Item 5.  Other Events

              On May 8, 2002, FirstEnergy Corp. completed the sale of a 79.9
     percent interest in its Avon Energy Partners Holdings subsidiary to Aquila,
     Inc. (formerly UtiliCorp United) in exchange for a $150 million payment at
     closing and six annual payments of $19 million, guaranteed by Aquila at the
     holding company level, commencing on the first anniversary of the closing.
     As previously filed on Form 8-K dated March 18, 2002, Avon's debt of
     approximately $1.7 billion, which is non-recourse to FirstEnergy, would no
     longer be included on FirstEnergy's consolidated balance sheet. Aquila and
     FirstEnergy together will own all of the outstanding shares of Avon through
     a jointly owned subsidiary, with each company having a 50-percent voting
     interest. FirstEnergy's 20.1 percent economic interest in the joint venture
     will be accounted for under the equity method of accounting.
