                 Exelon Announces Strong First Quarter Earnings;
                        Reaffirms 2003 Earnings Guidance

Chicago (April 28, 2003) - Exelon Corporation (NYSE: EXC) today announced
operating earnings for the first quarter of 2003 of $397 million, or $1.22 per
share (diluted), compared with operating earnings of $250 million, or $0.77 per
share (diluted), for the same period in 2002. The 58% improvement year-over-year
was due primarily to higher weather-related gas and kWh sales, increased CTC
revenue at ComEd, lower depreciation and amortization expense, fewer nuclear
outages and lower interest expense, which more than offset increased operating
expenses including pension and benefit costs.

Reported first quarter 2003 consolidated earnings prepared in accordance with
accounting principles generally accepted in the United States (GAAP) were $361
million, or $1.11 per share (diluted). Reported results for the first quarter
include the $112 million, or $0.34 per share, after-tax gain for the cumulative
effect of adopting SFAS 143, "Accounting for Asset Retirement Obligations."
Reported earnings also include a $17 million, or $0.05 per share, after-tax
charge related to the March 3 ComEd Settlement Agreement discussed below and an
after-tax charge for the impairment of Exelon's investment in Sithe Energies,
Inc. of $130 million, or $0.40 per share. Reported earnings in the first quarter
of 2002 were $8 million, or $0.02 per share (diluted), which included a $230
million, or $0.71 per share, after-tax charge for the cumulative effect of
adopting SFAS 142, an accounting standard for goodwill and intangible assets,
and net pre-tax charges of $10 million, or $0.04 per share, for severance costs.
(Details on the differences between GAAP earnings and operating earnings are
included below, with a tabular reconciliation of these differences included in
the attachments to this release.)

"Our first quarter results provide a solid base to build on in 2003," said John
W. Rowe, Exelon Chairman and CEO. "Through The Exelon Way, we will continue to
improve efficiency and productivity and create even more value for our
investors. We believe The Exelon Way will enable us to meet or exceed 5% annual
earnings growth and provide cash that will increase balance sheet flexibility to
successfully handle the end of the regulatory transition in Illinois in 2007."


2003 Earnings Guidance

Exelon's full year operating earnings are expected to fall within a range of
$4.80 to $5.00 per share. The earnings guidance is based on the assumption of
normal weather for the last three quarters of 2003 and excludes the first
quarter $0.34 per share cumulative effect for the change in accounting
principle, the net $0.05 per share charge related to the March 3 ComEd
settlement agreement and the $0.40 per share impairment of our Sithe Energies
investment. Second quarter operating earnings are expected to represent between
21% and 23% of full year operating earnings.

Adoption of SFAS 143

Exelon adopted SFAS 143 as of January 1, 2003. SFAS 143 provides accounting
requirements for retirement obligations associated with tangible long-lived
assets. The new standard changed the accounting for decommissioning of nuclear
generating plants as well as certain other long-lived assets. Adoption of the
new standard resulted in $112 million of after-tax income reported as a
cumulative effect of a change in accounting principle in the first quarter of
2003. The new standard is not expected to have an impact on ongoing earnings.

Operating Earnings

Operating earnings (pro forma), which generally exclude non-operational items as
well as one-time charges or credits that are not normally associated with our
ongoing operations, are provided as a complement to results provided in
accordance with GAAP. Management uses such pro forma measures internally to
evaluate the company's performance and manage its operations. A reconciliation
of GAAP to operating earnings is included in the attachments to this release.
Operating earnings (pro forma) exclude:

o    Cumulative effect of changes in accounting principles
o    One-time gains (losses) associated with a regulatory order
o    Severance charges or other costs associated with  restructuring  operations
     that are material in magnitude
o    Transaction-related  gains or losses  related to the sale or purchase of an
     asset or business, which is not a part of ongoing operations.


First Quarter Highlights

o        Nuclear Operations Exelon Generation's nuclear fleet, excluding
         AmerGen, produced 29,330 GWhs for the first quarter of 2003, compared
         with 27,533 (reflects reallocation) GWhs output for the first quarter
         of 2002. The fleet, including AmerGen, achieved a capacity factor of
         94.4% for the first quarter of 2003, compared with 90.3% for the first
         quarter of 2002. Exelon Generation's nuclear group completed two
         planned refueling outages during the first quarter of 2003 compared
         with four in the first quarter of 2002. Operating expenses associated
         with the planned refueling outages were approximately $32 million lower
         in the first quarter of 2003 compared with the prior year.

o        ComEd  Refinancing  Year-to-date,  ComEd has completed  $1.3 billion of
         securities  offerings as part of its ongoing  refinancing  program.  On
         January 22,  2003,  ComEd  closed on the sale of $350  million of 3.70%
         First Mortgage Bonds, which are due in 2008, and $350 million of 5.875%
         First Mortgage Bonds,  which are due in 2033. The net proceeds from the
         sale of the bonds  were  used to pay off  matured  or called  debt with


                                                                               2


         interest rates averaging about 6.5%. On March 17, 2003, ComEd closed on
         the sale of $200 million of 30-year  Trust  Preferred  Securities.  The
         securities carry a coupon of 6.35% and will mature in 2033. The purpose
         of the issue was to refund an existing ComEd trust preferred issue with
         an 8.48%  coupon.  On April 7, 2003,  ComEd  closed on the sale of $395
         million  of First  Mortgage  Bonds  maturing  in 2015  with a coupon of
         4.70%.  The  purpose  of the issue was to refund  debt with an  average
         interest rate of about 8.2%.

o        PECO Energy Refinancing On April 28, 2003, PECO Energy closed on the
         sale of $450 million of First Mortgage Bonds. The securities carry a
         3.5% coupon and will mature in 2008. Proceeds will be used to fund
         maturing debt with an average interest rate of about 6.5%.

o        March 3 Settlement  Agreement On March 28, 2003, the Illinois  Commerce
         Commission  (ICC)  entered  final orders for the three  docketed  cases
         included  in the  March 3  Agreement  entered  into by ComEd  and other
         interested parties.  The Agreement resolved several regulatory matters,
         and provided greater  certainty for the balance of ComEd's  competitive
         transition   period   through  2006  and  setting  the  stage  for  the
         post-transition  period.  The three  ICC  orders  established  delivery
         service rates for retail  customers not under the  traditional  bundled
         rates, rejected  disallowances proposed by the ICC's auditors and found
         ComEd's distribution plant additions to be prudent and used and useful,
         established  market value  energy  adders for  customers  who select an
         alternative  electricity  supplier  or the  purchase  power  option and
         approved an hourly  energy price rate that will be available to certain
         delivery  service  customers.  Other  provisions  of the  Agreement not
         subject to ICC action  include  the  funding  of certain  programs  for
         customer  and  governmental   groups  and  facilitating  the  potential
         extension of ComEd's  full-requirements  power purchase  agreement with
         its  generating  affiliate  through 2006. In the first  quarter,  ComEd
         recorded a $51 million (on a present  value basis before  income taxes)
         charge  related to the funding of certain  programs  for  customer  and
         governmental groups,  partially offset by the reversal of a $12 million
         (before income taxes) third quarter 2002 potential capital disallowance
         reserve and a $10 million  (before income taxes) credit also related to
         the ICC regulatory  order.  The net one-time  charge for these items is
         $17 million (after income taxes).

o        Exelon New England Exelon New England's Mystic 8 generating plant began
         commercial operation on April 13, 2003. Mystic 8 is an 807-MW gas-fired
         combined cycle plant with an estimated 7,000 heat rate located in
         Everett, MA (greater Boston area). The Mystic 9 plant is expected to
         begin commercial operation in May and ForeRiver in June 2003.


BUSINESS UNIT RESULTS

Exelon Corporation's consolidated net income for the first quarter of 2003 was
$361 million compared with net income of $8 million in the first quarter of
2002. Operating earnings were $397 million in the first quarter of 2003 compared
with operating earnings of $250 million in the first quarter of 2002.

Exelon Energy Delivery consists of the retail electricity transmission and
distribution operations of ComEd and PECO and the natural gas distribution
business of PECO. Energy Delivery's net income in the first quarter of 2003 was



                                                                               3


$330 million compared with net income of $215 million in the first quarter of
2002. First quarter 2003 net income includes the net $17 million after-tax
charge resulting from the March 3 ComEd Settlement Agreement and income of $5
million for the cumulative effect of adopting SFAS 143. The increase in net
income was primarily due to increased CTC recoveries at ComEd, increased sales
to residential and small commercial and industrial customers, including
weather-related electric and gas sales, lower interest costs and lower
depreciation rates at ComEd.

Heating degree-days for the first quarter of 2003 in the ComEd service territory
were up 17% relative to the same period in 2002 and 3% above normal. In the PECO
service territory, heating degree-days were up 33% compared with 2002 and 8%
above normal. Retail kWh deliveries rose 5.8% for ComEd, with a 7.4% increase in
deliveries to the residential customer class reflecting more heating degree-days
and a follow on to 2002's strong housing market. PECO's retail kWh deliveries
increased 11.5% overall, with residential deliveries up 18.7%. PECO's gas
deliveries increased 26.4% for the quarter and gas revenue increased 38.2% to
$288 million. Energy Delivery's first quarter 2003 revenues were $2,642 million,
up 13% from $2,335 million in 2002. Energy Delivery's first quarter 2003 fuel
and purchased power expense was $1,175 million, up 15% from $1,024 million in
2002. The impact of the colder weather increased Energy Delivery's first quarter
2003 earnings per share by approximately $0.14 relative to 2002, and $0.04
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. First quarter 2003 reported net income before
cumulative effect of a change in accounting principle (SFAS 143) was a loss of
$52 million and includes the $130 million after-tax impairment of the investment
in Sithe Energies. Net income after the cumulative effect of the change in
accounting principle was $56 million. First quarter 2002 net income and income
before cumulative effect of a change in accounting principle were $79 million
and $66 million, respectively. Income before cumulative effect in 2003 excluding
the $130 million Sithe impact exceeded 2002 by $12 million despite the $31
million (before tax) unrealized mark-to-market loss from non-trading activities
driven by higher power market prices relative to gas and oil market prices.
While the underlying instruments do not qualify for hedge accounting treatment,
they are part of the overall hedge strategy and, as such, we expect the loss to
be essentially offset by resulting physical asset transactions in 2003 and later
years. A $6 million (before tax) mark-to-market gain was recorded in the first
quarter of 2002.

Generation's first quarter 2003 revenue was $1,863 million, compared with first
quarter 2002 revenue of $1,461 million. The revenue increase reflects higher
energy market sales volumes, higher power prices and the 2002 acquisitions of
the New England plants and two Texas plants. Energy sales volumes, exclusive of
trading volumes, totaled 54,409 GWhs in the first quarter of 2003 compared with
48,324 GWhs in first quarter 2002.

Operating and maintenance expenses were up for the quarter as $19 million of
additional expenses resulting from the acquisitions of the New England and Texas
plants, higher pension and post-retirement benefit expense and the effects of
certain new accounting treatments under FAS 143, were partially offset by lower
expenses from fewer planned nuclear outages.

Power Team's revenue net fuel increased by $62 million in first quarter 2003
over first quarter 2002 excluding the mark-to-market impact in both years. The
improvement includes $32 million of margin contribution from the New England and
Texas plants acquired after the first quarter of 2002. The increase was driven


                                                                               4


by higher wholesale power prices in all regions in which Power Team operates, a
higher average power price to ComEd and higher nuclear generation, offset
partially by higher supply costs, including fuel and purchased power. The
average realized price excluding trading activity in the first quarter of 2003
was $34 per MWh compared with $30 per MWh in 2002. Higher market prices in both
MAIN and PJM, driven by higher market gas and oil prices and cold weather, were
partially offset by our hedged position during the quarter. The same factors,
cold weather and higher gas prices, also resulted in higher supply costs,
including purchased power and fuel costs.

Exelon Enterprises consists of Exelon's competitive retail energy sales, energy
and infrastructure services, venture capital investments and related businesses.
Enterprises' first quarter 2003 net loss and loss before cumulative effect of a
change in accounting principle were $18 million and $17 million, respectively.
The first quarter 2002 net loss and loss before cumulative effect of a change in
accounting principle were $271 million and $28 million, respectively. The
decrease in the first quarter 2003 loss before cumulative effect of a change in
accounting principle of $11 million is primarily the result of a reduction in
operating expenses, reduced costs from the discontinuance of retail sales in the
PJM region and a reduction in equity losses of unconsolidated affiliates.
Despite the continued weak economy, improvements were achieved in most
businesses. However, unplanned losses resulting from Exelon Energy exiting a key
supply agreement in the Northeast ($10.8 million) coupled with a write-down of a
venture capital investment ($3.0 million) contributed to the loss for the
quarter.

<FN>

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

(2)      Primarily related to cooler winter weather in 2003 versus 2002. Heating
         degree-days in the ComEd and PECO service  territories were 17% and 33%
         higher, respectively.

(3)      Reflects  increased  CTC  collections  by ComEd due to an  increase  in
         customer  shopping  and  changes  in  the  wholesale  market  price  of
         electricity,  net of  increased  mitigation  factors.  The  decrease in
         wholesale  prices also  resulted in a decrease in revenue  from ComEd's
         PPO customers.

(4)      O&M expense,  excluding outage costs, severance costs,  InfraSource and
         Energy  Services  O&Ms,  and the  March 3 ComEd  Settlement  Agreement,
         increased due to the implementation of SFAS 143, the acquisition of two
         generating  stations in Texas in April  2002,  and the  acquisition  of
         Sithe New England assets in November 2002.

(5)      Relates to four planned nuclear  refueling  outages in 2002 as compared
         to two refueling outages in 2003.

(6)      Depreciation and amortization  expense was lower primarily due to lower
         depreciation  rates and lower recoverable  transition cost amortization
         at ComEd and lower  decommissioning  expense at  Generation  due to the
         adoption  of SFAS  143,  partially  offset  by  increased  depreciation
         related to higher depreciable plant balances,  reflecting  Generation's
         plant acquisitions in 2002, and higher CTC amortization at PECO.

(7)      Reflects  less  outstanding  debt and  refinancing  of existing debt at
         lower interest rates,  partially offset by debt related to acquisitions
         after the first quarter of 2002.

(8)      Primarily   reflects  higher   investment  income  related  to  nuclear
         decommissioning trust funds.

(9)      Taxes Other Than Income was higher due to a favorable  2002  adjustment
         to real estate taxes on leased property held by ComEd.

(10)     Reflects  lower costs at  InfraSource  and Energy  Services,  partially
         offset by lower revenues.

(11)     Impairment of the investment held by Generation in Sithe Energies, Inc.

(12)     Agreement reached by ComEd and various Illinois  suppliers,  customers,
         and governmental  parties  regarding  several matters affecting ComEd's
         rates for electric service.

       the cost of energy and the delivery 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.


(c)    On May 1, 2002, all ComEd residential customers were eligible to choose their supplier of electricity;
       however, as of March 31, 2003, no alternative electric supplier has sought approval from the Illinois Commerce
       Commission and no electric utilities have chosen to enter the ComEd residential market for the supply of
       electricity.
