purpose of updating such description.

         All documents and reports filed by the Company pursuant to Section
13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this

Item 6. Indemnification of Directors and Officers.

        Section 145 of the Delaware General Corporation Law authorizes a court

of its directors, officers, employees and other agents to the maximum extent
permitted by the Delaware General Corporation Law. The Company has also
purchased and maintained insurance for its officers, directors, employees or
agents against liabilities which an officer, a director, an employee or an agent
may incur in his capacity as such.

Item 9. Undertakings.

        The undersigned 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 the 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 to such
                      information in the Registration Statement;

        provided, however, that subparagraphs (1)(i) and (1)(ii) of this section
        do not apply if the information required to be included in a
        post-effective amendment by those subparagraphs is contained in periodic
        reports filed with or furnished to the Commission by the Registrant
        pursuant to Section 13 or Section 15(d) of the Exchange Act that are
        incorporated by reference in the Registration Statement.


                                      II-3
<PAGE>



                  (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; and

                  (3) To remove from registration by means of a post-effective
        amendment any of the securities being registered that remain unsold at
        the termination of the offering.

        The undersigned Company hereby undertakes 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 Section 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.

        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 foregoing provisions, 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. In the event that 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.

Item 6. Indemnification of Directors and Officers.

        Section 145 of the Delaware General Corporation Law authorizes a court

permitted by the Delaware General Corporation Law. The Company has also
purchased and maintained insurance for its officers, directors, employees or
agents against liabilities which an officer, a director, an employee or an agent
may incur in his capacity as such.

                                           (incorporated by reference to the Registrant's  Registration Statement on
                                           Form S-4 filed with the Commission on February 22, 2000.)

Item 9. Undertakings.

        The undersigned 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 the 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 to such
                      information in the Registration Statement;

        provided, however, that subparagraphs (1)(i) and (1)(ii) of this section
        do not apply if the information required to be included in a
        post-effective amendment by those subparagraphs is contained in periodic
        reports filed with or furnished to the Commission by the Registrant
        pursuant to Section 13 or Section 15(d) of the Exchange Act that are
        incorporated by reference in the Registration Statement.

                                      II-3
(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; and

                  (3) To remove from registration by means of a post-effective
        amendment any of the securities being registered that remain unsold at
        the termination of the offering.

        The undersigned Company hereby undertakes 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 Section 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.

        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 foregoing provisions, 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. In the event that 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.
