The following documents are incorporated by reference herein and shall be deemed

                  (a) The Annual Report of International Business Machines
         Corporation ("IBM") on Form 10-K for the fiscal year ended December 31,
         1996, filed pursuant to Section 13(a) or 15(d) of the Securities

                  (b) All other reports filed by IBM pursuant to Section 13(a)
         or 15(d) of the Exchange Act since December 31, 1996.

                  (c) The description of IBM's Capital Stock, par value $.50 per
         share, contained in IBM's Registration Statement No. 333-21073, as
         filed with the Securities and Exchange Commission on February 4, 1997,
         including any amendments or reports filed for purposes of updating such
         description.

All documents filed by IBM pursuant to Sections 13(a), 13(c), 14 and 15(d) of
the Exchange Act, after the date hereof and prior to the filing of a
post-effective amendment which indicates that all securities offered have been

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
incorporated by reference herein modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified
or superseded, to constitute a part of this Registration Statement.

Item 5. Interests of Named Experts and Counsel.

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 any 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.

5                               The opinion, dated July 14, 1997, of David S.
                                Hershberg, Vice President and Assistant General
                                Counsel of IBM



23.1                            Consent of Independent Accountants

23.2                            Consent of Counsel (included in Exhibit 5)

24                              Powers of attorney

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, 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 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.

(h) 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 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 Act and will be governed by the final adjudication of
such issue.



                                   SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the town of North Castle, State of New York, on the 14th day of
July 1997.
