FOR IMMEDIATE RELEASE:


                       AEP, CSW AMEND MERGER AGREEMENT
                 TO EXTEND TERM FOR AN ADDITIONAL SIX MONTHS

Columbus, Ohio, and Dallas, Dec. 16, 1999 -- American Electric Power (NYSE:
AEP) and Central and South West Corp. (NYSE: CSR) have mutually agreed to
amend the agreement for the pending merger of the two companies to extend its
term.  This will allow additional time to satisfy the closing conditions
contained in the agreement.

This amendment to the merger agreement, approved by the boards of directors
of each company, requires that AEP and CSW gain final approvals before June
30, 2000.  The original merger agreement listed a Dec. 31, 1999 deadline.

The merger has already received approval from state regulatory commissions in
Arkansas, Louisiana, Oklahoma and Texas, the four states within CSW's service
territory. In addition, the Nuclear Regulatory Commission has approved a
license transfer application for the transfer of control of CSW subsidiary
Central Power and Light's South Texas Nuclear Plant.

The merger requires additional approvals by the Federal Energy Regulatory
Commission (FERC), the Securities and Exchange Commission (SEC) and clearance
by the Department of Justice under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976.  The administrative law judge who presided over the
FERC merger hearing filed an initial decision with the commission on Nov. 23
that found the AEP-CSW merger to be in the public interest. The FERC
indicated it will act on the merger no later than February or March 2000.
The SEC review will follow the FERC's action.

Central and South West Corp. is a global, diversified public utility holding
company based in Dallas. CSW owns four electric operating subsidiaries
serving 1.7 million customers in Texas, Oklahoma, Louisiana and Arkansas; a
regional electricity company in the United Kingdom; other international
energy operations and non-utility subsidiaries involved in energy-related
investments, telecommunications, energy efficiency and financial transactions.

AEP, a global energy company, is one of the United State' largest
investor-owned utilities, providing energy to 3 million customers in Indiana,
Kentucky, Michigan, Ohio, Tennessee, Virginia and West Virginia. AEP has
holdings in the United States, the United Kingdom, China and Australia.
Wholly owned subsidiaries provide power engineering, energy consulting and
energy management services around the world. The company is based in
Columbus, Ohio.

                               AMENDMENT No. 1
                                      TO
                         AGREEMENT AND PLAN OF MERGER

            This  Amendment  No. 1, dated as of December 31, 1999,  amends the
Agreement  and Plan of Merger as of December  21,  1997 by and among  American
Electric  Power  Company,  Inc.,  a  New  York  corporation  ("AEP"),  Augusta
Acquisition Corporation,  a Delaware corporation and a wholly owned subsidiary
of AEP  ("Augusta"),  and  Central  and South  West  Corporation,  a  Delaware
corporation  (the  "Company").  All Orders  necessary for the  consummation of
the Merger have not been obtained.

            The Board of Directors  of the Company,  the Board of Directors of
AEP,  and  the  Board  of  Directors  of  Augusta  have  determined  that  the
Termination  Date of December  31, 1999  provided in  Paragraph  9.1(f) of the
Merger  Agreement  should be extended upon the terms and  conditions set forth
herein.

            NOW  THEREFORE,   in   consideration  of  the  foregoing  and  the
respective  agreements  set forth in this  Amendment No. l, the parties hereto
agree as follows:

             1.   Paragraph  9.1(f) of the Merger  Agreement is hereby amended
                  so that,  as  amended,  it  shall  read in its  entirety  as
                  follows.

                        "(f.)  Termination  Date By either AEP or the Company,
                        by written  notice to the other,  if the Merger  shall
                        not have been  consummated  on or before June 30, 2000
                        ('Termination Date')."

              2.   The Merger  shall be  consummated  pursuant to Article 2 of
                  the  Merger  Agreement   provided  that  on  or  before  the
                  Effective  Date  all  closing  conditions  set  forth in the
                  Merger  Agreement shall be satisfied or, if permitted by the
                  Merger  Agreement,  waived in a writing given  subsequent to
                  the date of this Amendment No. 1.

              3.   This  Amendment  No. 1 is not and shall not be deemed to be
                  a waiver of any  rights or a release of any  obligations  of
                  any of the  parties to the Merger  Agreement  whether  based
                  upon  events,  facts or  conditions  occurring  or  existing
                  before or after the date hereof.

              4.   Capitalized  terms  shall  have  the same  meaning  in this
                  Amendment No. 1 as in the Merger Agreement.

            IN WITNESS  WHEREOF,  each of the  parties  hereto has caused this
Amendment  No. 1 to be  executed  as of the date  first  written  above by the
respective duly authorized officers thereunto duly authorized.
