                                  Part II

             INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3. Incorporation of Documents by Reference.

The following documents are incorporated by reference herein and shall be
deemed a part hereof:

          (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
     Exchange Act of 1934 (the "Exchange Act").

          (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 common stock, contained in IBM's
     registration statements filed pursuant to Section 12 of the Exchange
     Act, and any amendment or report filed for the purpose of updating any
     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 sold or which deregisters all securities then remaining unsold, shall
be deemed 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 by reference herein shall be deemed to be modified or
superseded for purposes of this Registration Statement to the extent that a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 Any such statement so modified or superseded
shall not be deemed, except as so modified or superseded, to constitute a

Item 5. Interests of Named Experts and Counsel.

          None.

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.

Item 8. Exhibits.

Exhibit Number                   Description

5                   The opinion, dated January 27, 1998, 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.

(b) 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
