     3.3     The Committee's decisions, actions and interpretations

as the Committee shall determine.



Section 5:          Pay-At-Risk
     5.1     Overview:  The Corporation will reduce each Participant's 
Variable Compensation by the amount of the Pay-At-Risk, as provided in 
Sections 5.2 and 5.3.  The Pay-At-Risk will be converted to Pay-At-Risk 
Shares as provided in Section 5.4.  If the 1999 and 2000 performance 
goals established pursuant to this Plan are not met, the Pay-At-Risk 
Shares will be forfeited.  If the goals are met, a Participant will 
receive the value of the Pay-At-Risk Shares and the Award Shares as 
provided in Sections 6 and 7.
     5.2     Determination of Pay-at-Risk:  The Pay-At-Risk for each 
Participant will equal a percentage of such Participant's annual base 
salary, in effect as of September 30, 1997, as follows:

               CEO                                     =    100%
               Corporate Vice Presidents and 
               Vice President/General Managers         =    65%
               Other Selected Participants             =    40%

     5.3     Reduction of Variable Compensation: Variable Compensation, 
if any, which would otherwise be paid to the Participant in each of the 
three years, 1998, 1999 and 2000 will be reduced by one-third of the 
Pay-At-Risk.  The reduction shall be made after the Variable 
Compensation is determined in accordance with the terms of the plans 
under which the Variable Compensation is paid and before any deduction 
for deferral of Variable Compensation pursuant to the Compensation 
Deferral Plan.  If for any reason, the Variable Compensation in any year 
is less than the required reduction, any deficit would be carried over 
and a subsequent year's Variable Compensation shall be reduced as 
approved by the CEO.  Based on individual circumstances, the CEO may 
allow Participants, other than the CEO, to have the Participant's 
Variable Compensation reduced over a period longer than three years.  
Upon the request of a Participant, the CEO may allow Participants 
(including himself) to elect to have the Participant's Variable 
Compensation reduced over a period shorter than three years.
     5.4     Phantom Shares:  The Pay-At-Risk will be converted to the 
number of Phantom Shares determined by dividing the Pay-At-Risk by the 
Closing Price on September 24, 1997, which price was $47.75 (the "Pay-
At-Risk Shares").  In the event such conversion results in a fractional 
Pay-At-Risk Share, the Pay-At-Risk Shares shall be rounded to the next 
highest whole number.
     5.5     Dividends:  The Pay-At-Risk Shares, the Reduced Pay-At-Risk 
Shares and any Dividend Shares thereon will be credited with amounts 
equal to dividends paid on the Corporation's common stock and deemed 
reinvested in additional Phantom Shares (or fractions thereof) based 
upon the Closing Price on the date such dividends are paid by the 
Corporation.  Whenever the Pay-At-Risk Shares or the Reduced Pay-At-Risk 
Shares are forfeited under the terms of the Plan, the Dividend Shares 
thereon shall also be forfeited.  Whenever the value of the Pay-At-Risk 
Shares or Reduced Pay-At-Risk Shares is to be paid to a Participant 
under the terms of the Plan, the value of the Dividend Shares thereon 
shall also be paid to the Participant.

Performance Period are based on EPS and Recalculated EPS as set forth in

EPS.

     7.1     Pay-At-Risk Shares:  If a Participant does not forfeit the 
Pay-At-Risk Shares or the Reduced Pay-At-Risk Shares pursuant to Section 
6.4 or Section 8, then the value of the Pay-At-Risk Shares or the

     7.2     Awards:  The value of one-third of the Award Shares shall

Pay-At-Risk Shares and the Award Shares to be paid to the Participant 
pursuant to Sections 7.1 and 7.2 shall be determined by using the 
average of the Closing Prices on each trading day in January of the year 
of payment.
     7.4     Deferral:  Participants can elect to defer any or all of 
the payments under Sections 7.1 and 7.2 in accordance with the terms of 
the Compensation Deferral Plan.

receive the value of the Pay-At-Risk Shares, the Reduced Pay-At-Risk 
Shares or Award Shares, and is employed by the Corporation on January 
31, 2002 but does not meet by January 31, 2002 the stock ownership 
guidelines as heretofore or hereafter established by the Corporation, 
the Participant shall forfeit on such date 50% of each of (i) the Pay-
At-Risk Shares or Reduced Pay-At-Risk Shares, (ii)  the Award Shares and

Variable Compensation is reduced for Pay-At-Risk will continue to be 
counted as part of the Participant's pensionable earnings under the

the terms of the Retirement Program.  Any payment of the Pay-At-Risk 
Shares, Reduced Pay-At-Risk Shares or Award Shares under Section 7.1 and 
7.2 of this Plan will not be considered pensionable earnings under the 
Corporation's Retirement Program or for any other benefit plan purpose.
     7.7     Dividends:  The Award Shares and any Dividend Shares 
thereon will be credited with amounts equal to dividends paid on the 
Corporation's common stock and deemed reinvested in additional Phantom 
Shares (or fractions thereof) based upon the Closing Price on the date 
such dividends are paid by the Corporation.  Whenever the Award Shares 
are forfeited under the terms of the Plan, the dividends thereon shall 
also be forfeited.  Whenever the value of the Award Shares is to be paid 
to a Participant under the terms of the Plan, the value of the Dividend 
Shares thereon shall also be paid to the Participant.
     7.8     Corporate Changes:  In the event of any change in the 
number of outstanding shares of common stock of the Corporation by 
reason of any stock split, stock dividend, recapitalization, merger, 
consolidation, combination or exchange of shares or other similar 
corporate change or in the event of any special distribution to the 
stockholders, the Committee shall make such equitable adjustments in the 
number of Pay-At-Risk Shares, Reduced Pay-At-Risk Shares and Award 
Shares, both under the Plan as a whole and with respect to individuals, 
as the Committee determines are necessary and appropriate.  Any such 
adjustment shall be final and binding upon all Participants, 
Beneficiaries, shareholders of the Corporation and any other person.

Section 8:          Termination of Employment
     8.1     If a Participant terminates employment before 2001, no 
Award shall be paid and the Pay-At-Risk Shares shall be forfeited except 
as set forth in Sections 8.2 and 8.3, unless the Committee determines it 
is in the best interests of the Corporation to permit individual 
exceptions.  
     8.2     In the case of a Participant's death, disability or 
termination of employment by the Corporation other than for cause prior 
to 1999, the Participant shall not be entitled to any Award Shares and 
the then value of the portion of Pay-At-Risk Shares which represents the 
Pay-At-Risk for which the Participant's Variable Compensation has 
actually been reduced, shall be paid to the Participant within sixty 
days after the date of such death, disability or termination of 
employment.  Such value shall be determined using the average Closing 
Price on the first ten days of trading following the date of such death, 
disability or termination of employment.
     In the case of a Participant's Retirement prior to 1999, the 
Participant shall not be entitled to any Award Shares and the value of 
the portion of the Pay-At-Risk Shares which represents Pay-At-Risk for 
which the Participant's Variable Compensation has actually been reduced, 
shall be paid to the Participant as provided in Section 7.1.  Such value 
shall be determined pursuant to Section 7.3.
     8.3     In the case of a Participant's death, disability, 
Retirement or termination of employment by the Corporation other than 
for cause during 1999 or 2000, the Pay-At-Risk Shares shall be reduced 
to equal the Pay-At-Risk Shares multiplied by a fraction, the numerator 
of which is the number of days from January 1, 1999 to, and including, 
the date of death, disability, Retirement or such termination of 
employment, and the denominator of which is 731, and further reduced, if 
necessary, to represent only Pay-At-Risk for which the Participant's 
Variable Compensation has actually been reduced ("Reduced Pay-At-Risk 
Shares").  A grant of Award Shares, if any, to any such Participant 
shall be based only upon the Reduced Pay-At-Risk Shares.  The value of 
the excess of the Pay-At-Risk Shares less the Reduced Pay-At-Risk Shares 
(plus dividends on such excess), to the extent such excess represents 
Pay-At-Risk for which the Participant's Variable Compensation has 
actually been reduced, shall be paid to the Participant as follows:  (i) 
in the case of the Participant's death, disability or termination of 
employment by the Corporation other than for cause, within sixty days 
after the date of such death, disability or termination of employment; 
and (ii) in the case of Retirement at the time provided for in Section 
7.1.  For the events described in clause (i) above, such value shall be 
determined using the average Closing Price on the first ten days of 
trading following the date of such death, disability or termination of 
employment.  For the event described in clause (ii) above, such value 
shall be determined pursuant to Section 7.3.  The value of the reduced 
Pay-At-Risk Shares and the Award Shares, if any, shall be paid to the 
Participant as provided in Section 7.1 and 7.2 and such value shall be 
determined as provided in Section 7.3.
     8.4     If a Participant terminates employment for any reason other 
than termination of employment by the Corporation for cause after 2000, 
a Participant shall be entitled to receive payments under this Plan in 
accordance with the provisions of Section 7.  If a Participant is 
terminated for cause after 2000, the Participant shall forfeit any 
amount scheduled to be paid under Sections 7.1 and 7.2 after the date of 
termination of employment.

Section 9:          Beneficiary Designation
     9.1     A Participant's Beneficiary under the Plan, who shall be 
entitled to receive the amount, if any, payable under the Plan upon the 
Participant's death, shall be the Beneficiary designated, or deemed to 
be designated, by the Participant under the Compensation Deferral Plan.  
If a Participant does not participate in the Compensation Deferral Plan 
or if a Participant does participate in the Compensation Deferral Plan 
and has not designated or been deemed to have designated a Beneficiary 
thereunder, then any payments payable to the Participant under this Plan 
shall be distributed to the Participant's estate.  If the Corporation is 
in doubt as to the right of any person to receive such amount, the 
Corporation may retain such amount, without liability for any interest 
thereon, until the rights thereto are determined, or the Corporation may 
pay such amount into any court of appropriate jurisdiction and such 
payment shall be a complete discharge of the liability of the Plan and 
the Corporation therefor.

Section 10:          General Provisions
     10.1     A Participant may not assign any payment under this Plan.  
Any attempted assignment 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 personnel.  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 any payments under this Plan shall be no greater than 
the right of an unsecured general creditor of the Corporation.  There 
shall not vest in any Participant or Beneficiary any right, title, or 
interest in and to any specific assets of the Corporation.  All payments 
under this Plan 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 amount except to the 
extent this Plan is covered by the Benefits Protection Trust between the 
Corporation and State Street Bank and Trust Company, or any successor 
trust.
     10.3     Nothing contained in this 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.
