                               PROSPECTUS SUMMARY

   This summary highlights information found elsewhere in this prospectus. This
summary is not complete and does not contain all of the information you should
consider before investing in our common stock. Before deciding to invest in our
Class A common stock, you should read the entire prospectus carefully,
including "Risk Factors" and our financial statements and the notes to those
financial statements included elsewhere in this prospectus.

                         Western Multiplex Corporation

   We are a global provider of broadband, or high-speed, wireless access
systems that enable service providers, businesses and other enterprises to
deliver data, voice and video services. We believe our fixed wireless systems
address the growing need of our customers and end-users to rapidly and cost-
effectively deploy high-speed communication networks. During the last eight
years, we have developed proprietary technologies that have enabled us to
introduce what we believe are some of the fastest, longest range and most
reliable broadband wireless systems available, including our Lynx DS-3,
currently the industry's fastest license-exempt wireless system.

   Our systems operate in both the licensed and license-exempt portions of the
radio frequency spectrum. Our Lynx and Tsunami systems enable direct, or point-
to-point, fixed wireless communication between two locations. Our Lynx systems
are primarily used by wireless operators to connect their base stations to
other base stations and to existing wire line networks. Our Tsunami systems are
primarily used by service providers, businesses and other enterprises to expand
or establish private networks carrying Internet traffic among multiple
facilities. Our Ubiquity point-to-multipoint systems, which are currently under
development, will enable service providers, businesses and other enterprises to
connect multiple facilities within a geographic area to a central hub.

   We serve the global broadband wireless access market by selling our systems
to service providers, businesses and other enterprises directly through our
sales force and indirectly through distributors, value-added resellers and
systems integrators. In 1999, we sold our systems to 480 customers in 34
countries. Our customers include AT&T Wireless Group, Bell Atlantic
Corporation, GTE Corporation, Motorola Inc., Nextel Communications, Inc.,
Pacific Bell and Voicestream Wireless Corporation.

   Over the past decade, the amount of broadband data transmitted across
communications networks has grown significantly due to the increased use of the
Internet and bandwidth-intensive applications, which created an increase in
demand for cost-effective, high-speed communications. In addition, deregulation
in many countries has created an opportunity for new service providers to offer
broadband data, voice and video services. Although there are a number of
alternatives that deliver high-speed connections through existing wire line
technologies, these solutions are often expensive and time consuming to install
or unavailable. As a result, service providers, businesses and other
enterprises are increasingly looking to high-speed wireless technologies to
address the limitations of wire line solutions.

   Our broadband wireless access systems are used in a variety of applications
in different markets, including:

  .  Wireless operator infrastructure. Our wireless systems enable cellular
     and personal communication service providers to connect their base
     stations to other base stations and to existing wire line networks.

  .  Fiber extension. Our systems enable service providers to extend the
     reach of the fiber backbone with products that combine the high
     transmission speeds and reliability of fiber optic cable with the
     flexibility, cost effectiveness and rapid deployment of wireless
     technologies.

                                       1
<PAGE>


  .  Campus and other private networks. Our systems enable enterprises with
     multiple facilities, including those located in a campus environment, to
     connect their facilities to expand or establish private networks.

  .  Last mile access. Our systems connect end-users with a service
     provider's central office, providing high-speed last mile access.

   Our objective is to be a leading global provider of broadband wireless
access systems. Our strategy to accomplish this is to:

  .  Capitalize on our technology expertise to rapidly introduce new
     products;

  .  Utilize existing customer relationships to expand into new market
     segments;

  .  Increase our presence in international markets;

  .  Aggressively market through distributors, value-added resellers and
     systems integrators; and

  .  Expand through acquisitions.

   Our principal executive offices and manufacturing facilities are located at
1196 Borregas Avenue, Sunnyvale, California 94089. Our telephone number is
(408) 542-5200. The predecessor to our company was originally incorporated in
California on December 17, 1979. On November 1, 1999, the predecessor merged
into Western Multiplex Corporation, a Delaware corporation, with Western
Multiplex Corporation as the surviving entity in the merger.

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

                                  RISK FACTORS

   Investing in our common stock involves a high degree of risk. If any of the
following risks occur, our business, operating results and financial condition
could be harmed. You should carefully consider the following risk factors and
all other information contained in this prospectus before purchasing our common
stock.

Risks Related to Our Business

Our current operating results depend on the sale of our point-to-point Lynx and
Tsunami systems and, if these products become obsolete, our revenue may
decline.

   We currently derive substantially all of our revenue from our Lynx and
Tsunami systems and we expect that this will continue for the near future. If
the market demand for our Lynx and Tsunami systems declines, and we fail to
market or develop any new or enhanced products in a timely and cost-effective
manner, our revenue will decline. The market for broadband wireless access
systems is characterized by rapidly changing technology and evolving industry
standards. If the prices of existing broadband access solutions, including wire
line technologies, continue to decline, demand for our products is likely to
decrease. In addition, the introduction of new products or alternative
technologies by our competitors, many of whom have more extensive research and
development capabilities than we do, could render our products obsolete. As a
result, our revenue may decline.

If we do not complete development of our Ubiquity point-to-multipoint systems
on a timely basis or successfully introduce these systems, our prospects and
competitive position may significantly decline.

   Historically, our operations have focused on the point-to-point segment of
the broadband wireless access market. In an effort to remain competitive and
grow our business, we have recently decided to enter the point-to-multipoint
segment of the market.

   To enter this market, we acquired Ubiquity Communication, Inc. on March 24,
2000. Through the acquisition, we acquired point-to-multipoint technology that
will be used in our Ubiquity point-to-multipoint systems. We believe our future
prospects are dependent on our ability to successfully enter the point-to-
multipoint market with our Ubiquity products.

   Our point-to-multipoint products are still under development. As a result,
you should not rely on our recent results as an indication of our future
results in making an investment decision but should instead evaluate our
prospects in light of the risks, expenses and challenges we will encounter
because of our recent focus on this new market segment.

   Any delay in our schedule to introduce our point-to-multipoint products
could significantly harm our future prospects and competitive position. We do
not expect to begin beta testing, the final stage of development, for these
products until later in 2000, and we do not expect to ship them to customers
until 2001. We have experienced delays in the past in introducing new products
and product features and we may experience delays in the development of our
Ubiquity products that could prevent us from introducing these products on
schedule.

   In addition, if our Ubiquity point-to-multipoint products are not
competitive or if the commercial market for point-to-multipoint products does
not materialize, our revenues and future prospects will suffer. Even if our
Ubiquity products are available on a timely basis, other factors may impede the
success of our point-to-multipoint broadband wireless access solutions for our
customers. Moreover, some of our competitors already are selling point-to-
multipoint broadband wireless access systems, and there is often an advantage
to companies that are among the first to introduce new products.

                                       5

If we cannot manage the expansion of our international sales, our business
would be adversely affected.

   Sales outside the United States and Canada accounted for approximately 23%
of our sales in 1999. We expect to derive a greater portion of our revenue from
international markets in the future and to expand into new geographic markets.
Our failure to manage this expansion could lead to delays in sales and delivery
of our products, unanticipated costs and the diversion of management attention
and resources from our U.S. sales, which could cause our U.S. business to
decline. To successfully expand international sales, we must expand our
international operations, recruit additional international sales and support
personnel and expand our relationships with international distributors and
value-added resellers. This expansion will require significant management
attention and financial resources. Sales outside the United States also
frequently involve additional risks and difficulties, including:

  .  licenses, tariffs and other trade barriers imposed on our products;

  .  exchange rate fluctuation that may make our products more expensive to
     the end-users;

  .  extended collection time for receivables and reduced ability to enforce
     payment obligations;

  .  political and economic instability;

  .  compliance with a wide variety of regulatory laws relating to
     communications equipment;

  .  competition from local manufacturers that are subsidized or otherwise
     supported and protected by their government; and

  .  reduced protection for intellectual property in some countries.

If we are unable to develop products that comply with a wide range of
regulatory standards, we could lose sales.

   Because we sell our products in various countries, we are subject to
extensive regulation by both the United States and foreign governments. Many
countries require communications equipment used in their country to comply with
specific regulations, including safety regulations and radio frequency
allocation schemes and standards. Failure of our products to comply, or delays
in compliance, with the various regulations and standards could delay the
introduction or hinder the sale of our products.

   In addition, if compliance with regulatory standards in new foreign markets
proves to be more expensive or time consuming than we anticipate, we may
experience delays in filling orders and our customers may cancel their orders
or be deterred from placing orders with us in the future. As a result, we could
lose sales.

   Some countries have not yet completed their radio frequency allocation
process, and we therefore do not know the standards with which we will need to
comply in order to sell our products in those markets. Because we plan to
increase our international sales in the future, either directly through our
sales force or indirectly as our current customers enter new markets, it will
become increasingly important for us to develop and modify our products to
comply with the various regulations of each of the countries in which we sell
or plan to sell our products. We may not have experience with the regulatory
requirements of these new markets and, as a result, may encounter delays in
adapting our products to comply with the frequency requirements and other
regulatory requirements that exist in those markets.

Because we depend on single source and limited source suppliers for key
components, we could experience disruptions in supply that could delay or
decrease our revenue.

   We and our contract manufacturers depend on single or limited source
suppliers for several key components used in our products. Any disruptions in
the supply of these components could delay or decrease our revenues. In
addition, even for components with multiple sources, there have been, and may
continue to be, shortages due to capacity constraints caused by high demand. We
do not have any contracts with our suppliers. If, for any reason, a supplier
fails to meet our quality and quantity requirements or stops selling components
to us or our contract manufacturers at commercially reasonable prices, we could
experience significant production delays and cost increases, as well as higher
warranty expenses and product image problems. Because the

                                       6
<PAGE>

components with sole or limited sources are key components that are complex,
difficult to manufacture and require long lead times, we may have difficulty
finding alternative suppliers to produce our components on a timely basis. We
have experienced shortages of some of these components in the past, which
delayed related revenue, and we may experience shortages in the future. In
addition, because the majority of our products have a short sales cycle of
between 30 and 90 days, it is difficult to make long term forecasts of our
product needs. As a result, we could experience shortages in supply.

We depend on three contract manufacturers to produce our products. If these
manufacturers are unable to fill our orders on a timely basis, we will likely
be unable to deliver our products to meet customer orders.

   We depend on three contract manufacturers to produce our products. We have
only recently entered into relationships with two of these contract
manufacturers, and we do not have contracts with any of them. If these contract
manufacturers terminate their relationships with us or are unable to fill our
orders on a timely basis, we may be unable to deliver our products to meet our
customers' orders, which could delay or decrease our revenue. Our reliance on
contract manufacturers involves a number of risks, including:

  .  our manufacturers' potential inability to develop high-speed testing and
     manufacturing methods appropriate for our products;

  .  their lack of willingness to devote adequate capacity to produce our
     products;

  .  their inability to maintain continuing relationships with suppliers of
     our components; and

  .  the reduction of our control over delivery schedules and costs of our
     products.

If any of these risks are realized, we could experience an interruption in
supply, which could delay or decrease our revenue.

The average selling prices of our products have been declining, and we may be
unable to achieve the manufacturing cost reductions and improvements required
in order to remain profitable.

   The average selling prices of our products have been declining in recent
years primarily due to an increased percentage of total domestic sales being
made through distributors and value-added resellers, which involve lower prices
than our direct sales. Our prices have also declined due to our increased
international sales, which are generally made through distributors and value-
added resellers and have typically involved greater quantities of lower speed
products with significantly lower prices. This trend is expected to continue
because one of our strategies is to increase the percentage of our total sales
that occur through distributors and value-added resellers and in international
markets. If we do not reduce our production costs and other expenses, we may
not be able to offset this continuing decline and remain profitable. We also
must continue to develop and introduce on a timely basis new systems that can
be sold at higher average selling prices. Failure to develop these new systems
would cause our revenue and gross profits to decline.

   This risk from declining average selling prices may intensify because we
expect that market conditions, particularly falling prices for competing
broadband solutions, will force us to reduce our prices over time. As broadband
wireless access systems become more widely deployed, the price of these
products will decline. Under some circumstances, we may be forced to reduce our
prices even if it causes us to decrease our gross profit or to take a loss on
our products. We may also be unable to reduce sufficiently the cost of our
products to enable them to compete with other broadband access technologies
such as high-speed access lines leased from an incumbent carrier, commonly
known as leased lines. Recently, the prices of these leased lines have declined
significantly in many countries. In order to remain competitive, we need to
design our products so that they can be manufactured with low-cost, automated
manufacturing, assembly and testing techniques. We cannot assure you that we
will be successful in designing our products to allow our contract
manufacturers to use these low-cost, automated techniques. In addition, any
redesign may fail to result in sufficient cost reductions to allow us to
significantly reduce the price of our products or prevent our gross profit from
declining as our prices decline.

                                       7

We expect quarterly revenue and operating results to vary significantly in
future periods, which could cause our stock price to fluctuate.

   Our quarterly revenue and income from operations have varied and are likely
to continue to fluctuate significantly from quarter to quarter. For the four
quarters during the year ended December 31, 1999, our quarterly revenue varied
from $8.6 million to $15.6 million. If our quarterly revenue or income from
operations results fall below the expectations of securities analysts or
investors, the price of our common stock could fall substantially.

   Our quarterly results may fluctuate for many reasons, including the
following:

  .  seasonal factors that may affect capital spending by customers;

  .  the timing and size of orders for our products;

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

  .  our ability to develop, introduce, ship and support new products and
     product enhancements and to manage product transitions;

  .  our ability to obtain sufficient supplies of components for our products
     for which our contract manufacturers have a sole supply source or which
     require a long lead time to produce;

  .  cost pressures from shortages of skilled technical, sales and marketing
     employees, increased product development and other factors;

  .  a failure to achieve cost reductions;

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

  .  delays in deliveries to distributors, value-added resellers and other
     customers; and

  .  manufacturing capacity constraints, which affect our ability to fulfill
     orders.

   We have experienced disruptions in our operations from some of the factors
listed above. For example, seasonal factors have often made our revenue
stronger in the last two quarters of the year. We may experience fluctuations
and other disruptions again in the future.

Our products are highly complex and may contain defects or errors that are
detected only after deployment in complex networks and which, if detected,
could harm our business.

   Our products are highly complex, are designed to be deployed in complex
networks and may contain undetected defects or errors. The occurrence of any
defects or errors could result in: failure to achieve market acceptance and
loss of market share, cancellation of orders, increased service and warranty
costs, diversion of resources, legal actions by our customers and end-users,
increased insurance costs, and other losses to us or to end-users.

   Although our products are tested both during manufacturing and prior to
deployment, they can only be fully tested when deployed in commercial networks.
As a result, end-users may discover defects or errors or experience breakdowns
in their networks after our products have been deployed. If defects or errors
are discovered, we may not be able to successfully correct them and our revenue
could decline. End-users have discovered errors in our products in the past and
may discover errors in our products in the future.

Our future success will depend in part on our ability to protect our
intellectual property rights, and our inability to enforce these rights could
cause us to lose sales and any competitive advantage we have.

   Our success depends to a significant degree upon our ability to protect and
preserve our product and manufacturing process designs and other intellectual
property. However, we may be unable to prevent third parties from using our
technology without our authorization or independently developing technology
that is similar to ours, particularly in those countries where the laws do not
protect our proprietary rights as fully as in the United States. The use of our
technology or similar technology by others could reduce or eliminate any
competitive advantage we have developed, cause us to lose sales or otherwise
harm our business. If it became necessary for us to resort to litigation to
protect these rights, any proceedings could be burdensome and costly

                                       8
<PAGE>

and we may not prevail. We rely on the patent, trademark, copyright and trade
secret laws of the United States to protect our intellectual property rights.

   Although we have several U.S. patents that relate to our Ubiquity point-to-
multipoint technology and several pending U.S. patents that relate to our
Ubiquity technology and our Lynx and Tsunami point-to-point technology, we
generally do not seek patent protection for our technology in the United States
or abroad, and we do not have any international patents or pending patents. Our
competitors may already have applied for patents that, once issued, will
prevail over our patent rights or otherwise limit our ability to sell our
products in the United States or abroad. Our competitors also may attempt to
design around our patents or copy or otherwise obtain and use our proprietary
technology. With respect to our pending patent and trademark applications, we
may not be successful in securing the registration of these items. Our failure
to secure these registrations may limit our ability to protect the intellectual
property rights that these applications were intended to cover. In addition,
even if the pending patents are granted, they may not provide us with any
competitive advantage.

   We currently have several U.S. trademarks that cover our name and logo but
have not yet secured trademarks that cover our product brand names. While we
have applied to register trademarks covering our Lynx and Tsunami brand names,
we do not know whether the U.S. Patent and Trademark Office will grant us
registrations for these trademarks. Although we do sell products
internationally and plan to increase our international sales in the future, to
date, we have not applied for any service marks or trademarks in any foreign
country. Should we decide to apply to register our service marks or trademarks
in a foreign country, there is no guarantee that we will be able to secure
these registrations. Our failure to secure registrations for our pending U.S.
trademark applications, or any foreign applications we decide to file in the
future, may limit our ability to protect the intellectual property rights that
these applications were intended to cover.

   Violations by others of our confidentiality or non-disclosure agreements and
the loss of employees who have specialized knowledge and expertise could harm
our competitive position and cause our revenue and operating results to
decline. To protect our proprietary technology, we limit access to it, treat
portions of it as trade secrets and obtain confidentiality or non-disclosure
agreements from persons with access to it. We cannot be certain, however, that
the parties who have signed these agreements are abiding by these agreements.
If any party to these agreements was to violate their agreement with us and
disclose our proprietary technology to a third party, we may be unable to
prevent the third party from using this information. Because a significant
portion of our proprietary technology consists of specialized knowledge and
technical expertise developed by our employees, we have a program in place
designed to insure that our employees communicate any developments or
discoveries they make with other employees. However, employees may choose to
leave our company before transferring their knowledge and expertise to our
other employees.

Claims that we infringe third-party intellectual property rights could result
in significant expenses and restrictions on our ability to sell our products in
particular markets.

   We have agreed to indemnify some of our customers for intellectual property
infringement claims relating to our products. From time to time, third parties
may assert claims against us or our customers for infringement of their
intellectual property rights. Any infringement claims could result in costly
litigation, divert the efforts of our technical and management personnel, cause
product shipment delays, require us to enter into royalty or licensing
agreements, require us to pay damages, harm our reputation or prevent us from
making or selling certain products. Moreover, if we were to discover that any
of our products violated the intellectual property rights of a third party, we
might be unable to redesign our products to avoid violating their rights or
obtain a license on commercially reasonable terms to use their intellectual
property.

   We currently sell our products internationally and plan to increase our
international sales in the future. Because we do not have any patent or
trademark protection in countries outside of the United States, we may face an
increased risk of infringement claims in international markets where we sell
our products. As a result, we could face an increased risk of third parties
bringing infringement claims against us.

If we fail to manage our growth, our business, financial condition and
prospects could suffer.

   We have expanded our operations in recent years, and we anticipate that
further expansion will be required to address the potential growth in our
customer base and market opportunities. This expansion places a significant
strain on our management, technological, administrative, manufacturing and
financial resources and involves increased expenses for, among other things,
new personnel, additional office space and associated administrative
activities. If our current operations suffer due to the strain on resources
caused by this planned expansion, or if our sales do not correspondingly
increase with the increases in our expenses, our business and prospects for the
future could suffer.

   We recently hired new employees, including a number of key managerial and
operations personnel. Failure to properly train and integrate these new
employees into our business may result in disruptions in our operations. We may
also have difficulties successfully identifying and exploiting existing and
potential market opportunities if our staffing is inadequate.

   In addition, our current and planned expansion may be inadequate to support
our future operations. For example, as we continue to grow our business, we
will need to find additional facilities for expanding our manufacturing
facilities and office space. Office space and other facilities are expensive
and difficult to find in Northern California, where we currently operate. We
may experience difficulties finding suitable locations and these facilities may
only be available at a significant additional expense.

We currently derive a substantial portion of our revenue from a limited number
of distributors. A decrease or loss in business from any of them could harm our
business.

   We generate a significant amount of revenue from three distributors. For the
year ending December 31, 1999, approximately 32% of our revenue was derived
from these three distributors, and approximately 19% of our revenue was derived
from one of these distributors. We do not have long-term contracts with any of
these distributors. The loss of business from any of these distributors or the
delay of significant orders from them, even if only temporary, could reduce or
delay our recognition of revenue, harm our reputation in the industry or reduce
our ability to accurately predict cash flow. Accordingly, unless and until we
diversify and expand our customer base, our future success will depend
significantly on the timing and size of future purchase orders, if any, from a
limited number of distributors.

If our current distributors and value-added resellers terminate their
relationships with us or do not aggressively market our products, and we cannot
identify appropriate replacements, our revenue will decline.

   If our current distributors and value-added resellers terminate their
relationships with us or elect to market, more aggressively than our products,
alternative broadband access solutions or products of our competitors, our
revenue will decline. We have no agreements for minimum purchase commitments
from our distributors or value-added resellers and our relationships with most
of them are non-exclusive. Many of our distributors also market alternative
broadband access solutions or a competitor's similar products. We cannot
control the amount and timing of resources that our distributors and value-
added resellers devote to our products. In the event of any problem with our
current distributors and value-added resellers, we may not be able to find a
replacement with the appropriate customer base for our products or that will be
willing to enter into a relationship with us on terms acceptable to us. If and
to the extent we experience an increase in the future in the percentage of our
sales made as a result of our relationships with systems integrators, we will
face the same risks with them as described for distributors and value-added
resellers.

If we fail to identify appropriate acquisition opportunities or to integrate
the operations of acquired companies with our own operations, or if acquired
companies fail to perform as expected, our business could be adversely
affected.

   One component of our business strategy is to expand our presence in new and
existing markets by acquiring additional businesses that would complement our
current products, enhance our technological capabilities or offer growth
opportunities. We may not identify or complete these acquisitions in a timely

                                       10
<PAGE>

manner, on a cost effective basis or at all, and we may not realize the
benefits of any acquisition. Any of these factors may adversely affect our
business by diverting management attention and resources from our existing
business.

   We have limited experience in acquisition activities and may have to devote
substantial time and resources in order to identify acquisition opportunities,
which may not be successful, or if successful, to complete acquisitions and
integrate them into our existing operations. In addition, in the event of any
future acquisitions, we could issue stock that would dilute our current
stockholders' percentage ownership, or incur debt or assume unknown or
contingent liabilities that could affect our profitability. Moreover,
acquisitions may involve investment related or other charges and amortization
of acquired technology, goodwill and other intangible assets, any of which
could adversely affect our results of operations. We also face risks of
entering markets in which we have no or limited prior experience.

   We recently acquired Ubiquity Communication, Inc., which develops point-to-
multipoint technology that we will use in our Ubiquity products, which are
currently under development. We cannot assure you that we will succeed in
integrating Ubiquity Communication's operations, or the operations of any other
companies we may acquire, into our existing operations. If any of the following
events occur, our business could be adversely affected:

  .  loss of key personnel with specialized technology and product knowledge;

  .  failure to integrate operations, technologies, products and personnel;

  .  failure of one or more acquired companies to perform as expected;

  .  unexpected costs or liabilities relating to our acquisitions are
     incurred; or

  .  failure of expected operating efficiencies from acquisitions to
     materialize.

If a natural disaster occurs in Northern California, where our headquarters and
our contract manufacturers are located, our business could be disrupted.

   Our corporate headquarters and those of our contract manufacturers are
located in Northern California. Northern California historically has been
vulnerable to natural disasters such as earthquakes, fires and floods, which at
times have disrupted the local economy and posed physical risks to our and our
manufacturers' properties. We and two of our contract manufacturers do not have
alternative sites at which we or they could operate in the event of a natural
disaster. As a result, if a natural disaster were to occur, our business could
suffer.

Risks Related to Our Industry

Our business will be harmed if the demand for wireless services in general and
broadband wireless access systems in particular does not continue to grow.

   The wireless telecommunications industry has recently experienced a high
rate of growth both in the United States and internationally. Our success is
dependent on the continued trend toward wireless telecommunications and data
communications services. If the rate of growth slows and service providers
reduce their capital investments in wireless infrastructure or fail to expand
into new geographic markets, our business may be harmed. In addition, broadband
wireless access solutions are unproven in the marketplace and some of the
technologies, such as wireless point-to-multipoint technology, have only been
commercially introduced in the last few years. If broadband wireless access
technology turns out to be unsuitable for widespread commercial deployment, it
is unlikely we could generate enough sales to sustain profitability. Many
factors will influence the success or failure of broadband wireless access
technology, including:

  .  its capacity to handle growing demands for faster transmission of
     increasing amounts of data, voice and video;

  .  its cost-effectiveness and performance compared to other forms of
     broadband access, whose prices and performance continue to improve;

                                       11
<PAGE>

  .  its reliability and security;

  .  whether the products can be manufactured in sufficient volume;

  .  its suitability for a sufficient number of geographic regions;

  .  the availability of sufficient frequencies for network service providers
     to deploy products at commercially reasonable rates;

  .  the availability of sufficient site locations for network service
     providers to install products at commercially reasonable rates; and

  .  safety and environmental concerns about broadband wireless
     transmissions.

In addition, factors adversely affecting the demand for wireless services
generally, such as allegations of health risks associated with the use of
wireless technologies, could slow or delay the deployment of wireless networks.
These factors, as well as future legislation, legal decisions and regulation
relating to the wireless telecommunications industry may slow or delay the
deployment of wireless networks, which would harm our business and operating
results.

If we do not develop new products and new product features that keep pace with
technological advances and respond to customer requirements in a timely manner,
customers may not buy our products.

   If new industry standards emerge that we do not anticipate or adapt to, our
products could be rendered obsolete and our business could be harmed. Our
revenue is derived primarily from sales of our various product lines. We expect
that revenue from product sales will continue to be our primary revenue source.
If we do not develop new products or enhancements on a timely basis, or if any
of our new products or product features do not achieve market acceptance,
customers may not purchase our products. A number of factors, including design
or manufacturing difficulties, could delay or prevent us from developing,
introducing or marketing new products or enhancements. In addition, our
competitors may introduce new products before we do and achieve a competitive
advantage by being among the first in our markets. Because adaptation of our
products may be costly, our operating results could suffer as we make the
necessary adjustments to our products. We have experienced and may in the
future experience delays in our product development, introduction and
marketing, any of which could result in a loss of revenue.

Broadband wireless access solutions have some disadvantages and limitations as
compared to other alternative broadband access solutions that may prevent
widespread adoption, which could hurt our profitability and prospects.

   Broadband wireless access solutions, including point-to-point and point-to-
multipoint systems, compete with other high-speed access solutions such as
digital subscriber lines, cable modem technology, fiber optic cable and other
high-speed wire line and satellite technologies. If the market for our point-
to-point and point-to-multipoint solutions fails to develop or develops more
slowly than we expect due to this competition, our sales opportunities and
profitability would be harmed. Many of the alternative technologies can take
advantage of existing installed infrastructure and are generally accepted to be
reliable and secure. As a result, they have already achieved significantly
greater market acceptance and penetration than broadband point-to-point and
point-to-multipoint broadband wireless access technologies. Moreover, current
point-to-point and point-to-multipoint broadband wireless access technologies
have inherent technical limitations that may inhibit their widespread adoption
in many areas, including the need for line-of-sight installation and, in the
case of operating frequencies above 11 GHz, reduced communication distance in
bad weather.

   We expect point-to-point and point-to-multipoint broadband wireless access
technologies to face increasing competitive pressures from both current and
future alternative technologies. In light of these factors, many service
providers may be reluctant to invest heavily in broadband wireless access
solutions.

The broadband wireless access industry is intensely competitive, and our
failure to compete effectively could hurt our sales and reduce our margins.

   The market for broadband wireless access equipment in general and the
markets for point-to-point and point-to-multipoint technologies specifically
are rapidly evolving and highly competitive. We expect to face increasing
competitive pressures from both current and future competitors in the markets
we serve, which could hurt our sales and reduce our profitability due to
pricing pressures. A number of companies already have begun selling point-to-
multipoint products and may have a competitive advantage over us because there
is often a significant advantage to being among the first to market. Several
large telecommunications equipment suppliers, including Alcatel, Cisco Systems,
Inc., Ericsson Business Networks AB, Lucent Technologies Inc. and Nortel
Networks Corporation, as well as a number of smaller companies, including
Adaptive Broadband Corp., P-Com, Inc., Proxim Inc., Netro Corporation and Wi-
Lan Corp., have developed or are developing products that compete with one or
more of our products. Many of our competitors are substantially larger than we
are and have significantly greater financial, sales, marketing, distribution,
technical, manufacturing and other resources. These competitors may make
strategic acquisitions or establish cooperative relationships among themselves
or with third parties to increase their ability to gain market share rapidly,
which would hurt our business.

Many service providers that use broadband wireless access technologies are
emerging companies with unproven business models.

   Many of our new service provider customers are emerging companies with
limited access to capital, few customers and developing networks. If these
service providers fail or we lose them as customers, our revenues would
decline. Because the broadband wireless access market is intensely competitive,
service providers typically are forced to reduce their monthly access charges
to attract and retain end-users. Any reduction in monthly access charges
decreases the amount of capital available for service providers to invest in
additional broadband wireless infrastructure. As a result, these service
providers may become under-capitalized and may not be able to remain in
business for a substantial period of time.

Our business would be harmed if we fail to attract, hire, and retain qualified
personnel.

   Competition for personnel in our industry and in Northern California where
we are located is intense, and we may not be successful in attracting and
retaining qualified personnel. The loss of the services of any key personnel or
our inability to hire new personnel with the requisite skills could restrict
our ability to develop new products or enhance existing products in a timely
manner, sell products to our customers or manage our business effectively.
There are only a limited number of people in the job market with the requisite
skills, particularly people with radio frequency technology expertise. We may
not be able to hire or retain qualified personnel if we are unable to offer
competitive salaries and benefits in the Northern California labor market. In
addition, as a public company we may find it more difficult to attract
personnel and we may have to increase compensation. We are also dependent on
the continued contributions of our principal sales, engineering and management
personnel, many of whom would be difficult to replace.

Broadband wireless products could malfunction due to radio interference or
adverse weather conditions which could adversely affect our financial and
competitive position.

   Many of our customers provide telecommunications services in large
metropolitan areas where wireless traffic is heavy. If multiple wireless
systems are operating in these service areas concurrently with our products,
the radio frequencies on which our products operate could become saturated,
resulting in signal interference. This interference could cause the quality or
availability of our customers' transmissions to decrease or could cause our
products to fail, which would lead to:

  .  service delays and interruptions;

  .  a loss or delay in market acceptance and sales of our products;

                                       13
<PAGE>

  .  cancellation of orders;

  .  diversion of development resources;

  .  injury to our reputation; and

  .  increased maintenance and warranty costs.

Interference caused by severe weather conditions could cause similar failures.
The ability of our products to provide our customers with high quality and
reliable transmissions at all times and under a variety of adverse conditions
is key to our success.

Line-of-sight restrictions inherent in broadband wireless access products may
limit deployment and could have an adverse effect on our sales.

   Broadband wireless access products require a direct line-of-sight, which may
limit the ability of service providers to deploy them in a cost-effective
manner and could harm our sales. Because of line-of-sight limitations, service
providers often install broadband wireless access equipment on the rooftops of
buildings and on other tall structures. Before undertaking these installations,
service providers must generally secure roof rights from the owners of each
building or other structure on which the equipment is to be installed. The
inability to easily and cost-effectively obtain roof rights may deter customers
from choosing to install broadband wireless access equipment, which could have
an adverse effect on our sales.

Risks Related to the Offering and Ownership of Our Common Stock

The market price of our common stock is likely to be volatile and you may not
be able to resell your shares at or above the initial public offering price.

   Previously, there has not been any public market for our common stock, and
we cannot predict the extent to which investors' interest will lead to a liquid
trading market. The initial public offering price for the shares will be
determined by negotiations with us and the representative of the underwriters
and may not be indicative of the prices that will prevail in the trading
market. The market price of our common stock could fluctuate significantly, in
which case you may not be able to resell your shares at or above the initial
public offering price. Fluctuations may occur in response to the risk factors
listed in this prospectus and for many other reasons, including:

  .  our financial performance or the performance of our competitors and
     similar companies;

  .  changes in estimates of our performance or recommendations by securities
     analysts;

  .  failure to meet financial projections for each fiscal quarter;

  .  technological innovations or other trends in our industry;

  .  the introduction of new products by us or our competitors;

  .  the arrival or departure of key personnel;

  .  acquisitions, strategic alliances or joint ventures involving us or our
     competitors; and

  .  market conditions in the industry, the financial markets and the economy
     as a whole.

   In addition, the stock market in general and technology stocks in particular
have recently experienced extreme price and volume fluctuations. These
fluctuations are often unrelated to the operating performance of particular
companies. These broad market fluctuations may cause declines in the market
price of our common stock. When the market price of a company's common stock
drops significantly, stockholders often institute

                                       14
<PAGE>

securities class action lawsuits against the company. A lawsuit against us
could cause us to incur substantial costs and could divert the time and
attention of our management and other resources.

Control by our existing stockholders will limit your ability to influence the
outcome of matters requiring stockholder approval and could discourage
potential acquisitions of our company by third parties.

   We anticipate that our executive officers and directors and the entities
affiliated with them, together with the current holders of more than 5% of our
equity, including Ripplewood Partners, L.P. and its affiliates, will own
approximately   % of our outstanding common stock following the completion of
this offering. This concentration of ownership could have the effect of
delaying or preventing a change of control of our company or otherwise
discourage a potential acquiror from obtaining control of us, which could have
an adverse effect on the market price of our common stock or prevent you from
realizing a premium over the market price of your shares. Our current
stockholders will be able to influence significantly all matters requiring
approval by our stockholders, including the election of our board of directors
and the approval of mergers or other business combination transactions.

Future sales of common stock by our existing stockholders could cause our stock
price to decline.

   If our current stockholders sell substantial amounts of common stock in the
public market, including shares that we may issue upon the exercise of
outstanding options and warrants, the market price of our common stock could
decline. The perception among investors that these sales may occur could
produce the same effect. After the offering, shares owned by our current
stockholders and holders of options and warrants to acquire our common stock,
assuming the exercise of all options and warrants, including those of our
directors and executive officers, are expected to constitute approximately   %
of our total outstanding common stock, or   % if the underwriters' over-
allotment option is exercised in full. Following the expiration of a 180-day
lock-up period to which substantially all of the shares held by current
stockholders will be subject, our shares of common stock may become available
in the public market.

   After the offering, the holders of approximately 46,239,351 shares of our
common stock, including shares issuable upon the exercise of outstanding
warrants, will have rights, subject to some conditions, to require us to file
registration statements covering their shares or to include their shares in
registration statements that we may file. By exercising these registration
rights and selling a large number of shares, these holders could cause the
price of our common stock to decline. Furthermore, if we were to include their
shares in a registration statement, those sales could impair our ability to
raise needed capital by depressing the price at which we could sell our common
stock. See "Shares Eligible for Future Sale" for a more detailed description of
the shares that will be available for future sales upon completion of the
offering.

We have anti-takeover defenses in our amended and restated certificate of
incorporation and bylaws, and Delaware law contains provisions that could delay
or prevent an acquisition of our company, which could depress our stock price
or lessen any premium over market price that an acquiror might pay.

   Our amended and restated certificate of incorporation and bylaws and
Delaware law contain provisions that might enable our management to resist a
proposed takeover of our company. These provisions could discourage, delay or
prevent a change of control of our company or an acquisition of our company at
a price that stockholders may find attractive. These provisions may also
discourage proxy contests and make it more difficult for our stockholders to
elect directors and take other corporate actions. The existence of these
provisions could limit the price that investors might be willing to pay in the
future for shares of our common stock. See "Description of Capital Stock--Anti-
Takeover Provisions in Delaware Law and Our Amended and Restated Certificate of
Incorporation" for a more detailed description of these provisions.

You will suffer immediate and substantial dilution because the net tangible
book value of shares purchased in the offering will be substantially lower than
the initial public offering price.

   The net tangible book value per share of our common stock, adjusted to
reflect the net proceeds we receive from the offering, will be substantially
below the initial public offering price. You will therefore incur immediate and
substantial dilution of $   per share at the initial public offering price of
$   per share, the mid-point of the initial offering price range per share set
forth on the cover of this prospectus. As a result, if we are liquidated, you
may not receive the full amount of your investment.

Our stock option plan may cause us to incur additional expense and cause you to
suffer further dilution.

   Our outstanding options under our stock option plan have a weighted average
exercise price of $.54 per share. We will incur substantial deferred stock
compensation related to the difference between the exercise price per share
under the stock option plan and the deemed fair value of the shares at the time
the options were granted. We will recognize a compensation expense over the
vesting period of three years for such options. Furthermore, the exercise of
the options will cause you to suffer further dilution.

               SPECIAL NOTE REGARDING FORWARD LOOKING STATEMENTS

   In various places in this prospectus we use statements which constitute
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995. These statements relate to future events or our
future plans, objectives, and expectation and financial performance. In some
cases, you can identify forward-looking statements by terminology such as may,
will, should, expects, intends, plans, anticipates, believes, estimates,
predicts, potential, continue, or the negative of these terms or other similar
expressions.

   We caution prospective purchasers of our common stock that forward-looking
statements are not guarantees of future performance and that they may involve
risks and uncertainties. Actual events may differ from those in the forward-
looking statements as a result of various factors. Many of these factors are
beyond our control and our actual results could differ materially from those
discussed in these statements. The "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Result of Operations" and "Business"
sections of this prospectus identify important factors that could cause these
differences. If any of these factors were to occur, then the results in these
statements could be significantly different.

   Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. We are under no duty to update any of
the forward-looking statements after the date of this prospectus to conform
these statements to actual results, except pursuant to any disclosure
requirements and reporting obligations under applicable securities laws.

                                USE OF PROCEEDS

   We expect to receive net proceeds of approximately $   million from the sale
of     shares of common stock in the offering, or approximately $   million
from the sale of     shares of common stock if the underwriters exercise their
over-allotment option in full. These estimates reflect an initial public
offering price of $   per share, the mid-point of the initial offering price
range per share set forth on the cover of this prospectus and the deduction of
the underwriting discount and commissions and estimated offering expenses
payable by us.

   We expect to use a portion of the net proceeds from the offering to repay
outstanding indebtedness. We expect to use approximately $2.0 million of the
net proceeds from the offering to repay outstanding indebtedness under our
revolving credit facility which expires on November 1, 2002. The interest rate
of the revolving credit loans to be repaid was 8.8% as of April 19, 2000. We
have used the borrowings under the revolving credit facility to finance our
working capital needs. We expect to use approximately $10.0 million of the net
proceeds to prepay a term loan which matures on November 1, 2002, referred to
as Term Loan A. In addition, we expect to use approximately $12.0 million of
the net proceeds to prepay a term loan which matures on November 1, 2004,
referred to as Term Loan B. The interest rate of Term Loan A and Term Loan B
was 8.8% and 11.3%, respectively, as of April 19, 2000. Term Loan A and Term
Loan B are required to be repaid in full as a result of the offering. We used
the borrowings under Term Loan A and Term Loan B to effect the recapitalization
of Western Multiplex which occurred on November 1, 1999. For a description of
the recapitalization transaction, see "Material Relationships and Related
Transactions."

   We intend to use the remainder of the net proceeds of the offering primarily
for general corporate purposes, including working capital, expansion of our
engineering organization, product development programs, sales and marketing
capabilities, and general administrative functions and capital expenditures. We
may also use a portion of the net proceeds to acquire complementary businesses,
products and technologies or to establish joint ventures that we believe will
complement our current or future business. However, we have no specific plans,
agreements or commitments and are not currently engaged in any negotiations for
any acquisition or joint venture.

   We have not identified the specific use of the net proceeds due to the
flexible nature of our planning process. The amounts that we actually expend
for general corporate and other purposes will vary significantly depending on a
number of factors, including future sales growth and the amount of cash we
generate from operations, if any. As a result, we will retain broad discretion
in the allocation of and reserve the right to change the use of net proceeds of
the offering. Because of this discretion, we may use the net proceeds of the
offering in ways with which you disagree. Pending the use of the proceeds
described above, we will invest the net proceeds in short-term, interest-
bearing, investment-grade securities.

                                DIVIDEND POLICY

   In 1997, we declared and paid $11.6 million of dividends to GTI Acquisition
Corp., our parent company at that time. We do not expect to pay any dividends
on our common stock for the foreseeable future. We currently intend to retain
any future earnings to finance future growth. Any future determination to pay
dividends will be at the discretion of our board of directors and will depend
on our financial condition, results of operations, capital requirements and
other factors the board of directors deems relevant. As a result, you will need
to sell your shares of common stock to realize a return on your investment, and
you may not be able to sell your shares at or above the price you paid for
them.

                                    DILUTION

   Dilution is the amount by which the initial public offering price paid by
the purchasers of common shares in the offering exceeds the net tangible book
value per common share after the offering. Net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the aggregate number of common shares outstanding on the date net
tangible book value is determined.

   As of December 31, 1999, we had a historical net tangible book value
(deficit) of $(7,400,000) or $(.19) per share of common stock.

   Our pro forma net tangible book value at December 31, 1999 has been
determined by giving effect to the issuance of 3,869,351 shares of our Class B
common stock to WMC Holding Corp. from January 1, 2000 through March 31, 2000
and the acquisition of Ubiquity Communication, Inc., which occurred after
December 31, 1999, as follows:

</TABLE>

   Pro forma net tangible book value per share is determined by using
42,562,123 common shares outstanding on a pro forma basis and before giving
effect to the offering. Common shares outstanding on a pro forma basis is the
sum determined by giving effect to the following:

  .  the 38,000,000 common shares outstanding at December 31, 1999;

  .  the issuance of 3,869,351 shares of our Class B common stock to WMC
     Holding Corp.; and

  .  the 692,772 common shares issued in connection with the acquisition of
     Ubiquity Communication, Inc.

   Pro forma as adjusted net tangible book value per share is determined by
using     common shares outstanding, which is the sum of:

  .  the common shares outstanding on a pro forma basis; and

  .  the     common shares to be sold in this offering.

   The pro forma net tangible book value (deficit) of our shares at December
31, 1999 was approximately $(.14) per common share. After giving effect to the
receipt of the net proceeds of the offering based upon an initial public
offering price of $   per share, the mid-point of the initial price range set
forth on the cover of this prospectus, our pro forma as adjusted net tangible
book value at December 31, 1999 would have been $   million, or $   per common
share. These transactions represent an immediate increase in net tangible book
value of $   per common share to existing holders of common shares and an
immediate dilution of $   per common share to new public investors. The
following table illustrates this per common share dilution:

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

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

Overview

   We were founded in 1979 in Sunnyvale, California as a vendor of radio
components and related services. In 1992, we changed our strategy, became a
designer and manufacturer of broadband wireless systems and launched our Lynx
broadband wireless systems. These point-to-point systems are primarily used by
wireless operators to connect their base stations to other base stations and to
existing wire line networks. During the past eight years, we have introduced a
number of Lynx products, including our Lynx DS-3, currently the industry's
fastest license-exempt wireless system. In 1999, we introduced our Tsunami
point-to-point broadband wireless systems, which primarily enable service
providers, businesses and other enterprises to expand or establish private
networks by bridging Internet traffic among multiple facilities. Based on our
core technologies and the technology acquired through our purchase of Ubiquity
Communication, Inc. in March 2000, we are currently developing point-to-
multipoint systems that will enable service providers, businesses and other
enterprises to connect multiple facilities within a geographic area to a
central hub.

   Revenue. We primarily generate revenue from the sale of our Lynx and Tsunami
systems. Our Ubiquity systems are still under development and we expect to
begin offering these systems for sale in 2001. We also generate a small
percentage of our revenue from the sale of services and parts and rentals of
our systems. We recognize revenue from the sale of our systems and parts when
all the following conditions are met: the system or part has been shipped, we
have the right to invoice the customer, the collection of the receivable is
probable, and we have no significant obligations remaining. We generally
recognize service and rental revenue over the period that the services are
performed or the rental is provided.

   The majority of our direct sales are currently to wireless operators, and we
believe that the majority of the products that we sell through distributors and
value-added resellers are eventually sold to wireless operators.

   We sell our products worldwide to service providers, businesses and other
enterprises directly through our sales force and indirectly through
distributors and value-added resellers. Our sales force focuses on key
strategic accounts and also develops relationships with end-users that purchase
through distributors and value-added resellers. Distributors sell our products,
and value-added resellers not only sell our products, but also assist end-users
in network design, installation and testing. We also market our products
through strategic relationships we have with systems integrators, which design
and install networks that incorporate our systems. Any significant decline in
direct sales to end-users or in sales to our distributors or value-added
resellers, or the loss of any of our distributors, or value-added resellers
could materially adversely affect our revenue.

   In 1999, we sold our products to 480 customers in 34 countries. In 1999,
international sales accounted for approximately 23% of our total sales. We
expect international sales to increase in the future. Currently, all of our
sales are denominated in U.S. dollars. Accordingly, we are not exposed to
currency exchange risks other than the risk that exchange rate fluctuations may
make our products more expensive for customers outside the United States and,
as a result, could decrease international sales. In addition, we face risks
inherent in conducting global business. These risks include extended collection
time for receivables, reduced ability to enforce obligations and reduced
protection for our intellectual property.

                                       23
<PAGE>

   As we have increased sales through our distributors and value-added
resellers, we have experienced a decline in the average selling price of our
products. This is because the prices of the products that we sell indirectly
through distributors and value-added resellers are lower than the prices of the
products we sell directly through our sales force to end-users. We have also
lowered our prices for older products as we introduce additional products that
provide faster data rates. These newer products have higher prices than our
older products. Our international sales also have lower average selling prices
when compared to our United States and Canadian sales. This is primarily due to
our reliance on distributors and value-added resellers for international sales,
and also because our lower speed products, with significantly lower prices, are
being sold in larger quantities internationally than domestically. As indirect
sales and sales in our international markets increase, we expect that our
average selling prices will further decrease.

   Cost of revenue. Cost of revenue consists primarily of outsourced
manufacturing costs, component costs, labor and overhead costs, costs of
acquiring finished parts from original equipment manufacturers, customer
service and accrued warranty costs. We currently outsource the majority of our
manufacturing and supply chain management to a limited number of independent
contract manufacturers, who obtain components for our products from suppliers.
Accordingly, a significant portion of our cost of revenue consists of payments
to these contract manufacturers and component suppliers. The remainder of our
cost of revenue is related to our in-house manufacturing operations, which
consist primarily of quality control, final assembly, testing and product
integration. We expect to realize lower per unit product costs as we continue
to outsource more of our in-house manufacturing. However, we cannot assure you
when or if cost reductions will occur. The failure to achieve these cost
reductions could materially adversely affect our gross margins and operating
results.

   Gross profit. Our gross profit is affected by both the average selling
prices of our systems and our cost of revenue. Historically, decreases in our
average selling prices have generally been offset by reductions in our per unit
product cost. We cannot assure you, however, that we will achieve any
reductions in per unit product cost in the future or that any reductions will
offset a reduction in our average selling prices.

   Research and development. Research and development expenses consist
primarily of salaries and related personnel expenses, prototype development
expenses, consultant fees and allocated overhead related to the design,
development, testing and enhancement of our products and underlying
technologies. We expense all research and development expenses as incurred. We
expect to increase our research and development expenses as we continue to
develop new products and improve our core technologies. In particular, we
expect research and development expenses to increase in connection with our
acquisition of Ubiquity Communication Inc. and our development of point-to-
multipoint broadband wireless access systems.

   Sales and marketing. Sales and marketing expenses consist of salaries,
commissions and related expenses for personnel engaged in sales, product
marketing, sales support functions, advertising, trade show and other
promotional expenses and allocated overhead. We intend to increase our sales
and marketing expenditures as we add sales and marketing personnel, increase
the number of distributors and value-added resellers that sell our products and
increase marketing programs. In particular, we expect sales and marketing
expenses to increase as we substantially expand our sales operations to support
and develop leads for our distributors and value-added resellers.

   General and administrative. General and administrative expenses consist
primarily of salaries and related expenses for executive, finance and
administrative personnel, professional fees, other general corporate expenses
and allocated overhead. We expect general and administrative expenses to
increase as we add personnel, increase spending on our information systems and
incur additional costs related to the growth of our business and operation as a
public company.

   Stock option programs. We have implemented stock option programs for
employees and members of our board of directors to attract and retain business
and technical personnel. During the first quarter of 2000, we will record
deferred stock compensation for the difference between the exercise price and
the deemed fair value

                                       24
<PAGE>

of our common stock on the date the stock options were granted. This amount is
included as a reduction of stockholders' equity and is being amortized by
charges to operations over the vesting period. The amortization expense relates
to options awarded to employees in all operating expense categories.

Acquisition of Ubiquity Communication Inc.

   On March 24, 2000, we acquired Ubiquity Communication, Inc., located in
Petaluma, California. Through the acquisition, we acquired technology that will
enable us to develop our point-to-multipoint systems. At the time of the
acquisition, Ubiquity Communication had seven employees, including six
engineers. We issued 692,772 shares of our common stock to the former owners of
Ubiquity Communication and reserved 137,727 shares for issuance upon the
exercise of the Ubiquity options we assumed. We accounted for the transaction
using the purchase method of accounting. Accordingly, we have recorded
purchased intangibles and goodwill of $6.0 million to be amortized over a three
year period. We intend to treat the acquisition of Ubiquity Communication as a
tax-free reorganization.

Recapitalization

   On November 1, 1999, Ripplewood Partners, L.P. and affiliates acquired 94.6%
of our capital stock from Glenayre Technologies, Inc. through a wholly-owned
subsidiary, WMC Holding Corp., in a transaction accounted for as a
recapitalization. Prior to the recapitalization, we were an indirect wholly-
owned subsidiary of Glenayre Technologies, Inc., which had previously acquired
us in 1995. As part of Glenayre's acquisition of us, Glenayre recognized $21.6
million of goodwill, amortized over a 30-year useful life. This goodwill amount
is reflected on our historical financial statements. As of December 31, 1999,
there was $18.6 million to be amortized over the remaining 25 year term.

   We intend to treat the recapitalization as an asset acquisition for federal
income tax purposes. As a result, we recorded a deferred tax asset in the
amount of $3.9 million which will offset future tax liabilities during the next
15 years, assuming that we have sufficient income to realize the full benefit
of this deduction.

Comparison of Year Ended December 31, 1999 and 1998

   Revenue. Revenue increased 36.0% from $32.9 million in 1998 to $44.8 million
in 1999. The increase in revenue was primarily attributable to increased sales
through distributors and value-added resellers. Revenue from sales outside of
the United States and Canada also increased 107.3% from $5.1 million 1998 to
$10.4 million in 1999. In 1999, Somera Communications Inc., one of our
distributors, accounted for 19.2% of revenue. No other customer accounted for
more than 10% of total revenue in 1998 or 1999.

   Cost of revenue. Cost of revenue increased 26.9% from $17.7 million in 1998
to $22.5 million in 1999. This increase in cost of revenue was primarily
attributable to increased sales. As a percentage of revenue, cost of revenue
decreased from 53.8% in 1998 to 50.2% in 1999, primarily due to lower cost of
components and increased reliance on outsourced manufacturing, which has lower
costs relative to our in-house manufacturing.

   Research and development. Research and development expenses increased 21.8%
from $4.9 million in 1998 to $5.9 million in 1999. The increase in research and
development expenses was primarily attributable to the cost of increased
personnel and prototype spending for the development of new products and
enhancements to existing products. As a percentage of revenue, research and
development expenses decreased from 14.8% in 1998 to 13.2% in 1999.

   Sales and marketing. Sales and marketing expenses increased 32.7% from $4.6
million in 1998 to $6.1 million in 1999. The increase in sales and marketing
expenses was primarily attributable to increases in sales personnel and
increased advertising, tradeshow and public relations expenses for our
international sales and marketing activities. As a percentage of revenue, sales
and marketing expenses decreased from 14.0% in 1998 to 13.7% in 1999.

   General and administrative. General and administrative expenses increased
37.2% from $1.4 million in 1998 to $2.0 million in 1999. The increase in
general and administrative expenses was primarily attributable to increased
information systems personnel, audit fees and the fee paid to Ripplewood for
management and administrative services. As a percentage of revenue, general and
administrative expenses increased from 4.3% in 1998 to 4.4% in 1999.

   Other income (expenses), net. Other expense increased from $24,000 in 1998
to $3.4 million in 1999. This increase in expense was primarily attributable to
transaction costs of $3.1 million associated with the recapitalization and
interest related to the loans incurred in November 1999 as part of the
recapitalization.

   Income tax provision. The income tax provision increased from $1.4 million
in 1998 to $2.9 million in 1999. Our effective tax rate increased from 38.6% in
1998 to 69.8% in 1999. The effective tax rate increase was primarily due to the
expenses we incurred as part of the recapitalization, which are not tax
deductible.

Comparison of Year Ended December 31, 1998 and 1997

   Revenue. Revenue increased 2.5% from $32.1 million in 1997 to $32.9 million
in 1998. The relative low growth rate during 1998 was primarily attributable to
low growth rates in the wireless broadband access market in 1998. Sales outside
of the United States and Canada increased 40.3% from $3.6 million in 1997 to
$5.1 million in 1998.

   Cost of revenue. Cost of revenue increased 10.4% from $16.0 million in 1997
to $17.7 million in 1998. The increase in cost of revenue was primarily
attributable to an increase in customer service and unusable components. As a
percentage of revenue, cost of revenue increased from 50.0% in 1997 to 53.8% in
1998.

<PAGE>

   Research and development. Research and development expenses increased 18.7%
from $4.1 million in 1997 to $4.9 million in 1998. The increase in research and
development expenses was primarily attributable to increased personnel
contributing to our development efforts. As a percentage of revenue, research
and development expenses increased from 12.8% in 1997 to 14.8% in 1998.

   Sales and marketing. Sales and marketing expenses increased 21.2% from $3.8
million in 1997 to $4.6 million in 1998. The increase in sales and marketing
expenses was primarily attributable to increased hiring and training of
international and domestic sales personnel. As a percentage of revenue, sales
and marketing expenses increased from 11.9% in 1997 to 14.0% for 1998.

   General and administrative. General and administrative expenses remained
about the same at $1.4 million in 1997 and 1998.

   Other income (expense), net. Other income decreased from $1.0 million in
1997 to other expense of $24,000 in 1998. The decrease was primarily
attributable to non-receipt of interest income from Glenayre, our parent
company at the time, relating to intercompany indebtedness.

   Income tax provision. The income tax provision decreased by 53.8% from $2.9
million in 1997 to $1.4 million in 1998. Our effective tax rate decreased from
41.8% in 1997 to 38.6% in 1998 primarily due to decreases in the permanent
differences between book and taxable income.

   Our quarterly revenue and income from operations results have varied and are
likely to continue to fluctuate significantly from quarter to quarter. For the
four quarters ended December 31, 1999, our quarterly revenues varied from $8.6
million to $15.6 million. If our quarterly revenue or income from operations
results fall below the expectations of security analysts or investors, the
price of our common stock could fall substantially.

   Our quarterly results may fluctuate for many reasons, including the
following:

  .  seasonal factors that may affect capital spending by customers;

  .  the timing of sales of our products;

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

  .  our ability to develop, introduce, ship and support new products and
     product enhancements and to manage product transitions;

  .  our ability to obtain sufficient supplies of components for our products
     for which our contract manufacturers have a sole supply source or
     require a long lead time to produce;

  .  cost pressures from shortages of skilled technical, sales and marketing
     employees, increased product development and other factors;

  .  a failure to achieve cost reductions;

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

  .  delays in deliveries to distributors, value-added resellers and other
     customers; and.

  .  manufacturing capacity constraints, which affect our ability to fulfill
     orders.

   We have experienced disruptions in our operations from some of the factors
listed above and may experience them again. In addition, we are dependent on
decisions by service providers, businesses and other enterprises to build
wireless networks. These decisions are in turn dependent upon the success and
expected demand for the services offered by those service providers, businesses
and other enterprises.

   We plan to increase significantly our operating expenses to fund greater
levels of research and development, expand our sales and marketing operations,
broaden our customer support capabilities and develop new relationships with
distributors and value-added resellers. We also plan to expand our general and
administrative functions to address the increasing size of our business and the
increasing reporting and other administrative demands that will result from
being a separately traded public company. Our operating expenses are largely
based on anticipated revenue trends, and a high percentage of our expenses are
and will continue to be fixed in the short term. As a result, any delay in
generating or recognizing revenue could cause significant variations in our
operating results from quarter to quarter and could result in substantial
operating losses.

   Due to the above factors, we believe that quarter-to-quarter comparisons of
our operating results are not a good indication of our future performance. It
is likely that in some future quarters, our operating results may be below the
expectations of public market analysts and investors. In this event, the price
of our common stock may fall.

Liquidity and Capital Resources

   We have financed our operations and working capital requirements primarily
through cash generated by our business and bank financing.

   Cash decreased by 55.0% from $3.1 million in 1997 to $1.4 million in 1998.
Cash increased by 38.9% from $1.4 million in 1998 to $1.9 million in 1999.
Operating activities generated $8.2 million in cash in 1997, $2.2 million in
cash in 1998 and $6.4 million in cash in 1999.


                                       28
<PAGE>

   Depreciation decreased by 14.1% from $789,000 in 1997 to $678,000 in 1998.
Depreciation decreased by 13.4% from $678,000 in 1998 to $587,000 in 1999.
Fixed assets are recorded at cost and depreciated over the estimated useful
lives of the assets, which range from three to seven years. Leasehold
improvements are amortized over the shorter of their useful life or the life of
the lease.

   Cash used in investing activities decreased 8.1% from $717,000 in 1997 to
$659,000 in 1998. Investing activities increased 84.8% from $659,000 in 1998 to
$1.2 million in 1999. Our capital spending budget for 2000 is $1.6 million.

   Net cash used in financing activities was $6.8 million in 1997, $3.3 million
in 1998, and $4.6 million in 1999. We paid $6.9 million in distributions to
Glenayre in 1997, $3.3 million in distributions to Glenayre in 1998 and $3.8
million in distributions to Glenayre in 1999. Glenayre did not provide any
financing for our company during the time it owned us. In 1999, in connection
with the recapitalization, we redeemed 42,000,000 shares of our Class B common
stock from Glenayre for $21.0 million and incurred $3.1 in recapitalization
costs.

   At December 31, 1999, we had $1.9 million of cash. On November 1, 1999, in
connection with the recapitalization, we entered into a credit agreement with
Credit Suisse First Boston, as agent, in the aggregate amount of $32 million.
This credit agreement consists of the following three components: (1) a $10
million revolving credit facility, (2) a $10 million term loan, referred to as
Term Loan A and (3) a $12 million term loan, referred to as Term Loan B. The
borrowings under the revolving credit facility accrue interest at LIBOR plus
2.5% or prime plus 1.5%, as periodically elected by us. The revolving credit
facility expires on November 1, 2002. Term Loan A has an interest rate of LIBOR
plus 2.5% or prime plus 1.5%, as periodically elected by us, and a maturity
date of November 1, 2002. Term Loan B has an interest rate of LIBOR plus 5.0%
or prime plus 4.0%, as periodically elected by us, and a maturity date of
November 1, 2004. At December 31, 1999, there were $2.0 million of revolving
credit borrowings and $22.0 million of term loan borrowings outstanding under
the credit agreement. We may prepay the term loans at any time upon adequate
notice to the lenders. All principal amounts outstanding under the term loans
must be prepaid in the event of an initial public offering by us. We will be
prepaying the term loans with the net proceeds from the offering. See "Use of
Proceeds" and note 5 to our financial statements for more information.

   We believe that the net proceeds from this offering together with our
existing cash and cash equivalents and our available borrowings will be
sufficient to finance our working capital and capital expenditure requirements
for at least the next 12 months. Our management intends to invest any cash in
excess of current operating requirements in short-term, interest-bearing
investment-grade securities. Our future capital requirements will depend upon
many factors, including management of working capital, the success of
marketing, sales and distribution efforts, the timing of research and product
development efforts and expansion of our marketing efforts.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement No.
133, Accounting for Derivative Instruments and Hedging Activities (SFAS No.
133), which establishes accounting and reporting standards for derivative
instruments and hedging activities. The statement requires recognition of all
derivatives at fair value in the financial statements. FASB Statement No. 137,
Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133, an amendment of FASB Statement No.
133, defers implementation of SFAS No. 133 until fiscal years beginning after
June 15, 2000. We do not have any derivative instruments or hedging activities.

Disclosures About Market Risk

   As of December 31, 1999, we had cash of $1.9 million. Substantially all of
this amount was in non-interest bearing accounts and had no risk to interest
rate fluctuations. We currently have debt of $24.0 million, and the interest
charges for those loans vary quarterly with LIBOR. As a result, an increase in
interest rates would result in increased interest costs to us for that debt. We
will be prepaying $22.0 million of term loans and $2.0 million of revolving
credit loans with the net proceeds of the offering. Accordingly, our interest
expense will decrease.

   We do not own any material equity investments. As a result, we do not
currently have any direct equity price risk.

   Currently, all sales to international customers are denominated in U.S.
dollars and, accordingly, we are not currently exposed to foreign currency
exchange rate risks other than the risk that conversion to U.S. dollars at a
high cost may cause some customers to search for a lower priced competitive
product.

Seasonality

   Historically, our revenues have been stronger in the last two quarters of
the fiscal year. This shift may primarily be attributed to the budgetary
constraints of the customers in our industry and weather conditions which make
an outdoor installation more difficult during the winter. However, going
forward, we believe the impact of seasonal fluctuations on our business will
decrease because demand for our products is increasing at a rate that outpaces
any budget restrictions our customers may have. Moreover, our expansion into
international markets may minimize the impact that weather conditions may have
on our overall sales.

                                    BUSINESS

Overview

   We are a global provider of broadband, or high-speed, wireless access
systems that enable service providers, businesses and other enterprises to
deliver data, voice and video services. We believe our fixed wireless systems
address the growing need of our customers and end-users to rapidly and cost
effectively deploy high-speed communication networks. During the last eight
years, we have developed proprietary technologies that have enabled us to
introduce what we believe are some of the fastest, longest range and most
reliable broadband wireless systems available, including our Lynx DS-3,
currently the industry's fastest license-exempt wireless system.

   Our systems operate in both the licensed and license-exempt portions of the
radio frequency spectrum. Our Lynx and Tsunami systems enable direct, or point-
to-point, fixed wireless communication between two locations. Our Lynx systems
are primarily used by wireless operators to connect their base stations to
other base stations and to existing wire line networks. Our Tsunami systems are
primarily used by service providers, businesses and other enterprises to expand
or establish private networks carrying Internet traffic among multiple
facilities. Our Ubiquity point-to-multipoint systems, which are currently under
development, will enable service providers, businesses and other enterprises to
connect multiple facilities within a geographic area to a central hub.

   We serve the global broadband wireless access market by selling our systems
to service providers, businesses and other enterprises directly through our
sales force and indirectly through distributors, value-added resellers and
systems integrators. In 1999, we sold our systems to 480 customers in 34
countries.

Industry Background

 Development of the Wireless Industry

   The wireless communications industry provides fixed and mobile data, voice
and video communications services. Wireless communications technologies have
rapidly developed in recent years. International Data Corporation estimated
that the number of wireless subscribers will increase from 427 million in 1999
to 1.1 billion in 2003, representing a compound annual growth rate of 27%.

   Initially, wireless technology was primarily used to provide voice services.
However, as the speed and range of wireless access systems increases and the
cost declines, users are increasingly looking to wireless communications to
augment or substitute for traditional data, voice and video wire line
communications. This is particularly true in less densely populated areas and
in developing countries where traditional wire line systems are often expensive
and time consuming to install or unavailable.

 Increased Demand for Broadband Communications

   Over the past decade, the amount of broadband data transmitted across
telecommunications networks has grown significantly due to the increased use of
the Internet and bandwidth-intensive applications. Bandwidth, which refers to
the transmission capacity of a communication channel, is generally measured in
bits per second and the more bits per second, the higher the bandwidth.

   Consumers, businesses and other enterprises, such as schools, hospitals and
government agencies, are expanding their use of the Internet to increase
efficiency, improve relationships and foster better communication through
applications such as electronic commerce, e-mail, supply chain management, web
hosting and global marketing. As users increasingly rely on higher-bandwidth
applications for business and personal use, they demand cost-effective and
reliable broadband access, which is often unavailable or inadequate over the
existing wire line infrastructure. In addition, as broadband access becomes
less expensive and more widely available, the use of bandwidth-intensive
applications by businesses and consumers is expected to increase further.

                                       31
<PAGE>

   Users of mobile wireless services are also expanding their use of high
bandwidth applications. As wireless operators are increasingly providing data
services to these users, the demand for network capacity is increasing.
Wireless operators are addressing this demand by increasing the number and
density of base stations within their networks, as well as increasing the
capacity of their existing base stations. In addition, wireless operators
providing service at higher frequencies can require up to four times as many
base stations as those operating at lower frequencies in order to reach the
same coverage area. As a result, Allied Business Intelligence, Inc. predicts
that the number of wireless base stations deployed will grow from approximately
1.1 million in 1999 to approximately 2.1 million in 2003.

   In addition, the deregulation of the global telecommunications industry is
increasing demand among service providers for broadband access technologies.
This deregulation has enabled a large number of service providers to provide
local network access that was historically offered only by a single, often
monopolistic, provider in a geographical region. As these service providers
enter new markets, they seek to differentiate themselves by offering high-speed
Internet access and integrated data, voice and video services. Because
traditional wire line infrastructure is often expensive and time consuming to
install or unavailable, service providers are increasingly searching for
broadband access technologies that are more cost-effective and can be more
rapidly deployed.

 Limitations of Traditional Access Solutions

   Today, the fastest components of the Internet infrastructure are a series of
fiber optic cables capable of transmitting large volumes of data, voice and
video at high speeds. This part of the Internet infrastructure is generally
referred to as the fiber backbone or the fiber loop. Service providers,
businesses, other enterprises and consumers have not been able to take full
advantage of this high-speed technology because of the limitations of
traditional communications networks.

   Traditional communications networks connect end-users to the fiber backbone
using a wire line network that links various segments. The connection between
the end-user and the service provider's central office, which is the facility
where network traffic is aggregated and routed to other locations, is known as
the last mile. Last mile connections typically occur over telephone lines using
analog modems, which are not capable of transmitting large amounts of data,
voice and video as quickly as developing broadband solutions. As a result, end-
users who connect to the network backbone using analog modems may wait several
minutes to access a graphic-intensive web site and several hours to send or
download large files. In addition, some applications such as video conferencing
may be completely unavailable using traditional telecommunications networks.
This last mile bottleneck impedes the ability of service providers to satisfy
their customers' demands for high-speed data, voice and video services.

   The last mile segment represents the most costly portion of traditional wire
line networks because of the large number of end-users that must be connected
to the central office and sporadic traffic patterns with peaks and lows. These
sporadic traffic patterns require that the network connections be built to
handle peak capacity even though this capacity will be underutilized during low
traffic periods.

   The other segment in a traditional communications network connects the
central office of a service provider to the fiber backbone. This segment is
known as the backhaul segment and requires greater bandwidth and transmission
speeds than the last mile because the central office must aggregate the data,
voice and video from multiple end-users before sending it to the fiber
backbone. Traditional wire line solutions for the backhaul segment of a
traditional wire line network are often expensive and time-consuming to install
or unavailable.

   Traditional access solutions also have limitations for wireless operators
seeking to expand the capacity of their cellular and personal communication
service networks to provide data services by increasing the number of their
base stations. Although base stations could be connected to the central office
by wire line technologies, the cost and time required to deploy wire line
technologies generally have made these technologies unattractive to wireless
operators.

 Broadband Access Technologies Other Than Wireless

   The following are the primary technologies, other than wireless
technologies, that are currently being offered as broadband access solutions:

   Leased line service. Telephone companies and other carriers have deployed
dedicated, copper-based digital phone lines to satisfy demand for broadband
communications. Leased lines commonly used in the United States are known as T1
lines and are capable of transmitting data at 1.5 megabits per second. Leased
lines commonly used internationally are known as E1 lines and are capable of
transmitting data at 2.0 megabits per second. Historically, single or multiple
T1 and E1 lines have been sufficient to meet the broadband access needs of end-
users. However, as Internet usage continues to expand, current T1 and E1 lines
may be unable to meet the bandwidth needs of end-users because the speed with
which they transmit data may be too slow. Because it is often expensive and
time consuming for emerging service providers to deploy their own wire line
networks, they typically lease lines from existing carriers. As a result, these
service providers do not have control over their network facilities.

   Cable modem technology. Cable service providers connect to homes using
coaxial cable, which has greater transmission capacity than the copper-based
digital phone lines traditionally used by telephone companies. However, because
cable networks are generally designed to send information to the end-user, they
provide asymmetrical services, which means that the transmission speed is
higher from the network to the end-user than from the end-user to the network.
Moreover, the data transmission rates available to each end-user in a service
area decrease as total usage in the area increases. Upgrades to symmetrical
services, which provide equal transmission rates between the end-user and the
network, are often expensive. In addition, cable modem technology is focused on
addressing the needs of the residential market and is often unavailable to
businesses and other enterprises.

   Satellite service. Satellite solutions also enable only asymmetrical two-way
access services. These solutions use broadcast satellite technology for high-
speed transmissions from the service provider to end-users but use slower wire
line connections to transmit data from the end-users to the service provider.
In addition, like the limitations of cable modem services, the available data
transmission rates to each end-user in a satellite service area decreases as
total usage increases.

   Digital subscriber line. Digital subscriber line technology, commonly known
as DSL, increases the speed of data transmission over a service provider's
existing copper-wire network. Most deployments of DSL technology, however,
offer either high-speed asymmetrical transmission speeds or slower symmetrical
transmission speeds. DSL service is often not an attractive last mile access
solution because its performance is limited by the quality of available copper
wires and the maximum distance between the end-user and the service provider.

   Fiber optic cable. Fiber optic cable offers the highest data transmission
rate of any access solution, including wireless technologies, but it is often
expensive and time-consuming to install or unavailable. Installing a fiber
optic cable often requires digging up city streets, and it can take several
months to obtain the necessary permits and complete installation. As a result,
fiber optic cable technology is typically deployed as a broadband access
solution for large businesses in densely populated areas that can spread the
high installation costs over many users.

 Broadband Wireless Technology

   Service providers, businesses and other enterprises are increasingly
utilizing point-to-point and point-to-multipoint broadband wireless solutions
within their networks. Point-to-point and point-to-multipoint broadband
wireless access technology can address many of the limitations of traditional
wire line solutions and can also be used in conjunction with wire line
solutions.

                                       33
<PAGE>

   Point-to-point wireless systems. Point-to-point wireless systems are used
for connecting two sites that demand very high speed transmission rates over
long distances. They can be installed in a variety of configurations, but tend
to be installed as dedicated links that enable the symmetrical transmission of
high-speed data. Wireless operators use point-to-point systems for the backhaul
segments of their cellular and personal communication service networks.
Emerging service providers primarily use point-to-point systems for the
backhaul segments of their networks but also deploy these systems to solve the
last mile bottleneck problems of end-users with high bandwidth requirements. In
addition, business and other enterprises use point-to-point systems to extend
or create private networks.

   Point-to-multipoint wireless systems. Point-to-multipoint wireless systems
enable the symmetrical transmission of data between a centrally located hub and
multiple end-user locations. These systems can be used to connect multiple
sites that do not require the dedicated high speed connections available in
point-to-point systems and to cover geographic areas with a concentrated number
of end-users. Because multiple remote units share a common hub in a point-to-
multipoint system, service providers, businesses and other enterprises can
provide a last mile bottleneck solution and add additional end-users to their
networks at lower incremental costs than with traditional point-to-point
systems.

   Service providers, businesses and other enterprises can rapidly deploy
broadband wireless networks because they do not have to depend on wire line
infrastructure. In addition, low installation costs make the deployment of
broadband wireless access systems a cost-effective solution for service
providers, businesses and other enterprises that need to create or extend their
networks for end-users across multiple locations. Wireless technology may be
limited, however, because it requires line-of-sight, and depending upon the
frequency, can be impacted by severe weather conditions.

   Domestic and international authorities regulate the allocation of the radio
frequency spectrum. Although regulatory authorities require service providers,
business and other enterprises to obtain licenses to operate wireless
communications equipment in some portions of the frequency spectrum, other
portions of the spectrum are exempt from licensing requirements. By installing
equipment which operates in the license-exempt portions of the spectrum,
service providers, businesses and other enterprises can avoid the often lengthy
regulatory approval process and reduce the time and costs required to install
broadband wireless access systems.

   We believe the rapid development of the wireless communications industry and
the increased demand for broadband communication has created an opportunity for
wireless technology to become the preferred solution for addressing the
limitations of wire line access technologies. Today's service providers,
businesses and other enterprises are looking to wireless technology as an
attractive option for broadband access.

The Western Multiplex Solution

   We believe that our broadband wireless systems address the growing need for
bandwidth where alternative solutions are either too expensive to deploy in a
timely fashion or unavailable. Our systems are used in a variety of
applications in different markets, including:

  .  Wireless operator infrastructure. Our systems enable cellular and
     personal communication service providers to connect their base stations
     to other base stations and to existing wire line networks. These
     connections comprise the backhaul segment of their networks.

  .  Fiber extension. Our systems enable service providers to extend the
     reach of the fiber backbone with products that combine the high
     transmission speeds and reliability of fiber optic cable with the
     flexibility, cost effectiveness and rapid deployment of wireless
     technologies.

  .  Campus and other private networks. Our systems enable enterprises with
     multiple facilities, including those located in a campus environment, to
     connect their facilities to expand or establish private networks.

                                       34

  .  Last mile access. Our systems connect end-users with a service
     provider's central office, providing high-speed last mile access.

   The key benefits of our solution include:

   Rapid deployment. Service providers, businesses and other enterprises can
rapidly deploy our licensed and license-exempt systems to establish new, or
expand existing, network infrastructures. Competing technologies such as
digital phone lines and fiber optic cable generally take longer to deploy than
our broadband wireless access systems. In addition, our license-exempt systems
do not require frequency coordination and regulatory approval. As a result,
service providers, businesses and other enterprises can avoid many of the time
consuming processes typically required in installing licensed wireless
technologies.

   Telecommunications grade reliability and availability of service. We have
developed proprietary error correction algorithms, fault tolerant systems and
comprehensive network management software designed to enable our Lynx and
Tsunami systems to match or exceed fiber network reliability standards. These
wireless systems are designed to provide 99.999% reliability, or less than five
minutes of down time per year. In contrast, digital phone lines typically
provide 99.7% reliability, which translates into over 500 minutes of down time
per year. As a result, our systems enable service providers, businesses and
other enterprises to provide end-users with telecommunications grade
reliability and availability, which is equal to or better than that offered by
most alternative broadband access solutions.

   High-speed and long distance connections. We have used our engineering
expertise and proprietary radio frequency and digital signal processing
technologies to design systems that offer an attractive combination of high-
speed transmission rates and long-range coverage. During the past eight years,
we have introduced what we believe are some of the fastest and longest-range
wireless systems available, including our Lynx DS-3, currently the industry's
fastest license-exempt system, and our Lynx 4T1, which we believe is the
longest-range license-exempt system in the market. This combination of high-
speed data transmission and long-range coverage enables service providers,
businesses and other enterprises to extend the reach of their fiber optic cable
and other wire line networks.

   Cost-effective solution. Because our proprietary technology enables our
systems to transmit over longer distances than competing product designs,
service providers, businesses and other enterprises require fewer units to
cover a specified area. As a result, they are able to reduce both their initial
and incremental capital expenditures for network deployment and are able to
achieve a higher return on their invested capital.

   Fully integrated end-to-end solution. We offer a broad range of systems that
enable service providers, businesses and other enterprises to create complete
broadband wireless networks that connect end-users to the fiber backbone. Our
point-to-point systems are primarily used within the backhaul segments of
networks and also provide last mile access to large businesses. Our Ubiquity
point-to-multipoint systems, which are under development, will primarily be
used to provide last mile access to residential users and small businesses. Our
systems use similar radio frequency technology, digital signal processing and
network management software. We believe this design commonality offers service
providers, businesses and other enterprises higher end-to-end performance,
lower equipment costs, and lower training and maintenance costs.

Strategy

   Our objective is to be a leading global provider of broadband wireless
access systems. Our strategy to accomplish this objective is to:

   Capitalize on our technology expertise to rapidly introduce new
products. Over the last eight years, we have developed several core
technologies that form the basis of our current product lines and which we
intend to use in our future product development. Our dedicated team of
engineers has multi-disciplinary technical capabilities, including radio
frequency technology, digital signal processing and system software
development.

                                       35
<PAGE>

We believe integrating these capabilities is highly complex, and we intend to
continue to take advantage of our technology expertise to introduce product
enhancements and new products in a rapid and cost effective manner. For
example, we are currently developing a point-to-point broadband wireless system
capable of transmitting data at speeds in excess of 180 megabits per second and
point-to-multipoint systems which will easily integrate with our existing
point-to-point systems.

   Utilize existing customer relationships to expand into new market
segments. In 1999, we sold our systems to 480 customers in 34 countries. Our
customers include AT&T Wireless Group, Bell Atlantic Corporation, GTE
Corporation, Motorola, Inc., Nextel Communications, Inc., Pacific Bell and
Voicestream Wireless Corporation. We intend to build upon our relationships
with current customers as they continue to expand their networks and enter new
market segments, such as fiber extension, campus and other private networks and
last mile access. We believe that we will be well-positioned to provide our
current customers with broadband wireless access solutions in their new
markets.

   Increase our presence in international markets. According to International
Data Corporation, in 1999 the number of international wireless subscribers
represented approximately 81% of total worldwide wireless subscribers. While
our products are currently sold and approved for use in 30 countries, we intend
to increase our presence in these countries and further expand into new
international markets where broadband wire line access is currently too
expensive or unavailable. In particular, we believe there is a substantial
opportunity for our licensed products in countries where government authorities
have granted or have indicated that they intend to grant broadband wireless
licenses. Additionally, as governmental authorities make license-exempt
spectrum available, we believe our license-exempt systems will be well-
positioned for rapid deployment in these international markets. We will
continue to expand our presence worldwide by expanding our international sales
and marketing efforts, obtaining regulatory approval for deploying our systems
in new international markets, increasing our total product offerings in both
existing and new international markets and establishing strategic alliances and
partnerships.

   Aggressively market through distributors, value-added resellers and systems
integrators. We have established relationships with key distributors, value-
added resellers and systems integrators such as Avant Telecoms Inc., CSI
Computer Specialists, Inc., Datatec Ltd, Hutton Communication, Inc., Somera
Communications Inc., Tessco Technologies Incorporated, Westcon Inc. and
Wireless Facilities, Inc., to market and sell our systems. To further
accelerate our growth, we intend to build upon our existing relationships and
establish new relationships with distributors, value-added resellers and
systems integrators that we believe have strong relationships with potential
customers for our Lynx, Tsunami and Ubiquity systems. Our marketing group is
currently developing materials and programs such as training courses to assist
our distributors, value-added resellers and systems integrators in penetrating
these markets.

   Expand through acquisitions. We intend to pursue acquisitions of
complementary businesses, technologies, products or services to expand our
presence in the broadband wireless access market. On March 24, 2000, we
acquired Ubiquity Communication, Inc., a Petaluma, California-based company.
Through the acquisition, we acquired technology that we will integrate with our
core technologies to develop our point-to-multipoint Ubiquity systems.

Products

   We have three product lines: our existing Lynx and Tsunami product lines and
our Ubiquity product line, which is under development. Our Lynx and Tsunami
products enable direct, or point-to-point, communication between two locations.
We believe these products are among the fastest and longest-range broadband
wireless systems available on the market. Our Ubiquity point-to-multipoint
products are being designed primarily to enable service providers, businesses
and other enterprises to connect multiple facilities within a geographic area
to a central hub.

                                       36
<PAGE>

   We design our systems generally to use common features, components and
software, which we believe results in greater reliability and reduced design
and manufacturing costs. In addition, we believe our current systems offer and
our products under development will offer users a cost effective broadband
access solution because the common design allows for reduced training and easy
integration into their networks.

   Our products feature various industry standard interfaces and operate at
different transmission speeds and radio frequencies. An interface is a physical
link connecting two or more pieces of equipment together.

   Lynx products. Our point-to-point Lynx products are primarily used by
wireless operators to connect their base stations to other base stations and to
existing wire line networks. These connections comprise the backhaul segments
of their networks. In addition, these products are also used to establish
campus and private networks and to provide fiber extension and last mile
access. Our Lynx products are offered in a variety of frequencies, ranging from
2.4 GHz to 11 GHz, which includes both licensed and license-exempt spectrum,
and in a variety of data transmission speeds, ranging from 56 Kbps per second
to 45 Mbps per second. Our Lynx products can transmit and receive the maximum
data capacity in both directions simultaneously, a feature commonly known as
full duplex. Our products have a compact, fully-integrated design and a built-
in network management system. They can be linked together within a network and
managed with simple network management protocol, or SNMP, software. Our Lynx
products also include a separate control and diagnostic channel which remotely
monitors the system's status and performance without reducing its carrying
capacity.

   We are currently developing additional Lynx products, some of which will be
capable of operating at speeds exceeding 180 megabits per second. These
products under development will be additional solutions for fiber extension and
last mile access.

   Tsunami products. Our point-to-point Tsunami products primarily enable
service providers, business and other enterprises to expand or establish
private networks by bridging Internet traffic among multiple facilities.

                                       37
<PAGE>

In addition, these products are also used to provide fiber extension and last
mile access. Tsunami products are currently offered in a variety of
frequencies, ranging from 2.4 GHz to 23 GHz, and in a variety of data
transmission speeds, ranging from 2 Mbps per second to 45 Mbps per second. Like
our Lynx products, our Tsunami products offer features including full duplex
transmission, fully-integrated design and a separate control and diagnostic
channel. In addition, our higher capacity Tsunami systems also include an
additional T1 or E1 connection without reducing the carrying capacity of the
system. The additional T1 or E1 connection is a standard telecommunications
interface that is not based on Internet Protocol and is typically used for
voice.

   We are currently developing Tsunami products that will operate at speeds
exceeding 100 megabits per second. These products under development will be
additional solutions for fiber extension, last mile access and campus and
private networks.

 Ubiquity Products

   We are currently developing our point-to-multipoint Ubiquity systems to
enable service providers, businesses and other enterprises to address the last
mile bottleneck. We are designing these systems to enable service providers to
cost-effectively connect end-users to a central hub. Businesses and other
enterprises may also use these systems to cost-effectively connect multiple
facilities within their private networks.

   Our Ubiquity system will be deployed in a hub and spoke configuration
consisting of a single central hub and equipment located at each end-user's
premises. The central hub will wirelessly connect to the remote customer
premises equipment. It will also prioritize transmission and allocate slots of
time to each end-user based on a system called time division duplexing. We
believe our time division duplexing technology will provide a more efficient
use of capacity than most alternative technologies to accommodate the peaks and
lows of traffic between the end-user and the central hub. The central hub will
operate in a range of frequencies, in various geographic configurations and
will be capable of supporting hundreds of units of customer premises equipment.
The hub unit will also be able to connect to the central office of a service
provider using our point-to-point technology. The customer premises equipment
will transmit and receive data between the end-user and the central hub at
various transmission speeds and frequencies.

   Prototypes of a point-to-multipoint product that use the Ubiquity technology
and are similar to the products we plan to introduce have been completed under
a contract with the U.S. Navy.

Technology

   Over the last eight years, we have developed a number of core technologies
that form the basis of our current product offerings and which will also be
used in our future product development. Our primary areas of technology
expertise are radio frequency technology, digital signal processing and system
software development.

   Radio frequency technology. Microwave and millimeter-wave technology are the
technologies used to wirelessly transmit data, voice and video. Microwave
technology uses radio frequencies ranging from 1 GHz up to 20 GHz, and
millimeter-wave technology uses frequencies above 20 GHz. We believe we are one
of the few wireless equipment manufacturers in the industry that has internally
developed fully integrated microwave circuit board designs. We believe having
these design capabilities provides us with higher performance, lower production
costs, shorter development cycles and the ability to customize our products so
that they can easily be integrated with our existing products and with the
networks of our various customers and end-users.

   Digital signal processing technology. Our products use proprietary digital
signal processing technologies and designs that we developed specifically for
use in wireless systems. We believe these proprietary technologies have enabled
us to introduce a number of high-speed wireless products that may not have been
possible to produce with generic digital signal processing chip sets that are
commercially available. Because our development cycles are not dependent on an
external supplier, we believe we can develop flexible,

                                       38
<PAGE>

innovative products more quickly than our competitors who do not have this in-
house capability. We are currently using our technological expertise in digital
signal processing to develop next generation, high-speed wireless systems
designed to operate at speeds over 180 megabits per second.

   System software. Our systems use SNMP-based software that enables remote
monitoring and control and facilitates the integration and compatibility of our
products with larger communications networks. In addition, we have patented
software for bandwidth allocation, which we believe will allow our Ubiquity
products to use bandwidth more efficiently and to operate at higher speeds than
other point-to-multipoint systems.

Sales and Marketing

   We sell our products worldwide to service providers, businesses and other
enterprises directly through our sales force and indirectly through
distributors and value-added resellers. We focus our marketing efforts on
supporting our direct sales force, distributors, value-added resellers and
systems integrators. We also seek to stimulate market demand by increasing
brand awareness and educating potential customers about the advantages of using
our products.

   Direct sales. Our direct sales force is responsible for both domestic and
international sales and is primarily based in the United States. As of March
31, 2000, our direct sales force consisted of 15 sales representatives. Of
these sales representatives, nine covered the United States and Canada and six
covered international sales, primarily in Latin America, Europe, Asia and the
Caribbean.

   In the United States and Canada, our sales force focuses on key strategic
accounts such as service providers, businesses and other enterprises and also
develops relationships with end-users that purchase through distributors and
value-added resellers. Outside the United States and Canada, sales are
generally made through distributors or value-added resellers. Our sales force,
however, develops direct relationships with end-users either independently, in
which case the sales representative then brings in the distributor or value-
added reseller to complete the sale, or together with the distributors or
value-added resellers through the relationships they have developed with the
end-users.

   Distributor and value-added reseller relationships. We have established
relationships with large national and international distributors, local and
specialized distributors and value-added resellers. The distributors sell our
products, and the value-added resellers not only sell our products, but also
assist their customers in network design, installation and testing. In some
cases, both distributors and value-added resellers also assist their customers
with financing, maintenance and the purchase of ancillary equipment necessary
for installation of a wireless network. Our primary distributor relationships
include Somera Communications Inc., Tessco Technologies Incorporated and
Westcon Inc., most of whom distribute our products nationwide. Our primary
value-added reseller relationships include Avant Telecoms Inc., Hutton
Communication, Inc. and Solunet, Inc. Hutton Communication, Inc. and Solunet
are domestic value-added resellers and Avant is one of the largest value-added
resellers of wireless equipment in Taiwan. We are currently exploring
opportunities to begin selling directly to original equipment manufacturers.

   Systems integrators. We also market our products through strategic
relationships we have with systems integrators, which design and install
networks that incorporate our systems. Systems integrators typically do not
purchase and resell equipment to their customers. Instead they typically
recommend equipment to their customers for use in the systems they design and
install. Although we currently have relationships with a number of systems
integrators, we are expanding our focus in this area by establishing new
relationships with additional systems integrators.

Customer Service

   We are committed to providing our customers with high levels of service and
support. We provide training, technical assistance and customer support on the
installation, management, use and testing of our

                                       39
<PAGE>

products. We also provide a 24-month warranty for our systems and offer both
in-warranty and out-of-warranty repair services. Our repair center is staffed
with technicians who work directly with our quality assurance team to identify
potential problems and repair equipment. In addition, we have a number of
flexible hardware and software maintenance and support programs available for
our products.

Customers and End-Users

   We have a globally diversified base of customers and end-users consisting of
service providers, businesses and other enterprises. In 1999, we sold our
systems to 480 customers in 34 countries.

   Our top ten wireless operator end-users include:

     Alltel Corp.                             KG Telecommunications Co., Ltd.


     AT&T Wireless Group                      Nextel Communications, Inc.

     GTE Corporation                          Western Wireless Corporation

   Our top ten business and other enterprise end-users include:

     Burlington Northern Railroad Co.         Motorola, Inc.


     Canadian National Railway Company        ThinRoute Technologies Inc.


     Education Networks of America            U.S. Coast Guard


     El Paso Energy Corporation               Westower Corp.


     Florida Power & Light Co.                Williams Communication Group,
                                           Inc.

   For the year ended December 31, 1999, sales to Somera Communications, one of
our distributors, represented 19% of our sales.

Research and Development

   Our research and development efforts are focused on improving the
functionality and performance of our existing products as well as developing
new products to meet the changing needs of our diverse base of customers and
end-users. We are currently pursuing the following research and development
initiatives:

  .  developing our point-to-multipoint Ubiquity systems;

  .  adapting our products to additional frequencies and interfaces;

  .  developing higher speed products;

  .  increasing the performance of our digital signal processing technology;
     and

  .  designing our products for low-cost, outsourced manufacturing, assembly
     and testing.

   Our dedicated team of engineers has multi-disciplinary technical
capabilities, including radio frequency technology, digital signal processing
development and system software development. We devote a substantial portion of
our resources to developing new products, enhancing existing products,
expanding and improving our core wireless technologies and strengthening our
technological expertise. Over the last eight years, we have made and expect to
continue to make, significant investments in research and development. We
invested approximately $5.9 million, $4.9 million and $4.1 million in research
and development activities in 1999, 1998, and 1997, respectively.

                                       40

Manufacturing

   Our ISO 9001 certified manufacturing operation, based in our Sunnyvale,
California facility, consists primarily of pilot production, product assembly
and product testing. Our strategy is to outsource manufacturing and procurement
of component parts to manufacturers with the expertise and ability to achieve
the cost reductions associated with volume manufacturing and to respond quickly
to orders, while maintaining our quality standards. This allows us to focus our
internal resources on developing new products. We rely on two contract
manufacturers to produce our printed circuit boards and one contract
manufacturer for limited printed circuit board testing. We complete the final
assembly and testing of our products at our Sunnyvale facility. We are
currently evaluating alternatives for outsourcing a portion of our final
assembly and test functions to our contract manufacturers.

   We depend on single source suppliers for several of our components. Most of
these components are purchased by our contract manufacturers. We carry
additional inventory of these components, as do our contract manufacturers, but
we may have manufacturing shortages if our sales increase more than we expect.
We have experienced in the past and may in the future experience difficulties
in obtaining various components due to capacity constraints among suppliers in
our industry which are experiencing high levels of demand.

Competition

   The market for broadband wireless access systems is rapidly evolving, highly
competitive and subject to rapid technological change. Because we develop a
variety of products for several different markets, we have a broad range of
competitors. Competition for one or more of our systems include products
manufactured or marketed by a number of large communication equipment
suppliers, including Alcatel, Cisco Systems, Inc., Ericsson Business Networks
AB, Lucent Technologies Inc. and Nortel Networks Corporation, as well as by a
number of smaller companies, including Adaptive Broadband Corp., P-com, Inc.,
Proxim Inc., Netro Corporation and Wi-Lan Corp. Many of our competitors are
substantially larger than we are and have significantly greater financial,
sales, marketing, distribution, technical, manufacturing and other resources.
In addition, our competitors may provide financing to their customers.
Companies in the communications industry which are currently not selling
broadband wireless access products, as well as our current competitors, may
make strategic acquisitions or establish cooperative relationships among each
other or with third parties to enter this market or to increase their ability
to gain market share rapidly. We expect to face increasing competitive
pressures from both current and future competitors in the markets we serve.

   We believe our competitive position in the point-to-point segment of the
market is strong, primarily because of our history since 1992 in servicing this
market and because we have introduced some of the first high-speed wireless
license-exempt systems. We have not yet developed a competitive position in the
point-to-multipoint segment of the market because we have not yet finished
developing these products. A number of other companies have begun commercially
selling point-to-multipoint systems, and these companies may have a competitive
advantage because they were the first to market this type of product. We
believe, however, that we will be able to successfully compete by using our
relationships with our existing customers to sell our new point-to-multipoint
systems, which can be integrated with our other systems, and because we believe
our point-to-multipoint systems may have features our competitors' systems do
not have.

   Technological developments and consolidation within the broadband wireless
access equipment industry result in frequent changes to our group of
competitors. The principal competitive factors in our market include:

  .  product features and reliability;

  .  the ability to be among the first to introduce new products;

  .  price;

  .  brand recognition;

  .  relationships with distributors, value-added resellers, systems
     integrators and service providers;

                                       41
<PAGE>

  .  the ability to integrate various products into a single network; and

  .  customer service and technical support.

   Broadband wireless access solutions also compete with other high-speed
solutions such as cable modem technologies, satellite technologies, digital
subscriber lines and fiber optic cables. Many of these alternative technologies
can take advantage of existing installed infrastructure and have achieved
significantly greater market acceptance and penetration than broadband wireless
access technologies. We expect to face increasing competitive pressures from
both current and future technologies in the broadband access market.

Intellectual Property

   Our success depends on the preservation and protection of our product and
manufacturing process designs and other proprietary technology. We use a
variety of intellectual property in the development and manufacturing of our
products, but do not believe that any of our intellectual property is
individually critical to our current operations. Taken as a whole, however, we
believe our intellectual property rights are significant.

   We currently have five U.S. patents, each of which relate to our Ubiquity
point-to-multipoint systems, which are still under development. We also have
one pending U.S. patent application that pertains to the Ubiquity system and
two pending U.S. patent applications that pertain to our license-exempt Lynx
and Tsunami systems. We have four U.S. trademarks, which cover variations of
our name and logo, and have several pending U.S. trademark applications, which
cover the names of some of our more important product lines. Because, to date,
we have sold our products primarily in the United States, we have not yet
applied to register any of our intellectual property in any foreign countries.
However, we intend to file foreign patent and trademark applications in the
future, in instances where we consider a particular trademark or aspect of our
technology important enough to justify the added expense of pursuing the
filings.

   In addition to our registered intellectual property, we also use proprietary
technology in our business. This technology includes internally developed
proprietary error correction algorithms, fault tolerant systems and
comprehensive network management software. A significant portion of this
technology consists of specialized knowledge and technical expertise that has
been developed over time by our employees. In order to maintain the
confidential nature of this technology, we have chosen to protect it by
generally limiting access to it, treating portions of it as trade secrets and
obtaining confidentiality or non-disclosure agreements from persons who are
given access to it. All of our employees have signed our standard
confidentiality agreement, which prohibits them from disclosing our
confidential information, technology developments and business practices, as
well as any confidential information entrusted to us by other parties.
Similarly, all of the consultants who have been given access to our
confidential information or proprietary technology have signed an agreement
prohibiting them from disclosing that information and technology to others.

   The protections we have secured for our intellectual property rights, and
our ability to enforce those rights, may be inadequate to prevent others from
using our technology or independently developing technology that is
substantially similar to our own. The use of our technology or similar
technology by others could reduce or eliminate any competitive advantage we
have developed, cause us to lose sales and otherwise harm our business.
Moreover, to the extent that we secure intellectual property rights in foreign
countries, the laws of these countries may not afford us the same level of
protection we receive in the United States. If we resort to legal proceedings
to enforce our intellectual property rights, or are forced to defend our rights
in a suit filed by a third party, these proceedings could be burdensome and
costly, regardless of whether we ultimately prevail.

Government Regulation

   Our products must conform to a variety of regulatory requirements and
protocols. In order for our products to be used in some jurisdictions,
regulatory approval and in some cases, specific country compliance testing, may
be required. For example, all products designed for use in the United States
must be certified by the

                                       42
<PAGE>

Federal Communications Commission before we can ship them. The delays inherent
in this regulatory approval process may cause the rescheduling, postponement or
cancellation of the installation of our products by our customers which, in
turn, may significantly reduce our sales.

   The failure to comply with current or future regulations or changes in the
interpretation of existing regulations in a particular country could result in
any of the following events:

  .  the suspension or cessation of sales in that country;

  .  the imposition of restrictions in our development efforts and those of
     our customers;

  .  current products becoming obsolete; or

  .  an increase in the opportunities for additional competition.

   These current or future regulations or changes in the interpretation of
existing regulations could require us to modify our products and incur
substantial costs.

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

Facilities

   We lease approximately 51,400 square feet of facilities in two locations.
Our headquarters is a 47,000 square foot facility in Sunnyvale, California.
This facility accommodates the following departments: sales and marketing, the
majority of our research and development, manufacturing, administration and
finance. The term of the lease for this facility expires in June 2006. We also
lease approximately 4,400 square feet in Petaluma, California, which is used
for the remainder of our research and development department.

Employees

   As of March 31, 2000, we had 159 employees, including 58 in manufacturing,
44 in research and development, 40 in sales, marketing and customer service and
17 in finance and administration. We are not a party to any collective
bargaining agreement. We believe that relations with our employees are good.

Legal Proceedings

   We are not currently a party to any material legal proceedings.

Board of Directors

 Terms

   Our current directors will serve their terms until the next annual meeting
of stockholders and the election of their successors. At the next annual
meeting of stockholders, the board of directors will be divided into three

                                       45
<PAGE>

classes. The first class of directors will be nominated to serve for a term of
three years, the second class for a term of two years, and the third class for
a term of one year. After that, each director will be nominated to serve for a
term of three years. Directors will hold office until the annual meeting of
stockholders in the year in which the term of their class expires and until
their successors have been duly elected and qualified. Executive officers are
appointed by, and serve at the discretion of, the board of directors.

 Committees

   Our board of directors intends to establish an audit committee and a
compensation committee. The audit committee will consist of at least three
independent directors. The audit committee will make recommendations to the
board of directors about the selection of independent auditors, review the
results and scope of the audit and other services provided by our independent
auditors, and review and evaluate our audit control functions.

   The compensation committee will consist of at least two independent
directors. The compensation committee will make recommendations regarding the
1999 Western Multiplex Corporation Stock Incentive Plan, the Western Multiplex
Employee Stock Purchase Plan and the salaries, incentives and other forms of
compensation for our employees and consultants.

 Compensation

   During 1999, our directors were not compensated for serving as members of
the board of directors. After the offering, we will pay all non-employee
directors an annual retainer for serving on the board or as chairman of a
standing committee of the board and an amount for each board and committee
meeting attended in person or via teleconference. The amounts will be
determined prior to the offering. In addition, all directors will be reimbursed
for expenses incurred in attending meetings of the board of directors and its
committees.

   Our directors are entitled to receive option grants under the 1999 Western
Multiplex Corporation Stock Incentive Plan. However, no awards have been
granted as of April 20, 2000. Any awards which may be granted in the future
will be determined by the compensation committee. However, our full board of
directors must approve all awards granted under the plan to directors who
beneficially own more than 10% of our outstanding common stock and, as a
result, are subject to Section 16 of the Securities and Exchange Act of 1934.

   On November 1, 1999, we issued warrants to purchase a total of 2,918,400
shares of our common stock at an exercise price of $.50 per share to Seaview
Holdings, L.L.C., which is wholly-owned by Mr. Zakin, our Chief Executive
Officer and Chairman of our board of directors. We also issued warrants to
purchase a total of 1,451,600 shares of our common stock at an exercise price
of $.50 per share to The Michael and Roberta Seedman Revocable Trust, a trust
for which Mr. Seedman, a member of our board of directors, is both trustee and
a beneficiary. Warrants held by Seaview Holdings to purchase 1,140,000 shares
of our common stock and warrants held by The Seedman Revocable Trust to
purchase 570,000 shares of our common stock are presently exercisable. Upon
completion of the offering, all of the warrants held by Seaview Holdings and
The Seedman Revocable Trust will become exercisable upon completion of the
offering. For additional information about the terms of these investments, see
"Material Relationships and Related Transactions--Co-Investment Agreements."

Western Multiplex Corporation 2000 Stock Option Plan for Non-Employee Directors

   We intend to adopt the Western Multiplex Corporation 2000 Stock Option Plan
for Non-Employee Directors. The plan will provide for the issuance of a maximum
of 1,500,000 shares of our common stock pursuant to the grant of non-qualified
stock options to newly elected members of the board of directors who are not
our employees. The Stock Option Plan for Non-Employee Directors will be a self-
governing plan that will require minimal discretionary action by any
administrative body to effect any transaction under the plan. To the extent
that any questions of administration arise, they will be resolved by our board
of directors.

                                       46
<PAGE>

   The exercise price of any option granted under this plan will be the fair
market value of our common stock on the date the option is granted. A non-
employee who becomes a director will initially be granted an option to purchase
100,000 shares of our common stock, of which one-third will vest immediately.
The option will then become vested as to each additional one-third of the
shares on the first and second anniversaries of the date of the initial grant,
so long as the director continues to serve on our board of directors on each of
the vesting dates. In addition, so long as a director continues to serve on our
board of directors, the director will, as of the third anniversary of the date
of the initial grant and every three years after that, receive an additional
option to purchase 15,000 shares, of which one-third of the shares will vest
immediately. The option will then become vested as to each additional one-third
of the shares on the first and second anniversaries of the date of each
additional grant, so long as the director continues to serve on our board of
directors on each of the vesting dates.

Compensation Committee Interlocks and Insider Participation

   During the fiscal year ended December 31, 1999, we did not have a
compensation committee. However, Messrs. Zakin and Zoufonoun participated in
deliberations with our board of directors regarding executive officer
compensation. None of our executive officers served as a member of the board of
directors or compensation committee of any entity that has one or more officers
serving as a member of our board of directors.

Executive Compensation

   Summary compensation. The following table sets forth information regarding
executive compensation for services rendered during the fiscal year ended
December 31, 1999 by our Chief Executive Officer and our other four most highly
paid executive officers whose salary and bonus for the last fiscal year
exceeded $100,000. The compensation summarized in this table does not include
medical, group life insurance or other plan benefits that are available
generally to all of our salaried employees or perquisites or other personal
benefits that do not in the aggregate exceed the lesser of $50,000 or 10% of
the officer's salary and bonus.

Stockholder's Agreements

   Each of our executive officers and all of our employees who have either
purchased shares of our common stock or received options to purchase shares of
our common stock, have entered into stockholder's agreements with us. Under
those agreements, the employees agreed not to transfer any shares of our common
stock for 180 days following the completion of the offering. There is an
exception for transfers to trusts and estates for estate planning purposes and
for sales of a pro rata portion of these shares of our common stock in
connection with a sale by Ripplewood Partners of its shares of our common
stock. In addition, following the completion of the offering and the expiration
of the 180-day lock-up period, employee stockholders will have the right to
sell shares of our common stock in any registration statements that we file.

   Generally, under the employee stockholder's agreements, we have the right to
repurchase our shares and options from our employees if they cease to be
employed by us. Furthermore, our employees and their permitted transferees who
have entered into a stockholder's agreement with WMC Holding for options to
purchase shares of common stock of WMC Holding agree to vote all of the shares
of common stock of WMC Holding held by them in the same manner as Ripplewood
Partners on all matters acted upon at any annual or special meeting of
stockholders of WMC Holding or by written consent in place of a meeting, and
appoint Mr. Zakin as their proxy to so vote.

$50,000. He is not eligible for any bonus. Mr. Zakin's employment term is not

prior to a change of control, as defined in the 1999 Western Multiplex
Corporation Stock Incentive Plan, all of Ms. Huber's outstanding, unvested
time-based options will accelerate and become fully vested and immediately

stock held by Ms. Huber, other than those imposed by any underwriters in the
offering, will lapse.

   If we terminate Ms. Huber's employment without cause or if she terminates
her employment for good reason, as described in the employment agreement, we
will be required, for a period of 12 months, to pay her base salary, her annual
target bonus for the year in which her employment terminates, which will equal
up to 40% of her base salary at that time, and continue her medical and other
benefits. In addition, Ms. Huber will receive any accrued vacation days, any
deferred compensation and any unreimbursed expenses. For purposes of the
employment agreement, a change of control of us does not qualify as good reason
for Ms. Huber to leave. We may terminate Ms. Huber's employment at any time,
and Ms. Huber may terminate her employment on 90 days' prior written notice.
Ms. Huber has agreed not to disclose any confidential information pertaining to
our business. Furthermore, she has agreed not to compete with us during her

1999 Western Multiplex Corporation Stock Incentive Plan

   The 1999 Western Multiplex Corporation Stock Incentive Plan was adopted by
our board of directors and approved by our stockholders in November 1999. The
plan provides for the issuance of a maximum of 6,000,000 shares of common stock
pursuant to the grant of incentive stock options, non-qualified options, stock
appreciation rights and various other stock-based awards to our employees,
directors and consultants. The 1999

                                       50
<PAGE>

Stock Incentive Plan is administered by the board of directors and, in the
future, will be administered by the compensation committee, which has the
authority to determine recipients of awards under the plan.

   The exercise price of the options and the vesting periods, expiration dates
and other terms of awards under the plan will be determined by the compensation
committee. However, the exercise price of any option granted to any stockholder
who owns more than 10% of the total combined voting power of all of our
outstanding capital stock, or that of our parent or subsidiary corporations,
cannot be less than 110% of the fair market value of the shares underlying the
option on the date of the grant. In no event may the exercise price of an
option be less than 100% of the fair market value of the shares underlying the
option on the date of grant. In addition, an option may not vest at a rate that
is less than 20% per year over five years from the date the option is granted.

   Upon a change of control, as defined in the 1999 Stock Incentive Plan, the
compensation committee may, but is not obligated to, (1) provide that any
outstanding award that is unvested as of the date of the change of control will
become immediately vested and (2) provide for a cash payment to be made to
holders of outstanding awards in the event the awards are canceled. In the case
of options and stock appreciation rights, the cash payment would be equal to
the difference between the fair market value of the shares underlying the
option or stock appreciation rights and the aggregate exercise price of the
options or stock appreciation rights, as applicable. Awards are not
transferable except by will or by the laws of descent or distribution or
pursuant to a qualified domestic relations order.

   As of March 31, 2000, we had granted options for the purchase of 4,578,227
shares of our common stock under the 1999 Stock Incentive Plan. No options have
vested, and none have been exercised as of March 31, 2000. However, options to
purchase 724,000 shares of our common stock will vest upon completion of the
offering.

Western Multiplex Employee Stock Purchase Plan

   We intend to adopt the Western Multiplex Employee Stock Purchase Plan. It
will be submitted to our stockholders for their approval prior to the closing
of the offering. If approved, it will become effective on the date of the
offering. The total number of shares of our common stock that will be reserved
for issuance under the plan will be determined prior to the offering.

   The Western Multiplex Employee Stock Purchase Plan is intended to qualify as
an employee stock purchase plan under Section 423 of the Internal Revenue Code
of 1986. It will be administered by the compensation committee of the board of
directors, which has the authority to interpret the plan and establish, amend
and rescind any rules and regulations relating to the plan. Under the plan, all
our employees are given the option to elect to have us deduct a portion of
their annual compensation, including base salary, annual bonuses, commissions,
overtime and shift pay, during a 24-month offering period established by the
board of directors. It is expected that during the offering period, there will
be six-month window periods, or purchase periods, when plan participants will
have the opportunity to use their payroll deductions to purchase shares of our
common stock at a per share purchase price equal to 85% of the lesser of the
fair market value of the shares on the first day of the offering period or on
the last date of the purchase period. A plan participant is only entitled to
purchase, in any given calendar year, a maximum number of shares of our common
stock equal to the least of:

  .  2,500 shares;

  .  the number of shares determined by dividing the amount accumulated in a
     plan participant's payroll deduction account during the applicable
     offering period by the purchase price described above; and

  .  in any given calendar year, shares with an aggregate fair market value
     equal to $25,000, as determined on the first day of any offering period.

   When a plan participant exercises his or her option to purchase shares of
our common stock under the plan, it is expected that we will purchase shares of
common stock for that plan participant, in accordance with

                                       51
<PAGE>

the terms and limitations described above, and that we will deposit those
shares into an account established for each plan participant with a stock
brokerage or other financial services firm designated by the compensation
committee. The shares must remain in the account for a period of at least two
years from the first day of the offering period and for at least one year from
the last day of the purchase period. This restriction is in place to prevent
plan participants from engaging in a disqualifying disposition of their shares
purchased pursuant to the plan. A disqualifying disposition of shares by a
participant would cause the participant to lose the favorable tax treatment
available to that plan participants upon a sale or other disposition of shares
acquired pursuant to the plan. In addition, in the event of a change of control
of us, the compensation committee may, in its sole discretion, take whatever
actions it deems necessary or desirable with respect to any option or offering
period as of the date of the change of control.

Western Multiplex Corporation 401(k) Profit Sharing Plan

   In October 1999, we adopted the Western Multiplex Corporation 401(k) Profit
Sharing Plan, which covers our full time employees who are at least 21 years
old and have completed six months of service with us. The 401(k) Plan is
governed by the Employee Income Retirement Security Act of 1974. The 401(k)
Plan is intended to qualify under Section 401(k) of the Internal Revenue Code
of 1986 so that contributions to it by employees, and the investment earnings
on those contributions, are not taxable to employees until distributed to the
employees pursuant to the terms of the plan. Under the 401(k) Plan, employees
may elect to reduce their current compensation by up to the lesser of 15% of
their annual compensation or the statutorily prescribed annual limit, which is
$10,500 for 2000, and have this amount contributed to the 401(k) Plan. Under
the plan, we make matching contributions equal to 100% of an employee's
contribution, up to 4% of the employee's annual compensation. We may also elect
to make discretionary contributions under the plan. Employees are at all times
fully vested in their contribution, and in all contributions made by us.

Ubiquity Communication Plans

   In connection with our acquisition of Ubiquity Communication, Inc. on March
24, 2000, we assumed the obligations under Ubiquity Communication's equity
incentive plans. As a result, all options granted under the Ubiquity
Communication equity incentive plans became options to purchase shares of our
common stock. We do not intend to make any future grants under these plans.

   Ubiquity Communication maintained three equity incentive plans, the 1999
Stock Plan, the 1998 Stock Plan and the 1997 Stock Option Plan. The 1998 and
1999 plans provide for the grant of non-qualified and qualified stock options
and restricted stock. The 1997 plan provides for the grant of non-qualified and
qualified stock options. Under the plans, grants could be made to Ubiquity
Communication employees, consultants and directors. All of the plans will be
administered and interpreted by our board of directors or compensation
committee.

   Generally, the plans also provided that all qualified stock options be
granted with an exercise price at least equal to 100% of the fair market value
of the underlying shares and that all nonqualified stock options be granted
with an exercise price at least equal to 85% of the fair market value of the
underlying shares. In either case, the exercise price must be 110% of the fair
market value for an optionholder who owns stock representing more than 10% of
the voting power of all classes of stock. The plans also provide that, in the
event of a merger or other corporate transaction, options could be granted with
a per share exercise price other than as described above. All options issued
under the plans must vest no less frequently than 20% per year over five years
from the date the options are granted, and with respect to the 1998 and 1999
plans, all restricted stock must also vest no less frequently than 20% per year
over five years from the date the stock is granted.

Limitations on Directors' and Executive Officers' Liability and Indemnification

   Our bylaws and our amended and restated certificate of incorporation provide
that we will indemnify our current or former directors or officers to the
fullest extent permitted by Delaware law.

                                       52
<PAGE>

   Our amended and restated certificate of incorporation provides that our
directors will not be personally liable to us or to our stockholders for
monetary damages for any breach of fiduciary duty except liability for:

  .  any breach of the director's duty of loyalty;

  .  acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law;

  .  unlawful distributions and loans to insiders;

  .  unlawful payments of dividends or unlawful stock repurchases or
     redemptions; or

  .  any transaction from which the director derived an improper personal
     benefit.

   In addition to the indemnification provided for in our bylaws and amended
and restated certificate of incorporation, under the employment and co-
investment agreement with Mr. Zakin and the co-investment agreement with Mr.
Seedman, we agreed to indemnify each of them to the fullest extent permitted by
law against any liability incurred by them by reason of the fact that they were
serving in an indemnified capacity. This includes any liabilities resulting
from an actual or alleged breach or neglect of duty, error, misstatement or
misleading statement or act. However, we will not have to indemnify either of
them for:

  .  fraud, willful violation of law, gross negligence or breach of their co-
     investment agreements; or

  .  the receipt by either of them of a personal benefit to which they are
     not entitled.

   With respect to Mr. Zakin, an indemnified capacity includes all past,
present and future service as one of our executive officers or directors, or,
at our request, as a member, director, officer, manager, employee, agent,
fiduciary or trustee of another corporation, limited liability company,
partnership, joint venture, trust, employee benefit plan or other entity or
enterprise. With respect to Mr. Seedman, an indemnified capacity includes all
past, present and future service as one of our directors, or, at our request,
as a member, director, officer, manager, employee, agent, fiduciary or trustee
of another corporation, limited liability company, partnership, joint venture,
trust, employee benefit plan or other entity or enterprise.

   We also have agreed with Mr. Zakin and Mr. Seedman in their employment
agreements to provide directors' and officers' liability insurance to them in
their capacity as directors, and to Mr. Zakin in his capacity as an officer. We
have purchased directors' and officers' liability insurance for all of our
directors and executive officers.

   We believe these provisions and agreements are necessary to attract and
retain qualified persons as directors and executive officers. This limitation
of liability and indemnification does not affect the availability of equitable
remedies. In addition, it is the position of the Commission that
indemnification for liabilities arising under federal or state securities laws
is against public policy and not enforceable.

   At present, there is no litigation or proceeding involving any of our
directors or executive officers in which indemnification is required or
permitted, and we are not aware of any threatened litigation or proceeding that
may result in a claim for such indemnification.

                             PRINCIPAL STOCKHOLDERS

   At March 31, 2000, we had total authorized capital of 100,000,000 shares of
our Class A common stock and 100,000,000 shares of our Class B common stock and
692,772 shares of our Class A common stock and 41,869,351 shares of our Class B
common stock was issued and outstanding. We also had 42,000,000 shares of our
Class B common stock held in treasury. At March 31, 2000, WMC Holding Corp.
owned 39,824,351 shares of our Class B common stock. Immediately prior to the
completion of the offering, pursuant to a plan of reorganization, WMC Holding
will transfer all of its assets and liabilities, consisting solely of shares of
our Class B common stock, to us in exchange for newly-issued shares of our
Class A common stock. Each share of Class B common stock will be exchanged for
one share of Class A common stock. After this exchange, WMC Holding Corp. will
convert from a corporation to a limited liability company under Delaware law.
In addition, all shares of our Class B common stock will automatically convert
at a one-to-one ratio into shares of our Class A common stock immediately prior
to the completion of the offering.

   The following table sets forth information about the beneficial ownership of
our common shares as of the closing date for the offering assuming the
automatic conversion of our Class B shares into Class A shares, by the
following:

  .  each person known by us to own beneficially more than 5% of the
     outstanding common stock;

  .  each of our directors;

  .  each of our executive officers; and

  .  all of our directors and executive officers as a group.

   Beneficial ownership includes shares over which the indicated beneficial
owner exercises voting or investment power. Shares of common stock that we may
issue upon the exercise of options or warrants currently exercisable or
exercisable within 60 days of the closing date for the offering are deemed
outstanding for computing the percentage of ownership of the person holding the
options or warrants but are not deemed outstanding for computing the percentage
ownership of any other person. Except as we otherwise indicate, we believe the
beneficial owners of the common stock listed below, based on information
provided by them, have sole voting and investment power over the number of
shares listed opposite their names, subject to community property laws where
applicable.

                MATERIAL RELATIONSHIPS AND RELATED TRANSACTIONS

   Other than normal compensation arrangements which are described under
"Management" above, the following is a description of transactions, since
January 1, 1999, to which we have been a party, in which the amount involved in
the transactions exceeds $60,000, and in which any of our directors, executive
officers or record or beneficial holders of more than 5% of our common stock
has had or will have a beneficial direct or indirect material interest.

Acquisition Agreement

   Pursuant to an acquisition agreement, on November 1, 1999, WMC Holding
Corp., a subsidiary of Ripplewood Partners, L.P., purchased 35,955,000 shares
of our Class B common stock from GTI Acquisition Corp., a wholly-owned
subsidiary of Glenayre Technologies, Inc., in a transaction accounted for as a
recapitalization.

   As of March 31, 2000, (1) Ripplewood Partners and Ripplewood Employee Co-
Investment Fund together owned approximately 80% of WMC Holding; (2) Seaview
Holdings, L.L.C., which is wholly-owned by Jonathan N. Zakin, our Chief
Executive Officer and Chairman of our board of directors, owned approximately
5% of WMC Holding; and (3) The Michael and Roberta Seedman Revocable Trust, of
which Michael Seedman, a member of our board of directors, is trustee and a
beneficiary, owned approximately 5% of WMC Holding.

   Under the acquisition agreement, we redeemed 42,000,000 shares of our Class
B common stock from GTI Acquisition for $21.0 million. In order to effect the
redemption our Class B common stock from GTI Acquisition, on November 1, 1999,
we entered into a credit agreement with Credit Suisse First Boston, as agent,
consisting of two term loans and a revolving credit facility. We borrowed a
total of $22.0 million in term loans and $2.0 million in revolving credit loans
under this credit agreement. Following the redemption, WMC Holding purchased
35,955,000 shares of our Class B common stock from GTI Acquisition, at a
purchase price of $.50 per share. Following the closing, a purchase price
adjustment of approximately $1.4 million was made, reducing the total purchase
price to $16.5 million.

   Subject to various exceptions in the acquisition agreement, each of GTI
Acquisition and Glenayre Technologies agreed on behalf of itself and its
affiliates not to compete with us until after November 1, 2002. In addition,
they agreed not to induce or attempt to induce any of our employees to leave,
and not to hire any of our employees who were employed by us within 90 days of
being hired by them.

Intellectual Property Agreements

   Assignment Agreement. Prior to the November 1, 1999 acquisition of us by WMC
Holding, we were an indirect wholly-owned subsidiary of Glenayre Technologies,
Inc. All of our intellectual property was owned by an affiliate of Glenayre
Technologies under an intercompany agreement. In connection with the
acquisition by WMC Holding, we were removed from that intercompany agreement
and entered into an intellectual property assignment agreement under which
Glenayre assigned to us:

  .  all intellectual property rights that we owned prior to the November 1,
     1999 acquisition or that we developed independently from Glenayre
     following the acquisition, to the extent Glenayre may claim any interest
     in this intellectual property; and

  .  two patent applications.

   License Agreement. On November 1, 1999, we also entered into an intellectual
property license agreement with Glenayre. Under the agreement, Glenayre granted
us a license to use the name "Glenayre" for a one-year period which expires on
November 1, 2000. In addition, we granted Glenayre a royalty-free license to
two patent applications, and to use any trademarks we own in connection with
the depletion of inventory

                                       57
<PAGE>

held by Glenayre on the date of the license. Except for the one-year license to
use Glenayre's name, the licenses granted to us are perpetual and will remain
in place for as long as our use of the intellectual property is necessary and
as long as we do not materially breach our obligations under the license
agreement. The license granted to Glenayre relating to the patent applications
terminates when the related patents expire and the license to use our
trademarks terminate as soon as Glenayre has depleted all inventory bearing our
mark.

   We believe the terms of these arrangements are as favorable to us as any we
could have obtained from a third party on an arms-length basis.

Stockholders' Agreement

   On October 31, 1999, we entered into a stockholders' agreement with GTI
Acquisition Corp. and its corporate parent, Glenayre Technologies, Inc., which
was also our former corporate parent. As of March 31, 2000, GTI Acquisition
held 2,045,000 shares of our Class B common stock, or approximately 4.8% of our
outstanding common stock, which will be automatically converted into 2,045,000
shares of our Class A common stock upon completion of the offering. Subject to
various exceptions, under the stockholders' agreement, GTI Acquisition and its
permitted transferees, as defined in the Stockholders' Agreement, agreed not to
transfer their shares of our common stock until after October 31, 2001. In
addition, GTI Acquisition and its permitted transferees have granted us a right
of first refusal in any sale of their shares of our common stock after that
date. If GTI Acquisition or any of its permitted transferees receives an offer
to purchase any of its shares of our common stock, it cannot accept the offer
until it first offers to sell the shares to us or to an affiliate of Ripplewood
Partners. These restrictions and rights will terminate upon completion of the
offering.

   If either of WMC Holding Corp. or Ripplewood Partners wants to sell any
shares of our common stock to any person other than one of its affiliates or to
our affiliates, officers, directors or employees, then Glenayre and its
permitted transferees have the right to participate in the sale and sell a pro
rata portion of their shares of common stock in that sale. If WMC Holding or
any of its stockholders receives an offer from a third party to purchase a
majority of our common stock and accepts the offer, then GTI Acquisition and
its permitted transferees must sell a pro rata percentage of our common stock
to the third party on the same terms as any sale by WMC Holding or Ripplewood
Partners. These rights will terminate upon completion of the offering.

   In the event that we issue additional common stock to WMC Holding,
Ripplewood Partners or any of their affiliates, at any time before October 31,
2001, and this issuance reduces GTI Acquisition's or its permitted transferees'
ownership to less than 5.1% of our outstanding common stock, then in certain
cases, we must grant GTI Acquisition and its permitted transferees the right to
purchase a pro rata number of shares of our common stock in the proposed
issuance based on GTI Acquisition's and its permitted transferees' current
ownership percentage. However, the provisions described in the preceding
sentence shall not be applicable to any issuance of our common stock to WMC
Holding in connection with the issuance of common stock of WMC Holding by WMC
Holding to any of our officers, directors or employees. These rights will
terminate upon completion of the offering.

   In addition, for as long as GTI Acquisition or any of its permitted
transferees own shares of our common stock, they have the right to sell all or
any portion of our common stock held by them in any registered offering of our
common stock that is initiated by us or by WMC Holding, other than registered
offerings in connection with securities issued in business combination
transactions, pursuant to certain employee benefit plans or the offering.

Co-Investment Agreements

   In October 1999, we entered into an employment and co-investment agreement
with Mr. Zakin, our Chief Executive Officer and Chairman of our board of
directors, and his wholly-owned affiliate, Seaview Holdings, L.L.C. Under this
agreement, Seaview Holdings purchased 1,900,000 shares of common stock of WMC
Holding, and we issued warrants to purchase a total of 2,918,400 shares of our
common stock at an exercise

                                       58
<PAGE>

price of $.50 per share to Seaview Holdings. Warrants held by Seaview Holdings
to purchase 1,140,000 of our common stock are presently exercisable. Upon
completion of the offering, all of the warrants held by Seaview Holdings will
become exercisable.

   In October 1999, we also entered into a co-investment agreement with Mr.
Seedman, a member of our board of directors, and The Michael and Roberta
Seedman Revocable Trust, of which Mr. Seedman is both trustee and a
beneficiary. Under the co-investment agreement, The Seedman Revocable Trust
purchased 1,900,000 shares of common stock of WMC Holding, and we issued
warrants to purchase a total of 1,451,600 shares of our common stock at an
exercise price of $.50 per share to The Seedman Revocable Trust. Warrants held
by The Seedman Revocable Trust to purchase 570,000 shares of our common stock
are presently exercisable. Upon completion of the offering, all of the warrants
held by The Seedman Revocable Trust will become exercisable.

   Seaview Holdings and its transferees have generally agreed to vote all of
their shares of our common stock and all of their shares of the common stock of
WMC Holding in the same manner as Ripplewood Partners or WMC Holding votes on
all matters acted upon at any annual or special meeting of stockholders or by
written consent in place of a meeting and agrees to appoint Mr. Zakin as its
proxy to vote.

   If Mr. Zakin's employment or Mr. Seedman's directorship terminates, we will
have an option to purchase the shares of our common stock and the warrants to
purchase shares of our common stock held by Seaview Holdings and The Seedman
Revocable Trust. The purchase price for the common stock will be the fair
market value of our common stock. The purchase price for the warrants will be
the fair market value per share of our common stock less the exercise price per
share pursuant to the warrants, multiplied by the number of shares of common
stock issuable upon the exercise of the warrants.

   Generally, Seaview Holdings and The Seedman Revocable Trust may not transfer
their shares of our common stock and the warrants that it owns to any third
party without the consent of Ripplewood, other than transfers to Ripplewood or
to us, except under the following circumstances:

  .  If Ripplewood Partners wants to transfer its shares of our common stock
     to an unrelated third party, then Seaview Holdings and The Seedman
     Revocable Trust may sell a pro rata portion of their shares of our
     common stock and vested warrants on the same terms and at the same price
     as the sale with Ripplewood Partners.

  .  If Ripplewood Partners wants to sell our common stock to an third party,
     then Ripplewood Partners can require Seaview Holdings and The Seedman
     Revocable Trust sell a pro rata portion of their shares of our common
     stock and vested warrants to the third party on the same terms and at
     the same price as the sale by Ripplewood Partners.

  .  At any time after the offering of our common stock, Seaview Holdings and
     The Seedman Revocable Trust will each have the right to demand that we
     register their shares of our common stock. We may postpone any demand
     registration by Seaview Holdings or The Seedman Revocable Trust if it
     will interfere with any pending corporate actions or plans. In addition,
     if Ripplewood Partners demands that we register its shares of our common
     stock or if we register a public offering of our common stock, Seaview
     Holdings and The Seedman Revocable Trust will each have the right to
     register their shares of our common stock as well.

   If a transfer of shares of our common stock or warrants is made in violation
of the employment and co-investment agreement with Mr. Zakin or the co-
investment agreement with Mr. Seedman, or made pursuant to a forced transfer
such as a death, a bankruptcy or a court order, then Ripplewood Partners has
the right to purchase all the shares of our common stock or warrants from the
transferee.

Promissory Notes from Officers

   Messrs. Zoufonoun, Corsentino, Tavormina, Cohen and Saefke and Ms. Huber
issued promissory notes to us in the total amount of $876,150 in connection
with their purchase of a total of 1,770,000 shares of common stock of WMC
Holding. The notes accrue interest at a rate of 8% per year, compounded and
payable annually.

                                       59
<PAGE>

   The principal amount of each of the promissory notes is payable on the
earlier of:

  .  the thirtieth day after we exercise a right to repurchase the employee's
     shares of our common stock under the employee's stockholder's agreement;
     and

  .  the tenth anniversary of the promissory note.

   The employees borrowing from us also entered into pledge agreements under
which we take a security interest in their shares and options. Under the pledge
agreement, we have the right to take their shares and options back should they
default under the terms of the loan. We also have the right to require the
employees to use the proceeds from the sale of any shares which were purchased
with the loans to pay down the amount outstanding on their loans. If, after we
have collected on the pledged shares and used the proceeds to offset the
amounts owed, the borrower continues to owe us money, we can seek recourse from
the employee's other personal assets or income for up to half of the principal
amount of the loan.

   In addition, in connection with our acquisition of Ubiquity Communication,
Inc., we assumed a promissory note between Mr. Tavormina and Ubiquity
Communication in the principal amount of $29,555. The note accrues interest at
a rate of 8% per year.

Management Services Agreement

   In November 1999, we entered into a management services agreement with
Ripplewood Holdings, L.L.C., the general partner of Ripplewood Partners, L.P.,
which is one of the principal investors in WMC Holding. Under this agreement,
Ripplewood Holdings agrees to provide consulting and management advisory
services to us, and we agree to pay Ripplewood Holdings an annual fee equal to
1% of our net revenue. This agreement terminates upon completion of the
offering.

Acquisition of Ubiquity Communication, Inc.

   On March 24, 2000, we acquired Ubiquity Communication, Inc., located in
Petaluma, California. Through the acquisition, we acquired technology that will
enable us to develop our point-to-multipoint systems. At the time of the
acquisition, Ubiquity Communication had seven employees, including six
engineers. We issued 692,772 shares of our common stock to the former owners of
Ubiquity Communication and reserved 137,727 shares for issuance upon the
exercise of the Ubiquity options we assumed. We accounted for the transaction
using the purchase method of accounting. Accordingly, we have recorded
purchased intangibles and goodwill of $6.0 million to be amortized over a three
year period. We intend to treat the acquisition of Ubiquity Communication as a
tax-free reorganization.

Restructuring

   Immediately prior to the completion of the offering, pursuant to a plan of
reorganization, WMC Holding Corp. will transfer all of its assets and
liabilities, consisting solely of shares of our Class B common stock to us in
exchange for newly-issued shares of our Class A common stock. Each share of
Class B common stock will be exchanged for one share of Class A common stock.
After this exchange, WMC Holding will convert from a corporation to a limited
liability company under Delaware law, and will change its name to WMC Holding
L.L.C.

                          DESCRIPTION OF CAPITAL STOCK

General

   Upon the closing of the offering, we will be authorized to issue up to
100,000,000 shares of Class A common stock, par value $.01 per share, and
5,000,000 shares of undesignated preferred stock, par value $.01 per share. As
of March 31, 2000, there were 692,772 shares of Class A common stock
outstanding held of record by 30 stockholders and 38,000,000 shares of Class B
common stock outstanding held of record by two stockholders. Immediately prior
to the completion of the offering, all shares of Class B common stock will
automatically convert into shares of Class A common stock at a ratio of one
share of Class B common stock to one share of Class A common stock. Following
the offering, there will be     shares of Class A common stock outstanding, or
    shares if the underwriters exercise their over-allotment option in full,
assuming no exercise of outstanding options or warrants.

Amended and Restated Certificate of Incorporation

   Our authorized capital stock will, upon the closing of the offering, consist
of 100,000,000 shares of Class A common stock, 1,000,000 shares of Class B
common stock and 5,000,000 shares of preferred stock. No other class of capital
stock has been authorized. The following information relates only to our
amended and restated certificate of incorporation.

Class A Common Stock

   Upon the closing of the offering, we expect to have 42,562,123 shares of
Class A common stock issued and outstanding, excluding shares sold in the
offering.

   The holders of Class A common stock are entitled to one vote per share on
all matters submitted to a vote of the stockholders, including the election of
directors. As of March 31, 2000, there were 30 holders of record of our Class A
common stock. Our Class A common stock does not have cumulative voting rights,
which means that a majority of the outstanding Class A common stock voting in
the election of directors can elect all directors being elected. The holders of
Class A common stock are entitled to receive dividends when, as and if declared
by our board of directors out of legally available funds. Upon liquidation or
dissolution, the holders of Class A common stock will be entitled to share
ratably in the assets legally available for distribution to stockholders after
the payment of liabilities and subject to any prior rights of holders of
preferred stock outstanding at the time. The holders of Class A common stock
have no conversion, redemption, preemptive or subscription rights under our
second amended and restated certificate of incorporation. The rights,
preferences and privileges of holders of our Class A common stock are subject
to the rights of the holders of any shares of any series of preferred stock
which we may issue in the future.

Class B Common Stock

   Each of the 41,869,351 shares of Class B common stock currently issued and
outstanding will be automatically converted into one share of Class A common
stock immediately prior to completion of the offering. The Class B common stock
is treated for all purposes like the Class A common stock, except that the
Class B common stock has ten votes per share. The Class A and Class B common
stock vote together as a single class on all matters. Upon the closing of the
offering, due to the conversion of shares of Class B common stock into shares
of Class A common stock, no shares of Class B common stock will be issued and
outstanding.

Preferred Stock

   We have 5,000,000 shares of undesignated preferred stock authorized for
issuance. Upon the closing of the offering, no shares of preferred stock will
be issued or outstanding.


                                       61
<PAGE>

   Our board of directors may, without any additional action by our
stockholders at the time of issuance, fix the dividend rights, and rates,
conversion rights or rights of exchange, voting rights, terms of redemption
and, redemption price or prices, liquidation preferences and any other rights,
preferences, privileges, and restrictions of any series of preferred stock as
well as the number of shares constituting any series and the designation of the
series. We have no present plans to issue any shares of preferred stock.

Warrants

   In November 1999, we issued warrants to purchase a total of 2,918,400 shares
of our common stock at an exercise price of $.50 per share to Seaview Holdings,
Mr. Zakin's wholly-owned affiliate. As of the date of this prospectus, warrants
to purchase 1,140,000 shares of our common stock held by Seaview Holdings are
presently exercisable. Upon completion of the offering, all of the warrants
held by Seaview Holdings will become exercisable.

   In November 1999, we issued to The Michael and Roberta Seedman Revocable
Trust warrants to purchase 1,451,600 shares of our common stock at an exercise
price of $.50 per share. As of the date of this prospectus, warrants to
purchase 570,000 shares of our common stock held by The Seedman Revocable Trust
are presently exercisable. Upon completion of the offering, all of the warrants
held by The Seedman Revocable Trust will become exercisable.

Registration Rights

   Demand Registrations. After the 180-day lock-up period following the closing
of the offering, the holders of 41,869,351 shares of our common stock and the
holders of 4,370,000 warrants to purchase shares of our common stock will have
rights to require us to register their shares for sale under the Securities Act
of 1933, as amended. Following the expiration of the lock-up period, Seaview
Holdings and The Seedman Revocable Trust each have the right to make two
separate written demands on us to register their shares of our common stock,
including the shares of common stock for which their warrants can be exercised.
Ripplewood Partners and its permitted transferees each have the right to have
their shares of our common stock registered pro rata with Seaview Holdings and
The Seedman Revocable Trust whenever either of them makes a written demand on
us to register their shares of our common stock. In addition, they will each
have the right to have their shares of our common stock registered pro rata
with Ripplewood Partners any time that we do a registered offering of our
common stock or any time Ripplewood Partners demands that we register any of
its shares of our common stock. Glenayre also has the right to include a
portion of [its] shares in any registered offering of our common stock.

   All of the registration rights are subject to conditions and limitations,
including the right of underwriters to limit the number of shares included in a
registration statement and to exclude any holder's shares from a registration
initiated by us for our account. We have agreed to pay the expenses of those
registrations in most cases. In cases where Seaview Holdings or The Seedman
Revocable Trust demand that we register their shares of our common stock, the
demanding party has the right to select the underwriter, assuming the selection
is reasonably satisfactory to Ripplewood Partners. However, we have the right
to postpone any demand registration by Seaview Holdings or The Seedman
Revocable Trust if the registered offering would interfere with a pending
financing, merger, sale of assets, recapitalization or similar corporate action
or with an offering of our common stock by Ripplewood Partners or any of its
permitted transferees.

   Piggyback Registrations. For as long as GTI Acquisition or any of its
permitted transferees own shares of our common stock, they have the right to
sell all or any portion of our common stock held by them in any registered
offering of our common stock that is initiated by us or by WMC Holding, other
than registered offerings in connection with securities issued in business
combination transactions or pursuant to certain employee benefit plans. These
registration rights are subject to conditions and limitations, including the
right of underwriters to limit the number of shares included in a registration.

   In addition, following the expiration of the 180-day lock-up period
following the closing of a firmly underwritten registered public offering of
our common stock, employee stockholders and their permitted

                                       62
<PAGE>

transferees, have the right to sell all or any portion of our common stock held
by them in any registered offering of our common stock that is initiated by us,
WMC Holding or Ripplewood Partners. These registration rights are subject to
conditions and limitations as determined in good faith by our board of
directors, the board of directors of WMC Holding or by Ripplewood Partners and
about which employee stockholders have received notice.

Anti-Takeover Provisions in Delaware Law and Our Amended and Restated
Certificate of Incorporation

   We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, Section 203 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 of the transaction in
which the person became an interested stockholder, unless the business
combination is approved in a prescribed manner. A business combination includes
mergers, asset sales or other transactions resulting in a financial benefit to
the stockholder. An interested stockholder is a person who, together with
affiliates and associates, owns, or within three years, did own, 15% or more of
our voting stock. The statute could have the effect of delaying, deferring or
preventing a change of control of us.

   Our amended and restated certificate of incorporation will provide that any
action required or permitted to be taken by our stockholders must be effected
by a duly called annual or special meeting of stockholders and may not be
effected by any consent in writing. In addition, our bylaws will provide that
special meetings of our stockholders may be called only by a Co-Chairman of our
board of directors, the Chief Executive Officer or pursuant to a resolution
adopted by a majority of the total number of authorized directors or by the
holders of 50% of our outstanding voting stock.

   Our amended and restated certificate of incorporation also will specify that
our board of directors will be classified into three classes of directors.
Under Delaware law, directors of a corporation with a classified board may be
removed only for cause unless the corporation's certificate of incorporation
provides otherwise. Our amended and restated certificate of incorporation does
not provide otherwise. In addition, our amended and restated certificate of
incorporation specifies that the authorized number of directors may be changed
only by resolution of our board of directors, and it does not include a
provision for cumulative voting for directors. Under cumulative voting, a
minority stockholder holding a sufficient percentage of a class of shares may
be able to ensure the election of one or more directors.

   Our amended and restated certificate of incorporation may only be amended
with the approval of 66 2/3% of our outstanding voting stock and our bylaws may
only be amended either by the board of directors or with the approval of 66
2/3% of our outstanding voting stock. Furthermore, our amended and restated
certificate of incorporation will require the advance notice of stockholders'
nominations for the election of directors and business brought before a meeting
of stockholders. Lastly, our amended and restated certificate of incorporation
will provide that a majority of the directors in office, even if less than a
quorum, are entitled to fill vacancies created by resignation, death,
disqualification, removal or by an increase in the size of the board.

   These provisions of our amended and restated certificate of incorporation
and our bylaws could delay or discourage transactions involving an actual or
potential change of control of us, which includes transactions in which
stockholders might otherwise receive a premium for their shares over then
current prices. In addition, these provisions may limit the ability of
stockholders to remove our current management or approve transactions that may
deem to be in their best interests and, therefore, could adversely affect the
price of our common stock.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is Harris Trust
Company of California.

The Nasdaq Stock Market's National Market Listing

   We have applied for our common stock to be quoted on the Nasdaq National
Market under the symbol "WMUX."

                   U.S. TAX CONSEQUENCES TO NON-U.S. HOLDERS

   The following summary describes the material United States federal income
and estate tax consequences of the ownership of our common stock by a Non-U.S.
Holder, as defined below, as of the date of this prospectus. This discussion
does not address all aspects of United States federal income and estate taxes
and does not deal with foreign, state and local consequences that may be
relevant to Non-U.S. Holders in light of their personal circumstances.
Furthermore, the discussion below is based upon the provisions of the Internal
Revenue Code of 1986, as amended, the "Code", and regulations, rulings and
judicial decisions under the Code. These authorities may be repealed, revoked
or modified so as to result in United States federal income tax consequences
different from those discussed below. Persons considering the purchase,
ownership or disposition of our common stock should consult their own tax
advisors concerning the United States federal income tax consequences in light
of their particular situations as well as any consequences arising under the
laws of any other taxing jurisdiction.

   As used herein, a Non-U.S. Holder is a person other than:

  .  (1) a citizen or resident of the United States,

  .  (2) a corporation or partnership created or organized in or under the
     laws of the United States or any political subdivision,

  .  (3) an estate the income of which is subject to United States federal
     income taxation regardless of its source and

  .  (4) a trust

    .  (a) that is subject to the supervision of a court within the United
       States and the control of one or more United States persons as
       described in section 7701(a)(30) of the Code or

    .  (b) that has a valid election in effect under applicable U.S.
       Treasury regulations to be treated as a United States person.

   If a partnership holds our shares, the tax treatment of a partner will
generally depend on the status of the partner and the activities of the
partnership. If you are a partner of a partnership holding out shares, you
should consult your tax advisors.

Dividends

   Dividends paid to a Non-U.S. Holder of our common stock generally will be
subject to withholding of United States federal income tax at a 30% rate or a
lower rate as may be specified by an applicable income tax treaty. However,
dividends that are effectively connected with the conduct of a trade or
business by the Non-U.S. Holder within the United States and, where a tax
treaty applies, are attributable to a United States permanent establishment of
the Non-U.S. Holder, are not subject to the withholding tax, but instead are
subject to United States federal income tax on a net income basis at applicable
graduated individual or corporate rates. Various certification and disclosure
requirements must be complied with in order for effectively connected income to
be exempt from withholding. Any effectively connected dividends received by a
foreign corporation may, under some circumstances, be subject to an additional
branch profits tax at a 30% rate or a lower rate as may be specified by an
applicable income tax treaty.

   Through December 31, 2000, dividends paid to an address outside the United
States are presumed to be paid to a resident of that country, unless the payer
has knowledge to the contrary, for purposes of the withholding tax discussed
above and, under the current interpretation of United States Treasury
regulations, for

                                       64
<PAGE>

purposes of determining the applicability of a tax treaty rate. However, under
United States Treasury regulations, which we refer to as the Final Regulations,
a Non-U.S. Holder of our common stock who wishes to claim the benefit of an
applicable treaty rate and avoid back-up withholding as discussed below for
dividends paid after December 31, 2000, will be required to satisfy applicable
certification and other requirements.

   A Non-U.S. Holder of our common stock eligible for a reduced rate of United
States withholding tax pursuant to an income tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
Internal Revenue Service, which we refer to as the IRS.

Gain on Disposition of Common Stock

   A Non-U.S. Holder generally will not be subject to United States federal
income tax with respect to gain realized on a sale or other disposition of our
common stock, unless

  .  (1) the gain is effectively connected with a trade or business of the
     Non-U.S. Holder in the United States, and, where a tax treaty applies,
     is attributable to a United States permanent establishment of the Non-
     U.S. Holder,

  .  (2) in the case of a Non-U.S. Holder who is an individual and holds the
     Common Stock as a capital asset, the holder is present in the United
     States for 183 or more days in the taxable year of the sale or other
     disposition and other conditions are met, or

  .  (3) the Company is or has been a "U.S. real property holding
     corporation" for United States federal income tax purposes.

   An individual Non-U.S. Holder described in clause (1) above will be subject
to tax on its net gain under regular graduated United States federal income tax
rates. An individual Non-U.S. Holder described in clause (2) above will be
subject to a flat 30% tax on the relevant gain derived from the sale, which may
be offset by United States source capital losses, even though the individual is
not considered a resident of the United States. If a Non-U.S. Holder that is a
foreign corporation falls under clause (1) above, it will be subject to tax on
its net gain under regular graduated United States federal income tax rates
and, in addition, may be subject to the branch profits tax equal to 30% of its
effectively connected earnings and profits within the meaning of the Code for
the taxable year, as adjusted for some items, unless it qualifies for a lower
rate under an applicable income tax treaty.

   We believe we are not and do not anticipate becoming a U.S. real property
holding corporation for United States federal income tax purposes.

   Special rules may apply to some Non-U.S. Holders, such as controlled foreign
corporations, passive foreign investment companies, foreign personal holding
companies and corporations that accumulate earnings to avoid U.S. federal
income tax that are subject to special treatment under the Code. These entities
should consult their own tax advisors to determine the U.S. federal, state,
local and other tax consequences that may be relevant to them.

Federal Estate Tax

   Common stock held by an individual that is not a citizen or resident of the
United States, as specially defined for U.S. federal estate tax purposes, at
the time of death will be included in the holder's gross estate for United
States federal estate tax purposes, unless an applicable estate tax treaty
provides otherwise.


                                       65
<PAGE>

Information Reporting and Backup Withholding

   We must report annually to the IRS and to each Non-U.S. Holder the amount of
dividends paid to the holder and the tax withheld with respect any dividends,
regardless of whether withholding was required. Copies of the information
returns reporting the dividends and withholding may also be made available to
the tax authorities in the country in which the Non-U.S. Holder resides under
the provisions of an applicable income tax treaty.

   Under current law, backup withholding at the rate of 31% generally will not
apply to dividends paid to a Non-U.S. Holder at an address outside the United
States unless the payer has knowledge that the payee is a U.S. person. Under
the Final Regulations, however, a Non-U.S. Holder will be subject to back-up
withholding unless applicable certification requirements are met.

   Payment of the proceeds of a sale of our common stock within the United
States or conducted through U.S. related financial intermediaries is subject to
both backup withholding and information reporting unless the beneficial owner
certifies under penalties of perjury that it is a Non-U.S. Holder and the payor
does not have actual knowledge that the beneficial owner is a United States
person or the holder otherwise establishes an exemption.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to the offering, there has been no public market for our common stock.
The market price of our common stock could decline if our existing shareholders
sell large numbers of shares of our common stock in the public market or if
investors perceive that sales of large numbers of shares of our common stock
could occur. These factors could make it more difficult for us to raise funds
through future offerings of our common stock.

   Upon completion of the offering, there will be     shares of common stock
outstanding, or     shares if the underwriters exercise their over-allotment
option in full, assuming no exercise of outstanding options or warrants after
the date of this prospectus. Of these shares,    shares sold in the offering,
or     shares if the underwriters exercise their over-allotment option in full,
will be freely tradeable without restriction under the Securities Act except
for any shares purchased by our affiliates as defined in Rule 144 under the
Securities Act. The remaining 42,562,123 shares are restricted securities
within the meaning of Rule 144. The restricted securities may not be sold
unless they are registered under the Securities Act or are sold under an
exemption from registration, such as the exemption provided by Rule 144.

   We, our officers and directors and other stockholders have agreed that, for
a period of 180 days from the date of this prospectus, we will not, without the
prior written consent of Salomon Smith Barney Inc., dispose of or hedge any
shares of our common stock or any securities convertible into, or exercisable
or exchangeable for, shares of our common stock. Salomon Smith Barney Inc., in
its sole discretion, may release any of the securities subject to these 180-day
lock-up agreements at any time without notice.

   The restrictions described in the previous paragraph do not apply to:

  .  the sale of shares of common stock to the underwriters in connection
     with the offering;

  .  the automatic conversion of our shares of Class B common stock into
     shares of Class A common stock;

  .  the issuance of shares of Class A common stock to WMC Holding Corp. in
     exchange for shares of Class B common stock in connection with their
     reorganization as described under "Principal Shareholders;" and

  .  the distribution of shares of our common stock owned by WMC Holding
     Corp. after it converts to a limited liability company to its members,
     provided that the members agree to be bound by the same restrictions set
     forth in the previous paragraph.

   Glenayre, which currently owns 2,045,000 shares of our common stock has
entered into an agreement with us in which they have agreed that, until
November 1, 2001, they will not transfer any shares of our common stock, other
than in a registered offering of our common stock.

   In addition, as of March 31, 2000, there were outstanding options to
purchase 4,578,227 shares of common stock and warrants to purchase 4,370,000
shares of common stock.

   Pursuant to Mr. Zakin's employment and co-investment agreement and to Mr.
Seedman's co-investment agreement, Messrs. Zakin and Seedman have both agreed
to provisions restricting the transferability of their shares of our common
stock and warrants. For a more complete description of these restrictions, see
"Material Relationships and Related Transactions--Co-Investment Agreements."

   Rule 144. In general, beginning 90 days after the date of this prospectus
any person, or persons whose shares are aggregated, who has beneficially owned
shares for at least one year, including persons who are

                                       67
<PAGE>

affiliates, is entitled under Rule 144 under the Securities Act to sell, within
any three-month period, a number of shares that does not exceed the greater of:

  .  1% of the then-outstanding shares of our common stock, which will equal
     approximately     shares immediately after the offering; and

  .  the average weekly trading volume in our common stock during the four
     calendar weeks immediately preceding the date on which the seller files
     a notice of the sale on Form 144 with the Commission.

   Requirements relating to notice, manner of sale and the availability of
current public information about us must also be met for sales under Rule 144.

   Rule 144(k). A person, or persons whose shares are aggregated, who is not
and has not been our affiliate at any time during the three months immediately
preceding a sale of shares of our common stock, and who has beneficially owned
the shares proposed to be sold for at least two years, including the holding
period of any prior owner other than an affiliate, would be entitled to sell
the shares under Rule 144(k) under the Securities Act without regard to the
volume limitations, notice requirements and other conditions of Rule 144.

   Rule 701. In general, subject to the restrictions contained in the
stockholder's agreements, each of our directors, officers, employees,
consultants or advisors who purchased shares from us before the date of this
prospectus in connection with a compensatory share plan or other written
agreement would be eligible to sell those shares under Rule 701 under the
Securities Act in the public market 90 days after the date of this prospectus
in reliance on Rule 144, but without complying with all of the restrictions of
Rule 144, such as the holding period. In addition, Rule 701 will apply to
shares of common stock we issue upon the exercise of the options we granted
before the effective date of the offering.

   We intend to file, after the effective date of the offering, a registration
statement on Form S-8 to register up to     shares of our common stock reserved
for issuance under our stock plans. The registration statement will become
effective automatically upon filing. After the registration statement has been
filed, shares issued under our stock plans may be sold in the open market,
unless the sale is limited by the provisions of Rule 144 applicable to our
affiliates, the lock-up agreements, the stockholder's agreements or other
agreements restricting transferability.

   For a description of the registration rights of our stockholders, see
"Description of Capital Stock--Registration Rights."

   Subject to the terms and conditions stated in the underwriting agreement

purchase, and we have agreed to sell to each underwriter, the number of shares
of our common stock set forth opposite the name of each underwriter.

</TABLE>

   The underwriting agreement provides that the obligations of the underwriters
to purchase the shares included in the offering are subject to approval of
various legal matters by counsel and to other conditions. The underwriters are
obligated to purchase all the shares, other than those covered by the over-
allotment option described below, if they purchase any of the shares.

   The underwriters, for whom Salomon Smith Barney Inc., Lehman Brothers Inc.
and CIBC World Markets Corp. are acting as representatives, propose to offer
some of the shares directly to the public at the public offering price set
forth on the cover page of this prospectus and some of the shares to various
dealers at the public offering price less a concession not in excess of $   per
share. The underwriters may allow, and the dealers may reallow, a concession
not in excess of $   per share on sales to other dealers. If all the shares are
not sold at the initial offering price, the representatives may change the
public offering price and other selling terms. The representatives have advised
us that the underwriters do not intend to confirm any sales to any accounts
over which they exercise discretionary authority.

   We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to     additional shares of our
common stock at the public offering price less the underwriting discount. The
underwriters may exercise this option solely for the purpose of covering over-
allotments, if any, in connection with this offering. To the extent this option
is exercised, each underwriter will be obligated, subject to various
conditions, to purchase a number of additional shares approximately
proportionate to its initial purchase commitment.

   At our request, the underwriters will reserve up to     shares of our common
stock to be sold, at the initial public offering price, to our directors,
officers and employees, as well as to some of our customers and suppliers and
individuals associated or affiliated with our directors, customers and
suppliers. This directed share program will be administered by Salomon Smith
Barney Inc. The number of shares of common stock available for sale to the
general public will be reduced to the extent these individuals purchase
reserved shares. Any reserved shares which are not so purchased will be offered
by the underwriters to the general public on the same basis as the other shares
offered by this prospectus. We have agreed to indemnify the underwriters
against certain liabilities and expenses, including liabilities under the
Securities Act in connection with sales of the directed shares.

   We, our officers and directors and other stockholders have agreed that, for
a period of 180 days from the date of this prospectus, we will not, without the
prior written consent of Salomon Smith Barney Inc., dispose of or hedge any
shares of our common stock or any securities convertible into, or exercisable
or exchangeable for, shares of our common stock. Salomon Smith Barney Inc., in
its sole discretion, may release any of the securities subject to these 180-day
lock-up agreements at any time without notice.

   The restrictions described in the previous paragraph do not apply to:

  .  the sale of shares of common stock to the underwriters in connection
     with the offering;

                                       69
<PAGE>

  .  the automatic conversion of our shares of Class B common stock into
     shares of Class A common stock;

  .  the issuance of shares of Class A common stock to WMC Holding Corp. in
     exchange for shares of Class B common stock in connection with their
     reorganization as described under "Principal Shareholders;" and

  .  the distribution of shares of our common stock owned by WMC Holding
     Corp. after it converts to be limited liability company to its members,
     provided that the members agree to be bound by the same restrictions set
     forth in the previous paragraph.

   Prior to this offering, there has been no public market for our common
stock. Consequently, the initial offering price for the shares was determined
by negotiations between us and the representatives. Among the factors
considered in determining the initial public offering price were:

  .  our record of operation;

  .  our current financial condition;

  .  our future prospects;

  .  our markets;

  .  the economic conditions in and future prospects for the industry in
     which we compete;

  .  our management; and

  .  currently prevailing general conditions in the equity securities
     markets, including current market valuations of publicly traded
     companies considered comparable to us.

   We cannot assure you, however, that the prices at which the shares of our
common stock will sell in the public market after this offering will not be
lower than the price at which they are sold by the underwriters or that an
active trading market in our common stock will develop and continue after the
offering.

   We have applied for our common stock to be quoted on the Nasdaq National
Market under the symbol "WMUX."

   The following table shows the underwriting discount and commissions that we
will pay to the underwriters in connection with the offering. These amounts are
shown assuming both no exercise and full exercise of the underwriters' options
to purchase additional shares of common stock.

</TABLE>

   In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell shares of our common stock in the open
market. These transactions may include over-allotment, syndicate covering
transactions and stabilizing transactions. Over-allotment involves syndicate
sales of shares in excess of the number of shares to be purchased by the
underwriters in this offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of shares in the open market
after the distribution has been completed in order to cover syndicate short
positions. Stabilizing transactions consist of certain bids for or purchases of
shares made to prevent or retard a decline in the market price of the shares
while the offering is in progress.


                                       70
<PAGE>

   The underwriters may also impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicated short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

   Any of these activities may cause the price of shares of our common stock to
be higher than it would otherwise be in the open market in the absence of these
transactions. Salomon Smith Barney Inc. may effect these transactions on the
Nasdaq National Market or in the over-the-counter market or otherwise and may
discontinue them at any time.

   We estimate that our total expense for the offering, excluding the
underwriting discount, will be $    million.

   The representatives or their affiliates may in the future perform various
investment banking and advisory services for us from time to time, for which
they will receive customary fees and expenses. The representatives may, from
time to time, engage in transactions with and perform services for us in the
ordinary course of their business.

   Through affiliates of its parent company, Citigroup Inc., Salomon Smith
Barney Inc. holds equity interests in Ripplewood Holdings, L.L.C., which is the
general partner of Ripplewood Partners L.P., as well as limited partnership
interests in Ripplewood Partners L.P.

   We have agreed to indemnify the underwriters against various liabilities,
including liabilities under the Securities Act, or to contribute to payments
the underwriters may be required to make in respect of any of those
liabilities.

                                 LEGAL MATTERS

   The validity of the shares of our common stock offered hereby will be passed
upon for us by Simpson Thacher & Bartlett, New York, New York, and for the
underwriters by Cravath, Swaine & Moore, New York, New York.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Western Multiplex Corporation:

   We have audited the accompanying balance sheets of Western Multiplex
Corporation (a Delaware corporation, formerly known as Glenayre Western
Multiplex Corporation) as of December 31, 1999 and 1998, and the related
statements of income, stockholders' equity and cash flows for each of the three
years in the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. 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 Western Multiplex
Corporation as of December 31, 1999 and 1998, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1999, in conformity with accounting principles generally accepted in the United
States.

                         NOTES TO FINANCIAL STATEMENTS

1.Organization and Operations of the Company

   Western Multiplex Corporation (the "Company") was founded in 1979 in
Sunnyvale, California. In 1992, the Company launched the Lynx broadband
wireless access systems, which are primarily used by wireless operators to
connect their base stations to other base stations and to existing wire line
networks. In 1999, the Company introduced the Tsunami broadband wireless access
systems, which are primarily used by service providers, businesses and other
enterprises to expand or establish private networks carrying Internet traffic
among multiple facilities.

   The Company was acquired by GTI Acquisition Corporation ("GTI") in 1995, a
wholly-owned subsidiary of Glenayre Technologies Inc. ("Glenayre").

   Effective November 1, 1999, a recapitalization of the Company was executed
that included the following transactions, in accordance with the terms of the
Amended and Restated Acquisition Agreement by and among GTI Acquisition Corp.,
Glenayre Technologies, Inc., Western Multiplex Corporation and WMC Holding
Corp. dated September 30, 1999 (the "Agreement"):

  .  The Company borrowed $22.0 million under two term loan arrangements and
     drew down $2.0 million on a $10.0 million revolving credit facility with
     Credit Suisse First Boston.

  .  The Company redeemed 42 million shares of Class B common stock from GTI
     for $21.0 million of the 80 million then outstanding shares.

  .  WMC Holding Corp. ("Purchaser") acquired approximately 36 million shares
     of Class B common stock from GTI, or approximately 94.6% of the
     remaining outstanding shares of the Company, for approximately $16.5
     million.

  .  The Company incurred approximately $0.8 million in financing costs that
     were capitalized and $3.1 million in transaction costs related to the
     equity transactions that were classified as recapitalization costs, a
     non-operating expense in the income statement for 1999.

2.Summary of Significant Accounting Policies

 Use of Estimates in Preparation of Financial Statements

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

 Cash

   Cash consists of cash in bank deposit accounts.

 Revenue Recognition

   Revenue from product and part sales is recognized when all of the following
conditions are met: the product has been shipped, the Company has the right to
invoice the customer at a fixed price, the collection of the receivable is
probable and there are no significant obligations remaining. Provisions to
revenue and cost of revenue are made at the time revenue is recognized for
estimated return and warranty costs, respectively.

   The Company also provides certain services and, rental units to customers to
support their products. Revenue from services and rentals are recognized over
the period for which such services are performed or over the period of the
rental, as applicable. Revenue from such activities was less than 9% of total
revenue for all periods presented.

 Equipment and Leasehold Improvements

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

 Goodwill

   Goodwill represents the excess of cost over the fair market value of net
assets acquired. Goodwill pushed down from the 1995 acquisition of the Company
by GTI totals $22.0 million. The goodwill is being amortized on a straight-line
basis over its estimated useful life of 30 years, or $0.7 million per year. The
carrying amount of goodwill would be reviewed if facts and circumstances
suggest that it may be impaired. If the review indicates that goodwill would
not be recoverable, as determined based on the expected future undiscounted
cash flows of the Company over the remaining amortization period, the carrying
amount of the goodwill would be reduced by the estimated shortfall. No such
writedowns of goodwill have been recorded by the Company in any of the periods
presented.

 Segment Reporting

   In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information" (SFAS No.
131). SFAS No. 131 establishes standards for disclosures about operating
segments, products and services, geographic areas and major customers. The
Company is organized and operates as one operating segment: providing wireless
access products. Revenues by geographic area are attributed to the country from
which the sale is made. To date, all of the Company's transactions have
originated in one geographic location, the United States, even though many of
the Company's customers may operate in foreign as well as domestic markets.

 Major Customers

   One customer accounted for 19% of total revenue in 1999. No other customers
accounted for more than 10% of total revenue in 1999, 1998 or 1997.

 Research and Development

   Research and development costs are expensed as incurred and consist
primarily of payroll costs, other direct expenses and overhead. During a
portion of 1997 and 1998, a Glenayre affiliate provided to the Company certain
research and development resources to assist in product development (see Note
9).

 Earnings Per Share of Common Stock

   Basic and diluted net income per share are presented in conformity with
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS
No. 128). Basic earnings per share under SFAS 128 were computed using the
weighted average number of shares outstanding of 73,000,000 in 1999, 80,000,000
in 1998 and 1997. Diluted earnings per share is determined in the same manner
as basic earnings per share except that the number of shares is increased
assuming dilutive stock options and warrants using the treasury stock method.
For 1999, the treasury stock method resulted in no dilutive securities and,
accordingly basic and dilutive earnings per share were the same. The Company
granted 2,660,000 and 684,000 contingently exercisable warrants and options,
respectively, in 1999 which were not included in the weighted average number of
shares outstanding for the calculation of diluted earnings per share.

 Recent Accounting Pronouncement

   In June 1998, the Financial Accounting Standards Board issued Statement No.
133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS No.
133), which establishes accounting and reporting standards for derivative
instruments and hedging activities. The statement requires recognition of all
derivatives at fair value in the financial statements. FASB Statement No. 137,
"Accounting for Derivative Instruments and Hedging Activities--Deferral of the
Effective Date of FASB Statement No. 133," an amendment of FASB Statement No.
133, defers implementation of SFAS No. 133 until fiscal years beginning after
June 15, 2000. To date, the Company has not entered into any derivative
financial instrument contracts. Thus, the Company anticipates that SFAS No. 133
will not have a material impact on its financial statements.

</TABLE>

   The credit agreement also included a $10 million revolving credit facility
maturing in 2002. Interest rates for the borrowings under the revolving credit
facility are at LIBOR plus 2.5% or prime plus 1.5%, as periodically elected by
the Company. At December 31, 1999, there were $2.0 million of borrowings
outstanding under the agreement. The weighted average interest rate on the
revolving line of credit for the two months outstanding in 1999 was 8.5%.

   The term notes and revolving credit facility are secured by substantially
all of the assets of the Company. The loans also include certain financial
covenants, as follows: maximum leverage of no more than 4.5 for fiscal 2000
declining to 3.5 for fiscal 2001 and thereafter; minimum interest coverage
ratio of 2.5 for fiscal 2000 increasing to 3.5 for fiscal 2002 and thereafter;
minimum fixed charge ratio 1.05 through fiscal 2001 increasing to 1.10
thereafter; minimum EBITDA of $5.5 million through fiscal 2001 increasing to

 Employment Agreements and Change of Control Provisions

   The Company has entered into employment agreements with six of its officers
to provide for payments of their base salaries for a period of up to twelve
months plus bonuses in the event employment is terminated without cause or if
the employer terminates employment with good reason, as defined. A change of
control does not qualify as a good reason for terminating employment. Officers'
annual salaries range from approximately $50,000 to $175,000.

   In addition, in the event of a change of control, all outstanding options
become fully vested and exercisable immediately prior to the change of control
for one of the officers.

7.Income Taxes

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

December 31, 1999 and 1998 are as follows:

   Prior to the recapitalization, the Company had a tax sharing agreement with
Glenayre. The principal provisions of the method by which the consolidated
amount of current and deferred tax expense was allocated to members of the
group (including the Company) were based on the results of each member as if
each were a stand-alone entity. The Company had a payable to Glenayre as of
December 31, 1998 for $1.7 million related to Federal and state income taxes,
which was effectively remitted to Glenayre at the date of the recapitalization.

   The Company intends to make a tax election to treat the share purchase by
WMC Holding Corp. as an asset purchase for Federal income taxes in accordance
with the terms of the Agreement. As a result of the recapitalization, the
Company recorded a deferred tax asset of approximately $3.9 million with a
corresponding increase to paid-in capital.

8.Stockholders' Equity

 Common Stock

   The Company's common stock consists of Class A and Class B common stock.
Holders of Class A common stock are entitled to one vote per share; holders of
Class B common stock are entitled to ten votes per share. Each share of Class B
common stock is convertible into one share of Class A common stock at the
election of the shareholder or automatically in the event of an initial public
offering of the Company. As of December 31, 1999, there were no shares of Class
A common stock issued or outstanding.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   In conjunction with the recapitalization transaction discussed in Note 1,
the Company repurchased 42,000,000 shares of Class B common stock for $21.0
million from Glenayre. The repurchased shares are held as treasury shares as of
December 31, 1999.

 Warrants

   In connection with the recapitalization discussed in Note 1, the Company
issued 4,370,000 warrants to a holding company, owned by the CEO of the
Company, and a trust, of which a director of the Company is trustee and
beneficiary. Each new warrant is convertible into one share of Class A common
stock of the Company at an exercise price of $.50 per share. The warrants
expire on the tenth anniversary from date of issuance. Of the total warrants
issued, 1,710,000 are exercisable at any time prior to the expiration; 760,000
are exercisable in the event of a qualifying triggering event, including an
initial public offering or sale of the Company for an amount exceeding five
times the exercise price in years one through three after the recapitalization,
increasing to approximately seventy times exercise price in year eight;
1,900,000 exercisable in the event of a qualifying triggering event for an
amount exceeding ten times the exercise price in years one to three following
the recapitalization, increasing to four hundred times the exercise price in
year eight.

 Stock Split

   In connection with the recapitalization transaction discussed in Note 1, the
Company increased the number of authorized shares for Class A common stock and
Class B common stock to 100,000,000 common shares each and effected an 80,000-
for-1 stock split of the then 1,000 outstanding Class B common shares. All
share and per share amounts have been restated to retroactively reflect this
stock split for all periods presented.

 1999 Stock Incentive Plan

   In November 1999, the Company adopted the 1999 Stock Incentive Plan (the
"1999 Plan") for key employees, officers, directors, and consultants. The
Company has reserved for issuance 6,000,000 shares of Class A common stock
under the 1999 Plan. The type of awards that may be made under the 1999 Plan
are incentive stock options, non-qualified options, stock appreciation rights,
and other stock-based awards.

   The exercise price for stock options may not be less than 100% of the fair
market value of the Company's common stock on the date of the grant (110% for
any option granted to any stockholder who owns more than 10% of the total
combined voting power of all classes of stock of the Company or its parent or
subsidiary corporation), as determined by the Compensation Committee. An option
may not vest at less than 20% per year over five years, as determined by the
Compensation Committee.

   During November 1999, the Company granted 2,688,000 options to employees
with an exercise price of $.50 per share and a three year vesting period. As of
December 31, 1999, all of the options granted remained outstanding, none of the
options were exercisable and the weighted average useful life was approximately
9.9 years. The Company also granted to employees approximately 684,000 options
that become exercisable in the event of an initial public offering of the
Company. As of December 31, 1999, all of the options granted remained
outstanding, none of the options were exercisable and the weighted average
useful life was approximately 9.9 years.

   The Company follows the provisions of SFAS No. 123, which calls for
companies to measure employee stock compensation expense based on the fair
value method of accounting. As allowed by SFAS No. 123, the Company elected the
continued use of APB Opinion No. 25, with pro forma disclosure of net loss
determined as if the fair value method had been applied in measuring
compensation cost. Had compensation cost for the

Company's stock based compensation awards been determined under the fair value
method consistent with SFAS No. 123, the Company's net income would have
decreased by $369,000 for 1999. Basic and diluted earnings per share would
decrease to $.01 per share for 1999. The fair value of the options was
estimated on the date of grant using the Black-Scholes option valuation model
assuming: risk-free interest rate of 6.07%, average expected life of option of
4 years, dividend yield of 0% and volatility of 0.01%.

9.Related Party Transactions

   The Company was a wholly-owned subsidiary of GTI from April 25, 1995 through
October 31, 1999. Over that period, a variety of costs were incurred by GTI and
its affiliates on behalf of the Company. The costs directly attributable to the
Company have been charged to the Company in the period such costs were incurred
and included in the accompanying income statements. In addition to those
charges, certain other indirect costs were incurred by GTI and its affiliates,
as follows:

  .Beginning in 1997 through February 1998, the Company and a GTI affiliate
     jointly developed a product. The resulting technology was jointly shared
     by both entities upon completion. Glenayre's estimated labor and
     materials costs during 1997 and 1998 were approximately $67,000 and
     $639,000, respectively. The costs incurred by the affiliate were not
     charged to the Company and, accordingly, are not reflected in the
     accompanying income statement.

  .Glenayre and affiliates shared certain services to assist the Company in
     international sales, marketing and customer support services. The
     estimated costs of such services were approximately $20,000, $485,000
     and $896,000 for 1999, 1998 and 1997, respectively. These costs were not
     charged to the Company and, accordingly, are not reflected in the
     accompanying income statement.

  .  Glenayre and affiliates have provided or incurred certain other costs
     for various administrative services through the date of the
     recapitalization, all of which may not have been allocated to or
     included in the financial statements of the Company. Administrative
     services included, preparation of certain tax returns, employee benefits
     planning and administration, limited general accounting and limited
     legal services.

   During 1998 and a portion of 1999, the Company transferred cash to Glenayre.
These transfers were recorded by the Company as related party accounts
receivable. Because the account receivable from Glenayre was ultimately
forgiven as part of the recapitalization transaction in 1999, the net
receivable from Glenayre of $2.0 million as of December 31, 1998 was reflected
as a contra-equity account in the accompanying balance sheet.

   One of the principal investors in WMC Holding Corp. also provides consulting
and management advisory services to the Company beginning November 1, 1999. The
Company was charged 1% of net revenue, or $0.1 million for the two-month period
ended December 31, 1999. The fee has been reflected as a component of general
and administrative expenses in the income statement for 1999. Upon the
successful completion of an initial public offering ("IPO") of the Company,
such management fee charges will be terminated prospectively from the effective
date of the IPO. The same investor also charged the Company $1.7 million for
fees and expenses associated with the recapitalization transactions during
1999. These costs, along with the attorneys, accountants and other fees all
totaling $3.1 million, were classified as recapitalization costs, a non-
operating expense in the income statement for 1999.

   The Company had a non-interest bearing demand note payable to WMC Holding
Corp. as of December 31, 1999 totaling $1.2 million.

10.Subsequent Events (Unaudited)

 Stock Subscription Agreements

   Beginning in January 2000, WMC Holding Corp. entered into stock subscription
agreements with certain key employees, officers, directors, and consultants of
the Company. As of March 31, 2000, WMC Holding Corp. had issued 3,869,351
shares of common stock. WMC Holding Corp. will use the proceeds of this
offering to buy newly issued shares of the Company on a one for one basis.

 Acquisition of Ubiquity Communication, Inc.

   On March 24, 2000, the Company acquired Ubiquity Communication, Inc.
(Ubiquity), located in Petaluma, California. Ubiquity, is a development stage
company, which designs and develops point-to-multipoint broadband wireless
systems. The Company issued 692,772 shares of Class A common stock in the
acquisition and reserved 137,726 shares for issuance upon the exercise of the
Ubiquity options assumed. The Company granted to certain Ubiquity employees an
additional 350,000 options at an exercise price of $.50 under the 1999 Stock
Incentive Plan. Additionally, certain Ubiquity employees purchased 300,000
shares of WMC Holding Corp. under the Employee Stock Purchase Plan.

   The acquisition was accounted for as a purchase transaction. Purchased
intangibles and goodwill related to the acquisition totaled approximately $6.0
million and will be amortized on a straight-line basis over its estimated
useful life of three years.

Item 14. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnities 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
Registrant's Amended and Restated Certificate of Incorporation (Exhibit 3.1
hereto) and the Registrant's Amended and Restated By-laws (Exhibit 3.2 hereto)
will provide for indemnification of the Registrant's directors, officers,
employees and other agents to the maximum extent permitted by Delaware law. In
addition, the Registrant's Amended and Restated Certificate of Incorporation
will provide that a director of the Registrant will not be personally liable to
the Registrant or the Registrant's stockholders for monetary damages for any
breach of fiduciary duty as a director, except to the extent such a limitation
on liability is not permitted under the Delaware General Corporation Law. The
Registrant has also entered into employment agreements (Exhibits 10.1, 10.3,
10.5, 10.8, 10.10, and 10.12 hereto) with some of its officers and directors
which provide for their indemnification with respect to certain matters. The
Underwriting Agreement (Exhibit 1.1) also will provide for cross-
indemnification among the Registrant and the Underwriters with respect to
certain matters, including matters arising under the Securities Act. The
Registrant has purchased directors' and officers' liability insurance for all
of our directors and executive officers.

Item 15. Recent Sales of Unregistered Securities.

   Since January 1, 1997, the Registrant has issued and sold (without payment
of any selling commission to any person) the following unregistered securities:

     1. On November 1, 1999, the Registrant issued 80,000,000 shares of our
  Class B common stock to GTI Acquisition Corp. in connection with a
  recapitalization. These shares replaced the 1,000 shares of common stock
  held by GTI Acquisition Corp. immediately prior to the recapitalization.


                                      II-1
<PAGE>

     2. On March 24, 2000, the Registrant issued an aggregate of 692,772
  shares of Class A common stock to the shareholders of Ubiquity
  Communications Inc. in connection with the Registrant's acquisition of
  Ubiquity Communications.

   The issuances of the above securities were deemed to be exempt from
registration under the Securities Act in reliance on Section 4(2) of the
Securities Act as transactions by an issuer not involving any public offering.
In addition, the issuances described in Items 4, 5, 7 and 8 above were deemed
exempt from registration under the Securities Act in reliance upon Rule 701
under the Securities Act. 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 were affixed to the share certificates and warrants issued
in such transactions. All recipients had adequate access, through their
relationships with us, to information about Western Multiplex.

Item 17. Undertakings.

   (a) The undersigned Registrant hereby undertakes 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.

   (b) 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.

   (c) The undersigned Registrant hereby undertakes that:

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

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