Exhibit 99.1


FORM S-8 UNDERTAKING


     The following is incorporated by reference in Item 21 of Part II of
the registrant's registration statements on Form S-8:
           
          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 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 Act and will be governed by the final adjudication of such
          issue.
