Dear Ron:
     At its meeting on January 27, 1998, the Board of Directors 
(the "Board") of Union Carbide Corporation (the "Corporation") 
authorized your participation in the arrangements set forth in 
this Severance Compensation Agreement.
     The Board 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 continued service to the 
Corporation, the Corporation agrees that you shall receive the 
severance benefits set forth in this Severance Compensation 
Agreement ("Agreement") in the event your employment with the 
Corporation is terminated subsequent to a Change in Control of 
the Corporation 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) any "person" or "group" within 
the meaning of Sections 13(d) and 
14(d)(2) of the Securities Exchange 
Act of 1934 ("Act") 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;
(ii) any "person" or "group" within 
the meaning of Sections 13(d) and 
14(d)(2) of the Act 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 with respect to 
more than 20% of the then 
outstanding voting securities of 
the Corporation;
(iii) if during any period of 
twenty-four consecutive months, 
Present Directors and/or New 
Directors cease for any reason to 
constitute a majority of the Board.
For these purposes, "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;
(iv) the stockholders of the 
Corporation approve a plan of 
complete liquidation or dissolution 
of the Corporation; or
(v) there shall be consummated (x) 
a reorganization, merger or 
consolidation of all or 
substantially all of the assets  of 
the Corporation (a "Business 
Combination"), unless, following 
such Business Combination, (a) all 
or substantially all of the 
individuals and entities who were 
the beneficial owners, 
respectively, of the outstanding 
Common Stock of the Corporation and 
outstanding voting securities of 
the Corporation immediately prior 
to such Business Combination 
beneficially own, directly or 
indirectly, more than 50% of, 
respectively, the then outstanding 
shares of common stock and the 
combined voting power of the then 
outstanding voting securities 
entitled to vote generally in the 
election of directors, as the case 
may be, of the corporation 
resulting from such Business 
Combination (including, without 
limitation, a corporation which as 
a result of such transaction owns 
the Corporation or all or 
substantially all of the 
Corporation's assets either 
directly or through one or more 
subsidiaries) in substantially the 
same proportions as their 
ownership, immediately prior to 
such Business Combination of the 
outstanding Common Stock of the 
Corporation and outstanding voting 
securities of the Corporation, as 
the case may be, (b) no Person 
(excluding any corporation 
resulting from such Business 
Combination or any employee benefit 
plan (or related trust) of the 
Corporation or such corporation 
resulting from such Business 
Combination) beneficially owns, 
directly or indirectly, 20% or more 
of, respectively, the then 
outstanding shares of common  stock 
of the corporation resulting from 
such Business Combination or the 
combined voting power of the then 
outstanding voting securities of 
such corporation except to the 
extent that such ownership existed 
prior to the Business Combination, 
and (c) at least a majority of the 
members of the board of directors 
of the corporation resulting from 
such Business Combination were 
members of the Board at the time of 
the execution of the initial 
agreement, or of the action of the 
Board, providing for such Business 
Combination; 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 of 
the Corporation.

     Notwithstanding the foregoing, a Change in Control of the 
Corporation shall not be deemed to occur: (A) pursuant to 
Subparagraphs (i) and (ii) above, solely because twenty percent 
(20%) or more of the combined voting power of the Corporation's 
then outstanding securities is acquired by one or more employee 
benefit plans maintained by the Corporation; or (B) pursuant to

as amended.

Termination is given (provided that 
you shall not have returned to the 
full-time performance of your

period), and
(ii) in all other cases, the date 
specified in the Notice of

the date such Notice of Termination 
is given).
     d.     "Disability" shall mean total physical or mental 
disability rendering you unable to perform the duties of your 
employment for a continuous period of six (6) months. Any 
question as to the existence of your 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.
     e.     "Good Reason for Resignation" shall mean, without 
your express written consent, any of the following:

your reporting responsibility as it 
existed immediately prior to a

for all employees of the

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 a 
Change in Control of the 
Corporation;
(v) the failure by the Corporation

Resignation with Good Reason for Resignation.  If your employment

Control of the Corporation and during the term of this Agreement 
(a) by the Corporation other than for Retirement, Death, 
Disability or Termination for Cause, 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, not 
later than the fifth day following 
the Date of Termination, your base 
salary and vacation pay accrued 
through the Date of Termination 
(including any banked vacation, 
vested vacation for the calendar 
year in which the Date of 
Termination occurs and pro-rated, 
vested vacation for the calendar 
year following the year in which 
the Date of Termination occurs) 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 of the 
Corporation, if such rate was 
higher).
(ii) Accrued Incentive 
Compensation.  The Corporation 
shall pay you, not later than 
thirty (30) days following your 
Date of Termination, the amount of 
your accrued Incentive Compensation 
which shall be the sum of the 
amounts set forth in the following 
paragraphs (A) and (B).
(A) If the Date of Termination is 
after the end of a Variable 
Compensation Year, but before 
Incentive Compensation for said 
Variable Compensation Year has been 
paid, the Corporation shall pay to 
you under this Agreement for your 
service during such Variable 
Compensation Year the greatest of 
the amounts set forth in the 
following paragraphs (I), (II), 
(III) and (IV):
(I) an amount that bears the same 
ratio to your base salary in said 
Variable Compensation Year as the 
Incentive Compensation paid to you 
with respect to the immediately 
prior Variable Compensation Year 
bears to your base salary for said 
prior Variable Compensation Year;
(II) an amount that bears the same 
ratio to your base salary for such 
Variable Compensation Year as the 
average Incentive Compensation paid 
to you during the three (3) 
immediately prior Variable 
Compensation Years bears to your 
average base salary for said three 
(3) prior years;
(III) the amount of your target 
variable compensation payment 
(i.e., the percent of your salary 
grade midpoint at risk) for such 
Variable Compensation Year; or
(IV)  the  average amount of  
Incentive Compensation, as a 
percentage of base salary, paid to 
other executives of the Corporation 
at the same (or equivalent) grade 
level as yourself.
(B) In addition, if the Date of 
Termination is other than the first 
day of a Variable Compensation 
Year, the Corporation shall pay to 
you under this Agreement for your 
service during such Variable 
Compensation Year up to the Date of 
Termination, the greatest of the 
amounts set forth in the following 
paragraphs (I), (II) and (III):
(I) an amount that bears the same 
ratio to your base salary (earned 
up to the Date of Termination) in 
said Variable Compensation Year as 
the Incentive Compensation paid to 
you with respect to the immediately 
prior Variable Compensation Year 
under the Incentive Compensation 
Plan or pursuant to clause (A) 
above bears to your base salary for 
said prior Variable Compensation 
Year;
(II) an amount that bears the same 
ratio to your base salary earned 
(up to the Date of Termination) for 
such Variable Compensation Year as 
the average Incentive Compensation 
paid to you with respect to the 
three (3) Variable Compensation 
Years immediately prior to such 
Variable Compensation Year under 
the Incentive Compensation Plan or 
pursuant to clause (A) above bears 
to your average base salary for 
said three (3) prior years; or
(III) the amount of your target 
variable compensation payment 
(i.e., the percent of your salary 
grade midpoint at risk) for such 
Variable Compensation Year 
multiplied by a fraction, the 
numerator of which is the total 
number of days which have elapsed 
in the current Variable 
Compensation Year to the Date of 
Termination, and the denominator of 
which is three hundred sixty-five 
(365).
If there is more than one Incentive 
Compensation Plan, your accrued 
Incentive Compensation under each 
Incentive Compensation Plan shall 
be determined separately for each 
such Plan.
For the purpose of determining the 
amount of your accrued Incentive 
Compensation under this Paragraph 
2a(ii), you will be deemed to have 
been paid the full amount of all 
prior Incentive Compensation, 
whether or not such Incentive 
Compensation was includible in your 
gross income for Federal income tax 
purposes.
(iii) Insurance Coverage.  The 
Corporation shall arrange to 
provide you (and your dependents, 
if applicable) with life, 
disability, accident, dental and 
medical benefits substantially 
equivalent to those which you are 
receiving, or were entitled to 
receive, from the Corporation or a 
subsidiary of the Corporation 
immediately prior to a Change in 
Control of the Corporation. Such 
benefits shall be provided to you 
for the longer of (x) thirty-six 
(36) months after such Date of 
Termination or (y) the period 
during which such benefits would 
have been provided to you, as a 
terminated employee, under the 
applicable life, disability, 
accident, dental and medical plans 
in effect immediately prior to a 
Change in Control of the 
Corporation (except that after a 
period of thirty-six (36) months 
such benefits shall be provided to 
you on the same financial terms and 
conditions as provided for under 
the respective plans).
If you are a participant in the 
Corporation's Executive Life 
Insurance Plan, you shall have the 
same rights thereunder as a person 
who retires with a non-actuarially 
reduced pension (whether or not you 
are eligible for such a pension).
Should it be determined that any of 
the medical benefits to be provided 
to you (and your dependents, if 
applicable) under this subparagraph 
(iii) could be included in your 
gross income for federal, state or 
local tax purposes, then the 
following shall apply:
(A) If you have a right to receive 
an immediate pension on your Date 
of Termination, then you shall 
participate in the Corporation's 
medical benefit plans as if you 
retired from the Corporation on 
your Date of Termination, except 
that the Corporation shall provide 
such medical coverage at no cost to 
you for three (3) years following 
your Date of Termination and
thereafter, you shall participate 
therein on the same terms as other 
retired employees;
(B) If you do not have a right to 
receive an immediate pension on 
your Date of Termination, you will 
no longer continue to participate 
in the Corporation's medical 
benefit plans and (i) the 
Corporation shall provide you with 
a cash payment in an amount equal 
to the amount required by you to 
pay for coverage under COBRA for 
the first eighteen (18) months 
following your loss of medical 
coverage, and thereafter, (ii) the 
Corporation shall, for the 
subsequent eighteen (18) months, 
purchase for you at its cost, a 
policy of medical insurance 
providing benefits substantially 
similar to the benefits you would 
have received under the 
Corporation's medical benefit 
plans.
(iv) Retirement Benefits.  The 
Corporation shall pay you, as 
hereafter provided in this 
subparagraph (iv), at the time you 
are entitled to be paid a 
retirement pension under the 
Retirement Program, a retirement 
pension equal to the greater of:
(A) an amount computed in 
accordance with the terms of the 
Retirement Program in effect 
immediately prior to a Change in 
Control of the Corporation and as 
if those terms were in effect on 
the Date of Termination, or
(B) an amount computed in 
accordance with the terms of the 
Retirement Program in effect on the 
Date of Termination;
in either case less the amount of 
retirement pension actually to be 
paid to you under the Retirement 
Program in the absence of this 
subparagraph (iv).
In computing the amounts of your 
retirement pension under clauses 
(A) and (B) above, three years 
shall be added to your actual age 
and to your actual Company Service 
Credit under the Retirement Program 
so that your retirement pension 
under clauses (A) and (B) above 
will be the amount it would have 
been if you had been three years 
older than you actually were, and 
you had three years more Company 
Service Credit than you actually 
had, on the Date of Termination.
If for any reason, the benefits 
under this subparagraph (iv) cannot 
be paid under the tax-qualified 
portion of the Retirement Program, 
the Corporation shall, at its 
option, provide such benefits to 
you through the purchase, and 
delivery to you, of a non-qualified 
annuity from an insurance company, 
or pay you a lump sum payment for 
the benefits under this 
subparagraph (iv) calculated under 
such one of the following options 
as would produce the highest lump 
sum payment:
(I) calculated under the same 
factors (interest rate and 
mortality) as lump sum payments are 
made under the Corporation's 
Supplemental Retirement Income Plan 
and Equalization Benefit Plan as in 
effect immediately prior to a 
Change in Control of the 
Corporation;
(II) calculated under the same 
factors (interest rate and 
mortality) as lump sum payments are 
made under the Corporation's 
Supplemental Retirement Income Plan 
and Equalization Benefit Plan, or 
other similar plans, as in effect 
on the Date of Termination; or
(III) calculated under the same 
factors (interest rate and 
mortality) as lump sum payments 
would have been calculated under 
the Corporation's Supplemental 
Retirement Income Plan and 
Equalization Benefit Plan on the 
Date of Termination, if such 
factors were determined using the 
same methodology as such plans used 
prior to a Change in Control of the 
Corporation.
(v) Outplacement Counseling.  The 
Corporation shall make available to 
you, at the Corporation's expense, 
outplacement counseling for a 
period of up to one year.  You may 
select the organization that will 
provide the outplacement 
counseling, however, the 
Corporation's obligation to provide 
you benefits under this 
subparagraph (v) shall be limited 
to $35,000.
(vi) Financial Counseling.  The 
Corporation shall, within 60 days 
of the Date of Termination, make 
available to you financial 
counseling, tax counseling and tax 
preparation services.  You may 
select the organization that will 
provide such services.  However, 
the Corporation's obligation to 
provide you benefits under this 
subparagraph (vi) shall be limited 
to $10,000.  The Corporation shall 
provide to you any information you 
request regarding your personal and 
financial situation that you wish 
to provide to the financial 
counseling firm in order for the 
firm to provide the counseling 
services required by this 
subparagraph (vi).
(vii) Severance Payment.  The 
Corporation shall pay as a 
severance payment to you, not later 
than the fifth day following the 
Date of Termination, a lump sum 
severance payment (the "Severance 
Payment") equal to three (3) times 
the sum of the amounts set forth in 
the following paragraphs (A), (B), 
(C), (D) and (E):
(A) the greater of your annual base 
salary which was payable to you by 
the Corporation immediately prior 
to the Date of Termination or your 
annual base salary which was 
payable to you by the Corporation 
immediately prior to a Change in 
Control of the Corporation; plus
(B) the greater of:
(I) the amount of your most recent 
Profit Sharing Award received prior 
to the Date of Termination; or
(II) the amount of your most recent 
Profit Sharing Award received prior 
to a Change in Control of the 
Corporation; or
(III) an amount that bears the same 
ratio to your annual base salary in 
effect immediately prior to the 
Date of Termination, or, if higher, 
your annual base salary in effect 
immediately prior to a Change in 
Control of the Corporation, as the 
average Profit Sharing Award paid 
or payable to you during the three 
(3) immediately full calendar years 
prior to the Date of Termination 
bears to your average base salary 
for said three (3) prior years; 
plus
(C) the greater of:
(I) the amount of your most recent 
Incentive Compensation Award 
received prior to the Date of 
Termination; or
(II) the amount of your most recent 
Incentive Compensation Award 
received prior to a Change in 
Control of the Corporation; or
(III) an amount that bears the same 
ratio to your annual base salary in 
effect immediately prior to the 
Date of Termination, or, if higher, 
your annual base salary in effect 
immediately prior to a Change in 
Control of the Corporation, as the 
average Incentive Compensation 
Award paid to you with respect to 
the three (3) immediately prior 
Incentive Compensation Years bears 
to your average base salary for 
said three (3) prior years; plus
(D) the greater of:
(I) the value, as determined by the 
Corporation at the time of the 
grant, attributable to any stock 
options awarded to you by the 
Corporation at the most recent date 
of grant of stock options prior to 
the Date of Termination; or

the Corporation at the time of 
grant, attributable to any stock 
options awarded to you by the

Corporation.
In determining such value, the 
number of stock options awarded to 
you shall be multiplied by the 
value ascribed to a stock option by 
the Corporation using the Black-
Scholes method or other similar 
methodology.  If at the time of 
either of such grants it is 
specified in writing that the grant 
covers a period of more than one 
year, then the value of such grant 
as determined above shall be 
annualized by dividing such value 
by the number of years (or part 
thereof) the grant is specified to 
cover; plus
(E) the greater of:
(I) the value, as determined by the 
Corporation at the time of the 
grant, attributable to the grant to 
you by the Corporation of 
performance or restricted stock of 
the Corporation at the most recent 
date of grant prior to the Date of 
Termination; or
(II) the value, as determined by 
the Corporation at the time of 
grant, attributable to the grant to 
you by the Corporation of 
performance or restricted stock of 
the Corporation at the most recent 
date of grant prior to a Change in 
Control of the Corporation.
If at the time of either of such 
grants it is specified in writing 
that the grant covers a period of 
more than one year, then the value 
of such grant as determined above 
shall be annualized by dividing 
such value by the number of years 
(or part thereof) the grant is 
specified to cover.  In determining 
such annualized value, the number 
of shares of performance or 
restricted stock awarded to you 
shall be multiplied by the closing 
price of the common stock of the 
Corporation on the New York Stock 
Exchange-Composite Transactions on 
the date of grant.
For purposes of calculations under 
this subparagraph (vii), the 
amounts of base salary, Profit 
Sharing Awards and Incentive 
Compensation Awards shall be the 
amounts calculated without regard 
to whether or not such amounts were 
includible in your gross income for 
Federal income tax purposes.
The Severance Payment shall not be 
reduced to the extent the 
Corporation could not properly 
deduct amounts paid pursuant to 
Paragraph 2a(i) through 2a(vii) 
hereof or otherwise pursuant to 
Section 280G of the Code.
(viii) Reduction in Severance 
Payment.  The Severance Payment 
shall be reduced only in the event 
specified in this subparagraph 
(viii).  If the aggregate present 
value, as determined for purposes 
of Code Section 280G, of all 
amounts that are parachute payments 
for purposes of such Section 
exceeds the limitation set forth in 
Code Section 280G(b)(2)(A)(ii) by 
an amount not exceeding $50,000, 
then there shall be a reduction in 
the amount of your Severance 
Payment so that such limit is not 
exceeded.
(ix) Payment of Taxes.
(A) For purposes of this 
subparagraph (ix), the following 
terms  shall  have the  following 
meanings:
(I) Payment shall mean any payment 
or distribution (or acceleration of 
benefits) by the Corporation to or 
for your benefit (whether paid or 
payable or distributed or 
distributable (or accelerated) 
pursuant to the terms of this 
Agreement or otherwise, but 
determined without regard to any 
additional payments required under 
this subparagraph (ix)). In 
addition, Payment shall also 
include the amount of income deemed 
to be received by you as a result 
of the acceleration of the 
exercisability of any of your 
options to purchase stock of the 
Corporation, the acceleration of 
the lapse of any restrictions on 
performance stock or restricted 
stock of the Corporation held by 
you or the acceleration of payment 
from any deferral plan.
(II) Excise Tax shall mean the 
excise tax imposed by Section 4999 
of the Code, or any interest or 
penalties incurred by you with 
respect to such excise tax.
(III) Income Tax shall mean all 
taxes other than the Excise Tax 
(including any interest or 
penalties imposed with respect to 
such taxes) including, without 
limitation, any income and 
employment taxes imposed by any 
federal (including (i) FICA and 
Medicare taxes, and (ii) the tax 
resulting from the loss of any 
federal deductions or exemptions 
which would have been available to 
you but for receipt of the Payment), 
state, local, commonwealth or 
foreign government.
(B) In the event it shall be 
determined that a Payment would be 
subject to an Excise Tax, then you 
shall be entitled to receive an 
additional payment (a "Gross-Up 
Payment") in an amount such that 
after payment by you of Income Tax 
and Excise Tax imposed upon the 
Gross-Up Payment, you retain an 
amount of the Gross-Up Payment 
equal to the Excise Tax imposed 
upon the Payment.
(C) All determinations required to 
be made under this subparagraph 
(ix), including whether and when a 
Gross-Up Payment is required and 
the amount of such Gross-Up Payment 
and the assumptions to be utilized 
in arriving at such determination, 
shall be made by the public 
accounting firm that is retained by 
the Corporation as of the date 
immediately prior to a Change in 
Control of the Corporation (the 
"Accounting Firm") which shall 
provide detailed supporting 
calculations both to the 
Corporation and to you within 
fifteen (15) business days of the 
receipt of notice from you that 
there has been a Payment, or such 
earlier time as is requested by the 
Corporation (collectively, the 
"Determination").  In the event 
that the Accounting Firm is serving 
as accountant or auditor for the 
individual, entity or group 
effecting a Change in Control of 
the Corporation, you may appoint 
another nationally recognized 
public accounting firm to make the 
determinations required hereunder 
(which accounting firm shall then 
be referred to as the Accounting 
Firm hereunder).  All fees and 
expenses of the Accounting Firm 
shall be borne solely by the 
Corporation.  Any Gross-Up Payment, 
as determined pursuant to this 
subparagraph (ix), shall be paid by 
the Corporation to you within ten 
(10) days of the Determination.  If 
the Accounting Firm determines that 
no Excise Tax is payable by you, 
you may request the Accounting Firm 
to furnish you with a written 
opinion that failure to report the 
Excise Tax on your applicable 
federal income tax return would not 
result in the imposition of a 
negligence or similar penalty.  The 
Determination by the Accounting 
Firm shall be binding upon the 
Corporation and you.  As a result 
of the uncertainty in the 
application of Section 4999 of the 
Code at the time of the 
Determination, it is possible that 
Gross-Up Payments which will not 
have been made by the Corporation 
should have been made 
("Underpayment"), consistent with 
the calculations required to be 
made hereunder.  In the event that 
the Corporation exhausts its 
remedies pursuant to subparagraph 
(ix)(D) below and you thereafter 
are required to make payment of any 
Excise Tax or income Tax, the 
Accounting Firm shall determine the 
amount of the Underpayment that has 
occurred and any such Underpayment 
shall be promptly paid by the 
Corporation to or for your benefit.
(D) You shall notify the 
Corporation in writing of any claim 
by the Internal Revenue Service 
that, if successful, would require 
the payment by the Corporation of 
the Gross-Up Payment or the 
Underpayment.  Such notification 
shall be given as soon as 
practicable but no later than ten 
(10) business days after you are 
informed in writing of such claim 
and shall apprise the Corporation 
of the nature of such claim and the 
date on which such claim is 
requested to be paid.  You shall 
not pay such claim prior to the 
expiration of the 30-day period 
following the date on which you 
give such notice to the Corporation 
(or such shorter period ending on 
the date that any payment of taxes 
with respect to such claim is due).  
If the Corporation notifies you in 
writing prior to the expiration of 
such period that it desires to 
contest such claim, you shall:
(1) give the Corporation any 
information reasonably requested by 
the Corporation relating to such 
claim,
(2) take such action in connection 
with contesting such claim as the 
Corporation shall reasonably 
request in writing from time to 
time, including, without 
limitation, accepting legal 
representation with respect to such 
claim by an attorney reasonably 
selected by the Corporation,
(3) cooperate with the Corporation 
in good faith in order effectively 
to contest such claim, and
(4) permit the Corporation to 
participate in any proceeding 
relating to such claim;
provided, however, that the 
Corporation shall bear and pay 
directly all costs and expenses 
(including additional interest and 
penalties) incurred in connection 
with such contest and shall 
indemnify and hold you harmless, on 
an after-tax basis, for any Excise 
Tax or Income Tax imposed as a 
result of such representation and 
payment of costs and expenses.  
Without limitation on the foregoing 
provisions of this subparagraph 
(ix)(D), the Corporation shall 
control all proceedings taken in 
connection with such contest and, 
at its sole option, may pursue or 
forego any and all administrative 
appeals, proceedings, hearings and 
conferences with the taxing 
authority in respect of such claim 
and may, at its sole option, either 
direct you to pay the tax claimed 
and sue for a refund or contest the 
claim in any permissible manner, 
and you agree to prosecute such 
contest to a determination before 
any administrative tribunal, in a 
court of initial jurisdiction and 
in one or more appellate courts, as 
the Corporation shall determine; 
provided further, that if the 
Corporation directs you to pay such 
claim and sue for a refund, the 
Corporation shall advance the 
amount of such payment to you on an 
interest-free basis and shall 
indemnify and hold you harmless, on 
an after-tax basis, from any Excise 
Tax or Income Tax imposed with 
respect to such advance or with 
respect to any imputed income with 
respect to such advance; and 
provided further, that any 
extension of the statute of 
limitations relating to payment of 
taxes for your taxable year with 
respect to which such contested 
amount is claimed to be due is 
limited solely to such contested 
amount.  Furthermore,  the 
Corporation's control of the 
contest shall be limited to issues 
with respect to which a Gross-Up 
Payment would be payable hereunder 
and you shall be entitled to settle 
or contest, as the case may be, any 
other issue raised by the Internal 
Revenue Service or any other taxing 
authority.
(E) If, after the receipt by you of 
an amount advanced by the 
Corporation pursuant to 
subparagraph (ix)(D) above, you 
become entitled to receive, and 
receive, any refund with respect to 
such claim, you shall (subject to 
the Corporation's complying with 
the requirements of subparagraph 
(ix)(D)) promptly pay to the 
Corporation the amount of such 
refund (together with any interest 
paid or credited thereon after 
taxes applicable thereto).  If, 
after the receipt by you of an 
amount advanced by the Corporation 
pursuant to subparagraph (ix)(D), a 
determination is made that you 
shall not be entitled to any refund 
with respect to such claims and the 
Corporation does not notify you in 
writing of its intent to contest 
such denial of refund prior to the 
expiration of thirty (30) days 
after such determination, then such 
advance shall be forgiven and shall 
not be required to be repaid.
(x) No Duty to Mitigate.  You shall 
not be required to mitigate the 
amount of any payment provided for 
in this Paragraph 2 by seeking 
other employment or otherwise, nor 
shall the amount of any payment or 
benefit hereunder 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; provided, however, 
should you become reemployed in a 
job which (a) offers medical plan 
benefits which are equal to or 
greater than the medical plan 
benefits provided to you under 
subparagraph 2(a)(iii), and (b) 
such medical plan benefits are 
offered to you at no cost, you 
shall no longer be eligible to 
receive medical plan benefits under 
this Agreement.
     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 Disability or as a 
result of a physical or mental disability that is not total and 
therefore is not a 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 or provided under the Corporation's benefit plans, 
including its disability plans.  After the Date of Termination 
for Disability, your benefits shall be determined in accordance 
with the Retirement Program, insurance and other applicable 
programs of the Corporation.  The compensation and benefits, 
other than salary, payable or provided pursuant to this 
subparagraph b 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 Termination by 
You Other Than With Good Reason for Resignation.  If your 
employment shall be terminated by the Corporation as a 
Termination for Cause or by you other than with Good Reason for 
Resignation, the Corporation shall pay you your full base salary 
and accrued vacation pay (including any banked vacation, vested 
vacation for the calendar year in which the Date of Termination 
occurs, and prorated, vested vacation for the calendar year 
following the year in which the Date of Termination occurs) 
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.  You shall receive any payment due under this 
subparagraph c on your Date of Termination.  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.
3.     Term of Agreement.  This Agreement shall commence on the 
date hereof and shall continue in effect through December 31 
1998; provided, however, that commencing on January 1, 1999 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 does not wish to 
extend this Agreement.  Notwithstanding any such notice by the 
Corporation not to extend, if a Change in Control of the 
Corporation shall have occurred during the original or any 
extended term of this Agreement, or within three months 
thereafter, this Agreement shall continue in effect.  In any 
event, the term of this Agreement shall expire on the third (3rd) 
anniversary of the date of a Change in Control of the 
Corporation.  This Agreement shall terminate if your employment 
is terminated by you or the Corporation prior to a Change in 
Control of the Corporation.
4.     Successors; Binding Agreement.
     a.     Successors of the Corporation.  The Corporation will 
require any Successor to expressly assume and agree 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 2a hereof upon delivery by you of a Notice of 
Termination.  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(i) or (ii).

     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 following 
your Date of Termination 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.
5.     Nature of Payments.  All payments to you under this 
Agreement shall be considered either payments in consideration of 
your continued service to the Corporation or severance payments 
in consideration of your past service to the Corporation.
6.     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.
7.     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.
8.     Notice.  Any purported termination of your employment by 
the Corporation or by you following a Change in Control of the 
Corporation shall be communicated to the other party by a written 
Notice of Termination.  A Notice of Termination by you shall 
indicate in reasonable detail the facts and circumstances claimed 
to provide a basis for a Good Reason for Resignation.  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.

9.     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 of the Corporation 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).
10.     Miscellaneous.  No provision of this Agreement may be 
amended,  modified,  waived  or  discharged unless  such  
amendment, modification, waiver 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.
11.     Governing Law.  The validity, interpretation, 
construction and performance of this Agreement shall be governed 
by the laws of the State of New York (without regard to the 
choice of laws provisions thereof).
     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.
