Item 6. Indemnification of Directors and Officers

     In  general,  the  Wisconsin  Business  Corporation  Law  provides  that  a
corporation shall indemnify  directors and officers for all reasonable  expenses
incurred  in  connection  with the  successful  defense  of  actions  arising in
connection with their service as directors and officers of the  corporation.  In
proceedings  in which the director or officer is not  successful  in the defense
thereof,  the  Wisconsin  Business  Corporation  Law provides that a corporation
shall indemnify a director or officer against  liability  unless the director or
officer  breached or failed to perform a duty owed to the  corporation  and such
breach or failure meets certain  specified  criteria  constituting,  in general,
some act of misconduct.  The Wisconsin  Business  Corporation  Law  specifically
states that it is the policy of Wisconsin  to require or permit  indemnification
in connection with a proceeding  involving securities  regulation,  as described
therein,  to the extent  required or permitted as described  above. In addition,
the  corporation  may  reimburse  a director  or  officer  for his  expenses  in
defending  against actions as they are incurred upon the director's or officer's
written  request  accompanied by a written  affirmation of his good faith belief
that he has not breached or failed to perform his duties to the  corporation and
a written  undertaking to repay amounts advanced if it is ultimately  determined
that  indemnification is not required under the Wisconsin  Business  Corporation
Law. A court of law may order that the corporation provide  indemnification to a
director or officer if the court finds that the  director or officer is entitled
thereto under the  applicable  statutory  provision or is fairly and  reasonably
entitled thereto in view of all the relevant circumstances,  whether or not such
indemnification is required under the applicable statutory provision.

     The  Wisconsin  Business   Corporation  Law  specifies  various  procedures
pursuant  to  which  a  director  or  officer   may   establish   his  right  to
indemnification.

     Provided that it is not determined by or on behalf of the corporation  that
the  director  or  officer  breached  or  failed  to  perform a duty owed to the
corporation  and  such  breach  or  failure  meets  certain  specified  criteria
constituting,  in general,  some act of misconduct,  a Wisconsin corporation may
provide additional rights to indemnification under its articles of incorporation
or by-laws, by written agreement,  by resolution of its board of directors or by
a vote of the holders of a majority of its outstanding shares.

     The  Registrant's  By-laws provide for  indemnification  and advancement of
expenses  of  directors  and  officers  to the  fullest  extent  provided by the
Wisconsin  Business Law. This  provision is not exclusive of any other rights to
indemnification  or the  advancement  of expenses to which a director or officer
may be entitled under any written  agreement,  resolution of directors,  vote of
shareholders,  by  law  or  otherwise.  The  general  effect  of  the  foregoing
provisions may be to reduce the  circumstances  which an officer or director may
be  required  to bear the  economic  burden  of the  foregoing  liabilities  and
expenses.

Item 7. Exemption from Registration Claimed

     Not applicable.

Item 8. Exhibits

     See Exhibit Index.

Item 9. Undertakings

     (a)  Rule 415 Offering

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;

               (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 material change to such  information in the
                    registration statement.

                    Provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii)
                    of this section 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 16(d) of the  Securities  Exchange Act
                    of  1934  that  are   incorporated   by   reference  in  the
                    registration statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933,  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) Incorporating Subsequent Exchange Act Documents by Reference

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  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)  Indemnification  for  Liabilities  arising under the Securities Act of
          1933

     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 Commission such  indemnification  is
against  public  policy  as  expressed  in the  Securities  Act of 1933  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 of 1933 and will be governed by the
final adjudication of such issue.

Item 6. Indemnification of Directors and Officers

     In  general,  the  Wisconsin  Business  Corporation  Law  provides  that  a
corporation shall indemnify  directors and officers for all reasonable  expenses
incurred  in  connection  with the  successful  defense  of  actions  arising in
connection with their service as directors and officers of the  corporation.  In
proceedings  in which the director or officer is not  successful  in the defense
thereof,  the  Wisconsin  Business  Corporation  Law provides that a corporation
shall indemnify a director or officer against  liability  unless the director or
officer  breached or failed to perform a duty owed to the  corporation  and such
breach or failure meets certain  specified  criteria  constituting,  in general,
some act of misconduct.  The Wisconsin  Business  Corporation  Law  specifically
states that it is the policy of Wisconsin  to require or permit  indemnification
in connection with a proceeding  involving securities  regulation,  as described
therein,  to the extent  required or permitted as described  above. In addition,
the  corporation  may  reimburse  a director  or  officer  for his  expenses  in
defending  against actions as they are incurred upon the director's or officer's
written  request  accompanied by a written  affirmation of his good faith belief
that he has not breached or failed to perform his duties to the  corporation and
a written  undertaking to repay amounts advanced if it is ultimately  determined
that  indemnification is not required under the Wisconsin  Business  Corporation
Law. A court of law may order that the corporation provide  indemnification to a
director or officer if the court finds that the  director or officer is entitled
thereto under the  applicable  statutory  provision or is fairly and  reasonably
entitled thereto in view of all the relevant circumstances,  whether or not such
indemnification is required under the applicable statutory provision.

     The  Wisconsin  Business   Corporation  Law  specifies  various  procedures
pursuant  to  which  a  director  or  officer   may   establish   his  right  to
indemnification.

     Provided that it is not determined by or on behalf of the corporation  that
the  director  or  officer  breached  or  failed  to  perform a duty owed to the
corporation  and  such  breach  or  failure  meets  certain  specified  criteria
constituting,  in general,  some act of misconduct,  a Wisconsin corporation may
provide additional rights to indemnification under its articles of incorporation
or by-laws, by written agreement,  by resolution of its board of directors or by
a vote of the holders of a majority of its outstanding shares.

     The  Registrant's  By-laws provide for  indemnification  and advancement of
expenses  of  directors  and  officers  to the  fullest  extent  provided by the
Wisconsin  Business Law. This  provision is not exclusive of any other rights to
indemnification  or the  advancement  of expenses to which a director or officer
may be entitled under any written  agreement,  resolution of directors,  vote of
shareholders,  by  law  or  otherwise.  The  general  effect  of  the  foregoing
provisions may be to reduce the  circumstances  which an officer or director may
be  required  to bear the  economic  burden  of the  foregoing  liabilities  and
expenses.

Item 7. Exemption from Registration Claimed

     Not applicable.

Item 8. Exhibits

     See Exhibit Index.

Item 9. Undertakings

     (a)  Rule 415 Offering

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;

               (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 material change to such  information in the
                    registration statement.

                    Provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii)
                    of this section 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 16(d) of the  Securities  Exchange Act
                    of  1934  that  are   incorporated   by   reference  in  the
                    registration statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933,  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) Incorporating Subsequent Exchange Act Documents by Reference

     The  undersigned   registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  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)  Indemnification  for  Liabilities  arising under the Securities Act of
          1933

     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 Commission such  indemnification  is
against  public  policy  as  expressed  in the  Securities  Act of 1933  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 of 1933 and will be governed by the
final adjudication of such issue.

requirements  for  filing  on Form S-8 and had  duly  caused  this  Registration
