                                   ARTICLE II
 
               CREATION, PROVISIONS, REDEMPTION, PRINCIPAL AMOUNT
                        AND FORM OF BONDS OF THIS SERIES
 
     SECTION 1. The Company hereby creates a new series of Bonds to be issued
under and secured by the Indenture and to be designated as "First Mortgage
Bonds, 7 3/4% Series due 2025-A" of the Company. The Bonds of this Series shall
be executed, authenticated and delivered in accordance with the provisions of,
and shall in all respects be subject to, all of the terms, conditions and
covenants of the Indenture.
 
     SECTION 2. The Bonds of this Series shall be dated the date of their
authentication, shall mature July 15, 2025, and shall bear interest from the
time hereinafter provided at the rate of 7 3/4% per annum payable semiannually
on the same dates as interest is payable on the Authority Bonds (each such date
herein called an "interest payment date") until the maturity of the Bonds of
this Series, or, in the case of any Bonds of this Series duly called for
redemption, until the redemption date, or, in the case of any default by the
Company in the payment of the principal due on any Bonds of this Series, until
the Company's obligation with respect to the payment of the principal shall be
discharged as provided in the Indenture.
 
     Except as hereinafter provided, each Bond of this Series shall bear
interest (a) from the interest payment date next preceding the date of such Bond
to which interest has been paid, or (b) if the date of such Bond is an interest
payment date to which interest has been paid, then from such date, or (c) if no
interest has been paid thereon, then from July 15, 1995. Notwithstanding the
foregoing, if the date of such Bond is after a Record Date (as hereinafter
defined) and before the next following interest payment date, then it shall bear
interest from such interest payment date; provided, however, that (i) if the
Company shall default in the payment of the interest due on such interest
payment date, then such Bond shall bear interest from the interest payment date
next preceding the date of such Bond to which interest
<PAGE>   9
 
                                        5
 
has been paid, or (ii) if no interest has been paid thereon, then it shall bear
interest from July 15, 1995.
 
     The interest payable on any interest payment date shall be paid to the
respective persons in whose names the Bonds of this Series shall be registered
at the close of business on the Record Date next preceding such interest payment
date, notwithstanding the cancellation of any such Bond upon any transfer or
exchange thereof subsequent to such Record Date and prior to such interest
payment date; provided, however, that, if and to the extent the Company shall
default in the payment of the interest due on such interest payment date, such
defaulted interest shall be paid to the respective persons in whose names such
outstanding Bonds of this Series are registered at the close of business on a
date (the "Subsequent Record Date") not less than 10 days nor more than 15 days
next preceding the date of payment of such defaulted interest, such Subsequent
Record Date to be established by the Company by notice given by mail by or on
behalf of the Company to the registered owners of Bonds of this Series not less
than 10 days next preceding such Subsequent Record Date.
 
     The term "Record Date" shall mean, with respect to any regular interest
payment date of any Bond of this Series, the date which would be the "Regular
Record Date", as defined in the Authority Trust Indenture, applicable to such
regular interest payment date, if it were an "Interest Payment Date", as defined
in the Authority Trust Indenture.
 
     The Bonds of this Series shall be payable as to principal (and premium, if
any) and interest in any coin or currency of the United States of America which
at the time of payment is legal tender for the payment of public and private
debts and shall be payable (as well the interest and the principal thereof and
the premium thereon, if any) at the agency of the Company in the City of
Cleveland, State of Ohio, or, at the option of the Company, at the agency of the
Company in The City of New York. Unless the context indicates a different
meaning, any reference in this Article II to "agency of the Company" means
either the agency of the Company in the City of Cleveland, State of Ohio or the
agency of the Company in The City of New York.
 
     SECTION 3. The principal amount of Bonds of this Series which may be
authenticated and delivered hereunder shall not exceed $45,150,000, except as
otherwise provided in the Indenture.
 
     SECTION 4. The Bonds of this Series shall be issued as fully registered
Bonds only, without coupons, in the denominations of $100,000 and any integral
multiple thereof, provided that one such Bond may be in the denomination equal
to $150,000 and combined with any other
<PAGE>   10
 
                                        6
 
authorized denomination, to the extent necessary to equal the outstanding
principal amount of the Bonds of this Series.
 
     SECTION 5. In the manner and subject to the limitations provided in the
Indenture, Bonds of this Series may be transferred or may be exchanged for a
like aggregate principal amount of Bonds of this Series of other authorized
denominations, in either case without charge, except for any tax or taxes or
other governmental charges incident to such transfer or exchange, at the agency
of the Company in The City of New York.
 
     In the event less than all of the Bonds of this Series at the time
outstanding are called for redemption, the Company shall not be required (a) to
register any transfer or make any exchange of any such Bond for a period of 15
days before the mailing of the notice of redemption of any such Bond, (b) to
register any transfer or make any exchange of any such Bond so called for
redemption in its entirety, or (c) to register any transfer or make any exchange
of any portion of any such Bond so called for redemption.
 
     Except as otherwise provided in Section 2 of this Article II with respect
to the payment of interest, the Company, the agencies of the Company and the
Trustee may deem and treat the person in whose name a Bond of this Series is
registered as the absolute owner thereof for the purpose of receiving any
payment and for all other purposes.
 
     SECTION 6. The Bonds of this Series shall be redeemable only to the extent
provided in this Article II, subject to the provisions contained in Article V of
the Indenture and the form of Bond of this Series.
 
     SECTION 7. The Bonds of this Series shall be subject to redemption by the
Company prior to maturity in whole at any time or in part from time to time at a
redemption price of 100% of the principal amount to be redeemed, but in each
instance only upon receipt by the Trustee of an officers' certificate to the
effect (a) that the Authority, at the direction of the Company, or the Company,
on behalf of the Authority, has given notice to the Authority Trustee that the
Company is exercising its option to direct the redemption of all or a part
(specifying the principal amount) of the Authority Bonds as provided in Section
4.01(a) of the Authority Trust Indenture and (b) that an equivalent principal
amount of Bonds of this Series shall be concurrently called for redemption. Such

amount of the Authority Bonds issued (and all related premium and interest, if

cause the amount of interest payable on such interest payment date on the Bonds
of this Series (hereinafter defined) to equal the amount of interest payable on

maturity of this Bond, or, if this Bond shall be duly called for redemption,
until the redemption date, or, if the Company shall default in the payment of
the principal amount of this Bond, until the Company's obligation with respect

from the interest payment date next preceding the date of this Bond to which
interest has been paid, or (b) if the date of this Bond is an interest payment

interest from July 15, 1995. Subject to certain exceptions provided in said
Indenture, the interest payable on any interest payment date shall be paid to
the person in whose name this Bond shall be registered at the close of business
on the Record Date or, in the case of defaulted interest, on a day preceding the
date of payment thereof established by notice to the registered owner of this
Bond in the manner provided in said Supplemental Indenture. Principal of (and
premium, if any) and interest on this Bond are payable at the agency of the

     This Bond is one of the duly authorized First Mortgage Bonds of the Company
(herein called the "Bonds"), all issued and to be issued under and equally
secured by a Mortgage and Deed of Trust dated July 1, 1940, executed by the
Company to Guaranty Trust Company of New York as Trustee, under which The Chase
Manhattan Bank (National Association) is successor trustee (herein called the
"Trustee"), and all indentures supplemental thereto (said Mortgage as so
supplemented herein called the "Indenture") to which reference is hereby made
for a description of the properties mortgaged and pledged, the nature and extent
of the security, the rights of the registered owner or owners of the Bonds and
of the Trustee in respect thereof and the terms and conditions upon which the
Bonds are, and are to be, secured. The Bonds may be issued in series, for
various principal sums, may mature at different times, may bear interest at
different rates and may otherwise vary as in the Indenture provided. This Bond
is one of a series designated as the First Mortgage Bonds, 7 3/4% Series due
2025-A (herein called the "Bonds of this Series") limited, except as otherwise
provided in the Indenture, in aggregate principal amount to $45,150,000, issued
under and secured by the Indenture and described in the Supplemental Indenture
dated July 15, 1995, between the Company and the Trustee (herein called the
"Supplemental Indenture").
 
     The Bonds of this Series have been issued by the Company and delivered to
the Authority Trustee (hereinafter defined) to evidence and secure its
obligation to pay to the Beaver County Industrial Development Authority
(hereinafter called the "Authority") a portion of the Company's share of the
purchase price for certain air and water pollution control facilities and sewage
and solid waste disposal facilities used in connection with the operation of
Beaver Valley Power Station Unit 2, a nuclear powered generating unit located in
Shippingport, Pennsylvania (hereinafter called the "Project Facilities"), such
portion being in an amount equal to the principal of the Authority Bonds
(hereinafter defined) issued pursuant to the Beaver Valley Pollution Control
Facilities Agreement dated as of April 1, 1974, among the Authority, the
Company, The Toledo Edison Company, Duquesne Light Company, Ohio Edison Company
and Pennsylvania Power Company. That portion of the Company's share of the cost
of the Project Facilities was originally financed with proceeds from the sale by
the Authority of certain bonds, which were refunded from the proceeds of one
series of Collateralized Pollution Control Revenue Refunding Bonds, Series
1995-A (The Cleveland Electric Illuminating Company Beaver Valley Project)
(hereinafter called the "Authority Bonds") issued pursuant to a Trust Indenture,
dated as of July 15, 1995 (hereinafter called the "Authority Trust Indenture"),
between the Authority and Society National Bank, as trustee, (hereinafter
<PAGE>   17
 
                                       13
 
called the "Authority Trustee"). The Bonds of this Series have been assigned by
the Authority to the Authority Trustee as security for the payment of the
principal of and premium, if any, and interest on the Authority Bonds and have
been delivered by the Company on behalf of the Authority directly to, and
registered in the name of, the Authority Trustee.
 
     In the event any Authority Bonds shall be surrendered to the Authority
Trustee or other person for cancellation pursuant to the Authority Trust
Indenture (except upon exchange for other Authority Bonds), Bonds of this Series
equal in principal amount to such Authority Bonds shall be deemed to have been
paid, but only when and to the extent (a) so noted on the Schedule of Payments
hereon by one of the agencies of the Company hereinabove specified and (if such
agency is not the Trustee) written notice by such agency of such notation has
been received by the Trustee or (b) such Bond is surrendered to and cancelled by
the Trustee as provided in the next paragraph; and in the event and to the
extent the principal of (or premium, if any) or interest on any Authority Bonds
shall be paid or deemed to be paid, an equal amount of principal (or premium, if
any) or interest, as the case may be, payable with respect to an aggregate
principal amount of Bonds of this Series equal to the aggregate principal amount
of such Authority Bonds shall be deemed to have been paid, but, in the case of
such payment of principal, only when and to the extent (i) so noted on the
Schedule of Payments hereon by one of the agencies of the Company hereinabove
specified and (if such agency is not the Trustee) written notice by such agency
of such notation has been received by the Trustee or (ii) such Bond is
surrendered to and cancelled by the Trustee as provided in the next paragraph.
When any such payment of principal of this Bond is made, such Bond shall be
surrendered by the registered owner hereof to an agency of the Company for such
notation or to the Trustee for cancellation. If the Authority Bonds are issued
in an aggregate principal amount of less than $45,150,000, an aggregate
principal amount of the Bonds of this Series equal to the difference between
$45,150,000 and the aggregate principal amount of the Authority Bonds issued
(and all related premium and interest, if any) shall be deemed to have been
paid.
 
     In the event that this Bond shall be deemed to have been paid in full, this
Bond shall be surrendered to the Trustee for cancellation. In the event that
this Bond shall be deemed to have been paid in part, this Bond may, at the
option of the registered holder, be surrendered to the Trustee for cancellation,
in which event the Trustee shall cancel this Bond and the Company shall execute
and the Trustee shall authenticate and deliver Bonds of this Series in
authorized denominations in aggregate principal amount equal to the unpaid
balance of the principal amount of this Bond.

     The Bonds of this Series shall be redeemed by the Company prior to maturity
in whole at any time as provided in Section 10 of Article II of the Supplemental
Indenture at a redemption price of 100% of the principal amount to be redeemed,
plus accrued and unpaid interest to the redemption date.
 
     Any redemption of the Bonds of this Series shall be made after written
notice to the registered owner or owners of such Bonds, sent by the Trustee by
first class mail, postage prepaid, at least 30 days and not more than 60 days
before the redemption date (except in the event of redemption described in the
next preceding paragraph in which case such notice shall be mailed not more than
45 days before the redemption date), unless a shorter notice period is consented
to in writing by the registered owner or owners of all Bonds of this Series and
such consent is filed with the Trustee, and such redemption and notice shall be
made in the manner provided in Article II of the Supplemental Indenture, subject
to the provisions of the Indenture. In the event of a partial redemption, the
Trustee shall select the Bonds of this Series to
<PAGE>   19
 
                                       15
 
be redeemed in such manner as the Trustee shall deem appropriate and fair.
 
     In the Forty-Third Supplemental Indenture dated April 15, 1985 between the
Company and the Trustee, the Company has modified, in certain respects, the
redemption provisions in the Indenture effective only with respect to the Bonds
of all series established or created in said Forty-Third Supplemental Indenture
and all supplemental indentures dated after May 28, 1985.
 
     To the extent permitted by and as provided in the Indenture, modifications
or alterations of the Indenture, or of any indenture supplemental thereto, and
of the rights and obligations of the Company and of the holders of the Bonds and
coupons may be made with the consent of the Company by an affirmative vote of
not less than 80% in principal amount of the Bonds entitled to vote then
outstanding at a meeting of Bondholders called and held as provided in the
Indenture and, in case one or more but less than all of the series of Bonds then
outstanding under the Indenture are so affected, by an affirmative vote of not
less than 80% in principal amount of the Bonds of any series entitled to vote
then outstanding and affected by such modification or alteration; provided,
however, that no such modification or alteration shall be made which will affect
the terms of payment of the principal of (or premium, if any) or interest on
this Bond. In the Nineteenth Supplemental Indenture dated November 23, 1976
between the Company and the Trustee, the Company has modified the Indenture
effective from and after the time when none of the Bonds of any series
established prior to the execution of the Nineteenth Supplemental Indenture
shall remain outstanding so as to change "80%" in the foregoing sentence to
"60%" and to make certain other modifications of the Indenture and has reserved
the right to make certain other modifications of the Indenture without any vote,
consent or other action by the holders of Bonds of any series established in the
Nineteenth Supplemental Indenture or in any subsequent supplemental indenture.
 
     If an event of default, as defined in the Indenture, shall occur, the
principal of all the Bonds at any such time outstanding under the Indenture may
be declared or may become due and payable upon the conditions and in the manner
and with the effect provided in the Indenture. The Indenture provides that such
declaration may in certain events be waived by the holders of a majority in
principal amount of the Bonds outstanding.
 
     Subject to the limitations provided in the Indenture, this Bond is
transferable by the registered owner hereof, in person or by duly authorized
attorney, on the books of the Company to be kept for that purpose at the agency
of the Company in The City of New York upon

surrender and cancellation of this Bond, and upon presentation of a duly
executed written instrument of transfer, and thereupon a new fully registered
Bond or Bonds of this Series, of the same aggregate principal amount and in
authorized denominations will be issued to the transferee or transferees in
exchange herefor; and this Bond, with or without other Bonds of this Series, may
in like manner be exchanged for one or more new fully registered Bonds of this
Series of other authorized denominations but of the same aggregate principal
amount; all without charge except for any tax or taxes or other governmental
charges incidental to such transfer or exchange and all subject to the terms and
conditions set forth in the Indenture. In the event less than all of the Bonds
of this Series at the time outstanding are called for redemption, the Company
shall not be required (a) to register any transfer or make any exchange of any
such Bond for a period of 15 days before the mailing of the notice of redemption
of any such Bond, (b) to register any transfer or make any exchange of any such
Bond so called for redemption in its entirety, or (c) to register any transfer
or make any exchange of any portion of any such Bond so called for redemption.
Except as otherwise provided herein with respect to the payment of interest, the
Company, the agencies of the Company and the Trustee may deem and treat the
person in whose name this Bond is registered as the absolute owner hereof for
the purpose of receiving any payment and for all other purposes.
 
     No recourse shall be had for the payment of the principal of or the
interest or premium, if any, on this Bond, or for any claim based hereon or on
the Indenture or any indenture supplemental thereto, against any incorporator,

     to time as reasonably requested by the Trustee, appropriate records of all
     transactions carried out by it as such agency and to furnish the Trustee
     such other information and reports as the Trustee may reasonably require;
 
          (b) Certify that it is eligible for appointment as such agency and
     agree to notify the Trustee promptly if it shall cease to be so eligible;
     and
 
          (c) Agree to indemnify the Trustee, in a manner satisfactory to the

of any notification provided for in or any cancellation made pursuant to Section
