Item 5.  Other Events

     On July 24, 2001, Exelon Corporation issued the following press release.

     Exelon Reports Strong Second Quarter Earnings of $0.97 Per Diluted Share

Chicago  (July 24,  2001)  Exelon  Corporation  today  announced  operating  and
reported  earnings  of $315  million or $0.97 per  diluted  share for the second
quarter of 2001,  representing  a 17% increase over pro forma diluted  operating
earnings for the comparable  period in 2000.  Exelon operating  earnings for the
second  quarter of 2000 were $125  million  or $0.71 per  diluted  share,  which
represent  the  results of PECO  Energy and do not  reflect  the  effects of the
October 20, 2000 merger with Unicom  Corporation.  On a pro forma basis assuming
the merger of PECO  Energy and Unicom  Corporation  occurred on January 1, 2000,
second quarter 2000 earnings were $0.83 per diluted share.

Highlights for the quarter include:

o    Energy  sales of 48,522  GWh's which were 31% higher than pro forma  second
     quarter 2000. Wholesale market sales accounted for 42% of total sales.

o    Strong performance by Power Team, Exelon  Generation's  wholesale marketing
     division,  in April and May which was  partially  offset by the  effects of
     cool  weather  across most of the United  States and a decline in wholesale
     power prices in June.

o    The  addition of 800  megawatts  of  long-term  contracts to the Power Team
     supply portfolio.

o    Continuing superior performance by Exelon Generation's nuclear operations:
     o    a 93.6% nuclear capacity factor
     o    two record-breaking  refueling outages
     o    the  addition  of 129  megawatts  of  capacity  through  power  uprate
          projects at Byron and Braidwood

o    Exelon  Generation's  fossil operations  continue their strong  performance
     with:
     o    97% on time delivery
     o    94% dispatch availability

o    ComEd's on time completion of over 450 projects which formed the foundation
     of its rigorous 2001 summer  preparedness  and  infrastructure  improvement
     program.

Corbin A. McNeill, Co-CEO and Chairman, said, "The quarter confirmed, yet again,
Exelon's ability to meet its  commitments.  Despite cool weather and the fall in
wholesale  prices  in  June,  we've  produced  earnings  that  surpassed  market
expectations.  And we did it as  we've  done it in the  past:  through  superior
execution."



John W. Rowe,  Co-CEO and  President,  said, "I am delighted that our generation
group,  Power Team, PECO and ComEd delivery  operations all contributed to these
excellent  results.  While we expect larger  challenges  in the wholesale  power
markets  and in our  Enterprise  group  during the  second  half,  the  combined
strength of our generation, power marketing and energy delivery groups put us in
a strong position to meet our commitments for the year."

Ruth Ann Gillis,  Senior Vice President and Chief Financial  Officer,  confirmed
the  company's  previous  earnings  guidance.  She noted,  "We have had two good
quarters and we continue to believe our integrated strategy positions us to meet
our commitment of $4.50 earnings per share for 2001."

CORPORATE ISSUES
Second  quarter  earnings  reflect  goodwill  amortization  of $0.11 per  share.
Consistent with FASB's new accounting  standard for goodwill,  Exelon expects to
discontinue  annual  amortization  of  approximately  $140  million of goodwill,
effective January 1, 2002.

Merger-related  synergies  continue to be realized and Exelon expects to achieve
its target of $148 million this year.

BUSINESS UNIT RESULTS
Performance  for Exelon's  business  segments--Energy  Delivery,  Generation and
Enterprises--is  reported on the basis of earnings  before  interest  and income
taxes  (EBIT).  Exelon's  EBIT  increased  20% to $821  million  in the  quarter
compared to pro forma EBIT of $685 million in the second quarter of 2000.

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  operating  revenues were $2,436 million for the
current  quarter  compared  to pro forma  revenues  of $2,271  million  in 2000.
Operating  revenues reflect retail  kilowatt-hour  sales of 28,749 GWh's,  which
were  essentially  flat compared to the prior-year  sales of 28,764 GWh's due to
moderate  weather  conditions  and  the  impact  of  a  slower  economy.  Energy
Delivery's EBIT of $706 million in the second quarter of 2001 increased 10% over
the prior-year period pro forma EBIT of $643 million. ComEd's EBIT increased $73
million  primarily  as a result  of lower  operating  and  maintenance  expenses
compared to the prior year period.  PECO  Energy's  EBIT declined by $10 million
compared  to  the  prior-year  period  pro  forma  EBIT  due to an  increase  in
Competitive  Transition  Charge  amortization,  partially  offset  by  increased
delivery revenues, net of fuel costs.

ComEd's  distribution system  reliability,  delivery  performance,  and customer
satisfaction  statistics,  continued to improve, and PECO Energy was praised for
improved  customer  service in a report  recently  released by the  Pennsylvania
Public Utility Commission.



Generation  consists  of  Exelon's  electric  generation  facilities  and  power
marketing  operations.  Revenues increased 14% to $1,618 million compared to pro
forma revenues in the second quarter of 2000. This increase  reflects  continued
strong  nuclear  performance,  the expansion of power  marketing  activities and
additions  to the  supply  portfolio,  partially  offset by the  impact of lower
wholesale prices in both the PJM and ComEd markets.  Generation's second quarter
EBIT of $126  million  increased  66% over  pro  forma  EBIT for the  comparable
prior-year period of $76 million.

Exelon Generation is well on track to achieving its longer-term operating goals:

o    1,950 of the 3,000 megawatts targeted for this year have been acquired. The
     Power  Team  energy  supply  portfolio,   currently  totaling  over  41,000
     megawatts, is projected to grow to 49,000 megawatts by 2003.

o    243 of the  approximately  885  megawatts to be added  through power uprate
     projects by 2003 have been achieved.

o    The  year-to-date  June 30 nuclear capacity factor is 96.2% compared to the
     year-to-date  goal of 93%. The target capacity factor for the year is 91.6%
     reflecting five refueling outages scheduled for the fall.

Enterprises   consists  of   competitive   retail  energy   sales,   energy  and
infrastructure  services,  communications and related  investments.  Enterprises
revenues were $546 million in the second quarter, an increase of 36% compared to
second  quarter 2000 pro forma  revenues of $401 million.  EBIT was a loss of $5
million in the  quarter  compared to a pro forma EBIT loss of $42 million in the
second  quarter  of  2000.  Enterprises  EBIT  reflects  lower  margins  in  the
infrastructure  services  business,  which has been impacted by the  significant
downturn in the  telecommunications  industry.  The sluggish  performance of the
infrastructure services business was partially offset by a gain from the sale of
certain communications investments.
