                          shall be the immediately preceding April 1 (for April

                          October 1 (for October 15 payment dates).

         5.               Payments of principal of and interest on the Senior
                          Debentures represented by the Global Senior Notes
                          initially registered in the name of The Depository
                          Trust Company (the "Depositary") or its nominee shall
                          be made by the Company through the Trustee in
                          immediately available funds to the Depositary or its

                          equal to the greater of (i) 100% of their principal
                          amount or (ii) the sum of the present values of the
                          remaining scheduled payments of principal and

   2
                          (exclusive of interest accrued to the Redemption
                          Date) discounted to the Redemption Date on a
                          semiannual basis (assuming a 360-day year consisting
                          of twelve 30-day months) at the Treasury Rate plus 15
                          basis points, plus in either case accrued and unpaid
                          interest on the principal amount being redeemed to
                          the Redemption Date; provided, however, that
                          installments of interest on Senior Debentures that
                          are due and payable on an Interest Payment Date
                          falling on or prior to the relevant Redemption Date
                          shall be payable to the holders of such Senior
                          Debentures, or one or more Predecessor Securities,
                          registered as such at the close of business on the
                          relevant Regular Record Date according to their terms
                          and the provisions of the Indenture.

         "Treasury Rate" means, with respect to any Redemption Date for the
Senior Debentures, (a) the yield, under the heading that represents the average
for the immediately preceding week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication that is
published weekly by the Board of Governors of the Federal Reserve System and
that establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption "Treasury Constant Maturities,"
for the maturity corresponding to the Comparable Treasury Issue (if no maturity
is within three months before or after the Maturity Date, yields for the two
published maturities most closely corresponding to the Comparable Treasury
Issue shall be determined and the Treasury Rate shall be interpolated or
extrapolated from such yields on a straight-line basis, rounding to the nearest
month) or (b) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields,
the rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such Redemption Date.  The Treasury Rate shall be
calculated on the third Business Day preceding the Redemption Date.

         "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity comparable
to the remaining term of the Senior Debentures to be redeemed that would be
utilized, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Senior Debentures.

         "Independent Investment Banker" means Morgan Stanley & Co.
Incorporated or, if such firm is unwilling or unable to select the Comparable
Treasury Issue, an independent investment banking institution of national
standing appointed by the Trustee after consultation with the Company.

         "Comparable Treasury Price" means, with respect to any Redemption
Date, (a) the average of four Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (b) if the Trustee obtains  fewer than four such
Reference Treasury Dealer Quotations, the average of all such Quotations.

   3
         "Reference Treasury Dealer" means each of Morgan Stanley & Co.
Incorporated and Goldman, Sachs & Co. and their respective successors;
provided, however, that if either of the foregoing shall cease to be a primary
U.S. Government securities dealer in New York City (a "Primary Treasury
Dealer"), the Company will substitute therefor another Primary Treasury Dealer.

         "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Redemption Treasury Dealer at 5:00 p.m., New
York City time, on the third Business Day preceding such Redemption Date.

         7.               The Senior Debentures shall be represented by two
                          Global Senior Notes deposited with the Depositary and
                          registered in the name of the nominee of the
                          Depositary.

         8.               There shall be no mandatory sinking fund for the
                          payments of the Senior Debentures.

         9.               The Company shall be subject to all the covenants set
                          forth in Articles Eight and Ten of the Indenture with
                          respect to the Senior Debentures.

         10.              Article Thirteen of the Indenture shall apply to the
                          Senior Debentures.

         11.              As long as the Depositary or its nominee, or a
                          successor Depositary or its nominee, is the
                          registered owner of the Global Senior Notes, owners
                          of the beneficial interests in the Global Senior
                          Notes shall not be entitled to have the Senior
                          Debentures registered in their names and shall not
                          receive or be entitled to receive physical delivery
                          of Senior Debentures in definitive form.

                          the Trustee and initial Paying Agent and Registrar
                          for the Senior Debentures under the Indenture.

         13.              The Senior Debentures shall not be subordinated.  The
                          Senior Debentures shall be senior unsecured
                          obligations of the Company ranking pari passu with
                          other senior indebtedness of the Company.
