Explanation of Responses:

1. Balance includes 195 shares acquired on March 9. 2018 through automatic dividend reinvestment.

2. Phantom stock units (which are in the form of deferred stock units) converted from the legacy Constellation Energy Group (CEG) Directors Deferred Compensation Plan to phantom units of Exelon common stock at the rate of 0.93 Exelon units for each unit of CEG. Units will be settled in cash on a 1 for 1 basis upon the termination of the reporting person's service on the Exelon board of directors. Balance updated to reflect additional stock units credited to the account through the dividend reinvestment feature of the plan.

3. Balance includes 257 shares acquired on March 9, 2018 through automatic dividend reinvestment.

4. Phantom share equivalents acquired through regular periodic contributions of deferred board compensation and the reinvestment of dividend equivalents in reporting person's Exelon stock fund account under multi-fund, non-qualified deferred compensation plan. The unitized fund consists of Exelon common stock and short term investments and will be settled in cash upon the reporting person's separation from the board for any reason. The balance of such phantom share equivalents may fluctuate from time to time due to fluctuations in the fund composition.

5. Balance includes 200 share equivalents accrued on February 13, 2018 through automatic dividend reinvestment.
