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 the coupon bonds, if any, of such series shall be
established by Resolution of the Board of Directors of the Company; 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 that
such series may also contain such provisions not inconsistent with the
provisions of


                                          4



the Mortgage, as supplemented, 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 120 of the Mortgage provides, among other

subjected to any restriction if 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 that a breach thereof shall be equivalent
to a default under the Mortgage, or the Company may cure any ambiguity contained
therein, or in any supplemental indenture, or may (in lieu of establishment by
Resolution as provided in Section 8 of the Mortgage) 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 120 to join with
the Company in the execution of 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 120, 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 not withstanding, said Section 120 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 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 the provisions of Section 120 of the Mortgage) to add to
its covenants and agreements contained in the Mortgage, as heretofore
supplemented, certain other covenants and agreements to be observed by it; and

                                      ARTICLE II

                             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, 64 or 87 of the
Mortgage or with the Proceeds of Released Property).

      (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


                                          9



Borough of Manhattan, The City of New York, shall 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-fourth 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 registered owner or by his, her or its 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-fourth
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).

authorized denominations.

              The Trustee may conclusively presume that the obligation of the
Company to pay the principal of the bonds of the Sixtieth 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

of the Sixtieth Series in an aggregate principal amount not to exceed Twenty-
