ITEM 9.   UNDERTAKINGS

          The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a posteffective amendment to this Registration Statement:

                 (i)     To include any prospectus required by Section 10(a)(3)
          of the Securities Act of 1933, unless the information required to be
          included in such posteffective amendment is contained in a periodic
          report filed by Registrant pursuant to Section 13 or Section 15(d)
          of the Securities Exchange Act of 1934 and incorporated herein by
          reference;

                (ii)     To reflect in the prospectus any facts or events
          arising after the effective date of the Registration Statement (or the
          most recent posteffective amendment thereof) which, individually or in
          the aggregate, represent a fundamental change in the information set
          forth in this Registration Statement, unless the information
          required to be included in such posteffective amendment is contained
          in a periodic report filed by Registrant pursuant to Section 13 or
          Section 15(d) of the Securities Exchange Act of 1934 and
          incorporated herein by reference;

               (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;
 
          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such posteffective 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.

                                      S-2<PAGE>
<PAGE>
          (3)  To remove from registration by means of a posteffective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby further 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 each filing of the annual
report of the Plan 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.

          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.

ITEM 9.   UNDERTAKINGS

          The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a posteffective amendment to this Registration Statement:

                 (i)     To include any prospectus required by Section 10(a)(3)
          of the Securities Act of 1933, unless the information required to be
          included in such posteffective amendment is contained in a periodic
          report filed by Registrant pursuant to Section 13 or Section 15(d)
          of the Securities Exchange Act of 1934 and incorporated herein by
          reference;

                (ii)     To reflect in the prospectus any facts or events
          arising after the effective date of the Registration Statement (or the
          most recent posteffective amendment thereof) which, individually or in
          the aggregate, represent a fundamental change in the information set
          forth in this Registration Statement, unless the information
          required to be included in such posteffective amendment is contained
          in a periodic report filed by Registrant pursuant to Section 13 or
          Section 15(d) of the Securities Exchange Act of 1934 and
          incorporated herein by reference;

               (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;
 
          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such posteffective 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.

                                      S-2
(3)  To remove from registration by means of a posteffective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby further 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 each filing of the annual
report of the Plan 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.

          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.

                                      S-3
