year consisting of twelve 30-day months) at the Treasury Rate (as defined below)

                  date, the rate per annum equal to the semi-annual equivalent

                  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

                  in pricing new issues of corporate debt securities of
                  comparable maturity to the remaining term of the Series E

                  Government Securities" or (ii) if such release (or any

                  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.

                  SECTION 2.05.  Limitation on Secured Debt

                  So long as any of the Series E Notes are outstanding, the
Company will not create or suffer to be created or to exist any additional
mortgage, pledge, security interest, or other lien (collectively "Liens") on any
utility properties or tangible assets now owned or hereafter acquired to secure
any indebtedness for borrowed money ("Secured Debt"), without providing that
such Series E Notes will be similarly secured. Further, this restriction on
Secured Debt does not apply to the Company's existing first mortgage bonds that
have previously been issued under its mortgage indenture or any indenture
supplemental thereto; provided that this restriction will apply to future
issuances thereunder (other than issuances of refunding first mortgage bonds).
In addition, this restriction does not prevent the creation or existence of:

(i)  Liens on property  existing at the time of acquisition or  construction  of
     such  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;

(ii) Financing of the Company's accounts receivable for electric service;

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

(iv) 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 or otherwise) appearing on the Company's balance sheet, net of
applicable 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), less
the aggregate of the Company's current liabilities appearing on such balance
sheet.

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

                  SECTION 2.06.  Global Securities and Certificated Securities

                  The Series E Notes shall be issued in the form of a Global
Note in definitive, fully registered form. The Depositary for the Global Note
shall be The Depository Trust Company. The procedures with respect to transfer
and exchange of Global Notes shall be as set forth in the form of Note attached
hereto.

                  SECTION 2.07.  Form of Securities

                  The Global Note shall be substantially in the form attached as
Exhibit A hereto.

                  SECTION 2.08.  Exchange of Senior Notes upon Legal Separation

                  If Legal Separation occurs, Columbus Southern Wires will be
obligated to file the Columbus Southern Wires Registration Statement and to
effect the Columbus Southern Wires Exchange Offer, offering each holder of the
Series E Notes the election to (i) retain its Series E Notes or (ii) exchange
its Series E Notes for Columbus Southern Wires Notes.

                  If a holder of a Series E Note fails to elect to retain such
note, unless otherwise required by law, such Holder will be deemed to have
exercised his option to exchange such note for a Columbus Southern Wires Note.

                  In the case of a Columbus Southern Wires Exchange Offer as set
forth above, Columbus Southern Wires will be subject, notwithstanding any other
provision hereof, with respect to timing, to the requirement that it consummate
the Columbus Southern Wires Exchange Offer within 150 days from the date of
Legal Separation. If Columbus Southern Wires fails to consummate the Columbus
Southern Wires Exchange Offer within such 150 days, special interest premium
will accrue on the Senior Notes at the rate of 0.50% per annum until the
Columbus Southern Wires Exchange Offer is consummated.

                  The transfer of all or substantially all of the Company's
Transmission and Distribution Business shall not constitute a Default or an
Event of Default with respect to the Series E Notes nor, for purposes of the
Series E Notes, shall it be deemed a sale or transfer of all or substantially
all of the Company's assets for purposes of the Indenture. Additionally, such
transfer shall not alter the terms of the Series E Notes, and the Series E Notes
shall continue to be governed by the Indenture.

                  SECTION 2.09.  Consolidation, Merger or Sale

                  Subject to Sections 2.08 and 3.04, the Company, or the
successor to the Series E Notes, as the case may be, may merge or consolidate
with any corporation or sell substantially all of its assets as an entirety as
long as the successor or purchaser expressly assumes the payment of principal,
and premium, if any, and interest on the Series E Notes or the Columbus Southern
Wires Notes, as the case may be.


                                   ARTICLE III
                            Miscellaneous Provisions

                  SECTION 3.01.  Recitals by Company

                  The recitals in this First Supplemental Indenture are made by
the Company only and not by the Trustee, and all of the provisions contained in
the Original Indenture in respect of the rights, privileges, immunities, powers
and duties of the Trustee shall be applicable in respect of Series E Notes and
of this First Supplemental Indenture as fully and with like effect as if set
forth herein in full.

                  SECTION 3.02.  Ratification and Incorporation of Original
                                 Indenture

                  As supplemented hereby, the Original Indenture is in all
respects ratified and confirmed, and the Original Indenture and this First
Supplemental Indenture shall be read, taken and construed as one and the same
instrument.

                  SECTION 3.03.  Executed in Counterparts

                  This First Supplemental Indenture may be simultaneously
executed in several counterparts, each of which shall be deemed to be an
original, and such counterparts shall together constitute but one and the same
instrument.

                  SECTION 3.04.  Applicability of Section 4.05 and Article Ten
                                 of Original Indenture

(a)      As long as the Series E Notes are outstanding, Section 4.05 and Article
         Ten of the Original Indenture shall be applicable thereto; provided,
         however, that the transfer of all or substantially all of the Company's
         Transmission and Distribution Business (whether or not the Transmission
         and Distribution Business constitutes "substantially all" of the
         Company's total assets) to Columbus Southern Wires shall not be subject
         to Section 4.05 and Article Ten of the Original Indenture. Furthermore,
         any transfer of any portion of the Company's assets will not be subject
         to Section 4.05 or Article Ten of the Original Indenture if the Company
         retains all or substantially all of its Transmission and Distribution
         Business.


(b)      To the extent the Transmission and Distribution Business is transferred
         to Columbus Southern Wires, holders of Series E Notes shall be given
         the option to either (i) retain their Series E Notes or (ii) exchange
         their Series E Notes for Columbus Southern Wires Notes pursuant to the
         Columbus Southern Wires Exchange Offer. If any holder fails to elect to
         retain its Series E Notes, unless otherwise required by law, such
         holder will be deemed to have exercised its option to exchange its
         Series E Notes for Columbus Southern Wires Notes.


         IN WITNESS WHEREOF, each party hereto has caused this instrument to be
signed in its name and behalf by its duly authorized signatories, all as of the
day and year first above written.
