        known as its Mortgage Bonds of the series designated in its title, all issued
        and to be issued under and equally secured (except as to any money, obligations
        or other instruments, or earnings thereon, deposited with the Trustee in
        accordance with the provisions of the Indenture hereinafter mentioned for
        the
        bonds of any particular series) by a General Mortgage Indenture and Deed
        of
        Trust, dated as of January 1, 1998, executed by the Company to The
        Bank of
        New York, as Trustee, as amended and supplemented by indentures supplemental
        thereto, to which Indenture as so amended and supplemented (herein referred
        to
        as the “Indenture”) reference is made for a description of the property
        mortgaged and pledged, the nature and extent of the security, the rights
        of the
        holders of the bonds in respect thereof and the terms and conditions upon
        which
        the bonds are secured.
  Bonds
        of this
        series shall be issuable in denominations of $1.00.
  The
        bonds of this
        series shall be redeemed in whole or in part by payment of the principal
        amount
        to be redeemed, plus accrued interest thereon, if any, to the date fixed
        for
        redemption, upon receipt by the Trustee of a written advice from the holder
        hereof (i) stating that the Company, after demand therefor, has failed
        to
        pay amounts it is obligated to pay under (A) the Master Agreement dated as
        of
        March 31, 2005 by and among the Company, The Cleveland Electric
        Illuminating Company, the Energy Acquisition Corporation II (“EAC II”), the Ohio

        among
        the Company, The Toledo Edison Company, EAC II, OSC and U.S. Bank, as trustee;
        and (C) the Master Agreement dated as of March 31, 2005 by and among
        the
        Company, EAC II, OSC and U.S. Bank, as trustee, (ii) specifying
        the
        amounts not paid, which amount (rounded up to the nearest $1,000) shall be
        the
        principal amount of the bonds of this series to be redeemed, and (iii)
        establishing a redemption date which shall not be less than 30 nor more than
        60
        days from the date of such written advice. The date of such written advice
        shall
        become the initial interest accrual date (the “Initial Interest Accrual Date”)
        with respect to the principal amount of the bonds of this series to be redeemed
        with respect to such written advice, but shall not constitute the Initial
        Interest Accrual Date for any other bonds of this series.
  Bonds
        of this
        series are not otherwise redeemable prior to their maturity.
  Bonds
        of this
        series shall be deemed to be paid and cancelled and no longer outstanding
        under
        the Indenture to the extent that the aggregate principal amount thereof exceeds
        105% of the aggregate principal amount of Energy Acquisition Corporation
        II
        Electric Energy Acquisition Taxable Revenue Bonds, Series 2005 (Energy for
        Education Program II (the “EAC Bonds”)), issued and outstanding from time to

 “EAC
        Bond Interest
        Rate” shall mean the interest rate borne from time to time on the EAC
        Bonds.
  Unless
        and until
        the Trustee shall have received the aforesaid written advice, the Trustee
        may
        conclusively presume that the obligation of the Company to pay the principal
        of,
        and interest, if any, on the bonds of this series shall not have
        arisen.
  The
        principal
        hereof may be declared or may become due on the conditions, in the manner
        and at
        the time set forth in the Indenture, upon the occurrence of an Event of Default
        (as defined in the Indenture) as in the Indenture provided.
  No
        recourse shall be had for the payment of the principal of or premium, or
        interest if any, on this bond, or any part hereof, or for any claim based
        hereon
        or otherwise in respect hereof, or of the indebtedness represented hereby,
        or
        upon any obligation, covenant or agreement under the Indenture, against any
        incorporator, stockholder, officer or director, as such, past, present or
        future
        of the Company or of any predecessor or successor corporation (either directly
        or through the Company or a predecessor or successor corporation), whether
        by
        virtue of any Constitutional provision, statute or rule of law, or by the
        enforcement of any assessment or penalty or otherwise, all such liability
        of
        incorporators, stockholders, officers and directors being released by the
        registered owner hereof by the acceptance of this bond and being likewise
        waived
        and released by the terms of the Indenture.
  The
        bonds of this
        series are issuable only as a single registered bond without coupons in a
        denomination equal to the aggregate principal amount of bonds of this series
        outstanding. If and to the extent this bond becomes transferable, the registered
        owner hereof, in person or by attorney duly authorized, may effectuate such
        transfer at an office or agency of the Company, in the Borough of Manhattan,
        The
        City of New York, New York or the City of Akron, Ohio, upon surrender
        and
        cancellation of this bond and thereupon a new registered bond or bonds of
        the
        same series for a like principal amount, will be issued to the transferee
        in
        exchange therefor, as provided in the Indenture, and upon payment, if the
        Company shall require it, of the transfer charges therein prescribed. The
        Company and the Trustee may deem and treat the person in whose name this
        bond is
        registered as the absolute owner for the purpose of receiving payment of
        or on
        account of the principal and interest due hereon and for all other
        purposes.

        that all such bonds of Guarantee Series C are to be issued, authenticated

        covenants, conditions, uses and trusts in the Indenture set forth, and the
        parties hereto mutually agree as follows:
  SECTION
        1.   Bonds
        of Guarantee
        Series C shall be designated as the Company’s “Mortgage Bonds, Guarantee
        Series C of 2005 due 2009.” The bonds of Guarantee Series C shall bear
        interest from the Initial Interest Accrual Date as provided in the form of
        the
        bond hereinabove set forth, and such provisions are incorporated at this

        Ohio.
  Definitive
        bonds of
        Guarantee Series C may be issued, originally or otherwise, only as
        registered bonds, substantially in the form of bond hereinabove set forth,
        and
        in a single denomination equal to the aggregate principal amount thereof
        that is
        Outstanding. Delivery of a bond of Guarantee Series C to the Trustee
        for
        authentication shall be conclusive evidence that its serial number has been
        duly
        approved by the Company.

        2.   Bonds

        exceeds 105% of the aggregate principal amount of Energy Acquisition
        Corporation II Electric Energy Acquisition Taxable Revenue Bonds,

        of bond of Guarantee Series C hereinabove set forth). The Trustee may rely
        on an
        Officer’s Certificate to this effect.
  Unless
        and until
        the Trustee shall have received from the holder of the bond of Guarantee
        Series
        C any written advice establishing a redemption date, as provided in the form
        of
        bond of Guarantee Series C hereinabove set forth, the Trustee may
        conclusively presume that the obligation of the Company to pay the principal
        of,
        and interest, if any, on the bonds of Guarantee Series C shall not
        have
        arisen.

        Holders thereof, in person or by attorney duly authorized, at an office or
        agency of the Company in the Borough of Manhattan, The City of New York,
        New York or the City of Akron, Ohio, but only in the manner and upon
        the
