Item 9.  Undertakings.
         -------------

       (a)  The undersigned registrant hereby undertakes:

           (1) To file, during any period in which offers or sales are being
made of the securities registered hereby, 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
       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; provided, however, that the undertakings set forth in
       paragraphs (i) and (ii) above do not apply if the information required to
       be included in a post-effective amendment by those paragraphs is
       contained in periodic reports filed by the registrant with the Securities
       Exchange Commission or furnished to the Commission pursuant to Section 13
       or Section 15(d) of the Securities Exchange Act of 1934 that are
       incorporated by reference in this

                                      S-3
   4

       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 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, where applicable, each filing
of an employee benefit plans annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
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) 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.

       (d) The undersigned registrant hereby further undertakes that the
registrant will submit or has submitted the Plan and any amendment thereto to
the Internal Revenue Service ("IRS") in a timely manner and the registrant will
make or has made all changes required by the IRS in order to qualify the Plan.

                                   SIGNATURES

       Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Dayton, State of Ohio, on this 26th day of October,
1999.
