     You should read the following summary together with the more detailed
information regarding our company and the ordinary shares being sold in this
offering and our consolidated financial statements and the related notes
appearing elsewhere in this prospectus.

                                      XACCT

     We are a leading provider of intelligent business infrastructure software
for telecommunications carriers, Internet service providers, enterprise network
operators and cable network operators, which we refer to collectively as network
service providers. Our infrastructure platform allows network service providers
to leverage the rapid growth of Internet services and data traffic to increase
revenue opportunities. This foundation technology provides a single point of
interface between the operations and business support systems of network service
providers and the physical network. Network service providers use our platform's
comprehensive real-time data collection, data aggregation and automated user
account provisioning capabilities to deploy new business models and
higher-margin, enhanced services. As of December 31, 1999, we had licensed our
business software to over 20 network service providers. Our customers include
Bell Nexxia, Global One, GTE Internetworking, Harvard University, Mannesman
Ipulsys, MCI Worldcom, Siemens, TV Cabo, Verio and UUNET. In addition, we have
developed strategic alliances or collaborative relationships with a group of
over 70 system integrators, value-added resellers, network infrastructure
vendors and software applications vendors.

     As the volume of global Internet traffic has grown and demand for high
value-added, Internet-based services has increased, network service providers
have found that their inability to capture, aggregate and transform the raw data
carried over their networks into meaningful business information has constrained
their revenue generation potential. Network service providers are actively
seeking ways to offer higher-margin, enhanced services, which require a flexible
and scalable software platform that dynamically monitors, aggregates, provisions
and configures multiple service-types across their networks. 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 platform enables network service providers to support flexible,
sophisticated business models with differentiated pricing and services. Our
business infrastructure platform collects and synthesizes a high volume of
network usage data from multiple sources and all layers of the network. Network
service providers can use this real-time data to offer and charge appropriately
for service level agreements or for services based on quality of service,
transactions, events, content or volume. This detailed network information can
also be used to support customer relationship management, customer retention and
fraud management applications. In addition, our platform provides for automated
user account provisioning 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 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 requirements of network service providers. Our software
platform's distributed architecture is designed to support carrier-class network
service providers. By deploying software modules throughout the network, our
distributed software architecture captures usage information from all layers of
the network and scales with the growth of our customers' networks and network
traffic while maintaining data integrity and high system availability. 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.

                                        4



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

     -    Enhancing our product line and extending our technology leadership;

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

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

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

     -    Delivering our solution in strategically targeted international
          markets.

                                  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. Until 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 limited 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 and $9.1
million for 1999. As of December 31, 1999, we had an accumulated deficit of
$14.2 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 product line
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 and consequently may 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:

     -    variations in demand for the XACCTUSAGE platform and related products
          and services;

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

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

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

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


                                       8


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

     -    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

     -    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 AND
RELATED PRODUCTS AND 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, and specifically
the last week of that quarter. We expect this trend to continue and intensify.
Since our operating expenses are based on anticipated revenues 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 OUR SALES AND IMPLEMENTATION CYCLES FOR OUR PRODUCTS ARE 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 environment and the quantity of the hardware and the degree
of hardware configuration necessary to deploy our


                                       9



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.

     A relatively small number of customers account for a significant portion of
our total revenues. In 1999, sales to our ten largest customers accounted for
83.6% of our revenues. In 1999, sales to TV Cabo, UUNET, GTE Internetworkings
and Verio accounted for 51.4% 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
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 software license revenues in each quarter from a
small number of relatively large customer orders. For example, in each of the
four quarters in the period ended December 31, 1999, we had at least one
customer that accounted for at least 17.5% 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 agreements 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. 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 business infrastructure platform 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 business infrastructure solutions or decrease their
spending on business 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 to meet the expanding requirements of network service providers,
we will be unable to increase or sustain our revenues.



                                       10


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 deployment 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:

     -    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;

     -    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;

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

     -    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 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. 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.


                                       11



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:

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

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

     -    failure to achieve market acceptance;

     -    diversion of development resources;

     -    negative publicity and injury to our reputation;

     -    increased service and warranty costs;

     -    legal actions by customers against us; and

     -    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


                                       12



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. 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. 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. 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, and are becoming a larger
component of our revenues. Service revenues constituted 25% of our revenues in
1999. 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. Customer service,
support and maintenance 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


                                       13


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:

     -    in our corporate name;

     -    as part of the services we offer; and

     -    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 40 at December
31, 1997 to 94 at December 31, 1999. In particular, our sales force grew from
one person at December 31, 1997 to 22 people at December 31, 1999. For us to
effectively manage our growth, we must continue to do the following:

     -    improve our operational, financial and management controls;

     -    improve our reporting systems and procedures;

     -    install new management and information control systems; and

     -    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
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.


                                       14


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.

     Although we have not done so in the past, 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.

                          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 COULD BE PREVENTED FROM SELLING OR DEVELOPING OUR PRODUCTS IF THE GNU GENERAL
PUBLIC LICENSE AND SIMILAR LICENSES UNDER WHICH SOME OF THE SOFTWARE
INCORPORATED INTO OUR PRODUCTS IS DEVELOPED AND LICENSED, ARE NOT ENFORCEABLE,
OR ARE NOT EFFECTIVELY ENFORCED.

     Some of the software incorporated into our products has been developed and
licensed under the GNU General Public License, and similar open source licenses.
These licenses require that any software program licensed under


                                       15



them may be copied, used, modified and distributed freely, so long as all
modifications are also freely made available and licensed under the same
conditions. We know of no instance in which a party has challenged the validity
of these licenses or in which these licenses have been interpreted in a legal
proceeding. To date, all compliance with these licenses has been voluntary. It
is possible that a court would hold one or more of these licenses to be
unenforceable in the event that someone were to file a claim asserting
proprietary rights in a program developed and distributed under them. Any ruling
by a court that these licenses are not enforceable, or that the software
incorporated into our products or significant portions of the software may not
be copied, modified or distributed freely, would have the effect of preventing
us from selling or developing our products, unless we are able to negotiate a
license for the use of the software or replace the affected portions.

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:

     -    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;

     -    companies with products that address our market, such as Hewlett
          Packard, Lucent, EHPT and Narus; and

     -    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 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.


                                       16


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:

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

     -    we cease to do business without a successor; or

     -    we do not provide contractually agreed maintenance and support.

     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


                                       17


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 15,394,526 ordinary shares, which will represent approximately
                  % 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 that 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:

     -    variations in our quarterly operating results;

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

     -    changes in market valuations of similar companies;

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

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

     -    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.


                                       18



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
                      % 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:

     -    develop or enhance our products and services;

     -    acquire new technologies, products or businesses;

     -    expand operations, in the United States or internationally;

     -    hire, train and retain employees; or

     -    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.

WE MAY APPLY THE PROCEEDS OF THIS OFFERING TO USES THAT DO NOT INCREASE OUR
OPERATING RESULTS OR 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 increase our
operating results or 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 $
in net tangible book value per share of


                                       19



ordinary shares from the price you paid, based on an assumed initial public
offering price of $                     per share. The exercise of outstanding
options and warrants 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 from sales outside North America. As
a result, we face additional risks from doing business internationally
including:

     -    reduced protection of intellectual property rights in some countries;

     -    licenses, tariffs and other trade barriers;

     -    difficulties in staffing and managing foreign operations;

     -    longer sales and payment cycles;

     -    greater difficulties in collecting accounts receivable;

     -    seasonal reductions in business activity;

     -    potentially adverse tax consequences;

     -    laws and business practices favoring local competition;

     -    costs and difficulties of customizing products for foreign countries;

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

     -    political and economic instability; and

     -    variance and unexpected changes in local laws and regulations.

     Our 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 years, 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 48 are currently or may be obligated to
perform annual reserve duty in the Israeli Defense Forces and are subject to
being


                                       20


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

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 programs 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.

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.

     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:

     -    the judgment was obtained by fraud;

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

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

     -    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

     -    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

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.

                                 USE OF PROCEEDS

       We estimate that the net proceeds from the sale of the
                          ordinary shares that we are selling in this offering,
after deducting estimated underwriting discounts and estimated offering expenses
payable by us, will be approximately $                   at an assumed initial
public offering price of $                    per share.

     We intend to use the net proceeds to finance the growth of our business
through the expansion of sales, marketing and distribution activities and
increased research and development activities with respect to enhancements to
existing products and new products, and for working capital and general
corporate purposes. We may use a portion of the proceeds of this offering to
acquire new businesses, products or technologies that may be complementary to
our current or future business. We do not currently have any specific plan or
program with respect to any such acquisitions. Pending use of the net proceeds
of this offering, we intend to invest the net proceeds in interest-bearing,
investment-grade securities.


                                 DIVIDEND POLICY

       We have not declared or paid any cash dividends on our ordinary shares in
the past. We do not expect to pay 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 Shekels, 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, these payments. Because exchange rates between the NIS and the
U.S. dollar fluctuate, a United States 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.

                                 CAPITALIZATION

     The following table sets forth our capitalization as of December 31, 1999:

     -    on an actual basis;

     -    on a pro forma basis giving effect to (1) the receipt of net proceeds
          of approximately $14.3 million from the sale of 1,227,235 preferred
          shares in March 2000, (2) the exercise of warrants outstanding as of
          December 31, 1999 to purchase 2,058,371 preferred shares at a weighted
          average exercise price of $6.19 per share, which warrants if
          unexercised would expire upon the closing of this offering and (3) the
          conversion of all issued and outstanding preferred shares into
          ordinary shares; and

     -    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
          $                      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
December 31, 1999 was $44.7 million, or $2.13 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 giving effect to the sale of 1,227,235 preferred shares for aggregate net
proceeds of $14.3 million in March 2000, and assuming the exercise of warrants
to purchase 2,058,371 preferred shares outstanding as of December 31, 1999,
which warrants if unexercised would expire upon the completion of this offering.
Assuming our sale of ordinary shares offered by this prospectus at an assumed
initial public offering price of $ 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 December 31, 1999 would
have been $ , or $ per ordinary share. This represents an immediate increase in
pro forma net tangible book value of $ per share to existing shareholders and an
immediate dilution of $ per share to new investors purchasing ordinary shares in
this offering. The following table illustrates this dilution on a per ordinary
share basis:

     The following table sets forth on a pro forma as adjusted basis, as of
December 31, 1999, the differences between the number of ordinary shares
purchased from us, the total consideration paid and the average price per share
paid by existing holders of ordinary shares and by the new investors, before
deducting the estimated underwriting discount and estimated offering expenses
payable by us.

     The foregoing discussion and tables assume no exercise of options
outstanding as of December 31, 1999 to purchase 3,113,439 ordinary shares at a
weighted average exercise price of $0.68 per share and assumes no exercise of
warrants outstanding to purchase 29,050 ordinary shares at a weighted average
exercise price of $0.30 per share, which warrants do not expire upon the
completion of this offering. To the extent these options and warrants are
exercised, 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              , or     % of the
total ordinary shares outstanding after this offering.

                     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 leading provider of intelligent business infrastructure software
for network service providers. Our infrastructure platform allows network
service providers to implement new value- and usage-based business models and to
offer higher-margin, enhanced services through comprehensive real-time data
collection, data aggregation and automated user account provisioning. The XACCT
platform is a foundation technology that provides a single point of interface
between the operations and business support systems of network service providers
and the physical network. 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. At December 31, 1999, we had an accumulated deficit
of $14.2 million.

       We derive our revenues principally from software licenses and related
services. Customer payments received prior to the recognition of revenues are
recorded as deferred revenue. To date, our license revenues have been derived
from licenses of XACCTUSAGE, our server-based software platform that resides at
the network service provider site, as well as information source modules and
gatherers which reside near the switches, routers, hubs and other elements of
the network. In each case, we record license revenue when a software license
agreement has been executed or a definitive purchase order has been received and
the product has been delivered to the end customers, no significant obligations
with regard to implementation remain, the fee is fixed and determinable and
collectibility is probable.

       Service revenues include product maintenance and support, consulting and
training. Customers who license our products usually purchase maintenance
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 ratably 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 revenues are deferred and
recognized when provided to the customer. Customer advances and billed amounts
due from customers in excess of recognized revenues are recorded as deferred
revenues.

     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 revenues from customers
located in North America and approximately 37% of our revenues from customers
outside North America, substantially all of which was in Europe. In the first
quarter 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, UUNET, GTE Internetworking and Verio each accounted
for at least 10% of total revenues in 1999.

       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 recorded deferred stock compensation of $3.2
million in connection with stock options we have granted. This amount is
amortized over the four year vesting period of the options using the multiple
option approach. Based on options granted through December 31, 1999, we expect
to record stock-based compensation expense of $356,000 in the quarter ending
March 31, 2000. We expect that stock-based compensation expense recorded in
quarters after March 31, 2000 will decrease sequentially. We anticipate this
expense to decrease consistently in future periods. Unearned 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 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

FOUR QUARTERS ENDED DECEMBER 31, 1999

       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 four quarters ended December 31, 1999. The following
table lists the operating results for the four most recent quarters as well as,
for the periods indicated, each line item as a percentage of total revenues:

     REVENUES

     Total revenues increased sequentially on a quarterly basis from $85,000 for
the quarter ended March 31, 1999 to $578,000 for the quarter ended December 31,
1999. 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 in 1999 as our customer base and our average transaction size
increased. Our customer base increased from three at March 31, 1999 to 25 at
December 31, 1999. Average transaction size increased from approximately
$22,000 in the quarter ended March 31, 1999 to approximately $110,000 in the
quarter ended December 31, 1999 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 31, 1999 to $379,000 for the quarter ended
December 31, 1999.

     SERVICE. Service revenues increased from $4,000 for the quarter ended March
31, 1999 to $199,000 for the quarter ended December 31, 1999. This increase
resulted primarily from increased software licenses following the introduction
of our products and the expansion of our professional service organization. The
increase in service revenues in the quarter ended December 31, 1999 was
primarily due to approximately $140,000 in fees generated from the custom
development and implementation activities performed for a large customer. We
anticipate that service revenue will decline as a percentage of total revenue in
the short term.

     COST OF REVENUES

     Total cost of revenues increased sequentially on a quarterly basis from
$22,000 for the quarter ended March 31, 1999 to $98,000 for the quarter ended
December 31, 1999.

     LICENSE. Cost of license revenues consists of product and documentation
production costs, packaging and shipping and third-party software license
payments. 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 consists of salaries and related payroll
and facility expenses for service, support and training personnel. Cost of
service revenues increased sequentially on a quarterly basis during 1999. This
increase was due primarily to our hiring of additional service personnel in 1999
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


                                       30


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 include
salaries and related payroll and facilities expenses for engineering and
technical personnel, as well as the cost of third party development consultants.
We expense all of these costs as incurred. A significant majority of our
research and development personnel are located in Israel. Research and
development expenses increased from $509,000 for the quarter ended September 30,
1999 to $708,000 for the quarter ended December 31, 1999 due primarily to the
hiring of seven additional engineering personnel during the quarter ended
December 31, 1999. 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 consist of salaries,
commissions and related overhead expenses for sales and marketing personnel, as
well as advertising, promotional and travel expenses. Sales and marketing
expenses increased from $1.1 million for the quarter ended March 31, 1999 to
$2.4 million for the quarter ended December 31, 1999 due primarily to increased
commissions and our hiring of additional sales and marketing personnel. We
increased our sales and marketing department from 12 employees at December 31,
1998 to 48 employees at December 31, 1999. We anticipate that sales and
marketing expenses will increase significantly in dollar amounts as we continue
to expand our sales and marketing organization.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist of
salaries for administrative, executive and finance personnel and related
overhead expenses, recruiting costs and professional service fees. General and
administrative expenses increased from $194,000 in the quarter ended March 31,
1999 to $518,000 in the quarter ended December 31, 1999. This sequential
increase was primarily attributable to 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 employee
stock-based compensation expense of $381,000 in 1999.

     INTEREST AND OTHER INCOME, NET. Interest and other income, net consists
primarily of interest received on invested cash balances. Interest and other
income, net increased from $8,000 in the quarter ended September 30, 1999 to
$146,000 in the quarter ended December 31, 1999 due primarily to higher cash
balances in the fourth quarter following an equity financing completed in
October 1999.

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.

     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 of 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.


                                       31


     OPERATING EXPENSES

     RESEARCH AND DEVELOPMENT. Research and development expenses increased 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 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 were $1.2
million in 1999.

     AMORTIZATION OF DEFERRED STOCK COMPENSATION. We recorded no deferred
stock-based compensation in the period from our inception to December 31, 1998.
We recorded $3.2 million in deferred stock-based 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
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.

LIQUIDITY AND CAPITAL RESOURCES

     Since our inception, we have financed our operations primarily through the
private sale of $32.3 million of our securities. We anticipate that we will
receive $12.7 million on or prior to the closing of this offering from the
exercise of outstanding warrants for the purchase of 2,058,371 ordinary shares
at a weighted average exercise price of $6.19 per share, which warrants expire
upon the completion of this public offering.

     Net cash used in operating activities was $4.2 million in the period from
our inception through December 31, 1998 and $8.2 million in 1999 and was
primarily attributable to net losses during these periods.

     Net cash used in investing activities was $437,000 in the period from our
inception through December 31, 1998 and $1.5 million in 1999. Net cash used in
investing activities consists primarily of purchases of computer hardware and
software, office furniture and equipment and, in 1999, investment in short-term
term bank deposits.

     Net cash provided by financing activities was $10.1 million in the period
from inception through December 31, 1998 and $21.6 million in 1999. Net cash
provided by financing activities consists primarily of net proceeds from the
issuance of preferred shares.

     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 and 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


                                       32



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. Accordingly, the period relating to this
approved enterprise will expire in 2012.

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

INFLATION AND MARKET RISK

     Most of our sales traditionally 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 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 leading provider of intelligent business infrastructure software
for next-generation networks. The XACCT platform is a foundation technology that
provides a single point of interface between the operations and business support
systems of network service providers and the physical network. Our software
platform allows network service providers to implement new value- and
usage-based business models and to offer higher-margin, enhanced services
through comprehensive real-time data collection, data aggregation and automated
user account provisioning. 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
December 31, 1999, we had over 20 network service providers customers. Our
customers include Bell Nexxia, Global One, GTE Internetworking, Harvard
University, Mannesman Ipulsys, MCI Worldcom, Siemens, TV Cabo, Verio and UUNET.
In addition, we have developed strategic alliances or collaborative
relationships with a group of over 70 system integrators, value-added resellers,
network infrastructure vendors and software applications vendors.

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 159 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 TV operators, enterprise network operators
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 high value-added
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 the raw data carried over their
networks 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 flexible, sophisticated business
models based on value to the user and cost to the network service provider.
These new business models will increase revenues by enabling flexible service
offerings, 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-based pricing of services and price modeling;

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


                                       34



       o   intelligent analysis of real-time network usage data;

       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
intelligent 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 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 leading provider of business infrastructure software for the
next-generation public network. Our intelligent business infrastructure platform
allows network service providers to implement new value- and usage-based
business models and offer higher-margin, enhanced services. The XACCT platform
is a foundation technology that provides a single point of interface between
Internet back office operations and business support systems and the physical
network. Network service providers utilize our platform to run mission-critical
business applications that require comprehensive real-time data collection, data
aggregation and automated user account provisioning. We have designed our
solution to provide the carrier-class scalability, reliability, manageability
and flexibility that our customers demand.

       The following diagram illustrates the interface that the XACCT platform
provides between the operations and business support systems of network service
providers and the physical network:

                [DIAGRAM OF OUR BUSINESS INFRASTRUCTURE PLATFORM]


                                       35



       Our solution offers our customers the following benefits:

       ENABLES INTELLIGENT PRICING OF VALUE-ADDED SERVICES. Our business
infrastructure system captures, aggregates and analyzes in real-time the data
necessary to allow network service providers to price their services based on
value to the user and cost to the network service provider. For example, instead
of charging a flat-rate fee for simple connectivity, network service providers
can use our solution to offer and charge appropriately for service level
agreements or for services based on quality of service, transactions, events,
content, or volume. Our solution also provides detailed network information that
can be used to support customer relationship management, customer retention and
fraud management applications.

       ENABLES AUTOMATED USER ACCOUNT PROVISIONING. Our platform is designed to
allow network service providers to implement automated user account
provisioning, including self-provisioning, meaning that the network service
provider's users can activate, modify or deactivate services without the
intervention of the network service provider. Automated user account
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. Internet-based services
generate significant amounts of data that must be aggregated, correlated,
processed and analyzed in real-time. We have designed our solution with a
distributed software architecture designed to scale with the growth of our
customers' networks and the growth of network traffic. This distributed
architecture helps ensure data integrity and high system availability by placing
intelligent software agents throughout the network, enabling redundant data
collection and transmission to multiple data repositories.

       FLEXIBILITY AND EXTENSIBILITY. 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 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
user account 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 70 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


                                       36



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

       XACCTUSAGE is a carrier-class software platform that provides two basic
functions: network usage data collection and automated user account
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.

       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 user account 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.

       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. It utilizes a variety of device-specific, as
well as general purpose, software agents called information source modules, or
ISMs. 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, or
LDAP, servers, domain name servers, or DNS, web servers, email servers, video
servers, voice over IP gateways and hundreds of other network elements. Because
they are located near these network elements, our ISMs 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.

       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


                                       37



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.

       USER ACCOUNT PROVISIONING. The automated, end-to-end user account
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 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.

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

       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.

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 December 31, 1999, over 20
customers had licensed XACCTUSAGE, including the following:

         Bell Nexxia (Canada)                MCI Worldcom (U.S.)
         Global One (U.S. and Belgium)       Siemens (Canada)
         GTE Internetworking (U.S.)          TV Cabo (Portugal)
         Harvard University (U.S.)           Verio (U.S.)
         Mannesman Ipulsys (Europe)          UUNET (U.S.)

       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. The seamless integration of XACCTUSAGE with
       Broadwing's existing Kenan billing system enables Broadwing to offer new
       services quickly and with minimal disruption.

       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 by customer 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.

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 December 31, 1999, our sales force consisted of 22
sales professionals and 21 technical field professionals. We have sales offices
in the greater metropolitan areas of Atlanta, Denver, San Francisco, Tel

                                       39



Aviv, 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.

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 December 31, 1999:

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 21 employees as of December 31, 1999.

RESEARCH AND DEVELOPMENT

       As of December 31, 1999, our engineering group consisted of 31 employees,
divided into the following groups:

       CORE RESEARCH AND DEVELOPMENT. This group researches and develops
advanced architectures and technologies and works to improve the performance,
quality, features, coverage and manageability of the XACCTUSAGE product and
related information source modules. This group also closely monitors
developments in industry standards related to eBusiness, Internet technologies,
operating systems, networks and software applications.

       APPLICATIONS. This group develops back office applications that, when
combined with XACCTUSAGE, will provide a vertically integrated solution for
select back office functions.

       TECHNICAL PUBLICATIONS. This group is responsible for the technical
writing for our products.

       QUALITY ASSURANCE. This group designs and manages a process designed to
identify and prevent software defects 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


                                       41


$390,000 in the period from our inception in June 1997 through December 31,
1997, $1.5 million in 1998 and $2.2 million in 1999.

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, Lucent, EHPT and Narus; 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.

       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.

                                       42


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 license agreements that
impose restrictions on 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.

       Some of our license agreements require us to place the source code for
XACCTUSAGE into escrow. These agreements generally provide that these parties
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.

       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.

EMPLOYEES

       As of December 31, 1999, we had a total of 92 full time employees. Of the
total number of employees, 31 were engaged in research and development, 22 in
sales, seven in marketing, 21 in customer support, professional services and
training, and 11 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 December 31, 1999, 47 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
most of our ongoing severance obligations for our Israeli employees by making
monthly payments for insurance policies to cover these obligations.

FACILITIES

     We lease approximately 8,100 square feet in a single office building
located in Bnei-Brak, Israel and approximately 16,200 square feet in a single
office building located in Santa Clara, California. The leases for the office
space in Bnei-Brak, Israel expire in April 2000. We have entered into a lease
for office space in Ramat Gan,


                                       43


Israel for approximately 18,300 square feet commencing April 2000 that will
expire in April 2003 with an option for an additional three years. The lease for
the office space in Santa Clara, California expires in December 2004.

LEGAL PROCEEDINGS

       We are not a party to any material legal proceedings.


                                       44

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. As of August 2000, 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.

     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
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.

                                       46



     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 effective date for
appointment of outside directors for a foreign company has been postponed until
August 1, 2000, and 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. Within the statutory period as provided
for in the Companies Law and the regulations, we intend to take all actions
necessary to comply with the Companies Law and its requirements relating to the
appointment of outside directors.

                                       47



     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 such as our
company to appoint an audit committee. Our audit committee was formed in
November 1998 and is currently comprised of Messrs. Reynolds, Springer and
Yanovski. 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. The audit committee of our
board of directors 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.

     INTERNAL AUDITOR

     Under the Companies Law, the board of directors must appoint an internal
auditor, nominated 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 office holder, or an
affiliate, or a relative of an 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.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The compensation committee is currently comprised of Messrs. Hawk, Springer
and Yanovski. None of these committee members has at any time been an officer or
employee of our company. 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 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

                                       48



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 shares at an exercise
price of $0.35 per share. Mr. Hawk purchased 24,500 ordinary shares upon
exercise of this option in August 1999 at an aggregate exercise price of $8,575.
These ordinary shares vest over a four year period and are subject to repurchase
until vested.

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 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. The exercise price per share
was equal to the fair market value of the ordinary shares on the date of grant
as determined by our board of directors. Percentage of total options is based on
an aggregate of 1,461,670 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 potential
realizable value is calculated based on the term of the eight-year option and
assumed rates of share appreciation of 5% and 10%, compounded annually. These
assumed rates comply with the rules of the Securities and Exchange Commission
and do not represent our estimate of future share price. Actual gains, if any,
on share option exercises will be dependent on the future performance of our
ordinary shares.

EMPLOYEE BENEFIT PLANS

     SECTION 102 SHARE OPTION PLAN

     In July 1998, our board of directors adopted a share option plan in
accordance with Section 102 of the Israeli Income Tax Ordinance, or the 102
Plan. The 102 Plan expires in 2006. As of February 29, 2000, we had outstanding
options to purchase 803,600 ordinary shares under the 102 Plan at a weighted
average exercise price of $0.77 per ordinary share. As of that date, our
officers held options to purchase 192,724 ordinary shares under the 102 Plan,
and no director held any options issued under the 102 Plan. We believe that our
issuance of options to Israeli employees has been done in compliance with
Israeli securities laws. However, due to uncertainty relating to the proper
interpretation of these laws, we cannot be certain the Israel Securities
Authority will not challenge our position.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE SECTION 102 SHARE OPTION
PLAN. Under the 102 Plan, we have reserved an aggregate of 2,060,000 voting
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 102 Plan at the time of the grant.
The options granted under the 102 Plan typically expire no later than


                                       52



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 102 Plan. The administrator has the power to determine
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 102 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
102 Plan does not allow for the transfer of options and only the optionee may
exercise an option.

     ADJUSTMENTS UPON MERGER. The 102 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 102 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 February 29, 2000, we had issued an aggregate of 459,214
options that will be taxed in accordance with Section 3(i) of the Israeli Income
Tax Ordinance. Prior to the completion of this offering, we intend to adopt a
formal, written share option plan in accordance with Section 3(i) of the Israeli
Income Tax Ordinance, or the 3(i) Plan. The 3(i) Plan will be effective for a
period of ten years commencing upon the date of its adoption.

     NUMBER OF ORDINARY SHARES AVAILABLE UNDER THE SECTION 3(i) SHARE OPTION
PLAN. Under the 3(i) Plan, our board of directors has authority to grant options
to purchase ordinary shares to our Israeli employees, subject to shareholder
approval upon reaching specified thresholds. Any shares subject to options that
are cancelled or not exercised before expiration become available for future
grant.

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

     RIGHTS UPON TERMINATION. The 3(i) Plan will provide 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 12
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.


                                       53



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

     ADJUSTMENTS UPON MERGER OR ASSET SALE. The 3(i) Plan will provide 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 will be exercisable or
available for sale immediately upon vesting and are not required to be deposited
in trust. The participants in the 3(i) Plan are not eligible for any tax
benefits or deferrals. 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 related income tax or capital gain tax shall
be paid by the participants.

     1998 SHARE OPTION PLAN

     Our board of directors adopted the 1998 Share Option Plan in July 1998. Our
1998 Share Option Plan provides for the grant of incentive share options, within

for the grant of nonstatutory share options to our employees, directors and
consultants.

share were issued and outstanding, 317,232 ordinary shares had been issued upon
exercise of outstanding options and 1,959,066 ordinary shares remain available
for issuance.

     ADMINISTRATION OF THE 1998 SHARE OPTION PLAN. In general, our board of
directors or a committee maintained by our board for such purpose administers
the 1998 Share Option Plan. The administrator has the power to determine 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. The administrator determines the
exercise price of options granted under the 1998 Share 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.

     LIMITATION ON OPTION GRANTS. 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 12 months. In all other
cases, the option will generally remain exercisable for 3 months. An option may
generally not be exercised later than the expiration of its original term.

her lifetime.

     AMENDMENT AND TERMINATION OF OUR 1998 SHARE OPTION PLAN. Our 1998 Share
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 Share Option Plan, provided it does not adversely
affect any previously granted option.

subsidiary for at least 20 hours per week and more than five months in any

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;


                                       56


     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.
Arrangements regarding compensation and terms of service of directors, and
directors who are also managers of the company, require the approval by the
audit committee, 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 votes by proxy 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.


                                       57


     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.

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
shall 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

     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.


                                       58


     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.

     The options listed above generally vest over a four year period. On August
1, 1999, Mr. Hawk exercised his option to purchase 24,500 ordinary shares for an

the Company until vested.

     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 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.

                          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 December 31, 1999, our authorized share capital consisted of
37,630,000 voting ordinary shares, NIS 0.01 nominal value per share, 1,820,000
non-voting ordinary shares, NIS 0.01 nominal value per share, and 18,550,000
preferred shares, NIS 0.01 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    200,000,000 voting ordinary shares, of which approximately
          ordinary shares will be issued and outstanding;

     o    1,820,000 non-voting ordinary shares, of which approximately
          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 0.01 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,
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


                                       65


shares shall be issued, or to the holders of any other class of preferred shares
that we might authorize and issue in the 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 more than 50% of the outstanding
share capital. 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 21
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 February 29, 2000, options to purchase 3,986,516 of our ordinary
shares were outstanding under our 1998 Plan, our 102 Plan and Section 3(i) of
the Israeli Income Tax Ordinance, with a weighted average exercise price of
$1.24 per share. We also have outstanding warrants as of that date to purchase
an aggregate of 2,097,921 ordinary shares at a weighted average exercise price
of $6.09 per share.

REGISTRATION RIGHTS

     After this offering, the holders of approximately 15.5 million of our
ordinary shares have certain rights to register those shares under the
Securities Act of 1933 under a rights agreement. The 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 registrable securities 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


                                       66


portion of their shares in such registration, although the managing underwriter
of any such offering has certain rights 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.

RIGHTS TO PURCHASE SHARES IN OUR INITIAL PUBLIC OFFERING

     The holders of our Series C preferred shares have rights to purchase an
aggregate of 83,000,000 of the ordinary shares offered in our initial public
offering, based on the mid-point of the initial price range set forth in our
preliminary prospectus. The number of shares subject to this allocation may be
reduced if our board of directors determines in good faith that the issuance of
those shares would be materially detrimental to the success of the initial
public offering. The allocation is also subject to applicable legal and
regulatory limitations. Our board has not yet considered the foregoing share
allocations, and we are continuing to review the advisability and legality of
those allocations.

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.


                                       67



     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.

ISRAELI SECURITIES LAW REQUIREMENTS

     We have received from the Israeli securities authority an exemption from
Israel's prospectus delivery requirements applicable to the offering. We have
also received from the Israeli securities authority an exemption from the
reporting obligations to which Israeli companies whose shares are publicly
traded are subject, provided that a copy of each of the reports filed by us
under applicable United States securities laws shall be available for public
review at our offices in Israel.

TRANSFER AGENT AND REGISTRAR

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


                                       68



                         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      ordinary shares, assuming the exercise of outstanding warrants as of
February 29, 2000 to purchase 2,058,371 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 February 29, 2000. Of these outstanding
shares, the      shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act of 1933, unless
purchased by our affiliates, as that term is defined in Rule 144 under the
Securities Act of 1933. The remaining             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 of 1933. 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 of 1933, 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.

    NUMBER OF SHARES                             DATE
    ----------------                             ----

                          After 180 days from the date of this
                          prospectus, the 180 day lock-up terminates and these
                          shares are saleable under Rule 144 (subject in some
                          cases to volume limitations) or Rule 144(k)

                          After 180 days from the date of this prospectus, the
                          180 day lock-up is released and these shares are
                          saleable under Rule 701

                          After 180 days from the date of this prospectus,
                          restricted securities that are held for less than one
                          year and are not yet saleable under Rule 144

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         shares immediately after this offering;
           or

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

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


                                       69


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, pursuant to certain compensatory benefit
plans and contracts commencing 90 days after the issuer becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, in reliance upon
Rule 144 but without compliance with certain restrictions, including the holding
period requirements. 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 Securities
Exchange Act of 1934, 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 of
1933 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.


                                       70

                             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.


                                       71



       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.


                                       72



       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

                                       74


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 enterprises, 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.


                                       75


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.


                                       76



                              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 48 are, unless exempt, obligated to perform up to 39 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, Canada and Japan. 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


                                       77


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
agreement, dated      , 2000, we have agreed to sell to the underwriters named
below, 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:

        UNDERWRITERS                                          NUMBER OF 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           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        % 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 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        shares of the ordinary shares for employees, directors
and certain other persons associated with us who have expressed an interest


                                       79



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.

     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, Credit Suisse
First Boston Venture Fund I L.P. 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
these 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.

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

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

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

       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.

       o   Penalty bids permit the underwriters 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.

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

                          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.

auditors, have audited our consolidated financial statements as of December 31,
1998 and 1999, and for the period from our inception in June 1997 to December

1999 as set forth in their report. We have included our consolidated financial
statements and the related notes in the prospectus and elsewhere in the

                                    82



                       ENFORCEABILITY OF CIVIL LIABILITIES

     We are incorporated in the State of Israel, and some of our officers,
directors and the Israeli experts named herein are not residents of the United
States and substantially all of their assets may be located outside of United
States. The service of process upon, and the enforcement of judgements 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 or the Securities Exchange Act of 1934 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 thereof, 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.

a condition to that exemption, a copy of each of the reports we file with the
Securities and Exchange Commission pursuant to applicable U.S. law will be
available for review at our headquarters in Israel.

     We file reports with the Israeli Registrar of Companies regarding our
registered address, our registered capital, our shareholders of record and the
number of shares held by each shareholder, the identity of the directors and
details regarding security interests on our assets. In addition, we must file
with the Israeli Registrar of Companies our articles of association and a copy
of any special resolution adopted by a general meeting of shareholders. The
information filed with the Israeli Registrar of Companies is available to the
public. In addition to the information available to the public, our shareholders
are entitled, upon request, to review and receive copies of all minutes of
meetings of our shareholders.

                         REPORT OF INDEPENDENT AUDITORS

To the Shareholders of
XACCT TECHNOLOGIES (1997) LTD.

     We have audited the accompanying consolidated balance sheets of XACCT
Technologies (1997) 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) through
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 (1997) 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) through 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.

              (U.S. DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)


1. GENERAL

     XACCT Technologies (1997) 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 and cable network
     operators. The Company generates revenues principally from licensing its
     software products and, to a lesser extent, from services such as training,
     consulting, support and maintenance.

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

2. SIGNIFICANT ACCOUNTING POLICIES

     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 financial 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 the 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.

              (U.S. DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

     MARKETABLE SECURITIES

     In accordance with Statement of Financial Accounting Standards 115,
     "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS
     115"), the Company has classified its marketable debt into the
     available-for-sale category. (In applying SFAS 115 the Company is
     required to classify individual debt and equity securities into one of
     three categories: trading, held-to-maturity or available-for-sale).
     Securities classified as available for sale are reported at fair value.

     Unrecognized gains or losses on available-for-sale securities are included
     in equity until their disposition. Realized gains and losses and declines
     in value judged to be other than temporary on available-for-sale securities
     are included in interest income. The cost of securities sold is based on
     the specific identification method.

     Unrealized holding losses on available-for-sale securities at December 31,
     1999 were immaterial. There were no sales of securities during 1999.

     PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation is calculated by
     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

     RESEARCH AND DEVELOPMENT COSTS

     Research and development costs are charged to statements of operations as
     incurred.

     Statement of Financial Accounting Standards 86, "Accounting for the Costs
     of Computer Software to be Sold, Leased or Otherwise Marketed" ("SFAS 86"),
     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 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 generates revenues from licensing the rights to use its
     software products directly to end-users and indirectly through sub-license
     fees from resellers. The Company also generates


                                      F-8


                         XACCT TECHNOLOGIES (1997) LTD.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

              (U.S. DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)

     revenues from sales of professional services, including consulting,
     support, training and maintenance.

     Revenues from software license agreements are recognized, in accordance
     with Statement Of Position (SOP) 97-2 "Software Revenue Recognition" (as
     amended) when a software license agreement has been executed or a
     definitive purchase order has been received and the product has
     been delivered to the end customers, no significant obligations with regard
     to implementation remain, the fee is fixed and determinable and
     collectibility is probable.

     Service revenues are comprised of revenues from support arrangements,
     consulting fees and training. XACCT's policy is to recognize license
     revenues when these associated services are not essential to the
     functionality of the product. To date, these services have not been
     essential to the functionality of the product. Support arrangements provide
     technical support and the right to unspecified upgrades on an
     if-and-when-available basis. Revenues from support arrangements are
     deferred and recognized, on a straight-line basis, as services revenues,
     over the life of the related agreement, which is usually one year.
     Consulting and training revenues are deferred and recognized when provided
     to the customer. Customer advances and billed amounts due from customers,
     in excess of recognized revenues, are recorded as deferred revenues.

     In December 1998, the AICPA issued Statement of Position 98-9,
     "Modification of SOP 97-2, Software Revenue Recognition, With Respect to
     Certain Transactions". SOP 98-9 amends SOP 98-4 to extend the deferral of
     the application of certain passages of SOP 97-2 provided by SOP 98-4
     through fiscal years beginning on or before March 15, 1999. All other
     provisions of SOP 98-9 are effective for transactions entered into in
     fiscal years beginning after March 15, 1999.

     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 plan. 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 Financial Accounting Standards Board Statement No. 123
     "Accounting for Stock-Based Compensation" ("SFAS 123") with respect to
     options issued to non-employees. SFAS 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 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.

     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, accounts receivable,
     trade receivables, short-term bank deposits 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.

     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 Statement
     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
     Ordinary 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 and
     18,537,015 for the period from June 8, 1997 (inception) through December
     31, 1997 and for the years ended December 31, 1998 and 1999, 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 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).

     net loss per share (U.S. dollars in thousands, except share and per share
     data):

     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. Pro forma shareholders' equity at December 31, 1999,
     as adjusted for the assumed conversion of those shares outstanding at
     December 31, 1999, 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
     equivalents, short-term bank deposits and trade receivables. Cash and cash
     equivalents, and short-term bank deposits, 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. The Company's trade receivables
     are mainly derived from sales to customers in the United States and Europe.
     The Company has adopted credit policies and standards intended to
     accommodate industry growth and inherent risk. The Company performs ongoing
     credit evaluations of its customers' financial condition and generally does
     not require collateral.

     IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the Financial Accounting Standards Board issued Statement
     133, "Accounting for Derivative Instruments and Hedging Activities"
     ("Statement 133"). 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

     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 an Ordinary share on a one-to-one basis.

          Series B-1 and C-1 preferred shares, respectively, on a one-to-one
          basis, or into non-voting ordinary shares, pursuant to the conversion
          rate.

          All preferred shares shall be automatically converted into ordinary
          shares 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
          December 31, 1999.

          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

     As part of the issuance of shares in October 1999, the investors received
     warrants to purchase 1,201,158 Series C-1 preferred shares, with an
     exercise price of $7.82, related to 50% of the warrants, and $9.39, related
     to the other 50%. The first 50% of the warrants are exercisable through the
     earlier of the termination of a 24-month period, an IPO or liquidation of
     the Company.

     The remaining 50% of the warrants are exercisable through the earlier of
     the termination of a 30-months period, consummation of an IPO, or
     liquidation of the Company.

     its consultants warrants to purchase 63,700 ordinary shares at $0.71 per
     share. As of December 31, 1999, 57,820 warrants, have already been
     exercised. The remaining 5,880 warrants will be forfeited in June 2000.

     STOCK OPTIONS

     The Company has elected to follow Accounting Principles Board Opinion No.
     25, "Accounting for Shares Issued to Employees" ("APB-25"), and related
     interpretations, in accounting for its employee share options because, as
     discussed below, the alternative fair value accounting provided for under
     FASB Statement No. 123, "Accounting for Stock-Based Compensation", requires
     the use of option valuation models that were not developed for use in
     valuing employee share options.

     As at December 31, 1999, the Company has authorized through several
     Incentive Stock Option Plans, the grant of options to officers, management,
     other 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
     consecutive years of employment and expire eight years from the approval
     date of the option plan under the terms they were granted.

     Deferred compensation expenses which represent the excess of the market
     value over the exercise price totaled $3,205 and are amortized to the
     statements of operations over the vesting period which usually is four
     years.

     In 1998, the Company granted service providers options to purchase 23,170
     ordinary shares at an exercise price of $ 0.19. As of December 31, 1999,
     these options are fully vested. The Company accounts for these options in
     accordance with the provisions of SFAS 123. No compensation expense has
     been recorded in the consolidated financial statements regarding these
     options due to the insignificant amount of deferred compensation.

     In 1998, the Company granted a director 63,455 ordinary shares at an
     exercise price of $0.19. The shares are vested over a period of four years.

     Under SFAS 123, pro forma information regarding net loss and 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.

     The minimum value options pricing model was developed for use in estimating
     the fair value of traded options that have no vesting restrictions and are
     fully transferable. In addition, option

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

     Weighted-average fair values of options whose exercise price (1) equals, or
     (2) is less than the market price of the stock on date of grant are as
     follows:

8.   TAXES ON INCOME

     TAX BENEFITS UNDER THE 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 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 20% (depending on the rate of foreign 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

              (U.S. DOLLARS IN THOUSANDS EXCEPT PER SHARE AMOUNTS)


     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 enterprises 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 THE 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 LOSSES 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 liabilities and assets
     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.

       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


                                      II-1



       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.

       (b)    FINANCIAL STATEMENT SCHEDULES.

       Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the
consolidated financial statements or notes thereto.

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 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, 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, 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.


                                      II-7


                                   SIGNATURES

behalf by the undersigned, thereunto duly authorized, in the City of Santa
Clara, the State of California, on March 28, 2000.
