                               PROSPECTUS SUMMARY

                             Airspan Networks Inc.

   We are a global supplier of wireless communications systems that enable
communications service providers to cost effectively deliver integrated high
speed data and voice services to customers at fixed geographic locations. Our
systems, which are referred to as fixed wireless, use proven, robust technology
that provides wide area coverage, security and resistance to fading. Our
systems can be deployed rapidly and cost effectively, providing an attractive
alternative to copper wire and fiber communications networks. Our products
include software tools that optimize geographic coverage of our systems using
the available spectrum frequencies and provide ongoing network management. To
facilitate the deployment and operation of our systems, we also offer network
installation, training and support services.

   Our systems feature an architecture where a central radio transmitter and
receiver, or base station, provides services to multiple customer sites, known
as a point-to-multipoint system. During 1996, we began shipping our products
which were among the first fixed wireless, point-to-multipoint systems to be
commercially deployed. Our systems have been installed by over 40
communications service providers in approximately 30 countries and are being
tested by numerous other service providers.

   We were originally organized in 1994 as a unit within DSC Communications
Corporation. In January 1998 we created a new corporation that purchased the
Airspan unit from DSC. We have generated significant net losses and negative
cash flow since our formation and expect to continue to do so. We have an
accumulated deficit of $72.1 million as of April 2, 2000.

 The Airspan Solution

   The explosive growth in Internet use is driving the global demand for
reliable high speed access and increased capacity to transmit and receive data,
or bandwidth. This demand, together with global deregulation and competition,
is driving incumbent and alternative communications service providers to offer
integrated high speed data and voice services. In order to address the demand
for integrated high speed reliable data and voice services, our fixed wireless
systems are designed to deliver the following benefits to communications
service providers:

   Integrated Data and Voice Services Platform. Our solutions enable
communications service providers to offer integrated high speed data and voice
services, unlike many other access technologies that are optimized for either
data or voice traffic, but not both.

   Quality of Service and Reliability. Our technology provides wide area
coverage, security and resistance to fading, allowing communications service
providers to offer high quality services with the same levels of reliability as
traditional telephone networks.

   Rapid, Cost Effective Deployment.  Our systems' wide area coverage requires
fewer base stations, allowing faster deployment with lower initial capital
outlays. Communications service providers can quickly begin generating new
subscriber revenues due to the reduced up-front planning and infrastructure
costs and the relative ease of installation of our base stations.

   Flexibility and Expandability. Our systems are highly configurable to
customer requirements for specific spectrum frequencies. The modular design of
our systems allows for expansion as customer capacity requirements increase.

                                       3
<PAGE>


   Comprehensive Implementation and Support Solutions. We offer our customers a
range of software tools that provide system-wide analysis for optimizing
geographic coverage and identifying and solving potential sources of
interference. Our software tools also initiate service for new customers and
provide alarm, maintenance and testing functions.

 The Airspan Strategy

   Our goal is to be the leading provider of fixed wireless systems to
communications service providers. Key elements of our strategy include the
following:

  .  capitalize on existing deployments of our systems to attract new
     customers

  .  extend our strong technology position through continued substantial
     investment in research and development

  .  target key growth market opportunities globally

  .  develop and expand our strategic relationships

  .  expand global sales, marketing and customer support presence

   We are a Washington, USA corporation and our principal executive offices are
located at Cambridge House, Oxford Road, Uxbridge, Middlesex UB8 1UN England.
Our telephone number is + 44 1895 467 100. We have a website located as

                                  RISK FACTORS

   You should carefully consider the risks described below before making a
decision to invest in Airspan.

                         Risks Related To Our Business

We have incurred substantial losses and may not be profitable in the future.

   We have incurred net losses since we became an independent company, and as
of April 2, 2000 we had an accumulated deficit of $72.1 million. Our operating
losses have been due in part to the commitment of significant resources to our
research and development and sales and marketing organizations. We expect to
devote additional resources to these areas and, as a result, will need to
continue increasing our quarterly revenues to achieve and maintain
profitability. We cannot be certain that our revenues will grow at past rates
or that we will achieve sufficient revenues for profitability. If we do achieve
profitability, we cannot be certain that we can sustain or increase
profitability on a quarterly or annual basis in the future.

We have a limited operating history, which makes our future operating results
uncertain.

   We are an early-stage company in the emerging fixed wireless communications
access market. We operated as a unit of DSC Communications Corporation
beginning in 1994 and did not become an independent company until January 1998.
As a result of our limited operating history, we have limited financial data
that you can use to evaluate our business. Accordingly, our prospects must be
considered in light of the risks and difficulties frequently encountered by
companies in the early stage of development, particularly companies in new,
rapidly evolving and highly competitive markets.

   In addition, the historical financial information for the year ended
December 31, 1997 and the one month ended January 25, 1998 that we have
included in this prospectus may not reflect what our results of operations
would have been had we operated as a separate, stand-alone company during those
periods. The information for these periods has been prepared as a statement of
revenues and direct costs and does not include DSC corporate allocations of
certain overhead, general and administrative expenses, interest expense and
income taxes, as it is impracticable to allocate such expenses arbitrarily on a
retroactive basis. Therefore, those periods are not good indications of our
future performance.

Since we have a limited operating history and a significant percentage of our
expenses are fixed and do not vary with revenues, our quarterly operating
results are volatile and difficult to predict, and our stock price could
decline.

   We may not be able to accurately forecast our quarterly revenues since our
customers are not required to purchase a specific number of our products in any
given quarter, which will be further affected if major deployments of our
products do not occur in the quarter we anticipated. As a result, our quarterly
operating results have fluctuated in the past and will likely vary in the
future, which could cause the market price of our common stock to decline.
Other factors that may affect our quarterly operating results include our
ability to react quickly to new competing technologies, products and services
which may cause us to otherwise lose our customers, or if our suppliers and
manufacturers are not able to fulfill our orders and a shortage of key
components leads to a delay in shipping our products. We incur expenses in
significant part based on our expectations of future revenue, and we expect our
operating expense, in particular salaries and lease payments, to be relatively
fixed in the short run. Accordingly, an unanticipated decline in revenue for a
particular quarter could have an immediate negative effect on results for that
quarter. We believe that period-to-period comparisons of our operating results
are not necessarily meaningful. You should not rely on any one quarter as an
indication of future performance.

                                       7
<PAGE>



A loss of one or more of our key customers could cause a significant decrease
in our net revenue.

   We currently derive, and expect to continue to derive, a substantial
percentage of our net sales from fewer than ten customers. For the year ended
December 31, 1999, three customers, Suntel Private Ltd, Aliatel a.s. and
eircom, plc, accounted for 59% of our revenue. In the quarter ended April 2,
2000, three customers, AZ Communications Network, Inc., Suntel Private Ltd.,
and eircom, plc accounted for 82% of our revenue. A number of our customers are
affiliated in that they may have cross investments in each other, which means
we may lose more than one customer at once if one party decided to discontinue
deploying our equipment. The amount of revenue we derive from a specific
customer is likely to vary from period to period, and a major customer in one
period may not produce significant additional revenue in a subsequent period.
We anticipate that our operating results will continue to depend on sales to a
small number of key customers in the foreseeable future. In general our
contracts with our customers involve major deployments which require several
months to fulfill, so our results may depend on the same major customers for
consecutive quarters. Once the contract is fulfilled, that customer may
continue to purchase upgrades or services from us, and possibly new products
but we cannot assure you of such future purchases. It is necessary therefore
for us to continually seek new customers in order to increase our revenue. To
the extent that any major customer terminates its relationship with us, our
revenues could decline significantly.

Our customer contracts vary widely in terms and duration, allow our customers
to terminate and are subject to regulatory approvals.

   Our contracts and purchase orders are separately negotiated with each of our
customers and the terms may vary widely. A majority of our customers may only
execute short-term purchase orders for a single or a few systems at one time
instead of long-term contracts for large scale deployment of our systems. These
purchase orders do not ensure that they will purchase any additional products
beyond that specifically listed in the order.

   Moreover, since we believe that these purchase orders may represent the
early portion of longer term customer programs, we expend significant financial
and personnel resources and expand our operations to be able to fulfill these
programs. If our customers fail to purchase additional products to fulfill
their program as we expect, we may be unable to recover the costs we incurred
and our business could suffer.

   In addition, our contracts are generally non-exclusive and contain
provisions allowing our customers to terminate the agreement without
significant penalties, and some contracts are conditional upon our customer's
ability to receive foreign regulatory approvals. Our contracts also may specify
the achievement of shipment, delivery and installation commitments. We are
generally able to meet these commitments or negotiate extensions with our
customers. However, if we fail to meet these commitments in a timely manner,
our customers may choose to terminate their contract with us or impose monetary
penalties. If our customers fail to obtain the required regulatory approvals in
a timely manner, or elect to terminate their contracts with us, our revenues
would be reduced.

Our sales cycle is typically long and unpredictable.

   Our sales cycle can range from approximately six months to approximately two
years and varies depending on the customer. The length of the sales cycle with
a particular customer is influenced by a number of factors, including:

  .  the particular communications market that the customer serves

  .  the testing requirements imposed by the customer on our systems

  .  the customer's experience with sophisticated communications equipment
     including fixed wireless technology

                                       8
<PAGE>

  .  the cost of purchasing our systems, including the cost of converting to
     our products from previously installed equipment, which may be
     significant

   Before we receive orders, our customers typically test and evaluate our
products for a period of months or, in some cases, more than a year. In
addition, the emerging and evolving nature of the communication access market
may cause prospective customers to delay their purchase decisions as they
evaluate new technologies or competing technologies or wait for new products or
technologies. As the average order size for our products increases, our
customers' processes for approving purchases could become more complex, leading
to a longer sales cycle. We expect that our sales cycle will continue to be
long and unpredictable. Accordingly it is difficult for us to anticipate the
quarter in which particular sales may occur, to determine product shipment
schedules and provide our manufacturers and suppliers with enough lead time to
ensure that they have sufficient inventory on hand. In addition, our sales
cycle impairs our ability to forecast revenues and control expenses.

Our international operations may be difficult and costly.

   Sales to customers based outside the U.S. have historically accounted for a
substantial majority of our revenues. In 1999, our international sales
accounted for 96% of our total revenue with sales to customers in Asia Pacific,
particularly Sri Lanka and the Philippines, accounting for 39.5% and Europe,
particularly Ireland and the Czech Republic, accounting for 41.3%. Our
international sales for the quarter ended April 2, 2000 accounted for 98% of
our total revenue with sales to customers in Asia Pacific, particularly Sri
Lanka and the Philippines, accounting for 72.3% and Europe, particularly
Ireland and the Czech Republic, accounting for 23.7%. We are a U.K. based
operation with primarily international sales, which exposes us to risks
associated with international operations including:

  .  longer payment cycles, including difficulty in collecting accounts
     receivable and timing delays associated with collection

  .  tariffs, duties, price controls or other restrictions on foreign
     currencies or trade barriers imposed by foreign countries and
     fluctuations in currency exchange rates

  .  import or export licensing and product certification requirements

  .  seasonal reductions in business activity in some parts of the world

  .  unexpected changes in regulatory requirements

  .  difficulties and costs of staffing and managing foreign operations

  .  political and economic instability, including the impact of economic
     recessions, specifically recently in Asia

  .  limited ability to enforce agreements, intellectual property and other
     rights in some foreign countries

  .  higher levels of regulation relating to the telecommunications industry

   In addition, changes in foreign currency exchange rates also affect our
revenue. See "Fluctuations in the values of foreign currencies could have a
negative impact on our profitability."

We may not be able to expand our sales and distribution capabilities, which
would harm our ability to generate revenue.

   We believe that our future success depends upon our ability to expand our
direct and indirect sales operations, including establishing relationships with
international distributors. We cannot be certain that we will be successful in
these efforts. In addition, our distributors may not devote adequate resources
to marketing, selling and supporting our products. If we fail to expand these
sales channels, our business will be seriously harmed.

Our results of operations could be negatively affected if we are unable to
manage our rapid growth effectively.

   We have experienced a period of rapid growth and expansion that has strained
our resources. Since we became an independent company, the number of our
employees, including contract personnel, increased from

                                       9
<PAGE>

74 to 217 as of March 31, 2000. We intend to continue to expand rapidly. In
order to manage growth effectively, we must continue to develop and expand our
operational systems, procedures and controls. A failure to do so would impair
our ability to accurately forecast sales demand, manage our product inventory
and record and report financial and management information on a timely and
accurate basis. Our inability to manage growth effectively could seriously harm
our business.

Competition from larger, better capitalized or emerging competitors for our
products could result in price reductions, reduced gross margins and loss of
market share.

   We compete in a new, rapidly evolving and highly competitive and fragmented
market. We compete with companies that are producing fixed wireless
communications access systems, satellite access systems, cable access systems
and other new entrants to this industry, as well as traditional communications
companies.

   We expect competition to persist and intensify in the future. In the
particular frequencies where we operate, we compete directly with ECI and
Lucent, as well as smaller start-up companies. We compete indirectly with a
number of large telecommunication equipment suppliers such as Alcatel,
Ericsson, Hughes, and Nortel. In addition, our technology competes with other
high speed solutions, such as digital subscriber lines, optical fiber cable,
cable modems and high speed leased lines and satellite technologies.

   Many of our competitors are substantially larger than we are and have
significantly greater financial, sales and marketing, technical, manufacturing
and other resources and more established distribution channels. These
competitors may be able to respond more rapidly to new or emerging technologies
and changes in customer requirements or to devote greater resources to the
development, promotion, sale and financing of their products than we can.
Furthermore, some of our competitors may make strategic acquisitions or
establish cooperative relationships among themselves or with third parties to
increase their ability to gain customer market share rapidly. These competitors
may enter our existing or future markets with systems that may be less
expensive, provide higher performance or contain additional features.

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

Our dependence on key suppliers and one manufacturer may result in product
delivery delays.

   Some of the key components of our products are purchased from single
vendors, including printed circuit boards from Flextronics International Sweden
AB, cabinets from Ripley Engineering Limited, electronic connector panels from
Sanmina (Ireland) Limited and electric power amplifiers from Amplidyne Inc.,
for which alternative sources are generally not readily available. If our
vendors fail to supply us with components because they do not have them in
stock when we need them, they reduce or eliminate their manufacturing capacity
for these components or they enter into exclusive relationships with other
parties which prevents them from selling to us, we could experience significant
delays in shipping our products while we seek other sources, which may result
in our customers claiming damages. At times we have been forced to purchase
these components from distributors instead of from the manufacturers, which
significantly increases our costs. We do not have long-term contracts with most
of these suppliers. Instead, we execute purchase orders approximately three to
six months in advance of when we believe we may need the components. These
purchase orders are non-exclusive, and we are generally not required to
purchase any minimum volume of components from any of these suppliers. Since we
do not have long-term contracts with these suppliers, they may terminate our
relationship with up to four months' notice.

   In addition, we outsource most of our manufacturing processes to
Flextronics. Flextronics relies on our forecasts of future orders to make
purchasing and manufacturing decisions. We provide them with forecasts on a
biweekly basis. If our forecast turns out to be inaccurate, it may lead either
to excess inventory that would increase our costs or a shortage of components
that would delay shipments of our systems. Our contract with

                                       10
<PAGE>


Flextronics is non-exclusive and may be terminated with four months' notice by
either party without significant penalty. Other than agreeing to purchase the
materials we request in the forecasts, we do not have any agreements with them
to purchase any minimum volume. It is possible that our major competitors may
enter into contracts with Flextronics.

   Our products incorporate software developed and maintained by third parties.
We depend on these third parties to deliver, support and enhance their
software. The failure of these third parties to do so could seriously harm our
business.

Our ability to attract, train and retain qualified employees is crucial to
increase our revenue and future growth.

   The design and development of fixed wireless communications access systems
is complex and requires highly trained professional software, hardware and
radio frequency engineers and customer support personnel. Our business strategy
of developing and delivering sophisticated products and providing our customers
with the appropriate levels of technical support will suffer if we do not have
the skilled personnel working for us. In addition, our future growth also
depends upon our ability to expand our sales and marketing operations in order
to seek new customers, maintain key customer relationships and increase market
awareness of our products. Even if we are able to hire these personnel, we will
need to train them, and they will need time to become fully productive.
Competition for skilled personnel is intense, especially in the London, England
area where we maintain our primary operations. The inability to attract or
retain qualified personnel in the future or delays in hiring required
personnel, particularly engineers and sales and marketing professionals, may
hinder our ability to keep up with new technologies or continue to increase our
customer base.

The loss of Eric Stonestrom or any of our other executive officers could impair
our ability to implement our business plan successfully.

   We believe that our ability to implement our business strategy and our
future success depends on the continued employment of our senior management
team, in particular our president and chief executive officer, Eric Stonestrom.
Our senior management team, who have extensive experience in our industry and
are vital to maintaining some of our major customer relationships, would be
very difficult to replace. The loss of the technical knowledge and management
and industry expertise of these key employees could make it difficult for us to
execute our business plan effectively, could result in delays in new products
being developed, lost customers and diversion of resources while we seek
replacements.

If we are not able to implement a program to reduce costs over time, introduce
new products or increase sales volume, our gross margin may decline.

   We expect the average selling prices of our products to decline due to a
number of factors, including competitive pricing pressures, rapid technological
change and volume sales discounts. Accordingly, to maintain or increase our
gross margin, we must develop and introduce new products or product
enhancements with higher gross margins and implement cost reductions.

   If our average selling prices continue to decline and we are not able to
maintain or increase our gross margin, our results of operations could be
harmed.

We may not have adequate protection for our intellectual property, which may
make it easier for others to sell competing products at lower prices.

   Our success depends in part on proprietary technology. We rely on a
combination of patent, copyright, trademark and trade secret laws and
contractual restrictions on disclosure to protect our intellectual property
rights. Despite our efforts to protect our proprietary rights, we cannot be
certain that the steps we have taken

                                       11
<PAGE>

will prevent misappropriation of our technology, and we may not be able to
detect unauthorized use or take appropriate steps to enforce our intellectual
property rights. The laws of some foreign countries do not protect our
proprietary rights to the same extent as the laws of the U.S. and the U.K., and
we may encounter substantial infringement problems in those countries. In
addition, we do not file for patent protection in every country where we
conduct business. If we fail to adequately protect our intellectual property
rights, or fail to do so under applicable law, it would be easier for our
competitors to copy our products and sell competing products at lower prices,
which would harm our business.

Our products may infringe on the intellectual property rights of third parties,
which may result in lawsuits and prohibit us from selling our products.

   Third parties could assert exclusive patent, copyright, trademark and other
intellectual property infringement claims against the technologies that are
important to us. In addition, third parties may assert claims, or initiate
litigation against us, or our manufacturers, suppliers or customers with
respect to existing or future products, trademarks or other proprietary rights.
There is a substantial risk of litigation regarding intellectual property
rights in our industry. Any claims against us or customers that we indemnify
against intellectual property claims, with or without merit, may:

  .  be time-consuming, costly to defend and harm our reputation

  .  divert management's attention and resources

  .  cause delays in the delivery of our products

  .  require the payment of money damages

  .  result in an injunction, which would prohibit us from using these
     technologies and require us to stop shipping our systems until they
     could be, if possible, redesigned

  .  require us to enter into license or royalty agreements, which may not be
     available on acceptable terms or require payment of substantial sums

Fluctuations in the values of foreign currencies could have a negative impact
on our profitability.

   Although 87% of our sales in 1999 were denominated in U.S. dollars, we incur
most of our expenses in British pounds and a majority of our cost of goods sold
in Swedish krona. We expect these percentages to fluctuate over time. While we
recently commenced currency hedging activities to limit the risks of exchange
rate fluctuations, fluctuations in the value of foreign currencies could still
have a negative impact on the profitability of our global operations and our
business. The value of foreign currencies may also make our products more
expensive than local products.

A material defect in our products could seriously harm our credibility and harm
our business.

   We have detected and are likely to continue to detect errors and product
defects in connection with new product releases and product upgrades. In the
past, some of our products have contained defects that have to date delayed the
commencement of service but have not materially affected the operation, planned
scale or planned functionality of the networks. We may experience future
defects that materially affect customer networks which may adversely affect our
ability to sell our systems, cause us to incur significant warranty and repair
costs and harm our credibility with our customers. Fixed wireless devices are
highly complex and frequently contain undetected software or hardware errors
when first introduced or as new versions are released. If our hardware or
software contains undetected errors, we could experience:

  .  delayed or lost revenues and market share due to adverse customer
     reactions

  .  higher costs and expenses due to the need to provide additional products
     and services to a customer at a reduced charge or at no charge

  .  claims for substantial damages against us, regardless of our
     responsibility for any failure, which may lead to increased insurance
     costs

                                       12
<PAGE>

  .  negative publicity regarding us and our products, which could adversely
     affect our ability to attract new customers

  .  diversion of management and development time and resources

   Our general liability insurance coverage may not continue to be available on
reasonable terms or in sufficient amounts to cover one or more large claims, or
our insurer may disclaim coverage as to any future claim. The successful
assertion of any large claim against us could adversely affect our business.

If there is a problem in one of our networks, we may have difficulty
identifying the source of the problem.

   Our products must successfully integrate with products from other companies.
When problems occur in a network, it may be difficult to identify the source of
the problem. Although a third-party's product may be the source of hardware or
software errors in our network, our customers may hold us responsible. We may
not be able to respond quickly to correct these problems, which may result in
the loss of future sales and harm to our reputation. In addition, we may be
forced to incur significant expenses.

Because our executive office and our executive officers are in the United
Kingdom, you may not be able to enforce judgments against us that are obtained
in U.S. courts.

   Since our executive office is located in Middlesex, England, our executive
officers reside outside the U.S. and a portion of our assets are located
outside the U.S. As a result, it may be difficult or impossible for investors
to effect service of process upon such persons within the U.S. or to enforce
against such persons judgments obtained in the U.S. courts, including judgments
predicated upon the civil liability provisions of the federal securities laws
of the U.S.

                         Risks Related To Our Industry

Fixed wireless systems may not achieve widespread acceptance, which could cause
our business to fail.

   The fixed wireless market is relatively new. Our ability to sell and deploy
our systems in the future depends on commercial acceptance of fixed wireless
technology as a communications system. In particular, if alternative
technologies, including wireline, cable and satellite approaches, achieve a
significantly different cost, performance or deployment profile which makes
them less expensive, more accessible or technologically sophisticated, fixed
wireless systems could be significantly less competitive.

   In order to achieve commercial acceptance, we will need to educate
prospective customers, including large, established communications companies,
governments and government contractors in developing countries, about the
benefits and uses of fixed wireless systems in general and our systems in
particular. If our efforts fail or if fixed wireless systems do not achieve
commercial acceptance, our business could be seriously harmed.

Changes in telecommunications regulation could adversely affect our customers
and may lead to lower sales and may also restrict our business.

   Our customers are subject to extensive regulation as communications service
providers. Changes in legislation or regulation that adversely affect our
existing and potential customers could lead them to spend less on
communications access systems, which would harm our business.

   At present there are few laws or regulations that specifically address our
business of providing communications access equipment. However, future
regulation may include access or settlement charges or tariffs which could
impose economic burdens on us and our customers. We are unable to predict the
impact, if any, that future legislation, judicial decisions or regulations will
have on our business.

                                       13
<PAGE>

The communications systems market is changing rapidly, and failure to
anticipate and react to the rapid change could result in loss of customers or
unnecessary capital expenditure.

   The market for communications systems has been characterized by:

  .  rapid technological developments

  .  evolving industry standards

  .  dramatic changes in the regulatory environment

  .  frequent new product and service introductions

   Our future success depends largely on our ability to enhance our existing
products and services and to introduce new products and services that are based
on leading technologies and that are capable of adapting to changing
technologies, industry standards and customer preferences, in a timely and cost
effective manner.

   New technologies, services or standards could require us to significantly
change our business model, develop new products or provide additional services.
New products and services may be expensive to develop and may result in the
introduction of additional competitors into the marketplace. Furthermore, if
the overall market for communications systems grows slower than anticipated, or
if our products and services fail in any respect to achieve market acceptance,
our revenues would be lower than we anticipate and our business could be
adversely affected.

                         Risks Related to the Offering

Our existing shareholders have voting control over Airspan.

   On completion of this offering, our executive officers and directors and
their affiliates will beneficially own in the aggregate approximately 33.2% of
our outstanding common stock. This percentage will be 32.4% if the underwriters
exercise their over-allotment option in full. As a result, these shareholders
will be able to exercise significant control over all matters requiring
shareholder approval, including the election of directors and approval of
significant corporate transactions, which may have the effect of delaying or
preventing a third party from acquiring control over us.

Our stock price may be volatile after this offering because our shares have not
been publicly traded before this offering.

   Prior to this offering, you could not buy or sell our common stock publicly.
An active trading market for our stock may not develop or be sustained after
this offering. The initial public offering price will be determined by us and
the underwriters based on negotiations concerning the valuation of our common
stock. The public market may not agree with or accept this valuation. The
market price for our common stock is likely to be volatile, which may be caused
by a number of factors, some of which are beyond our control:

  .  variations in our quarterly operating results which are difficult to
     predict

  .  changes in financial estimates or investment recommendations by
     securities analysts relating to our stock based on their perceptions of
     our business

  .  changes in market valuations of similar companies or the
     telecommunications business in general

  .  announcements by us or our competitors of significant contracts,
     acquisitions, strategic partnerships, joint ventures or capital
     commitments which the market may view as unfavorable to us

  .  loss of one of our major customers whom we depend upon to generate
     revenue

  .  the potential for future sales of our common stock

  .  fluctuations in the stock market price and volume of traded shares
     generally, especially fluctuations in the technology sector which tends
     to be volatile

We may need to raise additional capital after this offering and if we are not
able to raise capital on acceptable terms or on a timely basis, we may not be
able to continue our business operations.

   We anticipate that we will continue to experience negative cash flow for at
least the next 36 months following the offering, and may need to raise
additional funds. If we cannot secure needed funds on acceptable terms, we may
not be able to develop or enhance our technologies or products, take advantage
of future opportunities or respond to competitive pressures or unanticipated
cash requirements, or hire and recruit additional personnel, which could
seriously harm our business. If we issue additional equity securities to raise
funds, the ownership percentage of existing shareholders would be reduced. New
investors may demand rights, preferences or privileges senior to those of
existing holders of our common stock.

When we become a public company, we may be the target of securities class
action litigation, which could be costly and time consuming to defend.

   In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of its
securities. Although we are not currently a party to any such class action
litigation as a private company, we may in the future be the target of
litigation since the volatility of the market price of our securities may cause
our investors to lose money. Securities litigation may result in substantial
costs to defend and divert management's attention and resources.

Our articles of incorporation and bylaws and Washington law contain provisions
that could delay or prevent a change of control of Airspan.

   Certain provisions of our articles of incorporation and bylaws and
Washington law may discourage, delay or prevent a merger or acquisition that a
shareholder may consider favorable. These provisions include:

  .  authorizing the board of directors to issue additional common and
     preferred stock

  .  not permitting cumulative voting in the election of directors

  .  limiting the persons who may call special meetings of shareholders

  .  not permitting shareholder action by written consent

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

   We are also subject to certain provisions of Washington law that could
delay, deter or prevent us from entering into an acquisition. Chapter 19 of the
Washington Business Corporation Act prohibits a Washington corporation such as
Airspan from engaging in a business combination with an interested shareholder
unless specific conditions are met.

Substantial future sales of our shares in the public market may cause our stock
price to fall.

   If our shareholders (especially our existing shareholders) sell substantial
amounts of our common stock in the public market after this offering, our stock
price may decline significantly. These sales also might make it more difficult
for us to sell equity securities in the future. All of the shares sold in this
offering will be freely tradable. Substantially all of the remaining shares are
subject to lock-up arrangements between the shareholders and us or the
underwriters. Of the remaining shares of common stock outstanding after this
offering, 27,555,381 will be eligible for sale in the public market 180 days
following the date of the final prospectus. Of these shares, 18,388,849 shares
will be subject to volume limitations under federal securities laws.

   In addition, on the date 180 days following the date of the final
prospectus, approximately 723,481 shares will be subject to vested options.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   Some of the statements under the captions "Prospectus Summary", "Risk
Factors", "Use of Proceeds", "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere in this
prospectus are "forward-looking statements". These statements involve known and
unknown risks and uncertainties, such as our plans, objectives, expectations
and intentions, and other factors that may cause our, or our industry's, actual
results, levels of activity, performance or achievements to be materially
different from any future results, levels of activity, performance or
achievements expressed or implied by the forward-looking statements. These
factors are listed under "Risk Factors" and elsewhere in this prospectus.

   In some cases, you can identify forward-looking statements by terminology
such as "expects", "anticipates", "intends", "may", "should", "plans",
"believes", "seeks", "estimates" or other comparable terminology.

   Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we do not guarantee future results, levels of
activity, performance or achievements. Our actual results and the timing of
certain events could differ materially from those anticipated in these forward-
looking statements. We are under no obligation to update any of the forward-
looking statements after the date of this prospectus to conform these
statements to actual results.

                                USE OF PROCEEDS

   We expect to receive proceeds of approximately $45.0 million from the sale
of 5,000,000 shares of common stock, and an additional $7.0 million from the
sale of 750,000 shares if the underwriters' over-allotment option is exercised
in full, at an assumed initial public offering price of $10.00 per share and
after deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by us.

   We intend to use the net proceeds of this offering primarily for additional
working capital and other general corporate purposes, including in management's
estimation continued investment in research and development between $15 million
and $25 million and sales and marketing expenditures between $10 million and
$20 million. The amounts and timing of these expenditures will vary depending
on a number of factors, including the amount of cash generated by our
operations, competitive and technological developments and the rate of growth,
if any, of our business. While we have no specific plans for any remaining
proceeds, we may also use a portion of the net proceeds to acquire 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 to do so and are not currently engaged in any
negotiations for any acquisition or joint venture.


   Pending the uses described above, we intend to invest the net proceeds in
short-term, interest bearing, investment-grade securities. We cannot predict
whether the proceeds will be invested to yield a favorable return.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our common stock. We
currently intend to retain any future earnings to fund the development and
growth of our business. In addition, pursuant to a loan agreement with a
capital equipment lessor, we cannot pay dividends without such lender's
consent. Accordingly, we do not currently anticipate paying any cash dividends
in the foreseeable future.

This table excludes the following shares as of April 2, 2000:

 .  1,776,851 shares issuable upon exercise of outstanding options at a weighted
   average exercise price of $1.94 per share

 .  an aggregate of 281,090 shares available for future issuance under our stock
   option plan

 .  an aggregate of 249,998 shares of preferred stock issuable upon the exercise
   of 249,998 warrants to purchase preferred stock at an exercise price of
   $1.75 per share; upon the closing of this offering these warrants will
   convert into warrants to purchase 83,333 shares of common stock at an
   exercise price of $5.25 per share

                                    DILUTION

   Our pro forma net tangible book value as of April 2, 2000 was approximately
$54.1 million, or $1.91 per share after giving effect to the conversion of all
of our outstanding preferred stock as of April 2, 2000, and subsequent sales of
578,573 shares of Series C preferred stock at $2.50 per share into common stock
upon the closing of this offering. Pro forma net tangible book value per share
represents the amount of our total tangible assets less total liabilities,
divided by the number of shares of common stock outstanding, after giving
effect to the conversion of all of our outstanding preferred stock as of April
2, 2000, and subsequent sales of 578,573 shares of Series C preferred stock at
$2.50 per share into common stock.

   Dilution per share to new investors represents the difference between the
amount per share paid by purchasers of shares of common stock in this offering
and the pro forma net tangible book value per share of common stock immediately
after the completion of this offering. After giving effect to the sale of the
5,000,000 shares of common stock in this offering at an assumed initial public
offering price of $10.00 per share and after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable
by us, our pro forma net tangible book value at April 2, 2000 would have been
approximately $99.5 million, or $2.98 per share. This represents an immediate
increase in net tangible book value of $1.07 per share to existing shareholders
and an immediate dilution in net tangible book value of $7.02 per share to new
investors of common stock in this offering. The following table illustrates
this dilution on a per share basis:

holders of common stock and by the new investors, before deducting underwriting

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

   The following discussion and analysis should be read in conjunction with our
consolidated financial statements and the related notes included else where in
the prospectus. The financial information for the year ended December 31, 1997
and January 1998 relate to the periods while we were a unit of DSC, which we
refer to as the predecessor business. The information relating to the
predecessor business has been prepared as a statement of revenues and direct
costs and expenses and is not intended to be a complete presentation of the
financial results of operations of the predecessor business. Since our
financial information for the eleven months ended December 31, 1998 is not a
full year, we refer to that period as "fiscal 1998" in the following discussion
and analysis.

Overview

   We are a global supplier of wireless communications systems that enable
communications service providers to cost effectively deliver to customers at
fixed geographic locations integrated high speed data and voice services. We
were originally organized in 1994 as a unit within DSC Communications
Corporation, a telecommunications equipment manufacturer acquired by Alcatel in
1998. DSC began developing fixed wireless access systems in 1992. In January
1998 we created a new corporation that purchased the Airspan unit from DSC for
$25 million, consisting of $15 million of debt payable over three years
beginning February 1, 2001 and 10 million shares of preferred stock. Following
the acquisition of DSC by Alcatel, we redeemed the preferred stock held by DSC
for a cash payment of $10 million. During February 1999 we moved to our own
premises in Uxbridge, U.K.

   We generated revenue of $4.8 million in 1997, $11.5 million in fiscal 1998,
$12.5 million in 1999, and $5.7 million in the quarter ended April 2, 2000. We
have incurred net losses of $16.7 million, $35.6 million, and $29.4 million for
1997, fiscal 1998 and 1999, respectively and we incurred net losses of $7.1
million in the first quarter of 2000. Since becoming an independent company we
have generated significant net losses and negative cash flow since our
formation and expect to continue to do so. We have an accumulated deficit of
$72.1 million as of April 2, 2000.

   We generate revenue from sales of our integrated systems including hardware
and software and from services related to implementation and support
activities. Sales of our systems, primarily our AS4000 systems, constituted 93%
in fiscal 1998 and 89% in 1999. Our sales have been from a relatively small
number of our systems. Following our purchase of the Airspan unit from DSC, we
continued to sell products developed while we were a division of DSC, which we
refer to as our older generation products. In 1998, we introduced products that
assign frequencies to users only when needed, which significantly expanded the
potential number of users per system. We refer to these products, which have
higher margins than our older generation products, as our newer generation
products. Although service revenue does not currently constitute a material
portion of our revenue, we believe services will increase as a percentage of
our revenue. Revenue is recognized when all significant contractual obligations
have been satisfied and the collection of resulting revenues is reasonably
assured. For most product sales, revenue recognition occurs on shipment. For
contracts with nonstandard terms revenue is recognized when these terms have
been satisfied. Revenue from customer service contracts is recognized once the
services have been rendered. Any billings in excess of revenue recognized for
products or services are classified as deferred income or customer advances.

   We sell our products primarily through our direct sales force and, to a
lesser extent, through distribution channels. We have a direct sales presence
in the U.S., U.K., Sweden, Denmark, Poland, Czech Republic, Brazil, the
Philippines, South Korea, Sri Lanka and Canada. We also sell through
independent agents and resellers in markets where we do not have a direct sales
presence and to original equipment manufacturers who may sell our products
under their name. Our sales cycle is typically long and unpredictable and
varies between six months to two years, and often involves extensive testing
and evaluation by prospective customers, which makes it difficult for us to
anticipate the quarter in which particular sales may occur.


                                       21
<PAGE>


   In 1999, our international sales accounted for 96% of our total revenue,
while U.S. sales accounted for 4%. Most of the U.S. sales consisted of systems
sold to U.S. customers but were shipped to destinations outside the U.S. In the
future, we expect U.S. sales to increase as a percentage of our total sales. In
1999, our top ten customers accounted for 89% of our revenue. We currently
derive, and expect to continue to derive, a substantial percentage of our
revenue from fewer than ten customers. In the quarter ended April 2, 2000, AZ
Communications Network, Inc., Suntel Private Ltd. and eircom, plc represented
36%, 28% and 17%, respectively, of our revenue. For the year ended December 31,
1999, Suntel Private Ltd., Aliatel a.s. and eircom, plc represented 28%, 18%
and 13%, respectively, of our revenue. For the eleven months ended December 31,
1998, Smart Communications, Aliatel a.s. and Telbank represented 18%, 14% and
14%, respectively, of our revenue. We anticipate that our operating results
will continue to depend on sales to a small number of key customers in the
foreseeable future. The following table identifies the percentage of our sales
by geographic region in the periods identified.

</TABLE>

   Cost of revenue consists of component and material costs, direct labor
costs, warranty costs, royalties, overhead related to manufacturing our
products and customer support costs. Our gross margin is affected by changes in
our product mix because our gross margin on base stations and related equipment
is substantially higher than the gross margin on subscriber terminals. In
addition, our gross margin is affected by changes in the average selling price
of our systems, volume discounts granted to significant customers and the
proportion of total revenue of sales of software which typically carries a
higher gross margin than hardware. We expect the average selling prices of our
products to decline and we intend to continue to implement product cost
reductions and develop and introduce new products or product enhancements to
maintain or increase our gross margins. Further, we expect to derive an
increasing proportion of our revenue from the sale of our integrated systems
through distribution channels. Revenue derived from these sales channels
typically carry a lower gross margin than direct sales.

   Research and development expenses consist primarily of salaries and related
costs for personnel and expenses for design, development and testing facilities
and equipment. These expenses also include costs associated with product
development efforts, including consulting fees and prototyping costs from
initial product concept to manufacture and production. We expect to continue to
make substantial investments in research and development.

   Sales and marketing expenses consist of salaries and related costs for
personnel, sales commissions, consulting fees and expenses for advertising,
travel, technical assistance, trade shows, and promotional and demonstration
materials. We expect to continue to incur substantial expenditures related to
sales and marketing activities including cost associated with the recruitment
of additional sales and marketing personnel and for the expansion of our
distribution channels.

   General and administrative expenses consist of salaries and related expenses
for personnel, professional and consulting fees and other related expenses
including facilities costs. We expect general and administrative expenses to
continue to increase as we add personnel and incur additional costs related to
the anticipated growth of our business and operation as a public company.

   We expect research and development, sales and marketing and general and
administrative expense categories to increase in absolute dollars. However, the
percentage of revenue that each of these categories

                                       22
<PAGE>

represents will vary depending on the rate of our revenue growth and
investments that may be required to support the development of new products and
our penetration of new markets.

   We have recently announced new contracts for the sale of our AS 4000 and
related products and services to Motorola and N-abler. On February 28, 2000, we
announced that we have executed an agreement with Motorola whereby Motorola
will offer our systems as part of its wireless solutions portfolio, opening up
a new sales channel for our products. On April 18, 2000, we announced that N-
abler Communications Inc., an equipment operator for AZ Communications, will
purchase our AS 4000 systems and deploy those systems to large corporate
customers in the Philippines.

   We outsource most of our manufacturing processes to Flextronics
International and expect to continue to use contract manufacturers. We also
purchase some of the key components of our products from single vendors for
which alternative sources are generally not readily available.

Comparison of the Quarter Ended April 2, 2000 to the Quarter Ended April 4,
1999

 Revenue

   Revenue increased 335% from $1.3 million for the quarter ended April 4, 1999
to $5.7 million for the quarter ended April 2, 2000. The growth in revenue has
been due to the increased demand of our newer generation, higher priced
products predominantly from customers located in Asia Pacific and Europe, which
increased 960% and 185%, respectively. Our increase in revenue is due to
volume, rather than price increases.

 Cost of Revenue

   Cost of revenue increased 298% from $0.9 million in the quarter ended April
4, 1999 to $3.5 million in the quarter ended April 2, 2000, resulting from the
substantial increase in revenue. Gross profit as a percentage of revenue
increased from 31.9% for the quarter ended April 4, 1999 to 37.6% for the
quarter ended April 2, 2000. The gross profit improvement reflected primarily
the results of fewer product design changes and, to a lesser extent, increased
volume and introduction of lower priced products, partly offset by lower
average selling prices.

 Research and Development Expenses

   Research and development expenses increased 30.6% from $3.2 million in the
quarter ended April 4, 1999 to $4.2 million in the quarter ended April 2, 2000,
due to increased headcount.

 Sales and Marketing Expenses

   Sales and marketing expenses increased 60.5% from $1.9 million in the
quarter ended April 4, 1999 to $3.1 million in the quarter ended April 2, 2000,
reflecting a higher headcount and the expansion of our sales and marketing
activities. In addition, sales and marketing expenses for the first quarter of
1999 and 2000 included provisions totaling $0.0 million and $0.1 million,
respectively, for potential bad debt expense.

 General and Administrative Expenses

   General and administrative expenses increased 24.6% from $1.8 million in
quarter ended April 4, 1999 to $2.2 million in the quarter ended April 2, 2000,
reflecting a higher headcount.

 Acquired In-process Research and Development and Amortization of Intangibles

   Acquired in-process research and development and amortization of intangibles
expense decreased 55.3% from $0.6 million in the quarter ended April 4, 1999 to
$0.3 million in the quarter ended April 2, 2000, reflecting the full write off
of core/developed technology, purchase contracts and patents.

 Interest and other Income

   Interest and other income increased 183.4% from $0.4 million for the quarter
ended April 4,1999 to $1.1 million in the quarter ended April 2, 2000 and
consisted of interest earned on cash deposits with financial institutions. The
increased interest was from higher cash balances from additional equity
capital. Amounts from interest income were partially offset by interest expense
of $0.3 million and $0.5 million respectively, on predominately outstanding
indebtedness owed to DSC related to the purchase of the company's assets in
January 1998.

 Income Taxes

   We did not record an income tax benefit for the tax losses generated in the
U.K. because we have experienced operating losses since inception. The first
quarter 1999 and 2000 tax provisions relates to U.S. federal income taxes
currently payable primarily attributable to intercompany interest income.

                                       24
<PAGE>


 Net Loss

   Net loss remained essentially unchanged at $7.1 million from first quarter
1999 to first quarter 2000. Increases in revenue and gross profits were offset
by increases in research and development, sales and marketing and general and
administrative expenses.

Comparison of Fiscal Period Ended December 31, 1998 and Year Ended December 31,
1999

 Revenue

   Revenue increased 9% from $11.5 million in fiscal 1998 to $12.5 million in
1999. During 1999, revenue from older generation products decreased
approximately $8.8 million but was more than offset by revenue from sales of
newer generation products to customers located in Asia Pacific and Europe.
Sales to customers in Asia Pacific increased 243% while sales to customers in
the U.S. declined 84%.

 Cost of Revenue

   Cost of revenue decreased 15% from $9.5 million in fiscal 1998 to $8.1
million in 1999, resulting from shipment of lower cost products and a $2.1
million provision for excess inventory for older generation products in fiscal
1998. Gross profit as a percentage of revenue increased from 17.0% during
fiscal 1998 to 35.2% during 1999. Excluding the inventory provision for older
generation products of $2.1 million, gross profits remained constant from
fiscal 1998 to 1999.

 Research and Development Expenses

   Research and development expenses increased 32% from $10.5 million in fiscal
1998 to $13.8 million in 1999, reflecting increased headcount and increased
product manufacturing development costs as newer generation products moved from
development to manufacturing.

 Sales and Marketing Expenses

   Sales and marketing expenses increased 46% from $6.8 million in fiscal 1998
to $9.9 million in 1999, reflecting higher headcount and the expansion of our
sales and marketing activities. In addition, sales and marketing expenses for
fiscal 1998 and 1999 included provisions totaling $0.6 million and $0.7
million, respectively, for potential bad debt expense.

 General and Administrative Expenses

   General and administrative expenses increased 94% from $4.0 million in
fiscal 1998 to $7.7 million in 1999, reflecting higher headcount, additional
costs of implementing systems and procedures for an independent company and
increased costs of our new facilities.

 Acquired in-process research and development and amortization of intangibles

   Acquired in-process research and development and amortization of intangibles
expense decreased 85% from $16.3 million in fiscal 1998 to $2.5 million in
1999, primarily reflecting the one-time write-off in fiscal 1998 of in-process
technology. The products under development, our newer generation products, was
80% complete at the time we purchased the Airspan unit from DSC, with an
estimated $4.1 million required to complete the project, including costs for
final development, system verification and test, documentation and release to
manufacturing processes. The new product uses a fundamentally different product
architecture and software and required an entirely new design and engineering
effort. The project was materially completed by March 31, 1998, with the first
shipment in June 1998. We expect substantially all of our hardware product
revenue will be derived from this product in 2000. See also Note 2 to the
financial statements.

 Interest and Other Income, Net

   Interest and other income increased 42% from $1.1 million in fiscal 1998 to
$1.6 million in 1999 and consisted of interest earned on cash deposits with
financial institutions. The increase from fiscal 1998 to 1999 was caused by
higher cash balances from the additional equity capital we raised. Amounts from
interest income were partially offset by fiscal 1998 and 1999 interest expense
of $1.0 million and $1.4 million, respectively, on predominately outstanding
indebtedness owed to DSC related to the purchase of the Airspan unit in January
1998.

 Income taxes

   We did not record an income tax benefit for the tax losses generated in the
U.K. The fiscal 1998 and 1999 tax provision of $0.2 million and $0.1 million,
respectively, relates to U.S. federal income taxes currently payable primarily
attributable to intercompany interest income.

 Net Loss

   Net loss decreased 17% from $35.6 million in fiscal 1998 to $29.5 million in
1999, primarily due to a decrease in acquired in-process research and
development and amortization of intangibles of $13.8 million and a $2.4 million
increase in gross margin. This decrease was offset in part by increases in
research and development, sales and marketing and general and administrative
expenses.

Comparison of Year Ended December 31, 1997 and Fiscal Period Ended December 31,
1998

 Revenue

   Revenue increased 138% from $4.8 million in 1997 to $11.5 million in fiscal
1998. Substantially all of our revenue was attributable to the older generation
products. The $6.7 million increase during fiscal 1998 was primarily a result
of system sales to new customers located in Asia Pacific and Europe. Sales to
customers in Asia Pacific increased from 0 in the year ended December 31, 1997
to 11.5% of our revenue in the fiscal period ended December 31, 1998. Sales to
customers in Europe increased from 35% in the year ended December 31, 1997 to
47.9% in the fiscal period ended December 31, 1998.

 Cost of Revenue

   Cost of revenue increased 141% from $3.9 million in 1997 to $9.5 million in
fiscal 1998. The $5.6 million increase during fiscal 1998 was largely
attributable to higher revenues as well as a $2.1 million excess inventory
provision related to older generation products. Gross profit as a percentage of
revenue decreased from 18.1% in 1997 to 17.0% in fiscal 1998 due primarily to
the inventory reserve. Gross profit in fiscal 1998 excluding the $2.1 million
inventory provision for older generation products would have been 36.7%.

 Research and Development Expenses

   Research and development expenses increased 8% from $9.7 million in 1997 to
$10.5 million in fiscal 1998. This increase was predominately due to an
increase in head count and new product development programs.

                                       26
<PAGE>

 Sales and Marketing Expenses

   Sales and marketing expenses increased 77% from $3.8 million in 1997 to $6.8
million in fiscal 1998. The increase was largely attributable to recruiting,
hiring and relocating a direct sales, marketing and technical assistance staff
during fiscal 1998. During 1997, sales of our products were made through DSC's
sales organization, which sold a variety of DSC's products, including ours. The
costs of the sales organization were not allocated by DSC and are not reflected
in our 1997 expenses.

 General and Administrative Expenses

   General and administrative expenses were unchanged at $4.0 million in 1997
and in fiscal 1998. This reflects an increase in costs related to
administrative personnel and being an independent company being offset by lower
facilities related expenses.

 Acquired in-process research and development and amortization of intangibles

   Acquired in-process research and development and amortization of intangibles
expense increased from $0.0 in 1997 to $16.3 million in fiscal 1998 primarily
reflecting the one time write-off in fiscal 1998 of in-process technology.

 Interest and Other Income, Net

   We did not have any interest income or expense in 1997 while we were a unit
of DSC. Interest and other income increased to $1.1 million for fiscal 1998 and
consisted of interest earned on cash deposits with financial institutions. This
amount was partially offset by interest expense of $1.0 million on outstanding
indebtedness of $16.0 million owed to DSC related to the purchase of the
company's assets in January 1998.

 Income Taxes

   We did not have any direct income taxes in 1997 while we were a unit of DSC.
The fiscal 1998 tax provision of $0.2 million relates to U.S. federal income
taxes primarily attributable to intercompany interest income.

 Net Loss

   We did not record net loss while we were a unit of DSC. Net loss in fiscal
1998 was $35.6 million for the reasons listed above.

Month Ended January 25, 1998

   Revenue during this period was in-line with prior period revenue. Other
expenses, including research and development, sales and marketing and general
and administrative were also in-line with prior period expenses.

   Our revenue and results of operations have fluctuated significantly from
quarter to quarter in the past, and we expect these fluctuations to continue in
the future. We have also incurred net losses in each quarter since inception,
and we expect to continue to incur losses for the foreseeable future. The
following discussion highlights significant events that have impacted our
revenues and financial results for the eight quarters ended April 2, 2000.

   During fiscal 1998, our revenue was predominantly from sales of our older
generation products. Revenue substantially decreased in the first quarter of
1999 from the fourth quarter of fiscal 1998 due to a combination of (1)
customers spending budgeted funds prior to year-end and (2) a transition during
the first quarter of 1999 from older generation products to newer generation
products, including a lower-priced subscriber terminal. Following the
commercial introduction of our new products, revenues increased in each
subsequent quarter of 1999.

                                       28
<PAGE>


   Cost of revenue, in absolute dollars, fluctuated throughout 1998, 1999 and
2000, due to a combination of manufacturing start up costs and low volume
production. Gross profits fluctuated during each year in part due to changes in
product mix and were also adversely affected by volume price discounts. We made
provisions of $2.3 million and $0.2 million for excess inventory in the fourth
quarter of fiscal 1998 and the third quarter of 1999, respectively.

Liquidity and Capital Resources

   Since inception, we have financed our operations primarily through private
sales of convertible preferred stock, which totaled $115.9 million (net of
transaction expenses) through April 2, 2000. We have also financed our
operations through equipment leases and loans aggregating an additional $5.0
million.

   At April 2, 2000, our cash and cash equivalents totaled $59.2 million,
including $3.3 million of restricted cash that is held as collateral for
performance guarantees on customer and supplier contracts and with landlords.
We do not have a line of credit or similar borrowing facility, nor do we have
any material capital commitments.

   Our long term debt consists primarily of the amount owed to DSC as part of
the purchase price paid for the company in January 1998. The debt, under a
promissory note of $17.5 million, consists of the original principal amount of
$15.0 million, plus accrued but unpaid interest. Interest accrues on the debt
at an annual rate of 7% and is compounded on a quarterly basis until February
2001, at which time principal and interest are to be repaid in equal
installments over the subsequent 36 months. The promissory note to DSC is
secured by a lien over equipment, debts, stock and all other assets of our
wholly-owned subsidiary based in the U.K. We have other term loans or
subordinated debt aggregating $4.7 million at rates ranging from 6% to 9%
annually, payable in installments over periods ranging from 21 to 54 months.
There are no financial or operating covenants attached to our DSC Note or other
term loans or subordinated debt. The amount payable under the promissory note
is still under negotiation whereby we are seeking to reduce the principal to be
paid as a result of certain claims against DSC in connection with the
acquisition.

   We used cash in operating activities of $16.2 million in fiscal 1998, $29.8
million in 1999 and $6.8 million in the quarter ended April 2, 2000. The cash
used in fiscal 1998 was primarily attributable to an operating loss of $35.6
million and an increase in accounts receivables and other current assets of
$5.8 million. This use of cash was partly offset by an in-process research and
development charge of $14.0 million, in addition to reductions in inventory,
accounts payable, other accrued expenses and depreciation and amortization of
$10.4 million. The cash we used in 1999 was mainly attributable to an operating
loss of $29.5 million, an increase in accounts receivables, inventory and other
current assets of $6.4 million and a reduction of accounts payable of
$0.3 million. These amounts were partly offset by accruals, accretion of
interest on notes payable, and depreciation and amortization of $6.3 million.
The cash used during the first quarter of 2000 was primarily attributable to an
operating loss of $7.1 million and an increase in accounts receivable,
inventory and other current assets of $1.0 million and a reduction in accounts
payable of $0.5 million. These amounts were partly offset by accruals,
accretion of interest on notes payable and depreciation and amortization of
$1.7 million.

   We used $3.3 million in cash in fiscal 1998, $4.3 million in 1999 and $0.9
million in the quarter ended April 2, 2000, for investing activities. In each
period these amounts related primarily to capital equipment purchases.

   Our financing activities from the sale of convertible preferred stock
provided us with cash of $58.2 million in fiscal 1998, $53.7 million in 1999
and $4.0 million in the quarter ended April 2, 2000. In addition, we obtained
term loan and subordinated debt aggregating $5.0 million in 1999, which was
offset in part by payments on long-term debt, including capital lease
obligations and depositing cash into a restricted account as collateral.

   We believe that the net proceeds from this offering, together with our
current cash, cash equivalents and borrowing capacity, will be sufficient to
meet our anticipated cash needs for working capital and capital expenditures
for at least the next 18 months.

Year 2000 Issues

   As a result of the change over from 1999 to 2000, none of our systems or
products were affected nor are we aware of any issues that have affected our
third party suppliers or customers.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued FASB Statement
No. 133, "Accounting for Derivative and Hedging Activities." Statement 133
establishes standards for accounting for derivative financial instruments and
hedging activities and is effective for fiscal year ending December 31, 2001.
We currently hold no derivative instruments nor do we engage in hedging
activities. Accordingly, we anticipate that the adoption of Statement 133 will
not have a material impact on our financial positions, results of operations or
cash flows.

   In March 1998, the American Institute of Certified Public Accountants, or
AICPA, issued Statement of Position, or SOP, 98-1, "Accounting for the Cost of
Computer Software Developed or Obtained for Internal Use." SOP 98-1 will be
effective for fiscal year ending September 30, 2000. SOP 98-1 provides guidance
on accounting for computer software developed or obtained for internal use
including the requirement to capitalize specified costs and amortization of
such costs. We have begun capitalizing costs in calendar year 2000.

   In April 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of Start-
Up Activities." SOP 98-5 is effective for our year ending December 31, 2000.
This SOP provides guidance on the financial reporting of start-up costs and
organization costs. It requires the costs of start-up activities and
organization costs to be expensed as incurred. We do not expect that the
adoption of SOP 98-5 will have any material impact on our financial positions,
results of operations or cash flows.

   During December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements". SAB
101 provides guidance on the recognition, presentation and disclosure of
revenue in the financial statements. Implementation of guidance prescribed in
the bulletin which applies to all registrants will not result in a change to
our revenue recognition policy.

Disclosures About Market Risk

   The following discusses our exposure to market risk related to changes in
interest rates, equity prices and foreign currency exchange rates. This
discussion contains forward-looking statements that are exposed to risks and
uncertainties. Actual results could vary materially as a result of a number of
factors, including those discussed in "Risk Factors" and elsewhere in this
prospectus.

   As of April 2, 2000, we had cash and cash equivalents of $59.2 million
(including restricted cash). Substantially all of these amounts consisted of
highly liquid investments with remaining maturities at the date of purchase of
less than 90 days. These investments are exposed to interest rate risk and will
decrease in value if market interest rates increase. A hypothetical increase or
decrease in market interest rates by 10 percent from the April 2, 2000 rates
would cause the fair market value of these short-term investments to change by
an insignificant amount. Due to the short duration of these investments, an
immediate increase in interest rates would not have a material effect on our
financial condition or results of operations. Declines in interest rates over
time will, however, reduce our interest income.

   We do not own any equity investments, other than in our subsidiaries. As a
result, we do not currently have any direct equity price risk.

   In 1999, 87% of our sales were denominated in U.S. dollars. Since a majority
of our manufacturing occurs in Sweden, a majority of our cost of goods are
denominated in Swedish krona. A large proportion of our expenses are
denominated in British pounds. We expect these proportions to fluctuate over
time. Recently, we initiated hedging activities and we will continue to monitor
our foreign currency exposures and may modify hedging strategies as we deem
prudent.

Business Overview

   We are a global supplier of fixed wireless systems that enable
communications service providers to cost effectively deliver integrated high
speed data and voice services. Our systems are based on proven, robust Code
Division Multiple Access, or CDMA, a digital wireless standard that provides
wide area coverage, security and resistance to fading. Our systems can be
deployed rapidly and cost effectively, providing an attractive alternative to
copper wire and fiber communications networks. Our products include software
tools that optimize geographic coverage of our systems and provide ongoing
network management. To facilitate the deployment and operation of our systems,
we also offer network installation, training and support services. During 1996,
we began shipping our products which were among the first fixed point-to-
multipoint systems to be commercially deployed. Our systems have been installed
by over 40 communications service providers in approximately 30 countries and
are being tested by numerous other service providers.

Industry Overview

 The Global Need for Integrated Data and Voice Communications Services

   The explosive growth in Internet use is driving the global demand for
reliable high speed access and increased bandwidth. End-users worldwide are
demanding integrated communication access solutions that include reliable high
speed data and Internet access and high quality voice telephony services. Even
in countries where communications systems are unreliable or not yet widely
deployed, businesses and consumers increasingly require Internet access and fax
and modem capabilities, in addition to basic telephone service.

 Global Deregulation and Increased Competition

   Worldwide deregulation of the telecommunications industry has created the
opportunity for new competitors to provide local access connections that
historically were offered by a single incumbent provider. Most countries in
Europe, Latin America, and Asia have joined the U.S. and the U.K. in promoting
competition for communications services. Incumbent and alternative
communications service providers are seeking to differentiate their service
offerings on the basis of their range of services, quality and reliability,
customer service, provisioning and pricing.

 Need for Cost Effective and Rapid Network Deployments

   Alternative communications service providers have expanded their focus
beyond large business customers to small and medium-sized businesses and high-
end residential, small-office/home-office customers as well as providing
services outside of the major urban areas. These markets require more cost-
effective network deployment solutions to compensate for lower average customer
spending on communications services and larger coverage area requirements.

   Many countries have networks that are unable to provide reliable data, voice
and fax services while many other countries lack the network infrastructure to
make basic telephony services broadly available. Communications service
providers in these markets, both incumbent and new entrants, need cost
effective, rapidly deployable alternatives to traditional copper based
networks. Time-to-market and the ability to offer integrated data and voice
services with attractive pricing are key success factors.

 Access Network Bottleneck

   While the communications transport network and Internet backbone are capable
of delivering data at extremely high speeds, data can only be delivered to the
end user as fast as the end-user's connection will permit. Traditional access
methods are inadequate to address the rapidly expanding bandwidth requirements.
To address this access network bottleneck, a number of alternative solutions
have emerged.

                                       31
<PAGE>

  .  Digital Subscriber Line.  Digital subscriber line, or DSL, technology
     improves the data transmission rate of existing copper networks. DSL
     transmission rates and service availability, however, are limited by
     both the quality of the available copper and the distance from the
     subscriber to the service provider's network equipment. These
     limitations restrict the use of DSL in many countries outside the U.S.,
     Canada and portions of western Europe.

  .  Cable Modems. Two-way cable modems using coaxial cable enable data
     services to be delivered over a network originally designed to provide
     television service to residential subscribers. Coaxial cable has greater
     transmission capacity than copper wires, but is often costly to upgrade
     for two-way data services. Additionally, because office buildings are
     generally not wired for cable service, it is not a viable alternative
     for many business users worldwide.

  .  Fiber Optics. Fiber optics provide the highest data transmission rate of
     any access solution, but are the most costly to deploy. As a result,
     fiber is typically used only to solve the bandwidth needs of the largest
     businesses who can justify the higher costs.

  .  Satellite. Broadband satellite solutions enable two-way access services.
     These solutions use broadcast satellite technology for high speed
     transmissions from the network service provider to the subscriber, but
     use slower wire-based connections to transmit data from the subscriber
     to the network service provider. The data rate available to each
     subscriber in a service area decreases as usage increases. As a result,
     because they are not cost effective, satellite solutions are not widely
     deployed worldwide.

 Need for Fixed Wireless Access Solutions

   The technology and cost limitations of other existing technologies have led
many communications companies to deploy fixed wireless networks because
wireless technology can deliver high performance integrated services more cost
effectively, quickly and flexibly than other solutions. The market for our
systems is a subset of the fixed wireless systems market. Currently there is no
reliable data about the size of growth rate of our target markets. Growth rates
experienced by the industry as a whole may not reflect growth rates that we or
our target markets will experience

   Wireless communications equipment operates within assigned, often licensed
frequency bands that vary as to the bandwidth of data that can be carried, the
effective range of a single cell hub and the cost of deployment. Currently
available wireless technologies include millimeter wave, wireless local area
network, fixed wireless, cordless, cellular and advanced mobile systems
technologies.

   Each of these technologies is best suited to specific applications. Systems
based on millimeter wave technologies which utilize frequencies above 10
gigahertz, or GHz, for example, provide high bandwidth services, but are costly
to deploy, have significant range limitations, require line-of-sight to provide
services and are adversely affected by weather conditions. These systems are
generally targeted at large business customers in major cities.

   Lower frequency cordless and cellular technologies have been widely deployed
to deliver wireless voice service. Cellular has a wider geographic range than
our system, while cordless and wireless local area networks have a more limited
geographic range than our system. The low bandwidth of cordless and cellular
technologies, however, make them unsuitable for delivering advanced high speed
Internet access. Wireless local area networks have greater bandwidth than our
system, but are, like cordless technologies, generally more expensive to deploy
because of their limited geographic range.

   Our systems are designed to provide communications services in the 1.5 to
4.0 GHz frequency bands, which are increasingly being licensed worldwide,
particularly in the 3.5 GHz range. These bands are

                                       32
<PAGE>


less sensitive to line-of-sight obstructions and weather conditions than the
millimeter wave technologies described above although they offer lower capacity
for data transmission.

   The combination of technology costs and performance makes this spectrum
ideal for broader market applications. Communications service providers
addressing these markets require high performance, cost effective systems
enabling integrated high speed data and voice services.

The Airspan Solution

   We are a global supplier of fixed wireless systems that enable
communications service providers to cost effectively deliver integrated high
speed reliable data and voice services. We have developed a fixed wireless
solution, which provides the following benefits:

   Integrated Data and Voice Services Platform. Our solutions enable delivery
of integrated high speed data and voice services, unlike many other access
technologies that are optimized for either data or voice traffic, but not both.
Our systems solve this problem by flexibly allocating the available bandwidth
to the services required, thereby permitting data and voice to be transmitted
efficiently. Our technology platform is designed as a modular solution to
enable our systems to evolve as our technologies and customers' needs evolve.

   Quality of Service and Reliability. Our systems are based on robust, proven
CDMA technology, which allows communications service providers to offer high
quality data and voice services with the same level of reliability that
traditional telephone networks provide. This technology provides wide area
coverage, security and resistance to fading. In addition, our systems allow
alternative service providers to bypass the incumbent's network enabling the
service provider to monitor on a real time basis the end user's network access
connection. Our products are successfully deployed and operated in a wide range
of demanding environments throughout the world.

   Rapid, Cost Effective Deployment. Our fixed wireless solutions are generally
less expensive to deploy than fiber or copper networks or other high speed
fixed wireless networks. Our systems' wide area coverage requires fewer base
stations, allowing faster deployment with lower initial capital outlays. A
single base station in urban settings covers up to 70 square miles and in rural
settings covers as much as a 700 square miles. Communications service providers
can quickly begin generating new subscriber revenues due to the reduced up-
front planning and infrastructure costs and the relative ease of installation
of our base stations. Our systems allow our customers to rapidly add new
subscribers that can be brought online in hours once the basic infrastructure
is in place. For communications service providers, the "pay as you go" approach
reduces up-front capital costs and can increase return on investment.

   Flexibility and Expandability. Our systems are highly configurable to
customer requirements for specific frequencies allocations. The modular design
of our systems allows for expansion as customer capacity requirements increase.
Our point-to-multipoint architecture also facilitates expansion by permitting
multiple subscribers to be connected to a single base station and multiple base
stations to be supported by a single access concentrator. In addition, multiple
service types, including data and voice, can be delivered over a single radio
channel enabling communications service providers to differentiate and
customize their service offerings.

   Comprehensive Implementation and Support Solutions. We offer our customers a
range of software tools that provide system-wide analysis for optimizing
geographic coverage and identifying and solving potential sources of
interference. Our software tools also initiate service for new customers and
provide alarm, maintenance and testing functions. In addition, to facilitate
deployment and operation of our systems, we offer network installation,
training and support services. The communications service provider is generally
responsible for site preparation as well as having the responsibility and
installation for subscriber terminal installation. We have also developed a
network of subcontractors that allows us to support customers wherever our
products are deployed.

Our Strategy

   Our goal is to be the leading provider of integrated fixed wireless
communications access systems to communications service providers. Key elements
of our strategy include the following:

   Capitalize on existing deployments of our systems to attract new
customers. Our numerous installations with communications service providers
worldwide serve both as proof of concept and as a basis for reference selling
to other communications service providers. We intend to build upon this early
acceptance of our products to become the primary provider of fixed wireless
systems to these service providers. We are particularly focused on expanding
our existing customer relationships to supply systems to their subsidiaries and
affiliates worldwide.

   Extend our strong technology position. We believe that we have established a
strong technology position in the market for fixed wireless solutions, and we
intend to extend this position by continuing to invest substantially in
research and development. Our expertise in wireless telecommunications and
radio frequency engineering is based on eight years of development experience
and four years of deployment experience. Our research and development efforts
are particularly focused on increasing data transmission capability and
coverage area while reducing the cost of our systems. To support our strong
technological position, we are actively involved in the development of
standards through our membership in or participation with leading standards
organizations such as the European Telecommunications Standards Institute. We
also expect to evaluate the acquisition of additional businesses, products and
technologies in order to accelerate the development of and time-to-market with
new technologically advanced products.

   Target key growth market opportunities globally. Our fixed wireless
solutions find their strongest competitive advantage in areas where there is a
growing demand for integrated high speed data and voice services and where cost
considerations make traditional solutions impracticable. As a result, in a
developed market like the United States, we focus on small and medium sized
businesses, small office/home office users and high-end consumers as well as
end users in suburban and rural areas. In the developing world, our
opportunities are much broader due to the general inadequacy of the existing
communications infrastructure. In these markets, wireless solutions can be the
basis for a new national infrastructure.

   Develop and expand our strategic relationships. We intend to develop and
expand our strategic relationships with large communications equipment
manufacturers to help us market our products to communications service
providers deploying large-scale networks. These relationships facilitate
broader deployments of our systems worldwide, through stronger sales presence
and additional integration services and support capabilities. We also intend to
form strategic relationships with communications companies situated within
certain countries where there are competitive advantages to having a local
presence. For example, in Brazil, where high import tariffs make it very
difficult for us to compete and where local relationships are important, we
have a manufacturing and marketing alliance with Tropico S.A.

   Expand global sales, marketing and customer support presence. We intend to
significantly expand our sales, marketing and customer support presence to
drive additional deployments and increase awareness of Airspan among
communications service providers. We plan to aggressively hire sales and
marketing personnel in our existing offices as well as to open new sales and
customer support offices in key strategic markets globally.

 AS4000 Fixed Wireless Access Systems

   Our AS4000 fixed wireless access systems, introduced in 1996, provide a
robust high speed CDMA technology to deliver high speed data, voice and ISDN to
a communications service provider's local access networks.

               [CLOSE UP PICTURE OF SUBSCRIBER TERMINAL VARIANTS]
          [PICTURE OF SUBSCRIBER TERMINAL ANTENNA IN MOUNTED SETTING]

  .  the AS4000 System allows the signal to travel to and from the
     subscriber's equipment (router, computer, fax or telephone) through the
     building's existing internal wiring to a subscriber interface unit

                                       35
<PAGE>

  .  the subscriber interface unit is connected by a coaxial cable to an
     external antenna which together form the subscriber terminal

  .  the antenna relays the information to the base station

  .  the signals from the various subscriber terminals (up to 2000 subscriber
     lines per base station) are routed through the base station to the
     access concentrator, normally located at the communications service
     provider's central switching center

  .  the signals are routed through the network to the final destination

   Our newer generation AS4000 System, introduced in 1998, typically allocates
a line to a subscriber terminal only when needed; for example, when a customer
picks up a telephone handset. This technology allocates spectrum efficiently
and increases total system capacity. The access concentrator assigns capacity
and provides a node for network management. Priority channels can be configured
to provide access to key users such as emergency services.

 AS8100 Network Management System

   The newer generation AS8100 Network Management System, introduced in 1998,
is a configuration, alarm, test and performance manager for the AS4000 range of
products. The management system helps ensure that the services provided over
the AS4000 network are uninterrupted and of high quality. The AS8100 is
flexible and scalable to suit a range of different networks and is available in
different versions for the network center, desktop and the field.

   The AS8100 Network Management System operates on a Microsoft Windows NT
platform and the user interface is entirely graphical and windows-based, uses
drag-down menus, icon-based representations, maps and equipment views. The
system permits communications service providers to remotely manage a
geographically dispersed set of network elements.

 AS9000 Airplan Planning and Configuration Tools

   The AS9000 Planning and Configuration Tool, introduced in 1998, is a
sophisticated planning solution that enables operators to plan and deploy our
systems. This product is based on third party software customized for use with
our systems. The main task of the planning tool is to find the optimal location
and configuration for the access concentrator and base stations of the AS4000.
The system provides a powerful prediction engine that can generate coverage
predictions for multiple scenarios until the best case scenario is found.

   Once the location of the access concentrator and base stations have been
determined, the AS9000 can be used to compare radio signal propagation and
extent of coverage. The four key aspects of the predictive tool are the terrain
(altitude) databases, clutter (natural terrain features and man-made
obstructions) information, antenna information and system configuration, which
are used to predict transmission coverage.

Technology

   As of April 2, 2000 we had 75 people engaged in research and development.
Our technology has been under continuous development since the inception of the
system design in 1993, and from the outset our goal has been to develop high
performance systems that are resilient in a wide range of deployment
conditions.

 Frequency Choice

   We recognized early that no single fixed wireless spectrum would apply
around the world. Consequently, our designs have accommodated the ability to
easily change radio frequency subsystems to match the customer's specific
spectrum allocation. We believe we have the widest choice of radio subsystems
in the industry within the 1.5 to 4.0 GHz bands.

                                       36
<PAGE>

 CDMA Technology

   CDMA is a well-established technology that allows multiple users to share
simultaneously a single radio channel while providing a high degree of security
between channels and other users. Other technologies, such as Frequency
Division Multiple Access, or FDMA, and Time Division Multiple Access, or TDMA,
and variants of these technologies, are also used to expand the number of users
within a given radio band.

   Each of these technologies, CDMA, FDMA and TDMA, function differently. CDMA
uses virtually random encoding of data, rather than dividing the frequencies
into narrow bands like FDMA or based on time intervals of the transmission like
TDMA. We selected CDMA, technology for our products because we believe CDMA can
generally allow a greater number of users per radio channel than either FDMA or
TDMA, and with greater security.

   CDMA technology is, however, more difficult to develop than FDMA or TDMA,
because of its challenging network synchronization and power control
requirements. Further, the complexity of CDMA algorithms can require multiple
computer chips and complex, customized software programs.

 Intellectual Property

   We have successfully developed a reliable and robust CDMA-based system
employing our own enabling technology which has resulted in, as of March 31,
2000, 18 separate patents granted in the U.S. and 20 pending applications in
the U.S. In order to improve system performance and reduce costs, we have
developed a custom integrated circuit, Trinity I, which is the key element of
the AS4000 System. We are currently developing next generation components that
are expected to produce further cost reductions, increased bandwidth and
enhanced functionality. We expect to deliver such components in 2000.

 Extensive testing and integration facilities

   We have taken extensive steps to ensure that our products are thoroughly
stress-tested prior to release. We have secured radio licenses for and
implemented a live multi-cell test network which provides service to a number
of volunteer customers situated in and around the town of Stratford-upon-Avon,
U.K. In addition to providing valuable long-term system reliability,
availability and other performance data, this unique facility permits us to
empirically investigate radio propagation and interference behavior for
existing and emerging products.

 Research and development expenditures

   During the fiscal year ended December 31, 1999 and the fiscal period ended
December 31, 1998, we spent $16.3 million and $26.8 million, respectively on
research and development of our products. Of such amounts, $2.5 million and
$16.3 million were, in the fiscal year 1999 and fiscal period 1998,
respectively, attributed to acquired in-process research and development and
amortization of intangibles in connection with the acquisition of the business
from DSC.

   Our contracts with our customers typically provide for delivery, training,
spare parts and maintenance and upgrade. In addition, we generally also agree
to warranty the equipment and software for a limited period of time.

   Our contracts are generally non-exclusive and contain provisions allowing
our customers to terminate the agreement without significant penalties, and
some contracts are conditional upon our customer's ability to receive foreign
regulatory approvals. Our contracts also may specify the achievement of
shipment, delivery and installation commitments. We are generally able to meet
these commitments or negotiate extensions with our customers.


Sales, Marketing and Customer Service

   We sell our systems and solutions through our direct sales force,
independent agents, resellers and OEM partners. Our direct sales force targets
communications service providers in both developed and developing markets.
Currently we have a direct sales presence in the U.S., U.K., Sweden, Denmark,
Poland, Czech Republic, Brazil, the Philippines, South Korea, Sri Lanka and
Canada. In markets where we do not have a direct sales presence, we also sell
through independent agents and resellers who target communications service
providers. In certain countries we also sell to OEMs who may sell our products
under their names.

   Our marketing efforts are focused on communications service providers that
provide integrated communications services to their customers. Through our
marketing activities, we provide technical and strategic sales support
including in-depth product presentations, technical manuals, sales tools,
pricing, marketing communications, marketing research, trademark administration
and other support functions.

   A high level of ongoing service and support is critical to our objective of
developing long-term customer relationships. In order to facilitate the
deployment of our systems, we offer our customers a wide range of
implementation and support services including spectrum optimization and network
management, installation, training and support services.

   Most major installations are performed by our subcontractors who have the
expertise and ability to professionally install our products. This enables us
to efficiently manage fluctuations in volume of installation work.

   As of April 2, 2000, we had 57 employees dedicated to sales, marketing and
customer service.

Manufacturing

   We outsource our manufacturing to global contract manufacturers in order to
realize the advantages in cost, quality and volume and geographic flexibility.
We currently outsource most of our manufacturing to Flextronics International,
located in Karlskrona, Sweden. Flextronics and one other contract manufacturer
provided 66% and 93% of our manufactured products in 1999 and 1998,
respectively. We have an agreement with Flextronics dated August 27, 1999 for a
period of two years, which may be extended an additional year by either party.
Either party may terminate this agreement. The agreement also requires us to
provide a bank guarantee in respect of subcontractor debt and inventory
exposure in favor of Flextronics, which was $1.85 million at May 23, 2000. Our
manufacturing support activities consist primarily of prototype development,
materials planning and procurement, final product assembly testing and quality
control.

   Our contract with Flextronics is non-exclusive and may be terminated with
four months' notice by either party without significant penalty. Other than
agreeing to purchase the materials we request in the forecasts, we do not have
any agreements with them to purchase any minimum volume.

   Our operation and manufacturing strategies enable us to configure our
products to meet a wide variety of customer requirements and facilitate
technology transfer between our research and development group and our contract
manufacturers. We are ISO 9001 certified.

Competition

   Competition in our markets is intense and involves rapidly-changing
technologies and customer requirements. We compete with established vendors of
communications systems, including traditional wired communications systems.

   We believe several factors make Airspan a strong competitor including:

  .  range of product offerings (data, voice and ISDN)

  .  quality and performance of our products

  .  high quality customer service

  .  ability to implement and integrate solutions

   The primary competitive challenges our business faces include:

  .  competing with established and installed traditional wired networks

  .  convincing alternative service providers that our service is superior to
     other potential wireless solutions

   We face, or believe that we will face, competition from various other
providers of wireless communications products and services, including ECI,
Lucent and AT&T. While we believe our industry to be competitive, we do not
believe there to be a single dominant competitor.

                                       39
<PAGE>


   Competitors vary in size and scope, in terms of products and services
offered. In the particular frequencies where we operate, we compete directly
with ECI and Lucent, as well as smaller start-up companies. We compete
indirectly with a number of large telecommunication equipment suppliers such as
Alcatel, Ericsson, Hughes, and Nortel. In addition, our technology competes
with other high speed solutions, such as digital subscriber lines, optical
fiber cable, cable modems and high speed leased lines and satellite
technologies. Finally, our business may compete in the future with products and
services based on other wireless technologies including TDMA, FDMA and other
technologies that have yet to be developed.

Intellectual Property Rights

   We rely on a combination of copyright, patent, trademark, trade secret and
other intellectual property laws together with confidentiality and/or license
agreements with our employees, customers and others to protect our proprietary
rights. Our patent portfolio consists of, as of April 2, 2000, 18 patents that
have been granted in the U.S., together with their foreign counterparts. We
also have 20 U.S. patent applications that are currently pending, together with
their foreign counterparts. Our other intellectual property rights relate to
the trademark and trade name Airspan(R), our website, our software and hardware
design and technology.

Employees

   As of April 2, 2000, we had a total of 217 full-time employees, including
contract personnel. Our employees are not presently represented by a labor
union. We have not experienced any work stoppages and consider our relations
with our employees to be good.

Properties

   We are headquartered in Uxbridge, U.K. where we lease three facilities with
approximately 25,000, 17,000 and 12,000 square feet, respectively. These leases
expire in 2006, 2010 and 2003, respectively.

Legal Proceedings

   We are not currently subject to any material legal proceedings. We may from
time to time become a party to various legal proceedings arising in the
ordinary course of our business.

Stock Plans

 1998 Stock Option and Restricted Stock Plan

   Our 1998 Stock Option and Restricted Stock Plan was adopted by our board of
directors and approved by our shareholders on February 1, 1998. As of April 2,
2000, options to purchase a total of 733,725 shares of common stock had been
exercised, options to purchase a total of 1,776,851 shares at a weighted
average exercise price of $1.94 per share were outstanding, and 281,090 shares
remained available for future option grants.

   The plan provides for the grant to our employees (including officers and
employee directors) of "incentive stock options" within the meaning of Section
422 of the Internal Revenue Code of 1986 and for the grant of nonstatutory
stock options to our employees, officers, directors and consultants. Non-
employee directors are not eligible for option grants under the plan. To the
extent an optionee would have the right in any calendar year to exercise for
the first time one or more incentive stock options for shares having an
aggregate fair market value (under the plan and determined for each share as of
the date the option to purchase the share was granted) in excess of $100,000,
any such excess options are treated as nonstatutory stock options.

   The plan is administered by the board of directors or a committee of the
board of directors. The administrator determines the terms of options granted
under the plan, including the number of shares subject to the option, exercise
price, term and exercisability. The exercise price of all incentive stock
options granted under the plan must be at least equal to the fair market value
of our common stock on the date of grant. The exercise price of all
nonstatutory stock options granted to persons who are not 10% shareholders
cannot be less than 100% of the fair market value of our common stock on the
date of grant. The administrator determines the term of options. The term of an
incentive stock option granted under the plan may not exceed ten years. Options
granted to each employee under the plan generally become exercisable at the
rate of 25% of the total number of shares subject to the options after the
first anniversary following the date of grant, with 2.778% vesting monthly
thereafter.

   In the event of certain changes in control, our stock options generally
require that each outstanding option be assumed or an equivalent option
substituted by the successor corporation. In the event that a successor
corporation refuses to assume each option or substitute an equivalent option,
the administrator shall provide for the optionee to have the right to exercise
the option as to 50% of the remaining unvested options, including shares as to
which the option would not otherwise be exercisable. The administrator has the
authority to amend or terminate the plan as long as such action does not
adversely affect any outstanding option and provided that shareholder approval
shall be required for an amendment to increase the number of shares subject to
the plan, or any change in the designation of the class of persons eligible to
be granted options, or a material increase in benefits accruing to participants
under the plan if a class of our shares is registered under Section 12 of the
Securities Exchange Act of 1934. If not terminated earlier, the plan will
terminate February 1, 2008.

 2000 Employee Stock Purchase Plan

   Our 2000 Employee Stock Purchase Plan was adopted by our board of directors
on May 17, 2000 and shareholders on May 24, 2000. A total of 500,000 shares of
common stock has been reserved for issuance under the purchase plan. The
purchase plan, which is intended to qualify under Section 423 of the Internal
Revenue Code, generally will be implemented in a series of offering periods of
one year duration with new offering periods (other than the first offering
period) commencing on August 1 and ending on the following July 31, with the
last day of each period being designated as a purchase date. The first offering
period will commence on the effective date of this offering and continue
through July 31, 2001. The purchase plan will be

                                       45

administered by our board of directors or a committee appointed by our board of
directors. Our employees (including officers and employee directors) or
employees of any subsidiary are eligible to participate if they are employed by
us or any subsidiary for at least 20 hours per week and more than five months
per year. The purchase plan permits eligible employees to purchase common stock
through payroll deductions, which may not exceed 10% of an employee's
compensation, at a price equal to the lower of 85% of the fair market value of
our common stock at the beginning of the offering period or the purchase date.
Employees may end their participation in the offering at any time prior to the
last business day of the offering period, and participation ends automatically
on termination of employment with us. In addition, participants may decrease
their level of payroll deductions once during an offering period.

   Our board of directors may amend or terminate the purchase plan as long as
any outstanding rights to purchase stock thereunder are not adversely affected.
If not terminated earlier, the purchase plan will terminate on July 31, 2006.

   In connection with our acquisition of the Airspan assets from DSC in January
1998, Sevin Rosen Funds, Oak Investment Partners and InterWest Partners agreed
to purchase our Series A convertible preferred stock. All of these entities may
be deemed to be promoters of Airspan. Other than purchasing Series A preferred
stock at the same price per share as other investors in our Series A
convertible preferred stock financing, Sevin Rosen Funds, Oak Investment
Partners and InterWest Partners did not receive any item of value, nor did
these entities sell any property or assets to Airspan.

   The original purchasers of our common stock include SeaPoint Ventures, of
which Mr. Huseby, a director, is the managing partner. SeaPoint Ventures paid
$0.03 per share, with an aggregate capital contribution of $16,250, for
approximately 0.004% of Airspan's capitalization (based on our capitalization
immediately following the Series A financing) and 4.0% of the issued shares
(based on our issued shares immediately following the Series A financing).

   As compensation for performing services in the original formation of
Airspan, SeaPoint Ventures was issued 333,333 shares of common stock at $0.03
per share. In addition, SeaPoint later purchased 83,333 shares of common stock
for $0.54 per share in connection with our Series B convertible preferred
stock.

   In 1998 and 1999, we paid $220,000 and $263,000, respectively, to SeaPoint
Ventures for executive management and accounting services.

   On February 16, 1998 we sold to Eric Stonestrom, our president and chief
executive officer, 333,333 shares of common stock at $0.10 per share. We have
an option to repurchase these shares at the same price if Mr. Stonestrom's
employment with us is terminated for any reason. On May 12, 1998 we sold an
additional 166,667 shares to Mr. Stonestrom at the same price, with the same
repurchase option. On April 27, 1999 we entered into two promissory notes
reflecting the remaining $130,000 Mr. Stonestrom owes for the purchase of the
common stock, which is required to be paid upon a change of control of the
company. The notes are secured by the common stock.

   We believe that the transactions described in this section were made on
terms no less favorable than could have been obtained from third parties. Prior
to the closing of this offering, we will adopt a policy that requires, unless
otherwise approved by a disinterested majority of directors as required by
Washington law, all future transactions between Airspan and its officers,
directors and affiliates to be on terms no less favorable than could be
obtained from unaffiliated third parties.

 (1)  Beneficial ownership is determined in accordance with the rules of the
      Securities and Exchange Commission. Applicable percentage ownership is
      based on 28,915,868 shares of common stock outstanding as of April 2,
      2000, including 83,333 shares issuable upon exercise of warrants,
      together with options for that shareholder that are currently exercisable
      or exercisable within 60 days of April 2, 2000. In computing the number
      and percentage of shares beneficially owned by a person, shares of common
      stock subject to options currently exercisable, or exercisable within 60
      days of April 2, 2000 are counted as outstanding, while these shares are
      not counted as outstanding for computing the percentage ownership of any
      other person. The percentage of shares outstanding after the offering is
      calculated after giving effect to the issuance of 5,000,000 shares of
      common stock offered by this prospectus, assuming no exercise of the
      underwriters' over-allotment option.

                          DESCRIPTION OF CAPITAL STOCK

   Our amended and restated articles of incorporation authorize the issuance of
50,000,000 shares of common stock, $0.0003 par value per share and 86,000,000
shares of preferred stock, $0.0001 par value per share. Excluding the shares
offered hereby, we will have 28,281,572 shares of common stock issued and
outstanding, including 26,916,667 shares of common stock issued on the
conversion of our preferred stock immediately prior to the closing of the
offering. Upon this conversion, our articles of incorporation will authorize
the issuance of 5,000,000 shares of preferred stock, of which none will be
outstanding.

   Certain provisions of our articles of incorporation and bylaws and
Washington law may discourage, delay or prevent a merger or acquisition that a
shareholder may consider favorable. These provisions include:

  .  authorizing the board of directors to issue additional common and
     preferred stock

  .  not permitting cumulative voting in the election of directors

  .  limiting the persons who may call special meetings of shareholders

  .  not permitting shareholder action by written consent

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

   We are also subject to certain provisions of Washington law that could
delay, deter or prevent us from entering into an acquisition. Chapter 19 of the
Washington Business Corporation Act prohibits a Washington corporation such as
Airspan from engaging in a business combination with an interested shareholder
unless specific conditions are met.

Common Stock

   Holders of common stock are entitled to one vote per share on all matters to
be voted upon by the shareholders generally, including the election of
directors. Holders of common stock have no cumulative voting rights and no
preemptive or conversion rights. There are no redemption or sinking fund
provisions available to the holders of common stock. Subject to preferences
that may be applicable to any then-outstanding preferred stock, holders of
common stock will be entitled to receive ratably such dividends as may be
declared by our board of directors out of funds legally available for such
dividends. In the event of a liquidation, dissolution or winding up of Airspan,
holders of common stock will be entitled to share ratably in all assets
remaining after payment of liabilities and the liquidation preference to any
then-outstanding holders of preferred stock.

Preferred Stock

   As of the closing of this offering, our articles of incorporation authorize
us to issue 5,000,000 shares of preferred stock, which may be issued from time
to time in one or more classes or series or both upon authorization by our
board of directors. Our board of directors, without further approval of the
shareholders, is authorized to fix the dividend rights and terms, conversion
rights, voting rights, redemption rights and terms, liquidation preferences and
any other rights, preferences, privileges and restrictions applicable to each
class or series of preferred stock. The issuance of preferred stock, while
providing flexibility in connection with possible acquisitions and other
corporate purposes, could adversely affect the voting power of the holders of
our common stock and, under certain circumstances, make it more difficult for a
third party to gain control of Airspan, discourage bids for our common stock at
a premium, or otherwise adversely affect the market price of our common stock.
We have no current plan to issue preferred stock.

Warrants and other Rights

   As of May 23, 2000, there were outstanding warrants to purchase 249,998
shares of preferred stock convertible into 83,333 shares of common stock with
an exercise price of $1.75 that will expire three years from the date of this
prospectus.

                                       53
<PAGE>

Registration Rights of Certain Holders

   The holders of 80,750,002 shares of preferred stock that will convert into
26,916,667 shares of common stock, or their transferees, are entitled to some
rights with respect to the registration of these shares under the Securities
Act. These rights are provided under the terms of an agreement between us and
the holders of registrable securities. Subject to some limitations in this
agreement, the holders of the registrable securities may require, on three
occasions at any time after one year from the effective date of this offering,
that we use our best efforts to register the registrable securities, for public
resale, provided that the proposed aggregate offering price exceeds
$10,000,000. If we register any of our common stock either for our own account
or for the account of other security holders, the holders of registrable
securities are entitled to include their shares of common stock in the
registration. A holder's right to include shares in an underwritten
registration is subject to the ability of the underwriters to limit the number
of shares included in the offering. All fees, costs and expenses of such
registrations must be borne by us and all selling expenses, including
underwriting discounts, selling commissions and stock transfer taxes, relating
to registrable securities must be borne by the holders of the securities being
registered.

Business Combination Statute

   The Washington Business Act, Section 23B.19 of the Revised Code of
Washington, prohibits a "target corporation," with certain exceptions, from
engaging in certain "significant business transactions," such as a merger or
sale of assets, with an "acquiring person" who acquires more than 10% of the
voting securities of the target corporation for a period of five years after
such acquisition, unless the transaction is approved by the majority of the
members of the target corporation's board of directors prior to the date of the
transaction or unless the aggregate amount of the cash and the market value of
non-cash consideration received by holders of outstanding shares of any class
or series of stock of the target corporation is equal to certain minimum
amounts. Our Articles of Incorporation provide that we will be subject to such
prohibitions and shall remain subject to such prohibitions even if the law is
repealed.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services, L.L.C.

Listing

   We have applied to list the common stock on The Nasdaq Stock Market's
National Market under the symbol "AIRN."

                        SHARES ELIGIBLE FOR FUTURE SALE

   Upon completion of this offering, we will have outstanding 33,281,572 shares
of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options or warrants after April 2, 2000.
Of these shares, the 5,000,000 shares of common stock sold in this offering
will be freely tradable 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 28,281,572 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.

   Our executive officers, directors and our other securityholders have entered
into lock-up agreements in which they have agreed that, for a period of 180
days after the date of this prospectus, they will not offer, sell, contract to
sell, pledge or otherwise dispose of any shares of our common stock, or any
securities convertible into or exchangeable or exercisable for any shares of
our common stock, or publicly disclose their intention to make any offer, sale,
contract, pledge or disposal, without the prior written consent of Credit
Suisse First Boston Corporation, other than shares of common stock acquired
pursuant to this offering or in the open market or transferred (i) as a bona
fide gift or gifts, or (ii) as a distribution to the partners, members, or
shareholders of the holder, provided the transferee(s) has agreed to be bound
in writing by the terms of this the lock-up agreement. In addition, we have
agreed in the underwriting agreement that, for a period of 180 days after the
date of this prospectus, we will not offer, sell, contract to sell, pledge or
otherwise dispose of any shares of our common stock, or any securities
convertible into or exchangeable or exercisable for any shares of our common
stock, or publicly disclose our intention to make any offer, sale, contract,
pledge or disposal, without the prior written consent of Credit Suisse First
Boston Corporation. We have similarly agreed that, with limited exceptions, we
will not file a registration statement with the SEC or publicly disclose our
intention to do so. Credit Suisse First Boston Corporation may, at any time and
without notice, waive any of the terms of these lock-up agreements.

   Under these lock-up agreements, our outstanding shares of common stock will
be available for sale in the public market as follows:

</TABLE>

   In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned restricted shares for at least one year, including
persons who may be deemed our "affiliates," would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of
(a) 1% of the number of shares of common stock then outstanding or (b) the
average weekly trading volume of the common stock as reported through the
Nasdaq National Market during the four calendar weeks preceding the filing of a
Form 144 with respect to such sale. Sales under Rule 144 are also subject to
certain manner of sale provisions and notice requirements and the availability
of current public information about us. In addition, a person who is not deemed
to have been our affiliate at any time during the 90 days preceding a sale and
who has beneficially owned for at least two years the shares proposed to be
sold would be entitled to sell such shares under Rule 144(k) without regard to
the requirements described above. Persons deemed to be "affiliates" must always
sell pursuant to Rule 144, even after the applicable holding periods have been
satisfied.

                                       55
<PAGE>

   In general, Rule 701 permits resales of shares issued pursuant to certain
compensatory benefit plans and contracts commencing 90 days after the issuer
becomes subject to the reporting requirements of the Securities Exchange Act of
1934 in reliance upon Rule 144 but without compliance with certain
restrictions, including the holding period requirements, contained in Rule 144.
We will file registration statements on Form S-8 under the Securities Act of
1933 to register common stock issuable under our stock option plans and stock
purchase plan. Such registration will permit the resale of shares in the public
market without restriction under the Securities Act.

   We intend to file, after the effective date of this offering, a registration
statement on Form S-8 to register up to approximately 2.1 million shares of
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 the stock plans may
be sold in the open market, unless the sale is limited by the provisions of
Rule 144 applicable to our affiliates or the lock-up agreements.

   No prediction can be made as to the effect, if any, that market sales of
shares or the availability of shares for sale will have on the market price
prevailing from time to time. Nevertheless, sales of substantial amounts of our
common stock in the public market after the lapse of the restrictions described
above could adversely affect the prevailing market price and our ability to
raise equity capital in the future.

</TABLE>

   The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares of common stock in the offering if any are
purchased, other than those shares covered by the over-allotment option
described below. The underwriting agreement also provides that if an
underwriter defaults, the purchase commitments of non-defaulting underwriters
may be increased or the offering of common stock may be terminated.

   We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to     additional shares at the initial public offering price
less the underwriting discounts and commissions. The option may be exercised
only to cover any over-allotments of common stock.

   The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $    per share. The
underwriters and selling group members may allow a discount of $    per share
on the sales to other broker/dealers. After the initial public offering, the
public offering price, concession and discount to broker/dealers may be changed
by the representatives.

   The following table summarizes the compensation and estimated expenses we
will pay.

   The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common stock being offered.

   We, our officers and directors and other shareholders holding an aggregate
of        shares have agreed that we and they will not offer, sell, contract to
sell, announce our intention to sell, pledge or otherwise dispose of, directly
or indirectly, or, in our case, file with the Securities and Exchange
Commission a registration statement under the Securities Act of 1933 relating
to, any shares of our common stock or securities convertible into or
exchangeable or exercisable for any of our common stock without the prior
written consent of Credit Suisse First Boston Corporation for a period of 180
days after the date of this prospectus, except in certain limited exceptions.

   The underwriters have reserved for sale, at the initial public offering
price, up to        shares of the common stock for some of our vendors,
customers, employees, directors and other people and entities with whom we
maintain business relationships who have expressed an interest in purchasing
common stock in the offering. The number of shares available for sale to the
general public in the offering will be reduced by the

                                       57
<PAGE>

number of the reserved shares purchased. Any reserved shares not purchased will
be offered by the underwriters to the general public on the same terms as the
other shares.

   We have agreed to indemnify the underwriters against liabilities under the
Securities Act of 1933, or contribute to payments which the underwriters may be
required to make.

   We intend to apply to list the common stock on The Nasdaq Stock Market's
National Market under the symbol "AIRN."

   Deutsche Bank Securities Inc., an underwriter in this offering, is an
affiliate of DB Overseas Holdings Limited, one of our shareholders. Deutsche
Bank Securities Inc. and DB Overseas Holdings Limited are both owned by
Deutsche Bank AG through its subsidiaries.

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price has been determined by negotiations
between us and the representatives. The principal factors considered in
determining the public offering price included:

  .  the information set forth in this prospectus and otherwise available to
     the representatives

  .  the history and the prospects for the industry in which we compete

  .  the ability of our management

  .  the prospects for our future earnings

  .  the present state of our development and our current financial condition

  .  the general condition of the securities markets at the time of this
     offering

  .  the recent market prices of, and the demand for, publicly-traded common
     stock of generally comparable companies

   The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Securities Exchange Act of 1934. A description of each of these
terms is below:

  .  over-allotment involves syndicate sales in excess of the offering size,
     which creates a syndicate short position

  .  stabilizing transactions permit bids to purchase the underlying security
     so long as the stabilizing bids do not exceed a specified maximum

  .  syndicate covering transactions involve purchase of the common stock in
     the open market after the distribution has been completed in order to
     cover syndicate short positions

  .  penalty bids permit the representatives to reclaim a selling concession
     from a syndicate member when the common stock originally sold by such
     syndicate member is purchased in a syndicate covering transaction to
     cover syndicate short positions

These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of these transactions. These transactions may be
effected on The Nasdaq Stock Market's National Market or otherwise and, if
commenced, may be discontinued at any time.

   A prospectus in electronic format may be made available on the web sites
maintained by one or more of the underwriters participating in this offering.
The representatives may agree to allocate a number of shares to underwriters
for sale to their online brokerage account holders. Internet distributions will
be allocated by the underwriters that will make internet distributions on the
same basis as other allocations.

                          NOTICE TO CANADIAN RESIDENTS

   The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common
stock in Canada must be made under securities laws which will vary depending on
the relevant jurisdiction, and which may require resales to be made under
available statutory exemptions or under a discretionary exemption granted by
the Canadian securities regulatory authority that has jurisdiction. Purchasers
are advised to seek legal advice prior to any resale of the common stock.

Representations of Purchasers

   Each purchaser of common stock in Canada who receives a purchase
confirmation will represent to us and the dealer from whom the purchase
confirmation is received that:

  .  the purchaser is entitled under the provincial securities laws that
     apply to the purchaser to purchase the common stock without the benefit
     of a prospectus qualified under these securities laws;

  .  the purchaser is purchasing as principal and not as agent if the
     purchaser is not allowed to purchase as agent under the provincial
     securities laws that apply to the purchaser;

  .  the purchaser has reviewed the text above under "Resale Restrictions."

Rights of Action of Ontario Purchasers

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

Enforcement of Legal Rights

   All of the issuer's directors and officers as well as the experts named in
this prospectus may be located outside Canada and, as a result, it may not be
possible for Canadian purchasers to serve process within Canada upon the issuer
or these persons. All or a substantial portion of the assets of the issuer and
these persons may be located outside Canada and, as a result, it may not be
possible to satisfy a judgment against the issuer or these persons in Canada or
to enforce a judgment obtained in Canadian courts against the issuer or these
persons outside Canada.

Notice to British Columbia Residents

   A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that the purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by the purchaser under this offering. This report must be
in the form attached to British Columbia Securities Commission Blanket Order
BOR #95/17, a copy of which may be obtained from us. Only one report must be
filed for common stock acquired on the same date and under the same prospectus
exemption.

Taxation and Eligibility for Investment

   Canadian purchasers of common stock should consult with their own legal and
tax advisors about the tax consequences of an investment in the common stock in
their particular circumstances and about the eligibility of the common stock
for investment by the purchaser under Canadian legislation.

                         REPORT OF INDEPENDENT AUDITORS

To: The Board of Directors and Shareholders
  Airspan Networks Inc.

   We have audited the accompanying statement of revenues and direct costs and
expenses of the Predecessor Business for the year ended December 31, 1997 and
the month ended January 25, 1998 and consolidated balance sheets of Airspan
Networks Inc. as of December 31, 1998 and December 31, 1999, and the related
consolidated statements of operations, stockholders' equity and cash flows for
the eleven month period ended December 31, 1998 and the year 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 United States generally accepted
auditing standards. Those standards require that we plan and perform the audit
to obtain reasonable assurances about whether the financial statements are free
from 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 the management, as well as evaluating the overall financial
presentation. We believe our audits provide a reasonable basis for our opinion.

   As discussed in Note 1, the accompanying financial statements of the
Predecessor Business have been prepared solely to present the revenue and
direct costs and expenses of the Predecessor Business for the year ended
December 31, 1997 and month ended January 25, 1998 for the purpose of complying
with the requirements of the Securities and Exchange Commission and is not
intended to be a complete presentation of the financial results of operations
of the Predecessor Business.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the revenues and direct costs and expenses of the
Predecessor Business for the year ended December 31, 1997 and the month ended
January 25, 1998 and consolidated financial position of Airspan Networks Inc.
at December 31, 1998 and December 31, 1999 and the consolidated results of its
operations and its consolidated cash flows for the eleven month period ended
December 31, 1998 and the year ended December 31, 1999 in conformity with
United States generally accepted accounting principles.

                       NOTES TO THE FINANCIAL STATEMENTS
              (in thousands, except for share and per share data)

1. THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Business

   The Company is a global supplier of fixed wireless communications access
systems that enable communications service providers to deliver integrated high
speed data and voice services. The Company's systems are based on Code Division
Multiple Access, CDMA, technology that can be deployed rapidly and cost
effectively, providing an alternative to traditional wireline communications
networks. The Company's integrated solutions include software tools that
provide coverage and spectrum optimization and ongoing network management. To
facilitate the deployment and operation of its systems, the Company also offers
network installation, integration, training and support services. The Company's
main operations are based in Uxbridge, United Kingdom.

 Basis of presentation for the Predecessor

   Airspan Networks Inc. (the "Company" or "Airspan") was formed as a U.S.
company in January 1998 and is now incorporated in the State of Washington. The
Company was formed simultaneously with the acquisition of a business unit of
DSC Communications Corporation ("DSC") that began development of fixed wireless
access systems in 1994. In accordance with the terms of the acquisition, the
assets and liabilities of the business unit were transferred from DSC to the
Company on January 26, 1998. The assets and liabilities acquired were the fixed
wireless communications access systems operations of DSC (the "Predecessor
Business"). These operations consisted of a research and development function,
product management, direct sales and marketing and direct general and
administration costs.

   The Predecessor Business was not a separate legal entity and its operations
formed part of the activities of several legal entities within DSC world wide.
Except for compilations of product line revenue, direct costs, direct expenses
and corporate allocations, no separate financial statements of the Predecessor
Business were prepared in the past. The assets and liabilities associated with
the Predecessor Business were components of larger business units. Accordingly,
other than certain inventory and equipment, the assets and liabilities of the
Predecessor Business were not identified or maintained in separate accounts. In
addition, the Predecessor Business did not maintain its own cash accounts.
Given these constraints, the balance sheets of the Predecessor Business and
related statement of operations and cash flows have not been presented.

   Certain costs and expenses incurred by DSC were allocated to individual
product lines, including the Predecessor Business, on various bases, applying
internal management allocations. These corporate allocations are not
necessarily indicative of the level of expenses which might have been incurred
had the Predecessor Business been operated as an independent business. The
accompanying statement of revenues and direct costs and expenses of the
Predecessor Business do not include DSC corporate allocations of certain
overhead, general and administrative expenses, interest expense and income
taxes as it is impracticable to allocate such expenses arbitrarily on a
retroactive basis.

   The accompanying statement of revenues and direct costs and expenses of the
Predecessor Business was prepared solely to comply with the requirements of the
Securities and Exchange Commission. These financial statements are not intended
to be a complete presentation of the results of operations of the Predecessor
Business.

 Effect of the three for one reverse split

   On May 25, 2000 the common stock of the Company underwent a three for one
reverse split. For comparative purposes we have in these financial statements
shown outstanding common stock numbers as if the split was retroactive. The
reverse split reduced our outstanding common stock by 66.7% and correspondingly
increased our loss per share by 200% across all periods since the acquisition
of the Predecessor business.

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
              (in thousands, except for share and per share data)


 Principles of consolidation

   The consolidated financial statements include the accounts of the Company
and its subsidiary which is wholly-owned. All significant inter-company
transactions and balances have been eliminated on consolidation.

 Use of estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

 Interim Financial Information

   The unaudited condensed financial statements as of and for the quarter ended
April 4, 1999 and April 2, 2000 have been prepared in accordance with generally
accepted accounting principles for interim financial information and Article 10
of Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles. The unaudited
financial statements include, in the opinion of management, all adjustments,
consisting of only normal recurring adjustments, that are considered necessary
for the fair presentation of the information in the financial statements. All
footnote disclosures included in these financial statements related to the
quarter ended April 4, 1999 and April 2, 2000 are unaudited.

 Cash equivalents

   The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.

 Fair value of financial instruments

   The financial instruments of the Company consist mainly of cash and cash
equivalents, restricted cash, accounts receivable, accounts payable and
promissory notes. In view of their nature, the fair value of the financial
instruments included in the accounts of the company does not significantly vary
from their carrying amount.

 Inventories

   Inventories are stated at the lower of cost or market value. Cost includes
all costs incurred in bringing each product to its present location and
condition, as follows:

     Raw materials, consumables and goods for resale--average cost

     Work in progress and finished goods--cost of direct materials, labor and
  allocated manufacturing overhead

 Property and equipment

   Property and equipment are stated at cost. Depreciation is provided on all
tangible fixed assets at rates calculated to write off the cost, less estimated
residual value based on prices prevailing at the date of acquisition, of each
asset evenly over its expected useful life, as follows:

     Leasehold improvements--over the minimum lease term

     Plant, machinery and equipment--over 2 to 5 years

     Furniture and fixtures--over 4 to 5 years

                                      F-8

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
              (in thousands, except for share and per share data)


 Identifiable intangible assets

   Identifiable intangible assets arose in connection with the acquisition of
the Predecessor Business. They are stated at allocated cost and include
developed technology, purchase contracts, patents and assembled workforce.
Identifiable intangible assets are amortized using the straight line method
over their estimated useful lives ranging from two to four years.

 Goodwill arising on business combinations

   The excess of the purchase price (including associated expenses) paid over
net assets of the business acquired is being amortized over its estimated
useful life of ten years on the straight-line method. The Company reviews the
recoverability of goodwill whenever events or changes in circumstances indicate
that its carrying value may not be recoverable from the anticipated future cash
flows of the related businesses on an undiscounted basis. A loss is recognized
for the difference between the carrying value and the estimated fair value of
the asset.

 Restricted cash

   Restricted cash consists of bank accounts set aside for the guarantees
described in note 8.

 Impairment of long lived assets

   In accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be Disposed", the Company reviews its long-lived assets for impairment when
events or changes in circumstances indicate that the carrying value of such
assets may not be recoverable. This review consists of a comparison of the
carrying value of the asset with the asset's expected future undiscounted cash
flows. Estimates of expected future cash flows represent management's best
estimate based on reasonable and supportable assumptions and projections. If
the expected future cash flows exceed the carrying value of the asset, no
impairment is recognized. If the carrying value of the asset exceeds the
expected future cash flows, an impairment exists and is measured by the excess
of the carrying value over the fair value of the asset. Any impairment
provisions recognized are permanent and may not be restored in the future. No
impairment expense was recognized in 1997, 1998 or 1999.

 Product development

   All product development expenditures are charged to product development
expense in the period incurred. Generally accepted accounting principles
require the capitalization of certain software development costs after
technological feasibility of the software is established. In the development of
the Company's new products and enhancements to existing products, the
technological feasibility of the software is not established until
substantially all product development is complete, including the development of
a working model. Internal software development costs that were eligible for
capitalization were insignificant and were charged to research and development
expense in the accompanying statements of operations.

 Revenue recognition

   Revenue is recognized when all significant contractual obligations have been
satisfied and the collection of resulting revenues is reasonably assured. For
most product sales, revenue recognition occurs on shipment. For contracts with
non standard terms, revenue is recognized when these terms have been satisfied.
Revenue from customer service contracts is recognized once the services have
been rendered. Any billings in excess of revenue recognized for products or
services are classified as deferred income or customer advances.

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
              (in thousands, except for share and per share data)

 Warranty

   The Company provides a limited warranty for periods usually ranging from
twelve to twenty-four months, to all purchasers of its new equipment. Warranty
expense is accrued at the date revenue is recognized on the sale of equipment.
Management believes that the amounts provided for are sufficient for all future
warranty cost on equipment sold through April 2, 2000.

 Foreign currency transactions

   Transactions in currencies other than dollars are converted at the exchange
rate on the date of the transaction. The Company's functional currency is the
U.S. dollar for its only subsidiary in the U.K.

   Monetary assets and liabilities denominated in currencies other than U.S.
dollars are translated into U.S. dollars at the rate of exchange on the balance
sheet date. All differences resulting from realized and unrealized gains and
losses are recognized in the statement of operations as other income or
expense.

 Concentration of credit risk

   Financial instruments which potentially subject Airspan to concentration of
credit risk consist primarily of cash and cash equivalents and accounts
receivable. Airspan places its cash equivalents and short-term investments only
in highly rated financial instruments. Airspan's accounts receivable are
derived from sales of wireless local loop products and approximately 73% and
96% of product sales were non U.S. sales for the 11 month period ended December
31, 1998 and the year ended December 31, 1999, respectively. Approximately 93%
and 98% of product sales were non U.S. sales for the first quarters of 1999 and
2000 respectively (see Note 9). Airspan generally requires a U.S. dollar
irrevocable letter of credit for the full amount of significant sales to be in
place at the time of shipment, except in cases where credit risk is considered
to be acceptable. The Predecessor Business derived 76% of revenue from four
customers in 1997 and 78% of revenue from one customer in January 1998. Airspan
derived 46% of revenue from three customers in the 11 months ended December
1998, 59% of revenue from three customers in 1999 and 77% of revenue from three
customers in the first quarter of 1999 and 82% of revenue from three customers
in the first quarter of 2000. The Predecessor Business received 100% in 1997
and January 1998 of goods for resale from one supplier, DSC Telcom LP. Airspan
received 93% in 1998, 66% in 1999 and 96% in the quarter ended April 4, 1999 of
goods for resale from two suppliers, DSC Communications Ireland and Flextronics
International AB in the quarter ended April 2, 2000 53% of goods for resale
were received from one supplier, Flextronics International AB. These suppliers
act as sub-contractors to manufacture a substantial part of Airspan's product
for resale.

   Stock options are granted under various stock compensation programs to
employees and independent directors. The Company accounts for stock option
grants in accordance with Accounting Principles Board Opinion No. 25
"Accounting for Stock Issued to Employees" ("APB 25"). In rare instances, stock

2. THE ACQUISITION OF THE PREDECESSOR BUSINESS

   The Company was formed simultaneously with the acquisition of the
Predecessor Business which began development of fixed wireless access systems
in 1994. In accordance with the terms of the acquisition, the assets and
liabilities of the Predecessor Business unit were transferred from DSC to the
Company on January 26, 1998.

   As consideration for the sale Airspan issued 10,000,000 shares of Preferred
Series A stock to DSC. Total direct costs relating to the acquisition and the
issuance of venture capital were $675. Of this, $575 has been accounted for as
a reduction in the proceeds of Series A stock as this represents the cost of
issuing the shares. The remaining $100 represents other direct and incremental
acquisition costs and has been included in the cost of the acquisition.

   The purchase price allocation was as follows:

                 NOTES TO THE FINANCIAL STATEMENTS--(Continued)
              (in thousands, except for share and per share data)

   A detailed review was undertaken by management, who have primary
responsibility, to estimate the fair values and remaining economic lives for
all material intangible assets, including any in-process technology, purchased
from DSC Communications Corporation in accordance with "Fair Value" as referred
to in APB Opinion No. 16.

   The amount allocated to in-process research and development was recorded as
a one-time charge to operations in 1998 because the technology was not fully
developed and had no future alternative use. Management's expectations of the
future revenue streams to be generated from this technology meant that a
material amount of the purchase price was allocated to in-process research and
development. The product under development was 80% complete at acquisition,
with an estimated $4.1 million of cost required to complete the project
associated with final development, system verification and test, documentation
and release to manufacturing processes.

   The acquired in-process research and development represents the development
of technologies associated with a new generation of the AS4000 System, which
allows a significantly larger number of subscribers to be supported on a single
radio channel. This project was materially completed by March 31, 1998, with
the first shipment in June 1998 and revenue first recognized in December 1998.

   The appraisal method used to value the in-process technology was the Income
Approach where the valuation is focused on the income-producing capability of
the Demand Assigned product. The premise being that the value of an asset can
be measured by the present worth of the net economic benefit to be received
over the life of the asset. Expected cash flows attributable to the demand
assigned product over its product life cycle were converted to present value
through discounting. The discounting process used a rate of return that
accounted for the time value of money and risk factors.

   The significant assumptions made in the valuation were as follows:

  .  The valuation was performed as at 31 January 1998, the date of
     acquisition, with the knowledge and assumptions held at that date

  .  Revenue streams were expected to commence in the second half of 1998 and
     carry on through to 2003

  .  Average sales prices would be significantly lower than that of the older
     generation product

  .  Forecasted average sales prices and costs of goods relating to the new
     product offering would decrease over the life of the product. The
     product costs decreasing at a greater rate, leading to an improvement in
     margins for future years

  .  Risk adjusted discount factor used was 28%, assessed to be 100 basis
     points greater than the Company's weighted average cost of capital to
     allow for the required return on in-process technology

   The developed technology relates to the older generation product, designed
to provide a fixed network service.

3. TAXATION

   The Company did not record an income tax benefit for the tax losses
generated in the U.K. because it has experienced operating losses since
inception. At December 31, 1999 the Company has U.K. income tax net operating
loss carryforwards of $47,918 which do not expire.

   Since the Company's utilization of these deferred tax assets is dependent on
future profits, a valuation allowance equal to the net deferred tax assets has
been provided following the criteria under SFAS 109 as it is considered more
likely than not that such assets will not be realised.

   On January 30, 1998 the Company issued a promissory note with a principal
amount of $17,000 and an interest rate of 7% per annum to DSC Telcom L.P. The
principal amount of the promissory note was subsequently adjusted down by
$1,984 with an effective adjustment date of January 30, 1998, due to a purchase
price adjustment applicable to certain customer contracts. Accrued but unpaid
interest is considered additional principal and is added to the principal
indebtedness every quarter commencing April 15, 1998.

   The promissory note bearing interest at 7% is repayable in 36 equal monthly
installments commencing February 1, 2001. In the event that the principal
amount payable under the promissory note is adjusted further, the amount of the
equal installments shall be recalculated from the date of the adjustment so
that the principal is paid in equal installments over the remainder of the
thirty-six month period. The amount payable under the promissory note is still
under negotiation whereby the company is seeking to reduce the principal to be
paid as a result of certain claims against DSC in connection with the
acquisition.

   On March 19, 1999 the Company entered into two Loan Agreements to borrow
$2,500 in installments of $1,250 each. The Company executed the borrowing of
$1,250 against this Loan Agreement on March 29, 1999 as evidenced by the issue
of a promissory note. The promissory note is repayable in 30 equal monthly
installments of $46 commencing May 1, 1999 and two additional final
installments of $94 to be paid on October 1, 2001 and May 1, 2002. The
promissory note has an interest rate of 9% per annum.

   On March 19, 1999 the Company also entered into a subordinated loan and
security agreement to borrow $3,750 in increments of $1,250 each. The loan was
executed by the Company on March 29, 1999 by the issue of three subordinated
promissory notes of $1,250. Two of the subordinated promissory notes have the

10. STOCK OPTIONS

   On February 1, 1998, and as subsequently amended, the Board of Directors
authorized the establishment of a non-qualified employee stock option plan
whereby the Company may grant employees stock options to purchase up to
2,791,667 shares of common stock. The exercise price of each option is equal to
the market price of the Company's common stock on the date of grant, as
determined by the Board of Directors of the Company. Employee stock options
generally vest over a four-year period and expire on the tenth anniversary of
their issuance. The total number of options granted were 1,237,167 and
1,779,500 and 2,007,334 as of December 31, 1998, December 31, 1999 and April 2,
2000, respectively, to employees under the plan.

   Also, within the plan described above, the Company granted nonqualified
common stock options to directors under various discrete option agreements. The
number of non-qualified options granted to directors were 500,000 and 596,666
and 596,666 as of December 31, 1998, December 31, 1999 and April 2, 2000,
respectively.

   The Company has a full recourse note receivable from a director relating to
the exercise of such options in the amount of $150 outstanding at December 31,
1998 and $130 outstanding at December 31, 1999 and April 2, 2000. Such options
may be exercised for the issuance of restricted stock to the extent such
options are not vested. Restrictions lapse over the same four year vesting
schedule as the underlying option. In the event of termination, the Company has
a repurchase right determined on the original exercise price.

   The Company granted options to purchase 14,000 shares of common stock to
consultants at an exercise price of $0.30 per share in February 1998. In
December 1999 the Company granted options to purchase 5,000 shares of common
stock to a consultant at an exercise price of $6.00 per share. These options
were granted in exchange for consulting services. The Company valued these
options using the Black-Scholes option-pricing model. As such, $4 was charged
to operations in 1998, $93 was charged to operations in 1999 and $25 was
charged to operations in the quarter ended April 2, 2000 to reflect the
estimated fair value of the underlying options. All such options remain
unexercised as of December 31, 1998, December 31, 1999 and April 2, 2000.

   The Company applies APB 25 in accounting for its stock options and warrants.
On a pro forma basis, had compensation cost been determined on the basis of
fair value determined under the minimum value method pursuant to SFAS 123, net
loss would have been as follows for the periods ended December 31, 1998 and
December 31, 1999:

   The weighted average fair value of the options at their grant date was $0.06
during 1998 and $0.60 during 1999. The estimated fair value of each option
granted is calculated using the Black-Scholes option-pricing model. The
following summarizes the weighted average of the assumptions used in the model:

11. CONVERTIBLE PREFERRED STOCK

   The holders of the $1.00 Series A Convertible Preferred Stock (Series A
Stock) and $1.75 Series B Convertible Preferred Stock (Series B Stock) and
$2.50 Series C Convertible Preferred Stock (Series C Stock) are entitled to
receive dividends, on an as-converted basis, if and when any such dividend is
paid on the Common Stock, by declaration of the Board of Directors. No
dividends have been declared.

   Upon any liquidation, dissolution or winding up of Airspan, the holders of
the Series A Stock, Series B Stock and Series C Stock will be entitled to
receive, from Airspan's assets available for distributions to stockholders,
$1.00 for each outstanding share of the Series A Stock, $1.75 for each
outstanding share of the Series B Stock, and $2.50 for each outstanding share
of Series C Stock plus all dividends accrued, on a pari passu basis, before any
distribution is made to the Common stockholders. After such payment and
distribution to any other class or series of preferred stock, the holders of
the Convertible Preferred Stock would be entitled to further distributions of
remaining assets on a pari passu basis.

   The Series A Stock, Series B Stock and Series C Stock is convertible into
Common Stock at any time after issuance. Except under the conditions described
below the Convertible Preferred Stock are converted to Common Stock on a three
for one basis. This conversion factor would be adjusted ratably if any
subsequent issues of Common Stock or Convertible Preferred Stock are at a lower
per share consideration than the Series A, B and C convertible preferred stock
already in issue. The Series A Stock, Series B Stock and Series C Stock would
be automatically converted to common stock upon the closing of a qualified
initial public offering. The Series A Stock, Series B Stock and Series C Stock
are not redeemable.

   The holders of each share of the Series A Stock, Series B Stock and Series C
Stock have the right to one vote for each share of Common Stock into which each
such share of Series A Stock, Series B Stock and Series C Stock could then be
converted. The voting rights of Convertible Preferred Stock are the same as the
rights of the holders of the Common Stock.

12. STOCK WARRANTS

   As of December 31, 1999, in addition to the option plans discussed above,
Airspan has various warrants outstanding to purchase 249,998 shares of the
Company's Series B Convertible Preferred Stock at exercise prices of $1.75 per
share which were issued in connection with debt facilities and lease
agreements. As of December 31, 1999 all of these warrants are currently
exercisable. These warrants expire on the earlier of seven years from the
effective date of the warrant agreement or three years from the effective date
of the Company's initial public offering. Upon the completion of a qualified
initial public offering these warrants would convert to common stock warrants.
The number of shares of Common Stock to be obtained upon exercise of certain of
these warrants are

              (in thousands, except for share and per share data)

subject to adjustment under certain conditions. The estimated fair value of the
warrants, determined based on the Black-Scholes valuation model was $95. The
value of these warrants was recorded as deferred loan costs and are amortized
over the life of the loan.

13. NET LOSS PER SHARE

   Net loss per share is computed using the weighted average number of shares
of common stock outstanding less the number of shares subject to repurchase.
Shares associated with stock options, warrants and the convertible preferred
stock are not included in the calculation of diluted net loss per share because
they are antidilutive. As described above, each share of convertible preferred
stock will automatically convert to common stock upon the completion of the
company's initial public offering. Pro forma net loss per share data has been
determined as if each share of convertible preferred stock had converted to
common stock at the time of issuance.

   The following table sets forth the computation of basic and diluted net loss
per share and pro forma basic and diluted net loss per share for the periods
indicated:

options, 249,998 Series B Convertible stock warrants and 80,171,429 shares of
convertible preferred stock outstanding at April 2, 2000 that were excluded
from the computation of diluted net loss per share as their effect was
antidilutive. If the Company had reported net income, the calculation of these
per share amounts would have included the dilutive effect of these common stock
equivalents using the treasury stock method for stock options and warrants
using the if converted method for convertible preferred stock.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

   Section 5.4 of our Articles of Incorporation authorizes us to indemnify any
present or former director or officer to the fullest extent not prohibited by
the Washington Business Corporation Act ("WBCA") or other applicable law now or
hereafter in force. Chapter 23B.08.510 and .570 of the WBCA authorizes a
corporation to indemnify its directors, officers, employees, or agents in terms
sufficiently broad to permit such indemnification under certain circumstances
for liabilities (including provisions permitting advances for expenses
incurred) arising under the Securities Act.

   In addition, we maintain directors' and officers' liability insurance under
which our directors and officers are insured against loss (as defined in the
policy) as a result of claims brought against them for their wrongful acts in
such capacities.

report thereon dated February 9, 2000, except for Note 16--Subsequent Events,
as to which the date is May 26, 2000 (included elsewhere in this Registration
Statement). Our audits also included the financial statement schedule listed in
Item 16(b) of this Registration Statement. This schedule is the responsibility
of the Company's management. Our responsibility is to express an opinion based

ITEM 17. UNDERTAKINGS

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

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

                             AIRSPAN NETWORKS INC.

                                   ARTICLE 1

                                      NAME

     The name of this corporation is Airspan Networks Inc.

                                   ARTICLE 2

                                    DURATION

     This corporation is organized under the Washington Business Corporation Act
(the "Act") and shall have perpetual existence.

                                   ARTICLE 3

                               PURPOSE AND POWERS

     The purpose and powers of this corporation are as follows:

     3.1  To engage in any lawful business.

     3.2  To engage in any and all activities that, in the judgment of the Board
of Directors, may at any time be incidental or conducive to the attainment of
the foregoing purpose.

     3.3  To exercise any and all powers that a corporation formed under the

                                   ARTICLE 4

                                 CAPITAL STOCK
<PAGE>

     4.1  Classes and Series of Stock. This corporation is authorized to issue
two classes of stock, to be designated, respectively, "Common Stock" and
"Convertible Preferred Stock." The total number of shares that this corporation
is authorized to issue is one hundred thirty-six million (136,000,000) shares.
Fifty million (50,000,000) shares shall be Common Stock, par value $.0003 per
share, and eighty-six million (86,000,000) shares shall be Convertible Preferred
Stock, par value $.0001 per share. The Convertible Preferred Stock shall include
three series as follows: forty million (40,000,000) shares of Series A
Convertible Preferred Stock (the "Series A Stock"); eighteen million eight
hundred twenty-one thousand four hundred twenty-seven (18,821,427) shares of
Series B Convertible Preferred Stock (the "Series B Stock"); and twenty-two
million one hundred seventy eight thousand five seventy-three (22,178,573)
shares of Series C Convertible Preferred Stock (the "Series C Stock"). Authority
is vested in the Board of Directors, subject to the limitations and procedures
prescribed by law, to divide any part or all of such preferred class into any
number of series, to fix and determine relative rights and preferences of the
shares of any series to be established, and to amend the rights and preferences
of the shares of any series that has been established but is wholly unissued.

     Within any limits stated in these Articles or in the resolution of the
Board of Directors establishing a series, the Board of Directors, after the
issuance of shares of a series, may amend the resolution establishing the series
to decrease (but not below the number of shares of such series then outstanding)
the number of shares of that series, and the number of shares constituting the
decrease shall thereafter constitute authorized but undesignated shares.

     The authority herein granted to the Board of Directors to determine the
relative rights and preferences of the preferred stock shall be limited to
unissued shares, and no power shall exist to alter or change the rights and
preferences of any shares that have been issued.

     4.2  Rights, Preferences and Restrictions of Convertible Preferred Stock.
The rights, preferences, privileges, and restrictions granted to and imposed on
the Series A Stock, Series B Stock and Series C Stock are as set forth below in
this Section 4.2.

          4.2.1  Dividend Provision. The holders of shares of Series A Stock,
Series B Stock and Series C Stock shall be entitled to receive dividends, on an
as-converted basis, when and if any such dividend is paid on the Common Stock by
declaration of the Board of Directors.

          4.2.2  Liquidation Preference.

                 (a)  In the event of any liquidation, dissolution or winding up
of this corporation, either voluntary or involuntary, subject to the rights of
other classes or series of preferred stock that may from time to time come into
existence, the holders of Series A Stock, Series B Stock and Series C Stock
shall be entitled to receive, prior and in preference to any distribution of any
of the assets of this corporation to the holders of

                                       2
<PAGE>

Common Stock by reason of their ownership thereof, an amount per share equal to
the sum of (i) $1.00 for each outstanding share of Series A Stock (the "Original
Series A Issue Price"), $1.75 for each outstanding share of Series B Stock (the
"Original Series B Issue Price"), and $2.50 for each outstanding share of Series
C Stock (the "Original Series C Issue Price," and together with the Original
Series A Issue Price and the Original Series B Issue Price, the "Original Issue
Price"), and (ii) an amount equal to declared but unpaid dividends on each such
share of Series A Stock, Series B Stock and Series C Stock. If upon the
occurrence of such event, the assets and funds thus distributed among the
holders of the Series A Stock, Series B Stock and Series C Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, subject to the rights of other classes or series of
preferred stock that may from time to time come into existence, the entire
assets and funds of this corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Stock, Series B Stock and
Series C Stock in proportion to the preferential amount each such holder is
otherwise entitled to receive.

               (b)  For purposes of subsections (c), (d), (e) and (f) of this
Section 4.2.2, the following definitions shall apply:

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

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

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

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

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

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

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

               (c)  Upon the completion of the distributions required by
subsection (a) of this Section 4.2.2 and any other distribution that may be
required with respect to any other class or series of preferred stock that may
from time to time come into existence, the remaining assets of this corporation
legally available for distribution to stockholders shall be distributed as
follows: (i) an aggregate amount (the "Second Distribution Amount") equal to the
product of $2.00 multiplied by the number of shares of Series A Stock, Series B
Stock and Series C Stock then outstanding shall be

                                       3
<PAGE>

distributed, on a pari passu basis, in an amount equal to the Series A
Percentage multiplied by the Second Distribution Amount, ratably among the
holders of Series A Preferred Stock, in an amount equal to the Series B
Percentage multiplied by the Second Distribution Amount, ratably among the
holders of Series B Preferred Stock, and in an amount equal to the Series C
Percentage multiplied by the Second Distribution Amount, ratably among the
holders of Series C Preferred Stock, and (ii) an amount per share equal to $2.00
for each outstanding share of Common Stock shall be distributed ratably among
the holders of Common Stock. If the assets and funds thus distributed among the
holders of the Series A Stock, Series B Stock, Series C Stock and the Common
Stock shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then, subject to the rights of any other class
or series of preferred stock that may from time to time come into existence, the
entire assets and funds of this corporation legally available for distribution
shall be distributed ratably among the holders of the Series A Stock, Series B
Stock, Series C Stock and Common Stock in proportion to the amount each such
holder is otherwise entitled to receive under this subsection (c).

               (d)  Upon the completion of the distributions required by
subsections (a) and (c) of this Section 4.2.2 and any other distribution that
may be required with respect to any other class or series of preferred stock
that may from time to time come into existence, the remaining assets of this
corporation legally available for distribution to stockholders shall be
distributed as follows: (i) an aggregate amount (the "Third Distribution
Amount") equal to the product of $1.50 multiplied by the number of shares of
Series B Stock and Series C Stock then outstanding shall be distributed, on a
pari passu basis, in an amount equal to the Series A Percentage multiplied by
the Third Distribution Amount, ratably among the holders of Series A Stock, in
an amount equal to the Series B Percentage multiplied by the Third Distribution
Amount, ratably among the holders of Series B Preferred Stock, and in an amount
equal to the Series C Percentage multiplied by the Third Distribution Amount,
ratably among the holders of Series C Preferred Stock, and (ii) an amount per
share equal to $1.50 for each outstanding share of Common Stock, in addition to
the amounts paid pursuant to subsection (c) of this Section 4.2.2, shall be
distributed ratably among the holders of Common Stock. If the assets and funds
thus distributed among the holders of the Series A Stock, Series B Stock, Series
C Stock and Common Stock shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amount, then, subject to the rights
of any other class or series of preferred stock that may from time to time come
into existence, the entire assets and funds of this corporation legally
available for distribution shall be distributed ratably among the holders of the
Series A Stock, Series B Stock, Series C Stock and Common Stock in proportion to
the amount each such holder is otherwise entitled to receive under this
subsection (d).

               (e)  Upon the completion of the distributions required by
subsections (a), (c) and (d) of this Section 4.2.2 and any other distribution
that may be required with respect to any other class or series of preferred
stock that may from time to time come into existence, the remaining assets of
this corporation legally available for distribution to stockholders shall be
distributed as follows: (i) an aggregate amount (the "Fourth Distribution
Amount") equal to the product of $1.50 multiplied by the number of

                                       4
<PAGE>

shares of Series C Stock then outstanding shall be distributed, on a pari passu
basis, in an amount equal to the Series A Percentage multiplied by the Fourth
Distribution Amount, ratably among the holders of Series A Stock, in an amount
equal to the Series B Percentage multiplied by the Fourth Distribution Amount,
ratably among the holders of Series B Preferred Stock, and in an amount equal to
the Series C Percentage multiplied by the Fourth Distribution Amount, ratably
among the holders of Series C Preferred Stock, and (ii) an amount per share
equal to $1.50 for each outstanding share of Common Stock, in addition to the
amounts paid pursuant to subsections (c) and (d) of this Section 4.2.2, shall be
distributed ratably among the holders of Common Stock. If the assets and funds
thus distributed among the holders of the Series A Stock, Series B Stock, Series
C Stock and Common Stock shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amount, then, subject to the rights
of any other class or series of preferred stock that may from time to time come
into existence, the entire assets and funds of this corporation legally
available for distribution shall be distributed ratably among the holders of the
Series A Stock, Series B Stock, Series C Stock and Common Stock in proportion to
the amount each such holder is otherwise entitled to receive under this
subsection (e).

               (f)  Upon the completion of the distributions required by
subsections (a), (c), (d) and (e) of this Section 4.2.2 and any other
distribution that may be required with respect to any other class or series of
preferred stock that may from time to time come into existence, if assets remain
in this corporation, the holders of Series A Stock, Series B Stock and Series C
Stock shall receive no further distributions and the holders of the Common Stock
of this corporation shall receive all of the remaining assets of this
corporation pro rata based on the number of shares of Common Stock held by each.

               (g)  (i)  For purposes of this Section 4.2.2, unless otherwise
agreed by holders of at least sixty-seven percent (67%) of the then outstanding
shares of Series A Stock, Series B Stock and Series C Stock, voting together as
a single class and not as a separate series, on an as-converted basis, a
liquidation, dissolution or winding up of this corporation shall be deemed to be
occasioned by, or to include, (A) any consolidation or merger of the corporation
with or into any other corporation or entity or person, or any other corporate
reorganization in which shareholders of the corporation immediately prior to
such consolidation, merger or reorganization, as a result of their ownership of
the corporation's securities, own less than 50% of the surviving corporation's
voting power immediately after such consolidation, merger or reorganization; or
(B) a sale, lease or other disposition of all or substantially all of the assets
of this corporation.

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

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

                                       5
<PAGE>

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

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

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

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

                   (iii)   In the event the requirements of this subsection
4.2.2(g) are not complied with, this corporation shall forthwith either:

                           (A)    cause such closing to be postponed until such
time as the requirements of this Section 4.2.2 have been complied with; or

                           (B)    cancel such transaction, in which event the
rights, preferences and privileges of the holders of the Series A Stock, Series
B Stock and Series C Stock shall revert to and be the same as such rights,
preferences and privileges existing immediately prior to the date of the first
notice referred to in subsection 4.2.2(g)(iv) hereof.

                   (iv)    This corporation shall give each holder of record of
Series A Stock, Series B Stock and Series C Stock written notice of such
impending transaction not later than twenty (20) days prior to the stockholders'
meeting called to approve such transaction, if any, or twenty (20) days prior to
the closing of such transaction, whichever is earlier, and shall also notify
such holders in writing of the final approval of such transaction. The first of
such notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 4.2.2, and this corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than twenty (20) days after this
corporation has given the first notice provided for herein or sooner than ten
(10) days after this corporation has given notice of any material changes
provided for

                                       6
<PAGE>

herein; provided, however, that such periods may be shortened upon the written
consent of the holders of Convertible Preferred Stock that are entitled to such
notice rights or similar notice rights and that represent at least a majority of
the voting power of all then outstanding shares of such Series A Stock, Series B
Stock and Series C Stock, voting together as a single class.

          4.2.3  Redemption. The Series A Stock, Series B Stock and Series C
Stock are not redeemable.

          4.2.4  Conversion. The holders of the Series A Stock, Series B Stock
and Series C Stock shall have conversion rights as follows (the "Conversion
Rights"):

                 (a)    Right to Convert. Each share of Series A Stock, Series B
                        ----------------
Stock and Series C Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
this corporation or any transfer agent for such stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing the
Original Issue Price (as defined above) applicable to such series by the
Conversion Price (as defined below) applicable to such series, determined as
hereafter provided, in effect on the date the certificate is surrendered for
conversion. The initial "Conversion Price" per share for shares of Series A
Stock shall be the Original Series A Issue Price; the initial "Conversion Price"
per share for shares of Series B Stock shall be the Original Series B Issue
Price; and the initial "Conversion Price" per share for shares of Series C Stock
shall be the Original Series C Issue Price; provided, however, that the
Conversion Price for the Series A Stock, Series B Stock and Series C Stock shall
be subject to adjustment as set forth in subsection 4.2.4(d) hereof.

                 (b)    Automatic Conversion. Each share of Series A Stock,
                        --------------------
Series B Stock and Series C Stock shall automatically be converted into shares
of Common Stock at the Conversion Price at the time in effect for such series
immediately upon the earlier of (i) this corporation's sale of its Common Stock
in a firm commitment underwritten public offering pursuant to a registration
statement on Form S-1 or Form SB-2 under the Securities Act of 1933, as amended,
the public offering price of which was not less than $5.25 per share (adjusted
to reflect subsequent stock dividends, stock splits or recapitalizations) and
the aggregate offering proceeds of which were not less than $40,000,000 (net of
underwriting discounts and commissions) or (ii) the date specified by written
consent or agreement of the holders of seventy-five percent (75%) of the then
outstanding shares of Series A Stock, Series B Stock and Series C Stock, voting
together as a single class on an as-converted basis and not as separate series.

                 (c)    Mechanics of Conversion. Before any holder of Series A
                        -----------------------
Stock, Series B Stock or Series C Stock shall be entitled to convert the same
into shares of Common Stock, he or she shall surrender the certificate or
certificates therefor, duly endorsed, at the office of this corporation or of
any transfer agent for the Series A Stock, Series B Stock or Series C Stock, and
shall give written notice to this corporation at its principal corporate office
of the election to convert the same and shall state therein the name or names in
which the certificate or certificates for shares of

                                       7
<PAGE>

Common Stock are to be issued. This corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series A Stock,
Series B Stock or Series C Stock, or to the nominee or nominees of such holder,
a certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series A Stock, Series B Stock or Series C Stock to
be converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act of 1933, as amended, the conversion
may, at the option of any holder tendering Series A Stock, Series B Stock or
Series C Stock for conversion, be conditioned upon the closing with the
underwriters of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive the Common Stock upon conversion of the Series
A Stock, Series B Stock or Series C Stock shall not be deemed to have converted
such Series A Stock, Series B Stock or Series C Stock until immediately prior to
the closing of such sale of securities.

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

                        (i)  (A)  If this corporation shall issue, after the
date upon which any shares of Series C Stock were first issued (the "Purchase
Date"), any Additional Stock (as defined below) without consideration or for a
consideration per share less than the Conversion Price for the Series A Stock,
Series B Stock or Series C Stock (the "Affected Series") in effect immediately
prior to such issuance, then the Conversion Price of each Affected Series in
effect immediately prior to such issuance shall forthwith (except as otherwise
provided in this clause (i)) be adjusted to a price determined by multiplying
such Conversion Price of the Affected Series by a fraction, the numerator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issuance (including shares of Common Stock deemed to be issued
pursuant to subsection 4.2.4(d)(i)(E)(1) or (2)) plus the number of shares of
Common Stock that the aggregate consideration received by this corporation for
such issuance would purchase at such Conversion Price; and the denominator of
which shall be the number of shares of Common Stock outstanding immediately
prior to such issuance (including shares of Common Stock deemed to be issued
pursuant to subsection 4.2.4(d)(i)(E)(1) or (2)) plus the number of shares of
such Additional Stock.

                             (B)  No adjustment of the Conversion Price for the
Series A Stock, Series B Stock or Series C Stock shall be made in an amount less
than one cent per share, provided that any adjustments that are not required to
be made by reason of this sentence shall be carried forward and shall be either
taken into account in any subsequent adjustment to the Conversion Price of the
Affected Series made prior to three (3) years from the date of the event giving
rise to the adjustment being carried forward, or shall be made at the end of
three (3) years from the date of the event giving

                                       8
<PAGE>

rise to the adjustment being carried forward. Except to the limited extent
provided for in subsections (E)(3) and (E)(4), no adjustment of such Conversion
Price of the Series A Stock, Series B Stock or Series C Stock pursuant to this
subsection 4.2.4(d)(i) shall have the effect of increasing the Conversion Price
of the Affected Series above the Conversion Price in effect immediately prior to
such adjustment.

                             (C)  In the case of the issuance of Common Stock
for cash, the consideration shall be deemed to be the amount of cash paid
therefor before deducting any reasonable discounts, commissions or other
expenses allowed, paid or incurred by this corporation for any underwriting or
otherwise in connection with the issuance and sale thereof.

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

                             (E)  In the case of the issuance (whether before,
on or after the Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this subsection 4.2.4(d)(i) and subsection 4.2.4(d)(ii).

                                  (1)  The aggregate maximum number of shares of
Common Stock deliverable upon exercise (assuming the satisfaction of any
conditions to exercisability, including, without limitation, the passage of
time, but without taking into account potential antidilution adjustments) of
such options to purchase or rights to subscribe for Common Stock shall be deemed
to have been issued at the time such options or rights were issued and for a
consideration equal to the consideration (determined in the manner provided in
subsections 4.2.4(d)(i)(C) and (d)(i)(D)), if any, received by this corporation
upon the issuance of such options or rights plus the minimum exercise price
provided in such options or rights (without taking into account potential
antidilution adjustments) for the Common Stock covered thereby.

                                  (2)  The aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange (assuming the
satisfaction of any conditions to convertibility or exchangeability, including,
without limitation, the passage of time, but without taking into account
potential antidilution adjustments) for any such convertible or exchangeable
securities or upon the exercise of options to purchase or rights to subscribe
for such convertible or exchangeable securities and subsequent conversion or
exchange thereof shall be deemed to have been issued at the time such securities
were issued or such options or rights were issued and for a consideration equal
to the consideration, if any, received by this corporation for any such
securities and related options or rights (excluding any cash received on account
of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by this corporation (without taking into

                                       9
<PAGE>

account potential antidilution adjustments) upon the conversion or exchange of
such securities or the exercise of any related options or rights (the
consideration in each case to be determined in the manner provided in
subsections 4.2.4(d)(i)(C) and (d)(i)(D)).

                                       (3)  In the event of any change in the
number of shares of Common Stock deliverable or in the consideration payable to
this corporation upon exercise of such options or rights or upon conversion of
or in exchange for such convertible or exchangeable securities, including, but
not limited to, a change resulting from the antidilution provisions thereof
(unless such options or rights or convertible or exchangeable securities were
merely deemed to be included in the numerator and denominator for purposes of
determining the number of shares of Common Stock outstanding for purposes of
subsection 4.2.4(d)(i)(A)), the Conversion Price of the Series A Stock, Series B
Stock or Series C Stock, to the extent in any way affected by or computed using
such options, rights or securities, shall be recomputed to reflect such change,
but no further adjustment shall be made for the actual issuance of Common Stock
or any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                                       (4)  Upon the expiration of any such
options or rights, the termination of any such rights to convert or exchange or
the expiration of any options or rights related to such convertible or
exchangeable securities, the Conversion Price of the Series A Stock, Series B
Stock or Series C Stock, to the extent in any way affected by or computed using
such options, rights or securities or options or rights related to such
securities (unless such options or rights were merely deemed to be included in
the numerator and denominator for purposes of determining the number of shares
of Common Stock outstanding for purposes of subsection 4.2.4(d)(i)(A)), shall be
recomputed to reflect the issuance of only the number of shares of Common Stock
(and convertible or exchangeable securities that remain in effect) actually
issued upon the exercise or such options or rights, upon the conversion or
exchange of such securities or upon the exercise of the options or rights
related to such securities.

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

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

                                (A)    Common Stock issuable or issued pursuant
to a transaction described in subsection 4.2.4(d)(iii) hereof;

                                (B)    shares of Common Stock issuable or issued
to employees, consultants or directors of this corporation directly or pursuant
to a stock option plan or restricted stock plan approved by the Board of
Directors of this

                                      10
<PAGE>

corporation;

                                (C)    shares of Common Stock issuable or issued
in a firm commitment underwritten public offering before or in connection with
which all outstanding shares of Series A Stock, Series B Stock and Series C
Stock will be converted to Common Stock;

                                (D)    shares of Common Stock issuable or issued
upon conversion of the Series A Stock, Series B Stock or Series C Stock or other
already outstanding convertible securities (including shares issuable or issued
as a result of the antidilution provisions thereof), or as dividends or
distributions on the Series A Stock, Series B Stock or Series C Stock;

                                (E)    shares of Common Stock issuable or issued
upon exercise of warrants issued to banks or equipment lessors, which warrants
were approved by the Board of Directors; or

                                (F)    shares of Common Stock issuable or issued
in connection with business combinations or corporate partnering agreements
approved by the Board of Directors.

                        (iii)   In the event this corporation should at any time
or from time to time after the Purchase Date fix a record date for the
effectuation of a split or subdivision of the outstanding shares of Common Stock
or the determination of holders of Common Stock entitled to receive a dividend
or other distribution payable in additional shares of Common Stock or other
securities or rights convertible into, or entitling the holder thereof to
receive directly or indirectly, additional shares of Common Stock (hereinafter
referred to as "Common Stock Equivalents") without payment of any consideration
by such holder for the additional shares of Common Stock or the Common Stock
Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such dividend distribution, split or subdivision if no record date is fixed),
the Conversion Price of the Series A Stock, Series B Stock and Series C Stock
shall be appropriately decreased so that the number of shares of Common Stock
issuable on conversion of each share of such series shall be increased in
proportion to such increase of the aggregate of shares of Common Stock
outstanding and those issuable with respect to such Common Stock Equivalents.

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

                                      11
<PAGE>

        (e)  Other Distributions.  In the event this corporation shall declare a
             -------------------
distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (excluding cash dividends)
or options or rights not referred to in subsection 4.2.4(d)(iii), then, in each
such case for the purpose of this subsection 4.2.4(e), the holders of the Series
A Stock, Series B Stock and Series C Stock shall be entitled to a proportionate
share of any such distribution as though they were the holders of the number of
shares of Common Stock of this corporation into which their shares of Series A
Stock, Series B Stock and Series C Stock are convertible as of the record date
fixed for the determination of the holders of Common Stock of this corporation
entitled to receive such distribution.

        (f)  Recapitalizations. If at any time or from time to time there shall
             -----------------
be a recapitalization of the Common Stock (other than a subdivision, combination
or merger or sale of assets transaction provided for elsewhere in this Section
4.2.4 or in Section 4.2.2) provision shall be made so that the holders of the
Series A Stock, Series B Stock and Series C Stock shall thereafter be entitled
to receive upon conversion of the Series A Stock, Series B Stock and Series C
Stock the number of shares of stock or other securities or property of this
corporation or otherwise to which a holder of Common Stock deliverable upon
conversion would have been entitled on such recapitalization. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 4.2.4 with respect to the rights of the holders of the Series A
Stock, Series B Stock and Series C Stock after the recapitalization to the end
that the provisions of this Section 4.2.4 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of the Series A Stock, Series B Stock and Series C Stock) shall be
applicable after that event as nearly equivalent as may be practicable.

        (g)  No Impairment. This corporation will not, by amendment of its
             -------------
Amended and Restated Articles of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by this corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4.2.4 and in the taking of
all such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of the Series A Stock, Series B Stock and
Series C Stock against impairment.

        (h)  No Fractional Shares and Certificate as to Adjustments.
             ------------------------------------------------------

             (i) No fractional shares shall be issued upon the conversion of any
share or shares of the Series A Stock, Series B Stock or Series C Stock, and the
number of shares of Common Stock to be issued shall be determined by rounding to
the nearest whole share. Such conversion shall be determined on the basis of the
total number of shares of Series A Stock, Series B Stock and Series C Stock the
holder is at the time converting into Common Stock and such rounding shall apply
to the number of shares of Common Stock issuable upon such aggregate conversion.

                                       12
<PAGE>

             (ii)  Upon the occurrence of each adjustment or readjustment of the
Conversion Price of the Series A Stock, Series B Stock or Series C Stock
pursuant to this Section 4.2.4, this corporation, at its expense, shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
prepare and furnish to each holder of the Affected Series a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. This corporation shall, upon the
written request at any time of any holder of Series A Stock, Series B Stock or
Series C Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (A) such adjustment and readjustment, (B) the
Conversion Price for such series of Convertible Preferred Stock at the time in
effect and (C) the number of shares of Common Stock and the amount, if any, of
other property that at the time would be received upon the conversion of a share
of Series A Stock, Series B Stock or Series C Stock, as the case may be.

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

        (j)  Reservation of Stock Issuable Upon Conversion. This corporation
             ---------------------------------------------
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A Stock, Series B Stock and Series C Stock, such number
of its shares of Common Stock as shall from time to time be sufficient to effect
the conversion of all outstanding shares of the Series A Stock, Series B Stock
and Series C Stock; and if at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient to effect the conversion of all
then outstanding shares of the Series A Stock, Series B Stock and Series C
Stock, in addition to such other remedies as shall be available to the holder of
such Series A Stock, Series B Stock and Series C Stock, this corporation will
take such corporate action as may, in the opinion of its counsel, be necessary
to increase its authorized but unissued shares of Common Stock to such number of
shares as shall be sufficient for such purposes, including, without limitation,
engaging in best efforts to obtain the requisite stockholder approval of any
necessary amendment to this Certificate of Incorporation.

        (k)  Notices. Any notice required by the provisions of this Section
             -------
4.2.4 to be given to the holders of shares of Series A Stock, Series B Stock or
Series C Stock shall be deemed given if deposited in the United States mail,
postage prepaid, and addressed to each holder of record at his, her or its
address appearing on the books of this corporation.

                                       13

        (l)  Special Mandatory Conversion.
             ----------------------------

             (i)  If (A) this corporation consummates a financing (a
"Financing") pursuant to which any holders of Series A Stock, Series B Stock and
Series C Stock are entitled to exercise the first right of refusal (the "First
Right of Refusal") set forth in Section 2.4 of the Second Amended and Restated
Investors' Rights Agreement, dated on or about November 1, 1999, by and among
this corporation and certain investors and persons, and as it may be further
amended from time to time (the "Rights Agreement"); (B) the Board of Directors
of this corporation shall have determined that holders of Series A Stock, Series
B Stock and Series C Stock of this corporation must participate in the Financing
(a "Mandatory Offering") and have determined the aggregate dollar amount to be
invested by all holders of Series A Stock, Series B Stock and Series C Stock
(the "Aggregate Preferred Stock Investment Amount"), which amount may be more
than or less than the holders' right to participate in the Financing pursuant to
the First Right of Refusal contained in the Rights Agreement and which amount
shall not exceed twenty-five million dollars ($25,000,000); (C) this corporation
shall have delivered a notice ("Notice") to the holders of Series A Stock,
Series B Stock and Series C Stock: (1) stating this corporation's bona fide
intention to consummate the Financing, (2) indicating the number of securities
to be offered, (3) indicating the price and terms upon which it proposes to
offer such securities, (4) identifying the Pro Rata Share (as defined below) of
each holder of Series A Stock, Series B Stock and Series C Stock of the
Aggregate Preferred Stock Investment Amount and (5) offering each holder of
Series A Stock, Series B Stock and Series C Stock the right to purchase such
holder's Pro Rata Share of the Aggregate Preferred Stock Investment Amount
within the time periods set forth in the Notice; and (D) a holder (a "Non-
Participating Holder") does not acquire or does not cause an affiliate to
acquire at least its Pro Rata Share of the Aggregate Preferred Stock Investment
Amount within the time periods set forth in the Notice, then that percentage of
each Non-Participating Holder's shares of Series A Stock, Series B Stock and
Series C Stock equal to the percentage of such Non-Participating Holder's Pro
Rata share of the Aggregate Preferred Stock Investment Amount not acquired by
such Non-Participating Holder shall automatically and without further action on
the part of such holder be converted effective upon, subject to, and
concurrently with, the consummation of the Mandatory Offering (the "Mandatory
Offering Date") into shares of Common Stock of this corporation at a Conversion
Price equal to the Original Series A Issue Price or the Original Series B Issue
Price or the Original Series C Issue Price, as applicable (as adjusted for any
stock dividends, combinations or splits). For purposes of this subsection
4.2.4(I)(i), each holder's Pro Rata Share of the Aggregate Preferred Stock
Investment Amount shall be an amount determined by multiplying the Aggregate
Preferred Stock Investment Amount by a fraction, the numerator of which shall be
the number of shares of Common Stock issuable upon conversion of shares of
Series A Voting Stock, Series B Voting Stock and Series C Voting Stock (as each
term is defined below) then held by such holder and the denominator of which
shall be the total number of shares of Common Stock issuable upon conversion of
shares of Series A Voting Stock, Series B Voting Stock and Series C Voting Stock
then outstanding. For purposes of calculating a holder's Pro Rata Share, the
applicable number of shares of Common Stock issuable upon conversion of the
shares of Series A Voting Stock,

                                       14
<PAGE>

Series B Voting Stock and Series C Voting Stock shall be calculated based on the
number of shares outstanding immediately preceding the closing of the Mandatory
Offering, but assuming a conversion price based on full participation of all of
the holders of Preferred Stock in such Mandatory Offering. The foregoing
notwithstanding, under no circumstances shall any holder of Series A Stock,
Series B Stock or Series C Stock or Common Stock be required to make any
additional investment in a Financing if any of the securities offered in such a
Financing would be rendered non-voting by application of the Legal Limitations
(as defined below) or if any Series A Voting Stock, Series B Voting Stock,
Series C Voting Stock or Voting Common Stock (as each term is defined below)
held by such holder prior to investment in such Financing would be rendered non-
voting by application of the Legal Limitations as a result of such additional
investment in the Financing.

                 (ii)   The holder of any shares of Series A Stock, Series B
Stock or Series C Stock converted pursuant to this subsection 4.2.4(l) shall
deliver to this corporation during regular business hours at the office of any
transfer agent of this corporation for the Series A Stock, Series B Stock or
Series C Stock, or at such other place as may be designated by this corporation,
the certificate or certificates for the shares so converted, duly endorsed or
assigned in blank or to this corporation. As promptly as practicable thereafter,
this corporation shall issue and deliver to such holder, at the place designated
by such holder, a certificate or certificates for the number of full shares of
the Common Stock to be issued and such holder shall be deemed to have become a
stockholder of record of Common Stock on the Mandatory Offering Date, unless the
transfer books of this corporation are closed on that date, in which event he,
she or it shall be determined to have become a stockholder of record of Common
Stock on the next succeeding date on which the transfer books are open.

                 (iii)  In the event that a holder of Series A Stock, Series B
Stock or Series C Stock converts any Series A Stock, Series B Stock or Series C
Stock into Common Stock pursuant to subsection 4.2.4(a) hereof within ninety
(90) days prior to the date of closing of a Mandatory Offering, such holder
shall be deemed to have converted such shares pursuant to this subsection
4.2.4(l).

     4.2.5  Voting Rights.

            (a)  Voting In General. Subject to any restrictions set forth herein
                 -----------------
or as otherwise required by applicable law, the holder of each share of Series A
Stock, Series B Stock and Series C Stock shall have the right to one vote for
each share of Common Stock into which each such share of Series A Stock, Series
B Stock and Series C Stock could then be converted, and with respect to such
vote, such holder shall have full voting rights and powers equal to the voting
rights and powers of the holders of Common Stock, and shall be entitled,
notwithstanding any provision hereof, to notice of any stockholders' meeting in
accordance with the bylaws of this corporation, and shall be entitled to vote,
together with holders of Common Stock, as a single class on an as-converted
basis and not as separate series, with respect to any question upon which
holders of Common Stock have the right to vote.

                                       15
<PAGE>

         (b) Voting Limitations. The foregoing notwithstanding, a holder of
             ------------------
Common Stock, Series A Stock, Series B Stock or Series C Stock shall not, at any
time, be entitled to vote any shares of this corporation held by it to the
extent that such voting would contravene the provisions of Regulation Y of the
Board of Governors of the Federal Reserve System (12 C.F.R. Part 225), or any
successor to such regulation, or any other law, regulation, rule or other
requirement of any governmental authority as from time to time in effect (the
"Legal Limitations"). The number of shares held by a holder which are rendered
non-voting under the preceding sentence may vary depending upon the
circumstances to which the Legal Limitations are being applied, and the number
of other shares entitled to vote in such circumstance. In the event that only a
portion of a holder's holdings of Common Stock, Series A Stock, Series B Stock
or Series C Stock must be rendered non-voting in order to achieve compliance
with the Legal Limitations, then the holder's holdings of Series C Stock, then
Series B Stock, then Series A Stock, and then Common Stock shall be rendered
non-voting, in that order, until compliance with the Legal Limitations is
achieved. Shares of Series A Stock, Series B Stock, Series C Stock and Common
Stock which are not rendered non-voting under this subsection 4.2.5(b) are
referred to in certain sections and subsections herein as "Series A Voting
Stock," "Series B Voting Stock," "Series C Voting Stock" and "Voting Common
Stock," respectively. This corporation shall be entitled to rely, without
independent verification, upon the representation of any holder that it is
entitled under applicable law to vote the shares held by it, and in no event
shall the corporation be liable to any such holder or any third party arising
from any such vote whether or not permitted by applicable law. A holder of any
shares of Common Stock, Series A Stock, Series B Stock or Series C Stock which
are rendered non-voting in order to comply with the Legal Limitations may not
sell such shares (other than to a purchaser taking such shares subject to the
Legal Limitations) unless:

             (i)   such sale will take place in a dispersed public distribution
in which no purchaser or group of related purchasers acquires shares
representing more than two percent of a class of voting shares of this
corporation;

             (ii)  such sale is to this corporation; or

             (iii) this corporation is notified of such holder's intent to sell
such shares and such sale is to one or more purchasers acceptable to it.

         (c) Fractional Shares. Fractional votes shall not be permitted and any
             -----------------
fractional voting rights available on an as-converted basis (after aggregating
all shares into which shares of Convertible Preferred Stock held by each holder
could be converted) shall be rounded to the nearest whole number (with one-half
being rounded upward).


  4.2.6  Protective Provisions.

other equity security, including any other security convertible into or
exercisable for any equity security, having a preference over or being on a

respect to rights of redemption, liquidation preference, voting or dividends;

substantially all of its property or business or merge into or consolidate with

                   (iii) declare or pay any dividends on its Common Stock or
redeem, purchase or otherwise acquire (or pay into or set aside for a sinking
fund for such purpose) any share or shares of Series A Stock, Series B Stock,
Series C Stock or Common Stock; provided, however, that this restriction shall
not apply to the repurchase of shares of Common stock from employees, officers,

law) of the holders of at least fifty-one percent (51%) of the then outstanding
shares of Series A Voting Stock, Series B Voting Stock and Series C Voting
Stock, voting together as a single class on an as-converted basis and not as
separate series:

                   (i)   make any loans or advances to its employees or any
members of their immediate families, other than travel advances and other
advances made in the ordinary course of business or loans to employees made
pursuant to promissory notes issued for the purchase of shares under a stock
option plan or restricted stock plan approved by the Board of Directors of this
corporation;

                   (ii)  guarantee any indebtedness or obligation of any other
party other than in the ordinary course of business;

                                       17
<PAGE>

                        (iii)  create or suffer to be imposed any lien,
mortgage, security interest or other charge on or against all or substantially
all of the properties or assets of this corporation or any subsidiary; or

                        (iv)   acquire, or permit any subsidiary to acquire, any
stock or other securities of any corporation, partnership or entity unless
immediately following such acquisition such corporation, partnership or entity
would be wholly owned by this corporation or a subsidiary of this corporation.

                   (c)  In addition, this corporation shall not take any of the
following actions which would have the following effects on any of the Series A
Stock, Series B Stock or the Series C Stock (the series so affected being
referred to as the "Subject Series") without first obtaining the approval (by
vote or written consent, as provided by law) of the holders of at least fifty-
one percent (51%) of the then outstanding shares of the Subject Series voting as
a separate class:

                        (i)    alter or change the rights, preferences or
privileges of the shares of the Subject Series so as to affect such shares
adversely; or

                        (ii)   increase or decrease (other than by redemption or
conversion) the total number of authorized shares of the Subject Series.

A Stock Series B Stock or Series C Stock shall be converted pursuant to Section
4.2.4 here of, the shares so converted shall be canceled and shall not be
issuable by this corporation. The Amended and Restated Articles of Incorporation
of this corporation shall be appropriately amended to effect the corresponding
reduction i n this corporation's authorized capital stock.

all classes of stock at the time outstanding having prior rights as to

legally available therefor, such dividends as may be declared from time to time
by the Board of Directors.

          shall give its comments or signify its concurrence to the program
          within one (1) week from the date of its submission by ACL. The
          Acceptance Test Program shall not be implemented by ACL without the
          prior written approval of AZCOM.

     8.2  System Acceptance

          (a)  A System shall be considered complete and ready for System
               Acceptance Test when all the items and components of the
               Equipment installed by ACL are in ACL's judgment, in working
               order.

          (b)  ACL shall inform AZCOM in writing of the completion and readiness
               for System acceptance testing of a System at least two (2) weeks
               in advance of the scheduled testing.

          (c)  The System Acceptance Test shall be conducted by AZCOM under the
               supervision of ACL within a period of seven (7) calendar days for
               each System. ACL shall immediately correct any defect for which
               it may be responsible. Upon successful System Acceptance Test, a

               either Party or no longer needed.

     9.5  The obligations of confidentiality and restricted use are not
          applicable to those portions of the Information that, free from any
          obligation to maintain confidential, were previously known to, or that
          fall into public knowledge without the fault of either Party, or which
          the Parties have agreed in writing need not be kept confidential.


10   LIQUIDATED DAMAGES
     ------------------

     10.1 AZCOM shall have the right to claim liquidated damages from ACL in
          case ACL fails to meet the scheduled date of System Acceptance of a
          System.

     10.2 In case of failure to meet the scheduled date of System Acceptance of
          a System, ACL shall pay AZCOM in United States Dollars, liquidated
          damages in an amount equivalent to 0.10% of the Price for each day of
          delay, Sundays and Holidays included.

     10.3 Where the right to claim liquidated damages exists, the liquidated
          damages payable shall not exceed eight percent (8%) of the price of
          the affected System. In addition, ACL must replace the affected System
          with a part of an equal or greater functionality

     10.4 In consideration of the aggressive schedule of the Project
          Implementation as shown in Annex B, ACL shall be allowed extra time to
          meet the schedule date of completion as follows:

          .  For the sites to be completed in November       : 60 days
          .  For the sites to be completed in December       : 60 days
          .  For the sites to be completed in January        : 30 days
          .  For the sites to be completed in February       : 15 days


          The above means that liquidated damages can only be claimed by AZCOM
          against ACL after the above extension time has likewise been exceeded.

     10.5 The claim of AZCOM for liquidated damages against ACL shall not
          prejudice the exercise of AZCOM of its other right and privileges
          under the contract.

     10.6 Any deferment on the part of AZCOM to remit the downpayment within ten
          (10) days of Contract signing shall allow ACL an extension equivalent
          to the number of days AZCOM has delayed in the remittance of the
          downpayment from the said ten (10) day period.

          only a portion of the Project and that portion is not critical to the
          accomplishment of the Project as a whole, the affected Party shall
          continue to perform its obligations on the portion not affected by the
          event of force majeure.

     12.4 The Party invoking an event of force majeure must immediately notify
          in writing the other Party and specify which of its obligations it is
          prevented from complying with by the event of force majeure, and give
          an estimate of the period during which it is likely that it shall be
          prevented from complying with the said obligations. After the
          occurrence of the event of force majeure is proven, the Schedule and
          the performance bond may, after discussions in good faith, be amended
          by Contract of the Parties.

     12.5 The amendment of the Schedule pursuant to Section 12.4 shall not give
          ACL the right to seek or demand an adjustment or modification of the
          Price.


13   CHANGES
     -------

     13.1 Any request by AZCOM for a change in the Work or any part thereof
          shall be subject to the conformity of ACL.  Such request shall be
          subject to later written confirmation by AZCOM.  The additional cost
          and expenses which may arise on account of such changes, if any, shall
          be borne by AZCOM, and the date of completion of the Work may be
          extended by agreement of the parties.

     13.2 ACL may, with the consent of AZCOM, make minor adjustments in the Work
          as, in its sole discretion, may appear necessary for the proper
          accomplishment of its obligations under this Contract. The said
          adjustments shall be subject to the following conditions: (a) the
          general configuration, general characteristics and quality of the Work
          are maintained;

                                       17
<PAGE>

          (b) the Schedule is not changed or modified; (c) any additional costs
          or expenses which may arise as a consequence of such adjustments shall
          be for the account of ACL; and (d) such adjustments shall be reported
          in writing to AZCOM.

16   SEVERABILITY
     ------------

     If any part, term or provision of this Contract shall become invalid or
     unenforceable, the validity or enforceability of the remaining portions or
     provisions shall not be affected, and the rights and obligations of the
     parties shall be construed as if this Contract did not contain the
     particular invalid or unenforceable part, term or provision.


17   SUCCESSION AND ASSIGNMENT
     -------------------------

     17.1 This Contract shall be binding upon the successors and assigns of the
          Parties and shall not, except as otherwise provided in Section 18.2
          hereof, be assigned in whole or in part by a Party without the prior
          written consent of the other party, and which consent shall not be
          unreasonably withheld.

     17.2 ACL may assign or sub-contract to its subsidiary or associated company
          in the Philippines or any other local entity its rights and
          obligations which ACL decides may be more appropriately performed by
          its subsidiary or associated company in the Philippines or other local
          entity. Before any such assignment or sub-contracting is entered into
          by ACL, it shall seek the comments of AZCOM on such intended course of
          action. However, AZCOM's comments shall not relieve or diminish ACL's
          obligations and responsibilities under this Contract. ACL shall
          continue to be responsible for the workmanship and quality of the work
          of the assignee or sub-contractee, including all acts of default or
          negligence of such

                                       18
<PAGE>

          assignee or sub-contractee, its employees or personnel, as if they
          were the acts of default or negligence of ACL. There is no employer-
          employee relationship between the employees of ACL and AZCOM and vice-
          versa.


18   TERMINATION
     -----------

     18.1 In case of default on the part of ACL:

          18.1.1  If ACL fails to comply with any of the terms and conditions of
                  this Contract after proper written notice by AZCOM, AZCOM
                  shall have the right to terminate this Contract thirty (30)
                  days after a notice of termination has been served on ACL.

          18.1.2  In the event of such termination, AZCOM shall be entitled to
                  retain and apply the balance, which may otherwise be due to
                  ACL under this Contract to pay for the cost to complete the
                  Project. If the said balance is not sufficient to cover the
                  cost of the inoperative or non-functional Equipment or System,
                  the additional cost needed to make the Equipment operative or
                  functional shall be paid by ACL to AZCOM

     18.2 In case of default on the part of AZCOM:

          18.2.1  If AZCOM fails to comply with any of the terms and conditions
                  of this Contract after proper written notice by ACL, ACL shall
                  have the right to terminate this Contract thirty (30) days
                  after a notice of termination has been served on AZCOM.

          18.2.2  In case of such termination, AZCOM shall pay ACL the value of
                  the delivered Equipment and release the performance bond
                  submitted by ACL.


19   ARBITRATION
     -----------

     19.1 In the event of any dispute or difference of opinion arising out of or
          relating to this Contract or breach thereof, the parties shall exert
          their best efforts to settle such dispute or difference amicably.

     19.2 If such dispute or difference is not amicably settled within sixty
          (60) calendar days from its occurrence, the matter shall be settled
          through arbitration by a panel of three (3) arbitrators, one to be
          named by each Party and the third arbitrator shall be chosen by the
          two earlier designated arbitrators. In case they fail to select a
          third arbitrator within fifteen (15) calendar days from the date they
          commenced the discussion of the said selection, the third arbitrator
          shall be appointed by the chairpersons of the National Bar
          Associations of the countries of the Parties.  No one shall be
          nominated or act as an arbitrator who is in any way financially
          interested in this Contract or in the business affairs of any of the
          parties.

     19.3 If any Party is dissatisfied with the decision of the arbitrators, the
          Party concerned shall, within ten (10) calendar days from receipt of
          the decision, notify the arbitrators that it

                                       19
<PAGE>

          disputes the same and the matter shall thereupon be settled under the
          Rules of Conciliation and Arbitration of the International Chamber of
          Commerce. The arbitration proceedings shall be conducted in Geneva,
          Switzerland in the English Language. The resulting award shall be
          final and binding on the parties.

                following:

                9.1.6.1. In the event that the results of System Acceptance
                         Tests carried out are not in accordance with the
                         requirements of the Contract, action shall be taken by
                         ACL to locate and isolate the faults.

                9.1.6.2. Any faults located by ACL or notified to ACL by AZCOM
                         shall be rectified promptly by ACL.

                9.1.6.3. Each corrective action shall be performed by ACL and
                         witnessed by AZCOM. A detailed written report
                         containing particulars relating to the faults together
                         with the results of the re-testing shall be submitted
                         to AZCOM immediately after the corrective actions.

                9.1.6.4. ACL shall recommend the Equipment for re-testing only
                         when all faults have been corrected to meet the
                         requirement of the Contract. AZCOM may also perform
                         additional tests it deems necessary. Such additional
                         test procedures shall be agreed upon by both parties.

                9.1.6.5. The rectification of any particulars referred to in
                         this clause shall be carried out by ACL at its own
                         expense and effected promptly upon receipt of notice
                         thereof.

                9.1.6.6. If ACL fails to rectify any such particulars within a
                         reasonable time, AZCOM may elect to have any or all of
                         such particulars rectified through other means. In
                         which event ACL shall compensate AZCOM, within the
                         limits of ACL's liability under the Contract, for all
                         losses, damages, costs, charges, and expenses which
                         AZCOM may sustain by reason of ACL's failure to effect
                         the necessary corrective measures on the particulars
                         referred to.

        9.1.7.  Each System will be initially accepted after ACL has
                demonstrated to AZCOM that all the requirements of the
                Specifications have been complied with, and provided that the
                result shows that:

                a. the System is functioning properly according to the technical
                   specifications; and

                b. the requirements of the Contract have been met.

                In which event, ACL will be granted by AZCOM a certificate of
                System Acceptance five (5) days from the date of System
                Acceptance. The date of the certificate shall be the completion
                date of the stability test.

        9.1.8.  In the event that AZCOM does not grant a certificate of System
                Acceptance but nevertheless AZCOM and ACL mutually agree in
                writing that the System can be put in commercial service, ACL
                shall issue a waiver on their rights for the
<PAGE>
                issuance of System Acceptance certificate up to a certain period
                of time. Such shall not relieve ACL of his responsibility under
                this Contract and ACL shall continue to be responsible for any
                damage attributable to any part of the System which requires
                corrective action.

        9.1.9.  Items requiring corrective actions and items not provided shall
                be jointly identified by AZCOM and ACL. When the outstanding
                corrective action has been taken and the outstanding items
                delivered and approved by AZCOM in writing, a certificate of
                System Acceptance will be granted.

        9.1.10. After the execution of the System Acceptance Test protocol, the
                representative from AZCOM shall indicate the outcome of each
                test. Providing there are no major failures, the representative
                of AZCOM shall sign and date the test protocol, indicating that
                the System is acceptable.

9.2.    Performance Monitoring

        During the Warranty Period the Network shall be, at AZCOM's discretion,
        tested to ensure that the System performance is in line with the System
        specifications.

        These tests shall be as follows:

        - System Functionality Tests
        - Long Term BER Tests
        - Output Power Measurements on the Base Station

        Before any test is conducted, AZCOM shall notify ACL two weeks in
        advance that a test is to be conducted. ACL shall have the option of
        being present at any test. If a test is conducted whilst ACL is not
        present and the results are a failure, AZCOM shall notify ACL so that
        the test can be repeated after an investigation by ACL. If the test
        fails again ACL shall be given 30 days to apply corrective action. If
        after 30 days no corrective action has been taken or a subsequent test
        again fails, the System under test shall be deemed to have failed
        Performance Monitoring and the Warranty Period shall be extended.

        Once a system has failed Performance Monitoring ACL shall be required to
        take corrective action, including the complete replacement of the System
        in question.

        The System Functionality tests as defined by AZCOM may include, but are
        not limited to the following:

        - System Installation and Service Provisioning
        - System Connectivity: 64kbit/s and 128kbit/s Leased Line Data
          Services
        - Network Management System functionality test

        The Long Term BER Test shall be:
        - 168 hour BER. A Pass shall be when the average BER is better than
        10/-7/.

        The Output Power Test shall be:
        - CT Output Power is within 1.5dB of commissioned level.

                test.

        9.3.3.  This test shall be conducted once and shall be considered as
                final. After passing the acceptance test successfully,
                acceptance certificate for Spares and tools and test equipment
                shall be issued within two (2) weeks therefrom. If AZCOM does
                not issue the said certificate within two (2) weeks for reasons
                not attributable to the fault of ACL, the acceptance certificate
                shall be deemed to have been issued by AZCOM.

        9.3.4.  Warranty of Spares, tools and test equipment shall be for
                eighteen (18) months from the date of Acceptance.

9.4.    Subscriber Terminal Acceptance Test

        Upon the delivery of the Subscriber Terminals to ACL's warehouse in the
        Philippines, an acceptance test shall be performed. After a successful
        ST Acceptance Test and subsequent issuance of an Acceptance Test
        Certificate by AZCOM the Warranty Period on the subscriber terminals
        shall start.

        The Subscriber Terminal Acceptance Test shall be in two parts. The
        second test shall only be undertaken if the first test fails.

        subscriber terminals within a delivery batch. These terminals shall be
        tested for normal leased line data operation, and be given a 60-minute
        BER test conducted over the air. The BER results shall be better than
        10 /-7/.

        If during this first test more than 20% of the terminals fail, the
        second test shall be performed. If less than 20% of the terminals fail
        the whole batch of Subscriber Terminals shall be accepted and a
        successful acceptance test certificate issued.

        The second test shall be a complete test of all the subscriber
        terminals. This test shall be for normal leased line data operation, and
        include a 60-minute BER test conducted over the air. The BER results
        shall be better than 10 /-7/. Only Subscriber Terminals that pass
        this test shall be accepted by AZCOM.

      and on other changes of The Purchaser's Scope of Supply resulting from the
          change in question as well as on any other terms and conditions that
          according to the Contractor shall govern the change. The information
          on prices shall be split on the various items that The Purchaser
          reasonably requires and be accompanied by all necessary drawings and
          specifications including a description of the consequences for the WLL
          System, the environments, the reliability, the maintainability, the
          training of The Purchaser's staff, the Contractor's Scope of Supply
          and The Purchaser's Share of Responsibility etc. sufficiently detailed
          so as to permit The Purchaser to judge on the reasonableness of the
          prices and other terms and conditions.

      If the change has been proposed by The Purchaser the offer shall be
          submitted by the Contractor as soon as practicable, however, in no
          case later than thirty (30) days after receipt of The Purchaser's
          proposal. The Contractor shall be bound by any offer referred to
          herein for such a period of time as is required to enable The
          Purchaser to evaluate and make decision on the basis of the offer.

      Any change according to Subclauses 6.2, 6.3 and 6.6 above has to be agreed
          by The Purchaser in' the form of a written numbered change order or
          supplementary order ("Supplementary Agreement"). The Contractor shall
          not commence any work relating to such a change until The Purchaser
          has authorised the same and all the related terms and conditions.
          However, if The Purchaser so requests in writing, the Contractor shall
          be obliged to commence and carry out minor or urgent changes,
          notwithstanding that all of the terms and conditions have not at that
          time been agreed to by The Purchaser.

6.7   Variations in Prices
- -------------------------

      6.7.1 Increase or decrease in Prices
      ------------------------------------

      In the event that a change referred to in Clause 6 would result in

      (i)  a material increase of the Contractor's costs for the Contractor's
           performance under this Contract or

      (ii) a material decrease of the Contractor's costs for the Contractor's
           performance under this Contract

      then the parties shall mutually in writing agree upon, in good faith, such
      price increase or decrease as the case may be.

      In the ascertainment and determination of such an increase or decrease,
      rates and prices specified in this Contract shall as far as possible serve
      as a guide. Where this is not possible, the increase or decrease shall be
      an amount that is reasonable in view of all the circumstances.

6.7.2 Reimbursements to The Purchaser for increased costs
- ---------------------------------------------------------

      6.7.2.1 It is expressly agreed that The Purchaser shall in no event bear
              any increase of Contract Prices resulting from changes required in
              order to make the WLL System meet the requirements set out in this
              Contract.

      6.7.2.2 Any costs or expenses incurred by The Purchaser due to such a
              change shall be reimbursed by the Contractor on demand and may be
              set off by The Purchaser against any payment The Purchaser shall
              make to the Contractor under this Contract.

      6.7.2.3 In the event that any change would require a change of The
              Purchaser's Share of Responsibility or of any other equipment
              belonging to The Purchaser, and the Contractor has failed to
              inform The Purchaser of this fact prior to the conclusion of the
              Supplementary Agreement referred to in Subclause 6.6 above, the
              Contractor shall reimburse The Purchaser for all such increase of
              costs that The Purchaser will incur due to such a change and the
              provisions of set-off in Subclause 6.7.2.2 above shall apply.

      Clause 7 - Project Group, Progress Report, Time Schedule and Delays
      -------------------------------------------------------------------

7.1  Project Group
- ------------------

     For the supervision of the parties' performance under this Contract, the
     Contractor and The Purchaser shall on The Purchaser's request form a joint
     project group consisting of representatives from each party ("Project
     Group") which shall decide when and where to meet. Each party shall bear
     all costs for its own representatives. Minutes of meetings shall be kept
     and signed by one representative of each party authorized to this effect.
     When considered necessary representatives of subcontractors and experts of
     the parties shall attend the meetings. It is incumbent upon the Contractor
     to see to it that representatives of the Contractor's subcontractors will
     attend, if so required. The costs for such experts shall be borne by the
     party in question. The costs for representatives of the subcontractors of a
     party shall be borne by the party in question or subcontractor, as they may
     have agreed separately.

     At the meetings the Project Group shall discuss the progress of the
     Contractor's Scope of Supply and The Purchaser's Share of Responsibility
     and review the operation and maintenance facilities of the WLL System.

     The Project Group shall supervise the test procedures for Acceptance Tests
     set out in Annex 17.

     The Project Group is authorized to make decisions within the technical
     scope of the Contract . A technical change or correction which entails
     increased costs or extension of the delivery time shall promptly, but
     latest at the next meeting be notified in writing by the Contractor. If
     such notice is not made, the Contractor has no right to demand compensation
     for such increased costs or to demand acceptance by The Purchaser of
     prolongation of the delivery time.

     A decision binding on the parties shall be deemed to have been made only if
     all the representatives of both parties agree and the decision is contained
     in duly signed minutes. The Project Group shall, however, not be authorized
     to make decisions that will affect Contract Price(s) or the Contractual
     Date of Delivery or otherwise decisions resulting in modifications of the
     Contract. In the event that any of the representatives deem a question to
     fall outside the authority or competence of the Project Group the question
     shall be referred for resolution to the Engineering Vice Presidents or
     their equivalents of each party.

     A detailed description of the Project Organisation, including names of the
     persons participating and their experiences in the field is set out in
     Annex 27.

7.2  Progress Report
- --------------------

     The Contractor shall every week submit to The Purchaser a Progress Report
     in three copies up until System Acceptance is achieved. The Progress Report
     shall contain, as a minimum, a report of all activities related to the
     Contract that have taken place since the last report, as well as
     information regarding future activities and the progress of the
     Contractor's Scope of Supply. After System Acceptance progress reports
     shall be issued at a frequency mutually agreed.


     The Progress Report shall furthermore contain a complete review of the
          status of accomplishments, developments and implementation of the
          Contractor's Scope of Supply obligations against the Time Schedule.

7.3. Time Schedule

     As an integral part of this Contract is attached as Annex 18 a Time
     Schedule indicating crucial milestone dates. The Contractor and The
     Purchaser undertake to fulfil their undertakings under this Contract in
     accordance with the Time Schedule. Time is of the essence of this Contract.

7.4  Delays
- -----------

     Without prejudice to the provisions of Clause 17, each party to this
     Contract shall promptly notify the other party in writing where the
     notifying party has a reasonable belief that circumstances exist or are
     likely to occur that would be reasonably expected to prevent the Contractor
     (or any of its subcontractors or suppliers) or The Purchaser (or any of its
     assignees) from fulfilling its obligations under this Contract according to
     the Time Schedule.

     In a case where any party, at any time, reasonably believes that any other
     party is unable to fulfil its obligations on the respective date set out in
     the Time Schedule, the parties shall meet to determine what action is
     required. Any notification and/or action that might be determined as a
     consequence hereof shall be without prejudice to any right or remedy the
     parties may have under this Contract.

                             Clause 8 - Inspection
                             ---------------------

8.1  General
- ------------

     At such times and in such manner as The Purchaser shall deem appropriate
          for the purpose of inspecting or testing the contractual work in
          progress and activities under this Contract, including the
          Contractor's own tests and results thereof, representatives of The
          Purchaser shall be given notices of the testing and shall have access
          to the Contractor's and its subcontractor's works as well as other
          places where activities under this Contract are in preparation or
          progress. The Purchaser shall have full access to and on request be
          provided with all test records relating to the Contractor's Scope of
          Supply. Any inspection or test carried out by The Purchaser or its
          representatives shall not unduly delay the Contractor.

     The Purchaser shall at all reasonable times have access to the Contractor's
          Scope of Supply, and the Contractor shall provide appropriate
          facilities for such access and for the purpose of inspection and
          testing. The Purchaser shall also have full access to all relevant
          plants, offices and Contractor's Scope of Supply sites of the
          Contractor and any of its Subcontractors to enable The Purchaser to
          inspect the Contractor's Scope of Supply and monitor progress.

     The Contractor shall permit The Purchaser or its designated representatives
          to carry out the following inspection activities at any time: (i) to
          audit the Contractor's quality assurance system and its application to
          the Contractor's Scope of Supply including, without limitation, to the
          manufacture, development, and/or provision of raw materials and
          components; and (ii) to inspect all parts of the Contractor's Scope of
          Supply to the extent reasonably practicable to ensure that their
          quality meets the requirements of the Contract.

     The factory inspection or audit of parts of the System in accordance with
          this Clause shall not in any way prejudice any right or remedy which
          The Purchaser may have against the Contractor, or relieve the
          Contractor of any of its liabilities, and in particular it is without
          prejudice to the Contractor's obligations relating to the performance
          of the System under Clause 4.

     Any approval given by or on behalf of The Purchaser in respect of any
          aspect of the Contractor's Scope of Supply carried out or proposed by
          the Contractor, or in respect of any part of the System, shall not
          relieve the Contractor of any obligations under the Contract.

     The Purchaser or its representatives may request that the Contractor
          performs such reasonable tests and repeated tests (in addition to and
          apart from such tests as are referred to in Clause 9) as The Purchaser
          (or its representatives) will consider necessary to be assured that
          the result of the activities will comply with the requirements of this
          Contract. The Contractor shall, without extra costs to The Purchaser,
          provide with all labour, facilities, test equipment and other things
          and services necessary for this purpose.

     In the event that Software or Equipment is in the course of the inspection
          found to be defective or otherwise not in conformity with the
          Specifications, the Contractor shall within shortest possible time
          take all necessary action to repair all faults, defects or non-
          conformance.

8.2  Subcontractors
- -------------------

     The Contractor shall ensure that the provisions of this Clause 8 also apply
     to all subcontracts or orders made or placed by the Contractor with any one
     of its subcontractors and that the provisions of this Clause 8 are held
     good by the said subcontractors.

          by The Purchaser in' the form of a written numbered change order or
          supplementary order ("Supplementary Agreement"). The Contractor shall

          be obliged to commence and carry out minor or urgent changes,
          notwithstanding that all of the terms and conditions have not at that
          time been agreed to by The Purchaser.

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

     6.7.1  Increase or decrease in Prices

           performance under this Contract or

     (iv)  a material decrease of the Contractor's costs for the Contractor's
           performance under this Contract

        then the parties shall mutually in writing agree upon, in good faith,
        such price increase or decrease as the case may be.

        In the ascertainment and determination of such an increase or decrease,
        rates and prices specified in this Contract shall as far as possible
        serve as a guide. Where this is not possible, the increase or decrease
        shall be an amount that is reasonable in view of all the circumstances.

6.7.2   Reimbursements to The Purchaser for increased costs
- -----------------------------------------------------------

        6.7.2.1  It is expressly agreed that The Purchaser shall in no event

                 set out in this Contract.

        6.7.2.2  Any costs or expenses incurred by The Purchaser due to such a
                 change shall be reimbursed by the Contractor on demand and may
                 be set off by The Purchaser against any payment The Purchaser
                 shall make to the Contractor under this Contract.

        6.7.2.3  In the event that any change would require a change of The
                 Purchaser's Share of Responsibility or of any other equipment
                 belonging to The Purchaser, and the Contractor has failed to
                 inform The Purchaser of this fact prior to the conclusion of
                 the Supplementary Agreement referred to in Subclause 6.6 above,
                 the Contractor shall reimburse The Purchaser for all such
                 increase of costs that The Purchaser will incur due to such a
                 change and the provisions of set-off in Subclause 6.7.2.2 above

      Clause 7 - Project Group, Progress Report, Time Schedule and Delays
      -------------------------------------------------------------------

7.1  Project Group
- ------------------

     For the supervision of the parties' performance under this Contract, the
     Contractor and The Purchaser shall on The Purchaser's request form a joint
     project group consisting of representatives from each party ("Project
     Group") which shall decide when and where to meet. Each party shall bear
     all costs for its own representatives. Minutes of meetings shall be kept
     and signed by one representative of each party authorized to this effect.
     When considered necessary representatives of subcontractors and experts of
     the parties shall attend the meetings. It is incumbent upon the Contractor
     to see to it that representatives of the Contractor's subcontractors will
     attend, if so required. The costs for such experts shall be borne by the
     party in question. The costs for representatives of the subcontractors of a
     party shall be borne by the party in question or subcontractor, as they may
     have agreed separately.

     At the meetings the Project Group shall discuss the progress of the
     Contractor's Scope of Supply and The Purchaser's Share of Responsibility
     and review the operation and maintenance facilities of the WLL System.

     The Project Group shall supervise the test procedures for Acceptance Tests
     set out in Annex 17.

     The Project Group is authorized to make decisions within the technical
     scope of the Contract. A technical change or correction which entails
     increased costs or extension of the delivery time shall promptly, but
     latest at the next meeting be notified in writing by the Contractor. If
     such notice is not made, the Contractor has no right to demand compensation
     for such increased costs or to demand acceptance by The Purchaser of
     prolongation of the delivery time.

     A decision binding on the parties shall be deemed to have been made only if
     all the representatives of both parties agree and the decision is contained
     in duly signed minutes. The Project Group shall, however, not be authorized
     to make decisions that will affect Contract Price(s) or the Contractual
     Date of Delivery or otherwise decisions resulting in modifications of the
     Contract. In the event that any of the representatives deem a question to
     fall outside the authority or competence of the Project Group the question
     shall be referred for resolution to the Engineering Vice Presidents or
     their equivalents of each party.

     A detailed description of the Project Organisation, including names of the
     persons participating and their experiences in the field is set out in
     Annex 27.

7.2  Progress Report
- --------------------

     The Contractor shall every week submit to The Purchaser a Progress Report
     in three copies up until System Acceptance is achieved. The Progress Report
     shall contain, as a minimum, a report of all activities related to the
     Contract that have taken place since the last report, as well as
     information regarding future activities and the progress of the
     Contractor's Scope of Supply. After System Acceptance progress reports
     shall be issued at a frequency mutually agreed.

                                      13

     The Progress Report shall furthermore contain a complete review of the
          status of accomplishments, developments and implementation of the
          Contractor's Scope of Supply obligations against the Time Schedule.

7.3. Time Schedule
- ------------------

     As an integral part of this Contract is attached as Annex 18 a Time
     Schedule indicating crucial milestone dates. The Contractor and The
     Purchaser undertake to fulfil their undertakings under this Contract in
     accordance with the Time Schedule. Time is of the essence of this Contract.

7.4  Delays
- -----------

     Without prejudice to the provisions of Clause 17, each party to this
     Contract shall promptly notify the other party in writing where the
     notifying party has a reasonable belief that circumstances exist or are
     likely to occur that would be reasonably expected to prevent the Contractor
     (or any of its subcontractors or suppliers) or The Purchaser (or any of its
     assignees) from fulfilling its obligations under this Contract according to
     the Time Schedule.

     In a case where any party, at any time, reasonably believes that any other
     party is unable to fulfil its obligations on the respective date set out in
     the Time Schedule, the parties shall meet to determine what action is
     required. Any notification and/or action that might be determined as a
     consequence hereof shall be without prejudice to any right or remedy the
     parties may have under this Contract.

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

8.1  General
- ------------

     At such times and in such manner as The Purchaser shall deem appropriate
          for the purpose of inspecting or testing the contractual work in
          progress and activities under this Contract, including the
          Contractor's own tests and results thereof, representatives of The
          Purchaser shall be given notices of the testing and shall have access
          to the Contractor's and its subcontractor's works as well as other
          places where activities under this Contract are in preparation or
          progress. The Purchaser shall have full access to and on request be
          provided with all test records relating to the Contractor's Scope of
          Supply. Any inspection or test carried out by The Purchaser or its
          representatives shall not unduly delay the Contractor.

     The Purchaser shall at all reasonable times have access to the
          Contractor's Scope of Supply, and the Contractor shall provide
          appropriate facilities for such access and for the purpose of
          inspection and testing. The Purchaser shall also have full access to
          all relevant plants, offices and Contractor's Scope of Supply sites of
          the Contractor and any of its Subcontractors to enable The Purchaser
          to inspect the Contractor's Scope of Supply and monitor progress.

     The Contractor shall permit The Purchaser or its designated representatives
          to carry out the following inspection activities at any time: (i) to
          audit the Contractor's quality assurance system and its application to
          the Contractor's Scope of Supply including, without limitation, to the
          manufacture, development, and/or provision of raw materials and
          components; and (ii) to inspect all parts of the Contractor's Scope of
          Supply to the extent reasonably practicable to ensure that their
          quality meets the requirements of the Contract.

     The factory inspection or audit of parts of the System in accordance with
          this Clause shall not in any way prejudice any right or remedy which
          The Purchaser may have against the Contractor, or relieve the
          Contractor of any of its liabilities, and in particular it is without
          prejudice to the Contractor's obligations relating to the performance
          of the System under Clause 4.

     Any approval given by or on behalf of The Purchaser in respect of any
          aspect of the Contractor's Scope of Supply carried out or proposed by
          the Contractor, or in respect of any part of the System, shall not
          relieve the Contractor of any obligations under the Contract.

     The Purchaser or its representatives may request that the Contractor
          performs such reasonable tests and repeated tests (in addition to and
          apart from such tests as are referred to in Clause 9) as The Purchaser
          (or its representatives) will consider necessary to be assured that
          the result of the activities will comply with the requirements of this
          Contract. The Contractor shall, without extra costs to The Purchaser,
          provide with all labour, facilities, test equipment and other things
          and services necessary for this purpose.

     In the event that Software or Equipment is in the course of the inspection
          found to be defective or otherwise not in conformity with the
          Specifications, the Contractor shall within shortest possible time
          take all necessary action to repair all faults, defects or non-
          conformance.

8.2  Subcontractors

           Clause 9  Acceptance Procedure and Actual Date of Delivery
           ----------------------------------------------------------

9.1  General
- ------------

     The Acceptance Procedure falls into the following main events:
     - Quality assurance
     - Visual Inspection
     - System test (known as Site Acceptance)
     - Acceptance test (known as System Acceptance)
     - TEC tests
     Except to the extent otherwise specifically provided in this Contract the
            Contractor shall be responsible for the performance of the quality
            surveillance, inspections, tests (including repeated tests, if any)
            which are required for the completion of Contractor's Scope of
            Supply and for the demonstration of its compliance with the
            Specifications and other requirements set out in this Contract. For
            the purpose of achieving this object the Contractor shall except to
            the extent otherwise specifically provided in this Contract be
            obliged at its own expense

     (i)    to carry out the said surveillance and perform and supervise the
            tests;
     (ii)   provide with or place at The Purchaser's disposal, as the case may
            be, all equipment, tools, programs (software), labour, supplies, and
            services required for the performance of the said surveillance and
            tests; and
     (iii)  to issue reports, keep and provide records, and issue certificates
            as to the results of the surveillance and tests. The said
            surveillance and all the tests shall be performed at the
            Contractor's risk.

All reasonable direct costs to which The Purchaser may be put by any repetition
of an inspection or a test shall be reimbursed by the Contractor on demand and
may be deducted by The Purchaser from any moneys to be paid by The Purchaser
under this Contract.

9.2  Quality Assurance
- ----------------------

     The Contractor shall be responsible for carrying out a continuous quality
     surveillance in accordance with the quality assurance procedure laid down
     in Annex 15 in order to ensure that the Equipment and the Software in all
              --
     respects will meet all the requirements set out in this Contract.

9.3  System Test (or Site Acceptance Test)
- ------------------------------------------

     The Contractor shall be responsible for carrying out a System test for each
     site. Representatives of The Purchaser shall be present. The object of the
     System test is to establish that each part of the WLL System will fulfil
     all the functional and technical requirements set out in this Contract.

     As soon as possible after completion of the System test, the Contractor
     shall furnish to The Purchaser a report regarding the test. To the extent
     an unsuccessful test so requires, the Contractor shall cure the discovered
     deviation from the requirements and provide for repeated test.

     Prior to the start of any System Acceptance Test the Contractor shall have
     proved that the System tests have been successful and have cured to the
     satisfaction of The Purchaser the deviation from the requirements or any
     other defect or deficiency that

- --------------------------------------------------------------------------------
(C) Suntel Private LTD               Confidential                       1999
<PAGE>

                                      17

     has been observed in the course of the System test. If the Purchaser agrees
     a System Acceptance Test can take place without all System Tests being
     complete.

     To the extent an unsuccessful test so requires, the Contractor shall cure
     the discovered deviation from the requirements and provide for a repeated
     test.

     At the time when the Contractor has successfully completed a Systems Test
     (Site Acceptance Test), the Purchaser shall accept the title and risk for
     that part of the network that has been successfully tested. Alternatively,
     provision of revenue producing traffic for more than one month will
     constitute completion of System Test for a specific site.

9.4  Acceptance Test
- --------------------

     When,

     (i)     the tests and inspections referred to above in this Clause 9 have
             demonstrated that all Equipment and Software delivered by the
             Contractor complies with all relevant requirements, standards and
             Specifications;

     (ii)    such Equipment and Software as shall be installed by Contractor has
             been installed on Premises ready for operation;

     (iii)   relevant training referred to in Clause 11 has been performed;

     (iv)    relevant documentation has been delivered in accordance with Clause
             11,

     and

     (v)     relevant Test Equipment have been delivered in accordance with
             Clause 11, then The Purchaser shall perform an acceptance test
             ("System Acceptance Test"). The purpose of this Acceptance Test is
             to establish whether the Equipment and the Software complies with
             all the relevant requirements and Specifications when operated and
             otherwise handled by The Purchaser personnel duly trained by the
             Contractor utilising the Documentation supplied by the Contractor.
             The detailed test procedure and criteria of a successful Acceptance
             Test shall be agreed upon in accordance with Clause 7.1.

9.5  Actual Date of Delivery
- ----------------------------

     The Acceptance Test shall be deemed to have been successfully performed
     when it has been demonstrated that all relevant requirements of this
     Contract are met or when the Purchaser has carried commercial traffic for a
     period of more than 90 days.

     The Actual date of Delivery is when all defects, deficiencies, or
     deviations from the requirements discovered in connection with the
     Acceptance test, or prior thereto, have been cured to the satisfaction of
     The Purchaser, and a successful Acceptance Test has shown that Contractor's
     Scope of Supply with respect to WLL System meets all the requirements of
     this Contract.

     It is recognised by the parties that even after the Acceptance Test, some
     minor defects and deficiencies that are non-essential for the proper
     operation or

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

                                      18

     maintenance of the WLL System might exist. The parties shall by agreement
     enter these defects or deficiencies into a list of defects which shall also
     include a time schedule for the taking by Contractor of the necessary
     corrective measures. The stipulations of this Contract as regards warranty
     obligations contained in Clause 10 below shall apply to Contractor's duty
     to take such corrective measures.

     If the Purchaser fails to make any or all sites available for Installation
     of the equipment one hundred and twenty days (120) after the contract
     signature, the Purchaser shall by default accept the equipment, for that
     part of the network that cannot be installed, and make all relevant
     payments applicable to Site and System Acceptance. At this time, title and
     risk for the equipment that cannot be installed shall pass from the
     Contractor to the Purchaser.

     If the System Acceptance Test (required before Actual Date of Delivery can
     be achieved) is delayed because of the Purchaser's failure to make sites
     "ready for installation", the System Acceptance Test shall be conducted
     only on those sites that have passed Site Acceptance.

     The Time Schedule and Milestones for the implementation and preparation of
     the Sites by the Purchaser shall be defined in Annex 18.

       Clause 12 - Liquidated Damages in the Event of Delays in Delivery
       -----------------------------------------------------------------

12.1     General
- ----------------

The parties acknowledge that the Contractor's fulfillment of its undertakings
set out in the Time Schedule (Annex 18) is of utmost importance to The
Purchaser. The parties also acknowledge that delays will cause severe damage to
The Purchaser and that such damage may, from a practical point of view, be
difficult to quantify. In the event of delay, the parties agree that The
Purchaser shall receive liquidated damages in accordance with the following
provisions without The Purchaser being obligated to prove that it has suffered
damage or to prove the amount of damage. The Purchaser's right to receive
liquidated damages shall be without prejudice to any other right that it may
have under this Contract or otherwise.

Any liquidated damages to which The Purchaser is entitled shall be paid by the
Contractor upon demand and The Purchaser shall be entitled to wholly or partly
set off liquidated damages against any amount that The Purchaser shall pay to
the Contractor under this Contract.

12.1.1   Liquidated Damages for Delay
- -------------------------------------

         Should the service start date of the System, or any material portion of
         the System be delayed for any reason except for events excepted under
         this Contract, where the delay is fully or substantially attributable
         to the fault of default of the Contractor (including its sub-
         contractors), Contractor shall pay liquidated damages equal to one
         percent (1%) of the value of that part of the network that The
         Purchaser is unable to use for each week or fraction of a week of delay
         beyond Actual Date of Delivery as specified in Annex 18. A grace period
         of two weeks shall be given before the first week of delay is counted.
         Upon the lapse of the second week of delay, however, the full delay
         shall be counted in computing the liquidated damages.

12.2     WLL System, Training, Documentation, Spare Parts and Test Instruments
- ------------------------------------------------------------------------------

         In the event that Contractor does not fulfil any of its undertakings
         with respect to WLL System, training, Documentation, spare parts or
         test instruments on the respective dates set out in the Time Schedule,
         the Contractor shall pay liquidated damages to The Purchaser for each
         whole day of delay amounting to (0.1%) of the respective Contract
         Price.

         Maximum liquidated damages according to these Clauses 12.1.1 and 12.2
         shall in no case exceed ten per cent (10 %) of the Total Contract
         Price.

12.3     Delays Caused by The Purchaser or Force Majeure Events
- ---------------------------------------------------------------

         The Purchaser shall not be entitled to liquidated damages according to
         the above provisions of this Clause 12 to the extent the delay in
         question is caused by failure solely on part of The Purchaser to fulfil
         any part of its Share of Responsibility or by a Force Majeure Event
         defined in Clause 17.

         In the event that The Purchaser delays in carrying out any of its
         undertakings under this Contract the Contractor shall nevertheless be
         obliged to fulfil its obligations within the time agreed on, to the
         extent that the fulfilment of The Purchaser's obligations is not
         necessary to enable the Contractor or its subcontractors and suppliers
         to fulfil their obligations. In the event that it can reasonably be
         assumed

         undertakings under this Contract, The Purchaser shall have the right to

person to patent, copyright, design or any intellectual or industrial property
rights or application therefore, as well as to hold The Purchaser, its officers,
employees, and representatives harmless from and fully indemnify them for any

(i)  procure for The Purchaser the right to continue the use, or
(ii) replace or modify the WLL System, or Documentation, so that it becomes non-
     infringing while staying fully compliant with the Specifications. Any such
     replacement or modification shall, however, be approved of by The Purchaser
     in advance, which approval shall not be unreasonably withheld. The
     Purchaser shall without delay inform the Contractor of any claim that has

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

Should Force Majeure Event occur after the signing of this Contract which
prevents the performance of any obligation of either party on the date or dates
provided for in this Contract, the performance of the obligation may be
postponed for such time, on a day by day basis, as the performance necessarily
has had to be delayed on account thereof, it being understood that such
postponement shall not be deemed a change of the Time Schedule or of any day
defined by reference to the Time Schedule.

The term of Force Majeure Event shall mean events such as war or warlike
hostilities, mobilisation or general military call-up, acts of Government
including refusal issue of required export licenses (but shall exclude failure
to obtain security clearance for own employees), civil war, revolution,
rebellion, insurrection or riots, sabotage and any strike or labour action and
other circumstances of a similar exceptional character and farreaching
influence, provided that any such event is beyond the control of the party, its
subcontractors and suppliers. It is expressly understood that no circumstance
shall be considered Force Majeure Event which the party or the subcontractor or
the supplier invoking the event of Force Majeure reasonably ought to have taken
into account at the date of signing of this Contract.

Immediately upon becoming aware of the commencement of any Force Majeure Event
causing a delay, and immediately upon becoming aware of the termination of such
an event of Force Majeure, the party desiring to invoke it as cause for
postponement shall advise the other party of the said event, failing which its
right to demand an extension of the time of performance shall be definitely
barred. To avail itself of the right to invoke any Force Majeure Event as a
cause for postponement the party shall also as soon as practicable after the
termination of the event submit to the other party reasonable proof of the
nature of such Force Majeure Event and its effect upon the performance
timetable. Each parties shall make all reasonable efforts to reduce to a minimum
and mitigate the effect of any delay occasioned by a Force Majeure Event. The
obligation of Contractor in this respect shall particularly include the
repairing or causing the repair of such damage as may have been done to its or
its subcontractor's manufacturing facilities or to Contractor's Scope of Supply.

The Contractor and its subcontractors shall abide by all applicable laws,

inform the Contractor and, in such event, The Purchaser shall be entitled to
refuse admission to the Premises of any person who is responsible for such

information received or obtained when present on the Premises and to sign
documents to such an effect. The Purchaser shall not be responsible for any
acts, default or unsatisfactory performance, neglect or omissions of the
Contractor that violate the laws, statutes, orders, rules, decrees, or
regulations of any jurisdiction in which the Contractor's Scope of Supply
obligations are carried out.

The Purchaser because of such act, default, unsatisfactory performance or
omission of Contractor, The Purchaser shall notify the Contractor as soon as
possible, and the Contractor shall be entitled to undertake and manage any legal
proceedings involving the Contractor. The Contractor shall upon the request of
The Purchaser assist The Purchaser in defending themselves against such claim
and indemnify and hold The Purchaser harmless against any and all costs,
charges, expenses, compensations and other payments made by The Purchaser in
respect of such third party claim.

necessary information with respect to the Contractor's Scope of Supply and the
Contract including but not limited to the matters such as: (i) fees, pilotage
and any dues payable to port authorities, (ii) conditions affecting labour
including Contractor's Scope of Supply permits, and (iii) rules and regulations
of governments and/or port authorities.

The Contractor shall be deemed to have fully examined and independently verified
all documents and drawings, specifications, schedules, terms and conditions of
the Order, regulations and other information in relation to the Contract and to
have fully understood and satisfied himself as to all information which is
relevant as to the risks whether political or otherwise, contingencies, costs,
and other circumstances which could affect the Contract. The Purchaser, its
servants, and agents shall have no liability in law or equity or in Contract or
in tort or pertinent to any other cause of action with respect to any such
information, risks, contingencies or other circumstances.

     assign a contract, sub-contract, or any significant part of the

     relieved from responsibility under this Contract for such parts of the
     Contractor's Scope of Supply that are sub-contracted, and the Contractor

set out in the Time Schedule (Annex 18) is of utmost importance to The
Purchaser. The parties also acknowledge that delays will cause severe damage to
The Purchaser and that such damage may, from a practical point of view, be
difficult to quantify. In the event of delay, the parties agree that The
Purchaser shall receive liquidated damages in accordance with the following
provisions without The Purchaser being obligated to prove that it has suffered
damage or to prove the amount of damage. The Purchaser's right to receive
liquidated damages shall be without prejudice to any other right that it may
have under this Contract or otherwise.

Contractor upon demand and The Purchaser shall be entitled to wholly or partly
set off liquidated damages against any amount that The Purchaser shall pay to
the Contractor under this Contract.

       Should the service start date of the System, or any material portion of

       the fault of default of the Contractor (including its sub-contractors),
       Contractor shall pay liquidated damages equal to one percent (1%) of the
       value of that part of the network that The Purchaser is unable to use for
       each week or fraction of a week of delay beyond Actual Date of Delivery
       as specified in Annex 18. A grace period of two weeks shall be given
       before the first week of delay is counted. Upon the lapse of the second

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

       The Purchaser shall not be entitled to liquidated damages according to
       the above provisions of this Clause 12 to the extent the delay in
       question is caused by failure solely on part of The Purchaser to fulfil
       any part of its Share of Responsibility or by a Force Majeure Event
       defined in Clause 17.

       In the event that The Purchaser delays in carrying out any of its
       undertakings under this Contract the Contractor shall nevertheless be
       obliged to fulfil its obligations within the time agreed on, to the
       extent that the fulfilment of The Purchaser's obligations is not
       necessary to enable the Contractor or its subcontractors and suppliers to
       fulfil their obligations. In the event that it can reasonably be assumed

against any claim for an infringement or alleged infringement of any
intellectual property right relating to use of the Equipment and Software

employees, and representatives harmless from and fully indemnify them for any

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

Should Force Majeure Event occur after the signing of this Contract which
prevents the performance of any obligation of either party on the date or dates
provided for in this Contract, the performance of the obligation may be
postponed for such time, on a day by day basis, as the performance necessarily
has had to be delayed on account thereof, it being understood that such
postponement shall not be deemed a change of the Time Schedule or of any day
defined by reference to the Time Schedule.

The term of Force Majeure Event shall mean events such as war or warlike
hostilities, mobilisation or general military call-up, acts of Government
including refusal issue of required export licenses (but shall exclude failure
to obtain security clearance for own employees), civil war, revolution,
rebellion, insurrection or riots, sabotage and any strike or labour action and
other circumstances of a similar exceptional character and farreaching
influence, provided that any such event is beyond the control of the party, its
subcontractors and suppliers. It is expressly understood that no circumstance
shall be considered Force Majeure Event which the party or the subcontractor or
the supplier invoking the event of Force Majeure reasonably ought to have taken
into account at the date of signing of this Contract.

Immediately upon becoming aware of the commencement of any Force Majeure Event
causing a delay, and immediately upon becoming aware of the termination of such
an event of Force Majeure, the party desiring to invoke it as cause for
postponement shall advise the other party of the said event, failing which its
right to demand an extension of the time of performance shall be definitely
barred. To avail itself of the right to invoke any Force Majeure Event as a
cause for postponement the party shall also as soon as practicable after the
termination of the event submit to the other party reasonable proof of the
nature of such Force Majeure Event and its effect upon the performance
timetable. Each parties shall make all reasonable efforts to reduce to a minimum
and mitigate the effect of any delay occasioned by a Force Majeure Event. The
obligation of Contractor in this respect shall particularly include the
repairing or causing the repair of such damage as may have been done to its or

2.  EXECUTIVE SUMMARY

This document describes Airspan Communications Corporation (ACC)'s Wireless
Fixed Access(WFA) systems. These systems meet the requirements of network
operators who wish to offer "copper equivalent" services via radio.

Airspan's systems  were created to:

 .   Support a complete range of telecommunication services including telephony,
    Group 3 and Group 4 facsimile, payphone, data modems, high speed leased line
    data, Internet Access and basic rate ISDN.

 .   Be economical to deploy in urban, suburban and rural areas.

 .   Have capacity that can be easily expanded as the customer base grows.

 .   Minimize initial capital outlay.

 .   Operate in a Point-to-Multipoint system configuration.

 .   Conform to the ETSI standards EN 301 055 and 301 124 for CDMA Point-to-
    Multipoint systems in the 1-3GHz and 3-11GHz bands.

Airspan's systems are best described as a "flexible access tool" for network
operators to provide a variety of services to their end-user customers.
Significantly, they are able to provide services that are the same quality and
performance as wireline services, by supporting a transparent connection to the
operator's network.  The combination of voice coding at either 64kbit/s PCM or
32kbit/s ADPCM, Bit Error Rates (BER) of 1 x 10-7 and low delay (typically
{less than}10ms) ensure that advanced telephony services, including G3 facsimile
and high speed data modems (up to 56kbit/s) for Internet applications are fully
supported. They are also the only fixed WLL systems to fully support basic rate
ISDN service in the 2B + D channel format.

Airspan's systems support numerous applications within both existing and new
telecommunications networks, and has been deployed in both developed and
developing country environments. For example:

 .   In developing countries to reduce the waiting list for telephony services,
    in residential, business and payphone applications. This enables rapid
    deployment of a low cost / high value telephony infrastructure that
    typically exceeds the quality and performance of existing copper access
    networks.

 .   In developed countries as a "copper alternative", to modernize the access
    networks, reduce operating costs and thus reduce the cost of universal
    service provision.

 .   In both developed and developing countries to provide a "local loop bypass",
    allowing a new operator to provide wireless based services at a quality
    normally only available with wireline networks. Additionally the system is
    cost effective and quick to deploy compared with traditional copper access
    networks.

 .   In private networks to provide a range of telephony and leased line data
    services supported by transmission rates of N x 64kbit/s (N = 1 to 6).

3.  WIRELESS LOCAL LOOP (WLL) OVERVIEW

"Wireless Local Loop" (WLL) is a loose term used to describe the application of
radio technology in the local access network, as an alternative to traditional
copper pairs between the local exchange and subscribers' premises. However, like
most generic terms, WLL covers a very broad spectrum of solutions. Numerous
architectures exist, each described as WLL, and each significantly different to
the other.

All Wireless Local Loop solutions are designed as an alternative to a copper
access infrastructure, as shown below. This "generalized architecture" is
globally applicable and represents 99% of all wireline access infrastructures
installed around the world today.

                              [GRAPHIC APPEARS HERE]


This copper access architecture consists of three parts, the Feeder network, the
Distribution network and the Drop.

It is generally accepted that five different WLL architectures exist, each is an
alternative to all or some of the copper access network architecture shown
above. The different architectures are shown below:


                              [GRAPHIC APPEARS HERE]
<PAGE>

3.1.  "WIRELESS FIXED ACCESS"

     "Wireless Fixed Access" is the term used to describe products and
     architectures that are direct alternatives to copper-based "Wireline" Drop,
     Distribution and Feeder Networks. These types of systems deliver the same
     Services, Quality and Grade of Service as copper. Generally they are
     optimized to substitute copper-based networks in semi-rural (for example
     Western European Rural) and Suburban environments. This is the architecture
     supported by Airspan's systems.


3.2.  "FIXED CELLULAR"

     "Fixed Cellular" as the name implies is the application of Mobile Cellular
     Radio technology to the local loop. These types of system replace the
     distribution and drop parts of the network, but usually require
     installation of special Base Station sites, as the system may be configured
     to support mobile subscribers as well as wireline replacement. The major
     disadvantage of "Fixed Cellular" is that the equipment was originally
     designed for mobile voice telephony, and not designed to provide the same
     services, quality, or Grade of Service as copper. Fixed Cellular is
     suitable for rural / suburban and urban deployments, and can be planned for
     in-building coverage. It can also provide full mobility if required.


3.3. "WIRELESS DROP"

     "Wireless Drop" is an alternative to copper-based drop segments e.g. the
     last 100 meters. This architecture is typically based on cordless telephony
     technology, such as CT2, DECT or PHS. Because it has a limited range
     (typically {less than}5km) it is suitable for suburban and urban
     deployments. In some deployments it can also provide limited mobility. The
     network cost of this type of solution can be high due to the large number
     of cells and supporting infrastructure required. Airspan's systems can be
     deployed to provide a cost effective "backhaul" for these networks.

3.4. "Microwave Point to Multipoint"

     "Microwave Point to Multipoint" is a very mature technology that was
     developed to provide telephony service in extremely sparsely populated
     areas. These types of systems are designed to provide long distance feeder
     and distribution links are specifically designed for this application, and
     are suitable for very remote, rural telephony. Typically they are low
     capacity systems, and are configured to provide multiple multi-line drops,
     rather than drops for individual customer premises.


3.5.  "MICROWAVE POINT TO POINT"

     The last category is "Microwave Point to Point" and is typically used for
     the direct connection of larger (business) customers to the switching
     network. This
<PAGE>

     type of system is designed for N x 2Mbit/s distribution and is typically
     deployed in urban / suburban areas at 10GHz +.

     Each of these architectures can be deployed separately or in combinations
     in an operator's network to deliver the required services to subscribers.
     Careful assessment is therefore required to determine which technologies
     are most appropriate.

4.  WIRELESS FIXED ACCESS

4.1.  SYSTEM OVERVIEW

     Airspan's Wireless Fixed Access (WFA) systems are digital point to
     multipoint radio access systems providing wireless access for fixed end-
     users to a telecommunication operator's network.

     The systems are specifically designed for Wireless Fixed Access
     applications and are not "fixed" versions of  mobile cellular or cordless
     systems. They deliver telephony, voice-band facsimile/data, higher rate
     digital data and basic rate ISDN. Distances up to 25km can be covered. They
     are therefore an attractive alternative to traditional copper "local loops"
     for the delivery of these services to end-users.

                              [GRAPHIC APPEARS HERE]


                          GENERAL SYSTEM ARCHITECTURE


     The systems use point to multipoint microwave radio links between the
     individual end-user's premises and the network operator's "local point of
     presence" as an alternative to the copper pair "local loop". The "local
     point of presence" would typically be the local exchange premises. If
     greater flexibility or range is required, the Central Terminal (cell site)
     equipment can be remotely located in a suitable building or an
     environmentally protected wayside cabinet, and connected to the local
     exchange via radio, cable or fiber digital transmission links.

     Both Fixed Assigned (FA) and Demand Assigned (DA) access to the air-
     interface between the Central Terminal and Subscriber Terminals is
     supported.

     The range of services supported includes:

 .   Analogue telephony (POTS).

 .   Voice-band Group 3 facsimile and data up to 33.6kbit/s (extending to
    56kbit/s where there are digital interfaces between Airspan and the switch
    network).
<PAGE>

 .   Payphones, including pulse metering.

 .   CLASS services.

 .   64kbit/s and n x 64kbit/s leased line data services.

 .   Basic rate ISDN (2B + D).

    A portfolio of Subscriber Terminals (ST) are available supporting one or
    more lines at each end-user location.


4.2.  CONFORMANCE TO STANDARDS.

     Airspan's WFA system architecture is in accordance with the ETSI standards
     EN 301 055 and 301 124 for Direct Sequence Code Division Multiple Access
     (DS - CDMA) Point-to Multipoint digital radio systems as shown below:


                              [GRAPHIC APPEARS HERE]


     The ETSI standard permits an operator to use systems from different
     vendors. The standard addresses:

 .   Interoperability on Radio interface: Spectrum Masks, Spurious Emissions,
    Receiver Specs, Co and Adjacent Channel Interference Performance are
    defined. Reference is made to relevant ITU-R and CEPT standards.

 .   Host Network Interconnection is covered by references to relevant ETSI V5.x
    standards and TMN standards.

 .   Subscriber Services and Interconnection is covered by reference to relevant
    ITU-T standards.
<PAGE>

4.3.     SYSTEM INTERFACES

         Interfaces between the various elements of Airspan's systems are as
         follows:

4.3.1. THE EXCHANGE INTERFACE

       The interface between the WFA systems and the switch is N x 2Mbit/s
       G703 / G704 (1 per radio carrier typically 4 per CT).

       For the FIXED ASSIGNED system the following signaling protocols are
       supported:

     .  Channel Associated Signaling (CAS). Variants are available to interface
        with switches from Ericsson (AXE), Nortel (DMS-100) and Siemens (EWSD).
        Variants can be made available to interface with other manufacturers
        digital switches that have 2Mbit/s subscriber ports. This protocol also
        supports 2 wire analogue interfaces via channel banks, such as the LS-
        120.

     .  Common Channel Signaling (CCS). UK DASS2 is available to interface with
        GPT (System X) and Ericsson (AXE) switches. DSS1 signaling to support
        Euro-ISDN is available to interface with Alcatel (S12) and Ericsson
        (AXE) switches.
        In addition V5.1 is supported.

     For the DEMAND ASSIGNED system the Access Concentrator (AC) provides the
     primary network interface which is N x 2Mbit/s, as per ITU recommendation
     G.703, short haul 6dB, G.704 and ETSI ETS 300-166.

     All signaling is digital using either Channel Associated Signaling (CAS) or
     Common Channel Signaling (CCS) protocols.  The DA system interfaces to
     digital switching systems that have 2Mbit/s subscriber ports.

     Support for 2 wire VF interfacing is via external channel bank equipment,
     such as the LS-120.

     .   Channel Associated Signaling. Support for timeslot 16 ABCD bit CAS is
         provided. Airspan's management systems allow for flexible configuration
         of the protocol, to interface with switches from various manufacturers.

     .   Common Channel Signaling. V5.1 and V5.2 are supported by the DA system.
         Proprietary protocols such as DASS2 and DSS1 may be supported through
         appropriate software loads.

     .   The V5.1 network interface as specified in ETS 300-324-1 is used for
         the presentation of traffic at a non-concentrated interface. The V5.1
         interface supports both POTS and ISDN services.

     .   The V5.2 network interface as specified in ETS 300-347-1 is used for
         the presentation of traffic at a concentrated interface. The V5.2
         interface supports both POTS and basic rate ISDN services. The AC
         supports V5.2 groups of up to 16 E1 links.

      .  The AC supports dedicated data services using 64kbit/s timeslots.
         Cross-connect at the 64 kbit/s level from any input / output port is
         configurable via the management systems.
<PAGE>

4.3.2.   THE RADIO (CELL) SITE

         The network-side (backhaul) interface to the Central Terminal is up to
         4 x 2Mbit/s G703 / G704 interfaces. This is connected to the Access
         Concentrator or directly to the Switch. In the DA system this backhaul
         supports concentrated and compressed traffic.

4.3.3.   THE SUBSCRIBER SITE

         This is normally country specific in line with the national customer
         terminal interface specification(s), and versions are available that
         meet most requirements.

4.4.     EQUIPMENT OVERVIEW

     Airspan's systems consist of four main network elements:

     .   The Subscriber Terminal (ST) which is located at the end-user's
         premises.

     .   The Central Terminal (CT) which is located at the radio site or at the
         switch site.

     .   The Access Concentrator (AC) which is normally located at the switch
         site. This is only required for the Demand Assigned version of the
         system.

     .   The Management system (EM or SC) which is normally located at an
         Operator's network management center.


4.4.1.   SUBSCRIBER TERMINALS

     The portfolio includes 2 subscriber terminal types: internal and external

                              [GRAPHIC APPEARS HERE]
<PAGE>

     4.4.1.1.  THE SUBSCRIBER TERMINAL - EXTERNAL

     The external ST consists of an outdoor wall or pole mounted Customer Radio
     Unit (CRU) , an indoor AC Power Supply Unit (ACPSU) and termination jacks
     (NTU) into which end-users plug standard Customer Premises Equipment, as
     shown in the figure below:

                              [GRAPHIC APPEARS HERE]



     There is a range of external STs available, each supporting different
     services and numbers of lines:

     The ST-V2 supports two 64kbit/s analogue telephony lines at the end-users
     premises. This ST may operate in either Fixed or Demand Assigned modes.

     The ST-V4 supports four 32kbit/s analogue telephony lines at the end-users
     premises. This ST is optimized for pole mounting and may operate in either
     Fixed or Demand Assigned modes.

     The ST-I1 supports a basic rate ISDN,  2B+D (2 x 64kbit/s + 16kbit/s ) "S"
     interface, and normally operates in Fixed Assigned mode.

     The ST-D128 supports two 64kbit/s data channels on a G.703 interface, an
     optional converter can be used to provide either 2 x 64kbit/s V.35, 2 x
     64kbit/s X.21 or 128kbit/s interfaces for data applications.

     The ST-M120 is a multi-line terminal that allows the provision of up to 120
     VF "graded telephony" lines to an end-users premises. Lines are provided in
     modules of 6.

     The ACPSU can be supplied with or without backup batteries.

     4.4.1.2.  THE SUBSCRIBER TERMINAL - INTERNAL

     The architecture of the internal ST is different from the external ST in
     that the outdoor radio unit includes only the antenna and an RF front end.
     The outdoor unit is therefore smaller, lighter and easier to install in
     most applications. The majority of the electronics is in the indoor
     enclosure. This is connected to the outdoor unit by a drop cable.


                              [GRAPHIC APPEARS HERE]
<PAGE>

       There is a range of Internal STs available, each supporting different
       services and numbers of lines.

       The ST-R1 supports one 32kbit/s or 64kbit/s analogue telephony line at
       the end-users premises. Provisioning is by the management system.

       The ST-R2 supports two 32kbit/s or 64kbit/s analogue telephony lines at
       the end-users premises. Provisioning is by the management system.

       The ST-B1 supports a basic rate ISDN, 2B+D (2 x 64kbit/s + 16kbit/s ) "S"
       interface, and normally operates in Fixed Assigned mode.

       The ST-L128 supports 654kb/s or 128 kb/s clear channel data services via
       an RS530 interface.

       Internal STs are powered from the AC mains supply, with or without backup
       batteries.

4.4.2. THE CENTRAL TERMINAL

       The CENTRAL TERMINAL (CT) is the Base Station. This is deployed in omni
       or sectored cell configurations supporting variable numbers of STs per
       cell. The CT is a multi-service platform hosting single and dual line
       telephony, multi-line telephony, digital data leased lines and ISDN basic
       rate interfaces. The CT can operate in two modes, depending on the type
       of service and traffic levels supported. Fixed Assignment is used when
       STs must have a dedicated radio link. Demand Assignment is utilized when
       STs can share the available radio resources, and sustain an "engineered"
       grade of service.

       The CT provides the traffic interface to the network switching, either
       directly for Fixed Assigned systems or via the Access Concentrator for
       Demand Assigned systems. The CT also provides an interface to the
       management systems.

4.4.3.   THE ACCESS CONCENTRATOR

     The Access Concentrator (AC) is required when the system is operating in
     "Demand Assigned" mode to de-multiplex the traffic concentrated on the air-
     interface for presentation to the network switching equipment. Also in
     system versions using 32kbit/s compression the decompression to 64kbit/s is
     performed within the AC.

4.5. THE MANAGEMENT SYSTEMS

     Airspan's Management systems monitor, test and configure the WFA systems:

     .  SiteSpan Site Controller: a standalone "CRAFT terminal" for
        installation, operation and maintenance of the system.

     .  SiteSpan Manager: a scaleable, distributed PC based management system.

     .  Element Manager (SNMP): a centralized, UNIX based management system.


                              [GRAPHIC APPEARS HERE]

For Demand Assigned systems, interfaces for connection to the management system
are supported as follows:
     .  AC: 2 x RS232, 9600 baud

     .  AC: 2 x Ethernet, optional

     .  CT modem shelf: 2 x RS232, 9600 baud

     .  CT modem shelf: 1 x Ethernet, optional

     .  CT modem shelf: embedded within E1, backhauled to the AC.

Management communications routing is flexible.  The AC supports consolidation of
management communications from dependent CT equipments to provide a single
management interface.

5.   SYSTEM AIR INTERFACE

5.1. CDMA TECHNOLOGY

     Airspan's systems use a radio air-interface, specifically designed for
     Wireless Fixed Access to provide high quality, and low delay bearers for
     telephony, data and ISDN services

     The systems use Direct Sequence Spread Spectrum Code Division Multiple
     Access (DS-CDMA) on the air-interface between the CT and STs, allowing
     multiple radio links to share the same RF channel. A set of specialized
     codes is used which are shared between the ST and its corresponding modem
     in the CT.

     There are two stages to the CDMA modulation / demodulation process. Firstly
     direct sequence spreading is performed on each individual radio link by a
     pseudo-random noise (PN) code. Then multiple access, where multiple links
     share the same RF channel, is achieved by using a set of orthogonal
     Rademacher - Walsh (RW) codes. The PN and RW codes are combined into a
     unique and shared composite code used to modulate and demodulate each radio
     link.

     Airspan's systems implement a version of CDMA optimized for fixed access
     This is significantly different from other commercial CDMA implementations,
     such as IS-95, which are optimized for mobile cellular and PCS
     applications.

     The following table demonstrates the difference in implementation and
     performance between the two systems:

5.2.  AIR-INTERFACE STRUCTURE

      The system's Radio Interface structure supports both "Fixed" and "Demand"
      assignment of radio channels. The air-interface protocol and structure is
      compatible between both assignment types. The basic structure of the
      interface is shown below:

                              [GRAPHIC APPEARS HERE]


                         SYSTEM AIR-INTERFACE STRUCTURE

      Depending on the service applications and traffic levels to be supported,
      this structure is used in two different ways:


5.2.1. FIXED ASSIGNMENT

      The "Fixed Assigned" radio interface makes a permanent allocation of a
      radio link, operating within a RF channel to a subscriber terminal. Each
     link provides up to 144kbit/s of User Payload and 16kbit/s of OAM. In
     telephony applications where the subscriber is "on-hook" the ST will use
     "rate switching", reducing the link bandwidth to 10kbit/s, and hence
     decreasing the level of Access Noise on the RF channel.  For Fixed Assigned
     telephony applications each subscriber terminal supports 2 subscriber
     circuits.

                              [GRAPHIC APPEARS HERE]

                    FIXED  ASSIGNED  AIR-INTERFACE STRUCTURE
<PAGE>

5.2.2. Demand Assignment

       The "Demand Assigned" Radio interface makes a temporary call by call
       assignment of channels, to Subscriber Terminals in residential telephony
       applications, where the per line traffic allows the provision of Graded
       Service. The radio interface differs in that links are allocated as
       either Traffic, or Control channels.

                              [GRAPHIC APPEARS HERE]

                    DEMAND ASSIGNED AIR-INTERFACE STRUCTURE

      Within each RF Channel a pool of traffic channels (TCH) supports a mix of
      32, 64, and 144kbit/s services. Pool management is dynamic so that
      channels may be made available as 32, 64, and 144kbit/s on demand. The
      size of the traffic pool is automatically and dynamically sized based on
      radio interface performance and the grade of service requirements thus
      controlling the level of Access Noise. The pool can be extended if the
      interference level permits, or reduced if access noise is too great. The
      DA access protocol can also support one or more priority channels which
      allow guaranteed access for emergency calls. The channels allocated to
      traffic are pooled and configured as either 10 - 13 x 144kbit/s, 20 - 26 x
      64kbit/s, or 40 - 52 x 32kbit/s. Two links are reserved for OAM and Call
      Control.

      Each link operates using a master RW code to provide a 160kbit/s channel.
      These links are then sub-divided using 2nd level RW codes that allow the
      construction of 2 x 80kbit/s or 4 x 40kbit/s smaller granularity links,
      while maintaining the same Spectral Density. Hence TCHs are composed of
      either 160kbit/s, 80kbit/s or 40 kbit/s links.

      STs maintain communication with CT via the Call Control link, using an
      "Ethernet" like protocol. All STs are continually polled, and receive
      regular downloads of available TCHs and their channelisation (i.e.
      144kbit/s, 64kbit/s or 32kbit/s).

      STs track available TCHs to permit "fast acquisition". When a user's line
      goes "off-hook", STs request allocation of a TCH from the available pool.
      The CT instructs STs to "seize" a particular TCH, if access noise permits.
<PAGE>

      Traffic engineering is via the management system, which allows the
      following parameters to be programmed:

      .   Minimum / maximum number of traffic channels

      .   Number of access channels

      .   Demand access protocol type

      .   BER grade of service threshold

      .   Call blocking threshold

      .   Number of priority channels


5.3.  FREQUENCY RANGES SUPPORTED.

      Airspan's systems operate in various frequency ranges within the ITU-R and
      ETSI 2GHz and 3GHz frequency ranges. The specific channel plans available
      (see Appendix B) operate in frequency bands at:

      .   1.9GHz, in accordance with US PCS Band allocations

      .   2.0-2.3GHz, in accordance with CEPT/ERC/Rec. 13-01E, Annex C, with
          175MHz duplex spacing

      .   2.3-2.5GHz, in accordance with ITU-R 746, with 94MHz duplex spacing
      .   3.4-3.6GHz, in accordance with CEPT/ERC/Rec. 14-03E (Turku 1996), with
          100MHz duplex spacing

      The systems operate in Licensed spectrum, normally co-ordinated with other
      users by the licensing authority. Coexistence with other systems is in-
      line with ETS 301 055 and 301 124.


5.4.  RADIO LINK BUDGET

      Airspan's systems operate in rural, suburban and urban areas in either
      omni-cell or sectored cell configurations.

      System performance is governed by the link loss relative to available Link
      Budget. Therefore for shorter links Line Of Sight (LOS) propagation is not
      necessarily required and Near Line Of Sight (NLOS) links operate
      satisfactorily.

      The system range is dependent on the location and ground height of the CT
      sites and tower heights, relative to the ST locations and the environment
      in which the system is operating. Ref. 5.5.

       Maximum path loss (j=a+b+c-d)                               134.5  dB
       Fade margin for 99% Link availability                      4 - 10  dB

5.5.  CELL PLANNING CRITERIA

     Airspan's portfolio includes AirPlan, an RF coverage prediction tool which
     is used to optimize CT site locations for area coverage. See section 9.

     The system range depends on the propagation conditions which are a function
     of the environment in which the system is deployed:

     .   In a Rural environment 2nd order propagation is assured, giving a range
         of typically 8 - 15km. Line density is typically 1 - 10 per km2.

     .   In a Sub-urban environment 3rd order propagation is assured, giving a
         range of typically 5 - 8km. Line density is typically 10 - 100 per km2

     .   In an Urban environment 4th order propagation is assured, giving a
         range of typically 3 - 5km. Line density is typically 100 - 500 per
         km2..
<PAGE>

     Typical planning parameters used are as follows:


     Propagation prediction model                   See comments below

     Link Availability %                            99%

     Required C/I for frequency allocation          8.0dB

     Frequency reuse for maximum load               N = 3

     Minimum RF spacing, one sector                 Adjacent plus One - 7MHz

     Minimum RF spacing, one site                   Adjacent - 3.5MHz

     Guard band requirements                        Per CEPT / ITU channel plan

     The system adheres to the typical microwave propagation model, i.e. for
     rural areas:

     Path Loss = 32.44 + 20Log D + 20Log F, assuming 0.6 FZC is achieved.

     Testing has shown that the impact of an obstruction on the system closely
     mirrors theoretical work on propagation modeling by ITU-R (CCIR) for
     microwave point-to-point systems in the 2 and 4GHz bands.

     The model that best describes the effect of grazing on the radio path is a
     derivative from a "multiple knife edge diffraction" model. The basic work
     on this model was done by Bullington in 1947, and was finally refined by
     Deygout in 1966, when it appeared in CCIR Report 715. This methodology is
     an extension of a single knife edge diffraction calculation.

     In 1971 ASIS showed how this approach could be extended using "multiple
     rounded obstacles", in place of multiple knife edges. This is the basis for
     the Airspan's propagation model. The technique employed to calculate these
     type of losses is defined in CCIR Rec. 526-2, and involves representing the
     path as a series of  "cascaded cylinders".

<PAGE>

6.3.     ACCESS TO THE INTERNET

         The following options are currently supported by the system:

         .  Use of in-band data modem on a circuit switched basis

         .  Use of ISDN on a circuit switched basis

         .  Use of leased lines on a dedicated basis

         Use of packet based access in conjunction with circuit switched
         telephony service is a future feature.

6.3.1.   PACKET ACCESS CAPABILITIES.

         The Demand Assigned system has a number of characteristics which make
         it highly suitable for packet based Internet access.

         .  Residential Internet access is mostly asymmetric, with
            downstream traffic typically 10 times upstream rate. The
            system has greater capacity on the CDMA downlink than on CDMA
            uplink.

         .  The ST already contains a digital interface (i.e. RS-232 link)

         .  The ST will operate at up to 384kbit/s. STs can receive data
            on multiple RW links, making the potential bandwidth of any
            digital service up to 384kbit/s downstream and up to 128kbit/s
            upstream.

         .  In this application the system is "end-to-end digital" -
            removing analogue A/D and offering improved performance
            compared with copper/voice band modem solutions.

         .  The system has error protection facilities that can ensure
            high quality data delivery.

         .  The system has built-in HDLC facilities that enable the system
            to support packet data access.

                            WIRELESS INTERNET ACCESS
<PAGE>

6.4.     HIGH BANDWIDTH TRANSMISSION.


         .   Up to 384kbit/s is supported to an ST to support video and
             multi-media applications.

         .   The next generation implementation will in addition support
             user bit rates of up to 2Mbit/s, and will therefore offer
             operators a radio-based alternative to copper-based DSL
             systems - extending the range of DSL service beyond that of
             copper.


6.5.     SPEECH CODING

         The system is based on either 64kbit/s PCM, to support full wireline
         equivalent services, or 32kbit/s ADPCM for those applications where
         higher line density and quasi-wireline services are required.


6.6.     System Security

         ST authentication is carried out on a per call basis. Authentication
         uses encryption techniques to prevent an authentication response from
         being decoded and mimicked. An authentication request is issued by the
         CT equipment, which transmits a random code to the ST. The ST response
         is formed by non-linearly combining the random code with a known key.
         The key used for authentication comprises a static portion based on an
         unalterable electronic serial number (ESN) and a dynamic portion, which
         is updated following each authentication. Full authentication is
         delayed until the time critical phase of call set-up has been
         completed.

         Authentication failure causes an alarm to be generated. Service
         blocking on authentication failure is configurable via the management
         system.

         The ST serial number contains a portion which is unique and
         unalterable, i.e. not held in a memory that could be altered or
         duplicated. This portion of the serial number is 32-bits in size.

7.1.3.   DYNAMIC FREQUENCY ALLOCATIONS

         Where multiple RF channels are supported from a single CT equipment,
         then STs will be offered service from all RF channels to support:

         .   Fault tolerance: should a CT modem shelf fail, an ST may
             automatically switch to an alternative frequency for service
             for the duration of outage

         .   Increased trunking efficiency of the air-interface

         .   Traffic load balancing: An ST may be moved through manual
             intervention using the management system in order to balance
             traffic load across multiple CTs

         .   Frequency diversity: An ST may be moved through manual
             intervention using the management system in order to improve
             radio link performance

         At provisioning, an ST will be allocated a 'home' CT shelf (RF Channel)
         through which all usual management communications may be directed. The
         ST will be notified of other potential RF channels via management
         communications.

9.  RF AND DEPLOYMENT PLANNING

The use of radio to replace the traditional use of copper in the access network
requires modifications to an operator's normal deployment planning process, with
emphasis on radio coverage and frequency planning aspects.

As an aid to this planning process a fully equipped RF planning tool, called
AirPlanTM, including all necessary hardware and software can be supplied. The
AirPlanTM tool maps end-users to cell-sites based on the anticipated traffic
levels.


                              [GRAPHIC APPEARS HERE]



Thorough implementation of the RF planning process will provide an operator with
a high degree of confidence that satisfactory radio coverage can be achieved at
the desired ST locations from a given CT, or set of CT locations. Due to the
nature of radio propagation trees or other buildings in the vicinity of a
particular end-user location may affect the signal level at that location.
Therefore, the planning process cannot guarantee the viability of an end-user
connection, and certain local checks are required prior to the installation of
an ST on an end-user's building.

INFRASTRUCTURE:

The WLL System infrastructure (Central Terminals and Access Concentrators) are
designed to support 5,000 lines (or ISDN / Data equivalents). This is achieved
using a Base Station (Central Terminal) and Switch (Access Concentrator)
configuration as shown below.


                            [GRAPHIC APPEARS HERE]


            The Initial 5k Infrastructure - Operates 9 RF Channels.

Each Base Station consists of 6 Racks.

Three racks contain an RF Combiners, and two Fixed Assigned (FA) Modem Shelves
for ISDN and Data. The RF Combiner is equipped with Dual DIP/LNA enabling two
antennas per RF Combiner.

The other three racks contain one Demand Assigned (DA) Modem Shelf and one rack
alarm. Space is available for an upgrade to two Demand Assigned Modem Shelves.

Each Base Station operates from 6 Directional Antennas. The Antennas are high
gain and have an HPBW of 65 degrees.

Each Base Station is supported by its own Access Concentrator.

Access Concentrators are installed at two locations, 4 Access Concentrator in
two racks on one switch site, and 5 Access Concentrators in 3 racks on another.

Each Base Station is linked back to the swith site using
9, 2Mbit/s G.703 / G.704 transmission links.

SURVEY TOOL / INSTALLATION AID

The Airspan Survey Tool provides for the efficient planning of CRU location at
the Subscriber Terminal. It may also be used as a tool for surveying the signal
coverage area of a given Central Terminal.

            [GRAPHIC APPEARS HERE]         [GRAPHIC APPEARS HERE]

It consists of a telescopic mast attached to a tripod base, CRU, Drop Cable, and
a Test Box. The mast is erected as near to a probable CRU location as possible
and is raised to the mounting height of the CRU. The CRU is panned to assess the
signal strength at that location. The test box gives a readout of the values of
AGC and Power Control readings that can be related to the levels recorded on the
CRU calibration label. Details of the position, height, and panning angle can
then be recorded for use by the installer.

The Level Control Unit (LCU) can be used in two ways. This first is for system
commissioning the second is the ongoing maintenance of a System. The LCU basic
operation is poll each modem shelf (RF channel) on a hourly or daily basis to
ensure the receiver setting is at its optimum. This ensures system performance
is maintained at all times.

One Level Control Unit may be shared by up to four modem shelves in a single
rack.

The Level Control Unit operates by periodically acquiring a full low rate RF
downlink / uplink through RF cabling coupled into the CT transmit / receive
antenna ports. Knowledge of the path loss between the Level Control Unit and RF
antenna port allows the LCU to instruct the Shelf Controller to adjust RF
receive level as required.

The level control unit is an optional item

ANNEX 8 - OPTIONAL EQUIPMENT AND SOFTWARE
- -----------------------------------------

Radio Planning Tool - AirPlan

Radio Planning and Network Design for an Airspan deployment is based on the use
of AirPlan, Airspan's RF Planning Tool. AirPlan is a software tool that runs on
a Unix workstation that allows the operator to predict the radio coverage
Airspan equipment will attain in any given area. The results of the planning
process will be both a paper representation (in the form of reports and coverage
maps) and a Digital Model developed on AirPlan. The ongoing operational
management and extension of the Airspan network can be based on the use of this
software.

Two versions of the software are available for purchase

AirPlan Lite      =        50 Sites (Max. 150 Central Terminals).
AirPlan           =        500 Sites (Max. 1500 Central Terminals)

     charges in advance of shipment. Unless specified in the Purchase Order,
     Airspan will select the mode of shipment and the carrier.

     In this Agreement, "Incoterms" means the most recent international rules
     for the interpretation of trade terms published by the International
     Chamber of Commerce as in force on the Effective Date.  Unless the context
     otherwise requires, any term or expression which is defined in or given a
     particular meaning by the provisions of the Incoterms shall have the same

          the Equipment is the property of Airspan;

          b.  Purchaser shall not purport to create any security, mortgage,
          lien or pledge over the Equipment, or otherwise deal with the
          Equipment without Airspan's written consent;

          c.  In the event of any threatened seizure of the Equipment by any
          third parties, and on termination or expiration of this Agreement, or

          without prejudice to any other remedy, to enter without prior notice
          any premises and to repossess and take away or otherwise deal with the
          Equipment.

     5.5  The Software shall at all times remain the exclusive property of
     Airspan, subject to the uses provided herein.

     5.6  Unless Purchaser clearly advises Airspan to the contrary in writing,

<PAGE>


     said installment, provided that said delay does not exceed sixty (60) days
     from Airspan's scheduled ship date and unless Purchaser has clearly advised
     Airspan to cancel the delayed installment in writing at least fifteen (15)
     days prior to its revised planned shipment date or its actual shipment date
     by Airspan.

     5.7  Airspan will use reasonable efforts to meet Purchaser's requested
     delivery schedules for Equipment and Software, but Airspan reserves the
     right to refuse, or delay delivery to Purchaser when Purchaser's credit is
     impaired, when Purchaser is delinquent in payments or fails to meet other
     credit or financial requirements reasonably established by Airspan, or when
     Purchaser has failed to perform its obligations under this Agreement.

     5.8  Should orders for Equipment and Software exceed Airspan's available
     inventory, Airspan will allocate its available inventory and make
     deliveries on a basis that Airspan deems equitable, in its sole discretion,
     and without liability to Purchaser on account of the method of allocation
     chosen or its implementation. In any event, Airspan shall not be liable for
     any direct, indirect, consequential, or special losses or damages
     (including, but not limited to, loss of income or profit and loss of data)

shall have been given to the breaching party by the aggrieved party, the
aggrieved party shall be entitled at its option:  (a) if the aggrieved party is
Purchaser, to suspend its performance under Section 4 of the Agreement for as
long as the breach continues uncorrected; or (b) if the aggrieved party is
Airspan, to suspend performance of all of its obligations under the Agreement
for as long as the breach continues uncorrected; (c) to avail itself of any and
all remedies available at law or equity whether or not it elects to suspend its
performance under Section 15.2(a) or 15.2(b) as applicable; or (d) to terminate
this Agreement.

     15.3  In the event (a) either party fails timely to discharge its
obligations under this Agreement and (b) the aggrieved party employs a lawyer in
order to collect any amount due and unpaid or to enforce any right or remedy
hereunder, then the defaulting party agrees that, in addition to all amounts due
hereunder, it shall pay all costs of collection or enforcement including court

1 EXECUTIVE SUMMARY



This document describes Airspan Networks Inc. (Airspan)'s Wireless Fixed Access
(WFA) systems. These systems meet the requirements of network operators who wish
to offer copper-equivalent services via radio.

Airspan's systems were created to:

 .    Support a complete range of telecommunication services including telephony,
     Group 3 and Group 4 facsimile, payphone, data modems, high-speed leased
     line data, Internet Access and basic rate ISDN.

 .    Be economical to deploy in urban, suburban and rural areas.

 .    Have capacity that can be easily expanded as the customer base grows.

 .    Minimise initial capital outlay.

 .    Operate in a Point-to-Multipoint system configuration.

 .    Conform to the ETSI standards EN 301 055 and 301 124 for CDMA Point-to-
     Multipoint systems in the 1-3GHz and 3-11GHz bands.



Airspan's systems are best described as a "flexible access tool" for network
operators to provide a variety of services to their end-user customers.
Significantly, they are able to provide services that are the same quality and
performance as wireline services, by supporting a transparent connection to the
operator's network.  The combination of voice coding at either 64kbit/s PCM or
32kbit/s ADPCM, Bit Error Rates (BER) of better than 1 x 10-6 and low delay
(typically 10ms), ensure that advanced telephony services, including G3
facsimile and high speed data modems (up to 56kbit/s) for Internet applications
are fully supported. They are also the only fixed WLL systems to fully support
basic rate ISDN service in the 2B + D channel format.

The latest enhancement to the AS4000 family is PacketDrive technology.  This
enables high speed data applications to be delivered to customers, so that users
have access to an `always on' internet connection delivering up to 512kbit/s,
together with one or two regular POTS lines for voice communications.

<PAGE>

Airspan's systems support numerous applications within both existing and new
telecommunications networks, and has been deployed in both developed and
developing country environments. For example:

 .    International CLEC operators who want to differentiate their services from
     incumbents by offering hybrid voice and high speed data.

 .    In developing countries to reduce the waiting list for telephony services,
     in residential, business and payphone applications. This enables rapid
     deployment of a low cost / high value telephony infrastructure that
     typically exceeds the quality and performance of existing copper access
     networks.

 .    In developed countries as a "copper alternative", to modernise the access
     networks, reduce operating costs and thus reduce the cost of universal
     service provision.

 .    In both developed and developing countries to provide a "local loop

2  WIRELESS FIXED ACCESS


2.1  SYSTEM OVERVIEW


Airspan's Wireless Fixed Access (WFA) systems are digital point to multipoint
radio access systems providing wireless access for fixed end-users to a
telecommunication operator's network.

AS4000 is specifically designed for Wireless Fixed Access applications.  AS4000
delivers a wide range of services, including telephony, voice-band
facsimile/data, basic rate ISDN, leased line data, and packet-oriented
interfaces for always-on internet connections.  Distances up to 25km can be
covered.  AS4000 is therefore an attractive alternative to traditional copper
"local loops" for the delivery of these services to end-users.  Furthermore it
is a better services platform than pure voice WLL systems or packet-only
configurations.



                          GENERAL SYSTEM ARCHITECTURE


<PAGE>

AS4000 uses point to multipoint microwave radio links between the individual
end-user's premises and the network operator's "local point of presence" as an
alternative to the copper pair "local loop".

The "local point of presence" would typically be the local exchange premises. If
greater flexibility or range is required, the Central Terminal (cell site)
equipment can be remotely located in a suitable building or an environmentally
protected wayside cabinet, and connected to the local exchange via radio, cable
or fibre digital transmission links.

Both Fixed Assigned (FA) and Demand Assigned (DA) modes of bandwidth allocation
between the Central Terminal and Subscriber Terminals are supported.

The range of services supported includes:

 .    Analogue telephony (POTS).

 .    Always-on TCP/IP connections.

 .    Voice-band Group 3 facsimile and data up to 33.6kbit/s (extending to
     56kbit/s where there are digital interfaces between Airspan and the switch
     network).

 .    Payphones, including pulse metering.

 .    CLASS services.

 .    64kbit/s and n x 64kbit/s leased line data services.

 .    Basic rate ISDN (2B + D).

A portfolio of Subscriber Terminals (ST) are available supporting one or more
lines at each end-user location.

2.2  CONFORMANCE TO STANDARDS


Airspan's WFA system architecture is in accordance with the ETSI standards EN
301 055 and 301 124 for Direct Sequence Code Division Multiple Access (DS -
CDMA) Point-to Multipoint digital radio systems as shown below:

<PAGE>

The ETSI standard permits an operator to use systems from different vendors. The
standard addresses:

 .    Interoperability on Radio interface: Spectrum Masks, Spurious Emissions,
     Receiver Specs, Co and Adjacent Channel Interference Performance are
     defined. Reference is made to relevant ITU-R and CEPT standards.

 .    Host Network Interconnection is covered by references to relevant ETSI V5.x
     standards and TMN standards.

 .    Subscriber Services and Interconnection is covered by reference to relevant
     ITU-T standards.

2.3  SYSTEM INTERFACES


Interfaces between the various elements of Airspan's systems are as follows:
2.3.1  THE CENTRAL OFFICE / EXCHANGE INTERFACE (VOICE & ISDN SERVICES)


The interface between the WFA systems and the switch is N x 2Mbit/s G703 / G704
(1 per radio carrier typically 4 per CT).

In the FIXED ASSIGNED mode the following signalling protocols are supported:

<PAGE>

 .    Channel Associated Signalling (CAS). Variants are available to interface
     with switches from Ericsson (AXE), Nortel (DMS-100) and Siemens (EWSD).
     Variants can be made available to interface with other manufacturers
     digital switches that have 2Mbit/s subscriber ports. This protocol also
     supports 2 wire analogue interfaces via channel banks, such as the LS-120.

 .    Common Channel Signalling (CCS). UK DASS2 is available to interface with
     GPT (System X) and Ericsson (AXE) switches. DSS1 signalling to support
     Euro-ISDN is available to interface with Alcatel (S12) and Ericsson (AXE)
     switches. In addition V5.1 is supported.

In the DEMAND ASSIGNED mode the Access Concentrator (AC) provides the primary
network interface which is N x 2Mbit/s, as per ITU recommendation G.703, short
haul 6dB, G.704 and ETSI ETS 300-166.

All signalling is digital using either Channel Associated Signalling (CAS) or
Common Channel Signalling (CCS) protocols. The DA system interfaces to digital
switching systems that have 2Mbit/s subscriber ports.

Support for 2-wire VF interfacing is via external channel bank equipment.

 .    Channel Associated Signalling. Support for timeslot 16 ABCD bit CAS is
     provided. Airspan's management systems allow for flexible configuration of
     the protocol, to interface with switches from various manufacturers.

 .    Common Channel Signalling. V5.1 and V5.2 are supported by the DA system.
     Proprietary protocols such as DASS2 and DSS1 may be supported through
     appropriate software loads.

 .    The V5.1 network interface as specified in ETS 300-324-1 is used for the
     presentation of traffic at a non-concentrated interface. The V5.1 interface
     supports POTS, ISDN and data services.

 .    The V5.2 network interface as specified in ETS 300-347-1 is used for the
     presentation of traffic at a concentrated interface. The V5.2 interface
     supports both POTS and basic rate ISDN services. The AC supports V5.2
     groups of up to 16 E1 links.

 .    The AC supports dedicated data services using 64kbit/s timeslots. Cross-
     connect at the 64 kbit/s level from any input / output port is configurable
     via the management systems.

 .    GR303 and T1 interfaces are also supported

<PAGE>

2.3.2  THE OPERATOR INTERFACES (TCP/IP NETWORKS)


 .    For operators deploying AS4000 with PacketDrive features, the network-side
     interconnect consist of 100bT connections on standard ethernet cable.

 .    This can be flexibly combined with voice and data interfaces 2.3.3 THE
     OPERATOR INTERFACES (LEASED LINE DATA NETWORKS)

 .    Standard G.703 2Mbit/s interfaces are presented to the network.

 .    The allocation of timeslots on the E1 connections can be managed and
     groomed via the cross-connect functions built into the AC.

 .    These interfaces may form part of a combined V5.x presentation, or may be
     presented on separate interfaces as desired. They can also be combined
     flexibly with PacketDrive network interfaces.

2.3.4  THE RADIO (CELL) SITE


The network-side (backhaul) interface to the Central Terminal is up to 4 x
2Mbit/s G703 / G704 interfaces. This is connected to the Access Concentrator or
directly to the Switch. In the DA system this backhaul supports concentrated and
compressed traffic.

2.3.5  THE SUBSCRIBER SITE


This is normally country specific in line with the national customer terminal
interface specification(s), and versions are available that meet most
requirements.

2.4  EQUIPMENT OVERVIEW


Airspan's systems consist of four main network elements:

 .    The Subscriber Terminal (ST) which is located at the end-user's premises.

 .    The Central Terminal (CT) which is located at the radio site or at the
     switch site.

 .    The Access Concentrator (AC) which is normally located at the switch site.
     This is only required for the Demand Assigned version of the system.

 .    The Management system normally consists of AS8100 clients, located at an
     Operator's network management centre, with AS8100 servers distributed
     throughout the network.


<PAGE>

2.4.1  SUBSCRIBER TERMINALS



                            SUBSCRIBER TERMINAL (ST)
                              (EXAMPLE SHOWS ST-R2)

2.4.1.1  THE SUBSCRIBER TERMINAL


The architecture of the ST comprises two principal units.  The outdoor unit
contains a directional antenna and RF front end.  This is small, light and easy
to install.  The remainder of the electronics is contained in a Service
Interface Unit, normally located inside a customer's premises. This is connected
to the outdoor unit by a coax drop cable.  A small 12VDC mains PSU completes the
installation.

<PAGE>

There is a range of STs available, each supporting different services and
numbers of lines.

 .    The ST-R1 and ST-S1 supports one 32kbit/s or 64kbit/s analogue telephony
     line at the end-users premises. Provisioning is by the management system.

 .    The ST-R2 and ST-S2 supports two 32kbit/s or 64kbit/s analogue telephony
     lines at the end-users premises. Provisioning is by the management system.

 .    The ST-P1V2 supports an always-on 10bT Ethernet RJ11 interface for
     connection to the internet, plus two 32kbit/s or 64kbit/s analogue
     telephony lines at the end-users premises. Provisioning is by the
     management system.

 .    The ST-B1 supports a basic rate ISDN, 2B+D (2 x 64kbit/s + 16kbit/s) "S"
     interface, and normally operates in Fixed Assigned mode.

 .    The ST-L128 supports 64kb/s or 128 kb/s clear channel data services via an
     RS530 interface.

 .    A number of MULTI-LINE STS are available, ranging from the ST-N4 4-line
     unit to the ST-M16 for up to 16 analogue POTS lines.

STs are powered from the AC mains supply, with or without backup batteries.

2.4.2  THE CENTRAL TERMINAL


The Central Terminal (CT) is the Base Station. This is deployed in omni or
sectored cell configurations supporting variable numbers of STs per cell. The CT
is a multi-service platform hosting single and dual line telephony, multi-line
telephony, digital data leased lines and ISDN basic rate interfaces. The CT can
operate in two modes, depending on the type of service and traffic levels
supported. Fixed Assignment is used when STs must have a dedicated radio link.
Demand Assignment is utilised when STs can share the available radio resources,
and sustain an "engineered" grade of service.

The CT provides the traffic interface to the network switching, either directly
for Fixed Assigned systems or via the Access Concentrator for Demand Assigned
systems. The CT also provides an interface to the management systems.

<PAGE>

2.4.3  THE ACCESS CONCENTRATOR


The Access Concentrator (AC) is required when the system is operating in "Demand
Assigned" mode to de-multiplex the traffic concentrated on the air-interface for
presentation to the network switching equipment. Also in system versions using
32kbit/s compression the decompression to 64kbit/s is performed within the AC.

2.5  THE MANAGEMENT SYSTEMS


Airspan's Management systems monitor, test and configure the WFA systems:

 .    STMON: a standalone "CRAFT terminal" for installation, operation and
     maintenance of the subscriber terminals.

 .    AS8100 Sitespan Manager: a scaleable, distributed PC based management
     system, that can be used for commissioning or full-scale management,
     including integration with an operator's OSS system.



For Demand Assigned systems, interfaces for connection to the management system
are supported as follows:

 .    AC: 2 x RS232, 9600 baud

 .    AC: 2 x Ethernet, optional

 .    CT modem shelf: 2 x RS232, 9600 baud

 .    CT modem shelf: 1 x Ethernet, optional

 .    CT modem shelf: embedded within E1, backhauled to the AC.

Management communications routing is flexible. The AC supports consolidation of
management communications from dependent CT equipments to provide a single
management interface.

3  SYSTEM AIR INTERFACE


3.1  CDMA TECHNOLOGY


Airspan's systems use a radio air-interface, specifically designed for Wireless
Fixed Access to provide high quality, and low delay bearers for telephony, data
and ISDN services

The systems use Direct Sequence Spread Spectrum Code Division Multiple Access
(DS-CDMA) on the air-interface between the CT and STs, allowing multiple radio
links to share the same RF channel. A set of specialised codes is used which are
shared between the ST and its corresponding modem in the CT.

There are two stages to the CDMA modulation / demodulation process. Firstly
direct sequence spreading is performed on each individual radio link by a
pseudo-random noise (PN) code. Then multiple access, where multiple links share
the same RF channel, is achieved by using a set of orthogonal Rademacher - Walsh
(RW) codes. The PN and RW codes are combined into a unique and shared composite
code used to modulate and demodulate each radio link.

Airspan's systems implement a version of CDMA optimised for fixed access. This
is significantly different from other commercial CDMA implementations, such as
IS-95, which are optimised for mobile cellular and PCS applications.

The following table demonstrates the difference in implementation and
performance between the two systems:

3.2    AIR-INTERFACE STRUCTURE

The system's Radio Interface structure supports both "Fixed" and "Demand"
assigned modes for allocation of radio capacity to users. The air-interface
protocol and structure is compatible between both assignment types.  The basic
structure of the interface is shown below:




                         System Air-Interface Structure


Depending on the service applications and traffic levels to be supported, this
structure is used in two different ways:

3.2.1  FIXED ASSIGNMENT


The "Fixed Assigned" mode makes a permanent allocation of a radio link,
operating within a RF channel to a subscriber terminal. Each link provides 32,
64, 128 or 144kbit/s of user payload together with OAM. In telephony
applications where the subscriber is "on-hook" the ST will use "rate switching",
reducing the link bandwidth to 10kbit/s, and hence decreasing the level of
Access Noise on the RF channel.

<PAGE>

                     FIXED ASSIGNED AIR-INTERFACE STRUCTURE

3.2.2  DEMAND ASSIGNMENT


The "Demand Assigned" Radio interface makes a temporary call by call assignment
of channels, to Subscriber Terminals in residential telephony applications,
where the per line traffic allows the provision of Graded Service. The radio
interface differs in that links are allocated as either Traffic, or Control
channels.



                    DEMAND ASSIGNED AIR-INTERFACE STRUCTURE

<PAGE>

Within each RF Channel a pool of traffic channels (TCH) supports a mix of 32,
64, and 144kbit/s services. Pool management is dynamic so that channels may be
made available as 32, 64, and 144kbit/s on demand. The size of the traffic pool
is automatically and dynamically sized based on radio interface performance and
the grade of service requirements thus controlling the level of Access Noise.
The pool can be extended if the interference level permits, or reduced if access
noise is too great. The DA access protocol can also support one or more priority
channels which allow guaranteed access for emergency calls. The channels
allocated to traffic are pooled and configured as either 10-13 x 144kbit/s, 20-
26 x 64kbit/s, or 40-52 x 32kbit/s. Two links are reserved for OAM and Call
Control.

Each link operates using a master RW code to provide a 160kbit/s channel. These
links are then sub-divided using 2nd level RW codes that allow the construction
of 2 x 80kbit/s or 4 x 40kbit/s smaller granularity links, while maintaining the
same Spectral Density. Hence TCHs are composed of 160kbit/s, 80kbit/s or 40
kbit/s links.

STs maintain communication with CT via the Call Control link, using an
"Ethernet" like protocol. All STs are continually polled, and receive regular
downloads of available TCHs and their channelisation (i.e. 144kbit/s, 64kbit/s
or 32kbit/s).

STs track available TCHs to permit "fast acquisition". When a user's line goes
"off-hook", STs request allocation of a TCH from the available pool.  The CT
instructs STs to "seize" a particular TCH, if access noise permits. Traffic
engineering is via the management system, which allows the following parameters
to be programmed:

     .    Minimum / maximum number of traffic channels

     .    Number of access channels

     .    Demand access protocol type

     .    BER grade of service threshold

     .    Call blocking threshold

     .    Number of priority channels

3.3  FREQUENCY RANGES SUPPORTED


Airspan's systems operate in various frequency ranges within the PCS, ITU-R and
ETSI 2GHz and 3GHz frequency ranges. The specific channel plans available (see
Appendix B) operate in frequency bands at:

     .    1.8 - 1.9GHz, for deployments in the PS A-Band with 80MHz duplex
          spacing

     .    2.0- 2.3GHz, in accordance with CEPT/ERC/Rec. 13-01E, Annex C, with
          175MHz duplex spacing

     .    2.3 - 2.5GHz, in accordance with ITU-R 746, with 94MHz duplex spacing

     .    3.6GHz, in accordance with CEPT/ERC/Rec. 14-03E (Turku 1996), with
          100MHz duplex spacing

<PAGE>

The systems operate in licensed spectrum, normally co-ordinated with other users
by the licensing authority. Coexistence with other systems is in-line with ETS
301 055 and 301 124.

3.4  RADIO LINK BUDGET


Airspan's systems operate in rural, suburban and urban areas in either omni-cell
or sectored cell configurations.

System performance is governed by the link loss relative to available Link
Budget.  Therefore for shorter links Line Of Sight (LOS) propagation is not
necessarily required and Near Line Of Sight (NLOS) links operate satisfactorily.

The system range is dependent on the location and ground height of the CT sites
and tower heights, relative to the ST locations and the environment in which the
system is operating. Ref. 5.5.

3.5  CELL PLANNING CRITERIA


Airspan's portfolio includes AS8100 AirPlan, an RF coverage prediction tool
which is used to optimise CT site locations for area coverage. See section 9.

The system range depends on the propagation conditions, which are a function of
the environment in which the system is deployed:

 .    In a Rural environment 2nd order propagation is assured, giving a range of
     typically 8 - 15km. Line density is typically 1 - 10 per km2.

 .    In a Sub-urban environment 3rd order propagation is assured, giving a range
     of typically 5 - 8km. Line density is typically 10 - 100 per km2.

 .    In an Urban environment 4th order propagation is assured, giving a range of
     typically 3 - 5km. Line density is typically 100 - 500 per km2.

Typical planning parameters used are as follows:

The system adheres to the typical microwave propagation model, i.e. for rural
areas:
Path Loss = 32.44 + 20Log D + 20Log F, assuming 0.6 FZC is achieved.

Testing has shown that the impact of an obstruction on the system closely
mirrors theoretical work on propagation modelling by ITU-R (CCIR) for microwave
point-to-point systems in the 2 & 4GHz bands.

The model that best describes the effect of grazing on the radio path is a
derivative from a "multiple knife edge diffraction" model. The basic work on
this model was done by Bullington in 1947, and was finally refined by Deygout in
1966, when it appeared in CCIR Report 715. This methodology is an extension of a
single knife edge diffraction calculation.

In 1971 ASIS showed how this approach could be extended using "multiple rounded
obstacles", in place of multiple knife edges. This is the basis for the
Airspan's propagation model. The technique employed to calculate these type of
losses is defined in CCIR Rec. 526-2, and involves representing the path as a
series of  "cascaded cylinders".

4.6  PACKET ACCESS CAPABILITIES WITH AIRSPAN'S PACKETDRIVE TECHNOLOGY


PacketDrive technology is a seamless extension of Airspan's AS4000 system.  With
PacketDrive enhancements, service providers can deploy complete, wireless
Internet access services in addition to their circuit-based services

PacketDrive terminals can be added incrementally to an AS4000-based network by
employing Airspan's existing CDMA air interface, with no changes at the Central
Terminal base-station. This innovation thereby permits smooth network evolution
for existing and new Airspan-based network operators.

PacketDrive permits users to enjoy high speed Internet access, at up 512 kb/s
download speeds, together with complementary voice services. The PacketDrive
terminal provides an Ethernet port for connection to a user's computer and up to
2 voice ports.

Sophisticated Quality of Service measures are provided by the AS8100 PacketDrive
enhanced management system, which allows bandwidth to be carefully controlled
and optimally allocated. Detailed service statistics are available for tariffing
purposes.

<PAGE>

 .    Residential Internet access is mostly asymmetric, with downstream traffic
     typically 10 times upstream rate. The system has greater capacity on the
     CDMA downlink than on CDMA uplink.

 .    The STs operate at up to 512kbit/s. STs can receive data on multiple RW
     links, making the potential bandwidth of any digital service up to
     512kbit/s downstream and up to 128kbit/s upstream.

 .    In this application the system is "end-to-end digital" - removing analogue
     A/D and offering improved performance compared with copper/voice band modem
     solutions.

 .    The system has error protection facilities that can ensure high quality
     data delivery.

 .    The system has built-in HDLC and TCP/IP facilities that enable the system
     to support packet data access.



                            WIRELESS INTERNET ACCESS


<PAGE>

4.7  SPEECH CODING


The system is based on either 64kbit/s PCM, to support full wireline equivalent
services or 32kbit/s ADPCM for those applications where higher line density and
quasi-wireline services are required.

4.8  SYSTEM SECURITY


ST authentication is carried out on a per call basis. Authentication uses
encryption techniques to prevent an authentication response from being decoded
and mimicked. An authentication request is issued by the CT equipment, which
transmits a random code to the ST. The ST response is formed by non-linearly
combining the random code with a known key. The key used for authentication
comprises a static portion based on an unalterable electronic serial number
(ESN) and a dynamic portion, which is updated following each authentication.
Full authentication is delayed until the time critical phase of call set-up has
been completed.

Authentication failure causes an alarm to be generated. Service blocking on
authentication failure is configurable via the management system.

The ST serial number contains a portion which is unique and unalterable, i.e.
not held in a memory that could be altered or duplicated.  This portion of the
serial number is 32-bits in size.

5.1.3  DYNAMIC FREQUENCY ALLOCATIONS


Where multiple RF channels are supported from a single CT equipment, then STs
will be offered service from all RF channels to support:

 .    Fault tolerance: should a CT modem shelf fail, an ST may automatically
     switch to an alternative frequency for service for the duration of outage

 .    Increased trunking efficiency of the air-interface

 .    Traffic load balancing: An ST may be moved through manual intervention
     using the management system in order to balance traffic load across
     multiple CTs

 .    Frequency diversity: An ST may be moved through manual intervention using
     the management system in order to improve radio link performance

<PAGE>

At provisioning, an ST will be allocated a 'home' CT shelf (RF Channel) through
which all usual management communications may be directed.  The ST will be
notified of other potential RF channels via management communications.

7  RF AND DEPLOYMENT PLANNING



The use of radio to replace the traditional use of copper in the access network
requires modifications to an operator's normal deployment planning process, with
emphasis on radio coverage and frequency planning aspects.

As an aid to this planning process a fully equipped RF planning tool, called
AirPlan(TM), including all necessary hardware and software can be supplied. The
AirPlan(TM) tool maps end-users to cell-sites based on the anticipated traffic
levels.

Thorough implementation of the RF planning process will provide an operator with
a high degree of confidence that satisfactory radio coverage can be achieved at
the desired ST locations from a given CT, or set of CT locations. Due to the
nature of radio propagation trees or other buildings in the vicinity of a
particular end-user location may affect the signal level at that location.
Therefore, the planning process cannot guarantee the viability of an end-user
connection, and certain local checks are required prior to the installation of
an ST on an end-user's building.

         provide its acknowledgment and acceptance of the Order, within such
         twenty-four (24) hour period, Company shall be deemed to have rejected
         the Order.

         4.4      Product Availability.

         (a)      Standard Lead Time. The lead time for delivery of forecasted
                  Products shall not exceed six (6) weeks after Company's
                  acceptance of an Order, provided that Motorola's orders are
                  not materially different from the volumes of Products to be
                  supplied under Motorola's forecast submitted to Company under
                  subsection 4.1. The lead time for delivery of non-forecasted
                  Products shall not exceed ten (10) weeks after Company's
                  acceptance of an Order.

         (b)      Emergency Support Lead Time. Upon a verbal, promptly followed
                  by a written notification or fax from Motorola that a Customer
                  requires an emergency order, Company shall make all
                  commercially reasonable efforts to ensure appropriate Products
                  are shipped to such Customer or Motorola, as agreed by the
                  Parties, within twenty-four (24) hours of such request.
                  Motorola shall provide Company with an Order number as soon as
                  reasonably possible after such request. Company shall, as soon
                  as reasonable, provide Motorola (or Customer, if requested by
                  Motorola) with a waybill number and carrier information.
                  Invoices for any emergency Orders shall be sent immediately to

         rescheduling of the delivery of an Order by notifying Company not less
         than fourteen (14) calendar days prior to the scheduled delivery date
         and Motorola will use best efforts to ensure that rescheduling happens
         no more than one time per order. In the event that Motorola requests an
         Order reschedule less than fourteen (14) days prior to shipment that
         reflects a delay of an order exceeding ninety (90) days, such Order
         shall be subject to Company's actual costs, but in no event exceed ten
         percent (10%) of


                                      -5-
<PAGE>

         the applicable order. Such rescheduling charges shall be invoiced to
         Motorola upon shipment of the Product.




         4.6

         (a)      Cancellation of Order. Motorola shall have the right to cancel
                  all or a portion of any Order placed with Company, at no
                  charge, if the Order is cancelled more than thirty (30) days
                  prior to the scheduled ship date. In the event of a
                  cancellation (except for Orders canceled in accordance with
                  Sections 7.2 Late Delivery, 7.3(c) Rejection, 22 Termination
                  or 29 Force Majeure), Company may invoice Motorola for a
                  cancellation charge as Company's sole and exclusive remedy for
                  cancellation of the Order.

                  If the order is cancelled thirty (30) days or less prior to
                  the scheduled ship date, the following cancellation charges
                  may be charged by the Company:

If the price for Products             Then the cancellation charge
cancelled  is in the following        shall be in an amount equal to
amounts ...                           the  actual charges incurred but
                                      shall not exceed the following
                                      percentage of the price of the
                                      Products for the Order in
                                      question:

Less than $1 million                  5%

$1 million or more but less than      7%
$10 million

$10 million or more                   10%


                  No Cancellation Charge shall be applied if the rescheduling of
                  the Order is attributable to any material non-performance of
                  Company in its obligations hereunder. In addition, in no event
                  shall Motorola be responsible for any charges related to any
                  manufacturing or ordering of services or materials by Company
                  done in advance of the factory lead time necessary to meet the
                  requested delivery date shown on such Order. Further, in the
                  event of a cancellation, Company shall take all reasonable
                  steps to reallocate Products to other Customers.

         (b)      Special Cancellation Charges. Notwithstanding the foregoing,
                  the following special cancellation charge schedule ("Special
                  Cancellation Charge Schedule") shall apply to Orders that
                  become subject to the Special Cancellation Charge Schedule
                  pursuant to the procedures set forth below:


If the price for Products             Then the cancellation charge
cancelled  is in the following        shall be in an amount equal to
amounts ...                           the  actual charges incurred but
                                      shall not exceed the following
                                      percentage of the price of the
                                      Products for the Order in
                                      question:

Less than $1 million                  10%


                                      -6-
<PAGE>

$1 million or more but less than      15%
$10 million

$10 million or more                   20%


                  In order for an Order to become subject to the Special
                  Cancellation Charge Schedule, it must, if accepted by the
                  Company and fulfilled in accordance with its terms, result in
                  a 300% increase in the Company's production rates over the
                  quarterly run rates. The run rate shall be calculated as the
                  average number of: Central Terminals, Access Concentrators and
                  Subscriber Units produced in the previous quarter. If an Order
                  meets the foregoing requirement, then the Company may, in
                  connection with its acceptance and acknowledgement of the
                  Order, indicate in writing to Motorola that such Order shall
                  be treated as being subject to the Special Cancellation Charge
                  Schedule; if Company fails to indicate in connection with its
                  acceptance and acknowledgement of the Order, the Order shall
                  not be subject to the Special Cancellation Schedule. If the
                  Company in its Order indicates that such Order shall be
                  treated as being subject to the Special Cancellation Charge
                  Schedule, Motorola shall have seven (7) business days to
                  indicate to Company its acceptance of such treatment; if
                  Motorola fails to indicate acceptance of such treatment within
                  such time period, the Order shall be deemed accepted and
                  subject to the Special Cancellation Charge Schedule. If
                  Motorola indicates its rejection of such treatment with seven
                  business days, the order shall be deemed to be cancelled and
                  of no further force and effect.

         4.7 No Minimum Purchase. This Agreement shall not be construed as a
         purchase order for any Products. Motorola is under no obligation to
         place orders for any minimum quantity of products. Notwithstanding the
         foregoing, Motorola will use reasonable commercial efforts to promote
         Company products and in the spirit of this Agreement, Motorola has
         purchased two (2) demo/lab systems.

         4.8 Factory Acceptance Testing. Company is responsible for the
         development of the factory acceptance test plan ("FATP") for the
         Products. The FATP must be submitted to Motorola for review and
         approval or comments four (4) weeks prior to the planned start of
         acceptance testing for Products to be delivered to Motorola under this
         Agreement. Motorola must provide its comments concerning the FATP, if
         any, within two (2) weeks and the FATP must be approved by both
         Parties, which approval shall not be unreasonably withheld, prior to
         the start of Product factory acceptance testing. The FATP will be a
         subset of Company's standard product verification testing. Factory
         acceptance testing will take place at Company's facilities. All
         Products shall be subjected to factory acceptance testing. Prior to
         factory acceptance testing, Company shall provide Motorola with a set
         of pre-FATP engineering release notes.

         4.9 Acceptance Criteria. The criteria that must be met by the Products
         in order for the Products to be deemed factory accepted shall be set
         forth in the FATP. Results of factory acceptance testing shall be
         recorded in a Manufacturing Test Report.

5.       Packaging and Shipping.

         5.1 Packing Lists. Company shall include a complete packing list for
         each Order stating Order number, Motorola's part number, Company's part
         codes, serial number(s) and/or applicable Software version, quantity
         and date shipped, and Company's invoice number. A copy of the
         Manufacturing Test Report, which shall be a subset of the FATP, shall
         also be packed with each Product. Configured Hardware should be
         identified by one unique part number. Preloaded Software must be
         identified by a separate part number which also identifies the Software
         version. A receiving checklist which includes a detailed diagram of the
         assembled Hardware shall also be packed in the shipment. For
         international shipments, two (2) packing lists shall be provided for
         each Order.

         5.2 Markings. Company shall mark the outside of all packages with
         necessary shipping information including Order number, part number,
         quantity shipped, addresses of Company and Customer or Customer's
         designee, and other requirements agreed upon between Motorola and
         Company. Company shall follow Motorola's reasonable instructions
         concerning the use of any Trademarks of Motorola, or any word or symbol
         likely to be confused with any Motorola Trademark, either alone or in
         any combination with another word or words. Further, when using the
         trademarks of Motorola, Company may only use the Trademarks of Motorola
         as directed by Motorola for labeling and shipping of the Product as set
         forth in Exhibit F.

         5.3 Packaging. All Products shall be packaged in such a manner to
         prevent physical damage (including damage from electrostatic discharge)
         to the Products during shipment and delivery assuming customary and
         normal standards of handling. Freight and insurance associated with the
         shipment of any replacement Products due to a failure of Company to
         properly package the Products shall be the responsibility of Company.
         Motorola and Company will agree to work together to determine the best
         method of supplying Motorola's logo and labels to Company. Such
         materials shall be supplied to the Company at no charge to the Company
         and shall be supplied at times and in quantities sufficient for Company
         to meet Motorola's Orders.

         5.4 FCA, Risk of Loss, Title. The FCA (as defined in Incoterms, 1990
         edition), point of shipment shall be at Company's origin in the UK.
         Title to Product Hardware and risk of loss of the Products shall pass
         to Motorola at origin/Company's plant upon Company's tender of delivery
         by Company to Motorola's designated freight forwarder or carrier. Title
         to the Software shall not pass to Motorola or its Customer at any time.
         Motorola shall pay all freight and insurance costs from point of origin
         on a pre-pay and add basis and all applicable customs duties and
         similar charges.

         5.5 Shipping. All items shall be shipped FCA, as specified above, in
         the manner specified in the Orders. If Company ships Products by a
         transportation method other than that specified on the Order, Company
         shall be liable for the difference, if any, between the cost of freight
         incurred and cost of freight which would have been incurred had Company
         complied with the Order's shipping instructions. In the event any
         shipment will not meet the delivery date (except as provided herein),
         routing may be changed to premium transportation at Motorola's request.
         In that event, Company shall bear the expense of any difference in
         freight cost for the premium transportation unless the failure to meet
         the delivery date is due to acts or omissions or delays of Motorola or
         its customers or due to force majeure events. Company will, at
         Motorola's request, drop ship product directly to Motorola's Customers
         worldwide.

         5.6 Motorola must inform Company of any loss in transit or damages(s)
         to the Equipment and Software, and co-operate with Company in filing
         any claims with the carrier for such loss in transit or damage(s).

         5.7 In this Agreement, "Incoterms" means the most recent international
         rules for the interpretation of trade terms published by the
         International Chamber of Commerce as in force at the date when this
         Agreement is made. Unless the context otherwise requires, any term or
         expression which is defined in or given a particular meaning by the
         provisions of Incoterms shall have the same meaning in this Agreement,
         but if there is any conflict between the provisions of Incoterms and
         this Agreement, the latter shall prevail.

6.       Foreign Regulatory Approvals and Export Controls.

         6.1 Regulatory Approvals. Motorola and Company will work jointly to
         obtain foreign government regulatory approvals for the Products. In the
         event that type approval or certification has not previously been
         obtained by Company, and is required (as reasonably agreed upon by the
         parties), Company and Motorola will work together to secure type
         approval and certification as required. In such circumstances, Company
         and Motorola shall equally split 50/50 all costs and charges associated
         with such approvals. However, each Party is responsible for their own

                                      -8-
<PAGE>

         internal costs associated with such type approvals or certification.
         Company shall be free to use such approvals in its other business
         activities.


         6.2 Export Controls. Motorola shall obtain all export licenses and
         other government authorizations necessary for the shipment of any
         Products with such assistance from Company as Motorola may reasonably
         request.

         forth in the Order. Delivery of Services shall be in accordance with
         agreed to milestones stated in the applicable Order.

7.2      Late Delivery.

         (a)      As soon as Company becomes aware that any delivery is likely
                  to be late, Company will promptly notify Motorola and keep
                  Motorola informed about the circumstances causing the delay.
                  In the event Company fails to make delivery on time, Motorola
                  may give Company notice of such delinquency, allowing Company
                  a reasonable time to cure. In no event shall such cure period
                  exceed fifteen (15) days from the originally scheduled
                  delivery date, unless otherwise agreed upon by the parties. In
                  the event Company fails to deliver any portion of the ordered
                  Products during such period, Motorola, at its option, may
                  cancel the undelivered portion of such Order at no charge.

         (b)      Liquidated Damages. In the event Motorola incurs late fees
                  from its Customers attributable entirely to the fault of
                  Company, Motorola, at its discretion, may invoice Company for
                  such liquidated damages. Company shall have no liability for
                  late fees, liquidated damages, or the like if the delay is
                  attributable to a Force Majeure Event or any default by
                  Motorola. Company shall incur no late fees, liquidated damages
                  or the like unless such fees or damages are imposed on
                  Motorola by its customer. Under no circumstances, even if
                  orders submitted by Motorola and accepted by Company provide
                  for late fees or liquidated damages that are higher, shall the
                  aggregate amount of late fees or liquidated damages for an
                  order exceed a maximum of fifteen (15%) of the value of the
                  delayed items under the applicable Order. The schedule for
                  payment of late fees or liquidated damages shall not exceed
                  the following: 0.5% per day of the value of the delayed items
                  under the applicable Order for each day of delayed delivery
                  after the date falling fifteen (15) days after the scheduled
                  delivery date, to the extent such delay is not attributable to
                  a Force Majeure Event or default by Motorola. In the event
                  that the system may be put into commercial service without the
                  delayed items, then the liquidated damages will be limited to
                  a cap of 15 % of the value of the delayed items. However, if
                  the delayed items prevent the system to be put into commercial
                  service due to the delay, then the 15% cap applies to the
                  value of the total system. Payment of late fees, liquidated
                  damages or the like shall be the sole exclusive remedy against
                  Company in respect to late delivery.

         7.3      Acceptance and Rejection.

         (a)      Delivery and Testing. When Company delivers Products to
                  Motorola or its Customers, Company shall provide a written
                  statement listing the items delivered and stating that they
                  are ready for Motorola's Acceptance Testing. Such statement of
                  readiness will be in Company's standard format and may be
                  accomplished via electronic transmission if stated in the
                  Order. Motorola and Company shall develop a joint Acceptance
                  Test Procedure ("ATP") and acceptance criteria, which shall be
                  based on the FATP, and incorporate such ATP herein as Exhibit
                  "C". Such Exhibit "C" shall be jointly approved by Motorola
                  and Company, which approval shall not be unreasonably
                  withheld, including how it will be applied to each such
                  Product delivery. At their sole option, Motorola, with the
                  assistance of Company for a maximum of three (3) Orders placed
                  by Motorola under


                                      -9-
<PAGE>

                  this Agreement, may examine, install and test the Products in
                  accordance with the ATP prior to shipment to Motorola's
                  Customers to determine whether the Products conform to the
                  applicable Product Order and Exhibit "B" Specifications.
                  Company shall assist Motorola in developing additional test
                  plans as may be required for new customers.

         (b)      Acceptance. After installation of a Product(s), Motorola's
                  deployment team may perform acceptance testing upon the
                  Product(s) to ensure that the Product(s) is properly installed
                  and substantially performing in accordance with the Product
                  Specifications. Acceptance testing shall include a detailed
                  demonstration of the Products by Motorola to the relevant
                  Customer. This demonstration will include an interactive
                  operation of the Products with the various components supplied
                  to the Customer, and will be deemed complete upon confirmation
                  by Motorola's deployment team that the Products are in proper
                  working order per the Product Specifications. Upon receipt of
                  such confirmation, Company shall, for a maximum of (3) Orders
                  placed by Motorola under this Agreement, assist Motorola
                  and/or the Customer in conducting acceptance tests using
                  simulated and/or actual data, at Motorola's discretion, for a
                  period not to exceed ten (10) days from the conclusion of the
                  Motorola Testing Period (the "Customer's Testing Period").
                  Within five (5) days after completion of Customer's Testing
                  Period, Motorola and Customer shall complete and execute a
                  Hardware Acceptance Checklist and a Software Acceptance
                  Checklist in the forms attached as Exhibit C (each a
                  "Checklist"), which shall state with specificity any aspects
                  of the Product(s)'s performance which do not substantially
                  conform to the Product Specifications. If the checklists
                  demonstrate that the Product(s) substantially conforms to the
                  Product Specifications, then such Product(s) shall be
                  considered accepted by Motorola and the Customer.

         (c)      Rejection. Motorola reserves the right to refuse delivery of
                  any Products which are not in material compliance with the
                  provisions of any Order or the material provisions of this
                  Agreement. Motorola, at its option may return, freight
                  collect, all Product received, which is not in material
                  compliance with the order or this Agreement, in its original
                  condition, to Company at Company's location in the UK or may,
                  at its option, retain such Product and make an appropriate
                  adjustment to the Purchase Order agreed upon by Company.

                  Incorrect or Dead on Arrival (DOA) Delivery. Company will use
                  all commercially reasonable efforts to deliver Product
                  replacement to Motorola or its designated freight forwarder,
                  or Customers ( as designated by Motorola) for materially
                  incorrect shipments or DOA (i.e. Products that materially fail
                  to perform "out-of-box" ) shipments within twenty-four (24)
                  hours of notice Motorola. If Company is unable to meet these
                  requirements, Company shall contact Motorola and the Parties
                  will mutually agree upon an alternative delivery schedule.

                  If Motorola properly rejects the installation of a Product(s)
                  pursuant to Section 7.3(b), then Company will work promptly,
                  diligently and continuously to correct the deficiencies such
                  that the Product(s) is performing substantially in accordance
                  with the Product Specifications as soon as reasonably
                  practicable thereafter. If the Product(s) is not so performing
                  within thirty (30) days following the rejection, Motorola may,
                  as its sole and exclusive remedy, cancel the Order, return at
                  Company's cost all of the Product, in its original condition,
                  ( except for ordinary wear and tear and necessary adjustments
                  for installation and de-installation) to Company at Company's
                  location in the UK, and receive a full refund of all fees paid
                  to Company for the Product(s) and associated services.

         (d)      The provisions of this Section 7 shall also apply to
                  installations of Hardware or Software on a Product(s) after
                  the initial installation of such Product(s), except that: (i)
                  for a maximum of three (3) Orders placed by Motorola under
                  this Agreement, Company and Motorola and/or its relevant
                  Customer shall first test the newly-installed Hardware or
                  Software and subsequently test the Product(s) after
                  integration of the newly-installed items; (ii) Motorola may
                  reject such newly-installed Hardware in the manner described
                  in


                                      -10-
<PAGE>

                  Subsection (b); (iii) Company shall have sixty (60) days to
                  correct the deficiencies with such Hardware or Software; and
                  (iv) if Company fails to do so, Motorola may terminate its
                  obligations with respect to such additional Hardware or
                  Software within thirty (30) days following expiration of such
                  60-day period, in which case Company shall refund to Motorola
                  all fees paid for such newly installed Product following
                  return by Motorola of the Products to the Company, in their
                  original condition, ( except for ordinary wear and tear and
                  necessary adjustments for installation and de-installation) at
                  the Company's location in the U.K..

         7.4 No Waiver. Neither Motorola's acceptance of partial shipments nor
         provision for delivery of Products in installments shall relieve
         Company of its obligations under this Agreement.

8.       Prices and Payment.

         8.1 Prices. The prices payable for the Products are as set out in
         Exhibit "A". Prices stated shall be firm fixed for orders placed during
         the initial term of this Agreement, and thereafter, for periods after
         the initial two year term, may be adjusted annually by the Company by
         notice given by Company to Motorola at least ninety (90) days prior to
         the then applicable contract expiration date. After the initial term of
         this Agreement, price changes shall not be made more often than once a
         year, effective on the anniversary of the Agreement Date unless agreed
         otherwise in writing by both Parties. Company shall provide Motorola
         ninety (90) days prior written notice of any intent to change its
         prices for Products from those set forth on Exhibit A. Nothing herein
         shall prevent the Company from adding new products and prices
         associated with those products to the price list and either during or
         after the initial term of this Agreement, setting prices for Upgrades
         and Products incorporating Upgrades.

         8.2 Payment Terms. All payments for the Products shall be made in U.S.
         dollars at the applicable prices detailed in Exhibit "A", and are due
         net forty-five (45) days after the date on which Motorola receives a
         correct invoice therefor. Company's invoices shall contain (i)
         Motorola's "Invoice to" and "Ship to" addresses as specified by the
         Order, (ii) Order number, (iii) applicable price(s) and discount, and
         (iv) reference to this Agreement. Payment of invoices shall not
         constitute acceptance of the Products and shall be subject to
         adjustments for shipment shortages and other failures of Company to
         meet the requirements of this Agreement.

         8.3 Late Payment Fee. Payments not made when due shall thereafter bear,
         at the option of the receiving party, interest at a rate equal to the
         lower of (x) 12% per annum, or (v) highest rate permitted by applicable
         law.

         8.4 Taxes. The prices set forth in Exhibit "A" for the Products do not
         include applicable sales, use, excise or similar taxes. To the extent
         Company is required by law to collect such taxes, they shall be a
         separate line item on invoices and paid in full by Motorola, unless
         Motorola is exempt from such taxes and furnishes Company with an
         appropriate certificate of exemption.

         8.5 Most Favored Customer. Notwithstanding any other provision of this
         Agreement, the prices, services and warranties granted by Company to
         Motorola pursuant to this Agreement taken as a whole are hereby
         warranted by Company to be comparable to or more favorable to Motorola
         than the comparable prices, services and warranties offered by Company
         to any of its other customers, purchasing the same Products in the same
         or substantially the same quantities, under substantially similar
         terms, during the term of this Agreement, including any renewal
         thereof. Upon discovery that Company is or has provided more favored
         prices, services and warranties, taken as a whole, to any other
         customer in violation of the foregoing, Company shall immediately
         provide notice to Motorola of such fact and this Agreement shall be
         deemed to be automatically amended to include such more favored prices,
         services and warranties, taken as a whole.

                                      -11-
<PAGE>

         8.6 If Company breaches the warranty in 8.5 above, Motorola's sole and
         exclusive remedy shall be for Company to provide the more favored price
         or warranties to Motorola, effective immediately, from the date
         Motorola or Company discovers the breach.


9.       Product Changes.

         9.1 Company shall provide Motorola ninety (90) days prior written
         notice of any intent to change: (a) any material changes in quality
         control for manufacturing processes for the Products; (b) any material
         functionality or physical characteristics of the Products; or (c) part
         number(s) before substituting Products with new numbers for Products
         ordered under old numbers. This does not include Modifications that are
         provided as part of normal maintenance Services.

         9.2 No Discontinuance. Company may not discontinue the production or
         availability of any Products at any time during the term of the
         Agreement without giving Motorola seven (7) months prior written notice
         (with details as to replacement products) or receiving the prior
         written approval of Motorola, which will not be unreasonably withheld.
         During such seven (7) month notice period, Motorola may purchase or
         license additional quantities of the Products being discontinued. In
         the event of a Products discontinuance under this Agreement, Company
         shall provide substitute Products which under normal and proper use:
         (i) shall not materially or adversely affect physical or functional
         interchangeability or performance (except where there is written
         agreement between the Parties that specific characteristics will be so
         affected), (ii) shall not detract from the safety of the Products, and
         (iii) shall be type-accepted by the appropriate authority, if required.
         Company will use all commercially reasonable efforts, subject to
         technology and vendor availability, to provide support for ten (10)
         years after notice of product discontinuance.

         9.3 Compatibility. Company shall use its commercially reasonable
         efforts to ensure that all Products, including any future releases
         thereof, shall be backwards compatible with, at a minimum, all
         current/inservice Products, both software and hardware, and any
         releases made available during the two (2) years prior to the date any
         new release is first made available to Motorola; and upwardly
         compatible with any future release of any Products which Motorola
         purchases or licenses under this Agreement.

         9.4 Change Order Process. Notwithstanding Section 9.3, any changes to
         Products after acceptance thereof which affect the technical
         functionality of the Products in any material respect must be submitted
         in writing (in the form of a "Change Order Request") to Motorola
         preferably within six (6) months but in no event less than four (4)
         months prior to the intent to implement the change. Motorola will
         review proposed changes within six (6) weeks of receipt of the Change
         Order Request. Motorola will respond in writing with an approval or
         alternative recommendation for the change. Proposed changes to Products
         Specifications (Exhibit "B") as well as the introduction of future
         Upgrades shall be subject to this change process. Such notice period
         shall not apply in the event that the change is implemented to
         introduce a bug-fix, repair or other modification to restore
         functionality to that of the product specification described in Exhibit
         B.

10.      Product Documentation.

         10.1 Documentation Deliverables. Upon execution of this agreement,
         Company shall provide Motorola with two (2) complete master sets of
         Documentation, of the type it generally provides to Customers of the
         Products, at no additional charge. Documentation shall also be provided
         to Motorola in a mutually agreed to electronic format. Company shall
         notify Motorola of Company's Product release notices so that Motorola
         may integrate such notices into the Documentation. Company shall
         further provide any content/page updates or revisions, and series
         numbers, if affected, on the date of their release for incorporation
         into the master set. Prior to the first commercial installation of the
         Products, Company and Motorola shall jointly develop a process for


                                      -12-
<PAGE>

         the delivery and revision of future documentation releases. Once
         integrated, Motorola shall provide Product Documentation to Company via
         electronic format and Company shall ship such integrated Documentation
         to Customers when drop shipping Products.

         10.2 Rights to Documentation. Company grants to Motorola a
         non-exclusive, worldwide, perpetual, royalty-free license to edit,
         reproduce and merge into other Product materials and Documentation or
         other written materials, including any revisions thereof, Documentation
         provided under this Agreement. Motorola shall be responsible for the
         final style edit and formatting, to ensure consistency with the overall
         Motorola documentation style, graphics and format. Motorola may use any
         Documentation internally, as well as sell or otherwise make available
         such Documentation to Customers. Company grants Motorola the right to
         remove any trademark, copyright or other notices which may appear in
         the body of any such Documentation and to place Motorola's own
         trademark, copyright and other notices on such Documentation. Company
         grants to Motorola all licenses under any copyrights or trademarks or
         other rights which may be necessary in order to provide the foregoing
         rights. Company is granted no rights in any Product Documentation or
         materials that contain edited, reproduced or merged Documentation.
         Motorola shall use the Documentation so licensed to Motorola only for
         purposes of providing sales , marketing, maintenance and support of
         Products sold by Company hereunder and for purposes of providing such
         Documentation to Motorola's Customers only for use in their maintenance
         and support of Products sold by Company hereunder.

         10.3 Language. Motorola and Company acknowledge and agree that the
         Documentation shall be in the English language. Motorola has the option
         to contract with Company to have the Documentation translated into one
         or more foreign languages at reasonable rates and terms. If Motorola
         translates the Documentation into a foreign language, Motorola shall
         provide a copy of the translation to Company and Company shall be free
         to use such translations, after removing Motorola trademarks and
         tradenames, in its other business activities.

11.      Training.

         11.1 Training Courses. Company shall provide an initial training
         courses up to a maximum of three (3) courses for Motorola's personnel
         to integrate, install, operate and maintain the Products and utilize
         any necessary test equipment for a maximum of twenty (20) employees or
         contractors of Motorola. Such courses shall be for a total of forty
         (40) hours ( 5 business days) per employee. One of these courses may
         include a "Train the Trainer" course. All slides and scripts developed
         by Company shall be made available in electronic format for use by
         Motorola at no charge, provided that Motorola shall use the same only
         for maintenance and training with respect to Products sold by Company
         under this Agreement. Motorola personnel sent to such courses shall
         have an appropriate technical background. Concurrent with the execution
         of this Agreement, Company and Motorola shall mutually agree on the
         date on which the initial training course shall commence. In any event,
         the initial training course shall commence within thirty (30) days of
         Motorola's reasonable request. Such course shall be made available at a
         location defined by Company and at no cost to Motorola. Company shall

         15.1 Company acknowledges that commitment to total customer
         satisfaction is essential to Motorola's continuing success in wireless
         radio markets. A malfunction in the Products or Services may create
         real or perceived customer satisfaction problems and a loss of goodwill
         with customers. It is agreed that such problems may be outside the
         scope of Company's warranty obligations set forth in this Agreement.

         fundamental objective of Total Customer Satisfaction and will assist
         Motorola in endeavoring to solve problems attributable to the Products,
         when reasonably requested by Motorola. Under no circumstances however
         is this Section, or Section 15.2, intended to give Motorola additional
         remedies for breach of Company's warranty or to expand Company's
         obligations with respect to Products out of warranty.

         15.2 By way of example, and not limitation, at Motorola's reasonable
         request, Company may be requested to periodically attend Customer
         meetings and/or symposiums for the purpose of promoting and responding
         to questions and concerns of Customers utilizing such Products, taking
         action items at such meetings and working with Motorola to endeavor to
         resolve customer satisfaction problems; be requested to attend on-site
         meetings with individual customers who may be experiencing unique
         difficulties with Products; etc. The parties shall mutually agree on
         the allocation of any expenses to achieve the foregoing.

16.      Intellectual Property Rights.

         16.1 IPR of Company. All patents, trademarks, copyrights, mask works,
         circuit layout rights, design rights, trade secrets and other
         intellectual property rights in the Products and Company's Confidential
         Information are and shall remain the exclusive property of Company or
         its licensor.

         16.2 IPR of Motorola. All patents, trademarks, copyrights, design
         rights, trade secrets and other intellectual property rights in
         Motorola's Confidential Information are and shall remain the exclusive
         property of Motorola or its licensors.

         16.3 Integration. Company shall not integrate or merge any Motorola

         unless necessary to provide support to Customers in the event that
         Motorola is provided Source Code pursuant to the escrow arrangement.
         Motorola acknowledges that, except pursuant to the escrow arrangement
         contemplated hereby, all Software provided hereunder will be provided
         in Object Code only. Motorola shall not decompile, disassemble or

         more rights concerning the Software than those contained herein, which

         disassembling or reverse engineering the Software.

         18.3 Right to Copy. Upon execution of this Agreement, Company agrees to

         copies made and sublicensed.

         18.4 Right to Use Source Code. Company grants Motorola a perpetual,

19.      Source Code Escrow.

         19.1 Source Code Obligation. Motorola may, at its option, enter into a
         Software Source Code escrow agreement with Company. Such escrow
         agreement shall state that Company shall deposit, concurrently with the
         execution of this Agreement and on each anniversary of the date of this
         Agreement, with a third party reasonably acceptable to the Company
         ("Escrow Agent"), the most recent Source Code of the Software. Under
         that agreement, in the event Company enters into any voluntary or
         involuntary receivership arrangement or other insolvency procedures
         (with appropriate cure periods for involuntary procedures, to be set
         forth in the Escrow Agreement, attached hereto as Exhibit K), or ceases
         to provide, in all material respects, substantially all of the support
         services required by this Agreement in respect of Products sold by the
         Company hereunder, such cessation continues after appropriate notices
         and cure periods as set out in the Escrow Agreement, and there is no
         successor to the Company undertaking such support, Motorola may direct
         the Escrow Agent to deliver to Motorola the deposited Source Code
         unless Motorola is then in material default under this Agreement
         according to section 22.1(a) (for these purposes, this Agreement and
         Orders placed thereunder shall be taken as a whole). It is understood
         that ownership of the Source Code at all times remains with Company and
         that any release to Motorola of such Source Code is made as an
         accommodation to Motorola and shall


                                      -19-
<PAGE>

         not vest any ownership or ownership rights in Motorola. In the event
         that receivership or insolvency proceedings are dismissed and Company
         continues as the primary obligor under this Agreement, Motorola, within
         twenty (20) working days of receiving notice thereof, shall return the
         Source Code and all copies to the Escrow Agent. During any period of
         time in which the Source Code is in the possession of Motorola, it is
         agreed that the Source Code shall be used only by Motorola and agents,
         such as subcontractors, and may be used and modified solely for the
         purposes of providing continuing support for Products sold by the
         Company under this Agreement; for avoidance of doubt, the Source Code
         shall not be used for development purposes nor duplicated, sold or
         licensed to others or marketed in any manner. Motorola agrees to pay
         all costs of entering into the Software Escrow Agreement and all annual
         renewal costs. Except as specified in this Section, Motorola shall have
         no access to the Source Code.

         19.2 Specific Performance. Company expressly agrees to promptly comply
         with the foregoing obligations and agrees that if Motorola, at its
         option, enters into such a Software Escrow Agreement, then Motorola
         shall be entitled to an order for specific performance of such
         obligation in the event Company's representative, including any trustee
         in bankruptcy, refuses to comply with the foregoing obligations. In the
         event of bankruptcy, the Parties acknowledge that Motorola shall be
         entitled to the full protection provided to licensees of intellectual
         property rights specified in 11 U.S.C. ss. 365.

20.      Confidentiality.

         20.1 Exchange of Confidential Information. From time to time during the
         performance of this Agreement, the Parties may deem it necessary to
         provide each other with Confidential Information. The Parties agree:

         (a)      To maintain the confidentiality of such Confidential
                  Information and not disclose same to any third party, except
                  as authorized by the original disclosing Party in writing.

         (b)      To restrict disclosure of Confidential Information to
                  employees, contractors, and agents who have a "need to know".
                  Such Confidential Information shall be handled with the same
                  degree of care which the receiving Party applies to its own
                  confidential information but in no event less than reasonable
                  care.

         (c)      To take precautions necessary and appropriate to guard the
                  confidentiality of Confidential Information, including
                  informing its employees, contractors and agents who handle
                  such Confidential Information that it is confidential and not
                  to be disclosed to others.

         (d)      That Confidential Information is and shall at all times remain
                  the property of the disclosing Party. No use of any
                  Confidential Information is permitted except as otherwise
                  expressly provided herein and no grant under any proprietary
                  rights is hereby given or intended, including any license
                  implied or otherwise.

         20.2 Responsibilities as to Employees. The receiving Party acknowledges
         that Confidential Information may contain information that is
         proprietary and valuable to the disclosing Party and that unauthorized
         dissemination or use of the Confidential Information may cause
         irreparable harm to the disclosing Party. Therefore, the receiving
         Party shall take appropriate action, by instruction, agreement or
         otherwise, with any employee or contractor permitted access to the
         Confidential Information so as to enable it to hold the Confidential
         Information in confidence or otherwise satisfy its obligations under
         this Agreement.

         20.3 Survival. Each Party's obligations under this Agreement to keep
         confidential and restrict use of the other Party's Confidential
         Information shall survive the expiration or termination of this
         Agreement for a period of five (5) years.

         20.4 Disclosure. Except as may be required by applicable law, neither
         Party shall disclose to any third party the contents of this Agreement
         or any amendments hereto without the prior written


                                      -20-
<PAGE>

         consent of the other Party. The foregoing shall not prevent disclosure
         to a Party's accountants and lawyers.

         20.5 Independent Development. Company acknowledges that Motorola and/or
         third parties are, or may be developing, Products similar in
         functionality to those developed hereunder by Company. Company agrees
         that the receipt of Confidential Information by Motorola from Company
         shall in no way prohibit Motorola and/or third parties from developing
         such applications, provided that the provisions of this Section 20
         regarding the ownership, protection and security of Company's
         Confidential Information have not been breached.

                  21.1 which a third party seeks to recover from Motorola as a
                  result of actual or claimed infringement but are intended to
                  limit Motorola's recovery by indemnity for damages of the type

                  contemplated by Section 21.1.

22.      Termination.

         22.1 Right to Terminate. Either Party may terminate this Agreement upon
         notice to the other if:

         (a)      Material Breach. The other Party breaches a material
                  obligation under this Agreement and such breach continues
                  without cure for a period of thirty (30) days after notice or,
                  if the breach is not one which is capable of being cured
                  within thirty (30) days and the breaching Party has commenced
                  to cure the breach within such time and continues to do so
                  diligently and in good faith, then the breaching Party shall
                  be granted an extension for a reasonable period of time at the
                  discretion of the non-breaching Party.

         (b)      Change of Control. An entity that does not currently control
                  Company or Motorola, as the case may be, acquires either
                  direct or indirect control of the other Party (Company or
                  Motorola, as the case may be) and such Change of Control
                  materially and adversely affects the rights of the terminating
                  party. For these purposes, Change of Control shall mean the
                  possession of the power, directly or indirectly, to direct or
                  cause the direction of management or policies of the Party,
                  whether through the ownership of more than fifty percent (50%)
                  of the then outstanding shares or other equity rights of the
                  Party or by contract or agency or such similar arrangement. In
                  such event, if a Party terminates because of a Change in
                  Control of the other Party, the Parties shall cooperate to
                  conduct an orderly termination of the Agreement. Motorola
                  acknowledges that Company is expecting to conduct an initial
                  public offering in the near future. Motorola agrees that this
                  event alone will not give rise to a Change of Control event
                  that will permit Motorola to terminate this Agreement under
                  this Section 22(b)

         (c)      Insolvency or Cessation of Business. The other Party ceases to
                  conduct business in the normal course in a manner that
                  materially adversely affects the ability of the Party to meet
                  its obligations under this Agreement, becomes insolvent,
                  enters into a general suspension of payments, moratorium,
                  reorganization or bankruptcy, makes a general assignment for
                  the benefit of creditors, admits in writing its inability to
                  pay debts as they mature, suffers or permits the appointment
                  of a receiver for substantially all of its business or assets,
                  or avails itself of or becomes subject to any other judicial
                  or administrative proceeding that relates to insolvency or
                  protection of creditors' rights.

         22.2 Rights and Obligations at Termination. Upon expiration or
         termination of this Agreement for any reason:

                                      -22-
<PAGE>

         (a)      Cease and Destroy. Each Party will promptly cease using and
                  destroy and certify such destruction, or return to the other
                  Party, all items that contain any Confidential Information (as
                  defined herein) of the other Party, except Motorola may retain
                  one copy of Confidential Information for the sole and express
                  purpose of supporting then-existing Customers in connection
                  with their use of products supplied by Company hereunder.

         (b)      Sale of Inventory. Motorola may sell any of its then existing
                  inventory of Products originally purchased from Company.
                  However, Company shall have no warranty and support
                  obligations for such product under Sections 22.2(d) and (g) if
                  this Agreement is terminated because of Motorola's material
                  default pursuant to Section 22.1(a).

         (c)      Right to Use. Unless otherwise provided for herein, Motorola
                  and Customers shall continue to have the right to use Software
                  in Object Code form associated with the Products sold under
                  this Agreement, but subject to the limitations of this
                  Agreement.

         (d)      Spares. Upon termination of the initial term or any renewal of
                  this Agreement, or upon termination for any reason other than
                  Company's total cessation of business, Company agrees to use
                  all commercially-reasonable efforts, subject to vendor
                  availability, to offer for sale to Motorola, in accordance
                  with the provisions set forth herein, functionally equivalent
                  Spares for a period no less than ten (10) years after the
                  expiration or termination of this Agreement. In the event
                  Company is unable to supply such Spares or is unable, after
                  notice and a reasonable period of time, to obtain another
                  source of supply for Motorola, then Company shall provide
                  Motorola and its designated third party manufacturers of such
                  Spares with a royalty-free, non-exclusive license to use
                  intellectual property so that Motorola and such manufacturers
                  will have sufficient information and right to manufacture or
                  to obtain functionally equivalent Spares from other sources,
                  but solely for purposes of supplying Spares for Products sold
                  by Company under this Agreement. Company shall be obligated to
                  provide support services for Hardware, as set forth in Exhibit
                  D, attached hereto, for a period of ten (10) years after the
                  date of termination, and to provide support services for
                  Software, as set forth in Exhibit D, attached hereto, for a
                  period of two (2) years after the date of termination, unless
                  such termination is due to a material breach by Motorola,
                  pursuant to Section 22.1(a). In the event of a Company
                  bankruptcy, for purposes of this Agreement, the Parties
                  acknowledge that Motorola shall be entitled to the full
                  protection provided to licensees of intellectual property
                  rights specified in 11 U.S.C. 365.

         (e)      Outstanding Sums. Company shall invoice Motorola for any
                  outstanding sums which may be owing from any Order as detailed
                  in Exhibit "A. In the event that Motorola terminates for
                  material breach as set forth herein, Motorola reserves the
                  right to offset any damages it incurs against any sums that
                  Motorola owes to Company.

         (f)      Source Code. In the event of a termination due to the
                  conditions set forth in Subsection 22.1(c) above, Company
                  shall provide to Motorola Source Code in accordance with the
                  terms of any escrow agreement entered into pursuant to Section
                  19.

         (g)      Continuation of Services. Upon termination at the end of the
                  initial term or any renewal thereof, unless termination is due
                  to a material breach by Motorola, pursuant to Section 22.1(a)
                  Company will provide warranty remedy, support services, of the
                  type required hereby, until the end of the last applicable
                  warranty period or term of support or maintenance agreement.

23.      Term and Renewal.

         This Agreement shall commence as of the Agreement Date and shall be for
         an initial term of two (2) years, and may be renewed by the Parties for
         successive terms of one-year each, provided that each Party executes a
         written consent as to each one year renewal period sixty (60) days in
         advance of the expiration date of the previous term.

         24.1 Product Liability. Company represents and warrants that the
         Products shall be produced and delivered in accordance in all material
         respects with all applicable laws, rules and regulations governing
         product safety of those jurisdictions from which Company or Motorola
         (with the active cooperation of Company) has obtained or is in the

         brought against Motorola, its directors, officers, agents or Customers
         for personal injury, death, or physical damage to tangible property
         based upon a claim that the Products, or any aspect of the Products,
         breached the representation of Section 24.1, have caused death or
         personal injury, are defective in any way, or were negligently designed
         or manufactured or fail to comply with any product safety laws. Company
         further, subject to the limitations of Section 21.1, agrees to
         indemnify and hold harmless Motorola, its directors, officers, agents
         and Customers against any and all expenses, losses and damages,
         including court costs and attorney's fees, resulting from any such suit
         or proceeding, including any settlement. Motorola may be represented by
         and actively participate through its own counsel in any such suit or
         proceeding if it so desires, and the cost of such representation shall
         be paid by Motorola.

25.      Security.

         Each Party agrees that, when employees or agents of the visiting Party
         are on the premises of the host Party, they will at all times comply
         with all security regulations in effect and of which the Party has been
         apprised. The visiting Party further agrees to abide at all times with
         off premises security regulation when the visiting Party has
         Confidential Information of the host Party. Motorola and Company
         specifically agree not to disclose to any third party any information,
         systems, equipment, ideas, processes or methods of operation observed
         at either Party's facilities, all of which shall be deemed Confidential
         Information as defined herein.

         27.2 When Effective. Notices shall be effective upon the date of
         receipt of delivery or at such time as delivery is refused by addressee
         upon presentation.

28.      Force Majeure.

         28.1 Definition. Neither Party shall be liable for delays in delivery
         or performance when caused by any of the following which include but
         are not limited to, acts or events which are beyond the actual control
         of the delayed Party, including but not limited to the following: (i)
         acts of God, (ii) acts of the public enemy, (iii) acts or failure to
         act by the other Party, (iv) acts of civil or military authority, (v)
         governmental priorities, strikes or other labor disturbances, (vi)
         hurricanes, (vii) earthquakes, (viii) fires, (ix) floods, (x)
         epidemics, (xi) embargoes, (xii) war, (xiii) riots, and (xv) failures
         of common carriers.

         28.2 Extension. In the event of any such delay the date of delivery or
         of performance shall be extended for a period equal to the effect of
         time lost by reason of the delay.

         28.3 Right to Terminate. Notwithstanding the foregoing, in the event
         that such Force Majeure causes Company to be delayed in its delivery or
         performance for more than seventy-five (75) days, Motorola shall have
         the right to terminate this Agreement with no liability whatsoever.

         28.4 Notice. A party claiming delay in delivery or performance, due to
         an act of force majeure as set forth herein, shall send written notice
         thereof and a statement of particulars to the other party, prior to or
         at the time performance would have been required by the non-performing
         party.

29.      Governing Law and Dispute Resolution.

         29.1 Governing Law. The validity, performance, and all matters relating
         to the effect of this Agreement and any amendment hereto shall be
         governed by the laws of the State of Illinois, U.S.A., which shall be
         applied without regard to the U.N. Convention on International
         Contracts for the Sale of Goods.

         29.2 Escalation. Motorola and Company agree to attempt to settle any
         claim or controversy arising out of this Agreement through consultation
         and negotiation in good faith and spirit of mutual cooperation. Any
         dispute between the Parties relating to this Agreement will first be
         submitted in writing to a panel of two senior executives of Company and
         Motorola, who will promptly meet and confer in an effort to resolve
         such dispute. Each Party's executive will be identified by notice to
         the other Party, and may be changed at any time thereafter by notice to
         the other. Any agreed decisions of the executives will be final and
         binding on the Parties. In the event the executives are unable to
         resolve any dispute within thirty days after submission to

                                      -25-
<PAGE>

         them, either Party may then refer such dispute to mediation in
         accordance with Subsection 29.3. Notwithstanding the foregoing, any
         disputes with respect to intellectual property rights shall be
         submitted to the courts and not be subject to the provisions of this
         Section 29.2 or Subsection 29.3.

         29.3 Alternate Dispute Resolution ("ADR"). If those attempts fail, then
         the dispute will be mediated by a mutually acceptable mediator to be
         chosen by Motorola and Company within forty-five (45) days after
         written notice by either Party demanding mediation. Such mediation
         shall be conducted in a location to be agreed upon by the parties.
         Neither Party may unreasonably withhold consent to the selection of a
         mediator or location, and Motorola and Company will share the costs of
         the mediator equally. Each Party shall pay its own attorneys' fees. By
         mutual agreement, however, Motorola and Company may postpone mediation
         until each has completed some specified but limited discovery regarding
         the dispute. The Parties may also agree to replace mediation with some
         other form of alternate dispute resolution, such as neutral
         fact-finding or a mini-trial.

         29.4 Submittal to Courts. Any dispute which cannot be resolved between
         the Parties through negotiation, mediation or other form of ADR within
         four (4) months of the date of the initial demand for ADR by one of the
         Parties shall then be submitted to a court of competent jurisdiction.
         The use of any ADR procedures will not be construed under the doctrines
         of laches, waiver or estoppel to affect adversely the rights of either
         Party. Nothing in this Section will prevent either Party from resorting
         to judicial proceedings if (a) good faith efforts to resolve the
         dispute under these procedures have been unsuccessful, or (b) interim
         relief from a court is necessary to prevent serious and irreparable
         injury to that Party or to others.

30.      Subcontracting.

         Company shall not, without the prior written consent of Motorola,
         subcontract any portion of the work covered by this Agreement except
         for the purchase of standard commercial supplies or raw materials
         incidental to the work to be performed.

31.      Assignment.

         Neither this Agreement nor any right under this Agreement may be
         transferred, assigned or delegated by either Party without the prior
         written consent of the other Party. Any attempted assignment,
         delegation or transfer shall be void.

32.      Independent Contractors.

         Company shall perform activities under this Agreement only as an
         independent contractor and nothing contained herein shall be construed
         to be inconsistent with this relationship or status. Under no
         circumstances shall any personnel of Company be considered to be an
         employee or agent of Motorola. Nothing in this Agreement shall be
         interpreted as granting either Party the right or authority to make
         commitments of any kind for the other, implied or otherwise, without
         prior review and written agreement. This Agreement shall not
         constitute, create, or in any way be interpreted as a joint venture,
         partnership or formal business organization of any kind.

33.      Authority.

         Each Party hereto represents and warrants that (i) it has obtained all
         necessary approvals, consents and authorizations of third parties and
         governmental authorities, if applicable, to enter into this Agreement
         and to perform and carry out its obligations under this Agreement, (ii)
         the persons executing this Agreement on its behalf have express
         authority to do so, and, in so doing, to bind the Party thereto; (iii)
         the execution, delivery, and performance of this Agreement does not
         violate any provision of any bylaw, charter, regulation, or any other
         governing authority of the Party; and (iv) the execution, delivery and
         performance of this Agreement has been duly


                                      -26-
<PAGE>

         authorized by all necessary partnership or corporate action and this
         Agreement is a valid and binding obligation of such Party, enforceable
         in accordance with its terms.

34.      No Right to Audit.

         Nothing contained herein shall be deemed to grant Company or any third
         party, by implication, estoppel or otherwise, any right to inspect or
         examine any of Motorola's data, documents, instruments, records,
         software, systems, premises or plants related to or in any way
         connected with the Products. Motorola shall have no duty to disclose
         any financial statements, balance sheets, or any other business records
         to Company, Company's representatives or any third party which may
         request same. By way of example, and not limitation, Motorola has no
         duty to disclose the existence or location of any Customer who has
         purchased Products.

35.      Cumulative Remedies.

         Except as otherwise provided herein, if Company breaches this
         Agreement, Motorola shall have the right to assert all legal and
         equitable remedies available.

36.      Severability and Survivability.

         In the event any one or more of the provisions of this Agreement is
         held to be unenforceable under applicable law, (i) such
         unenforceability shall not affect any other provision of this
         Agreement; (ii) this Agreement shall be construed as if said
         unenforceable provision had not been contained herein; and (iii) the
         Parties shall negotiate in good faith to replace the unenforceable
         provision by such as has the effect nearest to that of the provision
         being replaced.

         The Parties agree that where the context of any provision indicates an
         intent that it shall survive the term of this Agreement then it shall
         survive. For the avoidance of doubt, the following sections shall
         survive: 12 - Warranty; 19 - Source Code Escrow; 20 - Confidential
         Information; 21- Limitation of Liability and Indemnification; 22.2
         Rights and Obligations at Termination; 29- Governing Law and Dispute
         Resolution.

37.      Publicity.

         Neither party shall issue a press release or make any similar public
         announcement regarding the transactions contemplated by this Agreement
         without the other party's prior written consent to the specific
         language and intended distribution of such press release or
         announcement.

38.      Entire Agreement.

         This Agreement and Exhibits hereto constitute the entire understanding
         between the Parties concerning the subject matter hereof and supersede
         all prior discussions, agreements and representations, whether oral or
         written and whether or not executed by Motorola and Company. In case of
         inconsistencies between the terms of this Agreement and the Exhibits,
         this Agreement shall govern and supercede the Exhibits. Orders issued
         pursuant to this Agreement shall be deemed to be governed by the terms
         of this Agreement, and in case of inconsistencies between the terms of
         this Agreement and such Orders, this Agreement shall supercede, whether

PRODUCT BRAND MARK SPECIFICATIONS:

The Motorola brand mark applied to products is different from the standard
Motorola brand mark. This mark is to be applied to product only.  The mark to be
used on product is a modified horizontal Motorola signature. It differs from the
standard signature in that the ratio of the diameter of the emsignia logo to the
height of the letters in the word Motorola is 2.25:1, and the space between the
ring of the emsignia and the left edge of the M of the word Motorola is .75x the
height of the letters of the word Motorola. In addition, the weight of the ring
of the emsignia has been increased by a factor of two. This is the only
acceptable Motorola brand mark to be used on product.

Electronic copies of this mark are available from CSS Industrial Design Group,
Libertyville, Illinois, USA, fax number 1-847-523-8512.

In the standard horizontal signature, the emsignia diameter to letter height
ratio is 3:1, and the space between the emsignia and the word Motorola is equal
to the height of the letters. The standard horizontal signature is used on all
non-product applications.
<PAGE>

PLACEMENT OF THE BRAND MARK:

These policies have been established to treat the Motorola mega-brand as the
dominant identity element on all consumer products. In that context, the
Motorola brand mark should always be placed in a position of prominence on the
front or primary surface of the product. It should be the largest single graphic
element presented, with as much "free space" around it as the product dimensions
will allow.

If the product incorporates a "hinged" component that acts as a cover or partial
covering to the primary functional surface, the Motorola brand mark should
appear on both surfaces, so that the Identity is displayed in both the "open"
and "closed" configuration.

BRAND MARK SIZE:

The brand mark should be reproduced as large as possible but at a size that is
suitable and compatible with the overall size and dimensions of the product.
Every attempt should be made to feature the Motorola mark at a length larger
than one inch (2.54 cm), as measured from the left outside edge of the ring of
the emsignia logo, to the right extension of the A of the word MOTOROLA. In any
case, the length of the mark can be no less than .75 of an inch (1.90 cm) as
measured from the left outside edge of the ring of the emsignia logo to the
right extension of the A of the word MOTOROLA.


          Length of 1 inch (2.54 cm) (shown at twice the actual size):

are hereby acknowledged, Company, Motorola and Escrow Agent hereby agree as
follows:

1.   DEPOSITS

     (a)  Within five (5) days after the date hereof, Company shall deposit with
          Escrow Agent, the Source Code described on Exhibit A (Software),
          attached hereto and made a part hereof, which Exhibit lists software

          for each delivery of Source Code.

     (c)  The Source Code held by the Escrow Agent shall remain the exclusive
          property of Company.  The Escrow Agent shall not use the Source Code
          or disclose the same to any third party except as specifically
          provided for herein and nothing in this Escrow Agreement shall be
          construed as a conveyance by Company of all or any of its rights,
          title or interest in the Source Code to the Escrow Agent, except as
          specifically provided herein.

     (d)  The Escrow Agent will hold the Source Code in safekeeping for Company
          and Motorola, pursuant to the terms and conditions set forth herein,
          and act as custodian thereof, at its offices herein above indicated,
          unless and until the Escrow Agent receives notice pursuant to the
          terms of this Escrow Agreement that the Escrow Agent is to deliver the
          Source Code to Motorola or Company, in which case the Escrow Agent
          shall deliver the Source Code to the party identified therein,
          subject, however, to the provisions of this Escrow Agreement. The
          Source Code shall be retained by Escrow Agent at Escrow Agent's
          vaulting site at all times, under the express control of an officer
          designated by it, whose identity shall be made known to Motorola and
          Company promptly upon designation.

     (e)  During all the following procedures, the Parties agree that Motorola
          will not have access to the source code escrow unless the source code
          has been released pursuant to Section Three of this Escrow Agreement.

          (i)   When DSI receives the Deposit Materials and the Exhibit B, DSI
                will conduct a deposit inspection by visually matching the
                labeling of the tangible media containing the Deposit Materials
                to the item descriptions and quantity listed on the Exhibit B.
                In addition to the deposit inspection, Motorola may elect to
                cause a verification of the Deposit Materials pursuant to DSI's
                standard verification procedures.

          (ii)  At completion of the deposit inspection, if DSI determines that
                the labeling of the tangible media matches the item descriptions
                and quantity on Exhibit B, DSI will date and sign the Exhibit B
                and mail a copy thereof to Motorola and Company. If DSI
                determines that the labeling does not match the item
                descriptions or quantity on the Exhibit B, DSI will (a) note the
                discrepancies in writing on the Exhibit B; (b) date and sign the
                Exhibit B with the exceptions noted; and (c) mail a
<PAGE>

                copy of the Exhibit B to Motorola and Company. DSI's acceptance
                of the deposit occurs upon the signing of the Exhibit B by DSI.
                Delivery of the signed Exhibit B to Motorola is Motorola's
                notice that the Deposit Materials have been received and
                accepted by DSI.

          (iii) The Deposit Materials may be removed and/or exchanged only on
                written instructions signed by Motorola and Company, or as
                otherwise provided in this Agreement.

2.  REPRESENTATION OF COMPANY TO MOTOROLA

     (a)  Company states that:

          (i)  the Source Code described in Exhibit A and Exhibit B constitutes
               the most recent programs (in Source Code); and

          (ii) the Source Code delivered to the Escrow Agent will be reviewed
               and  inspected by Escrow Agent and supplemented by Company
               preferably within sixty days of each release of a new version but
               in no event less than annually, on the anniversary date of this
               Agreement, with all revisions, corrections, enhancements or other
               changes made during such prior year, to ensure its current
               status, and Company shall give written notice to Motorola of all
               such supplements/deposits as they are made. In the event that
               Motorola has reasonable grounds for insecurity with respect to
               the performance of Company's support obligations under this
               Agreement, Motorola shall send Company a written request for
               assurance that Company has deposited any and all releases of the
               source code into escrow.   Escrow Agent shall make the Source
               Code available to Motorola for such inspection.

     (b)  Company shall be responsible for its own costs associated with the
          initial deposit of Source Code (Exhibits A and B) and update of
          escrowed materials with the Escrow Agent.

3.  NOTICE OF DEFAULT

     (a)  Company shall be deemed to be in default of its responsibilities to
          Motorola if:

          (i)  Company becomes the subject of any proceeding under applicable
               bankruptcy, receivership, insolvency or similar laws which are
               not, in the case of proceedings brought against Company,
               dismissed within thirty  (30) days of filing, and after a cure
               period not to exceed  thirty  (30) days, such event prevents
               Company in any material respect from delivering in accordance
               with the terms of the Agreement and on a timely basis, previously
               ordered Products incorporating the then current version; or

          (ii) Company fails to meet in   all   material respects, substantially
               all of  its material support obligations under the Agreement
               within  thirty  (30) days of Motorola's written notice of default
               given in accordance with the Agreement.

     (b)  Motorola shall not be entitled to treat an event under (ii) as a
          default, and give a Notice of Default, if Motorola is then in material
          default under the Agreement.  An event of default under (ii) shall not
          be deemed to have occurred if a successor to the Company is
          undertaking in material respects the support required by the
          Agreement.
<PAGE>

     (c)  Motorola shall give written notice (the "Notice of Default") to the
          Escrow Agent of any default by Company of the type listed at Section
          3(a)  above and send a copy thereof to Company.  The Notice of Default
          shall be labeled "Notice of Default";  identify the Agreement and this
          Escrow Agreement; specify the nature of the default; and demand that
          the Escrow Agent deliver the Source Code to Motorola, unless, within
          ten (10) business days of its receipt of Notice of Default, the Escrow
          Agent receives written notice from Company, showing a copy to
          Motorola, that Company has sought and obtained a preliminary
          injunction or temporary restraining order against the transfer of the
          Source Code to Motorola.  Such written notice must include a copy of
          the order issued by the court granting the relief described above.  If
          Company succeeds in obtaining a preliminary injunction or temporary
          restraining order, the Escrow Agent will retain the Source Code
          pending final resolution in a court of law or alternate dispute
          resolution proceeding, as appropriate and subject to Section Nine of
          this Escrow Agreement.  If Company does not prevail in such
          proceeding, the Escrow Agent will immediately and without further
          delay, transfer the Source Code directly to Motorola.  This provision
          is subject to DSI's standard escrow fees, which are attached hereto as
          Exhibit D, and Section Nine of this Escrow Agreement.

4.   USE OF SOURCE CODE

     Upon delivery of the Source Code to Motorola, Motorola agrees that its use
     (and modification, as required) of the Source Code shall be strictly
     limited to the support, maintenance, and use of the Products as previously
     supplied by the Company under the Agreement.  Without limiting the
     foregoing, Motorola shall not duplicate, sell or license the Source Code to
     others or market the Source Code in any manner.

5.   DUTIES AND LIMITED OBLIGATIONS OF ESCROW AGENT

     (a)  Escrow Agent shall be under no obligation or responsibility to either
          Company or Motorola to determine the existence, relevance,
          completeness, accuracy or other aspects of the Source Code or any
          portions thereof deposited from time to time by Company.  Escrow Agent
          shall have no obligation or responsibility to determine whether what
          is deposited or accepted by it for deposit is or is not Source Code as
          defined herein.  Furthermore, this Escrow Agreement shall constitute
          notice to any third person or entity who may acquire a right of access
          to the Source Code that Escrow Agent's duty is limited as set forth
          herein and that Escrow Agent is not liable to any such third person or
          entity.  Company and Motorola further agree that Escrow Agent shall
          not be liable for any forgeries or impersonations concerning any
          documents of record or other documents it is handling in its capacity
          as Escrow Agent.

     (b)  Escrow Agent agrees to prevent any unauthorized person or persons from
          gaining access to the Source Code, except as specifically provided by
          this Escrow Agreement.

     (c)  Escrow Agent agrees not to use the Source Code for any purpose except
          as provided hereunder.

     (d)  Company and Motorola further agree that if they disagree on any matter
          connected with this Escrow Agreement, Escrow Agent will not be
          required to settle the matter.  If Escrow Agent is made a party to
          legal proceedings, Escrow Agent will be entitled to such reasonable
          compensation for services, costs and attorneys' fees as may be
          awarded, which compensation shall be paid by the non-prevailing party.
<PAGE>

6.   LIMITATION OF LIABILITY

     (a)  The Escrow Agent's liability for damage to or loss of materials stored
          on magnetic media shall be limited to the physical replacement cost of
          such media.  The Escrow Agent reserves the right to provide
          replacement of media rather than reimbursement.  The Escrow Agent will
          not be liable for incidental or consequential damages.  This
          limitation will apply regardless of the form of action, whether in
          contract or tort, including negligence.  Any action against Escrow
          Agent must be brought within twelve (12) months after the cause of
          action accrues.

     (b)  The Escrow Agent shall not be liable for any damages due to causes
          beyond its reasonable control, including but not limited to, acts of
          God.

7.   INDEMNIFICATION

     Motorola  and Company agree to indemnify and defend Escrow Agent for and
     hold it harmless against, any claim, action, damage, loss, cost or expense
     incurred or suffered in connection with, including but not limited to
     attorney's fees and costs, as a result of, service as Escrow Agent under
     this Escrow Agreement, except for any costs or expenses suffered as a
     result of Escrow Agent's sole adjudged willful misconduct or negligence.

     UNLESS SPECIFICALLY SET FORTH HEREIN, IN NO EVENT SHALL EITHER MOTOROLA,
     COMPANY OR ESCROW AGENT, WHETHER AS A RESULT OF BREACH OF CONTRACT, TORT
     (INCLUDING NEGLIGENCE) OR OTHERWISE, HAVE ANY LIABILITY TO  EACH OTHER
     FOR ANY INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES.IN NO EVENT
     SHALL THIS SECTION ALTER COMPANY'S OR MOTOROLA'S OBLIGATIONS TO INDEMNIFY,
     DEFEND AND HOLD HARMLESS ESCROW AGENT AS STATED ABOVE.

8.   CONFIDENTIALITY

     Escrow Agent and its employees agree to hold confidential the Source Code
     and to exercise the same degree of care that a reasonable and careful
     company would exercise with similar records of its own.

9.   PAYMENT TO ESCROW AGENT

     As payment for its services hereunder, the Escrow Agent shall receive
     annual charges as set forth in Exhibit D which is attached hereto and
     incorporated herein. .  The first such annual charges will be paid by

     all parties hereto.  Each year thereafter, Motorola will pay the
     appropriate charges on or before the anniversary of the effective date of
     this Escrow Agreement.  The annual fee may be adjusted by the Escrow Agent
     on an annual basis  no more than  (10%) percent per annum.  The Escrow
     Agent shall notify Company of any such adjustment to the annual fee at
     least thirty (30) days prior to the annual fee due date.

     based upon an event of the nature described in Section 3(a)(i) and/or (ii)

     instructions, Escrow Agent may, at its sole discretion, destroy the Deposit

<PAGE>

     are enrolled to this account, Company may obtain the return of the Source
     Code by furnishing written notice of the termination, agreed to in writing
     by an authorized signature of Motorola.

     this Escrow Agreement shall terminate on the delivery of the Source Code to
     either party in accordance with the terms of this Escrow Agreement. Escrow
     Agent shall not retain any copies of the Source Code on termination.  This
     Escrow Agreement may also be terminated by:   i) Escrow Agent for non-

     Motorola and Company), has been appointed, and a procedure for the orderly
     transfer of the Source Code from the Escrow Agent to the successor escrow
     agent, has been formalized and agreed to by all parties.

35.  EFFECT OF VALUE ADDED TAX, CUSTOMS OR OTHER DUTIES

duty affecting the equipment or material or any part of the equipment or
material is increased, decreased, imposed or abolished, or any alteration is
made by the Government of Ireland in the practice of assessing the value of
goods for the purposes of Customs duty, and the amount of duty payable on the
equipment or material or any part of the material is thereby increased or
decreased, the amount to which the Contractor shall be entitled under the
Contract shall be increased or decreased, as the case may require, by a sum
equal to the difference between the amount of duty which would have been payable

paid by the Contractor on the equipment or material delivered by him under the
Contract.

If on the expiration of the Validity Period, the rate of Value Added Tax payable
by the Contractor on the monies received from the Director under the Contract is
increased or decreased, the amount to which the Contractor shall be entitled
under the Contract shall be increased or decreased, as the case may require, so
that the amount less value added tax at the revised rate equals the amount less
value added tax at the rate obtaining on the expiration of the Validity Period.

The Contractor shall, whenever so required by the Director, produce for

If the whole or the major portion of the work shall be suspended for a period
exceeding two days by order of  the Director, or by order of any local
authority, body or person in whose order the Director is constrained to
acquiesce, provided that such suspension is not due to any default of the
Contractor and provided also that such suspension shall necessitate the
cessation of work of all or the greater part of the Contractor's workmen engaged
upon the work, then the Director shall pay to the Contractor such reasonable
expenses incident to the suspension of work as the Director in his sole
discretion may determine as proper to be allowed.  Such allowance of expenses
shall be made only in respect of suspension authorised in writing by the
Director or the Supervising Officer (such authority not being unreasonably
withheld in cases not provided for in Clause 36) and the Contractor shall on his
part afford the Director all necessary facilities to enable him to determine the

          cost of the item concerned, excepting only where Eircom agrees and
          accepts that satisfactory repair of the item can be achieved at lesser
          cost in which case compensation shall be equivalent to the cost of
          repairs plus any ancillary cost incurred.

          Eircom reserves the right to withhold payment of such a sum as in the
          opinion of Eircom is sufficient to cover any payments or liabilities
          that may become due as a result of the execution of the Contract. Any
          payment so withheld may be used by Eircom to discharge any such
          liability to any third party without the prior agreement of the
          Contractor.

          liable to pay a penalty or penalties to the Office of the Director of
          Telecommunications Regulation (ODTR) in respect of such failure or
          delay, the Contractor shall indemnify and keep Eircom effectively
          indemnified against the payment of such penalty, in so far as the

          intention of the parties hereby declared being that the sum payable
          under sub-clause (1) or sub-clause (2) of this Clause shall be paid as

          clause (1) or  sub-clause (2) of this Clause a sum equal to the excess
          (if any) of the expenses incurred by eircom in or about such execution
          over and above the expense that would have been incurred by the due
          completion of the work by the Contractor.

               Contractor's assets; or

          (d)  a petition for the appointment of a receiver or an examiner is

          (a)  Eircom shall, subject to sub-clause 41.3 (b) below, pay the
               Contractor such amounts as may be necessary to cover its
               reasonable costs and outstanding and unavoidable commitments
               necessarily and solely incurred in properly performing the

               consequent upon such termination.

               COMPLIANT.

     41.4 Where notice of termination is given due to insufficient progress, the
          Contractor may issue a counter notice in writing within 3 working days
          giving its proposals for completion of the work within the time
          allowed in the Contract. Eircom shall, within 5 working days, either

          notice is to stand.

          arbitration shall be conducted by some person appointed on the
          application of either party by the President of the Institution of
          Engineers in Ireland. Any reference to arbitration shall be conducted
          in accordance with the Institution of Engineers in Ireland arbitration
          procedures or any amendment or modification thereof being in force at
          the time of appointment of an arbitrator and shall be deemed to be a
          submission to arbitration within the meaning of the Arbitration Act,

COMPLIANT - ACL AGREES TO PROVIDE A BOND OF EURO'S 4 MILLION.

45.  FORCE MAJEURE

Such extension of time as may appear to eircom to be reasonable shall be allowed

circumstances beyond the reasonable control of either party.

If either party is prevented or delayed from or in performing any of their
obligations under the Contract by force majeure in spite of all reasonable
endeavours to continue to perform  their obligations under the Contract then it
must notify the other party of the circumstances constituting the force majeure
and of the obligations, the performance of which, are thereby delayed or
prevented.  The party giving notice shall thereupon be excused its performance
or punctual performance as the case may be of such obligation for so long as the
circumstances of prevention or delay may continue. Should force majeure
thereafter circumstances continue for a continuous period of 120 days then
either party may at any time and provided such performance or punctual
performance is still excused by 21 days notice in writing to the other terminate
the Contract.  In the event of such termination then the provisions of Clause 41
hereof shall be invoked.

                       AIRSPAN COMMUNICATIONS CORPORATION
                  1998 STOCK OPTION AND RESTRICTED STOCK PLAN

            (as amended by the board and shareholders May 24, 2000)

     Section 1.  Purpose.  The purpose of the Airspan Communications Corporation
                 -------
1998 Stock Option and Restricted Stock Plan (the "Plan") is to promote the
interests of Airspan Communications Corporation, a Delaware corporation (the
"Company"), and any Subsidiary thereof and the interests of the Company's
stockholders by providing an opportunity to selected employees, officers and
directors of the Company or any Subsidiary thereof as of the date of the
adoption of the Plan or at any time thereafter to purchase Common Stock of the
Company.  By encouraging such stock ownership, the Company seeks to attract,
retain and motivate such employees and persons and to encourage such employees
and persons to devote their best efforts to the business and financial success
of the Company. It is intended that this purpose will be effected by the
granting of "non-qualified stock options" and/or "incentive stock options" to
acquire the Common Stock of the Company and/or by the granting of Common Stock
or rights to purchase the Common Stock of the Company on a "restricted stock"
basis. Under the Plan, the Committee shall have the authority (in its sole
discretion) to grant "incentive stock options" within the meaning of Section
422(b) of the Code, "non-qualified stock options" as described in Treasury
Regulation Section 1.83--7 or any successor regulation thereto, or "restricted
stock" awards.

     Section 2.  Definitions.  For purposes of the Plan, the following terms
                 -----------
used herein shall have the following meanings, unless a different meaning is
clearly required by the context.

     2.1.  "Award" shall mean an award of Common Stock or the right to purchase
            -----
Common Stock granted under the provisions of Section 7 of the Plan.

     2.2.  "Board of Directors" shall mean the Board of Directors of the
            ------------------
Company.

     2.3.  "Code" shall mean the Internal Revenue Code of 1986, as amended.
            ----

     2.4.  "Committee" shall mean the committee of the Board of Directors
            ---------
referred to in Section 5 hereof.

     2.5.  "Common Stock" shall mean the Common Stock, $.01 par value, of the
            ------------
Company.

     2.6.  "Employee" shall mean (i) with respect to an ISO, any person,
            --------
including an officer or director of the Company, who, at the time an ISO is
granted to such person hereunder, is employed on a full-time basis by the
Company or any Subsidiary of the Company, and (ii) with respect to a Non-
Qualified Option and/or an Award, any person employed by, or performing services
for, the Company or any Subsidiary of the Company, including, without
limitation, directors and officers.
<PAGE>

     2.7.  "ISO" shall mean an Option granted to a Participant pursuant to the
            ---
Plan that constitutes and shall be treated as an "incentive stock option" as
defined in Section 422(b) of the Code.

     2.8.  "Non-Qualified Option" shall mean an Option granted to a Participant
            --------------------
pursuant to the Plan that is intended to be, and qualifies as, a "non--qualified
stock option" as described in Treasury Regulation Section 1.83--7 or any
successor regulation thereto and that shall not constitute nor be treated as an
ISO.

     2.9.  "Option" shall mean any ISO or Non--Qualified Option granted to an
            ------
Employee pursuant to the Plan.

     2.10.  "Participant" shall mean any Employee to whom an Award and/or an
             -----------
Option is granted under the Plan.

     2.11.  "Parent of the Company" shall have the meaning set forth in Section
             ---------------------
424(e) of the Code.

     2.12.  "Subsidiary of the Company" shall have the meaning set forth in
             -------------------------
Section 424(f) of the Code.

     Section 3.  Eligibility.  Awards and/or Options may be granted to any
                 -----------
Employee. The Committee shall have the sole authority to select the persons to
whom Awards and/or Options are to be granted hereunder, and to determine whether
a person is to be granted a Non-Qualified Option, an ISO or an Award or any
combination thereof. No person shall have any right to participate in the Plan.
Any person selected by the Committee for participation during any one period
will not by virtue of such participation have the right to be selected as a
Participant for any other period.  On and after the time that the Company
becomes subject to Code Section 162(m), no Participant shall be granted Options
and/or Awards under the Plan with respect to more than 1,000,000 shares of
Common Stock in any calendar year (subject to adjustment as provided in Section
8 hereof).

     Section 4.  Common Stock Subject to the Plan.

     4.1.   Number of Shares.  The total number of shares of Common Stock for

number of ISOs that may be granted hereunder) shall not exceed in the aggregate
four million five hundred ninety-one thousand six hundred sixty-six (4,591,666)
shares of Common Stock (subject to adjustment as provided in Section 8 hereof).

     4.2.   Reissuance.  The shares of Common Stock that may be subject to
            ----------
Options and/or Awards granted under the Plan may be either authorized and
unissued shares or shares reacquired at any time and now or hereafter held as
treasury stock as the Board of Directors may determine. In the event that any
outstanding Option expires or is terminated for any reason, the shares allocable
to the unexercised portion of such Option may again be subject to an Option
and/or Award granted under the Plan. If any shares of Common Stock acquired
pursuant to an Award or the exercise of an Option shall be forfeited or
repurchased by the Company, then such shares shall again become available for
issuance pursuant to the Plan.

                                       2
<PAGE>

     4.3. Special ISO Limitations.
          -----------------------

     (a)  To the extent that the aggregate fair market value (determined as of
the date an ISO is granted) of the shares of Common Stock with respect to which
ISOs are exercisable for the first time by an Employee during any calendar year
(under all Incentive Stock Option Plans of the Company or any Parent or
Subsidiary of the Company) exceeds $100,000, then the excess thereof shall be
treated as a Non-Qualified Option and not as an ISO.  This rule shall be applied
by taking Options into account in the order in which they are granted.

     (b)  No ISO shall be granted to an Employee who, at the time the ISO is
granted, owns (actually or constructively under the provisions of Section 424(d)
of the Code) stock possessing more than 10% of the total combined voting power
of all classes of stock of the Company or any Parent or Subsidiary of the
Company, unless the option price is at least 110% of the fair market value
(determined as of the time the ISO is granted) of the shares of Common Stock
subject to the ISO and the ISO by its terms is not exercisable more than five
years from the date it is granted.

     4.4. Limitations Not Applicable to Non-Qualified Options or Awards.
          -------------------------------------------------------------
Notwithstanding any other provision of the Plan, the provisions of Sections
4.3(a) and (b) shall not apply, nor shall be construed to apply, to any Non-
Qualified Option or Award granted under the Plan.

     Section 5.  Administration of the Plan.
                 --------------------------

     5.1. Administration.  The Plan shall be administered by a committee of the
          --------------
Board of Directors (the "Committee") established by the Board of Directors and
consisting of no less than two persons.  From and after the time that any equity
securities of the Company become registered or required to be registered under
Section 12 of the Securities Exchange Act of 1934 ("Exchange Act"), all members
of the Committee shall be both "non-employee directors" within the meaning of
Rule 16b-3 promulgated under the Exchange Act and "outside directors" within the
meaning of Code Section 162(m).  The Committee shall be appointed from time to
time by, and shall serve at the pleasure of, the Board of Directors.

     5.2. Grant of Options/Awards.
          -----------------------

     (a)  Options.  The Committee shall have the sole authority and discretion
          -------

hereunder; (ii) to designate whether any Option to be granted hereunder is to be
an ISO or a Non-Qualified Option; (iii) to establish the number of shares of
Common Stock that may be issued under each Option; (iv) to determine the time
and the conditions subject to which Options may be exercised in whole or in
part; (v) to determine the form of the consideration that may be used to
purchase shares of Common Stock upon exercise of any Option (including the
circumstances under which the Employee may pay all or part of the exercise price
by entering into a promissory note with the Company, or circumstances under
which the Company's issued and outstanding shares of Common Stock may be used by
a Participant to exercise an Option); (vi) to impose restrictions and/or
conditions with respect to shares of Common Stock acquired upon exercise of an
Option; (vii) to determine the circumstances under which shares of Common Stock
acquired upon exercise of any Option may be subject to repurchase by the
Company; (viii) to determine the circumstances and conditions subject to which
shares acquired upon exercise of an Option may be sold or otherwise transferred,
including, without limitation, the

                                       3
<PAGE>

circumstances and conditions subject to which a proposed sale of shares of
Common Stock acquired upon exercise of an Option may be subject to the Company's
right of first refusal (as well as the terms and conditions of any such right of
first refusal); (ix) to establish a vesting provision for any Option relating to
the time when (or the circumstances under which) the Option may be exercised by
a Participant, including, without limitation, vesting provisions that may be
contingent upon (A) the Company meeting specified financial goals, (B) a change
of control of the Company or (C) the occurrence of other specified events; (x)
to accelerate the time when outstanding Options may be exercised; and (xi) to
establish any other terms, restrictions and/or conditions applicable to any
Option not inconsistent with the provisions of the Plan.

     (b)   Awards. The Committee shall have the sole authority and discretion
           ------
under the Plan (i) to select the Employees who are to be granted Awards
hereunder; (ii) to determine the amount, if any, to be paid by a Participant to
acquire shares of Common Stock pursuant to an Award; (iii) to determine the time
or times and the conditions subject to which Awards may be made; (iv) to
determine the time or times and the conditions subject to which the shares of
Common Stock subject to an Award are to become vested and no longer subject to
forfeiture to and/or repurchase by the Company; (v) to establish transfer
restrictions and the terms and conditions on which any such transfer
restrictions with respect to shares of Common Stock acquired pursuant to an
Award shall lapse; (vi) to establish vesting provisions with respect to any
shares of Common Stock subject to an Award, including, without limitation,
vesting provisions which may be contingent upon (A) the Company meeting
specified financial goals, (B) a change of control of the Company or (C) the
occurrence of other specified events; (vii) to determine the circumstances under
which shares of Common Stock acquired pursuant to an Award may be subject to
repurchase by the Company; (viii) to determine the circumstances and conditions
subject to which any shares of Common Stock acquired pursuant to an Award may be
sold or otherwise transferred, including, without limitation, the circumstances
and conditions subject to which a proposed sale of shares of Common Stock
acquired pursuant to an Award may be subject to the Company's right of first
refusal (as well as the terms and conditions of any such right of first
refusal); (ix) to determine the form of consideration that may be used to
purchase shares of Common Stock pursuant to an Award (including the
circumstances under which the Company's issued and outstanding shares of Common
Stock may be used by a Participant to purchase the Common Stock subject to an
Award); (x) to accelerate time at which any or all restrictions imposed with
respect to any shares of Common Stock subject to an Award will lapse; and (xi)
to establish any other terms, restrictions and/or conditions applicable to any
Award not inconsistent with the provisions of the Plan.

     5.3.  Interpretation.  The Committee shall be authorized to interpret the
           --------------
Plan and may, from time to time, adopt such rules and regulations, not
inconsistent with the provisions of the Plan, as it may deem advisable to carry
out the purposes of the Plan.

     5.4.  Finality.  The interpretation and construction by the Committee of
           --------
any provision of the Plan, any Option and/or Award granted hereunder or any
agreement evidencing any such Option and/or Award shall be final and conclusive
upon all parties.

     5.5.  Voting.  Members of the Committee may vote on any matter affecting
           ------
the administration of the Plan or the granting of Options and/or Awards under
the Plan.

     5.6.  Expenses, Etc.  All expenses and liabilities incurred by the
           -------------
Committee in the administration of the Plan shall be borne by the Company. The
Committee may employ

                                       4
<PAGE>

attorneys, consultants, accountants or other persons in connection with the
administration of the Plan. The Company, and its officers and directors, shall
be entitled to rely upon the advice, opinions or valuations of any such persons.

     5.7.  Indemnification.  Neither the members of the Board of Directors nor
           ---------------
any member of the Committee shall be liable for any act, omission, or
determination taken or made in good faith with respect to the Plan or any
Options or Awards granted under it, and members of the Board of Directors and
the Committee shall be entitled to indemnification and reimbursement by the
Company in respect of any claim, loss, damage, or expense (including attorneys'
fees, the costs of settling any suit, provided such settlement is approved by
independent legal counsel selected by the Company, and amounts paid in
satisfaction of a judgment, except a judgment based on a finding of bad faith)
arising therefrom to the full extent permitted by law.

    Section 6.  Terms and Conditions of Options.
                 ------------------------------

     6.1.  ISOs.  The terms and conditions of each ISO granted under the Plan
           ----
shall be specified by the Committee and shall be set forth in an ISO agreement
between the Company and the Participant in such form as the Committee shall
approve. The terms and conditions of each ISO shall be such that each ISO issued
hereunder shall constitute and shall be treated as an "incentive stock option"
as defined in Section 422(b) of the Code. The terms and conditions of any ISO
granted hereunder need not be identical to those of any other ISO granted
hereunder.

     The terms and conditions of each ISO shall include the following:

     (a)   The option price shall be fixed by the Committee but shall in no
event be less than 100% (or 110% in the case of an Employee referred to in
Section 4.3(b) hereof) of the fair market value of the shares of Common Stock
subject to the ISO on the date the ISO is granted. For purposes of the Plan, the
fair market value per share of Common Stock as of any day shall mean the average
of the closing prices of sales of shares of Common Stock on all national
securities exchanges on which the Common Stock may at the time be listed or, if
there shall have been no sales on any such day, the average of the highest bid
and lowest asked prices on all such exchanges at the end of such day, or, if on
any day the Common Stock shall not be so listed, the average of the
representative bid and asked prices quoted in the NASDAQ system as of 3:30 p.m.,
New York time, on such day, or, if on any day the Common Stock shall not be
quoted in the NASDAQ system, the average of the high and low bid and asked
prices on such day in the over-the-counter market as reported by National
Quotation Bureau Incorporated, or any similar successor organization. If at any
time the Common Stock is not listed on any national securities exchange or
quoted in the NASDAQ system or the over-the-counter market, the fair market
value of the shares of Common Stock subject to an Option on the date the ISO is
granted shall be the fair market value thereof determined in good faith by the
Board of Directors. The fair market value of Common Stock subject to an ISO
shall be determined without regard to any restriction other than a restriction
which, by its terms, will never lapse.

     (b)   ISOs, by their terms, shall not be transferable otherwise than by
will or the laws of descent and distribution, and, during an Optionee's
lifetime, an ISO shall be exercisable only by the Optionee.


                                       5
<PAGE>

     (c)   All ISOs must be granted within 10 years of the earlier of the date
the Plan is adopted or the date the Plan is approved by the shareholders of the
Company. The Committee shall fix the term of all ISOs granted pursuant to the
Plan (including the date on which such ISO shall expire and terminate),
provided, however, that such term shall in no event exceed ten years from the
- --------  -------
date on which such ISO is granted (or, in the case of an ISO granted to an
Employee referred to in Section 4.3(b) hereof, such term shall in no event
exceed five years from the date on which such ISO is granted). Each ISO shall be
exercisable in such amount or amounts, under such conditions and at such times
or intervals or in such installments as shall be determined by the Committee in
its sole discretion.

     (d)   To the extent that the Company or any Parent or Subsidiary of the
Company is required to withhold any Federal, state or local taxes in respect of
any compensation income realized by any Participant as a result of any
"disqualifying disposition" of any shares of Common Stock acquired upon exercise
of an ISO granted hereunder, the Company shall deduct from any payments of any
kind otherwise due to such Participant the aggregate amount of such Federal,
state or local taxes required to be so withheld or, if such payments are
insufficient to satisfy such Federal, state or local taxes, such Participant
will be required to pay to the Company, or make other arrangements satisfactory
to the Company regarding payment to the Company of, the aggregate amount of any
such taxes. All matters with respect to the total amount of taxes to be withheld
in respect of any such compensation income shall be determined by the Board of
Directors in its sole discretion.

     (e)   In the sole discretion of the Committee the terms and conditions of
any ISO may (but need not) include any of the following provisions:

           (i)   In the event a Participant shall cease to be employed by the
     Company or any Parent or Subsidiary of the Company on a full-time basis for
     any reason other than as a result of his death or "disability" (within the
     meaning of Section 22(e)(3) of the Code), the unexercised portion of any
     ISO held by such Participant at that time may only be exercised within
     three (3) months after the date on which the Participant ceased to be so
     employed, and only to the extent that the Participant could have otherwise
     exercised such ISO as of the date on which he ceased to be so employed.

           (ii)  In the event a Participant shall cease to be employed by the
     Company or any Parent or Subsidiary of the Company on a full--time basis by
     reason of his "disability" (within the meaning of Section 22(e)(3) of the
     Code), the unexercised portion of any ISO held by such Participant at that
     time may only be exercised within one year after the date on which the
     Participant ceased to be so employed, and only to the extent that the
     Participant could have otherwise exercised such ISO as of the date on which
     he ceased to be so employed.

           (iii) In the event a Participant shall die while in the full-time
     employ of the Company or a Parent or Subsidiary of the Company (or within a
     period of three (3) months after ceasing to be an Employee for any reason
     other than his "disability" or within a period of one year after ceasing to
     be an Employee by reason of such "disability"), the unexercised portion of
     any ISO held by such Participant at the time of his death may only be
     exercised within one year after the date of such Participant's death, and
     only to the extent that the Participant could have otherwise exercised such
     ISO at the time of his death. In such event, such ISO may be exercised by
     the executor

                                       6
<PAGE>

     or administrator of the Participant's estate or by any person amish persons
who shall have acquired the ISO directly from the Participant by bequest or
inheritance.

     (f)   No Option granted hereunder shall qualify as an ISO unless the Plan
is approved by the shareholders of the Company within 12 months before or after
the date the Plan is adopted by the Board of Directors.

     6.2.  Non-Qualified Options.  The terms and conditions of each Non-
           ---------------------
Qualified Option granted under the Plan shall be specified by the Committee, in
its sole discretion, and shall be set forth in a written option agreement
between the Company and the Participant in such form as the Committee shall
approve. The terms and conditions of each Non-Qualified Option will be such (and
each Non-Qualified Option Agreement shall expressly so state) that each Non-
Qualified Option issued hereunder shall not constitute nor be treated as an
"incentive stock option" as defined in Section 422(b) of the Code but will be a
"non-qualified stock option" for Federal, state and local income tax purposes.
The terms and conditions of any Non-Qualified Option granted hereunder need not
be identical to those of any other Non-Qualified Option granted hereunder.

     The terms and conditions of each Non-Qualified Option Agreement shall
include the following:

     (a)   The option (exercise) price shall be fixed by the Committee and may
be equal to, more than or less than 100% of the fair market value of the shares
of Common Stock subject to the Non-Qualified Option on the date such Non-
Qualified Option is granted, provided, however, that the option (exercise) price
                             --------  -------
shall not be less than the par value of such shares of Common Stock.

     (b)   The Committee shall fix the term of all Non-Qualified Options granted
pursuant to the Plan (including the date on which such Non--Qualified Option
shall expire and terminate).  Each Non-Qualified Option shall be exercisable in
such amount or amounts, under such conditions (including provisions governing
the rights to exercise such Non--Qualified Option), and at such times or
intervals or in such installments as shall be determined by the Committee in its
sole discretion.

     (c)   Except as otherwise provided in an individual Option Agreement, Non-
Qualified Options shall not be transferable otherwise than by will or the laws
of descent and distribution, or a domestic relations order, and during a
Participant's lifetime a Non-Qualified Option shall be exercisable only by the
Participant or an alternate payee under a domestic relations order.

     (d)   To the extent that the Company is required to withhold any Federal,
state or local taxes in respect of any compensation income realized by any
Participant in respect of a Non-Qualified Option granted hereunder or in respect
of any shares of Common Stock acquired upon exercise of a Non-Qualified Option,
the Company shall deduct from any payments of any kind otherwise due to such
Participant the aggregate amount of such Federal, state or local taxes required
to be so withheld or, if such payments are insufficient to satisfy such Federal,
state or local taxes, or if no such payments are due or to become due to such
Participant, then, such Participant will be required to pay to the Company, or
make other arrangements satisfactory to the Company (including, with prior
Committee approval, use of a promissory note in favor of the Company) regarding
payment to the Company of, the


                                       7
<PAGE>

aggregate amount of any such taxes. All matters with respect to the total amount
of taxes to be withheld in respect of any such compensation income shall be
determined by the Board of Directors in its sole discretion.

     Section 7.  Terms and Conditions of Awards.  The terms and conditions of
                 ------------------------------
each Award granted under the Plan shall be specified by the Committee, in its
sole discretion, and shall be set forth in a written agreement between the
Participant and the Company, in such form as the Committee shall approve. The
terms and provisions of any Award granted hereunder need not be identical to
those of any other Award granted hereunder.

     The terms and conditions of each Award shall include the following:

     (a)   The amount, if any, to be paid by a Participant to acquire the shares
of Common Stock pursuant to an Award shall be fixed by the Board of Directors
(or the Committee).

     (b)   Each Award shall contain such vesting provisions, such transfer
restrictions and such other restrictions and conditions as the Committee, in its
sole discretion, may determine, including, without limitation, the circumstances
under which the Company shall have the right and option to repurchase shares of
Common Stock acquired pursuant to an Award.

     (c)   Stock certificates representing Common Stock acquired pursuant to an
Award shall bear a legend referring to the restrictions imposed on such Stock
and such other matters as the Committee may determine.

     (d)   To the extent that the Company is required to withhold any Federal,
state or local taxes in respect of any compensation income realized by the
Participant in respect of an Award granted hereunder, or in respect of any
shares acquired pursuant to an Award, or in respect of the vesting of any such
shares of Common Stock, then the Company shall deduct from any payments of any
kind otherwise due to such Participant the aggregate amount of such Federal,
state or local taxes required to be so withheld or, if such payments are
insufficient to satisfy such Federal, state or local taxes, or if no such
payments are due or to become due to such Participant, then, such Participant
will be required to pay to the Company, or make other arrangements satisfactory
to the Company regarding payment to the Company of, the aggregate amount of any
such taxes. All matters with respect to the total amount of taxes to be withheld
in respect of any such compensation income shall be determined by the Committee
in its sole discretion.

     Section 8.  Adjustments.  In the event that, after the adoption of the Plan
                 -----------
by the Board of Directors, the outstanding shares of the Company's Common Stock
shall be increased or decreased or changed into or exchanged for a different
number or kind of shares of stock or other securities of the Company or of
another corporation through reorganization, merger or consolidation,
recapitalization, reclassification, stock split, split-up, combination or
exchange of shares or declaration of any dividends payable in Common Stock, the
Board of Directors shall appropriately adjust (i) the number of shares of Common
Stock (and the option price per share) subject to the unexercised portion of any
outstanding Option (to the nearest possible full share), provided, however, that
                                                         --------  -------
the limitations of Section 424 of the Code shall apply with respect to
adjustments made to ISOs; (ii) the number of shares of Common Stock to be
acquired pursuant to an Award which have not become vested, and (iii) the number
of shares


                                       8
<PAGE>

of Common Stock for which Options and/or Awards may be granted under
the Plan, as set forth in Section 4.1 hereof, and such adjustments shall be
effective and binding for all purposes of the Plan.  The number of shares
authorized in Section 4.1 reflects the three-for-one reverse split of the common
stock effected in May 2000.

     Section 9.  Effect of the Plan on Employment Relationship.  Neither the
                 ---------------------------------------------
Plan nor any Option and/or Award granted hereunder to a Participant shall be
construed as conferring upon such Participant any right to continue in the
employ of (or otherwise provide services to) the Company or any Subsidiary or
Parent thereof, or limit in any respect the right of the Company or any
Subsidiary or Parent thereof to terminate such Participant's employment or other
relationship with the Company or any Subsidiary or Parent, as the case may be,
at any time.

     Section 10. Amendment of the Plan.  The Committee or Board of Directors
                 ---------------------
may amend or suspend the Plan or any portion thereof at any time, provided such
amendment is made with stockholder approval if such approval is necessary to
comply with any tax or regulatory requirement, including for these purposes any
approval which is a requirement for ISO treatment or, if applicable once any
equity securities of the Company become registered under Section 12 of the
Exchange Act, for exemptive relief under Section 16(b) of the Exchange Act or
which is a requirement for the performance-based compensation exception under
Code Section 162(m). The Committee in its sole discretion may amend the Plan so
as to conform with local rules and regulations subject to any provisions to the
contrary specified herein.

     Section 11. Amendment of an Option or Award Agreement.  In its sole and
                 -----------------------------------------
complete discretion, the Committee may at any time amend any Option or Award
Agreement for the following reasons: (i) additions and/or changes to the Code,
any federal or state securities law, or other law or regulations applicable to
the Option or Award, are made, and such additions and/or changes have some
effect on the Option or Award; or (ii) any other event not described in clause
(i) occurs and the Participant gives his or her consent to such amendment,
provided however, except for capital adjustments described in Section 8, the
Committee may not reduce the exercise price of an Option or Award.

     Section 12. Exemption from Computation of Compensation for Other Purposes.
                 -------------------------------------------------------------
By acceptance of an applicable Option or Award, subject to the conditions of
such Option or Award, each Participant shall be considered in agreement that all
shares sold or awarded and all Options granted under this Plan shall be
considered special incentive compensation and will be exempt from inclusion as
"wages" or "salary" in pension, retirement, life insurance, and other employee
benefits arrangements of the Company, except as determined otherwise by the
Company. In addition, each beneficiary of a deceased Participant shall be in
agreement that all such Options and Awards will be exempt from inclusion in
"wages" or "salary" for purposes of calculating benefits of any life insurance
coverage sponsored by the Company.

     Section 13. Listing, Registration and Other Legal Compliance.  No Options,
                 ------------------------------------------------
Awards or shares of the Common Stock shall be required to be issued or granted
under the Plan unless legal counsel to the Company shall be satisfied that such
issuance or grant will be in compliance with all applicable federal and state
securities laws and regulations and any other applicable laws or regulations.
The Committee may require, as a condition of any payment or share issuance, that
certain agreements, undertakings, representations, certificates, and/or
information, as the Committee may deem necessary or advisable, be executed or
provided to the Company to assure compliance with all such applicable laws or
regulations. Any


                                       9
<PAGE>

certificates for shares of Common Stock delivered under the Plan may be subject
to such stock-transfer orders and such other restrictions as the Committee may
deem advisable under the rules, regulations, or other requirements of the
Securities and Exchange Commission, any stock exchange upon which the Common
Stock is then listed, and any applicable federal or state securities law. In
addition, if, at any time specified herein (or in any Agreement or otherwise)
for (a) the making of any Option or Award, or the making of any determination,
(b) the issuance or other distribution of Common Stock, or (c) the payment of
amounts to or through a Participant with respect to any Option or Award, any
law, rule, regulation, or other requirement of any governmental authority or
agency shall require the Company, any affiliate, or any Participant (or any
estate, designated beneficiary, or other legal representative thereof) to take
any action in connection with any such determination, any such shares to be
issued or distributed, any such payment, or the making of any such
determination, as the case may be, shall be deferred until such required action
is taken.

     Section 14.  Rights as Stockholder.  Subject to the Award provisions, no
                  ---------------------
Participant or beneficiary shall be deemed a stockholder of the Company nor have
any rights as such with respect to any shares to be provided under the Plan
until he or she has become the holder of such shares. Notwithstanding the
aforementioned, with respect to restricted stock Awards under this Plan, the
Participant or beneficiary of such Award shall be deemed the owner of such
shares provided herein. As such, unless contrary to the provisions herein or in
any such related Agreement, such stockholder shall be entitled to full voting,
dividend and distribution rights as provided any other Company stockholder for
as long as the Participant continues to be deemed the owner of such stock.

     Section 15.  Construction of the Plan.  The Plan, and its rules, rights,
                  ------------------------
agreements and regulations, shall be governed, construed, interpreted and
administered solely in accordance with the laws of the state of Delaware. In the
event any provision of the Plan shall be held invalid, illegal or unenforceable,
in whole or in part, for any reason, such determination shall not affect the
validity, legality or enforceability of any remaining provision, portion of
provision or the Plan overall, which shall remain in full force and effect as if
the Plan had been absent the invalid, illegal or unenforceable provision or
portion thereof

     Section 16.  Termination of the Plan.  The Board of Directors may terminate
                  -----------------------
the Plan at any time. Unless the Plan shall theretofore have been terminated by
the Board of Directors, the Plan shall terminate ten years after the date of its
initial adoption by the Board of Directors. No Option and/or Award may be
granted hereunder after termination of the Plan. The termination or amendment of
the Plan shall not alter or impair any rights or obligations under any Option
and/or Award theretofore granted under the Plan.

     Section 17.  Effective Date of the Plan.  The Plan shall be effective as of
                  --------------------------
1st  February, 1998, the date on which the Plan was adopted by the Board of
Directors of the Company.

                                                                   EXHIBIT 10.12


                             AIRSPAN NETWORKS INC.

                       2000 EMPLOYEE STOCK PURCHASE PLAN

                     As approved by the Board of Directors
                         on May 17, 2000 and Airspan's
                          Shareholders on May 24, 2000


     Airspan Networks Inc. (the "Company") does hereby establish its 2000
Employee Stock Purchase Plan as follows:

     1.   Purpose of the Plan.  The purpose of this Plan is to provide eligible
employees who wish to become shareholders in the Company a convenient method of
doing so.  It is believed that employee participation in the ownership of the
business will be to the mutual benefit of both the employees and the Company.

     2.   Definitions.

          2.1  "Base pay" means regular straight time earnings, plus review
cycle bonuses, payments for incentive compensation, and other special payments
except to the extent that any such item is specifically excluded by the Board of
Directors of the Company (the "Board").

          2.2  "Account" shall mean the funds accumulated with respect to an
individual employee as a result of deductions from his paycheck for the purpose
of purchasing stock under this Plan. The funds allocated to an employee's
account shall remain the property of the respective employee at all times but
may be commingled with the general funds of the Company.

     3.   Employees Eligible to Participate.  Any employee of the Company or any
of its subsidiaries who is in the employ of the Company or subsidiary on an
Offering commencement date is eligible to participate in that Offering, except
(a) employees whose customary employment is less than 20 hours per week, and (b)
employees whose customary employment is for not more than five months in any
calendar year.

     4.   Offerings.  There will be six separate consecutive offerings (each an
"Offering") pursuant to the Plan.  The first Offering shall commence on the date
on which the Company's registration statement for the registration under the
Securities Act of 1933, as amended, of shares of the common stock of the Company
becomes effective (the "IPO Date"), and shall continue through July 31 , 2001.
Thereafter, Offerings shall commence on each subsequent August 1 and shall last
for a period of one year, and the final Offering under this Plan shall commence
on August 1, 2005 and terminate on July 31, 2006.  In order to become eligible
to purchase shares, an employee must sign an Enrollment Agreement, and any other
necessary papers on or before the commencement date (the IPO Date or August 1,
as applicable) of the particular Offering in which he wishes to participate.
Participation in one Offering under the Plan shall neither limit, nor require,
participation in any other Offering.

     5.   Price.
<PAGE>

          5.1 The first Offering

          The purchase price per share shall be the lesser of (1) 85% of the
          fair market value of the stock on the IPO Date; or (2) 85% of the fair
          market value of the stock on the last business day of the first
          Offering.  Fair market value shall mean the closing bid price as
          reported on the National Association of Securities Dealers Automated
          Quotation System or, if the stock is traded on a stock exchange, the
          closing price for the stock on the principal such exchange.

          5.2 Subsequent Offerings

          The purchase price per share shall be the lesser of (1) 85% of the
          fair market value of the stock on the Offering date; or (2) 85% of the
          fair market value of the stock on the last business day of the
          Offering.  Fair market value shall mean the closing bid price as
          reported on the National Association of Securities Dealers Automated
          Quotation System or, if the stock is traded on a stock exchange, the
          closing price for the stock on the principal such exchange.

     6.   Offering Date.  The "offering date" as used in this Plan shall be
the commencement date of the Offering, if such date is a regular business day,
or the first regular business day following such commencement date.  A different
date may be set by resolution of the Board.

     7.   Number of Shares to be Offered.  The maximum number of shares that
will be offered under the Plan is 500,000 shares.  The shares to be sold to
participants under the Plan will be common stock of the Company.  If the total
number of shares for which options are to be granted on any date in accordance
with Section 10 exceeds the number of shares then available under the Plan
(after deduction of all shares for which options have been exercised or are then
outstanding), the Company shall make a pro rata allocation of the shares
remaining available in as nearly a uniform manner as shall be practicable and as
it shall determine to be equitable.  In such event, the payroll deductions to be
made pursuant to the authorizations therefor shall be reduced accordingly and
the Company shall give written notice of such reduction to each employee
affected thereby.

     8.   Participation.

          8.1  An eligible employee may become a participant by completing an
Enrollment Agreement provided by the Company and filing it with Shareholder
Services prior to the Commencement of the Offering to which it relates.

          8.2  Payroll deductions for a participant shall commence on the
offering date, and shall end on the termination date of such Offering unless
earlier terminated by the employee as provided in Paragraph 14.

     9.   Payroll Deductions.

          9.1  At the time a participant files his authorization for a payroll
deduction, he shall elect to have deductions made from his pay on each payday
during the time he is a participant in an Offering at the rate of 2%, 4%, 6%,
8%, or 10% of his base pay.
<PAGE>

          9.2  All payroll deductions made for a participant shall be credited
to his account under the Plan.  A participant may not make any separate cash
payment into such account nor may payment for shares be made other than by
payroll deduction.

          9.3  A participant may discontinue his participation in the Plan as
provided in Section 14, but no other change can be made during an Offering and,
specifically, a participant may not alter the rate of his payroll deductions for
that Offering.

     10.  Granting of Option. On the offering date, this Plan shall be deemed to
have granted to the participant an option for as many shares as he will be able
to purchase with the payroll deductions credited to his account during his
participation in that Offering.

     11.  Exercise of Option. Each employee who continues to be a participant in
an Offering on the last business day of that Offering shall be deemed to have
exercised his option on such date and shall be deemed to have purchased from the
Company such number of shares of common stock reserved for the purpose of the
Plan as his accumulated payroll deductions on such date will pay for at the
option price.

     12.  Employee's Rights as a Shareholder. No participating employee shall
have any right as a shareholder with respect to any shares until the shares have
been purchased in accordance with Section 11 above and the stock has been issued
by the Company.

     13.  Evidence of Stock Ownership.

          13.1  Promptly following the end of each Offering, the number of
shares of common stock purchased by each participant shall be deposited into an
account established in the participant's name at a stock brokerage or other
financial services firm designated by the Company (the "ESPP Broker").

          13.2  The participant may direct, by written notice to the Company at
the time of his enrollment in the Plan, that his ESPP Broker account be
established in the names of the participant and one other person designated by
the participant, as joint tenants with right of survivorship, tenants in common,
or community property, to the extent and in the manner permitted by applicable
law.

          13.3  A participant shall be free to undertake a disposition (as that
term is defined in Section 424(c) of the Code) of the shares in his account at
any time, whether by sale, exchange, gift, or other transfer of legal title, but
in the absence of such a disposition of the shares, the shares must remain in
the participant's account at the ESPP Broker until the holding period set forth
in Section 423(a) of the Code has been satisfied.  With respect to shares for
which the Section 423(a) holding period has been satisfied, the participant may
move those shares to another brokerage account of participant's choosing or
request that a stock certificate be issued and delivered to him.

          13.4  A participant who is not subject to payment of U.S. income taxes
may move his shares to another brokerage account of his choosing or request that
a stock certificate be issued and delivered to him at any time, without regard
to the satisfaction of the Section 423(a) holding period.
<PAGE>

     14.  Withdrawal.

          14.1  An employee may withdraw from an Offering, in whole but not in
part, at any time prior to the last business day of such Offering by delivering
a Withdrawal Notice to the Company, in which event the Company will refund the
entire balance of his deductions as soon as practicable thereafter.

          14.2  To re-enter the Plan, an employee who has previously withdrawn
must file a new Enrollment Agreement in accordance with Section 8.1.  The
employee's re-entry into the Plan will not become effective before the beginning
of the next Offering following his withdrawal, and if the withdrawing employee
is an officer of the Company within the meaning of Section 16 of the Securities
Exchange Act of 1934 he may not re-enter the Plan before the beginning of the
second Offering following his withdrawal.

     15.  Carryover of Account. At the termination of each Offering the Company
shall automatically re-enroll the employee in the next Offering, and the balance
in the employee's account shall be used for option exercises in the new
Offering, unless the employee has advised the Company otherwise. Upon
termination of the Plan, the balance of each employee's account shall be
refunded to him.

     16.  Interest. No interest will be paid or allowed on any money in the
accounts of participating employees.

     17.  Rights Not Transferable. No employee shall be permitted to sell,
assign, transfer, pledge, or otherwise dispose of or encumber either the payroll
deductions credited to his account or any rights with regard to the exercise of
an option or to receive shares under the Plan other than by will or the laws of
descent and distribution, and such right and interest shall not be liable for,
or subject to, the debts, contracts, or liabilities of the employee. If any such
action is taken by the employee, or any claim is asserted by any other party in
respect of such right and interest whether by garnishment, levy, attachment or
otherwise, such action or claim will be treated as an election to withdraw funds
in accordance with Section 14.

     18.  Termination of Employment. Upon termination of employment for any
reason whatsoever, including but not limited to death or retirement, the balance
in the account of a participating employee shall be paid to the employee or his
estate.

     19.  Amendment or Discontinuance of the Plan. The Board shall have the
right to amend, modify, or terminate the Plan at any time without notice,
provided that no employee's existing rights under any Offering already made
under Section 4 hereof may be adversely affected thereby, and provided further
that no such amendment of the Plan shall, except as provided in Section 20,
increase above 750,000 shares the total number of shares to be offered unless
shareholder approval is obtained therefor.

     20.  Changes in Capitalization. In the event of reorganization,
recapitalization, stock split, stock dividend, combination of shares, merger,
consolidation, offerings of rights, or any other change in the structure of the
common shares of the Company, the Board may make such adjustment, if any, as it
may deem appropriate in the number, kind, and the price of shares available for
purchase under the Plan, and in the number of shares which an employee is
entitled to purchase.
<PAGE>

     21.  Share Ownership. Notwithstanding anything herein to the contrary, no
employee shall be permitted to subscribe for any shares under the Plan if such
employee, immediately after such subscription, owns shares (including all shares
which may be purchased under outstanding subscriptions under the Plan)
possessing 5% or more of the total combined voting power or value of all classes
of shares of the Company or of its parent or subsidiary corporations. For the
foregoing purposes the rules of Section 425(d) of the Internal Revenue Code of
1986 shall apply in determining share ownership. In addition, no employee shall
be allowed to subscribe for any shares under the Plan which permits his rights
to purchase shares under all "employee stock purchase plans" of the Company and
its subsidiary corporations to accrue at a rate which exceeds $25,000 of the
fair market value of such shares (determined at the time such right to subscribe
is granted) for each calendar year in which such right to subscribe is
outstanding at any time.

     22.  Administration. The Plan shall be administered by the Board. The Board
may delegate any or all of its authority hereunder to such committee of the
Board or officer of the Company as it may designate. The administrator shall be
vested with full authority to make, administer, and interpret such rules and
regulations as it deems necessary to administer the Plan, and any determination,
decision, or action of the administrator in connection with the construction,
interpretation, administration, or application of the Plan shall be final,
conclusive, and binding upon all participants and any and all persons claiming
under or through any participant.

     23.  Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received by Shareholder Services of the Company or when received in
the form specified by the Company at the location, or by the person, designated
by the Company for the receipt thereof.

     24.  Termination of the Plan. This Plan shall terminate at the earliest of
the following:

          24.1  July 31, 2006.

          24.2  The date of the filing of a Statement of Intent to Dissolve by
the Company or the effective date of a merger or consolidation wherein the
Company is not to be the surviving corporation, which merger or consolidation is
not between or among corporations related to the Company.  Prior to the
occurrence of either of such events, on such date as the Company may determine,
the Company may permit a participating employee to exercise the option to
purchase shares for as many shares as the balance of his account will allow at
the price set forth in accordance with Section 5.  If the employee elects to
purchase shares, the remaining balance of his account will be refunded to him
after such purchase.

          24.3  The date the Board acts to terminate the Plan in accordance
with Section 19 above.

          24.4  The date when all shares reserved under the Plan have been
purchased.

     25.  Limitations on Sale of Stock Purchased Under the Plan.  The Plan
is intended to provide common stock for investment and not for resale.  The
Company does not, however, intend to restrict or influence any employee in the
conduct of his own affairs.  An employee, therefore, may sell stock purchased
under the Plan at any time he chooses, subject to compliance
<PAGE>

with any applicable Federal or state securities laws. THE EMPLOYEE ASSUMES THE
RISK OF ANY MARKET FLUCTUATIONS IN THE PRICE OF THE STOCK.

     26.  Governmental Regulation. The Company's obligation to sell and deliver
shares of the Company's common stock under this Plan is subject to the approval
of any governmental authority required in connection with the authorization,
issuance, or sale of such shares.
