                             COMMTOUCH SOFTWARE LTD.

                            1,406,612 ORDINARY SHARES

         As we describe  further  below under  "Offer  Statistics  and  Expected
Timetable and Plan of Distribution," the Selling  Securityholders  identified in
this  prospectus  are selling up to 1,406,612 of our  ordinary  shares,  some of
which underlie warrants and options held by some of the Selling Securityholders.
The warrants and options  themselves  are not being offered by this  prospectus.
The Selling  Securityholders  acquired  the  ordinary  shares as a result of our
acquisition of Wingra Incorporated in December 2000. The ordinary shares offered
hereby have been  registered  pursuant  to  registration  rights  granted to the
Selling   Securityholders   by  the  Company  in  connection   with  the  Wingra
acquisition.  These  securities  may be offered from time to time by the Selling
Securityholders  through  public or private  transactions,  on or off the Nasdaq
National Market, at prevailing market prices or at privately  negotiated prices.
The Selling  Securityholders will receive all of the proceeds from this offering
and  will  pay all  underwriting  discounts  and  selling  commissions,  if any,
applicable  to the  sale  of  the  securities.  We  will  pay  the  expenses  of
registration of this offering.

         The Company has agreed to indemnify the Selling Securityholders against
certain liabilities,  including liabilities under the Securities Act of 1933, as
amended (the "Securities Act").

         In addition,  approximately  5% of the shares  being  offered are being
held in escrow  until  December 5, 2001 in  connection  with payment of possible
future  claims by us  arising  out of the  Wingra  acquisition.  Because of this
restriction,  the  Selling  Securityholders  have no present  intention  to sell
approximately  5% of the shares  being  offered by this  prospectus  until on or
after  December  5, 2001.  Also,  approximately  20% of the shares to which this
prospectus  relates  are  subject to an  agreement  between  us and the  Selling
Securityholders  which  prohibits  each of them from  transferring,  selling  or
otherwise  disposing  of his or her shares until  December 20, 2001.  Because of
this restriction,  the Selling Securityholders have no present intention to sell
approximately  20% of their  respective  ordinary  shares being  offered by this
prospectus until on or after December 20, 2001.

         The ordinary  shares are being  offered by the Selling  Securityholders
subject to prior sale,  subject to their  right to reject  offers in whole or in
part and subject to certain other conditions.

         The Selling  Securityholders may be deemed to be "underwriters"  within
the meaning of the Securities Act and any profits realized by them may be deemed
to be  underwriting  commissions.  Any  broker-dealers  that  participate in the
distribution  of  ordinary  shares also may be deemed to be  "underwriters,"  as
defined in the Securities Act, and any commissions or discounts paid to them, or
any profits realized by them upon the resale of any securities purchased by them
as principals,  may be deemed to be underwriting  commissions or discounts under
the Securities Act. The sale of the ordinary shares is subject to the prospectus
delivery requirements of the Securities Act.

         Our ordinary shares are currently  traded on the Nasdaq National Market
under the symbol  "CTCH." On September 24, 2001 the last reported sales price of
an ordinary share on the Nasdaq National Market was $0.22 per share.

         This investment involves risk. See "Risk Factors" beginning on page 5.

         Neither the Securities and Exchange Commission nor any state securities
Commission has approved or disapproved of these securities or determined if this
prospectus  is truthful or  complete.  Any  representation  to the contrary is a
criminal offense.


                The date of this Prospectus is September 26, 2001

         Unless  otherwise  indicated,  all  references  in this  prospectus  to
"Commtouch,"  "the Company," "we," "us" or "our" are to Commtouch  Software Ltd.
and its wholly-owned subsidiaries, Commtouch Inc., Commtouch (UK) Ltd, Commtouch
Latin  America  Inc.  and  Wingra  Technologies  Inc.,  and  its  majority-owned
subsidiary Commtouch K.K. (Japan).

COMMTOUCH

         We are a leading  global  provider of  outsourced  email and  messaging
solutions to small, medium and large enterprises and their service providers, as
well as internet-centric organizations including web portals and web sites.

         Our  main  target  customers   include  companies  that  specialize  in
providing  communications  applications to enterprises:  ASPs,  ISPs,  telecoms,
CLECs, wireless carriers, data centers, systems integrators, and IT consultants.

         Email and messaging is complex and requires focus to implement, deliver
and maintain.  Today's  robust  solutions  include:  the ability to address both
front-end and back-end requirements,  anytime-anywhere access, and features such
as anti-virus protection, unified messaging, calendaring, group scheduling, file
sharing,  and collaboration.  Technologies for the future are necessitating that
email and messaging adapt and change with the new  innovations.  With outsourced
email and messaging being less expensive to construct and maintain than in-house
"build"  solutions,  and with IT developers and  administrators in short supply,
and companies  needing to focus resources on their area of core  expertise,  the
demand for outsourced  email and messaging has  proliferated in the last several
years. 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. As rapid time to market is often critical to our customers,
our reputation for quick deployment is a significant advantage in the outsourced
email and marketing industry. Additionally, we provide comprehensive maintenance
and  administration  of our email  services,  which  eliminates the need for our
customers to undertake the  significant  burden of developing and maintaining an
in-house email system.

         With 10 years of  experience in email and messaging we have proven that
our solutions,  which utilize the cost-efficient  Microsoft NT(R) platform,  are
quickly deliverable,  scalable,  reliable,  and integrate well with a variety of
communications  applications that enterprises view as critical to providing them
with a mission critical service and competitive advantage in the marketplace.

         In  addition  to  providing   the   infrastructure   and  software  for
enterprise-grade  email and messaging  solutions,  we are also a  service-driven
company,  providing 24/7 management for the customer, either remotely or onsite.
We offer a variety of  professional  services to enterprises:  facilitating  the
transition from legacy email and messaging systems to new, advanced systems (via
our subsidiary Wingra  Technologies);  integrating email and messaging with such
applications as wireless  communications,  video and audio  communications,  and
customer relations management;  and allowing for unified communications in which
email,  instant messaging,  voice, and other data  communications are accessible
anytime, anywhere.

         We are  recognized  as one of the few  companies  with  the  depth  and
breadth of expertise in email and messaging. We currently partner with a variety
of  organizations.  We provide service level agreements (SLAs) for our customers
that use our enterprise-grade email and messaging solutions.

         We offer outsourced  anytime-anywhere  email and messaging solutions to
three segments of the market:

         Large enterprises and their service providers

                  act on that information with speed and intelligence.

         o        Our service is built on top-quality-hardware. The Microsoft(R)

                                       2




                  o        Our   domain-level   management   gives  the  service
                           provider the option of delegating  administration  to
                           its customer to lower the service  provider's support
                           costs.

                  o        Our detailed  reports provide  essential  information
                           for billing and usage statistics.

                  o        Our   ability   to  fully   secure   SSL   management
                           transactions  ensure that service  provider's data is
                           safe.

                  o        Our  Online  Management  Center  (OMC)  provides  the
                           service provider with a user-friendly  administration
                           interface  equipped  with a  broad-range  of  account
                           provisioning  functionality,  as  an  alternative  to
                           using APIs.

         Internet-centric  organizations (web portals and web sites that provide
free email and messaging to their customers and site visitors)

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

         o        The value of our  solution is  increased  by our  provision of
                  additional  services,  such as those  which allow end users to
                  send and receive 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.

         o        Our solutions  are aimed at  increasing  the potential for our
                  customers to generate  revenue by increasing the  "stickiness"
                  of their  websites.  We believe that traffic to our customers'
                  websites  should  increase as end users  frequently  visit the
                  website  to check  their  email.  The  benefits  of  increased
                  website  stickiness  include more frequent  communication with
                  end  users,   enhanced  customer  loyalty  and  the  potential
                  opportunity  to generate  revenues  from  advertising,  direct
                  marketing and e-commerce transactions.

         Because we have a limited operating history providing  outsourced email
services to the service provider,  telecommunications and enterprise markets, 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.
During the third  quarter of 2000,  we began the  process of  repositioning  the
company  to provide  outsourced  email and  messaging  services  to the  service
provider,  telecommunications  and enterprise  markets primarily through channel
partners.  This  change  required  us to adjust our  business  processes  and to
restructure Commtouch to become an outsourced email service provider. Therefore,
we have only a limited  operating  history as a provider of email  services upon
which you can evaluate our business and prospects.  It is too early to judge the
success of this service offering,  the enterprise focus and distribution through
channel partners.  We incurred net losses of approximately $4.4 million in 1998,
$19.9 million in 1999, $54.2 million in 2000 and $25.7 million for the first six
months  of  2001.  As of  June  30,  2001,  we had  an  accumulated  deficit  of
approximately $111.4 million. We have not achieved  profitability in any period,
and we expect to continue to incur net losses for the foreseeable  future. If we
do achieve  profitability,  we may not sustain or increase  profitability in the
future. This may, in turn, cause our share price to decline.

                                  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  prospectus.  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.
The risks described below are not the only ones facing us.  Additional risks not
presently known to us, or that we currently deem immaterial, may also impair our
business operations.

RECENT DEVELOPMENTS

         On January 2, 2001,  we  announced  that,  in the wake of the  economic
downturn and changes in market demand, we had initiated several internal changes
to better serve the enterprise  messaging market. These internal changes include
reducing our  operating  expenses  associated  with  supporting  the dot-com and
destination site markets, closing our e-commerce division and email services for
small community sites, and promoting  greater  efficiencies in channel sales and
marketing to the  enterprise  market.  Those changes were designed to reduce our
worldwide  headcount by approximately 20% and, combined with other cost savings,
reduce  overall  operating  expenses by $16 million from the operating  plan for
2001.

         On February 14, 2001, we reported a net loss for the fourth  quarter of
2000 of $24.1 million,  or a loss of $1.51 a share,  compared with a net loss of
$7.4 million,  or a loss of $0.51 a share for the fourth quarter of 1999.  Total
revenues  rose to $5.3  million for the quarter  from $2.2 million in the fourth
quarter of 1999.  We also said we  expected  to restate our revenue and net loss
for the first three quarters of 2000. We stated that first-quarter revenue would
be restated downwards to $3.6 million from $4.3 million,  second-quarter revenue
would be restated  downwards to $5.0 million from $5.9 million and third-quarter
revenue would be restated  downwards to $5.2 million from $8.1 million.  We said
our net loss for the first  quarter would be restated to $9.1 million from a net
loss of $8.5  million,  our  second-quarter  net loss would be restated to $10.8
million  from $9.9 million and our  third-quarter  net loss would be restated to
$10.2 million from $7.6 million. On March 22, 2001, we filed amendments to Forms
6-K which included restated financial statements for the first, second and third
quarters of 2000.

         On March 1, 2001, we announced that we are reorganizing our business to
enhance our focus on enterprise messaging solutions.  Accordingly,  we expect to
focus our operations on three enterprise  messaging  businesses:  Commtouch core
email and messaging service for the enterprise market which include the recently
launched  Microsoft Hosted Exchange service offering;  the enterprise  messaging
migration  and  integration   technologies  business  through  our  wholly-owned
subsidiary   Wingra   Technologies;    and   our   technology   development   of
next-generation    messaging    applications    for   marketing   to   worldwide
telecommunication  companies,  Internet Data Centers and service  providers.  We
said that as part of this  reorganization,  we would be streamlining  our global
operations and reducing our workforce by approximately 50%, to about 210 people.
We noted that the current global economic  environment  required that we incur a
significant reduction in expenses in order to enhance our financial strength and
maintain a sharp focus on the most promising  market  opportunities.  While this
reorganization  is expected to increase service and licensing  revenues,  we are
unable to predict if this strategy  will be  successful in enhancing  returns to
shareholders.

         Following our  restatement  of revenues for the first three quarters of
2000,  several class action  lawsuits  were filed in the United States  District
Court for the Northern  District of California,  against the Company and certain
of our officers and directors,  alleging violations of the antifraud  provisions
of the  Securities  Exchange Act of 1934 arising  from the  Company's  financial
statements. While we are unable to predict the ultimate outcome of these claims,
we believe they are without merit and intend to vigorously defend ourselves.

         On June 5, 2001 we entered into a Stock Purchase  Agreement (the "Stock
Purchase  Agreement")  with  Hughes  Holdings  LLC  ("Hughes").   The  following
discussion is qualified in its entirety by reference to the text of the purchase
agreement, which has been filed with the Commission as an exhibit to a report on
Form 6-K filed on June 12, 2001.

         Pursuant to the Stock  Purchase  Agreement,  (i)  commencing on June 6,
2001, and after all of the necessary approvals have been obtained, we shall sell
and Hughes shall purchase 850,000 ordinary shares,  par value NIS .05 per share,
of our capital stock (the  "Initial  Shares"),  at a minimum  amount of $250,000
weekly,  and (ii) for a period of four (4) months commencing on June 6, 2001 and
ending on October 6, 2001,  Hughes  shall have the option to  purchase  up to an
additional  1,400,000  ordinary  shares,  par  value NIS .05 per  share,  of our
capital  stock (the "Option  Shares").  In the event Hughes does not perform its
obligations  to purchase  the  minimum  amount of  $250,000  weekly,  during any
continuous two-week period during the term of the Stock Purchase Agreement,  any
and all of  Commtouch's  future  obligations  thereunder as to the Option

                                       5




Shares shall  terminate  with the exception of delivery of shares  purchased and
warrants owed under the terms of the Stock Purchase Agreement.

         In  addition,  at the  time of each  sale,  we shall  issue  to  Hughes
warrants  in a  proportion  of ten percent  (10%) of the Initial  Shares and the
Options  Shares,  as the case may be,  purchased  by Hughes to purchase up to an
additional  85,000 shares of our capital stock at an exercise price of $1.20 per
share in the event Hughes purchases all of the Initial Shares, and an additional
option to purchase up to 140,000  shares of our capital stock may be issued (the
"Option  Warrant")  in the event  Hughes  elects to  purchase  all of the Option
Shares.  The Option Warrant shall be exercisable  for shares of our common stock
at one hundred twenty  percent  (120%) of the applicable  purchase price (as set
forth below).

         Hughes'   purchase  price,   and  consequently  the  number  of  shares
purchased,  will fluctuate  based upon the daily volume  weighted  average price
over a 5-day trading period.  However,  if the pricing period is less than $0.75
cents Hughes can purchase  $250,000 worth of stock at the $0.75 less the allowed
10% discount or choose not to fund.  We will not be obligated to sell any Shares
pursuant to this Stock Purchase Agreement below the $0.75 less the 10% discount,
unless  otherwise agreed by Hughes and us. Hughes shall have no obligation to us
if the purchase  price falls below  $0.75.  Since our stock price has been below
$0.75 per share, this funding has never been concluded.

         The shares issuable to Hughes will originate from the 4,000,000  shares
previously  registered under a registration  statement declared effective by the
Securities and Exchange  Commission in December 2000, of which 3,684,211  shares
remain  after our  recent  sale of  315,789  shares to  Rideau  Ltd.,  a private
investor.

         The parties' obligations under the Stock Purchase Agreement are subject
to the fulfillment of certain conditions stated in the document, which we may or
may not be able to satisfy.  The  closing or closings of the Initial  Shares and
the Option  Shares,  as the case may be, will take place as soon as  practicable
after the closing conditions set forth in the Stock Purchase Agreement have been
met by the parties and in amounts of no less than  $250,000  and no greater than
$2,000,000 (per closing) worth of the Initial Shares or the Option Shares, which
shall be purchased weekly.

         In connection with our entering into the Stock Purchase Agreement,  the
Ordinary Share Purchase Agreement between Torneaux Fund Ltd., a Bahamian limited
liability company ("Torneaux"),  and the Company,  dated as of January 23, 2001,
in which we had an  option  for a  twenty-four  (24)  month  period  to sell our
ordinary shares to Torneaux for a maximum amount of $40,000,000,  was terminated
by Torneaux.

         During the second  quarter of 2001,  the  Company  implemented  a Board
approved   restructuring  plan.  The  restructuring  reduced  operating  expense
associated with serving  unprofitable and non-paying  dot-com,  destination site
and small  community  site  customers.  In  addition,  the  Company  closed  the
e-commerce  division and further reduced its workforce to about 160 people.  The
restructuring plan focused on increased  efficiencies  through channel sales and
marketing to the enterprise market.

         Also during the second quarter of 2001, we raised  additional equity of
$0.8 million to fund the expansion of our majority  owned  subsidiary  Commtouch
K.K. Japan.

         To limit  our cash  expenses  in 2001,  we have  significantly  reduced
staff,  curtailed  discretionary  expenses,  made available for sublease  excess
facilities and limited  capital  expenditures.  These actions were made due to a
decline in our revenue growth resulting from  competitive  factors and a slowing
economic environment. To enhance our overall financial position, we have entered
into an equity line  purchase  agreement  under which  Hughes  Holdings  LLC, an
institutional  investor,  has agreed to invest in the Company's  ordinary shares
provided the share price is above $.75 or a lower amount if mutually agreed. The
cash  realized  for the shares  sold will be  determined  based on the  weighted
average price of the shares in the month of placement. Since our stock price has
been below $0.75 per share, this funding has never been concluded.

         On July 24, 2001,  we reported a loss of $8.5 million and $25.7 million
for the quarter and the six months  ended June 30,  2001,  compared to a loss of
$10.8  million  and $19.9  million  for the  comparable  quarter  and six months
periods of 2000.

         Based  on the  cash  balance  at June  30,  2001 of $9.1  million,  the
expected  receipt of $1 million from a grant  approved by the Israeli  Office of
Chief Scientist ("OCS"), current projections of revenues,  related expenses, the
ability to further curtail certain  discretionary  expenses,  in accordance with
our ongoing board approved  contingency plan, and a potential funding capability
under the current Hughes equity line  arrangement  or other equity  arrangement,
the Company believes it has

                                       6




sufficient cash to continue  operations through at least June of 2002. The grant
from OCS to cover  research  and  development  expenses  is  dependent  upon the
Company's  fulfillment of its  commitments  under the OCS approval and the OCS's
satisfaction with the Company's R&D progress,  its ability to raise funds in the
capital markets and the status of the shareholders legal actions. The Company is
attempting to raise at least $5 million in  additional  funding in the near term
by issuing equity under our existing equity line arrangement with Hughes, and/or
seeking alternative sources of capital.  Accordingly, the Board of Directors has
retained  William  Blair & Company  to render  investment  banking  services  in
connection with a possible private placement of the Company's equity securities.
Since we have so far failed to secure that amount of funding, we have started to
implement our  contingency  plan which requires us to effect cost  reductions by
curtailing  research and development  operations,  human resources  expenses and
other costs so as to allow us to continue a reduced level of operations  through
at least June 30, 2002. We began making these  reductions in the second  quarter
of 2001.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In  June  2001,  the  Financial   Accounting   Standards  Board  issued
Statements of Financial Accounting Standards No. 141, Business Combinations, and
No. 142,  Goodwill  and Other  Intangible  Assets,  effective  for fiscal  years
beginning after December 15, 2001. Under the new rules,  goodwill and intangible
assets deemed to have  indefinite  lives will no longer be amortized but will be
subject to annual  impairment  tests in accordance  with the  Statements.  Other
intangible assets will continue to be amortized over their useful lives.

         The Company  will apply the new rules on  accounting  for  goodwill and
other intangible  assets beginning in the first quarter of 2002.  Application of
the  nonamortization  provisions  of the  Statement  is  expected to result in a
decrease in net loss of $2.5  million  ($0.15 per share) per year.  During 2002,
the Company will perform the first of the required  impairment tests of goodwill
and  indefinite  lived  intangible  assets as of January 1, 2002 and has not yet
determined  what the effect of these tests will be on the earnings and financial
position of the Company.  Until  December 31, 2001, the Company will continue to
perform the impairment  testing  according to Statement of Financial  Accounting
Standards No. 121.

BUSINESS RISKS

         If  the  market  for  our  outsourced  email  services  does  not  grow
significantly, we would fail to generate revenues.

         Our  success  will  depend on the  acceptance  and use of email that is
outsourced by  enterprises as a means of  communication  (as opposed to in-house
deployment).  The  market  for  outsourced  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 outsourced 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 a  preponderance  of our revenue is derived  directly or indirectly from
our outsourced email solutions,  if that market does not grow, our business will
likely fail.

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

         Because  we  have a  limited  operating  history  in the  provision  of
outsourced  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 share
price.

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

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

         o        The  success  of our  channel  and direct  selling  efforts to
                  enterprise customers;

         o        The  rate of  adoption  of  out-sourced  e-mail  solutions  by
                  enterprise customers in the current economic environment;

         o        The threat of  de-listing  by the NASDAQ if our shares  remain
                  below $1 for an extended period of time;

                                       7




         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 differing operating 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.  Because we have a limited operating history providing  outsourced
email  services  to the  service  provider,  telecommunications  and  enterprise
markets, 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. During the third quarter of 2000, we began
the  process  of  repositioning  the  company to  provide  outsourced  email and
messaging  services to the service provider,  telecommunications  and enterprise
markets primarily  through channel  partners.  This change required us to adjust
our business  processes  and to  restructure  Commtouch to become an  outsourced
email service provider. Therefore, we have only a limited operating history as a
provider  of email  services  upon  which  you can  evaluate  our  business  and
prospects.  It is too early to judge the success of this service  offering,  the
enterprise focus and distribution through channel partners.

         We have  many  established  competitors  who are  offering  the same or
similar services

         The market for outsourced  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  outsourced  email service  providers,  including  Critical Path,  Easylink
Corporation (formerly Mail.com),  USA.NET, United Messaging and USinteractive as
well as with companies that develop and maintain  in-house email  solutions such
as  Microsoft  and  IBM.  In  addition,  companies  such  as  Openwave,(formerly
Software.com)  and iPlanet  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. 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.

         Our  ability to  increase  our  revenues  will depend on our ability to
successfully execute our sales and marketing plan.

         The  complexity  of our  Internet  messaging  services and the emerging
nature of the outsourced 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 us and have  limited  experience  working  together.  In addition we have
limited experience in selling to enterprise  customers and in successful channel
selling.  It will  take  time for these  employees  to learn  how to market  our
enterprise  solutions  and  to  be  integrated  into  our  sales  and  marketing
organization.   Some  of  them  may  not  succeed  in  making  this  transition.
Additionally,  we are unable to predict the success in selling newly  introduced
additional  services  that we have no  experience  marketing  and are relying on
these  services to produce a substantial  portion of our revenues in the future.
As a result of these factors,  our sales and marketing

                                       8




organization may not be able to compete successfully against the bigger and more
experienced sales and marketing organizations of our competitors.

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

         We incurred net losses of  approximately  $4.4  million in 1998,  $19.9
million  in 1999,  $54.2  million  in 2000 and $25.7  million  for the first six
months  of  2001.  As of  June  30,  2001,  we had  an  accumulated  deficit  of
approximately $111.4 million. We have not achieved  profitability in any period,
and we expect to continue to incur net losses for the foreseeable  future. If we
do achieve  profitability,  we may not sustain or increase  profitability in the
future. This may, in turn, cause our share price to decline.

NEED FOR ADDITIONAL FUNDS

         We are dependent upon raising additional funds to finance our business.
Our cash balance at June 30, 2001 was $9.1 million.  We are  attempting to raise
at least $5 million in additional funding in the near term. Since we have so far
failed to secure  that  amount of  funding,  we have  started to  implement  our
contingency  plan which  requires us to effect  cost  reductions  by  curtailing
research and development operations, human resources expenses and other costs so
as to allow us to continue a reduced level of  operations  through at least June
30, 2002. We began making these reductions in the second quarter of 2001.

         Notwithstanding  initiation of the contingency plan, we may nonetheless
continue to be thinly  capitalized,  which may  adversely  affect our ability to
expand our operations, to recruit and retain employees, to enter into agreements
with vendors and customers, and to withstand changes in business conditions.  We
may,  therefore,  need to raise additional funds,  through  additional equity or
debt financing, collaborative relationships, strategic alliances with commercial
partners, or otherwise.  There can be no assurance that we will be able to raise
the necessary funds or that we will be able to do so on terms  acceptable to us.
Our inability to obtain adequate capital would limit our ability to continue our
operations.  Any such additional  funding may result in significant  dilution to
existing stockholders.

RISK OF RECESSION

         Some of our customers  continue to operate in the dot-com  market based
on internet-centric  business models and are experiencing a significant economic
slowdown and an inability to raise additional capital.

         Our  ability  to  collect  outstanding   receivables  is  significantly
impacted by the liquidity issues of these customers and this may also impact our
ability to sell future services and recognize  future revenue despite  committed
contracts from them.  This has had, and may continue to have, a negative  impact
on our ability to recognize  future revenues and as a result,  we may experience
unexpected shortfalls in our future revenues.

         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,  Amir  Lev,  our  President  and  Chief  Technical  Officer,  and Sunil
Bhardwaj,  our Chief Financial  Officer who recently joined us, 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.

         Our recent head-count reduction from 486 employees to approximately 160
is significantly straining our managerial,  operational and financial resources.
We have  significantly  curtailed  sales and  marketing  resources  and this may
compromise  our  ability to  enhance  revenues.  We also will incur  significant
expenditures  for wage  continuance  payments in connection  with this personnel
restructuring in order to comply with the WARN ACT 60 day notice requirements.

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

         At December  31, 2000 we had sales  offices in Israel,  United  States,
England,  Latin  America and Japan.  During the first quarter of 2001, we closed
sales offices in New York, Miami and England. We intend to continue to seek ways
to market

                                       9




our services in  international  markets by utilizing  significant  financial and
managerial resources. 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;

         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.

TECHNOLOGY RISKS

         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 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. To manage any further growth, we will
need to  improve or replace  our  existing  operational,  customer  service  and
financial systems as well as our procedures and controls.

         Although we are a leading global  provider in our  particular  field of
outsourced,  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, we must be able to
act 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.

         The loss of our right to use software  licensed to us by third  parties
could harm our business.

         We license technology that is incorporated into our products from third
parties,  including  security and encryption  software.  Any interruption in the
supply or support of any licensed  software  could  disrupt our  operations  and
delay our sales,  unless and until we can replace the functionality  provided by
this licensed software.  Because our products incorporate software developed and
maintained  by third  parties,  we depend on these third  parties to deliver and
support  reliable  products,   enhance  their  current  products,   develop  new
production on a timely and cost-effective basis and respond to emerging industry
standards and other technological changes.

         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  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.

                                       11




INVESTMENT RISKS

WE MAY NEED ADDITIONAL CAPITAL.

         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 maintaining our sales and
marketing and corporate management  organizations,  strategic  relationships and
operating  infrastructure.  We also expect to invest  substantial  resources  in
research and development projects to develop enhanced service provider messaging
solutions.

         Based on the cash  balance at June 30,  2001 of $9.1  million,  current
projections  of  revenues,  related  expenses,  the  ability to further  curtail
certain  discretionary  expenses in accordance with a board approved contingency
plan,  the  expected  receipt of $1 million  from the OCS as noted  above  under
"Recent  Developments,"  and a potential  funding  capability  under the current
equity line  arrangement  with Hughes or other equity  arrangement,  the Company
believes it has sufficient cash to continue operations through at least June 30,
2002.  However, to continue funding  developments of its software products,  the
company needs to raise at least $5 million of additional  cash by issuing equity
under its existing  equity line  arrangement,  and/or the Company  needs to seek
alternative sources of capital. Accordingly, the Board of Directors has retained
William Blair & Company to render investment banking services in connection with
a possible private placement of the Company's equity  securities.  Since we have
so far failed to secure that amount of funding, we have started to implement our
contingency  plan which  requires us to effect  cost  reductions  by  curtailing
research and development operations, human resources expenses and other costs so
as to allow us to continue a reduced level of  operations  through at least June
30, 2002. We began making these reductions in the second quarter of 2001.

         We are  subject to several  pending  lawsuits  the outcome of which may
have a material adverse effect on us.

         Following our  restatement  of revenues for the first three quarters of
2000,  several class action  lawsuits  were filed in the United States  District
Court for the Northern  District of California,  against the Company and certain
of our officers and directors,  alleging violations of the antifraud  provisions
of the  Securities  Exchange Act of 1934 arising  from the  Company's  financial
statements.  While we are unable to predict the ultimate outcome of these claims
we believe they are without merit and intend to vigorously defend ourselves.

         If we cannot satisfy Nasdaq's maintenance  requirements,  it may delist
our ordinary shares and we may not have an active public market for our ordinary
shares, which would likely make our shares an illiquid investment.

         Our  ordinary  shares  are  quoted on the Nasdaq  National  Market.  To
continue  to be listed,  our shares  must have a minimum  bid price of $1.00 per
share,  among other  requirements.  Recently,  our shares have had a minimum bid
price of substantially  less than $1.00 per share.  Consequently,  we may not be
able to satisfy the Nasdaq listing  requirement  in the future.  If this occurs,
trading in the shares may be  conducted  in the  over-the-counter  market in the
so-called "pink sheets" or, if available, the "OTC Bulletin Board Service." As a
result, an investor would likely find it significantly more difficult to dispose
of, or to obtain accurate quotations as to the value of, our shares.

         Nasdaq also may delist our shares if it deems it  necessary  to protect
investors and the public interest.

         If our shares are delisted, they may become subject to the SEC's "penny
stock" rules and more difficult to sell.

         SEC rules  require  brokers to provide  information  to  purchasers  of
securities  traded at less than $5.00 and not  traded on a  national  securities
exchange  or quoted on the Nasdaq  Stock  Market.  If our shares  become  "penny
stock" that is not exempt from these SEC rules,  these  disclosure  requirements
may have the effect of  reducing  trading  activity  in our shares and making it
more  difficult for  investors to sell.  The rules  require a  broker-dealer  to
deliver  a  standardized  risk  disclosure  document  prepared  by the SEC  that
provides information about penny stocks and the nature and level of risks in the
penny market.  The broker must also give bid and offer quotations and broker and
salesperson compensation information to the customer orally or in writing before
or with the confirmation.  The SEC rules also require a broker to make a special
written  determination  that the penny  stock is a suitable  investment  for the
purchaser  and receive the  purchaser's  written  agreement  to the  transaction
before a transaction in a penny stock.

         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.

                                       12




         Our directors and affiliates of our directors,  our executive  officers
and our  shareholders  who currently  individually  own over five percent of our
ordinary shares,  beneficially  own, in the aggregate,  approximately 25% 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.

         Jan  Eddy,  the  President  and  Chief  Executive   Officer  of  Wingra
Incorporated and Wingra Technologies, LLC, beneficially owns approximately 5% of
our outstanding ordinary shares issued to her in connection with our acquisition
of Wingra on December 5, 2000.

         InfoSpace   beneficially  owns  approximately  5%  of  our  outstanding
ordinary  shares.  InfoSpace  merged with Go2Net in October  2000. In connection
with this merger InfoSpace assumed Go2Net shares,  warrants and rights. In 1999,
in  connection  with  entering into an email  services  agreement,  we issued to
InfoSpace a warrant to purchase  1,136,000  ordinary shares at an exercise price
of  $12.80  per  share.  The  warrant  is  non-forfeitable,   fully  vested  and
immediately exercisable,  and will expire in July 2004. Assuming exercise of the
InfoSpace  warrant on a net issuance basis, the warrant  currently has no impact
on  beneficial  ownership,  as the warrant is  currently  higher than the market
value of our shares.

         These significant  shareholders 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.  InfoSpace  will also have the
right to name one director to our Board as long as it continues to hold at least
620,022  shares,  including  the shares  issuable upon exercise of the InfoSpace
warrant. In addition,  conflicts of interest may arise as a consequence of these
significant shareholders control relationship with us, including:

         o        conflicts  between  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 these  shareholders,  on
                  the other hand; or

         o        conflicts related to existing or new contractual relationships
                  between us, on the one hand,  and these  shareholders,  on the
                  other hand.

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

         The sale, or  availability  for sale, of substantial  quantities of our
ordinary  shares may have the effect of  depressing  its market  price.  A large
number  of  our  ordinary  shares  which  were  previously   subject  to  resale
restrictions,  are  currently  eligible  for resale.  In addition a  significant
number of shares will be eligible for resale at various dates in the future.

         As previously mentioned,  we have an agreement to issue equity under an
equity line agreement with Hughes Holdings Ltd., an institutional  investor. The
shares we issue under this agreement will dilute  existing  shareholders.  Since
our stock  price has been below  $0.75 per share,  this  funding  has never been
concluded.

         On November 2, 2000 the company  announced  its  acquisition  of Wingra
Technologies  for a  purchase  price of  approximately  1.29  million  Commtouch
ordinary shares and approximately 0.3 million fully vested Commtouch options and
warrants. The Company is required to register these shares. This prospectus is a
part of the registration  statement which we have filed to register those shares
(other than the shares underlying  options granted to employees  pursuant to the
Wingra  Technologies,  LLC 1998  Unit  Option  Plan,  which  were  covered  by a
Registration  Statement on Form S-8 which was filed and became effective on July
20,  2001).  Upon  effectiveness  of  the  registration  statement,  the  shares
registered  pursuant to the  registration  statement  can be freely traded which
could adversely impact our share price. This registration statement was declared
effective on September 6, 2001.

GOVERNMENTAL RISKS

         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.

                                       13




         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 within 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.

WE MAY HAVE LIABILITY FOR EMAIL CONTENT.

         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 cannot  screen all of the  content  generated  by end users.  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.  Any  imposition of
liability  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 previously 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 May 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.

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.  Recently,  the  military  unrest has  increased,  resulting in a higher
number of hostile actions.

         On September 11, 2001 terrorists attacked the World Trade Center in New
York City and the Pentagon in  Washington  DC. At this time,  the United  States
government  suspects that these  terrorists are from the Middle East. Any

                                       14




United  States  government  action  in the  Middle  East in  response  to  these
terrorist attacks could further increase  economic  instability and military and
political unrest in Israel and could significantly harm our business,  operating
results and financial condition.

         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 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.

         The government programs and benefits which we currently receive require
us to meet several conditions and may be terminated or reduced in the future.

         Prior to 1998,  we  received  grants  from the  Government  of  Israel,
through the OCS, for the financing of a significant  portion of our research and
development  expenditures in Israel.  In 2000 and 2001 we applied for additional
grants and we may apply for additional  grants in the future.  In 1998, 1999 and
2000 we did not receive any grants from the OCS and we expect the  percentage of
our research and development expenditures financed from OCS grants will continue
to remain quite low. In May 2001 we received  approval for a grant of $1 million
from the OCS. The grant is conditioned upon the Company  incurring  research and
development  expenses of at least $2 million  during 2001. The grant from OCS to
cover  research  and  development  expenses  is  dependent  upon  the  Company's
fulfilment of its commitments under the OCS approval and the OCS's  satisfaction
with the  Compnay's  R&D  progress,  its  ability to raise  funds in the capital
markets and the status of the  shareholders  legal  actions.  The OCS budget has
been subject to reductions  which may affect the availability of funds for these
grants in the future.  Therefore,  we cannot be certain that we will continue to
receive grants at the same rate, or at all. In addition, the terms of any future
OCS  grants may be less  favorable  than our past  grants.  In  connection  with
research  and

                                       15




development  grants received from the OCS, we must make royalty  payments to the
OCS of 3% - 5% of the revenue  derived from the sale of  products,  technologies
and  services  developed  with  grants  from the OCS unless  such  research  and
development projects are unsuccessful.

         The terms of the OCS  grants and the law  pursuant  to which the grants
are made restrict our ability to manufacture  products or transfer  technologies
developed  using OCS grants outside of Israel.  This  restriction  may limit our
ability to enter into agreements or similar  arrangements  for those products or
technologies,  without OCS approval.  We cannot be certain that the approvals of
the OCS will be obtained on terms that are acceptable to us. In connection  with
our grant applications, we have made representations and covenants with the OCS.
The funding from the OCS is subject to the accuracy of these representations and
covenants and to our compliance with the conditions and restrictions  imposed by
the OCS. If we fail to comply with any of these conditions or  restrictions,  we
could be  required  to repay  any  grants  previously  received,  together  with
interest and  penalties,  and would likely be  ineligible  to receive OCS grants
thereafter.

         The tax benefits we are  currently  entitled to from the  Government of
Israel may be reduced or terminated in the future.

         Pursuant to the Law for the Encouragement of Capital  Investments,  the
Government  of Israel  through  the  Investment  Center  has  granted  "approved
enterprise"  status to a  significant  portion of our research  and  development
efforts.  The portion of our income derived from our approved enterprise program
will be exempt  from tax for a limited  period  commencing  in the first year in
which  have  taxable  income,  and  will  be  subject  to a  reduced  tax for an
additional  period.  The  benefits  available  to  an  approved  enterprise  are
conditioned  upon the  fulfillment of conditions  regarding a required amount of
investments in fixed assets and a portion of these  investments  being made with
net proceeds of equity  capital raised by us as stipulated in applicable law and
in the  specific  certificates  of  approval.  If we fail to comply  with  these
conditions,  in whole or in part, we may be required to pay additional taxes for
the period in which we benefited from the tax exemption or reduced tax rates and
would  likely be denied  these  benefits in the future.  From time to time,  the
Government  of  Israel  has  discussed  reducing  or  eliminating  the  benefits
available under the approved  enterprise  program. It is possible that these tax
benefits may not be continued in the future at their current levels or at all.

         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  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 Inc., our U.S. subsidiary,  as our agent to receive service of process
in any  action  against  us arising  from this  offering.  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 may 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 shares.

         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.

         Proposed tax reform in Israel may reduce our tax benefits,  which might
adversely affect our profitability.

         On May 4, 2000 a committee  chaired by the former  Director  General of
the Israeli Ministry of Finance, Avi Ben-Bassat,  issued a report recommending a
sweeping  reform in the Israeli  system of taxation.  The proposed  reform would
significantly alter the taxation of individuals, and would also affect corporate
taxation.  In particular,  the proposed reform would reduce,  but not eliminate,
the tax benefits  available to approved  enterprises  such as ours.  The Israeli
cabinet approved the  recommendations  in principle,  but  implementation of the
reform requires  legislation by Israel's Knesset.  In the interim, a new Israeli
government has been formed,  and there are  indications  that the new government
may eliminate  significant  aspects

                                       16




of the proposed reform. We cannot be certain whether the proposed reform will be
adopted, when it will be adopted or what form any reform will ultimately take.

         The new Israeli  Companies  Law, to which we are  subject,  has not yet
been interpreted by the courts.

         The new Israeli  Companies Law became effective as of February 1, 2000,
instituting major and  comprehensive  changes to Israeli corporate law. To date,
Israeli courts have not fully reviewed or interpreted  certain important aspects
of the new Israeli Companies Law.  Furthermore,  to date the Israeli Minister of
Justice has promulgated only a portion of the regulations  required to implement
the new  Israeli  Companies  Law.  As a  result,  there  remain  many  questions
concerning the  application  of the law, and  shareholders  instituting  actions
against Israeli companies,  or against their directors,  officers or controlling
shareholders,   may  experience  difficulties,   as  well  as  uncertainties  in
protecting their interests.

                    REASONS FOR THE OFFER AND USE OF PROCEEDS

         We will not  receive  any  proceeds  from the sale of the shares by the
Selling Securityholders in this offering.


                             SELLING SECURITYHOLDERS

         The  following  table  presents  information  provided  by the  Selling
Securityholders  with respect to beneficial  ownership of our ordinary shares as
of June 30, 2001,  and as adjusted to reflect the sale of the shares  offered by
this  prospectus,  by the Selling  Securityholders  and assumes  that all shares
being  offered by this  prospectus  are  ultimately  sold in the offering by the
Selling Securityholders.


         The table includes all shares  issuable within 60 days of June 30, 2001
upon the exercise of options,  warrants and other rights  beneficially  owned by
the indicated shareholders on that date. Beneficial ownership as set forth below
includes the power to direct the voting or the  disposition of the securities or
to  receive  the  economic  benefit  of  ownership  of  the  securities.  To our
knowledge,  except  under  applicable  community  property  laws or as otherwise
indicated,  the persons named in the table have sole voting and sole  investment
control with respect to all shares beneficially owned. The applicable percentage
of  ownership  for  each  shareholder  is based on  17,286,373  ordinary  shares
outstanding  as of June 30,  2001 and  17,407,702  ordinary  shares  outstanding
immediately following the completion of this offering,  together with applicable
options and/or warrants for that shareholder that are exercisable within 60 days
of June 30, 2001.

                          DESCRIPTION OF SHARE CAPITAL

DESCRIPTION OF SHARES

         Set forth below is a summary of the material  provisions  governing our
share capital. This summary is not complete and should be read together with our
Memorandum of Association and Articles of Association, copies of which have been
filed as exhibits  to our Annual  Report on Form 20-F,  as  amended,  subject to
amendment of our Articles of Association from time to time.

         As of  June  30,  2001,  our  authorized  share  capital  consisted  of
40,000,000  ordinary shares, NIS 0.05 par value. As of June 30, 2001, there were
17,286,373 ordinary shares and no preferred shares issued and outstanding.

DESCRIPTION OF ORDINARY SHARES

         All  issued  and  outstanding  ordinary  shares of  Commtouch  are duly
authorized and validly issued, fully paid and nonassessable. The ordinary shares
do not have preemptive rights.  Neither our Memorandum of Association,  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 which are in a state of war with Israel.

DIVIDEND AND LIQUIDATION RIGHTS

         The ordinary  shares  offered by this  prospectus are entitled to their
full  proportion  of any cash or share  dividend  declared from the date of this
prospectus.

         Subject to the rights of the  holders of shares  with  preferential  or
other special rights that may be authorized,  the holders of ordinary shares are
entitled to receive  dividends in  proportion to the sums paid up or credited as
paid up on account of the  nominal  value of their  respective  holdings  of the
shares in  respect of which the  dividend  is being paid  (without  taking  into
account the  premium  paid up on the  shares)  out of assets  legally  available
therefor  and, in the event of our  winding  up, to share  ratably in all assets
remaining  after  payment of  liabilities  in proportion to the nominal value of
their respective holdings of the shares in respect of which such distribution is
being  made,  subject to  applicable  law.  Our Board of  Directors  may declare
interim  dividends and recommend a final annual dividend only out of profits and
in such  amounts as the Board of Directors  may  determine.  Declaration  of the
final annual dividend requires shareholder approval at a general meeting,  which
may reduce but not increase  such dividend  from the amount  recommended  by the
Board of Directors.

         In case of a share dividend,  holders of shares can receive shares of a
class whether such class existed prior thereto or was created therefor or shares
of the same class that  conferred  upon the  holders  the right to receive  such
dividend.

VOTING, SHAREHOLDER MEETINGS AND RESOLUTIONS

         Holders of ordinary  shares have one vote for each ordinary  share held
on all matters submitted to a vote of shareholders.  Such rights may be affected
by the future  grant of any special  voting  rights to the holders of a class of
shares with  preferential  rights.  Once the  creation of a class of shares with
preference rights has been approved,  the Board of Directors may issue preferred
shares, unless the Board is limited from doing so by the Articles of Association
or a contractual provision.

         An annual general meeting must be held once every calendar year at such
time (not more than 15 months after the last preceding  annual general  meeting)
and at such  place,  either  within or outside  the State of  Israel,  as may be
determined by the Board of Directors.  The quorum required for a general meeting
of shareholders  consists of at least two  shareholders  present in person or by
proxy and holding,  or representing,  more than one-quarter of the voting rights
of the issued share  capital.  A meeting  adjourned  for lack of a quorum may be
adjourned  to the same day in the next  week at the same time and  place,  or to
such time and place as the Board of Directors may determine.  At such reconvened
meeting any two  shareholders  present in person or by proxy (and not in default
under the articles) will constitute a quorum.  Shareholder  resolutions  will be

                                       21




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.

ANTI-TAKEOVER PROVISIONS UNDER ISRAELI LAW

         Under the Companies Law, a merger is generally  required to be approved
by the shareholders and board of directors 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.  The  Companies  Law  provides  that the  articles of  association  of
companies,  such as ours, that were  incorporated  prior to February 1, 2000 are
deemed to  include a  provision  whereby  the  approval  of a merger  requires a
majority of three  quarters of those present and voting at a general  meeting of
shareholders.  In addition,  a merger can be completed  only after all approvals
have been  submitted to the Israeli  Registrar of Companies and at least seventy
days have  passed from the time that a proposal  for  approval of the merger was
filed with the Registrar.

         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 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 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.

         Finally,  Israeli tax law treats  specified  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.

TRANSFER OF SHARES AND NOTICES

         Fully paid  ordinary  shares are issued in  registered  form and may be
transferred  freely.  Each shareholder of record is entitled to receive at least
seven days' prior notice of shareholder  meetings.  A special  resolution can be
adopted only if  shareholders  are given 21 days' prior notice of the meeting at
which such resolution will be voted on (unless all shareholders entitled to vote
agree that the meeting may be held on a shorter notice period).  For purposes of
determining the shareholders entitled to notice and to vote at such meeting, the
Board of  Directors  may fix the record date not  exceeding 90 days prior to the
date of any general meeting.

MODIFICATION OF CLASS RIGHTS

         If at any time the 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 by Commtouch by a special
resolution subject to the consent in writing of the holders of the issued shares
of the class,  or by the adoption of a special  resolution  passed at a separate
general meeting of the holders of the shares of such class.

DESCRIPTION OF INVESTOR OPTIONS AND WARRANTS

INFOSPACE WARRANT

         In connection  with the Customized  Web-based  Email Service  Agreement
entered into between Commtouch and Go2Net (subsequently  acquired by InfoSpace),
Commtouch  issued to  InfoSpace  a fully  vested,  non-forfeitable,  warrant  to
purchase  1,136,000  ordinary  shares at a per-share  exercise  price of $12.80,
subject to adjustment as provided in the warrant.  The warrant is exercisable at
any time until it expires on July 16, 2004. At InfoSpace's  option,  the warrant
is  exercisable  pursuant to a cashless  exercise  based on the average  closing
price of the  ordinary  shares for the five days  preceding  the  exercise.  The
Company extended  registration  rights to InfoSpace covering the warrant and the
shares  issuable  upon  exercise

                                       22




of the warrant and a registration statement relating to the resale of the shares
and the warrant  became  effective on January 7, 2000. The holder of the warrant
is required to avoid  becoming a 10% or greater  shareholder of the Company as a
result of any exercise of the warrant.

         The holder of the  warrant is given the  opportunity  to profit  from a
rise in the market  price of the ordinary  shares and the  warrant.  The warrant
includes  provisions  which adjust the exercise and price upon the occurrence of
certain events which might otherwise dilute the value of the warrant.

WINGRA WARRANTS AND OPTIONS

         In connection with our acquisition of Wingra,  we assumed  warrants and
options to purchase 137,233 shares issued to the Wingra investors  (subsequently
reduced  to  121,329  due to  expiration  of certain  options),  and  options to
purchase 168,382 ordinary shares to Wingra  employees  (subsequently  reduced to
162,257  due  to  expiration  of  options  of   terminating   employees).   Upon
effectiveness  of the merger,  these  warrants  and options  became  immediately
exercisable.

         The assumed  investor  warrants and options were  originally  issued by
Wingra  in  connection  with  loans to Wingra  by banks  and  shareholders.  The
exercise  prices of those warrants and options range from $6.29 to $9.35 and the
expiration dates range from July 2002 through March 2004.

         The employee stock options were originally  granted to Wingra employees
under the Wingra Technologies, LLC 1998 Unit Option Plan. The exercise prices of
those options range from $0.2010 to $3.5010 and the expiration  dates range from
August 2008 through July 2010. At the time of the merger,  we assumed the rights
and obligations under that Option Plan.

REGISTRATION RIGHTS

         The holders of convertible  preferred  shares which were converted into
7,109,800  ordinary shares (the "Registrable  Securities") upon effectiveness of
the initial public offering,  have certain rights to register those shares under
the  Securities  Act. If requested  by holders of a majority of the  Registrable
Securities  after  the  second  anniversary  of the date of the  initial  public
offering,  Commtouch must file a registration statement under the Securities Act
covering all Registrable  Securities  requested to be included by all holders of
such Registrable Securities.  Commtouch may be required to effect up to two such
registrations.  Commtouch has the right to delay any such registration for up to
120 days under certain circumstances, but not more than once during any 12-month
period.

         In  addition,  if  Commtouch  proposes to register  any of its ordinary
shares under the Securities Act other than in connection with a company employee
benefit  plan or a  corporate  reorganization  pursuant  to Rule 145  under  the
Securities Act, or a registration on any registration  form that does not permit
secondary sales or does not include  substantially the same information as would
be  required to be included in a  registration  statement  covering  the sale of
Registrable  Securities,  the  holders of  Registrable  Securities  may  require
Commtouch  to  include  all or a portion of their  shares in such  registration,
although the managing  underwriter  of any such  offering has certain  rights to
limit the number of shares in such registration.

         Further,  a majority  of the  holders  of  Registrable  Securities  may
require Commtouch to register all or any portion of their Registrable Securities
on Form F-3,  subject  to  certain  conditions  and  limitations.  All  expenses
incurred in connection  with all  registrations  (other than fees,  expenses and
disbursements of counsel retained by the holders of the Registrable  Shares, and
underwriters'  and  brokers'   discounts  and  commissions)  will  be  borne  by
Commtouch.

         The  registration  rights  described in the preceding three  paragraphs
expire five years after the closing date of our initial  public  offering  (July
16, 2004).

         In addition,  the Company  granted  registration  rights to  InfoSpace,
Vulcan  Ventures and Microsoft  pursuant to which their  holdings in the Company
(including the warrant issued to InfoSpace) were registered on January 7, 2000.

         Also,  under  the terms of the  Wingra  acquisition  agreement,  we are
required to register the 1,568,869  shares issuable to the Wingra  investors and
employees,  including  shares  currently  issuable  under  options and  warrants
described above.  The registration  statement of which this prospectus is a part
and a Form S-8 registration statement were filed to fulfill this requirement and
became effective, respectively, on September 6, 2001 and July 20, 2001.

                                       23




ACCESS TO INFORMATION

         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,  the  identity  of the  directors  and  details
regarding  security  interests on our assets.  In addition,  Commtouch must file
with the Israeli  Registrar of Companies its Articles of Association  and a copy
of any special  resolution  adopted by a general  meeting of  shareholders.  The
information filed with the 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.

TRANSFER AGENT AND REGISTRAR

         The transfer agent and registrar for our ordinary shares is Wells Fargo
Minnesota N.A.


                         SHARES ELIGIBLE FOR FUTURE SALE

         Future  sales of  substantial  amounts  of our  ordinary  shares in the
public market,  or the  possibility of these sales  occurring,  could  adversely
affect prevailing market prices for our ordinary shares or our future ability to
raise capital through an offering of equity securities.

         As of June 30, 2001 we had 17,286,373 ordinary shares outstanding.  The
3,450,000  ordinary shares sold in our initial public offering in July 1999; the
1,344,086  ordinary shares and the warrant  exercisable  for 1,136,000  ordinary
shares of  InfoSpace  and  Vulcan  Ventures  registered  in 2000 in a  secondary
offering along with the 707,965  ordinary shares held by Microsoft  Corporation;
and the 315,789 shares we issued to Rideau Ltd., a private investor, on June 30,
2001,  are (or, in the case of the InfoSpace  warrant,  will be upon exercise of
the warrant) freely tradable in the public market without  restriction under the
Securities Act,  unless the shares are held by  "affiliates" of the Company,  as
that term is defined in Rule 144 under the  Securities  Act.  In  addition,  the
1,406,612 shares to which this prospectus  relates will also be freely tradeable
without  restriction,  unless  otherwise  indicated  in the  related  prospectus
supplement.

         In connection  with our acquisition of Wingra,  we issued  1,285,294 of
our ordinary shares to the Wingra investors (including fractional shares payable
in  cash),  and as noted  above we  assumed  warrants  and  options  to issue an
additional  137,233 shares to those investors  (subsequently  reduced to 121,329
due to expiration  of certain  options),  and options to issue 168,382  ordinary
shares to Wingra employees (subsequently reduced to 162,257 due to expiration of
options of terminating employees). Further, 20% of the shares issued or issuable
in connection with our acquisition of Wingra are subject to an agreement between
us and the Wingra  investors  which  prohibits  each of them from  transferring,
selling or otherwise  disposing of these  shares until  December 20, 2001.  Five
percent of these shares are held in escrow until  December 5, 2001 in connection
with payment of possible future claims by us arising out of the acquisition.  We
are  required to register all of these  shares.  The  registration  statement of
which this  prospectus  is a part was filed to fulfill  this  requirement  as to
1,406,612 shares and became effective on September 6, 2001. On July 20, 2001, we
filed an  additional  registration  statement  on Form S-8 to cover the employee
stock options which became  exercisable for our shares upon  consummation of the
acquisition,  which became  effective on that date. Upon  effectiveness of these
registrations,  the shares can be freely  traded  (subject  to the  restrictions
noted), which could adversely impact our share price.

         Also, the 850,000 shares to be issued to Hughes Holdings LLC and the up
to  1,400,000  additional  shares  which Hughes will have an option to purchase,
noted above under "Risk Factors--Recent Developments," will be freely tradeable,
as will the warrants  which we may issue to Hughes for 85,000 shares and 140,000
shares,  respectively,  in connection with these two purchases.  Since our stock
price has been below $0.75 per share, this funding has never been concluded.

         The 3,684,211 shares remaining under our shelf  registration  statement
after the  recent  issuance  of  315,789  shares to Rideau  Ltd.  will be freely
tradeable  once issued.  The shares to be issued to Hughes will  originate  from
this registration statement.

         The  remaining  ordinary  shares  outstanding  upon  completion of this
offering will be "restricted securities" as that term is defined under Rule 144.
We issued and sold  these  restricted  securities  in  private  transactions  in
reliance on exemptions from  registration  under the Securities Act.  Restricted
securities  may be sold in the public  market only if they are  registered or if
they qualify for an exemption from registration under Rule 144 or Rule 701 under
the Securities Act, as summarized below.

                                       24




SHARES SUBJECT TO RESTRICTION UNDER RULE 144

         Most of the  restricted  shares are subject to certain volume and other
resale  restrictions  pursuant to Rule 144 because the holders are affiliates of
Commtouch.  In general,  under Rule 144, an affiliate of Commtouch,  or a person
(including a group of related persons whose shares must be aggregated  under the
Rule) who has beneficially  owned restricted  shares for at least one year, will
be entitled to sell in any  three-month  period a number of shares that does not
exceed the greater of

         o        1% of the  then  outstanding  ordinary  shares  (approximately
                  174,077  shares  immediately   following   completion  of  the
                  offering), or

         o        the average  weekly  trading  volume  during the four calendar
                  weeks  preceding the date on which notice of the sale is filed
                  with the Commission.

         Sales pursuant to Rule 144 are subject to certain requirements relating
to manner of sale,  notice and availability of current public  information about
Commtouch. A person who was not an affiliate of Commtouch for 90 days before the
sale and who has  beneficially  owned the shares for at least two years may sell
under Rule 144(k) without regard to the above limitations.

SHARES UNDER EMPLOYEE BENEFIT PLANS

         On January 20, 2000, we filed a Form S-8  registration  statement under
the Securities Act to register  5,400,000 ordinary shares issuable in connection
with option exercises and shares reserved for issuance under all stock plans and
agreements as well as 150,000 ordinary shares under the Company's Employee Stock
Purchase  Plan which the Company may issue to employees  from time to time.  The
Company also issues  employee and director stock options from time to time. Such
options are subject to vesting  periods  after which the shares may be resold by
the holders,  subject to Rule 144 limitations if the holder is an affiliate.  Of
2,404,390  options issued,  989,387 option shares were vested and unexercised as
of June 30, 2001 and 1,145,014 options had been exercised. On July 20, 2001, the
Company filed another Form S-8 registration statement to register: an additional
250,000 of our ordinary shares  approved by our  shareholders on August 10, 2000
for issuance  under the  Company's  director  stock option plan;  an  additional
79,156 shares  issuable  under our Employee  Stock  Purchase  Plan;  and 162,257
shares underlying  options issuable to employees of Wingra pursuant to the terms
of the Wingra merger agreement and the Wingra Technologies, LLC 1998 Unit Option
Plan.

         On April 30, 2001 our Board of Directors  approved the  "repricing"  of
outstanding stock options previously  granted to employees,  contingent upon the
completion of certain  regulatory  filings.  Previously  granted options will be
cancelled and new options will be issued with an exercise price equal to the par
value of the  shares.  Options  subject to the  repricing  must have an original
exercise price of more than $10 per share and must be currently unexercised. The
options will vest over three years with 1/3 vesting on February 15, 2002 and the
remaining 2/3 vesting every six months for the next two years.  After regulatory
filings are completed, if these repriced options are issued the decreased option
exercise price may cause  optionees to exercise  options  immediately and resell
the shares received in the exercise on the open market, which may cause downward
pressure on the price of the shares.  Options to purchase  1,521,988  shares are
covered by this repricing.

ADDITIONAL RESTRICTIONS

         In addition to the restrictions imposed by the securities laws, 493,660
restricted  shares were issued to certain  Commtouch  employees under agreements
which give  Commtouch  Inc. a  repurchase  option on any  unvested  shares.  The
repurchase  option lapses ratably over time. As of June 30, 2001,  approximately
13,733 ordinary shares are subject to repurchase.

         In addition,  approximately  5% of the shares  being  offered are being
held in escrow  until  December 5, 2001 in  connection  with payment of possible
future  claims by us  arising  out of the  Wingra  acquisition.  Because of this
restriction,  the  Selling  Securityholders  have no present  intention  to sell
approximately  5% of the shares  being  offered by this  prospectus  until on or
after  December  5, 2001.  Also,  approximately  20% of the shares to which this
prospectus  relates  are  subject to an  agreement  between  us and the  Selling
Securityholders  which  prohibits  each of them from  transferring,  selling  or
otherwise  disposing  of his or her shares until  December 20, 2001.  Because of
this restriction,  the Selling Securityholders have no present intention to sell
approximately  20% of their  respective  ordinary  shares being  offered by this
prospectus until on or after December 20, 2001.

                                       25




        OFFER STATISTICS AND EXPECTED TIMETABLE AND PLAN OF DISTRIBUTION

         The Selling  Securityholders may sell, directly or through brokers, the
ordinary shares in one or more long or short  transactions  at fixed prices,  at
market prices at the time of sale, at varying  prices  determined at the time of
sale or at negotiated  prices.  As noted above under "Shares Eligible for Future
Sale--Additional Restrictions," certain of the shares covered by this prospectus
are subject to contractual  agreements entered into by the Selling  Shareholders
by which such shares may not be resold until  certain time periods have elapsed.
Although  none of the  Selling  Securityholders  has advised us of the manner in
which such  Securityholder  currently  intends to sell its ordinary shares,  the
Selling  Securityholders  may choose to sell all or a portion  (or none) of such
shares from time to time in one or more of the following transactions:

         o        On any national  securities  exchange or quotation  service on
                  which the ordinary  shares may be listed or quoted at the time
                  of sale, including the Nasdaq National Market;

         o        In the over-the-counter market;

         o        In private transactions;

         o        Through options or other derivative instruments;

         o        By pledge to secure debts or other obligations;

         o        Through block transactions;

         o        Any other legally available means; or

         o        A combination of any of the above transactions.

         In  connection  with such sales,  the Selling  Securityholders  and any
participating broker may be deemed to be "underwriters" of the shares within the
meaning of the Securities Act, although the offering of these securities may not
be underwritten by a broker-dealer firm. If a Selling  Securityholder  qualifies
as an  "underwriter"  under the Securities Act and the rules and regulations and
interpretations  thereunder,  such  person  will be  subject  to the  prospectus
delivery  requirements of the Act. Such broker-dealers may receive  compensation
in the form of  underwriting  discounts,  concessions  or  commissions  from the
Selling Securityholders. Any such commissions and profits realized on any resale
of the shares might be deemed to be underwriting discounts and commissions under
the Securities Act. Sales in the market may be made to  broker-dealers  making a
market in the ordinary shares or other broker-dealers,  and such broker-dealers,
upon their resale of such  securities,  may be deemed to be underwriters in this
offering.

         In  addition,  any  ordinary  shares  offered by this  prospectus  that
qualify for sale pursuant to Rule 144 under the Securities Act may be sold under
Rule 144 rather than pursuant to this prospectus.

         The Company will bear all costs and expenses of the registration  under
the Securities  Act and certain state  securities  laws of the ordinary  shares,
other than any  discounts or  commissions  payable with respect to sales of such
securities.  From time to time this prospectus may be supplemented or amended as
required by the Securities  Act.  During any time when a supplement or amendment
is required, the Selling Securityholders are required to stop making sales until
the  prospectus  has been  supplemented  or  amended.  Further,  the  Company is
required to maintain the  effectiveness of the Registration  Statement until the
earlier  of (a) May 6, 2003 or (b) such time as all  securities  offered  hereby
have been sold. We will make copies of this prospectus  available to the Selling
Securityholders  and have informed the Selling  Securityholders  of the need for
delivery of a copy of this  prospectus to each purchaser of the ordinary  shares
prior to or at the time of such sale.

         Pursuant to the terms under  which the  ordinary  shares were issued to
the Selling  Securityholders,  the Company has agreed to  indemnify  the Selling
Securityholders  against such  liabilities  as they may incur as a result of any
untrue  statement  of a  material  fact in the  Registration  Statement,  or any
omission  therein  to state a material  fact  required  to be stated  therein or
necessary  in  order  to  make  the  statements   made  not   misleading.   Such
indemnification  includes  liabilities  under the Securities Act, the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), state securities laws and
the rules thereunder,  but excludes liabilities for statements or omissions that
were  based on  written  information  provided  by the  Selling  Securityholders
expressly  for  use in the  Registration  Statement,  as to  which  the  Selling
Securityholders  have  agreed to  indemnify  the  Company.  The Company has also
agreed to indemnify the Selling Securityholders against liabilities they may

                                       26




incur arising from any violation or alleged violation by the Company of the Act,
the Exchange Act, any state securities law or any rule or regulation promulgated
under the Securities Act, or the Exchange Act or any state securities law.

         Each Selling  Securityholder  and any other persons  participating in a
distribution  of  securities  will be subject to  applicable  provisions  of the
Exchange  Act and the  rules  and  regulations  thereunder,  including,  without
limitation,  Regulation M, which may restrict  certain  activities of, and limit
the timing of purchases and sales of securities by, Selling  Securityholders and
other persons participating in a distribution of securities.  Furthermore, under
Regulation M, persons  engaged in a  distribution  of securities  are prohibited
from simultaneously  engaging in market making and certain other activities with
respect  to  such  securities  for a  specified  period  of  time  prior  to the
commencement  of  such   distribution,   subject  to  specified   exceptions  or
exemptions.  All of the foregoing may affect the marketability of the securities
offered hereby.

EXPENSES ASSOCIATED WITH REGISTRATION

         We are paying  substantially  all of the  expenses of  registering  the
ordinary  shares under the Securities Act and of compliance  with blue sky laws,
including  registration  and filing  fees,  printing and  duplication  expenses,
administrative  expenses,  our legal and  accounting  fees and the legal fees of
counsel on behalf of the Selling Securityholders.  We estimate these expenses to
be approximately $ 230,158, which include the following categories of expenses:

        SEC registration fee..................................  $      158*
        Printing and engraving expenses.......................      10,000
        Legal fees and expenses...............................     100,000
        Accounting fees and expenses..........................     100,000
        Transfer agent and registrar fees and expenses........      10,000
        Miscellaneous Expenses................................      10,000

        Total.................................................  $  230,158

-------------
*This fee is being offset against the filing fee of $49,468.00  previously  paid
for Registration No. 333-31836, which was withdrawn prior to effectiveness.

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

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers or persons  controlling the
Registrant pursuant to the foregoing  provisions,  we have been informed that in
the opinion of the Securities and Exchange  Commission such  indemnification  is
against public policy as expressed in the Act and is therefore unenforceable.


                                  LEGAL MATTERS

                       ENFORCEABILITY OF CIVIL LIABILITIES

         We are  incorporated  in Israel,  and many of our directors and many of
the executive officers and the Israeli experts named herein are not residents of
the  United  States  and  substantially  all 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  or the  Israeli  experts  named  herein and
enforcement  of  judgments  obtained  in the United  States  against us, and our
directors and executive  officers,  or the Israeli experts named herein,  may be
difficult to obtain within the United  States.  Commtouch Inc. is the U.S. agent
authorized to receive service of process in any action against us 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, Naschitz, Brandes
& Co., that there is doubt as to the  enforceability  of civil liabilities under
the Securities Act or the Exchange Act in original actions instituted in Israel.
However,  subject to certain time  limitations,  an Israeli  court may declare a
foreign civil judgment enforceable if it finds that:

         *the judgment was rendered by a court which was,  according to the laws
of the state of the court, competent to render the judgment,

         *the judgment is no longer appealable,

         *the obligation imposed by the judgment is enforceable according to the
rules relating to the enforceability of judgments in Israel and the substance of
the judgment is not contrary to public policy, and

         *the judgment is executory in the state in which it was given.

         Even if the above  conditions are satisfied,  an Israeli court 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  (subject to  exceptional
cases) or if its  enforcement is likely to prejudice the sovereignty or security
of the  State of  Israel.  An  Israeli  court  also  will not  declare a foreign
judgment  enforceable if (i) the judgment was obtained by fraud,  (ii) there was
no due process,  (iii) the  judgment  was  rendered by a court not  competent to
render it according to the laws of private international law in Israel, (iv) 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 (v) 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.  Judgments rendered or
enforced  by Israeli  courts  will  generally  be  payable in Israeli  currency.
Judgment  debtors bear the risk  associated  with  converting  their awards into
foreign currency, including the risk of unfavorable exchange rates.
