Indenture, the principal of this bond may be declared or may
become due and payable on the conditions, at the time, in the
manner and with the effect provided in the Indenture.

            No recourse shall be had for the payment of the
principal of or premium, if any, or interest on this bond, or for
any claim based hereon, or otherwise in respect hereof or of the
Indenture, to or against any incorporator, stockholder, director
or officer, past, present or future, as such, of the Company, or 

                              -12-

of any predecessor or successor company, either directly or
through the Company, or such predecessor or successor company, or
otherwise, under any constitution or statute or rule of law, or
by the enforcement of any assessment or penalty, or otherwise,
all such liability of incorporators, stockholders, directors and
officers, as such, being waived and released by the holder and
owner hereof by the acceptance of this bond and being likewise
waived and released by the terms of the Indenture.

            The bonds of this series are issuable only as
registered bonds without coupons in denominations of $1,000 and
authorized multiples thereof.  This bond is transferable by the
registered holder hereof, in person or by attorney duly
authorized, at the corporate trust office of the Trustee, in the
Borough of Manhattan, The City, County and State of New York, or
at such other place or places as the Company may designate by
resolution of the Board of Directors, but only in the manner and
upon the conditions prescribed in the Indenture, upon the
surrender and cancellation of this bond and the payment of
charges for transfer, and upon any such transfer a new registered
bond or bonds, without coupons, of the same series and maturity
date and for the same aggregate principal amount, in authorized
denominations, will be issued to the transferee in exchange
herefor.  The Company, the Trustee and any agent designated to
make transfers or exchanges of bonds of this series may deem and
treat the person in whose name this bond is registered as the
absolute owner for all purposes including the purpose of the
receipt of payment.  Registered bonds of this series shall be
exchangeable at said corporate trust office of the Trustee, or at
such other place or places as the Company may designate by
resolution of the Board of Directors, for registered bonds  of
other authorized denominations having the same aggregate
principal amount, in the manner and upon the conditions
prescribed in the Indenture.  Neither the Company nor the Trustee
nor any other agent designated for such propose shall be required
to make transfers or exchanges of bonds of this series during the
period between any interest payment date for such series and the
record date next preceding such interest payment date. 
Notwithstanding any provisions of the Indenture, no charge shall
be made upon any transfer or exchange of Bonds of this series
other than for any tax or taxes or other governmental charge
required to be paid by the Company.

            Bonds of this series are to be issued initially under a
book-entry only system and, except as hereinafter provided,
registered in the name of the Depository Trust Company, New York,
New York ("DTC") or its nominee, which shall be considered the
holder of all of the bonds of this series for all purposes of the
Indenture, including, without limitation, payment by the Company
of principal and interest on such bonds of this series and
receipt of notices and exercise of rights of holders of such
bonds of this series.  There shall be a single bond of this
series which shall be immobilized in the custody of DTC with the
owners of book entry interests in bonds of this series ("Book

                              -13-
 
Entry Interests") having no right to receive bonds of this series
in the form of physical securities or certificates.  Ownership of
Book-Entry Interests shall be shown by book entry on the system
maintained and operated by DTC, its participants (the
"Participants") and certain persons acting through the
Participants.  Transfers of ownership of Book-Entry Interests are
to be made only by DTC and the Participants by that book entry
system, the Company and the Trustee having no responsibility
therefor so long as bonds of this series are registered in the
name of DTC or its nominee.  DTC is to maintain records of the
positions of Participants are to maintain records of the
purchasers and owners of Book-Entry Interests.  If DTC or its
nominee determines not to continue to act as a depository for the
bonds of this series in connection with a book-entry only system,
another depository, if available, may act, instead and the single
bond of this series will be transferred into the name of such
other depository or its nominee, in which case the above
provisions will continue to apply but to the new depository.  If
the book-entry only system for bonds of this series is
discontinued for any reason upon surrender and cancellation of
the single bond of this series registered in the name of the then
depository or its nominee, new registered bonds of this series
will be issued in authorized denominations to the holders of
Book-Entry Interests in principal amounts coinciding with the
amounts of such Book-Entry Interests shown on the book-entry only
system immediately prior to the discontinuance thereof.  Neither
the Trustee nor the Company shall be responsible for the accuracy
of the interests shown on that system.

without any preference, distinction or priority as to lien or

difference in time of the actual authentication, delivery, issue,

that each and every bond now or hereafter authenticated and
delivered thereunder shall have the same lien, and so that the

            AND IT IS EXPRESSLY DECLARED that all bonds
authenticated and delivered and secured thereunder and hereunder
are to be issued, authenticated and delivered, and all said
premises, property, franchises and rights hereby and by the
Indenture conveyed, assigned, pledged or mortgaged, or intended

Company in and to any and all premises, property, franchises and
rights of every kind and description, real, personal and mixed,

any therein expressly excepted), are to be dealt with and
disposed of, under, upon and subject to the terms, conditions,
stipulations, covenants, agreements, trusts, uses and purposes in
the Indenture expressed, and it is hereby agreed as follows:

            Section 1.  There are hereby created two series of
bonds, one such series designated 6-5/8% Series of 1993 due 2004,
which shall also bear the descriptive title "First Mortgage Bond"
(said bonds being sometimes herein referred to as the "bonds of
the Thirty-Fifth Series"), and one such Series designated 7-5/8%
Series of 1993 due 2023, which shall also bear the descriptive
title "First Mortgage Bond" (said bonds being sometimes herein
referred to as the "bonds of the Thirty-Sixth Series")  and the
form of each such series shall be substantially as hereinbefore
set forth.  Bonds of the Thirty-Fifth Series shall mature on
January 1, 2004, and bonds of the Thirty-Sixth Series shall
mature on July 1, 2023. (Collectively herein the bonds of the
Thirty-Fifth Series and the bonds of the Thirty-Sixth Series are
sometimes referred to as the "bonds of the Thirty-Fifth and
Thirty-Sixth Series").  The bonds of the Thirty-Fifth and Thirty-
Sixth Series may be issued only as registered bonds without
coupons in denominations of $1,000 or such multiples thereof as
the Board of Directors shall approve, and delivery to the Trustee
for authentication shall be conclusive evidence of such approval. 
The serial numbers of bonds of the Thirty-Fifth and Thirty-Sixth
Series shall be such as may be approved by any officer of the
Company, the execution thereof by any such officer, by facsimile
signature or otherwise, to be conclusive evidence of such
approval.  Bonds of the Thirty-Fifth Series and bonds of the
Thirty-Sixth Series shall bear interest at the rate, until the
principal thereof shall have become due and payable, of 6-5/8%
per annum and 7-5/8% per annum, respectively, payable

                              -16-
 
semiannually on January 1, 1994 and on each July 1 and January 1
thereafter,  the principal of and the premium, if any, and the
interest on said bonds shall be payable 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 at the office or agency
of the Company in the Borough of Manhattan, The City, County and
State of New York, designated for that purpose.

            Except as provided in this Section 1, bonds of the
Thirty-Fifth and Thirty-Sixth Series shall be dated and bear
interest as provided in Section 2.03 of the Indenture; provided,
however, that, so long as there is no existing default in the
payment of interest on said bonds, any bond of the Thirty-Fifth
and Thirty-Sixth Series authenticated by the Trustee between an
interest payment date for bonds of such Series and the record
date, as hereinbelow defined, for such interest payment date
shall bear interest from such interest payment date and the
holder of any such bond shall not be entitled to payment of
interest on such interest payment date and shall have no claim
against the Company with respect thereto; provided, further, that
if and to the extent the Company, shall default in the payment of
the interest due on such interest payment date, then such bond
shall bear interest from the interest payment date next preceding
the date of such bond, to which interest has been paid, or, if
the Company shall be in default with respect to the interest due
January 1, 1994, then from July 1, 1993.

            Bonds of the Thirty-Fifth Series are not redeemable
prior to their maturity.

            The bonds of the Thirty-Sixth Series will not be

and accrued interest thereon to the date fixed for redemption,

amount thereof determined as set forth in the tabulation below
under the heading "Regular Redemption Premium" or (b) if redeemed
by the use of cash deposited pursuant to the sinking and
improvement fund or the maintenance and replacement provisions of
the Indenture or by the use of proceeds of released property, as
more fully set forth in the Indenture, a special redemption price
equal to the principal amount thereof and accrued interest
thereon to the date fixed for redemption:

     2014 and thereafter                      0.00

            The person in whose name any bond of the Thirty-Fifth
Series or Thirty-Sixth Series is registered at the close of
business on any record date (as hereinbelow defined) with respect
to any interest payment date shall be entitled to receive the

issued, directly or after immediate transactions, upon transfer
or exchange or in substitution thereof) is registered on a
subsequent record date for such payment established as
hereinafter provided.  A subsequent record date may be
established by the Company by notice mailed to the registered
holders of binds not less than ten days preceding such subsequent
record date, which shall be not less than five nor more than
thirty days prior to the subsequent interest payment date.  The
term "record date" as used in this Section with respect to any
regular interest payment date shall mean the December 15 or June
15, as the case may be, next preceding such interest payment
date, or, if such December 15 or June 15 shall be a legal holiday
or a day on which the banking institutions in the Borough of
Manhattan, The City, County and State of New York, are authorized
by law to close, the next preceding day which shall not be a
