ITEM 9. UNDERTAKINGS

        A. 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 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 of 1933, as amended (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.

        B. The undersigned registrant hereby undertakes that, for 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 Securities Exchange Act of 1934 (and, where
           applicable, each filing of an employee benefit plan's annual
           report pursuant to Section 15(d) of the Securities Exchange Act of
           1934) 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.

       C.  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 Delaware

                                       -2-

<PAGE>

General Corporation Law, the Certificate of Incorporation of the registrant,
the Bylaws of the registrant, indemnification agreements entered into between
the registrant and its officers and directors or 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 in successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered hereunder, 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 of 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 9. UNDERTAKINGS

        A. 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 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 of 1933, as amended (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.

        B. The undersigned registrant hereby undertakes that, for 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 Securities Exchange Act of 1934 (and, where
           applicable, each filing of an employee benefit plan's annual
           report pursuant to Section 15(d) of the Securities Exchange Act of
           1934) 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.

       C.  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 Delaware

                                       -2-
General Corporation Law, the Certificate of Incorporation of the registrant,
the Bylaws of the registrant, indemnification agreements entered into between
the registrant and its officers and directors or 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 in successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered hereunder, 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 of 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.

                                       -3-
