Form of Exelon Corporation Unfunded Deferred Compensation Plan

 Exhibit 10.3 

Exelon Corporation 

Unfunded Deferred Compensation Plan for Directors 

(Amended and Restated Effective March 12, 2012) 

The purpose of this Unfunded Deferred Compensation Plan for Directors (the “Plan”) is to permit Directors of Exelon Corporation
(“Exelon”) to elect to defer receipt of directors’ fees. The Plan as set forth herein is an amendment and restatement of the Plan as originally adopted effective October 20, 2000 and previously amended and restated as of January 1,
2009 and January 1, 2011, and is a successor to the PECO Energy Company Unfunded Deferred Compensation Plan for Directors (the “Prior Plan”). 

1. Administration. The Plan shall be administered by the Corporate Secretary of Exelon or his or her designee (the
“Secretary”), or such other individual or individuals as designated by the Board of Directors of Exelon (the “Exelon Board”). The Secretary shall interpret the Plan and establish such rules and regulations of plan
administration that he or she deems appropriate. The cost of plan administration shall be paid by Exelon and its participating subsidiaries, and shall not be charged against the deferred accounts of Plan participants. 

2. Eligibility. All Directors of Exelon (other than full-time employees of Exelon or its subsidiaries) shall be eligible to
participate in the Plan. Effective as of January 1, 2011, all Directors of Commonwealth Edison Company (“ComEd”) and PECO Energy Company (“PECO”) who are not full-time employees of Exelon or its subsidiaries shall also be
eligible to participate in the Plan. In addition, effective as of March 12, 2012, all Directors of Baltimore Gas and Electric Company (“BGE”) who are not full-time employees of Exelon or its subsidiaries shall also be eligible to
participate in the Plan. 
 3. Deferrals. (a) Prior to the first day of each calendar year, each eligible Director may
elect in writing to defer the receipt of all or a portion of his or her directors’ fees 

 
earned with respect to his or her service on the board of directors of Exelon, ComEd, PECO and/or BGE (each such board of directors, a “Board”) for such calendar year, by filing a
written Director’s deferral agreement form with the Secretary with respect to each such Board on which the Director serves. A Director who first becomes eligible to participate in the Plan after the first day of any calendar year shall be
permitted to make the election described in this Section 3 not later than 30 days after becoming eligible to participate in the Plan, and such election shall apply only to directors’ fees earned during the remainder of such calendar year. In
all events, each deferral election made under this Plan shall apply only to fees earned after the date of such election. Deferred amounts under the Plan, together with deferred amounts and attributable earnings under the Prior Plan, shall be
credited to a deferral account in the participant’s name (“Deferral Account”) for later distribution. Each participant’s Deferral Account shall be a bookkeeping entry only, and none of Exelon, ComEd, PECO or BGE shall be required
to fund the Deferral Account. Any assets that may be held to fund a Deferral Account shall at all times remain unrestricted assets of Exelon, ComEd, PECO or BGE in its corporate capacity and not as a fiduciary, and shall be subject to the
claims of its general creditors. Pending distribution, each participant’s Deferral Account shall be credited with earnings or interest as provided in Section 3(b). 

(b) (1) For purposes of measuring the earnings or losses credited to a participant’s Deferral Account, the participant may select, from
among the investment funds available from time to time under the Exelon Corporation Employee Savings Plan (the “Savings Plan”), the investment funds in which all or part of his or her Deferral Account shall be deemed to be invested. 

(2) The participant shall make an investment designation in the form and manner prescribed by the Secretary, which shall remain
effective until another valid 

  
 -2- 

 
designation has been made by the participant as herein provided. The Secretary may, but need not, permit separate investment designations with respect to amounts attributable to fees earned
with respect to service on each Board. The participant may amend his or her investment designation at such times and in such manner as prescribed by the Secretary. A timely change to the participant’s investment designation shall
become effective as soon as administratively practicable after such designation is submitted. 
 (3) The investment funds deemed to be
made available to the participant, and any limitation on the maximum or minimum percentages of the participant’s Deferral Account that may be deemed to be invested in any particular fund, shall be the same as available or in effect from time to
time under the Savings Plan. 
 (4) Except as provided below, the participant’s Deferral Account shall be deemed to be invested
in accordance with his or her investment designations, and the Deferral Account shall be credited with earnings (or losses) as if invested as directed by the participant. 

To the extent that the participant does not furnish complete investment instructions, then the Deferral Account shall be deemed invested in
the default investment fund then in effect under the Savings Plan. The Deferral Accounts maintained pursuant to the Plan are for bookkeeping purposes only and Exelon is under no obligation to invest such amounts. 

Exelon shall provide a statement to each participant not less frequently than annually showing such information as is appropriate, including
the aggregate amount in his or her Deferral Account, as of a reasonably current date. 
 4. Distributions. (a) The amount
credited to a participant’s Deferral Account with respect to his or her participation on each Board shall be distributed to the participant in, or beginning in, April of the first year beginning after the occurrence of one of the following

  
 -3- 

 
distribution events, as the participant shall direct in his or her Benefit Distribution Election Form: (i) the participant’s separation from service, within the meaning of Section 409A
of the Internal Revenue Code of 1986, as amended (the “Code”), as a Director of Exelon, ComEd, PECO, BGE and their affiliates, (ii) the participant’s 65th birthday or (iii) the participant’s 72nd birthday. Distributions shall be paid in a lump sum payment or in annual installments over a period of up to 10 years, as the participant shall direct in his or her Benefit Distribution Election
Form. Each installment payment shall be determined by multiplying the balance remaining to the credit of the Deferral Account as of March 31 of such year (including earnings or interest credited under Section 3) by a fraction, the numerator of
which is “1” and the denominator of which is the number of years (including the current year) for which payments are yet to be made. Any unpaid balance in the Deferral Account shall be credited with earnings or interest as provided in
Section 3. In the event a Director who has elected a distribution event based on his or her 65th or 72nd birthday continues to serve as a
Director after the date such distributions commence, then in the year prior to the year in which such distributions commence such Director shall file a new Benefit Distribution Election Form governing any amounts credited to his or her Deferral
Account after the date such distributions commence. If the Director does not file such new Benefit Distribution Election Form, then the Director shall be deemed to have elected to receive a lump sum distribution of any such amounts upon the
Director’s separation from service. 
 (b) Except as permitted under Section 4(c) or 4(d), each Director must submit a Benefit
Distribution Election Form for amounts attributable to fees earned with respect to service on a Board at the time such Director makes his or her initial deferral election under the Plan with respect to his or her service on such Board (provided that
a Director who participated in the Plan prior to January 1, 2009 and had not commenced distributions must have submitted such form not later than December 31, 2008). If a Director does not submit a Benefit Distribution Election Form

  
 -4- 

 
during this period, then such Director shall be deemed to have elected to receive the portion of his or her Account attributable to fees earned for service on such Board in the form of
installments payments over a period of ten years upon the Director’s separation from service. 
 (c) Notwithstanding Sections 4(a) and
4(b), each participant who had not commenced and was not scheduled to commence the receipt of distributions under the Plan on or before December 31, 2007 was permitted to submit a Benefit Distribution Election Form on or before June 30, 2007 which
provided for the payment of such participant’s Deferral Account (i) at any of the times and in any of the forms permitted under Section 4(a) of the Plan or (ii) in a lump sum payment in the first quarter of 2008; provided that such election did
not cause any payment to be made in 2007 and did not apply to any payment that otherwise would be paid in 2007. This special election right was intended to comply with the transition rule set forth in IRS Notice 2005-1, Q&A-19(c), and
extended in the preamble to regulations proposed under Section 409A of the Code and IRS Notice 2006-79, which permits participants in deferred compensation plans to change the date on which deferred compensation is payable. 

(d) A Director may elect to change the time and/or method of his or her distributions payable under the Plan in accordance with procedures
prescribed by the Secretary; provided that, in accordance with Section 409A of the Code, any such change in a distribution election (i) shall not be effective until 12 months after it is submitted to the Secretary, (ii) must be submitted to the
Secretary at least 12 months prior to the date on which such distributions were previously scheduled to commence and (iii) must provide for distributions to commence at least five years after the date on which such distributions were previously
scheduled to commence. No more than one such election change shall be permissible with respect to the portion of a Director’s account attributable to service with any Board. 

  
 -5- 

 5. Death Benefits. Each participant shall designate a beneficiary or beneficiaries to
receive any remaining amounts payable from his or her Deferral Account after the participant’s death. The beneficiaries, and any priority or allocation between them, shall be designated in the manner specified by the Secretary. If a participant
dies before the entire balance in his or her Deferral Account has been paid out, the remaining balance shall be paid to the beneficiary in a lump sum upon the participant’s death. If the participant is not survived by a designated beneficiary,
the participant’s beneficiary shall be the participant’s spouse, if living, or otherwise, the participant’s estate. If a beneficiary survives the participant but dies before the entire balance payable to him or her has been
distributed, any remaining balance shall be paid to the beneficiary’s estate in a lump sum. In the absence of contrary proof, the participant shall be deemed to have survived any designated beneficiary. A participant may change his or
her beneficiary designation under this Section at any time until his or her death by filing a written beneficiary designation with the Secretary, in the manner specified by the Secretary. 

6. Unforeseeable Financial Emergency. The Secretary may, in his or her discretion, direct that a participant be paid an amount in cash
(not in excess of the balance of his or her Deferral Account) sufficient to meet an unforeseeable emergency. An “unforeseeable emergency” means (i) a severe financial hardship to a Director resulting from an illness or accident of the
Director, or the spouse or a dependent (as defined in Section 152(a) of the Code) of the Director, (ii) the loss of a Director’s property due to casualty or (iii) such other similar extraordinary and unforeseeable circumstances arising as a
result of events beyond the control of the Director, within the meaning of Section 409A of the Code. A Director’s written request for such a payment shall describe the circumstances which the Director believes justify the payment and an
estimate of the amount necessary to eliminate the unforeseeable emergency. An immediate payment to satisfy an unforeseeable emergency will be made only to the extent necessary to satisfy the emergency need,

  
 -6- 

 
plus an amount necessary to pay any taxes reasonably anticipated as a result of such payment, and will not be made to the extent the need is or may be relieved through reimbursement or
compensation, by insurance or otherwise or by liquidation of the Director’s assets (to the extent such liquidation itself would not cause severe financial hardship). Any payment from a Director’s Deferral Account on account of an
unforeseeable emergency shall be deemed to cancel any Deferral Election of the Director then in effect and the Director shall not be permitted to participate in the Plan until the next following calendar year. 

7. No Assignment or Alienation of Benefits. Except as hereinafter provided with respect to a domestic relations order, a
participant’s Deferral Account may not be voluntarily or involuntarily assigned or alienated. In cases of marital dispute, Exelon will observe the terms of the Plan unless and until ordered to do otherwise pursuant to a domestic relations
order, as defined in Section 414(p)(1)(B) of the Code. As a condition of participation, a participant agrees to hold Exelon harmless from any claim that arises out of Exelon’s obeying the terms of a domestic relations order, whether
such order effects a judgment of such court or is issued to enforce a judgment or order of another court. 
 8. Amendment or
Termination. The Plan may be altered, amended, suspended, or terminated at any time by the Exelon Board, provided that, except as otherwise provided herein or as permitted under Section 409A of the Code, no such action shall result in the
distribution of amounts credited to the Deferral Accounts of any participant in any manner other than is provided in the Plan, nor shall such action reduce the availability of amounts previously deferred. To the extent permitted by Section
409A, the Exelon Board may, in its discretion, terminate the Plan with respect to Exelon, ComEd, PECO and/or BGE and accelerate the payment of all Deferral Accounts to the extent related to service on the Board for which the Plan is terminated: 

(a) within 12 months of a corporate dissolution taxed under Section 331 of the Code, or with the approval of a bankruptcy court pursuant to 11
U.S.C. §503(b)(1)(A), provided that the payments with respect to each such Deferral Account are included in the Director’s gross income in the later of (i) the calendar year in which the Plan termination occurs or (ii) the first calendar
year in which the payments are administratively practicable; 

  
 -7- 

 (b) in connection with a “change in control event,” as defined in, and to the extent
permitted under, Treasury regulations promulgated under Section 409A of the Code or 
 (c) upon any other termination event permitted
under Section 409A of the Code. 
 9. Compliance With Section 409A of the Code. The Plan is intended to comply with the
provisions of Section 409A of the Code, and shall be interpreted and construed accordingly. Exelon shall have the discretion and authority to amend the Plan at any time to satisfy any requirements of Section 409A of the Code or guidance
provided by the U.S. Treasury Department to the extent applicable to the Plan. 
 10. Governing Law. The Plan shall be governed
by the law of the Commonwealth of Pennsylvania to the extent not preempted by applicable federal law.

 Exhibit 10.21.1 

EXELON CORPORATION 

SENIOR MANAGEMENT 

SEVERANCE PLAN 
 (As
Amended and Restated) 

 EXELON CORPORATION 

SENIOR MANAGEMENT SEVERANCE PLAN 

(As Amended and Restated) 
  

	1.	PURPOSE OF THE PLAN 

 The Exelon Corporation Senior Management Severance Plan, as
amended and restated herein (the “Plan”), is effective as of November 1, 2015 (the “Effective Date”) except as otherwise specifically provided herein, and supersedes in its entirety all prior versions of the Plan
with respect to terminations of employment occurring any time on or after the Effective Date (or such other date as set forth herein). The Plan provides severance benefits to eligible executives of Exelon Corporation (“Exelon”) and
its subsidiaries of which Exelon owns at least 80% of the outstanding voting power that are designated by the Plan Administrator as participating employers in the Plan (Exelon and such subsidiaries jointly and severally referred to as the
“Company”) who submit a Notice of Termination or who are notified of their termination of employment on or after the Effective Date (or such other date as set forth herein), and to provide additional protection in the event of a
Change in Control of Exelon or an Imminent Control Change of Exelon. 
  

	2.	ELIGIBILITY 

  

	 	2.1.	Eligibility in General. Subject to the remaining provisions of this Section 2.1, eligibility to participate in the Plan is limited to each employee of the Company whose position is in Salary Band E09 (or
equivalent executive grade) or above (an “Executive”) who executes and returns to the Company by the later of 90 days after becoming an Executive, or 90 days after delivery thereof to the Executive, non-competition,
non-solicitation, confidential information and intellectual property covenants (“Restrictive Covenants”) which are acceptable to Exelon and are either substantially in the form attached hereto and made a part hereof as Exhibit I (as
may be modified from time to time by Exelon in its sole discretion) or set forth in another agreement between the Company and the Executive. Notwithstanding any provision of the Plan to the contrary, eligibility for benefits under the Plan shall be
subject to the provisions of any agreement (including but not limited to an offer of employment or grant instrument) between an Executive and the Company providing that that such Executive would be ineligible for (or waives) all or a portion of the
benefits under the Plan or “change in control” benefits in the event of a termination of employment, or under which the Executive had agreed, prior to the Applicable Trigger Date, to terminate his or her employment. 

 

	 	2.2.	 Eligibility Under Section 4. Subject to Section 2.1, each Executive shall be eligible for the benefits provided under
Section 4 hereof in the event such Executive has a Termination of Employment; provided, however, that any Executive whose Termination of Employment is covered under Section 5 hereof or a change in control agreement entered into between
such Executive and the Company (an “Individual Change in Control Agreement”), or who is an interim employee separating under the change in control provisions of another severance

	 	
plan, shall not be eligible for benefits under Section 4, except as expressly provided in Section 5 or such Individual Change in Control Agreement (which expressly refers to the benefits under
Section 4 of this Plan). 

  

	 	2.3.	Eligibility Under Section 5. Eligibility for the benefits provided under Section 5 hereof due to a Termination of Employment during a Post-Change Period or an Imminent Control Change
Period shall be subject to Section 2.1, and shall be limited to persons who are Executives immediately prior to the Applicable Trigger Date and who are not subject to Individual Change in Control Agreements. 

 

	3.	PARTICIPATION 

 Each eligible Executive shall become a participant in the Plan
(“Participant”) upon his or her execution of a separation agreement with the Company in such form as the Company, in its sole discretion, shall require or permit (the “Severance Agreement”), provided such Severance
Agreement is executed not later than 45 days after the Executive’s Termination Date. Notwithstanding anything herein to the contrary, each Executive shall also be required to execute, not later than 45 days after the Executive’s
Termination Date, a waiver and release of claims against the Company (“Waiver and Release”) which is substantially in the form attached hereto and made a part hereof as Exhibit II, as may from time to time be modified by the Company
in its sole discretion. An Executive’s right to the payments and benefits under this Plan shall be contingent upon (a) Executive having timely executed and delivered to the Company the Severance Agreement, Waiver and Release and Restrictive
Covenants, (b) Executive not revoking the Waiver and Release and (c) Executive not violating any of Executive’s on-going obligations under the Plan, the Waiver and Release and the Restrictive Covenants. To the extent that the Company makes
payments and provides benefits to an Executive prior to receipt of the Waiver and Release and/or the expiration of the revocation period and the Executive either does not timely execute and deliver the Waiver and Release to the Company or revokes
the Waiver and Release in accordance with its terms, Executive shall pay to the Company within 10 days following the expiration of the 45-day consideration period or the date such release was revoked, a lump sum payment of all payments and the value
of all benefits received by Executive to date hereunder. 
  

	4.	BENEFITS 

 A Participant described in Section 2.2 shall be entitled to all Accrued
Obligations and, subject to Section 6, benefits pursuant to this Section 4 upon the Participant’s Termination of Employment. 
  

	 	4.1.	Severance Pay. 

  

	 	(a)	 In General. Each Participant other than a Participant described in Section 4.1(b) shall receive severance pay at a monthly rate equal to 1/12
of the sum of (a) the Participant’s annual base salary in effect as of the date of Termination of Employment, plus, if the Executive is a participant in the Annual Incentive Award Plan with respect to the year in which the Termination Date
occurs, (b) the Severance Incentive. Subject to Section 13.13 below, payment shall be made in regular payroll installments for the 

  
 2 

	 	
duration of the applicable Salary Continuation Period, as indicated below, commencing no later than the second paydate which occurs after the Participant’s Termination Date. Payment will be
made in accordance with the Company’s normal payroll practices, net of applicable taxes and other deductions. 

  

					
	Participant Level	  	Salary Continuation Period	  	 
			
	Senior Executive Management	  	24 months	  	
	Senior Vice Presidents of Exelon	  	18 months	  	
	Other Executives	  	15 months	  	

  

	 	(b)	Participants Employed for Less Than Two Years. Each Participant who has been continuously employed by the Company for less than twenty-four months as of the Participant’s Termination Date shall receive
severance pay at a monthly rate equal to 1/12 of the Participant’s annual base salary in effect as of the Termination Date. Subject to Section 13.13 below, payment shall be made in regular payroll installments for the duration of the applicable
Salary Continuation Period, as indicated below, commencing no later than the second paydate which occurs after the Participant’s Termination Date. Payment will be made in accordance with the Company’s normal payroll practices, net of
applicable taxes and other deductions. 

  

					
	Participant Level	  	Salary Continuation Period	  	 
		
	Senior Executive Management	  	18 months (12 months if employed < 12 months)
	Other Executives	  	12 months (6 months if employed < 12 months)

  

	 	4.2.	 Annual Incentive Awards. Each Participant who is a participant in the Annual Incentive Award Plan for the year in which the Termination
Date occurs shall receive an Annual Incentive which shall be prorated by multiplying the amount of such Annual Incentive by a fraction the numerator of which is the number of days elapsed during such year as of the Participant’s Termination
Date and the number of days in the year in which Termination Date occurs. Payment of Annual Incentives under this Section 4.2 shall be made in a lump sum net of applicable taxes and other deductions at the time awards under the Annual Incentive
Award Plan are paid to active employees for such performance period (but not later than March 15 of the year following the last day of such performance period), and 

  
 3 

	 	
shall be considered a “short-term deferral” within the meaning of Section 409A of the Code. A Participant who is not a participant in the Annual Incentive Award Plan for the year in
which the Termination Date occurs shall not be entitled to an Annual Incentive, and the amount (if any) payable under any other Incentive Plan for such year shall be determined by the Company in its sole discretion. 

 

	 	4.3.	Stock Options. No Participant shall be entitled to participate in any new grants of Stock Options (as defined in Section 5.1(b)) made after such Participant’s notification of his or her Termination of
Employment. Except as provided below, any Stock Options previously granted to the Participant shall be exercisable only to the extent such Stock Options are exercisable as of the date of such Participant’s Termination Date and shall thereafter
be exercised in accordance with the provisions of the LTIP. Stock Options which remain unexercisable as of the Participant’s Termination Date shall be forfeited. Notwithstanding the preceding, if, as of the last day of the Salary Continuation
Period, such Participant has attained at least age 50 ( age 55 with respect to Stock Options granted on or after January 1, 2013) and completed at least 10 years of service as defined under the tax-qualified defined benefit plan maintained by Exelon
in which the Executive is a participant (the “Pension Plan”) or SERP, then any Stock Options granted to such Participant which have not become exercisable prior to the Participant’s Termination Date shall (i) become fully
vested, and (ii) remain exercisable until the fifth anniversary of the Termination Date or, if earlier, the option expiration date, provided that this Section 4.3 shall not limit the right of the Company to cancel the Stock Options in connection
with a corporate transaction pursuant to the terms of the LTIP. 

  

	 	4.4.	Other Awards. Awards of Performance Shares, Restricted Stock (as defined in Sections 5.1(c) and 5.1(d), respectively) and/or Cash Performance Awards, as applicable, shall be payable to a Participant solely
to the extent provided under the terms of such awards and the applicable plan under which such awards are granted; provided, however, that to the extent the Company determines that a Participant is a Specified Employee and that any such payment is
deferred compensation, each within the meaning of Section 409A of the Code, such payment shall not be made prior to the earlier to occur of (i) the six-month anniversary of the Termination Date or (ii) the date of the Participant’s death.

  

	 	4.5.	 Health Care Coverage. During the Salary Continuation Period, a Participant (and his or her dependents) shall be eligible to participate in
the health care plans under which they were covered immediately prior to his or her Termination of Employment, in accordance with and subject to the terms and conditions of such plans as in effect from time to time. The Participant’s out of
pocket costs (including premiums, deductibles and co-payments) for such coverage shall be the same as that in effect from time to time for active peer employees during such period. Coverage under this Paragraph 4.5 shall be provided for the
duration of the Salary Continuation Period in lieu of continuation coverage under Section 4980B of the Code and Section 601 to 609 of ERISA (“COBRA”) for the same period. At the end of the Salary Continuation Period, COBRA
continuation coverage may be elected for the remaining balance of the statutory coverage 

  
 4 

	 	
period, if any; provided, however that a Participant who, as of the last day of the Salary Continuation Period, has attained at least age 50 and completed at least 10 years of service (or who has
completed such other age and service requirement then in effect under the Exelon Corporation Severance Benefit Plan or any successor plan as of the relevant time set forth in such plan) under the terms of the Pension Plan (or who, pursuant to the
terms of an offer of employment or employment agreement or under any provision of the Pension Plan or SERP, is credited with a number of additional years of age and/or service that would enable such Participant to satisfy the above eligibility
requirements) shall be entitled to elect such Company group health care programs for retirees as are in effect as of the Termination Date and are applicable to such Participant by the programs’ eligibility terms and conditions as though such
Participant had attained such programs’ age and service requirements. The eligibility for coverage and availability of programs or plans, the amounts charged for coverage, and the other terms, conditions and limitations under the Company’s
group health care programs or plans shall remain subject to the Company’s right to amend, change or terminate such programs or plans at any time. 

  

	 	4.6.	SERP / Other Deferred Compensation. For purposes of the Participant’s SERP benefit, the Salary Continuation Period shall be taken into account as service solely for purposes of determining whether the
Participant is vested (i.e., 3 or 5 years of service) and, to the extent relevant under the Pension Plan covering the Participant, the amount of the Participant’s regular accrued benefit, but not for purposes of determining eligibility for
early retirement benefits (including any social security supplement) or any other purpose. In determining the amount of the Participant’s vested benefit, if any, the severance payments made under Section 4.1 shall be taken into account as
if such payments were normal base salary and incentive payments. Payment shall be made in accordance with the SERP and the Participant’s distribution election in effect thereunder as of the Termination Date (or, if no affirmative election is in
effect as of such date, the default election applicable to the Participant). All amounts previously deferred by, or accrued to the benefit of, such Participant under the Exelon Corporation Deferred Compensation Plan, the Exelon Corporation Stock
Deferral Plan or the Constellation Energy Group, Inc. Nonqualified Deferred Compensation Plan shall, to the extent vested, be paid in accordance with the Participant’s distribution election in effect thereunder as of the Termination Date (or,
if no affirmative election is in effect as of such date, the default election applicable to the Participant). 

  

	 	4.7.	Life Insurance and Disability Coverage. A Participant shall be eligible for continued coverage under the applicable basic life insurance and long term disability plans sponsored by the Company (or other
equivalent coverage or benefits) shall be extended to each Participant through the last day of the Salary Continuation Period applicable to such Participant on the same terms and subject to the same terms and conditions as are applicable to active
peer employees (including, without limitation, submission of proof by an Executive who seeks long term disability benefits that such Executive would have satisfied the conditions for such benefits had the Executive been an employee during the Salary
Continuation Period and terminated employment on or before the last day of such period). 

  
 5 

	 	4.8.	Executive Perquisites. Executive perquisites shall terminate effective as of the Participant’s Termination Date, and any Company-owned property shall be required to be returned to the Company no later than
such date. 

  

	 	4.9.	Outplacement and Financial Counseling Services. Each Participant shall be entitled to outplacement services at the expense of the Company for the twelve month period following the Termination Date, and
subject to such terms and conditions as the Plan Administrator, in its sole discretion, determines are appropriate. No cash shall be paid in lieu of such fees and costs. 

 

	 	4.10.	Restrictions on In-Kind Benefits. The in-kind benefits provided under each of Sections 4.5, 4.7 and 4.8 during any calendar year shall not affect the benefits to be provided under such section in any subsequent
calendar year. The right to such benefits shall not be subject to liquidation or exchange for any other benefit 

  

	 	4.11.	Other Coverage. Notwithstanding the foregoing, if such Participant is eligible to obtain a specific type of coverage under welfare plan(s) sponsored by another employer of such Participant (e.g. medical,
prescription, vision, dental, disability, individual life insurance benefits, group life insurance benefits, but excluding for the purposes of this sentence retiree benefits if such Participant is so eligible), then the Company shall not be
obligated to provide any such specific type of coverage. The Participant shall promptly notify the Plan Administrator of any such coverage. 

  

	5.	CHANGE IN CONTROL BENEFITS 

 A Participant described in Section 2.3 shall be
entitled to all Accrued Obligations and, subject to Section 6, benefits pursuant to this Section 5 if such a Participant has a Termination of Employment during a Post-Change Period or Imminent Control Change Period, and such Participant shall
not be eligible for benefits under Section 4 unless so expressly provided in this Section 5. 
  

	 	5.1.	Termination During a Post-Change Period. If, during a Post-Change Period, an eligible Executive has a Termination of Employment and becomes a Participant, the Company’s sole obligations under Section 4 and
Sections 5.1 and 5.2 shall be as set forth in this Section 5.1 (subject to Sections 5.3, 5.5, 5.6 and 6.0. 

  

	 	(a)	Severance Payments. The Company shall pay or provide (or cause to be provided) to such Participant, according to the payment terms set forth in Section 5.3 below, the following: 

 

	 	(i)	Annual Incentive for Year of Termination. An amount equal to the Annual Incentive applicable to such Participant under the Incentive Plan for the performance period in which the Termination Date occurs;

  
 6 

	 	(ii)	Deferred Compensation and Non-Qualified Defined Contribution Plans. All amounts previously deferred by, or accrued to the benefit of, such Participant under the Exelon Corporation Deferred Compensation Plan,
the Exelon Corporation Stock Deferral Plan or the Constellation Energy Group Inc. Deferred Compensation Plan, any successor plan, or under any other non-qualified defined contribution or deferred compensation plan of the Company, whether vested
or non-vested, together with any accrued earnings thereon, to the extent that such amounts and earnings have not been previously paid by the Company and are not provided under the terms of any such non-qualified plan; 

 

	 	(iii)	SERP Enhancement. An amount payable under the SERP equal to the positive difference, if any, between: 

  

	 	(1)	the lump sum value of such Participant’s benefit, if any, under the SERP, calculated as if such Participant had:

January 1, 2013 to the extent earned by and awarded to such Participant (i.e. as to which the applicable performance cycle has elapsed) as of the Termination Date, shall become fully vested at the actual level earned and awarded, and, to the extent
not yet earned by and awarded to such Participant (i.e. as to which the current performance cycle has not elapsed) as of the Termination Date, shall become fully vested at the earned level determined as of the last day of the applicable performance

 8 

	 	
covered the Participant or such Participant’s dependents as of the Termination Date, in accordance with the terms and conditions of such plans and applicable law. Such provision of welfare
benefits shall be subject to the following: 

  

	 	(i)	In determining benefits applicable under such Welfare Plans, such Participant’s annual compensation attributable to base salary and incentives for any plan year or calendar year, as applicable, shall be deemed to
be not less than such Participant’s Base Salary and annual incentive for the year in which the Termination Date occurs. 

  

	 	(ii)	The cost of such welfare benefits to such Participant and dependents under this Section 5.1(e) shall not exceed the cost of such benefits to peer executives who are actively employed during the Severance Period.

  

	 	(iii)	Health care coverage under this Section 5.1(e) shall be provided for the duration of the Severance Period in lieu of continuation coverage under Section 4980B of the Code and Section 601 to 609 of ERISA

	 	(iv)	If such Participant has, as of the last day of the Severance Period, attained age 50 and completed at least 10 years of service with the Company, such Participant shall be entitled to elect coverage under such Company
group health care programs for retirees as are in effect as of the Termination Date and are applicable to such Participant by the programs’ eligibility terms and conditions as though such Participant had attained such programs’ age and
service requirements ; provided, however, that for purposes hereof, any years of age and/or credited service granted to such Participant in any other plan or agreement between such Participant and the Company shall be taken into account. For
purposes of determining eligibility for (but not the time of commencement of) such retiree benefits, such Participant shall also be considered (1) to have remained employed until the last day of the Severance Period and to have retired on the
last day of such period, and (2) to have attained at least the age such Participant would have attained on the last day of the Severance Period. The eligibility for coverage and availability of programs or plans, the amounts charged for
coverage, and the other terms, conditions and limitations under the Company’s group health care programs or plans shall remain subject to the Company’s right to amend, change or terminate such programs or plans at any time.

  
 9 

 Notwithstanding the foregoing, if such Participant is eligible to obtain a specific type of
coverage under welfare plan(s) sponsored by another employer of such Participant (e.g. medical, prescription, vision, dental, disability, individual life insurance benefits, group life insurance benefits, but excluding for the purposes of this
sentence retiree benefits if such Participant is so eligible), then the Company shall not be obligated to provide any such specific type of coverage. The Participant shall promptly notify the Plan Administrator of any such coverage.

	 	(g)	Indemnification. Such Participant shall be indemnified and held harmless by the Company to the greatest extent permitted under applicable law and the Company’s by-laws if such Participant was, is, or is
threatened to be, made a party to any pending, completed or threatened action, suit, arbitration, alternate dispute resolution mechanism, investigation, administrative hearing or any other proceeding brought by a third party (and not by or on behalf
of the Company or its shareholders) whether civil, criminal, administrative or investigative, and whether formal or informal, by reason of the fact that such Participant is or was, or had agreed to become, a director, officer, employee, agent, or
fiduciary of the Company or any other entity which such Participant is or was serving at the request of the Company (“Proceeding”), against all expenses (including all reasonable attorneys’ fees) and all claims, damages,
liabilities and losses incurred or suffered by such Participant or to which such Participant may become subject for any reason; provided, that the Participant provides the Company written notice of any such Proceeding promptly after receipt and such
that the Company’s ability to defend shall not be prejudiced in any fashion and the Company shall have the right to direct the defense, approve any settlement and shall not be required to indemnify the Participant in connection with any
proceeding initiated by the Participant, including a counterclaim or crossclaim, unless such proceeding was authorized by the Company, and that the Participant fully cooperates in the investigation and defense of such Proceeding. 

 

	 	(h)	Directors’ and Officers’ Liability Insurance. For a period of six years after the Termination Date, the Company shall provide such Participant with coverage under a directors’ and officers’
liability insurance policy in an amount no less than, and on terms no less favorable than, those provided to peer executives of the Company from time to time. 

  

	 	5.2.	 Termination During an Imminent Control Change Period. If, during an Imminent Control Change Period, a Participant has a Termination of
Employment, then 

  
 10 

	 	
such Participant shall receive benefits at the time and in the manner provided in Section 4 and the Company’s sole obligations to such Participant under Sections 5.1 and 5.2 shall be as set
forth in this Section 5.2 (and subject to Sections 5.3, 5.5, 5.6 and 6). The Company’s obligations to such Participant under this Section 5.2 shall in all events be reduced by any amounts or benefits paid or provided pursuant to Section 4.

  

	 	(a)	Cash Severance Payments. If the Imminent Control Change Period culminates in a Change Date, the Company shall pay (or cause to be paid) to such Participant the amounts described in Section 5.1(a)(i) through
(v). Such amounts shall be paid to such Participant as described in Section 5.3, provided that amounts that would have been paid prior to the Change Date shall be paid in a lump sum (without interest) within 30 business days after the Change
Date. 

  

	 	(b)	Vested Stock Options. Such Participant’s Stock Options, to the extent vested on the Termination Date, 

  

	 	(i)	will not expire (unless such Stock Options would have expired had such Participant remained an employee of the Company) during the Imminent Control Change Period; and 

 

	 	(ii)	will continue to be exercisable after the Termination Date to the extent provided in the applicable grant agreement or the LTIP, and thereafter such Stock Options shall not be exercisable during the Imminent Control
Change Period. 

 If the Imminent Control Change Period lapses without a Change Date, then such Participant’s Stock
Options, to the extent vested on the Termination Date, may be exercised, in whole or in part, during the 30-day period following the lapse of the Imminent Control Change Period, or, if longer, the period during which such Participant’s vested
Stock Options could otherwise be exercised under the terms of the applicable grant agreement or the LTIP (but in no case shall any Stock Options remain exercisable after the date on which such Stock Options would have expired if such Participant had
remained an employee of the Company). 
 If the Imminent Control Change Period culminates in a Change Date, then effective upon the Change
Date, such Participant’s Stock Options, to the extent vested on the Termination Date, may be exercised in whole or in part by such Participant at any time until the earlier of the fifth anniversary of the Change Date or the option expiration
date for such Stock Options, provided that this Section 5.2(b) shall not limit the right of the Company to cancel the Stock Options in connection with a corporate transaction pursuant to the terms of the LTIP. 

  
 11 

	 	(c)	Non-vested Stock Options. Such Participant’s Stock Options that are not vested on the Termination Date: 

  

	 	(i)	will not expire (unless such Stock Options would have expired had such Participant remained an employee of the Company) during the Imminent Control Change Period; and 

 

	 	(ii)	will not continue to vest and will not be exercisable during the Imminent Control Change Period. 

If the Imminent Control Change lapses without a Change Date, such non-vested Stock Options will thereupon expire. 

If the Imminent Control Change culminates in a Change Date, then immediately prior to the Change Date, such non-vested Stock Options shall
become fully vested, and may thereupon be exercised in whole or in part by such Participant at any time until the earlier of the fifth anniversary of the Change Date, or the option expiration date for such Stock Options, provided that this Section
5.2(c) shall not limit the right of the Company to cancel the Stock Options in connection with a corporate transaction pursuant to the terms of the LTIP. 
  

	 	(d)	Performance Shares. Such Participant’s Performance Shares granted under the Exelon Long Term Performance Share Award Program under the LTIP will not be forfeited during the Imminent Control Change Period,
and will not continue to vest during the Imminent Control Change Period. If the Imminent Control Change lapses without a Change Date, such Performance Shares shall be governed according to the terms of Section 4. If the Imminent Control Change
Period culminates in a Change Date: 

  

	 	(i)	All Performance Shares granted to such Participant under the Exelon Long Term Performance Share Award Program under the LTIP prior to January 1, 2013, which, as of the Termination Date, have been earned by and awarded
to such Participant, shall become fully vested at the actual earned level on the Change Date, and 

  

	 	(ii)	All of the Performance Shares granted to such Participant under the Exelon Long Term Performance Share Award Program under the LTIP prior to January 1, 2013 which, as of the Termination Date, have not been earned
by and awarded to such Participant shall become fully vested on the Change Date at the actual earned level as of the last day of the applicable performance cycle, and 

 

	 	(iii)	With respect to all Performance Shares granted on or after January 1, 2013, such Performance Shares shall become vested and earned as set forth in the LTIP, as if the Executive had been involuntarily terminated without
cause. 

  

	 	(e)	Restricted Stock. Such Participant’s non-vested Restricted Stock will: 

  

	 	(i)	not be forfeited during the Imminent Control Change Period; and 

  

	 	(ii)	not continue to vest during the Imminent Control Change Period. 

  
 12 

 If the Imminent Control Change Period lapses without a Change Date, such non-vested Restricted
Stock shall thereupon be forfeited. 
 If the Imminent Control Change Period culminates in a Change Date, then immediately prior to the
Change Date, such Participant’s Restricted Stock shall (except as expressly provided to the contrary in the award) become fully vested, and within ten business days after the Change Date, the Company shall deliver to such Participant all of
such shares theretofore held by or on behalf of the Company, which will be subject to the same terms which other stockholders of the Company receive in the transaction. 
  

	 	(f)	Cash Performance Awards. All Cash Performance Awards shall become fully vested in accordance with the terms of the underlying award documents. 

 

	 	(g)	Continuation of Welfare Benefits. The Participant and the Participant’s dependents shall be eligible for welfare benefits (other than any severance pay that may be considered a welfare benefit) in accordance
with the terms and conditions of the applicable plans during the Imminent Control Change Period, to the same extent as if such Participant had remained employed during such period, subject to the following: 

 

	 	(i)	in determining benefits applicable under such Welfare Plans, such Participant’s annual compensation attributable to base salary and incentives for any plan year or calendar year, as applicable, shall be deemed to
be not less than such Participant’s Base Salary and annual incentive for the year in which the Termination Date occurs; 

  

	 	(ii)	the cost of such welfare benefits to such Participant and dependents under this Section 5.2(g) shall not exceed the cost of such benefits to peer executives who are actively employed by the Company during the Imminent
Control Change Period; and 

  

	 	(iii)	Health care coverage under this Section 5.2(g) shall be provided for the duration of the Severance Period in lieu of continuation coverage under Section 4980B of the Code and Section 601 to 609 of ERISA
(“COBRA”) for the same period. At the end of the Severance Period, COBRA continuation coverage may be elected for the remaining balance of the statutory coverage period, if any. 

If the Imminent Control Change Period lapses without a Change Date, welfare benefit plan coverage under this Section 5.2(g) shall thereupon
cease, subject to such Participant’s rights, if any, to continued coverage under a Welfare Plan, Section 4, or applicable law. If the Imminent Control Change Period culminates in a Change Date, then for the remainder of the Severance Period,
the Participant and his or her dependents shall continue to be eligible for welfare benefits as described in, and subject to the limitations of Section 5.1(e). 

  
 13 

 Notwithstanding the foregoing, if such Participant obtains a specific type of coverage under
welfare plan(s) sponsored by another employer of such Participant (e.g. medical, prescription, vision, dental, disability, individual life insurance benefits, group life insurance benefits, but excluding for the purposes of this sentence retiree
benefits if such Participant is so eligible), then the Company shall not be obligated to provide any such specific type of coverage. The Participant shall immediately notify the Plan Administrator of any such coverage. 

 

	 	(h)	Indemnification. Such Participant shall be indemnified and held harmless by the Company to the same extent as provided in Section 5.1(g), but only during the Imminent Control Change Period (or greater period
provided under the Company’s by-laws) if the Imminent Control Change Period lapses without a Change Date. 

  

	 	(i)	Termination During an Imminent Control Change Period: Directors’ and Officers’ Liability Insurance. The Company shall provide the same level of directors’ and officers’ liability insurance for
such Participant as provided in Section 5.1(h), but only during the Imminent Control Change Period (or greater period provided under the Company’s by-laws) if the Imminent Control Change Period lapses without a Change Date. 

 

	 	5.3.	Timing of Severance Payments. Unless otherwise specified herein, the Accrued Obligations and the amount described in Section 5.1(a)(i) shall be paid within 30 business days of the Termination Date, and such
amounts shall be considered “short-term deferrals” within the meaning of Section 409A of the Code. The amounts described in Sections 5.1(a)(ii), (iii) and (iv) shall be paid in accordance with the applicable deferred compensation plan or
the SERP and the Participant’s distribution election thereunder as of the Termination Date (or, if no affirmative election is in effect as of such date, the default election in effect with respect to the Participant as of such
date). Subject to Section 13.13, the severance payments described in Section 5.1(a)(v) shall be paid during the Severance Period, beginning no later than the second paydate which occurs after the Termination Date, in periodic payments to a
Participant according to the Company’s normal payroll practices at a monthly rate equal to 1/12 of the sum of (i) such Participant’s Base Salary plus (ii) the Severance Incentive (if any). The in-kind benefits and reimbursements provided
under each of Sections 5.1(e), 5.1(h), 5.2(g) and 5.2(i) during any calendar year shall not affect the benefits or reimbursements to be provided under such section in any subsequent calendar year. The right to such benefits and reimbursements
shall not be subject to liquidation or exchange for any other benefit. 

  
 14 

	 	5.4.	Other Terminations of Employment by the Company or a Participant. 

  

	 	(a)	Obligations. If, during a Post-Change Period or an Imminent Control Change Period, (i) the Company terminates an eligible Executive’s employment for Cause (or causes a Participant to be terminated for
Cause) (“Cause Termination”) or disability (as determined by the Plan Administrator in good faith), (ii) an Executive elects to retire or otherwise terminate employment other than for Good Reason, disability or death, or (iii) an
eligible Executive’s employment terminates on account of death, the Company shall have no obligations to such Executive under Section 5. The remaining applicable provisions of this Plan (including the Restrictive Covenants) shall continue to
apply. 

  

	 	(b)	Procedural Requirements. The Company shall strictly observe or cause to be strictly observed each of the following procedures in connection with any Cause Termination during a Post-Change Period or an
Imminent Control Change Period: an eligible Executive’s termination of employment shall not be deemed to be for Cause under this Section 5.4 unless and until there shall have been delivered to such Executive a written notice of the
determination of the Chief Executive Officer of the Executive’s employer (“CEO”) (after reasonable written notice of such consideration by the CEO of acts or omissions alleged to constitute Cause is provided to such Executive
and such Executive is given an opportunity to present a written response to the CEO regarding such allegations), finding that, in his or her good faith opinion, such Executive’s acts, or failure to act, constitutes Cause and specifying the
particulars thereof in detail. 

  

	 	5.5.	Sole and Exclusive Obligations. The obligations of the Company under this Plan with respect to any Termination of Employment occurring during a Post-Change Period or Imminent Control Change Period shall
supersede any severance obligations of the Company in any other plan of the Company or agreement between such Participant and the Company, including, without limitation, Section 4, any offer of employment or employment contract of the Company which
provides for severance benefits, except as explicitly provided in Section 5.2 or to the extent such Participant is ineligible for such benefits or such benefits are waived pursuant to Section 2.1. 

 

	 	5.6.	Payment Capped. If at any time or from time to time, it shall be determined by the Company’s independent auditors that any payment or other benefit to a Participant pursuant to Section 4 or 5 of this Plan or
otherwise (“Potential Parachute Payment”) is or will become subject to the excise tax imposed by Section 4999 of the Code or any similar tax payable under any United States federal, state, local, foreign or other law
(“Excise Taxes”), then the Potential Parachute Payments payable to such Participant shall be reduced to the largest amount which would both (a) not cause any Excise Tax to be payable by such Participant and (b) not cause any
Potential Parachute Payments to become nondeductible by the Company by reason of Section 280G of the Code (or any successor provision).

terms and conditions provided in the Plan. 
  

	9.	ADMINISTRATION OF THE PLAN 

 The Plan shall be administered on a day-to-day basis
by the Vice President, Corporate Compensation of Exelon (the “Plan Administrator”). The Plan Administrator has the sole and absolute power and authority to interpret and apply the provisions of this Plan to a particular
circumstance, make all factual and legal determinations, construe uncertain or disputed terms and make eligibility and benefit determinations in such manner and to such extent as the Plan Administrator, in his or her sole discretion may determine.
Benefits under the Plan will be paid only if the Plan Administrator, in his or her discretion, determines that an individual is entitled to them; provided, however, that any dispute after the claims procedure under Section 10 has been exhausted
regarding whether an Executive’s termination of employment for purposes of Section 5 is based on either Good Reason or Cause may, at the election of the Executive, be submitted to binding arbitration pursuant to Section 11. 

The Plan Administrator may promulgate any rules and regulations it deems necessary to carry out the purposes of the Plan or to interpret the
terms and conditions of the Plan; provided, however, that no rule, regulation or interpretation shall be contrary to the provisions of the Plan. The rules, regulations and interpretations made by the Plan Administrator shall, where appropriate,
be applied on a consistent basis with respect to similarly situated Executives, and shall be final and binding on any Executive or former Executive and any successor in interest. 

The Plan Administrator may delegate any administrative duties, including, without limitation, duties with respect to the processing, review,
investigation, approval and payment of severance pay and provision of severance benefits, to designated individuals or committees. The Plan Administrator may amend any Participant’s Severance Agreement to the extent the Plan Administrator
determines it is reasonably necessary or appropriate to do so to comply with section 409A of the Code. 

  
 26 

	10.	CLAIMS PROCEDURE 

 The Plan Administrator shall determine the status of an
individual as an Executive and the eligibility and rights of any Executive or former Executive as a Participant to any severance pay or benefits hereunder. Any Executive or former Executive who believes that he or she is entitled to receive
severance pay or benefits under the Plan, including severance pay or benefits other than those initially determined by the Plan Administrator, may file a claim in writing with the Plan Administrator. Within 90 days after the receipt of the
claim the Plan Administrator shall either allow or deny the claim in writing, unless special circumstances require an extension of time for processing, in which case a decision shall be rendered as soon as practicable, but not later than 180 days
after receipt of a request for review. 
 A claimant whose claim is denied (or his or her duly authorized representative) may, within 60
days after receipt of the denial of his or her claim, request a review upon written application to Exelon’s Chief Human Resources Officer or other officer designated by Exelon and specified in the claim denial; review (without charge) relevant
documents; and submit written comments, documents, records and other information relating to the claim. 
 The Chief Human Resources Officer
or other designated officer shall notify the claimant of his or her decision on review within 60 days after receipt of a request for review unless special circumstances require an extension of time for processing, in which case a decision shall
be rendered as soon as possible, but not later than 120 days after receipt of a request for review. Notice of the decision on review shall be in writing. The officer’s decision on review shall be final and binding on any claimant or any
successor in interest. 
 In reviewing a claim or an appeal of a claim denial, the Plan Administrator and the Chief Human Resources Officer
or other designated by Exelon shall have all of the powers and authority granted to the Plan Administrator pursuant to Section 9. 
  

	11.	ARBITRATION  

 Any dispute, controversy or claim between the parties hereto
concerning whether an Executive’s termination of employment for purposes of Section 5 is based on either Good Reason or Cause may, after the claims procedure under Section 10 has been exhausted and at the election of the Executive, be settled
by binding arbitration in Chicago, Illinois, before an impartial arbitrator pursuant to the rules and regulations of the American Arbitration Association (“AAA”) pertaining to the arbitration of employee benefit plan
disputes. The costs and fees of the arbitrator shall be borne equally by the parties, regardless of the result of the arbitration. No arbitration shall be commenced after the date when institution of legal or equitable proceedings
based upon such subject matter would be barred by the applicable statutes of limitations. Notwithstanding anything to the contrary contained in this Section or elsewhere in this Plan, any party may seek relief in the form of specific
performance, injunctive or other equitable relief in order to enforce the decision of the arbitrator, and the Company may seek injunctive relief to enforce the above-referenced statutes of limitations. 

 

	12.	AMENDMENT OR TERMINATION OF PLAN 

 Exelon’s Chief Human Resources Officer or
another designated officer of the Company may amend, modify or terminate the Plan at any time by written instrument; provided, however, 

  
 27 

 
that no amendment, modification or termination shall deprive any Participant of any payment or benefit that the Plan Administrator previously has determined is payable under the Plan.
Notwithstanding the foregoing, no amendment or termination that reduces the severance payments or materially adversely affects any Participant’s other benefits under Section 5 shall become effective as to such Participant during: (a) the
24-month period following a Change Date or (b) during an Imminent Control Change Period (unless such Participant consents to such termination or amendment). Any purported Plan termination or amendment in violation of this Section 12 shall be void
and of no effect. 
  

	13.	MISCELLANEOUS 

  

	 	13.1.	Limitation on Rights. Participation in the Plan is limited to the individuals described in Sections 2 and 3, and the benefits under the Plan shall not be payable with respect to any voluntary or
involuntary termination of employment that is not a Termination of Employment. 

  

	 	13.2.	Cooperation By Participants. During the Salary Continuation Period or Severance Period, as applicable, the Executive shall (a) be reasonably available to the Company to respond to requests by them for
information pertaining to or relating to matters which may be within the knowledge of the Executive and (b) cooperate with the Company in connection with any existing or future litigation or other proceedings brought by or against the Company,
its subsidiaries or affiliates, to the extent the Company deems the Executive’s cooperation reasonably necessary. 

  

	 	13.3.	No Set-off by Company. This Section shall apply solely with respect to a Termination of Employment during a Post-Change Period or an Imminent Control Change Period that culminates in a Change Date. Except as
provided in Section 6, a Participant’s right to receive when due the payments and other benefits provided for under Section 5 of this Plan is absolute, unconditional and subject to no setoff, counterclaim or legal or equitable defense.

  

	 	13.4.	No Mitigation. A Participant shall not have any duty to mitigate the amounts payable by the Company under this Plan by seeking new employment following termination. Except as specifically otherwise provided in
this Plan, all amounts payable pursuant to this Plan shall be paid without reduction regardless of any amounts of salary, compensation or other amounts which may be paid or payable to the Executive as the result of the Executive’s employment by
another, unaffiliated employer. 

  

	 	13.5.	Headings. Headings of sections in this document are for convenience only, and do not constitute any part of the Plan. 

  

	 	13.6.	 Severability. If any one or more Sections, subsections or other portions of this Plan are declared by any court or governmental authority
to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any Section, subsection or other portion not so declared to be unlawful or invalid. Any Section, subsection or other portion so declared to be unlawful or
invalid shall be construed so as to effectuate the terms of such Section, subsection or other portion 

  
 28 

	 	
to the fullest extent possible while remaining lawful and valid. Notwithstanding the foregoing, in the event a determination is made that the Restrictive Covenants are invalid or
unenforceable in whole or in part, then the Severance Agreement with respect to the Participant subject to such determination shall be void and the Company shall have no obligation to provide benefits under this Plan to such Participant.

  

	 	13.7.	Governing Law. The Plan shall be construed and enforced in accordance with the applicable provisions of ERISA and Section 409A of the Code. 

 

	 	13.8.	No Right to Continued Employment. Nothing in this Plan shall guarantee the right of a Participant to continue in employment, and the Company retains the right to terminate a Participant’s employment at any
time for any reason or for no reason. 

  

	 	13.9.	Successors and Assigns. This Plan shall be binding upon and inure to the benefit of Exelon and its successors and assigns and shall be binding upon and inure to the benefit of a Participant and his or her legal
representatives, heirs and legatees. Exelon shall cause any successor to assume the Plan. No rights, obligations or liabilities of a Participant hereunder shall be assignable without the prior written consent of Exelon Corporation. In the event of
the death of a Participant prior to receipt of severance pay or benefits to which he or she is entitled hereunder (and, with respect to benefits under Section 4 or Section 5, after he or she has signed the Waiver and Release), the severance pay
described in Sections 4.1, 5.1, or 5.2, as applicable, shall be paid to his or her estate, and the Participant’s dependents who are covered under any health care plans maintained by the Company shall be entitled to continued rights under
Section 4.5 or Section 5.1(e) or Section 5.2(g), as applicable; provided that the estate or other successor of the Participant has not revoked such Waiver and Release. 

 

	 	13.10.	Notices. All notices and other communications under this Plan shall be in writing and delivered by hand, by nationally-recognized delivery service that promises overnight delivery, or by first-class
registered or certified mail, return receipt requested, postage prepaid, addressed as follows: 

 If to a Participant, to such
Participant at his most recent home address on file with the Company. 
 If to the Company: to the Plan Administrator. 

or to such other address as either party shall have furnished to the other in writing. Notice and communications shall be effective when
actually received by the addressee. 
  

	 	13.11.	Number and Gender. Wherever appropriate, the singular shall include the plural, the plural shall include the singular, and the masculine shall include the feminine. 

 

	 	13.12.	 Tax Withholding. The Company may withhold from any amounts payable under this Plan or otherwise payable to a Participant or beneficiary any
Taxes the 

  
 29 

	 	
Company determines to be appropriate under applicable law and may report all such amounts payable to such authority in accordance with any applicable law or regulation. 

 

	 	13.13.	Section 409A. This Plan shall be interpreted and construed in a manner that avoids the imposition of additional taxes and penalties under Section 409A of the Code (“409A Penalties”). In the event the
terms of this Plan would subject a Participant to 409A Penalties, the Company may amend the terms of the Plan to avoid such 409A Penalties, to the extent possible. The payments to a Participant pursuant to this Plan are intended to be exempt from
Section 409A of the Code to the maximum extent possible, under either the separation pay exemption pursuant to Treasury regulation §1.409A-1(b)(9)(iii) or as a short-term deferral pursuant to Treasury regulation §1.409A-1(b)(4), and for
purposes of the separation pay exemption, each installment paid to a Participant shall be considered a separate payment. Notwithstanding any other provision in this Plan, if on the date of a Participant’s Termination Date the Participant is a
Specified Employee, then to the extent any amount payable under this Plan constitutes the payment of nonqualified deferred compensation, within the meaning of Section 409A of the Code, that under the terms of this Plan would be payable prior to the
six-month anniversary of the Termination Date, such payment shall be delayed until the earlier to occur of (A) the six-month anniversary of the Termination Date or (B) the date of the Participant’s death. Any reimbursement (including any
advancement) payable to a Participant pursuant to this Plan shall be conditioned on the submission by the Participant of all expense reports reasonably required by the Company under any applicable expense reimbursement policy, and shall be paid to
the Participant within 30 days following receipt of such expense reports (or invoices), but in no event later than the last day of the calendar year following the calendar year in which the Participant incurred the reimbursable expense. Any amount
of expenses eligible for reimbursement during a calendar year shall not affect the expenses eligibility for reimbursement during any other calendar year. The right to reimbursement pursuant to this Plan shall not be subject to liquidation or
exchange for any other benefit.
