                PRELIMINARY PROSPECTUS DATED AUGUST     , 1998


                                 $100,000,000

                           SOUTH JERSEY GAS COMPANY
                      SECURED MEDIUM TERM NOTES, SERIES A
                                        
                            ______________________
     South Jersey Gas Company (the "Company") intends to offer and sell from
time to time its Secured Medium Term Notes, Series A (the "Notes"), in an
aggregate principal amount up to $100,000,000 and having maturities ranging from
1 year to 40 years from date of issue. The Notes will be issued only in fully-
registered form, in minimum denominations of $1,000 and integral multiples of
$1,000 in excess thereof.  Unless otherwise indicated in the applicable Pricing
Supplement (as defined below), interest on each Note will be payable
semiannually in arrears on May 1 and November 1 at a fixed rate determined by
the Company and agreed upon by the purchaser thereof at or prior to the time of
sale. The purchase price, aggregate principal amount, interest rate, stated
maturity date, optional redemption provisions and any other material terms not
described herein of each issue of Notes will be set forth in an accompanying
supplement to this Prospectus (each, a "Pricing Supplement"). See "Description
of Notes."

     Prior to the Substitution Date (as defined herein), the Notes will be
serviced and secured as to the payment of the principal thereof and interest
thereon by the Company's First Mortgage Bonds, 10% Medium Term Notes Series A
(the "Pledged Bond") in an aggregate principal amount equal to $100,000,000
issued and pledged by the Company and delivered to the Note Trustee (as defined
herein) in accordance with the provisions of the Note Indenture (as defined
herein). The principal amount of the Pledged Bond deemed outstanding will at all
times be equal to the outstanding principal amount of the Notes. The Pledged
Bond will be deemed to bear interest corresponding to the required payments of
interest in respect of the Notes. Payments of principal and interest in respect
of the Notes will constitute payments on the Pledged Bond. The Pledged Bond
constitutes a separate series of the Company's First Mortgage Bonds, all of
which are secured by a lien on substantially all of the property owned by the
Company. See "Description of the Pledged Bond." On the Substitution Date, the
Pledged Bond will cease to secure the Notes, and, at the option of the Company,
the Notes either will become unsecured general obligations of the Company or
will be secured by first mortgage bonds issued under a mortgage other than the
Company's current mortgage indenture. See "Description of Notes -- Security;
Substitution Date."

     Each Note will be represented by a Global Note (each, a "Global Note")
registered in the name of The Depository Trust Company, as depository ("DTC" or
the "Depository"), or its nominee, unless otherwise specified in the applicable
Pricing Supplement. Beneficial interests in Global Notes will be shown on, and
transfers thereof will be effected only through, records maintained by the
Depository and its participants. Global Notes will not be issuable in
certificate form except under the limited circumstances described herein. See
"Description of Notes -- Certificated Notes."

</TABLE>

     The ratio of earnings to fixed charges represents, on a pre-tax basis, the

                                USE OF PROCEEDS

     Unless otherwise specified in the applicable Pricing Supplement, the net
proceeds from the sale of the Notes will be used by the Company to retire short-
term debt and to fund capital expenditure requirements. At June 30, 1998, the
Company had $72.3 million of short-term debt outstanding with a weighted-average
interest cost of 5.8%, with maturities not exceeding one month.

                           DESCRIPTION OF SECURITIES

     The Notes may be issued in one or more series (i) secured by the Company's
first mortgage bonds issued under the Company's current mortgage indenture or
(ii) following the Substitution Date (as defined below), as either unsecured
notes or as notes secured by the Company's first mortgage bonds issued under a
mortgage indenture other than the Company's current mortgage indenture. On the
Substitution Date, any outstanding Notes secured by the Company's first mortgage
bonds when issued will cease to be secured by first mortgage bonds issued under
the Company's current mortgage indenture and, at the Company's option, either
(a) will become unsecured general 

                                      -4-
<PAGE>
 
obligations of the Company or (b) will be secured by the Company's first
mortgage bonds issued under a mortgage indenture other than the Company's
current mortgage indenture.

     The Notes will be issued under an indenture (the "Note Indenture"), the
form of which is an exhibit to the Registration Statement of which this
Prospectus is a part, between the Company and The Bank of New York, as trustee
(the "Note Trustee"), and are described below under the caption "Description of
Notes." Prior to the Substitution Date, a Series of first mortgage bonds
designated as "South Jersey Gas Company First Mortgage Bonds, 10% Medium Term
Notes Series A" (the "Pledged Bond") will be issued under the Indenture of First
Mortgage, dated October 1, 1947, as heretofore supplemented and amended by
supplemental indentures and a new Twenty-Second Supplemental Indenture (the "New
Supplement") (such Indenture of First Mortgage, as supplemented, is herein
referred to as the "Mortgage"), all from the Company to The Bank of New York, as
successor trustee to Guaranty Bank (the "Mortgage Trustee") and pledged to the
Note Trustee under the Note Indenture to secure the Notes. The Pledged Bond to
be issued under the Mortgage is described below under the caption "Description
of the Pledged Bond."

     There is no requirement, under either the Note Indenture, or the Mortgage
(collectively, the "Indentures"), that future issues of debt securities of the
Company be issued under the Indenture, and, subject to certain restrictions
following the Substitution Date which are described in "Description of Notes-
Limitations on Liens" the Company will be free to employ other indentures or
documentation, containing provisions different from those included in the
Indenture or applicable to one or more issues of Notes, in connection with
future issues of such other debt securities.

                             DESCRIPTION OF NOTES

GENERAL

     The following summaries of certain provisions of the Note Indenture do not
purport to be complete and are subject to, and qualified in their entirety by,
all of the provisions of the Note Indenture which is incorporated herein by
reference and the form of which is an exhibit to the Registration Statement of
which this Prospectus is a part. References to Section numbers under this
caption are references to the Section numbers of the Note Indenture.

     Until the Substitution Date (as defined below), the Notes will be secured
by the Pledged Bond issued under the Mortgage and delivered by the Company to
the Note Trustee. See "Security; Substitution Date." ON THE SUBSTITUTION DATE
(AS DEFINED BELOW), THE NOTES WILL CEASE TO BE SECURED BY THE PLEDGED BOND AND,
AT THE COMPANY'S OPTION, EITHER (I) WILL BECOME UNSECURED GENERAL OBLIGATIONS OF
THE COMPANY OR (II) WILL BE SECURED BY THE COMPANY'S FIRST MORTGAGE BONDS (THE
"SUBSTITUTED PLEDGED BONDS") ISSUED UNDER A MORTGAGE INDENTURE OTHER THAN THE
MORTGAGE (A "SUBSTITUTED MORTGAGE"). The Note Indenture provides that, in
addition to the Notes offered hereby, additional notes may be issued thereunder,
without limitation as to aggregate principal amount, provided that, prior to the
Substitution Date, the amount of Notes that may be issued cannot exceed the
aggregate principal amount of first mortgage bonds that the Company is able to
issue under the Mortgage. See "Description of the Pledged Bond--Issuance of
Additional Bonds."

     The Note Indenture provides that the Notes will be issued in one or more
series, may be issued at various times, may have differing maturity dates and
may bear interest at differing rates; provided that Notes which are secured by
the Pledged Bond will bear interest at a rate not to exceed 10%, the stated
interest rate of the Pledged Bond. The Pricing Supplement applicable to each
series and issue of Notes will set forth any variation in the terms and
provisions of such Notes from those described in this Prospectus. Unless
otherwise indicated in the applicable Pricing Supplement, the Notes will be
denominated in United States currency in minimum denominations of $1,000 and
integral multiples thereof.

     Unless otherwise indicated in the applicable Pricing Supplement, there are
no provisions in the Note Indenture or the Notes that require the Company to
redeem, or permit the holders to cause a redemption of, the Notes or that
otherwise protect the holders in the event that the Company incurs substantial
additional indebtedness (except for certain restrictions on the Company's
ability to create, assume or incur certain liens after the Substitution Date, as
described in "Limitations on Liens") whether or not in connection with a change
in control of the Company. However, under current law, any change in control
transaction that involves the incurrence of additional long-term 

                                      -5-

indebtedness (as notes, first mortgage bonds or otherwise) by the Company would
require approval of state utility regulatory authorities and, possibly, of
federal utility regulatory authorities.

REGISTRATION, TRANSFER AND EXCHANGE

     Notes of any series will be exchangeable for one or more Notes of the same
series and issue of any authorized denominations and of a like aggregate
principal amount and tenor. (Section 2.6).

     Unless otherwise indicated in the applicable Pricing Supplement, Notes may
be presented for registration of transfer (duly endorsed or accompanied by a
duly executed written instrument of transfer), at the office of the Note Trustee
maintained for such purpose with respect to any series of Notes and referred to
in the applicable Pricing Supplement, without service charge but upon the
payment of any taxes and other governmental charges as described in the Note
Indenture. Such transfer or exchange will be effected upon being satisfied with
the documents of title and indemnity of the person making the request. (Sections
2.6 and 2.7).

     In the event of any redemption of Notes of any series, the Note Trustee
will not be required to exchange or register a transfer of any Notes of such
series selected, called or being called for redemption except, in the case of
any Note to be redeemed in part, the portion thereof not to be so redeemed.
(Section 2.6). See "Book-Entry System."

CERTIFICATED NOTES

     Each Note will be represented by a Global Note registered in the name of
the Depository, or its nominee, unless otherwise specified in the applicable
Pricing Supplement. The Notes represented by the Global Note are exchangeable
for certificated Notes in definitive form of like tenor as such Notes in
denominations of U.S.$1,000 and integral multiples thereof if (i) the Depository
notifies the Company that it is unwilling or unable to continue as Depository
for the Global Note or if at any time the Depository ceases to be a clearing
agency registered under the Exchange Act or (ii) the Company in its discretion,
at any time, determines not to have all of the Notes represented by the Global
Note. Any Note that is exchangeable pursuant to the preceding sentence is
exchangeable for certificated Notes issuable in authorized denominations and
registered in such names as the Depository shall direct. Subject to the
foregoing, the Global Note is not exchangeable, except for a Global Note of the
same aggregate denomination to be registered in the name of the Depository or
its nominee.

PAYMENT AND PAYING AGENTS

     Principal of and interest on Notes issued in the form of Global Notes will
be paid in the manner described below under the caption "Book-Entry System."
Unless otherwise indicated in the applicable Pricing Supplement, interest on
Notes that are in the form of certificated securities will be paid by wire
transfer of clearinghouse funds or by check mailed to the person entitled
thereto at such person's address as it appears in the register for the Notes
maintained by the Note Trustee; however, a holder of Notes of one or more series
under the Note Indenture in the aggregate principal amount of $10,000,000 or
more having the same interest payment dates will be entitled to request to
receive payments of interest on such series by wire transfer of immediately
available funds to a bank located within the continental United States if an
appropriate request including wire transfer instructions has been received by
the Note Trustee on or prior to the applicable regular record date in accordance
with the Note Indenture. Unless otherwise indicated in the applicable Pricing
Supplement, the principal of, and interest at maturity on Notes in the form of
certificated Notes will be payable in immediately available funds at the office
of the Note Trustee upon proper presentment and surrender thereof. (Section
2.12).

     All moneys paid by the Company to a paying agent for the payment of
principal of, or interest, on any Note which remain unclaimed at the end of one
year after such principal or interest shall have become due and payable will be
repaid to the Company and the holder of such Note will thereafter look only to
the Company for payment thereof (Section 5.4).

SECURITY; SUBSTITUTION DATE

     Until the Substitution Date (as defined below), the Notes will be secured
by the Pledged Bond issued and delivered by the Company to the Note Trustee. See
"Description of the Pledged Bond."

     THE "SUBSTITUTION DATE" WILL BE THE DATE THAT ALL FIRST MORTGAGE BONDS OF
THE COMPANY ISSUED AND OUTSTANDING UNDER THE MORTGAGE OTHER THAN THE PLEDGED
BOND (THE "FIRST MORTGAGE BONDS") HAVE BEEN RETIRED (AT, BEFORE OR AFTER THE
MATURITY THEREOF) THROUGH PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE
FIRST MORTGAGE BONDS DEEMED TO BE PAID WITHIN THE MEANING OF THE MORTGAGE). ON
THE SUBSTITUTION DATE, THE NOTE TRUSTEE WILL DELIVER TO THE COMPANY FOR
CANCELLATION THE PLEDGED BOND, AND THE COMPANY WILL CAUSE THE NOTE TRUSTEE TO
PROVIDE NOTICE TO ALL HOLDERS OF NOTES OF THE OCCURRENCE OF THE SUBSTITUTION
DATE. AS A RESULT, ON THE SUBSTITUTION DATE, THE PLEDGED BOND WILL CEASE TO
SECURE THE NOTES, AND, AT THE OPTION OF THE COMPANY, THE NOTES EITHER (I) WILL
BECOME UNSECURED GENERAL OBLIGATIONS OF THE COMPANY OR (II) WILL BE SECURED BY
SUBSTITUTED PLEDGED BONDS (Section 4.11).

LIMITATIONS ON LIENS

     Following the Substitution Date, the Company shall cause the Mortgage to be
closed and the Company shall not issue any additional Bonds under the Mortgage.
In addition, following the Substitution Date, except as described below and
unless Substituted Pledged Bonds are issued to secure the Notes, the Company may
not create, assume or incur any mortgage, pledge, lien or security interest
(collectively referred to in this context as "mortgages") upon any real property
interest or other depreciable asset which is used in the Company's gas utility
business, whether owned at the Substitution Date or thereafter acquired, to
secure any indebtedness for money borrowed other than indebtedness with
maturities of twelve months or less ("Debt"), without effectively securing all
Notes (other than such Notes, if any, which shall by their terms be expressly
excluded from such provision) equally and ratably with such Debt; provided,
however, that this restriction will not apply to:

               (a)  mortgages on any property existing at the time of the
          property's acquisition, including acquisition by means of merger or
          consolidation (but excluding any extension of or addition to such
          property unless the terms of the mortgage as of the date of
          acquisition of such property provide that such mortgage shall be
          secured by such extensions or additions);

               (b)  mortgages to secure the payment of all or part of the
          purchase price of property or to secure any Debt incurred prior to, at
          the time of or within 180 days after the acquisition of such property
          for the purpose of financing all or part of the purchase price of such
          property;

               (d)  mortgages existing as of the Substitution Date;

               (e)  Permitted Encumbrances (as defined below);

               (f)  any extension, refinancing, renewal or replacement (or
          successive extensions, refinancings, renewals or replacements), in
          whole or in part, of any mortgage referred to in clauses (a) through
          (e); provided, however, that the principal amount of Debt secured
          thereby may not exceed the principal amount of Debt (plus any premium
          or fee payable in connection with such extension, renewal or
          replacement) so secured at the time of such extension, refinancing,
          renewal or replacement; and provided, further, that such mortgage must
          be limited to all or such part of the property which was subject to
          the mortgage so extended, refinanced, renewed or replaced (plus
          improvements on such property);

               (g)  mortgages in favor of the United States, any State thereof,
          any other country or any political subdivision of any of the
          foregoing, to secure partial, progress, advance or other payments
          under any contract or statute; or

               (h)  mortgages securing industrial development, pollution control
          or similar revenue bonds.

     Notwithstanding the foregoing restriction, the Company may create, assume
or incur any mortgage not excepted above without equally and ratably securing
the Notes if the aggregate amount of all Debt then outstanding and secured by
such mortgage or any other mortgage not excepted above does not exceed 10% of
the total 

                                      -7-
<PAGE>
 
consolidated capitalization of the Company as shown on the audited consolidated
balance sheet contained in the latest annual report of the Company as filed with
the Commission. For the purposes of this provision, any mortgage in favor of the
United States of America or any States thereof, or any other country, or any
political subdivision of any of the foregoing, to secure partial, progress,
advance or other payments pursuant to the provisions of any contract or statute,
or any mortgage securing industrial development, pollution control or similar
revenue bonds shall not be deemed to create a mortgage to secure any Debt.

     For the purposes of this provision, the term "Permitted Encumbrance" means

          (a)  Liens for taxes, assessments or governmental charges or levies
for the then current year and taxes, assessments or governmental charges or
levies not then delinquent or which thereafter can be paid without penalty or
are being contested in good faith; liens for worker's compensation awards and
similar obligations not then delinquent or which thereafter can be paid without
penalty or are being contested in good faith; liens imposed by law, such as
carriers', warehousemen's, landlords', suppliers', mechanics', laborers',
materialmen's and other similar liens not then delinquent or which are being
contested in good faith;

          (b)  Liens and charges incidental to construction or current operation
which have not at such time been filed or asserted or the payment of which has
been adequately secured or which are insignificant in amount;

          (c)  Liens securing obligations not assumed by the Company and on
account of which it has not customarily paid and does not expect to pay interest
and existing upon real estate over or in respect of which the Company has a
right of way or other easement or right for pipelines, rights of way,
transmission, distribution or similar purposes; provided that the loss of all
such easements would not materially adversely affect the operations of the
Company;

          (d)  Any right which the United States of America or any municipal or
governmental body or agency may have by virtue of any franchise, license,
contract or statute to recapture or to purchase, or designate a purchaser of or
order the sale of, any property of the Company upon payment of reasonable
compensation therefor, or upon reasonable compensation or conditions to
terminate any franchise, license or other rights before the expiration date
thereof or to regulate the property and business of the Company;

          (e)  Liens of judgments covered by insurance, or upon appeal or other
proceeding for review, or not exceeding at any one time $10 million in aggregate
amount;

          (f)  Easements or reservations in respect of any property of the
Company for the purpose of transmission or distribution lines or other rights-
of-way, including overhead and underground transmission and distribution lines
and pipelines, or similar purposes, zoning ordinances, regulations,
reservations, survey exceptions, building restrictions, covenants, party wall
agreements, conditions of records and such other encumbrances or charges against
real property as are of a nature generally existing with respect to properties
of a similar character;

          (g)  Liens on the property of the Company incurred in the ordinary
course of business to secure performance of obligations with respect to
statutory or regulatory requirements, performance  or return-of-money bonds,
surety bonds or other obligations of a like nature, in each case which are not
incurred in connection with the borrowing of money, the obtaining of advances or
credit or the payment of the deferred purchase price of property;

          (h)  Pledges or deposits by the Company under workmen's compensation
laws, unemployment insurance laws or similar legislation, or good faith deposits
in connection with bids, tenders, contracts (other than for the payment of Debt)
or leases to which the Company is a party, or deposits to secure public or
statutory obligations of the Company, or deposits of cash or United States
government bonds to secure surety or appeals bonds obtained in the ordinary
course of business to which the Company is a party, or deposits as security for
taxes (that shall not at the time be delinquent or thereafter can be paid
without penalty or are being 

                                      -8-
<PAGE>
 
contested in good faith) or import duties incurred in the ordinary course of
business, or deposits for the payment of rent or performance of other
obligations under a lease, in each case incurred in the ordinary course of
business;

          (i)  Rights reserved to or vested in any municipality or public
authority by the terms of any franchise, grant, license, or governmental consent
or permit, or by any provision of law, to acquire, purchase, or recapture at
fair value, or to designate a purchaser of such property;

          (j)  Rights reserved to or vested in any municipality or public
authority to use or control or regulate such property;

          (k)  Any obligations or duties, affecting such property, to any
municipality or public authority with respect to any franchise, grant, license
or permit;

          (l)  Exceptions or reservations therefrom of minerals, precious

exceptions or reservations exist at the time of acquisition by the Company of
the property and which do not materially and adversely affect the use made or
proposed to be made by it of such property; or

          (m)  Liens existing on the Substitution Date not otherwise described
in clauses (a) through (l) above.

REDEMPTION

     The Pricing Supplement relating to each Note will indicate that such Note
cannot be redeemed prior to its stated maturity or that such Note will be
redeemable at the option of the Company in whole or in part, on any date on or
after the date specified in such Pricing Supplement, at prices declining from a
specified premium, if any, to par, together with accrued interest to the date of
redemption.  In addition, the Notes shall be subject to redemption upon payment
of the principal amount thereof, either as a whole or in part, from time to
time, through the application of proceeds available under the Mortgage upon
redemption of the Pledged Bond from the condemnation of property subject to the
lien of the Mortgage, or proceeds of sale of such property to a governmental
body or agency having the power of eminent domain made as a result of the threat
(evidenced in writing by such body or agency) of condemnation of such property
together with accrued interest to the date fixed for redemption in accordance
with the terms of the Mortgage. See "Description of the Pledged Bond--
Redemption"


EVENTS OF DEFAULT

     The following constitute events of default under the Note Indenture:

          (a)  default in the payment of principal or premium, if any, on any
     Note when due and payable and continuance of such default for five days;

          (b)  default in the payment of interest on any Note when due which
     continues for 30 days;

          (c)  default in the performance or breach of any other covenant or
     warranty of the Company in the Note Indenture and the continuation thereof
     for 90 days after written notice to the Company as provided in the Note
     Indenture;

          (d)  prior to the Substitution Date, the occurrence of a default under
     the Mortgage, of which default the Mortgage Trustee or the holders of a
     majority in aggregate principal amount of the outstanding Notes have given
     written notice to the Note Trustee;

          (e)  if any Substituted Pledged Bonds are outstanding, the occurrence
     of a default under the Substituted Mortgage, of which default the trustee
     under such Substituted Mortgage or the holders of a majority in aggregate
     principal amount of the outstanding Notes have given written notice to the
     Note Trustee; and

                                      -9-
<PAGE>
 
               (f)  certain events of bankruptcy, insolvency or reorganization
          of the Company. (Section 8.1).

     If an Event of Default, other than one relating to an event of default
under the Mortgage or the Substituted Mortgage, as applicable, and the
acceleration of the principal of the First Mortgage Bonds or any Substituted
Pledged Bonds in accordance with the Mortgage or the Substituted Mortgage, as
applicable, occurs and is continuing, either the Note Trustee or the registered
holders of a majority in aggregate principal amount of the outstanding Notes of
such series may declare the principal amount of all Notes of such series to be
due and payable immediately. At any time after an acceleration of the Notes of
such series has been declared, but before a judgment or decree for the immediate
payment of the principal amount of such Notes has been obtained and so long as
all of the Company's first mortgage bonds have not been accelerated, the
registered holders of a majority in aggregate principal amount of the
outstanding Notes of such series may, under certain circumstances, rescind and
annul such acceleration and its consequences. If an Event of Default relating to
an event of default under the Mortgage or the Substituted Mortgage, as
applicable, and the acceleration of the principal of the first mortgage bonds
issued under either the Mortgage or the Substituted Mortgage, as the case may
be, in accordance with the Mortgage or the Substituted Mortgage, as applicable,
occurs (see "Description of the Pledged Bond--Defaults and Notice Thereof"), the
principal of all of the Notes, together with interest accrued thereon, shall
become due and payable immediately without the necessity of any action by the
Note Trustee or the registered holders of any Notes; provided, however, that a
rescission and annulment of the declaration that the Company's first mortgage
bonds outstanding under the Mortgage or the Substituted Mortgage, as applicable,
be due and payable prior to their stated maturities shall constitute a waiver of
such Event of Default under the Note Indenture and of its consequences (Section
8.1).

     The Note Indenture provides that the Note Trustee generally will be under
no obligation to exercise any of its rights or powers under the Note Indenture
at the request or direction of any of the holders unless such holders have
offered to the Note Trustee reasonable security or indemnity against the
liabilities and costs which may be incurred by such exercise. (Section 9.2). The
holders of a majority in principal amount of the outstanding Notes generally
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Note Trustee, or of exercising any
trust or power conferred on the Note Trustee, with respect to the Notes.
(Section 8.7). Each holder of any Note has the right to institute a proceeding
with respect to the Note Indenture, but such right is subject to certain
conditions precedent specified in the Note Indenture. (Section 8.4). The Note
Indenture provides that the Note Trustee, within 90 days after the occurrence of
a default with respect to the Notes, is required to give the holders of the
Notes notice of such default, unless cured or waived, but, except in the case of
default in the payment of principal of, or premium, if any, or interest on any
Notes, the Note Trustee may withhold such notice if it determines in good faith
that it is in the interest of such holders to do so. (Section 8.8). The Company
is required to deliver to the Note Trustee each year a certificate as to whether
or not, to the knowledge of the officers signing such certificate, the Company
is in compliance with the conditions and covenants under the Note Indenture
(Section 6.6).

MODIFICATION

     Modification and amendment of the Note Indenture may be effected by the
Company and the Note Trustee with the consent of the holders of a majority in
principal amount of the outstanding Notes affected thereby, provided that no
such modification or amendment may, without the consent of the holder of each
outstanding Note affected thereby, (a) change the maturity date of any Note; (b)
reduce the rate or extend the time of payment of interest on any Note; (c)
reduce the principal amount of, or premium payable on, any Note; (d) change the
coin or currency of any payment of principal of, or any premium or interest on,
any Note; (e) change the date on which any Note may be redeemed or adversely
affect the rights of a holder to institute suit for the enforcement of any
payment on or with respect to any Note; (f) impair the interest of the Note
Trustee in the Pledged Bond or Substituted Pledged Bonds held by it or, prior to
the Substitution Date, reduce the principal amount of the Pledged Bond or
Substituted Pledged Bonds securing the Notes to an amount less than the
principal amount of the related issue of Notes or alter the payment provisions
of such Pledged Bond or Substituted Pledged Bonds in a manner adverse to the
holders of the Notes; or (g) modify the foregoing requirements or reduce the
percentage of outstanding Notes necessary to modify or amend the Note Indenture
or to waive any past default to less than a majority. Modification and amendment
of the Note Indenture may be effected by the Company and the Note Trustee
without the consent 

                                      -10-
<PAGE>
 
of the holders (a) to add to the covenants of the Company for the benefit of the
holders or to surrender a right conferred on the Company in the Note Indenture;
(b) to add further security for the Notes; (c) to make certain other
modifications, generally of a ministerial or immaterial nature; or (d) to make
certain other modifications which are not prejudicial to the interests of the
holders of the Notes (Sections 13.1 and 13.2).

DEFEASANCE AND DISCHARGE

     The Note Indenture provides that the Company will be discharged from any
and all obligations in respect to the Notes and the Note Indenture (except for
certain obligations such as obligations to register the transfer or exchange of
Notes, replace stolen, lost or mutilated Notes and maintain paying agencies) if,
among other things, the Company irrevocably deposits with the Note Trustee, in
trust for the benefit of holders of Notes, money or certain United States
government obligations, or any combination thereof, which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money in an amount sufficient, without reinvestment, to make all
payments of principal of, and any premium and interest on, the Notes on the
dates such payments are due in accordance with the terms of the Note Indenture
and the Notes. Thereafter, the holders of Notes must look only to such deposit
for payment of the principal of, and interest and any premium on, the Notes
(Section 5.1).

CONSOLIDATION, MERGER AND SALE OR DISPOSITION OF ASSETS

     The Company will not consolidate with or merge into any other corporation
or sell, transfer or otherwise dispose of all or substantially all its assets
unless the successor or transferee corporation assumes by supplemental indenture
the due and punctual payment of the principal of and premium and interest on all
the Notes and the performance of every covenant of the Note Indenture to be
performed or observed by the Company and (i) if such transaction occurs prior to
the Substitution Date, unless the successor or transferee corporation assumes
the Company's obligations under the Mortgage with respect to the Pledged Bond,
or (ii) if such transaction occurs on or after the Substitution Date and
Substituted Pledged Bonds are outstanding, unless the successor or transferee
corporation assumes the Company's obligations under the Substituted Mortgage
with respect to the Substituted Pledged Bonds. Upon any such consolidation,
merger, sale, transfer or other disposition of all or substantially all of the
assets of the Company, the successor corporation formed by such consolidation or
into which the Company is merged or to which such transfer is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under the Note Indenture with the same effect as if such successor
corporation had been named as the Company therein and the Company will be
released from all obligations under the Note Indenture. The Note Indenture
defines "all or substantially all" of the assets of the Company as being 50% or
more of the total assets of the Company as shown on the balance sheet of the
Company as of the end of the prior year and specifically permits any such sale,
transfer or other disposition during a calendar year of less than 50% of total
assets without the consent of the holders of the Notes and without the
assumption by the transferee of the Company's obligations on the Notes and
covenants contained in the Note Indenture. (Sections 12.1 and 12.2).

VOTING OF THE PLEDGED BOND HELD BY NOTE TRUSTEE

     The Note Trustee, as a holder of the Pledged Bond, may attend any meeting
of bondholders under the Mortgage to which it receives due notice, or, at its
option, may deliver its proxy in connection therewith. Either at such meeting,
or where any action, amendment, modification, waiver or consent to or in respect
of the Mortgage or Bonds issued under the Mortgage is sought without a meeting
(a "proposed action"), the Note Trustee will vote the Pledged Bond held by it,
or will consent with respect thereto, as described below. The Note Trustee may
agree to any proposed action without the consent of or notice to holders of the
Notes where such proposed action would not adversely affect the holders of the
Notes. In the event that the proposed action would adversely affect the holders
of the Notes, the Note Trustee shall not vote the Pledged Bond without notice to
and the approval of holders of at least a majority in aggregate principal amount
of Notes then outstanding. (Section 4.3).

                                      -11-
<PAGE>
 
RESIGNATION OR REMOVAL OF NOTE TRUSTEE

     The Note Trustee may resign at any time upon written notice to the Company
specifying the day upon which the resignation is to take effect and such
resignation will take effect immediately upon the later of the appointment of a
successor Note Trustee and such specified day. (Section 9.10).

     The Note Trustee may be removed at any time by an instrument or concurrent
instruments in writing filed with the Note Trustee and signed by the holders, or
their attorneys-in-fact, of at least a majority in principal amount of the then
outstanding Notes. In addition, so long as no event of default or event which,
with the giving of notice or lapse of time or both, would become an event of
default has occurred and is continuing, the Company may remove the Note Trustee
upon notice to the holder of each Note outstanding and the Note Trustee, and
appointment of a successor Note Trustee (Section 9.10).

BOOK-ENTRY SYSTEM

     Each issue of Notes may be issued in the form of one or more Global Notes
representing all or part of such issue of Notes and which will be deposited with
or on behalf of the Depository and registered in the name of the Depository or a
nominee of the Depository.

     The following is based solely on information furnished by the Depository:

     Unless otherwise specified in the Pricing Supplement, DTC will act as
Depository for those Notes issued as Global Notes. The Global Notes will be
issued as fully-registered securities registered in the name of Cede & Co.
(DTC's partnership nominee). DTC is a limited-purpose trust company organized
under the New York Banking Law, a "banking organization" within the meaning of
the New York Banking Law, a member of the Federal Reserve System, a "clearing
corporation" within the meaning of the New York Uniform Commercial Code, and a
"clearing agency" registered pursuant to the provisions of Section 17A of the
Securities Exchange Act of 1934. DTC holds securities that its participants
("Participants") deposit with DTC. DTC also facilitates the settlement among
Participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in
Participants' accounts, thereby eliminating the need for physical movement of
securities certificates. "Direct Participants" include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations. DTC is owned by a number of its Direct Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks, and
trust companies that clear through or maintain a custodial relationship with a
Direct Participant, either directly or indirectly ("Indirect Participants"). The
rules applicable to DTC and its Participants are on file with the Commission.

     Purchases of the Notes under the DTC system must be made by or through
Direct Participants, which will receive a credit for the Notes on DTC's records.
The ownership interest of each actual purchaser of each Note ("Beneficial
Owner") is in turn to be recorded on the Direct and Indirect Participants'
records. Beneficial Owners will not receive written confirmation from DTC of
their purchase, but Beneficial Owners are expected to receive written
confirmation providing details of the transaction, as well as periodic
statements of their holdings, from the Direct or Indirect Participant through
which the Beneficial Owner entered into the transaction. Transfers of ownership
interests in the Notes are to be accomplished by entries made on the books of
Participants acting on behalf of Beneficial Owners. Beneficial Owners will not
receive certificates representing their ownership interests in the Notes, except
in the event that use of the book-entry system for the Notes is discontinued.

     To facilitate subsequent transfers, all securities deposited by
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of the Notes with DTC and their registration in the name
of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of
the actual Beneficial Owners of the Notes; DTC's records reflect only the
identity of the Direct Participants to whose accounts such Notes are credited,
which may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of the holdings on behalf of their customers.

                                      -12-

     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants to Beneficial Owners will be governed by arrangements among them,
subject to any statutory or regulatory requirements as may be in effect from
time to time.

     If the Global Notes are redeemable, redemption notices shall be sent to
Cede & Co. If less than all of the Global Notes are being redeemed, DTC's
practice is to determine by lot the amount of the interest of each Direct
Participant in such issue to be redeemed.

     Neither DTC nor Cede & Co. will consent or vote with respect to the Notes.
Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as
possible after the record date. The Omnibus Proxy assigns Cede & Co.'s
consenting or voting rights to those Direct Participants to whose accounts the
Notes are credited on the record date (identified in a listing attached to the
Omnibus Proxy).

     Principal, interest and any premium payments on the Notes will be made to
DTC. DTC's practice is to credit Direct Participant's accounts on payable date
in accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payment on payable date. Payments
by Participants to Beneficial Owners will be governed by standing instructions
and customary practices, as in the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such Participant and not of DTC, the applicable Trustee or the
Company, subject to any statutory or regulatory requirements as may be in effect
from time to time. Payment of principal, interest and any premium to DTC is the
responsibility of the Company or the applicable Trustee, disbursement of such
payments to Direct Participants shall be the responsibility of DTC, and
disbursement of such payments to the Beneficial Owners shall be the
responsibility of Direct and Indirect Participants.

     DTC may discontinue providing its services as securities depository with
respect to a series of Notes at any time by giving reasonable notice to the
Company or the Note Trustee. Under such circumstances, if a successor securities
depository is not obtained, certificates for such series of Notes are required
to be printed and delivered.

     The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository) for any series of
Notes. In that event, certificates for such series of Notes will be printed and
delivered.

     The information in this section concerning DTC and DTC's book-entry system
has been obtained from DTC, and the Company and any underwriters, dealers or
agents take no responsibility for the accuracy thereof.

     The underwriters, dealers or agents of any Notes may be Direct Participants
of DTC.

     NONE OF THE COMPANY, THE NOTE TRUSTEE, THE MORTGAGE TRUSTEE, OR ANY AGENT
FOR PAYMENT ON OR REGISTRATION OF TRANSFER OR EXCHANGE OF THE GLOBAL NOTE WILL
HAVE ANY RESPONSIBILITY OR LIABILITY FOR ANY ASPECT OF THE RECORDS RELATING TO
OR PAYMENTS MADE ON ACCOUNT OF BENEFICIAL INTERESTS IN SUCH GLOBAL NOTE OR FOR
MAINTAINING, SUPERVISING OR REVIEWING ANY RECORDS RELATING TO SUCH BENEFICIAL
INTERESTS.

CONCERNING THE NOTE TRUSTEE

     The Bank of New York is the Note Trustee under the Note Indenture. The Note
Trustee also acts as trustee for the Company's first mortgage bonds. The Company
also currently maintains other banking relationships with the Note Trustee in
the ordinary course of business.


                        DESCRIPTION OF THE PLEDGED BOND

GENERAL

     The Pledged Bond is to be issued under and secured by the Mortgage and the
New Supplement providing for the Pledged Bond. The Pledged Bond constitutes the
series of the Company's First Mortgage Bonds designated as South Jersey Gas
Company First Mortgage Bonds, 10% Medium Term Notes Series A, which is limited
to the aggregate principal amount of $100,000,000. The following statement
includes brief summaries of certain provisions of the Mortgage. For a complete
statement of such provisions, reference is made to the actual provisions

                                      -13-
<PAGE>
 
of the Mortgage. First Mortgage Bonds issued or issuable under the Mortgage are
hereinafter sometimes called "Bonds." A copy of the Mortgage including a
proposed New Supplement may be inspected at the office of the Mortgage Trustee
at 101 Barclay Street, Floor 21 West, New York, New York 10286 or at the office
of the Commission, 450 Fifth Street, N.W., Washington, D.C. References to
articles and sections under this caption are reference to articles and sections
of the Mortgage.

     The Pledged Bond will be issued initially to the Note Trustee and will be
issuable only in fully registered form in any denomination authorized by the
Company. The Pledged Bond will be transferable and the several denominations
thereof will be exchangeable for Bonds of other authorized denominations but of
the same series and aggregate principal amount, upon compliance with the
applicable provisions of the Mortgage and the Note Indenture. No service charge
will be made for any such transfer or exchange, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto.

     The Pledged Bond has not been registered under the Securities Act of 1933,
as amended.

INTEREST, MATURITY AND PAYMENT

     Interest on the Pledged Bond shall accrue at the rate of 10% per annum
computed on the basis of a 360-day year of twelve 30-day months and shall be
payable semi-annually in arrears on May 1 and November 1 of each year, payable
initially on May 1, 1999, subject to receipt of certain credits against
principal and interest and such obligations as set forth below.

     In addition to any other credit, payment or satisfaction to which the
Company is entitled with respect to the Pledged Bond, the Company shall be
entitled to credits against amounts otherwise payable in respect of the Pledged
Bond in an amount corresponding to (i) the principal amount of any of the Notes
issued under the Note Indenture secured thereby surrendered to the Note Trustee
by the Company, or purchased by the Note Trustee, for cancellation, (ii) the
amount of money held by the Note Trustee and available and designated for the
payment of principal of, and/or interest on, the Notes secured thereby,
regardless of the source of payment to the Note Trustee of such moneys and (iii)
the amount by which principal of and interest due on the Pledged Bond exceeds
principal of and interest due on the Notes secured thereby. The Note Trustee
shall make notation on the Pledged Bond of any such credit.

LIEN AND SECURITY

     The Pledged Bond is secured by the lien of the Mortgage equally and
proportionately with all other Bonds. The Mortgage constitutes a first lien
(subject to "excepted encumbrances" as defined in the Mortgage) on substantially
all the property and franchises of the Company now owned or hereafter acquired,
for the equal and ratable benefit of all Bonds now or hereafter outstanding
under the Mortgage. The Mortgage excepts from its lien materials and supplies
consumable in the operation of the Company, merchandise and products acquired,
manufactured, produced or held for sale in the usual course of business, motor
vehicles, and cash, accounts receivable, stocks, bonds, notes, and securities
which are neither specifically pledged with the Mortgage Trustee nor required by
the Mortgage to be so pledged (Granting Clause). There are certain conditions
which must be complied with relating to the lien of the Mortgage in case of a
merger, consolidation or sale of all the assets of the Company. (Article VII)

ISSUANCE OF ADDITIONAL BONDS

     Additional Bonds, ranking equally with all outstanding Bonds, may be issued
under the Mortgage, without limit as to aggregate principal amount, upon
compliance with Article III of the Mortgage and after obtaining the approval of
the New Jersey Board of Public Utilities ("BPU"). The principal provisions for
the issuance of additional Bonds are summarized below.

     Additional Bonds may be issued in principal amount not exceeding: (i) 60%
of the cost or fair value (whichever is less) of property additions which
consist of real and personal property constructed or acquired by the Company
subject to the lien of the Mortgage and not previously utilized under the
Mortgage as the basis for additional bonds or certain other purposes, located in
the State of New Jersey, and used or useful by the Company in connection with
its business, after deducting from such cost or fair value the excess, if any,
of the cost of

                                      -14-
<PAGE>
 
mortgaged property retired (as defined in the Mortgage) and certain amounts
relating to depreciation of the mortgaged property which are calculated in the
annual certificate for the replacement fund hereafter referred to; provided
that:  (a) the net earnings of the Company (as defined in the Mortgage) for 12
consecutive months within the preceding 15 months shall have been at least 2
times the annual interest charges on all prior lien obligations and all Bonds to
be outstanding after the authentication of those about to be authenticated; and
(b) if such property additions are subject to a prior lien:  (x) 166-2/3% of the
principal amount of the outstanding obligations secured by such prior lien shall
be deducted from the cost or fair value of such property additions (unless such
deduction has been made previously); and (y) if the deduction referred to in
clause (x) has not previously been made, then the aggregate principal amount of
all outstanding prior lien obligations upon all property additions used as the
basis for authentication of Bonds, withdrawal of money, or release of property
under the Mortgage or as a credit against a payment to any improvement or
sinking fund for Bonds of a particular series, or the replacement fund
hereinafter referred to, shall not exceed 10% of the principal amount of all
Bonds to be outstanding after authentication of those about to be authenticated
(Section 3.04); (ii) the principal amount of other Bonds acquired, paid,
retired, or with respect to which payment has been provided for excluding,
however, any such Bonds paid or retired by the operation of any sinking,
replacement, purchase or other analogous fund or otherwise used as a credit
against the obligations of the Company, with certain specified exceptions;
provided that if such Bonds were not theretofore bona-fide issued and bear
interest at a lower rate than the Bonds to be authenticated, the net earnings
condition specified above in paragraph (i) must be complied with (Sections 3.04
and 3.06); and (iii) the amount of money deposited with the Mortgage Trustee for
that purpose (Sections 3.03 and 3.07). Money so deposited may be withdrawn by
the Company upon the same conditions as would entitle it to obtain the
authentication of Bonds of an equal principal amount under the above clauses (i)
or (ii), except that if the net earnings condition specified in clause (i) was
complied with at the time of the deposit of such money and included all interest
charges on prior lien obligations existing at the time of the requested
withdrawal, it need not be again complied with upon the withdrawal thereof.
Pending such withdrawal, such money may be invested by the Mortgage Trustee in
obligations of the United States and the net proceeds of any sale thereof
withdrawn as aforesaid (Section 3.08 and 3.09).

     If the additional Bonds are to be issued on the basis of property
additions, the Mortgage requires the delivery to the Mortgage Trustee of a
certificate of an engineer, appraiser, or other expert as to the fair value of
such additions to the Company as of a specified date not more than three months
before the application for the additional Bonds is filed with the Mortgage
Trustee. If any of such additions were acquired from another gas utility, the
Mortgage requires that the initial appraisal be performed by an engineer,
appraiser or other expert who is independent of the Company (Section 3.04, as
amended by 17/th/ Supp.).

REPLACEMENT FUND

     The Mortgage requires that the Company on or before April 1 of each year,
deliver a replacement fund certificate and pay to the Mortgage Trustee for a
replacement fund an amount equal to $198,000 plus 2% of the cost of all
additions made to its depreciable public utility property during the period from
0ctober 1, 1947, to the end of the preceding calendar year, less 2% of the cost
of all depreciable public utility property retired by it during such period. The
Company may take as a credit against such payment (a) 166-2/3% times the
principal amount of bonds which could then be issued on the basis of property
additions, and (b) the principal amount of Bonds paid, acquired, or retired by
it, to the extent that the same have not been otherwise included in a prior
Replacement Fund Certificate filed with the Mortgage Trustee. So long as any
Bonds of the Fourteenth Series, Fifteenth Series, Sixteenth Series, Seventeenth
Series, Eighteenth Series, Nineteenth or Twentieth Series remain outstanding,
the Company will satisfy its obligations under the replacement fund through the
use of cash only if it has first used all available property additions and
retired bonds, and then only to the extent such amounts are not sufficient to
satisfy such obligations. All money in the replacement fund shall, upon request
by the Company, be applied as described below under "Release and Substitution of
Property" in the case of proceeds from the sale of released property (Sections
5.19 and 6.07; 15/th/ Supp., Section 3.2; 16th Supp., Section 3.2; 18th Supp.,
Section 3.2.; 19th Supp., Section 3.2.; 20th Supp., Section 3.2; 21/st/
Supp., Section 3.2; and 22/nd/ Supp. Section 3.2).

                                      -15-
<PAGE>
 
RELEASE AND SUBSTITUTION OF PROPERTY

     Upon substitution of other property of equal value, the Company may dispose
of, free from the lien of the Mortgage and without procuring a release
therefrom, any machinery, tools, implements, fixtures, or equipment unsuitable
or not required for the conduct of its business (Section 6.03). Any property no
longer necessary for the proper conduct of its business may be sold, exchanged
or disposed of by the Company, and released from the lien of the Mortgage, upon
receipt by the Company of a consideration, which shall be paid or delivered to
the Mortgage Trustee (unless required to be paid or delivered to the trustee of
a prior lien), equal to at least the fair value thereof and which shall consist
of (i) money, (ii) obligations of any federal, state, municipal, or other
governmental body or agency purchasing such property, (iii) obligations maturing
within 15 years, secured by a purchase money mortgage on such property, and
constituting not more than 60% of such consideration, and/or (iv) property
additions (not otherwise utilized under the Mortgage) which might have formed
the basis for the authentication of additional Bonds (Sections 6.04 and 6.05).
Property taken by eminent domain proceedings or under governmental power of
purchase shall be released from the Mortgage and the proceeds of such taking or
purchase shall be paid to the Trustee (Section 6.08). Proceeds received by the
condemnation or from the sale of property released from the Mortgage (i) may be
withdrawn by the Company upon compliance with the same conditions that would
authorize the authentication of Bonds of an equal principal amount, except that
no earnings condition shall be applicable, and except that money may be
withdrawn on the basis of property additions up to 100% of the cost or fair
value (whichever is less) thereof after deducting the required amount on account
of any prior lien obligations and without any deduction for the cost of property
retired; (ii) may be temporarily invested by the Mortgage Trustee in obligations
of the United States; or (iii) may be applied to the purchase or redemption of
Bonds; provided that all such proceeds (including proceeds temporarily invested
as aforesaid) not withdrawn or applied for 5 years after receipt by the Mortgage
Trustee shall be applied to the purchase or redemption of Bonds (Section 6.07).
Proceeds of insurance on mortgaged property, except on losses of less than
$10,000, are payable to the Mortgage Trustee and may be applied by it (i) to
reimburse the Company for the cost of repairing, renewing, or replacing property
damaged or destroyed or (ii) as above provided in the case of proceeds of the
sale of property released from the Mortgage (Section 5.12). No prior notice is
required in connection with any releases or substitutions of property, but
Section 8.03 contains provisions relating to the transmission by the Mortgage
Trustee to Bondholders, from time to time, of reports of such releases or
substitutions, and the consideration received therefor.

RESTRICTIONS ON DIVIDENDS

     So long as any Bonds of the Twentieth Series shall remain outstanding, the
Company will not declare or pay any dividend on any shares of its Common Stock
(other than dividends payable in shares of its Common Stock) or make any
distribution on such shares, or purchase or otherwise acquire any such shares
(except shares acquired without cost to the Company), or advance any amount to
or invest any amount in the property, securities or indebtedness of, or
guarantee any indebtedness of, any subsidiary if, after giving effect to such
action, the sum of the aggregate amounts so declared, paid, distributed,
purchased, acquired, advanced, invested or guaranteed after December 31, 1997
would exceed the aggregate net income of the Company available for dividends on
its Common Stock earned after such date plus the sum of $56,000,000. (Section
3.1; 22/nd/ Supp.)  For the purposes of this restriction, "subsidiary" shall
mean any corporation directly or indirectly controlled by or under common
control with the Company. For the purpose of calculating the requirements of
this restriction, the net income of the Company available for dividends on its
Common Stock shall be determined in accordance with such system of accounts as
may be prescribed by any governmental authority having jurisdiction in the
premises or in the absence thereof in accordance with generally accepted
accounting principles as in effect at such time; provided, however, that (a) the
deductions for depreciation or renewal or replacement reserves in respect of
each year shall be the amount taken therefor on the accounts of the Company or
the amount required to be stated in item (1) of the Replacement Fund Certificate
to be filed under the Mortgage with respect to the period ending at the close of
such year, whichever be greater, and (b) no deduction or adjustment shall be
made from gross income for or in respect of (i) expenses in connection with the
redemption or retirement of any securities issued by the Company, including any
amount paid in excess of the principal or par or stated value of securities
redeemed or retired, and, if such redemption or retirement is effected with the
proceeds of sale of other securities of the Company, interest on the securities
redeemed or retired from the date on which the funds required for such
redemption or retirement shall be deposited in trust for such purpose to the
date of such redemption or retirement, (ii) profits or losses from sales of

                                      -16-
<PAGE>
 
capital assets or taxes in respect of such profits, (iii) any adjustments to
retained earnings (including tax adjustments) applicable to any period prior to
January 1, 1998, (iv) charges for the write-off of unamortized debt discount and
expense carried on the books of the Company at December 31, 1997, or (v) charges
for the write-off or write-down of the amount at which any property of the
Company was carried on its books at December 31, 1997, to the extent that the
same shall be approved by, or be made pursuant to any rule, regulation, or order
of, any governmental authority having jurisdiction in the premises and shall not
be required by such authority to be charged against earning accumulated after
December 31, 1997. (Section 3.1; 22/nd/ Supp.)

REDEMPTION

     Bonds of the Twentieth Series, including the Pledged Bond, shall be subject
to redemption, either as a whole or in part, from time to time upon payment of
the principal amount thereof through the application of proceeds available under
the Mortgage from the condemnation of property subject to the lien of the
Mortgage, or proceeds of sale of such property to a governmental body or agency
having the power of eminent domain made as a result of the threat (evidenced in
writing by such body or agency) of condemnation of such property together with
accrued interest to the date fixed for redemption in accordance with the terms
of the Mortgage, which provides that if less than all Bonds of all Series are
redeemed then proceeds from the sale of such property will be applied to the
redemption of all Bonds, including the Pledged Bond, on a pro rata basis, based
on the amount of the Bonds then outstanding. (Section 1.7, 22/nd/ Supp.)

CONSOLIDATION, MERGER, OR SALE

     Subject to the approval of the BPU, the Mortgage does not prevent a
consolidation or merger of the Company with or into any other corporation or a
conveyance and transfer of all of the property and franchises of the Company to
any other corporation, if (i) the consolidation, merger, or conveyance and
transfer is subject to the continuing lien of the Mortgage on the mortgaged
property and will not impair the lien or any of the rights or powers of the
Trustee or Bondholders; (ii) the corporation formed by the consolidation or into
which the Company is merged or which acquires the mortgaged property assumes and
agrees in writing to pay the Bondholders the principal of and interest on all
the Bonds, as and when due; (iii) any such successor corporation executes and
delivers a supplemental indenture which contains, among other things:  (w) an
agreement to perform all obligations of the Company under the Mortgage, (x) a
stipulation that such consolidation, merger, or conveyance and transfer is not a
waiver or release of any rights or powers of the Mortgage Trustee or the
Bondholders, (y) a grant confirming the lien of the Mortgage Trustee upon the
mortgaged property and (z) a grant to the Mortgage Trustee subjecting to the
lien of the Mortgage property additions to be used in the future and certain
after-acquired property; and (iv) the Mortgage Trustee shall have consented to
the consolidation, merger, or conveyance and transfer, which consent the
Mortgage Trustee is required to give upon receiving an opinion of counsel that
the foregoing conditions in the Mortgage have been satisfied unless in the
Mortgage Trustee's opinion the transaction would be prejudicial to the interests
of the bondholders.  (Section 7.01)

MODIFICATIONS OF MORTGAGE

     With the written consent of the holders of 66-2/3% in principal amount of
the Bonds outstanding, any of the provisions of the Mortgage or of the Bonds may
be altered, amended or eliminated, or additional provisions added. If such
change pertains only to the Bonds of one or more Series, but less than all
Series, only the written consent of the holders of 66-2/3% in principal amount
of the then outstanding Bonds of each Series to which such change pertains is
needed. However, no such change may (i) alter or modify the right (expressed in
Section 9.16) of any Bondholder to receive payment of the principal of and
interest on his Bonds on or after the respective due dates thereof; (ii) change
any of the provisions of any Bond with respect to the time, terms, manner, or
amount of any payment of the principal thereof or interest thereon without the
consent of the holder of such Bonds; or (iii) reduce the percentage of
Bondholders whose consent shall be required for the execution of any subsequent
supplemental indenture. The consent of the BPU may be required before certain of
the above actions may be taken (Section 10.02). Certain other modifications and
amendments described in the Mortgage may be made without the consent of the
Bondholders (Section 10.01).

                                      -17-
<PAGE>
 
PERCENTAGE OF BONDHOLDERS REQUIRED TO TAKE CERTAIN ACTION

     Upon the occurrence of a Mortgage Event of Default (as defined below), the
Mortgage Trustee or the holders of 25% in principal amount of the Bonds then
outstanding may by written declaration accelerate the maturity of the principal
of all the Bonds (Section 9.03); but if the Company shall cure all Mortgage
Events of Default, the holders of a majority in principal amount of the Bonds
then outstanding may rescind, or require the Mortgage Trustee to rescind, such
acceleration (Section 9.13). The holders of 66-2/3% in principal amount of the
Bonds then outstanding may waive any past default under the Mortgage and its
consequences except a default in the payment of principal of or interest on any
of the Bonds (Section 9.13). No bondholder may enforce the lien of the Mortgage
unless the holders of 25% in principal amount of the Bonds then outstanding have
requested the Mortgage Trustee to do so and offered to indemnify it against
expenses and liabilities in connection therewith, and unless the Mortgage
Trustee has failed to take such action within 60 days (Section 9.15). The
holders of a majority in principal amount of the Bonds then outstanding may
direct the time, method and place of conducting any proceeding for any remedy
available to the Mortgage Trustee or exercising any trust or power conferred on
it, unless such action would be contrary to law or the provisions of the
Mortgage or would, in the opinion of the Mortgage Trustee, be unjustly
prejudicial to the other Bondholders (Section 9.18).

     For the purpose of computing the percentage of holders of Bonds requisite
for the taking of any action permitted under the Mortgage (including the
modification of the Mortgage) the calculation will be on the basis of the
principal amount of all Bonds outstanding exclusive of Bonds held by the Company
and all Bonds known to the Mortgage Trustee to be held by or any person
controlling or controlled by or under common control with the Company shall be
disregarded (Article I).

DEFAULTS AND NOTICE THEREOF

     The following constitute events of default under the Mortgage (a "Mortgage
Event of Default"):  (i) defaults in the payment of principal of any Bond or
prior lien obligation; (ii) default for 60 days in the payment of interest on
any Bond or any prior lien obligations, or in the payment of any sinking,
replacement, purchase or analogous fund; (iii) default for 60 days after notice
in the performance of any other covenant in the Mortgage or in any prior lien
mortgage in certain cases; (iv) default occurs in observing or performing any
covenant or condition in any mortgage constituting a prior lien on mortgaged
property and the mortgagee or trustee thereunder institutes proceedings to
invoke rights or remedies available by reason of such default, and (v) certain
events of bankruptcy, insolvency or reorganization (Section 9.02). The 15th
Supp., 16th Supp., 18th Supp., 19th Supp., 20th Supp., 21/st/ Supp and 22/nd/
Supp. provide that the following also constitute events of default under the
Mortgage:  (i) default in the payment of principal of any Bond of the Fourteenth
Series, Fifteenth Series, Sixteenth Series, Seventeenth Series, Eighteenth
Series, Nineteenth Series or Twentieth Series, respectively, at maturity or upon
redemption pursuant to the provisions of any sinking, replacement, purchase or
analogous fund or pursuant to any optional or other redemption or otherwise
provided if payment is made by wire transfer reasonably expected to be effective
on such due date, which transfer is not credited to the Bondholder's account on
such date, default shall not occur until after five days following the due date;
(ii) and default for ten days in the payment of interest on any Bond of the
Fourteenth Series, Fifteenth Series, Sixteenth Series, Seventeenth Series,
Eighteenth Series, Nineteenth Series or Twentieth Series respectively (15th
Supp., Section 6.1; 16th Supp., Section 6.1; 18th Supp., Section 6.1; 19th
Supp., Section 6.1; 20th Supp., Section 7.1; 21/st/ Supp. Section 7.1 and
22/nd/ Supp. Section 7.1). The 15th Supp., 16th Supp., 18th Supp., 19th Supp.,
20th Supp. 21/st/ Supp. and 22/nd/ Supp. also provide that it shall be an event
of default under the Mortgage if the Company shall default in the performance of
or compliance with any covenant, condition or term in the Mortgage or the 15th
Supp., 16th Supp., 18th Supp., 19th Supp., 20th Supp., 21/st/ Supp. or 22/nd/
Supp., respectively, and such default shall continue for 30 days after the
Company shall have knowledge thereof. Within 90 days after the occurrence
thereof, the Mortgage Trustee shall give notice of any defaults to the
Bondholders, provided that in the case of default in the payment of principal of
or interest on any Bond or of any sinking fund or purchase fund installment, the
Mortgage Trustee is not required to give notice to the Bondholders of any
default under the Mortgage if the Mortgage Trustee in good faith determines that
the withholding of such notice is in the interest of the Bondholders (Section
11.05). Periodic evidence of compliance with certain provisions of the Mortgage
is required to be submitted to the Mortgage Trustee (Sections 5.09, 5.12, 5.18
and 5.19). The Mortgage Trustee, subject to its duty to use the same degree of
care and skill as a prudent man would use in the conduct of his own affairs
(Section 11.02), before proceeding to enforce the lien of the Mortgage, is

                                      -18-
<PAGE>
 
entitled to be indemnified to its satisfaction against all its prospective
costs, expenses, and liability in connection therewith.  (Section 11.01)

DISCHARGE AND SATISFACTION

        Whenever all amounts due or to become due on all outstanding Bonds
issued under the Mortgage shall have been paid or provision for the payment
thereof shall have been made (as such provision for payment is defined below),
and all amounts payable by the Company to the Mortgage Trustee under the
Mortgage shall have been paid, the Mortgage Trustee shall, upon the request and
at the expense of the Company, satisfy or discharge the Mortgage of record
wherever recorded, and convey, transfer, assign, and deliver the mortgaged
property to or upon the order of the Company, and all the title, estate, rights,
and powers of the Mortgage Trustee shall forthwith cease, the mortgaged property
shall revert to the Company, and all responsibility of the Mortgage Trustee and
all obligations of the Company under the Mortgage (except as expressly provided
therein) shall then cease.

       "Provision for payment of a Bond" shall be deemed to have been made if
(a) when the principal of such Bond shall have become due and payable, whether
by maturity, call for redemption, declaration, or otherwise, all amounts due
thereon shall have been paid or shall have been deposited in trust with and
shall be held by the Mortgage Trustee for the account of the holder thereof, or
(b) at any time in advance of the maturity thereof, the Company (1) shall have
either (i) deposited with the Mortgage Trustee in trust all amounts to become
due thereon up to and upon the maturity date thereof or (ii) duly called such
Bond for redemption on a date specified, in accordance with the provisions of
the Mortgage, given all notices required to make such call effective or made
provision satisfactory to the Mortgage Trustee for giving all such notices, and
deposited with the Mortgage Trustee in trust all amounts to become due upon such
Bond up to and upon such redemption date, and (2) shall have irrevocably
authorized the Mortgage Trustee forthwith to pay to the holder thereof, out of
the funds so deposited with it, all amounts so to become due on such Bond up to
and upon the maturity date or the redemption date, as the case may be, such
payment to be made upon such Bond whenever the same shall be presented for that
purpose without awaiting the maturity date or the redemption date, and shall
have given at least one notice by publication of such deposit and authorization
or shall have made provision satisfactory to the Mortgage Trustee for giving
such notice.

                            PLAN OF DISTRIBUTION

     The Notes are being offered on a continuing basis by the Company through
the Agents, each of which has agreed to use reasonable best efforts to solicit
purchases of the Notes. The Notes may also be sold to an Agent as principal for
reoffering as described below. The Company will have the sole right to accept
offers to purchase Notes and may reject any proposed purchase of Notes in whole
or in part. Each Agent will have the right, in its discretion reasonably
exercised, to reject any proposed purchase of Notes through it in whole or in
part. The Company will pay a commission to an Agent, depending upon maturity,
ranging from ____% to ____% of the principal amount of any Notes sold through
such Agent.

     Unless otherwise specified in the applicable Pricing Supplement, any Notes
sold to an Agent as principal will be purchased by such Agent at a price equal
to 100% of the principal amount thereof less a percentage equal to the
commission applicable to any agency sale of a Note of identical maturity. Such
Note may be resold by an Agent to investors and other purchasers from time to
time in one or more transactions, including negotiated transactions, at a fixed
public offering price or at varying prices determined at the time of sale or may
be resold to certain dealers. Resales of notes by an Agent to a dealer may be
made at a discount, which will not be in excess of the discount to be received
by such Agent from the Company. After the initial public offering of Notes, the
public offering price (in the case of Notes to be resold on a fixed public
offering price basis), the commission and the discount may be changed.

     The Company reserves the right to withdraw, cancel or modify the offer made
hereby without notice and may reject orders in whole or in part placed through
an Agent.

     Unless otherwise specified in an applicable Pricing Supplement, payment of
the purchase price of the Notes will be required to be made in immediately
available funds in New York City on the date of settlement.

     No Note will have an established trading market when issued. The Notes will
not be listed on any securities exchange. Each Agent may from time to time
purchase and sell Notes in the secondary market, but no Agent is obligated to do
so, and there can be no assurance that there will be a secondary market for the
Notes or liquidity in the secondary market if one develops. From time to time,
the Agents may make a market in the Notes but are not obligated to do so and may
discontinue such market-making activity at any time.

     In connection with the offering, the rules of the Commission permit the
Agents to engage in certain transactions that stabilize the price of the Notes.
Such transactions consist of bids or purchases for the purpose of pegging,
fixing or maintaining the price of the Notes.

     If the Agents create a short position in the Notes in connection with an
offering of Notes (i.e., if they sell more Notes than are set forth on the cover
page of the Pricing Supplement), the Agents may reduce that short position by
purchasing Notes in the open market.

     PaineWebber Incorporated, on behalf of the Agents, may also impose a
penalty bid on certain of the Agents. This means that if PaineWebber
Incorporated, on behalf of the Agents, purchases Notes in the open market to
reduce the Agents' short position or to stabilize the price of the Notes, it may
reclaim the amount of the selling concession from the Agents who sold the Notes
as part of the offering.

     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases.  The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
to discourage resales of the security.

     Neither the Company nor any of the Agents makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above might have on the price of the Notes.  In addition, neither the
Company nor any of the Agents make any representation that they will engage in
such transactions or that such transactions, once commenced, will not be
discontinued without notice.

     The Agents may be deemed to be "underwriters" within the meaning of the
Securities Act of 1933, as amended. The Company has agreed to indemnify the
Agents against certain liabilities, including liabilities under 

                                      -19-

such Act, and to contribute to payments the Agents may be required to make in
respect thereof. In addition, the Company has agreed to reimburse the Agents for
certain expenses related to the offering made hereby.

                                 LEGAL MATTERS

     Certain legal matters will be passed upon for the Company by Dechert Price
& Rhoads, Philadelphia, Pennsylvania, counsel to the Company, and for the Agents
by Chapman and Cutler, Chicago, Illinois.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Under Section 14A:3-5 of the New Jersey Business Corporation Act, the Company:

     (1)  has power to indemnify each director and officer of the Company (as
well as its employees and agents) against expenses and liabilities in connection
with any proceeding involving him by reason of his being or having been such
director or officer, other than a proceeding by or in the right of the Company,
if (a) such director or officer acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company, and (b) with respect to any criminal proceeding, such director or
officer had no reasonable cause to believe his conduct was unlawful;

     (2)  has power to indemnify each director and officer of the Company
against expenses in connection with any proceeding by or in the right of the
Company to procure a judgment in its favor which involves such director or
officer by reason of his being or having been such director or officer, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interest of the Company; however, in such proceeding no
indemnification may be provided in respect to any claim, issue or matter as to
which such director or officer shall have been adjudged to be liable to the
Company, unless and only to the extent that the court determines that the
director or officer is fairly and reasonably entitled to indemnity for such
expenses as the court shall deem proper;

     (3)  must indemnify each director and officer against expenses to the
extent that he has been successful on the merits or otherwise in any proceeding
referred to in (1) and (2) above or in defense of any claim, issue or matter
therein; and

     (4)  has power to purchase and maintain insurance on behalf of a director
or officer against any expenses incurred in any proceeding and any liabilities
asserted against him by reason of his being or having been a director or
officer, whether or not the Company would have the power to indemnify him
against such expenses and liabilities under the statute.

     As used in the statute, "expenses" means reasonable costs, disbursements
and counsel fees, "liabilities" means amounts paid or incurred in satisfaction
of settlements, judgments, fines and penalties, and "proceedings" means any
pending, threatened or completed civil, criminal, administrative or arbitrative
action, suit or proceeding, and any appeal therein and any inquiry or
investigation which could lead to such action, suit or proceeding.

                                     II-1
<PAGE>
 
     Indemnification may be awarded by a court under (1) or (2) as well as under
(3) above, notwithstanding a prior determination by the Company that the
director or officer has not met the applicable standard of conduct.

     Indemnification under the statute does not exclude any other rights to
which a director or officer may be entitled under a certificate of
incorporation, by-law, or otherwise.

     Article VII of the Company's Bylaws provides, in pertinent part, as
follows:

     (1) the Company shall indemnify any corporate agent against his expenses
and liabilities in connection with any proceedings involving the corporate agent
by reason of his being or having been such a corporate agent to the extent that
(a) such corporate agent is not otherwise indemnified; and (b) the power to do
so has been or may be granted by statute; and for this purpose the Board of
Directors of the Company may, and on request of any such corporate agent shall
be required to, determine in each case whether or not the applicable standards
in any such statute have been met, or such determination shall be made by
independent legal counsel if the Board so directs or if the Board is not
empowered by statute to make such determination;

     (2) to the extent that the power to do so has been or may be granted by
statute, the Company shall pay expenses incurred by a corporate agent in
connection with a proceeding in advance of the final disposition of the
proceeding upon receipt of an undertaking by or on behalf of such corporate
agent to repay such amount unless it shall ultimately be determined that he is
entitled to be indemnified as provided by statute;

     (3) the indemnification provided in the Company's Bylaws shall not be
exclusive of any other rights to which a corporate agent may be entitled, both
as to any action in his official capacity or as to any action in another
capacity while holding such office, and shall inure to the benefits of the
heirs, executors, or administrators of any such corporate agent; and
 
     (4) the Board of Directors of the Company shall have the power to (a)
purchase and maintain, at the Company's expense, insurance on behalf of the
Company and on behalf of others to the extent that power to do so has been or
may be granted by statute and (b) give other indemnification to the extent
permitted by law.

     The Company maintains and pays all premiums on directors and officers
liability insurance policies with a primary liability limit of $35,000,000.

information with respect to the plan of distribution not previously disclosed in
this Registration Statement or any material change to such information in this
Registration Statement;

     (2)  that, for the purpose of determining any liability under the
Securities Act of 1933, as amended, each post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof; and

     (3)  to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

B.   Undertaking required by Item 512(b) of Regulation S-K.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
undersigned Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934, as amended that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

C.   Undertaking required by Item 512(h) of Regulation S-K.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended, may be permitted to directors, officers and controlling
persons of the undersigned Registrant pursuant to the foregoing provisions, or
otherwise, the undersigned Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the undersigned Registrant of expenses incurred or paid by a
director, officer or controlling person of the undersigned Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the undersigned Registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

as set forth in the Twenty-Second Supplemental Indenture dated________, 1998
referred to below.

     All payments of principal hereof and interest hereon shall be paid at the
corporate trust office of the Trustee, or at such other places as the Company
may agree, in such coin or currency of the United States of America as at the
time of payment shall constitute legal tender for the payment of public and
private debts; provided however, that any such payments of principal and
interest shall be subject to receipt of certain credits against such payment
obligations as set forth in the Twenty-Second Supplemental Indenture dated
________, 1998 referred to below.

     This Bond is one of an authorized issue of Bonds of the Company, designated
as its First Mortgage Bonds, without specified limit as to aggregate authorized
principal amount and issuable in one or more series (each of which is
hereinafter referred to as a "Series"), all issued or to be issued under and
(except in respect of any sinking, replacement, purchase, or other analogous
fund provided in said indenture or in any supplement thereto for any one or more
particular series of Bonds) equally and ratably secured by an indenture dated
October 1, 1947 (hereinafter called the "Original Indenture") between the
Company and Guarantee Bank and Trust Company, as predecessor trustee, as
supplemented by indentures supplemental thereto, including a Twenty-Second
Supplemental Indenture dated as of_______, 1998 (hereinafter called the "Twenty-
Second Supplement"), duly executed by the Company to the Trustee, to which
Original 

                                      -6-
<PAGE>
 
Indenture and all indentures supplemental thereto (herein sometimes collectively
called the "Indenture") reference is hereby made for a description of the
property mortgaged and pledged and the respective rights of the Company, the
Trustee, and the Bondholders in respect thereof, and for a specification of the
principal amount of said Bonds from time to time issuable thereunder and the
conditions upon which said Bonds may be issued and shall be secured.

     The Bonds of the 10% Medium Term Notes Series A, of which this Bond is one,
are of similar tenor hereto, and are limited to the aggregate authorized
principal amount of $100,000,000, except as provided in Section 2.11 of the
Original Indenture (relating to replacement of mutilated, lost, destroyed or
stolen Bonds).

     On certain defaults by the Company, as provided in the Indenture, the
principal of said Bonds may become payable in advance of the expressed maturity
thereof.

     As more fully provided in the Indenture, the Bonds of this Series are
subject to redemption, either as a whole or in part from time to time, on not
more than 60 nor less than 30 days' written notice in advance of the date fixed
for redemption through the application of proceeds from the condemnation of
property subject to the lien of the Indenture, or proceeds of sale of such
property to a governmental body or agency having the power of eminent domain
made as the result of the threat (evidenced in writing by such body or agency)
of condemnation of such property, but not through the application of funds from
any other source, upon payment of the principal amount thereof together with
accrued interest to the date fixed for redemption.  Except as set forth in this
paragraph, the Bonds of this Series are not subject to redemption.

     This Bond is transferable, but only as provided in the Indenture and the
Indenture of Trust dated as of_______, 1998, between the Company and The Bank of
New York, as trustee, upon surrender hereof, by the registered owner in person
or by attorney duly authorized in writing, at either of said offices where the
principal hereof and interest hereon are payable.  Upon any such transfer a new
fully registered Bond similar hereto will be issued to the transferee.  This
Bond may in like manner be exchanged for one or more new fully registered Bonds
of the same series of other authorized denominations but of the same aggregate
principal amount.  No service charge shall be made for any such transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto.  The
Company and the Trustee hereunder and any paying agent 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
the interest hereon and for all other purposes; and neither the Company nor the
Trustee hereunder nor any paying agent shall be affected by any notice to the
contrary.

     The Bonds of this series are issuable only in fully registered form, in any
denomination authorized by the Company.

     As more fully provided in the Indenture, any of the provisions of the
Indenture or any Bonds issued pursuant thereto may be altered, amended, or
eliminated, or additional provisions 


                                      -7-
<PAGE>
 
added, with the consent of the holders or registered owners (evidenced as
provided in the Indenture) of at least 66 2/3% in principal amount of the bonds
issued thereunder and then outstanding, or, if such change pertains only to the
Bonds of one or more Series but less than all Series of Bonds outstanding, the
holders or registered owners of at least 66 2/3% in principal amount of the then
outstanding Bonds of each Series to which such change pertains; provided,
however, that none of the provisions of any Bond with respect to the time,
terms, manner, or amount of any payment of the principal thereof or interest
thereon shall be changed without the consent of the holder or registered owner
of such Bond nor shall there be reduced the percentage of Bonds the holders of
which are required to consent to the execution of any supplemental indenture.


     No recourse under or upon any obligation, covenant or agreement contained
in the Indenture or in any indenture supplemental thereto, or in any Bond issued
under the Indenture or coupon thereby secured or because of any indebtedness
thereby secured, shall be had against any incorporator, or against any past,
present or future stockholder, officer or director, as such, of the Company or
of any successor corporation, either directly or through the Company or any
successor corporation, under any rule or law, statue or constitutional provision
or by the enforcement of any assessment or by any legal or equitable proceeding
or otherwise, it being expressly agreed and understood that the Indenture and
any indenture supplemental thereto, and the obligations thereby secured, are
solely corporate obligations, and that no personal liability whatever shall
attach to, or be incurred by, such incorporators, stockholders, officers or
directors, as such, of the Company, or of any successor corporation, or any of
them, because of the incurring of the indebtedness thereby authorized, or under
or by reason of any of the obligations, covenants or agreements contained in the
Indenture or in any indenture supplemental thereto, or in any of the Bonds or
coupons thereby secured, or implied therefrom.

     The execution by the Trustee, or by its successor in trust under the
Indenture, of the Trustee's certificate of authentication set forth hereon is
essential to the validity of this Bond.

     IN WITNESS WHEREOF, SOUTH JERSEY GAS COMPANY has caused this Bond to be
duly executed by the manual or facsimile signatures of its proper officers under
its corporate seal or a facsimile thereof.

     IT IS HEREBY FURTHER COVENANTED, DECLARED AND AGREED by and between the
Company and the Trustee for the benefit of those who shall hold Bonds of the
Twentieth Series, or any of them, as follows:

                                   ARTICLE I

                  DESCRIPTION OF BONDS OF THE TWENTIETH SERIES


     SECTION 1.1    The Bonds of the Twentieth Series shall be designated
as "South Jersey Gas Company First Mortgage Bonds, 10% Medium Term Notes Series
A," and shall be issuable as fully registered Bonds, substantially in the form
hereinbefore recited, but they may bear and contain such legends and
modifications as may be required by law or as may be necessary to comply with
requirements of any stock exchange or of any regulatory board, body or official
and shall be issued initially to the Trustee.  Except as provided in Section
2.11 of the Original Indenture, the aggregate principal amount of Bonds
authorized by the Twenty-Second Supplement is limited to $100,000,000, and
except as aforesaid, and except for exchanges and transfers, the Company shall
not execute and the Trustee shall not authenticate or deliver Bonds of the
Twentieth Series in excess of such aggregate principal amount.

     SECTION 1.2    Except as otherwise provided in Section 2.11 of the Original
Indenture, Bonds of the Twentieth Series shall be dated and shall bear interest
from the May 1 or November 1 next preceding the date of authentication thereof
by the Trustee, except that if the authentication date is an interest payment
date, such Bonds shall be dated, and shall bear interest from, the
authentication date; provided, however, that if upon authentication of any Bonds
of the Twentieth Series upon transfer or in exchange for other such Bonds,
interest on the Bonds of the Twentieth Series shall be in default, the date from
which such Bond shall bear interest shall be the date to which interest shall
have been paid upon the Bonds transferred or surrendered in exchange for the
Bond so authenticated; and provided further, however, that in the case of the
authentication of Bonds of the 

                                      -12-
<PAGE>
 
Twentieth Series upon an original issue hereunder, such Bonds may be dated the
date of authentication thereof and in such case shall bear interest from such
date of authentication.

     SECTION 1.3    Bonds of the Twentieth Series shall mature_______, 2038, and
shall bear interest on the unpaid principal amount thereof at the rate of 10%
per annum (computed on the basis of a 360-day year of twelve 30-day months),
payable on May 1 and November 1 in each year, until the obligation of the
Company with respect to the payment thereof shall be discharged; provided,
however, that the Company shall receive certain credits against principal and
interest as set forth in Section 2.1 hereof.  Subject to the provisions of
Section 2.1 below, all payments of principal and interest shall be made at the
corporate trust office of the Trustee, or at such other places as the Company
may agree, in such coin or currency of the United States of America as at the
time of payment shall constitute legal tender for the payment of public and
private debts.

     SECTION 1.4    Bonds of the Twentieth Series shall be issuable only in the
form of fully registered Bonds in any denomination authorized by the Company.

     SECTION 1.5    Bonds of the Twentieth Series shall be transferable and
exchangeable, but only as provided in the Indenture and the Note Indenture, upon
surrender thereof for cancellation by the registered owner in person or by
attorney duly authorized in writing at either of said offices.  The Company
hereby waives any right to make a charge for any transfer or exchange of Bonds
of the Twentieth Series, but the Company may require payment of a sum sufficient
to cover any tax or any other governmental charge that may be imposed in
relation thereto.

     SECTION 1.6    On the Substitution Date (as defined below), the Trustee
will deliver to the Company for cancellation all Bonds of the Twentieth Series.
The Company will cause the Trustee to provide notice to all holders of Bonds of
the Twentieth Series prior to the occurrence of the Substitution Date.
"Substitution Date" shall mean the date that all Bonds issued and outstanding
under the Indenture, other than the Bonds of the Twentieth Series (the "First
Mortgage Bonds"), have been retired (at, before or after the maturity thereof)
through payment, redemption or otherwise (including those First Mortgage Bonds
deemed to be paid within the meaning of the Indenture).

                                      -13-
<PAGE>
 
     SECTION 1.7    Bonds of the Twentieth Series shall be subject to
redemption, either as a whole or in part from time to time upon payment of the
principal amount thereof through the application pursuant to Subdivision C of
Section 6.07 of the Original Indenture of proceeds from the condemnation of
property subject to the lien of the Indenture, or proceeds of sale of such
property to a governmental body or agency having the power of eminent domain
made as a result of the threat (evidenced in writing by such body or agency) or
condemnation of such property, but not through the application of money from any
other source together with accrued interest to the date fixed for redemption.
Except as set forth in this Section 1.7, the Bonds of the Twentieth Series are
not subject to redemption.

     The election of the Company to redeem any of the Bonds of the Twentieth
Series shall be evidenced by a resolution of its Board of Directors calling all
or a stated principal amount thereof for redemption on a stated date.  At least
40 days prior to such redemption date (or at such later time as shall be
satisfactory to the Trustee), the Company shall file with the Trustee a
certified copy of such resolution.  The Company shall on or before such
redemption date deposit with the Trustee the total redemption price of all Bonds
so called, with accrued interest thereon to the redemption date.

     If the Company elects to redeem less than all of the Bonds of the Twentieth
Series, the particular Bonds to be redeemed shall be selected by the Trustee in
the manner set forth in this Section 1.7 of the Twenty-Second Supplement from
the Bonds of the Twentieth Series then outstanding.  The Trustee shall certify
to the Company the numbers of the Bonds selected and the portion of the
principal amount of each Bond that is to be redeemed.

     The Trustee shall, not more than 60 nor less than 30 days in advance of
such redemption date, give, in the name of the Company, written notice that
Bonds of the Twentieth Series bearing the serial numbers specified have been
called for redemption, that they will be due and payable on such redemption date
at the corporate trust office of the Trustee at a stated amount (which shall be
the applicable redemption price), and that all interest thereon will cease to
accrue after said date (unless the Company shall default in payment of the
amount necessary to effect such redemption).  If all the Bonds of the Twentieth
Series be called, the notice shall so state and may omit the numbers thereof.
The notice shall state that the Bonds will be payable at the stated redemption
price, plus accrued interest to the redemption date.  If the redemption date is
an interest payment date, the notice may state that the interest payment due on
such date will be paid in the usual manner.  Such notice of redemption shall be
given to the registered owners of Bonds which, or portions of which, are to be
redeemed by mailing the same to such registered owners, at their respective
addresses as the same appear on the aforementioned registry books.

     Before any money shall be applied by the Trustee to the redemption of Bonds
under this Section, the Company shall deliver to the Trustee a certificate of
the President or a Vice President of the Company stating that all conditions
precedent provided for herein (including compliance with all applicable
covenants) relating to such redemption have been complied with.

                                      -14-
<PAGE>
 
     Each Bond so called for redemption shall be due and payable at the places
and price and on the date specified in such notice.  Subject to any agreement as
described below, beginning on the date when each Bond shall be due and payable
as aforesaid, the holder thereof may present the same for redemption, in
negotiable form, and the Trustee shall, out of the money deposited with it under
the provisions of this Section, cause the same to be paid and redeemed; after
said date (unless upon such presentation on or after the due date the Trustee
shall have refused or failed to make such payment) all further interest shall
cease to accrue thereon.  In any case where the redemption date is an interest
payment date, the interest payment due on such date on Bonds called for
redemption may be paid in the usual manner.

     Whenever less than all of the outstanding Bonds of the Twentieth Series are
to be redeemed, the principal amount of Bonds of the Twentieth Series to be
redeemed, shall be prorated among the holders of the Bonds of the Twentieth
Series in the proportion, as nearly as practicable, that their respective
holdings bear to the aggregate principal amount of Bonds of the Twentieth Series
outstanding on the date of selection.  In making any proration pursuant to this
provision, the Trustee may make such adjustment as it may determine, with the
approval of the Company, to the end that the principal amount prorated to each
holder of Bonds shall be in each instance $1,000 or an integral multiple
thereof.

     If only a part of any fully registered Bond shall be selected by the
Trustee in the manner set forth above, the notice of redemption hereinbefore
provided for shall specify the distinctive number of such Bond and the portion
of the principal amount thereof to be redeemed.  Upon surrender of such Bond for
partial redemption and upon payment of the portion so called for redemption, a
new Bond or Bonds of the Twentieth Series, in aggregate principal amount equal
to the unredeemed portion of such surrendered Bond, shall be executed by the
Company, authenticated by the Trustee, and delivered to the registered owner
thereof, without expense to such holder.

     The Company may enter into an agreement with the registered owners of any
Bond of the Twentieth Series (or prospective registered owner of any such Bond)
providing for the payment without the surrender of such Bond to such registered
owner (or to such prospective registered owner, upon becoming a registered owner
of any such Bond) of the principal of and the premium, if any, and interest on
such Bond or any part thereof at a place other than the offices or agencies
therein specified, and for the making of notation as to principal payments, if
any, on such Bond by such registered owner or by any agent of the Company or of
the Trustee.  A copy of any such agreement shall be filed with the Trustee.  The
Trustee is authorized to approve any such agreement, and shall thereafter make
all payments on such Bond as provided in such agreement.  The Trustee shall not
be liable for any act or omission to act on the part of the Company, any such
registered owner or any agent of the Company in connection with any such
agreement.

     So long as any of the Bonds of the Twentieth Series shall remain
outstanding, upon any application by the Trustee of funds from sources described
in this Section 1.7 of the Twenty-Second Supplement to the redemption of Bonds
pursuant to Subdivision C of Section 6.07 of the 

                                      -15-
<PAGE>
 
Original Indenture, if less than all Bonds of all Series then outstanding are to
be redeemed, a principal amount of Bonds of the Twentieth Series shall be
redeemed by the application of a portion of such funds, such portion to be
determined by multiplying the total amount of such funds so to be applied by a
fraction the numerator of which shall be the aggregate amount required for the
redemption, pursuant to Subdivision C of Section 6.07 (exclusive of accrued
interest, if any), of all of the Bonds of the Twentieth Series outstanding on
the date of the selection for such redemption and the denominator of which shall
be the aggregate amount required for the redemption, pursuant to such
Subdivision C of Section 6.07 (exclusive of accrued interest, if any), of all of
the Bonds of all Series outstanding on such date; provided, however, that
nothing in this Section 1.7 shall restrict the manner (pro rata, by lot or
otherwise) by which the remaining balance of such funds shall be applied to the
redemption of Bonds of any Series other than the Twentieth Series.

                                   ARTICLE II

             CREDITS WITH RESPECT TO BONDS OF THE TWENTIETH SERIES

     SECTION 2.1    In addition to any other credit, payment or satisfaction to
which the Company is entitled with respect to the Bonds of the Twentieth Series,
the Company shall be entitled to credits against amounts otherwise payable in
respect of the Bonds of the Twentieth Series in an amount corresponding to (i)
the principal amount of any of the Company's Notes issued under the Note
Indenture surrendered to the Note Trustee by the Company, or purchased by the
Note Trustee, for cancellation, (ii) the amount of money held by the Note
Trustee and available and designated for the payment of principal of, and/or
interest on, the Notes, regardless of the source of payment to the Note Trustee
of such moneys and (iii) the amount by which principal of and interest due on
the Bonds of the Twentieth Series exceeds principal of and interest due on the
Notes.  The Note Trustee shall make notation on such Bonds authorized hereby of
any such credit.

     SECTION 2.2    A certificate of the Company signed by the President or any
Vice President, and attested to by the Secretary or any Assistant Secretary, and
consented to by the Note Trustee, stating that the Company is entitled to a
credit under Section 2.1 hereof or that Bonds of the Twentieth Series have been
canceled, and setting forth the basis therefor in reasonable detail, shall be
conclusive evidence of such entitlement, and the Trustee shall accept such
certificate as such evidence without further investigation or verification of
the matters stated therein.

     SECTION 2.3    Notwithstanding anything in this Supplemental Indenture to
the contrary the obligation of the Company to make payment with respect to the
principal of and premium, if any, and interest on the Bonds of the Twentieth
Series shall be deemed satisfied and discharged: (i) on the Substitution Date or
(ii) if at any time: (x) the Company shall have paid or caused to be paid the
principal of and premium, if any, and interest on all the outstanding Notes, as
and when the same shall have become due and payable, (y) the Company shall have
delivered 

                                      -16-
<PAGE>
 
to the Note Trustee for cancellation all outstanding Notes, or (z) the
Company shall have irrevocably deposited or caused to be irrevocably deposited
with the Note Trustee as trust funds the entire amount in (A) cash, (B) U.S.
Government obligations maturing as to principal and interest in such amounts and
at such times as will insure the availability of cash, or (C) a combination of
cash and U.S. Government obligations, in any case sufficient, without
reinvestment, as certified by an independent public accounting firm of national
reputation in a written certification delivered to the Trustee, to pay at
maturity or the applicable redemption date (provided that notice of redemption
shall have been duly given or irrevocable provision satisfactory to the Note
Trustee shall have been duly made for the giving of any notice of redemption)
all outstanding Notes, including principal and any premium and interest due or
to become due to such date of maturity, as the case may be.

     When the obligation of the Company to make payment with respect to the
principal of and premium, if any, and interest on the Bonds of the Twentieth
Series shall be satisfied or deemed satisfied pursuant to this Section  2.3
hereof, the holders of Bonds of the Twentieth Series shall, upon written request
of the Company, deliver without cost to the Company all of the Bonds of the
Twentieth Series, together with such appropriate instruments of transfer or
release as may be reasonably requested by the Company.  All Bonds of the
Twentieth Series delivered to the Company in accordance with this Section 2.3
shall be delivered by the Company to the Trustee for cancellation.

                                  ARTICLE III

                      ADDITIONAL COVENANTS OF THE COMPANY

     SECTION 3.1    So long as any Bonds of the Twentieth Series shall remain
outstanding, the Company will not declare or pay any dividend on any shares of
its Common Stock (other than dividends payable in shares of its Common Stock) or
make any distribution on such shares, or purchase or otherwise acquire any such
shares (except shares acquired without cost to the Company), or advance any
amount to or invest any amount in the property, securities or indebtedness of,
or guarantee any indebtedness of, any subsidiary if, after giving effect to such
action, the sum of the aggregate amounts so declared, paid, distributed,
purchased, acquired, advanced, invested or guaranteed after December 31, 1997
would exceed the aggregate net income of the Company available for dividends on
its Common Stock earned after such date plus the sum of $56,000,000.  For the
purposes of this Section 3.1, "subsidiary" shall mean any corporation directly
or indirectly controlled by or under common control with the Company.

     For the purpose of calculating the requirements of this Section 3.1, the
net income of the Company available for dividends on its Common Stock shall be
determined in accordance with such system of accounts as may be prescribed by
any governmental authority having jurisdiction in the premises or in the absence
thereof in accordance with generally accepted accounting principles as in effect
at such time; provided, however, that (a) the deductions for depreciation or
renewal or 

                                      -17-

replacement reserves in respect of each year shall be the amount taken therefor
on the accounts of the Company or the amount required to be stated in item (1)
of the Replacement Fund Certificate to be filed under Section 5.19 of the
Original Indenture with respect to the period ending at the close of such year,
whichever be greater, and (b) no deduction or adjustment shall be made from
gross income for or in respect of (i) expenses in connection with the redemption
or retirement of any securities issued by the Company, including any amount paid
in excess of the principal or par or stated value of securities redeemed or
retired, and, if such redemption or retirement is effected with the proceeds of
sale of other securities of the Company, interest on the securities redeemed or
retired from the date on which the funds required for such redemption or
retirement shall be deposited in trust for such purpose to the date of such
redemption or retirement, (ii) profits or losses from sales of capital assets or
taxes in respect of such profits, (iii) any adjustments to retained earnings
(including tax adjustments) applicable to any period prior to January 1, 1998,
(iv) charges for the write-off of unamortized debt discount and expense carried
on the books of the Company at December 31, 1997, or (v) charges for the write-
off or write-down of the amount at which any property of the Company was carried
on its books at December 31, 1997, to the extent that the same shall be approved
by, or be made pursuant to any rule, regulation, or order of, any governmental
authority having jurisdiction in the premises and shall not be required by such
authority to be charged against earnings accumulated after December 31, 1997.

     SECTION 3.2    So long as any Bonds of the Twentieth Series shall remain
outstanding, the Company will satisfy its obligations under the Replacement Fund
provided for in Section 5.19 of the Original Indenture first through the use of
all available property additions and retired Bonds of any Series and then, if
and only to the extent that said property additions and retired Bonds are not
sufficient to satisfy such obligations, through the use of cash.

     SECTION 3.3    So long as any Bonds of the Twentieth Series remain
outstanding, in the event that the Company shall consolidate or merge with or
into any corporation or corporations, or the Company shall transfer all of its
property and franchises to any other corporation, the corporation formed by any
such consolidation, or into which the Company shall be so merged, or which shall
acquire such property of the Company, shall be a corporation incorporated under
the laws of the United States, any State or the District of Columbia.

     SECTION 3.4    So long as any Bonds of the Twentieth Series shall remain
outstanding, no owner of any portion of the mortgaged property will be entitled
to any credit against interest payable on any Bonds by reason of the payment of
any tax on such property.

                                   ARTICLE V

                      AMENDMENT TO THE ORIGINAL INDENTURE

     SECTION 5.1    Section 3.06. of the Original Indenture shall be amended to
delete paragraph (2) of subsection A thereof, so that such Section shall
thereafter read in full as follows:

               "SECTION 3.06.  ADDITIONAL BONDS - CONDITIONS FOR AUTHENTICATION
          - ACQUISITION OR REFUNDING OF BONDS ISSUED HEREUNDER.  Whenever any
          Bonds shall have been acquired, paid, or retired by the Company, or
          whenever the Company shall have made provision for the payment of any
          Bonds (as such provision for payment is defined in Article I), or
          shall surrender any Bonds to the Trustee, thereupon or at any time
          thereafter additional Bonds shall be authenticated and delivered by
          the Trustee in a principal amount not exceeding the principal amount
          of the Bonds so acquired, paid, retired, surrendered, or for the
          payment of which such provision shall have been made, upon application
          by the Company and upon compliance with the following conditions, in
          addition to those specified in Section 3.03:

                    A.  Any Bonds so acquired, paid, retired or surrendered, or
          for which payment shall have been so provided, may, when deposited
          with the Trustee as below provided in Subdivision B, be uncancelled or
          may have been cancelled; provided, however, that in respect of any
          which shall have been cancelled prior to or concurrently with the
          application for such authentication (and, for the purposes of this
          Subdivision A, in case payment shall have been so provided for such
          Bonds, the same shall be deemed to have been cancelled upon the date
          of such provision for payment) no Bond shall have been authenticated
          in lieu thereof or in exchange therefor or by virtue of the
          acquisition, payment, retirement, cancellation, or such provision for
          payment thereof; nor shall any money have been withdrawn hereunder by
          virtue of such acquisition, payment, retirement, cancellation, or
          provision.

                    B.  There shall be delivered to the Trustee the following
          documents:

                        (1) The Bonds so acquired, paid, retired, or
                    surrendered.  Any of such Bonds which shall be uncancelled
                    shall be in negotiable form or accompanied by proper
                    instruments of assignment and transfer, and shall be
                    accompanied by all unmatured coupons, if any, appertaining
                    thereto.  In the case of any Bonds for which payment shall
                    have been so provided, such Bonds shall not then be required
                    to be deposited, but in lieu thereof the Company shall
                    deliver to the Trustee a statement describing the same;
                    thereafter, upon payment of such Bonds, the same shall
                    forthwith be delivered to the Trustee for cancellation.  In
                    the case of any Bonds which shall have been paid or retired
                    or surrendered and which shall have theretofore been
                    cancelled and cremated by the Trustee, such Bonds shall not
                    be required to be deposited, but in lieu thereof the Company
                    shall deliver to the Trustee a statement describing the same
                    and specifying the date upon which the same were paid or
                    retired or surrendered and were cancelled and cremated.

                        (2) If the Bonds so deposited shall be cancelled Bonds,
                    or if in lieu of such deposit of Bonds a statement by the
                    Company shall be delivered as provided in subparagraph (1)
                    of this Subdivision B, a certificate by the President or a
                    Vice-President of the Company, stating such facts in
                    connection therewith as may reasonably be required to show
                    compliance with the conditions specified in Subdivision A.

                    C.  If the Bonds so acquired, paid, retired, surrendered, or
          the payment of which has been so provided for, shall not at any time
          theretofore have been bona fide issued by the Company, and if they
          shall bear interest at a lower rate per annum than the new Bonds the
          authentication of which is then applied for, the net earnings
          condition specified in Subdivision C of Section 3.04 shall be complied
          with, and the Company shall deliver to the Trustee (i) a net earnings
          certificate, conforming to the provision of Subdivision E (3) of
          Section 3.04, showing the fixed charges and net earnings of the
          Company in such reasonable detail as may be required to show
          compliance with said condition, (ii) an opinion of counsel conforming
          to the provisions of Subdivision E(4)(b) of Section 3.04, and (iii) a
          certificate by the trustee or mortgagee of each prior lien conforming
          to the provisions of Subdivision E(5) of Section 3.04"

     SECTION 5.2    The foregoing amendment to Section 3.06 of the Original
Indenture shall become effective upon the earlier to occur of the following:

          (a) the date as of which no Bonds remain outstanding that were part of
a series of Bonds initially issued prior to the issuance of Bonds of the
Twentieth Series;

          (b) the date as of which a supplemental indenture to the Indenture is
executed by the Company and the Trustee setting forth the foregoing amendment to
Section 3.06 of the Original Indenture, after the holders of at least 66 2/3% of
the Bonds then outstanding have consented to and approved the execution of such
supplemental indenture, all in accordance with Article X and the other relevant
provisions of the Original Indenture.

     SECTION 5.3    Each holder of any Bonds of the Twentieth Series, by the
acceptance by such holder of such Bonds, (a) consents to and approves the
foregoing amendment to Section 3.06 of the Original Indenture, and consents to
and approves the execution by the Company and the Trustee of a supplemental
indenture to the Indenture setting forth such amendment, and (b) agrees to
execute such instrument or instruments as may be requested by the Company or the
Trustee to evidence such consent and approval in accordance with Section 10.02
of the Original Indenture.

                                  ARTICLE VI

                            CONCERNING THE TRUSTEE

     SECTION 6.1    The Trustee, for itself and its successors in said trusts,
hereby accepts the trust hereby provided and agrees to perform the same upon the
terms and conditions contained in the Indenture, including the Twenty-Second
Supplement.  The Trustee shall not be responsible in any manner whatsoever for
the recitals in the Twenty-Second Supplement.

     SECTION 6.2    So long as any Bonds of the Twentieth Series shall remain
outstanding, any successor trustee to the Trustee shall at all times be a
corporation which shall have at all times a combined capital and surplus of not
less than $100,000,000.  If any such successor trustee publishes reports of
condition annually, pursuant to law or to the requirements of a supervising or
examining authority, the combined capital and surplus of such successor trustee
at any time for the purposes of this Section shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.

                                  ARTICLE VII

                          CONCERNING EVENTS OF DEFAULT

                                     -21-
<PAGE>
 
     SECTION 7.1    So long as any Bonds of the Twentieth Series shall remain
outstanding, the following shall constitute events of default within the meaning
of Section 9.02 of the Original Indenture (in addition to the events of default
set forth in Section 9.02 of the Original Indenture);

          (a) If the Company shall default in the payment of any portion of the
principal of any Bond of the Twentieth Series, as and when the same shall have
become due, whether at the stated maturity thereof or upon proceedings for
redemption (pursuant to the provisions of any sinking, replacement, purchase or
other analogous fund established in the Original Indenture or pursuant to any
optional or other redemption) or otherwise; provided, however, that in the event
the Company and the Trustee shall have taken all action required to be taken so
that each such payment of principal by means of wire transfer could reasonably
be expected to be effective on the due date thereof, but nevertheless, any such
transfer shall not have been credited to the account of a registered owner of
Bonds of the Twentieth Series to whom such payment is required to be made
effective as of the due date, the Company shall not be deemed to have defaulted
upon the obligation to make such payment until the expiration of five days
following said due date;

          (b) if the Company shall default in the payment of any installment of
interest due on any Bond of the Twentieth Series and such default shall continue
for a period of 10 days; or

          (c) if the Company shall default in the performance of or compliance
with any other covenant, condition or term contained in the Indenture, including
the Twenty-Second Supplement, and such default shall continue for 30 days after
the Company shall have knowledge thereof.

     SECTION 7.2    So long as any Bonds of the Twentieth Series shall remain
outstanding, the Company covenants that if at any time or times or from time to
time an event of default referred to in Section 6.1 of the Twenty-Second
Supplement shall occur, the Company will, on demand of the Trustee, forthwith
pay to the Trustee, for the benefit of all holders of Bonds then outstanding
under the Indenture, a sum equal to the total amount then due for principal and
interest on all Bonds then outstanding under the Indenture, with interest
thereon (to the extent that payment of such interest is enforceable under
applicable law) in accordance with the terms of the respective Bonds.

     Should said sum not be so paid to the Trustee, it shall be entitled, at any
time or times and from time to time, in its own name and as Trustee of an
express trust and without the possession or production of any Bonds of any
Series or coupons, to recover judgment for the same against the Company or any
other obligor upon such Bonds.

                                 MISCELLANEOUS

     SECTION 8.1    As supplemented by the Twenty-Second Supplement, the
Indenture is in all respects ratified and confirmed, and the Indenture,
including the Twenty-Second Supplement, shall be read as one instrument.  All
terms used in the Twenty-Second Supplement shall have the same meaning as used
elsewhere in the Indenture except where the context clearly indicates otherwise.

     SECTION 8.2    The Twenty-Second Supplement has been dated as of     , 1998
for convenience.  The date of actual execution hereof by each of the parties is
the date shown by the acknowledgment of execution hereof by its officers.

     SECTION 8.3    The Twenty-Second Supplement may be executed in several
counterparts, each of which shall be considered an original and all collectively
as but one instrument.

     SECTION 8.4    The approval of the New Jersey BPU of the execution and
delivery of these presents, and of the issue of any Bonds of the Twentieth
Series, shall not be construed as approval of said New Jersey BPU of any other
act, matter or thing which requires approval of said New Jersey BPU under the
laws of the States of New Jersey; nor shall the approval of said New Jersey BPU
of the issue of any such Bonds bind said New Jersey BPU or any other public body
or authority of the State of New Jersey having jurisdiction in the premises in
any future application for the issuance of Bonds under the Indenture.

     IN WITNESS WHEREOF, the Company and the Trustee have caused these presents

proper officers, all duly authorized thereunto, and have caused  these presents

Issue Date (or, if pursuant to Section 2.13 hereof, a Global Note has two or
more Original Issue Dates, interest shall, beginning on each such Original Issue
Date, begin to accrue for that part of the principal amount of such Global Note
to which that Original Issue Date is applicable), or (2) the most recent date to
which interest has been paid or duly provided for with respect to such Note
until the principal of such Note is paid or made available for payment, and
interest on each Note shall be payable on each Interest Payment Date after the
Original Issue Date.

          (d)  Each Note shall mature on a stated maturity specified in the Note
not less than one year nor more than thirty years after the applicable Original
Issue Date.  The principal amount of each outstanding Note shall be payable on
the maturity date or dates specified therein.

          (e)  Unless otherwise specified in a Company Order pursuant to Section
2.5 hereof, interest on each of the Notes shall be calculated on the basis of a
360- day year of twelve 30-day months and shall be computed at a fixed rate
until the maturity of such Notes.  The method of computing interest on any Notes
not bearing a fixed rate of interest shall be set forth in a Company Order
pursuant to Section 2.5 hereof.  Unless otherwise specified in a Company Order
pursuant to Section 2.5 hereof, principal, interest and premium, if any, on the
Notes shall be payable in the currency of the United States.

          (f)  Except as provided in the following sentence, the Person in whose
name any Note is registered at the close of business on any Regular Record Date
or Special Record Date with respect to an Interest Payment Date for such Note
shall be entitled to receive the interest payable on such Interest Payment Date
notwithstanding the cancellation of such Note upon any registration of transfer,
exchange or substitution of such Note subsequent to such Regular Record Date or
Special Record Date and prior to such Interest Payment Date.  Any interest
payable at maturity shall be paid to the Person to whom the principal of such
Note is payable.

          (g)  Promptly after each Regular Record Date that is not a date of
maturity, the Trustee shall furnish to the Company a notice setting forth the
total amount of the interest payments to be made on the applicable Interest
Payment Date, and to the Depository a notice setting forth the total amount of
interest payments to be made on Global Notes on such Interest Payment Date.  The
Trustee (or any duly selected paying agent) shall provide to the Company during
each month that precedes an Interest Payment Date a list of the principal,
interest and premium, if any, to be paid on Notes on such Interest Payment Date
and to the Depository a list of the principal, interest and premium, if any, to
be paid on Global Notes on such Interest Payment Date.  Promptly after the first
Business Day of each month, the Trustee shall furnish to the Company a written
notice setting forth the aggregate principal amount of the  Global Notes.  

                                      -11-

withholding taxes on interest paid as required by law except with respect to any
Global Note.

and subject to any conditions specified in such Opinion of Counsel, will
constitute valid and binding obligations of the Company, enforceable in
accordance with their terms, except to the extent that enforcement thereof may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws of general application relating to or affecting the enforcement of
creditors' rights and the application of general principles of equity
(regardless of whether enforcement is sought in a proceeding at law or in
equity) and except as enforcement of provisions of this Indenture may be limited
by state laws affecting the remedies for the enforcement of the security

                    (H)  that the issuance of the Notes and, if applicable, the

is bound;

                    (I)  that all consents or approvals of the New Jersey Board

          (d)  No Note shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of an authorized officer, and
such certificate upon any Note shall be conclusive evidence, and the only
evidence, that such Note has been duly authenticated and delivered hereunder and

          (e)  Notwithstanding any other provision in this Section 2.5 to the
contrary, for each issuance of Notes after the first issuance of Notes of such
series, the Company shall be required to deliver to the Trustee only the Note
and a request from an Authorized Agent to authenticate and deliver such Note in
accordance with the instructions specified therein.  Any such request shall
constitute a representation and warranty by the Company that all of the
conditions precedent provided for in this Indenture relating to the

SECTION 2.6    EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES

          (a)  Subject to Section 2.13 hereof, Notes may be exchanged for one or
more new Notes of any authorized denominations and of a like aggregate principal
amount, series and stated maturity and having the same terms and Original Issue
Date or Dates.  Notes to be exchanged shall be surrendered at any of the offices
or agencies to be maintained pursuant to Section 6.2 hereof and the Trustee
shall deliver in exchange therefor the Note or Notes which the Noteholder making
the exchange shall be entitled to receive.

          (b)  The Company hereby appoints the Trustee registrar for the Notes.
The Trustee shall keep, at one of said offices or agencies, a register or
registers in which, subject to such reasonable regulations as it may prescribe,
the Trustee shall register or cause to be registered Notes and shall register or
cause to be registered the transfer of Notes as in this Article Two provided.
Such register shall be in written form or in any other form capable of being
converted into written form within a reasonable time.  At all reasonable times,
such register shall be open for inspection by the Company.  Upon due presentment
for registration of transfer of any Note at any such office or agency, the
Company shall execute and the Trustee shall register, authenticate and deliver
in the name of the transferee or transferees one or more new Notes of any
authorized denominations and of a like aggregate principal amount, series and
stated maturity and having the same terms and Original Issue Date or Dates.

          (c)  All Notes presented for registration of transfer or for exchange,
redemption or payment shall be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Trustee and duly executed by the Holder or the attorney in fact of such
Holder duly authorized in writing.

          (d)  No service charge shall be made for any exchange or registration
of transfer of Notes, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.

          (e)  The Trustee shall not be required to exchange or register a
transfer of any Notes selected, called or being called for redemption (including
Notes, if any, redeemable at the option of the Holder, provided such Notes are
then redeemable at such Holder's option), except, in the case of any Note to be
redeemed in part, the portion thereof not to be so redeemed.

          (f)  If the principal amount, and applicable premium, if any, of part,
but not all, of a Global Note is paid, then upon surrender to the Trustee of
such Global Note, the Company shall execute, and the Trustee shall authenticate,
deliver and register, a Global Note in an authorized denomination in aggregate
principal amount equal to, and having the same terms, Original Issue Date or
Dates and series as, the unpaid portion of such Global Note.

SECTION 2.7    MUTILATED, DESTROYED, LOST OR STOLEN NOTES

          (a)  If any temporary or definitive Note shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its request the
Trustee shall authenticate and deliver, a new Note of like form and principal
amount and having the same terms and Original Issue Date or Dates and bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen.  In every case the applicant for a substituted Note shall
furnish to the Company, the 

                                      -15-
<PAGE>
 
Trustee and any paying agent or Authenticating Agent such security or indemnity
as may be required by them to save each of them harmless, and, in every case of
destruction, loss or theft of a Note, the applicant shall also furnish to the
Company and to the Trustee evidence to their satisfaction of the destruction,
loss or theft of such Note and of the ownership thereof.

          (b)  The Trustee shall authenticate any such substituted Note and
deliver the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substituted Note, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in relation thereto and any other expenses connected therewith.
If any Note which has matured, is about to mature, has been redeemed or called
for redemption shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substituted Note, pay or authorize the payment
of the same (without surrender thereof except in the case of a mutilated Note)
if the applicant for such payment shall furnish to the Company, the Trustee and
any paying agent or Authenticating Agent such security or indemnity as may be
required by them to save each of them harmless and, in case of destruction, loss
or theft, evidence satisfactory to the Company and the Trustee of the
destruction, loss or theft of such Note and of the ownership thereof.

          (c)  Every substituted Note issued pursuant to this Section 2.7 by
virtue of the fact that any Note is mutilated, destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
such destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Notes duly issued hereunder.  All Notes shall be held and
owned upon the express condition that, to the extent permitted by law, the
foregoing provisions are exclusive with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Notes and shall preclude any and all other
rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

SECTION 2.8    TEMPORARY NOTES

     Pending the preparation of definitive Notes, the Company may execute and
the Trustee shall authenticate and deliver temporary Notes (printed,
lithographed or otherwise reproduced).  Temporary Notes shall be issuable in any
authorized denomination and substantially in the form of the definitive Notes
but with such omissions, insertions and variations as may be appropriate for
temporary Notes, all as may be determined by the Company.  Every such temporary
Note shall be authenticated by the Trustee upon the same conditions and in
substantially the same manner, and with the same effect, as the definitive
Notes.  Without unreasonable delay the Company shall execute and shall deliver
to the Trustee definitive Notes and thereupon any or all temporary Notes shall
be surrendered in exchange therefor at the corporate trust office of the
Trustee, and the Trustee shall authenticate, deliver and register in exchange
for such temporary Notes an equal aggregate principal amount of definitive
Notes.  Such exchange shall be made by the Company at its own expense and
without any charge therefor to the Noteholders.  Until so exchanged, the
temporary Notes shall in all respects be entitled to the same benefits under
this Indenture as definitive Notes authenticated and delivered hereunder.

SECTION 2.9    CANCELLATION OF NOTES PAID, ETC.

     All Notes surrendered for the purpose of payment, redemption, exchange or
registration of transfer shall be surrendered to the Trustee for cancellation
and promptly canceled by it and no Notes shall be issued in lieu thereof except
as expressly permitted by this Indenture.  The Company's acquisition of any
Notes shall operate as a redemption or satisfaction of the 

                                      -16-
<PAGE>
 
indebtedness represented by such Notes and such Notes shall be surrendered by
the Company to and canceled by the Trustee.

SECTION 2.10   INTEREST RIGHTS PRESERVED

     Each Note delivered under this Indenture upon transfer of or in exchange
for or in lieu of any other Note shall carry all the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Note, and each such
Note shall be so dated that neither gain nor loss of interest shall result from
such transfer, exchange or substitution.

SECTION 2.11   SPECIAL RECORD DATE

     If and to the extent that the Company fails to make timely payment or
provision for timely payment of interest on any series of Notes (other than on
an Interest Payment Date that is a maturity date), that interest shall cease to
be payable to the Persons who were the Noteholders of such issue at the
applicable Regular Record Date.  In that event, when moneys become available for
payment of that interest, the Trustee shall (a) establish a date of payment of
such interest and a Special Record Date for the payment of that interest, which
Special Record Date shall be not more than 15 or fewer than 10 days prior to the
date of the proposed payment and (b) mail notice of the date of payment and of
the Special Record Date not fewer than 10 days preceding the Special Record Date
to each Noteholder of such issue at the close of business on the 15th day
preceding the mailing at the address of such Noteholder, as it appears on the
register for the Notes.  On the day so established by the Trustee the interest
shall be payable to the Holders of the applicable Notes at the close of business
on the Special Record Date.

SECTION 2.12   PAYMENT OF NOTES

     Payment of the principal, interest and premium on all Notes shall be
payable as follows:

          (a)  On or before 11:00 a.m., New York City time, of the day on which
payment of principal, interest and premium, if any, is due on any Global Note
pursuant to the terms thereof, the Company shall deliver to the Trustee funds
available on such date sufficient to make such payment, by wire transfer of
immediately available funds or by instructing the Trustee to withdraw sufficient
funds from an account maintained by the Company with the Trustee or such other
method as is acceptable to the Trustee and, if applicable, the Depository.  On
or before 2:00 p.m., New York City time, or such other time as shall be agreed
upon between the Trustee and, if applicable, the Depository, of the day on which
any payment of interest is due on any Global Note (other than at maturity), the
Trustee shall pay to the Depository such interest in same day funds.  On or
before 2:00 p.m., New York City time or such other time as shall be agreed upon
between the Trustee and the Depository, of the day on which principal, interest
payable at maturity and premium, if any, is due on any Global Note, the Trustee
shall deposit with the Depository the amount equal to the principal, interest
payable at maturity and premium, if any, by wire transfer into the account
specified by the Depository.  As a condition to the payment at maturity of any
part of the principal and applicable premium of any Global Note, the Depository
shall surrender, or cause to be surrendered, such Global Note to the Trustee,
whereupon a new Global Note shall be issued to the Depository pursuant to
Section 2.6(f).

          (b)  With respect to any Note that is not a Global Note, principal,
applicable premium, if any, and interest due at the maturity of the Note shall
be payable in immediately available funds when due upon presentation and
surrender of such Note at the corporate trust office of the Trustee or at the
authorized office of any paying agent.  Interest on any Note that is not a
Global Note (other than interest payable at maturity) shall be paid to the
Holder thereof as 

                                      -17-
<PAGE>
 
its name appears on the register as of the close of business on the Regular
Record Date relating to the applicable Interest Payment Date by check mailed on
such Interest Payment Date or wire transfer payable in clearinghouse or similar
next day funds; provided that if the Trustee receives a written request from any
Holder of Notes, the aggregate principal amount of which having the same
Interest Payment Date equals or exceeds $10,000,000, on or before the applicable
Regular Record Date for such Interest Payment Date, interest shall be paid by
wire transfer of immediately available funds to a bank located within the
continental United States and designated by such Holder in its request or by
direct deposit into the account of such Holder designated by such Holder in its
request if such account is maintained with the Trustee or any paying agent.

          (c)  The Trustee shall receive the Pledged First Mortgage Bonds or
Pledged Substituted Mortgage Bonds from the Company as provided in this
Indenture and shall hold the Pledged First Mortgage Bonds or Pledged Substituted
Mortgage Bonds, and any and all sums payable thereon or with respect thereto or
realized therefrom, in trust for the benefit of the Holders of the Notes, as
herein provided.  Subject to Article Eight hereof, the Company's obligations to
make payments with respect to the principal of, premium or interest on Pledged
First Mortgage Bonds or Pledged Substituted Mortgage Bonds will be fully or
partially, as the case may be, satisfied and discharged to the extent that, at
the time that any such payment shall be due, the then due principal of, premium
or interest on the related series of Notes shall have been fully or partially
paid or there shall have been deposited with the Trustee pursuant to this
Section 2.12 sufficient available funds to fully or partially pay the then due
principal of, premium, if any, or interest on such related series of Notes.

SECTION 2.13   NOTES ISSUABLE IN THE FORM OF A GLOBAL NOTE

          (a)  If the Company shall establish pursuant to Section 2.5 hereof
that the Notes of a particular series are to be issued in whole or in part in
the form of one or more Global Notes, then the Company shall execute and the
Trustee shall, in accordance with Section 2.5 hereof and the Company Order
delivered to the Trustee thereunder, authenticate and deliver such Global Note
or Notes, which (i) shall represent, shall be denominated in an amount equal to
the aggregate principal amount of, and shall have the same terms as, the
outstanding Notes to be represented by such Global Note or Notes, (ii) shall be
registered in the name of the Depository or its nominee, (iii) shall be
delivered by the Trustee to the Depository or pursuant to the Depository's
instruction and (iv) shall bear a legend substantially to the following effect:
"This Note is a Global Note registered in the name of the Depository (referred
to herein) or a nominee thereof and, unless and until it is exchanged in whole
or in part for the individual Notes represented hereby, this Global Note may not
be transferred except as a whole by the Depository to a nominee of the
Depository or by a nominee of the Depository to the Depository or another
nominee of the Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such successor Depository. Unless this
Global Note is presented by an authorized representative of The Depository Trust
Company, to the trustee for registration of transfer, exchange or payment, and
any certificate issued is registered in the name of Cede & Co. or such other
name as requested by an authorized representative of The Depository Trust
Company and any payment is made to Cede & Co., any transfer, pledge or other use
hereof for value or otherwise by or to any person is wrongful since the
registered owner hereof, Cede & Co., has an interest herein" or such other
legend as may be required by the rules and regulations of the Depository.

          (b)  Notwithstanding any other provision of Section 2.6 hereof or of
this Section 2.13, unless the terms of a Global Note expressly permit such
Global Note to be exchanged in whole or in part for individual Notes, a Global
Note may be transferred, in whole but not in part, only as described in the
legend thereto.

                                      -18-
<PAGE>
 
          (c)  (i)  If at any time the Depository for a Global Note notifies
the Company that it is unwilling or unable to continue as Depository for such
Global Note or if at any time the Depository for the Global Note shall no longer
be eligible or in good standing under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), or other applicable statute or regulation, the
Company shall appoint a successor Depository, with respect to such Global Note.
If a successor Depository for such Global Note is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
ineligibility, the Company's election pursuant to Section 2.5(c)(vii) hereof
shall no longer be effective with respect to the series of Notes evidenced by
such Global Note and the Company shall execute, and the Trustee, upon receipt of
a Company Order for the authentication and delivery of individual Notes of such
series in exchange for such Global Note, shall authenticate and deliver,
individual Notes of such series of like tenor and terms in definitive form in an
aggregate principal amount equal to the amount of the Global Note in exchange
for such Global Note. The Trustee shall not be charged with knowledge or notice
of the ineligibility of a Depository unless a responsible officer assigned to
and working in its corporate trustee administration department shall have actual
knowledge thereof.

               (ii)   The Company may at any time and in its sole discretion
determine that all (but not less than all) outstanding Notes of a series issued
or issuable in the form of one or more Global Notes shall no longer be
represented by such Global Note or Notes. In such event the Company shall
execute, and the Trustee, upon receipt of a Company Order for the authentication
and delivery of individual Notes in exchange for such Global Note, shall
authenticate and deliver individual Notes of like tenor and terms in definitive
form in an aggregate principal amount equal to the principal amount of such
Global Note or Notes in exchange for such Global Note or Notes.

               (iii)  In any exchange provided for in any of the preceding two
paragraphs, the Company will execute and the Trustee will authenticate and
deliver individual Notes in definitive registered form in authorized
denominations. Upon the exchange of a Global Note for individual Notes, such
Global Note shall be canceled by the Trustee. Notes issued in exchange for a
Global Note pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depository for such Global Note, pursuant
to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Notes to the Depository for
delivery to the persons in whose names such Notes are so registered, or if the
Depository shall refuse or be unable to deliver such Notes, the Trustee shall
deliver such Notes to the persons in whose names such Notes are registered,
unless otherwise agreed upon between the Trustee and the Company, in which event
the Company shall cause the Notes to be delivered to the persons in whose names
such Notes are registered.

          (d)  Neither the Company, the Trustee, any Authenticating Agent nor
any paying agent shall have any responsibility or liability for any aspect of
the records relating to, or payments made on account of beneficial ownership
interests of a Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

          (e)  Pursuant to the provisions of this subsection, at the option of
the Trustee and upon 30 days' written notice to the Depository but not prior to
the first Interest Payment Date of the respective Global Notes, the Depository
shall be required to surrender any two or more Global Notes which have identical
terms, including, without limitation, identical maturities, interest rates and
redemption provisions (but which may have differing Original Issue Dates) to the
Trustee, and the Company shall execute, and the Trustee shall authenticate and
deliver to, or at the direction of, the Depository, a Global Note in principal
amount equal to the aggregate principal amount of, and with all terms identical
to, the Global Notes surrendered thereto and that

                                      -19-
<PAGE>
 
shall indicate each applicable Original Issue Date and the principal amount
applicable to each such Original Issue Date. The exchange contemplated in this
subsection shall be consummated at least 30 days prior to any Interest Payment
Date applicable to any of the Global Notes surrendered to the Trustee. Upon any
exchange of any Global Note with two or more Original Issue Dates, whether
pursuant to this Section or pursuant to Section 2.6 or Section 3.3 hereof, the
aggregate principal amount of the Notes with a particular Original Issue Date
shall be the same before and after such exchange, after giving effect to any
retirement of Notes and the Original Issue Dates applicable to such Notes
occurring in connection with such exchange.

          (f)  Except as provided above, owners of beneficial interests in a
Global Note shall not be entitled to have Notes represented by such Global Note
registered in their names, shall not receive or be entitled to receive physical
delivery of Notes in certificated form and shall not be considered the Holders
thereof for any purpose under this Indenture.  Members of or participants in the
Depository shall have no rights under this Indenture with respect to any Global
Note held on their behalf by the Depository and such Depository may be treated
by the Company, the Trustee, and any agent of the Company or the Trustee as the
owner and Holder of such Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its members or participants, the
operation of customary practices governing the exercise of the rights of a
Holder of any Note, including, without limitation, the granting of proxies or
other authorization of participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action which a Holder
is entitled to give or take under this Indenture.

                              REDEMPTION OF NOTES
                                        
SECTION 3.1    APPLICABILITY OF ARTICLE

     Such of the Notes as are, by their terms, redeemable prior to their stated
maturity date at the option of the Company, may be redeemed by the Company at
such times, in such amounts and at such prices as may be specified therein and
in accordance with the provisions of this Article Three.

SECTION 3.2    NOTICE OF REDEMPTION; SELECTION OF NOTES

          (a)  The election of the Company to redeem any Notes shall be
evidenced by a Board Resolution or a Company Order which shall be given with
notice of redemption to the Trustee at least 45 days (or such shorter period
acceptable to the Trustee in its sole discretion) prior to the redemption date
specified in such notice.

          (b)  Following receipt of the Company's notice pursuant to Section
3.2(a) hereof, notice of redemption to each Holder of Notes to be redeemed as a
whole or in part shall be given by the Trustee, at the expense of the Company,
in the manner provided in Section 15.10 hereof, no less than 30 or more than 60
days prior to the date fixed for redemption.  Any notice which is given in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Noteholder receives the notice.  In any case, failure duly to
give such notice, or any defect in such notice, to the Holder of any Note
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any Note.

                                      -20-
<PAGE>
 
          (c)  Each such notice shall specify the date fixed for redemption, the
places of redemption and the redemption price at which such Notes are to be
redeemed, and shall state that payment of the redemption price of such Notes or
portion thereof to be redeemed will be made upon surrender of such Notes at such
places of redemption, that interest accrued to the date fixed for redemption
will be paid as specified in such notice, and that from and after such date
interest thereon shall cease to accrue.  If less than all of a series of Notes
having the same terms are to be redeemed, the notice shall specify the Notes or
portions thereof to be redeemed.  If any Note is to be redeemed in part only,
the notice which relates to such Note shall state the portion of the principal
amount thereof to be redeemed, and shall state that, upon surrender of such
Note, a new Note or Notes having the same terms in aggregate principal amount
equal to the unredeemed portion thereof will be issued.

          (d)  Unless otherwise provided by a supplemental indenture or Company
Order under Section 2.5 hereof, if less than all of a series of Notes having the
same terms are to be redeemed, the Trustee shall select pro rata or by lot, or
in such other manner as it shall deem appropriate and fair in its discretion the
particular Notes to be redeemed in whole or in part and shall thereafter
promptly notify the Company in writing of the Notes so to be redeemed.  If less
than all of a series of Notes represented by a Global Note are to be redeemed,
the particular Notes or portions thereof of such series to be redeemed shall be
selected by the Depository for such series of Notes in such manner as the
Depository shall determine.  Notes shall be redeemed only in denominations of
$1,000, provided that any remaining principal amount of a Note redeemed in part
shall be a denomination authorized under this Indenture.

          (e)  If at the time of the mailing of any notice of redemption the
Company shall not have irrevocably directed the Trustee to apply funds deposited
with the Trustee or held by it and available to be used for the redemption of
Notes to redeem all the Notes called for redemption, such notice, at the
election of the Company, may state that it is subject to the receipt of the
redemption moneys by the Trustee before the date fixed for redemption and that
such notice shall be of no effect unless such moneys are so received before such
date.

SECTION 3.3    PAYMENT OF NOTES ON REDEMPTION; DEPOSIT OF REDEMPTION PRICE

          (a)  If notice of redemption for any Notes shall have been given as
provided in Section 3.2 hereof and such notice shall not contain the language
permitted at the Company's option under Section 3.2(e) hereof, such Notes or
portions of Notes called for redemption shall become due and payable on the date
and at the places stated in such notice at the applicable redemption price,
together with interest accrued to the date fixed for redemption of such Notes.
Interest on the Notes or portions thereof so called for redemption shall cease
to accrue and such Notes or portions thereof shall be deemed not to be entitled
to any benefit under this Indenture except to receive payment of the redemption
price together with interest accrued thereon to the date fixed for redemption.
Upon presentation and surrender of such Notes at such a place of payment in such
notice specified, such Notes or the specified portions thereof shall be paid and
redeemed at the applicable redemption price, together with interest accrued
thereon to the date fixed for redemption.

          (b)  If notice of redemption shall have been given as provided in
Section 3.2 hereof and such notice shall contain the language permitted at the
Company's option under Section 3.2(e) hereof, such Notes or portions of Notes
called for redemption shall become due and payable on the date and at the places
stated in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption of such Notes, and interest on the
Notes or portions thereof so called for redemption shall cease to accrue and
such Notes or

                                      -21-
<PAGE>
 
portions thereof shall be deemed not to be entitled to any benefit under this
Indenture except to receive payment of the redemption price together with
interest accrued thereon to the date fixed for redemption; provided that, in
each case, the Company shall have deposited with the Trustee or a paying agent
on or prior to such redemption date an amount sufficient to pay the redemption
price together with interest accrued to the date fixed for redemption. Upon the
Company making such deposit and upon presentation and surrender of such Notes at
the place of payment in such notice specified, such Notes or the specified
portions thereof shall be paid and redeemed at the applicable redemption price,
together with interest accrued thereon to the date fixed for redemption. If the
Company shall not make such deposit on or prior to the redemption date, the
notice of redemption shall be of no force and effect and the principal on such
Notes or specified portions thereof shall continue to bear interest as if the
notice of redemption had not been given.

          (c)  No notice of redemption of Notes shall be mailed during the
continuance of any Event of Default, except (1) that, when notice of redemption
of any Notes has been mailed, the Company shall redeem such Notes but only if
funds sufficient for that purpose have prior to the occurrence of such Event of
Default been deposited with the Trustee or a paying agent for such purpose, and
(2) that notices of redemption of all outstanding Notes may be given during the
continuance of an Event of Default.

          (d)  Upon surrender of any Note redeemed in part only, the Company
shall execute, and the Trustee shall authenticate, deliver and register, a new
Note or Notes of authorized denominations in aggregate principal amount equal
to, and having the same terms, Original Issue Date or Dates and series as, the
unredeemed portion of the Note so surrendered.

SECTION 3.4    REDEMPTION OF FIRST MORTGAGE BONDS

     In the event that the First Mortgage Bonds securing any series of Notes
hereunder are redeemed in whole or in part by the Company pursuant to the terms
of such First Mortgage Bonds, the Trustee shall use the proceeds of such
redemption to redeem a like amount of the related series of Notes.  Any notice
of redemption of all or part of the First Mortgage Bonds delivered by the
Company to the Mortgage Trustee shall be deemed to be a notice of redemption
delivered to the Trustee pursuant to Section 3.2(a) hereof to redeem a like
amount of the related series of Notes.

cash, (B) U.S. Government Obligations maturing as to principal and interest in
such amounts and at such times as will insure the availability of cash, or (C) a
combination of cash and U.S. Government Obligations, in any case sufficient,
without reinvestment, as certified by an independent public accounting firm of
national reputation in a written certification delivered to the Trustee, to pay
at maturity or the applicable redemption date (provided that notice of
redemption shall have been duly given or irrevocable provision satisfactory to
the Trustee shall have been duly made for the giving of any notice of
redemption) any outstanding Note, including principal and any premium and
interest due or to become due to such date of maturity, as the case may be,
such Note shall cease to be entitled to any lien, benefit or security under this
Indenture and this Indenture will cease to be of further effect with respect to
such Note.  Upon a Note ceasing to be entitled to any lien, benefit or security
under this Indenture, the obligation of the Company to make payment with respect
to principal of and premium, if any, and interest on a principal amount of the
related series of Pledged First Mortgage Bonds or the related series of Pledged
Substituted Mortgage Bonds equal to the principal amount of such Note shall be
satisfied and discharged and such portion of the principal amount of such
Pledged First Mortgage Bonds or Pledged Substituted Mortgage Bonds shall cease
to secure the Notes in any manner.

SECTION 5.2    DEPOSITED MONEYS TO BE HELD IN TRUST BY TRUSTEE

     All moneys and U.S. Government Obligations deposited with the Trustee
pursuant to Section 5.1 hereof shall be held in trust and applied by it to the
payment, either directly or through any paying agent (including the Company if
acting as its own paying agent), to the Holders of the particular Notes for the
payment or redemption of which such moneys and U.S. Government Obligations have
been deposited with the Trustee of all sums due and to become due thereon for
principal and premium, if any, and interest.

SECTION 5.3    PAYING AGENT TO REPAY MONEYS HELD

     Upon the satisfaction and discharge of this Indenture all moneys then held
by any paying agent for the Notes (other than the Trustee) shall, upon written
demand by an Authorized Agent, be repaid to the Company or paid to the Trustee,
and thereupon such paying agent shall be released from all further liability
with respect to such moneys.

SECTION 5.4    RETURN OF UNCLAIMED MONEYS

     Any moneys deposited with or paid to the Trustee for payment of the
principal of or any premium or interest on any Notes and not applied but
remaining unclaimed by the Holders of such Notes for one year after the date
upon which the principal of or any premium or interest on such Notes, as the
case may be, shall have become due and payable, shall be repaid to the Company
by the Trustee on written demand by an Authorized Agent, and all liability of
the Trustee shall thereupon cease; and any Holder of any of such Notes shall
thereafter look only to the Company for any payment which such Holder may be
entitled to collect.

SECTION 6.1    PAYMENT OF PRINCIPAL PREMIUM AND INTEREST

     The Company covenants and agrees for the benefit of the Holders of each
series of Notes that it will duly and punctually pay or cause to be paid the

and for exchange as in this Indenture provided, and where, at any time when the
Company is obligated to make a payment of principal and premium upon Notes, the
Notes may be surrendered for payment, and may maintain at any such office or
agency and at its principal office an office or agency where notices and demands
to or upon the Company in respect of the Notes or of this Indenture may be
served.  The Company will give to the Trustee written notice of the location of
each such office or agency and of any change of location thereof.  If the

SECTION 6.4    PROVISION AS TO PAYING AGENT

     The Trustee shall be the paying agent for the Notes and, at the option of
the Company, the Company may appoint additional paying agents (including without

agent, it shall cause such paying agent to execute and deliver to the Trustee an
instrument in which such agent shall agree with the Trustee, subject to this
Section 6.4:

          (1)  that it will hold in trust for the benefit of the Holders and the
Trustee all sums held by it as such agent for the payment of the principal of
and any premium or interest on the Notes (whether such sums have been paid to it
by the Company or by any other obligor on such Notes) in trust for the benefit
of the Holders of such Notes;

          (2)  that it will give to the Trustee notice of any failure by the
Company (or by any other obligor on such Notes) to make any payment of the
principal of and any premium or interest on such Notes when the same shall be
due and payable; and

          (3)  that it will at any time during the continuance of any such
failure, upon the written request of the Trustee, forthwith pay to the Trustee
all sums so held in trust by such paying agent.

     If the Company shall act as its own paying agent with respect to any Notes,
it will, on or before each due date of the principal of and any premium or
interest on such Notes, set aside, segregate and hold in trust for the benefit
of the Holders of such Notes a sum sufficient to pay

                                      -29-
<PAGE>
 
such principal and any premium or interest so becoming due and will notify the
Trustee of any failure by it to take such action and of any failure by the
Company (or by any other obligor on such Notes) to make any payment of the
principal of and any premium or interest on such Notes when the same shall
become due and payable.

any, on any Notes, deposit with such paying agent a sum sufficient to pay the
principal (and premium, if any) or interest, if any, so becoming due, such sum
to be held in trust for the benefit of the Persons entitled to such principal,
premium or interest, if any, and (unless such paying agent is the Trustee) the
Company shall promptly notify the Trustee of any failure on its part to so act.

     Anything in this Section 6.4 to the contrary notwithstanding, the Company
may, at any time, for the purpose of obtaining a satisfaction and discharge of
this Indenture, or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust by it or any paying agent hereunder, as required by this
Section 6.4, such sums to be held by the Trustee upon the trusts herein
contained.

     Anything in this Section 6.4 to the contrary notwithstanding, the agreement
to hold sums in trust as provided in this Section 6.4 is subject to Sections 5.3
and 5.4 hereof.

SECTION 6.5    OPINIONS OF COUNSEL

     The Company will cause this Indenture, any indentures supplemental to this
Indenture, and any financing or continuation statements to be promptly recorded
and filed and re-recorded and refiled in such manner and in such places, as may
be required by law in order fully to preserve, protect and perfect the security
of the Noteholders and all rights of the Trustee, and shall deliver to the
Trustee:

          (a)  promptly after the execution and delivery of this Indenture and
of any indenture supplemental to this Indenture, an Opinion of Counsel either
stating that, in the opinion of such counsel, this Indenture or such
supplemental indenture and any financing or continuation statements have been

of the Trustee intended to be created by this Indenture for the benefit of the
Holders from time to time of the Notes in the Pledged First Mortgage Bonds or
the Pledged Substituted Mortgage Bonds, and reciting the details of such action,
or stating that, in the opinion of such counsel, no such action is necessary to
perfect or make such interest effective and stating what, if any, action of the
foregoing character may reasonably be expected to become necessary prior to the
next succeeding October 1 to maintain, perfect and make such interest effective;
and

          (b)  on or before October 1 of each year, beginning in 1999, and prior
to the Substitution Date, an Opinion of Counsel either stating that in the
opinion of such counsel such action has been taken, since the date of the most
recent Opinion of Counsel furnished pursuant to this Section 6.5(b) or the first
Opinion of Counsel furnished pursuant to Section 6.5(a) hereof, with respect to
the recording, filing, re-recording, or refiling of this Indenture, each
supplemental indenture and any financing or continuation statements, as is
necessary to maintain and perfect the interest of the Trustee intended to be
created by this Indenture for the benefit of the Holders from time to time of
the Notes in the Pledged First Mortgage Bonds or the Pledged Substituted
Mortgage Bonds, and reciting the details of such action, or stating that in the

SECTION 6.6    CERTIFICATES AND NOTICE TO TRUSTEE

     The Company shall, on or before October 1 of each year, beginning in 1999,
deliver to the Trustee a certificate from its principal executive officer,
principal financial officer or principal accounting officer covering the
preceding calendar year and stating whether or not, to the knowledge of such
party, the Company has complied with all conditions and covenants under this
Indenture, and, if not, describing in reasonable detail any failure by the
Company to comply with any such conditions or covenants.  For purposes of this
Section, compliance shall be determined without regard to any period of grace or
requirement of notice provided under this Indenture.

SECTION 6.7    NEGATIVE COVENANTS

     On and after the Substitution Date, if and only if no Pledged Substituted
Mortgage Bonds have been delivered to the Trustee, the Company will not create,
assume, incur or suffer to exist any Mortgage upon any Principal Property,
whether owned or leased on the Substitution Date or thereafter acquired, to
secure any Debt of the Company or any other Person (other than the Notes),
without in any such case making effective provision whereby all of the Notes
outstanding hereunder (other than such Notes, if any, which shall by their terms
be expressly excluded from the operation of this Section 6.7) shall be directly
secured equally and ratably with such Debt, excluding, however, from the
operation of the foregoing provisions:

               (i)    any Mortgage upon property existing at the time of
acquisition thereof including acquisition by means of merger or consolidation
(but excluding any extension thereof or addition thereto unless the terms of the
Mortgage as of the date of the acquisition of such property provide that such
Mortgage shall be secured by such extensions or additions);

               (ii)   any Mortgage to secure the payment of all or any part of
the purchase price of property or to secure any Debt incurred prior to, at the
time of or within 180 days after the acquisition of such property for the
purpose of financing all or any part of the purchase price thereof;

               (iii)  any Mortgage existing at the Substitution Date;

               (iv)   any Permitted Encumbrance; and

               (v)    any extension, refinancing, renewal of replacement (or
successive extensions refinancings, renewals or replacements) in whole or in
part of any Mortgage referred to in any of the foregoing clauses (i) to (iv),
inclusive; provided, however, that the principal amount of Debt secured thereby
shall not exceed the principal amount of Debt (plus any premium or fee payable
in connection with such extension, refinancing, renewal or replacement) so
secured at the time of such extension, refinancing, renewal or replacement; and
provided, further, that such Mortgage shall be limited to all or such part of
the property which was subject to the Mortgage so extended, refinanced, renewed
or replaced (plus improvements on such property).

     Notwithstanding the foregoing provisions of this Section 6.7, the Company
may create, assume, incur or suffer to exist any Mortgage upon any Principal
Property which is not excepted by any of clauses (i) through (v) above without
equally and ratably securing the Notes, provided that the aggregate amount of
all Debt then outstanding secured by such Mortgage and all similar Mortgages,
does not exceed 15% of the total consolidated capitalization of the Company as
shown on the audited consolidated balance sheet contained in the latest annual
report of the Company filed with the SEC.  For the purposes of this Section 6.7,
any Mortgage in favor of the United States of America or any States thereof, or
any other country, or any political subdivision

                                      -31-
<PAGE>
 
of any of the foregoing, to secure partial, progress, advance or other payments
pursuant to the provisions of any contract or statute, or any Mortgage securing
industrial development, pollution control or similar revenue bonds shall not be
deemed to create a Mortgage to secure any Debt.

          NOTEHOLDER LISTS AND REPORTS BY THE COMPANY AND THE TRUSTEE
                                        
SECTION 7.1    NOTEHOLDER LISTS

          (a)  The Company shall furnish or cause to be furnished to the Trustee
semiannually, not later than 15 days after each Regular Record Date for each
Interest Payment Date that is not a maturity date and at such other times as
such Trustee may request in writing, within 30 days after receipt by the Company
of any such request, a list in such form as the Trustee may reasonably require
containing all the information in the possession or control of the Company, or
any paying agents other than the Trustee, as to the names and addresses of the
Holders of Notes, obtained since the date as of which the next previous list, if
any, was furnished.  Any such list may be dated as of a date not more than 15
days prior to the time such information is furnished or caused to be furnished
and need not include information received after such date; provided that as long
as the Trustee is the registrar for the Notes, no such list shall be required to
be furnished.  The Trustee shall preserve any list provided to it pursuant to
this Section until such time as the Company or any paying agent, as applicable,
shall provide it with a more recent list.

          (b)  Within five Business Days after the receipt by the Trustee of a
written application by any three or more Holders stating that the applicants
desire to communicate with other Holders with respect to their rights under the
Indenture or under the Notes, and accompanied by a copy of the form of proxy or
other communication which such applicants propose to transmit, and by reasonable
proof that each such applicant has owned a Note for a period of at least six
months preceding the date of such application, the Trustee shall, at its
election, either:

               (i)  afford to such applicants access to all information
furnished to or received by the Trustee pursuant to Section 7.1(a) hereof or, if
applicable, in its capacity as registrar for the Notes; or

               (ii) inform such applicants as to the approximate number of
Holders according to the most recent information furnished to or received by the
Trustee under Section 7.1(a) hereof or if applicable in its capacity as
registrar for the Notes, and as to the approximate cost of mailing to such
Holders the form of proxy or other communication, if any, specified in such
application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of Notes a copy of the form of proxy or other communication
which is specified in such request, with reasonable promptness after a tender to
the Trustee of the material to be mailed and of payment, or provision for the
payment, of the reasonable expenses of such mailing, unless within five days
after such tender the Trustee shall mail to such applicants and file with the
SEC, together with a copy of the material to be mailed, a written statement to
the effect that, in the opinion of the Trustee, such mailing would be contrary
to the best interests of the Holders or would be in violation of applicable law.
Such written statement shall specify the basis of such opinion.  If the SEC,
after

                                      -32-
<PAGE>
 
opportunity for a hearing upon the objections specified in the written statement
so filed, shall enter an order refusing to sustain any of such objections or
after the entry of an order sustaining one or more of such objections, the SEC
shall find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

          (c)  Every Holder of a Note, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any paying agent nor any Authenticating Agent shall be held accountable by
reason of the disclosure of any such information as to the names and addresses
of the Holders in accordance with this Section, regardless of the source from
which such information was derived, and that the Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
this Section.

prescribe) which the Company may be required to file with the SEC pursuant to
Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not

if required by such rules and regulations, certificates or opinions of
independent public accountants, conforming to the requirements of Section 15.5
hereof, as to compliance with conditions or covenants, compliance with which is
subject to verification by accountants; and

          (b)  The Trustee shall from time to time transmit by mail brief
reports that comply, both in content and date of delivery, with Section 313(b)

                          REMEDIES OF THE TRUSTEE AND
                       NOTEHOLDERS ON EVENTS OF DEFAULT

occurred and is 

                                      -34-
<PAGE>
 
continuing, and the Mortgage Trustee or Holders of at least a majority in
aggregate principal amount of the Notes at the time outstanding shall have given
written notice thereof to the Trustee;

               (5)  if any Pledged Substituted Mortgage Bonds are outstanding, a

               (6)  the entry of a decree or order by a court having
jurisdiction over the Company for relief in respect of the Company under the
United States Bankruptcy Code, 11 U.S.C. (S) 101-1330, as now constituted or
hereafter amended (the "Bankruptcy Code"), or any other applicable federal or
state bankruptcy, insolvency or other similar law, or appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or similar official of
the Company or of any substantial part of its property, or ordering the winding
up or liquidation of its affairs, and the continuance of any such decree or

become due, or the taking of corporate action by the Company to effectuate any
such action;

then and in each and every such case other than an Event of Default specified in
Section 8.1(4) or 8.1(5), either the Trustee or the Holders of a majority in
aggregate principal amount of the Notes of such series then outstanding, by
notice in writing to the company (and to the Trustee if given by Noteholders)
may declare the principal of all of the Notes of such series to be due and
payable immediately and upon any such declaration the same shall become and
shall be immediately due and payable, notwithstanding anything to the contrary
contained in this Indenture or in the Notes of such series; provided, however,
that if, at any time after the principal of the Notes of such series shall have
been so declared due and payable and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided and prior to the mailing to the Trustee by the Mortgage Trustee of a
firm, valid and unconditional notice to the Trustee of the acceleration of all
of the first mortgage bonds issued and outstanding under either the First
Mortgage or the Substituted Mortgage, as applicable, the Company shall pay or
shall deposit with the Trustee a sum of money sufficient to pay (i) all matured
installments of interest upon all of the Notes of such series, (ii) the
principal of and any premium on all Notes of such series which shall have become
due otherwise than by acceleration (with interest on overdue installments of
interest, to the extent that payment of such interest is enforceable under
applicable law, and on such principal and applicable premium at the rate borne
by the Notes to the date of such payment or deposit), (iii) all sums paid or
advanced by the Trustee hereunder, and (iv) the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 9.6, and if any and all defaults
under this Indenture, other than the non-payment of principal of and interest
and premium, if any, on the Notes of such series which shall have become due
solely by such declaration of acceleration, shall have been cured or waived
(including any defaults under either the First Mortgage or the Substituted
Mortgage, as applicable, as evidenced by notice thereof from the Mortgage
Trustee to the Trustee), then and in every such case the Holders of a majority
in aggregate principal amount of the Notes of such series then outstanding may,
by written notice to 

                                      -35-
<PAGE>
 
the Company and the Trustee, waive all such defaults and rescind and annul such
declaration of acceleration and its consequences; provided, however, that no
such waiver or rescission and annulment shall extend to or shall affect any
subsequent default, or shall impair any right consequent thereon. If an Event of
Default specified in either Section 8.1(4) or Section 8.1(5) occurs, the
principal of all of the Notes, together with interest accrued thereon, shall
become due and payable immediately with respect thereto, without the necessity
of any action by the Trustee or any Noteholder; provided, however, that a
rescission and annulment of the declaration that the first mortgage bonds
outstanding under either the First Mortgage or the Substituted Mortgage, as
applicable, be due and payable prior to their stated maturities shall constitute
a waiver of the Event of Default under Section 8.1(4) or Section 8.1(5) and of
its consequences, but no such waiver shall extend to or affect any subsequent
Event of Default under Section 8.1(4) or Section 8.1(5).

          (b)  If the Trustee shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
because of such rescission or annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company and the Trustee shall be restored respectively to their several
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceeding had been

or in the case of any similar judicial proceedings relative to the Company or
other obligor on the Notes, or to the creditors or property of the Company or
such other obligor, the Trustee, irrespective of whether the principal of the

any of the Notes, may be enforced by the Trustee without the possession of any
of the Notes, or the production thereof in any trial or other proceeding
relative thereto, and any such suit or proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall be for the ratable benefit of the Holders of the
Notes in respect of which such action was taken.

          (c)  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or to accept or adopt on behalf of any
Noteholder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any

amount available is not sufficient to pay in full all Notes due on any
particular date, then to the payment thereof ratably, according to the amounts

availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such Holder previously shall have given to the Trustee written
notice of an Event of Default with respect to such Note and of the continuance
thereof, as hereinabove provided, and unless also Noteholders of a majority in
aggregate principal amount of the Notes then outstanding affected by such Event
of Default shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder 

                                      -37-
<PAGE>
 
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding.

          (b)  Notwithstanding any other provision in this Indenture, however,
the rights of any Holder of any Note to receive payment of the principal of and
any premium and interest on such Note, on or after the respective due dates
expressed in such Note or on the applicable redemption date, or to institute
suit for the enforcement of any such payment on or after such respective dates
shall not be impaired or affected without the consent of such Holder.

SECTION 8.5    PROCEEDINGS BY TRUSTEE

     In case of an Event of Default hereunder the Trustee may in its discretion
proceed to protect and enforce the rights vested in it by this Indenture,
including its rights as holder of the Pledged First Mortgage Bonds or the
Pledged Substituted Mortgage Bonds, by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted to it
under this Indenture, or to enforce any other legal or equitable right vested in
the Trustee by this Indenture or by law.

SECTION 8.6    REMEDIES CUMULATIVE AND CONTINUING

     All powers and remedies given by this Article Eight to the Trustee or to
the Noteholders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any powers and remedies hereof or of any other powers and
remedies available to the Trustee or the Holders of the Notes, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture, and no delay or omission
of the Trustee or of any Holder of any of the Notes in exercising any right or
power accruing upon any default occurring and continuing as aforesaid shall
impair any such right or power, or shall be construed to be a waiver of any such
default or an acquiescence therein; and, subject to Section 8.4 hereof, every
power and remedy given by this Article Eight or by law to the Trustee or to the
Noteholders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

SECTION 8.7    DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF
               NOTEHOLDERS

     The Holders of a majority in aggregate principal amount of the Notes at the
time outstanding shall have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee; provided, that (subject to Section
9.1 hereof) the Trustee shall have the right to decline to follow any such
direction if the Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith
by its board of directors or trustees, executive committee, or a trust committee
of directors or trustees or responsible officers shall determine that the action
or proceeding so directed would involve the Trustee in personal liability or
would be unduly prejudicial to the rights of Noteholders not joining in such
directions.  The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may on behalf of all of the Holders of the Notes
waive any past default or Event of Default hereunder and its consequences except
a default in the payment of principal of or any premium or interest on the
Notes.  Upon any such waiver the Company, the Trustee and the 

                                      -38-
<PAGE>
 
Holders of the Notes shall be restored to their former positions and rights
hereunder, respectively, but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.
Whenever any default or Event of Default hereunder shall have been waived as
permitted by this Section 8.7, said default or Event of Default shall for all
purposes of the Notes and this Indenture be deemed to have been cured and to be
not continuing.

SECTION 8.8    NOTICE OF DEFAULT

     The Trustee shall within 90 days after the occurrence of a default known to
it, give to all Holders of the Notes, in the manner provided in Section 15.10
hereof, notice of such default, unless such default shall have been cured before
the giving of such notice, the term "default" for the purpose of this Section
8.8 being hereby defined to be any event which is or after notice or lapse of
time or both would become an Event of Default; provided that, except in the case
of default in the payment of the principal of or any premium or interest on any
of the Notes, or in the payment of any sinking or purchase fund installments,
the Trustee shall be protected in withholding such notice if and so long as its
board of directors or trustees, executive committee, or a trust committee of
directors or trustees or responsible officers in good faith determines that the
withholding of such notice is in the interests of the Holders of the Notes.  The
Trustee shall not be charged with knowledge of any Event of Default unless a
responsible officer of the Trustee assigned to the corporate trustee department
of the Trustee shall have actual knowledge of such Event of Default.

SECTION 8.9    UNDERTAKING TO PAY COSTS

     All parties to this Indenture agree, and each Holder of any Note by
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but this
Section 8.9 shall not apply to any suit instituted by the Trustee, or to any
suit instituted by any Noteholder, or group of Noteholders, holding in the
aggregate more than 10% in principal amount of the Notes outstanding, or to any
suit instituted by any Noteholder for the enforcement of the payment of the
principal of or any premium or interest on any Note on or after the due date
expressed in such Note or the applicable redemption date.

after the curing of all Events of Default which may have occurred, undertakes to
perform such duties and only such duties as are specifically set forth in this
Indenture.  If an Event of Default has occurred (which has not been cured or
waived), the Trustee shall exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

                                      -39-

the curing or waiving of all Events of Default which may have occurred

                    (A)  the duties and obligations of the Trustee shall be
determined solely by the express provisions of this Indenture, and the Trustee
shall not be liable except for the performance of such duties and obligations as
are specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

                    (B)  in the absence of bad faith on the part of the Trustee,
the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon any certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;
but, in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall be under a duty to examine the same to determine whether or not they
conform to the requirements of this Indenture as to form;

               (2)  the Trustee shall not be liable for any error of judgment
made in good faith by a responsible officer or officers of the Trustee, unless
it shall be proved that the Trustee was negligent in ascertaining the pertinent
facts; and

               (3)  the Trustee shall not be liable with respect to any action
taken or omitted to be taken by it in good faith in accordance with Section 8.7
hereof relating to the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee under this Indenture.

SECTION 9.2    RELIANCE ON DOCUMENTS, OPINIONS, ETC.

     Except as otherwise provided in Section 9.1 hereof:

          (a)  the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, note or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

          (b)  any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof is herein specifically prescribed); and any Board
Resolution may be evidenced to the Trustee by a copy thereof certified by the
Secretary or an Assistant Secretary of the Company;

          (c)  the Trustee may consult with counsel and any advice or Opinion of
Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
accordance with such advice or Opinion of Counsel;

          (d)  the Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request, order or
direction of any of the Noteholders, pursuant to this Indenture, unless such
Noteholders shall have offered to the Trustee reasonable 

                                      -40-
<PAGE>
 
security or indemnity against the costs, expenses and liabilities which may be

resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, note or other paper or document, unless
requested in writing to do so by the Holders of at least a majority in principal
amount of the then outstanding Notes; provided that if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
this Indenture, the Trustee may require reasonable indemnity against such
expense or liability as a condition to so proceeding;

          (g)  no provision of this Indenture shall require the Trustee to
extend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it; and

          (h)  the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or through agents or attorneys;
provided that the Trustee shall not be liable for the conduct or acts of any
such agent or attorney that shall have been appointed in accordance herewith
with due care.

of the Notes.  The Trustee shall not be accountable for the use or application
by the Company of any Notes or the proceeds of any Notes authenticated and
delivered by the Trustee in conformity with this Indenture.  The Trustee shall
not be responsible for recording or filing this Indenture, any supplemental
indenture, or any financing or continuation statement in any public office at

the extent required by law.  The Trustee may 

                                      -41-

allow and credit to the Company interest on any money received hereunder at such
rate, if any, as may be agreed upon by the Company and the Trustee from time to
time as may be permitted by law.

SECTION 9.6    COMPENSATION AND EXPENSES OF TRUSTEE

     The Company covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, reasonable compensation (which shall not
be limited by any law in regard to the compensation of a trustee of an express
trust), and the Company shall pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with this Indenture (including the reasonable compensation
and the reasonable expenses and disbursements of its counsel and agents,
including any Authenticating Agents, and of all persons not regularly in its
employ) except any such expense, disbursement or advance as may arise from its
negligence or bad faith.  The Company also covenants to indemnify the Trustee
for, and to hold it harmless against, any loss, liability or expense incurred
without negligence or bad faith on the part of the Trustee and arising out of or
in connection with the acceptance or administration of this trust, including the
costs and expenses of defending itself against any claim or liability.  The
obligations of the Company under this Section 9.6 to compensate the Trustee and
to pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder.  Such additional indebtedness

necessary or desirable that a matter be proved or established prior to the
taking, suffering or omitting of any action hereunder, such matter (unless other
evidence in respect thereof is herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee, and such Officers' Certificate, in the absence of negligence or bad
faith on the part of the Trustee, shall be full warrant to the Trustee for any
action taken, suffered or omitted by it under this Indenture in reliance
thereon.

SECTION 9.8    CONFLICTING INTEREST OF TRUSTEE

     The Trustee shall be subject to and shall comply with the provisions of
Section 310 of the TIA; provided that, to the extent permitted by law, The Bank
of New York shall not be deemed to have a conflicting interest for purposes of
Section 310(b) of the TIA because of its capacity as trustee under the First
Mortgage or the Substituted Mortgage. Nothing in this Indenture shall be
deemed to prohibit the Trustee or the Company from making any application
permitted pursuant to such section.

SECTION 9.9    EXISTENCE AND ELIGIBILITY OF TRUSTEE

     There shall at all times be a Trustee hereunder which Trustee shall at all
times be a corporation organized and doing business under the laws of the United

published. No obligor upon the Notes or Person directly or indirectly
controlling, controlled by, or under common control with such obligor shall
serve as Trustee. If at any time the Trustee shall cease to be eligible in
accordance with this Section 9.9, the Trustee shall resign immediately in the
manner and with the effect specified in Section 9.10 hereof.

day.

          (b)  Any Trustee may be removed at any time by an instrument or
concurrent instruments in writing filed with such Trustee and signed and

accordance with Section 9.9 hereof and shall fail to resign after written
request therefor by the Company or by any Holder who has been a bona fide Holder
for at least six months, (2) the Trustee shall fail to comply with Section 9.8
hereof after written request therefor by the Company or any such Holder, or (3)
the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or its property shall be appointed or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Trustee may be removed forthwith by an instrument or concurrent instruments in
writing filed with the Trustee and either:  (1)  signed by the President, any
Vice President, the Treasurer or any Assistant Treasurer of the Company and

any Noteholder or the resigning Trustee may apply to any court of competent
jurisdiction to appoint a successor Trustee. Said court may thereupon after such
notice, if any, as such court may deem proper and prescribe, appoint a successor
Trustee.

Trustee shall be a bank or trust company eligible under Section 9.9 hereof and
qualified under Section 9.8 hereof.

          (a)  Any successor Trustee appointed as provided in Section 9.11
hereof shall execute, acknowledge and deliver to the Company and to its
predecessor Trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Trustee herein; but nevertheless, on the written request of the Company
or of the successor Trustee, the Trustee ceasing to act shall, upon payment of
any amounts then due it pursuant to Section 9.6 hereof execute and deliver an
instrument transferring to such successor Trustee all the rights and powers of

by such Trustee to secure any amounts then due it pursuant to Section 9.6
hereof.

          (c)  Upon acceptance of appointment by a successor Trustee as provided
in this Section 9.12, the successor Trustee shall mail notice of its succession
hereunder to all Holders of Notes as the names and addresses of such Holders
appear on the registry books.

SECTION 9.13   SUCCESSION BY MERGER, ETC.

          (a)  Any corporation into which the Trustee may be merged or with
which it may be consolidated, or any corporation resulting from any merger or

succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder without the execution
or filing of any paper or any further act on the part of any of the parties
hereto, provided such corporation shall be otherwise qualified and eligible
under this Article.

          (b)  If at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor Trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been
authenticated, any successor to the Trustee may authenticate such Notes either
in the name of any predecessor hereunder or in the name of the successor
Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Notes or in this Indenture provided that the certificates
of the Trustee shall have; provided that the right to adopt the certificate of

Trustee with the written consent of the Company, with power to act on its behalf
and subject to the direction of the Trustee in the authentication and delivery
of Notes in connection with transfers and exchanges under Sections 2.6, 2.7,
2.8, 2.13, 3.3, and 13.4 hereof as fully to all intents and purposes as though
such Authenticating Agents had been expressly authorized by those Sections to
authenticate and deliver Notes. For all purposes of this Indenture, the
authentication and delivery of Notes by any Authenticating Agent pursuant to
this Section 9.15 shall be deemed to be the authentication and delivery of such
Notes "by the Trustee." Any such Authenticating Agent shall be a bank or trust
company or other Person of the character and qualifications set forth in Section
9.9 hereof.

          (b)  Any corporation into which any Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 9.15, without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent or such successor
corporation.

          (c)  Any Authenticating Agent may at any time resign by giving written
notice of resignation to the Trustee and to the Company.  The Trustee may at any
time terminate the agency of any Authenticating Agent by giving written notice
of termination to such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
any Authenticating Agent shall cease to be eligible under this Section 9.15, the
Trustee may, with the written consent of the Company, appoint a successor
Authenticating Agent, and upon so doing shall give written notice of such
appointment to the Company and shall mail, in the manner provided in Section
15.10, notice of such appointment to the Holders of Notes.

          (d)  The Company agrees to pay to each Authenticating Agent from time
to time reasonable compensation for its services.

          (e)  Sections 9.2, 9.3, 9.6, 9.7 and 9.9 hereof shall be applicable to
any Authenticating Agent.

                          CONCERNING THE NOTEHOLDERS
                                        
SECTION 10.1   ACTION BY NOTEHOLDERS

     Whenever in this Indenture it is provided that the Holders of a specified
percentage in aggregate principal amount of the Notes may take any action, the
fact that at the time of taking any such action the Holders of such specified
percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by such Noteholders in person or
by agent or proxy appointed in writing, (b) by the record of such Noteholders
voting in favor thereof at any meeting of Noteholders duly called and held in
accordance with Article 

                                      -45-
<PAGE>
 
Eleven hereof or (c) by a combination of such instrument or instruments and any
such record of such a meeting of Noteholders.

SECTION 10.2   PROOF OF EXECUTION BY NOTEHOLDERS

          (a)  Subject to Sections 9.1, 9.2 and 11.5 hereof, proof of the
execution of any instruments by a Noteholder or the agent or proxy for such
Noteholder shall be sufficient if made in accordance with such reasonable rules
and regulations as may be prescribed by the Trustee or in such manner as shall
be satisfactory to the Trustee.  The ownership of Notes shall be proved by the
register for the Notes maintained by the Trustee.

          (b)  The record of any Noteholders' meeting shall be proven in the
manner provided in Section 11.6 hereof.

SECTION 10.3   WHO DEEMED ABSOLUTE OWNERS

     Subject to Sections 2.4(f) and 10.1 hereof, the Company, the Trustee, any
paying agent and any Authenticating Agent shall deem the person in whose name
any Note shall be registered upon the register for the Notes to be, and shall
treat such person as, the absolute owner of such Note (whether or not such Note
shall be overdue) for the purpose of receiving payment of or on account of the
principal and premium, if any, and interest on such Note, and for all other
purposes; and neither the Company nor the Trustee nor any paying agent nor any
Authenticating Agent shall be affected by any notice to the contrary.  All such
payments shall be valid and effectual to satisfy and discharge the liability
upon any such Note to the extent of the sum or sums so paid.

SECTION 10.4   COMPANY-OWNED NOTES DISREGARDED

     In determining whether the Holders of the requisite aggregate principal
amount of outstanding Notes have concurred in any direction, consent or waiver
under this Indenture, Notes which are owned by the Company or any other obligor
on the Notes or by any person directly or indirectly controlling or controlled
by or under direct or indirect common control with the Company or any other
obligor on the Notes shall be disregarded and deemed not to be outstanding for
the purpose of any such determination; provided that, for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, consent or waiver, only Notes which the Trustee knows are so owned
shall be so disregarded.  Notes so owned which have been pledged in good faith
to third parties may be regarded as outstanding for the purposes of this Section
10.4 if the pledgee shall establish to the satisfaction of the Trustee the
pledgee's right to take action with respect to such Notes and that the pledgee
is not a person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor.
In the case of a dispute as to such right, any decision by the Trustee taken
upon the advice of counsel shall be full protection to the Trustee.

SECTION 10.5   REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND

     Except as may be otherwise required in the case of a Global Note by the
applicable rules and regulations of the Depository, at any time prior to the
taking of any action by the Holders of the percentage in aggregate principal
amount of the Notes specified in this Indenture in connection with such action,
any Holder of a Note, which has been included in the Notes the Holders of which
have consented to such action may, by filing written notice with the Trustee at
the corporate trust office of the Trustee and upon proof of ownership as
provided in Section 10.2(a) hereof, revoke such action so far as it concerns
such Note.  Except as aforesaid any such 

                                      -46-
<PAGE>
 
action taken by the Holder of any Note shall be conclusive and binding upon such
Holder and upon all future Holders and owners of such Note and of any Notes
issued in exchange, substitution or upon registration of transfer therefor,
irrespective of whether or not any notation thereof is made upon such Note or
such other Notes.

SECTION 10.6   RECORD DATE FOR NOTEHOLDER ACTS

     If the Company shall solicit from the Noteholders any request, demand,
authorization, direction, notice, consent, waiver or other act, the Company may,
at its option, by Board Resolution, fix in advance a record date for the
determination of Noteholders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other act, but the Company
shall have no obligation to do so.  If such a record date is fixed, such
request, demand, authorization, direction, notice, consent, waiver or other act
may be given before or after the record date, but only the Noteholders of record
at the close of business on the record date shall be deemed to be Noteholders
for the purpose of determining whether Holders of the requisite aggregate
principal amount of outstanding Notes have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
act, and for that purpose the outstanding Notes shall be computed as of the
record date; provided that no such request, demand, authorization, direction,
notice, consent, waiver or other act by the Noteholders on the record date shall
be deemed effective unless it shall become effective pursuant to this Indenture
not later than six months after the record date.

     SOUTH JERSEY GAS COMPANY, a corporation of the state of New Jersey (the
"Company"), for value received hereby promises to pay to Cede & Co. or
registered assigns, the principal sum of   DOLLARS on the Maturity Date set
forth above, and to pay interest thereon from the Original Issue Date (or if
this Global Note has two or more Original Issue Dates, interest shall, beginning

___________ or ____________, as the case may be, next preceding such Interest
Payment Date; provided that the first Interest Payment Date for any part of this
Note, the Original Issue Date of which is after a Regular Record Date but prior
to the applicable Interest Payment Date, shall be the Interest Payment Date
following the next succeeding Regular Record Date; and provided that interest
payable on the Maturity Date set forth above or, if applicable, upon redemption

Person in whose name this Note is registered at the close of business on a
Special Record Date for the payment of such defaulted interest to be fixed by
the Trustee, notice whereof shall be given to Noteholders not more than 15 days
or fewer than 10 days prior to such Special Record Date. On or before
__________, New York City time, or such other time as shall be agreed upon
between the Trustee and the Depository, of the day on which such payment of
interest is due on this Global Note (other than maturity), the Trustee shall pay
to the Depository such interest in same day funds. On or before _________, New
York City time, or such other time as shall be agreed upon between the Trustee

and premium, if any, by wire transfer into the account specified by the
Depository. As a condition to the payment, on the Maturity Date or upon
redemption or acceleration, of any part of the principal and applicable premium
of this Global Note, the Depository shall surrender, or cause to be surrendered,
this Global Note to the Trustee, whereupon a new Global Note shall be issued to
the Depository.

     This Global Note is a global security in respect of a duly authorized issue
of Medium-Term Notes, Series ____ (the "Notes of this Series," which term
includes any Global Notes representing such Notes) of the Company issued and to
be issued under an Indenture dated as of _____________, 1998 between the Company
and The Bank of New York, as trustee (the "Trustee," which term includes any
successor Trustee under the Indenture) and indentures supplemental thereto
(collectively, the "Indenture").  Under the Indenture, one or more series of
notes may be issued and, as used herein, the term "Notes" refers to the Notes of
this series and any other outstanding series of Notes. Reference is hereby made
to the Indenture for a more complete statement of the respective rights,
limitations of rights, duties and immunities under the Indenture of the Company,
the Trustee and the Noteholders and of the terms upon which the Notes are and
are to be authenticated and delivered.  This Global Note has been issued in
respect of the series designated on the first page hereof limited in aggregate
principal amount to $__________.

     Prior to the Substitution Date (as hereinafter defined), the Notes will be
secured by first mortgage bonds (the "Pledged First Mortgage Bonds") delivered
by the Company to the Trustee for the benefit of the Holders of the Notes,
issued under the Indenture of First Mortgage, dated October 1, 1947, from the
Company to The Bank of New York as successor trustee to Guarantee Bank and Trust
Company (the "Mortgage Trustee"), as supplemented and amended (the "Mortgage").
Reference is made to the Mortgage and the Indenture for a description of the
rights of the Trustee as holder of the Pledged First Mortgage Bonds, the
property mortgaged and pledged under the Mortgage, the rights of the Company and
of the applicable Mortgage Trustee in respect thereof, the duties and immunities

Pledged First Mortgage Bonds are secured and the circumstances under which
additional first mortgage bonds may be issued.

     FROM AND AFTER SUCH TIME AS ALL FIRST MORTGAGE BONDS (OTHER THAN PLEDGED
FIRST MORTGAGE BONDS) ISSUED UNDER THE MORTGAGE HAVE BEEN RETIRED THROUGH
PAYMENT, REDEMPTION OR OTHERWISE (INCLUDING THOSE FIRST MORTGAGE BONDS THE
PAYMENT FOR WHICH HAS BEEN PROVIDED FOR IN ACCORDANCE WITH THE MORTGAGE) AT,
BEFORE OR AFTER THE MATURITY THEREOF (THE "SUBSTITUTION DATE"), THE PLEDGED
FIRST MORTGAGE BONDS SHALL CEASE TO SECURE THE NOTES IN ANY MANNER, AND, AT THE
OPTION OF THE COMPANY, THE NOTES EITHER (A) WILL BECOME UNSECURED GENERAL
OBLIGATIONS OF THE COMPANY OR (B) WILL BE SECURED BY FIRST MORTGAGE BONDS ISSUED
UNDER AN INDENTURE OTHER THAN THE FIRST MORTGAGE. IN CERTAIN CIRCUMSTANCES PRIOR
TO THE SUBSTITUTION DATE AS PROVIDED IN THE INDENTURE, THE COMPANY IS PERMITTED
TO REDUCE THE AGGREGATE PRINCIPAL AMOUNT OF A SERIES OF PLEDGED FIRST MORTGAGE
BONDS HELD BY THE TRUSTEE, BUT IN NO EVENT PRIOR TO THE SUBSTITUTION DATE TO AN
AMOUNT LESS THAN THE AGGREGATE PRINCIPAL AMOUNT OF THE RELATED SERIES OF NOTES
INITIALLY ISSUED CONTEMPORANEOUSLY WITH SUCH PLEDGED FIRST MORTGAGE BONDS.

     Each Note shall be dated and issued as of the date of its authentication by
the Trustee and shall bear an Original Issue Date or Dates.  Each Note or Global
Note issued upon transfer, exchange or substitution of such Note or Global Note
shall bear the Original Issue Date or Dates of such transferred, exchanged or
substituted Note or Global Note, as the case may be.

     [If applicable, one of the following two sentences: This Global Note may
not be redeemed prior to ____________, _____.  This Global Note is not
redeemable prior to the Maturity Date set forth on the first page hereof.]  [If
applicable:  On or after _______________, ____, this Global Note is redeemable
in whole or in part in increments of $1,000 (provided that any remaining
principal amount of this Global Note shall be at least $100,000) at the option
of the Company at the following redemption prices (expressed as a percentage of
the principal amount to be redeemed) plus accrued interest to the redemption
date:

     Redemption Periods Redemption Prices - ____________________________.

     Notice of redemption will be given by mail to Holders of Notes of this
issue not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture.  In the event of redemption of
this Global Note in part only, a new Global Note or Notes of like tenor and
series for the unredeemed portion hereof will be issued in the name of the
Noteholder hereof upon the surrender hereof.]

     Interest payments for this Global Note shall be computed and paid on the
basis of a 360-day year of twelve 30-day months.  If any Interest Payment Date
or the date on which the principal of this Global Note is required to be paid is
not a Business Day, then payment of principal, premium or interest need not be
made on such date but may be made on the next succeeding Business Day with the
same force and effect as if made on such Interest Payment Date or date on which
the principal of this Global Note is required to be paid and, in the case of
timely payment thereof no interest shall accrue for the period from and after
such Interest Payment Date or the date on which the principal of this Global
Note is required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations as specifically set forth
in the Indenture) if the Company deposits with the 

                                      -3-
<PAGE>
 
Trustee money, U.S. Government Obligations which through the payment of interest
thereon and principal thereof in accordance with their terms will provide money,
or a combination of money and U.S. Government Obligations, in any event in an
amount sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.

     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modifications.  Any such consent or waiver by the Holder of this Global Note
shall be conclusive and binding upon such Holder and upon all future Holders of
this Global Note and of any Note issued upon the registration of transfer hereof
or in exchange therefor or in lieu thereof whether or not notation of such
consent or waiver is made upon the Note.

     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal of and any premium or interest on this Note on or after the
respective due dates expressed herein.

     No reference herein to the Indenture and to provisions of this Global Note
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Global Note at the times, places and rates and the coin or
currency prescribed in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, this Global Note may be transferred only as permitted by the legend
hereto.

     If at any time the Depository for this Global Note notifies the Company
that it is unwilling or unable to continue as Depository for this Global Note or
if at any time the Depository for this Global Note shall no longer be eligible
or in good standing under the Securities Exchange Act of 1934, as amended, or
other applicable statute or regulation, the Company shall appoint a successor
Depository with respect to this Global Note.  If a successor Depository for this
Global Note is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company's
election to issue this Note in global form shall no longer be effective with
respect to this Global Note and the Company will execute, and the Trustee, upon
receipt of a Company Order for the authentication and delivery of individual
Notes in exchange for this Global Note, will authenticate and deliver individual
Notes of like tenor and 

                                      -4-
<PAGE>
 
terms in definitive form in an aggregate principal amount equal to the principal
amount of this Global Note.
 
     The Company may at any time and in its sole discretion determine that all
Notes of this series (but not less than all) issued or issuable in the form of
one or more Global Notes shall no longer be represented by such Global Note or
Notes. In such event, the Company shall execute, and the Trustee, upon receipt
of a Company Order for the authentication and delivery of individual Notes in
exchange for such Global Note, shall authenticate and deliver, individual Notes
of like tenor and terms in definitive form in an aggregate principal amount
equal to the principal amount of such Global Note or Notes in exchange for such
Global Note or Notes. Under certain circumstances specified in the Indenture,
the Depository may be required to surrender any two or more Global Notes which
have identical terms (but which may have differing Original Issue Dates) to the
Trustee, and the Company shall execute and the Trustee shall authenticate and
deliver to, or at the direction of, the Depository a Global Note in principal or
amount equal to the aggregate principal amount of, and with all terms identical
to, the Global Notes surrendered thereto and that shall indicate all Original
Issue Dates and the principal amount applicable to each such Original Issue
Date.

     The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the state of New York.
 
     Unless the certificate of authentication hereon has been executed by the
Trustee, directly or through an Authenticating Agent by manual signature of an
authorized officer, this Global Note shall not be entitled to any benefit under
the Indenture or be valid or obligatory for any purpose.  All capitalized terms
used but not otherwise defined in this Global Note shall have the respective
meanings assigned to them in the Indenture unless otherwise indicated herein.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

                            MEDIUM-TERM NOTE, SERIES

     This Note is one of a duly authorized issue of Medium-Term Notes, Series
___ (the "Notes of this Series") of the Company issued and to be issued under an
Indenture dated as of ________, 1998, between the Company and The Bank of New
York, as trustee (herein called the "Trustee"), which term includes any
successor Trustee under the Indenture) and indentures supplemental thereto
(collectively, the "Indenture").  Under the Indenture, one or more series of
notes may be issued and, as used herein, the term "Notes" refers to the Notes of
this series and any other outstanding series of Notes. Reference is hereby made
for a more complete statement of the respective rights, limitations of rights,
duties and immunities under the Indenture of the Company, the Trustee and the
Noteholders and of the terms upon which the Notes are and are to be
authenticated and delivered.  This Note is one of the series designated on the
face hereof limited in aggregate principal amount to $__________.

[Include the following paragraph if the Company elects to issue Pledged
Substituted Mortgage Bonds (as defined in the Indenture):  The Notes will be
secured by first mortgage bonds (the "Pledged First Mortgage Bonds") delivered
by the Company to the Trustee for the benefit of the Holders of the Notes,
issued under [the Substituted Mortgage (as defined in the Indenture)] from the
Company to ________________, as trustee (the "Mortgage Trustee"), as
supplemented and amended (the "First Mortgage").  Reference is made to the First
Mortgage and the Indenture for a description of the rights of the Trustee as
holder of the Pledged First Mortgage Bonds, the property mortgaged and pledged
under the First Mortgage, the rights of the Company and of the Mortgage Trustee
in respect thereof, the duties and immunities of the Mortgage Trustee, the terms
and conditions upon which the Pledged First Mortgage Bonds are secured and the
circumstances under which additional first mortgage bonds may be issued.]

     [If applicable, one of the following two sentences:  This Note may not be
redeemed prior to __________, ____.  This Note is not redeemable prior to the
Maturity Date set forth on the face hereof.]  [If applicable: On or after
________, ____, this Note is redeemable in whole or in part in increments of
$1,000 (provided that any remaining principal amount of this Note shall be at
least $1,000) at the option of the Company at the following redemption prices
(expressed as a percentage of the principal amount to be redeemed) plus accrued
interest to the redemption date:

Redemption Periods Redemption Prices - ___________________________.

     Notice of redemption will be given by mail to Holders of Notes of this
issue not less than 30 or more than 60 days prior to the date fixed for
redemption, all as provided in the Indenture.  In the event of redemption of
this Note in part only, a new Note or Notes of like tenor for the unredeemed
portion hereof will be issued in the name of the Noteholder hereof upon the
surrender hereof.]
 
     Interest payments for this Note shall be computed and paid on the basis of
a 360-day year of twelve 30-day months.  If any Interest Payment Date or the
date on which the principal of this Note is required to paid is not a Business
Day, then payment of principal, premium or interest need not be made on such
date but may be made on the next succeeding Business Day with the same force and
effect as if made on such Interest Payment Date or the date on which the
principal of this Note is required to be paid, and, in the case of timely
payment thereof, no interest shall accrue for the period from and after such
Interest Payment Date or the date on which the principal of this Note is
required to be paid.

     The Company, at its option, and subject to the terms and conditions
provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations as specifically set forth
in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, as certified by an independent public
accounting firm of national reputation in a written certification delivered to
the Trustee, to pay at maturity or the applicable redemption date (provided that
notice of redemption shall have been duly given or irrevocable provision
satisfactory to the Trustee shall have been duly made for the giving of any
notice of redemption) all outstanding Notes, including principal and any premium
and interest due or to become due to such date of maturity, as the case may be.
 
     If an Event of Default shall occur and be continuing, the principal of the
Notes may be declared due and payable in the manner and with the effect provided
in the Indenture.
 
     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the
Company and the rights of the Noteholders under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of not less than a
majority in principal amount of the outstanding Notes affected by such amendment
or modification.  Any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and of any Note issued upon the registration of transfer hereof or in exchange
therefor in lieu thereof whether or not notation of such consent or waiver is
made upon the Note.
 
     As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal of and any premium or interest on this Note on or after the
respective due dates expressed herein.
 
     No reference herein to the Indenture and to provisions of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the times, places and rates and the coin or currency prescribed
in the Indenture.
 
     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Note register.  Upon
surrender of this Note for registration or transfer at the corporate trust
office of the Trustee or such other office or agency as may be designated by the
Company in the Borough of Manhattan, the City and State of New York, endorsed by
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Note registrar, duly executed by the Holder hereof or the
attorney in fact of such Holder duly authorized in writing, one or more new
Notes of like tenor and of authorized denominations and for the same aggregate
principal amount will be issued to the designated transferee or transferees.
 
                                     -29-
<PAGE>
 
     The Notes of this series are issuable only in registered form, without
coupons, in denominations of $1,000 and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Notes are exchangeable for a like aggregate principal amount of Notes of like
tenor and of a different authorized denomination, as requested by the Holder
surrendering the same.
 
     No service charge shall be made for any such registration of transfer or
exchange but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.
 
     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner thereof for all
purposes, whether or not this Note is overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary. The
Indenture and the Notes shall be governed by, and construed in accordance with,
the laws of the state of New York.

          All capitalized terms used but not otherwise defined in this Note
shall have the respective meanings assigned to them in the Indenture.
