REVERSE OF SECURITY

                   Distributions payable on each Capital Security will be payable at a floating rate of interest per annum, which, with respect to any Distribution Period (as defined herein), will be equal to LIBOR, as determined on the LIBOR Determination Date for such Distribution Period (or, in the case of the first Distribution Period, will be 1.11%), plus 2.75% (the "Coupon Rate"); provided, however, that the Coupon Rate for any Distribution Period may not exceed the Interest Rate (as defined in the Indenture) for the related Interest Period (as defined in the Indenture). Distributions in arrears for more than one Distribution Period will bear interest thereon, compounded quarterly, at the applicable Coupon Rate for each Distribution Period thereafter (to the extent permitted by applicable law). The term "Distributions", as used herein, includes cash Distributions, any such compounded Distributions and any Additional Amounts payable on the Debentures, unless otherwise stated. A Distribution is payable only to the extent that payments are made in respect of the Debentures held by the Institutional Trustee and to the extent the Institutional Trustee has funds legally available in the Property Account therefor. The amount of Distributions payable for any Distribution Period will be computed on the basis of a 360-day year and the actual number of days elapsed in such Distribution Period.

                   Except as otherwise described below, Distributions on the Capital Securities will be cumulative, will accrue from the date of original issuance and will be payable quarterly in arrears on January 7, April 7, July 7 and October 7 of each year, commencing on July 7, 2004 (each, a "Distribution Payment Date"), and on any earlier date of redemption, subject, in each case, to the Business Day convention specified in the Declaration. The Debenture Issuer has the right under the Indenture to defer payments of interest on the Debentures by extending the interest payment period for up to 20 consecutive quarterly periods (each such extended interest payment period, together with all previous and future consecutive extensions thereof, is referred to herein as an "Extension Period") at any time and from time to time on the Debentures, subject to the conditions described below and in the Declaration and the Indenture. No Extension Period may end on a date other than a Distribution Payment Date or extend beyond the Maturity Date, any Optional Redemption Date or the Special Redemption Date, as the case may be. During any Extension Period, interest will continue to accrue on the Debentures, and interest on such accrued interest (such accrued interest and interest thereon referred to herein as "Deferred Interest") will accrue, at an annual rate equal to the Coupon Rate applicable during such Extension Period, compounded quarterly from the date such Deferred Interest would have been payable were it not for the Extension Period, to the extent permitted by applicable law. At the end of any Extension Period, the Debenture Issuer shall pay all Deferred Interest then accrued and unpaid on the Debentures; provided, however, that prior to the termination of any Extension Period, the Debenture Issuer may further extend such Extension Period, provided, that no Extension Period (including all previous and further consecutive extensions that are part of such Extension Period) shall exceed 20 consecutive quarterly periods. Upon the termination of any Extension Period and upon the payment of all Deferred Interest, the Debenture Issuer may commence a new Extension Period, subject to the requirements set forth herein and in the Declaration and the Indenture. No interest or Deferred Interest (except any Additional Amounts that may be due and payable) shall be due and payable during an Extension Period, except at the end thereof, but Deferred Interest shall accrue upon each installment of interest that would otherwise have been due and payable during such Extension Period until such installment is paid.

                   As a consequence of any Extension Period, Distributions will be deferred. If Distributions are deferred, the Distributions due shall be paid on the date that the related Extension Period terminates to Holders of the Capital Securities as they appear on the books and records of the Trust on the regular record date immediately preceding the Distribution Payment Date on which such Extension Period terminates to the extent that the Trust has funds legally available for the payment of such Distributions in the Property Account of the Trust.

                   The Capital Securities shall be redeemable, and shall be entitled to the Liquidation Distribution, as provided in the Declaration.
