               Exelon Announces Second Quarter Operating Earnings
                   of $1.14 Before Gain on Sale of Investment

Chicago (July 31, 2002) - Exelon Corporation (NYSE: EXC) today reported
consolidated earnings of $485 million, or $1.50 per share (diluted), for the
second quarter of 2002. Operating earnings were $369 million, or $1.14 per
share, before a $116 million, or $0.36 per share, after-tax gain related to
Exelon Enterprises' sale of its 49% interest in AT&T Wireless PCS of
Philadelphia. The transaction closed on April 1, 2002. Operating earnings in the
second quarter of 2002 were up 18% compared with second quarter 2001 earnings of
$0.97 per share.

Improved operating results were due to increased weather related kWh deliveries,
lower interest expense and lower operating and maintenance expense in the
quarter compared to second quarter 2001. The Cost Management Initiative achieved
$93 million of savings in the second quarter and $104 million year-to-date. The
estimated net impact of favorable weather is $0.09 per share in the second
quarter compared to the prior year and also $0.09 per share relative to the
normal weather that was incorporated in Exelon's guidance. The cessation of
goodwill amortization contributed $0.12 per share for the quarter relative to
the second quarter of 2001.

John W. Rowe, Exelon Chairman and CEO, stated, "Our strong second quarter
earnings are the result of the efforts of Exelon employees to live up to our
commitments and perform at world-class levels. Our Cost Management Initiative,
led by Oliver Kingsley, is producing results. Based on everything we know today,
we expect to meet or exceed the current consensus estimate of $4.65 per share.
However, with the current economic and wholesale power price volatility, it is
difficult to project earnings in a narrow range."

2002 Earnings Outlook

Exelon's 2002 earnings outlook has been updated to incorporate year-to-date
events including first half operating results and our expectations for the
balance of the year. Exelon's guidance for consolidated 2002 earnings from
operations excluding unusual items remains in the range of $4.55 to $4.85 per
diluted share based on the assumption of normal weather for the balance of the
year. Earnings from operations exclude the second quarter gain from the sale of
the AT&T investment and first quarter goodwill impairment and severance costs.
Third quarter earnings are expected to represent about 30% of the full year
earnings.

Second Quarter Highlights

o    Exelon Generation's nuclear group completed two scheduled refueling outages
     during the second quarter of 2002, the same as in the second quarter of
     2001. The average refueling outage duration for the first half of 2002 was
     23 days compared to 25 days for the first half of 2001. In the second
     quarter of 2002, there was a planned maintenance outage (non-refueling
     outage) at LaSalle Station with a duration of 15 days. Power uprate
     modifications were installed during both of the second quarter 2002
     refueling outages, adding a total of 129 MWs of additional capacity. Exelon
     Generation's nuclear fleet, excluding AmerGen, produced 28,353 GWhs output
     for the second quarter of 2002, compared to 28,443 GWhs output for the
     second quarter of 2001. The fleet, including AmerGen, achieved a capacity
     factor of 92.1% for the second quarter of 2002, compared to 93.6% for the
     second quarter 2001.

o    Exelon Generation's fossil operations continued their strong performance in
     the second quarter with 98.9% on-time delivery and 94.2% dispatch
     availability.

o    Exelon Generation's power marketing organization, Power Team, mitigated the
     impact of depressed wholesale power prices during the second quarter with
     hedging activities. The average realized wholesale market price, excluding
     trading, for the quarter was $31/MWh, significantly higher than the average
     observed around-the-clock spot price of approximately $25/MWh in its two
     primary generation supply regions of MAIN and PJM. The average realized
     market price, excluding trading, in second quarter of 2001 was $38/MWh.

o    On April 25, 2002, Exelon Generation acquired two natural-gas and oil-fired
     plants from TXU Corp. (TXU) for an aggregate purchase price of $443
     million. The purchase includes the 893-megawatt Mountain Creek Steam
     Electric Station in Dallas and the 1,441-megawatt Handley Steam Electric
     Station in Fort Worth.

o    Exelon Enterprises completed the sale of its 49% interest in AT&T Wireless
     PCS of Philadelphia, LLC to a subsidiary of AT&T Wireless Services for $285
     million in cash. The transaction closed on April 1, 2002. The after-tax
     gain was $116 million with a resulting $0.36 earnings per share (diluted)
     gain included in reported earnings for the quarter but excluded from
     operating income.

o    On June 27, Exelon Generation announced an agreement to purchase Sithe New
     England Holdings, a subsidiary of Sithe Energies, Inc., in exchange for a
     $543 million note, plus the assumption of approximately $1.15 billion of
     project debt. If the transaction closing conditions are met and Federal
     Energy Regulatory Commission (FERC) and other approvals are received, the
     transaction could be completed in November 2002.

o    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.

o    On July 19, Exelon Energy Delivery's Illinois operating company, ComEd,
     filed a request with the Illinois Commerce Commission (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 its largest energy customers, those with demands of at least 3
     megawatts, which typically include heavy industrial plants, large office
     buildings, government facilities and a variety of other businesses. Rate 6L
     is a bundled fixed rate offered to about 370 customers representing 2,500
     MWs of load. The ICC has 120 days to act on the filing or it will be deemed
     approved.

Other items:

Exelon early adopted new accounting guidance issued by the Emerging Issues Task
Force of the Financial Accounting Standards Board (EITF 02-3) in June, which
requires that revenues and expenses related to energy trading contracts be
presented on a net basis in the income statement. Prior to the second quarter of
2002, Exelon's trading revenues and costs were presented on a gross basis. For
comparative purposes, page 14 of the attachment provides the impact of netting
trading expenses with revenues for prior quarters.


BUSINESS UNIT RESULTS
Exelon Corporation's consolidated net income for the second quarter of 2002 was
$485 million compared with net income of $315 million in the second quarter of
2001.

Exelon Energy Delivery consists of the retail electricity transmission and
distribution operations of ComEd and PECO Energy and the natural gas
distribution business of PECO Energy. Energy Delivery's net income in the second
quarter of 2002 was $322 million compared with net income of $264 million in the
second quarter of 2001, primarily due to cost savings and increased
weather-related kWh sales in 2002.

Cooling degree days in the ComEd service territory were up 29% relative to last
year and 33% above normal. In the PECO service territory cooling degree days
were up 1% compared with 2001 and 36% above normal. Total retail KWh deliveries
rose 2.2% for ComEd, with a 12% increase in deliveries to the weather-sensitive
residential customer class. PECO's retail KWh deliveries increased 3.0% overall.
Energy Delivery's total revenues for the second quarter of 2002 of $2,476
million were up 2% from $2,436 million in 2001, offset by a $31 million net
increase in fuel and purchased power. Operating and maintenance expense
decreased $23 million reflecting lower uncollectable accounts expense and Cost
Management Initiative savings. The absence of the amortization of goodwill and
lower interest expense contributed to the increase in Energy Delivery's
operating results. The impact of the warmer summer weather increased Energy
Delivery's second quarter 2002 earnings per share (diluted) by approximately
$0.05 relative to 2001 and $0.06 relative to the normal weather that was
incorporated in our earnings guidance.

Exelon Generation consists of Exelon's electric generation operations and power
marketing and trading functions. Generation's second quarter 2002 net income of
$84 million was up from second quarter 2001 net income of $71 million. The
increase is due to the positive impacts of Exelon's Cost Management Initiative,
lower interest expense and lower depreciation expense, partially offset by
higher trading portfolio losses. Energy sales for the second quarter of 2002
totaled 50,238 GWhs, exclusive of trading volumes, compared with 48,068 GWhs in
2001. Generation's second quarter 2002 revenue of $1,559 million includes a net
trading portfolio loss of $16 million compared to second quarter 2001 revenue of
$1,583 million, which includes a net trading portfolio loss of $6 million. As
noted above, second quarter 2001 revenues have been revised to reflect the
adoption of EITF 02-3, which requires that trading-related expenses be netted
against trading revenues. Revenues, excluding the net trading portfolio losses,
decreased 2.2% from the second quarter of 2001, reflecting lower market prices
for energy.

The average realized price excluding trading activity in the second quarter of
2002 was $31 per MWh compared with $33 per MWh in 2001. The average realized
price reflects a higher proportion ot Generation's total sales being to Exelon
Energy Delivery as a result of favorable weather conditions, which partially
offset the impact of lower market prices during the second quarter of 2002 as
compared to the second quarter of 2001. Revenue net fuel decreased $2 million to
$630 million for the second quarter of 2002 as compared to the second quarter of
2001 as a result of the factors noted above. The second quarter 2002 revenue net
fuel includes net mark-to-market losses of $5 million including non-cash
mark-to-market gains on non-trading activities of $4 million and non-cash
mark-to-market trading losses of $9 million. Operating and maintenance expenses
increased $6 million reflecting the addition of the plants acquired from TXU,
which are offset by savings generated by Exelon's Cost Management Initiative
efforts. Depreciation and amortization decreased $10 million for the second
quarter of 2002 as compared to the second quarter of 2001 due primarily to plant
life extensions, which were incorporated in the depreciation calculation
beginning in the latter half of 2001. Interest expense of $11 million was $15
million lower for the second quarter of 2002 as compared to the second quarter
of 2001 due primarily to lower interest rates on borrowings and higher
capitalized interest.

Exelon Enterprises consists of Exelon's competitive retail energy sales, Energy
Solutions and infrastructure services, venture capital investments and related
businesses. Enterprises reported second quarter 2002 net income of $83 million,
which includes the $116 million after-tax gain on the sale of the AT&T Wireless
investment. Excluding that gain, second quarter 2002 results were a loss of $33
million. Second quarter 2001 results were a loss of $5 million. Enterprises
second quarter 2001 results included an $18 million gain on investments. The $28
million decrease in 2002 earnings compared to 2001 is primarily due to $36
million of investment writedowns and $4 million of other net asset writedowns in
the second quarter of 2002, partially offset by the cessation of goodwill
amortization, lower interest expense and the absence of AT&T Wireless operating
losses after the April sale. Enterprises revenues and operating expenses were
each lower by approximately $70 million compared to 2001, as a result of reduced
project activity at Energy Solutions, reduced construction activity at
InfraSource due to the continued decline in the telecommunications industry,
reduced gas prices, and Enterprises' unregulated Exelon Energy's exit from the
retail energy business in the PJM region, partially offset by higher electric
revenues from the Illinois energy market.

2002 Earnings per Diluted Share                                    $ 1.50
                                                                =========

(1)  Realized gains on distributions on Enterprises investments.

(2)  Primarily reflects higher PJM ancillary costs, lower margins on energy
     trading activity and rate reductions at EED, partially offset by a stronger
     economy in Chicago in 2002 compared to 2001. ComEd's 5% residential
     customer rate reflects a reduction of $0.05 per share.

(3)  Primarily related to warmer summer weather in the second quarter of 2002
     compared to 2001. Additionally, because retail electricity sales were up
     due to weather, the Power Team sold less electricity at wholesale prices.
     The estimated net impact of weather is an increase to earnings per share of
     $0.05, $0.02 and $0.02 at Energy Delivery, Generation and Enterprises,
     respectively.

(4)  Reflects $36 million of investment write-downs and $4 million of net asset
     writedowns at Enterprises.

(5)  Lower O&M's primarily relate to decreased Generation O&M's, offset by
     increased Energy Delivery O&M's reflecting uncollectible accounts and
     claims expenses and costs associated with the deployment of automatic meter
     reading technology. Reductions in InfraSource and Exelon Services O&M's
     resulting from lower business activity of $51 million is excluded from this
     effect. The earnings effect of lower InfraSource and Exelon Services O&M's
     is offset by lower nfraSource and Exelon Services revenue.

(6)  Reflects lower debt outstanding and lower interest rates due to refinancing
     at Energy Delivery and a lower rate on Generation's spent nuclear fuel
     obligation.

(7)  Primarily reflects a higher gross receipts tax rate at PECO.

(8)  Depreciation and amortization expense, excluding goodwill amortization, was
     higher primarily related to the effect of increased CTC amortization at
     PECO and increased depreciation related to higher depreciable plant
     partially offset by the extension of the estimated service lives of the
     generating stations in 2001.

(9)  Primarily relates to lower state income tax rates.

(1)  Realized gains on distributions on Enterprises investments.

(2)  Primarily reflects lower market prices for energy, PJM ancillary costs,
     margins on energy trading activity and rate reductions at EED, partially
     offset by a stronger economy in Chicago in 2002 compared to 2001. ComEd's
     5% residential customer rate reflects a reduction of $0.10 per share.

(3)  Primarily related to warmer winter weather in Chicago and Philadelphia,
     offset by warmer summer weather in Chicago in 2002 compared to 2001.

(4)  Relates to five nuclear refueling outages in 2002 as compared to two
     refueling outages in 2001.

(5)  Reflects $38 million of investment write-downs and $4 million of net asset
     write-downs at Enterprises.

(6)  Lower O&M's, excluding outage costs, severance costs and lower InfraSource
     and Exelon Services activity, primarily relate to Exelon's Cost Management
     Initiative and decreased Generation O&M's.

(7)  Reflects lower debt outstanding and lower interest rates due to refinancing
     at Energy Delivery and a lower rate on Generation's spent nuclear fuel
     obligation.

(8)  Primarily reflects a higher gross receipts tax rate at PECO.

(9)  Depreciation and amortization expense, excluding goodwill amortization, was
     lower primarily related to the effect of the extension of the estimated
     service lives of the generating stations in 2001, partially offset by
     increased CTC amortization at PECO, higher amortization of capitalized
     software at Enterprises and increased depreciation related to higher
     depreciable plant.

(10) Primarily relates to lower state income tax rates.

(11) Executive severance costs partially offset by favorable adjustments to
     previous severance estimates. A portion of the executive severance is not
     tax deductible. As a result, the after-tax impact on earnings is $0.04 per
     share.

     cost of the transmission and distribution of the energy. PECO's tariffed
     rates also include a CTC charge.

(b)  Unbundled service reflects customers electing to receive electric
     generation service under the ComEd PPO option or an alternative energy
     supplier. Revenue from customers choosing the ComEd PPO option includes an
     energy charge at market rates, transmission and distribution charge and a
     CTC charge. Revenue from customers choosing an alternative energy supplier
     includes a distribution charge and a CTC charge. Transmission charges
     received from alternative energy suppliers are included in wholesale and
     miscellaneous revenue.

     their supplier of electricity, however, as of June 30, 2002, no alternative
     electric supplier has sought approval from the Illinois Commerce Commission
     (ICC) and no electric utilities have chosen to enter the ComEd residential
     market for the supply of electricity.
