     comparable to the remaining term of the 2013 Notes that would be utilized,
     at the time of selection and in accordance with customary financial

     date, (i) the average of the bid and asked prices for the Comparable
     Treasury Issue (expressed in each case as a percentage of its principal

     by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m.

exist any additional mortgage, pledge, security interest, or other lien
(collectively "Liens") on any utility properties or tangible assets now owned or
hereafter acquired by the Company or its Subsidiaries to secure any indebtedness
for borrowed money ("Secured Debt"), without providing that such 2013 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

<PAGE>

     o    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;

     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 or

charges 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.

          (a) GENERAL. The Series A Notes will be resold initially only to (i)
     QIBs in reliance on Rule 144A under the Securities Act ("Rule 144A"), (ii)
     institutional "accredited investors" as such term is defined in rule
     501(a)(1), (2),(3) and (7) of Regulation D under the Securities Act (each,
     an "Institutional Accredited Investor") and (iii) Persons other than U.S.
     Persons (as defined in Regulation S) in reliance on Regulation S under the
     Securities Act ("Regulation S"). Series A Notes may thereafter be
     transferred to, among others, QIBs, purchasers in reliance on Regulation S,
     and Institutional Accredited Investors in each case, subject to the
     restrictions on transfer set forth herein.

          (b) GLOBAL SECURITIES.

               (i) FORM. Series A Notes initially resold pursuant to Rule 144A
          shall be issued initially in the form of one or more permanent Global
          Securities in definitive, fully registered form (collectively, the
          "Rule 144A Global Security")


                                       6
<PAGE>

          and Series A Notes initially resold pursuant to Regulation S and shall
          be issued initially in the form of one or more temporary global
          securities in definitive, fully registered form (collectively, the
          "Temporary Regulation S Global Security"), in each case without
          interest coupons and with the global securities legend and restricted
          securities legend set forth in Exhibit A hereto, which shall be
          deposited on behalf of the purchasers of the Series A Notes
          represented thereby with the Securities Custodian, and registered in
          the name of the Depository or a nominee of the Depository, duly
          executed by the Company and authenticated by the Trustee as provided
          in the Indenture. Except as set forth in this Section 2.06, beneficial
          ownership interests in the Temporary Regulation S Global Security (x)
          will not be exchangeable for interests in the Rule 144A Global
          Security, the permanent global security (the "Permanent Regulation S
          Global Security"), or any other security without a legend containing
          restrictions on transfer of such security prior to the expiration of
          the Distribution Compliance Period and (y) then may be exchanged for
          interests in a Rule 144A Global Security or the Permanent Regulation S
          Global Security only upon certification that beneficial ownership
          interests in such Temporary Regulation S Global Security are owned
          either by non-U.S. persons or U.S. persons who purchased such
          interests in a transaction that did not require registration under the
          Securities Act.

          The Rule 144A Global Security, the Temporary Regulation S Global
     Security and the Permanent Regulation S Global Security are collectively
     referred to herein as "Global Securities". The aggregate principal amount
     of the Global Securities may from time to time be increased or decreased by
     adjustments made on the records of the Trustee and the Depository or its
     nominee as hereinafter provided.

               (ii) BOOK-ENTRY PROVISIONS. This Section shall apply only to a
          Global Security deposited with or on behalf of the Depository. The
          Company shall execute and the Trustee shall, in accordance with this
          Section 2.06(b)(ii), authenticate and deliver initially one or more
          Global Securities that (a) shall be registered in the name of the
          Depository for such Global Security or Global Securities or the
          nominee of such Depository and (b) shall be delivered by the Trustee
          to such Depository or pursuant to such Depository's instructions or
          held by the Trustee as custodian for the Depository.

          Members of, or participants in, the Depository ("Agent Members") shall
     have no rights under this Indenture with respect to any Global Security
     held on their behalf by the Depository or by the Trustee as the custodian
     of the Depository or under such Global Security, and the Company, the
     Trustee and any agent of the Company or the Trustee shall be entitled to
     treat the Depository as the absolute owner of such Global Security for all
     purposes whatsoever. Notwithstanding the foregoing, nothing herein shall
     prevent the Company, the Trustee or any agent of the Company or the Trustee
     from giving effect to any written certification, proxy or other
     authorization furnished by the Depository or impair, as between the
     Depository and its Agent Members, the operation of customary practices of
     such Depository governing the exercise of the rights of a holder of a
     beneficial interest in any Global Security.


                                       7
<PAGE>

          To the extent a notice or other communication to the beneficial owners
     of the 2013 Notes is required under the Indenture, unless and until
     Certificated Securities shall have been issued to such owners, the Trustee
     shall give all such notices and communications specified herein to be given
     to such owners to the Depository, and shall have no obligations to such
     Owners.

          (c) CERTIFICATED SECURITIES. Series A Notes sold to Institutional
     Accredited Investors shall be issued initially in the form of a fully
     registered, certificated Series A Note ("Certificated Securities"). Except
     as provided in this Section 2.06, owners of beneficial interests in Global
     Securities shall not be entitled to receive physical delivery of
     Certificated Securities.

     Global Securities shall be exchangeable for Certificated Securities if (i)
the Depository (x) notifies the Company that it is unwilling or unable to
continue as Depository for the Global Securities or (y) shall no longer be
registered or in good standing under the Exchange Act, or other applicable
statute or regulation, and a successor Depository for the Global Securities is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such condition. Upon surrender to the Trustee of the
typewritten certificate or certificates representing the Global Securities by
the Depository, accompanied by registration instructions, the Trustee shall
execute and authenticate the certificates in accordance with the instructions of
the Depository. Neither the Security Registrar nor the Trustee shall be liable
for any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of
Certificated Securities, the Trustee shall recognize the Holders of the
Certificated Securities as Holders. The Certificated Securities shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Company, as evidenced by the execution thereof by
the Company, and shall bear the legend set forth on Exhibit A hereto unless the

          (b) TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.

               (i) If a holder of a beneficial interest in the Rule 144A Global
          Security wishes at any time to exchange its interest in the Rule 144A
          Global Security for an interest in the Permanent Regulation S Global
          Security, or to transfer its interest in the Rule 144A Global Security
          to a person who wishes to take delivery thereof in the form of an

          such holder may, subject to the rules and procedures of the Depository

          or cause the exchange or transfer or cause the transfer of such
          interest for an equivalent beneficial interest in the Permanent
          Regulation S Global Security. Upon receipt by the Trustee, as transfer
          agent, of (1) instructions given in accordance with the Depository's
          procedures from or on behalf of a holder of a beneficial interest in
          the Rule 144A Global Security, directing the Trustee, as transfer
          agent, to credit or cause to be credited a beneficial interest in the
          Permanent Regulation S Global Security in an amount equal to the
          beneficial interest in the Rule 144A Global Security to be exchanged
          or transferred, (2) a written order given in accordance with the
          Depository's procedures containing information regarding the Euroclear
          or Clearstream account to be credited with such increase and the name
          of such account, and (3) a certificate in the form of Exhibit C hereto
          given by the holder of such beneficial interest stating that the
          exchange or transfer of such interest has been made pursuant to and in
          accordance with Rule 903 or Rule 904 of Regulation S under the
          Securities Act, the Trustee, as transfer agent, shall promptly deliver
          appropriate instructions to the Depository, its nominee, or the
          custodian for the Depository, as the case may be, to reduce or reflect
          on its records a reduction of the Rule 144A Global Security by the
          aggregate principal amount of the beneficial interest in such Rule
          144A Global Security to be so exchanged or transferred from the
          relevant participant, and the Trustee, as transfer agent, shall
          promptly deliver appropriate instructions to the Depository, its
          nominee, or the custodian for the Depository, as the case may be,
          concurrently with such reduction, to increase or reflect on its
          records an increase of the principal amount of such Permanent
          Regulation S Global Security by the aggregate principal amount of the
          beneficial interest in such Rule 144A Global Security to be so
          exchanged or transferred, and to credit or cause to be credited to the
          account of the person specified in such instructions (who may be
          Euroclear or Clearstream or another agent member of Euroclear or
          Clearstream or both, as the case may be, acting for and on behalf of
          them) a beneficial interest in such Permanent Regulation S Global
          Security equal to the reduction in the principal amount of such Rule
          144A Global Security.

               (ii) If a holder of a beneficial interest in the Permanent
          Regulation S Global Security wishes at any time to exchange its
          interest in the Permanent Regulation S Global Security for an interest
          in the Rule 144A Global Security, or to transfer its interest in the
          Permanent Regulation S Global Security to a person who wishes to take
          delivery thereof in the form of an interest in the Rule 144A Global
          Security, such holder may, subject to the rules and procedures of
          Euroclear or Clearstream and the Depository, as the case may be, and
          to the requirements set forth in the following sentence, exchange or
          cause the exchange or transfer or cause the transfer of such interest
          for an equivalent beneficial interest in such Rule 144A Global
          Security. Upon receipt by the Trustee, as transfer agent, of (1)
          instructions given in accordance with the procedures of Euroclear or
          Clearstream and the Depository, as the case may be, from or on behalf
          of a beneficial owner of an interest in the Permanent Regulation S
          Global Security directing the Trustee, as transfer agent, to credit or
          cause to be credited a beneficial interest in the Rule


                                       9
<PAGE>

          144A Global Security in an amount equal to the beneficial interest in
          the Permanent Regulation S Global Security to be exchanged or
          transferred, (2) a written order given in accordance with the
          procedures of Euroclear or Clearstream and the Depository, as the case
          may be, containing information regarding the account with the
          Depository to be credited with such increase and the name of such
          account, and (3) prior to the expiration of the Distribution
          Compliance Period, a certificate in the form of Exhibit C hereto given
          by the holder of such beneficial interest and stating that the person
          transferring such interest in such Permanent Regulation S Global
          Security reasonably believes that the person acquiring such interest
          in the Rule 144A Global Security is a QIB and is obtaining such
          beneficial interest for its own account or the account of a QIB in a
          transaction meeting the requirements of Rule 144A and any applicable
          securities laws of any state of the United States or any other
          jurisdiction, the Trustee, as transfer agent, shall promptly deliver
          appropriate instructions to the Depository, its nominee, or the
          custodian for the Depository, as the case may be, to reduce or reflect
          on its records a reduction of the Permanent Regulation S Global
          Security by the aggregate principal amount of the beneficial interest
          in such Permanent Regulation S Global Security to be exchanged or
          transferred, and the Trustee, as transfer agent, shall promptly
          deliver appropriate instructions to the Depository, its nominee, or
          the custodian for the Depository, as the case may be, concurrently
          with such reduction, to increase or reflect on its records an increase
          of the principal amount of the Rule 144A Global Security by the
          aggregate principal amount of the beneficial interest in the Permanent
          Regulation S Global Security to be so exchanged or transferred, and to
          credit or cause to be credited to the account of the person specified
          in such instructions a beneficial interest in the Rule 144A Global
          Security equal to the reduction in the principal amount of the
          Permanent Regulation S Global Security. After the expiration of the
          Distribution Compliance Period, the certification requirement set
          forth in clause (3) of the second sentence of this Section 2.08(b)(ii)
          will no longer apply to such exchanges and transfers.

               (iii) Any beneficial interest in one of the Global Securities
          that is transferred to a person who takes delivery in the form of an
          interest in the other Global Securities will, upon transfer, cease to
          be an interest in such Global Security and become an interest in the
          other Global Securities and, accordingly, will thereafter be subject
          to all transfer restrictions and other procedures applicable to
          beneficial interests in such other Global Security Note for as long as
          it remains such an interest.

               (iv) Beneficial interests in Temporary Regulation S Global
          Securities may be exchanged for interests in Rule 144A Global
          Securities or Permanent Regulation S Global Securities if (1) such
          exchange occurs in connection with a transfer of securities in
          compliance with Rule 144A, and (2) the transferor of the beneficial
          interest in the Temporary Regulation S Global Security first delivers
          to the Trustee a written certificate (in a form satisfactory to the
          Trustee) to the effect that the beneficial interest in the Temporary
          Regulation S Global Security is being transferred to a Person (a) who
          the transferor reasonably believes to be a QIB (b)


                                       10
<PAGE>

          purchasing for its own account or the account of a QIB in a
          transaction meeting the requirements of Rule 144A, and (c) in
          accordance with all applicable securities laws of the states of the
          United States and other jurisdictions.

               (v) During the Distribution Compliance Period, beneficial
          ownership interests in Temporary Regulation S Global Securities may
          only be sold, pledged or transferred through Euroclear or Clearstream
          in accordance with the applicable procedures relating to such
          institutions and only (i) to the Company, (ii) so long as such
          security is eligible for resale pursuant to Rule 144A, to a Person
          whom the selling holder reasonably believes is a QIB that purchases
          for its own account or for the account of a QIB in a transaction
          meeting the requirements of Rule 144A, (iii) in an offshore
          transaction in accordance with Regulation S (other than a transaction
          resulting in an exchange for interest in a Permanent Regulation S
          Global Security), (iv) pursuant to an exemption from registration
          under the Securities Act provided by Rule 144 (if applicable) under
          the Securities Act or (v) pursuant to an effective registration
          statement under the Securities Act, in each case in accordance with
          any applicable securities laws of any state of the United States.

          (c) TRANSFER AND EXCHANGE OF GLOBAL SECURITIES AND CERTIFICATED
     SECURITIES.

               (i) In the event that a Global Security is exchanged for a
          Certificated Security as provided in Section 2.06(c), such
          Certificated Security may be exchanged or transferred for one another,
          subject to Section 2.05 of the Original Indenture, only in accordance
          with such procedures as are substantially consistent with the
          provisions of clauses (b)(i) and (ii) above (including the
          certification requirements intended to ensure that such exchanges or
          transfers comply with Rule 144, Rule 144A or Regulation S, as the case
          may be) and as may be from time to time reasonably adopted by the
          Company.

               (ii) Upon receipt by the Trustee of a Certificated Security, duly
          endorsed or accompanied by appropriate instruments of transfer, the
          Trustee shall cancel such Certificated Security and cause, or direct
          the Securities Custodian to cause, in accordance with the standing
          instructions and procedures existing of the Depository and the
          Securities Custodian, the aggregate principal amount of 2013 Notes
          represented by the Rule 144A Global Security or Permanent Regulation S
          Global Security, as applicable, to be increased by the aggregate
          principal amount of the Certificated Security to be exchanged and
          shall credit or cause to be credited to the account of the Person
          specified in such instructions a beneficial interest in the Rule 144A
          Global Security or Permanent Regulation S Global Security, as
          applicable, equal to the principal amount of the Certificated Security
          so canceled. If no Rule 144A Global Securities or Permanent Regulation
          S Global Securities, as applicable, are then outstanding, the Company
          shall issue and the Trustee shall authenticate, upon written order of
          the Company in the form of an Officers' Certificate, a new Rule 144A
          Global Security or Permanent Regulation S Global Security, as
          applicable, in the appropriate principal amount.

          (d) CERTIFICATES. In connection with any transfer described in

     Additionally, upon any transfer or exchange to an Institutional Accredited
     Investor, the Company and the Trustee shall receive a certificate in the
     form attached as Exhibit D hereto.

          (e) TRANSFER RESTRICTED SECURITY. Upon any sale or transfer of a
     Transfer Restricted Security (including any Transfer Restricted Security
     represented by a Global Security) pursuant to Rule 144 under the Securities
     Act or an effective registration statement under the Securities Act, which
     shall be certified to the Trustee and Security Registrar upon which each
     may conclusively rely:

               (i) in the case of any Transfer Restricted Security represented
          by a Certificated Security, the Security Registrar shall permit the
          Holder thereof to exchange such Transfer Restricted Security for a
          Certificated Security that does not bear the legend set forth in
          Exhibit A hereto and rescind any restriction on the transfer of such
          Transfer Restricted Security; and

               (ii) in the case of any Transfer Restricted Security represented
          by a Global Security, such Transfer Restricted Security shall not be
          required to bear the legend set forth in Exhibit A hereto if all other
          interests in such Global Note have been or are concurrently being sold
          or transferred pursuant to Rule 144 under the Securities Act or
          pursuant to an effective registration statement under the Securities
          Act.

          (f) REGISTERED EXCHANGE OFFER. Notwithstanding the foregoing, upon
     consummation of the Registered Exchange Offer, the Company shall issue and,
     upon receipt of a Company Order in accordance with Section 2.05 of the
     Original Indenture, the Trustee shall authenticate Series B Notes in
     exchange for Series A Notes accepted for exchange in the Registered
     Exchange Offer, which Series B Notes shall not bear the transfer
     restriction legend set forth in Exhibit A hereto and shall not provide for
     Special Interest Premium and the Security Registrar shall rescind any
     restriction on the transfer of such Series B Notes, in each case unless the
     Holder of such Series A Notes (A) is a broker-dealer tendering Series A
     Notes acquired directly from the Company or an "affiliate" (as defined in
     Rule 144 under the Securities Act) of the Company for its own account, (B)
     is a Person who has an arrangement or understanding with any Person to
     participate in the "distribution" (within the meaning of the Securities
     Act) of the Series B Notes, (C) is a Person who is an "affiliate" (as
     defined in Rule 144 under the Securities Act) of the Company or (D) will
     not be acquiring the Series B Notes in the ordinary course of such Holder's
     business. The Company shall identify to the Trustee such Holders in a
     written certification signed by an Officer of the Company and, absent
     certification from the Company to such effect, the Trustee shall assume
     that there are no such Holders.

and after such Interest Payment Date, redemption date or Stated Maturity, as the
case may be, except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business

(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 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
(defined below), all issued or to be issued in one or more series under and
pursuant to an Indenture dated as of February 1, 2003 duly executed and
delivered between the Company and Bank One, N. A., a national banking
association organized and existing under the laws of the United States, 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 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 as 5.50%
Senior Notes, Series [A/B] due 2013 initially issued in the aggregate principal
amount of $225,000,000.

         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' previous notice given by mail to the registered owners of the Note
at a redemption price equal to the greater of (i) 100% of the principal of the
Note 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 25 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.


                                    Ex. A-5
<PAGE>

         "Comparable Treasury Price" means, with respect to any redemption date,
         (1) the average of the bid and asked prices for the Comparable Treasury
         Issue (expressed in each case as a percentage of its principal amount)
         on the third Business Day preceding such redemption date, as set forth
         in the daily statistical release (or any successor release) published
         by the Federal Reserve Bank of New York and designated "Composite 3:30
         p.m. Quotations for U.S. Government Securities" or (2) if such release
         (or any successor release) is not published or does not contain such
         prices on such third Business Day, the Reference Treasury Dealer
         redemption date.

         "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 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. This Note will not have a sinking fund.

         As described in the supplemental indenture relating to the Notes, so
long as this Note is outstanding, the Company is subject to a limitation on
issuance of Secured Debt as described therein.


                                    Ex. A-6
<PAGE>

         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 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 or
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 transfer, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in relation thereto.


                                    Ex. A-7
<PAGE>

         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 Note 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 released 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 except that
a Note issued to an Institutional Accredited Investor will be in denominations
of at $250,000. 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.

                        FORM OF LETTER TO BE DELIVERED BY
                       INSTITUTIONAL ACCREDITED INVESTORS

Ladies and Gentlemen:

         In connection with our proposed purchase of the 5.50% Senior Notes,
Series A due 2013 (the Notes) issued by AEP Texas North Company, a Texas
corporation (Issuer), we confirm that:

         1.   We are purchasing the Notes for our own account, or for one or
              more investor accounts for which we are acting as a fiduciary or
              agent, in each case for investment, and not with a view to, or for
              offer or sale in connection with, any distribution in violation of
              the Securities Act, subject to any requirement of law that the
              disposition of our property or the property of such investor
              account or accounts be at all times within our or their control
              and subject to our or their ability to resell the Notes pursuant
              to Rule 144A, Regulation S or any exemption from registration
              available under the Securities Act.

         2.   We are an institutional "accredited investor" within the meaning
              of Rule 50l(a)(l), (2), (3) or (7) under the Securities Act who is
              purchasing Notes with a principal amount of at least $250,000 and,
              if the Notes are to be purchased for one or more accounts (the
              "investor accounts") for which we are acting as fiduciary or
              agent, each such account is an institutional accredited investor
              who is purchasing Notes with a principal amount of at least
              $250,000. In the normal course of business or our investing
              activities, we invest in or purchase securities similar to the
              Notes and we have such knowledge and experience in financial
              business matters that we are capable of evaluating the merits and
              risks of purchasing the Notes. We are aware that we (or any
              investor account) may be required to bear the economic risk of an
              investment in the Notes for an indefinite period of time and we
              (or such investor account) are able to bear such risk for an
              indefinite period.

         3.   We acknowledge that none of the Issuer, the initial purchasers or
              any persons representing any of them has made any representation
              to us with respect to any such entity or the offering or sale of
              any Notes, other than the information contained in the Issuer's
              offering memorandum dated February 12, 2003, related to the Notes,
              which offering memorandum has been delivered to it and upon which
              it is relying in making its investment decision with respect to
              the Notes. Accordingly, we acknowledge that no representation or
              warranty is made by the initial purchasers as to the accuracy or
              completeness of such materials. We have had access to such
              financial and other information concerning the Issuer and the
              Notes as we have deemed necessary in connection with our decision
              to purchase any of the Notes including an opportunity to ask
              questions of, and request information from, the Issuer and the
              initial purchasers.

         4.   We understand and agree that the offer and sale of the Notes have
              not been registered under the Securities Act and that such Notes
              are being offered only in a transaction not involving any public
              offering within the meaning of the Securities Act, and that (A) if
              we decide to resell, pledge or otherwise transfer such Notes on
              which a legend setting forth these restrictions appears, such
              Notes may be resold, pledged or otherwise transferred only (i) to
              the Issuer, (ii) in a transaction entitled to an exemption from
              registration provided by Rule 144 under the Securities Act, (iii)
              so long as such Notes are eligible for resale pursuant to Rule
              144A, to a person whom we reasonably believe is a qualified
              institutional buyer that purchases for its own account or for the
              account of a qualified institutional buyer to whom notice is given
              that the resale, pledge or other transfer is being made in
              reliance on Rule 144A, (iv) outside the United States in a
              transaction meeting the requirements of Regulation S, (v) in
              accordance with another exemption from the registration
              requirements of the Securities Act (and based upon an opinion of
              counsel acceptable to the Issuer), in each case in accordance with
              any applicable securities laws of any state of the United States
              or (vi) pursuant to a registration statement which has been
              declared effective under the Securities Act and (B) we will, and
              each subsequent holder is required to, notify any purchaser of
              Notes from us or it of the resale restrictions referred to in (A)
              above, if then applicable. We acknowledge that the foregoing
              restrictions apply to holders of beneficial interest in the Notes,
              as well as to holders of the Notes.

         5.   We understand that, on any proposed resale of any Notes, we will
              be required to furnish to the trustee and the Issuer such
              certifications, legal opinions and other information as the
              trustee and the Issuer may reasonably require to confirm that the
              proposed sale complies with the foregoing restrictions. We further
              understand that the Notes purchased by us will bear a legend to
              the foregoing effect.

         6.   We acknowledge that the Issuer, the trustee, the initial
              purchasers and others will rely upon the truth and accuracy of the
              foregoing acknowledgements, representations and agreements and
              agree that if any of the foregoing acknowledgements,
              representations or agreements are no longer accurate, we shall
              promptly notify the Issuer, the trustee and the initial
              purchasers. If we are acquiring the Notes as a fiduciary or agent
              for one or more investor accounts, we represent that we have sole
              investment discretion with respect to each such account and we
              have full power to make the foregoing acknowledgements,
              representations and agreements on behalf of each account and that
              each such investor account is eligible to purchase the Notes.

         7.   The Issuer, the trustee and the initial purchasers are entitled to
              rely upon this letter and are irrevocably authorized to produce
              this letter or a copy hereof to any interested party in any
              administrative or legal proceeding or official inquiry with
