Kingsley, Jr. ("Executive"), a resident of Illinois, amends and restates, to be effective immediately upon the Agreement Date, that certain Employment Agreement dated as of November 1, 1997, as amended, between ComEd and Executive.

WHEREAS, Executive is currently serving as Senior Executive Vice President of the Company and President and Chief Executive Officer of Genco;

WHEREAS, Commonwealth Edison Company ("ComEd") was a subsidiary of Unicom Corporation;

WHEREAS, effective October 20, 2000 Unicom Corporation merged with and into the Company, which has succeeded to the rights and obligations of ComEd hereunder, except with respect to the Enhanced SERP (as defined below in Article

WHEREAS, 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 Executive, despite the possibility or occurrence of a Change in Control of the Company and the Board believes it is imperative to reduce the distraction of Executive that would result from the personal uncertainties caused by a pending or threatened Change in Control or a Significant Acquisition, to encourage Executive's full attention and dedication to the Company, and to provide Executive with compensation and benefits arrangements upon a Change in Control which are competitive with those of similarly-situated corporations;

WHEREAS, the Board has determined that Change in Control protection for Executive as incorporated into this Agreement should also include non-competition, confidential information, non-solicitation, intellectual property and non-disparagement restrictive covenants as provided in Article XII below (the "Restrictive Covenants");

WHEREAS, in order to induce Executive to enter into this Agreement, including but not limited to the Restrictive Covenants and Change in Control protection superseding the Prior CIC Agreement, and to induce Executive to continue to serve as Senior Executive Vice President of the Company and President and Chief Executive Officer of Genco, the Compensation Committee

(4) Executive's failure to meet objective performance criteria of the position, provided that, in the case of a Termination of Employment during an Imminent Control Change Period (other than after a Disaggregation) this Section 7.3(c)(i)(4) shall be

inapplicable if the Imminent Change in Control culminates in a Change Date; or

(5) Executive's material breach of any of the Restrictive Covenants;

During such 10-day cure period, at the discretion of the Company, Executive shall no longer participate in the management or other operations of the Company.

(d) Meaning of "Willful". For purposes of Sections 7.3(b) and 7.3(c), no act, or failure to act, on the part of Executive shall be considered "willful" unless it is done, or omitted to be done, by Executive in bad faith or without reasonable belief that Executive's action or omission was in the best interests of the Company, or unless Executive fails to cure such breach to the fullest extent that it is curable if a cure period is provided in this Section 7.3.

(e) Procedural Requirements for Termination for Cause. Executive's Termination of Employment shall not be deemed to be for Cause under this Section 7.3 unless and until there shall have been delivered to 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 Executive and Executive is given an opportunity, together with counsel, to be heard before the Board), finding that, in the good faith opinion of the Board, Executive's acts, or failure to act, constitutes Cause and specifying the particulars thereof in detail.

During the Employment Period other than during the Current Post-Merger Period, Post-Change Period, Post-Disaggregation Period, Imminent Control Change Period or Post-Significant Acquisition Period, Executive may terminate his employment for Good Reason. Executive shall provide the Company with a Notice of Termination specifying that it is a Termination of Employment for Good Reason and stating the basis for the Termination of Employment for Good Reason.

Such Notice of Termination shall be

provided no more than a reasonable time after Executive becomes aware of the circumstances constituting Good Reason. For purposes of this

Section 7.4(b).

(1) a material adverse reduction in the nature or scope of Executive's office, position, duties, functions, responsibilities or authority (other than in a Post-Significant Acquisition Period, and other than ceasing to serve as an officer of the Company after a Disaggregation in which Genco is the Disaggregated Unit);

(2) a material reduction of Executive's salary, incentive compensation or aggregate benefits unless such reduction is part of a policy, program or arrangement applicable to peer executives of the Company and of any successor entity;

(3) the failure of any successor to the Company or Genco to assume this Agreement;

(4) a relocation (other than in a Post-Significant Acquisition Period), of more than 50 miles of (A) Executive's workplace, or (B) the principal offices of the Company or its successor (if such offices are Executive's workplace), in each case without the consent of Executive; provided, however, in both cases of (A) and (B) of this Section 7.4(b)(i)(4), such new location is farther from Executive's residence than the prior location;

(5) a requirement (other than in a Post-Significant Acquisition Period) of the greater of (A) more than 24 days of travel per year, or (B) at

least 20% more business travel than was required of Executive prior to the Applicable Trigger Date;

(7) 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 Executive retains substantially the same position (determined without regard to reporting requirements) with the Disaggregated Entity, with substantially the same compensation and benefits, in the aggregate, as immediately prior to such Disaggregation, notwithstanding Sections 7.4(b)(i)(1), 7.4(b)(i)(2) and 7.4(b)(i)(6).

(ii) Additional Basis for Good Reason During the Current Post-Merger Period. With respect to the Current Post-Merger Period, "Good Reason" shall have the meaning set forth in Section 7.4(b)(i) and shall also include any of the following which occurred prior to the Agreement Date:

(1) a material adverse alteration in the nature or scope of Executive's position, duties, functions, responsibilities or authority;

(2) a determination by Executive, made in good faith during the term of the Prior CIC Agreement and prior to the Agreement Date, that, as a result of the change in control resulting in the merger of Unicom Corporation and PECO Energy Corporation, Executive is substantially unable to perform, or that there has been a material reduction in, any of Executive's duties, functions, responsibilities or authority;

(3) a relocation of more than 50 miles of Executive's workplace, without the consent of Executive;

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

If Executive retains substantially the same position with the Disaggregated Entity as was held with respect to the Disaggregated Unit immediately prior to the Disaggregation (determined without regard to reporting requirements and determined without regard to Executive's position with respect to the Company), then (1)
Section 7.4(b)(i)(1) shall apply only with respect to Executive's office, duties, functions, responsibilities or authority as in effect at the Disaggregated Entity on the day following the Disaggregation, (2) subsections 7.4(b)(i)(4) and 7.4(b)(i)(5) shall apply only with respect to relocations or travel 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 7.4(b) to the Company or its successor shall be to the Disaggregated Entity or its successor.

(c) Limitations on Good Reason. Notwithstanding the foregoing provisions of this Section 7.4(a) or (b), no act or omission shall constitute a material breach of this Agreement by the Company, nor grounds for Termination of Employment by Executive for "Good Reason":

(1) unless Executive gives the Company 30 days' prior written notice of such act or omission and the Company fails to cure such act or omission within the 30-day period following receipt of such notice;

(2) if Executive first acquired knowledge of such act or omission more than 12 months before Executive gives the Company such notice; or

(3) if Executive has consented in writing to such act or omission in a document that makes specific reference to this Section.

(d) Notice by Executive. In the event of any Termination of Employment by Executive for Good Reason, Executive shall as soon as practicable after the expiration of the 30-day cure period referred to in Section 7.4(c) above send a Notice of Termination to the Company (and Disaggregated Entity, if applicable) detailing the events constituting such Good Reason by a Notice of Termination. Subject to the limitations in Section 7.4(c), a delay in the delivery of such Notice of Termination shall not waive any right of Executive under this Agreement.

(f) Termination for Disability: Health Care Coverage. While Executive is receiving long term disability benefits, he shall continue to participate in the health care plans under which Executive was covered immediately prior to his Termination Date. Executive's out of pocket costs (including premiums, deductibles, and co-payments) for such health care coverage shall be the same as that in effect from time to time for peer executives whose employment has been terminated on account of disability. Coverage under this Section 8.7(f) shall be provided in lieu of COBRA.

(g) Termination for Disability: Disability Benefits. The Company shall provide Executive disability and other benefits after the Termination Date pursuant to the Company's long term disability Plans in which Executive participates, as in effect from time to time; provided, however, that if the Termination Date occurs during the Current Post-Merger Period, Post-Change Period, Imminent Control Change Period that culminates in a Change Date, Post-Significant Acquisition Period or Post-Disaggregation Period, the Company shall provide Executive disability and other benefits after the Termination Date that are not less than the most favorable of such benefits then provided under Plans of the Company to disabled peer executives of the Company in effect immediately before the Termination Date.

8.8 Upon Death. If Executive's employment with the Company or Affiliate, (or, if applicable, the Disaggregated Entity) is terminated by reason of Executive's death during the Employment Period, the Company's sole obligation to Executive (and the Beneficiary) under Articles II, IV, VI and VIII shall be as set forth in this Section 8.8 (and neither Executive nor the Beneficiary shall be entitled to receive any severance payment hereunder). The remaining provisions of this Agreement shall continue to apply.

The Company shall provide the Beneficiary such survivor and other benefits (including the proceeds of any life insurance policies on Executive's life maintained by the Company on behalf of Executive under which the Beneficiary is the beneficiary) available as of the Termination Date under the Plans of the Company; provided, however, that if Executive's death occurs during the Current Post-Merger Period, Post-Change Period, Imminent Control Change Period that culminates in a Change Date, Post-Significant Acquisition Period or Post-Disaggregation Period, the Company shall provide the Beneficiary such survivor and other benefits that are not less favorable 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 Executive's death.

8.9 Timing of Severance Payments. Unless otherwise specified herein or in an applicable Plan, the amounts described in Sections 8.1(a) and (b), Sections 8.2(a)(i), (ii), (iii), (iv) and (v), Sections 8.6(a) and Section 8.7(a) and Section 8.8(a) shall be paid in cash within 30 business days of the Termination Date (provided that any amounts due under any tax-qualified plans

(under Section 401(a) of the Code) shall be paid pursuant to the terms of such plans, including payment timing and form). The severance payments described in Sections 8.1(c) and 8.2(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 Executive according to the Company's normal payroll practices at a monthly rate equal to 1/12 of the sum of (i) Executive's Base Salary 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 (if any) between the total severance payment under Sections 8.1(c) and 8.2(a)(vi), as applicable, less the total amount paid pursuant to normal payroll practices under Section 8.9(a).

8.10 Waiver and Release. Notwithstanding anything herein to the contrary, the Company shall have no obligation to Executive under Article VIII or Article IX unless and until Executive executes a release and waiver of Company and its Affiliates, in substantially the same form as attached hereto as Attachment C, or as otherwise mutually acceptable, and any revocation period with respect to such release and waiver has lapsed. Notwithstanding anything herein (whether or not during the Employment Period) or in the Key Management Severance Plan to the contrary, Executive hereby waives any right he may have at any time during the Current Post-Merger Period to terminate his employment for Good Reason, whether or not under the Key Management Severance Plan or this Agreement, as a result of any event or condition ("Waived Events") made as part of an internal structural reorganization or restructuring of Genco which results in any change or reduction or transition in the nature or scope of Executive's office, position, duties, functions, responsibilities or authority, that has occurred, exists, or occurs, or of which Executive has been or is notified, at any time during the Current Post-Merger Period, provided that any such change or reduction after the Agreement Date shall not assign Executive to a position of less status, responsibility, or authority than Executive's position on the Agreement Date. Executive also hereby agrees and acknowledges that the substitution of this Agreement for the Prior CIC Agreement (a) does not and will not give rise to Good Reason under either such agreement and (b) renders the Prior CIC Agreement null and void with no further rights or obligations thereunder. Executive will, however, retain the right to terminate his employment for Good Reason under this Agreement, as applicable, should other future events or conditions other than the Waived Events independently trigger such right (including other future events or conditions relating to a subsequent Change in Control).

8.11 Sole and Exclusive Obligations. The obligations of the Company under this Agreement with respect to the employment and any Termination of Employment of Executive shall supersede any obligations of the Company in any other plan of the Company (except to the extent the Company's obligations under such agreement are included herein) or any other agreement between Executive and the Company, including, without limitations, the Key Management Severance Plan, the Prior CIC Agreement, any other Change in Control Agreement entered into by and among Executive, Unicom Corporation, or ComEd, or any other plan or agreement (including an offer of employment or employment contract) of the Company or any Affiliates. Notwithstanding the preceding or anything in this Article VIII to the contrary, all benefits or coverage provided or amounts paid by the Company pursuant to this Article VIII

shall be reduced (but not below zero) by the same or similar benefits or coverage provided or amounts paid or payable to Executive by the Company or an affiliate on account of the Termination of Employment, pursuant to the Key Management Severance Plan or otherwise. 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, this Agreement shall govern.

ARTICLE IX
CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

9.1 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 under this Agreement or otherwise ("Potential Parachute Payment") is or will become subject to the excise tax imposed by Section 4999 of the Code or any similar tax payable under any United States federal, state, local, foreign or other law ("Excise Taxes"), then the Company shall, subject to
Section 9.2, 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 Executive makes payment to the IRS of such Excise Taxes.

9.2 Limitation on Gross-Up Payments.

(a) To the extent possible, any payments or other benefits to Executive pursuant to Article IV, Article VI and Article VII of this Agreement shall be allocated as consideration for Executive's entry into the covenants of Article IX.

(b) Notwithstanding any other provision of this Article V, if the aggregate amount of the Potential Parachute Payments that, but for this Section 9.2, 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.

9.3 Additional Gross-up Amounts. If, for any reason (whether pursuant to subsequently enacted provisions of the Code, final regulations or published rulings of the IRS, or a final judgment of a court of competent jurisdiction) the Company's independent auditors later determine that the amount of Excise Taxes payable by Executive is greater than the amount initially determined pursuant to Section 9.1, then the Company shall, subject to Sections 9.2 and 9.4, 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 9.1 or 9.4,

multiplied by

(b) the Gross-Up Multiple.

9.4 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 9.1. 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 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 9.4(d) to contest the balance of the IRS Claim,

then Executive shall pay only the amount, if any, of Excise Taxes, interest and penalties specified in the Company Certificate. In no event shall Executive pay an IRS Claim earlier than 30 business days after having given an Executive's Notice to the Company (or, if sooner, the IRS Claim Deadline).

(b) At any time after the payment by Executive of any amount of Excise Taxes, other Taxes or related interest or penalties in respect of Potential Parachute Payments (including any such amount equal to or less than the amount of such Excise Taxes specified in any Company Certificate, or IRS Claim), the Company may in its discretion require Executive to pursue a claim for a refund (a "Refund Claim") of all or any portion of such Excise Taxes, other Taxes, interest or penalties as may be specified by the Company in a written notice to Executive.

(c) If the Company notifies Executive in writing that the Company desires Executive to contest an IRS Claim or to pursue a Refund Claim, Executive shall:

(i) give the Company all information that it reasonably requests in writing from time to time relating to such IRS Claim or Refund Claim, as applicable,

(ii) take such action in connection with such IRS Claim or Refund Claim (as applicable) as the Company reasonably requests in writing from time to time, including accepting legal representation with respect thereto by an attorney selected by the Company, subject to the approval of Executive (which approval shall not be unreasonably withheld or delayed),

(iii) cooperate with the Company in good faith to contest such IRS Claim or pursue such Refund Claim, as applicable,

(iv) permit the Company to participate in any proceedings relating to such IRS Claim or Refund Claim, as applicable, and

(v) contest such IRS Claim or prosecute Refund Claim (as applicable) to a determination before any administrative tribunal, in a court of initial

jurisdiction and in one or more appellate courts, as the Company may from time to time determine in its discretion.

The Company shall control all proceedings in connection with such IRS Claim or Refund Claim (as applicable) and in its discretion may cause Executive to pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the Internal Revenue Service or other taxing authority in respect of such IRS Claim or Refund Claim (as applicable); provided that (i) any extension of the statute of limitations relating to payment of taxes for the taxable year of Executive relating to the IRS Claim is limited solely to such IRS Claim, (ii) the Company's control of the IRS Claim or Refund Claim (as applicable) shall be limited to issues with respect to which a Gross-Up Payment would be payable, and (iii) Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or other taxing authority.

(d) The Company may at any time in its discretion direct Executive to (i) contest the IRS Claim in any lawful manner or (ii) pay the amount specified in an IRS Claim and pursue a Refund Claim; provided, however, that if the Company directs Executive to pay an IRS Claim and pursue a Refund Claim, the Company shall advance the amount of such payment to Executive on an interest-free basis and shall indemnify Executive, on an after-tax basis, for any Excise Tax or income tax, including related interest or penalties, imposed with respect to such advance.

(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.

9.5 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 9.4) 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 9.4 or receipt by the IRS of an amount paid by the Company on behalf of Executive pursuant to Section 9.4, 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 9.4(d).

ARTICLE X
EXPENSES, INTEREST, DISPUTE RESOLUTION,
INDEMNIFICATION AND D&O LIABILITY INSURANCE

10.1 Enforcement and Late Payments: Under Certain Special Circumstances. If, after the Agreement Date and during or on account of the Current Post-Merger Period, Post-Change Period, Imminent Control Change Period that culminates in a Change Date, Post-Significant Acquisition Period or Post-Disaggregation Period, Executive incurs reasonable legal fees or other expenses (including arbitration costs and expenses under Section 10.4) 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 10.1(a)) for such fees and expenses, subject to the following.

(a) 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.

(b) 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.

10.2 Negotiation of Agreement. The Company shall reimburse Executive for 50% of the reasonable attorney fees and expenses incurred by Executive in negotiating and drafting this Agreement for up to the first $100,000 of such reasonable attorney fees and expenses so incurred. The Company's obligation under this Section 10.2 shall not exceed $50,000.

10.3 Interest: Under Certain Special Circumstances. If the Company does not pay any cash amount due to Executive under Sections 8.2, 8.3, 8.4 or Article IX 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 Executive shall not be entitled to interest on any Gross Up Payment.

10.4 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 IX or to an alleged breach of the Restrictive Covenants in Article XII) 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 commercial 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 14.12 below. The decision of the arbitrator shall be final and binding upon the parties and a judgment thereon may be entered in the highest court of a forum, state or federal, having jurisdiction. The expenses of the arbitration shall be borne according to
Section 10.1, if applicable and, if Section 10.1 is not applicable, each party shall be responsible for its own costs including attorneys' fees. 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 10.4 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 10.4 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.

10.5 Indemnification. Executive shall be indemnified and held harmless by the Company on the same terms as other senior executives and 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 Agreement Date if 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 whether civil, criminal, administrative or investigative, and whether formal or informal, by reason of the fact that Executive is or was, or had agreed to become, a director, officer, employee, agent, or fiduciary of the Company or any other entity which 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 Executive or to which Executive may become subject for any reason. A Proceeding shall not include any proceeding to the extent it concerns or relates to a matter described in Section 10.1 (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 advance such expenses to Executive or pay such expenses for Executive, all in advance of the final disposition of any such matter.

10.6 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 the same terms as those provided to senior executive officers and directors of the Company.

ARTICLE XI
NO SET-OFF OR MITIGATION

11.1 No Set-off by Company.

(a) 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. Time is of the essence in the performance by the Company of its obligations under this Agreement.

(b) 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.

11.2 No Mitigation.

(a) 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.

(b) 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 employer or self-employment.

ARTICLE XII
RESTRICTIVE COVENANTS

12.1 Confidential Information. Executive acknowledges that in the course of performing services for the Companies and Affiliates, he 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 to the public or within the relevant trade or industry 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 that Executive knew, or should have known about at the time of such disclosure; or (iii) information approved for release by written authorization of the Company. 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. Executive agrees that, (a) except as required by the duties of Executive's employment with the Company or any of its Affiliates (including pursuant to this Agreement), (b) except in connection with enforcing Executive's rights under this Agreement, and/or (c) except if compelled by a court or governmental agency, provided in each case of (b) and
(c) above that prior written notice is given to Company, Executive will not, without the written consent of Company, willfully disseminate or otherwise disclose, directly or indirectly, any Confidential Information obtained during his 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). Nothing in this Section 12.1 prohibits Executive from reporting any suspected instance of a nuclear safety concern or any safety concern of any nature related to the operation of a nuclear power station to the United States Nuclear Regulatory Commission ("NRC"), the United States Department of Labor, or any other state or federal government agency; nor does this Section 12.1 prohibit or discourage Executive from providing information to the NRC, or to any state or federal agency or from testifying in any civil or criminal proceeding.

12.2 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 12.2 shall not preclude Executive from (i) being an employee of, or consultant to, any business unit of a Competitive Business if (A) such business unit does not qualify as a Competitive Business in its own right and (B) 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, (ii) being a consultant to, an advisor to, or an employee of a governmental regulatory agency,
(iii)serving on the boards of colleges, universities or professional societies (e.g., the American Nuclear Society) (and related committees or organizations thereof), (iv) serving on the following industry boards (or related committees or organizations thereof): WANO (World Association of Nuclear Operators), INPO (Institute of Nuclear Professional Operators), NEI (Nuclear Energy Institute), EEI (Edison Electric Institute) and EPRI (Electric Power Research Institute) or (v) with the approval of the Chief Executive Officer of the Company, serving as a non-employee director of a Competitive Business.

(b) make or retain any financial investment, whether in the form of equity or debt, or own any interest, in any Competitive Business. Nothing in this subsection shall, however, restrict Executive from making an investment in any Competitive Business if

such investment does not (i) represent more than 1% of the aggregate market value of the outstanding capital stock or debt (as applicable) of such Competitive Business, (ii) give Executive any right or ability, directly or indirectly, to control or influence the policy decisions or management of such Competitive Business, and (iii) create a conflict of interest between Executive's duties under this Agreement and his interest in such investment.

12.3 Non-Solicitation. During the period beginning on the Agreement Date and ending on the second anniversary of any Termination Date, whether or not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation, Executive shall not, directly or indirectly:

(a) other than in connection with the good-faith performance of his duties as an officer of the Company, cause or attempt to cause any employee or agent of the Company to terminate his or her relationship with the Company;

(b) employ, engage as a consultant or adviser, or solicit the employment or engagement as a consultant or adviser, of any employee or agent of the Company (other than by the Company or its Affiliates), or cause or attempt to cause any Person to do any of the foregoing;

(c) establish (or take preliminary steps to establish) a business with, or cause or attempt to cause others to establish (or take preliminary steps to establish) a business with, any employee or agent of the Company, if such business is or will be a Competitive Business; or

(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 Executive's knowledge, a material customer or material supplier of, or maintained a material business relationship with, the Company.

Notwithstanding anything herein to the contrary, Executive may respond to an unsolicited request for an employment reference regarding any employee or agent of the Company (or Affiliate) from a third party by providing a reference setting forth Executive's personal views about such employee or agent.

12.4 Intellectual Property. During the period of Executive's employment with the Company and any Affiliate, and thereafter upon the Company's request, whether or not after a Change in Control, Imminent Control Change, Significant Acquisition or Disaggregation, Executive shall disclose immediately to the Company all ideas, inventions and business plans that he makes, conceives, discovers or develops alone or with others during the course of his employment with the Company or during the one year period following Executive's Termination Date, including any inventions, modifications, discoveries, developments, improvements, computer programs, processes, products or procedures (whether or not protectable upon application by copyright, patent, trademark, trade secret or other proprietary rights) ("Work Product") that: (i) relate to the business of the Company or any customer or supplier to the

Company or any of the products or services being developed, manufactured, sold or otherwise provided by the Company or that may be used in relation therewith; or (ii) result from tasks assigned to Executive by the Company; or (iii) result from the use of the premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company. Executive agrees that any Work Product shall be the property of the Company and, if subject to copyright, shall be considered a "work made for hire" within the meaning of the Copyright Act of 1976, as amended (the "Act"). If and to the extent that any such Work Product is not a "work made for hire" within the meaning of the Act, Executive hereby assigns to the Company all right, title and interest in and to the Work Product, and all copies thereof, and the copyright, patent, trademark, trade secret and all proprietary rights in the Work Product, without further consideration, free from any claim, lien for balance due or rights of retention thereto on the part of Executive.

(a) The Company hereby notifies Executive that the preceding paragraph does not apply to any inventions for which no equipment, supplies, facility, or trade secret information of the Company was used and which was developed entirely on 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 Executive for the Company.

(b) Executive agrees that upon disclosure of Work Product to the Company, Executive will, during his 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 his agent and attorney-in-fact, to act for and on his 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.

(d) If Executive is required to execute documents or perform acts after the Termination Date pursuant to this Section 12.4, Executive shall be entitled to receive prompt reimbursement for all reasonable out-of-pocket costs and expenses necessitated by compliance with this Section 12.4, including travel expenses but not attorneys' fees.

12.5 Non-Disparagement. During the period beginning on the Termination Date and ending on the second anniversary of the Termination Date, Executive shall not (a) make any written or oral statement that brings the Company or any of its Affiliates or the employees, officers or agents of the Company or any of its Affiliates into disrepute, or tarnishes any of their images or reputations or (b) publish, comment upon or disseminate any statements suggesting or accusing the Company or any of its Affiliates or any agents, employees or officers of the Company or any of its Affiliates of any misconduct or unlawful behavior. This Section 12.5 shall not be deemed to be breached by testimony of Executive given in any judicial or governmental proceeding which Executive reasonably believes to be truthful at the time given or by any other action of Executive which he reasonably believes is taken in accordance with the requirements of applicable law or administrative regulation. Nothing in this
Section 12.5 prohibits Executive from reporting any suspected instance of a nuclear safety concern or any safety concern of any nature related to the operation of a nuclear power station to the United States Nuclear Regulatory Commission ("NRC"), the United States Department of Labor, or any other state or federal government agency; nor does this Section 12.5 prohibit or discourage Executive from providing information to the NRC, or to any state or federal agency or from testifying in any civil or criminal proceeding.

12.6 Reasonableness of Restrictive Covenants.

(a) Executive acknowledges that the covenants contained in Sections 12.1, 12.2, 12.3, 12.4 and 12.5 are reasonable in the scope of the activities restricted, the geographic area covered by the restrictions, and the duration of the restrictions, and that such covenants are reasonably necessary to protect the Company's legitimate interests in its Confidential Information and in its relationships with its employees, customers and suppliers. Executive further acknowledges such covenants are essential elements of this Agreement and that, but for such covenants, the Company would not have entered into this Agreement.

(b) The Company and Executive have each consulted with their respective legal counsel and have been advised concerning the reasonableness and propriety of such covenants. Executive acknowledges that his observance of the covenants contained in Sections 12.1, 12.2, 12.3, 12.4 and 12.5 will not deprive Executive of the ability to earn a livelihood or to support his dependents.

12.7 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 12.1, 12.2, 12.3 and 12.4 the parties agree that it would be impossible to measure solely in money the damages which the Company would suffer if Executive were to breach any of his obligations under such Sections. Executive acknowledges that any breach of any provision of such Sections would irreparably injure the Company. Accordingly, Executive agrees that if he 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 XII 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 XII shall survive any Termination of Employment without regard to (i) the reasons for such termination or (ii) the expiration of the Employment Period.

12.8 Breach of Covenants.

(a) In the event Executive breaches a Restrictive Covenant, the Company shall be entitled to require a Forfeiture (as defined below) if and only if a Forfeiture Event (as defined below) has occurred.

(b) A "Forfeiture Event" means that both of the following have occurred:

(i) Executive shall have committed a willful and material breach of any of the covenants contained in this Article XII, or Executive shall have failed to cure (to the fullest extent curable) a non-willful breach of any of such covenants within 10 days after his receipt of a written notice thereof from the Company; provided no act or failure to act (including simple negligence or an error in judgment) shall be deemed a willful breach of a Restrictive Covenant if such act or failure to act was done in good faith, with a reasonable belief that the act, or failure to act, was in the best interest of the Company or was required by applicable law or administrative regulations, and was not done primarily to benefit Executive.

(ii) In an action brought at any time but no later than three years after the Termination Date, the Company shall have obtained a final judicial determination (or, if the Company reasonably determines, based upon the advice of counsel, that it is more likely than not that each of the Circuit Court of Cook County, Illinois and the United States District Court for the Northern District of Illinois will decline to adjudicate the issue, a final decree in an arbitration proceeding conducted in accordance with the rules of the American Arbitration Association, with such arbitration proceeding to be conducted in Chicago, Illinois before a panel of three arbitrators) to the effect that a Forfeiture Event has occurred and that the occurrence of a Forfeiture is appropriate and consistent with the requirements and procedures set forth in this Agreement.

(c) A Forfeiture means any or all of the following, in the discretion of the Company:

(i) Discontinuance of any and all payments and benefits provided to Executive pursuant to Articles VIII, Article IX, and any other provision of this Agreement;

(ii) Termination of any Stock Options then held by Executive, whether or not then exercisable;

(iii) Requiring Executive to:

(1) Repay to the Company all amounts (if any) previously received by Executive pursuant to any provision of Articles VIII and/or IX on or after the first date on which the Executive breached any of the covenants contained in this Article XII ("Breach Date");

(2) Repay to the Company all amounts (if any) previously received by Executive pursuant to the Enhanced SERP at any time on or after the Termination Date;

(3) Pay to the Company an amount equal to the aggregate "spread" on all Stock Options exercised on or after the Breach Date (for this purpose "spread" in respect of any Stock Option shall mean the product of the number of shares as to which such Stock Option has been exercised on or after the Breach Date multiplied by the difference between the closing price of the common stock on the exercise date (or if the common stock did not trade on the New York Stock Exchange on the exercise date, the most recent date on which the common stock did so trade) and the exercise price of the Stock Option); and

(4) Repay to the Company any other amount that it paid to Executive on or after the Breach Date which Executive would not have been entitled to receive if the Company had terminated the employment of Executive for Cause as of the Breach Date.

ARTICLE XIII
NON-EXCLUSIVITY OF RIGHTS

13.1 Other Rights. Except as expressly provided in Section 8.11 or 12.8 or elsewhere in this Agreement, this Agreement shall not prevent or limit Executive's continuing or future participation in any benefit, bonus, incentive or other Plans provided by the Company and for which Executive may qualify, nor shall this Agreement limit or otherwise affect such rights as Executive may have under any other agreements with the Company. Amounts which are vested benefits or which Executive is otherwise entitled to receive under any Plan and any other payment or benefit required by law at or after the Termination Date shall be payable in accordance with such Plan or applicable law except as expressly modified by this Agreement.

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

ARTICLE XIV
MISCELLANEOUS

14.1 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.

14.2 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.

14.3 Affiliates. To the extent that immediately prior to the Applicable Trigger Date, 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 6.8(a), (a)(i) and (a)(ii) and the other Sections of this Agreement referring to benefits to which Executive may be entitled shall be read to refer to such Affiliate.

14.4 No Double Payment. Notwithstanding any other provision of this Agreement, Executive shall not be entitled to payment under both this Agreement and the Key Management Severance Plan for the same type of benefit or payment. Amounts paid hereunder shall be reduced by amounts paid under the Key Management Severance Plan for the same type of benefit or payment.

14.5 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"). Executive, without the consent of any prior Beneficiary, may change his designation of Beneficiary or Beneficiaries at any time or from time to time by submitting to the Company a new designation in writing. If none is so designated, Executive's estate shall be his or her Beneficiary.

14.6 Non-Alienation of Benefits. Benefits payable under this Agreement shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind, either voluntary or involuntary, before actually being received by Executive, and any such attempt to dispose of any right to benefits payable under this Agreement shall be void.

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

14.8 Amendments. This Agreement shall not be amended or modified except by written instrument executed by the Company and Executive.

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

14.17 Entire Agreement.

Attachment A

Special Restricted Stock Award Agreement

Exelon Corporation, a Pennsylvania corporation (the "Company"), hereby grants to Oliver D. Kingsley, Jr.,(the "Holder") pursuant to the provisions of the Exelon Corporation Long-Term Incentive Plan, as amended and restated effective October 20, 2000 (the "Plan"), a restricted stock award (the "Award") of thirty-five thousand (35,000) restricted shares of the Company's Common Stock, without par value ("Common Stock"), upon and subject to the terms and conditions set forth below. Unless otherwise noted, capitalized terms not defined herein shall have the meanings specified in the Plan.

1. Award Subject to Employment Agreement.

The Award shall be subject to all the terms of this Agreement, the Plan, and that certain Employment Agreement dated as of September 5, 2002 among the Company, Exelon Generation Company, LLC and the Holder (the "Employment Agreement") to which this Award is attached as Attachment A.

2. Rights as a Stockholder.

The Holder shall have the right to vote the shares of Common Stock subject to the Award and to receive dividends and other distributions thereon unless and until, and only to the extent, such shares are forfeited pursuant to
Section 3.2 hereof; provided, however, that a dividend or distribution with respect to shares (including, without limitation, a stock dividend or stock split), other than a regular cash dividend, shall be delivered to the Company (and the Holder shall, if requested by the Company, execute and return one or more irrevocable stock powers related thereto) and shall be subject to the same restrictions as the shares of Common Stock with respect to which such dividend or other distribution was made.

3. Restriction Period -- Vesting Dates and Vesting.

3.1 Vesting Dates.

Subject to Section 3.2 hereof, twenty percent (20%) of the total shares of Common Stock subject to the Award shall vest on January 1, 2003, and an additional twenty percent (20%) shall vest on each of the next four anniversaries of January 1, 2003, provided Executive is employed by the Company or an Affiliate on such anniversary. Upon Holder's Termination of Employment (as such term is defined in the Employment Agreement) by Holder for Good Reason (as such term is defined in the Employment Agreement), death or Disability (as such term is defined in the Employment Agreement) or by the Company other than for Cause (as such term is defined in the Employment Agreement), any non-vested shares then subject to the Award shall immediately become fully vested and nonforfeitable.

3.2 Forfeiture of Non-Vested Shares.

If, prior to the date on which all of the shares of Common Stock subject to the Award become vested, the Holder's employment is terminated by the Company for Cause (as such term is defined in the Employment Agreement), the non-vested shares shall be forfeited by the Holder if not vested by the Date of Termination (as such term is defined in the Employment Agreement).

4. Termination of Award.

In the event that Holder shall forfeit any shares of Common Stock subject to the Award pursuant to Section 3.2, this Award shall immediately terminate. The Holder shall, upon the Company's request, promptly return this Agreement to the Company for cancellation. Such cancellation shall, however, be effective regardless of whether the Holder returns this Agreement. Cancellation of this Agreement shall not effect the Holder's right hereunder with respect to any vested shares.

5. Additional Terms and Conditions of Award.

5.1 Nontransferability of Award.

This Award may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to sell, transfer, assign, pledge, hypothecate or encumber, or otherwise dispose of this Award or any shares of Common Stock subject hereto that haven not vested and been issued pursuant to Section 5.5, this Award and any obligation of the Company with respect to the shares subject hereto shall immediately become null and void.

5.2 Withholding Taxes.

(a) As a condition precedent to the delivery to the Holder of any shares of Common Stock subject to the Award, the Holder shall, upon request by the Company, pay to the Company (or shall cause a broker-dealer on behalf of the Holder to pay to the Company) such amount of cash as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the "Required Tax Payments") with respect to the Award. If the Holder shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to the Holder.

(b) The Holder may elect to satisfy his obligation to advance the Required Tax Payments by any of the following means: (1) a cash payment to the Company pursuant to Section 5.2(a), (2) delivery to the Company of previously owned whole shares of Common Stock (which the Holder has held for at least six months prior to the delivery of such shares or which the Holder purchased on the open market and for which the Holder has good title, free and clear of all liens and encumbrances) having a Fair Market Value, determined as of the date the obligation to withhold or pay taxes first arises in connection with the Award (the "Tax Date"), equal to the Required Tax Payments, (3) authorizing

the Company to withhold from the shares of Common Stock otherwise to be delivered to the Holder pursuant to the Award a number of whole shares of Common Stock having a Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments, (4) a cash payment by a broker-dealer acceptable to the Company through whom the Holder has sold the shares with respect to which the Required Tax Payments have arisen or (5) any combination of (1), (2) and (3). The Committee shall have sole discretion to disapprove of an election pursuant to any of clauses (2)-(5). Shares of Common Stock to be delivered or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments. Any fraction of a share of Common Stock which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder. No certificate representing a share of Common Stock shall be delivered until the Required Tax Payments have been satisfied in full.

5.3 Adjustment.

In the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Common Stock other than a regular cash dividend, the number and class of securities subject to the Award shall be adjusted as determined by the Committee. If any adjustment would result in a fractional security being subject to the Award, the Company shall pay the Holder, in connection with the vesting, if any, of such fractional security, an amount in cash determined by multiplying (i) such fraction (rounded to the nearest hundredth) by (ii) the Fair Market Value on the relevant vesting date. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

5.4 Compliance with Applicable Law.

The Award is subject to the condition that if the listing, registration or qualification of the shares subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of shares hereunder, the shares of Common Stock subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval.

5.5 Custody and Delivery of Shares.

The Company shall hold the certificate or certificates representing the shares of Common Stock subject to the Award until such Award shall have vested pursuant to Section 3.1 hereof. Subject to Section 5.2, as soon as practicable after the shares of Common Stock subject to the Award become vested, the Company shall deliver or cause to be delivered one or more certificates issued in the Holder's name representing the number of vested shares and destroy the stock power or powers relating to the vested shares. The Company shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, except as otherwise provided in Section 5.2.

5.6 Award Confers no Rights to Continued Employment.

In no event shall the granting of the Award or its acceptance by the holder give or be deemed to give the Holder any right to continued employment by the Company or any affiliate of the Company.

5.7 Decisions of Committee.

The Committee shall have the right to resolve all questions which may arise in connection with the Award. Any interpretation, determination or other action made or taken by the Committee regarding the Plan or this Agreement shall be final, binding and conclusive.

5.8 Agreement Subject to the Plan.

This Agreement is subject to the provisions of the Plan and shall be interpreted in accordance therewith.

5.9 Investment Representation.

The Holder hereby represents and covenants that (a) any share of Common Stock acquired upon the vesting of the Award will b acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), unless such acquisition has been registered under the Securities Act and any applicable state securities law; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exception from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Holder shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of acquisition of any shares hereunder or (y) is true and correct as of the date of any sale of any such shares, as applicable.

6. Miscellaneous Provisions.

6.1 Meaning of Certain Terms.

As used herein, the following terms shall have the respective meanings set forth below:

"Fair Market Value" means the closing transaction price of a share of Common Stock, as reported on the New York Stock Exchange Composite Transactions on the date in question or, if there shall be no reported transaction for such date, on the next preceding date for which a transaction was reported.

As used herein, "employment by the Company" shall include employment by a corporation which is a "subsidiary corporation" of the Company, as such term is defined in Section 424 of the Code. References in this Agreement to sections of the Code shall be deemed to refer to any successor section of the Code or any successor internal revenue law.

6.2 Successors.

This Agreement shall be binding upon and inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of the Holder, acquire any rights hereunder in accordance with this Agreement, the Employment Agreement or the Plan.

The notice, request or other communication shall be deemed to be received upon personal delivery, upon confirmation of receipt of facsimile transmission, or upon receipt by the party entitled thereto if by United States mail or express courier service; provided, however, that if a notice, request or other communication is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.

6.4 Governing Law.

This Agreement, the Award and all determinations made and actions taken pursuant hereto and thereto, to the extent not otherwise governed by the laws of the United States, shall be governed by the laws of the Commonwealth of Pennsylvania and construed in accordance therewith without giving effect to conflicts of laws principles.

Executive's Enhanced SERP is fully vested, subject to the provisions of Article XII of the Agreement.

If, prior to the date Executive would be eligible to receive an annuity under the Commonwealth Edison Service Annuity System (the "Service Annuity System") Executive (a) becomes entitled to payment under the Enhanced SERP or (b) dies while employed, then, as applicable, Executive shall be entitled to elect payment in the form of a service annuity or a Marital Annuity2, or if Section 8.2 applies, a lump sum in accordance with Section 8.2, or his surviving spouse shall be immediately entitled to a surviving spouse benefit. Any annuity payment shall be determined as though he (or his surviving spouse) were entitled to such annuity under the Service Annuity System, taking into account Executive's service as credited above, and under Section 8.2(a)(iv), if applicable.

2 The Marital Annuity, which is an automatic election under the SERP, provides a pension benefit to Executive during his lifetime and if he dies after he retires and his spouse to whom he was married when the pension benefits commenced survives him, such surviving spouse will be paid a reduced benefit (generally 50% of the pension benefit payable while both Executive and his surviving spouse were living) for the remainder of her lifetime. Generally, the Marital Annuity will be equal to 50% of Executive's regular pension benefit. The actual amount payable to Executive and Executive's spouse will be affected by his age, his spouse's age and the amount of the Enhanced SERP. Unless Executive is entitled to choose and does choose a lump sum Enhanced SERP payment under this Agreement (in which case no spousal consent is required), if Executive does not choose the Marital Annuity, he must obtain his spouse's written consent and complete the appropriate documents during the 90 day period before his Enhanced SERP payments begin.

If all or any part of this Agreement is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any other portion of this Agreement. Any section or a part of a section declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of the section to the fullest extent possible while remaining lawful and valid.

7. Amendment. This Agreement shall not be altered, amended, or modified except by written instrument executed by the Company and Executive. A waiver of any portion of this Agreement shall not be deemed a waiver of any other portion of this Agreement.

9. Headings. The headings of this Agreement are not part of the provisions hereof and shall not have any force or effect.

10. Applicable Law. The provisions of this Agreement shall be interpreted and construed in accordance with the laws of the State of Illinois without regard to its choice of law principles.
