Explanation of Responses:
(1)	Balance includes 160 shares acquired on June 9, 2017 through automatic dividend reinvestment.
(2)	Phantom stock units (which are in the form of deferred stock units) which will become payable in cash on a 1 for 1 basis upon the termination of the reporting person's service on the Exelon board of directors.
(3)	Balance includes 243 shares acquired on June 9, 2017 through automatic dividend reinvestment.
(4)	Phantom share equivalents representing units held in the Exelon stock fund in a multi-fund, non-qualified deferred compensation plan. The Exelon stock fund is a unitized fund that consists of Exelon common stock and short term investments. Units of the fund will be settled upon the reporting person's separation from the board for any reason. Units will be settled in cash. Units are acquired through regular periodic contributions of deferred board compensation and the reinvestment of dividend equivalents. The balance of phantom share equivalents may fluctuate from time to time due to fluctuations in the fund composition.
(5)	Balance includes 179 share equivalents accrued on May 11, 2017 through automatic dividend reinvestment.
