         "__% Series due 20__"

                                   ARTICLE II.

                             BONDS OF THE NEW SERIES

         Section 1. The bonds of the New Series shall be designated as
hereinabove specified for such designation in the recital immediately preceding
the form of bonds of the New Series,

                                       18

<PAGE>

subject however, to the provisions of Section 2 of Article I of the Mortgage, as
amended, and are issuable only as registered bonds without coupons,
substantially in the form hereinbefore recited; and the issue thereof shall be
limited to $            principal amount.

         The bonds of the New Series shall bear interest from the date thereof
and shall be dated as of the interest payment date to which interest was paid
next preceding the date of issue unless (a) such date of issue is an interest
payment date to which interest was paid, in which event such bonds shall be
dated as of such interest payment date, or (b) issued prior to the occurrence of
the first interest payment date on which interest is to be paid, in which event
such bonds shall be dated          . The bonds of the New Series shall mature on
                 .

         The bonds of the New Series shall bear interest (computed on the basis
of a 360-day year of twelve 30-day months) at the rate provided in the form of
bond hereinbefore recited, payable on             and               in each year
commencing on         until the Company's obligation with respect to the payment
of principal thereof shall have been discharged. Both principal and interest on
bonds of the New Series shall be payable at the office or agency of the Company
in the City of Philadelphia, Pennsylvania, or, at the option of the holder, at
the office or agency of the Company in the Borough of Manhattan, The City of New
York, and shall be payable 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.

         The bonds of the New Series shall be in any denomination authorized by
the Company.

         Any bond or bonds of the New Series shall be exchangeable for another
bond or bonds of the New Series in a like aggregate principal amount. Any such
exchange may be made upon presentation at the office of the Trustee in the City
of Philadelphia, Pennsylvania, or, at the option of the holder, at the office or
agency of the Company in the Borough of Manhattan, The City of New York, without
any charge other than a sum sufficient to reimburse the Company for any stamp
tax or other governmental charge incident to the exchange.

         (The following Sections 2 and 3 shall apply if the bonds of the New
Series are to be issued in book-entry only form.)

         Section 2. (a) Initially, the bonds of the New Series shall be issued
pursuant to a book-entry system administered by the Depository Trust Company (or
its successor, referred to herein as the "Depository") as a global security with
no physical distribution of bond certificates to be made except as provided in
this Section 2. Any provisions of the Mortgage or the bonds of the New Series
requiring physical delivery of bonds shall, with respect to any bonds of the New
Series held under the book-entry system, be deemed to be satisfied by a notation
on the bond registration books maintained by the Trustee that such bonds are
subject to the book-entry system.

         (b) So long as the book-entry system is being used, one bond of the New
Series in the aggregate principal amount of the bonds of the New Series and
registered in the name of the Depository's nominee (the "Nominee") will be
issued and required to be deposited with the Depository and held in its custody.
The book-entry system will be maintained by the Depository and its participants
and indirect participants and will evidence beneficial ownership of the bonds

                                       19

<PAGE>

of the New Series, with transfers of ownership effected on the records of the
Depository, the participants and the indirect participants pursuant to rules and
procedures established by the Depository, the participants and the indirect
participants. The principal of and any premium on each bond of the New Series
shall be payable to the Nominee or any other person appearing on the
registration books as the registered holder of such bond or its registered
assigns or legal representative at the office of the office or agency of the
Company in the City of Philadelphia, Pennsylvania or the Borough of Manhattan,
The City of New York. So long as the book-entry system is in effect, the
Depository will be recognized as the holder of the bonds of the New Series for
all purposes. Transfers of principal, interest and any premium payments or
notices to participants and indirect participants will be the responsibility of
the Depository, and transfers of principal, interest and any premium payments or
notices to beneficial owners will be the responsibility of participants and
indirect participants. No other party will be responsible or liable for such
transfers of payments or notices or for maintaining, supervising or reviewing
such records maintained by the Depository, the participants or the indirect
participants. While the Nominee or the Depository, as the case may be, is the
registered owner of the bonds of the New Series, notwithstanding any other
provisions set forth herein, payments of principal of, redemption premium, if
any, and interest on the bonds of the New Series shall be made to the Nominee or
the Depository, as the case may be, by wire transfer in immediately available
funds to the account of such holder. Without notice to or consent of the
beneficial owners, the Trustee with the consent of the Company and the
Depository may agree in writing to make payments of principal, redemption price
and interest in a manner different from that set forth herein. In such event,
the Trustee shall make payment with respect to the bonds of the New Series in
such manner as if set forth herein.

         (c) The Company may at any time elect (i) to provide for the
replacement of any Depository as the depository for the bonds of the New Series
with another qualified depository, or (ii) to discontinue the maintenance of the
bonds of the New Series under book-entry system. In such event, the Trustee
shall give 30 days prior notice of such election to the Depository (or such
fewer number of days acceptable to such Depository).

         (d) Upon the discontinuance of the maintenance of the bonds of the New
Series under a book-entry system, the Company will cause the bonds to be issued
directly to the beneficial owners of the bonds of the New Series, or their
designees, as further described below. In such event, the Trustee shall make
provisions to notify participants and beneficial owners of the bonds of the New
Series, by mailing an appropriate notice to the Depository, that bonds of the
New Series will be directly issued to beneficial owners of the bonds as of a
date set forth in such notice (or such fewer number of days acceptable to such
Depository).

         (e) In the event that bonds of the New Series are to be issued to
beneficial owners of the bonds, or their designees, the Company shall promptly
have bonds of the New Series prepared in certificated form registered in the
names of the beneficial owners of such bonds shown on the records of the
participants provided to the Trustee, as of the date set forth in the notice
above. Bonds issued to beneficial owners, or their designees shall be
substantially in the form set forth in this Supplemental Indenture, but will not
include the provision related to global securities.

                                       20

<PAGE>

          (f)   If the Depository is replaced as the depository for the bonds of
the New Series with another qualified depository, the Company will issue a
replacement global security substantially in the form set forth in this
Supplemental Indenture.

          (g)   The Company and the Trustee shall have no liability for the
failure of any Depository to perform its obligations to any participant, any
indirect participant or any beneficial owner of any bonds of the New Series, and
the Company and the Trustee shall not be liable for the failure of any
participant, indirect participant or other nominee of any beneficial owner or
any bonds of the New Series to perform any obligation that such participant,
indirect participant or other nominee may incur to any beneficial owner of the
bonds of the New Series.

          (h)   Notwithstanding any other provision of the Mortgage, on or prior
to the date of issuance of the bonds of the New Series the Trustee shall have
executed and delivered to the initial Depository a Letter of Representations
governing various matters relating to the Depository and its activities
pertaining to the bonds of the New Series. The terms and provisions of such
Letter of Representations are incorporated herein by reference and, in the event
there shall exist any inconsistency between the substantive provisions of the
said Letter of Representations and any provisions of the Mortgage, then, for as
long as the initial Depository shall serve as depository with respect to the
bonds of the New Series, the terms of the Letter of Representations shall
govern.

          (i)   The Company and the Trustee may rely conclusively upon (i) a
certificate of the Depository as to the identity of a participant in the
book-entry system; (ii) a certificate of any participant as to the identity of
any indirect participant and (iii) a certificate of any participant or any
indirect participant as to the identity of, and the respective principal amount
of bonds of the New Series owned by, beneficial owners.

     Section 3. So long as the bonds of the New Series are held by The
Depository Trust Company, such bonds of the New Series shall bear the following
legend:

     UNLESS THIS BOND IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO THE COMPANY OR ITS
AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY BOND ISSUED IS
REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY A PERSON IS
WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

     Section 4. So long as any of the bonds of the New Series remain
outstanding, the Company shall keep at its office or agency in the Borough of
Manhattan, The City of New York, as well as at the office of the Trustee in the
City of Philadelphia, Pennsylvania, books for the registry and transfer of
outstanding bonds of the New Series, in accordance with the terms and provisions
of the bonds of the New Series and the provisions of Section 8 of Article I of
said Mortgage.

                                       21

<PAGE>

     Section 5. So long as any bonds of the New Series remain outstanding, the
Company shall maintain an office or agency in the City of Philadelphia,
Pennsylvania, and an office or agency in the Borough of Manhattan, The City of
New York, for the payment upon proper demand of the principal of, the interest
on, or the redemption price of the outstanding bonds of the New Series, and will
from time to time give notice to the Trustee of the location of such office or
agency. In case the Company shall fail to maintain for such purpose an office or
agency in the City of Philadelphia or shall fail to give such notice of the
location thereof, then notices, presentations and demands in respect of the
bonds of the New Series may be given or made to or upon the Trustee at its
office in the City of Philadelphia and the principal of, the interest on, and
the redemption price of said bonds in such event be payable at said office of
the Trustee. All bonds of the New Series when paid shall forthwith be cancelled.

     Section 6. The Company may fix a date, not more than fourteen calendar days
prior to any interest payment date, as a record date for determining the
registered holder of each bond of the New Series entitled to such interest
payment, in which case only the registered holder of such bond on such record
date shall be entitled to receive such payment, notwithstanding any transfer of
such bond upon the registration books subsequent to such record date.

     Section 7. The bonds of the New Series shall be issued under and subject to
all of the terms and provisions of the Mortgage, of the indentures supplemental
thereto referred to in the recitals hereof and of this Supplemental Indenture
which may be applicable to such bonds or applicable to all bonds issued under
the Mortgage and indentures supplemental thereto.

                                  ARTICLE III.

                           ISSUE AND AUTHENTICATION OF

     In addition to any bonds of any series which may from time to time be
executed by the Company and authenticated and delivered by the Trustee upon
compliance with the provisions of the Mortgage and/or of any indenture
supplemental thereto, bonds of the New Series of an aggregate principal amount
not exceeding $     shall forthwith be executed by the Company and delivered to

Indenture shall have been recorded, authenticate and deliver said bonds to or

the Company, under the terms and provisions of paragraph    of Section 3 of
Article II of the Mortgage, as amended.

                                   NEW SERIES

     Section 1. The bonds of the New Series shall be redeemable, at the option
of the Company, as a whole or in part, at any time upon notice sent by the
Company through the mail, postage prepaid, at least thirty (30) days and not

Article. No publication of notice of any redemption of any bonds of the New
Series shall be required.

     (In the event that bonds of this series are redeemable both pursuant to
the sinking fund herein provided and also at the option of the Company, the
following Articles IV and V shall be included instead.)

                                  ARTICLE IV.

                        SINKING FUND FOR THE BONDS OF THE
                                   NEW SERIES

     The Company covenants that so long as any of the bonds of the New Series
shall be outstanding it will, on or before        of each of the years 20 to   ,
both inclusive, pay or cause to be paid to the Trustee, as and for a sinking
fund, the sum in cash of $       . The Company also has the non-cumulative
option to increase the amount of such sinking fund payment for any such year
(and the principal amount of such bonds so to be redeemed) by an additional sum
not exceeding $        , in cash. Each such payment is hereinafter called a
"sinking fund payment." On or before        of each of the years 20   to       ,
both inclusive, the Company shall deliver to the Trustee a certificate of its
Treasurer or one of its Vice Presidents (1) setting forth the amount of the
sinking fund payment required to be made on or before the next succeeding      ,
(2) stating the principal amount of the bonds of the New Series due to be called
for redemption on the next succeeding      by application of such sinking fund
payment, and (3) irrevocably directing the Trustee to give notice of redemption
pursuant to the provisions of Article V hereof and to apply such sinking fund
payment to such

                                       23

<PAGE>

redemption. Neither the Company's failure to deliver such certificate nor the
Trustee's failure to give such notice of redemption shall affect the Company's
obligation to make any sinking fund payment, and no such notice of a sinking
fund redemption shall be conditioned upon receipt of the redemption monies by
the Trustee before the date fixed for redemption.

                                   ARTICLE V

                           REDEMPTION OF BONDS OF THE
                                   NEW SERIES

     Section 1. The bonds of the New Series shall not be redeemable in whole or
in part except as set forth in this Article V and in Article IV hereof. The
bonds of the New Series shall be redeemable at the option of the Company, or and
after       , as a whole or in part at any time upon notice sent by the Company
through the mail, postage prepaid, at least thirty (30) days and not more than
forty-five (45) days prior to the date fixed for redemption, to the registered
holder of each bond to be redeemed in whole or in part, addressed to such holder
at his address appearing upon the registration books, at the applicable optional
redemption price (expressed as a percentage of the principal amount of each bond
to be redeemed) specified in the form of bonds of said series set forth in the
recitals of this Supplemental Indenture; and shall also be subject to
redemption, in part, pursuant to the sinking fund provided for in Article IV of
this Supplemental Indenture, on        of each of the years        to          ,
both inclusive, at 100% of the principal amount, together, in each case, with
accrued interest to the date fixed for redemption.

     Section 2. In the case of each partial redemption of the bonds of the New
Series, including any partial redemption provided for in Article IV of this
Supplemental Indenture, the Trustee shall draw by lot, in any manner by it
deemed proper, an amount of bonds of the New Series equal to the aggregate
principal amount to be redeemed; provided, that the principal amount to be
redeemed with respect to bonds of the New Series at the time outstanding held by
each registered holder shall not exceed that proportion of the unpaid principal
amount of such bonds held by such holder as the aggregate principal amount to be
redeemed with respect to all bonds of the New Series bears to the aggregate
unpaid principal amount of all such bonds. No publication of notice of any
redemption of bonds of the New Series shall be required. All redemptions shall
be made under and subject to the terms and provisions of Article III of the
Mortgage, as amended, and in the manner and with the effect therein provided,
but at the time or times and at the respective redemption rates and upon mailing
of notice, all as hereinbefore set forth in Section 1 of this Article and in
Article IV hereof.

     Section 3. In the case of each redemption of bonds of the New Series
pursuant to the provisions of this Article V and Article IV hereof, there shall
become due and payable on the date fixed for redemption the principal amount of
each such bond to be redeemed (including the full amount of any applicable
optional redemption price), together with accrued interest to such date. The
Company covenants that it will deposit or cause to be deposited with the
Trustee, not later than the opening of business on the dates fixed for
redemption, a sum in cash sufficient for the purposes of such redemption
(including the payment of any such optional redemption proceeds and such
interest), and, upon such receipt, the Trustee shall be deemed to have been

                                       24

<PAGE>

irrevocably directed to apply such cash toward the redemption of such bonds. So
long as any bonds of the New Series remain outstanding, no redemption of bonds
of the New Series pursuant to this Article V shall reduce the amount of the
sinking fund payment required to be made by Article IV hereof or the principal
amount of the bonds of the New Series to be redeemed on any sinking fund
redemption date.

     Section 4. The Company will not, and will not permit any affiliate of the
Company to, directly or indirectly purchase or otherwise acquire any outstanding
bond of the New Series or any portion thereof other than by redemption as set
forth in this Article V and Article IV hereof.

addition to the events of default heretofore enumerated in paragraphs (a)

"event of default" under the Mortgage, as fully as if such events were
enumerated therein:

          (e)   default shall be made in the due and punctual payment of the
     principal (including the full amount of any applicable optional redemption
     price) of any bond or bonds of the New Series whether at the maturity of
     said bonds, or at a date fixed for redemption of said bonds, or any of
     them, or by declaration as authorized by the Mortgage;

     sinking fund, the following paragraph (f) shall also be included.)

          (f)   default shall be made by the Company in any sinking fund payment
     under this        Supplemental Indenture in respect to the bonds of the New
     Series, as and when the same become due and payable, and any such default
     shall continue for the period of one (1) day.

     Section 2. So long as any bonds of the New Series remain outstanding,
Section 10 of Article VIII of the Mortgage, as heretofore amended, is hereby
further amended by inserting in the first paragraph of such Section 10,
immediately after the words "as herein provided," at the end of clause (2)
thereof, the following:

     "or (3) in case default shall be made in any payment of any interest on any
bond or bonds secured by this indenture or in the payment of the principal
(including any applicable optional redemption price) of any bond or bonds
secured by this indenture, where such default is not of the character referred
to in clause (1) or (2) of this Section 10 but constitutes an event of default
within the meaning of Section 2 of this Article VIII."
