Company or its shareowners, (2) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (3) for willful or
negligent violation of the laws governing the payment of dividends or the

derived an improper personal benefit.

         The Delaware General Corporation Law provides for indemnification of
directors, officers, employees and agents subject to certain limitations. Our
by-laws and the appendix thereto provide for the indemnification of our
directors, officers, employees and agents to the extent permitted by Delaware
law. Our directors and officers are insured against certain liabilities for

Item 9.  Undertakings.

A.       The Company 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 this
                              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 this Registration Statement or any
                              material change to such information in this
                              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 with or furnished
         to the Commission by the Company pursuant to Section 13 or 15(d) of the
         Exchange Act that are incorporated by reference in this Registration
         Statement.

               (2)  That, for the purpose 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 to be the initial bona fide offering thereof.

                                      II-4
<PAGE>
               (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 purposes of determining any liability under the
         Securities Act, each filing of the Company's annual report pursuant to
         Section 13(a) or 15(d) of the Exchange Act 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.

B.        Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the provisions described above, or otherwise, the
Company 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. If a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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 Securities Act and will be governed by the final adjudication
of such issue.

negligent violation of the laws governing the payment of dividends or the

         The Delaware General Corporation Law provides for indemnification of
directors, officers, employees and agents subject to certain limitations. Our

directors, officers, employees and agents to the extent permitted by Delaware
law. Our directors and officers are insured against certain liabilities for

Item 9.  Undertakings.

A.       The Company 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 this
                              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 this Registration Statement or any
                              material change to such information in this
                              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 with or furnished
         to the Commission by the Company pursuant to Section 13 or 15(d) of the
         Exchange Act that are incorporated by reference in this Registration
         Statement.

               (2)  That, for the purpose 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 to be the initial bona fide offering thereof.

                                      II-4
(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 purposes of determining any liability under the
         Securities Act, each filing of the Company's annual report pursuant to
         Section 13(a) or 15(d) of the Exchange Act 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.

B.        Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the provisions described above, or otherwise, the
Company 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. If a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company 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
Company 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 Securities Act and will be governed by the final adjudication
of such issue.

                                      II-5
