OGE ENERGY CORP.'S ENOGEX SUBSIDIARY
TO ACQUIRE TRANSOK LLC

     OKLAHOMA  CITY - OGE Energy  Corp.  (NYSE:  OGE)  announced  today that its
subsidiary,  Enogex Inc.,  will acquire  Transok LLC, a gatherer,  processor and
transporter  of  natural  gas in  Oklahoma.  The  seller is Tejas  Energy LLC of
Houston, an affiliate of Shell Oil Company.

     Tejas had  previously  announced  plans to sell  Transok  and has  accepted
Enogex's  offer of $701 million,  which  includes  assumption of $173 million of
long-term  debt. OGE Energy's  board of directors has approved the  acquisition,
which is subject to regulatory review under the Hart-Scott-Rodino Act of 1976.

     "This  acquisition  provides  OGE Energy with  excellent  opportunities  to
create  long-term  value and is  consistent  with our  strategy of  disciplined,
asset-based  growth around our core  businesses -- electricity and natural gas,"
said Steven E. Moore, chairman, president, and CEO of OGE Energy. "As the energy
markets here and across the country move through the process of deregulation, we
look forward to competing in those markets with the  integration of Transok into
our Enogex natural gas and energy services businesses.  Enogex and Transok are a
great fit and the potential in this combination is exciting for our companies."

     Enogex Inc., a subsidiary  of OGE Energy,  is a  non-regulated  natural gas
gathering, processing,  transportation,  production, and energy services company
with principal pipeline operations in Oklahoma,  Arkansas, and Texas. OGE Energy
also is the parent of Oklahoma Gas





and Electric Company, a regulated electric utility with nearly 700,000 customers
in Oklahoma and western Arkansas.

     Integration of the Transok system with the Enogex network of pipelines will
bring the total to about  10,000  miles of pipe with the  capacity to  transport
more  than 3 billion  cubic  feet of gas per day to a number  of  end-users  and
pipelines. Combined natural gas storage capacity will be nearly 23 billion cubic
feet. Together, the companies have interests in 15 gas processing plants.

     "These two systems  complement  one another  quite well," Moore said.  "The
integrated  systems,  from the gas  wellheads  to the  major  pipeline  delivery
points,  stretch from the Texas Panhandle across half of Oklahoma's 77 counties,
through Arkansas all the way to eastern Missouri.  Oklahoma is the third-leading
gas producing state in the country, and the combined  Enogex/Transok system will
be one of the state's  major gas  gathering and  transportation  systems.  We're
excited about the possibilities."

     The  transaction is expected to be slightly  dilutive to OGE Energy Corp.'s
earnings in 1999 due primarily to  transaction-related  costs,  and accretive to
earnings in 2000. Lehman Brothers is Enogex's  financial adviser for the Transok
acquisition. Tejas is represented by Merrill Lynch.

     Some  of  the  matters   discussed   in  this  news   release  may  contain
forward-looking  statements  of OGE Energy  that are  subject to certain  risks,
uncertainties, and assumptions. Actual results may vary materially. Factors that
could cause actual results to differ materially include, but are not limited to:
general  economic  conditions,  including their impact on capital




expenditures;  business conditions in the energy industry;  competitive factors;
unusual  weather;  regulatory  decisions  and other risk  factors  listed in OGE
Energy's Form 10-K for the year ended Dec. 31, 1998 and other factors  described
from  time  to time in OGE  Energy's  reports  to the  Securities  and  Exchange
Commission.
