        ----------------------------------

     OGE Energy Corp. announced, May 17, 1999, 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. 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. The
transaction  will be treated as a purchase for accounting  purposes.  OGE Energy
does not expect to recognize any goodwill associated with this transaction.

     Some of the matters discussed in this Form 8-K may contain  forward-looking
statements of OGE Energy that are subject to certain risks,  uncertainties,  and
