EXELON CORPORATION

CHANGE-IN-CONTROL EMPLOYMENT AGREEMENT



THIS AGREEMENT, dated as of June 1, 2001 (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
Pennsylvania corporation (together with successors thereto, the Subsidiary), and _________________ (Executive). The Agreement has been amended and restated as of May 1, 2004.



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.

As used in this Agreement, the terms specified below shall have the following
meanings:



1.1 Accrued Annual Incentive
means the amount of any Annual Incentive earned but not yet paid with respect to the Companys latest fiscal year ended prior to the Termination Date.



1.2 Accrued Base Salary means the amount of Executives Base Salary that is accrued but not yet paid as of the Termination Date.



1.3 Accrued LTIP Award means the amount of
any LTIP Award earned and vested, but either deferred or not yet paid as of the Termination Date.



1.4 Accrued Obligations means, as of any date, the sum of Executives Accrued Base Salary, Accrued Annual Incentive, Accrued LTIP
Award, 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).



1.5 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 to any Person means the power to direct or cause the





---

direction of management or policies of such Person, directly or indirectly, whether through the ownership of Voting Securities, by contract or otherwise.



1.6 Agreement Date  see the
introductory paragraph of this Agreement.



1.7
Agreement Term means the period commencing on the Agreement Date and ending on the second anniversary of the Agreement Date or, if later, such later date to which the Agreement Term is extended under the following sentence, unless
earlier terminated as provided herein. Commencing on the first anniversary of the Agreement Date, the Agreement Term shall automatically be extended each day by one day to create a new two-year term until, at any time after the first anniversary of
the Agreement Date, the Company delivers written notice (an Expiration Notice) to Executive that 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.

(a) the Change Date with respect to the Post-Change Period;



(b) the date of an Imminent Control Change with respect to the Imminent Control Change Period;



(c) the date of a Significant Acquisition with respect to
a Post-Significant Acquisition Period; and



(d) the date of a Disaggregation with respect to a Post-Disaggregation Period.

Executives unextinguished Restricted Stock, whether or not converted to restricted



15

stock of the Disaggregated Entity or Merger Survivor, will continue to vest during the Post-Disaggregation Period, subject to Section 4.3(d).



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 her legal representative, as applicable, (i) written notice in accordance with Section 10.8 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;



16



---

(iii) the Executives commission of a felony or any crime involving dishonesty or
moral turpitude;



(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.



17



---

(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 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 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



18



---

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).



(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 retains substantially the same position with the Disaggregated Entity as immediately prior to the Disaggregation (determined without regard to reporting
requirements), then (1) Section 3.4(a)(ii) shall apply only with respect to the Executives position, duties or responsibilities as in effect at the Disaggregated Entity on the day following the Disaggregation, (2) subsection 3.4(a)(iv) shall
apply only with respect to relocations required more than 60 days after the Disaggregation 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 180 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.

constructive receipt of such amounts), and in any event at least 90 days prior to the Termination Date to have such amounts paid under the terms of the Exelon Corporation Deferred Compensation Plan or the Exelon Corporation Deferred Stock Plan, as
applicable, or any successor of either (including any elections in effect thereunder)) whether vested or unvested, together with any accrued earnings thereon, to the extent that such amounts and earnings have not been previously paid by the Employer
and are not provided under the terms of either such non-qualified plan;

days after the Termination Date, the Company shall deliver to Executive all of such shares theretofore held by or on behalf of the Company.



(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.



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,



22



---

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. 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 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



23



---

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 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, a lump-sum cash amount, within thirty business days after the later of the Termination Date or
the Change Date, equal to the sum of all amounts described in Section 4.1(a)(i) through (v). The amount described in Section 4.1(a)(vi) 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



24



---

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).



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.



(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.



(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



(2) All of the Performance
Shares granted to the Executive under the Exelon Performance Share Program under the LTIP which, as of



25



---

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, and within ten
business days after the Change Date, the Company shall deliver to Executive all of such shares theretofore held by or on behalf of the Company, which will be subject to the same terms which other stockholders of the Company receive in the
transaction.



(f) 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 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



26



---

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.

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.

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 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



27



---

Date or the option expiration date for such Stock Options granted on or after January 1, 2002.



(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 provided up to 12 months
after the Termination Date. No cash shall be paid in lieu of such fees and costs.



(g) Termination During a Post-Disaggregation Period: Indemnification. The Executive shall be indemnified and held harmless by the
Company to the same extent as provided in Section 4.1(g).



(h) Termination During a Post-Disaggregation Period: Directors and Officers Liability Insurance. The Company shall provide Executive with directors and officers liability insurance to
the same extent as provided in Section 4.1(h).



4.4 Timing
of Severance Payments. Unless otherwise specified herein, the amounts described in Sections 4.1(a)(i), (ii), (iii), (iv) and (v) shall be paid within 30 business days of the Termination 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, the Company shall make periodic payments to the Executive



28



---

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).



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.



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), (ii) and (iii) determined as
of the Termination Date, and



29



---

(b) 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.



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, 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 her death.



4.11 Sole and Exclusive Obligations. The obligations of the Company under this Agreement, as amended and restated effective May 1, 2004,
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



30



---

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



(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 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



31



---

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, 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,



32



---

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).



(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.



33



---

(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.



(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).



34

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.



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 10.11 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



35



---

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 employment the Executive engaged in
conduct described in Section 3.3(a)(iii) or the last clause of Section 3.3(a)(iv). 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, 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 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).



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



37



---

| | 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 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 her duties as an officer of the Company, cause or attempt to cause any
employee or agent of the Company to terminate 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



(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 she makes, conceives, discovers or develops alone or with others during the course of 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



38



---

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 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.



(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 her agent and attorney-in-fact, to act for and on 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



39



---

covenants. Executive acknowledges that her 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 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 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 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.



(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

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.



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). If none is so designated, the Executives estate shall be her Beneficiary.



10.5 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.



10.6 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.
