responsibility for that Organizational Unit in consultation with 
the Department.  If the recommendation is not supported by the

resolved by the CEO.  With the appropriate approval of the 
Committee, Eligible Positions may be added throughout the 
calendar year.
     4.3  If after March 1 of a Plan Year, a position is made an 
Eligible Position, an employee occupying such a position shall 
immediately become a Participant and the Department shall prepare 
and submit to the Committee upon request any required 
information.

Section 5:  Variable Compensation Payments
     5.1     The Committee shall determine for each Plan Year the 
amount of the Variable Compensation Payment for each Participant 
included in List A.  The Committee shall make this determination 
with reasonable promptness following the end of a Plan Year.  In 
determining the amount of the Variable Compensation Payment 
granted to each "List A" Participant, there shall be considered 
the extent to which a Participant and such Participant's 
Organizational Unit achieves, during a Plan Year, specific 
internal and external measures of performance established from 
time to time during the Plan Year for the Participant and the 
Participant's Organizational Unit.  Other factors to be 
considered in determining the amount of the Variable Compensation 
Payments granted to Participants are set forth in Sections 5.2, 
5.3 and 5.4 below.
     5.2  The Committee may consider the following factors in 
determining the amount of the Variable Compensation Payment 
granted to the Participant who occupies the position of CEO:  (i) 
the Committee's evaluation of the Corporation's overall financial 
performance during the Plan Year; (ii) the  Corporation's and the 
CEO's achievement of such specific critical internal and external 
measures of performance as were established for the Corporation 
or the CEO, as the case may be, prior to the end of the Plan 
Year, and (iii) the compensation levels of Chief Executive 
Officers, or their equivalent, in companies with whom the 
Corporation compares itself for compensation purposes.
     5.3  The Committee, in consultation with the CEO, may 
consider the following factors in determining the amount of the 
Variable Compensation Payments granted to Participants, other 
than the CEO, who are Eligible Officers:  (i) the Committee's 
evaluation of the overall performance of the Corporation and the 
Eligible Officer during the Plan Year; (ii) the achievement by 
the Eligible Officers or Organizational Units for which the 
respective Eligible Officers are responsible of such specific 
critical measures of performance as were established for such 
Eligible Officers or Organizational Units, as the case may be, 
before the end of the Plan Year, and (iii) the compensation 
levels of officers with comparable responsibility in companies 
with whom the Corporation compares itself for compensation 
purposes.
     5.4  The Variable Compensation Payments for Participants 
other than Eligible Officers shall be determined as follows:  (i) 
the CEO shall determine the aggregate amount to be awarded to 
each Organizational Unit.  That determination shall be based upon 
an evaluation of the performance of the Corporation and those 
Organizational Units during the Plan Year against such specific 
critical measures of performance as were established for such 
Organizational Units before the end of the Plan Year; (ii) the 
Department shall advise the Organizational Units of the total 
Variable Compensation Payments available; (iii) the individual 
Variable Compensation Payments within each Organizational Unit 
(other than for Eligible Officers) shall be determined by 
Organizational Unit management for the approved Participants 
based on the Participant's performance and salary grade level.  
Organizational Unit Variable Compensation Payment totals must be 
within the amounts provided the Organizational Unit by the 
Department.  
     5.5  Variable Compensation Payments shall be payable, at the 
discretion of the Committee, in cash, in Union Carbide common 
stock, Union Carbide restricted stock or a combination  thereof.  
The value of the stock used to satisfy a Variable Compensation 
Payment shall be the average of the high and low prices of Union 
Carbide common stock as reported on the New York Stock Exchange - 
Composite Transactions on the date which is five business days 
before the Variable Compensation Payment is made or on the next 
preceding day such stock was traded on a stock exchange included 
in the New York Stock Exchange - Composite Transactions, if it 
was not traded on any such exchange on the date the Variable 
Compensation Payment is made.

Section 6:  Payment of Variable Compensation Payments
     6.1     The Committee shall normally authorize Variable 
Compensation Payments for a Plan Year to be made on or about 
March 31 following the end of such Plan Year.
     6.2     The Committee reserves the right to delay payment of 
some or all Variable Compensation Payments, in whole or in part, 
upon such terms and conditions as the Committee in its  
discretion may determine.  The Committee's decision regarding the 
delay in a Variable Compensation Payment shall be final and 
binding on all Participants and Beneficiaries.

Section 7:  Termination of Employment
     7.1     If a Participant's employment with the Corporation 
is terminated during a Plan Year, the Committee (with respect to 
any officers of the Corporation), and the Department (with regard 
to all other Participants) shall determine whether the 
Participant shall be entitled to a Variable Compensation Payment 
for such Plan Year and the amount of any such Variable 
Compensation Payment.  
     7.2  A Participant whose employment with the Corporation is 
terminated for any reason shall be deemed to have terminated 
employment with the Corporation on the last day of the month in 
which the termination occurs.

Section 8:  Change of Position During a Plan Year
     8.1     If a Participant is reassigned to a different 
Eligible Position during a Plan Year, then the Variable 
Compensation Payment to such Participant shall be prorated based 
on the number of months and the performance of the Participant in 
each Position.
     8.2  A Participant who is assigned to an Eligible Position 
during a Plan Year, and continues to be a Plan Participant until 
the end of the calendar year, shall receive a Variable 
Compensation Payment based on the number of months and 
Participant's performance in the Position.
     8.3  If a Participant ceases to occupy an Eligible Position 
during a Plan Year and remains employed by the Corporation, then 
the Variable Compensation Payment to such Participant shall equal 
the amount which would have been granted to such Participant had 
such Participant not ceased to occupy an Eligible Position, 
multiplied by a fraction the numerator of which is the number of 
months that such Participant occupied an Eligible Position, and 
the denominator of which is 12.
     8.4  A Participant whose position changes during the Plan 
Year for any reason shall be deemed to have changed position on 
the last day of the month in which such change of position 
occurs.

Section 9:  Beneficiary Designation
     9.1     The beneficiary or beneficiaries designated by the 
Participant or deemed to have been designated by the Participant 
under the Savings Program shall be deemed to be the Participant's 
Beneficiary.  If a Participant does not participate in the 
Savings Program or if a Participant does participate in the 
Savings Program and has not designated or been deemed to have 
designated a beneficiary thereunder, and such Participant dies 
without designating a Beneficiary, then the Variable Compensation 
Payment shall be distributed to the Participant's estate.  If a 
Beneficiary does not survive the Participant, then the 
Participant's Variable Compensation Payment shall be distributed 
to the Participant's estate.  If the Beneficiary of a deceased 
Participant survives the Participant, and dies before such 
Participant's Variable Compensation Payment is distributed, then 
such Variable Compensation Payment shall be distributed to the 
Beneficiary's estate.


Section 10:  General Provisions
     10.1     A Participant may not assign a Variable 
Compensation Payment without the Department's prior written 
consent.  Any attempted assignment without such consent shall be 
null and void.  For purposes of this paragraph, any designation 
of, or payment to, a Beneficiary shall not be deemed an 
assignment.
     10.2     The Plan is intended to constitute an unfunded 
incentive compensation arrangement for a select group of key 
management.  Nothing contained in the Plan, and no action taken 
pursuant to the Plan, shall create or be construed to create a 
trust of any kind.  A Participant's right to receive a Variable 
Compensation Payment shall be no greater than the right of an 
unsecured general creditor of the Corporation.  All Variable 
Compensation Payments shall be paid from the general funds of the 
Corporation, and no special or separate fund shall be established 
and no segregation of assets shall be made to assure payment of 
such Variable Compensation Payments.
     10.3     Nothing contained in the Plan shall give any 
Participant the right to continue in the employment of the 
Corporation, or affect the right of the Corporation to discharge 
a Participant.
     10.4     The Plan shall be construed and governed in 
accordance with the laws of the State of New York.

Section 11:  Amendment, Suspension, or Termination
     11.1     The Board reserves the right to amend, suspend, or 
terminate the Plan at any time; provided, however, that any 
amendment, suspension or termination shall not adversely affect 
the rights of Participants or Beneficiaries to receive Variable 
Compensation Payments granted prior to such action.

Section 12:  Effective Date and Duration of Plan
     The Plan shall be effective beginning as of July 1, 1997 
until and including the date of the annual meeting of 
shareholders of the Corporation in 2002.
