                   Exelon Corporation and Subsidiary Companies
                   Financial Statements and Supplementary Data






                        Report of Independent Accountants

To the Shareholders and
Board of Directors of
Exelon Corporation:


In our  opinion,  the  accompanying  consolidated  balance  sheets  and  related
consolidated  statements  of  income,  cash flows and  changes in  shareholders'
equity and comprehensive  income present fairly, in all material  respects,  the
financial  position of Exelon  Corporation and Subsidiary  Companies (Exelon) at
December 31, 2000 and December 31, 1999, and the results of their operations and
their cash flows for each of the three years in the period  ended  December  31,
2000 in conformity with accounting  principles  generally accepted in the United
States of America. These financial statements are the responsibility of Exelon's
management;  our  responsibility  is to express  an  opinion on these  financial
statements  based on our audits.  We conducted our audits of these statements in
accordance with auditing  standards  generally  accepted in the United States of
America,  which require that we plan and perform the audit to obtain  reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting  principles  used and significant  estimates made by management,  and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

As discussed in Note 1 to the consolidated financial statements, Exelon acquired
Unicom Corporation on October 20, 2000 in a business  combination  accounted for
under the purchase method of accounting.  The results of Unicom  Corporation are
included in the consolidated financial statements since the acquisition date.

As discussed in Note 4 to the consolidated financial statements,  Exelon changed
its method of accounting for nuclear outage costs in 2000.

                   Exelon Corporation and Subsidiary Companies
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
       (Dollars in millions, except per share data unless otherwise noted)

1. Significant Accounting Policies

Description of Business
         On October 20,  2000,  Exelon  Corporation  (Exelon)  became the parent
corporation  for each of PECO  Energy  Company  (PECO) and  Commonwealth  Edison
Company  (ComEd).  See Note 2 - Merger.  Exelon is a  utility  services  holding
company  engaged,  through  its  subsidiaries,  in  the  production,   purchase,
transmission,   distribution  and  sale  of  electricity  to  5  million  retail
customers,  and the  distribution  and sale of  natural  gas to  425,000  retail
customers.  Exelon's retail electric service territories are located principally
in southeastern Pennsylvania,  including the City of Philadelphia,  and northern
Illinois,  including metropolitan Chicago.  Exelon also engages in the wholesale
marketing   of   electricity,   the   provision   of   utility   infrastructure,
communications  and other  utility  related  services in various  regions of the
United States.

Basis of Presentation
         The consolidated financial statements of Exelon include the accounts of
its   majority-owned   subsidiaries   after  the   elimination  of  intercompany
transactions.  Exelon  accounts for its 20% to 50% owned  investments  and joint
ventures, in which it exerts significant  influence,  under the equity method of
accounting.  Exelon consolidates its proportionate interest in its jointly owned
electric utility plants. Exelon accounts for its less than 20% owned investments
under  the  cost  method  of  accounting.   Accounting  policies  for  regulated
operations are in accordance with those prescribed by the regulatory authorities
having  jurisdiction,  principally the  Pennsylvania  Public Utility  Commission
(PUC), the Illinois  Commerce  Commission  (ICC), the Federal Energy  Regulatory
Commission  (FERC) and the  Securities and Exchange  Commission  (SEC) under the
Public Utility Holding Company Act of 1935 (PUHCA).

         Exelon, formed as a wholly owned subsidiary of PECO in 1999, became the
parent company of PECO when each share of  outstanding  common stock of PECO was
exchanged for one share of Exelon  common stock in  connection  with the merger.
See Note 2 - Merger. In addition,  for accounting purposes,  PECO was deemed the
acquiror in the merger.  Accordingly,  the financial  statements for the periods
presented represent the historical  financial statements of PECO pursuant to the
reorganization  and the historical  information of the former Unicom entity from
October 20, 2000 reflecting the acquisition.

Accounting for the Effects of Regulation
         Exelon accounts for all of its regulated electric and gas operations in
accordance  with  Statement of  Financial  Accounting  Standards  (SFAS) No. 71,
"Accounting for the Effects of Certain Types of Regulation," requiring Exelon to
record the  financial  statement  effects of the rate  regulation  to which such
operations  are  currently  subject.  Use of SFAS No.  71 is  applicable  to the
utility operations of Exelon that meet the following  criteria:  (1) third-party
regulation of rates; (2) cost-based rates; and (3) a reasonable  assumption that
all costs will be recoverable from customers through rates. Exelon believes that
it is probable that regulatory  assets  associated with these operations will be
recovered.  If a  separable  portion of Exelon's  business  no longer  meets the
provisions  of SFAS No.  71,  Exelon is  required  to  eliminate  the  financial
statement effects of regulation for that portion.

Use of Estimates
         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.


                                                                          Page 7


Revenues
         Operating  revenues  are  generally  recorded as service is rendered or
energy is delivered to customers.  At the end of each month,  Exelon  accrues an
estimate for the unbilled amount of energy delivered or services provided to its
electric and gas customers.  Exelon  recognizes  contract revenue and profits on
long-term   fixed-price   contracts   from  its  services   businesses   by  the
percentage-of-completion  method  of  accounting  based on costs  incurred  as a
percentage of estimated total costs of individual contracts.

Purchased Gas Adjustment Clause
         PECO's  natural  gas  rates are  subject  to a fuel  adjustment  clause
designed  to  recover  or refund  the  difference  between  the  actual  cost of
purchased  gas and the amount  included in base rates.  Differences  between the
amounts  billed to customers and the actual costs  recoverable  are deferred and
recovered  or  refunded  in future  periods  by means of  prospective  quarterly
adjustments to rates.

Nuclear Fuel
         The cost of nuclear  fuel is  capitalized  and charged to fuel  expense
using the unit of production  method.  Estimated  costs of nuclear fuel disposal
are charged to fuel expense as the related fuel is consumed.

Depreciation, Amortization and Decommissioning
         Depreciation is provided over the estimated  service lives of property,
plant and equipment on a straight line basis. Annual depreciation provisions for
financial reporting purposes,  expressed as a percentage of average service life
for each asset category are presented below:

    Asset Category                                    2000     1999     1998
    --------------                                    ----     ----     ----

    Electric -- Transmission and Distribution         4.16%    1.83%    1.96%
    Electric -- Generation                            5.02%    5.12%    5.26%
    Gas                                               2.39%    2.36%    2.40%
    Common                                            2.10%    2.13%    4.54%
    Other Property and Equipment                      8.11%    8.61%    2.80%

         Amortization of regulatory  assets is provided over the recovery period
as specified in the related regulatory  agreement.  Goodwill associated with the
merger is being  amortized on a straight line basis over 40 years.  See Note 2 -
Merger.  Goodwill  associated  with other  acquisitions  is being amortized over
periods  from 10 to 20  years.  Accumulated  amortization  of  goodwill  was $35
million and $1 million at December 31, 2000 and 1999, respectively.

         Exelon's  estimate  of  the  costs  for   decommissioning  its  nuclear
generating  stations is  currently  included  in  regulated  rates.  The amounts
recovered  from  customers  are  deposited  in trust  accounts  and invested for
funding of future costs for current and retired plants.  Exelon accounts for the
current period's cost of  decommissioning  by recording a charge to depreciation
expense  and a  corresponding  liability  in  accumulated  depreciation  for its
operating  nuclear  units and a reduction to  regulatory  assets for its retired
units.  Exelon believes that the amounts being recovered from customers  through
electric  rates along with the earnings on the trust funds will be sufficient to
fully fund its decommissioning obligations.

Capitalized Interest
         Exelon uses SFAS No. 34,  "Capitalizing  Interest  Costs," to calculate
the costs during  construction  of debt funds used to finance its  non-regulated
construction  projects.  Exelon recorded  capitalized interest of $2 million, $6
million and $7 million in 2000, 1999 and 1998, respectively.

         Allowance  for Funds  Used  During  Construction  (AFUDC)  is the cost,
during the  period of  construction,  of debt and  equity  funds used to finance
construction projects for regulated operations. AFUDC is recorded as a charge to
Construction  Work in  Progress  and as a  non-cash  credit  to  AFUDC  which is
included in Other Income and Deductions.  The rates used for capitalizing  AFUDC
are computed under a method prescribed by regulatory authorities.



                                                                          Page 8


Income Taxes
         Deferred Federal and state income taxes are provided on all significant
temporary   differences   between  book  bases  and  tax  bases  of  assets  and
liabilities,  transactions  that reflect taxable income in a year different from
book income and tax carryforwards.  Investment tax credits  previously  utilized
for income tax purposes have been deferred on the  Consolidated  Balance  Sheets
and are recognized in book income over the life of the related property.  Exelon
and its subsidiaries file a consolidated Federal income tax return. Income taxes
are allocated to each of Exelon's  subsidiaries  within the  consolidated  group
based on the separate return method.

Gains and Losses on Reacquired Debt
         Gains  and  losses  on  reacquired  debt  are  recognized  in  Exelon's
Consolidated  Statements  of Income as incurred.  Gains and losses on reacquired
debt related to regulated  operations  incurred  prior to January 1, 1998,  have
been  deferred  and are being  amortized  to  interest  expense  over the period
approved for ratemaking purposes.

Comprehensive Income
         Comprehensive  income  includes  all changes in equity  during a period
except those resulting from  investments by and  distributions  to shareholders.
Comprehensive  income is reflected in the Consolidated  Statements of Changes in
Shareholders' Equity and Comprehensive Income.

Cash and Cash Equivalents
         Exelon  considers  all temporary  cash  investments  purchased  with an
original maturity of three months or less to be cash equivalents.

Marketable Securities
         Marketable securities are classified as  available-for-sale  securities
and are reported at fair value,  with the  unrealized  gains and losses,  net of
tax,  reported in other  comprehensive  income.  Unrealized  gains and losses on
marketable  securities  held in the  nuclear  decommissioning  trust  funds  are
reported in accumulated  depreciation  for operating units and as a reduction of
regulatory  assets for retired units. At December 31, 2000 and 1999,  Exelon had
no held-to-maturity or trading securities.

Property, Plant and Equipment
         Property, plant and equipment is recorded at cost. Exelon evaluates the
carrying value of property, plant and equipment and other long-term assets based
upon  current  and  anticipated  undiscounted  cash  flows,  and  recognizes  an
impairment  when it is probable that such estimated cash flows will be less than
the carrying value of the asset.  Measurement  of the amount of  impairment,  if
any, is based upon the difference  between  carrying  value and fair value.  The
cost of maintenance,  repairs and minor  replacements of property are charged to
maintenance expense as incurred.

         Upon retirement, the cost of regulated property plus removal costs less
salvage  value,  are  charged  to  accumulated  depreciation  by  the  regulated
subsidiaries  in accordance  with the provisions of SFAS No. 71. For unregulated
property, the cost and accumulated depreciation of property, plant and equipment
retired or  otherwise  disposed of are removed  from the  related  accounts  and
included in the determination of the gain or loss on disposition.

Capitalized Software Costs
         Costs incurred  during the  application  development  stage of software
projects  for  software  which is  developed  or obtained  for  internal use are
capitalized.  At December 31, 2000 and 1999,  capitalized software costs totaled
$285 million and $105 million,  respectively, net of $53 million and $32 million
accumulated amortization,  respectively.  Such capitalized amounts are amortized
ratably over the expected  lives of the projects  when they become  operational,
not to exceed ten years.  Certain  capitalized  software is being amortized over
fifteen years pursuant to regulatory approval.

Retail and Wholesale Energy Commitments
         In the normal  course of business,  Exelon  utilizes  contracts for the
forward sale and purchase of energy to manage the  utilization  of its available
generating   capability  and  provision  of  wholesale   energy  to


                                                                          Page 9


its retail  affiliates.  Exelon also utilizes energy option contracts and energy
financial swap  arrangements  to limit the market price risk associated with the
forward energy commodity contracts. Through December 31, 2000, Exelon recognized
any  gains  or  losses  on  forward  commodity  contracts  when  the  underlying
transactions affect earnings. Revenues and expenses associated with market price
risk management contracts are amortized over the terms of such contracts.

         At December 31, 2000, Exelon's retail and wholesale activities included
short-term and long-term commitments,  which are carried at the lower of cost or
market,  to purchase and sell energy and  energy-related  products in the retail
and wholesale  markets with the intent and ability to deliver or take  delivery.
Revenue and expense  associated with energy  commitments is reported at the time
the underlying physical transaction affects earnings.

Hedge Accounting
         Hedge accounting is applied only if the derivative  reduces the risk of
the  underlying  hedged item and is  designated  at inception  as a hedge,  with
respect  to the  hedged  item.  If a  derivative  instrument  ceased to meet the
criteria for deferral, any gains or losses are recognized in income.

New Accounting Pronouncements
         In June 1998, the Financial  Accounting  Standards  Board (FASB) issued
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," to
establish  accounting and reporting standards for derivatives.  The new standard
requires  recognizing  all  derivatives  as either assets or  liabilities on the
balance sheet at their fair value and specifies  the  accounting  for changes in
fair value depending upon the intended use of the derivative.  In June 1999, the
FASB issued SFAS No. 137  "Accounting  for  Derivative  Instruments  and Hedging
Activities - Deferral of the  Effective  Date of FASB  Statement No. 133," which
delayed the effective date for SFAS No. 133 until fiscal years  beginning  after
June 15, 2000.  The effect of adopting SFAS No. 133 in the first quarter of 2001
will result in a cumulative  after-tax  increase in net income of  approximately
$17 million and other  comprehensive  income of  approximately  $21 million. The
adoption  will  also  impact  the  assets  and   liabilities   recorded  on  the
Consolidated  Balance  Sheets  of  Exelon  and may  result  in  future  earnings
volatility.  The determination of the impact of SFAS No. 133 is based on current
interpretations  of SFAS No. 133,  including  interpretations of the Derivatives
Implementation  Group of the  FASB,  related  to the  treatment  of  electricity
capacity  contracts.  If final guidance,  when issued,  changes the treatment of
electricity  capacity  contracts,  the effects of the implementation of SFAS No.
133 may differ from the amounts disclosed above.

         In  September  2000,  the FASB  issued SFAS No.  140,  "Accounting  for
Transfers and Servicing of Financial Assets and  Extinguishments of Liabilities,
a  Replacement  of FASB  Statement  No,  125."  This new  standard  revises  the
standards for accounting for  securitizations  and other  transfers of financial
assets and collateral and requires certain disclosures, but it carries over most
of the provisions of SFAS No. 125without reconsideration.  SFAS No. 140 provides
accounting  and  reporting  standards  for  transfers and servicing of financial
assets  and  extinguishments  of  liabilities.  SFAS No.  140 is  effective  for
transfers and servicing of financial assets and  extinguishments  of liabilities
occurring after March 31, 2001 and should be applied prospectively.  At December
31, 2000, Exelon did not anticipate entering into any transactions that would be
subject to the provisions of SFAS No. 140 when it becomes effective.

Reclassifications
         Dividends  on  preferred  stock of PECO for  1999  and 1998  have  been
reclassified to Distributions on Preferred Securities of Subsidiaries, resulting
in a deduction  before,  rather than after,  net income.  This  reclassification
reflects the current  organizational  structure in which PECO is a subsidiary of
Exelon.  Certain other prior year amounts have been reclassified for comparative
purposes.



                                                                         Page 10



2. Merger

         On October 20, 2000,  Exelon became the parent  corporation for each of
PECO and ComEd as a result of the completion of the transactions contemplated by
an Agreement  and Plan of Exchange and Merger,  as amended  (Merger  Agreement),
among PECO,  Unicom  Corporation  (Unicom)  and  Exelon.  Pursuant to the Merger
Agreement,  (a) each share of outstanding common stock of PECO was exchanged for
one share of common stock of Exelon (Share  Exchange) and (b) Unicom merged with
and  into  Exelon  (Merger  and  together  with  the  Share   Exchange,   Merger
Transaction).  In the Merger  Transaction,  each share of the outstanding common
stock of Unicom was  converted  into 0.875 shares of common stock of Exelon plus
$3.00  in  cash.  Also  pursuant  to  the  Merger  Agreement,  PECO  and  Unicom
repurchased  approximately  $1.5 billion of common stock prior to the closing of
the Merger Transaction,  with Unicom repurchasing  approximately $1.0 billion of
its common stock, and PECO repurchasing approximately $500 million of its common
stock. As a result of the Share Exchange,  Exelon became the owner of all of the
common stock of PECO. As a result of the Merger,  Unicom ceased to exist and its
subsidiaries, including ComEd, became subsidiaries of Exelon.

         The Merger was accounted for using the purchase  method of  accounting.
The total  purchase  price was $5,973  million.  In connection  with the Merger,
Exelon issued 148 million shares of common stock in the amount of $5,310 million
and paid $507  million in cash to Unicom  shareholders  pursuant to the terms of
the Merger Agreement.  The source of the cash consideration was borrowings under
an Exelon term loan. In addition, the merger consideration included $111 million
of fair value of stock options and awards for certain  Unicom  employees and $45
million of direct  acquisition  costs. The cost in excess of net assets acquired
was $4,874 million,  which will be amortized over forty years.  Exelon's results
of operations include Unicom's results of operations since October 20, 2000. The
purchase price allocation is preliminary and further  refinement may occur based
upon the final resolution of employee severance  obligations.  The fair value of
the assets acquired,  including the cost in excess of net assets  acquired,  and
liabilities assumed in the Merger are as follows:

             Current Assets (including cash of $974)                 $2,751

                                                                         Page 11


Merger-Related Costs
         In association  with the Merger  Transaction,  Exelon recorded  certain
reserves for restructuring costs. The reserves associated with PECO were charged
to expense,  while the reserves  associated with Unicom were recorded as part of
the application of purchase accounting and did not affect results of operations.

         Merger-related  costs  charged  to  expense  in 2000 were $276  million
consisting  of $152  million of direct  incremental  costs and $124  million for
employee costs.  Direct incremental costs represent expenses directly associated
with completing the Merger Transaction,  including professional fees, regulatory
approval and  settlement  costs,  and settlement of  compensation  arrangements.
Employee  costs  represent   estimated   severance   payments  and  pension  and
postretirement benefits provided under Exelon's Merger Separation Plan (MSP) for
eligible  employees  who are  expected  to be  involuntarily  terminated  before
October 2002 due to integration activities of the merged companies.

         Included in the purchase price allocation is a liability for exit costs
of $307 million for  additional  employee  costs and  additional  liabilities of
approximately  $39  million  for  estimated  costs of exiting  various  business
activities  of  former  Unicom  activities  that  were not  compatible  with the
strategic  business  direction of Exelon.  The employee  costs include  employee
severance,   actuarially  determined  pension  and  post-retirement  costs,  and
relocation  and other  benefits of $128  million,  $158 million and $21 million,
respectively.  The involuntary  terminations are a result of merger  integration
and  reengineering  of processes,  primarily in the areas of corporate  support,
generation, and energy delivery. The $307 million estimated liability is subject
to a final determination of the level of benefits to be provided to a portion of
the employees  whose  positions are expected to be eliminated as a result of the
merger but are not eligible for the MSP. Adjustments to the liability to reflect
final  determination  of benefit  levels will be recorded  as an  adjustment  to
goodwill.

         Approximately  2,900 positions have been identified to be eliminated as
a result of the Merger  Transaction.  Exelon  anticipates  that $282  million of
employee costs will be funded from its pension and postretirement  benefit plans
and $149 million will be funded from general  corporate  funds.  At December 31,
2000, the reserve balance for employee severance,  relocation and other benefits
was $144 million and is expected to be expended by October 2002.


3. Acquisitions

Sithe Energies, Inc. Acquisition
         On December 18, 2000,  Exelon acquired 49.9% of the outstanding  common
stock of Sithe  Energies,  Inc.  (Sithe)  for $704  million,  with an  option to
purchase the remaining  common stock  outstanding  exercisable  between December
2002 and December 2005, at a price to be determined  based on prevailing  market
conditions.

         Sithe is an  independent  power  generator in North  America  utilizing
primarily  fossil and hydro  generation.  The  purchase  involves  approximately
10,000 megawatts (MW) of generation  consisting of 3,800 MW of existing merchant
generation,  2,500 MW under construction,  and another 3,700 MW of generation in
various  stages  of  development,  as well as  Sithe's  domestic  marketing  and
development   businesses.   The  generation  assets  are  located  primarily  in
Massachusetts and New York, but also include plants in Pennsylvania, California,
Colorado and Idaho, as well as Canada and Mexico.

Exelon Infrastructure Services, Inc. Acquisitions
         In 2000,  Exelon  Infrastructure  Services,  Inc. (EIS), an unregulated
majority  owned  subsidiary  of  Exelon,  acquired  the stock or assets of seven
utility  service  contracting  companies  for an  aggregate  purchase  price  of
approximately  $245 million,  net of cash acquired of $9 million,  including EIS
common stock valued at $14 million.  The  acquisitions  were accounted for using
the  purchase  method of  accounting.  The  initial  estimate  of the  excess of
purchase price over the fair value of net assets acquired was approximately $216
million.



                                                                         Page 12


         The allocation of purchase  price to the fair value of assets  acquired
and liabilities assumed in these acquisitions is as follows:

Current Assets (net of cash acquired)       $  63
Property, Plant and Equipment                  17
Cost in excess of net assets acquired         216
Current Liabilities                           (51)
                                           ------
Total                                       $ 245
                                            =====

         Cost in excess of net assets acquired  associated with EIS acquisitions
is being amortized over 20 years.

         At December 31, 2000 and 1999,  Current Assets includes $70 million and
$48  million,  respectively,  of Costs and  Earnings  in Excess of  Billings  on
uncompleted  contracts  and  Current  Liabilities  includes  $23  million and $9
million,   respectively,  of  Billings  and  Earnings  in  Excess  of  Costs  on
uncompleted contracts.

AmerGen Energy Company, LLC
         In August 2000,  AmerGen Energy Company LLC (AmerGen),  a joint venture
with British  Energy,  Inc., a wholly owned  subsidiary  of British  Energy plc,
(British  Energy),  completed  the purchase of Oyster Creek  Nuclear  Generating
Facility (Oyster Creek) from GPU, Inc. (GPU) for $10 million. Under the terms of
the  purchase  agreement,  GPU  agreed to fund  outage  costs not to exceed  $89
million,  including  the cost of fuel,  for a refueling  outage that occurred in
2000.  AmerGen will repay these costs to GPU in nine equal  annual  installments
beginning in August 2001. In addition,  AmerGen assumed full  responsibility for
the ultimate  decommissioning  of Oyster Creek.  At the closing of the sale, GPU
provided funding for the  decommissioning  trust of $440 million. In conjunction
with this acquisition, AmerGen has received a fully funded decommissioning trust
fund which has been computed  assuming the  anticipated  costs to  appropriately
decommission  Oyster  Creek  discounted  to net  present  value  using the NRC's
mandated  rate of 2%.  AmerGen  believes  that the  amount of the trust fund and
investment  earnings  thereon  will be  sufficient  to meet its  decommissioning
obligation. GPU is purchasing the electricity generated by Oyster Creek pursuant
to a three-year power purchase agreement.


4. Accounting Change

         During the fourth  quarter of 2000, as a result of the  synchronization
of accounting  policies with Unicom in connection  with the Merger  Transaction,
PECO changed its method of  accounting  for nuclear  outage costs to record such
costs as incurred.  Previously, PECO accrued these costs over the operating unit
cycle. As a result of the change in accounting  method for nuclear outage costs,
PECO  recorded  income of $24 million,  net of income taxes of $16 million.  The
change is reported as a cumulative effect of a change in accounting principle on
the Consolidated  Statements of Income as of December 31, 2000, representing the
balance of the nuclear  outage cost  reserve at January 1, 2000.  On a pro forma
basis, Exelon reported net income for 1999 and 1998 would have been decreased by
$6 million,  or $0.03 per diluted share and  increased by $11 million,  or $0.05
per diluted share, respectively.



                                                                         Page 13


5. Regulatory Issues

ComEd
         In 2000,  the phased  process to implement  competition in the electric
industry continued as mandated by the requirements of the Illinois restructuring
legislation.

Customer Choice
         As of December 31, 2000, all non-residential customers were eligible to
choose a new electric  supplier or elect the purchase  power option which allows
the  purchase of  electric  energy from ComEd at  market-based  prices.  ComEd's
residential customers become eligible to choose a new electric supplier or elect
the  purchase  power option in May 2002.  As of December  31,  2000,  over 9,500
non-residential  customers,  representing  approximately  27% of ComEd's  retail
kilowatthour   sales  for  the  twelve  months  prior  to  the  introduction  of
open-access,  had elected to receive  their  electric  energy from a residential
electric  supplier or had chosen the purchase  power option.  ComEd is unable to
predict the long term impact of customer choice on results of operations.

Rate Reductions and Caps
         The Illinois restructuring  legislation also provided a 15% residential
base rate reduction  effective  August 1, 1998 with an additional 5% residential
base rate reduction to be implemented in October 2001.  Notwithstanding the rate
reduction and subject to certain earnings tests, a rate freeze will generally be
in effect until at least  January 1, 2005. A utility may request a rate increase
during the rate  freeze  period  only when  necessary  to ensure  the  utility's
financial viability. Under the Illinois restructuring legislation, if the earned
return on common equity of a utility  during this period  exceeds an established
threshold,  one-half of the excess  earnings must be refunded to customers.  The
threshold rate of return on common equity is based on the 30-Year  Treasury Bond
rate plus 8.5% in the years 2000 through 2004.  Earnings for purposes of ComEd's
rate cap include  ComEd's net income  calculated  in accordance  with  generally
accepted  accounting  principles  and may include  accelerated  amortization  of
regulatory assets and the amortization of goodwill.  As a result of the Illinois
restructuring  legislation,  ComEd has recorded a $385 million  regulatory asset
that it expects to fully recover and amortize by the end of 2003.  The utility's
earned  return on common  equity and the  threshold  return on common equity for
ComEd are each  calculated on a two-year  average  basis.  The earnings  sharing
provision is applicable only to ComEd's earnings.  ComEd did not trigger in 2000
and does not currently expect to trigger the earnings sharing  provisions of the
Illinois restructuring legislation in the years 2001 through 2004.

PECO
         In 2000,  the phased  process to implement  competition in the electric
industry   continued  as  mandated  by  the  requirements  of  the  PUC's  Final
Restructuring Order.

Customer Choice
         The PUC's  Final  Restructuring  Order  provided  for the  phase-in  of
customer  choice  of  electric  generation  supplier  (EGS)  for all  customers:
one-third of the peak load of each customer class on January 1, 1999;  one-third
on January 2, 1999;  and the remaining  one-third on January 1, 2000.  The Final
Restructuring  Order also  established  market share thresholds to ensure that a
minimum number of residential and commercial  customers  choose an EGS or a PECO
affiliate. If less than 35% and 50% of residential and commercial customers have
chosen an EGS, including  residential customers assigned to an EGS as a provider
of last  resort  default  supplier,  by  January  1, 2001 and  January  1, 2003,
respectively, the number of customers sufficient to meet the necessary threshold
levels   shall  be  randomly   selected   and  assigned  to  an  EGS  through  a
PUC-determined  process.  On January 1, 2001,  the 35% threshold was met for all
three  customer  classes as a result of  agreements  assigning  customers to New
Power Company and Green Mountain as providers of last resort default service. At
December 31, 2000,  approximately  18% of PECO's  residential  load,  46% of its
commercial load and 42% of its industrial  load were purchasing  generation from
an alternative generation supplier.


                                                                         Page 14


Rate Reductions and Caps
         Under the Final Restructuring  Order, retail electric rates were capped
at year-end 1996 levels (system-wide  average of 9.96 cents/kilowatt hour (kWh))
through June 2005.  The Final  Restructuring  Order  required PECO to reduce its
retail electric rates by 8% from the 1996 system-wide average rate on January 1,
1999.  This rate  reduction  decreased to 6% on January 1, 2000 until January 1,
2001.  The  transmission  and  distribution  rate  component  were  capped  at a
system-wide average rate of 2.98 cents/kWh through June 30, 2005.  Additionally,
generation rate caps, defined as the sum of the applicable transition charge and
energy and capacity charge, will remain in effect through 2010.

         On  March  16,  2000,  the PUC  issued  an  order  authorizing  PECO to
securitize  up to an  additional  $1 billion of its  authorized  stranded  costs
recovery.  In  accordance  with the terms of that order,  PECO will  provide its
retail  customers  with  rate  reductions  in the total  amount  of $60  million
beginning on January 1, 2001. This rate reduction will be effective for calendar
year 2001 only.

         Under a comprehensive settlement agreement in connection with achieving
regulatory  approval of the Merger  Transaction,  PECO agreed to $200 million in
rate  reductions  for all customers in  Pennsylvania  over the period January 1,
2002  through  2005  and  extended  the  rate  caps on  PECO's  retail  electric
distribution charges through December 31, 2006.

Prior to the merger, Unicom entered into a like-kind exchange transaction. Under
the  transaction,   Unicom  invested   approximately  $1.6  billion  in  passive
generating  station leases with two separate entities.  The generating  stations
were leased  back to such  entities as part of the  transaction.  For  financial
accounting purposes, the investments are accounted for as direct financing lease
investments.  Under  the  terms  of the  lease  agreements,  Exelon  received  a
prepayment of $1.2 billion in the fourth  quarter,  which reduced the investment
in the lease.  There are no minimum scheduled lease payments to be received over
the  next  five  years.  The  components  of the net  investment  in the  direct
financing leases as of December 31, 2000 are as follows:

Total minimum lease payments                   $1,492

         At December 31, 2000 and 1999, the Competitive  Transition Charge (CTC)
includes the unamortized balance of $4.8 billion and $3.9 billion, respectively,
of Intangible  Transition  Property (ITP) sold to PECO Energy  Transition  Trust

7. Earnings Per Share

         Diluted earnings per share are calculated by dividing net income by the
weighted  average shares of common stock  outstanding  including shares issuable
upon exercise of stock options  outstanding  under  Exelon's  stock option plans
considered to be common stock equivalents.  The following table shows the effect
of these stock options on the weighted average number of shares outstanding used
in calculating diluted earnings per share (in millions):

8. Accounts Receivable

         Accounts  receivable -- Customer at December 31, 2000 and 1999 included
unbilled operating revenues of $498 million and $153 million,  respectively. The
allowance  for  uncollectible  accounts at  December  31, 2000 and 1999 was $200
million and $112 million, respectively.

         Accounts  receivable  -- Other at December  31, 2000 and 1999  included
demand notes receivable from a  communications  investment in the amount of $153
million.  The average  interest rate on the notes receivable was 6.22% and 5.66%
at December  31, 2000 and 1999,  respectively.  Interest  income  related to the
notes receivable was $10 million and $6 million in 2000 and 1999, respectively.

         PECO is party to an agreement with a financial  institution under which
it can sell or finance with limited  recourse an  undivided  interest,  adjusted
daily, in up to $225 million of designated  accounts  receivable  until November
2005.  At December 31, 2000,  PECO had sold a $225 million  interest in accounts
receivable,  consisting of a $185 million interest in accounts  receivable which
PECO accounted for as a sale under SFAS No. 125,  "Accounting  for Transfers and
Servicing of Financial  Assets and  Extinguishment  of  Liabilities,"  and a $40
million interest in  special-agreement  accounts  receivable which was accounted
for as a long-term note payable.  See Note 12 - Long-Term Debt. PECO retains the
servicing  responsibility for these receivables.  The agreement requires PECO to
maintain the $225 million


                                                                         Page 17

such requirements.  At December 31, 2000 and 1999, PECO met this requirement and
was not required to make any cash deposits.

         Exelon's undivided  ownership  interests are financed with Exelon funds
and,  when  placed in  service,  all  operations  are  accounted  for as if such
participating interests were wholly owned facilities.

additional 7.51% ownership  interest in Peach Bottom Atomic Power Station (Peach
Bottom) from Atlantic City Electric  Company and Delmarva  Power & Light Company
for $18 million. On December 24, 2000, Exelon completed the purchase of Delmarva
Power & Light  Company's  3.755%  interest in Peach  Bottom for $9 million.  The
purchase of Atlantic City Electric Company's ownership interest is still pending
regulatory approval which is expected in 2001.

was $161 million and $142 million,  respectively.  At December 31, 1999,  Exelon
had $21 million of borrowings on lines of credit.

         In October 2000, Exelon obtained a $1.25 billion term loan due June 30,
2001 to finance the cash  consideration  paid to former holders of Unicom common
stock in connection  with the Merger  Transaction and to finance the purchase of
its 49.9%  interest in Sithe in December  2000.  Interest  rates on the advances
from the credit facility are based on the London Interbank Offering Rate (LIBOR)
as of the date of the advance.  On December 31, 2000,  Exelon had $1,210 million
outstanding on this term loan which is also reflected in Notes Payable,  Bank on
the Consolidated  Balance Sheet. The average interest rate on this term loan for
the period it was outstanding in 2000 was 7.6%. Exelon expects to refinance this
term loan on or before its due date.

hedge accounting policy. At December 31, 2000 and 1999, the unamortized net gain
was $51 million and $71 million, respectively.

         In  accordance  with SFAS No.  71,  Exelon has  recorded a  recoverable
deferred  income tax asset of $632 million and $638 million at December 31, 2000
and 1999, respectively.  These balances are applicable only to regulated assets,
as a  result  of  the  discontinuance  of  SFAS  No.  71 for  Exelon's  electric
generation  operations.  These  recoverable  deferred  income taxes  include the
deferred  tax  effects  associated  principally  with  liberalized  depreciation
accounted for in accordance with the ratemaking  policies of the PUC and ICC, as
well as the revenue  impacts  thereon,  and assume  continued  recovery of these
costs in future rates.

         The Internal  Revenue Service is currently  auditing  certain  Exelon's
subsidiaries  federal tax returns for 1996 through 1999.  The current audits are
not  expected to have an adverse  impact on  financial  condition  or results of
operations of Exelon.


14. Retirement Benefits

         Exelon and its  subsidiaries  have defined  benefit  pension  plans and
postretirement  benefit  plans  applicable  to  essentially  all PECO and  ComEd
employees  and certain  employees of other  subsidiaries.  Benefits  under these
plans  reflect  each  employee's  compensation,  years  of  service  and  age at
retirement. Funding is based upon actuarially determined contributions that take
into  account  the amount  deductible  for income tax  purposes  and the minimum
contribution required under the Employee Retirement Income Security Act of 1974,
as  amended.   The  following  tables  provide  a   reconciliation   of  benefit
obligations, plan assets and funded status of the plans.

         Prior  service  cost is  amortized  on a  straight  line basis over the
average remaining service period of employees expected to receive benefits under
the plans.

         During 2000, costs were recognized for special termination  benefits in
connection with the enhanced retirement and severance benefits provided under to
employees  expected  to be  terminated  as a result of the  Merger  Transaction.
Special  termination  benefits of $217 million  represented  PECO's  accelerated
separation  and  enhancement  benefits of $96  million  and ComEd's  accelerated
liability  increase of $121  million  inclusive  of $96  million for  separation
benefits and $25 million for plan enhancements  under Exelon's MSP. In addition,
Exelon  recognized   settlement  and  curtailment  credits  of  $28  million  in
connection  with Exelon's MSP. During 1999, all retirees and  beneficiaries  who
began  receiving  benefit  payments  prior to  January  1, 1994  were  granted a
cost-of-living  adjustment  resulting in a $25 million increase in the projected
benefit  obligation.  During 1998, costs were recognized for special termination
benefits in connection  with the retirement  incentives  and enhanced  severance
benefits provided under the Early Retirement and Separation Program.


                                                                         Page 24


         Exelon  provides  certain health care and life  insurance  benefits for
retired  employees.  Exelon employees become eligible for these benefits if they
retire  from  Exelon  with ten years of  service.  Certain  benefits  for active
employees are provided by several  insurance  companies whose premiums are based
upon the benefits paid during the year.

         Additionally,  Exelon maintains a nonqualified  supplemental retirement
plan  which  covers  any  excess  pension  benefits  that  would be  payable  to
management  employees  under the  qualified  plan but which are  limited  by the
Internal  Revenue Code. The fair value of plan assets  excludes $24 million held
in a grantor trust as of December 31, 2000 for the payment of benefits under the
supplemental plan and $9 million held in a grantor trust as of December 31, 2000
for the payment of postretirement medical benefits.

         Exelon  sponsors  savings plans for the majority of its employees.  The
plans  allow  employees  to  contribute  a  portion  of their  pretax  income in
accordance  with  specified  guidelines.  Exelon  matches  a  percentage  of the
employee  contribution  up to  certain  limits.  The cost of  Exelon's  matching
contribution  to the savings  plans  totaled  $17  million,  $7 million,  and $7
million in 2000, 1999, and 1998, respectively.

         The securities  issued by the PECO trusts represent  Company  Obligated
Mandatorily  Redeemable  Preferred Securities of a Partnership (COMRPS) having a
distribution rate and liquidation value equivalent to the trust securities.  The
COMRPS are the sole assets of these  trusts and  represent  limited  partnership
interests  of PECO  Energy  Capital,  L.P.  (Partnership),  a  Delaware  limited
partnership.  Each holder of a trust's  securities  is entitled to withdraw  the
corresponding  number  of  COMRPS  from the  trust  in  exchange  for the  trust
securities  so held.  Each series of COMRPS is  supported  by PECO's  deferrable
interest subordinated debentures,  held by the Partnership,  which bear interest
at rates equal to the distribution rates on the related series of COMRPS.

         ComEd  Financing I and ComEd  Financing II are wholly owned  subsidiary
trusts of ComEd.  Each ComEd  trust's  sole assets are  subordinated  deferrable
interest  securities  issued by ComEd bearing  interest rates  equivalent to the
distribution rate of the related trust security.

         The  interest  expense  on  the  debentures  and  deferrable   interest
securities is included in Distributions on Preferred  Securities of Subsidiaries
in the Consolidated Statements of Income and is deductible for tax purposes.



16. Common Stock

         At December 31, 2000 and 1999, common stock without par value consisted
of 600,000,000 and 500,000,000 shares authorized and 319,005,112 and 181,271,692
shares outstanding, respectively.

Stock Repurchase
         In January 2000, in connection with the Merger Agreement,  PECO entered
into a forward  purchase  agreement to purchase $500 million of its common stock
from time to time.  Settlement of this forward purchase agreement was, at PECO's
election, on a physical, net share or net cash basis. In May 2000, PECO utilized
a portion of the proceeds from the  securitization of its stranded cost recovery
to physically  settle this agreement,  resulting in the repurchase of 12 million
shares of common stock for $496 million.  In connection  with the  settlement of
this  agreement,  PECO  received  $1 million  in  accumulated  dividends  on the
repurchased shares and paid $6 million of interest.

         During 1997, PECO's Board of Directors  authorized the repurchase of up
to 25 million shares of its common stock from time to time through  open-market,
privately  negotiated  and/or other types of transactions in conformity with the
rules of the SEC.  Pursuant to these  authorizations,  PECO entered into forward
purchase  agreements to be settled from time to time, at PECO's  election,  on a
physical,  net share or


                                                                         Page 26


net cash basis. PECO utilized the proceeds from the  securitization of a portion
of its stranded cost recovery in the first quarter of 1999, to physically settle
these agreements, resulting in the purchase of 21 million shares of common stock
for $696 million.  In connection with the settlement of these  agreements,  PECO
received $18 million in accumulated dividends on the repurchased shares and paid
$6 million of interest.

Stock-Based Compensation Plans
         Exelon  maintains  a  Long-Term   Incentive  Plan  (LTIP)  for  certain
full-time salaried employees and previously  maintained a broad-based  incentive
program for certain other  employees.  The types of long-term  incentive  awards
that have been  granted  under the LTIP are  non-qualified  options to  purchase
shares of Exelon's common stock and common stock awards.  The types of long-term
incentive awards that have been granted under the broad-based  incentive program
are  non-qualified  options to purchase  shares of  Exelon's  common  stock.  At
December 31, 2000,  there were 9,000,000  options  authorized for issuance under
the LTIP and  2,000,000  options  authorized  under  the  broad-based  incentive
program. Exelon uses the disclosure-only provisions of SFAS No. 123, "Accounting
for Stock-Based  Compensation." If Exelon elected to account for its stock-based
compensation plans based on SFAS No. 123, it would have recognized  compensation
expense of $60  million,  $10 million and $6 million,  for 2000,  1999 and 1998,
respectively. In addition, net income would have been $526 million, $560 million
and $494 million for 2000, 1999 and 1998,  respectively,  and earnings per share
would have been $2.58, $2.84 and $2.20 for 2000, 1999 and 1998, respectively.

         The  exercise  price of the stock  options is equal to the fair  market
value of the underlying stock on the date of option grant. Options granted under
the  LTIP  and  the  broad-based   incentive  program  become  exercisable  upon
attainment of a target share value and/or time. All options expire 10 years from
the date of grant.  Information  with  respect  to the LTIP and the  broad-based
incentive  program at  December  31,  2000 and  changes for the three years then
ended, is as follows:

         Exelon issued 195,725 shares, 120,300 shares and 7,000 shares of common
stock awards during 2000,  1999 and 1998,  respectively.  Vesting for the common
stock  awards  is over a period  not to exceed  10 years  from the  grant  date.
Compensation  cost of $9  million,  $5 million and $0.2  million,  respectively,
associated  with these awards is  amortized to expense over the vesting  period.
The related accumulated amortization was approximately $7 million and $2 million
at December 31, 2000 and 1999, respectively.

         Financial    instruments   which   potentially    subject   Exelon   to
concentrations  of credit  risk  consist  principally  of cash  equivalents  and
customer   accounts   receivable.   Exelon  places  its  cash  equivalents  with
high-credit quality financial institutions.  Generally,  such investments are in
excess of the Federal Deposit


                                                                         Page 29


Insurance  Corporation  limit.  Concentrations  of credit  risk with  respect to
customer  accounts  receivable  are  limited  due to  Exelon's  large  number of
customers and their dispersion across many industries.

         The fair value of derivatives  generally reflects the estimated amounts
that Exelon would  receive or pay to terminate  the  contracts at the  reporting
date, thereby taking into account the current unrealized gains or losses of open
contracts. Dealer quotes are available for all of Exelon's derivatives.

         Exelon  entered into interest rate swaps  relating to two variable rate
series of transition bonds in the aggregate notional amount of $1.1 billion with
an average interest rate of 6.65%. Exelon has also entered into forward starting
interest rate swaps relating to two variable rate series of transition  bonds in
the aggregate  notional amount of $1.1 billion with an average  interest rate of
6.01%.  In anticipation of the refinancing of a portion of the two variable rate
series of  transition  bonds in the first quarter of 2001,  Exelon  settled $318
million of the  forward  starting  interest  rate swaps in  December  2000.  The
notional  amount of derivatives  do not represent  amounts that are exchanged by
the  parties  and,  thus,  are not a measure of Exelon's  exposure.  The amounts
exchanged are  calculated on the basis of the notional or contract  amounts,  as
well as on the other terms of the  derivatives,  which relate to interest  rates
and the volatility of these rates.

         Exelon  would be  exposed  to  credit-related  losses  in the  event of
non-performance  by the counterparties  that issued the derivative  instruments.
Exelon does not expect that  counterparties to the interest rate swaps will fail
to meet these obligations,  given their high credit ratings. The credit exposure
of  derivatives  contracts is  represented by the fair value of contracts at the
reporting  date.  Exelon's  interest  rate  swaps are  documented  under  master
agreements.  Among other things,  these agreements  provide for a maximum credit
exposure for both parties.  Payments are required by the appropriate  party when
the maximum limit is reached.


18. Commitments and Contingencies

Capital Commitments
         Exelon  estimates  that it will spend  approximately  $2.7  billion for
capital  expenditures and other  investments in 2001.  Exelon has commitments to
provide  AmerGen with capital  contributions  equivalent  to 50% of the purchase
price of any acquisitions AmerGen makes in 2001. In addition, Exelon and British
Energy have each agreed to provide up to $100 million to AmerGen at any time for
operating expenses. See Note 3 - Acquisitions: AmerGen Energy Company, LLC.

Nuclear Insurance
         The  Price-Anderson  Act limits the liability of nuclear reactor owners
for claims that could arise from a single  incident.  The current  limit is $9.5
billion  and is subject to change to account for the  effects of  inflation  and
changes in the number of licensed  reactors.  Through its  subsidiaries,  Exelon
carries the  maximum  available  commercial  insurance  of $200  million and the
remaining  $9.3  billion  is  provided  through  mandatory  participation  in  a
financial  protection  pool. Under the  Price-Anderson  Act, all nuclear reactor
licensees can be assessed up to $89 million per reactor per incident, payable at
no more than $10 million per reactor per incident per year.  This  assessment is
subject to inflation and state premium  taxes.  In addition,  the U.S.  Congress
could impose revenue-raising measures on the nuclear industry to pay claims.

         Exelon  carries   property   damage,   decontamination   and  premature
decommissioning  insurance  for each station loss  resulting  from damage to its
nuclear plants.  In the event of an accident,  insurance  proceeds must first be
used for reactor stabilization and site decontamination. If the decision is made
to  decommission  the  facility,  a portion of the  insurance  proceeds  will be
allocated  to a  fund,  which  Exelon  is  required  by the  Nuclear  Regulatory
Commission  (NRC) to  maintain,  to provide for  decommissioning  the  facility.
Exelon is unable to predict the timing of the availability of insurance proceeds
to Exelon and the amount of such proceeds  which would be  available.  Under the
terms of the various  insurance  agreements,  Exelon could be assessed up to $69
million for losses  incurred at any plant  insured by the  insurance


                                                                         Page 30


companies.  Exelon is  self-insured to the extent that any losses may exceed the
amount of insurance maintained. Such losses could have a material adverse effect
on Exelon's financial condition and results of operations.

         Additionally,  through  its  subsidiaries,  Exelon  is a  member  of an
industry mutual insurance company that provides replacement power cost insurance
in the event of a major accidental outage at a nuclear station.  The premium for
this coverage is subject to  assessment  for adverse loss  experience.  Exelon's
maximum share of any assessment is $18 million per year.

         In  addition,  Exelon  participates  in the American  Nuclear  Insurers
Master Worker Program,  which provides coverage for worker tort claims filed for
bodily injury caused by a nuclear  energy  accident.  This program was modified,
effective   January  1,  1998,   to  provide   coverage  to  all  workers  whose
"nuclear-related  employment" began on or after the commencement date of reactor
operations.  Exelon will not be liable for a retrospective assessment under this
new policy.  However,  in the event  losses  incurred  under the small number of
policies in the old program exceed accumulated  reserves,  a maximum retroactive
assessment of up to $50 million could apply.

Nuclear Decommissioning and Spent Fuel Storage
         Exelon's  current estimate of its nuclear  facilities'  decommissioning
cost is $6.9 billion.  Decommissioning  costs are recoverable  through regulated
rates.  Under rates in effect through  December 31, 2000,  Exelon  collected and
expensed  approximately  $46 million in 2000 from customers  which was accounted
for as a component of  depreciation  expense and  accumulated  depreciation  for
operating  units and regulatory  assets for retired units.  At December 31, 2000
and  1999,  $2.6  billion  and  $383  million,  respectively,  was  included  in
accumulated  depreciation.  In order to fund future  decommissioning  costs,  at
December  31,  2000 and  1999,  Exelon  held  $3.1  billion  and  $408  million,
respectively,  in trust  accounts  which are included as Investments in Exelon's
Consolidated  Balance Sheets and include both net unrealized and realized gains.
Net  unrealized  gains  of $539  million  and $45  million,  respectively,  were
recognized in accumulated  depreciation in Exelon's  Consolidated Balance Sheets
at December 31, 2000 and 1999,  respectively.  Net realized gains of $11 million
and $14 million were also  recognized in  accumulated  depreciation  in Exelon's
Consolidated Balance Sheets at December 31, 2000 and 1999, respectively.  Exelon
believes that the amounts being recovered from customers through regulated rates
and earnings on nuclear  decommissioning trust funds will be sufficient to fully
fund the unrecorded portion of its decommissioning obligation.

         In connection with the transfer of ComEd's nuclear generating  stations
to  Generation,  ComEd  asked  the ICC to  approve  the  continued  recovery  of
decommissioning  costs after the transfer.  On December 20, 2000, the ICC issued
an order  finding  that  the ICC has the  legal  authority  to  permit  ComEd to
continue to recover  decommissioning  costs from customers for the six-year term
of the power purchase  agreements  between ComEd and  Generation.  Under the ICC
order,  ComEd is  permitted to recover $73 million per year from  customers  for
decommissioning  for the years 2001 through  2004.  In 2005 and 2006,  ComEd can
recover up to $73 million annually,  depending upon the portion of the output of
the  former  ComEd  nuclear  stations  that  ComEd  purchases  from  Generation.
Subsequent to 2006, there will be no further recoveries of decommissioning costs
from  customers.  The ICC order also  provides  that any surplus funds after the
nuclear stations are decommissioned must be refunded to customers. The amount of
recovery  in the ICC  order is less than the $84  million  annual  amount  ComEd
recovered  in 2000.  The ICC order is currently  pending  appeal in the Illinois
Appellate Court.

         Under the Nuclear Waste Policy Act of 1982 (NWPA), the U.S.  Department
of Energy (DOE) is responsible for the selection and development of repositories
for, and the disposal of, spent nuclear fuel and  high-level  radioactive  waste
(SNF).  ComEd and PECO, as required by the NWPA, each signed a contract with the
DOE  (Standard  Contract) to provide for  disposal of SNF from their  respective
nuclear  generating  stations.  In  accordance  with the  NWPA and the  Standard
Contract,  ComEd and PECO pay the DOE one mill ($.001) per  kilowatthour  of net
nuclear  generation for the cost of nuclear fuel long-term storage and disposal.
This fee may be adjusted  prospectively  in order to ensure full cost  recovery.
The NWPA and the Standard  Contract  required the DOE to begin taking possession
of SNF generated by nuclear  generating units by no later than January 1998. The
DOE, however, failed to meet that deadline and its performance is


                                                                         Page 31


expected to be delayed significantly.  The DOE's current estimate for opening an
SNF facility is 2010.  This extended  delay in SNF acceptance by the DOE has led
to Exelon's consideration of additional dry storage alternatives.

         In July  1998,  ComEd  filed a  complaint  against  the  United  States
Government  (Government)  in the United States Court of Federal  Claims  (Court)
seeking to recover  damages caused by the DOE's failure to honor its contractual
obligation to begin disposing of SNF in January 1998. ComEd  subsequently  moved
for partial  summary  judgment on liability of its breach of contract  claim. In
August 2000, the United States Court of Appeals for the Federal  Circuit decided
two other  similar  cases against the  Government,  rejecting  the  Government's
jurisdictional  defense and granting  partial summary  judgment on liability for
the  plaintiff  utilities  in one of those  cases.  The Court  later  denied the
Government's request for rehearing. Following that ruling, ComEd and seven other
utility plaintiffs filed motions in their respective cases in the Court to set a
coordinated  discovery  schedule on damages.  On January 8, 2001, the Government
filed a motion to reassign  all of the SNF cases to one Court judge for purposes
of consolidating  the cases to address certain damage issues.  Those motions are
pending  before the Court.  ComEd has also  requested  that the Court  grant its
pending  summary  judgment  motion on  liability,  particularly  in light of the
Federal Circuit's decision in August 2000.

         In July 2000,  PECO entered into an agreement  with the DOE relating to
PECO's  Peach Bottom  nuclear  generating  unit to address the DOE's  failure to
begin removal of SNF in January 1998 as required by the Standard Contract. Under
that  agreement,  the DOE agrees to provide  PECO with  credits  against  PECO's
future  contributions  to the  Nuclear  Waste  Fund  over the next ten  years to
compensate  PECO for SNF storage costs  incurred as a result of the DOE's breach
of the contract.  The agreement also provides that, upon PECO's request, the DOE
will take title to the SNF and the  interim  storage  facility  at Peach  Bottom
provided  certain  conditions  are met. In November 2000,  eight  utilities with
nuclear power plants filed a Joint  Petition for Review against the DOE with the
United  States Court of Appeals for the Eleventh  Circuit  seeking to invalidate
that portion of the  agreement  providing  for credits to PECO  against  nuclear
waste fund  payments on the ground  that such  provision  is a violation  of the
NWPA. PECO has intervened as a defendant in that case, which is ongoing.

         The Standard  Contract  with the DOE also  requires that PECO and ComEd
pay the DOE a one-time fee  applicable  to nuclear  generation  through April 6,
1983. PECO's fee has been paid.  Pursuant to the Contract,  ComEd has elected to
pay the one-time fee of $277 million, with interest to the date of payment, just
prior to the first  delivery  of SNF to the DOE. As of December  31,  2000,  the
liability for the one-time fee with interest was $810 million.

Energy Commitments
         Exelon's  wholesale   operations  include  the  physical  delivery  and
marketing  of  power  obtained  through  its  generation  capacity,   and  long,
intermediate and short-term contracts. Exelon maintains a net positive supply of
energy and capacity,  through  ownership of generation assets and power purchase
and lease agreements,  to protect it from the potential  operational  failure of
one of  its  owned  or  contracted  power  generating  units.  Exelon  has  also
contracted for access to additional generation through bilateral long-term power
purchase  agreements.  These  agreements are firm  commitments  related to power
generation of specific  generation  plants and/or are  dispatchable  in nature -
similar to asset  ownership.  Exelon enters into power purchase  agreements with
the objective of obtaining  low-cost  energy supply sources to meet its physical
delivery   obligations  to  its  customers.   Exelon  has  also  purchased  firm
transmission  rights to ensure  that it has  reliable  transmission  capacity to
physically move its power supplies to meet customer  delivery needs.  The intent
and business  objective  for the use of its capital  assets and  contracts is to
provide Exelon with physical power supply to enable it to deliver energy to meet
customer  needs.  Except for hedging  purposes,  Exelon  does not use  financial
contracts in its wholesale marketing activities. In 2001, Exelon anticipates the
use of  financial  contracts to manage the risk  surrounding  trading for profit
activities.

         Exelon has entered into bilateral long-term contractual obligations for
sales  of  energy  to  load-serving  entities,   including  electric  utilities,
municipalities,  electric cooperatives, and retail load aggregators. Exelon also
enters  into  contractual  obligations  to deliver  energy to  wholesale  market
participants  who


                                                                         Pgae 32


primarily focus on the resale of energy  products for delivery.  Exelon provides
delivery of its energy to these  customers  through  access to its  transmission
assets or rights for firm transmission.

         In  addition,   Exelon  has  entered  into  long-term   power  purchase
agreements with Independent Power Producers (IPP) under which Exelon makes fixed
capacity  payments to the IPP in return for  exclusive  rights to the energy and
capacity of the generating units for a fixed period.  The terms of the long-term
power purchase  agreements  enable Exelon to supply the fuel and dispatch energy
from the plants.

         At December 31, 2000, Exelon had long-term commitments,  in millions of
megawatt-hours  (MWh) and dollars,  relating to the purchase and sale of energy,
capacity  and  transmission  rights from  unaffiliated  utilities  and others as
expressed in the following tables:

         In 1997, PECO entered into a power supply contract in Massachusetts. In
1999,  PECO  determined  that,  based  upon  anticipated  prices  of  energy  in
Massachusetts  through the remaining life of the power supply  contract,  it had
incurred a loss of approximately $36 million.

         PECO  entered  into a final  settlement  of  litigation  in  1999  that
resulted in a  restructuring  of power  purchase  agreements  between PECO and a
cogeneration  facility.  The  settlement  also required  PECO to contribute  its
partnership  interest in the  cogeneration  facility to the remaining  partners.
Accordingly,  PECO recorded a charge to earnings of $15 million for the transfer
of its partnership  interest which is recorded in Other Income and Deductions on
Exelon's Consolidated Statements of Income. The settlement also resolved related
litigation  with  Westinghouse  Power  Generation and the Chase  Manhattan Bank.
Subsequently,  in 1999, PECO revised its estimate for losses associated with the
cogeneration  facility power purchase agreements and reversed  approximately $26
million of reserves,  which consisted  principally of the remaining balance of a
reserve previously recognized in 1997.

Environmental Issues
         Exelon's  operations  have in the  past and may in the  future  require
substantial  capital  expenditures in order to comply with  environmental  laws.
Additionally,  under Federal and state environmental  laws, Exelon,  through its
subsidiaries,  is generally  liable for the costs of  remediating  environmental
contamination  of  property  now or  formerly  owned by Exelon  and of  property
contaminated by hazardous substances generated by Exelon.  Exelon owns or leases
a number of real estate  parcels,  including  parcels on which its operations or
the operations of others may have resulted in  contamination by substances which


                                                                         Page 33


are considered  hazardous  under  environmental  laws.  Exelon has identified 72
sites where  former  manufactured  gas plant (MGP)  activities  have or may have
resulted in actual site contamination.  Exelon is currently involved in a number
of proceedings  relating to sites where hazardous substances have been deposited
and may be subject to additional proceedings in the future.

         As of December  31, 2000 and 1999,  Exelon had accrued $172 million and
$57 million,  respectively,  for  environmental  investigation  and  remediation
costs,   including  $140  million  and  $32  million,   respectively,   for  MGP
investigation and remediation,  that currently can be reasonably estimated.  The
increases  were primarily  attributable  to the  acquisition  of Unicom.  Exelon
cannot reasonably  estimate whether it will incur other significant  liabilities
for additional  investigation and remediation costs at these or additional sites
identified by Exelon,  environmental  agencies or others,  or whether such costs
will be recoverable from third parties.

         Rental expense under operating leases totaled $41 million, $54 million,
and $69 million in 2000, 1999 and 1998, respectively.

Early Retirement and Separation Program
         At December  31,  1998,  PECO  incurred a charge of $125  million  ($74
million,  net of income taxes) for its Early  Retirement and Separation  Program
relating to 1,157  employees.  The  estimated  cost of  separation  benefits was
approximately $47 million.  Retirement benefits of approximately $78 million are
being paid to the retirees over their lives.  All cash  payments  related to the
Early Retirement and Separation Program were funded through the assets of PECO's
Service Annuity Plan. The Early Retirement and Separation  Program terminated on
June 30, 2000.

Litigation
         Cajun  Electric  Power  Cooperative,  Inc. On May 27, 1998,  the United
States  Department of Justice,  on behalf of the Rural Utilities Service and the
Chapter 11 Trustee for the Cajun Electric Power Cooperative, Inc. (Cajun), filed
an action claiming breach of contract against PECO in the United States District
Court for the Middle District of Louisiana arising out of PECO's  termination of
the contract to purchase Cajun's interest in the River Bend nuclear power plant.
This action seeks the full purchase  price of the 30% interest in the River Bend
nuclear plant, $50 million, plus interest and consequential  damages. While PECO
cannot  predict  the  outcome  of this  matter,  PECO  believes  that it validly
exercised its right of termination and did not breach the agreement.

         FERC Municipal Request for Refund. Three of ComEd's wholesale municipal
customers  filed a complaint  and request for refund with the FERC alleging that
ComEd failed to properly  adjust their rates, as provided for under the terms of
their  electric  service  contracts,  to track  certain  refunds made to ComEd's
retail  customers in the years 1992 through  1994. In the third quarter of 1998,
the FERC granted the complaint and directed that refunds be made, with interest.
ComEd filed a request for  rehearing.  On January 11, 2001,  the FERC issued its
Order on Rehearing Requesting Submission of Additional  Information.  Responsive
pleadings have been filed by all parties and final FERC action is still pending.
ComEd's  management  believes  an  adequate  reserve  has  been  established  in
connection with the case.

         Service Interruptions. In August 1999, three class action lawsuits were
filed,  and  subsequently  consolidated,  in the Circuit  Court of Cook  County,
Illinois seeking damages for personal injuries, property


                                                                         Page 34


damage  and  economic   losses  from  ComEd  related  to  a  series  of  service
interruptions  that  occurred in the summer 1999.  The combined  effect of these
interruptions  resulted in over 168,000 customers losing service for more than 4
hours.  Conditional  class  certification has been approved by the Court for the
sole purpose of exploring settlement talks. A hearing on a motion filed by ComEd
to dismiss the complaints is expected in March 2001. A portion of any settlement
or verdict  may be covered by  insurance  and  discussions  with the carrier are
ongoing. Exelon's management believes adequate reserves have been established in
connection with these cases.

         Reliability  Investigation. In 1999,  the ICC  opened an  investigation
regarding the design and reliability of ComEd's  transmission  and  distribution
system,  which was expanded  during 2000 to include a circuit  breaker fire that
occurred  in October  2000 at a ComEd  substation.  The ICC has  issued  several
reports in that  investigation  covering  the summer 1999 outages as well as the
transmission and distribution system. These reports include  recommendations and
an  implementation  timetable.  The  recommendations  are not legally binding on
ComEd,  however,  the ICC may enforce them through litigation.  Two more reports
are anticipated in early 2001, and the  investigation is expected to conclude by
mid-2001.  Since  summer  1999,  ComEd  has  devoted  significant  resources  to
improving the reliability of its transmission and distribution system.  Exelon's
management believes that the likelihood of a successful material claim resulting
from the investigation is remote.

         Retail Rate Law. In 1996, several developers of non-utility  generating
facilities filed litigation against various Illinois officials claiming that the
enforcement  against  those  facilities of an amendment to Illinois law removing
the entitlement of those facilities to state-subsidized payments for electricity
sold to ComEd after March 15, 1996  violated  their rights under the federal and
state constitutions, and against ComEd for a declaratory order that their rights
under their  contracts with ComEd were not affected by the amendment.  On August
4, 1999, the Illinois  Appellate Court held that the developers'  claims against
the state were premature,  and the Illinois Supreme Court denied leave to appeal
that ruling.  Developers of both facilities have since filed amended  complaints
repeating their  allegations that ComEd breached the contracts in question,  and
requesting  damages for such breach, in the amount of the difference between the
state-subsidized  rate  and  the  amount  ComEd  was  willing  to  pay  for  the
electricity. ComEd intends to vigorously contest this matter.

Pennsylvania Real Estate Tax Appeals
         Exelon  is  involved  in tax  appeals  regarding  two  of  its  nuclear
facilities,  Limerick (Montgomery County) and Peach Bottom (York County). Exelon
is also  involved  in the tax appeal for Three  Mile  Island  Unit No. 1 Nuclear
Generating  Facility  (Dauphin County) through AmerGen.  Exelon does not believe
the outcome of these  matters  will have a material  adverse  effect on Exelon's
results of operations or financial condition.

Other Tax Issues
         The Illinois Department of Revenue has issued a notice of tax liability
to ComEd alleging deficiencies in Illinois invested capital tax payments for the
years 1998-1997.  The alleged  deficiencies,  including  interest and penalties,
totaled  approximately  $54 million as of December 31, 2000. ComEd has protested
the notices,  and the matter is currently  pending.  Interest  will  continue to
accumulate on the alleged tax deficiencies.

General
         Exelon is involved in various other  litigation  matters.  The ultimate
outcome of such  matters,  while  uncertain,  is not expected to have a material
adverse effect on Exelon's financial condition or results of operations.

21. Subsequent Events

Restructuring
         During  January 2001,  Exelon  undertook a corporate  restructuring  to
separate Exelon's generation and other competitive businesses from its regulated
energy  delivery  business.  As part  of the  restructuring,  the  non-regulated
operations  and related  assets of ComEd and PECO were  transferred  to separate
subsidiaries of Exelon.  Restructuring will streamline the process for managing,
operating and tracking financial performance of each business segment.

PETT Refinancing
         On March 1, 2001,  Exelon  refinanced  $806  million of  floating  rate
Series  1999-A  Transition  Bonds  through the  issuance  by PETT of  fixed-rate
transition bonds.
