to be incorporated by reference herein and to be a part hereof from the date of
filing of such documents.

Any statement contained in a document incorporated or deemed to be incorporated

this Registration Statement to the extent that a statement contained herein or
in any other subsequently filed document which also is or is deemed to be

Item 5.  Interests of Named Experts and Counsel.

          The validity of the IBM common stock, par value $.20 per share,

Item 6.  Indemnification of Directors and Officers.

The By-Laws of IBM (Article VI, Section 6) provide the following:

          "The Corporation shall, to the fullest extent permitted by applicable
law as in effect at any time, indemnify any person made, or threatened to be
made, a party to an action or proceeding whether civil or criminal (including an
action or proceeding by or in the right of the Corporation or any other
corporation of any type or kind, domestic or foreign, or any partnership, joint
venture, trust, employee benefit plan or other enterprise, for which any
director or officer of the Corporation served in any capacity at the request of
the Corporation), by reason of the fact that such person or such person's
testator or intestate was a director or officer of the Corporation, or served
such other corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise in any capacity, against judgments, fines, amounts paid in
settlement and reasonable expenses, including attorneys' fees actually and
necessarily incurred as a result of such action or proceeding, or any appeal
therein. Such indemnification shall be a contract right and shall include the
right to be paid advances of any expenses incurred by such person in connection
with such action, suit or proceeding, consistent with the provisions of
applicable law in effect at any time. Indemnification shall be deemed to be
`permitted' within the meaning of the first sentence hereof if it is not
expressly prohibited by applicable law as in effect at the time."

The Certificate of Incorporation of IBM (Article Eleven) provides the following:

          "Pursuant to Section 402(b) of the Business Corporation Law of the
State of New York, the liability of the Corporation's directors to the
Corporation or its stockholders for damages for breach of duty as a director
shall be eliminated to the fullest extent permitted by the Business Corporation
Law of the State of New York, as it exists on the date hereof or as it may
hereafter be amended. No amendment to or repeal of this Article shall apply to
or have any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal."

<PAGE>


     With certain limitations, Sections 721 through 726 of the New York Business
Corporation Law permit a corporation to indemnify a director or officer made a
party to an action (i) by a corporation or in its right in order to procure a
judgment in its favor unless he shall have breached his duties, or (ii) other
than an action by or in the right of the corporation in order to procure a
judgment in its favor, if such director or officer acted in good faith and in a
manner he reasonably believed to be in or, in certain cases not opposed to such
corporation's interest and additionally, in criminal actions, had no reasonable
cause to believe his conduct was unlawful.

In addition, IBM maintains directors' and officers' liability insurance
policies.

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 this Registration Statement or any material change to such
information in this Registration Statement;

<PAGE>


               (2) that, for the purpose of determining any liability under the
Securities Act of 1933, 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 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 of 1933, each filing of the
registrant'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.

(c) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, 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
of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

The By-Laws of IBM (Article VI, Section 6) provide the following:

          "The Corporation shall, to the fullest extent permitted by applicable
law as in effect at any time, indemnify any person made, or threatened to be
made, a party to an action or proceeding whether civil or criminal (including an
action or proceeding by or in the right of the Corporation or any other
corporation of any type or kind, domestic or foreign, or any partnership, joint
venture, trust, employee benefit plan or other enterprise, for which any
director or officer of the Corporation served in any capacity at the request of
the Corporation), by reason of the fact that such person or such person's
testator or intestate was a director or officer of the Corporation, or served
such other corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise in any capacity, against judgments, fines, amounts paid in
settlement and reasonable expenses, including attorneys' fees actually and
necessarily incurred as a result of such action or proceeding, or any appeal
therein. Such indemnification shall be a contract right and shall include the
right to be paid advances of any expenses incurred by such person in connection
with such action, suit or proceeding, consistent with the provisions of
applicable law in effect at any time. Indemnification shall be deemed to be
`permitted' within the meaning of the first sentence hereof if it is not
expressly prohibited by applicable law as in effect at the time."

The Certificate of Incorporation of IBM (Article Eleven) provides the following:

          "Pursuant to Section 402(b) of the Business Corporation Law of the
State of New York, the liability of the Corporation's directors to the
Corporation or its stockholders for damages for breach of duty as a director
shall be eliminated to the fullest extent permitted by the Business Corporation
Law of the State of New York, as it exists on the date hereof or as it may
hereafter be amended. No amendment to or repeal of this Article shall apply to
or have any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal."
With certain limitations, Sections 721 through 726 of the New York Business
Corporation Law permit a corporation to indemnify a director or officer made a
party to an action (i) by a corporation or in its right in order to procure a
judgment in its favor unless he shall have breached his duties, or (ii) other
than an action by or in the right of the corporation in order to procure a
judgment in its favor, if such director or officer acted in good faith and in a
manner he reasonably believed to be in or, in certain cases not opposed to such
corporation's interest and additionally, in criminal actions, had no reasonable
cause to believe his conduct was unlawful.

In addition, IBM maintains directors' and officers' liability insurance
policies.

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 this Registration Statement or any material change to such
information in this Registration Statement;
(2) that, for the purpose of determining any liability under the
Securities Act of 1933, 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 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 of 1933, each filing of the
registrant'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.

(c) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, 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
of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

requirements for filing on Form S-8 and has duly caused this Registration

authorized, in the town of North Castle, State of New York, on the 8th day of
