                                     PART I.
                     CREATION OF THREE HUNDRED THIRTY-EIGHTH
                            SERIES OF BONDS, GENERAL
                          AND REFUNDING MORTGAGE BONDS,
                               2004 SERIES D BONDS

TERMS OF BONDS OF 2004 SERIES D.

      SECTION 1. The Company hereby creates the three hundred thirty-eighth
series of bonds to be issued under and secured by the Original Indenture as
amended to date and as further amended by this Supplemental Indenture, to be
designated, and to be distinguished from the bonds of all other series, by the
title "General and Refunding Mortgage Bonds, 2004 Series D" (elsewhere herein
referred to as the "bonds of 2004 Series D"). The aggregate principal amount of
bonds of 2004 Series D shall

                                       13

<PAGE>

be limited to two hundred million dollars ($200,000,000), except as provided in
Sections 7 and 13 of Article II of the Original Indenture with respect to
exchanges and replacements of bonds, and except further that the Company may,
without the consent of any holder of the bonds of 2004 Series D, "reopen" the
bonds of 2004 Series D so as to increase the aggregate principal amount
outstanding to equal the aggregate principal amount of Notes (as defined below)
outstanding upon a "reopening" of the series, so long as any additional bonds of
2004 Series D have the same tenor and terms as the bonds of 2004 Series D
established hereby..

      Subject to the release provisions set forth below, each bond of 2004
Series D is to be irrevocably assigned to, and registered in the name of, J.P.
Morgan Trust Company, National Association, as trustee, or a successor trustee
(said trustee or any successor trustee being hereinafter referred to as the
"Note Indenture Trustee"), under the collateral trust indenture, dated as of
June 30, 1993 (the "Note Indenture"), as supplemented, between the Note
Indenture Trustee and the Company, to secure payment of the Company's 2004
Series D 5.40% Senior Notes due 2014 (for purposes of this Part I, the "Notes").

      The bonds of 2004 Series D shall be issued as registered bonds without
coupons in denominations of a multiple of $1,000. The bonds of 2004 Series D
shall be issued in the aggregate principal amount of $200,000,000, shall mature
on August 1, 2014 (subject to earlier redemption or release) and shall bear
interest at the rate of 5.40% per annum, payable in arrears on February 1 and
August 1 of each year (commencing February 1, 2005), until the principal thereof
shall have become due and payable and thereafter until the Company's obligation
with respect to the payment of said principal shall have been discharged as
provided in the Indenture.

                                       14

<PAGE>

      The bonds of 2004 Series D shall be payable as to principal, premium, if
any, and interest as provided in the Indenture, but only to the extent and in
the manner herein provided. The bonds of 2004 Series D shall be payable, both as
to principal and interest, at the office or agency of the Company in the Borough
of Manhattan, The City and State of New York, in any coin or currency of the
United States of America which at the time of payment is legal tender for public
and private debts.

      Except as provided herein, each bond of 2004 Series D shall be dated the
date of its authentication and interest shall be payable on the principal
represented thereby from the February 1 or August 1 next preceding the date
thereof to which interest has been paid on bonds of 2004 Series D, unless the
bond is authenticated on a date to which interest has been paid, in which case
interest shall be payable from the date of authentication, or unless the date of
authentication is prior to February 1, 2005, in which case interest shall be
payable from July 15, 2004.

      The bonds of 2004 Series D in definitive form shall be, at the election of
the Company, fully engraved or shall be lithographed or printed in authorized
denominations as aforesaid and numbered 1 and upwards (with such further
designation as may be appropriate and desirable to indicate by such designation
the form, series and denomination of bonds of 2004 Series D). Until bonds of
2004 Series D in definitive form are ready for delivery, the Company may
execute, and upon its request in writing the Trustee shall authenticate and
deliver in lieu thereof, bonds of 2004 Series D in temporary form, as provided
in Section 10 of Article II of the Indenture. Temporary bonds of 2004 Series D,
if any, may be printed and may be issued in authorized denominations in
substantially the form of definitive bonds of 2004 Series D, but without a
recital of redemption prices and with such omissions, insertions and variations
as may be appropriate for temporary bonds, all as may be determined by the
Company.

      Interest on any bond of 2004 Series D that is payable on any interest
payment date and is punctually paid or duly provided for shall be paid to the
person in whose name that bond, or any previous bond to the extent evidencing
the same debt as that evidenced by that bond, is registered at the close of
business on the regular record date

                                       15

<PAGE>

for such interest, which regular record date shall be the fifteenth calendar day
(whether or not a business day) next preceding such interest payment date. If
the Company shall default in the payment of the interest due on any interest
payment date on the principal represented by any bond of 2004 Series D, such
defaulted interest shall forthwith cease to be payable to the registered holder
of that bond on the relevant regular record date by virtue of his having been
such holder, and such defaulted interest may be paid to the registered holder of
that bond (or any bond or bonds of 2004 Series D issued upon transfer or
exchange thereof) on the date of payment of such defaulted interest or, at the
election of the Company, to the person in whose name that bond (or any bond or
bonds of 2004 Series D issued upon transfer or exchange thereof) is registered
on a subsequent record date established by notice given by mail by or on behalf
of the Company to the holders of bonds of 2004 Series D not less than ten (10)
days preceding such subsequent record date, which subsequent record date shall
be at least five (5) days prior to the payment date of such defaulted interest.

      Bonds of 2004 Series D shall not be assignable or transferable except as
may be set forth under Section 405 of the Note Indenture or in the supplemental
note indenture relating to the Notes, or, subject to compliance with applicable
law, as may be involved in the course of the exercise of rights and remedies
consequent upon an Event of Default under the Note Indenture. Any such transfer
shall be made upon surrender thereof for cancellation at the office or agency of
the Company in the Borough of Manhattan, The City and State of New York,
together with a written instrument of transfer (if so required by the Company or
by the Trustee) in form approved by the Company duly executed by the holder or
by its duly authorized attorney. Bonds of 2004 Series D shall in the same manner
be exchangeable for a like aggregate principal amount of bonds of 2004 Series D
upon the terms and conditions specified herein and in Section 7 of Article II of
the Indenture. The Company waives its rights under Section 7 of Article II of
the Indenture not to make exchanges or transfers of bonds of 2004 Series D
during any period of ten days next preceding any redemption date for such bonds.

      Bonds of 2004 Series D, in definitive and temporary form, may bear such
legends as may be

                                       16

<PAGE>

necessary to comply with any law or with any rules or regulations made pursuant
thereto or as may be specified in the Note Indenture.

      Upon payment of the principal or premium, if any, or interest on the
Notes, whether at maturity or prior to maturity by redemption or otherwise, or
upon provision for the payment thereof having been made in accordance with
Article V of the Note Indenture, bonds of 2004 Series D in a principal amount
equal to the principal amount of such Notes, shall, to the extent of such
payment of principal, premium or interest, be deemed fully paid and the
obligation of the Company thereunder to make such payment shall forthwith cease
and be discharged, and, in the case of the payment of principal and premium, if
any, such bonds shall be surrendered for cancellation or presented for
appropriate notation to the Trustee.

RELEASE.

      From and after the Release Date (as defined in the Note Indenture), the
bonds of 2004 Series D shall be deemed fully paid, satisfied and discharged and
the obligation of the Company thereunder shall be terminated. On the Release
Date, the bonds of 2004 Series D shall be surrendered to and canceled by the
Trustee. The Company covenants and agrees that, prior to the Release Date, it
will not take any action that would cause the outstanding principal amount of
the bonds of 2004 Series D to be less than the then outstanding principal amount
of the Notes.

REDEMPTION OF BONDS OF 2004 SERIES D.

      SECTION 2. Bonds of 2004 Series D shall be redeemed on the respective
dates and in the respective principal amounts which correspond to the redemption
dates for, and the principal amounts to be redeemed of, the Notes.

      In the event the Company elects to redeem any Notes prior to maturity in
accordance with the provisions of the Note Indenture, the Company shall on the
same date redeem bonds of 2004 Series D in principal amounts and at redemption
prices corresponding to the Notes so redeemed. The Company agrees to give the
Trustee notice of any such redemption of bonds of 2004 Series D on the same date
as it gives notice of redemption of Notes to the Note Indenture Trustee.

                                       17

<PAGE>

REDEMPTION OF BONDS OF 2004 SERIES D IN EVENT OF ACCELERATION OF NOTES.

      SECTION 3. In the event of an Event of Default under the Note Indenture
and the acceleration of all Notes, the bonds of 2004 Series D shall be
redeemable in whole upon receipt by the Trustee of a written demand (hereinafter
called a "Redemption Demand") from the Note Indenture Trustee stating that there
has occurred under the Note Indenture both an Event of Default and a declaration
of acceleration of payment of principal, accrued interest and premium, if any,
on the Notes, specifying the last date to which interest on the Notes has been
paid (such date being hereinafter referred to as the "Initial Interest Accrual
Date") and demanding redemption of the bonds of said series. The Trustee shall,
within five days after receiving such Redemption Demand, mail a copy thereof to
the Company marked to indicate the date of its receipt by the Trustee. Promptly
upon receipt by the Company of such copy of a Redemption Demand, the Company
shall fix a date on which it will redeem the bonds of said series so demanded to
be redeemed (hereinafter called the "Demand Redemption Date"). Notice of the
date fixed as the Demand Redemption Date shall be mailed by the Company to the
Trustee at least ten days prior to such Demand Redemption Date. The date to be
fixed by the Company as and for the Demand Redemption Date may be any date up to
and including the earlier of (x) the 60th day after receipt by the Trustee of
the Redemption Demand or (y) the maturity date of such bonds first occurring
following the 20th day after the receipt by the Trustee of the Redemption
Demand; provided, however, that if the Trustee shall not have received such
notice fixing the Demand Redemption Date on or before the 10th day preceding the
earlier of such dates, the Demand Redemption Date shall be deemed to be the
earlier of such dates. The Trustee shall mail notice of the Demand Redemption
Date (such notice being hereinafter called the "Demand Redemption Notice") to
the Note Indenture Trustee not more than ten nor less than five days prior to
the Demand Redemption Date.

      Each bond of 2004 Series D shall be redeemed by the Company on the Demand
Redemption Date therefore upon surrender thereof by the Note Indenture Trustee
to the Trustee at a redemption price equal to the principal amount thereof plus
accrued interest thereon at the rate specified for such bond from the Initial
Interest Accrual Date to the Demand Redemption Date plus an amount equal to the
aggregate premium, if any, due and payable on such

                                       18
<PAGE>


Demand Redemption Date on all Notes; provided, however, that in the event of a
receipt by the Trustee of a notice that, pursuant to Section 602 of the Note
Indenture, the Note Indenture Trustee has terminated proceedings to enforce any
right under the Note Indenture, then any Redemption Demand shall thereby be
rescinded by the Note Indenture Trustee, and no Demand Redemption Notice shall
be given, or, if already given, shall be automatically annulled; but no such
rescission or annulment shall extend to or affect any subsequent default or
impair any right consequent thereon.

      Anything herein contained to the contrary notwithstanding, the Trustee is
not authorized to take any action pursuant to a Redemption Demand and such
Redemption Demand shall be of no force or effect, unless it is executed in the
name of the Note Indenture Trustee by its President or one of its Vice
Presidents.

[FORM OF REVERSE OF BOND]

      This bond is one of an authorized issue of bonds of the Company, unlimited
as to amount except as provided in the Indenture hereinafter mentioned or any
indentures supplemental thereto, and is one of a series of General and Refunding
Mortgage Bonds known as 2004 Series D, limited to an aggregate principal amount
of $200,000,000, except as otherwise provided in the Indenture hereinafter
mentioned. This bond and all other bonds of said series are issued and to be
issued under, and are all equally and ratably secured (except insofar as any
sinking, amortization, improvement or analogous fund, established in accordance
with the provisions of the Indenture hereinafter mentioned, may afford
additional security for the bonds of any particular series and except as
provided in Section 3 of

                                       21

Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly
executed by the Company to J. P. Morgan Trust Company, National Association, as
successor in interest to Bank One, National Association as Trustee, to which
Indenture and all indentures supplemental thereto (including the Supplemental
Indenture dated as of July 1, 2004) reference is hereby made for a description
of the properties and franchises mortgaged and conveyed, the nature and extent
of the security, the terms and conditions upon which the bonds are issued and
under which additional bonds may be issued, and the rights of the holders of the
bonds and of the Trustee in respect of such security (which Indenture and all
indentures supplemental thereto, including the Supplemental Indenture dated as
of July 1, 2004, are hereinafter collectively called the "Indenture"). As
provided in the Indenture, said bonds may be for various principal sums and are
issuable in series, which may mature at different times, may bear interest at
different rates and may otherwise vary as in said Indenture provided. With the
consent of the Company and to the extent permitted by and as provided in the
Indenture, the rights and obligations of the Company and of the holders of the
bonds and the terms and provisions of the Indenture, or of any indenture
supplemental thereto, may be modified or altered in certain respects by
affirmative vote of at least eighty-five percent (85%) in amount of the bonds
then outstanding, and, if the rights of one or more, but less than all, series
of bonds then outstanding are to be affected by the action proposed to be taken,
then also by affirmative vote of at least eighty-five percent (85%) in amount of
the series of bonds so to be affected (excluding in every instance bonds
disqualified from voting by reason of the Company's interest therein as
specified in the Indenture); provided, however, that, without the consent of the
holder hereof, no such modification or alteration shall, among other things,
affect the terms of payment of the principal of or the interest on this bond,
which in those respects is unconditional.

      This bond is redeemable prior to the Release Date upon the terms and
conditions set forth in the Indenture, including provision for redemption upon
demand of the Note Indenture Trustee following the occurrence of an Event of
Default under the Note Indenture and the acceleration of the principal of the
Notes.

                                       22
<PAGE>

      Under the Indenture, funds may be deposited with the Trustee (which shall
have become available for payment), in advance of the redemption date of any of
the bonds of 2004 Series D (or portions thereof), in trust for the redemption of
such bonds (or portions thereof) and the interest due or to become due thereon,
and thereupon all obligations of the Company in respect of such bonds (or
portions thereof) so to be redeemed and such interest shall cease and be
discharged, and the holders thereof shall thereafter be restricted exclusively
to such funds for any and all claims of whatsoever nature on their part under
the Indenture or with respect to such bonds (or portions thereof) and interest.

      In case an event of default, as defined in the Indenture, shall occur, the
principal of all the bonds issued thereunder may become or be declared due and
payable, in the manner, with the effect and subject to the conditions provided
in the Indenture.

      Upon payment of the principal of, or premium, if any, or interest on, the
Notes, whether at maturity or prior to maturity by redemption or otherwise, or
upon provision for the payment thereof having been made in accordance with
Article V of the Note Indenture, bonds of 2004 Series D in a principal amount
equal to the principal amount of such Notes, and having both a corresponding
maturity date and interest rate shall, to the extent of such payment of
principal, premium or interest, be deemed fully paid and the obligation of the
Company thereunder to make such payment shall forthwith cease and be discharged,
and, in the case of the payment of principal and premium, if any, such bonds of
said series shall be surrendered for cancellation or presented for appropriate
notation to the Trustee.

      This bond is not assignable or transferable except as set forth under
Section 405 of the Note Indenture or in the supplemental indenture relating to
the Notes, or, subject to compliance with applicable law, as may be involved in
the course of the exercise of rights and remedies consequent upon an Event of
Default under the Note Indenture. Any such transfer shall be made by the
registered holder hereof, in person or by his attorney duly authorized in
writing, on the books of the Company kept at its office or agency in the Borough
of Manhattan, The City and State of New York,

                                       23
<PAGE>

upon surrender and cancellation of this bond, and thereupon, a new registered
bond of the same series of authorized denominations for a like aggregate
principal amount will be issued to the transferee in exchange therefor, and this
bond with others in like form may in like manner be exchanged for one or more
new bonds of the same series of other authorized denominations, but of the same
aggregate principal amount, all as provided and upon the terms and conditions
set forth in the Indenture, and upon payment, in any event, of the charges
prescribed in the Indenture.

      From and after the Release Date (as defined in the Note Indenture), the
bonds of 2004 Series D shall be deemed fully paid, satisfied and discharged and
the obligation of the Company thereunder shall be terminated. On the Release
Date, the bonds of 2004 Series D shall be surrendered to and cancelled by the
Trustee. The Company covenants and agrees that, prior to the Release Date, it
will not take any action that would cause the outstanding principal amount of
the bond of 2004 Series D to be less than the then outstanding principal amount
of the Notes.

      No recourse shall be had for the payment of the principal of or the
interest on this bond, or for any claim based hereon or otherwise in respect
hereof or of the Indenture, or of any indenture supplemental thereto, against
any incorporator, or against any past, present or future stockholder, director
or officer, as such, of the Company, or of any predecessor or successor
corporation, either directly or through the Company or any such predecessor or
successor corporation, whether for amounts unpaid on stock subscriptions or by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise howsoever; all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released by every holder or owner hereof, as more fully
provided in the Indenture.
