                                      XACCT

     We are a provider of business infrastructure software for
telecommunications carriers, Internet service providers, enterprise network
operators, wireless service providers and cable network operators, which we
refer to collectively as network service providers. Our software gives network
service providers a software infrastructure, or platform, that enables them to
leverage the rapid growth of Internet services and data traffic to increase
revenue opportunities. Our platform collects in real time and aggregates network
usage and traffic data from network elements such as routers, switches,
firewalls, servers and gateways and synthesizes that data into the information
and formats required by the operations and business support systems of network
service providers. As a result, our software enables or enhances billing,
customer care, price modeling, customer retention, fraud management, service
level verification and other systems. Network service providers use our
software's comprehensive real-time data collection, data aggregation and
automated service provisioning capabilities to deploy new business models and
higher-margin, enhanced services.

     As of June 30, 2000, we had licensed our business software to over 50
network service providers. Our customers include BCE Nexxia Inc., Broadwing
Communications, Cable & Wireless, PLC, CPG, Digital Island, Global One
Communications, L.L.C., Genuity Inc., Harvard University, Mannesman Ipulsys
B.V., TV Cabo Acoreana, S.A., UUNET Technologies, Inc., Verio Inc. and WorldCom
Inc. In addition, we have developed strategic alliances or collaborative
relationships with a group of over 85 system integrators, value-added resellers,
network infrastructure vendors and software applications vendors worldwide.

     As the volume of global Internet traffic has grown and demand for enhanced
Internet-based services has increased, network service providers have found that
their inability to capture, aggregate and transform raw network usage, traffic
and transaction data into meaningful business information has constrained their
revenue generation potential. We believe that a significant limitation on the
ability of network service providers to generate revenues from the Internet is
their lack of a flexible and scalable business infrastructure to implement
higher-margin, enhanced service offerings. The Yankee Group estimates that the
market for Internet business infrastructure will grow from $207 million in 1999
to $7.7 billion in 2004. In addition, The Insight Research Corporation estimates
that the market for operations support systems will grow from $33.9 billion in
2000 to $58.4 billion in 2005.

     Our infrastructure software enables network service providers to support
business models that feature differentiated services that are priced to reflect
the value of the services to the user and their respective cost to the network
service provider. Our software is designed to gather network usage, traffic and
transaction data from network elements in real time and to synthesize, enhance
and tailor that information to produce the specified information and formats
required by network service providers to implement these business models.
Network service providers can use this information to offer and charge their
customers appropriately for network services based on usage time, quality of
service, transactions, events, content or volume. These network services include
Internet telephony, web hosting, application renting, video conferencing,
movies/video on demand, audio over Internet protocol, unified messaging, network
games, virtual private networking, voice-mail, fax over Internet protocol,
e-mail and file transfers. This detailed information can also be used to support
customer relationship management, customer retention and fraud management
applications. In addition, our platform provides for automated service
provisioning, which allows for automated activation, authentication,
authorization and management of user accounts, and user self-provisioning. User
self-provisioning allows a network service provider's users to activate, modify
or deactivate services without the intervention of the network service provider.
By

                                       5
<PAGE>

automating the provisioning process, network service providers reduce their
costs, accelerate their time to revenue and increase user satisfaction.

     Our infrastructure software has been engineered to meet the demanding and
evolving performance and scalability requirements of network service providers.
Our software is designed to support network service providers that operate large
and complex networks with multiple services, also known as carrier-class
providers, as well as large businesses that operate networks within their
extended enterprises. Our software is designed with a distributed architecture,
meaning that discrete components of the larger software infrastructure are
deployed on or near network elements throughout the network to capture, filter,
aggregate and correlate usage, traffic and transaction data from multiple
elements and all layers of the network. This distributed architecture enables
data filtering and aggregation at the network element level and, by reducing the
volume of data sent over the network, reduces system capacity bottlenecks and
excessive bandwidth use. Our infrastructure solution can therefore scale with
the growth of our customers' networks and network traffic while maintaining data
integrity and high system availability. We have also designed our infrastructure
software as a platform that supports the varying operations and business support
systems employed by different network service providers. We believe our solution
is fully adaptable to all major network infrastructure technologies, including
hardware, software and operations and business support systems. We have also
designed our products to work with industry standard protocols to allow for the
rapid and seamless assimilation of new, emerging network standards, devices and
applications. Our solution also offers a wide range of web-based monitoring,
management and reporting capabilities.

     Our objective is to be the leading provider of business infrastructure
software to network service providers. Key elements of our strategy for
achieving this objective include:

     o    Enhancing our product line and extending our technology leadership;

     o    Expanding our collaborative relationships with technology providers to
          enhance our product offerings;

     o    Expanding and leveraging our relationships with systems integrators
          and value-added resellers;

     o    Leveraging our installed customer base to create new or additional
          sales opportunities; and

     o    Delivering our solution in strategically targeted international
          markets.

     Our principal executive offices are located at 2900 Lakeside Drive, Santa
Clara, California 95054 and our telephone number is (408) 654-9900. Our World
Wide Web address is www.xacct.com. The information on our web site is not part

                                  RISK FACTORS

     YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND ALL OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE PURCHASING OUR ORDINARY SHARES.
ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT WE
CURRENTLY SEE AS IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS. IF ANY OF
THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS COULD BE HARMED, THE TRADING
PRICE OF OUR ORDINARY SHARES COULD DECLINE AND YOU MAY LOSE ALL OR PART OF YOUR
INVESTMENT.


                          RISKS RELATED TO THE COMPANY

OUR LIMITED OPERATING HISTORY MAKES IT DIFFICULT TO EVALUATE OUR PROSPECTS AND
THE MERITS OF INVESTING IN OUR ORDINARY SHARES, AND OUR FUTURE FINANCIAL
PERFORMANCE MAY DISAPPOINT SECURITIES ANALYSTS OR INVESTORS AND RESULT IN A
DECLINE IN OUR SHARE PRICE.

     We were incorporated in June 1997. Through December 1998, we were engaged
primarily in the research and development of our initial product. We entered
into our first commercial license in January 1999 and have only recently
expanded our sales and service organizations. As a result of our limited
operating history, we have a limited amount of financial data that you can use
to evaluate our business. Moreover, the revenue and profitability potential of
our market is unproven. You must consider our prospects in light of the risks,
expenses and challenges we might encounter because we are at an early stage of
development in a new and rapidly evolving market. We may not successfully
address these risks, and our business strategy may not prove successful.

WE HAVE A LARGE ACCUMULATED DEFICIT, WE EXPECT FUTURE LOSSES AND WE MAY NOT
ACHIEVE OR MAINTAIN PROFITABILITY.

     We have incurred substantial losses since our inception as we funded the
development of our product and technologies and expanded our sales and marketing
organizations. Our net losses were $4.4 million for 1998, $9.1 million for 1999
and $16.7 million in the six months ended June 30, 2000. As of June 30, 2000, we
had an accumulated deficit of $30.9 million.

     In order to become profitable, we must increase our revenues. We may not be
able to increase or even maintain our revenues, and we cannot predict when we
will operate profitably, if at all. Even if sales of our XACCTUSAGE products
continue to grow, we expect to incur net losses for the foreseeable future due
to anticipated spending increases primarily on sales, marketing and research and
development efforts. Moreover, expected increases in competition will make it
difficult to increase our revenues. Even if we are able to increase revenues, we
may experience price competition, which could lower our gross margins and our
profitability. In addition, we anticipate that we may increase the percentage of
our revenues derived from indirect channels and services, which may carry lower
margin percentages than our direct sales. Increases in the percentage of our
revenues derived from indirect channels and services may consequently lower our
gross margin percentages. Even if we do achieve profitability, we may not
sustain or increase profitability on a quarterly or annual basis.

OUR OPERATING RESULTS FLUCTUATE SIGNIFICANTLY, AND AN UNANTICIPATED DECLINE IN
REVENUES MAY DISAPPOINT SECURITIES ANALYSTS OR INVESTORS AND RESULT IN A DECLINE
IN OUR SHARE PRICE.

     Our growth rates may not be sustainable and you should not use our past
performance to predict future operating margins or results. We believe that
period-to-period comparisons of our historical results of operations are not
meaningful and are not a good predictor of our future performance. Our quarterly
operating results have fluctuated significantly in the past and we expect them
to fluctuate significantly in the future. Factors that could cause quarterly
fluctuations in our operating results include:

     o    variations in demand for the XACCTUSAGE software products and related
          services;

     o    our ability to develop, introduce and attain market acceptance of
          enhancements to XACCTUSAGE and new related products and services on a
          timely basis;

     o    new product and service introductions and pricing changes by our
          competitors;

     o    the mix of products and services sold by us and our competitors;

                                       9
<PAGE>


     o    the mix of sales channels through which our products and services are
          sold;

     o    the mix of our U.S. and international sales;

     o    the timing and nature of new product announcements, introductions or
          modifications by vendors of software applications, computer hardware
          and software platforms and networking products that work with our
          product line; and

     o    our ability to expand our operations, and the amount and timing of
          expenditures to expand our operations, including costs related to
          acquisitions of technologies and businesses.

     We forecast the volume and timing of orders for operational planning, but
these forecasts are based on many factors and subjective judgments. We cannot
assure you of their accuracy. If our forecasts for revenues or expenses were to
prove materially inaccurate, our financial results could be harmed. Because of
our limited operating history, we have limited insight into trends that may
emerge in our market and affect our business. Forecasting for operational
planning is further complicated by our recent rapid growth.

     As a result of the foregoing factors, it is likely that in some future
quarters or years our operating results will fall below the expectations of
securities analysts or investors, causing our share price to decline.

OUR REVENUES AND OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY AS A RESULT OF
VARIATIONS IN THE TIMING AND VOLUME OF CUSTOMER ORDERS FOR XACCTUSAGE SOFTWARE
PRODUCTS AND RELATED SERVICES, WHICH MAY RESULT IN A DECLINE IN OUR ORDINARY
SHARE PRICE.

     Our revenues and operating results in any given quarter or year depend upon
the volume and timing of customer orders and payments and the date of product
delivery. Historically, a substantial portion of our revenues in any given
quarter has been recorded in the third month of that quarter. We expect this
trend to continue and intensify. Since our operating expenses are based on
anticipated revenue levels and because a high percentage of these expenses are
relatively fixed, a delay in a sale or revenue recognition for a sale could
cause significant variations in our operating results from quarter to quarter
and cause unexpected results. Significant sales may also occur earlier than
expected, which could cause operating results for later quarters to compare
unfavorably with operating results for earlier quarters.

     We primarily depend upon new contracts and purchase orders to generate
revenues for each quarter. However, new contracts may not result in revenues in
the quarter in which the contracts were signed, and we may not be able to
predict accurately when revenues from those contracts will be recognized.

     As a result of the foregoing factors, it is likely that in some future
quarters our revenues will fall below our expectations and our financial
performance will be harmed.

BECAUSE THE SALES AND IMPLEMENTATION CYCLE FOR OUR PRODUCTS IS LONG AND OFTEN
UNPREDICTABLE, OUR REVENUES AND OPERATING RESULTS MAY VARY SIGNIFICANTLY FROM
QUARTER TO QUARTER, WHICH MAY CAUSE OUR ORDINARY SHARE PRICE TO FLUCTUATE.

     Customers often use our product line to deploy mission-critical solutions
for their businesses. Our customers generally consider a wide range of issues
before committing to license our products, including assessing the benefits of
our products and our competitors' products, as well as assessing the ability of
our products to operate with existing and future computer systems and
accommodate increased transaction volume and product reliability. Many of our
customers will be addressing these issues for the first time. As a result, we or
other parties, including system integrators, must educate potential customers on
the use and benefits of our products and services. In addition, the purchase of
our products generally involves a significant commitment of capital and other
resources by a customer. This commitment often requires significant technical
review, assessment of competitive products, approval at a number of management
levels within the customer's organization and dedication of personnel support to
facilitate the deployment of our products.

     Because of these considerations and challenges, our sales cycle, from
initial evaluation to installation and acceptance, generally has ranged from
three to nine months and is difficult to predict for any particular transaction
or customer. Our customers often begin by licensing our products on a trial
basis before committing to additional licenses for full deployment. Furthermore,
our customers tend to deploy the XACCTUSAGE infrastructure slowly, depending
upon the customer's capabilities, the size of deployment, the complexity of the
customer's network

                                       10
<PAGE>

environment and the quantity of the hardware and the degree of hardware
configuration necessary to deploy our products. The long and often unpredictable
sales and implementation cycles for our products may cause revenues and
operating results to vary significantly from quarter to quarter.

BECAUSE A SMALL NUMBER OF CUSTOMERS ACCOUNT FOR AND ARE LIKELY TO CONTINUE TO
ACCOUNT FOR A SUBSTANTIAL PORTION OF OUR REVENUES, THE LOSS OF ONE OF THESE
CUSTOMERS OR THE CANCELLATION OR DEFERMENT OF A CUSTOMER'S ORDER WOULD CAUSE OUR
REVENUES TO DECLINE SUBSTANTIALLY AND MAY RESULT IN A DECLINE IN OUR SHARE
PRICE.


     In any given period, a relatively small number of customers generally
account for a significant portion of our total revenues. For example, in 1999,
sales to our ten largest customers accounted for 84% of our revenues, among
which, sales to TV Cabo Acoreana, S.A., UUNET Technologies, Inc., Genuity Inc.
and Verio Inc. accounted for 51% of our revenues. In the first two quarters of
2000, sales to Digital Island, CPG, Cable & Wireless, PLC and WorldCom, Inc.
accounted for 51% of our revenues. Moreover, some of the companies in our target
market of network service providers are consolidating, which could reduce the
number of available potential customers. The loss of a single prospective
customer might cause our revenues to decline substantially or fall short of our
expectations. In addition, we derive and expect to continue to derive a
significant portion of our revenues in each quarter from a small number of
relatively large customers. For example, in each of the two quarters in the
period ended June 30, 2000, we had two customers who together accounted for more
than 45% of our revenues for the quarter. If a large order is canceled or
deferred or if an anticipated order does not materialize, our operating results
for a particular quarter could be significantly harmed.


IF WE DO NOT CONTINUE TO ADD NEW CUSTOMERS, WE WILL NOT BE ABLE TO INCREASE OR
SUSTAIN OUR REVENUES.

     Our license arrangements do not generally provide for substantial ongoing
license payments. Therefore, our future revenue growth depends on our success in
attracting new customers or expanding our relationships with existing customers.
Our ability to attract new customers and expand our relationships with existing
customers will depend on a variety of factors, including the performance,
quality, breadth and depth of our current and future products and services. Our
failure to add new customers or expand our relationships with existing customers
would reduce our future revenues.

IF WE CANNOT CONVINCE NETWORK SERVICE PROVIDERS THAT OUR SOLUTION PROVIDES A
MEANS TO EXPAND THEIR REVENUE GENERATION POTENTIAL, WE WILL BE UNABLE TO
INCREASE OR SUSTAIN OUR REVENUES.

     Our solution offers a software infrastructure that is designed to enable
network service providers to implement new business models and offer
higher-margin, enhanced services to expand their revenue generation potential.
The market for business infrastructure software for network service providers
has only recently emerged and is rapidly evolving. A viable market for business
infrastructure software, and for XACCTUSAGE in particular, may not develop and
our product line may not achieve or sustain market acceptance. Our solution has
achieved only limited adoption and there is limited information upon which to
evaluate whether a large number of potential customers will purchase our
solution to replace or expand their existing revenue generation models. In
addition, we cannot assure you that a superior solution enabling network service
providers to better capitalize on the growth of Internet services and data
traffic will not emerge. If we cannot convince network service providers that
our solution is superior to their current revenue generation models that are
based on flat-fee pricing or if we cannot educate potential customers, and
specifically their senior management, on the use and benefits of our products,
we will be unable to increase or sustain revenues. Further, if network service
providers develop their own software infrastructure solutions or decrease their
spending on software infrastructure or if we fail to penetrate these markets,
our operating results will suffer.

IF WE CANNOT MEET THE TECHNICAL AND CAPACITY REQUIREMENTS OF NETWORK SERVICE
PROVIDERS, WE WILL BE UNABLE TO INCREASE OR SUSTAIN OUR REVENUES.

     Our product line may not be capable of satisfying the demanding technical
and capacity requirements of network service providers, many of which require
performance levels far in excess of that for which our products have been used
to date. We have only licensed our product line to a small number of customers,
and only a portion of these customers has commenced commercial deployment.
Moreover, network service providers will likely have changing requirements that
will require us to change our product designs or features, sales methods,
support capabilities or pricing policies. We may not successfully upgrade
XACCTUSAGE, and we may not successfully develop new products or services that
meet the expanding needs of network service providers. If we cannot continue

                                       11
<PAGE>

to meet the expanding requirements of network service providers, we will be
unable to increase or sustain our revenues.

OUR OPERATING RESULTS TO DATE HAVE DEPENDED UPON REVENUES FROM ONE PRODUCT LINE,
XACCTUSAGE, AND OUR BUSINESS COULD BE MATERIALLY HARMED BY FACTORS THAT
ADVERSELY AFFECT THE PRICING AND DEMAND FOR THAT PRODUCT LINE.

     Our future growth depends upon the commercial success of XACCTUSAGE. We
currently derive all of our revenues from the licensing, maintenance and support
of our XACCTUSAGE product line. We expect that we will continue to rely on new
and enhanced versions of XACCTUSAGE for a substantial portion of our revenues
for the foreseeable future. However, the limited sales and development of our
product line make our future prospects difficult to predict.

     Any decline in demand for XACCTUSAGE as a result of competition,
technological change or other factors would significantly reduce our revenues.

IF OUR PRODUCT LINE FAILS TO OPERATE WITH THE MANY HARDWARE, SOFTWARE AND
NETWORKING PLATFORMS USED BY OUR CUSTOMERS, OUR BUSINESS MAY FAIL.

     We currently target a customer base that uses a wide variety of constantly
changing software applications and programming tools, network infrastructure
products and hardware and software platforms. The success of our product line
depends upon our ability to address technical challenges, including:

     o    integrating our XACCTUSAGE product line with multiple software
          applications and programming tools, network infrastructure products,
          hardware and software platforms and existing systems, and modifying
          our product line as new applications, platforms, products and systems
          are introduced;

     o    expanding the functionality of our product line, particularly the
          number of operating systems and databases that our product line can
          source or target and the ability of our products to process a high
          number of transactions per second;

     o    anticipating and supporting new standards, especially Internet
          standards; and

     o    integrating additional software modules under development with our
          existing product line.

     If our product line fails to satisfy these demanding and rapidly changing
technological challenges, our customers will be dissatisfied and we may be
unable to generate significant future sales.

IF WE DO NOT DEVELOP AND MAINTAIN SUCCESSFUL RELATIONSHIPS WITH SYSTEMS
INTEGRATORS AND OTHER TECHNOLOGY PROVIDERS, OUR ABILITY TO MARKET AND SELL OUR
PRODUCTS WILL BE HARMED.

     We have entered into relationships with third-party systems integrators
that implement and increasingly resell XACCTUSAGE and related products and
services. We also have relationships with software applications, networking
products, hardware and software platform vendors to increase the flexibility of
our software platform and to pursue joint sales and marketing opportunities. We
have derived, and anticipate that we will continue to derive, a significant
portion of our revenues from customers that have relationships with these
technology providers. We could lose sales and marketing opportunities if we fail
to work effectively with these parties or fail to grow our base of applications,
networking products or platform vendors. We are currently investing and plan to
continue to invest significant resources to develop these relationships. Our
operating results could be adversely affected if these efforts do not generate
license and service revenues necessary to offset our significant investment in
building these relationships.

     Many of our technology providers also work with competing software
companies. Our success will depend upon the willingness of these providers to
select our solution as superior to competing alternatives and to devote
sufficient resources to market our product. We may not be able to enter into
additional, or maintain our existing, strategic relationships on commercially
reasonable terms, or at all. Our agreements with these parties typically are in
the form of nonexclusive agreements. Competing priorities may limit their
willingness to aggressively market and sell our products. Further,
notwithstanding our agreements with these parties, any party may discontinue
marketing our products or terminate our relationship without cause or on limited
notice. If these relationships fail, we will have to devote substantially more
resources to the distribution, sales, marketing, implementation and support of
our XACCTUSAGE product line than we would otherwise, and our singular efforts
may not be as effective as joint efforts.

                                       12
<PAGE>

     Technology providers may also pursue other relationships and may attempt to
develop or acquire products and services that compete with our products and
services. Our strategic relationships may also interfere with our ability to
enter into other desirable strategic relationships.

OUR BUSINESS WILL SUFFER IF WE FAIL TO INTRODUCE NEW VERSIONS AND RELEASES OF
OUR PRODUCTS IN A TIMELY MANNER.

     In the past we have failed to release some new products and upgrades on
time. We cannot assure you that we will meet project milestones for new versions
and releases. If we fail to develop and introduce new versions and releases of
our products in a timely manner and on a cost-effective basis, we could
experience:

     o    loss of or delay in revenues and loss of market share;

     o    customer dissatisfaction, loss of customers and cancellation of orders
          and license agreements;

     o    failure to achieve market acceptance;

     o    diversion of development resources;

     o    negative publicity and injury to our reputation;

     o    increased service and warranty costs;

     o    legal actions by customers against us; and

     o    increased insurance costs.

IF OUR SOFTWARE CONTAINS ERRORS OR DESIGN FLAWS OR HAS AN ADVERSE IMPACT UPON
OUR CUSTOMERS' NETWORKS, WE MAY LOSE CUSTOMERS, OUR COSTS WILL INCREASE AND
REVENUES MAY BE DELAYED OR LOST.

     Computer software such as ours generally contains undetected errors and may
contain design flaws that may adversely impact a user's networks. Because
customers use XACCTUSAGE to perform mission-critical applications, any problem
caused by our products may cause negative publicity and seriously harm our
reputation. Contractual limitations on liability contained in our license
agreements may not be enforceable, and we may be subject to claims based on
errors or design flaws in our software or mistakes in performing our services,
including claims relating to damages to our customers' internal systems. A
product liability claim, whether or not successful, could harm our business by
increasing our costs, damaging our reputation and distracting our management and
technical personnel.

THE UNAVAILABILITY OF AND DEFECTS IN THIRD PARTY SOFTWARE THAT WE INCORPORATE
INTO XACCTUSAGE COULD RESULT IN DELAYED OR LOST SALES AND INCREASED EXPENSES.

     Portions of XACCTUSAGE incorporate software developed and maintained by
third-party software vendors, such as operating systems, tools and database
vendors. For example, our programs use Java programming technology provided by
Sun Microsystems and database servers provided by Oracle. We expect that we may
have to incorporate software from third party vendors and developers to a larger
degree in our future products. Any significant interruption in the availability
of these third-party software products or defects in these products or future
products could harm our sales unless and until we can secure another source. We
may not be able to replace the functionality provided by third-party software
currently offered with our products if that software becomes obsolete, defective
or incompatible with future versions of our products or is not adequately
maintained or updated. The absence of, or any significant delay in, the
replacement of that functionality could result in delayed or lost sales and
increased costs and could harm our business.

     We also depend upon access to application programming interfaces used for
communication between external software products and packaged application
software. Application providers control our access to their application
programming interfaces. If these application providers deny or delay our access
to application programming interfaces, our business may be harmed. Some
application providers may become competitors or establish alliances with our
competitors, thereby, increasing the likelihood that we would not be granted
access to their application programming interfaces.

IF WE CANNOT SUCCESSFULLY EXPAND OUR SALES AND DISTRIBUTION CAPABILITIES, WE MAY
BE UNABLE TO INCREASE MARKET AWARENESS AND SALES OF OUR XACCTUSAGE PRODUCT LINE.

     We must expand our direct and indirect sales operations to increase market
acceptance of XACCTUSAGE and related product and services and to increase our
revenues. We may not be successful in these efforts. There is a shortage of
direct sales personnel with the skills and expertise necessary to sell our
products. Moreover, because our product line and services require sophisticated
sales efforts targeted at the senior management of our prospective customers,
new hires will require training before they can achieve productivity. We may not
be able to hire enough qualified individuals in the future, and our recently
hired sales personnel may not achieve expected productivity levels. We also plan
to expand our relationships with systems integrators and other third party
resellers to build an indirect sales channel. Accordingly, we will need to
manage potential conflicts between our direct and indirect sales forces. Failure
to expand our sales channels and manage their expansion would harm our revenues
and operating results and place us at a competitive disadvantage.

OUR GROWTH MAY SUFFER IF WE ARE UNABLE TO IMPLEMENT OUR PRODUCTS IN A TIMELY
MANNER.

     The use of our products by our customers requires consulting and
implementation services. While we have recently established relationships with
some third party providers, we continue to be the primary provider of consulting
and implementation services for our products. It is difficult and expensive to
recruit, train and retain qualified personnel to perform these services, and we
may from time to time have inadequate levels of staffing to perform these
services. As a result, our growth could be limited due to our lack of capacity
to provide consulting and implementation services or our inability to
subcontract these services to qualified third parties. In addition, we could
experience deterioration in service levels or decreased customer satisfaction,
any of which could harm our reputation and operating results.

UNANTICIPATED DIFFICULTIES IN IMPLEMENTING OUR PRODUCTS COULD SIGNIFICANTLY HARM
OUR REPUTATION WITH CUSTOMERS, INCREASE OUR COSTS AND DIMINISH OUR ABILITY TO
LICENSE ADDITIONAL PRODUCTS TO OUR CUSTOMERS.

     Our products are often purchased as part of large projects undertaken by
our customers. The costs of our products and services represent only a portion
of the related hardware, software, development, training and consulting costs of
these projects. These projects are complex, time consuming and expensive and
typically involve working with sophisticated software, computing and
communications systems. In many cases, our customers must interact with, modify
or replace significant elements of their existing computer systems. Some
customers may require us to develop costly customized features or capabilities,
which increase our costs and consume our limited professional service and
customer support resources. The significant involvement of third parties,
including system integrators, reduces the control we have over the
implementation of our products and the level, quality and timeliness of service
provided to customers that license our software. Failure by customers to
successfully deploy our products, or the failure by third-party consultants or
us to ensure customer satisfaction, could damage our reputation with existing
and future customers and reduce future revenues.

     If we experience difficulties with an implementation or do not meet project
milestones in a timely manner, we could be obligated to devote more customer
support, engineering and other resources to a particular project and to provide
these services at reduced or no cost.

IF WE ARE UNABLE TO INCREASE SERVICE REVENUES, OUR OPERATING RESULTS WILL BE
ADVERSELY AFFECTED.

     Our service revenues are derived from support and maintenance arrangements,
including product upgrades, consulting and training. Service revenues
constituted 25% of our revenues in 1999 and 20% in the six months ended June 30,
2000. The level of service revenues depends significantly on our ability to
continue to obtain renewals of customer support contracts by our installed
customer base, to provide effective customer care services and to release
product updates and modifications on a timely basis. Maintenance and support
contracts typically have 12-month terms and the growth of our service revenues
depend in part upon the renewal rates of those contracts. If third party
organizations such as systems integrators become proficient in installing or
servicing our product line, we may lose customer support contracts and our
service revenues could decline. In addition, if we are unable to increase the
scale of our service organization, including successfully recruiting and
training a sufficient number of qualified services personnel, we may not be able
to increase service revenues.

IF WE FAIL TO PROTECT OUR XACCT TRADEMARK, THE VALUE OF THE XACCT NAME WOULD
DECREASE AND WE MAY LOSE CUSTOMERS TO COMPETITORS.

     We have received an initial refusal of our application to register our
XACCT trademark in the United States. We are currently preparing a response to
the United States trademark office. If we receive a final rejection of our
application to register the XACCT trademark, we will likely experience greater
expense and difficulty in protecting the XACCT mark and its derivations. We may
not be able to enforce rights in our trademarks, and we may not be able to use
our trademarks in all jurisdictions. If the XACCT trademark is invalidated
through legal action, or if we were prevented from using our trademarks, we
would need to rebuild our brand identity and reputation with our customers,
system integrators, value-added resellers, network infrastructure vendors and
software application vendors. We would also have to devise new collateral
materials. If we needed to rebuild our brand identity or devise new collateral
materials, our operating expenses would substantially increase and our business
would be harmed. Conversely, we may be unable to stop others from using similar
marks in connection with other goods and services. If that happens, our existing
and potential customers and system integrators, value-added resellers, network
infrastructure vendors and software application vendors could confuse us and our
products and services with another company and its products and services. This
could weaken the value of the XACCT name and result in the loss of business to
our competitors, either of which would harm our operating results.

WE COULD BE CHARGED WITH TRADEMARK INFRINGEMENT AND INCUR SIGNIFICANT COSTS IN
CONTESTING THESE CHARGES AND FOR ANY RELATED LIABILITY.

     Other companies that use or have registrations for terms similar to XACCT
for various products and services or for their company or brand name could claim
that we are infringing their federal or state trademark rights by our use of the
mark XACCT or its derivations. An infringement claim of that nature, whether
meritorious or not, could be time consuming and result in the diversion of
management resources and costly litigation. In addition, it could result in our
loss of the right to use the mark XACCT and its derivations, including the right
to use them:

     o    in our corporate name;

     o    as part of the services we offer; and

     o    as part of our web site address, which is currently www.xacct.com.

     Litigation or settlement of an infringement claim could also require us to
pay damages or enter into royalty or licensing agreements on terms that are
unfavorable to us. If we are unable to use the mark XACCT and its derivations,
we will be required to adopt a new company and brand name and to market our
products and services under a new name. To do so, we will be required to incur
significant costs. Any of those events could significantly harm our business.

OUR GROWTH CONTINUES TO PLACE A SIGNIFICANT STRAIN ON OUR MANAGEMENT SYSTEMS AND
RESOURCES AND IF WE FAIL TO MANAGE OUR GROWTH, OUR ABILITY TO MARKET AND SELL
OUR XACCTUSAGE PRODUCT LINE AND DEVELOP NEW PRODUCTS MAY BE HARMED.

     We must plan and manage our growth in order to effectively market and sell
our product line and services and achieve revenue growth and profitability in a
rapidly evolving market. Our growth has and will continue to place a significant
strain on our management systems and resources, and we may not be able to
effectively manage our growth in the future. We continue to increase the scope
of our operations both in the U.S. and internationally, and have added a number
of employees. For example, the number of our employees grew from 93 at December
31, 1999 to 204 at June 30, 2000. In particular, our sales organization grew
from 22 at December 31, 1999 to 51 people at June 30, 2000. For us to
effectively manage our growth, we must continue to do the following:

     o    improve our operational, financial and management controls;

     o    improve our reporting systems and procedures;

     o    install new management and information control systems; and

     o    expand, train, motivate and manage our workforce.

     Additionally, we expect that we will have to continue to expand our
facilities and may face difficulties and significant expenses identifying and
moving into suitable office space. Expanding our operations will require

                                       15
<PAGE>

significant management attention and financial resources. We cannot be certain
that our investments in our growth will produce desired levels of revenue. Our
business will suffer dramatically if we fail to effectively manage our growth.

IF WE FAIL TO ATTRACT AND RETAIN QUALIFIED PERSONNEL, OR IF OUR MANAGEMENT FAILS
TO OPERATE EFFECTIVELY, WE WILL NOT BE ABLE TO IMPLEMENT OUR BUSINESS STRATEGY
OR OPERATE OUR BUSINESS EFFECTIVELY.

     Our success depends upon the continued services of our senior management
and other key personnel, many of whom would be difficult to replace. The loss of
any of these individuals would harm our ability to implement our business
strategy and to operate our business effectively. In particular, the services of
Eric Gries, our President and Chief Executive Officer, and Eran Wagner, our
Executive Vice President, Technology, would be difficult to replace. None of our
officers or key employees is bound by an employment agreement for any specific
term.


     We believe our success depends significantly upon our management's ability
to operate effectively, both individually and as a group. Richard Van Hoesen,
who was hired as Chief Financial Officer in January 2000, and certain other
members of the management team, have only recently joined us. We therefore
cannot assure you that our management will be able to perform effectively in
their respective roles and as a team.


     Our success also depends upon our ability to continue to attract, retain
and motivate skilled employees. Competition for employees in our industry is
intense, especially in the San Francisco Bay Area and Israel. We believe that
there are only a limited number of persons with the requisite skills to serve in
many key positions and it is becoming increasingly difficult to hire, retain and
motivate these persons. We have in the past experienced, and we expect to
continue to experience, difficulty in hiring and retaining skilled employees.
Competitors and others in the past have attempted, and may in the future
attempt, to recruit our employees. We believe that we will incur increasing
salaries, benefits and recruiting expenses because of the difficulty in hiring
and retaining employees.

ACQUISITIONS OF NEW COMPANIES OR TECHNOLOGIES MAY RESULT IN DISRUPTIONS TO OUR
BUSINESS AND STRAIN MANAGEMENT RESOURCES DUE TO DIFFICULTIES IN ASSIMILATING
PERSONNEL AND OPERATIONS.

     We may make future acquisitions or investments in other companies, products
or technologies. If we make any acquisitions, we will be required to assimilate
the operations, products and personnel of the acquired businesses and train,
retain and motivate key personnel from the acquired businesses. We may be unable
to maintain uniform standards, controls, procedures and policies if we fail in
these efforts. Similarly, acquisitions may cause disruptions in our operations
and divert management's attention from day-to-day operations, which could impair
our relationships with our current employees, customers and strategic partners.
The issuance of equity securities for any acquisition could be substantially
dilutive to our shareholders. In addition, our profitability may suffer because
of acquisition-related costs or amortization costs for acquired goodwill and
other intangible assets.

WE MAY FACE CLAIMS OF INVASION OF PRIVACY OR INAPPROPRIATE DISCLOSURE, AND WE
MAY NEED TO SPEND SIGNIFICANT RESOURCES TO PROTECT AGAINST OR CORRECT PROBLEMS
CAUSED BY SECURITY BREACHES.

     Because our software contains features which may allow us or our customers
to control, monitor or collect information from computers running our software
without notice to the computing users, we may face claims about invasion of
privacy or inappropriate disclosure, use or loss of this information. Any
imposition of liability could harm our operating results.

     Additionally, third parties may attempt to breach our security or that of
our customers. We may be liable to our customers for any breach in security and
any breach could harm our business or reputation. We may be required to expend
significant capital and other resources to further protect against security
breaches or to correct problems caused by any breach.

OUR OPERATIONS ARE SUBJECT TO BUSINESS INTERRUPTION DUE TO LACK OF ADEQUATE
PROTECTION AND BACK-UP SYSTEMS.

     Our operations are vulnerable to damage or interruption from computer
viruses, human error, natural disasters, intentional acts of vandalism and
similar events. We have not established a formal disaster recovery plan and our
back-up operations may be inadequate and our business interruption insurance may
not be enough to compensate us for losses that occur. Any sustained interruption
in our operations may harm our business and our ability to compete.

                          RISKS RELATED TO OUR INDUSTRY

IF WE DO NOT KEEP PACE WITH RAPID TECHNOLOGICAL CHANGE, CHANGING CUSTOMER
DEMANDS AND EVOLVING INDUSTRY STANDARDS, WE WILL NOT BE ABLE TO COMPETE.

     Our industry is characterized by rapid technological change, frequent
product introductions and enhancements, changes in customer demands and evolving
industry standards. The technological life cycle of our products is difficult to
estimate. Future versions of software applications and networking products,
hardware and software platforms embodying new technologies and the emergence of
new industry standards could render our product line obsolete. XACCTUSAGE may
not operate correctly on future networking environments, hardware and software
platforms, programming languages, database environments and software
applications that our customers may use. We may not be able to successfully
continue to enhance our current product line to address these challenges.
Moreover, we may not be able to develop and introduce new products that
anticipate emerging technology standards and keep pace with competitive and
technological developments to address the increasingly sophisticated needs of
our customers on a timely basis. Our failure to do so would render our products
obsolete and would harm our ability to compete.

WE MAY BE REQUIRED TO CHANGE OUR REVENUE RECOGNITION POLICIES BASED ON CHANGING
IMPLEMENTATION GUIDELINES AND INTERPRETATIONS WHICH MAY CAUSE OUR REVENUES AND
OPERATING RESULTS TO FLUCTUTATE UNEXPECTEDLY.


     In recent years, software revenue recognition rules have been under heavy
review and interpretation by various accounting authoritative and regulatory
bodies, including the Securities and Exchange Commission, the American Institute
for Certified Public Accountants and the Financial Accounting Standards Board.
These reviews and interpretations have resulted in significant changes in the
practices and standards for recognizing revenues in software companies.

     Our revenue recognition policies are in compliance with current accounting
standards. However, the rapid pace of change in these standards could result in
significantly different standards in the future and could have a material
adverse effect on our business, results of operations or financial position as
we change our practices to comply with such changing standards.

     At this time, we are unaware of any contemplated changes to current revenue
recognition standards that would cause such an effect on our business.


WE MAY SUFFER PRICE REDUCTIONS, LOSS OF CUSTOMERS, REDUCED GROSS MARGINS AND
LOSS OF MARKET SHARE DUE TO INCREASING COMPETITION.

     The market for our product line is new, evolving and subject to rapid
technological changes. To date, our primary competition has come from solutions
developed by the in-house technology departments of potential customers or
partners. We have experienced and expect to continue to experience increased
competition from current and potential competitors. Many of these companies have
greater name recognition, longer operating histories, larger customer bases and
significantly greater financial, technical, marketing, public relations, sales,
distribution and other resources. Some of our potential competitors are among
the largest and most well capitalized software, hardware and communications
companies in the world. Our competitors include:

     o    in-house information technology departments of potential customers or
          partners that have developed or may develop systems that substitute
          for some or all of the functionality of our XACCTUSAGE product;

     o    companies with products that address our market, such as Hewlett
          Packard Co., Lucent Technologies, Inc., EHPT Sweden AB, and Narus,
          Inc.; and

     o    companies that have developed software that addresses only certain
          components of Internet Protocol mediation.

     We are also aware of numerous other companies that are focusing significant
resources on developing and marketing products that will compete with
XACCTUSAGE. Additional competitors could come from a number of companies that
produce application integration or communications software.

     We expect that competition will increase in the near term and that our
primary long-term competitors may not have entered the market yet. If any of our
competitors were to become the industry standard or were to enter into or expand
relationships with significantly larger companies through mergers, acquisitions
or otherwise, our business

                                       17
<PAGE>

and operating results could be significantly harmed. Current and potential
competitors have established or may establish cooperative relationships among
themselves or with third parties to offer a single solution and increase the
ability of their products to address customer needs. Increased competition could
result in price reductions, fewer customer orders, reduced gross margins and
loss of market share, any of which could reduce our future revenues. We may not
compete successfully against current and potential competitors, especially those
with significantly greater resources.

THE GROWTH OF OUR BUSINESS DEPENDS ON THE INCREASING USE OF THE INTERNET AND
OTHER PUBLIC AND PRIVATE NETWORKS.

     We sell XACCTUSAGE to organizations providing Internet-based services. If
the use of the Internet and other public and private networks does not grow as
anticipated, our revenues could decline and our business would be significantly
harmed. We depend on the increased acceptance and use of the Internet as a
medium for electronic communications and commerce and its adoption for
transacting business processes. Rapid growth in the use of the Internet is a
recent occurrence. As a result, acceptance and use may not continue to develop
at historical rates and a sufficiently broad base of users may not adopt or
continue to use the Internet as a medium of communications and commerce. Demand
and market acceptance for recently introduced services and products for the
Internet are subject to a high level of uncertainty, and there exist few proven
services and products.

FUTURE REGULATION OF THE INTERNET MAY SLOW ITS GROWTH, RESULTING IN DECREASED
DEMAND FOR OUR PRODUCTS AND SERVICES AND INCREASED COSTS OF DOING BUSINESS.

     Due to the increasing popularity and use of the Internet, it is possible
that state and federal regulators will adopt laws and regulations that may
impose additional burdens on those companies conducting business over the
Internet. The growth and development of the market for Internet-based services
may prompt calls for more stringent consumer protection laws. The adoption of
any additional laws or regulations may decrease the expansion of the Internet. A
decline in the growth of the Internet could decrease demand for our products and
services or otherwise harm our business. Moreover, the applicability to the
Internet of existing laws in various jurisdictions governing issues such as
communications, property ownership, sales tax, libel and personal privacy is
uncertain and may take years to resolve. Any new legislation or regulation, the
application of laws and regulations from jurisdictions whose laws do not
currently apply to our business, or the application of existing laws and
regulations to the Internet and other on-line services could harm our growth.

IF WE FAIL TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS, WE MAY LOSE THESE
RIGHTS AND OUR BUSINESS WOULD BE SERIOUSLY HARMED.

     Our success and ability to compete depend upon our internally developed
technology and other proprietary rights, which we protect through a combination
of copyright, trademark and trade secret laws, as well as confidentiality
agreements and licensing arrangements. In addition, we have made two patent
applications in the United States regarding certain aspects of our technology.
However, existing laws afford only limited protection. Competitors and potential
competitors may develop products with the same functionality as our products.
Moreover, competitors and potential competitors may attempt to copy or reverse
engineer aspects of our product line or to obtain and use information that we
regard as proprietary. Policing the unauthorized use of our products is
difficult, and we cannot be certain that we will be able to prevent
misappropriation of our technology, particularly in foreign countries where the
laws may not protect proprietary rights as fully as do the laws of the United
States. Use by others of our proprietary rights could materially harm our
business, and expensive litigation may be necessary in the future to enforce our
intellectual property rights.

IF OUR SOURCE CODE IS RELEASED TO OUR CUSTOMERS, OUR ABILITY TO PROTECT OUR
PROPRIETARY RIGHTS COULD BE JEOPARDIZED AND OUR REVENUES COULD DECLINE.

     Some of our license agreements require us to place the source code for our
products in escrow. These agreements generally provide these customers with a
limited, non-exclusive license to use this code if:

     o    there is a bankruptcy, insolvency or winding-up proceeding involving
          us;

     o    we cease to do business without a successor; or

     o    we do not provide contractually agreed maintenance and support.

                                       18
<PAGE>


     Our revenues could decline and our business could be seriously harmed if
customers were granted access to our source code.

OUR PRODUCTS COULD INFRINGE THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS, WHICH
MIGHT RESULT IN COSTLY LITIGATION AND THE LOSS OF SIGNIFICANT RIGHTS.

     It is possible that third parties will claim that we have infringed their
intellectual property rights. Substantial litigation regarding intellectual
property rights exists in the software industry, and we expect that software
developers will be increasingly subject to infringement claims as the number of
competitors in our industry segment grows and the functionality of products in
different industry segments overlaps. Some of our competitors may have filed or
may intend to file patent applications covering aspects of their technology upon
which they may claim our technology infringes. Any claims, with or without
merit, could be time-consuming, result in costly litigation, prevent or delay
product shipment, divert the attention and resources of our management or
technical personnel or require us to develop non-infringing technology or to
enter into royalty or licensing agreements, any of which could harm our
business. Patent litigation in particular has complex technical issues and
inherent uncertainties. In the event an infringement claim against us was
successful and we could not obtain a license on acceptable terms, license a
substitute technology or redesign to avoid infringement, our business would be
harmed. Furthermore, former employers of our current and future employees may
assert that our employees have improperly disclosed to us or are using
confidential or proprietary information.

                          RISKS RELATED TO OUR OFFERING

THE SUBSTANTIAL NUMBER OF SHARES THAT WILL BE ELIGIBLE FOR SALE IN THE NEAR
FUTURE MAY CAUSE THE MARKET PRICE OF OUR ORDINARY SHARES TO DECLINE.

     Our current shareholders hold a substantial number of our ordinary shares
that they will be able to sell in the public market in the near future. Sales of
a substantial number of shares after this offering could significantly reduce
the market price of our ordinary shares. Even the perception that our current
shareholders might sell ordinary shares could depress the trading price of the
ordinary shares. These sales, and the possibility of these sales, could make it
more difficult for us to sell equity or equity-related securities in the future
at a time and price that we deem appropriate.


     Holders of approximately 16.7 million ordinary shares, which will represent
approximately 62% of our outstanding share capital after completion of this
offering, have the right to require us to register their ordinary shares with
the Securities and Exchange Commission. In addition, after this offering, we
intend to register all ordinary shares that we may issue under our share plans
and employee share purchase plan. Once we register these shares, they can be
freely sold in the public market upon issuance. If these holders cause a large
number of securities to be sold in the public market, the sales could reduce the
trading price of our ordinary shares. These sales also could impede our ability
to raise future capital.


WE EXPECT TO EXPERIENCE VOLATILITY IN OUR SHARE PRICE, WHICH COULD NEGATIVELY
AFFECT YOUR INVESTMENT.

     Our ordinary shares have never been sold in a public market and an active
trading market for our shares may not develop or be sustained. If you purchase
our ordinary shares in this offering, you will pay a price that was not
established in a competitive market. Rather, you will pay a price that we
negotiated with the representatives of the underwriters. The price of our
ordinary shares that will prevail in the market may be lower than the price you
pay.

     The market price of the ordinary shares may fluctuate significantly in
response to the following factors, most of which are beyond our control:

     o    variations in our quarterly operating results;

     o    changes in securities analysts' estimates of our financial
          performance;

     o    changes in market valuations of similar companies;

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

     o    loss of a major customer or failure to complete significant license
          transactions; and


                                       19
<PAGE>


     o    additions or departures of key personnel.

     Moreover, the market for technology and Internet-related companies has
experienced extreme volatility that often has been unrelated to the operating
performance of particular companies. These fluctuations may adversely affect the
trading price of our ordinary shares, regardless of our actual operating
performance. As a result, you may be unable to sell your ordinary shares at or
above the offering price.

WE ARE AT RISK OF SECURITIES CLASS ACTION LITIGATION DUE TO OUR EXPECTED SHARE
PRICE VOLATILITY.

     In the past, securities class action litigation has often been brought
against a company following a decline in the market price of its securities.
This risk is especially acute for us because technology companies have
experienced greater than average share price volatility in recent years and, as
a result, have been subject to, on average, a greater number of securities class
action claims than companies in other industries. We may in the future be the
target of similar litigation. Securities litigation could result in substantial
costs and divert management's attention and resources, and could seriously harm
our business.

CONCENTRATION OF OWNERSHIP AMONG OUR EXISTING EXECUTIVE OFFICERS, DIRECTORS AND
PRINCIPAL SHAREHOLDERS MAY PREVENT NEW INVESTORS FROM INFLUENCING SIGNIFICANT
CORPORATE DECISIONS.


     Upon completion of this offering, our executive officers, directors and
principal shareholders will beneficially own, in the aggregate, approximately
76.3% of our outstanding ordinary shares. As a result, these shareholders, if
acting together, will be able to exercise control over all matters requiring
shareholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of control could
disadvantage other shareholders with interests different from those of our
officers, directors and principal shareholders. For example, our officers,
directors and principal shareholders could delay or prevent an acquisition or
merger even if the transaction would benefit other shareholders. Please see
"Principal Shareholders" for a more detailed description of our share ownership.


FAILURE TO RAISE ADDITIONAL CAPITAL OR TO GENERATE THE SIGNIFICANT CAPITAL
NECESSARY TO EXPAND OUR OPERATIONS AND INVEST IN NEW PRODUCTS COULD REDUCE OUR
ABILITY TO COMPETE AND RESULT IN LOWER REVENUES.

     We expect that the net proceeds from this offering, our cash reserves and
any cash flows from operations will be sufficient to meet our working capital
and capital expenditure needs for at least the next 12 months. However, our
limited operating history makes it difficult to predict whether these funds will
be sufficient to finance our anticipated growth. We may need to raise additional
funds if our estimates of revenues or if our working capital or capital
expenditure requirements change or prove inaccurate, if we are required to
respond to unforeseen technological or marketing hurdles or if we choose to take
advantage of unanticipated opportunities. Additional funds might not be
available at acceptable terms, if at all. If additional funds are raised through
the issuance of equity securities, the percentage ownership of our then current
shareholders would be reduced and the value of their investments might decline.
In addition, any new securities issued might have rights, preferences or
privileges senior to those of the securities held by our shareholders. If we
raise additional funds through the issuance of debt, we might become subject to
restrictive covenants.

     If we need additional capital and cannot raise it on acceptable terms and
on a timely basis, we may not be able to, among other things:

     o    develop or enhance our products and services;

     o    acquire new technologies, products or businesses;

     o    expand operations, in the United States or internationally;

     o    hire, train and retain employees; or

     o    respond to competitive pressures or unanticipated capital
          requirements.

     Our failure to do any of these things could result in lower revenues and
could seriously harm our business.


                                       20
<PAGE>


WE MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT IMPROVE OUR
OPERATING RESULTS OR INCREASE THE VALUE OF YOUR INVESTMENT.

     We will have broad discretion in how we use the proceeds from this
offering, and we may spend these proceeds in ways that do not improve our
operating results or increase the value of your investment. You will not have
the opportunity to evaluate the economic, financial or other information on
which we base our decisions regarding how to use the proceeds from this
offering.

WE DO NOT INTEND TO PAY DIVIDENDS ON OUR ORDINARY SHARES.

     We have never declared or paid any cash dividend on our share capital. We
currently intend to retain any future earnings for funding growth and,
therefore, do not expect to pay any dividends in the foreseeable future.

NEW INVESTORS IN OUR ORDINARY SHARES WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL
DILUTION IN THE BOOK VALUE OF THEIR INVESTMENT.

     The initial public offering price of our ordinary shares will be
substantially higher than the net tangible book value per share of our ordinary
shares immediately after this offering. Therefore, if you purchase our ordinary
shares in this offering, you will incur an immediate dilution of $7.21 in net
tangible book value per share of ordinary shares from the price you paid, based
on an assumed initial public offering price of $10.00 per share. The exercise of
outstanding options may result in further dilution. For a further description of
the dilution that you may experience immediately after this offering, please see
"Dilution."

                    RISKS RELATED TO INTERNATIONAL OPERATIONS

WE ARE SUSCEPTIBLE TO ADDITIONAL RISKS FROM INTERNATIONAL OPERATIONS.

     We derived 37% of our revenues in 1999 and 33% of our revenues in the six
months ended June 30, 2000 from sales outside North America. As a result, we
face additional risks from doing business internationally including:

     o    reduced protection of intellectual property rights in some countries;

     o    licenses, tariffs and other trade barriers;

     o    difficulties in staffing and managing foreign operations;

     o    longer sales and payment cycles;

     o    greater difficulties in collecting accounts receivable;

     o    seasonal reductions in business activity;

     o    potentially adverse tax consequences;

     o    laws and business practices favoring local competition;

     o    costs and difficulties of customizing products for foreign countries;

     o    compliance with a wide variety of complex foreign laws and treaties;

     o    political and economic instability; and

     o    variance and unexpected changes in local laws and regulations.

     Our principal research and development facilities are located in Israel,
and our directors, executive officers and other key employees are located
primarily in Israel, the United States and Europe. In addition, we maintain
offices in Germany, Sweden and the United Kingdom to market and sell our
products in those countries and surrounding regions. We have sold XACCTUSAGE
internationally for only a few quarters, and we have limited experience in
developing localized versions of XACCTUSAGE and marketing and distributing them
internationally.

     If we fail to overcome the challenges encountered in our international
operations, we could experience slower than expected revenue growth and our
business could be harmed.

EXCHANGE RATE FLUCTUATIONS BETWEEN THE U.S. DOLLAR AND THE NIS MAY NEGATIVELY
AFFECT OUR EARNINGS.

     Although most of our revenues and a majority of our expenses are
denominated in U.S. dollars, a significant portion of our research and
development expenses are incurred in New Israeli Shekels, or NIS. As a result,
we may be negatively affected by fluctuations in the exchange rate between the
U.S. dollar and the NIS. Further, because most of our international revenues are
denominated in U.S. dollars, a strengthening of the dollar versus other
currencies could make our products less competitive in foreign markets and
collection of receivables more difficult. We do not currently engage in currency
hedging activities but we may choose to do so in the future.

BECAUSE WE HAVE IMPORTANT FACILITIES AND RESOURCES LOCATED IN ISRAEL, ANY MAJOR
ADVERSE DEVELOPMENT IN ITS POLITICAL OR ECONOMIC CONDITIONS COULD CAUSE OUR
BUSINESS TO SUFFER.

     Our principal research and development facilities are located in Israel.
Any major hostilities involving Israel or the interruption or curtailment of
trade between Israel and its present trading partners could significantly harm
our business. Since establishment in 1948, the State of Israel has been and
continues to be in a state of hostility with its neighbors, varying from time to
time in intensity and degree.


     Some of our senior officers and key employees who are citizens and
residents of Israel under the age of 54 are currently or may be obligated to
perform annual reserve duty in the Israeli Defense Forces and are subject to
being called for active military duty at any time. Fulfillment of these
obligations may deprive us of key employees for extended periods of time.


     Further, inflation in Israel and devaluation of the NIS could have an
impact on our financial results. Although Israel has experienced substantially
reduced rates of inflation and devaluation in recent years, they are still
relatively high compared to those in the United States. Our business could be
harmed by inflation or devaluation. If inflation rates in Israel increase again
and hurt Israel's economy as a whole, our operations and financial condition
could suffer.

ANY FUTURE PROFITABILITY MAY BE DIMINISHED IF TAX BENEFITS FROM THE STATE OF
ISRAEL ARE REDUCED OR WITHHELD.


     Pursuant to the Israeli Law for the Encouragement of Capital Investments,
the Israeli government has granted "Approved Enterprise" status to all of our
existing capital investment program in Israel. Consequently, we are eligible for
tax benefits for the first several years in which we generate taxable income.
Our future profitability may be diminished if all or a portion of these tax
benefits are reduced. These tax benefits may be cancelled in the event of
changes in Israeli government policies or if we fail to comply with requisite
conditions and criteria. Currently the most significant conditions that we must
continue to meet include making specified investments in fixed assets,
maintaining the development and production nature of our facilities and
financing at least 30% of these investments through the issuance of share
capital. We may not satisfy these requirements in the future. We cannot assure
you that these tax benefits will be continued in the future at their current
levels, if at all. If these tax benefits were reduced or eliminated, the taxes
we would have to pay are likely to increase.

     In May 2000, an expert committee of the Israeli Ministry of Finance
recommended substantial tax reforms to Israeli tax law which, if adopted, may
increase the amount of tax we have to pay with respect to income derived from
our approved enterprise under the Law for the Encouragement of Capital
Investments, 1959, which may result in lower profitability and a decline in our
share price. Additionally, the proposed tax reforms may change the tax costs
related to employees and as a result increase our employment costs. Please see
"Israeli Taxation" for a further discussion of tax issues under Israeli Law.


ISRAELI COURTS MIGHT NOT ENFORCE JUDGMENTS RENDERED OUTSIDE OF ISRAEL, WHICH MAY
MAKE IT DIFFICULT TO COLLECT ON JUDGMENTS RENDERED AGAINST US.

     Some of our directors and executive officers are not residents of the
United States and some of their assets and our assets are located outside the
United States. Service of process upon our non-U.S. resident directors and
executive officers and the enforcement of judgments obtained in the United
States against us, and our directors and executive officers outside of the
United States, may be difficult to obtain. XACCT Technologies, Inc., our U.S.
subsidiary, is the U.S. agent authorized to receive service of process in any
action against us in any federal or state court arising out of this offering or
any related purchase or sale of securities. We have not given consent for this
agent to accept service of process in connection with any other claim.


                                       22
<PAGE>


     We have been informed by our legal counsel in Israel that there is doubt as
to the enforceability of civil liabilities under U.S. securities laws in
original actions instituted in Israel. Moreover, an Israeli court generally will
not enforce a foreign judgment if it was given in a state whose laws do not
provide for the enforcement of judgments of Israeli courts or if its enforcement
is likely to prejudice the sovereignty, the law, public policy or the security
of the State of Israel. An Israeli court also will not declare a foreign
judgment enforceable if:

     o    the judgment was obtained by fraud;

     o    adequate service of process was not effected or the defendant did not
          have a reasonable opportunity to present his or her arguments and
          evidence;

     o    the judgment was rendered by a court not competent to render it
          according to the laws of private international law in Israel;

     o    the judgment is at variance with another judgment that was given in
          the same matter between the same parties and which is still valid; or

     o    at the time the action was brought in the foreign court a suit in the
          same matter and between the same parties was pending before a court or
          tribunal in Israel.

WE HAVE ADOPTED ANTI-TAKEOVER PROVISIONS THAT COULD DELAY OR PREVENT AN
ACQUISITION OF XACCT, EVEN IF AN ACQUISITION WOULD BE BENEFICIAL TO OUR
SHAREHOLDERS.

     Our articles of association provide for a staggered board of directors and
the ability of our board of directors to issue, without further shareholder
action, preferred shares with rights and privileges which may be senior to our
ordinary shares. These provisions may inhibit or may have the effect of
delaying, preventing or making more difficult a merger or other acquisition of
XACCT, even if doing so would be beneficial to our shareholders. Please see
"Description of Share Capital--Anti-Takeover Provisions Under Israeli Law" for a
further discussion of anti-takeover provisions.

ISRAELI LAW CONTAINS CERTAIN ANTI-TAKEOVER PROVISIONS THAT COULD DELAY OR
PREVENT AN ACQUISITION OF XACCT, EVEN IF AN ACQUISITION WOULD BE BENEFICIAL TO
OUR SHAREHOLDERS.

     Israeli law regulates mergers, votes required to approve a merger,
acquisition of shares through tender offers and transactions involving
significant shareholders in a manner that may discourage or delay potential
acquisition proposals, even if they are beneficial to our shareholders. Please
see "Description of Share Capital--Anti-Takeover Provisions Under Israeli Law"
for a further discussion of anti-takeover provisions.

THE NEW ISRAELI COMPANIES LAW IMPOSES SUBSTANTIAL DUTIES ON SHAREHOLDERS AND MAY
CAUSE UNCERTAINTIES REGARDING CORPORATE GOVERNANCE.

     The Israeli Companies Law, which became effective on February 1, 2000,
brought about significant changes to Israeli corporate law. The new law includes
provisions imposing substantial duties on certain controlling and
non-controlling shareholders. Please see "Management--Approval of Certain
Transactions--Duties of Shareholders" for a more detailed discussion of
shareholder duties under the Companies Law. In addition, uncertainties regarding
certain aspects of corporate governance may persist until Israeli courts
adequately interpret the Companies Law. These uncertainties could inhibit
takeover attempts, other transactions and other corporate decisions and actions
that may be beneficial to shareholders.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements in "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Business" and elsewhere. These statements
relate to future events or our future financial performance. In some cases, you
can identify forward-looking statements by terminology such as "may," "will,"
"should," "expect," "plan," "anticipate," "believe," "estimate," "predict,"
"potential" or "continue" or the negative of these terms or other comparable
terminology. These statements are only predictions and involve known and unknown
risks, uncertainties and other factors, including the risks outlined under "Risk
Factors," that may cause our or our industry's actual results, levels of
activity, performance or achievements to be materially different from any future
results, levels of activity, performance or achievements expressed or implied by
these forward-looking statements.

     Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, levels of
activity, performance or achievements. Moreover, neither we nor any other person
assume responsibility for the accuracy and completeness of these statements. We
are under no duty to update any of the forward-looking statements after the date
of this prospectus to conform these statements to actual results.

                                 USE OF PROCEEDS

     We estimate that we will receive approximately $44.1 million in net
proceeds from this offering, based upon the sale of 5 million shares of ordinary
shares at an assumed initial public offering price of $10.00 per share, the
midpoint of the offering range on the cover of this prospectus, after deducting
underwriting discounts and commissions and estimated offering expenses payable
by us. If the underwriters exercise their over-allotment option in full, our net
proceeds will be approximately $51.1 million.


     We intend to use the net proceeds of this offering for additional working
capital and other general corporate purposes. We have not yet determined our
expected use of the proceeds, but we currently estimate that through June 2001
we will use approximately $10.0 million to $12.0 million on research and
development expenditures. We will also use a portion of the proceeds for
expansion of our operations and sales and marketing capabilities, and the
capital requirements to support these expansions, primarily including computing
equipment, furniture and fixtures. Other than noted above, we currently do not
have any specific plans on the allocation of the proceeds, and therefore the
proceeds we receive from this offering do not necessarily correlate with our
expansion.


     The actual amount of net proceeds that we spend on a particular use will
depend on a variety of factors, many of which are beyond our control. These
factors include our future revenue growth, if any, additional financing sources,
if any, the availability and desirability of potential acquisitions of
businesses, products or technologies, the amount of expenditures required for
other uses and the amount of cash generated or used by our operations. Many of
these factors are beyond our control. As a result, our management will retain
broad direction in the use of the net proceeds from this offering.

     Until we use the net proceeds of this offering, we intend to invest the net
proceeds in short-term, investment-grade marketable securities.

     We are also conducting an initial public offering at this time to position
ourselves more strongly in our market, to create a public market for our
ordinary shares and to facilitate our future access to the public capital
markets.


                                 DIVIDEND POLICY

     We have not declared or paid any cash dividends on our ordinary shares in
the past. We do not expect to pay any cash dividends on our ordinary shares in
the foreseeable future and intend to retain our future earnings, if any, to
finance the development of our business.

     In the event that cash dividends are declared in the future, we will pay
those dividends in New Israeli Sheckels, or NIS, or in foreign currency, subject
to any statutory limitations. Under current Israeli regulations, any dividends
or other distributions paid with respect to ordinary shares will be freely
repatriable in such non-Israeli currencies at the rate of exchange prevailing at
the time of conversion, provided that Israeli income tax has been paid on, or
withheld from, those payments. Because exchange rates between the NIS and the
U.S. dollar fluctuate, a U.S. shareholder will bear the risks of currency
fluctuations during the period between the date the dividend is declared and
paid by us in NIS and the date conversion is made by the shareholder into U.S.
dollars.

     The following table sets forth our capitalization as of June 30, 2000:

     o    on an actual basis;

     o    on a pro forma basis giving effect to (1) the exercise of warrants

          at a weighted average exercise price of $7.72 per share, which
          warrants if unexercised would expire upon the closing of this
          offering; and (2) the conversion of all issued and outstanding
          preferred shares into ordinary shares; and

     o    on a pro forma as adjusted basis to reflect the sale of the ordinary
          shares in this offering at an assumed initial public offering price of
          $10.00 per ordinary share after deducting estimated underwriting
          discounts and the estimated expenses of this offering payable by us.

                                    DILUTION

     If you invest in our ordinary shares, your interest will be diluted to the
extent of the difference between the public offering price per share of our
ordinary shares and the pro forma as adjusted net tangible book value per share
of our ordinary shares immediately after this offering.

     Investors participating in this offering will incur immediate, substantial
dilution. The pro forma net tangible book value of our ordinary shares as of
June 30, 2000 was $31.3 million, or $1.42 per ordinary share. Pro forma net
tangible book value per share represents the amount of our total tangible assets
less total liabilities, divided by the number of ordinary shares outstanding
after assuming the exercise of warrants to purchase 1,398,547 preferred shares
outstanding as of June 30, 2000, which warrants if unexercised would expire upon
the completion of this offering and the conversion of all issued and
outstanding preferred shares into ordinary shares. Assuming our sale of ordinary
shares offered by this prospectus at an assumed initial public offering price of
$10.00 per share and after deducting the estimated underwriting discounts and
commissions and estimated offering expenses payable, our pro forma as adjusted
net tangible book value at June 30, 2000 would have been $75.4 million, or $2.79
per ordinary share. This represents an immediate increase in pro forma net
tangible book value of $1.37 per share to existing shareholders and an immediate
dilution of $7.21 per share to new investors purchasing ordinary shares in this
offering. The following table illustrates this dilution on a per ordinary share
basis:

     The foregoing discussion and tables exclude:

          outstanding as of June 30, 2000 to purchase, at a weighted average
          exercise price of $2.51 per share;

     o    8,693,148 ordinary shares available for future issuance under our
          share option plans; and

     o    750,000 ordinary shares that will be available for issuance under our
          2000 Employee Share Purchase Plan.

     To the extent any of these options are exercised or any of these shares are
issued, there will be further dilution to new investors.

     If the underwriters' over-allotment option is exercised in full, the number
of shares held by new investors increase to 5,750,000, or 20.7% of the total
ordinary shares outstanding after this offering.

                      SELECTED CONSOLIDATED FINANCIAL DATA
                 (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

     The following selected consolidated financial data as of December 31, 1998
and 1999 and for the period from our inception in June 1997 through December 31,
1997 and for the years ended December 31, 1998 and 1999 have been derived from
our consolidated financial statements and the related notes set forth elsewhere
in this prospectus. These consolidated financial statements have been prepared
in accordance with generally accepted accounting principles in the United
States. The selected consolidated financial data as of December 31, 1997 have
been derived from audited consolidated financial statements not included in this
prospectus, which have also been prepared in accordance with generally accepted
accounting principles in the United States. The selected consolidated statements
of operations data for the six months ended June 30, 1999 and 2000 and the
consolidated balance sheet data at June 30, 2000 have been derived from
unaudited financial statements included elsewhere in this prospectus. The
unaudited financial statements have been presented on the same basis as the
audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, that we consider necessary for
a fair presentation of our financial position at those dates and the results of
operations for those periods. You should read the selected consolidated
financial data set forth below in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations," and our consolidated
financial statements and the related notes included elsewhere in this

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

     YOU SHOULD READ THE FOLLOWING DISCUSSION AND ANALYSIS IN CONJUNCTION WITH
THE "SELECTED CONSOLIDATED FINANCIAL DATA" AND OUR CONSOLIDATED FINANCIAL
STATEMENTS AND THE RELATED NOTES APPEARING ELSEWHERE IN THIS PROSPECTUS. WE
BELIEVE THAT PERIOD-TO-PERIOD COMPARISONS OF OUR RESULTS OF OPERATIONS ARE NOT
NECESSARILY MEANINGFUL AND SHOULD NOT BE RELIED UPON AS INDICATIONS OF FUTURE
PERFORMANCE.

OVERVIEW

     We are a provider of business infrastructure software for network service
providers. Our infrastructure software is designed to allow network service
providers to implement new value-based and usage-based business models and to
offer higher-margin, enhanced services through comprehensive real-time data
collection, data aggregation and automated service provisioning.

     Our software is designed to gather network usage, traffic and transaction
information from network elements such as routers, switches, firewalls, servers
and gateways and to synthesize, enhance and tailor that information to produce
the specified information and formats required by network service providers to
implement these business models. Network service providers can use this
real-time data to offer and charge their customers appropriately for network
services based on usage time, quality of service, transactions, events, content
or volume. These network services include Internet telephony, web hosting,
application renting, video conferencing, movies/video on demand, audio over
Internet protocol, unified messaging, network games, virtual private networking,
voice-mail, fax over Internet protocol, e-mail and file transfers. This detailed
information can also be used to support operations and business support systems
of network service providers, including billing, customer care, price modeling,
customer retention, fraud management, service level verification and other
systems. We have designed our solution to provide the carrier-class scalability,
reliability, manageability and flexibility that our customers demand to run
their mission-critical business applications.

     We were incorporated in Israel and commenced operations in June 1997. We
were a development stage company from our inception in June 1997 through
December 1998. We began shipping our initial product in January 1999. We have
spent a substantial amount to date developing our initial products and
establishing our operations. From our incorporation in June 1997 through the end
of 1998, we primarily engaged in research activities and development of our
products. We first began generating revenue from software license fees from the
initial version of our products in January 1999. During 1999, we continued to
enhance the functionality of our products and build our management team and
operations. During the first two quarters of 2000 we added 26 customers and
hired 111 employees. As our revenue increased we also incurred significant
operating expenses as we expanded our research and development organization, our
direct sales force and professional services department. At June 30, 2000, we
had an accumulated deficit of $30.9 million.

     We derive our revenue principally from software licenses and related
services. To date, our license revenues have been derived from licenses of
XACCTUSAGE, our server-based software platform that resides at the network
service provider's site, as well as information source modules and gatherers
which reside near the switches, routers, hubs and other elements of the network.
Revenue from license fees is recognized when persuasive evidence of an agreement
exists, delivery of the product has occurred, no significant XACCT obligations
with regard to implementation remain, the fee is fixed or determinable, and
collectibility is probable. We generally do not grant a right of return to our
customers. When a right of return exists, we defer revenue until the right of
return expires, at which time revenue is recognized provided that all other
revenue recognition criteria have been met. We consider all arrangements with
payment terms extending beyond thirty days not to be fixed or determinable. If
the fee is not fixed or determinable, revenue is recognized as payments become
due from the customers provided that all other revenue recognition criteria have
been met. Customer payments received prior to the recognition of revenues are
recorded as deferred revenue.

     When contracts contain multiple elements wherein vendor specific objective
evidence (VSOE) of fair value exists for all undelivered elements, we account
for the delivered elements in accordance with the "Residual Method" prescribed
by Statement of Position No. 98-9. Service revenue includes maintenance and
support, consulting and training. Customers who license our products usually
purchase maintenance and support contracts. These contracts provide unspecified
software upgrades, as well as technical support, over a specified term, which
typically is 12 months. Maintenance contracts are usually paid in advance, and
revenues from these contracts are recognized on


                                       30

<PAGE>


a straight-line basis over the term of the contract. Customers typically
purchase additional consulting services from us to support their implementation
activities. These consulting services generally are sold on a time and materials
basis. Consulting and training revenue are recognized at the time the services
are rendered. Customer advances and billed amounts due from customers in excess
of recognized revenues are recorded as deferred revenues. Arrangements that
include consulting services are evaluated to determine whether those services
are essential to the functionality of other elements of the arrangement. When
services are considered essential, revenue under the arrangement is recognized
using contract accounting. When services are not considered essential, the
revenue allocable to the software services is recognized as the services are
performed. To date, we have determined that the services are not essential to
the functionality of the other elements of the arrangements.

     We market our products through our direct sales force and through
relationships with system integrators, value-added resellers and technology
vendors. Revenues attributable to indirect sales are recognized upon acceptance
by the end customer. In 1999, we derived 63% of our revenue from customers
located in North America and 37% of our revenue from customers outside North
America, substantially all of which were in Europe. In the six months ended June
30, 2000, we derived 67% of our revenue from customers in North America and 33%
of our revenue from customers located outside North America. Please see note 9
to our consolidated financial statements for additional financial information
presented by geographic area. In the first two quarters of 2000, we opened three
offices in Europe. We plan to expand our operations into Asia and further across
Europe.

     Our limited operating history makes it difficult to predict our future
operating results. We believe our future success will depend on our ability to
expand our customer base and enhance our products. We intend to continue to
invest significantly in sales, marketing and research and development and expect
to incur operating losses for the foreseeable future. A delay in the revenue
recognition from one or more license transactions could cause significant
variations in operating results from quarter to quarter and could result in
larger-than-anticipated losses.

     In 1999, a small number of customers accounted for a significant portion of
our total revenues. During that year, revenues from four customers accounted for
51% of total revenues. We expect that revenues from a limited number of
customers will continue to account for a large percentage of total revenues in
future quarters. TV Cabo Acoreana, S.A., UUNET Technologies, Inc., Genuity Inc.,
and Verio Inc. each accounted for at least 10% of total revenues in 1999. For
the six months ended June 30, 2000, Digital Island, Cable & Wireless, PLC, CPG
and WorldCom, Inc. each accounted for at least 10% of total revenues.

     We intend to continue to invest in product development and technologies to
enhance our products and services and develop new products and services. Also,
an important part of our strategy is to expand our operations and employee base
and build our sales, marketing, customer support, technical and operational
resources. We expect to continue to incur substantial operating losses in the
future, and our expected increase in operating expenses will require significant
increases in revenue before we become profitable.

     STOCK-BASED COMPENSATION

     Deferred stock compensation represents the difference between the estimated
fair value of the ordinary shares for accounting purposes and the option
exercise price at the date of grant. We have amortized deferred stock
compensation of $3.6 million in connection with stock options we have granted
through June 30, 2000. Approximately $11.4 million is to be amortized over the
remaining vesting period of the options. This amount is amortized over the
four-year vesting period of the options using the graded vesting option
approach. We expect to record additional deferred stock compensation with
respect to share option grants made subsequent to June 30, 2000. Deferred stock
compensation expense will be reduced for future periods to the extent that
options are terminated prior to full vesting. Please see note 7 to our
consolidated financial statements for a further description of stock-based
compensation expense.

     NET OPERATING LOSS CARRYFORWARDS

     From our inception in June 1997 through December 31, 1999, we had $4.7
million of Israeli net operating loss carryforwards and $6.9 million of U.S.
federal and state net operating loss carryforwards to offset future taxable
income. These net operating loss carryforwards expire in varying amounts from
2006 to 2019. Given our limited operating history and our losses incurred to
date, coupled with the difficulty of forecasting future results, a full
valuation allowance has been recorded. Furthermore, as a result of changes in
our equity ownership from our preferred share offerings and this offering, use
of net operating losses and tax credits may be subject to substantial


                                       31

<PAGE>


annual limitations. This is due to the ownership change limitations provided in
the United States Internal Revenue Code and similar state provisions. The degree
of any such limitation cannot presently be estimated. To date, we have not
performed an evaluation to determine if such a limitation exists, and we may not
perform that evaluation until and unless we are profitable in the future. The
annual limitation may result in the expiration of net operating losses and tax
credits before utilization. Please see note 8 to our consolidated financial
statements for a further discussion of net operating loss carryforwards.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1999 AND JUNE 30, 2000

     REVENUE

     Total revenue increased $2.3 million or 717% from $315,000 for the six
months ended June 30, 1999 to $2.6 million for the six months ended June 30,
2000. This increase was primarily attributable to the increase in the number of
customers. In the first six months of 1999, we generated revenue from 18
customers and in the first six months of 2000, we generated revenue from 44
customers. This increase was because of greater market acceptance of our
software products. The average license revenue transaction size also increased
from approximately $32,000 for the six months ended June 30, 1999 to
approximately $95,000 for the six months ended June 30, 2000.

     LICENSE. License revenue increased $1.8 million or 676% from $267,000 for
the six months ended June 30, 1999 to $2.1 million for the six months ended June
30, 2000. This increase was primarily attributable to the continued growth of
our revenue since the first two quarters of 1999, the initial quarters in which
we licensed our products.

     SERVICE. Service revenue increased $456,000 or 950% from $48,000 for the
six months ended June 30, 1999 to $504,000 for the six months ended June 30,
2000. This increase was primarily attributable to the increased implementation
and consulting services performed and the growth in number of maintenance
contracts.

     COST OF REVENUE

     Total cost of revenue increased $1.5 million or 2321% from $64,000 for the
six months ended June 30, 1999 to $1.6 million for the six months ended June 30,
2000. This increase was primarily attributable to the growth in our professional
services organization.

     LICENSE. Cost of license revenue consists primarily of expenses incurred to
manufacture, package and distribute software products and related documentation
and license fees paid to third parties under technology license arrangements.
Cost of license revenue increased $209,000 or 1306% from $16,000 for the six
months ended June 30, 1999 to $225,000 for the six months ended June 30, 2000.
For the first six months of June 30, 2000, cost of license revenue increased
primarily attributable to increased licensing of third-party technologies. We
expect cost of license revenue to grow in absolute dollars as we continue to
license third-party technologies.

     SERVICE. Cost of services revenue includes salaries and other expenses from
our professional services and customer support organization and related overhead
expenses. Cost of service revenue increased $1.3 million or 2660% from $48,000
for the six months ended June 30, 1999 to $1.3 million for the six months ended
June 30, 2000. This increase was primarily attributable to the growth in the
number of employees in our professional services and customer support
organizations which grew from 6 employees at June 30, 1999 to 36 employees at
June 30, 2000. Cost of services revenue exceeded services revenue during the six
months ended June 30, 2000 because of the investment in our services
organization. We expect to continue to invest heavily in professional services
and customer support, consulting and training and expect cost of services
revenue to increase.

     OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses include
salaries and related payroll and facilities expenses for engineering and
technical personnel in addition to purchased software used for product
development. We expense all of these costs as incurred. Research and development
expenses increased $3.0 million or 299% from $1.0 million for the six months
ended June 30, 1999 to $4.0 million for the six months ended June 30, 2000. This
increase was primarily because of the growth in the number of engineering
personnel from 22 employees at June 30, 1999 to 71 employees at June 30, 2000.
We expect research and development expense to increase in


                                       32

<PAGE>


absolute dollars in the future as we continue to hire additional research and
development personnel and spend additional amounts on enhancement of existing
products and development of new products.

     SALES AND MARKETING. Sales and marketing expenses consist of salaries,
commissions and related overhead expenses for sales and marketing personnel,
promotional expenses and travel expenses. Sales and marketing expenses increased
$6.2 million or 258% from $2.4 million for the six months ended June 30, 1999 to
$8.6 million for the six months ended June 30, 2000. The increase was largely
due to increased personnel and personnel-related costs associated with the
hiring of additional sales and marketing personnel, increased commissions paid
resulting from higher sales and increased marketing promotions such as trade
show participation. We increased our sales and marketing personnel from 26
employees at June 30, 1999 to 66 at June 30, 2000. We also incurred additional
expenses during the first quarter of 2000 as we increased the number of regional
and international sales offices. We expect that sales and marketing expense will
continue to be a significant component of operating expense. We expect sales and
marketing expense will increase in absolute dollars as we increase our sales and
marketing activities.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist of
salaries for administrative, legal, executive and finance personnel and related
overhead expenses, recruiting costs and professional service fees for legal,
accounting and other professional services. General and administrative expenses
increased $2.1 million or 484% from $429,000 for the six months ended June 30,
1999 to $2.5 million for the six months ended June 30, 2000. The increase was
primarily because of the growth in the number of general and administrative
personnel from 5 employees at June 30, 1999 to 30 employees at June 30, 2000. We
expect general and administrative expense to increase as we hire additional
personnel to support the anticipated growth of our business and our operations
as a public company.

     AMORTIZATION OF DEFERRED STOCK COMPENSATION. We did not amortize any
deferred stock compensation expense for the six months ended June 30, 1999. We
have recorded deferred stock-based compensation for stock options granted to
employees and consultants through June 30, 2000 of approximately $11.8 million.
Of this amount, we amortized approximately $3.2 million through June 30, 2000.
The remaining deferred stock compensation balance and an additional amount of
stock-based compensation from grants from June 30, 2000 through July 12, 2000 of
approximately $3.4 million will be amortized over the remaining vesting period
of the options. Based on option grants through July 12, 2000, we expect to
amortize approximately $2.4 million in the third quarter of 2000 and $2.2
million in the fourth quarter of 2000. We expect to recognize lower amounts in
subsequent quarters.

     INTEREST AND OTHER INCOME, NET. Interest and other income, net consist
primarily of interest received on invested cash balances. Interest and other
income, net increased $552,000 or 484% from $114,000 for the six months ended
June 30, 1999 to $666,000 for the six months ended June 30, 2000 primarily due
to higher cash balances in the year following equity financings completed in
October 1999 and March 2000.

INCEPTION (JUNE 1997) TO DECEMBER 31, 1998 AND YEAR ENDED DECEMBER 31, 1999

     REVENUES

     LICENSE. We recorded no license revenues for the period from our inception
in June 1997 to December 31, 1998. License revenues in 1999 were $898,000
following the commercial release of our initial product in the fourth quarter of
1998 and the initiation of sales activities.

     SERVICE. We recorded no revenues for the period from our inception to
December 31, 1998. Service revenues in 1999 totaled $296,000. This increase was
primarily because of maintenance on new licenses and increased implementation
and consulting services performed in conjunction with increased license sales in
1999.

     COST OF REVENUES

     LICENSE. We recorded no cost of license revenues for the period from our
inception to December 31, 1998. We incurred $48,000 in cost of license revenues
in 1999 primarily for the packaging and documentation costs to distribute our
software.

     SERVICE. We recorded no cost of service revenues for the period from our
inception to December 31, 1998. We incurred $192,000 in cost of service revenues
in 1999 to support the installation and implementation of our software and as we
expanded our professional service organization.

     OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses increased
$342,000 or 18% from $1.9 million for the period from our inception to December
31, 1998 to $2.2 million in 1999. The increase was primarily attributable to the
hiring of additional engineering personnel.

     SALES AND MARKETING. Sales and marketing expenses increased $4.4 million or
205% from $2.1 million for the period from our inception to December 31, 1998 to
$6.5 million in 1999. The increase was attributable primarily to increased sales
and marketing efforts and higher sales commissions resulting from increased
sales.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses were $1.2
million in the period from our inception to December 31, 1998 and remained flat
at $1.2 million in 1999.

     AMORTIZATION OF DEFERRED STOCK COMPENSATION. We recorded no deferred stock
compensation in the period from our inception to December 31, 1998. We recorded
$3.2 million in deferred stock compensation in 1999 and amortized $381,000 of
deferred stock compensation expense in 1999.

     INTEREST AND OTHER INCOME, NET. Interest and other income, net increased
$156,000 or 139% from $112,000 for the period from our inception to December 31,
1998 to $268,000 in 1999 as a result of higher average cash balances.

SIX QUARTERS ENDED JUNE 30, 2000

     We first began shipping products in the first quarter of 1999 and, as a
result, we believe that annual comparisons of our operating results and
quarterly results of operations involving periods prior to December 31, 1998 are
less meaningful than an analysis of recent quarterly operating results.
Accordingly, we are providing a discussion and analysis of our quarterly
operating results for the six quarters ended June 30, 2000.

     The following tables list the operating results for the six most recent
quarters as well as, for the periods indicated, each line item as a percentage
of total revenues. We believe this unaudited information has been presented on
the same basis as our annual consolidated financial statements and includes all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the unaudited information for the quarters presented. This
information should be read together with the consolidated financial statements
and the related notes included elsewhere in this prospectus. The operating
results for any quarter are not necessarily indicative of the results for any
future period.

     REVENUES

     Total revenues increased sequentially on a quarterly basis from $85,000 for
the quarter ended March 30, 1999 to $1.5 million for the quarter ended June 30,
2000. We began to generate revenues in 1999 following the commercial release of
our initial product in the fourth quarter of 1998. These revenues grew
sequentially through the six quarters ended June 30, 2000 as our customer base
and our average transaction size increased. Our customer base increased from 11
at March 30, 1999 to 52 at June 30, 2000. Average transaction size increased
from approximately $22,000 in the quarter ended March 30, 1999 to approximately
$95,000 in the quarter ended June 30, 2000, primarily as a result of larger
initial deployments by our customers.

     LICENSE. License revenues increased sequentially on a quarterly basis from
$81,000 for the quarter ended March 30, 1999 to $1.2 million for the quarter
ended June 30, 2000 resulting from increased sales of our software products as a
result of the expansion of our direct sales force.

     SERVICE. Service revenues increased from $4,000 for the quarter ended March
30, 1999 to $301,000 for the quarter ended June 30, 2000. This increase resulted
primarily from increased software licenses following the introduction of our
products and the expansion of our professional service organization.

     COST OF REVENUES

     Total cost of revenues increased sequentially on a quarterly basis from
$22,000 for the quarter ended March 30, 1999 to $1.0 million for the quarter
ended June 30, 2000.

     LICENSE. Cost of license revenues has grown sequentially since the
beginning of 1999 to support increased software licenses following the
introduction of our initial product. We expect that cost of license revenues
will increase in dollar amounts but remain relatively flat as a percentage of
total revenues in the long term.

     SERVICE. Cost of service revenues increased sequentially on a quarterly
basis since the beginning of 1999. This increase was due primarily to our hiring
of additional service personnel in anticipation of supporting larger service
obligations necessary to support a larger customer base. This investment
substantially increased cost of service revenues as a percentage of service
revenue in the third quarter of 1999. We expect that cost of service revenues
will continue to increase in dollar amount as we continue to expand our customer
support organization in advance of anticipated customer demand.

     OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses increased from
$529,000 for the quarter ended March 30, 1999 to $2.2 million for the quarter
ended June 30, 2000 primarily due to the hiring of 49 additional engineering
personnel during the six quarters ended June 30, 2000 to support new product
development and product enhancements. We intend to spend significant amounts on
enhancing existing products and developing new products. As a result, we
anticipate that research and development expenses will increase significantly in
dollar amounts in future periods.

     SALES AND MARKETING. Sales and marketing expenses increased from $1.1
million for the quarter ended March 30, 1999 to $4.8 million for the quarter
ended June 30, 2000 primarily due to increased personnel and personnel-related
costs associated with our hiring of additional sales and marketing personnel due
to the expansion of our direct sales force, increased commissions paid resulting
from higher sales and increased marketing promotions such as trade show
participation. We increased our sales and marketing department from 34 employees
at December 31, 1998 to 66 employees at June 30, 2000. We anticipate that sales
and marketing expenses will increase significantly in dollar amounts as we
continue to expand our sales and marketing organization and programs.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses increased
from $194,000 in the quarter ended March 30, 1999 to $1.4 million in the quarter
ended June 30, 2000. This sequential increase was primarily attributable to
increased personnel and personnel-related costs associated with the hiring of
additional administrative and finance personnel, and higher recruiting and
professional service fees. We believe that our general and administrative
expenses will continue to increase in dollar amounts as our operations grow and
as we incur the expenses associated with operating as a public company.

     AMORTIZATION OF DEFERRED STOCK COMPENSATION. We amortized stock
compensation expense of $3.6 million in the six quarters ended June 30, 2000.

     INTEREST AND OTHER INCOME, NET. Interest and other income, net increased
from $95,000 in the quarter ended March 31, 1999 to $497,000 in the quarter
ended June 30, 2000 primarily due to higher cash balances in the two quarters
ended June 30, 2000 following equity financings completed in October 1999 and
March 2000.

     The amount and timing of our expenses generally will vary from quarter to
quarter depending on our level of actual and anticipated business activities.
For example, sales and marketing expenses in the fourth quarter typically
reflect higher commission payments as a result of higher commission rates after
achievement of yearly target sales levels and increased marketing expenses
related to significant industry trade shows held during various times during the
year. Our revenues and operating results are difficult to forecast and will
fluctuate, and we believe that period-to-period comparisons of our operating
results will not necessarily be meaningful. Additionally, as a strategic
response to a changing competitive environment, we may elect from time to time
to make certain pricing, service, marketing or acquisition decisions that could
have a negative impact on our financial performance. Our past operating history
has shown that a significant percentage of our quarterly revenues are realized
toward the end of a quarter. A delay in the completion of a sale past the end of
a particular quarter could negatively impact results for that quarter. Our
future quarterly operating results may not meet the expectations of securities
analysts or investors in any given quarter, which would likely cause the price
of our ordinary shares to decline.

LIQUIDITY AND CAPITAL RESOURCES

     Since our inception, we have financed our operations primarily through the
private sale of $51.8 million of our securities. We anticipate that we will
receive $10.8 million on or prior to the closing of this offering from the
exercise of outstanding warrants for the purchase of 1,398,547 ordinary shares
at a weighted average exercise price of $7.72 per share, which warrants expire
upon the completion of this public offering.

     Net cash used in operating activities was $8.2 million for the period ended
December 31, 1999 and $11.7 million for the six months ended June 30, 2000 and
was primarily attributable to net losses during these periods and increases in
trade receivables, year-to-year.

     Net cash used in investing activities was $1.5 million for the period ended
December 31, 1999 and $2.0 million for the six months ended June 30, 2000. Net
cash used in investing activities for the six months ended June 30, 2000
consists primarily of the purchase of capital expenditures partially offset by
proceeds from the sale of

                                       36

<PAGE>

marketable securities. In 1999, net cash used in investing activities consists
primarily of the purchase of capital expenditures and investment in marketable
securities. The majority of our capital investments were for computer hardware
and software and office furniture and equipment.

     Net cash provided by financing activities was $21.6 million for the period
ended December 31, 1999 and $16.3 million for the six months ended June 30,
2000. Net cash provided by financing activities consists primarily of net
proceeds from the issuance of preferred shares and the exercise of warrants for
both periods.

     We expect to experience significant growth in our operating expenses for
the foreseeable future in order to execute our business plan. As a result, we
anticipate that operating expenses and planned capital expenditures will
constitute a material use of our cash resources. In addition, we may use cash
resources to fund acquisitions or investments in other businesses, technologies
or product lines. We believe that available cash and cash equivalents, the net
proceeds from this offering and the exercise of warrants upon closing of this
offering and any cash flows from operations, will be sufficient to meet our
working capital and operating expense requirements for at least the next 12
months. However, we may require additional funds to support our working capital
and operating expense requirements or for other purposes and may seek to raise
these additional funds through public or private debt or equity financings. We
cannot assure you that this additional financing will be available, or if
available, will be available on reasonable terms and not dilutive to our
shareholders.

YEAR 2000 COMPLIANCE

     We have not experienced any Year 2000-related disruption in our products
and the operation of our systems. To our knowledge, none of our material
suppliers or vendors experienced any material Year 2000 problems. Although most
Year 2000 problems should have become evident on January 1, 2000 or February 29,
2000, additional Year 2000-related problems may become evident in the future.

TAXATION

     Our tax rate will reflect a mix of the United States statutory tax rate on
our United States income and the Israeli tax rate discussed below. We expect
that most of our taxable income will be generated in Israel. Israeli companies
are generally subject to corporate income tax at the rate of 36%. However, the
effective rate of tax of a company that derives income from an approved
enterprise, as discussed below, may be considerably lower.

     Our production facilities have been granted approved enterprise status
pursuant to the Israeli Law for the Encouragement of Capital Investments,
5719-1959, referred to as the Investment Law. The primary tax benefits resulting
from approved enterprise status are described below.

     Income derived from our approved enterprise is tax exempt for two years of
the ten-year tax benefit period, and is subject to a reduced tax rate of 10% to
25%, depending on the rate of non-Israeli investments in the company, during the
remainder of the period. The tax benefit period for this approved enterprise has
not yet commenced. The tax benefit period will commence in the year in which we
first recognize Israeli taxable income. The tax benefit period is subject to
limits of the earlier of 12 years from the commencement of production, or 14
years from receipt of the approval.

     In the period from our inception in June 1997 through December 31, 1997, in
the years ended December 31, 1998 and 1999 and in the six months ended June 30,
2000, we incurred losses for tax purposes. Accordingly, we did not provide for
taxes on income in any of the reported periods.

     In May 2000, an expert committee of the Israeli Ministry of Finance
recommended substantial tax reforms to Israeli tax law which, if adopted, may
increase the amount of the tax we have to pay with respect to income derived
from our approved enterprise under the Law for the encouragement of Capital
Investments, 1959, which may result in lower profitability and a decline in our
share price. Additionally, the proposed tax reforms may change the tax costs to
employees and as a result increase our employment cost. Please see "Israeli
Taxation" for a further discussion of tax issues under Israeli Law.

INFLATION AND MARKET RISK

     Most of our sales historically have been made in U.S. dollars, and most of
our expenses have been incurred in U.S. dollars or denominated in NIS which is
linked to the dollar. We have not been materially affected by currency
fluctuations between the NIS and the U.S. dollar or by the Israeli rate of
inflation.

     We do not currently use financial instruments for trading or hedging
purposes and do not currently hold any derivative financial instruments which
could expose us to significant market risk. We invest our funds primarily in
low-risk, short-term banking instruments yielding fixed interest rates.

FUNCTIONAL CURRENCY

     The U.S. dollar is the primary currency in the economic environment in
which we and our subsidiaries operate. Substantially all of our sales are made
outside of Israel and are denominated in U.S. dollars. Most of our expenses,
including marketing and service costs, are made outside of Israel and are
incurred in U.S. dollars. As a result, our functional currency is the U.S.
dollar.

                                    BUSINESS

OVERVIEW

     We are a provider of business infrastructure software for next-generation
networks. Our customers primarily consist of telecommunication carriers,
Internet service providers, enterprise network operators, wireless service
providers and cable network operators, which we refer to as network service
providers. Network service providers use our software's comprehensive real-time
data collection, data aggregation and automated service provisioning
capabilities to deploy new business models and higher-margin, enhanced services.
Our solution serves as a software infrastructure for network service providers
that enables the collection and aggregation of network usage, traffic and
transaction data from network elements such as routers, switches, firewalls,
servers and gateways and the synthesis of that data into the information and
formats required by the billing, customer care, price modeling, customer
retention, fraud management, service level verification and other operations and
business support systems of network service providers. Network service providers
can use the gathered real-time data to offer and charge appropriately for
network services based on usage time, quality of service, transactions, events,
content or volume. These network services include Internet telephony, web
hosting, application renting, video conferencing, movies/video on demand, audio
over Internet protocol, unified messaging, network games, virtual private
networking, voice-mail, fax over internet protocol, e-mail and file transfers.
This detailed network information can also be used to support customer
relationship management, customer retention and fraud management applications.
We have designed our solution to provide the carrier-class scalability,
reliability, manageability and flexibility that our customers demand to run
their mission-critical business applications.

     As of June 30, 2000, we had over 50 network service providers customers.
Our customers include BCE Nexxia, Broadwing Communications, Cable & Wireless,
PLC, CPG, Digital Island, Global One Communications, L.L.C., Genuity Inc.,
Harvard University, Mannesman Ipulsys B.V., TV Cabo Acoreana, S.A., UUNET
Technologies Inc, Verio Inc. and WorldCom, Inc. In addition, we have developed
strategic alliances or collaborative relationships with a group of over 85
system integrators, value-added resellers, network infrastructure vendors and
software applications vendors worldwide.

INDUSTRY BACKGROUND

     GROWTH OF INTERNET SERVICES AND DATA TRAFFIC. The Internet is a global
network of interconnected public and private networks that enables millions of
people to communicate, collaborate, access information and conduct business
electronically. International Data Corporation estimates that the number of
worldwide Internet users will grow from 144 million at the end of 1998 to 602
million by 2003. This increased connectivity to the Internet and the
availability of new communications technologies are making Internet-based video,
voice and data communications an integral part of the services offered by
telecommunications carriers, cable network operators, enterprise network
operators, wireless service providers and Internet service providers, which we
refer to collectively as network service providers. The networks of the early
1990s, however, were not designed to handle these new service offerings or the
dramatic increases in data traffic and users. As the variety of service
offerings and the amount of network data traffic have increased, network service
providers have begun to transform their traditional networks into converged,
packet-based networks for integrated voice and data services, or next-generation
networks.

     INCREASING COMPETITION AMONG NETWORK SERVICE PROVIDERS. Increased
acceptance and use of the Internet has forced network service providers to
quickly transition to newer communications technologies to support their new
service offerings. Network service providers seek to differentiate themselves
from their competitors through value-added services such as Internet-based video
and voice transmission, which require rapid and large investments in physical
networks and operations and business support systems. The availability of these
new services to Internet users is causing further acceleration in the growth of
Internet usage and data traffic.

     NETWORK SERVICE PROVIDERS SEEK TO LEVERAGE THE GROWTH OF INTERNET SERVICES
AND DATA TRAFFIC. Network service providers seek to take advantage of the
significant revenue opportunities that have been created by the growing volume
of global Internet traffic and the increasing demand for enhanced Internet-based
communications services. To date, the growth of these opportunities has been
limited by problems associated with Internet access, bandwidth, security and the
quality and range of applications available. As these issues are being
addressed, however, network service providers are finding that their inability
to aggregate and transform raw network usage, traffic and transaction data into
meaningful business information has constrained their revenue generation
potential. Increasingly, network service providers are looking for methods to
move away from flat-fee pricing to business

                                       39
<PAGE>

models based on utility or value to the user and cost to the network service
provider. These new business models will increase revenues by enabling new
services and pricing options, programs to increase customer satisfaction and
differentiation based on quality of service. We believe that the principal
limitation on the ability of network service providers to generate revenues from
the Internet is their lack of a business infrastructure, or Internet
back-office, necessary to support these new business models. This Internet back
office is analogous to the infrastructure that allows traditional
telecommunications companies to manage, measure, monitor and analyze traffic
across telephone networks.

     In order to fully capitalize on the opportunities created by the growth of
the Internet and compete effectively, network service providers need a business
infrastructure that enables the following capabilities:

       o   value-and-utility-based pricing of services and price modeling;

       o   differentiated service levels and quality-of-service metering;

       o   intelligent analysis of real-time network usage data for decision
           support;

       o   customer care/customer relationship management;

       o   fraud prevention and management;

       o   carrier-class scalability, reliability, manageability and
           flexibility;

       o   integration with both next-generation and legacy back-office business
           systems; and

       o   rapid assimilation of new network elements and technologies.

     EXISTING SOLUTIONS ARE LIMITED. Network service providers have attempted to
address these challenges by implementing custom-made, expensive systems tools.
These single-purpose utilities have proven inadequate for multi-service,
multi-vendor and multi-technology global networks. They are typically difficult
to adapt to purposes beyond those for which they originally were constructed and
do not scale to either the types of data traffic or the new technologies,
devices and services that are characteristic of next-generation networks.
Moreover, these solutions rely on separate collection and analysis of network
data, delayed analysis of the data collected and manual service provisioning.
Consequently, current solutions do not provide network service providers with
the Internet back-office functionality needed to create flexible new business
models and manage a dynamic range of customers, service offerings and pricing
structures. This has forced many network service providers to price their
service offerings on a simple, flat-fee basis.

     MARKET OPPORTUNITY FOR A BUSINESS INFRASTRUCTURE THAT EXPANDS REVENUE
GENERATION MODELS. Network service providers can benefit from a new class of
business infrastructure that will allow them to leverage the rapid growth of
Internet services and data traffic into increased opportunities for revenue
generation. We believe that there is significant demand for infrastructure
software that addresses the limitations of existing solutions and enables
network service providers to rapidly capitalize on the growth of the Internet
and to implement higher-margin, enhanced service offerings. This solution must
support high-volume, real-time data collection from multiple sources and all
layers of the network, operate non-intrusively and have sufficiently robust
quality and reliability for the largest carrier-class network service providers.
Network service providers also require a flexible, extensible software platform
that allows them to dynamically monitor, provision and configure multiple
service-types across their networks. Moreover, any solution must readily adapt
to the full range of network devices and standards associated with
next-generation networks. The immediate opportunity for a solution that combines
these attributes is in the market for Internet business infrastructure software,
which The Yankee Group estimates will grow from $207 million in 1999 to $7.7
billion in 2004. We believe, however, that such a solution could also claim a
substantial portion of the larger market for operations support systems, which
The Insight Research Corporation estimates will grow from $33.9 billion in 2000
to $58.4 billion in 2005.

XACCT SOLUTION

     We are a provider of business infrastructure software for the
next-generation public network. Our infrastructure software allows network
service providers to implement new value- and usage-based business models and
offer higher-margin, enhanced services. Network service providers use our
platform to run mission-critical business applications that require
comprehensive real-time data collection, data aggregation and automated service
provisioning. Our solution serves as a software infrastructure for network
service providers that enables the

                                       40
<PAGE>

collection and aggregation of network usage, traffic and transaction data from
network elements such as routers, switches, firewalls, servers and gateways and
the synthesis of that data into the information and formats required by the
billing, customer care, price modeling, customer retention, fraud management,
service level verification and other operations and business support systems of
network service providers. Network service providers can use this real-time data
to offer and charge appropriately for network services based on usage time,
quality of service, transactions, events, content or volume. These network
services include Internet telephony, web hosting, application renting, video
conferencing, movies/video on demand, audio over Internet protocol, unified
messaging, network games, virtual private networking, voice-mail, fax over
internet protocol, e-mail and file transfers. This detailed network information
can also be used to support customer relationship management, customer retention
and fraud management applications. We have designed our solution to provide the
carrier-class scalability, reliability, manageability and flexibility that our
customers demand.

     Our solution offers our customers the following benefits:

     ENABLES INTELLIGENT PRICING OF VALUE-ADDED SERVICES. Our infrastructure
software captures, aggregates and analyzes in real-time the network usage,
traffic and transaction data necessary to allow network service providers to
price their services based on value and utility to the user and cost to the
network service provider. For example, instead of charging a flat-rate fee for
simple Internet access, network service providers can use our solution to offer
and charge appropriately for network services based on criteria such as:

       o   type of application or service being used
       o   type of content
       o   class of service
       o   quality of service
       o   number of transactions
       o   security level
       o   usage time
       o   time of day or time of week
       o   destination and distance
       o   use of internal or external networks

     Our solution also provides detailed network information that can be used to
support customer relationship management, customer retention and fraud
management applications.

     ENABLES AUTOMATED SERVICE PROVISIONING. Our platform is designed to allow
network service providers to implement automated service provisioning, which
allows for automated activation, authentication, authorization and management of
user accounts, as well as self-provisioning, meaning that the network service
provider's users can activate, modify or deactivate services without the
intervention of a network service provider's customer service representative.
Automated service provisioning reduces a network service provider's costs and
time to revenue by streamlining user interactions and increasing user
satisfaction.

     CARRIER-CLASS SCALABILITY AND RELIABILITY. Our software is designed to
support network service providers that operate large and complex networks with
multiple services, also known as carrier-class providers, as well as large
businesses that operate networks within their extended enterprises.
Internet-based services generate significant amounts of data that must be
aggregated, correlated, processed and analyzed in real-time. We have designed
our solution to scale with the growth of our customers' networks and the growth
of network traffic. Our software is designed with a distributed architecture,
meaning that discrete components of the larger software infrastructure are
deployed on or near network elements throughout the network to capture, filter,
aggregate and correlate network usage information from multiple network elements
and all layers of the network. This distributed architecture enables data
filtering and aggregation at the network element level and, by reducing the
volume of data sent over the network, reduces system capacity bottlenecks and
excessive bandwidth use. Our infrastructure solution can therefore scale with
the growth of our customers' networks and network traffic while maintaining data
integrity and high system availability.

     FLEXIBILITY AND EXTENSIBILITY. We have also designed our infrastructure
software as a platform that supports the varying operations and business support
systems employed by different network service providers. We believe our solution
is fully adaptable to all major network infrastructure technologies, including
hardware, software and operations and business support systems. In addition, our
products are designed to work with industry standard

                                       41
<PAGE>

protocols to allow for the rapid and seamless assimilation of new, emerging
network standards, devices and applications. For example, we are currently
extending our platform to incorporate the wireless application protocol, or WAP,
as it continues to develop. Our platform's flexible architecture is designed to
enable our systems to evolve and grow with our customers. As a result, when
network technology providers introduce new hardware or software, we typically
need only four to eight weeks to plan, develop and test a software module to
interface with the new network element.

     MANAGEABILITY. We offer a secure, easy-to-use browser interface through
which network administrators can centrally manage the XACCT business
infrastructure. Our platform enables system-wide and component-specific
upgrades, configuration changes and activation of components. In addition, our
solution offers a wide range of monitoring and built-in reporting capabilities.

STRATEGY

     Our objective is to be the leading provider of business infrastructure
solutions to network service providers. Key elements of our strategy to achieve
this objective include:

     EXTEND PRODUCT AND TECHNOLOGY LEADERSHIP. We created the first commercially
available, carrier-class business infrastructure solution to combine
multi-source, multi-layer data collection and aggregation with automated service
provisioning on a single platform. We will continue to expand our research and
development efforts and enhance our products to expand our market leadership
position as the adoption of next-generation networks continues. In addition, we
intend to continue to introduce new products and services that will enable
network service providers to leverage the rapid growth of Internet services and
data traffic into increased opportunities for revenue generation.

     EXPAND COLLABORATIVE RELATIONSHIPS WITH TECHNOLOGY PROVIDERS. We plan to
leverage our collaborative relationships with key technology providers to
enhance our overall product offerings and better serve our customers. Our
XACCTREADY alliance program, launched in June 1999, now has over 85 members
worldwide, including business applications providers, network hardware and
software vendors and value-added systems integrators. By offering compatibility
with an increasing number of business applications and network hardware and
software platforms, we intend to facilitate broad acceptance of and demand for
our solutions.

     LEVERAGE AND EXPAND STRATEGIC ALLIANCES. We believe that forging strategic
alliances with key systems integrators is critical to delivering comprehensive
business infrastructure solutions. We work closely with major systems
integrators to integrate our solutions into our customers' networks, and we
intend to continue to leverage these relationships to reinforce our position as
the preferred infrastructure platform for next-generation applications
deployment. We also intend to develop additional systems integrator
relationships to increase market penetration and extend the scope of our
customer reach.

     LEVERAGE INSTALLED CUSTOMER BASE. We intend to further penetrate our
existing customers and obtain new customers by capitalizing on the success of
our initial installations and leveraging our ability to deliver scalable,
reliable, carrier-class solutions. The strategic importance of our products to
our customers allows us to develop relationships with our customers' senior
decisionmakers, which in turn facilitates rapid adoption and deployment of our
platform throughout our customers' organizations.

     BROADEN INTERNATIONAL PRESENCE. In addition to our three sales offices in
the United States, we currently maintain direct sales offices in Germany,
Israel, Sweden and the United Kingdom. We plan to expand our direct and indirect
sales channels to include Asia and Latin America, with particular focus on those
areas that are adopting next-generation networks.

PRODUCTS AND TECHNOLOGY

     PRODUCTS

     Our principal product is the XACCTUSAGE software platform. XACCTUSAGE is a
carrier-class software platform that provides two basic functions: network usage
data collection and automated service provisioning. The XACCTUSAGE product
family includes a Service Provider Edition and an Enterprise Edition, each of
which is optimized to meet the special needs of its respective audience.

                                       42
<PAGE>

       The Service Provider Edition is targeted to:

       o   LECS--traditional telecommunications providers, also known as local
           exchange carriers;

       o   CLECS--competitive local exchange carriers;

       o   wireless data service providers;

       o   cable operators that deliver data services;

       o   ISPS--Internet service providers; and

       o   ASPS--applications service providers.

     The Enterprise Edition of XACCTUSAGE is designed for large businesses that
operate networks within the extended enterprise but that do not need the full
range of functionality contained in the Service Provider Edition. Both editions
are based on XACCTUSAGE's core multi-source, multi-layer network usage metering
and multi-service provisioning platform. Both editions are designed to scale to
meet the demands of the largest networks while allowing changes to the network
devices and business applications to be made independently, without disrupting
the operation of business applications or the network.

     TECHNOLOGY

     XACCTUSAGE captures in real-time the Internet protocol session and
transaction information produced and logged by the individual network elements
and, with its real-time enhancement process, transforms this raw data into
meaningful business information. XACCTUSAGE utilizes a variety of
device-specific, as well as general purpose, software agents called information
source modules. These software modules capture, filter, aggregate, correlate and
merge data collected from the various network elements such as routers,
switches, firewalls, authentication servers, lightweight directory access
protocol servers, domain name servers, web servers, email servers, video
servers, voice over IP gateways and hundreds of other network elements. Because
these software modules are located near the network elements, our information
source modules and other modules comprise a distributed software architecture
that allows XACCTUSAGE to capture usage information from all layers of the
network, from the physical layer to the application layer. XACCTUSAGE does not
interfere or disrupt the operation of any network element or service. XACCT
software agents can be activated without adverse impact on network elements,
enabling them to perform multi-service data collection spanning a wide range of
network devices and services.

     DATA COLLECTION AND USAGE. Our platform tracks or meters a variety of
parameters such as actual session quality of service, bandwidth used, bit-rate,
duration and applications launched by the end-user, and transforms this data
into a clear and detailed picture of user-level service utilization. We refer to
this output as extensible detail records. Extensible detail records are
comprehensive and extensible usage records that are roughly analogous to the
telephone communications industry's call detail records. Unlike call detail
records, however, extensible detail records can be configured to virtually any
data format and transport and can therefore be readily integrated with the
existing operations support and business support systems of network service
providers. Thus, extensible detail records also allow network service providers
to use this data for a variety of business planning and decision support
purposes such as:

       o   usage-based pricing for network services;

       o   user and application profiling;

       o   service usage audits;

       o   capacity planning; and

       o   other traffic engineering purposes.

     SERVICE PROVISIONING. The automated, end-to-end service provisioning
capabilities of the XACCTUSAGE platform enable network service providers to
implement real-time subscriber activation, authentication, authorization and
management. Instead of manually configuring services for an existing or a new
subscriber, the network service providers' customer service application passes
the information to XACCTUSAGE via its application programming interface. The
XACCT service provisioning modules, in turn, configure the relevant application
servers automatically in real-time and notify the network service provider's
customer service representative upon completion. In the case of bundled
services, if while configuring multiple services the system encounters a problem

                                       43
<PAGE>

with a specific service, the XACCT system has the intelligence to roll back the
entire operation upon identifying a specific problem and alert the network
service provider so that corrective actions can be promptly taken.

     In addition, network service providers can offer customer self-care
programs that allow the customers to add, delete and modify their services and
service plans, in real-time, without using the network service provider's call
center. This feature allows network service providers to reduce their call
center costs, improve customer satisfaction and shorten their time to revenue.

     PRODUCT ARCHITECTURE

     The XACCT architecture is composed of several well-defined functional
layers, which together provide for the scalability, flexibility, availability
and manageability of our platform.

     [Diagram of the architecture of XACCTUSAGE: information source modules and
service provisioning modules connect various network elements represented at the
bottom of the diagram (a Lightweight Directory Access Protocol server, RADIUS
accounting server, mail server, router, switch, voice over IP gateway, web
server and application server) to various gatherers and aggregators; the
gatherers and aggregators are connected to the central event manager portion of
the core system; the core system is connected through a user interface server to
billing, customer care, price modeling, customer retention, fraud management,
service level verification and other operations and business support systems of
network service providers represented at the top of the diagram; the core system
is also connected through a user interface server to an XACCT user interface
represented at the right side of the diagram; the core system is also connected
to a central database represented at the left side of the diagram.]

     CENTRAL EVENT MANAGER. The central event manager is a server component that
provides centralized management and control of all XACCT components. The central
event manager orchestrates and controls the distribution, deployment and
configuration of the various modules, as well as communication among information
source modules, for the purpose of data collection, provisioning and data
storage in the central database.

     USER INTERFACE SERVER. The user interface server is a server component that
provides a single, secure point of contact for administration and system
management purposes. The user interface server can be accessed through a
standard, off-the-shelf web-browser without the need for any prior client
software installation, allowing for secure access to the system locally or
remotely. The user interface server enables efficient, centralized system
administration to facilitate system reconfigurations and field upgrades. The
user interface server also includes a customized reporting system with built-in
report generation capabilities. The user interface server can also accommodate
the use of third party reporting packages.

     XACCT INTERFACE SERVER. The XACCT interface server, or the XIS, is an
add-on to XACCTUSAGE that serves as a gateway to the system and enables direct
integration with external systems, such as the operations and business support
systems of network service providers. The XIS can be configured to produce
specified data formats and transport methods required by the operations and
business support service applications of network service providers, as well as
to facilitate the integration of XACCTUSAGE with those applications. Network
service providers can use the XIS to send the network usage, traffic and
transaction data that XACCTUSAGE collects directly into their operations and
business support systems. Network service providers can also use the XIS to
develop custom client applications that link the XIS with their back-office
applications to perform service provisioning. XIS's built-in, real-time
provisioning transaction server enables automated flow-through provisioning of
simple or compound services.

     GATHERERS. Gatherers perform flexible, policy-based data filtering and
aggregation of network usage, traffic and transaction data. Gatherers can
perform multiple tasks at the same time using policy-based processing. Gatherers
are software agents that run as background processes on dedicated or
non-dedicated hosts. Gatherers can be installed on the same network segment as
the source device such as a router and switch or on the application server
itself to minimize the data traffic impact on the network. This localized data
filtering and aggregation improves the scalability and efficiency of the system
by reducing the volume of data sent over the network to the central event
manager, providing only necessary information and avoiding duplication.
Gatherers can host multiple information source modules.

     INFORMATION SOURCE MODULES. Information source modules are highly
configurable, distributed, add-on modules that act as interfaces, or
translators, that send Internet protocol session data in real-time from network

                                       44
<PAGE>

elements to gatherers. Information source modules are modular, abstract
interfaces that are designed to be platform neutral to facilitate integration of
the XACCTUSAGE infrastructure with an existing network. Each information source
module is designed for a specific type of network data source. The following are
categories of information source modules:

       o   DATA COLLECTION MODULES are modules used to extract and collect
           information from various network and service elements, including
           transport devices and application level systems. Data collection
           modules can be single-purpose, vendor-specific modules or
           general-purpose, standards-based modules.

       o   DATA ENHANCEMENT MODULES are modules used to synthesize, through
           general-purpose functions and mathematical calculations, data
           acquired from multiple sources to create records that contain the
           information that meet the specific requirements of network service
           providers.

       o   DATA PROCESSING MODULES are modules used to process collected data,
           including data processed by other data processing modules, and to
           perform logical operations like data aggregation, filtering and
           merging.

     Information source modules are packaged separately, allowing network
service providers to customize information source module configurations to meet
the specific requirements of their networks. The XACCTUSAGE infrastructure is
designed to permit dynamic reconfiguration in which modules may be upgraded,
added or removed without disrupting ongoing operation.

     SERVICE PROVISIONING MODULES. Service provision modules are highly
configurable, distributed modules designed to enable service provisioning
information to flow into various network elements to add, remove and update user
account information.

     CENTRAL DATABASE. The central database is a central repository of both
system-wide configuration information and collected network usage, traffic and
transaction data. Network usage, traffic and transaction data can be fed
directly to the operations and business support systems of the network service
providers or stored in the database. Network service providers can use this data
repository for off-line mining and analysis of collected data. Network service
providers can modify the database structure to suit their needs. While
XACCTUSAGE does not itself contain a database management system, XACCTUSAGE is
available bundled with third party database management systems.

     PRODUCT FEATURES

     NON-INTRUSIVE NETWORK INTERFACES FOR COLLECTION AND PROVISIONING.
XACCTUSAGE's non-intrusive operation does not interfere or disrupt the operation
of any network elements or services. XACCT software agents can be activated
without any adverse impact on network elements, enabling them to perform
multi-service data collection spanning a wide range of network devices and
services from the physical layer to the application layer.

     MODULAR, DISTRIBUTED DATA PROCESSING CAPABILITIES. The XACCTUSAGE
architecture is designed to work in distributed heterogeneous environments and
is capable of running on multiple platforms. The modular, distributed design
also enables at-source data filtering and aggregation to reduce system capacity
bottlenecks and excessive bandwidth utilization caused by the collection
process. The real-time, policy-based filtering, aggregation, enhancement and
merging capabilities enable XACCTUSAGE to scale and adapt to the large and
complex networks of our customers.

     OPEN, EXTENSIBLE DATA OUTPUT AND PROVISIONING INTERFACES. The XACCT
Interface Server can be configured to produce specified data formats and
transport methods to match downstream applications, as well as to allow for
quick and easy integration with back-office applications. XACCT Interface
Server's real-time provisioning transaction server enables automated
provisioning of complex services.

     UNIFIED, SECURED, WEB-BASED MANAGEMENT. Our web-based user interface allows
secure access to the system with off-the-shelf browsers, locally or remotely.
Our user interface server allows for efficient, centralized system
administration to allow easy system reconfigurations and field upgrades. Our
user interface server also includes a customizable reporting system with
built-in report generation. An open database connectivity compliant interface is
also available to enable the use of off-the-shelf graphical reporting packages.

     LICENSING ARRANGEMENTS

     We license XACCTUSAGE and the XACCT Interface Server pursuant to
non-exclusive and non-transferable end-user license agreements. The end-user
license agreements impose restrictions on the customers' ability to use

                                       45
<PAGE>

the software other than for purposes that we have agreed with the customer and
typically refer to an agreed-upon network architecture.

     Support obligations are typically covered by an additional support
agreement or by a support exhibit to our agreements with customers. Our supports
agreements and exhibits typically require annual payments by the customer for
support, product releases and upgrade services.

CUSTOMERS AND CASE STUDIES

     We have initially targeted network service providers and integrated
communications providers such as local exchange carriers, competitive local
exchange carriers, cable operators, wireless operators, Internet service
providers and application service providers. As of June 30, 2000, over 50
customers had licensed XACCTUSAGE, including the following:

        BCE Nexxia Inc.                          Harvard University
        Broadwing Communications                 Mannesman Ipulsys B.V.
        Cable & Wireless, PLC                    TV Cabo Acoreana, S.A.
        CPG                                      UUNET Technologies, Inc.
        Digital Island                           Verio Inc.
        Global One Communications, L.L.C.        WorldCom, Inc.
        Genuity Inc.

     In 1999, a small number of customers accounted for a significant portion of
our total revenues. During that year, revenues from four customers accounted for
51% of total revenues. We expect that revenues from a limited number of
customers will continue to account for a large percentage of total revenues in
future quarters. TV Cabo, UUNET Technologies, Inc., Genuity Inc. and Verio Inc.
each accounted for at least 10% of total revenues in 1999. Sales to Digital
Island, CPG, Cable & Wireless, PLC and WorldCom, Inc. accounted for 51% of our
revenues in the first two quarters of 2000. In the first two quarters of 2000,
Digital Island, Cable & Wireless, PLC, CPG and WorldCom, Inc. each accounted for
at least 10% of total revenues.

     In 1999, we derived 63% of our revenues from customers located in North
America and 37% from customers outside North America, substantially all of which
were in Europe. Please see note 9 to our consolidated financial statements for
additional financial information presented by geographic area.

     In 2000, we derived 67% of our revenue from customers in North America and
33% of our revenue from customers outside of North America.

     The following case studies illustrate how some of our customers are using
XACCTUSAGE:

     BROADWING

     Broadwing Communications is a wholly-owned subsidiary of Broadwing Inc.
Broadwing Inc. is an integrated communications company that delivers voice, data
and Internet solutions to a variety of customers nationwide.

             CHALLENGE:  Broadwing needed to build a flexible business
       infrastructure that could support the rapid deployment of new network
       services differentiated by value-based pricing.

             SOLUTION: We designed and implemented a solution for Broadwing that
       normalizes data collected from multiple network elements in order to
       measure customer bandwidth utilization. The ability of XACCTUSAGE to
       selectively filter and aggregate incoming data allows the system to
       handle large volumes of incoming data with minimal network impact.
       Real-time correlation of this data with Broadwing's operational databases
       allows Broadwing to measure the bandwidth delivered for each type of
       service on a per customer basis. A key benefit of the adoption of
       XACCTUSAGE is the granular view into network management traffic data now
       available to Broadwing. Further the seamless integration of XACCTUSAGE
       with Broadwing's existing Kenan billing system enables Broadwing to offer
       new services quickly and with minimal disruption.

                                       46

     GLOBALONE

     GlobalOne is a worldwide provider of voice, data and Internet Protocol, or
IP, network services. GlobalOne is a subsidiary of France Telecom.

             CHALLENGE: GlobalOne needed to deploy a single, scalable and
       flexible platform that would provide it with bandwidth utilization and
       service management metrics on a per customer basis and that would enable
       it to offer differentiated, usage-based, bandwidth-on-demand services.

             SOLUTION: XACCTUSAGE captures, aggregates and consolidates all IP
       traffic data from GlobalOne's worldwide network of Cisco routers in
       real-time and correlates this data with customer information in
       GlobalOne's operational database, enabling it to support customer service
       level agreements. XACCTUSAGE also extracts information on network
       performance and data transmission burst rates. The XACCTUSAGE system
       correlates information in multiple formats into a single, normalized
       billing record that incorporates bandwidth utilization, network
       performance and service level metrics. The resulting record is presented
       in formats that can be processed by any of the several billing systems in
       use at GlobalOne. Our solution allows GlobalOne to provide data in
       support of service level agreements, and to offer differentiated,
       usage-based pricing models that allow it to offer bandwidth-on-demand
       service.

COLLABORATIVE RELATIONSHIPS AND STRATEGIC ALLIANCES

     To enhance the productivity of our sales and service organizations, we have
established relationships with system integrators, value-added resellers,
network infrastructure vendors and software applications vendors through our
XACCTREADY program.

     SYSTEM INTEGRATORS AND VALUE-ADDED RESELLERS. We have established strategic
relationships with a number of leading system integrators. Many of our system
integrators have established relationships across a broad range of network
service providers and enterprise customers and our relationships with these
system integrators often enable us to reach key decision-makers within these
enterprises more quickly, thus reducing sales cycles. Working with system
integrators enables us to leverage their professional services and integration
resources and shorten solution implementation time. In addition, by leveraging
our partners' domain expertise, we can more effectively and rapidly penetrate
vertical markets. We also market XACCTUSAGE through value-added resellers.
Value-added resellers enable us to seed the market with specific pre-packaged
solutions built on the XACCTUSAGE platform. Many of these value-added resellers
specialize in providing solutions to particular market segments, including the
network service provider, government and large enterprise segments. We intend to
leverage the domain expertise of our value-added resellers to deliver solutions
that accelerate our penetration in key markets.

     We had relationships with the following system integrators and value-added
resellers as of June 30, 2000:

SALES AND MARKETING

     We license our products and sell services primarily through our direct
sales organization, complemented by the selling and support efforts of our
authorized value-added resellers, including system integrators, and other
strategic partners. As of June 30, 2000, our sales force consisted of 27 sales
professionals and 24 technical field professionals. We have sales offices in or
near the greater metropolitan areas of Atlanta, Denver, San Francisco,
Ramat-Gan, Israel, London, England, Stockholm, Sweden and Berlin, Germany.
System engineers who provide pre-sales support to potential customers on product
information and deployment capabilities complement our direct sales
professionals. We plan to significantly expand the size of our direct sales
organization and to establish additional sales offices domestically and
internationally.

     Our sales process requires that we work closely with targeted customers to
identify short-term technical needs and long-term goals. Our sales team, which
includes both sales and technical professionals, then works with the customer to
develop a proposal to address these needs. In many cases, we collaborate with
our customers' senior management to develop mission-critical applications. The
level of customer analysis and financial commitment required for many of our
product implementations has caused our sales cycle generally to range from three
to nine months.

     We focus our marketing efforts on educating potential customers, generating
new sales opportunities, and creating awareness of our product and their
applications. We conduct a variety of marketing programs to educate our target
market, including seminars, trade shows, direct mail campaigns, press relations
and industry analyst programs.

SERVICE AND SUPPORT

     The primary function of our professional services organization is to
facilitate the implementation of our product by customers and system
integrators. We provide services directly to our customers and to system
integrators for XACCTUSAGE project planning, implementation and performance. Our
professional services organization works closely with system integrators to
train their personnel in the design and implementation of our product line.

     We offer different customer support options to our customers, ranging from
local business hour support to seven days a week, 24 hours-a-day support with a
dedicated customer support representative.

     Our professional services and customer support groups deliver education and
product training to our customers and strategic partners relating to the design
of business solutions using XACCTUSAGE, as well as the technical aspects of
deployment, use and maintenance. Our professional service and customer support
organizations consisted of 36 employees as of June 30, 2000.

                                       48
<PAGE>

RESEARCH AND DEVELOPMENT

     As of June 30, 2000, our technical and engineering staff consisted of 71
employees who research and develop advanced architecture and technologies as
well as back-office applications, create technological documentation for
products and provide quality assurance throughout the development cycle.

     Since our inception, we have focused our research and development efforts
on developing and enhancing XACCTUSAGE. We are currently working to increase the
performance, quality, features, coverage and manageability of our XACCTUSAGE
product and to develop back-office applications. Research and development
expenses were $390,000 in the period from our inception in June 1997 through
December 31, 1997, $1.5 million in 1998, $2.2 million in 1999 and $4.0 million
for the six months ended June 30, 2000.

COMPETITION

     The market for our product is new, evolving and subject to rapid
technological change. To date, our primary competition has come from solutions
developed by the in-house technology departments of potential customers or
partners. We have experienced and expect to continue to experience increased
competition from current and potential competitors. Many of these companies have
greater name recognition, longer operating histories, larger customer bases and
significantly greater financial, technical, marketing, public relations, sales,
distribution and other resources. Some of our potential competitors are among
the largest and most well capitalized software, hardware and communications
companies in the world. Our competitors include:

     o    in-house information technology departments of potential customers or
          partners that have developed or may develop systems that substitute
          for some or all of the functionality of our XACCTUSAGE product;

     o    companies with products that address our market, such as Hewlett
          Packard Co., Lucent Technologies Inc., EHPT Sweden AB and Narus, Inc.;
          and

     o    companies that have developed software that addresses only certain
          components of Internet Protocol mediation.

     We are also aware of numerous other companies that are focusing significant
resources on developing and marketing products that will compete with
XACCTUSAGE. Additional competitors could come from a number of companies that
produce application integration or communication software.

     We expect that competition will increase in the near-term and that our
primary long-term competitors may not have entered the market yet. If any of our
competitors were to become the industry standard or were to enter into or expand
relationships with significantly larger companies through mergers, acquisitions
or otherwise, our business and operating results could be significantly harmed.
In addition, potential competitors may bundle their products or incorporate
functionality into existing products in a manner that discourages users from
purchasing our products. Increased competition could result in price reductions,
fewer customer orders, reduced gross margin and loss of market share, any of
which could cause our business to suffer.

     We believe that the principal competitive factors in our market include:

     o    product quality, scalability, performance and reliability;

     o    the ability of products to operate with multiple software
          applications;

     o    the ability of products to operate with multi-vendor network
          infrastructure products, hardware and software platforms;

     o    establishment of a significant base of reference customers;

     o    ability to implement solutions quickly;

     o    customer service;

     o    relationship with system integrators and value-added resellers;

     o    strength of core technology; and

     o    product price.

                                       49
<PAGE>


     Although we believe that we compete favorably with respect to these
factors, our market is relatively new and is evolving rapidly. We may not
compete successfully against current and potential competitors.

INTELLECTUAL PROPERTY AND OTHER PROPERTY RIGHTS

     Our success is dependent upon our ability to develop and protect our
proprietary technology and intellectual proprietary rights. To protect our
proprietary technology and intellectual property, we rely primarily on a
combination of contractual provisions, confidentiality procedures, trade
secrets, and copyright and trademark laws. However, we believe that factors such
as the technological and creative skills of personnel, new product developments,
frequent product enhancements and reliable product maintenance are more
essential to establishing and maintaining a technology leadership position. We
cannot assure you that others will not develop technologies that are similar or
superior to our technology.

     We license XACCTUSAGE pursuant to non-exclusive end-user license agreements
that impose restrictions on our customers' ability to utilize the software. In
addition, we seek to avoid disclosure of our trade secrets, including but not
limited to, requiring employees, customers and others with access to our
proprietary information to execute confidentiality agreements with us and
restricting access to our source code. We also seek to protect our software,
documentation and other written materials under trade secret and copyright laws.

     Our license agreements generally provide that licensees will have a
limited, non-exclusive right to use this code if:

     o    there is a bankruptcy, insolvency or winding-up proceeding involving
          us;

     o    we cease to do business without a successor; or

     o    we do not provide contractually agreed maintenance and support.

     Some of our license agreements also require us to place the source code for
XACCTUSAGE into escrow.

     We have two U.S. patent applications pending. It is possible that the
patents that we have applied for, if issued, or our potential future patents may
be successfully challenged or that no patent will be issued from our patent
application. It is also possible that we may not develop proprietary products or
technologies that are patentable, that any patent issued to us may not provide
us with any competitive advantages, or that the patents of others will seriously
harm our ability to do business.

     We have received an initial refusal of our application to register our
XACCT trademark in the United States. We are currently preparing a response to
the United States trademark office. If we receive a final rejection of our
application to register the XACCT trademark, we will likely experience greater
expense and difficulty in protecting the XACCT mark and its derivatives.

EMPLOYEES

     As of June 30, 2000, we had a total of 204 full time employees. Of the
total number of employees, 71 were engaged in research and development, 51 in
sales, 15 in marketing, 36 in customer support, professional services and
training, and 31 in administration and finance. None of our employees are bound
by an employment agreement requiring service for any defined period of time.
None of our employees are represented by a labor union. We have not experienced
any work stoppage and consider our relations with our employees to be good.

     As of June 30, 2000, 85 of our employees were located in Israel. We are not
a party to any collective bargaining agreement with our employees. However,
Israeli law and certain provisions of the nationwide collective bargaining
agreements between the government of Israel, the Histadrut, which is the General
Federation of Labor in Israel, and the Coordinating Bureau of Economic
Organizations which is the Israeli federation of employers' organizations, apply
to our Israeli employees by way of expansion orders of the Israeli Ministry of
Labor and Welfare. These provisions and other mandatory provisions of Israel law
principally concern the maximum length of the work day and the work week,
minimum wages, contributions to a pension fund, insurance for work-related
accidents, procedures for dismissing employees, determination of severance
payment and other conditions of employment. Furthermore, pursuant to such
provisions, the wages of most of our employees are subject to increase as a
result of cost of living adjustments, based on changes in the Israeli Consumer
Price Index. The formulas for those adjustments and their amounts and frequency
are modified from time to time according to the agreements reached between the
government of Israel, the Manufacturers Association and the General Federation
of Labor in Israel. Israeli law generally requires the payment of severance pay
upon the retirement or death of an employee or upon termination of employment by
the employer or, in certain circumstances, by the employee. We currently fund

                                       50

most of our ongoing severance obligations for our Israeli employees by making
monthly payments for insurance policies to cover these obligations.

BOARD OF DIRECTORS

       Immediately following this offering, our board of directors will consist
of 7 directors. As set forth in our articles of association, the person serving
as our Chief Executive Officer will be appointed automatically to the board,
subject to annual shareholder approval. The remaining six directors will be
divided into three classes with each class serving an initial term ranging from
less than one year to three years and thereafter for additional three year
terms. Upon completion of this offering, we will be required under Israeli law
to have two outside or independent directors who will serve a three year term
that can be extended for one additional three year term. The first outside
directors shall be appointed by a general meeting convened not later than three
months after the date on which we become a public company.

       At each annual general meetings of shareholders, the directors who are up
for election to succeed those directors who resign or whose terms are expiring
will be elected by the holders representing the requisite majority of our
ordinary shares as may be required by law. In addition, our articles of
association provide that our authorized number of directors may be changed by
modifying the articles of association by an affirmative vote of 75% of those


                                       53
<PAGE>

present and voting at a general meeting of shareholders. This classification of
the board of directors may have the effect of delaying or preventing changes in
the effective control of our company.

       ALTERNATIVE DIRECTOR

       Our articles of association allow a director to appoint an alternative
director possessing all the rights and obligations of the director who appointed
him or her, except that the alternate has no standing at any meeting while the
appointing director is present and is not entitled to remuneration. A person who
is not qualified to be appointed as a director, or a person who already serves
as a director or an alternative director, may not be appointed as an alternative
director. Unless the appointing director limits the time or scope of the
appointment, the appointment is effective for all purposes until the appointing
director ceases to be a director or terminates the appointment. The appointment
of an alternative director does not in itself diminish the directorship
responsibilities of the appointing director.

       OUTSIDE OR INDEPENDENT DIRECTORS

       Under the new Israeli Companies Law, 1999-5759, or the Companies Law,
effective as of February 1, 2000, companies incorporated under the laws of the
State of Israel whose shares have been offered to the public in or outside of
Israel are required to appoint at least two outside or independent directors.
The Companies Law provides that a person may not be appointed as an outside
director if such person or such person's relative, partner, employer or any
entity under such person's control, has, as of the date of such person's
appointment as an outside director, or had, during the two years preceding that
date, any affiliation with the company or any entity controlling, controlled by
or under common control with the company. The term "affiliation" includes:

       o  an employment relationship;

       o  a business or professional relationship maintained on a regular basis;

       o  control; and

       o  service as an office holder.

       The Companies Law requires that the outside directors be residents of
Israel. However, the Minister of Justice of the State of Israel has promulgated
regulations exempting certain qualifying foreign companies such as our company
from the applicability of certain provisions of the Companies Law. A "foreign
company" is defined in The Companies Regulations (Concessions for Public
Companies Whose Shares are Registered in a Stock Exchange Outside Israel),
5760-2000, or the regulations, as a public company whose shares were offered to
the public solely outside of Israel or are registered only on a stock exchange
outside of Israel. Pursuant to the regulations, the outside directors of the
foreign company need not be an Israeli resident. No person may serve as an
outside director if such person's position or other business activities create,
or may create, a conflict of interest with the person's responsibilities as an
outside director, or may otherwise interfere with the person's ability to serve
as an outside director. If at the time of the appointment of the outside
directors our board shall be comprised of members of only one gender, then at
least one of the outside directors must be of the other gender.

       Outside directors are to be elected by a majority vote at a shareholders'
meeting, provided that either:

       o  the majority of shares voted at the meeting, including at least
          one-third of the shares of non-controlling shareholders voted at the
          meeting, vote in favor of election of the outside director; or

       o  the total number of shares of non-controlling shareholders voted
          against the election of the outside director does not exceed 1% of
          the aggregate voting rights in the company.

       The initial term of an Israeli outside director is three years and it may
be extended for one additional three year term. Each committee of a company's
board of directors is required to include at least one outside director, except
for the audit committee which must include both outside directors, as also
required by the Nasdaq National Market. We intend to take all actions necessary
to comply with the Companies Law and its requirements relating to the
appointment of outside directors upon the completion of this offering.

       An outside director is entitled to compensation as provided in the
regulations that have been adopted pursuant to the Companies Law, and the
outside director is otherwise prohibited from receiving any other compensation,
directly or indirectly, in connection with his or her services as an outside
director.

       BOARD COMMITTEES

       COMPENSATION COMMITTEE. The board of directors has a compensation
committee that was established in November 1998. The compensation committee,
currently comprised of Messrs. Hawk, Springer and Yanovski, makes
recommendations with respect to share option plans and share purchase plans, and
all matters concerning executive compensation and employee agreements.

       AUDIT COMMITTEE. The Companies Law requires public companies to appoint
an audit committee. The responsibilities of the audit committee under the
Companies Law include identifying irregularities in the management of the
company's business and approving related party transactions as required by
Israeli law. Under the Companies Law, an audit committee must consist of at
least three directors, including two outside directors. The chairman of the
board of directors, any director employed by or otherwise providing services to
the company, and any controlling shareholder or any relative of a controlling
shareholder, may not be a member of the audit committee. In addition, pursuant
to the listing requirements of the Nasdaq National Market, we will be required
to have at least two independent directors on our audit committee. Our audit
committee was formed in November 1998 and is currently comprised of Messrs.
Reynolds, Springer and Yanovski. Our audit committee performs the following
functions:

        o     monitors our system of internal controls;

        o     monitors corporate financial reporting and internal and external
              audits;

        o     provides the board of directors with the results of its
              examinations and recommendations;

        o     outlines to the board of directors the improvements made or to be
              made in internal accounting controls;

        o     nominates independent auditors; and

        o     provides the board of directors with other financial information
              and materials necessary to make the board of directors aware of
              significant financial matters.

       We intend to appoint an audit committee which complies with the
requirements of the Companies Law upon completion of this offering and following
the appointment of outside directors as provided above.

       INTERNAL AUDITOR

       Under the Companies Law, public companies must appoint an internal
auditor that will be appointed by the board of directors following
recommendation by the audit committee. The role of the internal auditor is to
examine, among other matters, whether the company's actions comply with the law
and orderly business procedure. Under the Companies Law, the internal auditor
may be an employee of the company but not an interested party, an office holder,
an affiliate or a relative of an interested party, office holder or affiliate,
and he or she may not be the company's independent accountant or its
representative. We intend to appoint an internal auditor in accordance with the
requirements of the Companies Law upon the completion of this offering.

       DIRECTOR COMPENSATION

       We do not currently pay cash compensation to our directors in their
capacity as directors, except for reimbursement of business, travel and other
related expenses. As described below in "Related Party Transactions," we have
granted options to Robert Hawk.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

       The compensation committee is currently comprised of Messrs. Hawk,
Springer and Yanovski. Messrs. Hawk, Springer and Yanovski have served on the
compensation committee since their appointment in November 1998. None of these
committee members has at any time been an officer or employee of our company or
of our subsidiaries. You should note the following relationships and
transactions with members of the compensation committee and their affiliates:

       ROBERT C. HAWK. In July 1998, Mr. Hawk purchased 63,455 ordinary shares
at $0.19 per share pursuant to a restricted stock purchase agreement. Under the
restricted stock purchase agreement, Eran Wagner and Limor Schweitzer have the
right to repurchase those ordinary shares. The right of Eran Wagner and Limor
Schweitzer to


                                       55
<PAGE>

repurchase those ordinary shares lapsed as to one-fourth of the total number of
shares on the first anniversary of the grant date and lapses as to 1/12th of the
total shares each quarter thereafter. The lapsing of the repurchase right is
dependent upon the continued service by Mr. Hawk on our board of directors. In
May 1999, Mr. Hawk received an option to purchase 24,500 ordinary shares at an
exercise price of $0.35 per share. Mr. Hawk purchased 24,500 ordinary shares

OPTION GRANTS IN LAST FISCAL YEAR

       The following table sets forth information with respect to share options
granted to our Chief Executive Officer and our other most highly compensated
executive officers during the fiscal year ended December 31, 1999. We have never
granted any share appreciation rights. All option grants listed in the table
below were made under our 1998 Stock Option Plan, the 1998 Section 102 Share
Option Plan or Section 3(i) of the Israeli Income Tax Ordinance. Percentage of
total options is based on an aggregate of 1,437,170 ordinary shares granted
under the 1998 Stock Option Plan, the 1998 Section 102 Share Option Plan or
Section 3(i) of the Israeli Income Tax Ordinance in the year ended December 31,
1999. The 5% and 10% assumed annual rates of share price appreciation are
required by the rules of the Securities and Exchange Commission and do not
represent our estimate or projection of future ordinary share prices. The
potential realizable values at 5% and 10% appreciation are calculated by
assuming that the estimated fair market value on the date of grant is equal to
an assumed initial public offering price of $10.00 per share and appreciates at
the indicated rate for the entire term of the option and that the option is
exercised at the exercise price and sold on the last day of its term at the
appreciated price.

     OTHER AGREEMENTS

     We require each of our employees to enter into proprietary rights and
invention assignment agreements prohibiting the employee from disclosing any of
our confidential or proprietary information. In addition, the agreements
generally provide that upon termination the employee will not solicit our
employees for a period of 12 months. Substantially all of our key employees in
Israel have agreed not to compete with us for one year following the termination
of their employment with us. A recent decision of the Supreme Court of the State
of Israel has severely restricted the enforceability of non-competition clauses
for Israeli employees. At the time of commencement of employment, our U.S.
employees also generally sign offer letters specifying certain basic terms and
conditions of employment and our Israel employees generally sign employment
agreements specifying certain basic terms and conditions of employment,
including customary notice provisions for termination consistent with Israeli
law.

EMPLOYEE BENEFIT PLANS

     SECTION 102 SHARE OPTION PLAN

     In July 1998, our board of directors adopted the Section 102 Share Option
Plan in accordance with Section 102 of the Israeli Income Tax Ordinance. The
Section 102 Share Option Plan expires in 2006. As of June 30, 2000, we had
outstanding options to purchase 839,802 ordinary shares under the plan at a
weighted average exercise price of $0.87 per ordinary share. As of that date,
our officers held options to purchase 192,724 ordinary shares under the Section
102 Share Option Plan, and no director held any options issued under the plan.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE SECTION 102 SHARE OPTION
PLAN. Under the Section 102 Share Option Plan, we have reserved an aggregate of
2,060,000 ordinary shares for grant to our Israeli employees.

     EXERCISE PRICE AND FORM OF OPTIONS. Our board of directors determines the
exercise prices of options granted under the Section 102 Share Option Plan at
the time of the grant. The options granted under the plan typically expire no
later than eight years from the date of grant. Any shares subject to options
that are cancelled or not exercised before expiration become available for
future grant.

     ADMINISTRATION OF SECTION 102 SHARE OPTION PLAN. In general, our board of
directors administers the Section 102 Share Option Plan. Our board of directors
determines the terms of the options granted, including the exercise price, the
number of ordinary shares subject to each option, the exercisability of the
options and the form of consideration payable upon exercise.

     RIGHTS UPON TERMINATION. Pursuant to the Section 102 Share Option Plan, if
the employment of any optionee is terminated as a result of death or disability
of such optionee, the optionee or his or her heirs may, within a period of three
months following the termination, exercise the options that were already vested
upon such termination.

     TRANSFERABILITY OF OPTIONS. Except for transfer as a result of death, the
Section 102 Share Option Plan does not allow for the transfer of options and
only the optionee may exercise an option.

     ADJUSTMENTS UPON MERGER. The Section 102 Share Option Plan provides that in
the event of a merger with or into another corporation, the successor
corporation shall assume or substitute equivalent options for each option.
However, in the event that the successor corporation will not agree to assume
the options, then all outstanding options will accelerate and become fully
vested ten days prior to the close of the merger.

     PROXY. Until we become a public company, any shares purchased through the
exercise of an option granted under the Section 102 Share Option Plan are voted
by proxy pursuant to the directions of our board of directors, with the proxy to
be given to the person or persons designated by our board of directors.
Currently, Eran Wagner and Limor Schweitzer are the persons designated by our
board of directors to vote the proxies.

     TAXATION. Pursuant to Section 102 of the Israeli Income Tax Ordinance and
the rules promulgated thereunder (including the requirement that the options and
the underlying shares be deposited with a trustee for a period of at least two
years), the tax on the benefit arising to the employee from the grant and
exercise of options as well as from the allotment of ordinary shares under these
options is deferred until the transfer of the options and ordinary shares to the
employee's name or upon the sale of those options and/or ordinary shares. We
will be allowed to claim as an expense for tax purposes the amounts credited to
the employees as a benefit upon sale of the shares allotted under the plan. The
benefit is equal to the difference between the market price and the exercise
price. The related capital gains tax is payable by the employee.

     SECTION 3(I) SHARE OPTION PLAN

     Section 3(i) of the Israeli Income Tax Ordinance governs the tax treatment
of share options not issued pursuant to Section 102 of the Israeli Income Tax
Ordinance. As of June 30, 2000, we had outstanding an aggregate of 741,718
options, at a weighted average exercise price of $3.45 per share, that will be
taxed in accordance with Section 3(i) of the Israeli Income Tax Ordinance. In
April 2000, our board of directors adopted the Section 3(i) Share Option Plan.
The Section 3(i) Share Option Plan will be effective for a period of ten years
commencing upon the date of its adoption. As of June 30, 2000, no options have
been granted under this plan.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE SECTION 3(I) SHARE OPTION
PLAN. As of June 30, 2000, a total of 700,000 of our ordinary shares have been
reserved for issuance under the Section 3(i) Share Option Plan. Any shares
subject to options that are cancelled or not exercised before expiration will
become available for future grant.

     ADMINISTRATION OF SECTION 3(I) SHARE OPTION PLAN. In general, our board of
directors administers the Section 3(i) Share Option Plan. Our board of directors
determines the terms and conditions of the options, as well as the identity of
the participants and the number of ordinary shares covered by each option
granted under the Section 3(i) Share Option Plan, based upon a recommendation of
the compensation committee.

     RIGHTS UPON TERMINATION. The Section 3(i) Share Option Plan provides that
in case the employment of any optionee is terminated as a result of death or
disability of such optionee, the optionee or his or her heirs may, within a
period of three months following the termination, exercise the options that were
already vested upon the time of the termination. This period may be extended by
our board of directors for a period not to exceed the period during which the
options by their terms would otherwise have been exercisable.

     TRANSFERABILITY. Except for transfer as a result of death, the Section 3(i)
Share Option Plan does not allow for the transfer of options and only the
optionee is allowed to exercise an option.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. The Section 3(i) Share Option Plan
provides that in the event of a merger with or into another corporation or a
sale of all or substantially all of our assets, the successor corporation shall
assume or substitute equivalent options for each outstanding option. However, in
the event that the successor corporation will not agree to assume or substitute
the options, then all outstanding options will accelerate and become fully
vested ten days prior to the close of the merger or sale.

     TAXATION. The options and the underlying shares are exercisable or
available for sale immediately upon vesting and are not required to be deposited
in trust. The participants in the Section 3(i) Share Option Plan are not
eligible for any tax benefits or deferrals. We are allowed to claim as an
expense for tax purposes the amounts credited to the employees as a benefit upon
sale of the shares allotted under the plan. The related income tax or capital
gain tax are paid by the participants.

     1998 STOCK OPTION PLAN

     Our board of directors adopted the 1998 Stock Option Plan in July 1998. Our
1998 Stock Option Plan provides for the grant of incentive share options, within
the meaning of Section 422 of the Internal Revenue Code, to our employees, and
for the grant of nonstatutory share options to our employees, directors and
consultants.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE 1998 STOCK OPTION PLAN. As of
June 30, 2000, a total of 5 million of our ordinary shares were reserved for
issuance pursuant to the 1998 Stock Option Plan, of which options to acquire
2,168,476 ordinary shares at a weighted average exercise price of $1.29 per
share were issued and outstanding, 1,018,574 ordinary shares had been issued
upon exercise of outstanding options and 1,812,950 ordinary shares remain
available for issuance. As of June 30, 2000, our officers and directors held
options to purchase 1,031,752 ordinary shares under the 1998 Stock Option Plan.

     ADMINISTRATION OF THE 1998 STOCK OPTION PLAN. In general, our board of
directors administers the 1998 Stock Option Plan. Our board of directors
determines the terms of the options granted, including the exercise price, the
number of ordinary shares subject to each option, the exercisability of the
options and the form of consideration payable upon exercise.

     EXERCISE PRICE AND FORM OF OPTIONS. Our board of directors determines the
exercise price of options granted under the 1998 Stock Option Plan. In the case
of an incentive share option, the exercise price must at least be equal to the
fair market value of our ordinary shares on the date of grant. In addition, the
term of an option may not exceed ten years.

     EARLY EXERCISE. On April 24, 2000, the shareholders approved amendments to
the 1998 Stock Option Plan to allow for the early exercise of options granted
pursuant to the plan. In accordance with the amendments, certain employees may,
upon the prior approval of our board of directors and in certain cases subject
to any additional consents and approvals as may be required by law, early
exercise their options prior to their vesting. The payment for the shares issued
as a result of such early exercise is subject to an installment obligation and
carries interest at the annual interest rate of 6.5%. The shares purchased by
the employees pursuant to such early exercise are deposited in escrow with a
trustee and are released to the employee by the trustee only upon the
termination of the vesting period

                                    61
<PAGE>

applicable to such shares and upon the full payment of all amounts with respe
arrangement. All payments are due upon the earlier of termination of employment
or five (5) years following the date of the early exercise of the options. We
retain a lien over such shares until their release.

     In the event of termination of the employment of an employee who has early
exercised his or her shares prior to the end of the applicable vesting period,
we may, in our sole discretion: (i) cause the forfeiture of the shares, (ii)
transfer the shares to the trustee of our Section 102 Share Option Plan or (iii)
accelerate the payment of any amounts due in respect to such shares issued under
the early exercise arrangement. Should we not exercise our right to cause the
forfeiture of the shares or to transfer the shares to the trustee of our Section
102 Share Option Plan within 90 days of the date of the termination of the
applicable employment relationship, the employee is required to immediately pay
all monies due in respect to the shares purchased pursuant to the early exercise
arrangement.

     RIGHTS UPON TERMINATION. After termination of an employee, director or
consultant, he or she may exercise his or her vested options for the period of
time stated in the option agreement. Generally, if termination is due to death
or disability, the option will remain exercisable for three months. In all other
cases, our board of directors may allow the option to remain exercisable for
three months. An option may generally not be exercised later than the expiration
of its original term.

     TRANSFERABILITY OF OPTIONS. Unless otherwise determined by the
administrator, our 1998 Stock Option Plan generally does not allow for the
transfer of options and only the optionee may exercise an option during his or
her lifetime.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. Our 1998 Stock Option Plan provides
that in the event of our merger with or into another corporation or a sale of
substantially all of our assets, the successor corporation will assume or
substitute equivalent options for each option. If the outstanding options are
not assumed or substituted, all outstanding options will accelerate and become
fully vested prior to the close of such merger or sale of assets.

     AMENDMENT AND TERMINATION OF OUR 1998 STOCK OPTION PLAN. Our 1998 Stock
Option Plan will automatically terminate on July 23, 2003, 60 months from the
day of adoption. In addition, our board of directors has the authority to amend,
suspend or terminate the 1998 Stock Option Plan, provided it does not adversely
affect any previously granted option.

     2000 SHARE OPTION PLAN

     The 2000 Share Option Plan was adopted by our board of directors and
approved by our shareholders in April 2000. The 2000 Share Option Plan provides
for the grant of incentive share options, within the meaning of Section 422 of
the Internal Revenue Code, to our employees, and for the grant of nonstatutory
share options to our employees, directors and consultants.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE 2000 SHARE OPTION PLAN. As of
June 30, 2000, we had reserved a total of 5,300,000 of our ordinary shares for
issuance pursuant to the 2000 Share Option Plan, of which options to acquire
340,000 ordinary shares at a weighted average price of $12.63 per share were
outstanding, no ordinary shares have been issued under the 2000 Share Option
Plan, all of which are being held by our officers and directors and 4,960,000
ordinary shares remain available for issuance. Our 2000 Share Option Plan
provides for annual increases in the number of shares available for issuance on
the first day of each fiscal year, beginning 2001, equal to the lesser of 5% of
the outstanding ordinary shares on the first day of each fiscal year, 1,500,000
ordinary shares or another amount determined by our board.

     ADMINISTRATION OF THE 2000 SHARE OPTION PLAN. In general, our board of
directors administers the 2000 Share Option Plan. Our board of directors
determines the terms of the options granted, including the exercise price, the
number of ordinary shares subject to each option, the exercisability of the
options and the form of consideration payable upon exercise.


     EXERCISE PRICE AND FORM OF OPTIONS. Our board of directors determines the
exercise price of options granted under the 2000 Share Option Plan. In the case
of incentive share options, the exercise price must at least be equal to the
fair market value of our ordinary shares on the date of grant. In addition, the
term of an option may not exceed ten years.


                                        62
<PAGE>


     LIMITATION ON OPTION GRANTS. No optionee may be granted an option to
purchase more than 1,500,000 ordinary shares in any fiscal year, provided
however, in connection with his or her initial service, an optionee may be
granted a one-time option to purchase up to 3,000,000 ordinary shares.

     RIGHTS UPON TERMINATION. After termination of one of our employees,
directors or consultants, he or she may exercise his or her vested options for
the period of time stated in the option agreement. Generally, if termination is
due to death or disability, the option will remain exercisable for 12 months. In
all other cases, the option will generally remain exercisable for three months.
However, an option generally may not be exercised later than the expiration of
its original term.

     TRANSFERABILITY OF OPTIONS. Unless otherwise determined by the
administrator, our 2000 Share Option Plan generally does not allow for the
transfer of options and only the optionee may exercise an option during his or
her lifetime.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. Our 2000 Share Option Plan provides
that in the event of our merger with or into another corporation or a sale of
substantially all of our assets, the successor corporation will assume or
substitute equivalent options for each option. If the outstanding options are
not assumed or substituted, all outstanding options will accelerate and become
fully vested prior to the close of such merger or sale of assets.

     AMENDMENT AND TERMINATION OF OUR 2000 SHARE OPTION PLAN. Our 2000 Share
Option Plan will automatically terminate in April 2010, unless we terminate it
sooner. In addition, our board of directors has the authority to amend, suspend
or terminate the 2000 Share Option Plan provided it does not adversely affect
any previously granted option.

     2000 EMPLOYEE SHARE PURCHASE PLAN

     The 2000 Employee Share Purchase Plan was adopted by our board of directors
and approved by our shareholders in April 2000.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE 2000 EMPLOYEE SHARE PURCHASE
PLAN. As of June 30, 2000, we had reserved a total of 750,000 of our ordinary
shares for sale under our 2000 Employee Share Purchase Plan. In addition, our
2000 Employee Share Purchase Plan provides for annual increases in the number of
ordinary shares available for issuance on the first day of each fiscal year,
beginning 2001, equal to the lesser of 2.0% of the outstanding ordinary shares
on the first day of each fiscal year, 750,000 ordinary shares or another amount
determined by our board of directors.

     ADMINISTRATION OF THE 2000 EMPLOYEE SHARE PURCHASE PLAN. Generally, our
board of directors administers the 2000 Employee Share Purchase Plan. Our board
of directors has full and exclusive authority to interpret the terms of the
purchase plan and determine eligibility.

     ELIGIBILITY TO PARTICIPATE. All of our employees are eligible to
participate if they are customarily 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 will not be granted an option to purchase
shares under the 2000 Employee Share Purchase Plan if such employee:

     o    owns shares possessing 5% or more of the total combined voting power
          or value of all classes of our capital shares immediately after grant,
          OR

     o    has rights to purchase shares under all of our employee share purchase
          plans that accrue at a rate that exceeds $25,000 worth of the value of
          the shares for each calendar year.


     OFFERING PERIODS; PARTICIPATION. Our 2000 Employee Share Purchase Plan is
intended to qualify under Section 423 of the Internal Revenue Code and contains
consecutive, overlapping 24-month offering periods. Each offering period
includes four six-month purchase periods. The offering periods generally start
on the first trading day on or after January 1st and July 1st of each year,
except for the first offering period, which will commence on the first trading
day on or after the effective date of this offering, and will end on the first
trading day on or after May 1st and November 1st.


     Our 2000 Employee Share Purchase Plan permits participants to purchase
ordinary shares through payroll deductions of up to 15% of their compensation.
For purposes of our 2000 Employee Share Purchase Plan,


                                       63
<PAGE>


compensation includes base salary, wages, overtime pay, commissions, bonuses and
other compensation paid directly to an employee. Additionally, a participant is
able to purchase a maximum of 5,000 ordinary shares under the 2000 Employee
Share Purchase Plan during a six-month purchase period.

     PURCHASE OF SHARES. Amounts deducted and accumulated by the participant
will be used to purchase full ordinary shares at the end of each six-month
purchase period. The price will be 85% of the lower of the fair market value of
our ordinary shares at the beginning of an offering period or at the end of a
purchase period. If the fair market value at the end of a purchase period is
less than the fair market value at the beginning of the offering period,
participants will be withdrawn from the current offering period following their
purchase of shares and will be automatically re-enrolled in a new offering
period. Participants may end their participation at any time during an offering
period and will be paid their payroll deductions to date. Participation in our
2000 Employee Share Purchase Plan ends automatically upon termination of
employment with us.

     TRANSFERABILITY OF RIGHTS. A participant is not able to transfer rights
granted under our 2000 Employee Share Purchase Plan other than by will, the laws
of descent and distribution or as otherwise provided under the 2000 Employee
Share Purchase Plan.

     ADJUSTMENTS UPON MERGER OR ASSET SALE. In the event of our merger with or
into another corporation or a sale of all or substantially all of our assets, a
successor corporation will assume or substitute equivalent options for each
outstanding option. If the outstanding options are not assumed or substituted,
the offering period then in progress will be shortened, and a new exercise date
will be set prior to the closing of the merger or sale of assets.

     AMENDMENT AND TERMINATION OF THE 2000 EMPLOYEE SHARE PURCHASE PLAN. Our
2000 Employee Share Purchase Plan will terminate in April 2010. However, our
board of directors has the authority to amend or terminate our 2000 Employee
Share Purchase Plan, except that, subject to certain exceptions, no such action
may adversely affect any outstanding rights to purchase shares.

APPROVAL OF CERTAIN TRANSACTIONS

     DUTIES OF OFFICE HOLDERS

       The Companies Law codifies the fiduciary duties that "office holders,"
including directors and executive officers, owe to a company. An office holder's
fiduciary duties consist of a duty of loyalty and a duty of care. The duty of
loyalty includes:

     o    avoiding any conflict of interest between the office holder's position
          in the company and his or her personal affairs;

     o    avoiding any activity that is competitive with the company;

     o    avoiding exploiting any business opportunity of the company in order
          to receive personal advantage for himself or herself or others; and

     o    revealing to the company any information or documents relating to the
          company's affairs which the office holder has received due to his or
          her position as an office holder.

     The duty of care requires an office holder to act at a level of care that a
reasonable office holder in the same position would employ under the same
circumstances. This includes the duty to utilize reasonable means to obtain:

     o    information regarding the appropriateness of a given action brought
          for his or her approval or performed by him or her by virtue of his or
          her position; and

     o    all other information of importance pertaining to the foregoing
          actions.

     An office holder is defined in the Companies Law to include a director, the
general manager or chief executive officer, chief business manager or chief
operating officer, deputy general manager or executive vice-president,
vice-president, any other officer or manager directly subordinated to the
general manager and any other person assuming the responsibilities of any of the
above mentioned positions without regard to that person's title. Each person
listed in the table under "Executive Officers and Directors" is an office
holder. Under the Companies Law, all arrangements as to compensation and terms
of service of office holders require approval of the board of directors,
provided such compensation is on market terms and that the articles of
association of the company do not provide otherwise. Arrangements regarding the
compensation and terms of service of office holders


                                       64
<PAGE>


that are not on market terms require the approval of the audit committee, prior
to the approval of the board of directors. Arrangements regarding the
compensation and terms of service of directors as such and in relation to any
other role that they may have in the company require approval of the audit
committee prior to the approval of the board of directors and the shareholders.

     The Companies Law requires that an office holder of the company promptly
disclose any personal interest that he or she may have and all related material
information known to him or her, in connection with any existing or proposed
transaction by the company. In addition, if the transaction is an extraordinary
transaction as such term is defined under the Companies Law, the office holder
must also disclose any personal interest held by the office holder's spouse,
siblings, parents, grandparents, descendants, spouse's descendants and the
spouses of any of the foregoing. In addition, the office holder must also
disclose any interest held by any corporate entity in which the office holder is
a 5% or greater shareholder, director or general manager or in which he or she
has the right to appoint at least one director or the general manager. An
extraordinary transaction is defined in the Companies Law as a transaction other
than in the ordinary course of business, otherwise than on market terms, or that
is likely to have a material impact on the company's profitability, assets or
liabilities.

     After the office holder complies with the above disclosure requirements, a
transaction that is not an extraordinary transaction requires only board
approval unless the articles of association of the company provide otherwise. If
the transaction in which the office holder has a personal interest is an
extraordinary transaction, then, in addition to any approval stipulated by the
articles of association, it must also be approved by the company's audit
committee and then by the board of directors, and, under certain circumstances,
by a meeting of the shareholders of the company. Generally, a director who has a
personal interest in a matter which is to be considered at a meeting of the
board of directors or of the audit committee may not be present during the board
of director's or audit committee's discussions and may not vote on this matter.

     DUTIES OF SHAREHOLDERS

     The Companies Law applies the same disclosure requirements to a controlling
shareholder of a public company. A shareholder that holds 25% or more of the
voting rights in the company is deemed to be a controlling shareholder if no
other shareholder owns more than 50% of the voting rights in the company.
Extraordinary transactions with a controlling shareholder or in which a
controlling shareholder has a personal interest, and the terms of compensation
of a controlling shareholder who is an office holder, require the approval of
the audit committee, the board of directors and the shareholders of the company.
The shareholder approval must include at least one-third of the shareholders who
have no personal interest in the transaction and are present, in person or by
proxy, at the meeting or, alternatively, the total shareholdings of those who
have no personal interest in the transaction who vote against the transaction
must not represent more than 1% of the voting rights in the company. The
Companies Law requires that every shareholder that participates either by proxy
or in person, in a vote regarding a transaction with a controlling member of the
company indicate whether or not that shareholder has a personal interest in the
vote in question, a failure of which results in the invalidation of that
shareholder's vote.

     Under the Companies Law, a shareholder has a duty to act in good faith
towards the company and the other shareholders of the company and to refrain
from abusing that shareholder's power in the company including, among other
things, voting in a general meeting of shareholders on the following matters:

     o    any amendment to the articles of association;

     o    an increase of the company's authorized share capital;

     o    a merger; or

     o    approval of interested party transactions, which require shareholder
          approval.

     However, under the Companies Regulations (Relief From Related Party
Transactions), 5760-2000, promulgated pursuant to the Companies Law, each of the
following transactions between a company and its controlling shareholder(s) do
not require shareholder approval:

     o    the extension of the term of an existing related party transaction
          provided that the original transaction was duly approved in accordance
          with the applicable provisions of the Israeli Companies Law or the
          Israeli Securities Law and regulations promulgated thereunder;


                                       65
<PAGE>


     o    such transaction has been approved by the audit committee and the
          board of directors as being solely for the benefit of the company;

     o    such transaction is between the company and its controlling
          shareholder(s) or a company in its or their control, provided that the
          audit committee and the board of directors approve the transaction and
          determine that the transaction is in accordance with the terms defined
          in a duly approved frame-work transaction. A frame-work transaction is
          a transaction that defines general terms under which the company may,
          in the ordinary course of business, enter into transactions of a
          similar type;

     o    such transaction is a transaction between the company and its
          controlling shareholder(s) or a corporation under its or their
          control, for the purpose of entering into a transaction with a third
          party or to submit a joint offer to conduct business with a third
          party, provided that, the audit committee and the board of directors
          have approved the transaction and that the terms of the transaction in
          relation to the company are not materially different from those
          relating to the controlling shareholder(s) or a corporation in its or
          their control, taking into account their proportionate participation
          in the transaction; or

     o    such transaction is between companies that are controlled by the same
          controlling shareholder or between the company and its controlling
          shareholder(s), provided that for each public company involved, the
          audit committee and its board of directors find that the transaction
          is in accordance with market terms, in the ordinary course of business
          and does not harm the welfare of the company.

     Further, a private placement of securities by a public company that will
increase the relative holdings of a shareholder that holds 5% or more of the
company's outstanding share capital or that will cause any person to become, as
a result of such issuance, a holder of more than 5% of the company's outstanding
share capital, requires approval by the board of directors and shareholders of
the company issuing the securities. However, in accordance with the Companies
Regulations (Relief From Related Party Transactions), 5760-2000, the approval of
the shareholders shall not be required for a private placement in which less
than 20% of the actual voting rights in the company, prior to such offer, are
granted. The definition of a private placement for the purposes of such
exemption includes private placements that are part of the same transaction or
contingent or conditioned upon a previous private placement and all private
placements effectuated by the issuing company, in the previous twelve month
periods in which: (i) the same parties (or relatives or affiliates thereof) were
involved, or (ii) the consideration thereof consists of rights to the same
assets. The private placement exemptions discussed above do not apply if a
private placement is made to a director or chief executive officer of the
issuing company or to such person or entity that shall become, as a result of
such placement, a controlling shareholder.

     The Companies Law further provides that a shareholder shall refrain from
oppressing other shareholders.

     In addition, any controlling shareholder, any shareholder who knows that it
possesses power to determine the outcome of a shareholder vote and any
shareholder who, pursuant to the provisions of a company's articles of
association, has the power to appoint or prevent the appointment of an office
holder in the company, or has any other power over the company, is under a duty
to act with fairness towards the company. A breach of the above duty of fairness
will be considered as a breach of the fiduciary duty of an office holder as
described above.

     For information concerning the direct and indirect personal interests of
some of our office holders and principal shareholders in transactions with us,
please see "Related Party Transactions" and "Description of Share
Capital--Anti-Takeover Provisions Under Israeli Law."

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Companies Law provides that an Israeli company cannot exonerate an
office holder from liability with respect to a breach of his or her duty of
loyalty, but may exonerate in advance an office holder from his or her liability
to the company, in whole or in part, with respect to a breach of his or her duty
of care. Our articles of association provide that, subject to any restrictions
imposed by the Companies Law, we may enter into an insurance contract providing
coverage for the liability of any of our office holders with respect to:

     o    a breach of his or her duty of care to us or to another person;

     o    a breach of his or her duty of loyalty to us, provided that the office
          holder acted in good faith and had reasonable grounds to assume that
          his or her act would not prejudice our interests; or


                                       66
<PAGE>


     o    a financial liability imposed upon him or her in favor of another
          person with respect to an act performed by him or her in his or her
          capacity as an office holder.

     In addition, we may indemnify an office holder against the following
expenses or liabilities imposed upon him or her in his or her capacity as an
office holder:

     o    a financial liability imposed on him or her in favor of another person
          by any judgment, including a settlement or an arbitrator's award
          approved by a court; and

     o    reasonable litigation expenses, including attorneys' fees, incurred by
          such office holder or imposed upon him or her by a court, in relation
          to proceedings instigated by us against him or her or that are
          instigated on our behalf or by another person, or as a result of a
          criminal charge from which he or she was acquitted or a criminal
          charge in which he or she was convicted for a criminal offense that
          does not require proof of intent.

     The Companies Law provides that a company may not indemnify an office
holder nor enter into an insurance contract which would provide coverage for any
monetary liability incurred as a result of any of the following:

     o    a breach by the officer holder of his or her duty of loyalty unless
          the office holder acted in good faith and had a reasonable basis to
          believe that the act would not prejudice the company;

     o    a breach by the office holder of his or her duty of care if such
          breach was committed intentionally or recklessly;

     o    an act or omission with the intent to unlawfully derive a personal
          benefit; or

     o    a fine levied against the office holder as a result of a criminal
          offense.

     Under the Companies Law, the shareholders of a company may include or amend
its articles of association to include either of the following provisions:

     o    a provision authorizing the company to grant in advance an undertaking
          to indemnify an office holder, provided that the undertaking is
          limited to specified classes of events which the board of directors
          deem foreseeable at the time of grant and limited to an amount
          determined by the board of directors to be reasonable under the
          circumstances, or

     o    a provision authorizing the company to retroactively indemnify an
          office holder.

     In addition, pursuant to the Companies Law, indemnification of, and
procurement of insurance coverage for, a company's office holders must be
approved by the audit committee and the board of directors. In the case of
directors, approval by the shareholders is also required.

     Our articles of association allow us to insure and indemnify our office
holders to the fullest extent permitted by Israeli law, provided that the
insurance or indemnification is approved by the audit committee of our board of
directors and, if required by the Companies Law, also by our shareholders. We
have procured indemnification insurance for our directors and office holders.

     In July 1998, Robert Hawk purchased 63,455 ordinary shares at $0.19 per
share pursuant to a restricted stock purchase agreement. Under the restricted
stock purchase agreement, Eran Wagner and Limor Schweitzer, each an officer and
director of the company, have the right to repurchase those ordinary shares. The
right of Eran Wagner and Limor Schweitzer to repurchase those ordinary shares
lapsed as to one-fourth of the total number of shares on the first anniversary
of the grant date and lapses as to 1/12th of the total shares each quarter
thereafter. The lapsing of the repurchase right is dependent upon the continued
service by Mr. Hawk on our board of directors.

LOANS TO OFFICERS

     In March 2000, our U.S. subsidiary, XACCT Technologies, Inc., extended a
home improvement loan to Eric Gries in the amount of $175,000 with an interest
rate of 6.45% per annum. The principal plus interest on the loan are due upon
the earlier of his date of termination or two years from the date of the loan.
We have a security interest in the proceeds of any severance payments due to Mr.
Gries under his employment agreement.

OTHER RELATED PARTY TRANSACTIONS

     In connection with his early exercise of options to purchase 467,194
ordinary shares, Richard Van Hoesen executed an installment obligation on June
18, 2000, which carries an annual interest rate of 6.5%. All payments are due
upon the earlier of the termination of Mr. Van Hoesen's employment or five (5)
years from the date of the exercise of the options. All shares issued to Mr. Van
Hoesen upon the exercise of his options have been deposited in escrow with a
trustee and will be released to Mr. Van Hoesen only upon the termination of the
vesting period applicable to such shares and the full payment of all amounts
with respect to such shares. We retain a lien over such shares until their
release. In the event of termination of Mr. Van Hoesen's employment prior to the
vesting of all the shares, we may cause the forfeiture of or transfer to the
trustee the unvested shares, or accelerate payments under the installment
obligation.

     Eran Wagner and Limor Schweitzer, who are both our directors and officers,
are each a board member of Xpert Integrated Systems Ltd. Xpert Integrated
Systems Ltd. is our Israeli reseller, and we also retain that entity to perform
our system administration tasks. In addition, both Mr. Wagner and Mr. Schweitzer

together constitute 100% of the outstanding shares of Xpert UNIX Systems Ltd.
Both Mr. Wagner and Mr. Schweitzer disclaim beneficial ownership of the
securities held by Xpert Integrated Systems Ltd. except for their proportional
interest in that entity through Xpert UNIX Systems Ltd.

     In addition, Nitsan Yanovski, one of our directors, is also a director of
Xpert Integrated Systems Ltd. While none of our other directors or officers are
affiliated with Xpert UNIX Systems Ltd. or with Xpert Integrated Systems Ltd.,
entities affiliated with Ampal American Israel Corporation own approximately 20%
of the outstanding shares of Xpert Integrated Systems Ltd.

     We have procured indemnification insurance for our directors and office
holders.

     Holders of preferred shares are entitled to certain registration rights
with respect to the ordinary shares issued or issuable upon conversion of the

terms no less favorable than could have been otherwise obtained from unrelated
third parties.

                          DESCRIPTION OF SHARE CAPITAL

DESCRIPTION OF SHARES

     Below is a summary of the material provisions governing our share capital.
This summary does not purport to be complete and is subject to the terms and
conditions of our memorandum of association and articles of association, a copy
of each of which has been filed as an exhibit to the registration statement of
which this prospectus is a part.

     As of June 30, 2000, our authorized share capital consisted of 182,630,000
voting ordinary shares, NIS 0.04 nominal value per share, 1,820,000 non-voting
ordinary shares, NIS 0.04 nominal value per share, and 20,550,000 preferred
shares, NIS 0.04 nominal value per share. Upon the closing of this offering,
assuming no exercise of the underwriters' over-allotment option, our authorized
share capital will consist of:

       o   198,180,000 voting ordinary shares, of which approximately 25,668,930
           ordinary shares will be issued and outstanding;

       o   1,820,000 non-voting ordinary shares, of which approximately
           1,385,146 non-voting ordinary shares will be issued and outstanding;
           and

       o   5,000,000 special preferred shares, of which no preferred shares will
           be issued or outstanding.

DESCRIPTION OF THE SPECIAL PREFERRED SHARES

     The special preferred shares, NIS 0.04 nominal value per share, may be
issued from time to time as shares of one or more series with distinct serial
designations approved by our board of directors. The designations include, among
others, the dividend rate and the number of ordinary shares into which the
special preferred shares are convertible. We intend to authorize 5,000,000
special preferred shares upon consummation of this offering.

DESCRIPTION OF ORDINARY SHARES

     All of our issued and outstanding voting and non-voting ordinary shares,
including the voting ordinary shares issued to certain of our employees in
accordance with the early exercise arrangement when paid for, and the voting
ordinary shares offered hereby when issued and paid for, will be, duly
authorized and validly issued, fully paid and non assessable. Neither our
memorandum of association nor our articles of association nor the laws of the
State of Israel restrict in any way the ownership or voting of ordinary shares
by non-residents of Israel except with respect to subjects of countries that are
in a state of war with Israel.

     Each non-voting ordinary share has the same rights as the voting ordinary
shares except for voting rights, including the right to receive notice of
meetings of shareholders and to participate in and vote at such meetings. Each
non-voting ordinary share is convertible at any time after the issuance of such
share at the option of the holder thereof and without payment of any additional
consideration into one fully-paid and non-assessable voting ordinary share. The
voting and non-voting ordinary shares do not have pre-emptive rights.

     LIQUIDATION AND DIVIDEND RIGHTS. If we liquidate, after satisfaction in
full of all the liabilities to our creditors, our assets will be distributed to
the holders of ordinary shares in proportion to the nominal consideration paid
by them. This liquidation right may be affected by the grant of preferential
dividend or distribution rights to the holders of our authorized special
preferred shares, if and when such shares shall be issued, or to the holders of
any other class of preferred shares that we might authorize and issue in the
future. We may declare a dividend to be paid to the holders of ordinary shares
according to their rights and interests in our profits. Under the Companies Law,
cash dividends may be paid out of retained earnings of a company and also out of
the net earnings of a company, as calculated under that law, for the two years
preceding the distribution of dividend, provided however, that there is no
reasonable concern that such distribution will prevent the company from
satisfying its existing and foreseeable obligations as they become due. The
Companies Law also permits a company to effectuate a distribution by
repurchasing its own shares provided such distribution fulfills the criteria set
forth above relating to distributions. Under our articles of association, our
board of directors may declare interim and final dividends and distributions
with respect to any fiscal period.

     VOTING, SHAREHOLDERS' MEETINGS AND RESOLUTIONS. Holders of voting ordinary
shares have one vote for each voting ordinary share held on all matters
submitted to a vote of shareholders. These voting rights may be affected by the
grant of any special voting right to the holders of our authorized special
preferred shares, if and when such shares shall be issued, or to the holders of
any other class of preferred shares that we might authorize and issue in the

                                       74
<PAGE>

future. An annual general meeting shall be held once every year and such annual
meeting must be held within a period of not more than 15 months after the last
preceding annual general meeting. According to our articles of association, the
quorum required for a general meeting of shareholders is the presence of at
least two shareholders, in person or by proxy, who together hold or represent at
least 33% of the voting rights. A meeting adjourned for lack of quorum shall be
adjourned to the same day, in the following week at the same time and the same
place unless stated otherwise in the invitation to such meeting. Under the
Companies Law, unless otherwise stated in our articles of association or
applicable law, all resolutions of shareholders require a simple majority.

     Most shareholder resolutions, including resolutions for the election of
directors, the appointment of auditors or the approval of transactions with
office holders as required by the Companies Law, will be deemed adopted if
approved by the holders of a majority of the voting power represented at the
meeting, in person or by proxy, and voting thereon. Certain corporate actions
such as: (1) amending the articles of association; (2) amending the memorandum
of association; (3) a merger or consolidation; (4) a voluntary winding up; (5)
approving changes in capitalization; and (6) authorizing a new class of shares
or changing special rights of a class of shares, will be deemed adopted only if
approved by the holders of not less than 75% of the voting power represented in
person or by proxy at the meeting and voting thereon, and in some cases 75% of
the voting power of the affected class of shares. For a discussion of
shareholder duties, please see "Management--Approval of Certain Transactions."

     TRANSFER OF SHARES AND NOTICES. Fully paid ordinary shares are issued in
registered form and may be transferred freely. Under the Companies Law, all
shareholders' meetings require prior notice of at least 21 days. Pursuant to
regulations promulgated pursuant to the Companies Law, such notice shall include
the type of the general meeting, the time and place of the meeting, the agenda,
a summary of the proposed resolutions and the record date. The notice shall also
include the formal address and telephone number of the company as well as the
places, including Internet sites, where the full text of the proposed
resolutions and proxies, if applicable, may be reviewed by the shareholders. For
the purposes of determining the shareholders entitled to notice and to vote at
the meeting, the board of directors may fix the record date not more than 40
days and not less then four days prior to the date of the general meeting.

     MODIFICATION OF CLASS RIGHTS. As long as our share capital is divided into
different classes of shares, the rights attached to any class, unless otherwise
provided by our articles of association, may be modified or abrogated only by a
resolution of our shareholders subject to the consent in writing of
three-fourths of the holders of the issued shares of that class, or with the
adoption of a resolution by 75% of those present and voting at a separate
general meeting of the holders of the shares of that class.

OPTIONS AND WARRANTS

     As of June 30, 2000, options to purchase 4,107,916 of our ordinary shares
were outstanding under our 1998 Stock Option Plan, our Section 102 Share Option
Plan, our 2000 Section 3(i) Share Option Plan and Section 3(i) of the Israeli
Income Tax Ordinance and our 2000 Share Option Plan, with a weighted average
exercise price of $2.51 per share. We also have outstanding warrants as of that
date to purchase an aggregate of 1,398,547 preferred shares at a weighted
average exercise price of $7.72 per share.

REGISTRATION RIGHTS

     After this offering, the holders of approximately 16.7 million of our
ordinary shares have certain rights to register those shares under the
Securities Act of 1933, as amended, under a rights agreement. The second amended
and restated rights agreement provides that if requested by holders of at least
50% of any class of preferred shares or at least 50% of all preferred shares
combined or ordinary shares received upon conversion or reclassification of the
preferred shares with respect to the registration of not less than that number
of registrable shares which would result in an anticipated aggregate offering
price, net of underwriting discount and commissions, greater than $5,000,000, we
will file a registration statement under the Securities Act covering all
registrable securities requested to be included. We will not be obligated to
effect a demand registration until six months after this initial public
offering. The managing underwriter may reduce the number of registrable
securities to be registered for marketing reasons. All expenses incurred in
connection with such registrations, other than underwriters' and brokers'
discounts and commissions, will be borne by us.

     In addition, if we propose to register any of our ordinary shares under the
Securities Act other than registrations relating solely to employee share option
or purchase plans or relating solely to a transaction under Rule 145 enacted
under the Securities Act, the holders of registrable securities may require us
to include all or a portion of their shares in such registration, although the
managing underwriter of any such offering has certain rights

                                       75
<PAGE>

to reduce the number of shares to be included in such registration. All expenses
incurred in connection with such registrations, other than underwriters' and
brokers' discounts and commissions, will be borne by us. The underwriters of
this initial public offering have decided to exclude all registrable securities
from this offering.

ANTI-TAKEOVER PROVISIONS UNDER ISRAELI LAW

     MERGERS AND ACQUISITIONS

     Israeli law regulates mergers, votes required to approve mergers and
acquisitions of shares through tender offers. The law requires special approvals
for transactions involving significant shareholders and regulates other matters
that are relevant to these types of transactions.

     Generally, under the Companies Law, a merger is required to be approved by
the board of directors and the shareholders of each of the merging companies. If
the share capital of the company that will not be the surviving company is
divided into different classes of shares, the approval of each class is also
required. Our articles of association requires that a merger be approved by the
holders of not less than 75% of the voting power represented in person or by
proxy at a shareholders' meeting and voting thereon. In addition, a merger can
be completed only after all approvals have been submitted to the Israeli
Registrar of Companies and 70 days have passed from the time that a proposal for
approval of the merger was filed with the Registrar.

     The Companies Law also provides that an acquisition of shares in a public
company must be made by means of a tender offer if as a result of the
acquisition the purchaser would become a 25% shareholder of the company. This
rule does not apply if there is already another 25% shareholder of the company.
Similarly, the Companies Law provides that an acquisition of shares in a public
company must be made by means of a tender offer if as a result of the
acquisition the purchaser would become a 45% shareholder of the company, unless
someone else already holds a majority of the voting power of the company. These
rules do not apply if the acquisition is made by way of a merger. Regulations
promulgated under the Companies Law provide that these tender offer requirements
do not apply to companies whose shares are listed for trading outside of Israel
if, according to the law in the country in which the shares are traded,
including the rules and regulations of the stock exchange on which the shares
are traded, either:

       o   there is a limitation on acquisition of any level of control of the
           company; or

       o   the acquisition of any level of control requires the purchaser to do
           so by means of a tender offer to the public.

     Further, Israeli tax law may treat some acquisitions, including a
stock-for-stock swap between an Israeli company and a foreign company, less
favorably than does U.S. tax law. For example, Israeli tax law may subject a
shareholder who exchanges his ordinary shares for shares in a foreign
corporation to immediate taxation.

     CLASSIFIED BOARD OF DIRECTORS

     Our Chief Executive Officer is appointed to our board of directors by
virtue of his office, subject to annual shareholder approval. The other
directors are divided into three classes. The directors in each class will serve
for staggered three-year terms. This system of electing and removing directors
may discourage a third party from making a tender offer or otherwise attempting
to obtain control of us, because a staggered board generally makes it more
difficult for shareholders to replace a majority of the directors.

     SPECIAL PREFERRED SHARES

     The authorization of undesignated preferred shares makes it possible for
the board of directors to issue preferred shares with voting or other rights or
preferences that could impede the success of any attempt to change our control.
These and other provisions may have the effect of deferring hostile takeovers or
delaying changes in our control or management.

TRANSFER AGENT AND REGISTRAR

     We have selected American Stock Transfer & Trust Company as the transfer
agent and registrar for our ordinary shares.

<PAGE>

                         SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no market for our ordinary shares.
Future sales of substantial amounts of our ordinary shares in the public market
following this offering could cause the prevailing market price of our ordinary
shares to fall and impede our ability to raise equity capital at a time and on
terms favorable to us.

     Upon completion of this offering, we will have outstanding an aggregate of
27,054,076 ordinary shares, assuming the exercise of outstanding warrants as of
June 30, 2000 to purchase 1,398,547 preferred shares, which warrants if
unexercised would expire upon the closing of this offering, but no exercise of
the underwriters' over-allotment option and no exercise of outstanding options
or any other outstanding warrants after June 30, 2000. Of these outstanding
shares, the 5,000,000 shares sold in this offering will be freely tradable
without restriction or further registration under the Securities Act of 1933, as
amended, unless purchased by our affiliates, as that term is defined in Rule 144
under the Securities Act. The remaining 22,054,076 ordinary shares outstanding
upon completion of this offering and held by existing shareholders will be
"restricted securities" as that term is defined in Rule 144 under the Securities
Act. Restricted shares may be sold in the public market only if registered or if
they qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, which rules are summarized below, or
another exemption. Sales of restricted shares in the public market, or the
availability of such shares for sale, could adversely affect the market price of
our ordinary shares.

LOCK-UP AGREEMENT

     All officers, directors and holders of our ordinary shares and preferred
shares have entered into contractual "lock-up" agreements providing that they
will not offer, sell, contract to sell or grant any option to purchase or
otherwise dispose of ordinary shares owned by them or that could be purchased by
them through the exercise of options or warrants for a period of 180 days after
the date of this prospectus without the prior written consent of Credit Suisse
First Boston Corporation. As a result of these contractual restrictions,
notwithstanding possible earlier eligibility for sale under the provisions of
Rules 144, 144(k) and 701, additional shares will be available beginning 181
days after the effective date of this offering, subject in some cases to certain
volume limitations.

RULE 144

     In general, under Rule 144 as currently in effect, beginning 91 days after
the date of this prospectus, a person, or persons whose shares are aggregated,
who has beneficially owned restricted shares for at least one year, including
persons who may be deemed to be our affiliates, would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of:

       o   1% of the number of ordinary shares then outstanding, which will
           equal approximately 270,541 shares immediately after this offering;
           or

       o   the average weekly trading volume of the ordinary shares as reported
           through The Nasdaq Stock Market's National Market during the four
           calendar weeks preceding the filing of a Form 144 with respect to
           such sale.

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

RULE 144(K)

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

RULE 701

     Subject to certain limitations on the aggregate offering price of a
transaction and other conditions, Rule 701 permits resales of shares issued
prior to the date the issuer becomes subject to the reporting requirements of
the Securities Exchange Act of 1934, as amended, pursuant to certain
compensatory benefit plans and contracts commencing 90 days after the issuer
becomes subject to the reporting requirements of the Exchange Act, in reliance
upon Rule 144 but without compliance with certain restrictions, including the
holding period requirements. In addition, the Securities and Exchange Commission
has indicated that Rule 701 will apply to typical stock options granted by an
issuer before it becomes subject to the reporting requirements of the Exchange
Act, along with the shares acquired upon exercise of such options, including
exercises after the date the issuer becomes so subject. Securities issued in
reliance on Rule 701 are restricted securities and, subject to the contractual
restrictions described above, beginning 91 days after the date of this
prospectus, may be sold by persons other than affiliates subject only to the
manner of sale provisions of Rule 144 and by affiliates under Rule 144 without
compliance with its one-year minimum holding period requirements.

     We have entered into an agreement with the underwriters that we will not
sell or otherwise dispose of any ordinary shares or any securities convertible
into or exercisable or exchangeable for ordinary shares, or enter into any swap
or similar agreement that transfers, in whole or in part, the economic risk of
ownership of the ordinary shares, for a period of 180 days after the date of
this prospectus, without the prior written consent of Credit Suisse First Boston
Corporation, subject to limited exceptions.

REGISTRATION OF SHARES ISSUED IN CONNECTION WITH COMPENSATORY OPTION PLANS

     We intend to file a registration statement under the Securities Act
covering the ordinary shares subject to outstanding options or reserved for
issuance under the share option plans and share purchase plans. Upon the
effectiveness of such registration statement, all such shares will, subject to
Rule 144 volume limitations applicable to affiliates and the expiration of a
180-day lockup period, be available for sale in the open market, except to the
extent that such shares are subject to our vesting restrictions or the
contractual restrictions described above.

                             U.S. TAX CONSIDERATIONS

     The following describes the material United States federal income tax
consequences of the purchase, ownership and disposition of the ordinary shares
to a U.S. holder.

       For purposes of this discussion, a U.S. holder is:

       o   an individual citizen or resident of the United States;

       o   a corporation or other entity taxable as a corporation created or
           organized under the laws of the United States or any political
           subdivision thereof;

       o   an estate, the income of which is includable in gross income for
           United States federal income tax purposes regardless of its source;
           or

       o   a trust, if (1) a United States court is able to exercise primary
           supervision over its administration and one or more United States
           persons have the authority to control all of its substantial
           decisions, or (2) the trust was in existence on August 20, 1996 and
           has properly elected to continue to be treated as a United States
           person.

     This summary is for general information only and does not purport to be a
comprehensive description of all of the federal income tax considerations that
may be relevant to a decision to purchase the ordinary shares. This summary
generally considers only U.S. holders that will own the ordinary shares as
capital assets. This summary does not consider the United States tax
consequences to a person that is not a U.S. holder.

     This discussion is based on current provisions of the Internal Revenue Code
of 1986, as amended, or the Code, current and proposed Treasury regulations
issued under the Code, and administrative and judicial interpretations of the
Code, all as in effect today and all of which are subject to change, possibly
with a retroactive effect. This discussion does not address all aspects of U.S.
federal income taxation that may be relevant to any particular U.S. holder based
on the U.S. holder's particular circumstances. In particular, this discussion
does not address the tax treatment of U.S. holders:

       o   who are broker-dealers;

       o   who own, directly, indirectly or constructively, 10% or more of our
           outstanding voting shares;

       o   holding the ordinary shares as part of a hedging, straddle or
           conversion transaction;

       o   whose functional currency is not the dollar; and

       o   who may be subject to special tax rules not discussed below,
           including insurance companies, tax-exempt organizations, financial
           institutions and persons subject to the alternative minimum tax.

     Additionally, the tax treatment of persons who hold the ordinary shares
through a partnership or other pass-through entity is not considered, nor are
the possible application of U.S. federal estate or gift taxes or any aspect of
state, local or non-U.S. tax laws.

     You are advised to consult your own tax advisor with respect to the
specific U.S. federal income tax consequences to you of purchasing, holding or
disposing of the ordinary shares.

DISTRIBUTIONS ON THE ORDINARY SHARES

     The amount of a distribution with respect to the ordinary shares will equal
the amount of cash and the fair market value of any property distributed and
will also include the amount of any Israeli taxes withheld as described below
under "Israeli Taxation--Withholding and Capital Gains Taxes Applicable to
Non-Israeli Shareholders." In general, a distribution paid by us with respect to
the ordinary shares to a U.S. holder will be treated as ordinary dividend income
to the extent that the distribution does not exceed our current and accumulated
earnings and profits, as determined for U.S. federal income tax purposes. The
amount of any distribution which exceeds these earnings and profits will be
treated first as a non-taxable return of capital, reducing the U.S. holder's tax
basis in its ordinary shares to the extent thereof, and then as capital gain.
Corporate holders generally will not be allowed a deduction for dividends
received on ordinary shares.

                                       79
<PAGE>

     A dividend paid by us in NIS will be included in the income of U.S. holders
at the dollar amount of the dividend, based upon the spot rate of exchange in
effect on the date of the distribution. U.S. holders will have a tax basis in
the NIS for U.S. federal income tax purposes equal to that dollar value. Any
subsequent gain or loss on the NIS arising from exchange rate fluctuations will
be taxable as ordinary income or loss and will be U.S. source income or loss.

     Dividends paid by us generally will be foreign source passive income for
U.S. foreign tax credit purposes or, in the case of a U.S. holder that is a
financial services entity, financial services income. Subject to the limitations
in the Code, U.S. holders may elect to claim as a foreign tax credit against
their U.S. federal income tax liability the Israeli income tax withheld from
dividends received on the ordinary shares. U.S. holders that do not elect to
claim a foreign tax credit may instead claim a deduction for Israeli income tax
withheld. The rules relating to foreign tax credits are complex, and you should
consult your own tax advisor to determine whether and to what extent you would
be entitled to this credit.

DISPOSITION OF THE ORDINARY SHARES

     Upon the sale, exchange or other disposition of the ordinary shares, a U.S.
holder generally will realize capital gain or loss in an amount equal to the
difference between the amount realized on the disposition and the U.S. holder's
tax basis in the ordinary shares. The gain or loss recognized on the sale,
exchange or other disposition of the ordinary shares generally will be long-term
capital gain or loss if the U.S. holder held the ordinary shares for more than
one year at the time of the disposition.

     Gain or loss recognized by a U.S. holder on a sale, exchange or other
disposition of ordinary shares generally will be treated as U.S. source income
or loss for U.S. foreign tax credit purposes.

PASSIVE FOREIGN INVESTMENT COMPANIES

     We believe that we were not a passive foreign investment company in 1999
and do not expect to become a passive foreign investment company. However, the
factual determination of our passive foreign investment company status is made
annually and thus may be subject to change. Therefore, we cannot assure you that
we will not become a passive foreign investment company in 2000 or in a future
year.

     PASSIVE FOREIGN INVESTMENT COMPANY STATUS

     In general, we will be a passive foreign investment company if for any of
our taxable years in which you held ordinary shares:

       o   at least 75% of our gross income for the taxable year is passive
           income; or

       o   at least 50% of the value, determined on the basis of a quarterly
           average, of our assets is attributable to assets that produce or are
           held for the production of passive income.

     Passive income generally includes dividends, interest, some types of
royalties and rents and gains from the sale or exchange of assets that produce
passive income. Cash and other current assets readily convertible into cash will
be treated as passive assets for purpose of the asset test. If we own directly
or indirectly at least 25% by value of the stock of another corporation, we will
be treated for purposes of the passive foreign investment company tests as
owning our proportionate share of the other corporation's assets and as directly
earning our proportionate share of the other corporation's income.

     EFFECTS OF PASSIVE FOREIGN INVESTMENT COMPANY STATUS

     If we were classified as a passive foreign investment company, and you did
not make either a mark-to-market election or a qualified electing fund election,
each as described below, you would be subject to special rules for:

       o   any gain you realize on the sale or other disposition of your
           ordinary shares; and

       o   any excess distribution that we make to you, which means any
           distribution you receive on the shares in a taxable year that is
           greater than 125% of the average annual distribution received by you
           on our ordinary shares in the three preceding taxable years or your
           holding period for the ordinary shares, if shorter.

                                       80
<PAGE>

       Under these special tax rules:

       o   the gain or excess distribution would be allocated ratably over your
           holding period for the ordinary shares;

       o   the amount allocated to the taxable year in which you realized the
           gain or excess distribution and any taxable year before the first
           taxable year in which we were classified as a passive foreign
           investment company would be treated as ordinary income and subject to
           tax at the rates currently applicable to ordinary income;

       o   the amount allocated to each of the other years would be subject to
           tax at the highest tax rate applicable to ordinary income in effect
           for that year; and

       o   the interest charge applicable to underpayments of tax would be
           imposed on the resulting tax attributable to each year before the
           current year in which we were classified as a passive foreign
           investment company.

     To avoid this tax consequence, a U.S. holder may elect to mark-to-market
the ordinary shares. If you make this election:

       o   you will include as ordinary income each year the excess, if any, of
           the fair market value of your ordinary shares at the end of the
           taxable year over your adjusted taxable basis in your ordinary
           shares, and you will recognize additional gain, if any, on the sale
           or other disposition of your ordinary shares as ordinary income for
           that taxable year;

       o   you will be allowed to claim a deduction as an ordinary loss for the
           excess, if any, of the adjusted taxable basis of your ordinary shares
           over their fair market value at the end of the taxable year or over
           their final sale or disposition price, but only to the extent of the
           net amount of previously included income that results from the
           mark-to-market election; and

       o   your basis in the ordinary shares will be adjusted to reflect any
           income or loss amounts.

     However, if we were classified as a passive foreign investment company,
persons who inherit the ordinary shares from you would not receive the normally
available increase in the tax basis in the ordinary shares to fair market value
as of the date of death, even if you have made the mark-to-market election.

     Under some circumstances, U.S. holders in a passive foreign investment
company may make a qualified electing fund election as an alternative to the
mark-to-market election described above. If you make a qualified electing fund
election, you would not be subject to the passive foreign investment company
rules described above. Instead, you generally would be required to include in
your taxable income some undistributed amounts of our income. However, we do not
currently intend to take actions necessary for a U.S. holder to make a qualified
electing fund election if we are determined to be a passive foreign investment
company.

     If you own ordinary shares during any year that we are a passive foreign
investment company, you must file with your U.S. income tax return IRS Form 8621
for distributions received on the ordinary shares and any gain realized on the
disposition of the ordinary shares.

     Neither we nor our advisors has any duty to, or will undertake to inform,
U.S. holders of change in circumstances that would cause us to become a passive
foreign investment company. U.S. holders should consult their own tax advisors
concerning our status as a passive foreign investment company at any time after
the date of this prospectus.

BACKUP WITHHOLDING

     A U.S. holder may be subject to backup withholding at a rate of 31% with
respect to dividend payments and proceeds from the disposition of the ordinary
shares. In general, backup withholding will apply only if a U.S. holder fails to
comply with certain identification procedures. Backup withholding will not apply
with respect to payments made to certain exempt recipients, such as corporations
and tax-exempt organizations. Backup withholding is not an additional tax and
may be claimed as a credit against the U.S. federal income tax liability of a
U.S. holder. Alternatively, the U.S. holder may be eligible for a refund of any
excess amounts withheld under the backup withholding rules. In either case, the
required information must be furnished to the Internal Revenue Service.

                                ISRAELI TAXATION

     The following is a summary of the current tax issues relating to companies
in Israel, with special reference to its effect on us. The following also
contains a discussion of certain Israeli tax consequences to persons purchasing
the ordinary shares offered hereby and certain Israeli Government programs
benefiting us. To the extent that the discussion is based on new tax legislation
that has not been subject to judicial or administrative interpretation, we
cannot assure you that the views expressed in the discussion will be accepted by
the tax authorities in question. The discussion is not intended, and should not
be construed, as legal or professional tax advice and is not exhaustive of all
possible tax considerations. You should consult your own tax advisors as to the
Israeli or other tax consequences of the purchase, ownership and disposition of
ordinary shares, including, in particular, the effect of any foreign, state or
local taxes.

     You are urged to consult your own tax advisors about the Israeli or other
tax consequences of the purchase, ownership and disposition of our ordinary
shares, including, in particular, the effect of any foreign, state or local
taxes.

GENERAL CORPORATE TAX STRUCTURE

     Israeli companies are subject to corporate tax at a rate of 36%. However,
the effective rate of tax of a company that derives income from an approved
enterprise, as defined below, may be considerably lower.

LAW FOR THE ENCOURAGEMENT OF INDUSTRY (TAXES), 1969

     We currently qualify as an "industrial company" under the Law for the
Encouragement of Industry (Taxes), 1969, or the Industry Encouragement Law. A
company qualifies as an "industrial company" if it is resident in Israel and at
least 90% of its income in a given tax year, exclusive of income from certain
loans, marketable securities, capital gains, interest and dividends, is derived
from industrial enterprises owned by it. An "industrial enterprise" is defined
as an enterprise whose major activity in a particular tax year is industrial
manufacturing.

     Under the Industry Encouragement Law, an industrial company is entitled to
deduct the purchase price of patents and certain other intangible property
rights, other than goodwill, over a period of eight years, beginning with the
year in which such rights were first used, and to deduct public offering
expenses ratably over a period of three years.

     An industrial company may be eligible for special depreciation rates for
machinery, equipment and buildings. These rates vary, based on various factors,
including the date of commencement of operation and the number of works shifts.
An industrial company owning an approved enterprise may choose between such
special depreciation rates and the depreciation rates available to approved
enterprises.

     Qualification as an industrial company under the Industry Encouragement Law
is not conditioned upon the receipt of prior approval from any Israel government
authority. We cannot assure you that we will continue to qualify as an
industrial company or that we will, in the future, be able to take advantage of
any tax benefits available to industrial companies.

LAW FOR THE ENCOURAGEMENT OF CAPITAL INVESTMENTS, 1959

     The Law for the Encouragement of Capital Investments, 1959, or the
Investment Law, provides that a capital investment in eligible facilities may,
upon application to the Investment Center of the Ministry of Industry and
Commerce of the State of Israel, be designated as an approved enterprise. Each
certificate of approval for an approved enterprise relates to a specific
investment program delineated both by its financial scope, including its capital
resources, and by its physical characteristics, such as the equipment to be
purchased and utilized pursuant to the program. The tax benefits derived from
any such certificate of approval relate only to taxable income attributable to
the specific approved enterprise. If a company has more than one approval or
only a portion of its capital investments is approved, its effective tax rate is
the result of a weighted average of the applicable rates.

     We have been granted the status of an "approved enterprise" under the
Investment Law, and we qualify as a "foreign investors' company" as defined in
the Investment Law. We have elected to receive the alternative package of
benefits under the Investment Law. Under the terms of our approved enterprise
program, our income from the approved enterprise will be tax exempt for a period
of two years, commencing with the year in which we first earn


                                       82

<PAGE>


taxable income, and subject to a reduced corporate tax rate of between 10% and
20% (depending on the level of foreign investment in the company) for an
additional period of up to a total of eight years, provided that the total
period of tax benefits will not extend past the earlier of (1) 12 years from the
year of commencement of production or (2) 14 years from the year of approval of
the approved enterprise status. The initial two-year period of benefit has not
yet commenced.

     If dividends are paid out of tax-exempt profit derived from our approved
enterprise, we will be liable for corporate tax at the rate that would have been
applied if we had not elected the alternative tax benefit. This rate is
generally 10% to 20%, depending on the percentage of the company's shares held
by foreign shareholders. We will also be required to withhold on behalf of the
dividend recipients an additional 15% of the amount distributed as dividends.
Cash dividends paid by an Israeli company are normally subject to a withholding
tax, except for dividends that are paid to an Israeli company, in which case no
tax is withheld unless the dividend is paid in respect of earnings from an
approved enterprise. In addition, because we have received certain benefits
under Israeli laws relating to approved enterprise, payment of dividends may
subject us to certain Israeli taxes to which we would not otherwise be subject.
The tax-exempt income attributable to the approved enterprise can be distributed
to shareholders without subjecting us to taxes only upon our complete
liquidation.

     The Investment Law also provides that an approved enterprise is entitled to
accelerated tax depreciation on property and equipment included in an approved
investment program.

     Any future applications we make to the Investment Center will be reviewed
separately, and decisions as to whether or not to approve such applications will
be based, among other things, on the then prevailing criteria set forth in the
Investment Law, on the specific objective we set forth in such applications and
on certain financial criteria. Accordingly, we cannot assure you that any such
applications will be approved. In addition, the benefits available to an
approved enterprise are conditional upon our fulfilling certain conditions
stipulated in the Investment Law and its regulations and the criteria set forth
in the specific certificate of approval. If we do not meet these conditions, in
whole or in part, we would be required to refund the amount of tax benefits,
with the addition of the Israeli CPI linkage adjustment and interest thereupon.
We believe that our approved enterprise operates in substantial compliance with
each of these conditions and criteria.

TAXATION UNDER INFLATIONARY CONDITIONS

     The Income Tax Law (Inflationary Adjustments), 1985, or the Inflationary
Adjustments Law, attempts to overcome some of the problems experienced in a
traditional tax system by an economy experiencing rapid inflation, which was the
case in Israel at the time the Inflationary Adjustments Law was enacted. The
Inflationary Adjustments Law was designed to neutralize the erosion of capital
investments in business and to prevent tax benefits resulting from deduction of
inflationary expenses. The Inflationary Adjustments Law applies a supplementary
set of inflationary adjustments to the normal taxable profits computed under
regular historical cost principles.

     The Inflationary Adjustments Law introduced a special tax adjustment for
the preservation of equity based on changes in the Israeli CPI, whereby certain
corporate assets are classified broadly into fixed (inflation-resistant) assets
and non-fixed assets. Where shareholders' equity, as such term is defined in the
Inflationary Adjustments Law, exceeds the depreciated cost of fixed assets, a
tax deduction that takes into account the effect of the annual rate of inflation
on such excess is allowed up to a ceiling of 70% of taxable income in any single
tax year, with the unused portion permitted to be carried forward on a linked
basis, without limit. If the depreciated cost of fixed assets exceeds
shareholders' equity, then such excess, multiplied by the annual inflation rate,
is added to taxable income.

     In addition, subject to certain limitations, depreciation deductions on
fixed assets and losses carried forward are adjusted for inflation on the basis
of changes in the Israeli CPI. Under the Inflationary Adjustments Law, results
for tax purposes are measured in real terms, in accordance with changes in the
Israeli CPI.

     We are taxed under this law. The discrepancy between the change in (1) the
Israeli CPI and (2) the exchange rate of Israeli currency in relation to the
dollar, may in future periods cause significant differences between taxable
income, as determined for Israeli tax purposes, and the income measured in U.S.
dollars as reflected by our consolidated financial statements, which are
measured in U.S. dollars.


                                       83

WITHHOLDING AND CAPITAL GAINS TAXES APPLICABLE TO NON-ISRAELI SHAREHOLDERS

     The State of Israel imposes income tax on non-residents of Israel on income
accrued or derived from sources in Israel or received in Israel. The sources of
income include passive income such as dividends, royalties and interest, as well
as non-passive income from business conducted or services rendered in Israel.
Upon distribution of dividends other than bonus shares, i.e., stock dividends,
income tax is generally withheld at the rate of 25%, or at the rate of 15% for
dividends distributed out of income generated by an approved enterprise, unless
a different rate is provided in a treaty between Israel and the shareholder's
country of residence. Under the income tax treaty between the United States and
Israel, the maximum tax on dividends paid to a holder of ordinary shares who is
a qualifying U.S. resident is 25%.

     Israeli law imposes a capital gains tax on the sale of securities and other
capital assets. Under current law, however, sales by an individual of the
ordinary shares offered by this prospectus are exempt from Israeli capital gains
tax for so long as the shares are quoted on Nasdaq or listed on a stock exchange
recognized by the Israeli Ministry of Finance, provided that we continue to
qualify as an industrial company, and provided further that the individual does
not hold such shares for business purposes. Please see "Law for Encouragement of
Industry (Taxes), 1969." If we do not maintain our status as an industrial
company then, subject to any applicable tax treaty, the Israeli capital gain tax
rates would be up to 50% for non-Israeli resident individuals and 36% for
corporations.

     Under the Israel-U.S. treaty, a holder of ordinary shares who is a U.S.
resident generally will be exempted from Israeli capital gain tax on the sale of
ordinary shares if such holder owned, directly or indirectly, shares
representing less than 10% of our voting power throughout the 12-month period
before the sale. Under certain circumstances specified in the treaty, if Israeli
capital gains tax is payable, it can be credited against U.S. federal tax,
subject to limitations in U.S. tax law applicable to foreign tax credits.

     A non-resident of Israel who receives interest, dividend or royalty income
derived from or accrued in Israel, from which Israeli tax was withheld at
source, is generally exempted from the duty to file tax returns in Israel with
respect to such income, provided such income was not derived from a business
conducted in Israel by such person and such person has no other non-passive
income from sources within Israel.

     Israel presently has no estate or gift tax. However, an expert committee
appointed by the Israeli Government and chaired by the General Manager of the
Finance Ministry has recommended the implementation of a gifts tax and an estate
tax. As of the date of this prospectus, the recommendation has not been
implemented into legislation by the Israeli Parliament.

PENDING TAX REFORMS

     In May 2000, an expert committee appointed by the Israeli Government and
chaired by the General Manager of the Finance Ministry recommended substantial
reforms to the Israeli tax system and tax laws. The recommendations have not
been implemented into legislation. The implementation of these recommendations
requires that a draft bill incorporating the recommendations be adopted by the
Israeli Parliament. The expert committee recommended among other things: (a)
broadening the categories of taxable income and to lower the tax rates
applicable to the ordinary income of individuals; (b) imposing a tax on the
income of Israeli residents regardless of the territorial source of such income;
(c) subject to applicable treaties for the prevention of double taxation,
applying a general tax rate of up to 25% on capital gains recognized in Israel
and reconsidering the scope of certain exemptions currently available to Israeli
residents on capital gains derived from the sale of shares of companies listed
on specified non-Israeli stock exchanges, including The Nasdaq Stock Market's
National Market; (d) imposing a gift tax and an estate tax; (e) eliminating the
additional reductions in corporate tax rates that are currently available under
the Investment Law and which depend on the percentage of foreign investment in a
company's share capital; (f) imposing a 25% tax rate on income derived from
approved enterprises with respect to any company regardless of the percentage of
foreign investment in such company's share capital; and (g) eliminating the tax
exemption available under the alternative benefits program of the Investment Law
and imposing a reduced tax rate of 10% to companies electing the alternative
benefits program. There is no certainty that the recommendations of the
committee will be adopted in whole or in part by the Israeli Parliament.

                              CONDITIONS IN ISRAEL

     We are incorporated under the laws of the State of Israel, and
substantially all of our research and development facilities, and certain
Israeli and non-U.S. operations are managed from the State of Israel.
Accordingly, we are directly affected by economic, political and military
conditions in Israel. Our operations may be materially adversely affected if
major hostilities involving Israel arise or if trade between Israel and its
present trading partners is curtailed.

POLITICAL CONDITIONS

     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 from time to time in intensity and degree, has led to
security and economic problems for Israel. Additionally, from time to time since
December 1987, Israel has experienced civil unrest, primarily in the West Bank
and Gaza Strip territories administered by Israel since 1967. A peace agreement
between Israel and Egypt was signed in 1979, a peace agreement between Israel
and Jordan was signed in 1994 and, since 1993, several agreements between Israel
and Palestinian representatives have been signed. As of the date hereof, Israel
has not entered into any peace agreement with Syria or Lebanon, and there have
been delays in the negotiations and implementation of the agreements with the
Palestinians. However, Israel has recently been engaged in peace talks with
Syria under the good auspices of the United States government. We cannot predict
how the peace process will develop or what effect that it may have upon the
company.

     Certain countries, companies and organizations continue to participate in a
boycott of Israeli firms and others doing business in Israel or with Israeli
companies. Although we are precluded from marketing our products to these
countries, we believe that in the past the boycott has not had a material
adverse effect on us. We cannot assure you that restrictive laws, policies or
practices directed towards Israel or Israeli businesses will not have an adverse
impact on the expansion of our business.

     Generally, all male adult citizens and permanent residents of Israel under
the age of 54 are, unless exempt, obligated to perform up to 36 days of military
reserve duty annually. Additionally, all such residents are subject to being
called to active duty at any time under emergency circumstances. Some of our
male officers and employees are currently obligated to perform annual reserve
duty. Although we have operated effectively under these requirements, we cannot
assess the full impact of these requirements on our workforce or business if
conditions should change, and we cannot predict the impact on us of any
expansion of such obligations.

TRADE RELATIONS

     Israel is a member of the United Nations, the International Monetary Fund,
the International Bank for Reconstruction and Development, and the International
Finance Corporation. Israel is a member of the World Trade Organization and is a
signatory to the General Agreement on Trade in Services. In addition, Israel has
been granted preferences under the Generalized System of Preferences from the
United States, Australia and Canada. These preferences allow Israel to export
products covered by such program either duty-free or at reduced tariffs.

     Israel has entered into preferential trade agreements with the European
Union, the United States and the European Free Trade Association. In recent
years, Israel has established commercial and trade relations with a number of
other nations, including China, India, Russia and other nations in Asia and
Eastern Europe, with which Israel had not previously had such relations.

ECONOMIC CONDITIONS

     Israel's economy has been subject to numerous destabilizing factors,
including a period of rampant inflation in the early to mid-1980s, low foreign
exchange reserves, fluctuations in world commodity prices, military conflicts
and civil unrest. The Israeli government, for these and other reasons, has
intervened in the economy by utilizing, among other means, fiscal and monetary
policies, import duties, foreign currency restrictions and control of wages,
prices and foreign currency exchange rates. The Israeli government has in the
past periodically changed its policies in all these areas. During 1997, the
monetary policy of the Bank of Israel changed in several respects. These changes
included a decision of the Bank of Israel to reduce its intervention in the
currency markets to allow the NIS to trade more freely. In addition, the Bank of
Israel has adopted and implemented certain measures to liberalize foreign
currency regulations. There are currently no Israeli currency control
restrictions on remittance of dividends or the

                                       85

proceeds from the sale of the ordinary shares, although legislation remains in
effect pursuant to which currency controls may be imposed by administrative
action at any time.

     The Israeli government's monetary policy contributed to relative price and
exchange rate stability in recent years, despite fluctuating rates of economic
growth and unemployment. The Israeli inflation rates for the years 1997, 1998
and 1999 were 7.0%, 8.6% and 1.3%, respectively. We cannot assure you that the
Israeli government will be successful in its attempts to keep prices and
exchange rates stable.

                                  UNDERWRITING

     Under the terms and subject to the conditions contained in an underwriting

for whom Credit Suisse First Boston Corporation, Chase Securities Inc. and U.S.
Bancorp Piper Jaffray Inc. are acting as representatives, the following
respective numbers of ordinary shares:

                                                             ===========

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

     We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 750,000 additional shares from us at the initial public
offering price less the underwriting discounts and commissions. The option may
be exercised only to cover any over-allotments of ordinary shares.

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

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

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

     We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933,
as amended relating to, any of our ordinary shares or securities convertible
into or exchangeable or exercisable for any of our ordinary shares, or publicly
disclose the intention to make any such offer, sale, pledge, disposition or
filing, without the prior written consent of Credit Suisse First Boston
Corporation for a period of 180 days after the date of this prospectus.

     Our officers and directors and certain other shareholders, including
holders of our ordinary shares and preferred shares, have agreed that they will
not offer, sell, contract to sell, pledge or otherwise dispose of, directly of
indirectly, any of our ordinary shares or securities convertible into or
exchangeable or exercisable for any of our ordinary shares, or publicly disclose
the intention to make any such offer, sale, pledge or disposition, without, in
each case, the prior written consent of Credit Suisse First Boston Corporation
for a period of 180 days after the date of this prospectus.

     The underwriters have reserved for sale, at the initial public offering
price, up to 250,000 shares of ordinary shares for employees, directors and
certain other persons associated with us who have expressed an interest in
purchasing ordinary shares in this offering. The number of shares available for
sale to the general public in this offering will be reduced to the extent such
persons purchase such reserved shares. Any reserved shares not so purchased will
be offered by the underwriters to the general public on the same terms as the
other shares.

                                       87
<PAGE>


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

     We have applied to list the ordinary shares on The Nasdaq Stock Market's
National Market under the symbol "XCCT."

     In March 2000, we sold Series D preferred shares in a private placement at
a purchase price of $12.63 per share. In this private placement, an entity
affiliated with Credit Suisse First Boston Corporation purchased 23,752 ordinary
shares, individuals and entities affiliated with Chase Securities Inc. purchased
an aggregate of 7,917 ordinary shares and individuals affiliated with U.S.
Bancorp Piper Jaffray purchased an aggregate of 7,917 ordinary shares. These
organizations purchased the Series D preferred shares on the same terms as the
other investors in the private placement.

     Prior to this offering, there has been no public market for our ordinary
shares. The initial public offering price for the ordinary shares will be
determined by negotiation between us and the underwriters, and does not reflect
the market price for the ordinary shares following this offering. Among the
principal factors to be considered in determining the initial public offering
price will be:

       o   the information in this prospectus and otherwise available to the
           underwriters;

       o   market conditions for initial public offerings;

       o   the history of and prospects for the industry in which we will
           compete;

       o   the ability of our management;

       o   our prospects for future earnings;

       o   the present state of our development and our current financial
           condition;

       o   the recent market prices of, and the demand for, publicly traded
           ordinary shares of generally comparable companies; and

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

     In connection with this offering, the underwriters may engage in
stabilizing transactions, over-allotment transactions, syndicate covering
transactions and penalty bids in accordance with Regulation M under the
Securities Exchange Act of 1934, as amended.

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

       o   Over-allotment involves sales by the underwriters of shares in excess
           of the number of shares the underwriters are obligated to purchase,
           which creates a syndicate short position. The short position may be
           either a covered short position or a naked short position. In a
           covered short position, the number of shares over-allotted by the
           underwriters is not greater than the number of shares, which they may
           purchase in the over-allotment option. In a naked short position, the
           number of shares involved is greater than the number of shares in the
           over-allotment option. The underwriters may close out any short
           position by either exercising their over-allotment option and/or
           purchasing shares in the open market.

       o   Syndicate covering transactions involve purchases of the ordinary
           shares in the open market after the distribution has been completed
           in order to cover syndicate short positions. In determining the
           source of shares to close out the short position, the underwriters
           will consider, among other things, the price of shares available for
           purchase in the open market as compared to the price at which they
           may purchase shares through the over-allotment option. If the
           underwriters sell more shares than could be covered by the
           over-allotment option--a naked short position--that position can only
           be closed out by buying shares in the open market. A naked short
           position is more likely to be created if the underwriters are
           concerned that there may be downward pressure on the price of the
           shares in the open market after pricing that could adversely affect
           investors who purchase in the offering.

       o   Penalty bids permit the representatives to reclaim a selling
           concession from a syndicate member when the ordinary shares
           originally sold by the syndicate member is purchased in a stabilizing
           or syndicate covering transaction to cover syndicate short positions.

                                       88
<PAGE>

     These stabilizing transactions, over-allotment transactions, syndicate
covering transactions and penalty bids may have the effect of raising or
maintaining the market price of the ordinary shares or preventing or retarding a
decline in the market price of the ordinary shares. As a result, the price of
the ordinary shares may be higher than the price that might otherwise exist in
the open market. These transactions may be affected on The Nasdaq Stock Market's
National Market or otherwise and, if commenced, may be discontinued at any time.

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

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

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

REPRESENTATIONS OF PURCHASERS

     Each purchaser of ordinary shares in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom the
purchase confirmation is received that: (i) such purchaser is entitled under
applicable provincial securities laws to purchase the ordinary shares without
the benefit of a prospectus qualified under the securities laws; (ii) where
required by law, such purchaser is purchasing as principal and not as agent; and
(iii) such purchaser has reviewed the text above under "Resale Restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

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

ENFORCEMENT OF LEGAL RIGHTS

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

NOTICE TO BRITISH COLUMBIA RESIDENTS

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

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of ordinary shares should consult with their own legal
and tax advisors with respect to the tax consequences of an investment in the
ordinary shares in their particular circumstances and with respect to the
eligibility of the ordinary shares for investment by the purchaser under
relevant Canadian legislation.

<PAGE>

                       ENFORCEABILITY OF CIVIL LIABILITIES

     We are incorporated in the State of Israel, and some of our officers,
directors and the Israeli experts named in this prospectus are not residents of
the United States and substantially all of their assets may be located outside
of the United States. The service of process upon, and the enforcement of
judgments against, us, our non-U.S. resident officers, directors and the Israeli
experts may be difficult.

     We have been informed by our legal counsel in Israel, S. Friedman & Co.,
that there is doubt as to the enforceability of civil liabilities under the
Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as
amended, in original actions instituted in Israel. However, subject to certain
time limitations, Israeli courts may enforce foreign, final, non-appealable
executory judgments in civil matters, including a monetary or compensatory
judgment in a non-civil matter, obtained after completion of due process before
a court of competent jurisdiction, according to the laws of the state in which
the judgment is given and the rules of private international law prevailing in
Israel. The rules of private international law currently prevailing in Israel do
not prohibit the enforcement of judgments of Israeli courts, provided that:

     o    adequate service of process has been effected and the defendant has
          had a reasonable opportunity to be heard;

     o    the judgment and the enforcement thereof are not contrary to the law,
          public policy, security or sovereignty of the State of Israel;

     o    the judgment was not fraudulently obtained and does not conflict with
          any other valid judgment in the same matter between the same parties;
          and

     o    an action between the same parties in the same matter is not pending
          in any Israeli court or tribunal at the time the lawsuit is instituted
          in the foreign court.

     We have appointed our U.S. subsidiary, XACCT Technologies, Inc., as our
agent to receive service of process in any action against us in any federal
court or court of the State of California arising out of this offering or any
purchase or sale of securities in connection with this offering. We have not
given such agent consent to accept service of process in connection with any
other claim.

     If a foreign judgment is enforced by an Israeli court, it generally will be
payable in Israeli currency, which can then be converted into non-Israeli
currency and transferred out of Israel. The usual practice in an action before
an Israeli court to recover an amount in a non-Israeli currency is for the
Israeli court to render judgment for the equivalent amount in Israeli currency
at the rate of exchange in force on the date of such judgment, but the judgment
debtor may make payment in foreign currency. Pending collection, the amount of
the judgment of an Israeli court stated in Israeli currency ordinarily will be
linked to the Israeli CPI plus interest at the annual statutory rate set by
Israeli regulations prevailing at such time.

                         REPORT OF INDEPENDENT AUDITORS

To the Shareholders of
XACCT TECHNOLOGIES LTD.

     We have audited the accompanying consolidated balance sheets of XACCT
Technologies Ltd. and its subsidiary as of December 31, 1998 and 1999 and the
related consolidated statements of operations, changes in shareholders' equity,
and cash flows for the period from June 8, 1997 (inception) to December 31,
1997, and for each of the two 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
XACCT Technologies Ltd. and its subsidiary as of December 31, 1998 and 1999, and
the consolidated results of their operations and cash flows for the period from
June 8, 1997 (inception) to December 31, 1997, and for each of the two years in
the period ended December 31, 1999, in conformity with generally accepted
accounting principles in the United States.

                             XACCT TECHNOLOGIES LTD.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               (U.S. DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)


1.   GENERAL

     XACCT Technologies Ltd. ("the Company" or "XACCT") was incorporated in
     Israel and commenced operations in June 1997.

     The Company and its U.S. wholly-owned subsidiary, XACCT Technologies Inc.,
     a Delaware corporation, develop, manufacture and market intelligent
     business infrastructure software for telecommunications carriers, Internet
     service providers, enterprise network operators, wireless service providers
     and cable network operators.

     The Company sales are made principally in North America and Europe. As for
     major customers, see Note 9.

2.   SIGNIFICANT ACCOUNTING POLICIES

     The consolidated financial statements are prepared in accordance with
     generally accepted accounting principles in the United States.

     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 consolidated financial
     statements and accompanying Notes. Actual results could differ from those
     estimates.

     FINANCIAL STATEMENTS IN U.S. DOLLARS

     A majority of the revenues of the Company and its subsidiary is generated
     in United States dollars (dollars). In addition, a substantial portion of
     the Company and its subsidiary's costs are incurred in dollars. Since the
     dollar is the primary currency in the economic environment in which the
     Company operates, the dollar is its functional and reporting currency.
     Accordingly, monetary accounts maintained in currencies other than the
     dollar are remeasured into dollars in accordance with Statement No. 52 of
     the Financial Accounting Standard Board (FASB). All transaction gains and
     losses from the remeasurement of monetary balance sheet items are reflected
     in the statement of operations as income or expenses, as appropriate.

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
     and its subsidiary. Significant inter-company transactions and balances
     were eliminated in consolidation.

     CASH EQUIVALENTS

     Cash equivalents are short-term, highly liquid investments that are readily
     convertible to cash with original maturities of three months or less.

     SHORT-TERM DEPOSITS

     Bank deposits with maturities of more than three months, but less than one
     year, are included in short-term deposits.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
               (U.S. DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)


     MARKETABLE SECURITIES

     Investments in marketable securities are accounted for in accordance with
     Statement of Financial Accounting Standards 115, "Accounting for Certain
     Investments in Debt and Equity Securities" (SFAS 115).

     The Company's marketable securities are comprised of government debentures.
     The Company classifies its marketable securities as available-for-sale.
     Unrealized losses on marketable securities in 1999 were immaterial.
     Accordingly, these losses were included in interest expense.

     PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is calculated by
     using the straight-line method over the estimated useful lives of the
     assets at the following annual rates:

                                                                   %
                                                     ---------------------------
        Computers and peripheral equipment.......                 33
        Office furniture and equipment...........                7-15
        Leasehold improvements...................     Over the term of the lease

     The Company periodically assesses the recoverability of the carrying amount
     of property and equipment and provides for any possible impairment loss
     based upon the difference between the carrying amount and fair value of
     such assets. As of December 31, 1999, no impairment indicators have been
     identified.

     RESEARCH AND DEVELOPMENT COSTS

     Research and development costs are expensed as incurred.

     Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for
     the Costs of Computer Software to be Sold, Leased or Otherwise Marketed"
     requires capitalization of certain software development costs subsequent to
     the establishment of technological feasibility. Based on the Company's
     product development process, technological feasibility is established upon
     completion of a working model. The Company does not incur any costs between
     the completion of the working model and the point at which the product is
     ready for general release. Therefore, through December 31, 1999, the
     Company has charged all software development costs to research and
     development expenses in the period in which they were incurred.

     INCOME TAXES

     The Company accounts for income taxes in accordance with SFAS No. 109,
     "Accounting for Income Taxes". This statement prescribes the use of the
     liability method, whereby deferred tax asset and liability account balances
     are determined based on differences between financial reporting and tax
     bases of assets and liabilities and are measured using the enacted tax
     rates and laws that will be in effect when the differences are expected to
     reverse. The Company provides a valuation allowance, if necessary, to
     reduce deferred tax assets to their estimated realizable value.

     REVENUE RECOGNITION

     The Company has adopted Statement of Position (SOP) 97-2, "Software Revenue
     Recognition," as amended. SOP 97-2, generally requires revenue earned on
     software arrangements involving multiple elements to be allocated to each
     element based on the relative fair value of the elements. The Company has
     also adopted SOP 98-9, "Modification of SOP 97-2, Software Revenue
     Recognition with Respect to Certain Transactions," for all transactions
     entered into after January 1, 2000. SOP 98-9 requires that revenue be
     recognized under the "residual method" when vendor specific

                                      F-8
<PAGE>


                             XACCT TECHNOLOGIES LTD.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
               (U.S. DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

     objective evidence (VSOE) of fair value exists for all undelivered elements
     and no VSOE exists for the delivered elements.

     To date, the Company has derived its revenue from license fees and
     sub-license fees of its XACCTUSAGE products, maintenance and support and
     rendering of consulting services including implementation, training and
     installation. The Company sells its products primarily through its direct
     sales force and indirectly through resellers. Revenue attributable to
     indirect sales is recognized upon acceptance by the end customer.

     Revenue from license fees is recognized when persuasive evidence of an
     agreement exists, delivery of the product has occurred, no significant
     XACCT obligations with regard to implementation remain, the fee is fixed or
     determinable, and collectibility is probable. The Company generally does
     not grant a right of return to its customers. When a right of return
     exists, the Company defers revenue until the right of return expires, at
     which time revenue is recognized provided that all other revenue
     recognition criteria have been met. The Company considers all arrangements
     with payment terms extending beyond thirty days not to be fixed or
     determinable. If the fee is not fixed or determinable, revenue is
     recognized as payments become due from the customer provided that all other
     revenue recognition criteria have been met.

     When contracts contain multiple elements wherein VSOE of fair value exists
     for all undelivered elements, the Company accounts for the delivered
     elements in accordance with the "Residual Method" prescribed by SOP 98-9.
     Maintenance and support revenue included in these arrangements is deferred
     and recognized on a straight-line basis over the term of the maintenance
     and support agreement. The VSOE of fair value of the undelivered elements
     (maintenance and support and services) is determined based on the price
     charged for the undelivered element when sold separately.

     Arrangements that include consulting services are evaluated to determine
     whether those services are essential to the functionality of other elements
     of the arrangement. When services are considered essential, revenue under
     the arrangement is recognized using contract accounting. When services are
     not considered essential, the revenue allocable to the software services is
     recognized as the services are performed. To date, the Company has
     determined that the services are not considered essential to the
     functionality of other elements of the arrangement.

     Deferred revenue includes amounts received from customers for which revenue
     has not been recognized.

     ACCOUNTING FOR STOCK-BASED COMPENSATION

     The Company has elected to follow Accounting Principles Board Opinion No.
     25 (APB 25) "Accounting for Stock Issued to Employees" in accounting for
     its employee stock option plans. Under APB 25, when the exercise price of
     the Company's share options equals or is above the market price of the
     underlying shares on the date of grant, no compensation expense is
     recognized.

     The Company applies SFAS No. 123 "Accounting for Stock-Based Compensation"
     and EITF 96-18 "Accounting for Equity Instruments that are Issued to Other
     than Employees for Acquiring, or in Conjunction with Selling, Goods or
     Services" with respect to options issued to non-employees. SFAS No. 123
     requires use of an option valuation model to measure the fair value of the
     options at the grant date. The pro forma disclosures required by SFAS No.
     123, are provided in Note 7.

     SEVERANCE PAY

     The Company's liability for severance pay is calculated pursuant to Israeli
     severance pay law based on the most recent salary of the employees
     multiplied by the number of years of employment, as of the balance sheet
     date. Employees are entitled to one month's salary for each year of
     employment or a portion thereof. The Company's liability for all of its
     employees is fully provided by monthly deposits with insurance policies and
     by an accrual.

                                      F-9
<PAGE>


                             XACCT TECHNOLOGIES LTD.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
               (U.S. DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

     The deposited funds include profits accumulated up to the balance sheet
     date. The deposited funds may be withdrawn only upon the fulfillment of the
     obligation pursuant to Israeli severance pay law or labor agreements. The
     value of the deposited funds is based on the cash surrendered value of
     these policies, and includes immaterial profits.

     FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following methods and assumptions were used by the Company in
     estimating its fair value disclosures for financial instruments:

     The carrying amounts of cash and cash equivalents, short-term deposits,
     trade receivables, and trade payables approximate their fair value due to
     the short-term maturity of such instruments. Marketable securities are
     based on the quoted market price. The carrying amounts of the Company's
     long-term deposits and the long-term loan approximate their fair value. The
     fair value was estimated using discounted cash flow analysis, based on the
     Company's incremental lendering rates for similar types of arrangements.

     BASIC AND DILUTED NET LOSS PER SHARE

     Basic net loss per share is computed based on the weighted average number
     of ordinary shares outstanding during each year. Diluted net loss per share
     is computed based on the weighted average number of ordinary shares
     outstanding during each year, plus dilutive potential ordinary shares
     considered outstanding during the year, in accordance with FASB No. 128,
     "Earnings Per Share."

     All convertible preferred shares, outstanding stock options, and warrants
     have been excluded from the calculation of the diluted net loss per share
     because all such securities are anti-dilutive for all periods presented.
     The total numbers of shares related to the outstanding convertible
     preferred shares, options and warrants excluded from the calculations of
     diluted net loss per share were 1,603,700, 11,678,660, 18,537,015,
     12,421,049 and 21,448,508 for the period from June 8, 1997 (inception) to
     December 31, 1997, for the years ended December 31, 1998 and 1999 and for
     the six months ended June 30, 1999 and 2000, respectively.

     Basic and diluted pro forma net loss per share, as presented in the
     statements of operations, has been calculated as described above and also
     gives effect to: (1) the automatic conversion of the convertible preferred
     shares into ordinary shares that will occur upon the closing of the
     offering contemplated by this prospectus (using the as-if converted
     method); and (2) the issuance of 62,086 additional ordinary shares to the
     holders of series D preferred shares in connection with anti-dilution
     adjustments.

     The following table presents the calculation of pro forma basic and diluted
     net loss per share:

     UNAUDITED PRO FORMA SHAREHOLDERS' EQUITY


     If the offering contemplated by this prospectus is consummated, all of the
     convertible preferred shares outstanding will automatically be converted
     into ordinary shares and all of the warrants outstanding will be exercised
     into shares. Pro forma shareholders' equity at June 30, 2000, as adjusted
     for the assumed conversion and exercise of those shares and warrants
     outstanding at June 30, 2000, is disclosed on the balance sheet.

     CONCENTRATIONS OF CREDIT RISK

     Financial instruments that potentially subject the Company to
     concentrations of credit risk consist principally of cash, cash equivalent,
     short-term bank deposits, marketable securities and trade receivables. Cash
     and cash equivalents and short-term bank deposit are deposited with major
     banks in Israel and in the United States. Such deposits in the United
     States may be in excess of insured limits and are not insured in other
     jurisdictions. Management believes that the financial institutions holding
     the Company's investments are financially sound, and, accordingly, minimal
     credit risk exists with respect to these investments. Marketable securities
     are Government of Israel debentures. The Company's trade receivables are
     mainly derived from sales to telecommunication carriers, Internet service
     providers, enterprise network operators, wireless services and cable
     network operators in the United States and Europe. The Company usually does
     not require collateral on trade receivables because its customers are
     large, well-established companies.

     IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board issued SFAS 133,
     "Accounting for Derivative Instruments and Hedging Activities". This
     Statement establishes accounting and reporting standards requiring that
     every derivative instrument (including certain derivative instruments
     embedded in other contracts) be recorded in the balance sheet as either an
     asset or liability measured at its fair value. The Statement also requires
     that changes in the derivative's fair value be recognized currently in
     earnings unless specific hedge accounting criteria are met. Special
     accounting for qualifying hedges allows a derivative's gains and losses to
     offset related results on the hedged item in the income statement and
     requires that a company formally document, designate, and assess the
     effectiveness of transactions that receive hedge accounting. SFAS No. 133
     is effective for fiscal years beginning after June 15, 2000 and cannot be
     applied retroactively. The Company does not expect the impact of this new
     statement on its consolidated balance sheets or results of operations to be
     material.

     In December 1999, the Securities and Exchange Commission issued Staff
     Accounting Bulletin (SAB) 101, "Revenue Recognition in Financial
     Statements" which provides guidance related to revenue recognition based on
     interpretations and practices followed by the SEC. SAB 101 was effective
     the first fiscal quarter of fiscal years beginning after December 15, 1999
     and requires companies to report any changes in revenue recognition as
     cumulative change in accounting principle at the time of implementation in
     accordance with APB 20, "Accounting Changes." In March 2000, the SEC issued
     SAB 101A "Amendment: Revenue Recognition in Financial Statements," which
     delays implementation of SAB 101 until the Company's second fiscal quarter
     of 2000. In June 2000, the SEC issued SAB 101B "Second Amendment: Revenue
     Recognition in Financial Statements," which delays the implementation of
     SAB 101 until the Company's fourth fiscal quarter of 2000. The Company has
     early adopted SAB 101. Such adoption of SAB 101 did not have a material
     effect on the consolidated financial position or results of operations of
     the Company. The Company will adopt the final draft of SAB 101 when
     released.

     In March 2000, the FASB issued Interpretation No. 44 (FIN 44), "Accounting
     for Certain Transactions Involving Stock Compensation - an Interpretation
     of APB 25." This Interpretation clarifies (a) the definition of employee
     for purposes of applying Opinion 25, (b) the criteria for

                                      F-11

     determining whether a plan qualifies as a non compensatory plan, (c) the
     accounting consequence of various modifications to the terms of a
     previously fixed stock option or award, and (d) the accounting for an
     exchange of stock compensation awards in a business combination. This
     Interpretation is effective July 1, 2000, but certain conclusions in this
     Interpretation cover specific events that occur after either December 15,
     1998, or January 12, 2000. To the extent that this Interpretation covers
     events occurring during the period after December 15, 1998, or January 12,
     2000, but before the effective date of July 1, 2000, the effects of
     applying this Interpretation are recognized on a prospective basis from
     July 1, 2000.

     UNAUDITED INFORMATION

     The financial statements include the unaudited consolidated balance sheet
     as of June 30, 2000 and the consolidated statements of operations, changes
     in shareholders equity and cash flows for the six months ended June 30,
     1999 and 2000. This unaudited information has been prepared by the Company
     on the same basis as the audited consolidated financial statements and, in
     management's opinion, reflects all adjustments (consisting only of normal
     recurring accruals) necessary for a fair presentation of the financial
     information, in accordance with generally accepted accounting principles
     for interim financial information, for the periods presented. Results for
     interim periods are not necessarily indicative of the results to be
     expected for the entire year.

5.   ACCRUED SEVERANCE PAY

     The Company's liability for severance pay pursuant to Israeli law is
     calculated based upon the employees' most recent monthly salary multiplied
     by the period of employment. Part of the liability is funded through
     insurance policies which are designated only for severance payments. The
     value of these policies is recorded as an asset in the Company's balance
     sheets.

     Severance expenses for the period from June 8, 1997 (inception) to December
     31, 1997 and for the years ended December 31, 1998 and 1999, were $26, $460
     and $317, respectively.

6.   COMMITMENTS AND CONTINGENT LIABILITIES

     LEASE COMMITMENTS

     The facilities of the Company and its U.S. subsidiary are rented under
     operating leases with terms ending in 2004.

     GUARANTEES

     As of December 31, the Company has provided guarantees, in connection with
     rental agreements totaling approximately $30.

7.   SHARE CAPITAL

     GENERAL

     On January 29, 2000, the Company effected a pro-rata rights offering,
     pursuant to which each existing shareholder was granted six additional
     shares of the same class, with a nominal value of NIS 0.01 par value each,
     subject to the payment or liability for the payment of the nominal value.
     Each option and warrant holder is entitled to adjustments to his or her
     respective options or warrants.

     All share and per share data included in these consolidated financial
     statements have been retroactively adjusted to reflect recapitalizations of
     the Company, the abovementioned rights offering, as well as to reflect the
     1:1 rights offering and 100:1 stock split effected on January 27, 1998 and
     on February 9, 1998, respectively.

     In October 1999, the Company reclassified 5,600,000 ordinary shares into
     Preferred C shares.

     In April 2000 the Company increased its authorized share capital by
     creating an additional 762,000,000 shares of the various classes at a
     nominal value of NIS 0.01. The Company effected a pro-rata three to one
     rights offering and immediately thereafter effected a one share for four
     share consolidation of its shares with the effect of increasing the nominal
     value of each share from NIS 0.01 to NIS 0.04.

         ORDINARY SHARES

         The voting ordinary shares confer upon the holders the right to receive
         notice to participate and vote in the general meetings of the Company,
         the right to receive dividends, if and when declared, and the right to
         appoint directors.

         The non-voting ordinary shares confer all of the rights of the voting
         ordinary shares, except for the rights to appoint directors and to
         receive notice to participate and vote in the general meetings of the
         Company. The non-voting ordinary shares shall be convertible at the
         option of the holder into an equal number of voting ordinary shares.

         PREFERRED SHARES

         The Series A, B-1 and C-1 preferred shares confer all of the rights of
         the voting ordinary shares. The Series B-2 and C-2 non-voting preferred
         shares confer all of the rights of the non-voting ordinary shares. All
         the preferred shares confer additional rights as detailed below:

                  CONVERSION

                  Each share of Series A, B-1 and C-1 preferred shares is
                  convertible into a voting ordinary share on a one-to-one
                  basis, subject to adjustments for future dilution.

                  Each share of Series B-2 and C-2 preferred shares is
                  convertible into Series B-1 and C-1 preferred shares,
                  respectively, on a one-to-one basis, or into non-voting
                  ordinary shares, pursuant to the then applicable conversion
                  rate.

                  All preferred shares shall be automatically converted into
                  ordinary shares at the then applicable conversion rate
                  immediately prior to the consummation of an initial public
                  offering ("IPO").

                  The pro forma shareholders' equity gives effect to the
                  conversion of all outstanding preferred shares as if such
                  conversion occurred on June 30, 2000.

                  LIQUIDATION PREFERENCE

                  The preferred shares confer a preference over ordinary shares,
                  in the event of any liquidation, dissolution or winding up of
                  the Company, either voluntarily or involuntarily. The
                  liquidation preference is equal to the original purchase price
                  in U.S. dollars.

                  OTHER PREFERENCE

                  In addition, all preferred shares confer preemptive rights and
                  certain rights of first refusal, co-sale rights and
                  anti-dilution rights.

          STOCK WARRANTS

          exercisable through the earlier of the termination of a 24-month
          period, an IPO, or liquidation of the Company. As of June 30, 2000,
          642,912 warrants have been exercised.

          STOCK OPTIONS TO SERVICE PROVIDERS

          In June 1997, in connection with an issuance of shares, the Company
          granted its consultants options to purchase 63,700 ordinary shares at
          $0.71 per share in respect of past services. The fair value for these
          options was estimated at the date of grant using an option pricing
          model with the following assumptions: risk-free interest rate of 6%,
          dividend yields of 0%, volatility of 0.1% and an expected life of 1
          year. The fair value of these options at the grant date was
          approximately $0.00. As of June 30, 2000, all the options have been
          exercised.

          In 1998, the Company granted service providers options to purchase
          23,170 ordinary shares at an exercise price of $0.19 in respect of
          past services. As of December 31, 1999, these options are fully
          vested. The Company accounts for these options in accordance with the
          provisions of SFAS No. 123 compensation expense has been recorded in
          the consolidated financial statements regarding those options due to
          the insignificant amount of deferred compensation. The fair value for
          these options was estimated at the date of grant using an option
          pricing model with the following assumptions: risk-free interest rate
          of 5.5% dividend yields of 0% volatility of 0.1% and an expected life
          of 1 year. The fair value of these options at the grant date was
          approximately $0.00. As of June 30, 2000, 5,250 options have been
          exercised.

          STOCK OPTIONS

          As of December 31, 1999, the Company has authorized, through several
          share option plans, the grant of options to officers, management, key
          employees and others of up to 3,302,236 of the Company's ordinary
          shares. The options granted generally become fully exercisable after
          four years of employment and expire eight years from the approval date
          of the option plan under the terms they were granted.

          Deferred compensation represents the excess of the market value over
          the exercise price. Deferred compensation totaled $3,205 for 1999.
          Deferred compensation is amortized to the statements of operations
          over the vesting period of four years.

          Under SFAS No. 123, pro forma information regarding net loss and net
          loss per share is required and has been determined as if the Company
          had accounted for its employee stock option under the fair value
          method of that Statement. The fair value for these options was
          estimated at the date of grant using a minimum value option pricing
          model with the following assumptions for 1998 and 1999: risk-free
          interest rates of 6.00% and 5.75%, respectively, dividend yields of 0%
          and an expected life of the option range between 1.5 to 4.5 years.

     will be paid in NIS. The Company does not intend to pay cash dividends in
     the foreseeable future.

8.   INCOME TAXES

     TAX BENEFITS UNDER ISRAEL'S LAW FOR THE ENCOURAGEMENT OF CAPITAL
     INVESTMENTS, 1959 ("THE LAW")

     The Company has been granted the status of "Approved Enterprise" under the
     Law in 1998.

     According to the provisions of the Law, the Company has elected the
     "alternative benefits" - waiver of grants in return for a tax exemption
     and, accordingly, the Company's income in Israel is tax-exempt for a period
     of two years commencing with the year it first earns taxable income
     relating to each expansion program, and subject to corporate taxes at the
     reduced rate of 10% to 25% (depending on the level of non-Israel
     investments in the Company), for an additional period of eight years.

     As the Company currently has no taxable income, these benefits have not yet
     commenced.

     The tax-exempt profits that will be earned by the Company's "Approved
     Enterprise" can be distributed to shareholders, without imposing a tax
     liability to the Company only upon the complete liquidation of the Company.
     If these retained tax-exempt profits are distributed in a manner other than
     in the complete liquidation of the Company, they would be taxed at the
     corporate tax rate applicable to such profits as if the Company had not
     elected the alternative system of benefits. The Company's board of
     directors has determined that such tax exempt income will not be
     distributed as dividends.

     The period of tax benefits, detailed above, is limited to the earlier of 12
     years from the commencement of production, or 14 years from the approval
     date. Accordingly, the period relating to the Company's approved enterprise
     will expire in 2012.

     Should the Company derive income in Israel from sources other than the
     approved enterprise during the relevant period of benefits, such income
     will be taxable at regular corporate tax rate of 36%.

     MEASUREMENT OF RESULTS FOR TAX PURPOSES

     Results for tax purposes are measured and reflected in real terms in
     accordance with the changes in the Israeli CPI. As explained in Note 2, the
     consolidated financial statements are presented in U.S. dollars. The
     difference between the change in the Israeli CPI and in the NIS/U.S. dollar
     exchange rate causes a difference between taxable income or loss and the
     income or loss before taxes reflected in the consolidated financial
     statements. In accordance with paragraph 9(f) of SFAS No. 109, the Company
     has not provided deferred income taxes on this difference between the
     reporting currency and the tax bases of assets and liabilities.

     TAX BENEFITS UNDER ISRAEL'S LAW FOR THE ENCOURAGEMENT OF INDUSTRY
     (TAXATION), 1969

     The Company is an "industrial company" under the above law and as such is
     entitled to certain tax benefits, including accelerated rates of
     depreciation on certain assets and deduction of expenses incurred in
     respect of public issuance of securities and deduction of 12.5% per annum
     of the cost of certain intangible property rights. The Company has not
     utilized these tax benefits.

     NET OPERATING LOSS CARRYFORWARDS

     As of December 31, 1999, the Company had approximately $4,700 of Israeli
     net operating loss carryforwards. The Israeli loss carryforwards have no
     expiration date. The Company expects that during the period these tax
     losses are utilized, its income would be substantially tax exempt.

     Accordingly, there will be no tax benefit available from such losses and no
     deferred income taxes have been included in these consolidated financial
     statements.

     As of December 31, 1999, the U.S. subsidiary had U.S. federal and state net
     operating loss carryforwards for income tax purposes in the amount of
     approximately $6,900, which can be carried forward and offset against
     taxable income in various amounts between the years 2006 and 2019.

     Utilization of U.S. net operating losses may be subject to substantial
     annual limitation due to the "change in ownership" provisions of the
     Internal Revenue Code of 1986 and similar state provisions. The annual
     limitation may result in the expiration of net operating losses before
     utilization.

     DEFERRED 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 and liabilities
     are as follows:

     The Company's U.S subsidiary has provided valuation allowances in respect
     of deferred tax assets resulting from tax loss carryforwards. Management
     currently believes that since the Company has a history of losses it is
     more likely than not that the deferred tax regarding the loss carryforwards
     and other temporary differences will not be realized in the foreseeable
     future.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

       The Companies Law provides that an Israeli company cannot exonerate an
office holder from liability with respect to a breach of his or her duty of
loyalty, but may exonerate in advance an office holder from his or her liability
to the company, in whole or in part, with respect to a breach of his or her duty
of care. Our articles of association provide that, subject to any restrictions
imposed by the Companies Law, we may enter into an insurance contract providing
coverage for the liability of any of our office holders with respect to:

       o   a breach of his or her duty of care to us or to another person;

       o   a breach of his or her duty of loyalty to us, provided that the
           office holder acted in good faith and had reasonable grounds to
           assume that his or her act would not prejudice our interests; or

       o   a financial liability imposed upon him or her in favor of another
           person with respect to an act performed by him or her in his or her
           capacity as an office holder.

       In addition, we may indemnify an office holder against the following
expenses or liabilities imposed upon him or her in his or her capacity as an
office holder:

       o   a financial liability imposed on him or her in favor of another
           person by any judgment, including a settlement or an arbitrator's
           award approved by a court; and

       o   reasonable litigation expenses, including attorneys' fees, incurred
           by such office holder or imposed upon him or her by a court, in
           relation to proceedings instigated by us against him or her or that
           are instigated on our behalf or by another person, or as a result of
           a criminal charge from which he or she was acquitted, or a criminal
           charge in which he or she was convicted for a criminal offense that
           does not require proof of intent.

       The Companies Law provides that a company may not indemnify an office
holder nor enter into an insurance contract which would provide coverage for any
monetary liability incurred as a result of any of the following:

       o   a breach by the officer holder of his or her duty of loyalty unless
           the office holder acted in good faith and had a reasonable basis to
           believe that the act would not prejudice the company;

                                      II-1
<PAGE>

       o   a breach by the office holder of his or her duty of care if such
           breach was committed intentionally or recklessly;

       o   an act or omission with the intent to unlawfully derive a personal
           benefit; or

       o   a fine levied against the office holder as a result of a criminal
           offense.

       Under the Companies Law, the shareholders of a company may amend its
articles of association to include either of the following provisions:

       o   a provision authorizing the company to grant in advance an
           undertaking to indemnify an office holder, provided that the
           undertaking is limited to specified classes of events which the board
           of directors deem foreseeable at the time of grant and limited to an
           amount determined by the board of directors to be reasonable under
           the circumstances, or

       o   a provision authorizing the company to retroactively indemnify an
           office holder.

       In addition, pursuant to the Companies Law, indemnification of, and
procurement of insurance coverage for, a company's office holders must be
approved by the audit committee and the board of directors. In the case of
directors, additional approval by the shareholders is required.

       Our articles of association allow for us to insure and indemnify office
holders to the fullest extent permitted by Israeli law, provided that the
insurance or indemnification is approved by the audit committee of our board of
directors and, if required by the Companies Law, also by our shareholders.

ITEM 17. UNDERTAKINGS.

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

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

       The undersigned Registrant hereby undertakes that:

       (1) For purposes of determining any liability under the Securities Act of
1933, as amended, the information omitted from the form of prospectus filed as
part of this registration statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
registration statement as of the time it was declared effective.

       (2) For the purpose of determining any liability under the Securities Act
of 1933, as amended, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial BONA FIDE offering thereof.
