EXELON CORPORATION AND SUBSIDIARY COMPANIES
COMMONWEALTH EDISON COMPANY AND SUBSIDIARY COMPANIES
PECO ENERGY COMPANY AND SUBSIDIARY COMPANIES
EXELON GENERATION COMPANY, LLC AND SUBSIDIARY COMPANIES
COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Dollars in millions, except per share data, unless otherwise noted)

1. BASIS OF PRESENTATION (Exelon, ComEd, PECO and Generation)
The accompanying consolidated financial statements as of June 30, 2002
and for the three and six months then ended are unaudited, but include all
adjustments that Exelon Corporation (Exelon), Commonwealth Edison Company
(ComEd), PECO Energy Company (PECO) and Exelon Generation Company, LLC
(Generation) consider necessary for a fair presentation of their respective
financial statements. All adjustments are of a normal, recurring nature, except
as otherwise disclosed. The December 31, 2001 consolidated balance sheet data
were derived from audited financial statements but do not include all
disclosures required by generally accepted accounting principles. Certain
prior-year amounts have been reclassified for comparative purposes. These
reclassifications had no effect on net income or shareholders' or member's
equity. These notes should be read in conjunction with the Notes to Consolidated
Financial Statements of Exelon, ComEd and PECO included in or incorporated by
reference in Item 8 of their Annual Report on Form 10-K for the year ended
December 31, 2001 and the Notes to Consolidated Financial Statements in
Generation's Form S-4 registration statement declared effective on April 24,
2002 by the Securities and Exchange Commission (SEC), (Generation's Form S-4).
See ITEM 6. Exhibits and Reports on Form 8-K.


2. ADOPTION OF NEW ACCOUNTING PRINCIPLES (Exelon, ComEd, PECO and Generation)
SFAS No. 141 and SFAS No. 142
In 2001, the Financial Accounting Standard Board (FASB) issued
Statement of Accounting Standard (SFAS) No. 141, "Business Combinations" (SFAS
No. 141), which requires that all business combinations be accounted for under
the purchase method of accounting and establishes criteria for the separate
recognition of intangible assets acquired in business combinations. SFAS No. 141
is effective for business combinations initiated after June 30, 2001. In
addition, SFAS No. 141 requires that unamortized negative goodwill related to
pre-July 1, 2001 purchases be recognized as a change in accounting principle
concurrent with the adoption of SFAS No. 142, "Goodwill and Other Intangible
Assets" (SFAS No. 142). At December 31, 2001, AmerGen Energy Company, LLC
(AmerGen), an equity-method investee of Generation, had $43 million of negative
goodwill, net of accumulated amortization, recorded on its balance sheet. Upon
AmerGen's adoption of SFAS No. 141 in January 2002, Generation recognized its
proportionate share of income of $22 million ($13 million, net of income taxes)
as a cumulative effect of a change in accounting principle.

Exelon, ComEd, PECO and Generation adopted SFAS No. 142 as of January
1, 2002. SFAS No. 142 establishes new accounting and reporting standards for
goodwill and intangible assets. Other than goodwill, Exelon does not have
significant other intangible assets recorded on its consolidated balance sheets.
Under SFAS No. 142, goodwill is no longer subject to amortization, however,


21


goodwill is subject to an assessment for impairment using a two-step fair value
based test, the first step of which must be performed at least annually, or more
frequently if events or circumstances indicate that goodwill might be impaired.
The first step compares the fair value of a reporting unit to its carrying
amount, including goodwill. If the carrying amount of the reporting unit exceeds
its fair value, the second step is performed. The second step compares the
carrying amount of the goodwill to the fair value of the goodwill. If the fair
value of goodwill is less than the carrying amount, an impairment loss is
reported as a reduction to goodwill and a charge to operating expense, except at
the transition date, when the loss is reflected as a cumulative effect of a
change in accounting principle.

As of December 31, 2001, Exelon's Consolidated Balance Sheets reflected
approximately $5.3 billion in goodwill net of accumulated amortization,
including $4.9 billion of net goodwill related to the October 20, 2000 merger of
Unicom Corporation (Unicom), the former parent company of ComEd, and PECO
(Merger) recorded on ComEd's Consolidated Balance Sheets, with the remainder
related to acquisitions by Exelon Enterprises Company, LLC (Enterprises). The
first step of the transitional impairment analysis indicated that ComEd's
goodwill was not impaired but that an impairment did exist with respect to
goodwill recorded in Enterprises' reporting units. Exelon's infrastructure
services business (InfraSource), the energy services business (Exelon Services)
and the competitive retail energy sales business (Exelon Energy) were determined
to be those reporting units of Enterprises that had goodwill allocated to them.
The second step of the analysis, which compared the fair value of each of
Enterprises' reporting units' goodwill to the carrying value at December 31,
2001, indicated a total goodwill impairment of $357 million ($243 million, net
of income taxes and minority interest). The fair value of the Enterprises'
reporting units was determined using discounted cash flow models reflecting the
expected range of future cash flow outcomes related to each of the Enterprises
reporting units over the life of the model. These cash flows were discounted to
2002 using a risk-adjusted discount rate. The impairment was recorded as a
cumulative effect of a change in accounting principle in the first quarter of
2002.

The changes in the carrying amount of goodwill by reportable segment
(see Note 6 for further discussion of reportable segments) for the six months
ended June 30, 2002 are as follows:



Energy
Delivery Enterprises Total
- ---------------------------------------------------------------------------------------------------------------------

Balance as of January 1, 2002 $ 4,902 $ 433 $ 5,335
Impairment losses -- (357) (357)
Settlement of pre-merger income tax contingency (7) -- (7)
- ---------------------------------------------------------------------------------------------------------------------
Balance as of June 30, 2002 $ 4,895 $ 76 $ 4,971
- ---------------------------------------------------------------------------------------------------------------------


The June 30, 2002, Energy Delivery goodwill relates to ComEd and the
remaining Enterprises goodwill relates to the InfraSource and Exelon Services
reporting units. Consistent with SFAS No. 142, the remaining goodwill will be
reviewed for impairment on an annual basis or more frequently if significant
events occur that could indicate an impairment exists.



22


The components of the net transitional impairment loss recognized in
the first quarter of 2002 as a cumulative effect of a change in accounting
principle are as follows:



Exelon
- -----------------------------------------------------------------------------------------------------

Enterprises goodwill impairment (net of income taxes of $103 million) $ (254)
Minority interest (net of income taxes of $4 million) 11
Elimination of AmerGen negative goodwill (net of income taxes of $9 million) 13
- -----------------------------------------------------------------------------------------------------
Total cumulative effect of a change in accounting principle $ (230)
- -----------------------------------------------------------------------------------------------------

Generation
- -----------------------------------------------------------------------------------------------------
Elimination of AmerGen negative goodwill (net of income taxes of $9 million)
recorded as cumulative effect of a change in accounting principle $ 13
- -----------------------------------------------------------------------------------------------------













23


The following tables set forth Exelon's net income and earnings per
common share and ComEd's net income for the three and six months ended June 30,
2002 and 2001, respectively, adjusted to exclude 2001 amortization expense

Generation
The cessation of the amortization of negative goodwill of AmerGen on
January 1, 2002 did not have a material impact on Generation's reported net
income for the three or six months ended June 30, 2002.


24


EITF Issue 02-3
Exelon and Generation early adopted the provision of Emerging Issues
Task Force (EITF) Issue 02-3 "Accounting for Contracts Involved in Energy
Trading and Risk Management Activities" (EITF 02-3) issued by the FASB EITF in
June 2002 that requires revenues and energy costs related to energy trading
contracts to be presented on a net basis in the income statement. Prior to the
second quarter of 2002, revenues from trading activity were presented in Revenue
and the energy costs related to energy trading were presented as either
Purchased Power or Fuel expense on Exelon and Generation's Consolidated
Statements of Income. For comparative purposes, energy costs related to energy
trading have been reclassified in prior periods to revenue to conform with the
net basis of presentation required by EITF 02-3. For the three and six months
ended June 30, 2001, $30 million of purchased power expense and $5 million of
fuel expense was reclassified and reflected as a reduction to revenue. The three
months ended March 31, 2002 included $504 million of purchased power expense and
$9 million of fuel expense that has been reclassified and reflected as a
reduction to revenue in the six months ended June 30, 2002.

SFAS No. 144
In August 2001, the FASB issued SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets" (SFAS No. 144). Exelon, ComEd, PECO
and Generation adopted SFAS No. 144 on January 1, 2002. SFAS No. 144 establishes
accounting and reporting standards for both the impairment and disposal of
long-lived assets. SFAS No. 144 is effective for fiscal years beginning after
December 15, 2001 and its provisions are generally applied prospectively. The
adoption of this statement had no effect on Exelon's reported financial
positions, results of operations or cash flows.

SFAS No. 133
SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (SFAS No. 133) applies to all derivative instruments and requires
that such instruments be recorded on the balance sheet either as an asset or a
liability measured at their fair value through earnings, with special accounting
permitted for certain qualifying hedges. On January 1, 2001, Exelon, ComEd,
PECO, and Generation adopted SFAS No. 133. Generation recognized a non-cash gain
of $12 million, net of income taxes, in earnings and deferred a non-cash gain of
$4 million, net of income taxes, in accumulated other comprehensive income and
PECO deferred a non-cash gain of $40 million, net of income taxes, in
accumulated other comprehensive income.


3. ACQUISITIONS AND DISPOSITIONS (Exelon and Generation)
Acquisition of Generating Plants from TXU
On April 25, 2002, Generation acquired two natural-gas and oil-fired plants from
TXU Corp. (TXU) for an aggregate purchase price of $443 million. The purchase
included the 893-megawatt Mountain Creek Steam Electric Station in Dallas and
the 1,441-megawatt Handley Steam Electric Station in Fort Worth. The transaction
included a power purchase agreement for TXU to purchase power during the months
of May through September from 2002 through 2006. During the periods covered by
the power purchase agreement, TXU will make fixed capacity payments and will
provide fuel to Exelon in return for exclusive rights to the energy and capacity
of the generation plants. Substantially all of the purchase price has been
allocated to property, plant, and equipment pending final valuation of plant
assets.



25



Sale of AT&T Wireless
On April 1, 2002, Enterprises sold its 49% interest in AT&T Wireless
PCS of Philadelphia, LLC to a subsidiary of AT&T Wireless Services for $285
million in cash. Enterprises recorded an after-tax gain of $116 million in
other, net on the $84 million investment, which was reflected in Deferred Debits
and Other Assets on Exelon's Consolidated Balance Sheets.

Sithe New England Holdings, LLC Acquisition
On June 26, 2002, Generation agreed to purchase Sithe New England
Holdings, LLC, (Sithe New England) a subsidiary of Sithe Energies Inc. (Sithe),
and related power marketing operations in exchange for a $543 million note plus
the assumption of non-recourse debt, estimated to be approximately $1.2 billion
at the transaction closing date. The parties are seeking Federal Energy
Regulatory Commission (FERC) and other required approvals of the purchase by
October 31, 2002. Exelon has negotiated closing conditions that allow Exelon to
terminate the purchase if the conditions are not satisfied. If approved, and if
the closing conditions are satisfied, the transaction could be completed in
November 2002.

The purchase involves approximately 4,471 MWs of generation capacity,
consisting of 2,050 MWs in operation and 2,421 MWs under construction, which
will increase Generation's net assets by approximately $1.7 billion when the
transaction closes. Sithe New England's generation facilities are located
primarily in Massachusetts, but are also located in Maine.

Generation is a 49.9% owner of Sithe and accounts for the investment as
an unconsolidated equity investment. The Sithe New England purchase will not
affect the accounting for Sithe as an equity investment. Additionally,
Generation is subject to a Put and Call Agreement (PCA) that gives Generation
the right to purchase (Call) the remaining 50.1% of Sithe, and gives the other
Sithe shareholders the right to sell (Put) their interest to Generation. If the
Put option is exercised, Generation has the obligation to complete the purchase.
The PCA provides that the Put and Call options become exercisable as of December
18, 2002. The Sithe New England purchase is a separate transaction from the PCA
that is intended to enable Generation to acquire only the Sithe assets that fit
Generation's strategy, accelerate the realization of synergies, and reduce the
amount of debt needed to finance the transaction.

See ITEM 2. Management's Discussion and Analysis of Financial Condition
and Results of Operations - Exelon Corporation - for further discussion of the
PCA.


4. REGULATORY ISSUES (Exelon, ComEd and PECO)
On April 1, 2002, the Illinois Commerce Commission (ICC) issued an
interim order in ComEd's Delivery Services Rate Case. The interim order is
subject to an audit of test year expenditures that is anticipated to be
completed by the end of 2002 with a final order to be issued in 2003. The order
sets new delivery rates for residential customers choosing a new retail electric
supplier. The new rates became effective May 1, 2002 when residential customers
were eligible to choose their supplier of electricity. Traditional bundled rates
paid by customers that retain ComEd as their electricity supplier are not
affected by this order. Bundled rates will remain frozen through 2006, as a
result of the June 6, 2002 amendments to the Illinois


26


Restructuring Act that extended the freeze on bundled rates for an additional
two years. Delivery service rates for non-residential customers are not affected
by the order. The potential revenue impact of the interim order is not expected
to be material in 2002.

As permitted by the Pennsylvania Electric Competition Act, the
Pennsylvania Department of Revenue has calculated a 2002 Revenue Neutral
Reconciliation (RNR) adjustment to the gross receipts tax rate in order to
neutralize the impact of electric restructuring on its tax revenues. In January
2002, the Pennsylvania Public Utility Commission (PUC) approved the RNR
adjustment to the gross receipts tax rate collected from customers. Effective
January 1, 2002, PECO implemented the change in the gross receipts tax rate. The
RNR adjustment is under appeal. The RNR adjustment increases the gross receipts
tax rate, which will increase PECO's annual revenues and tax obligations by
approximately $50 million in 2002.


5. EARNINGS PER SHARE (Exelon)
Diluted earnings per share are calculated by dividing net income by the
weighted average number of shares of common stock outstanding, including shares
issuable upon exercise of stock options outstanding under Exelon's stock option
plans considered to be common stock equivalents. The following table shows the
effect of these stock options on the weighted average number of shares
outstanding used in calculating diluted earnings per share (in millions):


Three Months Ended June 30, Six Months Ended June 30,
--------------------------- -------------------------
2002 2001 2002 2001
- ----------------------------------------------------------------------------------------------------------------------

Average common shares outstanding 322 321 322 320
Assumed exercise of stock options 2 3 2 3
- ----------------------------------------------------------------------------------------------------------------------
Average diluted common shares outstanding 324 324 324 323
- ----------------------------------------------------------------------------------------------------------------------


Stock options not included in average common shares used in calculating
diluted earnings per share due to their antidilutive effect were three million
for the three and six months ended June 30, 2002 and one million for the three
and six months ended June 30, 2001.

6. SEGMENT INFORMATION (Exelon)
Exelon operates in three business segments: energy delivery, generation
and enterprises. Energy delivery consists of the operations of ComEd and PECO.
Beginning in 2002, Exelon evaluates the performance of its business segments on
the basis of net income. Exelon's segment information for the three months and
six months ended June 30, 2002 as compared to the same periods in 2001 and at
June 30, 2002 and December 31, 2001 are as follows:

7. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES (Exelon, ComEd, PECO and
Generation)
During the three and six months ended June 30, 2002 and 2001, Exelon
recorded net gains/(losses) in other comprehensive income relating to
mark-to-market (MTM) adjustments of contracts designated as cash flow hedges as
follows:



ComEd PECO Generation Enterprises Exelon
- ---------------------------------------------------------------------------------------------------------------------

Six months ended June 30, 2001 -- 8 (62) 2 (52)
- ---------------------------------------------------------------------------------------------------------------------


During the three months ended June 30, 2002 and 2001, and the six
months ended June 30, 2002 and 2001, Generation recognized net MTM gains on
non-trading energy derivative contracts not designated as cash flow hedges, in
operating revenues as follows:

- ---------------------------------------------------------------------------------------------------------------------

Three months ended June 30, $ 4 $ 5
Six months ended June 30, 10 22
- ---------------------------------------------------------------------------------------------------------------------


During the three months ended June 30, 2002 and 2001 and the six months
ended June 30, 2002 and 2001, no amounts were reclassified from accumulated
other comprehensive income into earnings as a result of forecasted energy
commodity transactions no longer being probable.

During the three months ended June 30, 2002 and 2001, and the six
months ended June 30, 2002 and 2001, Generation recognized net MTM losses on
energy trading contracts, in operating revenues as follows:

During the three months ended June 30, 2002 and 2001 and the six months
ended June 30, 2002 and 2001, PECO reclassified other income in the Consolidated
Statements of Income and Comprehensive Income, as a result of the discontinuance
of cash flow hedges related to certain forecasted financing transactions that
were no longer probable of occurring as follows:

As of June 30, 2002, deferred net gains on derivative instruments
accumulated in other comprehensive income are expected to be reclassified to
earnings during the next twelve months are as follows:



ComEd PECO Generation Enterprises Exelon
- ---------------------------------------------------------------------------------------------------------------------

Gains Expected to be Reclassified $ 1 $ 15 $ -- $ 2 $ 18
- ---------------------------------------------------------------------------------------------------------------------


Amounts in accumulated other comprehensive income related to interest
rate cash flow hedges are reclassified into earnings when the forecasted
interest payment occurs. Amounts in accumulated other comprehensive income
related to energy commodity cash flows are reclassified into earnings when the
forecasted purchase or sale of the energy commodity occurs.

Generation classifies investments in the trust accounts for
decommissioning nuclear plants as available-for-sale. The following tables show
the fair values, gross unrealized gains and losses and amortized cost bases for
the securities held in these trust accounts.



June 30, 2002

- ---------------------------------------------------------------------------------------------------------------------


Unrealized gains and losses are recognized in Accumulated Depreciation
and Accumulated Other Comprehensive Income in Generation's Consolidated Balance
Sheet.

For the three months ended June 30, 2002, proceeds from the sale of
decommissioning trust investments and gross realized gains and losses on those
sales were $309 million, $13 million and $24 million, respectively. For the six
months ended June 30, 2002, proceeds from the sale of decommissioning trust
investments and gross realized gains and losses on those sales were $889
million, $31 million and $56 million, respectively.

Net realized losses of $4 million were recognized in Accumulated
Depreciation in Generation's Consolidated Balance Sheets at June 30, 2002 and
$21 million of net realized losses were recognized in Other Income and
Deductions in Generation's Consolidated Statements of Income and Comprehensive
Income for the six months ended June 30, 2002. The available-for-sale securities
held at June 30, 2002 have an average maturity of eight to ten years. The cost
of these securities was determined on the basis of specific identification.

8. COMMITMENTS AND CONTINGENCIES (Exelon, ComEd, PECO and Generation)
For information regarding capital commitments, nuclear decommissioning
and spent fuel storage, see the Commitments and Contingencies Note in the
Consolidated Financial Statements of Exelon, ComEd and PECO for the year ended
December 31, 2001 and Generation's S-4 dated April 24, 2002.

Environmental Liabilities
Exelon has identified 72 sites where former manufactured gas plant
(MGP) activities have or may have resulted in actual site contamination. As of
June 30, 2002, Exelon had accrued $139 million for environmental investigation
and remediation costs that currently can be reasonably estimated, including $115
million for MGP investigation and remediation.

ComEd had accrued $96 million (discounted) as of June 30, 2002, for
environmental investigation and remediation costs that currently can be
reasonably estimated. This reserve included $90 million for MGP investigation
and remediation. ComEd is currently experiencing delays in the ongoing
remediation of an MGP site in Oak Park, Illinois, and is evaluating the impact
of those delays on the cost to complete the project. The impact of the delays is
currently uncertain, but could increase the environmental reserve in the future.

PECO had accrued $34 million (undiscounted) as of June 30, 2002, for
environmental investigation and remediation costs that currently can be
reasonably estimated, including $25 million for MGP investigation and
remediation.

Generation had accrued $9 million (undiscounted) as of June 30, 2002,
for environmental investigation and remediation cost, none of which relates to
MGP investigation and remediation.

Exelon, ComEd, PECO and Generation cannot predict the extent to which
they will incur other significant liabilities for additional investigation and
remediation costs at these or additional sites identified by environmental
agencies or others, or whether such costs may be recoverable from third parties.





31


Energy Commitments
Exelon and Generation had long-term commitments relating to the net
purchase and sale of energy, capacity and transmission rights from unaffiliated
utilities, including Midwest Generation LLC (Midwest Generation), and others,
including AmerGen, as expressed in the following table:



Power Only Purchases from

- ---------------------------------------------------------------------------------------------------------------------
Total $ 7,046 $ 4,811 $ 3,174 $ 2,863 $ 354
- ---------------------------------------------------------------------------------------------------------------------

(1) Net Capacity Purchases includes Midwest Generation commitments as of July
1, 2002. On July 1, 2002, Generation notified Midwest Generation of the
exercise of its call options under the existing Coal Generation Purchase
Power Agreement. Generation exercised options on 1,265 MWs of capacity and
did not exercise options on 2,684 MWs of capacity. In 2003, Generation will
take 1,696 MWs of non-option capacity and 1,265 MWs of option capacity
under the existing contract. Net Capacity Purchases also includes capacity
sales to TXU under the purchase power agreement entered into in connection
with the purchase of two generating plants in April 2002, which states that
TXU will purchase the plant output from May through September from 2002
through 2006. The combined capacity of the two plants is 2,334 MWs.



In connection with the 2001 corporate restructuring, ComEd entered into
a purchase power agreement (PPA) with Generation. Under the terms of the PPA,
Generation has agreed to supply all of ComEd's load requirements through 2004.
Prices for this energy vary depending upon the time of day and month of
delivery. During 2005 and 2006, ComEd's PPA is a partial requirements agreement
under which ComEd will purchase all of its required energy and capacity from
Generation, up to the available capacity of the nuclear generating plants
formerly owned by ComEd and transferred to Generation. Under the terms of the
PPA, Generation is responsible for obtaining any required transmission service.
The PPA also specifies that prior to 2005, ComEd and Generation will jointly
determine and agree on a market-based price for energy delivered under the PPA
for 2005 and 2006. In the event that the parties cannot agree to market-based
prices for 2005 and 2006 prior to July 1, 2004, ComEd has the option of
terminating the PPA effective December 31, 2004. ComEd will obtain any
additional supply required from market sources in 2005 and 2006, and subsequent
to 2006, will obtain all of its supply from market sources, which could include
Generation.

In connection with the 2001 corporate restructuring, PECO entered into
a PPA with Generation. Under the terms of the PPA, PECO obtains substantially
all of its electric supply from Generation through 2010. Also, under the
restructuring, PECO assigned its rights and obligations under various PPAs and
fuel supply agreements to Generation. Generation supplies power to PECO from the
transferred generation assets, assigned PPAs and other market sources.


32


Under terms of the 2001 corporate restructuring, ComEd remits to
Generation any amounts collected from customers for nuclear decommissioning.
Under an agreement effective September 2001, PECO remits to Generation any
amounts collected from customers for nuclear decommissioning.

Litigation
Exelon
Securities Litigation. Between May 8 and June 14, 2002, a total of six
nearly identical class action lawsuits were filed in the Federal District Court
in Chicago asserting securities claims on behalf of Exelon investors during
April to September 2001. The complaints allege that Exelon violated Federal
securities laws by issuing a series of materially false and misleading
statements relating to its 2001 earnings expectations during the Class Period.
On May 30 and July 2, 2002, the Court granted Exelon's agreed-upon motions to
consolidate the pending cases into one lawsuit, and stayed discovery
indefinitely. A lead plaintiff has not been selected. Exelon believes the
lawsuit is without merit and is vigorously contesting this matter.

ComEd
Chicago Franchise. In March 1999, ComEd reached a settlement agreement
with the City of Chicago (Chicago) to end the arbitration proceeding between
ComEd and Chicago regarding the January 1, 1992 franchise agreement. As part of
the settlement agreement, ComEd and Chicago agreed to a revised combination of
ongoing work under the franchise agreement and new initiatives that will result
in defined transmission and distribution expenditures by ComEd to improve
electric services in Chicago. The settlement agreement provides that ComEd would
be subject to liquidated damages if the projects are not completed by various
dates, unless it was prevented from doing so by events beyond its reasonable
control. In addition, ComEd and Chicago established an Energy Reliability and
Capacity Account, into which ComEd deposited $25 million during each of the
years 1999 through 2001 and has conditionally agreed to deposit $25 million at
the end of 2002, to help ensure an adequate and reliable electric supply for
Chicago.

FERC Municipal Request for Refund. Three of ComEd's wholesale municipal
customers filed a complaint and request for refund with the FERC alleging that
ComEd failed to properly adjust its rates, as provided for under the terms of
the electric service contracts with the municipal customers and to track certain
refunds made to ComEd's retail customers in the years 1992 through 1994. In the
third quarter of 1998, FERC granted the complaint and directed that refunds be
made, with interest. ComEd filed a request for rehearing. On April 30, 2001,
FERC issued an order granting rehearing in which it determined that its 1998
order had been erroneous and that no refunds were due from ComEd to the
municipal customers. On June 29, 2001, FERC denied the customers' requests for
rehearing of the order granting rehearing. In August 2001, each of the three
wholesale municipal customers appealed the April 30, 2001 FERC order to the
Federal circuit court, which consolidated the appeals for the purposes of
briefing and decision. In November 2001, the court suspended briefing pending
court-initiated settlement discussions.

Retail Rate Law. In 1996, several developers of non-utility generating
facilities filed litigation against various Illinois officials claiming that the
enforcement against those facilities of an amendment to Illinois law removing
the entitlement of those facilities to state-subsidized


33


payments for electricity sold to ComEd after March 15, 1996 violated their
rights under the Federal and state constitutions. The developers also filed suit
against ComEd for a declaratory judgment that their rights under their contracts
with ComEd were not affected by the amendment. On August 4, 1999, the Illinois
Appellate Court held that the developers' claims against the state were
premature, and the Illinois Supreme Court denied leave to appeal that ruling.
Developers of both facilities have since filed amended complaints repeating
their allegations that ComEd breached the contracts in question and requesting
damages for such breach reflecting the state-subsidized rate to which the
developers claim they were entitled under their contracts. These matters are in
the discovery phase. Certain of the plaintiffs have produced an expert report
claiming approximately $175 million in damages, a quantification ComEd
vigorously disputes. Virtually all parties have filed motions for summary
judgment. ComEd is contesting each case and has filed its motion for summary
judgment arguing that, as a matter of law, it did not breach any of the
contracts.

Service Interruptions. In August 1999, three class action lawsuits were
filed against ComEd, and subsequently consolidated, in the Circuit Court of Cook
County, Illinois seeking damages for personal injuries, property damage and
economic losses related to a series of service interruptions that occurred in
the summer of 1999. The combined effect of these interruptions resulted in over
168,000 customers losing service for more than four hours. Conditional class
certification was approved by the court for the sole purpose of exploring
settlement talks. ComEd filed a motion to dismiss the complaints. On April 24,
2001, the court dismissed four of the five counts of the consolidated complaint
without prejudice and the sole remaining count was dismissed in part. On June 1,
2001, the plaintiffs filed a second amended consolidated complaint and ComEd has
filed an answer. A portion of any settlement or verdict may be covered by
insurance; discussions with the carrier are ongoing.

Enron. As a result of Enron Corp.'s bankruptcy proceeding, ComEd has
potential monetary exposure for 366 of its customer accounts that were served by
Enron Energy Services (EES) as a billing agent. EES has rejected its contracts
with these accounts, with the exception of approximately 100 accounts for which
EES retains its billing agency. ComEd is working to ensure that customers know
what amounts are owed to ComEd on accounts for which EES has been removed as
billing agent, and has obtained updated billing addresses for these accounts.
With regard to the accounts for which EES retains its billing agency, ComEd's
total amount outstanding is not material. Because that amount is owed to ComEd
by individual customers, it is not part of the bankrupt Enron's estate. The ICC
has rescinded EES's authority to act as an alternative retail energy supplier in
Illinois. However, EES never served as a supplier, as opposed to a billing
agent, to any of ComEd's retail accounts.

ComEd and Generation
Godley Park District Litigation. On April 18, 2001, the Godley Park
District filed suit in Will County Circuit Court against ComEd and Generation
alleging that oil spills at Braidwood Station have contaminated the Park
District's water supply. The complaint sought actual damages, punitive damages
of $100 million and statutory penalties. The court dismissed all counts seeking
punitive damages and statutory penalties, and the plaintiff has filed an amended
complaint before the court. The amended complaint added counts under the
Illinois Public Utility Act (PUA), which provides for statutory penalties and
allows recovery of attorneys fees. On


34


April 20, 2002, the Court denied ComEd and Generation's motion to dismiss the
additional counts under the PUA. ComEd and Generation are contesting the
liability and damages sought by the plaintiff.

Generation
Cotter Corporation Litigation. During 1989 and 1991, actions were
brought in Federal and state courts in Colorado against ComEd and its
subsidiary, Cotter Corporation (Cotter), seeking unspecified damages and
injunctive relief based on allegations that Cotter permitted radioactive and
other hazardous material to be released from its mill into areas owned or
occupied by the plaintiffs, resulting in property damage and potential adverse
health effects. In 1994, a Federal jury returned nominal dollar verdicts against
Cotter on eight plaintiffs' claims in the 1989 cases, which verdicts were upheld
on appeal. The remaining claims in the 1989 actions were settled or dismissed.
In 1998, a jury verdict was rendered against Cotter in favor of 14 of the
plaintiffs in the 1991 cases, totaling approximately $6 million in compensatory
and punitive damages, interest and medical monitoring. On appeal, the Tenth
Circuit Court of Appeals reversed the jury verdict, and remanded the case for
new trial. These plaintiffs' cases were consolidated with the remaining 26
plaintiffs' cases, which had not been tried. The consolidated trial was
completed on June 28, 2001. The jury returned a verdict against Cotter and
awarded $16.3 million in various damages. On November 20, 2001, the District
Court entered an amended final judgment that included an award of both
pre-judgment and post-judgment interests, costs, and medical monitoring expenses
that total $43.3 million. This matter is being appealed by Cotter in the Tenth
Circuit Court of Appeals. Cotter will vigorously contest the award.

In November 2000, another trial involving a separate sub-group of 13
plaintiffs, seeking $19 million in damages plus interest was completed in
federal district court in Denver. The jury awarded nominal damages of $42,500 to
11 of 13 plaintiffs, but awarded no damages for any personal injury or health
claims, other than requiring Cotter to perform periodic medical monitoring at
minimal cost. Cotter and the plaintiffs both appealed the verdict to the Tenth
Circuit Court of Appeals.

On February 18, 2000, ComEd sold Cotter to an unaffiliated third party.
As part of the sale, ComEd agreed to indemnify Cotter for any liability incurred
by Cotter as a result of these actions, as well as any liability arising in
connection with the West Lake Landfill discussed in the next paragraph. In
connection with Exelon's 2001 corporate restructuring, the responsibility to
indemnify Cotter for any liability related to these matters was transferred by
ComEd to Generation.

The United States Environmental Protection Agency (EPA) has advised
Cotter that it is potentially liable in connection with radiological
contamination at a site known as the West Lake Landfill in Missouri. Cotter is
alleged to have disposed of approximately 39,000 tons of soils mixed with 8,700
tons of leached barium sulfate at the site. Cotter, along with three other
companies identified by the EPA as potentially responsible parties (PRPs), is
reviewing a draft feasibility study that recommends capping the site. The PRPs
are also engaged in discussions with the State of Missouri and the EPA. The
estimated costs of remediation for the site are $10 to $15 million. Once a final
feasibility study is complete and a remedy selected, it is expected


35


that the PRPs will agree on an allocation of responsibility for the costs. Until
an agreement is reached, Exelon cannot predict its share of the costs.

Real Estate Tax Appeals. Generation is involved in tax appeals
regarding a number of its nuclear facilities, Limerick Generating Station
(Montgomery County, PA), Peach Bottom Atomic Power Station (York County, PA),
Quad Cities Station (Rock Island County, IL), and one of its fossil facilities,
Eddystone (Delaware County, PA). Generation is also involved in the tax appeal
for Three Mile Island (Dauphin County, PA) through AmerGen. Generation does not
believe the outcome of these matters will have a material adverse effect on
Generation's results of operations or financial condition.

General
Exelon, ComEd, PECO and Generation are involved in various other
litigation matters. The ultimate outcome of such matters, as well as the matters
discussed above, while uncertain, are not expected to have a material adverse
effect on its respective financial condition or results of operations.


9. MERGER-RELATED COSTS (Exelon, ComEd, PECO and Generation)
In association with the Merger, Exelon recorded certain reserves for
restructuring costs. The reserves associated with PECO were charged to expense,
while the reserves associated with Unicom were recorded as part of the
application of purchase accounting and did not affect results of operations.

Merger-related costs charged to expense in 2000 were $276 million,
consisting of $124 million for PECO employee costs and $152 million of direct
incremental costs. Direct incremental costs represent expenses directly
associated with completing the Merger, including professional fees, regulatory
approval and settlement costs, and settlement of compensation arrangements.
Employee costs represent estimated severance costs and pension and
postretirement benefits provided under Exelon's merger separation plans for
eligible employees who are expected to be involuntarily terminated before
December 2002 due to integration activities of the merged companies.

The purchase price allocation as of December 31, 2000 included a
liability of $307 million for Unicom employee costs and liabilities of
approximately $39 million for estimated costs of exiting various business
activities of former Unicom activities that were not compatible with the
strategic business direction of Exelon.


36


During 2001, Exelon finalized its plans for consolidation of functions,
including negotiation of an agreement with the International Brotherhood of
Electrical Workers Local 15 regarding severance benefits to union employees and
recorded adjustments to the purchase price allocation as follows:



Original 2001 Adjusted
Estimate Adjustments Liabilities

Additional employee severance costs of $48 million primarily related to
PECO employees were charged to expense in 2001. Exelon anticipates that a total
of $281 million of employee costs will be funded from pension and postretirement
benefit plans.

As part of the January 2001 corporate restructuring, portions of the
employee severance and restructuring reserve were transferred from ComEd to
Generation, Enterprises and Exelon Business Services Company (BSC).
Approximately $37 million and $15 million of the employee severance and
relocation reserve as of June 30, 2002 relates to ComEd and Generation,
respectively, and is reflected on the Consolidated Balance Sheets of those
entities.

Approximately 3,300 Unicom and PECO positions have been identified to
be eliminated as a result of the merger. Exelon has terminated 2,255 employees
as of June 30, 2002 of which 510 were terminated in the second quarter of 2002.
The remaining positions are expected to be eliminated by the end of 2002.


10. LONG-TERM DEBT (Exelon and ComEd)
On June 13, 2002, ComEd issued $200 million of 6.15% First Mortgage
Bonds, due March 15, 2012. The $200 million bond issuance was a refinancing of
the $200 million of 8.5% First Mortgage Bonds redeemed on July 15, 2002 at a
redemption price of 103.915% of the principal amount.


37


In connection with the issuance of the $200 million of First Mortgage
Bonds, ComEd settled a forward starting interest rate swap in the notional
amount of $75 million resulting in a $1 million loss recorded in other
comprehensive income, which is being amortized over the expected remaining life
of the related debt.

On April 15, 2002, ComEd issued $100 million of Illinois Development
Finance Authority floating-rate Pollution Control Revenue Refunding Bonds,
Series 2002. The $100 million bond issuance was used to redeem $100 million of
7.25% Illinois Development Finance Authority Pollution Control Revenue Refunding
Bonds, Series 1991.

On March 13, 2002, ComEd issued $400 million of 6.15% First Mortgage
Bonds, due March 15, 2012. This $400 million bond issuance refinanced other
First Mortgage Bonds. In connection with the issuance of $400 million of First
Mortgage Bonds, ComEd settled forward starting interest rate swaps in the
aggregate notional amount of $375 million resulting in a $9 million loss
recorded in other comprehensive income, which is being amortized over the
expected remaining life of the related debt.

On March 21, 2002, ComEd redeemed $200 million of 8.625% First Mortgage
Bonds at the redemption price of 103.84% of the principal amount. These bonds
had a maturity date of February 1, 2022.

During the six months ended June 30, 2002, ComEd recorded prepayment
premiums of $9 million, partially offset by net unamortized premiums, discounts
and debt issuance expenses of $2 million, associated with the early retirement
of debt in 2002 that have been deferred by ComEd in regulatory assets and will
be amortized to interest expense over the life of the related new debt issuance
consistent with regulatory recovery.


11. SALE OF ACCOUNTS RECEIVABLE (Exelon and PECO)
PECO is party to an agreement, which expires in November 2005, with a
financial institution under which it can sell or finance with limited recourse
an undivided interest, adjusted daily, in up to $225 million of designated
accounts receivable. As of June 30, 2002, PECO had sold a $225 million interest
in accounts receivable, consisting of a $170 million interest in accounts
receivable that PECO accounted for as a sale under SFAS No. 140, "Accounting for
Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,
a Replacement of FASB Statement No. 125" and a $55 million interest in
special-agreement accounts receivable which were accounted for as a long-term
note payable. PECO retains the servicing responsibility for these receivables.
The agreement requires PECO to maintain the $225 million interest, which, if not
met, requires cash, which would otherwise be received by PECO under this
program, to be held in escrow until the requirement is met. At June 30, 2002,
PECO met this requirement.

13. NEW ACCOUNTING PRONOUNCEMENTS (Exelon, ComEd, PECO and Generation)
In June 2001, the FASB issued SFAS No. 143, "Asset Retirement
Obligations" (SFAS No. 143). In April 2002, the FASB issued SFAS No. 145, "
Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No.
13, and Technical Corrections" (SFAS No. 145). In July 2002, the FASB issued
SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities"
(SFAS No. 146).

SFAS No. 143 provides accounting requirements for retirement
obligations associated with tangible long-lived assets. Exelon expects to adopt
SFAS No. 143 on January 1, 2003. Retirement obligations associated with
long-lived assets included within the scope of SFAS No. 143 are those for which
there is a legal obligation to settle under existing or enacted law, statute,
written or oral contract or by legal construction under the doctrine of
promissory estoppel. Adoption of SFAS No. 143 will change the accounting for the
decommissioning of Exelon's nuclear generating plants as well as certain other
long-lived assets.

Currently, Generation records the obligation for decommissioning
ratably over the lives of the plants. The January 1, 2003 adoption of SFAS No.
143 will require a cumulative effect adjustment effective the date of adoption
to adjust plant assets and decommissioning liabilities to the values they would
have been had this standard been employed from the in-service dates of the
plants.

As it relates to nuclear decommissioning, the effect of this cumulative
adjustment will be to change the decommissioning liability to reflect the fair
value of the decommissioning obligation at the balance sheet date. Additionally,
the standard will require the accrual of an asset related to the decommissioning
obligation, which will be amortized over the remaining lives of the plants. The
net difference between the asset recognized and the


43


liability recorded upon adoption of SFAS No. 143 will be charged to earnings and
recognized as a cumulative effect, net of expected regulatory recovery. The
decommissioning liability to be recorded represents an obligation for the future
decommissioning of the plants, and as a result accretion expense will be accrued
on this liability until such time as the obligation is satisfied.

Exelon, ComEd, PECO and Generation are in the process of evaluating the
impact of SFAS No. 143 on their financial statements, and cannot determine the
ultimate impact of adoption at this time, however, the cumulative effect could
be material to earnings. Additionally, although over the life of the plant the
charges to earnings for the depreciation of the asset and the interest on the
liability will be equal to the amounts currently recognized as decommissioning
expense, the timing of those charges will change and in the near-term period
subsequent to adoption, the depreciation of the asset and the interest on the
liability could result in an increase in expense.

SFAS No. 145 eliminates SFAS No. 4 "Reporting Gains and Losses from
Extinguishment of Debt" (SFAS No. 4) and thus allows for only those gains or
losses on the extinguishment of debt that meet the criteria of extraordinary
items to be treated as such in the financial statements. SFAS No. 145 also
amends Statement of Financial Accounting Standards No. 13, "Accounting for
Leases" (SFAS No. 13) to require sale-leaseback accounting for certain lease
modifications that have economic effects that are similar to sale-leaseback
transactions. The provisions of this statement relating to the rescission of
SFAS No. 4 are effective for fiscal years beginning after May 15, 2002, the
provisions of this statement relating to the amendment of SFAS No. 13 are
effective for transactions occurring after May 15, 2002, and all other
provisions of this Statement are effective for financial statements issued on or
after May 15, 2002. Exelon, ComEd, PECO and Generation are in the process of
evaluating the impact of SFAS No. 145 on their financial statements, and do not
expect the impact to be material.

SFAS No. 146 requires that the liability for costs associated with exit
or disposal activities be recognized when incurred, rather than at the date of a
commitment to an exit or disposal plan. SFAS No. 146 is to be applied
prospectively to exit or disposal activities initiated after December 31, 2002.


14. CHANGE IN ACCOUNTING ESTIMATE (Exelon, ComEd and Generation)
Effective April 1, 2001, Generation changed its accounting estimates
related to the depreciation and decommissioning of certain generating stations.
The estimated service lives were extended by 20 years for three nuclear
stations, by periods of up to 20 years for certain fossil stations and by 50
years for a pumped storage station. Effective July 1, 2001, the estimated
service lives were extended by 20 years for the remainder of Exelon's operating
nuclear stations. These changes were based on engineering and economic
feasibility studies performed by Generation considering, among other things,
future capital and maintenance expenditures at these plants. As a result of the
change, net income for the three months and six months ended June 30, 2002
increased $25 million ($16 million, net of income taxes) and $60 million ($36
million, net of income taxes), respectively.



44


Effective April 1, 2002, ComEd changed its accounting estimate related
to the allowance for uncollectible accounts. This change was based on an
independently prepared evaluation of the risk profile of ComEd's customer
accounts receivable. As a result of the new evaluation, the allowance for
uncollectible accounts reserve was reduced by $11 million in the second quarter
of 2002.


15. SUBSEQUENT EVENTS
On July 1, 2002, Exelon Generation notified Midwest Generation of the
exercise of its call options under the existing Coal Generation Purchase Power
Agreement. Exelon Generation exercised options on 1,265 MWs of capacity and did
not exercise options on 2,684 MWs of capacity. In 2003, Exelon Generation will
take 1,696 MWs of non-option capacity and 1,265 MWs of option capacity under the
existing contract.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

(Dollars in millions, unless otherwise noted)

EXELON CORPORATION

GENERAL

Exelon Corporation (Exelon), through its subsidiaries, operates in
three business segments:

o Energy Delivery, consisting of the retail electricity distribution and
transmission businesses of Commonwealth Edison Company (ComEd) in
northern Illinois and PECO Energy Company (PECO) in southeastern
Pennsylvania and the natural gas distribution business of PECO in the
Pennsylvania counties surrounding the City of Philadelphia.
o Generation, consisting of Exelon Generation Company, LLC's (Generation)
electric generating facilities, energy marketing operations and equity
interests in Sithe Energies, Inc. (Sithe) and AmerGen Energy Company,
LLC (AmerGen).
o Enterprises, consisting of Exelon Enterprises Company, LLC's
(Enterprises) competitive retail energy sales, energy and
infrastructure services, communications and other investments weighted
towards the communications, energy services and retail services
industries.

See Note 6 of the Combined Notes to Consolidated Financial Statements
for further segment information.

Generation early adopted the provision of Emerging Issues Task Force
(EITF) Issue 02-3 "Accounting for Contracts Involved in Energy Trading and Risk
Management Activities" (EITF 02-3) issued by the Financial Accounting Standards
Board (FASB) EITF in June 2002 that requires revenues and energy costs related
to energy trading contracts to be presented on a net basis in the income
statement. For comparative purposes, energy costs related to energy trading have
been reclassified in prior periods to revenue to conform with the net basis of
presentation required by EITF 02-3.

RESULTS OF OPERATIONS

Three Months Ended June 30, 2002 Compared To Three Months Ended June 30, 2001

Net Income and Earnings Per Share

Net income increased $170 million, or 54%, for the three months ended
June 30, 2002. Diluted earnings per common share increased $0.53 per share, or
55%. The increase in net income reflects the gain on Enterprises' sale of its
49% interest in AT&T Wireless PCS of Philadelphia, LLC (AT&T Wireless), higher
earnings in Energy Delivery, primarily related to an increase in retail sales
due to warmer summer weather, the discontinuation of goodwill amortization at
Energy Delivery and Enterprises required by the adoption of FASB Statement of
Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible
Assets" (SFAS No. 142) and certain other factors affecting net income, which are
discussed in the remainder of the results of operations section.

Energy Delivery's gross margin (revenue net of purchased power and
fuel) increased $9 million, $25 million of which was attributable to warmer
summer weather in the second quarter



47


of 2002 as compared to the second quarter of 2001 in the ComEd service
territory, which increased retail electric volume. The retail increase was
offset by lower wholesale sales volume.

Lower operating and maintenance expense reflects a reduction in bad
debt expense due to a change in estimate and lower system repair and storm
restoration costs, partially offset by costs associated with the deployment of
automated meter reading technology and increased corporate allocations.

Energy Delivery's depreciation and amortization expense decreased by
$25 million reflecting $33 million for the discontinuation of goodwill
amortization due to the adoption of SFAS No. 142 as of January 1, 2002,
partially offset by $9 million of higher regulatory asset amortization.

As required by the Illinois Restructuring Act, ComEd made a
notification filing with the Illinois Commerce Commission (ICC) to reflect lower
depreciation rates effective July 1, 2002. No ICC approval is required for the
new rates to take effect. The anticipated annual reduction in depreciation
expense is estimated to be approximately $100 million.

Lower interest expense reflects a reduction in debt outstanding and
lower interest rates due to debt refinancing. The reduction in other, net,
primarily reflects lower intercompany interest income reflecting lower interest
rates.

Energy Delivery's effective income tax rate was 38.3% for the three
months ended June 30, 2002, compared to 42.2% for the three months ended June
30, 2001. The decrease in the effective tax rate was primarily attributable to
the discontinuation of goodwill amortization as of January 1, 2002, which was
not deductible for income tax purposes, and a reduction in state income taxes.

(1) Bundled service reflects deliveries to customers taking electric service
under tariffed rates, which include the cost of energy and the delivery
cost of the transmission and the distribution of the energy. PECO's
tariffed rates also include a CTC charge.
(2) Unbundled service reflects customers electing to receive electric
generation service from an alternative energy supplier or ComEd's PPO.
Revenue from customers choosing an alternative energy supplier includes a
distribution charge and a CTC. Revenues from customers choosing ComEd's PPO
includes an energy charge at market rates, transmission, and distribution
charges and a CTC. Transmission charges received from alternative energy
suppliers are included in wholesale and miscellaneous revenue.
(3) Wholesale and miscellaneous revenues include sales to alternative energy
suppliers, transmission revenue, sales to municipalities and other
wholesale energy sales.



The changes in electric retail revenues for the three months ended June
30, 2002, as compared to the same period in 2001 are attributable to the
following:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Rate Changes $ (14)
Customer Choice 46
Weather 41
Other Effects 32
- ---------------------------------------------------------------------------------------------------------------------
Electric Retail Revenue $ 105
- ---------------------------------------------------------------------------------------------------------------------


o Rate Changes. The decrease in revenues attributable to rate changes
reflects the 5% ComEd residential rate reduction, effective October 1,
2001, required by the Illinois restructuring legislation partially offset
by $13 million due to an increase in PECO's gross receipts tax rate. The
increase in PECO's gross receipts tax


50


rate will increase PECO's annual revenue and tax obligation by
approximately $50 million in 2002.
o Customer Choice. All ComEd and PECO customers have the choice to purchase
energy from other suppliers. This choice generally does not impact kWh
deliveries, but affects revenue collected from customers related to energy
supplied by Energy Delivery. On May 1, 2002, all ComEd residential
customers were eligible to choose their supplier of electricity, however;
as of June 30, 2002, no alternative electric supplier has sought approval
from the ICC and no electric utilities have chosen to enter the ComEd
residential market for the supply of electricity.
The favorable customer choice effect is attributable to increased
revenues of $85 million from customers in Pennsylvania selecting or
returning to PECO as their electric generation supplier, partially offset
by a decrease in revenues of $39 million from customers in Illinois
electing to purchase energy from an Alternative Retail Electric Supplier
(ARES) or the PPO, under which customers can purchase power from ComEd at a
market-based rate. ComEd and PECO continue to collect delivery charges from
these customers.
o Weather. The demand for electricity and gas services is impacted by weather
conditions. Very warm weather in summer months and very cold weather in
other months is referred to as "favorable weather conditions", because
these weather conditions result in increased sales of electricity and gas.
Conversely, mild weather reduces demand.
The weather impact was favorable compared to the prior year as a
result of warmer summer weather in the ComEd service territory during the
second quarter of 2002 as compared to the same period in 2001.
o Other Effects. Other items increasing revenues were primarily related to a
$39 million favorable volume variance other than weather, due to the impact
of a strong housing construction market in Chicago partially offset by the
impact of a slower economy on large commercial and industrial customers.

The reduction in wholesale revenue for the three months ended June 30,
2002 as compared to the three months ended June 30, 2001 reflects a $10 million
decrease due to the expiration of wholesale contracts that were offered by ComEd
from June 2000 to May 2001 to support the open access program in Illinois and a
2001 $15 million reversal of reserve for revenue refunds related to certain of
ComEd's municipal customers as a result of a favorable FERC ruling.

On July 19, 2002, ComEd filed a request with the ICC to revise the
Provider of Last Resort (POLR) obligation in Illinois. ComEd is seeking
permission from the ICC to limit the availability by June 2006 of Rate 6L for
370 of ComEd's largest energy customers with demands of at least three MWs,
totaling approximately 2,500 MWs. Rate 6L is a bundled fixed rate offered to
large customers including heavy industrial plants, large office buildings,
government facilities and a variety of other businesses. The ICC has 120 days to
act on the filing or it will be deemed approved.

- ---------------------------------------------------------------------------------------------------------------------
Gas Revenue $ (28)
- ---------------------------------------------------------------------------------------------------------------------


o Rate Changes. The unfavorable variance in rates is attributable to an
adjustment of the purchased gas cost recovery by the Pennsylvania Public
Utilities Commission (PUC) effective in December 2001. The average rate per
million cubic feet for all customers for the quarter ended June 30, 2002
was 28% lower than the same 2001 period. PECO's gas rates are subject to
periodic adjustments by the PUC designed to recover or refund the
difference between actual cost of purchased gas and the amount included in
base rates and to recover or refund increases or decreases in certain state
taxes not recovered in base rates.
o Weather. The weather impact was neutral during the quarter ended June 30,
2002 as compared to the same 2001 period. Heating degree-days were
consistent in the quarter ended June 30, 2002 compared to the same 2001
period.
o Volume. Exclusive of weather impacts, delivery volume was consistent for
the quarter ended June 30, 2002 compared to the same 2001 period.

NET INCOME $ 84 $ 71 13 18.3%
- -------------------------------------------------------------------------------------------------------


Net income for the three months ended June 30, 2002 was positively
impacted by increased revenue from retail affiliates, increased revenue from the
acquisition of two generating plants in April 2002 and reduced depreciation and
interest expense, partially offset by depressed wholesale market prices for
energy. Operating revenues, net of fuel and purchased power, decreased by $2
million. Lower wholesale market prices for energy reduced margins by $46
million, which were partially offset by increased revenue from affiliates of $43
million, revenue from the two generating plants acquired in April 2002, and
lower fuel costs. Operating and maintenance expense increased by $6 million due
to additional employee benefit costs of $9 million and operating costs for two
generating plants acquired in April 2002 of $3 million. These additional
expenses were partially offset by $7 million less in nuclear outage costs and
other operating cost reductions including savings from Exelon's Cost Management
Initiative. The decline in depreciation expense reflects extension of the
estimated service lives of certain generating stations in the third quarter of
2001, partially offset by additional depreciation expense on plant placed in
service after June 30, 2001, including the acquisition of two generating plants
in April 2002. Lower interest expense is due to capitalized interest and a lower
interest rate on the spent nuclear fuel obligation. Additionally, revenue for
the three months ended June 30, 2002 includes a net trading portfolio loss of
$16 million compared to a net $6 million loss for the three months ended June
30, 2001.

Generation's nuclear fleet, including AmerGen, performed at a capacity
factor of 92.1% for the three months ended June 30, 2002 compared to 93.6% the
same period in 2001. The lower capacity factor is primarily due to 72 planned
outage days in the three months ended June 30, 2002 versus 31 days in the same
period in 2001, including AmerGen. Generation's nuclear units' production costs
including AmerGen for the three months ended June 30, 2002 were $12.54 per MWh
compared to $13.02 per MWh for the same period in 2001. The reduced unit
production costs reflect additional generation due to power uprates, which more
than offset the lower capacity factor, and lower production costs due to
headcount reductions and Exelon's Cost Management Initiative in the three months
ended June 30, 2002 as compared to the same period in 2001. Generation's average
purchased power costs for wholesale operations were $39.96 per MWh for the three
months ended June 30, 2002, compared to $45.27 per MWh for the same



54


period in 2001. The decrease in purchased power costs was primarily due to
depressed wholesale power market prices.

Enterprises' net income increased $88 million for the three months
ended June 30, 2002 compared to the same period in 2001. The increase in net
income is primarily attributable to the sale of Enterprises' 49% interest in
AT&T Wireless PCS of Philadelphia, LLC (AT&T Wireless) to a subsidiary of AT&T
Wireless Services for $285 million in cash that resulted in an after-tax gain of
$116 million and higher equity in earnings of unconsolidated affiliates of $8
million primarily as a result of the discontinuance of losses on AT&T Wireless.
These increases were partially offset by $36 million of investment write-downs
and $4 million of net asset write-downs.

Operating revenues decreased $70 million, or 13%, for the three months
ended June 30, 2002, compared to the same period in 2001. The decrease in
operating revenues was attributable to lower gas sales of $12 million primarily
resulting from lower gas prices, reduced retail energy sales of $20 million from
Exelon Energy, Inc. (Exelon Energy) due to exiting the retail energy business in
the Pennsylvania, New Jersey and Maryland area (PJM market), lower revenues of
$43 million from Exelon Services, Inc. (Exelon Services) from reduced volume of
construction project revenues and lower revenues of $19 million from
InfraSource, Inc. (InfraSource) from the continued decline in the
telecommunications industry and reduced volume of construction services in that
industry. These decreases were partially offset by higher electric revenues of
$22 million primarily resulting from higher electric prices in Illinois for
Exelon Energy.


55


Enterprises' operating and other expenses, net decreased $222 million
for the three months ended June 30, 2002 compared to the same period in 2001.
The decrease is primarily attributable to a pre-tax gain of $198 million
recorded on the AT&T Wireless sale, lower gas costs of $18 million primarily
resulting from lower gas prices, lower power costs of $20 million resulting from
reduced operations of retail energy sales from Exelon Energy exiting the PJM
market, reduced costs relating to lower construction project volume at Exelon
Services of $33 million, reduced costs relating to lower volume of construction
services in the telecommunications industry at InfraSource of $18 million,
higher equity in earnings of unconsolidated affiliates of $8 million primarily
as a result of the discontinuance of losses on AT&T Wireless as a result of the
AT&T Wireless sale and lower interest expense of $6 million. These decreases
were partially offset by higher electric purchased power costs in Illinois of
$21 million for Exelon Energy, write-downs of communications investments of $27
million, write-downs of energy related investments of $9 million, a net
write-down of other assets of $4 million in 2002 and an $18 million gain in 2001
from the sale of a communications investment.

The effective income tax rate was 41.5% for the three months ended June
30, 2002, compared to 50.0% for the three months ended June 30, 2001. The
decrease in the effective tax rate was primarily attributable to the
discontinuation of goodwill amortization as of January 1, 2002, that was not
deductible for income tax purposes and a true-up of income taxes relating to a
merger between two Enterprises businesses in April 2001, partially offset by the
effect of the AT&T Wireless sale.


Six Months Ended June 30, 2002 Compared To Six Months Ended June 30, 2001

Net Income and Earnings Per Share
Exelon's income before the cumulative effect of changes in accounting
principles increased $20 million, or 3%, for the six months ended June 30, 2002.
Diluted earnings per common share on the same basis increased $0.06 per share,
or 3%. The increase in income before the cumulative effect of changes in
accounting principles reflects higher earnings due to the sale of AT&T Wireless,
warmer summer weather, and the discontinuation of goodwill amortization required
by the adoption of SFAS No. 142, partially offset by a decrease in retail sales
due to mild winter weather, lower wholesale energy prices, increased nuclear
refueling outage costs, employee severance costs and certain other factors
affecting net income, which are discussed in the remainder of the results of
operations section. Net income included net pretax charges of $10 million for
severance costs, primarily related to executive severance.

Net income decreased $222 million, or 31%, for the six months ended
June 30, 2002. Diluted earnings per common share decreased $0.69 per share, or
31%. Net income for the six months ended June 30, 2002 includes a $230 million
charge for the cumulative effect of changes in accounting principles, reflecting
goodwill impairment upon the adoption of SFAS No. 142. Net income for the six
months ended June 30, 2001 includes $12 million of income for the cumulative
effect of adopting SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities" (SFAS No. 133). See Note 2 of the Combined Notes to
Consolidated Financial Statements for further information regarding the adoption
of SFAS No. 133.

Energy Delivery's gross margin (revenue net of purchased power and
fuel) declined $79 million, $26 million of which was attributable primarily to
warmer winter weather, partially offset by warmer summer weather in the ComEd
service territory during the second quarter of 2002, which reduced retail
electric and gas volumes, and a reduction in wholesale sales volumes.

Flat operating and maintenance expense reflects increased pension and
postretirement benefit costs and increased corporate allocations, including a
portion of executive severance charges, and an increase in the provision for
injuries and damages offset by decreased system

repair and storm damage costs, a decrease in the provision for bad debt expense,
and a decrease in the provision for obsolete inventory.

Energy Delivery's depreciation and amortization expense decreased by
$46 million reflecting $64 million for the discontinuation of goodwill
amortization due to the adoption of SFAS No. 142 as of January 1, 2002,
partially offset by $17 million of higher regulatory asset amortization.

Lower interest expense reflects reductions in debt outstanding and
lower interest rates due to debt refinancing. The reduction in other - net,
primarily reflects lower intercompany interest income reflecting lower interest
rates.

Energy Delivery's effective income tax rate was 37.7% for the six
months ended June 30, 2002, compared to 42.0% for the six months ended June 30,
2001. The decrease in the effective tax rate was primarily attributable to the
discontinuation of goodwill amortization as of January 1, 2002, which was not
deductible for income tax purposes, and a reduction in state income taxes.

The changes in electric retail revenues for the six months ended June
30, 2002, as compared to the same period in 2001 are attributable to the
following:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Rate Changes $ (15)
Customer Choice 87
Weather (31)
Other Effects 26
- ---------------------------------------------------------------------------------------------------------------------
Electric Retail Revenue $ 67
- ---------------------------------------------------------------------------------------------------------------------

o Rate Changes. The decrease in revenues attributable to rate changes
reflects the 5% ComEd residential rate reduction, effective October 1,
2001, required by the Illinois restructuring legislation and the timing of
a $60 million PECO rate reduction effective January 1, 2001


60


offset by $26 million due to an increase in PECO's gross receipts tax rate
and the expiration of a 6% reduction in PECO's rates during the first
quarter of 2001.
o Customer Choice. The favorable customer choice effect is attributable to
increased revenues of $165 million from customers in Pennsylvania selecting
or returning to PECO as their electric generation supplier, partially
offset by a decrease in revenues of $78 million from customers in Illinois
electing to purchase energy from an ARES or the PPO, under which customers
can purchase power from ComEd at a market-based rate. ComEd and PECO
continue to collect delivery charges from these customers.
o Weather. The weather impact was unfavorable compared to the prior year as a
result of warmer winter weather in ComEd and PECO service territories
partially offset by warmer summer weather in the ComEd service territory
during the second quarter of 2002 as compared to the same period in 2001.
o Other Effects. Other items decreasing revenues were primarily related to a
net $58 million favorable volume variance other than weather, primarily due
to the impact of a strong housing construction market in Chicago, partially
offset by the payment of $14 million to Generation related to nuclear
decommissioning cost recovery under an agreement effective September 2001
which reduced PECO's revenue compared to the prior year, an $11 million
settlement of CTCs by a large PECO customer in 2001 and the impact of a
slower economy on large commercial and industrial customers.

The reduction in wholesale revenue for the six months ended June 30,
2002 as compared to the six months ended June 30, 2001 was due primarily to a
decrease in off-system sales due to the expiration of wholesale contracts that
were offered by ComEd from June 2000 to May 2001 to support the open access
program in Illinois, and a 2001 reversal of reserve for revenue refunds related
to certain of ComEd's municipal customers as a result of a favorable FERC
ruling.

o Rate Changes. The unfavorable variance in rates is attributable to an
adjustment of the purchased gas cost recovery by the PUC effective in
December 2001. The average rate per million cubic feet for all customers
for the quarter ended June 30, 2002 was 24% lower than the same 2001
period.
o Weather. The unfavorable weather impact is attributable to warmer winter
weather during the six months ended June 30, 2002 as compared to the same
2001 period. Heating degree-days decreased 15% in the six months ended June
30, 2002 compared to the same 2001 period.
o Volume. Exclusive of weather impacts, lower delivery volume affected
revenue by $22 million in the six months ended June 30, 2002 compared to
the same 2001 period. Total deliveries to retail customers decreased 5% in
the six months ended June 30, 2002 compared to the same 2001 period,
primarily as a result of slower economic conditions in 2002 offset by
increased customer growth.

Net income for the six months ended June 30, 2002 was adversely
impacted by a lower margin on wholesale energy sales due to depressed market
prices for energy, a reduced supply of low-cost nuclear generation, and
increased operating and maintenance expense partially offset by an increase in
revenue from affiliates and lower depreciation and interest expense. Operating



62


revenues, net of fuel and purchased power, decreased by $178 million. Lower
wholesale market prices for energy reduced margins by $184 million, which was
partially offset by increased revenues from affiliates of $26 million and lower
fuel costs. The amount of low-cost nuclear generation available for sale was
reduced due to an increased number of nuclear generating station refueling
outages in the six months ended June 30, 2002, as compared to the same period in
2001. Operating and maintenance expense increased by $35 million, primarily due
to $55 million of costs incurred for the additional refueling outages and the
acquisition of two generating plants in April 2002. These additional expenses
were partially offset by other operating cost reductions, including $10 million
related to headcount reductions, a $10 million reduction in Generation's
severance accrual and $4 million in savings related to Exelon's Cost Management
Initiative. The decline in depreciation expense reflects extension of the
estimated service lives of generating stations in the third quarter of 2001,
partially offset by additional depreciation expense on plant placed in service
after June 30, 2001, including the acquisition of two generating plants in April
2002. Lower interest expense is due to capitalized interest and a lower interest
rate on the spent nuclear fuel obligation. Additionally, trading activities were
initiated in April 2001. Revenue for the six months ended June 30, 2002 includes
a net trading portfolio loss of $16 million compared to a net $6 million loss in
the six months ended June 30, 2001.

Generation's nuclear fleet, including AmerGen, performed at a capacity
factor of 91.2% for the six months ended June 30, 2002 compared to 96.2% the
same period in 2001. Generation's nuclear units' production costs, including
AmerGen, for the six months ended June 30, 2002 were $13.38 per MWh compared to
$12.34 per MWh for the same period in 2001. The lower capacity factor and
increased unit production costs are primarily due to 153 days of planned outage
time in the six months ended June 30, 2002 versus 31 days in the same period in
2001. Generation's average purchased power costs for wholesale operations were
$36.76 per MWh for the six months ended June 30, 2002, compared to $41.81 per
MWh for the same period in 2001. The decrease in purchased power costs was
primarily due to depressed wholesale power market prices.

Enterprises' net income increased $85 million for the six months ended
June 30, 2002 compared to the same period in 2001, excluding the cumulative
effect of a change in accounting principle. The increase in net income is
primarily attributable to the AT&T Wireless sale that resulted in an after-tax
gain of $116 million and higher equity in earnings of unconsolidated affiliates
of $9 million primarily as a result of the discontinuation of losses on AT&T
Wireless as a result of the AT&T Wireless sale. These increases were partially
offset by $40 million of investment write-downs and $4 million of net asset
write-downs. Enterprises' net loss increased $158 million after reflecting the
cumulative effect of a change in accounting principle resulting from the
adoption of SFAS No. 142, which no longer allows amortization of goodwill but
requires testing goodwill for impairment on an annual basis. The impairment
booked during the first quarter, as a result of transitional impairment testing,
was $243 million net of income taxes and minority interest.

Operating revenues decreased $247 million for the six months ended June
30, 2002, compared to the same period in 2001. The decrease in operating
revenues is attributable to lower gas sales of $116 million primarily resulting
from lower gas prices, reduced retail energy sales of


65


$91 million from Exelon Energy exiting the PJM market, lower revenues of $56
million from Exelon Services from reduced volume of construction projects and
lower revenues of $29 million from InfraSource from the continued decline in the
telecommunications industry and reduced volume of construction services in that
industry. These decreases were partially offset by higher electric revenues of
$45 million primarily resulting from higher electric prices in Illinois for
Exelon Energy.

Enterprises' operating and other expenses, net decreased $392 million
for the six months ended June 30, 2002 compared to the same period in 2001. The
decrease is primarily attributable to a pre-tax gain of $198 million recorded on
the AT&T Wireless sale, lower gas costs of $107 million primarily resulting from
lower gas prices, lower purchased power costs of $114 million resulting from
reduced operations of retail energy sales from Exelon Energy exiting the PJM
market, reduced costs relating to lower construction project volume at Exelon
Services of $45 million, reduced costs relating to lower volume of construction
services in the telecommunications industry at InfraSource of $23 million, lower
interest expense of $14 million, and higher equity in earnings of unconsolidated
affiliates of $9 million primarily as a result of the discontinuance of losses
on AT&T Wireless as a result of the AT&T Wireless sale. These decreases were
partially offset by higher electric purchased power costs in Illinois of $42
million for Exelon Energy, write-downs of communications investments of $29
million, write-downs of energy related investments of $11 million, a net
write-down of other assets of $4 million in 2002 and a $28 million gain in 2001
from the sales of communications investments.

The effective income tax rate was 42.1% for the six months ended June
30, 2002, compared to 40.0% for the six months ended June 30, 2001. The increase
in the effective tax rate was primarily attributable to the AT&T Wireless sale
offset by the discontinuation of goodwill amortization as of January 1, 2002,
that was not deductible for income tax purposes.


LIQUIDITY AND CAPITAL RESOURCES

Exelon's businesses are capital intensive and require considerable
capital resources. Exelon's capital resources are primarily provided by
internally generated cash flows from operations and, to the extent necessary,
external financings including the issuance of commercial paper. Exelon's access
to external financing at reasonable terms is dependent on the credit ratings of
Exelon and its subsidiaries and the general business condition of Exelon and the
utility industry. Capital resources are used primarily to fund Exelon's capital
requirements, including construction, investments in new and existing ventures,
repayments of maturing debt and preferred securities of subsidiaries and payment
of common stock dividends. Any potential future acquisitions could require
external financing, including the issuance by Exelon of common stock.

Cash Flows from Operating Activities
Cash flows provided by operations for the six months ended June 30,
2002 were $1.6 billion compared to $2.0 billion in the six months ended June 30,
2001. Approximately 70% of 2002 cash flows provided by operations for the six
months ended June 30, 2002 were provided by Energy Delivery and approximately
30% was provided by Generation. Enterprises' cash


66


flows from operations were immaterial to Exelon for the six months ended June
30, 2002. Energy Delivery's cash flows from operating activities primarily
result from sales of electricity and gas to a stable and diverse base of retail
customers at fixed prices and are weighted toward the third quarter. Energy
Delivery's future cash flows will depend upon the ability to achieve cost
savings in operations, and the impact of the economy, weather and customer
choice on its revenues. Generation's cash flows from operating activities
primarily result from the sale of electric energy to wholesale customers,
including Energy Delivery and Enterprises. Generation's future cash flow from
operating activities will depend upon future demand and market prices for energy
and the ability to continue to produce and supply power at competitive costs.
Although the amounts may vary from period to period as a result of the
uncertainties inherent in business, Exelon expects that Energy Delivery and
Generation will continue to provide a reliable and steady source of internal
cash flow from operations for the foreseeable future.

Cash Flows from Investing Activities
Cash flows used in investing activities for the six months ended June
30, 2002 were $1.3 billion, compared to $998 million for the six months ended
June 30, 2001. The increase was primarily attributable to the $443 million
acquisition of two generating plants from TXU Corp. (TXU) and increased capital
expenditures partially offset by $285 million of proceeds from the AT&T Wireless
sale. Capital expenditures other than the TXU acquisition, by business segment
for the six months ended June 30, 2002 and 2001 are as follows:



Six Months Ended June 30,
--------------------------
2002 2001
- ---------------------------------------------------------------------------------------------------------------------

Energy Delivery $ 495 $ 581
Generation 475 301
Enterprises 28 37
Corporate and Other 30 18
- ---------------------------------------------------------------------------------------------------------------------
Total Capital Expenditures $ 1,028 $ 937
- ---------------------------------------------------------------------------------------------------------------------


Energy Delivery's capital expenditures for 2002 reflect the
continuation of efforts to further improve the reliability of its distribution
system in the Chicago region. Energy Delivery's investing activities were funded
primarily through operating activities.

Generation's capital expenditures for 2002 are for additions to and
upgrades of existing facilities (including nuclear refueling outages), nuclear
fuel, and increases in capacity at existing plants. Generation's investing
activities were funded from operating activities, borrowings from Exelon and the
use of available cash.

Generation closed the purchase of the two natural-gas and oil-fired
generating plants from TXU on April 25, 2002. The $443 million purchase was
funded with available cash and Exelon commercial paper. Exelon expects to repay
the commercial paper utilizing Generation's internal cash flows.

Capital expenditures have increased for the six months ended June 30,
2002 as compared to 2001 due to higher nuclear fuel expenditures, growth and an
increase in the number of planned


67


refueling outages, during which significant work is performed for additions to
or upgrades of existing facilities.

In February 2002, Generation entered into an agreement to loan AmerGen
up to $75 million at an interest rate of one-month LIBOR plus 2.25%. As of June
30, 2002, AmerGen had borrowed $75 million under this agreement. In July 2002,
the loan agreement and the loan were increased to $100 million and the maturity
date was extended to July 1, 2003.

Enterprises' capital expenditures for 2002 are primarily for additions
to or upgrades of existing facilities. On April 1, 2002, Exelon Enterprises
closed on the sale of its 49% interest in AT&T Wireless for $285 million in
cash. Proceeds from the transaction will be used for Exelon's general corporate
purposes.

Cash Flows from Financing Activities
Cash flows used in financing activities were $142 million in the second
quarter 2002, primarily attributable to debt service and payments of dividends
on common stock of $280 million. Debt financing activities during the six months
ended June 30, 2002 were as follows:

o ComEd issued $600 million in First Mortgage Bonds, issued $100 million of
Illinois Development Finance Authority floating-rate Pollution Control
Revenue Refunding Bonds, redeemed $100 million of 7.25% Illinois
Development Finance Authority Pollution Control Revenue Refunding Bonds,
redeemed $200 million in First Mortgage Bonds with available cash and
retired $170 million of transitional trust notes,
o PECO borrowed an additional $74 million of commercial paper and made
principal payments of $207 million on long-term debt with available cash.

Credit Issues
Exelon meets its short-term liquidity requirements primarily through
the issuance of commercial paper by Exelon, ComEd and PECO. Exelon, along with
ComEd, PECO and Generation, entered into a $1.5 billion unsecured revolving
credit facility with a group of banks. This credit facility is used principally
to support the commercial paper programs of Exelon, ComEd and PECO.

At June 30, 2002, Exelon's capital structure consisted of 60% of
long-term debt, 35% common stock, 2% notes payable and 3% preferred securities
of subsidiaries. Total debt included $6.6 billion of securitization debt
constituting obligations of certain consolidated special purpose entities,
representing 28% of capitalization.

At June 30, 2002, Exelon had outstanding $470 million of notes payable
consisting principally of commercial paper. For the six months ended June 30,
2002, the average interest rate on notes payable was approximately 1.96%.
Certain of the credit agreements to which Exelon, ComEd, PECO and Generation are
a party require each of them to maintain a debt to total capitalization ratio of
65% or less (excluding securitization debt and for PECO, excluding the
receivable from parent recorded in PECO's shareholders' equity). At June 30,
2002, the debt to total capitalization ratios on that basis for Exelon, ComEd,
PECO and Generation were 48%, 46%, 38% and 32%, respectively.


68


Exelon and its subsidiaries' access to the capital markets, including
the commercial paper market, and their financing costs in those markets are
dependent on their respective securities ratings. None of Exelon's or its
subsidiaries' borrowings is subject to default or prepayment as a result of a
downgrading of securities ratings although such a downgrading could increase
interest charges under Exelon's bank credit facility. Exelon and its
subsidiaries from time to time enter into interest rate swap and other
derivatives that require the maintenance of investment grade ratings. Failure to
maintain investment grade ratings would allow the counterparty to terminate the
derivative and settle the transaction on a net present value basis.

Under the Public Utility Holding Company Act of 1935 (PUHCA) and the
Federal Power Act, Exelon, ComEd, PECO and Generation can pay dividends only
from retained, undistributed or current earnings. However, an SEC order granted
permission to Exelon and ComEd to pay up to $500 million in dividends out of
additional paid-in capital, provided that Exelon agreed not to pay dividends out
of paid-in capital after December 31, 2002 if its common equity is less than 30%
of its total capitalization. At June 30, 2002, Exelon had retained earnings of
$1.4 billion, which includes ComEd retained earnings of $382 million, PECO
retained earnings of $277 million and Generation retained earnings of $686
million.

Contractual Obligations and Commercial Commitments
Contractual obligations represent cash obligations that are considered
to be firm commitments and commercial commitments represent commitments
triggered by future events. Exelon's contractual obligations and commercial
commitments as of June 30, 2002 were materially unchanged, other than in the
normal course of business, from the amounts set forth in the December 31, 2001
Form 10-K except for the following:
o ComEd issued $600 million of First Mortgage Bonds due March 15, 2012,
issued $100 million of Illinois Development Finance Authority floating-rate
Pollution Control Revenue Refunding Bonds, series 2002, redeemed $100
million of 7.25% Illinois Development Finance Authority Pollution Control
Revenue Refunding Bonds, series 1991, redeemed $200 million of First
Mortgage Bonds due February 1, 2022, and retired $170 million of
transitional trust notes.
o Guarantees increased $300 million primarily related to an increase in the
amount of surety bonds required by Enterprises' insurance policies.
o Insured long-term debt increased $100 million related to ComEd's issuance
of $100 million in variable rate debt that has been credit enhanced through
the purchase of insurance coverage.
o On April 25, 2002 Generation closed the purchase of two generating plants
from TXU. The $443 million purchase was funded primarily with commercial
paper issued by Exelon.
o On June 26, 2002 Generation agreed to purchase Sithe New England Holdings,
LLC (Sithe New England) for $543 million, plus the assumption of
non-recourse debt estimated to be approximately $1.2 billion at the date of
purchase. The purchase is estimated to close in November 2002, subject to
regulatory approval. See Note 3 of the Combined Notes to the Consolidated
Financial Statements for additional information about the Sithe New England
acquisition.
o Purchase obligations increased by $1.2 billion, primarily due to an
increase of $2.0 billion in power only purchases partially offset by a $0.8
billion decrease in net capacity purchase commitments. The increase in
power only purchases is primarily due to Generation's


69


agreement to purchase all the energy from Unit No. 1 at Three Mile Island
after December 31, 2001 through December 31, 2014. This decrease in net
capacity purchase commitments is due primarily to the decision not to
exercise the option to purchase 2,684 MWs of capacity from Midwest
Generation in 2002 and 2003 as well as the increase in capacity sales under
the TXU tolling agreement.

Off Balance Sheet Obligations
Generation owns 49.9% of the outstanding common stock of Sithe and has
an option, beginning on December 18, 2002, to purchase the remaining common
stock outstanding (Remaining Interest) in Sithe. The purchase option expires on
December 18, 2005. In addition, the Sithe stockholders who own in the aggregate
the Remaining Interest have the right to require Generation to purchase the
Remaining Interest (Put Rights) during the same period in which Generation can
exercise its purchase option. At the end of this exercise period, if Generation
has not exercised its purchase option and the other Sithe stockholders have not
exercised their Put Rights, Generation will have an additional one-time option
to purchase shares from the other stockholders in Sithe to bring Generation's
ownership in Sithe from the current 49.9% to 50.1% of Sithe's total outstanding
common stock.

If Generation exercises its option to acquire the Remaining Interest,
or if all the other Sithe stockholders exercise their Put Rights, the purchase
price for 70% of the Remaining Interest will be set at fair market value subject
to a floor of $430 million and a ceiling of $650 million. The balance of the
Remaining Interest will be valued at fair market value subject to a floor of
$141 million and a ceiling of $330 million. In either instance, the floor and
ceiling will accrue interest from the beginning of the exercise period.

If Generation increases its ownership in Sithe to 50.1% or more, Sithe
will become a consolidated subsidiary and Exelon's financial results will
include Sithe's financial results from the date of purchase. At June 30, 2002,
Sithe had total assets of $4.1 billion and total debt of $2.1 billion, including
$1.6 billion of non-recourse project debt of which $1.0 billion is associated
with Sithe New England, $0.4 billion of subordinated debt, $49 million of
short-term debt, $33 million of capital leases, and excluding $411 million of
non-recourse project debt associated with Sithe's equity investments. For the
six months ended June 30, 2002, Sithe had revenues of $0.6 billion. As of June
30, 2002, Generation had a $725 million equity investment in Sithe. On June 26,
2002, Generation agreed to purchase Sithe New England for $543 million plus the
assumption of approximately $1.2 billion of non-recourse project debt, which is
expected to be outstanding at the time of the closing of the purchase.
Generation expects to close the purchase of Sithe New England in November 2002,
subject to regulatory approval.

Additionally, the debt on the books of Exelon's unconsolidated equity
investments and joint ventures is not reflected on Exelon's Consolidated Balance
Sheets. Total investee debt, at June 30, 2002, including the debt of Sithe
described in the preceding paragraph, is currently estimated to be $2.3 billion
($1.2 billion based on Exelon's ownership interest of the investments).


70


Generation and British Energy plc (British Energy), Generation's joint
venture partner in AmerGen, have each agreed to provide up to $100 million to
AmerGen at any time for operating expenses.

Other Factors
Exelon's costs of providing pension and postretirement benefit plans
are dependent upon a number of factors, such as the rates of return on plan
assets, discount rate, and the rate of increase in health care costs. The market
value of plan assets has been affected by sharp declines in the equity market
since the third quarter of 2000. As a result, at December 31, 2002, Exelon could
be required to recognize an additional minimum liability as prescribed by FASB
SFAS No. 87 "Employers' Accounting for Pensions" and FASB SFAS No. 132
"Employers' Disclosures about Pensions and Postretirement Benefits." The
liability would be recorded as a reduction to common equity, and the equity
would be restored to the balance sheet in future periods when the fair value of
plan assets exceeds the accumulated benefit obligations. The amount of reduction
to common equity recorded, if any, will depend upon the asset returns
experienced in 2002, but could be material. The recording of this reduction
would not affect net income or cash flow in 2002; however, pension cost and cash
funding requirements could increase in future years without a substantial
recovery in the equity markets.

Generation is a counterparty to Dynegy Inc. (Dynegy) in various energy
transactions. In early July 2002, the credit ratings of Dynegy were downgraded
by two credit rating agencies to below investment grade. As of July 29, 2002,
Generation had a net receivable from Dynegy of less than $5 million, and
consistent with the terms of the existing credit arrangement, has requested
collateral in support of this receivable. Generation also has credit risk
associated with Dynegy through Generation's equity investment in Sithe. Sithe is
a 60% owner of the Independence generating station, a 1,040 MW gas-fired
qualified facility that has an energy only long-term tolling arrangement with
Dynegy, with a related financial swap arrangement. As of June 30, 2002, Sithe
had recognized an asset on its balance sheet related to the fair value of the
financial swap agreement with Dynegy that is marked-to-market under the terms of
SFAS No. 133. If Dynegy is unable to fulfill the terms of this agreement, Sithe
would be required to write-off the fair value asset, which Generation estimates
would result in an approximate $15 million reduction in its equity earnings from
Sithe, based on Generation's current 49.9% investment ownership in Sithe.
Additionally, the future economic value of Sithe's investment in the
Independence Station and AmerGen's purchased power arrangement with Illinois
Power, a subsidiary of Dynegy, could be impacted by events related to Dynergy's
financial condition.

The changes in electric retail revenues for the three months ended June
30, 2002, as compared to the three months ended June 30, 2001, are attributable
to the following:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Weather $ 40
Rate Changes (27)
Customer Choice (39)
Other Effects 12
- ---------------------------------------------------------------------------------------------------------------------
Electric Retail Revenue $ (14)
- ---------------------------------------------------------------------------------------------------------------------


o Weather. The demand for electricity is impacted by weather conditions. Very
warm weather in summer months and very cold weather in other months is
referred to as "favorable weather conditions", because these weather
conditions result in increased sales of electricity. Conversely, mild
weather reduces demand.
The weather impact for the three months ended June 30, 2002 was
favorable compared to the three months ended June 30, 2001 as a result of
warmer summer weather in


74


the second quarter of 2002 as compared to the second quarter of 2001.
Cooling degree-days increased 29% in the three months ended June 30, 2002
compared to the three months ended June 30, 2001.
o Rate Changes. The decrease attributable to rate changes reflects a 5%
residential rate reduction, effective October 1, 2001, required by the
Illinois restructuring legislation.
o Customer Choice. All ComEd customers have the choice to purchase energy
from other suppliers. This choice generally does not impact the volume of
deliveries, but affects revenue collected from customers related to energy
supplied by ComEd. On May 1, 2002, all ComEd residential customers were
eligible to choose their supplier of electricity, however, as of June 30,
2002, no alternative electric supplier has sought approval from the ICC and
no electric utilities have chosen to enter the ComEd residential market for
the supply of electricity.
The decrease in revenues reflects customers in Illinois electing
to purchase energy from an ARES or the PPO. As of June 30, 2002,
approximately 22,600 retail customers had elected to purchase energy from
an ARES or the ComEd PPO, an increase from 14,000 customers at June 30,
2001. The MWhs delivered to such customers increased from approximately 4.6
million for the three months ended June 30, 2001 to 5.5 million for the
three months ended June 30, 2002, or approximately a 20% increase from the
previous year.
o Other Effects. A strong housing construction market in Chicago contributed
to residential and small commercial and industrial customer volume growth,
partially offset by the unfavorable impact of a slower economy on large
commercial and industrial customers.

On July 19, 2002, ComEd filed a request with the ICC to revise the
Provider of Last Resort (POLR) obligation in Illinois. ComEd is seeking
permission from the ICC to limit the availability by June 2006 of Rate 6L for
370 of ComEd's largest energy customers with demands of at least three MWs,
totaling approximately 2,500 MWs. Rate 6L is a bundled fixed rate offered to
large customers including heavy industrial plants, large office buildings,
government facilities and a variety of other businesses. The ICC has 120 days to
act on the filing or it will be deemed approved.

The reduction in wholesale revenue for the three months ended June 30,
2002 as compared to the three months ended June 30, 2001 was due primarily to a
$10 million decrease in off-system sales due to the expiration of wholesale
contracts that were offered by ComEd from June 2000 to May 2001 to support the
open access program in Illinois and a $15 million reversal of reserve in 2001
for revenue refunds related to certain of ComEd's municipal customers as a
result of a favorable FERC ruling.

Purchased Power Expense
Purchased power expense decreased $33 million, or 6% for the three
months ended June 30, 2002. The decrease in purchased power expense was
primarily attributable to a $29 million decrease as a result of customers
choosing to purchase energy from an ARES, an $8 million decrease due to the
expiration of the wholesale contracts offered by ComEd to support the open
access program in Illinois, a $5 million decrease related to a reduction in the
average purchase price of energy and a $5 million decrease due to the effects of
the slower economy on the large commercial and industrial customers partially
offset by a $15 million increase due to favorable weather conditions.





75


Operating and Maintenance Expense
Operating and maintenance (O&M) expense decreased $28 million, or 11%,
for the three months ended June 30, 2002. The decrease in O&M expense was
primarily attributable to an $11 million decrease in bad debt expense due to a
revised estimate of the reserve for uncollectible accounts, a $4 million
decrease in corporate allocations, and a $9 million decrease in repairs of
distribution systems damaged by others and storm restoration.

Depreciation and Amortization Expense
Depreciation and amortization expense decreased $35 million, or 21%,
for the three months ended June 30, 2002. This decrease is primarily due to the
discontinuation of goodwill amortization effective January 1, 2002 upon the
adoption of SFAS No. 142 partially offset by increased depreciation based on
higher property, plant and equipment balances.

As required by the Illinois Restructuring Act, a notification filing
was made with the ICC to reflect lower depreciation rates effective July 1,
2002. No ICC approval is required for the new rates to take effect. The
anticipated annual reduction in depreciation expense is estimated to be
approximately $100 million.

Taxes Other Than Income
Taxes other than income remained consistent from period to period.

Interest Charges
Interest charges consist of interest expense and distributions on
Company-Obligated Mandatorily Redeemable Preferred Securities of Subsidiary
Trusts. Interest charges decreased $16 million, or 11%, for the three months
ended June 30, 2002. The decrease in interest charges was primarily attributable
to the impact of lower interest rates for the three months ended June 30, 2002
as compared to the three months ended June 30, 2001, the early retirement of the
$196 million of First Mortgage Bonds in November of 2001 and the retirement of
$340 million in transitional trust notes since June 2001.

Other Income and Deductions
Other income and deductions, excluding interest charges, decreased $8
million or 36%, for the three months ended June 30, 2002. The decrease was
primarily attributable to $2 million in intercompany interest income relating to
the $400 million receivable from PECO which was repaid during second quarter
2001 and a $7 million reduction in intercompany interest income from Unicom
Investment Inc., reflecting lower interest rates.

Income Taxes
The effective income tax rate was 39.5% for the three months ended June 30,
2002, compared to 45.0% for the three months ended June 30, 2001. The decrease
in the effective tax rate was primarily attributable to the discontinuation of
goodwill amortization as of January 1, 2002, which was not deductible for income
tax purposes.

(1) Bundled service reflects deliveries to customers taking electric service
under tariffed rates, which include the cost of energy and the delivery
cost of the transmission and the distribution of the energy.
(2) Revenue from customers choosing an ARES includes a distribution charge and
a CTC charge. Transmission charges received from ARES are included in
wholesale and miscellaneous revenue. Revenues from customers choosing the
PPO includes an energy charge at market rates, transmission, and
distribution charges and a CTC charge.
(3) Wholesale and miscellaneous revenues include sales to ARES, transmission
revenue, sales to municipalities and other wholesale energy sales.



The changes in electric retail revenues for the six months ended June
30, 2002, as compared to the six months ended June 30, 2001, are attributable to
the following:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Weather $ (13)
Rate Changes (54)
Customer Choice (78)
Other Effects 38
- ---------------------------------------------------------------------------------------------------------------------
Retail Revenue $ (107)
- ---------------------------------------------------------------------------------------------------------------------


o Weather. The weather impact for the six months ended June 30, 2002 was
unfavorable compared to the six months ended June 30, 2001 as a result of
warmer winter weather partially offset by warmer summer weather in 2002
compared to 2001. Heating degree-days decreased 6% and were partially
offset by a 29% increase in cooling degree-days in the six months ended
June 30, 2002 compared to the six months ended June 30, 2001
o Rate Changes. The decrease attributable to rate changes reflects a 5%
residential rate reduction, effective October 1, 2001, required by the
Illinois restructuring legislation.




79


o Customer Choice. The decrease in revenues reflects customers in Illinois
electing to purchase energy from an ARES or the PPO. As of June 30, 2002,
approximately 22,600 retail customers had elected to purchase energy from
an ARES or the ComEd PPO, an increase from 14,000 customers at June 30,
2001. The MWhs delivered to such customers increased from approximately 8.7
million for the six months ended June 30, 2001 to 10.3 million for the six
months ended June 30, 2002, approximately a 20% increase from the previous
year.
o Other Effects. A strong housing construction market in Chicago contributed
to residential and small commercial and industrial customer volume growth,
partially offset by the unfavorable impact of a slower economy on large
commercial and industrial customers.

The reduction in wholesale revenue for the six months ended June 30,
2002 as compared to the six months ended June 30, 2001 was due primarily to a
$38 million decrease in off-system sales due to the expiration of wholesale
contracts that were offered by ComEd from June 2000 to May 2001 to support the
open access program in Illinois, a $15 million reversal of reserve for revenue
refunds in 2001 related to certain of ComEd's municipal customers as a result of
a favorable FERC ruling, and $20 million of other miscellaneous revenue.

Purchased Power Expense
Purchased power expense decreased $104 million, or 9% for the six
months ended June 30, 2002. The decrease in purchased power expense was
primarily attributable to a $5 million decrease due to unfavorable weather
conditions, a $62 million decrease as a result of customers choosing to purchase
energy from an ARES, and a $34 million decrease due to the expiration of the
wholesale contracts offered by ComEd to support the open access program in
Illinois.

Operating and Maintenance Expense
O&M expense remained relatively consistent from period to period.

Depreciation and Amortization Expense
Depreciation and amortization expense decreased $66 million, or 20%,
for the six months ended June 30, 2002. This decrease is primarily due to the
discontinuation of goodwill amortization effective January 1, 2002 upon the
adoption of SFAS No. 142 partially offset by increased depreciation based on
higher property plant and equipment balances.

Taxes Other Than Income
Taxes other than income remained consistent from period to period.

Interest Charges
Interest charges decreased $32 million, or 11%, for the six months
ended June 30, 2002. The decrease in interest charges was primarily attributable
to the impact of lower interest rates for the six months ended June 30, 2002 as
compared to the six months ended June 30, 2001, the early retirement of the $196
million of First Mortgage Bonds in November of 2001 and the retirement of $340
million in transitional trust notes since June 2001.




80


Other Income and Deductions
Other income and deductions, excluding interest charges, decreased $30
million, or 51%, for the six months ended June 30, 2002. The decrease was
primarily attributable to $8 million in intercompany interest income relating to
the $400 million receivable from PECO which was repaid during the second quarter
of 2001, and a $22 million reduction in intercompany interest income from Unicom
Investment Inc., reflecting lower interest rates.

Income Taxes
The effective income tax rate was 39.6% for the six months ended June
30, 2002, compared to 45.2% for the six months ended June 30, 2001. The decrease
in the effective tax rate was primarily attributable to the discontinuation of
goodwill amortization as of January 1, 2002, which was not deductible for income
tax purposes.

LIQUIDITY AND CAPITAL RESOURCES

ComEd's business is capital intensive and requires considerable capital
resources. ComEd's capital resources are primarily provided by internally
generated cash flows from operations and, to the extent necessary, external
financing including the issuance of commercial paper. ComEd's access to external
financing at reasonable terms is dependent on its credit ratings and the general
business condition of ComEd and the utility industry. Capital resources are used
primarily to fund ComEd's capital requirements, including construction,
repayments of maturing debt, and the payment of common stock dividends.

Cash Flows from Operating Activities
Cash flows provided by operations were $740 million for the six months
ended June 30, 2002 compared to $705 million for the six months ended June 30,
2001. The increase in cash flows in 2002 was primarily attributable to a $107
million increase in other operating activities partially offset by a $67 million
decrease in working capital. ComEd's future cash flows will depend upon the
ability to achieve cost savings in operations, the impact of the economy,
weather, and customer choice on its revenues. Although the amounts may vary from
period to period as a result of uncertainties inherent in the business, ComEd
expects to continue to provide a reliable and steady source of internal cash
flow from operations for the foreseeable future.

Cash Flows from Investing Activities
Cash flows used in investing activities were $352 million for the six
months ended June 30, 2002 compared to $58 million for the six months ended June
30, 2001. The increase in cash flows used in investing activities in 2002 was
primarily attributable to the paydown of the $400 million outstanding receivable
with PECO in the second quarter of 2001 partially offset by an $87 million
decrease in capital expenditures. ComEd's investing activities for the six
months ended June 30, 2002 were funded primarily through operating activities.

ComEd estimated that it will spend approximately $781 million in total
capital expenditures for 2002. Approximately two thirds of the budgeted 2002
expenditures are for continuing efforts to further improve the reliability of
its transmission and distribution systems. The remaining one third is for
capital additions to support new business and customer growth. ComEd anticipates
that it will obtain financing, when necessary, through borrowings, the



81


issuance of preferred securities, or capital contributions from Exelon. ComEd's
proposed capital expenditures and other investments are subject to periodic
review and revision to reflect changes in economic conditions and other factors.

Cash Flows from Financing Activities
Cash flows used in financing activities were $57 million for the six
months ended June 30, 2002 as compared to $322 million for the six months ended
June 30, 2001. Cash flows used in financing activities were primarily
attributable to debt service and payments of dividends to Exelon. ComEd's debt
financing activities for the six months ended June 30, 2002 reflected the
issuance of $600 million in First Mortgage Bonds, the issuance of $100 million
of 7.25% Illinois Development Finance Authority floating-rate Pollution Control
Revenue Refunding Bonds, the retirement of $170 million of transitional trust
notes, the early retirement of $200 million in First Mortgage Bonds with
available cash, and the redemption of $100 million of Illinois Development
Finance Authority Pollution Control Revenue Refunding Bonds. For the six months
ended June 30, 2001, ComEd's debt financing activities reflected the retirement
of $170 million of transitional trust notes. ComEd paid a $235 million dividend
to Exelon during the six months ended June 30, 2002 compared to a $148 million
dividend for the six months ended June 30, 2001.

Credit Issues
ComEd meets its short-term liquidity requirements primarily through the
issuance of commercial paper, borrowings under bank credit facilities and
borrowings from the Exelon intercompany money pool. ComEd, along with Exelon,
PECO and Generation entered into a $1.5 billion unsecured 364-day revolving
credit facility on December 12, 2001 with a group of banks. ComEd has a $300
million sublimit under the credit facility and expects to use the credit
facility principally to support its $300 million commercial paper program. This
credit facility requires ComEd to maintain a debt to total capitalization ratio
of 65% or less (excluding transitional trust notes). At June 30, 2002, ComEd's
debt to total capitalization ratio on that basis was 46%. At June 30, 2002,
ComEd had no short-term borrowings.

ComEd's access to the capital markets, including the commercial paper
market, and its financing costs in those markets are dependent on its securities
ratings. None of ComEd's borrowings are subject to default or prepayment as a
result of a downgrading of securities ratings although such a downgrading could
increase interest charges under certain bank credit facilities. ComEd from time
to time enters into interest rate swaps and other derivatives that require the
maintenance of investment grade ratings. Failure to maintain investment grade
ratings would allow the counterparty to terminate the derivative and settle the
transaction on a net present value basis.

At June 30, 2002, ComEd's capital structure, excluding the deduction
from shareholders' equity of the $875 million receivable from Exelon, consisted
of 52% long-term debt, 46% of common stock, and 2% of preferred securities of
subsidiaries. Long-term debt included $2.1 billion of transitional trust notes
constituting obligations of certain consolidated special purpose entities
representing 16% of capitalization.



82


Under PUHCA and the Federal Power Act, ComEd can only pay dividends
from retained or current earnings. However, the SEC has authorized ComEd to pay
up to $500 million in dividends out of additional paid-in capital, provided
ComEd may not pay dividends out of paid-in capital after December 31, 2002 if
its common equity is less than 30% of its total capitalization (including
transitional trust notes). At June 30, 2002, ComEd had retained earnings of $382
million.

Contractual Obligations and Commercial Commitments
Contractual obligations represent cash obligations that are considered
to be firm commitments and commercial commitments represent commitments
triggered by future events. ComEd's contractual obligations and commercial
commitments as of June 30, 2002 were materially unchanged, other than in the
normal course of business, from the amounts as set forth in the December 31,
2001 Form 10-K except for the issuance of $600 million of First Mortgage Bonds
due March 15, 2012, the issuance of $100 million of Illinois Development Finance
Authority floating-rate Pollution Control Revenue Refunding Bonds, Series 2002,
the redemption of $100 million of 7.25% Illinois Development Finance Authority
Pollution Control Revenue Refunding Bonds, Series 1991, the redemption of $200
million of First Mortgage Bonds due February 1, 2022, and the retirement of $170
million in transitional trust notes.

The changes in electric retail revenues for the quarter ended June 30,
2002, as compared to the same 2001 period, are as follows:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Customer Choice $ 85
Rate Changes 13
Weather 1
Other Effects 19
- ---------------------------------------------------------------------------------------------------------------------
Electric Retail Revenue $ 118
- ---------------------------------------------------------------------------------------------------------------------


o Customer Choice. All PECO customers have choice to purchase energy from
other suppliers. This choice generally does not impact kWh deliveries, but
reduces revenue collected from customers because they are not obtaining
generation supply from PECO.
As of June 30, 2002, the customer load served by alternate
suppliers was 991 MW or 12.8% as compared to 1,102 MW or 14.5% as of June
30, 2001. For the quarter ended June 30, 2002, the percent of PECO's total
retail deliveries for which PECO was the electric supplier was 93.4% in
2002, an 18.3% increase as compared to 75.1% in 2001. As of June 30, 2002,
the number of customers served by alternate suppliers was 308,866 or 20.2%
as compared to June 30, 2001 of 400,972 or 26.4%. The increases in the
customer load and the percentage of MWh served by PECO, and the decrease in
the number of customers served by alternative suppliers primarily resulted
from customers selecting or returning to PECO as their electric generation
supplier.
In February 2002, New Power Company (New Power) notified PECO of
its intent to withdraw from providing Competitive Default Service (CDS) to
approximately 180,000 residential customers. As a result of that
withdrawal, those CDS customers were returned to PECO in the second quarter
of 2002. Pursuant to a tariff filing approved by the Pennsylvania Public
Utility Commission (PUC), PECO will serve those returned customers at the
discount energy rates on generation provided for under the original New
Power CDS Agreement for the remaining term of that contract. Subsequently,
in the second quarter of 2002, New Power also advised PECO it planned to
withdraw from serving all of its customers in Pennsylvania, including
approximately 15,000 non-CDS PECO customers, and to return those customers
to PECO in September.
o Rate Changes. The increase in revenues attributable to rate changes
primarily reflects a $13 million increase due to an increase in the gross
receipts tax rate effective January 1, 2002.
As permitted by the Pennsylvania Electric Competition Act, the
Pennsylvania Department of Revenue has calculated a 2002 Revenue Neutral
Reconciliation (RNR) adjustment to the gross receipts tax rate in order to
neutralize the impact of electric restructuring on its tax revenues. The
RNR adjustment increases the gross receipts tax rate, which will increase
PECO's annual revenues and tax obligations by approximately $50 million in
2002. In January 2002, the PUC approved the adjustment to the gross
receipts tax rate, which was implemented effective January 1, 2002. The RNR
adjustment is under appeal.
o Weather. The demand for electricity and gas services is impacted by weather
conditions. Very warm weather in summer months and very cold weather in
other months is referred to as "favorable weather conditions", because
these weather conditions result in increased sales of electricity and gas.
Conversely, mild weather reduces demand.



86


The weather impact was favorable compared to the prior year as a result
of warmer summer weather.
o Other Effects. Other items affecting revenue during the quarter ended June
30, 2002 include:
o Volume. Exclusive of weather impacts, higher delivery volume affected
PECO's revenue by $24 million compared to the same 2001 period.
o Other. The payment of $7 million to Generation related to nuclear
decommissioning cost recovery under an agreement effective September
2001, which reduced PECO's revenue compared to the prior year.

PECO's gas sales statistics for the quarter ended June 30, 2002 as
compared to the same 2001 period are as follows:



For the three months ended June 30,

Weather --
Volume (1)
Other 1
- ---------------------------------------------------------------------------------------------------------------------
Gas Revenue $ (28)
- ---------------------------------------------------------------------------------------------------------------------


o Rate Changes. The unfavorable variance in rates is attributable to an
adjustment of the purchased gas cost recovery by the PUC effective in
December 2001. The average rate per million cubic feet for all customers
for the quarter ended June 30, 2002 was 28% lower than the same 2001
period. PECO's gas rates are subject to periodic adjustments by the PUC
designed to recover or refund the difference between actual cost of
purchased gas and the amount included in base rates and to recover or
refund increases or decreases in certain state taxes not recovered in base
rates.
o Weather. The weather impact was neutral during the quarter ended June 30,
2002 compared to the same 2001 period.
o Volume. Exclusive of weather impact, delivery volume was consistent for the
quarter ended June 30, 2002 compared to the same 2001 period.





87


Purchased Power and Fuel Expense
Purchased power and fuel expense for the quarter ended June 30, 2002
increased $64 million as compared to the same 2001 period. The increase in fuel
and purchased power expense was primarily attributable to $73 million from
customers in Pennsylvania selecting or returning to PECO as their electric
generation supplier, $9 million primarily attributable to higher delivery volume
and higher PJM ancillary charges of $8 million. These increases were partially
offset by $28 million from lower gas prices.

Operating and Maintenance Expense
O&M expense for the quarter ended June 30, 2002 increased $5 million,
or 4%, as compared to the same 2001 period. The increase in O&M expense was
primarily attributable to $5 million related to the deployment of automated
meter reading technology and $3 million related to an increased allocation of
corporate expense.

Depreciation and Amortization Expense
Depreciation and amortization expense for the quarter ended June 30,
2002 increased $10 million, or 10%, as compared to the same 2001 period. The
increase was primarily attributable to $9 million of additional amortization of
PECO's CTC and an increase of $1 million related to depreciation expense
associated with additional plant in service. The additional amortization of the
CTC is in accordance with PECO's original settlement under the Pennsylvania
Competition Act.

Taxes Other Than Income
Taxes other than income for the quarter ended June 30, 2002 increased
$22 million, or 54%, as compared to the same 2001 period. The increase was
primarily attributable to additional gross receipts tax related to additional
revenues and an increase in the gross receipts tax rate on electric revenue
effective January 1, 2002.

Interest Charges
Interest charges consist of interest expense and distributions on
Company-Obligated Mandatorily Redeemable Preferred Securities of a Partnership
(COMRPS). Interest charges decreased $27 million, or 21% in the quarter ended
June 30, 2002 as compared to the same 2001 period. The decrease was primarily
attributable to lower interest expense on long-term debt of $22 million as a
result of principal payments and lower interest rates and interest expense
related to a loan from an affiliate in 2001 of $2 million.

Other Income and Deductions
Other income and deductions excluding interest charges remained
consistent in the quarter ended June 30, 2002 as compared to the same 2001
period.

Income Taxes
The effective tax rate was substantially unchanged at 34.5% for the
quarter ended June 30, 2002 as compared to 34.1% for the same 2001 period.



88


Preferred Stock Dividends
Preferred stock dividends for the quarter ended June 30, 2002 were
consistent as compared to the same 2001 period.

Net income on common stock decreased $25 million, or 12% for the six
months ended June 30, 2002 as compared to the same 2001 period. The decrease was
a result of lower margins due to the unplanned return of certain residential,
commercial and industrial customers, milder weather, increased depreciation and
amortization expense, partially offset by favorable rate adjustments.

The changes in electric retail revenues for the six months ended June
30, 2002, as compared to the same 2001 period, are as follows:



Variance
- ---------------------------------------------------------------------------------------------------------------------

Customer Choice $ 165
Rate Changes 39
Weather (18)
Other Effects (12)
- ---------------------------------------------------------------------------------------------------------------------
Electric Retail Revenue $ 174
- ---------------------------------------------------------------------------------------------------------------------



o Customer Choice. As of June 30, 2002, the customer load served by alternate
suppliers was 991 MW or 12.8% as compared to 1,102 MW or 14.5% as of June
30, 2001. For the six months ended June 30, 2002, the percent of PECO's
total retail deliveries for which PECO was the electric supplier was 90.9%
in 2002, an 18.2% increase as compared to 72.7% in 2001. As of June 30,
2002, the number of customers served by alternate suppliers was 308,866 or
26.4% as compared to June 30, 2001 of 400,972 or 26.4%. This increase in
the customer load and the percentage of MWh served by PECO, and the
decrease in the number of customers served by alternative suppliers
primarily resulted from customers selecting or returning to PECO as their
electric generation supplier.
o Rate Changes. The increase in revenues attributable to rate changes
primarily reflects the expiration of a 6% reduction in PECO's electric
rates during the first quarter of 2001 and a $26 million increase as a
result of the increase in the gross receipts tax rate effective January 1,
2002. These increases are partially offset by the timing of a $60 million
rate reduction in effect for 2001 and 2002.
o Weather. The weather impact was unfavorable compared to the prior year
primarily as a result of warmer winter weather. Heating degree-days
decreased 15% for the six months ended June 30, 2002 compared to the same
2001 period.
o Other Effects. Other items affecting revenue during the six months ended
June 30, 2002 include:
o Volume. Exclusive of weather impacts, higher delivery volume increased
PECO's revenue by $7 million compared to the same 2001 period.
o Other. The payment of $14 million to Generation related to nuclear
decommissioning cost recovery under an agreement effective September
2001 which reduced PECO's revenue compared to the prior year and an
$11 million settlement of CTCs by a large customer in the first
quarter of 2001.

PECO's gas sales statistics for the six months ended June 30, 2002 as
compared to the same 2001 period are as follows:



2002 2001 Variance

The changes in gas revenue for the six months ended June 30, 2002, as
compared to the same 2001 period, are as follows:

Rate Changes $ (63)
Weather (30)
Volume (22)
Other 1
- ---------------------------------------------------------------------------------------------------------------------
Gas Revenue $ (114)
- ---------------------------------------------------------------------------------------------------------------------


o Rate Changes. The unfavorable variance in rates is attributable to an
adjustment of the purchased gas cost recovery by the PUC effective in
December 2001. The average rate per million cubic feet for all customers
for the six months ended June 30, 2002 was 24% lower than the same 2001
period.
o Weather. The unfavorable weather impact is attributable to warmer winter
weather during the six months ended June 30, 2002 as compared to the same
2001 period. Heating degree-days decreased 15% in the six months ended June
30, 2002 compared to the same 2001 period.
o Volume. Exclusive of weather impacts, lower delivery volume affected
revenue by $22 million in the six months ended June 30, 2002 compared to
the same 2001 period. Total deliveries to retail customers decreased 5% in
the six months ended June 30, 2002 compared to the same 2001 period,
primarily as a result of slower economic conditions in 2002 offset by
increased customer growth.

Purchased Power and Fuel Expense
Purchased power and fuel expense for the six months ended June 30, 2002
increased $62 million as compared to the same 2001 period. The increase in fuel
and purchased power expense was primarily attributable to $150 million from
customers in Pennsylvania selecting or returning to PECO as their electric
generation supplier and higher PJM ancillary charges of $17 million. These
increases were partially offset by $63 million from lower gas prices, $30
million as a result of unfavorable weather conditions and $22 million primarily
attributable to lower delivery volume primarily related to gas.

Operating and Maintenance Expense
O&M expense for the six months ended June 30, 2002 increased $9
million, or 4%, as compared to the same 2001 period. The increase in O&M expense
was primarily attributable to $12 million related to the deployment of automated
meter reading technology and $9 million related to an increased allocation of
corporate expense. These increases were partially offset by $6 million of
incremental storm costs in 2001 and $4 million associated with a write-off of
excess and obsolete inventory in 2001.









92


Depreciation and Amortization Expense
Depreciation and amortization expense for the six months ended June 30,
2002 increased $21 million, or 11%, as compared to the same 2001 period. The
increase was primarily attributable to $17 million of additional amortization of
PECO's CTC and an increase of $4 million related to depreciation expense
associated with additional plant in service. The additional amortization of the
CTC is in accordance with PECO's original settlement under the Pennsylvania
Competition Act.

Taxes Other Than Income
Taxes other than income for the six months ended June 30, 2002
increased $38 million, or 45%, as compared to the same 2001 period. The increase
was primarily attributable to additional gross receipts tax related to
additional revenues and an increase in the gross receipts tax rate on electric
revenue effective January 1, 2002.

Interest Charges
Interest charges decreased $40 million, or 18% in the six months ended
June 30, 2002 as compared to the same 2001 period. The decrease was primarily
attributable to lower interest expense on long-term debt of $32 million as a
result of principal payments, lower interest rates and an $8 million reduction
in interest expense due to lower interest rates on a loan from ComEd in 2001.

Other Income and Deductions
Other income and deductions excluding interest charges decreased $16
million, or 89% in the six months ended June 30, 2002 as compared to the same
2001 period. The decrease in other income and deductions was primarily
attributable to lower interest income of $6 million in 2002. The decrease was
also attributable to a gain on the settlement of an interest rate swap of $6
million and the favorable settlement of a customer contract of $3 million, both
of which occurred in 2001.

Income Taxes
The effective tax rate was 33.2% for the six months ended June 30, 2002
as compared to 35.1% for the same 2001 period. The decrease in the effective tax
rate was primarily attributable to a reduction in state income taxes.

Preferred Stock Dividends
Preferred stock dividends for the quarter ended June 30, 2002 were
consistent as compared to the same 2001 period.

LIQUIDITY AND CAPITAL RESOURCES

PECO's business is capital intensive and requires considerable capital
resources. PECO's capital resources are primarily provided by internally
generated cash flows from operations and, to the extent necessary, external
financing including the issuance of commercial paper. PECO's access to external
financing at reasonable terms is dependent on its credit ratings and the general
business condition of PECO and the utility industry. Capital resources are used
primarily to fund construction, repayments of maturing debt and preferred
securities and


93


payment of common stock dividends to Exelon.

Cash Flows from Operating Activities
Cash flows provided by operations for the six months ended June 30,
2002 were $468 million compared to $427 million for the six months ended June
30, 2001. The increase in cash flows was primarily attributable to lower
payments related to accounts payable of $46 million, higher collection of
deferred energy costs as a result of a change in gas rates of $42 million and
lower prepaid taxes of $29 million. These increases were partially offset by
changes in intercompany receivables and payables of $41 million and deferred
income taxes of $32 million. PECO's cash flow from operating activities
primarily results from sales of electricity and gas to a stable and diverse base
of retail customers at fixed prices. PECO's future cash flows will depend upon
the ability to achieve cost savings in operations, and the impact of the
economy, weather and customer choice on its revenues. Although the amounts may
vary from period to period as a result of the uncertainties inherent in its
business, PECO expects that it will continue to provide a reliable and steady
source of internal cash flow from operations for the foreseeable future.

Cash Flows from Investing Activities
Cash flows used in investing activities for the six months ended June
30, 2002 were $122 million compared to $87 million for the six months ended June
30, 2001. The increase in cash flows used in investing activities was primarily
attributable to an increase in other investing activities. PECO's investing
activities during the six months ended June 30, 2002 were funded primarily by
operating activities.

PECO's projected capital expenditures for 2002 are $284 million.
Approximately one half of the budgeted 2002 expenditures are for capital
additions to support customer and load growth and the remainder for additions
and upgrades to existing facilities. PECO anticipates that it will obtain
financing, when necessary, through borrowings, the issuance of preferred
securities, or capital contributions from Exelon. PECO's proposed capital
expenditures and other investments are subject to periodic review and revision
to reflect changes in economic conditions and other factors.

Cash Flows from Financing Activities
Cash flows used in financing activities for the six months ended June
30, 2002 were $306 million compared to $332 million for the six months ended
June 30, 2001. Cash flows used in financing activities are primarily
attributable to debt service and payment of dividends to Exelon. The change in
cash flows used in financing activities is primarily attributable to an increase
in commercial paper borrowings of $196 million partially offset by additional
dividends paid to Exelon of $69 million, the contribution from Exelon in 2001 of
$53 million, additional debt service of $34 million, and proceeds from the
settlement of interest rate swap agreements in 2001 of $31 million.

Credit Issues
At June 30, 2002, PECO had outstanding $175 million of notes payable
consisting principally of commercial paper. Certain of the credit agreements to
which PECO is a party require PECO to maintain a debt to total capitalization
ratio of 65% or less, excluding



94


securitization debt and excluding the receivable from parent recorded in PECO's
shareholders' equity. At June 30, 2002, the debt to total capitalization ratios
on that basis for PECO was 38%.

PECO's access to the capital markets, including the commercial paper
market, and its financing costs in those markets are dependent on its securities
ratings. None of PECO's borrowings are subject to default or prepayment as a
result of a downgrading of securities ratings although such a downgrading could
increase interest charges under PECO's bank credit facility. PECO from time to
time enters into interest rate swaps that require the maintenance of investment
grade ratings. Failure to maintain investment grade ratings would allow the
counterparty to terminate the derivative and settle the transaction on a net
present value basis.

At June 30, 2002, PECO's capital structure, excluding the deduction
from shareholders' equity of the $1.8 billion receivable from Exelon, consisted
of 26% common equity, 2% notes payable, 3% preferred stock and COMRPS (which
comprised 2% of PECO's total capitalization structure), and 69% long-term debt
including transition bonds issued by PECO Energy Transition Trust (PETT).
Long-term debt included $4.4 billion of transition bonds representing 52% of
capitalization.

Under PUHCA and the Federal Power Act, PECO can pay dividends only from
retained or current earnings. At June 30, 2002, PECO had retained earnings of
$277 million.

Contractual Obligations and Commercial Commitments
Contractual obligations represent cash obligations that are considered
to be firm commitments and commercial commitments represent commitments
triggered by future events. PECO's contractual obligations and commercial
commitments as of June 30, 2002 were materially unchanged, other than in the
normal course of business, from the amounts as set forth in the December 31,
2001 Form 10-K except for an $85 million increase in the amount of surety bonds
required by PECO's insurance policies. Approximately one-fourth of the surety
bonds expire in the remainder of 2002 and the other three-fourths expire in the
two-year period ending December 2004.

Net Income
Generation's net income increased by $13 million, or 18%, for the three
months ended June 30, 2002 compared to the same period in the prior year. Net
income was positively impacted by increased revenue from affiliates, increased
revenue from the acquisition of two generating plants in April 2002 and reduced
depreciation and interest expense, partially offset by depressed wholesale
market prices for energy.

Operating Revenues, Net of Purchased Power and Fuel
Operating revenues, net of purchased power and fuel were $630 million
for the three months ended June 30, 2002 compared to $632 million for the same
period in 2001. The $2 million, or 0.3%, decrease was due to lower market prices
for energy, which reduced margins by $46 million during the three months ended
June 30, 2002 compared to the same period in 2001.


96


This decrease was partially offset by a $43 million increase in revenue from
affiliates, revenue from two generating plants acquired in April 2002, and lower
fuel costs. The average wholesale market prices were $7.00, or 18.6%, lower in
2002 compared to 2001. Generation's average purchased power costs for wholesale
operations were $39.96 per MWh for the three months ended June 30, 2002,
compared to $45.27 per MWh for the same period in 2001. The decrease in purchase
power costs resulted from the decrease in wholesale power market prices.
Additionally, revenue for the three months ended June 30, 2002 includes a net
trading portfolio loss of $16 million compared to a net $6 million loss for the
three months ended June 30, 2001.

For the three months ended June 30, 2002 and 2001, Generation's sales
and the supply of these sales excluding the trading portfolio, were as follows:

Generation's average margins on energy sales for the three months ended
June 30, 2002 and 2001 are as follows:

- ---------------------------------------------------------------------------------------------------------------------


Generation's nuclear fleet, including AmerGen, performed at a capacity
factor of 92.1% for the three months ended June 30, 2002 compared to 93.6% for
the same period in 2001.


97


Generation's nuclear fleet's production costs, including AmerGen, for the three
months ended June 30, 2002 were $12.54 per MWh compared to $13.02 per MWh for
the same period in 2001. The lower capacity factor is primarily due to 72
planned outage days in the three months ended June 30, 2002, versus 31 days in
the same period in 2001, including AmerGen. Reduced unit production costs
reflect additional generation due to power uprates and lower production costs
due to headcount reductions and Exelon's Cost Management Initiative in the three
months ended June 30, 2002 as compared to the same period in 2001.

Operating and Maintenance
Operating and maintenance expenses increased $6 million, or 2%, for the
three months ended June 30, 2002 compared to the same period in 2001. The
increase was primarily due to additional employee benefit costs of $9 million,
additional operating costs related to fossil plant outage work and the costs
related to the two generating plants acquired in April 2002 of $3 million. These
increases were partially offset by $7 million less in nuclear outage costs and
other operating cost reductions including savings from Exelon's Cost Management
Initiative.

Depreciation
Depreciation expenses decreased $10 million, or 13%, for the three
months ended June 30, 2002 compared to the same period in the prior year due to
a $16 million reduction in depreciation expense arising from the extension of
the useful lives on certain generation facilities in the third quarter of 2001,
partially offset by additional depreciation expense on capital additions placed
in service after June 30, 2001 including the acquisition of two generating
plants in April 2002.

Taxes Other Than Income
Taxes other than income increased $2 million, or 5%, for the three
months ended June 30, 2002 compared to the same period in the prior year
primarily due to an increase in property taxes.

Interest Expense
Interest expense decreased $15 million, or 58%, for the three months
ended June 30, 2002, compared to the same period in the prior year. The decrease
is primarily due to capitalized interest and a lower interest rate on the spent
nuclear fuel obligation.

Equity in Earnings of Unconsolidated Affiliates
Equity in earnings of unconsolidated affiliates decreased $4 million,
or 31%, for the three months ended June 30, 2002 compared to the same period in
the prior year. This decrease was due to a $7 million reduction in Generation's
equity earnings in AmerGen, primarily due to a planned plant outage, which began
in the first quarter of 2002. This decrease is partially offset by a $3 million
increase in Generation's equity earnings in Sithe.

Other, net
Other, net increased $10 million for the three months ended June 30,
2002 compared to the same period in the prior year primarily due to a $10
million increase in investment income from the nuclear decommissioning trust
funds.

Income Taxes
The effective income tax rate was unchanged at 37.7% for the three
months ended June 30, 2002 and 2001.

Net Income
Generation's net income decreased by $78 million, or 32%, for the six
months ended June 30, 2002 compared to the same period in 2001. Net income was
adversely impacted by a lower margin on wholesale energy sales due to depressed
market prices for energy, a reduced supply of low-cost nuclear generation, and
increased operating and maintenance expense partially offset by an increase in
revenue from affiliates and lower depreciation and interest expense.

Operating Revenues, Net of Purchased Power and Fuel
Operating revenues, net of purchased power and fuel were $1,264 million
for the six months ended June 30, 2002 compared to $1,442 million for the same
period in the prior year. The $178 million, or 12%, decrease was due to lower
wholesale market prices for energy, which reduced margins by $184 million, which
was partially offset by increased revenues from affiliates of $26 million and
lower fuel costs. The amount of low-cost nuclear generation



99


available for sale was reduced due to an increased number of nuclear generating
station refueling outages in the six months ended June 30, 2002, compared to the
same period in 2001. Additionally, trading activities were initiated in April
2001. Revenue for the six months ended June 30, 2002 includes a net trading
portfolio loss of $16 million compared to a net $6 million loss in the six
months ended June 30, 2001.

For the six months ended June 30, 2002 and 2001, Generation's sales and
the supply of these sales excluding the trading portfolio were as follows:

Trading volume was 22,805 GWhs and 454 GWhs for the six months ended
June 30, 2002 and 2001, respectively.

Generation's average margins on energy sales for the six months ended
June 30, 2002 and 2001 are as follows:

Generation's nuclear fleet, including AmerGen, performed at a capacity
factor 91.2% for the six months ended June 30, 2002 compared to 96.2% for the
same period in 2001. Generation's nuclear fleet's production costs, including
AmerGen, for the six months ended June 30, 2002 were $13.38 per MWh compared to
$12.34 per MWh for the same period in 2001. The lower capacity factor and
increased unit production costs are primarily due to 153 planned outage days in
the six months ended June 30, 2002, versus 31 days in the same period in 2001,



100


including AmerGen. Increased unit production costs are partially offset by lower
production costs due to headcount reductions and cost savings initiatives.
Generation's average purchased power costs for wholesale operations were $36.76
per MWh for the six months ended June 30, 2002, compared to $41.81 per MWh for
the same period in 2001. The decrease in purchase power costs was primarily due
to depressed wholesale power market prices.

Operating and Maintenance
Operating and maintenance expense increased $35 million, or 4%, for the
six months ended June 30, 2002 compared to the same period in 2001. This was due
to the additional operating and maintenance expense of $55 million arising from
an increased number of nuclear plant refueling outages during the six months
ended June 30, 2002 compared to the same period in 2001, as well as additional
allocated corporate costs including executive severance. These additional
expenses were offset by other operating cost reductions, including $10 million
related to headcount reductions, a $10 million reduction in Generation's
severance accrual and $4 million in savings from Exelon's Cost Management
Initiative. The severance reduction represents a reversal of costs previously
charged to operating expense.

Depreciation
Depreciation expenses decreased $39 million, or 23%, for the six months
ended June 30, 2002 compared to the same period in 2001 due to a $48 million
reduction in depreciation expense arising from the extension of the useful lives
on certain generation facilities commencing in the second quarter of 2001,
partially offset by additional depreciation expense on capital additions placed
in service after June 30, 2001, including the acquisition of two generating
plants in April 2002.

Taxes Other Than Income
Taxes other than income increased $5 million, or 6%, for the six months
ended June 30, 2002 compared to the same period in 2001 due primarily to the
Texas franchisee taxes related to the acquisition of two generating plants from
TXU in April 2002 and an increase in property taxes.

Interest Expense
Interest expense decreased $31 million, or 53%, for the six months
ended June 30, 2002, compared to the same period in 2001. The decrease is due to
capitalized interest and a lower interest rate on the spent nuclear fuel
obligation.

Equity in Earnings of Unconsolidated Affiliates
Equity in earnings of unconsolidated affiliates decreased $7 million,
or 18%, for the six months ended June 30, 2002 compared to the same period in
2001. This decrease was due to a $12 million reduction in Generation's equity
earnings in AmerGen, primarily due to a planned plant outage in 2002. This
decrease is partially offset by an increase of $5 million in Generation's equity
earnings of Sithe.




101


Other, net
Other, net increased $22 million, or 122%, for the six months ended
June 30, 2002 compared to the same period in 2001, primarily due to a $22
million increase in investment income from the nuclear decommissioning trust
funds.

Income Taxes
The effective income tax rate was substantially unchanged at 39.0% for
the six months ended June 30, 2002 compared to 39.6% for the same period in
2001.

Cumulative Effect of Changes in Accounting Principles
On January 1, 2002, Generation adopted SFAS No. 141 resulting in a
benefit of $13 million (net of income taxes of $9 million).

On January 1, 2001, Generation adopted SFAS No. 133, as amended,
resulting in a benefit of $12 million (net of income taxes of $7 million).


LIQUIDITY AND CAPITAL RESOURCES

Generation's business is capital intensive and requires considerable
capital resources. Generation's capital resources are primarily provided by
internally generated cash flows from operations and, to the extent necessary,
external financings and borrowings or capital contributions from Exelon.
Generation's access to external financing at reasonable terms is dependent on
Generation's credit ratings and general business condition, as well as the
general business conditions of the industry. Capital resources are used
primarily to fund capital requirements, including construction, investments in
new and existing ventures, and repayments of maturing debt. Any potential future
acquisitions could require external financing or borrowings or capital
contributions for Exelon.

Cash Flows from Operating Activities
Cash flows provided by operations were $519 million for the six months
ended June 30, 2002, compared to $485 million for the same period in 2001.
Generation's cash flows from operating activities primarily result from the sale
of electric energy to wholesale customers, including Generation's affiliated
companies, as well as settlements arising from Generation's trading activities.
Generation's future cash flow from operating activities will depend upon future
demand and market prices for energy and the ability to continue to produce and
supply power at competitive costs.

Cash Flows from Investing Activities
Cash flows used in investing activities were $1,048 million for the six
months ended June 30, 2002, compared to $99 million for the same period in 2001.
Capital expenditures were $258 million and the investment in nuclear fuel was
$217 million in the six months ended June 30, 2002 compared to capital
expenditures of $173 million and investment in nuclear fuel of $128 million in
the same period in 2001. In addition to the 2002 capital expenditures,
Generation closed the purchase of two natural-gas and oil-fired plants from TXU
on April 25, 2002. The $443 million purchase was funded with available cash and
borrowings from Exelon. An increased number of


102


nuclear generating station refueling outages occurred during the six months
ended June 30, 2002 compared to the same period in 2001. Generation's investing
activities were funded from operating activities, borrowings from Exelon and the
use of available cash.

In February 2002, Generation entered into an agreement to loan AmerGen
up to $75 million at an interest rate of one-month LIBOR plus 2.25%. As of June
30, 2002, AmerGen had borrowed $75 million under this agreement. In July 2002,
the loan agreement and the loan were increased to $100 million and the maturity
date was extended to July 1, 2003.

Cash Flows from Financing Activities
Cash flows provided by financing activities were $329 million for the
six months ended June 30, 2002, compared to cash used of $67 million for the
same period in the prior year. In 2002 Generation obtained a $331 million loan
from Exelon for the acquisition of two generating plants. The prior year amount
represented net distributions of $121 million to Exelon and the issuance of
long-term debt of $752 million. Also, in 2001 Generation repaid $696 million it
had borrowed from Exelon related to the acquisition of a 49.9% interest in
Sithe.

Credit Issues
Generation meets its short-term liquidity requirements primarily
through borrowings under bank credit facilities and borrowings from the Exelon
intercompany utility money pool. Generation, along with Exelon, ComEd and PECO
entered into a $1.5 billion unsecured 364-day revolving credit facility on
December 12, 2001 with a group of banks. As of June 30, 2002, no borrowing
sublimit had been established for Generation under this credit facility. This
credit facility requires Generation to maintain a debt to total capitalization
ratio of 65% or less. At June 30, 2002, Generation's debt to total
capitalization ratio was 32%.

Generation's access to the capital markets and its financing costs in
those markets are dependent on its securities ratings. None of Generation's
borrowings are subject to default or prepayment as a result of a downgrading of
securities ratings although such a downgrading could increase interest charges
under certain bank credit facilities.

From time to time Generation enters into interest rate swap and other
derivatives that require the maintenance of investment grade ratings. Failure to
maintain investment grade ratings would allow the counterparty to terminate the
derivative and settle the transaction on a net present value basis.

Under PUHCA and the Federal Power Act, Generation can only pay
dividends from undistributed or current earnings. At June 30, 2002, Generation
had undistributed earnings of $686 million.

Contractual Obligations and Commercial Commitments
Contractual obligations represent cash obligations that are considered
to be firm commitments and commercial commitments represent commitments
triggered by future events. Generation's contractual obligations and commercial
commitments as of June 30, 2002 were materially unchanged, other than in the
normal course of business, from the amounts set forth in the December 31, 2001
Form10-K except for the following:


103


o On April 25, 2002 Generation closed the purchase of two generating plants
from TXU. The $443 million purchase was funded primarily with borrowings
from Exelon.
o On June 26, 2002 Generation agreed to purchase Sithe New England for $543
million plus the assumption of non-recourse debt estimated to be
approximately $1.2 billion at the date of purchase. The purchase is
estimated to close in November 2002, subject to regulatory approval. See
Note 3 of the Combined Notes to the Consolidated Financial Statements for
additional information about the Sithe New England acquisition.
o Purchase obligations increased by $1.2 billion, primarily due to an
increase of $2.0 billion in power only purchases partially offset by a $0.8
billion decrease in net capacity purchase commitments. The increase in
power only purchases is primarily due to Generation's agreement to purchase
all the energy from Unit No. 1 at Three Mile Island after December 31, 2001
through December 31, 2014. This decrease in net capacity purchase
commitments is due primarily to the decision not to exercise the option to
purchase 2,684 MWs of capacity from Midwest Generation in 2002 and 2003 as
well as the increase in capacity sales under the TXU tolling agreement.

Off Balance Sheet Obligations
Generation owns 49.9% of the outstanding common stock of Sithe and has
an option, beginning on December 18, 2002, to purchase the remaining common
stock outstanding (Remaining Interest) in Sithe. The purchase option expires on
December 18, 2005. In addition, the Sithe stockholders who own in the aggregate
the Remaining Interest have the right to require Generation to purchase the
Remaining Interest (Put Rights) during the same period in which Generation can
exercise its purchase option. At the end of this exercise period, if Generation
has not exercised its purchase option and the other Sithe stockholders have not
exercised their Put Rights, Generation will have an additional one-time option
to purchase shares from the other stockholders in Sithe to bring Generation's
ownership in Sithe from the current 49.9% to 50.1% of Sithe's total outstanding
common stock.

If Generation exercises its option to acquire the Remaining Interest,
or if all the other Sithe stockholders exercise their Put Rights, the purchase
price for 70% of the Remaining Interest will be set at fair market value subject
to a floor of $430 million and a ceiling of $650 million. The balance of the
Remaining Interest will be valued at fair market value subject to a floor of
$141 million and a ceiling of $330 million. In either instance, the floor and
ceiling will accrue interest from the beginning of the exercise period.

If Generation increases its ownership in Sithe to 50.1% or more, Sithe
will become a consolidated subsidiary and Exelon's financial results will
include Sithe's financial results from the date of purchase. At June 30, 2002,
Sithe had total assets of $4.1 billion and total debt of $2.1 billion, including
$1.6 billion of non-recourse project debt of which $1.0 billion is associated
with Sithe New England, $0.4 billion of subordinated debt, $49 million of
short-term debt, $33 million of capital leases, and excluding $411 million of
non-recourse project debt associated with Sithe's equity investments. For the
six months ended June 30, 2002, Sithe had revenues of $0.6 billion. As of June
30, 2002, Generation had a $725 million equity investment in Sithe. On June 26,
2002, Generation agreed to purchase Sithe New England for $543 million plus the
assumption of approximately $1.2 billion of non-recourse project debt, which is



104


expected to be outstanding at the time of the closing of the purchase.
Generation expects to close the purchase of Sithe New England in November 2002,
subject to regulatory approval.

Additionally, the debt on the books of Exelon's unconsolidated equity
investments and joint ventures is not reflected on Exelon's Consolidated Balance
Sheets. Total investee debt, at June 30, 2002 including the debt of Sithe
described in the preceding paragraph, is currently estimated to be $2.3 billion
($1.2 billion based on Exelon's ownership interest of the investments).

Generation and British Energy, Generation's joint venture partner in
AmerGen, have each agreed to provide up to $100 million to AmerGen at any time
for operating expenses.

Other Factors
Generation is a counterparty to Dynegy in various energy transactions.
In early July 2002, the credit ratings of Dynegy were downgraded by two credit
rating agencies to below investment grade. As of July 29, 2002, Generation had a
net receivable from Dynegy of less than $5 million, and consistent with the
terms of the existing credit arrangement, has requested collateral in support of
this receivable. Generation also has credit risk associated with Dynegy through
Generation's equity investment in Sithe. Sithe is a 60% owner of the
Independence generating station, a 1,040 MW gas-fired qualified facility that
has an energy only long-term tolling arrangement with Dynegy, with a related
financial swap arrangement. As of June 30, 2002, Sithe had recognized an asset
on its balance sheet related to the fair value of the financial swap agreement
with Dynegy that is marked-to-market under the terms of SFAS No. 133. If Dynegy
is unable to fulfill the terms of this agreement, Sithe would be required to
write-off the fair value asset, which Generation estimates would result in an
approximate $15 million reduction in its equity earnings from Sithe, based on
Generation's current 49.9% investment ownership in Sithe. Additionally, the
future economic value of Sithe's investment in the Independence Station and
AmerGen's purchased power arrangement with Illinois Power, a subsidiary of
Dynegy, could be impacted by events related to Dynergy's financial condition.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Commodity Price Risk
Generation
Generation's energy contracts are accounted for under SFAS No. 133.
Most non-trading contracts qualify for a normal purchases and normal sales
exception. Those that do not are recorded as assets or liabilities on the
balance sheet at fair value. Changes in the fair value of qualifying cash-flow
hedge contracts are recorded in accumulated other comprehensive income, and
gains and losses are recognized in earnings when the underlying transaction
matures. Mark-to-market gains and losses on other derivative contracts that do
not meet hedge criteria under SFAS No. 133 and the ineffective portion of hedge
contracts are recognized in earnings on a current basis. Amounts recognized in
earnings related to energy contracts for the three months ended June 30, 2002
and 2001 include $17 million of realized gains from cash-flow hedge contract
settlements and $5 million in non-cash mark-to-market losses on other derivative
contracts, and for the six months ended June 30, 2002 include $54 million of
realized gains from cash-flow hedge contract settlements and $2 million in
non-cash mark-to market losses on other derivative contracts.

Outlined below is a summary of the changes in fair value for those
contracts included as assets and liabilities in Exelon and Generation's
Consolidated Balance Sheet for the three months and six months ended June 30,
2002:

The majority of Generation's contracts are non-exchange traded
contracts valued using prices provided by external sources, which primarily
represent price quotations available through brokers or over-the-counter,
on-line exchanges. Prices reflect the average of the bid-ask midpoint prices
obtained from all sources that Generation believes provide the most liquid
market for the commodity. The terms for which such price information is
available varies by commodity, by region and by product. The remainder of the
assets represent contracts for which external valuations are not available,
primarily option contracts. These contracts are valued using the Black model, an
industry standard option valuation model, and other valuation techniques and are
discounted using a risk-free interest rate. The fair values in each category
reflect the level of forward prices and volatility factors as of June 30, 2002
and may change as a result of future changes in these factors.










107


Mark-to market gains and losses on qualifying cash-flow hedge contracts
are recorded in accumulated other comprehensive income, and will be reclassified
into earnings when the contract settles. Mark-to-market gains and losses on
derivative contracts that do not meet hedge criteria under SFAS No. 133 and the
ineffective portion of hedge contracts have been recognized in earnings on a
current basis. The maturities, or expected settlement dates, of the qualifying
cash flow hedge contracts recorded in accumulated other comprehensive income,
and the other non-trading and trading derivative contracts and sources of fair
value as of June 30, 2002 are as follows:

Credit Risk
Exelon and Generation

Generation is a counterparty to Dynegy in various energy transactions.
In early July 2002, the credit ratings of Dynegy were downgraded by two credit
rating agencies to below investment grade. As of July 29, 2002, Generation had a
net receivable from Dynegy of less than $5 million, and consistent with the
terms of the existing credit arrangement, has requested collateral in support of
this receivable. Generation also has credit risk associated with Dynegy through
Generation's equity investment in Sithe. Sithe is a 60% owner of the
Independence generating station, a 1,040 MW gas-fired qualified facility that
has an energy only long-term tolling arrangement with Dynegy, with a related
financial swap arrangement. As of June 30, 2002, Sithe had recognized an asset
on its balance sheet related to the fair value of the financial swap agreement
with Dynegy that is marked-to-market under the terms of SFAS No. 133. If Dynegy
is unable to fulfill the terms of this agreement, Sithe would be required to
write-off the fair value asset, which Generation estimates would result in an
approximate $15 million reduction in its equity earnings from Sithe, based on
Generation's current 49.9% investment ownership in Sithe. Additionally, the
future economic value of Sithe's investment in the Independence Station and
AmerGen's


108


purchased power arrangement with Illinois Power, a subsidiary of Dynegy, could
be impacted by events related to Dynergy's financial condition.

PART II - OTHER INFORMATION


ITEM 1. LEGAL PROCEEDINGS

As previously reported in Exelon's March 2002 Form 10-Q, on May 8,
2002, a class action lawsuit was filed against Exelon on behalf of purchasers of
Exelon securities between April 24, 2001 and September 27, 2001 (Class Period).
The lawsuit was filed in the United States District Court for the Northern
District of Illinois, Eastern Division. The complaint alleges that Exelon
violated Federal securities laws by issuing a series of materially false and
misleading statements relating to its 2001 earnings expectations during the
Class Period. Corbin A. McNeill, Jr., John Rowe and Ruth Ann Gillis were also
named as defendants. Between May 8 and June 14, 2002, an additional five nearly
identical class actions lawsuits were filed. On May 30 and July 2, 2002, the
Court consolidated the cases into one lawsuit. Exelon believes that the lawsuit
is without merit and will vigorously contest this matter.

As previously reported in the 2001 Form 10-K and the March 2002 Form
10-Q, several developers of non-utility generating facilities filed litigation
against various Illinois officials claiming that the enforcement of an Illinois
law amendment, which removed the entitlement of those facilities to receive
state-subsidized payments for electricity sold to ComEd after March 15, 1996,
violated their rights under the Federal and state constitutions. Subsequently,
the developers filed complaints alleging that ComEd breached the contracts in
question and requested damages reflecting the state-subsidized rate to which the
developers claim they were entitled under their contracts. In July 2002, certain
of the plaintiffs produced an expert report claiming approximately $175 million
in damages, a quantification ComEd vigorously disputes. Virtually all parties
have filed motions for summary judgment. ComEd is contesting each case and has
filed its motion for summary judgment arguing that, as a matter of law, it did
not breach any of the contracts.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

Information regarding the submission of matters to a vote of security
holders is presented in the Form 10-Q for the Quarterly period ended March 31,
2002.

ITEM 5. OTHER INFORMATION


ComEd
On May 28, 2002, ComEd filed a declaration with the FERC to join PJM.
ComEd committed to place its transmission system under the control of an
independent transmission company that would operate within PJM West, which would
be managed by National Grid USA and would also include the transmission systems
of American Electric Power East and Illinois Power.


110


On July 19, 2002, ComEd filed a request with the ICC to revise the POLR
obligation in Illinois. ComEd is seeking permission from the ICC to limit the
availability by June 2006 of Rate 6L for 370 of ComEd's largest energy customers
with demands of at least three MWs, totaling approximately 2,500 MWs. Rate 6L is
a bundled fixed rate offered to large customers including heavy industrial
plants, large office buildings, government facilities and a variety of other
businesses. The ICC has 120 days to act on the filing or it will be deemed
approved.

On August 1, 2002, ComEd set a new record for highest peak load
experienced to date of 21,852 MWs.

PECO
As previously disclosed in the 2001 Form 10-K, in February 2002, New
Power notified PECO of its intent to withdraw from providing Competitive Default
Service ("CDS") to approximately 180,000 residential customers. As a result of
that withdrawal, those CDS customers were returned to PECO in the second quarter
of 2002. Pursuant to a tariff filing approved by the Pennsylvania Public Utility
Commission, PECO will serve those returned customers at the discount energy
rates on generation provided for under the original New Power CDS Agreement for
the remaining term of that contract. Subsequently, in the second quarter of
2002, New Power also advised PECO it planned to withdraw from serving all of its
customers in Pennsylvania, including approximately 15,000 non-CDS PECO
customers, and to return those customers to PECO in September 2002.

On July 29, 2002, PECO set a new record for highest peak load
experienced to date of 8,193 MWs.

Generation

On April 25, 2002, Generation completed the purchase of two TXU Energy
power plants located in Dallas and Fort Worth areas for 443 million. The
agreement was first announced in December 2001. The purchase includes the 893 MW
Mountain Creek Steam Electric Station in Dallas and the 1,441 MW Handley Steam
