coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. Payments of interest
(including interest on any Interest Payment Date) 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

      SECTION 104.      Deferral of Interest Payments

      The Company has the right to defer payments of interest on the Series B
Debentures by extending the interest payment period from time to time on the

interest will continue to accrue on the Series B Debentures.

      If the Company decides to defer interest payments on the Series B
Debentures, the Extension Period shall not exceed five consecutive years. An
Extension Period shall not extend beyond the stated maturity of the Series B
Debentures. Prior to the termination of any Extension Period, the Company may
further defer payments of interest provided that the Extension Period, together
with all previous and further extensions thereof, may not exceed five
consecutive years. There could be multiple Extension Periods of varying lengths
throughout the term of the Series B Debentures. Upon the termination of any such
Extension Period and upon the payment of all accrued and unpaid interest then
due, the Company may select a new Extension Period, subject to the above
limitations and requirements. Upon the termination of any Extension Period,
which termination shall be on an Interest Payment Date, the Company shall pay
all Deferred Interest on the next succeeding Interest Payment Date to the Person
in whose name the Series B Debentures are registered on the Regular Record Date
for such Interest Payment Date, provided that Deferred Interest payable at
Stated Maturity or on any Redemption Date will be paid to the Person to whom
principal is payable.

Extension Period, the Company shall not (1) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of its capital stock, (2) make any payment of principal of
or interest or premium, if any, on or repay, repurchase or redeem any of its
debt securities that rank equally with, or junior to, the Series B Debentures,
or (3) make any guarantee payments with respect to any guarantee issued by the
Company if such guarantee ranks equally with, or junior to, the Series B
Debentures, other than, in each case, repurchases, redemptions or other
acquisitions of shares of its:

                  (i) capital stock in connection with any employment contract,

            any one or more employees, officers, directors or consultants or in
            connection with a dividend reinvestment or shareholder stock
            purchase plan;

                  (ii) as a result of an exchange or conversion of any class or
            series of the Company's capital stock, or any capital stock of a
            subsidiary of the Company, for any class or series of the Company's
            capital stock or of any class or series of the Company's then
            outstanding indebtedness for any class or series of the Company's
            capital stock;

                  (iii) the purchase of fractional interests in shares of the
            Company's capital stock pursuant to the conversion or exchange
            provisions of the capital stock or the security being converted or
            exchanged;

                  (iv) payments under any guarantee executed and delivered by
            the Company concurrently with the issuance of any Preferred
            Securities;

                  (v) any declaration of a dividend in the form of capital stock
            in connection with any shareholders' rights plan, or the issuance of
            rights to capital stock under any shareholders' rights plan, or the
            redemption or repurchase of rights pursuant to any such plan; or

                  (vi) any dividend in the form of stock, warrants, options or
            other rights where the dividend stock or the stock issuable upon
            exercise of the warrants, options or other rights is the same stock
            as that on which the dividend is being paid or ranks on a parity
            with or junior to the stock,

            with the giving of notice or the lapse of time, or both, would
            constitute an event of default under the applicable indenture, and
            (b) the Company has not taken reasonable steps to cure the same;

                  (ii) the Company is in default with respect to payment of any
            obligations under any guarantee executed and delivered concurrently

selection or extension of an Extension Period at least one Business Day prior to

registered in the name of the Depositary (which shall be The Depository Trust
Company) or its nominee. Except under the limited circumstances described below,
Series B Debentures represented by the Global Security will not be exchangeable
for, and will not otherwise be issuable as, Series B Debentures in definitive
form. The Global Securities described above may not be transferred except by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to
the Depositary or another nominee of the Depositary or to a successor Depositary
or its nominee.

      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 Series B Debenture shall be exchangeable, except
for another Global Security of like denomination and tenor to be registered in
the name of the Depositary or its nominee or to a successor Depositary or its
nominee. The rights of Holders of such Global Security shall be exercised only
through the Depositary.

      A Global Security shall be exchangeable for Series B Debentures registered
in the names of persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as a
Depositary for such Global Security and no successor Depositary shall have been
appointed, or if at any time the Depositary ceases to be a clearing agency
registered under the Exchange Act at a time when the Depositary is required to
be so registered to act as such Depositary and no successor Depositary shall
have been appointed; (ii) the Company in its sole discretion determines that
such Global Security shall be so exchangeable; or (iii) there shall have
occurred an Event of Default with respect to the Series B Debentures. Any Global
Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for Series B Debentures registered in such names as the Depositary
shall direct.

      SECTION 107.      Transfer

      No service charge will be made for any transfer or exchange of Series B
Debentures, but payment will be required of a sum sufficient to cover any tax or
other governmental charge that may be imposed in connection therewith.

      The Company shall not be required (a) to issue, transfer or exchange any
Series B Debentures during a period beginning at the opening of business fifteen
(15) days before the day of the mailing of a notice of redemption, and ending at
the close of business on the day of the mailing, or (b) to transfer or exchange
any Series B Debentures called for redemption.

      SECTION 108.      Redemption

      The Series B Debentures shall be subject to redemption at the option of
the Company, in whole, but not in part, without premium or penalty, on the last
Interest Payment Date relating to the Initial Fixed Rate Period, on such dates
with respect to any other Fixed Rate Period as the Company and the Trust may
determine prior to the remarketing establishing such Fixed Rate Period or on any
Interest Payment Date relating to a Floating Rate Period, at a Redemption Price
equal to 100% of the principal amount to be redeemed plus accrued but unpaid
interest to the Redemption Date. In addition, upon the occurrence of a Special
Event at any time, the Company may, within ninety (90) days following the
occurrence thereof and subject to the terms and conditions of the Indenture,
elect to redeem the Series B Debentures, in whole, but not in part, at a price
equal to 100% of the principal amount to be redeemed plus any accrued but unpaid
interest to the date of redemption (any date of redemption as provided for in
this paragraph herein called a "Redemption Date").

      The Series B Debentures will not have a sinking fund.

      Notice of redemption shall be given as provided in Section 404 of the
Original Indenture.

                                    ARTICLE 2
                               Interest Procedures

      Article 4 of the Trust Agreement sets forth the procedures to determine
the Distribution Rate, Distribution Periods and Distribution Payment Dates for
the Preferred Securities. While the Preferred Securities are outstanding, the
Interest Rate, Interest Periods, Interest Payment Dates and associated terms
relating to the Series B Debentures shall be the same as the Distribution Rate,
Distribution Periods and Distribution Payment Dates and associated terms
relating to the Preferred Securities. If the Trust is terminated and the Series
B Debentures are distributed to the holders of the Preferred Securities, subject
to Section 103 herein, the below described procedures will be applicable to the
Series B Debentures.

      SECTION 201.      Interest Payments

      Interest payments shall accrue from the Original Issue Date until the
Redemption Date. During the Initial Fixed Rate Period, interest will be payable
semiannually in arrears on April 1 and October 1 of each year, commencing on
April 1, 2004. During any Fixed Rate Period, other than the Initial Fixed Rate
Period, interest will be payable semiannually in arrears on Interest Payment
Dates determined based on the Remarketing Date (if the Series B Debentures are
remarketed for a new Fixed Rate Period that begins on April 1 or October 1,
interest will be payable on April 1 and October 1 of each year, and if the
Series B Debentures are remarketed for a new Fixed Rate Period that begins on
January 1 or July 1, interest will be payable on January 1 and July 1 of each
year). During any Floating Rate Period, interest will be payable quarterly in
arrears on January 1, April 1, July 1 and October 1 of each year.

      If any Interest Payment Date with respect to a Fixed Rate Period is not a
Business Day, interest will be payable, without additional interest, on the
immediately succeeding Business Day, with the same force and effect as if
payment was made on the date such payment was originally payable. If any
Interest Payment Date with respect to a Floating Rate Period is not a Business
Day, then interest will be payable on the immediately succeeding Business Day
and interest shall accrue to the actual payment date (except for an Interest
Payment Date that coincides with the Redemption Date).

      The amount of interest payable on each Interest Payment Date relating to a
Fixed Rate Period will be computed on the basis of a 360-day year of twelve
30-day months. The amount of interest payable on each Interest Payment Date in
respect of a Floating Rate Period will be computed by multiplying the per annum
Interest Rate in effect for such Interest Period by a fraction, the numerator of
which will be the actual number of days in such Interest Period (or portion
thereof) (determined by including the first day thereof and excluding the last
thereof) and the denominator of which will be 360, and multiplying the rate so
obtained by $1,000.

      Interest on the Series B Debentures will be deferred during any Extension
Period but will continue to accrue. The payment of such interest, together with
any interest thereon, will be distributed to the holders of Series B Debentures
at the end of any Extension Period.

      Interest on the Series B Debentures on each Interest Payment Date shall be
payable to the Person in whose name the Series B Debentures are registered on
the Regular Record Date.

      Each Series B Debenture upon registration of transfer of or in exchange
for or in lieu of any other Series B Debenture shall carry the rights of
interest accrued and unpaid, and to accrue, which were carried by such other
Series B Debenture.

      SECTION 202.      Interest Rate

      During the Initial Fixed Rate Period, the Interest Rate shall be the
Initial Interest Rate.

      Prior to the expiration of the Initial Fixed Rate Period and any
subsequent Fixed Rate Period or an Interest Period with respect to a Floating
Rate Period or an Interest Period in a Fixed Rate Period during a time in which
the Series B Debentures are redeemable in such Fixed Rate Period, the Company
will have the option to remarket the Series B Debentures to establish a new
Fixed Rate for a new Fixed Rate Period (to be in effect after the expiration of
the then current Interest Period). If the Company elects to conduct a
Remarketing of the Series B Debentures for the purpose of establishing a new
Fixed Rate for a new Fixed Rate Period, the Company shall not less than 20 nor
more than 35 Business Days prior to the related Election Date, notify the
Clearing Agency, the Calculation Agent, the Indenture Trustee and the
Remarketing Agent. If the Series B Debentures are not issued in global, fully
registered form to the Clearing Agency, such notice shall be delivered to the
holders of the Series B Debentures instead of the Clearing Agency. Such notice
shall indicate the length of the proposed new Fixed Rate Period, the proposed
Remarketing Date and any redemption provisions that apply during such new Fixed
Rate Period. The Company shall have the right to terminate a Remarketing at any
time prior to the Election Date by notice of such termination to the Clearing
Agency, the Remarketing Agent, the Indenture Trustee and the Calculation Agent.

      If the Remarketing Agent has determined that it will be able to remarket
all Series B Debentures tendered or deemed tendered for purchase in the
Remarketing at a Fixed Rate and at a price of $1,000 per Series B Debenture, on
such Remarketing Date, the Interest Rate for the new Fixed Rate Period will be
the Fixed Rate determined by the Remarketing Agent, which will be the rate per
annum (rounded to the nearest one-thousandth (0.001) of one percent per annum)
which the Remarketing Agent determines, in its sole judgment, to be the lowest
Fixed Rate per annum, if any, that will enable it to remarket all Series B
Debentures tendered or deemed tendered for Remarketing at a price of $1,000 per
Series B Debenture.

      If the Company does not elect to remarket the Series B Debentures or has
terminated a Remarketing or the Remarketing Agent is unable to remarket all of
the Series B Debentures tendered or deemed tendered for a purchase price of
$1,000 per Series B Debenture, the Interest Rate shall be the Floating Rate and
the new Interest Period shall be a Floating Rate Period.

            The Calculation Agent shall calculate the Floating Rate as follows:

      Except as provided below, the Floating Rate for any Floating Rate Period
for the Series B Debentures will be equal to the Adjustable Rate (as defined
below) plus 2.375%. The "Adjustable Rate" for any Interest Period will be equal
to the highest of the 3-month LIBOR Rate, the 10-year Treasury CMT and the
30-year Treasury CMT (each as defined below and collectively referred to as the
"Benchmark Rates") for such Interest Period during the Floating Rate Period. In
the event that the Calculation Agent determines in good faith that for any
reason:

                  (i) any one of the Benchmark Rates cannot be determined for
            any Interest Period, the Adjustable Rate for such Interest Period
            will be equal to the higher of whichever two of such rates can be so
            determined;

                  (ii) only one of the Benchmark Rates can be determined for any
            Interest Period, the Adjustable Rate for such Interest Period will
            be equal to whichever such rate can be so determined; or

                  (iii) none of the Benchmark Rates can be determined for any
            Interest Period, the Adjustable Rate for the preceding Interest
            Period will be continued for such Interest Period.

      The "3-month LIBOR Rate" means, for each Interest Period, the arithmetic
average of the two most recent weekly quotes for deposits for U.S. Dollars
having a term of three months, as published on the first Business Day of each
week during the relevant Calendar Period (as defined below) immediately
preceding the Interest Period for which the Floating Rate is being determined.
Such quotes will be taken from Telerate Page 3750 at approximately 11:00 a.m.
London time on the relevant date. If such rate does not appear on Telerate Page
3750 on the relevant date, the 3-month LIBOR Rate will be the arithmetic mean of
the rates quoted by three major banks in New York City selected by the
Calculation Agent, at approximately 11:00 a.m., New York City time, on the
relevant date for loans in U.S. Dollars to leading European banks for a period
of three months.

      The "10-year Treasury CMT" means the rate determined in accordance with
the following provisions:

(i)  With respect to any  interest  determination  date and the Interest  Period
     that begins immediately thereafter, the 10-year Treasury CMT means the rate
     displayed  on Telerate  Page 7051 under the caption  "...Treasury  Constant
     Maturities...Federal  Reserve  Board Release  H.15...Mondays  Approximately
     3:45 P.M.",  under the column for the  Designated  CMT  Maturity  Index (as
     defined below).

(ii) If such rate is no longer  displayed  on the  relevant  page,  or is not so
     displayed  by 3:00 P.M.,  New York City time,  on the  applicable  interest
     determination  date,  then  the  10-year  Treasury  CMT for  such  interest
     determination  date will be such  treasury  constant  maturity rate for the
     Designated CMT Maturity Index as is published in H.15(519).

(iii)If  such  rate is no  longer  displayed  on the  relevant  page,  or if not
     published  by 3:00 P.M.,  New York City time,  on the  applicable  interest
     determination  date,  then  the  10-year  Treasury  CMT for  such  interest
     determination  date will be such  constant  maturity  treasury rate for the
     Designated CMT Maturity Index (or other United States Treasury rate for the
     Designated CMT Maturity  Index) for the applicable  interest  determination
     date with respect to such  interest  reset date as may then be published by
     either the Board of Governors of the Federal  Reserve  System or the United
     States  Department of the Treasury that the Calculation Agent determines to
     be comparable to the rate formerly  displayed on the Telerate Page 7051 and
     published in H.15(519).

(iv) If such  information  is not provided by 3:00 P.M.,  New York City time, on
     the applicable  interest  determination date, then the 10-year Treasury CMT
     for such interest  determination date will be calculated by the Calculation
     Agent and will be a yield to maturity,  based on the arithmetic mean of the
     secondary market offered rates as of approximately 3:30 P.M., New York City
     time,  on the  interest  determination  date  reported,  according to their
     written  records,   by  three  leading  primary  United  States  government
     securities  dealers in The City of New York (each,  a  "Reference  Dealer")
     selected  by the  Calculation  Agent  (from  five  such  Reference  Dealers
     selected by the Calculation  Agent and  eliminating  the highest  quotation
     (or, in the event of equality, one of the highest) and the lowest quotation
     (or, in the event of equality,  one of the lowest)),  for the most recently
     issued  direct  noncallable  fixed rate  obligations  of the United  States
     ("Treasury  Debentures")  with an original  maturity of  approximately  the
     Designated  CMT Maturity Index and a remaining term to maturity of not less
     than such Designated CMT Maturity Index minus one year.

(v)  If the Calculation Agent is unable to obtain three such Treasury Debentures
     quotations,   the  10-year   Treasury  CMT  for  the  applicable   interest
     determination  date will be calculated by the Calculation Agent and will be
     a yield to maturity  based on the arithmetic  mean of the secondary  market
     offered  rates as of  approximately  3:30 P.M.,  New York City time, on the
     applicable  interest  determination  date of three Reference Dealers in The
     City  of New  York  (from  five  such  Reference  Dealers  selected  by the
     Calculation  Agent and eliminating the highest  quotation (or, in the event
     of equality, one of the highest) and the lowest quotation (or, in the event
     of equality,  one of the lowest)), for Treasury Debentures with an original
     maturity of the number of years that is the next highest to the  Designated
     CMT  Maturity  Index  and a  remaining  term  to  maturity  closest  to the
     Designated CMT Maturity Index and in an amount of at least $100 million.

(vi) If three or four (and not five) of such  Reference  Dealers  are quoting as
     set  forth  above,  then  the  10-year  Treasury  CMT  will be based on the
     arithmetic  mean of the offered rates  obtained and neither the highest nor
     lowest of such quotes will be eliminated;  provided, however, that if fewer
     than three Reference  Dealers selected by the Calculation Agent are quoting
     as set forth above, the 10-year Treasury CMT with respect to the applicable
     interest  determination  date will remain the 10-year  Treasury CMT for the
     immediately  preceding Interest Period. If two Treasury  Debentures with an
     original  maturity  as  described  in the second  preceding  sentence  have
     remaining  terms to maturity  equally close to the  Designated CMT Maturity
     Index,  then the  quotes  for the  Treasury  Debentures  with  the  shorter
     remaining term to maturity will be used.

(vii)"Designated  CMT Maturity  Index" means the original  period to maturity of
     the U.S.  Treasury  securities (10 years) with respect to which the 10-year
     Treasury CMT will be calculated.

(viii)  "Telerate  Page  3750"  means  the  display  designated  on page 3750 on
     MoneyLine  Telerate (or such other page as may replace the 3750 page on the
     service or such other  service as may be nominated by the British  Bankers'
     Association for the purpose of displaying  London  interbank  offered rates
     for U.S. Dollars deposits).

(ix) "Telerate  Page 7051"  means the  display  on  MoneyLine  Telerate  (or any
     successor  service),  on such page (or any other page as may  replace  such
     page on that  service),  for the purpose of  displaying  Treasury  Constant
     Maturities as reported in H.15(519).

(x)  "30-year  Treasury CMT" has the meaning  specified  under the definition of
     10-year Treasury CMT, except that the Designated CMT Maturity Index for the
     30-year Treasury CMT shall be 30 years.

      The 3-month LIBOR Rate, the 10-year Treasury CMT and the 30-year Treasury
CMT shall each be rounded to the nearest hundredth of a percent.

      The Floating Rate with respect to each Floating Rate Period will be
calculated as promptly as practicable by the Calculation Agent according to the
appropriate method described above.

      "Calendar Period" means a period of 180 calendar days.

      If the Company elects to defer interest during a Fixed Rate Period,
interest will continue to accrue at the Fixed Rate until the expiration of the
Fixed Rate Period. Prior to the expiration of such Fixed Rate Period and any
Fixed Rate Period during the Extension Period, the Company will have the option
to remarket the Series B Debentures for a new Fixed Rate Period (to take effect
upon expiration of such Fixed Rate Period). If the Company does not remarket the
Series B Debentures, the Floating Rate during the Extension Period shall be
determined as provided herein, but shall not be less than the Fixed Rate for the
Fixed Rate Period just ended. If the Company elects to defer interest during a
Floating Rate Period, interest will continue to accrue at the applicable
Floating Rate, reset quarterly, subject to the right of the Company to remarket
the Series B Debentures prior to any Interest Payment Date in order to establish
a new Fixed Rate for a new Fixed Rate Period in accordance with the Remarketing
Procedures.

      SECTION 203.      Interest Periods

      In accordance with Section 202 and the Remarketing Procedures, the Company
may, prior to the expiration of the Initial Fixed Rate Period or any subsequent
Fixed Rate Period or prior to any Interest Payment Date during a time in which
the Series B Debentures are redeemable in any Fixed Rate Period or an Interest
Payment Date with respect to a Floating Rate Period, elect to remarket the
Series B Debentures to establish a new Fixed Rate for a new Fixed Rate Period. A
Fixed Rate Period must be for a duration of at least six months, may not extend
beyond the Stated Maturity of the Series B Debentures and may not end on a day
other than a day immediately preceding an Interest Payment Date. If a new Fixed
Rate for a new Fixed Rate Period is set in a Remarketing, a new Fixed Rate
Period shall commence following the expiration of the then current Fixed Rate
Period or Interest Period within the current Floating Rate Period, as the case
may be. If a new Fixed Rate for a new Fixed Rate Period is not set, for any
reason, a Floating Rate Period, and the Floating Rate, reset quarterly, shall be
in effect until the Company remarkets the Series B Debentures and sets a new
Fixed Rate for a new Fixed Rate Period in accordance with the Remarketing
Procedures.

                                    ARTICLE 3
                             Remarketing Procedures

      Article 10 of the Trust Agreement sets forth the Remarketing Procedures to
determine the applicable Fixed Rate for the Preferred Securities. If the Trust
is terminated and the Series B Debentures are distributed to the holders of the
Preferred Securities subject to Section 103 herein, the below described
Remarketing Procedures will be applicable to the Series B Debentures.

      SECTION 301.      Election to Remarket

      If the Company elects to conduct a Remarketing, the Company, not less than
20 nor more than 35 Business Days prior to the related Election Date, is
required to give the written notice of Remarketing of the Series B Debentures to
the Clearing Agency, the Indenture Trustee, the Calculation Agent and the
Remarketing Agent. If the Series B Debentures are not issued in global, fully
registered form, such notice shall be delivered to the holders of the Series B
Debentures instead of the Clearing Agency. Such notice will describe the
Remarketing and will indicate the length of the proposed new Fixed Rate Period,
the proposed Remarketing Date and any redemption provisions that apply during
such new Fixed Rate Period. At any time prior to the Election Date, the Company
may elect to terminate a Remarketing by giving the Clearing Agency (or the
holders as applicable), the Remarketing Agent, the Indenture Trustee and the
Calculation Agent written notice of such termination.

      SECTION 302.      Notice of Election

      Not later than 4:00 p.m., New York City time, on an Election Date, each
holder of Series B Debentures may give a written notice to the Indenture Trustee
of its election ("Notice of Election") (i) to retain and not to have all or any
portion of the Series B Debentures owned by it remarketed in the Remarketing, or
(ii) to tender all or any portion of such Series B Debentures for purchase in
the Remarketing (such portion, in either case, is required to be in the
Liquidation Amount of $1,000 or any integral multiple thereof). Any Notice of
Election given to the Indenture Trustee will be irrevocable and may not be
conditioned upon the level at which the Fixed Rate is established in the
Remarketing. Promptly after 4:30 p.m., New York City time, on such Election
Date, the Indenture Trustee, based on the Notices of Election received by it
through the Clearing Agency prior to such time, will notify the Company and the
Remarketing Agent of the number of Series B Debentures to be retained by holders
of Series B Debentures and the number of Series B Debentures tendered for
purchase in the Remarketing.

      If any holder of Series B Debentures gives a Notice of Election to tender
Series B Debentures as described above, the Series B Debentures so subject to
such Notice of Election will be deemed tendered for purchase in the Remarketing,
notwithstanding any failure by such holder to deliver or properly deliver such
Series B Debentures to the Remarketing Agent for purchase. If any holder of
Series B Debentures fails timely to deliver a Notice of Election, as described
above, such Series B Debentures will be deemed tendered for purchase in such
Remarketing, notwithstanding such failure or the failure by such holder to
deliver or properly deliver such Series B Debentures to the Remarketing Agent
for purchase.

      The right of each holder of Series B Debentures to have Series B
Debentures tendered for purchase in the Remarketing shall be limited to the
extent that (i) the Remarketing Agent conducts a Remarketing pursuant to the
terms of the Remarketing Agreement; (ii) Series B Debentures tendered have not
been called for redemption; (iii) the Remarketing Agent is able to find a
purchaser or purchasers for tendered Series B Debentures at a Fixed Rate; and
(iv) such purchaser or purchasers deliver the purchase price therefor to the
Remarketing Agent.

      Any holder of Series B Debentures that desires to continue to retain a
number of Series B Debentures, but only if the Fixed Rate is not less than a
specified rate per annum, shall submit a Notice of Election to tender such
Series B Debentures and separately notify the Remarketing Agent of its interest
at the telephone number set forth in the notice of Remarketing. If such holder
so notifies the Remarketing Agent, the Remarketing Agent will give priority to
such holder's purchase of such number of Series B Debentures in the Remarketing,
providing that the Fixed Rate is not less than such specified rate.

      SECTION 303.      Determination of Interest Rate

      If holders submit Notices of Election to retain all of the Series B
Debentures then outstanding, the Fixed Rate will be the rate determined by the
Remarketing Agent, in its sole discretion, as the rate that would have been
established had a Remarketing been held on the related Remarketing Date.

      On any Remarketing Date on which the remarketing is to be conducted, the
Remarketing Agent will use commercially reasonable efforts to remarket, at a
price equal to 100% of the Liquidation Amount thereof, Series B Debentures
tendered or deemed tendered for purchase. Except as provided in the previous
paragraph of this Section 303, if, as a result of such efforts, on any
Remarketing Date, the Remarketing Agent has determined that it will be able to
remarket all Series B Debentures tendered or deemed tendered for purchase in the
Remarketing at a Fixed Rate and at a price of $1,000 per Series B Debenture,
prior to 4:00 p.m., New York City time, on such Remarketing Date, the
Remarketing Agent will determine the Fixed Rate, which will be the rate per
annum (rounded to the nearest one-thousandth (0.001) of one percent per annum)
which the Remarketing Agent determines, in its sole judgment, to be the lowest
Fixed Rate per annum, if any, that will enable it to remarket all Series B
Debentures tendered or deemed tendered for Remarketing at a price of $1,000 per
Series B Debenture.

      If the Remarketing Agent is unable to remarket by 4:00 p.m., New York City
time on the third Business Day prior to the Remarketing Settlement Date, all
Series B Debentures tendered or deemed tendered for a purchase at a price of
$1,000 per Series B Debenture, the Interest Rate for the next Interest Period
shall be the Floating Rate and the new Interest Period shall be a Floating Rate
Period. In such case, no Series B Debentures will be sold in the Remarketing and
each holder will continue to hold its Series B Debentures at the Floating Rate
during such Floating Rate Period.

      All Series B Debentures tendered or deemed tendered in the Remarketing
will be automatically delivered to the account of the Remarketing Agent through
the facilities of the Clearing Agency against payment of the purchase price
therefor on the Remarketing Settlement Date. The Remarketing Agent will make
payment to the Clearing Agency Participant of each tendering holder of Series B
Debentures in the Remarketing through the facilities of the Clearing Agency by
the close of business on the Remarketing Settlement Date.

      In accordance with the Clearing Agency's normal procedures, on the
Remarketing Settlement Date, the transaction described above with respect to
each Series B Debenture tendered for purchase and sold in the Remarketing, will
be executed through the Clearing Agency Participants, will be debited and
credited and such Series B Debentures delivered by book entry as necessary to
effect purchases and sales of such Series B Debentures. The Clearing Agency is
expected to make payment in accordance with its normal procedures.

      If any holder selling Series B Debentures in the Remarketing fails to
deliver such Series B Debentures, the Clearing Agency Participant of such
selling holder and of any other person that was to have purchased Series B
Debentures in the Remarketing may deliver to any such other person a number of
Series B Debentures that is less than the number of Series B Debentures that
otherwise was to be purchased by such person. In such event, the number of
Series B Debentures to be so delivered will be determined by such Clearing
Agency Participant and delivery of such lesser number of Series B Debentures
will constitute good delivery.

      The Remarketing Agent is not obligated to purchase any Series B Debentures
that would otherwise remain unsold in a Remarketing. Neither the Indenture
Trustee, the Company nor the Remarketing Agent shall be obligated in any case to
provide funds to make payment upon tender of Series B Debentures for
Remarketing.

      SECTION 304.      Remarketing Agent

      Prior to the issuance of the Series B Debentures, the Company and the
Trust will enter into the Remarketing Agreement with the Remarketing Agent,
providing, among other things, that the Remarketing Agent will follow the
Remarketing Procedures for the purposes of determining the applicable Fixed
Rate. The Company will pay the Remarketing Agent compensation for its services
under the Remarketing Agreement.

                                    ARTICLE 4
                            Miscellaneous Provisions

      SECTION 401.      Recitals by Company

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

      SECTION 402.      Ratification and Incorporation of Original Indenture

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

      SECTION 403.      Trust Costs and Expenses

      The Company, as borrower, has agreed to pay all debts and obligations
(other than with respect to the Trust Securities) and all costs and expenses of
the Trust (including, but not limited to, all costs and expenses relating to the
organization of the Trust, the fees and expenses of the Trustees and all costs
and expenses relating to the operation of the Trust (other than with respect to
the Trust Securities)) and to pay any and all taxes, duties, assessments or
other governmental charges of whatever nature (other than United States federal
withholding taxes) imposed by the United States or any other taxing authority,
so that the net amounts received and retained by the Trust after paying such
debts, obligations, costs, expenses, taxes, duties, assessments or other
governmental charges will be equal to the amounts the Trust would have received
had no such debts, obligations, costs, expenses, taxes, duties, assessments or
other governmental charges been incurred by or imposed on the Trust. The
foregoing obligations of the Company are for the benefit of, and shall be
enforceable by, any person to whom any such debts, obligations, costs, expenses,
taxes, duties, assessments or other governmental charges are owed (each a
"Creditor") whether or not such Creditor has received notice thereof. Any such
Creditor may enforce such obligations of the Company directly against the
Company, and the Company irrevocably waives any right or remedy to require that
such Creditor take any action against the Trust or any other person before
proceeding against the Company. The Company shall execute such additional
agreements as may be necessary or desirable to give full effect to the
foregoing.



      SECTION 404.      Executed in Counterparts

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

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

                     SERIES B JUNIOR SUBORDINATED DEBENTURE
                               DUE OCTOBER 1, 2043

Principal Amount:       $________________
Regular Record Date:    The opening of business on the Business Day
                        immediately preceding the relevant Interest Payment
                        Date
Original Issue Date:    October 1, 2003
Stated Maturity:        October 1, 2043
Interest Rate:          Determined by procedures set forth in the Indenture

Authorized Denomination:$1,000

      Southwestern Electric Power Company, a Delaware corporation (the
"Company", which term includes any successor corporation under the Indenture
referred to on the reverse hereof), for value received, hereby promises to pay
to ________________, or registered assigns, the principal sum of
_______________________($__________) on the Stated Maturity shown above (or upon
earlier redemption), and to pay interest thereon from the Original Issue Date
shown above, or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, on each Interest Payment Date commencing on the
Interest Payment Date next succeeding the Original Issue Date shown above and on
the Stated Maturity (or upon earlier redemption) at the prevailing Interest Rate
until the principal hereof is paid or made available for payment and on any
overdue principal and on any overdue installment of interest. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
(other than an Interest Payment Date that is the Stated Maturity or on a
Redemption Date) will, as provided in such Indenture, be paid to the Person in
whose name this Debenture (the "Debenture") is registered on the Regular Record
Date as specified above next preceding such Interest Payment Date, provided that
any interest payable at Stated Maturity or on any Redemption Date will be paid
to the Person to whom principal is payable. Except as otherwise provided in the
Indenture, any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Debenture is registered at the
close of business on a Special Record Date for the payment of such defaulted
interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Debentures of this series not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange, if any, on which the Debentures of
this series shall be listed, and upon such notice as may be required by any such
exchange, all as more fully provided in the Indenture.

      Payments of interest on this Debenture in respect of a Floating Rate
Period (or a portion thereof) will be computed by multiplying the per annum
Interest Rate in effect for such Floating Rate Period by a fraction, the
numerator of which will be the actual number of days in such Floating Rate
Period (or portion thereof) (determined by including the first day thereof and
excluding the last thereof) and the denominator of which will be 360, and
multiplying the rate so obtained by the principal amount hereof. The amount of
interest on this Debenture payable on each Interest Payment Date in respect of a
Fixed Rate Period will be computed on the basis of a 360-day year consisting of
twelve 30-day months.

      The Company has the right to defer payments of interest on this Debenture
by extending the interest payment period from time to time on this Debenture (an
"Extension Period").

      If the Company decides to defer interest payments on this Debenture, the
Extension Period shall not exceed five consecutive years. An Extension Period
shall not extend beyond the Stated Maturity of this Debenture. Prior to the
termination of any Extension Period, the Company may further defer payments of
interest provided that the Extension Period, together with all such previous and
further extensions thereof, may not exceed five consecutive years. Upon the
termination of any Extension Period and the payment of all amounts then due, the
Company may select a new Extension Period, subject to the above requirements.
There could be multiple Extension Periods of varying lengths throughout the term
of this Debenture.

      During an Extension Period, unpaid interest (together with interest
thereon) will compound on each Interest Payment Date at the prevailing Interest
Rate ("Deferred Interest"). Upon the termination of each Extension Period, which
shall be an Interest Payment Date, the Company shall pay all Deferred Interest
on the next succeeding Interest Payment Date to the Person in whose name this
Debenture is registered at the close of business on the Regular Record Date for
such Interest Payment Date, provided that any Deferred Interest payable at
Stated Maturity or on any Redemption Date will be paid to the Person to whom
principal is payable.

      If the Company shall have given notice of its election to select any
Extension Period, the Company shall not (1) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of its capital stock, (2) make any payment of principal of
or interest or premium, if any, on or repay, repurchase or redeem any of its
debt securities of ours that rank equally with, or junior to, the Series B
Debentures, or (3) make any guarantee payments with respect to any guarantee
issued by the Company if such guarantee ranks equally with, or junior to, the
Series B Debentures, other than, in each case, repurchases, redemptions or other
acquisitions of shares of its:

- -     capital stock in connection with any employment contract, benefit plan or
      other similar arrangement with or for the benefit of any one or more
      employees, officers, directors or consultants or in connection with a
      dividend reinvestment or shareholder stock purchase plan;

- -     as a result of an exchange or conversion of any class or series of the
      Company's capital stock, or any capital stock of a subsidiary of the
      Company, for any class or series of the Company's capital stock or of any
      class or series of the Company's then outstanding indebtedness for any
      class or series of the Company's capital stock;

- -     the purchase of fractional interests in shares of the Company's capital
      stock pursuant to the conversion or exchange provisions of the capital
      stock or the security being converted or exchanged;

- -     payments  under any  Guarantee  executed  and  delivered  by the Company
      concurrently with the issuance of any Preferred Securities;

- -     any declaration of a dividend in the form of capital stock in connection
      with any shareholders' rights plan, or the issuance of rights to capital
      stock under any shareholders' rights plan, or the redemption or repurchase
      of rights pursuant to any such plan; or

- -     any dividend in the form of stock, warrants, options or other rights where
      the dividend stock or the stock issuable upon exercise of the warrants,
      options or other rights is the same stock as that on which the dividend is
      being paid or ranks on a parity with or junior to the stock,

if at such time

- -     the Company has actual knowledge of any event that (a) with the giving of
      notice or the lapse of time, or both, would constitute an Event of Default
      under the Indenture, and (b) the Company has not taken reasonable steps to
      cure the same;

- -     the Company is in default with respect to payment of any obligations under
      any Guarantee executed and delivered concurrently with the issuance of any
      Preferred Securities; or

- -     an extension period is continuing.

      The Company shall give the Holder of this Debenture, the Trustee, the
Remarketing Agent and the Calculation Agent notice of its selection or extension
of an Extension Period at least one Business Day prior to the earlier of (i) the
Regular Record Date relating to the Interest Payment Date on which the Extension
Period is to commence or relating to the Interest Payment Date on which an
Extension Period that is being extended would otherwise terminate or (ii) the
date the Company or Trust is required to give notice to any applicable
self-regulatory organization of the record date or the date distributions are
payable.

      The Company also shall be obligated to pay when due and without extension
all additional amounts as may be required so that the net amount received and
retained by the Holder of this Debenture (if the Holder is a Trust) after paying
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States or any other taxing
authority will not be less than the amounts such Holder would have received had
no such taxes, duties, assessments, or other governmental charges been imposed.

      Payment of the principal of and interest due at the Stated Maturity or
earlier redemption of the Series B Debentures shall be made upon surrender of
the Series B Debentures at the Corporate Trust Office of the Trustee, in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts. Payment of interest
(including interest on an Interest Payment Date) 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 16 days prior to the date for payment by the Person
entitled thereto.

      The indebtedness evidenced by this Debenture is, to the extent provided in
the Indenture, subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness (as defined in the Indenture), and this
Debenture is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this Debenture, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided, and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance hereof, waives
all notice of the acceptance of the subordination provisions contained herein
and in the Indenture by each holder of Senior Indebtedness, whether now
outstanding or hereafter incurred, and waives reliance by each such holder upon
said provisions.

      Each Holder hereof, by his acceptance hereof, agrees to treat this
Debenture as indebtedness for all United States tax purposes.

      REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS DEBENTURE SET
FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES
HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.

      Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Debenture shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.



      IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                          CERTIFICATE OF AUTHENTICATION

 This is one of the Debentures referred to in the within-mentioned Indenture.

                                          THE BANK OF NEW YORK,
                                          as Trustee


                                          By:
                                               -------------------------------
                                                Authorized Officer



                          (Reverse Side of Debenture)

      This Debenture is one of a duly authorized issue of Junior Subordinated
Debentures of the Company (the "Debentures"), issued and issuable in one or more
series under a Subordinated Indenture, dated as of September 1, 2003 as
supplemented by the First Supplemental Indenture (the "First Supplemental
Indenture") dated as of October 1, 2003 (collectively, the "Indenture") between
the Company and The Bank of New York, as trustee (the "Trustee," which term
includes any successor trustee under the Indenture), to which Indenture and all
indentures incidental thereto reference is hereby made for a statement of the
respective rights, limitation of rights, duties and immunities thereunder of the
Company, the Trustee and the Holders of the Debentures issued thereunder and of
the terms upon which said Debentures are, and are to be, authenticated and
delivered. This Debenture is one of the series designated on the face hereof as
Series B Junior Subordinated Debentures due October 1, 2043 (the "Series B
Debentures") in the aggregate principal amount of up to $113,403,000.
Capitalized terms used herein for which no definition is provided herein shall
have the meanings set forth in the Indenture.

      While the Preferred Securities are outstanding, (i) the Interest Rate,
Interest Periods, Interest Payment Dates and associated terms and redemption
provisions with respect to the Fixed Rate Periods relating to this Debenture
shall be the same as the Distribution Rate, Distribution Periods, Distribution
Payment Dates and associated terms and redemption provisions with respect to
Fixed Rate Periods relating to the Preferred Securities, established in Article
4 of the Trust Agreement and (ii) the Remarketing Procedures relating to this
Debenture shall be the same as those procedures relating to the Preferred
Securities, established in Article 10 of the Trust Agreement.

      If the Trust is terminated and this Debenture is distributed to holders of
Preferred Securities, subject to Section 103 of the First Supplemental
Indenture, the terms and procedures relating to the Preferred Securities as
established in Articles 4 and 10 of the Trust Agreement shall be directly
applicable to this Debenture as described in Articles 2 and 3 of the First
Supplemental Indenture.

      The Company shall have the right, subject to the terms and conditions of
the Indenture, to redeem this Debenture on the last Interest Payment Date
relating to the Initial Fixed Rate Period, on such dates with respect to any
other Fixed Rate Period as the Company and the Trust may determine prior to the
Remarketing establishing such Fixed Rate Period or on any Interest Payment Date
relating to a Floating Rate Period at the option of the Company, without premium
or penalty, in whole, but not in part, at a Redemption Price equal to 100% of
the principal amount to be redeemed plus accrued but unpaid interest to the
Redemption Date. Upon the occurrence of a Special Event (as defined below) at
any time, the Company may, within 90 days following the occurrence thereof and
subject to the terms and conditions of the Indenture, redeem this Debenture
without premium or penalty, in whole, but not in part, at a Redemption Price
equal to 100% of the principal amount thereof plus accrued but unpaid interest
to the Redemption Date. A Special Event may be a Tax Event or an Investment
Company Event. "Tax Event" means that the Company and, if applicable, the
Administrative Trustees shall have received an opinion from independent tax
counsel experienced in such matters (which may be counsel to the Company) to the
effect that, as a result of (a) any amendment to, or change (including any
announced proposed change) in, the laws (or any regulations thereunder) of the
United States or any political subdivision or taxing authority thereof or
therein or (b) any amendment to, or change in, an interpretation or application
of such laws or regulations, there is more than an insubstantial risk that (i)
the Trust would be subject to United States federal income tax with respect to
income accrued or received on the Series B Debentures; (ii) interest payable on
the Series B Debentures would not be deductible, in whole or in part, by the
Company for United States federal income tax purposes; or (iii) the Trust would
be subject to more than a de minimis amount of other taxes, duties or other
governmental charges, which change or amendment becomes effective on or after
the date of issuance by the Trust of the Preferred Securities.

      "Investment Company Event" means the receipt by the Administrative
Trustees of an Opinion of Counsel to the Company experienced in these matters to
the effect that, as a result of the occurrence of a change in law or regulation
or a written change--including any announced prospective change--in
interpretation or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority, there is more than an
insubstantial risk that the Trust is or will be considered an "investment
company" that is required to be registered under the 1940 Act, which change or
prospective change becomes effective or would become effective, as the case may
be, on or after the date of the issuance by the Trust of the Preferred
Securities.

      If an Event of Default with respect to the Debentures of this series shall
occur and be continuing, the principal of the Debentures of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of not less than a majority in principal amount of the
Debentures at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting the Holders of specified percentages in
principal amount of the Debentures of each series at the time Outstanding, on
behalf of the Holders of all Debentures of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Debenture shall be conclusive and binding upon such Holder and
upon all future Holders of this Debenture and of any Debenture issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Debenture.

      No reference herein to the Indenture and no provision of this Debenture or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this
Debenture at the times, place and rate, and in the coin or currency, herein
prescribed.

      As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Debenture is registrable in the Security
Register, upon surrender of this Debenture for registration of transfer at the
office or agency of the Company for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar and duly executed by, the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new
Debentures of this series, of authorized denominations and of like tenor and for
the same aggregate principal amount, will be issued to the designated transferee
or transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

      Prior to due presentment of this Debenture for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Debenture is registered as the owner hereof for
all purposes, whether or not this Debenture be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

      The Debentures of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Debentures of this series are exchangeable for a like aggregate principal amount
of Debentures of this series of a different authorized denomination, as
requested by the Holder surrendering the same upon surrender of the Debenture or
Debentures to be exchanged at the office or agency of the Company.

      This Debenture shall be governed by, and construed in accordance with, the
internal laws of the State of New York.
