                           SECOND AMENDED AND RESTATED
                               EXELON CORPORATION
                          KEY MANAGEMENT SEVERANCE PLAN

1. AMENDMENT AND RESTATEMENT; PURPOSE OF THE PLAN

         The Unicom Corporation Key Management Severance Plan (as amended and
restated, the "Plan") was established, effective June 15, 1998, by Unicom
Corporation ("Unicom") to provide certain key employees of Commonwealth Edison
Company ("ComEd") and other subsidiaries of Unicom (jointly and severally
referred to herein as the "Company" prior to October 20, 2000) certain severance
benefits in the event the employment of such employees terminates under the
circumstances described herein. The Plan was amended and restated, effective
March 8, 1999, to reflect a policy approved by the Board of Directors of the
Company which provides benefits in the event a key employee's employment is
terminated by the Company other than for Cause or the employee resigns for Good
Reason within 24 months following a Change in Control of the Company.

         The Plan was further amended, effective October 20, 2000 (the "Merger
Effective Date"), to reflect the merger of Unicom Corporation with PECO Energy
Company. From and after the Merger Effective Date, Exelon Corporation ("Exelon")
and any subsidiary thereof of which Exelon owns at least 50% of all of the
outstanding voting power are jointly and severally referred to herein as the
"Company".

         The Plan was further amended and restated effective June 1, 2001
("Restatement Date"), to reflect a policy approved by the Board of Directors of
Exelon which provides additional protection in the event of a new Change in
Control of Exelon or an Imminent Control Change of Exelon. The Plan, as so
amended and restated, shall apply solely to persons who satisfy the applicable
eligibility criteria in Section 2 and all the criteria for participation in
Section 3.

         This document serves as both the Plan document and the summary plan
description which is required to be provided to participants under the Employee
Retirement Income Security Act of 1974, as amended ("ERISA").

2. ELIGIBILITY

         1.1 Eligibility in General. In order to be eligible to become a
         Participant, each individual whose position is in Salary Band VII or
         above (an "Executive") must execute non-competition, non-solicitation,
         confidential information and intellectual property covenants
         ("Restrictive Covenants") which are substantially in the form attached
         hereto and made a part hereof as Exhibit I.

         1.2 Benefits Provided Under Section 4. Each Executive shall be eligible
         for the benefits provided under Section 4 hereof in the event such
         Executive has a Termination of Employment; provided, however, that any
         Executive whose Termination of Employment is covered under Section 5
         hereof or who is entitled to benefits under a change in control
         agreement entered into after October 20, 2000 between such Executive
         and the Company ("Individual Change in Control Agreement") shall not be
         entitled to benefits under
<PAGE>
         Section 4, except as expressly provided in Section 5 or such Individual
         Change in Control Agreement (which expressly refers to the benefits
         under Section 4 of this Plan), until such Executive is no longer
         eligible for benefits under Section 5 or under such Individual Change
         in Control Agreement, as applicable.

         1.3 Benefits Provided Under Section 5. Eligibility for the benefits
         provided under Section 5 hereof due to a Termination of Employment
         during the Current Post-Merger Period shall be limited to Executives
         who, (i) on the day prior to the Merger Effective Date, were on the
         payroll of a Unicom subsidiary or PECO Energy Company, and (ii) execute
         an acceptance of substitution of the benefits under the Plan as it
         existed on the day prior to the Restatement Date or of the benefits
         under an individual Change in Control Agreement between the Executive
         and PECO Energy Company entered into prior to the Merger Effective Date
         (a "PECO Agreement"), as applicable, for the benefits under the Plan as
         it exists on and after the Restatement Date (the "Acceptance of
         Substitution") in a form satisfactory to the Company. Any otherwise
         eligible Executive who is required, but declines, to execute an
         Acceptance of Substitution under Section 3 shall be covered with
         respect to a Termination of Employment occurring during the Current
         Post-Merger Period solely under the terms of Section 5 of the Plan as
         in effect immediately prior to the Restatement Date or under the terms
         of such Executive's PECO Agreement, as applicable, and shall not
         thereafter be eligible for benefits under Section 5 of the Plan in the
         event of a Change in Control or Imminent Control Change. In all events,
         benefits provided under Section 5 hereof shall be subject to the
         provisions of any agreement between an Executive and the Company that
         provided that such Executive would be ineligible for the benefits under
         Section 5 or "change in control benefits" in the event of a termination
         of employment, or under which the Executive had agreed, prior to the
         Merger Effective Date or Restatement Date, to terminate his or her
         employment.

3. PARTICIPATION

         Each eligible Executive shall become a participant in the Plan
("Participant") upon his or her execution of an agreement with the Company in
such form as the Company, in its sole discretion, shall require or permit (the
"Severance Agreement"). Each Executive shall also be required to execute, no
later than the date of the Participant's Termination of Employment or, if later,
such date indicated by the Plan Administrator which shall be no less than 45
days after the date the Executive is provided with a copy of a Severance
Agreement, a waiver and release of claims against the Company ("Waiver and
Release") which is substantially in the form attached hereto and made a part
hereof as Exhibit II. The Company shall have no obligation to Executive under
this Plan unless and until Executive executes the Restrictive Covenants, a
Severance Agreement, Acceptance of Substitution (if applicable) and a Waiver and
Release. If a court determines that Executive has breached any Restrictive
Covenant, the Company shall not be obligated to pay or provide any severance pay
or other benefits under Section 4 or 5 of this Plan, all unexercised Stock
Options shall terminate as of the date of such breach, and all Restricted Stock
shall be forfeited as of the date of such breach.

4. BENEFITS

         If a Participant is entitled to benefits under Section 5, then such
Participant shall not be eligible for benefits under this Section 4 unless so
expressly provided in Section 5. Subject to the preceding sentence, benefits
under the Plan shall be those described in this Section 4; provided, however,
that if, under the terms of an offer of employment or employment agreement with
the Company, a Participant would be entitled to additional benefits (e.g., years
of credited service and/or age under a SERP, or other special termination
provisions), the terms of such offer of employment or other agreement shall be
incorporated into any Severance Agreement hereunder, provided further, however,
that if, under the terms of any such offer of employment or employment agreement
with the Company, a Participant would be entitled to benefits which, in
aggregate, exceed the value of benefits under the Plan, the terms of such offer
of employment or other agreement shall control and no payments or benefits shall
be provided under this Plan.

         1.4 Severance Pay. Each Participant shall receive severance pay at a
         monthly rate equal to 1/12 of the sum of (a) the Participant's annual
         base salary in effect as of the date of Termination of Employment ,
         plus (b) the Severance Incentive. Payment shall be made biweekly for
         the duration of the applicable Salary Continuation Period, as indicated
         below, commencing no later than the second paydate which occurs after
         the date of the Participant's Termination of Employment, but in no
         event earlier than the date which is eight days after the date the
         Participant returns an executed Waiver and Release to the Plan
         Administrator. Payment will be made in accordance with the Company's
         normal payroll practices, net of applicable taxes and other deductions.

</TABLE>

         1.5 Annual Incentive Awards. Each Participant shall receive a Target
         Incentive which shall be prorated by multiplying the amount of such
         Target Incentive by a fraction the numerator of which is the number of
         days elapsed during such calendar year as of the date of such
         Termination of Employment and the denominator of which is 365. Payment
         of Target Incentives under this Section 4.2 shall be made in a lump sum
         net of applicable taxes and other deductions no earlier than the date
         which is eight days after the date the Participant returns an executed
         Waiver and Release to the Plan Administrator.

         1.6 Stock Options. No Participant shall be entitled to participate in
         any grants of Stock Options (as defined in Section 5.1(b)) made after
         such Participant's Termination of Employment. Except as provided below,
         any Stock Options granted to a Participant prior to such Participant's
         Termination of Employment shall be exercisable only to the extent such
         Stock Options are exercisable as of the date of such Termination of
         Employment and shall thereafter be exercised in accordance with the
         provisions of the LTIP. Stock Options which remain unexercisable as of
         the date of a Participant's Termination of Employment shall be
         forfeited. Notwithstanding the preceding, if, as of the date of a
         Participant's Termination of Employment (or, if later, the last day of
         such Participant's


                                     - 3 -
<PAGE>
         Salary Continuation Period), such Participant has attained at least age
         50 (but not age 55) and completed at least 10 years of service as
         defined under any defined benefit plan maintained by an Employer (a
         "Pension Plan") (or who, pursuant to the terms of an offer of
         employment or employment agreement or under any provision of a Pension
         Plan or SERP, is credited with a number of additional years of age
         and/or service that would enable such Participant to satisfy the above
         eligibility requirements), then any Stock Options granted to such
         Participant which have not become exercisable prior to the date of the
         Termination of Employment 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.

         1.7 Other LTIP Awards. Awards of Performance Shares and/or Restricted
         Stock (as defined in Sections 5.1(c) and 5.1(d), respectively) shall be
         payable to a Participant to the extent provided under the terms of such
         Awards.

         1.8 Health Care Coverage. During the Salary Continuation Period, a
         Participant shall continue to participate in the health care plans
         under which he or she was covered immediately prior to his or her
         Termination of Employment. The Participant's out of pocket costs
         (including premiums, deductibles and co-payments) for such coverage
         shall be the same as that in effect from time to time for active peer
         employees during such period. Coverage under this Paragraph 4.4 shall
         be provided for the duration of the Salary Continuation Period in lieu
         of continuation coverage under Section 4980B of the Code and Section
         601 to 609 of ERISA ("COBRA") for the same period. At the end of the
         Salary Continuation Period, COBRA continuation coverage may be elected
         for the remaining balance of the statutory coverage period, if any;
         provided, however that a Participant who, as of the last day of the
         Salary Continuation Period has attained at least age 50 (but not age
         55) and completed at least 10 years of service under the terms of any
         Pension Plan (or who, pursuant to the terms of an offer of employment
         or employment agreement or under any provision of a Pension Plan or
         SERP, is credited with a number of additional years of age and/or
         service that would enable such Participant to satisfy the above
         eligibility requirements) shall be entitled to elect retiree health
         coverage under the Company's health care plans on the same terms and
         subject to the same conditions as active peer employees who have
         attained age 55 and are eligible to begin receiving early retirement
         benefits under the Pension Plan.

         1.9 Retirement Plans. During the Salary Continuation Period, a
         Participant shall accrue credited service under the SERP. The amount of
         any payment made under Section 4.1 to the Participant during such
         period shall be taken into account as compensation for purposes of the
         SERP, and each Participant may also elect to participate in the Exelon
         Corporation Deferred Compensation Plan during the Salary Continuation
         Period with respect to the portion of any such payment which is
         attributable to base salary. A Participant in the Plan shall not accrue
         service or otherwise actively participate in any tax-qualified
         retirement or savings plan sponsored by the Company during the Salary
         Continuation Period, and shall not be entitled to commence to receive
         benefits under any such plan until after the expiration of the Salary
         Continuation Period.

<PAGE>
         1.10 Life Insurance and Disability Coverage. Continued coverage under
         the life insurance and long term disability plans sponsored by the
         Company shall be extended to each Participant through the last day of
         the Salary Continuation Period applicable to such Participant on the
         same terms and subject to the same conditions as are applicable to
         active peer employees.

         1.11 Deferred Compensation Plans. The elections, if any, made by an
         Executive under any non-qualified deferred compensation plan sponsored
         by the Company shall remain in effect through the last day of such
         participant's Salary Continuation Period, but such individual shall not
         be entitled to make any deferral additional elections with respect to
         such plans after December 31 of the year in which occurs the
         Participant's Termination of Employment.

         1.12 Executive Perquisites. Executive perquisites shall terminate
         effective as of the date of a Participant's Termination of Employment,
         and any Company-owned property shall be required to be returned to the
         Company no later than such date; provided, however, that each
         Participant who is an officer of the Company and who is retiring at the
         end of the Salary Continuation Period shall be entitled to financial
         counseling services for a period of 24 months following the date of
         such Participant's Termination of Employment.

                  (a) Outplacement Services. Each Participant shall be entitled
                  to outplacement services at the expense of the Company for
                  such period (which shall not be less than six months) and
                  subject to such terms and conditions as the Plan
                  Administrator, in its sole discretion, determines are
                  appropriate. No cash shall be paid in lieu of such fees and
                  costs.

5. CHANGE IN CONTROL BENEFITS

         A Participant described in Section 2.2 who is not subject to an
Individual Change in Control Agreement shall be entitled to benefits pursuant to
this Section 5 if such a Participant has a Termination of Employment during the
Current Post-Merger Period (subject to Section 2.3), Post-Change Period or
Imminent Control Change Period, and such Participant shall not be eligible for
benefits under Section 4 unless so expressly provided in this Section 5;
provided, however, that if, under the terms of an offer of employment or
employment agreement with the Company, a Participant would be entitled to
benefits which exceed the level of benefits under the Plan, the terms of such
offer of employment or other agreement shall control and no payments or benefits
shall be provided under this Plan to the extent that such payment or benefits
would reasonably be considered, by the Plan Administrator, duplicative.

         Period, an eligible Executive has a Termination of Employment and
         becomes a Participant, the Company's sole obligations under Section 4
         and Sections 5.1 and 5.2 shall be as set forth in this Section 5.1
         (subject to Section 5.3, 5.5, 5.6, 5.7 and 5.8).

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

                           (i) Accrued Obligations. All Accrued Obligations;

                           amount equal to the Target Incentive applicable to
                           such Participant under the Incentive Plan for the
                           performance period in which the Termination Date
                           occurs;

                           (iii) Deferred Compensation and Non-Qualified Defined
                           Contribution Plans. All amounts previously deferred
                           by, or accrued to the benefit of, such Participant

                           compensation plan of the Company (unless such
                           Participant has made an irrevocable election in

                                             (a) become fully vested in all
                                             benefits,

                                             benefits, entitlement to - but not

                                             accrued by such Participant as of
                                             the Termination Date and that

                                             such Participant, and

                                             (d) received the severance benefits
                                             specified in Sections 5.1(a)(ii)
                                             and 5.1(a)(vi) as covered

                           the extent not paid pursuant to clause (iii) or (iv)
                           of this Section 5.1(a), an amount equal to the
                           actuarial equivalent present value of the unvested
                           portion of such Participant's accounts or accrued
                           benefits under any tax-qualified (under Section
                           401(a) of the Code) defined benefit retirement plan
                           maintained by the Company as of the Termination Date
                           and forfeited by such Participant by reason of the
                           Termination of Employment; and

                           (vi) Multiple of Salary and Severance Incentive. An
                           amount equal to two (2) times the sum of (x) Base

                  (b) Stock Options. Each of such Participant'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.

                  (c) LTIP Vesting. On the Termination Date, all of the
                  performance shares, performance units or similar stock
                  incentive awards granted to such Participant under the Exelon
                  Performance Share Program under the LTIP ("Performance

                  shall become fully vested at the LTIP Target Level.

                  (d) Other Restricted Stock. All forfeiture conditions that as
                  of the Termination Date are applicable to any deferred stock
                  unit, restricted stock or restricted share units awarded to
                  such Participant by Exelon other than under the Exelon
                  Performance Share Program under the LTIP ("Restricted Stock")
                  shall lapse immediately and all such awards will become fully
                  vested, and within ten business days after the Termination
                  Date, Exelon shall deliver or cause to be delivered to such
                  Participant all of such shares theretofore held by or on
                  behalf of Exelon.

                  (e) Continuation of Welfare Benefits. During the Severance
                  Period and continuing through such later date as may be
                  specified in any welfare plan of the Company (including
                  medical, prescription, dental, disability, employee life,
                  group life, accidental death, and travel accident insurance
                  benefits but excluding any severance pay) ("Welfare Plan")
                  that covered the Participant or such Participant's family
                  prior to such Participant's Termination of Employment, the
                  Company shall continue to provide (or shall cause the
                  continued provision) to such Participant and such
                  Participant's family welfare benefits under the Welfare Plans
                  to the same extent as if such Participant 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, such Participant's annual compensation
                           attributable to base salary and incentives for any
                           plan year or calendar year, as applicable, shall be
                           deemed to be not less than such Participant's Base
                           Salary and annual incentive.

                           (ii) The cost of such welfare benefits to such
                           Participant and family under this Section 5.1(e)
                           shall not exceed the cost of such benefits to peer
                           executives who are actively employed after the
                           Termination Date.

                           (iii) Such Participant's rights under this Section
                           5.1(e) shall be in addition to and not in lieu of any
                           post-termination continuation coverage or conversion
                           rights such Participant may have pursuant to
                           applicable law, including, without limitation,
                           continuation coverage required by COBRA.

                           (iv) If such Participant has, as of the last day of
                           the Severance Period, attained age 50 and completed
                           at least 10 years of service with the Company (five
                           years with respect to any Termination of Employment
                           occurring during the Current Post-Merger Period),
                           such Participant shall be entitled to the retiree
                           benefits provided under any Welfare Plan of the
                           Company; provided, however, that for purposes hereof,
                           any years of age and/or credited service granted to
                           such Participant in any other plan or agreement
                           between such Participant and the Company shall be
                           taken into account. For purposes of determining
                           eligibility for (but not the time of commencement of)
                           such retiree benefits, such Participant shall also be
                           considered (1) to have remained employed until the
                           last day of the Severance Period and to have retired
                           on the last day of such period, and


                                     - 8 -
<PAGE>
                           (2) to have attained at least the age such
                           Participant would have attained on the last day of
                           the Severance Period.

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

                  (f) Outplacement. To the extent actually incurred by such
                  Participant, the Company shall pay or cause to be paid on
                  behalf of such Participant, as incurred, all reasonable fees
                  and costs charged by a nationally recognized outplacement firm
                  selected by such Participant for outplacement services
                  provided for up to 12 months after the Termination Date. No
                  cash shall be paid in lieu of such fees and costs.

                  (g) Indemnification. Such Participant 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
                  Restatement Date if such Participant was, is, or is threatened
                  to be, made a party to any pending, completed or threatened
                  action, suit, arbitration, alternate dispute resolution
                  mechanism, investigation, administrative hearing or any other
                  proceeding whether civil, criminal, administrative or
                  investigative, and whether formal or informal, by reason of
                  the fact that such Participant is or was, or had agreed to
                  become, a director, officer, employee, agent, or fiduciary of
                  the Company any other entity which such Participant is or was
                  serving at the request of the Company ("Proceeding"), against
                  all expenses (including all reasonable attorneys' fees) and
                  all claims, damages, liabilities and losses incurred or
                  suffered by such Participant or to which such Participant may
                  become subject for any reason. Upon receipt from such
                  Participant of (i) a written request for an advancement of
                  expenses, which such Participant reasonably believes will be
                  subject to indemnification hereunder and (ii) a written
                  undertaking by such Participant to repay any such amounts if
                  it shall ultimately be determined that such Participant is not
                  entitled to indemnification under this Plan or otherwise, the
                  Company shall advance such expenses to such Participant or pay
                  such expenses for such Participant, all in advance of the
                  final disposition of any such matter.

                  (h) 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 such Participant with coverage under a
                  directors' and officers' liability insurance policy in an
                  amount no less than, and on terms no less favorable than,
                  those provided to senior executive officers and directors of
                  the Company on the Applicable Trigger Date.

         1.14 Termination During an Imminent Control Change Period. If, during
         an Imminent Control Change Period, a Participant has a Termination of
         Employment, then, unless such Termination of Employment occurred during
         the Current Post-Merger Period, such Participant shall receive benefits
         as provided in Section 4 and the Company's sole obligations to such
         Participant under Sections 5.1 and 5.2 shall be as set forth in this
         Section 5.2 (and subject to Sections 5.3, 5.5, 5.6, 5.7 and 5.8). The
         Company's obligations to such Participant under this Section 5.2 shall
         be reduced by any amounts or benefits paid or provided pursuant to
         Section 4. If such Participant's Termination of Employment occurred
         during any portion of an Imminent Control Change Period that is also
         the Current Post-Merger Period, the Company's obligations to such
         Participant, if any, shall be determined under Section 5.1.

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

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

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

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

                  If the Imminent Control Change Period lapses without a Change
                  Date, then such Participant's Stock Options, to the extent
                  vested on the Termination Date, may be exercised, in whole or
                  in part, during the 30-day period following the lapse of the
                  Imminent Control Change, or, if larger, the period during
                  which such Participant's vested Stock Options could otherwise
                  be exercised under the terms of the applicable grant agreement
                  or the LTIP (but in no case shall any Stock Options remain
                  exercisable after the date on which such Stock Options would
                  have expired if such Participant had remained an employee of
                  the Company).

                  If the Imminent Control Change Period culminates in a Change
                  Date, then effective upon the Change Date, such Participant's
                  Stock Options, to the extent vested on the Termination Date,
                  may be exercised in whole or in part by such Participant at
                  any time until (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


                                     - 10 -
<PAGE>
                  Change Date or the option expiration date for such Stock
                  Options granted on or after January 1, 2002.

                  (c) Unvested Stock Options. Such Participant's Stock Options
                  that are not vested on the Termination Date

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

                           (ii) will not continue to vest and will not be
                           exercisable during the Imminent Control Change Period
                           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 such Participant 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) Performance Shares. Such Participant'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. If the Imminent
                  Control Change Period culminates in a Change Date:

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

                                    (2) All of the Performance Shares granted to
                                    such Participant under the Exelon
                                    Performance Share Program under the LTIP
                                    which, as of the Termination Date, have not
                                    been earned by and awarded to such
                                    Participant shall become fully vested on the
                                    Change Date at the LTIP Target Level.

                  (e) Restricted Stock. Such Participant's unvested Restricted
                  Stock will:

<PAGE>
                           (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, such
                  Participant's Restricted Stock shall become fully vested, and
                  within ten business days after the Change Date, the Company
                  shall deliver to such Participant all of such shares
                  theretofore held by or on behalf of the Company, which will be
                  subject to the same terms which other stockholders of the
                  Company receive in the transaction.

                  (f) Continuation of Welfare Benefits. The Company shall
                  continue to provide (or cause to be provided) to such
                  Participant and such Participant's family welfare benefits
                  (other than any severance pay that may be considered a welfare
                  benefit) that covered the Participant or such Participant's
                  family prior to such Participant's Termination of Employment,
                  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 by the Company after the
                  Termination Date and their families; subject to the following:

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

                           (ii) the cost of such welfare benefits to such
                           Participant and family under this Section 5.2(f)
                           shall not exceed the cost of such benefits to peer
                           executives who are actively employed by the Company
                           after the Termination Date; and

                           (iii) such Participant's rights under this Section
                           5.2(f) shall be in addition to and not in lieu of any
                           post-termination continuation coverage or conversion
                           rights such Participant may have pursuant to
                           applicable law, including, without limitation,
                           continuation coverage required by COBRA.

                  If the Imminent Control Change Period lapses without a Change
                  Date, welfare benefit plan coverage under this Section 5.2(f)
                  shall thereupon cease, subject to such Participant's rights,
                  if any, to continued coverage under a Welfare Plan, Section 4,
                  or applicable law. If the Imminent Control Change Period
                  culminates in a Change Date, then for the remainder of the
                  Severance Period (and continuing through such later date as
                  any Welfare Plan may specify), the Company shall continue to
                  provide such Participant and such Participant's family welfare
                  benefits as described in, and subject to the limitations of
                  Section 5.1(e).


                                     - 12 -

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

                  (g) Outplacement. To the extent actually incurred by such
                  Participant, the Company shall pay or cause to be paid on
                  behalf of such Participant, as incurred, all reasonable fees
                  and costs charged by a nationally recognized outplacement firm
                  selected by such Participant for outplacement services
                  provided for up to 12 months after the Termination Date. No
                  cash shall be paid in lieu of such fees and costs.

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

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

         5.3 Timing of Severance Payments. Unless otherwise specified herein,
         the amounts described in Sections 5.1(a)(i), (ii), (iii), (iv) and (v)
         shall be paid within 30 business days of the Termination Date. The
         severance payments described in Section 5.1(a)(vi) shall be paid
         beginning no later than the second paydate which occurs after the
         Termination Date, in periodic payments to a Participant according to
         the Company's normal payroll practices at a monthly rate equal to 1/12
         of the sum of (i) such Participant's Base Salary in effect as of the
         Termination Date plus (ii) the Severance Incentive.

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

                  (a) Obligations. If, during the Current Post-Merger Period,
                  the Post-Change Period, or the Imminent Control Change Period,
                  (i) the Company terminates an eligible Executive's employment
                  for Cause (or causes a Participant to be terminated for Cause)
                  ("Cause Termination") or disability (as determined by the Plan
                  Administrator in good faith), (ii) an Executive elects to
                  retire or otherwise terminate employment other than for Good
                  Reason, disability or death, or (iii) an eligible Executive's
                  employment terminates on account of death or disability, the
                  Company shall have no obligations to such Executive under
                  Section 5 (subject to Section 5.7). The remaining applicable
                  provisions of this Plan (including the Restrictive Covenants)
                  shall continue to apply.

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

         5.5 Sole and Exclusive Obligations. The obligations of the Company
         under this Plan with respect to any Termination of Employment occurring
         during the Current Post-Merger Period, Post-Change Period, or Imminent
         Control Change Period shall supersede any severance obligations of the
         Company in any other plan of the Company or agreement between such
         Participant and the Company, including, without limitations, Section 4,
         any Individual Change in Control Agreement affecting such Participant
         or any other plan or agreement (including an offer of employment or
         employment contract) of the Company which provides for severance
         benefits, except as explicitly provided in Section 5.2 or an Individual
         Change in Control Agreement. In the event of any inconsistency,
         ambiguity or conflict between the terms of such other plan of the
         Company or agreement between a Participant and the Company, and this
         Plan with respect to any severance obligations of the Company (other
         than obligations with respect to age and/or credited service under the
         SERP in any agreement other than a prior Individual Change in Control
         Agreement), this Plan shall govern.

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

         5.7 Arbitration. Any dispute, controversy or claim between the parties
         hereto arising out of or in connection with or relating to this Section
         5 (other than disputes related to an alleged breach of the Restrictive
         Covenants) 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. Any party may invoke the right to
         arbitration. The arbitrator shall be selected by means


                                     - 14 -
<PAGE>
         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 Section,
         consistent with Section 12.7 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. 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 5.7
         or elsewhere in this Plan, any 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 Plan. Notwithstanding anything to the contrary
         contained in this Section 5.7 or elsewhere in this Plan, any party may
         seek relief in the form of specific performance, injunctive or other
         equitable relief in order to enforce the decision of the arbitrator.
         The parties agree that in any arbitration commenced pursuant to this
         Plan, 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.

         5.8 No Adverse Effect on Pooling of Interests. Any benefits provided to
         a Participant under this Plan may be reduced or eliminated to the
         extent necessary, in the reasonable judgment of the Board, to enable
         Exelon to account for a merger, consolidation or similar transaction as
         a pooling of interests; provided that (i) the Board shall have
         exercised such judgment and given such Participant written notice
         thereof prior to the Change Date and (ii) the determination of the
         Board shall be supported by a written certificate of Exelon's
         independent auditors, a copy of which shall be provided to such
         Participant before the Change Date.

6. TERMINATION OF PARTICIPATION; CESSATION OF BENEFITS

         A Participant's benefits under Section 4 of the Plan shall terminate on
the last day of the Participant's Salary Continuation Period; provided that a
Participant's right to benefits shall terminate immediately on such date as the
Company discovers that the Participant has breached any of the Restrictive
Covenants, in which case the Company may require the repayment of amounts paid
prior to such breach in accordance with Paragraph 4.1, and shall discontinue the
payment of any additional amounts under Section 4 of the Plan.

         A Participant's benefits under Section 5 of the Plan shall terminate on
the later of the last day of the Participant's Severance Period or the date all
benefits to which the Participant is entitled to have been paid from the Plan;
provided that a Participant's right to benefits shall terminate immediately on
the date the Company discovers that the Participant has breached any


                                     - 15 -
<PAGE>
of the Restrictive Covenants, in which case the Company may require the
repayment of amounts paid prior to such breach in accordance with Section 5, and
shall discontinue the payment of any additional amounts under Section 5 of the
Plan.

                  (e) Notice by a Participant. In the event of any Termination
                  of Employment by an eligible Executive for Good Reason, such

                  Company of the events constituting such Good Reason by a

set aside any of its assets for the purpose of funding its obligations under the
Plan. No person entitled to benefits under the Plan shall have any right, title
or claim in or to any specific assets of the Company, but shall have the right
only as a general creditor to receive benefits from the Company on the terms and
conditions provided in the Plan.

9. ADMINISTRATION OF THE PLAN

         Exelon Corporation is the "administrator" and a "named fiduciary" of
the Plan for purposes of the Employee Retirement Income Security Act of 1974, as
amended (ERISA). The Plan shall be administered on a day-to-day basis by the
Compensation Vice President of Exelon (the "Plan Administrator"). The Plan
Administrator has the sole and absolute power and authority to interpret and
apply the provisions of this Plan to a particular circumstance, make all factual
and legal determinations, construe uncertain or disputed terms and make
eligibility and benefit determinations in such manner and to such extent as the
Plan Administrator, in his or her sole discretion may determine. Benefits under
the Plan will be paid only if the Plan Administrator, in his or her discretion,
determines that an individual is entitled to them.

         The Plan Administrator shall promulgate any rules and regulations
necessary to carry out the purposes of the Plan or to interpret the terms and
conditions of the Plan; provided, however, that no rule, regulation or
interpretation shall be contrary to the provisions of the Plan. The rules,
regulations and interpretations made by the Plan Administrator shall be applied
on a uniform basis and shall be final and binding on any Executive or former
Executive and any successor in interest.

         The Plan Administrator may delegate any administrative duties,
including, without limitation, duties with respect to the processing, review,
investigation, approval and payment of severance pay and provision of severance
benefits, to designated individuals or committees.

10. CLAIMS PROCEDURE

         The Plan Administrator shall determine the status of an individual as
an Executive and the eligibility and rights of any Executive or former Executive
as a Participant to any severance pay or benefits hereunder. Any Executive or
former Executive who believes that he or she is entitled to receive severance
pay or benefits under the Plan, including severance pay or benefits other than
those initially determined by the Plan Administrator, may file a claim in
writing with the Plan Administrator. No later than 90 days after the receipt of
the claim the Plan Administrator shall either allow or deny the claim in
writing.

         A denial of a claim, in whole or in part, shall be written in a manner
calculated to be understood by the claimant and shall include the specific
reason or reasons for the denial; specific reference to pertinent Plan
provisions on which the denial is based; a description of any additional
material or information necessary for the claimant to perfect the claim and an
explanation of why such material or information is necessary; and an explanation
of the claims review procedure.

         A claimant whose claim is denied (or his or her duly authorized
representative) may, within 60 days after receipt of the denial of his or her
claim, request a review upon written application to an officer designated by
Exelon and specified in the claim denial; review pertinent documents; and submit
issues and comments in writing.

         The designated officer shall notify the claimant of his or her decision
on review within 60 days after receipt of a request for review unless special
circumstances require an extension of time for processing, in which case a
decision shall be rendered as soon as possible, but not later than 120 days
after receipt of a request for review. Notice of the decision on review shall be
in writing. The officer's decision on review shall be final and binding on any
claimant or any successor in interest.

11. AMENDMENT OR TERMINATION OF PLAN

         Exelon's Chief Human Resources Officer or another designated officer of
the Company may amend, modify or terminate the Plan at any time by written
instrument; provided, however, that no amendment, modification or termination
shall deprive any Participant of any payment or benefit that the Plan
Administrator previously has determined is payable under the Plan.
Notwithstanding the foregoing, no amendment or termination that materially
adversely affects any Participant's benefits under Section 5 shall become
effective as to such Participant during: (a) the Current Post-Merger Period, (b)
the 24-month period following the Change Date or (c) during the Imminent Control
Change Period (unless such Participant consents to such termination or
amendment). Any purported Plan termination or amendment in violation of this
Section 11 shall be void and of no effect.

12. MISCELLANEOUS

         1.58 Limitation on Rights. Participation in the Plan is limited to the
         individuals described in Sections 2 and 3, and the Plan shall not apply
         to any voluntary or involuntary termination of employment that is not a
         Termination of Employment occurring on or after the Restatement Date of
         the Plan.


                                     - 26 -
<PAGE>
         1.59 No Set-off by Company. A Participant's right to receive when due
         the payments and other benefits provided for under this Plan is
         absolute, unconditional and subject to no setoff, counterclaim or legal
         or equitable defense. Time is of the essence in the performance by the
         Company of its obligations under this Plan. Any claim which the Company
         may have against a Participant, whether for a breach of this Plan, the
         Severance Agreement, or otherwise, shall be brought in a separate
         action or proceeding and not as part of any action or proceeding
         brought by such Participant to enforce any rights against the Company
         under this Plan.

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

         1.61 Affiliates. To the extent that immediately prior to the Applicable
         Trigger Date, a Participant has been on the payroll of, and
         participated in the incentive or employee benefit plans of, an
         Affiliate of Exelon (as defined in Section 7.32), the references to the
         Company or Exelon contained in applicable Sections of this Plan
         referring to benefits to which a Participant may be entitled shall be
         read to refer to such Affiliate.

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

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

         1.64 Governing Law. The Plan shall be construed and enforced in
         accordance with ERISA and the laws of the Commonwealth of Pennsylvania
         to the extent such laws are not preempted by ERISA.

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

         1.66 Successors and Assigns. This Plan shall be binding upon and inure
         to the benefit of Exelon Corporation and its successors and assigns and
         shall be binding upon and inure to the benefit of a Participant and his
         or her legal representatives, heirs and assigns. Before or upon the
         consummation of any Change in Control, Exelon shall obtain from each
         individual, entity or group that becomes a successor of Exelon by
         reason of the Change in Control, the unconditional written agreement of
         such individual, entity or


                                     - 27 -
<PAGE>
         group to assume this Plan and to perform all of the obligations of the
         Company under the Plan. Any successor to the business or assets of
         Exelon which assumes or agrees to perform this Plan by operation of
         law, contract, or otherwise shall be jointly and severally liable with
         Exelon under this Plan as if such successor were Exelon.

         No rights, obligations or liabilities of a Participant hereunder shall
be assignable without the prior written consent of Exelon Corporation. In the
event of the death of a Participant prior to receipt of severance pay or
benefits to which he or she is entitled hereunder (and, with respect to benefits
under Section 4 or Section 5, after he or she has signed the Waiver and
Release), the severance pay described in Sections 4.1, 5.1, or 5.2, as
applicable, shall be paid to his or her estate, and the Participant's dependents
who are covered under any health care plans maintained by the Company shall be
entitled to continued rights under Section 4.4 or Section 5.1(e) or Section
5.2(f), as applicable; provided that the estate or other successor of the
Participant has not revoked such Waiver and Release.

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

                           If to a Participant, to such Participant at his most

14. ERISA RIGHTS

         As a Participant in the Plan, you are entitled to certain rights and
protections under ERISA. ERISA provides that all plan participants shall be
entitled to:

         Examine, without charge, at the Plan Administrator's office at 10 S.
         Dearborn Street, Chicago, Illinois all Plan documents and copies of all
         documents filed by the Plan with the U.S. Department of Labor; and

         Obtain copies of all Plan documents and other Plan information upon
         written request to the Plan Administrator. The Plan Administrator may
         make a reasonable charge for the copies.

         In addition to creating rights for Participants, ERISA imposes duties
upon the people who are responsible for the operation of the Plan. The people
who operate the Plan, called "fiduciaries" of the Plan, have a duty to act
prudently and in the interest of you and other Participant and beneficiaries. No
one, including your employer, your union, or any other person, may fire you or
otherwise discriminate against you in any way to prevent you from obtaining your
interest in the Plan or from exercising your rights under ERISA. If your claim
for a benefit from the Plan is denied in whole or in part, you must receive a
written explanation of the reason for the denial. You have the right to have
your claim reviewed and reconsidered. Under ERISA, there are steps you can take
to enforce the above rights. For instance, if you request materials from the
Plan and do not receive them within 30 days, you may file suit in a federal
court. In such a case, the court may require the Plan Administrator to provide
the materials and pay you up to $110 a day until you receive the materials,
unless the materials were not sent because of reasons beyond the control of the
Plan Administrator. If you have a claim for benefits which is denied or ignored,
in whole or in part, you may file suit in a state or federal court. If it should
happen that Plan fiduciaries misuse the Plan's money, or if you are
discriminated against for asserting your rights, you may seek assistance from
the U.S. Department of Labor, or you may file suit in a federal court. The court
will decide who should pay court costs and legal fees. If you are successful,
the court may order the person you have sued to pay these costs and fees. If


                                     - 29 -
<PAGE>
you lose and the court finds your claim to be frivolous, the court may order you
to pay these costs and fees. If you have any questions about the Plan, you
should contact the Plan Administrator. If you have any questions about this
statement or about your rights under ERISA, you should contact the nearest Area
Office of the U.S. Labor-Management Services Administration, Department of
Labor.

CONFIDENTIAL INFORMATION.

                  (a) Obligation to Keep Confidential Information Confidential.
                  You acknowledge that in the course of performing services for
                  Exelon and its affiliates (together, the "Company"), you may
                  create (alone or with others), learn of, have access to and
                  receive Confidential Information. Confidential Information (as
                  defined below) shall not include: (i) information that is or
                  becomes generally known through no fault of yours; (ii)

                  obligation; or (iii) information approved for release by
                  written authorization of the Company. You recognize that all
                  such Confidential Information is the sole and exclusive
                  property of the Company or of third parties which the Company
                  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. You agree that, except as required by
                  your duties of employment with the Company or any of its
                  affiliates, and except in connection with enforcing your
                  rights under the Severance Plan or if compelled by a court or
                  governmental agency, in each case provided that prior written
                  notice is given to Exelon, you will not, without the written
                  consent of Exelon, willfully disseminate or otherwise
                  disclose, directly or indirectly, any Confidential Information
                  obtained during your employment with the Company, 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 your personal benefit or any other person or
                  entity other than the Company. These obligations shall
                  continue during and after the termination of your employment
                  (whether or not after a Change in Control or Imminent Control
                  Change, as such terms are defined in the Severance Plan).

                  (b) Definition of Confidential Information. "Confidential
                  Information" shall mean any information, ideas, processes,
                  methods, designs, devices, inventions, data, techniques,
                  models and other information developed or used by the Company
                  and not generally known in the relevant trade or industry
                  relating to the Company's products, services, businesses,
                  operations, employees, customers or suppliers, whether in
                  tangible or intangible form, which gives the Company a
                  competitive advantage in the harnessing, production,
                  transmission, distribution, marketing or sale of energy or the
                  transmission or distribution thereof through wire or cable or

                           (ii) information relating to existing or contemplated

                           Commonwealth of Pennsylvania, or to any comparable
                           protection afforded by applicable law; or

                           (v) any other confidential information which either
                           the Company or any customer or supplier of the
                           Company may reasonably have the right to protect by
                           patent, copyright or by keeping it secret and
                           confidential.

15.      NON-COMPETITION. DURING THE PERIOD BEGINNING ON THE DATE OF EXECUTION
         OF THIS AGREEMENT AND ENDING ON THE SECOND ANNIVERSARY OF THE

         YOU HEREBY AGREE THAT WITHOUT THE WRITTEN CONSENT OF EXELON YOU SHALL
         NOT AT ANY TIME, DIRECTLY OR INDIRECTLY, IN ANY CAPACITY:

                  (c) engage or participate in, become employed by, serve as a

                  Termination Date this Section 2 shall not preclude you 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)
                  you do 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.

                  (d) 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 you 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 you 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 your employment duties and your
                  interest in such investment.

                  (e) Definition of Competitive Business. "Competitive Business"
                  means, as of any date, any utility business and any individual
                  or entity (and any branch, office, or operation thereof) which
                  engages in, or proposes to engage in (with your assistance)
                  (i) the harnessing, production, transmission, distribution,
                  marketing or sale of energy or the transmission or
                  distribution thereof through wire or cable or similar medium,
                  (ii) any other business engaged in by the Company prior to
                  your Termination Date which represents for any calendar year
                  or is projected by the Company (as reflected in a business
                  plan adopted by any Company before your Termination Date) to
                  yield during any year during the first three-fiscal year
                  period commencing on or after your Termination Date, more than
                  5% of the gross revenue of any individual Company, and, in
                  either case, which is located (x) anywhere in the United
                  States, or (y) anywhere outside of the United States where
                  Company is then engaged in, or proposes as of the Termination
                  Date to engage in, to your knowledge, any of such activities.

16.      NON-SOLICITATION. DURING THE PERIOD BEGINNING ON THE DATE OF EXECUTION
         OF THIS AGREEMENT AND ENDING ON THE SECOND ANNIVERSARY OF ANY
         TERMINATION DATE, WHETHER OR NOT AFTER A CHANGE IN CONTROL OR IMMINENT
         CONTROL CHANGE, YOU SHALL NOT, DIRECTLY OR INDIRECTLY:

                  employee or agent of the Company (other than by the Company),
                  or cause or attempt to cause any Person to do any of the
                  foregoing;

                  which at any time during the period commencing one year prior
                  to the Termination Date was or is, to your knowledge, a
                  material customer or material supplier of, or maintained a
                  material business relationship with, the Company.

17.      INTELLECTUAL PROPERTY. DURING THE PERIOD OF YOUR EMPLOYMENT WITH THE
         COMPANY, AND THEREAFTER UPON THE COMPANY'S REQUEST, WHETHER OR NOT
         AFTER A CHANGE IN CONTROL OR IMMINENT CONTROL CHANGE, YOU SHALL

         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

         PERSONAL PROPERTY (WHETHER TANGIBLE OR INTANGIBLE) OWNED, LEASED OR

         ACT, YOU HEREBY ASSIGN TO THE COMPANY ALL RIGHT, TITLE AND INTEREST IN

                  the Company was used and which was developed entirely on your
                  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

                  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

                  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

                  revocation of such letters patent, copyright or other
                  analogous protection, or otherwise in respect of the Work
                  Product.

                  (l) In the event that the Company is unable, after reasonable
                  effort, to secure your execution as provided in subsection (b)
                  above, whether because of your physical or mental incapacity
                  or for any other reason whatsoever, you hereby irrevocably
                  designate and appoint the Company and its duly authorized
                  officers and agents as your agent and attorney-in-fact, to act
                  for and on your 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 you.

                  (m) You acknowledge that the covenants contained in Sections
                  2, 3, and 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.

                  (n) The Company and you have all consulted with their
                  respective legal counsel and have been advised concerning the
                  reasonableness and propriety of such covenants. You
                  acknowledge that your observance of the covenants contained in
                  Sections 2, 3, and 4 will not deprive you of the ability to
                  earn a livelihood or to support your dependents.

                  (o) All of the provisions of this Restrictive Covenant shall
                  survive any termination of employment without regard to (i)
                  the reasons for such termination or (ii) the expiration of any
                  participation in the Severance Plan.

                  (p) The Company shall have no further obligation to pay or
                  provide severance or benefits under the Plan if a court
                  determines that you have breached any covenant in this
                  Restrictive Covenant.

19.      COUNTERPARTS. THIS AGREEMENT MAY BE EXECUTED IN SEVERAL COUNTERPARTS,
         EACH OF WHICH SHALL BE DEEMED TO BE AN ORIGINAL, BUT ALL OF WHICH
         TOGETHER WILL CONSTITUTE ONE AND THE SAME INSTRUMENT.
