                     SUPPLEMENTAL RETIREMENT

                           INCOME PLAN


              As Amended Through November 30, 1988

               SUPPLEMENTAL RETIREMENT INCOME PLAN

                             General

     This is a supplemental retirement income plan for 
participants in the Retirement Program Plan who are also eligible 
to participate in designated incentive compensation plans of 
Union Carbide Corporation.  This plan has been established 
primarily for the purpose of providing deferred compensation for 
a select group of management or highly compensated employees.  
Specifically, the purpose of this plan is to provide a retirement 
benefit, determined without regard to Code Section 415 or Code 
Section 401(a)(17), equal to the excess of the retirement benefit 
which would be provided by the Retirement Program Plan if (a) 
average monthly compensation included deferred cash bonuses 
awarded under designated incentive compensation plans, and (b) 
all cash bonuses, whether deferred or not, were averaged 
separately from base compensation, and the Equalization Benefit 
Plan, over the retirement benefit actually provided by the 
Retirement Program Plan and the Equalization Benefit Plan.  This 
plan is completely separate from the Retirement Program Plan and 
the Equalization Benefit Plan, is unfunded, and is not qualified 
for special tax treatment under the Internal Revenue Code.
                            ARTICLE I
                           Eligibility
     Section 1.  An employee, or the survivor of an employee who 
has not declined the coverage of a survivor's benefit, will be 
eligible to receive Supplemental Retirement Income under this 
plan, provided that, on or after the date on which this plan is 
approved by the Board of Directors of the Corporation, such 
employee:
     (a)     has received (or has been 
awarded and receipt has been deferred) at 
least one Bonus, and either
     (b)     dies while in the service of the 
Corporation or a subsidiary of the 
Corporation which is then participating in 
the Retirement Program Plan, provided that 
such employee's survivor is eligible to 
receive a survivor's benefit under the 
Retirement Program Plan, or
     (c)     termination from employment with 
the Corporation or said subsidiary and is 
eligible to receive a pension benefit or a 
disability benefit under the Retirement 
Program Plan.
     Section 2.  An employee, or the survivor of an employee who 
has not declined the coverage of a survivor's benefit, will also 
be eligible to receive Supplemental Retirement Income under this 
plan if such employee receives compensation in excess of the 
compensation which may be considered by the Retirement Program 
Plan under Code Section 401(a)(17).
                           ARTICLE II
            Amount of Supplemental Retirement Income
     Section 1.  The monthly amount of Supplemental Retirement 
Income payable to an employee will be the excess, if any, of (1) 
the employee's monthly retirement income, as determined under 
section 2, over (2) the employee's monthly pension under the 
Retirement Program Plan and the Equalization Plan.
     Section 2.  The amount of monthly retirement income payable 
to an eligible employee shall be computed by using the applicable 
formula provided in Article V of the Retirement Program Plan 
except that average monthly compensation shall for this purpose 
be equal to an amount determined under section 3 of Article II of 
this plan, and shall be determined without regard to the 
limitation of Code Section 401(a)(17).
     Section 3.  An employee's average monthly compensation shall 
be computed in the following manner:
     (a)     For employees who retire or die 
prior to April 27, 1983, average monthly 
compensation shall be computed by taking the 
larger of:
          (i)     1/36 of base salary 
and Bonuses related to the three full 
calendar years in which these combined 
amounts were largest during the 10 full 
calendar years next preceding the date 
of death or retirement or
          (ii)     1/36 of the sum of 
(a) the base salary for the 36 full 
calendar months next preceding the date 
of death or retirement; provided that 
for purposes of this calculation the 
base salary received in any calendar 
month within the third preceding 
calendar year shall be the total 
compensation received in such year 
divided by the number of months worked 
in such year and (b) the Bonuses related 
to the three full calendar years next 
preceding the date of death or 
retirement.
     (b)     For employees who retire or die 
on or after April 27, 1983, but prior to 
February 22, 1984, average monthly 
compensation shall be computed by determining 
the sum of the following amounts:
          (i)     the larger of:
                    (I)  1/36 of base 
salary related to the three full 
calendar years in which such salary was 
largest during the 10 full calendar 
years next preceding the date of death 
or retirement or
                    (II)  1/36 of base 
salary for the 36 full calendar months 
next preceding the date of death or 
retirement calculated in the manner 
described under Section 3(a)(ii) above; 
and
          (ii)     1/36 of the 
employee's Bonuses related to the three 
full calendar years in which such 
Bonuses were the largest during the five 
full calendar years next preceding the 
date of death or retirement;
          provided, that if it would 
produce a larger benefit under the plan, 
then payments under the plan shall be 
computed in accordance with subpart (a) 
of this Section for any participant who 
received a Bonus related to a year prior 
to 1983 who dies or retires prior to 
January 1, 1993.
     (c)     For employees who retire or die 
on or after February 22, 1984, average 
monthly compensation shall be computed by 
determining the sum of the following amounts 
(or shall be computed in accordance with 
subpart (a) of this Section if an employee is 
eligible for such computation and such 
computation produces a larger benefit under 
the plan):
          (i)     the larger of:
                    (I)  1/36 of base 
salary related to the three full 
calendar years in which such salary was 
largest during the 10 full calendar 
years next preceding the date of death 
or retirement or
                    (II)  1/36 of base 
salary for the 36 full calendar months 
next preceding the date of death or 
retirement calculated in the manner 
described under Section 3(a)(ii) above; 
and
          (ii)     1/36 of the 
employee's Bonuses related to the three 
full calendar years in which such 
Bonuses were the largest during the 10 
full calendar years next preceding the 
date of death or retirement provided, 
that for an employee retiring on or 
after January 1, 1988, the calendar 
years in which the employee was hired or 
terminates employment shall each be 
considered a full calendar year for the 
purposes of this clause (ii).
     (d)     For purposes of the calculations 
under subparts (a), (b) and (c) of this 
Section, a Bonus will be related to the 
calendar year in which an employee performed 
the services for which the Bonus was paid 
irrespective of the calendar year in which 
the Bonus was awarded or paid.  For purposes 
of the calculations under subparts (a), (b) 
and (c) of this Section, the amount of base 
salary received in any calendar month will be 
calculated in the same manner in which 
average monthly compensation used to compute 
pension benefits under the Retirement Program 
Plan is calculated (determined without regard 
to Incentive Compensation as defined 
therein).
     Section 4.  If the Supplemental Retirement Income payable to 
an employee under this plan commences before the award to such 
employee of a Bonus (whether or not paid) which may be used to 
determine average monthly compensation under Section 3 of this 
Article II, the monthly amount of Supplemental Retirement Income 
payable hereunder shall be recalculated after such Bonus is 
awarded (whether or not paid).  The monthly amount of 
Supplemental Retirement Income resulting from said recalculation 
shall be paid commencing in or before the third calendar month 
after the month in which such Bonus is awarded, provided that the 
first monthly payment of such recalculated Supplemental 
Retirement Income shall be increased to reflect any prior 
underpayment of Supplemental Retirement Income resulting from the 
failure to include such Bonus in the initial calculation of 
Supplemental Retirement Income.
     Section 5.  For purposes of calculating the amount of an 
employee's Supplemental Retirement Income pursuant to Section 1 
of this Article II, the amount of an employee's monthly 
retirement income and monthly pension under the Retirement 
Program Plan and the Equalization Benefit Plan shall be 
determined without any adjustment on account of (i) a Survivor's 
Benefit or (ii) an election to receive level retirement income.
     Section 6.  If an employee does not decline the coverage of 
a survivor's benefit, the monthly amount of Supplemental 
Retirement Income which such employee would otherwise have 
received shall be reduced by applying the same factor used in the 
Retirement Program Plan in connection with survivor's benefits. 
     Section 7.  The monthly amount of Supplemental Retirement 
Income payable to the eligible survivor of an employee shall be 
calculated in the same manner that such survivor's benefit is 
calculated under the Retirement Program Plan.
                           ARTICLE III
                             Vesting
     Section 1.  Subject to Section 4 of Article IV, an employee 
will be vested in such employee's right to receive Supplemental 
Retirement Income under the plan in the same manner and to the 
same extent as provided under the Retirement Program Plan.  Once 
an employee has become vested, all of such employee's rights to 
receive Supplemental Retirement Income under this Plan shall be 
nonforfeitable.
                           ARTICLE IV
                            Payments
     Section 1.  Supplemental Retirement Income shall be paid 
monthly to an employee or his survivor commencing with the month 
such employee or his survivor commence benefits under the 
Retirement Program Plan, and shall cease or be suspended at the 
same time the employee or his survivor cease or have suspended 
benefits under the Retirement Program Plan.  However, 
Supplemental Retirement Income shall in no event be payable after 
the death of an employee who has declined the coverage of a 
survivor's benefit.
     Section 2.  Unless otherwise elected, Supplemental 
Retirement Income payable under this plan shall include the 
coverage of a survivor's benefit.  A survivor's benefit payable 
from this plan shall be paid to that person designated to receive 
a survivor's benefit under the Retirement Program Plan.
     Section 3.  Supplemental Retirement Income shall be received 
in the same form, and with the same actuarial adjustments, as the 
participant is receiving distributions from the Retirement 
Program Plan.
     Section 4.  If the Compensation and Management Development 
Committee of the Board of Directors determines, after a hearing, 
that an employee who is eligible to receive or is receiving 
Supplemental Retirement Income has engaged in any activities 
which, in the opinion of that Committee, are detrimental to the 
interests of, or are in competition with, this Corporation or any 
of its subsidiaries, such Supplemental Retirement Income shall 
thereupon be terminated.

employee whose rights have vested.
