                                                                         ANNEX A
                                                                         -------

          Except as otherwise provided in the forms of Fixed Rate Note and
Floating Rate Note included herewith, the terms of the Notes shall be as follows

Rate Note included herewith and not otherwise defined herein are used herein as
so defined):

               (1)  A Series of Securities to be issued under the Indenture has
     been designated as the "Series D Medium-Term Notes" (such series is
     hereinafter referred to as the "Notes" and each individual obligation under
     such series, a "Note");

               (2)  The Notes shall constitute part of a single Series of
     Securities under the Indenture, which Series is not limited in aggregate
     principal amount, but is limited in aggregate initial public offering price
     to $400,000,000;

               (3)  The date(s) on which principal of each Note is payable shall
     be such date more than nine months from the date of issuance as is selected
     by the purchaser of such Note and agreed to by the Chairman of the Board,
     any President, any Vice President, the Treasurer, the Secretary, any
     Assistant Treasurer or any Assistant Secretary of the Company (the
     "Authorized Officers") at the time of issuance thereof, which date(s) shall
     be included in the form of such Note upon issuance thereof;

               (4)  The rate or rates and, if applicable, the method used to
     determine the rate, at which each Note shall bear interest (which may not
     in any case exceed the maximum rate permitted under applicable law) shall
     be determined by the Authorized Officers at the time of issuance thereof,
     which rate or rates or method for establishing the rate shall be included
     in the form of such Note upon issuance thereof.  Interest will accrue from
     the most recent date on which interest has been paid or duly provided for
     or if no interest has been paid or duly provided for, from the Interest
     Accrual Date, until the principal thereof has been paid or duly made
     available for payment (except as provided below).  Interest will be payable
     on each Interest Payment Date, which shall be on May 15 and November 15 of
     each year with respect to Fixed Rate Notes and on a date or dates as
     specified in Floating Rate Notes, and at a maturity as specified in the
     Note.  The interest so payable and punctually paid or duly provided for, on
     any Interest Payment Date will be paid to the person in whose name such
     Note is registered at the close of business on the Record Date for such
     Interest Payment date, which Record Date shall be the date 15 calendar days
     prior to each Interest Payment Date (whether or not a Business Day);

     redemption or repayment date) will be payable to the person to whom
     principal shall be payable.  The first payment of interest on any Note
     issued between a Record Date and an Interest Payment Date will be made on
     the Interest Payment Date following the next succeeding Record Date to the
     person in whose name such Note is registered on such next succeeding Record
     Date;

 
               (5)  Payment of the principal of each Note, any premium and the
     interest due on any Maturity Date (or any redemption or repayment date)
     will be made in immediately available funds upon surrender of such Note at
     the principal corporate trust office of the Trustee or at the office or
     agency of the Trustee maintained for that purpose in The City of New York,
     New York, or at such other paying agency as the Company may determine.

     other than interest due at maturity or on any date of redemption or
     repayment, will be made by U.S. dollar check mailed to the address of the
     person entitled thereto as such address shall appear in the Note register.
     A holder of U.S. $10,000,000 or more in aggregate principal amount of Notes
     having the same Interest Payment Date will be entitled to receive payments
     of interest, other than interest due at maturity or on any date of
     redemption or repayment, by wire transfer of immediately available funds if
     appropriate wire transfer instructions have been received by the Paying
     Agent in writing not less than 15 calendar days prior to the applicable
     Interest Payment Date.  If a Note is denominated in a Specified Currency
     other than U.S. dollars and payments of interest are to be made by wire
     transfer, such payments of interest thereon will be made by wire transfer
     of immediately available funds to an account maintained by the holder
     thereof with a bank located outside the United States if appropriate wire
     transfer instructions have been received by the Paying Agent in writing not
     less than 15 calendar days prior to the applicable Interest Payment Date.
     If such wire transfer instructions are not so received, such interest
     payments will be made by check payable in such Specified Currency mailed to
     the address of the person entitled thereto as such address shall appear in
     the Note register;

               (6)  Any Note may be redeemed or repurchased at the times and in

     terms and conditions as are set forth in such Note at the time of issuance
     thereof, as determined and certified to the Trustee by the Authorized
     Officers;

     determined and set forth at the time of issuance thereof;

               (9)  The principal of the Notes shall be payable upon declaration
     of acceleration of maturity pursuant to Section 6.2 of the Indenture,
     except that in the case of a Discount Security, the portion of the
     principal that shall be payable upon declaration of acceleration shall be
     such portion as is set forth in such Discount Note

     payment of principal of or interest on the Notes that are to be made in a
     Foreign Currency shall be as set forth in such Note at the time of issuance
     thereof, as determined and certified to the Trustee by the Authorized
     Officers;

     of or interest on any Note that is to be determined by reference to a
     commodity, commodity index, stock exchange index or financial index shall
     be as set forth in such Note at the time of issuance thereof, as determined
     and certified to the Trustee by the Authorized Officers;

               (14)  Any other terms of the Notes, which shall not be
     inconsistent with the Indenture, shall be as set forth in such Note at the
     time of issuance thereof, as determined and certified to the Trustee by the
     Authorized Officers;
