     SECTION 2.13. Securities Issuable in the Form of Global Securities. 01 If
the Company shall establish pursuant to Section 2.02 that the Securities of a
particular series are to be issued in whole or in part as one or more Global
Securities, then the Company shall execute, and the Trustee shall, in accordance
with Section 2.08 and the Company Order delivered to the Trustee thereunder,
authenticate and make available for delivery, one or more Global Securities
which (i) shall represent an aggregate principal amount equal to the aggregate
principal amount of the Outstanding Securities of such series to be represented
by one or more Global Securities, (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: "Except as otherwise provided in
Section 2.13 of the Indenture, this Security may be transferred, in whole but
not in part, only to another nominee of the Depository or to a successor
Depository or to a nominee of such successor Depository."

     02 Notwithstanding any provision of Section 2.10, any Global Security of a
series may be transferred, in whole but not in part, and in the manner provided
in Section 2.10, only to another nominee of the Depository for such series, or
to a successor Depository for such series selected or approved by the Company or
to a nominee of such successor Depository.

     03 If at any time the Depository for Securities of a series notifies the
Company that it is unwilling or unable to continue as Depository for Securities
of such series or if at any time the Depository shall no longer be registered or
in good standing under the Securities Exchange Act of 1934, or other applicable
statute or regulation, and a successor Depository is not appointed by the
Company within 90 days after the Company receives such notice or becomes aware
of such condition, as the case may be, this Section 2.13 shall no longer be
applicable to the Securities of such series and the Company will execute, and
the Trustee, upon receipt of an Company Order for the

                                      -12-


 
  

authentication and delivery of individual Securities of such series, will
authenticate and make available for delivery, Securities of such series, in
authorized denominations, and in an aggregate principal amount equal to the
aggregate principal amount of the Global Security or Global Securities of such
series in exchange for such Global Security or Global Securities.

     The Company may at any time determine that Securities of any series shall
no longer be represented by one or more Global Securities and that the
provisions of this Section 2.13 shall no longer apply to the Securities of such
series. In such event the Company will execute and the Trustee, upon receipt of
an Company Order for the authentication and delivery of individual Securities of
such series, will authenticate and make available for delivery Securities of
such series, in authorized denominations, and in an aggregate principal amount
equal to the aggregate principal amount of the Global Security or Global
Securities of such series in exchange for such Global Security.

     If specified by the Company pursuant to Section 2.02 with respect to a
series of Securities, the Depository for such series of Securities may surrender
a Global Security for such series of Securities in exchange in whole or in part
for individual Securities of such series on such terms as are acceptable to the
Company and such Depository. Thereupon, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, without service
charge,

          (a) to each person specified by such Depository a new individual
     Security or Securities of the same series, of any authorized denomination
     as requested by such person in aggregate principal amount equal to and in
     exchange for such persons' beneficial interest in the Global Security; and

          (b) to such Depository a new Global Security in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     Global Security and the aggregate principal amount of individual Securities
     delivered to Holders thereof.

     In any exchange provided for in any of the preceding paragraphs of this
Section 2.13, the Company will execute and the Trustee will authenticate and
make available for delivery individual Securities in registered form in
authorized denominations.

     Upon the exchange of a Global Security for individual Securities, such
Global Security shall be cancelled by the Trustee. Individual Securities issued
in exchange for a Global Security pursuant to this Section shall be registered
in such names and in such authorized denominations as the Depository for such
Global Security, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.

                                      -13-


 
  

The Trustee shall make such Securities available for delivery to the persons in
whose names such Securities are so registered.


                                  ARTICLE II.

                              2004 SERIES Z BONDS

     s.2.1. There shall be a twenty-fourth series of Bonds, known as and
entitled "First Mortgage Bonds, 8.25% Series Z due 2004" or "First Mortgage
Bonds, 8.25% Series Z" (herein and in the Indenture referred to as the "2004
Series Z Bonds"), and the form thereof shall contain suitable provisions with
respect to the matters hereinafter in this Section specified and shall in other
respects be substantially as set forth in the preambles to the Original
Indenture.

     The aggregate principal amount of 2004 Series Z Bonds which may be
authenticated and delivered and outstanding under the Indenture is Twenty-Five
Million Dollars ($25,000,000).

     The 2004 Series Z Bonds shall bear interest at the rate of 8.25% per annum,
computed on the basis of a 360-day year consisting of twelve 30-day months, and
shall mature on October 1, 2004, subject to prior redemption as described
herein.

     The 2004 Series Z Bonds shall be in the form of registered Bonds without
coupons of denominations of Five Thousand Dollars ($5,000) and any integral
multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
evidence of such authorization. The 2004 Series Z Bonds shall be dated as
provided in s.2.05 of the Indenture. All 2004 Series Z Bonds shall bear interest
from their respective dates, such interest to be payable, upon the terms of and
otherwise in accordance with the 2004 Series Z Bonds, semiannually on the first
day of April and October in each year, the first interest payment date being
April 1, 1995. The principal of and the premium, if any, and interest on the
2004 Series Z Bonds shall be payable at the principal office of the Trustee, in
the City of Chicago, Illinois, in any coin or currency of the United States of
America which at the time of payment shall be legal tender for the payment of
public and private debts.

     Notwithstanding any other provision of the Indenture or of the 2004 Series
Z Bonds, payments of the principal of and the premium, if any, and interest on
any 2004 Series Z Bond may be made directly to the registered holder thereof
without presentation or surrender thereof or the making of any notation thereon
if there shall be filed with the Trustee a Certificate of the Company to the
effect that such registered holder (or the person for whom such registered
holder is a nominee) and the Company have entered into a written agreement that
payment shall

                                      -14-


 
  

be so made; provided, however, that before such registered holder transfers or
otherwise disposes of any 2004 Series Z Bond, such registered holder will, at
its election, either endorse thereon (or on a paper annexed thereto) the
principal amount thereof redeemed and the last date to which interest has been
paid thereon or make such Bond available to the Company at the principal office
of the Trustee for the purpose of making such endorsement thereon.

     The 2004 Series Z Bonds shall not be subject to redemption at the option of
the Company, but shall be subject to mandatory redemption pursuant to s.8.08 of
the Indenture in the manner provided in the applicable provisions of Article Ten
of the Indenture, as amended by Article III of this Supplemental Indenture.

     The 2004 Series Z Bonds shall be excluded from the benefits of, and shall
not be subject to redemption through the operation of, a Mandatory Sinking Fund
pursuant to s.11.02 of the Indenture and shall also be excluded from the
benefits of the covenants of s.9.08 and s.11.01 of the Indenture. Each holder of
a 2004 Series Z Bond consents and shall be deemed to have consented to the
substance of the amendment to s.9.08 of the Indenture as set forth in Article IV
of this Supplemental Indenture. Such consent shall constitute a fundamental term
of the 2004 Series Z Bonds and this Supplemental Indenture.

     Notwithstanding the provisions of s.10.04 or any other provision of the
Indenture, the selection of 2004 Series Z Bonds to be redeemed shall, in case
fewer than all of the outstanding 2004 Series Z Bonds are to be redeemed, be
made by the Trustee pro rata (to the nearest multiple of Five Thousand Dollars
($5,000)) among the registered holders of the 2004 Series Z Bonds in proportion,
as nearly as practicable, to the respective unpaid principal amounts of 2004
Series Z Bonds registered in the names of such holders, with adjustments, to the
extent practicable, to compensate for any prior redemption not made exactly in
such proportion (or otherwise as may be specified by a written order signed by
the registered holders of all outstanding 2004 Series Z Bonds).

     The definitive 2004 Series Z Bonds may be issued in the form of engraved
Bonds or Bonds printed or lithographed on steel engraved borders or Bonds in
typed form on normal bond paper. Subject to the foregoing provisions of this
Section and the provisions of s.2.11 of the Indenture, all definitive 2004
Series Z Bonds shall be fully exchangeable for other Bonds of the same series,
of like aggregate principal amounts, and, upon surrender to the Trustee at its
principal office, shall be exchangeable for other Bonds of the same series of a
different authorized denomination or denominations, as requested by the holder
surrendering the same. The Company will execute, and the Trustee

                                      -15-


 
  

shall authenticate and deliver, registered Bonds without coupons, whenever the
same shall be required for any such exchange.

     s.2.2. 2004 Series Z Bonds in the aggregate principal amount of Twenty-Five
Million Dollars ($25,000,000) may forthwith upon the execution and delivery of
this Supplemental Indenture, or from time to time thereafter, be executed by the
Company and delivered to the Trustee, and shall thereupon be authenticated and
delivered by the Trustee upon compliance by the Company with the provisions of
Articles Four, Five or Six of the Indenture, without awaiting the filing or
recording of this Supplemental Indenture. No additional 2004 Series Z Bonds
shall be issued under Article Four, Five or Six without the consent in writing
of the holders of all the outstanding 2004 Series Z Bonds.


                                  ARTICLE III.

                     REDEMPTION OF THE 2004 SERIES Z BONDS

     s.3.1. The following s.10.65 be and it hereby is added to Article Ten of
the Indenture:

     "s.10.65. In the case of the redemption of 2004 Series Z Bonds out of
moneys deposited with the Trustee pursuant to s.8.08, such 2004 Series Z Bonds
shall, upon compliance with provisions of s.10.04, and subject to the provisions
of s.2.1 of the Twenty-Fourth Supplemental Indenture, be redeemable at the
principal amounts thereof, together with interest accrued thereon to the date
fixed for redemption, without premium."


                                  ARTICLE IV.

                              CONSENT TO AMENDMENT

     s.4.1. Each holder of a 2004 Series Z Bond, by holding such 2004 Series Z
Bond, and as a fundamental term of the 2004 Series Z Bonds and this Supplemental
Indenture, consents and shall be deemed to have consented to the substance of
the following amendment to s.9.08 of the Indenture (the 2004 Series Z Bonds
being excluded from the benefit of the covenants in said s.9.08 by operation of
s.2.1 of this Supplemental Indenture):

     "Section 9.08 of the Indenture including all indentures supplemental
     thereto (in particular, but without limitation, the Thirteenth, Fourteenth,
     Fifteenth and Eighteenth Supplemental Indentures) is hereby amended by
     deleting subparagraph (1) thereof and inserting in its stead the following:


                                      -16-


 
  

     (1) The Company may make Stock Payments if and to the extent that, after
     giving effect thereto, the aggregate amount of all Stock Payments for the
     period from October 1, 1993 to and including the date of the Stock Payment
     in question will not exceed the sum of (or difference between, in the event
     of a loss) $50,000,000 and the Net Earnings (or loss) of the Company for
     such period, taken as one accounting period."

     The foregoing consent shall be irrevocable, shall be continuing and in
effect at all times and shall be deemed to be "concurrent" (within the meaning
of s.13.01 of the Indenture) with the writings relating to the foregoing
amendment by or on behalf of all other Bondholders. Further, the foregoing
consent shall survive any transfer, exchange or substitution of any 2004 Series
Z Bond and shall bind all holders thereof and such holders' transferees,
successors, assigns, heirs and legatees. Each holder of a 2004 Series Z Bond
(and such holder's transferees, successors, assigns, heirs and legatees), by
holding such 2004 Series Z Bond, authorizes and shall be deemed to have
authorized the Trustee to sign, in the name of all holders of the 2004 Series Z
Bonds, any consent or authorization deemed necessary or desirable in the
discretion of the Trustee to evidence the foregoing consent (it being understood
and agreed, however, that this s.4.1 shall constitute, for all purposes of the
Indenture, the written consent by the holders of the 2004 Series Z Bonds to the
foregoing amendment without further act or instrument).


                                   ARTICLE V.

     s.5.1. The Company is lawfully seized and possessed of all the real estate,
franchises and other property described or referred to in the Indenture (except
properties released from the lien of the Indenture pursuant to the provisions
thereof) as presently mortgaged, subject to the exceptions stated therein, such
real estate, franchises and other property are free and clear of any lien prior
to the lien of the Indenture except as set forth in the Granting Clauses of the
Indenture and the Company has good right and lawful authority to mortgage the
same as provided in and by the Indenture.

     s.5.2. The Trustee assumes no duties, responsibilities or liabilities by
reason of this Supplemental Indenture other than as set forth in the Indenture,
and this Supplemental Indenture is executed and accepted by the Trustee subject
to all the terms and conditions of its acceptance of the trust under the
Indenture, as fully as if said terms and conditions were herein set forth at
length.

     s.5.3. The terms used in this Supplemental Indenture shall have the

Indenture is in all respects ratified and confirmed and the Indenture and this

     s.5.5. Neither the approval by the Board of Public Utilities of the State
of New Jersey of the execution and delivery of this Supplemental Indenture nor

Indenture bind said Board or any other public body or authority of the State of
