ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

           Israeli law permits a company to insure an Office Holder (generally,
a director or executive officer) in respect of liabilities incurred by him as a
result of the breach of his duty of care to the company or to another person, or
as a result of the breach of his fiduciary duty to the company, to the extent
that he acted in good faith and had reasonable cause to believe that the act
would not prejudice the company. A company can also insure an Office Holder for
monetary liabilities as a result of an act or omission that he committed in
connection with his serving as an Office Holder. Moreover, a company can
indemnify an Office Holder for monetary liability in connection with his
activities as an Office Holder. The Articles of Association of the Registrant
allow the Registrant to insure and indemnify Office Holders to the fullest
extent permitted by law. Pursuant to these provisions, the Registrant has in
effect as of January 7, 2000 insurance policies in the amount of US$25 million
covering its directors and officers.

           Reference is made to Section 6 of the Underwriting Agreement, a copy
of which is filed as Exhibit 1.1 to the Registrant's prospectus, which provides
for indemnification of the directors and officers of the Registrant who sign the
Registration Statement by the Underwriters against certain liabilities,
including those arising under the Securities Act, in certain circumstances.

           Certain members of the Registrant's management team are officers of
the Registrant's subsidiary, CommTouch Software, Inc., a California corporation,
or reside in California. The Articles of Incorporation of CommTouch Software,
Inc. provide that the liability of the directors of the corporation for monetary
damages shall be eliminated to the fullest extent permissible under California
law and that the corporation is authorized to provide for the indemnification of
agents of the corporation, as defined in Section 317 of the California General
Corporation Law, in excess of that expressly permitted by Section 317 for breach
of duty to the corporation and its shareholders to the fullest extent
permissible under California law.

           With respect to all proceedings other than shareholder derivative
actions, Section 317 permits a California corporation to indemnify any of its
directors, officers or other agents only if such person acted in good faith and
in a manner such person reasonably believed to be in the best interests of the
corporation and, in the case of a criminal proceeding, had no reasonable cause
to believe the conduct of such person was unlawful. In the case of derivative
actions, a California corporation may indemnify any of its directors, officers
or agents only if such person acted in good faith and in a manner such person
believed to be in the best interests of the corporation and its shareholders.
Furthermore, in derivative actions, no indemnification is permitted (i) with
respect to any matter with respect to which the person to be indemnified has
been held liable to the corporation, unless such indemnification is approved by
the court; (ii) of amounts paid in settling or otherwise disposing of a pending
action without court approval; or (iii) of expenses incurred in defending a
pending action which is settled or otherwise disposed of without court approval.
To the extent that a director, officer or agent of a corporation has been
successful on the merits in defense of any proceeding for which indemnification
is permitted by Section 317, a corporation is obligated by Section 317 to
indemnify such person against expenses actually and reasonably incurred by him
in connection with the proceeding.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 8. EXHIBITS.

           See Index to Exhibits.

ITEM 9. UNDERTAKINGS.

           (a) The undersigned Registrant hereby undertakes:

                      (1) To file, during any period in which offers or sales
           are being made, a post-effective amendment to this registration
           statement;

                                 (i) To include any prospectus required by
                      Section 10(a)(3) of the Securities Act;

                                 (ii) To reflect in the prospectus any facts or
                      events arising after the effective date of the
                      registration statement (or the most recent post-effective
                      amendment thereof) which, individually or in the
                      aggregate, represent a fundamental change in the
                      information set forth in the registration statement.
                      Notwithstanding the foregoing, any increase or decrease in
                      volume of securities offered (if the total dollar value of
                      securities offered would not exceed that which was
                      registered) and any deviation from the low or high and of
                      the estimated maximum offering range may be reflected in
                      the form of prospectus filed with the Commission pursuant
                      to Rule 424(b) if, in the aggregate, the changes in volume
                      and price represent no more than 20 percent change in the
                      maximum aggregate offering price set forth in the
                      "Calculation of Registration Fee" table in the effective
                      registration statement;

                                 (iii) To include any material information with
                      respect to the plan of distribution not previously
                      disclosed in the registration statement or any material
                      change to such information in the registration statement;

           provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
           the registration statement is on Form S-3, Form S-8 or Form F-3, and
           the information required to be included in a post-effective amendment
           by those paragraphs is contained in periodic reports filed by the
           Registrant pursuant to Section 13 or 15(d) of the Exchange Act that
           are incorporated by reference in the registration statement.

                      (2) That, for the purpose of determining any liability
           under the Securities Act, each such post-effective amendment shall be
           deemed to be a new registration statement relating to the securities
           offered therein, and the offering of such securities at that time
           shall be deemed to be the initial bona fide offering thereof.

   6

                      (3) To remove from registration by means of a
           post-effective amendment any of the securities being registered which
           remain unsold at the termination of the offering.

           (b) The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

           (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the provisions described in Item 6, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
