          Order for the authentication and delivery of the Senior Notes pursuant
          to Section 2.04 of the Original Indenture. Such aggregate principal
          amount of the 5.75% Senior Notes Due August 16, 2007 may be increased

          issued in definitive fully registered form (the "Registered
          Securities"), without coupons, in substantially the form set out in
          Exhibit A hereto. The entire principal amount of the Senior Notes

          Purchase Contract Agreement, are no longer part of Equity Units shall
          be represented initially by Global Securities (as defined below). Each
          such Registered Security and Global Security shall represent such

          increased or

                                       4



          decreased, as applicable, to reflect Transfers from Pledged Notes to
          Separate Notes and Transfers from Separate Notes to Pledged Notes. Any
          such increase or decrease in the aggregate principal amount of (i)
          Registered Securities shall be made by the Collateral Agent and (ii)

          SECTION 1.3.    Payment of Principal and Interest.

               (a)  The unpaid principal amount of the Senior Notes shall
          initially bear interest at the rate of 5.75% per annum, payable on
          each February 16, May 16, August 16 and November 16 (each, with
          respect to the Senior Notes, an "Interest Payment Date"), from the
          original date of issuance, to, but excluding, the earlier of (i) the
          settlement date of a successful Remarketing under the Forward Purchase
          Contract Agreement or (ii) the Stock Purchase Date, and, thereafter,
          at the Reset Rate to, but excluding, the Stated Maturity of the Senior
          Notes.

               (b)  Interest shall be payable quarterly in arrears on each
          Interest Payment Date to the Person in whose name the Senior Notes are
          registered on the Regular Record Date for such Interest Payment Date;
          provided that interest payable on the Stated Maturity of principal as
          provided herein shall be paid to the person to whom principal is
          payable. Any such interest not punctually paid or duly provided for
          with respect to any Interest Payment Date falling after the Stock
          Purchase Date shall forthwith cease to be payable to the registered
          holders on such regular record date, and may be paid to the person or
          persons in whose name the Senior Notes are registered at the close of
          business on a special record date to be fixed by the Trustee for the
          payment of such defaulted interest, notice whereof shall be given to
          the registered holders of the Senior Notes not less than ten (10) days
          prior to such special record date, or may be paid at any time in any
          other lawful manner not inconsistent with the requirements of any
          securities exchange, if any, on which the Senior Notes may be listed,
          and upon such notice as may be required by such exchange, all as more
          fully provided in Section 2.03 of the Original Indenture.

               (c)  The amount of interest payable for any period will be
          computed (1) for any quarterly period, on the basis of a 360-day year
          of twelve 30-day months, (2) for any period shorter than a full
          quarterly period, on the basis of a 30-day month and (3) for periods
          of less than a month, on the basis of the actual number of days
          elapsed per 30-day month. If any date on which principal or interest
          is payable is not a Business Day, then payment of principal or
          interest payable on such date will be made on the next succeeding day
          which is a Business Day (and without any interest or other payment in
          respect of any such delay), except that, if such Business Day is in
          the next succeeding calendar year, such payment shall be made on the
          immediately preceding Business Day, in each case with the same force
          and effect as if made on such date.

               (d)  Payment of the principal of and interest on the Senior Notes
          shall be made at an Office or Agency of the Company or at the Office
          of the Agent in The City of New York in such coin or currency of the
          United States of America as at the time of payment

                                       5



          is legal tender for payment of public and private debts, with any such
          payment that is due on the Stated Maturity of any Senior Notes being
          made upon surrender of such Senior Notes to the Office or Agency of
          the Company or at the Office of the Agent in The City of New York.
          Payments of interest will be made, subject to such surrender where
          applicable, at the option of the Company, (i) by check mailed to the
          address of the person entitled thereto as such address shall appear in
          the Security Register or (ii) by wire transfer at such place and to
          such account at a banking institution in the United States as may be
          designated in writing to the Trustee at least sixteen (16) days prior
          to the date for payment by the Person entitled hereto.

          SECTION 1.4.    Denominations. The Senior Notes shall be issued in
denominations of $50 and integral multiples of $50.

          SECTION 1.5.    Global Securities.

               (a)  The Senior Notes that, in accordance with the Forward
          Purchase Contract Agreement, are no longer part of the Equity Units
          will be issued initially in the form of one or more global securities
          (the "Global Securities") registered in the name of DTC or its
          nominee. Except under the limited circumstances described below or in
          Section 1.3 above, Senior Notes represented by such Global Securities
          will not be exchangeable for, and will not otherwise be issuable as,
          Senior Notes in definitive form. The Global Securities described above
          may not be transferred except by DTC to a nominee of DTC or by a
          nominee of DTC to DTC or another nominee of DTC or to a successor
          Depository or its nominee.

               (b)  Owners of beneficial interests in such a Global Security
          will not be considered the Holders thereof for any purpose under the
          Indenture, and no Global Security representing a Senior Note shall be
          exchangeable, except for another Global Security of like denomination
          and tenor to be registered in the name of DTC or its nominee or to a
          successor Depository or its nominee or except as described below. The
          rights of owners of beneficial interests in such a Global Security
          shall be exercised only through DTC.

               (c)  A Global Security shall be exchangeable for Senior Notes
          registered in the names of persons other than DTC or its nominee only
          if (i) DTC notifies the Company that it is unwilling or unable to
          continue as a Depository for such Global Security and no successor
          Depository shall have been appointed by the Company within 90 days of
          receipt by the Company of such notification, or if at any time DTC
          ceases to be a clearing agency registered under the Securities
          Exchange Act of 1934 at a time when DTC is required to be so
          registered to act as such Depository and no successor Depository shall
          have been appointed by the Company within 90 days after it becomes
          aware of such cessation, or (ii) the Company in its sole discretion
          determines that it no longer has any senior debt securities
          represented by global securities or that it will permit a Global
          Security to be exchangeable or an Event of Default under the Indenture
          has occurred and is continuing. Any Global Security that is
          exchangeable pursuant to the preceding

                                       6



          sentence shall be exchangeable for Senior Notes registered in such
          names as DTC shall direct.

          SECTION 1.6.    Remarketing.

               (a)  The Pledged Notes comprising part of Equity Units and the
          Separate Notes of holders of Separate Notes that have elected to
          participate in the Remarketing shall be remarketed by the Remarketing
          Agent on the Remarketing Date. A Holder of Equity Units may elect not
          to participate in a Remarketing and retain the Senior Notes underlying
          such Equity Units by notifying the Forward Purchase Contract Agent of
          such election and delivering the Opt-out Treasury Consideration to the
          Forward Purchase Contract Agent not later than 10:00 a.m. on the
          fourth Business Day prior to the Remarketing Date, as applicable (or,
          in the case of a Failed Remarketing, not later than 10:00 a.m. on the
          fourth Business Day immediately prior to the subsequent Remarketing
          Period). Upon receipt thereof by the Forward Purchase Contract Agent,
          the Forward Purchase Contract Agent shall deliver such Opt-out
          Treasury Consideration to the Collateral Agent, which will, for the
          benefit of the Company, thereupon apply such Opt-out Treasury
          Consideration to secure such Holder's obligations under the Forward
          Purchase Contracts. On the first Business Day immediately preceding
          the Remarketing Date (or, in the case of a Failed Remarketing, the
          subsequent Remarketing Period), the Collateral Agent, pursuant to the
          terms of the Pledge Agreement, will deliver the Pledged Notes to the
          Forward Purchase Contract Agent. Within three Business Days following
          any Remarketing Period (A) if the Remarketing was successful, the
          Forward Purchase Contract Agent shall distribute such Notes to the new
          Holders thereof and (B) if there was a Failed Remarketing, the Forward
          Purchase Contract Agent will deliver such Notes to the Collateral
          Agent, which will, for the benefit of the Company, thereupon apply
          such Notes that are a component of Equity Units to secure such
          Holders' obligations under the Forward Purchase Contracts, return any
          Opt-out Treasury Consideration delivered by such Holders to such
          Holders and return the Separate Notes to the holders thereof. A Holder
          that does not so deliver the Opt-out Treasury Consideration or has not
          settled the related Purchase Contract through a Cash Settlement or an
          Early Settlement pursuant to Sections 5.4 and 5.9 of the Forward
          Purchase Contract Agreement shall be deemed to have elected to
          participate in the Remarketing.

               (b)  On the seventh Business Day prior to the Remarketing Date or
          the first day of any subsequent Remarketing Period, the Company shall
          give Holders of Equity Units and Holders of Separate Notes notice of
          the Remarketing in an Authorized Newspaper, including the specific
          U.S. Treasury security or securities (including the CUSIP number
          and/or the principal terms of such Treasury security or securities)
          that must be delivered by Holders of Equity Units that elect not to
          participate in the Remarketing pursuant to Section 5.4(g) of the
          Forward Purchase Contract Agreement, no later than 10:00 a.m. (New
          York City time) on the seventh Business Day preceding the Remarketing
          Date. Not later than seven nor more than 15 calendar days prior to any
          Remarketing Period, the Company shall request DTC (or any successor
          Clearing Agency) to notify, directly or indirectly, each Beneficial
          Owner or Clearing Agency Participant holding Equity Units or Stripped
          Units and each Beneficial Owner of a Separate Note of

                                       7



          the Remarketing and of the procedures that must be followed in
          connection with the Remarketing.

               (c)  The Forward Purchase Contract Agent shall notify, by 10:00
          a.m., New York City time, on the third Business Date preceding the
          Remarketing Date or the first day of any subsequent Remarketing
          Period, as applicable, the Remarketing Agent and the Collateral Agent
          of the aggregate number of Senior Notes of Equity Units Holders to be
          remarketed. On the third Business Day immediately preceding the
          Remarketing Date or the first day of any subsequent Remarketing
          Period, as applicable, no later than by 10:00 a.m. New York City time,
          pursuant to the terms of the Pledge Agreement, the Custodial Agent
          will notify the Remarketing Agent of the aggregate number of Separate
          Notes to be remarketed. On the third Business Day immediately
          preceding the Remarketing Date or the first day of any subsequent
          Remarketing Period, as applicable, the Collateral Agent and the
          Custodial Agent, pursuant to the terms of the Pledge Agreement, will
          deliver for Remarketing to the Remarketing Agent all Notes to be
          remarketed. Upon receipt of such notice from the Forward Purchase
          Contract Agent and the Custodial Agent and such Notes from the
          Collateral Agent and the Custodial Agent, the Remarketing Agent will,
          on the Remarketing Date, use its commercially reasonable best efforts
          to establish a Reset Rate pursuant to clause (i) of the definition of
          Reset Rate and remarket such Senior Notes pursuant to the Remarketing
          procedures in the Remarketing Agreement.

               (d)  The right of each Holder of Senior Notes to have its Senior
          Notes tendered for purchase will be limited to the extent that (i) the
          Remarketing Agent conducts a Remarketing pursuant to the terms of the
          Remarketing Agreement, (ii) the Remarketing Agent is able to find a
          purchaser or purchasers for the tendered Senior Notes and (iii) such
          purchaser or purchasers deliver the purchase price therefor to the
          Remarketing Agent.

               (e)  Upon receipt of the notice provided above in paragraph (c)
          from the Forward Purchase Contract Agent and the Custodial Agent and
          such Notes from the Collateral Agent and the Custodial Agent, the
          Remarketing Agent will, on the Remarketing Date, use its commercially
          reasonable best efforts to (i) establish a rate of interest that, in
          the opinion of the Remarketing Agent, will, when applied to the
          outstanding Notes, enable the then current aggregate market value of
          the Notes to have a value equal to approximately, but not less than,
          100.25% of the Remarketing Value as of the Remarketing Date or as of
          any Subsequent Remarketing Date, as the case may be (the "Reset Rate")
          and (ii) sell such Notes on such date at a price equal to
          approximately, but not less than, 100.25% of the Remarketing Value.

               (f)  If, in spite of using its commercially reasonable best
          efforts, the Remarketing Agent cannot establish the Reset Rate and
          remarket the Notes included in the remarketing at a price equal to
          approximately, but not less than, 100.25% of the Remarketing Value,
          the Remarketing Agent will again attempt to establish the Reset Rate
          and remarket the Notes included in the remarketing at a price equal to
          approximately, but not less than, 100.25% of the Remarketing Value on
          each of the two immediately following Business Days. If the
          Remarketing Agent cannot remarket the Notes included in the
          remarketing at a price equal to approximately, but not less than,
          100.25% of the

                                       8



          Remarketing Value on any of those days, it will attempt to establish
          the Reset Rate and remarket the Notes included in the remarketing at a
          price equal to approximately, but not less than, 100.25% of the
          Remarketing Value on each of the three Business Days immediately
          preceding June 16, 2005. If the Remarketing Agent cannot remarket the
          Notes included in the remarketing at a price equal to approximately,
          but not less than, 100.25% of the Remarketing Value on any of those
          days, it will attempt to establish the Reset Rate and remarket the
          Notes included in the remarketing at a price equal to approximately,
          but not less than, 100.25% of the Remarketing Value on each of the
          three Business Days immediately preceding July 16, 2005. If the
          Remarketing Agent cannot establish the Reset Rate and remarket the
          Notes included in the remarketing at a price equal to approximately,
          but not less than, 100.25% of the Remarketing Value either on any of
          the two Business Days immediately following the Remarketing Date or on
          any of the three Business Days immediately preceding June 16, 2005 or
          on any of the three Business Days immediately preceding July 16, 2005,
          the remarketing in each period will be deemed to have failed (each, a
          "Failed Remarketing"). If the Remarketing Agent cannot establish the
          Reset Rate and remarket the Notes included in the remarketing at a
          price equal to approximately, but not less than, 100.25% of the
          Remarketing Value on any of the three Business Days immediately
          preceding July 16, 2005, the Remarketing Agent will further attempt to
          establish the Reset Rate and remarket the Notes included in the
          remarketing at a price equal to approximately, but not less than,
          100.25% of the Remarketing Value on each of the three Business Days
          immediately preceding August 12, 2005. If, in spite of using its
          commercially reasonable best efforts, the Remarketing Agent fails to
          remarket the Notes underlying the Equity Units at a price equal to
          approximately, but not less than, 100.25% of the Remarketing Value in
          accordance with the terms of the Pledge Agreement by 4:00 p.m., New
          York City time, on the third Business Day immediately preceding the
          Stock Purchase Date, a "Last Failed Remarketing" will be deemed to
          have occurred.

               (g)  If a successful Remarketing shall have occurred prior to the
          fourth Business Day preceding the Stock Purchase Date, the Remarketing
          Agent will, in accordance with the Forward Purchase Contract Agreement
          and the Remarketing Agreement:

                    (i)   deduct and retain for itself the Remarketing Fee;

                    (ii)  use the proceeds from such successful Remarketing to
               purchase the Agent-purchased Treasury Consideration with the
               CUSIP numbers, if any, selected by the Remarketing Agent,
               described in clauses (1) and (2) of the definition of Remarketing
               Value related to the Senior Notes of Holders of Equity Units that
               were remarketed;

                    (iii) if any Separate Notes were remarketed, remit to the
               Collateral Agent for payment to the Holders of such Separate
               Notes sold in the Remarketing the remaining proceeds from such
               successful Remarketing attributable to the Separate Notes; and

                                       9



                    (iv)  if there remain any proceeds from such successful
               Remarketing, after the application of such proceeds as set forth
               in clauses (i) through (iii) of this sentence, then remit such
               remaining proceeds to the Forward Purchase Contract Agent for
               payment to the Holders of the Equity Units that were remarketed,
               on a pro rata basis, in accordance with the Remarketing
               Agreement.

               (h)  In the case of a successful Remarketing occurring prior to
          the fourth Business Day preceding the Stock Purchase Date, on or prior
          to the third Business Day following the Remarketing Date or any
          Subsequent Remarketing Date, the Remarketing Agent shall deliver such
          Agent-purchased Treasury Consideration to the Forward Purchase
          Contract Agent, which shall thereupon deliver such Agent-purchased
          Treasury Consideration to the Collateral Agent. The Collateral Agent,
          for the benefit of the Company, will thereupon apply such
          Agent-purchased Treasury Consideration, in accordance with the Pledge
          Agreement, to secure such Holders' obligations under the Forward
          Purchase Contracts.

               (i)  If a successful Remarketing shall have occurred on or after
          the fourth Business Day preceding the Stock Purchase Date, the
          Remarketing Agent will, in accordance with the Forward Purchase
          Contract Agreement and the Remarketing Agreement:

                    (i)   deduct and retain for itself the Remarketing Fee;

                    (ii)  pay the proceeds from such successful Remarketing to
               the Forward Purchase Contract Agent, which shall thereupon
               deliver such proceeds to the Collateral Agent which, for the
               benefit of the Company, will thereupon apply such proceeds, in
               accordance with the Pledge Agreement in direct settlement of the
               Holders' obligations under the Forward Purchase Contracts;

                    (iii) if any Separate Notes were remarketed, remit to the
               Collateral Agent for payment to the Holders of such Separate
               Notes sold in the Remarketing the remaining proceeds from such
               successful Remarketing attributable to the Separate Notes; and

                    (iv)  if there remain any proceeds from such successful
               Remarketing, after the application of such proceeds as set forth
               in clauses (i) through (iii) of this sentence, then remit such
               remaining proceeds to the Forward Purchase Contract Agent for
               payment to the Holders of the Equity Units that were remarketed,
               on a pro rata basis, in accordance with the Remarketing
               Agreement.

               (j)  If a successful Remarketing occurs, by approximately 4:30
          p.m. (New York City time) on the Remarketing Date, the Remarketing
          Agent shall advise, by telephone (promptly confirmed in writing in the
          case of clause (i)):

                    (i)   the Company, the Forward Purchase Contract Agent, the
               Collateral Agent, the Securities Intermediary, DTC and the
               Trustee of the Reset Rate

                                       10



               determined in the Remarketing;

                    (ii)  each purchaser (or the Depository Participant thereof)
               of Senior Notes in the Remarketing of the Reset Rate and the
               number of Senior Notes such purchaser is to purchase; and

                    (iii) each purchaser to give instructions to its Depository
               Participant to pay the purchase price on the date of settlement
               for such Remarketing in same day funds against delivery of the
               remarketed Senior Notes purchased through the facilities of DTC.

               (k)  Any distribution to Holders of excess funds and interest
          described in this Section 1.6 shall be payable at the Office of the
          Agent in The City of New York maintained for that purpose or, at the
          option of the Holder or the holder of Separate Notes, as applicable,
          by check mailed to the address of the Person entitled thereto at such
          address as it appears on the relevant Register or by wire transfer to
          an account specified by the Holder or the holder of Separate Notes, as
          applicable.

               (l)  If a Failed Remarketing occurs, the Remarketing Agent and
          the Company, as applicable, shall take the following actions:

                    (i)   the Remarketing Agent shall notify by telephone the
               Company, the Forward Purchase Contract Agent, the Collateral
               Agent and the Trustee, that a Failed Remarketing has occurred,
               whereupon the Company shall notify the Clearing Agency, by
               telephone, that a Failed Remarketing has occurred;

                    (ii)  with respect to any Remarketing Period during which no
               successful Remarketing occurred, the Company shall publish notice
               by means of Bloomberg and Reuters newswires, such notice to be
               published no later than the fourth Business Day following the end
               of such Remarketing Period;

                    (iii) the Remarketing Agent shall determine the Reset Rate
               in accordance with clause (ii) of the Reset Rate definition; and

                    (iv)  the Remarketing Agent shall remit, within three
               Business Days following the end of a Remarketing Period which
               constituted a Failed Remarketing, the Pledged Notes that were to
               be remarketed to the Collateral Agent and the Separate Notes that
               were to be remarketed to the Custodial Agent.

               (m)  If upon a Last Failed Remarketing, the Collateral Agent
          delivers any Senior Notes to the Company in full satisfaction of the
          Holder's obligation under the related Forward Purchase Contracts, any
          accumulated and unpaid interest on such Notes will become payable by
          the Company to the Forward Purchase Contract Agent for payment to the
          Holder of the Equity Units to which such Notes relate. Such payment
          will be made by the Company on or prior to 11:00 a.m., New York City
          time, on the Stock Purchase Date in lawful money of the United States
          by certified or cashier's check or wire transfer in immediately
          available funds payable to or upon the order of the Forward

                                       11



          Purchase Contract Agent. Upon the occurrence of a Last Failed
          Remarketing, the Company will retain and dispose of the Pledged Notes
          of all Holders in satisfaction of the Holders' obligations under the
          related Forward Purchase Contracts. The Company will publish notice by
          means of Bloomberg and Reuters newswires of any Remarketing Period
          during which no successful Remarketing occurred, such notice to be
          published not later than the fourth Business Day following the end of
          such Remarketing Period. The Company will cause a notice of the Last
          Failed Remarketing to be published on the fourth Business Day
          following the date of the Last Failed Remarketing in an Authorized
          Newspaper.

               (n)  In the event of a Last Failed Remarketing, the Remarketing
          Agent shall determine the Reset Rate that shall apply to the Senior
          Notes held by the Holders of Equity Units that elected not to
          participate in the remarketing and Holders of Separate Notes according
          to the following method, provided that in no event shall the Reset
          Rate exceed the maximum rate permitted by state usury laws and other
          applicable laws. After the Last Failed Remarketing, the Remarketing
          Agent will take the average of the interest rates quoted to it by
          three nationally recognized investment banks selected by the Company,
          which are underwriters or dealers in debt securities similar to the
          Senior Notes, that in their judgment reflects an accurate market rate
          of interest applicable to the Senior Notes at that time. Following
          receipt of these quotes, the Remarketing Agent will have the right, in
          its sole judgment, to either recalculate the average based on only two
          of the quoted interest rates if one of the three quotes, in the
          Remarketing Agent's sole discretion, did not reflect market conditions
          or, alternatively, determine a consensus among the investment banks
          rather than a strict mathematical average by taking into account all
          relevant qualitative and quantitative factors. These factors may
          include, but shall not limited to, maturity of the Senior Notes, the
          credit rating and credit risk of the Company and companies of similar
          industries, the then yield to maturity of the Senior Notes and the
          state of the markets for primary and secondary sales of similar debt
          securities.

               (o)  In accordance with DTC's normal procedures, on the date of
          settlement of such Remarketing or the Stock Purchase Date, as
          applicable, the transactions described above with respect to each
          Senior Notes remarketed in the Remarketing shall be executed through
          DTC, and the accounts of the respective Depository Participants shall
          be debited and credited and such remarketed Senior Notes delivered by
          book entry as necessary to effect purchases and sales of such
          remarketed Senior Notes. DTC shall make payment in accordance with its
          normal procedures.

               (p)  If any Holder of Senior Notes selling Senior Notes in the
          Remarketing fails to deliver such Senior Notes, the direct or indirect
          Depository Participant of such selling Holder and of any other Person
          who was to have purchased Senior Notes in the Remarketing may deliver
          to any such other Person an aggregate principal amount of Senior Notes
          that is less than the aggregate principal amount of Senior Notes that
          otherwise was to be purchased by such Person. In such event, the
          aggregate principal amount of Senior Notes to be so delivered shall be
          determined by such direct or indirect Depository Participant, and
          delivery of such lesser aggregate principal amount of Senior Notes
          shall constitute good delivery.

                                       12



               (q)  The Remarketing Agent is not obligated to purchase any
          Senior Notes that otherwise would remain unsold in the Remarketing.
          Neither the Company nor the Remarketing Agent shall be obligated in
          any case to provide funds to make payment upon tender of the Senior
          Notes for Remarketing.

               (r)  Under the Remarketing Agreement, the Company, in its
          capacity as issuer of the Senior Notes, shall be liable for, and shall
          pay, any and all costs and expenses incurred in connection with the
          Remarketing, other than the Remarketing Fee.

               (s)  The settlement procedures set forth herein, including
          provisions for payment by purchasers of the remarketed Senior Notes in
          the Remarketing, shall be subject to modification to the extent
          required by DTC or if the book-entry system is no longer available for
          the remarketed Senior Notes at the time of the Remarketing, to
          facilitate the Remarketing of the remarketed Senior Notes in
          certificated form, and shall provide for the authentication and
          delivery of Senior Notes in a principal amount equal to the
          unremarketed portion of such Senior Notes. In addition, the
          Remarketing Agent may modify the settlement procedures set forth
          herein in order to facilitate the settlement process.

          SECTION 1.7.    Optional Remarketing.

               (a)  On or prior to the fourth Business Day immediately preceding
          either the Remarketing Date or if applicable, the first day of any
          subsequent Remarketing Period, but no earlier than the Interest
          Payment Date immediately preceding the last Interest Payment Date
          before the Stock Purchase Date, holders of Separate Notes may elect to
          have their Separate Notes remarketed by Transferring their Separate
          Notes and delivering a notice of such election, substantially in the
          form of Exhibit C to the Pledge Agreement, to the Collateral Agent. On
          the third Business Day immediately prior to the Remarketing Date or
          the first day of any subsequent Remarketing Period, by 10:00 a.m., New
          York City time, the Collateral Agent shall notify the Remarketing
          Agent of the number of such Separate Notes to be remarketed. The
          Collateral Agent will hold such Separate Notes in an account separate
          from the Collateral Account. A holder of Separate Notes electing to
          have its Separate Notes remarketed will also have the right to
          withdraw such election by written notice to the Collateral Agent,
          substantially in the form of Exhibit D to the Pledge Agreement, on or
          prior to the fourth Business Day immediately preceding the applicable
          Remarketing Date or the first day of a subsequent Remarketing Period,
          upon which notice the Collateral Agent will return such Separate Notes
          to such holder.

               (b)  On the third Business Day immediately preceding the
          Remarketing Date or the first day of any subsequent Remarketing
          Period, the Collateral Agent at the written direction of the
          Remarketing Agent will deliver to the Remarketing Agent for
          Remarketing all Separate Notes delivered to the Collateral Agent
          pursuant to Section 4.5(d) of the Pledge Agreement and not withdrawn
          pursuant to the terms thereof prior to such date. If the holder of the
          Separate Notes delivers only such notice but not the Separate Notes
          subject to such notice, then none of such holder's Separate Notes
          shall be included in the Remarketing. Once the holder of Separate
          Notes elects to participate in

                                       13



          the Remarketing, such Separate Notes will be remarketed in the
          Remarketing, unless such notice is properly withdrawn. In accordance
          with Section 4.5(d) of the Pledge Agreement, upon the occurrence of a
          Failed Remarketing, the Remarketing Agent will promptly return such
          Separate Notes to the Collateral Agent for redelivery to such holders
          of such Separate Notes.

          SECTION 1.8.    Sinking Fund.  The Senior Notes shall not be entitled
to any sinking fund.

          SECTION 1.9.    Redemption and Repurchase. Except as provided in
Section 1.12, the Senior Notes shall not be redeemable prior to their Stated
Maturity.

          SECTION 1.10.   Covenants.

               (a)  For so long as any Senior Notes of this series remain
          outstanding, the Company will not create or incur or allow any of its
          subsidiaries to create or incur any pledge or security interest on any
          of the capital stock of a Public Utility Subsidiary held by the
          Company or one of its subsidiaries or a Significant Subsidiary.

          For purposes of this covenant:

                    (i)   Public Utility Subsidiary means, at any particular
               time, a direct or indirect subsidiary of the Company that, as a
               substantial part of its business, distributes or transmits
               electric energy to retail or wholesale customers at rates or
               tariffs that are regulated by either a state or Federal
               regulatory authority.

                    (ii)  Significant Subsidiary means, at any particular time,
               any direct subsidiary of the Company whose consolidated gross
               assets or consolidated gross revenues (having regard to the
               Company's direct beneficial interest in the shares, or the like,
               of that subsidiary) represent at least 25% of the Company's
               consolidated gross assets or consolidated gross revenues
               appearing in the most recent audited financial statements of the
               Company as of the date of determination.

               (b)  The provisions of Article Ten of the Original Indenture
          shall be applicable to the Senior Notes.

          SECTION 1.11.   Defeasance.  The provisions of Section 11.01 of the
Original Indenture shall not apply to the Senior Notes.

          SECTION 1.12.   Tax Event Redemption.

               (a) If a Tax Event shall occur, the Company may, at its
          option, redeem the

                                       14



          Senior Notes in whole (but not in part) at any time at a price per
          Senior Note equal to the Redemption Price. Installments of interest on
          the Senior Notes that are due and payable on or prior to the date of
          redemption (the "Tax Event Redemption Date") will be payable to the
          Holders of the Senior Notes registered as such on the Record Date next
          preceding such Tax Event Redemption Date. If, following the settlement
          of the Forward Purchase Contracts and following the occurrence of a
          Tax Event, the Company, at its option, redeems the Senior Notes, the
          proceeds of the redemption will be payable in cash to the Holders of
          the Senior Notes.

               (b)  If the Company exercises its option to redeem the Senior
          Notes following the occurrence of a Tax Event prior to the Remarketing
          Date, or if there has not been a successful Remarketing prior to the
          Stock Purchase Date, the Company shall in the notice to the Trustee
          pursuant to Section 3.02 of the Original Indenture specify the
          Redemption Price. Upon the specification of the Redemption Price by
          the Company, the Company shall appoint the Collateral Agent to acquire
          the Treasury Portfolio in consultation with the Company and in
          accordance with the Forward Purchase Contract Agreement. The
          Collateral Agent shall then apply, out of the aggregate Redemption
          Price for the Senior Notes that are components of Equity Units, an
          amount equal to the aggregate Redemption Amount for the Senior Notes
          that are components of Equity Units to purchase on behalf of the
          Holders of Equity Units the Treasury Portfolio and promptly remit the
          remaining portion, if any, of such aggregate Redemption Price to the
          Forward Purchase Contract Agent for payment to the Holders of such
          Equity Units. The Treasury Portfolio will be substituted for the
          Pledged Notes, and will be pledged to the Collateral Agent in
          accordance with the terms of the Pledge Agreement to secure the
          obligation of each Holder of an Equity Unit to purchase the Common
          Stock under the Forward Purchase Contract constituting a part of such
          Equity Units. Payment of the Redemption Price to Holders of Separate
          Notes shall be made in cash on the Tax Event Redemption Date.

               (c)  If a Tax Event Redemption occurs after the earlier of a
          successful Remarketing or the Stock Purchase Date, payment of the
          Redemption Price to each Holder of Senior Notes shall be made by the
          Trustee (subject to its receipt of funds), no later than 12:00 noon,
          New York City time, on the Tax Event Redemption Date, by check or wire
          transfer in immediately available funds (provided the necessary wire
          instructions have been provided to the Trustee at least 15 days prior
          to the Tax Event Redemption Date) at such place and to such account as
          may be designated by each such Holder of Senior Notes, including the
          Collateral Agent. If the Trustee holds immediately available funds
          sufficient to pay the Redemption Price of the Senior Notes, then, on
          such Tax Event Redemption Date, such Senior Notes will cease to be
          Outstanding.

               (d)  The Trustee shall have no duty or liability to determine or
          verify the Redemption Price. Notice of any redemption will be mailed
          at least 30 days but not more than 60 days before the Tax Event
          Redemption Date to each registered Holder of the Senior Notes to be
          repaid at its registered address. Unless the Company defaults in
          payment of the Redemption Price, on and after the Tax Event Redemption
          Date interest shall cease to accrue on the Senior Notes, whether or
          not such Senior Notes have been received by the Company, and all other
          rights of the Holders in respect of the Senior Notes shall terminate
          and lapse (other than the right to receive the Redemption Price

                                       15



          upon delivery of such Senior Notes but without interest on such
          Redemption Price).

          SECTION 1.13.   Tax Treatment. The Company agrees, and by acceptance
of a beneficial ownership interest in the Senior Notes, each beneficial holder
of Senior Notes will be deemed to have agreed (1) to treat the acquisition of an
Equity Unit as the acquisition of the Senior Note and the Forward Purchase
Contract constituting the Equity Unit and to allocate the purchase price of the
Equity Unit between the Senior Note and the Forward Purchase Contract as $50 and
$0, respectively, (2) to treat the Senior Notes as indebtedness that is subject
to Treas. Reg. Sec. 1.1275-4 (the "Contingent Payment Regulations") for United
States federal income tax purposes and (3) to be bound by the Company's
determination of the "comparable yield" and "projected payment schedule," within
the meaning of the Contingent Payment Regulations, with respect to the Senior
Notes for United States federal income tax purposes. A Holder of Senior Notes
may obtain the amount of original issue discount, issue date, yield to maturity,
comparable yield and projected payment schedule by submitting a written request
for it to the Company at the following address: American Electric Power,
Investor Relations, One Riverside Plaza, Columbus, Ohio 43215.

Third Supplemental Indenture or in any Senior Note shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                      American Electric Power Company, Inc.

                     5.75% Senior Notes Due August 16, 2007

               This Senior Note is one of a duly authorized issue of securities
of the Company (the "Securities"), issued and to be issued in one or more series
under an Indenture, dated as of May 1, 2001 (the "Original Indenture"), as
previously supplemented and as to be supplemented by a third supplemental
indenture, dated as of June 11, 2002 (the "Third Supplemental Indenture" and the
Original Indenture, as so supplemented, the "Indenture"), between the Company
and The Bank of New York, a New York banking corporation, as trustee (the
"Trustee," which term includes any successor trustee under the Indenture), and
reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders and of the terms upon which the Securities are, and
are to be, authenticated and delivered. This Senior Note is one of a series
designated as 5.75% Senior Notes Due August 16, 2007 of the Company (hereinafter
called the "Senior Notes"), issued under the Original Indenture, which is
limited in aggregate principal amount to $300,000,000.

               Neither the Original Indenture nor the Senior Notes limit or
otherwise restrict the amount of indebtedness which may be incurred or other
securities which may be issued by the Company. The Senior Notes issued under the
Indenture are direct, unsecured obligations of the Company and will mature on
August 16, 2007. The Senior Notes rank on parity with all other unsecured,
unsubordinated indebtedness of the Company.

               The Senior Notes will bear interest as set forth on the face
hereof and in the Third Supplemental Indenture. The Reset Rate will be the
interest rate per annum that is determined by the Remarketing Agent pursuant to
the Remarketing Agreement as follows: (i) in connection with a successful
Remarketing, the rate of interest that will, when applied to the Outstanding
Notes, enable the then current aggregate market value of the Notes to have a
value equal to approximately, but not less than, 100.25% of the Remarketing
Value as of the Remarketing Date or as of any Subsequent Remarketing Date, as
the case may be, or (ii) upon the occurrence of a Failed Remarketing the rate of
interest applicable to the Senior Notes initially until (A) the Senior Notes are
successfully remarketed pursuant to the Forward Purchase Contract Agreement and
the Remarketing Agreement or (B) if the Last Failed Remarketing shall have
occurred, in accordance with the method as described below.

               Notwithstanding anything herein to the contrary, the Reset Rate
shall in no event exceed the maximum rate, if any, permitted by applicable law.

               In the event of a Last Failed Remarketing, the Remarketing Agent
shall determine the Reset Rate that shall apply to the Senior Notes held by the
Holders of Equity Units that elected not to participate in the remarketing and
Holders of Separate Notes according to the following method. After the Last
Failed Remarketing, the Remarketing Agent will take the average of the interest
rates quoted to it by three nationally recognized investment banks selected

                                      A-5



by the Company, which are underwriters or dealers in debt securities similar to
the Senior Notes, that in their judgment reflects an accurate market rate of
interest applicable to the Senior Notes at that time. Following receipt of these
quotes, the Remarketing Agent will have the right, in its sole judgment, to
either recalculate the average based on only two of the quoted interest rates if
one of the three quotes, in the Remarketing Agent's sole discretion, did not
reflect market conditions or, alternatively, determine a consensus among the
investment banks rather than a strict mathematical average by taking into
account all relevant qualitative and quantitative factors. These factors may
include, but shall not limited to, maturity of the Senior Notes, the credit
rating and credit risk of the Company and companies of similar industries, the
then yield to maturity of the Senior Notes and the state of the markets for
primary and secondary sales of similar debt securities.

               The Senior Notes are not redeemable prior to maturity except
pursuant to a Tax Event in accordance with the Third Supplemental Indenture. If
a Tax Event shall occur, the Company may, at its option, redeem the Senior Notes
in whole (but not in part) at any time at a price per Senior Note equal to the
Redemption Price. Installments of interest on the Senior Notes that are due and
payable on or prior to the date of redemption will be payable to the Holders of
the Senior Notes registered as such at the close of business on the Record Date
next preceding such Tax Event Redemption Date. If, following the settlement of
the Forward Purchase Contracts and following the occurrence of a Tax Event, the
Company, at its option, redeems the Senior Notes, the proceeds of the redemption
will be payable in cash to the Holders of the Senior Notes.

               The Company agrees, and by acceptance of a beneficial ownership
interest in the Senior Notes, each beneficial holder of Senior Notes will be
deemed to have agreed (1) for United States federal, state and local income and
franchise tax purposes to treat the acquisition of an Equity Unit as the
acquisition of the Senior Note and the Forward Purchase Contract constituting
the Equity Unit, (2) to treat the Senior Notes as indebtedness that is subject
to Treas. Reg. Sec. 1.1275-4 (the "Contingent Payment Regulations") for United
States federal income tax purposes and (3) to be bound by the Company's
determination of the "comparable yield" and "projected payment schedule," within
the meaning of the Contingent Payment Regulations, with respect to the Senior
Notes for United States federal income tax purposes. A Holder of Senior Notes
may obtain the amount of original issue discount, issue date, yield to maturity,
comparable yield and projected payment schedule by submitting a written request
for it to the Company at the following address: American Electric Power,
Investor Relations, One Riverside Plaza, Columbus, Ohio 43215.

               The Senior Notes are not entitled to any sinking fund.

               The Senior Notes that are a component of Equity Units or that so
elect under Section 1.7 of the Indenture will be subject to Remarketing and, in
the case of a Failed Remarketing, the Collateral Agent for the benefit of the
Company reserves all of its rights as a secured party of the Pledged Notes with
respect thereto and, subject to applicable law and Section 5.4 of the Forward
Purchase Contract Agreement, may, among other things, permit the Company to
cause the Senior Notes to be sold or to retain and cancel such Senior Notes, in
either case, in full satisfaction of the Holders' obligations under the Forward
Purchase Contracts.

                                      A-6



               If an Event of Default with respect to the Senior Notes shall
occur and be continuing, the principal of the Senior Notes may be declared due
and payable in the manner and with the effect provided in the Indenture. The
Senior Indenture provides that in certain circumstances such declaration and its
consequences may be waived by the Holders of a majority in aggregate principal
amount of the Senior Notes then Outstanding. However, any such consent or waiver
by the Holder shall not affect any subsequent default or impair any right
consequent thereon.

               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 Securities of all series affected by such
supplemental indenture or indentures at the time outstanding voting as one
class, 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 Securities; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Securities 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 Senior Note then outstanding and
affected; (ii) reduce the aforesaid percentage of Senior Notes, the holders of
which are required to consent to any such supplemental indenture, or reduce the
percentage of Senior Notes, the holders of which are required to waive any
default and its consequences, without the consent of the holder of each Senior
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 Senior Notes), without the consent of the holder of
each Senior Note then outstanding and affected thereby. The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal
amount of the Senior Notes of any series at the time outstanding affected
thereby, on behalf of the Holders of the Senior 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
provided 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.
