provided, however, that the documents enumerated above or subsequently filed by

so modified or superseded shall not be deemed, except as so modified or
superseded, to constitute a part of this registration statement.

Item 4. Description of Securities.

Item 5. Interest of Named Experts and Counsel.
        ------------------------------------

        Not applicable.

Item 6. Indemnification of Directors and Officers.
        -----------------------------------------

     Certain provisions of the General Corporation Law of the State of Delaware
provide that the Company may indemnify the directors and officers of the Company
and affiliated companies against liabilities and expenses incurred by reason of
the fact that such persons were serving in such capacities, subject to certain
limitations and conditions set forth in the statute. The Amended and Restated
Certificate of Incorporation and By-laws of the Company provides that the
Company shall indemnify its directors and officers to the fullest extent
permitted by Delaware law.

     In addition, all of the Company's directors and officers are covered by
insurance policies maintained by the Company against certain liabilities for
actions taken in their capacities as such, including liabilities under the
Securities Act.

Item 7. Exemption from Registration Claimed.
        -----------------------------------

        Not applicable.

Item 8. Exhibits.
        --------

        Reference is made to the Exhibit Index.

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

        The 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 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.

     (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) That, for the purposes of determining any liability under the Act, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the 1934 Act (and where applicable each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the 1934 Act) that is
incorporated by reference in the 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.

     (4) 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) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 6 or

                                      II-3

<PAGE>

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 Securities 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
Securities Act and will be governed by the final adjudication of such issue.

        Reference is made to the Exhibit Index.

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

        The 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 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.

     (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) That, for the purposes of determining any liability under the Act, each
filing of the registrant's annual report pursuant to Section 13(a) or Section
15(d) of the 1934 Act (and where applicable each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the 1934 Act) that is
incorporated by reference in the 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.

     (4) 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) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 6 or

                                      II-3
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 Securities 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
Securities Act and will be governed by the final adjudication of such issue.

                                      II-4
