        Exelon Reports Third Quarter Earnings of $1.25 Per Diluted Share

Chicago (October 23, 2001) Exelon Corporation today announced reported earnings
of $403 million or $1.25 per diluted share for the third quarter of 2001. The
reported $1.25 per diluted share exceeds the high end of our recent guidance due
to higher estimates for unbilled revenue than were used in developing the
guidance. Reported results include three non-recurring items that lowered
reported earnings by $0.16 per share. Exelon's reported earnings for the third
quarter of 2000 were $232 million or $1.35 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, third quarter
2000 earnings were $1.27 per diluted share.

On September 27, Exelon lowered its 2001 earnings guidance to a range of $4.30
to $4.45 per diluted share down from the original $4.50. This guidance, which
remains our best judgment, represents reported earnings without adjustment for
any one-time items incurred during the year. The forecasted earnings range
represents an 11% to 15% increase over pro forma earnings for the year 2000 of
$3.86.

The company is in the process of finalizing its budget and earnings models for
2002. Our current outlook for 2002 is a range of $4.45 to $4.85 per diluted
share, which reflects the national economic slowdown and wholesale price
volatility.

Third Quarter Highlights:

Factors influencing third quarter results are as follows:



Page 2



o    Energy sales by Exelon Generation totaled 54,342 GWhs, a 7% increase over
     pro forma third quarter 2000 energy sales of 50,733 GWhs. Approximately 64%
     of third quarter 2001 energy sales were to affiliates.

o    Lower energy-market prices adversely affected Exelon Generation's Power
     Team performance in the third quarter compared with expectations. Wholesale
     margins realized were lower than originally incorporated in the third
     quarter earnings outlook.

o    Exelon Generation's nuclear fleet continues to operate above target with:
     o    95.0% nuclear capacity factor for the third quarter
     o    95.1% year-to-date through September 30

o    Exelon Generation's fossil operations continue their strong performance
     with:
     o    98% on time delivery
     o    94.3% dispatch availability

o    ComEd continues to improve the reliability and efficiency of its delivery
     operations in a summer in which two new all-time peaks were set. On August
     9, ComEd set a new all-time peak load of 21,574 MW.

Non-recurring Items: Third quarter 2001 reported earnings of $1.25 per diluted
share include the effects of the following non-recurring charges:

o    Employee severance costs of $31 million ($0.06 per share) related to
     approximately 500 additional positions identified to be eliminated as a
     result of the 2000 merger of PECO Energy and Unicom.

o    A $36 million ($0.07 per share) writedown of its investment in Corvis, a
     telecommunications equipment manufacturer.

o    A $14 million ($0.03 per share) increase in reserves in conjunction with a
     tentative settlement of litigation involving PECO Energy's decision not to
     proceed with the proposed purchase of a minority interest in the River Bend
     generating facility. The settlement should be finalized shortly.

Exelon's Co-CEO and Chairman, Corbin A. McNeill Jr., said that, "Demand and
prices did not materialize to the extent we planned this summer, and we learned
a good deal about how to prepare for next year. The market decline was
especially frustrating given the very strong operating performance in
Generation. Since the end of June, Exelon Nuclear completed another power uprate
project, two refuelings, and remained on track towards its all-in cost goal of 2
cents/kWh. In early August, during the one summer heat wave, every one of our
fossil plants ran flat out and was available for dispatch over 94% of the time."

John W. Rowe, Co-CEO and President, said, "In the first real test of the
infrastructure improvements we've been making for the past two years, the ComEd
distribution system performed superbly. The turn-around in performance is clear,
real and we intend to make it permanent. In the long run, it's our ability to
generate low-cost power and deliver it reliably that will be the basis for
Exelon's ability to deliver shareholder value."

CORPORATE ISSUES
Third quarter earnings reflect goodwill amortization of $37 million or $0.12 per
share. Goodwill amortization is expected to total $151 million, or $0.47 per
share, in 2001. Consistent with the recently issued accounting standard for
goodwill, Exelon expects to discontinue amortization of goodwill, effective
January 1, 2002. Goodwill will be reviewed for impairment and possible
adjustment.

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

BUSINESS UNIT RESULTS
Performance of 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 for the third quarter of 2001 was $931 million
compared to pro forma EBIT of $920 million in the third quarter of 2000.

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 EBIT of $704 million in
the third quarter of 2001 compares to pro forma EBIT of $685 million in the
prior-year period. The segment benefited from increased deliveries to
residential customers during the quarter as a result of warmer summer weather
compared to last year, but experienced declines in deliveries to large
commercial and industrial customers as a result of a slowing economy.

Exelon Generation consists of Exelon's electric generation operations and power
marketing and trading functions. Generation's third quarter 2001 EBIT was $278
million, compared to pro forma EBIT of $300 million last year. Generation
experienced increased sales volumes and continued strong nuclear and fossil
station performance, but overall margins were adversely affected by lower
wholesale electricity market prices. Generation's third quarter 2001 EBIT
includes a $14 million charge for litigation settlement costs.

Exelon Enterprises consists of competitive retail energy sales, energy and
infrastructure services, communications and related investments. Enterprises'
EBIT for the third quarter of 2001 was a loss of $44 million compared to third
quarter 2000 pro forma loss of $67 million. The third quarter EBIT improvement
reflects improved margins and a reduction of operating expenses at Exelon
Energy. The third quarter 2001 results include the $36 million writedown of an
investment in Corvis.
