                          AGREEMENT AND PLAN OF MERGER
 
    THIS AGREEMENT AND PLAN OF MERGER, dated as of December 21, 1997, is by and

    The Board of Directors of the Company has determined that the business
combination to be effected by means of the Merger is consistent with and in

Agreement by the stockholders of the Company.
 
    The Board of Directors of AEP has determined that the business combination

    The Board of Directors of Newco has determined that the business combination
to be effected by means of the Merger is in the best interests of Newco and its

                                  ARTICLE III
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES
 
    SECTION 3.1 MERGER CONSIDERATION; CONVERSION AND CANCELLATION OF SECURITIES.
On the date on which the Effective Time occurs, by virtue of the Merger and
without any action on the part of the AEP Companies, the Company or any
securityholder thereof:
 
                                      I-2

        (a) Subject to the other provisions of this Article III, each share of
    Company Common Stock issued and outstanding immediately prior to the
    Effective Time (exclusive of any shares to be cancelled pursuant to SECTION
    3.1(c)) shall be converted into that number of shares of AEP Common Stock
    equal to the Common Stock Exchange Ratio. If between the date of this
    Agreement and the Effective Time the outstanding shares of Company Common
    Stock or AEP Common Stock shall have been changed into a different number of
    shares or a different class, by reason of any dividend, subdivision,
    reclassification, recapitalization, split, combination, exchange of shares
    or other transaction, the Common Stock Exchange Ratio shall be
    correspondingly adjusted to reflect such dividend, subdivision,
    reclassification, recapitalization, split, combination, exchange of shares
    or other transaction.
 
        (b) All shares of Company Common Stock shall, upon conversion into
    shares of AEP Common Stock at the Effective Time, cease to be outstanding
    and shall automatically be cancelled and retired, and each certificate
    previously evidencing shares of Company Common Stock outstanding immediately
    prior to the Effective Time (exclusive of any shares to be cancelled
    pursuant to SECTION 3.1(c)) shall thereafter be deemed, for all purposes
    other than the payment of dividends or distributions, to represent that
    number of shares of AEP Common Stock into which such shares of Company
    Common Stock were converted pursuant to SECTION 3.1(a) and, if applicable,
    the right to receive cash pursuant to SECTION 3.2(e). The holders of
    certificates previously evidencing Company Common Stock shall cease to have
    any rights with respect to such Company Common Stock except as otherwise
    provided herein or by law.
 
        (c) Notwithstanding any provision of this Agreement to the contrary,
    each share of Company Common Stock held in the treasury of the Company and
    each share of Company Common Stock, if any, owned by AEP or any direct or
    indirect wholly owned subsidiary of AEP or of the Company immediately prior
    to the Effective Time shall be cancelled and extinguished without conversion
    thereof.
 
        (d) Each share of common stock, par value $.01 per share, of Newco
    issued and outstanding immediately prior to the Effective Time shall be
    converted into one share of common stock, par value $3.50 per share, of the
    Surviving Corporation.
 
    SECTION 3.2 EXCHANGE OF CERTIFICATES. (a) EXCHANGE FUND. On or prior to the
day of the Effective Time, AEP shall deposit, or cause to be deposited, with the
Exchange Agent, for the benefit of the holders of Company Common Stock, for
exchange in accordance with this Article III, through the Exchange Agent,
certificates evidencing a number of shares of AEP Common Stock into which the
number of shares of Company Common Stock issued and outstanding immediately
prior to the Effective Time was converted pursuant to SECTION 3.1(a). The
Exchange Agent shall, pursuant to irrevocable instructions from AEP, deliver AEP
Common Stock, together with any cash to be paid in lieu of fractional interests
in shares of AEP Common Stock pursuant to SECTION 3.2(e) and any dividends or
distributions related thereto, in exchange for certificates theretofore
evidencing Company Common Stock surrendered to the Exchange Agent pursuant to
SECTION 3.2(c). Except as contemplated by SECTION 3.2(f), the Exchange Fund
shall not be used for any other purpose.
 
    (b) LETTER OF TRANSMITTAL. Promptly after the Effective Time, AEP will cause
the Exchange Agent to send to each record holder of Company Common Stock
immediately prior to the Effective Time a letter of transmittal and other
appropriate materials for use in surrendering to the Exchange Agent certificates
that prior to the Effective Time evidenced shares of Company Common Stock.
 
    (c) EXCHANGE PROCEDURES. Promptly after the Effective Time, the Exchange
Agent shall distribute to each former holder of Company Common Stock, upon
surrender to the Exchange Agent for cancellation of one or more certificates
that theretofore evidenced shares of Company Common Stock, certificates
evidencing the appropriate number of shares of AEP Common Stock into which such
shares of Company Common Stock were converted pursuant to the Merger, together
with any cash to be paid in lieu of
 
                                      I-3

fractional interests in shares of AEP Common Stock pursuant to SECTION 3.2(e)
and any dividends or distributions related thereto. If shares of AEP Common
Stock are to be issued to a Person other than the Person in whose name the
surrendered certificate or certificates are registered, it shall be a condition
of issuance of AEP Common Stock that the surrendered certificate or certificates
shall be properly endorsed, with signatures guaranteed, or otherwise in proper
form for transfer and that the Person requesting such payment shall pay any
transfer or other taxes required by reason of the issuance of AEP Common Stock
to a Person other than the registered holder of the surrendered certificate or
certificates or such Person shall establish to the satisfaction of AEP that such
tax has been paid or is not applicable. Notwithstanding the foregoing, neither
the Exchange Agent nor any party hereto shall be liable to any former holder of
Company Common Stock for any AEP Common Stock, cash in lieu of fractional
interests or dividends or distributions thereon delivered to a public official
pursuant to any applicable escheat Law.
 
    (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF COMPANY COMMON
STOCK. No dividends or other distributions declared or made with respect to AEP
Common Stock with a record date after the Effective Time shall be paid to the
holder of any certificate that theretofore evidenced shares of Company Common
Stock until the holder of such certificate shall surrender such certificate.
Subject to the effect of any applicable escheat Laws, following surrender of any
such certificate, there shall be paid (i) to the holder of the certificates
evidencing whole shares of AEP Common Stock issued in exchange therefor, without
interest, (A) promptly, the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to such whole
shares of AEP Common Stock, and (B) at the appropriate payment date, the amount
of dividends or other distributions, with a record date after the Effective Time
but prior to surrender and a payment date occurring after surrender, payable
with respect to such whole shares of AEP Common Stock and (ii) to the holder of
any certificate that theretofore evidenced shares of Company Common Stock,
without interest, promptly the amount of any cash payable with respect to a
fractional interest in a share of AEP Common Stock to which such holder is
entitled pursuant to SECTION 3.2(e).
 
    (e) NO FRACTIONAL SHARES. Notwithstanding anything herein to the contrary,
no certificates or scrip evidencing fractional interests in shares of AEP Common
Stock shall be issued in connection with the Merger, and any such fractional
interests to which a holder of record of Company Common Stock at the Effective
Time would otherwise be entitled will not entitle such holder to vote or to any
rights of a stockholder of AEP. In lieu of any such fractional shares, each
holder of record of Company Common Stock at the Effective Time who but for the
provisions of this SECTION 3.2(e) would be entitled to receive a fractional
interest of a share of AEP Common Stock pursuant to the Merger shall be paid
cash, without any interest thereon, as hereinafter provided. AEP shall instruct
the Exchange Agent to determine the number of whole shares and fractional shares
of AEP Common Stock allocable to each holder of record of Company Common Stock
at the Effective Time, to aggregate all such fractional shares into whole
shares, to sell the whole shares obtained thereby in the open market at then
prevailing prices on behalf of holders who otherwise would be entitled to
receive fractional share interests and to distribute to each such holder such
holder's ratable share of the total proceeds of such sale, after making
appropriate deductions of the amount, if any, required for Federal income tax
withholding purposes and after deducting any applicable transfer taxes. All
brokers' fees and commissions and fees of the Exchange Agent incurred in
connection with such sales shall be paid by AEP.
 
    (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund which
remains unclaimed by the former holders of Company Common Stock for twelve
months after the Effective Time shall be delivered to AEP, upon demand, and any
former holders of Company Common Stock who have not theretofore complied with
this Article III shall thereafter look only to AEP for AEP Common Stock, any
cash to be paid in lieu of fractional interests in shares of AEP Common Stock
and any dividends or other distributions to which they are entitled.
 
    (g) WITHHOLDING OF TAX. AEP shall be entitled to deduct and withhold from
the consideration otherwise payable pursuant to this Agreement to any former
holder of Company Common Stock such
 
                                      I-4

amounts as AEP (or any affiliate thereof) is required to deduct and withhold
with respect to the making of such payment under the Code, or any provision of
state, local or foreign tax Law. To the extent that amounts are so withheld by
AEP, such withheld amounts shall be treated for all purposes of this Agreement
as having been paid to the former holder of Company Common Stock in respect of
which such deduction and withholding was made by AEP.
 
    (h) LOST CERTIFICATES. If any certificate evidencing shares of Company
Common Stock shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the Person claiming such certificate to be lost,
stolen or destroyed and, if required by AEP, the posting by such Person of a
bond, in such reasonable amount as AEP may direct, as indemnity against claims
that may be made against it with respect to such certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed certificate a
certificate evidencing that number of shares of AEP Common Stock into which the
shares of Company Common Stock evidenced by such lost, stolen or destroyed
certificate were converted pursuant to SECTION 3.1(a), any cash in lieu of
fractional interests in shares of AEP Common Stock to which the holder thereof
may be entitled pursuant to SECTION 3.2(e) and any dividends or other
distributions to which the holder thereof may be entitled pursuant to SECTION
3.2(d).
 
    SECTION 3.3 CLOSING. The Closing shall take place at such time and place as
the parties shall mutually agree on the second Business Day immediately
following the date on which the last of the conditions set forth in Article VIII
(other than conditions that by their nature are required to be performed on the
Closing Date) is fulfilled or, if permissible, waived, or at such other place,
time and date as the parties hereto may agree. At the conclusion of the Closing
on the Closing Date, the parties hereto shall cause the Certificate of Merger
relating to the Merger to be filed with the Secretary of State of the State of
Delaware.
 
    SECTION 3.4 STOCK TRANSFER BOOKS. At the Effective Time, the stock transfer
books of the Company shall be closed and there shall be no further registration
of transfers of shares of Company Common Stock thereafter on the records of the
Company.

    the Company's 1992 Long-term Incentive Plan or Directors' Compensation Plan
    (an "Outstanding Option") (whether or not vested) which remains as of such
    time unexercised in whole or in part and to substitute AEP Common Stock as
    purchasable under such assumed option ("Assumed Option"), with such
    assumption and substitution to be effected as follows:
 
           (A) The Assumed Option shall not give the optionee additional
       benefits which he did not have under the Outstanding Option before such
       assumption;
 
           (B) The number of shares of AEP Common Stock purchasable under any
       Assumed Option shall be equal to the number of whole shares of AEP Common
       Stock that the holder of the Outstanding Option being assumed would have

       exercised in full prior to the Merger;
 
           (C) The per share option price of the Assumed Option shall be equal
       to the per share option price of the Outstanding Option divided by the
       Common Stock Exchange Ratio; and

       benefit rights which he had under the Outstanding Option before such
       assumption.
 
                                      I-31

    Notwithstanding the foregoing, in the case of any Outstanding Option to
    which section 421 of the Code applies by reason of the qualification under
    section 422 of the Code, the exercise price, the number of shares
    purchasable pursuant to such option and the terms and conditions of exercise
    of such option shall comply with section 424(a) of the Code. As soon as
    practicable after the Effective Time, AEP shall deliver to the holders of
    the Outstanding Options appropriate agreements evidencing its assumption of
    such options.
 
        (ii) OTHER STOCK-BASED COMPENSATION. Effective as of the Effective Time,
    AEP agrees to assume the Company's 1992 Long-Term Incentive Plan and
    Director's Compensation Plan with respect to any stock-based compensation
    (other than the Outstanding Options) payable in the form of Company Common
    Stock as a result of the Merger ("Other Compensation"), and to substitute
    shares of AEP Common Stock with respect to such assumed Other Compensation.
    The number of shares of AEP Common Stock issuable with respect to such Other
    Compensation shall be equal to the number of whole shares of AEP Common
    Stock that the holder of Other Compensation being assumed would have
    received upon consummation of the Merger had such Other Compensation been
    paid in full prior to the Merger.
 
On or prior to the Effective Time, the Company shall take or cause to be taken
all such actions, reasonably satisfactory to AEP, as may be necessary or
desirable in order to authorize the transactions contemplated by subsections (i)
and (ii) above. Further, AEP shall take all corporate actions necessary to
reserve for issuance a sufficient number of shares of AEP Common Stock for
delivery upon exercise of the Company Outstanding Options or issuance of the
Company Other Compensation assumed by AEP pursuant to subsections (i) and (ii)
above. Prior to the Effective Time, AEP shall file one or more registration
statements on Form S-8 (or any successor or other appropriate forms) with
respect to the shares of AEP Common Stock issuable in respect to the Assumed
Options or Other Compensation and AEP Common Stock issuable in respect of the
Assumed Options or Other Compensation and AEP shall use its commercially
reasonable efforts to cause such registration statement to become effective
promptly after the Effective Time and to maintain the effectiveness of such
registration statement (and maintain the current status of the prospectus or
prospectuses contained herein) for so long as any Assumed Options remain
outstanding and to comply with applicable state securities and blue sky laws. So
long as any holder of an Assumed Options shall be subject to the reporting
requirements under Section 16(a) of the Exchange Act, AEP shall have the
Company's 1992 Long-Term Incentive Plan and Directors' Compensation Plan to be
administered in a manner that complies with Rule 16b-3 promulgated under the
Exchange Act.
 
    (b)  SEPARATE COMPANY PLANS.  From and after the Effective Time through July
1, 2002, AEP will continue or cause to be continued, without adverse change to
any employee or former employee of the Company or any of its Subsidiaries, the
Company Benefit Plans listed in Section 7.10(b) of the Company's Disclosure
Letter, except that (i) any Company Common Stock investment fund offered under a
Company Benefit Plan will be replaced by an AEP Common Stock investment fund or
a traditional investment fund as determined by AEP (ii) premiums charged to
participants may be increased under medical, dental, life, accidental death and
dismemberment, and disability insurance plans (except that premiums charged to
participants who retired from the Company or any of its Subsidiaries prior to
1993 (or survivors of such participants) may not be increased), and (iii)
changes required by law, including changes required to maintain the qualified
status of any Company Benefit Plan intended to be qualified under Section 401(a)
of the Code, may be made. After July 1, 2002, AEP will provide the employees of
the Company and its Subsidiaries with benefits that in the aggregate are at
least as favorable as the benefits provided to similarly situated employees of
AEP and its Subsidiaries. If, after July 1, 2002, an AEP Benefit Plan is made
available to employees of the Company or any of its Subsidiaries, all periods of
service with the Company and its Subsidiaries will be credited to such employees
for all purposes of the AEP Benefit Plan, including the accrual of benefits and
eligibility to receive benefits for which a specified period of service is
required under the AEP Benefit Plan. No earlier than July 1, 2002, the Company's
Cash Balance Retirement Plan shall be merged into a defined benefit pension plan
maintained by AEP or one of its
 
                                      I-32

Subsidiaries. The retirement benefit for employees of the Company or its
Subsidiaries who become participants in such merged plan will be determined
under the AEP pension plan formula for all years of service (including years of
service with the Company and its Subsidiaries) but such retirement benefit will
not be less than the benefit accrued under the Company's Cash Balance Retirement
Plan determined immediately prior to such plan merger plus the benefit
determined under the AEP pension plan formula for years of service beginning on
the date of such plan merger. If employees of the Company or any of its
Subsidiaries become participants in a health plan maintained by AEP or any of
its Subsidiaries, all preexisting condition limitations under the AEP health
plan for such employees will be waived. In addition, if such AEP health plan
participation becomes effective as of any date other than the first day of a
calendar year, such employees will receive credit under the AEP health plan for
any co-payments and deductibles incurred by such employees in the same calendar
year under the Company's Medical Plan.
 
    (c)  RETIREE AND DISABILITY BENEFITS.  From and after July 1, 2002, AEP will
provide access to retiree medical and life insurance coverage for any employee
or director of the Company or any of its Subsidiaries who retires or becomes
disabled prior to July 1, 2002 and who was eligible for such coverage under
plans of the Company and its Subsidiaries in effect on the date of such
individual's retirement. Further, for any such employees or directors who
retired or became disabled prior to 1993, such coverage shall be continued
without adverse change to such retired or disables employees or directors. In
addition, with respect to any such employee who becomes disabled before July 1,
2002, so long as such employee continues to satisfy the eligibility requirements
for disability benefits under the Company's Disability Income Plan in effect on
such date AEP will offer such disabled employee medical coverage without charge
to such disabled employee.
 
    (d)  CERTAIN NONQUALIFIED ARRANGEMENTS.  From and after the Effective Time
through July 1, 2002, AEP will maintain the Company's Supplemental Executive
Retirement Plan and Executive Deferred Compensation Plan without adverse change
to any employee participating in the Plan until all benefits have been paid in
accordance with the terms of the Plan; provided, however, that no deferrals
shall be permitted under such plan after the Effective Time. If the Company's
Supplemental Executive Retirement Plan or Executive Deferred Savings Plan is
terminated or otherwise discontinued after July 1, 2002, AEP will make available
to the class of employees of the Company and its Subsidiaries who were eligible
to participate in the Company's Supplemental Executive Retirement Plan or
Executive Deferred Savings Plan any nonqualified deferred compensation plan or
plans it maintains to supplement benefits in the AEP Benefit Plans that are
qualified plans. In addition, employees of the Company and its Subsidiaries will
be given credit for service with the Company and its Subsidiaries for all
purposes of such supplemental plans, and the supplemental plans will assume the
obligation of the Supplemental Executive Retirement Plan or the Executive
Deferred Savings Plan, as applicable, to pay the benefits that have accrued
under the Supplemental Executive Retirement Plan or the Executive Deferred
Savings Plan at the time of such termination or discontinuance.
 
    (e)  MEMORIAL GIFTS PROGRAM.  The Company will take all action necessary to
terminate the Memorial Gifts Program as of the Effective Time; provided,
however, that all then-existing commitments under such Program will not be
adversely affected by such termination and will be honored in accordance with
their terms.
 
    (f)  AGREEMENT BY AEP.  AEP agrees to honor without modification or contest,
and agrees to cause the Surviving Corporation to honor without modification or
contest, and to make required payments when due under all Change of Control
Agreements and all Retention Agreements, including any modifications to such
Change of Control Agreements or Retention Agreements permitted by Section
6.2(a).
 
    (g) The provisions of Sections 7.10(d) and (f) are intended to be for the
benefit of, and shall be enforceable by, each Person entitled to benefits or
payments thereunder and the heirs and representatives of such Person.

    SECTION 7.11  INDEMNIFICATION OF DIRECTORS AND OFFICERS.  (a) Until six
years from the Effective Time, the certificate of incorporation and bylaws of
the Company as the corporation surviving the Merger (in this Section 7.11 called
the "Surviving Corporation") as in effect immediately after the Effective Time
shall not be amended to reduce or limit the rights of indemnity afforded to the
present and former directors and officers of the Company thereunder or as to the
ability of the Company to indemnify such persons or to hinder, delay or make
more difficult the exercise of such rights of indemnity or the ability to
indemnify. The Surviving Corporation will at all times exercise the powers
granted to it by its certificate of incorporation, its bylaws and applicable law
to indemnify to the fullest extent possible the present and former directors,
officers, employees and agents of the Company against claims made against them
arising from their service in such capacities prior to the Effective Time.
 
    (b) If any claim or claims shall, subsequent to the Effective Time and
within six years thereafter, be made against any present or former director,
officer, employee or agent of the Company based on or arising out of the
services of such Person prior to the Effective Time in the capacity of such
Person as a director, officer, employee or agent of the Company, the provisions
of subsection (a) of this Section respecting the certificate of incorporation
and bylaws of the Surviving Corporation shall continue in effect until the final
disposition of all such claims.
 
    (c) AEP hereby agrees after the Effective Time to guarantee the payment of
the Surviving Corporation's indemnification obligations described in Section
7.11(a) up to an amount determined as of the Effective Time equal to (i) the
fair market value of any assets of the Surviving Corporation or any of its
Subsidiaries distributed to AEP or any of its Subsidiaries (other than the
Surviving Corporation and its Subsidiaries), minus (ii) any liabilities of the
Surviving Corporation or any of its Subsidiaries assumed by AEP or any of its
Subsidiaries (other than the Surviving Corporation and its Subsidiaries), minus
(iii) the fair market value of any assets of AEP or any of its Subsidiaries
(other than the Surviving Corporation and its Subsidiaries) contributed to the
Surviving Corporation or any of its Subsidiaries and (iv) plus any liabilities
of AEP or any of its Subsidiaries (other than the Surviving Corporation and its
Subsidiaries) assumed by the Surviving Corporation or any of its Subsidiaries.
 
    (d) Notwithstanding subsection (a), (b) or (c) of this Section 7.11, AEP and
the Surviving Corporation shall be released from the obligations imposed by such
subsection if AEP shall assume the obligations of the Surviving Corporation
thereunder by operation of Law or otherwise. Notwithstanding anything to the
contrary in this Section 7.11, neither AEP nor the Surviving Corporation shall
be liable for any settlement effected without its written consent, which shall
not be unreasonably withheld.
 
    (e) AEP shall cause to be maintained in effect until six years from the
Effective Time the current policies of directors' and officers' liability
insurance maintained by the Company (or substitute policies providing at least
the same coverage and limits and containing terms and conditions that are not
materially less advantageous) with respect to claims arising from facts or
events which occurred before the Effective Time; PROVIDED, HOWEVER, that in no
event shall AEP or the Surviving Corporation be required to expend more than 200
percent of the greater of (i) current annual premiums and (ii) annual premiums
for the year in which the Closing occurs paid by the Company for such insurance;
PROVIDED, FURTHER, that, if AEP or the Surviving Corporation is unable to obtain
insurance for any period for 200 percent of the greater of such annual premiums,
then the obligation of AEP and the Surviving Corporation pursuant hereto shall
be to obtain the best coverage reasonably available under the circumstances
subject to the foregoing limitations on premiums.
 
    (f) The provisions of this Section 7.11 are intended to be for the benefit
of, and shall be enforceable by, each Person entitled to indemnification
hereunder and the heirs and representatives of such Person.
 
    (g) AEP shall not permit the Surviving Corporation to merge or consolidate
with any other Person unless the Surviving Corporation shall ensure that the
surviving or resulting entity assumes the obligations imposed by subsections
(a), (b), (c) and (e) of this Section.

until the Effective Time, each party hereto shall promptly notify the other
party hereto of (i) the occurrence or nonoccurrence of any event the occurrence
or nonoccurrence of which would be likely to cause any condition to the
obligations of such party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied and (ii) the failure of such
party to comply with any covenant or agreement to be complied with by it
pursuant to this Agreement which would be likely to result in any condition to
the obligations of such party to effect the Merger and the other transactions
contemplated by this Agreement not to be satisfied. No delivery of any notice
pursuant to this Section 7.13 shall cure any breach of any representation or
warranty or any failure to comply with any covenant or agreement of such party
contained in this Agreement or otherwise limit or affect the remedies available
hereunder to the party receiving such notice.
 
    SECTION 7.14  BOARD OF DIRECTORS.  At the Effective Time, the Board of

or its Significant Subsidiaries' rates or charges (other than automatic cost
pass-through rate adjustment clauses), standards of service or accounting from
those in effect on the date hereof and consult with the other prior to making
any filing (or any amendment thereto), or effecting any agreement, commitment,
arrangement or consent with governmental regulators, whether written or oral,
formal or informal, with respect thereto (provided that except as otherwise
expressly provided herein each party shall retain discretion and control over
its affairs), and except as set forth in Section 7.16 of the Company's

standards of service or accounting that could reasonably be expected to have a
Material Adverse Effect on the Combined Companies.
 
    SECTION 7.17  COORDINATION OF DIVIDENDS.  Each of the Company and AEP shall
coordinate with the other regarding the declaration and payment of any dividends
in respect of the Company Common Stock and AEP Common Stock and the record dates

best efforts to cause its and its Subsidiaries' employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) not to,
 
                                      I-35

the case may be, shall not have been obtained, (ii) the Board of Directors of
AEP or the Company, as the case may be, concludes in good faith that such

reasonably be expected to constitute a Superior Proposal, (iii) the Board of
Directors of AEP or the Company, as the case may be, determines in good faith
upon the basis of written advice of outside legal counsel that such action is

or data to any Person in connection with an Acquisition Proposal by any such
Person, the AEP Board of Directors or the Company Board of Directors, as the
case may be, receives from such Person an executed confidentiality agreement
containing customary terms and provisions and (v) prior to providing any

bargaining agreements, for a period of 2 years following the Effective Time, any

their Subsidiaries shall be made on a fair and equitable basis, in light of the
circumstances and the objectives to be achieved, giving consideration to
previous work history, job
 
                                      I-36

prospective Subsidiaries. Any workforce reductions carried out following the

Days after receipt of notice that the amount is due from the other party) pay to

    such party's shareholders) there shall have been an Acquisition Proposal
    involving the Company or AEP (as the case may be, the "Target Party") or any
    of its Affiliates which, at the time of such termination (or such meeting,

    and its Board of Directors and (y) withdrawn by the third party; and (iii)
    within eighteen months of any such termination described in clause (i)

    be, a termination fee equal to $225 million (the "Topping Fee") plus

    amount payable to the Company and its Affiliates pursuant to Section 9.6(a)
    and Section 9.6(b) shall not exceed $245 million.

    exclusive remedy for any loss, liability, damage or claim arising out of or
    in connection with the transactions contemplated by this Agreement,
    including any termination of this Agreement pursuant to Section 9.1.

Ladies and Gentlemen:
 
    The undersigned has been advised that, as of the date hereof, the
undersigned may be deemed to be an "affiliate" of Central and South West
Corporation, a Delaware corporation (the "Company"), as that term is defined for
purposes of paragraphs (c) and (d) of Rule 145 of the Rules and Regulations (the
"Rules and Regulations") of the Securities and Exchange Commission (the "SEC")
under the Securities Act of 1933, as amended (the "Securities Act").
 
    Pursuant to the terms and subject to the conditions of that certain
Agreement and Plan of Merger by and among American Electric Power Company, Inc.,
a New York corporation ("AEP"), Augusta Acquisition Corporation, a newly formed
Delaware corporation and a wholly owned Subsidiary of AEP ("Newco"), and the
Company dated as of December 21, 1997 (the "Merger Agreement"), providing for,
among other things, the merger of Newco with and into the Company (the
"Merger"), the undersigned will be entitled to receive shares of common stock,
par value $6.50 per share ("AEP Common Stock"), of AEP in exchange for shares of
common stock, par value $3.50 per share ("Company Common Stock"), of the Company
owned by me at the effective time of the Merger (the "Effective Time") as
determined pursuant to the Merger Agreement.
 
    The undersigned understands that the Merger will be treated for financial
accounting purposes as a "pooling of interests" in accordance with generally
accepted accounting principles and that the staff of the SEC has issued certain
guidelines that should be followed to ensure the application of pooling of
interests accounting to the transaction.
 
    In consideration of the agreements contained herein, AEP's and the Company's
reliance on this letter in connection with the consummation of the Merger and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the undersigned hereby represents, warrants and agrees
that the undersigned has not made and will not make any sale, transfer or other
disposition of (i) Company Common Stock or AEP Common Stock within the 30 day
period prior to the date of the consummation of the Merger or (ii) AEP Common
Stock received by the undersigned pursuant to the Merger or otherwise owned by
the undersigned until after such time as financial statements of AEP that
include at least 30 days of combined operations of the Company and AEP after the
Merger shall have been publicly reported, unless the undersigned shall have
delivered to AEP, prior to any such sale, transfer or other disposition, a
written opinion from Deloitte & Touche L.L.P., independent public accountants
for AEP, or a written no-action letter from the accounting staff of the SEC, in
either case in form and substance reasonably satisfactory to AEP, to the effect
that such sale, transfer or other disposition will not cause the Merger not to
be treated as a "pooling of interests" for financial accounting purposes in
accordance with generally accepted accounting principles and the rules,
regulations and interpretations of the SEC and (iii) AEP Common Stock received
by the undersigned pursuant to the Merger in violation of the Securities Act or
the Rules and Regulations. The undersigned has been advised that the offering,
sale and delivery of the shares of AEP Common Stock pursuant to the Merger will
have been registered with
 
                                      B-1

the SEC under the Securities Act on a Registration Statement on Form S-4. The
undersigned has also been advised, however, that since the undersigned may be
deemed to be an affiliate of the Company at the time the Merger is submitted for
a vote of the stockholders of the Company, AEP Common Stock received by the
undersigned pursuant to the Merger can be sold by the undersigned only (i)
pursuant to an effective registration statement under the Securities Act of 1933
(the "Securities Act"), (ii) in conformity with the volume and other limitations
of Rule 145 promulgated by the SEC under the Securities Act, or (iii) in
reliance upon an exemption from registration that is available under the
Securities Act.
 
    The undersigned also understands that instructions will be given to the
transfer agent for AEP Common Stock with respect to AEP Common Stock to be
received by the undersigned pursuant to the Merger and that there will be placed
on the certificates representing such shares of AEP Common Stock, or any
substitutions therefor, a legend stating in substance as follows:
 
        "These shares were issued in a transaction to which Rule 145 promulgated
    under the Securities Act of 1933 applies. These shares may only be
    transferred in accordance with the terms of such Rule and an Affiliate's
    Agreement between the original holder of such shares and AEP, a copy of
    which agreement is on file at the principal offices of AEP."
 
It is understood and agreed that the legend set forth above shall be removed
upon surrender of certificates bearing such legend by delivery of substitute
certificates without such legend if the undersigned shall have delivered to AEP
an opinion of counsel, in form and substance reasonably satisfactory to AEP, to
the effect that (i) the sale or disposition of the shares represented by the
surrendered certificates may be effected without registration of the offering,
sale and delivery of such shares under the Securities Act and (ii) the shares to
be so transferred may be publicly offered, sold and delivered by the transferee
thereof without compliance with the registration provisions of the Securities
Act.
 
    By its execution hereof, AEP agrees that it will, as long as the undersigned
owns any AEP Common Stock to be received by the undersigned pursuant to the
Merger, take all reasonable efforts to make timely filings with the SEC of all
reports required to be filed by it pursuant to the Securities Exchange Act of
1934, as amended, and will promptly furnish upon written request of the
undersigned a written statement confirming that such reports have been so timely
filed.
