      Actual results may differ materially due to the speed and nature of increased
      competition and deregulation in the electric utility industry, economic or
      weather conditions affecting future sales and margins, changes in markets for
      energy services, changing energy and commodity market prices, replacement power
      costs being higher than anticipated or inadequately hedged, maintenance costs
      being higher than anticipated, legislative and regulatory changes (including
      revised environmental requirements), and the legal and regulatory changes
      resulting from the implementation of the EPACT (including, but not limited
      to,
      the repeal of the PUHCA), the uncertainty of the timing and amounts of the
      capital expenditures needed to, among other things, implement the Air Quality
      Compliance Plan (including that such amounts could be higher than anticipated)

      initiatives), the anticipated benefits from voluntary pension plan
      contributions, the ability to improve electric commodity margins, the ability
      to

                Annual
                Report of FirstEnergy Solutions Corp.
Forward-Looking
      Statements:
This Form 8-K
      includes forward-looking statements based on information currently available
      to
      management. Such statements are subject to certain risks and uncertainties.
      These statements typically contain, but are not limited to, the terms
"anticipate," "potential," "expect," "believe," "estimate" and similar words.
      Actual results may differ materially due to the speed and nature of increased
      competition and deregulation in the electric utility industry, economic or
      weather conditions affecting future sales and margins, changes in markets for
      energy services, changing energy and commodity market prices, replacement power
      costs being higher than anticipated or inadequately hedged, maintenance costs
      being higher than anticipated, legislative and regulatory changes (including
      revised environmental requirements), and the legal and regulatory changes
      resulting from the implementation of the EPACT (including, but not limited
      to,
      the repeal of the PUHCA), the uncertainty of the timing and amounts of the
      capital expenditures needed to, among other things, implement the Air Quality
      Compliance Plan (including that such amounts could be higher than anticipated)
      or levels of emission reductions related to the Consent Decree resolving the
      New
      Source Review litigation, adverse regulatory or legal decisions and outcomes
      (including, but not limited to, the revocation of necessary licenses or
      operating permits, fines or other enforcement actions and remedies) of
      governmental investigations and oversight, including by the SEC and the NRC
      as
      disclosed in FirstEnergy's SEC filings, the continuing availability and
      operation of generating units, the ability of our generating units to continue
      to operate at, or near full capacity, the inability to accomplish or realize
      anticipated benefits from strategic goals (including employee workforce
      initiatives), the anticipated benefits from voluntary pension plan
      contributions, the ability to improve electric commodity margins, the ability
      to
      access the public securities and other capital markets and the cost of such
      capital, the successful structuring and completion of a potential sale and
      leaseback transaction for Bruce Mansfield Unit 1 currently under consideration
      by management,
the
      successful completion of the FirstEnergy share repurchase program announced
      March 2, 2007,
the risks and other factors discussed from time to time in
      FirstEnergy's SEC filings, and other similar factors. Also, a security rating is
      not a recommendation to buy, sell or hold securities, and it may be subject
      to
      revision or withdrawal at any time and each such rating should be evaluated
      independently of any other rating. FirstEnergy expressly disclaims any current
      intention to update any forward-looking statements contained herein as a result
      of new information, future events, or otherwise.
