known as First and Refunding Mortgage Bonds, 5.90% Series due 2034. This bond
and all other bonds of said issue are issued and to be issued under and

and deed of trust dated May 1, 1923, duly executed and delivered by The
Counties Gas and Electric Company (to which the Company is successor) to

of this series mature on May 1, 2034, and are issuable only in registered form
without coupons in any denomination authorized by the Company. Any bond or bonds of this series may be exchanged for another bond or

Primary Treasury Dealer selected by the Company. Reference Treasury Dealer Quotations means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined

a 360-day year of twelve 30-day months) at the rate provided in the form of
bond hereinbefore recited, payable on May 1 and November 1 in each year

or bonds of the New Series in a like aggregate principal amount. Any such

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 or more bonds 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 of the New Series, with transfers of ownership effected on the
records of the Depository, the participants and the indirect participants

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

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 21

##### 



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. (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. 22

(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

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

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 23

days prior to any interest payment date, as a record date for determining the

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

Adjusted Treasury Rate means, with respect to any redemption date, the
rate per year equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for the redemption date. Business Day means any day that is not a day on which banking
institutions in New York City are authorized or required by law or regulation
to close. Comparable Treasury Issue means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the
remaining term of the bonds of this series that would be used, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
term of the bonds of the New Series. Comparable Treasury Price means, with respect to any redemption date:  
    
    the average of the Reference Treasury Dealer Quotations for
that redemption date, after excluding the highest and lowest of the
Reference Treasury Dealer Quotations; or  
    
    if the Trustee obtains fewer than three Reference Treasury
Dealer Quotations, the average of all Reference Treasury Dealer
Quotations so received. Reference Treasury Dealer means (1) each of BNP Paribas Securities Corp.
and Merrill Lynch, Pierce, Fenner & Smith Incorporated and their respective
successors, unless any of them ceases to be a primary U.S. Government
securities dealer in New York City (a Primary Treasury Dealer), in which case
the Company shall substitute another Primary Treasury Dealer; and (2) any other
Primary Treasury Dealer selected by the Company. Reference Treasury Dealer Quotations means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined
by the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the trustee by that Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third business day preceding that redemption date. Section 2. In case the Company shall desire to exercise such right to
redeem and pay off all or any part of such bonds of the New Series as
hereinbefore provided it shall comply with all the terms and provisions of
Article III of the Mortgage, as amended, applicable thereto, and such
redemption shall be made under and subject to the terms and provisions of
Article III and in the manner and with the effect therein provided, but at the
time or times and upon mailing of notice, all as hereinbefore set forth in
Section 1 of this Article. No publication of notice of any redemption of any
bonds of the New Series shall be required. 25

principal (including the full amount of any applicable optional
redemption price) of any bond or bonds of the New Series whether at the

(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. ARTICLE VI. CONCERNING THE TRUSTEE The Trustee hereby accepts the trust herein declared and provided and
agrees to perform the same upon the terms and conditions set forth in the
Mortgage, as amended and supplemented, and upon the following terms and
