provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

officers, directors and third parties acting on behalf of Commerce One if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of Commerce One, and, in any criminal action or
proceeding, the indemnified party had no reason to believe his or her conduct
was unlawful.

         Commerce One has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
Commerce One's Bylaws, and intends to enter into indemnification agreements with
any new directors and executive officers in the future.

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

                                      II-3
<PAGE>

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 Commerce
One's annual report pursuant to Section 13(a) or Section 15(d) of the 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 Commerce One pursuant to the foregoing provisions, or otherwise, Commerce One
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 Commerce One of expenses
incurred or paid by a director, officer or controlling person of Commerce One 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, Commerce One 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.

         The validity of the common stock in this offering will be passed upon
for Commerce One by Wilson Sonsini Goodrich & Rosati, Professional Corporation,
Palo Alto, California. As of October 15, 2000, investment partnerships composed

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law permits a
corporation to include in its charter documents, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

                                      II-2
Article IX of Commerce One's Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

         Article VI of Commerce One's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of Commerce One if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of Commerce One, and, in any criminal action or
proceeding, the indemnified party had no reason to believe his or her conduct
was unlawful.

         Commerce One has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
Commerce One's Bylaws, and intends to enter into indemnification agreements with
any new directors and executive officers in the future.

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

                                      II-3
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 Commerce
One's annual report pursuant to Section 13(a) or Section 15(d) of the 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 Commerce One pursuant to the foregoing provisions, or otherwise, Commerce One
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 Commerce One of expenses
incurred or paid by a director, officer or controlling person of Commerce One 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, Commerce One 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
