     --------
     (A)  Each Participant who shall retire under the conditions set 
          forth in Section 7 will receive an Annual Supplemental 
          Retirement Benefit paid from the general assets of the 
          Corporation for a period of fifteen years commencing as 
          provided herein.  Such benefit will be paid in consecutive 
          quarter yearly payments on the first business day of January, 
          April, July and October (hereinafter individually referred to 
          as the "Quarterly Payment Date") for the immediately 
          preceding calendar quarters ended, December 31, March 31, 
          June 30 and September 30, respectively.  The initial payment 
          shall be made on the first Quarterly Payment Date following 
          the Participant's Retirement, or, at the election of a 
          Disabled Participant, commencing upon any subsequent 
          Quarterly Payment Date which occurs while the Participant 
          remains Disabled, but in no event later than the Quarterly 
          Payment Date following the earlier of the Participant's 
          cessation of disability or the attainment of age 65.  
          Proration shall be made for a short calendar quarter and 
          calculated on a 90 day per quarter basis.  

     (B)  In the event of the death of a Participant after Retirement 
          and before the entire number of said quarterly payments have 
          been paid, such remaining unpaid quarterly payments will be 
          paid to the last beneficiary designated in writing by the 
          Participant to, and received by, the Pension Board or, in the
          absence or failure of any such designation or the designated 
          beneficiary fails to survive for the said fifteen year period, 
          to the surviving Spouse of the Participant, or in the absence 
          of such Spouse, to the Participant's estate.  In the event the 
          designated beneficiary fails to survive and the Participant's
          Spouse does not survive for the said fifteen years, the Pension 
          Board may elect to make a lump sum payment of the unpaid amount 
          to the Participant's estate, or the Spouse's estate, or the 
          beneficiary's estate, as the Pension Board may determine in its 
          sole discretion to be fair and equitable, said lump sum payment 
          being the present value of the remaining payments, determined in
          accordance with the average rate of interest published by the 
          Pension Benefit Guaranty Corporation for immediate annuities for 
          the 36 months immediately preceding the date of such payment.  




                                       E-10

     (C)  In the event of the death of a Participant before Retirement when 
          the Participant would have been eligible to receive retirement 
          benefits under either Section 7(A) or 7(B), the Normal or Early 
          Supplemental Retirement Benefit to which the Participant would 
          have been entitled had he retired on the date of his death will 
          be paid to the last beneficiary designated in writing by the 
          Participant to, and received by, the Pension Board or, in the 
          absence or failure of any such designation or the designated 
          beneficiary fails to survive for the said fifteen year period, to 
          the surviving Spouse of the Participant, or, in the absence of 
          such Spouse, to the Participant's estate.  Such benefit will be 
          determined as of the date of death of the Participant and will be 
          paid in accordance with the payment procedures in Section 5(A).  
          In the event the designated beneficiary fails to survive and the
          Participant's Spouse does not survive for the said fifteen years,  
          the Pension Board may elect to make a lump sum payment of the 
          unpaid amount to the Participant's estate, or the Spouse's estate, 
          or the beneficiary's estate, as the Pension Board may determine in 
          its sole discretion to be fair and equitable, said lump sum pay-
          ment being the present value of the remaining payments, determined 
          in accordance with the average rate of interest published by the 
          Pension Benefit Guaranty Corporation for immediate annuities for 
          the 36 months immediately preceding the date of such payment.  

     (D)  No benefit payable under this Plan shall be subject in any way to 
          alienation, sale, transfer, assignment, pledge, attachment, 
          garnishment, execution, or encumbrance of any kind, and any 
          attempt to accomplish the same shall be void and of no effect.  


6.   Annual Base Formula Retirement Benefit
     --------------------------------------
     The Annual Base Formula Retirement Benefit shall be calculated at the 
     date of Retirement or in the case of a Former Participant at the 
     termination of participation and will be equal to

          calculated by multiplying the "average monthly earnings" (as 
          determined for pension purposes under the General Retirement Plan) 
          by 12 (or in the event the Participant or Former Participant has
          insufficient service to create a Consecutive Five-Year Calculation 
          Period, the average annual earnings calculated from such years of 
          service and fractions thereof, rounded to the nearest month) [in 
          either event, if the Participant had eligible compensation reduced 
          under the General Retirement Plan to comply with section 401(a)(17) 
          of the Internal Revenue Code of 1986, and the regulations there-

          compensation plan of the Corporation, other than any deferred 
          compensation previously included in the definition of "earnings" 
          contained in the General Retirement Plan, such deferred and/or 
          reduced compensation shall be added, for the sole purpose of 
          determining the benefit under this Section, to the Participant's 
          earnings in the year the Participant would have been credited with 
          such earnings under the General Retirement Plan but for such 
          deferral and/or reduction],

                                       E-11

     
     (B)  multiplied by a percentage which is 

          (l)  five percent for each year of service, or fraction thereof, 
               with the Corporation up to a maximum of ten years, that an 
               individual has been designated a Participant in this Plan 
               subsequent to December 13, 1979, plus 

          (2)  (with respect to Participants and Former Participants who 
               became Participants before October 1, 1988) two percent for 
               each other year of service or fraction thereof with the
               Corporation, or its subsidiaries; or 

          (3)  (with respect to Participants and Former Participants who 
               became Participants on or after October 1, 1988 and retire 
               prior to January 1, 1997) 1.26 percent for each other year 
               of service or fraction thereof with the Corporation, or its
               subsidiaries; or

          (4)  (with respect to Participants and Former Participants who 
               became Participants on or after October 1, 1988 and retire 
               after December 31, 1996) 1.3 percent for each year of 
               service up to 20 years and 1.4 percent for each additional 
               year of service or fraction thereof with the Corporation, or 
               its subsidiaries; 

          provided, however, that the aggregate of the percentages of this 
          Subparagraph 6(B) shall not exceed the sum of 60% plus one-quarter 
          percent per year for each year or fraction thereof for such 
          service exceeding 30 years,

     (C)  reduced by the sum of the following (such reduction to commence and 
          be fixed as of the respective calculation dates hereinafter stated):  

          (l)  the Participant's accrued pension benefits calculated to be 
               payable from any other defined benefit pension plans (including 
               but not limited to the General Retirement Plan, the Benefit
               Equalization Plan, the Earnings Adjustment Plan, the Officers' 
               Supplemental Retirement Plan, and any pension plans from other 
               prior employment) as of the respective date or dates of earliest
               entitlement or, if later, the date of retirement under such 
               pension plans, before any actuarial reduction for option 
               election; provided, however, that any such reduction shall not 
               include the portion of any other pension benefit resulting from 
               the Participant's express contribution, nor any benefits attri-
               butable to a defined contribution entitlement and

          (2)  the amount of the Primary Social Security Retirement Benefit 
               calculated to be payable as of the date of earliest entitlement 
               or, if later, the date of Retirement hereunder.
