           Arkansas Public Service Commission Approves Regulatory Plan
      On Merger Between American Electric Power and Central and South West

Columbus,  Ohio, and Dallas, Texas (Dec. 22, 1998) - The Arkansas Public Service
Commission  (APSC)  on Dec.  17  issued a final  order  granting  approval  of a
stipulated  agreement related to the proposed merger regulatory plan of American
Electric Power  Company,  Inc.  ("AEP")  [NYSE:  AEP] and Central and South West
Corporation  ("CSW")  [NYSE:  CSR].  CSW is the parent  company of  Southwestern
Electric Power Company (SWEPCO) SWEPCO serves portions of East Texas,  Northwest
Louisiana and West  Arkansas,  including  Fayetteville,  Booneville,  Rogers and
Eureka Springs.

Arkansas is the first state  jurisdiction to approve the proposed merger between
AEP and CSW. The APSC in August  approved the merger  between the two companies,
subject to any findings issued during the review of the proposed regulatory plan
for sharing of merger benefits in Arkansas.

The Arkansas  regulatory  plan is the result of a settlement  between the merger
applicants  and the  APSC  general  staff.  In  November,  AEP,  CSW and  SWEPCO
announced a settlement with the APSC general staff on the merger regulatory plan
related to the proposed merger.  The settlement calls for SWEPCO to reduce rates
through a net merger savings rider for its Arkansas retail  customers by amounts
totaling approximately $6 million over the five-year period following completion
of the merger. The parties filed the settlement with the APSC on Nov. 3.

The APSC  order  notes  the  possibility  of  decisions  in other  jurisdictions
adversely affecting  provisions of the Arkansas  settlement.  Consequently,  the
APSC approval is conditioned on its  consideration  of approval of the merger at
other state and federal regulatory bodies.

Richard E. Munczinski,  senior vice president - corporate planning and budgeting
for AEP,  noted that he was  "pleased  that we were able to reach  agreement  in
Arkansas so that  SWEPCO's  customers  can enjoy the  benefits  of the  merger."
Munczinski  said  AEP and CSW  will  continue  settlement  discussions  with the
Federal Energy Regulatory Commission, other regulatory bodies and intervenors in
the  various  merger  proceedings.   The  two  companies  already  have  reached
settlements with several groups in Texas and the Nuclear  Regulatory  Commission
has approved the license transfer  application  filed by CSW's Central Power and
Light Company subsidiary regarding the South Texas Project nuclear power plant.

"We have now received two approvals related to our merger," Munczinski said. "We
continue to be encouraged by the positive  progress we have been able to make in
the state of Texas. We are also pleased with the cooperation we have received in
other jurisdictions to assure that the merger is considered expeditiously."

In  Texas,  the  companies'  settlement-in-principle  with the  Office of Public
Utility  Counsel and the  Steering  Committee  of the cities of McAllen,  Corpus
Christi,  Victoria,  Abilene,  Big Lake,  Vernon  and  Paducah  would  result in
combined rate  reductions  totaling  approximately  $180 million over a six-year
period  following  completion of the merger for Texas customers of the three CSW
Texas  electric  operating  companies.  If approved by the city councils and the
Public Utility  Commission of Texas,  the settlement  will resolve all issues of
the signing parties.

"We expect to  continue  to make  progress  in the  remaining  federal and state
filings," Munczinski added.

The  companies   announced  a  definitive   merger  agreement  for  a  tax-free,
stock-for-stock transaction on Dec. 22, 1997. AEP and CSW jointly filed with the
FERC on April 30, 1998 for approval of their proposed merger. The companies also
have filed  applications  seeking  approval of the merger with the  Arkansas and
Texas commissions, as well as the Oklahoma Corporation Commission, the Louisiana
Public  Service  Commission,  the Federal Energy  Regulatory  Commission and the
Securities  and Exchange  Commission.  The companies  plan to make the final two
filings  associated with approval of the merger with the Federal  Communications
Commission and the Department of Justice in the near future.

Central and South West  Corporation  is a Dallas-based  public  utility  holding
company  that owns four U.S.  electric  utility  subsidiaries  with 1.7  million
customers,  a regional  electricity  company serving 2 million  customers in the

investments  as well  as  subsidiaries  that  offer  telecommunications,  energy
efficiency and financial transactions.
