Item 5.  Other Events

     On March 15, 2002,  FirstEnergy  Corp.  finalized the terms of a previously
announced  agreement through which Aquila, Inc. (formerly UtiliCorp United) will
acquire a 79.9  percent  economic  interest in  FirstEnergy's  wholly owned Avon
Energy  Partners   Holdings   subsidiary,   the  holding  company  for  Midlands
Electricity  plc,  for a  purchase  price of $264  million.  As a result of this
transaction, 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.  The  transaction is subject to the receipt of all applicable  regulatory
approvals.

     Aquila and FirstEnergy  together will own all of the outstanding  shares of
Avon Energy  Partners  Holdings  through a jointly owned  subsidiary,  with each
company  having a 50-percent  voting  interest.  Midlands  Electricity's  assets
include its  38,000-mile  electric  distribution  network,  an investment in the
1,875-megawatt  Teesside  Power  generating  plant in the  United  Kingdom,  and
investments in other energy businesses.

     Under the revised  terms of the  Purchase and Sale  Agreement,  Aquila will
acquire a 79.9% economic interest in Avon 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.
FirstEnergy  will retain  ownership  of the  remaining  20.1%  interest in Avon.
FirstEnergy  and Aquila  will form a new joint  venture  entity  with Class "A",
Class "B" and Class "C" shares. The A Shares,  owned by Aquila, will represent a
79.9% economic interest and have a 50% voting interest in the entity.  The B and
C Shares,  both owned by FirstEnergy,  will represent a 20.1% economic  interest
and the B shares will have a 50% voting interest in the entity.

     Terms of the  agreement  provide  that Aquila has  certain  rights of first
refusal with respect to FirstEnergy's transfer of its ownership interest.

     The  restructured  Purchase  and  Sale  Agreement  provides  an  acceptable
financial  outcome for  FirstEnergy.  FirstEnergy  estimates  that the  dilutive
earnings impact of the revised sale terms is approximately  $0.11 per share, the
same as it was in the previously  announced agreement.  FirstEnergy's  estimated
income  associated  with its 20.1% ownership is expected to offset the reduction
in securities  retirements due to the reduced up-front cash sale proceeds.  More
importantly,  the restructured sale allows FirstEnergy to largely accomplish its
strategic  objectives of divesting non-core assets and strengthening its balance
sheet through debt retirements.
