PROSPECTUS.

VYYO

We supply broadband wireless access systems used by communications service
providers to deliver wireless, high-speed data connections to business and
residential subscribers. Our systems enable data transmission between a service
provider's central location and multiple subscribers, based on the networking
standard used to deliver voice and data over the Internet. Our systems are
designed to allow service providers to rapidly and cost-effectively bridge the
segment of the network that connects the service providers' systems directly to
subscribers, commonly referred to as the last mile. Our first-generation
broadband wireless access system has been commercially deployed at 21 domestic
and international sites and the initial commercial deployment of our
second-generation system occurred in the first quarter of 2000.

Internet and data network traffic growth has created demand for
cost-effective, high-speed communications, as subscribers increasingly rely on
content-rich applications and remote access to data networks. In the United
States and abroad, the communications industry is in varying stages of
deregulation, which has created the opportunity for new competitors to use
existing and emerging broadband technologies to offer multiple communications
services directly to subscribers. There are a number of broadband wire-based
technologies that do not utilize airwaves for data transport, but instead use
copper wire, fiber optic cable or other physical wires to transport voice and
data to and from points on a network. These wire-based technologies deliver
high-speed connections at transmission rates comparable to or, in the case of
fiber optic cable, faster than those delivered by most broadband wireless
technologies, but performance, cost, time for deployment or service availability
may limit the use of these alternative technologies to satisfy the needs of
service providers and subscribers. Broadband wireless technologies deliver
high-speed connections and offer service providers the ability to rapidly and
cost-effectively expand their current market coverage or to enter new markets
while avoiding the limitations of the existing wire-based infrastructure.

Our systems are deployed for use at the frequencies licensed for two-way
broadband communication at transmission rates comparable to most wire-based
technologies. Our second-generation system, which is based on the cable
industry's standard set of communications rules, or protocols, that we have
adopted for use in wireless applications, consists of a wireless hub, network
management system software and wireless subscriber modems. Each hub transmits,
receives and manages data traffic to and from our wireless modems, which are
installed at multiple subscriber locations. We sell our systems directly to
service providers and system integrators, who provide network planning and
integration services and integrate our systems with other components to provide
their customers with end-to-end network solutions.

<PAGE>
As key elements of our strategy, we intend to:

- use existing commercially deployed systems to demonstrate our
capabilities;

- broaden our product offerings;

- improve cost-effectiveness and performance of our systems;

- leverage key strategic relationships; and

- participate in the development of industry standards.

We began commercial shipments of our first-generation broadband wireless
access systems in the first quarter of 1999. We have a very limited operating
history in the broadband wireless access market upon which to evaluate our
future prospects. We have incurred significant losses since our inception. We
incurred net losses of approximately $43.6 million in 1999. As of December 31,
1999, our accumulated deficit was approximately $66.2 million. We expect to
continue to incur net losses for the foreseeable future.

We were incorporated in 1996 in Delaware under the name PhaseCom, Inc. In
January 2000, we changed our name to Vyyo Inc. Our principal executive offices
are located at 20400 Stevens Creek Boulevard, 8th Floor, Cupertino, California

RISK FACTORS

ANY INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU
SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE MAKING AN INVESTMENT
DECISION.

RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED OPERATING HISTORY IN THE BROADBAND POINT-TO-MULTIPOINT
WIRELESS ACCESS MARKET, WHICH MAY LIMIT YOUR ABILITY TO EVALUATE OUR BUSINESS
AND INCREASE THE RISK OF YOUR INVESTMENT.

The broadband wireless access market is only beginning to emerge. We began
commercial shipments of our first-generation broadband wireless access system in
the first quarter of 1999, and we began commercial shipments of our
second-generation wireless access system in the fourth quarter of 1999. All of
our product revenues in 1997 and 1998, and a substantial portion of our product
revenues in 1999, relate to sales of cable modem products that we are no longer
developing. Virtually all of the remaining revenues in 1999 relate to sales of
our first-generation wireless modem products, which we phased out with the
launch of our second-generation wireless access system in the fourth quarter of
that year. Our second generation wireless access system is based on the cable
industry's standard set of communications rules, or protocols, that we have
adopted for use in wireless applications. Therefore, the success of our business
will be entirely dependent upon the success of our wireless products generally,
and our new wireless products in particular. We have a very limited operating
history in the broadband wireless access market upon which to evaluate our
future prospects, and the revenue and income potential of our business and
market are unproven. Our limited operating history in this market may limit your
ability to evaluate our prospects due to:

- our limited historical financial data from our wireless products;

- our unproven potential to generate profits; and

- our limited experience in addressing emerging trends that may affect our
business.

As a young company, we face risks and uncertainties relating to our ability
to implement our business plan successfully. You should consider our prospects
in light of the risks, expenses and difficulties we may encounter.

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

We have incurred significant losses since our inception, and we expect to
continue to incur net losses for the foreseeable future. We incurred net losses
of approximately $43.6 million in 1999. As of December 31, 1999, our accumulated
deficit was approximately $66.2 million. We intend to significantly increase our
operating expenses, especially our marketing and selling expenses, and our
research and

5
<PAGE>
development expenses. However, our revenues may not grow or even continue at
their current level. If our revenues do not rapidly increase or if our expenses
increase at a greater pace than our revenues, we will never become profitable.

OUR QUARTERLY OPERATING RESULTS FLUCTUATE, WHICH MAY CAUSE OUR SHARE PRICE TO
DECLINE.

Our quarterly operating results have varied significantly in the past and
are likely to vary significantly in the future. These variations result from a
number of factors, including:

- the uncertain timing and level of market acceptance for our systems;

- the effectiveness of our system integrator customers in marketing and
selling their network systems equipment;

- reductions in pricing by us or our competitors;

- the mix of systems sold by us and the mix of sales channels through which
they are sold; and

- changes in the prices or delays in deliveries of the components we
purchase or license.

A delay in the recognition of revenue, even from one customer, may have a
significant negative impact on our results of operations for a given period. We
have experienced such delays in the past, and our results of operations for
those periods were negatively impacted. Also, because only a small portion of
our expenses vary with our revenues, if revenue levels for a quarter fall below
our expectations, we will not be able to timely adjust expenses accordingly,
which would harm our operating results in that period. We believe that
period-to-period comparisons of our results of operations are not meaningful and
should not be relied upon as indicators of future performance. If our operating
results fall below the expectations of investors in future periods, our share
price will likely decline.

IF BROADBAND WIRELESS TECHNOLOGY OR OUR IMPLEMENTATION OF THIS TECHNOLOGY IS NOT
BROADLY ACCEPTED, WE WILL NOT BE ABLE TO SUSTAIN OR EXPAND OUR BUSINESS.

Our future success depends on high-speed wireless communications products
gaining market acceptance as a means to provide voice and data communications
services. Because these markets are relatively new, it is difficult to predict
which market segments will develop or expand. We have recently invested and
expect to continue to invest significant time and resources in the development
of new products for this market. In the event that service providers adopt
technologies other than the high-speed access and other wireless technologies
that we offer, we will not be able to sustain or expand our business.

Service providers continually evaluate alternative technologies, including
digital subscriber line, fiber and cable. The failure of service providers to
accept our products would seriously harm our business.

6
<PAGE>
WE DEPEND ON ONE SYSTEM INTEGRATOR FOR A SIGNIFICANT PORTION OF OUR REVENUES AND
IF THIS SYSTEM INTEGRATOR DOES NOT PROMOTE OR PURCHASE OUR PRODUCTS, OUR
BUSINESS WILL BE SERIOUSLY HARMED.

We generated approximately 20% of our 1999 revenues from sales to
ADC Telecommunications. The loss of ADC Telecommunications as a customer, or the
delay of significant orders from it, even if only temporary, could, among other
things:

- reduce or delay our revenues;

- harm our reputation with major service providers, particularly if ADC
Telecommunications were to replace our products with a competitor's
products; or

- reduce our ability to predict our cash flow accurately.

Sales through ADC Telecommunications accounted for approximately 20% of our
net revenues for 1999 and approximately 31% of our net revenues for 1998. There
are a limited number of system integrators that have the financial resources or
technical expertise to sell or integrate our systems globally. If ADC
Telecommunications will not sell, service or integrate our products, and we
cannot secure other system integrators as replacements, we would be limited in
our ability to sell our products. ADC Telecommunications has the exclusive right
to market, sell and distribute our systems to MCI WorldCom, Sprint, BellSouth,
Wireless One and Irish Multi Channel. Should ADC Telecommunications cease to
emphasize systems that include our products, choose to emphasize alternative
technologies or promote systems of our competitors, our business would be
seriously harmed.

THE LOSS OF ONE OR MORE OF OUR KEY CUSTOMERS WOULD RESULT IN A LOSS OF A
SIGNIFICANT AMOUNT OF OUR REVENUES.

A relatively small number of customers account for a large percentage of our
revenues. In 1999, ADC Telecommunications accounted for approximately 20% of our
revenues, Aster City Cable accounted for approximately 14% of our revenues,
Shanghai Bell accounted for approximately 13% of our revenues and Philips
Semiconductor accounted for approximately 12% of our revenues. Revenues
attributable to Aster City Cable and Shanghai Bell relate to sales of cable
products that we are no longer developing. Accordingly, we do not anticipate
recognizing material amounts of revenue from these products in the future.
Revenues attributable to Philips Semiconductor relate to a joint technology
development arrangement that we expect to complete in 2000 and no similar
arrangements are contemplated.

We expect that we will continue to depend on a relatively limited number of
customers for a substantial portion of our revenues in future periods. The loss
of a major customer or the reduction, delay or cancellation of orders from one
or more of our customers could seriously harm our ability to sustain revenue
levels, which would seriously harm our operating results.

7
<PAGE>
COMPETITION MAY DECREASE OUR MARKET SHARE, NET REVENUES AND GROSS MARGINS, WHICH
MAY CAUSE OUR STOCK PRICE TO DECLINE.

The market for broadband access systems is intensely competitive, rapidly
evolving and subject to rapid technological change. Many of our competitors and
potential competitors have substantially greater financial, technical,
distribution, marketing and other resources than we have and, therefore, may be
able to respond more quickly to new or changing opportunities, technologies and
other developments. In addition, many of our competitors have longer operating
histories, greater name recognition and established relationships with system
integrators and service providers. Our primary competitor is Hybrid
Networks, Inc. In addition, well-capitalized companies such as Cisco Systems,
Lucent Technologies, Nortel Networks, Newbridge Networks and other vendors have
announced plans to enter, or are potential entrants into, the broadband wireless
market. Most of these competitors have existing relationships with one or more
of our prospective customers. We also face competition from technologies such as
digital subscriber line, fiber and cable. We may not be able to compete
successfully against our current and future competitors and competitive
pressures may seriously harm our business.

IF WE DO NOT DEVELOP NEW SYSTEMS AND SYSTEM FEATURES IN RESPONSE TO CUSTOMER
REQUIREMENTS OR IN A TIMELY WAY, CUSTOMERS MAY NOT BUY OUR PRODUCTS, WHICH WOULD
SERIOUSLY HARM OUR BUSINESS.

The broadband wireless access industry is rapidly evolving and subject to
technological change and innovation. We may experience design or manufacturing
difficulties that could delay or prevent our development, introduction or
marketing of new systems and enhancements, any of which could cause us to incur
unexpected expenses or lose revenues. If we are unable to comply with diverse,
new or varying governmental regulations or industry standards in each of the
many worldwide markets in which we compete, we may not be able to respond to
customers in a timely manner, which would harm our business.

WE DEPEND ON CONTRACT MANUFACTURERS AND THESE MANUFACTURERS MAY BE UNABLE TO
FILL OUR ORDERS ON A TIMELY BASIS, WHICH WOULD RESULT IN DELAYS THAT COULD
SERIOUSLY HARM OUR RESULTS OF OPERATIONS.

We currently have relationships with three contract manufacturers for the
manufacturing of our systems, two of which are located in Israel and one of
which is located in Taiwan. These relationships may be terminated by either
party with little or no notice. If our manufacturers are unable or unwilling to
continue manufacturing our systems in required volumes, we would have to
identify qualified alternative manufacturers, which would result in delays that
could cause our results of operations to suffer. Our limited experience with
these manufacturers does not provide us with a reliable basis on which to
project their ability to meet delivery schedules, yield targets or costs. If we
are required to find alternative manufacturing sources, we may not be

8
<PAGE>
able to satisfy our production requirements at acceptable prices and on a timely
basis, if at all. Any significant interruption in supply would affect the
allocation of systems to customers, which in turn could seriously harm our
business.

WE OBTAIN SOME OF THE COMPONENTS INCLUDED IN OUR SYSTEMS FROM A SINGLE SOURCE OR
A LIMITED GROUP OF SUPPLIERS, AND THE LOSS OF ANY OF THESE SUPPLIERS COULD CAUSE
PRODUCTION DELAYS AND A SUBSTANTIAL LOSS OF REVENUE.

We currently obtain key components from a limited number of suppliers. Some
of these components, such as semiconductor components for our wireless hubs, are
obtained from a single source supplier. We generally do not have long-term
supply contracts with our suppliers. These factors present us with the following
risks:

- delays in delivery or shortages in components could interrupt and delay
manufacturing and result in cancellation of orders for our systems;

- suppliers could increase component prices significantly and with immediate
effect;

- we may not be able to develop alternative sources for system components,
if or as required in the future;

- suppliers could discontinue the manufacture or supply of components used
in our systems. In such event, we might need to modify our systems, which
may cause delays in shipments, increased manufacturing costs and increased
systems prices; and

- we may hold more inventory than is immediately required to compensate for
potential component shortages or discontinuation.

The occurrence of any of these or similar events would harm our business.

DELAYS AND SHORTAGES IN THE SUPPLY OF COMPONENTS FROM OUR SUPPLIERS COULD REDUCE
OUR REVENUES OR INCREASE OUR COST OF REVENUE.

Delays and shortages in the supply of components are typical in our
industry. We have experienced minor delays and shortages on more than one
occasion in the past. In addition, any failure of necessary worldwide
manufacturing capacity to rise along with a rise in demand could result in our
subcontract manufacturers allocating available capacity to larger customers or
to customers that have long-term supply contracts in place. Our inability to
obtain adequate manufacturing capacity at acceptable prices, or any delay or
interruption in supply, could reduce our revenues or increase our cost of
revenue and could seriously harm our business.

9
<PAGE>
COMPETITION MAY RESULT IN LOWER AVERAGE SELLING PRICES AND WE MAY BE UNABLE TO
REDUCE OUR COSTS AT OFFSETTING RATES, WHICH MAY IMPAIR OUR ABILITY TO ACHIEVE OR
MAINTAIN PROFITABILITY.

We expect that price competition among broadband wireless access systems
suppliers will reduce our gross margins in the future. We anticipate that the
average selling prices of broadband wireless access systems will continue to
decline as product technologies mature. Since we do not manufacture our own
systems, we may be unable to reduce our manufacturing costs in response to
declining average per unit selling prices. Our competitors may be able to
achieve greater economies of scale and may be less vulnerable to the effects of
price competition than we are. These declines in average selling prices will
generally lead to declines in gross margins and total profitability for these
systems. If we are unable to reduce our costs to offset declines in average
selling prices, we may not be able to achieve or maintain profitability.

IF WE DO NOT EFFECTIVELY MANAGE OUR EXPANSION, OUR REVENUES MAY NOT INCREASE,
OUR COSTS MAY INCREASE AND OUR BUSINESS COULD BE SERIOUSLY HARMED.

We are continuing to actively expand our operations. This growth has placed,
and will continue to place, a significant strain on our managerial, operational
and financial resources. We also need to implement sophisticated inventory and
control systems.

To manage growth effectively, we must, among other things:

- improve and expand our information and financial systems, and managerial
procedures and controls;

- hire, train, manage and retain qualified employees; and

- effectively manage relationships with our customers, suppliers and other
third parties.

We may not have made adequate allowances for the costs and risks associated
with this expansion, our systems, procedures or controls may not be adequate to
support our operations, and our management may be unable to offer and expand our
product categories successfully. Any delay in implementing, or transitioning to,
new or enhanced systems, procedures or controls may seriously harm our ability
to record and report financial and management information on a timely and
accurate basis or otherwise manage our expanding operations. If we are unable to
do so effectively, our business may be seriously harmed.

BECAUSE WE OPERATE IN INTERNATIONAL MARKETS, WE ARE EXPOSED TO ADDITIONAL RISKS
WHICH COULD CAUSE OUR INTERNATIONAL SALES TO DECLINE AND OUR FOREIGN OPERATIONS
TO SUFFER.

Sales outside of North America accounted for approximately 39% of our
revenues in 1999 and 55% of our revenues in 1998. We expect that international
sales will continue to account for a significant portion of our revenues. In
addition, we

10
<PAGE>
maintain research and development facilities in Israel. Our reliance on
international sales and operations exposes us to foreign political and economic
risks, which may impair our ability to generate revenues. These risks include:

- economic and political instability;

- changes in regulatory requirements and licensing frequencies to service
providers;

- import or export licensing requirements and tariffs;

- trade restrictions; and

- more limited protection of intellectual property rights.

Any of the foregoing difficulties of conducting business internationally
could seriously harm our business.

BECAUSE WE DO NOT HAVE LONG-TERM CONTRACTS WITH OUR CUSTOMERS, OUR CUSTOMERS CAN
DISCONTINUE PURCHASES OF OUR SYSTEMS AT ANY TIME.

We sell our systems based on individual purchase orders. Our customers are
generally not obligated by long-term contracts to purchase our systems. Our
customers can generally cancel or reschedule orders on short notice and can
discontinue using our systems at any time. Further, having a successful system
trial does not necessarily mean that the customer will order large volumes of
our systems. The inability to retain our customers and increase their orders
would seriously harm our business.

IF OUR SENIOR MANAGEMENT TEAM IS UNABLE TO WORK TOGETHER EFFECTIVELY, OUR
BUSINESS MAY BE SERIOUSLY HARMED.

Several of our existing senior management personnel, including Michael
Corwin, our Chief Operating Officer, Eran Pilovsky, our Chief Financial Officer,
and Arnon Kohavi, our Senior Vice President of Strategic Relations, joined us in
the last nine months. As a result, our senior management team has had a limited
time to work together. If they are unable to work together effectively to manage
our organization as a public company, our business may be seriously harmed.

IF WE ARE UNABLE TO ATTRACT, TRAIN AND RETAIN QUALIFIED ENGINEERS, MARKETING,
SALES AND TECHNICAL SUPPORT PERSONNEL, WE MAY NOT BE ABLE TO DEVELOP OUR
BUSINESS.

We will need to hire additional engineers and highly trained technical
support personnel in Israel and in Northern California in order to succeed. We
will need to increase our technical staff to support new customers and the
expanding needs of existing customers, as well as for our continued research and
development operations.

Hiring engineers, marketing, sales and technical support personnel is very
competitive in our industry due to the limited number of people available with
the necessary skills and understanding of our products. This is particularly
true in Israel and Northern California, where competition for such personnel is
intense.

11
<PAGE>
Our systems require a sophisticated marketing and sales effort targeted at
several levels within a prospective customer's organization. We have recently
expanded our sales force and we plan to hire additional sales personnel,
particularly in the United States. Competition for qualified sales personnel is
intense, and we may not be able to hire sufficient sales personnel to support
our marketing efforts. If we are unable to hire and retain necessary personnel
in each of these rapidly expanding areas, our business will not develop, and our
operating results will be harmed.

WE DEPEND ON OUR KEY PERSONNEL, IN PARTICULAR DAVIDI GILO, OUR CHAIRMAN AND
CHIEF EXECUTIVE OFFICER, AND MENASHE SHAHAR, OUR VICE PRESIDENT, ENGINEERING AND
CHIEF TECHNICAL OFFICER, THE LOSS OF ANY OF WHOM COULD SERIOUSLY HARM OUR
BUSINESS.

Our future success depends in large part on the continued services of our
senior management and key personnel. In particular, we are highly dependent on
the service of Davidi Gilo, our Chairman and Chief Executive Officer, and
Menashe Shahar, our Chief Technical Officer. We do not carry key person life
insurance on our senior management or key personnel. Any loss of the services of
Davidi Gilo, Menashe Shahar, other members of senior management or other key
personnel could seriously harm our business.

THIRD PARTIES MAY BRING INFRINGEMENT CLAIMS AGAINST US WHICH COULD HARM OUR
ABILITY TO SELL OUR PRODUCTS AND RESULT IN SUBSTANTIAL LIABILITIES.

We expect that we will increasingly be subject to license offers and
infringement claims as the number of products and competitors in our market
grows and the functionality of products overlaps. In this regard, in early 1999,
we received a written notice from Hybrid Networks in which Hybrid claimed to
have patent rights in certain technology. Hybrid requested that we review our
products in light of six of Hybrid's issued patents.

Third parties, including Hybrid, could assert, and it could be found, that
our technologies infringe their proprietary rights. We could incur substantial
costs to defend any litigation, and intellectual property litigation could force
us to do one or more of the following:

- obtain licenses to the infringing technology;

- pay substantial damages under applicable law;

- cease the manufacture, use and sale of infringing products; or

- expend significant resources to develop non-infringing technology.

Accordingly, any infringement claim or litigation against us could significantly
harm our business, operating results and financial condition.

12
<PAGE>
IF WE FAIL TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY, WE MAY NOT BE ABLE
TO COMPETE.

Our success depends in part on our ability to protect our proprietary
technologies. We rely on a combination of patent, copyright and trademark laws,
trade secrets and confidentiality and other contractual provisions to establish
and protect our proprietary rights. Our pending or future patent applications
may not be approved and the claims covered by such applications may be reduced.
If allowed, our patents may not be of sufficient scope or strength, others may
independently develop similar technologies or products, duplicate any of our
products or design around our patents, and the patents may not provide us
competitive advantages. Litigation, which could result in substantial costs and
diversion of effort by us, may also be necessary to enforce any patents issued
or licensed to us or to determine the scope and validity of third-party
proprietary rights. Any such litigation, regardless of outcome, could be
expensive and time consuming, and adverse determinations in any such litigation
could seriously harm our business.

UNDETECTED HARDWARE DEFECTS OR SOFTWARE ERRORS MAY INCREASE OUR COSTS AND IMPAIR
THE MARKET ACCEPTANCE OF OUR SYSTEMS.

Our systems may contain undetected defects or errors. This may result either
from defects in components supplied by third parties or from errors in our
software that we have failed to detect. These defects or errors are likely to be
found from time to time in new or enhanced products and systems after
commencement of commercial shipments. Our customers integrate our systems into
their networks with components from other vendors. Accordingly, when problems
occur in a network system it may be difficult to identify the component that
caused the problem. Regardless of the source of these defects or errors, we will
need to divert the attention of our engineering personnel from our product
development efforts to address the defect or error. We may incur significant
warranty and repair costs related to defects or errors, and we may also be
subject to liability claims for damages related to these defects or errors. The
occurrence of defects or errors, whether caused by our systems or the components
of another vendor, may result in significant customer relations problems and
injury to our reputation and may impair the market acceptance of our systems.

BECAUSE OF OUR LONG PRODUCT DEVELOPMENT PROCESS AND SALES CYCLE, WE MAY INCUR
SUBSTANTIAL EXPENSES WITHOUT ANTICIPATED REVENUES WHICH COULD CAUSE OUR
OPERATING RESULTS TO FLUCTUATE.

A customer's decision to purchase many of our systems typically involves a
significant technical evaluation, formal internal procedures associated with
capital expenditure approvals and testing and acceptance of new systems that
affect key operations. For these and other reasons, the sales cycle associated
with our systems can be lengthy and subject to a number of significant risks
over which we have little or no control. Our next-generation systems are
expected to have even longer sales

13
<PAGE>
cycles and involve demonstrations, field trials and other evaluation periods,
which will further lengthen the sales cycle. Because of the growing sales cycle
and the possibility that we may rely on a concentrated number of customers for
our revenues, our operating results could be seriously harmed if such revenues
do not materialize when anticipated, or at all.

IF WE CHOOSE TO ACQUIRE NEW AND COMPLEMENTARY BUSINESSES, PRODUCTS OR
TECHNOLOGIES, WE MAY NOT BE ABLE TO SUCCESSFULLY INTEGRATE AN ACQUIRED BUSINESS
IN A COST-EFFECTIVE AND NON-DISRUPTIVE MANNER AND REALIZE ANTICIPATED BENEFITS.

We may make investments in complementary companies, products or
technologies. If we acquire a company, we may have difficulty integrating that
company's personnel, operations, products and technologies. These difficulties
may disrupt our ongoing business, distract our management and employees and
increase our expenses. Moreover, the anticipated benefits of any acquisition may
not be realized. Future acquisitions could result in dilutive issuances of
equity securities, the incurrence of debt, contingent liabilities or
amortization expenses related to goodwill and other intangible assets and the
incurrence of large and immediate write-offs, any of which could seriously harm
our business.

IF THE COMMUNICATIONS AND INTERNET INDUSTRIES DO NOT CONTINUE TO GROW AND EVOLVE
IN A MANNER FAVORABLE TO US OR OUR BUSINESS STRATEGY, OUR BUSINESS MAY BE
SERIOUSLY HARMED.

Our future success is dependent upon the continued growth of the
communications industry and, in particular, the Internet. The global
communications and Internet industries are evolving rapidly, and it is difficult
to predict growth rates or future trends in technology development. In addition,
the deregulation, privatization and economic globalization of the worldwide
communications market, that have resulted in increased competition and
escalating demand for new technologies and services, may not continue in a
manner favorable to us or our business strategies. In addition, the growth in
demand for Internet services and the resulting need for high-speed or enhanced
communications products may not continue at its current rate or at all.

WE MAY NEED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE, AND IF WE ARE UNABLE TO
SECURE ADEQUATE FUNDS ON TERMS ACCEPTABLE TO US, WE MAY NOT BE ABLE TO EXECUTE
OUR BUSINESS PLAN.

We expect that the net proceeds from this offering and cash from operations
will be sufficient to meet our working capital and capital expenditure needs for
at least the next 12 months. After that, we may need to raise additional funds
for a number of uses, including:

- expanding research and development programs;

- hiring additional qualified personnel;

14
<PAGE>
- implementing further marketing and sales activities; and

- acquiring complementary technologies or businesses.

We may have to raise funds even sooner in order to fund more rapid
expansion, to respond to competitive pressures or to otherwise respond to
unanticipated requirements. If we raise additional funds through the issuance of
equity or convertible debt securities, the percentage ownership of our existing
stockholders will be reduced. We may not be able to obtain additional funds on
acceptable terms, or at all. If we cannot raise needed funds on acceptable
terms, we may not be able to increase our ongoing operations and complete our
planned expansion, take advantage of acquisition opportunities, develop or
enhance systems or respond to competitive pressures. This potential inability to
raise funds on acceptable terms could seriously harm our business.

GOVERNMENT REGULATION AND INDUSTRY STANDARDS MAY INCREASE OUR COSTS OF DOING
BUSINESS, LIMIT OUR POTENTIAL MARKETS OR REQUIRE CHANGES TO OUR BUSINESS MODEL.

The emergence or evolution of regulations and industry standards for
broadband wireless products, through official standards committees or widespread
use by operators, could require us to modify our systems, which may be expensive
and time-consuming, and to incur substantial compliance costs. Radio frequencies
are subject to extensive regulation under the laws of the United States, foreign
laws and international treaties. Each country has different regulations and
regulatory processes for wireless communications equipment and uses of radio
frequencies. Failure by the regulatory authorities to allocate suitable,
sufficient radio frequencies to potential customers in a timely manner could
result in the delay or loss of potential orders for our systems and seriously
harm our business.

IF WE FAIL TO SUCCESSFULLY ESTABLISH OUR NEW VYYO NAME, OUR BUSINESS COULD BE
SERIOUSLY HARMED.

In January 2000, we changed our name from PhaseCom, Inc. to Vyyo Inc. to
better represent the diversity of our broadband wireless systems. Our new Vyyo
name may cause confusion to current and potential customers, which could
seriously harm our business. We may be unable to enforce rights related to the
Vyyo Inc. name, we may not be free to use the name in all jurisdictions, our use
of the name may be challenged and we may be required to expend significant
resources in defending the use of the name.

RISKS RELATING TO THIS OFFERING

BECAUSE OUR PRINCIPAL STOCKHOLDERS AND MANAGEMENT HAVE THE ABILITY TO CONTROL
STOCKHOLDER VOTES, THE PREMIUM OVER MARKET PRICE THAT AN ACQUIRER MIGHT
OTHERWISE PAY MAY BE REDUCED AND ANY MERGER OR TAKEOVER MAY BE DELAYED.

Upon completion of this offering, our management and ADC Telecommunications
will collectively own approximately 63% of our outstanding common stock. As a
result, these stockholders, acting together, will be able to control the outcome
of all matters submitted for stockholder action, including:

- electing members to our board of directors;

- approving significant change-in-control transactions;

- determining the amount and timing of dividends paid to themselves and to
our public stockholders; and

- controlling our management and operations.

This concentration of ownership may have the effect of impeding a merger,
consolidation, takeover or other business consolidation involving us, or
discouraging a potential acquirer from making a tender offer for our shares.
This concentration of ownership could also negatively affect our stock's market
price or decrease any premium over market price that an acquirer might otherwise
pay.

BECAUSE THE NASDAQ NATIONAL MARKET IS LIKELY TO CONTINUE TO EXPERIENCE EXTREME
PRICE AND VOLUME FLUCTUATIONS, THE PRICE OF OUR STOCK MAY DECLINE.

The market price of our shares is likely to be highly volatile and could be
subject to wide fluctuations in response to numerous factors, including the
following:

- actual or anticipated variations in our quarterly operating results or
those of our competitors;

- announcements by us or our competitors of new products or technological
innovations;

- introduction and adoption of new industry standards;

- changes in financial estimates or recommendations by securities analysts;

- changes in the market valuations of our competitors;

- announcements by us or our competitors of significant acquisitions or
partnerships; and

- sales of our common stock.

Many of these factors are beyond our control and may negatively impact the
market price of our common stock, regardless of our performance. In addition,
the stock market in general, and the market for technology companies in
particular, has been highly volatile. Our common stock may not trade at the same
levels of shares as

16
<PAGE>
that of other technology companies and shares of technology companies, in
general, may not sustain their current market prices. 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. We may be the
target of similar litigation in the future. Securities litigation could result
in substantial costs and divert management's attention and resources, which
could seriously harm our business and operating results.

OUR MANAGEMENT HAS BROAD DISCRETION IN USING THE PROCEEDS FROM THIS OFFERING,
WHICH MIGHT NOT BE USED IN WAYS THAT IMPROVE OUR OPERATING RESULTS OR INCREASE
OUR MARKET VALUE.

Our management will have broad discretion as to how the net proceeds of this
offering will be used, including uses which may not improve our operating
results or increase our market value. Investors will be relying on the judgment
of management regarding the application of the proceeds of this offering. The
results and the effectiveness of the application of the proceeds are uncertain
and you will not have the opportunity, as part of your investment decision, to
assess whether the proceeds are being used appropriately.

PROVISIONS OF OUR GOVERNING DOCUMENTS AND DELAWARE LAW COULD DISCOURAGE
ACQUISITION PROPOSALS OR DELAY A CHANGE IN CONTROL.

Upon the closing of this offering, our certificate of incorporation and
bylaws will be amended and restated. Our amended and restated certificate of
incorporation and bylaws will contain anti-takeover provisions that could make
it more difficult for a third party to acquire control of us, even if that
change in control would be beneficial to stockholders. Specifically:

- our board of directors will have the authority to issue common stock and
preferred stock and to determine the price, rights and preferences of any
new series of preferred stock without stockholder approval;

- our board of directors will be divided into three classes, each serving
three-year terms;

- super-majority voting will be required to amend key provisions of our
certificate of incorporation and by-laws;

- there will be limitations on who can call special meetings of
stockholders;

- stockholders will not be able take action by written consent; and

- advance notice will be required for nominations of directors and for
stockholder proposals.

In addition, provisions of Delaware law and our stock option plans may also
discourage, delay or prevent a change of control or unsolicited acquisition
proposals.

17
<PAGE>
FUTURE SALES OF OUR COMMON STOCK COULD DEPRESS OUR STOCK PRICE.

We cannot predict if future sales of our common stock, or the availability
of our common stock for sale, will depress the market price for our common stock
or our ability to raise capital by offering equity securities. Sales of
substantial amounts of common stock, or the perception that these sales could
occur, may depress prevailing market prices for the common stock.

After this offering, approximately 33,697,286 shares of common stock will be
outstanding, based on shares outstanding as of December 31, 1999. All of the
shares sold in this offering will be freely tradeable except for any shares
purchased by affiliates of Vyyo. The remaining shares of common stock
outstanding after this offering will be restricted as a result of securities
laws or lock-up agreements. These remaining shares will be available for sale in
the public market as follows:

Banc of America Securities LLC may release all or a portion of the shares

WE MAY HAVE CONTINGENT LIABILITY ARISING IN CONNECTION WITH OUR PRESS RELEASE
OUT OF A POSSIBLE VIOLATION OF SECTION 5 UNDER THE SECURITIES ACT.

We issued a press release that announced the initial filing with the
Securities and Exchange Commission of a registration statement relating to this
offering. This press release also contained information regarding Vyyo. If the
press release were determined to have constituted a prospectus that did not meet
the requirements of Section 5 and Section 10 of the Securities Act, which would
be a violation of the Securities Act, then purchasers in this offering could
have the right, for a period of one year from the date of their purchase, to
bring an action for rescission or for damages resulting from their purchase of
our common stock. We believe that this right, if any, would be limited to
purchasers that viewed this press release, but we cannot assure this to be the
case. We do not believe that the existence of this press release caused a
violation of the Securities Act. Accordingly, we do not believe that our
exposure, if any, resulting from this press release will be material to our
results of operations or financial condition.

RISKS RELATING TO OUR LOCATION IN ISRAEL

CONDITIONS IN ISRAEL AFFECT OUR OPERATIONS AND MAY LIMIT OUR ABILITY TO PRODUCE
AND SELL OUR SYSTEMS.

Our final testing and assembly and research and development facilities are
located in Israel. Political, economic and military conditions in Israel
directly affect our operations. Since the establishment of the State of Israel
in 1948, a number of armed conflicts have taken place between Israel and its
Arab neighbors and a state of hostility, varying in degree and intensity, has
led to security and economic problems for Israel. We could be adversely affected
by any major hostilities involving Israel, the interruption or curtailment of
trade between Israel and its trading partners, a significant increase in
inflation, or a significant downturn in the economic or financial condition of
Israel. Despite the progress towards peace between Israel and its Arab
neighbors, the future of these peace efforts is uncertain. Moreover, several
countries still restrict business with Israel and with Israeli companies. We
could be adversely affected by restrictive laws or policies directed towards
Israel or Israeli businesses.

Some of our directors, officers and employees are currently obligated to
perform annual reserve duty and are subject to being called to active duty at
any time under emergency circumstances. Our business cannot assess the full
impact of these requirements on our workforce or business if conditions should
change and we cannot predict the effect on us of any expansion or reduction of
these obligations.

BECAUSE SUBSTANTIALLY ALL OF OUR REVENUES ARE GENERATED IN U.S. DOLLARS WHILE A
PORTION OF OUR EXPENSES ARE INCURRED IN NEW ISRAELI SHEKELS, OUR RESULTS OF
OPERATIONS MAY BE SERIOUSLY HARMED IF THE RATE OF INFLATION IN ISRAEL EXCEEDS
THE RATE OF DEVALUATION OF THE NEW ISRAELI SHEKEL AGAINST THE U.S. DOLLAR.

We generate substantially all of our revenues in U.S. dollars, but we incur
a substantial portion of our expenses, principally salaries and related
personnel expenses related to research and development, in New Israeli shekels,
or NIS. As a result, we are exposed to the risk that the rate of inflation in
Israel will exceed the rate of devaluation of the NIS in relation to the dollar
or that the timing of this devaluation lags behind inflation in Israel. If the
dollar costs of our operations in Israel increase, our dollar-measured results
of operations will be seriously harmed.

THE GOVERNMENT PROGRAMS AND BENEFITS WE RECEIVE REQUIRE US TO SATISFY PRESCRIBED
CONDITIONS. THESE PROGRAMS AND BENEFITS MAY BE TERMINATED OR REDUCED IN THE
FUTURE, WHICH WOULD INCREASE OUR COSTS AND TAXES AND COULD SERIOUSLY HARM OUR
BUSINESS.

Several of our capital investments have been granted "approved enterprise"
status under Israeli law providing us with tax benefits. The benefits available
to an approved enterprise are conditioned upon the fulfillment of conditions
stipulated in applicable law and in the specific certificate of approval. If we
fail to comply with these conditions, in whole or in part, we may be required to
pay additional taxes for the period in which we benefitted from the tax benefits
and would likely be denied

19
<PAGE>
these benefits in the future. From time to time, the Government of Israel has
discussed reducing or eliminating the benefits available under the approved
enterprise program. These tax benefits may not be continued in the future at
their current levels or at all. This termination or reduction of these benefits
would increase our taxes and could seriously harm our business.

In the past, we received grants from the government of Israel for the
financing of a portion of our research and development expenditures in Israel.
The regulations under which we received these grants restrict our ability to
manufacture products or transfer technology outside of Israel for products
developed with this technology. We believe that most of our current products are
not based on Chief Scientist funded technology and therefore are not subject to
this restriction.

IT MAY BE DIFFICULT TO ENFORCE A U.S. JUDGMENT AGAINST US AND OUR NONRESIDENT
OFFICERS, DIRECTORS AND EXPERTS.

Our Chief Technology Officer, one of our directors and some of the experts
named in this prospectus are nonresidents of the United States, and a
substantial portion of our assets and the assets of these persons are located
outside the United States. Therefore, it may be difficult to enforce a judgment
obtained in the United States based upon the civil liabilities provisions of the
United States federal securities laws against us or any of those persons or to
effect service of process upon these persons in the United States.

CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS

Some of the matters discussed under the captions "Prospectus Summary," "Risk
Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations," "Business" and elsewhere in this prospectus include
forward-looking statements. We have based these forward-looking statements on
our current expectations and projections about future events, including, among
other things:

- implementing our business strategy;

- attracting and retaining customers and employees;

- obtaining and expanding market acceptance of the products we offer and
developing new products;

- forecasts of Internet usage and the size and growth of relevant markets;

- rapid technological changes in our industry and relevant markets; and

- competition in our market.

In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "should," "could," "predicts," "potential," "continue,"
"expects," "anticipates," "future," "intends," "plans," "believes," "estimates"
and similar expressions. These statements are based on our current beliefs,
expectations and assumptions and are subject to a number of risks and
uncertainties. Actual results, levels of activity, performance, achievements and
events may vary significantly from those implied by the forward-looking
statements. A description of risks that could cause our results to vary appears
under the caption "Risk Factors" and elsewhere in this prospectus.

<PAGE>
USE OF PROCEEDS

We estimate that we will receive net proceeds from the sale of shares of our
common stock in this offering of approximately $83.1 million, or $95.9 million
if the underwriters exercise their over-allotment option in full, based upon the
offering price of $13.50 per share, after deducting underwriting discounts and
commissions and estimated offering expenses. The principal purposes of this
offering are to obtain additional capital and to create a public market for our
common stock. We expect to use the net proceeds from this offering for working
capital and other general corporate purposes, including research and
development. In particular, we expect to spend between $9 million and
$12 million on research and development activities in 2000. We may also use a
portion of the net proceeds to acquire complementary products, technologies, or
businesses; however, we currently have no commitments or agreements relating to
any such transactions.

We will have significant discretion in the use of the net proceeds of this
offering. Investors will be relying on the judgment of our management regarding
the application of the proceeds of this offering. Pending use of the net
proceeds as discussed above, we intend to invest these funds in short-term,
interest-bearing, investment-grade obligations.

DIVIDEND POLICY

We have never declared or paid any dividends on our capital stock. We intend
to retain any future earnings to fund the development and expansion our
business. Therefore, we do not anticipate paying cash dividends on our common
stock in the foreseeable future. Through our subsidiary, Vyyo Ltd., we
participate in the "alternative benefits program" under the Israeli law for the
Encouragement of Capital Investments, 1959, under which we realize certain tax
exemptions. If Vyyo Ltd. distributes a cash dividend to Vyyo Inc. from income
which is tax exempt, it would have to pay corporate tax at the rate of up to 25%
on an amount equal to the amount distributed and the corporate tax which would
have been due in the absence of the tax exemption.

DILUTION

Our pro forma net tangible book value as of December 31, 1999 was
approximately $1.3 million, or $0.05 per share of common stock. Pro forma net
tangible book value per share represents the amount of total tangible assets
less total liabilities, divided by 26,947,286, the number of shares of common
stock treated as outstanding on a pro forma basis after giving effect to the
conversion of the preferred stock. After giving effect to the sale of the shares
of common stock offered in this offering at the public offering price of $13.50
per share, after deducting the underwriting discounts and commissions and
estimated offering expenses, our pro forma net tangible book value at
December 31, 1999 would have been $84.5 million, or $2.51 per share. This
represents an immediate increase in net pro forma tangible book value to
existing stockholders of $2.46 per share and an immediate dilution of
$10.99 per share to new investors. The following table illustrates the per share
dilution:

The following table summarizes on a pro forma basis, after giving effect to
the conversion of the preferred stock, the total number of shares of common
stock purchased from us, the total consideration paid to us and the average
price per share paid by existing stockholders and by new investors, in each case
based upon the number of shares of common stock outstanding as of December 31,
1999.

</TABLE>

If the underwriters' over-allotment is exercised in full, the percentage of
shares of common stock held by existing stockholders will be reduced to 77.6% of
the total number of shares of common stock to be outstanding after this offering
and the number of shares of common stock held by new investors will increase to
7,762,500, or 22.4% of the total number of shares of common stock to be
outstanding immediately after this offering.

The foregoing discussions and tables assume no exercise of any stock options
or warrants outstanding. There were options outstanding to purchase
3,771,195 shares of common stock as of February 29, 2000 at a weighted average
exercise price of $0.83 per share, 801,958 shares of common stock issued from
January 1, 2000 through February 29, 2000 upon the exercise of stock options
issued under our option plans, 5,119,189 shares of common stock reserved for
issuance under our stock option and purchase plans, and warrants outstanding to
purchase 187,785 shares of common stock at a weighted average exercise price of
$1.26 per share. To the extent that any of these options or warrants are
exercised, there will be further dilution to the new investors.

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

OVERVIEW

We supply broadband wireless access systems used by telecommunications
service providers to deliver wireless, high-speed data connections to business
and residential subscribers. We sell our systems directly to service providers,
as well as to system integrators that deploy our systems as part of their
end-to-end network solutions for service providers. We have incurred significant
losses since our inception, and we expect to continue to incur net losses for
the foreseeable future. We incurred net losses of approximately $43.6 million
for the year ended December 31, 1999. As of December 31, 1999, our accumulated
deficit was approximately $66.2 million.

We were incorporated in 1996 in Delaware and succeeded to the business of
Vyyo Ltd., formerly PhaseCom Ltd., an Israeli company, under a reorganization.
As a result, Vyyo Ltd. became our wholly-owned subsidiary. Prior to our
introduction of broadband wireless access systems, we developed and marketed
cable broadband communication systems. Our first-generation broadband wireless
system was commercially deployed during the first quarter of 1999 for the local
multipoint distribution system, or LMDS, and the multichannel multipoint
distribution system, or MMDS, frequency bands. Our second-generation,
DOCSIS-based, broadband wireless access system was commercially deployed during
the first quarter of 2000 for the LMDS and MMDS frequency bands. Our
first-generation broadband wireless access system has been commercially deployed
at 21 domestic and international sites and our second-generation system has been
commercially deployed at one domestic site.

RESULTS OF OPERATIONS

NET REVENUES. Net revenues include product revenues and, in 1999,
technology development revenues. Product revenues are derived primarily from
sales of hubs and modems to telecommunications service providers and to system
integrators. Product revenues are generally recorded when products are shipped,
provided there are no customer acceptance requirements and we have no additional
performance obligations. We accrue for estimated sales returns or exchanges and
product warranty and liability costs upon recognition of product revenues.
Technology development revenues consist of license fees paid by Philips
Semiconductor under a license and development agreement, and are recognized when
the applicable customer milestones are met, including deliverables, but not in
excess of the estimated amount that would be recognized using the
percentage-of-completion method. We expect to complete this arrangement in 2000
and no other similar arrangements are contemplated. Deferred revenues represent
the gross profit on product revenues subject to return or exchange and total
payments on technology development not yet recognized.

26
<PAGE>
In 1999, approximately 61% of our revenues were derived from customers in
North America, 22% from customers in Europe, 13% from customers in Asia and 4%
from other regions.

Our revenue is concentrated among relatively few customers. In 1999, four
customers collectively represented approximately 59% of our net revenues. In
1999, revenues from each of four customers represented approximately 20%, 14%,
13% and 12% of net revenues. In 1998, revenues from each of three customers
represented approximately 31%, 23% and 15% of net revenues. In 1997, revenue
from each of three customers represented approximately 27%, 12% and 11% of total
revenues. Though our principal revenue-generating customers are likely to vary
on a quarterly basis, we anticipate that our revenues will remain concentrated
among a few customers for the foreseeable future. In August 1999, ADC
Telecommunications, Inc., one of our major customers, made an approximately 10%
equity investment in Vyyo.

Net revenues increased 59% from $1.5 million in 1997 to $2.4 million in 1998
and 73% to $4.2 million in 1999. This increase primarily reflects the increase
in unit sales of our systems in 1998 and 1999 and the technology development
activities in 1999. We began commercial shipments of our first-generation
broadband wireless access system in the first quarter of 1999, and we began
commercial shipments of our second-generation DOCSIS-based wireless access
system in the fourth quarter of 1999. All of our product revenues in 1997 and
1998, and a substantial portion of our product revenues in 1999, relate to sales
of cable modem products that we are no longer developing. Virtually all of the
remaining revenues in 1999 relate to sales of our first-generation wireless
modem products, which we phased out with the launch of our second-generation,
DOCSIS-based, wireless access systems in the fourth quarter of that year.
Therefore, the success of our business will be entirely dependent upon the
success of our wireless products generally, and our new DOCSIS-based wireless
products in particular. We do not anticipate recognizing material amounts of
revenue from cable modem or first-generation wireless products in subsequent
periods. Technology development revenues were $480,000 in 1999. There were no
technology development revenues in either 1997 or 1998.

COST OF REVENUES. Cost of revenues consist of costs of product revenues and
in 1999 included $313,000 of costs of technology development revenues. There
were no costs of technology development revenues in either 1997 or 1998. Cost of
technology development revenues consist of component and material costs, direct
labor costs, warranty costs, royalties in connection with Israeli government
incentive programs and overhead related to manufacturing our products. Cost of
technology development consist of direct labor costs and materials for the
engineering efforts related to the technology development arrangement.

Cost of revenues increased from $1.6 million in 1997 to $2.6 million in 1998
and to $4.3 million in 1999. These increases were attributable primarily to
increased shipments of our products in each of the three years and in 1999
included the technology development activities. Gross margins were negative in
each year. Gross

27
<PAGE>
margins in 1997 and 1998 were negatively affected by the high initial fixed
costs and low volumes associated with our proprietary cable modem products. In
addition, gross margins in 1999 were negatively affected by the high fixed costs
associated with the first generation wireless modem products and inventory
write-offs associated with the discontinuation of in-house cable modem assembly,
as well as the replacement of a modem system for a key customer with
next-generation technology. We expect that our gross margins will continue to
fluctuate.

Prior to 1997, we participated in several Israeli government research and
development incentive programs under which we received research and development
participation of approximately $3.7 million. We are obligated to pay royalties
at rates that generally range from 2.5% to 5% of revenues resulting from the
funded projects up to maximum amounts of 100% or 150% of the funded amount. As
of December 31, 1999, we had repaid or provided for the repayment of grants
amounting to $651,000. As we currently intend to gradually decrease the
manufacture and sale of products developed within any of the projects funded by
the Office of the Chief Scientist in the Israeli Ministry of Industry and Trade
or by the Israel-United States Binational Industrial Research and Development
Foundation, we believe that the remaining contingent royalty liability is
approximately $800,000.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
consist primarily of personnel, facilities, equipment and supplies for our
research and development activities. Substantially all of our research and
development activities are carried out in our facility in Israel. These expenses
are charged to operations as incurred. Our research and development expenses
increased from $2.4 million in 1997 to $3.3 million in 1998 and to $3.7 million
in 1999. These increases were due to increased levels of activities and related
costs of personnel and facilities. We believe significant investment in research
and development is essential to our future success and plan on increasing our
research and development activities. We expect to spend between $9 million and
$12 million on research and development activities in 2000. This includes
recruiting and hiring additional personnel and expanding our research and
development facility to accommodate the additional personnel, which will result
in increased expenses in absolute dollars. Accordingly, we expect that research
and development expenses will continue to increase in future periods.

SALES AND MARKETING EXPENSES. Sales and marketing expenses consist of
salaries and related costs of sales and marketing employees, consulting fees and
expenses for travel, trade shows and promotional activities. Selling and
marketing expenses increased from $1.5 million in 1997 to $2.4 million in 1998
and decreased to $2.0 million in 1999. The fluctuation in sales and marketing
expenses in each of the years was primarily due to changes in the number of
sales and marketing personnel. We plan to increase our sales and marketing
activities, including recruiting and hiring additional senior personnel, which
will result in increased expenses in absolute dollars. Accordingly, we expect
that sales and marketing expenses will increase in future periods.

28
<PAGE>
GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
consist primarily of personnel and related costs for general corporate
functions, including finance, accounting, strategic and business development,
human resources and legal. General and administrative expenses increased from
$1.2 million in 1997 to $1.4 million in 1998 and to $2.1 million in 1999. We
recently hired additional senior management personnel and are planning to expand
operational and corporate activities, including support of our operations as a
public company. We expect that general and administrative expenses will increase
in future periods.

AMORTIZATION OF DEFERRED STOCK COMPENSATION. Deferred stock compensation
represents the aggregate differences between the respective exercise price of
stock options or purchase price of stock at their dates of grant or sale and the
deemed fair market value of our common stock for accounting purposes. Deferred
stock compensation is presented as a reduction of stockholders' equity and is
amortized over the vesting period of the underlying options. Amortization
expense was $9.3 million in 1999. We currently expect to record amortization of
deferred stock compensation expense of approximately $8.1 million in 2000,
$3.3 million in 2001 and $2.0 million thereafter for options issued through
December 31, 1999, and to record additional expenses for options granted
subsequent to that date.

CHARGE FOR AMENDED FINANCING ARRANGEMENT. Charge for amended financing
arrangement represents the aggregate differences between the amended notes
payable conversion price per share or the related amended warrants exercise
price and the deemed fair market value of our common stock for accounting
purposes.

INTEREST INCOME (EXPENSE), NET. Interest income (expense) consists of
interest earned on cash and cash equivalents offset by interest expense related
to bank loans and convertible notes. Net interest expense increased from
($244,000) in 1997 to ($524,000) in 1998 to ($717,000) in 1999 due to increased
borrowings.

INCOME TAXES. As of December 31, 1999, we had approximately $19 million of
Israeli net operating loss carryforwards and $41 million of United States
federal and state net operating loss carryforwards. The Israeli net operating
loss carryforwards have no expiration date and have not been recorded as tax
assets because the losses are expected to be utilized during a tax exempt
period. The United States net operating loss carryforwards expire in various
amounts between the years 2004 and 2019. We have provided a full valuation
allowance against our United States deferred tax assets as the future
realization of the tax benefit is not sufficiently assured.

QUARTERLY RESULTS OF OPERATIONS

The table below sets forth statement of operations data for each of the four
consecutive quarters for the year ended December 31, 1999. This information has
been derived from our unaudited consolidated financial statements. We have
prepared the unaudited consolidated financial statements on the same basis as
our audited consolidated financial statements contained elsewhere in this
prospectus and include

29
<PAGE>
all adjustments, consisting only of normal recurring adjustments, that we
consider necessary for a fair presentation of such information. You should read
this information in conjunction with our consolidated financial statements and
the accompanying notes appearing elsewhere in this prospectus. Our limited
operating history makes the prediction of future operating results difficult or
impossible. We do not believe that period-to-period comparisons of our operating
results are meaningful or should be relied upon as an indication of future
performance.

</TABLE>

Cost of revenues in the third quarter of 1999 reflect approximately $200,000
in inventory write-downs associated with discontinuation of in-house cable modem
production. Operating expenses in the third and fourth quarters of 1999 reflect
higher sales and marketing and general and administrative expenses due primarily
to the general increase in personnel and the increase in sales and marketing and
corporate activities. Our quarterly operating results have varied significantly
in the past and are likely to vary significantly in the future. These variations
result from a number of factors, many of which are beyond our control. In
addition, our operating results may be below the expectations of securities
analysts and investors in future periods. Our failure to meet these expectations
will likely cause our share price to decline.

LIQUIDITY AND CAPITAL RESOURCES

Since our inception, we have funded operations primarily through the private
placement of our equity securities and borrowings from stockholders and banks.
We raised approximately $4.2 million in 1997, $6.8 million in 1998 and
$11.7 million in 1999 in convertible debt from stockholders and equity. As of
December 31, 1999, we had cash and cash equivalents of approximately
$5.0 million.

Cash used by operations include expenditures associated with development
activities and marketing efforts related to commercialization of our products.
In 1999,

30
<PAGE>
cash used in operations was $6.2 million comprised of our net loss of
$43.6 million, increase in accounts receivable of $336,000, partially offset by
non-cash charges of $35 million for deferred stock compensation and amended
financing agreements, a decrease in inventories of $512,000 and increase in
accounts payable and accrued liabilities of $1.5 million. In 1998, cash used in
operations was $6.7 million comprised of our net loss of $7.7 million, increase
in inventory of $638,000, partially offset by a $1.1 million increase in
accounts payable and accrued liabilities. In 1997, cash used in operations was
$4.7 million comprised of our net loss of $5.3 million, increase in inventory of
$639,000, partially offset by a $1.1 million increase in accounts payable and
accrued liabilities.

We have made investments in property and equipment of approximately
$1.3 million in 1997 through 1999.

We have a line of credit arrangement with a bank for an aggregate amount of
$2.5 million. The loans under this line of credit bear interest at a rate of
LIBOR plus 1.5%. At December 31, 1999, the applicable rate was 7.25% per annum.
Borrowings and bank guarantees under the line of credit were $2,280,000 and
$220,000 at December 31, 1999. As of December 31, 1999, all assets of our
Israeli subsidiary are subject to fixed and floating liens pursuant to certain
loan agreements.

Our capital requirements depend on numerous factors, including market
acceptance of our products, the resources we devote to developing, marketing,
selling and supporting our products, the timing and extent of establishing
additional international operations and other factors. We expect to devote
substantial capital resources to hire and expand our research and development
and our sales and marketing organizations, to expand marketing programs and for
other general corporate activities. In particular, we expect to spend between
$9 million and $12 million on research and development activities in 2000. We
expect that the net proceeds from this offering and cash from operations will be
sufficient to meet our working capital and capital expenditure needs for at
least the next 12 months. After that, we may need to raise additional funds for
a number of uses. If we raise additional funds through the issuance of equity or
convertible debt securities, the price paid for such securities may be
substantially less than the price paid for the common stock sold in this
offering and, in any event, the percentage ownership of our existing
stockholders will be reduced. We may not be able to obtain additional funds on
acceptable terms, or at all. If we cannot raise needed funds on acceptable
terms, we may not be able to increase our ongoing operations and complete our
planned expansion, take advantage of acquisition opportunities, develop or
enhance systems or respond to competitive pressures.

EFFECTIVE CORPORATE TAX RATES

Our tax rate will reflect a mix of the United States federal and state tax
on our United States income and Israeli tax on non-exempt income. The majority
of our Israeli subsidiary's income is derived from our company's capital
investment program

31
<PAGE>
with "Approved Enterprise" status under the Law for the Encouragement of Capital
Investments, and is eligible therefore for tax benefits. Because of these
benefits, we will enjoy a tax exemption on income derived from this investment
program for a period of six years commencing in the first year in which the
Israeli subsidiary will have taxable income, provided that we do not distribute
such income as a dividend, and a reduced tax rate of 10 to 15% for up to four
subsequent years. All of these tax benefits are subject to various conditions
and restrictions. There can be no assurance that we will obtain approval for
additional Approved Enterprises Programs or that the provisions of the law will
not change. Since we have incurred tax losses through December 31, 1999, we have
not yet used the tax benefits for which we are eligible.

YEAR 2000 ISSUES

We currently are not aware of any Year 2000 problem in any of our critical
systems and products. However, the success to date of our Year 2000 efforts
cannot guarantee that a Year 2000 problem affecting third parties upon which we
rely will not become apparent in the future, which could harm our business.

RECENT ACCOUNTING PRONOUNCEMENTS

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

DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks including changes in interest rates
and foreign currency exchange rates. As of December 31, 1999, we had cash and
cash equivalents of $5.0 million. Substantially all of these amounts consisted
of checking account cash balances and are therefore not subject to interest rate
risk. Substantially all of our revenue and capital spending is transacted in
U.S. dollars, although a substantial portion of the cost of our operations,
relating mainly to our personnel and facilities in Israel, is incurred in New
Israeli shekels, or NIS. We have not engaged in hedging transactions to reduce
our exposure to fluctuations that may arise from changes in foreign exchange
rates. In the event of an increase in inflation rates in Israel, or if
appreciation of the NIS occurs without a corresponding adjustment in our
dollar-denominated revenues, our results of operation and business could be
materially harmed.

BUSINESS

OVERVIEW

We supply broadband wireless access systems used by telecommunications
service providers to deliver wireless, high-speed data connections to business
and residential subscribers. Our systems are deployed in point-to-multipoint
applications at the radio frequencies licensed for two-way broadband
communication. Point-to-multipoint technology refers to the ability of a
central, wireless hub to transmit and receive network traffic to and from
multiple subscriber modems. Our systems are based on the Internet protocol, or
IP, which is the networking standard used to deliver voice and data over the
Internet. Networking standards are the special set of rules for communicating
that the end points in a telecommunication connection use when they send signals
back and forth. Our system is designed to allow service providers to support
rapid and cost-effective broadband service roll-outs directly to business and
residential subscribers. Service providers use our system to bridge the segment
of the network that connects the service providers' systems directly to the
subscribers, commonly referred to as the last mile.

In recent years, the volume of high-speed data traffic across worldwide
communications networks has grown dramatically as the public Internet and
private corporate intranets have been broadly adopted for communications and
e-commerce. This traffic growth has created demand for cost-effective,
high-speed communications, as subscribers increasingly rely on numerous
applications and data-intensive content, such as full-streaming video where
subscribers watch video clips with sound over the Internet, voice over IP where
subscribers conduct voice calls over the Internet instead of their telephones,
and provide remote access to corporate networks where telecommuters can access
corporate networks from locations other than their offices. In the United States
and abroad, the communications industry is in varying stages of deregulation.
Deregulation has created the opportunity for new competitors to use existing and
emerging broadband technologies to offer multiple communications services
directly to subscribers. There are a number of broadband wire-based technologies
that do not utilize airwaves for data and voice transport, but instead use
copper wire, fiber optic cable, or other physical wires to transport voice and
data. These wire-based technologies deliver high-speed connections, but
performance, cost, time for deployment or service availability may limit the use
of these alternative technologies to satisfy the needs of service providers and
subscribers. Broadband wireless technologies deliver high-speed connections and
offer service providers the ability to rapidly and cost-effectively expand their
subscriber base or to enter new markets while avoiding the limitations of the
existing wire-based infrastructure.

Our system consists of a wireless hub, which serves as a point of
convergence for data traffic in a network, network management system software
and wireless subscriber modems. Each wireless hub is located at a base station,
which houses the components in the network. Our system is designed to allow
service providers to

33
<PAGE>
rapidly deploy cost-effective, high-speed data connections directly to business
and residential subscribers. Each hub transmits and receives network traffic to
and from our wireless modems, which are installed at multiple subscriber
locations. Our integrated network management system, which manages the traffic
over the network, optimizes how quickly and efficiently the system operates by
allocating bandwidth, or the amount of data which can travel over the wireless
signal. These system characteristics allow service providers to maximize the
number of simultaneous subscribers on their networks. Using our
point-to-multipoint system, service providers can roll out network service
quickly and with a minimal initial investment and can then expand their networks
by adding more wireless hubs and subscriber wireless modems as the number of
subscribers grows.

We sell our systems directly to service providers and system integrators,
who provide network planning and integration services and integrate our systems
with other components in the network and provide their customers with end-to-end
network solutions. We also provide system integration services to some of our
service provider customers to more effectively implement our systems. As of
January 31, 2000, our first-generation system had been commercially deployed at
21 domestic and international sites and our second-generation system had been
commercially deployed at one domestic site. Our second-generation systems use
our enhanced version of the cable industry's Data Over Cable Service Integration
Specification, or DOCSIS, standard.

We have applied for federal registration of our trademarks DOCSIS(+) and
LMDS Lite. Other service marks, trademarks and trade names referred to in this
prospectus are the property of their respective owners.

INDUSTRY BACKGROUND

Use of the Internet and private communications networks has expanded and
continues to expand rapidly. International Data Corporation estimates that there
were 142 million Internet subscribers at the end of 1998, and projects that this
number will grow to over 500 million subscribers by 2003. Businesses
increasingly depend upon data networks, not only for communication within the
office, but also to exchange information among corporate sites, remote
locations, telecommuting employees, business partners, suppliers and customers.
Consumers are also accessing the Internet to communicate, collect and publish
information and conduct retail purchases.

The growth in data traffic is resulting in an increase in the demand for
high-speed access. In light of this demand, the FCC has taken steps to increase
the availability of frequencies and bandwidth that may be used by wireless
carriers in the United States for such data transmission. The FCC has increased
the availability of various frequencies within the bands of 24 to 40 Gigahertz,
or GHz, frequencies often referred to as LMDS. In addition, an FCC ruling in
September 1998 allowed license holders of MMDS, or various frequencies within
the band of 2.15 to 2.68 GHz, to offer two-way broadband wireless data services.
Previously, these frequencies had been

34
<PAGE>
restricted to one-way video transmissions. The FCC has also adopted orders to
allocate additional spectrum through auctions during 2000 which can be used by
high-speed data transmission service providers. Opportunities in broadband
wireless access are increasing globally as Europe, Latin America, Asia Pacific
and Canada join the United States in promoting competition in the local
communications services market by allocating frequencies and bandwidth and
issuing transmission licenses. In this regard, at least 26 countries have
allocated broadband wireless frequency bands for use or trials in the last mile,
according to Global Telephony.

Deregulation has been a significant catalyst for increased competition in
the long-haul segment of the market and massive spending on network
infrastructure, as incumbent and emerging carriers have sought to address the
growing demand for bandwidth. In the local access segment of the market,
deregulation has also been a significant catalyst for the growing interest in
providing broadband access directly to subscribers. Data services that
historically were offered only by a single provider for a region now may be
offered by a number of competing service providers. This increased competition
has given local service providers compelling incentives to improve data
transmission rates in order to offer additional value-added services to
subscribers. However, bandwidth limitations of the existing last mile
infrastructure have constrained service providers from exploiting these
opportunities. Last mile links to subscribers typically consist of copper wires
that operate at substantially lower transmission speeds than those offered in
the long-haul segment of a network, or by some available broadband alternatives.
These copper wires were originally intended to carry only analog
circuit-switched, voice signals. As a result, the last mile has become a
bottleneck that limits high-speed data transmission.

Alternative technologies for broadband access include:

- DIGITAL SUBSCRIBER LINE. Digital subscriber line, or DSL, technology
improves the data transmission rates of a telephone company's existing
copper wire network.

- CABLE MODEMS. Cable modems are designed to provide broadband Internet
access and are targeted primarily at the residential market.

- FIBER-BASED SOLUTIONS. Fiber-based solutions and high-capacity leased
lines offer the highest data transmission rate of any of the alternative
technologies for broadband access.

- POINT-TO-POINT WIRELESS TECHNOLOGY. Point-to-point wireless technology
enables data transmission using a dedicated radio link between two
locations.

- BROADBAND POINT-TO-MULTIPOINT WIRELESS TECHNOLOGY. Broadband
point-to-multipoint wireless networks consist of a wireless hub that
communicates over radio frequencies to transmit and receive network
traffic to and from wireless modems installed at multiple subscriber
locations.

35
<PAGE>
Broadband wireless technology is being utilized by both incumbent and
emerging service providers. The established carriers are expected to use
broadband wireless technology to reach new customers to whom they previously
could not provide access, fill coverage gaps in their existing networks and
deploy value-added services in a cost-effective manner. For example,
International Data Corporation reports that in 1999, Sprint and MCI WorldCom
spent over $1.5 billion to purchase companies holding MMDS licenses. Emerging
carriers may use this technology to bypass existing wire-based infrastructure
and to compete with incumbent carriers. In addition, this technology may be used
to deploy broadband services in regions where there is no wire-based
communications infrastructure. International Data Corporation estimates that
revenue generated by basic services delivered via fixed wireless technologies
will grow from $767 million last year to $7.4 billion in 2003.

THE VYYO SOLUTION

Our systems are designed to provide the following benefits:

COST-EFFECTIVENESS. Service providers worldwide are beginning to use
wireless access technologies as a cost-effective alternative to wire-based
communications, such as cable modems and digital subscriber lines. Our wireless
system avoids many of the high costs associated with wire-based solutions, such
as costs of installing copper wire, cable or fiber and obtaining access
rights-of-way and digging up streets to lay wire. We believe that our systems
are more cost-effective than other wireless access systems because our IP-based
systems are easy to operate and less expensive to install and maintain. Our
second-generation systems use our enhanced version of the DOCSIS standard, which
also contributes to cost-effectiveness.

DOCSIS-BASED SYSTEMS. We use our enhanced version of the DOCSIS standard,
which we call DOCSIS(+), in our second-generation wireless access systems.
Because different manufacturers may use different protocols or rules for
communicating and sending signals back and forth in their products, these
products are often unable to communicate with one another or with products from
other manufacturers. By designing systems with communication rules based on the
DOCSIS standard, our systems can be more easily adapted to new standards and
rules and make them easier to integrate with other manufacturers' equipment.
Widely-available key components make our DOCSIS-based systems less expensive to
use than most other currently available systems.

COMMERCIAL DEPLOYMENTS. Our product is one of the first commercially
available wireless hub and modem systems for the multichannel multipoint
distribution system, or MMDS, and local multipoint distribution system, or LMDS,
frequency bands. Our first-generation system has been commercially deployed at
21 domestic and international sites and our second-generation, DOCSIS-based,
system has been commercially deployed at one domestic site.

FLEXIBLE PLATFORM. Our systems are highly scalable which allows additional
users and hubs to be added quickly and easily, so our customers can establish a
wireless broadband access network with a relatively low initial investment and
later expand the geographic coverage area of the network and increase the number
of users who can be served on the network as subscriber demand increases. Our
integrated network management system is designed to allow new system features
and benefits to be added without costly replacements of existing hardware.
Service providers also use the integrated network management system to manage
the traffic over the network and optimize the how quickly and efficiently the
system operates by efficiently allocating bandwidth, or the amount of data which
can travel over the wireless signal. These system characteristics allow service
providers to maximize the number of simultaneous end-users served by a hub while
preserving the speed and quality of data transmission.

STRATEGY

Our objective is to be a leading worldwide supplier to service providers and
system integrators of broadband wireless access systems used in
point-to-multipoint applications. Our strategy to accomplish this objective is
to:

- USE EXISTING COMMERCIALLY DEPLOYED SYSTEMS TO DEMONSTRATE OUR
CAPABILITIES. We intend to use the early acceptance of our systems to
demonstrate our capabilities to potential customers as we seek to expand
our customer base.

- BROADEN OUR PRODUCT OFFERINGS. We intend to develop products with
additional features and benefits and new systems for use in additional
wireless frequency bands worldwide as these frequencies become available.
We expect to make relatively minor modifications in our transmission
components to enable our systems to operate in different frequency bands.
We do not expect to redesign our entire system architecture.

- IMPROVE COST-EFFECTIVENESS AND PERFORMANCE. We intend to continue
improving the performance and quality of our systems, while reducing costs
by integrating advanced components. We are developing additional software
code, which is intended to enhance the functions of the system and
allocate frequencies more efficiently.

- LEVERAGE KEY STRATEGIC RELATIONSHIPS. We have established strategic
relationships with several service providers and system integrators. We
expect to strengthen our existing relationships and establish new
relationships with other system integrators and service providers, to
increase product distribution and expand into additional geographic
markets.

- PARTICIPATE IN DEVELOPING INDUSTRY STANDARDS. We expect that our
technological expertise will allow us to play an integral role in the
development of the wireless DOCSIS standard. In this regard, we are
participating in the Institute of Electrical and Electronic Engineers, or
IEEE, subcommittee to develop wireless industry standards.

PRODUCTS

Our systems are deployed in point-to-multipoint applications at the
frequencies licensed for these applications. Our system is comprised of wireless
hubs and wireless subscriber modems.

The following diagram depicts our broadband wireless access system:

[The graphic is a base station connected to an antenna that transmits to a modem
located in residences and businesses.]

- Point-to-multipoint wireless hubs are located in base stations and send
and receive data traffic to and from up to 8,000 wireless subscriber
modems at very high speeds. Our network management system manages and
controls the traffic transmitted over our broadband wireless system.

- Our wireless modems connected to PCs or LANs are located in residences,
small/home offices, and medium-sized businesses. These modems send and
receive data traffic and provide access to the Internet.

- Our wireless hub interfaces with a router located in the base station that
sends data traffic to the Internet and, in the future, will send voice
traffic to the gateway that connects with the public telephone network.

- System integrators or service providers add additional network equipment,
such as antennae to transmit wireless radio frequency signals, and
complete the network infrastructure.

WIRELESS HUB. Our wireless hub manages data communications between wireless
modems located at subscribers' locations and network devices such as routers
located at a central office or base station. The primary role of the wireless
hub is to manage

38
<PAGE>
the upstream traffic from the subscriber toward the public telephone and data
networks, and the downstream traffic from the networks toward the subscriber.
Our wireless hub can support up to 8,000 wireless modems.

Our wireless hub employs a unique open physical layer architecture that
allows us to easily replace the circuit boards in the hub as more sophisticated
technology becomes available. Our wireless hub is designed to support a variety
of channel capacities by using any combination of six upstream receivers and
four downstream transmitters. For example, our system can provide, among other
combinations, 60 upstream channels and 8 downstream channels or 48 upstream
channels and 16 downstream channels. A channel is a subdivision of a frequency
band used to transmit radio frequency signals. This flexibility allows the
system engineer to configure a system for each specific situation. Several
frequency bands may be used within the same wireless hub.

Our wireless hub may be accessed for modification or transmitter or receiver
module replacement by the operator while maintaining continuous operation. Most
of the modules are identical, which is intended to reduce maintenance and
inventory requirements. When used in combination with our wireless modems, our
wireless hub enables radio frequency performance in any of the currently
licensed point-to-multipoint frequency bands. Multiple wireless hubs may be
controlled through the same network management system operator interface, either
locally or from a remote location.

Our integrated network management system is a Windows NT-based software
package that manages overall system operations. The system features graphical
views of all parts of the network, subscribers, modems and traffic patterns. The
network management system allows network operators to configure, maintain and
troubleshoot hubs and modems from a central workstation. Our network management
system also enables the network operator to work at a location remote from the
public telephone network or the data network, thereby increasing the system's
operational flexibility. In addition, our systems can adjust automatically to
more efficiently utilize available bandwidth. This utilization can translate
into increased potential revenue for service providers as compared to other
currently available wireless products.

WIRELESS MODEM. Our wireless subscriber modem is suitable for residential,
home office or small office deployment. It supports up to 15 individual users
simultaneously through a separate Ethernet hub or switch.

We introduced our first-generation broadband wireless access system during
the third quarter of 1998, for the LMDS frequency band, and during the first
quarter of 1999, for the MMDS frequency band. We introduced our
second-generation broadband wireless access system during the fourth quarter of
1999, for the MMDS and LMDS frequency bands. Currently, the primary frequency
bands for broadband

39
<PAGE>
data services in the United States or other countries are various frequencies
within these bands:

- WCS--Wireless Communications Service--2.305 to 2.320 GHz and 2.345 to
2.360 GHz;

- MMDS--Multichannel Multipoint Distribution Service--2.150 to 2.680 GHz;
and

- LMDS--Local Multipoint Distribution Service--24 to 40 GHz.

We began commercial shipments of our first-generation broadband wireless
access system in the first quarter of 1999, and we began commercial shipment of
our second-generation, DOCSIS-based, wireless access system in the fourth
quarter of 1999. All of our product revenues in 1997 and 1998, and a substantial
portion of our product revenues in 1999, relate to sales of cable modem products
that we are no longer developing. Virtually all of the remaining revenues in
1999 relate to sales of our first-generation wireless modem products, which we
phased out with the launch of our second-generation, DOCSIS-based, wireless
access systems in the fourth quarter of that year. Therefore, the success of our
business will be entirely dependent upon the success of our wireless products
generally, and our new DOCSIS-based wireless products in particular.

TECHNOLOGY

Our experience in designing shared bandwidth communications systems using
time division multiple access technology is the foundation of our expertise in
the point-to-multipoint broadband wireless access market. "Time division
multiple access" is a wireless technology that allows multiple users to share
available bandwidth. We believe that we have extensive expertise in system
design, as well as modem and broadband radio frequency technology. We have
developed media access controller, or MAC, layer algorithms, or software code,
that maximize the number of subscribers that can share a single upstream
channel.

INTERNET PROTOCOL EXPERTISE. Our system architecture supports Internet
Protocol communications traffic, and our primary systems component, the media
access controller, is optimized for Internet Protocol communications traffic. We
have designed our systems to support variable-length Internet Protocol packets,
which carry the data being transmitted, including the most common packet size of
64 bytes.

DOCSIS(+) STANDARD. Our second-generation systems are based on the cable
industry's DOCSIS standard that we have adapted and enhanced for use in the
wireless environment. Our DOCSIS(+) standard provides for comprehensive support
of all Internet Protocol-based services. We believe that we are the first
company to modify the DOCSIS standard to suit the wireless environment. We have
developed media access controller layer algorithms, or software code, based on
DOCSIS(+) for our

40
<PAGE>
wireless hubs and modems and have made additional enhancements to facilitate
reliable communication over the MMDS and LMDS frequency bands.

ENHANCED MAC LAYER ALGORITHMS. Our enhanced media access controller layer
software code, combined with select physical layer software code, provide robust
performance under adverse conditions and effectively utilize the limited
frequency and bandwidth allocations of the MMDS band.

SIGNAL PROCESSING TECHNOLOGY. We develop, deploy and support the networking
architecture for the multiple modules required in our systems. Specifically, we
have developed technology that is designed to correct transmission errors and
prevent unauthorized access to the data being transmitted. We believe that our
ability to rapidly develop and integrate such modules into our systems provides
us with a competitive advantage.

SCHEDULING ALGORITHMS. We develop scheduling software code for time
division multiple access-based point-to-multipoint systems. Our network
management system is designed to predict user behavior and automatically adjust
allocation of frequencies to more efficiently utilize bandwidth. The ability to
control and modify the characteristics of the network management system allows
us to further optimize them for changing environments and future services.

CUSTOMERS

We sell our systems directly to service providers and system integrators
that deploy our systems as part of their end-to-end network solutions for
service providers. We also provide system integration services to some of our
service provider customers to more effectively implement our systems. We sell
our systems based on individual purchase orders. Our customers are not obligated
by long-term contracts to purchase our systems. Our customers can generally
cancel or reschedule orders upon short notice and can discontinue using our
systems at any time.

COLLABORATION AGREEMENT. In August 1999, we entered into a collaboration
agreement with ADC Telecommunications, under which we agreed to sell our hubs
and modems to ADC for resale and distribution to ADC's customers at a market
price to be established by good faith negotiation between ADC and us. Under this
agreement, ADC has the exclusive right to market, sell and distribute our
products to MCI WorldCom, Sprint, BellSouth, Wireless One and Irish Multi
Channel. We also

41
<PAGE>
agreed to grant to ADC a non-exclusive license to use specified software
embedded in or provided with our products.

In connection with the collaboration agreement, ADC made about a 10% equity
investment in Vyyo. Additional information regarding ADC's investment is
contained in this prospectus under the heading "Certain Relationships and
Related Transactions."

LICENSE AND DEVELOPMENT AGREEMENT. In December 1999, we entered into a
license and development agreement with Philips Semiconductor relating to cable
modem systems. Under this contract, we agreed to license two versions of our
DOCSIS MAC system to Philips. We have given Philips a non-exclusive,
royalty-free right to use our DOCSIS 1.0 MAC in exchange for a one-time license
fee. In addition, we have given Philips a non-exclusive, royalty-bearing right
to use our DOCSIS 1.1 MAC in exchange for a license fee, a percentage of which
is paid upon the achievement of specified milestones related to the development
of the DOCSIS 1.1 MAC.

SALES AND MARKETING

The global telecommunications industry is dominated by a limited number of
network system integrators. We focus our marketing efforts on network system
integrators that have the means to provide vendor financing in situations where
our equipment is purchased as part of the total network. For some service
providers, this financing is a necessary part of the total network solution. We
support our system integrator customers with site demonstrations for their
service provider customers. The objective of a site demonstration is to promote
the adoption of our systems for deployment within the service provider's
network.

We also sell our systems directly to service providers. In determining which
accounts to service directly, we focus on those service providers that prefer to
work with a vendor directly and serve as their own system integrator. In some
instances, we may serve as a system integrator and provide, through third
parties, the other components of the network system.

Our direct sales force maintains contact with the service provider and the
system integrator account team, regardless of the actual distribution channel.
This contact keeps us informed of the evolving needs of the service providers
and helps strengthen our relationship with each customer. In some markets, we
have established distribution relationships with local resellers that also
provide support and maintenance to their service provider customers.

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

42
<PAGE>
Our marketing group is also responsible for product management activities
throughout each product's lifecycle. These activities include the definition of
product features, approval of product releases, specification of enhancements to
our product and service offerings, and determination of future product
platforms.

MANUFACTURING

We outsource manufacturing to contract manufacturers that have the expertise
and ability to reduce costs associated with volume manufacturing and to respond
quickly to customer orders while maintaining high quality standards. We
outsource printed circuit board assembly and manufacturing of our wireless hubs
to contract manufacturers located in Israel. We outsource manufacturing of our
wireless modems to a contract manufacturer located in Taiwan. Any inability of
these manufacturers to provide the necessary capacity or output could result in
significant production delays which could harm our business. Our wireless hubs
and modems are currently purchased on a purchase order basis. We have no
guaranteed supply or long-term contractual agreements with any of our suppliers.
In addition, some of the components included in our systems are obtained from a
single source or limited group of suppliers. The partial or complete loss of
such suppliers could increase our costs, delay shipments or require redesigns of
our products.

We assemble our wireless hubs and perform final tests on our systems at our
facility located in Jerusalem, Israel. Our facility is ISO 9002-certified. ISO
9002 is a set of international quality assurance standards for companies
involved in the design, development, manufacturing, installation and servicing
of products or services. These standards are set by the International
Organization for Standardization, or ISO, an international federation of
national standards bodies. To be recommended for ISO 9002 certification, a
company must be audited by an ISO-accredited auditing company and must meet or
surpass ISO standards.

RESEARCH AND DEVELOPMENT

The goal of our research and development activities is to continue the
development and introduction of next-generation products for our customers. Our
efforts are also focused on reducing the cost and increasing the functionality
of our systems, while adapting them to the frequency and interface
specifications required for new markets. Our ongoing new product development
program assesses service providers' needs and technological changes in the
communications market. We are pursuing new generations of many of our products,
including our second-generation system for MMDS frequencies, our
second-generation system for LMDS frequencies and high-capacity,
third-generation wireless hubs for LMDS frequencies.

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

43
<PAGE>
Our future success depends on our continued investment in research and
development in radio, networking and software technologies, and we expect to
continue to invest a significant portion of revenues in this area. Our research
and development expenditures were $2.4 million for 1997, $3.3 million for 1998
and $3.7 million for 1999. We are currently investing significant resources to
enhance our network management system software, integrate base station
components and extend the capabilities, frequencies and transmission capacity of
our systems.

As of December 31, 1999, our research and development staff consisted of 53
employees, all of whom are located in Israel.

COMPETITION

The market for broadband wireless access systems is intensely competitive,
rapidly evolving and subject to rapid technological change. The principal
competitive factors in this market include:

- product performance and features;

- price of competitive products;

- reliability and stability of operation;

- ability to develop and implement new services and technologies;

- ability to support newly allocated frequencies; and

- sales capability, technical support and service.

The primary competing alternative technologies for broadband access include:

DIGITAL SUBSCRIBER LINE. Digital subscriber line, or DSL, technology today
transmits data approximately 50 times faster than a conventional dial-up modem
using the existing copper wire network. DSL transmission rates are limited,
however, by the length and quality of the available copper wires. Various
implementations of DSL are being developed and deployed. Service providers
deploying DSL technology include incumbent local exchange carriers, such as SBC
Communications, Inc. and Bell Atlantic Corporation, as well as numerous
competitive local exchange carriers.

CABLE MODEMS. Cable modems are designed to provide broadband Internet
access and are targeted primarily at the residential market. Cable lines pass by
100 million homes in North America, but only a portion of those homes currently
have access to two-way cable modem service. Several cable companies are
currently offering broadband access services across two-way cable, including
Excite@Home and Time Warner. In addition, we believe that as a result of AT&T's
recent acquisition of Tele-Communications, Inc. and the proposed merger of
America Online, Inc. and Time Warner, cable TV networks will be used
increasingly for voice and high-speed data services.

FIBER-BASED SOLUTIONS. Fiber-based solutions and high-capacity leased lines
offer the highest data transmission rate of any of the alternative technologies
for broadband access. Fiber optic cables use pulses of light to transmit digital
information. Because

44
<PAGE>
fiber optic cables support thousands of high-speed, local digital connections
onto a single higher-speed connection to the central office or the central side
of the cable TV network where all the video signals emanate, they offer
virtually unlimited bandwidth capacity. Due to their high capacity, fiber optic
cables are increasingly being used in the access network in both
telecommunications and cable TV applications. However, these solutions are
costly to deploy for small business and residential subscribers.

DSL and cable modem technologies offer data transmission speeds comparable
to our broadband wireless technology at comparable modem costs. Fiber optic
cable provides faster transmission rates than our broadband wireless technology,
though at significantly higher costs.

Many of our competitors and potential competitors have substantially greater
financial, technical, distribution, marketing and other resources than we have
and, therefore, may be able to respond more quickly to new or changing
opportunities, technologies and other developments. In addition, many of our
competitors have longer operating histories, greater name recognition and
established relationships with system integrators and service providers. These
competitors may also be able to undertake more extensive marketing campaigns,
adopt more aggressive pricing policies and devote substantially more resources
to developing new products. Our primary competitor is Hybrid Networks, Inc. In
addition, well-capitalized companies such as Cisco Systems, Lucent Technologies,
Nortel Networks, Newbridge Networks and other vendors have announced plans to
enter, or are potential entrants into, the broadband wireless market. These
vendors have been attracted by recent investments by MCI WorldCom, Sprint and
other service providers in wireless operations. Most of these competitors have
existing relationships with one or more of our prospective customers. We may not
be able to compete successfully against our current and future competitors and
competitive pressures may seriously harm our business.

GOVERNMENT REGULATION

Our business is premised on the availability of certain radio frequencies
for broadband two-way communications. Radio frequencies are subject to extensive
regulation under the laws of the United States, foreign laws and international
treaties. Each country has different regulation and regulatory processes for
wireless communications equipment and uses of radio frequencies. The regulatory
environment in which we operate is subject to significant change, the results
and timing of which are uncertain. Historically, in many countries the
unavailability of radio frequencies for two-way broadband communications has
inhibited the growth of such networks. The process of establishing new
regulations for broadband wireless frequencies and allocating such frequencies
to operators is complex and lengthy. Our customers and potential customers may
not be able to obtain sufficient frequencies for their planned uses of our
systems. Failure by the regulatory authorities to allocate suitable, sufficient
radio frequencies for such uses in a timely manner could deter potential
customers from ordering our systems and seriously harm our business.

45
<PAGE>
Our systems must conform to a variety of domestic, foreign and international
regulatory requirements established to, among other things, avoid interference
among users of radio frequencies and permit interconnection of equipment.
Regulatory bodies worldwide have adopted and are adopting or revising standards
for wireless communications products. The emergence or evolution of regulations
and industry standards for broadband wireless products, through official
standards committees or widespread use by operators, could require us to modify
our systems, which may be expensive and time-consuming, and incur substantial
compliance costs and seriously harm our business.

We are subject to export control laws and regulations with respect to all of
our products and technology. We are subject to the risk that more stringent
export control requirements could be imposed in the future on product classes
that include products exported by us, which would result in additional
compliance burdens and could impair the enforceability of our contract rights.
Some of our products contain encryption technologies to enable the transfer of
data in a manner that preserves the privacy of the parties communicating such
data. United States law requires that we obtain an export license for our
systems and that we comply with various restrictions on exporting our systems to
certain countries. Our United States license expires October 31, 2000. Under
Israeli Law, means of encryption and encryption equipment are controlled
commodities within the meaning of the Control of Commodities and Services Law,
5718-1957, and are therefore subject to the prohibitions, restraints,
supervision and control governing it by virtue of such law and regulations and
orders thereunder. Such law and regulation prohibit the engagement in means of
encryption otherwise than pursuant to a license from the authorized person
appointed by the Minister of Defense. Vyyo Ltd.'s license to engage in
encryption expires on February 28, 2001. We may not be able to renew these
licenses as necessary from time to time. In addition, we may be required to
apply for additional licenses to cover modifications and enhancements to our
products. Any revocation or expiration of any requisite license, the failure to
obtain a license for product modifications, or more stringent export control
requirements could seriously harm our business.

INTELLECTUAL PROPERTY

We have 16 patent applications pending in the United States. We rely on a
combination of patent, copyright and trademark laws, trade secrets and
confidentiality and other contractual provisions to establish and protect our
proprietary rights, each of which is important to our business.

Our success depends in part on our ability to protect our proprietary
technologies. Our pending or future patent applications may not be approved and
the claims covered by such applications may be reduced. If allowed, our patents
may not be of sufficient scope or strength, others may independently develop
similar technologies or products, duplicate any of our products or design around
our patents, and the patents may not provide us competitive advantages. Further,
patents held by third parties may not prevent the commercialization of products
incorporating our

46
<PAGE>
technologies or third parties may challenge or seek to narrow, invalidate or
circumvent any of our pending or future patents. We also believe that foreign
patents, if obtained, and the protection afforded by such foreign patents and
foreign intellectual property laws, may be more limited than that provided under
United States patents and intellectual property laws. Litigation, which could
result in substantial costs and diversion of effort by us, may also be necessary
to enforce any patents issued or licensed to us or to determine the scope and
validity of third-party proprietary rights. Any such litigation, regardless of
outcome, could be expensive and time-consuming, and adverse determinations in
any such litigation could seriously harm our business.

We also rely on unpatented trade secrets and know-how and proprietary
technological innovation and expertise which are protected in part by
confidentiality and invention assignment agreements with our employees, advisors
and consultants and non-disclosure agreements with certain of our suppliers and
distributors. These agreements may be breached, we may not have adequate
remedies for any breach or our unpatented proprietary intellectual property may
otherwise become known or independently discovered by competitors. Further, the
laws of certain foreign countries may not protect our products or intellectual
property rights to the same extent as do the laws of the United States.

From time to time, third parties, including our competitors, may assert
patent, copyright and other intellectual property rights to technologies that
are important to us. We expect that we will increasingly be subject to license
offers and infringement claims as the number of products and competitors in our
market grows and the functionality of products overlaps. In this regard, in
early 1999, we received a written notice from Hybrid Networks in which Hybrid
claimed to have patent rights in certain technology. Hybrid requested that we
review our products in light of six of Hybrid's issued patents.

We, with the advice of counsel, believe the patents are invalid or are not
infringed by our products. However, others' patents, including Hybrid's, may be
determined to be valid, or some or all of our products may ultimately be
determined to infringe the Hybrid patents or those of other companies. Hybrid or
other companies may pursue litigation with respect to these or other claims. The
results of any litigation are inherently uncertain. In the event of an adverse
result in any litigation with respect to intellectual property rights relevant
to our products that could arise in the future, we could be required to obtain
licenses to the infringing technology, pay substantial damages under applicable
law, to cease the manufacture, use and sale of infringing products or to expend
significant resources to develop non-infringing technology. Licenses may not be
available from third parties, including Hybrid, either on commercially
reasonable terms or at all. In addition, litigation frequently involves
substantial expenditures and can require significant management attention, even
if we ultimately prevail. Accordingly, any infringement claim or litigation
against us could significantly harm our business, operating results and
financial condition.

47
<PAGE>
EMPLOYEES

As of December 31, 1999, we had 98 full-time employees, of whom 15 were
employed in the United States and 83 were employed in Israel. Of these full-time
employees, 53 were principally dedicated to research and development, 11 were
dedicated to sales, marketing and customer support and 24 were involved in
manufacturing and operations. None of our U.S. employees is represented by a
union.

Our Israeli subsidiary is subject to Israeli labor laws and regulations with
respect to our Israeli employees. These laws principally concern matters such as
paid annual vacation, paid sick days length of work day and work week, minimum
wages, pay for overtime, insurance for work related accidents, severance pay and
other conditions of employment.

Our Israeli subsidiary and our Israeli employees are subject to provisions
of the collective bargaining agreements between the Histadrut, the General
Federation of Labor in Israel, and the Coordination Bureau of Economic
Organizations, including the Industrialists Associations, by order of the
Israeli Ministry of Labor and Welfare. These provisions principally concern cost
of living expenses, recreation pay and other conditions of employment. Our
Israeli subsidiary provides our Israeli employees with benefits and working
conditions above the required minimums. Our employees are not represented by a
labor union. We have not experienced any work stoppages.

FACILITIES

We are headquartered in Cupertino, California, where we lease approximately
9,000 square feet of commercial space under a month-to-month sublease. These
facilities are used for executive office space, including sales and marketing
and finance and administration. We also lease approximately 27,000 square feet
of commercial space in Jerusalem, Israel under a term lease that expires on
December 31, 2003, subject to one five-year extension at our option. These
facilities are used for research and development activities and for product
assembly and testing.

LEGAL PROCEEDINGS

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

audit committee reviews our internal accounting procedures and considers and
reports to the board of directors with respect to other auditing and accounting
matters, including the selection of our independent auditors, the scope of
annual audits, fees to be paid to our independent auditors and the performance
of our independent auditors. The audit committee currently consists of
Messrs. Broad, Brownstein and Kaplan. The compensation committee reviews and
recommends to the board of directors the salaries, benefits and stock option
grants for all employees, consultants, directors and other individuals
compensated by us. The compensation committee also administers our stock option

has one or more executive officers serving as a member of our board of directors
or compensation committee.

compensation for serving on the board. Directors are reimbursed for their

STOCK OPTION PLANS

AMENDED AND RESTATED 2000 EMPLOYEE AND CONSULTANT EQUITY INCENTIVE
PLAN. The 2000 Employee and Consultant Equity Incentive Plan, or 2000 Plan, was
adopted by our board of directors and approved by our stockholders on
November 22, 1999 for the benefit of our officers, directors, employees,
advisors and consultants. The 2000 Plan provides for the issuance of stock-based
incentive awards, including stock options, stock appreciation rights, limited
stock appreciation rights, restricted stock, deferred stock, and performance
shares. An award may consist of one arrangement or benefit or two or more of
them in tandem or in the alternative. Under the 2000 Plan, awards covering no
more than 80% of the shares reserved for issuance under the plan may be granted
to any participant in any one year. An aggregate of 4,050,000 shares of common
stock was initially reserved for issuance under the 2000 Plan. On February 2,
2000 our board of directors approved an amendment to the 2000 Plan to increase
the total number of shares reserved for issuance under the plan from
4,050,000 shares to 7,500,000 shares, plus an annual increase to be added
automatically on the first day of each fiscal year, commencing in 2001, equal to
the lesser of (1) 1,350,000 shares or (2) 5% of the number of outstanding shares
on the last day of the immediately preceding fiscal year. This amendment was
approved by our stockholders on February 2, 2000.

55
<PAGE>
Each of our non-employee directors elected to the board of directors for the
first time after February 2, 2000 will receive, upon such election, an initial
grant of options to purchase 75,000 shares of common stock at fair market value
on the date of grant. These options will have a 10-year term and will vest over
a four-year period. In addition, each of our non-employee directors will receive
an annual grant of options to purchase 22,500 shares for each year during such
director's term. These options will have a 10-year term and will vest
immediately upon the date of grant. The foregoing award of options will be
granted automatically under the 2000 Plan.

The 2000 Plan will initially be administered by our board of directors,
although it may be administered by either our board of directors or any
committee of our board of directors. The board or committee is sometimes
referred to in this prospectus as the plan administrator. The plan administrator
may interpret the 2000 Plan and may prescribe, amend and rescind rules and make
all other determinations necessary or desirable for the administration of the
2000 Plan. The 2000 Plan permits the plan administrator to select the officers,
directors, employees, advisors and consultants, including directors who are also
employees, who will receive awards and generally to determine the terms and
conditions of those awards.

We may issue two types of stock options under the 2000 Plan: incentive stock
options which are intended to qualify under the Internal Revenue Code, and
non-qualified stock options. The option price of each incentive stock option
granted under the 2000 Plan must be at least equal to the fair market value of a
share of common stock on the date the incentive stock option is granted.

Stock appreciation rights and limited stock appreciation rights may be
granted under the 2000 Plan either alone or in conjunction with all or part of
any stock option granted under the 2000 Plan. A stock appreciation right granted
under the 2000 Plan entitles its holder to receive, at the time of exercise, an
amount per share equal to the excess of the fair market value at the date of
exercise of a share of common stock over a specified price fixed by the plan
administrator. A limited stock appreciation right granted under the 2000 Plan
entitles its holder to receive, at the time of exercise, an amount per share
equal to the excess of the change in control price of a share of common stock
over a specified price fixed by the plan administrator. A limited stock
appreciation right may only be exercised within the 30-day period following a
change in control.

Restricted stock, deferred stock and performance shares may be granted under
the 2000 Plan. The plan administrator will determine the purchase price,
performance period and performance goals, if any, with respect to the grant of
restricted stock, deferred stock and performance shares. Participants with
restricted stock and performance shares generally have all of the rights of a
stockholder. With respect to deferred stock, during the deferral period, subject
to the terms and conditions imposed by the plan administrator, the deferred
stock units may be credited with dividend equivalent rights. If the performance
goals and other restrictions are not

56
<PAGE>
attained, the participant will forfeit his or her shares of restricted stock,
deferred stock and/or performance shares.

In the event we merge or consolidate with another entity in which we are not
the surviving corporation, dissolve or liquidate or sell substantially all of
our assets, outstanding awards under the 2000 Plan may be assumed or replaced by
the successor corporation, if any, or its parent. If the successor corporation
or its parent does not assume outstanding awards or substitute equivalent
awards, such awards will automatically become fully vested and exercisable and
be released from any restrictions on transfer and repurchase or forfeiture
right.

The terms of the 2000 Plan provide that the plan administrator may amend,
suspend or terminate the 2000 Plan at any time, provided, however, that some
amendments require approval of our stockholders. Further, no action may be taken
which adversely affects any rights under outstanding awards without the holder's
consent. The 2000 Plan will terminate in 2010.

1999 EMPLOYEE AND CONSULTANT EQUITY INCENTIVE PLAN. The 1999 Employee and
Consultant Equity Incentive Plan, or 1999 Plan, was adopted by our board of
directors on June 4, 1999 and approved by our stockholders on July 15, 1999 for
the benefit of our officers, directors, employees, advisors and consultants. The
1999 Plan provides for the issuance of stock-based incentive awards, including
stock options, restricted stock and stock bonuses. An aggregate of 2,400,000
shares of common stock has been reserved for issuance under the 1999 Plan. As of
December 31, 1999, options to purchase an aggregate of 1,281,000 shares of
common stock were outstanding under the 1999 Plan with a weighted-average
exercise price of $0.50. We do not intend to grant options pursuant to the 1999
Plan following the offering. The 1999 Plan will automatically terminate in 2009.

The 1999 Plan may be administered by our board of directors or committee of
the board. The board of directors or committee of the board may interpret the
1999 Plan and may prescribe, amend and rescind rules and make all other
determinations necessary or desirable for the administration of the 1999 Plan,
except that some amendments require stockholder approval. In addition, the board
of directors or committee of the board may not take any action which would harm
the rights previously granted under the 1999 Plan without the holders' consent.

If we merge or consolidate with another entity or if we dissolve, liquidate
or sell substantially all of our assets, outstanding awards under the 1999 Plan
may be assumed or replaced by the successor corporation or its parent. If the
successor corporation or its parent does not assume outstanding awards or
substitute equivalent awards, the awards will terminate.

1996 EQUITY INCENTIVE PLAN. The 1996 Equity Incentive Plan, or 1996 Plan,
was adopted by our board of directors on March 25, 1996 and approved by our
stockholders on April 5, 1996 for the benefit of our officers, directors,
employees, advisors and consultants. The 1996 Plan provides for the issuance of
stock-based

57
<PAGE>
incentive awards, including stock options, restricted stock and stock bonuses.
An aggregate of 330,000 shares of common stock was initially reserved for
issuance under the 1996 Plan. On May 13, 1998, our board of directors adopted,
and on June 23, 1998 our stockholders approved, an amendment to the 1996 Plan to
increase the total number of shares reserved for issuance under the plan from
330,000 to 480,000 shares. As of December 31, 1999, options to purchase an
aggregate of 229,151 shares of common stock with a weighted-average exercise
price of $0.33 were outstanding under the 1996 Plan. We do not intend to grant
options pursuant to the 1996 Plan following the offering. The 1996 Plan will
automatically terminate in 2006.

The 1996 Plan may be administered by our board of directors or a committee
of the board. The board of directors or committee of the board may interpret the
1996 Plan and may prescribe, amend and rescind rules and make all other
determinations necessary or desirable for the administration of the 1996 Plan,
except that some amendments require stockholder approval. In addition, the board
of directors or committee of the board may not take any action which would harm
the rights previously granted under the 1996 Plan without the holders' consent.

If we merge or consolidate with another entity or if we dissolve, liquidate
or sell substantially all of our assets, outstanding awards under the 1996 Plan
may be assumed or replaced by the successor corporation or its parent. If the
successor corporation or its parent does not assume outstanding awards or
substitute equivalent awards, the awards will terminate.

2000 EMPLOYEE STOCK PURCHASE PLAN

On February 2, 2000, the board of directors adopted and our stockholders
approved our 2000 Employee Stock Purchase Plan, or Purchase Plan, which allows
eligible employees to purchase our common stock at a discount from fair market
value. A total of 750,000 shares of our common stock, plus an annual increase to
be added automatically on the first day of our fiscal year, commencing in 2001,
equal to the lesser of (a) 300,000 shares or (b) 1% of the number of outstanding
shares on the last trading day of the immediately preceding fiscal year has been
reserved for issuance under the Purchase Plan.

The Purchase Plan will be administered by our board of directors, or a
specifically designated committee of the board of directors. The board or
committee is sometimes referred to in this prospectus as the plan administrator.
The plan administrator may interpret the Purchase Plan and, subject to its
provisions, may prescribe, amend and rescind rules and make all other
determinations necessary or desirable for the administration of the Purchase
Plan.

The Purchase Plan contains consecutive, overlapping 24-month offering
periods. Each offering period includes four purchase periods. The offering
periods generally commence on the first trading day on or after May 15 and
November 15 of each year and end on the last trading day on the date twenty-four
months later; provided,

58
<PAGE>
however, that the first offering period under the Purchase Plan will commence
upon the completion of the offering and end on the last trading day on or before
May 14, 2002.

Employees are eligible to participate if they are employed by us or any
participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, an employee may not be granted the right
to purchase stock under the Purchase Plan if the employee (a) immediately after
the grant would own stock possessing 5% or more of the total combined voting
power or value of all classes of our capital stock, or (b) holds rights to
purchase stock under any of our employee stock purchase plans that together
accrue at a rate which exceeds $25,000 worth of stock for each calendar year.
The Purchase Plan permits each employee to purchase common stock through payroll
deductions of up to 15% of the employee's compensation. The maximum number of
shares an employee may purchase during a single offering period is 15,000
shares.

Amounts deducted and accumulated by the employee are used to purchase shares
of common stock at the end of each purchase period. The price of the common
stock offered under the Purchase Plan is an amount equal to 85% of the lower of
the fair market value of the common stock at the beginning of each offering
period or at the end of each purchase period. In the event the fair market value
at the end of a purchase period is less than the fair market value at the
beginning of the corresponding offering period, the participants of the affected
offering period will be withdrawn from such offering period following exercise
of their options and automatically re-enrolled in a new offering period.
Employees may end their participation in the Purchase Plan at any time during an
offering period, in which event, any amounts withheld through payroll deductions
and not otherwise used to purchase shares will be returned to them.
Participation ends automatically upon termination of employment with us.

Rights granted under the Purchase Plan are not transferable by an employee
other than by will or the laws of descent and distribution. The Purchase Plan
provides that, in the event of a merger, consolidation, reorganization,
recapitalization, stock dividend or other change in corporate structure
affecting the number of issued shares of our common stock, the plan
administrator will conclusively determine the appropriate equitable adjustments.
The Purchase Plan will terminate in 2010. Our board of directors has the
authority to amend or terminate the Purchase Plan, except that no amendment or
termination may adversely affect any outstanding rights under the Purchase Plan.

LIMITATION OF LIABILITY AND INDEMNIFICATION

Upon completion of this offering, our certificate of incorporation will
limit the liability of our directors to the maximum extent permitted by Delaware
law. Delaware law provides that directors will not be personally liable for
monetary damages for breach of their fiduciary duties as directors, except
liability for:

- any breach of their duty of loyalty to the corporation or its
stockholders;

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

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

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

This provision will have no effect on any non-monetary remedies that may be
available to us or our stockholders, nor will it relieve us or other officers or
directors from compliance with federal or state securities laws.

Upon completion of this offering, our certificate of incorporation and
bylaws will also generally provide that we will indemnify, to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law, any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit, investigation, administrative hearing or any other
proceeding by reason of the fact that he or she is or was a director or officer
of ours, or is or was serving at our request as a director, officer, employee or
agent of another entity, against expenses incurred by him or her in connection
with that proceeding. An officer or director will not be entitled to
indemnification by us if:

- the officer or director did not act in good faith and in a manner
reasonably believed to be in, or not opposed to, our best interests; or

- with respect to any criminal action or proceeding, the officer or director
had reasonable cause to believe his or her conduct was unlawful.

In addition, we plan to enter into indemnification agreements with our
directors containing provisions which may require us, among other things, to
indemnify our directors against various liabilities that may arise by virtue of
their status or service as directors and to advance their expenses incurred as a
result of any proceeding against them as to which they could be indemnified.
Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers or persons controlling Vyyo pursuant to the
foregoing provisions or otherwise, Vyyo has been informed that in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

At the present time, there is no pending ligation or proceeding involving
any director, officer, employee or agent of Vyyo which indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding which may result in a claim for such indemnification.

into the number of shares set forth below. In December 1999, the warrants were

DESCRIPTION OF CAPITAL STOCK

The following description summarizes information regarding our capital
stock. This information is subject in all respects to the applicable provisions
of the Delaware General Corporation Law, our amended and restated certificate of
incorporation and bylaws.

Immediately following the closing of this offering, the authorized capital
stock of Vyyo will consist of 200,000,000 shares of common stock, $0.0001 par
value per share, and 5,000,000 shares of preferred stock, $0.001 par value per
share.

COMMON STOCK

VOTING RIGHTS. Each outstanding share of common stock is entitled to one
vote on all matters submitted to a vote of Vyyo's stockholders, including the
election of directors. There are no cumulative voting rights, and therefore the
holders of a plurality of the shares of common stock voting for the election of
directors may elect all of Vyyo's directors standing for election.

DIVIDENDS. Holders of common stock are entitled to receive dividends at the
same rate if and when dividends are declared by our board of directors out of
assets legally available for the payment of dividends, subject to preferential
rights of any outstanding shares of preferred stock. Through our subsidiary,
Vyyo Ltd., we participate in the "alternative benefits program" under the
Israeli law for the Encouragement of Capital Investments, 1959, under which we
realize certain tax exemptions. If Vyyo Ltd. distributes a cash dividend to Vyyo
Inc. from income which is tax exempt, it would have to pay corporate tax at the
rate of up to 25% on an amount equal to the amount distributed and the corporate
tax which would have been due in the absence of the tax exemption.

LIQUIDATION. In the event of a liquidation, dissolution or winding up of
the affairs of Vyyo, whether voluntary or involuntary, after payment of the
debts and other liabilities of Vyyo and making provisions for the holders of any
outstanding shares of preferred stock, the remaining assets of Vyyo will be
distributed ratably among the holders of shares of common stock.

RIGHTS AND PREFERENCES. The common stock has no preemptive, redemption,
conversion or subscription rights. The rights, powers, references and privileges
of holders of common stock and subject to, and may be adversely affected by, the
rights of the holders of shares of any series of preferred took that we any
designate and issue in the future.

PREFERRED STOCK

Upon the closing of this offering, all outstanding shares of preferred stock
will be automatically converted into shares of common stock. See note 8 to our
financial statements for a description of the preferred stock.

76
<PAGE>
The board of directors has the authority, without action by the
stockholders, to provide for the issuance of preferred stock in one or more
classes or series and to designate the rights, preferences and privileges of
each such class or series, which may be greater than the rights of the common
stock. We cannot predict the effect of the issuance of any shares of preferred
stock upon the rights of holders of the common stock until the board of
directors determines the specific rights of the holders of the preferred stock.
However, the effects could include one or more of the following:

- restricting dividends on the common stock;

- diluting the voting power of the common stock;

- impairing the liquidation rights of the common stock; or

- delaying or preventing a change in control of us without further action by
the stockholders.

We have no present plans to issue any shares of preferred stock.

REGISTRATION RIGHTS

Upon completion of the offering, the holders of an aggregate of
approximately 6,707,433 shares of common stock will be entitled to rights with
respect to the registration of these shares under the Securities Act of 1933, as
amended, or the Securities Act. Under the terms of the registration rights
agreements, if Vyyo proposes to register any of its securities under the
Securities Act, either for its own account or for the account of other security
holders exercising registration rights, these holders are entitled to notice of
this registration and are entitled to include shares of common stock in the
registration. The rights are subject to conditions and limitations, among them
the right of the underwriters of an offering subject to the registration to
limit the number of shares included in the registration. These registration
rights have been waived with respect to this offering. Holders of these rights
may also require Vyyo to file a registration statement under the Securities Act
at its expense with respect to their shares of common stock, and Vyyo is
required to use its best efforts to effect this registration, subject to
conditions and limitations. Furthermore, stockholders with registration rights
may require Vyyo to file additional registration statements on Form S-3, subject
to conditions and limitations.

DELAWARE ANTI-TAKEOVER LAW

We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takeover law. Generally, Section 203 of the Delaware General Corporation
Law prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years after
the date of the transaction in which the person became an interested
stockholder, unless:

- prior to the date of the business combination, the transaction is approved
by the board of directors of the corporation;

77
<PAGE>
- upon consummation of the transaction which resulted in the stockholder
becoming an interested stockholder, the interested stockholder owns at
least 85% of the outstanding voting stock of the corporation; or

- on or after the date of the business combination, such business
combination is approved by the board of directors of the corporation and
by the affirmative vote of at least 66 2/3% of the outstanding voting
stock which is not owned by the interested stockholder.

A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the stockholder. An "interested stockholder"
is a person who, together with affiliates and associates, owns (or within the
three-year period immediately prior to the relevant date, did own) 15% or more
of the corporation's outstanding voting stock. The existence of this provision
would be expected to have an anti-takeover effect with respect to transactions
not approved in advance by our board of directors, including discouraging
attempts that might result in a premium over the market price for the shares of
common stock held by stockholders.

TRANSFER AGENT AND REGISTRAR

EquiServe Trust Company will serve as Transfer Agent and Registrar for our
common stock. Its telephone number is (781) 575-2000.

Banc of America Securities LLC may release all or a portion of the shares
subject to this lockup agreement at any time without notice. See "Underwriting."

In general, under Rule 144, as currently in effect, a person who has
beneficially owned shares of our common stock for at least one year would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of:

- 1% of the number of shares of common stock then outstanding, which will
equal approximately 336,973 shares immediately after this offering; or

- the average weekly trading volume of the common stock on the Nasdaq
National Market during the four calendar weeks preceding the filing of a
notice on Form 144 with respect to the sale.

Sales under Rule 144 are also subject to manner of sales provisions and
notice requirements and to the availability of current public information about
us.

Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell the shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

Rule 701, as currently in effect, permits resales of shares in reliance upon
Rule 144 but without compliance with certain restrictions, including the holding

79
<PAGE>
period requirement, of Rule 144. Any of our employees, officers, directors or
consultants who purchased shares under a written compensatory plan or contract
may be entitled to rely on the resale provisions of Rule 701. Rule 701 permits
affiliates to sell their Rule 701 shares under Rule 144 without complying with
the holding period requirements of Rule 144. Rule 701 further provides that
non-affiliates may sell their shares in reliance on Rule 144 without having to
comply with the holding period, public information, volume limitation or notice
provisions of Rule 144. All holders of Rule 701 shares are required to wait
until 90 days after the date of this prospectus before selling their shares.
However, substantially all Rule 701 shares are subject to lock-up agreements and
will only become eligible for sale at the earlier of the expiration of the
180-day lock-up agreements or no sooner than 90 days after the offering upon
obtaining the prior written consent of Banc of America Securities LLC.

We intend to file a registration statement registering shares of common
stock subject to outstanding options or reserved for future issuance under our
stock plans. As of February 29, 2000, options to purchase a total of 4,161,195
shares were outstanding under our stock option plans of which 390,000 are issued
shares that are subject to a right of repurchase held by Vyyo. Common stock
issued upon exercise of outstanding vested options, other than common stock
issued to our affiliates, is available for immediate resale in the open market.

The underwriters initially will offer shares to the public at the price
specified on the cover page of this prospectus. The underwriters may allow to
some dealers a concession of not more than $0.52 per share. The underwriters
also may allow, and any other dealers may reallow, a concession of not more than
$0.10 per share to some other dealers. If all the shares are not sold at the
initial public offering price, the

81
<PAGE>

underwriters may change the offering price and the other selling terms. The
common stock is offered under a number of conditions, including:

- receipt and acceptance of our common stock by the underwriters, and

- the right to reject orders in whole or in part.

We have granted an option to the underwriters to buy up to 1,012,500
additional shares of common stock. These additional shares would cover sales of
shares by the underwriters which exceed the number of shares specified in the
table above. The underwriters have 30 days to exercise this option. If the
underwriters exercise this option, they will each purchase additional shares
approximately in proportion to the amounts specified in the table above.

The expenses of the offering that are payable by us are estimated to be
$1,600,000.

We, all our stockholders and all of our officers and directors have entered
into lock-up agreements with the underwriters. Under those agreements, we and
those holders of stock and options may not dispose of or hedge any common stock
or securities convertible into or exchangeable for shares of common stock. These
restrictions will be in effect for a period of 180 days after the date of this
prospectus. At any time and without notice, Banc of America Securities LLC may,
in its sole discretion, release all or some of the securities from these lock-up
agreements.

We will indemnify the underwriters against some liabilities, including some
liabilities under the Securities Act. If we are unable to provide this
indemnification, we will contribute to payments the underwriters may be required
to make in respect of those liabilities.

Our common stock has been approved for quotation on the Nasdaq National
Market under the symbol "VYYO."

In connection with this offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include:

- short sales,

- stabilizing transactions, and

- purchase to cover positions created by short sales.

Short sales involve the sale by the underwriters of a greater number of
shares than they are required to purchase in this offering. Stabilizing
transactions consist of bids or purchases made for the purpose of preventing or
retarding a decline in the market price of the common stock while this offering
is in progress.

The underwriters also may impose a penalty bid. This means that if the
representatives purchase shares in the open market in stabilizing transactions
or to cover short sales, the representatives can require the underwriters that
sold those shares as part of this offering to repay the underwriting discount
received by them.

82
<PAGE>
The underwriters may engage in activities that stabilize, maintain or
otherwise affect the price of the common stock, including:

- over-allotment,

- stabilization,

- syndicate covering transactions, and

- imposition of penalty bids.

As a result of these activities, the price of the common stock may be higher
than the price that otherwise might exist in the open market. If the
underwriters commence these activities, they may discontinue them at any time.
The underwriters may carry out these transactions on the Nasdaq National Market,
in the over-the-counter market or otherwise.

The underwriters do not expect sales to discretionary accounts to exceed 5%
of the total number of shares of common stock offered by this prospectus.

Prior to this offering, there has been no public market for our common
stock. The initial public offering price was negotiated between us and the
underwriters. Among the factors that will be considered in the negotiations are:

- our history and prospects, and the history and prospects of the industry
in which we compete,

- our past and present financial performance,

- an assessment of our management,

- the present state of our development,

- our prospects for future earnings,

- the prevailing market conditions of the applicable U.S. securities market
at the time of this offer,

- market valuations of publicly traded companies that we and the
underwriters believe to be comparable to US.

The underwriters have reserved up to 337,500 shares of the common stock to
be sold in this offering for sale to some of our employees, directors and their
associates, and to other individuals or companies who have commercial
arrangements or personal relationships with us. Through this directed share
program, we intend to ensure that those individuals and companies that have
supported us, or who are in a position to support us in the future, have the
opportunity to purchase our common stock at the same price that we are offering
our shares to the general public. We do not currently expect that more than
approximately 300 individuals (including our employees, directors and their
associates) and companies will participate in the directed share program.
Prospective participants will not receive any investment materials other than a
copy of this prospectus, and will be permitted to participate in this offering
at the

83
<PAGE>
initial public offering price presented on the cover page of this prospectus. No
commitment to purchase shares by any participant in the directed share program
will be accepted until after the registration statement of which this prospectus
is a part is effective and an initial public offering price has been
established. The number of shares available for sale to the general public will
be reduced by the number of shares sold through the directed share program.

A limited number of shares allocated to W.R. Hambrecht + Co., LLC will be
distributed in this offering through the use of the Internet. W.R. Hambrecht +
Co., LLC will post on its Web site (www.wrhambrecht.com) a brief description of
the offering. Visitors to this Web site will have access to the preliminary
prospectus by links on the Web site. W.R. Hambrecht + Co., LLC will accept
conditional offers to purchase shares from account holders that are determined
eligible to participate. In the event that the demand for shares exceeds the
amount of shares allocated to it, W.R. Hambrecht + Co., LLC will allocate shares
to individual and institutional account holders, considering the following
criteria: trading history of the account with respect to initial public
offerings, post-offering activity in previous offerings and tenure of the
account.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders

Vyyo Inc.

We have audited the accompanying consolidated balance sheets of Vyyo Inc. as
of December 31, 1998 and 1999, and the related consolidated statements of
operations, stockholders' equity (net capital deficiency) and cash flows for
each of the three years in the period ended December 31, 1999. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Vyyo Inc. at
December 31, 1998 and 1999, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1999, in conformity with generally accepted accounting principles in the United
States.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 1999

1. BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION AND BASIS OF PRESENTATION

Vyyo Inc. was incorporated as a Delaware corporation in 1996. In
January 2000, the Company changed its name from PhaseCom, Inc. to Vyyo Inc. and
its subsidiary (collectively, "Vyyo" or the "Company") is a global provider of
broadband wireless access systems used by telecommunications service providers
to deliver wireless high-speed data connections to businesses and residential
subscribers. The Company sells its products directly to service providers and to
system integrators. The majority of the Company's revenues are generated from
sales to customers in North America.

The Company's consolidated financial statements reflect the operations of
Vyyo Inc. and its wholly owned Israeli subsidiary, Vyyo Ltd. All significant
intercompany transactions and balances have been eliminated in consolidation.

REVENUE RECOGNITION

Net revenues include product revenues and in 1999 also include $480,000 of
technology development revenues. Product revenues are derived primarily from
sales of hubs and modems to telecommunications service providers and to system
integrators. Product revenues are generally recorded when products are shipped,
provided there are no customer acceptance requirements and the Company has no
additional performance obligations. The Company accrues for estimated sales
returns and exchanges and product warranty and liability costs upon recognition
of product revenues.

Technology development revenues are related to a best efforts arrangement
with a customer. Due to technology risk factors, the costs of the technology
development efforts are expensed when incurred and the revenues are recognized
when the applicable customer milestones are met, including deliverables, but not
in excess of the estimated amount that would be recognized using the
percentage-of completion method. We expect to complete this arrangement in
fiscal year 2000.

Deferred revenues represent amounts received from customers for products
subject to return or exchange and payments on technology development contracts
not yet recognized as revenue.

RISK FACTORS AND CONCENTRATIONS

The Company is subject to various risks similar to other companies in a
comparable stage of growth, including dependence on key individuals, competition
from substitute products and larger companies, the need to obtain additional
financing, and the continued successful development and marketing of its
products.

F-7
<PAGE>
VYYO INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

The Company used over $17 million in operating activities in 1997, 1998 and
1999. The Company will require additional financing to continue its operations
and execute its business plan. The Company believes adequate additional debt or
equity financing is available to fund planned operations through fiscal 2000.

Financial instruments that subject the Company to credit risk consist
primarily of uninsured cash and cash equivalents, most of which is held at
high-quality financial institutions in the United States and trade receivables.
The Company performs ongoing credit evaluations of its customers and generally
does not require collateral. The Company provides reserves for estimated credit
losses. Provisions for bad debts in 1997, 1998 and 1999 were $0, $11,000 and
$198,000, respectively. Write-offs of uncollectible accounts in 1999 was
$209,000 and none in 1997 and 1998.

Sales to one customer represented 12%, 31% and 20% of total revenues for the
years ended December 31, 1997, 1998 and 1999. Sales to two other customers
represented 11% and 27% of total revenues for the year ended December 31, 1997.
Sales to another customer represented 15% and 13% of total revenues for the
years ended 1998 and 1999. Sales to two other customers represented 14% and 12%,
respectively, of total revenues for the year ended December 31, 1999. Sales to
one other customer represented 23% of revenues for the year ended December 31,
1998.

In August 1999, ADC Telecommunications, Inc. ("ADC"), one of the Company's
major customers made an approximately 10% equity investment in the Company.
Revenues from ADC for the period from August 1999 through fiscal year end 1999
amounted to $654,000.

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 these estimates.

RESEARCH AND DEVELOPMENT

Research and development costs are expensed as incurred and consist
primarily of personnel, facilities, equipment and supplies for our research and
development activities.

PROPERTY AND EQUIPMENT

Property and equipment are recorded at cost. Depreciation and amortization
are provided using the straight-line method over the estimated useful lives of
the assets (generally from three to five years), or the life of the lease,
whichever is shorter.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

FOREIGN CURRENCY TRANSACTIONS

The U.S. dollar is the functional currency for the Company's foreign
subsidiary operations. Substantially all of the Company's foreign subsidiary's
sales are made in U.S. dollars. In addition, a substantial portion of the
foreign subsidiary's costs are incurred in U.S. dollars. Since the U.S. dollar
is the primary currency in the economic environment in which the foreign
subsidiary operates, and, accordingly, monetary accounts maintained in
currencies other than the U.S. dollar (principally cash and liabilities) are
remeasured using the foreign exchange rate at the balance sheet date.
Operational accounts and nonmonetary balance sheet accounts are measured and
recorded at the rate in effect at the date of the transaction. The effects of
foreign currency remeasurement are reported in current operations and have not
been material to date.

CASH EQUIVALENTS

The Company considers all highly liquid investments with maturity of three
months or less, at the date of purchase, to be cash equivalents.

NET LOSS PER SHARE

Basic and diluted net loss per share are presented in accordance with SFAS
No. 128, "Earnings per Share" ("SFAS 128"), for all periods presented. Pursuant
to the Securities and Exchange Commission Staff Accounting Bulletin No. 98,
common shares and convertible preferred shares issued or granted for nominal
consideration prior to the anticipated effective date of the Company's initial
public offering (the "Offering", see Note 12) must be included in the
calculation of basic and diluted net loss per share as if they had been
outstanding for all periods presented. To date, the Company has not had any
issuances or grants for nominal consideration.

Pro forma basic and diluted net loss per share have been computed using the
weighted-average number of common shares outstanding during the period. Pro
forma basic and diluted pro forma net loss per share, as presented in the
statements of operations, have been computed as described above and also give
effect to the conversion of all preferred shares that will convert automatically
upon completion of the Offering (using the as-if converted method) from original
date of issuance.

SHARE AND PER SHARE DATA

On January 3, 2000 and March 14, 2000, the Company effected a 1-for-5
reverse stock split and a 3-for-2 stock split of its common stock, respectively.
Common share, per common share data, and the preferred stock conversion rates
retroactively reflect the stock splits. As a result of the stock split, the
preferred stock is convertible to

F-9
<PAGE>
VYYO INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

common stock at the following ratios: Series A at 1 for 0.6, Series B at 1 for
0.3, and Series C at 1 for 0.3.

UNAUDITED PRO FORMA STOCKHOLDERS' EQUITY

All of the preferred shares will automatically be converted into common
shares upon completion of the Offering (see Note 8). The preferred stock is
convertible to common stock at the following split-adjusted ratios: Series A at
1 for 0.6, Series B at 1 for 0.3, and Series C at 1 for 0.3. Unaudited pro forma
stockholders' equity at December 31, 1999, as adjusted for the assumed
conversion of such shares, is disclosed on the balance sheet.

ACCOUNTING FOR STOCK-BASED COMPENSATION

The Company has elected to follow Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations in accounting for its employee stock options because the
alternative fair value accounting provided for under the Financial Accounting
Standards Board ("FASB") Statement No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123") requires use of option valuation models that were not
developed for use in valuing employee stock options. Under APB 25, when the
exercise price of the Company's employee stock or options equals the market
price of the underlying stock on the date of the grant, no compensation expense
is recognized.

During 1999, in connection with the grant of certain stock options and the
issuance of certain shares, the Company recorded deferred compensation expense
representing the difference between the option exercise price or the share
purchase price and the deemed fair value of the Company's common stock on the
date of grant. The deferred compensation costs are being amortized based on the
graded vesting method over the vesting period of the options.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standard Board (FASB) issued
Statement No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (SFAS No. 133) which establishes accounting and reporting standard
for derivatives instruments and hedging activities. The statement requires
recognition of all derivatives at fair value in the financial statements. FASB
Statement No. 137 "Accounting for Derivative Instruments and Hedging Activities
Deferral of the Effective Date of FASB Statement No. 133" an amendment of FASB
Statement No. 133, defers implementation of SFAS No. 133 until fiscal years
beginning after

F-10

VYYO INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

June 15, 2000. The Company believes that, upon implementation, the standard will
not have a significant effect on its financial condition or results of
operations.

2. INVENTORY

Inventory is stated at the lower of weighted-average actual cost or market.

CUSTOMER CLAIM

In 1997, a customer filed a claim against the Company in the amount of
approximately $300,000 alleging damages resulting from certain products being
delivered which did not meet product specifications. The Company no longer sells
or

F-13

VYYO INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

supports these products. The Company believes it has meritorious defenses
against these allegations and it plans to vigorously defend against them.

PATENT MATTER

In early 1999, the Company received a written notice from Hybrid Networks,
Inc. ("Hybrid"), a competitor, in which Hybrid claimed to have patent rights in
certain technology and requested that the Company review its products in light
of six of Hybrid's issued patents. The Company, with the advice of counsel,
believes the patents are invalid or are not infringed by the Company's products.
However, Hybrid may pursue litigation with respect to these or other claims. The
results of any litigation are inherently uncertain. Any successful infringement
claim or litigation against the Company could have a significant adverse impact
on operating results and financial condition.

RESEARCH GRANTS

Prior to 1997, the Company participated in the following research and
development incentive programs:

a. The Office of the Chief Scientist in the Israeli Ministry of Industry and
Trade (the "Chief Scientist)
The Company has obtained grants from the Chief Scientist totaling
approximately $2 million. These grants were received through 1996. The
terms of the grants from the Chief Scientist prohibit the transfer of
technology developed pursuant to the terms of these grants to any person,
without prior written consent of the Chief Scientist. These grants are
repayable to the Chief Scientist generally at the rate of 3% of the sales
of the products developed out of the projects funded, up to an amount
equal to 100% of the grant received.

b. Binational Industrial Research and Development Foundation (the "BIRD
Foundation")
The Company has participated in programs sponsored by the BIRD Foundation,
which funds joint US-Israeli teams in the development of technological
products. The Company received grants totaling approximately
$1.7 million from the BIRD Foundation for various projects. Grants
received from the BIRD Foundation are paid back at the rate of 2.5% to 5%
of revenues shown from the projects funded, up to a maximum amount equal
to 150% of the grants received.

As of December 31, 1999, the Company has repaid or provided for the
repayment of grants amounting to $651,000.

The holders of Series A, B, and C preferred stock are entitled to receive,
when and if declared by the board of directors, noncumulative dividends at the
annual rate of $0.0432, $0.08 and $0.0216 per share, respectively, and in that
order of preference, in preference to payment of dividends on common stock. No
dividends have been declared to date.

Each share of Series A, B, and C preferred stock is convertible, at the
holders' option or automatically as set forth below, into 0.6 share, 0.3 share
and 0.3 share, respectively, of common stock (as adjusted from time to time for
stock splits, stock dividends, and like events). Each share of Series A, B and C
preferred stock will automatically be converted into shares of common stock upon
either (i) the closing of an underwritten public offering of the Company's
common stock resulting in aggregate gross proceeds in excess of $12,500,000 with
a common stock per share purchase price of at least $3.33, or (ii) in a business
combination in which the common stock equivalent value of the Company's stock as
a result of such event is $3.33 or more per share (as adjusted from time to time
for stock splits, stock dividends, and like events). The holders of preferred
stock are entitled to one vote for each share of common stock into which such
preferred shares can be converted.

In the event of any liquidation, dissolution, or winding up of the Company
("Liquidation Event"), the holders of Series B preferred stock are entitled to
receive, in preference to holders of Series A preferred stock, Series C
preferred stock and

dividends. Before the payment of any portion of the Series A liquidation
preference price, the holders of Series C preferred stock are entitled to
receive $0.54 per share plus cumulative dividends of four percent per year in
excess of dividends actually paid or (ii) declared and unpaid dividends. Before
payment of any portion of the Series A liquidation preference price and after
payment of the Series B liquidation preference price and the Series C
liquidation preference price, in the event of a Liquidation Event, the holders
of Series A and Series B preferred stock and common stock are entitled to
receive an amount of $0.40 per share ("Series B to Common Stock Liquidation
Price"). After payment of the Series B to Common Stock Liquidation Price, the
holders of Series A preferred stock are entitled to receive, in preference to
holders of common stock, the amount of $4.60 per share plus any declared but
unpaid dividends.

WARRANTS

From 1997 through 1998, the Company issued warrants to purchase an aggregate
of 1,746,447 shares of common stock to investors in connection with equity and
convertible note financing transactions. As of December 31, 1999, 187,785
warrants remained outstanding with an average exercise price of $1.26 per share.
These warrants are exercisable through March 2002.

COMMON STOCK

As of December 31, 1999, the Company has reserved approximately 4,133,000
shares of common stock for issuance on the conversion of the Series A, B and C
convertible preferred stock and the warrants and 5,492,000 shares of common
stock for issuance of options granted under the stock-based compensation plan.

STOCK OPTION PLANS

The Company has the following stock option plans: (i) 1996 Equity Incentive
Plan, (ii) 1999 Employee and Consultant Equity Incentive Plan and (iii) 2000
Employee and Consultant Equity Incentive ("the Plans"). The plans as amended
provide for the grant to employees of incentive stock options ("ISOs"), the
grant to employees, directors, and consultants of nonstatutory stock options,
and the grant of stock options which comply with the applicable requirements of
Israeli law to the extent granted to persons who may be subject to income tax in
Israel. The Plans also provide for the awards of restricted stock and stock
bonuses.

ISOs granted under the Plans have an exercise price equal to the fair value
as determined by the board of directors of the common stock on the date of
grant.

F-16

VYYO INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

DECEMBER 31, 1999

Nonstatutory stock options may not be granted with an exercise price less than
85% of the fair value as determined by the board of directors of the common
stock on the date of grant. The period within which the option may be exercised
is determined at the time of grant, provided that no term is longer than ten
years. Options generally vest over a four-year period.

In October 1998, the Company adopted an option exchange program to allow
employees to exchange their options for new options with an exercise price of
$0.33. The program resulted in a total of approximately 295,800 options with
exercise price ranging from $1.00 to $2.10 being exchanged for the new options.
The terms of the repriced options remain the same.

A summary of stock option activity, and related information, under the Plans
for the years ended December 31, 1997, 1998 and 1999 is as follows (in
thousands, except per share data):

The weighted-average remaining contractual life of those options is 5.21
years.

Pro forma information regarding net loss is required by SFAS 123 and has
been determined as if the Company had accounted for its stock options under the
fair value method of SFAS 123. The fair value for the stock options was
estimated at the date of grant using a minimum value pricing model and a graded
vesting approach with the following weighted-average assumptions for 1997, 1998
and 1999: risk-free interest rate of 6.5%, 6.5% and 6.0%; dividend yields of
zero; and a weighted-average expected life of the option of approximately 3.6,
2.79 and 2.46 years.

Option valuation models require the input of highly subjective assumptions.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma SFAS 123 disclosures, the estimated fair value of
the options is amortized to expense over the option vesting periods.

10. INCOME TAXES

U.S. INCOME TAXES

As of December 31, 1999, the Company has U.S. federal and state net
operating loss carryforwards of approximately $19 million. The net operating
loss carryforwards will expire beginning in 2004 through 2019, if not utilized.
The utilization of net operating loss carryforwards may be subject to
substantial annual limitations if there has been a significant "change in
ownership." Such a "change in ownership," as described in Section 382 of the
Internal Revenue Code, may substantially limit the Company's utilization of the
net operating loss carryforwards.

ISRAELI INCOME TAXES

The Company's Israeli subsidiary has been granted "Approved Enterprise"
status for several investment programs, of which two are currently in effect.
Benefits pursuant to such investment plans include grants on a portion of the
costs of fixed assets, reduced tax rates, and, in certain cases, a full tax
exemption for certain periods. The entitlement to these benefits is conditional
upon the Company's fulfilling the conditions stipulated by the Investment Law,
regulations published thereunder, and the instruments of approval for the
specific investments in Approved Enterprises. In the event of a failure to
comply with these conditions, the benefits may be canceled and the Company may
be required to refund the amount of the benefits, in whole or in part, with the
addition of inflation adjustment differences and interest. The 1988 Investment
Plan will expire in 2001 and no benefits are expected to be realized under this
Plan. The 1996 Investment Plan entitles the Israeli subsidiary to a full tax
exemption ending 6 years after the year in which it utilizes its remaining
operating loss carryforwards and a reduced corporate tax rate of 10% to 15% for
the remaining period of the Plan's benefits, which will expire in 2009.

As of December 31, 1999, the Company has Israeli net operating loss
carryforwards of approximately $19 million. The Israeli loss carryforwards have
no expiration date and are expected to offset certain future Israeli subsidiary
earnings

during the tax exempt period. Management intends to re-evaluate its tax holiday
status and related tax asset at each balance sheet date.

Pretax losses from foreign (Israeli) operations was approximately
$5 million and $6 million for the years ended December 31, 1998 and 1999,
respectively.

DEFERRED INCOME TAXES

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets are as follows:

The valuation allowance increased by $13.5 million for the year ended
December 31, 1999.

FASB Statement No. 109 provides for the recognition of deferred tax assets
if realization of such assets is more likely than not. Based upon the weight of
available evidence, which includes our historical operating performance and the
reported cumulative net losses in all prior years, we have provided a full
valuation allowance against our net deferred tax assets as the future
realization of the tax benefit is not sufficiently assured.
