         AMERICAN ELECTRIC POWER COMPANY, INC., a corporation duly organized and
existing  under the laws of the  State of New York  (herein  referred  to as the
"Company",  which term  includes any successor  corporation  under the Indenture

______________  or  registered  assigns,  the  principal  sum of  ______________
Dollars on  __________,  ____,  and to pay interest on said  principal  sum from
__________,  ____ or from the most recent interest payment date (each such date,
an "Interest  Payment  Date") to which  interest has been paid or duly  provided

applicable  law) on any  overdue  installment  of  interest at the same rate per
annum during such overdue  period.  Interest shall be computed on the basis of a
360-day  year of  twelve  30-day  months.  In the  event  that any date on which
interest is payable on this  Debenture  is not a business  day,  then payment of
interest payable on such date will be made on the next succeeding day which is a

installment  so  payable,  and  punctually  paid or duly  provided  for,  on any

or maturity  shall be payable to the person to whom the  principal is paid.  Any
such  interest  installment  not  punctually  paid or duly  provided  for  shall
forthwith  cease to be payable to the registered  holders on such regular record
date, and may be paid to the person in whose name this Debenture (or one or more
Predecessor  Debentures)  is  registered  at the close of  business on a special
record  date to be  fixed  by the  Trustee  for the  payment  of such  defaulted

of Debentures not less than 10 days prior to such special record date, or may be
paid  at any  time  in  any  other  lawful  manner  not  inconsistent  with  the
requirements  of any securities  exchange on which the Debentures may be listed,

provided  in the  Indenture.  The  principal  of (and  premium,  if any) and the
interest  on this  Debenture  shall be  payable  at the  office or agency of the
Company  maintained  for that  purpose,  in any coin or  currency  of the United

public and private  debts;  PROVIDED,  HOWEVER,  that payment of interest may be
made at the option of the Company by check  mailed to the  registered  holder at
such address as shall appear in the Debenture Register.

         Payment of the  principal  of,  premium,  if any,  and interest on this
Debenture is, to the extent provided in the Indenture,  subordinated and subject
in right of payment to the prior payment in full of all Senior Indebtedness,  as

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 or her behalf to take such action as
may be necessary or appropriate  to acknowledge or effectuate the  subordination
so provided and (c) appoints the Trustee his or her attorney-in-fact for any and
all such purposes.  Each Holder hereof, by his or her acceptance hereof,  hereby
waives all notice of the acceptance of the  subordination  provisions  contained

Authorized Signatory

                         (FORM OF REVERSE OF DEBENTURE)

         This Debenture is one of a duly authorized  series of Debentures of the
Company (herein  sometimes  referred to as the  "Debentures"),  specified in the
Indenture,  all issued or to be issued in one or more series  under and pursuant
to an Indenture dated as of __________, ____ duly executed and delivered between
the Company and The Bank of New York, a national banking  association  organized
and existing under the laws of the United States, as Trustee (herein referred to
as the "Trustee"),  as supplemented by the First Supplemental Indenture dated as
of  __________,  ____ between the Company and the Trustee (said  Indenture as so
supplemented  being  hereinafter  referred  to as  the  "Indenture"),  to  which
Indenture and all indentures supplemental thereto reference is

<PAGE>

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  Debentures.  By the terms of the Indenture,  the Debentures 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 series of  Debentures  is
limited in aggregate  principal  amount as specified in said First  Supplemental
Indenture.

         Subject to the terms of Article  Three of the  Indenture,  the  Company
shall have the right to redeem  this  Debenture  at the  option of the  Company,
without  premium  or  penalty,  in  whole  or in  part at any  time on or  after
__________, ____ (an "Optional Redemption"), at a redemption price equal to 100%
of the principal amount plus any accrued but unpaid interest to the date of such
redemption (the "Optional  Redemption  Price").  Any redemption pursuant to this
paragraph  will be made upon not less than 30 nor more than 60 days' notice,  at
the Optional  Redemption Price. If the Debentures are only partially redeemed by
the Company pursuant to an Optional Redemption,  the Debentures will be redeemed
pro rata or by lot or by any other method utilized by the Trustee; provided that
if at the  time  of  redemption,  the  Debentures  are  registered  as a  Global
Debenture,  the Depository  shall determine by lot the principal  amount of such
Debentures held by each Debentureholder to be redeemed.

         In the  event of  redemption  of this  Debenture  in part  only,  a new
Debenture or Debentures of this series for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

         In case an Event of Default,  as defined in the  Indenture,  shall have
occurred  and be  continuing,  the  principal  of all of the  Debentures  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  Debenture  upon  compliance  by the Company  with
certain conditions set forth therein.

         The  Indenture  contains  provisions  permitting  the  Company  and the
Trustee,  with the  consent  of the  Holders  of not  less  than a  majority  in
aggregate principal amount of the Debentures 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  Debentures;  provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any  Debentures 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,  without the consent of the holder
of each  Debenture  so  affected  or (ii)  reduce the  aforesaid  percentage  of
Debentures,   the  holders  of  which  are  required  to  consent  to  any  such
supplemental  indenture,  without the  consent of the holders of each  Debenture
then outstanding and affected  thereby.  The Indenture also contains  provisions
permitting  the  Holders  of a majority  in  aggregate  principal  amount of the
Debentures of all series at the time outstanding  affected thereby, on behalf of
the Holders of the  Debentures 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

<PAGE>

default in the payment of the  principal  of or premium,  if any, or interest on
any of the  Debentures  of such  series.  Any  such  consent  or  waiver  by the
registered  Holder  of  this  Debenture  (unless  revoked  as  provided  in  the
Indenture)  shall be conclusive and binding upon such Holder and upon all future
Holders and owners of this  Debenture  and of any  Debenture  issued in exchange
herefor or in place hereof  (whether by  registration of transfer or otherwise),
irrespective  of whether or not any  notation of such  consent or waiver is made
upon this 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 premium, if any, and
interest  on this  Debenture  at the time and  place  and at the rate and in the
money herein prescribed.

         The  Company  shall  have the right at any time  during the term of the
Debentures,  from time to time to extend  the  interest  payment  period of such
Debentures for up to 20 consecutive  quarters (the  "Extended  Interest  Payment
Period"),  at the end of which period the Company  shall pay all  interest  then
accrued and unpaid (together with interest thereon  compounded  quarterly at the
rate specified for the Debentures to the extent that payment of such interest is
enforceable under applicable law);  provided that, during such Extended Interest
Payment  Period  the  Company  shall  not  declare  or pay any  dividend  on, or
purchase,  acquire or make a  liquidation  payment  with  respect to, any of its
capital stock, or make any guarantee payments with respect thereto. Prior to the
termination  of any such  Extended  Interest  Payment  Period,  the  Company may
further extend such Extended Interest Payment Period,  provided that such Period
together with all such previous and further  extensions thereof shall not exceed
20 consecutive quarters or extend beyond the maturity of the Debentures.  At the
termination of any such Extended Interest Payment Period and upon the payment of
all accrued and unpaid interest and any additional amounts then due, the Company
may select a new Extended Interest Payment Period.

         As provided in the Indenture and subject to certain limitations therein
set forth, this Debenture is transferable by the registered holder hereof on the
Debenture  Register  of the  Company,  upon  surrender  of  this  Debenture  for
registration of transfer at the office or agency of 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
Debentures  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.

         Prior  to  due  presentment  for   registration  of  transfer  of  this
Debenture,  the  Company,  the  Trustee,  any  paying  agent  and any  Debenture
Registrar may deem and treat the registered  Holder hereof as the absolute owner
hereof (whether or not this Debenture shall be overdue and  notwithstanding  any
notice of  ownership or writing  hereon made by anyone other than the  Debenture
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
Debenture Registrar shall be affected by any notice to the contrary.

<PAGE>

interest on this  Debenture,  or for any claim based  hereon,  or  otherwise  in
respect  hereof,  or  based  on or in  respect  of the  Indenture,  against  any

virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise,  all such liability being, by the acceptance
hereof  and as part of the  consideration  for the  issuance  hereof,  expressly
waived and released.

                                 TRUST AGREEMENT

     THIS TRUST AGREEMENT, dated as of February 19, 2002, among (i) AMERICAN
ELECTRIC POWER COMPANY, INC., a New York corporation (the "Depositor"), (ii)
WILMINGTON TRUST COMPANY, a Delaware banking corporation, as Delaware Trustee
(the "Delaware Trustee"), and Jeffrey D. Cross and Stephan T. Haynes, each an
individual, as administrative trustees (the "Administrative Trustees" and
collectively with the Delaware Trustee, the "Trustees"). The Depositor and the
Trustees hereby agree as follows:

1. The trust created hereby (the "Trust") shall be known as AEP CAPITAL TRUST I,
in which name the Trustees, or the Depositor to the extent provided herein, may
conduct the business of the trust, make and execute contracts, and sue and be
sued.

2. The Depositor hereby assigns, transfers, conveys and sets over to the
Administrative Trustees the sum of $10.00. The Administrative Trustees hereby
acknowledge receipt of such amount in trust from the Depositor, which amount
shall constitute the initial trust estate. The Trustees hereby declare that they
will hold the trust estate in trust for the Depositor.

3. It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 Del. C. Section 3801 et seq. (the "Business Trust Act"), and that this
document constitutes the governing instrument of the Trust.

4. The Trustees are hereby authorized and directed to execute and file a
certificate of trust with the Delaware Secretary of State in accordance with the
provisions of the Business Trust Act.

5. The Depositor and the Trustees will enter into an amended and restated Trust
Agreement, satisfactory to each such party and substantially in the form
included as an exhibit to the 1933 Act Registration Statement (as defined
below), to provide for the contemplated operation of the Trust created hereby
and the issuance of the Preferred Securities and Common Securities referred to
therein (collectively, the "Trust Securities"). Prior to the execution and
delivery of such amended and restated Trust Agreement, the Trustees shall not
have any duty or obligation hereunder or with respect to the trust estate,
except as otherwise required by applicable law or as may be necessary to obtain
prior to such execution and delivery of any licenses, consents or approvals
required by applicable law or otherwise. However, notwithstanding the foregoing,
all Trustees may take all actions deemed proper as are necessary to effect the
transactions contemplated herein.

6. The Depositor and the Trustees hereby authorize and direct the Depositor, as
the agent of the Trust, (i) to file with the Securities and Exchange Commission
(the "Commission") and execute, on behalf of the Trust, the Registration
Statement on Form S-3 (the 1933 Act Registration Statement), including any
pre-effective or post-effective amendments to the 1933

<PAGE>

Act Registration Statement, relating to the registration under the Securities
Act of 1933, as amended, of the Preferred Securities of the Trust; (ii) to file
with the New York Stock Exchange, The Nasdaq National Market or the
Over-the-Counter Bulletin Board (each, an Exchange) and execute on behalf of the
Trust one or more listing applications and all other applications, statements,
certificates, agreements and other instruments as shall be necessary or
desirable to cause the Preferred Securities to be listed on any of the
Exchanges; and (iii) to file and execute on behalf of the Trust such
applications, reports, surety bonds, irrevocable consents, appointments of
attorney for service of process and other papers and documents as shall be
necessary or desirable to register the Preferred Securities under the securities
or blue sky laws of such jurisdictions as the Depositor, on behalf of the Trust,
may deem necessary or desirable. In the event that any filing referred to in
clauses (i), (ii) and (iii) above is required by the rules and regulations of
the Commission, an Exchange or state securities or blue sky laws, to be executed
on behalf of the Trust by one or more of the Trustees, Jeffrey D. Cross and
Stephan T. Haynes, in their capacities as Administrative Trustees of the Trust,
are hereby authorized and, to the extent so required, directed to join in any
such filing and to execute on behalf of the Trust any and all of the foregoing,
it being understood that Wilmington Trust Company in its capacity as a Trustee
of the Trust shall not be required to join in any such filing or execute on
behalf of the Trust any such document unless required by the rules and
regulations of the Commission, the Exchange or state securities or blue sky
laws. In connection with the filings referred to above, the Depositor and
Trustees, solely as Trustees and not in their individual capacities, hereby
constitutes and appoints Jeffrey D. Cross and Stephan T. Haynes, and each of
them, as its true and lawful attorneys-in-fact and agents, with full power of
substitution and resubstitution, for the Depositor or such Trustee or in the
Depositor's or such Trustees' name, place and stead, in any and all capacities,
to sign any and all amendments (including post-effective amendments) to the 1933
Act Registration Statement and the 1934 Act Registration Statement and to file
the same, with all exhibits thereto, and other documents in connection
therewith, with the Commission, the Exchange and administrators of the state
securities or blue sky laws, granting unto said attorneys-in-fact and agents
full power and authority to do and perform each and every act and thing
requisite and necessary to be done in connection therewith, as fully to all
intents and purposes as the Depositor or such Trustee might or could do in
person, hereby ratifying and confirming all that said attorneys-in-fact and
agents or any of them, or their respective substitute or substitutes, shall do
or cause to be done by virtue hereof.

7. (a) The Trustees and their officers, directors, agents, shareholders,
members, partners, employees, representatives, nominees, custodians and servants
(collectively, the "Fiduciary Indemnified Persons") shall not be liable,
responsible or accountable in damages or otherwise to the Trust, the Depositor,
the Trustees or any holder of the Trust Securities (the Trust, the Depositor and
any holder of the Trust Securities being a "Covered Person") for any loss,
damage or claim incurred by reason of any act or omission performed or omitted
by the Fiduciary Indemnified Persons in good faith on behalf of the Trust and in
a manner the Fiduciary Indemnified Persons reasonably believed to be within the
scope of authority conferred on the Fiduciary Indemnified Persons by this Trust
Agreement or by law, except that the Fiduciary Indemnified Persons shall be
liable for any such loss, damage or claim incurred by reason of the Fiduciary
Indemnified Person's gross negligence or willful misconduct with respect to such
acts or omissions.

<PAGE>

     (b) The Fiduciary Indemnified Persons shall be fully protected in relying
in good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any person as to matters the
Fiduciary Indemnified Persons reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which distributions to holders of Trust Securities might properly be paid.

     (c) The Depositor agrees, to the fullest extent permitted by applicable
law, (i) to indemnify and hold harmless each Fiduciary Indemnified Person from
and against any loss, damage, liability, tax, penalty, expense or claim of any
kind or nature whatsoever incurred by the Fiduciary Indemnified Persons by
reason of the creation, operation or termination of the Trust in a manner the
Fiduciary Indemnified Persons reasonably believed to be within the scope of
authority conferred on the Fiduciary Indemnified Persons by this Trust Agreement
of Trust, except that no Fiduciary Indemnified Persons shall be entitled to be
indemnified in respect of any loss, damage or claim incurred by the Fiduciary
Indemnified Persons by reason of gross negligence or willful misconduct with
respect to such acts or omissions, and (ii) to advance expenses (including legal
fees) incurred by a Fiduciary Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, prior to the final
disposition of such claim, demand, action, suit or proceeding, upon receipt by
the Trust of an undertaking by or on behalf of such Fiduciary Indemnified
Persons to repay such amount if it shall be determined that such Fiduciary
Indemnified Person is not entitled to be indemnified as authorized in the
preceding subsection.

     (d) The provisions of Section 7 shall survive the termination of this Trust
Agreement or the earlier resignation or removal of the Fiduciary Indemnified
Persons.

8. The number of Trustees initially shall be three (3) and thereafter the number
of Trustees shall be such number as shall be fixed from time to time by a
written instrument signed by the Depositor, who may increase or decrease the
number of Trustees; provided, however, that, to the extent required by the
Business Trust Act, one Trustee shall either be a natural person who is a
resident of Delaware or, if not a natural person, an entity which has its
principal place of business in the State of Delaware and otherwise meets the
requirements of applicable Delaware law. Subject to the foregoing, the Depositor
is entitled to appoint or remove without cause any Trustee at any time. The
Trustees may resign upon thirty (30) days' prior written notice to the
Depositor; provided, however, that no resignation of the Delaware Trustee shall
be effective until a successor Delaware Trustee has been appointed by the
Administrative Trustees and has accepted such appointment by an instrument
executed by such successor Delaware Trustee and delivered to the Administrative
Trustees, the Depositor and Wilmington Trust Company. In the event a successor
Delaware Trustee is not appointed within thirty (30) days of giving notice of
resignation, the Delaware Trustee shall have a right to petition a court of
competent jurisdiction to appoint a successor Delaware Trustee at the cost of
the Trust.

<PAGE>

9. This Trust Agreement shall be governed by, and construed in accordance with,
the laws of the State of Delaware (without regard to conflict of laws
principles).

10. This Trust Agreement may be executed in one or more counterparts.

11. The Trust may terminate without issuing any Trust Securities at the election
of the Depositor.

     IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement to
be duly executed as of the day and year first above written.
