         1.1 Introduction. This "Supplemental Plan," amended and restated

retired or otherwise terminated Employment prior to January 1, 1989 shall be
subject to the terms of the Supplemental Plan as in effect at the date of
retirement or termination, except to the extent otherwise provided herein. This
Supplemental Plan is intended to be a non-qualified supplemental retirement plan
which is unfunded and maintained primarily for the purpose of providing deferred
compensation for a select group of management or highly compensated employees of
the Company, pursuant to sections 201, 301 and 401 of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA") and, as such, to be exempt
from the provisions of Parts 2, 3 and 4 of Subtitle B of Title I of ERISA.

in Rule 13d-3 under the Act) directly or indirectly of 30% or more of the
outstanding stock of Union Pacific (calculated as provided in Rule 13d-3(d)

merger as immediately before or (II) any sale, lease, exchange or other transfer
(in one transaction or a series of related transactions) of all or substantially

with any new directors whose election, or nomination for election by Union

included in the Supplemental Plan by virtue of action by the Administrator,
unless the Board of Directors of Union Pacific ratifies such action not later
than its first regularly scheduled meeting held subsequent to the taking of such

units) awarded a Participant by the Compensation and Benefits Committee of the
Company's Board of Directors (or any successor thereto) in lieu of a cash award
under the Executive Incentive Plan,

compensation limit under section 401(a)(17) of the Code or the provisions of
Alternative II-D set forth in Section 3.01(c) of the Pension Plan. Awards of

                          AMOUNT AND PAYMENT OF PENSION

         2.1 Normal Supplemental Pension. Subject to the provisions of Articles
Three, Five and Eleven, a Participant retiring on a Normal Retirement Date under
the Pension Plan (including a Participant who has become a Disabled Participant
under the Pension Plan and who ceases to be such on the Normal Retirement Date)
shall be entitled to receive a Normal Supplemental Pension, in the form of a
single life annuity commencing on the Participant's Normal Retirement Date,
equal to the excess, if any, of:

                  (a) the annual Accrued Benefit payable at Normal Retirement
Date computed on the basis of the formula provided in Section 5.01 of the
Pension Plan, determined without regard to the limitation described in Section
5.02 of the Pension Plan, and including under such formula any amounts of Final
Average Compensation that were excluded from consideration for the Participant
under the Pension Plan and all Incentive Compensation payable to the Participant
within the 120-calendar-month period immediately preceding the date on which the
Participant ceases to be a Covered Employee, and utilizing Total Credited
Service up to 40 years in place of Credited Service under Article IV of the
Pension Plan and Total Offset Service up to 40 years in place of "offset
service" under Article V of the Pension Plan, over

                  (b) the annual nonforfeitable Accrued Benefit payable at
Normal Retirement Date actually determined to be due under the Pension Plan.

For purposes of determining benefits under the Supplemental Plan, any actuarial
adjustments for a delay in the commencement of payment beyond the Normal
Retirement Date or otherwise that apply under the Pension Plan in calculating
the benefit described in (b), above, shall also apply to calculate the benefit
described in (a), above.

         2.2 Early Supplemental Pension.

                  (a) Participant Retires on Early Retirement Date. The
following provisions apply to a Participant retiring on an Early Retirement Date
under the Pension Plan:

                           (i) Benefit Payable on Normal Retirement Date.
Subject to the provisions of Articles Three, Five and Eleven, a Participant
retiring on an Early Retirement Date under the Pension Plan shall be entitled to
receive a Normal Supplemental Pension in the form of a single life annuity
commencing at Normal Retirement Date, computed in accordance with Section 2.1
based on Total Credited Service, Total Offset Service, etc. as of the
Participant's Early Retirement Date. A Participant retiring on an Early
Retirement Date shall include a Participant who has become a Disabled
Participant under the Pension Plan and who ceases to be a Disabled Participant
on an Early Retirement Date.

                           (ii) Benefit Payable on Early Retirement Date. In
lieu of the benefit described in (i), above, subject to the provisions of
Articles Three, Five and Eleven, such Participant may receive an Early
Supplemental Pension, in the form of a single life annuity commencing at the
date prior to his Normal Retirement Date on which he elects to start his


                                       6



pension under the Pension Plan. The Early Supplemental Pension shall be computed
in the same manner as the Normal Supplemental Pension, but with the amounts
described in Sections 2.1(a) and (b) adjusted for payment as of the early
benefit start date in accordance with Section 6.03 of the Pension Plan, taking
into account any additional years of age described in Section 1.2(d)(ii) for
purposes of adjusting both the gross and offset portions of the benefit in
Section 2.1(a) (except as provided otherwise in Section 2.12 or 2.13).

                  (b) Participant Retires on Early Supplemental Pension
Retirement Date. The following provisions apply to a Participant retiring on an
Early Supplemental Pension Retirement Date:

                           (i) Participant Is Eligible to Start Pension Plan
Benefit. Subject to the provisions of Articles Three, Five and Eleven, a
Participant retiring on an Early Supplemental Pension Retirement Date who is
eligible to start a benefit under the Pension Plan upon his retirement may
receive a Normal or Early Supplemental Pension as described in subsection (a);
provided, however, that, for purposes of determining the Early Supplemental
Pension as described in (a)(ii), above:

                                    (A) the amount described in Section 2.1(a)
shall be adjusted for payment as of the early benefit start date in accordance
with Section 6.03 of the Pension Plan, taking into account any additional years
of age described in Section 1.2(d)(ii) for purposes of adjusting both the gross
and offset portions of the benefit in Section 2.1(a) (except as provided
otherwise in Section 2.12 or 2.13); and

                                    (B) the amount described in Section 2.1(b)
shall be adjusted for payment as of the early benefit start date in accordance
with Section 6.04 of the Pension Plan.

                           (ii) Participant Is Not Eligible to Start Pension
Plan Benefit. Subject to the provisions of Article Three, Five and Eleven, a
Participant retiring on an Early Supplemental Pension Retirement Date who either
is not vested in or is not eligible to start a benefit under the Pension Plan
upon his retirement shall receive an Early Supplemental Pension, in the form of
a single life annuity commencing on the first day of the month following his
Early Supplemental Pension Retirement Date, the amount of which shall be
determined as follows:

                                    (A) Prior to the earliest date, if any, that
the Participant is eligible to start benefits under the Pension Plan, the Early
Supplemental Pension payable under this provision shall be computed in the same
manner as the Normal Supplemental Pension, except that:

                                             (I) the amount described in Section
2.1(a) shall be adjusted for payment as of the early benefit start date as
described in Section 6.03 of the Pension Plan for Pension Plan payments starting
on an Early Retirement Date, taking into account any additional years of age
described in Section 1.2(d)(ii) for purposes of adjusting both the gross and
offset portions of the benefit in Section 2.1(a) (except as provided otherwise
in Section 2.12 or 2.13); and


                                       7



                                             (II) the amount described in
Section 2.1(b) shall be zero for purposes of determining the Early Supplemental
Pension payable prior to the earliest date, if any, on which the Participant is
eligible to start benefits under the Pension Plan.

                                    (B) On and after the earliest date, if any,
that the Participant is eligible to start benefits under the Pension Plan, the
Early Supplemental Pension shall equal the excess of:

                                             (I) the amount described in Section
2.2(b)(ii)(A)(I), above, calculated as of the early benefit start date on which
payments under the Supplemental Plan began, over

                                             (II) the amount described in
Section 2.1(b) reduced for early payment in accordance with Section 6.04 of the
Pension Plan as of such "earliest date" whether or not the Participant's Pension
Plan benefit starts on that date.

Effective for benefits starting before July 25, 2002, payments under this
subparagraph (b)(ii) were made as described above unless the Administrator
advised the Participant to the contrary.

         2.3 Postponed Supplemental Pension. Subject to the provisions of
Articles Three, Five and Eleven, a Participant who retires on a Postponed
Retirement Date shall be entitled to a Postponed Supplemental Pension, in the
form of a single life annuity commencing at the Postponed Retirement Date, which
is equal to the Normal Supplemental Pension, computed in accordance with Section
2.1 based on his Total Credited Service, Total Offset Service, etc. as of the
Participant's Postponed Retirement Date (instead of his Normal Retirement Date)
or, if earlier, as of his Required Beginning Date. If a Participant's benefits
begin on his Required Beginning Date and prior to his termination of Employment,
the Participant's benefits shall be adjusted thereafter as described in Section
8.06 of the Pension Plan.

         2.4 Surviving Spouse's Pension (Post-Retirement Automatic Survivor
Annuity).

                  (a) The Surviving Spouse of a Participant who dies while
receiving a Normal or Postponed Supplemental Pension or an Early Supplemental
Pension determined under Section 2.2(a), relating to retirement on a date that
qualifies as an Early Retirement Date under the terms of the Pension Plan, shall
be entitled to a Surviving Spouse's Pension equal to one-half of the single life
annuity amount of the Normal, Early, or Postponed Supplemental Pension payable
to such deceased Participant under the Supplemental Plan. Such Surviving
Spouse's Pension shall be payable to such Spouse in equal monthly payments for
life, commencing on the first day of the month immediately following the death
of such Participant.

                  (b) The Surviving Spouse of a Participant who dies while
receiving an Early Supplemental Pension determined under Section 2.2(b),
relating to retirement on an Early Supplemental Pension Retirement Date (i.e., a
date that does not qualify as an Early Retirement Date under the terms of the
Pension Plan), shall be entitled to a Surviving Spouse's Pension. The Surviving
Spouse's Pension shall be payable in equal monthly payments for the Surviving
Spouse's life, commencing on the first day of the month immediately following
the Participant's death, which shall equal one-half of the single life annuity
amount calculated for the Participant


                                       8



under Section 2.2(b)(i)(A) or 2.2(b)(ii)(A)(I), as appropriate, as of the
Participant's early benefit start date; provided, however, that monthly payments
to the Surviving Spouse shall be reduced by any pre-retirement survivor benefit
that the Surviving Spouse is entitled to receive from the Pension Plan from the
earliest date following the Participant's death that such survivor benefit is
payable from the Pension Plan, even if benefits to the Surviving Spouse have not
started on that earliest date. Effective for benefits starting before July 25,
2002, payments under this subsection (b) were made as described above unless the
Administrator advised the Participant and/or Surviving Spouse to the contrary.

                  (c) The Surviving Spouse's Pension described in this Section
2.4 is payable in addition to any other death benefit that may be payable to the
Surviving Spouse or other beneficiary of the Participant under the form of
payment in which the Participant's Supplemental Pension is paid pursuant to
Article Three. However, except with respect to Participants who qualify for the
enhancements described in Sections 2.8, 2.10, 2.11, 2.12 or 2.13, in no event
shall the Surviving Spouse who is entitled to the Surviving Spouse's Pension, if
also designated as the Participant's beneficiary under a joint and survivor
annuity payable under the Supplemental Plan, receive a total benefit from the
Supplemental Plan that is more than 100% of the retirement income otherwise
payable to the Participant under the Supplemental Plan.

         2.5 Involuntary Termination Supplemental Pension.

                  (a) The following provisions apply with respect to Change in
Control occurring on or before November 15, 2000:

                           (i) In lieu of the benefit described in Section 2.1
or 2.2, if the Employment of any Participant (A) who is an elected officer, and
(B) whose highest annual Compensation (including Incentive Compensation) is not
less than $200,000, is involuntarily terminated prior to the 5th anniversary of
a Change in Control and prior to Normal Retirement Date, and if, at the time of
such involuntary termination, such Participant has completed 10 or more years of
Vesting Service and is within the 10-year period immediately preceding Normal
Retirement Date, such Participant shall be entitled to an Involuntary
Termination Supplemental Pension commencing at Normal Retirement Date, equal to
the Normal Supplemental Pension computed in accordance with Section 2.1 as of
his termination date, with the amount in Section 2.1(a) based on Total Credited
Service and Total Offset Service credited and as projected to be credited to the
5th anniversary of such Change in Control (or, if earlier, the Participant's
Normal Retirement Date). In lieu thereof, such Participant may elect an Early
Retirement Date and receive an Involuntary Termination Supplemental Pension
commencing on such Early Retirement Date equal to the Early Supplemental Pension
computed in accordance with Section 2.2 as of the Early Retirement Date, with
the amount in Section 2.1(a) based on Total Credited Service and Total Offset
Service credited and as projected to be credited to the 5th anniversary of such
Change in Control (or, if earlier, the Participant's Normal Retirement Date)
adjusted in accordance with Section 6.03 of the Pension Plan, but based on the
Participant's projected age on the 5th anniversary date of such Change in
Control (or, if earlier, Normal Retirement Date).

                           (ii) In lieu of the benefit described in Section 4.2,
if the Employment of any Participant (other than a Participant described in (i)
above), is involuntarily terminated prior to the 5th anniversary of a Change in
Control and prior to Normal Retirement Date, and if


                                       9



such Participant would have attained age 55 and been credited with at least 15
years of Vesting Service had the Participant continued to be employed to such
5th anniversary, such Participant shall be entitled to an Involuntary
Termination Supplemental Pension commencing on the date provided for a benefit
described under Section 4.2, equal to the benefit amount computed under Section
4.2, with the amount in Section 2.1(a) based on Total Credited Service and Total
Offset Service credited and as projected to be credited to the 5th anniversary
of such Change in Control (or, if earlier, the Participant's Normal Retirement
Date) provided that, in the event such Participant elects to receive the
supplemental pension commencing on a date prior to his Normal Retirement Date,
the Actuarial Equivalent referred to in Section 4.2 shall be based on the
Participant's projected age on the 5th anniversary date of such Change in
Control (or, if earlier, his Normal Retirement Date).

                           (iii) For purposes of this subsection (a), the term
"involuntary termination" means any action taken subsequent to a Change in
Control by Union Pacific or the Company or any successor to, or assignee of, its
obligations under this Supplemental Plan, either (A) terminating Employment for
other than an unlawful act or, (B) without the consent of a Participant,
adversely affecting employment status by reducing earnings or demoting in title,
or lessening of authority or responsibilities, or changing the situs of
employment which requires a change of residence, of such Participant and, as a
result, such Participant terminates Employment.

                           (iv) In the event any amount paid or benefit
otherwise received by a Participant under the Supplemental Plan shall be
determined by the Internal Revenue Service to constitute an "excess parachute
payment" as such term is defined in section 280G of the Code, together with all
other payments and benefits outside of the Supplemental Plan that are taken into
account in making such determination, and to be subject to an excise tax under
section 4999 of the Code, or any successor provision thereto (collectively,
"Excise Tax"), the Company shall pay to the Participant an additional amount
such that after taking into account all income and employment taxes, including
the Excise Tax, interest and penalties with respect thereto, incurred by the
Participant on the receipt of such additional amount, the Participant is left
with the same after-tax amount the Participant would have been left with had no
Excise Tax been imposed.

                  (b) A Participant who is affected by a Change in Control
occurring on or after November 16, 2000 shall have his eligibility for and
amount of Supplemental Plan benefits determined pursuant to the terms of the
Union Pacific Corporation Key Employee Continuity Plan adopted November 16,
2000, as may be amended from time to time.

         2.6 Suspension of Benefits.

                  (a) Date of Benefit Suspension. Notwithstanding any provisions
of Article Two or Article Four to the contrary, the payment of the pension to
which a Participant is otherwise entitled under the Supplemental Plan shall be
suspended during any period for which payment of a pension to which such
Participant may otherwise be entitled under the Pension Plan is (or would be)
suspended under the terms of the Pension Plan due to such Participant's return
to Employment. The pension payable to the Participant under the Supplemental
Plan which has been suspended shall resume on the same date as payments to the
Participant under the Pension Plan resume (or would resume if the Participant
had been entitled to such a pension).


                                       10



                  (b) Resumption of Payments. Upon the resumption of payment of
such pension hereunder to such Participant, the resumed benefits shall be
recalculated taking into account any increases in the Participant's Total
Credited Service, Total Offset Service, Incentive Compensation, age and so
forth. However, no actuarial or other adjustment shall be made to reflect such
suspension. The resumed benefit shall be offset, in a manner prescribed by the
Administrator, by (i) any benefit paid during a month in which benefits should
have been suspended but were not, which has not previously been repaid to the
Company by the Participant, and (ii) the Actuarial Equivalent of any benefits
paid prior to Normal Retirement Date.

                  (c) Form of Resumed Payments. The resumed payments (including
any additional benefits earned during the period of suspension) under the
Supplemental Plan shall be paid to the Participant in the same form of payment
as the Participant elects for his resumed payments under the Pension Plan. If
the Participant is not entitled to any benefits under the Pension Plan, the
resumed payments under the Supplemental Plan shall resume in the same form of
payment in effect for the Participant before payments were suspended.

         2.7 Benefits for Special 1990-1992 Window Participants. Each Special
1990-1992 Window Participant (or the Surviving Spouse or other beneficiary of a
Special 1990-1992 Window Participant) shall receive from the Supplemental Plan
in each month the individual receives a payment from the Pension Plan prior to
November 1, 1994, an amount equal to the excess of:

                  (a) the amount that would have been payable to the individual
from the Pension Plan for that month, had the provisions of Section 6.12 (prior
to 1999, Section 6.11) of the Pension Plan not applied; over

                  (b) the amount actually paid to the individual from the
Pension Plan for that month.

         2.8 Window Benefits for Highly Compensated Employees. Each Participant
who was a Covered Employee under the Pension Plan, who retired under an early
retirement window program described in Section 6.06, 6.07 or 6.09 of the Pension
Plan but on the relevant date was excluded from participation in the Pension
Plan pursuant to Section 3.01(c) of the Pension Plan or was excluded from
participation in the window program due to his status as an officer, shall be
deemed for all purposes under the Supplemental Plan to have the additional years
of service and the additional years of age that would have been credited to the
Participant under the Pension Plan pursuant to such program if Section 3.01(c)
of the Pension Plan had not applied to the Participant; provided, however, that
service credited pursuant to this Section shall not cause the Participant's
Total Credited Service or Total Offset Service to exceed 40 years, and no
Participant's deemed age shall exceed 65 years.

         2.9 1991 Cost-of-Living Increase. Effective December 1, 1991, the
monthly benefit payment to any person who is (a) a former employee of the
Company then receiving retirement benefits under this Supplemental Plan
(regardless of the employee's termination date), or (b) a beneficiary or
surviving spouse then receiving death benefits under this Supplemental Plan
shall be increased by the percentage shown in the following table.

However, such increase shall only be applied to the portion, if any, of the
amount being received due to participation in this Supplemental Plan that does
not exceed the difference between $108,963 per year and the amount being
received by such person under the Pension Plan as increased by resolutions of
the Board of Directors of Union Pacific unanimously adopted on June 27, 1974 and
May 31, 1979 (before adjustment to reflect the increases effective December 1,

comparable requirements set forth in the Pension Plan for Covered Employees
whose 1998 Compensation, as defined in Section 2.18(c) of the Pension Plan, is
less than $110,000 exceeds a Departmental Limit, such Covered Employees shall be

                                MANNER OF PAYMENT

         3.1 Payments For Retirements Under Section 2.1, 2.2(a), 2.2(b)(i) and
2.3. Except as provided in Section 3.3, if (a) a Participant retires on a Normal
Retirement Date, an Early Retirement Date, an Early Supplemental Pension
Retirement Date, or a Postponed Retirement Date under Section 2.1, 2.2(a),
2.2(b)(i) or 2.3, and (b) at retirement is eligible to start both a Supplemental
Pension under Article Two of this Supplemental Plan and a pension under the
Pension Plan, payment of the Supplemental Pension shall begin on the date the
Participant's Pension Plan benefits begin pursuant to his election under the
Pension Plan (and not earlier or later). In addition, the Supplemental Pension
shall be paid in the same form, and shall be subject to the same adjustment for
form of payment and the same Beneficiary designation, as apply to the
Participant's Pension Plan benefit; provided, however, that in the event the
Participant is eligible for and elects a level income option under the Pension
Plan, the Supplemental Pension shall be paid as a single life annuity.

         3.2 Payments For Retirements Under Section 2.2(b)(ii). Except as
provided in Section 3.3, if a Participant retires on an Early Supplemental
Pension Retirement Date, and at retirement either is not vested in or is not
eligible to start a pension under the Pension Plan, payment of his Supplemental
Pension shall begin on the first day of the month next following the
Participant's Early Supplemental Pension Retirement Date. The Participant's
Supplemental Pension will be paid in the form of a single life annuity. The
Participant is not eligible to elect payment of his Supplemental Pension in any
other form.

         3.3 Payments Starting Before July 25, 2002. Effective for benefits
starting before July 25, 2002, the Administrator may have permitted a
Participant described in Section 3.1 or 3.2 who was retiring on an Early
Supplemental Pension Retirement Date that did not qualify as an Early Retirement
Date under the Pension Plan to elect, in the manner prescribed by the
Administrator, to receive payment of his Supplemental Pension in any form of
payment described in Article VIII of the Pension Plan that would have been
available to the Participant had he retired on an Early Retirement Date under
the Pension Plan. If the Participant was permitted to and elected a form of
payment other than a single life annuity, the Supplemental Pension payments are
actuarially adjusted for the form of payment elected by the Participant, as
determined by the Administrator, using factors for that purpose set forth in the
Pension Plan.

                                  ARTICLE FOUR

                                     VESTING

         4.1 Termination Prior to Vesting.

                  (a) A Participant whose Employment terminates before April 27,
1989, before Early or Normal Retirement Date, and before the completion of 10
years of Vesting Service (including within such Vesting Service not less than 5
years of actual Vesting Service under the Pension Plan) shall not be entitled to
any benefit under this Supplemental Plan.

                  (b) Except as provided in Section 2.5 or 2.12(b)(ii), a
Participant who terminates Employment on or after April 27, 1989, before Early
or Normal Retirement Date, and before completion of 5 years of actual Vesting
Service under the Pension Plan (treating as actual service for this purpose,
service described in Section 1.2(p)(ii) or credited under Section 2.5) shall not
be entitled to any benefit under this Supplemental Plan; provided, however, that
the Chief Executive Officer of Union Pacific may reduce the required years of
actual Vesting Service to 3 if the Chief Executive Officer of Union Pacific
determines that such change would not be disadvantageous to the Company in the
case of any Participant. The Chief Executive Officer of Union Pacific shall make
such determination by the date the Participant terminates Employment.

         4.2 Termination After Vesting. Except as provided in Section 2.5,
2.12(b)(ii) or 4.4 or Articles Five and Eleven, a Participant who:

                  (a) terminates Employment before Normal or Early Retirement
Date and before Early Supplemental Pension Retirement Date but after (i)
completing 5 (or 3, if applicable) years of actual Vesting Service under the
Pension Plan (treating as actual service for this purpose, service described in
Section 1.2(p)(ii) or credited under Section 2.5) in the case of Employment
termination on or after April 27, 1989, or (ii) completing 10 years of Vesting
Service (including at least 5 years of actual Vesting Service under the Pension
Plan) in the case of Employment termination prior to April 27, 1989; or

                  (b) becomes a Disabled Participant under the Pension Plan and
ceases to be a Disabled Participant prior to Normal or Early Retirement Date,

shall be entitled to receive, commencing on the Participant's Normal Retirement
Date, the Normal Supplemental Pension computed under Section 2.1 as of the date
the Participant terminated Employment or ceased to be a Disabled Participant. In
lieu thereof, such Participant shall receive a Supplemental Pension commencing
on the earliest of:

                           (i) any date prior to the Participant's Normal
Retirement Date on which the Participant starts his benefit payments from the
Pension Plan;

                           (ii) in the case of a Participant who is credited
with additional years of age described in Section 1.2(d)(ii) and, as a result,
would be deemed to reach age 55 and become eligible to start his Supplemental
Plan benefits earlier than his Pension Plan benefits, the first day


                                       26



of the month following the later of (A) the Participant's termination of
Employment, or (B) the Participant's 55th birthday (determined taking into
account additional years of age described in Section 1.2(d)(ii)); or

                           (iii) in the case of a Participant who is not vested
under the Pension Plan, the first day of the month following the later of (A)
the Participant's termination of Employment, or (B) the Participant's 55th
birthday (determined taking into account additional years of age described in
Section 1.2(d)(ii)), or the first day of any month thereafter that is prior to
the Participant's Normal Retirement Date on which the Participant elects to
start payment of his Supplemental Pension.

The election described in (iii) must be made in writing, in a form prescribed by
the Administrator, at least six (6) months before, and in the tax year of the
Participant immediately preceding, the elected benefit start date. Any
Supplemental Pension paid to the Participant commencing prior to Normal
Retirement Date shall equal (I) the amount described in Section 2.1(a) adjusted
for early payment as of the early benefit start date in accordance with Section
6.04 of the Pension Plan (taking into account any additional years of age
described in Section 1.2(d)(ii) for purposes of adjusting both the gross and
offset portions of the benefit except as provided otherwise in Section 2.12),
reduced by (II) the amount described in Section 2.1(b), if any, adjusted for
payment as of the early benefit start date in accordance with Section 6.04 of
the Pension Plan. Notwithstanding the preceding sentence, if the Participant's
Supplemental Pension begins prior to his Pension Plan benefit, the reduction
described in (II) shall be calculated and apply beginning on the earliest date
benefits are payable to the Participant under the Pension Plan, even if the
Participant's Pension Plan benefits do not actually start on that earliest date.

         4.3 Form of Vested Benefit.

                  (a) Benefits Payable Under Supplemental Plan and Pension Plan.
Except as provided in Section 4.4, if a Participant is entitled to benefits
under both the Supplemental Plan and the Pension Plan and benefits under both
Plans start on the same date, the Supplemental Pension determined under Section
4.2 shall be paid in the same form, and shall be subject to the same adjustment
for form of payment and the same Beneficiary designation, as apply to the
Participant's Pension Plan benefit. If, however, such Participant's Supplemental
Plan benefit starts before his Pension Plan benefit, the Participant's
Supplemental Pension will be paid in the form of a single life annuity.

                  (b) No Benefits Payable Under Pension Plan. Except as provided
in Section 4.4, in the event a Participant is entitled to a benefit from the
Supplemental Plan but is not vested in a benefit under the Pension Plan, the
Participant shall receive payment of his Supplemental Pension determined under
Section 4.2 in the automatic form of payment described in Section 8.02 of the
Pension Plan that would have applied to the Participant had he been eligible for
and started payment under the Pension Plan on the same day. The Participant's
Supplemental Pension determined under Section 4.2 shall be adjusted for form of
payment, as appropriate, pursuant to Article VIII of the Pension Plan.

Sections 4.2 and 4.3, above, applied to Supplemental Plan benefits starting
before July 25, 2002, unless the Administrator advised the Participant to the
contrary.

If any employee who is a participant in the Supplemental Pension Plan for Exempt
Salaried Employees of Union Pacific Resources Company and Affiliates is
transferred on or before October 15, 1996 to the Company and becomes a
Participant after such transfer, such employee shall retain no rights in the

transferred on or before October 15, 1996 to an Affiliated Company participating
in the Supplemental Pension Plan for Exempt Salaried Employees of Union Pacific
Resources Company and Affiliates and becomes a participant in the supplemental

                        PRE-RETIREMENT SURVIVOR'S BENEFIT

         6.1 Eligibility. The Surviving Spouse of a Participant who either (a)
terminates Employment or ceases to be a Disabled Participant due to death, or
(b) (i) terminates Employment other than due to death after becoming entitled to
a Supplemental Pension under Article Two or Article Four, and (ii) dies prior to
the commencement of payment of the Supplemental Pension shall receive the
benefit determined pursuant to Section 6.2.

         6.2 Surviving Spouse's Benefit

                  (a) Subsidized Death Benefits.

                           (i) Except as provided in subsection (ii) or Section
6.4, the benefit payable to the Surviving Spouse of a Participant described in
Section 6.1 who dies:

                                    (A) on or after January 1, 1994 while a
Disabled Participant, but before Early or Normal Retirement Date under the terms
of the Pension Plan;

                                    (B) on or after the Effective Date during

Pension Plan; or

                                    (D) on or after the Effective Date after
terminating Employment or ceasing to be a Disabled Participant, providing such
termination or cessation occurred after Early or Normal Retirement Date under
the terms of the Pension Plan,

shall be a monthly annuity payable for the Surviving Spouse's life. Monthly
payments to the Surviving Spouse shall equal one-half of the monthly
Supplemental Pension such Participant would have received (assuming, for a
Participant described in Section 6.1(a), the Participant had vested) in the form
of a single life annuity (in the form of a Qualified Joint and Survivor Annuity
for a Participant described in (B) whose death occurs prior to 1994), if the
Participant had survived (but accrued no additional benefits after death) and
started his Supplemental Pension on the date Supplemental Plan benefits begin to
the Surviving Spouse under Section 6.3. Notwithstanding anything in the
Supplemental Plan to the contrary, the Surviving Spouse's benefit with respect
to a Participant described in (A) or (B), above, shall be determined by
applying, for purposes of any adjustment for payment prior to Normal Retirement
Date, the early retirement reduction factors of Section 6.03 of the Pension
Plan.

                           (ii) Except as provided in Section 6.4, the benefit

Date or who dies under circumstances described in Section 6.2(a)(i) but is
described in Section 6.3(b), shall be an annuity payable for the Surviving
Spouse's life calculated as follows:

                                    (A) In the case of a Participant who is
entitled to both a pension under the Supplemental Plan and a pension under the
Pension Plan, monthly payments to the Surviving Spouse shall equal one-half of
the monthly Supplemental Pension in the form of a single life annuity calculated
for the Participant as described in Section 2.2(b)(i)(A) as if the Participant
had survived (but accrued no additional benefits after death) and started his
Supplemental Pension on the date Supplemental Plan benefits begin to the
Surviving Spouse under Section 6.3, reduced by any survivor benefit that the
Surviving Spouse is entitled to receive from the Pension Plan from the earliest
date on or following the date payments begin to the Surviving Spouse that such
survivor benefit is payable from the Pension Plan (whether or not such survivor
benefit begins on the earliest date under the Pension Plan).

                                    (B) In the case of a Participant who is
entitled to a pension under the Supplemental Plan but is not vested in a pension
under the Pension Plan, monthly payments to the Surviving Spouse shall equal
one-half of the monthly Supplemental Pension in the form of a single life
annuity calculated for the Participant as described in Section 2.2(b)(ii)(A)(I)
as if the Participant had survived (but accrued no additional benefits after
death) and started his Supplemental Pension on the date Supplemental Plan
benefits begin to the Surviving Spouse under Section 6.3.

                  (b) Non-Subsidized Death Benefits. Except as provided in
Section 6.4, the benefit payable to the Surviving Spouse of a Participant
described in Section 6.1 who dies under circumstances other than those described
in Section 6.2(a) shall be an annuity payable for the Surviving Spouse's life
with monthly payments equal to:

                           (i) Prior to the earliest date, if any, on which the
Surviving Spouse is eligible to start any survivor benefit payable under the
Pension Plan, 50% of the monthly Supplemental Pension the Participant would have
received in the form of a Qualified Joint and Survivor Annuity determined as if
the Participant is not entitled to a pension under the Pension Plan if the
Participant had survived (and accrued no additional benefits after his death)
and started his Supplemental Pension on the date Supplemental Plan benefits
begin to the Surviving Spouse under Section 6.3; and

                           (ii) On or after the earliest date, if any, on which
the Surviving Spouse is eligible to start any survivor benefit payable under the
Pension Plan, the amount described in (i), above, reduced by any survivor
benefit that the Surviving Spouse is entitled to receive from the Pension Plan
beginning on such earliest date (whether or not such survivor benefit begins on
the earliest date under the Pension Plan).

         6.3 Timing of Surviving Spouse's Benefit. Except as provided in Section
6.4, the benefit to which a Surviving Spouse of a Participant shall be entitled
pursuant to Section 6.2(a) or (b) shall be paid monthly to such Surviving
Spouse, commencing as of the date such Surviving Spouse elects, or is required
to, start payment of any benefit to which the Surviving Spouse is entitled under
the Pension Plan. Notwithstanding the preceding sentence:


                                       31



                  (a) if the Surviving Spouse is not entitled to any payment
from the Pension Plan, the Surviving Spouse shall receive payment of any
Supplemental Pension to which the Surviving Spouse is entitled under Section 6.2
beginning as of the later of (i) the first of the month following the
Participant's 55th birthday (determined taking into account any additional years
of age described in Section 1.2(d)(ii)), or (ii) the first of the month
following the date of the Participant's death.

                  (b) if the deceased Participant would have been entitled or
required to start his Supplemental Plan benefit on an earlier date than the
Participant would have been entitled to start his Pension Plan benefit had he
survived, the Surviving Spouse shall receive payment of any Supplemental Pension
to which the Surviving Spouse is entitled under Section 6.2 beginning as of the
later of (i) the earliest date as of which the Participant would have been
eligible or required to start payments pursuant to Article Two, Three or Four,
as appropriate, or (ii) the first of the month following the date of the
Participant's death.

Payments to the Surviving Spouse shall end with the payment made for the month
in which the Surviving Spouse dies.

         6.4 Payments Starting Before July 25, 2002. The rules for
pre-retirement death benefits set forth in Sections 6.2 and 6.3, above, applied
to Supplemental Plan pre-retirement death benefits starting before July 25,
2002, unless the Administrator advised the Participant and/or Surviving Spouse
to the contrary.

                                     FUNDING

         7.1 Funding. The Company's obligations hereunder shall constitute a
general, unsecured obligation of the Company payable solely out of its general
assets, and no Participant or former Participant shall have any right to any
specific assets of the Company. To the extent that any Participant or former
Participant acquires a right to receive payments under the Plan, such right
shall be no greater than the right of an unsecured general creditor of the
Company. The Board of Directors of Union Pacific may, but shall not be required
to, authorize Union Pacific to establish a trust to hold assets to be used to
discharge the Company's obligations hereunder, provided that such trust shall
not confer upon Participants or former Participants any rights other than the
rights of unsecured general creditors of the Company.

         7.2 Payment to James Otto. On or about December 1, 2000, James Otto was
paid in a single sum the actuarial equivalent value of the portion of his
Supplemental Pension, payable in the form of a 50% joint and survivor annuity
with his spouse as beneficiary, that was not funded through annuity purchases.
Such single sum payment of $501.40 was in full settlement of the Supplemental
Plan's obligation to pay such remaining benefit to James Otto or his Surviving
Spouse or other beneficiary.

under Section 8.5, incurred by the Administrator and by persons designated by

any other person who is an employee of the Company or an Affiliated Company
shall receive any compensation solely for services in carrying out any
responsibility hereunder.

         8.7 Bonding. No bond or other security shall be required of the
Administrator or of any person designated under Section 8.4.

         8.8 Liability. The Administrator and persons designated by him under
Section 8.4 shall use ordinary care and diligence in the performance of their
duties. The Company shall indemnify and defend the Administrator and each other
person so designated under Section 8.4 against any and all claims, loss,
damages, expense (including reasonable counsel fees), and liability arising from
any action or failure to act or other conduct in their official capacity, except
when the same is due to the gross negligence or willful misconduct of the
Administrator or other persons.

         8.9 Finality of Actions. Any action required of Union Pacific, the
Company, the Board of Directors of Union Pacific, or the Chief Executive Officer
of Union Pacific (the "CEO") under this Supplemental Plan, or made by the

                               GENERAL PROVISIONS

         10.1 Certain Rights Reserved. Nothing herein contained shall confer
upon any Employee or other person the right (a) to continue in Employment or
service of the Company or affect any right that the Company may have to

participation in the Supplemental Plan) any such Employee or other person at any
time for any reason, (b) to participate in the Supplemental Plan, or (c) to
receive an annual base salary of any particular amount.

         10.2 Alienability of Benefits. Payments under the Supplemental Plan may
not be assigned, transferred, pledged or hypothecated, and to the extent
permitted by law, no such payments shall be subject to legal process or
attachment for the payment of any claims against any person entitled to receive
the same. Effective on and after July 25, 2002, compliance with the provisions
and conditions of any domestic relations order relating to an individual's
Supplemental Plan benefits, which the Administrator has determined must be
complied with under the terms of applicable law, shall not be considered a
violation of this provision.

         10.3 Payment Due an Incompetent. If it shall be found that any person
to whom a payment is due hereunder is unable to care for that person's affairs
because of physical or mental disability, as determined by a licensed physician,
the Administrator shall have the authority to cause the payments becoming due
such person to be made to the legally appointed guardian of any such person or
to the spouse, brother, sister, or other person as it shall determine. Payments
made pursuant to such power shall operate as a complete discharge of the
Company's obligations.

         10.4 Governing Law. The Supplemental Plan shall be construed and
enforced in accordance with the laws of the State of Nebraska (without regard to
the legislative or judicial conflict of laws rules of any state), except to the
extent superseded by any federal law.

         10.5 Successors. This Supplemental Plan shall be binding upon any
successor (whether direct or indirect, by purchase, merger, consolidated or
otherwise) to all or substantially all of the business and/or assets of the
Company in the same manner and to the same extent that the Company would be
bound to perform if no such succession had taken place.

         10.6 Titles and Headings Not To Control. The titles and Articles of the
Supplemental Plan and the headings of Sections and subsections of the
Supplemental Plan are placed herein for convenience of reference only and, as
such, shall have no force and effect in the interpretation of the Supplemental
Plan.

         10.7 Severability. If any provisions of the Supplemental Plan shall be
held unlawful or otherwise invalid or unenforceable in whole or in part, the
unlawfulness, invalidity, or unenforceability shall not affect any provision of
the Plan or part thereof, each of which shall remain in full force and effect.

         10.8 Determination and Withholding of Taxes. The Administrator shall
have full authority to satisfy the responsibility of Union Pacific or any
Affiliated Company to withhold taxes with respect to a Participant or former
Participant, including FICA taxes, by withholding such taxes from any
distributions under the Plan to the Participant or former Participant or his
beneficiary or estate. The Administrator shall also have full authority, with or
without the consent of the Participant of former Participant, to withhold from
the individual's compensation from any and all sources, any FICA or other taxes
applicable to benefits accrued under the Supplemental Plan.

the contrary, if a Participant is transferred to the employment of an Affiliated
Company that has not adopted the Supplemental Plan ("non-covered employment"),
upon the approval of the Chief Executive Officer of Union Pacific, any benefits
to which such Participant (or his Surviving Spouse or other beneficiary) would
be entitled under the Pension Plan, the Supplemental Plan, or both, by treating
such Participant's non-covered employment as if it were service covered by such
Plans and by aggregating such service with the Participant's other service

Participant's benefits under the Pension Plan, (b) the Participant's benefits
under the Supplemental Plan determined without regard to this Section 11.1, and
(c) the Participant's benefits under any pension plan of the Affiliated Company

         12.2 Claims Before January 1, 2002. The following provisions are
effective prior to January 1, 2002: In the event that any claim for benefits is
denied in whole or in part, the person whose claim has been so denied shall be

the denial shall specify the reason or reasons for denial, make specific
reference to pertinent provisions of the Supplemental Plan, describe any
additional material or information necessary for the claimant to perfect the
claim (explaining why such material or information is needed), and shall advise
the claimant of the procedure for the appeal of such denial. All appeals shall
be made by the following procedure:

                  (a) The person whose claim has been denied shall file with the
Administrator a notice of desire to appeal the denial. Such notice shall be
filed within 60 days of notification by the Administrator of claim denial, shall
be made in writing, and shall set forth all of the facts upon which the appeal
is based. Appeals not timely filed shall be barred.

                  (b) The Administrator shall consider the merits of the
claimant's written presentations, the merits of any facts or evidence in support
of the denial of benefits, and such other facts and circumstances as the
Administrator shall deem relevant.

                  (c) The Administrator shall ordinarily render a determination
upon the appealed claim within 60 days after receipt which determination shall
be accompanied by a written statement as to the reasons therefor. However, in

may be filed by:

                           (i) any person (or his duly authorized
representative) who has applied for and/or received benefits from the
Supplemental Plan pursuant to Section 12.1 and who believes that the amount
and/or form of benefits provided (including no benefits) or any change in or
termination or reduction of benefits previously provided results in a denial of
benefits to which he is entitled for any reason (whether under the terms of the
Supplemental Plan or by reason of any provision of law); or


                                       40



                           (ii) any Employee or other individual (or his duly
authorized representative) who believes himself to be entitled to benefits from
the Supplemental Plan.

A claim for benefits must be filed with the Administrator, in writing and in
accordance with such other requirements as may be prescribed by the
Administrator. Any claim shall be processed as follows:

                                    (A) When a claim for benefits has been filed
by the claimant (or his duly authorized representative), such claim for benefits
shall be evaluated and the claimant shall be notified by the Administrator of
the approval or denial within a reasonable period of time, but not later than 90
days after the receipt of such claim unless special circumstances require an
extension of time for processing the claim. If such an extension of time for
processing is required, written notice of the extension shall be furnished to
the claimant prior to the termination of the initial 90-day period and shall
specify the special circumstances requiring an extension and the date by which a
final decision will be reached (which date shall not be later than 180 days
after the date on which the claim was received).

                                    (B) A claimant shall be given written notice
in which the claimant shall be advised as to whether the claim is granted or
denied, in whole or in part. If a claim is denied, in whole or in part, the
claimant shall be given written notice which shall contain (I) the specific
reasons for the denial, (II) references to the specific Supplemental Plan
provisions upon which the denial is based, (III) a description of any additional
material or information necessary to perfect the claim and an explanation of why
such material or information is necessary, (IV) a statement that the claimant is
entitled to receive, upon request and free of charge, reasonable access to, and
copies of, all documents, records, and other information relevant to the claim,
(V) the claimant's rights to seek review of the denial and time limits and other
aspects of the Supplemental Plan's claim review procedures, and (VI) a statement
of the claimant's right to bring a civil action under ERISA section 502(a)
following an adverse determination upon review.

                  (b) Review of Claim Denial. If a claim for benefits is denied,
in whole or in part, the claimant (or his duly authorized representative) shall
have the right to request that the Administrator review the denial, provided
that the claimant files in accordance with such requirements as may be
prescribed by the Administrator a written request for review with the
Administrator within 60 days after the date on which the claimant received
written notification of the denial. A claimant (or his duly authorized
representative) may review relevant documents, records and other information
relevant to the claim (or receive copies free of charge) and may submit to the
Administrator with the written request for review documents, records, written
comments and other information relevant to the claim for benefits, which shall
be considered upon review whether or not such information and other items were
available when the claim was originally determined. Requests for review not
timely filed shall be barred. A timely request for claim review shall be
processed as follows:

                           (i) Within a reasonable period of time, but not later
than 60 days after a request for review is received, the review shall be made
and the claimant shall be advised in writing of the decision on review, unless
special circumstances require an extension of time for processing the review. If
an extension is needed, the claimant shall be given a written


                                       41



notification within such initial 60-day period specifying the reasons for the
extension and when such review shall be completed (provided that such review
shall be completed within 120 days after the date on which the request for
review was filed). However, if the period for deciding the claim has been
extended under this paragraph (i) due to a claimant's failure to provide
information necessary to decide a claim, the period for making a decision on
review shall be tolled from the date the claimant is sent written notice of the
extension until the date on which the claimant responds to the request for
information (or such earlier date as may be prescribed by the Administrator in
accordance with applicable law and regulations).

                           (ii) The decision on review shall be forwarded to the
claimant in writing and shall include (A) specific reasons for the decision, (B)
references to the specific Plan provisions upon which the decision is based, (C)
a statement that the claimant is entitled to receive, upon request and free of
charge, reasonable access to, and copies of, all documents, records, and other
information relevant to the claim, and (D) a statement of the claimant's right
to bring an action under ERISA section 502(a). A decision on review shall be
final and binding on all persons for all purposes.

                  (c) Exhaustion of Claims Review Process. A claimant shall have
no right to seek review of a denial of benefits, or to bring any action in any
court to enforce a claim for benefits prior to his filing a claim for benefits
and exhausting his rights to review under this Section 12.3.

         12.4 Claims Related to Corrections Under Pension Plan Compliance
Statement. Notwithstanding any provision of the Supplemental Plan to the
contrary, any individual whose Supplemental Plan benefit is recalculated or
adjusted in connections with corrections made under the Compliance Statement
dated October 25, 2001 (that was issued for the Pension Plan under the Internal
Revenue Service Voluntary Compliance Resolution Program) and who believes that
such recalculation and/or adjustment results in a denial of benefits to which he
is entitled for any reason (whether under the terms of the Supplemental Plan or
by reason of any provision of law) may file a claim with the Administrator, in
writing, stating the reasons he disagrees with such recalculation and/or
adjustment and providing proof of any service, compensation or other facts that
he believes should be taken into account. In order to be considered by the
Supplemental Plan, such written claim and proof must be received by the
Administrator by the date specified in the written notice of such recalculation
and/or adjustment that is sent by the Administrator (or his delegate), by first
class mail, to the person's address reflected in Supplemental Plan records on
the date of the mailing. The deadline for filing a claim under this Section 12.4
that is specified in the written notice from the Administrator shall be a date
not earlier than 90 days after the date such notice is mailed to the person. Any
claim described in this Section 12.4 that is not received by the date specified
in the written notice of recalculation and/or adjustment shall be denied on the
grounds that it is untimely.
