JPM’s obligation to purchase the PCRBs is not conditioned upon its ability to successfully reoffer them. As of the applicable settlement date, each series of PCRBs will be converted to the interest rate mode, bear interest from such date at the fixed rate per annum and be subject to mandatory purchase on the mandatory purchase date all as specified above. In addition, each series of PCRBs is, or will be as of the settlement date, secured by a like principal amount of first mortgage bonds of, as applicable, FG or NG issued under, in the case of FG, its Open-End Mortgage, General Mortgage Indenture and Deed of Trust, dated as of June 19, 2008, as amended and supplemented, to The Bank of New York Mellon Trust Company, N.A. (BNYMTC), as trustee, and, in the case of NG, its Open-End Mortgage, General Mortgage Indenture and Deed of Trust, dated as of June 1, 2009, as amended and supplemented, to BNYMTC, as trustee.

FES' debt obligations are generally guaranteed by FG and NG and FES guarantees the debt obligations of each of FG and NG. Accordingly, present and future holders of indebtedness of FES, FG and NG would have claims against each of FES, FG and NG, regardless of whether their primary obligor is FES, FG or NG.

the uncertainties associated with the deactivation of certain older regulated and competitive fossil units, including the impact on vendor commitments, such as long-term fuel and transportation agreements, and as it relates to the reliability of the transmission grid, the timing thereof; the impact of other future changes to the operational status or availability of our generating units and any capacity performance charges associated with unit unavailability; adverse regulatory or legal decisions and outcomes with respect to our nuclear operations (including, but not limited to, the revocation or non-renewal of necessary licenses, approvals or operating permits by the Nuclear Regulatory Commission or as a result of the incident at Japan's Fukushima Daiichi Nuclear Plant);

our ability to improve electric commodity margins and the impact of, among other factors, the increased cost of fuel and fuel transportation on such margins; changing market conditions that could affect the measurement of certain liabilities and the value of assets held in our Nuclear Decommissioning Trusts, pension trusts and other trust funds, and cause us and/or our subsidiaries to make additional contributions sooner, or in amounts that are larger than currently anticipated; the impact of changes to material accounting policies; the ability to access the public securities and other capital and credit markets in accordance with our financial plans, the cost of such capital and overall condition of the capital and credit markets affecting us and our subsidiaries;

Dividends declared from time to time on

FirstEnergy Corp.'s common stock during any period may in the aggregate vary from prior periods due to circumstances considered by FirstEnergy Corp.'s Board of Directors at the time of the actual declarations. A security rating is not a recommendation to buy or hold securities and is subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating.

New factors emerge from time to time, and it is not possible for management to predict all such factors, nor assess the impact of any such factor on our business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statements. FirstEnergy expressly disclaims any current intention to update, except as required by law, any forward-looking statements contained herein as a result of new information, future events or otherwise.
