and

               WHEREAS, Section 8 of the Mortgage provides that the form of
each series of bonds (other than the First Series) issued thereunder and of the
coupons to be attached to coupon bonds of such series shall be established by
Resolution of the Board of Directors of the Company and that the form of such
series, as established by said Board of Directors, shall specify the descriptive
title of the bonds and various other terms thereof, and may also contain such
provisions not inconsistent with the provisions of the Mortgage as the Board of
Directors may, in its discretion, cause to be inserted therein expressing or
referring to the terms and conditions upon which such bonds are to be issued
and/or secured under the Mortgage; and

               WHEREAS, Section 130 of the Mortgage provides, among other
things, that any power, privilege or right expressly or impliedly reserved to or

at the time unrestricted or to additional restriction if already restricted, and
the Company may enter into any further covenants, limitations or restrictions
for the benefit of any one or more series of bonds issued thereunder and provide

the Company may cure any ambiguity contained therein or in any supplemental
indenture or may establish the terms and provisions of any series of bonds other
than the First Series, by an instrument in writing executed and acknowledged by
the Company in such manner as would be necessary to entitle a conveyance of real
estate to record in all of the states in which any property at the time subject
to the Lien of the Mortgage shall be situated; and the Trustee is further
authorized by said Section 130 to join with the Company in the execution of any
such instrument or instruments, and such instrument, executed and acknowledged
as aforesaid, shall be delivered to the Trustee and thereupon any modification
of the provisions of the Mortgage therein set forth, authorized by said
Section 130, shall be binding upon the parties to the Mortgage, their successors
and assigns, and the holders of the bonds and coupons thereby secured; provided,
however; anything therein contained to the contrary notwithstanding, said
Section 130 shall not be construed to permit any act, waiver; surrender or
restriction adversely affecting any bonds then Outstanding under the Mortgage;
and

               WHEREAS, in Section 42 of the Mortgage, the Original Mortgagor
covenanted that it would execute and deliver such supplemental indenture or
indentures and such further instruments and do such further acts as might be
necessary or proper to carry out more effectually the purposes of the Mortgage
and to make subject to the Lien of the Mortgage any property thereafter
acquired, made or constructed and intended to be subject


                                          5



to the Lien thereof, and to transfer to any new trustee or trustees or
co-trustee or co-trustees, the estates, powers, instruments or funds held in
trust thereunder; and

               WHEREAS, the Company now desires to create three new series of
bonds and (pursuant to Section 130 of the Mortgage) to add to its covenants and
agreements contained in the Mortgage certain other covenants and agreements to
be observed by it; and

               WHEREAS, the execution and delivery by the Company of this
Fifty-sixth Supplemental Indenture has been duly authorized by the Board of
Directors by appropriate Resolutions;

               NOW, THEREFORE, THIS INDENTURE WITNESSETH:

                             FIFTY-NINTH SERIES OF BONDS

       SECTION 2.01.  There shall be a series of bonds designated "First
Mortgage Bonds, Adjustable Rate Replacement Series" (herein sometimes referred
to as the "Fifty-ninth Series"), each of which shall also bear the descriptive
title First Mortgage Bond, and the form thereof, which shall be established by
Resolution of the Board of Directors of the Company, shall contain suitable
provisions with respect to the matters hereinafter in this Section specified.
Bonds of the Fifty-ninth Series shall mature on the maturity date, and in
principal amounts corresponding to the principal amounts, of first mortgage and
collateral trust bonds designated "Adjustable Rate Replacement Series," issued
under the Company's Mortgage and Deed of Trust, dated as of January 9, 1989, as
amended and supplemented, to Chemical Bank, as trustee, on the basis of such
bonds of the Fifty-ninth Series.  Bonds of the Fifty-ninth Series shall be
issued as fully registered bonds in the denomination of One Thousand Dollars
and, at the option of the Company, in any multiple or multiples of One Thousand
Dollars (the exercise of such option to be evidenced by the execution and
delivery thereof); they shall bear no interest; and the principal of each such
bond shall be payable at the office or agency of the Company in the Borough of
Manhattan, The City of New York, in such coin or currency of the United States
of America as at the time of payment is legal tender for public and private
debts.  Bonds of the Fifty-ninth Series shall be dated as in Section 10 of the
Mortgage provided.

       (I)     Bonds of the Fifty-ninth Series shall be redeemable either at
the option of the Company or pursuant to the requirements of the Mortgage
(including, among other things, the provisions of Sections 39 or 74 of the
Mortgage or with the proceeds of released property pursuant to Section 71 of the
Mortgage).

       (II)    At the option of the registered owner, any bonds of the Fifty-
ninth Series, upon surrender thereof for cancellation at the office or agency of
the Company in the Borough of Manhattan, The City of New York, together with a
written instrument of transfer whenever required by the Company duly executed by
the registered owner or by his duly authorized attorney shall (subject to the
provisions of Section 12 of the Mortgage) be exchangeable for a like aggregate
principal amount of bonds of the same series of other authorized denominations.

               Bonds of the Fifty-ninth Series shall be transferable (subject
to the provisions of Section 12 of the Mortgage and to the limitations set forth
in this Fifty-sixth Supplemental Indenture), upon the surrender thereof for
cancellation, together with a written instrument of transfer in form approved by
the registrar duly executed by the


                                          9



registered owner or by his duly authorized attorney, at the office or agency of
the Company in the Borough of Manhattan, The City of New York.  Upon any
transfer or exchange of bonds of the Fifty-ninth Series, the Company may make a
charge therefor sufficient to reimburse it for any tax or taxes or other
governmental charge, as provided in Section 12 of the Mortgage, but the Company
hereby waives any right to make a charge in addition thereto for any exchange or
transfer of bonds of the Fifty-ninth Series.

               The Trustee may conclusively presume that the obligation of the
Company to pay the principal of the bonds of the Fifty-ninth Series as the same
shall become due and payable shall have been fully satisfied and discharged
unless and until it shall have received a written notice from the trustee under
the Company's Mortgage and Deed of Trust, dated as of January 9, 1989, as
amended and supplemented, to Chemical Bank, as trustee, signed by the President,
a Vice President, an Assistant Vice President or a Trust Officer of such
trustee, stating that interest or principal due and payable on any bonds issued
under said Mortgage and Deed of Trust has not been fully paid and specifying the
amount of funds required to make such payment.

               Bonds of the Fifty-ninth Series shall be initially issued in the
name of Chemical Bank, as trustee under the Company's Mortgage and Deed of
Trust, dated as of January 9, 1989, as amended and supplemented, and shall not
be transferable, except to any successor trustee under said Mortgage and Deed of
Trust.

               After the execution and delivery of this Fifty-sixth
Supplemental Indenture and upon compliance with the applicable provisions of the
Mortgage, as supplemented, it is contemplated that there shall be issued bonds
of the Fifty-ninth Series in an aggregate principal amount not to exceed Six
Million Six Hundred Seventeen Thousand Dollars ($6,617,000).

                                     ARTICLE III

provisions with respect to the matters hereinafter in this Section specified.
