                      To Be Incorporated By Reference Into
                      Registration Statements on Forms S-8
     (File Nos. 2-77590, 2-95258, 033-00661, 33-51257, 033-63859, 333-09851,
                      333-48423, 333-54560 and 333-105527)


                                  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:

                    (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.

          (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)  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.

(h)  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.
