Exelon Generation Company, LLC Form S-4, April 4, 2002, Indenture dated June 1,
2001 between registrant and First Union National Bank (now Wachovia Bank,
National Association)(Registration Statement No. 333-85496, Form S-4, Exhibit
4.1).

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.

D. TAX ALLOCATION AGREEMENT PURSUANT TO RULE 45(c)

                              TAX SHARING AGREEMENT

        THIS AGREEMENT, dated as of the 1st day of January, 2003, by and between
Exelon Corporation, a Pennsylvania corporation ("Parent"), Exelon Energy
Delivery Company, LLC, a Delaware limited liability company, Exelon Ventures
Company LLC, a Delaware limited liability company, Unicom Investment, Inc., an
Illinois corporation, and Exelon Business Services Company, a Pennsylvania
corporation and each of PECO Energy Company, Commonwealth Edison Corporation,
Exelon Generation Company, LLC, Exelon Enterprises Company, LLC and the
companies listed on Schedule A attached hereto (each a "Subsidiary").

                               W I T N E S S E T H

        WHEREAS, Parent is the common parent corporation of an affiliated group
of corporations within the meaning of Section 1504(a) of the Internal Revenue
Code of 1986, as amended (the "Code");

        WHEREAS, the Subsidiaries are each members of that affiliated group or
otherwise have taxable income included directly on the tax return of a member of
the group (i.e. such Subsidiary is treated as a disregarded entity for tax
purposes);

        WHEREAS, the members of the affiliated group anticipate filing a
consolidated federal income tax return and combined, consolidated or unitary
state income tax returns where required or where elections to so file have or
will be made;

        WHEREAS, Parent and the Subsidiaries wish to agree upon a fair and
equitable method for determining the share of the group's consolidated federal
income tax burdens and benefits properly attributable to each Subsidiary; and

        WHEREAS, Parent and the Subsidiaries wish to agree upon a fair and
equitable method for determining the share of any state taxes to be borne by any
members of the Parent Group who file state and local income tax returns (or
other state returns) on a combined, unitary, consolidated or similar basis.

        NOW, THEREFORE, in consideration of the premises and of the covenants
and agreements set forth below, the parties, intending to be legally bound,
agree as follows:

         Section One:  Definitions

         For purposes of this Agreement, the terms set forth below shall have
the following meanings:

         (a) Affiliated Group: The affiliated group of corporations (within the
         meaning Section 1504(a) of the Code) of which Parent is the common
         parent.

         (b) Code: The Internal Revenue Code of 1986, as amended.




                                      124


         (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.
