes subject to the reporting requirements of the Exchange Act in reliance
upon Rule 144 but without compliance with certain restrictions, including the
holding period requirements, contained in Rule 144. During the Lockup Period,
the Company intends to register on a registration statement on Form S-8, (i) a
total of 3,638,399 shares of Common Stock reserved for issuance under the 1995
Stock Option Plan (assuming no exercise of options after June 30, 1998), (ii)
a total of 850,000 shares of Common Stock reserved for issuance under the 1998
Stock Option Plan, (iii) a total of 300,000 shares of Common Stock reserved
for issuance under the Directors' Plan and (iv) a total of 500,000 shares of
Common Stock reserved for issuance under the Purchase Plan. Such registration
will permit the resale of shares so registered by non-affiliates in the public
market without restriction under the Securities Act.
 
  Prior to this offering, there has been no public market for securities of
the Company. No prediction can be made as to the effect, if any, that market
sales of shares or the availability of shares for sale will have on the market
price prevailing from time to time. Nevertheless, sales of substantial amounts
of Common Stock of the Company in the public market after the lapse of the
restrictions described below could adversely affect the prevailing market
price and the ability of the Company to raise equity capital in the future at
a time and price which it deems appropriate. In addition, after this offering,
the holders of 15,338,305 shares of Common Stock (the "Registrable
Securities") will be entitled to certain demand and piggyback rights with
respect to registration of such shares under the Securities Act. Registration
of such shares under the Securities Act would result in such shares becoming
freely tradable without restriction under the Securities Act (except for
shares purchased by affiliates of the Company) immediately upon the
effectiveness of such registration. See "Description of Securities--
Registration Rights of Certain Holders." If such holders, by exercising their
demand registration rights, cause a larger number of securities to be
registered and sold in the public market, such sales could have an adverse
effect on the market price for the Company's Common Stock. If the Company were
to include in a Company initiated registration any Registrable Securities
pursuant to the exercise of piggyback registration rights, such sales may have
an adverse effect on the Company's ability to raise needed capital.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all shares of the Common Stock offered hereby if any such shares are
purchased.
 
  The Company has been advised by Representatives of the Underwriters that
they propose to offer the shares of Common Stock directly 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. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of $   per share to certain other dealers. After the
initial public offering of the shares, the offering price and other selling
terms may be changed by the Representatives of the Underwriters.
 
  The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the date of this Prospectus, to purchase up to an aggregate
of 750,000 additional shares of Common Stock at the public offering price less
the underwriting discounts and commissions set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the
same percentage of such additional shares as the number set forth next to such
Underwriters name in the above table bears to the total number of shares of
Common Stock offered hereby, and the Company will be obligated, pursuant to
the option, to sell shares to the Underwriters to the extent the option is
exercised. The Underwriters may exercise such option only to cover over-
allotments made in connection with the sale of shares of Common Stock offered
hereby. If purchased, the Underwriters will offer such additional shares on
the same terms as those on which the 5,000,000 shares are being offered.
 
  The offering of the shares is made for delivery when, as and if accepted by
the Underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the offering without notice. The Underwriters reserve the
right to reject an order for the purchase of shares in whole or in part.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
  All officers and directors of the Company and certain stockholders have
agreed with the Underwriters that, until 180 days after the effective date of
this Prospectus, they will not directly or indirectly offer, sell, pledge,
contract to sell (including any short sale), grant any option to purchase or
otherwise dispose of any shares of Common Stock (including, without
limitation, shares of Common Stock of the Company which may be deemed to be
beneficially owned by the undersigned on the date hereof in accordance with
the rules and regulations of the Commission and shares of Common Stock which
may be issued upon exercise of a stock option or warrant) or enter into any
hedging transaction relating to the Common Stock.
 
                                      68

The Company has also agreed not to sell, offer to sell, contract to sell,
grant any option to purchase or otherwise dispose of any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for
Common Stock or any rights to acquire Common Stock for a period of 180 days
after the date of this Prospectus without the prior written consent of BT
Alex. Brown Incorporated, except that the Company may issue shares upon the
exercise of options granted prior to the date hereof, and may grant additional
options under its Plans, provided that, without the prior written consent of
BT Alex. Brown Incorporated, such additional options shall be exercisable, but
not transferable, during such period. The lockup agreements may be released at
any time as to all or any portion of the shares subject to such agreements at
the sole discretion of BT Alex. Brown Incorporated.
 
  Prior to this offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price for the Common
Stock will be determined by negotiation between the Company and the
Representatives of the Underwriters. Among the factors to be considered in
such negotiations will be prevailing market conditions, the results of
operations of the Company in recent periods, the market capitalizations and
stages of development of other companies that the Company and the
Representatives of the Underwriters believe to be comparable to the Company,
estimates of the business potential of the Company and its industry in general
and the present state of the Company's development and other factors deemed
relevant.
 
  BT Alex. Brown Incorporated acted as the placement agent in the private
placement of the Company's 13.75% Senior Secured Bridge Notes and Note
Warrants issued on April 28, 1998, and in connection with that placement
received cash compensation. BT Holdings (NY), Inc., an affiliate of BT Alex.
Brown Incorporated, purchased a 13.75% Senior Secured Bridge Note in the
principal amount of $4,500,000 and a Note Warrant to purchase 83,405 shares of
Series D Preferred Stock. See "Certain Relationships and Related Transactions"
for a description of the terms of the 13.75% Senior Secured Bridge Notes and
the Note Warrants.
 
  In view of this relationship, the offering is being made in accordance with
Section 2720 of the Conduct Rules of the National Association of Securities
Dealers, Inc., which provides, among other things, that the price of the
Common Stock can be no higher than that recommended by a "qualified
independent underwriter" meeting certain standards. In accordance with this
requirement, Merrill Lynch, Pierce, Fenner & Smith Incorporated is serving in
such role and will recommend the maximum public offering price of the Common
Stock, Merrill Lynch, Pierce, Fenner & Smith Incorporated has also
participated in the preparation of this Prospectus and has performed due
diligence with respect thereto.
 
  The Company has been advised by the Representatives that during and after
this offering, the Underwriters may purchase and sell Common Stock in the open
market. These transactions may include over-allotment and stabilizing
transactions and purchases to cover syndicate short positions created in
connection with this offering. Stabilizing transactions consist of certain
bids or purchases for the purpose of preventing or retarding a decline in the
market price of the Common Stock; and syndicate short positions involve the
sale by the Underwriters of a greater number of shares of Common Stock than
they are required to purchase from the Company in this offering. The
Underwriters also may impose penalty bids, whereby selling concessions allowed
to the syndicate members or other broker-dealers in respect of the Common
Stock sold in this offering for their account may be reclaimed by the
syndicate if such securities are repurchased by the syndicate in stabilizing
or short-covering transactions. These activities may stabilize, maintain or
otherwise affect the market price of the Common Stock, which may be higher
than the price that might otherwise prevail in the open market. These
transactions may be effected on the Nasdaq National Market or otherwise and
these activities, if commenced, may be discontinued at any time.
 
  The Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm orders to any account over which they
exercise discretionary authority.

REUSE/FREQUENCY REUSE.......  The utilization of frequency (channels) more than once in a
                              wireless network. To minimize interference, cells are
                              assigned only a portion of an operator's available
                              frequencies; adjacent cells do not use the identical
                              channels. The reuse pattern determines how many cells the
                              available frequencies are divided among before being reused
                              and therefore how much distance separates cells using the
                              same frequency.
RF (RADIO FREQUENCY)........  The range of electromagnetic frequencies above the audio
                              range and below visible light. All broadcast transmission,
                              from AM radio to microwaves, falls into this range, which is
                              between 30-KHz and 300-GHz.
RF SIGNAL...................  Information transmitted over a communications network by a

                              calls in places outside a user's home coverage area.
SECTORIZING.................  The process of dividing a cell site into sectors by using
                              directional antennas. Sectorizing is typically used as a
                              means of reducing interference in order to increase
                              frequency reuse and therefore network capacity.
SECTOR SYNTHESIS............  A proprietary method incorporated into Metawave's smart
                              antenna system to better control the transmission and
                              reception of CDMA radio signals by cell sites, thereby
                              reducing interference.
SMART ANTENNA...............  A system that can respond to changes in the radio frequency
                              environment through the use of software algorithms that
                              control an integrated antenna array.
SMR (SPECIALIZED MOBILE       A two-way radio telephony service making use of macrocells
 RADIO).....................  that cover an area up to 50 miles in diameter. Widely used
                              in dispatch operations by truck and taxi fleets. SMR systems
                              have much less radio spectrum than cellular systems, but
                              have a much greater range.
SPATIAL DIVERSITY...........  An antenna configuration of two or more elements that are
                              physically spaced (spatially diverse) to combat signal
                              fading and improve signal quality. The desired spacing
                              depends on the frequency band and the RF environment.
SPECTRUM....................  A continuous range of frequencies, ranging from 30 Hz to
                              3000 GHz, available for radio transmission and reception.
                              The FCC has set aside fixed portions of the spectrum for
                              cellular service, PCS service, television, FM radio, and
                              satellite transmissions.
SPECTRUM ALLOCATION.........  Federal government designation of a range of frequencies for
                              a category of use or uses.
SPECTRUM MANAGEMENT.........  A way to improve a network's capacity, coverage, and call
                              quality by using hardware and software tools for network
                              configuration and RF enhancement.
SUBSCRIBER..................  A customer of a wireless service provider or other
                              communications company.
SWITCH......................  See MTSO.

                              which a large number of users can access, in sequence, a
                              single radio frequency channel without interference because
                              each user is allocated a unique time slot within each
                              frequency channel.
TRANSCEIVER.................  Equipment that both receives and transmits radio waves.
TRANSMITTER.................  A device that generates signals.
TRUNKING....................  Allowing a subscriber unit to be connected to any unused
                              channel in a group of channels for an incoming or outgoing
                              call. Trunking efficiency is increased whenever greater
                              numbers of channels can be made available to any group of
                              subscribers at a given location and time.
WIRELESS....................  Describing a type of technology using radio-based systems
                              that allows transmission of voice and data signals through
                              radio frequencies without a physical connection.
WLL (WIRELESS LOCAL LOOP)...  A type of wireless technology which is used to provide
                              subscribers with standard telephone service. Eliminates the
                              need for a wire, or loop, connecting users to the PSTN by
                              transmitting voice communications over radio waves between
                              the end user and a base station that is connected to the
                              network equipment.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Metawave Communications Corporation
 
  We have audited the accompanying balance sheets of Metawave Communications
Corporation as of December 31, 1996 and 1997 and the related statements of
operations, stockholders' equity (deficit), and cash flows for the years then
ended and the period from January 19, 1995 (inception) to December 31, 1995.
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 Metawave Communications
Corporation at December 31, 1996 and 1997, and the results of its operations
and its cash flows for the years then ended and the period from January 19,
1995 (inception) to December 31, 1995, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                 (INFORMATION AS OF JUNE 30, 1998 AND FOR THE
             SIX MONTHS ENDED JUNE 30, 1997 AND 1998 IS UNAUDITED)
 
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
 Description of Business
 
  Metawave designs, develops, manufactures and markets spectrum management
solutions for the wireless communications industry. Metawave's spectrum
management solutions, consisting of smart antenna systems, applications
software and engineering services, enable cellular network operators to
increase overall network capacity, reduce network operation costs, better
manage network infrastructure and stimulate end user demand through improved
system quality. Using its proprietary technologies, the Company has developed
products that address the capacity, coverage, and call quality problems faced
by cellular network operators.
 
  The Company was incorporated in January 1995. Net revenue since inception
has been attributable to an engineering consulting contract in 1996, services
rendered by the Company's Network Services division during 1997 and sales of
the SpotLight 2000 system during the six months ended June 30, 1998. The
Company's Network Services division was discontinued during the first quarter
of 1998. Since inception, the Company has incurred significant losses and as
of June 30, 1998, had an accumulated deficit of $50.1 million.
 
 Unaudited Interim Financial Information
 
  The financial information as of June 30, 1998 and for the periods ended June
30, 1997 and 1998 is unaudited, but includes all adjustments (consisting only
of normal recurring adjustments) that the Company considers necessary for a
fair presentation of the financial position at such dates and the operations
and cash flows for the periods then ended. Operating results for the period
ended June 30, 1998 are not necessarily indicative of results that may be
expected for the entire year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates.
Significant estimates made in preparing the financial statements include the
allowance for doubtful accounts, inventory reserves and warranty accruals.
 
 Revenue Recognition
 
  Product revenues are recognized when the product has been shipped and all
customer acceptance conditions have been satisfied. Service revenues,
generally installation and consulting, are recognized when the services have
been performed. Revenue from maintenance contracts is deferred and recognized
ratably over the term of the agreement (which is typically one year). Any
billings in excess of revenue are classified as deferred revenue and projects
in process are recorded as inventory.
 
 Inventories
 
  Inventories are stated at the lower of cost (first-in, first-out) or market.
 
 Property and Equipment
 
  Property and equipment and leasehold improvements are recorded at cost.
Depreciation is provided on the straight-line method for financial statement
purposes and on accelerated methods for federal income tax purposes over
estimated useful lives of two to seven years. Leasehold improvements are
amortized over the lesser of the lease term or estimated useful life.
 
 Pro Forma Net Loss per Share
 
  Pro forma net loss per share is computed using the weighted average number
of shares of common stock outstanding and the weighted average convertible and
redeemable preferred stock outstanding as if such shares were converted to
common stock at the time of issuance. Common stock equivalents,

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
                 (INFORMATION AS OF JUNE 30, 1998 AND FOR THE
             SIX MONTHS ENDED JUNE 30, 1997 AND 1998 IS UNAUDITED)
 
1. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
including stock options and warrants, are excluded from the computation as t
heir effect is antidilutive. For the periods presented, there is no difference
between the basic and diluted earnings per share. Historical basic and diluted
earnings per share are not presented because they are considered meaningless
due to the significant change in capital structure upon the mandatory
conversion of convertible redeemable preferred stock upon completion of the
initial public offering.
 
 Warranty
 
  The Company provides a 12 to 18 month warranty which may vary depending upon
specific contractual terms, on all products and records a related provision
for estimated warranty costs at the date of sale.
 
 Advertising Costs
 
  Advertising costs are charged to expense as incurred. The Company had no
material advertising expense for the periods ended December 31, 1995 and 1996,
while $535,000 and $342,000 were recorded for the year ended December 31, 1997
and the six months ended June 30, 1998, respectively
 
 Cash Equivalents, Fair Values of Financial Instruments, and Concentration of
Credit Risk
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of cash equivalents, and trade receivables.
The carrying value of financial instruments approximates market value.
 
  Cash equivalents consist of investments with maturities of three months or
less when purchased. The Company invests with various high-quality
institutions and, by policy, limits the amount of credit exposure to any one
institution.
 
  The Company sells its products and provides services to customers in the
wireless communications industry. The Company performs on-going credit
evaluations of its customers' financial condition and generally does not
require collateral. The Company maintains reserves for potential credit
losses, and such losses have been within management's expectations and have
not been material in any year.
 
 Stock-Based Compensation
 
  The Company has adopted the disclosure-only provisions of Financial
Accounting Standards Board Statement No. 123 and applies Accounting Principles
Board Opinion No. 25 and related interpretations in accounting for its stock
option plans. Accordingly, the Company's stock-based compensation expense is
recognized based on the intrinsic value of the option on the date of grant.
Recognition of stock-based compensation expense under Statement 123 requires
the use of a fair value method to value stock options using option valuation
models that were developed for purposes other than valuing employee stock
options. Pro forma disclosure of net loss under Statement 123 is provided in
Note 6.

 Recently Issued Accounting Standards
 
  In 1997, the following accounting standards were issued: SFAS No. 129,
"Disclosure of Information About Capital Structure" requiring supplemental
disclosure of capital structure, SFAS No. 130, "Reporting Comprehensive
Income," (This statement establishes standards for reporting and disclosure of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements), SFAS No. 131,
"Disclosures About Segments of an Enterprise and Required Information," and
SOP 97-2, "Software Revenue Recognition." Each of these standards became
effective for the Company on January 1, 1998. The adoption of these standards
did not impact the Company's financial statements or disclosures.
 
  In March 1998, the AICPA issued SOP 98-1, Accounting For the Costs of
Computer Software Developed For or Obtained For Internal-Use. The SOP is
effective for the Company beginning on January 1, 1999 but earlier adoption is
encouraged. The SOP requires the capitalization of certain costs incurred
after the date of adoption in connection with developing or obtaining software
for internal-use. The Company elected to adopt the SOP in 1998. The SOP did
not have a material impact on the Company's operations or financial position.

  Notes payable are secured by equipment and vehicles.
 
  Future principal payments on notes payable at December 31, 1997 are as
follows: 1998--$139,439; 1999--$159,926; 2000--$84,929; 2001--$16,202; and
2002--$2,071.
 
  The Company has a credit facility with a commercial bank, which provides for
a revolving credit line of $7.5 million to support working capital with a $3.0
million sublimit for issuance of trade-related commercial and standby letters
of credit, which matures on October 14, 1999. Outstanding balances on the
credit line bear interest at the bank's prime rate (8.5%) as of December 31,
1997 and June 30, 1998, respectively, and are secured by the Company's
accounts receivable and inventory. At December 31, 1997 and June 30, 1998, no
amounts were outstanding under this revolving credit line secured by accounts
receivable and $2.5 million was outstanding related to issuance of a standby
letter of credit.
 
  On April 28, 1998, the Company issued $29 million of Senior Secured Bridge
Notes (Notes), which mature on April 28, 2000. The Notes accrue interest at
13.75%, payable semi-annually at the option of the Company in either
additional Notes or cash. Until the Notes are repaid in full, the interest
rate will increase by 200 basis points up to a maximum of 18.0%. On April 28,
1999 and at the end of each subsequent six-month period; to a maximum rate of
18.00%. One-half of the outstanding Notes and any accrued and unpaid interest
is due upon the occurrence of an Initial Public Offering (IPO). The other one-
half of the Notes may be redeemed at any time, prior to the maturity date, by
the Company by payment in cash of the principal and accrued interest.
 
  The Notes are secured by personal property and intellectual property of the
Company. The Company is required to comply with certain covenants and certain
reporting requirements determined by the noteholders.
 
  In connection with the Senior Secured Bridge financing, the noteholders
received warrants to purchase 537,500 shares of series D Preferred Stock at
$.01 per share. The Company recorded debt

issuance fees of approximately $5,820,000 related to the issuance of these
warrants. The fees are amortized over the two-year contractual life of the
Notes. The warrants have a two-year term. On April 28, 1999 and at the end of
each subsequent three-month period, the Company will issue the noteholders
200,000 additional warrants. This provision will terminate upon an IPO by the
Company and redemption of at least one-half of the issued and outstanding
Notes.
 
  The Company may redeem the balance of the Notes and warrants on or before
the completion of an IPO or on April 28, 1999 for and aggregate redemption and
repurchase price of $40.6 million.

Stock (Series A) through a private offering. Proceeds from the financing
amounted to $5,500,000.
 
  In May 1996, the Company issued 2,711,113 shares of Series B Preferred Stock
(Series B) through a private offering. Proceeds from the financing amounted to
$9,150,006. An additional 29,630 shares of Series B were issued in November
1996 with proceeds of $100,002.

  Holders of Series A, B, C, and D have preferential rights to dividends
($.08, $.27, $.49, and $.64 per share per annum, respectively) when and if
declared by the Board of Directors. Dividends are not cumulative until July
1999. The holders are entitled to the number of votes equal to the number of
shares of common stock into which the preferred stock could be converted. Each
share of preferred stock is convertible into one share of common stock at the
option of the holder, or automatically upon the vote or written consent of the
holders of the majority of the shares of Series A, B, C, and D originally
issued or upon the closing of an initial public offering of the Company's
common stock from which the aggregate proceeds are not less than $15 million.
The conversion rate is subject to adjustment, as provided by the Company's
Amended and Restated Articles of Incorporation. In the event of liquidation,
the holders of Series A, B, C, and D have preferential rights to liquidation
payments of $1.00, $3.375, $6.16, and $8.00 per share, respectively, plus any
declared but unpaid dividends. The preferred stock has redemption rights for a
six-month period beginning on December 31, 2000 upon the election of at least
50% of the holders. The redemption price is equal to the original purchase
price plus any declared but unpaid dividends.
 
 Convertible and Redeemable Preferred Stock Warrants
 
  In connection with a Master Lease Agreement dated December 13, 1995, the
Company has issued two warrants providing for the purchase of 48,750 shares

Warrant Agreements expire after seven years or eighteen months to three years
from the effective date of an initial public offering, whichever comes later.

6. STOCKHOLDERS' EQUITY
 
  Authorized Shares
 
  In anticipation of the IPO of the Company's Common Stock, in May 1998, the
Board of Directors approved the amendment and restatement of the Certificate
of Incorporation to change the authorized number of shares of preferred stock
to 15,000,000 shares and increase the number of authorized shares of Common
Stock of the Company to 150,000,000 shares. These changes are to take effect
upon completion of the IPO.
 
  Stock Repurchase Agreement
 
  Prior to June 30, 1998, the Company had common stock repurchase agreements
with two founders, whereby if the shareholder ceases to be an employee of the
Company, the Company has the right to repurchase shares of common stock at the
original issuance price paid by the founder. The stock held by the founders,
and subject to the terms of these agreements, vested during each full fiscal
quarter commencing after June 30, 1995 at a rate of 33% per year and became
fully vested on June 30, 1998. As of December 31, 1997, there were 344,437
shares subject to repurchase with an aggregate purchase price of $1,240.
During 1996, one of the founders surrendered 100,000 shares to the Company for
no consideration. On January 10, 1998, the Company repurchased 137,775 shares
of common stock from one of the founders for $501.
 
 Proforma Stockholders' Equity (Unaudited)
 
  The proforma stockholders' equity in the accompanying balance sheet reflects
the conversion of convertible and redeemable Preferred Stock and the
conversion of Preferred Stock warrants to Common Stock warrants coincident
with the IPO.
 
  Stock Option Plan
 
  The Company's 1995 Stock Option Plan (the Plan) provides for the granting of
incentive stock options and nonqualified stock options to employees, officers,
directors, and consultants. Options under the Plan have been granted at fair
market value on the date of grant and expire between five and ten years.
Options granted under this Plan generally become exercisable at the rate of
25% of the total number of shares subject to the option after the first
anniversary following the date of grant, with 2.083% vesting monthly
thereafter, with all shares becoming fully vested on the fourth anniversary
date of the date of grant. The Company has reserved 4,150,000 shares of common
stock for issuance under the Plan.
 
  In anticipation of an IPO of the Company's common stock, in May 1998, the
Board of Directors approved the 1998 Stock Option Plan and the 1998 Employees
Stock Purchase Plan, subject to stockholder approval. Shares reserved for
issuance under these plans were 850,000 shares and 500,000 shares,
respectively.
 
  The 1998 Directors' Stock Option Plan was adopted by the Board of Directors
in February 1998 and approved by the stockholders on April 20, 1998. A total
of 300,000 shares of Common Stock has been

reserved for issuance under the Directors' Plan. The Directors' Plan provides
for the automatic grant of nonstatutory stock options to nonemployee directors
of the Company upon joining the Board or upon the effectiveness of the
Company's initial public offering. Provided an individual remains a director,
the Directors' Plan provides that each option granted under the Plan shall
become exercisable in installments cumulatively as to 25% of the total number
of shares subject to the option on the first anniversary of the date of grant
of the option and 2.083% of the total number of shares subject to the option
each month thereafter. 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. The fair market
value of any option granted concurrently with the initial effectiveness of the
Purchase Plan shall be the Price to Public set forth in the final prospectus
relating to this Offering. Options granted under the Directors' Plan have a
term of ten years.
 
  In 1997, deferred compensation of $1,881,382 was recorded for options
granted under the 1995 Plan. The deferred compensation was calculated as the
difference between the exercise price and the deemed value of the Company's
stock options granted under the 1995 Plan. The deferred compensation is
amortized over the vesting period of the related options. Amortized stock
compensation of $676,491 and $328,000 was recorded in the year ended December
31,1997 and the six months ended June 30, 1998, respectively.
 
  Had the stock compensation expense for the Company's stock option plan been
determined based on the estimated fair value using the minimum value option
pricing model at the date of grant, the Company's net loss would have been
increased to these pro forma amounts (in thousands, except per share data):

     Pro forma...................................      --        --      (1.54)
</TABLE>
 
  The fair value for these options was estimated at the date of grant using
minimum value option pricing models that take into account: (1) the stock
price at the grant date, (2) the exercise prices, (3) a one-year expected life
beyond the vest date, (4) no dividends, and (5) a risk-free interest rate of
between 5.42% and 6.43% during 1995 through 1997 over the expected life of the
options. Compensation expense recognized in providing pro forma disclosures
may not be representative of the effects on pro forma net income for future
years because the amounts above include only the amortization for the fair
value of 1997, 1996, and 1995 grants.

7. INCOME TAXES
 
  As of December 31, 1997, the Company had federal net operating loss
carryforwards (NOL) of approximately $28.5 million and research and
development tax credit carryforwards of approximately $677,500. The federal
net operating loss carryforwards will begin to expire in the year 2009 if not
utilized. As a result of changes in ownership coincident with the recent
financings, the utilization of a portion of the net operating loss
carryforward will be limited, pursuant to Section 382 of the Internal Revenue
Code of 1986, as amended. Approximately $9,200,000 of the NOL is limited to
$920,000 per year. The remaining NOL is not subject to limitation as of
December 31, 1997, but is estimated to be subject to annual limitation of
$8,000,000 upon completion of the IPO.

7. INCOME TAXES (CONTINUED)
 
  Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. The Company has
recognized a valuation allowance equal to the deferred tax assets due to the
uncertainty of realizing the benefits of the assets. Significant components of
the Company's deferred tax liabilities and assets as of December 31 are as

8. COMMITMENTS
 
  The Company has entered into capital lease agreements to acquire certain
furniture and equipment, with lease terms ranging from 36 to 48 months. The
furniture and equipment, which serves as collateral for the leases, was
recorded at $4,635,553 and had accumulated amortization of $1,639,816 at
December 31, 1997. Amortization of the assets was included in depreciation
expense.
 
  Operating leases are for office and manufacturing facilities.
 
  In September 1997, the Company entered into a build-to-suit lease
arrangement for 95,838 square feet that will replace the current facilities.
The Company occupied the new building in June 1998, at which time the lease
commenced, and expires May 31, 2005. The Company, at its option, may extend
the term of this lease for two successive periods of five years each. The
option must be elected twelve months prior to the expiration of the initial
lease term. In connection with this arrangement, the Company has issued
letters of credit to the landlord aggregating $2.5 million.

  Rental expense for operating leases was $667,939, $304,619, and $21,167 for
the years ended December 31, 1997, 1996, and 1995, respectively.
 
  The Company entered into agreements with certain leasing companies to
provide up to $2 million in 1996, $3 million in 1997 and $3.5 million at June
30, 1998 of financing to allow the Company to lease additional equipment.
Pursuant to these agreements, equipment leases would generally have a term of
three years and an implicit interest rate of 8.756% for 1996, 7.25% in 1997
and 14.5% at June 30, 1998 all are secured by the underlying equipment. The
Company issued warrants to purchase 4,375 shares of series D Preferred Stock
with an exercise price of $8 per share in conjunction with one of the lease
agreements.
 
9. RETIREMENT PLANS
 
  The Company has a salary deferral 401(k) plan for its employees. The plan
allows employees to contribute a percentage of their pretax earnings annually,
subject to limitations imposed by the Internal Revenue Service. The plan also
allows the Company to make a matching contribution, subject to certain
limitations. To date, the Company has made no contributions.
 
10. RELATED-PARTY TRANSACTIONS
 
  In October 1997, the Board authorized a secured loan of $162,500 and an
unsecured loan of $75,000 to the Company's Chief Financial Officer. Both loans
bear interest at 5.5%. The secured loan is payable in full on October 28, 2002
or earlier based upon certain events specified in the agreement. The unsecured
loan is forgiven over three years, with the remaining balance of $25,000 due
on October 22, 2000 or earlier based upon termination of employment.

11. REVENUES AND OPERATIONS
 
  The Company's customers are primarily cellular network operators in the
United States and certain international markets. As such, the Company's
primary market is made up of a limited number of customers operating within
the same industry, thereby subjecting the Company to business risks associated
with potential downturns of the industry. During 1997, two customers of the
Network Services division represented 63% and 27% of total revenue.
 
  In addition, the Company's current product design includes two key
components that are each currently supplied by a single supplier. Purchases
from these key suppliers aggregated $2,046,975 and $1,565,086 during 1997.
 
  In December 1997, the Company determined that it would discontinue the
Network Services division. Accordingly, the carrying value of these fixed
assets has been adjusted to estimated recoverable value, thereby resulting in
an impairment loss of $200,000, which is included in other expenses in the
accompanying 1997 Statement of Operations.
 
  In June 1998, in connection with certain patent licenses, the Company issued
warrants and recorded fees for an aggregate amount of $360,000. This amount
was appropriately recorded as an operating expense for the period ended June
30, 1998.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the DGCL 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 "Securities Act"). Article IX of
the Registrant's Amended and Restated Certificate of Incorporation (Exhibit
3.1 hereto) provides for indemnification of its directors and officers to the
maximum extent permitted by the DGCL and Article IX of the Registrant's Bylaws
(Exhibit 3.2 hereto) provides for indemnification of its directors, officers,
employees and other agents to the maximum extent permitted by the DGCL. In
addition, the Registrant has entered into Indemnification Agreements (Exhibit
10.1 hereto) with its directors and officers containing provisions which are
in some respects broader than the specific indemnification provisions
contained in the DGCL. The indemnification agreements may require the Company,
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 8 of the Underwriting
Agreement contained in Exhibit 1.1 hereto, indemnifying officers and directors
of the Company against certain liabilities.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES
 
  (a) Since January 1, 1995, the Registrant has issued and sold (without
payment of any selling commission to any person) the following unregistered

  1996, a warrant to purchase shares of Series B Preferred Stock convertible
  into 19,999 shares of Common Stock for an aggregate purchase price of
  $95,295; and (D) in June 1997, a warrant to purchase shares of Series C
  Preferred Stock convertible into 34,091 shares of Common Stock for an
  aggregate purchase price of $210,001.
 
    (6) In April 1998, the Registrant issued an aggregate principal amount of
  $29.0 million 13.75% Senior Secured Bridge Notes due April 28, 2000 to
  certain institutional investors. In connection with the issuance of such
  notes, the Registrant issued warrants to purchase shares of Series D
  Preferred Stock convertible into 537,500 shares of Common Stock for an
  aggregate purchase price of $5,375.
 
    (7) In April 1998, the Registrant issued to an equipment lease provider a

  Stock for an aggregate purchase price of $110.
 
    (9) As of June 30, 1998, an aggregate of 511,601 shares of Common Stock

  (b) There were no underwritten offerings employed in connection with any of
the transactions set forth in Item 15(a).
 
  The issuances described in Items 15(a)(1) through 15(a)(8) were deemed to be
exempt from registration under the Securities Act in reliance upon Section
4(2) thereof as transactions by an issuer not involving any public offering.
The recipients of securities in each such transaction represented their
intentions to acquire the securities for investment only and not with a view
to or for sale in connection with any distribution thereof and appropriate
legends where affixed to the securities issued in such transactions. All
recipients had adequate access, through their relationships with the Company,
to information about the Registrant. The issuances described in Items 15(a)(9)
were deemed to be exempt from registration under the Securities Act in
reliance upon Rule 701 promulgated thereunder in that they were offered and
sold either pursuant to written compensatory benefit plans or pursuant to a
written contract relating to compensation, as provided by Rule 701. In
addition, such issuances were deemed to be exempt from registration under
Section 4(2) of the Securities Act as transactions by an issuer not involving
any public offering.

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
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.

Merrill Lynch, Pierce, Fenner & Smith Incorporated
NationsBanc Montgomery Securities LLC
  As Representatives of the Several Underwriters
c/o BT Alex. Brown Incorporated
135 East Baltimore Street
Baltimore, Maryland 21202

Gentlemen:

     Metawave Communications Corporation, a Delaware corporation (the
"Company"), proposes to sell to the several underwriters named in Schedule I
hereto (the "Underwriters") for whom you are acting as representatives (the
"Representatives") an aggregate of 5,000,000 shares of the Company's Common
Stock, $0.0001 par value (the "Firm Shares").  The respective amounts of the
Firm Shares to be so purchased by the several Underwriters are set forth
opposite their names in Schedule I hereto.  The Company also proposes to sell at
the Underwriters' option an aggregate of up to 750,000 additional shares of
the Company's Common Stock (the "Option Shares") as set forth below.

     As the Representatives, you have advised the Company (a) that you are
authorized to enter into this Agreement on behalf of the several Underwriters
and to act on their behalf in the manner herein provided and (b) that the
several Underwriters are willing, acting severally and not jointly, to purchase
the numbers of Firm Shares set forth opposite their respective names in Schedule
I, plus their pro rata portion of the Option Shares if you elect to exercise the
over-allotment option in whole 
<PAGE>
 
or in part for the accounts of the several Underwriters. The Firm Shares and the
Option Shares (to the extent the aforementioned option is exercised) are herein
collectively called the "Shares."

     In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

     1.   Representations and Warranties of the Company.

          The Company represents and warrants to each of the Underwriters as
follows:

          (a) A registration statement on Form S-1 (File No. 333-______) with
respect to the Shares has been prepared by the Company in conformity in all
material respects with the requirements of the Securities Act of 1933, as
amended (the "Act"), and the Rules and Regulations (the "Rules and Regulations")
of the Securities and Exchange Commission (the "Commission") thereunder and has
been filed with the Commission.  Copies of such registration statement,
including any amendments thereto, the preliminary prospectuses (meeting the
requirements of the Rules and Regulations) contained therein and the exhibits,
financial statements and schedules, as finally amended and revised, have
heretofore been delivered by the Company to you.  Such registration statement,
together with any registration statement filed by the Company pursuant to Rule
462 (b) of the Act, herein referred to as the "Registration Statement," which
shall be deemed to include all information omitted therefrom in reliance upon
Rule 430A and contained in the Prospectus referred to below, has become
effective under the Act and no post-effective amendment to the Registration
Statement has been filed as of the date of this Agreement.  "Prospectus" means
(a) the form of prospectus first filed with the Commission pursuant to Rule
424(b) or (b) the last preliminary prospectus included in the Registration
Statement filed prior to the time it becomes effective or filed pursuant to Rule
424(a) under the Act that is delivered by the Company to the Underwriters for
delivery to purchasers of the Shares, together with the term sheet or
abbreviated term sheet filed with the Commission pursuant to Rule 424(b)(7)
under the Act.  Each preliminary prospectus included in the Registration
Statement prior to the time it becomes effective is herein referred to as a
"Preliminary Prospectus." Any reference herein to the Registration Statement,
any Preliminary Prospectus or to the Prospectus shall be deemed to refer to and
include any supplements or amendments to any Prospectus, filed with the
Commission after the date of filing of the Prospectus under Rules 424(b) or
430A, and prior to the termination of the offering of the Shares by the
Underwriters.

          (b) The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the State of Delaware, with
corporate power and authority to own or lease its properties and conduct its
business as described in the Registration Statement.  The Company is duly
qualified to transact business in all jurisdictions in which the conduct of
their business requires such qualification except where the failure to so
qualify would not have a material adverse effect on the business, properties,
assets, rights, operations, financial condition or results of operation of the
Company. The Company has no subsidiaries and owns no 

                                       3
<PAGE>
 
shares of stock or any other equity securities of any corporation or have any
equity interest in any firm, partnership, association or entity.

          (c) The outstanding shares of Common Stock of the Company have been
duly authorized and validly issued and are fully paid and non-assessable; the
Shares to be issued and sold by the Company have been duly authorized and when
issued and paid for as contemplated herein will be validly issued, fully paid
and non-assessable; and no preemptive rights of stockholders exist with respect
to any of the Shares or the issue and sale thereof.  Neither the filing of the
Registration Statement nor the offering or sale of the Shares as contemplated by
this Agreement gives rise to any rights, other than those which have been waived
or satisfied, for or relating to the registration of any shares of Common Stock.

          (d) The information set forth under the caption "Capitalization" in
the Prospectus is true and correct.  All of the Shares conform to the
description set forth in "Description of Securities" in the Prospectus, insofar
as it purports to constitute a summary of the Shares.  The form of certificates
for the Shares conforms to the corporate law of the jurisdiction of the
Company's incorporation.

          (e) The Commission has not issued an order preventing or suspending
the use of any Prospectus relating to the proposed offering of the Shares nor
instituted proceedings for that purpose.  The Registration Statement contains,
and the Prospectus and any amendments or supplements thereto will contain, all
statements which are required to be stated therein by, and will conform in all
material respects, to the requirements of the Act and the Rules and Regulations.
The Registration Statement and any amendment thereto do not contain, and will
not contain, any untrue statement of a material fact and do not omit, and will
not omit, to state any material fact required to be stated therein or necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.  The Prospectus and any amendments and
supplements thereto do not contain, and will not contain, any untrue statement
of material fact; and do not omit, and will not omit, to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading;
provided, however, that the Company makes no representations or warranties as to
information contained in or omitted from the Registration Statement or the
Prospectus, or any such amendment or supplement, in reliance upon, and in
conformity with, written information furnished to the Company by or on behalf of
any Underwriter through the Representatives, specifically for use in the
preparation thereof.

          (f) The financial statements of the Company, together with related
notes and schedules as set forth in the Registration Statement, present fairly
the financial position and the results of operations and cash flows of the
Company and the consolidated Subsidiaries, at the indicated dates and for the
indicated periods.  Such financial statements and related schedules have been
prepared in accordance with generally accepted principles of accounting,
consistently applied throughout the periods involved, except as disclosed
herein, and all adjustments necessary for a fair presentation of results for
such periods have been made.  The summary financial and statistical data

                                       4
<PAGE>
 
included in the Registration Statement presents fairly the information shown
therein and such data has been compiled on a basis consistent with the financial
statements presented therein and the books and records of the Company.  [The pro
forma financial information included in the Registration Statement and the
Prospectus present fairly the information shown therein, have been prepared in
accordance with the Commission's rules and guidelines with respect to pro forma
financial statements, have been properly compiled on the pro forma bases
described therein, and, in the opinion of the Company, the assumptions used in
the preparation thereof are reasonable and the adjustments used therein are
appropriate to give effect to the transactions or circumstances referred to
therein.]

          (g) Ernst & Young LLP, who have expressed their opinion with respect
to the financial statements filed with the Commission as part of the
Registration Statement, are independent public accountants as required by the
Act and the Rules and Regulations.

          (h) There is no action, suit, claim or proceeding pending or, to the
knowledge of the Company, threatened against the Company before any court or
administrative agency or otherwise which if determined adversely to the Company
might result in any material adverse change in the earnings, business,
management, properties, assets, rights, operations, financial condition or
prospects of the Company or to prevent the consummation of the transactions
contemplated hereby, except as set forth in the Registration Statement.

          (i) The Company has good and marketable title to all of the properties
and assets reflected in the financial statements (or as described in the
Registration Statement) hereinabove described, subject to no lien, mortgage,
pledge, charge or encumbrance of any kind except those reflected in such
financial statements (or as described in the Registration Statement) or which
are not material in amount.  The Company occupies its leased properties under
valid and binding leases conforming in all material respects to the description
thereof set forth in the Registration Statement.

          (j) The Company has filed all Federal, State, local and foreign income
tax returns which have been required to be filed and has paid all taxes
indicated by said returns and all assessments received by them or any of them to
the extent that such taxes have become due.  All tax liabilities have been
adequately provided for in the financial statements of the Company.

          (k) Since the respective dates as of which information is given in the
Registration Statement, as it may be amended or supplemented, there has not been
any material adverse change or any development involving a prospective material
adverse change in or affecting the earnings, business, management, properties,
assets, rights, operations, financial condition or prospects of the Company,
whether or not occurring in the ordinary course of business, and there has not
been any material transaction entered into or any material transaction that is
probable of being entered into by the Company, other than transactions in the
ordinary course of business and changes and transactions described in the
Registration Statement, as it may be amended 

                                       5
<PAGE>
 
or supplemented. The Company has no material contingent obligations which are
not disclosed in the Company's financial statements which are included in the
Registration Statement.

          (l) The Company is not nor with the giving of notice or lapse of time
or both, will be, in violation of or in default under its Certificate of
Incorporation or Bylaws or under any agreement, lease, contract, indenture or
other instrument or obligation to which it is a party or by which it, or any of
its properties, is bound and which default is of material significance in
respect of the financial condition of the Company or the business, management,
properties, assets, rights, operations, financial condition or prospects of the
Company.  The execution and delivery of this Agreement and the consummation of
the transactions herein contemplated and the fulfillment of the terms hereof
will not conflict with or result in a breach of any of the terms or provisions
of, or constitute a default under, any indenture, mortgage, deed of trust or
other agreement or instrument to which the Company, or of the Certificate of
Incorporation or Bylaws of the Company or any order, rule or regulation
applicable to the Company of any court or of any regulatory body or
administrative agency or other governmental body; except where such conflict,
breach, violation or default would not have a material adverse effect on the
Company's business, management, properties, assets, rights, operations,
financial condition or prospects of the Company.

          (m) Each approval, consent, order, authorization, designation,
declaration or filing by or with any regulatory, administrative or other
governmental body necessary in connection with the execution and delivery by the
Company of this Agreement and the consummation of the transactions herein
contemplated (except such additional steps as may be required by the Commission,
the National Association of Securities Dealers, Inc. (the "NASD") or such
additional steps as may be necessary to qualify the Shares for public offering
by the Underwriters under state securities or Blue Sky laws) has been obtained
or made and is in full force and effect.

          (n) The Company owns or possesses sufficient licenses or other rights
to use all patents, copyrights, trade secrets, trademarks, service marks, trade
names, technology, know-how or other proprietary information or materials
necessary to the conduct of the business now being conducted by the Company as
described in the Prospectus.  The Company holds all material licenses,
certificates and permits from governmental authorities which are necessary to
the conduct of its business.  The Company knows of no material infringement by
others of patents, patent rights, trade names, trademarks or copyrights owned by
or licensed to the Company.  Except as specifically disclosed in the Prospectus,

trademarks, trade names, patent rights, mask works, copyrights, licenses,
approvals and governmental authorizations to conduct its business as now
conducted and as proposed to be conducted; and the Company has no knowledge of
any infringement by it of any trademark, trade name, patent right, mask work,
copyright, license, trade secret or other similar right of others, and, to the
Company's knowledge, except as disclosed in the Prospectus, no claim has been
made against the Company regarding trademark, trade name, patent, mask work,
copyright, license, trade secret or other infringement which could have a
material 

                                       6
<PAGE>
 
adverse effect on the financial condition, business or results of operations of
the Company.

          (o) Neither the Company, nor to the Company's best knowledge, any of
its affiliates, has taken or may take, directly or indirectly, any action
designed to cause or result in, or which has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of the shares of Common Stock to facilitate the sale or resale of the
Shares.
          (p) The Company is not an "investment company" within the meaning of
such term under the Investment Company Act of 1940 and the rules and regulations
of the Commission thereunder.

          (q) The Company maintains a system of internal accounting controls

business and the value of their respective properties.

          (s) The Company is in compliance in all material respects with all
presently applicable provisions of the Employee Retirement Income Security Act
of 1974, as amended, including the regulations and published interpretations
thereunder ("ERISA"); no "reportable event" (as defined in ERISA) has occurred
with respect to any "pension plan" (as defined in ERISA) for which the Company
would have any liability; the Company has not incurred and does not expect to
incur liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the Internal
Revenue Code of 1986, as amended, including the regulations and published
interpretations thereunder (the "Code"); and each "pension plan" for which the
Company would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all material respects and nothing has
occurred, whether by action or by failure to act, which would cause the loss of
such qualification.

          (t) The Company confirms as of the date hereof that it is in
compliance with all provisions of Section 

                                       7

          (u) The Company is conducting its business in compliance with all
applicable laws, rules and regulations of the jurisdictions in which it is
conducting business, including, without limitation all applicable rules and
regulations of the Federal Communications Commission and all applicable local,

so in compliance could not materially adversely affect the financial condition,
business or results of operations of the Company.

     2.   Purchase, Sale and Delivery of the Firm Shares.

          (a) On the basis of the representations, warranties and covenants
herein contained, and subject to the conditions herein set forth, the Company
agrees to sell to the Underwriters and each Underwriter agrees, severally and
not jointly, to purchase, at a price of $_____ per share, the number of Firm
Shares set forth opposite the name of each Underwriter in Schedule I hereof,
subject to adjustments in accordance with Section 10 hereof.

          (b) Payment for the Firm Shares to be sold hereunder is to be made in
New York Clearing House funds by certified or bank cashier's checks drawn to the
order of the Company against delivery of certificates therefor to the
Representatives for the several accounts of the Underwriters.  Such payment and
delivery are to be made at the offices of BT Alex. Brown Incorporated, 1 South
Street, Baltimore, Maryland, at 10:00 a.m., Baltimore time, on the third
business day after the date of this Agreement or at such other time and date not
later than five business days thereafter as you and the Company shall agree
upon, such time and date being herein referred to as the "Closing Date."  (As
used herein, "business day" means a day on which the New York Stock Exchange is
open for trading and on which banks in New York are open for business and are
not permitted by law or executive order to be closed.)  The certificates for the
Firm Shares will be delivered in such denominations and in such registrations as
the Representatives request in writing not later than the second full business
day prior to the Closing Date, and will be made available for inspection by the
Representatives at least one business day prior to the Closing Date.

          (c) In addition, on the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the
Company hereby grants an option to the several Underwriters to purchase the
Option Shares at the price per share as set forth in the first paragraph of this
Section 2.  The option granted hereby may be exercised in whole or in part by
giving written notice (i) at any time before the Closing Date and (ii) only once
thereafter within 30 days after the date of this Agreement, by you, as
Representatives of the several Underwriters, to 

                                       8
<PAGE>
 
the Company setting forth the number of Option Shares as to which the several
Underwriters are exercising the option, the names and denominations in which the
Option Shares are to be registered and the time and date at which such
certificates are to be delivered. The time and date at which certificates for
Option Shares are to be delivered shall be determined by the Representatives but
shall not be earlier than three nor later than 10 full business days after the
exercise of such option, nor in any event prior to the Closing Date (such time
and date being herein referred to as the "Option Closing Date"). If the date of
exercise of the option is three or more days before the Closing Date, the notice
of exercise shall set the Closing Date as the Option Closing Date. The number of
Option Shares to be purchased by each Underwriter shall be in the same
proportion to the total number of Option Shares being purchased as the number of
Firm Shares being purchased by such Underwriter bears to 5,000,000, adjusted by
you in such manner as to avoid fractional shares. The option with respect to the
Option Shares granted hereunder may be exercised only to cover over-allotments
in the sale of the Firm Shares by the Underwriters. You, as Representatives of
the several Underwriters, may cancel such option at any time prior to its
expiration by giving written notice of such cancellation to the Company. To the
extent, if any, that the option is exercised, payment for the Option Shares
shall be made on the Option Closing Date in New York Clearing House funds by
certified or bank cashier's check drawn to the order of the Company against
delivery of certificates therefor at the offices of BT Alex. Brown Incorporated,
1 South Street, Baltimore, Maryland.

          (d) The Company hereby confirms its engagement of Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("Merrill Lynch") as, and Merrill Lynch
hereby confirms its Agreement with the Company to render services as, a
"Qualified Independent Underwriter," within the meaning of Section (b)(15) of
Rule 2720 of the National Association of Securities Dealers, Inc. with respect
to the offering and sale of the Shares.  Merrill Lynch, solely in its capacity
has the Qualified Independent Underwriter and not otherwise, is referred to
herein as the "QIU."  The price at which the Shares will be sold to the public
shall not be greater than the maximum price recommended by the QIU.

     3.   Offering by the Underwriters.

          It is understood that the several Underwriters are to make a public
offering of the Firm Shares as soon as the Representatives deem it advisable to
do so.  The Firm Shares are to be initially offered to the public at the initial
public offering price set forth in the Prospectus.  The Representatives may from
time to time thereafter change the public offering price and other selling
terms.  To the extent, if at all, that any Option Shares are purchased pursuant
to Section 2 hereof, the Underwriters will offer them to the public on the
foregoing terms.

          It is further understood that you will act as the Representatives for
the Underwriters in the offering and sale of the Shares in accordance with a
Master Agreement Among Underwriters entered into by you and the several other
Underwriters.

                                       9

     4.   Covenants of the Company.

          The Company covenants and agrees with the several Underwriters that:

          (a) The Company will (i) use its best efforts to cause the
Registration Statement to become effective or, if the procedure in Rule 430A of
the Rules and Regulations is followed, to prepare and timely file with the
Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form
approved by the Representatives containing information previously omitted at the
time of effectiveness of the Registration Statement in reliance on Rule 430A of
the Rules and Regulations, (ii) not file any amendment to the Registration
Statement or supplement to the Prospectus of which the Representatives shall not
previously have been advised and furnished with a copy or to which the
Representatives shall have reasonably objected in writing or which is not in
compliance with the Rules and Regulations and (iii) file on a timely basis all
reports and any definitive proxy or information statements required to be filed
by the Company with the Commission subsequent to the date of the Prospectus and
prior to the termination of the offering of the Shares by the Underwriters.

          (b) The Company will advise the Representatives promptly (i) when the
Registration Statement or any post-effective amendment thereto shall have become
effective, (ii) of receipt of any comments from the Commission, (iii) of any
request of the Commission for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information, and (iv) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the use of the Prospectus or of the institution of any
proceedings for that purpose.  The Company will use its best efforts to prevent
the issuance of any such stop order preventing or suspending the use of the
Prospectus and to obtain as soon as possible the lifting thereof, if issued.

          (c) The Company will cooperate with the Representatives in endeavoring
to qualify the Shares for sale under the securities laws of such jurisdictions
as the Representatives may reasonably have designated in writing and will make
such applications, file such documents, and furnish such information as may be
reasonably required for that purpose, provided the Company shall not be required
to qualify as a foreign corporation or to file a general consent to service of
process in any jurisdiction where it is not now so qualified or required to file
such a consent.  The Company will, from time to time, prepare and file such
statements, reports, and other documents, as are or may be required to continue
such qualifications in effect for so long a period as the Representatives may
reasonably request for distribution of the Shares.

          (d) The Company will deliver to, or upon the order of, the
Representatives, from time to time, as many copies of any Preliminary Prospectus
as the Representatives may reasonably request.  The Company will deliver to, or
upon the order of, the Representatives during the period when delivery of a
Prospectus is required under the Act, as many copies of the Prospectus in final
form, or as thereafter amended or supplemented, as the Representatives may
reasonably request.  The Company will deliver to the Representatives at or
before the Closing Date, four signed copies of the 

                                       10
<PAGE>
 
Registration Statement and all amendments thereto including all exhibits filed
therewith, and will deliver to the Representatives such number of copies of the
Registration Statement (including such number of copies of the exhibits filed
therewith that may reasonably be requested), and of all amendments thereto, as
the Representatives may reasonably request.

          (e) The Company will comply with the Act and the Rules and
Regulations, and the Securities Exchange Act of 1934 (the "Exchange Act"), and
the rules and regulations of the Commission thereunder, so as to permit the
completion of the distribution of the Shares as contemplated in this Agreement
and the Prospectus.  If during the period in which a prospectus is required by
law to be delivered by an Underwriter or dealer, any event shall occur as a
result of which, in the judgment of the Company or in the reasonable opinion of
the Underwriters, it becomes necessary to amend or supplement the Prospectus in
order to make the statements therein, in the light of the circumstances existing
at the time the Prospectus is delivered to a purchaser, not misleading, or, if

          (l) The Company shall not invest, or otherwise use the proceeds

on the part of the Company to perform any undertaking or satisfy any condition
of this Agreement or to comply with any of the terms hereof on its part to be
performed, unless such failure to satisfy said condition or to comply with said

with respect to such documents and matters.

               (vii) Such counsel does not know of any contracts or documents

governmental body is necessary in connection with the execution and delivery of
this Agreement and the consummation of the transactions herein contemplated

as have been obtained or made, specifying the same.

               (xii) The Company is not, and will not become, as a result of the
consummation of the transactions contemplated by this Agreement, and application

          In rendering such opinion Venture Law Group, A Professional
Corporation, may rely as to matters governed by the laws of states other than
Delaware, Washington or Federal laws on local counsel in such jurisdictions,
provided that in each case Venture Law Group, A Professional Corporation, shall
state that they believe that they and the Underwriters are justified in relying
on such other counsel.  In addition to the matters set forth above, such opinion
shall also include a statement to the effect that, [ALTHOUGH SUCH COUNSEL DOES
NOT ASSUME ANY RESPONSIBILITY FOR THE ACCURACY, COMPLETENESS OR FAIRNESS OF THE
STATEMENTS CONTAINED IN THE REGISTRATION STATEMENT OR THE PROSPECTUS,] nothing
has come to the attention of such counsel which leads them to believe that (i)
the Registration Statement, at the time it became effective under the Act (but
after giving effect to any modifications incorporated therein pursuant to Rule
430A under the Act) and as of the Closing Date or the Option Closing Date, as
the case may be, contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and (ii) the Prospectus, or any supplement
thereto, on the date it was filed pursuant to the Rules and Regulations and as
of the Closing Date or the Option Closing Date, as the case may be, contained an
untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements, in the light of the circumstances
under which they are made, not misleading (except that such counsel need express
no view as to financial statements, related notes, schedules and other financial
information derived therefrom).  With respect to such statement, Venture Law
Group, A Professional Corporation may state that their belief is based upon the
procedures set forth therein, but is without independent check and verification.

          (c) The Underwriters shall have received on the Closing Date an
opinion of Fulbright & Jaworski LLP, dated the Closing Date, with respect to
certain intellectual property matters, to the effect that:

               (i) The Company owns all patents, trademarks, trademark
registrations, service marks, service mark registrations, trade names,
copyrights, licenses, inventions, trade secrets and rights described in the
Prospectus as being owned by it or necessary for the conduct of its business,
and such counsel is not aware of any claim to the contrary or any challenge by
any other person to the rights of the Company with respect to the foregoing
other than those identified in the Prospectus.

                                       16
<PAGE>
               (ii) Such counsel is not aware of any legal actions, claims or
proceedings pending or threatened against the Company alleging that the Company
is infringing or otherwise violating any patents or trade secrets owned by
others other than those identified in the Prospectus.
 
               (iii) Such counsel has reviewed the descriptions of patents and
patent applications under the captions "Risk Factors--Uncertainty Regarding
Protection of Intellectual Property" and "Business--Intellectual Property" in
the Registration Statement and Prospectus, and, to the extent they constitute
matters of law or legal conclusions, these descriptions are accurate and fairly
and completely present the patent situation of the Company.

               (iv) Such counsel is aware of nothing that causes such counsel to
believe that, as of the date that the Registration Statement became effective
and as of the date of such opinion, the description of patents and patent
applications under the captions "Risk Factors--Uncertainty Regarding Protection
of Intellectual Property" and "Business--Intellectual Property" in the
Registration Statement and Prospectus contained or contains any untrue statement
of a material fact or omitted or omits to state a material fact necessary to
make the statements made therein, in light of the circumstances under which they
were made, not misleading, including without limitation, any undisclosed
material issue with respect to the subsequent validity or enforceability of such
patent or patent issuing from any such pending patent application.

          (d) The Representatives shall have received from Wilson Sonsini
Goodrich & Rosati, P.C., counsel for the Underwriters, an opinion dated the
Closing Date or the Option Closing Date, as the case may be, substantially to
the effect specified in subparagraphs [(iv) and (v)] of Paragraph (b) of this
Section 6, and that the Company is a duly organized and validly existing
corporation under the laws of the State of Delaware.  In rendering such opinion
Wilson Sonsini Goodrich & Rosati, P.C. may rely as to all matters governed other
than by the laws of the State of California, the State of Delaware or Federal
laws on the opinion of counsel referred to in Paragraph (b) of this Section 6.
In addition to the matters set forth above, such opinion shall also include a
statement to the effect that nothing has come to the attention of such counsel
which leads them to believe that (i) the Registration Statement, or any
amendment thereto, as of the time it became effective under the Act (but after
giving effect to any modifications incorporated therein pursuant to Rule 430A
under the Act) and as of the Closing Date or the Option Closing Date, as the
case may be, contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and (ii) the Prospectus, or any supplement
thereto, on the date it was filed pursuant to the Rules and Regulations and as
of the Closing Date or the Option Closing Date, as the case may be, contained an

necessary in order to make the statements, in the light of the circumstances
under which they are made, not misleading (except that such counsel need express
no view as to financial statements, related notes, schedules and other financial
information therein).  With respect to such statement, Wilson Sonsini Goodrich &
Rosati, P.C. may state that their belief is based upon the procedures set forth
therein, but is without independent check and verification.

provided in this Section 8(c) if the party to whom notice was not given was
unaware of the proceeding to which such notice would have related and was
materially prejudiced by the failure to give such notice, but the failure to
give such notice shall not relieve the indemnifying party or parties from any
liability which it or they may have to the indemnified party for contribution or
otherwise than on account of the provisions of Section 8(a) or (b).  In case any
such proceeding shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party and shall pay as incurred the fees and disbursements of such counsel
related to such proceeding.  In any such proceeding, any indemnified party shall
have the right to retain its own counsel at its own expense.  Notwithstanding
the foregoing, the indemnifying party shall pay as incurred (or within 30 days
of presentation) the fees and expenses of the counsel retained by the
indemnified party in the event (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel, (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them or (iii) the indemnifying party shall have
failed to assume the defense and employ counsel acceptable to the indemnified
party within a reasonable period of time after notice of commencement of the
action.  It is understood that the indemnifying party shall not, in connection
with any proceeding or related proceedings in the same jurisdiction, be liable
for the reasonable fees and expenses of more than one separate firm for all such
indemnified parties.  Such firm shall be designated in writing by you in the
case of parties indemnified pursuant to Section 8(a) and by the Company in the
case of parties indemnified pursuant to Section 8(b).  The indemnifying party
shall not be liable for any settlement of any proceeding effected without its
written consent but if settled with such consent or if there be a final judgment
for the plaintiff, the indemnifying party agrees to indemnify the indemnified
party from and against any loss or liability by reason of such settlement or
judgment.  In addition, the indemnifying party will not, without the prior
written consent of the indemnified party, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action or proceeding
of which indemnification may be sought hereunder (whether or not any indemnified
party is an actual or potential party to such claim, action or proceeding)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action
or proceeding.

          (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
Section 8(a) or (b) above in respect of any 

                                       21
<PAGE>
 
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof) in
such proportion as is appropriate to reflect the relative benefits received by
the Company on the one hand and the Underwriters on the other from the offering
of the Shares. If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company on the one hand and the Underwriters on the
other in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, (or actions or proceedings in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company and the
total underwriting discounts and commissions received by the Underwriters, in
each case as set forth in the table on the cover page of the Prospectus, bear to
the aggregate public offering price of the Shares. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

          The Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 8(d).  The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) referred
to above in this Section 8(d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (d), (i) no Underwriter shall be required to
contribute any amount in excess of the underwriting discounts and commissions
applicable to the Shares purchased by such Underwriter, and (ii) no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation.  The Underwriters' obligations in this
Section 8(d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

          (e) In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 8 hereby
consents to the jurisdiction of any court having jurisdiction over any other
contributing party, agrees that process issuing from such court may be served
upon him or it by any other contributing party and consents to the service of
such process and agrees that any other contributing party may join him or it as
an additional defendant in any such proceeding in which such other contributing
party is a party.

                                       22
<PAGE>
 
          (f) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The
indemnity and contribution agreements contained in this Section 8 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Underwriter or any person controlling
any Underwriter, the Company, its directors or officers or any persons
controlling the Company, (ii) acceptance of any Shares and payment therefor
hereunder, and (iii) any termination of this Agreement.  A successor to any
Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 8.

     9.   Indemnification of QIU.

          (a) The Company agrees to indemnify and hold harmless the QIU, its
directors, its officers and each person, if any, who controls the QIU within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
against any and all losses, claims, damages, liabilities and judgments
(including, without limitation, any legal or other expenses incurred in
connection with investigating or defending any matter, including any action,
that could give rise to any such losses, claims, damages, liabilities or
judgments) related to, based upon or arising out of (i) any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement (or any amendment thereto), the Prospectus (or any amendment or
supplement thereto) or any preliminary prospectus, 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 or (ii) the QIU's
activities as QIU under its engagement pursuant to Section 2 hereof.

          (b) In case any action shall be commenced in any person in respect of
which indemnity may be sought pursuant to Section 9(a) (the "QIU Indemnified
Party"), the QIU Indemnified Party shall promptly notify the Company in writing
and the Company shall assume the defense of such action, including the
employment of counsel reasonably satisfactory to the QIU Indemnified Party and
the payment of all fees and expenses of such counsel, as incurred.  Any QIU
Indemnified Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of the QIU Indemnified Party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the Company, (ii) the Company shall have failed to assume the defense of such
action or employ counsel reasonably satisfactory to the QIU Indemnified Party or
(iii) the named parties to any such action (including any impleaded parties)
include both the QIU Indemnified Party and the Company, and the QIU Indemnified
Party shall have been advised by such counsel that there may be one or more
legal defenses available to it which are different from or additional to those
available to the Company (in which case the Company shall not have the right to
assume the defense of such 

                                       23
<PAGE>
 
action on behalf of the QIU Indemnified Party). In any such case, the Company
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all QIU Indemnified Parties, which firm shall be designated by the QIU, and all
such fees and expenses shall be reimbursed as they are incurred. The Company
shall indemnify and hold harmless the QUI Indemnified Party from and against any
and all losses, claims, damages, liabilities and judgments by reason of any
settlement of any action (i) effected with its written consent or (ii) effected
without its written consent if the settlement is entered into more than twenty
business days after the Company shall have received a request from the QIU
Indemnified Party for reimbursement for the fees and expenses of counsel (in any
case where such fees and expenses are at the expense of the Company) and, prior
to the date of such settlement, the Company shall have failed to comply with
such reimbursement request. The Company shall not, without the prior written
consent of the QIU Indemnified Party, effect any settlement or compromise of, or
consent to the entry of judgment with respect to, any pending or threatened
action in respect of which the QIU Indemnified Party is or could have been a
party and indemnity or contribution may be or could have been sought hereunder
by the QIU Indemnified Party, unless such settlement, compromise or judgment (i)
includes an unconditional release of the QIU Indemnified Party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the QIU Indemnified Party.

          (c) To the extent that the indemnification provided for in this
Section 9 is unavailable to a QIU Indemnified Party or insufficient in respect
of any losses, claims, damages, liabilities or judgments referred to therein,
then the Company, in lieu of indemnifying such QIU Indemnified Party, shall
contribute to the amount paid or payable by such QIU Indemnified Party as a
result of such losses, claims, damages, liabilities and judgments in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the QIU on the other hand from the offering of the
Shares.  If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only the relative benefits referred
to but also the relative fault of the Company on the one hand and the QIU on the
other hand in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or judgments, as well as any other relevant
equitable considerations.  The relative benefits received by the Company on the
one hand and the QIU on the other hand shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company as set forth in the table on the cover page of
the Prospectus, and the fee received by the QIU pursuant to Section 2(d) hereof,
bear to the sum of such total net proceeds and such fee.  The relative fault of
the Company on the one hand and the QIU on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the QIU and the parties
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

                                       24
<PAGE>
 
          The Company and the QIU agree that is would not be just and equitable
if contribution pursuant to this Section 9(c) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable to a QIU Indemnified Party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such QIU Indemnified Party
in connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (d) The remedies provided for in this Section 9 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
QIU Indemnified Party at law or in equity.

     10.  Default by Underwriters.

          If on the Closing Date or the Option Closing Date, as the case may be,
any Underwriter shall fail to purchase and pay for the portion of the Shares
which such Underwriter has agreed to purchase and pay for on such date
(otherwise than by reason of any default on the part of the Company), you, as
Representatives of the Underwriters, shall use your reasonable efforts to
procure within 36 hours thereafter one or more of the other Underwriters, or any
others, to purchase from the Company such amounts as may be agreed upon and upon
the terms set forth herein, the Firm Shares or Option Shares, as the case may
be, which the defaulting Underwriter or Underwriters failed to purchase.  If
during such 36 hours you, as such Representatives, shall not have procured such
other Underwriters, or any others, to purchase the Firm Shares or Option Shares,
as the case may be, agreed to be purchased by the defaulting Underwriter or
Underwriters, then (a) if the aggregate number of shares with respect to which
such default shall occur does not exceed 10% of the Firm Shares or Option
Shares, as the case may be, covered hereby, the other Underwriters shall be
obligated, severally, in proportion to the respective numbers of Firm Shares or
Option Shares, as the case may be, which they are obligated to purchase
hereunder, to purchase the Firm Shares or Option Shares, as the case may be,
which such defaulting Underwriter or Underwriters failed to purchase, or (b) if
the aggregate number of shares of Firm Shares or Option Shares, as the case may
be, with respect to which such default shall occur exceeds 10% of the Firm
Shares or Option Shares, as the case may be, covered hereby, the Company or you
as the Representatives of the Underwriters will have the right, by written
notice given within the next 36-hour period to the parties to this Agreement, to
terminate this Agreement without liability on the part of the non-defaulting
Underwriters or of the Company except to the extent provided in Section 8
hereof.  In the event of a default by any Underwriter or Underwriters, as set
forth in this Section 10, the Closing Date or Option Closing Date, as the case
may be, may be postponed for such period, not exceeding seven days, as you, as
Representatives, may determine in order that the required changes in the
Registration Statement or in the Prospectus or in any other documents or
arrangements may be 

                                       25
<PAGE>
 
effected. The term "Underwriter" includes any person substituted for a
defaulting Underwriter. Any action taken under this Section 10 shall not relieve
any defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

     11.  Notices.

          All communications hereunder shall be in writing and, except as
otherwise provided herein, will be mailed, delivered, telecopied or telegraphed

     12.  Termination.

          This Agreement may be terminated by you by notice to the Company as
follows:

          (a) at any time prior to the earlier of (i) the time the Shares are
released by you for sale by notice to the Underwriters, or (ii) 11:30 a.m. on
the first business day following the date of this Agreement;

          (b) at any time prior to the Closing Date if any of the following has
occurred: (i) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any material adverse change or any
development involving a prospective material adverse change in or affecting the
condition, financial or otherwise, of the Company and its Subsidiaries taken as
a whole or the earnings, business, management, properties, assets, rights,
operations, financial condition or prospects of the Company, whether or not
arising in the ordinary course of business, (ii) any outbreak or escalation of
hostilities or declaration of war or national emergency or other national or
international calamity or crisis or change in economic or political conditions
if the effect of such outbreak, escalation, declaration, emergency, calamity,
crisis or change on the financial markets of the United States would, in your
reasonable judgment, make it impracticable to market the Shares or to enforce
contracts for the sale of the Shares, or (iii) suspension of trading in
securities generally on the New York Stock Exchange or the American Stock
Exchange or limitation on prices (other than limitations on hours or numbers of
days of trading) for securities on either such Exchange, (iv) the enactment,
publication, decree or 

                                       26
<PAGE>
 
other promulgation of any statute, regulation, rule or order of any court or
other governmental authority which in your opinion materially and adversely
affects or may materially and adversely affect the business or operations of the
Company, (v) declaration of a banking moratorium by United States or New York
State authorities, (vi) any downgrading in the rating of the Company's debt
securities by any "nationally recognized statistical rating organization" (as
defined for purposes of Rule 436(g) under the Exchange Act); (vii) the
suspension of trading of the Company's Common Stock by the Commission on the
Nasdaq National Market or (viii) the taking of any action by any governmental
body or agency in respect of its monetary or fiscal affairs which in your
reasonable opinion has a material adverse effect on the securities markets in
the United States; or

          (c) as provided in Sections 6 and 10 of this Agreement.

     13.  Successors.

          This Agreement has been and is made solely for the benefit of the
Underwriters and the Company and their respective successors, executors,
administrators, heirs and assigns, the officers, directors and controlling
persons referred to herein, and the QIU Indemnified Parties and no other person
will have any right or obligation hereunder.  No purchaser of any of the Shares
from any Underwriter shall be deemed a successor or assign merely because of
such purchase.

     14.  Information Provided by Underwriters.

          The Company, and the Underwriters acknowledge and agree that the only
information furnished or to be furnished by any Underwriter to the Company for
inclusion in any Prospectus or the Registration Statement consists of the
information set forth in the last paragraph on the front cover page (insofar as
such information relates to the Underwriters), legends required by Item 502(d)
of Regulation S-K under the Act and the information under the caption
"Underwriting" in the Prospectus.

     15.  Miscellaneous.

          The reimbursement, indemnification and contribution agreements
contained in this Agreement and the representations, warranties and covenants in
this Agreement shall remain in full force and effect regardless of (a) any
termination of this Agreement, (b) any investigation made by or on behalf of any
Underwriter or controlling person thereof, any QIU Indemnified Party or by or on
behalf of the Company or its directors or officers and (c) delivery of and
payment for the Shares under this Agreement.

          This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

          This Agreement shall be governed by, and construed in accordance with,
the laws of the State of Maryland.

                         CERTIFICATE OF INCORPORATION

                                      OF

                     METAWAVE COMMUNICATIONS CORPORATION,

                            A DELAWARE CORPORATION


     The undersigned, Vito Palermo, hereby certifies that:

     1.   He is the duly elected Chief Financial Officer and Secretary,
respectively, of Metawave Communications Corporation, a Delaware corporation.

     2.   The Certificate of Incorporation of this corporation was originally
filed with the Secretary of State of Delaware on July 11, 1995.

     3.   The Certificate of  Incorporation of this corporation shall be amended
and restated to read in full as follows:

                                   ARTICLE I

     The name of this Corporation is Metawave Communications Corporation.

                                  ARTICLE II

     The address of the registered office of this Corporation in the State of
Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle.
The name of its registered agent at such address is The Corporation Trust
Company.

                                  ARTICLE III

     The nature of the business or purposes to be conducted or promoted is to
engage in any lawful act or activity for which corporations may be organized
under the General Corporation Law of Delaware.

                                  ARTICLE IV

     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 that this Corporation is authorized to issue is sixty
million (60,000,000) shares.  Forty million (40,000,000) shares shall be Common
Stock, par value $.0001 per share, and twenty million (20,000,000) shares shall
be Preferred Stock, par value $.0001 per share.

     B.   RIGHTS, PREFERENCES AND RESTRICTIONS OF PREFERRED STOCK.  The
Preferred Stock authorized by this Third Amended and Restated Certificate of
Incorporation may be issued from time to time in one or more series.  The

of 2,760,742 shares, and the Series C Preferred Stock, which series shall

designation thereof, or of any of them. Subject to compliance with applicable
protective voting rights that have been or may be granted to the Preferred Stock
or series thereof in Certificates of Determination or this Corporation's Third
Amended and Restated Certificate of Incorporation ("Protective Provisions"), but
notwithstanding any other rights of the Preferred Stock or any series thereof,
the rights, privileges, preferences and restrictions of any such additional
series may be subordinated to, pari passu with (including, without limitation,
inclusion in provisions with respect to dividends, liquidation and acquisition
preferences, redemption and/or approval of matters by vote or written consent),
or senior to any of those of any present or future class or series of Preferred
or Common Stock. Subject to compliance with applicable Protective Provisions and
unless otherwise specifically provided in the resolution establishing any
series, the Board of Directors shall further have the authority, after the
issuance of shares of a series whose number it has designated, to amend the
resolution establishing such series to decrease the number 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 that they had prior to the
adoption of the resolution originally fixing the number of shares of such
series.

          1.   DIVIDEND PROVISIONS.  Subject to the rights of other series of
Preferred Stock that may from time to time come into existence, the holders of
shares of Series A, Series B, Series C and Series D Preferred Stock shall be
entitled to receive dividends, when, as and if declared by the Board of
Directors, out of any assets legally available therefor, prior and in preference
to any declaration or payment of any dividend (payable other than in Common
Stock or other securities and rights convertible into or entitling the holder
thereof to receive, directly or indirectly, additional shares of Common Stock of
this Corporation) on the Common Stock of this Corporation, (a) at the rate of
$.08 per share of Series A Preferred Stock, $.27 per share of Series B Preferred
Stock, $.49 per share of Series C Preferred Stock, and $.64 per share of Series
D Preferred Stock, per annum (each of such amounts being subject to equitable
adjustment to reflect the effects of any stock dividends, stock splits,
combinations, reverse splits, reclassifications or recapitalizations (herein
referred to as "Adjustment Events")), or (b) if a dividend is paid on the Common
Stock in an amount per share (the "Alternate Rate") which, when multiplied by
the respective numbers of shares of Common Stock into which shares of the Series
A, Series B, Series C or Series D Preferred Stock are then convertible, exceeds
the preferential dividend per share which holders of shares of such series would
otherwise be entitled to receive under clause (a) of this Section 1, then
holders of shares of such series shall be entitled to receive the Alternate Rate
per share of such series in lieu of the preferential dividend set forth in
clause (a) of this Section 1.  Such dividends shall not be cumulative until the
calendar quarter beginning July 1, 2000.  Such dividends shall accrue on each
share from July 1, 2000, if declared

                                      -2-
<PAGE>
 
by the Board of Directors. Such dividends shall be cumulative so that, if such
dividends in respect of any previous or current annual dividend period, at the
annual rate specified above, shall have been declared but not paid, the
deficiency shall first be fully paid before any dividend or other distribution
shall be paid on or declared and set apart for the Common Stock. Any
accumulation of dividends on the Series A, Series B, Series C and Series D
Preferred Stock shall not bear interest. Cumulative dividends with respect to a
share of Series A, Series B, Series C or Series D Preferred Stock that are
accrued, payable and/or in arrears shall, upon conversion of such share to
Common Stock, subject to the rights of other series of Preferred Stock that may
from time to time come into existence, be paid to the extent assets are legally
available therefor either in cash or in Common Stock (valued at the fair market
value on the date of payment as determined by the Board of Directors of this
Corporation). Any amounts for which assets are not legally available shall be
paid promptly as assets become legally available therefor. Any partial payment
will be made pro rata among the holders of such shares.

          2.   LIQUIDATION PREFERENCE

               (a)  In the event of any liquidation, dissolution or winding up
of this Corporation, either voluntary or involuntary, subject to the rights of
other series of Preferred Stock that may from time to time come into existence,
the holders of Series A, Series B, Series C and Series D Preferred Stock shall
be entitled to receive, prior and in preference to any distribution of any of
the assets of this Corporation to the holders of Common Stock by reason of their
ownership thereof, an amount per share equal to the sum of (i) $1.00 for each
outstanding share of Series A Preferred Stock (the "Original Series A Issue
Price"), $3.375 for each outstanding share of Series B Preferred Stock (the
"Original Series B Issue Price"), $6.16 for each outstanding share of Series C
Preferred Stock (the "Original Series C Issue Price") and $8.00 for each
outstanding share of Series D Preferred Stock (the "Original Series D Issue
Price") (each such amount being subject to adjustment for Adjustment Events),
and (ii) an amount equal to declared but unpaid dividends and accrued cumulative
dividends on each such share of Series A, Series B, Series C and Series D
Preferred Stock. If upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Series A, Series B, Series C and Series D
Preferred Stock shall be insufficient to permit the payment to such holders of
the full aforesaid preferential amounts, then, subject to the rights of other
series of Preferred Stock that may from time to time come into existence, the
entire assets and funds of this Corporation legally available for distribution
shall be distributed ratably among the holders of the Series A, Series B, Series
C and Series D Preferred Stock in proportion to the preferential amount each
such holder is otherwise entitled to receive.

               (b)  For purposes of subsections (b), (c), (d) and (e) of this
Section 2, the following definitions shall apply:

                    "Series A Investment Amount" shall mean the Original Series
A Issue Price multiplied by the number of shares of Series A Preferred Stock
outstanding.

                                      -3-
<PAGE>
 
                    "Series B Investment Amount" shall mean the Original Series
B Issue Price multiplied by the number of shares of Series B Preferred Stock
outstanding.

                    "Series C Investment Amount" shall mean the Original Series
C Issue Price multiplied by the number of shares of Series C Preferred Stock
outstanding.

                    "Series D Investment Amount" shall mean the Original Series
D Issue Price multiplied by the number of shares of Series D Preferred Stock
outstanding.

                    "Total Preferred Stock Investment Amount" shall mean the sum
of the Series A Investment Amount, Series B Investment Amount, Series C
Investment Amount and Series D Investment Amount.

                    "Series A Percentage" shall mean the Series A Investment
Amount divided by the Total Preferred Stock Investment Amount.

                    "Series B Percentage" shall mean the Series B Investment
Amount divided by the Total Preferred Stock Investment Amount.

                    "Series C Percentage" shall mean the Series C Investment
Amount divided by the Total Preferred Stock Investment Amount.

                    "Series D Percentage" shall mean the Series D Investment
Amount divided by the Total Preferred Stock Investment Amount.

               (c)  Upon the completion of the distributions required by
subsection (a) of this Section 2 and any other distribution that may be required
with respect to other series of Preferred Stock that may from time to time come
into existence, the remaining assets of this Corporation available for
distribution to stockholders shall be distributed as follows: (i) an aggregate
amount (the "First Distribution Amount") equal to the product of $1.50
multiplied by the number of shares of Series A, Series B, Series C and Series D
Preferred Stock then outstanding (as adjusted for Adjustment Events) shall be
distributed, on a pari passu basis, in an amount equal to the Series A
Percentage multiplied by the First Distribution Amount, ratably among the
holders of Series A Preferred Stock, the Series B Percentage multiplied by the
First Distribution Amount, ratably among the holders of Series B Preferred
Stock, the Series C Percentage multiplied by the First Distribution Amount,
ratably among the holders of Series C Preferred Stock, and the Series D
Percentage multiplied by the First Distribution Amount, ratably among the
holders of Series D Preferred Stock, and (ii) an amount per share equal to $1.50
for each outstanding share of Common Stock (as adjusted for Adjustment Events),
in addition to the amounts paid pursuant to subsection (a) of this Section 2,
shall be distributed ratably among the holders of Common Stock. If the assets
and funds thus distributed among the holders of the Series A, Series B, Series C
and Series D Preferred Stock and the holders of the Common Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, subject to the rights of other series of Preferred
Stock that may from time to time come into existence, the entire assets and
funds of this Corporation legally available for

                                      -4-
<PAGE>
 
distribution shall be distributed ratably among the holders of the Series A,
Series B, Series C and Series D Preferred Stock and the holders of the Common
Stock in proportion to the preferential amount each such holder is otherwise
entitled to receive under this subsection (c).

               (d)  Upon the completion of the distributions required by
subsections (a) and (c) of this Section 2 and any other distribution that may be
required with respect to other series of Preferred Stock that may from time to
time come into existence, the remaining assets of this Corporation available for
distribution to stockholders shall be distributed as follows: (i) an aggregate
amount (the "Second Distribution Amount") equal to the product of $3.5625
multiplied by the number of shares of Series B, Series C and Series D Preferred
Stock then outstanding (as adjusted for Adjustment Events) shall be distributed,
on a pari passu basis, in an amount equal to the Series A Percentage multiplied
by the Second Distribution Amount, ratably among the holders of Series A
Preferred Stock, the Series B Percentage multiplied by the Second Distribution
Amount, ratably among the holders of Series B Preferred Stock, the Series C
Percentage multiplied by the Second Distribution Amount, ratably among the
holders of Series C Preferred Stock, and the Series D Percentage multiplied by
the Second Distribution Amount, ratably among the holders of Series D Preferred
Stock, and (ii) an amount per share equal to $3.5625 for each outstanding share
of Common Stock (as adjusted for Adjustment Events), in addition to the amounts
paid pursuant to subsections (a) and (c) of this Section 2, shall be distributed
ratably among the holders of Common Stock. If the assets and funds thus
distributed among the holders of the Series A, Series B, Series C and Series D
Preferred Stock and the holders of the Common Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then, subject to the rights of other series of Preferred Stock that may from
time to time come into existence, the entire assets and funds of this
Corporation legally available for distribution shall be distributed ratably
among the holders of the Series A, Series B, Series C and Series D Preferred
Stock and the holders of the Common Stock in proportion to the preferential
amount each such holder is otherwise entitled to receive under this subsection
(d).

               (e)  Upon the completion of the distributions required by
subsections (a), (c) and (d) of this Section 2 and any other distribution that
may be required with respect to other series of Preferred Stock that may from
time to time come into existence, the remaining assets of this Corporation
available for distribution to stockholders shall be distributed as follows: (i)
an aggregate amount (the "Third Distribution Amount") equal to the product of
$4.1775 multiplied by the number of shares of Series C and Series D Preferred
Stock then outstanding (as adjusted for Adjustment Events) shall be distributed,
on a pari passu basis, in an amount equal to the Series A Percentage multiplied
by the Third Distribution Amount, ratably among the holders of Series A
Preferred Stock, the Series B Percentage multiplied by the Third Distribution
Amount, ratably among the holders of Series B Preferred Stock, the Series C
Percentage multiplied by the Third Distribution Amount, ratably among the
holders of Series C Preferred Stock, and the Series D Percentage multiplied by
the Third Distribution Amount, ratably among the holders of Series D Preferred
Stock, and (ii) an amount per share equal to $4.1775 for each outstanding share
of Common Stock (as adjusted for Adjustment Events), in addition to the amounts
paid pursuant to subsections (a), (c) and (d) of this Section 2, shall be

                                      -5-
<PAGE>
 
distributed ratably among the holders of Common Stock. If the assets and funds
thus distributed among the holders of the Series A, Series B, Series C and
Series D Preferred Stock and the holders of the Common Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, subject to the rights of other series of Preferred
Stock that may from time to time come into existence, the entire assets and
funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A, Series B, Series C and
Series D Preferred Stock and the holders of the Common Stock in proportion to
the preferential amount each such holder is otherwise entitled to receive under
this subsection (e).

               (f)  Upon the completion of the distributions required by
subsections (a), (c), (d) and (e) of this Section 2 and any other distribution
that may be required with respect to other series of Preferred Stock that may
from time to time come into existence, the remaining assets of this Corporation
available for distribution to stockholders shall be distributed as follows: (i)
an aggregate amount (the "Fourth Distribution Amount") equal to the product of
$2.76 multiplied by the number of shares of Series D Preferred Stock then
outstanding (as adjusted for Adjustment Events) shall be distributed, on a pari
passu basis, in an amount equal to the Series A Percentage multiplied by the
Fourth Distribution Amount, ratably among the holders of Series A Preferred
Stock, the Series B Percentage multiplied by the Fourth Distribution Amount,
ratably among the holders of Series B Preferred Stock, the Series C Percentage
multiplied by the Fourth Distribution Amount, ratably among the holders of
Series C Preferred Stock, and the Series D Percentage multiplied by the Fourth
Distribution Amount, ratably among the holders of Series D Preferred Stock, and
(ii) an amount per share equal to $2.76 for each outstanding share of Common
Stock (as adjusted for Adjustment Events), in addition to the amounts paid
pursuant to subsections (a), (c), (d) and (e) of this Section 2, shall be
distributed ratably among the holders of Common Stock. If the assets and funds
thus distributed among the holders of the Series A, Series B, Series C and
Series D Preferred Stock and the holders of the Common Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, subject to the rights of other series of Preferred
Stock that may from time to time come into existence, the entire assets and
funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A, Series B, Series C and
Series D Preferred Stock and the holders of the Common Stock in proportion to
the preferential amount each such holder is otherwise entitled to receive under
this subsection (f).

               (g)  Upon the completion of the distributions required by
subsections (a), (c), (d)(e), and (f) of this Section 2 and any other
distribution that may be required with respect to other series of Preferred
Stock that may from time to time come into existence, if assets remain in this
Corporation, the holders of Series A, Series B, Series C and Series D Preferred
Stock shall receive no further distributions and the holders of the Common Stock
of this Corporation shall receive all of the remaining assets of this
Corporation pro rata based on the number of shares of Common Stock held by each.

               (h)  (i)  For purposes of this Section 2, a liquidation,
dissolution or winding up of this Corporation shall be deemed to be occasioned
by, or to include, (A) the acquisition of this Corporation by another entity by
means of any transaction or series of related transactions (including, without
limitation, any reorganization, merger or consolidation) that results in the
transfer of fifty percent (50%) or more of the outstanding voting power of this
Corporation; or (B) a sale of all or substantially all of the assets of this
Corporation.

                    (ii) In any of such events, if the consideration received by
this Corporation is other than cash, the value of such consideration will be
deemed its fair market value. Any securities shall be valued as follows:

                         (A)  Securities not subject to investment letter or
other similar restrictions on free marketability covered by (B) below:

                              (1)  If traded on a securities exchange or through
the NASDAQ National Market, the value shall be deemed to be the average of the
closing prices of the securities on such quotation system over the thirty (30)
day period ending three (3) days prior to the closing;

                              (2)  If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the thirty (30) day period ending three (3) days
prior to the closing; and

                              (3)  If there is no active public market, the
value shall be the fair market value thereof, as mutually determined by this
Corporation and the holders of at least a majority of the voting power of all
then outstanding shares of Series A, Series B, Series C and Series D Preferred
Stock.

                         (B)  The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a stockholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (A)(1), (2) or (3) to reflect the approximate fair
market value thereof as mutually determined by this Corporation and the holders
of at least a majority of the voting power of all then outstanding shares of
Series A, Series B, Series C and Series D Preferred Stock.

                    (iii) In the event the requirements of this subsection 2(f)
are not complied with, this Corporation shall forthwith either:

                         (A)  cause such closing to be postponed until such time
as the requirements of this Section 2(f) have been complied with; or

                         (B)  cancel such transaction, in which event the
rights, preferences and privileges of the holders of the Series A, Series B,
Series C and Series D

                                      -7-
<PAGE>
 
Preferred Stock shall revert to and be the same as such rights, preferences and
privileges existing immediately prior to the date of the first notice referred
to in subsection 2(f)(iv) hereof.

                    (iv) This Corporation shall give each holder of record of
Series A, Series B, Series C and Series D Preferred Stock written notice of such
impending transaction not later than twenty (20) days prior to the stockholders'
meeting called to approve such transaction, if any, or twenty (20) days prior to
the closing of such transaction, whichever is earlier, and shall also notify
such holders in writing of the final approval of such transaction. The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 2, and this Corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than twenty (20) days after this
Corporation has given the first notice provided for herein or sooner than ten
(10) days after this Corporation has given notice of any material changes
provided for herein; provided, however, that such periods may be shortened upon
the written consent of the holders of Preferred Stock that are entitled to such
notice rights or similar notice rights and that represent at least a majority of
the voting power of all then outstanding shares of Series A, Series B, Series C
and Series D Preferred Stock.

          3.   REDEMPTION

               (a)  Subject to the rights of other series of Preferred Stock
that may from time to time come into existence, upon receipt by this
Corporation, within the six (6) month period commencing December 31, 2000, of a
written request (the "Redemption Request") from the holders of not less than
fifty percent (50%) of the then outstanding shares of Series A, Series B, Series
C and Series D Preferred Stock (voting together as a single class and not as a
separate series, and on an as converted basis) that all or, if less than all, a
specified percentage of such holders' shares of such series (which percentage
shall be the same for the Series A, Series B, Series C and Series D Preferred
Stock) be redeemed, and concurrently with surrender by such holders of the
certificates representing such shares, this Corporation shall, to the extent it
may lawfully do so, redeem (i) in four (4) equal annual installments commencing
no later than the first anniversary of the receipt of the Redemption Request
(each such payment date being referred to herein as a "Redemption Date"), or
(ii) at the Corporation's election, in fewer annual installments, including
without limitation, a single lump sum payment, the shares specified in such
request by paying in cash therefor a sum per share equal to $1.00 per share of
Series A Preferred Stock (as adjusted for Adjustment Events) to be redeemed plus
all declared but unpaid dividends and accrued cumulative dividends on such share
(the "Series A Redemption Price"), a sum per share equal to $3.375 per share of
Series B Preferred Stock (as adjusted for Adjustment Events) to be redeemed plus
all declared but unpaid dividends and accrued cumulative dividends on such share
(the "Series B Redemption Price"), a sum per share equal to $6.16 per share of
Series C Preferred Stock (as adjusted for Adjustment Events) to be redeemed plus
all declared but unpaid dividends and accrued cumulative dividends on such share
(the "Series C Redemption Price") and a sum per share equal to $8.00 per share
of Series D Preferred Stock (as adjusted for Adjustment Events) to be redeemed
plus all declared but unpaid dividends and accrued cumulative dividends on such
share (the "Series D Redemption Price"). The holders of the

                                      -8-
<PAGE>
 
Series A, Series B, Series C and Series D Preferred Stock may exercise their
redemption rights pursuant to this subsection 3(a) only during the six (6) month
period commencing December 31, 2000, and any redemption payments shall be made
on a pro rata basis among the holders of all shares of Series A, Series B,
Series C and Series D Preferred Stock to be redeemed in proportion to the
aggregate redemption payments due to each such holder.

               (b)  Subject to the rights of other series of Preferred Stock
that may from time to time come into existence, at least fifteen (15) but no
more than thirty (30) days prior to each Redemption Date, written notice shall
be mailed, first class postage prepaid, to each holder of record (at the close
of business on the business day next preceding the day on which notice is given)
of the Series A, Series B, Series C and Series D Preferred Stock to be redeemed
on the Redemption Date, at the address last shown on the records of this
Corporation for such holder, notifying such holder of the redemption to be
effected, specifying the number of shares to be redeemed from such holder, the
Redemption Date or Dates, the Redemption Price (as applicable), the place at
which payment may be obtained and calling upon such holder to surrender to this
Corporation, in the manner and at the place designated, his, her or its
certificate or certificates representing the shares to be redeemed (the
"Redemption Notice") on such Redemption Date or Dates. Except as provided in
subsection 3(c), on or after each Redemption Date, each holder of Series A,
Series B, Series C and Series D Preferred Stock to be redeemed shall surrender
to this Corporation the certificate or certificates representing such shares, in
the manner and at the place designated in the Redemption Notice, and thereupon
the applicable Redemption Price of such shares shall be payable to the order of
the person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be canceled. In the event less
than all the shares represented by any such certificate are redeemed on a
Redemption Date, a new certificate shall be issued representing the unredeemed
shares. Any certificate issued after the date of the Redemption Request shall
bear a legend indicating that such shares are subject to redemption by the
Company pursuant to the Redemption Request. Shares subject to redemption by the
Company pursuant to the Redemption Request shall be transferable (subject to
redemption by the Company) but shall not be convertible into Common Stock except
as provided in subsection 4(a) of Division B of this Article IV.

               (c)  From and after each Redemption Date, unless there shall have
been a default in payment of the Redemption Price, all rights of the holders of
shares of Series A, Series B, Series C or Series D Preferred Stock designated
for redemption on such Redemption Date, as holders of Series A, Series B, Series
C or Series D Preferred Stock (except the right to receive the applicable
Redemption Price without interest upon surrender of their certificate or
certificates), shall cease with respect to such shares, and such shares shall
not thereafter be transferred on the books of this Corporation or be deemed to
be outstanding for any purpose whatsoever. Subject to the rights of other series
of Preferred Stock that may from time to time come into existence, if the funds
of this Corporation legally available for redemption of shares of Series A,
Series B, Series C and Series D Preferred Stock on any Redemption Date are
insufficient to redeem the total number of shares of Series A, Series B, Series
C and Series D Preferred Stock to be redeemed on such date, those funds that are
legally available will be used to redeem the maximum possible number of such
shares ratably among the holders of such

                                      -9-
<PAGE>
 
shares to be redeemed such that each holder of a share of Series A, Series B,
Series C and Series D Preferred Stock receives the same percentage of the
applicable Series A Redemption Price, Series B Redemption Price, Series C
Redemption Price or Series D Redemption Price. The shares of Series A, Series B,
Series C and Series D Preferred Stock not redeemed shall remain outstanding and
entitled to all the rights and preferences provided herein. Subject to the
rights of other series of Preferred Stock that may from time to time come into
existence, at any time thereafter when additional funds of this Corporation are
legally available for the redemption of such shares of Series A, Series B,
Series C and Series D Preferred Stock, such funds will immediately be used to
redeem the balance of the shares that this Corporation has become obligated but
has failed to redeem on any Redemption Date.

               (d)  On or prior to each Redemption Date, this Corporation shall
deposit the Redemption Price of all shares of Series A, Series B, Series C and
Series D Preferred Stock designated for redemption in the Redemption Notice and
not yet redeemed or converted with a bank or trust corporation having aggregate
capital and surplus in excess of $100,000,000 as a trust fund for the benefit of
the respective holders of the shares designated for redemption and not yet
redeemed, with irrevocable instructions and authority to the bank or trust
corporation to publish the notice of redemption thereof and pay the Redemption
Price for such shares to their respective holders on or after the Redemption
Date, upon receipt of notification from this Corporation that such holder has
surrendered his, her or its share certificate to this Corporation pursuant to
subsection 3(b) above.  As of the date of such deposit (even if prior to the
Redemption Date), the deposit shall constitute full payment of the shares to
their holders, and from and after the date of the deposit the shares so called
for redemption shall be redeemed and shall be deemed to be no longer
outstanding, and the holders thereof shall cease to be stockholders with respect
to such shares and shall have no rights with respect thereto except the rights
to receive from the bank or trust corporation payment of the Redemption Price of
the shares, without interest, upon surrender of their certificates therefor, and
the right to convert such shares as provided in Article IV(B)(4) hereof.  Such
instructions shall also provide that any moneys deposited by this Corporation
pursuant to this subsection 3(d) for the redemption of shares thereafter
converted into shares of this Corporation's Common Stock pursuant to Article
IV(B)(4) hereof prior to the Redemption Date shall be returned to this
Corporation forthwith upon such conversion.  The balance of any moneys deposited
by this Corporation pursuant to this subsection 3(d) remaining unclaimed at the
expiration of two (2) years following each Redemption Date shall thereafter be
returned to this Corporation upon its request expressed in a resolution of its
Board of Directors.

          4.   CONVERSION.  The shares of Series A, Series B, Series C and
Series D Preferred Stock shall be subject to conversion as follows (the
"Conversion Rights"):

               (a)  RIGHT TO CONVERT.  Each share of Series A, Series B, Series
C and 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 and on or prior to
the fifth day prior to the first Redemption Date, if any, as may have been fixed
in any Redemption Notice with respect to such share, at the office of this
Corporation or any transfer agent for such stock, into such number of fully paid
and

                                      -10-
<PAGE>
 
nonassessable shares of Common Stock as is determined by dividing the
Original Series A Issue Price, Original Series B Issue Price, Original Series C
Issue Price or Original Series D Issue Price, as the case may be, by the
respective Conversion Price applicable to such share, determined as hereafter
provided, in effect on the date the certificate is surrendered for conversion.
The initial Conversion Price per share for shares of Series A Preferred Stock
shall be the Original Series A Issue Price, the initial Conversion Price per
share for shares of Series B Preferred Stock shall be the Original Series B
Issue Price, the initial Conversion Price per share for shares of Series C
Preferred Stock shall be the Original Series C Issue Price and the initial
Conversion Price per share for shares of Series D Preferred Stock shall be the
Original Series D Issue Price; provided, however, that the Conversion Price for
the Series A, Series B, Series C and Series D Preferred Stock shall be subject
to adjustment as set forth in subsection 4(d).

               (b)  AUTOMATIC CONVERSION.  Each share of the Series A, Series B,
Series C and Series D Preferred Stock shall automatically be converted into
shares of Common Stock at the respective Conversion Price at the time in effect
for such Series A, Series B, Series C or Series D Preferred Stock immediately
upon the earlier of (i) the closing of a sale of the Corporation's Common Stock
in a firm commitment underwritten public offering pursuant to a registration
statement under the Securities Act of 1933, as amended, the public offering
price of which was not less than $9.25 per share (adjusted to reflect Adjustment
Events) and $15,000,000 in the aggregate, or (ii) the date specified by written
consent or agreement of the holders of two-thirds (2/3) of the aggregate number
of shares of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock then outstanding (voting together
as a single class and not as a separate series, and on an as converted basis).

               (c)  MECHANICS OF CONVERSION.  Before any holder of Series A,
Series B, Series C or Series D Preferred Stock shall be entitled to convert the
same into shares of Common Stock, he or she shall surrender the certificate or
certificates therefor, duly endorsed, at the office of this Corporation or of
any transfer agent for the Series A, Series B, Series C or Series D Preferred
Stock, and shall give written notice to this Corporation at its principal
corporate office of the election to convert the same and shall state therein the
name or names in which the certificate or certificates for shares of Common
Stock are to be issued. This Corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series A, Series
B, Series C or Series D Preferred Stock, or to the nominee or nominees of such
holder, 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, Series B, Series C 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 as
of such date. If the conversion is in connection with an underwritten offering
of securities registered pursuant to the Securities Act of 1933, as amended, the
conversion may, at the option of any holder tendering Series A, Series B, Series
C or Series D Preferred Stock for conversion, be conditioned upon the closing
with the underwriters of the sale of securities pursuant to such offering, in
which event the person(s) entitled to receive the Common Stock upon conversion
of the Series A, Series B,

                                      -11-
<PAGE>
 
Series C or Series D Preferred Stock shall not be deemed to have converted such
Series A, Series B, Series C or Series D Preferred Stock until immediately prior
to the closing of such sale of securities.

               (d)  Conversion Price Adjustments of Preferred Stock for Certain
Dilutive Issuances, Splits and Combinations. The Conversion Price of the Series
A, Series B, Series C and Series D Preferred Stock shall be subject to
adjustment from time to time as follows:

                    (i)  (A)  If this Corporation shall issue, after the date
upon which any shares of Series D Preferred Stock were first issued (the
"Purchase Date"), any Additional Stock (as defined below) without consideration
or for a consideration per share less than the respective Conversion Price for
the Series A, Series B, Series C or Series D Preferred Stock in effect
immediately prior to the issuance of such Additional Stock, the Conversion Price
for such series in effect immediately prior to the issuance shall forthwith
(except as otherwise provided in this clause (i)) be adjusted to a price
determined by multiplying the Conversion Price of such series in effect
immediately prior to such issuance by a fraction, the numerator of which shall
be the number of shares of Common Stock outstanding immediately prior to such
issuance (including shares of Common Stock deemed to be issued pursuant to
subsection 4(d)(i)(E)) plus the number of shares of Common Stock that the
aggregate consideration received by this Corporation for such issuance would
purchase at such Conversion Price; and the denominator of which shall be the
number of shares of Common Stock outstanding immediately prior to such issuance
(including shares of Common Stock deemed to be issued pursuant to subsection
4(d)(i)(E)) plus the number of shares of such Additional Stock. Notwithstanding
the foregoing, no such Conversion Price adjustment shall occur pursuant to this
subsection 4(d)(i) if prior to the issuance of the Additional Stock this
Corporation shall have obtained a written waiver of the adjustment provided for
in this subsection, which waiver shall have been approved by the holders of not
less than sixty-five percent (65%) of each series of Preferred Stock that would
otherwise be entitled to adjustment of its Conversion Price hereunder.

                         (B)  No adjustment of the Conversion Price for the
Series A, Series B, Series C or Series D Preferred Stock shall be made in an
amount less than one cent per share, provided that any adjustments that are not
required to be made by reason of this sentence shall be carried forward and
shall be either taken into account in any subsequent adjustment made prior to
three (3) years from the date of the event giving rise to the adjustment being
carried forward, or shall be made at the end of the three (3) years from the
date of the event giving rise to the adjustment being carried forward. Except to
the limited extent provided for in subsections 4(d)(i)(E)(3), (E)(4) and (E)(5),
no adjustment of such Conversion Price pursuant to this subsection 4(d)(i) shall
have the effect of increasing the Conversion Price above the Conversion Price in
effect immediately prior to such adjustment.

                         (C)  In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
before deducting

                                      -12-
<PAGE>
 
any reasonable discounts, commissions or other expenses allowed, paid
or incurred by this Corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

                         (D)  In the case of the issuance of the Common Stock
for a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair value thereof as determined by the
Board of Directors irrespective of any accounting treatment.

                         (E)  In the case of the issuance (whether before, on or
after the Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this subsection 4(d)(i) and subsection 4(d)(ii):

                              (1)  The aggregate maximum number of shares of
Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including without limitation, the passage of time,
but without taking into account potential antidilution adjustments) of such
options to purchase or rights to subscribe for Common Stock shall be deemed to
have been issued at the time such options or rights were issued and for a
consideration equal to the consideration (determined in the manner provided in
subsections 4(d)(i)(C) and 4(d)(i)(D)), if any, received by this Corporation
upon the issuance of such options or rights plus the minimum exercise price
provided in such options or rights (without taking into account potential
antidilution adjustments) for the Common Stock covered thereby.

                              (2)  The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by this Corporation for any such
securities and related options or rights, plus the minimum additional
consideration, if any, to be received by this Corporation (without taking into
account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in
subsections 4(d)(i)(C) and 4(d)(i)(D)).

                              (3)  In the event of any change in the number of
shares of Common Stock deliverable or in the consideration payable to this
Corporation upon exercise of such options or rights or upon conversion of or in
exchange for such convertible or exchangeable securities (excluding a change
pursuant to subsection 4(d)(i) in the number of shares of Common Stock issuable
upon conversion of shares of Preferred Stock), the Conversion

                                      -13-
<PAGE>
 
Price of the Series A, Series B, Series C or Series D Preferred Stock, to the
extent in any way affected by or computed using such options, rights or
securities, shall be recomputed to reflect such change, but no further
adjustment shall be made for the actual issuance of Common Stock or any payment
of such consideration upon the exercise of any such options or rights or the
conversion or exchange of such securities.

                              (4)  Upon the expiration of any such options or
rights, the termination of any such rights to convert or exchange, or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price of the Series A, Series B, Series C or Series D
Preferred Stock, to the extent in any way affected by or computed using such
options, rights or securities or options or rights related to such securities
shall be recomputed to reflect the issuance of only the number of shares of
Common Stock (and convertible or exchangeable securities that remain in effect)
actually issued upon the exercise of such options or rights, upon the conversion
or exchange of such securities, or upon the exercise of the options or rights
related to such securities.

                              (5)  The number of shares of Common Stock deemed
issued and the consideration deemed paid therefor pursuant to subsections
4(d)(i)(E)(1) and (2) shall be appropriately adjusted to reflect any change,
termination or expiration of the type described in either subsection
4(d)(i)(E)(3) or (4).

                    (ii) "Additional Stock" shall mean any shares of Common
Stock issued (or deemed to have been issued pursuant to subsection 4(d)(i)(E))
by this Corporation after the Purchase Date other than:

                         (A)  shares of Common Stock issued pursuant to a
transaction described in subsection 4(d)(iii) hereof;

                         (B)  shares of Common Stock issuable or issued to
employees, consultants or directors of this Corporation, or affiliates of any
such persons, pursuant to a stock option plan, restricted stock plan or grant
approved by the Board of Directors of this Corporation;

                         (C)  shares of Common Stock issuable or issued to
vendors, suppliers, equipment lessors or bank lenders to this Corporation, or
affiliates of any such persons, where such issuance is not principally for the
purpose of raising additional equity capital for this Corporation;

                         (D)  shares of Common Stock issued or issuable upon
conversion of shares of Series A, Series B, Series C and Series D Preferred
Stock of this Corporation (including additional shares of Common Stock issuable
upon conversion thereof as a result of the operation of subsection 4(d)(i));

                                     -14-
<PAGE>
 
                         (E)  shares of Common Stock issuable or issued upon
conversion or exercise of convertible or exercisable securities of this
Corporation outstanding as of the date of this Third Amended and Restated
Certificate of Incorporation;

                         (F)  shares of Common Stock issued pursuant to the
acquisition of another corporation or entity, or any product line, intellectual
property or technology, by this Corporation or any subsidiary of this
Corporation by means of merger, consolidation, purchase of assets or other
transaction of series of related transactions approved by the Board of Directors
of this Corporation and, in the case of an acquisition of another corporation or
entity, whereby this Corporation or its shareholders own a majority of the
voting power of such other corporation or entity following such acquisition; and

                         (G)  shares of Common Stock issued to corporate
partners or in connection with other strategic alliances approved by the Board
of Directors of this Corporation.

                    (iii) In the event this Corporation should at any time or
from time to time after the Purchase Date fix a record date for the effectuation
of a split or subdivision of the outstanding shares of Common Stock or 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 convertible into, or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the respective
Conversion Prices of the Series A, Series B, Series C and Series D Preferred
Stock shall be appropriately decreased so that the number of shares of Common
Stock issuable on conversion of each share of each such series shall be
increased in proportion to such increase of the aggregate of shares of Common
Stock outstanding and those issuable with respect to such Common Stock
Equivalents with the number of shares issuable with respect to Common Stock
Equivalents determined from time to time in the manner provided for deemed
issuances in subsection 4(d)(i)(E).

                    (iv) If the number of shares of Common Stock outstanding at
any time after the Purchase Date is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date of such
combination, the respective Conversion Prices for the Series A, Series B, Series
C and Series D Preferred Stock shall be appropriately increased so that the
number of shares of Common Stock issuable on conversion of each share of each
such series shall be decreased in proportion to such decrease in outstanding
shares.

               (e)  OTHER DISTRIBUTIONS.  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 (excluding cash
dividends) or options or rights not referred

                                      -15-
<PAGE>
 
to in subsection 4(d)(iii), then, in each such case for the purpose of this
subsection 4(e), the holders of the Series A, Series B, Series C and Series D
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of this Corporation into which their shares of Series A, Series B, Series
C and Series D Preferred Stock are convertible as of the record date fixed for
the determination of the holders of Common Stock of this Corporation entitled to
receive such distribution.

               (f)  RECAPITALIZATION.  If at any time or from time to time there
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or in Section 2) provision shall be made so that the holders of
the Series A, Series B, Series C and Series D Preferred Stock shall thereafter
be entitled to receive upon conversion of the Series A, Series B, Series C and
Series D Preferred Stock the number of shares of stock or other securities or
property of this Corporation or otherwise to which a holder of Common Stock
deliverable upon conversion would have been entitled on such recapitalization.
In any such case, appropriate adjustment shall be made in the application of the
provisions of this Section 4 with respect to the rights of the holders of the
Series A, Series B, Series C and Series D Preferred Stock after the
recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
purchasable upon conversion of the Series A, Series B, Series C and Series D
Preferred Stock) shall be applicable after that event as nearly equivalent as
may be practicable.

               (g)  NO IMPAIRMENT.  This Corporation will not, by amendment of
its Third Amended and Restated Certificate of Incorporation or through any
reorganization, recapitalization, transfer of assets, consolidation, 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 this Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 4 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, Series B, Series C and
Series D Preferred Stock against impairment.

               (h)  NO FRACTIONAL SHARES AND CERTIFICATE AS TO ADJUSTMENTS

                    (i)  No fractional shares shall be issued upon the
conversion of any share or shares of the Series A, Series B, Series C or Series
D Preferred Stock, and the number of shares of Common Stock to be issued shall
be rounded to the nearest whole share. Whether or not fractional shares are
issuable upon such conversion shall be determined on the basis of the total
number of shares of Series A, Series B, Series C or Series D Preferred Stock the
holder is at the time converting into Common Stock and the number of shares of
Common Stock issuable upon such aggregate conversion.

                    (ii) Upon the occurrence of each adjustment or readjustment
of the Conversion Price of Series A, Series B, Series C or Series D Preferred
Stock pursuant to this

                                      -16-
<PAGE>
 
Section 4, this 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 Series A, Series B, Series C and Series D Preferred
Stock a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. This
Corporation shall, upon the written request at any time of any holder of Series
A, Series B, Series C or Series D Preferred Stock, furnish or cause to be
furnished to such holder a like certificate setting forth (A) such adjustment
and readjustment, (B) the Conversion Price for such series of Preferred Stock at
the time in effect, and (C) the number of shares of Common Stock and the amount,
if any, of other property that at the time would be received upon the conversion
of a share of such series of Preferred Stock.

               (i)  NOTICES OF RECORD DATE.  In the event of any taking by this
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 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, this
Corporation shall mail to each holder of Series A, Series B, Series C and Series
D Preferred Stock, at least 20 days prior to the date specified therein, a
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.

               (j)  RESERVATION OF STOCK ISSUABLE UPON CONVERSIION.  This
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, Series B, Series C 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 outstanding shares of the
Series A, Series B, Series C 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 then outstanding shares of the Series
A, Series B, Series C and Series D Preferred Stock, in addition to such other
remedies as shall be available to the holder of such Preferred Stock, this
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 purposes,
including, without limitation, engaging in best efforts to obtain the requisite
stockholder approval of any necessary amendment to this Third Amended and
Restated Certificate of Incorporation.

               (k) NOTICES.  Any notice required by the provisions of this
Section 4 to be given to the holders of shares of Series A, Series B, Series C
and Series D Preferred Stock shall be deemed given if deposited in the United
States mail, postage prepaid, and addressed to each holder of record at his
address appearing on the books of this Corporation.

                                      -17-

          5.   VOTING RIGHTS

               (a)  GENERAL VOTING RIGHTS.  The holder of each share of Series
A, Series B, Series C and Series D Preferred Stock shall have the right to one
vote for each share of Common Stock into which such Series A, Series B, Series C
and Series D Preferred Stock could then be converted, and with respect to such
vote, such holder shall have full voting rights and powers equal to the voting
rights and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any stockholders' meeting in
accordance with the bylaws of this Corporation, and shall be entitled to vote,
together with holders of Common Stock, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not,
however, be permitted and any fractional voting rights available on an as
converted basis (after aggregating all shares into which shares of Series A,
Series B, Series C and Series D Preferred Stock held by each holder could be
converted) shall be rounded to the nearest whole number (with one-half being
rounded upward).

               (b)  VOTING FOR THE ELECTION OF DIRECTORS.  As long as an
aggregate of at least 9,589,584 of the shares of Series A, Series B, Series C
and Series D Preferred Stock (which number shall be equitably adjusted to
reflect Adjustment Events) remain outstanding, the holders of shares of Series
A, Series B, Series C and Series D Preferred Stock, voting together as a single
voting group, shall be entitled to elect three (3) directors of this Corporation
at each annual election of directors. If the aggregate number of shares of
Series A, Series B, Series C and Series D Preferred Stock that remain
outstanding shall be between 6,393,056 and 9,589,583 inclusive (which numbers
shall be equitably adjusted to reflect Adjustment Events), the holders of shares
of Series A, Series B, Series C and Series D Preferred Stock, voting together as
a single voting group, shall be entitled to elect two (2) directors of this
Corporation at each annual election of directors. If the aggregate number of
shares of Series A, Series B, Series C and Series D Preferred Stock that remain
outstanding shall be between 3,196,528 and 6,393,055 inclusive (which numbers
shall be equitably adjusted to reflect Adjustment Events), the holders of shares
of Series A, Series B, Series C and Series D Preferred Stock, voting together as
a single voting group, shall be entitled to elect one (1) director of this
Corporation at each annual election of directors. The holders of outstanding
Common Stock shall be entitled to elect two (2) directors of this Corporation at
each annual election of directors. The holders of Series A, Series B, Series C
and Series D Preferred Stock and Common Stock (voting together as a single
voting group, and on an as-converted basis) shall be entitled to elect any
remaining directors of this Corporation.

               In the case of any vacancy (other than a vacancy caused by
removal) in the office of a director occurring among the directors elected by
the holders of a class or series of stock pursuant to this Section 5(b), the
remaining directors so elected by that class or series may by affirmative vote
of a majority thereof (or the remaining director so elected if there be but one,
or if there are no such directors remaining, by the affirmative vote of the
holders of a majority of the shares of that class or series), elect a successor
or successors to hold office for the unexpired term of the director or directors
whose place or places shall be vacant. Any director who shall have been elected
by the holders of a class or series of stock or by any directors so

                                     -18-
<PAGE>
 
elected as provided in the immediately preceding sentence hereof may be removed
during the aforesaid term of office, either with or without cause, by, and only
by, the affirmative vote of the holders of the shares of the class or series of
stock entitled to elect such director or directors, given either at a special
meeting of such stockholders duly called for that purpose or pursuant to a
written consent of stockholders, and any vacancy thereby created may be filled
by the holders of that class or series of stock represented at the meeting or
pursuant to unanimous written consent.

          6.  PROTECTIVE PROVISIONS.  Subject to the rights of other series of
Preferred Stock that may from time to time come into existence, this Corporation
shall not take any of the following actions without first obtaining the approval
(by vote or written consent, as provided by law) of the holders of at least a
majority of the shares of Series A, Series B, Series C and Series D Preferred
Stock then outstanding, voting together as a single class and not as separate
series on an as converted basis, provided, however, that in the event that the
aggregate number of shares of Series A, Series B, Series C and Series D
Preferred Stock then outstanding represent less than twenty percent (20%) of the
sum of the aggregate number of all shares of Preferred Stock then outstanding on
an as-converted basis (i.e., after aggregating all shares into which shares of
Preferred Stock could be converted) plus Common Stock then outstanding, then the
protective provisions of this Section 6 shall cease to be of any force or effect
and shall not bind this Corporation:

               (a)  sell, convey, or otherwise dispose of all or substantially
all of its property or business or merge into or consolidate with any other
corporation (other than a wholly-owned subsidiary corporation) or effect any
transaction or series of related transactions in which more than fifty percent
(50%) of the voting power of this Corporation is disposed of;

               (b)  dissolve, wind-up or liquidate this Corporation;

               (c)  alter, change or reclassify the rights, preferences or
privileges of the shares of Series A, Series B, Series C or Series D Preferred
Stock so as to affect adversely the shares;

               (d)  increase or decrease (other than by redemption or
conversion) the total number of authorized shares of Series A, Series B, Series
C or Series D Preferred Stock provided, however, that the Board of Directors may
amend the terms of any series to decrease the number of shares of that series
(but not below the number of shares of such series then outstanding), and the
number of shares constituting the decrease shall thereafter constitute
authorized but undesignated shares;

               (e)  authorize or issue, or obligate itself to issue, any other
equity security, including any other security convertible into or exercisable
for any equity security having a preference over the Series A, Series B, Series
C or Series D Preferred Stock with respect to voting, or having a preference
over or being on a parity with the Series A, Series B, Series C or Series D
Preferred Stock with respect to dividends or upon liquidation;

                                      -19-
<PAGE>
 
               (f)  enter into any transaction or series of related transactions
in which this Corporation borrows more than $5,000,000;

               (g)  amend this Corporation's Third Amended and Restated
Certificate of Incorporation or Bylaws (excluding an amendment to this
Corporation's Third Amended and Restated Certificate of Incorporation, which
amendment does no more than authorize for issuance an equity security not
covered by subsection 6(e) above);

               (h)  change the authorized number of directors of this
Corporation;

               (i)  pay any dividends on its Common Stock; or

               (j)  redeem, purchase or otherwise acquire (or pay into or set
funds aside for a sinking fund for such purpose) any share or shares of
Preferred Stock or Common Stock; provided, however, that this restriction shall
not apply to the repurchase of shares of Common Stock (up to a maximum of
$500,000) from employees, officers, directors, consultants or other persons
performing services for the Company or any subsidiary.

                      METAWAVE COMMUNICATIONS CORPORATION

                                   ARTICLE I

     2.1  PLACE OF MEETINGS.

     Meetings of stockholders shall be held at any place, within or outside the

such designation, stockholders' meetings shall be held at the registered office
of the corporation.

     2.2  ANNUAL MEETING.

     The annual meeting of stockholders shall be held on such date, time and
place, either within or without the State of Delaware, as may be designated by
resolution of the Board of Directors each year. At the meeting, directors shall

<PAGE>
 
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 as specified in such notice. The officer receiving the request shall cause
notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.5 of this Article II, that a meeting
will be held at the time requested by the person or persons calling the meeting,
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 the
receipt of the request, the person or persons requesting the meeting may give

construed as limiting, fixing, or affecting the time when a meeting of
stockholders called by action of the Board of Directors may be held.

          (c)  Only such business shall be conducted at a special meeting of
stockholders as shall have been brought before the meeting pursuant to the
notice of meeting given in accordance with Section 2.2(b). Nominations of
persons for election to the board of directors may be made at a special meeting

at the meeting and who complies with the notice procedures set forth in Section
2.5.

     2.4  NOTICE OF STOCKHOLDER'S MEETINGS; AFFIDAVIT OF NOTICE.

     All notices of meetings of stockholders shall be in writing and shall be
sent or otherwise given in accordance with this Section 2.4 of these Bylaws not
less than ten (10) nor more than sixty (60) days before the date of the meeting
to each stockholder entitled to vote at such meeting (or such longer or shorter
time as is required by Section 2.5 of these Bylaws, if applicable). The notice
shall specify the place, date, and hour of the meeting, and, in the case of a
special meeting, the purpose or purposes for which the meeting is called.

     Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

     2.5  ADVANCE NOTICE OF STOCKHOLDER 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 stockholders by or at the direction of the board of directors or by
any stockholder 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. 

                                      -2-
<PAGE>
 
To be timely, a stockholder's notice shall be delivered to or mailed and
received at the principal executive offices of the corporation not less than
sixty (60) days nor more than ninety (90) days prior to the meeting; provided,
however, that in the event that less than sixty (60) days' notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder 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
stockholder's notice shall set forth (a) as to each person whom the stockholder
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 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 stockholder giving the notice (i) the name and
address, as they appear on the corporation's books, of such stockholder and (ii)
the class and number of shares of the corporation which are beneficially owned
by such stockholder. 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
stockholder'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  QUORUM.

     The holders of a majority of the stock issued and outstanding and entitled
to vote thereat, present in person or represented by proxy, shall constitute a
quorum at all meetings of the stockholders for the transaction of business
except as otherwise provided by statute or by the certificate of incorporation.
If, however, such quorum is not present or represented at any meeting of the
stockholders, then either (a) the chairman of the meeting or (b) the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented.  At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

     2.7  ADJOURNED MEETING; NOTICE.

     When a meeting is adjourned to another time or place, unless these Bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the 

                                      -3-
<PAGE>
 
corporation may transact any business that might have been transacted at the
original meeting. If the adjournment is for more than thirty (30) days, or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each stockholder of record
entitled to vote at the meeting.

     2.8  CONDUCT OF BUSINESS.

     The chairman of any meeting of stockholders shall determine the order
of business and the procedure at the meeting, including the manner of voting and
the conduct of business.

     2.9  VOTING.

          (a)  The stockholders entitled to vote at any meeting of stockholders
shall be determined in accordance with the provisions of Section 2.11 of these
Bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

          (b)  Except as may be otherwise provided in the certificate of
incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

     2.10  WAIVER OF NOTICE.

     Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these Bylaws.

     2.11  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING.

     In order that the corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof
or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than sixty (60) nor less than ten (10) days before the date of such
meeting, nor more than sixty (60) days prior to any other action. If the Board
of Directors does not so fix a record date:

                                      -4-
<PAGE>
 
          (a)  The record date for determining stockholders entitled to notice
of or to vote at a meeting of stockholders shall be at the close of business on
the day next preceding the day on which notice is given, or, if notice is
waived, at the close of business on the day next preceding the day on which the
meeting is held.

          (b)  The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

      A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     2.12  PROXIES.

     Each stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for such stockholder by a written
proxy, signed by the stockholder and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period. A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact. The revocability of a proxy

annual meeting. Directors need not be stockholders unless so required by the
certificate of incorporation or these Bylaws, wherein other qualifications for
directors may be prescribed. Each director, including a director elected to fill

     Any director may resign at any time upon written notice to the attention of
the Secretary of the corporation. When one or more directors so resigns and the

office, including those who have so resigned, shall have power to fill such
vacancy or vacancies, the vote thereon to take effect when such resignation or
resignations shall become effective, and each director so chosen shall hold
office as provided in this section in the filling of other vacancies. A vacancy
created by the removal of a director by the vote of the stockholders 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 quorum.
Each director so elected shall hold office until the next annual meeting of the
stockholders and until a successor has been elected and qualified.

     Unless otherwise provided in the certificate of incorporation or these
Bylaws:

          (a)  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (b)  Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

     If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

     If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent of the total number of the shares at the time outstanding
having the right to vote for such directors, summarily order an election to be
held to fill any such vacancies or newly created directorships, or to replace
the directors chosen by the directors then in office as aforesaid, which
election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

Board of Directors, may participate in a meeting of the Board of Directors, or
any committee, by means of conference telephone or similar communications

board.

time of the holding of the meeting. If the notice is delivered personally or by
telephone or by 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

     At all meetings of the Board of Directors, a majority of the authorized
number of directors shall constitute a quorum for the transaction of business
and the act of a majority of the directors present at any meeting at which there
is a quorum shall be the act of the Board of Directors, except as may be
otherwise specifically provided by statute or by the certificate of
incorporation. If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

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.

     Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice. Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the directors, or members of a committee of directors, need be specified in
any written waiver of notice unless so required by the certificate of
incorporation or these Bylaws.

     3.10  BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING.

     Unless otherwise restricted by the certificate of incorporation or these
Bylaws, any action required or permitted to be taken at any meeting of the Board
of Directors, or of any committee thereof, may be taken without a meeting if all
members of the board or committee, as the case may be, consent thereto in
writing and the writing or writings are filed with the minutes of proceedings of
the board or committee. Written consents representing actions taken by the board
or committee may be executed by telex, telecopy or other facsimile transmission,
and such facsimile shall be valid and binding to the same extent as if it were
an original.

     3.11  FEES AND COMPENSATION OF DIRECTORS.

     Unless otherwise restricted by the certificate of incorporation or these
Bylaws, the Board of Directors shall have the authority to fix the compensation
of directors. No such compensation shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor.

corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
corporation. The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of

entitled to vote at an election of directors; provided, however, that if the
stockholders of the corporation are entitled to cumulative voting, if less than

without cause if the votes cast against his removal would be sufficient to elect
him if then cumulatively voted at an election of the entire Board of Directors.

     No reduction of the authorized number of directors shall have the effect of
removing any director prior to the expiration of such director's term of office.

into, or the exchange of such shares for, shares of any other class or classes
or any other series of the same or any other class or classes of stock of the

officers against expenses (including attorneys' fees), judgments, fines,
settlements and other amounts actually and reasonably incurred in connection

manner permitted by the General Corporation Law of Delaware, to indemnify each
of its employees and agents (other than directors and officers) against expenses

actually and reasonably incurred in connection with any proceeding, arising by
reason of the fact that such person is or was an agent of the corporation. For

agent of the corporation, (b) 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 (c) who was an employee or agent of a
corporation which was a predecessor corporation of the corporation or of another
enterprise at the request of such predecessor corporation.

     6.3  PAYMENT OF EXPENSES IN ADVANCE.

     Expenses incurred in defending any 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

disposition of such action or proceeding upon receipt of an undertaking by or on

                                      -14-
<PAGE>
 
be determined that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     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 certificate of
incorporation.

employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,

against such liability under the provisions of the General Corporation Law of
Delaware.

     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:

          (a)  That it would be inconsistent with a provision of the certificate
of incorporation, these Bylaws, a resolution of the stockholders 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

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

business.

Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought. The Court may summarily order the
corporation to permit the director to inspect any and all books and records, the
stock ledger, and the stock list and to make copies or extracts therefrom. The
Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

                                  ARTICLE VIII

                                GENERAL MATTERS

     8.1  CHECKS.

     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.

     8.2  EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS.

     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

                                      -16-
<PAGE>
 
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.

     8.3  STOCK CERTIFICATES; PARTLY PAID SHARES.

     The shares of a corporation shall be represented by certificates, provided
that the Board of Directors of the corporation may provide by resolution or
resolutions that some or all of any or all classes or series of its stock shall
be uncertificated shares. Any such resolution shall not apply to shares
represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the Board of
Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the corporation by the chairman or vice-chairman of
the Board of Directors, or the chief executive officer or the president or vice-
president, and by the chief financial officer or an assistant treasurer, or the
secretary or an assistant secretary of such corporation representing the number
of shares registered in certificate form. Any or all of the signatures on the
certificate may be a facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
has ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the corporation with the same effect
as if he or she were such officer, transfer agent or registrar at the date of
issue.

     The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

     8.4  SPECIAL DESIGNATION ON CERTIFICATES.

     If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

                                     -17-
<PAGE>
 
     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 corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate previously issued by it, alleged to have been lost, stolen or
destroyed, and the corporation may require the owner of the lost, stolen or
destroyed certificate, or the owner's legal representative, to give the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate or uncertificated shares.

     8.6  CONSTRUCTION; DEFINITIONS.

     Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Delaware General Corporation Law 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.

     8.7  DIVIDENDS.

     The directors of the corporation, subject to any restrictions contained in
(a) the General Corporation Law of Delaware or (b) the certificate of
incorporation, may declare and pay dividends upon the shares of its capital
stock. Dividends may be paid in cash, in property, or in shares of the
corporation's capital stock.

     The directors of the corporation may set apart out of any of the funds of
the corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve. Such purposes shall include but not be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

     8.8  FISCAL YEAR.

     The fiscal year of the corporation shall be fixed by resolution of the
Board of Directors and may be changed by the Board of Directors.

     8.9  SEAL.

     The corporation may adopt a corporate seal, which may be altered at
pleasure, and may use the same by causing it or a facsimile thereof, to be
impressed or affixed or in any other manner reproduced.

     8.10  TRANSFER OF STOCK.

     Upon surrender to the corporation or the transfer agent of the corporation
of a certificate for shares duly endorsed or accompanied by proper evidence of
succession, 

                                      -18-
<PAGE>
 
assignation or authority to transfer, it shall be the duty of the corporation to
issue a new certificate to the person entitled thereto, cancel the old
certificate, and record the transaction in its books.

     8.11  STOCK TRANSFER AGREEMENTS.

     The corporation shall have power to enter into and perform any agreement
with any number of stockholders of any one or more classes of stock of the
corporation to restrict the transfer of shares of stock of the corporation of
any one or more classes owned by such stockholders in any manner not prohibited
by the General Corporation Law of Delaware.

     8.12  REGISTERED STOCKHOLDERS.

     The corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                  ARTICLE IX

                                  AMENDMENTS

     The Bylaws of the corporation may be adopted, amended or repealed by
the stockholders entitled to vote; provided, however, that the corporation may,
in its certificate of incorporation, confer the power to adopt, amend or repeal
Bylaws upon the directors; provided, further, any amendment to the Bylaws that
increases or reduces the authorized number of directors shall require the
affirmative approval of at least two-thirds of the directors.  The fact that
such power has been so conferred upon the directors shall not divest the
stockholders of the power, nor limit their power to adopt, amend or repeal
Bylaws.  Notwithstanding the foregoing, any amendments to this Article IX shall
require approval of holders of two-thirds of the outstanding Common Stock.

     The undersigned hereby certifies that the undersigned is the duly elected,

1998, by the Board of Directors of the corporation.

                                                                    EXHIBIT 10.1

                           INDEMNIFICATION AGREEMENT

     This Indemnification Agreement (the "Agreement") is made as of
_______________, by and between Metawave Communications Corporation, a Delaware
corporation (the "Company"), and [IndemniteeName] (the "Indemnitee").

                                   RECITALS

     The Company and Indemnitee recognize the increasing difficulty in obtaining
liability insurance for directors, officers and key employees, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance.  The Company and Indemnitee further recognize the
substantial increase in corporate litigation in general, subjecting directors,
officers and key employees to expensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely limited.
Indemnitee does not regard the current protection available as adequate under
the present circumstances, and Indemnitee and agents of the Company may not be
willing to continue to serve as agents of the Company without additional
protection.  The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, and to indemnify its directors,
officers and key employees so as to provide them with the maximum protection
permitted by law.

                                   AGREEMENT

     In consideration of the mutual promises made in this Agreement, and for
other good and valuable consideration, receipt of which is hereby acknowledged,
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
<PAGE>
 
reasonably believed to be in or not opposed to the best interests of
the Company, or, with respect to any criminal action or proceeding, that
Indemnitee had reasonable cause to believe that Indemnitee's 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 proceeding 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 (if such settlement is approved in advance by
the Company, which approval shall not be unreasonably withheld), 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 stockholders, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which Indemnitee shall have been finally adjudicated by court order or judgment
to be liable to the Company in the performance of Indemnitee's duty to the
Company and its stockholders unless and only to the extent that the court in
which such action or proceeding 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 such expenses which such court
shall deem proper.

          (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 Section 1(a) or Section 1(b) 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.   NO EMPLOYMENT RIGHTS.  Nothing contained in this Agreement is intended
to create in Indemnitee any right to continued employment.

     3.   EXPENSES; INDEMNIFICATION PROCEDURE.

          (a)  ADVANCEMENT OF EXPENSES.  The Company shall advance all expenses
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action, suit or proceeding referred to in
Section l(a) or Section 1(b) hereof (including 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.

          (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

                                      -2-
<PAGE>
 
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 and
shall be given in accordance with the provisions of Section 12(d) below. 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 and this Section 3 shall be made no later than twenty (20) 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 Certificate of
Incorporation or Bylaws providing for indemnification, is not paid in full by
the Company within twenty (20) 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 11 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, but the burden of
proving such defense shall be on the Company and Indemnitee shall be entitled to
receive interim payments of expenses pursuant to Section 3(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
stockholders) 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 stockholders) 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 3(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 3(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

                                      -3-
<PAGE>
 
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 counsel in any such proceeding at Indemnitee's expense; and (ii)
if (A) the employment of counsel by Indemnitee has been previously 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.

     4.   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 Certificate
of Incorporation, the Company's Bylaws or by statute. In the event of any
change, after the date of this Agreement, in any applicable law, statute, or
rule which expands the right of a Delaware corporation to indemnify a member of
its board of directors or an officer, such changes shall be deemed to be within
the purview of Indemnitee's rights and the Company's obligations under this
Agreement. In the event of any change in any applicable law, statute or rule
which narrows the right of a Delaware 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 Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested members of the Company's Board of
Directors, the General Corporation Law of the State of Delaware, 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 any such capacity at the time of any action, suit or other covered
proceeding.

     5.   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 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.

     6.   MUTUAL ACKNOWLEDGMENT.  Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or public policy may override applicable
state law and prohibit the Company from indemnifying its directors and officers
under this Agreement or otherwise.

                                      -4-
<PAGE>
 
For example, the Company and Indemnitee acknowledge that the Securities and
Exchange Commission (the "SEC") has taken the position that indemnification is
not permissible for liabilities arising under certain federal securities laws,
and federal legislation prohibits indemnification for certain ERISA violations.
Indemnitee understands and acknowledges that the Company has undertaken or may
be required in the future to undertake with the SEC 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.

     7.   OFFICER AND DIRECTOR LIABILITY INSURANCE.  The Company shall, 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
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 parent
or subsidiary of the Company.

     8.   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 8. 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.

     9.   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 145 of the Delaware General Corporation Law, but such indemnification or

                                      -5-
<PAGE>
 
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors finds it to be appropriate;

          (b)  LACK OF GOOD FAITH.  To indemnify Indemnitee for any expenses
incurred by 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 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) to the
extent such expenses or liabilities have been paid directly to Indemnitee by an
insurance carrier under a policy of officers' and directors' liability insurance
maintained by the Company; or

          (d)  CLAIMS UNDER SECTION 16(b).  To indemnify Indemnitee for expenses
or 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.

     10.  CONSTRUCTION OF CERTAIN PHRASES.

          (a)  For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, 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.

     11.  ATTORNEYS' FEES.  In the event that any action is instituted by
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

                                      -6-
<PAGE>
 
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

                      METAWAVE COMMUNICATIONS CORPORATION

               THIRD AMENDED AND RESTATED 1995 STOCK OPTION PLAN

grant of an option and subject to the applicable provisions of Section 422 of

market trading day prior to the time of determination, as reported in The Wall
Street Journal or such other source as the Administrator deems reliable; or

               (iii) In the absence of an established market for the Common

the Plan, the maximum aggregate number of shares that may be optioned and sold
under the Plan is 4,150,000 shares of Common Stock. The shares may be
authorized, but unissued, or reacquired Common Stock. If an Option should expire
or become unexercisable for any reason without having been exercised in full,
the unpurchased Shares that were subject thereto shall, unless the Plan shall
have been terminated, become available for future grant under the Plan. In
addition, any shares of Common Stock which are retained by the Company upon
exercise of an Option in order to satisfy the exercise or purchase price for
such Option or any withholding taxes due with respect to such exercise shall be

                                      -4-
<PAGE>
 
          (b)  Plan Procedure After the Date, if any, Upon Which the Company
Becomes Subject to the Exchange Act.

               (i)   Multiple Administrative Bodies.  If permitted by Rule 16b-
3, grants under the Plan may be made by different bodies with respect to
directors, non-director officers and Employees or Consultants who are not
Reporting Persons.

               (ii)  Administration With Respect to Reporting Persons.  With
respect to grants of Options to Employees who are Reporting Persons, such grants
shall be made by (A) the Board if the Board may make grants to Reporting Persons
under the Plan in compliance with Rule 16b-3 and Section 162(m) of the Code as
it applies so as to qualify grants of options to Named Executive Officers as
performance-based compensation, or (B) a committee designated by the Board to
make grants to Reporting Persons under the Plan, which committee shall be
constituted in such a manner as to permit grants under the Plan to comply with
Rule 16b-3 and to qualify grants of Options to Named Executives as performance-
based compensation under Section 162(m) of the Code and otherwise so as to
satisfy the Applicable Laws. Once appointed, 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 the 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 the committee and thereafter directly make grants to Reporting
Persons under the Plan, all to the extent permitted by Rule 16b-3.

               (iii) Administration With Respect to Consultants and Other
Employees. With respect to grants of Options to Employees or Consultants who are
not Reporting Persons, the Plan shall be administered by (A) the Board or (B) a
committee designated by the Board, which committee shall be constituted in such
a manner as to satisfy the legal requirements relating to the administration of
incentive stock option plans, if any, of applicable corporate and securities
laws, of the Code and of any applicable Stock Exchange (the "Applicable Laws").
Once appointed, 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 the 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 the
Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

          (c)  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:

               (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 hereunder;

                                      -5-
<PAGE>
 
               (iii) to determine whether and to what extent Options or any
combination thereof are granted hereunder;

               (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;

               (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 shall have declined since the date the Option was granted;

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

               (x)   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.

          (d)  Effect of Administrator's Decision. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
holders of Options.

     5.   ELIGIBILITY.

          (a)  Recipients of Grants.  Nonstatutory Stock Options may be granted
to Employees and Consultants. Incentive Stock Options may be granted only to
Employees; provided, however, that Employees of an Affiliate 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 written
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 the 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.

                                      -6-
<PAGE>
 
          (c)  Employment Relationship.  The Plan shall not confer upon any
Optionee 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 the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company as described in Section 19 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 15 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
(10) 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, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

     8.   LIMITATION ON GRANTS TO EMPLOYEES.  Subject to adjustment as provided
in this Plan, the maximum number of Shares which may be subject to options
granted to any one Employee under this Plan for any fiscal year of the Company
shall be [250,000]. This Section 8 shall not apply prior to the date upon which
the Company becomes subject to the Exchange Act and following such date, shall
not apply until the (i) earliest of: (A) the first material modification of the
Plan (including any increase to the number of shares reserved for issuance under
the Plan in accordance with Section 3); (B) the issuance of all of the shares of
common stock reserved for issuance under the Plan; (C) the expiration of the
Plan; or (D) the first meeting of shareholders at which directors are to be
elected that occurs after the close of the third calendar year following the
calendar year in which occurred the first registration of any equity security
under Section 12 of the Exchange Act; or (ii) such other date required by
Section 162(m) of the Code and the rules and regulations promulgated thereunder.

     9.   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 Board, 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 the grant of
such Incentive Stock Option, owns stock representing more than ten percent (10%)
of the total combined voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant.

                                      -7-
<PAGE>
 
                    (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.

               (ii) In the case of a Nonstatutory Stock Option that is:

                    (A)  granted to a person who, at the time of the grant of
such Option, is a Named Executive Officer the per Share exercise price shall be
no less than 100% of the Fair Market Value per Share on the date of the grant.

                    (B)  granted to any person other than a Named Executive
Officer, the per Share exercise price shall be no less than 85% of the Fair
Market Value per Share on the date of grant.

          (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) promissory note (subject to the provisions of Section 153 of the
Delaware General Corporation Law), (4) other Shares that (x) in the case of
Shares acquired upon exercise of an Option, 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 [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, (5) 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, (6) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price and any applicable
income or employment taxes, (7) any combination of the foregoing methods of
payment, or (8) such other consideration and method of payment for the issuance
of Shares to the extent permitted under 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.

     10.  EXERCISE OF OPTION.

          (a)  Procedure for Exercise; Rights as a Stockholder.  Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

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

               An Option shall be deemed to be 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

                                      -8-
<PAGE>
 
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 9(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 stockholder 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 12 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.  Subject to
Section 10(c), in the event of termination of an Optionee's Continuous Status as
an Employee or Consultant with the Company, such Optionee may, but only within
three (3) months (or such other period of time not less than thirty (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 and not
exceeding three (3) months) 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
Optionee was not entitled to exercise the Option at the date of such
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.  No
termination shall be deemed to occur and this Section 10(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 10(b) above, in the event of
termination of an Optionee's Continuous Status as an Employee or Consultant as a
result of his or her total and permanent disability (within the meaning of
Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months
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 Optionee was not entitled to exercise the Option
at the date of termination, or if Optionee does not exercise such Option to the
extent so entitled within the time specified herein, the Option shall terminate.

               (ii) In the event of termination of an Optionee's Continuous
Status as an Employee or Consultant 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), Optionee may, but only within six (6) months 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

                                      -9-
<PAGE>
 
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 which is an Incentive Stock Option ("ISO") (within the meaning of Section
422 of the Code) within three (3) months of the date of such termination, the
Option will not qualify for ISO treatment under the Code. To the extent that
Optionee was not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within six
months (6) from the date of termination, the Option shall terminate.

          (d)  Death of Optionee.  In the event of the death of an Optionee
during the period of Continuous Status as an Employee or Consultant since the
date of grant of the Option, or within thirty (30) days following termination of
Optionee's Continuous Status as an Employee or Consultant, the Option may be
exercised, at any time within six (6) 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 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 Optionee's Continuous Status as an Employee or
Consultant. To the extent that Optionee was not entitled to exercise the Option
at the date of death or termination, as the case may be, or if Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate.

          (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 10(b), 10(c)
and 10(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)  Termination for Misconduct.  Notwithstanding Sections 10(b), (c),
(d) and (e) above, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant for Misconduct, all outstanding Options held
by the Optionee shall terminate immediately and cease to be outstanding. For
purposes of this Section 10(f), Misconduct shall mean the commission of any act
of fraud, embezzlement or dishonesty by the Optionee, any unauthorized use or
disclosure by such person of confidential information or trade secrets of the
Company or any Parent or Subsidiary, or any other intentional misconduct by such
person adversely affecting the business or affairs of the Company or any Parent
or Subsidiary in a material manner.

          (g)  Rule 16b-3.  Options granted to Reporting Persons shall comply
with Rule 16b-3 and shall contain such additional conditions or restrictions as
may be required thereunder to qualify for the maximum exemption for Plan
transactions.

          (h)  Buyout Provisions.  The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted, based on
such terms and

                                      -10-
<PAGE>
 
conditions as the Administrator shall establish and communicate to the Optionee
at the time that such offer is made.

     11.  WITHHOLDING TAXES.  As a condition to the exercise of Options granted
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with the exercise, receipt or
vesting of such Option. The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

     12.  STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph. When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods: (a) by cash payment, or (b) out of Optionee's current
compensation, (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than the applicable taxes on the ordinary income
recognized or (d) by electing to have the Company withhold from the Shares to be
issued upon exercise of the Option, if any, that number of Shares having a fair
market value equal to the amount required to be withheld. For this purpose, 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 (the "Tax Date").

          Any surrender by a Reporting Person of previously owned Shares to
satisfy tax withholding obligations arising upon exercise of this Option must
comply with the applicable provisions of Rule 16b-3.

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

          In the event the election to have Shares withheld is made by an
Optionee 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 Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

                                      -11-
<PAGE>
 
     13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR CERTAIN OTHER
TRANSACTIONS.

          (a)  Changes in Capitalization.  Subject to any required action by the
stockholders 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, the maximum number of shares of Common Stock for which Options may
be granted to any employee under Section 8 of the Plan, 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,
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 Board, whose determination in that respect shall be final,
binding and 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 proposed
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action. To the extent it has
not been previously exercised, the Option will terminate immediately prior to
the consummation of such proposed action.

          (c)  Control Transaction

               (i)   The Company shall provide each Optionee with notice of the
pendency of any Control Transaction (i) at least thirty (30) days prior to the
expected date of consummation of a Control Transaction that has been approved or
recommended by the Board, or (ii) promptly after the Board becomes aware of the
pendency or occurrence of a proposed or completed Control Transaction that has
not been approved or recommended by the Board.

               (ii)  Each Optionee shall be entitled to exercise the vested
portion of the Option at any time prior to consummation of a Control
Transaction. If the terms of the Option prescribe a time-based vesting schedule,
the Optionee shall, conditioned upon consummation of the Control Transaction and
upon the Optionee remaining employed by the Company through the date of such
consummation, be entitled to accelerated vesting credit equal to either twelve
months or twenty-four months of additional vesting beyond that otherwise
scheduled, based on whether he or she has been employed by the Company less than
two years, or two years or more, respectively, as of the date of such
consummation; provided, however, that this sentence shall not apply with respect
to any Option as to which the Administrator determines, in its sole discretion,
that the Board or the acquiring person or the surviving corporation, as the case
may be, has made

                                      -12-
<PAGE>
 
equitable and appropriate provision for the assumption of or the substitution of
a new option for the Option on terms which are, as nearly as practicable, the
financial equivalent of the Option (taking into account the consideration for
which the Common Stock is to be exchanged in the Control Transaction).

               (iii) Any exercise may be made contingent upon consummation of a
Control Transaction if so elected by the Optionee in his or her notice of
exercise, and must be made contingent upon such consummation with respect to any
portion of an Option entitled to accelerated vesting under the second sentence
of Section 13(c)(ii) above.

               (iv)  Upon consummation of a Control Transaction that has been
approved or recommended by the Board, all unexercised Options shall expire,
except to the extent that the Administrator determines otherwise pursuant to the
second sentence of Section 13(c)(ii) above.

          (d)  Certain Distributions.  In the event of any distribution to the
Company's stockholders 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.

     14.  NON-TRANSFERABILITY OF OPTIONS.  Options 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 and may be exercised or purchased
during the lifetime of the Optionee only by the Optionee. The designation of a
beneficiary by an Optionee will not constitute transfer.

     15.  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 Board; 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.

     16.  AMENDMENT AND TERMINATION OF THE PLAN.

          (a)  Authority to Amend or Terminate.  The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made that would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 or
with Sections 162(m) and 422 of the Code (or any other applicable law or
regulation, including the requirements of any Stock Exchange), the Company shall
obtain stockholder approval of any Plan amendment in such a manner and to such a
degree as required.

                                      -13-
<PAGE>
 
          (b)  Effect of Amendment or Termination.  No amendment or termination
of the Plan shall adversely affect Options already granted, unless mutually
agreed otherwise between the Optionee and the Board, which agreement must be in
writing and signed by the Optionee and the Company.

     17.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any Stock Exchange and shall be further
subject to the approval of counsel to 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 law.

     18.  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.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     19.  AGREEMENTS.  Options shall be evidenced by written agreements in such
form as the Administrator shall approve from time to time.

     20.  STOCKHOLDER APPROVAL.

          (a)  Continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months before or after the date
the Plan is adopted. Such stockholder approval shall be obtained in the degree
and manner required under applicable state and federal law and the rules of any
Stock Exchange upon which the Common Stock is listed. All Options issued under
the Plan shall become void in the event such approval is not obtained.

          (b)  In the event that the Company registers any class of equity
securities pursuant to Section 12 of the Exchange Act, any required approval of
the stockholders of the Company obtained after such registration shall be
solicited substantially in accordance with Section 14(a) of the Exchange Act and
the rules and regulations promulgated thereunder.

          (c)  If any required approval by the stockholders of the Plan itself
or of any amendment thereto is solicited at any time otherwise than in the
manner described in Section 20(b) hereof, then the Company shall, at or prior to
the first annual meeting of stockholders held subsequent to the later of (1) the
first registration of any class of equity

                                      -14-
<PAGE>
 
securities of the Company under Section 12 of the Exchange Act or (2) the
granting of an Option hereunder to an officer or director after such
registration, do the following:

               (i)  furnish in writing to the holders entitled to vote for the
Plan substantially the same information that would be required (if proxies to be
voted with respect to approval or disapproval of the Plan or amendment were then
being solicited) by the rules and regulations in effect under Section 14(a) of
the Exchange Act at the time such information is furnished; and

               (ii) file with, or mail for filing to, the Securities and
Exchange Commission four copies of the written information referred to in
subsection (i) hereof not later than the date on which such information is first
sent or given to stockholders.

exchange or a national market system including without limitation the National
Market of the National Association of Securities Dealers, Inc. Automated
Quotation ("NASDAQ") System, its Fair Market Value shall be the closing sales
            ------
price for such stock (or the closing bid, if no sales were reported), as quoted
on such system or exchange, or the exchange with the greatest volume of trading
in Common Stock for the last market trading day prior to the time of
determination, as reported in The Wall Street Journal or such other source as
the Administrator deems reliable;

               (ii)  If the Common Stock is quoted on the NASDAQ System (but not
on the National Market thereof) or regularly quoted by a recognized securities

     4.   ADMINISTRATION OF THE PLAN.
          -------------------------- 

          (a)  Initial Plan Procedure.  Prior to the date, if any, upon which
               ----------------------
the Company becomes subject to the Exchange Act, the Plan shall be administered
by the Board or a committee appointed by the Board.

          (b)  Plan Procedure After the Date, if any, Upon Which the Company
               -------------------------------------------------------------
Becomes Subject to the Exchange Act.
- ----------------------------------- 

               (i)   Multiple Administrative Bodies.  If permitted by Rule 16b-
                     ------------------------------
3, grants under the Plan may be made by different bodies with respect to
directors, non-director officers and Employees or Consultants who are not
Reporting Persons.

               (ii)  Administration With Respect to Reporting Persons. With
                     ------------------------------------------------
respect to grants of Options to Employees who are Reporting Persons, such grants
shall be made by (A) the Board if the Board may make grants to Reporting Persons
under the Plan in compliance with Rule 16b-3 and Section 162(m) of the Code as
it applies so as to qualify grants of options to Named Executive Officers as
performance-based compensation, or (B) a committee designated by the Board to
make grants to Reporting Persons under the Plan, which committee shall be
constituted in such a manner as to permit grants under the Plan to comply with
Rule 16b-3 and to qualify grants of Options to Named Executives as performance-
based compensation under Section 162(m) of the Code and otherwise so as to
satisfy the Applicable Laws. Once appointed, 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 the 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 the committee and thereafter directly make grants to Reporting
Persons under the Plan, all to the extent permitted by Rule 16b-3.

               (iii) Administration With Respect to Consultants and Other
                     ----------------------------------------------------
Employees.  With respect to grants of Options to Employees or Consultants who
- ---------
are not Reporting Persons, the Plan shall be administered by (A) the Board or
(B) a committee designated by the Board, which committee shall be constituted in
such a manner as to satisfy the legal requirements relating to the
administration of incentive stock option plans, if any, of applicable corporate
and securities laws, of the Code and of any applicable Stock Exchange (the
"Applicable Laws").  Once appointed, 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 the 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 the Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.

          (c)  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:

                                      -5-
<PAGE>
 
               (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 hereunder;

               (iii)  to determine whether and to what extent Options or any
combination thereof are granted hereunder;

               (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;

               (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 shall have declined since the date the Option was granted;

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

               (x)    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.

          (d)  Effect of Administrator's Decision. All decisions, determinations
               ----------------------------------
and interpretations of the Administrator shall be final and binding on all
holders of Options.

     5.   ELIGIBILITY.
          ----------- 

          (a)  Recipients of Grants.  Nonstatutory Stock Options may be granted
               --------------------
to Employees and Consultants.  Incentive Stock Options may be granted only to
Employees; provided, however, that Employees of an Affiliate 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 written
               --------------
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 the Shares with respect to which Options
designated as Incentive Stock Options are exercisable for 

                                      -6-
<PAGE>
 
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)  Employment Relationship.  The Plan shall not confer upon any
               -----------------------
Optionee 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 the earlier to
          ------------
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company as described in Section 19 of the Plan.  It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 15 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
(10) 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, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

     8.   LIMITATION ON GRANTS TO EMPLOYEES.  Subject to adjustment as provided
          ---------------------------------
in this Plan, the maximum number of Shares which may be subject to options
granted to any one Employee under this Plan for any fiscal year of the Company
shall be [5,000,000 MINUS 1995 PLAN OUTSTANDING OPTIONS AS OF S-1 EFFECTIVE
DATE]. This Section 8 shall not apply prior to the date upon which the Company
becomes subject to the Exchange Act and following such date, shall not apply
until the (i) earliest of:  (A) the first material modification of the Plan
(including any increase to the number of shares reserved for issuance under the
Plan in accordance with Section 3); (B) the issuance of all of the shares of
common stock reserved for issuance under the Plan; (C) the expiration of the
Plan; or (D) the first meeting of shareholders at which directors are to be
elected that occurs after the close of the third calendar year following the
calendar year in which occurred the first registration of any equity security
under Section 12 of the Exchange Act; or (ii) such other date required by
Section 162(m) of the Code and the rules and regulations promulgated thereunder.

     9.   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 Board, but
shall be subject to the following:

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

                                      -7-
<PAGE>
 
                    (A)  granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns stock representing more than ten percent (10%)
of the total combined voting power of all classes of stock of the Company or any
Parent or Subsidiary, 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.

               (ii) In the case of a Nonstatutory Stock Option that is:

                    (A)  granted to a person who, at the time of the grant of
such Option, is a Named Executive Officer the per Share exercise price shall be
no less than 100% of the Fair Market Value per Share on the date of the grant.

                    (B)  granted to any person other than a Named Executive
Officer, the per Share exercise price shall be no less than 85% of the Fair
Market Value per Share on the date of grant.

          (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) promissory note (subject to the provisions of Section 153 of the
Delaware General Corporation Law), (4) other Shares that (x) in the case of
Shares acquired upon exercise of an Option, 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 [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, (5) 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, (6) delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price and any applicable
income or employment taxes, (7) any combination of the foregoing methods of
payment, or (8) such other consideration and method of payment for the issuance
of Shares to the extent permitted under 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.

     10.  EXERCISE OF OPTION.
          ------------------ 

          (a)  Procedure for Exercise; Rights as a Stockholder.  Any Option
               -----------------------------------------------
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

                                      -8-
<PAGE>
 
               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be 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 9(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 stockholder 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 12 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.  Subject to
               ----------------------------------------------------
Section 10(c), in the event of termination of an Optionee's Continuous Status as
an Employee or Consultant with the Company, such Optionee may, but only within
three (3) months (or such other period of time not less than thirty (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 and not
exceeding three (3) months) 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
Optionee was not entitled to exercise the Option at the date of such
termination, or if Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.  No
termination shall be deemed to occur and this Section 10(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 10(b) above, in the event of
termination of an Optionee's Continuous Status as an Employee or Consultant as a
result of his or her total and permanent disability (within the meaning of
Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months
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 Optionee was not entitled to exercise the Option
at the date of termination, or if Optionee does not exercise such Option to the
extent so entitled within the time specified herein, the Option shall terminate.

                                      -9-
<PAGE>
 
               (ii)  In the event of termination of an Optionee's Continuous
Status as an Employee or Consultant 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), Optionee may, but only within six (6) months 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 which is an Incentive Stock Option ("ISO") (within the meaning of Section
422 of the Code) within three (3) months of the date of such termination, the
Option will not qualify for ISO treatment under the Code. To the extent that
Optionee was not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within six
months (6) from the date of termination, the Option shall terminate.

          (d)  Death of Optionee.  In the event of the death of an Optionee
               -----------------
during the period of Continuous Status as an Employee or Consultant since the
date of grant of the Option, or within thirty (30) days following termination of
Optionee's Continuous Status as an Employee or Consultant, the Option may be
exercised, at any time within six (6) 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 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 Optionee's Continuous Status as an Employee or
Consultant.  To the extent that Optionee was not entitled to exercise the Option
at the date of death or termination, as the case may be, or if Optionee does not
exercise such Option to the extent so entitled within the time specified herein,
the Option shall terminate.

          (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 10(b), 10(c)
and 10(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)  Termination for Misconduct.  Notwithstanding Sections 10(b), (c),
               --------------------------
(d) and (e) above, in the event of termination of an Optionee's Continuous
Status as an Employee or Consultant for Misconduct, all outstanding Options held
by the Optionee shall terminate immediately and cease to be outstanding.  For
purposes of this Section 10(f), Misconduct shall mean the commission of any act
of fraud, embezzlement or dishonesty by the Optionee, any unauthorized use or
disclosure by such person of confidential information or trade secrets of the
Company or any Parent or Subsidiary, or any other intentional misconduct by such
person adversely affecting the business or affairs of the Company or any Parent
or Subsidiary in a material manner.

                                      -10-

          (g)  Rule 16b-3.  Options granted to Reporting Persons shall comply
               ----------
with Rule 16b-3 and shall contain such additional conditions or restrictions as
may be required thereunder to qualify for the maximum exemption for Plan
transactions.

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

     11.  WITHHOLDING TAXES.  As a condition to the exercise of Options granted
          -----------------
hereunder, the Optionee shall make such arrangements as the Administrator may
require for the satisfaction of any federal, state, local or foreign withholding
tax obligations that may arise in connection with the exercise, receipt or
vesting of such Option.  The Company shall not be required to issue any Shares
under the Plan until such obligations are satisfied.

     12.  STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS.  At the
          --------------------------------------------------------
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this paragraph.  When an Optionee incurs tax liability in
connection with an Option, which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by one or some combination of the
following methods:  (a) by cash payment, or (b) out of Optionee's current
compensation, (c) if permitted by the Administrator, in its discretion, by
surrendering to the Company Shares that (i) in the case of Shares previously
acquired from the Company, have been owned by the Optionee for more than six
months on the date of surrender, and (ii) have a fair market value on the date
of surrender equal to or less than the applicable taxes on the ordinary income
recognized or (d) by electing to have the Company withhold from the Shares to be
issued upon exercise of the Option, if any, that number of Shares having a fair
market value equal to the amount required to be withheld.  For this purpose, 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 (the "Tax Date").
                                                                --------

          Any surrender by a Reporting Person of previously owned Shares to
satisfy tax withholding obligations arising upon exercise of this Option must
comply with the applicable provisions of Rule 16b-3.

          All elections by an Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made; and

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

                                      -11-
<PAGE>
 
          In the event the election to have Shares withheld is made by an
Optionee 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 Optionee shall receive
the full number of Shares with respect to which the Option is exercised but such
Optionee shall be unconditionally obligated to tender back to the Company the
proper number of Shares on the Tax Date.

     13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR CERTAIN OTHER
          -------------------------------------------------------------------
TRANSACTIONS.
- ------------ 

          (a)  Changes in Capitalization.  Subject to any required action by the
               -------------------------
stockholders 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, the maximum number of shares of Common Stock for which Options may
be granted to any employee under Section 8 of the Plan, 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,
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 Board, whose determination in that respect shall be final,
binding and 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 proposed
               --------------------------
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action.  To the extent it has
not been previously exercised, the Option will terminate immediately prior to
the consummation of such proposed action.

          (c)  Control Transaction
               -------------------

               (i)  The Company shall provide each Optionee with notice of the
pendency of any Control Transaction (i) at least thirty (30) days prior to the
expected date of consummation of a Control Transaction that has been approved or
recommended by the Board, or (ii) promptly after the Board becomes aware of the
pendency or occurrence of a proposed or completed Control Transaction that has
not been approved or recommended by the Board.

               (ii) Each Optionee shall be entitled to exercise the vested
portion of the Option at any time prior to consummation of a Control
Transaction. If the terms of the Option prescribe a time-based vesting schedule,
the Optionee shall, conditioned upon consummation of the Control Transaction and
upon the Optionee remaining employed by the Company through the date of such
consummation, be entitled to accelerated vesting credit equal to either twelve

                                      -12-
<PAGE>
 
months or twenty-four months of additional vesting beyond that otherwise
scheduled, based on whether he or she has been employed by the Company less than
two years, or two years or more, respectively, as of the date of such
consummation; provided, however, that this sentence shall not apply with respect
to any Option as to which the Administrator determines, in its sole discretion,
that the Board or the acquiring person or the surviving corporation, as the case
may be, has made equitable and appropriate provision for the assumption of or
the substitution of a new option for the Option on terms which are, as nearly as
practicable, the financial equivalent of the Option (taking into account the
consideration for which the Common Stock is to be exchanged in the Control
Transaction).

               (iii) Any exercise may be made contingent upon consummation of a
Control Transaction if so elected by the Optionee in his or her notice of
exercise, and must be made contingent upon such consummation with respect to any
portion of an Option entitled to accelerated vesting under the second sentence
of Section 13(c)(ii) above.

               (iv)  Upon consummation of a Control Transaction that has been
approved or recommended by the Board, all unexercised Options shall expire,
except to the extent that the Administrator determines otherwise pursuant to the
second sentence of Section 13(c)(ii) above.

          (d)  Certain Distributions.  In the event of any distribution to the
               ---------------------
Company's stockholders 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.

     14.  NON-TRANSFERABILITY OF OPTIONS.  Options 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 and may be exercised or purchased
during the lifetime of the Optionee only by the Optionee.  The designation of a
beneficiary by an Optionee will not constitute transfer.

     15.  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 Board; 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.

     16.  AMENDMENT AND TERMINATION OF THE PLAN.
          ------------------------------------- 

          (a)  Authority to Amend or Terminate.  The Board may at any time
               -------------------------------
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made that would impair the rights of any
Optionee under any grant theretofore 

                                      -13-
<PAGE>
 
made, without his or her consent. In addition, to the extent necessary and
desirable to comply with Rule 16b-3 or with Sections 162(m) and 422 of the Code
(or any other applicable law or regulation, including the requirements of any
Stock Exchange), the Company shall obtain stockholder 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 adversely affect Options already granted, unless mutually
agreed otherwise between the Optionee and the Board, which agreement must be in
writing and signed by the Optionee and the Company.

     17.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
          ----------------------------------
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any Stock Exchange and shall be further
subject to the approval of counsel to 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 law.

     18.  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.  The inability of the
Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

     19.  AGREEMENTS.  Options shall be evidenced by written agreements in such
          ----------
form as the Administrator shall approve from time to time.

     20.  STOCKHOLDER APPROVAL.
          -------------------- 

          (a)  Continuance of the Plan shall be subject to approval by the
stockholders of the Company within twelve (12) months before or after the date
the Plan is adopted.  Such stockholder approval shall be obtained in the degree
and manner required under applicable state and federal law and the rules of any
Stock Exchange upon which the Common Stock is listed.  All Options issued under
the Plan shall become void in the event such approval is not obtained.

          (b)  In the event that the Company registers any class of equity
securities pursuant to Section 12 of the Exchange Act, any required approval of
the stockholders of the Company obtained after such registration shall be
solicited substantially in accordance with Section 14(a) of the Exchange Act and
the rules and regulations promulgated thereunder.

                                      -14-
<PAGE>
 
          (c)  If any required approval by the stockholders of the Plan itself
or of any amendment thereto is solicited at any time otherwise than in the
manner described in Section 20(b) hereof, then the Company shall, at or prior to
the first annual meeting of stockholders held subsequent to the later of (1) the
first registration of any class of equity securities of the Company under
Section 12 of the Exchange Act or (2) the granting of an Option hereunder to an
officer or director after such registration, do the following:

               (i)   furnish in writing to the holders entitled to vote for the
Plan substantially the same information that would be required (if proxies to be
voted with respect to approval or disapproval of the Plan or amendment were then
being solicited) by the rules and regulations in effect under Section 14(a) of
the Exchange Act at the time such information is furnished; and

               (ii)  file with, or mail for filing to, the Securities and
Exchange Commission four copies of the written information referred to in
subsection (i) hereof not later than the date on which such information is first
sent or given to stockholders.

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 fair market value of such stock (determined at the time such

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 approximately twelve (12) months duration, with new Offering
Periods commencing on or about the first day of the second payroll period in
February and August of each year (or at such other time or times as may be
determined by the Board of Directors). The first Offering Period shall commence
on the beginning of the effective date of the Registration Statement on Form S-1
for the initial public offering of the Company's Common Stock (the "IPO Date")
and continue until the last day of the first payroll period in July 1999. The
Plan shall continue until terminated in accordance with Section 19 hereof. The
Board of Directors of the Company shall have the power to change the duration
and/or the frequency of Offering Periods with respect to future offerings

days prior to the scheduled beginning of the first Offering Period to be
affected. Eligible employees may not participate in more than one Offering

                                      -3-

future purchases without shareholder approval if such change is announced at
least fifteen (15) days prior to the scheduled beginning of the first Purchase
Period to be affected.

     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. The
subscription agreement shall set forth the percentage of the participant's
Compensation (which shall be not less than 1% and not more than 15%) 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)  At the time a participant files his or her subscription
agreement, the 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%) of such participant's Compensation on
each such payday. 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, during the Offering Period may increase or
decrease the rate of his or her Contributions during such Offering Period by
completing and filing with the Company a new subscription agreement; provided,
however, that no participant may effect more than one increase or decrease
during a Purchase Period. 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 to 0% at such time during an Offering
Period.  Payroll deductions shall recommence at the rate provided in such
participant's subscription Agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10.

     7.   Grant of Purchase Right.

                                      -4-
<PAGE>
 
          (a)  On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted a Purchase Right
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 Purchase Price, provided, however, that the maximum number of shares
an Employee may purchase during each Purchase Period shall be 2,500 shares of
the Company's Common Stock, and provided further that such purchase shall be
subject to the limitations set forth in Sections 3(b) and 13.  The fair market
value of a share of the Company's Common Stock shall be determined as provided
in Section 7(b).

          (b)  The Purchase Right price per share of the shares offered in a
given Offering Period shall be the Purchase Price.  The fair market value of the
Company's Common Stock on a given date shall be determined by the Board in its
discretion based on the closing 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 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 Purchase Right.  Unless a participant withdraws from the
Plan as provided in paragraph 10, his or her Purchase Right 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 Purchase Right will
be purchased at the applicable Purchase Right price with the accumulated
Contributions in his or her account. The shares purchased upon exercise of a
Purchase Right hereunder shall be deemed to be transferred to the participant on
the Purchase Date. 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. Any other monies left over in a
participant's account after a Purchase Date shall be returned to the
Participant. During his or her lifetime, a participant's Purchase Right 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, of a certificate representing the shares purchased upon exercise of
his or her Purchase Right or the deposit of such number of shares with the
broker selected by the Company for administration of Plan stock purchases, as
determined by the Company.

                                      -5-

     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 at least
five (5) business days prior to each Purchase Date by giving written notice to
the Company in the form provided in 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 Purchase Right
for the current period will be automatically terminated, and no further
Contributions for the purchase of shares will be made during the Offering
Period.

          (b)  Upon termination of the participant's Continuous Status as an
Employee (as defined in Section 2(f) hereof) 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 Purchase Right 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 Purchase Right
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 the
first 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)  The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 500,000 shares, plus an
annual increase on the first day of each of the Company's five fiscal years
beginning in 1999 and ending in 2003, equal to the lesser of (i) 375,000 shares;
(ii) two percent (2%) of the shares of Common Stock outstanding on the last day
of the immediately preceding fiscal year; or (iii) a lesser amount determined by
the Board, subject to adjustment upon changes in capitalization of the Company
as provided in Section 19.  If the total number of shares which would otherwise
be subject to Purchase Rights granted pursuant to Section 7(a) on the Offering
Date of an Offering Period exceeds the number of shares then available under the
Plan (after deduction of all shares for 

                                      -6-
<PAGE>
 
which Purchase Rights have been exercised or are then outstanding), the Company
shall make a pro rata allocation of the shares remaining available for Purchase
Right grant in as uniform a manner as shall be practicable and as it shall
determine to be equitable. In such event, the Company shall give written notice
of such reduction of the number of shares subject to the Purchase Right to each
Employee affected thereby and shall similarly reduce the rate of Contributions,
if necessary.

          (b)  The participant will have no interest or voting right in shares
covered by his or her Purchase Right until such Purchase Right 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 Purchase Right 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>
 
     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
promptly following the Purchase Date, 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 shareholders
of the Company, the number of shares of Common Stock covered by each Purchase
Right under the Plan which has not yet been exercised and the number of shares
of Common Stock which have been authorized for issuance under the Plan but have
not yet been placed under Purchase Right (collectively, the "Reserves"), as well
as the price per share of Common Stock covered by each Purchase Right under the
Plan which has not yet been exercised, 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 or
reclassification of the Common Stock, or any other increase or decrease in the
number of 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 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 of Common Stock subject to a Purchase Right.

          (b)  Corporate Transactions.  In the event of the proposed dissolution
or liquidation of the Company, the Offering Period will terminate immediately
prior to the consummation of such proposed action, unless otherwise provided by
the Board. In the event of a proposed sale of all or substantially all of the
assets of the Company, or the merger of the Company with or into another
corporation, each Purchase Right under the Plan shall be assumed or an
equivalent Purchase Right shall be substituted by such successor corporation or
a parent or subsidiary of such successor corporation, unless the Board
determines, in the exercise of its sole discretion and in lieu of such
assumption or substitution, to shorten the Offering Period then in progress by
setting a new Purchase Date (the "New Purchase Date"). If the Board shortens the
Offering Period then in progress in lieu of assumption or substitution in the
event of a merger or sale of assets, 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 Purchase Right has been changed to the New Purchase
Date and that his or her Purchase Right 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 paragraph, a
Purchase Right granted under the Plan shall be deemed to be assumed if,
following the sale of assets or merger, the Purchase Right confers the right to
purchase, for each share of Purchase Right stock subject to the Purchase 

                                      -8-
<PAGE>
 
Right immediately prior to the sale of assets or merger, the consideration
(whether stock, cash or other securities or property) received in the sale of
assets or merger by holders of Common Stock for each share of Common Stock held
on the effective date of the transaction (and if such holders were offered a
choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding shares of Common Stock); provided, however, that if
such consideration received in the sale of assets or merger was 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 and the participant, provide for the consideration to be received
upon exercise of the Purchase Right 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 and the sale of assets or
merger.

          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 Purchase Right, 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 being consolidated with or merged
into any other corporation.

     20.  Amendment or Termination.

          (a)  The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 19, no such
termination may affect Purchase Rights previously granted, provided that an
Offering Period may be terminated by the Board on a Purchase Date. Except has
provided in Section 19, no amendment make any change in any Purchase Right
theretofore 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 shareholder approval in
such a manner and to such a degree as so required.

          (b)  Without shareholder 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 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.

                                      -9-
<PAGE>
 
     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 a Purchase Right unless the exercise of such Purchase Right 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, 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 a Purchase Right, the Company may
require the person exercising such Purchase Right 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 earlier to occur of its adoption by the Board of Directors or its approval
by the shareholders of the Company.  It shall continue in effect for a term of
twenty (20) years unless sooner terminated under Section 20.

     5.   I have received a copy of the Company's most recent description of the
Plan and a copy of the complete "METAWAVE, INC. 1998 Employee Stock Purchase
Plan."  I understand that my participation in the Plan is in all respects

                                           _____________________________________

     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 Purchase Right, or (2) 15% of the fair market value of 

                                      -2-

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.

service on the Board.

          All options granted hereunder shall be nonstatutory stock options.

          (g)  "Employee" shall mean any person, including any officer or

amended.

          (i)  "Option" shall mean a stock option granted pursuant to the Plan.

without having been exercised in full, the unpurchased Shares which were subject
thereto shall, unless the Plan shall have been terminated, become available for
future grant under the Plan. If Shares which were acquired upon exercise of an
Option are subsequently repurchased by the Company, such Shares shall not in any

public offering of securities ("IPO Effective Date") shall be automatic and
nondiscretionary and shall be made strictly in accordance with the following
provisions:

               (i)  No person shall have any discretion to select which Outside
Directors shall be granted Options or to determine the number of Shares to be
covered by Options granted to Outside Directors.

an Option under this Plan shall be automatically granted an Option to purchase
Shares (the "First Option") as follows: (A) with respect to persons who are
Outside Directors on the IPO Effective Date, as determined in accordance with
Section 6 hereof, 25,000 shares on the IPO Effective Date, and (B) with respect
to any other person, 25,000 shares on the date on which such person first
becomes an Outside Director, whether through election by the stockholders of the
Company or appointment by the Board of Directors to fill a vacancy.

                                      -2-
<PAGE>
 
               (iii)  After the First Option has been granted to an Outside
Director, such Outside Director shall thereafter be automatically granted an
Option to purchase 5,000 Shares (a "Subsequent Option") on the date of each
Annual Meeting of the Company's stockholders immediately following which such
Outside Director is serving on the Board, provided that, on such date, he or she
shall have served on the Board for at least six (6) months prior to the date of
such Annual Meeting.

               (iv)  Notwithstanding the provisions of subsections (b) and (c)
hereof, in the event that a grant would cause the number of Shares subject to
outstanding Options plus the number of Shares previously purchased upon exercise
of Options to exceed the Pool, then each such automatic grant shall be for that
number of Shares determined by dividing the total number of Shares remaining
available for grant by the number of Outside Directors receiving an Option on
such date on the automatic grant date. Any further grants shall then be deferred
until such time, if any, as additional Shares become available for grant under
the Plan through action of the stockholders to increase the number of Shares
which may be issued under the Plan or through cancellation or expiration of
Options previously granted hereunder.

               (v)  Notwithstanding the provisions of subsections (ii) and (iii)
hereof, any grant of an Option made before the Company has obtained stockholder
approval of the Plan in accordance with Section 17 hereof shall be conditioned
upon obtaining such stockholder approval of the Plan in accordance with Section
17 hereof.

               (vi)  The terms of each First Option granted hereunder shall be
as follows:

                    (A)  the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof;

                    (B)  the exercise price per Share shall be 100% of the fair
market value per Share on the date of grant of the First Option, determined in
accordance with Section 8 hereof; and

                    (C)  the First Option shall become exercisable in
installments cumulatively as to 25% of the Shares subject to the First Option on
the first anniversary of the date of grant of the Option and one-forty-eighth
(1/48th) of the total number of shares subject to the Option shall vest ratably
at the end of each month thereafter upon Optionee's completion of each month of
Continuous Status as a Director.

               (vii)  The terms of each Subsequent Option granted hereunder
shall be as follows:

                    (A)  the Subsequent Option shall be exercisable only while
the Outside Director remains a Director of the Company, except as set forth in
Section 9 hereof;

                    (B)  the exercise price per Share shall be 100% of the fair
market value per Share on the date of grant of the Subsequent Option, determined
in accordance with Section 8 hereof; and

                    (C)  the Subsequent Option shall become exercisable in
installments cumulatively as to 25% of the Shares subject to the Subsequent
Option on the first anniversary of the date of grant of the Option and 
one-forty-eighth (1/48th) of the total number of shares subject to the Option
shall vest ratably at the end of each month thereafter upon Optionee's
completion of each month of Continuous Status as a Director.

          (c)  Powers of the Board.  Subject to the provisions and restrictions
of the Plan, the Board shall have the authority, in its discretion: (i) to
determine, upon review of relevant information and in accordance with Section
8(b) of the Plan, the fair market value of the Common Stock; (ii) to determine
the exercise price per share of Options to be granted, which exercise price
shall be determined in accordance with Section 8(a) of the Plan; (iii) to
interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations
relating to the Plan; (v) to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option previously
granted hereunder; and (vi) to make all other determinations deemed necessary or
advisable for the administration of the Plan.

          (d)  Effect of Board's Decision.  All decisions, determinations and
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

          (e)  Suspension or Termination of Option.  If the President or his or
her designee reasonably believes that an Optionee has committed an act of
misconduct, the President may suspend the Optionee's right to exercise any
option pending a determination by the Board of Directors (excluding the Outside
Director accused of such misconduct). If the Board of Directors (excluding the
Outside Director accused of such misconduct) determines an Optionee has
committed an act of embezzlement, fraud, dishonesty, nonpayment of an obligation
owed to the Company, breach of fiduciary duty or deliberate disregard of the
Company rules resulting in loss, damage or injury to the Company, or if an
Optionee makes an unauthorized disclosure of any Company trade secret or
confidential information, engages in any conduct constituting unfair
competition, induces any Company customer to breach a contract with the Company
or induces any principal for whom the Company acts as agent to terminate such
agency relationship, neither the Optionee nor his or her estate shall be
entitled to exercise any option whatsoever. In making such determination, the
Board of Directors (excluding the Outside Director accused of such misconduct)
shall act fairly and shall give the Optionee an opportunity to appear and
present evidence on Optionee's behalf at a hearing before the Board or a
committee of the Board.

     5.   ELIGIBILITY.  Options may be granted only to Outside Directors. After
the IPO Effective Date, all Options shall be automatically granted in accordance
with the terms set forth in Section 4(b) hereof. An Outside Director who has
been granted an Option may, if he or she is otherwise eligible, be granted an
additional Option or Options in accordance with such provisions.

          The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate his or her directorship at any time.

                                      -4-

     6.   TERM OF PLAN; EFFECTIVE DATE.  The Plan shall become effective on the
effectiveness of the registration statement under the Securities Act of 1933, as
amended, relating to the Company's initial public offering of securities.  It
shall continue in effect for a term of ten (10) years unless sooner terminated
under Section 13 of the Plan.

     7.   TERM OF OPTIONS.  The term of each Option shall be ten (10) years from
the date of grant thereof.

     8.   EXERCISE PRICE AND CONSIDERATION

          (a)  Exercise Price.  The per Share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be 100% of the fair market
value per Share on the date of grant of the Option.

          (b)  Fair Market Value.  The fair market value shall be determined by
the Board; provided, however, that where there is a public market for the Common
Stock, the fair market value per Share shall be the mean of the bid and asked
prices of the Common Stock in the over-the-counter market on the date of grant,
as reported in The Wall Street Journal (or, if not so reported, as otherwise
reported by the National Association of Securities Dealers Automated Quotation
("Nasdaq") System) or, in the event the Common Stock is traded on the Nasdaq
National Market or listed on a stock exchange, the fair market value per Share
shall be the closing price on such system or exchange on the date of grant of
the Option (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.  With respect to any Options granted hereunder concurrently with the
initial effectiveness of the Plan, the fair market value shall be the Price to
Public as set forth in the final prospectus relating to such initial public
offering.

          (c)  Form of Consideration.  The consideration to be paid for the
Shares to be issued upon exercise of an Option shall consist entirely of cash,
check, other Shares of Common Stock having a fair market value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised (which, if acquired from the Company, shall have been
held for at least six months), or any combination of such methods of payment
and/or any other consideration or method of payment as shall be permitted under
applicable corporate law.

     9.   EXERCISE OF OPTION

          (a)  Procedure for Exercise; Rights as a Stockholder.  Any Option
granted hereunder shall be exercisable at such times as are set forth by (i) the
Administrator with respect to Options granted prior to the IPO Effective Date
and (ii) by 4(b) hereof with respect to Options granted after the IPO Effective
Date; provided, however, that after the IPO Effective Date, no Options shall be
exercisable prior to stockholder approval of the Plan in accordance with Section
17 hereof.

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

                                      -5-
<PAGE>
 
               An Option shall be deemed to be 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 full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may consist of any consideration and method of payment
allowable under Section 8(c) 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 stockholder shall
exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. A share certificate for the number of Shares so acquired shall be issued
to the Optionee as soon as practicable after 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 which 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 Status as a Director.  If an Outside Director
ceases to serve as a Director, he or she may, but only within ninety (90) days
after the date he or she ceases to be a Director of the Company, exercise his or
her Option to the extent that he or she was entitled to exercise it at the date
of such termination.  Notwithstanding the foregoing, in no event may the Option
be exercised after its term set forth in Section 7 has expired.  To the extent
that such Outside Director was not entitled to exercise an Option at the date of
such termination, or does not exercise such Option (which he or she was entitled
to exercise) within the time specified herein, the Option shall terminate.

          (c)  Disability of Optionee.  Notwithstanding Section 9(b) above, in
the event a Director is unable to continue his or her service as a Director with
the Company as a result of his or her total and permanent disability (as defined
in Section 22(e)(3) of the Code), he or she may, but only within six (6) months
(or such other period of time not exceeding twelve (12) months as is determined
by the Board) from the date of such termination, exercise his or her Option to
the extent he or she was entitled to exercise it at the date of such
termination.  Notwithstanding the foregoing, in no event may the Option be
exercised after its term set forth in Section 7 has expired.  To the extent that
he or she was not entitled to exercise the Option at the date of termination, or
if he or she does not exercise such Option (which he or she was entitled to
exercise) within the time specified herein, the Option shall terminate.

          (d)  Death of Optionee.  In the event of the death of an Optionee
during the period of Continuous Status as a Director since the date of grant of
the Option, or within thirty (30) days following termination of Optionee's
Continuous Status as a Director, the Option may be exercised, at any time within
six (6) 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 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 Shares that are not subject to repurchase that had accrued at
the date of death or, if earlier, the date of termination of Optionee's
Continuous Status as a Director.  To the extent that Optionee was not entitled
to exercise the Option at the date of death or 

                                      -6-
<PAGE>
 
termination, as the case may be, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate

     10.  NONTRANSFERABILITY OF OPTIONS.  The Option 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 or pursuant to a qualified
domestic relations order (as defined by the Code or the rules thereunder).  The
designation of a beneficiary by an Optionee does not constitute a transfer.  An
Option may be exercised during the lifetime of an Optionee only by the Optionee
or a transferee permitted by this Section.

     11.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER OR CERTAIN OTHER
TRANSACTIONS.

          (a)  Changes in Capitalization.  Subject to any required action by the
stockholders 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, 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 Board,
whose determination in that respect shall be final, binding and 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 proposed
dissolution or liquidation of the Company, the Board shall notify the Optionee
at least fifteen (15) days prior to such proposed action.  To the extent it has
not been previously exercised, the Option will terminate immediately prior to
the consummation of such proposed action.

          (c)  Control Transaction.

               (i)  The Company shall provide each Optionee with notice of the
pendency of any Control Transaction (i) at least thirty (30) days prior to the
expected date of consummation of a Control Transaction that has been approved or
recommended by the Board, or (ii) promptly after the Board becomes aware of the
pendency or occurrence of a proposed or completed Control Transaction that has
not been approved or recommended by the Board.

               (ii)  Each Optionee shall be entitled to exercise the vested
portion of the Option at any time prior to consummation of a Control
Transaction. If the terms of the Option prescribe a time-based vesting schedule,
the Optionee shall, conditioned upon consummation of 

                                      -7-
<PAGE>
 
the Control Transaction and upon the Optionee continuing to serve as a Director
through the date of such consummation, be entitled to accelerated vesting credit
equal to either twelve months or twenty-four months of additional vesting beyond
that otherwise scheduled, based on whether he or she has been in Continuous
Status as a Director less than two years, or two years or more, respectively, as
of the date of such consummation; provided, however, that this sentence shall
not apply with respect to any Option as to which the Administrator determines,
in its sole discretion, that the Board or the acquiring person or the surviving
corporation, as the case may be, has made equitable and appropriate provision
for the assumption of or the substitution of a new option for the Option on
terms which are, as nearly as practicable, the financial equivalent of the
Option (taking into account the consideration for which the Common Stock is to
be exchanged in the Control Transaction).

               (iii)  Any exercise may be made contingent upon consummation of a
Control Transaction if so elected by the Optionee in his or her notice of
exercise, and must be made contingent upon such consummation with respect to any
portion of an Option entitled to accelerated vesting under the second sentence
of Section 11(c)(ii) above.

               (iv)  Upon consummation of a Control Transaction that has been
approved or recommended by the Board, all unexercised Options shall expire,
except to the extent that the Administrator determines otherwise pursuant to the
second sentence of Section 11(c)(ii) above.

          (d)  Certain Distributions.  In the event of any distribution to the
Company's stockholders 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.

     12.  TIME OF GRANTING OPTIONS.  With respect to Options granted after the
IPO Effective Date, the date of grant of an Option shall, for all purposes, be
the date determined in accordance with Section 4(b) hereof.  Notice of the
determination shall be given to each Outside Director to whom an Option is so
granted within a reasonable time after the date of such grant.

     13.  AMENDMENT AND TERMINATION OF THE PLAN

          (a)  Amendment and Termination.  The Board may amend or terminate the
Plan from time to time in such respects as the Board may deem advisable;
provided that, to the extent necessary and desirable to comply with Rule 16b-3
under the Exchange Act (or any other applicable law or regulation), the Company
shall obtain approval of the stockholders of the Company to Plan amendments to
the extent and in the manner required by such law or regulation.
Notwithstanding the foregoing, the provisions set forth in Section 4 of this
Plan (and any other Sections of this Plan that affect the formula award terms
required to be specified in this Plan by Rule 16b-3) shall not be amended more
than once every six months, other than to comport with changes in the Code, the
Employee Retirement Income Security Act of 1974, as amended, or the rules
thereunder.

                                      -8-
<PAGE>
 
          (b)  Effect of Amendment or Termination.  Any such amendment or
termination of the Plan that would impair the rights of any Optionee shall not
affect Options already granted to such Optionee and such Options shall remain in
full force and effect as if this Plan had not been amended or terminated, unless
mutually agreed otherwise between the Optionee and the Board, which agreement
must be in writing and signed by the Optionee and the Company.

     14.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, 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
relevant provisions of law.

     15.  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.  Inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

     16.  OPTION AGREEMENT.  Options shall be evidenced by written option
agreements in such form as the Board shall approve.

     17.  STOCKHOLDER APPROVAL.  Continuance of the Plan shall be subject to
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the granting of an Option hereunder.
If such stockholder approval is obtained at a duly held stockholders' meeting,
it may be obtained by the affirmative vote of the holders of a majority of the
outstanding shares of the Company present or represented and entitled to vote
thereon.

June 30, 2000, or (ii) six (6) months after the effective date of the first
registration statement for a public offering of securities of the Company (other
than a registration statement relating either to the sale of securities to
employees of the Company pursuant to a stock option, stock purchase or similar
plan or a SEC Rule 145 transaction), a written request, from (i) the Holders of
a majority of the Registrable Securities then outstanding in the case of the
first such written request and (ii) the Holders of at least forty percent (40%)
of the Registrable Securities then outstanding in the case of the second such
request, that the Company file a registration statement under the Act covering
the registration of Registrable Securities then outstanding having an aggregate
offering price, net of underwriting discounts and commissions, of at least
$7,500,000, then the Company shall:

          (A) within ten (10) days of the receipt thereof, give written notice
of such request to all Holders; and

          (B) effect as soon as practicable, and in any event within sixty (60)
days of the receipt of such request, the registration under the Act of all
Registrable Securities that the Holders request to be registered, subject to the
limitations of subsection 1.2(b), within twenty (20) days of the mailing of such
notice by the Company in accordance with Section 3.5.

          (1) If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to subsection 1.2(a) and the Company
shall include such information in the written notice referred to in subsection
1.2(a).  The underwriter will be selected by the majority in interest of the
Initiating Holders.  In such event, the right of any Holder to include his
Registrable Securities in such registration shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein.  All Holders proposing to distribute their securities through
such underwriting shall (together with the Company as provided in 

                                      -3-

<PAGE>
 
subsection 1.4(e)) enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for such underwriting. Notwithstanding
any other provision of this Section 1.2, if the underwriter advises the
Initiating Holders in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the Initiating Holders shall so advise
all Holders of Registrable Securities that would otherwise be underwritten
pursuant hereto, and the number of shares of Registrable Securities that may be
included in the underwriting shall be allocated among all Holders (electing to
include shares in the offering) thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of
the Company owned by each Holder; provided, however, that the number of shares
of Registrable Securities to be included in such underwriting shall not be
reduced unless all other securities are first entirely excluded from the
underwriting.

          (2) Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting a registration statement pursuant to this Section 1.2, a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its stockholders for such registration statement
to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than ninety (90) days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve (12) month
period.

          (3) The Company is obligated to effect only two (2) such registrations
pursuant to this Section 1.2.

          1.3  Company Registration

          (a) If (but without any obligation to do so) the Company proposes to
register (including for this purpose a registration effected by the Company for
stockholders other than the Holders) any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock plan or a registration on any form that does not
include substantially the same information as would be required to be included
in a registration statement covering the sale of the Registrable Securities),
the Company shall, at such time, promptly give each Holder written notice of
such registration.  Upon the written request of each Holder given within twenty
(20) days after mailing of such notice by the Company in accordance with Section
3.5, the Company shall, subject to the provisions of Section 1.8, include in the
registration statement all of the Registrable Securities that each such Holder
has requested to be registered.

          (b) Each Founder shall be deemed a Holder for purposes of Section
1.3(a) and shall be entitled to include Common Stock held by such Founder in any
registration described in Section 1.3(a) so long as such Founder (A) continues
to serve as an officer or director of the Company on the date the registration
statement is filed by the Company 

                                      -4-
<PAGE>
 
and (B) agrees to be bound by all other provisions of this Agreement and to
participate in any such registration on the same basis as each other Holder in
accordance with all applicable provisions of this Agreement.

          1.4  Obligations of the Company.  Whenever required under this Section
1 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

          (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for a period of up to one hundred twenty (120)
days or until the Holders have completed the distribution described in the
registration statement relating thereto, whichever first occurs.

          (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

          (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or "Blue Sky"
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

          (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

                                      -5-
<PAGE>
 
          (g) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange or nationally recognized
quotation system on which similar securities issued by the Company are then
listed.

          1.5  Furnish Information

          (a) It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Section 1 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of such securities as shall be
required to effect the registration of such Holder's Registrable Securities.

          (b) The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 or Section 1.12 if, due to the
operation of subsection 1.5(a), the number of shares or the anticipated
aggregate offering price of the Registrable Securities to be included in the
registration does not equal or exceed the number of shares or the anticipated
aggregate offering price required to originally trigger the Company's obligation
to initiate such registration as specified in subsection 1.2(a) or subsection
1.12(b)(ii), whichever is applicable.

          1.6  Expenses of Demand Registration.  All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company and the
reasonable fees and disbursements of one counsel (not to exceed $10,000) for the
selling Holders shall be borne by the Company; provided, however, that the
Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant to Section 1.2 if the registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all participating Holders
shall bear such expenses), unless the Holders of a majority of the Registrable
Securities agree to forfeit their right to one demand registration pursuant to
Section 1.2; provided further, however, that if at the time of such withdrawal,
the Holders have learned of a material adverse change in the condition,
business, or prospects of the Company from that known to the Holders at the time
of their request and have withdrawn the request with reasonable promptness
following disclosure by the Company of such material adverse change, then the
Holders shall not be required to pay any of such expenses and shall retain their
rights pursuant to Section 1.2.

          1.7  Expenses of Company Registration.  The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing, and
qualification fees, printers' and accounting fees relating or apportionable
thereto and the fees and disbursements of counsel for this purpose; the Company
will pay the reasonable fees 

                                      -6-
<PAGE>
 
and disbursements of one counsel (not to exceed $10,000), for the selling
Holders selected by them but excluding underwriting discounts and commissions
relating to Registrable Securities.

          1.8  Underwriting Requirements.  In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it, and then
only in such quantity as the underwriters determine in their sole discretion
will not adversely affect their ability to market the offering.  If the total
amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, that the underwriters determine in
their sole discretion will not adversely affect their ability to market the
offering (the securities so included to be apportioned pro rata among the
selling stockholders according to the total amount of securities owned by each
selling stockholder or in such other proportions as shall mutually be agreed to
by such selling stockholders) but in no event shall (a) the amount of securities
of the selling Holders included in the offering be reduced below thirty percent
(30%) of the total amount of securities included in such offering, unless such
offering is the initial public offering of the Company's securities in which
case the selling stockholders may be reduced to a lesser percentage if the
underwriters make the determination described above and no other stockholder's
securities are included or (b) notwithstanding clause (a) above, any shares
being sold by a stockholder exercising a demand registration right similar to
that granted in Section 1.2 be excluded from such offering.  For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder
that is a holder of Registrable Securities and which is a partnership or
corporation, the partners, retired partners and stockholders of such holder, or
the estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "selling stockholder", and any pro-rata reduction with respect to such
"selling stockholder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "selling stockholder", as defined in this sentence.

          1.9  Delay of Registration.  No Holder shall have any right to obtain
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

          1.10  Indemnification.  In the event any Registrable Securities are
included in a registration statement under this Section 1:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may 

                                      -7-
<PAGE>
 
become subject under the Act, or the 1934 Act or other federal or state
securities law, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the Act, or the
1934 Act or any state securities law; and the Company will pay to each such
Holder, underwriter or controlling person, as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 1.10(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable in any such case for any such loss, claim, damage, liability, or action
to the extent that it arises out of or is based upon a Violation that occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, underwriter or
controlling person.

          (b) To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
has signed the registration statement, each person, if any, who controls the
Company within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, against any losses, claims, damages, or liabilities
(joint or several) to which any of the foregoing persons may become subject,
under the Act, the 1934 Act or other federal or state securities law, insofar as
such losses, claims, damages, or liabilities (or actions in respect thereto)
arise out of or are based upon any Violation, in each case to the extent (and
only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished by such Holder expressly for use
in connection with such registration; and each such Holder will pay, as
incurred, any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this subsection 1.10(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
1.10(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder, which consent shall not be unreasonably withheld; provided, that,
in no event shall any indemnity under this subsection 1.10(b) exceed the net
proceeds from the offering received by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section
1.10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.10, deliver to the
indemnifying party a written notice 

                                      -8-
<PAGE>
 
of the commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume the defense
thereof with counsel mutually satisfactory to the parties; provided, however,
that an indemnified party (together with all other indemnified parties that may
be represented without conflict by one counsel) shall have the right to retain
one separate counsel, with the fees and expenses to be paid by the indemnifying
party, if representation of such indemnified party by the counsel retained by
the indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, if materially prejudicial to its ability to defend such action,
shall relieve such indemnifying party of any liability to the indemnified party
under this Section 1.10, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 1.10.

          (d) If the indemnification provided for in this Section 1.10 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations.  The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

          (e) The obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

          1.11  Reports Under Securities Exchange Act of 1934.  With a view to
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration or
pursuant to a registration on Form S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after the effective date of
the first registration statement filed by the Company for the offering of its
securities to the general public;

                                      -9-
<PAGE>
 
          (b) take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

          (c) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (d) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company), the Act and the 1934 Act (at any time after it
has become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC that permits the
selling of any such securities without registration or pursuant to such form.

          1.12  Form S-3 Registration.  In case the Company shall receive from
any Holder or Holders a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will:

          (a) promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders; and

          (b) as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 1.12:  (i)
if Form S-3 is not available for such offering by the Holders; (ii) if the
Holders, together with the holders of any other securities of the Company
entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at an aggregate price to the
public (net of any underwriters' discounts or commissions) of less than
$1,000,000; (iii) if the Company shall furnish to the Holders a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors of the Company, it would be seriously detrimental to
the Company and its stockholders for such Form S-3 Registration to be effected
at such time, in which event the Company shall have the right to defer the
filing of the Form S-3 registration statement for a period of not more than 90
days after 

                                     -10-
<PAGE>
 
receipt of the request of the Holder or Holders under this Section 1.12;
provided, however, that the Company shall not utilize this right more than once
in any twelve (12) month period; (iv) if the Company has, within the twelve (12)
month period preceding the date of such request, already effected (A) one (1)
registration on Form S-3 for the requesting Holder or Holders or (B) two (2)
registrations on Form S-3 pursuant to this Section 1.12; (v) if the Company has
already effected four (4) registrations on Form S-3 pursuant to this Section
1.12; or (vi) in any particular jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance.

          (c) Subject to the foregoing, the Company shall file a registration
statement covering the Registrable Securities and other securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Holders.  All expenses incurred in connection with a registration
requested pursuant to Section 1.12, including (without limitation) all
registration, filing, qualification, printer's and accounting fees and the
reasonable fees and disbursements of counsel (not to exceed $10,000) for the
selling Holder or Holders and counsel for the Company, but excluding any
underwriters' discounts or commissions associated with Registrable Securities,
shall be borne by the Company.  Registrations effected pursuant to this Section
1.12 shall not be counted as demands for registration or registrations effected
pursuant to Sections 1.2 or 1.3, respectively.

          1.13  Assignment of Registration Rights.  The rights to cause the
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who acquires all of the Registrable Securities
previously held by such Holder, or who, after such assignment or transfer, holds
at least 100,000 shares of Registrable Securities (subject to appropriate
adjustment for stock splits, stock dividends, combinations and other
recapitalizations), provided: the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.  For the purposes of determining the number of shares
of Registrable Securities held by a transferee or assignee, the holdings of
transferees and assignees of a partnership who are partners or retired partners
of such partnership (including spouses and ancestors, lineal descendants and
siblings of such partners or spouses who acquire Registrable Securities by gift,
will or intestate succession) shall be aggregated together and with the
partnership; provided that all assignees and transferees who would not qualify
individually for assignment of registration rights shall have a single attorney-
in-fact for the purpose of exercising any rights, receiving notices or taking
any action under this Section 1.

          1.14  Limitations on Subsequent Registration Rights.  From and after
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the Registrable Securities then
outstanding, enter into any agreement with any holder or 

                                     -11-
<PAGE>
 
prospective holder of any securities of the Company that would allow such holder
or prospective holder (a) to include such securities in any registration filed
under Section 1.2 hereof, unless under the terms of such agreement, such holder
or prospective holder may include such securities in any such registration only
to the extent that the inclusion of his securities will not reduce the amount of
the Registrable Securities of the Holders that is included or (b) to make a
demand registration which could result in such registration statement being
declared effective prior to the earlier of either of the dates set forth in
subsection 1.2(a) or within one hundred twenty (120) days of the effective date
of any registration effected pursuant to Section 1.2.

          1.15  "Market Stand-Off" Agreement.  Each Investor hereby agrees that,
during the period of duration (not to exceed one hundred eighty (180) days)
specified by the Company and an underwriter of Common Stock or other securities
of the Company, following the effective date of a registration statement filed
under the Act for the initial public offering of the Company's Common Stock, it
shall not, to the extent requested by the Company and such underwriter, directly
or indirectly, sell, offer to sell, contract to sell (including, without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of (other than to donees who agree to be similarly bound) any
securities of the Company held by it at any time during such period except
Common Stock included in such registration; provided, however, that the
restrictions imposed by this subsection 1.15 shall not apply to Common Stock
purchased by an Investor in the initial public offering of the Company's Common
Stock or acquired by an Investor by purchases in the public market following
such initial public offering; and provided further, that all officers and
directors of the Company and all other persons with registration rights (whether
or not pursuant to this Agreement) enter into similar agreements.  In order to
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the securities of the Company (except Common Stock
included in such registration) held at any time during such period by each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

          1.16  Termination of Registration Rights

          No Holder shall be entitled to exercise any right provided for in this
Section 1 after the earlier of (a) three (3) years following the consummation of
the sale of securities pursuant to a registration statement filed by the Company
under the Act in connection with the initial firm commitment underwritten
offering of its securities to the general public, the public offering price of
which was not less than $9.25 per share (adjusted to reflect subsequent stock
dividends, stock splits or recapitalizations), and $15,000,000 in the aggregate,
or (b) as to any Holder, such time at which all Registrable Securities held by
such Holder can be sold in any three month period without registration in
compliance with Rule 144 of the Act.

          2.  Covenants

               2.1  Delivery of Financial Statements.  The Company shall deliver
to each Investor:

          (a) as soon as practicable, but in any event within ninety (90) days
after the end of each fiscal 

                                     -12-

be in reasonable detail, prepared in accordance with generally accepted
accounting principles ("GAAP"), and audited and certified by independent public
accountants of nationally recognized standing selected by the Company;

          (b) so long as such Investor holds an aggregate of at least 400,000
shares of Series A, Series B, Series C and/or Series D Preferred Stock (or
Common Stock issued upon conversion thereof and as adjusted for subsequent stock
splits, recombinations or reclassifications) as soon as practicable, but in any
event within thirty (30) days after the end of each of the first three (3)
quarters of each fiscal year of the Company, an unaudited income statement,
statement of cash flows for such fiscal quarter and an unaudited balance sheet
as of the end of such fiscal quarter;

          (c) so long as such Investor holds an aggregate of at least 400,000
shares of Series A, Series B, Series C and/or Series D Preferred Stock (or
Common Stock issued upon conversion thereof and as adjusted for subsequent stock
splits, recombinations or reclassifications) within thirty (30) days of the end
of each month, an unaudited income statement, statement of cash flows and
balance sheet for and as of the end of such month, in reasonable detail;

          (d) so long as such Investor holds an aggregate of at least 400,000

Common Stock issued upon conversion thereof and as adjusted for subsequent stock
splits, recombinations or reclassifications) as soon as practicable, but in any
event thirty (30) days prior to the end of each fiscal year, a budget and
business plan for the next fiscal year, prepared on a monthly basis, including
balance sheets and income statements for such months and, as soon as prepared,
any other budgets or revised budgets prepared by the Company;

          (e) with respect to the financial statements called for in subsections
(b) and (c) of this Section 2.1, an instrument executed by the Chief Financial
Officer or Chief Executive Officer of the Company and certifying that such
financials were prepared in accordance with GAAP consistently applied with prior
practice for earlier periods (with the exception of footnotes that may be
required by GAAP) and fairly present the financial condition of the Company and
its results of operation for the period specified, subject to year-end audit
adjustment;

          (f) such other information relating to the financial condition,
business, prospects or corporate affairs of the Company as the Investor or any
assignee of the Investor may from time to time request, provided, however, that
the Company shall not be obligated under this subsection (f) or any other
subsection of Section 2.1 to provide information which it deems in good faith to
be a trade secret or similar confidential information.

                                     -13-

          2.2  Inspection.  The Company shall permit each Investor, at such
Investor's expense, to visit and inspect the Company's properties, to examine
its books of account and records and to discuss the Company's affairs, finances
and accounts with its officers, all at such reasonable times as may be requested
by the Investor; provided, however, that the Company shall not be obligated
pursuant to this Section 2.2 to provide access to any information that it
reasonably considers to be a trade secret or similar confidential information.

          2.3  Termination of Information and Inspection Covenants.  The
covenants set forth in Section 2.1 and Section 2.2 shall terminate as to
Investors and be of no further force or effect (a) when the sale of securities
pursuant to a registration statement filed by the Company under the Act in
connection with the firm commitment underwritten offering of its securities to
the general public is consummated, the public offering price of which was not
less than $9.25 per share (adjusted to reflect subsequent stock dividends, stock
splits or recapitalizations), and $15,000,000 in the aggregate or (b) when the
Company first becomes subject to the periodic reporting requirements of Sections
12(g) or 15(d) of the 1934 Act, whichever event shall first occur.

          2.4  Right of First Offer.  Subject to the terms and conditions
specified in this Section 2.4, the Company hereby grants to each Investor a
right of first offer to purchase its pro rata share (in whole or in part) with
respect to future sales by the Company of its Shares (as hereinafter defined).
An Investor shall be entitled to assign or apportion the right of first offer
hereby granted it among itself and its partners and affiliates (including in the
case of a venture capital fund among other venture capital funds affiliated with
such fund) in such proportions as it deems appropriate.  For purposes of this
Section 2.4, an Investor's pro rata share of Shares shall mean that number of
Shares that equals the proportion that the number of shares of Common Stock
issued and held by each Investor (assuming full conversion, exercise and/or
exchange of all convertible, exercisable and exchangeable securities) bears to
the total number of shares of Common Stock issued and outstanding immediately
prior to the issuance of Shares (assuming full conversion, exercise and/or
exchange of all convertible, exercisable and exchangeable securities).
Notwithstanding anything herein to the contrary, if the aggregate number of
Shares which the Investors elect to purchase pursuant to this Section 2.4
exceeds sixty-six and two-thirds percent (66 2/3%) of the Shares to be offered
by the Company, the number of Shares to be purchased by each Investor shall be
reduced proportionately so that the aggregate number of Shares to be purchased
by the Investors is no more than sixty-six and two-thirds percent (66 2/3%) of
the Shares to be issued.

          Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital
stock ("Shares"), the Company shall first make an offering of such Shares to
each Investor in accordance with the following provisions:

          (a) The Company shall deliver a notice by certified mail ("Notice") to
the Investors stating (i) its bona fide intention to offer such Shares, (ii) the
number of such Shares to be offered, and (iii) the price and terms, if any, upon
which it proposes to offer such Shares.

                                     -14-
<PAGE>
 
          (b) By written notification received by the Company within twenty (20)
calendar days after receipt of the Notice, each Investor may elect to purchase
or obtain, at the price and on the terms specified in the Notice, up to its pro
rata share of such Shares.

          (c) If all Shares that Investors are entitled to obtain pursuant to
subsection 2.4(b) are not elected to be obtained as provided in subsection
2.4(b) hereof, the Company may, during the 30-day period following the
expiration of the period provided in subsection 2.4(b) hereof, offer the
remaining unsubscribed portion of such Shares to any person or persons at a
price not less than, and upon terms no more favorable to the offeree than those
specified in the Notice.  If the Company does not enter into an agreement for
the sale of the Shares within such period, or if such agreement is not
consummated within 30 days of the execution thereof, the right provided
hereunder shall be deemed to be revived and such Shares shall not be offered
unless first reoffered to the Investors in accordance herewith.

          (d) The right of first offer in this Section 2.4 shall not be
applicable (i) to the issuance or sale of no more than 3,950,000 shares of
Common Stock (or options therefor, including the number of options outstanding
as of the date of this Agreement) to employees, consultants or directors for the
primary purpose of soliciting or retaining their services, (ii) to or after
consummation of a bona fide, firmly underwritten public offering of shares of
Common Stock, registered under the Act pursuant to a registration statement on
Form S-1, at an offering price of at least $9.25 per share (appropriately
adjusted for any stock split, dividend, combination or other recapitalization)
and $15,000,000 in the aggregate, (iii) the issuance of securities pursuant to
the conversion or exercise of convertible or exercisable securities, (iv) the
issuance of securities in connection with a bona fide business acquisition of or
by the Company, whether by merger, consolidation, sale of assets, sale or
exchange of stock or otherwise, (v) the issuance of securities in connection
with a transaction the primary purpose of which is to acquire technology, (vi)
the issuance of securities to vendors, suppliers, equipment lessors or bank
lenders where such issuance is not principally for the purpose of raising
additional equity capital; or (vii) the issuance of securities to corporate
partners or in connection with other strategic alliances approved by the Board
of Directors of the Company.

          2.5  Board of Directors

          (a) With respect to those three (3) directors that the Company's Third
Amended and Restated Certificate of Incorporation provides are to be elected by
holders of Series A, Series B, Series C and Series D Preferred Stock, the
Investors hereby agree to vote all of their shares of Series A, Series B, Series
C and Series D Preferred Stock in favor of the election of one designee of each
of Venrock Associates ("Venrock"), Sevin Rosen Fund IV, L.P. ("Sevin Rosen"),
and Oak Investment Partners VI, L.P. ("Oak").  Notwithstanding the foregoing if
pursuant to Article IV, Section (B), Paragraph 5(b) of the Company's Third
Amended and Restated Certificate of Incorporation (which Paragraph is entitled
"Voting for the Election of Directors"), as such provision may be amended from
time to time, the number of directors to be elected by the holders of Series A,
Series B, Series C and Series D Preferred Stock shall be decreased from three
(3) directors to either two (2) directors or one (1) director, then among

                                     -15-
<PAGE>
 
Venrock, Sevin Rosen and Oak, those two (2) stockholders (in the case where the
Series A, Series B, Series C and Series D Preferred Stock elects two (2)
directors) or the one (1) stockholder (in the case where the Series A, Series B,
Series C and Series D Preferred Stock elects one (1) director) holding the most
shares of Series A, Series B, Series C and Series D Preferred Stock shall be
entitled to designate the director(s) pursuant to this subsection (a).

          (b) So long as (i) Integral Capital Partners III, L.P. ("Integral") or
(ii) Bowman Capital or its related entities ("Bowman") holds an aggregate of at
least 243,507 shares of Series C Preferred Stock and/or Series D Preferred Stock
(or Common Stock issued upon conversion thereof and as adjusted for subsequent
stock splits, recombinations or reclassifications), the Company shall invite one
(1) designated representative of each of Integral and Bowman to attend all
meetings of its Board of Directors in a nonvoting advisory capacity, and so long
as any Investor holds an aggregate of at least 324,675 shares of Series C
Preferred Stock and/or Series D Preferred Stock (or Common Stock issued upon
conversion thereof and as adjusted for subsequent stock splits, recombinations
or reclassifications), the Company shall invite one (1) designated
representative of such Investor to attend all meetings of its Board of Directors
in a nonvoting observer capacity.  The Company shall give such designated
representatives copies of all notices, minutes, consents, and other materials
that it provides to its directors at the same time as such materials are
provided to the directors; provided, however, that such representatives shall
agree to hold in confidence and trust and to act in a fiduciary manner with
respect to all information so provided; and, provided further, that the Company
reserves the right to withhold any information and to exclude such
representatives from any meeting or portion thereof if the Company believes,
upon advise of counsel, that such exclusion is reasonably necessary to preserve
the attorney-client privilege, to protect highly confidential information, or
for other similar reasons.  The covenants and rights set forth in this Section
2.6 shall terminate and be of no further force or effect upon the closing of the
Company's initial firm commitment underwritten offering of its securities to the
general public, the public offering price of which was not less than $9.25 per
share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalizations), and $15,000,000 in the aggregate.

          3.  Miscellaneous

          3.1  Successors and Assigns.  Except as otherwise provided herein, 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 (including
transferees of any shares of Registrable Securities).  Nothing in this
Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or 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.

          3.2  Governing Law.  This Agreement shall be governed by and construed
under the laws of the State of Delaware as applied to agreements among Delaware
residents entered into and to be performed entirely within Delaware.

                                     -16-
<PAGE>
 
          3.3  Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

          3.4  Titles and Subtitles.  The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

          3.5  Notices.  Unless otherwise provided, any notice required or
permitted under this Agreement shall be given in writing and shall be deemed
effectively given upon personal delivery to the party to be notified or upon
delivery by facsimile or overnight courier or upon deposit with the United
States Post Office, by registered or certified mail, postage prepaid and
addressed to the party to be notified at the address indicated for such party on
the signature page hereof, or at such other address as such party may designate
by ten (10) days' advance written notice to the other parties.

          3.6  Expenses.  If any action at law or in equity is necessary to
enforce or interpret the terms of this Agreement, the prevailing party shall be
entitled to reasonable attorneys' fees, costs and necessary disbursements in
addition to any other relief to which such party may be entitled.

          3.7  Amendments and Waivers.  Any term of this Agreement may be
amended and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders of
at least sixty-five percent (65%) of the Registrable Securities then
outstanding; provided, however, that in the event such amendment or waiver (a)
adversely affects the rights and/or obligations of an individual Holder in a
different manner than the other Holders, such amendment or waiver shall also
require the written consent of such individual Holder or (b) adversely affects
the rights and/or obligations of the Founders under Section 1 of this Agreement
in a different manner than the other Holders, such amendment or waiver shall
also require the written consent of the Holders of at least a majority of the
Common Stock (assuming the conversion of all outstanding shares of Preferred
Stock) then held by the Founders; or (c) affects the rights and/or obligations
of Integral and/or Bowman under Section 2.5(b) of this Agreement, such amendment
or waiver shall also require the written consent of Integral and/or Bowman, as
the case may be.

          3.8  Severability.  If one or more provisions of this Agreement are
held to be unenforceable under applicable law, such provision shall be excluded
from this Agreement, and the balance of the Agreement shall be interpreted as if
such provision were so excluded, and shall be enforceable in accordance with its
terms.

          3.9  Aggregation of Stock.  All shares of Registrable Securities of
the Company held or acquired by affiliated stockholders shall be aggregated
together for the purpose of determining the availability of any rights under
this Agreement.  For purposes of the foregoing, the shares held by any
stockholder that (a) is a partnership or corporation shall be 

                                     -17-
<PAGE>
 
deemed to include shares held by the partners, retired partners and stockholders
of such holder or members of the "immediate family" (as defined below) of any
such partners, retired partners and stockholders, and any custodian or trustee
for the benefit of any of the foregoing persons and (b) is an individual shall
be deemed to include shares held by any members of the stockholder's immediate
family ("immediate family" shall include any spouse, father, mother, brother,
sister, lineal descendant of spouse or lineal descendant) or to any custodian or
trustee for the benefit of any of the foregoing persons.

          3.10  Amendment and Restatement.  The Company, the Founders and the
Investors consent to the execution of this Agreement, and to any and all other
documents and agreements contemplated hereby and waive any and all rights they
may have to object hereto or thereto and agree that this Agreement supersedes in
all respects all prior agreements relating to the rights set forth herein,
including the Second Restated Investors' Rights Agreement.

     B.   Payment of Operating Cost Share Rent and Tax Share Rent.
          ------------------------------------------------------- 

          (1)  Payment of Estimated Operating Cost Share Rent and Tax Share Rent
               -----------------------------------------------------------------
Landlord shall estimate the Operating Costs and Taxes of the Project by April 1
of each fiscal year, or as soon as reasonably possible thereafter.  Landlord may
revise these estimates whenever it obtains more accurate information, such as
the final real estate tax assessment or tax rate for the Project.

          Within ten (10) days after receiving the original or revised estimate
from Landlord, Tenant shall pay Landlord one-twelfth (1/12th) of Tenant's
Proportionate Share of this estimate, multiplied by the number of months that
have elapsed in the applicable fiscal year to the date of such payment including
the current month, minus payments previously made by Tenant for the months
elapsed.  On the first day of each month thereafter, Tenant shall pay Landlord
one-twelfth (1/12th) of Tenant's Proportionate Share of this estimate, until a
new estimate becomes applicable.

          (2)  Correction of Operating Cost Share Rent.  Landlord shall deliver
               ---------------------------------------
to Tenant a report for the previous fiscal year (the "Operating Cost Report") by
                                                      ---------------------
April 1 of each year, or as soon as reasonably possible thereafter, setting
forth (a) the actual Operating Costs incurred, (b) the amount of Operating Cost
Share Rent due from Tenant, and (c) the amount of Operating Cost Share Rent paid
by Tenant.  Within twenty (20) days after such delivery, Tenant shall pay to
Landlord the amount due minus the amount paid.  If the amount paid exceeds the
amount due, Landlord shall apply the excess to Tenant's payments of Operating
Cost Share Rent next coming due.

          (3)  Correction of Tax Share Rent.  Landlord shall deliver to Tenant a
               ----------------------------
report for the previous fiscal year (the "Tax Report") by April 1 of each year,
                                          ----------
or as soon as reasonably possible thereafter, setting forth (a) the actual
Taxes, (b) the amount of Tax Share Rent due from Tenant, and (c) the amount of
Tax Share Rent paid by Tenant.  Within twenty (20) days after such delivery,
Tenant shall pay to Landlord the amount due from Tenant minus the amount paid by
Tenant.  If the amount paid exceeds the amount due, Landlord shall apply any
excess as a credit against Tenant's payments of Tax Share Rent next coming due.

     C.   Definitions.
          ----------- 

          (1)  Included Operating Costs. "Operating Costs" means any expenses,
               ------------------------   ---------------
costs and disbursements of any kind other than Taxes, paid or incurred by
Landlord in connection with the management, maintenance, operation, insurance,
repair and other related activities in connection with any part of the Project
and of the personal property, fixtures, machinery, equipment, systems and
apparatus used in connection therewith, including the cost of providing those
repair, maintenance and services required to be furnished by Landlord to the
Premises and Building under this Lease, a management fee 

                                       4

in an amount equal to three percent (3%) of the annual Base Rent and accounting
and administration costs incurred by Landlord with respect to the Project.
Operating Costs shall also include the costs of any capital improvements (other
than Landlord's Work, Initial Improvements, and Additional Improvements) which
reduce Operating Costs or improve safety, and those made to keep the Project in
compliance with governmental requirements applicable from time to time
(collectively, "Included Capital Items"); provided, that the costs of any
Included Capital Item shall be amortized by Landlord, together with an amount
equal to interest at ten percent (10%) per annum, over the estimated useful life
of such item and such amortized costs are only included in Operating Costs for
that portion of the useful life of the Included Capital Item which falls within
the Term.

          If the Project is not fully occupied during any portion of any fiscal
year, Landlord may adjust (an "Equitable Adjustment") Operating Costs to equal
                               --------------------
what would have been incurred by Landlord had the Project been fully occupied.
This Equitable Adjustment shall apply only to Operating Costs which are variable
and therefore increase as occupancy of the Project increases.  Landlord may
incorporate the Equitable Adjustment in its estimates of Operating Costs.

          If Landlord does not furnish any particular service whose cost would
have constituted an Operating Cost to a tenant other than Tenant who has
undertaken to perform such service itself, Operating Costs shall be increased by
the amount which Landlord would have incurred if it had furnished the service to
such tenant.

          (2)  Excluded Operating Costs.  Operating Costs shall not include:
               ------------------------

               Capital Items;

                         (c)  interest and principal payments on mortgages or

               thereof;

                         (f)  any cost or expenditure for which Landlord is

               Operating Cost Share Rent;

               Items);

                         (i)  franchise or income taxes imposed upon Landlord;

                         (j)  costs of correcting defects in construction of the
               Building, including Building Shell, Initial Improvements and
               Additional Improvements  (as opposed to the cost of normal
               repair, maintenance and replacement expected with the
               construction materials and equipment installed in the Building in
               light of their specifications);

                         (k)  legal and auditing fees which are for the benefit
               of Landlord such as collecting delinquent rents, preparing tax

               required pursuant to Section 2B above;

                         (l)  the wages of any employee for services not related
               directly to the day to day management, maintenance, operation and

by Landlord relating to the Project in excess of industry standard deductibles

of any kind, general or special, ordinary or extraordinary, levied against the
Project, which Landlord shall pay or become obligated to pay in connection with

          For any year, the amount to be included in Taxes (a) from taxes or
assessments payable in installments, shall be the amount of the installments
(with any interest) due and payable during such year, and (b) from all other
Taxes, shall at Landlord's election be the amount accrued, assessed, or

          Taxes shall not include any net income (except Rent Tax), capital,

to the extent that such tax shall be imposed in lieu of any portion of Taxes.

          (4)  Lease Year.  "Lease Year" means each consecutive twelve-month
               ----------    ----------
period beginning with the Commencement Date, except that if the Commencement

be the period from the Commencement Date through the final day of the twelve
months after the first day of the following month, and each subsequent Lease
Year shall be the twelve months following the prior Lease Year.

          (5)  Fiscal Year.  "Fiscal Year" means the calendar year, except that
               -----------    -----------
the first fiscal year and the last fiscal year of the Term may be a partial
calendar year.

     D.   Computation of Base Rent and Rent Adjustments.
          --------------------------------------------- 

          (1)  Prorations.  If this Lease begins on a day other than the first
               ----------
day of a month, the Base Rent, Operating Cost Share Rent and Tax Share Rent
shall be prorated for such partial month based on the actual number of days in

          (2)  Default Interest.  Any sum due from Tenant to Landlord not paid
               ----------------
when due shall bear interest from the date due until paid at ten and one half
percent (10.5%).

          (3)  Rent Adjustments.  The square footage of the Premises and the
               ----------------
Building set forth in the Schedule are conclusively deemed to be the actual
square footage thereof, without regard to any subsequent remeasurement of the
Premises or the Building.  If any Operating Cost paid in one fiscal year relates
to more than one fiscal year, Landlord may proportionately allocate such
Operating Cost among the related fiscal years.

          (4)  Books and Records.  Landlord shall maintain books and records
               -----------------
reflecting the Operating Costs and Taxes in accordance with sound accounting and
management practices.  Tenant and its certified public accountant shall have the
right to inspect Landlord's records at Landlord's office upon at least seventy-
two (72) hours' prior notice during normal business hours during the ninety (90)
days following the respective delivery of the Operating Cost Report or the Tax
Report.  The results of any such inspection shall be kept strictly confidential
by Tenant and its agents, and Tenant and its certified public accountant must
agree, in their contract for such services, to such confidentiality restrictions
and shall specifically agree that the results shall not be made available to any
other tenant of the Building.  Unless Tenant sends to Landlord any written
exception to either such report within said ninety (90) day period, such report
shall be deemed final and accepted by Tenant.  Tenant shall pay the amount shown
on both reports in the manner prescribed in this Lease, whether or not Tenant
takes any such written exception, without any prejudice to such exception.  If
Tenant makes a timely exception, Landlord shall cause its independent certified
public accountant to issue a final and conclusive resolution of Tenant's
exception.  Tenant shall pay the cost of such certification unless Landlord's
original determination of annual Operating Costs or Taxes overstated the amounts
thereof by more than five percent (5%).

          (5)  Miscellaneous.  So long as Tenant is in default of any obligation
               -------------

     3.   PREPARATION AND CONDITION OF PREMISES; POSSESSION AND SURRENDER OF

PREMISES.
- -------- 

     A.   Condition of Premises.  Except to the extent of the Tenant
          ---------------------
Improvements item on the Schedule, and without limiting Landlord s duties under
other provisions of this Lease, Landlord is leasing the Premises to Tenant "as
is", without any obligation to alter, remodel, improve, repair or decorate any
part of the Premises.  Landlord shall cause the Premises to be completed in
accordance with the Tenant Improvement Agreement attached as Appendix C.

     B.   Tenant's Possession.  Tenant's taking possession on the Commencement
          -------------------
Date of any portion of the Premises shall be conclusive evidence that the
Premises was in good order, repair and condition, other than latent and other
defects which are not discoverable upon reasonable inspection by Tenant at the
time of taking possession.  If Landlord authorizes Tenant to take possession of
any part of the Premises prior to the Commencement Date for purposes of doing
business, all terms of this Lease shall apply to such pre-Term possession,
including Base Rent at the rate set forth for the First Lease 

                                       8
                                       -

Year in the Schedule prorated for any partial month. Notwithstanding the
foregoing, Tenant shall be granted access to the Premises thirty (30) days prior
to the Commencement Date for the purposes of installing Tenant s furniture,
fixtures and equipment.

     In the event that through no fault of Tenant, and subject to force majeure,
Landlord has not substantially completed (as defined in Appendix C) the Premises
in accordance with Appendix C by the Commencement Date, as Tenant s sole and
exclusive remedy, Landlord shall provide Tenant with two (2) days of Base Rent
abatement credit for each day of late delivery until the Premises are
substantially complete provided, however, that in the event that Premises are
not delivered within 120 days of the Commencement Date, Tenant shall have the
right to terminate this Lease.

     C.   Surrender.  Subject to Landlord's obligations set forth herein and
          ---------
paragraph 4E, throughout the Term, Tenant shall maintain, repair and replace the
Premises in their condition as of the Completion Date, loss or damage caused by
the elements, ordinary wear, and fire and other casualty excepted, and at the
termination of this Lease, or Tenant's right to possession, Tenant shall return
the Premises to Landlord in broom-clean condition.  To the extent Tenant fails
to perform either obligation, Landlord may, but need not, restore the Premises
to such condition and Tenant shall pay the cost thereof.

     4.   BUILDING AND LANDLORD REPAIR.
          ---------------------------- 

     Landlord shall furnish the services, repair and maintenance to the Premises
and Buildings ("Building Services"), unless otherwise stated herein, as follows:

     A.   Heating and Air Conditioning.   Landlord shall furnish heating and air
          ----------------------------
conditioning system to the Premises as part of the Building Shell to provide a
comfortable temperature, in Landlord's judgment, for normal business operations.
Tenant may install supplementary stand alone air conditioning units in the
Premises, if necessary to maintain comfortable temperature for normal business
operations, provided that such improvements by Tenant shall be of Tenant's sole
cost and expense, and subject to Landlord's reasonable prior approval and the
terms of Article 5 hereof.  Tenant shall pay to Landlord upon demand as
Additional Rent the cost of operation, repair and maintenance thereof.

     B.   Electricity. Landlord shall furnish to the Premises as part of the
          -----------
Building Shell sufficient electricity to operate normal office equipment.
Tenant shall not install or operate in the Premises any electrically operated
equipment or other machinery, other than business machines and equipment
normally employed for general office use (other than equipment installed in
Tenant's "equipment demo rooms", engineering laboratories and on the production
floor) which do not require high electricity consumption for operation.  If any
of Tenant's equipment requires electricity consumption in excess of the capacity
of the electrical system installed by Landlord in the Premises, all additional

                                       9
                                       -
<PAGE>
 
transformers, distribution panels and wiring that may be required to provide the
amount of electricity required for Tenant's equipment shall be installed by
Landlord at the cost and expense of Tenant except to the extent covered by the
Landlord Contribution.  Tenant shall pay the cost of electricity it consumes as
recorded by the electric meter serving the Premises directly to the electric
company.  In the event that the Premises are not separately metered, Tenant
shall be billed periodically by Landlord based upon such consumption or shall be
made part of the Operating Cost Share Rent.

     C.   Water.  Landlord shall furnish hot and cold tap water for drinking and
          -----

     D.   Janitorial Service.  Tenant shall provide, at its own cost and
          ------------------
expense, janitorial services to the Premises.  At Tenant's request, Landlord may
furnish janitorial to the Premises.  Tenant shall reimburse Landlord such costs
as Additional Rent.

     E.   Landlord's Repair Obligations.  Subject to Tenant's obligations set
          -----------------------------
forth in paragraph 5F below and Landlord's rights to reimbursement of costs and
expenses as set forth in this Lease, Landlord shall repair, maintain and
replace, as necessary, the Building shell, the roof, exterior walls and
structural parts of the Premises, and equipment and fixtures comprising the
Building Services (unless otherwise expressly excluded as set forth in this
paragraph 4).  Tenant shall pay to and reimburse Landlord for the cost and
expense of Landlord's obligations hereunder as Operating Costs, or if such
services are provided solely to Tenant and the Premises, Landlord shall invoice
Tenant and Tenant shall pay Landlord, as Additional Rent, the cost of such
services.  Notwithstanding the foregoing, Landlord shall not (i) be required to
make repairs necessitated by reason of the negligence or willful misconduct of
Tenant or anyone claiming under Tenant, by reason of the failure of Tenant to
perform or observe any conditions or agreements of this Lease, or by reason of
any improvements or alterations made by Tenant, or (ii) be liable to Tenant for
failure to make repairs as herein specifically required of it unless Tenant has
notified Landlord, in writing (except in emergencies) of the need for such
repairs and Landlord has failed to commence said repairs within ten (10)
business days following receipt of Tenant's notification.

     F.   Interruption of Services.  If any of the Building utilities systems,
          ------------------------
equipment or machinery provided or maintained by Landlord ceases to function
properly for any cause, Landlord shall use reasonable diligence to repair the
same promptly.  Landlord's inability to furnish, to any extent, the Building
Services set forth in this Section 4, or any cessation thereof resulting from
any causes, including any entry for repairs pursuant to this Lease, and any
renovation, redecoration or rehabilitation of any area of the Building shall not
render Landlord liable for damages to either person or property or for
interruption or loss to Tenant's business, nor be construed as an eviction of
Tenant, nor work an abatement of any portion of rent, nor relieve Tenant from
fulfillment 

                                      10
                                      --
<PAGE>
 
of any covenant or agreement hereof; provided, however, in the event that an
interruption of the Building Services set forth in this Section 4 to the extent
caused by Landlord's negligence or performance of its duties under this Lease
causes the Premises to be untenantable for a period of at least five (5)
consecutive business days, monthly Rent shall be abated proportionately.

     5.   ALTERATIONS AND REPAIRS BY TENANT.
          --------------------------------- 

     A.   Landlord's Consent and Conditions.
          --------------------------------- 

     Tenant shall not make any improvements or alterations to the Premises (the
"Work"), in excess of ten thousand dollars ($10,000) without in each instance
 ----
submitting plans to Landlord and obtaining Landlord's prior written consent,
which shall not be unreasonably withheld.  For purposes of this Section, the
term "Work" shall not include Tenant's furniture, fixtures or equipment.
Landlord will be deemed to be acting reasonably in withholding its consent for
any Work which (a) impacts the base structural components or systems of the
Building, (b) impacts any other tenant's premises, or (c) is visible from
outside the Premises, with the exception of antennas installed pursuant to
Section 6 hereof.  With respect to any consent required herein, Landlord shall
respond within ten (10) days.

     Tenant shall reimburse Landlord for actual costs incurred for review of the
plans and all other items submitted by Tenant.  Tenant shall pay for the cost of
all Work.  All Work shall become the property of Landlord upon its installation,
except for Tenant's trade fixtures and for items which Landlord requires Tenant
to remove at Tenant's cost at the termination of the Lease pursuant to Section
5E.

     The following requirements shall apply to all Work:

          (1)  Prior to commencement, Tenant shall furnish to Landlord building
permits, certificates of insurance satisfactory to Landlord, and, at Landlord's
request, security for payment of all costs.

          (2)  Tenant shall perform all Work so as to maintain peace and harmony
among other contractors serving the Project and shall avoid interference with
other work to be performed or services to be rendered in the Project.

          (3)  The Work shall be performed in a good and workmanlike manner,
meeting the standard for construction and quality of materials in the Building,
and shall comply with all insurance requirements and all applicable governmental
laws, ordinances and regulations ("Governmental Requirements").
                                   -------------------------

                                      --
<PAGE>
 
          (4)  Tenant shall perform all Work so as to minimize or prevent
disruption to other tenants, and Tenant shall comply with all reasonable
requests of Landlord in response to complaints from other tenants.

          (5)  Tenant shall perform all Work in compliance with Landlord's
"Policies, Rules and Procedures for Construction Projects" in effect at the time
the Work is performed.

          (6)  Tenant shall permit Landlord to supervise all Work.  Landlord may
charge a supervisory fee not to exceed five percent (5%) of labor, material, and
all other costs of the Work, if Landlord's employees or contractors perform the
Work.
 
          (7)  Upon completion, Tenant shall furnish Landlord with contractor's
affidavits and full and final statutory waivers of liens, as-built plans and
specifications, and receipted bills covering all labor and materials.

     B.   Damage to Systems.  If any part of the mechanical, electrical or other
          -----------------
systems in the Premises provided or maintained by landlord shall be damaged as a
result of Tenant's improvements or alterations, Tenant shall promptly notify
Landlord, and Landlord shall repair such damage.  Landlord may also at any
reasonable time make any repairs or alterations which Landlord deems necessary
for the safety or protection of the Project, or which Landlord is required to
make by any court or pursuant to any Governmental Requirement.  During any
period of Tenant's alteration or improvement of the Premises, Tenant shall at
its expense make all other repairs required as a result or caused by Tenant's
construction of alterations and improvements necessary to keep the Premises, and
Tenant's fixtures and personal property, in good order, condition and repair; to
the extent Tenant fails to do so, Landlord may make such repairs itself.  The
cost of any repairs made by Landlord on account of Tenant's default, or on
account of the mis-use or neglect by Tenant or its invitees, contractors or
agents anywhere in the Project, shall become Additional Rent payable by Tenant
on demand.

     C.   No Liens.  Tenant has no authority to cause or permit any lien or
          --------
encumbrance of any kind to affect Landlord's interest in the Project; any such
lien or encumbrance shall attach to Tenant's interest only.  If any mechanic's
lien shall be filed or claim of lien made for work or materials furnished to
Tenant, then Tenant shall at its expense within ten (10) days thereafter either
discharge or contest the lien or claim.  If Tenant contests the lien or claim,
then Tenant shall (i) within such ten (10) day period, provide Landlord adequate
security for the lien or claim, (ii) contest the lien or claim in good faith by
appropriate proceedings that operate to stay its enforcement, and (iii) pay
promptly any final adverse judgment entered in any such proceeding.  If Tenant
does not comply with these requirements, Landlord may discharge the lien or
claim, and the amount paid, as well as attorney's fees and other expenses
incurred by Landlord, shall become Additional Rent payable by Tenant on demand.

Landlord consents otherwise in writing, and (ii) shall at Landlord's option
either (a) be surrendered to Landlord with the Premises at the termination of

improvements which Landlord elects shall be removed by Tenant pursuant to
Section 5D, and any improvements to any portion of the Project other than the
Premises, provided, however, that Tenant is not required to remove any Initial
Improvements, Additional Improvements, Landlord's Work, or the skybridge.  If
Tenant does not timely remove such property, then Tenant shall be conclusively
presumed to have, at Landlord's election (i) conveyed such property to Landlord
without compensation or (ii) abandoned such property, and Landlord may dispose
of or store any part thereof in any manner at Tenant's sole cost, without
waiving Landlord's right to claim from Tenant all expenses arising out of 
Tenant's Sailure to remove the property, and without liability to Tenant or any
other person. Landlord shall have no duty to be a bailee of any such personal
property. If Landlord elects abandonment, Tenant shall pay to Landlord, upon
demand, any expenses incurred for disposition.

     F.   Tenant's Repair Obligation.  Subject to Landlord's obligations set
          --------------------------
forth in paragraph 4E, Tenant shall, throughout the term of this Lease and at

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

demonstration to customers, equipment testing and storage.  Tenant shall not

                                      --

Tenant shall not allow any inflammable or explosive liquids or materials to be

any other Tenant or with the operation of the Project by Landlord. Tenant shall
not permit any nuisance or waste upon the Premises, or allow any offensive noise
or odor in or around the Premises.

     If any governmental authority shall deem the Premises to be a "place of

comparable law as a result of Tenant's use, Tenant shall either modify its use
to cause such authority to rescind its designation or be responsible for any
alterations, structural or otherwise, required to be made to the Building or the
Premises under such laws.

     Tenant, its employees, agents, contractors or invitees shall be allowed
access to the building roof for the purpose of installing servicing, monitoring,

Section 3 and 5.

          --------------------------------------------
with all Governmental Regulations applicable to the design or construction of
the Premises, the Building shell, the Initial Improvements and the Additional
Improvements.  Tenant shall comply with all Governmental Requirements applying
to its use of the Premises.  Tenant shall also comply with all reasonable rules
established for the Project from time to time by Landlord.  The present rules
and regulations are contained in Appendix B.  Failure by another tenant to
comply with the rules or failure by Landlord to enforce them shall not relieve
Tenant of its obligation to comply with the rules or make Landlord responsible
to Tenant in any way.  Landlord shall use reasonable efforts to apply the rules
and regulations uniformly with respect to Tenant and tenants in the Project
under leases containing rules and regulations similar to this Lease.  In the
event of alterations and repairs performed by Tenant, Tenant shall comply with
the provisions of Section 5 of this Lease and also landlord s Policies, Rules
and Regulations for Construction Projects".

party may terminate this Lease effective as of the date of the taking.  In the
event that seventy five percent (75%) or more of the Project is taken without
affecting the Premises, then Landlord may terminate this Lease as of the date of
such taking.  Rent shall abate from the date of the taking in proportion to any

cure its failure within the ten (10) day period but cannot reasonably complete
its cure within such period, then, so long as Tenant continues 

                                      19
                                      --

stayed within seven days after entry;

          (2)  Tenant becomes insolvent or bankrupt, does not generally pay its
debts as they become due, or admits in writing its inability to pay its debts,
or makes a general assignment for the benefit of creditors;

     13.  LANDLORD REMEDIES.
          ----------------- 

     A.   Termination of Lease or Possession.  If Tenant defaults, Landlord may
          ----------------------------------
elect by notice to Tenant either to terminate this Lease or to terminate
Tenant's possession of the Premises without terminating this Lease.  In either
case, Tenant shall immediately vacate the Premises and deliver possession to
Landlord, and Landlord may repossess the Premises and may, at Tenant's sole
cost, remove any of Tenant's signs and any of its other property, without
relinquishing its right to receive Rent or any other right against Tenant.

     B.   Lease Termination Damages.  If Landlord terminates the Lease, Tenant
          -------------------------
shall pay to Landlord all Rent due on or before the date of termination, plus
Landlord's reasonable estimate of the aggregate Rent that would have been
payable from the date of termination through the Termination Date, reduced by
the rental value of the Premises calculated as of the date of termination for
the same period, taking into account reletting expenses and market concessions,
both discounted to present value at the rate of five percent (5%) per annum.  If
Landlord shall relet any part of the Premises for any part of such period before
such present value amount shall have been paid by Tenant or finally determined
by a court, then the amount of Rent payable pursuant to such reletting (taking
into account any concessions) shall be deemed to be the reasonable rental value
for that portion of the Premises relet during the period of the reletting.

     C.   Possession Termination Damages.  If Landlord terminates Tenant's right
          ------------------------------
to possession without terminating the Lease and Landlord takes possession of the
Premises itself, Landlord may relet any part of the Premises for such Rent, for
such time, and upon such terms as Landlord in its sole discretion shall
determine, without any obligation to do so prior to renting other vacant areas
in the Building.  Any proceeds from reletting the Premises shall first be
applied to the expenses of reletting, including redecoration, repair,
alteration, advertising, brokerage, legal, and other reasonably necessary
expenses.  If the 

                                      20
                                      --
<PAGE>
 
reletting proceeds after payment of expenses are insufficient to pay the full
amount of Rent under this Lease, Tenant shall pay such deficiency to Landlord
monthly upon demand as it becomes due. Any excess proceeds shall be retained by
Landlord.

     D.   Landlord's Remedies Cumulative.  All of Landlord's remedies under this
          ------------------------------
Lease shall be in addition to all other remedies Landlord may have at law or in
equity.  Waiver by Landlord of any breach of any obligation by Tenant shall be
effective only if it is in writing, and shall not be deemed a waiver of any
other breach, or any subsequent breach of the same obligation.  Landlord's
acceptance of payment by Tenant shall not constitute a waiver of any breach by
Tenant, and if the acceptance occurs after Landlord's notice to Tenant, or
termination of the Lease or of Tenant's right to possession, the acceptance
shall not affect such notice or termination.  Acceptance of payment by Landlord
after commencement of a legal proceeding or final judgment shall not affect such
proceeding or judgment.  Landlord may advance such monies and take such other
actions for Tenant s account as reasonably may be required to cure or mitigate
any default by Tenant.  Tenant shall immediately reimburse Landlord for any such
advance, and such sums shall bear interest at the default interest rate until
paid.

     E.   WAIVER OF TRIAL BY JURY.  EACH PARTY WAIVES TRIAL BY JURY IN THE EVENT
          -----------------------
OF ANY LEGAL PROCEEDING BROUGHT BY THE OTHER IN CONNECTION WITH THIS LEASE.
EACH PARTY SHALL BRING ANY ACTION AGAINST THE OTHER IN CONNECTION WITH THIS
LEASE IN A FEDERAL OR STATE COURT LOCATED IN WASHINGTON, CONSENTS TO THE
JURISDICTION OF SUCH COURTS, AND WAIVES ANY RIGHT TO HAVE ANY PROCEEDING
TRANSFERRED FROM SUCH COURTS ON THE GROUND OF IMPROPER VENUE OR INCONVENIENT
FORUM.

     F.   Litigation Costs.  Tenant shall pay Landlord's reasonable attorneys'
          ----------------
fees and other costs in any action brought to enforce this Lease.

     14.  SURRENDER.  Upon termination of this Lease or Tenant's right to
          ---------
possession, Tenant shall return the Premises to Landlord in good order and
condition, ordinary wear and casualty damage excepted.  If Landlord requires
Tenant to remove any alterations, then Tenant shall remove the alterations in a
good and workmanlike manner and restore the Premises to its condition prior to
their installation.

     15.  HOLDOVER.  If Tenant retains possession of any part of the Premises
          --------
after the Term, Tenant shall become a month-to-month tenant for the entire
Premises upon all of the terms of this Lease as might be applicable to such
month-to-month tenancy, except that Tenant shall pay all of Base Rent, Operating
Cost Share Rent and Tax Share Rent at one hundred twenty five percent (125%) of
the rate in effect immediately prior to such holdover, computed on a monthly
basis for each full or partial month Tenant remains in possession.  Tenant shall
also pay Landlord all of Landlord's 

                                       21
<PAGE>
 
direct and consequential damages if such holdover is without consent. No
acceptance of Rent or other payments by Landlord under these holdover provisions
shall operate as a waiver of Landlord's right to regain possession or any other
of Landlord's remedies.

     16.  SUBORDINATION TO GROUND LEASES AND MORTGAGES.
          -------------------------------------------- 

     A.   Subordination.  Subject to Section 16B, this Lease shall be 
          -------------
subordinate to any present or future ground lease or mortgage respecting the
Project, and any amendments to such ground lease or mortgage, at the election of
the ground lessor or mortgagee as the case may be, effected by notice to Tenant
in the manner provided in this Lease. The subordination shall be effective upon
such notice, but at the request of Landlord or ground lessor or mortgagee,
Tenant shall within ten (10) days of the request, execute and deliver to the
requesting party any reasonable documents provided to evidence the
subordination.

     B.   Termination of Ground Lease or Foreclosure of Mortgage.  If any ground
          ------------------------------------------------------
lease is terminated or mortgage foreclosed or deed in lieu of foreclosure given
and the ground lessor, mortgagee, or purchaser at a foreclosure sale shall
thereby become the owner of the Project, Tenant shall attorn to such ground
lessor or mortgagee or purchaser without any deduction or setoff by Tenant, and
this Lease shall continue in effect as a direct lease between Tenant and such
ground lessor, mortgagee or purchaser. The ground lessor or mortgagee or
purchaser shall be liable as Landlord only during the time such ground lessor or
mortgagee or purchaser is the owner of the Project. At the request of Landlord,
ground lessor or mortgagee, Tenant shall execute and deliver within ten (10)
days of the request any document furnished by the requesting party to evidence
Tenant's agreement to attorn.
 
     C.   Security Deposit.  Any ground lessor or mortgagee shall be responsible
          ----------------
for the return of any security deposit by Tenant only to the extent the security
deposit is received by such ground lessor or mortgagee.

     D.   Notice and Right to Cure.  The Project is subject to any ground lease
          ------------------------
and mortgage identified with name and address of ground lessor or mortgagee in
Appendix D to this Lease (as the same may be amended from time to time by
written notice to Tenant). Tenant agrees to send by registered or certified mail
to any ground lessor or mortgagee identified either in such Appendix or in any
later notice from Landlord to Tenant a copy of any notice of default sent by
Tenant to Landlord. If Landlord fails to cure such default within the required
time period under this Lease, but ground lessor or mortgagee begins to cure
within ten (10) days after such period and proceeds diligently to complete such
cure, then ground lessor or mortgagee shall have such additional time as is
necessary to complete such cure, including any time necessary to obtain
possession if possession is necessary to cure, and Tenant shall not begin to
enforce its remedies so long as the cure is being diligently pursued.

                                       22

     E.   Definitions.  As used in this Section 16, "mortgage" shall include
          -----------

the mortgagee of any ground lessee, and "ground lessor", "mortgagee", and
"purchaser at a foreclosure sale" shall include, in each case, all of its

     17.  ASSIGNMENT AND SUBLEASE.
          ----------------------- 

     A.   In General.  Tenant shall not, without the prior consent of Landlord
          ----------
in each case, (i) make or allow any assignment or transfer, by operation of law
or otherwise, of any part of Tenant's interest in this Lease, (ii) grant or
allow any lien or encumbrance, by operation of law or otherwise, upon any part
of Tenant's interest in this Lease, (iii) sublet any part of the Premises, or
(iv) permit anyone other than Tenant and its employees to occupy any part of the
Premises. Tenant shall remain primarily liable for all of its obligations under
this Lease, notwithstanding any assignment or transfer. No consent granted by
Landlord shall be deemed to be a consent to any subsequent assignment or
transfer, lien or encumbrance, sublease or occupancy. Tenant shall pay
reasonable Landlord's attorneys' fees and other expenses incurred in connection
with any consent requested by Tenant or in reviewing any proposed assignment or
subletting. Any assignment or transfer, grant of lien or encumbrance, or
sublease or occupancy without Landlord's prior written consent shall be void.

     B.   Landlord's Consent.  Landlord will not unreasonably withhold its
          ------------------
consent to any proposed assignment or subletting. It shall be reasonable for
Landlord to withhold its consent to any assignment or sublease if (i) Tenant is
in default under this Lease, (ii) the proposed assignee or sublessee is a tenant
in the Project and Landlord has appropriate available space in the Project,
(iii) the financial condition, nature of business, and character of the proposed
assignee or subtenant are not all reasonably satisfactory to Landlord, (iv) in
the reasonable judgment of Landlord the purpose for which the assignee or
subtenant intends to use the Premises (or a portion thereof) is not in keeping
with Landlord's standards for the Building or are in violation of the terms of
this Lease or any other leases in the Project. The foregoing shall not exclude
any other reasonable basis for Landlord to withhold its consent.

     C.   Procedure.  Tenant shall notify Landlord of any proposed assignment or
          ---------
sublease at least thirty (30) days prior to its proposed effective date. The
notice shall include the name and address of the proposed assignee or subtenant,
its corporate affiliates in the case of a corporation and its partners in a case
of a partnership, an execution copy of the proposed assignment or sublease, and
sufficient information to permit Landlord to determine the financial condition
and character of the proposed assignee or subtenant. As a condition to any
effective assignment of this Lease, the assignee shall execute and deliver in
form satisfactory to Landlord at least fifteen (15) days prior to the effective
date of the assignment, an assumption of all of the obligations of Tenant under
this Lease. As a condition to any effective sublease, subtenant shall execute
and deliver in form satisfactory to Landlord at least fifteen (15) days prior to
the

                                      23
                                      --
<PAGE>

obligations under this Lease, and at Landlord's option, an agreement (except for
the economic obligations which subtenant will undertake directly to Tenant) to
attorn to Landlord under the terms of the sublease in the event this Lease
terminates before the sublease expires.

     D.   Change of Ownership.  Any direct or indirect change in 50% or more of
          -------------------
the ownership interest in Tenant shall constitute an assignment of this Lease;
provided, however, that Landlord hereby consents to any such assignment that is
in connection with (i) transfer of shares between existing shareholders, (ii)
redemption of shares by Tenant, or (iii) a public offering of Tenant s stock
under the Securities Act of 1933, as amended. Notwithstanding Landlord's prior
consent to the foregoing, Tenant shall provide Landlord with written notice
required hereunder.

     E.   Excess Payments.  If Tenant shall assign this Lease or sublet any part
          ---------------
of the Premises for consideration in excess of the pro-rata portion of Rent
applicable to the space subject to the assignment or sublet, then Tenant shall
pay to Landlord as Additional Rent 50% of any such excess immediately upon
receipt.

     18.  CONVEYANCE BY LANDLORD.  If Landlord shall at any time transfer its
          ---------------------- 
interest in the Project or this Lease, provided that the transferee shall
expressly assume in writing all duties of Landlord in this Lease, Landlord shall
be released of any obligations accruing after such transfer, except the
obligation to return to Tenant any security deposit not delivered to its
transferee, and Tenant shall look solely to Landlord's successors for
performance of such obligations. This Lease shall not be affected by any such
transfer.

     19.  ESTOPPEL CERTIFICATE.  Each party shall, within ten (10) days of
          --------------------
receiving a request from the other party, execute, acknowledge in recordable
form, and deliver to the other party or its designee a certificate stating,
subject to a specific statement of any applicable exceptions, that the Lease as
amended to date is in full force and effect, that the Tenant is paying Rent and
other charges on a current basis, and that to the best of the knowledge of the
certifying party, the other party has committed no uncured defaults and has no
offsets or claims. The certifying party may also be required to state the date
of commencement of payment of Rent, the Commencement Date, the Termination Date,
the Base Rent, the current Operating Cost Share Rent and Tax Share Rent
estimates, the status of any improvements required to be completed by Landlord,
the amount of any security deposit, and such other matters as may be reasonably
requested. Failure to deliver such statement within the time required shall be
conclusive evidence against the non-certifying party that this Lease, with any
amendments identified by the requesting party, is in full force and effect, that
there are no uncured defaults by the requesting party, that not more than one
month's Rent has been paid in advance, that the non-certifying party has not
paid any security deposit, and that the non-certifying party has no claims or
offsets against the requesting party.

     20.  SECURITY DEPOSIT.  Tenant shall arrange for the issuance and delivery
          ----------------
to Landlord on the date of this Lease, as security for the performance of all of
its obligations of Tenant hereunder an irrevocable, standby letter of credit
(the "Letter of Credit") from Silicon Valley Bank, Imperial Bank or such other
commercial bank of Tenant's choosing and reasonably acceptable and in form and
content reasonably satisfactory to Landlord, in the amount set forth on the
Schedule. Upon the execution of this Lease, Tenant shall deliver a Letter of
Credit in the amount of $1,000.000. The amount of the Letter of Credit shall be
increased by $1,000,000 on January 1, 1998 and then by $500,000 on the
Commencement Date. If Tenant defaults under this Lease, Landlord may use any
part of the Letter of Credit or Security Deposit to make any defaulted payment,
to pay for Landlord's cure of any defaulted obligation, or to compensate
Landlord for any loss or damage resulting from any default. Landlord agrees to
release the Letter of Credit upon satisfaction of all of the following
conditions: (i) Tenant s Operating Income from continuing operations under GAAP
exceeds $500,000 for four consecutive quarters; (ii) Tenant s cash and
receivables are a minimum of $10,000,000; (iii) a current ratio (defined as
current assets divided by current liabilities) of at least two times; and (iv)
Tenant has delivered a certificate of the President of Tenant representing and
warranting the foregoing and the amount of one month s rent as a Security
Deposit. Landlord may keep the Security Deposit, if cash, in its general funds
and shall not be required to pay interest to Tenant on the deposit amount. If
Tenant shall perform all of its obligations under this Lease and return the
Premises to Landlord at the end of the Term, Landlord shall return all of the
remaining Security Deposit to Tenant within thirty (30) days after the end of
the Term. The Security Deposit shall not serve as an advance payment of Rent or
a measure of Landlord's damages for any default under this Lease.

     If Landlord transfers its interest in the Project or this Lease, Landlord
shall transfer the Security Deposit to its transferee. Upon such transfer,
Landlord shall have no further obligation to return the Security Deposit to
Tenant, and Tenant's right to the return of the Security Deposit shall apply
solely against Landlord's transferee.

     21.  FORCE MAJEURE.  Landlord shall not be in default under this Lease to
          -------------               
the extent Landlord is unable to perform any of its obligations on account of
any strike or labor problem, energy shortage, governmental pre-emption or
prescription, national emergency, or any other cause of any kind beyond the
reasonable control of Landlord ("Force Majeure"). This Section 21 shall not
limit Tenant's rights to any abatement of rent expressly allowed in this Lease.

                                EXTENSION OPTION

     EXTENSION OPTION.  Subject to Subsection B below, Tenant may at its option
     ----------------
extend the Term of this Lease for TWO (2) successive periods of FIVE (5) YEARS
each.  Each such period is called a "Renewal Term", and the first such FIVE (5)
                                     ------------
YEAR period is called the "First Renewal Term" and the second such five (5) year
                           ------------------  
period is called the "Second Renewal Term".  Each Renewal Term shall be upon the
                      -------------------
same terms contained in this Lease except for the payment of Base Rent during
the Renewal Term; and any reference in the Lease to the "Term" of the Lease
shall be deemed to include any Renewal Term and apply thereto, unless it is
expressly provided otherwise.  Tenant shall have no additional extension
options.

     A.   The Base Rent during a Renewal Term shall be the greater of (i) the
Base Rent applicable to the last day of the final Lease Year prior to the
applicable Renewal Term, or (ii) 100% of the Market Rate (defined hereinafter)
for such space for a term commencing on the first day of the Renewal Term.
"Market Rate" shall mean the then prevailing market rate for a five (5) year
 -----------
term commencing on the first day of the Renewal Term for tenants of comparable
size and creditworthiness for comparable buildings in the general vicinity of
the Project.  Determination of the Market Rate shall include, without
limitation, then current applicable market conditions such as rent abatements,
tenant allowances, cash incentives, broker commissions, Tenant's use,
availability of space in the Redmond area, the build out of the Premises and
such additional factors as might reasonably be considered in determining the
Market Rate.

     B.   To exercise any option, Tenant must deliver a binding notice to
Landlord not less than twelve (12) months prior to the expiration of the initial
Term of this Lease, or the first Renewal Term, as the case may be. Thereafter,
the Market Rate for the particular Renewal Term shall be calculated pursuant to
Subsection C below and Landlord shall inform Tenant of the Market Rate.  Such
calculations shall be final and shall not be recalculated at the actual
commencement of such Renewal Term.  If Tenant fails to timely give its notice of
exercise, Tenant will be deemed to have waived its option to extend.

     C.   Market Rate shall be determined as follows:

          (i) If Tenant provides Landlord with its binding notice of exercise
     pursuant to Subsection B above, then at some point between thirteen (13)
     and eleven (11) months prior to the commencement of the applicable Renewal
     Term (or, at Landlord s election, at an earlier point), Landlord shall
     calculate and inform Tenant of the Market Rate.  At the same time Landlord
     shall provide to Tenant in writing supporting information used by Landlord
     to calculate the Market Rate including rental rates and lease terms on
     comparable buildings, which Landlord 

                                  APPENDIX G
                                  Page 1 of 2
<PAGE>
 
     shall identify by name and location. If Tenant rejects the Market Rate as
     calculated by Landlord, Tenant shall inform Landlord of its rejection
     within twenty (20) days after Tenant s receipt of Landlord s calculation,
     and Landlord and Tenant shall commence negotiations to agree upon the
     Market Rate. If Tenant fails to timely reject Landlord s calculation of the
     Market Rate it will be deemed to have accepted such calculation. If
     Landlord and Tenant are unable to reach agreement within twenty-one (21)
     days after Landlord s receipt of Tenant s notice of rejection, then the
     Market Rate shall be determined in accordance with (ii) below.

          (ii)  If Landlord and Tenant are unable to reach agreement on the
     Market Rate within said twenty-one (21) day period, then within seven (7)
     days, Landlord and Tenant shall each simultaneously submit to the other in
     a sealed envelope its good faith estimate of the Market Rate.  If the
     higher of such estimates is not more than one hundred five percent (105%)
     of the lower, then the Market Rate shall be the average of the two.
     Otherwise, the dispute shall be resolved by arbitration in accordance with
     (iii) below.

          (iii) Within seven (7) days after the exchange of estimates, the
     parties shall select as an arbitrator an independent MAI appraiser with at
     least five (5) years of experience in appraising office space in the
     metropolitan area in which the Project is located (a "Qualified
     Appraiser").  If the parties cannot agree on a Qualified Appraiser, then
     within a second period of seven (7) days, each shall select a Qualified
     Appraiser and within ten (10) days thereafter the two appointed Qualified
     Appraisers shall select a third Qualified Appraiser and the third Qualified
     Appraiser shall be the sole arbitrator.  If one party shall fail to select
     a Qualified Appraiser within the second seven (7) day period, then the
     Qualified Appraiser chosen by the other party shall be the sole arbitrator.
 
          (iv)  Within twenty-one (21) days after submission of the matter to
     the arbitrator, the arbitrator shall determine the Market Rate by choosing
     whichever of the estimates submitted by Landlord and Tenant the arbitrator
     judges to be more accurate. The arbitrator shall notify Landlord and Tenant
     of its decision, which shall be final and binding. If the arbitrator
     believes that expert advice would materially assist him, the arbitrator may
     retain one or more qualified persons to provide expert advice. The fees of
     the arbitrator and the expenses of the arbitration proceeding, including
     the fees of any expert witnesses retained by the arbitrator, shall be paid
     by the party whose estimate is not selected. Each party shall pay the fees
     of its respective counsel and the fees of any witness called by that party.

     D.   Tenant's option to extend this Lease is subject to the conditions
that:  (i) on the date that Tenant delivers its binding notice exercising an
option to extend, Tenant is

and cure periods.

     1.   EXPANSION OPTION.  Subject to the terms and conditions of this
          ----------------  
paragraph, Landlord hereby grants to Tenant an option (the "Option") to lease
Building 6 located in the Project as shown on Exhibit A attached hereto (the
"Expansion Space").  To exercise the Option, Tenant must deliver a binding
written notice to Landlord of its intent to lease the Expansion Space on or
before May 1, 1999.  In the notice of intent to lease, Tenant shall specify the
date on which the Landlord shall deliver the Expansion Space to Tenant, which
date (i) shall not be less than nine (9) months from the date of the notice, and
(ii) shall be no later than February 1, 2000 .  Tenant hereby acknowledges that
time is of the essence with respect to delivery of the notice and that failure
to deliver such written notice to Landlord within the time required shall result
in the termination of Tenant s Option to lease the Expansion Space.  Upon proper
exercise of Tenant s Option, Landlord shall deliver to Tenant the Expansion
Space on the specific delivery date, unless otherwise mutually agreed by
Landlord and Tenant.  Tenant s notice of its election to exercise its Option for
the Expansion Space shall be subject to the following conditions:  (a) the Lease
shall be in full force and effect at the time of the exercise of such Option;
and (b) Tenant shall not be in default (subject to any notice and cure periods)
under the Lease.

     Tenant s lease of the Expansion Space shall be on the same terms and
conditions of this Lease of the Premises, including, without limitation, at the
rental rates paid at the time of such election for the Premises and, except for
Extension Options without further extension of the term of the Lease (it being
the intent of the parties that the lease of the Expansion Space shall be co-
terminus with the lease of the Premises).  Landlord and Tenant hereby agree to
execute an Amendment to Lease evidencing the lease of the Expansion Space in
form consistent with the terms hereof and satisfactory to the parties.  Landlord
shall deliver to Tenant the Expansion Space in a similar condition and terms as
the Premises were delivered to Tenant, including, Landlord s work and the Tenant
improvement allowance set forth in the Lease for the initial Premises.

     2.   LETTER OF CREDIT.  Section 12 of the Lease is hereby supplemented and

breach. Seller shall promptly investigate such breach and advise the Company of
Seller's planned corrective action. Thereafter, Seller shall promptly repair or

Company. If such breach of warranty has not been corrected to the Company's
satisfaction within a reasonable time (not to exceed thirty (30) days from the

addition to all other rights and remedies provided by law or this Agreement,

11.  TAXES

except state sales and use taxes, which shall be added as applicable and stated
as separate items on the invoice applicable to each delivery of Products.

12.  INFRINGEMENT INDEMNITY

     a.   Seller shall defend the Company against (or, at its option, settle) a
claim that the Products supplied hereunder infringe a United States patent or
copyright provided that  (i) the Company promptly notifies Seller in writing of
the claim, (ii) the Company gives Seller full opportunity and authority to
assume sole control of the defense and all related settlement negotiations, and
(iii) the Company gives Seller information and assistance for the defense (the
Company will be reimbursed for reasonable costs and expenses incurred in
rendering such assistance, against receipt of invoices therefor).  Subject to
the conditions and limitations of liability stated in this Agreement, Seller
shall indemnify and hold harmless the Company from all payments, which by final
judgments in such suits, may be assessed against the Company on account of such
alleged infringement and shall pay resulting settlements, costs (including
reasonable attorneys' fees) and damages finally awarded against the Company by a
court of law.

     b.   The Company agrees that if the Products become, or in Seller's opinion
are likely to become, the subject of such a claim, the Company will permit
Seller, at its option and expense, either to procure the right for the Company
to continue using such Products or to replace or modify same so that they become
non-infringing, and, if neither of the foregoing alternatives is available on
terms which are acceptable to Seller, the Company shall at the written request
of Seller, return the infringing or potentially infringing Products. The Company
shall receive a refund of the prorated undepreciated portion of the Purchase
Price actually paid by the Company to Seller for the returned portion of the
Products. The Purchase Price shall be depreciated over a five (5) year period.

     c.   Seller disclaims any and all liability for any claim of patent or
copyright infringement (i) based upon adherence to specifications, designs or
instructions furnished by the Company, (ii) based upon the combination,
operation or use of any Products supplied hereunder with products, software or
data not supplied by Seller, or (iii) based upon alteration of the Products or
modification of any Software made by any party other than Seller.

2.   SYSTEM DESCRIPTION

     2.1   Introduction
     The Spotlight Multibeam Antenna Platform (SMAP) brings enhanced performance
     to existing cellular technology. The system replaces the existing antenna
     components at a cell site with a high performance antenna array coupled to
     an RF switch matrix and control system. This upgrade provides a
     dramatically improved carrier-to-interference ratio (C/I) and is the basis
     for many other performance enhancements, such as improved audio quality,
     extended range and greater traffic capacity.

     2.2   General System Overview
     The SMAP provides the necessary hardware and software to allow the most
     appropriate narrow beam antennas (2 receive paths and 1 transmit path) to
     be connected to base station RCUs. The major subsystem components which
     make up the SpotLight Multibeam Antenna Platform (SMAP) including antennas,
     RF switch matrix, and controller are depicted in Figure 1.

For purposes of uniformity and brevity, references to Agreement or to an Exhibit
shall refer to the Purchase Agreement to which this document is Exhibit E and to
the other Exhibits to that Agreement.  All definitions set forth in the
Agreement shall apply hereto.

1.   SCOPE

     Pursuant to the above-identified Agreement, Software will be delivered by
     Seller to Company for use with the Products according to the terms of the
     Agreement and this Exhibit. Company shall then become a licensee with
     respect to such Software.

2.   LICENSING GRANT

     2.1  Concurrent with execution of the Agreement, Seller grants to Company a
          revocable, non-exclusive and non-transferable license under Seller's
          applicable proprietary rights to use Software delivered to Company
          hereunder in accordance with the terms and conditions set forth
          herein.

     2.2  Company agrees to pay the Licensing Fees for the right to use the
          Software and features and for any support thereof as set forth in
          Exhibit A (Price List) or in an Amendment thereto.

          including, but not limited to, substituted products, or products not
          owned by Company, or products located at a location other than the
          site specified in the Order.

     3.3  The License granted to Company in Section 2 is personal and may not be
          transferred to another product or site without the written consent of
          Seller.
<PAGE>
 
     3.4  To the extent specified in Exhibit A or an Amendment thereto and
          provided Company has paid any applicable licensing fees, Company shall
          have the right to use features in accordance with the terms of this
          Exhibit. Company acknowledges that the Software may contain therein
          several additional features which are each covered by separate
          licensing fees. Company agrees not to use, and the license
          specifically does not extend to, such additional features unless they
          are specified in Exhibit A or an amendment thereto and provided
          Company has paid the applicable licensing fees for such additional
          features.

     3.5  The Software is subject to laws protecting trade secrets, know-how,
          confidentiality and copyright.

     3.6  Company shall not translate, modify, adapt, decompile, disassemble, or
          reverse engineer the Software or any portion thereof.

     3.7  Unless otherwise expressly agreed by Seller, Company shall not permit
          its directors, officers, employees or any other person under its
          direct or indirect control, to write, develop, produce, sell, or
          license any software that performs the same functions as the Software
          by means directly attributable to access to the Software (e.g. reverse
          engineering or copying).

     3.8  Company shall not export the Software from the United States without
          the written permission of Seller. If written permission is granted for
          export of the Software, then Company shall comply with all U.S. laws
          and regulations for such exports and shall hold Seller harmless,
          including legal fees and expenses for any violation or attempted
          violation of the U.S. export laws.

4.   RIGHT TO COPY, PROTECTION AND SECURITY

     4.1  Software provided hereunder may be copied (for back-up purposes only)
          in whole or in part, in printed or machine-readable form for Company's
          internal use only, provided, however, that no more than two (2)
          printed copies and two (2) machine-readable copies shall be in
          existence at any one time without the prior written consent of Seller,
          other than copies resident in the Products.

     4.2  With reference to any copyright notice of Seller associated with
          Software, Company agrees to include the same on all copies it makes in
          whole or in part. Seller's copyright notice may appear in any of
          several forms, including machine-readable form. Use of a copyright
          notice on the Software does not imply that such has been published or
          otherwise made generally available to the public.

     4.3  Company agrees to keep confidential, in accordance with the terms of
          the Agreement, and not provide or otherwise make available in any form
          any Software or its contents, or any portion thereof, or any
          documentation pertaining to the Software, to any person other than
          employees of Company or Seller.

     4.4  Software, including features is the sole and exclusive property of
          Seller and no title or ownership rights to the Software or any of its
          parts, including documentation, is transferred to Company.

     4.5  Company acknowledges that it is the responsibility of Company to take
          all reasonable measures to safeguard Software and to prevent its
          unauthorized use or duplication.

<PAGE>
 
5.   REMEDIES

     Company acknowledges that violation of the terms of this Exhibit or the
     Agreement shall cause Seller irreparable harm for which monetary damages
     may be inadequate, and Company agrees that Seller may seek temporary or
     permanent injunctive relief without the need to prove actual harm in order
     to protect Seller's interests.

6.   TERM

     Unless otherwise terminated pursuant to Section 7 herein, the term of the
     license granted pursuant to Section 2 herein shall be co-extensive with the
     term of any licensing and/or maintenance fees paid by Company to Seller
     pursuant to Exhibit A or an Amendment thereto.

7.   TERMINATION

     7.1  The license granted hereunder may be terminated by Company upon one
          (1) month's prior written notice.

     7.2  Seller may terminate the license granted hereunder if Company is in
          default of any of the terms and conditions of the Agreement or

          Product. The warranties in this Agreement are given in lieu of all
          other warranties express or implied which are specifically excluded,
          including, without limitation, implied warranties of merchantibility
          and fitness for a particular purpose.

     b.   If Customer believes that there is a breach of any warranty set forth
          herein, Customer will notify Seller, setting forth in writing the
          nature of the claimed breach. Seller shall promptly investigate such
          breach and advise Customer of Seller's planned corrective action.

          be deemed to have been placed into operation and to be functioning
          properly within 30 days of receipt by Customer unless Seller is
          otherwise notified in writing of non-operation by Customer) or (ii)
          the balance of the remaining warranty period, whichever period of time
          is longer. Such action on the part of Seller shall be the full extent
          of Seller's liability and Customer's exclusive remedy hereunder.

     c.   This warranty is void if (i) the Product is used in other than its
          normal and customary manner; (ii) the Product has been subject to
          misuse, accident, neglect or damage; (iii) the Product has been
          installed, optimized or moved from its original installation site by
          any person other than Seller or a person who has been trained by
          Seller to provide such services; or (iv) unauthorized alterations or
          repairs have been made, or unapproved parts used in the equipment.

          regarding its Product Maintenance Program to be set forth in Exhibit G
          hereof and to be completed January 15, 1998. The Product Maintenance

          and shall use best efforts to pay by wire transfer the amount due
          within fifteen (15) days of the date of the invoices rendered pursuant

          any other taxes applicable to the Products and Services outside the
          United States provided by the Seller pursuant to this Agreement. When
          Seller is required by law to collect such taxes, 100% thereof will be
          added to invoices as separately stated charges and paid by Customer in
          accordance with this section.

     g.   If Customer disputes any invoices rendered or amount paid, Customer
          will so notify Seller, and the parties will use their reasonable
          efforts to resolve such dispute expeditiously. [***].

9.   INFRINGEMENT INDEMNITY

     a.   Seller shall defend Customer against (or, at its option, settle) a
          claim that the Products supplied hereunder infringe a United States

          Seller in writing of the claim, (ii) Customer gives Seller full
          opportunity and authority to assume sole control of the defense and
          all related settlement negotiations, and (iii) Customer gives Seller
          information and assistance for the defense (Customer will be
          reimbursed for reasonable costs and expenses incurred in rendering
          such assistance, against receipt of invoices therefor). Subject to the
          conditions and limitations of liability stated in this Agreement,
          Seller shall indemnify and hold harmless Customer from all payments,
          which by final judgments in such suits, may be assessed against
          Customer on account of such alleged infringement and shall pay
          resulting settlements, costs and damages finally awarded against
          Customer by a court of law.

      WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH

<PAGE>
 
     b.   Customer agrees that if the Products become, or in Seller's opinion
          are likely to become, the subject of such a claim, Customer will
          permit Seller, at its option and expense, either to procure the right
          for Customer to continue using such Products or to replace or modify
          same so that they become non-infringing, and, if neither of the
          foregoing alternatives is available on terms which are acceptable to
          Seller, Customer shall at the written request of Seller, return the
          infringing or potentially infringing Products. Customer shall receive
          a refund of the prorated undepreciated portion of the Purchase Price
          actually paid by Customer to Seller for the returned portion of the
          Products. The Purchase Price shall be depreciated over a seven (7)
          year period.

     c.   Seller shall have no obligation to Customer with respect to any claim
          of patent or copyright infringement which is based upon or related to
          (i) adherence to customized specifications, designs or instructions
          furnished by Customer, (ii) the interconnection or interface of any
          Products supplied hereunder with base station products or software not
          approved by Seller (such products approved by Seller are set forth in
          Exhibit B, section 2.2.7.), or (iii) the alteration of the Products or
          modification of any Software made by any party other than Seller.

contractor and not as the agent or employee of Customer.

Seller shall indemnify Customer, its employees and directors, and each of them,
against any loss, cost, damage, claim, expense or liability, including but not
limited to liability as a result of injury to or death of any person or damage

connection with the performance of this Agreement and directly caused, in whole
or in part, by the acts or omissions, negligent or otherwise, of Seller or a
contractor or an agent of Seller or an employee of anyone of them, except where
such loss, cost, damage, claim, expense or liability arises from the sole
negligence or willful misconduct of Customer or its employees. Seller shall, at
its own expense, defend any suit asserting a claim for any loss, damage or
liability specified above, and Seller shall pay any costs and attorneys' fees
that may me incurred by Customer in connection with any such claim or suit or in
enforcing the indemnity granted above, provided that Seller (i) is given prompt
notice of any such claim or suit and (ii) full opportunity to assume control of

17.  GOVERNING LAW; DISPUTE RESOLUTION

     a.   This Agreement and each Purchase Order shall be construed in
          accordance with the internal laws of the State of New York, without

          succeeded in negotiating a resolution of the dispute within ten (10)
          days after the first meeting, then the dispute will be resolved by
          nonbinding mediation in a mutually agreed location and to be conducted
          in English by a mutually agreed upon non-affiliated neutral party
          having experience with or knowledge in the wireless communications
          equipment industry to be chosen within twenty (20) days after written
          notice by either party demanding mediation(the costs therefor to be
          shared equally); and (iii) if within sixty (60) days of the initial
          demand for mediation by one of the parties, the dispute cannot be
          resolved by mediation, then the dispute shall be submitted by the

18.  GENERAL PROVISIONS


     a.   All information, data and materials provided by either party under
          this Agreement or prior to the Effective Date of this Agreement shall
          be subject to the terms and conditions of the Non-Disclosure Agreement
          to be executed by the parties concurrently with this Agreement and
          attached hereto as Exhibit E.

     b.   Seller and Customer may issue a joint press release concerning the
          execution of this Agreement. Such press release shall be subject to
          prior review and written approval by both parties, not to be
          unreasonably withheld.

     c.   Waiver by either party of any obligation or default by the other party
          shall not be deemed a waiver by such party of any other obligation or
          default.

     d.   Any rights of cancellation, termination or other remedies prescribed
          in this Agreement are cumulative and are not intended to be exclusive
          of any other remedies to which the injured party may be entitled at
          law or equity (including but not limited to the remedies of specific
          performance and cover) in case of any breach or threatened breach by
          the other party of any provision of this Agreement, unless such other
          remedies which are not prescribed in this Agreement are specifically
          limited or excluded by this Agreement. The use of one or more
          available remedies shall not bar the use of any other remedy for the
          purpose of enforcing the provisions of this Agreement; provided,
          however, that a party shall not be entitled to retain the benefit of
          inconsistent remedies.

     e.   If any of the provisions of this Agreement shall be invalid or
          unenforceable, such invalidity or unenforceability shall not
          invalidate or render unenforceable the entire Agreement, but rather
          the entire Agreement shall be construed as if not containing the
          particular invalid or unenforceable provisions, and the rights and
          obligations or Seller and Customer shall be construed and enforced
          accordingly.

     f.   This Agreement, including all Exhibits attached to or referenced in
          this Agreement, shall constitute the entire agreement between Customer
          and Seller with respect to the subject matter hereof and supersedes
          all prior discussions, agreements and representations, whether oral or
          written.

     g.   No provision of this Agreement shall be deemed waived, amended or
          modified by any party hereto, unless such waiver, amendment or
          modification is in writing and signed by a duly authorized
          representative of each of the parties.

     h.   Each party shall comply with all applicable U.S. and foreign export
          control laws and regulations and shall not export or re-export any
          technical data or Products or Services except in compliance with the
          applicable export control laws and regulations of the U.S. and any
          foreign country.

     i.   The parties shall not disclose the financial value of this Agreement

          information.

                               SOFTWARE LICENSE

For purposes of uniformity and brevity, references to Agreement or to an Exhibit
shall refer to the Purchase Agreement to which this document is Exhibit D and to
the other Exhibits to that Agreement.  All definitions set forth in the
Agreement shall apply hereto.

1.   Scope

     Pursuant to the above-identified Agreement, Software will be delivered by
     Seller to Customer for use with the Products according to the terms of the
     Agreement and this Exhibit. Customer shall then become a licensee with
     respect to such Software.

<PAGE>
 
2.   Licensing Grant

     2.1  CONCURRENT WITH EXECUTION OF THE AGREEMENT, SELLER GRANTS TO CUSTOMER
          A REVOCABLE, NON-EXCLUSIVE AND NON-TRANSFERABLE LICENSE UNDER SELLER'S
          APPLICABLE PROPRIETARY RIGHTS TO USE SOFTWARE DELIVERED TO CUSTOMER
          HEREUNDER IN ACCORDANCE WITH THE TERMS AND CONDITIONS SET FORTH
          HEREIN.

     2.2  CUSTOMER AGREES TO PAY THE LICENSING FEES FOR THE RIGHT TO USE THE
          SOFTWARE AND FEATURES AND FOR ANY SUPPORT THEREOF AS SET FORTH IN
          EXHIBIT A (PRICING) OR IN AN AMENDMENT THERETO. THE LICENSING FEE IS A
          ONE TIME FEE WHICH GRANTS THE CUSTOMER THE RIGHT TO USE THE VERSION OF
          SOFTWARE LICENSED FOR AS LONG AS THE CUSTOMER OWNS THE PRODUCT.

3.   Limitations On Use Of Software

     3.1  WITHOUT THE PRIOR WRITTEN CONSENT OF SELLER, CUSTOMER SHALL ONLY USE
          THE SOFTWARE IN CONJUNCTION WITH A SINGLE PRODUCT EXISTING WITHIN THE
          SITE SPECIFIED IN THE PO ("DESIGNATED PRODUCT").

     3.2  CUSTOMER MAY USE THE SOFTWARE TO ROUTINELY OPERATE AND MAINTAIN THE
          DESIGNATED PRODUCT. FOR PURPOSES OF THIS SUBSECTION, "MAINTAIN" SHALL
          BE CONSTRUED TO MEAN PERFORMING DIAGNOSTIC TESTING CONSISTENT WITH
          CUSTOMER'S OBLIGATION TO PROVIDE THE FIRST LEVEL OF MAINTENANCE. UNDER
          NO CONDITION SHALL THE SOFTWARE BE USED FOR ANY OTHER PURPOSE,
          INCLUDING, BUT NOT LIMITED TO, SUBSTITUTED PRODUCTS, OR PRODUCTS NOT
          OWNED BY CUSTOMER, OR PRODUCTS LOCATED AT A LOCATION OTHER THAN THE
          SITE SPECIFIED IN THE PO.

     3.3  THE LICENSE GRANTED TO CUSTOMER IN SECTION 2 IS PERSONAL AND MAY NOT
          BE TRANSFERRED TO ANOTHER PRODUCT OR SITE WITHOUT THE WRITTEN CONSENT
          OF SELLER.

     3.4  TO THE EXTENT SPECIFIED IN EXHIBIT A OR AN AMENDMENT THERETO AND
          PROVIDED CUSTOMER HAS PAID ANY APPLICABLE LICENSING FEES, CUSTOMER
          SHALL HAVE THE RIGHT TO USE FEATURES IN ACCORDANCE WITH THE TERMS OF
          THIS EXHIBIT. CUSTOMER ACKNOWLEDGES THAT THE SOFTWARE MAY CONTAIN
          THEREIN SEVERAL ADDITIONAL FEATURES WHICH ARE EACH COVERED BY SEPARATE
          LICENSING FEES. CUSTOMER AGREES NOT TO USE, AND THE LICENSE
          SPECIFICALLY DOES NOT EXTEND TO, SUCH ADDITIONAL FEATURES UNLESS THEY
          ARE SPECIFIED IN EXHIBIT A OR AN AMENDMENT THERETO AND PROVIDED
          CUSTOMER HAS PAID THE APPLICABLE LICENSING FEES FOR SUCH ADDITIONAL
          FEATURES.

     3.5  THE SOFTWARE IS SUBJECT TO LAWS PROTECTING TRADE SECRETS, KNOW-HOW,
          CONFIDENTIALITY AND COPYRIGHT.

<PAGE>
 
     3.6  CUSTOMER SHALL NOT TRANSLATE, MODIFY, ADAPT, DECOMPILE, DISASSEMBLE,
          OR REVERSE ENGINEER THE SOFTWARE OR ANY PORTION THEREOF.

     3.7  UNLESS OTHERWISE EXPRESSLY AGREED BY SELLER, CUSTOMER SHALL NOT PERMIT
          ITS DIRECTORS, OFFICERS, EMPLOYEES OR ANY OTHER PERSON UNDER ITS
          DIRECT OR INDIRECT CONTROL, TO WRITE, DEVELOP, PRODUCE, SELL, OR
          LICENSE ANY SOFTWARE THAT PERFORMS THE SAME FUNCTIONS AS THE SOFTWARE
          BY MEANS DIRECTLY ATTRIBUTABLE TO ACCESS TO THE SOFTWARE (E.G. REVERSE
          ENGINEERING OR COPYING).

     3.8  CUSTOMER SHALL NOT EXPORT THE SOFTWARE FROM THE UNITED STATES WITHOUT
          THE WRITTEN PERMISSION OF SELLER. IF WRITTEN PERMISSION IS GRANTED FOR
          EXPORT OF THE SOFTWARE, THEN CUSTOMER SHALL COMPLY WITH ALL U.S. LAWS
          AND REGULATIONS FOR SUCH EXPORTS AND SHALL HOLD SELLER HARMLESS,
          INCLUDING LEGAL FEES AND EXPENSES FOR ANY VIOLATION OR ATTEMPTED
          VIOLATION OF THE U.S. EXPORT LAWS.

4.   Right To Copy, Protection And Security

     4.1  SOFTWARE PROVIDED HEREUNDER MAY BE COPIED (FOR BACK-UP PURPOSES ONLY)
          IN WHOLE OR IN PART, IN PRINTED OR MACHINE-READABLE FORM FOR
          CUSTOMER'S INTERNAL USE ONLY, PROVIDED, HOWEVER, THAT NO MORE THAN TWO
          (2) PRINTED COPIES AND TWO (2) MACHINE-READABLE COPIES SHALL BE IN
          EXISTENCE AT ANY ONE TIME WITHOUT THE PRIOR WRITTEN CONSENT OF SELLER,
          OTHER THAN COPIES RESIDENT IN THE PRODUCTS.

     4.2  WITH REFERENCE TO ANY COPYRIGHT NOTICE OF SELLER ASSOCIATED WITH
          SOFTWARE, CUSTOMER AGREES TO INCLUDE THE SAME ON ALL COPIES IT MAKES
          IN WHOLE OR IN PART. SELLER'S COPYRIGHT NOTICE MAY APPEAR IN ANY OF
          SEVERAL FORMS, INCLUDING MACHINE-READABLE FORM. USE OF A COPYRIGHT
          NOTICE ON THE SOFTWARE DOES NOT IMPLY THAT SUCH HAS BEEN PUBLISHED OR
          OTHERWISE MADE GENERALLY AVAILABLE TO THE PUBLIC.

     4.3  CUSTOMER AGREES TO KEEP CONFIDENTIAL, IN ACCORDANCE WITH THE TERMS OF
          THE AGREEMENT, AND NOT PROVIDE OR OTHERWISE MAKE AVAILABLE IN ANY FORM
          ANY SOFTWARE OR ITS CONTENTS, OR ANY PORTION THEREOF, OR ANY
          DOCUMENTATION PERTAINING TO THE SOFTWARE, TO ANY PERSON OTHER THAN
          EMPLOYEES OF CUSTOMER OR SELLER.

     4.4  SOFTWARE, INCLUDING FEATURES IS THE SOLE AND EXCLUSIVE PROPERTY OF
          SELLER AND NO TITLE OR OWNERSHIP RIGHTS TO THE SOFTWARE OR ANY OF ITS
          PARTS, INCLUDING DOCUMENTATION, IS TRANSFERRED TO CUSTOMER.

     4.5  CUSTOMER ACKNOWLEDGES THAT IT IS THE RESPONSIBILITY OF CUSTOMER TO
          TAKE ALL REASONABLE MEASURES TO SAFEGUARD SOFTWARE AND TO PREVENT ITS
          UNAUTHORIZED USE OR DUPLICATION.

5.   Remedies

     Customer acknowledges that violation of the terms of this Exhibit or the
     Agreement shall cause Seller irreparable harm for which monetary damages
     may be inadequate, and Customer agrees that Seller may seek temporary or
     permanent injunctive relief without the need to prove actual harm in order
     to protect Seller's interests.

6.   Term

     Unless otherwise terminated pursuant to Section 7 herein, the term of the
     license granted pursuant to Section 2 herein shall be co-extensive with the
     term of any licensing and/or maintenance fees paid by Customer to Seller
     pursuant to Exhibit A or an Amendment thereto.

7.   Termination

     7.1  THE LICENSE GRANTED HEREUNDER MAY BE TERMINATED BY CUSTOMER UPON ONE
          (1) MONTH'S PRIOR WRITTEN NOTICE.

     7.2  SELLER MAY TERMINATE THE LICENSE GRANTED HEREUNDER IF CUSTOMER IS IN
          DEFAULT OF ANY OF THE TERMS AND CONDITIONS OF THE AGREEMENT OR
          EXHIBITS, AND SUCH TERMINATION SHALL BE EFFECTIVE IF CUSTOMER FAILS TO
          CORRECT SUCH DEFAULT WITHIN TEN (10) DAYS AFTER WRITTEN NOTICE THEREOF
          BY SELLER. THE PROVISIONS OF SECTIONS 4 AND 5 HEREIN SHALL SURVIVE
          TERMINATION OF ANY SUCH LICENSE.

     7.3  WITHIN ONE (1) MONTH AFTER TERMINATION OF THE LICENSE GRANTED
          HEREUNDER, CUSTOMER SHALL FURNISH TO SELLER A DOCUMENT CERTIFYING THAT
          THROUGH ITS BEST EFFORTS AND TO THE BEST OF ITS KNOWLEDGE, THE
          ORIGINAL AND ALL COPIES IN WHOLE OR IN PART OF ALL SOFTWARE, IN ANY
          FORM, INCLUDING ANY COPY IN AN UPDATED WORK, HAVE BEEN RETURNED TO
          SELLER OR DESTROYED. WITH PRIOR WRITTEN CONSENT FROM SELLER, CUSTOMER
          MAY RETAIN ONE (1) COPY FOR ARCHIVAL PURPOSES ONLY.

8.   Rights Of The Parties

     8.1  NOTHING CONTAINED HEREIN SHALL BE DEEMED TO GRANT, EITHER DIRECTLY OR
          BY IMPLICATION, ESTOPPEL, OR OTHERWISE, ANY LICENSE UNDER ANY PATENTS
          OR PATENT APPLICATIONS OF SELLER; EXCEPT THAT CUSTOMER SHALL HAVE A
          NON-EXCLUSIVE, LICENSE UNDER SELLER'S PATENTS AND PATENT APPLICATIONS
          TO USE, IN SELLER-SUPPLIED
<PAGE>
 
     8.2  EQUIPMENT ONLY, SOFTWARE SUPPLIED HEREUNDER, WHEN SUCH LICENSE IS
          IMPLIED OR OTHERWISE ARISES BY OPERATION OF LAW BY VIRTUE OF THE
          PURCHASE OF SUCH COPIES FROM SELLER.

     8.3  RIGHTS IN PROGRAMS OR OPERATING SYSTEMS OF THIRD PARTIES, IF ANY, ARE
          FURTHER LIMITED BY THEIR LICENSE AGREEMENTS WITH SUCH THIRD PARTIES,
          WHICH AGREEMENTS ARE HEREBY INCORPORATED BY REFERENCE THERETO AND MADE
          A PART HEREOF AS IF FULLY SET FORTH HEREIN. CUSTOMER AGREES TO ABIDE
          THEREBY.

     8.4  DURING THE TERM OF THE LICENSE GRANTED PURSUANT TO SECTION 2 HEREIN
          AND FOR A PERIOD OF ONE (1) YEAR AFTER EXPIRATION OR TERMINATION,
          SELLER, AND WHERE APPLICABLE, ITS LICENSOR(S), OR THEIR
          REPRESENTATIVES MAY, UPON PRIOR NOTICE TO CUSTOMER, A) INSPECT THE
          FILES, COMPUTER PROCESSORS, EQUIPMENT, FACILITIES AND PREMISES OF
          CUSTOMER DURING NORMAL WORKING HOURS TO VERIFY CUSTOMER'S COMPLIANCE
          WITH THIS AGREEMENT, AND B) WHILE CONDUCTING SUCH INSPECTION, COPY OR
          RETAIN ALL SOFTWARE, INCLUDING THE MEDIUM ON WHICH IT IS STORED AND
          ALL DOCUMENTATION THAT CUSTOMER MAY POSSESS IN VIOLATION OF THE
          LICENSE OR THE AGREEMENT.

     8.5  CUSTOMER ACKNOWLEDGES THAT THE PROVISIONS OF THIS EXHIBIT D ARE
          INTENDED TO INURE TO THE BENEFIT OF SELLER AND ITS LICENSORS AND THEIR
          RESPECTIVE SUCCESSORS IN INTEREST. CUSTOMER ACKNOWLEDGES THAT SELLER
          OR ITS LICENSORS HAVE THE RIGHT TO ENFORCE THESE PROVISIONS AGAINST
          CUSTOMER, WHETHER IN SELLER'S OR ITS LICESNSOR'S NAME.

     warranty that the Software will perform without error. Customer agrees that
     it is Customer's responsibility to select and test the Software to be sure

     copy such Confidential Information, each such copy shall contain and state

          provide such services; (iv) unauthorized alterations or repairs have
          been made to the Product, or parts have been used in the Product which

8.   INFRINGEMENT INDEMNITY

     a.   Seller shall indemnify and hold harmless Customer and its Affiliates
          against any and all liabilities, losses, costs, damages and expenses,
          including reasonable attorney's fees, associated with any claim or
          action for actual or alleged infringement by any Product or Software
          supplied in accordance with this Agreement of any United States
          patent, trademark, copyright, trade secret or other intellectual
          property right incurred by Customer and its Affiliates as a result of
          Customer's use of such Products or Software in accordance with this
          Agreement provided that (i) Customer promptly notifies Seller in
          writing of the claim, (ii) Customer gives Seller full opportunity and
          authority to assume sole control of the defense and all related
          settlement negotiations, and (iii) Customer gives Seller information
          and assistance for the defense (Customer will be reimbursed for
          reasonable costs and expenses incurred in rendering such assistance,
          against receipt of invoices therefor). Subject to the conditions and
          limitations of liability stated in this Agreement, Seller shall
          indemnify and hold harmless Customer from all payments, which by final
          judgments in such claims, may be assessed against Customer on account
          of such alleged infringement and shall pay resulting settlements,
          costs and damages finally awarded against Customer by a court of law,
          arbitration or other adjudication of the claim.

     b.   Customer agrees that if the Products or Software become, or in
          Seller's opinion are likely to become, the subject of such a claim,
          Customer will permit Seller, at its option and expense, either to
          procure the right for Customer to continue using such Products or
          Software or to replace or modify same so that they become non-
          infringing as long as they continue to conform in all material
          respects to the specifications contained in this Agreement and
          Exhibits, and, if neither of the foregoing alternatives is available
          on terms which are acceptable to Seller, Customer shall at the written
          request of Seller, return the infringing or potentially infringing
          Products or Software and all the rights thereto at Seller's expense.
          Customer shall receive a refund of the prorated undepreciated portion
          of the Purchase Price actually paid by Customer to Seller for the
          returned portion of the Products. The Purchase Price shall be
          depreciated over a five (5) year period.
 
     c.   Seller shall have no obligation to Customer with respect to any claim
          of patent or copyright infringement which is based upon (i) adherence
          to specifications, designs or instructions furnished by Customer, (ii)
          the combination, operation or use of any Products supplied hereunder
          with products, software or data not supplied by Seller, (iii) the
          alteration of the Products or modification of any 
<PAGE>
 
          Software made by any party other than Seller; or (iv) the Customer's
          use of a superseded or altered release of some or all of the Software
          if infringement would have been avoided by the use of a subsequent
          unaltered release of the Software that is provided to the Customer.

9.   INDEPENDENT CONTRACTOR

Seller hereby declares and agrees that Seller is engaged in an independent
business and will perform its obligations under this Agreement as an independent
contractor and not as the agent or employee of Customer and has no authority to
represent Customer as to any matters.   Seller shall be solely responsible for
payment of compensation to its personnel and for injury to them in the course of
their employment except to the extent that any intentional or negligent act of
Customer is solely and directly responsible for any such injury .  Seller is
responsible for payment of all federal, state, or local taxes or contributions
imposed or required under unemployment insurance, social security and income tax
laws for persons employed by Seller to perform Seller's obligations under this
Agreement.

10.  INDEMNIFICATION

Seller shall indemnify Customer, its employees and directors, and each of them,
against any loss, damage, claim,  or liability, arising out of, as a result of,
or in connection with the use of the Product in accordance with this Agreement
or the acts or omissions, negligent or otherwise, of Seller in the performance
of this Agreement, or a contractor or an agent of Seller or an employee of
anyone of them, except where such loss, damage, claim, or liability arises from
the sole negligence or willful misconduct of Customer, agents or its employees.
Seller shall, at its own expense, defend any suit asserting a claim for any
loss, damage or liability specified above, and Seller shall pay any costs,
expenses  and attorneys' fees that may be incurred by Customer in connection
with any such claim or suit or in enforcing the indemnity granted above,
provided that Seller (i) is given prompt notice of any such claim or suit and
(ii) full opportunity to assume control of the defense or settlement.  Neither
Seller nor Customer shall not be liable to the other for indirect or
consequential damages, including but not limited to lost profits.

11.  TERM AND TERMINATION

The term of this Agreement shall be [***] from the Effective Date.  If either
party is in material default of any of its obligations under this Agreement and
such default continues for thirty (30) days after written notice thereof by the
party not in default, the nondefaulting party may cancel this Agreement.   In
addition, a party may cancel this Agreement if a petition in bankruptcy or under
any insolvency law is filed by or against the other party and is not dismissed
within sixty (60) days of the commencement thereof.
 
12.  ASSIGNMENT

          foregoing, without the prior written consent of Seller, (i) the
          Software license granted to Customer in the form of Exhibit D
          (Software License), may not be sublicensed, assigned or otherwise
          transferred by Customer except to Affiliates; (ii) the Products may
          not be transported, relocated, sold or otherwise transferred outside
          the United States and (iii) no assignment may be made to an entity
          which Seller considers to be a competitor.

     c.   Subject to the provisions of paragraphs a, and b above, this Agreement

15.  COMPLIANCE WITH LAWS

Seller shall comply with all applicable federal, state and local laws,
regulations and codes, including the procurement of permits and licenses when
needed, in the performance of this Agreement.

16.  FORCE MAJEURE

Except for payment of moneys due, neither party shall be liable for delays in
delivery or performance or for failure to manufacture, deliver or perform
resulting from acts beyond the reasonable control of the party responsible for
performance.  Such acts shall include, but not be limited to (a) acts of God,
acts of a public enemy, acts or failures to act by the other party, acts of
civil or military authority, governmental priorities, strikes or other labor
disturbances, hurricanes, earthquakes, fires, floods, epidemics, embargoes, war,
riots, and loss or damage to goods in transit; or (b) inability to obtain
necessary products, components, services or facilities on account of causes
beyond the reasonable control of the delayed party or its suppliers.  In the
event of any such delay, the date(s) of delivery or performance shall be
extended for as many days are reasonably required due to the delay.  If such
delay continues for 45 days, either party may terminate the Purchase Order
affected by the event by providing written notice.
 
17.  GOVERNING LAW; DISPUTE RESOLUTION

     a.   This Agreement and each Purchase Order shall be construed in
          accordance with the internal laws of the State of Washington, without
          regard to its choice of law provisions.

     b.   Any and all disputes arising between the parties shall be resolved in
          the following order: (i) by good faith negotiation between
          representatives of Customer and Seller who have authority to fully and
          finally resolve the dispute to commence within ten (10) days of the
          request of either party; (ii) in the event that the parties have not
          succeeded in negotiating a resolution of the dispute within ten (10)
          days after the first meeting, then the dispute will be resolved by
          nonbinding mediation to be held in a mutually agreed location in the
          United States, using a mutually agreed upon non-affiliated neutral
          party having experience with or knowledge in the wireless
          communications equipment industry to be chosen within twenty (20) days
          after written notice by either party demanding mediation (the costs
          therefor to be shared equally); and (iii) if within sixty (60) days of
          the initial demand for mediation by the parties, the dispute cannot be
          resolved by mediation, then a party may institute litigation in a
          court having subject matter jurisdiction, and the parties expressly
          consent and submit themselves to the personal jurisdiction of such
          court.

18.  DELAY PENALTIES

     a.   The parties agree that damages for delay are difficult to calculate
          accurately, and, therefore, agree that penalties will be paid for late
          performance of certain of Seller's obligations under this Agreement.

     a.   All information, data and materials provided by either party under
          this Agreement shall be subject to the terms and conditions of the 
          Non-Disclosure Agreement between the parties dated April 10, 1996.

     b.   Seller and Customer may issue a joint press release concerning the

          unreasonably withheld.

     c.   Waiver by either party of any obligation or default by the other party
          shall not be deemed a waiver by such party of any other obligation or
          default.

     d.   Any rights of cancellation, termination or other remedies prescribed
          in this Agreement are cumulative and are not intended to be exclusive
          of any other remedies to which the injured party may be entitled at
          law or equity (including but not limited to the remedies of specific
          performance and cover) in case of any breach or threatened breach by
          the other party of any provision of this Agreement, unless such other
          remedies which are not prescribed in this Agreement are specifically
          limited or excluded by this Agreement.  The use of one or more
          available remedies shall not bar the use of any other remedy for the
          purpose of enforcing the provisions of this Agreement; provided,
          however, that a party shall not be entitled to retain the benefit of
          inconsistent remedies.

     e.   If any of the provisions of this Agreement shall be invalid or
          unenforceable, such invalidity or unenforceability shall not
          invalidate or render unenforceable the entire Agreement, but rather
          the entire Agreement shall be construed as if not containing the
          particular invalid or unenforceable provisions, and the rights and
          obligations of Seller and Customer shall be construed and enforced
          accordingly.

     f.   This Agreement, including all Exhibits attached to or referenced in
          this Agreement, shall constitute the entire agreement between Customer
          and Seller with respect to the subject matter hereof.

     g.   No provision of this Agreement shall be deemed waived, amended or
          modified by any party hereto, unless such waiver, amendment or
          modification is in writing and signed by a duly authorized
          representative of each of the parties.

     h.   This Agreement applies only to sales of Products and Services in the
          United States.

     i.   Each party shall comply with all applicable U.S. and foreign export
          control laws and regulations and shall not export or re-export any
          technical data or products except in compliance with the applicable
          export control laws and regulations of the U.S. and any foreign
          country.

         Spotlight Units, or Spotlight Units not owned by Customer, or Spotlight
         Units located at a location other than the site specified in the
         Purchase Order.

   4.3   The License granted to Customer in Section 2 is personal and may not be
         transferred to another Spotlight or site or another entity without the
         written consent of Seller.
 
   4.4   The Software is subject to laws protecting patents, trade secrets, 
         know-how, confidentiality and copyright.

         reverse engineer the Software or any portion thereof.

   4.6   Unless otherwise expressly agreed by Seller, Customer shall not permit
         its directors, officers, employees or any other person under its direct
         or indirect control, to write, develop, produce, sell, or license any
         software that performs the same functions as the Software by means
         directly attributable to access to the Software (e.g. reverse
         engineering or copying).

   4.7   Customer shall not export the Software from the United States without
         the written permission of Seller.  If written permission is granted for
         export of the Software, then Customer shall comply with all U.S. laws
         and regulations for such exports and shall hold Seller harmless,
         including legal fees and expenses for any violation or attempted
         violation of the U.S. export laws.

   4.8   Customer acknowledges that Seller owns the Software and that any rights
         therein not specifically granted in this License are the exclusive
         property of Seller.

5. RIGHT TO COPY, PROTECTION AND SECURITY

   5.1   Software provided hereunder may be copied (for back-up purposes only)
         in whole or in part, in printed or machine-readable form for Customer's
         internal use only, provided, however, that no more than two (2) printed
         copies and two (2) machine-readable copies shall be in existence at any
         one time without the prior written consent of Seller, other than copies
         electronically resident in the Spotlights.

   5.2   With reference to any copyright notice of Seller associated with
         Software, Customer agrees to include the same on all copies it makes in
         whole or in part.  Seller's copyright notice may appear in any of
         several forms, including machine-readable form.  Use of a copyright

   Agreement shall cause Seller irreparable harm for which monetary damages may
   be inadequate, and Customer agrees that Seller may, in addition to any other
   legal or equitable remedy it may have, seek temporary or permanent injunctive
   relief without the need to prove actual harm in order to protect Seller's
   interests.

7. TERM

   Unless otherwise terminated pursuant to Section 8 hereof, or in the event
   that Customer is required to return the Software pursuant to section 8(b) of
   the Purchase Agreement, the term of the license granted pursuant to Section 2
   herein shall be perpetual.

          material default of any of the terms and conditions of this Exhibit D
          (Software License Agreement) , and such termination shall be effective
          if Customer fails to correct such default within thirty (30) days
          after written notice thereof by Seller. The provisions of Sections 4
          and 5 herein shall survive termination of any such license.

   8.3    Within one (1) month after termination of the license granted
          hereunder, Customer shall furnish to Seller a document certifying that
          through its best efforts and to the best of its knowledge, the
          original and all copies in whole or in part of all Software, in any
          form, including any copy in an updated work, have been returned to
          Seller or destroyed. With prior written consent from Seller, Customer
          may retain one (1) copy for archival purposes only.

9. RIGHTS OF THE PARTIES

   9.1    Nothing contained herein shall be deemed to grant, either directly or
          by implication, estoppel, or otherwise, any license under any patents,
          patent applications or copyrights of Seller except as expressly
          granted herein.

   9.2    Rights in programs or operating systems of third parties, if any, are

          and for a period of one (1) year after expiration or termination,
          Seller, and where applicable, its licensor(s), or their
          representatives may, upon prior notice to Customer, a) inspect the
          files, computer processors, equipment, facilities and premises of
          Customer during normal working hours to verify Customer's compliance
          with this Agreement, and b) while conducting such inspection, copy
          and/or retain all Software, including the medium on which it is stored
          and all documentation that Customer may possess in violation of the
          license or the Agreement.

   9.4    Customer acknowledges that the provisions of this Exhibit E are
          intended to inure to the benefit of Seller and its licensors and their
          respective successors in interest. Customer acknowledges that Seller
          or its licensors have the right to enforce these provisions against
          Customer, whether in Seller's or its licensor's name.

                 AS ARRANGEMENTS WITH THE MANUFACTURERS OR VENDORS THEREOF
                 PERMIT.

          of Products, total amounts for each item, shipping charges, other
          charges, applicable sales or use taxes and total amount due. For
          invoices rendered pursuant to subsection (b) hereof, Section 4(c) and
          Exhibit E (Product Maintenance Program), Customer shall promptly pay
          Seller by wire transfer (to Seller's bank account designated in
          subsection (g) hereof) in U.S. Dollars the amount due within forty-

     e.   If Customer disputes any invoices rendered or amount paid, Customer
          will so notify Seller, and the parties will use their reasonable
          efforts to resolve such dispute expeditiously. Provided that Customer
          so notifies Seller of a disputed invoice and there is a good faith
          basis for such dispute, the time for paying the portion of the invoice
          in dispute shall be extended by a period of time equal to the time
          between Seller's receipt of such notice from Customer and the
          resolution of such dispute.

     f.   If financing to fund Customer's purchase of Products pursuant to this
          Agreement has been arranged, Customer may utilize such financing in
          making payments in accordance with the terms of this Agreement and as
          required under this subsection. The parties agree that the foregoing
          does not constitute an offer by Seller to make available such
          financing, or to arrange such financing for Customer and any such
          financing is subject to agreement of the parties and the negotiation
          and execution of separate documentation.


     g.   Except as otherwise specified in this Agreement, all payments from one
          party to the other shall be made by wire transfer into the following

8.   INFRINGEMENT INDEMNITY

          reimbursed for reasonable costs and expenses incurred in rendering
          such assistance, against receipt of invoices therefor). Subject to the
          conditions and limitations of liability stated in this Agreement,
          Seller shall indemnify and hold harmless Customer from all payments,
          which by final judgments in such suits, may be assessed against

          resulting settlements, costs and damages finally awarded against
          Customer by a court of law.

     b.   Customer agrees that if the Products become, or in Seller's opinion
          are likely to become, the subject of such a claim, Customer will
          permit Seller, at its option and expense, either to procure the right
          for Customer to continue using such Products

          or to replace or modify same so that they become non-infringing, and,
          if neither of the foregoing alternatives is available on terms which
          are acceptable to Seller, Customer shall at the written request of
          Seller, return the infringing or potentially infringing Products.
          Customer shall receive a refund of the prorated undepreciated portion
          of the price actually paid by Customer to Seller for the returned
          portion of the Products. The price shall be depreciated over a seven
          (7) year period.

     c.   Seller shall have no obligation to Customer with respect to any claim
          of patent or copyright infringement which is based upon or related to
          (i) adherence to customized specifications, designs or instructions
          furnished by Customer, (ii) the interconnection or interface of any
          Products supplied hereunder with base station products or software not
          approved by Seller (such products approved by Seller are set forth in
          Exhibit B, Section 2.2.7.), (iii) the alteration of the Products or
          modification of any Software made by any party other than Seller, or
          (iv) the Customer's use of a superseded or altered release of some or
          all of the Software if infringement would have been avoided by the use
          of a subsequently altered release of the Software that is provided to
          Customer.

business and will perform its obligations under this Agreement as an independent

or in part, by the acts or omissions, negligent or otherwise, of Seller or a
contractor or an agent of Seller or an employee of anyone of them, except where

liability specified above, and Seller shall pay any costs and attorneys' fees
that may be incurred by Customer in connection with any such claim or suit or in

Pursuant to the above-identified Agreement, Software will be delivered by Seller
to Customer for use with the Products according to the terms of the Agreement
and this Exhibit.  Customer shall then become a licensee with respect to such
Software.

2.   LICENSING GRANT

     2.1  CONCURRENT WITH EXECUTION OF THE AGREEMENT, SELLER GRANTS TO CUSTOMER
          A REVOCABLE, NON-EXCLUSIVE AND NON-TRANSFERABLE LICENSE UNDER SELLER'S
          APPLICABLE PROPRIETARY RIGHTS TO USE SOFTWARE DELIVERED TO CUSTOMER
          HEREUNDER IN ACCORDANCE WITH THE TERMS AND CONDITIONS SET FORTH
          HEREIN.

     2.2  CUSTOMER AGREES TO PAY THE LICENSING FEES FOR THE RIGHT TO USE THE
          SOFTWARE AND FEATURES AND FOR ANY SUPPORT THEREOF AS SET FORTH IN
          EXHIBIT A (PRICING) OR IN AN AMENDMENT THERETO. THE LICENSING FEE IS A
          ONE TIME FEE WHICH GRANTS THE CUSTOMER THE RIGHT TO USE THE VERSION OF
          SOFTWARE LICENSED FOR AS LONG AS THE CUSTOMER OWNS THE PRODUCT.

3.   LIMITATIONS ON USE OF SOFTWARE

     3.1  WITHOUT THE PRIOR WRITTEN CONSENT OF SELLER, CUSTOMER SHALL ONLY USE

     3.2  CUSTOMER MAY USE THE SOFTWARE TO ROUTINELY OPERATE AND MAINTAIN THE
          DESIGNATED PRODUCT. FOR PURPOSES OF THIS SUBSECTION, "MAINTAIN" SHALL
          BE CONSTRUED TO MEAN PERFORMING DIAGNOSTIC TESTING CONSISTENT WITH
          CUSTOMER'S OBLIGATION TO PROVIDE THE FIRST LEVEL OF MAINTENANCE. UNDER
          NO CONDITION SHALL THE SOFTWARE BE USED FOR ANY OTHER PURPOSE,
          INCLUDING, BUT NOT LIMITED TO, SUBSTITUTED PRODUCTS, OR PRODUCTS NOT
          OWNED BY CUSTOMER, OR PRODUCTS LOCATED AT A LOCATION OTHER THAN THE
          SITE SPECIFIED IN THE PO.

     3.3  THE LICENSE GRANTED TO CUSTOMER IN SECTION 2 IS PERSONAL AND MAY NOT
          BE TRANSFERRED TO ANOTHER PRODUCT OR SITE WITHOUT THE WRITTEN CONSENT
          OF SELLER.

     3.4  TO THE EXTENT SPECIFIED IN EXHIBIT A OR AN AMENDMENT THERETO AND
          PROVIDED CUSTOMER HAS PAID ANY APPLICABLE LICENSING FEES, CUSTOMER
          SHALL HAVE THE RIGHT TO USE FEATURES IN ACCORDANCE WITH THE TERMS OF
          THIS EXHIBIT. CUSTOMER ACKNOWLEDGES THAT THE SOFTWARE MAY CONTAIN
          THEREIN SEVERAL ADDITIONAL FEATURES WHICH ARE EACH COVERED BY SEPARATE
          LICENSING FEES. CUSTOMER AGREES NOT TO USE, AND THE LICENSE
          SPECIFICALLY DOES NOT EXTEND TO, SUCH ADDITIONAL FEATURES UNLESS THEY
          ARE SPECIFIED IN EXHIBIT A OR AN AMENDMENT THERETO AND PROVIDED
          CUSTOMER HAS PAID THE APPLICABLE LICENSING FEES FOR SUCH ADDITIONAL
          FEATURES.

     3.5  THE SOFTWARE IS SUBJECT TO LAWS PROTECTING TRADE SECRETS, KNOW-HOW,
          CONFIDENTIALITY AND COPYRIGHT.

          OR REVERSE ENGINEER THE SOFTWARE OR ANY PORTION THEREOF.

     3.7  UNLESS OTHERWISE EXPRESSLY AGREED BY SELLER, CUSTOMER SHALL NOT PERMIT
          ITS DIRECTORS, OFFICERS, EMPLOYEES OR ANY OTHER PERSON UNDER ITS
          DIRECT OR INDIRECT CONTROL, TO WRITE, DEVELOP, PRODUCE, SELL, OR
          LICENSE ANY SOFTWARE THAT PERFORMS THE SAME FUNCTIONS AS THE SOFTWARE
          BY MEANS DIRECTLY ATTRIBUTABLE TO ACCESS TO THE SOFTWARE (E.G. REVERSE
          ENGINEERING OR COPYING).

     3.8  CUSTOMER SHALL NOT EXPORT THE SOFTWARE FROM THE UNITED STATES WITHOUT
          THE WRITTEN PERMISSION OF SELLER. IF WRITTEN PERMISSION IS GRANTED FOR
          EXPORT OF THE SOFTWARE, THEN CUSTOMER SHALL COMPLY WITH ALL U.S. LAWS
          AND REGULATIONS FOR SUCH EXPORTS AND SHALL HOLD SELLER HARMLESS,
          INCLUDING LEGAL FEES AND EXPENSES FOR ANY VIOLATION OR ATTEMPTED
          VIOLATION OF THE U.S. EXPORT LAWS.

4.   RIGHT TO COPY, PROTECTION AND SECURITY

     4.1  SOFTWARE PROVIDED HEREUNDER MAY BE COPIED (FOR BACK-UP PURPOSES ONLY)
          IN WHOLE OR IN PART, IN PRINTED OR MACHINE-READABLE FORM FOR
          CUSTOMER'S INTERNAL USE ONLY, PROVIDED, HOWEVER, THAT NO MORE THAN TWO
          (2) PRINTED COPIES AND TWO (2) MACHINE-READABLE COPIES SHALL BE IN
          EXISTENCE AT ANY ONE TIME WITHOUT THE PRIOR WRITTEN CONSENT OF SELLER,
          OTHER THAN COPIES RESIDENT IN THE PRODUCTS.

     4.2  WITH REFERENCE TO ANY COPYRIGHT NOTICE OF SELLER ASSOCIATED WITH

          SEVERAL FORMS, INCLUDING MACHINE-READABLE FORM. USE OF A COPYRIGHT
          NOTICE ON THE SOFTWARE DOES NOT IMPLY THAT SUCH HAS BEEN PUBLISHED OR
          OTHERWISE MADE GENERALLY AVAILABLE TO THE PUBLIC.

     4.3  CUSTOMER AGREES TO KEEP CONFIDENTIAL, IN ACCORDANCE WITH THE TERMS OF
          THE AGREEMENT, AND NOT PROVIDE OR OTHERWISE MAKE AVAILABLE IN ANY FORM

          EMPLOYEES OF CUSTOMER OR SELLER.

     4.4  SOFTWARE, INCLUDING FEATURES IS THE SOLE AND EXCLUSIVE PROPERTY OF
          SELLER AND NO TITLE OR OWNERSHIP RIGHTS TO THE SOFTWARE OR ANY OF ITS
          PARTS, INCLUDING DOCUMENTATION, IS TRANSFERRED TO CUSTOMER.

          TAKE ALL REASONABLE MEASURES TO SAFEGUARD SOFTWARE AND TO PREVENT ITS
          UNAUTHORIZED USE OR DUPLICATION.

5.   REMEDIES

Customer acknowledges that violation of the terms of this Exhibit or the
Agreement shall cause Seller irreparable harm for which monetary damages may be
inadequate, and Customer agrees that Seller may seek temporary or permanent
injunctive relief without the need to prove actual harm in order to protect
Seller's interests.

          MAY RETAIN ONE (1) COPY FOR ARCHIVAL PURPOSES ONLY.

                                LOAN AGREEMENT

                                        

THIS LOAN AGREEMENT is entered into as of October 14, 1997 (this "Loan
Agreement") between METAWAVE COMMUNICATIONS CORPORATION, a Delaware corporation
(herein called "Borrower"), and IMPERIAL BANK (herein called "Bank").

     1.   COMMITMENT.

          A.   FACILITY-A COMMITMENT.  Subject to all the terms and conditions
of this Loan Agreement and prior to the termination of its commitment as
hereinafter provided, Bank hereby agrees to make loans (each a "Facility-A
Loan") to Borrower, from time to time and in such amounts as Borrower shall
request pursuant to this SECTION 1.A., up to an aggregate principal amount
outstanding under the Facility-A Loan Account (as hereinafter defined) not to
exceed the least of:  (a) Eighty percent (80%) of Eligible Accounts (the
"Borrowing Base") or (b) $5,000,000.00 (the "Facility-A Commitment").  If at any
time or for any reason, the outstanding principal amount of the Facility-A Loan
Account is greater than the least of:  (x) the Borrowing Base or (y) the
Facility-A Commitment, Borrower shall immediately pay to Bank, in cash, the
amount of such excess.  Any commitment of Bank, pursuant to the terms of this
Loan Agreement, to make Facility-A Loans shall expire on the Facility-A Maturity
Date (as hereinafter defined), subject to Bank's right to renew said commitment
in its sole and absolute discretion at Borrower's request.  Any such renewal of
said commitment shall not be binding upon Bank unless it is in writing and
signed by an officer of Bank.  Provided that no Event of Default (as hereinafter
defined) has occurred and is continuing, all or any portion of the Facility-A
Loans advanced by Bank which are repaid by Borrower shall be available for
reborrowing in accordance with the terms hereof.  Borrower promises to pay to
Bank the entire outstanding unpaid principal balance (and all accrued unpaid
interest thereon) of the Facility-A Loan Account on October 14, 1999 ("Facility-
A Maturity Date").

               (1)  FACILITY-A LOANS. The amount of each Facility-A Loan made by
Bank to Borrower hereunder shall be debited to the loan ledger account of
Borrower maintained by Bank for the Facility-A Commitment (herein called the
"Facility-A Loan Account") and Bank shall credit the Facility-A Loan Account
with all loan repayments in respect thereof made by Borrower. When Borrower
desires to obtain a Facility-A Loan, Borrower shall notify Bank (which notice
shall be signed by an officer of Borrower and shall be irrevocable) in
accordance with SECTION 2 hereof, to be received no later than 3:00 p.m. Pacific
time one (1) Banking Day (as hereinafter defined) before the day on which the
Facility-A Loan is to be made. Facility-A Loans may only be used for working
capital purposes and the issuance of letters of credits.

                    (a)  LETTER OF CREDIT USAGE AND SUBLIMIT. Subject to the
availability of the Facility-A Commitment and in reliance on the representations
and warranties of Borrower set forth herein, at any time and from time to time
from the date hereof through the Banking Day immediately prior to the Facility-A
Maturity Date, Bank shall issue for the account of Borrower such standby and
commercial letters of credit ("Letters of Credit") as Borrower may request,
which request shall be made by delivering to Bank a duly executed letter of
credit application on Bank's standard form; provided, however, that the
outstanding and undrawn amounts under all such Letters of Credit (i) shall not
at any time exceed $3,000,000.00 and (ii) shall be deemed to constitute 
Facility-A Loans for the purpose of calculating availability under the 
Facility-A Commitment. Unless Borrower shall have deposited with Bank cash
collateral in an amount sufficient to cover all undrawn amounts under each such
Letter of Credit and Bank shall have agreed in writing, no Letter of Credit
shall have an expiration date that is later than the Facility-A Maturity Date.
All Letters of Credit shall be in form and substance acceptable to Bank in its
sole discretion and shall be subject to the terms and conditions of Bank's
application and letter of credit agreement, in the form of EXHIBIT B attached
hereto and incorporated herein by this reference. Borrower will pay any standard
issuance and other fees that Bank notifies Borrower will be charged for issuing
and processing Letters of Credit for Borrower.

               (2)  LIMITATION ON ADVANCE OF ANY FACILITY-A LOAN.
Notwithstanding any of the provisions contained in SECTION 1.A hereof, prior to
any advance of a Facility-A Loan, a representative of Bank shall have conducted
an audit of Borrower's books and records relating to the Collateral and made
extracts therefrom, and arranged for verification of the Accounts, directly with
the account debtors or otherwise, all with results reasonably satisfactory to
Bank, the cost of such audit of which shall be at Borrower's sole expense. Based
on Bank's review of such audit, and prior to the advance of a 
<PAGE>
 
Facility-A Loan in accordance with the terms of SECTION 1.A hereof, Bank may
adjust the Borrowing Base percentage, in its sole and reasonable discretion, as
provided for under SECTION 9.B. hereof.

               (3)  NON-FORMULA AVAILABILITY. Provided that no Event of Default
has occurred and is continuing, and subject to the availability of the Facility-
A Commitment and in reliance on the representations and warranties of Borrower
set forth herein, at any time from the date hereof through April 30, 1998, Bank
hereby agrees to make Facility-A Loans to Borrower in such amounts as Borrower
shall request pursuant to this SECTION 1.A.(3), in an aggregate principal amount
not to exceed $2,500,000.00 (the "Non-Formula Availability"); provided, however,
that the outstanding amounts under this Non-Formula Availability shall be deemed
to constitute Facility-A Loans for the purpose of calculating availability under
the Facility-A Commitment.

               (4)  INTEREST PAYMENTS ON FACILITY-A LOANS. Borrower further
promises to pay to Bank from the date of the advance of the initial Facility-A
Loan through the Facility-A Maturity Date, on or before the tenth (10th) day of
each month, interest on the average daily unpaid balance of the Facility-A Loan
Account during the immediately preceding month at a rate of interest equal to
the rate of interest per annum which Bank has announced as its prime lending
rate (the "Prime Rate"), which shall vary concurrently with any change in the
Prime Rate. Interest shall be computed at the above rate on the basis of the
actual number of days during which the principal balance of the Facility-A Loan
Account is outstanding divided by 360, which shall for interest computation
purposes be considered one (1) year.

     2.   LOAN REQUESTS.  Requests for Loans hereunder shall be in writing duly
executed by Borrower in the form of EXHIBIT C attached hereto and incorporated
herein by this reference and shall contain a certification setting forth the
matters referred to in SECTION 1, which shall disclose that Borrower is entitled
to the amount and type of Loan being requested.  Bank is hereby authorized to
charge Borrower's deposit account with Bank for all principal and interest due
Bank under this Loan Agreement.

     3.   DELIVERY OF PAYMENTS.  Payment to Bank of all amounts due hereunder
shall be made at its Santa Clara Valley Regional office, or at such other place
as may be designated in writing by Bank from time to time.  If any payment date
fall on a day that is not a day that Bank is open for the transaction of
business ("Banking Day"), the payment due date shall be extended to the next
Banking Day.

     4.   LATE CHARGE.  If any interest payment, principal payment or principal
balance payment required hereunder is not received by Bank on or before ten (10)
days from the date in which such payment becomes due, Borrower shall pay to
Bank, a late charge equal to the lesser of (a) five percent (5.0%) of the amount
of such unpaid payment, in addition to said unpaid payment or (b) the maximum
amount permitted to be charged by applicable law, until remitted to Bank;
provided; however, nothing contained in this SECTION 4, shall be construed as
any obligation on the part of Bank to accept payment of any past due payment or
less than the total unpaid principal balance of the Facility-A Loan Account
following the FacilityA Maturity Date.  All payments shall be applied first to
any late charges due hereunder, next to accrued interest then payable and the
remainder, if any, to reduce any unpaid principal due under the Facility-A Loan
Account.

     5.   DEFAULT INTEREST.  From and after the Facility-A Maturity Date, or
such earlier date as all sums owing under the Facility-A Loan Account becomes
due and payable by acceleration or otherwise, or upon the occurrence of an Event
of Default, at the option of Bank all sums owing under the Facility-A Loan
Account shall bear interest until paid in full at a rate equal to the lesser of
(a) five percent (5.0%) per annum in excess of the then applicable interest rate
provided for in SECTION 1.A.(3) hereof or (b) the maximum amount permitted to be
charged by applicable law, until all obligations hereunder are repaid in full or
the Event of Default is waived or cured to the satisfaction of Bank, as
applicable.

     6.   DEFINITIONS.  As used in this Loan Agreement and unless otherwise

or more remedies hereunder successively or concurrently, and any such action
shall not estop or prevent Bank from pursuing any further remedy which it may

objections raised to such discovery or unavailability of a witness due to
absence or illness. No party shall be entitled to "priority" in conducting

costs of the court reporter at the trial shall be borne equally by the parties.

               (3)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted,  is also to be a reference proceeding
under this provision.

               (4)  In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration. The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, (S) 1280 through (S) 1294.2
of the CCP as amended from time to time. The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration

                                   AMENDMENT
                                      TO
                                LOAN  AGREEMENT

     This Amendment to Loan Agreement (the "Amendment") is entered into as of
May 6, 1998, by and between Imperial Bank ("Bank") and Metawave Communications
Corporation ("Borrower").

                                   RECITALS

     Borrower and Bank are parties to that certain Loan Agreement dated as of
October 14, 1997, as amended from time to time (the "Agreement").  The parties
desire to amend the Agreement in accordance with the terms of this Amendment.

     NOW, THEREFORE, the parties agree as follows:

     1.   The reference in Section 1.A of the Agreement to "$5,000,000" is
amended to read "$7,500,000". The reference in Section 1.A(3) of the Agreement
to "April 30, 1998" is amended to read "June 30, 1998".

     2.   The reference in Section 10.C of the Agreement to "1.00:1.00" is
amended to read "1.50 to 1.00", and Section 10.I is added to the Agreement, as
follows: Upon the date (the "Step-Up Date") that is the earlier to occur of
December 31, 1998 or the date that Borrower receives not less than $40,000,000
from the sale of its equity securities pursuant to an offering made under a
registration statement filed in accordance with the Securities Act of 1933, as
amended, Borrower shall maintain, at all times, (i) a Minimum Tangible Net Worth
of at least $25,000,000 and (ii) a Minimum Quick Ratio of not less than 1.00 to
1.00. Bank waives Borrower's obligation to comply with Section 10.A and Section
10.B until the Step-Up-Date. The definition of Minimum Quick Ratio in Section
10.C is amended to exclude from current liabilities the obligations under the
Notes issued pursuant to the Note Agreement dated as of April 29, 1998 (the
"Note Agreement"). The reference in Sections 10(F) and 10(F) to "twenty five
(25) days" are amended to read "thirty (30) days".

     3.   Notwithstanding the provisions of Clause (8) of the defined term
"Eligible Accounts", the concentration limit for Accounts owing to Borrower by
Alltel, 360 Communications, Millicom, GTE and Airtouch shall be fifty percent
(50%). Bank acknowledges that the terms "Permitted Indebtedness" and "Permitted
Liens" include the indebtedness incurred under, and the security interests
granted in connection with, the Note Agreement and the equipment lease between
Borrower and Insight Investment Corp. The priority of Bank's security interest
in the Collateral is subject to that certain Intercreditor Agreement (the
"Intercreditor Agreement") dated as of April 28, 1998 among Bank and the
Creditors named therein. The IP Security Agreement shall terminate, all
references in the Agreement to the IP Security Agreement shall be deleted, and
Bank shall return the original of the IP Security Agreement to Borrower;
provided that Bank retains a second priority security interest in the Creditor
Collateral, as defined in the Intercreditor Agreement. Borrower and Bank shall
execute an Amendment to Financing Statement in a mutually acceptable form to
clarify that Bank has a first priority security interest in the Imperial
Collateral and a second priority security interest in the Creditor Collateral.
"Collateral" under the General Security Agreement dated as of October 14, 1997
between Borrower and Bank, shall include all of such Imperial Collateral and
Creditor Collateral, subject to the priorities specified in the Intercreditor
Agreement.

     4.   Unless otherwise defined, all capitalized terms in this Amendment
shall be defined in the Agreement. Except as amended, the Agreement remains in
full force and effect.

     5.   Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment (except that the financial statements to which such
Representations and Warranties relate shall be those dated as of March 31, 1998,
not September 30, 1997, and except such representations and warranties to be
expressly true as of a specific date), and that no unwaived or uncured Event of
Default has occurred and is continuing.
<PAGE>
 
     6.   As a condition to the effectiveness of this Amendment, Borrower shall
pay Bank a fee equal to $9,375, plus the expenses incurred by Bank in preparing
this Amendment. This Amendment may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one instrument.

     IN WITNESS WHEREOF, the undersigned have executed this Amendment as of the
first date above written.

                                                      Dated as of April 27, 1998

To the Purchasers named in Schedule I attached hereto that are signatories to
this Agreement

Ladies and Gentlemen:

     The undersigned, Metawave Communications Corporation, a Delaware
corporation (the "Company") agrees with each Purchaser as follows:

SECTION 1. DESCRIPTION OF NOTES; COMMITMENT; WARRANTS.

     Section 1.1.   Description of Notes.  The Company will authorize the issue
and sale of $29,000,000 aggregate original principal amount of its 13.75% Senior
Secured Bridge Notes due April 28, 2000 (the "Notes") to be dated the date of
issue.  Interest on the Notes will accrue at the lower of (i) 13.75% per annum
(as adjusted pursuant to the next succeeding sentence, the "Base Interest Rate")
and (ii) the highest rate permitted by law (such lower amount being referred to
as the "Interest Rate"), and will be payable semi-annually on April 28th and
October 28th of each year, commencing on October 28, 1998, and at maturity.  On
the twelve-month anniversary of the Closing Date, and at the end of each
subsequent one hundred eighty (180) day period, the Base Interest Rate will
increase by 200 basis points, up to a maximum Base Interest Rate of 18.0%.  The
interest shall be payable at the option of the Company (x) in kind by the
issuance to the holders thereof of separate promissory notes (each an "Interest
Note," and, collectively, the "Interest Notes"), in each case having a principal
amount equal to the amount of interest due and payable on such holder's
outstanding Notes on such interest payment date, or (y) in cash; provided that
                                                                 --------
the Company will only be entitled to pay such interest in cash if it has
irrevocably notified in writing the holders of the Notes of its intention to
make a cash interest payment at least ten (10) Business Days before the relevant
interest payment date, it being agreed that payment in kind via Interest Notes
is the default interest payment method in the absence of such notice.  Interest
on Interest Notes shall accrue at the same Interest Rate per annum and shall be
payable in kind by the issuance of additional Interest Notes or in cash as
provided above on the same date as interest is payable in kind or in cash as
provided above on the Notes.  The unpaid principal balance of all Notes
(including Interest Notes), together with accrued but unpaid interest thereon,
shall be due and payable in cash on the stated date of maturity of the Notes.
<PAGE>
 
Notwithstanding different issue dates, unless the context clearly requires
otherwise, all Interest Notes shall be Notes for all purposes of this Agreement.
The Notes will bear interest on overdue principal (including any overdue
required or optional prepayment of principal) and premium, if any, and (to the
extent legally enforceable) on any overdue installment of interest at the
Interest Rate from the date such payment is due, whether by acceleration or
otherwise, until paid.  The Notes (including the Interest Notes) will mature on
April 28, 2000, and will be substantially in the form attached hereto as Exhibit
A.  Interest on the Notes shall accrue and be computed semi-annually on the
basis of a 360-day year of twelve 30-day months.  The term "Notes" as used
herein shall include each Note (including each Interest Note) delivered at any
time pursuant to this Agreement.  The terms that are capitalized herein shall
have the meanings set forth in Section 8.1 hereof unless the context shall
otherwise require or unless they are defined elsewhere herein.  The Notes
(including Interest Notes) will be senior secured obligations of the Company,
ranking pari passu in right of payment with all permitted existing and permitted
        ---- -----
future senior secured Indebtedness of the Company and senior to all unsecured or
subordinated Indebtedness of the Company, all non-permitted senior secured
indebtedness of the Company and all other senior indebtedness of the Company.

     Section 1.2.   Commitment, Closing Date.  Subject to the terms and
conditions hereof and on the basis of the representations and warranties
hereinafter set forth in this Agreement and in Exhibit C hereto, the Company
agrees to issue and sell to each Purchaser, and each Purchaser agrees to
purchase from the Company, the aggregate principal amount of Notes set forth
opposite such Purchaser's name on Schedule I attached hereto by delivery of the
Purchase Price for such Notes as set forth on Schedule I.  On the Closing Date
(as defined below), the Company also shall deliver to the Purchasers, pro rata
                                                                      --- ----
in proportion to the number of Notes they purchase on the Closing Date, Warrants
to purchase an aggregate of 537,500 shares of the Company's Series D Preferred
Stock, par value $.0001 per share (the "Preferred Stock") substantially in the
form of Exhibit B hereto (the "Warrants") and registered in the name of each
Purchaser or its nominee and in such denominations as reasonably requested by
such Purchaser.  Delivery of the Notes and Warrants will be made at the offices
of Kleinberg, Kaplan, Wolff & Cohen, P.C. against payment therefor, pursuant to
the wiring instructions set forth on the Company's signature page S-1 to this
Agreement, in immediately available funds in an amount equal to the Purchase
Price at 3 P.M., Eastern time on April 28, 1998 (the "Closing Date").  The Notes
delivered to each Purchaser on the Closing Date will be registered in the name
of such Purchaser or in the name of such nominees and in such denominations as
such Purchaser may specify no later than two Business Days prior to the Closing
Date and in substantially the form attached hereto as Exhibit A.

     Section 1.3.   Additional Warrants.

               (a)  In the event that the Company offers or sells certain Stock,
or certain securities convertible into or exchangeable or exercisable for Stock,
whether in a public or private offering, while any Notes or Warrants are
outstanding and such Stock is valued (based on the consideration directly
received by the Company upon such sale, conversion or exchange) at less than
$9.25 per share (as presently constituted), then the Company shall issue
additional Warrants to then holders of the Warrants and adjust the Warrant
exercise price, all as set forth in the Warrants.
<PAGE>
 
               (b)  On the twelve month anniversary of the Closing Date, and at
the end of each subsequent ninety (90) day period, until the Company has
completed an Initial Public Offering and redeemed at least one-half of all
issued and outstanding Notes (including Interest Notes, if any), the Company
will issue to then holders of Notes additional Warrants to purchase two hundred
thousand (200,000) shares of Preferred Stock (pro rata in proportion to the
principal amount of the Notes then held by the Note holders).

     Section 1.4.   Limits on Rate of Return.  The Company may redeem and
repurchase from the Purchasers and all subsequent holders of the Notes, the
Warrants and any shares of Preferred Stock issued upon exercise of the Warrants
(the "Preferred Shares") all such Notes, Warrants and Preferred Shares if and
only if, on or before the earlier of (a) the closing of the Company's first
Initial Public Offering, or (b) April 28, 1999, time being of the essence, the
Company shall have completed in all respects the redemption and repurchase of
and payment in full for any and all Notes, Warrants and Preferred Shares for an
aggregate redemption and repurchase price of $40,600,000 in cash (subject to
equitable increase upon the occurrence of any of the adjustment events specified
in Section 5 of the Warrants), such redemption price to be allocated first to
the redemption of the Notes at their face value, then to the redemption of the
Preferred Shares at their liquidation value, and any excess to the redemption of
the Warrants.  This right is (a) subject to the Company's obligation to give all
record holders of the Notes, Warrants and Preferred Shares as much notice as is
reasonably possible (but in no event less than 15 Business Days' notice) of its
intention to so redeem and repurchase on or before April 28, 1999; (b) further
subject, if the Company is to use all or part of the proceeds from an Initial
Public Offering for such redemption, to the Company's affirmative obligation to
so inform all such record holders on the first day following the day a
registration statement relating to the Initial Public Offering is first filed
(in preliminary, final, confidential or other form) with the Securities and
Exchange Commission; and (c) further subject to the receipt by the holders of
the Notes, the Warrants and the Preferred Shares of an opinion of outside
counsel to the Company, in form and content satisfactory to such holders, that
such redemption and payment (i) does not violate the charter, by-laws or any
agreement to which the Company is a party or by which its property is bound,
(ii) is not in violation of any law, rule, regulation or statute, and (iii) is
not a void or voidable (or similar) transfer under applicable federal or state
law (and a representation of the Company to that effect is also given to such
holders).  To the extent the Company is obligated to give notice under (a) above
after its Initial Public Offering, it may also give notice to the public via a
press release.  With respect to any Warrants, Warrant Shares or Common Shares
which have been sold by a Purchaser prior to the completion of the redemption
set forth in this Section 1.4, such Warrants, Warrant Shares and Common Shares
shall be subject to the Company's redemption rights in this Section 1.4.

SECTION 2. REDEMPTION OF NOTES.

     Section 2.1.   Optional Redemption.  The Company may at any time and from
time to time and at its option redeem all or, on a pro-rata basis, less than all
(but not less than one-half of all) the then outstanding Notes (including
Interest Notes) by (a) payment in cash of the aggregate principal amount thereof
plus all accrued and unpaid interest thereon to the date of such 
<PAGE>
 
redemption, plus (b) the issuance of all Warrants required to be issued
hereunder and under the Warrants on or before such redemption date. The Company
may also redeem all or part of the Notes as provided in Sections 5.9(viii) and
5.14.

     Section 2.2.   Notice of Redemption.  The Company will give irrevocable
written notice of any redemption of the Notes pursuant to Section 2.1 to the
holders thereof not less than 30 days nor more than 60 days before the date
fixed for such redemption specifying (a) such date, (b) the aggregate principal
amount of the Notes to be redeemed, (c) accrued and unpaid interest, if any,
payable to the redemption date and (d) Warrants required to be issued pursuant
to Section 2.1(b).  Notice of redemption having been so given, the aggregate
principal amount (or portion thereof) specified in such notice, together with
accrued and unpaid interest, if any, shall become due and payable, and such
Warrants shall become issuable, on the redemption date.

     Section 2.3.   Mandatory Redemption.

               (a)  Upon the completion of an Initial Public Offering, the
Company shall redeem one-half of the aggregate principal amount of the Notes
(including Interest Notes) outstanding, together with accrued but unpaid
interest thereon, pro rata among the holder of the Notes.

               (b)  As soon as reasonably practicable, but in no event later
than the date following the date on which the registration statement related to
the Initial Public Offering is first filed with the Securities and Exchange
Commission (in preliminary, final, confidential or other form), the Company
shall give the holders of Notes written notice (containing reasonable detail) of
the Company's intention (subject to the successful completion of the Initial
Public Offering) as to the use of the proceeds of such Initial Public Offering
with respect to the Notes, including as to the optional redemption of any Notes
in excess of the one-half to be mandatorily redeemed pursuant to paragraph
2.3(a).

     Section 2.4.   Change of Control.  Upon the public announcement or other
notification pursuant to this Section 2.4 of a Change of Control transaction, a
holder of Notes will, at any time after such public announcement or
notification, have the right to cause the Company to redeem all or part of such
holder's outstanding Notes by payment by the Company in respect of such redeemed
Notes to such holder in immediately available funds by wire transfer equal to
101% of the principal amount plus accrued but unpaid interest on such Notes.
The Company, upon learning of the impending Change of Control transaction, will
promptly notify the holders of Notes in writing of any impending Change of
Control transaction, specifying in reasonable detail all material terms thereof.
If such notice is given after the Initial Public Offering, the Company may also
inform the public and the markets via a press release.  Upon any such request
for redemption by a holder of the Notes under this Section 2.4, the Company
shall so redeem such holder's Notes within three Business Days of that request.

SECTION 3. REPRESENTATIONS.

     Section 3.1.   Representations of the Company.  The Company represents and
warrants that all representations and warranties set forth in the form of
certificate attached hereto as Exhibit C are true and correct as of the date
hereof, and shall be true and correct on the Closing Date, and agrees that all
such representations and warranties are incorporated herein by reference with
the same force and effect as though herein set forth in full.

     Section 3.2.   Representations of the Purchasers.  Each Purchaser severally
represents, warrants and agrees for itself only that:

               (a)  Such Purchaser is acquiring its Notes for the purpose of
investment for the Purchaser's own account and not with a view to the resale or
distribution thereof, and that such Purchaser has no present intention of
selling, negotiating or otherwise disposing of its Notes except in accordance
with applicable securities laws.

               (b)  No part of the funds to be used by such Purchaser to
purchase the Notes constitutes assets allocated to any "separate account"
maintained by it. As used in this Section 3.2(b), the term "separate account"
shall have the meaning assigned to it in ERISA.

               (c)  Such Purchaser is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization with all
requisite power and authority to execute, deliver and perform its obligations
under this Agreement and to consummate the transactions contemplated hereby.

               (d)  No approval, consent or withholding of objection on the part
of any regulatory body, state, federal or local, or any other third party is
necessary in connection with the execution by such Purchaser of the Agreement or
its acceptance of its Notes or compliance by such Purchaser with any of the
provisions of the Agreement or the Notes, unless such consent or approval has
already been obtained.

               (e)  The execution, delivery and performance by such Purchaser of
this Agreement and all other instruments and documents to be executed and
delivered by such Purchaser in connection herewith are not (and will not be or
result) in material conflict with or in material contravention or material
violation of any law (including common law), rule or regulation by which such
Purchaser is bound or to which it is subject or any material agreement to which
it is a party.

               (f)  The Company has advised the Purchaser that the Notes have
not been registered under the Securities Act of 1933, as amended (the
"Securities Act"), or any state securities laws by reason of a specific
exemption from the registration provisions of the Securities Act which depends
upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Purchaser's representations as expressed herein, and the Notes
may not be sold, transferred or otherwise disposed of by such Purchaser without
such registration or an exemption therefrom. The Purchaser understands that the
Securities are "restricted securities" under applicable U.S. federal and state
securities laws and that, pursuant to these laws, the
<PAGE>
 
Purchaser must hold the Securities indefinitely unless they are registered with
the Securities and Exchange Commission and qualified by state authorities, or an
exemption from such registration and qualification requirements is available.
Such Purchaser is either an accredited investor within the meaning of Rule 501
of the Securities Act or a qualified institutional buyer within the meaning of
Rule 144A of the Securities Act.

                    (i)   The Purchaser is aware of the Company's business
affairs and financial condition only to the extent disclosed in writing to the
Purchaser by the Company. Nothing in this Section 3.2(g) shall limit the rights
of any Purchaser or its assignees or successors in interest to rely on the
representations, warranties and covenants of the Company without investigation.

                    (ii)  The Purchaser understands that no public market now
exists for any of the securities issued by the Company, and that the Company has
made no assurances that a public market will ever exist for the Notes.

                    (iii) The Purchaser understands that the Notes, Warrants and
Preferred Shares, and any securities issued in respect thereof or exchange
therefor, may bear the legends shown on the forms attached hereto as exhibits.
The parties agree that such legend(s) shall be removed at such time as, in the
reasonable judgment of counsel for the Company, or as in the reasonable opinion
delivered to the Company of counsel to such Purchaser or holder, they are no
longer required by law.

remaining portion, which remaining portion shall remain in force and effect as
if this Agreement had been executed with the invalid or unenforceable portion
thereof eliminated (or, if possible, rewritten to the extent necessary to
eliminate such invalidity or unenforceability) and it is hereby declared the
intention of the parties hereto that they would have executed the remaining
portion of this Agreement without including therein any such part, parts or
portion which may, for any reason, be hereafter declared invalid or
unenforceable.

     Section 9.8.  Like Treatment of Holders. Neither the Company nor any of
its Affiliates shall, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee, payment for redemptions or
exchanges of Notes, or otherwise, to any holder of any Notes, for or as an
inducement to, or in connection with the solicitation of, any consent, waiver or
amendment of any terms or provisions of the Notes or this Agreement or the
Warrants, unless such consideration is required to be paid to all holders of
Notes bound by such consent, waiver or amendment whether or not such holders so
consent, waiver or agree to amend and whether or not such holders tender their
Notes for redemption or exchange.  The Company shall not, directly or
indirectly, redeem any Notes unless such offer of redemption is made pro rata to
all holders of Notes on identical terms.

     Section 9.9.  Governing Law. This Agreement and the notes and warrants
issued and sold hereunder shall be governed by and construed and enforced in
accordance with the laws of the State of New York, as applied to contracts made
and performed entirely within the State of New York.  Each party hereto hereby
submits to the exclusive jurisdiction of the United States District Court for
the Southern District of New York or the State Courts of New York sitting in New
York County for purposes of all legal proceedings arising out of or relating to
this Agreement and the notes or the transactions contemplated hereby.  Each
party hereto irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding
brought in such a court has been brought in an inconvenient forum.  If any
provision of this agreement is determined to be unenforceable under the laws of
the State of New York, and if such provision would be enforceable under the laws
of the State of Washington, then it is agreed that the Courts of the State of
New York shall interpret and enforce such provision pursuant to the laws of the
State of Washington.

     Section 9.10. Captions. The descriptive headings of the various Sections
or parts of this Agreement are for convenience only and shall not affect the
meaning or construction of any of the provisions hereof.

     Section 9.11. Brokerage Fees. BT Alex. Brown Incorporated has acted as
agent for the Company in connection with the transactions contemplated hereby
and is being paid a commission by the Company pursuant to a separate letter
agreement.

     Section 9.12. Intentionally Left Blank.

     Section 9.13. Possible Future Notes. If the Company's revenues, expenses,
cash flow and other material financial projections for the year ending December
31, 1998 are within ten percent of the revenues, etc. projected in the projected
budget provided to and accepted in writing by the Purchasers prior to the date
hereof, and if in the Purchasers' judgment neither the Company nor any
        ---
Subsidiary, if any, has experienced or is likely to experience an event
materially adverse to the profits, revenues, prospects, operations or condition
of the Company or such Subsidiary, and if the Purchasers are otherwise satisfied
                                   ---
with the adequacy of the Collateral, 
<PAGE>
 
and if no Default or Event of Default then exists hereunder or under the
- ---
Warrants or the Security Agreement, and if the representations and warranties
                                    ---
made by the Company herein are true and correct on and as of December 31, 1998
and on and as of each day thereafter until the completion of the new purchase
referred to below, and if the Company has not yet completed an Initial Public
                   --- 
Offering, and if the Company has not exercised or expressed its intention to
          ---
exercise its redemption and repurchase right under Section 1.4 hereof, then, if
and only if the Company so chooses, the Purchasers will purchase from the
Company (assuming all the conditions of this Section 9.13 are satisfied), and
the Company will sell to the Purchasers as soon as reasonably practicable after
the later of April 28, 1999 or the date the Purchasers receive the Company's
audited financial statements for the year ended December 31, 1998, and using
documents substantially similar to those used in these transactions, up to an
additional $8 million in aggregate principal amount of new Notes; provided such
                                                                  --------
new Notes will in all respects (except for the accrual and payment of interest
between April 28, 1998 and the actual date of their issuance, which accrual and
payment shall be suspended through the date of such issuance) be treated as if
they had been issued on April 28, 1998. For example, on the 12 month anniversary
of the Closing Date, such new Notes would experience a 200 basis point increase
in the Base Interest Rate. Additional Warrants to purchase 148,276 additional
Preferred Shares (as the same may be adjusted from the date hereof under the
terms of the Warrants) shall be issued in respect of such new Notes, such
Warrants to be dated the Closing Date. Should any dispute arise as to the
meaning, intention or interpretation of any term or provision of this Section
9.13, the determination thereof by MacKay-Shields Financial Corporation shall be
final and binding on all parties to this Agreement. The Company acknowledges and
agrees that it shall be bound by any such determination of MacKay-Shields
Financial Corporation; or if the Company does not agree with such determination,
it shall have the right, as its sole and exclusive remedy, to treat all (but not
less than all) of the terms and provisions of this Section 9.13 as null and void
and of no force and effect. Any action by the Purchasers, or any exercise by the
Purchasers of their judgment or requiring the Purchasers to be satisfied, under
this Section 9.13 shall require the consent of all of the Purchasers.

     The execution hereof by you shall constitute a contract between us for the
uses and purposes hereinabove set forth, and this Agreement may be executed in
any number of counterparts, each executed counterpart constituting an original
but all together only one agreement.

            13.75% Senior Secured Bridge Note Due April [  ], 2000


                          No. ______  April [  ],1998


METAWAVE COMMUNICATIONS CORPORATION, a Delaware corporation (the "Company"), for
                   value received, hereby promises to pay to

                                [______________]

                             or registered assigns
                       on the [     ] day of April, 2000
                            the principal amount of
                [__________________________________] ($_______)


     Interest on this Note will accrue at a rate equal to the lower of (i)
13.75% per annum (as adjusted in accordance with the following sentence, the
"Base Interest Rate") or, (ii) the highest rate permitted by law (such lower
amount being referred to as the "Interest Rate"), and be payable semi-annually
on April [  ] and October [  ] of each year, commencing on October [  ], 1998,
and at maturity.  On April [  ], 1999, and at the end of each subsequent one
hundred eighty (180) day period, the Base Interest Rate will increase by 200
basis points, to a maximum interest rate of 18.0%.  Interest on this Note shall
accrue and be computed semi-annually on the basis of a 360-day year of twelve
30-day months.

     The interest shall be payable at the option of the Company (x) in kind by
the issuance to the holders thereof of separate promissory notes (each an
"Interest Note," and, collectively, the "Interest Notes"), in each case having a
principal amount equal to the amount of interest due and payable on such date or
(y) in cash; provided that the Company will only be entitled to pay in cash if
it has irrevocably notified in writing the holders of the Notes of its intention
to make a cash interest payment at least ten (10) Business Days before the
relevant interest payment date, it being agreed that payment in kind via
Interest Notes is the default interest payment method in the absence of such
notice. Interest on Interest Notes shall accrue at the same Interest Rate per
annum and shall be payable in kind by the issuance of additional Interest Notes
or in cash as provided above on the same date as interest is payable on the
Notes. The unpaid principal balance of all Notes (including Interest Notes),
together with unpaid accrued interest thereon, shall be due and payable in cash
on the stated date of maturity of the Notes. Such Interest Notes shall be
substantially in the form of this Note. Notwithstanding different issue dates
and interest terms, unless the context clearly requires otherwise, all Interest
Notes shall be Notes for all purposes of the Agreement.

any overdue required or optional prepayment of principal) and premium, if any,
and (to the extent legally

                                      -2-

annum from the date such payment is due, whether by acceleration or otherwise,
until paid. At maturity or upon any acceleration of this Note, the principal
hereof and accrued but unpaid interest hereon are payable at the principal
office of the Company at 8700 148th Avenue NE, Redmond, Washington 98052 in

the time of payment shall be legal tender for the payment of public and private
debts.

of this Note becomes due and payable on any date which is not a Business Day,
such amount shall be payable on the next preceding Business Day.  "Business Day"
means any day other than a Saturday, Sunday, statutory holiday or other day on

     2.   EXERCISE OF WARRANT.
          ------------------- 

     This Warrant may be exercised by the Warrant Holder, in whole or in part,
at any time and from time to time by either of the following methods:

          (a)  The Warrant Holder may surrender this Warrant, together with the
form of subscription at the end hereof duly executed by Warrant Holder
("SUBSCRIPTION NOTICE"), at the offices of the Company or any transfer agent for
the Preferred Stock; or

          (b)  The Warrant Holder may also exercise this Warrant, in whole or in
part, in a "cashless" or "net-issue" exercise by delivering to the offices of
the Company or any transfer agent for the Preferred Stock this Warrant, together
with a Subscription Notice specifying the number of Warrant Shares to be
delivered to such Warrant Holder ("DELIVERABLE SHARES") and the number of
Warrant Shares with respect to which this Warrant is being surrendered in
payment of the aggregate Purchase Price for the Deliverable Shares ("SURRENDERED
SHARES"); provided that the Purchase Price multiplied by the number of
Deliverable Shares shall not exceed the value of the Surrendered Shares; and
provided further that the sum of the number of Deliverable Shares and the number
of Surrendered Shares so specified shall not exceed the aggregate number of
Warrant Shares represented by this Warrant. For the purposes of this provision,
each Warrant Share as to which this Warrant is surrendered will be attributed a
value equal to the fair market value (as defined below) of the Warrant Share
minus the Purchase Price of the Warrant Share.

     In the event that the Warrant is not exercised in full, the number of
Warrant Shares shall be reduced by the number of such Warrant Shares for which
this Warrant is exercised and/or surrendered, and the Company, at its expense,
shall within five (5) Business Days issue and deliver to or upon the order of
Warrant Holder a new Warrant of like tenor in the name of Warrant Holder or as
Warrant Holder (upon payment by Warrant Holder of any applicable transfer taxes)
may request, reflecting such adjusted Warrant Shares.

                                      -2-
<PAGE>
 
     3.   DELIVERY OF STOCK CERTIFICATES.
          ------------------------------ 

          a)   Subject to the terms and conditions of this Warrant, as soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within five (5) Business Days thereafter, the Company shall transmit the
certificates (together with any other stock or other securities or property to
which Warrant Holder is entitled upon exercise) by messenger or overnight
delivery service to reach the address designated by such holder within five (5)
Business Days after the receipt of the Subscription Notice ("B+5").  If such
certificates are not received by the Warrant Holder within B+5, then the Warrant
Holder will be entitled to revoke and withdraw its exercise of its Warrant at
any time prior to its receipt of those certificates.

          b)   This Warrant may not be exercised as to fractional shares of
Preferred Stock.  In the event that the exercise of this Warrant, in full or in
part, would result in the issuance of any fractional share of Preferred Stock,
then in such event the Warrant Holder shall be entitled to cash equal to the
fair market value of such fractional share.  For purposes of this Warrant, "fair
market value" shall equal the closing trading price of the Common Stock on the
New York Stock Exchange, or the American Stock Exchange or the Nasdaq Stock
Market, whichever market (any, an "APPROVED MARKET") is the principal trading
exchange or market for the Common Stock (the "PRINCIPAL MARKET") on the date of
determination, multiplied by the aggregate number of shares of Common Stock into
which such Preferred Shares may then be converted, or, if the Common Stock is
not listed or admitted to trading on any Approved Market, the average of the
closing bid and asked prices on the over-the-counter market as furnished by any
New York Stock Exchange member firm reasonably selected from time to time by the
Company for that purpose and reasonably acceptable to the Warrant Holder,
multiplied by the aggregate number of shares of Common Stock into which such
Preferred Shares may then be converted, or, if the Common Stock is not listed or
admitted to trading on any Approved Market or traded over-the-counter and the
average price cannot be determined as contemplated above, the fair market value
of the Preferred Stock shall be as reasonably determined in good faith by the
Company's Board of Directors with the concurrence of the Warrant Holder.

     4.   (A)  REPRESENTATIONS AND COVENANTS OF THE COMPANY.
               -------------------------------------------- 

          a)   The Company shall comply with its obligations under Section 6
with respect to the Warrant Shares and the Common Stock issuable upon conversion
of the Warrant Shares ("COMMON SHARES"), including, without limitation, the
Company's obligation, subject to Section 6(a) below, to include the Warrant
Shares and the Common Shares in any registration statement registering the
Warrant Shares and/or the Common Shares under the Securities Act of 1933, as
amended (the "ACT").

          b)   The Company shall take all necessary action and proceedings as
may be required and permitted by applicable law, rule and regulation, including,
without limitation (after the Initial Public Offering) the notification of the
Principal Market, for the legal and valid issuance of this Warrant and the
Warrant Shares to the Warrant Holder under this Warrant and the Common Shares
under the Warrant Shares.

                                      -3-
<PAGE>
 
          c)   From the date of the Initial Public Offering through the last
date on which this Warrant is exercisable, the Company shall take all steps
necessary to insure that the Preferred Stock and the Common Stock remains listed
on the Principal Market.

          d)   The Warrant Shares, when issued in accordance with the terms
hereof, and the Common Shares, when issued in accordance with the terms of the
Warrant Shares, will be duly authorized and, when paid for or issued in
accordance with the terms hereof and thereof, shall be validly issued, fully
paid and non-assessable.  The Company has authorized and reserved for issuance
to Warrant holders and Warrant Share holders the requisite number of shares of
Preferred Stock and Common Stock to be issued pursuant to this Warrant and
pursuant to the Warrant Shares.

          e)   The Company shall at all times, commencing within five days from
the date hereof, reserve and keep available, solely for issuance and delivery as
Warrant Shares hereunder and as Common Shares under the Warrant Shares, one and
one-half times such number of shares of Preferred Stock and one and one-half
times such number of shares of Common Stock as shall from time to time be
issuable hereunder and thereunder.

          f)   The Company agrees to use its reasonable best efforts to promptly
provide to the holders of this Warrant, and the holders of the Warrant Shares,
and the holders of the Common Shares, from time to time upon request the
information required under Rule 144A under the Securities Act, so as to permit a
sale at such time or times of the Warrant and/or the Warrant Shares and/or the
Common Shares under said Rule 144A.

          g)   With a view to making available to Warrant holders, the holders
of Warrant Shares and the holders of Common Shares the benefits of Rule 144
promulgated under the Act and any other rule or regulation of the Securities and
Exchange Commission ("SEC") that may at any time permit Warrant holders, the
holders of Warrant Shares and the holders of Common Shares to sell securities of
the Company to the public without registration, the Company agrees to use its
reasonable best efforts after the Initial Public Offering to:

               i)    make and keep public information available, as those terms
are understood and defined in Rule 144, at all times;

               ii)   file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the Securities Exchange Act
of 1934, as amended (the "EXCHANGE ACT"); and

               iii)  furnish to any such holder forthwith upon request a written
statement by the Company that it has complied with the reporting requirements of
Rule 144 and of the Act and the Exchange Act, a copy of the most recent annual
or quarterly report of the Company, and such other reports and documents so
filed by the Company as may be reasonably requested to permit any such holder to
take advantage of any rule or regulation of the SEC permitting the selling of
any such securities without registration.

          h)   The Company covenants and represents that, so long as any of the
Warrants or the Warrant Shares are outstanding (i) the Company will not take any
action which will impair or otherwise weaken the rights and privileges of the
holders of the Warrants and the

                                      -4-
<PAGE>
 
Warrant Shares and (ii) the Company will deliver to the holders of the Warrants
and Warrant Shares, at the same time as same is required to be delivered to
Investors under the Investors' Rights Agreement, the financial statements of
other documents and information referred to in Section 2.1 of the Investors'
Rights Agreement.

          (B)  REPRESENTATIONS AND COVENANTS OF THE PURCHASER.
               ---------------------------------------------- 

          The Purchaser shall not transfer Warrant Shares, unless such transfer
is pursuant to an effective registration statement under the Act or pursuant to
an applicable exemption from such registration requirements.

     5.   ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES.  The number of and
          -------------------------------------------------                    
kind of securities purchasable upon exercise of this Warrant and the Purchase
Price shall be subject to adjustment from time to time as follows:

          a)   Subdivisions, Combinations and other Issuances.  If the Company
               ----------------------------------------------                 
shall at any time after the date hereof but prior to the expiration of this
Warrant subdivide its outstanding securities as to which purchase rights under
this Warrant exist, by split-up, spin-off, or otherwise, or combine its
outstanding securities as to which purchase rights under this Warrant exist, the
number of Warrant Shares as to which this Warrant is exercisable as of the date
of such subdivision, split-up, spin-off or combination shall forthwith be
proportionately increased in the case of a subdivision, or proportionately
decreased in the case of a combination. Appropriate proportional adjustments
(decrease in the case of subdivision, increase in the case of combination) shall
also be made to the Purchase Price payable per share, so that the aggregate
Purchase Price payable for the total number of Warrant Shares purchasable under
this Warrant as of such date shall remain the same as it would have been before
such subdivision or combination.

          b)   Stock Dividend. If at any time after the date hereof the Company
               --------------                                                  
declares a dividend or other distribution on Preferred Stock payable in
Preferred Stock or other securities or rights convertible into Preferred Stock
("PREFERRED STOCK EQUIVALENTS") without payment of any consideration by holders
of Preferred Stock for the additional shares of Preferred Stock or the Preferred
Stock Equivalents (including the additional shares of Preferred Stock issuable
upon exercise or conversion thereof), then the number of shares of Preferred
Stock for which this Warrant may be exercised shall be increased as of the
record date (or the date of such dividend distribution if no record date is set)
for determining which holders of Preferred Stock shall be entitled to receive
such dividends, in proportion to the increase in the number of outstanding
shares (and shares of Preferred Stock issuable upon conversion of all such
securities convertible into Preferred Stock) of Preferred Stock as a result of
such dividend, and the Purchase Price shall be proportionately reduced so that
the aggregate Purchase Price for all the Warrant Shares issuable hereunder
immediately after the record date (or on the date of such distribution, if
applicable), for such dividend shall equal the aggregate Purchase Price so
payable immediately before such record date (or on the date of such
distribution, if applicable).

          c)   Other Distributions.  If at any time after the date hereof the
               -------------------                                           
Company distributes to holders of its Preferred Stock, other than as part of its
dissolution, liquidation or the winding up of its affairs, any shares of its
capital stock, any evidence of indebtedness or any of its assets (other than
Preferred Stock), then the number of Warrant Shares for which this Warrant 

                                      -5-
<PAGE>
 
is exercisable shall be increased to equal: (i) the number of Warrant Shares for
which this Warrant is exercisable immediately prior to such event, (ii)
multiplied by a fraction, (A) the numerator of which shall be the fair market
value per share of Preferred Stock on the record date for the dividend or
distribution, and (B) the denominator of which shall be the fair market value
price per share of Preferred Stock on the record date for the dividend or
distribution minus the amount allocable to one share of Preferred Stock of the
value (as jointly determined in good faith by the Board of Directors of the
Company and the Warrant Holder) of any and all such evidences of indebtedness,
shares of capital stock, other securities or property, so distributed. The
Purchase Price shall be reduced to equal: (i) the Purchase Price in effect
immediately before the occurrence of any event (ii) multiplied by a fraction,
(A) the numerator of which is the number of Warrant Shares for which this
Warrant is exercisable immediately before the adjustment, and (B) the
denominator of which is the number of Warrant Shares for which this Warrant is
exercisable immediately after the adjustment.

          d)   Merger, etc. If at any time after the date hereof there shall be
               -----------                                                     
a merger or consolidation of the Company with or into or a transfer of all or
substantially all of the assets of the Company to another entity, then the
Warrant Holder shall be entitled to receive upon or after such transfer, merger
or consolidation becoming effective, and upon payment of the Purchase Price then
in effect, the number of shares or other securities or property of the Company
or of the successor corporation resulting from such merger or consolidation,
which would have been received by Warrant Holder for the shares of stock subject
to this Warrant had this Warrant been exercised just prior to such transfer,
merger or consolidation becoming effective or to the applicable record date
thereof, as the case may be.  The Company will not merge or consolidate with or
into any other corporation, or sell or otherwise transfer its property, assets
and business substantially as an entirety to another corporation, unless the
corporation resulting from such merger or consolidation (if not the Company), or
such transferee corporation, as the case may be, shall expressly assume, by
supplemental agreement reasonably satisfactory in form and substance to the
Warrant Holder, the due and punctual performance and observance of each and
every covenant and condition of this Warrant to be performed and observed by the
Company.

          e)   Reclassification, etc.  If at any time after the date hereof
               ---------------------                                       
there shall be a reorganization or reclassification of the securities as to
which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, then the Warrant Holder
shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified herein and upon payment of the Purchase Price then in
effect, the number of shares or other securities or property resulting from such
reorganization or reclassification, which would have been received by the
Warrant Holder for the shares of stock subject to this Warrant had this Warrant
at such time been exercised.

          f)   Warrant Share Adjustment.  In the event that the Company issues
               ------------------------                                       
or sells any Additional Stock, as that term is defined in Section 4(d)(ii) of
Article IV of the Certificate at an effective purchase price per share of Common
Stock ("NEW PRICE") which is less than $9.25 per share ("FIXED PRICE"), as
adjusted for stock splits and stock dividends, then in each such case ("DILUTION
EVENT"), the number of Warrant Shares which may be purchased upon the exercise
of this Warrant shall be increased by multiplying the number of Warrant Shares
which may be purchased upon the exercise of this Warrant by a fraction, the
numerator of which is the Fixed Price minus the New Price and the denominator of
which is the New Price. However, to the

                                      -6-
<PAGE>
 
extent that a Dilution Event results, pursuant to the terms of the Certificate,
in the holder of this Warrant being entitled to purchase more Common Shares
("EXCESS SHARES") upon conversion of the Warrant Shares issuable hereunder into
Common Shares, then the additional number of Warrant Shares to which the holder
hereof would have been entitled to receive pursuant to the immediately preceding
sentence of this Section 5(f) with respect to such Dilution Event shall be
reduced by the number of Excess Shares to which the holder of this Warrant would
then be entitled to receive upon exercise of this Warrant and the conversion of
the Warrant Shares issuable hereunder into Common Shares.

     6.   PIGGYBACK REGISTRATIONS/MARKET STAND-OFF PROVISION.
          -------------------------------------------------- 

          a)   Right to Piggyback.  The Company covenants that the Warrant
               ------------------                                         
holders and the holders of the Warrant Shares shall at all times have the same
piggyback and other rights (other than demand registration rights referred to in
Sections 1.2 and 1.12 of the Investor's Rights Agreement) as a "Holder" and as a
"Series D Investor" as are contained in the Investors' Rights Agreement, which
rights are incorporated herein and made a part hereof.

          b)   Market Stand-Off Provision.  The holders of the Warrants and the
               ---------------------------                                     
Warrant Shares agree to be bound (as an "Investor") by the market stand-off
provisions contained in Section 1.15 of the Company's Investors' Rights
Agreement on condition that:  (i) all officers, directors and "control persons"
of the Company, and members of their immediately family, are and remain bound by
such provisions, (ii) all persons and entities who have registration rights
(piggy-back, demand or otherwise) of any kind with respect to the Company's
Stock are and remain bound by such provisions, and (iii) the Company enforces
such provisions against all the holders of the Warrants only to the same extent
and same degree that it enforces such provisions against all of the persons and
entities referred to in (i) and (ii) immediately above.  The Company
acknowledges that the term "donees" as used in said Section 1.15 shall include
successive transferees, assignees, participants and the like.

     7.   NO IMPAIRMENT.  The Company will not, by amendment of its Certificate
          -------------                                                        
of Incorporation or through any reorganization, transfer of assets,
consolidation, 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 of this Warrant or the terms of the Warrant Shares, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the Warrant Holder and the holder of the Warrant Shares against
impairment. Without limiting the generality of the foregoing, the Company (a)
will not increase the par value of any Warrant Shares above the amount payable
therefor on such exercise, and (b) will take all such action as may be
reasonably necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares on the exercise of
this Warrant and Common Stock upon conversion of the Warrant Shares.

     8.   NOTICE OF ADJUSTMENTS.  Whenever the Purchase Price or number of
          ---------------------                                           
Shares purchasable hereunder shall be adjusted pursuant to Section 5 hereof, the

     9.   RIGHTS AS STOCKHOLDER.  Prior to exercise of this Warrant, the Warrant
          ---------------------                                                 
Holder shall not be entitled to any rights as a stockholder of the Company with
respect to the Warrant Shares, including (without limitation) the right to vote
such shares, receive dividends or other distributions thereon or be notified of
stockholder meetings.  However, in the event of any taking by the Company 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 or other
distribution, 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 Company shall mail to each Warrant Holder, at least 10
Trading Days prior to the date specified therein, a 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.

     10.  LIMITATION ON EXERCISE.  Notwithstanding anything to the contrary
          ----------------------                                           
contained herein, this Warrant may not be exercised by the Warrant Holder to the
extent that, after giving effect to Warrant Shares to be issued pursuant to a
Subscription Notice, the total number of shares of Common  Stock deemed
beneficially owned by such holder (other than by virtue of ownership of this
Warrant, or ownership of other securities that have limitations on the holder's
rights to convert or exercise similar to the limitations set forth herein),
together with all shares of Common Stock deemed beneficially owned by the
holder's "affiliates" (as defined in Rule 144 of the Act) that would be
aggregated for purposes of determining whether a group under Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") exists,
would exceed 9.9% of the Common Shares issued and outstanding immediately
following such exercise (the "Restricted Ownership Percentage"); provided that
                                                                 --------     
(w) each Warrant Holder shall have the right at any time and from time to time
to reduce its Restricted Ownership Percentage immediately upon notice to the
Company or in the event of a Change of Control Transaction, (x) each Warrant
Holder shall have the right at any time and from time to time to increase its
Restricted Ownership Percentage or otherwise waive in whole or in part the
restrictions of this Section 10 upon 61 days' prior notice to the Company or
immediately in the event of a Change of Control Transaction, (y) each Warrant
Holder can make subsequent adjustments pursuant to (w) or (x) any number of
times from time to time (which adjustment shall be effective immediately if it
results in a decrease in the Restricted Ownership Percentage or shall be
effective upon 61 days' prior written notice or immediately in the event of a
Change of Control Transaction if it results in an increase in the Restricted
Ownership Percentage) and (z) each Warrant Holder may eliminate or reinstate
this limitation at any time and from time to time (which elimination will be
effective upon 61 days' prior notice and which reinstatement will be effective
immediately).  Without limiting the foregoing, in the event of a Change of
Control Transaction, any holder may reinstate immediately (in whole or in part)
the requirement that any increase in its Restricted Ownership Percentage be
subject to 61 days' prior written notice, notwithstanding such Change of Control
Transaction, without imposing such requirement on, or otherwise changing such
holder's rights with respect to, any other Change of Control Transaction.  For
this purpose, any material modification of the terms of a Change of Control
Transaction will be deemed to create a new Change of Control Transaction.  A
"CHANGE OF CONTROL TRANSACTION" will be deemed to have occurred upon the earlier
of the announcement or consummation of a transaction or series of transactions
involving (x) any consolidation or merger 
<PAGE>
 
of the Company with or into any other corporation or other entity or person
(whether or not the Company is the surviving corporation), or any other
corporate reorganization or transaction or series of related transactions in
which in excess of 50% of the Company's voting power is transferred through a
merger, consolidation, tender offer or similar transaction, or (y) in excess of
50% of the Company's Board of Directors consists of directors not nominated by
the prior Board of Directors of the Company, or (z) any person (as defined in
Section 13(d) of the Exchange Act, together with its affiliates and associates
(as such terms are defined in Rule 405 under the Act), beneficially owns or is
deemed to beneficially own (as described in Rule 13d-3 under the Exchange Act
without regard to the 60-day exercise period) in excess of 50% of the Company's
voting power. The delivery of a Subscription Notice by the Warrant Holder shall
be deemed a representation by such holder that it is in compliance with this
paragraph.

     11.  REPLACEMENT OF WARRANT.  On receipt of evidence reasonably
          ----------------------

UNDER THIS WARRANT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND

either's designee or any affiliate thereof, to sign the Company's name on
invoices or bills of lading, drafts against customers, notices of assignment,
verifications and schedules and, generally, to do all things necessary to carry

such attorney-in-fact may, at any time, notify the Postal Service authorities to

Secured Party or the Investment Advisor or either's designee.  The powers
granted herein, being coupled with an interest, are irrevocable until all of the
Obligations are irrevocably paid and discharged in full and this Agreement is
terminated.  No Secured Party, no Investment Advisor nor any attorney-in-fact

     4.  REMEDIES OF SECURED PARTY.

         4.01  ENFORCEMENT.  Upon the occurrence of any Event of Default, a
               -----------                                                 
Secured Party shall have, in addition to all of its other rights under this
Agreement by operation of law or otherwise (which rights shall be cumulative),
all of the rights and remedies of a secured party under the Uniform Commercial
Code and shall have the right to enter upon any premises where such Collateral
is kept and retake possession thereof.  Upon the occurrence of an Event of
Default, a Secured Party or the Investment Adviser or their designee may,
without demand, advertising or notice, all of which the Company hereby waives
(except as the same may be required by law), sell, lease, dispose of, deliver
and grant options to a third party to purchase, lease or otherwise dispose of
any and all Equipment, Inventory, Receivables, General Intangibles or other
security or Collateral held by it or for its account at any time or times in one
or more public or private sales or other dispositions, for cash, on credit or
otherwise, at such prices and upon such terms as such Secured Party, in its sole
discretion, deems advisable.  The Company agrees that if notice of sale shall be
required by law such requirement shall be met if such notice is mailed, postage
prepaid, to the Company at its address set forth above or such other address as
it may have, in writing, provided to the Secured Parties, at least five (5) days
before the time of such sale or dispositions.  Notice of any public sale shall
be sufficient if it describes the security or Collateral to be sold in general
terms, stating the amounts thereof, the nature of the business in which such
Collateral was created and the location and nature of the properties covered by
the other security interests or mortgages and the prior liens thereon.  A
Secured Party or the Investment Adviser or their designee may postpone or
adjourn any sale of any Collateral from time to time by an announcement at the
time and place of the sale to be so postponed or adjourned without being
required to give a new notice of sale.  A Secured Party or the Investment
Adviser or their designee may be the purchaser at any such sale if it is public,
free from any right of redemption, which the Company also waives, and payment
may be made, in whole or in part, in respect of such purchase price by the
application of the Obligations to the Secured Party.  The Company, with respect
to its property constituting such Collateral, shall be obligated for, and the
proceeds of sale shall be applied first to, the reasonable costs of retaking,
assembling, finishing, collecting, refurbishing, storing, guarding, insuring,
preparing for sale, and selling the Collateral, including the reasonable fees
and disbursements of attorneys, auctioneers, appraisers and accountants employed
by a Secured Party or the Investment Adviser or their designee.  Proceeds shall
then be applied to the payment, in whatever order such Secured Party or the
Investment Adviser or their designee may elect, of all of the Obligations.  Such
Secured Party shall return any excess to the Company or to whomever may be fully
entitled to receive the 

                                      -7-
<PAGE>
 
same or as a court of competent jurisdiction may direct. The Company shall
remain liable for any deficiency.

         4.02  WAIVER.  The Company waives any right, to the extent applicable
               ------                                                         
law permits, to receive prior notice of or a judicial or other hearing with
respect to any action or prejudgment remedy or proceeding by a Secured Party (or
the Investment Advisor or their designee) to take possession, exercise control
over, or dispose of any item of the Collateral in any instance (regardless of
where the same may be located) where such action is permitted under the terms of
this Agreement or by applicable law or of the time, place or terms of sale in
connection with the exercise of such Secured Party's rights hereunder and also
waives, to the fullest extent permitted by law, any bonds, security or sureties
required by any statute, rule or otherwise by law as an incident to any taking
of possession by such Secured Party or the Investment Adviser or their designee
of property subject to such Secured Party's lien.  The Company also waives any
damages (direct, consequential or otherwise) occasioned by the enforcement of a
Secured Party's rights under this Agreement including the taking of possession
of any Collateral all to the extent that such waiver is permitted by law and to
the extent that such damages are not caused by such Secured Party's bad faith or
willful misconduct.  These waivers and all other waivers provided for in this
Agreement have been negotiated by the parties and the Company acknowledges that
it has been represented by counsel of its own choice and has consulted such
counsel with respect to its rights hereunder.

         4.03  OTHER RIGHTS.  The Company agrees that no Secured Party shall
               ------------                                                 
have any obligation to preserve rights to any Collateral against prior parties
or to proceed first against any Collateral or to marshall any Collateral of any
kind for the benefit of any other creditors of the Company or any other Person.
Each Secured Party is hereby granted, to the extent that the Company is
permitted to grant a license or right of use, a license or other right to use,
without charge, labels, patents, copyrights, rights of use, of any name, trade
secrets, trade names, trademarks and advertising matter, or any property of a
similar nature of the Company as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and the
Company's rights under all licenses and any franchise, sales or distribution
agreements shall inure to each Secured Party's benefit.

         4.04  DISPOSITION OF PROCEEDS.  The proceeds of any sale or
               -----------------------                              
disposition of all or any part of the Collateral shall be applied by each
Secured Party in the following order: (i) to the payment in full of the costs
and expenses of such sale or sales, collections, and the protection, declaration
and enforcement of any security interest granted hereunder including the
compensation of such Secured Party's agents and attorneys; (ii) to the payment
of the Obligations; and (iii) to the payment to the Company of any surplus then
remaining from such proceeds, subject to the rights of any holder of a lien on
the Collateral of which such Secured Party has actual notice.  In the event that
the proceeds of any sale or other disposition of the Collateral are insufficient
to cover the principal of, and premium, if any, and interest on, the Obligations
secured thereby plus costs and expenses of the sale or other disposition, the
Company shall remain liable for any deficiency.

         4.05  EXPENSES.  The Company agrees that it shall pay all costs and

filings at all times, and such Secured Party's reasonable attorneys fees and
disbursements (regardless of whether any litigation is commenced, whether
default is declared hereunder, and regardless of tribunal or jurisdiction).

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
                        ON FINANCIAL STATEMENT SCHEDULE
 
  We have audited the financial statements of Metawave Communications
Corporation as of December 31, 1997 and 1996, and the related statements of
operations, shareholders' equity (deficit) and cash flows for the years then
ended and the period from January 19, 1995 (inception) to December 31, 1995,
and have issued our report thereon dated March 13, 1998, except for Note 13,
as to which the date is April 28, 1998, (included elsewhere in this
Registration Statement). Our audits also included the financial statement
schedule listed in Item 16(b) of this Registration Statement. This schedule is
the reponsibility of the Company's management. Our responsibility is to
express an opinion based on our audits.
 
  In our opinion, the financial statement schedule referred to above, when
