* Payable only upon exercise of the warrant.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Articles of Association provide that the Registrant will indemnify any Office Holder of the Registrant as defined in the Companies Ordinance out of the assets of the Registrant against all liabilities incurred bona fide by such Office Holder in the line of his duties for the Registrant or related thereto. The Registration Rights Agreement which we entered into with Go2Net and Vulcan (filed as an exhibit to this registration statement) contains certain provisions relating to the indemnification of our directors and officers.

In addition, the Registrant maintains insurance for its directors and officers. Israeli law permits a company to insure an Office Holder 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 insurance policies in the amount of US$25 million covering its directors and officers.

Certain members of our management team are officers of our 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.

II-1


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 in connection with the proceeding.

Pursuant to the terms under which the ordinary shares and the warrant were issued to the Selling Securityholders, the Company has agreed to indemnify the Selling Securityholders and any underwriter against such liabilities as they may incur as a result of any untrue statement of a material fact in the Registration Statement of which this prospectus is a part, or any omission herein or therein to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading. Such indemnification includes liabilities under the Securities Act, the Exchange Act, state securities laws and the rules thereunder, but excludes liabilities for statements or omissions that were based on information provided by Go2Net or Vulcan Ventures, as to which the Selling Securityholders have agreed to indemnify the Company and any underwriter. The Company has also agreed indemnify the Selling Securityholders against withholding tax, tax on capital gains, dividends or other income, any transfer tax, stamp duty or similar tax, or any other form of tax, assessment or imposition imposed by the State of Israel with respect to their acquisition and subsequent sale of the ordinary shares and the warrant as well as certain other matters, including the requirement to pay additional amounts to reimburse the Selling Securityholders for any U.S. taxes on the amount of such indemnity.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

Since December 1996, we have sold and issued the securities listed below without registering the securities under the Securities Act of 1933, as amended. None of these transactions involved any underwriters, underwriting discounts or commissions, or any public offering.((a))

(1) Between July 1997 and March 1999, we issued and sold for cash 153,093 Series C Convertible Preferred Shares at a price of $72.17 per share to 22 investors.

(2) In April 1999, we issued Convertible Promissory Notes that have since converted into 42,081 Series D Convertible Preferred Shares. The effective price for each Series D Preferred Share was $314.56.

(3) Concurrently with our initial public offering on July 16, 1999, in a private transaction we sold 896,057 ordinary shares to Go2Net for a purchase price of $13,333,328 and an additional 448,029 shares to Vulcan Ventures Incorporated for a purchase price of $6,666,672. The purchase price per share was $14.88, equal to the initial public offering price less the


(a)Share figures and price-per-share figures do not reflect the twenty-for-one stock split which became effective concurrently with the initial public offering.


II-2


underwriting discount. In addition, we issued a warrant to Go2Net to purchase 1,136,000 ordinary shares at an exercise price of $12.80 per share.

(4) In connection with an E-mail Services Agreement dated October 27, 1999 between Commtouch's U.S. subsidiary Commtouch Software, Inc., and Microsoft Corporation, Commtouch granted Microsoft a warrant, exercisable until December 29, 1999, to purchase 707,964 of Commtouch's ordinary shares at an exercise price of $28.25 per share for an aggregate exercise price of $20,000,000. On December 29, 1999, Microsoft exercised the warrant and now holds 707,965 shares.

We believe that each transaction listed above was exempt from the registration requirements of the Securities Act of 1933, as amended, by virtue of Section 4(2) of the Securities Act, Regulation D, promulgated under the Securities Act or Rule 701 with respect to compensatory benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of securities in each such transaction represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the share certificates and warrants issued in such transactions. All recipients had adequate access, through their relationships with us, to information about us.

Schedule II

ITEM 17. 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;

(iii) to include any material information with respect to the Plan of Distribution not previously disclosed in the Registration Statement or any other material change to such information in the Registration Statement.

II-4


Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 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 1933 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.

(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.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Rule 3-19 of this chapter at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided that the Registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Rule 3-19 of this chapter if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act that are incorporated by reference in the Form F-3.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than 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.

II-5
