Outstanding and Uncompleted Contract or Agreement Entered by the Parent Holding Company or any Subsidiary Thereof Relating to the Acquisition of any Securities: On November 25, 2003, Exelon Generation Company, LLC, Reservoir Capital Group (Reservoir) and Sithe Energies, Inc. completed a series of transactions resulting in Generation and Reservoir each indirectly owning a 50% interest in Sithe with put and call options that could result in either party owning Sithe outright. While Generation's intent is to fully divest Sithe, the timing of the put and call options vary by acquirer and can extend through March 2006. The pricing of the put and call options is dependent on numerous factors, such as the acquirer, date of acquisition and assets owned by Sithe at the time of exercise. Currently, Sithe has a total generating capacity of 1,097 MWs in operation and 228 MWs under construction. See 2003 Exelon's Annual Report on Form 10-K for a further discussion of these transactions. Exelon Corporation (Exelon) and Exelon Generation Company, LLC (Generation), have commenced the process of an orderly transition out of the ownership of Boston Generating, LLC (BG) and the Mystic 8 and 9 and Fore River generating projects. Exelon's decision to transition out of the projects was made as a result of its evaluation of the projects and discussions with the lenders under BG's $1.25 billion credit facility, which was entered into primarily to finance the development and construction of the generating projects. 123

(c) Computation Period: All Consolidated Return Years to which this agreement applies. (d) Consolidated Return: The consolidated federal income tax return of the Parent Group. (e) Consolidated Return Year: Any tax return period for which Parent or any Subsidiary is or may be included in a Consolidated Return filed by Parent. (f) Consolidated Tax: The aggregate tax liability for a tax year, being the tax shown on the consolidated return and any adjustments thereto thereafter determined. (g) Corporate Taxable Income: The amount of taxable income or loss of Subsidiary for a tax year, computed as though such Subsidiary had filed a separate return on the same basis as used in the Consolidated Return, except that dividend income from Subsidiaries shall be disregarded, and other intercompany transactions eliminated in the Consolidated Return shall be given appropriate effect. It shall be further adjusted to allow for applicable rights accrued to the Subsidiary under paragraph (c) (4) of Title 17, Section 250.45 of the Code of Federal Regulations, on the basis of other tax years, including net operating loss carrybacks and net operating loss carryforwards to the extent such net operating loss carryforwards or net operating loss carrybacks would have been permitted under the Code had the Subsidiary filed a separate return. If a Subsidiary is a member of the Affiliated Group for only part of a tax year, that period will be deemed to be its tax year for all purposes under this Agreement. (h) Parent Tax Benefit: The excess of the Parent's Separate Return Tax over the amounts allocated to Parent pursuant to Section 4 (other than paragraph (c) thereof). (i) Regulations: The Treasury Regulations promulgated under the Code. (j) Separate Return Tax: The tax (net of allowable credits) on the Corporate Taxable Income of Parent or any Subsidiary computed as though such entity were not a member of a consolidated group. Separate Return Tax may not be negative. Section Two: Consolidated Return Election Parent shall file a Consolidated Return for each taxable period in respect of which this Agreement is in effect and for which Parent and one or more of the Subsidiaries are required or permitted to file a consolidated federal income tax return. Each Subsidiary hereby irrevocably designates Parent as its agent for the purpose of taking any and all actions necessary or incidental to the filing of any Consolidated Return, and further agrees to furnish Parent with any and all information and to take any and all actions as Parent may reasonably request that is necessary or appropriate for the proper filing of a Consolidated Return or for implementing the provisions of this Agreement. Each Subsidiary agrees that it will join in the Consolidated Returns to the extent that such Subsidiary is required or permitted to do so by the Code. Entities which are disregarded for federal income tax purposes pursuant to Section 7701 of the Code and Treas. Reg. ss. 301.7701-2 shall be treated for all purposes of the Agreement as if they were separate incorporated subsidiaries and each such entity is included as a "Subsidiary" as that term is used in this Agreement. 125

Section Three: Liability for Consolidated Federal Income Tax As between the parties hereto Parent agrees to pay the Consolidated Tax of the Affiliated Group for Consolidated Return Years and each Subsidiary agrees to make such payments to Parent as shall be required pursuant to Section 5 hereof. The Parent shall at all times be responsible to pay its Separate Return Tax. Section Four: Allocation of Consolidated Federal Income Tax Liability (a) The Consolidated Tax (other than alternative minimum tax) shall be allocated among the members of the Affiliated Group having a positive Separate Return Tax as provided below. The allocation of the Consolidated Tax pursuant to this section is intended to comply with Title 17, Section 250.45(c)(4) of the Code of Federal Regulation, Section 1552(a)(2) of the Code and Treasury Regulation Sections 1.1552-1(a)(2) and 1.1502-33(d)(2). In general, such method allocates Consolidated Tax (other than alternative minimum tax) among Subsidiaries having positive Separate Return Taxes in accordance with such positive Separate Return Taxes. Net operating losses of Subsidiaries not having positive Separate Return Taxes are deemed to be carried over or carried back by the Subsidiaries to the extent permissible had the Subsidiaries filed separate returns. Such net operating losses potentially serve to reduce allocations of Consolidated Tax to such Subsidiaries in subsequent taxable years in which the Subsidiaries have positive Separate Return Taxes, or to reduce allocations of Consolidated Tax in prior years in which the Subsidiaries had positive Separate Return Taxes. Consistently therewith, Consolidated Tax (other than alternative minimum tax) shall be allocated as follows: Step 1 - Preliminary Allocation. Each Subsidiary with a positive Separate Return Tax shall be allocated its share of the Consolidated Tax based on the ratio which the Separate Return Tax of the Subsidiary bears to the aggregate Separate Return Tax of all Subsidiaries with a positive Separate Return Tax. Step 2 - Adjusting for Net Operating Loss Carrybacks. If a Subsidiary has negative Corporate Taxable Income for a taxable year in the Computation Period which, had it filed separate returns, under the rules of the Code could have been carried back to a prior year in the Computation Period in which it had positive Corporate Taxable Income (the "Carryback Year"), the Separate Return Tax of such Subsidiary for the Carryback Year (and, to the extent required, for subsequent years) shall be recalculated taking such loss carryback into account. Consolidated Tax for the Carryback Year (and, to the extent required, for subsequent years) shall be reallocated in accordance with the provisions of this Section 4. Step 3 - Allocation Cap. A Subsidiary's allocation of Consolidated Tax under Step 1 may not exceed the excess if any of (a) the aggregate Separate Return Tax of the Subsidiary for the Computation Period (including the current year), determined as if the Subsidiary had filed separate returns, over (b) the total amount of Consolidated Tax allocated to the Subsidiary for the Computation Period (except the current year). Step 4 - Reallocation of Capped Amounts. To the extent that the Consolidated Tax allocated to a Subsidiary under Step 1 exceeds the limitation under Step 3, the excess shall be allocated among the remaining Subsidiaries in proportion to (but not to exceed the amount of) each Subsidiary's excess, if 126

any, of (a) the aggregate Separate Return Tax of the Subsidiary for the Computation Period (including the current year), determined as if the Subsidiary had filed separate returns, over (b) the total amount of Consolidated Tax allocated to the Subsidiary for the Computation Period (including for the current year only the amount allocated under Step 1). Step 5 - Reallocation of Excess Capped Amounts. Consolidated Tax which is allocated away from a Subsidiary under Step 3 and is not allocated to other Subsidiaries under Step 4 shall be allocated to the Parent. (b) If a consolidated current alternative minimum tax liability exists, such liability (as well as any associated minimum tax credit) will be allocated to the members by multiplying the consolidated alternative minimum tax by a fraction, the numerator of which is the separate adjusted alternative minimum tax of the member for the year, and the denominator of which is the sum of each member's separate alternative minimum tax for the year. The allocation of alternative minimum tax provided for in this paragraph is intended to comply with the principles set forth in Proposed Regulation Section 1.1502-55. (c) To the extent there is a Parent Tax Benefit, the amount of such Parent Tax Benefit shall be allocated to those Subsidiaries who have positive Separate Return Tax liabilities and correspondingly allocated away from the Parent. Any such allocation to the Subsidiaries' shall be made among the Subsidiaries in proportion to the amount of the Subsidiaries' Separate Return Tax liabilities. (d) All recapture of previously claimed tax credits shall be assessed against the member that generated the credits. (e) Each Subsidiary will be allocated the material effects of any particular features of the tax laws applicable to them. Section Five: Payments of Taxes To the extent any Subsidiary is allocated any share of the Consolidated Tax under Section 4, such amount shall be paid to the Parent before thirty days following the earlier of (i) the date on which the Consolidated Return is filed or (ii) the date, following the close of such taxable year, on which Parent notifies a Subsidiary of Parent's final determination of the liability of such Subsidiary. To the extent any Consolidated Tax previously allocated to a Subsidiary is reallocated to the Parent or another Subsidiary under Section 4(a), Step 2, the Subsidiary to whom the Consolidated Tax was previously allocated shall be entitled to receive payment from the entity to which the Consolidated Tax is reallocated under said Section. Payment shall be made within thirty days of the date on which Parent notifies a Subsidiary of Parent's final determination of the liability of such Subsidiary. Section Six: Estimated Tax Payments For purposes of computing estimated tax payments, the methodology provided in Section 4 shall be applied on each due date for payments of any estimated tax under Section 6655 of the Code (or any applicable state or local tax provision). If the application of such provisions results in a payment due to the Parent, such Subsidiary shall remit such amount to the Parent within fifteen days of the due date for payments of estimated tax under Section 6655 of the Code (or any applicable state or local tax provision). Any estimated tax 127

payments made by a Subsidiary to Parent under this Section 6 for any taxable year shall be applied to reduce the amount, if any, owing by such Subsidiary to Parent under Section 5 for that year. If the sum of the payments made by a Subsidiary under this Section 6 for any taxable year exceeds the amount owing by such Subsidiary to Parent under Section 5 for that taxable year, Parent shall repay the excess to Subsidiary within thirty days after the Parent Group's consolidated federal income return for that year is filed. The same rules shall apply with respect to estimated tax payments for state and local income taxes for which the Parent Group or any member of the Parent Group files income tax returns on a combined, unitary, consolidated or similar basis, taking into account the provisions of Section Eleven of this Agreement with respect to determining any Subsidiaries state tax liability for the applicable period. Section Seven: Carrybacks (a) In the event that the Consolidated Return shows consolidated net operating loss (as that term is defined in Section 1.1502-21(f) of the Treasury Regulations) or a credit against federal income tax for any taxable year and that consolidated net operating loss or tax credit is carried back to and absorbed in a prior taxable year of Parent or any member of the Affiliated Group, then the allocable share of such tax liability for the prior taxable year shall be recomputed pursuant to Section 4 accordingly, and the amount of the liabilities and payments determined under this Agreement shall be adjusted to conform to those recomputations. The determination as to whether a net operating loss or credit is carried back shall be entirely within the discretion of Parent. (b) Parent shall be responsible for carrying out any recomputations required by Section Seven and shall promptly give each Subsidiary notice of any conforming adjustment of affected liabilities under Section Four of this Agreement. Within 10 days following the giving of that notice, each Subsidiary shall pay Parent or Parent shall pay such Subsidiary, as the case may be, the amount of any payment due in accordance with Section Five of this Agreement resulting from any recomputations done in accordance with Section Seven, as reflected in the notice. (c) This Agreement shall have no application to the carryback of a net operating loss or credit from a separate return year (within the meaning of Section 1.1502-1(e) of the Treasury Regulations) of a Subsidiary or another affiliated group of which a Subsidiary is a member, as the case may be, to any taxable year of the Parent group. Section Eight: Interest If any payment required to be made pursuant to Section 5, 6, or 7 of this Agreement is not made within the time periods specified in those Sections, the delinquent payment shall bear interest from its due date until the date of actual payment at the rate (or rates) charged by the Internal Revenue Service on underpayments of tax for the periods in question. Section Nine: Responsibility for Tax Calculations and Disputes The tax department of Parent shall be responsible for preparing all calculations required under this Agreement. The Vice President of Taxes and General Tax Officer of Exelon shall review and approve each calculation prepared by the tax department, and shall be responsible for resolving any disputes regarding such calculations. 128

All disputes regarding application of the procedures set forth in this Agreement shall be resolved by the Vice President of Taxes and General Tax Officer of Parent in conjunction with such other members of Parent as he (or she) shall deem necessary or appropriate. Section Ten: Effective Date This Agreement shall be effective for taxable years of the Parent Group beginning after 2002. Section Eleven: State Taxes (a) State and local income taxes (and all other income taxes) shall be borne by the entity (including entities that are "disregarded entities" for federal income tax purposes) that incurs such taxes, except as provided below. (b) For those state and local jurisdictions in which the Parent or any member of the Parent Group files income tax returns on a combined, unitary, consolidated or similar basis, (i) the total liability shown on each such return shall be paid in full by Parent or such member of the Parent Group filing such combined, unitary or consolidated return; (ii) the tax liability pursuant to each combined, consolidated or unitary return shall be allocated in a manner that is consistent with the manner set forth in Section 4, provided however, that allocations shall be made only to those entities which have nexus to the applicable state for whom tax is being allocated; and (iii) payments among members included in any such combined, consolidated or unitary filings of amounts so allocated shall be made consistently with the provisions of Section Five. For purposes of this Section 11 only, the terms "Separate Return Tax", "Consolidated Tax", and "Parent Tax Benefit" as well as any terms used herein to define such terms shall be interpreted to refer to the applicable combined, consolidated or unitary tax return for which tax is being allocated. Section Twelve: Penalties & Interest (a) Any penalties incurred by the Parent relating to filing the Consolidated Return shall be specifically assigned to the member(s) of the Parent Group to whom such penalty is directly attributable (and shall become part of the Subsidiary's allocable share of the Consolidated Tax liability), provided however, that penalties shall not be specifically assigned to any particular Subsidiary if the imposition of such penalty is not directly attributable to the acts, errors, or omissions of the Subsidiary. Penalties not specifically assigned pursuant to the previous sentence shall be allocated among the Parent and Subsidiaries on a pro rata basis in accordance with their Separate Return Tax liabilities. (b) Any interest incurred by the Parent related to filing the Consolidated Return shall be specifically allocated to the Subsidiary to whom such interest is directly attributable (and shall become part of the Subsidiary's allocable share of the Consolidated Tax), provided however, that interest shall not be specifically allocated to any Subsidiary if the imposition of such interest is not directly attributable to the acts, errors, or omissions of the Subsidiary. Interest not specifically allocated pursuant to the previous sentence shall be allocated among the Parent and the Subsidiaries on a pro rata basis in accordance with their separate tax liabilities. Section Thirteen: Changes in Parties (a) New direct or indirect subsidiaries, affiliates and associates of Parent, which may come into existence after the effective date of this Agreement, may become additional "Subsidiaries," and become subject to this Agreement. In addition, entities which are, as of the effective date of this Agreement, direct or indirect subsidiaries, affiliates and associates of Parent, may thereafter leave the holding company system, in which case they will no longer be subject to this Agreement for tax years after their departure. (b) The addition of a new direct or indirect subsidiary, affiliate or associate company is intended to be evidenced by the signing of a written joinder to this Agreement but, notwithstanding the failure of a new subsidiary, affiliate or associate company to sign a written joinder, the new subsidiary, affiliate or associate company shall be conclusively deemed to have accepted and agreed to the terms of this Agreement by reason of its inclusion in Parent's consolidated Federal income tax return and/or any state and local income tax returns filed on a combined, unitary, consolidated or similar basis with other members of the Parent group. Section Fourteen: Miscellaneous Provisions (a) This Agreement contains the entire understanding of the parties with respect to the subject matter of this Agreement. No alteration, amendment, or 129

modification of any of the terms of this Agreement shall be valid unless made by an instrument signed in writing by an authorized officer of each party. (b) This Agreement has been made in and shall be construed and enforced in accordance with the laws of the Commonwealth of Pennsylvania from time to time in effect. (c) Notwithstanding any provision of this Agreement to the contrary, income tax shall be allocated among the parties in a manner consistent with Title 17, Section 250.45(c)(4) of the Code of Federal Regulations. Under no circumstances shall the amount of tax liability allocated to or paid by a Subsidiary under this Agreement during the Computation Period exceed the aggregate Separate Return Tax for the Subsidiary for the Computation Period determined as if the Subsidiary had filed separate returns. (d) This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. (e) All notices and other communications hereunder shall be deemed to have been duly given if delivered by hand or mailed by certified or registered mail, postage prepaid: (i) if to Parent: 10 S.
