a leading global provider of outsourced integrated Web-based email and messaging
solutions to businesses.  Our solutions are flexible,  highly  customizable  and

email through their website to their end users.  As of December 31, 1999, we had
over 250 global customers.  Through our customers' sites we serve  approximately
8.4 million active emailboxes.  We also serve over 1.0 million active emailboxes
to small businesses and websites through our ZapZone Network.

Industry Background

Growth of the Internet Worldwide and Proliferation of Email

The Internet has become a vitally  important  global  medium for  communication,
commerce, content distribution and advertising.  International Data Corporation,
or IDC, estimates that as of December 1999, there were over 80 million Web users
in the United States and over 115 million users outside of the U.S. IDC

projects  that,  by the end of 2003,  these  numbers  will  increase to over 175
million Web users in the United States and over 325 million users outside of the
U.S.  This  growth  in  the  global  usage  of  the  Web  provides   significant
opportunities for emerging Web-based  businesses and other companies  developing
an online presence.

Email is one of the most widely used applications on the Internet and has become
a primary  platform  for  business  and  personal  communication.  According  to

                                                                          Page 2

Forrester Research,  over 80% of Internet users access their email while online,
making this activity the most popular use of the Internet. IDC estimates that at
the end of 1999 there were over 180 million  emailboxes in the United States and
over 130 million  outside of the United States.  IDC projects that by the end of
2003,  these numbers will increase to over 280 million  emailboxes in the United
States and over 305 million emailboxes outside the United States.

Web-based Email

Historically,  most email systems were provided by employers,  Internet  service
providers  (ISPs) or  universities  to individuals or closed groups of end users
through  software  applications  located  on the users'  desktops  or local area
networks.  Such email systems,  however, only permit access through the computer
or network on which the email  software  resides  or through  cumbersome  remote
access systems. The emergence of email systems that use Internet browsers as the
application for sending and receiving email has resulted in tremendous  advances
in email access,  functionality and ease of use. This email standard is commonly
referred to as "Web-based email."

Web-based email offers the following benefits over traditional closed systems:

     o   anytime,  anywhere  (universal)  access to both  business  and personal
         email accounts;

     o   advanced  integrated  communication  services  over  the  Web,  such as
         unified  messaging  (receiving  faxes  and  voicemail  via  email)  and
         integrated calendars and directories; and

     o   easy to use registration, setup and administration.

Businesses worldwide are seeking to differentiate themselves online. A Web-based
email service provides an optimal solution to address this business need because
it increases brand  awareness,  builds and reinforces a loyal,  connected member
base and facilitates commerce in the following ways:

     o   Companies embracing Web-based email can enhance their brand identity by
         controlling  the look and feel of their  Web-based  email interface and
         also by providing end users with  distinctive  branded email  addresses
         such as user@companyname.com.

     o   Web-based  email  significantly  enhances the frequency and duration of
         website visits, commonly referred to as the website's "stickiness." The
         personalized  nature  of  email  and  the  ability  to  bundle  it with
         additional  services,  such  as  calendaring,  scheduling  and  unified
         messaging,  establishes an important one-to-one relationship with email
         users.

     o   Email is  emerging as an  effective  application  for direct  marketing
         online,  as email users provide  important  demographic  data when they
         register for and use email  services.  This  information can be used to
         create highly targeted  marketing  campaigns with minimal  distribution
         costs.

The Opportunity to Provide Outsourced Web-based Email Services

While many organizations  worldwide  recognize the advantages of Web-based email
services,  they often lack the infrastructure,  expertise and resources to fully
realize  these  benefits  through  internal  development.  Due  to  the  growing
complexity of in-house email systems and the increasing levels of infrastructure
investment  and  management  resources  needed to  provide  comprehensive  email
services,  organizations  around  the  world  are  seeking  to  outsource  email
services.  Businesses  worldwide  seek to partner  with a dedicated  provider of
Web-based email to quickly implement high quality,  feature-rich  email services
without having to invest internally in email management and systems.

                                                                          Page 3

The Commtouch Solution

We are a  leading  global  provider  of  outsourced  Web-based  email  and other
messaging services to businesses worldwide. Our flexible and highly customizable
solutions enable us to satisfy the different email and messaging needs of a wide
range of customers.

Benefits of The Commtouch Solution

Extensive Email Features. Our solution is easy to use and provides a broad range
of  industry-leading  functionality.  This includes the ability for end users to
collect email from other email accounts, to create folders, to attach electronic
documents,  to store  messages,  to  maintain a contact  center,  to maintain an
integrated calendar, to create distribution lists and to establish user profiles
and signatures. Our service uses IMAP4, an advanced email protocol, which allows
email folders to be accessed from multiple email environments.

The value of our  solution is increased  by our  provision of premium  services,
which allow end users to send and receive  faxes,  voicemail  and pages from the
emailbox;  access  the  Web-based  emailbox  from an  off-line  client  (such as
Microsoft  Outlook);  and have email  forwarded to other  addresses.  We believe
that, by providing a single  platform which  integrates  multiple  communication
services and devices,  the  Web-based  emailbox we provide has the  potential to
become our end users' primary online communications center.

Ability to Support  Hundreds of Millions of Emailboxes.  Our modular  technology
architecture  enables the rapid set up of  full-service  hosting  facilities and
enables us to rapidly and easily  expand our system as our user base  grows.  In
addition,  we utilize  redundant  servers and server load balancing to re-direct
traffic to prevent service  interruptions.  Our system architecture and software
platform  have been  designed  to provide  high  quality  service to hundreds of
millions of emailboxes  across  millions of domains.  We believe that our robust
and  flexible  technology  platform  enables us to  maintain  one of the highest
service performance levels in the industry.

Customization.  Our solutions  enable our customers to leverage their email as a
brand building tool.  Customers offer our email and messaging  services to their
end users with the customer's  domain name. For example,  a customer can provide
email at its website with an address such as user@companyname.com. This repeated
visibility  of the  customer's  name  on  every  email  message  promotes  brand
awareness  and  customer  loyalty.  In  addition,  our  customers  can  use  our
proprietary  customization  tool to design the look and feel of their  Web-based
email interface so that it reflects their own brand image.

Rapidly  Deployable  and  Cost-Effective  Solutions. Our solutions for customers
can be implemented in as few as several days.

Our  flexible  technology  and  economies  of scale  enable us to provide  email
solutions in a cost-effective manner, allowing businesses to achieve significant
economic  advantages.  We believe  that this rapid time to market is critical to
our customers,  who desire to realize the benefits of Web-based email as quickly
as possible. We also provide comprehensive maintenance and administration of our
email  service,  which  eliminates  the need for our  customers to undertake the
significant burden of developing and maintaining an in-house email system.

Extensive Language  Capabilities.  We provide email services in the following 18
languages:  English,  Chinese (Simplified and Traditional),  Japanese,  Spanish,
French, German, Portuguese, Dutch, Finnish, Danish, Norwegian, Swedish, Russian,
Hebrew,  Icelandic,  Korean and Italian.  Additionally,  we can support multiple
languages on the same site for any of our customers and offer  spell-checking in
many of these languages.  Our multi-lingual  capabilities enable us to serve the
needs of businesses worldwide as well as multinational organizations.

Increased Website Usage. Our solutions  increase the potential for our customers
to generate  revenue by increasing the stickiness of their websites.  We believe
that traffic to our customers'  websites increases as end users frequently visit

                                                                          Page 4


<PAGE>


the website to check their email. The benefits of increased  website  stickiness
include more frequent  communication  with end users,  enhanced customer loyalty
and the opportunity to generate revenues from advertising,  direct marketing and
ecommerce transactions.

Online  Marketing  Capabilities.  Our customers can leverage our email solutions
along with the demographic  information of their end users to conduct one-to-one
marketing and targeted advertising campaigns. We collect demographic information
from  end  users  when  they  register  for  their  emailbox.  We  believe  this
information  provides a powerful platform on which to design targeted  marketing
campaigns.  To enhance our  customers'  marketing  capabilities,  we provide our
MailTarget  tool which enables them to select and deliver  tailored  messages to
targeted segments of their user population.

Commtouch Strategy

Our  objective is to be the leading  global  provider of  outsourced,  Web-based
integrated  email  and  messaging  services.  We plan to  achieve  this  goal by
pursuing the following key strategies:

Focus Sales and Marketing Efforts on Acquiring New Business Customers

We are  focused on selling  our  outsourced  email  communications  solution  to
business  customers,  which enables them to rapidly provide our service to their
users and customers  without needing to build or maintain an  infrastructure  to
support the service.  We target  customers who are  increasingly  relying on the
Internet to conduct their business and  communications but do not want to devote
the time and  resources to develop,  support,  or maintain an  integrated  email
service.  Commtouch  enables our  business  customers to quickly  implement  our
co-branded  "Powered by Commtouch" service with minimal upfront investment while
retaining their direct user and customer relationships.

We are focusing our business-to-business sales efforts on several target markets
which we believe are particularly receptive to using our solution. These include
application service providers (ASPs),  Internet service providers (ISPs),  large
corporations,   and  web  portals.   Businesses  in  these  target  markets  are
experiencing  increasing  pressure to offer  enhanced  Web-based  email to their
customers.  However,  because  they  need to  remain  focused  on their own core
business   operations,   we  believe  that  they  will  outsource   their  email
capabilities.

Accelerate Transition to a Price-Per-Emailbox Fee Structure

We generate an increasing  share of our revenue through a pricing strategy based
on a  per-emailbox  fee. We believe that this fee structure  results in a higher
and more  predictable  revenue  stream  compared  with  one  based on a share of
advertising  revenue.  Contracts with individual  business  customers  typically
include a guaranteed  revenue component and fees per emailbox based on the total
number of emailboxes and level of service provided.

Leverage Business Accounts Through Focused Sales Force

We believe that there is a significant  opportunity for us to further  penetrate
and derive increasing revenues from our existing customer base. A portion of our
sales force is dedicated to building our relationships  with existing  accounts,
selling them  product  upgrades and  enhancements  and keeping  abreast of their
growing email and messaging  requirements.  As our customers  grow,  develop new
online strategies and expand  geographically,  our sales force plans to identify
new ways we can offer them enhanced  messaging  services.  We believe this sales
effort will also serve to solidify our business relationships.

Extend International Leadership

We plan to  continue to  aggressively  market our  solutions  to  businesses  in
non-U.S. markets that we believe will experience significant growth in Web-based
email  usage.  We have  developed  multiple  language  interfaces  for our email
services to be used in the world's most widely used  non-English  languages.  We
have also established  marketing  groups in Israel,  to support our expansion in
Europe and Asia,  and in the United  States to support  our  expansion  in North
America and Latin America. We have a sales office in London, England and we plan
to open a sales office in Japan. Additionally,  we plan to pursue joint ventures

                                                                          Page 5


<PAGE>


with local partners in attractive non-U.S. markets to accelerate our penetration
globally.   We   believe   that  our   multi-language   capabilities,   targeted
international  sales efforts and  experience  in  penetrating  non-U.S.  markets
positions us favorably in non-U.S. markets.

Enhance Technology Leadership in Email Services

We intend to leverage our core  technology,  software  platform and expertise in
developing  and  managing a  comprehensive  Web-based  email  service to deliver
industry-leading functionality and advanced messaging services. We have recently
added new services,  including calendar  integration,  webmaster  administration
tools,  message boards,  list server features and HTML editing.  We also plan to
offer new services including email message language  translation and integration
of our email  services  with remote  personal  devices and wireless  access.  We
intend to continue to work closely with our customers to identify new trends and
functionality  that will be popular  with end users.  In  addition  to  internal
development,  we plan to seek,  partner with and invest in companies  developing
leading edge technologies to enhance our existing functionality.

Maintain Our Cost-Effective Technology Platform

Our proprietary,  open and scalable architecture gives us the flexibility to use
servers that provide us with the best  cost-quality  combination and to leverage
third-party  hosting  providers.  This  enables  us to  achieve  a  low  service
cost-per-emailbox  while  maintaining a high level of service  quality.  We will
seek to maintain this  cost-effective  technology  platform as we add additional
functionality and features to our solution.

Leverage Relationships with Go2Net, Vulcan Ventures and Microsoft


** 1 We entered into a strategic  relationship with Go2Net  simultaneously  with
the

** 2 closing of our initial  public  offering.  Our Customized  Web-Based  Email
Service

** 3 Agreement with Go2Net provides that we share revenues from advertising and

** 4 premium  services  offered to Go2Net's end users through our email service.
The

** 5 terms  of this  agreement  are  substantially  the  same as our  commercial
agreements

** 6 with other customers except that we have agreed that Go2Net will receive a

** 7 materially  greater  portion of advertising  revenues than other  customers
receive

** 8 under other similar agreements.  As part of this transaction,  we issued to
Go2Net

** 9 a warrant to purchase up to 1,136,000  ordinary shares at an exercise price
of

** 10 $12.80 per share. This warrant is exercisable at any time until it expires
on

** 11 July 16, 2004.  We agreed to register  these  shares,  the warrant and the
shares

** 12 issuable upon exercise of the warrant with the Securities and Exchange

** 13 Commission and the  registration  statement  relating to those  securities
became

** 14 effective on January 7, 2000. Exercise of the warrant will cause existing

** 15 investors significant  dilution.  However, we may not realize any revenues
or any

** 16 other  business  benefits  from this  strategic  relationship  with Go2Net
because we


** 17 and Go2Net may not be able to sell significant  amounts of advertising and
premium Web-based email services to Go2Net's end users.

** 18 We entered into an Email Services Agreement dated October 26, 1999 with

** 19 Microsoft  Corporation.   Under  this  agreement,   Commtouch  will,  at
Microsoft's

                                                                          Page 6

** 20 option, customize, host and maintain email services for Microsoft websites
in

** 21 the U.S. and  internationally.  Microsoft  will pay one-time  fees for the
set-up

** 22 and  customization  of the email  service for each website with respect to
which

** 23 Microsoft  chooses to use our services,  as well as quarterly service fees
for the

** 24 email  service  based on the number of mailboxes  hosted.  The term of the
agreement

** 25 shall continue for 12 months after the first commercial  distribution date
of the

** 26 email  service and Microsoft may extend the initial term on a quarterly or
annual basis upon 60 days prior written notice.  The agreement may be terminated
by

** 27 Microsoft for convenience upon 90 days' prior written notice, or by either
party upon a material  breach by the other party upon the terms specified in the
agreement. In connection with the agreement, Commtouch issued to Microsoft a

** 28 warrant,  exercisable  until  December  29, 1999,  to purchase  707,965 of
Commtouch's

** 29 ordinary shares at an exercise price of $28.25 per share for an aggregate

** 30 exercise  price of  approximately  $20.0  million.  On December  29, 1999,
Microsoft


** 31 exercised the warrant and now holds 707,965 ordinary shares. We agreed to


** 32  register  these  shares  with the  Commission.  The  registration  became
effective on

** 33 January 7, 2000.  However,  we may not realize  any  revenues or any other
business

** 34 benefits from this transaction  because  Microsoft is not obligated to use
our

** 35 services with respect to any website and has not agreed to provide us with
any

** 36 other business benefits.


Go2Net,  Vulcan Ventures and Microsoft have invested an aggregate of $40 million
in our Company.  Go2Net and Vulcan Ventures have a joint  representative  on our
Board of Directors  and we have entered into  business  relationships  with both
Go2Net and  Microsoft.  We will seek to leverage  our  relationships  with these
customers  to expand our service  offerings  to them and to gain access to other
potential customers with whom they have relationships.

through our customers we serve  approximately  8.4 million active emailboxes and
through our ZapZone Network service, which has over 190,000 sites registered, we
are serving  approximately  1.0 million active  emailboxes.  This extensive user
network,  along with our  advanced  technologies  and  strategic  relationships,
allows us to offer  value-added  direct marketing  services to our customers and
third parties. We currently provide the following services:

     Opt-in.  Users  can  elect to  receive  specific  newsletters  or  commerce
     offerings.  Whenever end users  choose to establish a direct  communication
     with one of our opt-in partners, we receive a referral fee.

     them to select and send tailored messages to targeted segments of their end
     user base.  We earn  revenues by charging  customers a fee for each message
     sent with this tool.

     Third-party  marketing  programs.  In addition to our own  internal  opt-in
     program,  we also provide other third-party direct marketing companies with
     the  opportunity  to  leverage  our  extensive  user base to  market  their
     products.  We  earn  revenues  by  charging  third-party  direct  marketing
     companies a fee for each message sent.

The ZapZone Network Email Service

Our ZapZone Network service delivers email messaging solutions to small websites
and homepages.  This service enables  individuals and website  administrators to
set  up  Web-based   email   online,   often  in  under  ten  minutes.   ZapZone
Network-enabled  sites are able to provide our core Web-based  email services to
their end users in multiple  languages.  Our  ZapZone  Network  service  enables
websites to collect valuable user  demographic  information,  which  facilitates
their  ability to  conduct  targeted  marketing  campaigns  with their  members.
Webmasters can then communicate with and market to those users.

Customers

We offer email and messaging communications services to businesses worldwide. As
of  December  31,  1999,  we  provided  our email  services  to over 250  global
customers. Our customer base includes Internet-centric businesses like community
sites and portals, and companies where a significant online presence is integral
to the overall enterprise. These customers represent a broad range of businesses
and services and are geographically diverse. We also have customers comprised of
small  websites and website  owners who offer  Web-based  email and messaging to
their end users through our ZapZone Network service.


Sales and Marketing

Sales Strategy

Our sales strategy is to target  businesses  worldwide  through a combination of
direct,  indirect and online  selling  initiatives.  While our  salespeople  are
responsible  for  selling  our  solutions  in  a  geographic  area,  they  often
collaborate   to  recruit  new   customers,   particularly   when  dealing  with
multinational  organizations.  Our sales  offices  are  located in Santa  Clara,
California, New York, New York, London, England, and Netanya, Israel. We plan to
extend our sales  force into  Europe  and Japan  within the next 12 months.  Our
sales force includes  salespeople who focus on acquiring new customers,  as well
as dedicated  salespeople who cultivate existing customers and seek to sell them
premium and other services.  As of December 31, 1999, we had 30 salespeople.  We
also plan to pursue joint  ventures with local  partners in attractive  non-U.S.
markets to assist us in the penetration of those markets.

Marketing Strategy

Our marketing strategy is focused on increasing global awareness of our solution
and  building  our  brand as a  leading  international  provider  of  email  and
messaging  services.  We plan to market our solution  primarily through a mix of
print advertising,  direct marketing,  public relations and online  initiatives.
Through  our  "Powered  by  Commtouch"  co-branding  of our  email  solution  on
customers'  websites,  we increase our brand awareness and receive a significant
number of  click-through  business leads.  We plan to  aggressively  promote our
premium services to our customers and their end users and our direct e-marketing
services to our  customers and third  parties.  We intend to leverage our direct
sales force and  develop  co-branding  and  marketing  opportunities  with other
online organizations to augment our marketing efforts.

                                                                         Page 11


<PAGE>



Customer Support

Commtouch  provides its customers  rapid callback  technical  support 24 hours a
day, seven days a week. We initally  developed a proprietary  software tool that
provides end users with  immediate  online  support  without  intervention  from
customer service  representatives or technical staff and subsequently have begun
implementation  of  other  customer  relationship  management  applications.  We
believe that this technical support model enables us to provide high quality and
cost-effective support service to our customers and end users.

Technology

We  leverage  our nine  years of  email  and  technology  experience  to  create
world-class,  robust,  full-featured,  reliable email solutions. We believe that
our  Web-based  email  solutions  possess  three  major  advantages  over  other
Web-based email solutions:

Scalable and Reliable Modular System Architecture

Our Web-based email system is designed to provide maximum  flexibility.  We have
developed  a system  architecture  consisting  of  three  main  components:  Web
servers,  mail servers and database servers. Web servers are responsible for the
front-end  email  application,  mail servers are responsible for the storage and
transmittal of email messages and database  servers are  responsible for storing
all other important end user and customer  information.  These servers  interact
through standard communications protocols such as HTTP, IMAP4, POP3 and SMTP and
ODBC.


                             Hardware Infrastructure

The modularity of our network  architecture  provides several key  technological
advantages:

Rapidly  deployable and  cost-effective.  The design of our system enables us to
significantly  reduce  our  deployment  time as well as  costs to  support  each
mailbox.

     o   We outsource server hosting and Internet backbone access to third party
         providers  because they are able to offer such  services at bulk rates.
         In addition,  there are numerous third-party providers from whom we can
         obtain these  services,  so our capacity is not limited and we are able
         to obtain  favorable  rates.  This  significantly  reduces our Internet
         connectivity and server maintenance costs.

     o   The  modularity  of our system  architecture  allows us to choose  from
         among a broad range of  industry-standard  mail servers, and select the
         servers with optimal price/performance  characteristics.  Again, we are
         able to obtain these servers from a number of vendors,  so our capacity
         is not limited.

     o   The  outsourcing  of our server needs  enables us to focus on the rapid
         deployment of  applications  for our clients  rather than on the costly
         and time-consuming  maintenance and development of an internal hardware
         infrastructure.

     o   Because  third-party mail servers are constantly upgraded with the most
         advanced features (LDAP support, HTML messaging,  etc.), we are able to
         reduce  our  development  time  by  leveraging  existing  off-the-shelf
         technology and immediately  integrating these features into our service
         offerings.

Scalable and reliable.  Our modular  technology  architecture  enables the rapid
setup of  full-service  email hosting  facilities  and enables us to quickly and
seamlessly  expand our system as our user base grows.  In  addition,  we utilize


                                                                         Page 12


<PAGE>



redundant servers and server load balancing capabilities to re-direct traffic if
a server  malfunctions.  Our system architecture and software platform have been
designed to provide  excellent  service to  hundreds  of millions of  emailboxes
across millions of domains.  We believe that our robust and flexible  technology
platform enables us to maintain one of the highest service performance levels in
the industry.

Portable. As the market for outsourced email systems evolves, some organizations
may demand their own in-house hosting facility. The highly modular nature of our
system  architecture  provides  us with the  ability  to  duplicate  a system in
another  location  within  a  period  of  several  days.  As a  result,  we  are
well-equipped  to rapidly  deploy email  services to this growing  subset of the
outsourced email systems market.

Proprietary Development Language

We  have  custom-built  a  proprietary   software  development  language  called
Application  Dynamic Markup Language (ADML) in order to maximize the flexibility
and minimize the development time of our email solutions.

The ADML  environment  encapsulates  the  functionality  and layout of a generic
Web-based email interface,  while allowing our developers to rapidly customize a
business partner's email system with specific features.  All external resources,
such as text strings, images and site-dependent parameters are stored in various
databases.  When a new  site is  built,  the  ADML  code is  compiled  into  ASP
(Microsoft's  Active Server Pages technology) code which runs on the web servers
and translates  the ADML code into HTML.  This enables the developer to build an
email interface for a business  partner without having to write a single line of
HTML code. This provides us with a competitive advantage for several reasons:

     o   we can add new  functionality  and  features  (languages,  premium  and
         direct marketing  services,  etc.) to any business  partner's  existing
         email system in as little as a few hours;

     o   we can simultaneously  upgrade more than one email system (for example,
         immediately making additional  languages available to any end user of a
         ZapZone Network service email site); and

     o   we can offer automated email  customization tools to our end users. For
         example, the ZapZone Network service takes advantage of the flexibility
         provided by ADML to allow  webmasters  to build,  customize  and deploy
         ready-to-use email sites in very little time.

Advanced Proprietary Technologies

We have developed the following proprietary technologies:

     o   Complex  Foreign  Language  Support.  Currently,  our  system  is fully
         double-byte-enabled  to handle  intricate  character  languages such as
         Chinese,  Korean and  Japanese,  as well as  right-to-left  support for
         languages like Hebrew and Arabic.

     o   Integrated  Open Platform  Interface.  We have  developed an integrated
         platform and series of application  programming  interfaces that enable
         us to rapidly and fully integrate  additional  communications  features
         and functionality into our service offering.

     o   Advanced  Direct  Marketing  Technology.  Our  MailTarget  service is a
         Web-based tool which provides customers with a user-friendly  method of
         selecting and  delivering  tailored  messages to a targeted  segment of
         their user populations.

     o   Customization  Wizard Tool. We have developed a proprietary  technology
         tool  which  enables  customers  to  design  the look and feel of their
         Web-based email interface so that it is consistent with their own brand
         images.

Competition

In the  market  for email and  messaging  services,  we  compete  directly  with
Web-based  email  service  providers,  including  Critical  Path,  Mail.com  and
USA.NET,  as well as with  companies  that develop and maintain  in-house  email
solutions.  In addition,  companies such as  Software.com  currently offer email
software products to ISPs, web hosting companies,  web portals and corporations.
Furthermore, numerous small-scale email providers offer low-cost basic services,
but  without  scalable  systems or  value-added  functionality.  These and other
companies   could   potentially   leverage  their  existing   capabilities   and
relationships  to enter the email service  industry by redesigning  their system
architecture,  pricing and  marketing  strategies  to sell through to the entire
market.   The  ability  of  these  competitors  to  offer  a  broader  suite  of
complementary  services may give them a  considerable  advantage over us. In the
future,  ISPs, web hosting  companies and outsourced  application  companies may
broaden their service offerings to include outsourced email.

Our market's level of  competition is likely to increase as current  competitors
increase the sophistication of their offerings and as new participants enter the
market.  In the future,  as we expand our service  offerings,  we may  encounter
increased competition in the development and delivery of these services. Many of
our current and potential  competitors have longer operating  histories,  larger
customer bases,  greater brand recognition and greater financial,  marketing and
other  resources  than  we  do  and  may  enter  into  strategic  or  commercial
relationships on more favorable terms.  Further,  certain of our competitors may
offer services at or below cost. In addition, new technologies and the expansion
of existing  technologies  may increase  competitive  pressures on us. Increased
competition may result in reduced operating margins and loss of market share.

We believe that our solution has the following competitive advantages:

     o   highly customizable and flexible;

     o   rapidly deployable;

     o   available in 18 languages;

     o   designed to integrate numerous messaging applications; and

     o   has the ability to effectively address multiple market needs.

However,  despite  our  competitive  positioning,  we may not be able to compete
successfully against current and future competitors.

Intellectual Property

We regard our copyrights,  service marks, trademarks,  trade secrets and similar
intellectual  property as critical to our  success,  and rely on  trademark  and
copyright  law,  trade secret  protection  and  confidentiality  and/or  license
agreements  with our  employees,  customers,  partners and others to protect our
proprietary  rights.  We have the  following  registered  trademarks:  COMMTOUCH
(registered in the U.S.); PRONTO (U.S. and other countries);  COMMTOUCH SOFTWARE
(Australia and New Zealand);  PRONTO FAMILY, PRONTO SECURE (Japan);  PRONTO MAIL
(Japan  and  New  Zealand).   We  also  have  the  following  pending  trademark
applications:  COMMTOUCH  (Israel and other  countries),  ZAPZONE  NETWORK,  ZZN
(U.S.,  Israel and other countries) and PRONTO (Mexico,  European  Community and
India).  It may be possible for  unauthorized  third  parties to copy or reverse
engineer  certain portions of our products or obtain and use information that we
regard as proprietary.  Certain end user license  provisions  protecting against
unauthorized use,  copying,  transfer and disclosure of the licensed program may
be unenforceable under the laws of certain  jurisdictions and foreign countries.
In  addition,  the laws of some  foreign  countries  do not protect  proprietary
rights to the same extent as do the laws of the United  States.  There can be no
assurance  that our means of  protecting  our  proprietary  rights in the United

                                                                         Page 14


<PAGE>



States  or  abroad  will  be  adequate  or that  competing  companies  will  not
independently develop similar technology.

Other parties may assert  infringement claims against us. We may also be subject
to legal  proceedings and claims from time to time in the ordinary course of our
business,  including claims of alleged  infringement of the trademarks and other
intellectual  property  rights of third  parties by us and our  licensees.  Such
claims, even if not meritorious,  could result in the expenditure of significant
financial and managerial resources.

Our ZapZone Network  service allows  webmasters to select the email service name
of their choice.  There is,  therefore,  the  possibility  that they will select
email  service  names that may infringe  the rights of others  under U.S.  state
and/or  federal or  foreign  trademark  and/or  anti-dilution  or similar  laws.
ZapZone  Network  service's  placement  of  ZapZone  Network  service  icons and
advertisements  on ZapZone Network service  webmasters' web pages may contribute
to our perceived  liability for any allegedly  infringing  acts. We do not audit
webmasters'  email  service name choices for  compliance  with any  intellectual
property rights of others. However, in our current webmaster license agreements,
we require  webmasters  to indemnify us for claims  resulting  from their chosen
email  service  names;  we also require  users to indemnify us in their  license
agreements. Furthermore, in our license agreements with webmasters and users, we
expressly  reserve the right to eliminate their account or to change their email
service names, in our sole discretion.  We have received complaints from several
parties  that email  service  names  chosen and  registered  by ZapZone  Network
service  users are similar or identical to domain  names  and/or  trademarks  in
which the  complainants  claim an interest.  We have  responded by reviewing the
content of the  complainants'  complaints,  and  either  (a)  sought  additional
substantiating  information  (b) requested a response to the complaint  from the
relevant  webmaster,  and/or (c)  changed or deleted the email  service  name in
question.

We also intend to continue to  strategically  license  certain  technology  from
third parties,  including our mail server and SSL encryption technology.  In the
future,  if we add  certificate  technology  to  our  systems,  we  may  license
additional  technology from third-party vendors. We cannot be certain that these
third-party content licenses will be available to us on commercially  reasonable
terms or that we will be able to successfully  integrate the technology into our
products and services.  These third-party in-licenses may expose us to increased
risks,  including risks associated with the assimilation of new technology,  the
diversion of resources from the development of our own  proprietary  technology,
and our inability to generate revenues from new technology  sufficient to offset
associated  acquisition  and maintenance  costs.  The inability to obtain any of
these licenses could result in delays in product and service  development  until
equivalent  technology  can be  identified,  licensed and  integrated.  Any such
delays in services could cause our business,  financial  condition and operating
results to suffer.

Government Regulation

There are currently few laws and regulations directly applicable to the Internet
and commercial email services.  Examples  include the Children's  Online Privacy
Protection  Act and related  regulations  in the U.S.  and  restrictions  on the
export of personal  data from the European  Community.  However,  it is possible
that a  number  of laws and  regulations  may be  adopted  with  respect  to the
Internet or  commercial  email  services  covering  issues such as user privacy,
pricing,  content,  copyright,  distribution,  antitrust and characteristics and
quality of products and services.  Further,  the growth and  development  of the
market for online email may prompt calls for more stringent consumer  protection
laws that may impose additional burdens on companies conducting business online.
The  adoption of  additional  laws or  regulations  may impair the growth of the
Internet or  commercial  online  services,  which could,  in turn,  decrease the
demand for our products and services and increase our cost of doing business, or
otherwise have a material adverse effect on our business,  operating results and
financial  condition.  Moreover,  the  applicability to the Internet of existing


                                                                         Page 15


<PAGE>



laws in various jurisdictions governing issues such as property ownership, sales
and other taxes,  libel and personal  privacy is uncertain and may take years to
resolve.  Any such 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 could have a
material  adverse  effect  on our  business,  operating  results  and  financial
condition.

Employees

As of  December  31,  1999,  we had 214  full-time  employees.  None of our U.S.
employees is covered by a collective bargaining  agreement.  We believe that our
relations with our employees are good.

Israeli law and  certain  provisions  of the  nationwide  collective  bargaining
agreements between the Histadrut (General Federation of Labor in Israel) and the
Coordinating  Bureau  of  Economic  Organizations  (the  Israeli  federation  of
employers'   organizations)  apply  to  Commtouch's  Israeli  employees.   These
provisions principally concern the maximum length of the work day and work week,
minimum  wages,  contributions  to a pension fund,  insurance  for  work-related
accidents,  procedures for dismissing employees,  determination of severance pay
and other  conditions of employment.  Furthermore,  pursuant to such provisions,
the  wages  of most of  Commtouch's  employees  are  subject  to cost of  living
adjustments,  based on changes in the Israeli  Consumer Price Index. The amounts
and frequency of such  adjustments  are modified from time to time.  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. Commtouch currently funds its ongoing severance
obligations by making monthly payments for insurance policies and by an accrual.

A general  practice  in Israel  followed  by  Commtouch,  although  not  legally
required,  is the  contribution  of funds on behalf of certain  employees  to an
individual insurance policy known as "Managers' Insurance." This policy provides
a  combination  of savings  plan,  insurance  and  severance pay benefits to the
insured  employee.  It provides for payments to the employee upon  retirement or
death and secures a substantial  portion of the severance  pay, if any, to which
the  employee  is  legally  entitled  upon   termination  of  employment.   Each
participating employee contributes an amount equal to 5% of such employee's base
salary, and the employer  contributes  between 13.3% and 15.8% of the employee's
base salary. Full-time employees who are not insured in this way are entitled to
a savings  account,  to which  each of the  employee  and the  employer  makes a
monthly  contribution  of 5% of  the  employee's  base  salary.  Commtouch  also
provides certain  employees with an Education Fund, to which each  participating
employee contributes an amount equal to 2.5% of such employee's base salary, and
the employer contributes an amount equal to 7.5% of the employee's base salary.


                                  RISK FACTORS

You should  carefully  consider the following  risk factors before you decide to
buy our ordinary shares.  You should also consider the other information in this
report.  If any of the following risks actually occur,  our business,  financial
condition,  operating  results  or cash  flows  could  be  materially  adversely
affected.  This could cause the trading price of our ordinary shares to decline,
and you could lose part or all of your investment.

This  report  contains   forward-looking   statements  that  involve  risks  and
uncertainties. These statements relate to our future plans, objectives, beliefs,
expectations  and intentions.  In some cases,  you can identify  forward-looking
statements  by our use of words such as  "expects,"  "anticipates,"  "believes,"
"intends,"  "plans," "seeks" and "estimates" and similar  expressions.  You will
find  forward-looking  statements under the captions  "Summary," "Risk Factors,"
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations"  and  "Business" and elsewhere in this report.  Our actual  results,
levels of activity, performance or achievements may differ materially from those


                                                                         Page 16


<PAGE>

expressed  or implied by these  forward-looking  statements.  Factors that could
cause or  contribute to these  differences  include  those  discussed  below and
elsewhere in this report.

Risks Relating to the Company

Because  we have a  limited  operating  history  as a  Web-based  email  service
provider, it is difficult to evaluate our business and prospects.

We commenced  operations in 1991, but we began  commercially  selling  Web-based
email  services only in 1998 after  changing our strategic  focus from the sale,
maintenance  and service of  stand-alone  email  client  software  products  for
mainframe and personal computers. This change required us to adjust our business
processes  and to  restructure  Commtouch  to become a Web-based  email  service
provider.  Therefore,  we have only a limited operating history as a provider of
Web-based email services upon which you can evaluate our business and prospects.

We have a history of losses and may never achieve profitability.

We incurred net losses of  approximately  $3.5 million in 1997,  $4.4 million in
1998 and $19.9 million in 1999.  As of December 31, 1999, we had an  accumulated
deficit of approximately  $31.5 million.  We have not achieved  profitability in
any period,  and we expect to  continue to incur net losses for the  foreseeable
future.

Our future email services revenues are unpredictable and our quarterly operating
results may fluctuate and fluctuations  could adversely affect the value of your
investment.

Because we have a limited  operating history in the provision of Web-based email
services and because of the emerging  nature of the markets in which we compete,
our revenue is  unpredictable.  Our current and future  expense  levels are to a
large extent fixed.  We may be unable to adjust  spending  quickly to compensate
for any revenue shortfall,  and any significant  revenue shortfall would have an
immediate negative effect on our results of operations and stock price.

A number  of  factors,  many of which  are  enumerated  in this  "Risk  Factors"
section,  are  likely to cause  fluctuations  in our  operating  results.  Other
factors which may cause such fluctuations include:

     o   the size, timing and fulfillment of orders for our email services;

     o   the  receipt  or payment  of  irregular  or  nonrecurring  revenues  or
         expenses;

     o   our mix of service  offerings,  including  our ability to  successfully
         implement new services;

     o   pricing of our services; and

     o   effectiveness of our customer support.

Because of these factors,  period-to-period comparisons of our operating results
are not a good  indication  of our  future  performance.  It is likely  that our
operating results in some quarters will be below market expectations.

We have recently  changed our fee  structure and cannot  predict the effect this
change will have on our future revenues.

In recent  months we have moved from a pricing  strategy  based  primarily  on a
share of  advertising  revenues with a minimum  annual  service fee to one based
primarily on charging a per-emailbox  fee with a minimum annual  commitment fee.
While we believe  that this new fee  structure  will result in a higher and more
predictable revenue stream compared with one based on a share of advertising

                                                                         Page 17


<PAGE>


revenues,  we cannot predict  whether this new pricing  strategy will in fact be
successful in generating  higher and more predictable  revenues.  We may need to
change our pricing strategy again from time to time.

If the market for our Web-based  email  services does not grow rapidly,  we will
fail to generate revenues.

Our success will depend on the widespread  acceptance and use of Web-based email
by our  customers  as a means to  increase  the value of their  services or as a
means of  communication.  The market for  Web-based  email  services  is new and
rapidly  evolving.  We cannot  estimate the size or growth rate of the potential
market for our service  offerings.  If the market for  Web-based  email fails to
grow or grows more slowly than we currently anticipate, our business will suffer
dramatically.  Even if that market  grows,  our  service  may not achieve  broad
market acceptance.  Since we have only recently  introduced our services,  we do
not have  sufficient  experience  to evaluate  whether they will  achieve  broad
market  acceptance.  Also,  because  all of our  revenue is derived  directly or
indirectly from our Web-based email solutions, if that market does not grow, our
business will likely fail.

If we do not expand our sales and marketing  organization we will not be able to
increase our revenues.

Our ability to increase our revenues will depend on our ability to  successfully
expand our sales and  marketing  organization.  The  complexity  of our Internet
messaging services and the emerging nature of the Web-based email market require
highly trained sales and marketing  personnel to educate  prospective  customers
regarding  the use and benefits of our  services.  The majority of our sales and
marketing  personnel  have  only  recently  joined  Commtouch  and have  limited
experience working together.  It will take time for these employees to learn how
to market  our  solutions  and to be  integrated  into our  sales and  marketing
organization.   Some  of  them  may  not  succeed  in  making  this  transition.
Additionally,  we are planning to introduce  additional services that we have no
experience  marketing  and will rely on these  services to produce a substantial
portion of our revenues in the future.  As a result of these factors,  our sales
and marketing  organization may not be able to compete  successfully against the
bigger  and  more   experienced   sales  and  marketing   organizations  of  our
competitors.

Even if our email services are successful with our customers,  we may not derive
revenue from the users of the emailboxes,  which would prevent our business from
growing.

Even if our services are a success with our customers, we will not succeed if we
do not derive revenue from the email users that our customers give us access to.
We plan to derive  revenue  from these email  users  primarily  by charging  our
customers per-emailbox fees for our email services, as well as by selling access
to email users for direct marketing services and from the sale of advertisements
that the email  users will see. If one or more of these  revenue  sources is not
successful, we will not succeed. To date, we have generated only limited revenue
from  these  potential  revenue  sources  and  they may not be  successful.  Our
existing  and  potential  customers  may not be  willing  to pay  for our  email
services.  Advertisers  and direct  marketers may not accept email as a means of
placing  advertisements  and conducting direct marketing and email users may not
want to receive direct marketing materials.

Our ability to generate revenues from the emailbox base that our customers bring
to us also  depends  on the  emailboxes  being  used on a regular  basis.  On an
ongoing  basis,  many of our end users will not regularly use their  emailboxes,
and a significant number will cease using our services each month.  Accordingly,
there may be no  relationship  between the number of active  emailboxes  and our
revenues.

                                                                         Page 18

<PAGE>




We depend on our customer  relationships,  which are based on  relatively  short
term, nonexclusive agreements,  and the loss of one or more customers could harm
our business.

Our  ability to increase  revenues  depends  upon  successful  marketing  of our
services through new and existing  customers.  Our agreements with our customers
generally can be terminated  for any or for no reason after the first year.  The
agreements  with our customers are  non-exclusive  and do not restrict them from
introducing   competing   services.   Also,  some  of  our  relationships  allow
termination  earlier  than one year.  Loss of one or a few key  customers  could
damage our reputation and hurt our ability to develop new  relationships.  If we
fail to develop new relationships or if our customers  terminate or do not renew
their  contracts  with us, our business will suffer,  as we will lose  potential
revenue from the lost customers and from their  underlying  base of email users.
One customer,  Excite,  accounted for 54% of our revenues in 1998. Revenues from
MyPoints,  a permission  based email  service  company,  represented  11% of our
revenues in 1999.  Customers may provide us with a large number of users but pay
a relatively small minimum annual service fee.

We have  many  established  competitors  who are  offering  the same or  similar
services  and we will not be able to compete  effectively  against  them if they
provide superior services at better prices.

The market for Web-based  email services is intensely  competitive and we expect
it to be increasingly competitive. Increased competition could result in pricing
pressures,  reduced  operating  margins and loss of market  share,  any of which
could cause our business to suffer.

In the  market  for email and  messaging  services,  we  compete  directly  with
Web-based  email  service  providers,  including  Critical  Path,  Mail.com  and
USA.NET,  as well as with  companies  that develop and maintain  in-house  email
solutions.  In addition,  companies such as  Software.com  currently offer email

                                                                         Page 19


<PAGE>

software products to ISPs, web hosting companies,  web portals and corporations.
Furthermore, numerous small-scale email providers offer low-cost basic services,
but  without  scalable  systems or  value-added  functionality.  These and other
companies   could   potentially   leverage  their  existing   capabilities   and
relationships  to enter the email service  industry by redesigning  their system
architecture,  pricing and  marketing  strategies  to sell through to the entire
market.   The  ability  of  these  competitors  to  offer  a  broader  suite  of
complementary  services may give them a  considerable  advantage over us. In the
future,  ISPs, web hosting  companies and outsourced  application  companies may
broaden their service offerings to include outsourced email.

Our market's level of  competition is likely to increase as current  competitors
increase the sophistication of their offerings and as new participants enter the
market.  In the future,  as we expand our service  offerings,  we may  encounter
increased competition in the development and delivery of these services. Many of
our current and potential  competitors have longer operating  histories,  larger
customer bases,  greater brand recognition and greater financial,  marketing and
other  resources  than  we  do  and  may  enter  into  strategic  or  commercial
relationships on more favorable terms.  Further,  certain of our competitors may
offer services at or below cost. In addition, new technologies and the expansion
of existing technologies may increase competitive pressures on us. We may not be
able  to  compete  successfully  against  current  and  future  competitors  and
increased competition may result in reduced operating margins and loss of market
share.

We are  experiencing  rapid internal growth which has and likely will strain our
management resources.

We recently began to expand our  operations  rapidly and intend to continue this
expansion. The number of employees increased from 45 on December 31, 1998 to 214
on December 31, 1999. This expansion has placed,  and is expected to continue to
place,  a  significant  strain  on our  managerial,  operational  and  financial
resources. To manage any further growth, we will also need to improve or replace
our existing operational, customer service and financial systems, procedures and
controls.

The loss of our key employees would  adversely  affect our ability to manage our
business,  therefore  causing our  operating  results to suffer and the value of
your investment to decline.

Our success  depends on the skills,  experience  and  performance  of our senior
management and other key personnel, many of whom have worked together for only a
short period of time.  The loss of the services of any of our senior  management
or other key personnel,  including Gideon Mantel,  our Chief Executive  Officer,
Isabel Maxwell, the President of our United States subsidiary, and Amir Lev, our
President and Chief Technical Officer, could materially and adversely affect our
business. We do not have employment agreements with any of our senior management
or other key  personnel.  We cannot prevent them from leaving at any time. We do
not maintain key-person life insurance policies on any of our employees.

Because our business is based on communications and messaging  services,  we are
susceptible to system interruptions and capacity  constraints,  which could harm
our business and reputation.

Our ability to  successfully  receive and send our end users' email messages and
provide  acceptable  levels of  service  largely  depends on the  efficient  and
uninterrupted  operation of our computer and communications hardware and network
systems and those of our outsourced hosting service. In addition,  the growth in
the  use of the  Internet  has  caused  frequent  interruptions  and  delays  in
accessing  the  Internet  and  transmitting  data over the  Internet.  We do not
possess  insurance to cover losses caused by unplanned system  interruptions and
software  defects.  In the past, we have experienced  some  interruptions in our
email service.  We believe that these  interruptions will continue to occur from
time to time. These  interruptions may be due to hardware failures,  unsolicited
bulk  email  (also  known as  "spam"),  operating  system  failures,  inadequate


                                                                         Page 20

<PAGE>


Internet  infrastructure  capacity,  and other  mechanical and human causes.  We
expect to experience  occasional,  temporary capacity constraints due to sharply
increased traffic,  which may cause  unanticipated  system  disruptions,  slower
response times,  impaired quality and degradation in levels of customer service.
If we experience  frequent or long system  interruptions that reduce our ability
to provide email  services,  we may have fewer users of our email  services.  In
addition,  we have entered into service  agreements  with some of our  customers
that require minimum performance standards.  If we fail to meet these standards,
our customers could terminate their relationships with us.

We must  continue  to expand and adapt our  network  infrastructure  to changing
requirements  and increasing  numbers of end users. The expansion and adaptation
of our network  infrastructure will require substantial  financial,  operational
and managerial  resources.  In addition, we depend on improvements being made to
the entire Internet  infrastructure  to alleviate  overloading and congestion of
the  Internet.  The  ability of our network to continue to connect and manage an
expanding  number of  customers,  end users and  messages  at high  transmission
speeds is unproven and uncertain. We face risks related to our network's and the
Internet's ability to operate with higher use levels while maintaining  expected
performance levels.

Although we are a leading global provider in our particular field of outsourced,
Web-based  email,  we  are a  relatively  small  competitor  in  the  electronic
messaging  industry as a whole.  As a result,  we may not have the  resources to
adapt to the  changing  technological  requirements  and the  shifting  consumer
preferences of our industry.

The Internet messaging industry is characterized by rapid technological  change,
changes in end user  requirements  and  preferences,  and the  emergence  of new
industry  standards  and practices  that could render our existing  services and
proprietary technology obsolete. Our success depends, in part, on our ability to
continually enhance our existing email and messaging services and to develop new
services,  functions and technology that address the increasingly  sophisticated
and varied needs of our  prospective  customers.  The development of proprietary
technology and necessary service enhancements entails significant  technical and
business risks and requires substantial  expenditures and lead-time.  We may not
be able to keep pace with the latest technological  developments.  We may not be
able to use new  technologies  effectively  or adapt our services to customer or
end user  requirements  or emerging  industry  standards.  Also,  in addition to
addressing  changing  technologies  and end user needs,  we must also do so more
quickly than our competition.

Our services may be adversely  affected by software  defects,  which could cause
our customers or end users to stop using our services.

Our  service  offerings  depend on  complex  software.  Complex  software  often
contains  defects,  particularly  when first introduced or when new versions are
released.  Although we conduct extensive  testing,  we may not discover software
defects that affect our new or current services or enhancements until after they
are deployed.  Although we have not experienced any material software defects to
date,  it is  possible  that,  despite  testing by us,  defects may exist in the
software we use.  These  defects could cause  service  interruptions  that could
damage our reputation or increase our service  costs,  cause us to lose revenue,
delay market acceptance or divert our development resources,  any of which could
cause our  business  to  suffer.  Some of our  services  are  based on  software
provided by third parties. We have no control over the quality of such software.

We rely on the integrity of our network  security,  which may be  susceptible to
breaches that could harm our reputation and business.

A fundamental  requirement for online  communications is the secure transmission
of confidential  information over public networks.  Third parties may attempt to
breach our  security or that of our  customers.  Despite our  implementation  of


                                                                         Page 21

third party encryption technology and network security measures, our servers are
vulnerable to computer  viruses,  physical or  electronic  break-ins and similar
disruptions,  which could lead to interruptions,  delays or loss of data. We may
be liable to our  customers  and their end users for any breach in our security,
including  claims for  impersonation  or other similar fraud claims,  as well as
claims for other misuses of personal  information,  for example for unauthorized
marketing  purposes.   Also,  such  a  breach  could  harm  our  reputation  and
consequently our business. We may also be required to expend significant capital
and other resources to license encryption technology and additional technologies
to protect  against  security  breaches or to alleviate  problems  caused by any
breach.  Our failure to prevent security  breaches could have a material adverse
effect on our business and operating results.

In  addition,  the  Federal  Trade  Commission  and  several  states  have  been
investigating   some  Internet   companies   regarding  their  use  of  personal
information. We could incur additional expenses if new regulations regarding the
use of  personal  information  are  introduced,  if our  privacy  practices  are
investigated  or if our  privacy  policies  are viewed  unfavorably  by users or
potential users.

If we fail to  adequately  protect our  intellectual  property  rights or face a
claim of intellectual  property infringement by a third party, we could lose our
intellectual property rights or be liable for significant damages.

We regard our copyrights,  service marks, trademarks,  trade secrets and similar
intellectual  property as critical to our  success,  and rely on  trademark  and
copyright law, trade secret protection and confidentiality or license agreements
with our  employees  and  customers  to protect our  proprietary  rights.  Third
parties may infringe or  misappropriate  our copyrights,  trademarks and similar
proprietary rights.  Although we have not filed any patent applications,  we may
seek to patent  certain  software or other  technology  in the future.  Any such
future  patent  applications  may not be issued  with the scope of the claims we
seek, or at all. We cannot be certain that our software does not infringe issued
patents that may relate to our software  products.  In addition,  because patent
applications in the United States are not publicly disclosed until the patent is
issued, applications may have been filed which relate to our software products.

Despite our precautions, unauthorized third parties may copy certain portions of
our technology or reverse  engineer or obtain and use information that we regard
as proprietary. End user license provisions protecting against unauthorized use,
copying,  transfer and disclosure of the licensed  program may be  unenforceable
under the laws of some  jurisdictions and foreign  countries.  In addition,  the
laws of some  foreign  countries do not protect  proprietary  rights to the same
extent  as do the  laws of the  United  States.  Our  means  of  protecting  our
proprietary  rights  in the  United  States or abroad  may not be  adequate  and
competitors may independently develop similar technology.

Our ZapZone Network  service allows  webmasters to select the email service name
of their choice  (although we reserve the right to eliminate their account or to
change their email service name).

There is,  therefore,  the possibility that they will select email service names
that may  infringe the rights of others.  We have  received  several  complaints
about ZapZone Network service webmasters'  registered email service names and we
have  referred  these  complainants  directly  to the  ZapZone  Network  service
subscribers who are allegedly  engaging in the infringing  activities.  However,
these  complainants  may seek to enforce their rights against us in addition to,
or instead of, the infringing webmasters.

We may have  liability for email content and we may not have adequate  liability
insurance.

As a provider of email  services,  we face potential  liability for  defamation,
negligence,  copyright,  patent or trademark infringement and other claims based
on the nature and content of the materials  transmitted via email. We do not and


                                                                         Page 22

cannot screen all of the content generated by end users, and we could be exposed
to liability with respect to this content. Some foreign governments, such as the
government of Germany,  have enforced  laws and  regulations  related to content
distributed over the Internet that are more strict than those currently in place
in the United  States.  Although  we carry  general and  professional  liability
insurance  coverage,  our  insurance  may not  adequately  protect  us from such
claims. Any imposition of liability,  particularly liability that is not covered
by insurance, or is in excess of insurance coverage, could damage our reputation
and hurt our  business  and  operating  results,  or could  result  in  criminal
penalties.

Governmental  regulation and legal  uncertainties could impair the growth of the
Internet  and  decrease  demand for our  services or increase  our cost of doing
business.

There are currently few laws and regulations directly applicable to the Internet
and  commercial  email  services.  However,  a number of laws have been proposed
involving  the  Internet,  including  laws  addressing  user  privacy,  pricing,
content, copyright,  antitrust,  distribution and characteristics and quality of
products and services.  Further,  the growth and  development  of the market for
email may prompt  calls for more  stringent  consumer  protection  laws that may
impose additional burdens on companies conducting business online. Moreover, the
applicability  to  the  Internet  of  existing  laws  in  various  jurisdictions
governing issues such as property  ownership,  sales and other taxes,  libel and
personal  privacy is  uncertain  and may take years to resolve.  The adoption of
additional  laws  or  regulations,  or  the  application  of  existing  laws  or
regulations to the Internet, may impair the growth of the Internet or commercial
online  services.  This could  decrease the demand for our services and increase
our  cost of doing  business,  or  otherwise  harm our  business  and  operating
results.

Due to  the  global  nature  of the  Web,  it is  possible  that,  although  our
transmissions currently originate in California, the governments of other states
or foreign  countries might attempt to regulate our  transmissions or levy sales
or other taxes relating to our activities. The European Union recently adopted a
directive  addressing  data privacy that may result in limits on the  collection
and use of user information.

On October 20,  1999,  The  Federal  Trade  Commission  issued the final rule to
implement the Children's  Online Privacy  Protection Act of 1998 ("COPPA").  The
main goal of the COPPA and the rule is to protect the privacy of children  using
the  Internet.  As of April 21,  2000,  certain  commercial  websites and online
services directed to, or that knowingly collect  information from, children must
obtain  parental  consent  before  collecting,  using,  or  disclosing  personal
information  from  children  under 13. The COPPA  regulations  could  reduce our
ability to engage in direct marketing. The cost to the Company of complying with
the new  requirements is not known and such cost may have a material effect upon
operating results or financial condition.

We may need  additional  capital  and  raising  additional  capital  may  dilute
existing shareholders.

We have invested heavily in technology and infrastructure development. We expect
to continue to spend substantial financial and other resources on developing and
introducing  new  service  offerings  and  expanding  our  sales  and  marketing
organizations,  strategic relationships and operating infrastructure.  We expect
that our expenses will continue to increase in absolute dollars. If our revenues
do not correspondingly  increase,  our operating results and financial condition
will be negatively affected.  We may never attain sufficient revenues to achieve
profitability.  If we do achieve  profitability,  we may not sustain or increase
profitability  in the  future.  This may,  in turn,  cause  our  stock  price to
decline.

We believe that our existing  capital  resources  will enable us to maintain our


                                                                         Page 23

current and planned operations for at least the next 12 months.  However, we may
be required to raise  additional funds due to unforeseen  circumstances.  If our
capital  requirements  vary  materially  from those  currently  planned,  we may
require additional financing sooner than anticipated.  Such financing may not be
available  in  sufficient  amounts  or on terms  acceptable  to us and may cause
dilution to existing shareholders.  Also, we may raise additional capital in the
future by issuing  securities  that have superior  rights and preferences to our
ordinary shares.

Our directors,  executive  officers and principal  shareholders  will be able to
exert  significant  influence over matters  requiring  shareholder  approval and
could delay or prevent a change of control.

Our directors and  affiliates of our directors,  our executive  officers and our
shareholders  who  currently  own  over  five  percent  of our  ordinary  shares
beneficially own approximately  30% of our outstanding  ordinary shares. If they
vote together, these shareholders will be able to exercise significant influence
over all matters  requiring  shareholder  approval,  including  the  election of
directors and approval of significant corporate transactions. This concentration
of ownership could also delay or prevent a change in control of Commtouch.

Go2Net and Vulcan Ventures beneficially own approximately 14% of our outstanding
ordinary  shares  (assuming  exercise  of the Go2Net  warrant on a net  issuance
basis).  Vulcan  Ventures is a significant  shareholder of Go2Net.  Accordingly,
Go2Net and Vulcan Ventures will be able to significantly  influence and possibly
exercise  control  over most  matters  requiring  approval by our  shareholders,
including  the  election of  directors  and  approval of  significant  corporate
transactions.  This  concentration  of  ownership  may also  have the  effect of
delaying  or  preventing  a change in  control.  Go2Net and Vulcan also have the
right to name one  director  to our  Board as long as they  continue  to hold at
least 620,022 shares,  including the shares issuable upon exercise of the Go2Net
warrant.  They have named  Thomas  Camp to the Board  under this  provision.  In
addition,  conflicts of interest may arise as a consequence of Go2Net's  control
relationship with us, including:

     o   conflicts   between   Go2Net  and  Vulcan   Ventures,   as  significant
         shareholders,  and our other  shareholders,  whose interests may differ
         with  respect to,  among  other  things,  our  strategic  direction  or
         significant corporate transactions;

     o   conflicts related to corporate  opportunities  that could be pursued by
         us, on the one hand, or by Go2Net, on the other hand; or

     o   conflicts related to existing or new contractual  relationships between
         us, on the one hand, and Go2Net and its other affiliates,  on the other
         hand.

Our  business  and  operating  results  could  suffer if we do not  successfully
address the risks inherent in the expansion of our international operations.

At present,  we have sales offices in the United States,  Israel and England. We
intend to continue to expand into international markets and to spend significant
financial  and  managerial  resources  to do so. We have limited  experience  in
international  operations  and  may  not  be  able  to  compete  effectively  in
international  markets.  The  Company  will face risks  inherent  in  conducting
business internationally, such as:

     o   difficulties   and  costs  of  staffing  and   managing   international
         operations;

     o   fluctuations in currency exchange rates;

     o   imposition of currency exchange controls;

     o   differing technology standards;


                                                                         Page 24


<PAGE>


     o   export  restrictions,  including export controls relating to encryption
         technologies;

     o   difficulties in collecting  accounts  receivable and longer  collection
         periods;

     o   unexpected changes in regulatory requirements;

     o   political and economic instability;

     o   potentially adverse tax consequences; and

     o   potentially reduced protection for intellectual property rights.

Any  of  these  factors  could  adversely  affect  the  Company's  international
operations  and,  consequently,  business and operating  results.  Specifically,
failure to  successfully  manage  international  growth  could  result in higher
operating  costs than  anticipated  or could  delay or preclude  altogether  the
Company's ability to generate revenues in key international markets.

Substantial sales of our ordinary shares could adversely affect our stock price.

The sale, or  availability  for sale, of substantial  quantities of our ordinary
shares  may have the  effect  of  depressing  its  market  price by  potentially
introducing  a large  number of sellers  into the market.  A large number of our
ordinary  shares are  currently  eligible for resale.  In addition a significant
number of shares will be eligible for resale at various dates in the future. See
"Shares Eligible for Future Sale."

Risks Relating to Operations in Israel

We have  important  facilities  and  resources  located  in  Israel,  which  has
historically  experienced severe economic instability and military and political
unrest.

We are  incorporated  under  the laws of the  State  of  Israel.  Our  principal
research   and   development   facilities   are  located  in  Israel.   Although
substantially  all of our sales  currently  are being made to customers  outside
Israel, we are nonetheless  directly  influenced by the political,  economic and
Military conditions affecting 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, operating results and financial
condition.

Israel's economy has been subject to numerous destabilizing factors, including a
period of rampant  inflation in the early to  mid-1980's,  low foreign  exchange
reserves,  fluctuations in world commodity prices,  military conflicts and civil
unrest.  In addition,  Israel and companies doing business with Israel have been
the  subject  of an  economic  boycott  by the  Arab  countries  since  Israel's
establishment. These restrictive laws and policies may have an adverse impact on
our operating results, financial condition or expansion of our business.

Since the establishment of the State of Israel in 1948, a state of hostility has
existed, varying in degree and intensity, between Israel and the Arab countries.
Although Israel has entered into various  agreements with certain Arab countries
and the  Palestinian  Authority,  and various  declarations  have been signed in
connection  with efforts to resolve some of the economic and political  problems
in the Middle East, we cannot  predict  whether or in what manner these problems
will be resolved.

Our results of operations  may be negatively  affected by the  obligation of key
personnel to perform military service.

In addition,  certain of our officers and employees  are currently  obligated to
perform  annual  reserve  duty in the Israel  Defense  Forces and are subject to
being  called for  active  military  duty at any time.  Although  Commtouch  has


                                                                         Page 25


<PAGE>


operated  effectively under these  requirements  since its inception,  we cannot
predict  the  effect  of these  obligations  on  Commtouch  in the  future.  Our
operations could be disrupted by the absence,  for a significant  period, of one
or more of our officers or key employees due to military service.

Because a  substantial  portion of our revenues are  generated in U.S.  dollars,
while a significant portion of our expenses are incurred in New Israeli Shekels,
our results of  operations  may be adversely  affected by inflation and currency
fluctuations.

We generate a  substantial  portion of our revenues in U.S.  dollars but incur a
significant portion of our expenses,  principally salaries and related personnel
expenses,  in New Israeli Shekels,  commonly referred to as NIS. As a result, we
are  exposed to the risk that the rate of  inflation  in Israel  will exceed the
rate of  devaluation  of the NIS in relation to the dollar or that the timing of
any  devaluation may lag behind  inflation in Israel.  While in recent years the
rate of  devaluation  of the NIS against the dollar has  generally  exceeded the
rate of inflation,  which is a reversal from prior years, we cannot be sure that
this  reversal  will  continue.  If the dollar cost of our  operations in Israel
increases, our dollar-measured results of operations will be adversely affected.
Our  operations  also  could be  adversely  affected  if we are  unable to guard
against  currency  fluctuations  in the future.  Accordingly,  we may enter into
currency  hedging  transactions to decrease the risk of financial  exposure from
fluctuations in the exchange rate of the dollar against the NIS. These measures,
however,  may not adequately protect us from material adverse effects due to the
impact of inflation in Israel.

Israeli  courts might not enforce  judgments  rendered  outside of Israel and it
might therefore be difficult for an investor to recover any judgment against any
of our officers or directors resident in Israel.

We  are  organized  under  the  laws  of  Israel,  and we  maintain  significant
operations in Israel. Certain of our officers and directors named in this report
reside outside of the United States. Therefore, you might not be able to enforce
any judgment  obtained in the U.S. against us or any of such persons.  You might
not be able to bring  civil  actions  under U.S.  securities  laws if you file a
lawsuit in Israel.  However,  we have been advised by our Israeli  counsel that,
subject to certain limitations, Israeli courts may enforce a final judgment of a
U.S. court for liquidated amounts in civil matters after a hearing in Israel. We
have appointed  Commtouch  Software Inc., our U.S.  subsidiary,  as our agent to
receive service of process in any action against us arising from this report. We
have not  given  our  consent  for our agent to accept  service  of  process  in
connection  with any  other  claim  and it may  therefore  be  difficult  for an
investor  to  effect  service  of  process  against  us or any  of our  non-U.S.
officers,  directors  and  experts  relating to any other  claims.  If a foreign
judgment  is  enforced  by an  Israeli  court,  it will be  payable  in  Israeli
currency.

Provisions of Israeli law may delay, prevent or make difficult an acquisition of
Commtouch,  which could  prevent a change of control and  therefore  depress the
price of our stock.

Israeli corporate law regulates  mergers,  votes required to approve mergers and
acquisitions  of shares through tender offers,  requires  special  approvals for
transactions involving significant shareholders and regulates other matters that
may be  relevant  to  these  types  of  transactions.  Furthermore,  Israel  tax
considerations may make potential  transactions  unappealing to us or to some of
our shareholders.

The new Israeli Companies Law imposes substantial duties on shareholders and may
cause uncertainties regarding corporate governance.

The new Israeli  Companies Law, which became  effective on February 1, 2000, has
brought about significant changes to Israeli corporate law. The new law includes
provisions   imposing    substantial   duties   on   certain   controlling   and
non-controlling shareholders.

                                                                         Page 26
