                    Service, Inc. ("Moody's"), or their successors (as
                    provided in the last sentence of this paragraph 5),
                    and adjusted if necessary in response to changes in
                    a Rating.  The initial Applicable Rate (as
                    hereinafter defined) on the Debentures will be
                    
                                     -1-                    
                    
                                                               Exhibit (4)(d)



         
          9.125% per annum.  The Debentures shall bear
          interest at the initial Applicable Rate from
          December 1, 1989 to but excluding the earlier of
          the date of repayment or (except as provided below)
          the calendar day on which a change in rating
          category (as set forth in the table below) takes
          effect in either the S&P Rating or Moody's Rating
          (a "Rating Adjustment Date").  Beginning with the
          calendar day which is a Rating Adjustment Date if
          any (unless such Rating Adjustment Date occurs
          between a Record Date and an Interest Payment Date
          in which case beginning on such Interest Payment
          Date), and to but excluding the earlier of the date
          of repayment or next Rating Adjustment Date, if
          any, the Debentures shall bear interest at the rate
          per annum (the "Applicable Rate") set forth below
          opposite the lower of the S&P Rating and the
          Moody's Rating in effect at the close of business
          on that Rating Adjustment Date; provided that if
          only one such Rating is available on any Rating
          Adjustment Date, the Applicable Rate shall be
          determined solely by reference to such one Rating.

          If one or more Rating Adjustment Dates occur
          during any interest payment period, the Debentures
          shall bear interest for such interest payment
          period at the rate per annum equal to the weighted
          average of the Applicable Rates in effect during
          such interest payment period, calculated by
          multlplying each Applicable Rate by the number of
          days such Applicable Rates is in effect during each
          month of such interest payment period, determining
          the sum of such products and dividing such sum by
          the number of days in such interest payment period
          which shall be 180 days in all cases.  The
          Applicable Rate and interest on the  Debentures
          shall be computed on the basis of a year of twelve
          30-day months.   If neither S&P nor Moody's has
          issued a current Rating, or if the rating system
          
                                 -2-
         

           employed by either such organization is changed
           from that which is currently employed, then the
           Company shall, with the approval of the Trustee,
           designate such additional nationally recognized
           rating organization, or make such adjustments in
           the relationship between the Rating and the
           Applicable Rate, as are consistent with the above
           table;
           
               6.   Not later than 15 days after any change
           in the Applicable Rate, the Company shall cause the
           Trustee to give notice of such change to all
           holders by mailing a written notice of such change
           by first class mail to all holders as their names
           and addresses appear in the Security Register   In
           addition, the Company will, upon request of the
           holder of a Debenture, provide the Applicable Rate
           then in effect;
           
               7.    The principal of and interest on the
           Debentures shall be payable at the office or agency
           of the Company which will initially be the office
           of the agent of the Trustee at Bankers Trust
           Company, 4 Albany Street, New York, New York 10006,
           or at such other places as the Company may
           designate; provided, however, that at the option of
           the Company payment of interest may be made by
           check mailed to the address of the person entitled
           thereto as such address shall appear in the
           Security Register (as defined in the Indenture);
           
               8.    Except as provided in Sections 501 and
           502 of the Indenture, there is no option,
           obligation or right of the Company to redeem,
           purchase, repay or exchange any other securities
           for the Debentures prior to maturity;
           
                                   -3-
        

         
            9.     The provisions regarding defeasance set forth
         in Section 403 of the Indenture shall apply to the
         Debentures; provided that from and after the effective
         date of discharge described in such Section, the
         Applicable Rate shall be equal to the Applicable Rate in
         effect on the date prior to the deposit of money and/or
         U.S. Government Obligations with respect to the
         Debentures,  and such Applicable Rate shall not
         thereafter be affected by any change in the Rating.  For
         the purpose of determining the amount of money and/or
         U.S. Government Obligations required to be deposited
         with the Trustee in order to effect such a discharge,
         the interest rate on the Debentures shall be assumed to
         be (i) for the period beginning on the effective date of
         such discharge, such Applicable Rate and (ii) for the
         period beginning on the day of such deposit and ending
         on the date prior to the effective date of such
         discharge, the highest Applicable Rate indicated in
         paragraph 5 above; and
         
            10.    The provisions in Section 1007 of the
         Indenture shall not apply to the Debentures.
