                                OTHER INFORMATION



Item 15.  Indemnification.  Insofar as  indemnification for  liabilities arising
          under the  Securities  Act of 1933,  as amended,  may be  permitted to
          directors, officers and controlling persons of the Registrant pursuant
          to the Articles of  Incorporation,  the  By-Laws,  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 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
          shares 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 is against public policy as expressed in the Act
          and will be governed by the final adjudication of such issue.
