             EXELON GENERATION COMPANY, LLC AND SUBSIDIARY COMPANIES
          CONDENSED COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
      (Dollars in millions, except per share data, unless otherwise noted)

1. BASIS OF PRESENTATION (Exelon, ComEd, PECO and Generation)
         The accompanying consolidated financial statements as of March 31, 2003
and for the  three  months  then  ended are  unaudited,  but in the  opinion  of
management of Exelon Corporation (Exelon),  Commonwealth Edison Company (ComEd),
PECO Energy  Company  (PECO) and Exelon  Generation  Company,  LLC  (Generation)
include all adjustments that are considered necessary for a fair presentation of
their  respective  financial  statements.  All  adjustments  are  of  a  normal,
recurring  nature,  except  as  otherwise  disclosed.   The  December  31,  2002
consolidated  balance sheets were derived from audited financial  statements but
do not  include all  disclosures  required by  accounting  principles  generally
accepted in the United States of America (GAAP). Certain prior-year amounts have
been  reclassified  for comparative  purposes.  These  reclassifications  had no
effect on net income or shareholders' or member's equity.  These notes should be
read in  conjunction  with the Notes to  Consolidated  Financial  Statements  of
Exelon,  ComEd, PECO and Generation  included in or incorporated by reference in
ITEM 8 of their Annual Report on Form 10-K for the year ended December 31, 2002.


2. NEW ACCOUNTING  PRINCIPLES AND ACCOUNTING  CHANGES (Exelon,  ComEd,  PECO and
Generation)

Accounting Principles with a Cumulative Effect upon Adoption
SFAS No. 143

         Statement of Financial Accounting Standards (SFAS) No. 143, "Accounting
for  Asset   Retirement   Obligations"   (SFAS  No.  143)  provides   accounting
requirements for retirement obligations (whether statutory,  contractual or as a
result of principles of promissory estoppel) associated with tangible long-lived
assets.  Exelon,  ComEd, PECO and Generation were required to adopt SFAS No. 143
as of January 1, 2003. In Exelon's case, a significant  retirement obligation is
Generation's  obligation to decommission  its nuclear plants at the end of their
license lives  projected to be from 2029 through 2056.  These nuclear plants and
the related nuclear  decommissioning  trust fund investments were transferred to
Generation  by  ComEd  and  PECO  in  connection   with  the  Exelon   corporate
restructuring on January 1, 2001.

         Generation  had  decommissioning  assets of $3,053  million  and $3,032
million as of  December  31,  2002 and March 31,  2003,  respectively,  in trust
accounts.  Exelon and  Generation  anticipate  that all trust fund  assets  will
ultimately be used to decommission its nuclear plants.

         After considering  recent  interpretation of the transitional  guidance
included in SFAS No. 143,  Exelon  recorded income of $112 million (after income
taxes) as a cumulative effect of a change in accounting  principle in connection
with its adoption of this standard. The components of the cumulative effect of a
change in  accounting  principle,  after  income  taxes,  recorded  in the



                                       21





first quarter of 2003 are as follows:

         The cumulative effect of the change in accounting principle in adopting
SFAS No. 143 had no impact on PECO's income statement.

         The asset retirement  obligations  (ARO) were determined under SFAS No.
143  to be  $2,366  million  and  $2,363  million  for  Exelon  and  Generation,
respectively.  As  further  explained  below,  the  adoption  also  resulted  in
recording  regulatory  assets and  liabilities.  The following  table provides a
reconciliation  of the AROs  reflected on the balance sheet at December 31, 2002
and March 31, 2003:

         Determination of Asset Retirement Obligation

         In  accordance  with SFAS No. 143, a  probability-weighted,  discounted
cash flow model with  multiple  scenarios was used to determine the "fair value"
of the decommissioning  obligation. SFAS No. 143 also stipulates that fair value
represent the amount a third party would receive for assuming all of an entity's
obligation.

         The present value of future  estimated cash flows was calculated  using
credit-adjusted risk-free rates applicable to the various businesses in order to
determine the fair value of Exelon's  decommissioning  obligation at the time of
adoption of SFAS No. 143.

         Significant  changes in the assumptions  underlying the items discussed
above could materially affect the balance sheet amounts and future costs related
to decommissioning recorded in the Consolidated Financial Statements.

         Effect of adopting SFAS No. 143

          Exelon was required to re-measure the  decommissioning  liabilities at
fair value using the  methodology  prescribed  by SFAS No. 143.  The  transition
provisions of SFAS No. 143 required Exelon to apply this  re-measurement back to
the  historical  periods in which asset  retirement  obligations  were incurred,
resulting  in a  re-measurement  of these  obligations  at the date the  related
assets were acquired.  Since the nuclear plants  previously  owned by ComEd were
acquired by Exelon on the October 20,  2000  Merger  date,  Exelon's  historical
accounting for its ARO has been revised as if SFAS No. 143 had been in effect at
the Merger date.

         In the case of the former ComEd plants, the calculation of the SFAS No.
143  ARO  yielded  decommissioning  obligations  lower  than  the  value  of the
corresponding  trust  assets.   ComEd  has  previously  collected  amounts  from
customers  (which were  subsequently  transferred  to  Generation) in advance of
Generation's  recognition of decommissioning  expense, under SFAS No. 143. While
it is expected  that the trust assets will  ultimately  be used entirely for the
decommissioning of the plants, the current measurement  required by SFAS No. 143
shows an excess of assets over related ARO  liabilities.  As such, in accordance
with regulatory accounting practices and a December 2000 ICC Order, a regulatory
liability of $948 million and a  corresponding  receivable  from Generation were
recorded at ComEd upon the adoption of SFAS No. 143. Exelon believes that all of
the  decommissioning  assets,  including  the $73 million of annual  collections
through 2006, will be used to decommission the former ComEd plants.


                                       23


Accordingly, Exelon expects the regulatory liability and corresponding
receivable from Generation will be reduced to zero at the conclusion of the
decommissioning of the former ComEd plants.

         In the case of the former PECO plants, the SFAS No. 143 ARO calculation
yielded decommissioning obligations greater than the corresponding trust assets.
As such,  a  regulatory  asset of $20  million  and a  corresponding  payable to
Generation  were  recorded  upon  adoption  at PECO.  Exelon  also  expects  the
regulatory asset and corresponding payable to Generation will be reduced to zero
at the conclusion of the decommissioning of the former PECO plants.

         Prior  to the  adoption  of  SFAS  No.  143,  Generation's  Accumulated
Depreciation included $2,845 million for decommissioning  liabilities related to
the active plants.  This amount was  reclassified to an ARO upon the adoption of
SFAS No.  143.  Additionally,  Generation  adjusted  the  total  decommissioning
liability for the ComEd plants to $1,575 million and for the PECO plants to $787
million.  As  described  above,  Generation  recorded a payable to ComEd of $948
million and a receivable  from PECO of $20 million.  Generation also recorded an
Asset  Retirement Cost asset (ARC) of $172 million related to the  establishment
of the PECO ARO in accordance  with SFAS No. 143. The ARC will be amortized over
the remaining lives of the plants.

         As discussed above, Exelon re-measured its 2001 decommissioning related
balances  associated with the October 2000 Merger  purchase price  allocation at
ComEd and the January 2001 corporate  restructuring  as if SFAS No. 143 had been
in effect at the Merger date.  Exelon and ComEd  concluded that had SFAS No. 143
been in effect,  ComEd would not have recorded an  impairment on its  regulatory
asset for  decommissioning  of its retired  nuclear  plants as a purchase  price
allocation  adjustment  in 2001 as a result  of the  December  2000  ICC  order.
Increased net assets would have been  transferred  to Generation by ComEd in the
corporate restructuring. Accordingly, Exelon recorded a reduction of goodwill of
approximately  $210  million,  with a  corresponding  reduction  in its  overall
decommissioning obligation in connection with the implementation of SFAS No. 143
on January 1, 2003.  Similarly,  ComEd  recorded a reduction  of $210 million of
goodwill and of  shareholders'  equity,  and Generation  recorded a $210 million
increase in member's equity and a corresponding reduction of its decommissioning
obligation.  In addition,  Exelon and ComEd  recorded a  cumulative  effect of a
change in accounting  principle of $5 million to reverse  goodwill  amortization
that had been recorded in 2001.  Exelon and ComEd also reclassified a regulatory
asset related to nuclear decommissioning costs for retired units of $248 million
to regulatory liabilities.

         The following  tables set forth ComEd and  Generation's  net income and
Generation's income before cumulative effect of changes in accounting principles
for the three months  ended March 31, 2002  adjusted as if SFAS No. 143 had been
applied effective January 1, 2002.  ComEd's income before cumulative effect of a
change in accounting principle was not affected by the adoption of SFAS No. 143.

         Accounting methodology under SFAS No. 143

         For  the   former   ComEd   plants,   realized   gains  and  losses  on
decommissioning  trust funds are  reflected  in other income and  deductions  in
Generation's  Consolidated  Statements of Income, while the unrealized gains and
losses on  marketable  securities  held in the trust  funds  adjust the  payable
Generation  currently  has to ComEd.  The  increases  in the ARO are recorded in
accretion expense,  while the funds received from ComEd for  decommissioning are
recorded in revenue.  Generation's  payable to ComEd will be adjusted to reflect
the difference between the  decommissioning  assets and the ARO levels. As such,
if the ARO  increases  at a rate  faster  than the  increase  in the trust  fund
assets,  ComEd's  regulatory  liability  and  receivable  from  Generation  will
decrease.  If and when the trust  assets  are  exceeded  by the  decommissioning
liability, Generation is responsible for any shortfall in funding. The result of
the  above  accounting  will be  adjusted  to  reflect  no  earnings  impact  to
Generation  for  as  long  as  the  trust  assets  exceed  the   decommissioning
liabilities for the former ComEd plants.

         The above  accounting  practices  are also  applicable  for former PECO
plants  owned by  Generation,  with the  addition  of the  depreciation  expense
Generation will recognize on the ARC established  upon adoption of SFAS No. 143.
However, as PECO has the expectation of full recovery of decommissioning  costs,
the result of the above  accounting  will be  adjusted  to  reflect no  earnings
impact to Generation.  Therefore,  to the extent that the net of decommissioning
revenues  collected  and realized  investment  income  differ from the accretion
expense to the  decommissioning  liability and the related  depreciation  of the
ARC, an  adjustment  to net the amounts to zero would be recorded by  Generation
for that period.

         The  ongoing   effects  to  Generation   for  the  accounting  for  the
decommissioning of the AmerGen Energy Company, LLC (AmerGen) plants are recorded
within Generation's equity in earnings of AmerGen.

SFAS No. 141 and SFAS No. 142

         In 2001, the FASB issued SFAS No. 141,  "Business  Combinations"  (SFAS
No. 141),  which requires that all business  combinations be accounted for under
the purchase  method of  accounting  and  establishes  criteria for the separate
recognition of intangible assets acquired in business combinations. SFAS No. 141
became  effective for business  combinations  initiated  after June 30, 2001. In
addition,  SFAS No. 141 required that unamortized  negative  goodwill related to
pre-July 1, 2001  purchases be recognized  as a change in  accounting  principle
concurrent  with the adoption of SFAS No. 142,  "Goodwill  and Other  Intangible
Assets" (SFAS No. 142). At December 31, 2001, AmerGen, an equity-method investee
of  Generation,  had  $43  million  of  negative  goodwill,  net of  accumulated
amortization, recorded on its balance sheet. Upon AmerGen's adoption of SFAS No.
141 in January 2002,  Generation recognized its proportionate share of income of
$22 million  ($13  million,  net of income  taxes) as a  cumulative  effect of a
change in accounting principle.

         Exelon,  ComEd, PECO and Generation  adopted SFAS No. 142 as of January
1, 2002.  SFAS No. 142  establishes  new accounting and reporting  standards for
goodwill  and  intangible  assets.  Other than  goodwill,  Exelon  does not have
significant other intangible assets recorded on its consolidated balance sheets.
As  of  December  31,  2001,  Exelon's  Consolidated  Balance  Sheets  reflected
approximately  $5.3  billion  in  goodwill  net  of  accumulated   amortization,
including $4.9 billion of net goodwill related to the October 20, 2000 merger of
Unicom  Corporation  (Unicom),  the former  parent  company  of ComEd,  and PECO
(Merger)  recorded on ComEd's  Consolidated  Balance Sheets,  with the remainder
related to Exelon Enterprises Company, LLC (Enterprises).  The first step of the
transitional  impairment  analysis  indicated  that  ComEd's  goodwill  was  not
impaired but that an impairment  did exist with respect to goodwill  recorded in
Enterprises'  reporting  units.  InfraSource  Inc.  (InfraSource),   the  energy
services  business  (Exelon  Services) and the  competitive  retail energy sales
business  (Exelon  Energy)  were  determined  to be  those  reporting  units  of
Enterprises  that  had  goodwill  allocated  to  them.  The  second  step of the
analysis, which compared the fair value of each of Enterprises' reporting units'
goodwill to the carrying value at December 31, 2001,  indicated a total goodwill
impairment  of $357  million  ($243  million,  net of income  taxes and minority
interest).  The  impairment  was recorded as a cumulative  effect of a change in
accounting principle in the first quarter of 2002.

         The components of the net  transitional  impairment  loss recognized in
the first  quarter  of 2002 as a  cumulative  effect  of a change in  accounting
principle are as follows:

         At March 31,  2003,  Exelon had  goodwill of $4.8 billion of which $4.7
billion  relates to ComEd and the  remaining  goodwill  relates to  Enterprises'
reporting  units.  Consistent  with SFAS No.  142,  the  remaining  goodwill  is
reviewed for  impairment on an annual basis,  or more


                                       26



frequently if significant events occur that could indicate an impairment exists.
ComEd and Enterprises perform their annual reviews in the fourth quarter of
their fiscal years. The annual update impairment review during the fourth
quarter of 2002 did not identify any goodwill impairment.

         In the  third  quarter  of 2002,  Exelon  and  Generation  adopted  the
provisions of FASB Emerging Issue Task Force (EITF) Issue No. 02-3,  "Accounting
for Contracts  Involved in Energy Trading and Risk Management  Activities" (EITF
02-3)  issued by the EITF in June 2002 that  requires  revenues and energy costs
related to energy trading contracts to be presented on a net basis in the income
statement.  Prior to adoption,  revenues from trading activity were presented in
Revenue and the energy costs related to energy  trading were presented as either
Purchased  Power  or  Fuel  expense  on  Exelon  and  Generation's  Consolidated
Statements of Income. For comparative  purposes,  energy costs related to energy
trading have been  reclassified  to revenue in the results of operations for the
three  months  ended March 31, 2002 to conform to the net basis of  presentation
required by EITF 02-3.

SFAS No. 146

         In July 2002,  the FASB  issued  SFAS No.  146,  "Accounting  for Costs
Associated  with Exit or  Disposal  Activities"  (SFAS No.  146).  SFAS No.  146
requires  that  the  liability  for  costs  associated  with  exit  or  disposal
activities be recognized when incurred,  rather than at the date of a commitment
to an exit or disposal plan. SFAS No. 146 is to be applied prospectively to exit
or disposal  activities  initiated after December 31, 2002. Exelon,  ComEd, PECO
and Generation's  results of operations were unaffected by the adoption SFAS No.
146.

FIN No. 45

         In November 2002, the FASB released FASB  Interpretation  (FIN) No. 45,
"Guarantor's  Accounting and Disclosure  Requirements for Guarantees,  Including
Indirect  Guarantees  of  Indebtedness  of Others" (FIN No. 45),  providing  for
expanded  disclosures  and  recognition of a liability for the fair value of the
obligation  undertaken  by the  guarantor.  Under  FIN No.  45,  guarantors  are
required  to  disclose  the  nature  of the  guarantee,  the  maximum  amount of
potential future  payments,  the carrying amount of the liability and the nature
and  amount  of  recourse  provisions  or  available  collateral  that  would be
recoverable by the guarantor.  Exelon,  ComEd,  PECO and Generation  adopted the
disclosure  requirements  under FIN No. 45, which were  effective  for financial
statements  for periods  ended after  December 15,  2002.  The  recognition  and
measurement  provisions of FIN No. 45 were  effective for  guarantees  issued or
modified  after  December 31,  2002.  The adoption of FIN No. 45 had no material
effect on Exelon, ComEd, PECO or Generation's results of operations. Liabilities
associated  with  guarantees  entered into during the first  quarter of 2003 are
reflected in Note 8 - Commitments and Contingencies.


                                       27


SFAS No. 148

         In  December  2002,  the FASB  issued  SFAS No.  148,  "Accounting  for
Stock-Based  Compensation  -  Transition  and  Disclosure - an amendment of FASB
Statement No. 123" (SFAS No. 148). SFAS No. 148 provides  alternative methods of
transition  for a voluntary  change to the fair value based method of accounting
for stock-based  employee  compensation and requires  disclosures in both annual
and  interim  financial  statements  regarding  the  method  of  accounting  for
stock-based compensation and the effect of the method on financial results. SFAS
No. 148 was  effective  for  financial  statements  for fiscal years ended after
December 15, 2002. Exelon adopted the additional disclosure requirements of SFAS
No. 148 and  continues  to account  for its  stock-compensation  plans under the
disclosure  only  provision  of  SFAS  No.  123,   "Accounting  for  Stock-Based
Compensation" (SFAS No. 123). The tables below show the effect on net income and
earnings  per share for Exelon and the effect on net income for ComEd,  PECO and
Generation  had Exelon  elected to account for  stock-based  compensation  plans
using the fair value  method under SFAS No. 123 for the three months ended March
31, 2003 and 2002:

FIN No. 46

         In January 2003, the FASB issued FIN No. 46, "Consolidation of Variable
Interest  Entities"  (FIN No. 46).  FIN No. 46 addresses  consolidating  certain
variable interest entities and applies immediately to variable interest entities
created  after January 31, 2003.  The impact,  if any, of adopting FIN No. 46 on
Exelon, ComEd, PECO and Generation's consolidated financial position, results of
operations and cash flows has not been determined.

  SFAS No. 149

         In April 2003,  the FASB issued SFAS No. 149,  "Amendment  of Statement
133 on Derivative  Instruments and Hedging  Activities" (SFAS No. 149). SFAS No.
149 amends and clarifies  financial  accounting  and  reporting  for  derivative
instruments,   including  certain  derivative   instruments  embedded  in  other
contacts,  and for  hedging  activities  under  SFAS No.  133,  "Accounting  for
Derivative Instruments and Hedging Activities" (SFAS No. 133). SFAS No. 149 also
amends  SFAS  No.  133  for  decisions  made  (1) as  part  of  the  Derivatives
Implementation  Group process that effectively  required  amendments to SFAS No.
133,  (2)  in  connection  with  other  FASB  projects  dealing  with  financial
instruments, and (3) in connection with implementation issues raised in relation
to the application of the definition of a derivative.

         SFAS No. 149 is effective for contracts  entered into or modified after
June 30, 2003, except as stated below, and for hedging relationships  designated
after June 30, 2003. In addition, except as stated below, all provisions of SFAS
No.  149 will be  applied  prospectively.

         The   provisions   of  SFAS  No.  149  that  relate  to  SFAS  No.  133
implementation  issues that have been  effective for fiscal  quarters that began
prior to June 15, 2003 should  continue to be applied in  accordance  with their
respective effective dates. In addition, certain provisions  relating to forward
purchases or sales of when-issued securities or other securities that do not yet
exist,  should be applied to both existing  contracts and new contracts  entered
into after June 30,


                                       29



2003. Exelon, ComEd, PECO and Generation are currently determining the impact of
the  adoption  of SFAS No.  149 on  their  financial  position  and  results  of
operations.

Change in Accounting Estimate
ComEd
         Effective July 1, 2002, ComEd lowered its depreciation rates based on a
depreciation  study  reflecting its significant  construction  program in recent
years, changes in and development of new technologies,  and changes in estimated
plant service lives since the last depreciation study. The annualized  reduction
in  depreciation  expense,  based on  December  31,  2001  plant  balances,  was
estimated to be approximately $100 million ($60 million, after income taxes). As
a result of the  change,  net income for the three  months  ended March 31, 2003
increased approximately $24 million ($14 million, after income taxes).


3. ACQUISITIONS AND DISPOSITIONS (Exelon and Generation)
Sithe New England Holdings Acquisition

         On  November  1,  2002,  Generation  purchased  the assets of Sithe New
England Holdings,  LLC (currently known as Exelon New England),  a subsidiary of
Sithe Energies, Inc. (Sithe), and related power marketing operations. Exelon New
England's primary assets are gas-fired  facilities currently under construction.
The purchase price for the Exelon New England assets consisted of a $534 million
note to Sithe,  $14  million  of  direct  acquisition  costs and a $208  million
adjustment  to  Generation's  investment in Sithe related to Exelon New England.
Additionally,  Generation assumed various Sithe guarantees. Generation's assumed
guarantees are related to an equity  contribution  agreement  between Exelon New
England and Sithe  Boston  Generating,  LLC  (currently  known as Exelon  Boston
Generating,  LLC (EBG)), a project subsidiary of Exelon New England.  The equity
contribution  agreement  requires,  among other things, that Exelon New England,
upon the  occurrence of certain  events,  contribute up to $38 million of equity
for the purpose of completing the construction of two generating facilities. EBG
has a $1.25  billion  credit  facility  (EBG  Facility),  which was entered into
primarily to finance the  construction of these two generating  facilities.  The
$1.0 billion of debt outstanding  under the credit facility at March 31, 2003 is
reflected on Exelon and  Generation's  Consolidated  Balance Sheets.  Exelon New
England owns 4,066 megawatts (MWs) of generation  capacity,  consisting of 1,645
MWs in  operation  and  2,421  MWs  under  construction.  Exelon  New  England's
generation facilities are located primarily in Massachusetts.



                                       30



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

- --------------------------------------------------------------------------------
Current Assets (including $12 million of cash acquired)            $       82
Property, Plant and Equipment                                           1,956
Deferred Debits and Other Assets                                           62
Current Liabilities                                                      (159)
Deferred Credits and Other Liabilities                                   (149)
Long-Term Debt                                                         (1,036)
- --------------------------------------------------------------------------------
Total Purchase Price                                               $      756
================================================================================

         The purchase price has been adjusted in the first quarter of 2003 for a
$64 million  reclassification from Generation's investment in Sithe to property,
plant and equipment.

         The EBG Facility provides that if these  construction  projects are not
completed by June 12, 2003,  the EBG Facility  lenders will have the right,  but
will  not  be  required  to,  among  other  things,  declare  all  amounts  then
outstanding  under the EBG  Facility to be due, to terminate  the interest  rate
swap agreements, foreclose on all the pledged assets or ownership of the project
subsidiaries,  or require that all cash held by the project subsidiaries be used
to  reduce  the  debt.  An event of  default  under  the EBG  Facility  does not
constitute an event of default under any other debt instruments of Exelon or its
subsidiaries.  Generation  believes  that  the  construction  projects  will  be
substantially  complete by June 12, 2003, but that all of the  requirements  may
not be met by that date. However,  Generation  continues to monitor and evaluate
its  construction  progress as to whether the  requirements  of the EBG Facility
relating  to the  construction  projects  can be  satisfied  by June  12,  2003.
Generation  currently  expects that  arrangements for amendments or waivers,  if
necessary, can be negotiated with the EBG Facility lenders in the event that the
requirements are not satisfied by June 12, 2003.

Acquisition of Generating Plants from TXU

         On April 25, 2002,  Generation  acquired two  natural-gas and oil-fired
plants from TXU Corp. (TXU) for an aggregate purchase price of $443 million. The
purchase included the 893-MW Mountain Creek Steam Electric Station in Dallas and
the 1,441-MW  Handley  Steam  Electric  Station in Fort Worth.  The  transaction
included a purchased power agreement for TXU to purchase power during the months
of May through  September from 2002 through 2006.  During the periods covered by
the purchased  power  agreement,  TXU has agreed to fixed  capacity and variable
expense  payments,  and to provide fuel to Exelon in return for exclusive rights
to the energy and capacity of the generation  plants.  Substantially  all of the
purchase price has been allocated to property, plant and equipment.

Sale of AT&T Wireless

         On April 1, 2002,  Enterprises  sold its 49% interest in AT&T  Wireless
PCS of  Philadelphia,  LLC to a subsidiary  of AT&T  Wireless  Services for $285
million in cash. Enterprises recorded a gain of $201 million ($116 million after
income taxes) in Other Income and Deductions on Exelon's Consolidated Statements
of Income.


                                       31




4.  REGULATORY ISSUES (Exelon and ComEd)
         On March 3, 2003, ComEd entered into an agreement with various Illinois
electric retail market suppliers,  key customer groups and governmental  parties
regarding   several  matters   affecting  ComEd's  rates  for  electric  service
(Agreement).  The Agreement  addressed,  among other things,  issues  related to
ComEd's  residential  delivery  services  rate  proceeding,  market  value index
proceeding,  the process for  competitive  service  declarations  for large-load
customers  and  an  extension  of  the  purchased  power  agreement  (PPA)  with
Generation.  The parties to the Agreement agreed to make and support a series of
coordinated  filings  intended  to lead  to the  issuance  by the ICC of  orders
consistent  with the  Agreement.  Those  orders,  which were issued on March 28,
2003, are subject to rehearing. Rehearing requests have been filed with the ICC.
Rehearing  requests  may be  considered  through  the  middle of May  2003.  The
Agreement will not become effective as long as any of the ICC orders are subject
to any pending  rehearing  request or if a stay is issued with respect to any of
those orders.

         During the first quarter of 2003,  ComEd recorded a charge to earnings,
associated  with the funding of specified  programs and  initiatives  associated
with the Agreement, of $51 million on a present value basis before income taxes.
This amount is partially  offset by the reversal of a $12 million (before income
taxes) reserve  established in the third quarter of 2002 for a potential capital
disallowance in ComEd's delivery  services rate proceeding,  and a credit of $10
million  (before  income  taxes)  related  to  the  capitalization  of  employee
incentive payments provided for in the delivery services order. The net one-time
charge for these items was $29 million (before income taxes).


5.  EARNINGS PER SHARE (Exelon)
         Diluted earnings per share are calculated by dividing net income by the
weighted average number of 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):

                                           Three Months Ended March 31,
                                           ----------------------------

Average Dilutive Common Shares Outstanding      326              323
================================================================================

         There were five million  stock  options not included in average  common
shares used in calculating  diluted earnings per share due to their antidilutive
effect for the three months ended March 31, 2003 and 2002.

6. SEGMENT INFORMATION (Exelon, ComEd, PECO and Generation)
         Exelon operates in three business segments:  energy delivery (including
ComEd and  PECO),  generation  (includes  Generation)  and  enterprises.  Exelon
evaluates the  performance of its business  segments on the basis of net income.
ComEd, PECO and Generation each operate in a single business  segment.  Exelon's
segment  information  for the three  months ended March 31, 2003 and 2002 and at
March 31, 2003 and December 31, 2002 is as follows:

7. FAIR VALUE OF  FINANCIAL  ASSETS AND  LIABILITIES  (Exelon,  ComEd,  PECO and
Generation)
         During the three months ended March 31, 2003 and 2002,  Exelon recorded
pre-tax  gains  and  (losses)  in  other   comprehensive   income   relating  to
mark-to-market  (MTM) adjustments of contracts designated as cash flow hedges as
follows:




                                            ComEd         PECO     Generation    Enterprises      Exelon
- ---------------------------------------------------------------------------------------------------------
                                                                        
Three months ended March 31, 2003     $       1     $      3        $  (294)      $    4     $    (286)

- ---------------------------------------------------------------------------------------------------------



         Generation  recognized net MTM losses on non-trading  energy derivative
contracts not designated as cash flow hedges, in Purchased Power on Generation's
Consolidated  Statements of


                                       33



Income of $31 million  during the three months ended March 31, 2003 and gains of
$6 million during the three months ended March 31, 2002.

         Generation  recognized net MTM losses on proprietary  trading contracts
in earnings of $2 million  during the three  months ended March 31, 2003 and net
MTM gains of $1 million during the three months ended March 31, 2002.

         During the three months ended March 31, 2003 and 2002,  no amounts were
reclassified  to other  income in the  Consolidated  Statements  of  Income  and
Comprehensive  Income as a result  of the  discontinuance  of cash  flow  hedges
related  to  certain  forecasted  financing  transactions  that  were no  longer
probable of occurring.

         During the three months ended March 31, 2003 and 2002,  Generation  did
not  reclassify any amounts from  accumulated  other  comprehensive  income into
earnings as a result of forecasted energy commodity transactions no longer being
probable.

         As of  March  31,  2003,  deferred  net  gains/(losses)  on  derivative
instruments  accumulated in other  comprehensive  income that are expected to be
reclassified to earnings during the next twelve months are as follows:




                                                             ComEd      PECO      Generation     Enterprises    Exelon
- -----------------------------------------------------------------------------------------------------------------------
                                                                                              
Net Gains (Losses) Expected to be Reclassified              $   --     $  14      $  (364)       $     5     $   (345)
- -----------------------------------------------------------------------------------------------------------------------



         Amounts in accumulated other  comprehensive  income related to interest
rate cash  flow  hedges  are  reclassified  into  earnings  when the  forecasted
interest  payment  occurs.  Amounts in accumulated  other  comprehensive  income
related to energy commodity cash flows are  reclassified  into earnings when the
forecasted purchase or sale of the energy commodity occurs.

           As of March 31,  2003,  ComEd  expects  to  amortize  during the next
twelve  months $7 million of  regulatory  assets for  settled  cash flow  swaps.
During the first  quarter  2003,  ComEd  reclassified  $51 million ($30 million,
after income taxes) from other  comprehensive  income to  regulatory  assets for
cash flow swaps settled during the quarter.

         ComEd has also entered into interest rate swaps to effectively  convert
$485 million in  fixed-rate  debt to floating  rate debt.  These swaps have been
designated as fair-value hedges as defined in SFAS No. 133, and as such, changes
in the fair value of the swaps will be recorded in earnings. However, as long as
the hedge  remains  effective,  changes  in the fair  value of the swaps will be
offset by changes in the fair value of the hedged liabilities. Any change in the
fair  value of the  hedge  as a  result  of  ineffectiveness  would be  recorded
immediately in earnings. As of March 31, 2003, these swaps had an aggregate fair
market value of $42 million which was  classified as Other  Deferred  Debits and
Other Assets within the Consolidated Balance Sheets.

         Generation   classifies   investments   in  the  trust   accounts   for
decommissioning nuclear plants as available-for-sale.  The following tables show
the fair values,  gross unrealized gains and losses and amortized cost bases for
the securities held in these trust accounts.

8. COMMITMENTS AND CONTINGENCIES (Exelon, ComEd, PECO and Generation)
         For information regarding capital commitments,  nuclear decommissioning
and spent fuel  storage,  see the  Commitments  and  Contingencies  and  Nuclear
Decommissioning  and  Spent  Fuel  Storage  Notes in the  Notes to  Consolidated
Financial  Statements of Exelon,  ComEd,  PECO and Generation for the year ended
December 31, 2002. See Note 4 - New Accounting Principles and Accounting Changes
for further discussion of nuclear decommissioning commitments and contingencies.

Environmental Liabilities

           As  of  March  31,   2003,   Exelon  had  accrued  $143  million  for
environmental   investigation  and  remediation  costs  that  currently  can  be
reasonably  estimated,  including $114 million for  manufactured gas plant (MGP)
investigation  and remediation.  Exelon has identified 71 sites where former MGP
activities have or may have resulted in actual site contamination.

         As of March 31, 2003,  ComEd had accrued $92 million for  environmental
investigation and remediation costs that currently can be reasonably  estimated.
This  reserve  included  $87  million  (discounted)  for MGP  investigation  and
remediation.

         As of March 31, 2003, PECO had accrued $37 million  (undiscounted)  for
environmental   investigation  and  remediation  costs  that  currently  can  be
reasonably   estimated,   including  $27  million  for  MGP   investigation  and
remediation.

         As of March 31, 2003, Generation had accrued $14 million (undiscounted)
for  environmental  investigation and remediation cost, none of which relates to
MGP investigation and remediation.

         Exelon,  ComEd,  PECO and Generation cannot predict the extent to which
they will incur other significant  liabilities for additional  investigation and
remediation  costs at these or  additional  sites  identified  by  environmental
agencies or others, or whether such costs may be recoverable from third parties.

====================================================================================================


 (1) Net  Capacity  Purchases  includes  Midwest  Generation  commitments  as of
     March 31, 2003.  On October 2, 2002, Generation notified Midwest Generation
     of  its  exercise  of  termination   options  under  the  existing  Collins
     Generating Station (Collins) PPA and Peaking Unit (Peaking) PPA. Generation
     exercised its  termination  options on 1,727 MWs in 2003 and 2004. In 2003,
     Generation  will take 1,778 MWs of option  capacity  under the  Collins and
     Peaking Unit  Agreements as well as 1,265 MWs of option  capacity under the
     Coal  Generation  PPA. Net Capacity  Purchases in 2004 include 3,474 MWs of
     optional  capacity from Midwest  Generation.  Net Capacity  Purchases  also
     include capacity sales to TXU under the PPA entered into in connection with
     the purchase of two generating  plants in April 2002, which states that TXU
     will purchase the plant output from May through September from 2002 through
     2006. The combined capacity of the two plants is 2,334 MWs.
(2)  Transmission  Rights Purchases  include  estimated  commitments in 2004 and
     2005 for  additional  transmission  rights that will be required to fulfill
     firm sales contracts.

         Additionally, Generation has the following energy commitments:

         In connection with the 2001 corporate restructuring, Generation entered
into a PPA with ComEd under which Generation has agreed to supply all of ComEd's
load  requirements  through 2004. Prices for this energy vary depending upon the
time of day and  month of  delivery.  During  2005 and  2006,  ComEd's  PPA is a
partial  requirements  agreement  under  which  ComEd will  purchase  all of its
required energy and capacity from  Generation,  up to the available  capacity of
the  nuclear  generating  plants  formerly  owned by ComEd  and  transferred  to
Generation.  Under the terms of the PPA, Generation is responsible for obtaining
any  required  transmission  service,  subject to ComEd's  obligation  to obtain
network  service over the ComEd  system.  The PPA also  specifies  that prior to
2005,  ComEd and Generation  will jointly  determine and agree on a market-based
price for energy  delivered  under the PPA for 2005 and 2006.  In the event that
the parties cannot agree to market-based  prices for 2005 and 2006 prior to July
1, 2004,  ComEd has the option of  terminating  the PPA  effective  December 31,
2004.  ComEd will obtain any additional  supply  required from market sources in
2005 and 2006, and subsequent to 2006, will obtain all of its supply from market
sources,  which  could  include  Generation.  The PPA for  2005  and 2006 may be
extended to a full requirements  contract as a result of the Agreement (See Note
4 - Regulatory Issues).

         In connection with the 2001 corporate restructuring, Generation entered
into a PPA with PECO  under  which  Generation  has  agreed to supply  PECO with
substantially  all of PECO's electric supply needs through 2010. Also, under the
restructuring,  PECO assigned its rights and


                                       37



obligations  under  various  PPAs  and fuel  supply  agreements  to  Generation.
Generation  supplies  power to PECO  from  the  transferred  generation  assets,
assigned PPAs and other market sources.

         Under  terms of the  2001  corporate  restructuring,  ComEd  remits  to
Generation any amounts  collected  from  customers for nuclear  decommissioning.
Under an agreement  effective  September  2001,  PECO remits to  Generation  any
amounts collected from customers for nuclear decommissioning.

         Securities  Litigation.  Between May 8 and June 14, 2002, several class
action  lawsuits were filed in the Federal  District Court in Chicago  asserting
nearly  identical  securities  law  claims  on behalf  of  purchasers  of Exelon
securities  between April 24, 2001 and September  27, 2001 (Class  Period).  The
complaints  allege that Exelon  violated  Federal  securities  laws by issuing a
series  of  materially  false and  misleading  statements  relating  to its 2001
earnings  expectations  during  the Class  Period.  The court  consolidated  the
pending cases into one lawsuit and has appointed two lead  plaintiffs as well as
lead counsel.

         On  October  1,  2002,  the  plaintiffs  filed a  consolidated  amended
complaint.   In  addition  to  the  original  claims,  this  complaint  contains
allegations of new facts and contains several new theories of liability.  Exelon
believes the lawsuit is without merit and is vigorously contesting this matter.

ComEd
         FERC Municipal Request for Refund. Three of ComEd's wholesale municipal
customers  filed a complaint  and request  for refund with FERC,  alleging  that
ComEd  failed to properly  adjust its rates,  as provided for under the terms of
the electric service contracts with the municipal customers and to track certain
refunds made to ComEd's retail  customers in the years 1992 through 1994. In the
third  quarter of 1998,  FERC granted the complaint and directed that refunds be
made,  with interest.  ComEd filed a request for  rehearing.  On April 30, 2001,
FERC issued an order  granting  rehearing in which it  determined  that its 1998
order  had been  erroneous  and  that no  refunds  were  due  from  ComEd to the
municipal  customers.  In August  2001,  each of the three  wholesale  municipal
customers  appealed the April 30, 2001 FERC order to the Federal  circuit court,
which  consolidated  the appeals for the purposes of briefing and decision.  The
Federal circuit court has stayed the proceedings pending settlement negotiations
among the parties. ComEd currently believes that the outcome of this matter will
not have a material impact on its results of operations or financial condition.

         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.  The  developers  also  filed  suit  against  ComEd  for a
declaratory judgment that their rights under their contracts with ComEd were not
affected  by the  amendment.  On  November  25,  2002,  the  court  granted  the
developers'  motions for summary


                                       38


judgment.  The judge also entered a permanent  injunction  enjoining  ComEd from
refusing to pay the retail rate on the grounds of the  amendment,  and  Illinois
from denying ComEd a tax credit on account of such purchases. ComEd and Illinois
have each  appealed  the  ruling.  ComEd  believes  that it did not  breach  the
contracts in question and that the damages  claimed far exceed any loss that any
project incurred by reason of its  ineligibility  for the subsidized rate. ComEd
intends to prosecute its appeal and defend each case vigorously.

         Service Interruptions. In August 1999, three class action lawsuits were
filed against ComEd, and subsequently consolidated, in the Circuit Court of Cook
County,  Illinois  seeking  damages for personal  injuries,  property damage and
economic  losses related to a series of service  interruptions  that occurred in
the summer of 1999. The combined effect of these interruptions  resulted in over
168,000  customers  losing service for more than four hours.  Conditional  class
certification  was  approved  by the court  for the sole  purpose  of  exploring
settlement.  ComEd filed a motion to dismiss the complaints.  On April 24, 2001,
the  court  dismissed  four of the five  counts  of the  consolidated  complaint
without prejudice and the sole remaining count was dismissed in part. On June 1,
2001, the plaintiffs filed a second amended consolidated complaint and ComEd has
filed an answer.  On December 5, 2002, a settlement  was reached,  pending court
approval,  whereby  ComEd will pay up to $8 million,  which  includes $4 million
paid to date. The settlement,  when approved, will release ComEd from all claims
arising from the 1999 power outages.  A portion of any settlement or verdict may
be covered by insurance.

Generation
         Cotter  Corporation  Litigation.  During  1989 and 1991,  actions  were
brought  in  Federal  and  state  courts  in  Colorado  against  ComEd  and  its
subsidiary,   Cotter  Corporation  (Cotter),  seeking  unspecified  damages  and
injunctive  relief based on allegations  that Cotter  permitted  radioactive and
other  hazardous  material  to be  released  from its mill into  areas  owned or
occupied by the plaintiffs,  resulting in property damage and potential  adverse
health effects. In 1994, a Federal jury returned nominal dollar verdicts against
Cotter on eight plaintiffs' claims in the 1989 cases, which verdicts were upheld
on appeal.  The remaining  claims in the 1989 actions were settled or dismissed.
In 1998,  a jury  verdict  was  rendered  against  Cotter  in favor of 14 of the
plaintiffs in the 1991 cases, totaling  approximately $6 million in compensatory
and punitive  damages,  interest and medical  monitoring.  On appeal,  the Tenth
Circuit Court of Appeals  reversed the jury  verdict,  and remanded the case for
new trial.  These  plaintiffs'  cases were  consolidated  with the  remaining 26
plaintiffs'  cases,  which  had not  been  tried.  The  consolidated  trial  was
completed  on June 28,  2001.  The jury  returned a verdict  against  Cotter and
awarded $16 million in various damages. On November 20, 2001, the District Court
entered an amended final  judgment  that included an award of both  pre-judgment
and post-judgment  interests,  costs, and medical monitoring expenses that total
$43 million.  In November 2000,  another trial involving a separate sub-group of
13  plaintiffs,  seeking $19 million in damages plus  interest was  completed in
Federal District Court in Denver. The jury awarded nominal damages of $42,500 to
11 of 13  plaintiffs,  but awarded no damages for any personal  injury or health
claims,  other than requiring Cotter to perform  periodic medical  monitoring at
minimal  cost.  Cotter  appealed  these  judgments to the Tenth Circuit Court of
Appeals.  On April 22, 2003,  the Tenth Circuit  Court of Appeals  reversed both
judgments  and  remanded  the cases for retrial.  Cotter  intends to  vigorously
defend each case.


                                       39



         On February 18, 2000, ComEd sold Cotter to an unaffiliated third party.
As part of the sale, ComEd agreed to indemnify Cotter for any liability incurred
by Cotter as a result of these  actions,  as well as any  liability  arising  in
connection  with the West Lake  Landfill  discussed  in the next  paragraph.  In
connection with Exelon's 2001 corporate  restructuring,  the  responsibility  to
indemnify  Cotter for any liability  related to these matters was transferred by
ComEd to Generation.

         The U.S. Environmental  Protection Agency (EPA) has advised Cotter that
it is potentially liable in connection with radiological contamination at a site
known as the West Lake Landfill in Missouri.  Cotter is alleged to have disposed
of  approximately  39,000 tons of soils mixed with 8,700 tons of leached  barium
sulfate at the site. Cotter,  along with three other companies identified by the
EPA as potentially responsible parties (PRPs), has submitted a draft feasibility
study addressing  options for remediation of the site. The PRPs are also engaged
in  discussions  with the State of Missouri and the EPA. The estimated  costs of
remediation  for  the  site  range  from $0 to $87  million.  Once a  remedy  is
selected,  it  is  expected  that  the  PRPs  will  agree  on an  allocation  of
responsibility for the costs.  Until an agreement is reached,  Generation cannot
predict its share of the costs.

         Raytheon  Arbitration.  In March 2001,  two  subsidiaries  of Sithe New
England  acquired in November  2002,  brought an action in the New York  Supreme
Court against Raytheon  Corporation  (Raytheon) relating to its failure to honor
its  guaranty  with  respect  to the  performance  of the  Mystic and Fore River
projects,  as a  result  of the  abandonment  of  the  projects  by the  turnkey
contractor.  In a related proceeding,  in May 2002, Raytheon submitted claims to
the  International  Chamber of Commerce Court of Arbitration  seeking  equitable
relief and damages for alleged  owner-caused  performance  delays in  connection
with  the  Fore  River  Power  Plant  Engineering,  Procurement  &  Construction
Agreement (EPC Agreement). The EPC Agreement,  executed by a Raytheon subsidiary
and  guaranteed  by  Raytheon,  governs the design,  engineering,  construction,
start-up,  testing  and  delivery  of an 800-MW  combined-cycle  power  plant in
Weymouth,  Massachusetts.  Raytheon recently amended its claim and now seeks 141
days of schedule relief (which would reduce Raytheon's liquidated damage payment
for late delivery by  approximately  $25 million) and additional  damages of $16
million.  Raytheon also has asserted a claim in the amount of approximately  $12
million  for loss of  efficiency  and  productivity  as a result  of an  alleged
constructive  acceleration.  Generation  believes  the Raytheon  assertions  are
without  merit  and is  vigorously  contesting  these  claims.  Hearings  by the
International Chamber of Commerce Court of Arbitration with respect to liability
were held in January and  February  2003. A decision on liability is expected to
be issued in May 2003 and, if  necessary,  additional  hearings  will be held on
damages in May and June of 2003.

         Clean  Air Act.  On June 1,  2001,  the EPA  issued  to EBG a Notice of
Violation  (NOV) and Reporting  Requirement  pursuant to Sections 113 and 114 of
the  Clean  Air  Act,  alleging  numerous  exceedances  of  opacity  limits  and
violations of opacity-related  monitoring,  recording and reporting requirements
at Mystic  Station in  Everett,  Massachusetts.  On  January  8,  2002,  the EPA
indicated  that it had  decided to  resolve  the NOV  through an  administrative
compliance  order and a judicial  civil penalty  action.  In March 2002, the EPA
issued and Sithe  Mystic  LLC, a wholly  owned  subsidiary  of EBG,  voluntarily
entered  a  Compliance  Order  and  Reporting  Requirement   (Compliance  Order)
regarding Mystic Station, under which Mystic Station installed


                                       40


new ignition  equipment on three of the four units at the plant.  Mystic Station
also undertook an extensive opacity  monitoring and testing program for all four
units at the plant to help  determine if  additional  compliance  measures  were
needed.  Pursuant to the requirements of the Compliance  Order, the EBG switched
three  of the  four  units  to a lower  sulfur  fuel  oil by June 1,  2002.  The
Compliance Order does not address civil  penalties.  By a letter dated April 21,
2003, the United States  Department of Justice notified EBG that, at the request
of the EPA, it intended to bring a civil penalty action, but also offered to the
opportunity  to  resolve  the  matter  through  settlement  discussions.  EBG is
pursuing settlement discussions with the EPA and the Department of Justice.

         Real  Estate  Tax  Appeals.  Generation  is  involved  in  tax  appeals
regarding  a number  of its  nuclear  facilities,  Limerick  Generating  Station
(Montgomery County, PA), Peach Bottom Atomic Power Station (York County, PA) and
Quad Cities Station (Rock Island County, IL). Generation is also involved in the
tax  appeal  for  Three  Mile  Island  (Dauphin  County,  PA)  through  AmerGen.
Generation  does not believe the outcome of these  matters  will have a material
adverse effect on Generation's results of operations or financial condition.

Exelon, ComEd, PECO and Generation
         Exelon,  ComEd,  PECO and  Generation  are  involved  in various  other
litigation matters. The ultimate outcome of such matters, as well as the matters
discussed above,  while  uncertain,  are not expected to have a material adverse
effect on their respective financial condition or results of operations.

(a)     Credit  Facility  -  Exelon,  along  with  ComEd,  PECO and  Generation,
        maintain a $1.5 billion  364-day credit  facility to support  commercial

        with Calumet Energy Team,  LLC.  ComEd will  reimburse  Chicago for any
        nonperformance  by Midwest  Generation  under the Capacity  Reservation
        Agreement. The fair value of


                                       43



        this guarantee  under FIN 45 of $4 million is included as a liability on
        Exelon and ComEd's Consolidated Balance Sheets.  Additional  information

        relating to  Generation's  directly owned plants that is not included in
        this amount.

Unconsolidated Equity Investments

         Generation is a 49.9% owner of Sithe and accounts for the investment as
an unconsolidated  equity  investment.  In the first quarter of 2003, Exelon and
Generation  recorded an impairment charge of $200 million before income taxes in
other income and deductions, associated  with a decline in the Sithe  investment
value,  which is considered to be other than temporary.  Exelon and Generation's
management considered various factors in the decision to record an impairment of
this investment,  including management's recent experience of exploring the sale
of its interest in Sithe.  The  discussions  surrounding the sale indicated that
the fair value of the Sithe  investment is below its book value, and as such, an
impairment  charge was required.  This impairment  reduced the book value of the
investment to $212 million at March 31, 2003.

         Generation  continues to be subject to a Put and Call  Agreement  (PCA)
that gives Generation the right to purchase (Call) the remaining 50.1% of Sithe,
and gives the other Sithe shareholders the right to sell (Put) their interest to
Generation.  If the Put option is exercised,  Generation  has the  obligation to
complete the purchase.

         The PCA  originally  provided  that  the Put and  Call  options  became
exercisable as of December 18, 2002 and expires in December 2005. However,  upon
Apollo Energy,  LLC's (Apollo)  purchase of Vivendi's  34.2% ownership and Sithe
management's  1% share,  Apollo  agreed to delay the  effective  date of its Put
right until June 1, 2003 and, if certain  conditions are met, until September 1,
2003.  There are also  certain  events  that could  trigger  Apollo's  Put right
becoming  effective  prior to June 1, 2003,  including  Exelon being  downgraded
below investment grade by Standard and Poor's Rating Group or Moody's  Investors
Service,  Inc.,  a stock  purchase  agreement  between  Exelon and Apollo  being
executed and subsequently terminated, or the occurrence of any event of default,
other  than  a  change  of  control,  under  certain  Exelon  or  Apollo  credit
agreements.  Depending on the triggering event,  Apollo's Put needs to be funded
within 18 or 30 days of the Put being  exercised.  There have been no changes to
the Put and Call terms with respect to Marubeni's remaining 14.9% interest.

         If Generation exercises its option to acquire the remaining outstanding
common  stock in Sithe,  or if all the  other  stockholders  exercise  their Put
rights,  the purchase price for Apollo's  35.2%  interest will be  approximately
$460  million,  growing  at a market  rate of  interest.  The


                                       44


additional 14.9% interest will be valued at fair market value subject to a floor
of $141 million and a ceiling of $290 million.

         If Generation  increases its ownership in Sithe to 50.1% or more, Sithe
may become a  consolidated  subsidiary  and Exelon  and  Generation's  financial
results may include  Sithe's  financial  results from the date of  purchase.  At
March 31,  2003,  Sithe had total  assets of $2.5  billion  (including  the $534
million note from  Generation) and total debt of $1.3 billion.  The $1.3 billion
of debt includes $625 million of subsidiary  debt incurred  primarily to finance
the construction of six new generating facilities,  $457 million of subordinated
debt,  $119  million of line of credit  borrowings,  $41  million of the current
portion of long-term debt and capital leases, $30 million of capital leases, and
excludes  $464  million of  non-recourse  project debt  associated  with Sithe's
equity  investments.  For the  three  months  ended  March 31,  2003,  Sithe had
revenues of $199 million.

Credit Contingencies

         Generation is a counterparty to Dynegy in various energy  transactions.
In early  July 2002,  the credit  ratings  of Dynegy  were  downgraded  to below
investment grade by two credit rating agencies. As of March 31, 2003, Generation
had a net receivable  from Dynegy of  approximately  $4 million and,  consistent
with the terms of the existing credit  arrangement,  has received  collateral in
support of this  receivable.  Generation  also has credit risk  associated  with
Dynegy through  Generation's equity investment in Sithe. Sithe is a 60% owner of
the  Independence  generating  station  (Independence),   a  1,040-MW  gas-fired
qualified  facility that has an  energy-only  long-term  tolling  agreement with
Dynegy,  with a related financial swap arrangement.  As of March 31, 2003, Sithe
had recognized an asset on its balance sheet related to the fair market value of
the  financial  swap  agreement  with Dynegy that is marked to market  under the
terms of SFAS No.  133.  If  Dynegy  is  unable  to  fulfill  the  terms of this
agreement,  Sithe  would be  required  to  impair  this  financial  swap  asset.
Generation  estimates,  as a 49.9%  owner of Sithe,  that the  impairment  would
result in an after-tax reduction of its earnings of approximately $13 million.

         In addition to the  impairment of the financial  swap asset,  if Dynegy
were unable to fulfill its  obligations  under the financial  swap agreement and
the tolling agreement, Generation may incur a further impairment associated with
Independence.

         Additionally,  the future economic value of AmerGen's PPA with Illinois
Power  Company,  a subsidiary of Dynegy,  could be impacted by events related to
Dynegy's financial condition.


                                       45



General

         On February 20, 2003,  ComEd entered into separate  agreements with the
City of Chicago (Chicago) and with Midwest Generation (Midwest Agreement). Under
the terms of the agreement with Chicago, ComEd will pay Chicago $60 million over
ten years ($6 million was paid during the first quarter of 2003) and be relieved
of a requirement,  originally transferred to Midwest Generation upon the sale of
ComEd's fossil stations in 1999, to build a 500-MW  generation  facility.  Under
the terms of the Midwest  Agreement,  ComEd will receive from Midwest Generation
$32 million,  $22 million of which was received  during the first  quarter 2003,
and  the  remainder  was  received   during  April  2003,  to  relieve   Midwest
Generation's obligation under the fossil sale agreement. Midwest Generation will
also assume from  Chicago a Capacity  Reservation  Agreement  which  Chicago had
entered into with Calumet  Energy Team,  LLC (CET),  which is effective  through
June 2012.  ComEd  will  reimburse  Chicago  for any  nonperformance  by Midwest
Generation under the Capacity  Reservation  Agreement and paid  approximately $2
million  for  amounts  owed to CET by  Chicago  at the  time the  agreement  was
executed.  In the first quarter of 2003, ComEd recorded a guarantee liability of
$4 million  under the  provisions  of FIN 45 related  to ComEd's  obligation  to
reimburse Chicago for any nonperformance by Midwest  Generation.  The net effect
of the  settlement  and the FIN 45 liability to ComEd will be amortized over the
remaining life of the franchise agreement with Chicago.

         ComEd  and  PECO  have  entered  into  several  agreements  with  a tax
consultant  related to the filing of refund  claims  with the  Internal  Revenue
Service (IRS).  The fees for these  agreements are contingent  upon a successful
outcome and are based upon a percentage of the refunds  recovered  from the IRS,
if any. As such,  ComEd and PECO would have  positive net cash flows  related to
these agreements if any fees are paid to the tax consultant. These potential tax
benefits  and  associated  fees could be  material  to the  financial  position,
results of  operations  and cash flows of ComEd and PECO.  ComEd and PECO cannot
predict the timing of the final resolution of these refund claims.


9. MERGER-RELATED COSTS (Exelon, ComEd, PECO and Generation)
         In association  with the Merger,  Exelon recorded  certain reserves for
restructuring  costs. The reserves  associated with PECO were charged to expense
pursuant  to EITF  Issue  94-3,  "Liability  Recognition  for  Certain  Employee
Termination  Benefits  and Other  Costs to Exit an Activity  (including  Certain
Costs Incurred in a Restructuring)";  while the reserves  associated with Unicom
Corporation were recorded as part of the application of purchase  accounting and
did  not  affect  results  of  operations,  consistent  with  EITF  Issue  95-3,
"Recognition of Liabilities in Connection with a Purchase Business Combination".

         At  December  31,  2002,   Exelon,   ComEd,  PECO  and  Generation  had
liabilities   of  $28  million,   $13  million,   $1  million  and  $7  million,
respectively,  for certain benefits such as outplacement services,  continuation
of health care  coverage and  educational  benefits  associated  with the merger
separation  plans.  At March 31,  2003,  Exelon,  ComEd,  PECO and  Generation's
applicable  liabilities were $15 million, $5 million, $1 million and $5 million,
respectively.



                                       46


10. LONG-TERM DEBT AND PREFERRED SECURITIES (Exelon, ComEd and PECO)
         On January 22, 2003,  ComEd issued $350 million of 3.70% First Mortgage
Bonds, due in 2008 and $350 million of 5.875% First Mortgage Bonds, due in 2033.
These  bond  issuances  were used to  refinance  long-term  debt  which had been
previously retired during the third and fourth quarters of 2002.

         On March  17,  2003,  ComEd  issued  $200  million  of trust  preferred
securities,  with an  annual  distribution  rate of 6.35%  that are  mandatorily
redeemable in 2033.

         On March 18, 2003,  ComEd  redeemed $236 million of its First  Mortgage
Bonds, at a redemption price of 103.863% of the principal  amount,  plus accrued
interest.  The bonds, which carried an interest rate of 8.375%,  were refinanced
with long-term debt issued on April 7, 2003.

         On March 20, 2003,  ComEd redeemed $200 million of its trust  preferred
securities at a redemption price of 100% of the principal  amount,  plus accrued
distributions.  The  preferred  securities,  which  carried an interest  rate of
8.48%, were refinanced with trust preferred securities as discussed below.

         During the three  months  ended March 31, 2003,  Exelon  Corporate  and
ComEd  retired $215 million and $52 million of  commercial  paper  classified as
long-term debt, respectively.

         In 2003, ComEd entered into  forward-starting  interest rate swaps with
an aggregate  notional  amount of $240 million to manage  interest rate exposure
associated with anticipated debt issuance.  In connection with the 2003 issuance
of First Mortgage Bonds,  forward-starting interest rate swaps with an aggregate
notional amount of $870 million were settled with net proceeds to counterparties
of $51 million  ($30  million,  after  income  taxes) that has been  deferred in
regulatory  assets and is being  amortized  over the life of the First  Mortgage
Bonds as an increase to interest expense.

         During the three months ended March 31, 2003, ComEd recorded prepayment
premiums of $9 million and net unamortized premiums, discounts and debt issuance
expenses of $23 million,  associated  with the early  retirement of debt in 2003
that have been deferred by ComEd in  regulatory  assets and will be amortized to
interest expense over the life of the related new debt issuance  consistent with
regulatory recovery.

         During the three months ended March 31, 2003,  PECO issued $250 million
of commercial  paper which has been  classified as long-term debt (see Note 14 -
Subsequent Events).


11. SALE OF ACCOUNTS RECEIVABLE (Exelon and PECO)
         PECO is party to an agreement,  which expires in November 2005,  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. As of March 31, 2003, PECO had sold a $225 million interest
in  accounts  receivable,  consisting  of a $158  million  interest  in


                                       47


accounts  receivable  that PECO  accounted  for as a sale  under  SFAS No.  140,
"Accounting for Transfers and Servicing of Financial Assets and  Extinguishments
of  Liabilities,  a  Replacement  of FASB  Statement  No. 125" and a $67 million
interest in special-agreement  accounts receivable which were accounted for as a
long-term  note  payable.  PECO retains the servicing  responsibility  for these
receivables.  The agreement requires PECO to maintain the $225 million interest,
which,  if not met,  requires  cash,  which would  otherwise be received by PECO
under this program,  to be held in escrow until the requirement is met. At March
31, 2003, PECO met this requirement.

(1)  Generation  has entered into PPAs dated  December 18, 2001 and November 22,
     1999 with AmerGen.  Under the 2001 PPA,  Generation  has agreed to purchase
     from  AmerGen all the energy  from Unit No. 1 at Three Mile Island  Nuclear
     Station from January 1, 2002 through December 31, 2014. Under the 1999 PPA,
     Generation  agreed to purchase from AmerGen all of the residual energy from
     Clinton Nuclear Power Station (Clinton) through December 31, 2002. The 1999
     PPA will be extended  through  2026.  In  accordance  with the terms of the
     AmerGen  partnership  agreement,  Generation  has agreed to  purchase  from

     to $75 million at an interest rate equal to the one-month London  Interbank
     Offering Rate plus 2.25%. In July 2002, the limit of the loan agreement was

     LIBOR plus 0.875%. Interest accrued on the note as of March 31, 2003 was $5
     million.

(4)  Under a service agreement dated March 1, 1999,  Generation provides AmerGen
     with certain operation and support services to the nuclear facilities owned
     by  AmerGen.  This  service  agreement  has an  indefinite  term and may be
     terminated  by  Generation  or AmerGen with 90 days notice.  Generation  is
     compensated for these services at cost.

(5)  Under a service  agreement  dated  December 18, 2000,  Generation  provides
     certain engineering and environmental  services for fossil facilities owned

ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

(Dollars in millions, unless otherwise noted)

EXELON CORPORATION
- ------------------

GENERAL

         Exelon  Corporation  (Exelon),  a  registered  public  utility  holding
company, through its subsidiaries, operates in three business segments:

o    Energy Delivery, whose businesses include the regulated sale of electricity
     and distribution and transmission  services by Commonwealth  Edison Company
     (ComEd) in northern Illinois and PECO Energy Company (PECO) in southeastern
     Pennsylvania and the sale of natural gas and distribution  services by PECO
     in the Pennsylvania counties surrounding the City of Philadelphia.

o    Generation,  consisting of Exelon Generation  Company,  LLC's  (Generation)
     owned and contracted for electric generating  facilities,  energy marketing
     operations,  and equity  interests  in Sithe  Energies,  Inc.  (Sithe)  and
     AmerGen Energy Company, LLC (AmerGen).

o    Enterprises,  consisting of Exelon Enterprises Company, LLC's (Enterprises)
     competitive  retail  energy  sales,  energy  and  infrastructure  services,
     communications and other investments (primarily weighted towards the energy
     services and retail services industries).

         See Note 6 of the Condensed  Combined Notes to  Consolidated  Financial
Statements for further segment information.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2003 Compared To Three Months Ended March 31, 2002

Net Income and Earnings Per Share

         Exelon's net income for the three months ended March 31, 2003 increased
$353 million,  compared to the same period in 2002.  Diluted earnings per common
share on the same  basis  increased  $1.09 per  share.  Net income for the three
months ended March 31, 2003 reflects  $112 million of income for the  cumulative
effect of a change  in  accounting  principle  as a result  of the  adoption  of
Financial  Accounting  Standards Board (FASB) Statement of Financial  Accounting
Standards (SFAS) SFAS No. 143, "Asset  Retirement  Obligations"  (SFAS No. 143),
while net income  for the three  months  ended  March 31,  2002  reflects a $230
million charge for the cumulative effect of a change in accounting  principle as
a result of the adoption of SFAS No. 142, "Goodwill and Other Intangible Assets"
(SFAS No.  142).  See Note 2 of the  Condensed  Combined  Notes to  Consolidated
Financial Statements for further information  regarding the adoption of SFAS No.
143 and SFAS No. 142.


                                       55



         Income Before Cumulative Effect of Changes in Accounting Principles for
the three months ended March 31, 2003 increased $11 million,  or 5%, compared to
the same period in 2002.  Diluted  earnings  per common  share on the same basis
increased  $0.04 per share,  or 5%. The  increase  in income  before  cumulative
effect of changes in  accounting  principles  reflects  an overall  increase  in
revenue net fuel due to colder weather  conditions  and increased  recoveries of
competitive  transition charges (CTCs),  reduced nuclear refueling outage costs,
reduced  depreciation  expense resulting from lower depreciation rates at Energy
Delivery,  and decreased interest expense. This increase was partially offset by
the impairment of an investment in Sithe  Energies,  Inc. held by Generation,  a
one-time charge at Energy  Delivery (see Note 4 of the Condensed  Combined Notes
to Consolidated  Financial  Statements) and increased  operating and maintenance
expenses at  Generation  due to plant  acquisitions  after the first  quarter of
2002.

Results of Operations by Business Segment

         Exelon  evaluates its  performance  on a business  segment  basis.  The

         The changes in Energy  Delivery's  revenue,  net of purchased power and
fuel  expense,  for the three months  ended March 31, 2003  compared to the same
period in 2002, included the following:

o    changes in customer rates resulting in an $82 million increase,

o    increases  in  weather  normalized  volumes  of $31  million as a result of
     increases  in the number of  customers  and  additional  average  usage per
     customer, primarily residential customers,

o    favorable  weather impacts of $78 million,  primarily the results of colder
     winter weather,

o    net  unfavorable  changes due to customer  choice of $8 million,  including
     ComEd's  customers  electing to purchase  energy  from  alternative  energy
     suppliers or electing  ComEd's Power  Purchase  Option  (PPO),  under which
     non-residential  customers can purchase  power from ComEd at a market-based
     rate,  partially  offset by  customers  returning  to PECO as their  energy
     supplier,

o    pricing changes  related to ComEd's PPA with Generation  resulting in a $17
     million decrease,

o    increase of $16 million in  purchases  under the ComEd PPA with  Generation
     related to decommissioning collections associated with the adoption of SFAS
     No. 143 in 2003,  which were not recorded in purchased  power in 2002, (see
     Note  2  of  the  Condensed   Combined  Notes  to  Consolidated   Financial
     Statements), and

o    higher PJM ancillary  purchased power charges resulted in a decrease of $17
     million.

         The changes in operating  income,  other than changes in revenue net of
purchased  power and fuel  expense,  for the three  months  ended March 31, 2003
compared to the same period in 2002, included the following:

o    a net  one-time  charge of $41 million in 2003 at ComEd as the result of an
     agreement described in Note 4 - Regulatory Issues,

o    reduction in depreciation expense of $24 million due to the impact of lower
     depreciation rates at ComEd effective July 1, 2002,

o    reduction   of   amortization   expense   of  $16   million   for   nuclear
     decommissioning  of retired plants at ComEd due to the adoption of SFAS No.
     143 (see Note 2 of the Condensed  Combined Notes to Consolidated  Financial
     Statements),

o    increased  depreciation  expense in 2003 of $10 million due to higher plant
     in service balances,


                                       57



o    lower corporate  allocations and executive severance costs partially offset
     by higher pension and postretirement  benefit costs totaling $10 million in
     2003, and

o    additional  gross receipts tax expense of $7 million  related to additional
     revenues  (gross  receipts  taxes are  recorded in Revenues and Taxes Other
     Than Income and have no net impact on operating income).

         The changes in income  before income taxes and  cumulative  effect of a
change  in  accounting  principle  for the three  months  ended  March 31,  2003
compared to the same period in 2002, included the following:

o        a decrease in interest expense of $25 million primarily attributable to
         less  outstanding  debt  and  refinancing  of  existing  debt at  lower
         interest rates, and
o        the  reversal  in 2003 of a $12 million  reserve for a potential  plant
         disallowance  as the  result  of an  agreement  described  in  Note 4 -
         Regulatory Issues.

         Energy  Delivery's  effective  income  tax rate was 37.1% for the three
months ended March 31, 2003, compared to 37.0% for the same period in 2002.

         Due to the adoption of SFAS No. 143, ComEd recorded  cumulative  effect
of a change in accounting  principle of $5 million,  net of income taxes, in the
three months ended March 31, 2003. See Note 2 of the Condensed Combined Notes to
Consolidated Financial Statements for further discussion of these effects.

(1)  Bundled revenue  reflects  deliveries to customers  taking electric service
     under  tariffed  rates,  which  include the cost of energy and the delivery
     cost  of the  transmission  and  the  distribution  of the  energy.  PECO's
     tariffed rates also include a CTC charge.
(2)  Unbundled  revenue  reflects  revenue  from  customers  electing to receive
     electric  generation service from an alternative energy supplier or ComEd's
     PPO.  Revenue  from  customers  choosing  an  alternative  energy  supplier
     includes a distribution  charge and a CTC. Revenues from customers choosing
     ComEd's PPO includes an energy  charge at market  rates,  transmission  and
     distribution  charges  and  a  CTC.   Transmission  charges  received  from
     alternative  energy  suppliers are included in wholesale and  miscellaneous
     revenue.
(3)  Wholesale and miscellaneous revenues include transmission revenue, sales to
     municipalities and other wholesale energy sales.

         The  differences  in three months ended March 31, 2003 electric  retail
revenues  as  compared  to the same  period  in 2002  were  attributable  to the

o    Weather. The demand for electricity is impacted by weather conditions. Very
     warm  weather  in summer  months and very cold  weather in other  months is
     referred  to as  "favorable  weather  conditions,"  because  these  weather
     conditions result in increased sales of electricity.


                                       60



     Conversely,  mild weather reduces demand.  The weather impact for the three
     months  ended March 31, 2003 was  favorable  compared to the same period in
     2002 as a result of colder winter weather in 2003.  Heating  degree-days in
     the ComEd and PECO  service  territories  were 17% higher  and 33%  higher,
     respectively, in 2003 as compared to 2002.

o    Rate  Changes.  The  increase  in  revenues  attributable  to rate  changes
     reflects  the  collection  of  additional  CTC's  in 2003 by  ComEd of $105
     million  due  to an  increase  in  the  number  of  customers  choosing  an
     alternative  energy  supplier and changes in the wholesale  market price of
     electricity,  net of  increased  mitigation  factors.  Increased  wholesale
     market prices decreased revenue received under ComEd's PPO by $23 million.

o    Volume.  Revenues from higher delivery  volume,  exclusive of the effect of
     weather,  increased  due to an increased  number of customers and increased
     usage  per  customer,   primarily  residential  and  large  commercial  and
     industrial customers.

o    Customer  Choice.  All ComEd and PECO customers have the choice to purchase
     energy from alternative  suppliers.  This affects revenues from the sale of
     energy but not revenue  from the  delivery of  electricity  since ComEd and
     PECO continue to deliver  electricity  that is purchased  from  alternative
     suppliers.  As of  March  31,  2003,  13% of  energy  delivered  to  Energy
     Delivery's  customers was provided by alternative  electric suppliers.  The
     decrease in electric retail revenues includes a decrease in revenues of $39
     million  from  customers  in Illinois  electing to purchase  energy from an
     alternative  retail  electric  supplier  (ARES) or ComEd's  PPO,  partially
     offset  by an  increase  in  revenues  of $19  million  from  customers  in
     Pennsylvania who selected or returned to PECO as their electric supplier.

              The  Pennsylvania   Utility   Commission's  (PUC)  Final  Electric
     Restructuring  Order established  market share thresholds (MST) for PECO to
     promote competition. The MST requirements provide that, if as of January 1,
     2003, less than 50% of residential and commercial  customers have chosen an
     alternative   electric  generation   supplier,   the  number  of  customers
     sufficient  to meet the MST shall be randomly  selected  and assigned to an
     alternative  electric generation supplier through a PUC determined process.
     On  January  1,  2003,  the number of  customers  choosing  an  alternative
     electric  generation  supplier did not meet the MST. In January 2003,  PECO
     submitted to the PUC a MST plan to meet the 50% threshold  requirement  for
     its commercial  customers,  which was approved by the PUC in February 2003.
     As of March 31,  2003,  an auction had been  completed  for the  commercial
     customers and the customer  enrollment  phase is currently in process.  The
     randomly selected customers will be transferred to the alternative electric
     generation  suppliers in May 2003,  if they do not choose the option to not
     participate  in the program.  In February  2003,  PECO filed a  residential
     customer  MST plan,  and on May 1, 2003,  the PUC  approved  the plan.  The
     approved plan provides for a two-step process with a total of up to 400,000
     residential  customers  being  assigned  to  winning  alternative  electric
     generation  supplier  bidders:  up to  100,000 in July  2003,  and  another
     300,000 in December 2003. Any customer  transferred would have the right to
     return to PECO at any time.  PECO does not expect the transfer of customers
     pursuant  to the MST  plan to have a  material  impact  on its  results  of
     operations, financial position or cash flows.

o    Weather.  The demand for gas is impacted by weather  conditions.  Very cold
     weather  in  non-summer  months  is  referred  to  as  "favorable   weather
     conditions,"  because these weather conditions result in increased sales of
     gas.  Conversely,  mild  weather  reduces  demand.  The weather  impact was
     favorable  compared to the prior year as a result of colder winter weather.
     Heating degree-days  increased 33% in the three months ended March 31, 2003
     compared to the same period in 2002.
o    Volume.  Exclusive of weather  impacts,  higher delivery  volume  increased
     revenue in the three  months  ended  March 31,  2003  compared  to the same
     period in 2002  resulting  from customer  growth.  Deliveries to customers,
     excluding  the effects of weather,  increased  5% in the three months ended
     March 31, 2003 compared to the same period in 2002.
o    Rate Changes.  The  favorable  variance in rates is  attributable  to a 15%
     increase in the  purchased gas  adjustment  by the PUC  effective  March 1,
     2003.  The average  rate per million  cubic feet for the three months ended
     March 31, 2003 was 9% higher than the rate in the same 2002 period.  PECO's
     gas rates are subject to periodic  adjustments  by the PUC and are designed
     to recover from or refund to customers the  difference  between actual cost
     of  purchased  gas and the amount  included in base rates and to recover or
     refund  increases or decreases in certain state taxes not recovered in base
     rates.

Results of Operations - Generation

         In the second quarter of 2002,  Generation  early adopted FASB Emerging
Issues Task Force  (EITF)  Issue 02-3,  "Accounting  for  Contracts  Involved in
Energy Trading and Risk Management Activities" (EITF 02-3). EITF 02-3 was issued
by the EITF in June 2002 and  required  revenues  and  energy  costs  related to
energy trading contracts to be presented on a net basis in the income statement.
For  comparative  purposes,  energy  costs  related to energy  trading have been
reclassified  as  revenue  for  prior  periods  to  conform  to the net basis of
presentation required by EITF 02-3.

         The changes in  Generation's  revenue,  net of purchased power and fuel
expense,  for the three months ended March 31, 2003  compared to the same period
in 2002,  included the following:

o    increased demand due to customers returning to PECO from alternative energy
     suppliers  and favorable  weather  conditions in the ComEd and PECO service
     territories  in 2003  resulting  in net volume and price  increases  of $34
     million,

o    increases  of $32 million for  generation  from plants  acquired  after the
     first quarter of 2002 resulting in higher market sales,

o    increased  revenue to ComEd of $16 million  associated with the adoption of
     SFAS No. 143, which was not included in revenue in 2002,

o    mark-to-market losses on hedging activities of $31 million in 2003 compared
     to mark-to-market gains of $6 million on hedging activities in 2002, and

o    write-down  of  nuclear  fuel  of  $6  million  in  2003   resulting   from
     underperforming fuel at the Quad Cities Unit 1.

         The changes in operating  income,  other than changes in revenue net of
purchased  power and fuel  expense,  for the three  months  ended March 31, 2003
compared to the same period in 2002, included the following:

o    higher  costs of $27  million  for  employee  medical,  pension  and  other
     benefits in 2003, partially offset by a one-time executive severance charge
     of $19 million in 2002,

o    increased O&M costs of $19 million due to asset acquisitions made after the
     first quarter of 2002,

o    reduced  refueling  outage  costs  of  $32  million  resulting  from  fewer
     refueling outage days in 2003,

o    additional  depreciation of $15 million due to capital  additions placed in
     service and plant acquisitions made after the first quarter of 2002, and



                                       63



o    increased   accretion  expense  of  $57  million  primarily  due  to  asset
     retirement  obligation  accretion  due to the  adoption  of SFAS  No.  143,
     partially offset by reduced decommissioning expense of $33 million.

         The changes in income  before  income  taxes and  cumulative  effect of
changes in  accounting  principles  for the three  months  ended  March 31, 2003
compared to the same period in 2002, included the following:

o    a pre-tax impairment charge of $200 million related to Generation's  equity
     investment in Sithe,

o    increased decommissioning trust investment income of $20 million,

o    reduced equity in earnings of unconsolidated affiliates of $4 million, and

o    increased  interest expense of $2 million primarily due to the note payable
     to Sithe.

         Generation's  effective  income tax rate was 28.8% for the three months
ended  March  31,  2003  compared  to 40.5% for the same  period  in 2002.  This
decrease  was  primarily  attributable  to  the  impact  of  the  impairment  of
Generation's investment in Sithe and other tax benefits recorded in 2003.

         Cumulative effect of changes in accounting  principles  recorded in the
three months ended March 31, 2003 and 2002 included income of $108 million,  net
of income  taxes,  recorded in 2003  related to the adoption of SFAS No. 143 and
income of $13  million,  net of income  taxes,  recorded in 2002  related to the
adoption of SFAS No. 141,  "Business  Combinations"  (SFAS No. 141) and SFAS No.
142.  See  Note 2 of the  Condensed  Combined  Notes to  Consolidated  Financial
Statements for further discussion of these effects.

         Generation's  MWh deliveries  increased 12.6% in the three months ended
March 31, 2003 as compared to the same period in 2002. Increased deliveries were
a result of favorable weather conditions,  which increased the demand for Energy
Delivery  and higher  market sales  attributable  to the  increased  supply from
acquired generation and power uprates at existing facilities.

         The factors below  contributed to the overall reduction in Generation's
average margin for the three months ended March 31, 2003 as compared to the same
period in 2002.

         Generation's average revenue per MWh was affected by:

     o    increased  weighted  average on and off-peak prices per MWh for supply
          agreements with ComEd,

     o    higher prices per MWh on sales under supply  agreements with PECO, and

     o    higher market prices.

         Generation's supply mix changed due to:

     o    increased  nuclear  generation  due to a lower number of refueling and
          unplanned outages during 2003 compared to 2002,

     o    increased  fossil  generation due to the effect of the  acquisition of
          two  generating  plants in Texas in April  2002,  a  peaking  facility
          placed in  service in July 2002 and the Sithe New  England  (currently
          known as Exelon New England) plants  acquired in November 2002,  which
          in total account for an increase of 2,500 GWhs, and

     o    increased  quantity  of  purchased  power at higher  prices to service
          greater than anticipated customer loads.


                                       65






         Higher nuclear capacity factors and decreased nuclear  production costs
are primarily due to 30 fewer planned refueling outage days,  resulting in a $32
million  decrease in outage  costs,  in the three months ended March 31, 2003 as
compared to the same period in 2002. Additionally,  the three months ended March
31, 2003 included three  unplanned  outages  compared to five unplanned  outages
during the three months ended March 31, 2002.

- ---------------------------------------------------------------------------------------------------------


         The  changes  in  Enterprises'  operating  income  (loss) for the three
months  ended March 31, 2003  compared to the same period in 2002,  included the
following:

o    lower revenues of $14 million from Exelon Services as a result of reduced
     construction projects offset by lower construction costs of $13 million,

o    higher gross margins at InfraSource Inc. of $2 million primarily resulting
     from bad debt expense recorded in 2002 as a result of the downturn in the
     telecommunications industry,

o    lower gross margins at Exelon Energy of $12 million resulting from the
     reversal of mark-to-market adjustments of $7 million and additional gas
     supply costs of $11 million attributable to purchases at spot rates for gas
     in the Northeast, offset by higher gross margins of $6 million in the
     Midwest attributable to increased unit margins and higher volumes due to
     colder weather,

o    reductions in general and administrative expenses of $10 million primarily
     resulting from Exelon's 2002 Cost Management Initiative, and

o    accelerated depreciation of assets in 2002 relating to Exelon Energy's
     discontinuance of retail sales in the PJM region of $7 million.

         The changes in income (loss) before income taxes and cumulative  effect
of changes in  accounting principles for the three  months  ended March 31, 2003
compared to the same period in 2002, included the following:

o    lower interest expense of $2 million,

o    higher  equity in  earnings  of  unconsolidated  affiliates  of $4  million
     resulting  from  the  discontinuance  of  losses  from  the  AT&T  Wireless
     investment  as a result of its sale in the second  quarter of 2002,  and $3
     million resulting from lower costs at a communications joint venture, and

o    impairment of a software-related investment of $5 million due to an other
     than temporary decline in value. In the first quarter of 2002, Enterprises
     had a $2 million net realized loss on a communications investment and a $2
     million impairment of a communications investment.

                                       66




         The  effective  income  tax rate was 43.3% for the three  months  ended
March 31, 2003,  compared to 40.4% for the same period in 2002. This increase in
the  effective  tax rate was  attributable  to various  income tax related items
totaling $1 million.

         The cumulative effect of a change in accounting  principles recorded in
the three  months  ended  March 31,  2003 due to the  adoption  of SFAS No.  143
reduced net income by $1 million,  net of income taxes. The cumulative effect of
a change in  accounting  principle  recorded in the three months ended March 31,
2002 due to the adoption of SFAS No. 142 reduced net income by $243 million, net
of income  taxes (see Note 2 of the  Condensed  Combined  Notes to  Consolidated
Financial Statements).

         Enterprises  continues to pursue the divestiture of certain businesses;
however, it may be unable to successfully  implement its divestiture strategy of
certain  businesses  for a number of reasons,  including  an inability to locate
appropriate  buyers or to negotiate  acceptable terms for the  transactions.  In
addition,  the amount that Enterprises may realize from a divestiture is subject
to fluctuating  market conditions that may contribute to pricing and other terms
that are  materially  different  than expected and could result in a loss on the
sale. Timing of any divestitures may positively or negatively affect the results
of  operations as Exelon  expects  certain  businesses  to be  profitable  going
forward.

General

         Due to revenue  needs in the states in which Exelon  operates,  various
state income tax and fee increases have been proposed or are being contemplated.
If these  changes are enacted,  they could  increase  Exelon's  state income tax
expense.  At this time,  however,  Exelon cannot predict whether  legislation or
regulation  will be  introduced,  the  form of any  legislation  or  regulation,
whether  any  such  legislation  or  regulation  will  be  passed  by the  state
legislatures or regulatory bodies, and, if enacted, whether any such legislation
or regulation would be effective  retroactively or  prospectively.  As a result,
Exelon cannot  currently  estimate the effect of these potential  changes in tax
laws or regulation.

LIQUIDITY AND CAPITAL RESOURCES

         Exelon's  businesses  are capital  intensive  and require  considerable
capital resources.  These capital resources are primarily provided by internally
generated  cash flows from Energy  Delivery and  Generation's  operations.  When
necessary, Exelon obtains funds from external sources in the capital markets and
through bank  borrowings.  Exelon's  access to external  financing at reasonable
terms  depends on  Exelon's  and its  subsidiaries'  credit  ratings and general
business  conditions,  as well as that of the utility  industry  in general.  If
these  conditions  deteriorate  to where Exelon no longer has access to external
financing  sources at  reasonable  terms,  Exelon  has access to a $1.5  billion
revolving  credit  facility  that  Exelon  currently  utilizes


                                       67



to support its commercial paper program. See the Credit Issues section of
Liquidity and Capital Resources for further discussion. Exelon primarily uses
its capital resources to fund capital requirements, including construction, to
invest in new and existing ventures, to repay maturing debt and to pay common
stock dividends. Future acquisitions that Exelon may undertake may require
external financing, which might include Exelon issuing common stock.

Cash Flows from Operating Activities

         Cash flows  provided by operations for the three months ended March 31,
2003 were $383 million  compared to $826 million in the three months ended March
31,  2002.  The  decrease  in cash flows was  primarily  attributable  to a $305
million decrease in working capital. In the first quarter of 2003, approximately
40% of cash flows  provided by operations  were provided by Energy  Delivery and
60% were provided by Generation.  Enterprises'  cash flows from  operations were
immaterial  to  Exelon  for the  three  months  ended  March  31,  2003.  Energy
Delivery's cash flow from operating  activities  primarily results from sales of
electricity  and gas to a stable and diverse  base of retail  customers at fixed
prices.  Energy  Delivery's  future  cash flows will  depend upon the ability to
achieve cost savings in  operations  and the impact of the economy,  weather and
customer  choice  on  its  revenues.  Generation's  cash  flows  from  operating
activities  primarily  result  from the sale of  electric  energy  to  wholesale
customers,  including Energy Delivery and Enterprises.  Generation's future cash
flow from operating  activities will depend upon future demand and market prices
for  energy  and the  ability  to  continue  to  produce  and  supply  power  at
competitive  costs.  Although  the  amounts  may vary from period to period as a
result of the  uncertainties  inherent in business,  Exelon  expects that Energy
Delivery and Generation will continue to provide a reliable and steady source of
internal cash flow from operations for the foreseeable future.

Cash Flows from Investing Activities

         Cash flows used in  investing  activities  for the three  months  ended
March 31, 2003 were $457 million,  compared to $630 million for the three months
ended March 31, 2002.  The decrease is primarily  attributable  to a decrease in
capital expenditures due to two scheduled refueling outages occurring during the
three months ended March 31, 2003 compared to four outages in the same period in
the prior year and $70 million related to liquidated  damages from Raytheon (see
Note 8 of the Condensed  Combined Notes to Consolidated  Financial  Statements).
Capital  expenditures  by business  segment for the three months ended March 31,
2003 and 2002 were as follows:

         Energy   Delivery's   capital   expenditures   for  2003   reflect  the
continuation of efforts to


                                       68



further improve the reliability of its distribution system. Exelon anticipates
that Energy Delivery's capital expenditures will be funded by internally
generated funds, borrowings, the issuance of preferred securities, or capital
contributions from Exelon.

         Generation's  capital expenditures for 2003 reflect the construction of
three Exelon New England generating  facilities with projected capacity of 2,421
MWs of energy,  additions  to and  upgrades  of existing  facilities  (including
nuclear  refueling  outages), and nuclear  fuel.  In February  2002,  Generation
entered into an agreement to loan AmerGen up to $75 million at an interest  rate
of one-month  LIBOR plus 2.25%.  In July 2002,  the loan  agreement and the loan
were  increased to $100  million and the  maturity  date was extended to July 1,
2003. As of March 31, 2003,  the balance of the loan to AmerGen was $35 million.
Exelon  anticipates that  Generation's  capital  expenditures  will be funded by
internally generated funds, borrowings or capital contributions from Exelon.

         Enterprises'  capital expenditures for 2003 are primarily for additions
to or upgrades of existing facilities.  All of Enterprises' capital expenditures
are expected to be funded by capital contributions or borrowings from Exelon.

Cash Flows from Financing Activities

         Cash flows provided by financing  activities  were $108 million for the
three months  ended March 31, 2003  compared to $15 million for the three months
ended March 31, 2002. The increase is primarily  attributable  to an increase in
net  borrowings.  See  Notes  10 and  14 of  the  Condensed  Combined  Notes  to
Consolidated  Financial  Statements for further  discussion of Exelon's debt and
preferred securities financing activities in 2003.

Credit Issues

         Exelon meets its short-term  liquidity  requirements  primarily through
the issuance of commercial paper by the Exelon corporate holding company (Exelon
Corporate) and by ComEd,  PECO and Generation.  Exelon  Corporate  participates,
along with ComEd,  PECO and  Generation,  in a $1.5  billion  unsecured  364-day
revolving  credit  facility with a group of banks.  The credit  facility  became
effective on November  22, 2002 and  includes a term-out  option that allows any
outstanding borrowings at the end of the revolving credit period to be repaid on
November 21, 2004.  Exelon  Corporate  may increase or decrease the sublimits of
each of the participants upon written notification to the banks. As of March 31,
2003, Exelon  Corporate's  sublimit was $800 million,  ComEd's was $100 million,
PECO's was $600  million and there was no sublimit  for  Generation.  The credit
facility is used  principally to support the commercial paper programs of Exelon
Corporate,  ComEd, PECO and Generation. At March 31, 2003, Exelon's Consolidated
Balance Sheet reflected $1,150 million of commercial paper  outstanding of which
$250 million was classified as long-term  debt. For the three months ended March
31, 2003, the average interest rate on notes payable was approximately 1.41%.


                                       69



         The  credit  facility  requires  Exelon  Corporate,   ComEd,  PECO  and
Generation to maintain a cash from operations to interest  expense ratio for the
twelve-month  period  ended on the last day of any quarter.  The ratios  exclude
revenues and interest  expenses  attributable to  securitization  debt,  certain
changes  in  working   capital,   distributions   on  preferred   securities  of
subsidiaries and, in the case of Exelon Corporate and Generation,  revenues from
Exelon New England  and  interest  on the debt of Exelon New  England's  project
subsidiaries.  Exelon Corporate is measured at the Exelon consolidated level. At
March 31, 2003, Exelon Corporate,  ComEd, PECO and Generation were in compliance
with the  credit  agreement  thresholds.  The  following  table  summarizes  the
threshold  reflected in the credit  agreement that the ratio cannot be less than
for the twelve-month period ended March 31, 2003:




                                 Exelon Corporate             ComEd           PECO        Generation
- -------------------------------------------------------------------------------------------------------
                                                                             
Credit Agreement Threshold              2.65 to 1         2.25 to 1        2.25 to 1         3.25 to 1
- -------------------------------------------------------------------------------------------------------



         To  provide  an  additional   short-term  borrowing  option  that  will
generally  be more  favorable  to the  borrowing  participants  than the cost of
external financing, Exelon operates an intercompany money pool. Participation in
the money pool is subject to  authorization  by  Exelon's  corporate  treasurer.
ComEd and its subsidiary,  Commonwealth  Edison Company of Indiana,  Inc., PECO,
Generation and Exelon  Business  Services  Company (BSC) may  participate in the
money  pool  as  lenders  and  borrowers,  and  Exelon  Corporate  as a  lender.
Contributions  to and  permitted  borrowings  from the  money  pool are based on
whether the  contributions and borrowings result in economic benefits to all the
participants.  Interest on  borrowings  is based on  short-term  market rates of
interest,  or, if from an external source,  specific borrowing rates. During the
first quarter 2003,  ComEd had various loans to Generation under the money pool.
The maximum amount of loans  outstanding at any time during the quarter was $335
million. As of March 31, 2003, there was no outstanding balance on these loans.

         Exelon's access to the capital markets,  including the commercial paper
market,  and its  financing  costs in those  markets  depend  on the  securities
ratings of the entity that is accessing  the capital  markets.  None of Exelon's
borrowings is subject to default or  prepayment as a result of a downgrading  of
securities  ratings although such a downgrading could increase fees and interest
charges  under  Exelon's $1.5 billion  credit  facility and certain other credit
facilities.  From time to time,  Exelon  enters into energy  commodity and other
contracts that require the maintenance of investment  grade ratings.  Failure to
maintain  investment grade ratings would allow  counterparties to certain energy
commodity  contracts to terminate the contracts and settle the transactions on a
net present value basis.

         Exelon obtained an order from the United States Securities and Exchange
Commission  (SEC)  under PUHCA  authorizing  through  March 31,  2004  financing
transactions,  including  the issuance of common  stock,  preferred  securities,
long-term  debt and  short-term  debt,  in an aggregate  amount not to exceed $4
billion.  As of March 31, 2003,  there was $2.1  billion of financing  authority
remaining under the SEC order.  Exelon's request for an additional $4 billion in
financing  authorization  is pending  with the SEC.  The  current  order  limits
Exelon's  short-term  debt  outstanding  to $3 billion  of the $4 billion  total
financing  authority.  Exelon's  request  that  the  short-term  debt  sub-limit
restriction be eliminated is pending with the SEC. The SEC order also authorized
Exelon to issue guarantees of up to $4.5 billion outstanding at any one time. At


                                       70



March 31, 2003,  Exelon had provided  $1.5 billion of  guarantees  under the SEC
order. See Contractual Obligations, Commercial Commitments and Off-Balance Sheet
Obligations in this section for further discussion of guarantees.  The SEC order
requires  Exelon  and  ComEd to  maintain  a ratio  of  common  equity  to total
capitalization (including securitization debt) on and after June 30, 2002 of not
less than 30%. At March 31, 2003,  Exelon and ComEd's  common equity ratios were
32% and 46%,  respectively.  Exelon and ComEd  expect that they will  maintain a
common equity ratio of at least 30%.

         Under PUHCA, Exelon,  ComEd, PECO and Generation can pay dividends only
from retained, undistributed or current earnings. However, the SEC order granted
permission to ComEd, and to Exelon, to the extent Exelon receives dividends from
ComEd paid from ComEd additional  paid-in-capital,  to pay up to $500 million in
dividends  out of  additional  paid-in  capital,  although  Exelon  may  not pay
dividends out of paid-in capital after December 31, 2002 if its common equity is
less  than 30% of its  total  capitalization.  At March  31,  2003,  Exelon  had
retained  earnings of $2.3 billion,  including ComEd's retained earnings of $652
million, PECO's retained earnings of $447 million and Generation's undistributed
earnings of $980 million. Exelon is also limited by order of the SEC under PUHCA
to an aggregate  investment of $4 billion in exempt wholesale  generators (EWGs)
and foreign utility  companies  (FUCOs).  At March 31, 2003, Exelon had invested
$2.2 billion in EWGs,  leaving $1.8 billion of  investment  authority  under the
order.  Exelon's  request  for an  additional  $1.5  billion  in EWG  investment
authorization is pending with the SEC.

Contractual   Obligations,   Commercial   Commitments  and   Off-Balance   Sheet
Obligations

         Contractual  obligations represent cash obligations that are considered
to  be  firm  commitments  and  commercial   commitments  represent  commitments
triggered by future  events.  Exelon's  contractual  obligations  and commercial
commitments  as of March 31,  2003 were  materially  unchanged,  other  than the
normal  course of  business,  from the  amounts  set forth in the 2002 Form 10-K
except for the following:

     o    On March  3,  2003,  ComEd  entered  into an  agreement  with  various
          Illinois  electric  retail market  suppliers,  key customer groups and
          governmental parties regarding several matters affecting ComEd's rates
          for electric service (Agreement). The Agreement addressed, among other
          things,  issues related to ComEd's residential  delivery services rate
          proceeding, market value index proceeding, the process for competitive
          service  declarations for large-load customers and an extension of the
          purchased power agreement  (PPA) with  Generation.  The parties to the
          Agreement  agreed to make and support a series of coordinated  filings
          intended to lead to the issuance by the Illinois  Commerce  Commission
          (ICC) of orders  consistent  with the Agreement.  Those orders,  which
          were issued on March 28,  2003,  are subject to  rehearing.  Rehearing
          requests  have been  filed  with the ICC.  Rehearing  requests  may be
          considered  through  the middle of May 2003.  The  Agreement  will not
          become  effective  as  long  as the  ICC  orders  are  subject  to any
          rehearing  request or if a stay is issued with respect to any of those
          orders.

              The Agreement  provides for a modification of the methodology used
          to determine  ComEd's market value energy credit.  That credit is used
          to determine the price for specified  market-based  rate offerings and
          the amount of the CTC that ComEd is allowed


                                       71


          to collect  from  customers  who select an ARES or the PPO. The credit
          will be adjusted  upward through agreed upon "adders," which will take
          effect in June 2003 and will have the effect of  reducing  ComEd's CTC
          charges to  customers.  The  estimated  annual  revenue  impact of the
          reduction in CTC revenues  under the  Agreement is  approximately  $65
          million to $70  million.  In  addition,  customers  will be offered an
          option to lock in CTC charges  for longer  periods.  Currently,  those
          charges are subject to change annually.

              During first quarter of 2003,  ComEd recorded a charge to earnings
          associated  with the funding of  specified  programs  and  initiatives
          associated  with the Agreement of $51 million on a present value basis
          before income taxes.  This amount is partially  offset by the reversal
          of a $12 million  (before  income taxes)  reserve  established  in the
          third quarter of 2002 for a potential capital  disallowance in ComEd's
          delivery services rate proceeding and a credit of $10 million (before
          income  taxes)  related to the  capitalization  of employee  incentive
          payments provided for in the delivery services order. The net one-time
          charge for these items is $29 million (before income taxes).

     o    ComEd  and  PECO  have  entered  into  several  agreements  with a tax
          consultant  related to the filing of refund  claims with the  Internal
          Revenue  Service (IRS).  The fees for these  agreements are contingent
          upon a  successful  outcome  and are based  upon a  percentage  of the
          refunds  recovered from the IRS, if any. As such, ComEd and PECO would
          have positive net cash flows  related to these  agreements if any fees
          are paid to the tax  consultant.  These  potential  tax  benefits  and
          associated fees could be material to the financial  position,  results
          of  operations  and cash  flows of Energy  Delivery.  Energy  Delivery
          cannot  predict  the timing of the final  resolution  of these  refund
          claims.

     o    See Notes 10 and 14 to the Condensed  Combined  Notes to  Consolidated
          Financial  Statements for  discussion of material  changes in Exelon's
          debt and preferred securities  obligations from those set forth in the
          2002 Form 10-K.

     o    See Note 8 of the Condensed  Combined Notes to Consolidated  Financial
          Statements for commercial  commitments  tables  representing  Exelon's
          commitments   not  recorded  on  the  balance  sheet  but  potentially
          triggered by future events,  including  obligations to make payment on
          behalf of other  parties and  financing  arrangements  to secure their
          obligations.

         The changes in electric  retail  revenues  for the three  months  ended
March 31, 2003, as compared to the same period in 2002, are  attributable to the
following:

                                               Variance
- --------------------------------------------------------
Rate Changes                               $       82

- --------------------------------------------------------

     o    Rate Changes.  The increase in revenues  attributable  to rate changes
          reflects the  collection of additional  CTC's in 2003 by ComEd of $105
          million  due to an  increase  in the number of  customers  choosing an
          alternative  energy supplier and changes in the wholesale market price
          of  electricity,   net  of  increased  mitigation  factors.  Increased
          wholesale market prices  decreased  revenue received under ComEd's PPO
          by $23 million.


                                       75



     o    Weather. The demand for electricity is impacted by weather conditions.
          Very warm  weather  in summer  months  and very cold  weather in other
          months is referred to as "favorable weather conditions," because these
          weather   conditions   result  in  increased   sales  of  electricity.
          Conversely,  mild weather reduces  demand.  The weather impact for the
          three months ended March 31, 2003 was  favorable  compared to the same
          period in 2002 as a result of colder winter  weather in 2003.  Heating
          degree-days  increased  17% in the three  months  ended March 31, 2003
          compared to the same period in 2002.

     o    Customer  Choice.  All ComEd  customers  have the  choice to  purchase
          energy from other suppliers. This choice generally does not impact the
          volume of  deliveries,  but affects  revenue  collected from customers
          related to energy supplied by ComEd. However, as of March 31, 2003, no
          alternative electric supplier has sought approval from the ICC, and no
          electric  utilities have chosen to enter the ComEd residential  market
          for the supply of electricity.

              The decrease in revenues  reflects  customers in Illinois electing
          to  purchase  energy  from an ARES or the PPO.  As of March 31,  2003,
          approximately  22,700 retail  customers had elected to purchase energy
          from an  ARES  or the  ComEd  PPO.  This  represents  an  increase  in
          delivered MWhs to such customers  from  approximately  4.8 million for
          the three  months  ended  March 31,  2002 to 6.2 million for the three
          months  ended March 31,  2003,  or from 24% to 29% of total  quarterly
          retail deliveries.

     o    Volume.  Revenues from higher delivery  volume,  exclusive of weather,
          increased due to an increased  number of customers and increased usage
          per customer, primarily small commercial and industrial.

         The $7 million increase in wholesale and miscellaneous  revenue for the
three  months  ended March 31, 2003 as compared to the three  months ended March
31,  2002 was due  primarily  to a $5  million  increase  in sales for resale to
municipalities  and others as a result of a 17% increase in heating  degree-days
in 2003.

Purchased Power
         Purchased  power  expense  increased  $40 million,  or 7% for the three
months  ended March 31,  2003.  The  increase  in  purchased  power  expense was
primarily  attributable  to a $20  million  increase  due to  favorable  weather
conditions,  an increase of $12 million due to higher volume, $17 million due to
pricing  changes  related to ComEd's PPA with  Generation and an increase of $16
million under the PPA related to decommissioning collections associated with the
adoption  of SFAS No. 143 that were not  included  in  purchased  power in 2002,
offset by a $28 million  decrease as a result of customers  choosing to purchase
energy from an ARES. The $16 million increase in purchased power expense related
to SFAS No. 143 is offset by lower regulatory asset amortization.

Operating and Maintenance
         Operating and maintenance (O&M) expense increased $24 million,  or 10%,
for the three  months  ended  March 31,  2003.  The  increase in O&M expense was
primarily  attributable  to a net one-time  charge of $41 million in 2003 as the
result of the Agreement as more fully  described in Note 4 - Regulatory  Issues,
offset by higher corporate allocations in 2002 due to executive severance.


                                       76



Depreciation and Amortization
         Depreciation and amortization  expense  decreased $41 million,  or 30%,
for the three months ended March 31, 2003 as follows:



                                                    Three Months Ended March 31,

- --------------------------------------------------------------------------------------------------
Total Depreciation and Amortization                  $      94         $     135        $     (41)          (30.4%)
==================================================================================================



         The  decrease  in  depreciation  expense  is  primarily  due  to  lower
depreciation rates effective July 1, 2002,  partially offset by higher property,
plant  and  equipment  balances.   ComEd  completed  a  depreciation  study  and
implemented   lower   depreciation   rates  effective  July  1,  2002.  The  new
depreciation rates reflect ComEd's  significant  construction  program in recent
years, changes in and development of new technologies,  and changes in estimated
plant service lives since the last  depreciation  study. The annual reduction in
depreciation expense is estimated to be approximately $100 million ($60 million,
net of income taxes) based on December 31, 2001 plant  balances.  As a result of
the change,  depreciation  expense  decreased $24 million ($14  million,  net of
income taxes) for the three months ended March 31, 2003.

         Recoverable transition costs amortization decreased in the three months
ended March 31, 2003  compared  to the same  period in 2002.  The  decrease is a
result of the extension of the rate freeze  through 2006 which  occurred in June
2002. ComEd expects to fully recover its recoverable transition costs regulatory
asset  balance of $164  million by 2006.  Consistent  with the  provision of the
Illinois legislation, regulatory assets may be recovered at amounts that provide
ComEd an earned return on common equity within the Illinois legislation earnings
threshold.

         The   decrease  in  other   amortization   primarily   relates  to  the
reclassification  of a regulatory asset for nuclear  decommissioning as a result
of the  adoption of SFAS No. 143 in 2003 (see Note 2 of the  Condensed  Combined
Notes  to  Consolidated  Financial  Statements).  This  decrease  is  offset  by
increased purchased power expense from Generation.

Taxes Other Than Income
         Taxes other than income  increased by $7 million or 10%, as a result of
a $4  million  increase  in real  estate and  municipal  taxes and $1 million in
Illinois Public Utility Fund taxes which were not charged in 2002.


                                       77



Interest Charges
         Interest  charges  consist of  interest  expense and  distributions  on
Company-Obligated  Mandatorily  Redeemable  Preferred  Securities  of Subsidiary
Trusts.  Interest  charges  decreased $16 million,  or 13%, for the three months
ended  March  31,  2003.   The  decrease  in  interest   expense  was  primarily
attributable  to the impact of lower  interest  rates for the three months ended
March 31, 2003 as compared to the three  months  ended March 31,  2002   and the
annual retirement of $340 million in Transitional Trust Notes.

Other, Net
         Other, Net increased  income by $8 million for the three  months  ended
March 31, 2003. The increase was primarily attributable to the reversal of a $12
million reserve in 2003 for a potential plant  disallowance as the result of the
Agreement as more fully  described in Note 4 to the Condensed  Combined Notes to
Consolidated Financial Statements.

Income Taxes
         The  effective  income  tax rate was 39.9% for the three  months  ended
March 31, 2003, compared to 39.4% for the three months ended March 31, 2002.

         Due to revenue  needs in the states in which  ComEd  operates,  various
state income tax and fee increases have been proposed or are being contemplated.
If these  changes are  enacted,  they could  increase  ComEd's  state income tax
expense.  At this time,  however,  ComEd cannot predict  whether  legislation or
regulation  will be  introduced,  the  form of any  legislation  or  regulation,
whether  any  such  legislation  or  regulation  will  be  passed  by the  state
legislatures or regulatory bodies, and, if enacted, whether any such legislation
or regulation would be effective  retroactively or  prospectively.  As a result,
ComEd cannot  currently  estimate the effect of these  potential  changes in tax
laws or regulation.

         Cumulative  Effect of a Change in  Accounting  Principle
         On January 1, 2003, ComEd adopted SFAS No. 143,  resulting in income of
$5 million.

LIQUIDITY AND CAPITAL RESOURCES

         ComEd's business is capital intensive and requires considerable capital
resources.  ComEd's  capital  resources  are  primarily  provided by  internally
generated  cash flows from  operations  and, to the extent  necessary,  external
financing  including the issuance of commercial  paper or  participation  in the
intercompany  money pool.  ComEd's  access to external  financing at  reasonable
terms is dependent on its credit  ratings and general  business  conditions,  as
well as that of the utility industry in general. If these conditions deteriorate
to where ComEd no longer has access to external  financing sources at reasonable
terms,  ComEd has access to a revolving  credit  facility  that ComEd  currently
utilizes to support its commercial paper program.  See the Credit Issues section
of Liquidity and Capital Resources for further discussion. Capital resources are
used primarily to fund ComEd's  capital  requirements,  including  construction,
repayments of maturing debt and the payment of dividends.


                                       78



Cash Flows from Operating Activities

         Cash flows provided by operations were $67 million for the three months
ended March 31, 2003  compared to $278  million for the three months ended March
31, 2002.  The decrease in cash flows in 2003 was  primarily  attributable  to a
$216  million  decrease  in  working  capital  as a  result  of the  paydown  of
intercompany  payables  to  affiliates  and  other  outstanding  liabilities,  a
decrease in depreciation  and  amortization of $41 million offset by an increase
in net income of $66  million.  ComEd's  future  cash flows will depend upon the
ability to achieve  cost  savings in  operations  and the impact of the economy,
weather, and customer choice on its revenues. Although the amounts may vary from
period to period as a result of  uncertainties  inherent in the business,  ComEd
expects to continue  to provide a reliable  and steady  source of internal  cash
flow from operations for the foreseeable future.

Cash Flows from Investing Activities

         Cash flows used in investing activities were $164 million for the three
months ended March 31, 2003  compared to $175 million for the three months ended
March 31, 2002. The decrease in cash flows used in investing  activities in 2003
was primarily attributable to an $8 million decrease in capital expenditures.

         ComEd estimates that it will spend  approximately $720 million in total
capital  expenditures  for 2003.  Approximately  two-thirds of the budgeted 2003
expenditures  are for continuing  efforts to further  improve the reliability of
its  transmission  and  distribution  systems.  The  remaining  one third is for
capital additions to support new business and customer growth. ComEd anticipates
that its capital  expenditures  will be funded by  internally  generated  funds,
borrowings,  the issuance of preferred securities, or capital contributions from
Exelon.  ComEd's proposed capital expenditures and other investments are subject
to periodic  review and revision to reflect  changes in economic  conditions and
other factors.

Cash Flows from Financing Activities

         Cash flows from  financing  activities  were $113 million for the three
months  ended March 31, 2003 as compared to cash flows used in  financing of $44
million for the three  months ended March 31,  2002.  Cash flows from  financing
activities  were primarily  attributable  to debt issuance  partially  offset by
retirements and redemptions and payments of dividends to Exelon. The increase in
cash flows from financing activities is primarily attributable to increased debt
and preferred securities issuances of $500 million partially offset by increased
debt and preferred securities redemptions of $306 million and increased interest
rate  swap  settlement  payments  of $34  million.  See  Notes  10 and 14 of the
Condensed  Combined  Notes to  Consolidated  Financial  Statements  for  further
discussion of ComEd's debt and preferred securities financing activities.  ComEd
paid a $120 million  dividend to Exelon  during the three months ended March 31,
2003  compared to a $118  million  dividend for the three months ended March 31,
2002.


                                       79



         Credit Issues

         ComEd meets its short-term liquidity requirements primarily through the
issuance of commercial  paper and borrowings  from Exelon's  intercompany  money
pool.  ComEd,  along with Exelon,  PECO, and Generation,  participates in a $1.5
billion  unsecured  364-day revolving credit facility with a group of banks. The
credit  facility that became  effective on November 22, 2002 includes a term-out
option that allows any outstanding borrowings at the end of the revolving credit
period to be repaid on November  21,  2004.  Exelon may increase or decrease the
sublimits of each of the participants upon written notification to the banks. As
of March 31, 2003,  ComEd's  sublimit was $100 million.  The credit  facility is
used principally to support ComEd's commercial paper program. At March 31, 2003,
ComEd's  Consolidated  Balance Sheet  reflects $45 million in  commercial  paper
outstanding.  For the three months ended March 31,  2003,  the average  interest
rate on notes payable was approximately 1.48%.

         The credit  facility  requires ComEd to maintain a cash from operations
to interest expense ratio for the  twelve-month  period ended on the last day of
any quarter.  The ratio excludes revenues and interest expenses  attributable to
securitization  debt,  certain changes in working capital,  and distributions on
preferred securities of subsidiaries.  ComEd's threshold for the ratio reflected
in the  credit  agreement  cannot be less  than  2.25 to 1 for the  twelve-month
period ended March 31, 2003. At March 31, 2003, ComEd was in compliance with the
credit agreement thresholds.

         To  provide  an  additional   short-term  borrowing  option  that  will
generally  be more  favorable  to the  borrowing  participants  than the cost of
external financing, Exelon operates an intercompany money pool. Participation in
the money pool is subject to authorization  by the Exelon  corporate  treasurer.
ComEd and its subsidiary  Commonwealth Edison of Indiana, Inc., PECO, Generation
and BSC may  participate in the money pool as lenders and borrowers,  and Exelon
as a lender.  Funding of, and borrowings  from, the money pool are predicated on
whether  such  funding  results  in  mutual  economic  benefits  to  each of the
participants,  although  Exelon is not  permitted to be a net borrower  from the
money pool.  Interest  on  borrowings  is based on  short-term  market  rates of
interest  or  specific  borrowing  rates if the funds are  provided  by external
financing.  There were no material money pool  transactions in 2002.  During the
first quarter 2003,  ComEd had various loans to Generation under the money pool.
The maximum amount of outstanding  loans at any time during the quarter was $335
million. As of March 31, 2003, there was no outstanding balance on these loans.

         ComEd's access to the capital  markets,  including the commercial paper
market, and its financing costs in those markets are dependent on its securities
ratings.  None of ComEd's  borrowings  is subject to default or  prepayment as a
result of a downgrading of securities  ratings although such a downgrading could
increase interest charges under certain bank credit facilities.

         Under  PUHCA,  ComEd can only pay  dividends  from  retained or current
earnings.  However,  the SEC has  authorized  ComEd to pay up to $500 million in
dividends  out of  additional  paid-in  capital,  provided  ComEd  may  not  pay
dividends out of paid-in capital after December 31, 2002 if its common equity is
less than 30% of its total capitalization  (including


                                       80


transitional  trust notes).  At March 31, 2003,  ComEd had retained  earnings of
$652 million and its common equity ratio was 46%.

Long-term debt included $1.9 billion of transitional trust notes.

Contractual   Obligations,   Commercial   Commitments  and   Off-Balance   Sheet
Obligations

         Contractual  obligations represent cash obligations that are considered
to  be  firm  commitments  and  commercial   commitments  represent  commitments
triggered by future  events.  ComEd's  contractual  obligations  and  commercial
commitments as of March 31, 2003 were  materially  unchanged,  other than in the
normal  course of  business,  from the  amounts  set forth in the 2002 Form 10-K
except for the following:

     o    On March 3,  2003,  ComEd  entered  into the  Agreement  with  various
          Illinois  electric  retail market  suppliers,  key customer groups and
          governmental parties regarding several matters affecting ComEd's rates
          for electric  service.  The Agreement  addressed,  among other things,
          issues  related  to  ComEd's   residential   delivery   services  rate
          proceeding, market value index proceeding, the process for competitive
          service  declarations for large-load customers and an extension of the
          PPA with  Generation.  The parties to the Agreement agreed to make and
          support  a  series  of  coordinated  filings  intended  to lead to the
          issuance by the ICC of orders  consistent  with the  Agreement.  Those
          orders, which were issued on March 28, 2003, are subject to rehearing.
          Rehearing  requests have been filed with the ICC.  Rehearing  requests
          may be considered  through the middle of May 2003.  The Agreement will
          not become  effective  as long as the ICC  orders  are  subject to any
          rehearing  request or if a stay is issued with respect to any of those
          orders.

              The Agreement  provides for a modification of the methodology used
     to determine  ComEd's  market value energy  credit.  That credit is used to
     determine  the price for  specified  market-based  rate  offerings  and the
     amount of the CTC that  ComEd is  allowed to  collect  from  customers  who
     select an ARES or the PPO.  The  credit  will be  adjusted  upward  through
     agreed  upon "adders,"  which will take effect in June 2003, and would have
     the effect of  reducing  ComEd's CTC charges to  customers.  The  estimated
     annual  revenue impact of the reduction in CTC revenues under the Agreement
     would be approximately $65 million to $70 million.  In addition,  customers
     will be  offered  an  option to lock in CTC  charges  for  longer  periods.
     Currently, those charges are subject to change annually.

              In the first quarter of 2003,  ComEd recorded a charge to earnings
     associated   with  the  funding  of  specified   programs  and  initiatives
     associated  with the  Agreement  of $51  million on a present  value  basis
     before income taxes.  This amount is partially  offset by the reversal of a
     $12 million (before income taxes) reserve  established in the third quarter
     of 2002 for a potential  capital  disallowance in ComEd's delivery services
     rate proceeding   and a credit of $10 million (before income taxes) related
     to the  capitalization of employee  incentive  payments provided for in the
     delivery  services  order.  The net one-time  charge for these items is $29
     million (before income taxes).

     o    ComEd  has  entered  into  several  agreements  with a tax  consultant
          related  to the  filing of refund  claims  with the IRS.  The fees for
          these  agreements  are  contingent  upon a successful  outcome and are
          based upon a percentage of the refunds recovered from the IRS, if any.
          As


                                       81



         such,  ComEd  would  have  positive  net cash  flows  related  to these
         agreements if any fees are paid to the tax consultant.  These potential
         tax benefits  and  associated  fees could be material to the  financial
         position,  results of operations and cash flows of ComEd.  ComEd cannot
         predict the timing of the final resolution of these refund claims.

     o    See Notes 10 and 14 to the Condensed  Combined  Notes to  Consolidated
          Financial  Statements  for  discussion of material  changes in ComEd's
          debt and preferred securities  obligations from those set forth in the
          2002 Form 10-K.

     o    See Note 8 of the Condensed  Combined Notes to Consolidated  Financial
          Statements  for commercial  commitments  tables  representing  ComEd's
          commitments   not  recorded  on  the  balance  sheet  but  potentially
          triggered by future events,  including  obligations to make payment on
          behalf of other  parties and  financing  arrangements  to secure their
          obligations.

Net Income
         Net income on common stock increased $48 million,  or 55% for the three
months ended March 31, 2003 as compared to the same period in 2002. The increase
was a result  of  higher  sales  volume  and  lower  interest  expense  on debt,
partially  offset by increased  income taxes and  depreciation  and amortization
expense.

Operating Revenue
         PECO's electric sales statistics are as follows:

     o    Weather.  The weather impact was favorable  compared to the prior year
          as a result of colder winter weather.  Heating  degree-days  increased
          33% for the three  months  ended March 31,  2003  compared to the same
          period in 2002.

     o    Volume.  Exclusive of weather impacts, higher delivery volume affected
          PECO's  revenue by $43  million  compared  to the same  period in 2002
          primarily related to increases in the residential and large commercial
          and industrial customer classes.

     o    Customer Choice. All PECO customers may choose to purchase energy from
          other suppliers. This choice generally does not impact kWh deliveries,
          but reduces  revenue  collected  from  customers  because they are not
          obtaining generation supply from PECO.

         As of March 31, 2003, the customer load served by alternative suppliers
was 1,062 MWs or 13.1% as compared  to 1,010 MWs or 13.1% as of March 31,  2002.
For the three months  ended March 31,  2003,  the percent of PECO's total retail
deliveries for which PECO was the electric  supplier was 92.8% compared to 88.2%
in 2002. As of March 31, 2003, the


                                       85



number of  customers  served by  alternative  suppliers  was 273,724 or 17.9% as
compared to 357,789 or 23.4% as of March 31,  2002.  The  increases in customers
and the  percentage of load served by PECO  primarily  resulted  from  customers
selecting or returning to PECO as their electric generation supplier.

         The PUC's Final Electric Restructuring Order established MST to promote
competition.  The MST requirements  provide that if, as of January 1, 2003, less
than 50% of  residential  and  commercial  customers  have chosen an alternative
electric generation supplier, the number of customers sufficient to meet the MST
shall be randomly  selected and assigned to an alternative  electric  generation
supplier  through a PUC  determined  process.  On January 1, 2003, the number of
customers choosing an alternative  electric generation supplier did not meet the
MST.  In January  2003,  PECO  submitted  to the PUC an MST plan to meet the 50%
threshold  requirement for its commercial  customers,  which was approved by the
PUC in February  2003. As of March 31, 2003,  an auction had been  completed for
the  commercial  customers  and the  customer  enrollment  phase is currently in
process.  The randomly selected customers will be transferred to the alternative
electric  generation  suppliers in May 2003, if they do not choose the option to
not  participate  in the program.  In February  2003,  PECO filed a  residential
customer MST plan,  and on May 1, 2003,  the PUC approved the plan. The approved
plan provides for a two-step  process with a total of up to 400,000  residential
customers being assigned to winning  alternative  electric  generation  supplier
bidders:  up to 100,000 in July 2003, and another  300,000 in December 2003. Any
customer  transferred  would have the right to return to PECO at any time.  PECO
does not expect the  transfer  of  customers  pursuant to the MST plan to have a
material impact on its results of operations, financial position or cash flows.


o    Other  Effects.  The  increase in  revenues  attributable  to rate  changes
     primarily  reflects an  increase  in the  average  price mix related to the
     large  commercial  and  industrial  customer  class as compared to the same
     period in 2002.

         The changes in gas revenue for the three  months  ended March 31, 2003,
as compared to the same period in 2002, are as follows:

                                                                          Variance

========================================================================================




     o    Weather.  The weather impact was favorable  compared to the prior year
          as a result of colder winter weather.  Heating  degree-days  increased
          33% in the three  months  ended  March 31,  2003  compared to the same
          period in 2002.

     o    Volume. Exclusive of weather impacts, higher delivery volume increased
          revenue in the three months ended March 31, 2003  compared to the same
          period  in  2002  resulting  from  customer   growth.   Deliveries  to
          customers, excluding the effects of weather, increased 5% in the three
          months ended March 31, 2003 compared to the same period in 2002.

     o    Rate Changes. The favorable variance in rates is attributable to a 15%
          increase in the purchased gas adjustment by the PUC effective March 1,
          2003.  The average  rate per million  cubic feet for the three  months
          ended March 31, 2003 was 9% higher than the same 2002  period.  PECO's
          gas rates  are  subject  to  periodic  adjustments  by the PUC and are
          designed to recover from or refund to customers the difference between
          actual cost of purchased gas and the amount included in base rates and
          to recover or refund increases or decreases in certain state taxes not
          recovered in base rates.

Purchased Power
         Purchased  power  expense  for the three  months  ended  March 31, 2003
increased  $71 million as compared to the same period in 2002.  The  increase in
purchased power expense was primarily attributable to $22 million as a result of
favorable  weather  conditions,  $17  million  related to higher  PJM  ancillary
charges,  $16 million from customers in  Pennsylvania  selecting or returning to
PECO as their  electric  generation  supplier  and $16 million  attributable  to
higher electric delivery volume.

Fuel
         Fuel expense for the three months  ended March 31, 2003  increased  $56
million as compared  to the same period in 2002.  This  increase  was  primarily
attributable  to $40 million as a result of  favorable  weather  conditions,  $8
million  attributable to higher delivery  volumes and $3 million from higher gas
prices.


                                       87



Operating and Maintenance
         O&M expense for the three  months  ended  March 31, 2003  increased  $3
million,  or 2%, as  compared to the same  period in 2002.  The  increase in O&M
expense was primarily  attributable to $4 million of incremental  storm costs in
2003,  $4  million  of  additional  employee  benefits  costs and $8  million of
additional  miscellaneous  other net  positive  impacts  partially  offset by $7
million  related to lower  corporate  allocations  and $6 million of lower costs
associated with the deployment of automated meter reading technology.

Depreciation and Amortization
         Depreciation and amortization  expense for the three months ended March
31, 2003 increased $8 million,  or 7%, as compared to the same period in 2002 as
follows:



                                                    Three Months Ended March 31,

====================================================================================================


           The additional  amortization  of the CTC is in accordance with PECO's
original  settlement under the Pennsylvania  Competition Act and the increase in
depreciation expense resulted from additional plant in service.

Taxes Other Than Income
         Taxes  other than  income for the three  months  ended  March 31,  2003
increased  $4  million,  or 7%, as  compared  to the same  period  in 2002.  The
increase was primarily  attributable to $7 million of additional  gross receipts
tax related to additional revenues, partially offset by a $2 million decrease in
real estate taxes.

Interest Charges
         Interest  charges  consist of  interest  expense and  distributions  on
Company-Obligated  Mandatorily  Redeemable Preferred Securities of a Partnership
(COMRPS).  Interest  charges  decreased $9 million,  or 10%, in the three months
ended March 31, 2003 as compared to the same period in 2002.  The  decrease  was
primarily attributable to lower interest expense on long-term debt of $9 million
as a result of scheduled  principal payments and refinancing of existing debt at
lower interest rates.

Other, Net
         Other,  Net  increased  income by $8 million in the three  months ended
March 31, 2003 as compared  to the same  period in 2002.  The  increase in other
income was primarily  attributable  to higher  interest income of $5 million and
the favorable settlement of a customer contract of $3 million.


                                       88



Income Taxes
         The  effective  tax rate was 32.5% for the three months ended March 31,
2003 as compared to 32.1% for the same period in 2002.

         Due to  revenue  needs in the states in which  PECO  operates,  various
state income tax and fee increases have been proposed or are being contemplated.
If these  changes are  enacted,  they could  increase  PECO's  state  income tax
expense.  At this time,  however,  PECO cannot  predict  whether  legislation or
regulation  will be  introduced,  the  form of any  legislation  or  regulation,
whether  any  such  legislation  or  regulation  will  be  passed  by the  state
legislatures or regulatory bodies, and, if enacted, whether any such legislation
or regulation would be effective  retroactively or  prospectively.  As a result,
PECO cannot currently estimate the effect of these potential changes in tax laws
or regulation.

Preferred Stock Dividends
         Preferred  stock  dividends  for the three  months ended March 31, 2003
were consistent as compared to the same period in 2002.

LIQUIDITY AND CAPITAL RESOURCES

         PECO's business is capital intensive and requires  considerable capital
resources.  PECO's  capital  resources  are  primarily  provided  by  internally
generated  cash flows from  operations  and, to the extent  necessary,  external
financing  including the issuance of commercial  paper or  participation  in the
intercompany money pool. PECO's access to external financing at reasonable terms
is dependent on its credit ratings and general business  conditions,  as well as
that of the utility  industry in general.  If these  conditions  deteriorate  to
where PECO no longer  has access to  external  financing  sources at  reasonable
terms,  PECO has  access to a  revolving  credit  facility  that PECO  currently
utilizes to support its commercial paper program.  See the Credit Issues section
of Liquidity and Capital Resources for further discussion. Capital resources are
used  primarily to fund PECO's  capital  requirements,  including  construction,
repayments of maturing debt and payment of dividends.

Cash Flows from Operating Activities

         Cash flows  provided by operations for the three months ended March 31,
2003 and 2002 were $126 million and $100 million,  respectively. The increase in
cash flows was  primarily  attributable  to a $99  million  increase  in working
capital and a $48 million  increase  to net  income,  partially  offset by a $66
million  decrease in deferred taxes and a $62 million change in deferred  energy
costs. PECO's cash flow from operating  activities  primarily results from sales
of electricity and gas to a stable and diverse base of retail customers at fixed
prices.  PECO's  future  cash  flows  will  depend  upon the  ability to achieve
operating cost  reductions  and the impact of the economy,  weather and customer
choice on its revenues. Although the amounts may vary from period to period as a
result of the uncertainties inherent in its business,  PECO expects that it will
continue  to provide a reliable  and steady  source of  internal  cash flow from
operations for the foreseeable future.


                                       89



Cash Flows from Investing Activities

         Cash flows used in  investing  activities  for the three  months  ended
March 31, 2003 were $59  million,  compared to $65 million for the three  months
ended March 31, 2002.  The  decrease in cash flows used in investing  activities
was primarily attributable to a decrease in capital expenditures.

         PECO's  projected  capital  expenditures  for 2003  are  $270  million.
Approximately  one  half of the  budgeted  2003  expenditures  are  for  capital
additions to support  customer and load growth and the  remainder  for additions
and  upgrades  to  existing  facilities.   PECO  anticipates  that  its  capital
expenditures  will be funded by  internally  generated  funds,  borrowings,  the
issuance of preferred  securities,  or capital contributions from Exelon. PECO's
proposed  capital  expenditures  and other  investments  are subject to periodic
review and revision to reflect changes in economic conditions and other factors.

Cash Flows from Financing Activities

         Cash flows used in  financing  activities  for the three  months  ended
March 31,  2003 and 2002 were $26 million and $36  million,  respectively.  Cash
flows used in financing  activities are primarily  attributable  to debt service
and payment of dividends to Exelon. The decrease in cash flows used in financing
activities is primarily  attributable to additional  issuances of long-term debt
in the first  quarter of 2003 of $250  million,  partially  offset by additional
debt  service of $204  million.  See Notes 10 and 14 of the  Condensed  Combined
Notes to Consolidated Financial Statements for further discussion of PECO's debt
financing  activities.  For the three  months  ended March 31,  2003,  PECO paid
Exelon $89  million in common  stock  dividends  compared to $85 million for the
three months ended March 31, 2002.


                                       90



Credit Issues

         PECO meets its short-term liquidity  requirements primarily through the
issuance of commercial  paper and borrowings  from Exelon's  intercompany  money
pool.  PECO,  along with Exelon,  ComEd and  Generation,  participates in a $1.5
billion  unsecured  364-day revolving credit facility with a group of banks. The
credit  facility  became  effective  November  22, 2002 and  includes a term-out
option that allows any outstanding borrowings at the end of the revolving credit
period to be repaid on November  21,  2004.  Exelon may increase or decrease the
sublimits of each of the participants upon written notification to the banks. As
of March 31, 2003, PECO's sublimit was $600 million. The credit facility is used
by PECO principally to support its commercial paper program.  At March 31, 2003,
PECO's  Consolidated  Balance Sheet  reflects  $493 million in commercial  paper
outstanding,  of which $243  million is  classified  as notes  payable  and $250
million is  classified as long-term  debt.  For the three months ended March 31,
2003, the average interest rate on notes payable was approximately 1.33%.

         The credit facility requires PECO to maintain a cash from operations to
interest expense ratio for the twelve-month  period ended on the last day of any
quarter.  The ratio  excludes  revenues and interest  expenses  attributable  to
securitization  debt,  certain changes in working capital and  distributions  on
preferred  securities of subsidiaries.  PECO's threshold for the ratio reflected
in the  credit  agreement  cannot be less  than  2.25 to 1 for the  twelve-month
period ended March 31, 2003. At March 31, 2003,  PECO was in compliance with the
credit agreement thresholds.

         None of PECO's  borrowings  is subject to  default or  prepayment  as a
result of a downgrading of securities  ratings although such a downgrading could
increase interest charges under certain bank credit facilities.

         To  provide  an  additional   short-term  borrowing  option  that  will
generally  be more  favorable  to the  borrowing  participants  than the cost of
external financing, Exelon operates an intercompany money pool. Participation in
the money pool is subject to  authorization  by  Exelon's  corporate  treasurer.
ComEd and its subsidiary  Commonwealth Edison of Indiana, Inc., PECO, Generation
and BSC may  participate in the money pool as lenders and borrowers,  and Exelon
as a lender.  Funding of, and borrowings  from, the money pool are predicated on
whether  such  funding  results  in  mutual  economic  benefits  to  each of the
participants,  although  Exelon is not  permitted to be a net borrower  from the
money pool.  Interest  on  borrowings  is based on  short-term  market  rates of
interest,  or, if from an external source,  specific borrowing rates. There were
no material money pool transactions by PECO in the first quarter of 2003.

         Under  PUHCA,  PECO is precluded  from  lending or extending  credit or
indemnity  to  Exelon  and can pay  dividends  only  from  retained  or  current
earnings. At March 31, 2003, PECO had retained earnings of $447 million.

         Long-term debt included $4.1 billion of transition bonds.

Contractual   Obligations,   Commercial   Commitments  and   Off-Balance   Sheet
Obligations

         Contractual  obligations represent cash obligations that are considered
to  be  firm  commitments  and  commercial   commitments  represent  commitments
triggered  by future  events.  PECO's  contractual  obligations  and  commercial
commitments as of March 31, 2003 were  materially  unchanged,  other than in the
normal  course of  business,  from the  amounts  set forth in the 2002 Form 10-K
except for the following:

     o    PECO has entered into several agreements with a tax consultant related
          to the  filing  of  refund  claims  with the IRS.  The fees for  these
          agreements are contingent upon a successful outcome and are based upon
          a percentage of the refunds  recovered  from the IRS, if any. As such,
          PECO would have positive net cash flows related to these agreements if
          any fees are paid to the tax consultant.  These potential tax benefits
          and  associated  fees could be  material  to the  financial  position,
          results of operations and cash flows of PECO.  PECO cannot predict the
          timing of the final resolution of these refund claims.

     o    See Notes 10 and 14 of the Condensed  Combined  Notes to  Consolidated
          Financial  Statements  for further  discussion of material  changes in
          PECO's debt  obligations from those set forth in the 2002 Form 10-K.

     o    See Note 8 of the Condensed  Combined Notes to Consolidated  Financial
          Statements  for  commercial  commitments  tables  representing  PECO's
          commitments   not  recorded  on  the  balance  sheet  but  potentially
          triggered by future events,  including  obligations to make payment on
          behalf of other  parties and  financing  arrangements  to secure their
          obligations.

Net Income
         Generation's net income decreased by $23 million, or 29%, for the three
months ended March 31, 2003  compared to the same period in 2002.  Income (loss)
before cumulative effect of changes in accounting  principles  decreased by $118
million for the three months ended March 31, 2003 compared to the same period in
2002 primarily due to the after-tax  impairment  charge for Generation's  equity
investment  in Sithe of $130 million and higher  operating  expenses,  partially
offset by higher revenues and investment income.

Operating Revenues
         Revenues  increased by $418 million,  or 29% for the three months ended
March 31,  2003  compared  to the same period in 2002.  This  increase  resulted
primarily from a $295 million  increase in energy market sales,  due to regional
weather-related  demand.  Market sales also  increased $9 million for  increased
generation,  from the fossil  plants  acquired  after the first quarter of 2002,
related to gas  purchase  obligations.  In  addition,  sales to Energy  Delivery
increased by $85 million due to increased demand related to favorable weather in
ComEd and PECO's service  territories  during the first quarter of 2003 compared
to 2002,  and customers  returning to PECO from  alternative  energy  suppliers.
Revenues  from Energy  Delivery for the first  quarter of 2003 also included $16
million from ComEd related to nuclear decommissioning cost recoveries associated
with the  adoption  of SFAS  No.  143 that  was not  included  in 2002.  Trading
activity reduced revenue by $2 million during the first quarter of 2003 compared
to the same period of 2002.

         For the three months ended March 31, 2003 and 2002,  Generation's sales
and the supply of these sales were as follows:

         Generation's  MWh deliveries  increased 12.6% in the three months ended
March 31, 2003 compared to the same period in 2002.  Increased deliveries were a
result of favorable  weather  conditions,  which increased the demand for Energy
Delivery, and higher  market sales  attributable  to the  increased  supply from
acquired generation and power uprates at existing facilities.

         The factors below  contributed to the overall reduction in Generation's
average margin for the three months ended March 31, 2003 as compared to the same
period in 2002.

         Generation's average revenue per MWh was affected by:

     o    increased  weighted  average on and off-peak prices per MWh for supply
          agreements with ComEd,

     o    higher prices per MWh on sales under supply agreements with PECO, and

     o    higher market prices.

         Generation's supply mix changed due to:

     o    increased  nuclear  generation  due to a lower number of refueling and
          unplanned outages during 2003 compared to 2002,

     o    increased  fossil  generation due to the effect of the  acquisition of
          two  generating  plants in Texas in April  2002,  a  peaking  facility
          placed in  service  in July 2003 and the  Exelon  New  England  plants
          acquired in November  2002,  which in total account for an increase of
          2,500 GWhs, and

     o    increased  quantity  of  purchased  power at higher  prices to service
          greater customer loads as compared to 2002.

         The higher nuclear  capacity  factor and decreased  nuclear  production
costs are primarily due to 30 fewer planned refueling outage days,  resulting in
a $32 million decrease in outage


                                       95



costs,  in the three  months ended March 31, 2003 as compared to the same period
in 2002.  Additionally,  the three  months ended March 31, 2003  included  three
unplanned  outages  compared to five  unplanned  outages during the three months
ended March 31, 2002.

Purchased Power
         Purchased  power  increased $222 million,  or 36%, for the three months
ended  March 31, 2003  compared  to the same period in 2002 due to $185  million
related to higher  market prices and increased  purchases.  Increased  purchases
were due to higher  market sales and increased  demand from ComEd and PECO.  The
increase in purchased  power also reflects a $31 million loss on  mark-to-market
hedging  activity  for the three  months  ended March 31, 2003  compared to a $6
million gain in the same period in 2002.

Fuel
         Fuel expense increased $155 million, or 74%, for the three months ended
March 31, 2003  compared to the same period in 2002.  This increase is primarily
due to the higher  generation to meet  increased  demand from ComEd and PECO and
higher market sales.  Fossil and other fuel expense increased $140 million, as a
result of operating the  generation  plants  acquired after the first quarter of
2002.  Increased  fossil fuel expense  includes $9 million  related to increased
market sales,  from the  generating  plants  acquired after the first quarter of
2002,  related to gas purchase  obligations.  Nuclear fuel expense increased $19
million,  reflecting higher nuclear  generation and $6 million due to additional
fuel  amortization  resulting from under performing fuel at the Quad Cities Unit
1, which will be  completely  replaced in May 2003.  The second  quarter of 2003
will include  approximately $13 million of additional fuel amortization  related
to Quad Cities Unit 1. These increases in fuel expense were partially  offset by
a $4 million loss on emissions allowance sales recorded in 2002.

Operating and Maintenance
         O&M expense  increased $55 million,  or 13%, for the three months ended
March 31, 2003 compared to the same period in 2002.  The increase in O&M expense
was  primarily  attributable  to $39  million  of  accretion  expense  which was
recorded as depreciation and amortization  expense prior to the adoption of SFAS
No. 143, $18 million of accretion  expense related to SFAS No. 143 to adjust the
earnings impact of the net of decommissioning  revenues,  investment income, the
accretion  of the asset  retirement  obligation  and  depreciation  of the Asset
Retirement Cost asset (ARC) to zero, $27 million of additional employee benefits
costs,  and $19 million of additional  expenses due to asset  acquisitions  made
after the first  quarter of 2002.  This  increase  was  partially  offset by $32
million  of lower  nuclear  refueling  outage  costs  and a  one-time  executive
severance expense recorded in 2002 of $19 million.  For a further  discussion of
SFAS  No.  143  see  Note 2 of the  Condensed  Combined  Notes  to  Consolidated
Financial Statements.

Depreciation and Amortization
         Depreciation and amortization  expense  decreased $18 million,  or 29%,
for the three months  ended March 31, 2003  compared to the same period in 2002.
The  decrease  was  primarily   attributable  to  a  $33  million  reduction  in
decommissioning expense as these costs are included in operating and maintenance
expense  after the adoption of SFAS No. 143,  partially  offset by $6 million of
additional depreciation expense on capital additions placed in service after the
first quarter of 2002, $9 million related to plant  acquisitions  made after the
first quarter of 2002, and $1 million of depreciation  for the ARC asset related
to SFAS No.  143.  For a further  discussion  of SFAS No.  143 see Note 2 of the
Condensed Combined Notes to Consolidated Financial Statements.

                                       96



Taxes Other Than Income
         Taxes other than  income  decreased  $1  million,  or 2%, for the three
months ended March 31, 2003 compared to the same period in 2002 primarily due to
a $4 million decrease in payroll taxes partially offset by a $3 million increase
in property taxes related to asset  acquisitions made after the first quarter of
2002.

Interest Expense
         Interest  expense  increased  $2 million,  or 12%, for the three months
ended March 31,  2003  compared to the same  period in 2002.  The  increase  was
primarily due to $3 million of additional  interest  expense on the $534 million
note payable issued to Sithe in November 2002.

Equity in Earnings of Unconsolidated Affiliates
         Equity in earnings of unconsolidated  affiliates  decreased $4 million,
or 17%, for the three months ended March 31, 2003 compared to the same period in
2002.  The  decrease  was due to a $6 million  decrease in  Generation's  equity
earnings  in Sithe,  primarily  due to  Sithe's  sale of Exelon  New  England to
Generation in November 2002. This decrease was partially  offset by a $2 million
increase in Generation's equity earnings of AmerGen.

Other, Net
         Other,  Net decreased $183 million for the three months ended March 31,
2003 compared to the same period in 2002. This decrease is primarily a result of
the $200 million impairment charge related to Generation's  equity investment in
Sithe due to an other than temporary decline in value. This charge was partially
offset by higher investment income related to the decommissioning trust funds.

Income Taxes
         The  effective  income  tax rate was 28.8% for the three  months  ended
March 31, 2003  compared to 40.5% for the same period in 2002.  The decrease was
primarily attributed to the impact of the impairment of Generation's  investment
in Sithe and other tax benefits recorded in 2003.

         Due to  revenue  needs  in the  states  in which  Generation  operates,
various  state  income tax and fee  increases  have been  proposed  or are being
contemplated.  If these changes are enacted,  they could  increase  Generation's
state income tax  expense.  At this time,  however,  Generation  cannot  predict
whether  legislation  or  regulation  will  be  introduced,   the  form  of  any
legislation or regulation,  whether any such  legislation or regulation  will be
passed by the state legislatures or regulatory bodies, and, if enacted,  whether
any  such  legislation  or  regulation  would  be  effective   retroactively  or
prospectively.  As a result,  Generation cannot currently estimate the effect of
potential changes in tax law or regulation.

Cumulative Effect of Changes in Accounting Principles
         On January 1, 2003,  Generation  adopted  SFAS No. 143  resulting  in a
benefit of $108 million, net of income taxes of $70 million.

         On January 1, 2002,  Generation  adopted  SFAS No. 141  resulting  in a
benefit of $13 million, net of income taxes of $9 million.

LIQUIDITY AND CAPITAL RESOURCES

         Generation's  business is capital  intensive and requires  considerable
capital  resources.  Generation's  capital  resources are primarily  provided by
internally  generated cash flows from operations  and, to the extent  necessary,
external financings including the issuance of commercial paper and borrowings or
capital contributions from Exelon.  Generation's access to external financing at
reasonable  terms is  dependent  on its  credit  ratings  and  general  business
conditions,  as well as  that of the  utility  industry  in  general.  If  these
conditions  deteriorate  to where  Generation  no longer has access to  external
financing  sources at  reasonable  terms,  Generation  has access to a revolving
credit  facility.  See the  Credit  Issues  section  of  Liquidity  and  Capital
Resources for further  discussion.  Capital resources are used primarily to fund
Generation's capital requirements,  including  construction,  investments in new
and existing ventures, repayments of maturing debt and the payment of dividends.
Any future  acquisitions  could  require  external  financing or  borrowings  or
capital contributions from Exelon.

Cash Flows from Operating Activities

         Cash flows  provided  by  operations  were $278  million  for the three
months  ended March 31,  2003,  compared to $509  million for the same period in
2002.  The  decrease  in cash  flows from  operating  activities  was  primarily
attributable  to a $184 million  decrease in working capital. Generation's  cash
flows from  operating  activities  primarily  result  from the sale of  electric
energy to wholesale customers,  including Generation's  affiliated companies, as
well as settlements arising from Generation's  trading activities.  Generation's
future cash flow from  operating  activities  will depend upon future demand and
market prices for energy and the ability to continue to produce and supply power
at competitive costs.

Cash Flows from Investing Activities

         Cash flows used in investing activities were $216 million for the three
months  ended March 31,  2003,  compared to $379  million for the same period in
2002.  The decrease in cash flows used in  investing  activities  was  primarily
attributable  to  a  decrease  in  capital  expenditures.  Capital  expenditures
decreased $70 million related to liquidated damages from Raytheon (see Note 8 of
the  Condensed  Combined  Notes  to  Consolidated  Financial  Statements).   The
liquidated   damages  were  partially  offset  by  a  $58  million  increase  in
expenditures  related to the plants  acquired  after the first  quarter of 2002.
Nuclear fuel  expenditures  decreased due to two refueling outages that occurred
during the three  months  ended March 31, 2003  compared to four  outages in the
same period in the prior year.  Generation's  proposed capital  expenditures and
other investments are subject to periodic review and revision to reflect changes
in economic conditions and other factors.

         Generation's  capital expenditures for 2003 reflect the construction of
three Exelon New England generating  facilities with projected capacity of 2,421
MWs of energy and  additions to

                                       98



and upgrades of existing  facilities  (including  nuclear refueling outages) and
nuclear fuel.  In February  2002,  Generation  entered into an agreement to loan
AmerGen up to $75 million at an interest rate of one-month  LIBOR plus 2.25%. In
July 2002,  the loan  agreement and the loan were  increased to $100 million and
the  maturity  date was  extended  to July 1, 2003.  As of March 31,  2003,  the
balance  of the  loan  to  AmerGen  was $35  million.  Exelon  anticipates  that
Generation's  capital expenditures will be funded by internally generated funds,
borrowings or capital contributions from Exelon.

Cash Flows from Financing Activities

         Cash flows used in financing  activities were $63 million for the three
months  ended  March 31,  2003,  compared to cash flows  provided  by  financing
activities of $1 million for the same period in 2002.  The increase in cash used
in financing was primarily due to a $56 million increase in restricted cash as a
result of liquidating damage proceeds received from Raytheon in 2003 (see Note 8
of the Condensed Combined Notes to Consolidated Financial Statements).

Credit Issues

         Generation  meets  its  short-term  liquidity   requirements  primarily
through  intercompany  borrowings from Exelon,  the issuance of commercial paper
and participation in the intercompany money pool. Generation, along with Exelon,
ComEd and PECO,  participates  in a $1.5  billion  unsecured  364-day  revolving
credit facility with a group of banks.  The credit facility became  effective on
November  22, 2002 and  includes a term-out  option that allows any  outstanding
borrowings  at the end of the  revolving  credit period to be repaid on November
21,  2004.  Exelon  may  increase  or  decrease  the  sublimits  of  each of the
participants  upon written  notification  to these banks.  As of March 31, 2003,
there was no sublimit for Generation. The credit facility is expected to be used
by Generation principally to support its commercial paper program.

         The  credit  facility  requires  Generation  to  maintain  a cash  from
operations to interest  expense ratio for the  twelve-month  period ended on the
last day of any quarter.  The ratio excludes certain changes in working capital,
revenues  from  Exelon  New  England  and  interest  on the debt of  Exelon  New
England's project subsidiaries.  Generation's  threshold for the ratio reflected
in the  credit  agreement  cannot be less  than  3.25 to 1 for the  twelve-month
period ended March 31, 2003.  At March 31, 2003,  Generation  was in  compliance
with the credit agreement thresholds.

         To  provide  an  additional   short-term  borrowing  option  that  will
generally  be more  favorable  to the  borrowing  participants  than the cost of
external financing, Exelon operates an intercompany money pool. Participation in
the money pool is subject to authorization  by the Exelon  corporate  treasurer.
ComEd and its subsidiary  Commonwealth Edison of Indiana, Inc., PECO, Generation
and Business  Services  Company may participate in the money pool as lenders and
borrowers,  and Exelon as a lender.  Funding of, and borrowings  from, the money
pool are predicated on whether such funding results in mutual economic  benefits
to  each of the  participants,  although  Exelon  is not  permitted  to be a net
borrower  from the money pool.  Interest on  borrowings  is based on  short-term
market rates of interest,  or specific borrowing rates if the funds are provided
by external  financing.  During the first quarter 2003,  Generation  had various


                                       99



borrowings  from  ComEd  under  the  money  pool.  The  maximum  amount of loans
outstanding  at any time during the quarter  was $335  million.  As of March 31,
2003, there were no outstanding loan balances.

         Generation's  access to the capital  markets and its financing costs in
those  markets are dependent on its  securities  ratings.  None of  Generation's
borrowings is subject to default or  prepayment as a result of a downgrading  of
securities  ratings although such a downgrading  could increase interest charges
under certain bank credit  facilities.  From time to time Generation enters into
energy commodity and other derivative  transactions that require the maintenance
of investment grade ratings.  Failure to maintain investment grade ratings would
allow the counterparty to terminate the derivative and settle the transaction on
a net present value basis.

          Under PUHCA,  Generation can only pay dividends from  undistributed or
current  earnings.  Generation is precluded from lending or extending  credit or
indemnity to Exelon. At March 31, 2003, Generation had undistributed earnings of
$980 million.

Contractual   Obligations,   Commercial   Commitments  and   Off-Balance   Sheet
Obligations

         Contractual  obligations represent cash obligations that are considered
to  be  firm  commitments  and  commercial   commitments  represent  commitments
triggered by future events.  Generation's contractual obligations and commercial
commitments as of March 31, 2003 were materially  unchanged from the amounts set
forth in the 2002 Form 10-K except for the following:

o        See Note 8 of the Condensed  Combined Notes to  Consolidated  Financial
         Statements for commercial commitments tables representing  Generation's
         commitments not recorded on the balance sheet but potentially triggered
         by future  events,  including  obligations to make payment on behalf of
         other parties and financing arrangements to secure their obligations.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Commodity Price Risk
Generation
         Commodity   price  risk  is  associated  with  market  price  movements
resulting from excess or insufficient generation,  changes in fuel costs, market
liquidity  and other  factors.  Trading  activities  and  non-trading  marketing
activities  include the  purchase  and sale of electric  capacity and energy and
fossil fuels, including oil, gas, coal and emission allowances. The availability
and prices of energy and energy-related  commodities are subject to fluctuations
due to factors such as weather,  governmental environmental policies, changes in
supply and demand, state and Federal regulatory policies and other events.


                                      100



Normal Operations and Hedging Activities

         Electricity  available from Generation's owned or contracted generation
supply in excess of its obligations to customers,  including  Energy  Delivery's
retail load, is sold into the wholesale markets.  To reduce price risk caused by
market  fluctuations,  Generation  enters  into  physical  contracts  as well as
derivative  contracts,  including forwards,  futures,  swaps, and options,  with
approved  counterparties to hedge its anticipated exposures.  The maximum length
of time over which cash flows related to energy  commodities are currently being
hedged is four years.  Generation  has an estimated  88% hedge ratio in 2003 for
its energy  marketing  portfolio.  This hedge ratio represents the percentage of
Generation's  forecasted aggregate annual generation supply that is committed to
firm sales,  including  sales to ComEd and PECO's retail load.  ComEd and PECO's
retail load assumptions are based on forecasted  average demand. The hedge ratio
is not fixed and will vary from time to time depending  upon market  conditions,
demand,  and energy  market  option  volatility  and actual  loads.  During peak
periods,  the amount hedged  declines to meet the  commitment to ComEd and PECO.
Market  price  risk  exposure  is the risk of a change in the value of  unhedged
positions.  Absent any opportunistic  efforts to mitigate market price exposure,
the  estimated  market price  exposure for  Generation's  non-trading  portfolio
associated with a ten percent  reduction in the annual average  around-the-clock
market price of  electricity  is an  approximately  $39 million  decrease in net
income, or approximately  $0.12 per share. This sensitivity assumes an 88% hedge
ratio and that price  changes  occur evenly  throughout  the year and across all
markets. The sensitivity also assumes a static portfolio.  Generation expects to
actively manage its portfolio to mitigate market price exposure.  Actual results
could differ depending on the specific timing of, and markets affected by, price
changes, as well as future changes in Generation's portfolio.

Proprietary Trading Activities

         Generation uses financial  contracts for proprietary  trading purposes.
Proprietary  trading  includes all contracts  entered into purely to profit from
market price  changes as opposed to hedging an exposure.  These  activities  are
accounted for on a mark-to-market  basis. The proprietary trading activities are
a complement to  Generation's  energy  marketing  portfolio and represent a very
small portion of its overall energy marketing activities. For example, the limit
on open positions in electricity  for any forward month  represents less than 1%
of  Generation's  owned  and  contracted  supply  of  electricity.  The  trading
portfolio is subject to stringent risk management limits and policies, including
volume, stop-loss and value-at-risk limits.

         Generation's  energy  contracts  are  accounted for under SFAS No. 133,
"Accounting for Derivative  Instruments and Hedging  Activities" (SFAS No. 133).
Most  non-trading  contracts  qualify for the normal  purchases and normal sales
exemption to SFAS No. 133 discussed in the Critical Accounting Estimates section
of  Management's  Discussion  and Analysis of Financial  Condition and Result of
Operations  of the 2002 Form 10-K.  Those that do not are  recorded as assets or
liabilities  on the balance  sheet at fair  value.  Changes in the fair value of
qualifying hedge contracts are recorded in Other Comprehensive Income (OCI), and
gains and losses are  recognized  in earnings  when the  underlying  transaction
occurs. Changes in the fair value of derivative contracts that do not meet hedge
criteria under SFAS No. 133 and the  ineffective  portion of hedge contracts are
recognized in earnings on a current basis.

         The  following  detailed  presentation  of the trading and  non-trading
marketing  activities  at  Generation  is included  to address  the  recommended
disclosures  by  the  energy  industry's   Committee  of  Chief  Risk  Officers.
Generation  does  not  consider  its  proprietary  trading  to be a  significant
activity  in its  business;  however,  Generation  believes it is  important  to
include these risk management disclosures.

         The  following  table  describes  the  drivers of  Generation's  energy
trading and marketing business and gross margin included in the income statement
for the three  months  ended  March 31,  2003.  Normal  operations  and  hedging
activities  represent the marketing of electricity  available from  Generation's
owned or contracted  generation,  including  ComEd and PECO's retail load,  sold
into  the  wholesale  market.  As the  information  in  this  table  highlights,
mark-to-market  activities represent a small portion of the overall gross margin
for  Generation.  Accrual  activities,  including  normal  purchases  and sales,
account for the  majority of the gross  margin.  The  mark-to-market  activities
reported  here are those  relating  to  changes  in fair  value due to  external
movement  in  prices.  Further  delineation  of  gross  margin  by the  type  of
accounting  treatment typically afforded each type of activity is also presented
(i.e., mark-to-market vs. accrual accounting treatment).

         The  majority  of  Generation's   contracts  are  non-exchange   traded
contracts  valued using prices  provided by external  sources,  primarily  price
quotations  available through brokers or  over-the-counter,  on-line  exchanges.
Prices  reflect the average of the bid-ask  midpoint  prices  obtained  from all
sources  that  Generation  believes  provide  the  most  liquid  market  for the
commodity.  The terms for which such price  information  is available  varies by
commodity,  by region and by product.  The  remainder  of the assets  represents
contracts for which  external  valuations are not  available,  primarily  option
contracts.  These  contracts  are  valued  using the Black  model,  an  industry
standard option  valuation  model.  The fair values in each category reflect the
level of forward  prices  and  volatility  factors as of March 31,  2003 and may
change  as a result  of  changes  in  these  factors.  Management  uses its best
estimates to determine the fair value of commodity and  derivative  contracts it
holds and sells.  These estimates  consider  various factors  including  closing
exchange and over-the-counter price quotations,  time value,  volatility factors
and credit exposure.  It is possible,  however,  that future market prices could
vary from those used in recording  assets and liabilities  from energy marketing

         The following table,  which presents  maturity and source of fair value
of mark-to-market energy contract net assets, provides two fundamental pieces of
information.  First,  the  table  provides  the  source  of fair  value  used in
determining the carrying amount of Generation's  total


                                      103



mark-to-market asset or liability.  Second, this table provides the maturity, by
year, of Generation's net assets/liabilities, giving an indication of when these
mark-to-market amounts will settle and generate or require cash.

     (1)  Mark-to-market gains and losses on contracts that qualify as cash flow
          hedges are recorded in other comprehensive income.

     (2)  Mark-to-market  gains  and  losses  on  other  non-trading  derivative
          contracts  that do not  qualify as cash flow  hedges are  recorded  in
          earnings.

     (3)  Mark-to-market  gains and losses on trading  contracts are recorded in
          earnings.

     (4)  Following the recommendations of the Committee of Chief Risk Officers,
          the average tenor of the proprietary  trading  portfolio  measures the
          average time to collect value for that portfolio.  Generation measures
          the tenor by separating positive and negative mark-to-market values in
          its proprietary  trading portfolio,  estimating the mid-point in years
          for  each  and  then  reporting  the  highest  of the  two  mid-points
          calculated.   In  the  event  that  this   methodology   resulted   in
          significantly  different  absolute values of the positive and negative
          cash flow streams, Generation would use the mid-point of the portfolio
          with the largest cash flow stream as the tenor.

         The table below  provides  details of effective  cash flow hedges under
SFAS No. 133 included in the balance sheet as of March 31, 2003. The data in the
table gives an indication of the magnitude of SFAS No. 133 hedges Generation has
in place, however,  given that under SFAS No. 133 not all hedges are recorded in
OCI,  the table does not  provide an  all-encompassing  picture of  Generation's
hedges.   The  table  also  includes  a  roll-forward   of   Accumulated   Other
Comprehensive  Income on the  Consolidated  Balance  Sheets related to cash flow
hedges for the three  months ended March 31,  2003,  providing  insight into the
drivers of the changes (new hedges entered into during the period and changes in
the value of existing hedges). Information related to energy merchant activities
is presented separately from interest rate hedging activities.

(1) Includes interest rate hedges at Generation.


         Generation uses a  Value-at-Risk  (VaR) model to assess the market risk
associated with financial  derivative  instruments  entered into for proprietary
trading  purposes.  The measured  VaR  represents  an estimate of the  potential
change in value of Generation's proprietary trading portfolio.

         The VaR estimate  includes a number of assumptions about current market
prices,  estimates of volatility and correlations between market factors.  These
estimates,  however, are not necessarily indicative of actual results, which may
differ  because  actual  market rate  fluctuations  may differ  from  forecasted
fluctuations and because the portfolio may change over the holding period.

         Generation  estimates  VaR  using  a model  based  on the  Monte  Carlo
simulation  of  commodity  prices that  captures  the change in value of forward
purchases  and sales as well as option  values.  Parameters  and values are back
tested daily  against  daily  changes in  mark-to-market  value for  proprietary
trading  activity.  VaR assumes that normal market  conditions  prevail and that
there are no changes in positions.  Generation  uses a 95% confidence  interval,
one-day holding period,  one-tailed  statistical measure in calculating its VaR.
This means that  Generation  may state that there is a one in 20 chance  that if
prices move against its portfolio positions, its pre-tax loss in liquidating its
portfolio  in a one-day  holding  period  would  exceed the  calculated  VaR. To
account for unusual events and loss of liquidity,  Generation  uses stress tests
and scenario analysis.

         For financial  reporting purposes only,  Generation  calculates several
other VaR  estimates.  The higher the confidence  interval,  the less likely the
chance  that  the VaR  estimate  would be  exceeded.  A  longer  holding  period
considers  the effect of  liquidity  in being  able to  actually  liquidate  the
portfolio.  A two-tailed  test  considers  potential  upside in the portfolio in
addition to the potential downside in the portfolio considered in the one-tailed
test. The following table provides the VaR for all proprietary trading positions
of Generation as of March 31, 2003.

Credit Risk
Generation
         Generation has credit risk associated with counterparty  performance on
energy  contracts which  includes,  but is not limited to, the risk of financial
default or slow payment.  Generation  manages  counterparty  credit risk through
established policies,  including  counterparty credit limits, and in some cases,
requiring deposits and letters of credit to be posted by certain counterparties.
Generation's  counterparty  credit  limits  are  based on a scoring  model  that
considers a variety of factors,  including leverage,  liquidity,  profitability,
credit  ratings and risk  management  capabilities.  Generation has entered into
payment netting agreements or enabling agreements that allow for payment netting
with  the  majority  of its  large  counterparties,  which  reduce  Generation's
exposure to counterparty  risk by providing for the offset of amounts payable to
the counterparty  against amounts  receivable from the counterparty.  The credit
department  monitors current and forward credit exposure to  counterparties  and
their affiliates, both on an individual and an aggregate basis.

         The  following  table  provides   information  on  Generation's  credit
exposure,  net of collateral,  as of March 31, 2003. It further  delineates that
exposure by the credit rating of the counterparties and provides guidance on the
concentration of credit risk to individual  counterparties  and an indication of
the maturity of a company's credit risk by credit rating of the  counterparties.
The table below does not include  sales to  Generation's  affiliates or exposure
through Independent System Operators.

         Generation is a counterparty to Dynegy in various energy  transactions.
In early  July 2002,  the credit  ratings  of Dynegy  were  downgraded  to below
investment grade by two credit rating agencies. As of March 31, 2003, Generation
had a net receivable  from Dynegy of  approximately  $4 million and,  consistent
with the terms of the existing credit  arrangement,  has received  collateral in
support of this  receivable.  Generation  also has credit risk  associated  with
Dynegy through  Generation's equity investment in Sithe. Sithe is a 60% owner of
the Independence  generating  station, a 1,040-MW  gas-fired  qualified facility
that has an energy-only  long-term tolling agreement with Dynegy, with a related
financial  swap  arrangement.  As of March 31, 2003,  Sithe had recognized an
asset on its balance  sheet  related to the fair market  value of the  financial
swap agreement with Dynegy that is marked-to-market  under the terms of SFAS No.
133. If Dynegy is unable to fulfill the terms of this agreement,  Sithe would be
required to impair this financial swap asset.  Generation estimates,  as a 49.9%
owner of Sithe,  that the impairment  would result in an after-tax  reduction of
Generation's equity earnings of approximately $13 million.

         In addition to the  impairment of the financial  swap asset,  if Dynegy
were unable to fulfill its  obligations  under the financial  swap agreement and
the tolling agreement, Generation may incur a further impairment associated with
Independence.

         Additionally,  the future  economic value of AmerGen's  purchased power
arrangement  with  Illinois  Power  Company,  a subsidiary  of Dynegy,  could be
impacted by events related to Dynegy's financial condition.

Interest Rate Risk
ComEd
         ComEd uses a combination of fixed rate and variable rate debt to reduce
interest rate exposure.  Interest rate swaps may be used to adjust exposure when
deemed   appropriate   based  upon  market   conditions.   ComEd  also  utilizes
forward-starting interest rate swaps and treasury rate locks to lock in interest
rate levels in anticipation of future  financing.  These strategies are employed
to maintain the lowest cost of capital. At March 31, 2003, ComEd had settled all
of its forward-starting interest rate swaps.

         ComEd has entered into  fixed-to-floating  interest rate swaps in order
to maintain its targeted percentage of variable rate debt,  associated with debt
issuances in the  aggregate  amount of $485 million  fixed-rate  obligation.  At
March 31, 2003, these interest rate swaps, designated as fair value hedges,  had
an  aggregate  fair  market  value of $42  million  based on the  present  value
difference between the contract and market rates at March 31, 2003.

         The aggregate fair value of the interest rate swaps, designated as fair
value  hedges,  that would have  resulted  from a  hypothetical  50 basis  point
decrease in the spot yield at March 31, 2003 is estimated to be $49 million.  If
these  derivative  instruments  had been  terminated  at March  31,  2003,  this
estimated  fair  value   represents  the  amount  that  would  be  paid  by  the
counterparties to ComEd.

         The aggregate fair value of the interest rate swaps, designated as fair
value  hedges,  that would have  resulted  from a  hypothetical  50 basis  point
increase in the spot yield at March 31, 2003 is estimated to be $34 million.  If
these  derivative  instruments  had been  terminated  at March  31,  2003,  this
estimated fair value represents the amount to be paid by the  counterparties  to
ComEd.

PECO
         In February  2003,  PECO entered into  forward-starting  interest  rate
swaps in the aggregate amount of $360 million to lock in interest rate levels in
anticipation of future financings. At March 31, 2003, these interest rate swaps,
designated as cash flow hedges,  had a fair market value exposure of $2 million.
The debt  issuances  that  these  swaps  are  hedging  are  considered  probable
therefore,  PECO has accounted  for these  interest  rate swap  transactions  as
hedges.  In  connection  with PECO's April 28, 2003  issuance of $450 million in
First and Refunding  Mortgage Bonds,  PECO settled the swaps for a payment of $1
million, which will be recorded in other comprehensive income and amortized over
the life of the debt issuance.

         PECO has  entered  into  interest  rate swaps to manage  interest  rate
exposure  associated with the floating rate series of transition bonds issued to
securitize PECO's stranded cost recovery. At March 31, 2003, these interest rate
swaps had an aggregate  fair market value  exposure of $16 million  based on the
present  value  difference  between the  contract  and market rates at March 31,
2003.

         PECO also has  interest  rate  swaps in place to  satisfy  counterparty
credit  requirements in regards to the floating rate series of transition  bonds
which are mirror  swaps of each other.  These swaps are not  designated  as cash
flow hedges;  therefore,  they are required to be marked-


                                      108


to-market if there is a  difference  in their  values.  Since these swaps offset
each other, a mark-to-market adjustment is not expected to occur.

         The aggregate fair value exposure of the interest rate swaps that would
have resulted from a  hypothetical  50 basis point decrease in the spot yield at
March 31, 2003 is estimated to be $17 million.  If these derivative  instruments
had been terminated at March 31, 2003, this estimated fair value  represents the
amount that would be paid by PECO to the counterparties.

         The aggregate fair value exposure of the interest rate swaps that would
have resulted from a  hypothetical  50 basis point increase in the spot yield at
March 31, 2003 is estimated to be $14 million.  If these derivative  instruments
had been terminated at March 31, 2003, this estimated fair value  represents the
amount to be paid by PECO to the counterparties.

Generation
         Generation  uses a combination  of fixed rate and variable rate debt to
reduce  interest rate  exposure.  Generation  also uses interest rate swaps when
deemed  appropriate  to adjust  exposure  based upon  market  conditions.  These
strategies  are  employed  to achieve a lower cost of  capital.  As of March 31,
2003, a hypothetical 10% increase in the interest rates associated with variable
rate debt would not have a material  impact on  pre-tax  earnings  for the first
quarter of 2003.

         Under the terms of the Sithe Boston Generation, LLC (currently known as
Exelon  Boston  Generating,  LLC (EBG))  credit  facility,  EBG is  required  to
effectively  fix the  interest  rate on 50% of  borrowings  under  the  facility
through its maturity in 2007. As of March 31, 2003,  Generation has entered into
interest rate swap agreements, which have effectively fixed the interest rate on
$861 million of notional principal,  or 83% of borrowings  outstanding under the
EBG credit  facility at March 31, 2003.  The fair market value exposure of these
swaps, designated as cash flow hedges, is $92 million.

         The aggregate fair value exposure of the interest rate swaps designated
as cash flow hedges that would have resulted from a hypothetical  50 basis point
decrease in the spot yield at March 31, 2003 is estimated to be $108 million. If
the derivative instruments had been terminated at March 31, 2003, this estimated
fair value represents the amount Generation would pay to the counterparties.

         The aggregate fair value exposure of the interest rate swaps designated
as cash flow hedges that would have resulted from a hypothetical  50 basis point
increase in the spot yield at March 31, 2003 is estimated to be $77 million.  If
the derivative instruments had been terminated at March 31, 2003, this estimated
fair value represents the amount Generation would pay to the counterparties.

Equity Price Risk
Generation
         Generation  maintains  trust  funds,  as  required  by the NRC, to fund
certain  costs of  decommissioning  its nuclear  plants.  As of March 31,  2003,
decommissioning   trust  funds  are  reflected  at  fair  value  on  Exelon  and
Generation's  Consolidated  Balance  Sheets.  The mix of securities in the trust
funds is designed to provide returns to be used to fund  decommissioning  and to
compensate for inflationary  increases in decommissioning  costs.  However,  the
equity securities in the trust funds are exposed to price fluctuations in equity
markets,  and the value of fixed rate,  fixed income  securities  are exposed to
changes  in  interest  rates.   Generation   actively  monitors  the  investment
performance  of the trust funds and  periodically  reviews  asset  allocation in
accordance  with  Generation's  nuclear  decommissioning  trust fund  investment
policy.  A  hypothetical  10% increase in interest  rates and decrease in equity
prices would  result in a $175 million  reduction in the fair value of the trust
assets.

ITEM 4.           CONTROLS AND PROCEDURES

Exelon
         Within  the 90  days  prior  to  the  date  of  this  Report,  Exelon's
management,  including the principal  executive officer and principal  financial
officer,  evaluated Exelon's  disclosure  controls and procedures related to the
recording,  processing,  summarization  and reporting of information in Exelon's
periodic  reports  that it files with the SEC.  These  disclosure  controls  and
procedures have been designed to ensure that (a) material  information  relating
to Exelon,  including its consolidated  subsidiaries,  is made known to Exelon's
management,  including  these  officers,  by other  employees  of Exelon and its
subsidiaries,  and (b) this  information  is  recorded,  processed,  summarized,
evaluated and reported, as applicable,  within the time periods specified in the
SEC's rules and forms. Due to the inherent  limitations of control systems,  not
all  misstatements  may be  detected.  These  inherent  limitations  include the
realities that judgments in  decision-making  can be faulty and that  breakdowns
can occur because of simple error or mistake.  Additionally,  controls  could be
circumvented  by the  individual  acts of some persons or by collusion of two or
more people.  Exelon's controls and procedures can only provide reasonable,  not
absolute,  assurance that the above objectives have been met. Also,  Exelon does
not control or manage  certain of its  unconsolidated  entities and as such, the
disclosure  controls  and  procedures  with  respect to such  entities  are more
limited than those it maintains with respect to its consolidated subsidiaries.
         As of the date of their  evaluation,  these  officers  concluded  that,
subject to limitations  noted above,  the design of the disclosure  controls and
procedures  provide   reasonable   assurance  that  they  can  accomplish  their
objectives.  Exelon continually  strives to improve its disclosure  controls and
procedures  to enhance the quality of its  financial  reporting  and to maintain
dynamic systems that change as conditions warrant.
         There have been no significant changes in Exelon's internal controls or
in other factors that could  significantly  affect these controls  subsequent to
the date of their evaluation.

PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

Generation

         As  previously  reported  in the 2002 Form 10-K,  during 1989 and 1991,
actions were brought in Federal and state courts in Colorado  against  ComEd and
its subsidiary,  Cotter Corporation  (Cotter),  seeking  unspecified damages and
injunctive  relief based on allegations  that Cotter  permitted  radioactive and
other  hazardous  material  to be  released  from its mill into  areas  owned or
occupied by the plaintiffs,  resulting in property damage and potential  adverse
health  effects.  In June  2001,  a trial  for a  sub-group  of  plaintiffs  was
completed,  and the jury  returned  a verdict  against  Cotter and  awarded  $16
million in various  damages.  In November  2001,  the District  Court entered an
amended final judgment, which included an award of both


                                      112


pre-judgment  and  post-judgment   interests,   costs,  and  medical  monitoring
expenses,  which total $43 million.  In November 2000, another trial involving a
separate  sub-group of 13 plaintiffs was completed in Federal  district court in
Denver.  The jury awarded  nominal damages of $42,500 to 11 of 13 plaintiffs and
required Cotter to perform periodic medical monitoring at a cost of $241,000. On
April 22, 2003,  the Tenth Circuit Court of Appeals  reversed both judgments and
remanded the cases for retrial.

         On June 1, 2001, the U.S. Environmental  Protection Agency (EPA) issued
to EBG a Notice  of  Violation  (NOV)  and  Reporting  Requirement  pursuant  to
Sections  113 and 114 of the Clean Air Act,  alleging  numerous  exceedances  of
opacity  limits and  violations  of  opacity-related  monitoring,  recording and
reporting requirements at Mystic Station in Everett,  Massachusetts.  On January
8, 2002,  the EPA  indicated  that it had  decided to resolve the NOV through an
administrative  compliance  order and a judicial civil penalty action.  In March
2002,  the EPA issued and Sithe  Mystic LLC, a wholly owned  subsidiary  of EBG,
voluntarily  entered a Compliance  Order and Reporting  Requirement  (Compliance
Order)  regarding  Mystic  Station,  under which Mystic  Station  installed  new
ignition equipment on three of the four units at the plant.  Mystic Station also
undertook an extensive opacity monitoring and testing program for all four units
at the plant to help  determine if additional  compliance  measures were needed.
Pursuant to the requirements of the Compliance  Order, EBG switched three of the
four units to a lower sulfur fuel oil by June 1, 2002. The Compliance Order does
not address civil penalties. By a letter dated April 21, 2003, the United States
Department of Justice  notified EBG that, at the request of the EPA, it intended
to bring a civil penalty action, but also offered the opportunity to resolve the
matter through settlement  discussions.  EBG is pursuing settlement  discussions
with the EPA and the United States Department of Justice.


ITEM 5.  OTHER INFORMATION

ComEd
         As  previously  reported  in the 2002 Form  10-K,  in July  2002,  FERC
conditionally  approved  ComEd's  decision to join PJM. On April 1, 2003,  ComEd
received approval from FERC to transfer control of ComEd's  transmission  assets
to PJM.  FERC also  accepted  for filing the PJM tariff  amended to reflect  the
inclusion of ComEd and other new members,  subject to a compliance filing, which
was made on May 1, 2003, and to hearing on certain issues.  After  resolution of
these  matters  and  completion  of certain  implementation  work  necessary  to
integrate  ComEd into PJM, ComEd expects to transfer  control of its Open Access
Same Time Information System to PJM on June 1, 2003, and to transfer  functional
control  of its  transmission  assets to PJM and to  integrate  fully into PJM's
energy market structures on October 1, 2003.

         As previously  reported in the 2002 Form 10-K, on March 3, 2003,  ComEd
entered  into  an  agreement  with  various  Illinois   electric  retail  market
suppliers,  key  customer  groups and  governmental  parties  regarding  several
matters affecting ComEd's rates for electric service.  The Agreement  addressed,
among other things, issues related to ComEd's residential delivery services rate
proceeding,  market value index proceeding,  the process for competitive service
declarations  for  large-load  customers  and  an  extension  of  the  PPA  with
Generation.  On March  28,  2003,  the ICC  issued  orders  consistent  with the
Agreement.  Rehearing  requests  were  filed  with  the ICC in April  2003.  The
Agreement will not become effective as long as any of the ICC orders are subject
to any pending rehearing request.

PECO
         As previously  reported in the 2002 Form 10-K, on August 15, 2002,  the
International Brotherhood of Electrical Workers (IBEW) filed a petition with the
NLRB to conduct a  unionization  vote of certain of PECO's  employees.  National
Labor  Relations  Board  (NLRB)  hearings  were  completed  and a  Decision  and
Direction of Election (DD&E) was issued on April 21, 2003.  Regulations  require
that the election be conducted within 30 days of the DD&E issuance.

         As previously  reported in the 2002 Form 10-K, the PUC's Final Electric
Restructuring   Order   established  MSTs  to  promote   competition.   The  MST
requirements  provided  that,  if as of  January  1,  2003,  less  than  50%  of
residential  customers were taking electric  service from  alternative  electric
generation supplier, the number of customers sufficient to meet the MST would be
randomly selected and assigned to an alternative  electric generation  suppliers
through a  PUC-determined  process.  On January 1, 2003, the number of customers
choosing an alternative  electric  generation  supplier did not meet the MST. In
February 2003,  PECO filed a residential  customer MST plan, and on May 1, 2003,
the PUC approved the plan.  The approved  plan  provides for a two-step  process
with a total of up to 400,000 residential customers being transferred to winning
alternative  electric  generation  supplier bidders: up to 100,000 in July 2003,
and another  300,000 in December 2003. Any customer  transferred  would have the
right to return to PECO at any time.

Generation
         As   previously   reported  in  the   December   31,  2002  Form  10-K,
approximately  1,700 of  Generation's  7,200 employees are covered by Collective
Bargaining  Agreements  (CBA) with the IBEW. On April 9, 2003,  the IBEW filed a
petition with the NLRB to represent all production and maintenance  employees in
Generation's fossil and hydroelectric  operations in the Mid-Atlantic  operating
group. These

                                      113



employees are not currently  covered by a CBA. The IBEW petition  estimates that
the  number  of  additional  employees  represented  would  be 350 to 400.  NLRB
hearings were  conducted in April 2003. An election is anticipated in the second
half of 2003.
