ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

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
purchase or redemption of stock or (4) for any transaction from which a director
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
actions taken in such capacities, including liabilities under the Securities
Act.

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 paragraphs (1)(i) and (1)(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
            with or furnished to the Commission by the Company pursuant to
            Section 13 or Section 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.

            (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.


                                       5


<PAGE>   6

            (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.

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
purchase or redemption of stock or (4) for any transaction from which a director
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 paragraphs (1)(i) and (1)(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
            with or furnished to the Commission by the Company pursuant to
            Section 13 or Section 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.

            (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.

                                       5
6

            (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.
