        WITH RESPECT TO ITS COMMON STOCK AND CUMULATIVE PREFERRED STOCK
                            ------------------------
 
    THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
TIME, ON FRIDAY, FEBRUARY 28, 1997, UNLESS THE OFFER IS EXTENDED.
                            ------------------------
 
    American Electric Power Company, Inc., a New York corporation ("AEP"),
invites the holders of each series of cumulative preferred stock listed above
(each a "Series of Preferred," and the holder thereof a "Preferred Shareholder")
of Appalachian Power Company, a Virginia corporation and direct utility
subsidiary of AEP ("APCo"), to tender any and all of their shares of a Series of
Preferred ("Shares") for purchase at the purchase price per Share listed above
plus accrued and unpaid dividends for the Shares tendered, net to the seller in
cash, upon the terms and subject to the conditions set forth in this Offer to
Purchase and Proxy Statement and in the accompanying Letter of Transmittal
(which together constitutes the "Offer"). AEP will purchase any and all Shares
validly tendered and not withdrawn, upon the terms and subject to the conditions
of the Offer. See "Terms of the Offer -- Certain Conditions of the Offer" and
"Terms of the Offer -- Extension of Tender Period; Termination; Amendments."
 
    THE OFFER FOR A SERIES OF PREFERRED IS NOT CONDITIONED UPON ANY MINIMUM
NUMBER OF SHARES OF SUCH SERIES OF PREFERRED BEING TENDERED AND IS INDEPENDENT
OF THE OFFER FOR ANY OTHER SERIES OF PREFERRED. THE OFFER, HOWEVER, IS
CONDITIONED UPON, AMONG OTHER THINGS, THE PROPOSED AMENDMENT, AS DESCRIBED
BELOW, BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED HEREIN).
SEE "TERMS OF THE OFFER -- CERTAIN CONDITIONS OF THE OFFER."
 
    Concurrently with the Offer, the Board of Directors of APCo is soliciting
proxies for use at the Special Meeting of Shareholders of APCo to be held at
AEP's principal office, 1 Riverside Plaza, Columbus, Ohio 43215, on February 28,
1997 at 4:00 p.m., New York City time, or any adjournment or postponement of
such meeting (the "Special Meeting"). The Special Meeting is being held to
consider an amendment (the "Proposed Amendment") to APCo's Amended Articles of
Incorporation (the "Articles") which would remove a provision of the Articles
that limits APCo's ability to issue debt. WHILE PREFERRED SHAREHOLDERS WHO WISH
TO TENDER THEIR SHARES PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE
PROPOSED AMENDMENT, THE OFFER IS CONDITIONED UPON THE PROPOSED AMENDMENT BEING
APPROVED AND ADOPTED AT THE SPECIAL MEETING. IN ADDITION, PREFERRED SHAREHOLDERS
OF RECORD HAVE THE RIGHT TO VOTE FOR OR AGAINST THE PROPOSED AMENDMENT
REGARDLESS OF WHETHER THEY TENDER THEIR SHARES. IF THE PROPOSED AMENDMENT IS
APPROVED AND ADOPTED BY APCO'S SHAREHOLDERS, APCO WILL MAKE A SPECIAL CASH
PAYMENT IN THE AMOUNT OF $1.00 PER SHARE TO EACH PREFERRED SHAREHOLDER WHO VOTED
IN FAVOR OF THE PROPOSED AMENDMENT, PROVIDED THAT SUCH SHARES HAVE NOT BEEN
TENDERED PURSUANT TO THE OFFER. THOSE PREFERRED SHAREHOLDERS WHO VALIDLY TENDER
THEIR SHARES WILL BE ENTITLED ONLY TO THE PURCHASE PRICE PER SHARE LISTED ABOVE.
                            ------------------------
 
    The Company will pay to a Soliciting Dealer (as defined herein) a
solicitation fee for Shares tendered, accepted for payment and paid for pursuant
to the Offer, subject to certain conditions. See "Fees and Expenses Paid to
Dealers."
 
    THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION (THE "SEC") NOR HAS THE SEC PASSED UPON THE FAIRNESS OR
MERITS OF THIS TRANSACTION NOR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION
CONTAINED IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.
                            ------------------------
 
    NEITHER AEP, APCO, THEIR RESPECTIVE BOARDS OF DIRECTORS, NOR ANY OF THEIR
RESPECTIVE OFFICERS MAKES ANY RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO
WHETHER TO TENDER ANY OR ALL SHARES. EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR
HER OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO
TENDER.
 
    APCO'S BOARD OF DIRECTORS RECOMMENDS VOTING FOR THE PROPOSED AMENDMENT.
                            ------------------------

                             $105.50 per 7.80% Share
 
Independent Offer..........  The Offer for one Series of Preferred is
                             independent of the Offer for any other Series of
                             Preferred. The Offer is not conditioned upon any
                             minimum number of Shares of the applicable Series
                             of Preferred being tendered. Preferred Shareholders
                             who wish to tender their Shares are not required to
                             vote in favor of the Proposed Amendment. The Offer
                             is subject, however, to shareholder approval of the
                             Proposed Amendment and certain other conditions.
 
Expiration Date of the
Offer......................  The Offer expires at 5:00 p.m., New York City time,
                             February 28, 1997, unless extended (the "Expiration
                             Date").
 
How to Tender Shares.......  See "Terms of the Offer -- Procedure for Tendering
                             Shares". For further information, call the
                             Information Agent or the Dealer Managers or consult
                             your broker for assistance.
 
Withdrawal Rights..........  Tendered Shares of any Series of Preferred may be
                             withdrawn at any time until the Expiration Date
                             with respect to such Series of Preferred and,
                             unless previously accepted for payment, may also be
                             withdrawn after March 28, 1997. See "Terms of the
                             Offer -- Withdrawal Rights."

Purpose of the Offer.......  AEP is making the Offer because AEP believes that
                             the purchase of Shares is economically attractive
                             to APCo and indirectly to AEP and its shareholders.
                             In addition, the Offer gives Preferred Shareholders
                             the opportunity to sell their Shares at a price
                             which AEP believes to be a premium over the market
                             price and without the usual transaction costs
                             associated with a market sale. See "Purpose of the
                             Offer; Certain Effects of the Offer."
 
Dividends..................  APCo has declared the regular quarterly dividend on
                             each Series of Preferred to be paid on February 1,
                             1997 to holders of record as of the close of
                             business on January 9, 1997 (the "February 1997
                             Dividend"). A tender and purchase of Shares
                             pursuant to the Offer will not deprive a Preferred
                             Shareholder of his or her right to receive the
                             February 1997 Dividend on his or her Shares held of
                             record as of the close of business on January 9,
                             1997. Tendering Preferred Shareholders will be
                             entitled to any dividends accrued prior to the
                             Payment Date (as defined herein) in respect of any
                             later dividend periods (or any portion thereof).
 
Brokerage Commissions......  Not payable by Preferred Shareholders.
 
Solicitation Fee...........  AEP will pay to each designated Soliciting Dealer
                             (as defined herein) a solicitation fee of $1.50 per
                             Share for Shares of the 4-1/2% Series that are
                             tendered, accepted for payment and paid for
                             pursuant to the Offer (except that for transactions
                             for beneficial owners equal to or exceeding 5,000
                             Shares, AEP will pay a solicitation fee of $1.00
                             per Share for Shares of the 4-1/2% Series). AEP
                             will pay a solicitation fee of $0.50 per share for
                             Shares of the 5.90% Series, the 5.92% Series, the
                             6.85% Series and the 7.80% Series which are
                             tendered, accepted for payment and paid for
                             pursuant to the Offer; provided, however, that any
                             fee payable pursuant to this sentence shall be paid
                             80% to the Dealer Managers and 20% to any
                             designated Soliciting Dealer (which may be a Dealer
                             Manager). APCo will pay to each designated
                             Soliciting Dealer a separate fee of $0.50 per Share
                             for Shares of the 4 1/2% Series that are not
                             tendered pursuant to the Offer but which are voted
                             in favor of the Proposed Amendment. A Soliciting
                             Dealer will not be entitled to a solicitation fee
                             or a separate fee for Shares beneficially owned by
                             such Soliciting Dealer.
 
Proposed Amendment.........  Concurrently with the Offer, the Board of Directors
                             of APCo is soliciting proxies for use at the
                             Special Meeting of Shareholders of APCo. The
                             Special Meeting is being held to consider an
                             amendment to APCo's Articles which would remove a
                             provision that limits APCo's ability to issue debt.
                             If the Proposed Amendment is approved by the
                             shareholders, the clause of the Articles that
                             places restrictions on APCo's ability to issue or
                             assume indebtedness will be eliminated with respect
                             to any Shares that remain outstanding after the
                             consummation of the Offer. See "Purpose of the
                             Offer; Certain Effects of the Offer."
 
Record Date................  January 27, 1997
 
Special Cash Payment.......  Preferred Shareholders of record have the right to
                             vote for or against the Proposed Amendment
                             regardless of whether they tender their Shares. If
                             the Proposed Amendment is approved and adopted by
                             APCo's shareholders, APCo will make a special cash
                             payment of $1.00 per Share to each Preferred
                             Shareholder who voted in favor of the Proposed
                             Amendment but who did not tender his or her Shares
                             (the "Special Cash
 
                                        5

                             accrued and unpaid prior to the Payment Date.
 
Stock Transfer Tax.........  Except as described herein, AEP will pay or cause
                             to be paid any stock transfer taxes with respect to
                             the sale and transfer of any Shares to it or its
                             order pursuant to the Offer. See Instruction 6 of

                               TERMS OF THE OFFER
 
NUMBER OF SHARES; PURCHASE PRICES; EXPIRATION DATE; DIVIDENDS
 
     Upon the terms and subject to the conditions described herein and in the
applicable Letter of Transmittal, AEP will purchase any and all Shares that are
validly tendered on or prior to the applicable Expiration Date (and not properly
withdrawn in accordance with "Terms of the Offer -- Withdrawal Rights") at the
purchase price per Share listed on the front cover of this Offer to Purchase and
Proxy Statement for the Shares tendered, plus accrued and unpaid dividends for
the Shares tendered to the Payment Date, net to the seller in cash. See "Terms
of the Offer -- Certain Conditions of the Offer" and "Terms of the Offer --

Shares of the 5.90% Series of Preferred; 600,000 Shares of the 5.92% Series of
Preferred; 300,000 Shares of the 6.85% Series of Preferred; and 500,000 Shares
of the 7.80% Series of Preferred.
 
     THE OFFER FOR A SERIES OF PREFERRED IS NOT CONDITIONED UPON ANY MINIMUM
NUMBER OF SHARES OF SUCH SERIES OF PREFERRED BEING TENDERED AND IS INDEPENDENT
OF THE OFFER FOR ANY OTHER SERIES OF PREFERRED. THE OFFER, HOWEVER, IS
CONDITIONED UPON, AMONG OTHER THINGS, THE PROPOSED AMENDMENT, AS DESCRIBED
HEREIN, BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING. SEE "TERMS OF THE
OFFER -- CERTAIN CONDITIONS OF THE OFFER."
 
     The Offer is being sent to all persons in whose names Shares are registered
on the books of APCo as of the close of business on January 27, 1997 and
transferees of such persons. Only a record holder of Shares on the Record Date
may vote in person or by proxy at the Special Meeting. No record date is fixed
for determining which persons are permitted to tender Shares. Any person who is
the beneficial owner but not the record holder of Shares must arrange for the
record transfer of such Shares prior to tendering.
 
     With respect to each Series of Preferred, the Expiration Date is the later
of 5:00 p.m. New York City time, on February 28, 1997 or the latest time and
date to which the Offer with respect to such Series of Preferred is extended.
AEP expressly reserves the right, in its sole discretion, and at any time and/or
from time to time, to extend the period of time during which the Offer for any
Series of Preferred is open, by giving oral or written notice of such extension
to the Depositary and making a public announcement thereof, without extending
the period of time during which the Offer for any other Series of Preferred is
open. There is no assurance whatsoever that AEP will exercise its right to
extend the Offer for any Series of Preferred. If AEP decides, in its sole
discretion, to (i) decrease the number of Shares of any Series of Preferred
being sought, (ii) increase or decrease the consideration offered in the Offer
to holders of any Series of Preferred or (iii) increase or decrease the
Soliciting Dealers' fees and, at the time that notice of such increase or
decrease is first published, sent or given to holders of such Series of
Preferred in the manner specified herein, the Offer for such Series of Preferred
is scheduled to expire at any time earlier than the tenth business day from the
date that such notice is first so published, sent or given, such Offer will be
extended until the expiration of such ten-business-day period. For purposes of
the Offer, a "business day" means any day other than a Saturday, Sunday or
federal holiday and consists of the time period from 12:00 a.m. through 11:59
p.m., New York City time.
 
     NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS WILL BE ACCEPTED.
 
     The February 1997 Dividend has been declared on each Series of Preferred,
payable February 1, 1997 to holders of record as of the close of business on
January 9, 1997. A tender and purchase of Shares pursuant to the Offer will not
deprive such Preferred Shareholder of his or her right to receive the February
1997 Dividend on his or her Shares, regardless of when such tender is made.
Tendering Preferred Shareholders will be entitled to any dividends accrued prior
to the Payment Date in respect of any later dividend periods (or any portion
thereof).

     "Guaranteed Delivery Procedure" below.
 
     A tender of Shares made pursuant to any method of delivery set forth herein
or in the Letter of Transmittal will constitute a binding agreement between the
tendering holder and AEP upon the terms and subject to the conditions of the
Offer.
 
     The Depositary will establish an account with respect to the Shares at The
Depository Trust Company and the Philadelphia Depository Trust Company (each a
"Book-Entry Transfer Facility") for purposes of the Offer within two business
days after the date of this Offer to Purchase and Proxy Statement, and any
financial institution that is a participant in the system of a Book-Entry
Transfer Facility may make delivery of Shares by causing such Book-Entry
Transfer Facility to transfer such Shares into the Depositary's account in
accordance with the procedures of such Book-Entry Transfer Facility. Although
delivery of Shares may be effected through book-entry transfer, such delivery
must be accompanied by either (i) a properly completed and duly executed Letter
of Transmittal, together with any required signature guarantees and any other
required documents or (ii) an Agent's Message (as hereinafter defined) and, in
any case, must be received by the Depositary at one of its addresses set forth
on the back cover of this Offer to Purchase and Proxy Statement on or prior to
the Expiration Date. DELIVERY OF SUCH LETTER OF TRANSMITTAL AND ANY OTHER
REQUIRED DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY OR TO AEP DOES NOT
CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
     The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility, received by the Depositary and forming a part of the
book-entry transfer when a tender is initiated, which states that such
Book-Entry Transfer Facility has received an express acknowledgment from a
participant tendering Shares that such participant has received and agrees to be
bound by the terms of the Letter of Transmittal and that AEP may enforce such
agreement against such participant.
 
     Except as otherwise provided below, all signatures on a Letter of
Transmittal must be guaranteed by a firm that is a member of a registered
national securities exchange or the National Association of Securities Dealers,
Inc. ("NASD"), or by a commercial bank or trust company having an office or
correspondent in the United States that is a participant in an approved
Signature Guarantee Medallion Program (each of the foregoing being referred to
as an "Eligible Institution"). Signatures on a Letter of Transmittal need not be
guaranteed if (a) the Letter of Transmittal is signed by the registered owner of
the shares tendered therewith and such owner has not completed the box entitled
"Special Payment Instructions" or the box entitled "Special Delivery
Instructions" on the Letter of Transmittal or (b) such Shares are tendered for
the account of an Eligible Institution. See Instructions 1 and 5 of the Letter
of Transmittal. If Shares are registered in the name of a person other than the
signatory on the Letter of Transmittal, or if unpurchased Shares are to be
issued to a person other than the registered holder(s), the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered holder(s) appear on the Shares
with the signature(s) on the Shares or stock powers guaranteed as stated above.
See Instructions 4, 6 and 7 to the Letter of Transmittal.
 
     Guaranteed Delivery Procedure.  If a Preferred Shareholder desires to
tender Shares pursuant to the Offer and such Preferred Shareholder's
certificates are not immediately available or the procedures for book-entry
transfer cannot be completed on a timely basis or time will not permit all
required documents to reach
 
                                        8
<PAGE>   9
 
the Depositary prior to the Expiration Date, such Shares may nevertheless be
tendered if all of the following guaranteed delivery procedures are complied
with:
 
          (i) such tender is made by or through an Eligible Institution;
 
          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by AEP and APCo herewith, is
     received (with any required signatures or signature guarantees) by the
     Depositary as provided below on or prior to the Expiration Date; and
 
          (iii) the certificates for all tendered Shares in proper form for
     transfer or a Book-Entry Confirmation with respect to all tendered Shares,
     together with a properly completed and duly executed Letter of Transmittal
     and any other documents required by the Letter of Transmittal, are received
     by the Depositary no later than 5:00 p.m., New York City time, within three
     business days after the date of execution of such Notice of Guaranteed
     Delivery.
 
     THE NOTICE OF GUARANTEED DELIVERY MAY BE DELIVERED BY HAND OR MAILED TO THE
DEPOSITARY AND MUST INCLUDE AN ENDORSEMENT BY AN ELIGIBLE INSTITUTION IN THE
FORM SET FORTH IN SUCH NOTICE OF GUARANTEED DELIVERY.
 
     In all cases, Shares shall not be deemed validly tendered unless a properly
completed and duly executed Letter of Transmittal or, if applicable, an Agent's
Message, is received by the Depositary.
 
     Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer in all cases will be made only after timely
receipt by the Depositary of certificates for (or an Agent's Message with
respect to) such Shares, a Letter of Transmittal, properly completed and duly
executed, with any required signature guarantees, and all other documents
required by the Letter of Transmittal.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING PREFERRED SHAREHOLDER. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
BECAUSE IT IS THE TIME OF RECEIPT, NOT THE TIME OF MAILING, WHICH DETERMINES
WHETHER A TENDER HAS BEEN MADE PRIOR TO THE EXPIRATION DATE, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY.
 
     TO AVOID FEDERAL INCOME TAX BACKUP WITHHOLDING EQUAL TO 31% OF THE GROSS
PAYMENTS MADE PURSUANT TO THE OFFER, EACH TENDERING PREFERRED SHAREHOLDER WHO IS
A UNITED STATES PERSON MUST NOTIFY THE DEPOSITARY OF SUCH PREFERRED
SHAREHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER AND PROVIDE CERTAIN OTHER
INFORMATION BY PROPERLY COMPLETING AND EXECUTING THE SUBSTITUTE FORM W-9
INCLUDED IN THE LETTER OF TRANSMITTAL (OR, IN THE CASE OF A FOREIGN PREFERRED
SHAREHOLDER, FORM W-8 OBTAINABLE FROM THE DEPOSITARY). SEE "CERTAIN FEDERAL
INCOME TAX CONSEQUENCES."
 
     EACH PREFERRED SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE TAX CONSEQUENCES OF THE OFFER.
 
     All questions as to the form of documents and the validity, eligibility
(including the time of receipt) and acceptance for payment of any tender of
Shares will be determined by AEP, in its sole discretion, and its determination
will be final and binding. AEP reserves the absolute right to reject any or all
tenders of Shares that (i) it determines are not in proper form or (ii) the
acceptance for payment of or payment for which may, in the opinion of AEP's
counsel, be unlawful. AEP also reserves the absolute right to waive any defect
or irregularity in any tender of Shares. None of AEP, APCo, the Dealer Managers,
the Depositary, the Information Agent or any other person will be under any duty
to give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice.

WITHDRAWAL RIGHTS
 
     Tenders of Shares made pursuant to the Offer may be withdrawn at any time
prior to the Expiration Date. Thereafter, such tenders are irrevocable, except
that they may be withdrawn after March 28, 1997, unless previously accepted for
payment as provided in this Offer to Purchase and Proxy Statement.
 
     To be effective, a written notice of withdrawal must be timely received by
the Depositary, at one of its addresses set forth on the back cover of this
Offer to Purchase and Proxy Statement, and must specify the name of the person
who tendered the Shares to be withdrawn and the number of Shares to be
withdrawn. If the Shares to be withdrawn have been delivered to the Depositary,
a signed notice of withdrawal with signatures guaranteed by an Eligible
Institution (except in the case of Shares tendered by an Eligible Institution)
must be submitted prior to the release of such Shares. In addition, such notice
must specify, in the case of Shares tendered by delivery of certificates, the
name of the registered owner (if different from that of the tendering Preferred
Shareholder) and the serial numbers shown on the particular certificates
evidencing the Shares to be withdrawn or, in the case of Shares tendered by
book-entry transfer, the name and number of the account at the Book-Entry
Transfer Facility to be credited with the withdrawn Shares and the name of the
registered holder (if different from the name of such account). Withdrawals may
not be rescinded, and Shares withdrawn will thereafter be deemed not validly
tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered
by again following one of the procedures described in "Terms of the Offer --
Procedure for Tendering Shares" at any time prior to the Expiration Date.
 
     All questions as to the form and validity (including time of receipt) of
any notice of withdrawal will be determined by AEP, in its sole discretion, and
its determination will be final and binding. None of AEP, APCo, the Dealer
Managers, the Depositary, the Information Agent or any other person will be
under any duty to give notification of any defect or irregularity in any notice
of withdrawal or will incur any liability for failure to give any such
notification.
 
ACCEPTANCE OF SHARES FOR PAYMENT AND PAYMENT OF PURCHASE PRICE AND DIVIDENDS
 
     Upon the terms and subject to the conditions of the Offer, and as promptly
as practicable after the Expiration Date, AEP will accept for payment (and
thereby purchase) and pay for Shares validly tendered and not withdrawn as
permitted in "Terms of the Offer -- Withdrawal Rights." Thereafter, payment for
all Shares validly tendered on or prior to the Expiration Date and accepted
pursuant to the Offer will be made by the Depositary by check as promptly as
practicable after the Expiration Date. In all cases, payment for Shares accepted
for payment pursuant to the Offer will be made promptly but only after timely
receipt by the Depositary of certificates for such Shares (or of an Agent's
Message), a properly completed and duly executed Letter of Transmittal and any
other required documents.
 
     For purposes of the Offer, AEP will be deemed to have accepted for payment
(and thereby purchased) Shares that are validly tendered and not withdrawn as,
if and when it gives oral or written notice to the Depositary of its acceptance
for payment of such Shares. AEP will pay for Shares that it has purchased
pursuant to the Offer by depositing the purchase price therefor plus accrued and
unpaid dividends thereon with the Depositary, which will act as agent for
tendering Preferred Shareholders for the purpose of receiving payment from AEP
and transmitting payment to tendering Preferred Shareholders. Under no
circumstances will interest be paid on amounts to be paid to tendering Preferred
Shareholders, regardless of any delay in making such payment.
 
     Certificates for all Shares not validly tendered will be returned or, in
the case of Shares tendered by book-entry transfer, such Shares will be credited
to an account maintained with a Book-Entry Transfer Facility, as promptly as
practicable, without expense to the tendering Preferred Shareholder.
 
     If certain events occur, AEP may not be obligated to purchase Shares
pursuant to the Offer. See "Terms of the Offer -- Certain Conditions of the
Offer."
 
     AEP will pay or cause to be paid any stock transfer taxes with respect to
the sale and transfer of any Shares to it or its order pursuant to the Offer.
If, however, payment of the purchase price is to be made to, or Shares not
tendered or not purchased are to be registered in the name of, any person other
than the registered
 
                                       10
<PAGE>   11
 
owner, or if tendered Shares are registered in the name of any person other than
the person signing the Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered owner, such other person or otherwise)
payable on account of the transfer to such person will be deducted from the
purchase price unless satisfactory evidence of the payment of such taxes, or
exemption therefrom, is submitted. See Instruction 6 of the accompanying Letter
of Transmittal.
 
CERTAIN CONDITIONS OF THE OFFER
 
     AEP WILL NOT BE REQUIRED TO ACCEPT FOR PAYMENT OR PAY FOR ANY SHARES
TENDERED IF THE PROPOSED AMENDMENT IS NOT APPROVED AND ADOPTED AT THE SPECIAL
MEETING.
 
     PREFERRED SHAREHOLDERS OF RECORD HAVE THE RIGHT TO VOTE FOR OR AGAINST THE
PROPOSED AMENDMENT REGARDLESS OF WHETHER THEY TENDER THEIR SHARES. IF THE
PROPOSED AMENDMENT IS APPROVED AND ADOPTED, APCO WILL MAKE A SPECIAL CASH
PAYMENT TO EACH PREFERRED SHAREHOLDER WHO VOTED IN FAVOR OF THE PROPOSED
AMENDMENT, PROVIDED THAT THEIR SHARES HAVE NOT BEEN TENDERED PURSUANT TO THE
OFFER. PREFERRED SHAREHOLDERS WHO TENDER THEIR SHARES WILL ONLY BE ENTITLED TO
THE PURCHASE PRICE PER SHARE LISTED ON THE FRONT COVER OF THIS OFFER TO PURCHASE
AND PROXY STATEMENT.
 
     In addition, notwithstanding any other provision of the Offer, AEP will not
be required to accept for payment or pay for any Shares tendered, and may
terminate or amend the Offer (by oral or written notice to the Depositary and
timely public announcement) or may postpone (subject to the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") for prompt
payment for or return of Shares) the acceptance for payment of, or payment for,
Shares tendered, if at any time after January 29, 1997, and at or before the
Expiration Date, any of the following shall have occurred (which shall not have
been waived by AEP):
 
          (a) there shall have been threatened, instituted or pending any action
     or proceeding by any government or governmental, regulatory or
     administrative agency, authority or tribunal or any other person, domestic
     or foreign, or before any court, authority, agency or tribunal that (i)
     challenges the acquisition of Shares pursuant to the Offer or otherwise in
     any manner relates to or affects the Offer or (ii) in the reasonable
     judgment of AEP, would or might materially and adversely affect the
     business, condition (financial or otherwise), income, operations or
     prospects of AEP and its subsidiaries taken as a whole, or otherwise
     materially impair in any way the contemplated future conduct of the
     business of AEP or any of its subsidiaries or materially impair the Offer's
     contemplated benefits to AEP;
 
          (b) there shall have been any action threatened, pending or taken, or
     approval withheld, or any statute, rule, regulation, judgment, order or
     injunction threatened, proposed, sought, promulgated, enacted, entered,
     amended, enforced or deemed to be applicable to the Offer or AEP or any of
     its subsidiaries, by any legislative body, court, authority, agency or
     tribunal that, in AEP's reasonable judgment, would or might directly or
     indirectly (i) make the acceptance for payment of, or payment for, some or
     all of the Shares illegal or otherwise restrict or prohibit consummation of
     the Offer; (ii) delay or restrict the ability of AEP, or render AEP unable,
     to accept for payment or pay for some or all of the Shares; (iii)
     materially impair the contemplated benefits of the Offer to AEP or APCo
     (including materially increasing the effective interest cost of certain
     types of unsecured debt); or (iv) materially affect the business, condition
     (financial or otherwise), income, operations or prospects of AEP and its
     subsidiaries taken as a whole, or otherwise materially impair in any way
     the contemplated future conduct of the business of AEP or any of its
     subsidiaries;
 
          (c) there shall have occurred (i) any significant decrease in the
     market price of the Shares; (ii) any change in the general political,
     market, economic or financial conditions in the United States or abroad
     that, in the reasonable judgment of AEP, would or might have a material
     adverse effect on AEP's business, operations, prospects or ability to
     obtain financing generally or the trading in the Shares or other
 
                                       11
<PAGE>   12
 
     equity securities of AEP; (iii) the declaration of a banking moratorium or
     any suspension of payments in respect of banks in the United States or any
     limitation on, or any event that, in AEP's reasonable judgment, would or
     might affect the extension of credit by lending institutions in the United
     States; (iv) the commencement of war, armed hostilities or other
     international or national calamity directly or indirectly involving the
     United States; (v) any general suspension of trading in, or limitation on
     prices for, securities on any national securities exchange or in the
     over-the-counter market; (vi) in the case of any of the foregoing existing
     at the time of the commencement of the Offer, in AEP's reasonable judgment,
     a material acceleration or worsening thereof; (vii) any decline in either
     the Dow Jones Industrial Average or the Standard and Poor's Composite 500
     Stock Index by an amount in excess of 15% measured from the close of
     business on January 29, 1997; or (viii) a decline in the ratings accorded
     any of AEP's or APCo's securities by Standard & Poor's Rating Services
     ("S&P"), Moody's Investors Service, Inc. ("Moody's") or Duff & Phelps, Inc.
     ("D&P") or that S&P, Moody's or D&P has announced that it has placed any
     such rating under surveillance or review with negative implications.
 
          (d) any tender or exchange offer with respect to some or all of the
     Shares (other than the Offer) or other equity securities of AEP, or a
     merger, acquisition or other business combination proposal for AEP, shall
     have been proposed, announced or made by any person or entity;
 
          (e) there shall have occurred any event or events that have resulted,
     or, in AEP's reasonable judgment, may result, in an actual or threatened
     change in the business, condition (financial or otherwise), income,
     operations, stock ownership or prospects of AEP and its subsidiaries; or
 
          (f) the Securities and Exchange Commission (the "SEC") shall have
     withheld approval, under the Holding Company Act, of the acquisition of the
     Shares by AEP pursuant to the Offer or the approval and adoption of the
     Proposed Amendment at the Special Meeting or the issuance of short-term
     debt by AEP and/or APCo;
 
and, in the sole judgment of AEP, such event or events make it undesirable or
inadvisable to proceed with the Offer or with such acceptance for payment or
payment. With respect to the approval of the SEC referenced in clause (f) above,
the SEC must find that the acquisition of the Shares by AEP is not detrimental
to the public interest or the interests of the investors or consumers, and that
the consideration paid in connection with the acquisition and the adoption of
the Proposed Amendment, including fees, commissions and other remuneration, is
reasonable.
 
     The foregoing conditions (including the condition that the Proposed
Amendment be approved and adopted at the Special Meeting) are for the sole
benefit of AEP and may be asserted by AEP regardless of the circumstances
(including any action or inaction by AEP) giving rise to any such condition, and
any such condition may be waived by AEP, in whole or in part, at any time and
from time to time in its sole discretion. A decision by AEP to terminate or
otherwise amend any Offer, following the occurrence of any of the foregoing,
with respect to one Series of Preferred will not create an obligation on behalf
of AEP to terminate or otherwise amend in a similar manner the Offer with
respect to any other Series of Preferred. The failure by AEP at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time. Any determination by AEP concerning the
events described above will be final and binding on all parties.
 
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENTS
 
     AEP expressly reserves the right, in its sole discretion, and at any time
and/or from time to time prior to the Expiration Date, to extend the period of
time during which the Offer for any Series of Preferred is open by giving oral
or written notice of such extension to the Depositary, without extending the
period of time during which the Offer for any other Series of Preferred is open.
There can be no assurance, however, that AEP will exercise its right to extend
the Offer for any Series of Preferred. During any such extension, all Shares of
the subject Series of Preferred previously tendered will remain subject to the
Offer, except to the extent that such Shares may be withdrawn as set forth in
"Terms of the Offer -- Withdrawal Rights."
 
                                       12
<PAGE>   13
 
     AEP also expressly reserves the right, in its sole discretion, to, among
other things, terminate the Offer and not accept for payment or pay for any
Shares tendered, subject to Rule 13e-4(f)(5) under the Exchange Act, which
requires AEP either to pay the consideration offered or to return the Shares
tendered promptly after the termination or withdrawal of the Offer upon the
occurrence of any of the conditions specified in "Terms of the Offer -- Certain
Conditions of the Offer" by giving oral or written notice of such termination to
the Depositary, and making a public announcement thereof.
 
     Subject to compliance with applicable law, AEP further reserves the right,
in its sole discretion, to amend the Offer in any respect. Amendments to the
Offer may be made at any time and/or from time to time effected by public
announcement thereof, such announcement, in the case of an extension, to be
issued no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled Expiration Date. Any public announcement made
pursuant to the Offer will be disseminated promptly to Preferred Shareholders
affected thereby in a manner reasonably designed to inform such Preferred
Shareholders of such change. Without limiting the manner in which AEP may choose
to make a public announcement, except as required by applicable law, AEP shall
have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by making a release to the Dow Jones News
Service.
 
     If AEP materially changes the terms of the Offer or the information
concerning the Offer, or if it waives a material condition of the Offer, AEP
will extend the Offer to the extent required by Rules 13e-4(d)(2) and
13e-4(e)(2) under the Exchange Act. Those rules require that the minimum period
during which the Offer must remain open following material changes in the terms
of the Offer or information concerning the Offer (other than a change in price,
a change in percentage of securities sought or a change in the dealer's
solicitation fee) will depend on the facts and circumstances, including the
relative materiality of such terms or information. The SEC has stated that, in
its view, an offer should remain open for a minimum of five business days from
the date that a notice of such a material change is first published, sent or
given. If the Offer is scheduled to expire at any time earlier than the
expiration of a period ending on the tenth business day from, and including, the
date that AEP publishes, sends or gives to Preferred Shareholders a notice that
it will (i) increase or decrease the price it will pay for Shares, (ii) decrease
the percentage of Shares it seeks, or (iii) increase or decrease the soliciting
dealers' fees, the Offer will be extended until the expiration of such period of
ten business days. THE OFFER FOR EACH SERIES OF PREFERRED IS INDEPENDENT OF THE
OFFER FOR ANY OTHER SERIES OF PREFERRED. IF AEP EXTENDS OR AMENDS ANY OFFER WITH
RESPECT TO ONE SERIES OF PREFERRED FOR ANY REASON, AEP WILL HAVE NO OBLIGATION
TO EXTEND THE OFFER FOR ANY OTHER SERIES OF PREFERRED.
 
                   PROPOSED AMENDMENT AND PROXY SOLICITATION
 
INTRODUCTION
 
     This Offer to Purchase and Proxy Statement is first being mailed on or
about January 30, 1997 to the shareholders of APCo in connection with the
solicitation of proxies by the Board of Directors of APCo (the "Board") for use
at the Special Meeting. At the Special Meeting, the shareholders of record of
APCo will vote upon the Proposed Amendment to the Articles.
 
     While Preferred Shareholders who wish to tender their Shares pursuant to
the Offer are not required to vote in favor of or against the Proposed
Amendment, the Offer is conditioned upon the Proposed Amendment being approved
and adopted at the Special Meeting. In addition, Preferred Shareholders of
record have the right to vote for or against the Proposed Amendment regardless
of whether they tender their Shares. If the Proposed Amendment is approved and
adopted by APCo's shareholders, APCo will make a special cash payment in the
amount of $1.00 per Share (the "Special Cash Payment") to each Preferred
Shareholder of record who voted in favor of the Proposed Amendment, provided
that such Shares have not been tendered pursuant to the Offer. If a Preferred
Shareholder votes against the Proposed Amendment or abstains, such Preferred
Shareholder shall not be entitled to the Special Cash Payment (regardless of
whether the Proposed Amendment is approved and adopted). Those Preferred
Shareholders who validly tender their Shares will be entitled only to the
purchase price per Share listed on the front cover of this Offer to Purchase and
Proxy Statement.

VOTING SECURITIES, RIGHTS AND PROCEDURES
 
     Only holders of record of APCo's voting securities at the close of business
on January 27, 1997 (the "Record Date") will be entitled to vote in person or by
proxy at the Special Meeting. The outstanding voting securities of APCo are
divided into two classes: common stock and cumulative preferred stock. The class
of cumulative preferred stock has been issued in the five Series of Preferred
with the record holders of all Shares of the cumulative preferred stock voting
together as one class. The shares outstanding as of the Record Date, and the
vote to which each share is entitled in consideration of the Proposed Amendment,
are as follows:
 
<TABLE>
<CAPTION>
                            CLASS                              SHARES OUTSTANDING     VOTES PER SHARE
- -------------------------------------------------------------  ------------------     ---------------
<S>                                                            <C>                    <C>
Common Stock (No Par Value)..................................      13,499,500              1 vote
Cumulative Preferred Stock (No Par Value)....................       2,198,150              1 vote
</TABLE>
 
     The affirmative vote of the holders of more than two-thirds of the
outstanding shares of each of APCo's (i) common stock and (ii) cumulative
preferred stock, all series voting together as one class, is required to approve
the Proposed Amendment to be presented at the Special Meeting. Abstentions and
broker non-votes will have the effect of votes against the Proposed Amendment.
AEP HAS ADVISED APCO THAT IT INTENDS TO VOTE ALL OF THE OUTSTANDING SHARES OF
COMMON STOCK OF APCO IN FAVOR OF THE PROPOSED AMENDMENT.
 
     Votes at the Special Meeting will be tabulated preliminarily by the
Depositary. Inspectors of Election, duly appointed by the presiding officer of
the Special Meeting, will definitively count and tabulate the votes and
determine and announce the results at the Special Meeting. APCo has no
established procedure for confidential voting. There are no rights of appraisal
in connection with the Proposed Amendment.
 
PROXIES
 
     THE ENCLOSED PROXY IS SOLICITED BY APCO'S BOARD, WHICH RECOMMENDS VOTING
FOR THE PROPOSED AMENDMENT. ALL SHARES OF APCO'S COMMON STOCK WILL BE VOTED IN
FAVOR OF THE PROPOSED AMENDMENT. Shares of APCo's cumulative preferred stock
represented by properly executed proxies received at or prior to the Special
Meeting will be voted in accordance with the instructions thereon. If no
instructions are indicated, duly executed proxies will be voted in accordance
with the recommendation of the Board. It is not anticipated that any other
matters will be brought before the Special Meeting. However, the enclosed proxy
gives discretionary authority to the proxy holders named therein should any
other matters be presented at the Special Meeting, and it is the intention of
the proxy holders to act on any other matters in accordance with their best
judgment.
 
     Execution of a proxy will not prevent a shareholder from attending the
Special Meeting and voting in person. Any shareholder giving a proxy may revoke
it at any time before it is voted by delivering to the Secretary of APCo written
notice of revocation bearing a later date than the proxy, by delivering a duly
executed proxy bearing a later date, or by voting in person by ballot at the
Special Meeting. Withdrawal of Shares tendered pursuant to the Offer will not
revoke a properly executed proxy.
 
     APCo will bear the cost of the solicitation of proxies by the Board. APCo
has engaged Morrow & Co., Inc. to act as Information Agent in connection with
the solicitation of proxies for a fee of $5,900 plus reimbursement of reasonable
out-of-pocket expenses. Proxies will be solicited by mail or by telephone. In
addition, officers and employees of APCo may also solicit proxies personally or
by telephone; such persons will receive no additional compensation for these
services. The Information Agent has not been retained to make, and will not
make, solicitations or recommendations in connection with the Proposed
Amendment.
 
     APCo has requested that brokerage houses and other custodians, nominees and
fiduciaries forward solicitation materials to the beneficial owners of shares of
APCo's cumulative preferred stock held of record by such persons and will
reimburse such brokers and other fiduciaries for their reasonable out-of-pocket
expenses incurred in connection therewith.
 
     The solicitation of proxies has been approved by the SEC under the Holding
Company Act. An application has been filed with the SEC under the Holding

SPECIAL CASH PAYMENTS
 
     Subject to the terms and conditions set forth in this Offer to Purchase and
Proxy Statement, if (but only if) the Proposed Amendment is approved and adopted
by the shareholders of APCo, APCo will make a Special Cash Payment to each
Preferred Shareholder who voted in favor of the Proposed Amendment, in person by
ballot or by proxy, at the Special Meeting in the amount of $1.00 for each Share
held by such Preferred Shareholder on the Record Date which is so voted,
provided that such Shares have not been tendered pursuant to the Offer. SPECIAL
CASH PAYMENTS WILL BE MADE TO PREFERRED SHAREHOLDERS AS OF THE RECORD DATE (IF
SUCH SHARES HAVE NOT BEEN TENDERED PURSUANT TO THE OFFER) ONLY IN RESPECT OF
EACH SHARE WHICH IS VOTED FOR THE ADOPTION OF THE PROPOSED AMENDMENT; PROVIDED,
HOWEVER, THAT THOSE PREFERRED SHAREHOLDERS WHO VALIDLY TENDER THEIR SHARES WILL
BE ENTITLED ONLY TO THE PURCHASE PRICE PER SHARE LISTED ON THE FRONT COVER OF
THIS OFFER TO PURCHASE AND PROXY STATEMENT. If the Proposed Amendment is
approved and adopted, Special Cash Payments will be paid out of APCo's general
funds, promptly after the Proposed Amendment shall have become effective.
However, no accrued interest will be paid on the Special Cash Payments
regardless of any delay in making such payments.
 
     Only Preferred Shareholders on the Record Date (or their legal
representatives or attorneys-in-fact) are entitled to vote at the Special
Meeting and to receive Special Cash Payments from APCo. Any beneficial holder of
Shares who is not the registered holder of such Shares as of the Record Date (as
would be the case for any beneficial holder whose Shares are registered in the
name of such holder's broker, dealer, commercial bank, trust company or other
nominee) must arrange with the record Preferred Shareholder to execute and
deliver a proxy form on such beneficial owner's behalf. If a beneficial holder
of Shares intends to attend the Special Meeting and vote in person, such
beneficial holder must obtain a legal proxy form from his or her broker, dealer,
commercial bank, trust company or other nominee.
 
SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
     As noted above, AEP owns all the outstanding common stock of APCo.
 
     Pursuant to Section 13(d) of the Exchange Act, a beneficial owner of a
security is any person who directly or indirectly has or shares voting or
investment power over such security. No person or group is known by management
of APCo to be the beneficial owner of more than 5% of the Shares as of the
Record Date.
 
     APCo's directors and executive officers do not beneficially own any Shares
as of the Record Date. The beneficial ownership of AEP's common stock held by
each director, as well as directors and executive officers as a group, as of
December 31, 1996, is set forth in the following table. Fractions of shares have
been rounded to the nearest whole number.

BUSINESS TO COME BEFORE THE SPECIAL MEETING
 
     The following Proposed Amendment to the Articles is the only item of
business expected to be presented at the Special Meeting:
 
     To remove in its entirety ARTICLE V, Clause 7(B)(b), limiting APCo's
     ability to issue indebtedness.
 
     THE FOLLOWING STATEMENTS, UNLESS THE CONTEXT OTHERWISE REQUIRES, ARE
SUMMARIES OF THE SUBSTANCE OR GENERAL EFFECT OF A PROVISION OF THE ARTICLES, AND
ARE QUALIFIED IN THEIR ENTIRETY BY THE ARTICLES AND CLAUSE 7(B)(b) (AS DESCRIBED
BELOW).
 
EXPLANATION OF THE PROPOSED AMENDMENT
 
     Article V, Clause 7(B)(b) of the Articles currently provides that, so long
as any shares of APCo's Cumulative Preferred Stock of any series are
outstanding, without the consent of the holders of a majority of the total
number of votes which holders of the outstanding shares of APCo's Cumulative
Preferred Stock of all series are entitled to cast, APCo shall not issue or
assume any evidence of indebtedness, secured or unsecured (other than for
purposes of refunding or renewing outstanding evidences of indebtedness or
redeeming or otherwise retiring all outstanding shares of APCo's Cumulative
Preferred Stock and other than first mortgage bonds and certain other secured
indebtedness) if, immediately after such issue or assumption:
 
     (a) the total outstanding principal amount of all such indebtedness issued
     or assumed by APCo and then outstanding would exceed 20% of the aggregate
     of (1) the total principal amount of all then-outstanding bonds or other
     secured debt of APCo (other than certain bonds issued under a mortgage) and
     (2) the stated capital and surplus of APCo as stated on APCo's books; or
 
                                       16
<PAGE>   17
 
     (b) the total outstanding principal amount of all unsecured debt would
     exceed 20% of the aggregate of (1) the total principal amount of all
     then-outstanding bonds or other secured debt of APCo and (2) the stated
     capital and surplus of APCo as stated on APCo's books; or
 
     (c) the total outstanding principal amount of all unsecured debt of
     maturities of less than ten years would exceed 10% of the aggregate of (1)
     the total principal amount of all then-outstanding bonds or other secured
     debt of APCo and (2) the stated capital and surplus of APCo as stated on
     APCo's books (the "Debt Limitation Provision").
 
     The Proposed Amendment, if adopted, would eliminate in its entirety clause
7(B)(b), as set forth below, from the Articles. Unless otherwise defined,
capitalized terms used in Clause 7(B) are used as defined in the Articles.
 
     Article V, Clause 7(B) of the Articles states:
 
          "(B) So long as any shares of the Cumulative Preferred Stock of any
     series are outstanding, the Corporation shall not, without the consent
     (given by vote at a meeting called for that purpose) of the holders of a
     majority of the total number of votes which holders of the outstanding
     shares of the Cumulative Preferred Stock of all series are entitled to
     cast, unless the consent of the holders of shares having some greater
     proportion of the total vote is required:
 
             (b) Issue or assume any evidences of indebtedness, secured or
        unsecured, other than bonds or other securities representing
        indebtedness of the character described hereafter in (1), (2), (3), (4),
        (5) and (6) of this clause (b), for purposes other than the refunding or
        renewing of outstanding evidences of indebtedness theretofore issued or
        assumed by the Corporation resulting in equal or longer maturities or
        redeeming or otherwise retiring all outstanding shares of the Cumulative
        Preferred Stock, if, immediately after such issue or assumption, (I) the
        total principal amount of all such indebtedness issued or assumed by the
        Corporation and then outstanding (including the evidences of
        indebtedness then to be issued or assumed) would exceed twenty per
        centum (20%) of the aggregate of (i) the total principal amount of all
        bonds or other securities representing indebtedness of the character
        described hereafter in (1), (2), (3), (4), (5) and (6) of this clause
        (b), issued or assumed by the Corporation and then to be outstanding,
        and (ii) the stated capital and surplus of the Corporation as then to be
        stated on the books of account of the Corporation, unless such evidences
        of indebtedness are (1) bonds of the Corporation issued under the
        Mortgage of the Corporation to Bankers Trust Company and R. Gregory
        Page, as Trustees, dated as of December 1, 1940 (hereinafter referred to
        as the "bonds of the Corporation"), or (2) any bonds issued under a new
        mortgage replacing said Mortgage, dated as of December 1, 1940, or (3)
        any bonds issued under any other new mortgage of the Corporation
        provided that said Mortgage, dated as of December 1, 1940, or any
        mortgage replacing it, shall have been irrevocably closed against the
        authentication of additional bonds thereunder, or (4) any indebtedness
        secured by bonds of the Corporation or by bonds issued under any such
        new mortgage, in either case in a principal amount not in excess of the
        principal amount of such pledged bonds, or (5) any indebtedness secured
        by bonds issued under a mortgage existing at the time of acquisition on
        property acquired by the Corporation, whether by consolidation, merger,
        exchange, purchase, lease, or in any other way whatsoever, provided that
        said mortgage, or any mortgage replacing it, shall be irrevocably closed
        against the authentication of additional bonds thereunder, or (6)
        obligations to pay the purchase price of material or equipment made in
        the ordinary course of the Corporation's business, or (II) the total
        outstanding principal amount of all unsecured notes, debentures or other
        securities representing unsecured debt of the Corporation (other than
        obligations of the character described in (6) of this clause (b)) would
        thereby exceed twenty per centum (20%) of the aggregate of (i) the total
        principal amount of all bonds or other secured indebtedness of the
        Corporation, and (ii) the stated capital and surplus of the Corporation
        as then to be stated on the books of account of the Corporation, or
        (III) the total outstanding principal amount of all unsecured notes,
        debentures or other securities representing unsecured indebtedness of
        the Corporation (other than obligations of the character described in
        (6) of this clause (b)) of maturities of less than 10
 
                                       17
<PAGE>   18
 
        years would thereby exceed ten per centum (10%) of the aggregate of (i)
        the total principal amount of all bonds or other secured indebtedness of
        the Corporation, and (ii) the stated capital and surplus of the
        Corporation as then to be stated on the books of account of the
        Corporation; provided, that, for purposes of this clause (b) only, the
        payment due upon the maturity of unsecured debt having an original
        single maturity of 10 or more years or the payment due upon the final
        maturity of any unsecured serial debt which had original maturities of
        10 or more years shall not be regarded as unsecured debt of a maturity
        of less than 10 years until such payment shall be required to be made
        within 3 years;"
 
REASONS FOR THE PROPOSED AMENDMENT
 
     APCo believes that regulatory, legislative, technological and market
developments are likely to lead to a more competitive environment in the
electric utility industry. APCo and AEP's other electric utility subsidiaries
believe that they currently have a favorable competitive position because of
their relatively low costs. As competition intensifies, flexibility and cost
reduction will be even more crucial to success. Because the electric utility
industry is extremely capital intensive, control and minimization of financing
costs are of particular importance. In response to the competitive forces and
regulatory changes faced by APCo and AEP's other electric utility subsidiaries,
AEP and its public utility subsidiaries have from time to time considered, and
expect to continue to consider, various strategies designed to enhance their
competitive position and to increase their ability to adapt to and anticipate
changes in their utility business.
 
     APCo believes that adoption of the Proposed Amendment is key to financial
flexibility and capital cost reduction. If adopted, the Debt Limitation
Provision will be eliminated. Historically, APCo's debt financing generally has
been accomplished through the issuance of long-term first mortgage bonds, a
modest amount of unsecured short-term debt and long-term installment purchase
contracts for pollution control bonds. First mortgage bonds represent secured
indebtedness placing a first priority lien on substantially all of APCo's
assets. APCo's first mortgage bonds issued under its Mortgage and Deed of Trust
between APCo and its bondholders contain certain restrictive covenants with
respect to, among other things, the disposition of assets and the ability to
issue additional first mortgage bonds. Unsecured debt generally has fewer
restrictions than first mortgage bonds. Short-term debt, a low cost form of debt
available to APCo, represents one type of unsecured indebtedness. Pollution
control bond financing, a favorable type of financing due to its tax-exempt
status, is available only for very limited purposes.
 
     The Proposed Amendment will not only allow APCo to issue a greater amount
of unsecured debt, but also will allow APCo to issue a greater amount of total
debt. APCo, however, presently has no intention of issuing a greater amount of
total debt than it would have issued absent the adoption of the Proposed
Amendment, except that APCo expects to issue additional unsecured debt to fund
the purchase of the Shares from AEP. Rather, it is APCo's intention to attain
flexibility in the mix of its outstanding debt and therefore have the option to
use more short-term and other unsecured debt and less first mortgage bonds.
 
     Inasmuch as the Debt Limitation Provision contained in the Articles limits
APCo's flexibility in planning and financing its business activities, APCo
believes it ultimately will be at a competitive disadvantage if the Debt
Limitation Provision is not eliminated. The industry's new competitors (for
example, power marketers, exempt wholesale generators, independent power
producers and cogeneration facilities) generally are not subject to the type of
financing restrictions the Articles impose on APCo. Recently, several other
utilities with the same or similar charter restrictions have successfully
eliminated such provisions by soliciting their shareholders for the same or
similar amendments. In addition, some potential utility competitors, and other
AEP public utility subsidiaries, including Columbus Southern Power Company and
Kentucky Power Company, have no comparable provision restricting the issuance of
unsecured debt.
 
     Although APCo sells relatively low-cost power, APCo must continue to
explore new ways of reducing costs and enhancing flexibility. APCo believes that
the adoption of the Proposed Amendment will be in the best long-term competitive
interests of its shareholders.
 
     Financial Flexibility.  If the Proposed Amendment is adopted, APCo will
have increased flexibility (i) to choose among different types of debt financing
and (ii) to finance projects using the most cost effective means. APCo believes
that various types of unsecured debt alternatives will increase in importance as
an
 
                                       18
<PAGE>   19
 
option in financing its construction program and refinancing first mortgage
bonds. The availability and flexibility of unsecured debt is necessary to take
full advantage of changing conditions in securities markets. As a result, APCo
may increase the amount of unsecured debt to more than 20% of capitalization.
 
     In addition, although APCo's earnings currently are sufficient to meet the
earnings coverage tests that must be satisfied before issuing additional first
mortgage bonds and preferred stock, there is no guarantee that this will be true
in the future. Other utilities have been unable to issue first mortgage bonds
during certain periods because of restrictive covenants in their mortgages.
APCo's inability to issue first mortgage bonds or preferred stock in the future,
combined with the inability to issue additional unsecured debt, would limit
APCo's financing options to more costly options, including additional common
equity. Moreover, continued reliance on the issuance of first mortgage bonds
under APCo's Mortgage and Deed of Trust could limit APCo's ability in the future
to strategically redeploy its assets.
 
     Under the Debt Limitation Provision, APCo's use of unsecured short-term
debt is presently restricted. However, APCo believes that the prudent use of
such debt in excess of this provision is vital to effective financial management
of its business. Not only is unsecured short-term debt generally one of the
least expensive forms of capital, it also provides flexibility in meeting
seasonal and business cycle fluctuations in cash requirements, acts as a bridge
between issues of permanent capital and can be used when unfavorable conditions
prevail in the market for long-term capital.
 
     Lower Costs.  As previously mentioned, APCo's short-term debt issuances
generally represent one of its lowest-cost forms of financing. APCo is
reassessing its historically modest use of short-term debt. By increasing its
use of short-term debt, APCo may be able to lower its cost structure further,
thereby making its products more competitive and reducing its business risks.
However, with the Debt Limitation Provision in place, the availability and
corresponding benefits of short-term debt diminish. And although short-term debt
may expose the borrower to more volatility in interest rates, it should be noted
that the cost of short-term debt seldom exceeds the cost of other forms of
capital available at the same time.
 
     IT IS FOR ALL THE ABOVE REASONS THAT APCO'S BOARD BELIEVES THE BEST
LONG-TERM INTERESTS OF SHAREHOLDERS ARE SERVED BY, AND ENCOURAGES SHAREHOLDERS
TO VOTE FOR, THE ADOPTION OF THE PROPOSED AMENDMENT.
 
RELATIONSHIP WITH INDEPENDENT PUBLIC ACCOUNTANTS
 
     Upon recommendation of the Audit Committee of AEP's board of directors,
such board employed on January 31, 1996 Deloitte & Touche LLP as independent
public accountants for AEP and its subsidiaries, including APCo, for the year
1996. A representative of Deloitte & Touche LLP will not be present at the
Special Meeting unless prior to the day of the Special Meeting the Secretary of
APCo has received written notice from a Preferred Shareholder addressed to the
Secretary at 1 Riverside Plaza, Columbus, Ohio 43215, that such Preferred
Shareholder will attend the Special Meeting and wishes to ask questions of a
representative of Deloitte & Touche LLP.
 
                        PRICE RANGE OF SHARES; DIVIDENDS
 
     APCo's Cumulative Preferred Stock 4-1/2% Series is traded on the PSE under
the symbol "APPWM", and the 5.90% Series, 5.92% Series, 6.85% Series and 7.80%
Series are traded in the over-the-counter market under the symbols "APWRO",
"APWRP", "APWRN" and "APPWD", respectively. The last reported sale price on the
PSE and the over-the-counter market, as the case may be, as of the close of
business on January 28, 1997, for each of the Series of Preferred is shown on
the front cover of this Offer to Purchase and Proxy Statement. However,
Preferred Shareholders should be aware that there is no established trading
market for the Shares (other than the 4 1/2% Series) and that the Shares of each
Series of Preferred only trade sporadically and on a limited basis and,
therefore, the last reported sales price may not necessarily reflect the market
value of the Shares.
 
     PREFERRED SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS, IF
AVAILABLE, FOR THE SHARES.

     Dividends for a Series of Preferred are payable when, as and if declared by
APCo's Board of Directors at the rate per annum included in such title of the
Series of Preferred listed on the front cover of this Offer to Purchase and
Proxy Statement. The February 1997 Dividend has been declared on each Series of
Preferred, payable February 1, 1997 to holders of record as of the close of
business on January 9, 1997. A tender and purchase of Shares pursuant to the
Offer will not deprive such Preferred Shareholder of his or her right to receive
the February 1997 Dividend. Tendering Preferred Shareholders will be entitled to
any dividends accrued and unpaid prior to the Payment Date in respect of any
later dividend periods (or any portion thereof).
 
               PURPOSE OF THE OFFER; CERTAIN EFFECTS OF THE OFFER
 
     AEP believes that the purchase of the Shares at this time represents an
attractive economic opportunity that will benefit APCo and indirectly AEP and
its shareholders. In addition, the Offer gives Preferred Shareholders the
opportunity to sell their Shares at a price which AEP believes to be a premium
to the market price on the date of the announcement of the Offer and without the
usual transaction costs associated with a sale.
 
     After the consummation of the Offer, AEP or APCo may purchase additional
Shares on the open market, in privately negotiated transactions, through one or
more tender offers or otherwise. Any such purchases may be on the same terms as,
or on terms which are more or less favorable to holders of Shares than, the
terms of the Offer. However, Rule 13e-4(f)(6) under the Exchange Act prohibits
AEP and its affiliates (including APCo) from purchasing any Shares of a Series
of Preferred, other than pursuant to the Offer, until at least ten
 
                                       20
<PAGE>   21
 
business days after the Expiration Date with respect to that Series of
Preferred. Any future purchases of Shares by AEP or APCo would depend on many
factors, including the market price of the Shares, AEP's business and financial
position, legal restrictions on AEP's ability to purchase Shares as well as
general economic and market conditions.
 
     Preferred Shareholders are not under any obligation to tender Shares
pursuant to the Offer. The Offer does not constitute notice of redemption of any
Series of Preferred pursuant to APCo's Articles, nor does AEP or APCo intend to
effect any such redemption by making the Offer. Further, the Offer does not
constitute a waiver by APCo of any option it has to redeem Shares. The 4-1/2%
Series is not subject to mandatory redemption but presently is callable at
$110.00 per Share; commencing in 2003 and continuing through the year 2007, a
sinking fund for the 5.90% Series will require the redemption of 25,000 Shares
on November 1 of each year and the redemption of the remaining Shares
outstanding on November 1, 2008, in each case at $100 per Share; commencing in
2003 and continuing through the year 2007, a sinking fund for the 5.92% Series
will require the redemption of 30,000 Shares on November 1 of each year and the
redemption of the remaining Shares outstanding on November 1, 2008, in each case
at $100 per Share; commencing in 2000 and continuing through the date of
redemption, a sinking fund for the 6.85% Series will require the redemption of
60,000 Shares on August 1 of each year, in each case at $100 per Share, and APCo
has the noncumulative option to redeem up to 60,000 additional Shares on any
sinking fund date at a redemption price of $100 per Share; and commencing in
1998, a sinking fund for the 7.80% Series will require the redemption of 25,000
Shares at $100 per Share on or before May 1 in each year, and APCo has the
noncumulative option to redeem up to 25,000 additional Shares on any sinking
fund date at a redemption price of $100 per Share. The Shares of each Series of
Preferred have no preemptive or conversion rights.
 
     Upon liquidation or dissolution of APCo, owners of the Shares would be
entitled to receive an amount equal to the liquidation preference per share
($100 (except in the case of the 4 1/2% Series which, under certain limited
circumstances, will be $110) plus all accrued and unpaid dividends (whether or
not earned or declared) thereon to the date of payment, prior to the payment of
any amounts to the holders of APCo's common stock.
 
     Shares validly tendered to the Depositary pursuant to the Offer and not
withdrawn in accordance with the procedures set forth herein shall be held until
the Expiration Date (or returned to the extent the Offer is terminated in
accordance herewith). To the extent that the Proposed Amendment is approved and
the Shares tendered are accepted for payment and paid for in accordance with the
terms hereof, AEP intends to sell its Shares to APCo and, at that time, it is
expected that APCo will retire and cancel the Shares. However, in the event the
Proposed Amendment is not adopted at the Special Meeting, AEP may elect, but is
not obligated to, waive, subject to applicable law, such condition. In that
case, subsequent to AEP's waiver and purchase of the Shares, APCo anticipates,
as promptly as practicable thereafter, that it would call another special
meeting of its shareholders and solicit proxies therefrom for an amendment
substantially similar to the Proposed Amendment. At that meeting, AEP would vote
any Shares acquired by it pursuant to the Offer or otherwise (together with its
shares of common stock) in favor of such amendment, thereby maximizing the
prospects for the adoption of the amendment. Any such purchase of Shares by AEP
will reduce the number of Shares of each of the Series of Preferred that might
otherwise trade publicly or become available for purchase and/or sale and likely
will reduce the number of owners of Shares of each of the Series of Preferred,
which could adversely affect the liquidity and sale value of the Shares not
purchased in the Offer.
 
     Liquidity of Trading Market.  To the extent that Shares of any Series of
Preferred are tendered and accepted for payment in the Offer, the trading market
for Shares of such Series of Preferred that remain outstanding may be
significantly more limited, which might adversely affect the liquidity, market
value and price volatility of such Shares. Equity securities with a smaller
outstanding market value available for trading (the "float") may command a lower
price than would comparable equity securities with a greater float. Therefore,
the market price for Shares that are not tendered in the Offer may be affected
adversely to the extent that the amount of Shares purchased pursuant to the
Offer reduces the float. The reduced float may also make the trading price of
the Shares that are not tendered and accepted for payment more volatile.
Preferred Shareholders of the remaining Shares may attempt to obtain quotations
for the Shares from their brokers; however, there can be no assurance that any
trading market will exist for such Shares following
 
                                       21
<PAGE>   22
 
consummation of the Offer. To the extent a market continues to exist for the
Shares after the Offer, the Shares may trade at a discount compared to present
trading depending on the market for Shares with similar features, the
performance of APCo, and other factors. There is no assurance that an active
market in the Shares will exist and no assurance as to the prices at which the
Shares may trade.
 
     4-1/2% Series.  Depending on the number of Shares tendered and purchased
pursuant to the Offer, the 4-1/2% Series may no longer meet the requirements of
the PSE for trading, which may adversely affect the market for the Shares of the
4-1/2% Series. According to its published guidelines, the PSE would consider
delisting the 4-1/2% Series if, among other things, (i) the number of
publicly-held Shares of the 4-1/2% Series should fall below 200,000, (ii) the
number of Preferred Shareholders owning Shares of the 4-1/2% Series should fall
below 400 (or 300 round lot shareholders), or (iii) the aggregate market value
of the 4-1/2% Series should fall below $1,000,000. If, as a result of the
purchase of Shares pursuant to the Offer or otherwise, the 4-1/2% Series no
longer meets the requirements of the PSE for continued listing and the listing
of the 4-1/2% Series is discontinued, the market for the 4-1/2% Series could
be adversely affected.
 
     In the event of the delisting of the 4-1/2% Series currently listed on the
PSE, it is possible that such Series would continue to trade on another
securities exchange or in the over-the-counter market and that price quotations
would be reported by such exchange, by the National Association of Securities
Dealers, Inc. ("NASD") through the National Association of Securities Dealers
Automated Quotation System ("NASDAQ") or by other sources. The extent of the
public market for the 4-1/2% Series and the availability of quotations,
however, would depend upon such factors as the number of shareholders remaining
at such time, the interest in maintaining a market in the 4-1/2% Series on the
part of securities firms, the possible termination of registration under the
Exchange Act as described below, and other factors.
 
     The Shares of the 4-1/2% Series are presently "margin securities" under
the regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of such Shares. If the 4-1/2% Series
remains listed on the PSE, the Shares of the 4-1/2% Series will continue to be
"margin securities." If the 4-1/2% Series is delisted, depending upon factors
similar to those described above, the 4-1/2% Series might no longer constitute
"margin securities" for purposes of the margin regulations of the Federal
Reserve, in which case, the Shares of the 4-1/2% Series could no longer be used
as collateral for loans made by brokers.
 
     In addition, the 4-1/2% Series is currently registered under Section 12(b)
of the Exchange Act. Registration of the Shares of the 4-1/2% Series under the
Exchange Act may be terminated upon the application by APCo to the SEC if such
Shares are no longer listed on a national securities exchange. Termination of
registration of the Shares of the 4-1/2% Series under the Exchange Act would
substantially reduce the information required to be furnished by APCo to
Preferred Shareholders and could make certain provisions of the Exchange Act no
longer applicable to APCo. If registration of the 4-1/2% Series under the
Exchange Act were terminated, Shares of the 4-1/2% Series would no longer be
"margin securities" or be eligible for NASDAQ reporting. As of December 31,
1996, there were 1,773 registered holders of the 4-1/2% Series.
 
     OTC Series.  The purchase of Shares of the 5.90% Series, 5.92% Series, the
6.85% Series and the 7.80% Series (collectively, the "OTC Series") pursuant to
the Offer will reduce the number of holders of Shares of the OTC Series and the
number of such Shares that might otherwise trade publicly, and, depending upon
the number of Shares so purchased, such reduction could adversely affect the
liquidity and market value of the remaining Shares of the OTC Series held by the
public. The extent of the public market for the Shares of the OTC Series and the
availability of price quotations would, however, depend upon such factors as the
number of stockholders remaining at such time, the interest in maintaining a
market in the Shares of the OTC Series on the part of securities firms and other
factors. As of December 31, 1996, there was 1 registered holder of the 5.90%
Series, 2 registered holders of the 5.92% Series, 1 registered holder of the
6.85% Series and 3 registered holders of the 7.80% Series.
 
     Other Potential Effects of the Proposed Amendment on Preferred Shareholders
who do not Tender.  If the Proposed Amendment becomes effective, Preferred
Shareholders of Shares that are not tendered and purchased pursuant to the Offer
will no longer be entitled to the benefits of the Debt Limitation Provision,
 
                                       22
<PAGE>   23
 
which will have been deleted by the Proposed Amendment. As discussed above, the
Debt Limitation Provision places restrictions on APCo's ability to issue or
assume indebtedness. Although APCo's debt instruments may contain certain
restrictions on APCo's ability to issue or assume debt, any such restrictions
may be waived and the increased flexibility afforded APCo by the deletion of the
Debt Limitation Provision may permit APCo to take certain actions that may
increase the credit risks with respect to APCo, adversely affecting the market
price and credit rating of the remaining Shares or otherwise be materially
adverse to the interests of the remaining Preferred Shareholders. In addition,
to the extent that APCo elects to fund its purchase of the Shares by issuing
additional unsecured debt, the remaining Preferred Shareholders relative
position in APCo's capital structure could be perceived to decline, which in
turn could adversely affect the market price and credit rating of the remaining
Shares. To this end, Moody's has advised APCo that Moody's might reconsider its
rating of APCo's preferred stock, absent some mitigating factors, and
particularly in light of APCo's plan to fund the purchase of Shares from AEP
through the issuance of additional unsecured debt.
 
     Following the consummation of the Offer, the business and operations of
APCo will be continued substantially as they are currently being conducted.
Except as disclosed in this Offer to Purchase and Proxy Statement, AEP and APCo
currently have no plans or proposals that relate to or would result in: (a) the
acquisition by any person or entity of additional securities of APCo or the
disposition of securities of APCo, other than in the ordinary course of
business; (b) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving APCo or any of its subsidiaries other
than APCo's plan to merge certain inactive and immaterial coal subsidiaries; (c)
a sale or transfer of a material amount of assets of APCo or any of its
subsidiaries; (d) any change in the present Board or management of APCo; (e) any
material change in the present dividend rate or policy, or indebtedness or
capitalization of APCo; (f) any other material change in APCo's corporate
structure or business; (g) any change in APCo's Articles or By-Laws or any
actions that may impede the acquisition of control of APCo by any person; (h) a
class of equity securities of APCo being delisted from a national securities
exchange or no longer authorized to be quoted in the OTC; (i) a class of equity
securities of APCo becoming eligible for termination of registration pursuant to
Section 12(g)(4) of the Exchange Act; or (j) the suspension of APCo's obligation
to file reports pursuant to Section 15(d) of the Exchange Act.
 
     NEITHER AEP, APCO, THEIR RESPECTIVE BOARDS OF DIRECTORS, NOR ANY OF THEIR
RESPECTIVE OFFICERS MAKES ANY RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO
WHETHER TO TENDER ALL OR ANY SHARES. EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR
HER OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO
TENDER.
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     In the opinion of Simpson Thacher & Bartlett, tax counsel to AEP and APCo,
the following summary describes the principal United States federal income tax
consequences of sales of Shares pursuant to the Offer and the receipt of Special
Cash Payments in connection with the approval and adoption of the Proposed
Amendment. This summary is based on the Internal Revenue Code of 1986, as
amended to the date hereof (the "Code"), administrative pronouncements, judicial
decisions and existing and proposed Treasury Regulations, changes to any of
which subsequent to the date of this Offer to Purchase and Proxy Statement may
adversely affect the tax consequences described herein, possibly on a
retroactive basis. This summary is addressed to Preferred Shareholders who hold
Shares as capital assets within the meaning of Section 1221 of the Code. This
summary does not discuss all of the tax consequences that may be relevant to a
Preferred Shareholder in light of such Preferred Shareholder's particular
circumstances or to Preferred Shareholders subject to special rules (including
certain financial institutions, tax-exempt organizations, insurance companies,
dealers in securities or currencies, foreign persons or entities selling Shares
pursuant to the Offer who own or have owned, actually or constructively, more
than five percent of such Shares, Preferred Shareholders who acquired their
Shares pursuant to the exercise of stock options or other compensation
arrangements with APCo or Preferred Shareholders holding the Shares as part of a
conversion transaction, as part of a hedge or hedging transaction, or as a
position in a straddle for tax purposes). Preferred Shareholders should consult
their tax advisors with regard to the application of the United States federal
income tax laws to their particular
 
                                       23
<PAGE>   24
 
situations as well as any tax consequences arising under the laws of any state,
local or foreign taxing jurisdiction.
 
     As used herein, the term "United States Holder" means an owner of a Share
that is (i) for United States federal income tax purposes a citizen or resident
of the United States; (ii) a corporation, partnership or other entity created or
organized in or under the laws of the United States or of any political
subdivision thereof; (iii) an estate or for taxable years beginning on or before
December 31, 1996, in general any trust, the income of which is subject to
United States federal income taxation regardless of its source; or (iv) for
taxable years beginning after December 31, 1996 any trust if a court within the
United States is able to exercise primary supervision over the administration of
such trust and one or more United States fiduciaries have the authority to
control all substantial decisions of such trust. A "Non-United States Holder" is
a Preferred Shareholder that is not a United States Holder.
 
     Tax Considerations for Tendering Preferred Shareholders
 
     Characterization of the Sale.  A sale of Shares by a Preferred Shareholder
pursuant to the Offer will be a taxable transaction for Federal income tax
purposes.
 
     United States Holders.  A United States Holder will recognize gain or loss
equal to the difference between the tax basis of such Holder's Shares and the
amount of cash received in exchange therefor. A United States Holder's gain or
loss will be long-term capital gain or loss if the holding period for the Shares
is more than one year as of the date of the sale of such Shares. The excess of
net long-term capital gains over net short-term capital losses is taxed at a
lower rate than ordinary income for certain non-corporate taxpayers. The
distinction between capital gain or loss and ordinary income or loss is also
relevant for purposes of, among other things, limitations on the deductibility
of capital losses.
 
     Non-United States Holders.  Any gain realized upon the sale of Shares by a
Non-United States Holder pursuant to the Offer generally will not be subject to
United States Federal income tax unless (i) such gain is effectively connected
with a trade or business in the United States of the Non-United States Holder or
(ii) in the case of a Non-United States Holder who is an individual, such
individual is present in the United States for 183 days or more in the taxable
year of such sale and certain other conditions are met.
 
     A Non-United States Holder described in clause (i) above will be taxed on
the net gain derived from the sale at regular graduated United States Federal
income tax rates. If a Non-United States Holder that is a foreign corporation
falls under clause (i) above, it may also be subject to an additional "branch
profits tax" at a 30% rate (or such lower rate as may be specified by an
applicable income tax treaty). Unless an applicable tax treaty provides
otherwise, an individual Non-United States Holder described in clause (ii) above
will be subject to a flat 30% tax on the gain derived from the sale, which may
be offset by United States capital losses (notwithstanding the fact that the
individual is not considered a resident of the United States).
 
     Tax Considerations for Non-Tendering Preferred Shareholders
 
     Preferred Shareholders, whether or not they receive Special Cash Payments,
will not recognize any taxable gain or loss with respect to the Shares as a
result of the modification of the Articles by the Proposed Amendment.
 
     United States Holders.  There is no direct authority concerning the Federal
income tax consequences of the receipt of Special Cash Payments. APCo will, for
information reporting purposes, treat Special Cash Payments as ordinary
non-dividend income to recipient United States Holders.
 
     Non-United States Holders.  APCo will treat Special Cash Payments paid to a
Non-United States Holder of Shares as subject to withholding of United States
Federal income tax at a 30% rate. However, Special Cash Payments that are
effectively connected with the conduct of a trade or business by the Non-United
States Holder within the United States are not subject to the withholding tax
(provided such Non-United States Holder provides two originals of Internal
Revenue Service ("IRS") Form 4224 stating that such Special Cash Payments are so
effectively connected), but instead are subject to United States Federal income
tax on a net income basis at applicable graduated individual or corporate rates.
Any such effectively
 
                                       24
<PAGE>   25
 
connected Special Cash Payments received by a foreign corporation may, under
certain circumstances, be subject to an additional "branch profits tax" at a 30%
rate (or such lower rate as may be specified by an applicable income tax
treaty).
 
     A Non-United States Holder of Shares eligible for a reduced rate of United
States withholding tax pursuant to an income tax treaty may obtain a refund of
any excess amounts withheld by filing an appropriate claim for refund with the
IRS.
 
     Backup Withholding.  ANY TENDERING PREFERRED SHAREHOLDER WHO FAILS TO
COMPLETE AND SIGN THE SUBSTITUTE FORM W-9 THAT IS INCLUDED IN THE APPLICABLE
LETTER OF TRANSMITTAL (OR, IN THE CASE OF A FOREIGN PREFERRED SHAREHOLDER, FORM
W-8 OBTAINABLE FROM THE DEPOSITARY) MAY BE SUBJECT TO A REQUIRED FEDERAL INCOME
TAX BACKUP WITHHOLDING OF 31% OF THE GROSS PROCEEDS PAYABLE TO SUCH PREFERRED
SHAREHOLDER PURSUANT TO THE OFFER. To prevent backup United States Federal
income tax withholding with respect to the purchase price of Shares purchased
pursuant to the Offer, a United States Holder must provide the Depositary with
the Preferred Shareholder's correct taxpayer identification number and certify
that the Preferred Shareholder is not subject to backup withholding of Federal
income tax by completing the Substitute Form W-9 included in the applicable
Letter of Transmittal. Certain Preferred Shareholders (including, among others,
all corporations and certain foreign shareholders) are exempt from backup
withholding. For a corporate United States Holder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, the foreign
holder must submit a Form W-8, Certificate of Foreign Status, signed under
penalties of perjury, attesting to that Preferred Shareholder's exempt status. A
copy of Form W-8 may be obtained from the Depositary.
 
     Unless a Preferred Shareholder provides the appropriate certification,
under the applicable law and regulations concerning "backup withholding" of
Federal United States income tax, the Depositary will be required to withhold,
and will withhold, 31% of the gross proceeds otherwise payable to such Preferred
Shareholder. The amount of any backup withholding from a payment to a Preferred
Shareholder will be allowed as a credit against such Preferred Shareholder's
United States federal income tax liability and may entitle such Preferred
Shareholder to a refund, provided that the required information is furnished to
the IRS.
 
                           SOURCE AND AMOUNT OF FUNDS
 
     Assuming that AEP purchases all outstanding Shares pursuant to the Offer,
the total amount required by AEP to purchase such Shares will be approximately
$231 million, exclusive of the accrued and unpaid dividends payments, but
including fees and other expenses. AEP intends to fund the Offer through the use
of its general funds (which, in the ordinary course, include funds from APCo)
and funds borrowed pursuant to AEP's commercial paper program and committed
lines of credit, including any bank revolving credit agreements.
 
     AEP and APCo sell commercial paper directly to commercial paper dealers who
reoffer the commercial paper to investors and issue and sell short-term notes to
several domestic and foreign banks through various credit arrangements,
including revolving credit agreements or shared lines of credit. AEP and its
significant subsidiaries, including APCo, have $500 million of committed lines
of credit available for use by AEP and such subsidiaries. If necessary, AEP and
its significant subsidiaries may negotiate increases to existing credit
arrangements in order to fund the Offer.
 
               TRANSACTIONS AND AGREEMENTS CONCERNING THE SHARES
 
     Each of AEP and APCo has been advised by its directors and executive
officers that no directors or executive officers of the respective companies own
any Shares. Based upon the companies' records and upon information provided to
each company by its directors and executive officers, neither company nor, to
the knowledge of either, any of their subsidiaries, affiliates, directors or
executive officers, or associates of the
 
                                       25
<PAGE>   26
 
foregoing, has engaged in any transactions involving Shares during the 40
business days preceding the date hereof. Neither company nor, to the knowledge
of either, any of its directors or executive officers or an associate of the
foregoing is a party to any contract, arrangement, understanding or relationship
relating directly or indirectly to the Offer with any other person or entity
with respect to any securities of APCo.
 
                       FEES AND EXPENSES PAID TO DEALERS
 
     Dealer Manager Fees.  Merrill Lynch and Salomon Brothers will act as Dealer
Managers for AEP in connection with the Offer. AEP has agreed to pay the Dealer
Managers a fee of $.50 per Share for any Shares tendered, accepted for payment
and paid for pursuant to the Offer and a fee of $.50 per Share for any Shares
that are not tendered pursuant to the Offer but which vote in favor of the
Proposed Amendment. The Dealer Managers will also be reimbursed by AEP for their
reasonable out-of-pocket expenses, including attorneys' fees, and will be
indemnified against certain liabilities, including certain liabilities under the
federal securities laws, in connection with the Offer. The Dealer Managers have
rendered, are currently rendering and are expected to continue to render various
investment banking and other advisory services to AEP and APCo. The Dealer
Managers have received, and will continue to receive, customary compensation
from AEP and APCo for such services. AEP has retained First Chicago Trust
Company of New York as Depositary and Morrow & Co., Inc. as Information Agent in
connection with the Offer. The Depositary and Information Agent will receive
reasonable and customary compensation for their services and will also be
reimbursed for reasonable out-of-pocket expenses, including attorney fees. AEP
has agreed to indemnify the Depositary and Information Agent against certain
liabilities, including certain liabilities under the federal securities law, in
connection with the Offer. Neither the Depositary nor the Information Agent has
been retained to make solicitations or recommendations in connection with the
Offer.
 
     Solicited Tender Fees and Separate Fees.  Pursuant to Instruction 10 of the
accompanying Letter of Transmittal, AEP will pay to each designated Soliciting
Dealer a solicitation fee of $1.50 per Share for Shares of the 4 1/2% Series
that are tendered, accepted for payment and paid for pursuant to the Offer
(except that for transactions for beneficial owners equal to or exceeding 5,000
Shares, AEP will pay a solicitation fee of $1.00 per Share for Shares of the
4 1/2% Series). AEP will pay a solicitation fee of $0.50 per Share for Shares of
the 5.90% Series, the 5.92% Series, the 6.85% Series and the 7.80% Series which
are tendered, accepted for payment and paid for pursuant to the Offer; provided,
however, that any fee payable pursuant to this sentence shall be paid 80% to the
Dealer Managers and 20% to any designated Soliciting Dealer (which may be a
Dealer Manager). APCo will pay to each designated Soliciting Dealer a separate
fee of $0.50 per Share for Shares of the 4 1/2% Series that are not tendered
pursuant to the Offer but which are voted in favor of the Proposed Amendment. A
designated Soliciting Dealer is an entity obtaining the tender or proxy, if the
Letter of Transmittal or proxy, as the case may be, shall include its name and
it is (a) any broker or dealer in securities, including a Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the NASD, (b) any foreign broker or dealer not eligible for
membership in the NASD which agrees to conform to the NASD's Rules of Fair
Practice in soliciting tenders outside the United States to the same extent as
though it were an NASD member, or (c) any bank or trust company.
 
     No solicitation fee or separate fee (other than solicitation fees payable
to the Dealer Managers as provided above) shall be payable to a Soliciting
Dealer with respect to the tender of Shares or the vote of Shares by a holder
unless the Letter of Transmittal or proxy accompanying such tender or vote, as
the case may be, designates such Soliciting Dealer. No solicitation fee or
separate fee shall be payable to a Soliciting Dealer in respect of Shares
registered in the name of such Soliciting Dealer unless such Shares are held by
such Soliciting Dealer as nominee and such Shares are being tendered or voted
for the benefit of one or more beneficial owners identified on the Letter of
Transmittal or on the Notice of Solicited Tenders. No solicitation fee or
separate fee shall be payable to a Soliciting Dealer if such Soliciting Dealer
is required for any reason to transfer the amount of such fee to a depositing
holder (other than itself). No solicitation fee shall be paid to a Soliciting
Dealer with respect to Shares tendered for such Soliciting Dealer's own account
and no separate fee shall be paid to a Soliciting Dealer with respect to Shares
voted for such Soliciting Dealer's own account. Soliciting Dealers will not be
entitled to a solicitation fee or a separate fee for Shares beneficially owned
by
 
                                       26

such Soliciting Dealer. No broker, dealer, bank, trust company or fiduciary
shall be deemed to be the agent of AEP, APCo, the Depositary, the Information
Agent or the Dealer Managers for purposes of the Offer.
 
     Soliciting Dealers will include any of the organizations described in
clauses (a), (b) and (c) above even when the activities of such organizations in
connection with the Offer consist solely of forwarding to clients materials
relating to the Offer, including the Letter of Transmittal and tendering Shares
as directed by beneficial owners thereof. No Soliciting Dealer is required to
make any recommendation to holders of Shares as to whether to tender or refrain
from tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     Stock Transfer Taxes.  AEP will pay all stock transfer taxes, if any,
payable on account of the acquisition of Shares by AEP pursuant to the Offer,
except in certain circumstances where special payment or delivery procedures are
utilized pursuant to Instruction 6 of the accompanying Letter of Transmittal.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to American Electric Power Company, Inc., a

per Share shown on the first page hereof plus accrued and unpaid dividends
thereon, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase and Proxy Statement, dated January 30, 1997
(the "Offer to Purchase and Proxy Statement"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which as to the Shares,
together with the Offer to Purchase and Proxy Statement, constitutes the
"Offer"). WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S AMENDED
ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND PROXY
STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE PROPOSED
AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED IN THE
OFFER TO PURCHASE AND PROXY STATEMENT). See "Proposed Amendment and Proxy
Solicitation", "Terms of the Offer -- Extension of Tender Period; Termination;
Amendments" and "Terms of the Offer -- Certain Conditions of the Offer" in the
Offer to Purchase and Proxy Statement.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Shares tendered herewith in accordance with the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the undersigned hereby
sells, assigns and transfers to, or upon the order of, AEP all right, title and
interest in and to all the Shares that are being tendered hereby and hereby
constitutes and appoints First Chicago Trust Company of New York (the
"Depositary") the true and lawful agent and attorney-in-fact of the undersigned
with respect to such Shares, with full power of substitution (such power of
attorney being an irrevocable power coupled with an interest), to (a) deliver
certificates for such Shares, or transfer ownership of such Shares on the
account books maintained by the Book-Entry Transfer Facility that holds such
Shares, together, in any such case, with all accompanying evidences of transfer
and authenticity, to or upon the order of AEP, (b) present such Shares for
registration and transfer on the books of APCo and (c) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares, all in
accordance with the terms of the Offer. The Depositary will act as agent for
tendering stockholders for the purpose of receiving payment from AEP and
transmitting payment to tendering stockholders.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and that, when and to the extent the same are accepted for
payment by AEP, AEP will acquire good, marketable and unencumbered title
thereto, free and clear of all liens, restrictions, charges, encumbrances,
conditional sales agreements or other obligations relating to the sale or
transfer thereof, and the same will not be subject to any adverse claims. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or AEP to be necessary or desirable to complete the
sale, assignment and transfer of the Shares tendered hereby.
 
     All authority herein conferred or agreed to be conferred shall not be
affected by, and shall survive the death, bankruptcy or incapacity of the
undersigned, and any obligations of the undersigned hereunder shall be binding
upon the heirs, legal representatives, successors, assigns, executors and
administrators of the undersigned. Except as stated in the Offer, this tender is
irrevocable.
 
     The undersigned understands that tenders of Shares pursuant to any one of
the procedures described under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement and in the
instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer, including the undersigned's representation and
warranty that (a) the undersigned has a net long position in the Shares being
tendered within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended, and (b) the tender of such Shares complies
with such Rule 14e-4. AEP's acceptance for payment of Shares tendered pursuant
to the Offer will constitute a binding agreement between the undersigned and AEP
upon the terms and subject to the conditions of the Offer.
 
     The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase and Proxy Statement, AEP may terminate or amend the Offer
or may not be required to purchase any of the Shares tendered hereby. In either
event, the undersigned understands that certificate(s) for any Shares not
tendered or not purchased will be returned to the undersigned.

the heading "Special Delivery Instructions", please mail the check for the
purchase price of any Shares purchased and/or any certificates for Shares not
tendered or not purchased (and accompanying documents, as appropriate) to the

Instructions" are completed, please issue the check for the purchase price of
any Shares purchased and/or return any Shares not tendered or not purchased in
the name(s) of, and mail said check and/or any certificates to, the person(s) so

registered holder(s) thereof if AEP does not accept for payment any of the
Shares so tendered.

Transmittal need not be guaranteed (a) if this Letter of Transmittal is signed
by the registered holder(s) of the Shares (which term, for purposes of this
document, shall include any participant in one of the Book-Entry Transfer
Facilities whose name appears on a security position listing as the owner of
Shares) tendered herewith and such holder(s) has not completed the box above
under the heading "Special Payment Instructions" or the box above under the
heading "Special Delivery Instructions" on this Letter of Transmittal, or (b) if
such Shares are tendered for the account of an Eligible Institution. See
Instruction 5.
 
     2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used if (a) certificates are to be forwarded herewith or,
(b) delivery of Shares is to be made by book-entry transfer pursuant to the

Tendering Shares" in the Offer to Purchase and Proxy Statement. Certificates for
all physically delivered Shares, or a confirmation of a book-entry transfer into
the Depositary's account at one of the Book-Entry Transfer Facilities of all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal, and any other documents required by this Letter
of Transmittal, must be received by the Depositary at one of its addresses set
forth on the front page of this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase and Proxy Statement) with
respect to all Shares. Preferred Shareholders who wish to tender their Shares
yet who cannot deliver their Shares and all other required documents to the
Depositary on or prior to the Expiration Date must tender their Shares pursuant
to the guaranteed delivery procedure set forth under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement. Pursuant to such procedure: (a) such tender must be made by or
through an Eligible Institution, (b) a properly completed and duly executed
Notice of Guaranteed Delivery in the form provided by AEP (with any required
signature guarantees) must be received by the Depositary on or prior to the
applicable Expiration Date and (c) the certificates for all physically delivered

Transmittal and any other documents required by this Letter of Transmittal must

York Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery, all as provided under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING PREFERRED SHAREHOLDER. IF CERTIFICATES FOR
SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer -- Number of Shares; Purchase Prices; Expiration Date;
Dividends" in the Offer to Purchase and Proxy Statement. By executing this
Letter of Transmittal, the tendering stockholder waives any right to receive any
notice of the acceptance for payment of the Shares.
 
     3.  VOTING.  WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES
PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S
AMENDED ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND
PROXY STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE
PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED
IN THE OFFER TO PURCHASE AND PROXY STATEMENT). In addition, Preferred
Shareholders have the right to vote for or against the Proposed Amendment
regardless of whether they tender their Shares by casting their vote and duly
executing the proxy enclosed herewith or by voting in person at the Special
Meeting. By executing a Notice of Guaranteed Delivery, a Preferred Shareholder
is deemed to have tendered the Shares described in such Notice of Guaranteed
Delivery and to have voted such Shares in accordance with the proxy returned
therewith, if any. If no vote is indicated on an otherwise properly executed
proxy, then all Shares in respect of such proxy will be voted in favor of the
Proposed Amendment. See "Proposed Amendment and Proxy Solicitation" in the Offer
to Purchase and Proxy Statement. The Offer is being sent to all persons in whose
names Shares are registered on the books of APCo on the Record Date (as defined
in the Offer to Purchase and Proxy Statement) and transferees thereof. Only a
record holder of Shares on the Record Date may vote in person or by proxy at the
Special Meeting. No record date is fixed for determining which persons are
permitted to tender Shares. Any person who is the beneficial owner but not the
record holder of Shares must arrange for the record transfer of such Shares
prior to tendering.
 
     4.  PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all the Shares represented by any
certificate delivered to the Depositary are to be tendered, fill in the number
of Shares that are to be tendered in the box above under the heading
"Description of Shares Tendered". In such case, a new certificate for the
remainder of the Shares represented by the old certificate will be sent to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
box above under the heading "Special Payment Instructions" or "Special Delivery
Instructions", as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.

     5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND/OR NOTICE OF GUARANTEED
DELIVERY; STOCK POWERS AND ENDORSEMENTS.  If either this Letter of Transmittal
or the Notice of Guaranteed Delivery (together, the "Tender Documents") is
signed by the registered holder(s) of the Shares tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificates without alteration, enlargement or any change whatsoever.
 
     If any of the Shares tendered under either Tender Document is held of
record by two or more persons, all such persons must sign such Tender Document.
 
     If any of the Shares tendered under either Tender Document is registered in
different names or different certificates, it will be necessary to complete,
sign and submit as many separate applicable Tender Documents as there are
different registrations or certificates.
 
     If either Tender Document is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made to, or Shares
not tendered or not purchased are to be registered in the name of, any person
other than the registered holder(s). Signatures on any such certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
     If either Tender Document or any certificate or stock power is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
AEP of the authority of such person so to act must be submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, AEP
will pay or cause to be paid any stock transfer taxes with respect to the sale
and transfer of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price is to be made to, or Shares not tendered
or not purchased are to be registered in the name of, any person other than the
registered holder(s), or if tendered Shares are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s), such
other person or otherwise) payable on account of the transfer to such person
will be deducted from the purchase price unless satisfactory evidence of the
payment of such taxes, or exemption therefrom, is submitted. See "Terms of the
Offer -- Acceptance of Shares for Payment and Payment of Purchase Price and
Dividends" in the Offer to Purchase and Proxy Statement. EXCEPT AS PROVIDED IN
THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE
CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, and/or
any Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificate for Shares not tendered or not purchased are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to an address
other than that shown in the box above under the heading "Name(s) and
Address(es) of Registered Holder(s)", then the "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Preferred Shareholders tendering Shares by book-entry transfer will
have any Shares not accepted for payment returned by crediting the account
maintained by such Preferred Shareholder at the Book-Entry Transfer Facility
from which such transfer was made.
 
     8.  SUBSTITUTE FORM W-9 AND FORM W-8.  The tendering Preferred Shareholder
is required to provide the Depositary with either a correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided under
"Important Tax Information" below, or a properly completed Form W-8. Failure to
provide the information on either Substitute Form W-9 or Form W-8 may subject
the tendering Preferred Shareholder to a $50 penalty imposed by the Internal
Revenue Service and to 31% federal income tax backup withholding on the payment
of the purchase price for the Shares. The box in Part 2 of Substitute Form W-9
may be checked if the tendering Preferred Shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future. If the box in Part 2 is checked and the Depositary is not provided with
a TIN by the time of payment, the Depositary will withhold 31% on all payments
of the purchase price for the Shares thereafter until a TIN is provided to the
Depositary.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or
requests for assistance may be directed to the Information Agent or the Dealer
Managers at their respective telephone numbers and addresses listed below.
Requests for additional copies of the Offer to Purchase and Proxy Statement,
this Letter of Transmittal or other tender offer materials may be directed to
the Information Agent and such copies will be furnished promptly at AEP's
expense. Preferred Shareholders may also contact their local broker, dealer,
commercial bank or trust company for assistance concerning the Offer.

     10. SOLICITED TENDERS.  AEP will pay a solicitation fee of $1.50 per Share
(except that for transactions for beneficial owners tendering more than 5,000
Shares, AEP will pay a solicitation fee of $1.00 per Share) for any Shares
tendered, accepted for payment and paid pursuant to the Offer, covered by the
Letter of Transmittal which designates, under the heading "Solicited Tenders",
as having solicited and obtained the tender, the name of (a) any broker or
dealer in securities, including a Dealer Manager in its capacity as a dealer or
broker, which is a member of any national securities exchange or of the National
Association of Securities Dealers, Inc. (the "NASD"), (b) any foreign broker or
dealer not eligible for membership in the NASD which agrees to conform to the
NASD's Rules of Fair Practice in soliciting tenders outside the United States to
the same extent as though it were an NASD member, or (c) any bank or trust
company (each of which is referred to herein as a "Soliciting Dealer"). No such
fee shall be payable to a Soliciting Dealer with respect to the tender of Shares
by a holder unless the Letter of Transmittal accompanying such tender designates
such Soliciting Dealer. No such fee shall be payable to a Soliciting Dealer in
respect of Shares registered in the name of such Soliciting Dealer unless such
Shares are held by such Soliciting Dealer as nominee and such Shares are being
tendered for the benefit of one or more beneficial owners identified on the
Letter of Transmittal or on the Notice of Solicited Tenders (included in the
materials provided to brokers and dealers). No such fee shall be payable to a
Soliciting Dealer with respect to the tender of Shares by the holder of record,
for the benefit of the beneficial owner, unless the beneficial owner has
designated such Soliciting Dealer. If tendered Shares are being delivered by
book-entry transfer, the Soliciting Dealer must return a Notice of Solicited
Tenders to the Depositary within three business days after expiration of the
Offer to receive a solicitation fee. No such fee shall be payable to a
Soliciting Dealer if such Soliciting Dealer is required for any reason to
transfer the amount of such fee to a depositing holder (other than itself). No
such fee shall be paid to a Soliciting Dealer with respect to Shares tendered
for such Soliciting Dealer's own account. No broker, dealer, bank, trust company
or fiduciary shall be deemed to be the agent of AEP, the Depositary, the
Information Agent or the Dealer Managers for purposes of the Offer.
 
     Soliciting Dealers will include any organizations described in clauses (a),
(b) or (c) above even when the activities of such organization in connection
with the Offer consist solely of forwarding to clients materials relating to the
Offer, including this Letter of Transmittal, and rendering Shares as directed by
beneficial owners thereof. No Soliciting Dealer is required to make any
recommendation to holders of Shares as to whether to tender or refrain from
tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     11. IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by AEP, in its sole discretion, and its
determination shall be final and binding. AEP reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the opinion
of AEP's counsel, be unlawful. AEP also reserves the absolute right to waive any
of the conditions to the Offer or any defect or irregularity in any tender of
Shares and AEP's interpretation of the terms and conditions of the Offer
(including these instructions) shall be final and binding. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as AEP shall determine. None of AEP, APCo, the Dealer Managers, the
Depositary, the Information Agent or any other person shall be under any duty to
give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured or
waived.
 
     12. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
1-800-649-2153. In addition, you should advise the Depositary of any
certificate(s) you have in your possession. You will need to complete an
Affidavit of Loss with respect to the lost certificate(s) (which will be
provided by the Depositary) and pay an indemnity bond premium fee. The tender of
Shares pursuant to this Letter of Transmittal will not be valid unless prior to
the Expiration Date: (a) such procedures have been completed and a replacement
certificate for the Shares has been delivered to the Depositary or (b) a Notice
of Guaranteed Delivery has been delivered to the Depositary. See Instruction 2.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL, DULY EXECUTED, TOGETHER WITH, IF
APPLICABLE, CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER, AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY, OR, IF APPLICABLE, THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO
THE APPLICABLE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
either such Preferred Shareholder's correct TIN on Substitute Form W-9 below or
a properly completed Form W-8. If such Preferred Shareholder is an individual,
the TIN is his or her social security number. For businesses and other entities,
the number is the federal employer identification number. If the Depositary is
not provided with the correct TIN or properly completed Form W-8, the Preferred
Shareholder may be subject to a $50 penalty imposed by the Internal Revenue
Code. In addition, payments that are made to such Preferred Shareholder with
respect to Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
<PAGE>   9
 
     Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Internal Revenue
Service Form W-8 (a "Form W-8"), signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A Form W-8 can be obtained from the
Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
     If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the Preferred Shareholder.
Backup withholding is not an additional tax. Rather, the Federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of the tax withheld. If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
     To avoid backup withholding on payments that are made to a Preferred
Shareholder with respect to Shares purchased pursuant to the Offer, the
Preferred Shareholder is required to notify the Depositary of his or her correct
TIN by completing the Substitute Form W-9 attached hereto certifying that the
TIN provided on Substitute Form W-9 is correct and that (a) the Preferred
Shareholder has not been notified by the Internal Revenue Service that he or she
is subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (b) the Internal Revenue Service has
notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed Form W-8 in order to avoid the applicable backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Preferred Shareholder is required to give the Depositary the social
security number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

                              FORMING PART OF THE
                       TERMS AND CONDITIONS OF THE OFFER

member of a registered national securities exchange or the National Association
of Securities Dealers, Inc., or by a commercial bank or trust company having an
office or correspondent in the United States which is a participant in an
approved Medallion Signature Guarantee Program (each of the foregoing being
referred to as an "Eligible Institution"). Signatures on this Letter of
Transmittal need not be guaranteed (a) if this Letter of Transmittal is signed
by the registered holder(s) of the Shares (which term, for purposes of this
document, shall include any participant in one of the Book-Entry Transfer
Facilities whose name appears on a security position listing as the owner of
Shares) tendered herewith and such holder(s) has not completed the box above
under the heading "Special Payment Instructions" or the box above under the
heading "Special Delivery Instructions" on this Letter of Transmittal, or (b) if
such Shares are tendered for the account of an Eligible Institution. See
Instruction 5.
 
     2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used if (a) certificates are to be forwarded herewith or,
(b) delivery of Shares is to be made by book-entry transfer pursuant to the
procedures set forth under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement. Certificates for
all physically delivered Shares, or a confirmation of a book-entry transfer into
the Depositary's account at one of the Book-Entry Transfer Facilities of all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal, and any other documents required by this Letter
of Transmittal, must be received by the Depositary at one of its addresses set
forth on the front page of this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase and Proxy Statement) with
respect to all Shares. Preferred Shareholders who wish to tender their Shares
yet who cannot deliver their Shares and all other required documents to the
Depositary on or prior to the Expiration Date must tender their Shares pursuant
to the guaranteed delivery procedure set forth under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement. Pursuant to such procedure: (a) such tender must be made by or
through an Eligible Institution, (b) a properly completed and duly executed
Notice of Guaranteed Delivery in the form provided by AEP (with any required
signature guarantees) must be received by the Depositary on or prior to the
applicable Expiration Date and (c) the certificates for all physically delivered
Shares, or a confirmation of a book-entry transfer into the Depositary's account
at one of the Book-Entry Transfer Facilities of all Shares delivered
electronically, together with a properly completed and duly executed Letter of
Transmittal and any other documents required by this Letter of Transmittal must
be received by the Depositary by 5:00 p.m. (New York City time) within three New
York Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery, all as provided under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING PREFERRED SHAREHOLDER. IF CERTIFICATES FOR
SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer -- Number of Shares; Purchase Prices; Expiration Date;
Dividends" in the Offer to Purchase and Proxy Statement. By executing this
Letter of Transmittal, the tendering stockholder waives any right to receive any
notice of the acceptance for payment of the Shares.
 
     3.  VOTING.  WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES
PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S
AMENDED ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND
PROXY STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE
PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED
IN THE OFFER TO PURCHASE AND PROXY STATEMENT). In addition, Preferred
Shareholders have the right to vote for or against the Proposed Amendment
regardless of whether they tender their Shares by casting their vote and duly
executing the proxy enclosed herewith or by voting in person at the Special
Meeting. By executing a Notice of Guaranteed Delivery, a Preferred Shareholder
is deemed to have tendered the Shares described in such Notice of Guaranteed
Delivery and to have voted such Shares in accordance with the proxy returned
therewith, if any. If no vote is indicated on an otherwise properly executed
proxy, then all Shares in respect of such proxy will be voted in favor of the
Proposed Amendment. See "Proposed Amendment and Proxy Solicitation" in the Offer
to Purchase and Proxy Statement. The Offer is being sent to all persons in whose
names Shares are registered on the books of APCo on the Record Date (as defined
in the Offer to Purchase and Proxy Statement) and transferees thereof. Only a
record holder of Shares on the Record Date may vote in person or by proxy at the
Special Meeting. No record date is fixed for determining which persons are
permitted to tender Shares. Any person who is the beneficial owner but not the
record holder of Shares must arrange for the record transfer of such Shares
prior to tendering.
 
     4.  PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all the Shares represented by any
certificate delivered to the Depositary are to be tendered, fill in the number
of Shares that are to be tendered in the box above under the heading
"Description of Shares Tendered". In such case, a new certificate for the
remainder of the Shares represented by the old certificate will be sent to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
box above under the heading "Special Payment Instructions" or "Special Delivery
Instructions", as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.
<PAGE>   17
 
     5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND/OR NOTICE OF GUARANTEED
DELIVERY; STOCK POWERS AND ENDORSEMENTS.  If either this Letter of Transmittal
or the Notice of Guaranteed Delivery (together, the "Tender Documents") is
signed by the registered holder(s) of the Shares tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificates without alteration, enlargement or any change whatsoever.
 
     If any of the Shares tendered under either Tender Document is held of
record by two or more persons, all such persons must sign such Tender Document.
 
     If any of the Shares tendered under either Tender Document is registered in
different names or different certificates, it will be necessary to complete,
sign and submit as many separate applicable Tender Documents as there are
different registrations or certificates.
 
     If either Tender Document is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made to, or Shares
not tendered or not purchased are to be registered in the name of, any person
other than the registered holder(s). Signatures on any such certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
     If either Tender Document or any certificate or stock power is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
AEP of the authority of such person so to act must be submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, AEP
will pay or cause to be paid any stock transfer taxes with respect to the sale
and transfer of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price is to be made to, or Shares not tendered
or not purchased are to be registered in the name of, any person other than the
registered holder(s), or if tendered Shares are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s), such
other person or otherwise) payable on account of the transfer to such person
will be deducted from the purchase price unless satisfactory evidence of the
payment of such taxes, or exemption therefrom, is submitted. See "Terms of the
Offer -- Acceptance of Shares for Payment and Payment of Purchase Price and
Dividends" in the Offer to Purchase and Proxy Statement. EXCEPT AS PROVIDED IN
THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE
CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, and/or
any Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificate for Shares not tendered or not purchased are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to an address
other than that shown in the box above under the heading "Name(s) and
Address(es) of Registered Holder(s)", then the "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Preferred Shareholders tendering Shares by book-entry transfer will
have any Shares not accepted for payment returned by crediting the account
maintained by such Preferred Shareholder at the Book-Entry Transfer Facility
from which such transfer was made.
 
     8.  SUBSTITUTE FORM W-9 AND FORM W-8.  The tendering Preferred Shareholder
is required to provide the Depositary with either a correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided under
"Important Tax Information" below, or a properly completed Form W-8. Failure to
provide the information on either Substitute Form W-9 or Form W-8 may subject
the tendering Preferred Shareholder to a $50 penalty imposed by the Internal
Revenue Service and to 31% federal income tax backup withholding on the payment
of the purchase price for the Shares. The box in Part 2 of Substitute Form W-9
may be checked if the tendering Preferred Shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future. If the box in Part 2 is checked and the Depositary is not provided with
a TIN by the time of payment, the Depositary will withhold 31% on all payments
of the purchase price for the Shares thereafter until a TIN is provided to the
Depositary.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or
requests for assistance may be directed to the Information Agent or the Dealer
Managers at their respective telephone numbers and addresses listed below.
Requests for additional copies of the Offer to Purchase and Proxy Statement,
this Letter of Transmittal or other tender offer materials may be directed to
the Information Agent and such copies will be furnished promptly at AEP's
expense. Preferred Shareholders may also contact their local broker, dealer,
commercial bank or trust company for assistance concerning the Offer.
<PAGE>   18
 
     10. SOLICITED TENDERS.  AEP will pay a solicitation fee of $.50 per Share
for any Shares tendered, accepted for payment and paid pursuant to the Offer,
covered by the Letter of Transmittal which designates, under the heading
"Solicited Tenders", as having solicited and obtained the tender, the name of
(a) any broker or dealer in securities, including a Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the National Association of Securities Dealers, Inc. (the
"NASD"), (b) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in soliciting
tenders outside the United States to the same extent as though it were an NASD
member, or (c) any bank or trust company (each of which is referred to herein as
a "Soliciting Dealer"). No such fee shall be payable to a Soliciting Dealer with
respect to the tender of Shares by a holder unless the Letter of Transmittal
accompanying such tender designates such Soliciting Dealer. No such fee shall be
payable to a Soliciting Dealer in respect of Shares registered in the name of
such Soliciting Dealer unless such Shares are held by such Soliciting Dealer as
nominee and such Shares are being tendered for the benefit of one or more
beneficial owners identified on the Letter of Transmittal or on the Notice of
Solicited Tenders (included in the materials provided to brokers and dealers).
No such fee shall be payable to a Soliciting Dealer with respect to the tender
of Shares by the holder of record, for the benefit of the beneficial owner,
unless the beneficial owner has designated such Soliciting Dealer. If tendered
Shares are being delivered by book-entry transfer, the Soliciting Dealer must
return a Notice of Solicited Tenders to the Depositary within three business
days after expiration of the Offer to receive a solicitation fee. No such fee
shall be payable to a Soliciting Dealer if such Soliciting Dealer is required
for any reason to transfer the amount of such fee to a depositing holder (other
than itself). No such fee shall be paid to a Soliciting Dealer with respect to
Shares tendered for such Soliciting Dealer's own account. No broker, dealer,
bank, trust company or fiduciary shall be deemed to be the agent of AEP, the
Depositary, the Information Agent or the Dealer Managers for purposes of the
Offer.
 
     Soliciting Dealers will include any organizations described in clauses (a),
(b) or (c) above even when the activities of such organization in connection
with the Offer consist solely of forwarding to clients materials relating to the
Offer, including this Letter of Transmittal, and rendering Shares as directed by
beneficial owners thereof. No Soliciting Dealer is required to make any
recommendation to holders of Shares as to whether to tender or refrain from
tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     11. IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by AEP, in its sole discretion, and its
determination shall be final and binding. AEP reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the opinion
of AEP's counsel, be unlawful. AEP also reserves the absolute right to waive any
of the conditions to the Offer or any defect or irregularity in any tender of
Shares and AEP's interpretation of the terms and conditions of the Offer
(including these instructions) shall be final and binding. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as AEP shall determine. None of AEP, APCo, the Dealer Managers, the
Depositary, the Information Agent or any other person shall be under any duty to
give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured or
waived.
 
     12. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
1-800-649-2153. In addition, you should advise the Depositary of any
certificate(s) you have in your possession. You will need to complete an
Affidavit of Loss with respect to the lost certificate(s) (which will be
provided by the Depositary) and pay an indemnity bond premium fee. The tender of
Shares pursuant to this Letter of Transmittal will not be valid unless prior to
the Expiration Date: (a) such procedures have been completed and a replacement
certificate for the Shares has been delivered to the Depositary or (b) a Notice
of Guaranteed Delivery has been delivered to the Depositary. See Instruction 2.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL, DULY EXECUTED, TOGETHER WITH, IF
APPLICABLE, CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER, AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY, OR, IF APPLICABLE, THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO
THE APPLICABLE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
either such Preferred Shareholder's correct TIN on Substitute Form W-9 below or
a properly completed Form W-8. If such Preferred Shareholder is an individual,
the TIN is his or her social security number. For businesses and other entities,
the number is the federal employer identification number. If the Depositary is
not provided with the correct TIN or properly completed Form W-8, the Preferred
Shareholder may be subject to a $50 penalty imposed by the Internal Revenue
Code. In addition, payments that are made to such Preferred Shareholder with
respect to Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
<PAGE>   19
 
     Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Internal Revenue
Service Form W-8 (a "Form W-8"), signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A Form W-8 can be obtained from the
Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
     If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the Preferred Shareholder.
Backup withholding is not an additional tax. Rather, the Federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of the tax withheld. If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
     To avoid backup withholding on payments that are made to a Preferred
Shareholder with respect to Shares purchased pursuant to the Offer, the
Preferred Shareholder is required to notify the Depositary of his or her correct
TIN by completing the Substitute Form W-9 attached hereto certifying that the
TIN provided on Substitute Form W-9 is correct and that (a) the Preferred
Shareholder has not been notified by the Internal Revenue Service that he or she
is subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (b) the Internal Revenue Service has
notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed Form W-8 in order to avoid the applicable backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Preferred Shareholder is required to give the Depositary the social
security number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to American Electric Power Company, Inc., a
New York corporation ("AEP"), the shares in the amount set forth in the box
above designated "Description of Shares Tendered" pursuant to AEP's offer to
purchase any and all of the outstanding shares of the series of cumulative
preferred stock of Appalachian Power Company, a Virginia corporation, and direct
utility subsidiary of AEP ("APCo"), shown on the first page hereof as to which
this Letter of Transmittal is applicable (the "Shares") at the purchase price
per Share shown on the first page hereof plus accrued and unpaid dividends
thereon, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase and Proxy Statement, dated January 30, 1997
(the "Offer to Purchase and Proxy Statement"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which as to the Shares,
together with the Offer to Purchase and Proxy Statement, constitutes the
"Offer"). WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S AMENDED
ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND PROXY
STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE PROPOSED
AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED IN THE
OFFER TO PURCHASE AND PROXY STATEMENT). See "Proposed Amendment and Proxy
Solicitation", "Terms of the Offer -- Extension of Tender Period; Termination;
Amendments" and "Terms of the Offer -- Certain Conditions of the Offer" in the
Offer to Purchase and Proxy Statement.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Shares tendered herewith in accordance with the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the undersigned hereby
sells, assigns and transfers to, or upon the order of, AEP all right, title and
interest in and to all the Shares that are being tendered hereby and hereby
constitutes and appoints First Chicago Trust Company of New York (the
"Depositary") the true and lawful agent and attorney-in-fact of the undersigned
with respect to such Shares, with full power of substitution (such power of
attorney being an irrevocable power coupled with an interest), to (a) deliver
certificates for such Shares, or transfer ownership of such Shares on the
account books maintained by the Book-Entry Transfer Facility that holds such
Shares, together, in any such case, with all accompanying evidences of transfer
and authenticity, to or upon the order of AEP, (b) present such Shares for
registration and transfer on the books of APCo and (c) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares, all in
accordance with the terms of the Offer. The Depositary will act as agent for
tendering stockholders for the purpose of receiving payment from AEP and
transmitting payment to tendering stockholders.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and that, when and to the extent the same are accepted for
payment by AEP, AEP will acquire good, marketable and unencumbered title
thereto, free and clear of all liens, restrictions, charges, encumbrances,
conditional sales agreements or other obligations relating to the sale or
transfer thereof, and the same will not be subject to any adverse claims. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or AEP to be necessary or desirable to complete the
sale, assignment and transfer of the Shares tendered hereby.
 
     All authority herein conferred or agreed to be conferred shall not be
affected by, and shall survive the death, bankruptcy or incapacity of the
undersigned, and any obligations of the undersigned hereunder shall be binding
upon the heirs, legal representatives, successors, assigns, executors and
administrators of the undersigned. Except as stated in the Offer, this tender is
irrevocable.
 
     The undersigned understands that tenders of Shares pursuant to any one of
the procedures described under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement and in the
instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer, including the undersigned's representation and
warranty that (a) the undersigned has a net long position in the Shares being
tendered within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended, and (b) the tender of such Shares complies
with such Rule 14e-4. AEP's acceptance for payment of Shares tendered pursuant
to the Offer will constitute a binding agreement between the undersigned and AEP
upon the terms and subject to the conditions of the Offer.
 
     The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase and Proxy Statement, AEP may terminate or amend the Offer
or may not be required to purchase any of the Shares tendered hereby. In either
event, the undersigned understands that certificate(s) for any Shares not
tendered or not purchased will be returned to the undersigned.

designated above). Similarly, unless otherwise indicated in the box below under
the heading "Special Delivery Instructions", please mail the check for the
purchase price of any Shares purchased and/or any certificates for Shares not
tendered or not purchased (and accompanying documents, as appropriate) to the

registered holder(s) thereof if AEP does not accept for payment any of the
Shares so tendered.

                              FORMING PART OF THE
                       TERMS AND CONDITIONS OF THE OFFER
 
     1.  GUARANTEE OF SIGNATURES.  Except as otherwise provided below, all
signatures on this Letter of Transmittal must be guaranteed by a firm that is a
member of a registered national securities exchange or the National Association
of Securities Dealers, Inc., or by a commercial bank or trust company having an
office or correspondent in the United States which is a participant in an
approved Medallion Signature Guarantee Program (each of the foregoing being
referred to as an "Eligible Institution"). Signatures on this Letter of
Transmittal need not be guaranteed (a) if this Letter of Transmittal is signed
by the registered holder(s) of the Shares (which term, for purposes of this
document, shall include any participant in one of the Book-Entry Transfer
Facilities whose name appears on a security position listing as the owner of
Shares) tendered herewith and such holder(s) has not completed the box above
under the heading "Special Payment Instructions" or the box above under the
heading "Special Delivery Instructions" on this Letter of Transmittal, or (b) if
such Shares are tendered for the account of an Eligible Institution. See
Instruction 5.
 
     2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used if (a) certificates are to be forwarded herewith or,
(b) delivery of Shares is to be made by book-entry transfer pursuant to the
procedures set forth under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement. Certificates for
all physically delivered Shares, or a confirmation of a book-entry transfer into
the Depositary's account at one of the Book-Entry Transfer Facilities of all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal, and any other documents required by this Letter
of Transmittal, must be received by the Depositary at one of its addresses set
forth on the front page of this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase and Proxy Statement) with
respect to all Shares. Preferred Shareholders who wish to tender their Shares
yet who cannot deliver their Shares and all other required documents to the
Depositary on or prior to the Expiration Date must tender their Shares pursuant
to the guaranteed delivery procedure set forth under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement. Pursuant to such procedure: (a) such tender must be made by or
through an Eligible Institution, (b) a properly completed and duly executed
Notice of Guaranteed Delivery in the form provided by AEP (with any required
signature guarantees) must be received by the Depositary on or prior to the
applicable Expiration Date and (c) the certificates for all physically delivered
Shares, or a confirmation of a book-entry transfer into the Depositary's account
at one of the Book-Entry Transfer Facilities of all Shares delivered
electronically, together with a properly completed and duly executed Letter of
Transmittal and any other documents required by this Letter of Transmittal must
be received by the Depositary by 5:00 p.m. (New York City time) within three New
York Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery, all as provided under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING PREFERRED SHAREHOLDER. IF CERTIFICATES FOR
SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer -- Number of Shares; Purchase Prices; Expiration Date;
Dividends" in the Offer to Purchase and Proxy Statement. By executing this
Letter of Transmittal, the tendering stockholder waives any right to receive any
notice of the acceptance for payment of the Shares.
 
     3.  VOTING.  WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES
PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S
AMENDED ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND
PROXY STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE
PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED
IN THE OFFER TO PURCHASE AND PROXY STATEMENT). In addition, Preferred
Shareholders have the right to vote for or against the Proposed Amendment
regardless of whether they tender their Shares by casting their vote and duly
executing the proxy enclosed herewith or by voting in person at the Special
Meeting. By executing a Notice of Guaranteed Delivery, a Preferred Shareholder
is deemed to have tendered the Shares described in such Notice of Guaranteed
Delivery and to have voted such Shares in accordance with the proxy returned
therewith, if any. If no vote is indicated on an otherwise properly executed
proxy, then all Shares in respect of such proxy will be voted in favor of the
Proposed Amendment. See "Proposed Amendment and Proxy Solicitation" in the Offer
to Purchase and Proxy Statement. The Offer is being sent to all persons in whose
names Shares are registered on the books of APCo on the Record Date (as defined
in the Offer to Purchase and Proxy Statement) and transferees thereof. Only a
record holder of Shares on the Record Date may vote in person or by proxy at the
Special Meeting. No record date is fixed for determining which persons are
permitted to tender Shares. Any person who is the beneficial owner but not the
record holder of Shares must arrange for the record transfer of such Shares
prior to tendering.
 
     4.  PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all the Shares represented by any
certificate delivered to the Depositary are to be tendered, fill in the number
of Shares that are to be tendered in the box above under the heading
"Description of Shares Tendered". In such case, a new certificate for the
remainder of the Shares represented by the old certificate will be sent to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
box above under the heading "Special Payment Instructions" or "Special Delivery
Instructions", as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.
<PAGE>   27
 
     5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND/OR NOTICE OF GUARANTEED
DELIVERY; STOCK POWERS AND ENDORSEMENTS.  If either this Letter of Transmittal
or the Notice of Guaranteed Delivery (together, the "Tender Documents") is
signed by the registered holder(s) of the Shares tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificates without alteration, enlargement or any change whatsoever.
 
     If any of the Shares tendered under either Tender Document is held of
record by two or more persons, all such persons must sign such Tender Document.
 
     If any of the Shares tendered under either Tender Document is registered in
different names or different certificates, it will be necessary to complete,
sign and submit as many separate applicable Tender Documents as there are
different registrations or certificates.
 
     If either Tender Document is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made to, or Shares
not tendered or not purchased are to be registered in the name of, any person
other than the registered holder(s). Signatures on any such certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
     If either Tender Document or any certificate or stock power is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
AEP of the authority of such person so to act must be submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, AEP
will pay or cause to be paid any stock transfer taxes with respect to the sale
and transfer of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price is to be made to, or Shares not tendered
or not purchased are to be registered in the name of, any person other than the
registered holder(s), or if tendered Shares are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s), such
other person or otherwise) payable on account of the transfer to such person
will be deducted from the purchase price unless satisfactory evidence of the
payment of such taxes, or exemption therefrom, is submitted. See "Terms of the
Offer -- Acceptance of Shares for Payment and Payment of Purchase Price and
Dividends" in the Offer to Purchase and Proxy Statement. EXCEPT AS PROVIDED IN
THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE
CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, and/or
any Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificate for Shares not tendered or not purchased are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to an address
other than that shown in the box above under the heading "Name(s) and
Address(es) of Registered Holder(s)", then the "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Preferred Shareholders tendering Shares by book-entry transfer will
have any Shares not accepted for payment returned by crediting the account
maintained by such Preferred Shareholder at the Book-Entry Transfer Facility
from which such transfer was made.
 
     8.  SUBSTITUTE FORM W-9 AND FORM W-8.  The tendering Preferred Shareholder
is required to provide the Depositary with either a correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided under
"Important Tax Information" below, or a properly completed Form W-8. Failure to
provide the information on either Substitute Form W-9 or Form W-8 may subject
the tendering Preferred Shareholder to a $50 penalty imposed by the Internal
Revenue Service and to 31% federal income tax backup withholding on the payment
of the purchase price for the Shares. The box in Part 2 of Substitute Form W-9
may be checked if the tendering Preferred Shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future. If the box in Part 2 is checked and the Depositary is not provided with
a TIN by the time of payment, the Depositary will withhold 31% on all payments
of the purchase price for the Shares thereafter until a TIN is provided to the
Depositary.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or
requests for assistance may be directed to the Information Agent or the Dealer
Managers at their respective telephone numbers and addresses listed below.
Requests for additional copies of the Offer to Purchase and Proxy Statement,
this Letter of Transmittal or other tender offer materials may be directed to
the Information Agent and such copies will be furnished promptly at AEP's
expense. Preferred Shareholders may also contact their local broker, dealer,
commercial bank or trust company for assistance concerning the Offer.
<PAGE>   28
 
     10. SOLICITED TENDERS.  AEP will pay a solicitation fee of $.50 per Share
for any Shares tendered, accepted for payment and paid pursuant to the Offer,
covered by the Letter of Transmittal which designates, under the heading
"Solicited Tenders", as having solicited and obtained the tender, the name of
(a) any broker or dealer in securities, including a Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the National Association of Securities Dealers, Inc. (the
"NASD"), (b) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in soliciting
tenders outside the United States to the same extent as though it were an NASD
member, or (c) any bank or trust company (each of which is referred to herein as
a "Soliciting Dealer"). No such fee shall be payable to a Soliciting Dealer with
respect to the tender of Shares by a holder unless the Letter of Transmittal
accompanying such tender designates such Soliciting Dealer. No such fee shall be
payable to a Soliciting Dealer in respect of Shares registered in the name of
such Soliciting Dealer unless such Shares are held by such Soliciting Dealer as
nominee and such Shares are being tendered for the benefit of one or more
beneficial owners identified on the Letter of Transmittal or on the Notice of
Solicited Tenders (included in the materials provided to brokers and dealers).
No such fee shall be payable to a Soliciting Dealer with respect to the tender
of Shares by the holder of record, for the benefit of the beneficial owner,
unless the beneficial owner has designated such Soliciting Dealer. If tendered
Shares are being delivered by book-entry transfer, the Soliciting Dealer must
return a Notice of Solicited Tenders to the Depositary within three business
days after expiration of the Offer to receive a solicitation fee. No such fee
shall be payable to a Soliciting Dealer if such Soliciting Dealer is required
for any reason to transfer the amount of such fee to a depositing holder (other
than itself). No such fee shall be paid to a Soliciting Dealer with respect to
Shares tendered for such Soliciting Dealer's own account. No broker, dealer,
bank, trust company or fiduciary shall be deemed to be the agent of AEP, the
Depositary, the Information Agent or the Dealer Managers for purposes of the
Offer.
 
     Soliciting Dealers will include any organizations described in clauses (a),
(b) or (c) above even when the activities of such organization in connection
with the Offer consist solely of forwarding to clients materials relating to the
Offer, including this Letter of Transmittal, and rendering Shares as directed by
beneficial owners thereof. No Soliciting Dealer is required to make any
recommendation to holders of Shares as to whether to tender or refrain from
tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     11. IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by AEP, in its sole discretion, and its
determination shall be final and binding. AEP reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the opinion
of AEP's counsel, be unlawful. AEP also reserves the absolute right to waive any
of the conditions to the Offer or any defect or irregularity in any tender of
Shares and AEP's interpretation of the terms and conditions of the Offer
(including these instructions) shall be final and binding. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as AEP shall determine. None of AEP, APCo, the Dealer Managers, the
Depositary, the Information Agent or any other person shall be under any duty to
give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured or
waived.
 
     12. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
1-800-649-2153. In addition, you should advise the Depositary of any
certificate(s) you have in your possession. You will need to complete an
Affidavit of Loss with respect to the lost certificate(s) (which will be
provided by the Depositary) and pay an indemnity bond premium fee. The tender of
Shares pursuant to this Letter of Transmittal will not be valid unless prior to
the Expiration Date: (a) such procedures have been completed and a replacement
certificate for the Shares has been delivered to the Depositary or (b) a Notice
of Guaranteed Delivery has been delivered to the Depositary. See Instruction 2.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL, DULY EXECUTED, TOGETHER WITH, IF
APPLICABLE, CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER, AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY, OR, IF APPLICABLE, THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO
THE APPLICABLE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
either such Preferred Shareholder's correct TIN on Substitute Form W-9 below or
a properly completed Form W-8. If such Preferred Shareholder is an individual,
the TIN is his or her social security number. For businesses and other entities,
the number is the federal employer identification number. If the Depositary is
not provided with the correct TIN or properly completed Form W-8, the Preferred
Shareholder may be subject to a $50 penalty imposed by the Internal Revenue
Code. In addition, payments that are made to such Preferred Shareholder with
respect to Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
<PAGE>   29
 
     Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Internal Revenue
Service Form W-8 (a "Form W-8"), signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A Form W-8 can be obtained from the
Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
     If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the Preferred Shareholder.
Backup withholding is not an additional tax. Rather, the Federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of the tax withheld. If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
     To avoid backup withholding on payments that are made to a Preferred
Shareholder with respect to Shares purchased pursuant to the Offer, the
Preferred Shareholder is required to notify the Depositary of his or her correct
TIN by completing the Substitute Form W-9 attached hereto certifying that the
TIN provided on Substitute Form W-9 is correct and that (a) the Preferred
Shareholder has not been notified by the Internal Revenue Service that he or she
is subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (b) the Internal Revenue Service has
notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed Form W-8 in order to avoid the applicable backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Preferred Shareholder is required to give the Depositary the social
security number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to American Electric Power Company, Inc., a
New York corporation ("AEP"), the shares in the amount set forth in the box
above designated "Description of Shares Tendered" pursuant to AEP's offer to
purchase any and all of the outstanding shares of the series of cumulative

this Letter of Transmittal is applicable (the "Shares") at the purchase price
per Share shown on the first page hereof plus accrued and unpaid dividends
thereon, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase and Proxy Statement, dated January 30, 1997
(the "Offer to Purchase and Proxy Statement"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which as to the Shares,
together with the Offer to Purchase and Proxy Statement, constitutes the
"Offer"). WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S AMENDED
ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND PROXY
STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE PROPOSED
AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED IN THE
OFFER TO PURCHASE AND PROXY STATEMENT). See "Proposed Amendment and Proxy
Solicitation", "Terms of the Offer -- Extension of Tender Period; Termination;
Amendments" and "Terms of the Offer -- Certain Conditions of the Offer" in the
Offer to Purchase and Proxy Statement.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Shares tendered herewith in accordance with the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the undersigned hereby
sells, assigns and transfers to, or upon the order of, AEP all right, title and
interest in and to all the Shares that are being tendered hereby and hereby
constitutes and appoints First Chicago Trust Company of New York (the
"Depositary") the true and lawful agent and attorney-in-fact of the undersigned
with respect to such Shares, with full power of substitution (such power of
attorney being an irrevocable power coupled with an interest), to (a) deliver
certificates for such Shares, or transfer ownership of such Shares on the
account books maintained by the Book-Entry Transfer Facility that holds such
Shares, together, in any such case, with all accompanying evidences of transfer
and authenticity, to or upon the order of AEP, (b) present such Shares for
registration and transfer on the books of APCo and (c) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares, all in
accordance with the terms of the Offer. The Depositary will act as agent for
tendering stockholders for the purpose of receiving payment from AEP and
transmitting payment to tendering stockholders.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and that, when and to the extent the same are accepted for
payment by AEP, AEP will acquire good, marketable and unencumbered title
thereto, free and clear of all liens, restrictions, charges, encumbrances,
conditional sales agreements or other obligations relating to the sale or
transfer thereof, and the same will not be subject to any adverse claims. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or AEP to be necessary or desirable to complete the
sale, assignment and transfer of the Shares tendered hereby.
 
     All authority herein conferred or agreed to be conferred shall not be
affected by, and shall survive the death, bankruptcy or incapacity of the
undersigned, and any obligations of the undersigned hereunder shall be binding
upon the heirs, legal representatives, successors, assigns, executors and
administrators of the undersigned. Except as stated in the Offer, this tender is
irrevocable.
 
     The undersigned understands that tenders of Shares pursuant to any one of
the procedures described under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement and in the
instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer, including the undersigned's representation and
warranty that (a) the undersigned has a net long position in the Shares being
tendered within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended, and (b) the tender of such Shares complies
with such Rule 14e-4. AEP's acceptance for payment of Shares tendered pursuant
to the Offer will constitute a binding agreement between the undersigned and AEP
upon the terms and subject to the conditions of the Offer.
 
     The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase and Proxy Statement, AEP may terminate or amend the Offer
or may not be required to purchase any of the Shares tendered hereby. In either
event, the undersigned understands that certificate(s) for any Shares not
tendered or not purchased will be returned to the undersigned.

the heading "Special Delivery Instructions", please mail the check for the

referred to as an "Eligible Institution"). Signatures on this Letter of
Transmittal need not be guaranteed (a) if this Letter of Transmittal is signed
by the registered holder(s) of the Shares (which term, for purposes of this
document, shall include any participant in one of the Book-Entry Transfer
Facilities whose name appears on a security position listing as the owner of
Shares) tendered herewith and such holder(s) has not completed the box above
under the heading "Special Payment Instructions" or the box above under the
heading "Special Delivery Instructions" on this Letter of Transmittal, or (b) if
such Shares are tendered for the account of an Eligible Institution. See
Instruction 5.
 
     2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used if (a) certificates are to be forwarded herewith or,
(b) delivery of Shares is to be made by book-entry transfer pursuant to the
procedures set forth under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement. Certificates for
all physically delivered Shares, or a confirmation of a book-entry transfer into
the Depositary's account at one of the Book-Entry Transfer Facilities of all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal, and any other documents required by this Letter
of Transmittal, must be received by the Depositary at one of its addresses set
forth on the front page of this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase and Proxy Statement) with
respect to all Shares. Preferred Shareholders who wish to tender their Shares
yet who cannot deliver their Shares and all other required documents to the
Depositary on or prior to the Expiration Date must tender their Shares pursuant
to the guaranteed delivery procedure set forth under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement. Pursuant to such procedure: (a) such tender must be made by or
through an Eligible Institution, (b) a properly completed and duly executed
Notice of Guaranteed Delivery in the form provided by AEP (with any required
signature guarantees) must be received by the Depositary on or prior to the
applicable Expiration Date and (c) the certificates for all physically delivered
Shares, or a confirmation of a book-entry transfer into the Depositary's account
at one of the Book-Entry Transfer Facilities of all Shares delivered
electronically, together with a properly completed and duly executed Letter of
Transmittal and any other documents required by this Letter of Transmittal must
be received by the Depositary by 5:00 p.m. (New York City time) within three New
York Stock Exchange trading days after the date of execution of such Notice of
Guaranteed Delivery, all as provided under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE TENDERING PREFERRED SHAREHOLDER. IF CERTIFICATES FOR
SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer -- Number of Shares; Purchase Prices; Expiration Date;
Dividends" in the Offer to Purchase and Proxy Statement. By executing this
Letter of Transmittal, the tendering stockholder waives any right to receive any
notice of the acceptance for payment of the Shares.
 
     3.  VOTING.  WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES
PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S
AMENDED ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND
PROXY STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE
PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED
IN THE OFFER TO PURCHASE AND PROXY STATEMENT). In addition, Preferred
Shareholders have the right to vote for or against the Proposed Amendment
regardless of whether they tender their Shares by casting their vote and duly
executing the proxy enclosed herewith or by voting in person at the Special
Meeting. By executing a Notice of Guaranteed Delivery, a Preferred Shareholder
is deemed to have tendered the Shares described in such Notice of Guaranteed
Delivery and to have voted such Shares in accordance with the proxy returned
therewith, if any. If no vote is indicated on an otherwise properly executed
proxy, then all Shares in respect of such proxy will be voted in favor of the
Proposed Amendment. See "Proposed Amendment and Proxy Solicitation" in the Offer
to Purchase and Proxy Statement. The Offer is being sent to all persons in whose
names Shares are registered on the books of APCo on the Record Date (as defined
in the Offer to Purchase and Proxy Statement) and transferees thereof. Only a
record holder of Shares on the Record Date may vote in person or by proxy at the
Special Meeting. No record date is fixed for determining which persons are
permitted to tender Shares. Any person who is the beneficial owner but not the
record holder of Shares must arrange for the record transfer of such Shares
prior to tendering.
 
     4.  PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all the Shares represented by any
certificate delivered to the Depositary are to be tendered, fill in the number
of Shares that are to be tendered in the box above under the heading
"Description of Shares Tendered". In such case, a new certificate for the
remainder of the Shares represented by the old certificate will be sent to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
box above under the heading "Special Payment Instructions" or "Special Delivery
Instructions", as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.

     5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND/OR NOTICE OF GUARANTEED
DELIVERY; STOCK POWERS AND ENDORSEMENTS.  If either this Letter of Transmittal
or the Notice of Guaranteed Delivery (together, the "Tender Documents") is
signed by the registered holder(s) of the Shares tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificates without alteration, enlargement or any change whatsoever.
 
     If any of the Shares tendered under either Tender Document is held of
record by two or more persons, all such persons must sign such Tender Document.
 
     If any of the Shares tendered under either Tender Document is registered in
different names or different certificates, it will be necessary to complete,
sign and submit as many separate applicable Tender Documents as there are
different registrations or certificates.
 
     If either Tender Document is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made to, or Shares
not tendered or not purchased are to be registered in the name of, any person
other than the registered holder(s). Signatures on any such certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
     If either Tender Document or any certificate or stock power is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
AEP of the authority of such person so to act must be submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, AEP
will pay or cause to be paid any stock transfer taxes with respect to the sale
and transfer of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price is to be made to, or Shares not tendered
or not purchased are to be registered in the name of, any person other than the
registered holder(s), or if tendered Shares are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s), such
other person or otherwise) payable on account of the transfer to such person
will be deducted from the purchase price unless satisfactory evidence of the
payment of such taxes, or exemption therefrom, is submitted. See "Terms of the
Offer -- Acceptance of Shares for Payment and Payment of Purchase Price and
Dividends" in the Offer to Purchase and Proxy Statement. EXCEPT AS PROVIDED IN
THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE
CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, and/or
any Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificate for Shares not tendered or not purchased are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to an address
other than that shown in the box above under the heading "Name(s) and
Address(es) of Registered Holder(s)", then the "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Preferred Shareholders tendering Shares by book-entry transfer will
have any Shares not accepted for payment returned by crediting the account
maintained by such Preferred Shareholder at the Book-Entry Transfer Facility
from which such transfer was made.
 
     8.  SUBSTITUTE FORM W-9 AND FORM W-8.  The tendering Preferred Shareholder
is required to provide the Depositary with either a correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided under
"Important Tax Information" below, or a properly completed Form W-8. Failure to
provide the information on either Substitute Form W-9 or Form W-8 may subject
the tendering Preferred Shareholder to a $50 penalty imposed by the Internal
Revenue Service and to 31% federal income tax backup withholding on the payment
of the purchase price for the Shares. The box in Part 2 of Substitute Form W-9
may be checked if the tendering Preferred Shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future. If the box in Part 2 is checked and the Depositary is not provided with
a TIN by the time of payment, the Depositary will withhold 31% on all payments
of the purchase price for the Shares thereafter until a TIN is provided to the
Depositary.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or
requests for assistance may be directed to the Information Agent or the Dealer
Managers at their respective telephone numbers and addresses listed below.
Requests for additional copies of the Offer to Purchase and Proxy Statement,
this Letter of Transmittal or other tender offer materials may be directed to
the Information Agent and such copies will be furnished promptly at AEP's
expense. Preferred Shareholders may also contact their local broker, dealer,
commercial bank or trust company for assistance concerning the Offer.
<PAGE>   38
 
     10. SOLICITED TENDERS.  AEP will pay a solicitation fee of $.50 per Share
for any Shares tendered, accepted for payment and paid pursuant to the Offer,
covered by the Letter of Transmittal which designates, under the heading
"Solicited Tenders", as having solicited and obtained the tender, the name of
(a) any broker or dealer in securities, including a Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the National Association of Securities Dealers, Inc. (the
"NASD"), (b) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in soliciting
tenders outside the United States to the same extent as though it were an NASD
member, or (c) any bank or trust company (each of which is referred to herein as
a "Soliciting Dealer"). No such fee shall be payable to a Soliciting Dealer with
respect to the tender of Shares by a holder unless the Letter of Transmittal
accompanying such tender designates such Soliciting Dealer. No such fee shall be
payable to a Soliciting Dealer in respect of Shares registered in the name of
such Soliciting Dealer unless such Shares are held by such Soliciting Dealer as
nominee and such Shares are being tendered for the benefit of one or more
beneficial owners identified on the Letter of Transmittal or on the Notice of
Solicited Tenders (included in the materials provided to brokers and dealers).
No such fee shall be payable to a Soliciting Dealer with respect to the tender
of Shares by the holder of record, for the benefit of the beneficial owner,
unless the beneficial owner has designated such Soliciting Dealer. If tendered
Shares are being delivered by book-entry transfer, the Soliciting Dealer must
return a Notice of Solicited Tenders to the Depositary within three business
days after expiration of the Offer to receive a solicitation fee. No such fee
shall be payable to a Soliciting Dealer if such Soliciting Dealer is required
for any reason to transfer the amount of such fee to a depositing holder (other
than itself). No such fee shall be paid to a Soliciting Dealer with respect to
Shares tendered for such Soliciting Dealer's own account. No broker, dealer,
bank, trust company or fiduciary shall be deemed to be the agent of AEP, the
Depositary, the Information Agent or the Dealer Managers for purposes of the
Offer.
 
     Soliciting Dealers will include any organizations described in clauses (a),
(b) or (c) above even when the activities of such organization in connection
with the Offer consist solely of forwarding to clients materials relating to the
Offer, including this Letter of Transmittal, and rendering Shares as directed by
beneficial owners thereof. No Soliciting Dealer is required to make any
recommendation to holders of Shares as to whether to tender or refrain from
tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     11. IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by AEP, in its sole discretion, and its
determination shall be final and binding. AEP reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the opinion
of AEP's counsel, be unlawful. AEP also reserves the absolute right to waive any
of the conditions to the Offer or any defect or irregularity in any tender of
Shares and AEP's interpretation of the terms and conditions of the Offer
(including these instructions) shall be final and binding. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as AEP shall determine. None of AEP, APCo, the Dealer Managers, the
Depositary, the Information Agent or any other person shall be under any duty to
give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured or
waived.
 
     12. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
1-800-649-2153. In addition, you should advise the Depositary of any
certificate(s) you have in your possession. You will need to complete an
Affidavit of Loss with respect to the lost certificate(s) (which will be
provided by the Depositary) and pay an indemnity bond premium fee. The tender of
Shares pursuant to this Letter of Transmittal will not be valid unless prior to
the Expiration Date: (a) such procedures have been completed and a replacement
certificate for the Shares has been delivered to the Depositary or (b) a Notice
of Guaranteed Delivery has been delivered to the Depositary. See Instruction 2.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL, DULY EXECUTED, TOGETHER WITH, IF
APPLICABLE, CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER, AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY, OR, IF APPLICABLE, THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO
THE APPLICABLE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
either such Preferred Shareholder's correct TIN on Substitute Form W-9 below or
a properly completed Form W-8. If such Preferred Shareholder is an individual,
the TIN is his or her social security number. For businesses and other entities,
the number is the federal employer identification number. If the Depositary is
not provided with the correct TIN or properly completed Form W-8, the Preferred
Shareholder may be subject to a $50 penalty imposed by the Internal Revenue
Code. In addition, payments that are made to such Preferred Shareholder with
respect to Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
<PAGE>   39
 
     Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Internal Revenue
Service Form W-8 (a "Form W-8"), signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A Form W-8 can be obtained from the
Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
     If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the Preferred Shareholder.
Backup withholding is not an additional tax. Rather, the Federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of the tax withheld. If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
     To avoid backup withholding on payments that are made to a Preferred
Shareholder with respect to Shares purchased pursuant to the Offer, the
Preferred Shareholder is required to notify the Depositary of his or her correct
TIN by completing the Substitute Form W-9 attached hereto certifying that the
TIN provided on Substitute Form W-9 is correct and that (a) the Preferred
Shareholder has not been notified by the Internal Revenue Service that he or she
is subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (b) the Internal Revenue Service has
notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed Form W-8 in order to avoid the applicable backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Preferred Shareholder is required to give the Depositary the social
security number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

Ladies and Gentlemen:
 
     The undersigned hereby tenders to American Electric Power Company, Inc., a
New York corporation ("AEP"), the shares in the amount set forth in the box
above designated "Description of Shares Tendered" pursuant to AEP's offer to
purchase any and all of the outstanding shares of the series of cumulative
preferred stock of Appalachian Power Company, a Virginia corporation, and direct
utility subsidiary of AEP ("APCo"), shown on the first page hereof as to which
this Letter of Transmittal is applicable (the "Shares") at the purchase price
per Share shown on the first page hereof plus accrued and unpaid dividends
thereon, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase and Proxy Statement, dated January 30, 1997
(the "Offer to Purchase and Proxy Statement"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which as to the Shares,
together with the Offer to Purchase and Proxy Statement, constitutes the
"Offer"). WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S AMENDED
ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND PROXY
STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE PROPOSED
AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED IN THE
OFFER TO PURCHASE AND PROXY STATEMENT). See "Proposed Amendment and Proxy
Solicitation", "Terms of the Offer -- Extension of Tender Period; Termination;
Amendments" and "Terms of the Offer -- Certain Conditions of the Offer" in the
Offer to Purchase and Proxy Statement.
 
     Subject to, and effective upon, acceptance for payment of and payment for
the Shares tendered herewith in accordance with the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the undersigned hereby
sells, assigns and transfers to, or upon the order of, AEP all right, title and
interest in and to all the Shares that are being tendered hereby and hereby
constitutes and appoints First Chicago Trust Company of New York (the
"Depositary") the true and lawful agent and attorney-in-fact of the undersigned
with respect to such Shares, with full power of substitution (such power of
attorney being an irrevocable power coupled with an interest), to (a) deliver
certificates for such Shares, or transfer ownership of such Shares on the
account books maintained by the Book-Entry Transfer Facility that holds such
Shares, together, in any such case, with all accompanying evidences of transfer
and authenticity, to or upon the order of AEP, (b) present such Shares for
registration and transfer on the books of APCo and (c) receive all benefits and
otherwise exercise all rights of beneficial ownership of such Shares, all in
accordance with the terms of the Offer. The Depositary will act as agent for
tendering stockholders for the purpose of receiving payment from AEP and
transmitting payment to tendering stockholders.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and that, when and to the extent the same are accepted for
payment by AEP, AEP will acquire good, marketable and unencumbered title
thereto, free and clear of all liens, restrictions, charges, encumbrances,
conditional sales agreements or other obligations relating to the sale or
transfer thereof, and the same will not be subject to any adverse claims. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Depositary or AEP to be necessary or desirable to complete the
sale, assignment and transfer of the Shares tendered hereby.
 
     All authority herein conferred or agreed to be conferred shall not be
affected by, and shall survive the death, bankruptcy or incapacity of the
undersigned, and any obligations of the undersigned hereunder shall be binding
upon the heirs, legal representatives, successors, assigns, executors and
administrators of the undersigned. Except as stated in the Offer, this tender is
irrevocable.
 
     The undersigned understands that tenders of Shares pursuant to any one of
the procedures described under the heading "Terms of the Offer -- Procedure for
Tendering Shares" in the Offer to Purchase and Proxy Statement and in the
instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer, including the undersigned's representation and
warranty that (a) the undersigned has a net long position in the Shares being
tendered within the meaning of Rule 14e-4 promulgated under the Securities
Exchange Act of 1934, as amended, and (b) the tender of such Shares complies
with such Rule 14e-4. AEP's acceptance for payment of Shares tendered pursuant
to the Offer will constitute a binding agreement between the undersigned and AEP
upon the terms and subject to the conditions of the Offer.
 
     The undersigned recognizes that, under certain circumstances set forth in
the Offer to Purchase and Proxy Statement, AEP may terminate or amend the Offer
or may not be required to purchase any of the Shares tendered hereby. In either
event, the undersigned understands that certificate(s) for any Shares not
tendered or not purchased will be returned to the undersigned.

Payment Instructions", please issue the check for the purchase price of any
Shares purchased, and/or return any Shares not tendered or not purchased, in the

designated above). Similarly, unless otherwise indicated in the box below under
the heading "Special Delivery Instructions", please mail the check for the
purchase price of any Shares purchased and/or any certificates for Shares not
tendered or not purchased (and accompanying documents, as appropriate) to the

Instructions" are completed, please issue the check for the purchase price of
any Shares purchased and/or return any Shares not tendered or not purchased in
the name(s) of, and mail said check and/or any certificates to, the person(s) so

registered holder(s) thereof if AEP does not accept for payment any of the
Shares so tendered.

by the registered holder(s) of the Shares (which term, for purposes of this

under the heading "Special Payment Instructions" or the box above under the
heading "Special Delivery Instructions" on this Letter of Transmittal, or (b) if
such Shares are tendered for the account of an Eligible Institution. See
Instruction 5.
 
     2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used if (a) certificates are to be forwarded herewith or,
(b) delivery of Shares is to be made by book-entry transfer pursuant to the

all physically delivered Shares, or a confirmation of a book-entry transfer into
the Depositary's account at one of the Book-Entry Transfer Facilities of all
Shares delivered electronically, as well as a properly completed and duly
executed Letter of Transmittal, and any other documents required by this Letter
of Transmittal, must be received by the Depositary at one of its addresses set
forth on the front page of this Letter of Transmittal on or prior to the
Expiration Date (as defined in the Offer to Purchase and Proxy Statement) with
respect to all Shares. Preferred Shareholders who wish to tender their Shares
yet who cannot deliver their Shares and all other required documents to the
Depositary on or prior to the Expiration Date must tender their Shares pursuant
to the guaranteed delivery procedure set forth under the heading "Terms of the
Offer -- Procedure for Tendering Shares" in the Offer to Purchase and Proxy
Statement. Pursuant to such procedure: (a) such tender must be made by or
through an Eligible Institution, (b) a properly completed and duly executed
Notice of Guaranteed Delivery in the form provided by AEP (with any required
signature guarantees) must be received by the Depositary on or prior to the

Statement.
 
     THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE

SHARES ARE SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED.
 
     No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer -- Number of Shares; Purchase Prices; Expiration Date;
Dividends" in the Offer to Purchase and Proxy Statement. By executing this
Letter of Transmittal, the tendering stockholder waives any right to receive any
notice of the acceptance for payment of the Shares.
 
     3.  VOTING.  WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES
PURSUANT TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S
AMENDED ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND
PROXY STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE
PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED
IN THE OFFER TO PURCHASE AND PROXY STATEMENT). In addition, Preferred
Shareholders have the right to vote for or against the Proposed Amendment
regardless of whether they tender their Shares by casting their vote and duly
executing the proxy enclosed herewith or by voting in person at the Special
Meeting. By executing a Notice of Guaranteed Delivery, a Preferred Shareholder
is deemed to have tendered the Shares described in such Notice of Guaranteed
Delivery and to have voted such Shares in accordance with the proxy returned
therewith, if any. If no vote is indicated on an otherwise properly executed
proxy, then all Shares in respect of such proxy will be voted in favor of the
Proposed Amendment. See "Proposed Amendment and Proxy Solicitation" in the Offer
to Purchase and Proxy Statement. The Offer is being sent to all persons in whose
names Shares are registered on the books of APCo on the Record Date (as defined
in the Offer to Purchase and Proxy Statement) and transferees thereof. Only a
record holder of Shares on the Record Date may vote in person or by proxy at the
Special Meeting. No record date is fixed for determining which persons are
permitted to tender Shares. Any person who is the beneficial owner but not the
record holder of Shares must arrange for the record transfer of such Shares
prior to tendering.
 
     4.  PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all the Shares represented by any
certificate delivered to the Depositary are to be tendered, fill in the number
of Shares that are to be tendered in the box above under the heading
"Description of Shares Tendered". In such case, a new certificate for the
remainder of the Shares represented by the old certificate will be sent to the
person(s) signing this Letter of Transmittal, unless otherwise provided in the
box above under the heading "Special Payment Instructions" or "Special Delivery
Instructions", as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.

     5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND/OR NOTICE OF GUARANTEED
DELIVERY; STOCK POWERS AND ENDORSEMENTS.  If either this Letter of Transmittal
or the Notice of Guaranteed Delivery (together, the "Tender Documents") is
signed by the registered holder(s) of the Shares tendered hereby, the
signature(s) must correspond with the name(s) as written on the face of the
certificates without alteration, enlargement or any change whatsoever.
 
     If any of the Shares tendered under either Tender Document is held of
record by two or more persons, all such persons must sign such Tender Document.
 
     If any of the Shares tendered under either Tender Document is registered in
different names or different certificates, it will be necessary to complete,
sign and submit as many separate applicable Tender Documents as there are
different registrations or certificates.
 
     If either Tender Document is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made to, or Shares
not tendered or not purchased are to be registered in the name of, any person
other than the registered holder(s). Signatures on any such certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
     If either Tender Document or any certificate or stock power is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and proper evidence satisfactory to
AEP of the authority of such person so to act must be submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, AEP
will pay or cause to be paid any stock transfer taxes with respect to the sale
and transfer of any Shares to it or its order pursuant to the Offer. If,
however, payment of the purchase price is to be made to, or Shares not tendered
or not purchased are to be registered in the name of, any person other than the
registered holder(s), or if tendered Shares are registered in the name of any
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s), such
other person or otherwise) payable on account of the transfer to such person
will be deducted from the purchase price unless satisfactory evidence of the
payment of such taxes, or exemption therefrom, is submitted. See "Terms of the
Offer -- Acceptance of Shares for Payment and Payment of Purchase Price and
Dividends" in the Offer to Purchase and Proxy Statement. EXCEPT AS PROVIDED IN
THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE
CERTIFICATES REPRESENTING SHARES TENDERED HEREBY.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, and/or
any Shares not tendered or not purchased are to be returned to, a person other
than the person(s) signing this Letter of Transmittal or if the check and/or any
certificate for Shares not tendered or not purchased are to be mailed to someone
other than the person(s) signing this Letter of Transmittal or to an address
other than that shown in the box above under the heading "Name(s) and
Address(es) of Registered Holder(s)", then the "Special Payment Instructions"
and/or "Special Delivery Instructions" on this Letter of Transmittal should be
completed. Preferred Shareholders tendering Shares by book-entry transfer will
have any Shares not accepted for payment returned by crediting the account
maintained by such Preferred Shareholder at the Book-Entry Transfer Facility
from which such transfer was made.
 
     8.  SUBSTITUTE FORM W-9 AND FORM W-8.  The tendering Preferred Shareholder
is required to provide the Depositary with either a correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided under
"Important Tax Information" below, or a properly completed Form W-8. Failure to
provide the information on either Substitute Form W-9 or Form W-8 may subject
the tendering Preferred Shareholder to a $50 penalty imposed by the Internal
Revenue Service and to 31% federal income tax backup withholding on the payment
of the purchase price for the Shares. The box in Part 2 of Substitute Form W-9
may be checked if the tendering Preferred Shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future. If the box in Part 2 is checked and the Depositary is not provided with
a TIN by the time of payment, the Depositary will withhold 31% on all payments
of the purchase price for the Shares thereafter until a TIN is provided to the
Depositary.
 
     9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or
requests for assistance may be directed to the Information Agent or the Dealer
Managers at their respective telephone numbers and addresses listed below.
Requests for additional copies of the Offer to Purchase and Proxy Statement,
this Letter of Transmittal or other tender offer materials may be directed to
the Information Agent and such copies will be furnished promptly at AEP's
expense. Preferred Shareholders may also contact their local broker, dealer,
commercial bank or trust company for assistance concerning the Offer.
<PAGE>   48
 
     10. SOLICITED TENDERS.  AEP will pay a solicitation fee of $.50 per Share
for any Shares tendered, accepted for payment and paid pursuant to the Offer,
covered by the Letter of Transmittal which designates, under the heading
"Solicited Tenders", as having solicited and obtained the tender, the name of
(a) any broker or dealer in securities, including a Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the National Association of Securities Dealers, Inc. (the
"NASD"), (b) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in soliciting
tenders outside the United States to the same extent as though it were an NASD
member, or (c) any bank or trust company (each of which is referred to herein as
a "Soliciting Dealer"). No such fee shall be payable to a Soliciting Dealer with
respect to the tender of Shares by a holder unless the Letter of Transmittal
accompanying such tender designates such Soliciting Dealer. No such fee shall be
payable to a Soliciting Dealer in respect of Shares registered in the name of
such Soliciting Dealer unless such Shares are held by such Soliciting Dealer as
nominee and such Shares are being tendered for the benefit of one or more
beneficial owners identified on the Letter of Transmittal or on the Notice of
Solicited Tenders (included in the materials provided to brokers and dealers).
No such fee shall be payable to a Soliciting Dealer with respect to the tender
of Shares by the holder of record, for the benefit of the beneficial owner,
unless the beneficial owner has designated such Soliciting Dealer. If tendered
Shares are being delivered by book-entry transfer, the Soliciting Dealer must
return a Notice of Solicited Tenders to the Depositary within three business
days after expiration of the Offer to receive a solicitation fee. No such fee
shall be payable to a Soliciting Dealer if such Soliciting Dealer is required
for any reason to transfer the amount of such fee to a depositing holder (other
than itself). No such fee shall be paid to a Soliciting Dealer with respect to
Shares tendered for such Soliciting Dealer's own account. No broker, dealer,
bank, trust company or fiduciary shall be deemed to be the agent of AEP, the
Depositary, the Information Agent or the Dealer Managers for purposes of the
Offer.
 
     Soliciting Dealers will include any organizations described in clauses (a),
(b) or (c) above even when the activities of such organization in connection
with the Offer consist solely of forwarding to clients materials relating to the
Offer, including this Letter of Transmittal, and rendering Shares as directed by
beneficial owners thereof. No Soliciting Dealer is required to make any
recommendation to holders of Shares as to whether to tender or refrain from
tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
     11. IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including time of receipt) and acceptance of any tender
of Shares will be determined by AEP, in its sole discretion, and its
determination shall be final and binding. AEP reserves the absolute right to
reject any and all tenders of Shares that it determines are not in proper form
or the acceptance for payment of or payment for Shares that may, in the opinion
of AEP's counsel, be unlawful. AEP also reserves the absolute right to waive any
of the conditions to the Offer or any defect or irregularity in any tender of
Shares and AEP's interpretation of the terms and conditions of the Offer
(including these instructions) shall be final and binding. Unless waived, any
defects or irregularities in connection with tenders must be cured within such
time as AEP shall determine. None of AEP, APCo, the Dealer Managers, the
Depositary, the Information Agent or any other person shall be under any duty to
give notice of any defect or irregularity in tenders, nor shall any of them
incur any liability for failure to give any such notice. Tenders will not be
deemed to have been made until all defects and irregularities have been cured or
waived.
 
     12. LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
1-800-649-2153. In addition, you should advise the Depositary of any
certificate(s) you have in your possession. You will need to complete an
Affidavit of Loss with respect to the lost certificate(s) (which will be
provided by the Depositary) and pay an indemnity bond premium fee. The tender of
Shares pursuant to this Letter of Transmittal will not be valid unless prior to
the Expiration Date: (a) such procedures have been completed and a replacement
certificate for the Shares has been delivered to the Depositary or (b) a Notice
of Guaranteed Delivery has been delivered to the Depositary. See Instruction 2.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL, DULY EXECUTED, TOGETHER WITH, IF
APPLICABLE, CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER, AND ALL OTHER
REQUIRED DOCUMENTS MUST BE RECEIVED BY THE DEPOSITARY, OR, IF APPLICABLE, THE
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO
THE APPLICABLE EXPIRATION DATE.
 
                           IMPORTANT TAX INFORMATION
 
     Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment is required to provide the Depositary (as payer) with
either such Preferred Shareholder's correct TIN on Substitute Form W-9 below or
a properly completed Form W-8. If such Preferred Shareholder is an individual,
the TIN is his or her social security number. For businesses and other entities,
the number is the federal employer identification number. If the Depositary is
not provided with the correct TIN or properly completed Form W-8, the Preferred
Shareholder may be subject to a $50 penalty imposed by the Internal Revenue
Code. In addition, payments that are made to such Preferred Shareholder with
respect to Shares purchased pursuant to the Offer may be subject to 31% backup
withholding.
<PAGE>   49
 
     Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Internal Revenue
Service Form W-8 (a "Form W-8"), signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A Form W-8 can be obtained from the
Depositary. See the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional instructions.
 
     If federal income tax backup withholding applies, the Depositary is
required to withhold 31% of any payments made to the Preferred Shareholder.
Backup withholding is not an additional tax. Rather, the Federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of the tax withheld. If withholding results in an overpayment of taxes, a refund
may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
     To avoid backup withholding on payments that are made to a Preferred
Shareholder with respect to Shares purchased pursuant to the Offer, the
Preferred Shareholder is required to notify the Depositary of his or her correct
TIN by completing the Substitute Form W-9 attached hereto certifying that the
TIN provided on Substitute Form W-9 is correct and that (a) the Preferred
Shareholder has not been notified by the Internal Revenue Service that he or she
is subject to federal income tax backup withholding as a result of failure to
report all interest or dividends or (b) the Internal Revenue Service has
notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed Form W-8 in order to avoid the applicable backup
withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The Preferred Shareholder is required to give the Depositary the social
security number or employer identification number of the registered owner of the
Shares. If the Shares are in more than one name or are not in the name of the
actual owner, consult the enclosed Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9 for additional guidance on which
number to report.

                                                                January 30, 1997
 
To Brokers, Dealers, Commercial Banks,
  Trust Companies and Other Nominees:
 
    We have been appointed by American Electric Power Company, Inc., a New York
corporation ("AEP"), to act as Dealer Managers and in connection therewith are
enclosing the material listed below relating to the invitation of AEP to the
holders of each series of cumulative preferred stock of Appalachian Power
Company, a Virginia corporation and direct utility subsidiary of AEP ("APCo"),
listed above (each a "Series of Preferred") to tender any and all of their
shares of a Series of Preferred ("Shares") for purchase at the purchase price
per Share listed above plus accrued and unpaid dividends, net to the seller in
cash, upon the terms and subject to the conditions set forth in the Offer to
Purchase and Proxy Statement, dated January 30, 1997 (the "Offer to Purchase and
Proxy Statement"), the proxy, and in the Letter of Transmittal for the Shares
tendered. As to each Series of Preferred, the Offer to Purchase and Proxy
Statement, together with the applicable Letter of Transmittal, constitutes the
"Offer." AEP will purchase all Shares validly tendered and not withdrawn, upon
the terms and subject to the conditions of the Offer. The Offer for a Series of
Preferred is not conditioned upon any minimum number of Shares of such Series of
Preferred being tendered and is independent of the Offer for any other Series of
Preferred. WHILE PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER NEED NOT VOTE IN FAVOR OF THE PROPOSED AMENDMENT TO APCO'S AMENDED
ARTICLES OF INCORPORATION, AS SET FORTH IN THE OFFER TO PURCHASE AND PROXY
STATEMENT (THE "PROPOSED AMENDMENT"), THE OFFER IS CONDITIONED UPON THE PROPOSED
AMENDMENT BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING (AS DEFINED IN THE
OFFER TO PURCHASE AND PROXY STATEMENT). IN ADDITION, PREFERRED SHAREHOLDERS OF
RECORD HAVE THE RIGHT TO VOTE FOR OR AGAINST THE PROPOSED AMENDMENT REGARDLESS
OF WHETHER THEY TENDER THEIR SHARES BY CASTING THEIR VOTE AND SIGNING THE PROXY
ENCLOSED HEREWITH OR BY VOTING IN PERSON AT THE SPECIAL MEETING. IF THE PROPOSED
AMENDMENT IS APPROVED AND ADOPTED BY APCO'S SHAREHOLDERS, APCO WILL MAKE A
SPECIAL CASH PAYMENT IN THE AMOUNT OF $1.00 PER SHARE TO EACH PREFERRED
SHAREHOLDER WHO VOTED IN FAVOR OF THE PROPOSED AMENDMENT, PROVIDED THAT SUCH
SHARES HAVE NOT BEEN TENDERED PURSUANT TO THE OFFER. SEE "PROPOSED AMENDMENT AND
PROXY SOLICITATION", "TERMS OF THE OFFER -- CERTAIN CONDITION OF THE OFFER" AND
"TERMS OF THE OFFER -- EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT" IN
THE OFFER TO PURCHASE AND PROXY STATEMENT.
 
    We are asking you to contact your clients for whom you hold Shares
registered in your name (or in the name of your nominee) or who hold Shares
registered in their own names. Please bring the Offer to their attention as
promptly as possible.
 
    AEP will pay to each designated Soliciting Dealer a solicitation fee of
$1.50 per Share for Shares of the 4 1/2% Series that are tendered, accepted for
payment and paid for pursuant to the Offer (except that for transactions for
beneficial owners equal to or exceeding 5,000 Shares, AEP will pay a
solicitation fee of $1.00 per Share). AEP will pay a solicitation fee of $.50
per Share for Shares of the 5.90% Series, the 5.92% Series, the 6.85% Series and
the 7.80% Series which are tendered, accepted for payment and paid pursuant to
the Offer; provided, however, that any fee payable pursuant to this sentence
shall be paid 80% to the Dealer Managers and 20% to any Soliciting Dealer (which
may be a Dealer Manager). APCo will pay to each designated Soliciting Dealer a
separate fee of $.50 per Share for Shares of the 4 1/2% Series that are not
tendered pursuant to the Offer but which are voted in favor of the Proposed
Amendment. A designated Soliciting Dealer is an entity obtaining the tender or
proxy, if the Letter of Transmittal or proxy, as the case may be, shall include
its name and it is (i) any broker or dealer in securities, including the Dealer
Managers in their capacity as a broker or dealer, which is a member of any
national securities exchange or of the National Association of Securities
Dealers, Inc. (the "NASD"), (ii) any foreign broker or dealer not eligible for
membership in the NASD which agrees to conform to the NASD's Rules of Fair
Practice in soliciting tenders outside the United States to the same extent as
though it were an NASD member, or (iii) any bank or trust company. No
solicitation fee or separate fee (other than solicitation fees payable to the
Dealer Managers as provided above) shall be payable to a Soliciting Dealer with
respect to the tender of Shares or the vote of Shares by a holder unless the
Letter of Transmittal or proxy accompanying such tender or vote, as the case may
be, designates such Soliciting Dealer. No solicitation fee or separate fee shall
be payable to a Soliciting Dealer in respect of Shares registered in the name of
such Soliciting Dealer unless such Shares are held by such Soliciting Dealer as
nominee and such Shares are being tendered or voted for the benefit of one or
more beneficial owners identified on the Letter of Transmittal or on the Notice
of Solicited Tenders (included below). No solicitation fee or separate fee shall
be payable to a Soliciting Dealer if such Soliciting Dealer is required for any
reason to transfer the amount of such fee to a depositing holder (other than
itself). No solicitation fee shall be paid to a Soliciting Dealer with respect
to Shares tendered for such Soliciting Dealer's own account and no separate fee
shall be paid to a Soliciting Dealer with respect to Shares voted for such
Soliciting Dealer's own account. A Soliciting Dealer shall not be entitled to a
solicitation fee or a separate fee for Shares beneficially owned by such
Soliciting Dealer. No broker, dealer, bank, trust company or fiduciary shall be
deemed to be the agent of AEP, APCo the Depositary (as defined below), the
Dealer Managers or the Information Agent (as defined below) for purposes of the
Offer.
<PAGE>   2
 
    Soliciting Dealers will include any of the organizations described in
clauses (i), (ii) and (iii) above even when the activities of such organizations
in connection with the Offer consist solely of forwarding to clients materials
relating to the Offer, including the Letter of Transmittal and tendering Shares
as directed by beneficial owners thereof. No Soliciting Dealer is required to
make any recommendation to holders of Shares as to whether to tender or refrain
from tendering in the Offer. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered" or "forwarding to customers materials
regarding the Offer."
 
    AEP will also, upon request, reimburse Soliciting Dealers for reasonable and
customary handling and mailing expenses incurred by them in forwarding materials
relating to the Offer to their customers. AEP will pay all stock transfer taxes
applicable to its purchase of Shares pursuant to the Offer, subject to
Instruction 6 of the Letter of Transmittal.
 
    In order for a Soliciting Dealer to receive a solicitation fee or a separate
fee, First Chicago Trust Company of New York, as Depositary (the "Depositary"),
must have received from such Soliciting Dealer a properly completed and duly
executed Notice of Solicited Tenders and Proxies in the form attached hereto
within three business days after the expiration of the Offer or a properly
executed Proxy on or before the Expiration Date.
 
    For your information and for forwarding to your clients for whom you hold
Shares registered in your name (or in the name of your nominee), we are
enclosing the following documents:
 
        1. The Offer to Purchase and Proxy Statement, dated January 30, 1997.
 
        2. A separate Letter of Transmittal for each Series of Preferred for
    your use and for the information of your clients.
 
        3. A Proxy.
 
        4. A letter to shareholders of APCo from its Chairman of the Board and
    Chief Executive Officer.
 
        5. A Notice of Guaranteed Delivery to be used to accept the Offer if the
    Shares and all other required documents cannot be delivered to the
    Depositary by the applicable Expiration Date (as defined in the Offer to
    Purchase and Proxy Statement).
 
        6. A form of letter which may be sent to your clients for whose accounts
    you hold Shares registered in your name or in the name of your nominee, with
    space for obtaining such clients' instructions with regard to the Offer and
    with regard to the proxy solicitation by APCo.
 
        7. Guidelines of the Internal Revenue Service for Certification of
    Taxpayer Identification Number on Substitute Form W-9, providing information
    relating to backup federal income tax withholding.
 
        8. A return envelope addressed to First Chicago Trust Company of New
    York, the Depositary.
 
        9. Cover Letter containing Summary Simplified Instructions.
 
    EACH SERIES OF PREFERRED HAS ITS OWN LETTER OF TRANSMITTAL, AND ONLY THE
APPLICABLE LETTER OF TRANSMITTAL FOR A PARTICULAR SERIES OR A NOTICE OF
GUARANTEED DELIVERY MAY BE USED TO TENDER SHARES OF SUCH SERIES OF PREFERRED.
 
    WE URGE YOU TO CONTACT YOUR CLIENTS AS PROMPTLY AS POSSIBLE. PLEASE NOTE

TIME, ON FRIDAY, FEBRUARY 28, 1997, UNLESS THE OFFER IS EXTENDED.
 
    NEITHER AEP, APCO, THEIR RESPECTIVE BOARDS OF DIRECTORS NOR ANY OF THEIR
RESPECTIVE OFFICERS MAKES ANY RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO
WHETHER TO TENDER ANY OR ALL SHARES. EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR
HER OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO
TENDER.

To Our Clients:
 
    Enclosed for your consideration are the Offer to Purchase and Proxy
Statement, dated January 30, 1997, a proxy and a separate Letter of Transmittal
for each series of cumulative preferred stock listed above (each a "Series of
Preferred" and the holder thereof a "Preferred Shareholder") of Appalachian
Power Company ("APCo"), a Virginia corporation and direct utility subsidiary of
American Electric Power Company, Inc. ("AEP"), of which you own shares. As to
each Series of Preferred, the Offer to Purchase and Proxy Statement, together
with the applicable Letter of Transmittal, constitutes the "Offer" of AEP to
purchase any and all shares of the Series of Preferred ("Shares") at the
purchase price per Share listed above plus accrued and unpaid dividends, net to
the seller in cash, upon the terms and subject to the conditions of the Offer.
AEP will purchase any and all Shares validly tendered and not withdrawn, upon
the terms and subject to the conditions of the Offer. The Offer for a Series of
Preferred is not conditioned upon any minimum number of Shares of such Series of
Preferred being tendered and is independent of the Offer for any other Series of
Preferred. While Preferred Shareholders who wish to tender their Shares pursuant
to the Offer need not vote in favor of the proposed amendment to APCo's Amended
Articles of Incorporation, as set forth in the Offer to Purchase and Proxy
Statement (the "Proposed Amendment"), the Offer is conditioned upon the Proposed
Amendment being approved and adopted at the Special Meeting (as defined in the
Offer to Purchase and Proxy Statement). APCo's Board of Directors recommends
voting for the Proposed Amendment. In addition, Preferred Shareholders have the
right to vote for or against the Proposed Amendment regardless of whether they
tender their Shares. If the Proposed Amendment is approved and adopted by APCo's
shareholders, APCo will make a special cash payment in the amount of $1.00 per
Share to each Preferred Shareholder who voted in favor of the Proposed
Amendment, provided that such Shares have not been tendered pursuant to the
Offer. See "Proposed Amendment and Proxy Solicitation", "Terms of the
Offer -- Certain Conditions of the Offer" and "Terms of the Offer -- Extension
of Tender Period; Termination; Amendments" in the Offer to Purchase and Proxy
Statement.
 
    WE ARE THE HOLDER OF RECORD OF SHARES HELD FOR YOUR ACCOUNT BUT NOT
REGISTERED IN YOUR NAME. A TENDER OR A VOTE OF SUCH SHARES CAN BE MADE ONLY BY
US AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. ANY LETTER OF
TRANSMITTAL OR PROXY FURNISHED TO YOU IS SOLELY FOR YOUR INFORMATION AND CANNOT
BE USED BY YOU TO TENDER OR VOTE SHARES HELD BY US FOR YOUR ACCOUNT.
 
    We request instructions as to whether you wish us to tender and/or vote any
or all of the Shares held by us for your account, upon the terms and subject to
the conditions set forth in the Offer.
 
    PLEASE READ THE FOLLOWING INFORMATION CAREFULLY:
 
        (1) The Offer is for any and all Shares outstanding as of January 30,
    1997. The Offer for a Series of Preferred is independent of the Offer for
    any other Series of Preferred.
 
        (2) The Offer and withdrawal rights will expire at 5:00 p.m., New York
    City time, on February 28, 1997, unless the Offer is extended with respect
    to a Series of Preferred. Your instructions to us should be forwarded to us
    in ample time to permit us to submit a tender on your behalf by the
    expiration of the Offer. If you would like to withdraw your Shares that we
    have tendered, you can withdraw them so long as the Offer remains open or at
    any time after the expiration of forty business days from the commencement
    of the Offer if such tendered Shares have not been accepted for payment.
 
        (3) While Preferred Shareholders who wish to tender their Shares
    pursuant to the Offer need not vote in favor of the Proposed Amendment, the
    Offer is conditioned upon the Proposed Amendment being approved and adopted
    at the Special Meeting.
 
        (4) Preferred Shareholders have the right to vote for or against the
    Proposed Amendment regardless of whether they tender their Shares. If the
    Proposed Amendment is approved and adopted by APCo's shareholders, APCo will
    make a special cash payment in the amount of $1.00 per Share to each
    Preferred Shareholder who voted in favor of the Proposed Amendment, provided
    that such Shares have not been tendered pursuant to the Offer.
 
        (5) Any stock transfer taxes applicable to the sale of Shares to AEP
    pursuant to the Offer will be paid by AEP, except as otherwise provided in
    Instruction 6 of the Letter of Transmittal.
 
    NEITHER AEP, APCO, THEIR RESPECTIVE BOARDS OF DIRECTORS NOR ANY OF THEIR
RESPECTIVE OFFICERS MAKES ANY RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO
WHETHER TO TENDER ANY OR ALL SHARES. EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR
HER OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO
TENDER.
<PAGE>   2
 
     If you wish to have us tender and/or vote any or all of your Shares held by
us for your account upon the terms and subject to the conditions set forth in
the Offer, please so instruct us by completing, executing, detaching and
returning to us the instruction form on the detachable part hereof. An envelope
to return your instructions to us is enclosed. If you authorize tender of your
Shares, all such Shares will be tendered unless otherwise specified on the
detachable part hereof. Your instructions should be forwarded to us in ample
time to permit us to submit a tender and/or vote on your behalf by the
expiration of the Offer or the Special Meeting, as applicable.
 
     The Offer is being made to all holders of Shares. AEP is not aware of any
state where the making of the Offer is prohibited by administrative or judicial
action pursuant to a valid state statute. If AEP becomes aware of any valid
state statute prohibiting the making of the Offer, AEP will make a good faith
effort to comply with such statute. If, after such good faith effort, AEP cannot
comply with such statute, the Offer will not be made to, nor will tenders be
accepted from or on behalf of, holders of Shares in such state. In those
jurisdictions where the securities, blue sky or other laws require the Offer to
be made by a licensed broker or dealer, the Offer shall be deemed to be made on
behalf of AEP by the Dealer Managers (as defined in the Offer) or one or more
registered brokers or dealers licensed under the laws of such jurisdictions.

 ----------------------------------------------------------------------------

        THE OFFER FOR A SERIES OF PREFERRED IS NOT CONDITIONED UPON ANY MINIMUM
NUMBER OF SHARES OF SUCH SERIES OF PREFERRED BEING TENDERED AND IS INDEPENDENT
OF THE OFFER FOR ANY OTHER SERIES OF PREFERRED. THE OFFER OF EACH COMPANY,
HOWEVER, IS CONDITIONED UPON, AMONG OTHER THINGS, THE PROPOSED AMENDMENT, AS
DESCRIBED BELOW, BEING APPROVED AND ADOPTED AT THE SPECIAL MEETING RELATING TO
SUCH COMPANY. SEE "TERMS OF THE OFFER -- CERTAIN CONDITIONS OF THE OFFER" IN
THE OFFER TO PURCHASE AND PROXY STATEMENT WITH RESPECT TO EACH COMPANY.

        Concurrently with each Offer, the Board of Directors of each Company is

Company to be held at AEP's principal office, 1 Riverside Plaza, Columbus, Ohio
43215, on February 28, 1997 or any adjournment or postponement of such meetings
(collectively, the "Special Meeting"). Each Special Meeting is being held to
consider amendments (collectively, the "Proposed Amendment") to each Company's
articles of incorporation (collectively, the "Articles") which would remove
similar provisions of each Company's Articles that limit each Company's ability
to issue debt. The Board of Directors of each Company recommends voting for the
Proposed Amendments relating to such Company. WHILE TENDERING HOLDERS OF A
SERIES OF PREFERRED OF EACH COMPANY NEED NOT VOTE IN FAVOR OF THE PROPOSED
AMENDMENT RELATING TO SUCH COMPANY, THE OFFER, WITH RESPECT TO SUCH COMPANY, IS
CONDITIONED UPON SUCH PROPOSED AMENDMENT BEING APPROVED AND ADOPTED AT SUCH
COMPANY'S SPECIAL MEETING. IN ADDITION, RECORD HOLDERS OF EACH COMPANY'S SHARES
HAVE THE RIGHT TO VOTE FOR OR AGAINST THE PROPOSED AMENDMENT RELATING TO SUCH
COMPANY REGARDLESS OF WHETHER THEY TENDER THEIR SHARES. IF A PROPOSED AMENDMENT
IS APPROVED AND ADOPTED BY A COMPANY'S HOLDERS, THE COMPANY WILL MAKE A SPECIAL
CASH PAYMENT IN THE AMOUNT OF $1.00 PER SHARE TO EACH HOLDER WHO VOTED IN FAVOR
OF THE PROPOSED AMENDMENT, PROVIDED THAT SUCH SHARES HAVE NOT BEEN TENDERED
PURSUANT TO THE OFFER. THOSE HOLDERS WHO VALIDLY TENDER THEIR SHARES WILL BE
ENTITLED ONLY TO THE PURCHASE PRICE PER SHARE LISTED ABOVE.

        Any holder of a Series of Preferred desiring to accept the Offer and
tender all or any portion of his or her Shares should either (i) request his or
her broker, dealer, commercial bank, trust company or nominee to effect the
transaction for him or her, or (ii) complete and sign the Letter of Transmittal
in accordance with the instruction in the Letter of Transmittal, mail or
deliver the same and any other required documents to First Chicago Trust
Company of New York (The "Depositary"), and deliver the certificates for such
Shares to the Depositary, along with the Letter of Transmittal, or tender such
Shares pursuant to the procedure for book-entry transfer set forth in the
applicable Offer to Purchase and Proxy Statement under "Terms of the Offer --
Procedures of Tendering Shares," on or prior to the Expiration Date (set forth
above). A holder of a Series of Preferred whose Shares are registered in the
name of a broker, dealer, commercial bank, trust company or nominee must
contact such broker, dealer, commercial bank, trust company or nominee if he or
she desires to tender such Shares. Any holder of a Series of Preferred who
desires to tender Shares and whose certificates for such Shares are not
immediately available, or who cannot comply in a timely manner with the
procedure for book-entry transfer, should tender such Shares by following the
procedures for guaranteed delivery set forth in the applicable Offer to
Purchase and Proxy Statement under "Terms of the Offer -- Procedures for
Tendering Shares." AEP will pay to each soliciting dealer a solicitation fee
for any Shares tendered, accepted for payment and paid pursuant to the Offer.
See "Fees And Expenses Paid To Dealers" in each Company's Offer to Purchase and
Proxy Statement.

        EACH SERIES OF PREFERRED HAS ITS OWN LETTER OF TRANSMITTAL, AND ONLY
THE APPLICABLE LETTER OF TRANSMITTAL FOR SUCH SERIES OF PREFERRED OR A NOTICE
OF GUARANTEED DELIVERY MAY BE USED TO TENDER SHARES OF SUCH SERIES OF PREFERRED.

        NEITHER AEP, APCO, I&M, OPCO, THEIR RESPECTIVE BOARDS OF DIRECTORS, NOR
ANY OF THEIR RESPECTIVE OFFICERS MAKES ANY RECOMMENDATION TO ANY SHAREHOLDER AS
TO WHETHER TO TENDER ANY OR ALL SHARES. EACH SHAREHOLDER MUST MAKE HIS OR HER
OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO 
TENDER.

        The Offer to Purchase and Proxy Statement with respect to each Company
is first being mailed on or about January 30, 1997 to Preferred Shareholders of
record on January 27, 1997.

Dear Shareholder:
 
     Please find enclosed important information pertaining to the following two
items:
 
          (i) a proposed amendment to the Amended Articles of Incorporation (the
     "Articles") of Appalachian Power Company ("APCo" or "the Company") which
     will be considered at a Special Meeting of its shareholders; and
 
          (ii) an offer by American Electric Power Company, Inc. ("AEP") to
     purchase the outstanding shares of APCo's cumulative preferred stock.
 
     We will greatly appreciate your giving prompt attention to the enclosed
material which you are urged to read in its entirety.
 
     The Articles presently limit APCo's ability (i) to issue securities
representing secured or unsecured indebtedness, including short-term debt, to no
more than 20% of the aggregate of its capital, surplus and certain secured debt
and (ii) to issue or assume unsecured indebtedness of maturities less than ten
years to no more than 10% of the aggregate of its capital, surplus and secured
debt. These debt restrictions limit APCo's flexibility in planning and financing
its business activities. With financial flexibility and capital cost reduction
being crucial factors to being successful in the evolving competitive utility
environment, APCo ultimately may be placed at a competitive disadvantage if the
debt restrictions are not removed from the Articles. The proposed amendment, as
set forth and explained in the enclosed Offer to Purchase and Proxy Statement,
dated January 30, 1997, would remove the debt restrictions.
 
     Concurrently with APCo's proxy solicitation, AEP is offering to purchase
the outstanding shares of APCo's cumulative preferred stock. While you need not
vote in favor of the proposed amendment in order to tender your shares, AEP's
offer is conditioned upon, among other things, the proposed amendment being
approved and adopted at the Special Meeting. In addition, you have the right to
vote for or against the proposed amendment regardless of whether you tender your
shares. If you vote in favor of the proposed amendment and it passes, you will
be entitled to receive a special cash payment in the amount of $1.00 per share
for each share that you vote, provided your shares have not been tendered.
Instructions for tendering your shares and information pertaining to the special
cash payment are included with the enclosed material.
 
     It is important to your interests that all shareholders, regardless of the
number of shares owned, participate in the affairs of the Company. Even if you
plan to attend the Special Meeting, WE URGE YOU TO MARK, SIGN AND DATE THE
ENCLOSED PROXY AND RETURN IT PROMPTLY. By signing and returning your proxy
promptly, you are assuring that your shares will be voted.
 
     You are cordially invited to attend the Special Meeting which will be held
at AEP's principal office, 1 Riverside Plaza, Columbus, Ohio, on Friday,
February 28, 1997 at 4:00 p.m., eastern standard time or any adjournment or
postponement of such meeting.
 
     If you have questions regarding the proposed amendment, the Special Meeting
or AEP's tender offer, please call Merrill Lynch & Co. at (888) ML4-TNDR ((888)
654-8637 (toll free)) or Salomon Brothers Inc at (800) 558-3745 (toll free).
 
     Thank you for your continued interest in the Company.
 
                                          Sincerely yours,

FOR IMMEDIATE RELEASE -- JANUARY 30, 1997

APPALACHIAN POWER, INDIANA MICHIGAN POWER AND OHIO POWER SEEK ARTICLES
AMENDMENTS AT SPECIAL MEETINGS;
AMERICAN ELECTRIC POWER ANNOUNCES TENDER OFFER FOR APPALACHIAN POWER, INDIANA
MICHIGAN POWER AND OHIO POWER PREFERRED STOCK

     COLUMBUS  The boards of directors of Appalachian Power Company, Indiana
Michigan Power Company and Ohio Power Company, each a utility subsidiary of
American Electric Power Company, Inc. (NYSE:AEP), are soliciting proxies for use
at a special meeting of shareholders to be held on February 28, 1997. The
special meetings are being held to consider an amendment to each subsidiary's
articles of incorporation. The amendment would remove a provision of the
articles that limits the subsidiaries' ability to issue debt, including
short-term debt. These debt restrictions limit the subsidiaries' flexibility in
planning and financing their business activities. Since financial flexibility
and capital cost reduction are crucial factors to being successful in the
evolving competitive utility environment, the subsidiaries ultimately may be
placed at a competitive disadvantage if the debt restrictions are not removed.
Currently, power marketers, independent power producers and other utilities who
have taken similar action are not hampered by these debt restrictions.

     If a proposed amendment is approved and adopted, the subsidiary will make a
special cash payment in the amount of $1.00 per share to each preferred
shareholder who voted in favor of the proposed amendment, provided that such
shares are not tendered pursuant to AEP's offer. Those preferred shareholders
who validly tender their shares will be entitled only to the purchase price per
share listed below.
