                         S-1, filed on August 6, 1997)

Item 9.     Undertakings
------

       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 (i) to include
any prospectus required by Section 10(a)(3) of the Securities Act, (ii) to
reflect in the prospectus any facts or events arising after the effective date
of the Registration Statement (or most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental
change in the information set forth in the Registration Statement, and (iii)
to include any material information with respect to the plan of distribution
not previously disclosed in the Registration Statement or any material change
in such information in the Registration Statement; provided, however, that
clauses (i) and (ii) do not apply if the information required to be included
in a post-effective amendment by those clauses is contained in periodic
reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.

       2.   That, for the purposes of determining any liability under the
Securities Act, 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 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.

       4.   That, for the purposes of determining any liability under the
Securities Act, each filing of the Registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by
reference in the Registration Statement shall be deemed to a new registration
statement relating to the securities offered therein, and that offering of
such securities at that time shall be deemed to be the initial bona fide
offering thereof.

       5.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officer and controlling
persons of the registrant pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for
indemnification against liabilities (other than the payment by 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 questions whether such indemnification by it is
against public policy expressed in the Securities Act will and will be
governed by the final adjudication of such issue.

       99.1              Profit Sharing 401(k) Plan (incorporated by reference 
                         herein as Exhibit 10.4 to Amendment No. 1 to Form     
                         S-1, filed on August 6, 1997)

Item 9.     Undertakings
------

       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 (i) to include
any prospectus required by Section 10(a)(3) of the Securities Act, (ii) to
reflect in the prospectus any facts or events arising after the effective date
of the Registration Statement (or most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental
change in the information set forth in the Registration Statement, and (iii)
to include any material information with respect to the plan of distribution
not previously disclosed in the Registration Statement or any material change
in such information in the Registration Statement; provided, however, that
clauses (i) and (ii) do not apply if the information required to be included
in a post-effective amendment by those clauses is contained in periodic
reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in the Registration Statement.

       2.   That, for the purposes of determining any liability under the
Securities Act, 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 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.

       4.   That, for the purposes of determining any liability under the
Securities Act, each filing of the Registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by
reference in the Registration Statement shall be deemed to a new registration
statement relating to the securities offered therein, and that offering of
such securities at that time shall be deemed to be the initial bona fide
offering thereof.

       5.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officer and controlling
persons of the registrant pursuant to the foregoing provisions or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for
indemnification against liabilities (other than the payment by 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 questions whether such indemnification by it is
against public policy expressed in the Securities Act will and will be
governed by the final adjudication of such issue.
