PECO Energy Company Supplemental Pension Benefit Plan

 Exhibit 10.20 
 PECO Energy Company 
 Supplemental Pension Benefit Plan 
 (Effective Date: November 1, 1981) 
 (As
Amended and Restated Effective January 1, 2009) 
 PECO Energy Company (“PECO” or the “Company”) originally
established the PECO Energy Company Deferred Compensation and Supplemental Pension Benefit Plan (the “Plan”). The outstanding shares of PECO were subsequently exchanged with shares of Exelon Corporation (“Exelon”) causing Exelon
to become PECO’s parent (the “Share Exchange”). Immediately thereafter, Unicom Corporation merged with and into Exelon (the “Merger”). In connection with the Share Exchange and Merger, Exelon assumed sponsorship of the Plan.
Effective January 1, 2001, the portion of the Plan that provided for elective deferrals of compensation and individual deferral accounts was merged into what is now known as the Exelon Corporation Deferred Compensation Plan. In order to reflect
such merger and to comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), the Plan is hereby amended and restated as set forth herein, effective January 1, 2009, and shall thereafter be known as
the PECO Energy Company Supplemental Pension Benefit Plan. 
 The purposes of this Plan are to permit the total pension payable to eligible
key management and executive employees of PECO and its Subsidiaries (as defined in Paragraph 2), and select employees of PECO and its subsidiaries who exceed the to be determined on a basis that is no less favorable than other employees of PECO.

 1. Administration. This Plan shall be administered by Exelon’s Director of Employee Benefit Plans and Programs, or such other
person designated by Exelon’s Chief Human Resources Officer from time to time. The Plan Administrator shall have discretionary authority to interpret the Plan; make factual determinations; establish such rules and regulations 

 
of plan administration that it deems appropriate. The Plan Administrator’s decisions with respect to the construction, administration and interpretation
of the Plan shall be conclusive and binding. The cost of the plan administration shall be paid by the Company, and shall not be charged against the benefits of Plan participants. 
 2. Eligibility. Eligibility under the Plan is restricted to executive, key management and other select employees of PECO and its Subsidiaries who
participate in the PECO Energy Service Annuity Plan under the Exelon Corporation Retirement Program (the “Service Annuity Plan”) and who exceed the maximum benefit or maximum compensation limits of the Code. “Subsidiary” shall
mean a corporation in which PECO owns, directly or indirectly, at least 50% of the combined voting power of all classes of stock entitled to vote, and which is approved by the Plan Administrator to participate in the Plan. Individuals who have
accrued benefits under the Service Annuity Plan, and who elect to transfer from such plan to the Exelon Corporation Cash Balance Pension Plan, shall cease to participate in this Plan and shall have their supplemental pension benefits paid from the
Exelon Corporation Supplemental Management Retirement Plan, and this Plan shall have no further obligation to provide supplemental benefits following such a transfer. 
 3. Supplemental Pension Benefit. The Plan will supplement a participant’s pension or preretirement death benefit payable under the PECO Service Annuity Plan (the “Service Annuity Plan”) by the
amount which is the difference, if any, between such unreduced pension or pre-retirement death benefit and the unreduced monthly pension or preretirement death benefit which would have been payable under the Service Annuity Plan as if: (i) the
provisions of that Plan were administered without regard to the maximum benefit limitations or the maximum compensation limitations imposed under the Code; (ii) for purposes of calculating 

  

 2 

 
the participant’s benefit under Section 3.1(a) of the Service Annuity Plan (the “2% accrued” formula), the participant’s salary with
respect to earnings accrued prior to January 1, 2001, includes in the year payable (whether or not deferred) the amount of any award under PECO’s Management Incentive Compensation Plan or the prior Incentive Compensation Plan;
(iii) for purposes of calculating the participant’s benefit under Section 3.1(b) of the Service Annuity Plan (the “minimum” formula), the participant’s annual base salary with respect to earnings accrued prior to
January 1, 2001, includes the amount of any award under PECO’s Management Incentive Compensation Plan, whether paid currently or deferred, and in either case imputed ratably over the months worked by the participant in the year earned; and
(iv) for purposes of both benefit formulas under the Service Annuity Plan, the participant’s salary had not been reduced (whether before or after the Effective Date) in connection with a deferral of cash compensation. In addition, with
respect to earnings accrued prior to January 1, 2001, for any participant whose compensation was established by the Board, such supplemental benefit will also reflect the following adjustment: for purposes of calculating the participant’s
benefit under Section 3.l(b) of the Service Annuity Plan (the “minimum” formula), the participant’s annual base salary shall include the amount of any award under PECO’s prior Incentive Compensation Plan, whether paid
currently or deferred, and in either case imputed ratably over the months worked by the participant in the year earned. This supplemental benefit shall be adjusted in accordance with the provisions of the Service Annuity Plan with respect to age and
service to reflect the benefit commencement date and, to the extent the Plan Administrator determines is appropriate, any post-retirement benefit increases with respect to benefits under the Service Annuity Plan.

 4. Time and Manner of Payment. 
 (a) Time and Manner of Payment of Benefits Commencing Prior to January 1, 2009. The distribution of any Plan benefit that
commenced prior to January 1, 2009 shall continue to be paid in accordance with the terms of the Plan as in effect as of the date such distribution commenced; provided, however, that in the case of benefits commencing on or after
January 1, 2005, any such distribution shall be subject to administrative procedures established by the Company or the Plan Administrator for the purpose of to complying with Section 409A of the Code. 
 (b) Time and Manner of Payment of Grandfathered Benefits. All Plan benefits to which a Participant is entitled that had accrued and
were vested as of December 31, 2004 (“Grandfathered Benefits”) shall be paid in accordance with this Paragraph 4(b), and such benefits are intended to be exempt from Section 409A of the Code, and the Plan shall be construed and
administered in accordance with such intent. The portion of a Plan benefit that is the Grandfathered Benefit shall be determined in accordance with Treasury Regulation §1.409A-6(a)(3). 
 (i) Except as otherwise determined by the Plan Administrator, or as otherwise elected by the participant under this Paragraph,
supplemental pension and death benefits will be in the same form and paid to the employee (or on his or her behalf, to his or her beneficiaries) in the same manner as payment of retirement and death benefits under the Service Annuity Plan.

 (ii) (1) In any calendar year before the participant’s termination of employment, and in accordance with procedures
established by the Plan Administrator, a participant may elect to receive the present value of the supplemental retirement benefit payable to the participant under Paragraph 3 in a lump sum upon the participant’s termination of employment.

  

 4 

 (2) The present value of amounts payable in a lump sum pursuant to this Paragraph
4(b)(ii) will be actuarially determined by discounting the expected stream of annuity payments (based upon the life expectancy of the participant and, if applicable, the life expectancy of the participant’s beneficiary as provided under the
Contingent Annuity Option of the Service Annuity Plan, determined as of the date of payment under the mortality table used in the most recent actuarial analysis of the Service Annuity Plan) at a rate equivalent to the Pension Benefit Guaranty
Corporation (PBGC) Immediate Annuity Rate in effect on January 1 of the year of retirement. Such calculation shall reflect the Contingent Annuity Option benefit under the Service Annuity Plan if the participant otherwise satisfies the
conditions for that benefit, but shall not reflect any possible post-retirement benefit increases; provided, however, that, if the participant’s Contingent Annuity Option election under the Service Annuity Plan is not irrevocable at the time
the lump sum payment is made hereunder, the participant will receive an initial lump sum payment reflecting the Contingent Annuity Option resulting in the smallest lump sum payment from the Plan and, at age 65 (or at the participant’s death, if
earlier), a payment will be made to the participant (or his or her beneficiary) equal to the balance due the participant (which shall be the present value of the difference between the value of the total pension payable to the participant or
beneficiary at such time over the sum of the value of benefits payable to the participant or beneficiary under the Service Annuity Plan and the lump sum previously paid, taking into account the Contingent Annuity Option then in effect, the
Contingent Annuity Option in effect 

  

 5 

 
between retirement and age 65, and increases in benefit payable under the Service Annuity Plan due to adjustment of Code limitations (which, for purposes of
determining the amount of the Grandfathered Benefits, shall not take into account increases in such limitations after October 3, 2004), and reflecting the interest rate used to calculate the prior lump sum). The specific calculation methodology
and manner of payment, which will be made in a manner acceptable to the Plan Administrator, will be applied in a uniform, non-discriminatory fashion. An election made pursuant to Paragraph 4(b)(ii)(1), once made, shall be irrevocable; provided,
however, that a participant who made an election prior to June 1, 1993 to receive the entire supplemental retirement benefit payable to the participant hereunder in a lump sum may, while employed by PECO, make one subsequent election on or
after June 1, 1993 to receive less than the full benefit in a lump sum, subject to the timing limitations described in Paragraph 4(b)(ii)(l). 
 (iii) (1) A participant may elect to have supplemental death benefits under Paragraph 3 paid to such beneficiary or beneficiaries as the participant may designate in writing, in the manner specified by the Plan
Administrator. A change in beneficiary designation may be made at any time until the participant’s death, notwithstanding that the form and amount of the benefit may be fixed upon the participant’s termination of employment or other inter
vivos determining event. In the absence of a written beneficiary designation, death benefits will be paid to the beneficiary or beneficiaries entitled to the participant’s survivor and death benefits under the Service Annuity Plan. 

(2) Should a participant who has made a lump sum election as described in Paragraph 4(b)(ii)(1) prior to June 1, 1993 die between
the time such 

  

 6 

 
election is made and the date payments are scheduled to begin, the present value of supplemental death benefits payable to the participant’s beneficiary
under Paragraph 3 shall be paid in a lump sum to the participant’s beneficiary as soon as administratively practicable following the participant’s death; provided, however, that the participant has not made a contrary election pursuant to
the following sentence. In accordance with procedures prescribed by the Plan Administrator, during his or her employment a participant (including a participant described in the preceding sentence), may elect, or revoke or change a prior election, to
have the present value of all or a portion of the supplemental death benefits payable to the participant’s beneficiary under Paragraph 3 paid to the beneficiary in a lump sum as soon as administratively practicable following the
participant’s death; provided, however, that such election, or revocation or change, will not be effective unless made in any calendar year prior to the year in which the participant dies and at least ninety (90) days prior to the date of
such participant’s death. 
 (3) The present value of amounts payable in a lump sum pursuant to Paragraph 4(b)(iii) will
be actuarially determined by discounting the expected stream of annuity payments (based upon the beneficiary’s life expectancy determined as of the date of payment under the mortality table used in the most recent actuarial analysis of the PECO
Service Annuity Plan) at a rate equivalent to the Pension Benefit Guaranty Corporation (PBGC) Immediate Annuity Rate in effect on January 1 of the year of the participant’s death; provided, however, that a lump sum payable to the
beneficiary of a participant who made a lump sum election under this Paragraph 4 prior to June 1, 1993 (even if such election was later modified, or revoked and reinstated, with respect to the participant’s beneficiary) shall be valued
using the PBGC Immediate Annuity Rate in effect during the month such election was made, if the use of such rate would result in a larger lump sum payment. 
  

 7 

 (c) Time and Manner of Payment of Non-Grandfathered Benefits. All Plan benefits
other than those payable pursuant to Paragraphs 4(a) and 4(b) shall be paid in accordance with this Paragraph 4(c), and such benefits (the “Non-Grandfathered Benefits”) are intended to comply with Section 409A of the Code, and the
Plan shall be construed and administered in accordance with such intent. 
 (i) Elections of Time and Form of Payment.
Subject to the delay in the receipt of payments pursuant to clause (iii) below, a participant’s Non-Grandfathered Benefit shall commence within ninety days after (A) the date of the participant’s separation from service, within
the meaning of Section 409A of the Code, or (B) the later to occur of (I) the date of the participant’s separation from service and (II) the date on which the participant attains an age, not earlier than age 50 and not later than
age 65, as elected by the participant in accordance with procedures prescribed by the Plan Administrator (such commencement date, the “Non-Grandfathered Commencement Date”). Each participant shall elect his or her Non-Grandfathered
Commencement Date not later than 30 days after the first day of the calendar year immediately following the first year in which the participant accrues a Non-Grandfathered Benefit under the Plan; provided that (x) each person who is a
participant in the Plan prior to December 31, 2008 shall be permitted to elect his or her Non-Grandfathered Commencement Date prior to December 31, 2008 in accordance with procedures prescribed by the Company and the transition rule set
forth in IRS Notice 2005-1, Q&A-19(c), and extended 

  

 8 

 
in the preamble to regulations proposed under Section 409A of the Code, IRS Notice 2006-79 and IRS Notice 2007-86, which permits participants in
deferred compensation plans to change the date on which deferred compensation is payable, and (y) to the extent a Non-Grandfathered Benefit provided under Paragraph 3 hereof is not an “excess benefit plan,” within the meaning of
Treasury Regulation §1.409A-2(a)(7)(iii), the participant shall elect his or her Non-Grandfathered Commencement Date not later than 30 days after the date on which such participant first becomes eligible to participate in the Plan or any other
plan that is aggregated with the Plan under Section 409A of the Code. Non-Grandfathered Benefits shall be paid in the form of a lump sum payment or as an annuity, as elected by the participant at the time the participant elects his or her
Non-Grandfathered Commencement Date. A participant who elects to receive his or her Non-Grandfathered Benefit in the form of an annuity may elect the form of such annuity prior to the Non-Grandfathered Commencement Date in accordance with procedures
prescribed by the Plan Administrator, provided that the form of annuity elected by the participant (1) is an annuity option that is available under the Qualified Plan at the time such election is made and (2) is the actuarial equivalent,
within the meaning of Section 409A of the Code, of the single life annuity option available under the Qualified Plan. 
 (ii) Actuarial Adjustment of Non-Grandfathered Benefits. If a participant elects to receive his or her Non-Grandfathered Benefit in the form of a lump sum or an annuity other than a single life annuity for the life of the participant
or if the participant’s Plan benefit is paid or commences earlier or later 

  

 9 

 
than the participant’s normal retirement date under the Service Annuity Plan, the participant’s Non-Grandfathered Benefit shall be actuarially
adjusted to reflect such other form of pension benefit or pension starting date, or both, as the case may be, using the same actuarial factors that would be used to make comparable adjustments to the participant’s pension benefit under the
Service Annuity Plan. 
 (iii) Six-Month Delay for Specified Employees. Pursuant to Section 409A of the Code, if
payment of a participant’s Non-Grandfathered Benefit would commence as of the participant’s separation from service pursuant to clause (i) above and such participant is a “specified employee,” within the meaning of
Section 409A of the Code, then no payments with respect to such benefit shall be made prior to the month following the six-month anniversary of such separation from service, and during such month (A) if the participant has elected annuity
payments, the participant shall receive an initial payment equal to seven times the amount of the monthly payment determined in accordance with clause (i) or (ii) above, and thereafter the participant shall receive the regular monthly
payments determined pursuant to clauses (i) and (ii) above and (B) if the participant elected a lump sum distribution shall receive such distribution plus interest for such six-month period using the discount rate for December of the
year preceding the year that includes the distribution date. If a participant dies following the participant’s separation from service but prior to the commencement of payments pursuant to this clause (iii), the amount that would have been paid
to the participant prior to the date of death, without regard to the six-month delay in payment pursuant to this clause (iii), shall be paid to the participant’s beneficiary within ninety (90) days after the last day of the calendar
quarter that includes the date of the participant’s death. 
  

 10 

 (iv) Survivors’ Benefits. Any survivors’ benefit described in Paragraph
3 that is payable with respect to a Non-Grandfathered Benefit shall be payable in accordance with the form of payment election in effect for the participant and shall commence within 90 days after the date of the participant’s death.

 5. Claims Procedure. In accordance with the regulations of the U.S. Department of Labor, the Plan Administrator shall
(i) provide adequate notice in writing to any Participant or beneficiary whose claim for benefits is denied, setting forth the specific reasons for such denial and written in a manner calculated to be understood by such Participant or
beneficiary and (ii) afford a reasonable opportunity to any Participant or beneficiary whose claim for benefits has been denied for a full and fair review by a designated officer of the Company of the decision denying the claim. 
 6. Amendment / Discontinuance. The Compensation Committee of Exelon or its designee shall have the exclusive authority to alter, amend, suspend, or
terminate the Plan at any time; provided that, except as permitted by Section 409A of the Code, no such alteration, amendment, suspension, or termination shall result in the payment of benefits in any manner than is otherwise provided in this
Plan. 
 7. No Right to Continued Employment. The Plan shall not confer upon any person any right to be continued in the employment of
PECO 
  

 11 

 8. Non-Assignment of Benefits. Notwithstanding anything contained in the Plan to the contrary, it
shall be a condition of the payment of benefits under this Plan that neither such benefits nor any portion thereof shall be assigned, alienated or transferred to any person voluntarily or by operation of any law, including any assignment, division
or awarding of property under state domestic relations law (including community property law). If any person shall endeavor or purport to make any such assignment, alienation or transfer, amounts otherwise provided hereunder shall cease to be
payable to any person 
 9. Governing Law. To the extent benefits provided under the Plan restore benefits reduced by application of
the limitations contained in section 415 of the Code, the Plan is intended to be an excess benefit plan within the meaning of Section 3(36) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”). The Plan is
otherwise intended to constitute an unfunded plan maintained primarily for the purpose of providing deferred compensation to a select group of management or highly compensated employees within the meaning of sections 201(2), 301(a)(3) and 401(a)(1)
of ERISA and Department of Labor Regulation § 2520.104-23. The Plan shall be governed by the law of the Commonwealth of Pennsylvania, to the extent such law is not preempted by ERISA or other applicable federal law.

 EXELON CORPORATION 
 CHANGE-IN-CONTROL EMPLOYMENT AGREEMENT 
 THIS AGREEMENT, dated as of January 1, 2009 (the “Agreement Date”), is made by and among Exelon Corporation, incorporated under the
laws of the Commonwealth of Pennsylvania (together with successors thereto, the “Company”), on behalf of itself and
                                        ,
a                                         
company (together with successors thereto, the “Subsidiary”), and                      (“Executive”).

 RECITALS 
 The Board of
Directors of the Company (the “Board”) has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued services of the Executive, despite the possibility or
occurrence of a Change in Control of the Company. The Board believes it is imperative to reduce the distraction of the Executive that would result from the personal uncertainties caused by a pending or threatened Change in Control or a Significant
Acquisition, to encourage the Executive’s full attention and dedication to the Company, and to provide the Executive with compensation and benefits arrangements upon a Change in Control which are competitive with those of similarly-situated
corporations. This Agreement is intended to accomplish these objectives. 
 Article I.

Agreement, the terms specified below shall have the following meanings:

any Annual Incentive earned but not yet paid with respect to the Company’s latest fiscal year ended prior to the Termination Date.

 1.3 “Accrued Obligations” means, as of any date, the sum of Executive’s Accrued Base Salary, Accrued Annual Incentive, any accrued but unpaid paid time off, and any other amounts and benefits
which are then due to be paid or provided to Executive by the Company, but have not yet been paid or provided (as applicable). 
 1.4
“Affiliate” means any Person (including the Subsidiary) that directly or indirectly controls, is controlled by, or is under common control with, the Company. For purposes of this definition the term “control” with respect

 1.5 “Agreement Date” — see the introductory paragraph of this Agreement.

 1.6 “Agreement Term” means the period commencing on the Agreement Date and ending on the second anniversary of the

Agreement shall expire on a date specified in the Expiration Notice (the “Expiration Date”) that is not less than 12 months after the date the Expiration Notice is delivered to Executive; provided, however, that if a Change Date,
Imminent Control Change, Disaggregation or Significant Acquisition occurs before the Expiration Date specified in the Expiration Notice, then such Expiration Notice shall be void and of no further effect. If such Imminent Control Change or
Disaggregation does not culminate in a Change Date, then such Expiration Notice shall be reinstated and the Agreement shall expire on the date originally specified as the Expiration Date, or if later, the date the Imminent Control Change lapses or
the end of the sixtieth day after the Disaggregation. Notwithstanding anything herein to the contrary, the Agreement Term shall end at the end of the Severance Period if applicable, or if there is no Severance Period, the earliest of the following:
(a) the second anniversary of the Change Date, (b) eighteen (18) months after the Significant Acquisition, provided there has been no Change Date, (c) the end of the sixtieth day after the Disaggregation if there has been no
Change Date after the Disaggregation, or (d) the Termination Date.

of this definition; provided further, that for purposes of clause (2), if any 20% Owner of the Company other than the Company or any Company Plan becomes a 20% Owner by reason of an acquisition by the Company, and such 20% Owner of the Company
shall, after such acquisition by the Company, become the beneficial owner of any additional outstanding common shares of the Company or any additional outstanding Voting Securities of the Company (other than pursuant to any dividend reinvestment
plan or arrangement maintained by the Company) and such beneficial ownership is publicly announced, such additional beneficial ownership shall constitute a Change in Control; or 
 (b) Individuals who, as of the date hereof, constitute the Board (the “Incumbent Board”) cease for any reason to
constitute at least a majority of the Incumbent Board; provided, however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Company’s shareholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office

stock and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Corporate Transaction (including, without limitation, a
corporation which, as a result of such transaction, owns the Company or all or substantially all of the assets of the Company either directly or through one or more subsidiaries) in substantially the same proportions as their ownership immediately
prior to such Corporate Transaction of the outstanding common stock of Company and outstanding Voting Securities of the Company, as the case may be; 
 (ii) no SEC Person (other than the corporation resulting from such Corporate Transaction, and any Person which beneficially owned, immediately prior to such corporate Transaction, directly or indirectly, 20% or more
of the outstanding common stock of the Company or the outstanding Voting Securities of the Company, as the case may be) becomes a 20% Owner, directly or indirectly, of the then-outstanding common stock of the corporation resulting from such
Corporate Transaction or the combined voting power of the outstanding voting securities of such corporation; and 
 (iii)
individuals who were members of the Incumbent Board will constitute at least a majority of the members of the board of directors of the corporation resulting from such Corporate Transaction; or 
 (d) Approval by the Company’s shareholders of a plan of complete liquidation or dissolution of the Company, other than a plan of
liquidation or dissolution which results in the acquisition of all or substantially all of the assets of the Company by an affiliated company.

 2.2 Position and Duties

respect of the 12-month period immediately before the 

  

 11 

 
Applicable Trigger Date (such annual rate salary, the “Base Salary”). During the Post-Change Period, the Base Salary shall be reviewed no
more than 12 months after the last salary increase awarded to Executive prior to the Applicable Trigger Date and thereafter shall be reviewed and shall be increased at any time and from time to time as shall be substantially consistent with
increases in base salary awarded to peer executives of the Company generally. Base Salary shall not be reduced unless such reduction is part of a policy, program or arrangement applicable to peer executives of the Company (including peer executives
of any successor to the Company), and the term Base Salary as used in this Agreement shall refer to Base Salary as so increased. Any increase in Base Salary shall not limit or reduce any other obligation of the Company to the Executive under this
Agreement.

commences prior to the Termination Date and ends during the Post-Change Period. The amount of the Executive’s award opportunity in effect for any relevant period shall be determined taking into account any negative discretion exercised by the
Compensation Committee of the Board in establishing such opportunity. 
 (b) Annual Incentive during the Imminent Control
Change Period, Post-Significant Acquisition Period or Post-Disaggregation Period. Section 2.7(a) shall not apply during the Imminent Control Change Period, Post-Significant Acquisition Period or Post-Disaggregation Period.

 (a) Other Compensation and Benefits during the Post-Change Period. In addition to Base Salary and Annual Incentive, prior to the Termination Date the Company shall provide or cause to be provided, throughout
the Post-Change Period, the following other compensation and benefits to Executive, provided that, in no event shall such additional compensation and benefits (including incentives, measured with respect to long term and special incentives, to the
extent, if any, that such distinctions are applicable) be materially less favorable, in the aggregate, than those provided at any time after the Applicable Trigger Date to peer executives of the Company (including peer executives of any successor to
the Company) generally:

all incentive, savings and retirement Plans applicable to peer executives of the Company generally.

Company generally. 
 (vii) LTIP Awards. Awards under the LTIP shall be granted to Executive with aggregate target
opportunities not less than those granted to peer executives of the Company. 
 (b) Other Compensation and Benefits During
the Imminent Control Change Period, Post-Significant Acquisition Period or Post-Disaggregation Period. Section 2.8(a) shall not apply during Imminent Control Change Period, Post-Significant Acquisition Period or Post-Disaggregation Period.

 (i) Stock Options. 
 (A) Extinguished or Converted at Disaggregation. If so provided in the documents and instruments (“Disaggregation Documents”) pursuant to which the Disaggregation is effected, then all of
Executive’s Stock Options shall (I) be extinguished immediately prior to the 

  

 13 

 
Disaggregation for such consideration as is provided for in the Disaggregation Documents (but not less than the product of the number of Executive’s
vested Stock Options multiplied by the difference between the fair market value of Exelon stock immediately prior to the Disaggregation and the option exercise price), or (II) be converted into options to acquire stock of the Disaggregated
Entity or an affiliate thereof on a basis determined by the Company in good faith to preserve economic value. 
 (B)
Extinguished or Converted at Merger. If the Change in Control following the Disaggregation is a Merger, and if so provided in the agreement pursuant to which the Merger is effected, then all of Executive’s Company Stock Options that were
not extinguished or converted to options to acquire stock in the Disaggregated Entity or an affiliate shall (I) be extinguished immediately prior to the Change in Control for such consideration as is provided for Stock Options of peer
executives employed by the Company or an Affiliate, or (II) be converted into options to acquire stock of the corporation resulting from the Merger (“Merger Survivor”) or an affiliate thereof, on the same basis as Stock Options
of employees of the Company are converted. 
 (C) Stock Options after the Disaggregation. Executive’s

Section 4.3(b). 
 (ii) Performance Shares. 
 (A) Extinguished or Converted at Disaggregation. If so provided in the Disaggregation Documents, all of Executive’s

performance shares with respect to the Disaggregated Entity or an affiliate (on a basis determined by the Company in good faith to preserve economic value for the Executive); provided, however, that to the extent the Performance Shares are
considered deferred compensation that is subject to Section 409A of the Code, any consideration payable to Executive pursuant to clause (I) above shall be payable at the same time at which the Performance Shares would have been payable to
Executive, or at such other time as shall be permitted under Section 409A of the Code. 
 (B) Extinguished or
Converted at Merger. If the Change in Control following the Disaggregation is a Merger, and if so provided in the agreement pursuant to which the Merger is effected, then all of 

  

 14

(I) be extinguished immediately prior to the Change in Control for such consideration as is provided for Performance Shares of peer executives employed by the Company or an Affiliate, or (II) be converted into performance shares of the
Merger Survivor or an affiliate thereof, on the same basis as Performance Shares of employees of the Company are converted; provided, however, that to the extent the Performance Shares are considered deferred compensation that is subject to
Section 409A of the Code, any consideration payable to Executive pursuant to clause (I) above shall be payable at the same time at which the Performance Shares would have been payable to Executive, or at such other time as shall be
permitted under Section 409A of the Code. 
 (C) Performance Shares after the Disaggregation. Executive’s
unextinguished Performance Shares, whether or not they are converted into performance shares of the Disaggregated Entity or Merger Survivor, will continue to vest during the Post-Disaggregation Period, subject to Section 4.3(c).

 (A) Extinguished or Converted at Disaggregation. If so provided in the Disaggregation Documents, all of Executive’s Restricted Stock shall (I) be extinguished immediately prior to the Disaggregation
for an amount equal to the fair market value of an equal number of shares of Exelon common stock, or (II) shall be converted into restricted stock of the Disaggregated Entity or an affiliate (on a basis determined by the Company in good faith
to preserve economic value for the Executive).

 Article III. 
 Termination of Employment 
 3.1 Disability. 
 (a) During the Agreement Term, the Employer (or, if applicable, the Disaggregated Entity) may terminate Executive’s employment at any
time because of Executive’s Disability by giving Executive or his or her legal representative, as applicable, (i) written notice in accordance with Section 10.9 of the Company’s intention to terminate Executive’s employment
pursuant to this Section and (ii) a certification of Executive’s Disability by a physician selected by the Employer or its insurers, subject to the reasonable consent of Executive or Executive’s legal representative, which consent
shall not be unreasonably withheld or delayed. Executive’s employment shall terminate effective on the 30th day after Executive’s receipt of such notice (which such 30th day shall be deemed to be the “Disability Effective
Date”) unless, before such 30th day, Executive shall have resumed the full-time performance of Executive’s duties. 
 (b) “Disability” means any medically determinable physical or mental impairment that has lasted for a continuous period of not less than six months and can be expected to be permanent or of indefinite duration, and that
renders Executive unable to perform the duties required under this Agreement. 
 3.2 Death. Executive’s employment shall
terminate automatically upon Executive’s death during the Agreement Term. 
 3.3 Termination by the Company for Cause. During the
Post-Change Period, Post-Disaggregation Period, Imminent Control Change Period or Post-Significant Acquisition Period, the Company may terminate Executive’s employment (or cause Executive’s employment to be terminated) for Cause solely in
accordance with all of the substantive and procedural provisions of this Section 3.3. 
 (a) Definition of Cause.
“Cause” means any one or more of the following: 
 (i) the refusal to perform or habitual neglect in the performance
of the Executive’s duties or responsibilities, or of specific directives of the officer or other executive of the Company or any of its affiliates to whom the Executive reports which are not materially inconsistent with the scope and nature of
the Executive’s employment duties and responsibilities; 
 (ii) an Executive’s willful or reckless commission of
act(s) or omission(s) which have resulted in or are likely to result in, a material loss to, or material damage to the reputation of, the Company or any of its affiliates, or that compromise the safety of any employee or other person; 
 (iii) the Executive’s commission of a felony or any crime involving dishonesty or moral turpitude; 
  

 16 

 (iv) an Executive’s material violation of the Company’s or any of its
affiliates’ Code of Business Conduct (including the corporate policies referenced therein) which would constitute grounds for immediate termination of employment, or of any statutory or common-law duty of loyalty to the Company or any of its
affiliates; or 
 (v) any breach by the Executive of any one or more of the Restrictive Covenants. 
 For purposes of this Section, no act, or failure to act, on the part of the Executive shall be considered “willful” unless it is done, or
omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution
duly adopted by the Board or upon the instructions of the chief executive officer or a senior officer of the Company other than Executive or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be
done, by the Executive in good faith and in the best interests of the Company. 
 (b) Procedural Requirements for
Termination for Cause During a Post-Change Period. The Executive’s Termination of Employment for which the Notice of Termination is given during a Post-Change Period shall not be deemed to be for Cause under this Section 3.3 unless and
until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than 60% of the entire membership of the Board at a meeting of such Board called and held for such purpose (after
reasonable written notice of such meeting is provided to the Executive and the Executive is given an opportunity, together with counsel, to be heard before the Board), finding that, in the good faith opinion of the Board, the Executive’s acts,
or failure to act, constitutes Cause and specifying the particulars thereof in detail. 
 (c) Procedural Requirements for
Termination for Cause During a Post-Disaggregation Period. In the event Executive’s Termination of Employment is from a Disaggregated Entity in a Post-Disaggregation Period, the procedural requirements for termination for Cause in this
Section 3.3 shall be applied by substituting “Disaggregated Entity” for “Company,” “affiliate of the Disaggregated Entity” for “Affiliate,” and “Disaggregated Entity’s Board” for
“Board.” Further, the Company shall have no obligation to provide payments or benefits under Section 4.3 if the Board determines that the Company could have terminated Executive’s employment for Cause if the Executive had been
employed by the Company, such determination by the Board to be made as provided in Section 3.3(b) but applying the flush language at the end of Section 3.3(a) by substituting “Disaggregated Entity” for “Company” and
“Disaggregated Entity’s Board” for “Board.” 
 (d) Procedural Requirements for Termination for
Cause During the Imminent Control Change Period or Post-Significant Acquisition Period. The Executive’s Termination of Employment for which the Notice of Termination is given during the Imminent Control Change Period or Post-Significant
Acquisition Period shall not be deemed to be for Cause under this Section 3.3 unless and until there shall have been 

  

 17 

 
delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board,
finding that the Executive’s acts or failure to act, constitute Cause and specifying the particulars thereof in detail. Executive shall receive advance notice of such vote of the Board, but shall not have the right to appear in person or by
counsel before the Board. 
 3.4 Termination by the Executive for Good Reason. During the Post-Change Period, an Imminent Control
Change Period, a Post-Significant Acquisition Period or Post-Disaggregation Period, Executive may terminate his or her employment for Good Reason in accordance with the substantive and procedural provisions of this Section 3.4. 
 (a) Definition of Good Reason. For purposes of this Section 3.4, and subject to the provisions of subsections (b) through
(e), “Good Reason” means the occurrence of any one or more of the following actions or omissions prior to the Termination Date during the Post-Change Period, the Imminent Control Change Period, the Post-Significant Acquisition Period or
the Post-Disaggregation Period: 
 (i) a material reduction of the Executive’s salary, incentive compensation opportunity
or aggregate benefits unless such reduction is part of a policy, program or arrangement applicable to peer executives (including peer executives of any successor to the Company; 
 (ii) a material adverse reduction in the Executive’s position, duties, or responsibilities, other than in a Post-Significant
Acquisition period, and other than a change in the position or level of officer to whom the Executive reports or a change that is part of a policy, program or arrangement applicable to peer executives (including peer executives of any successor to
the Company); 
 (iii) the failure of any successor to the Company to assume this Agreement; 
 (iv) a relocation (other than in a Post-Significant Acquisition Period), by more than 50 miles of (I) the Executive’s primary
workplace, or (II) the principal offices of the Company or its successor (if such offices are the Executive’s workplace), in each case without Executive’s consent; provided, however, in both cases of (I) and (II) of this
Section 3.4(a)(iv), such new location is farther from Executive’s residence then the prior location; or 
 (v) a
material breach of this Agreement by the Company or its successor; 
 provided that the occurrence of a Disaggregation shall not be Good
Reason if the Executive retains substantially the same position (determined without regard to reporting requirements) with the Disaggregated Entity, with substantially the same compensation and benefits in the aggregate, as immediately prior to such
Disaggregation, notwithstanding Sections 3.4(a)(i), 3.4(a)(ii) and 3.4(a)(v). 
  

 18 

 (b) Application of “Good Reason” Definition During the Imminent Control
Change Period. During the Imminent Control Change Period, “Good Reason” shall not include the events or conditions described in Section 3.4(a)(i), 3.4(a)(ii) or 3.4(a)(iv) unless the Imminent Control Change Period culminates in a
Change Date. Further, if Executive’s Termination of Employment occurs during an Imminent Control Change Period that culminates in a Change Date, then, except as provided in Section 3.4(c), the definition of “Good Reason” shall be
applied as though Sections 2.1, 2.6, 2.7, and 2.8 were applicable during the Imminent Control Change Period prior to the Executive’s Termination of Employment. 
 (c) Special Conditions Relating to Good Reason During the Post-Disaggregation Period. If Executive is employed with the
Disaggregated Entity immediately following a Disaggregation, then (1) Section 3.4(a)(ii) shall apply with respect to the Executive’s position, duties or responsibilities as in effect on the day before the Disaggregation,
(2) subsection 3.4(a)(iv) shall apply with respect to relocations that are required after the Disaggregation and prior to the expiration of the Post-Disaggregation Period and shall be applied by substituting “Disaggregated Entity” for
“any successor to the Company,” and (3) all references in Section 3.4 to the Company or its successor shall be to the Disaggregated Entity or its successor. 
 (d) Limitations on Good Reason. Notwithstanding the foregoing provisions of this Section 3.4, no act or omission shall
constitute a material breach of this Agreement by the Company, nor grounds for “Good Reason”: 
 (i) unless the
Executive gives the Company a Notice of Termination at least 30 days’ prior to the Termination Date and the Company fails to cure such act or omission within the 30-day period; 
 (ii) if the Executive first acquired knowledge of such act or omission more than 90 days before the Executive gives the Company and the
Employer such Notice of Termination; or 
 (iii) if the Executive has consented in writing to such act or omission.

 (e) Notice by Executive. In the event of any Termination of Employment by Executive for Good Reason, Executive shall
as soon as practicable thereafter notify the Company and the Employer (and Disaggregated Entity, if applicable) of the events constituting such Good Reason by a Notice of Termination. Subject to the limitations in Section 3.4(d), a delay in the
delivery of such Notice of Termination shall not waive any right of Executive under this Agreement. 
  

 19 

 Article IV. 
 Company’s Obligations Upon Certain Terminations of Employment 
 4.1 Termination During the
Post-Change Period or Post-Significant Acquisition Period. If, during the Post-Change Period or Post-Significant Acquisition Period (other than any portion of any of such periods that are also a Post-Disaggregation Period), the Employer

of either such non-qualified plan; 
 (iv) Pension Enhancements. An amount payable under the SERP equal to the positive
difference, if any, between: 
 (1) the lump sum value of Executive’s benefit, if any, under the SERP, calculated as if

maintained by the Company in which the Executive is a participant (the “Pension Plan”, 
 (B) to the extent
age is relevant under the Pension Plan covering Executive, attained as of the Termination Date an age that is 2.0 years greater than Executive’s actual age and that includes the number of years of age credited to Executive pursuant to any other

 20 

 (C) to the extent that service is relevant under the Pension Plan covering Executive,

Executive, and 
 (D) received the benefits specified in Section 4.1(a)(ii) and 2.0 years of the benefits specified in

Executive by reason of the Termination of Employment; and 
 (vi) Multiple of Salary and Severance Incentive. An amount
equal to 2.99 times the sum of (x) Base Salary plus (y) the Severance Incentive. 
 (b) Termination during the
Post-Change Period or Post-Significant Acquisition Period: Stock Options. Each of the Executive’s stock options, stock appreciation rights or similar incentive awards granted under the LTIP (“Stock Options”) shall
(i) become fully vested, and (ii) remain exercisable until (1) the option expiration date for any such Stock Options granted prior to January 1, 2002 or (2) the fifth anniversary of the Termination Date or, if earlier, the
option expiration date for any such Stock Options granted on or after January 1, 2002; provided that this Section 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.

awarded to 

  

 21 

 
the Executive (i.e. as to which the current performance cycle has not elapsed) as of the Termination Date, shall become fully vested at the based on the
extent to which the performance goals established under the LTIP for such performance period are attained as of the last day of the year in which the Termination Date occurs.

(“Restricted Stock”) shall (except as specifically provided to the contrary in the applicable awards) lapse immediately and all such awards will become fully vested. 
 (e) Termination During the Post-Change Period or Post-Significant Acquisition Period: Continuation of Welfare Benefits. During the
Severance Period (and continuing through such later date as any Welfare Plan may specify), the Company shall continue to provide (or shall cause the continued provision) to Executive and Executive’s family welfare benefits under the Welfare
Plans to the same extent as if Executive had remained employed during the Severance Period. Such provision of welfare benefits shall be subject to the following: 
 (i) In determining benefits applicable under such Welfare Plans, the Executive’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 the Executive’s Base Salary and Annual Incentive. 
 (ii) The cost of such welfare benefits to Executive and family under this Section 4.1(e) shall not exceed the cost of such benefits to peer executives who are actively employed after the Termination Date.

 (iii) The Executive’s rights under this Section 4.1(e) shall be in addition to and not in lieu of any
post-termination continuation coverage or conversion rights the Executive may have pursuant to applicable law, including, without limitation, continuation coverage required by Section 4980B of the Code. 
 (iv) If the Executive has, as of the last day of the Severance Period, attained age 50 and completed at least 10 years of service (or any
lesser age and service requirement then in effect under the Exelon Corporation Severance Benefit Plan or any successor plan), the Executive shall be entitled to the retiree benefits provided under any Welfare Plan of the Company; provided, however,
that for purposes hereof, any years of credited service granted to the Executive in any other written plan or agreement between Executive and the Company shall be taken into account. For purposes of determining eligibility for (but not the time of
commencement of) such retiree benefits, the Executive 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 the Executive would have attained on the last day of the Severance Period. 
  

 22 

 Notwithstanding the foregoing, if the Executive obtains a specific type of coverage under welfare plan(s)
sponsored by another employer of Executive (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 Executive is
so eligible), then the Company shall not be obligated to provide any such specific type of coverage. The Executive shall promptly notify the Company of any such coverage. 
 (f) Termination during the Post-Change Period or Post-Significant Acquisition Period: Outplacement. To the extent actually incurred
by Executive, the Company shall pay or cause to be paid on behalf of Executive, as incurred, all reasonable fees and costs charged by a nationally recognized outplacement firm selected by the Executive for outplacement services provided up to 12
months after the Termination Date. No cash shall be paid in lieu of such fees and costs. 
 (g) Termination during the
Post-Change Period or Post-Significant Acquisition Period: Indemnification. The Executive shall be indemnified and held harmless by the Company to the greatest extent permitted under applicable law as the same now exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification than was permitted prior to such amendment) and the Company’s by-laws as such exist on the Applicable
Trigger Date if the Executive 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 the Executive is or was, or had agreed to
become, a director, officer, employee, agent, or fiduciary of the Company or any other entity which the Executive 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 the Executive or to which the Executive may become subject for any reason; provided, that the Company shall not be required to indemnify the Executive in
connection with any proceeding initiated by the Executive, including a counterclaim or cross claim, unless such proceeding was authorized by the Company and Executive fully cooperates in the investigation and defense of such Proceeding. A Proceeding
shall not include any proceeding to the extent it concerns or relates to a matter described in Section 6.1(a) (concerning reimbursement of certain costs and expenses). Upon receipt from Executive of (i) a written request for an advancement
of expenses, which Executive reasonably believes will be subject to indemnification hereunder and (ii) a written undertaking by Executive to repay any such amounts if it shall ultimately be determined that Executive is not entitled to
indemnification under this Agreement or otherwise, the Company shall, to the extent permitted by applicable law, advance such expenses to Executive or pay such expenses for Executive, all in advance of the final disposition of any such matter.

 (h) Termination during the Post-Change Period or Post-Significant Acquisition Period: Directors’ and Officers’
Liability Insurance. For a period of six years after the Termination Date (or for any known longer applicable statute of 

  

 23 

 
limitations period), the Company shall provide Executive 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 senior executive officers and directors of the Company on the Applicable Trigger Date. 
 4.2 Termination During an Imminent Control Change Period. If, during an Imminent Control Change Period, Executive has a Termination of Employment that would entitle Executive to benefits under Section 4 of
the Exelon Corporation Senior Management Severance Plan or its successor, then the Company shall, prior to the occurrence of a Change Date, provide Executive any benefits to which Executive may be entitled under Section 4 (i.e., non-change in
control) of the Exelon Corporation Senior Management Severance Plan or its successor. If, during an Imminent Control Change Period, the Employer terminates Executive’s employment other than for Disability and other than for Cause, or if
Executive terminates employment for Good Reason then subject to the preceding sentence, unless such Termination of Employment occurred during the Post-Significant Acquisition Period, the Company’s sole obligations to Executive under Articles II
and IV shall be as set forth in this Section 4.2. The Company’s obligations to Executive under this Section 4.2 shall be reduced by any amounts or benefits paid or provided pursuant to the Exelon Corporation Senior Management
Severance Plan (whether under Section 4 thereof or any other provision) or any successor thereto. If Executive’s Termination of Employment occurred during any portion of an Imminent Control Change Period that is also a Post-Significant
Acquisition Period, the Company’s obligations to Executive, if any, shall be determined under Section 4.1. 
 (a)
Termination During an Imminent Control Change Period: Cash Severance Payments. If the Imminent Control Change Period culminates in a Change Date, the Company shall pay (or cause to be paid) to Executive the amounts described in
Section 4.1(a)(i) through (vi). Such amounts shall be paid to Executive as described in Section 4.4, 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) Termination During an Imminent Control Change Period: Vested Stock Options.
Executive’s Stock Options, to the extent vested on the Termination Date, 
 (i) will not expire (unless such Stock
Options would have expired had Executive 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 Plan, 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 Executive’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 Executive’s vested Stock Options could otherwise be exercised
under the terms of the applicable grant agreement or Plan (but in no case shall any Stock Options remain exercisable after the date on which such Stock Options would have expired if Executive had remained an employee of the Company). 
  

 24 

 If the Imminent Control Change Period culminates in a Change Date, then effective upon the Change Date,
Executive’s Stock Options, to the extent vested on the Termination Date, may be exercised in whole or in part by the Executive at any time until (1) the option expiration date for such Stock Options granted prior to January 1, 2002 or
(2) the earlier of the fifth anniversary of the Change Date or the option expiration date for such Stock Options granted on or after January 1, 2002; provided that this Section 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. 
 (c) Termination During an Imminent
Control Change Period: Unvested Stock Options. Executive’s Stock Options that are not vested on the Termination Date 
 (i) will not expire (unless such Stock Options would have expired had Executive 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 after the expiration of the period
for post-termination exercise under the terms of the applicable Stock Option Agreement. 
 If the Imminent Control Change lapses without a
Change Date, such unvested Stock Options will thereupon expire. 
 If the Imminent Control Change culminates in a Change Date, then
immediately prior to the Change Date, such unvested Stock Options shall become fully vested, and may thereupon be exercised in whole or in part by the Executive at any time until (1) the option expiration date for such Stock Options granted
prior to January 1, 2002 or (2) the earlier of the fifth anniversary of the Change Date, or the option expiration date for such Stock Options granted on or after January 1, 2002; provided that this Section 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)
Termination During an Imminent Control Change Period: Performance Shares. Executive’s Performance Shares granted under the Exelon Performance Share 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 of the Exelon Corporation Senior
Management Severance Plan. If the Imminent Control Change Period culminates in a Change Date: 
 (1) All Performance Shares
granted to the Executive under the Exelon Performance Share Program under the LTIP, which, as of the Termination Date, have been earned by and awarded to the Executive, shall become fully vested at the actual earned level on the Change Date, and

  

 25 

 (2) All of the Performance Shares granted to the Executive under the Exelon Performance
Share Program under the LTIP which, as of the Termination Date, have not been earned by and awarded to the Executive shall become fully vested on the Change Date at the LTIP Target Level. 
 (e) Termination During an Imminent Control Change Period: Restricted Stock. Executive’s unvested 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. 
 If the Imminent Control Change Period lapses without a Change Date, such unvested Restricted Stock shall thereupon be forfeited. 
 If the Imminent Control Change Period culminates in a Change Date, then immediately prior to the Change Date, Executive’s Restricted Stock shall
(except as specifically provided to the contrary in the award) become fully vested. 
 (f) Termination During an Imminent
Control Change Period: Continuation of Welfare Benefits. The Company shall continue to provide to Executive and Executive’s family welfare benefits (other than any severance pay that may be considered a welfare benefit) during the Imminent
Change Period which are at least as favorable as welfare benefits under the most favorable Welfare Plans of the Company applicable with respect to peer executives who are actively employed after the Termination Date and their families; subject to
the following: 
 (i) In determining benefits applicable under such Welfare Plans, the Executive’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 the Executive’s Base Salary and Annual Incentive; 
 (ii) The cost of such welfare benefits to Executive and family under this Section 4.2(f) shall not exceed the cost of such benefits
to peer executives who are actively employed after the Termination Date. 
 (iii) Executive’s rights under this
Section 4.2(f) shall be in addition to and not in lieu of any post-termination continuation coverage or conversion rights the Executive may have pursuant to applicable law, including, without limitation, continuation coverage required by
Section 4980B of the Code. 
 If the Imminent Control Change Period lapses without a Change Date, welfare benefit plan coverage under
this Section 4.2(f) shall thereupon cease, subject to Executive’s rights, if any, to continued coverage under a Welfare Plan, Section 4 of the Exelon 

  

 26 

 
Corporation Senior Management Severance Plan, or applicable law. If the Imminent Control Change Period culminates in a Change Date, then for the remainder of
the Severance Period (and continuing through such later date as any Welfare Plan may specify), the Company shall continue to provide Executive and Executive’s family welfare benefits as described in, and subject to the limitations of
Section 4.1(e). 
 Notwithstanding the foregoing, if the Executive obtains a specific type of coverage under welfare plan(s) sponsored by
another employer of Executive (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 Executive is so eligible),
then the Company shall not be obligated to provide such any specific type of coverage. The Executive shall immediately notify the Company of any such coverage. 
 (g) Termination During an Imminent Control Change Period: Outplacement. To the extent actually incurred by Executive, the Company
shall pay or cause to be paid on behalf of Executive, as incurred, all reasonable fees and costs charged by a nationally recognized outplacement firm selected by the Executive for outplacement services provided up to 12 months after the Termination
Date. No cash shall be paid in lieu of such fees and costs. 
 (h) Termination During an Imminent Control Change Period:
Indemnification. The Executive shall be indemnified and held harmless by the Company to the same extent as provided in Section 4.1(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 Executive as provided in Section 4.1(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. 
 4.3 Termination During a Post-Disaggregation Period. If, during a Post-Disaggregation Period the Disaggregated Entity terminates Executive’s employment other than for Cause or Disability, or if Executive
terminates employment for Good Reason, the Company’s sole obligations to Executive under Articles II and IV shall be as set forth in this Section 4.3, subject to Section 3.3(c), but only to the extent not provided by the Disaggregated
Entity. 
 (a) Termination During a Post-Disaggregation Period: Cash Severance Payments. The Company shall pay
Executive the amounts described in Section 4.1(a), as provided in Section 4.4. 
 (b) Termination During a
Post-Disaggregation Period: Stock Options. All of Executive’s Stock Options granted prior to the Disaggregation that have not expired, whether or not converted to options or stock of the Disaggregated Entity or Merger Survivor, shall be
fully vested, and may be exercised in whole or in part by the Executive 

  

 27 

 
at any time until (1) the remaining option expiration date for such Stock Options granted prior to January 1, 2002 and (2) the earlier of the
fifth anniversary of the Termination Date or the option expiration date for such Stock Options granted on or after January 1, 2002; provided that this Section 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. 
 (c) Termination During a Post-Disaggregation Period:
Performance Shares. Executive’s Performance Shares granted prior to the Disaggregation, whether or not earned by and awarded to the Executive as of the Disaggregation, and whether or not converted to performance shares of the Disaggregated
Entity or the Merger Survivor, shall become fully vested (at the earned level for Performance Shares earned and awarded, and at the target level for any converted performance shares not yet earned and awarded) on the Termination Date. 
 (d) Termination During a Post-Disaggregation Period: Restricted Stock. Executive’s unvested Restricted Stock, whether or not
converted to restricted stock of the Disaggregated Entity or Merger Survivor, shall become fully vested on the Termination Date. 
 (e) Termination During a Post-Disaggregation Period: Continuation of Welfare Benefits. Until the end of the Severance Period, the Company shall continue to provide to Executive and Executive’s family welfare benefits with the
same rights in relation to continuation coverage, status in relation to other employer benefits, scope and cost as described in Section 4.1(e); provided that, to the extent Executive is eligible for post-termination continuation coverage under
the plans of the Disaggregated Entity, whether pursuant to Section 4980B of the Code or otherwise, the continued coverage required hereunder shall be provided under the plans of the Disaggregated Entity (and the Company shall reimburse the cost
to Executive of such coverage). 
 (f) Termination During a Post-Disaggregation Period: Outplacement. To the extent
actually incurred by Executive, the Company shall pay or cause to be paid on behalf of Executive, as incurred, all reasonable fees and costs charged by a nationally recognized outplacement firm selected by the Executive for outplacement services

 4.4
Timing of Severance Payments. Unless otherwise specified herein, the amounts described in Section 4.1(a)(i) shall be paid within 30 business days of the Termination Date (or 

  

 28 

 
eight days after the date on which Executive executes and returns the Waiver and Release (as defined in Section 4.5), if later), and such amounts shall
be considered “short-term deferrals” with the meaning of Section 409A of the Code. The amounts described in Sections 4.1(a)(ii), (iii), (iv) and (v) shall be paid in accordance with the applicable Incentive Plan, deferred
compensation plan or SERP and, if applicable, Executive’s distribution election thereunder as of the Termination Date (or, if no affirmative election is in effect as of such date, the default election as of such date). The severance payments
described in Section 4.1(a)(vi) shall be paid as follows: 
 (a) Beginning no later than the second paydate which occurs
after the Termination Date (or eight days after the date on which Executive executes and returns the Waiver and Release, if later), the Company shall make periodic payments to the Executive according to the Company’s normal payroll practices at
a monthly rate equal to 1/12 of the sum of (i) the Executive’s Base Salary in effect as of the Termination Date plus (ii) the Severance Incentive; and 
 (b) Within 30 business days of the second anniversary of the Termination Date, the Company shall pay Executive a cash lump sum equal to
the difference between the total Severance Payment less the total amount paid pursuant to normal payroll practices under Section 4.4(a); 
 provided
that in the event the Company determines that Executive is a “specified employee,” within the meaning of Section 409A of the Code, and that certain of the payments made to Executive under Section 4.1(a)(vi) constitute the payment
of deferred compensation that is subject to Section 409A of the Code, then any of such payments that pursuant to this Section 4.4 would be paid prior to the six-month anniversary of Executive’s Termination Date shall, to the extent
required by Section 409A of the Code, be delayed and be paid to Executive on the six-month anniversary of Executive’s Termination Date. The Stock Options, Performance Shares and Restricted Stock awards shall be paid in accordance with the
LTIP and the applicable award agreements; provided that, in the event the Company determines that Executive is a “specified employee,” within the meaning of Section 409A of the Code, and that an award constitutes the payment of
deferred compensation that is subject to Section 409A of the Code, then any payment of such award pursuant to this Section 4.4 that would be paid prior to the six-month anniversary of Executive’s Termination Date shall, to the extent
required by Section 409A of the Code, be delayed and paid to Executive on the six-month anniversary of Executive’s Termination Date. The in-kind benefits and reimbursements provided under each of Sections 4.1(e), 4.1(g), 4.2(f), 4.2(h),
4.3(e) and 4.4(g) 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. 
 4.5 Waiver and Release. Notwithstanding anything herein to the contrary, the Company shall have no
obligation to Executive under Article IV or Article V unless and until Executive executes a release and waiver of Company and its Affiliates, in substantially the same form as attached hereto as Exhibit A, or as otherwise mutually acceptable
(the “Waiver and Release”), returns such Waiver and Release to the Company within 45 days after the Termination Date and does not revoke the Waiver and Release within any permitted revocation period. 
  

 29 

 4.6 Breach of Covenants. If a court determines that Executive has breached any non-competition,
non-solicitation, confidential information or intellectual property covenant entered into between Executive and Company, the Company shall not be obligated to pay or provide any severance or benefits under Articles IV or V, all unexercised Stock
Options shall terminate as of the date of the breach, and all Restricted Stock shall be forfeited as of the date of the breach. 
 4.7
Termination by the Company for Cause. If the Company (or Affiliate or, if applicable, the Disaggregated Entity) terminates Executive’s employment for Cause during the Post-Change Period, the Imminent Control Change Period, the
Post-Significant Acquisition Period, or the Post-Disaggregation Period, the Company’s sole obligation to Executive under Articles II, IV, and V shall be to pay Executive, pursuant to the Company’s then-effective Plans, a lump-sum cash
amount equal to all Accrued Obligations determined as of the Termination Date. The remaining applicable provisions of this Agreement (including the restrictive covenants in Article VIII) shall continue to apply. 
 4.8 Termination by Executive Other Than for Good Reason. If Executive elects to retire or otherwise terminate employment during the Post-Change
Period, the Imminent Control Change Period, the Post-Significant Acquisition Period, or the Post-Disaggregation Period, other than for Good Reason, Disability or death, the Company’s sole obligation to Executive under Articles II, IV, and V
shall be to pay Executive, pursuant to the Company’s then-effective Plans, a lump-sum cash amount equal to all Accrued Obligations determined as of the Termination Date. The remaining provisions of this Agreement (including the restrictive
covenants in Article VIII) shall continue to apply. 
 4.9 Termination by the Company for Disability. If the Company (or Disaggregated
Entity, if applicable) terminates Executive’s employment by reason of Executive’s Disability during a Post-Change Period, Imminent Control Change Period that culminates in a Change Date, Post-Significant Acquisition Period or
Post-Disaggregation Period, the Company’s sole obligation to Executive under Articles II, IV, and V shall be as follows, and such obligations shall be reduced by amounts paid or provided by the Disaggregated Entity: 
 (a) to pay Executive, a lump-sum cash amount equal to the sum of amounts specified in Section 4.1(a)(i) and (ii) determined as
of the Termination Date, 
 (b) to pay Executive the amounts described in Section 4.1(a)(iii) in accordance with the
applicable deferred compensation plan and Executive’s distribution election thereunder as of the Termination Date (or, if no affirmative election is in effect as of such date, the default election as of such date) and 
 (c) to provide Executive disability and other benefits after the Termination Date that are not less than the most favorable of such
benefits then available under Plans of the Company to disabled peer executives of the Company in effect immediately before the Termination Date. 
 The
remaining provisions of this Agreement (including the restrictive covenants in Article VIII) shall continue to apply. 
  

 30 

 4.10 Upon Death. If Executive’s employment is terminated by reason of Executive’s death
during a Post-Change Period, Imminent Control Change Period that culminates in a Change Date, Post-Significant Acquisition Period or Post-Disaggregation Period, the Company’s sole obligations to Executive and Executive’s Beneficiary under
Articles II, IV, and V shall be as follows, and such obligations shall be reduced by amounts paid or provided by the Disaggregated Entity: 
 (a) to pay Executive’s Beneficiary, pursuant to the Company’s then-effective Plans or, if the timing of payment is not governed by the terms of a Plan, within 30 days after the date of Executive’s
death, a lump-sum cash amount equal to all Accrued Obligations; and 
 (b) to provide Executive’s Beneficiary survivor
and other benefits that are not less than the most favorable of such benefits then available under Plans of the Company to surviving families of peer executives of the Company in effect immediately before the Executive’s death, including
retiree health care coverage under any Welfare Plan of the Company that provides such coverage without regard to whether the Executive had satisfied the eligibility requirements for such coverage as of the date of his or her death. 
 4.11 Sole and Exclusive Obligations. The obligations of the Company under this Agreement, as amended and restated effective January 1, 2009,
with respect to any Termination of Employment of the Executive during the Post-Change Period, Imminent Control Change Period, Post-Significant Acquisition Period, or Post-Disaggregation Period shall, except as provided in Section 4.2, supersede
any severance obligations of the Company in any other plan of the Company or agreement between Executive and the Company, including, without limitations, the Exelon Corporation Senior Management Severance Plan under Section 4 or any other
provision thereof, or any other plan or agreement (including an offer of employment or employment contract) of the Company or any Affiliates which provides for severance benefits. In the event of any inconsistency, ambiguity or conflict between the
terms of such other plan of the Company or agreement between Executive and the Company and this Agreement with respect to any severance obligations of the Company (other than obligations with respect to credited service under the SERP in any
agreement other than a prior Change in Control Agreement entered into by and among Executive, Unicom Corporation, Commonwealth Edison Company or PECO Energy Company), this Agreement shall govern. 
 Article V. 
 Certain Additional
Payments by the Company 
 5.1 Gross-Up Payment. 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 Executive pursuant to Article II or Article IV of this Agreement 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 Company shall, subject to Section 5.2, pay or cause to be paid a tax
gross-up payment (“Gross-Up Payment”) with respect to all such Excise Taxes and other Taxes on the Gross-Up Payment. The Gross-Up Payment shall be an amount equal to the product of 
  

 31 

 (a) The amount of the Excise Taxes (calculated at the effective marginal rates of all
federal, state, local, foreign or other law), 
 multiplied by 
 (b) A fraction (the “Gross-Up Multiple”), the numerator or which is one (1.0), and the denominator of which is one
(1.0) minus the lesser of (i) the sum, expressed as a decimal fraction, of the effective marginal rates of any Taxes and any Excise Taxes applicable to the Gross-Up Payment or (ii) .80, it being intended that the Gross-Up Multiple
shall in no event exceed five (5.0). If different rates of tax are applicable to various portions of a Gross-Up Payment, the weighted average of such rates shall be used. For purposes of this Section, Executive shall be deemed to be subject to the
highest effective marginal rate of Taxes. 
 The Gross-Up Payment is intended to compensate Executive for all such Excise Taxes and any other Taxes payable
by Executive with respect to the Gross-Up Payment. The Company shall pay or cause to be paid the Gross-Up Payment to Executive within thirty (30) days of the calculation of such amount, but in no event after the Executive makes payment to the
IRS of such Excise Taxes. 
 5.2 Limitation on Gross-Up Payments. 
 (a) To the extent possible, any payments or other benefits to Executive pursuant to Article II and Article IV of this Agreement shall be
allocated as consideration for Executive’s entry into the covenants of Article VIII. 
 (b) Notwithstanding any other
provision of this Article V, if the aggregate amount of the Potential Parachute Payments that, but for this Section 5.2, would be payable to Executive, does not exceed 110% of Floor Amount (as defined below), then no Gross-Up Payment shall
be made to Executive and the aggregate amount of Potential Parachute Payments payable to Executive (commencing with payments under Section 4.1(a)(vi)) shall be reduced (but not below the Floor Amount) to the largest amount which would both
(i) not cause any Excise Tax to be payable by Executive and (ii) not cause any Potential Parachute Payments to become nondeductible by the Company by reason of Section 280G of the Code (or any successor provision). For purposes of the
preceding sentence, “Floor Amount” means the greatest pre-tax amount of Potential Parachute Payments that could be paid to Executive without causing Executive to become liable for any Excise Taxes in connection therewith.

 5.3 Additional Gross-up Amounts. If, for any reason (whether pursuant to subsequently enacted provisions of the Code, final
regulations or published rulings of the IRS, or a final judgment of a court of competent jurisdiction) the Company’s independent auditors later determine that the amount of Excise Taxes payable by Executive is greater than the amount initially
determined pursuant to Section 5.1, then the Company shall, subject to Sections 5.2 and 5.4, pay Executive, within thirty (30) days of such determination, or pay to the IRS as required by applicable law, an amount (which shall also be
deemed a Gross-Up Payment) equal to the product of: 
 (a) the sum of (i) such additional Excise Taxes and (ii) any
interest, penalties, expenses or other costs incurred by Executive as a result of having taken a position in accordance with a determination made pursuant to Section 5.1 or 5.4, 
  

 32 

 multiplied by 
 (b) the Gross-Up Multiple. 
 5.4 Amount Increased or Contested. 
 (a) Executive shall notify the Company in writing (an
“Executive’s Notice”) of any claim by the IRS or other taxing authority (an “IRS Claim”) that, if successful, would require the payment by Executive of Excise Taxes in respect of Potential Parachute Payments in
an amount in excess of the amount of such Excise Taxes determined in accordance with Section 5.1. Executive’s Notice shall include the nature and amount of such IRS Claim, the date on which such IRS Claim is due to be paid (the
“IRS Claim Deadline”), and a copy of all notices and other documents or correspondence received by Executive in respect of such IRS Claim. Executive shall give the Executive’s Notice as soon as practicable, but no later than
the earlier of (i) 10 days after Executive first obtains actual knowledge of such IRS Claim or (ii) five days before the IRS Claim Deadline; provided, however, that any failure to give such Executive’s Notice shall affect the
Company’s obligations under this Article only to the extent that the Company is actually prejudiced by such failure. If at least one business day before the IRS Claim Deadline the Company shall: 
 (i) deliver to Executive a written certificate from the Company’s independent auditors (“Company Certificate”) to
the effect that, notwithstanding the IRS Claim, the amount of Excise Taxes, interest or penalties payable by Executive is either zero or an amount less than the amount specified in the IRS Claim, 
 (ii) pay to Executive, or to the IRS as required by applicable law, an amount (which shall also be deemed a Gross-Up Payment) equal to
difference between the product of (A) amount of Excise Taxes, interest and penalties specified in the Company Certificate, if any, multiplied by (B) the Gross-Up Multiple, less the portion of such product, if any, previously paid to
Executive by the Company, and 
 (iii) direct Executive pursuant to Section 5.4(d) to contest the balance of the IRS
Claim, 
 then Executive shall pay only the amount, if any, of Excise Taxes, interest and penalties specified in the Company Certificate. In
no event shall Executive pay an IRS Claim earlier than 30 business days after having given an Executive’s Notice to the Company (or, if sooner, the IRS Claim Deadline). 
  

 33 

 (b) At any time after the payment by Executive of any amount of Excise Taxes, other Taxes
or related interest or penalties in respect of Potential Parachute Payments (including any such amount equal to or less than the amount of such Excise Taxes specified in any Company Certificate, or IRS Claim), the Company may in its discretion
require Executive to pursue a claim for a refund (a “Refund Claim”) of all or any portion of such Excise Taxes, other Taxes, interest or penalties as may be specified by the Company in a written notice to Executive. 
 (c) If the Company notifies Executive in writing that the Company desires Executive to contest an IRS Claim or to pursue a Refund Claim,
Executive shall: 
 (i) give the Company all information that it reasonably requests in writing from time to time relating to
such IRS Claim or Refund Claim, as applicable, 
 (ii) take such action in connection with such IRS Claim or Refund Claim (as
applicable) as the Company reasonably requests in writing from time to time, including accepting legal representation with respect thereto by an attorney selected by the Company, subject to the approval of Executive (which approval shall not be
unreasonably withheld or delayed), 
 (iii) cooperate with the Company in good faith to contest such IRS Claim or pursue such
Refund Claim, as applicable, 
 (iv) permit the Company to participate in any proceedings relating to such IRS Claim or Refund
Claim, as applicable, and 
 (v) contest such IRS Claim or prosecute Refund Claim (as applicable) to a determination before
any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company may from time to time determine in its discretion. 
 The Company shall control all proceedings in connection with such IRS Claim or Refund Claim (as applicable) and in its discretion may cause Executive to pursue or forego any and all administrative appeals,
proceedings, hearings and conferences with the Internal Revenue Service or other taxing authority in respect of such IRS Claim or Refund Claim (as applicable); provided that (i) any extension of the statute of limitations relating to payment of
taxes for the taxable year of Executive relating to the IRS Claim is limited solely to such IRS Claim, (ii) the Company’s control of the IRS Claim or Refund Claim (as applicable) shall be limited to issues with respect to which a Gross-Up
Payment would be payable, and (iii) Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or other taxing authority. 
 (d) The Company may at any time in its discretion direct Executive to (i) contest the IRS Claim in any lawful manner or (ii) pay
the amount specified in an IRS Claim and pursue a Refund Claim; provided, however, that if the Company directs Executive to pay an IRS Claim and pursue a Refund Claim, the Company shall advance the amount of such payment to Executive on an
interest-free basis and shall indemnify Executive, on an after-tax basis, for any Excise Tax or income tax, including related interest or penalties, imposed with respect to such advance. 
  

 34 

 (e) The Company shall pay directly all legal, accounting and other costs and expenses
(including additional interest and penalties) incurred by the Company or Executive in connection with any IRS Claim or Refund Claim, as applicable, and shall indemnify Executive, on an after-tax basis, for any Excise Tax or income tax, including
related interest and penalties, imposed as a result of such payment of costs and expenses. 
 5.5 Refunds. If, after the receipt by
Executive or the IRS of any payment or advance of Excise Taxes or other Taxes by the Company pursuant to this Article, Executive receives any refund with respect to such Excise Taxes, Executive shall (subject to the Company’s complying with any
applicable requirements of Section 5.4) promptly pay the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 5.4 or receipt by the IRS of an amount paid by the Company on behalf of the Executive pursuant to Section 5.4, a determination is made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to contest such determination within 30 days after the Company receives written notice of such determination, then such advance shall be forgiven and shall not be required to
be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. Any contest of a denial of refund shall be controlled by Section 5.4(d). 
 Article VI. 
 Expenses, Interest and
Dispute Resolution 
 6.1 Enforcement and Late Payments. 
 (a) If, after the Agreement Date, Executive incurs reasonable legal fees or other expenses (including arbitration costs and expenses under
Section 6.3) in an effort to secure, preserve, or obtain benefits under this Agreement, the Company shall, regardless of the outcome of such effort, reimburse Executive (in accordance with Section 6.1(b)) for such fees and expenses.

 (b) Reimbursement of legal fees and expenses and gross-up payments shall be made on a current basis, promptly after
Executive’s written submission of a request for reimbursement together with evidence that such fees and expenses were incurred. 
 (c) If Executive does not prevail (after exhaustion of all available judicial remedies) in respect of a claim by Executive or by the Company hereunder, and the Company establishes before a court of competent jurisdiction by clear and
convincing evidence that Executive had no reasonable basis for Executive’s claim hereunder, or for Executive’s response to the Company’s claim hereunder, or that Executive acted in bad faith, no further reimbursement for legal fees
and expenses shall be due to Executive in respect of such claim and Executive shall refund any amounts previously reimbursed hereunder with respect to such claim. 
  

 35 

 6.2 Interest. If the Company does not pay any cash amount due to Executive under this Agreement
within three business days after such amount first became due and owing, interest shall accrue on such amount from the date it became due and owing until the date of payment at an annual rate equal to 200 basis points above the base commercial
lending rate published in The Wall Street Journal in effect from time to time during the period of such nonpayment; provided that the Executive shall not be entitled to interest on any Gross Up Payment. 
 6.3 Arbitration. Any dispute, controversy or claim between the parties hereto arising out of or in connection with or relating to this
Agreement (other than disputes related to Article V or to an alleged breach of the covenant contained in Article VIII) or any breach or alleged breach thereof, or any benefit or alleged benefit hereunder, shall be settled by 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 labor disputes. Either party may invoke the right to
arbitration. The arbitrator shall be selected by means of the parties striking alternatively from a panel of seven arbitrators supplied by the Chicago office of AAA. The arbitrator shall have the authority to interpret and apply the provisions of
this Agreement, consistent with Section 10.12 below. The decision of the arbitrator shall be final and binding upon the parties and a judgment thereon may be entered in the highest court of a forum, state or federal, having jurisdiction. The
expenses of the arbitration shall be borne according to Section 6.1. 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 6.3 or elsewhere in this Agreement, either party may bring an action in the District Court of Cook County, or the United States District Court for the Northern
District of Illinois, if jurisdiction there lies, in order to maintain the status quo ante of the parties. The “status quo ante” is defined as the last peaceable, uncontested status between the parties. However, neither the party bringing
the action nor the party defending the action thereby waives its right to arbitration of any dispute, controversy or claim arising out of or in connection or relating to this Agreement. Notwithstanding anything to the contrary contained in this
Section 6.3 or elsewhere in this Agreement, either party may seek relief in the form of specific performance, injunctive or other equitable relief in order to enforce the decision of the arbitrator. The parties agree that in any arbitration
commenced pursuant to this Agreement, the parties shall be entitled to such discovery (including depositions, requests for the production of documents and interrogatories) as would be available in a federal district court pursuant to Rules 26
through 37 of the Federal Rules of Civil Procedure. In the event that either party fails to comply with its discovery obligations hereunder, the arbitrator shall have full power and authority to compel disclosure or impose sanctions to the full
extent of Rule 37 of the Federal Rules of Civil Procedure.

 Article VII. 
 No Set-off or Mitigation 
 7.1 No Set-off by Company. Executive’s right to receive when
due the payments and other benefits provided for under this Agreement is absolute, unconditional and subject to no setoff, counterclaim or legal or equitable defense; provided, however that the Company shall have no further obligation to pay or
provide severance benefits under Article II, Article IV or Article V if at any time it determines, in accordance with the procedural requirements in Section 3.3, that in the course of his or her employment the Executive engaged in conduct
described in Section 3.3(a)(iii) or the last clause of Section 3.3(a)(iv), and all incentive compensation paid or payable hereunder shall be subject to any officer compensation recoupment policy as in effect on the Change Date. Time is of
the essence in the performance by the Company of its obligations under this Agreement. Any claim which the Company may have against Executive, whether for a breach of this Agreement or otherwise, shall be brought in a separate action or proceeding
and not as part of any action or proceeding brought by Executive to enforce any rights against the Company under this Agreement. 
 7.2 No
Mitigation. Executive shall not have any duty to mitigate the amounts payable by the Company under this Agreement by seeking new employment or self-employment following termination. Except as specifically otherwise provided in this Agreement,
all amounts payable pursuant to this Agreement shall be paid without reduction regardless of any amounts of salary, compensation or other amounts which may be paid or payable to Executive as the result of Executive’s employment by another
unaffiliated employer or self-employment. 
 Article VIII. 
 Restrictive Covenants 
 8.1 Confidential Information. The Executive
acknowledges that in the course of performing services for the Companies and Affiliates, he or she may create (alone or with others), learn of, have access to and receive Confidential Information. Confidential Information shall not include:
(i) information that is or becomes generally known through no fault of Executive; (ii) information received from a third party outside of the Company that was disclosed without a breach of any confidentiality obligation; or
(iii) information approved for release by written authorization of the Company. The Executive recognizes that all such Confidential Information is the sole and exclusive property of the Company and its Affiliates or of third parties which the
Company or Affiliate is obligated to keep confidential, that it is the Company’s policy to keep all such Confidential Information confidential, and that disclosure of Confidential Information would cause damage to the Company and its
Affiliates. The Executive agrees that, except as required by the duties of Executive’s employment with the Company or any of its Affiliates and except in connection with enforcing the Executive’s rights under this Agreement or if compelled
by a court or governmental agency, in each case provided that prior written notice is given to Company, Executive will not, without the written consent of Company, willfully disseminate or otherwise disclose, directly or indirectly, any Confidential
Information obtained during his or her employment with the Company or its Affiliates, and will take all necessary precautions to prevent disclosure, to any unauthorized individual or entity inside or outside the Company, and will not use the
Confidential Information or permit its use for the benefit of Executive or any other person or entity other than the Company or its Affiliates. These obligations shall continue during and after the termination of Executive’s employment (whether
or not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation). 
  

 37 

 8.2 Non-Competition. During the period beginning on the Agreement Date and ending on the second
anniversary of the Termination Date, whether or not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation, Executive hereby agrees that without the written consent of the Company Executive shall not at any
time, directly or indirectly, in any capacity: 
 (a) engage or participate in, become employed by, serve as a director of, or
render advisory or consulting or other services in connection with, any Competitive Business; provided, however, that after the Termination Date this Section 8.2 shall not preclude Executive from being an employee of, or consultant to, any
business unit of a Competitive Business if (i) such business unit does not qualify as a Competitive Business in its own right and (ii) Executive does not have any direct or indirect involvement in, or responsibility for, any operations of
such Competitive Business that cause it to qualify as a Competitive Business. 
 (b) make or retain any financial investment,
whether in the form of equity or debt, or own any interest, in any Competitive Business. Nothing in this subsection shall, however, restrict Executive from making an investment in any Competitive Business if such investment does not
(i) represent more than 1% of the aggregate market value of the outstanding capital stock or debt (as applicable) of such Competitive Business, (ii) give Executive any right or ability, directly or indirectly, to control or influence the
policy decisions or management of such Competitive Business, and (iii) create a conflict of interest between Executive’s duties under this Agreement and his or her interest in such investment. 
 8.3 Non-Solicitation. During the period beginning on the Agreement Date and ending on the second anniversary of any Termination Date, whether or
not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation, Executive shall not, directly or indirectly: 
 (a) other than in connection with the good-faith performance of his or her duties as an officer of the Company, cause or attempt to cause any employee or agent of the Company to terminate his or her relationship with
the Company; 
 (b) employ, engage as a consultant or adviser, or solicit the employment or engagement as a consultant or
adviser, of any employee or agent of the Company (other than by the Company or its Affiliates), or cause or attempt to cause any Person to do any of the foregoing; 
 (c) establish (or take preliminary steps to establish) a business with, or cause or attempt to cause others to establish (or take
preliminary steps to establish) a business with, any employee or agent of the Company, if such business is or will be a Competitive Business; or 
  

 38 

 (d) interfere with the relationship of the Company with, or endeavor to entice away from
the Company, any Person who or which at any time during the period commencing one year prior to the Termination Date was or is, to the Executive’s knowledge, a material customer or material supplier of, or maintained a material business
relationship with, the Company. 
 8.4 Intellectual Property. During the period of Executive’s employment with the Company and
any Affiliate, and thereafter upon the Company’s request, whether or not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation, Executive shall disclose immediately to the Company all ideas, inventions
and business plans that he or she makes, conceives, discovers or develops alone or with others during the course of his or her employment with the Company or during the one year period following Executive’s Termination Date, including any
inventions, modifications, discoveries, developments, improvements, computer programs, processes, products or procedures (whether or not protectable upon application by copyright, patent, trademark, trade secret or other proprietary rights)
(“Work Product”) that: (i) relate to the business of the Company or any customer or supplier to the Company or any of the products or services being developed, manufactured, sold or otherwise provided by the Company or that may
be used in relation therewith; or (ii) result from tasks assigned to Executive by the Company; or (iii) result from the use of the premises or personal property (whether tangible or intangible) owned, leased or contracted for by the
Company. Executive agrees that any Work Product shall be the property of the Company and, if subject to copyright, shall be considered a “work made for hire” within the meaning of the Copyright Act of 1976, as amended (the
“Act”). If and to the extent that any such Work Product is not a “work made for hire” within the meaning of the Act, Executive hereby assigns to the Company all right, title and interest in and to the Work Product, and all
copies thereof, and the copyright, patent, trademark, trade secret and all proprietary rights in the Work Product, without further consideration, free from any claim, lien for balance due or rights of retention thereto on the part of Executive.

 (a) The Company hereby notifies Executive that the preceding paragraph does not apply to any inventions for which no
equipment, supplies, facility, or trade secret information of the Company was used and which was developed entirely on the Executive’s own time, unless: (i) the invention relates (a) to the Company’s business, or (b) to the
Company’s actual or demonstrably anticipated research or development, or (ii) the invention results from any work performed by the Executive for the Company. 
 (b) Executive agrees that upon disclosure of Work Product to the Company, Executive will, during his or her employment and at any time
thereafter, at the request and cost of the Company, execute all such documents and perform all such acts as the Company or its duly authorized agents may reasonably require: (i) to apply for, obtain and vest in the name of the Company alone
(unless the Company otherwise directs) letters patent, copyrights or other analogous protection in any country throughout the world, and when so obtained or vested to renew and restore the same; and (ii) to prosecute or defend any opposition
proceedings in respect of such applications and any opposition proceedings or petitions or applications for revocation of such letters patent, copyright or other analogous protection, or otherwise in respect of the Work Product. 
  

 39 

 (c) In the event that the Company is unable, after reasonable effort, to secure
Executive’s execution as provided in subsection (b) above, whether because of Executive’s physical or mental incapacity or for any other reason whatsoever, Executive hereby irrevocably designates and appoints the Company and its duly
authorized officers and agents as his or her agent and attorney-in-fact, to act for and on his or her behalf to execute and file any such application or applications and to do all other lawfully permitted acts to further the prosecution, issuance
and protection of letters patent, copyright and other intellectual property protection with the same legal force and effect as if personally executed by Executive. 
 8.5 Reasonableness of Restrictive Covenants. 
 (a) Executive acknowledges that the
covenants contained in Sections 8.1, 8.2, 8.3 and 8.4 are reasonable in the scope of the activities restricted, the geographic area covered by the restrictions, and the duration of the restrictions, and that such covenants are reasonably necessary
to protect the Company’s legitimate interests in its Confidential Information and in its relationships with its employees, customers and suppliers. Executive further acknowledges such covenants are essential elements of this Agreement and that,
but for such covenants, the Company would not have entered into this Agreement. 
 (b) The Company and Executive have each
consulted with their respective legal counsel and have been advised concerning the reasonableness and propriety of such covenants. Executive acknowledges that Executive’s observance of the covenants contained in Sections 8.1, 8.2, 8.3 and 8.4
will not deprive Executive of the ability to earn a livelihood or to support his or her dependents. 
 8.6 Right to Injunction; Survival
of Undertakings. 
 (a) In recognition of the confidential nature of the Confidential Information, and in recognition of
the necessity of the limited restrictions imposed by Sections 8.1, 8.2, 8.3 and 8.4 the parties agree that it would be impossible to measure solely in money the damages which the Company would suffer if Executive were to breach any of his or her
obligations under such Sections. Executive acknowledges that any breach of any provision of such Sections would irreparably injure the Company. Accordingly, Executive agrees that if he or she breaches any of the provisions of such Sections, the
Company shall be entitled, in addition to any other remedies to which the Company may be entitled under this Agreement or otherwise, to an injunction to be issued by a court of competent jurisdiction, to restrain any breach, or threatened breach, of
such provisions, and Executive hereby waives any right to assert any claim or defense that the Company has an adequate remedy at law for any such breach. 
 (b) If a court determines that any of the covenants included in this Article VIII is unenforceable in whole or in part because of such covenant’s duration or geographical or other scope, such court shall have the
power to modify the duration or scope of such provision, as the case may be, so as to cause such covenant as so modified to be enforceable. 
  

 40 

 (c) All of the provisions of this Article VIII shall survive any Termination of
Employment without regard to (i) the reasons for such termination or (ii) the expiration of the Agreement Term. 
 (d) The Company shall have no further obligation to pay or provide severance or benefits under Article II, Article IV, or Article V if a court determines that the Executive has breached any covenant in this Article VIII. 
 Article IX. 
 Non-Exclusivity of
Rights 
 9.1 Other Rights. Except as expressly provided in Section 4.11 or elsewhere in this Agreement, this Agreement shall
not prevent or limit Executive’s continuing or future participation in any benefit, bonus, incentive or other Plans provided by the Company and for which Executive may qualify, nor shall this Agreement limit or otherwise affect such rights as
Executive may have under any other agreements with the Company. Amounts which are vested benefits or which Executive is otherwise entitled to receive under any Plan and any other payment or benefit required by law at or after the Termination Date
shall be payable in accordance with such Plan or applicable law except as expressly modified by this Agreement. 
 9.2 No Right to
Continued Employment. Nothing in this Agreement shall guarantee the right of Executive to continue in employment, and the Company retains the right to terminate the Executive’s employment at any time for any reason or for no reason.

 Article X. 
 Miscellaneous 
 10.1 No Assignability. This Agreement is personal to Executive and without the prior written consent
of the Company shall not be assignable by Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by Executive’s legal representatives. 
 10.2 Successors. This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns. The Company will
require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and
to the same extent that the Company would be required to perform it if no such succession had taken place. Any successor to the business or assets of the Company which assumes or agrees to perform this Agreement by operation of law, contract, or
otherwise shall be jointly and severally liable with the Company under this Agreement as if such successor were the Company. 
 10.3
Affiliates. To the extent that immediately prior to the Applicable Trigger Date, the Executive has been on the payroll of, and participated in the incentive or employee benefit plans of, an Affiliate of the Company, the references to the
Company contained in Sections 2.8(a)(i) through (vii) and the other Sections of this Agreement referring to benefits to which the Executive may be entitled shall be read to refer to such Affiliate. 
  

 41 

 10.4 Payments to Beneficiary. If Executive dies before receiving amounts to which Executive is
entitled under this Agreement, such amounts shall be paid in a lump sum to one or more beneficiaries designated in writing by Executive (each, a “Beneficiary”) within 90 days after the date of Executive’s death. If none is so
designated, the Executive’s estate shall be his or her Beneficiary. 
 10.5 Payment of Reimbursable Expenses. Any reimbursement
(including any advancement) payable to Executive pursuant to this Agreement shall be conditioned on the submission by Executive of all expense reports reasonably required by the Company under any applicable expense reimbursement policy, and shall be
paid to the Executive 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 Executive 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 Agreement shall not be subject to liquidation or
exchange for any other benefit. 
 10.6 Non-Alienation of Benefits. Benefits payable under this Agreement shall not be subject in any
manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind, either voluntary or involuntary, before actually being received by Executive, and any such attempt to dispose of
any right to benefits payable under this Agreement shall be void. 
 10.7 Severability. If any one or more Articles, Sections or other
portions of this Agreement are declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any Article, Section or other portion not so declared to be unlawful or invalid.
Any Article, Section or other portion so declared to be unlawful or invalid shall be construed so as to effectuate the terms of such Article, Section or other portion to the fullest extent possible while remaining lawful and valid. 
 10.8 Amendments This Agreement shall not be amended or modified except by written instrument executed by the Company and Executive. 
 10.9 Notices. All notices and other communications under this Agreement 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 Executive, to Executive at his or her most recent home address on file with the Company.

Company and the Subsidiary shall be jointly and severally liable for the obligations of the Company, the Subsidiary, or the Employer hereunder.

choice of law principles. 
 10.13 Captions. The captions of this Agreement are not a part of the provisions hereof and shall have no

 10.15 Tax Withholding. The Company may withhold from any amounts payable

10.16 Section 409A. This Agreement 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 Agreement would subject Executive to 409A Penalties, the Company and Executive shall cooperate diligently to amend the terms of the Agreement
to avoid such 409A Penalties, to the extent possible. The payments to Executive pursuant to Section 4 of this Agreement are intended to be exempt from Section 409A of the Code to the 

  

 43 

 
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 Executive under Section 4 shall be considered a separate payment. Notwithstanding any other provision in this
Agreement, if on the date of Executive’s Termination Date, (i) the Company is a publicly traded corporation and (ii) Executive is a “specified employee,” as defined in Section 409A of the Code, then to the extent any
amount payable under this Agreement constitutes the payment of nonqualified deferred compensation, within the meaning of Section 409A of the Code, that under the terms of this Agreement 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 Executive’s death. 
 10.17 No Waiver. Executive’s failure to insist upon strict compliance with any provision of this Agreement shall not be deemed a waiver of
such provision or any other provision of this Agreement. A waiver of any provision of this Agreement shall not be deemed a waiver of any other provision, and any waiver of any default in any such provision shall not be deemed a waiver of any later
default thereof or of any other provision. 
 10.18 Entire Agreement. This Agreement, as amended and restated effective
January 1, 2009, contains the entire understanding of Company and Executive with respect to its subject matter.
