Item 5.  Other Events

      On January 30, 2001, Exelon Corporation issued the following press
release. The Company has made non-material corrections to the wholesale and
non-regulated retail sales and telecommunication investments discussions in the
earnings per share reconciliation section of the press release.


           Exelon Announces 2000 Operating Earnings of $3.74 Per Share

      Chicago (January 30, 2001) - Exelon Corporation (NYSE: EXC) today
announced consolidated operating earnings of $764 million, or $3.74 per share
(diluted), for the year ended December 31, 2000. On October 20, 2000 Exelon
Corporation became the parent holding company of PECO Energy Company and the
subsidiaries of the former Unicom Corporation as a result of the merger of the
companies. Since the merger was accounted for as a purchase with PECO as the
acquirer, Exelon's 2000 earnings represent PECO Energy's 2000 earnings and the
earnings of the former Unicom Corporation and its subsidiaries since the October
20 merger. Accordingly, Exelon's 2000 earnings are measured against those of
PECO Energy for the comparable prior year period. Exelon's 2000 operating
earnings of $3.74 per share represent an 18% increase over PECO's 1999 operating
earnings of $3.17 per share.

      Operating earnings for 2000 exclude merger-related charges of $177 million
(after-tax), primarily for employee separation and regulatory approval costs,
and $21 million (after-tax) for the writedown of a telecommunications
investment. For the year, 2000 operating earnings also exclude a $24 million
(after-tax) benefit related to the non-recurring effect of a change in the
method of accounting for nuclear outage costs by PECO Energy as a result of the
synchronization of accounting policies of the merged companies. The cumulative
effect of the change in accounting method has been retroactively reflected as of
January 1, 2000 and will result in a restatement of Exelon Corporation's results
for the first three quarters of 2000. Also excluded from operating earnings are
extraordinary losses of $4 million (after-tax) for debt redemption premiums
incurred following PECO Energy's issuance of transition bonds in the second
quarter of 2000.

      Operating earnings for the fourth quarter of 2000 were $224 million, or
$0.78 per common share, exclusive of $156 million (after-tax) of merger-related
charges and $21 million (after-tax) for the writedown of a telecommunications
investment. Operating earnings include $24 million in amortization of goodwill
recorded since the October 20 merger date. Approximately $4.8 billion in
goodwill was recorded as a result of the PECO and Unicom merger, which is being
amortized over 40 years. Goodwill represents the excess of the purchase price
over the fair value of the Unicom assets acquired, and reflects a $2.9 billion
(after-tax) writedown of Unicom's nuclear generating stations to fair value, as
well as the accrual of employee separation costs.




      Corbin A. McNeill, Jr., Exelon Chairman and Co-CEO, stated that "our 2000
performance confirms Exelon's ability to deliver on its commitments and
highlights the tremendous potential inherent in this Company's physical and
intellectual assets. Exelon Nuclear achieved a 99% capacity factor in December
to finish the year at 94%, up from 89% in 1999." McNeill said he found the
nuclear performance "all the more remarkable in a year in which we reduced
nuclear production costs 9.5% and conducted eight of the nine shortest
refuelings in the country."

      "Exelon Nuclear's superior performance helped ensure a reliable supply of
electricity in a period of record demand for power, as well as increasing
off-system sales volumes," said John W. Rowe, Exelon Co-CEO and President. In
comparing the power supply situations in Pennsylvania and Illinois to
California, Rowe noted, "Illinois and Pennsylvania legislators provided for a
phased-in approach to retail competition that has allowed for the development of
wholesale supplies of power sufficient to meet demand."

      Also of note, Exelon successfully completed the legal restructuring of its
competitive generation and enterprises businesses on January 12, 2001. This new
company structure separates Exelon's regulated energy delivery business from its
competitive generation and other businesses and streamlines the process for
managing, operating and tracking the financial performance of Exelon's multiple
lines of business.

Notes on Fourth Quarter Earnings Variances:
- -------------------------------------------

Regulated Retail Sales:
- -----------------------

Variance reflects colder weather in the PECO service region relative to the same
period in 1999 and higher customer retention as well as the favorable effects of
the January 1, 2000 rate increase on retail sales. The total volume of kWh
delivered by PECO Energy Distribution during the fourth quarter of 2000 and 1999
were 8.67 billion kWhs and 8.18 billion kWhs, respectively. The increase in
deliveries was the result of colder weather and higher customer retention.
Heating degree days recorded in the fourth quarter 2000 were 30% greater than
those recorded in the same period in 1999, and equal to normal heating degree
days expected for the period. The percentage of kWhs delivered by competitive
suppliers in the fourth quarter of 2000 and 1999 were 33% and 40%, respectively.

Wholesale & Non-regulated Retail Sales:
- ---------------------------------------

The negative variance in the fourth quarter is primarily attributable to higher
supply costs for wholesale and unregulated retail operations partially offset by
higher market sales for Power Team.

For the twelve months ended December 31, 2000, wholesale sales volume was down
as compared to the same period last year, however gross margins were up due to a
lower cost of supply in the second and third quarters of 2000. Also contributing
to this positive variance for the twelve month period is better performance
overall for Exelon Energy in managing supply and demand obligations.

Exelon Infrastructure Services:
- -------------------------------

The negative variance reflects an increase in O&M expenses greater than the
increase in revenues over the prior-year period and additional goodwill related
to acquisitions in December 2000.

Operation and Maintenance:
- --------------------------

The positive variance is primarily attributable to the combined effect of the
elimination of Y2K activities partially offset by higher non-utility operation
expenses.

Depreciation & Amortization:
- ----------------------------

The negative variance is primarily the result of the January 1, 2000 initiation
of CTC/ITC amortization to recognize stranded cost recovery.

Taxes Other Than Income:
- ------------------------

The positive variance reflects the combined effect of lower gross receipts,
capital stock, and real estate taxes.

Interest Expense:
- -----------------

The negative variance includes additional interest expense over the prior-year
period related to the $1 billion of transition bonds issued in the second
quarter of 2000. Approximately, $500 million of the proceeds were used to
reacquire PECO common stock and approximately $500 million was used to retire
higher cost debt.

Telecommunication Investments:
- ------------------------------

The negative variance reflects the change in combined equity earnings for all of
the Company's telecommunication investments. This variance was partially offset
by reduced losses in each of the AT&T and Hyperion joint ventures. At year-end
2000 and 1999, AT&T Wireless served 215,000 and 146,000 customers, respectively,
in the Philadelphia region.

AmerGen:
- --------

AmerGen's results for the fourth quarter reflect its equity in the losses
incurred by Oyster Creek Nuclear Power Station, partially offset by the earnings
contributions from TMI-1 and Clinton nuclear stations. As anticipated, Oyster
Creek's fall refueling and maintenance outage (10/13/00 - 11/14/00) resulted in
an approximate $24 million charge to net income in the fourth quarter. Fourth
quarter results for the combined AmerGen fleet also reflect charges to adjust
pension and other employee-related expenses at each plant.

Shares Outstanding:
- -------------------

Reflects the earnings per share impact of the change in the outstanding share
balance caused by the second quarter share repurchase executed by PECO.

Unicom Post-Merger Contribution to Consolidated Earnings (10/20/00- 12/31/00)
- -----------------------------------------------------------------------------

The positive variance reflects the net earnings contribution of the former
Unicom operations from October 20, 2000 through December 31, 2000. Unicom's
contribution to operating results for this period was $106 million. This
positive contribution was partially offset by an increase in weighted average
shares outstanding as a result of the issuance of 148 million Exelon common
shares to former Unicom shareholders on October 20, 2000 in connection with the
merger. Immediately prior to the merger close, PECO's share balance was 170
million. At December 31, 2000, Exelon had 319 million shares outstanding.

The Unicom results also include $24 million of amortization expense related to
merger goodwill.

Special Items, Extraordinary Item & Cumulative Effect of a Change in Accounting
- -------------------------------------------------------------------------------
Principle:
- ----------

Merger Related Expenses:

This special item in fourth quarter earnings reflects $159 million (after-tax)
of merger-related expenses principally consisting of severance, regulatory
settlement charges, termination of certain compensation plans and incremental
merger expenses.

Writedown of Telecommunication Investment:

This special item in fourth quarter earnings reflects a $22 million (after-tax)
writedown of Exelon Capital's Investment in Vitts Networks, Inc.

Extraordinary Item:

The extraordinary charge in the year to date period of $4 million (after-tax)
consists of prepayment premiums and the write-off of unamortized deferred
financing costs associated with the early retirement of debt during 2000.

Cumulative Effect of a Change in Accounting Principle:

The cumulative effect item in the year to date period reflects a $24 million
(after-tax) benefit for a non-recurring change in accounting method for nuclear
outage costs by PECO Energy as of January 1, 2000 related to the synchronization
of accounting policies in connection with the Unicom merger.
