                       FERC Administrative Law Judge Finds
                        AEP-CSW Merger in Public Interest

Columbus, Ohio, and Dallas, Nov. 23, 1999 -- The pending merger between American
Electric  Power  (NYSE:  AEP) and Central and South West Corp.  (NYSE:  CSR) was
found to be in the public  interest by Judge Joseph R. Nacy, the  administrative
law judge who presided  over the Federal  Energy  Regulatory  Commission  (FERC)
merger hearing.

"This is great news and a very  significant  step toward the  completion  of our
merger," said E. Linn Draper Jr., AEP's chairman,  president and chief executive
officer.  "More than 100 parties  intervened  in this merger,  raising  numerous
issues.  Judge Nacy  reviewed  testimony  on every issue set for  hearing.  This
decision validates what we've been saying since we announced the merger.  It's a
good deal for the  consumers and for  competition,  as well as being a good deal
for the companies."

Nacy's decision,  announced today, determined that the merger is consistent with
the public  interest;  rates,  terms and  conditions of rate schedules are just,
reasonable and not otherwise  unlawful;  and the joint open access  transmission
tariff  providing  for  post-merger  transmission  ancillary  services  is just,
reasonable and not otherwise unlawful. The judge found that arguments of several
parties  that AEP should be  required  to join the  Midwest  Independent  System
Operator as a condition of the merger were "not convincing."

The merger  now goes to the full FERC,  which has said it will act no later than
February or March of next year.

"This has been a long race,  but we have now  reached the point where we can see
the finish line," said Dick Brooks, chairman and chief executive officer of CSW.
"Regulatory  commissions in the four states CSW serves have already approved the
merger. We've put in a lot of hard work and we still have work to do, but we are
looking  forward  to  gaining  the final  regulatory  approvals  so we can begin
combining  the  companies  and flowing  the many  benefits of this merger to our
customers."


The merger requires approvals by the FERC, the Federal Communications Commission
and the  Securities  and Exchange  Commission and clearance by the Department of
Justice under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976. Upon
completion  of the merger,  the new  company  will be called  American  Electric
Power.

AEP and CSW announced  their intention to merge on Dec. 22, 1997. The merger has
received  approval from state  regulatory  commissions  in Arkansas,  Louisiana,
Oklahoma and Texas, the four states within CSW's service territory.

AEP and CSW  reached a  settlement  with the FERC trial staff in which the staff
supports a finding that the merger will have no adverse effect on competition.

AEP  and  CSW  have  announced  settlement  agreements  with  the  International
Brotherhood  of  Electrical  Workers  (IBEW) and the  Utility  Workers  Union of
America  (UWUA)  resulting in the IBEW and UWUA local unions  withdrawing  their
opposition  to  completion  of the merger;  as well as with the Indiana  Utility
Regulatory  Commission  (IURC) resulting in Indiana  customers  receiving merger
benefits and  including a commitment by the IURC not to oppose the merger during
consideration  of the merger agreement by the FERC and the SEC. AEP and CSW also
have announced a settlement agreement with key parties in Kentucky that has been
approved by the  Kentucky  Public  Service  Commission,  as well as a settlement
agreement  with  the  Missouri   Public  Service   Commission   addressing  that
commission's  concerns  about the effect of the merger on retail  competition in
the state.  The Public  Utility  Commission of Ohio (PUCO) has notified the FERC
that the PUCO is no longer opposing the pending merger or seeking  conditions on
the merger.

Additionally,  AEP and CSW have reached  settlements with a variety of wholesale
customers who had  intervened  in federal  proceedings.  The Nuclear  Regulatory
Commission has approved a license  transfer  application  related to the merger.
CSW will request an extension of the license  transfer  from the NRC before year
end.
