Item 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Under the Israeli Companies Law, an Israeli company may not exempt an

                                       4

Office Holder Insurance

      The Registrant's Articles of Association provide that, subject to the
provisions of the Israeli Companies Law, the Registrant may enter into a
contract for the insurance of the liability of any of its office holders with
respect to:

      o    a breach of his duty of care to the Registrant or to another person;

      o    a breach of his duty of loyalty to the Registrant, provided
           that the office holder acted in good faith and had reasonable
           cause to assume that his act would not prejudice the
           Registrant's interests; or

      o    a financial liability imposed upon him in favor of another
           person concerning an act performed by him in his capacity as
           an office holder.

Indemnification of Office Holders

      The Registrant's Articles of Association provide that it may indemnify
an office holder against:

      o    a financial liability imposed on him in favor of another
           person by any judgment, including a settlement or an
           arbitrator's award approved by a court concerning an act
           performed in his capacity as an office holder; and

      o    reasonable litigation expenses, including attorneys' fees,
           expended by the office holder or charged to him by a court, in
           proceedings instituted against him by the Registrant or
           instituted on its behalf or by another person, or in a
           criminal charge from which he was acquitted, or a criminal
           charge in which he was convicted for a criminal offense that
           does not require proof of intent, in each case relating to an
           act performed in his capacity as an office holder.

      The Registrant's Articles of Association also include the following:

      o    The Registrant is authorized to grant in advance an
           undertaking to indemnify an office holder, provided that the
           undertaking is limited to specified events which the Board of
           Directors deems to be anticipated and limited in amount
           determined by the Board of Directors to be reasonable under
           the circumstances.

      o    The Registrant is authorized to indemnify retroactively an office
           holder.

Limitations on Insurance and Indemnification

      The Israeli Companies Law provides that a company may not indemnify an
office holder, nor exculpate an office holder, nor enter into an insurance
contract which would provide coverage for any monetary liability incurred as a
result of any of the following:


                                       5
<PAGE>

      o    a breach by the office holder of his duty of loyalty unless,
           with respect to insurance coverage, the office holder acted in
           good faith and had a reasonable basis to believe that the act
           would not prejudice the company;

      o    a breach by the office holder of his duty of care if the breach was
           done intentionally or recklessly;

      o    any act or omission done with the intent to derive an illegal
           personal benefit; or

      o    any fine levied against the office holder.

      In addition, under the Israeli Companies Law, undertaking to indemnify
or indemnification of, exculpation of, and procurement of insurance coverage
for, the Registrant's office holders must be approved by its audit committee and
board of directors and, in specified circumstances, by its shareholders.

      The Registrant has indemnified its office holders to the fullest extent
permitted by law. The Registrant currently maintain a directors and officers
liability insurance policy with a per claim and aggregate coverage limit of
$15.0 million.

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 of 1933, as amended
                           (the "Securities Act");

                                       6
<PAGE>

                           (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 hereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in this Registration Statement;
                           and

                           (iii) To include any material information with
                           respect to the plan of distribution not previously
                           disclosed in this Registration Statement or any
                           material change to such information in this
                           Registration Statement.

                           provided, however, that paragraphs (l)(i) and (l)(ii)
                  above 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 this
                  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.

                  (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 that is incorporated by reference in this 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 foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the 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.

Item 5.           INTEREST OF NAMED EXPERTS AND COUNSEL

         Not applicable.

Item 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Under the Israeli Companies Law, an Israeli company may not exempt an
office holder from liability with respect to a breach of his duty of loyalty,
but may exempt in advance an office holder from his liability to the company, in
whole or in part, with respect to a breach of his duty of care.

                                       4
Office Holder Insurance

      The Registrant's Articles of Association provide that, subject to the
provisions of the Israeli Companies Law, the Registrant may enter into a
contract for the insurance of the liability of any of its office holders with
respect to:

      o    a breach of his duty of care to the Registrant or to another person;

      o    a breach of his duty of loyalty to the Registrant, provided
           that the office holder acted in good faith and had reasonable
           cause to assume that his act would not prejudice the
           Registrant's interests; or

      o    a financial liability imposed upon him in favor of another
           person concerning an act performed by him in his capacity as
           an office holder.

Indemnification of Office Holders

      The Registrant's Articles of Association provide that it may indemnify
an office holder against:

      o    a financial liability imposed on him in favor of another
           person by any judgment, including a settlement or an
           arbitrator's award approved by a court concerning an act
           performed in his capacity as an office holder; and

      o    reasonable litigation expenses, including attorneys' fees,
           expended by the office holder or charged to him by a court, in
           proceedings instituted against him by the Registrant or
           instituted on its behalf or by another person, or in a
           criminal charge from which he was acquitted, or a criminal
           charge in which he was convicted for a criminal offense that
           does not require proof of intent, in each case relating to an
           act performed in his capacity as an office holder.

      The Registrant's Articles of Association also include the following:

      o    The Registrant is authorized to grant in advance an
           undertaking to indemnify an office holder, provided that the
           undertaking is limited to specified events which the Board of
           Directors deems to be anticipated and limited in amount
           determined by the Board of Directors to be reasonable under
           the circumstances.

      o    The Registrant is authorized to indemnify retroactively an office
           holder.

Limitations on Insurance and Indemnification

      The Israeli Companies Law provides that a company may not indemnify an
office holder, nor exculpate an office holder, nor enter into an insurance
contract which would provide coverage for any monetary liability incurred as a
result of any of the following:

                                       5
o    a breach by the office holder of his duty of loyalty unless,
           with respect to insurance coverage, the office holder acted in
           good faith and had a reasonable basis to believe that the act
           would not prejudice the company;

      o    a breach by the office holder of his duty of care if the breach was
           done intentionally or recklessly;

      o    any act or omission done with the intent to derive an illegal
           personal benefit; or

      o    any fine levied against the office holder.

      In addition, under the Israeli Companies Law, undertaking to indemnify
or indemnification of, exculpation of, and procurement of insurance coverage
for, the Registrant's office holders must be approved by its audit committee and
board of directors and, in specified circumstances, by its shareholders.

      The Registrant has indemnified its office holders to the fullest extent
permitted by law. The Registrant currently maintain a directors and officers
liability insurance policy with a per claim and aggregate coverage limit of
$15.0 million.

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 of 1933, as amended
                           (the "Securities Act");

                                       6
(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 hereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in this Registration Statement;
                           and

                           (iii) To include any material information with
                           respect to the plan of distribution not previously
                           disclosed in this Registration Statement or any
                           material change to such information in this
                           Registration Statement.

                           provided, however, that paragraphs (l)(i) and (l)(ii)
                  above 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 this
                  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.

                  (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 that is incorporated by reference in this 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 foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the 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.

                                       7
