Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The amount listed in Table II represents 50% of the original RSUP17 award, which was the minimum amount guaranteed to be paid out upon vesting. The award vested on March 5, 2015 and because the performance targets were achieved, the award was paid out at a performance rate of 100%. The shares coded "A" represent the portion attributable to this performance adjustment. The shares coded "F" were withheld to cover income tax obligations associated with the payout.
(2) 1 for 1
(3) Upon the vesting of restricted stock units granted to the reporting person on March 5, 2012, the reporting person later made an election to defer the receipt of 706 shares of common stock and received instead 706 shares of phantom stock pursuant to the Executive Deferred Compensation Plan. As a result, the reporting person is reporting the disposition of 706 shares of common stock in exchange for an equal number of shares of phantom stock.
(4) Balance includes shares acquired through dividend reinvestments.
(5) FE's 401(k) Plan includes a unitized fund invested in FE stock, in which the reporting person may invest, which includes dividend reinvestment and company match features. The number of shares reported as indirectly held in the 401(k) Plan in this row is an estimate of the number of shares of FE's common stock held in the unitized stock fund and allocated to the reporting person's account as of December 31, 2014.
(6) This transaction reflects the vesting and deferral of RSUP17 to phantom stock.
(7) This holding reflects the extension and vesting of phantom stock to retirement or other termination of employment under arrangements approved by the Compensation Committee.
(8) Includes stock units acquired through dividend reinvestment.
