Item 6.  Indemnification of Directors and Officers.

Indemnification of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, indemnify an office holder for any of the following
liabilities or expenses that they may incur due to an act performed or failure
to act in his or her capacity as the company's office holder:

          o    monetary  liability  imposed on the  office  holder in favor of a
               third party in a judgment,  including a settlement or an arbitral
               award confirmed by a court;

          o    reasonable legal costs, including attorneys' fees, expended by an
               office  holder  as a result  of an  investigation  or  proceeding
               instituted  against the office  holder by a competent  authority,
               provided that such investigation or proceeding  concludes without
               the filing of an indictment against the office holder and either:
               no financial  liability  was imposed on the office holder in lieu
               of criminal proceedings, or a financial liability was

                                        3



<PAGE>


               imposed on the office holder in lieu of criminal proceedings with
               respect  to an alleged  criminal  offense  that does not  require
               proof of criminal intent; and

          o    reasonable legal costs,  including  attorneys' fees,  expended by
               the office  holder or for which the office holder is charged by a
               court:

               o    in an  action  brought  against  the  office  holder  by the
                    company,  on behalf of the  company  or on behalf of a third
                    party,

               o    in a  criminal  action  from  which  the  office  holder  is
                    acquitted, or

               o    in a criminal action in which the office holder is convicted
                    of a  criminal  offense  which  does  not  require  proof of
                    criminal intent.

         A company may indemnify an office holder in respect of these
liabilities either in advance of an event or following an event. If a company
undertakes to indemnify an office holder in advance of an event, the
indemnification, other than legal costs, must be limited to foreseeable events
in light of the company's actual activities when the company undertook such
indemnification, and reasonable amounts or standards, as determined by the board
of directors.

Insurance of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, obtain insurance for an office holder against
liabilities incurred in his or her capacity as an office holder. These
liabilities include a breach of duty of care to the company or a third-party, a
breach of duty of loyalty and any monetary liability imposed on the office
holder in favor of a third-party.

Exculpation of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, exculpate an office holder from a breach of duty of
care in advance of that breach. Our articles of association provide for
exculpation both in advance or retroactively, to the extent permitted under
Israeli law. A company may not exculpate an office holder from a breach of duty
of loyalty towards the company or from a breach of duty of care concerning
dividend distribution or a purchase of the company's shares by the company or
other entities controlled by the company.

Limitations on Exculpation, Insurance and Indemnification

         Under the Israeli Companies Law, a company may indemnify or insure an
office holder against a breach of duty of loyalty only to the extent that the
office holder acted in good faith and had reasonable grounds to assume that the
action would not prejudice the company. In addition, a company may not
indemnify, insure or exculpate an office holder against a breach of duty of care
if committed intentionally or recklessly (excluding mere negligence), or
committed with the intent to derive an unlawful personal gain, or for a fine or
forfeit levied against the office holder in connection with a criminal offense.

         Pursuant to the Israeli Companies Law, exculpation of, procurement of
insurance coverage for, and an undertaking to indemnify or indemnification of,
our office holders must be approved by our audit committee and our board of
directors and, if the office holder is a director, also by our shareholders.

         Our Articles of Association allow us to insure, indemnify and exempt
our office holders to the fullest extent permitted by law, subject to the
provisions of the Israeli Companies Law. On January 18, 2000, our shareholders
agreed to indemnify our office holders to the fullest extent permitted under the
Israeli Companies Law. At our 2007 annual general meeting of shareholders, our
shareholders approved a new form of indemnification agreement, which indemnifies
the office holders to the fullest extent permitted under the Israeli Companies
Law as currently in effect. We have obtained directors and officers liability
insurance for the benefit of our office holders.

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");

                           (ii) To reflect in the prospectus any facts or events
                           arising after the effective date of this 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;




                                        5



<PAGE>

                           (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 (a)(1)(i) and
                  (a)(1)(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.

         Not applicable.

Item 5.  Interests of Named Experts and Counsel.

         Not applicable.

Item 6.  Indemnification of Directors and Officers.

Indemnification of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, indemnify an office holder for any of the following
liabilities or expenses that they may incur due to an act performed or failure
to act in his or her capacity as the company's office holder:

          o    monetary  liability  imposed on the  office  holder in favor of a
               third party in a judgment,  including a settlement or an arbitral
               award confirmed by a court;

          o    reasonable legal costs, including attorneys' fees, expended by an
               office  holder  as a result  of an  investigation  or  proceeding
               instituted  against the office  holder by a competent  authority,
               provided that such investigation or proceeding  concludes without
               the filing of an indictment against the office holder and either:
               no financial  liability  was imposed on the office holder in lieu
               of criminal proceedings, or a financial liability was

                                        3
imposed on the office holder in lieu of criminal proceedings with
               respect  to an alleged  criminal  offense  that does not  require
               proof of criminal intent; and

          o    reasonable legal costs,  including  attorneys' fees,  expended by
               the office  holder or for which the office holder is charged by a
               court:

               o    in an  action  brought  against  the  office  holder  by the
                    company,  on behalf of the  company  or on behalf of a third
                    party,

               o    in a  criminal  action  from  which  the  office  holder  is
                    acquitted, or

               o    in a criminal action in which the office holder is convicted
                    of a  criminal  offense  which  does  not  require  proof of
                    criminal intent.

         A company may indemnify an office holder in respect of these
liabilities either in advance of an event or following an event. If a company
undertakes to indemnify an office holder in advance of an event, the
indemnification, other than legal costs, must be limited to foreseeable events
in light of the company's actual activities when the company undertook such
indemnification, and reasonable amounts or standards, as determined by the board
of directors.

Insurance of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, obtain insurance for an office holder against
liabilities incurred in his or her capacity as an office holder. These
liabilities include a breach of duty of care to the company or a third-party, a
breach of duty of loyalty and any monetary liability imposed on the office
holder in favor of a third-party.

Exculpation of Office Holders

         Under the Israeli Companies Law, a company may, if permitted by its
articles of association, exculpate an office holder from a breach of duty of
care in advance of that breach. Our articles of association provide for
exculpation both in advance or retroactively, to the extent permitted under
Israeli law. A company may not exculpate an office holder from a breach of duty
of loyalty towards the company or from a breach of duty of care concerning
dividend distribution or a purchase of the company's shares by the company or
other entities controlled by the company.

Limitations on Exculpation, Insurance and Indemnification

         Under the Israeli Companies Law, a company may indemnify or insure an
office holder against a breach of duty of loyalty only to the extent that the
office holder acted in good faith and had reasonable grounds to assume that the
action would not prejudice the company. In addition, a company may not
indemnify, insure or exculpate an office holder against a breach of duty of care
if committed intentionally or recklessly (excluding mere negligence), or
committed with the intent to derive an unlawful personal gain, or for a fine or
forfeit levied against the office holder in connection with a criminal offense.

         Pursuant to the Israeli Companies Law, exculpation of, procurement of
insurance coverage for, and an undertaking to indemnify or indemnification of,
our office holders must be approved by our audit committee and our board of
directors and, if the office holder is a director, also by our shareholders.

         Our Articles of Association allow us to insure, indemnify and exempt
our office holders to the fullest extent permitted by law, subject to the
provisions of the Israeli Companies Law. On January 18, 2000, our shareholders
agreed to indemnify our office holders to the fullest extent permitted under the
Israeli Companies Law. At our 2007 annual general meeting of shareholders, our
shareholders approved a new form of indemnification agreement, which indemnifies
the office holders to the fullest extent permitted under the Israeli Companies
Law as currently in effect. We have obtained directors and officers liability
insurance for the benefit of our office holders.

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");

                           (ii) To reflect in the prospectus any facts or events
                           arising after the effective date of this 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;

                                        5
(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 (a)(1)(i) and
                  (a)(1)(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.

                                        6
