Mr. R. Van Mynen
P2-607



Dear Ron:

     The Board of Directors (the "Board") of Union Carbide 
Corporation (the "Corporation") recognizes that the possibility of 
a change in control of the Corporation exists, as is the case with 
many publicly held corporations, and the uncertainty and questions 
which it may raise among management may result in the departure or 
distraction of management personnel to the detriment of the 
Corporation and its stockholders.

     The Board has determined that appropriate steps should be 
taken to reinforce and encourage the continued attention and 
dedication of members of the Corporation's management, including 
yourself, to their assigned duties without distraction in the face 
of potentially disturbing circumstances arising from a possible 
change in control of the Corporation. The Board has also 
determined that it is in the best interests of the Corporation and 
its stockholders to ensure your continued availability to the 
Corporation in the event of a potential change in control of the 
Corporation.

     In order to induce you to remain in the employ of the 
Corporation and in consideration of your agreement set forth in 
Paragraph 2 hereof, the Corporation agrees that you shall receive 
the severance benefits set forth in this letter agreement 
("Agreement") in the event your employment with the Corporation is 
terminated subsequent to a change in control under the 
circumstances described below.

1.   Definitions.

     a.  "Change in Control" of the Corporation shall be deemed to 
occur if any of the following circumstances shall occur:

          (i)  if a change in control of the Corporation would be 
     required to be reported in response to Item 1(a) of the 
     Current Report on Form 8-K, as in effect on the date hereof, 
     pursuant to Section 13 or 15(d) of the Securities Exchange 
     Act of 1934, as amended (the "Act"), whether or not the 
     Corporation is then subject to such reporting requirement;

         (ii)  there shall be consummated (x) any consolidation 
     or merger of the Corporation in which the Corporation is not 
     the continuing or surviving corporation or pursuant to which 
     shares of the Corporation's Common Stock would be converted 
     into cash, securities or other property, other than a merger 
     of the Corporation in which the holders of the Corporation's 
     Common Stock immediately prior to the merger have the same 
     proportion and ownership of common stock of the surviving 
     corporation immediately after the merger, or (y) any sale, 
     lease, exchange or other transfer (in one transaction or a 
     series of related transactions) of all, or substantially all, 
     of the assets of the Corporation, provided, that the 
     divestiture of less than substantially all of the assets of 
     the Corporation in one transaction or a series of related 
     transactions, whether effected by sale, lease, exchange, 
     spin-off, sale of the stock or merger of a subsidiary or 
     otherwise, shall not constitute a Change in Control;

        (iii)  any "person" or "group" within the meaning of 
     Sections 13(d) and 14(d)(2) of the Act (x) becomes the 
     "beneficial owner" as defined in Rule 13d-3 under the Act of 
     more than 20% of the then outstanding voting securities of 
     the Corporation, otherwise than through a transaction or 
     transactions arranged by, or consummated with the prior 
     approval of, the Board, or (y) acquires by proxy or otherwise 
     the right to vote for the election of directors, for any 
     merger or consolidation of the Corporation or for any other 
     matter or question more than 20% of the then outstanding 
     voting securities of the Corporation, otherwise than through 
     an arrangement or arrangements consummated with the prior 
     approval of the Board;

         (iv)  if during any period of twenty-four consecutive 
     months (not including any period prior to the date of this 
     Agreement), Present Directors and/or New Directors cease for 
     any reason to constitute a majority of the Board. For 
     purposes of the preceding sentence, "Present Directors" shall 
     mean individuals who at the beginning of such consecutive 
     twenty-four month period were members of the Board and "New 
     Directors" shall mean any director whose election by the 
     Board or whose nomination for election by the Corporation's 
     stockholders was approved by a vote of at least two-thirds of 
     the Directors then still in office who were Present Directors 
     or New Directors.

     b.  "Date of Termination" shall mean:

          (i)  in case employment is terminated for Total 
     Disability, thirty (30) days after Notice of Termination is 
     given (provided that you shall not have returned to the full-
     time performance of your duties during such thirty (30) day 
     period), and

         (ii)  in all other cases, the date specified in the 
     Notice of Termination (which shall not be less than thirty 
     (30) nor more than sixty (60) days, respectively, from the 
     date such Notice of Termination is given),

        (iii)  provided that if within thirty (30) days after any 
     Notice of Termination is given, the party receiving the 
     Notice advises the other party that a dispute exists 
     concerning the termination, the Date of Termination shall be 
     the date on which the dispute is finally resolved, either by 
     mutual written agreement of the parties, or by a final 
     judgment, order or decree of a court of competent 
     jurisdiction (which is not appealable or the time for appeal 
     therefrom having expired and no appeal having been 
     perfected); provided further that the Date of Termination 
     shall be extended by a notice of dispute only if such notice 
     is given in good faith and the party giving such notice 
     pursues the resolution of such dispute with reasonable 
     diligence.

     c.  "Total Disability" shall mean total and permanent 
physical or mental disability to perform any work for compensation 
in any occupation or position. Any question as to the existence of 
your Total Disability upon which you and the Corporation cannot 
agree shall be determined by a qualified physician not employed by 
the Corporation and selected by you (or, if you are unable to make 
such selection, it shall be made by any adult member of your 
immediate family), and approved by the Corporation. The 
determination of such physician made in writing to the Corporation 
and to you shall be final and conclusive for all purposes of this 
Agreement.

     d.  "Good Reason for Resignation" shall mean, without your 
express written consent, any of the following:

          (i)  a change in your status or position with the 
     Corporation which in your reasonable judgment does not 
     represent a promotion from your status or position 
     immediately prior to the Change in Control, or the assignment 
     to you of any duties or responsibilities which in your 
     reasonable judgment are inconsistent with your status as an 
     employee of the Corporation in effect immediately prior to 
     the Change in Control, it being understood that any of the 
     foregoing in connection with termination of your employment 
     for Cause, Retirement, or Total Disability shall not 
     constitute Good Reason for Resignation; 

         (ii)  a reduction by the Corporation in the annual rate 
     of your base salary as in effect immediately prior to the 
     date of a Change of Control or as the same may be increased 
     from time to time thereafter, or the Corporation's failure to 
     increase the annual rate of your base salary in an amount at 
     least equal to the average percentage increase in base salary 
     for all officers of the Corporation in the preceding 12 
     months;

        (iii)  the relocation of the Corporation's principal 
     executive offices to a location more than thirty-five miles 
     from Danbury, Connecticut or the Corporation's requiring you 
     to be based anywhere other than the Corporation's principal 
     executive offices (or, if you were not based at the 
     Corporation's principal executive offices immediately prior 
     to a Change in Control, the Corporation's requiring you to be 
     based anywhere other than where your office is located 
     immediately prior to such Change in Control) except for 
     required travel on the Corporation's business to an extent 
     substantially consistent with your business travel 
     obligations immediately prior to a Change in Control;

         (iv)  the failure by the Corporation to continue in 
     effect any compensation plan in which you participate as in 
     effect immediately prior to the Change in Control, including 
     but not limited to the Retirement Program, the Savings 
     Program and the Incentive Compensation Plans, or any 
     substitute plans adopted prior to the Change in Control, 
     unless an arrangement satisfactory to you (embodied in an 
     ongoing substitute or alternative plan) has been made with 
     respect to such plan, or the failure by the Corporation to 
     continue your participation therein on at least as favorable 
     a basis, both in terms of the amount of benefits provided and 
     the level of your participation relative to other 
     participants, as existed immediately prior to the Change in 
     Control;

          (v)  the failure by the Corporation to continue to 
     provide you with benefits at least as favorable as those 
     enjoyed by you under any of the Corporation's pre-retirement 
     and post-retirement life insurance, medical, health and 
     accident, and disability plans or any other plan, program or 
     policy of the Corporation intended to benefit employees in 
     which you were participating immediately prior to the Change 
     in Control, the taking of any action by the Corporation which 
     would directly or indirectly materially reduce any of such 
     benefits or deprive you of any material fringe benefit 
     enjoyed by you immediately prior to the Change in Control, or 
     the failure by the Corporation to provide you with the number 
     of annual paid vacation days to which you were annually 
     entitled immediately prior to the Change in Control;

         (vi)  the failure of the Corporation to obtain a 
     satisfactory agreement from any Successor (as defined in 
     Paragraph 5a hereof) to assume and agree to perform this 
     Agreement, as contemplated in Paragraph 5a hereof; or

        (vii)  any purported termination of your employment which 
     is not effected pursuant to a Notice of Termination 
     satisfying the requirements hereof; for purposes of this 
     Agreement, no such purported termination shall be effective 
     for any purpose except to constitute a Good Reason for 
     Resignation.

     e.  "Incentive Compensation Plans" shall mean:

          (i)  the 1989 Bonus Plan

         (ii)  the 1988 Long-Term Incentive Plan

        (iii)  the 1984 UCC Cash Bonus Plan

         (iv)  the 1983 UCC Bonus Deferral Program

          (v)  the 1984 UCC Bonus Deferral Plan

         (vi)  the 1984 UCC Stock Option Plan

        (vii)  the 1979 UCC Incentive Compensation Plan, and

       (viii)  dividend equivalents under the 1959 UCC Incentive 
     Plan

     f.  "Potential Change in Control of the Corporation" shall be 
deemed to have occurred if:

          (i)  the Corporation enters into an agreement, the 
     consummation of which would result in the occurrence of a 
     Change in Control;

         (ii)  any person (including any individual, corporation, 
     partnership, group, association or other "person", as such 
     term is used in Section 14(d) of the Act, including the 
     Corporation) publicly announces an intention to take actions 
     which if consummated would constitute a Change in Control;

        (iii)  any person as defined above becomes the beneficial 
     owner, directly or indirectly, of securities of the 
     Corporation representing 9.5 percent or more of the combined 
     voting power of the Corporation's then outstanding 
     securities; or

         (iv)  the Board adopts a resolution to the effect that, 
     for purposes of this Agreement, a Potential Change in Control 
     of the Corporation has occurred.

     g.  "Notice of Termination" shall mean a written notice as 
provided in Paragraph 9 hereof.

     h.  "Retirement" shall mean (1) voluntary retirement before 
your mandatory retirement age with an immediate, nonactuarially-
reduced pension under the Corporation's Retirement Program 
(termination of your employment by you before your mandatory 
retirement age with Good Reason for Resignation shall not be 
deemed a Retirement for purposes of this Agreement even though you 
are eligible for and elect to receive an immediate, 
nonactuarially-reduced pension under the Corporation's Retirement 
Program) or (2) termination in accordance with any retirement 
arrangement other than under the Corporation's Retirement Program, 
which is established with your consent with respect to you or (3) 
mandatory retirement under the Corporation's Retirement Program.

     i.  "Retirement Program" shall mean:

          (i)  the Retirement Program Plan for Employees of Union 
     Carbide Corporation and its Participating Subsidiaries;

         (ii)  the Equalization Benefit Plan for Participants of 
     The Retirement Program Plan; and

        (iii)  the Supplemental Retirement Income Plan.

     j.  "Savings Program" shall mean:

          (i)  the Savings Plan for Employees of Union Carbide 
     Corporation and Participating Subsidiary Companies; and

         (ii)  the 401(k) Opportunity Plan for Salaried Employees 
     of Union Carbide Corporation.

     k.  "Termination for Cause" shall mean termination of your 
employment upon:

          (i)  your willful and continued failure to substantially 
     perform your duties with the Corporation (other than any such 
     failure resulting from your Total Disability or any such 
     actual or anticipated failure resulting from your resignation 
     with Good Reason for Resignation) after a written demand for 
     substantial performance is delivered to you by the Board, 
     which demand specifically identifies the manner in which the 
     Board believes that you have not substantially performed your 
     duties, or

         (ii)  your willfully engaging in conduct demonstrably 
     and materially injurious to the Corporation, monetarily or 
     otherwise,

but only so long as there shall have been delivered to you a copy 
of a resolution duly adopted by the affirmative vote of not less 
than three-quarters (3/4) of the entire membership of the Board at 
a meeting of the Board called and held for such purpose (after 
reasonable notice to you and an opportunity for you, together with 
your counsel, to be heard before the Board), finding that in the 
good faith opinion of the Board you were guilty of conduct set 
forth and specifying the particulars thereof in detail.

For purposes of this Paragraph 1k, no act, or failure to act, on 
your part shall be deemed "willful" unless done, or omitted to be 
done, by you not in good faith and without reasonable belief that 
your action or omission was in the best interest of the 
Corporation. Any act or failure to act based upon authority given 
pursuant to a resolution duly adopted by the Board or based upon 
the advice of counsel for the Corporation shall be conclusively 
presumed to be done or omitted to be done by you in good faith and 
in the best interests of the Corporation.

2.  Agreement to Remain Employed.  You agree that, subject to the 
terms and conditions of this Agreement, you will remain in the 
employ of the Corporation and continue to render the services 
contemplated in the recitals to this Agreement (except for Total 
Disability or Retirement or resignation with Good Reason for 
Resignation) for a period of six (6) months from the date of this 
Agreement. If a Potential Change in Control of the Corporation 
occurs during the term of this Agreement, you will remain in the 
employ of the Corporation and continue to render such services for 
a period of six (6) months after the occurrence of each such 
Potential Change in Control of the Corporation occurring prior to 
the occurrence of a Change in Control.

3.   Compensation Upon Termination or While Disabled.  Following a 
Change in Control of the Corporation you shall be entitled to the 
following benefits:

     a.  Termination Other Than for Cause, Retirement, Death or 
Total Disability; Termination By Your Resignation with Good Reason 
for Resignation.  If your employment by the Corporation shall be 
terminated subsequent to the Change in Control and during the term 
of this Agreement (a) by the Corporation other than for Cause, 
Retirement, Death or Disability or (b) by you for Good Reason for 
Resignation, then you shall be entitled to the benefits provided 
below, without regard to any contrary provision of any plan:

          (i)  Accrued Salary. The Corporation shall pay you, in a 
     lump sum in cash, not later than the fifth day following the 
     Date of Termination your full base salary and vacation pay 
     accrued through the Date of Termination at the rate in effect 
     at the time the Notice of Termination is given (or at the 
     rate in effect immediately prior to a Change in Control, if 
     such amounts were higher).

         (ii)  Accrued Incentive Compensation. If the Date of 
     Termination is after a Bonus Year, but before Incentive 
     Compensation for said Bonus Year has been paid, the 
     Corporation shall pay you as Incentive Compensation for that 
     Bonus Year, the greater of (x) the amount of Incentive 
     Compensation awarded or determined to be awarded to you by 
     the Board for that Bonus Year, or (y) an amount that bears 
     the same ratio to your total base salary in said Bonus Year 
     as the total of all Incentive Compensation paid to 
     participants in the Incentive Compensation Program for said 
     Bonus Year bears to the total of all base salaries paid to 
     said participants in said Bonus Year, such payment to you to 
     be made at the same time the Corporation pays Incentive 
     Compensation for said Bonus Year under the applicable 
     Incentive Compensation Program. In addition, if the Date of 
     Termination is other than the first day of a Bonus Year, the 
     Corporation shall pay you, as Incentive Compensation for the 
     Bonus Year in which the Date of Termination occurs, the 
     greater of (x) the amount of incentive compensation awarded 
     or determined to be awarded to you by the Board for that 
     Bonus Year, or (y) an amount that bears the same ratio to 
     your total base salary in said Bonus Year as the total of all 
     Incentive Compensation paid to participants in the Incentive 
     Program for said Bonus Year bears to the total of all base 
     salaries paid to said participants in said Bonus Year, such 
     payment to you to be made at the same time the Corporation 
     pays Incentive Compensation for said Bonus Year under the 
     applicable Incentive Compensation Program. If there is more 
     than one Incentive Compensation Program, your accrued 
     Incentive Compensation under each Program shall be determined 
     individually for that Program. For the purpose of this 
     Paragraph 3(a)(ii), "Incentive Compensation Program" means 
     any of the Incentive Compensation Plans defined in Paragraph 
     1e and any other plan or program for the payment of 
     incentive compensation, bonus, benefits or awards for which 
     you were, or your position was, eligible to participate; 
     "Incentive Compensation" means any compensation, bonus, 
     benefit or award paid or payable under an Incentive 
     Compensation Program; "Bonus Year" means a calendar year of 
     an Incentive Compensation Program, and "Board" means the 
     Board of Directors of the Corporation, any committee of the 
     Board of Directors or any person or group designated by the 
     Board of Directors to determine the amount of Incentive 
     Compensation payable under an Incentive Compensation Program.

        (iii)  Insurance Coverage. The Corporation shall 
     arrange to provide you with life, disability, accident and 
     health insurance benefits substantially similar to those 
     which you are receiving or entitled to receive immediately 
     prior to the Change in Control of the Corporation. Such 
     insurance benefits shall be provided to you for the longer of 
     (x) twenty-four (24) months after such Date of Termination or 
     (y) the period during which such insurance benefits would 
     have been provided to you under the applicable life 
     insurance, medical, health and accident and disability 
     insurance plans of the Corporation in effect immediately 
     prior to the Change in Control of the Corporation.

         (iv)  Retirement Benefits. The Corporation shall pay you, 
     at the time you are entitled to be paid a retirement pension 
     under the Retirement Program, a retirement pension equal to 
     the greater of (x) an amount computed in accordance with the 
     terms of the Retirement Program in effect immediately prior 
     to the Change in Control of the Corporation and as if those 
     terms were in effect on the Date of Termination, or (y) an 
     amount computed in accordance with the terms of the 
     Retirement Program in effect immediately prior to the Date of 
     Termination, in either case less the amount of retirement 
     pension actually to be paid to you under the Retirement 
     Program. In computing the amounts of your retirement pension 
     under clauses (x) and (y) of this Paragraph 3a(iv), to the 
     extent such benefits are payable under the tax qualified 
     Retirement Program Plan for Employees of Union Carbide 
     Corporation and its Participating Subsidiaries, three years 
     shall be added to your actual age and to your actual Company 
     Service Credit under the Retirement Program Plan for 
     Employees of Union Carbide Corporation and its Participating 
     Subsidiaries so that your retirement pension under clauses 
     (x) and (y) will be the amount it would have been if you had 
     been three years older than you actually were, and had three 
     years more Company Service Credit than you actually had, on 
     the Date of Termination.

          (v)   Severance Payment. The Corporation shall pay as 
     severance pay to you, not later than the fifth day following 
     the Date of Termination, a lump sum severance payment (the 
     "Severance Payment") equal to 2.99 times the average of the 
     annual compensation which was payable to you by the 
     Corporation (or any corporation affiliated with the 
     Corporation within the meaning of section 1504 of the 
     Internal Revenue Code of 1954, as amended ("Code")) and 
     includible in your gross income for Federal income tax 
     purposes for the five calendar years (the "Base Period") 
     preceding the calendar year in which a Change in Control of 
     the Corporation occurred. The Severance Payment shall be 
     reduced pursuant to Paragraph 3a(vi) hereof to the extent the 
     Corporation could not properly deduct amounts paid pursuant 
     to Paragraph 3a(i) through 3a(iv) hereof or otherwise 
     pursuant to section 280G of the Code. For purposes hereunder, 
     the average annual compensation shall be determined in 
     accordance with proposed, temporary or final regulations 
     promulgated under section 280G(d) of the Code. Compensation 
     payable to you by the Corporation (or an affiliate) shall 
     include every type and form of compensation includible in 
     your gross income in respect of your employment by the 
     Corporation (or an affiliate), including but not limited to 
     compensation income recognized as a result of your exercise 
     of stock options or sale of the stock so acquired, bonuses, 
     dividend equivalents, fringe benefits, relocation payments, 
     and stock appreciation rights, except to the extent otherwise 
     provided in proposed, temporary or final regulations 
     promulgated under section 280G(d) of the Code. For purposes 
     of Paragraphs 3a(v) and 3a(vi) only, a "Change in control of 
     the Corporation" shall have the meaning set forth in section 
     280G(d) of the Code and any proposed, temporary or final 
     regulations promulgated thereunder.

         (vi)  Reduction in Severance Payment. The Severance 
     Payment shall be reduced but not below zero by the amount of 
     any other payment or the value of any benefit received or to 
     be received by you contingent upon a Change in Control of the 
     Corporation (whether payable pursuant to the terms of this 
     Agreement, any other plan, agreement or arrangement with the 
     Corporation or an affiliate) unless (1) you shall have 
     effectively waived your receipt or enjoyment of such payment 
     or benefit prior to the date of payment of the Severance 
     Payment, or (2) in the opinion of Messrs. Kelley Drye & 
     Warren, which shall be binding upon the Corporation and upon 
     you, such other payment or benefit plus the Severance Payment 
     (in its full amount or as partially reduced hereunder, as the 
     case may be) would be properly deductible by the Corporation 
     without restriction pursuant to Code section 280G. The value 
     of any non-cash benefit or any deferred cash payment shall 
     promptly be determined by the Corporation's independent 
     auditors in accordance with the principles of sections 
     280G(d)(3) and (4) of the Code.

        (vii)  Repayment of excess payment. If it is established 
     pursuant to a final determination of a court or an Internal 
     Revenue Service proceeding that, notwithstanding the good 
     faith of you and the Corporation in applying the terms of 
     this Paragraph 3a, the aggregate payments hereunder to or for 
     your benefit would result in any portion of such payments not 
     being deductible by the Corporation or its affiliates by 
     reason of section 280G of the Code, then you agree to pay the 
     Corporation upon demand an amount equal to the sum of (1) the 
     excess of the aggregate payments hereunder paid to or for 
     your benefit over the aggregate payments hereunder that would 
     have been paid to or for your benefit without any portion of 
     such payments not being deductible by reason of section 280G 
     of the Code; and (2) interest on the amount set forth in 
     clause (1) of this sentence at the applicable Federal rate 
     (as defined in section 1274(d) of the Code) from the date of 
     your receipt of such excess until the date of such payment. 
     No amount shall be payable by you hereunder if and to the 
     extent that in the opinion of Messrs. Kelley Drye & Warren 
     such repayment would not reduce the amount of payments to you 
     which are considered nondeductible by the Corporation 
     pursuant to Code section 280G.

       (viii)  No duty to mitigate. You shall not be required to 
     mitigate the amount of any payment provided for in this 
     Paragraph 3 by seeking other employment or otherwise, nor 
     shall the amount of any payment or benefit as provided for be 
     reduced by any compensation earned by you as the result of 
     employment by another employer or by retirement benefits 
     after the Date of Termination, or otherwise except as 
     specifically provided herein.

     b.  Payments While Disabled. During any period prior to the 
Date of Termination and during the term of this Agreement that you 
are unable to perform your full-time duties with the Corporation, 
whether as a result of your Total Disability or as a result of a 
physical or mental disability that is not total or is not 
permanent and therefore is not a Total Disability, you shall 
continue to receive your base salary at the rate in effect at the 
commencement of any such period, together with all other 
compensation and benefits that are payable under the Corporation's 
disability benefit plans. After the Date of Termination, your 
benefits shall be determined in accordance with the Corporation's 
Retirement Program, insurance and other applicable programs. The 
compensation and benefits, other than salary, payable pursuant to 
this Paragraph 3b shall be the greater of (x) the amounts computed 
under the Retirement Program, disability benefit plans, insurance 
and other applicable programs in effect immediately prior to a 
Change in Control of the Corporation, and (y) the amounts computed 
under the Retirement Program, disability benefit plans, insurance 
and other applicable programs in effect at the time the 
compensation and benefits are paid.

     c.  Payments if Terminated for Cause, or by You Except With 
Good Reason. If your employment shall be terminated by the 
Corporation for Cause or by you other than with Good Reason for 
Resignation, the Corporation shall pay you your full base salary 
then in effect through the Date of Termination, at the rate in 
effect at the time Notice of Termination is given plus any 
benefits or awards which have been earned or become payable but 
which have not yet been paid to you. Thereafter the Corporation 
shall have no further obligation to you under this Agreement.

     d.  After Retirement or Death. If your employment shall be 
terminated by your Retirement, or by reason of your death, your 
benefits shall be determined in accordance with the Corporation's 
retirement and insurance programs then in effect.

4.   Term of Agreement.  This Agreement shall commence on the date 
hereof and shall continue in effect through December 31, 1992; 
provided, however, that commencing on January 1, 1993 and each 
January 1 thereafter, the term of this Agreement shall 
automatically be extended for one additional year unless, not 
later than September 30 of the preceding year, the Corporation or 
you shall have given notice that it or you do not wish to extend 
this Agreement; provided, further, that notwithstanding any such 
notice by the Corporation or you not to extend, if a Change in 
Control shall have occurred during the original or extended term 
of this Agreement, this Agreement shall continue in effect for a 
period of twenty-four (24) months beyond the term in effect 
immediately before such Change in Control. This Agreement shall 
terminate if your employment is terminated by you or the 
Corporation prior to a Change in Control.

5.   Successors; Binding Agreement.

     a.  Successors of the Corporation. The Corporation will 
require any Successor to all or substantially all of the business 
and/or assets of the Corporation to expressly assume and agree, by 
an agreement in form and substance satisfactory to you, to perform 
this Agreement in the same manner and to the same extent that the 
Corporation would be required to perform it if no such succession 
had taken place. Failure of the Corporation to obtain such assent 
at least five business days prior to the time a person becomes a 
Successor (or where the Corporation does not have at least five 
business days advance notice that a person may become a Successor, 
within three business days after having notice that such person 
may become or has become a Successor) shall constitute Good Reason 
for Resignation by you and, if a Change in Control of the 
Corporation has occurred or thereafter occurs, shall entitle you 
immediately to the benefits provided in Paragraph 3a hereof upon 
delivery by you of a Notice of Termination which the Corporation, 
by executing this Agreement hereby assents to. For purposes of 
this Agreement, "Successor" shall mean any person that obtains or 
succeeds to, or has the practical ability to control (either 
immediately or with the passage of time), the Corporation's 
business directly, by merger or consolidation, or indirectly, by 
purchase of voting securities of the Corporation, by acquisition 
of rights to vote voting securities of the Corporation or 
otherwise, including but not limited to any person or group that 
acquires the beneficial ownership or voting rights described in 
Paragraph 1a(iii) and any person or group required to be 
identified in a Current Report on Form 8-K described in Paragraph 
1a(i).

     b.  Your Successor.  This Agreement shall inure to the 
benefit of and be enforceable by your personal or legal 
representatives, executors, administrators, successors, heirs, 
distributees, devisees and legatees. If you should die while any 
amount would still be payable to you hereunder if you had 
continued to live, all such amounts, unless otherwise provided 
herein, shall be paid in accordance with the terms of this 
Agreement to your devisee, legatee or other designee or, if there 
is no such designee, to your estate.

6.   Relationship to Other Agreements.  To the extent that any 
provision of any other agreement between the Corporation or any of 
its subsidiaries and you shall limit, qualify or be inconsistent 
with any provision of this Agreement, then for purposes of this 
Agreement, while the same shall remain in force, the provision of 
this Agreement shall control and such provision of such other 
agreement shall be deemed to have been superseded, and to be of no 
force or effect, as if such other agreement had been formally 
amended to the extent necessary to accomplish such purpose.

7.   Validity.  The invalidity or unenforceability of any 
provision of this Agreement shall not affect the validity or 
enforceability of any other provision of this Agreement, which 
shall remain in full force and effect.

8.   Counterparts.  This Agreement may be executed in several 
counterparts, each of which shall be deemed to be an original but 
all of which together will constitute one and the same instrument.

9.   Notice.  Any purported termination by the Corporation or by 
you following a Change in Control shall be communicated to the 
other party by a Notice of Termination. A Notice of Termination 
shall indicate the specific termination provision in this 
Agreement relied upon and shall set forth in reasonable detail the 
facts and circumstances claimed to provide a basis for termination 
of your employment under the provision so indicated. For the 
purpose of this Agreement, notices and all other communications 
provided for in the Agreement shall be in writing and shall be 
deemed to have been duly given when delivered or mailed by United 
States registered mail, return receipt requested, postage prepaid, 
addressed to the respective addresses set forth on the first page 
of this Agreement, provided that all notices to the Corporation 
shall be directed to the attention of the Board with a copy to the 
Secretary of the Corporation, or to such other address as either 
party may have furnished to the other in writing in accordance 
herewith, except that notice of change of address shall be 
effective only upon receipt.

10.  Fees and Expenses.  The Corporation shall pay all legal fees 
and related expenses incurred by you as a result of your 
termination following a Change in Control or by you in seeking to 
obtain or enforce any right or benefit provided by this Agreement 
(including all fees and expenses, if any, incurred in contesting 
or disputing any such termination or incurred by you in seeking 
advice in connection therewith).

11.  Survival.  The respective obligations of, and benefits 
afforded to, the Corporation and you as provided in Paragraphs 3, 
5, 6 and 10 of this Agreement shall survive termination of this 
Agreement.

12.  Miscellaneous.  No provision of this Agreement may be 
modified, waived or discharged unless such waiver, modification or 
discharge is agreed to in writing and signed by you and such 
officer as may be specifically designated by the Board. No waiver 
by either party hereto at any time of any breach by the other 
party hereto of, or compliance with, any condition or provision of 
this Agreement to be performed by such other party shall be deemed 
a waiver of similar or dissimilar provisions or conditions at the 
same or at any prior or subsequent time. No agreements or 
representations, oral or otherwise, express or implied, with 
respect to the subject matter hereof have been made by either 
party which are not expressly set forth in this Agreement. The 
validity, interpretation, construction and performance of this 
Agreement shall be governed by the laws of the State of New York.

     If this letter sets forth our agreement on the subject matter 
hereof, kindly sign and return to the Corporation the enclosed 
copy of this letter which will then constitute our agreement on 
this subject.

                                    Sincerely,

                                    UNION CARBIDE CORPORATION



                                    Robert D. Kennedy 
                                    Chairman of the Board and
                                    Chief Executive Officer


Agreed to this 12th day
of August, 1992
