Explanation of Responses:

( 1 )Restricted stock unit (RSU) award granted under the Exelon LTIP. Award vests in 1/3 increments at the January or February meeting of the Exelon Compensation Committee with each RSU representing the right to receive one share of Exelon common stock upon vesting. The award accrues quarterly dividend equivalents in the form of additional RSUs representing common stock dividends as approved by the Board, which vest on the same schedule as the underlying RSU award. ( 2 )Phantom share equivalents held in the reporting person's Exelon stock fund account that is part of a multi-fund, non-qualified deferred compensation plan. The stock fund is a unitized fund that consists of both Exelon common stock and short-term liquid investments. Units of the fund are acquired through quarter-end contributions and dividend reinvestment and will be settled for cash upon the termination of the reporting person. The balance of phantom share equivalents may fluctuate due to changes in the value of the fund units.
