Supplemental Indenture, by becoming such Holders shall be deemed
to have consented to the Twenty Eighth Supplemental Indenture

     Redemption

     This Series AC Bond is not redeemable at the Option of the
Company, as a whole or in part, at any time.

     Redemption at Option of Holder

     The Holder hereof shall have the option to require the
Company to redeem all or any portion (in integral multiples of
$1,000) of this Series AC Bond on February 1, 2002 (the
"Redemption Date") at a Redemption Price equal to 100% of the
principal hereof to be redeemed, plus interest accrued, if any,
to the Redemption Date.  To exercise such option, the Holder
shall deliver or cause to be delivered to the Trustee, and the
Trustee shall receive at its office in the Borough of Manhattan,
the City of New York, during the period beginning December 1,
2001 and ending at 5:00 P.M. (New York City time) on December 31,
2001 (or, if December 31, 2001 is not a business day, on the next
succeeding business day), this Series AC Bond with the form
entitled "Option to Require Redemption on February 1, 2002" on
the reverse side hereof duly completed.  Any such exercise of
such option shall be irrevocable.  All questions as to the
validity, form, eligibility (including time of receipt) and
acceptance of this Series AC Bond for redemption shall be
determined by the Company, whose determination shall be final and
binding.

     Pursuant to the provisions of Section 8.05 of the Indenture,
the Company may request the Trustee to apply moneys deposited
with the Trustee ("Trust Moneys") for various reasons toward the
redemption of those Bonds, including payment of premium and
accrued interest, selected by the Company.  In the Thirtieth
Supplemental Indenture, the Company has covenanted not to request
the Trustee to apply any Trust Moneys to the redemption of the
Series AC Bonds prior to February 1, 2010.

     Pursuant to the provisions of Section 8.08 of the Indenture,
the Series AC Bonds are further subject to redemption, in whole
or in part, by the Trustee applying certain Trust Moneys which
have been held by the Trustee for a period of over two years. 
Any such redemption is made pro rata among the series of Bonds
then outstanding in the ratio of principal amount.  Redemption is
at 100 percent of principal, plus any premium due at the time of
redemption and accrued interest to redemption date.

     If this Bond or any portion thereof ($1,000 or a multiple)
shall be duly called for redemption as provided in the Indenture,
this Bond or such portion thereof shall (unless the Company shall
default in the payment of the redemption price) cease to bear
interest from and after the date fixed for redemption.

     Upon any partial redemption of this Bond, this Bond may, at
the option of the registered holder hereof, be either (a)
surrendered to the Trustee in exchange for one or more new Bonds
of this Series for the principal amount of the unredeemed portion
of this Bond or (b) submitted to the Trustee for notation hereon
by the Trustee of the payment of the portion of the principal
hereof so called for redemption.

     If an Event of Default, as defined in the Indenture, shall
occur, the principal of this Bond may become or be declared due
and payable, in the manner and with the effect provided in the
Indenture.

     This Bond is transferable by the registered owner hereof in
person or by attorney authorized in writing, at said principal
corporate trust office of the Trustee, upon surrender for
cancellation of this Bond and on payment of charges, and upon any
such transfer a new Bond or Bonds, of the same series, for the
same aggregate principal amount, will be issued to the transferee
in exchange herefor.

     First Mortgage Bonds, Series AC, 8.06%, due February 1,
2010, are issuable as fully registered Bonds without coupons of
the denominations of $1,000 and any multiple of $1,000 which may
be executed by the Company and delivered to the Trustee for
authentication and delivery.  The Series AC Bonds, upon surrender
thereof to the Trustee at its principal corporate trust office in
the Borough of Manhattan, The City of New York, are exchangeable
for other Bonds of the same series in such authorized
denomination or denominations in the same aggregate principal
amount, as may be requested by the holders surrendering the same.

     The Company and the Trustee may deem and treat the person in
whose name this Bond is registered as the absolute owner hereof,
for the purpose of receiving payment of or on account of the
principal hereof and interest due hereon, and neither the Company
nor the Trustee shall be affected by any notice to the contrary. 
Interest payable herein shall be paid to the person in whose name
the Bond is registered at the close of business on January 15 or
July 15 (whether or not on a business day) next preceding the
interest payment date, except for defaulted interest and
unmatured accrued interest on the Series AC Bonds called for
redemption on a date other than an interest payment date.

     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,
stockholder, director or officer, as such, past, present or
future, of the Company or of any predecessor or successor
corporation, either directly or through the Company or any
predecessor or successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or by any legal or equitable proceeding
or otherwise howsoever; all such liability being, by the
acceptance hereof and as a part of the consideration for the
issuance hereof, expressly waived and released by every holder
hereof, as more fully provided in the Indenture; provided,
however, that nothing herein or in the Indenture contained shall
be taken to prevent recourse to and the enforcement of the
liability, if any, of any shareholder or any stockholder or
subscriber to capital stock upon or in respect of shares of
capital stock not fully paid up.

     This Bond shall not be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have
been signed by the Trustee, or its successor as Trustee, under
the Indenture.


     IN WITNESS WHEREOF, the Company has caused this Bond to be
signed in its name by its President or one of its Vice
Presidents, and its corporate seal to be impressed or imprinted
hereon and attested by its Secretary or one of its Assistant
Secretaries.

Additions acquired by such successor corporation at the date upon
which it became such successor corporation.

          Among other properties not constituting Property
Additions under the foregoing provisions, the term "Property

               (7)  any item of property constructed or acquired
to replace a similar item of property whose retirement has not
been credited to plant account; or any property whose cost has
been charged, or is properly chargeable, to repairs or
maintenance or other operating expense account, or whose cost has
not been charged, or is not properly chargeable, to plant
account;

               (8)  any Excepted Property unless the Company
elects to cause the Excepted Property to be subject to the Lien
of the Indenture; or

               (9)  going concern value or good will, or

     1.05.     Additions Credit not Bonded Property.  Clause (2)
of Paragraph K of Section 4.01 of Article Four is hereby amended
so as to read as follows:

          (2)  All Property Additions which have been made the
basis for the authentication and delivery of Bonds or the release
of any Bonded Property from the Lien of this Indenture or the
withdrawal of any Bonded Cash (or Unbonded Cash, if withdrawn
under Section 8.03) from the Trustee, but not including Additions
Credits within the meaning of Paragraph N of this Section.


     1.06.     Addition Credit--Definition.  Paragraph N of
Section 4.01 of Article Four of the Indenture is hereby amended
so as to read as follows:

          N.   "Additions Credit."

               If and whenever any Net Bondable Additions or
Gross Bondable Additions are certified or made a part of an
application to the Trustee for any purpose under this Indenture,
any amount is in excess of that required for such purpose, the
excess amount shall constitute an Additions Credit and may be
carried forward and used as Property Additions for additional
certifications and applications under this Indenture.  The
Company shall have the right, at any time and from time to time,
to establish an Additions Credit by delivering to the Trustee the
Certificates, Opinions and Other Instruments which would be
required to be delivered to the Trustee under Section 4.02 B,
Clauses (1) through (11), (13) and (14) and Sections 4.02,
Paragraphs C, D and E of this Indenture.


     1.07.     Certifiable Net Earnings.  Paragraph O of Section
4.01 of Article Four of the Indenture as amended by Section 3.04
of Article Three of the Third Supplemental Indenture, and as
amended by Section 1.03 of Article One of the Nineteenth
Supplemental Indenture is hereby further amended so as to read as
follows:

          O.  The "Certifiable Net Earnings" of the Company for
any particular period shall be computed and ascertained by
deducting from the total of the Gross Operating Revenues of the
Company for such period the following:

               All operating expenses and other proper charges
(other than those charged to capital accounts or surplus)
including (a) all Federal, state and local taxes (other than
taxes in respect of income or profits and other taxes imposed on
or measured by income or profits); and (b) rentals, insurance,
current repairs and maintenance; but excluding (i) provisions for
reserves for renewals, replacements, depreciation, depletion or
retirement of property (or any expenditures therefor), or
provisions for amortization of property, (ii) expenses or
provisions for interest on any indebtedness of the Company, for
the amortization of debt discount, premium, expense or loss on
reacquired debt, for any maintenance and replacement, improvement
or sinking fund or other device for the retirement of any
indebtedness, or for other amortization, (iii) expenses or
provisions for any nonrecurring charge to income or to retained
earnings of whatever kind or nature (including without limitation
the recognition of expense or impairment due to the
nonrecoverability of assets or expense), whether or not recorded
as a nonrecurring charge in the Company's books of account, and
(iv) provisions for any refund of revenues previously collected
or accrued by the Company subject to possible refund.

          The Gross Operating Revenues of the Company shall
consist of Gross Utility Operating Revenues of the Company, plus
the Net Non-Operating Income of the Company.  The term "Gross
Utility Operating Revenues" of the Company shall mean the
aggregate gross operating revenues derived from the operation of
the utility properties owned or leased by the Company.  The term
"Net Non-Operating Income" of the Company shall mean net income
derived from but not necessarily limited to the following:  (a)
merchandising, jobbing and contract work; (b) rental of
non-utility properties; (c) interest and dividend income
including dividends from Subsidiaries; (d) allowance for funds
used during construction; and (e) other miscellaneous
non-operating income; provided, however, that profits or losses
resulting from the sale, abandonment or other disposition of
capital assets or securities of the Company and the Company's
equity in the undistributed earnings of Subsidiaries, shall not
be taken into account in the calculation of Net Non-Operating
Income.

          Subject to the foregoing provisions of this Section,
all determinations of earnings pursuant to this Indenture shall
be made, and all balance sheets and other financial statements to
be delivered hereunder shall be prepared, in accordance with the
practice prescribed by any regulatory authority having
jurisdiction over the Company or other lawfully prescribed
practice or, in the absence of any practice prescribed by law, in
accordance with sound accounting practice and, where consistent
with such practice and with the foregoing provisions of this
Section, on the same basis as that used in preparing the
financial statements included in the annual report of the Company
for the preceding fiscal year.


     1.08.     Property Additions Certificate--Amendment to
Conform to Other Provisions.  Clauses (10) and (12) of Paragraph
B of Section 4.02 of Article Four of the Indenture is hereby
amended so as to read as follows:

          (10) That no part of the Property Additions described
in said Certificate is property the construction or acquisition
of which under the provisions of Section 4.01 is not permitted to
be made the basis of the authentication and delivery of Bonds
under this Article.

          (12) Whether there is any unused Additions Credit which
the Company desires to use, in whole or in part, as a basis for
the authentication and delivery of the Bonds then applied for,
and if so, a statement of the entire amount which the Company so
desires to use, of each such unused Additions Credit.


     1.09.     Earnings-to-Interest Coverage Requirements. 
Paragraph F of Section 4.02 of Article Four of the Indenture as
previously amended by Section 1.04 of the Nineteenth Supplemental
Indenture is hereby amended so as to read as follows:

          F.   A Net Earnings Certificate of the Company,
complying with the provisions of Section 1.02, dated not more
than 45 days prior to the application for the authentication and
delivery of such Bonds, certified by an Accountant, and setting
forth:

               (1)  The amount of the Certifiable Net Earnings of
the Company, for a period of 12 consecutive calendar months
within the 18 calendar months immediately preceding the date on
which the application for the authentication and delivery of the
Bonds is made, and stating separately the Gross Utility Operating
Revenues and the Net Non-Operating Income and the operating
expenses of the Company and other deductions from such Gross
Utility Operating Revenues and Net Non-Operating Income pursuant
to Paragraph O of Section 4.01, with the principal subdivisions
thereof.

               (2)  The aggregate amount of the annual "Interest
Charges on Bonds and Prior Lien Debt" of the Company, which term
shall mean the annual interest charges on

                    (a)  all Bonds outstanding hereunder at the
date of said Certificate, provided, however, that in the case of
any Bonds which shall at such time be pledged as security for any
indebtedness of the Company, the amount of the annual interest
charges on such pledged Bonds shall be deemed to be either the
amount of the annual interest charges on such indebtedness or the
amount of the annual interest charges on such pledged Bonds,
whichever shall be greater; and

                    (b)  all Bonds the authentication and
delivery of which is applied for in such application and in any
other pending application; and

                    (c)  all indebtedness secured by a lien upon
the Trust Estate, or any part thereof, prior to the lien of this
Indenture, other than a Prepaid Lien;

          provided, however, that there shall be excluded from
such computation the annual interest charges on any Bonds or
indebtedness which is to be paid, redeemed or otherwise retired,
or provision for the retirement of which is to be made, so that
the same will cease to be outstanding prior to or concurrently
with the authentication and delivery of the Bonds then applied
for.

               (3)  That the amount of the Certifiable Net
Earnings of the Company set forth as provided by Clause (1) of
this Paragraph have been at least equal to two (2) times the
aggregate amount of the annual Interest Charges on Bonds and
Prior Lien Debt of the Company as provided by Clause (2) of this
Paragraph.

               (4)  That such Certifiable Net Earnings have been
computed and ascertained as provided in Paragraph O of Section
4.01.

          If the annual Interest Charges on Bonds and Prior Lien
Debt shall be increased after the date of the Earnings
Certificate hereinabove in this Paragraph described, and before
the authentication and delivery of the Bonds then applied for,
the Company will file with the Trustee a new Earnings Certificate
showing the amount of said annual Interest Charges on Bonds and
Prior Liens as so increased--it being the intention hereof that
no Bonds shall be authenticated and delivered under the
provisions of this Article, unless the ratio provided for by
Clause (3) of this Paragraph shall have been established with
respect to the aggregate amount of the annual Interest Charges on
Bonds and Prior Liens of the Company as constituted at the time
of the authentication and delivery of the Bonds then applied for;
but the Trustee shall, subject to the provisions of Section
15.02, be entitled to assume, in the absence of such new Earnings
Certificate, that the aggregate amount of the annual Interest
Charges on Bonds and Prior Lien Debt of the Company, as
constituted at the time of the authentication and delivery of the
Bonds then applied for, are as stated in the Earnings Certificate
filed with the Trustee as aforesaid.

          The Earnings Certificate provided for in this Paragraph
shall be certified by an Independent Public Accountant selected
by the Company and approved by the Trustee, in the exercise of
reasonable care, if, but only if, the aggregate principal amount
of the Bonds to be authenticated and delivered on the basis
thereof and of other Bonds authenticated and delivered since the
commencement of the then current calendar year (other than those
with respect to which an Earnings Certificate is not required or
with respect to which an Earnings Certificate verified by an
Independent Public Accountant has previously been furnished) is
10% or more of the aggregate principal amount of the Bonds at the
time outstanding.


     1.10.     Summary Certificate.  Paragraph G of Section 4.02
of Article Four of the Indenture is hereby amended so as to read
as follows:

          G.   A summary certificate and computation of the
Company complying with the provisions of Section 1.02,
determining the Net Bondable Additions in conformity with the
provisions of this Indenture as amended.


     1.11.     Amount of Property Additions Required for New
Bonds.  Section 4.03 of Article Four of the Indenture is hereby
amended so as to read as follows:

          SECTION 4.03.  Upon compliance with the provisions of
Section 4.02, the Trustee shall authenticate and deliver Bonds in
an aggregate principal amount up to, but not exceeding seventy
percent (70%) of the amount of Net Bondable Additions shown by
the summary certificate and computation filed pursuant to
Paragraph G of Section 4.02.


     1.12.     Additional Authorization to Issue Bonds.  The
Indenture is amended by the addition of the following Section
4.04 to Article Four of the Indenture.

          SECTION 4.04.  Notwithstanding anything in this
Indenture to the contrary, upon the Written Order of the Company,
the Trustee shall authenticate and deliver Bonds in an aggregate
principal amount up to, but not exceeding seventy percent (70%)
of

               A.   the total amount of Property Additions which
the Company certifies to the Trustee as of May 1, 1994 and as of
each May 1 thereafter to meet the requirements of Section 9.06
until such time that Section 9.06 is deleted by the execution of
the Twenty Eighth Supplemental Indenture; and

               B.   fourteen and two-tenths percent (14.2%) of
the total amount of all Property Additions certified to the
Trustee and used as Bondable Additions for the issuance of Bonds
during the period beginning May 1, 1994 and ending on the
execution date of the Twenty Eighth Supplemental Indenture.

     The Company shall furnish the Trustee a Certificate of the
Company referencing and documenting the amount of Property
Additions previously certified and used as provided at Paragraphs
A and B of this Section, a summary certificate and computation
determining the amount of Bonds that may be issued under this
Section 4.04 and an Opinion of Counsel as required by Paragraph I
of Section 4.02; provided that subparagraph (1) thereunder shall
refer to the basis of this Section 4.04 rather than Net Bondable
Additions and subparagraphs (2), (3), (4) and (5) are not to be
included in such opinion.


     1.13.     Release of Property from Indenture.  Section 7.02
of Article Seven of the Indenture is hereby amended so as to read
as follows:


          SECTION 7.02.

               A.   Definition of "Fair Value."  For the purposes
of this Section 7.02, "Fair Value" when applied to property is
its value as determined without deduction for any Prior Liens
upon such property and without deduction to reflect that such
property may be of value only to the Company or another operator
of the Trust Estate as a whole, which value may be determined
without physical inspection by use of accounting and engineering
records and other data maintained by, or available to, the
Company.

               B.   Release Based on Bond Ratio.  Unless an Event
of Default shall have occurred and be continuing, upon receipt of
a Written Order of the Company requesting the release of any of
the Trust Estate pursuant to this Paragraph B, the Trustee shall
execute and deliver to the Company the documents and instruments
described in Paragraph B, releasing from the Lien of this
Indenture any of the Trust Estate if the Fair Value of all of the
Trust Estate (excluding the Trust Estate to be released but
including any Trust Estate to be acquired by the Company with the
proceeds of, or otherwise in connection with, such release)
stated on the Engineer's certificates delivered pursuant to
Clause 2 of Paragraph B and Clause (3) of Paragraph B, equals or

aggregate principal amount of Bonds outstanding at the date of
such Written Order of the Company as stated on the Certificate of
the Company delivered pursuant to Clause (4) of Paragraph B, upon
receipt by the Trustee of:

                    (1)  appropriate documents and instruments

Paragraph B in connection with such release, (ii) the Fair Value,
in the opinion of the signer of such Engineer's certificate, of
(A) all of the Trust Estate, and (B) the Trust Estate to be
released, in each case as of a date not more than 90 days prior
to the date of such Written Order of the Company, and (iii) that
in the judgment of such signers, such release (A) will not
materially adversely affect the Company's Electric Business, and
(B) will not impair the security under this Indenture in
contravention of the provisions hereof;

acquired by the Company with the proceeds of, or otherwise in
connection with, such release, an Engineer's certificate, dated
the date of such Written Order of the Company, as to the Fair
Value, as of a date not more than 90 days prior to the date of
such Written Order of the Company, of the Property Additions
being so acquired (and if within six months prior to the date of
acquisition by the Company of the Property Additions being so
acquired, any property included within such Property Additions
had been used or operated by others than the Company in a
business similar to that in which it has been or is to be used or
operated by the Company, and the Fair Value thereof to the
Company, as set forth in such Engineer's certificate, is not less
than one percent (1%) of the aggregate principal amount of Bonds
then outstanding, such certificate shall be an Independent
Engineer's Certificate); 

                    (4)  a Certificate of the Company, dated the
date of such Written Order of the Company, stating (i) that the
aggregate principal amount of Bonds outstanding at the date of

with, such release) stated on the Engineer's certificate filed
pursuant to Clause (2) of Paragraph B equals or exceeds an amount
equal to twenty-fourteenths (20/14) of such aggregate principal
amount, and (ii) that, to the knowledge of the signer, no Event
of Default has occurred and is continuing; and

                    (5)  an Opinion of Counsel complying with the
provisions of Section 1.02 stating that the instruments which
have been or are delivered to the Trustee conform to the
requirements of this Indenture and constitute sufficient
authority under this Indenture for the Trustee to execute and

the preceding Paragraph B, the release from the Lien of this
Indenture of any of the Trust Estate, unless an Event of Default
shall have occurred and be continuing, upon receipt of a Written
Order of the Company requesting the release of any of the Trust
Estate pursuant to this Paragraph C, the Trustee shall execute

               D.   Release by Deposit of Cash, Purchase Money
Obligations or Property Additions.  If the Company is unable, or
elects not, to obtain, in accordance with Paragraphs B or C, the
release from the Lien of this Indenture of any of the Trust
Estate, unless an Event of Default shall have occurred and be
continuing, upon receipt and deposit of a Written Order of the
Company requesting the release of any of the Trust Estate
pursuant to this Paragraph D and those items at Clause (2) in
this Paragraph D, the Trustee shall execute and deliver to the
Company the documents and instruments described in Clause (1) of
Paragraph D releasing from the Lien of this Indenture the Trust
Estate described in the Written Order of the Company.

                    (1)  appropriate documents and instruments

                         (ii)   the consideration received or to
be received by the Company therefor (valuing purchase money
obligations at their principal amount and property received in
exchange at its Fair Value as stated in said certificate),

          provided, however, that in lieu of all or any part of
such cash, the Company shall have the right to deposit with or
deliver to the Trustee any of the following:

Fair Value (as certified as above set forth) of the property
covered by such purchase money mortgage, which purchase money
obligations and the mortgages securing the same, shall be duly
assigned to the Trustee and shall be received by the Trustee at
the principal amount thereof in lieu of cash; provided, however,
that the Trustee shall not accept any such purchase money
obligations in lieu of cash as provided in this Clause if thereby
the aggregate principal amount of all purchase money obligations
received by the Trustee pursuant to this Clause and at the time
held by the Trustee would equal or exceed 10 percent of the
principal amount of all Bonds then outstanding hereunder.

                    (b)  A Certificate of the trustee or other
holder of a Prior Lien on all or any part of the property to be

representing proceeds of the sale of such property, have been
deposited with such trustee or other holder pursuant to the
requirements of such Prior Lien, provided, however, that the
aggregate of the cash and principal amount of purchase money
obligations so certified at any one time shall in no event exceed
the principal amount of the Prior Lien Obligations outstanding
thereunder, less any amounts then held by the trustee or other
holder of such Prior Lien other than for the payment or
redemption of Prior Lien Obligations not deemed outstanding under
the provisions of Section 4.01; and such certificate shall be

                    (c)  The Certificates, Opinions and Other

been made the basis for the release of any Unbonded Property from
the lien of this Indenture or for the withdrawal of any Unbonded
Cash from the Trustee or from the trustee or other holder of a
Prior Lien, or to repair, replace, or restore insured Unbonded
Property which shall have been damaged or destroyed but the

                         (iv)   If no part of the property to be
released is Bonded Property and such property or any part thereof
is subject to a Prior Lien, the Property Additions then so
certified may be subject to the same Prior Lien, and the Property
Additions Certificate required by Paragraph B of Section 4.02 and
the Opinion of Counsel required by Paragraph I of Section 4.02
may be modified accordingly.

                    Such Certificates, Opinions and Other
Instruments shall be received by the Trustee in lieu of cash up
to the amount of the Gross Bondable Additions so certified to the
Trustee.

                    (3)  An Opinion or Opinions of Counsel,

obligations, if any, delivered to the Trustee or to the trustee
or other holder of a Prior Lien pursuant to subparagraph (a) of
Clause (2) of Paragraph D of this Section are valid obligations

constituting a direct lien upon all the property to be released,
or upon the portion thereof described, free and clear of all
prior liens, charges or encumbrances, except any Prior Liens or
other charges or encumbrances prior to the lien of this Indenture
which may have existed on the property to be released immediately

(a) of Clause (2) of Paragraph D of this Section, any cash or
purchase money obligations shall be certified to have been
deposited with the trustee or other holder of a Prior Lien,
stating that the property to be released, or a specified portion
