                 similar plan--whether in the form of installments or lump
                 sum and whether private or sponsored by a foreign govern-
                 ment--to the extent not provided by direct contributions
                 made by the Participant,

                 (l)  provided that a Participant with such Foreign Service
                      immediately preceded by Continuous Service with the

                      is given, resume employment as a Regular Employee of
                      the Company; and

                 (2)  further provided that a Participant with such Foreign

            B.   Service Credit for Leaves of Absence
                 ____________________________________

                 A Participant who commences a leave of absence granted
                 under IBM's human resources practices then in effect, and
                 who resumes the status of an Executive Level Regular
                 Employee upon completion of the leave, shall be deemed,
                 for all Plan purposes, as having been an actively employed
                 Participant throughout the leave and to have received
                 Compensation during the leave at the rate in effect
                 immediately before the leave began.  If the Participant
                 does not so resume his or her status as an Executive Level
                 Regular Employee for at least 30 days for any reason other
                 than disability or death, the Participant shall be treated
                 as having severed from service with the Company on the
                 date immediately preceding the date the leave began (i.e.,
                 the last day worked), and neither the Participant nor the
                 Participant's Beneficiary shall be eligible for a SERP
                 Benefit.

            C.   Other Service Credit

                 IBM's chief executive officer, or other senior officer
                 designated by the Committee, in his or her sole
                 discretion, may grant Continuous Service credit to an
                 Executive in excess of actual Continuous Service subject
                 to such limitations and conditions as the officer

                ARTICLE 7 - Retirement Date and Commencement of Benefits
                ________________________________________________________


            A.   Normal Retirement Date
                 ______________________

                 A Participant's Normal Retirement Date is the last working
                 day of the month in which his or her 65th birthday occurs;
                 provided that the Participant has completed one year of
                 Continuous Service, and further provided that, if a
                 Participant was born on the first day of the month, the
                 Normal Retirement Date shall be the last day of the month
                 immediately preceding the 65th anniversary of birth.

            B.   Early Retirement Date
                 _____________________

                 A Participant described in any of the following paragraphs
                 may retire from employment on an Early Retirement Date
                 specified in the applicable paragraph below:

                                           -6-



                      1.   A Participant with 30 years or more of
                           Continuous Service may retire on an Early
                           Retirement Date at the end of any month,

                      2.   A Participant with 15 or more years of
                           Continuous Service may retire on an Early
                           Retirement Date at the end of any month at or
                           after reaching age 55,

                      3.   A Participant with five or more years of
                           Continuous Service who is eligible to receive
                           Social Security benefits at age 62 may retire on
                           an Early Retirement Date at the end of any month
                           at or after reaching age 62;

                 provided that in order to retire on an Early Retirement
                 Date a Participant must give the Company at least six
                 months prior written notice, in a form approved by the
                 Plan Administrator, of his or her intention to retire
                 early and to have SERP Benefits commence, unless the Plan
                 Administrator waives such notice requirement.

            C.  Commencement of SERP Benefits
                _____________________________

                 In addition to all other conditions, in no event shall
                 payment of SERP Benefits commence unless and until the
                 Participant applies for such Benefits before his or her
                 Annuity Commencement Date.  In no event shall any SERP
                 Benefit be paid under this Plan unless the Participant (1)
                 meets the Plan's eligibility conditions on the date of his
                 or her retirement, disability, or death, (2) retires (or
                 dies while eligible to retire) under the terms of the IBM
                 Retirement Plan, (3) holds an Executive Level position (as
                 determined by IBM's chief human resources officer in his
                 or her sole discretion) on the date of his or her

                 retirement or death, and (4) complies with the
                 requirements imposed by ARTICLE 11 hereof.


                               ARTICLE 8 - SERP Benefits
                               _________________________


            A.   Normal Retirement Benefit
                 _________________________

                 The Participant's SERP Benefit, when expressed as a single
                 life annuity commencing as of the first day of the month
                 next following the Participant's Normal Retirement Date,
                 shall be equal to one-twelfth of the Phase-In Percentage
                 (defined below) multiplied by the excess of (i) the
                 Pension Credit (defined below) over (ii) the total annual
                 single life annuity benefit at Normal Retirement Age,
                 including the single life annuity benefit attributable to

                                           -7-



                 the Personal Retirement Provision whether such is paid in
                 annuity form or not, payable monthly to the Participant
                 under the IBM Retirement Plan or under any pension
                 arrangement between the Company and a Participant which is
                 payable monthly for life after termination of employment.

                 The Phase-In Percentage shall be determined on the date
                 the Participant retires, and shall not be increased
                 thereafter.  If the Participant retires on January 31,
                 1995, the Phase-In Percentage shall be 27%.  If the
                 Participant retires after January 31, 1995, the Phase-In
                 Percentage shall be 27% plus 2% for each succeeding month
                 (3% for the month of December) up to and including the
                 month of the Participant's retirement, until the Phase-In
                 Percentage reaches 100% for a Participant retiring on or
                 after December 31, 1997.  The Phase-In Percentage shall
                 in no event exceed 100%.

                 The Pension Credit shall be a single life annuity equal to
                 the sum of:

                 (1) 1.7% of Pay up to the Breakpoint, plus 2.55% of Pay in
                 excess of the Break Point (if any), multiplied by the
                 Participant's years of Continuous Service up to a maximum
                 of 20 years,

                 (2) 1.3% of Pay multiplied by the Participant's years of
                 Continuous Service between 20 and 30 years (if any), plus

                 (3) .75% of Pay multiplied by the Participant's Continuous
                 Service between 30 and 35 years (if any).


            B.   Early SERP Benefit
                 __________________

                 If the Participant elects to retire on an Early Retirement
                 Date with an Annuity Commencement Date on or after his or
                 her 60th birthday, the Participant's SERP Benefit when
                 paid in the form of a single life annuity, shall be equal
                 to the SERP Benefit calculated in accordance with Section
                 A of this ARTICLE 8 based on the Participant's years of
                 Continuous Service and Pay on the Participant's Early
                 Retirement Date.

                 If the Participant elects to retire on an Early
                 Retirement Date with an Annuity Commencement Date before
                 his or her 60th birthday, the Participant's SERP Benefit,
                 when paid in the form of a single life annuity, shall be
                 be the amount determined in accordance with the following
                 table:

                                           -8-



                 Participant's       SERP Benefit under
                 Age at Annuity      ARTICLE 8A hereof,
                 Commencement Date   reduced
                 begins              by the following
                 ______              ________________

                 59                     3%
                 58                     7%
                 57                     11%
                 56                     15%
                 55                     20%
                 below 55               20% plus 5% per year for
                                        each year before the Participant's
                                        55th birthday

                 For each month of age falling between the ages or years
                 shown above, one-twelfth of the difference between the
                 respective factors should be added.

                 The reductions described in this Section 8B shall be
                 applied to the Pension Credit calculation under ARTICLE 8A
                 prior to the subtraction of any benefit payable under the
                 IBM Retirement Plan.  The Phase-In Percentage shall be
                 applied to the net SERP Benefit.


            C.   Form and Method of Payment
                 __________________________

                 The normal form of payment of the SERP Benefit for a
                 Participant who is unmarried on his or her Annuity
                 Commencement Date is a single life annuity for the
                 Participant's life.

                 The normal form of payment of the SERP Benefit for a
                 Participant who is married on his or her Annuity
                 Commencement Date is a joint and survivor annuity
                 providing an annuity to the Participant for life, in a
                 monthly amount that is less than that payable under a
                 single life annuity, and a survivor annuity for the life
                 of the Participant's Spouse in a monthly amount equal to
                 50 percent of the monthly amount payable to the married
                 Participant during his or her lifetime.  This form of
                 payment, which constitutes a 50% joint and survivor
                 annuity, shall be the Actuarial Equivalent of the single
                 life annuity otherwise payable to the Participant, based
                 on the age of the Participant and the age of the
                 Participant's Spouse as of the Annuity Commencement Date.

                 A Participant also may elect to be paid under any
                 alternative form of payment available under the IBM
                 Retirement Plan except for the Early Retirement Level
                 Income Option.  Any such election must be made in the
                 manner and form prescribed by IBM's Executive Compensation

                                           -9-



                 Department which may, in certain instances, require the
                 consent of the Participant's Spouse to the alternative
                 form of payment.  Each alternative form of payment shall
                 be the Actuarial Equivalent of the single life annuity
                 payable to the Participant in accordance with this ARTICLE
                 8.

                 Payment of the SERP Benefit shall be made monthly as of
                 the first day of the month beginning with the month
                 following the month in which the Participant retires from
                 employment with the Company.


            D.   Effective Date of Election
                 __________________________

                 Any election under this ARTICLE 8 shall be effective on
                 the later of the Participant's Annuity Commencement Date
                 or 30 days after IBM's Executive Compensation Department
                 receives the election.  The death of a survivor annuitant
                 before the Participant's Annuity Commencement Date
                 automatically revokes any such election.  The death of a
                 survivor annuitant on or after the Participant's Annuity
                 Commencement Date does not revoke the Participant's
                 election.

 
           E.   Revocation of Election
                 ______________________

                 A Participant may revoke an election he or she has made
                 under this ARTICLE 8 at any time before the Participant's
                 Annuity Commencement Date.  In order to be effective, any
                 such revocation must be received by IBM's Executive
                 Compensation Department before the Annuity Commencement
                 Date and must be made in the manner and form prescribed by
                 IBM's Executive Compensation Department.  A timely
                 revocation of an election shall only become effective upon
                 receipt by IBM's Executive Compensation Department.

                 If a Participant revokes an election of an alternative
                 form of payment, the Participant's form of payment shall
                 automatically revert to the normal form of payment
                 prescribed by this ARTICLE 8.  After revoking an election,
                 the Participant may elect an alternative form of payment
                 in accordance with this ARTICLE 8; however, in order to
                 become effective, the Participant's election of an
                 alternative form of payment (other than the normal form of
                 payment) must be received by IBM's Executive Compensation
                 Department before the Participant's Annuity Commencement
                 Date.  A timely election shall become effective as of the
                 later of the Participant's Annuity Commencement Date or 30
                 days after IBM's Executive Compensation Department
                 receives the election.

            F.   SERP Benefits for Disabled Participants
                 _______________________________________

                 A Participant who (i) becomes totally and permanently
                 disabled (as determined in accordance with the terms of
                 the IBM Long Term Disability Plan) after becoming eligible
                 to retire hereunder and while at Executive Level, (ii)
                 remains so disabled until Normal Retirement Age, and (iii)
                 receives benefits under the IBM Long Term Disability Plan,
                 shall be eligible to receive a SERP Benefit upon reaching
                 Normal Retirement Age, notwithstanding his or her
                 ineligibility for that Benefit under other provisions of
                 the Plan.

                 The Annuity Commencement Date for such disabled
                 Participant shall be his or her Normal Retirement Date.
                 The disabled Participant's SERP benefit shall be based on
                 the Participant's Pay and Continuous Service on the date
                 the Participant's IBM Sickness and Accident Income Plan
                 benefits cease.


                      ARTICLE 9 - Preretirement Spousal Annuity
                      _________________________________________

            A preretirement spousal annuity shall be payable to the Spouse
            of a Participant who dies before his or her Annuity
            Commencement Date, but who, on the date of death, is both
            married and eligible to retire immediately hereunder.  The
            preretirement spousal annuity shall be the survivor annuity
            that the Participant's Spouse would have received under the
            Plan had the Participant retired on his or her date of death
            with a 50 percent joint and survivor annuity in effect in
            accordance with the provisions of ARTICLE 8 hereof.  In no
            event shall the preretirement spousal annuity be payable to
            anyone other than the Participant's Spouse on the date of the
            Participant's death.

                     ARTICLE 10 - Suspension of Benefits for Reemployed
                     __________________________________________________

                                  Retired Participants
                                  ____________________

            If a retired Participant is reemployed by the Company, any SERP
            Benefits otherwise payable to the Participant shall be
            suspended during the period of reemployment.  If the reemployed
            Participant subsequently completes one year of Continuous
            Service and retires from the Company, the Participant shall be
            eligible for SERP Benefits under the terms of the Plan in
            effect on the date the Participant's employment with the
            Company ceases, based on the Participant's Pay and Continuous
            Service as of that date, but reduced by the Actuarial
            Equivalent of any Benefits paid before the Participant's
            reemployment.  If the reemployed Participant again retires

                                           -11-



            without having completed one year of Continuous Service during
            his or her period of reemployment, the SERP Benefits being paid
            to the Participant immediately before his or her reemployment
            shall resume, without adjustment, immediately following his or
            her retirement.


                           ARTICLE 11 - Forfeiture
                           _______________________


            A.   Competitive or Prejudicial Conduct
                 __________________________________

                 A Participant shall not render services for any
                 organization or engage directly or indirectly in any
                 business which, in the judgment of the chief executive
                 officer of the Company or other senior officer designated
                 by the Committee, is or becomes competitive with the
                 Company, or which organization or business, or the
                 rendering of services to such organization or business, is
                 or becomes otherwise prejudicial to or in conflict with
                 the interests of the Company.  For a Participant whose
                 employment has terminated, the judgment of the chief
                 executive officer shall be based on the Participant's
                 position and responsibilities while employed by the
                 Company, the Participant's post-employment
                 responsibilities and position with the other organization
                 or business, the extent of past, current and potential
                 completion or conflict between the Company and the other
                 organization or business, the effect on the Company's
                 customers, suppliers and competitors of the Participant
                 assuming the post-employment position, the guidelines
                 established in the then current edition of IBM's booklet,
                 Business Conduct Guidelines, and such other considerations
                 ___________________________

                 as are deemed relevant given the applicable facts and
                 circumstances.  A Participant who has retired shall be
                 free, however, to purchase as an investment or otherwise,
                 stock or other securities of such organization or business
                 so long as they are listed upon a recognized securities
                 exchange or traded over-the-counter, and such investment
                 does not represent a substantial investment to the
                 Participant or a greater than 10 percent equity interest
                 in the organization or business.


            B.   Disclosure of Confidential Information
                 ______________________________________

                 A Participant shall not, without prior written
                 authorization from the Company, disclose to anyone outside
                 the Company, or use in other than the Company's business,
                 any confidential information or material, as defined in
                 the Company's Agreement Regarding Confidential Information
                 and Intellectual Property, related to the business of the
                 Company, acquired by the Participant either during or

                                           -12-



                 after employment with the Company.


            C.   Disclosure and Assignment of Rights
                 ___________________________________

                 A Participant, pursuant to the Company's Agreement
                 Regarding Confidential Information and Intellectual
                 Property shall disclose promptly and assign to the Company
                 all right, title, and interest in any invention or idea,
                 patentable or not, made or conceived by the Participant
                 during employment by the Company, relating in any manner
                 to the actual or anticipated business, research, or 
                 development work of the Company and shall do anything 
                 reasonably necessary to enable the Company to secure a 
                 patent where appropriate in the United States and in other 
                 countries.


            D.   Forfeiture and Rescission
                 _________________________

                 Upon retirement, and from time to time thereafter upon
                 request by the Committee, the Participant shall certify on
                 a form acceptable to the Committee that he or she is in
                 compliance with the terms and conditions of the Plan.
                 Failure to comply with the provisions of Section A, B, or
                 C of this ARTICLE prior to retirement or receipt of any
                 Benefit payment hereunder shall cause the forfeiture of
                 all SERP Benefits even if the failure to comply is not
                 discovered until Benefits have commenced.  Failure to
                 comply with the provisions of Section A, B, and C of this
                 ARTICLE after SERP Benefits have commenced hereunder shall
                 cause any such payments to be rescinded from the point in
                 time when the conduct which led to the failure to comply
                 occurred.  The Plan Administrator shall notify the
                 Participant in writing of any such rescission, and within
                 ten days after receiving a notice of rescission from the
                 Company, the Participant shall pay to the Company in cash
                 the amount of any payment that has been rescinded in
                 accordance with this ARTICLE.


                 ARTICLE 12 - Information for Benefits Calculations
                 __________________________________________________


            A.   Incomplete or Incorrect Information
                 ___________________________________

                 Any delay in receiving from a Participant or Beneficiary
                 information requested by the Company's Executive
                 Compensation Department, including but not limited to
                 information regarding a Participant's Spouse or other
                 factors necessary for the calculation of Benefits under
                 the Plan, shall result in the Benefits payable being based
                 initially on the information then available to IBM's

                                           -13-



                 Executive Compensation Department and the Plan
                 Administrator, and their estimate of any unavailable
                 information.  If additional or different information
                 thereafter becomes available to IBM's Executive
                 Compensation Department or the Plan Administrator,
                 Benefits shall be adjusted appropriately as determined by
                 the Plan Administrator.


            B.   Overpayments
                 ____________

                 If any overpayment of Benefits is made under the Plan, the
                 amount of the overpayment may be set off against further
                 amounts payable to or on account of the person who
                 received the overpayment until the overpayment has been
                 recovered in full.  The foregoing remedy is not intended
                 to be exclusive.


                           ARTICLE 13 - Alienation of Benefits
                           ___________________________________

            No Benefit payable under the Plan shall be subject to
            alienation, sale, transfer, assignment, pledge, attachment,
            garnishment, lien, levy or like encumbrance.  No Benefit under
            the Plan shall in any manner be liable for or subject to the
            debts or liabilities of any person entitled to Benefits under
            the Plan.


                            ARTICLE 14 - Withholding Taxes
                            ______________________________

            The Company and the Plan Administrator shall withhold such
            taxes and make such reports to governmental authorities as they
            reasonably believe to be required by law.



                  ARTICLE 15 - Distributions to Minors and Incompetents
                  _____________________________________________________

            If the Plan Administrator determines that any Participant or
            Beneficiary receiving or entitled to receive Benefits under the
            Plan is incompetent to care for his or her affairs, and in the
            absence of the appointment of a legal guardian of the property
            of the incompetent, payments due under the Plan (unless prior
            claim thereto has been made by a duly qualified guardian,
            committee or other legal representative) may be made to the
            spouse, parent, brother or sister or other person, including a
            hospital or other institution, deemed by the Plan Administrator
            to have incurred or to be liable for expenses on behalf of such
            incompetent.

            In the absence of the appointment of a legal guardian of the
            property of a minor, any minor's share of Benefits under the

                                           -14-



            Plan may be paid to such adult or adults as in the opinion of
            the Plan Administrator have assumed the custody and principal
            support of such minor.

            The Plan Administrator, however, in its sole discretion, may
            require that a legal guardian for the property of any such
            incompetent or minor be appointed before authorizing the
            payment of Benefits in such situations.  Benefit payments made
            under the Plan in accordance with determinations of the Plan
            Administrator pursuant to this ARTICLE 15 shall be a complete
            discharge of any obligation arising under the Plan with respect
            to such Benefit payments.

 
                     ARTICLE 16 - No Right to Employment
                      ___________________________________

            Nothing herein contained shall be deemed to give any employee
            the right to be retained in the service of the Company or to
            interfere with the right of the Company to discharge any
            employee at any time without regard to the effect that such
            discharge may have upon the employee under the Plan.


                          ARTICLE 17 - Unfunded Plan
                          __________________________

            The Plan shall be unfunded.  The Company shall not be required
            to segregate any assets to provide Benefits, nor shall the Plan
            be construed as providing for such segregation, nor shall the
            Company or the Committee be deemed to be a trustee of any
            assets of the Plan.  Any liability of the Company to any
            Participant or Beneficiary with respect to SERP Benefits shall
            be based solely upon any contractual obligations created by the
            Plan.  No such obligation of the Company shall be deemed to be
            secured by any pledge or other encumbrance or any property of
            the Company.  Neither the Company nor the Committee shall be
            required to give any security or bond for the performance of
            any obligation created by the Plan.

                 used in the female gender, and vice versa, and wherever
                 any words are used herein in the singular form, they shall

                 form, and vice versa.

            B.   Severability

                 If any provision of the Plan is held illegal or invalid
                 for any reason, such illegality or invalidity shall not
                 affect the remaining parts of the Plan, and the Plan shall
                 be construed and enforced as if such illegal or invalid
                 provision had never been inserted herein.

                 ______________________

                 The Company shall from time to time issue to Participants
