              So
                long as any of the Notes are outstanding, the Company will not create
                or

                utility properties or tangible assets now owned or hereafter acquired
                to
                secure any indebtedness for borrowed money (“Secured Debt”), without
                providing that such Notes will be similarly secured. This restriction
                does
                not apply to the Company’s subsidiaries, nor will it prevent any of them
                from creating or permitting to exist Liens on their property or assets
                to
                secure any Secured Debt. In addition, this restriction does not prevent
                the creation or existence of:

            
	 	 	 	 
	 	 	
              o

                property (or created within one year after completion of such acquisition
                or construction), whether by purchase, merger, construction or otherwise,
                or to secure the payment of all or any part of the purchase price
                or
                construction cost thereof, including the extension of any Liens to
                repairs, renewals, replacements substitutions, betterments, additions,
                extensions and improvements then or thereafter made on the property
                subject thereto;

            
	 	 	 	 
	 	 	
              o

            	
              Financing
                of the Company’s accounts receivable for electric
                service

            
	 	 	 	 
	 	 	
              o

            	
              Any
                extensions, renewals or replacements (or successive extensions, renewals
                or replacements), in whole or in part, of liens permitted by the
                foregoing
                clauses; and

            
	 	 	 	 
	 	 	
              o

            	
              The
                pledge of any bonds or other securities at any time issued under
                any of
                the Secured Debt permitted by the above clauses.

            
	 	 	 	 
	 	 	
              In
                addition to the permitted issuances above, Secured Debt not otherwise
                so
                permitted may be issued in an amount that does not exceed 15% of
                Net
                Tangible Assets as defined below

            
	 	 	 
	 	 	
              “Net
                Tangible Assets” means the total of all assets (including revaluations
                thereof as a result of commercial appraisals, price level restatement

                reserves and deductions, but excluding goodwill, trade names, trademarks,
                patents, unamortized debt discount and all other like intangible
                assets
                (which term shall not be construed to include such revaluations),

                aggregate of the Company’s current liabilities appearing on such balance
                sheet. For purposes of this definition, the Company's balance sheet
                does
                not include assets and liabilities of its subsidiaries.

            
	 	 	 
	 	 	
              This
                restriction also will not apply to or prevent the creation or existence
                of
                leases made, or existing on property acquired, in the ordinary course
                of
                business.

    COLUMBUS
      SOUTHERN POWER COMPANY, a corporation duly organized and existing under the
      laws
      of the State of Ohio (herein referred to as the "Company", which term includes
      any successor corporation under the Indenture hereinafter referred to), for
      value received, hereby promises to pay to CEDE & CO. or registered assigns,
      the Principal Amount specified above on the Stated Maturity specified above,
      and
      to pay interest on said Principal Amount from the Original Issue Date specified
      above or from the most recent interest payment date (each such date, an
      "Interest Payment Date") to which interest has been paid or duly provided for,
      semi-annually in arrears on April 1 and October 1 in each year, commencing
      on
      April 1, 2006, at the Interest Rate per annum specified above, until the
      Principal Amount shall have been paid or duly provided for. Interest shall
      be
      computed on the basis of a 360-day year of twelve 30-day months.

    


    The
      interest so payable, and punctually paid or duly provided for, on any Interest
      Payment Date, as provided in the Indenture, as hereinafter defined, shall be
      paid to the Person in whose name this Note (or one or more Predecessor
      Securities) shall have been registered at the close of business on the Regular
      Record Date with respect to such Interest Payment Date, which shall be the
      March
      15 or September 15 (whether or not a Business Day), as the case may be,
      immediately preceding such Interest Payment Date, provided that interest payable
      on the Stated Maturity or any redemption date shall be paid to the Person to
      whom principal is paid. Any such interest not so punctually paid or duly
      provided for shall forthwith cease to be payable to the Holder on such Regular
      Record Date and shall be paid as provided in said Indenture.

    


    If
      any
      Interest Payment Date, any redemption date or Stated Maturity is not a Business
      Day, then payment of the amounts due on this Note on such date will be made
      on
      the next succeeding Business Day, and no interest shall accrue on such amounts
      for the period from and after such Interest Payment Date, redemption date or
      Stated Maturity, as the case may be, with the same force and effect as if made
      on such date. The principal of (and premium, if any) and the interest on this
      Note shall be payable at the office or agency of the Company maintained for
      that
      purpose in the Borough of Manhattan, the City of New York, New York, in any
      coin
      or currency of the United States of America which at the time of payment is
      legal tender for payment of public and private debts; provided, however, that
      payment of interest (other than interest payable on the Stated Maturity or
      any
      redemption date) may be made at the option of the Company by check mailed to
      the
      registered holder at such address as shall appear in the Security
      Register.

    


    This
      Note
      is one of a duly authorized series of Notes of the Company (herein sometimes
      referred to as the "Notes"), specified in the Indenture, all issued or to be
      issued in one or more series under and pursuant to an Indenture dated as of
      September 1, 1997 duly executed and delivered between the Company and Deutsche
      Bank Trust Company Americas (formerly Bankers Trust Company), a corporation
      organized and existing under the laws of the State of New York, as Trustee
      (herein referred to as the "Trustee") (such Indenture, as originally executed
      and delivered and as thereafter supplemented and amended being hereinafter
      referred to as the "Indenture"), to which Indenture and all indentures
      supplemental thereto or Company Orders reference is hereby made for a
      description of the rights, limitations of rights, obligations, duties and
      immunities thereunder of the Trustee, the Company and the holders of the Notes.
      By the terms of the Indenture, the Notes are issuable in series which may vary
      as to amount, date of maturity, rate of interest and in other respects as in
      the
      Indenture provided. This Note is one of the series of Notes designated on the
      face hereof.

    


    This
      Note
      may be redeemed by the Company at its option, in whole at any time or in part
      from time to time, upon not less than thirty but not more than sixty days'
      prior
      notice given by mail to the registered owners of the Notes at a redemption
      price
      equal to the greater of (i) 100% of the principal amount of the Notes being
      redeemed and (ii) the sum of the present values of the remaining scheduled
      payments of principal and interest on the Note being redeemed (excluding the
      portion of any such interest accrued to the date of redemption) discounted
      (for
      purposes of determining present value) to the redemption date on a semi-annual
      basis (assuming a 360-day year consisting of twelve 30-day months) at the
      Treasury Rate (as defined below) plus 30 basis points, plus, in each case,
      accrued interest thereon to the date of redemption.

    


    "Treasury
      Rate" means, with respect to any redemption date, the rate per annum 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 such redemption
      date.

    


    "Comparable
      Treasury Issue" means the United States Treasury security selected by an
      Independent Investment Banker as having a maturity comparable to the remaining
      term of the Notes that would be utilized, 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
      Notes.

    


    "Comparable
      Treasury Price" means, with respect to any redemption date, (1) the average
      of
      the Reference Treasury Dealer Quotations for such redemption date, after
      excluding the highest and lowest such Reference Treasury Dealer Quotations,
      or
      (2) if we obtain fewer than four such Reference Treasury Dealer Quotations,
      the
      average of all such quotations.

    


    "Independent
      Investment Banker" means one of the Reference Treasury Dealers appointed by
      the
      Company and reasonably acceptable to the Trustee.

    


    "Reference
      Treasury Dealer" means a primary U. S. government securities dealer in New
      York
      City selected by the Company and reasonably acceptable to the
      Trustee.

    


    "Reference
      Treasury Dealer Quotation" means, with respect to the 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 such
      Reference Treasury Dealer at or before 5:00 p.m., New York City time, on the
      third Business Day preceding such redemption date.

    


    The
      Company shall not be required to (i) issue, exchange or register the transfer
      of
      any Notes during a period beginning at the opening of business 15 days before
      the day of the mailing of a notice of redemption of less than all the
      outstanding Notes of the same series and ending at the close of business on
      the
      day of such mailing, nor (ii) register the transfer of or exchange of any Notes
      of any series or portions thereof called for redemption. This Global Note is
      exchangeable for Notes in definitive registered form only under certain limited
      circumstances set forth in the Indenture.

    


    In
      the
      event of redemption of this Note in part only, a new Note or Notes of this
      series, of like tenor, for the unredeemed portion hereof will be issued in
      the
      name of the Holder hereof upon the surrender of this Note.

    


    In
      case
      an Event of Default, as defined in the Indenture, shall have occurred and be
      continuing, the principal of all of the Notes may be declared, and upon such
      declaration shall become, due and payable, in the manner, with the effect and
      subject to the conditions provided in the Indenture.

    


    The
      Indenture contains provisions for defeasance at any time of the entire
      indebtedness of this Note upon compliance by the Company with certain conditions
      set forth therein.

    


    As
      described in the Company Order and Officers’ Certificate, so long as this Note
      is outstanding, the Company is subject to a limitation on Liens as described
      therein.

    


    The
      Indenture contains provisions permitting the Company and the Trustee, with
      the
      consent of the Holders of not less than a majority in aggregate principal amount
      of the Notes of each series affected at the time outstanding, as defined in
      the
      Indenture, to execute supplemental indentures for the purpose of adding any
      provisions to or changing in any manner or eliminating any of the provisions
      of
      the Indenture or of any supplemental indenture or of modifying in any manner
      the
      rights of the Holders of the Notes; provided, however, that no such supplemental
      indenture shall (i) extend the fixed maturity of any Notes of any series, or
      reduce the principal amount thereof, or reduce the rate or extend the time
      of
      payment of interest thereon, or reduce any premium payable upon the redemption
      thereof, or reduce the amount of the principal of a Discount Security that
      would
      be due and payable upon a declaration of acceleration of the maturity thereof
      pursuant to the Indenture, without the consent of the holder of each Note then
      outstanding and affected; (ii) reduce the aforesaid percentage of Notes, the
      holders of which are required to consent to any such supplemental indenture,
      or
      reduce the percentage of Notes, the holders of which are required to waive
      any
      default and its consequences, without the consent of the holder of each Note
      then outstanding and affected thereby; or (iii) modify any provision of Section
      6.01(c) of the Indenture (except to increase the percentage of principal amount
      of securities required to rescind and annul any declaration of amounts due
      and
      payable under the Notes), without the consent of the holder of each Note then
      outstanding and affected thereby. The Indenture also contains provisions
      permitting the Holders of a majority in aggregate principal amount of the Notes
      of all series at the time outstanding affected thereby, on behalf of the Holders
      of the Notes of such series, to waive any past default in the performance of
      any
      of the covenants contained in the Indenture, or established pursuant to the
      Indenture with respect to such series, and its consequences, except a default
      in
      the payment of the principal of or premium, if any, or interest on any of the
      Notes of such series. Any such consent or waiver by the registered Holder of
      this Note (unless revoked as pro-vided in the Indenture) shall be conclusive
      and
      binding upon such Holder and upon all future Holders and owners of this Note
      and
      of any Note issued in exchange herefor or in place hereof (whether by
      registration of transfer or otherwise), irrespective of whether or not any
      notation of such consent or waiver is made upon this Note.

    


    No
      reference herein to the Indenture and no provision of this Note or of the
      Indenture shall alter or impair the obligation of the Company, which is absolute
      and unconditional, to pay the principal of and premium, if any, and interest
      on
      this Note at the time and place and at the rate and in the money herein
      prescribed.

    


    As
      provided in the Indenture and subject to certain limitations therein set forth,
      this Note is transferable by the registered holder hereof on the Security
      Register of the Company, upon surrender of this Note for registration of
      transfer at the office or agency of the Company as may be designated by the
      Company accompanied by a written instrument or instruments of transfer in form
      satisfactory to the Company or the Trustee duly executed by the registered
      Holder hereof or his or her attorney duly authorized in writing, and thereupon
      one or more new Notes of authorized denominations and for the same aggregate
      principal amount and series will be issued to the designated transferee or
      transferees. No service charge will be made for any such trans-fer, but the
      Company may require payment of a sum sufficient to cover any tax or other
      governmental charge payable in relation thereto.

    


    Prior
      to
      due presentment for registration of transfer of this Note, the Company, the
      Trustee, any paying agent and any Security Registrar may deem and treat the
      registered Holder hereof as the absolute owner hereof (whether or not this
      Note
      shall be overdue and notwithstanding any notice of ownership or writing hereon
      made by anyone other than the Security Registrar) for the purpose of receiving
      payment of or on account of the principal hereof and premium, if any, and
      interest due hereon and for all other purposes, and neither the Company nor
      the
      Trustee nor any paying agent nor any Security Registrar shall be affected by
      any
      notice to the contrary.

    


    No
      recourse shall be had for the payment of the principal of or the interest on
      this Note, or for any claim based hereon, or otherwise in respect hereof, or
      based on or in respect of the Indenture, against any incorporator, stockholder,
      officer or director, past, present or future, as such, of the Company or of
      any
      predecessor or successor corporation, whether by virtue of any constitution,
      statute or rule of law, or by the enforcement of any assessment or penalty
      or
      otherwise, all such liability being, by the acceptance hereof and as part of
      the
      consideration for the issuance hereof, expressly waived and
      released.

    


    The
      Notes
      of this series are issuable only in registered form without coupons in
      denominations of $1,000 and any integral multiple thereof. As provided in the
      Indenture and subject to certain limitations, Notes of this series are
      exchangeable for a like aggregate principal amount of Notes of this series
      of a
      different authorized denomination, as requested by the Holder surrendering
      the
      same.

    


    All
      terms
      used in this Note which are defined in the Indenture shall have the meanings
      assigned to them in the Indenture.

    


    This
      Note
      shall not be entitled to any benefit under the Indenture hereinafter referred
      to, be valid or become obligatory for any purpose until the Certificate of
      Authentication hereon shall have been signed by or on behalf of the
      Trustee.

    


    


    IN
      WITNESS WHEREOF, the Company has caused this Instrument to be
      executed.
